THE cost of materials which are used for food comes to one half or more of the average income of at least ninety per cent of the people of this country ; yet our product of food mate- rial is more abundant in ratio to population than that of any other country which holds a prominent position in the civilized world. This food consists in greatest measure of grain, meat, dairy prod- ucts, and roots or tubers ; in small part of fish, green vegetables, and fruit. The greater part of this food must be converted into a digestible and appetizing form by the application of heat to it at the right temperature, the degree varying with different kinds of food ; this heat must be applied for a suitable time, also varying with the kind of material which is to be converted into a nutri- tious form by its action. Yet there are no popular treatises or definite instructions on the scientific application of heat to food. Good health depends in greater measure upon adequate nutri- tion and upon the conversion of food material into a digestible form than upon any other factor in life. A well-nourished man can bear adverse conditions of life in the dwelling-house, the factory, the mine, and the furnace, to which the ill-nourished man will succumb in a very short time. On the other hand, the ca- pacity of the man to perform his work is as fully dependent upon the quality and adequacy of his food as the capacity of the horse, ox, or mule. The force of the man depends on his food as much as the force of the engine upon the fuel used under the * This essay has been prepared for the American Public Health Association : delivered at their meeting in Brooklyn, October 23, 1889.

There are innumerable treatises upon the feeding of animals ; upon the generation of steam ; upon the construction and ventila- tion of buildings ; upon the arts which relate to clothing the hu- man body, and upon keeping the dwelling and workshop warm ; and, lastly, yet more numerous treatises or cookery-books upon the art of mixing and preparing the food which is to be cooked ; there are also many treatises, chemical and physiological, upon the subject of nutrition, and there are one or two treatises on the science of cooking, notably Dr. Mattieu Williams's " Chemistry of Cookery " ; yet, so far as the writer has been able to ascertain the facts, there is no receipt-book or cookery-book in common use which deals with the actual art of cooking by directing the right application of heat for a suitable time and at a suitable degree, to the specific food which is to be converted into a nutritious form by the conversion of its elements into new forms or conditions by the action of heat upon it. It is possible that greater attention has been given to this mat- ter in England than in this country. After trying in vain to find an oven thermometer in the United States, I lately imported one from England, made by Joseph Davis & Co., Fitzroy Works, Lon- don, S. E., and purchased at an agricultural show at retail for seven shillings sixpence, gauged at 200° to 600° Fahrenheit. On this thermometer are marked the respective degrees to which vari- ous kinds of food should be subjected, as follows : Pork 320° Fahr. Veal 320 " Beef 310 " Mutton 300 " Puff pastry 340° Fahr. Bread 340 " Pastry 320 " Meat-pie 290 " These figures agree substantially with my own experiments as to the maximum of heat, but I do not concur with the inference that less than 200° Fahr. may not be permitted, if time be given for the lower degree of heat to do its work. On the contrary, any kinds of very tough meat may be reduced to a very tender condi- tion by the long application of heat at 180° to 200°, without loss of flavor or nutritious property, provided the food be put into sub- stantially air-tight vessels. The testimony of Dr. Mattieu Will- iams is conclusive on this point, as well as the special knowledge of the few good cooks of the method of simmering as distin- guished from boiling. Meats and grains may be most nutritiously cooked at less than a boiling heat, and eggs should always be ; while most kinds of roots, tubers, and vegetables require a higher degree. I venture now to give some of the general conclusions which I have reached by the application of somewhat crude methods and THE ART OF COOKING. 3 inventions on "which I have experimented personally in such scraps of time as I could spare from my regular occupation, and on nearly two years' use of my apparatus in my own family. I will challenge attention and discussion by first submitting some very positive and dogmatic statements, subsequently sus- taining them by such proofs as I have to offer : 1. Special apparatus for boiling and frying has been adequate- ly and suitably developed for the use of those who can afford these somewhat wasteful methods of preparing food, yet excellent when skillfully practiced. 2. The ordinary methods of frying are utterly bad and wasteful. 3. Bread may be baked suitably in a brick oven, and also eco- nomically, when the work is done upon a large scale. 4. It is very difficult to bake bread in a suitable way in the common iron stove or range ; for this, among other reasons, most of the bread consumed in this country is very bad, although we have the greatest abundance of the best material. 5. Meats may be well roasted in a costly manner before an open fire. 6. Aside from the exceptional apparatus or methods named, substantially all the modern cooking stoves and ranges are waste- ful and more or less unsuitable for use. All the ordinary meth- ods of quick baking, roasting, and boiling are bad ; and, finally, almost the whole of the coal or oil used in cooking is wasted. 7. The smell of cooking in the ordinary way gives evidence of waste of flavor as well as a waste of nutritious properties ; ana in most cases the unpleasant smell also gives evidence that the food is being converted into an unwholesome condition, conducive to indigestion and dyspepsia. 8. Nine tenths of the time devoted to watching the process of cooking is wasted ; and the heat and discomfort of the room in which the cooking is done are evidence of worse than waste. 9. The warming of the room or house with the apparatus used for cooking is inconsistent with the best method of cooking, and might be compassed at much less cost if the process of cooking were separated from the process of warming the room or dwelling. 10. No fuel which can not be wholly consumed is fit to use in the process of cooking, and any chimney which creates a draught upon the fuel when in the process of combustion, like the ordi- nary chimney of a house, is worse than useless, since it wastes the greater part of the heat generated from the fuel. The true science of cooking consists in the regulated and con- trolled application of heat by which flavors are developed and the work of conversion is accomplished. For this purpose a quantity of fuel is required which is almost absurdly small compared to the quantity commonly used. 4 THE POPULAR SCIENCE MONTHLY. Compare the ordinary method of using fuel for cooking with the scientific use of fuel for the development of power in the steam-engine. The sheet of lightly sized linen paper abstracted from the un- used part of an old ledger, on which I am now writing the first draught of this essay, measures 13" X 9" = 117 square inches, and weighs half an ounce. In solid form it measures half a cubic inch. If consumed under the boiler of the modern marine steam- engine such as is used in the freight-steamers that carry our wheat to England, two sheets of this paper in a solid form would be equal to seventy-one per cent of the calorific value of a cube of bituminous coal of the same size, and would drive a ton of wheat and its pro- portion of the steamship 1 fo miles on the way from the producer to the consumer at the present standard of power developed from coal. Yet not over twelve per cent of the actual power of the heat which this scrap of paper will yield would even then be act- ually converted into work. A cube of pure wood-pulp of the same size will do the same work. On the other hand, wood-pulp until ignited is the best available non-conductor of heat ; I there- fore build my ovens in greater part of wood-pulp prepared so as not to ignite at any degree of heat which is necessary for cooking ; but even in my oven it requires one quart of oil, measuring a frac- tion under fifty-eight cubic inches, to cook fifty to sixty pounds of bread, meat, and vegetables in four successive charges occupying two hours each. Compared with the application of heat to the development of power, even my oven must be utterly condemned aswasteful of fuel ; but compare my quart of oil with the hod- f uls of coal that would be required to cook sixty pounds of food in the common range or stove, and then what is the verdict ? I now venture to submit the data of a dinner prepared by myself, but little out of the usual course, as an example of the common practice in my own family, and of what may be done substantially with one lamp. The dinner was provided for my own family of seven persons, with five guests, and it also sufficed for four servants — sixteen in all — with something left over. My summer kitchen is fitted with a cooking-stove, as it is more con- venient to use the top of the stove, heated with hard-wood chips, for boiling water, heating the soup, and boiling potatoes, than it is to use a kerosene-oil stove of the common kind ; on this stove the soup made the day before in the Aladdin cooker was reheated, the potatoes were boiled, and the hot water was provided. The dinner cooked in the Aladdin oven consisted of three to four pounds of fresh blue-fish, just caught, cooked in imitation of broiling, one hour; six to seven pounds leg and loin of lamb, roasted one and three fourths hours ; three tame ducks, weighing about seven pounds, roasted one hour ; squash cooked in its own THE ART OF COOKING. 5 juice, with but very little water, one and three fourths hours ; stuffed tomatoes cooked three quarters of an hour ; a large apple souffle pudding baked one hour. The oven having been previously heated one hour, the lamb and the squash were first put in ; later the fish was added ; while these were being served, the ducks and the pudding were being cooked ; the use of the lamp for the whole service was four hours ; the oil consumed, one pint, cost less than two cents ; the cook's es- timate of the coal which would have been required for the dinner had it been cooked in the large stove which has been used in other years, at one and a half to two ordinary hodfuls. This was an every-day dinner, to which my guests had been in- vited in order that they might test our common practice. I assume that the effect of heat upon food material is what may be called chemical conversion, accompanied, when the heat is ap- plied at a low degree only, by partial evaporation of water, but when applied at a high degree, by partial distillation of the juices, by the cracking or dissociation of the fats, and by the diffusion of the volatile parts of the food in bad smells with loss of flavor and waste of some of the nutritious properties of the material. If the cracking or dissociation of the fats is carried to a point which is very common in iron stoves and ranges, the residuum of the fat becomes very indigestible and positively unwholesome. When rightly cooked and not cracked or dissociated, a certain portion of fat is absolutely necessary to adequate nutrition. Is it not true that we take into our stomachs a great deal too much fat, and that it is eaten in the most injurious form ? The preparation of the coffee-berry is the most familiar exam- ple of the development of its properties by the right application of heat. If the berry is dried, ground, and made into an infusion without being roasted, no true or drinkable coffee can be made from it. If overheated and burned, the infusion is acrid and un- wholesome. But when the berry is carefully roasted and ground, the infusion makes true coffee. The flavor and other properties are the actual product of the heat, when scientifically applied. The flavor of the pea-nut is developed in the same way. In the treatment of grain, none yields so great a difference in flavor, according to the method of cooking, as the meal of maize or In- dian corn ; but I find the wheaten bread, whether made of whole or of bolted flour, yields a much finer flavor when baked two or three hours in my pulp oven at 250° to 300° Fahr., than when quickly baked in a common stove or range in one hour at an unknown but admittedly much higher degree of heat. The flavors of the white kinds of fish, such as cod, haddock, flounder, scup, and the like, which are much impaired by the ordinary methods of cooking, are very finely developed when slowly cooked in my 6 THE POPULAR SCIENCE MONTHLY. oven; and, lastly, all kinds of meat and poultry develop their respective flavors in the most appetizing manner when roasted in my pulp oven at such low degrees of heat as not to give off any smell or to dissociate any of the volatile elements of the juices or fats, while for game nothing can. equal it. Quail and partridge come out rich, juicy, and of almost too full a flavor. I have frequently served dinners or lunches of four or five courses — soup made the day before, reheated ; fish, meat, game, potatoes, cauliflower, asparagus, onions, tomatoes, and custard pudding — all cooked in the same oven at the same time in the dining-room, and served from the oven to the table in the china or earthen dishes in which each had been cooked ; the only differ- ence between one dish and another being in respect to the time in which it had been subjected to the heat of the lamp or lamps, yet without the least flavor or taint being carried from one kind of food to the other. It will be apparent that, if cooking can be done in this way, the whole art will consist in preparing the food according to writ- ten or printed receipts, and in determining the degree of heat and the time to which these dishes should be subjected. No watching is needed, and indeed none is possible without danger of cooling off the oven by opening it too often. Of course, it is better to use two ovens than one, devoting one to meat and fish, served by a lamp of moderate power for the right period of time, and the other served by a lamp of higher power for cooking vegetables, puddings, and pastry. My Aladdin ovens, so called, are adapted to methods of cook- ing corresponding to broiling, roasting, baking, and braising ; but they can also be used for boiling and simmering. My Aladdin cooker, so called, in which the heat is conveyed through water, is devoted wholly to boiling, stewing, and simmer- ing, especially the latter. I neither attempt nor desire to fry any- thing in either kind of apparatus. About nine tenths of all the cooking of my somewhat large family has been done with this apparatus for nearly two years, and I also have an office lunch- room for the use of about twenty employe's, in which no other apparatus is or can be used. My summer kitchen at my sea-side house is fitted with a grill which is very seldom used ; it proves to be most convenient to use the cooking-stove, heated with hard- wood chips, for boiling the water for tea and for occasional frying. My winter kitchen is a large one, and it depends upon the range for warming it. The range, therefore, continues to be used to some extent for cooking, mainly for preparing breakfast, but I contemplate substituting a special stove without any oven, which will heat the room with much less coal, the top of the stove being fitted for cooking in the ordinary way. Neither the oven of the THE ART OF COOKING. 7 stove in summer nor of the range in winter are now used for cooking ; therefore, the kitchen is never overheated and the food is never spoiled. We have occasionally failed to cook a large joint of meat for a sufficient time, but we have never spoiled a dish in the process of cooking since the pulp or jacketed oven was adopted. What, then, are the simple principles of the science of cook- ing ? I think they may be stated in a few very plain terms : 1. The heat should be derived from fuel which can be wholly consumed or wholly converted into the products of complete com- bustion without any chimney except that of the lamp or burner. The fault with coal, especially anthracite, is, that it is not evenly or fully consumed ; hence the need of a chimney to take away the gases developed and not wholly consumed ; but the chimney also carries off the greater part of the heat. It is very evident that the crude combustion of coal and the direct application of the heat generated will ere long give way to more scientific methods of consuming the gaseous products and of deriving the heat from the final combustion of the gaseous products in all arts. In the matter of cooking, kerosene-oil burned in any one of the types of lamp which have a central duct to convey oxygen from below to the inner side of a circular wick, when properly trimmed and served with well - distilled oil, gives substantially perfect com- bustion. The same may be said of illuminating gas when used in one of the burners of the Bunsen type which supply an excess of oxygen and yield the blue flame. The combustion of oil and of gas can be brought under abso lute control by gauging the size of wick or burner to the work to be done. 2. The oven in which the food is to be subjected to this meas- urable and controllable source of heat must be so constructed that the heat imparted to it may be entrapped and accumulated up to a certain measure or degree and then maintained at that tempera- ture without substantial variation until the work is done. This can be done by jacketing the oven in a suitable way with mate- rial which is incombustible and also a non-conductor of heat. 3. There should be no direct communication between the true oven or receptacle in which the food is placed and the source of heat, lest the products of incomplete combustion should some- times taint the food, and lest the food should be exposed to being in places burned or scorched. These three conditions are all accomplished in the two some- what crude and probably incomplete inventions which I have named the " Aladdin Cooker " and the " Aladdin Oven," in both of which the heat derived from common lamps, such as are used for 8 THE POPULAR SCIENCE MONTHLY. lighting, may be stored or accumulated so as to do the work of cooking in a very perfect manner. In the cooker the heat is im- parted to water in an attachment to a metal-lined wooden box corresponding to the water-back of the common range or stove, and the work is done by the contact of the hot water with the outside of the porcelain vessels in which the food is placed, or by the steam generated when the water is heated to the boiling-point. In the oven a column of heated air is carried from the chim- ney of the lamp to the inside of an outer oven made chiefly of prepared wood-pulp, but outside of the inner sheet-iron or metallic oven in which the food is placed, which inner oven is separately ventilated. I do not claim any originality in these simple principles or in the idea of jacketing an oven with non-conductors of heat. All these matters are well understood by every intelligent stove- manufacturer, but it is practically impossible for any one to apply them in making stoves such as will meet the demand of the mar- ket, for two reasons : 1. The greatest demand for stoves is that of people of very moderate means, who are too much controlled by the price in mak- ing a choice, making the common error in confounding cheapness with low price, an error which leads to great waste not only in the matter of stoves but in many other ways. 2. The absolute and imperative preference of the public for a stove in or upon which the work can be done very quickly. The custom of cooking quickly is in part a matter of choice, and in part due to the necessity to which a great many working people are subject to cook their meals quickly or else to go with- out hot breakfasts and dinners. Another great obstruction to improvement in the art of cook- ing is the almost universal misconception that the finer cuts of meat are more nutritious than the coarser portions, coupled with an almost universal prejudice among working people against stewed food. This prejudice is doubtless due to the tasteless quality of boiled meat ; boiling toughens each of the fine fibers, and deprives the meat almost wholly of its distinctive flavor. All these blunders and misconceptions must evidently be removed before any true art of cooking can become common practice. The more necessary, however, does it become to invent appa- ratus in which meat can only be simmered and can not boil, as in the Aladdin cooker, and also to invent a stove or oven in which neither meat nor bread can be overcooked, dried up, or rendered indigestible by too much heat, as in the Aladdin oven. Next, people must be persuaded that a better and more nutri- tious breakfast can be made ready to eat, as soon as the family THE ART OF COOKING. 9 are out of bed, by putting meat stews, oatmeal, brown bread, and many kinds of puddings, into the cooker, and simmering all night by the use of a single safe lamp, than in any other way. People must be taught that the dinner can be put into the oven when both husband and wife go to the mill to work, and so treated that it may be found perfectly cooked at noon, without requiring any attention in the interval. People must be taught that the best of bread, raised with good yeast, can be mixed and kneaded between 12.30 and 1 p. m., placed in a bread-raiser, which will raise it ready for the oven at 6 or 7 p. m., and that this bread may be perfectly baked in two hours by the heat of the evening lamp, which at the same time serves to give light for reading or sewing. All this can be accomplished with my crude apparatus, but, until some skillful stove-makers take up these inventions and make the ovens in large numbers at low cost, my own efforts must be directed mainly toward ameliorating the condition of the rich, saving the houses of the well-to-do from the heat and smell of the present bad methods, and in this way creating a demand for my ovens which, while made in small numbers by hand-work, are too costly for general use, although in an ordinary family they will pay for themselves in six months. I have ventured to call the attention of the Public Health As- sociation to these matters, because I have been led, by the study of the statistics of the cost of subsistence, to certain conclusions which are wholly in the line of your work. I venture to ask you if it is not a fact that bad and wasteful methods of consuming food are not a most potent cost of inability to work to the best advantage ? Are they not more promotive of disease, and, in fact, a more subtle cause of want in the midst of abundance, than even the waste on fermented and spirituous liquors ? From my own observations, I am of the opinion that dyspepsia is a cause of more disability than intemperance, although this proposition is not capable of statistical demonstration. Material life consists in the conversion of forces, or in the ap- plication of material products, to the supply of the necessities of life. In the line of absolute necessity food comes first, clothing next, and shelter third. The supply of the materials for meeting these needs of the body is superabundant ; comfort and welfare depend upon the relative proportion of the materials used, or upon the direction which may be given to the conversion of these forces. The result of each year's work is a given product ; whether that product shall be adequate or otherwise depends almost wholly upon individual intelligence. In respect to the great majority of all who perform the actual manual or mechanical wo^k of produc- io THE POPULAR SCIENCE MONTHLY. tion, if the expenditure for food and drink is unduly large, then either clothing or shelter must be restricted ; a small part of the waste of food, on which half the income is spent, might, if saved, enable the family to double the expenditure for a dwelling-place. It follows that the most difficult question with which practical reformers are called upon to deal, viz., that of providing more ample and comfortable dwellings, may be solved by altering the conversion of the present product, even if that may not be in- creased, so that what is now in part wasted on food and drink may be spent for better shelter, and yet the family may be more fully nourished than at present. I do not claim absolute accuracy for the following proportion of expenses in workingmen's fami- lies, but I am quite sure they are near enough to the mark to serve as an example. In a family of five adults, or of four adults and two children ten or under, making an average family of five persons, in which one half the income is spent for food and fuel, twenty-five cents a day per adult being spent for food, the corresponding average expenditure per adult : For clothing will be • V to 9 cents. For liquor it may be 2 to 4 " For sundries it will be about 5 " And the remainder for rent or shelter, if no liquor is used 9 to 1 1 " If liquor is used 1 to 9 " Now, I think it is very safe to put the waste of food material at twenty per cent, or five cents a day ; if this misspent force and one half the average cost of liquor, or two cents a day, could be converted into shelter — that is to say, to providing a more ample dwelling by either buying or leasing — it would suffice to enlarge the present quarters by one half to three fourths. Five cents a day per adult comes to $1,000,000,000 or more a year, counting two children of ten or under as equal to one adult. But the greater benefit which would come from a true art of preparing food would consist in the increase of the productive force of the community, so that the provision for dwelling might be increased both abso- lutely and relatively. I might add another treatise to this, on the waste of force in bad building and from the common practice of what I have named the art of combustible architecture ; but time will not serve. Suffice it that the product of this nation is more than ample for the abundant subsistence, the adequate shelter, and the complete clothing of every family in it ; yet we witness want in the midst of plenty, .because we waste enough to support another nation at the standard of French economy and thrift, especially in the matter of food. I may now venture to call your attention to some of the very subtile points which are brought out by the statistical investiga- THE ART OF COOKING. n tion of the food question. I suppose that there is no kind of meat which is consumed so generally or in such large quantity as pork ; yet, according to the chemical and physiological data, the conver- sion of Indian corn into pork, at the rate of one thousand pounds of corn to two hundred pounds of pork, results in a waste of prac- tically all the protein and nearly all the starch, and gives a re- siduum of fat of which most people get too much in the other kinds of food which they consume. Yet it would be useless to try to abolish pork from the common dietary. I sometimes wonder if the Hebrew lawgivers were not good economists when they con- demned the use of pork, or whether they were guided wholly by sanitary considerations. Again, the present crop of wheat calls for fifty thousand tons of twine for binding it upon the self -binding harvester ; the cost of binding wheat by hand was five to six cents per bushel, and it required a small army of agricultural tramps who charged almost any price when needed to do this work. The self-binder reduced this charge to not exceeding one cent and a half per bushel. This reduction, which finally took effect two or three years before the resumption of specie payments in this country in 1879, was one of the principal factors in enabling us to export wheat profit- ably and vastly in excess of anything previously known ; and it was upon the margin of exports over imports, consisting wholly of wheat, that we were enabled to import gold in sufficient meas- ure to resume specie payment. Yet this all turned on tying a knot by the machine instead of by hand. Again, I will present to you my diagram of the loaf of bread, which I have frequently used in other ways. You will observe that, with wheat at about the present price, bread can be made and can be sold in a very large way at three to three and one half cents per pound ; but if the bread is distributed in the customary man- ner by way of small shops or by delivery on the part of the bakers themselves, you will find that the price of bread ranges from five to eight cents a pound, according to the quality. Now, in this oven made of paper, any person of ordinary intel- ligence who is willing to devote twenty minutes to kneading bread — which requires more muscle than it does mind — then placing it in the bread-raiser, following a certain rule, taking it out at a given time and putting it in this oven over this lamp, can make better bread at three to three and one half cents per pound than any baker's bread which can be purchased. Here are samples of the bread ; you can taste it for yourselves. I devoted two evenings to learning how to make bread ; and I baked these loaves, some of which I made myself, by the heat of the evening lamp which lighted my library table while I was reading my evening paper. I have said that a saving of five cents per day per capita might 12 THE POPULAR SCIENCE MONTHLY. Chariton, Iowa October, 1883. Glyndon.

The foregoing table was made in 1883, when wheat was worth ninety cents a bushel on the far Western farms. The price of wheat, and the charges for transportation and milling, are now lower. The cost of distributing bread is now greater in proportion than it was in 1883. THE ART OF COOKING. 13 readily be made in the food-supply of an average family. The customary ration is from three fourths of a pound to a pound ; in the families of poor people, who depend very much upon bread, I suppose it is one pound. Now, wherever such a family is paying six cents a pound for wheat bread, not an uncommon price among the poor in Boston, a saving of two and one half cents a day can be made on bread only by making it in the family and baking it in this oven. But, again, this possibility leads to another consideration. It is conceivable that all the bread may by and by be made in this way. Then what would become of all the bakers ? They would for a time suffer for want of work ; but you will observe that in this as in most of the actual improvements in the conditions of so- ciety, the art which would be displaced is one of the most onerous kinds of labor, requiring long hours of night-work ; a greater abundance of bread would be furnished at less cost ; and pres- ently the bakers would be absorbed in other branches of work. How that happens, and how such adjustments are made, I suppose no one knows. There was formerly one branch of cotton-spin- ning, viz., the sizing of the warps, which was conducted under very uncomfortable if not unwholesome conditions. The old- fashioned dressing-machine, as it was called, on which all the warps of cotton goods were prepared with starch for weaving, was worked in a room at from 110° to 120° Fahr., the atmosphere be- ing impregnated with the smell of sour starch ; and in a given factory the work of eight men was required. In the year 1866 I was myself instrumental in importing two machines of a new kind from Great Britain ; these machines were operated in a light, cool, and well-ventilated room ; a man and a boy did the work of the eight men. What became of the other seven men ? I never could trace them ; they were merged in the great body of work- men. The new machine has wholly displaced the old one ; and there is now no branch of work in the cotton-mill which is con- sidered injurious, or subject to any great discomfort. In fact, when the final application of invention is made to the cotton-fac- tory by using ice or other methods of cooling the air in summer, as we use fuel to heat the rooms in winter, the atmosphere of the cotton-mill will become about the most salubrious that can be ob- tained, for the reason that the exact degree of heat and humidity which is called for in the best work in spinning and weaving is consistent with the exact degree required for the health of the human body ; and since electric lighting has displaced the nox- ious vapors of illuminating gas, it may soon become possible to secure workers in a cotton-mill on the ground that a cotton-mill is the best sanitarium.

I will now present to you the diagrams and description of the cooker and of the oven, and will presently invite you to test the quality of the food which has been prepared while I have been speaking. These two diagrams were first prepared in a rough way for a newspaj^er ; the form of the heater to the Aladdin cooker has been changed, and some cross-sections have been in- troduced in order to increase the heating surface. The Aladdin oven is made at the present time of a different shape and in a dif- ferent way ; but the two diagrams will show to you the two con- ceptions on which the whole matter is based. I have a strong suspicion, or I may even say a growing confi- dence, that I have really accomplished what Count Rumford un- dertook to do, but which he failed to establish permanently for want of a fuel like kerosene-oil or gas, which can be controlled, regulated, and thoroughly consumed. I may have spent a thousand dollars more or less in develop- ing this subject. The present very simple forms of apparatus have been adopted after considerable money had been wasted in more complex methods of reaching the same results. I believe this is the course in almost all inventions. I do not intend to be- come a manufacturer of ovens. I have made an arrangement with Messrs. Kenrick Brothers, of Brookline, who now make them on orders by hand- work, crediting me with a moderate commission from which I may ultimately recover what I have spent, although I have no great expectation of doing so. The ovens cost too much while they are made by hand ; it is my hope that some regular stove-manufacturer may take up the subject at the point to which I have brought it, and make a business of introducing my appa- ratus on strictly commercial methods. The price of the standard Aladdin oven like these which are before you, at the present time, is twenty-five dollars without the lamp, boxed and ready for delivery to express or railway. I hope they may ultimately be furnished, when made in a large way, for a considerably lower price ; but even at the present price they will pay for themselves in economy of fuel, in economy of food, and in the comfort of those who do the work, in a very short term of weeks rather than of months. I began the study of cooking apparatus many years ago, when endeavoring to aid factory operatives, during the period of very high-priced cotton, in supporting themselves on the wages which they could earn while the mills were running short time ; and I had substantially conceived the " Aladdin Cooker," but I did not then follow up the subject so as to enable me to boil water in this apparatus by means of a lamp, kerosene-oil not then having been THE ART OF COOKING. i7 introduced for such purpose. Moreover, I was under the old su- perstition that it was necessary to have a heat at or above the boil- ing-point in order to cook at all. Even Count Rumford found out by accident that meats could be cooked at a lower degree ; and it was not until I happened to read Dr. Mattieu Williams's " Chemistry of Cookery " that I was led to develop the Norwegian cooking-box into the cooker with the heating attachment. Perhaps I unwisely gave way this idea or conception which I might have patented : I had the impression that it would be adopted more rapidly ; but the public have become so accustomed to the patent system in this country as to make it almost impossible to give away even an idea. I doubt if this is altogether a whole- some condition, when manufacturers wait so long for the protec- tion of a patent before undertaking to make a good thing on a commercial scale. Nevertheless, one must accept the fact, and the cooker has not been taken up by any manufacturer. Warned by this lesson, I applied for a patent on my first " Aladdin Ovens," which were made wholly of metal, the outer oven being packed with non-heat-conducting material ; but on this application I failed ; this identical apparatus had been invented fifty years ago, the heat being derived from a pan of charcoal, and the patent had expired ; of course, the charcoal did not meet the necessary condi- tions. I found, however, that the oven made wholly of metal packed with carbonate of magnesia or fossil meal would be very expensive ; moreover, the outer metal skin wastes a great deal of heat. I then experimented with various compounds, and finally adopted the material of which these ovens are made, known as " indurated fiber," or paper pulp, prepared in a certain way under a patent and baked at a high heat. I applied for a patent on an oven made in this way, but the mere substitution of the pulp for the metal did not suffice to give me the patent asked for. There is therefore no patent on the construction of either of these devices. The names " Aladdin Cooker " and " Aladdin Oven " are my trade-marks, on which I may hope to hold a certain control, so that the ovens shall be made of safe material, incombustible at any de- gree of heat required for the work, and from which control I may possibly recover the money which I have spent on my experi- ments ; if I do not, it will be my contribution to the public service ; and if by this contribution I can do away with even a small part of the waste of good food material and with a small part of the indigestion caused by bad cooking, I shall consider myself fully compensated. Under such conditions I may perhaps venture upon the ordi- nary method of citing the testimony of some of the few persons who have bought these ovens and who have made use of them. I will first give a copy of a letter from an elderly lady who visited VOL. XXXVI. — 2 18 THE POPULAR SCIENCE MONTHLY. my office with, her daughter ; the latter was very skeptical as to success in working my apparatus ; the oven was, however, bought, and has been in use during the past summer ; her testimony in re- gard to it is as follows : I am glad to tell you that I like the Aladdin oven very much indeed. My din- ners for the last three months have been cooked in it with success and economy, and the kitchen never overheated. It saves material, fuel, and labor, as well as heat. It is an immense comfort as well as economy. It bakes bread and cake nicely, and we have only used coal for laundry purposes. I wish it could be pro- duced at a cheaper rate, though I would not lose mine for twice its price. Another certificate I may venture to give from another lady who has tried the apparatus, as follows : 1. In respect to economy in the use of material for food : All remnants of food can be served again without drying or losing any of the fresh flavor. With any skill, therefore, "made dishes" can be produced until the first material is used up. 2. In respect to comfort of the kitchen : It goes without saying that a room in which only a lamp is burning is cooler than one with a fire in an iron stove. 3. The cook says it is much less work ; but I find they sometimes from force of habit throw the fuel into the stove and cook there rather than take the trouble to use the oven. Lastly, general conclusions : It is of inestimable value in warm weather, and saves two hods of coal a day when it is used half the day. For an apartment- house or in small kitchens it will be a great boon. With an intelligent, care-loving woman it will go much further aud do better work, of course, than with the ordi- nary cook, though it is so simple that any one can use it. In a third letter, the testimony is as follows : My general conclusions in regard to health and appetizing conditions are : Bread from the oven is much more wholesome than from the range, because of the slow, even, and thorough baking. Meats are more wholesome, because the juices are entirely preserved and the fats not overdone. The greatest advantage, perhaps, is the possibility of so regulating the temperature as to preserve fine and delicate flavors at the same time that the most wholesome results are secured. Finally, I am permitted to give the following extract from a note from Mrs. Ellen H. Richards, whose excellent work in indus- trial and household chemistry is doubtless well known to you. I submitted the early types of my oven to an investigation which was conducted under her direction by Miss Marion Talbot, whose thoroughly scientific report upon the diffusion of heat and other matters encouraged me to go on, and was wholly consistent with my own experiments and with all the evidence which I have since obtained. This latter report is too long for inclusion in the present address. Mrs. Richards's present statement is as follows : It seems to me that the mission of the Oven and Cooker is in the ideal life of the twentieth century, as shown by Bellamy. That is, wben the people of the middle classes, as we know them now, shall pay attention to the question of food, OLD AND NEW METHODS IN ZOOLOGY. i9 and when the present kitchen and cook shall be abolished ; when in each section we can buy a chicken ready dressed for the oven, a fish all washed and stuffed ; when we can get bread and pastry such as we like; in short, when we have places like the Women's Exchange on Boylston Street, in each ward or village — then we shall use the Aladdin Oven, to dispense with kitchen and cook, but until then it will come into use only as an accessory, and especially in summer. Unskilled hands can get much better work out of it than out of an ordinary range, chiefly because it can not be overheated, and things can not be burned to a crisp. Our people need to learn what is to them a new art, the delicate flavoring which is brought out only by time — that is, by slow cooking. When a stew deliciously flavored is to people better than crisp beef, then the oven will go; but the majority of our people are still barbarians in taste, and it will not do to claim too much. I am sure that the conditions of slow cooking are very favorable to ease of digestion, and that the digestibility of many things is very much increased. I am sure that economy lies in the use of material which is much less expen- sive, but here again we must learn to like the result. In summer the saving of fuel is very great; in winter most people need the fire — often the kitchen is the only fire. Educated housekeepers with their own hands must work it up. Servants will not learn anything new unless working with the mistress. I believe the idea is destined to give a much-needed relief to multitudes of over- worked women, just as soon as they can be convinced of the possibility of relief. I may venture to subscribe myself, especially in this presence, by the use of the same words which I once adopted as a motto in my treatise on the " Missing Science of Cooking." I am — Coctor non Doctor. -+•+- OLD AND NEW METHODS IN ZOOLOGY. By M. H. de LACAZE DUTHIERS.* PERMIT me to begin my address by a reminiscence of the origin of this Association, which has haunted me from the moment when you did me the honor to make me your president. It was in July, 1871, when, as we were leaving the Academy of Sciences, Wurtz, taking me by the arm, in his friendly way, said : " Come to my house to-morrow evening ; I wish to talk with a few of my friends concerning a scheme which I should be very glad to see carried out." MM. Delaunay, Claude Bernard, Decaisne, and I met at Wurtz's house in the rue Saint-Guillaume on Tues- day evening, and held what we may call the first meeting of the Association. As the last survivor of the company I can not re- frain from recalling that intimate interview at which our Associa- * From the presidential address at the French Association for the Advancement of Science. 2o TEE POPULAR SCIENCE MONTHLY. tion was born. I can still see Wurtz, with, captivating animation and almost feverish activity, pacing the floor with precipitate steps and picturing to lis what he thought our society ought to be — and what it has become. He pointed out the priceless advan- tage to be derived from these meetings, to be held in all parts of France. "We shall," he said, "seek out modest local students living far from the center to meet us and make known the results of their investigations ; we shall draw the most timid of them into the scientific current, and shall thus be able to exalt our be- loved country in the eyes of the scientific world." Now, the only witness of that first and modest meeting, I believe that I am the interpreter of the feeling of you all in paying one more tribute to the memory of these our first and illustrious co-laborers. In addressing you I purpose to inquire what zoology was, what it is with some, and what it should be. The science of ani- mals of a hundred years ago and that of to-day resemble each other but little. Comparing them and seeking the cause of the great differences, we recognize a few leading facts which I have selected, and of which I will speak. In the former time, when so many reforms were in preparation, and when excited minds were looking for other objects on which to utilize their activ- ity than our sciences, always calm and independent of revolu- tions as they ought also to be of politics, natural history held but a small place in men's thoughts. In 1789 Linnaeus and Buffon had only recently died, and their names were still radiant with the splendor of their living brilliancy ; they dominated as abso- lute masters, and summarized in themselves all of zoology. Yet in their minds and works they resembled each other but little. Linnaeus, precise, methodical, a classifier first of all, brought order and clearness into the minutest details of the things of nature, and, as he proposed a concise and easy language, his influence be- came so preponderant that Haller complained of his tyranny. If the reform of the scientific language which Linnaeus worked out imposed itself with such force, it was because it answered to one of the needs of the moment. The simplicity, facility, and espe- cially the opportuneness of his nomenclature were the cause of its great success ; and it should be added that its value was so great that we have not yet sensibly departed from the rules on which it was founded. The opposite of Linnaeus, Buffon took pleasure in broadly drawn descriptions and pictures ; and, when he treated of general considerations, he animated them with a powerful inspiration. A profound thinker, regarding science from an elevated point of view, he engrosses and subjects us. Who among us does not rec- ollect the enthusiasm with which he has read some of the passages in the " Epochs of -Nature " ? By his reasoning and in the conse- OLD AND NEW METHODS IN ZOOLOGY. 21 quences of the observations which, he interpreted, Bnffon sought rather to foresee what should be or ought to be, than to fix what he ascertained. He was thus often in advance of his tirne, and the elevated considerations to which he gave himself were within the grasp of only a small number. Linnaeus, on the contrary, described, simply and clearly, what was. With such qualities these two men would often be far from agreeing ; and we might apply to them the distinction, which had not yet been expressed, between the school of facts and the school of reasoning. While Linnaeus and Buff on thus summarized in themselves all of zoology, although from different points of view, their labors lacked a basis the imperious need of which was universally felt. It was already beginning to be understood that the study of the habits, geograph- ical origin, and external characteristics of animals was not enough. At that moment Cuvier appeared. The reform which he intro- duced in zoology was very important, and his work, on the " Ani- mal Kingdom distributed according to its Organization/' produced a momentous impression. His great fame, like that of Linnaeus, is due to the fact that the modification he made in zoological studies corresponded to a certain want, and was a necessary re- form that came at the time when it was most needed. Zoologists of the classifying kind, who occupy themselves only with the ex- ternals of animals, have been compared to librarians who arrange their libraries according to the backs or covers of the books, with- out regard to what is within them. It was Cuvier's great merit that he saw clearly that to reach a truer knowledge of things we must not only be acquainted with the names and external feat- ures, but with the internal characteristics as well. To that end he introduced the anatomical idea into the history of animals. In doing it he rendered the greatest service to zoology ; and to this, too, must be attributed his great success, which was equaled only by that of Linnaeus, and also the great reputation in which French zoology shone at the beginning of the century. To-day, even those zoologists who criticise Cuvier the most, nevertheless follow his precepts. We can not apply the same standards of criticism to his work that we would insist upon in judging a work of to-day. To make an equitable estimate, we should put ourselves back to his time, and take account of the gaps in the knowledge of that period, and of the insufficiency of the means which observers could control. It will soon have been a hundred years since Cuvier's work was performed. In that time a great many discoveries have been made, and many conquests have been achieved to cast a new light on questions which were insoluble then. Zoology remained for a long time at the point to which Cuvier led it ; and we have to come to the middle of our century to see new ideas brooding and bringing about great modifications in the 22 THE POPULAR SCIENCE MONTHLY. direction of studies or in some of the branches of the biological sciences. I purpose to supply only a few examples of them. I recollect that in 1855, when I was a professor at Lille, Mr. Huxley wrote to me that " we in England are all stirred up and much per- plexed by the discoveries of M. Boucher de Perthes." The refer- ence is, of course, to the interest that was aroused about the cut flints of Saint-Acheul and the famous jaw-bone of Moulin-Quignon. English men of science and geologists came to Amiens, lively dis- cussions took place, a committee of Frenchmen and foreigners was formed and proceeded to the spot to make official investigations. Some fraud and incredulity were mingled in the affair. A work- man confessed to me, for a money consideration and a promise of silence, that he had himself fabricated one of the two specimens which I procured, and that it had not lain long enough in the bed to acquire the patina of the other. The point I desire to emphasize is, that the real thing that was discovered then, especially after the visit of the British investigators, was the books, the researches, and the new ideas of M. Boucher de Perthes, which had till then passed unnoticed. The beginning of the prehistoric studies, which have since attained so considerable development, may be dated from this time. Since the discoveries of Boucher de Perthes at Saint- Acheul, and those of Lartet and Christy in Pe'rigord, a part of the history of man has been completely transformed ; and geology, so far as concerns the most modern formations, has been subjected to the salutary influence of the new knowledge. What has become of the superannuated ideas that conceived fossil man impossible ? What new problems, full of interest, have been presented since the remains were found in Pe'rigord and other places of animals that no longer live where their bones are lying ! How many in- teresting questions have resulted from the simple discovery of a reindeer-horn in a grotto of Eyzies ; and what a long road we have gone over since then ! Is it strange that the number of explorers has become great, and that liberal and often magnifi- cent encouragement is given them ? It would be ungrateful in this connection not to repeat the acknowledgment of our obliga- tions to one of our members — M. Girard, of Lyon — who has be- queathed to our Association one hundred and seventy-two thou- sand francs to be applied exclusively to researches in prehistoric anthropology ; the proceeds of which your committee is able to use this year for the first time. The lively emotion produced by the discoveries of M. Boucher de Perthes had begun to subside, and researches were going on everywhere, when Darwin's first studies appeared in 1858 and 1859. These dates must always be memorable in the history of natural science, for they mark an epoch from which zoological studies entered upon a new course. The learned world, we might say, OLD AND NEW METHODS IN ZOOLOGY. 23 revolted when Darwin's book appeared. Then enthusiasm, with all its exaggerations, succeeded the first astonishment ; and in a little while, a reaction taking place, innumerable investigations were begun with an activity and a curiosity which the previously received ideas were no longer capable of determining. In the first spasm of enthusiasm the great naturalist's theory was called Dar- winism ; at a later period, dealing less in details and generalizing more, it was called Transformism. It must be recognized that whatever measure of confidence we put in transformism, whether we accept it in its whole extent and with all its consequences, exaggerate it, modify it, accept it with amendment, or reject it, no one can doubt that it has pro- voked a truly extraordinary scientific movement. Both partisans and detractors, in seeking for proofs in support of their opinion, whether demanding its secrets from embryogeny, or digging into the strata of the earth in order to interpret the remains of organ- ized beings which they inclose ; all, whatever may have been their method, ideas, opinions, or even hostility, have contributed greatly to the progress of zoology. Thus we are far from the period of Linnaeus, when the external character was everything; and from the period of Cuvier, when the anatomical idea and the study of the exterior were the only guides of the classifier. Now we inves- tigate the connections of beings by going back from the existing to the primitive forms, or vice versa. We try to explain the varied forms under our eyes by the aid of the laws so happily formulated by Darwin. Evolution is encountered everywhere. Whether one be a transformist or not, he must bow and acknowl- edge the force of the tremendous bound which the impulse given by Darwin has caused. There are, however, as Claparede has said, " terrible children " of transformism who are more anxious to make a noise around their name than to discover the truth. We must prudently dis- tinguish from them the conscientious students who seek long, scrupulously, and painfully for precise facts in order to deduce from them consequences that will support their theories. These surely advance science, while the others often compromise it. The one thing to oppose to exaggeration, assumption, and enthusiasm is experiment. It is as mandatory to-day as in the preceding period were the reforms which I have mentioned. While Darwin had an immense and legitimate success, the ideas of Lamarck, who more than half a century before him taught and published the same views on the mutability of species, were long forgotten. Our illustrious compatriot has been treated rather unjustly and severely. There are whole pages in the works of Lamarck containing the theory of transformation completely developed, to which Darwin has added nothing except to confirm 24 THE POPULAR SCIENCE MONTHLY. tliem. The minds of zoologists were not prepared in his time to receive his ideas, and he had not the happy faculty of hitting upon that clear and precise method of statement that imposes itself and makes itself accepted by all. For a reformer to secure a following, his idea should be defined with dazzling clearness and precision, and achieve mastery by virtue of its seductive force. Darwin's exposition of the universal and constant strug- gle for existence, ending in the selection and survival of the vic- tor, was so true and clear as to lead all readers into accord with it. Cuvier, they said, could reconstruct the whole of an extinct animal from a single bone. The thought spoke to the imagination of the masses ; and when he laid down the principle that in an organism, as in an equation, the known terms may be made to give an unknown one, he commanded the admiration of a whole gen- eration. Linnseus, who at a stroke reached the reform science was aspiring after, to rid itself of nonsense in nomenclature, and who found names to fit the occasion, became the tyrant of natural history. It was not possible for Lamarck to realize a similar success ; and a comparison of his arguments with those which Darwin brings in support of the doctrine of changes in the forms of animals, and a reference to the epoch in which he wrote, will show why his ideas had to wait for the revelations of the English naturalist before they could be recovered from oblivion. In view of the surprising discoveries to which the continuous study of the evolution of the lower animals has led, and of the direction of zoology under the influence of transf ormism into new ways, it is impossible not to recognize that experiment alone ful- fills the requirements of the moment. It is only through experi- ment that the great questions of natural philosophy can be an- swered ; that the discussions raised by clashing convictions, haz- ardous assertions, so-called philosophical doctrines, and venture- some syntheses too often lacking substantial bases, can be justly appreciated or solidly established. The citation of a few instances will illustrate this assertion. Every one has noticed the gall-nuts on oak-trees, excrescent tumors produced by parasitical insects — the Cynips — which lay their eggs in the mother plant by the aid of a gimlet - shaped ovipositor. The young insect finds within this swelling all that it needs to sup- port life, and quietly in it reaches complete development ; and it can easily be caught as it issues from its prison. Entomologists have catalogued a large number of species and genera belonging to the family. In doing thus, they have followed pure and de- scriptive zoology, as it was in the times of Linnaeus and Cuvier. Now, it has been found, after watching the evolution of these parasites, that all the genera and species have to be revised. Thus, for example, we find on the superficial roots of an oak-tree galls OLD AND NEW METHODS IN ZOOLOGY. 25 of varied colors and sizes, the insects issuing from which are wing- less. When the trial is made, they will be found incapable of reproducing the warts they came from ; they are, besides, all fe- males. Again, we may see, in the spring, the ends of the limbs of the same oak bearing greenish-red tumors, which naturalists have long called oak-apples. They are also galls from which Cynips issue; these too, like the others, are incapable of reproducing the swellings from which they came ; but they have wings, and are both male and female. Here, then, are beings totally different, if we study them separately as they come out from their nests. Now let us follow the experimenter, first observing that the insect of the root has been called Biorhiza, and that of the apple Texas. The Biorhizas escape from the roots on which they are hatched, and raise themselves up slowly and painfully, having no wings, to the ends of the branches of the tree. There they lay unfer- tilized eggs, and cause, by piercing the twigs, the oak-apples from which the Teras issue. On the other side, the Teras, escaping from their apjjle, copulate, and the fertilized female descends to deposit her eggs in the roots. The Biorhizas, therefore, are hatched from the eggs of the Teras, and the Teras from the eggs of the Biorhizas. Here, then, are two genera wholly distinct in habits, organization, and external characters, which are neverthe- less derived each from the other, and which zoologically ought to form only one. How could M. Adler have discovered these facts, except by experiment ? When we remark that the Cynips are relatively high in the animal scale, we are justified in believing that a very great number of similar surprising facts may yet be found among lower forms. I can not refrain from relating another life-history which is almost a romance. There is a hard sandstone in Provence, inter- spersed with friable strata, in which burrowing insects construct their chambers. A kind of bee, the Anthophorus, makes nests there and fills them with honey, on which it leaves its egg to float ; then, finally, plasters up its chamber. Instead of Anthophores, entirely different insects come out from these nests — Sitaris, be- longing to a group very remote from the bees. Let us see how they manage to substitute themselves for the legitimate proprietor of the nest. In the autumn the impregnated female of the Sitaris deposits her eggs in front of the sealed galleries of the Anthopho- rus. The young are hatched from these eggs, and lie in front of the closed doors, and thus remain in a mass, mingled with the dust and rubbish of the place, through the winter. In the spring, such of the bees as have reached their term come out from their prison. These earliest insects are all males ; but, though preco- cious in being hatched, they are still tender to the changes of the weather, and remain half frozen and torpid in the dust along with 26 THE POPULAR SCIENCE MONTHLY. the young of the Sitaris. The time has come for the last to be- gin to act. They have been called Triongulins by Ldon Pufour, from the claws with which they are armed, and by which they at- tach themselves to the bodies of the Anthophores waiting for the next stage in the conditions that favor their development. With fine weather the female Anthophores come out and carry on their work of burrowing and storing up honey till the time of fecunda- tion arrives. Then the Triongulin changes its quarters from the body of the male to that of the female, where it remains on the watch for the laying of the egg, when it transfers itself to that, and with it enters the honey-chamber. With it it is shut up when the Anthophorus closes the door of the chamber for another season. The Triongulin will not eat the honey, for it is sure death to it by drowning if it touches it. It floats on the egg and feeds upon it ; when it has used up its ration, it changes its shape, as well as its habits and taste. It is as eager now for the honey as it was to keep away from it, and grows upon it till it goes through another change and becomes the Sitaris which we observe coming out from the chambers of the Anthophorus. Three years of assid- uous studies and investigation were required to obtain this curi- ous life-history. Contrast now the results obtained by Leon Du- four, an entomologist and naturalist of the school of Cuvier, with those which M. Fabre has reached by experiment. I could also show you examples of an excessive socialism in so- cieties of animals, even passing the limits of what has been con- ceived for men ; comprising individuals whose parts are assigned with the greatest precision, some working to feed the collectivity, eating and digesting for all, others possessing the single function of reproduction of the species ; and still others serving as beasts of burden for the rest ; and looking a little further, we might occa- sionally discover idlers at rest while their fellows are working to feed them. Take the lobster which we fish from among the rocks and on the sea-coast. In the earlier part of its life, it swims at large on the surface of the fresh water. Its plump and fleshy body, so sought for as a food, is represented then by a broad and extremely thin plate, so peculiar that the zoologists of the old schools made it not only a genus, but one of the types of a group very remote from its fellows. What would be the difference be- tween these zoologists and one who should regard the child and the adult of a savage man seen for the first time on some un- known island as forming two genera ? Is it not evident that in the times of Linnaeus and Cuvier, when they examined animals at only one moment of their existence, naturalists could not follow the filiation of facts which evolution alone reveals to us ? The discovery of the Triongulin and the Biorhiza, made when species were defined only according to characteristics falling under the THE DECADENCE OF FARMING. 27 senses, the surprising transformations of which had not been shown us by their evolution, could not possibly have informed us of the true significance of those beings. I know very well that the quality of an experimental science which I claim for zoology is not accorded to us by all students. Those who withhold this recognition are specialists who judge of our science by what they learned of it when they were pursuing their general studies, and when it consisted chiefly of learning names and registering characteristics. They still think it a sci- ence of words and memorizing. But we are happily able to re- flect that while they have followed and pushed on the science in which they have become masters, they have concerned themselves but little with the advance of the other branches which they have not cultivated ; and their present judgment is based on the con- dition of the science a half-century ago. I think it can be estab- lished without contradiction that there is not a zoologist of the present day, unless he be over-rash or ambitious to enjoy the dis- covery of a new species, who will venture to affirm that he is ac- quainted with any being before he has followed its evolution. To follow the evolution, experiments must be instituted, and that con- stitutes experimental zoology. Because our science is now in a critical condition, it is most positively affirmed by the partisans of the transformist theories that it should modify its methods of in- vestigation, and besides registering species should submit unre- servedly to experimental control. Such is the conclusion which we logically reach, and which imposes itself upon us to-day. — Translated and abridged for the Popular Science Monthly from the Revue Scientifique. ♦*« • THE DECADENCE OF FARMING. By JOEL BENTON. SOME years ago the editor of a prominent journal sent me a slip containing a column and a half of advertisements of farms for sale, cut from a Boston daily paper. The farms offered were located in New England, where the supposed benign effect of the national Government's attempt to " diversify industry," so that farming need not be overdone, has had its supreme chance. These farms were not poor or worn out. They were in the midst of our best social culture, as developed by our most intelligent rural communities. Upon them were improvements and, in the main, good buildings. Railroads ran over or near every one of them ; large factories and populous towns were near, to buy their products ; schools and churches were visible, almost from their door-steps and gateways ; beauty was in the landscape, and health 28 THE POPULAR SCIENCE MONTHLY. in the very air. Whatever the best civilization has to offer, out- side of great cities or large towns, was accessible to the homes they represented. If anywhere on the planet human beings could be happy and prosperous, in beautiful homes, it should have been there. But the farms were for sale, nevertheless ; and, though this was fifteen years and more ago, some of them are for sale still. The column and a half of advertisements was only a sample of a hundred other columns of advertisements of a similar sort pub- lished in other New England papers ; and the offers to sell still go on. The clipping sent to me, as symptomatic of a great move- ment, came from the office of a famous protectionist daily, and was sent in order that I might make some appropriate comment upon the situation, or give some advice which should be apt or remedial in relation to it. This was done at a period, however, when there was no ques- tion of taxation or political economy uppermost in the public mind. No suspicion, even, was entertained that legislation of any sort was involved in the problem presented, or that any other than a hortative appeal to boys to stick to the farm, or some sug- gestion as to better modes of farming, was needed. It is now twenty years, at least, that farming has been going rapidly downward. Farms bought in the war era have been sell- ing almost everywhere in the East for from one half to one third of their cost. Farms in New England, and some in the Middle States, are frequently sold for less than the buildings cost which are upon them. This is really no exaggeration. Sales of this sort, and where the depreciation in value has wiped out the own- er's equity in them, have been for years a matter of notorious knowledge in almost every Eastern community. Within a year, in a healthy and fertile county not sixty miles from New York city, a farm having on it two mortgages — a first mortgage of three thousand dollars and a second mortgage of two thousand — was sold, under foreclosure, for the sum represented by the first mortgage only. The holder of the second one did not think it worth while to be present, or to have a representative present, at the sale, to bid the single dollar which would have saved or made a show of saving his investment. Very recently the New York State assessors have issued a report containing some results of what they have discovered so far as they have gone, in respect to the assessed valuations of farm lands in the various counties. And this is their story : " In fourteen counties visited they found that farming lands had de- preciated in value, while city property had increased in value." State Assessor Wood is of the opinion that " in a few decades there will be few or none but tenant farmers in this State. Year THE DECADENCE OF FARMING. 29 by year the value of farm, lands depreciates." There is not the slightest reason to believe that there is a county in this State of which a better report can be made. The fourteen examined may well stand for all. Following closely on this report for New York comes the report of the Bureau of Labor Statistics for Illinois, in reference to farm-mortgage indebtedness. This gives a summary of this indebtedness at the following periods, viz., in 1870, 1880, and 1887 ; and evidence is also given as to the actual value of farming lands in the State. By leaving out town and city lots, and the suburban district of Chicago, the purely agricultural part of this debt is seen. And it is given as follows : Tear. Debt. 1870 $95,721,003 1SS0 103,525,237 1887 123,733,098 The report tells its own story ; for farms are a constant quan- tity and do not increase. It is only the wave of debt that increases over them. As this report separates, with such accuracy as it can command, " mortgages representing deferred payments of purchase money from loans," the deduction of the commissioners is, that " the mortgage indebtedness cf farmers for borrowed money has increased twenty-three per cent since 1880 in Illinois, and that this is more than twice the increase in the value of the farm lands. An increase in land values is reported in twenty- five counties, a decrease in twenty counties, while in sixteen coun- ties the values have remained unchanged." This is far from a pleasant showing for a State so naturally good as Illinois, and one which was so recently a new and almost a frontier Commonwealth. But you may go farther West and find figures of the same solemn sort. In the Western States the farm mortgages amount to three billion four hundred and twenty-two million dollars. This is equivalent to a debt of two hundred dol- lars per capita for each person, or one thousand dollars to each head of a family. The interest which these mortgages pay runs from seven to nine per cent, while the profit on the farm capital, to put it large, is only from four to five per cent. But, take up any newspaper or magazine, and read its adver- tising columns in respect to loans. What are they which are most popular and extensively advertised ? Why, they are " farm investment loans." " Sixteen years' experience without loss of a dollar." And the interest is delivered at your door almost. These siphons are now extending far beyond the Mississippi and Mis- souri, on the virgin soil of the continent. For a while they can be borne there, where the capitalization in a farm is either slight or nothing, and where the money borrowed is mainly for buildings 3o THE POPULAR SCIENCE MONTHLY. and improvements. But it can not be long, without a change of proprietors, the original ones dropping their title, and giving up the struggle to other lists of unfortunates. There is no doubt but that the investments in these vampiric mortgages are good — that is, good for those who loan the money, and good also for those roving or stationary agents who make their commissions out of them, and who scour every Eastern town where money is to be had to put into this form of security. I am not blaming these negotiators. The money must be bor- rowed, and somebody must furnish it. But is it not pitiful that the one business in this world which seems nearest to man's primi- tive nature, without which no other could exist, and into which the moralist and the well-wisher of his species is ever ready to advise young men to go, should be the selected prey of the most destructive and cruel legislation that can be invented by the wit of man ? All over the statute-book, if there is a law made having any effect at all upon the farmer, it is with an almost malicious cer- tainty— one might think, if he judged by its effects — made to operate against him. Is it a half -holiday, or several whole ones, that are enacted ? The operation of them is not a help to, but is a draught against, the farmer. His cows and his crops, and Nature itself, to whose laws he is more than anybody else tied down, will not and can not accept their supposed advantage. His work must still go on ; and these are only new stumbling-blocks in his way, which leave him shorn of his hired help, to pursue his tasks without the customary assistance. If an eight-hour law is enact- ed, its maleficence, not its advantage, falls on him. The milking- hour and the harvest will not be postponed in obedience to any legislature. So far as it makes the day's labor brief, so certainly it extends his own labor from twelve hours to fourteen. Notice, too, how every tax system now uppermost puts the heavy end of its incidence on the farmer. In the State, county, and township allotment of fiscal burdens the tax is direct. It falls upon what can be seen and discovered with greatest weight. But it never fails to discover the farmer. His broad acres can not be hidden or sworn away ; while his neighbor, rich in per- sonal holdings, can cunningly suspend his own tax by evasion — and sometimes by an artful change or confusion of residence — so as to add his tax, too, to the tax of the beridden farmer. But worse than all this is his relation to the national tax system, which exploits away his hard-earned profits, small in percentage, almost invisibly, and then adds abuse to injury by successfully persuading him that it exists for his supreme advan- tage. He pays for a paper, as likely as not, which tells him, and has been telling him for a generation or more, that the beneficent sys- THE DECADENCE OF FARMING. 31 tern which prevents him from, buying forty-five hundred articles as cheaply as he might, and compels him to sell his own products, minute in number, at the lowest price which ingenious legal arti- fice can dictate, is a measure for his particular benefit. If he has read a paper which denies this, the doctrine is so new to this generation that he has not yet mastered it ; and he is apt to treat it with conservative inattention, or as a delusive suggestion, an investment in which must be set down for the present as one to be treated with as much caution as he would exercise in accepting an unheard-of and revolutionary scheme for working his farm. The siren charm with which the word " protection " asphyx- iates him has only casually, as yet, lost for him its sorcery. He is apt to have confidence in some regular order of things, such as the seasons, the sunrise, and the sunset ; and to him " protection " is, and has been, through long experience, as stable a factor in affairs as the precession of the equinoxes or the laws of the solar system. But, if he is ever to rescue his business and make it decently profitable, he must awaken from this long swoon. He must see and know that taxation of this sort is death to him ; and is fast making it impossible for an intelligent American to live and raise a family with the decent comforts of life on the best farm in the New England and Middle States. Very rapidly, in New England, the farms are passing into the hands of the foreigner, or distinctly peasant element, a class which reduces the necessities of life to the simplest scale, and which is able to do farming within the fam- ily, and so can eliminate the costly feature of hired labor. The question has been asked for years, " How shall we keep our boys on the farm ? " But it has never been answered successfully, and never can be. We ought to be profoundly thankful, considering what the farm now is as a business, that we can not keep them there. It is the best possible evidence attainable of the bright wit and level-headedness of the boys that they wish to work where gain is assured at the end of their toil. I may be told, very likely, that I have skipped one feature of the tariff, the one on wool, which was devised especially for the farmer's profit. But it was not ; and, if it had been, it has hurt him instead of helping him. It was devised by men who are either commercial men, or whose predominant interest is commercial rather than agricultural. These men constitute what is known as the Wool-Growers' Association. I think its important factor is made up of middle-men, or salesmen who traffic in the wool product. But, be that as it may, the duty on avooI has simply handicapped the manufacturers of woolen fabrics ; and by shut- ting out kinds of wool which we can not raise here, and which the woolen manufacturers must have to mix with native wools, has 32 THE POPULAR SCIENCE MONTHLY. actually lessened the demand for native wool, with the effect to lower its price. Apart from this, it is a notorious fact that the price of wool does not ever bear the relation it ought to, on pro- tection theories, to the rate of the duty. I once traveled with a wool-buyer, years ago, when a lower tariff than the present one prevailed, when he bought wool of the farmers, to speculate on, and gave one dollar a pound for it, which was the market price. Does any wool-farmer expect to get over half that now ? A very intelligent farmer, on whose hundreds of acres the wool product has been a feature for sixty or seventy years — a man who holds general " protective " opinions — told me frankly that the tariff, touching wool, gave no enhancement of price. He confessed that he had got very high prices for wool under a low tariff, and very low prices under a high one. As this wool-bribe is a menace to direct and equal laws, and is the price offered the farmers for support of legislation abso- lutely hostile to them, suppose we look a little further on its effects. Here are some facts for farmers to think over. Twenty-one years ago there were thirty-eight million sheep in this country east of the Mississippi River. "We have " protected " them all this time, and there ought fairly to be now, under a decent ratio of growth, at least fifty million. Are there this number ? On the contrary, there are now only eighteen million one hundred thousand. And they and the wool itself have greatly declined in price. It is said that, since 1875, there has been an increase in the number of sheep of about thirty per cent. But this is accounted for by the exten- sion of farms in our new Territories. The large flocks there are chiefly owned by aliens or absentees, and even these flocks, with their peculiar local advantages, are declining in value. Not a fraction of this increase in number can be due to the tariff, and no benefit comes from it to the growers of wool in the older States. To supplement these facts properly, read the following answers to questions propounded by the " Massachusetts United Questions Club," given by ex-Congressman John E. Russell : Question 4 is as follows: "Does the tax on foreign wool imported put the price of that up so much that, although the price of American wool is lower than it ever was hefore, yet our domestic woolen manufacturers are put at a great dis- advantage with foreign manufacturers, so that we can not make goods at so low a cost or of so good a quality, except such kinds of goods as can he made wholly of domestic wool?" Mr. Eussell replies that the specific duties on woolen cloths and flannels put the American manufacturer of fine goods at a sad disadvantage, confining him to the home market, and that the high price he is compelled to charge for goods narrows and restricts his market. Mr. Russell continues: "Makers of the fine flannels that are sold in competition with the best English and French goods import South American wool that has been sent to France and there cleansed of dirt and burs, and scoured. The duty on this wool is thirty cents a pound. There is no wool raised in this country that will answer the same pur- THE DECADENCE OF FARMING. 33 pose. It is the result of a soil and climate different from ours. It goes to France because, though France is a protected country, they do not think it economy to tax the raw material of manufacturing, and they consider it wise to so draw the line of protection as to preserve commerce with nations producing raw material. They exchange goods for wool, they make the freights, commissions, and profits of shipping, and we pay them for manipulation of the wool." " Question 5. — If the effect of the tax on foreign wool has been to put down the price of domestic wool and to put up the cost of woolen goods, who gets any benefit from it? Is it the farmer, who gets less for his wool and pays more for his clothing?" " Answer. — The benefit of this tax accrues to the politicians and to other enor- mously protected interests. The tariff on wool is the key-stone of the wide arch of protection, because it binds the farmer to the support of the whole system. Without his support the tariff would be reduced to a tax that would raise only what is required by the Government economically administered, with incidental protection. How the farmer is deceived may be further explained by a calcula- tion of what he gets even if he makes all that is promised him. The duty upon unwashed wool that comes in competition with ours is ten cents a pound, the average number of sheep in a flock upon the older Western farms is not over thirty, and the average product of wool on such a farm would be about one hun- dred and eighty pounds. If the duty increased the price of this wool ten cents a pound, it would be but eighteen dollars to each flock, or less than the enhanced cost of the clothes of his family. It gives him nothing to pay the increased cost of lumber, salt, tin, crockery, implements, fence-wire, etc. The fact is, that his protection fails to protect, and he gets nothing but the privilege of carrying the load. He is a victim of those who cut straps out of the hides of the poor to make stirrup-leathers for the rich." The next question of importance is number 9. It is as follows : " Is not the farmer misled when, under pretense of protection to wool, the price of his wool is reduced and the export of his wheat and cotton is partly stopped, because by way of a tax on foreign wool we prevent in part an exchange of wheat, cotton, and flour for wool? Answer: 'Misled' is a weak term to use under the circum- stances. We might say he is in the same position as the man who votes for high taxes to keep up his wages ! " If there is any farmer in the land who can read these undeni- able facts, and, after doing so, is still willing the " wool " shall be " pulled over his eyes," he, at least, deserves little pity for his fate. Sheep ought really to be a profit to the farmer, as they are an im- portant factor in soil enrichment. They ought not to be unprofit- able if they grew hair in place of wool. But our law-makers have doomed them. The only " protection " they ever were in need of is protection from dogs and tariff -mongers. There is really no probability that we can ever have a " farm- protecting" tariff, for obvious reasons. One is, the farmers are too numerous to organize efficiently. They lack the massed capi- tal and commercial skill necessary to maintain a lobby at Wash- ington. They are too vast and minutely divided a body to be thrown into any efficient cohesion. To move Congress and com- pel politicians, you want just the sort of conspiracy that exists and VOL. XXXVI. 3 34 THE POPULAR SCIENCE MONTHLY. V is upheld by the tariff barons and beneficiaries — a comparatively few very wealthy corporations, each one " log-rolling " with the other for mutual benefits. By their employment of large bodies of workmen, and their power to contribute money and to bull- doze morally through the " pay-envelope," congressional districts, States, and the nation are in their clutch. Of course, the farmer vote is great enough to have its way, but it can not apply itself with the force and ease of a well-regulated machine, as its almost feudal masters can theirs. Our farmers lack also, as I have already said, the clear perception that they and their interests are exploited. The system which robs them, under cover of law, large numbers of them still believe is for their own benefit. It is a matter for amazement, though, that some leaders among them do not, at least, plead through their granges and societies, for direct protection, since they are so sure the complex taxation of themselves tends to their prosperity, by some indirect hocus pocus which nobody can explain. If protection is good for agriculture, it would certainly help it more to put it in the line of direct bene- fit, and let other industries, so long pampered, have for a change the indirect blessings of the tariff for a term of years. As the farmers are by far the most numerous single part of our population, and represent well toward one third of the people in numbers, why not give to them directly, lavish bounties from the national treasury ? Let an act, for instance, be passed to give them from fifty to one hundred and fifty per cent more for all they raise than they now receive. This would somewhere near double their income. "With this great enlargement of their means they could pay more for labor, and they could buy two or three times as large a quantity of manufactured goods. Of course, " could " invariably means " would " in the protectionist's diction- ary ; and so we should see a tremendous impetus given to all other industries, and to manufactures particularly, by the very greatly increased purchases of the farmers and their doubly paid help. As it has been for two or more generations, " the few " have been protected on purpose to help " the many " by the tremendous over- flow which the benevolence of " the few " precipitates. But just think how much more overflow would be sure to run from " the many " to " the few " than is possible in the other direction ! Could there be any finer or fairer scheme than this ? Having lived in the moonlight of protection so long, is it not the farmer's turn now to have its sunlight ? And, inasmuch as the manufact- urers and protected interests say that this moonlight, or indirect incidence of their tax system, is a great good to the farmer, it will, of course, be of great good to the manufacturer. And there will be vastly more of it, since large bodies reflect immensely more to THE DECADENCE OF FARMING. 35 small ones than small ones do to large ones. Or are the protected interests really afraid to take their own prescription ? We suspect they would be, and, in fact, could not be hired to take it. But it is the impending truth — which will some day, and I think very soon, filter into the farmer's mind — that alone can save him. When he sees that he, and he most of all, is bled for others, and for their private gain, he will cease to believe in enforced phle- botomy. When he finds out that the word " protective," so far as he is concerned, is an abominable misnomer, and should be trans- lated " destructive," there will be heard a voice from the farms that will give the system so long delusively described its death- blow. Years ago the farmer's boy, when he went to school, was taught that the business of the United States consisted of " agri- culture, manufactures, and commerce." It has long since ceased to be an equal tri-division. Agriculture and commerce, as they once were, are things of the past. The one has been made un- profitable beyond description ; the other is now impossible, except in a reduced way, under an alien flag. Ship-building is " protected " to death, and the American money that goes toward having it done abroad simply builds ships that, in case of a war, can be turned against our own shores and our depleted navy. But we have — as trophies of our absurd Chinese system — manufactures (none too flourishing, if the men engaged in them know) and a " protective " tariff. The long endurance of the superstition on which " protection " is based has had two bulwarks — the necessity for revenues ex- traordinary, and the power of money, contributed by directly in- terested parties. An economically administered government should break down the first, and the force of facts the second. As we hold in derision now the discovery of the philosopher's stone and perpetual motion, so future generations will look upon this fetich of our time, and not without unspeakable amazement. They will see a generation here and now that is trying to lift itself over the fence by standing in a corn-basket and pulling upward on the handles. The wonder will not be so much that they tried, as it will be that for so long a time they supposed they were suc- cessfully performing this impossible feat. The history of the genus Platanus, which includes the Oriental plane-tree and our sycamore, has been traced by Lester F. Ward back to the Tertiary period, when there were at least twenty species, mostly American or arctic. The genus and the entire type to which it belongs seem therefore to have been American ; and its numerous and strange archaic forms "not only formed the umbrageous forests on the shores of the great inland Laramie Sea where the Rocky Mountains now stand, but also those of the ocean at a time when it still pushed its arms northward across what are now the great plains of Texas, Colorado, and Wyoming.'1" 36 THE POPULAR SCIENCE MONTHLY. SENSITIVE FLAMES AND SOUND-SHADOWS. By W. LE CONTE STEVENS, PROFESSOR OF PHYSICS IN THE PACKER COLLEGIATE INSTITUTE. THE conception that sound is due to wave-motion in an elastic material medium was first distinctly expressed in the six- teenth century by Lord Bacon. He distinguished between local motion in a medium and the propagation of this motion through it, referring to the transmission of sound through both air and water by way of illustration. For measuring the velocity of sound in air he proposed a plan which has been repeatedly applied since his time, that of firing a cannon and noting the interval be- tween the flash and the report as heard at a measured distance. It is impossible now to determine how far these observations may have been original with Bacon, or to what extent they may have expressed the current knowledge of his time. They were clearly apprehended by Galileo, who discovered the law of simple harmonic motion and made the first well-authenticated experi- ments on the relation between vibration frequency and musical pitch. But it is to Sir Isaac Newton that we must give the credit of first applying the wave theory rigorously to the phenomena of sound. Assuming this theory, he showed the possibility of calcu- lating what ought to be the velocity of propagation through any medium of known elasticity. He deduced a formula which has been found applicable to most media. In the case of atmospheric air it failed, but because it required a correction dependent on certain laws of heat which had not then become known. The correction was made by Laplace, and the formula, as thus completed, is now found to be applicable to all known gases. This was only one of the many important principles established on a mathematical basis in the " Principia," and published in 1687. Even before this date, the conception that light, as well as sound, might be due to wave-motion seems to have been grasped by a few thinkers. In 1665 a book on " Light and Color " was pub- lished at Bologna, two years after the death of its author, Fran- cesca Maria Grimaldi, a Jesuit priest and astronomer. In this he recounts some interesting experiments, which did not, it is true, lead him to the wave theory of light, but served as the basis on which this theory was subsequently established. Similar experi- ments were made soon afterward by Robert Hooke, the ever- jealous rival of Newton, and by Christian Huygens, their distin- guished Dutch contemporary. Huygens demonstrated that, if an impulse be given to any single particle in a uniformly elastic ma- terial medium, it must be propagated thence as wave-motion SENSITIVE FLAMES AND SOUND-SHADOWS. 37 equally in all directions ; and that the propagation of a wave front in any given direction is the result of a multitude of interferences among the elementary waves started from the particles which are successively disturbed. Accepting this principle, the laws of reflection and refraction, whether of light or sound, follow imme- diately ; and they were worked out with great skill by Huygens. Another consequence is, that if an obstacle be interposed in the path of a wave, its edges must serve as new centers around which secondary waves will be propagated, while the main wave con- tinues to advance. This is familiar in the case of water-waves. If, therefore, light be due to wave-motion, no perfect geo- metric shadow is possible, for the shadow must suffer encroach- ment from these secondary waves thus diffracted. Such phenom- ena were actually observed in the case of light by Grimaldi, Hooke, and Huygens, but no satisfactory explanation was then given. It is surprising that Huygens did not think of applying the theory which had been so satisfactory in its application to other optical phenomena. He had not attempted to measure the length of waves of light, and had no conception of their exceeding minuteness. If any diffraction phenomena were to be observed, the encroachment for which he naturally looked was far greater than what had been noticed as inexplicable and almost impercept- ibly narrow fringes. The absence of the diffraction phenomena such as he may have expected did not cause him to abandon his wave theory, though he could not but perceive that it constituted a stumbling-block. To the mind of Newton this obstacle was in- superable ; it determined his rejection of Huygens's theory. If Newton was not the inventor of the emission theory of light, he was certainly its most ardent advocate. It came into promi- nence along with the wave theory, or indeed a little after this ; and by means of it very satisfactory explanations could be given of most optical phenomena. Newton's reasoning, and the author- ity of his great name, caused its acceptance by all contemporary physicists, except Hooke, Huygens, and Euler, and by all his suc- cessors for a century. Whichever of the two theories is accepted, assumptions are involved which are open to attack and incapable of being substantiated on any antecedent grounds. Its value has to be measured alone by its consistency with observed facts. It was not until about the beginning of the present century that Dr. Thomas Young revived the long-discarded wave theory, explained the diffraction of light by its aid, and showed the incompetency of the emission theory. His views were at first generally rejected, but in time they attracted the attention of Arago and Fresnel. The latter especially entered into the investigation with enthusiasm^ and completed the establishment of the wave theory upon founda- tions that have never since been successfully assailed. The elastic 3 8 THE POPULAR SCIENCE MONTHLY. medium required for the propagation of light-waves, whether through interplanetary space or terrestrial bodies, is the universal ether, of whose existence we have no evidence except that, by as- suming it and applying mathematics, the results of computation are exactly corroborated by observation and experiment. The elastic medium required for sound-waves may be solid, liquid, or gaseous. In any case it must be material. Assuming, then, an obstacle in the path of a wave of sound or light, a shadow should be produced ; but since the edges are sources of secondary waves, according to Huygens's principle, these should encroach upon the shadow. The degree of encroach- ment can be expressed in a mathematical formula, and is thus shown to be proportional to the wave-length. The average length of a wave of green light is now known to be about s 0 1 0 0 of an inch. The encroachment on the geometric shadow is hence so small that refined methods are needed to make it perceptible. In the case of audible sound, on the contrary, when propagated through air, the wave-length is ordinarily so great that the en- croachment almost wholly masks the presence of any shadow whatever. For the pitch C, 132 vibrations per second, such as is often used by men in conversation, the wave-length is readily cal- culated, if we know the velocity of sound in air. Taking this as 1,120 feet per second, there will be 132 waves strung out over this distance in each second. The length of each is hence eight feet and six inches, or more than five million times as great as that of the average wave of light. For such waves it is hopeless to attempt producing any well-defined shadows. One of the most familiar facts in physics is that the pitch of a note becomes higher, and hence its wave shorter, in proportion to the increase of vibration frequency. If well-defined sound-shad- ows are possible, we must resort to sounds of very short wave- length. If the sound is continuous instead of explosive, this short- ness implies very high pitch. There are mechanical difficulties to contend with which make it hard to give much intensity to very acute sounds. The range of audition, moreover, is limited. For persons of good ear the range may be roughly stated as from 25 to 25,000 vibrations per second for sounds of small intensity ; indeed, many fail to perceive any pitch exceeding 15,000. To exhibit sound-shadows, therefore, it becomes necessary either to employ a source that sends forth sounds of such high pitch as to be inaudible to most of those who are expected to perceive the shadow, or to resort to a momentary sound of great intensity and short wave-length. Every one has noticed the decrease in intensity of the sound of a distant railway-train as it passes into a cutting. The observer is in a shadow which is incomplete but nevertheless noticeable. SENSITIVE FLAMES AND SOUND-SHADOWS. 39 The secondary waves, which are started at the upper edges of the cutting, reach the ear and give still a good idea of the character of the noise and position of the train. The range of the ear greatly exceeds that of the eye, not only in relation to the variety of wave- lengths by which it may be impressed, but yet more as to varia- tions of intensity. Just as sunshine and shadow during the day indicate merely variations in illumination without the complete extinction of light, so noise and sound-shadow are merely relative terms, the latter not necessarily implying the complete extinction of sound ; for in air diffraction usually plays so important a part as to forbid complete extinction, and to prevent all sharpness of definition at the edges of the shadow. When the medium is water instead of air, some new phenomena are noticeable. In 1826 Daniel Colladon's classic experiments on the velocity of sound in water were performed on the Lake of Ge- neva. The source of sound was a large bell, from which vibra- tions were conducted through the water several miles away to an elastic membrane stretched across the expanded opening of a par- tially submerged hearing-trumpet. They were thus given to the air within the trumpet and conveyed to an ear applied at its smaller end above the water. A bell when struck sends forth a vari- ety of tones, and it is often hard to determine which of these is most prominent. Usually that of deepest pitch is the slowest to die away in air, and often it penetrates to the greatest distance. Colladon made the remarkable observation that in water the low- er tones are conducted off to but a short distance before their energy ceases to produce the sensation of sound ; while the initial stroke is propagated much further, and is then perceived as a short, sharp, almost clicking sound, without definite musical char- acter. Placing the hearing-trumpet behind a wall which project- ed out into the water, the decrease of intensity was much greater than under similar conditions in air, and the demarkation of the region of shadow was decidedly more noticeable. Still more interesting than the experiments of Colladon were those made in the Bay of San Francisco in 1874 by Prof. John Le Conte and his son, Mr. Julian Le Conte. The source of sound was not such as would give a definite pitch, like a bell, but the quick, violent, single impulse due to the explosion of dynamite employed in the blasting of rocks which obstructed the channels. The intensity of the shock thus propagated was such as to be felt as a blow on the feet of a person seated in a boat three hundred feet or more from the detonating cartridge, and to kill hundreds of fish. Several vertical posts or piles, each about a foot in diame- ter, projected from the ground out of the water in the neighbor- hood. A stout glass bottle was suspended in the water about a foot in the rear of one of these piles (Fig. 1), within the geomet- 40 THE POPULAR SCIENCE MONTHLY. ric shadow determined by lines supposed to be drawn from the cartridge forty feet horizontally away. The bottle was perfectly protected from the shock of the explosion. It was then put in front of the pile. The first shock shivered it into hundreds of fragments. Other bottles, some filled with air and some with SA/VO STONE REEF ' M Fig. 1. water, were similarly exposed in various directions around the pile, and with the same result — destruction, except when within the protecting shadow. The experiments were varied by immers- ing stout glass tubes (Fig. 1), incased in thick paper, horizontally across the direction of the sound-rays in water, between two piles which were aligned with the dynamite cartridge. These piles were twelve feet apart, the nearer one being forty feet from the cartridge. Its shadow, therefore, just covered the second pile, and included the in- termediate water, with the middle part of each tube. After an explosion these protected parts were found to be un- broken, while the ends which projected on the two sides beyond the shadow were com- pletely shattered (Fig. 2). The boundary between the regions of shadow and noise was sharply defined on the tubes, even at a dis- tance of twelve feet behind the protecting pile. To account for the shortness of the sound-waves which were Fig. 2. SENSITIVE FLAMES AND SOUND-SHADOWS. 41 capable of producing such sharp shadows, Dr. Le Conte advances what seems to be the only tenable theory, and one which equally explains the observations of Colladon on the clicking sound of a distant bell as heard in water. In the absence of any recogniz- able pitch — for pitch implies a series of impulses recurring in regular order — there is no means of determining wave-length in these cases. But whatever this may be, the wave-length is equal to the product of the time consumed in generating the wave and the velocity of propagation. Thus, assume the initial pitch of a bell to be 220 vibrations per second. We may compute the wave- length either by considering that 220 waves are strung out over a distance of 1,120 feet, making each a trifle more than five feet long, or we may say that the time consumed in generating each wave is ?fo of a second, and that this impulse is propagated at the rate of 1,120 feet per second, which would be a little over five feet in -^ of a second. The blow of the hammer on Colladon's bell was almost instantaneous, and the intensity of the first shock thus given to the water was far greater than that of any subse- quent shock due to the succession of vibrations set up in the elas- tic bell-metal. The distance through which this intense sound would be propagated might be expected greatly to exceed that traversed by the subsequent weaker vibrations. The generating blow was so brief that the wave-length could only be short ; and hence comparatively well-defined sound-shadows were produced at a distance. In the case of the dynamite explosions under water this reasoning holds with yet greater force. If the duration of the generating impulse be only a millionth of a second, and the velocity of propagation in water be 4,700 feet per second, the resulting wave-length would be only about -^ of an inch. The quickness of action manifested in the explosion of dynamite ex- ceeds that of any other known agent that has ever been similarly employed. The duration of the generating impulse may be con- sidered indefinitely small, certainly immeasurably small. The sharpness of the sound-shadows it produces in water indicates a wave-length that can not exceed a small fraction of an inch. The production of sharp sound-shadows in air is of more recent date than the experiments in water. In 1880 a dynamite- factory near San Francisco was destroyed by the explosion of its contents. On a large building three miles away many panes of window glass on the side toward the explosion were broken, and two shocks were felt, one conducted by the air and the other by the ground. In the acoustic shadow cast by this building, nearly nine hundred feet away on the side remote from the explosion, no aerial shock was experienced, though that from the ground was distinctly felt. The shortness of the air-wave due to exploding dynamite sufficiently accounts for the sharpness of the shadow. 42 THE POPULAR SCIENCE MONTHLY. But there is now no longer any necessity to resort to such dangerous sources of sound as dynamite. Whistles may be made which yield tones exceeding twenty thousand vibrations per sec- ond. The wave-length corresponding to such a pitch is less than an inch. The advantage presented is that the sound is continu- ous, and it may be made as constant as we please by supplying the whistle from a cylinder full of compressed air, regulating the pressure by means of an appropriate gauge. The disadvantage is that the intensity is but slight, and the pitch is too high to be perceived as sound by most persons unless the ear is closely ap- plied. An artificial indicator must hence be used, whose motion under the disturbances due to sound can be seen at a distance. In 1857 Prof. John Le Conte discovered that an ordinary naked gas-flame, from a fish-tail or bat-wing burner, becomes an indicator of sound by vibrating in unison with an external source, provided the pressure be such that the flame is just ready to flare. This can be easily shown by blowing a shrill whistle or bowing a tuning-fork of high pitch in the immediate neighborhood of the flame, which at once becomes forked (Fig. 3) into several long, vibrating tongues. The effect soon ceases if the pressure be gradually di- minished. This result is due to the disturbance produced by sound - waves on the outflowing jet of gas at the nozzle. The high temperature of flame is therefore not necessary for the pro- duction of such co- vibra- tion, but serves to make it more easily manifest. Nine years elapsed after Dr. Le Conte's discovery before the subject was taken up again and independently by Mr. W. F. Barrett, in London, who used small cylindrical jets, which were found to flare under similar conditions, and could be ren- dered far more sensitive. A " pin-hole lava-tip " may be fitted into the end of a metal tube and connected by means of India- rubber tubing to a cylinder of compressed illuminating gas. In connection with this, also, there should be a water manometer gauge for regulating the pressure of the outflowing gas. If the pin-hole is very smoothly cylindrical, the flame mounts up to the height of nearly eighteen inches (Fig. 4, x), with an apparent thickness scarcely more than that of the little finger, and burn- ing quietly. When the pressure approaches ten inches, as indi- Fia. 3.— Sensitive Batwing Flames. SENSITIVE FLAMES AND SOUND-SHADOWS. 43 cated by the water-gauge, the flame flares, becoming much shorter and broader, like a little Indian club (Fig. 4, y), and producing a low roaring sound, due to the escape of unburned gas. Let the pressure now be diminished until this flaring barely ceases. The flame is now in its most sensitive condition. Sounds 1 b of low or even medium pitch have no effect upon it ; but on blowing a shrill whistle, or rattling a bunch of keys anywhere within thirty or forty feet, it flares. Perhaps the most beautiful illustration of its sensi- tiveness is given by placing an open watch near the nozzle but not touching it ; every tick causes a mo- mentary sinking and spreading of the flame, so that the effect may be seen across an audience-room. If the audience applauds with clapping of hands, the flame shrinks in acknowledgment. A very sensitive flame, but not so convenient as that of Prof. Barrett, and not visible at so great a distance, may be obtained with no pressure greater than that of the street mains, by causing the gas to issue from a small tube, over the orifice of which, at a height of an inch or two, is placed a piece of wire gauze (Fig. 5). The mixture of coal-gas and air is ignited above the gauze, and a glass tube may be used to protect the flame from currents of air, though this is not usually necessary. Very little adjustment is needed to find the distance between nozzle and gauze at which the flame is most sensitive. This arrange- ment was devised independently by Prof. Govi, of Turin, and Mr. Barry, of Ireland. The flame is de- ficient in brightness, and is only a few inches high at its best, but has the advantage of not requiring any appliances that may not be easily supplied in any town. If Barrett's flame is available, however, it is decidedly preferable to anything else. With such a flame as Barrett's it becomes possible to explore the air and detect regions of relative noise and silence' just as a delicate thermometer enables us to determine variations of temperature in different layers of air or water. If the pitch be too high for the ear to estimate or even detect it, the sensitive flame is more delicate than the ear. Armed with a whistle yielding a pitch of twelve or fifteen thousand vibrations per second, and with a good flame, many beautiful analogies between sound and light may be exhibited with entire satisfaction to an audience of deaf- mutes, if the lecturer's fingers are fairly nimble, since there is no necessity for the sounds to be heard. Most of the experiments about to be described were devised by Lord Rayleigh, the suc- Fig. 4. 44 THE POPULAR SCIENCE MONTHLY. cessor of Prof. Tyndall in the chair of Natural Philosophy at the Royal Institution in London. Let the whistle be supplied with a continuous blast of air, or any compressed gas, at steady pressure. Four or five feet away from it is placed the nozzle of the burner from which the flame issues. Its sensitiveness may be regulated at will by means of the stop-cock and the water manometer gauge. Turning on the blast through the whistle, the flame flares. Let the open hand be held up between the two ; the flaring ceases. The nozzle of the burner is in the acoustic shadow cast by the hand. If this result is not successfully attained at the first trial, the sensitiveness of the flame may be slightly modified to suit the conditions. The case is entirely analogous to that of the glass bottles in the experi- ments in San Francisco Bay. By using a small mirror to reflect the sound-waves, their lengths may easily be measured in mid-air. Let the mirror be put a few inches behind the flame and moved slowly toward this or away from it. At certain distances the flame is observed to flare violently, and at certain other points it becomes quiet, though the sound has not been varied. Reflected waves are meeting advancing waves. Where they meet in like phases, their effect on the flame is intensified. But if the position of the mirror is so adjusted that the flame is at a point where the opposing waves meet in unlike phase, these neutralize each other and the flame ceases to be agitated. The case is like that of producing loops and nodes on a string attached at one end to a vi- brating body and fixed at the other end. A series of sinusoidal curves travel over its length, and are re- flected from the fixed end, producing the so-called stationary waves (Fig. 6). A returning sinusoid is super- imposed on an advancing sinusoid, producing two loops, with an inter- mediate nodal point of rest and a node at the end. The whole sinusoid represents a wave-length, and the distance from node to node a half wave - length. The distance through which the mirror is moved from one point of flame quiescence to the next is a half wave-length for the pitch yielded by the whistle. In some experiments thus conducted by the writer, this distance was found to be a trifle over half an inch. The whole wave-length was r05 inch. Assuming the velocity of Fig. 5. SENSITIVE FLAMES AND SOUND-SHADOWS. 45 Fig. 6.— a, advancing sinusoid ; b, returning sinusoid ; c, advancing and returning sinusoids, forming two loops and a node ; c e is a whole wave-length ; c d, a half wave-length. sound to be 1,120 feet, reducing this to inches, and dividing by 1*05 inch, the pitch of the whistle was thus found to be in the neighborhood of thirteen thousand complete vibrations per sec- ond. In no other way could this pitch be determined, for the most accomplished musician loses his power of discriminating pitch when either the upper or the lower limit of audition is ap- proached. The pitch of the highest tone employed in music does not exceed five thousand vibrations per second. In performing this ex- periment Lord Rayleigh discovered an interesting peculiarity of the human ear in contrast with the sensitive flame. By using a tube, whose opening was placed alternately in the aerial loops and nodes, and conveying the sound thus to the ear at the same time that the flame was alternately agitated and quiescent, he found that the ear was most affected where the flame was least affected, and vice versa. The flame, moreover, is unequally sensitive in two directions at right angles with each other. In drilling the small cylindrical hole of the burner no amount of care is sufficient to prevent minute irregularities. The current of issuing gas is not abso- lutely cylindrical. It is disturbed slightly by interior currents from side to side, and these affect the sensitiveness of the jet to external disturbances. To test this, let the nozzle be rotated on its own axis while the whistle is sounding, until the maximum effect is noticed ; and let the sensitiveness of the flame be slightly re- duced without causing it to cease to flare. On rotating the nozzle now through a right angle the flame is found to become quiet. Let a mirror be put on one side of the flame, a short dis- tance off, so as to face the sensitive side. Adjusting it until it is equally inclined to the directions of flame and whistle, the flaring is started anew. This ceases when the mirror is rotated toward either side through a very small angle. Indeed, no more beautiful and exact illustration could be devised for showing the law of reflection of sound-waves. The sound-ray, taking a longer and broken path, disturbs the flame on its sensitive side, while the direct rays are at the same time beating in vain against what by analogy we may call its deaf side. Probably the most interesting acoustic phenomena to be in- vestigated by the aid of the sensitive flame are those of diff rac- 46 THE POPULAR SCIENCE MONTHLY. tion, or the measurable encroachment upon sound-shadows. In the accompanying diagram (Fig. 7) suppose the arrows to represent the direction of a group of parallel rays of either sound or light, the wave fronts being indicated by lines across the direction of the arrows. Waves in one phase are indicated by the continuous lines, and those in opposite phase by the dotted lines. At each edge of the obstacle are the centers of the secondary waves, whose fronts are represented by parts of circles. Behind the obstacle and on each side are points of interference represented by crosses u --—--"¥• -v Pig. 7.— Exterior and Interior Diffraction. and zeros. Behind it the secondary waves from opposite edges meet each other. At the sides, secondary waves interfere with the advancing main wave. Where like phases meet, the crosses represent points of increased disturbance. Where opposite phases meet, the zeros represent points of quiescence. If the waves are those of light, the crosses are points of increased brightness ; the zeros, of comparative darkness. If the waves are those of sound, the crosses are points of noise ; the zeros, of silence. Behind the obstacle there is a middle line of crosses ; on each side of this a line of zeros; and outside of these are lines of crosses again. These lines are parts of hyperbolas, whose foci are the centers from which the secondary waves are started. This is readily seen by reference to the next illustration (Fig. 8). A necessary conse- quence is, that if light radiating from a point or a small aperture be interrupted by interposing a small disk in its path, there should be a line along the middle of the shadow behind it, at certain points of which brightness appears if a translucent screen is placed across the shadow. This fact was noticed by a Frenchman, De- lisle, before the birth of either Newton or Huygens, but was of course not understood and was soon forgotten. Dr. Young seems not to have thought of it, or certainly never put this consequence SENSITIVE FLAMES AND SOUND-SHADOWS. 47 of theory to any test. The first physicist to recognize the value of Young's optical papers was Arago, who at once adopted the wave theory and started his friend Fresnel on a series of optical researches that are now classic. In 1819 Fresnel gained a prize from the French Academy for his work on diffraction of light. Before the report was made to the Academy it was examined by the mathematician Poisson, who criticised it by showing that, if the wave theory were ac- cepted, the shadow of a small disk should have a bright spot in the middle, due to diffraction, the illu- mination of which should be the same as if no disk had been interposed. Ara- go at once tried the ex- periment ; and what Pois- son had urged to prove the impossibility of Fresnel's views was found to be a startling proof of their correctness. The experi- ment is easily tested, re- quiring no more expensive apparatus than a mirror outside of an opening in a window, a small bullet suspended by a thin wire, and a piece of rough- ened glass to receive the shadow. A pin-hole through a sheet of tin foil covering the win- dow opening yields the required light from the mirror. The acoustic analogue of this celebrated experiment was first accom- plished a few years ago by Lord Rayleigh; it has been lately often repeated by the writer and perhaps others. A disk of card- board about a foot in diameter is put between a whistle and sensi- tive flame, with careful adjustment of distance and sensitiveness. In certain positions the flame is protected within the shadow of the disk ; but, by moving the latter to and fro, one position is found where it causes the flame to be violently agitated by the meeting of waves diffracted at the edge of the circle. The diffract- ive effect is the same as if the impervious disk were a lens con- verging the sound-waves to a focus. The effect just described may be much intensified by construct- ing an acoustic diffraction grating and using it in place of the simple disk. The explanation of the principle on which such a T' ? 3? %< f 0 1 5 T *• 6 Piq. 8.— Hyperbolas produced by Interference op Waves. 48 THE POPULAR SCIENCE MONTHLY. grating is made is beyond the scope of the present paper.* As- suming its use, the sensitive flame enables us to detect a focal area of noise, at which the flame is violently agitated, and around this are alternate rings of silence and fainter noise diminishing in strength with increase of distance from the central focus. By admitting light through two small openings close together, the waves coming from a distant bright point and hence reaching the two openings in the same phase, hyperbolic lines of interfer- ence like those shown in Fig. 8 were traced in space by Fresnel. The writer has recently done the same with sound-waves, using the sensitive flame as an explorer. Bands of alternate noise and silence have in like manner been traced by him in air, pro- duced by interference between the waves proceeding directly from the whistle and those reflected from a smooth surface placed horizontally on the table. The wave theory of sound has long been impregnable; but these beautiful analogies between light and sound, though pro- vided for by theory, have been experimentally demonstrated only recently. Such new and unexpected confirmations, new points of contact, are always welcome, even though they be not needed for the establishment of a theory. They are the results of prevision based on the assumption that an elastic material medium is needed for the propagation of sound, and are wholly inexplicable on any theory of emanation analogous to Newton's emission the- ory of light. ■»»» CONDITION'S AFFECTING THE REPRODUCTIVE POWER IN ANIMALS. By JAMES H. STOLLER, ADJUNCT PBOFE9SOR OF NATURAL HISTORY IN UNION COLLEGE. MODERN biology has made familiar the idea that animals are not fixed and unalterable in their bodily structure and functions, but, within a certain range, respond by changes in themselves to changes in their physical surroundings. This has always been observed to be true for the individual animal, as in the changes undergone in adaptation to the seasons of the year ; mammals, for instance, acquiring a thicker coat of hair at the approach of winter, and reptiles and other classes passing into a low state of functional activity called hibernation or winter sleep. But it has now been well shown that this principle of modification by environment applies to species as well as to individuals. That * For this explanation the reader is referred to an article on " Diffraction of Sound," in the " Journal of the Franklin Institute," for June, 1889. THE REPRODUCTIVE POWER IN ANIMALS. 49 is to say, in long periods of time species of animals are affected by changes in external conditions according to the same principle of natural law by which individual animals are affected in short periods. It is to be understood, of course, that species are affected by other causes than a changed environment — causes such as are included in Darwin's phrase of natural selection — but the fact of the modification of species becomes evident when it is seen that familiar observations made upon individual animals have an application to species also. It is clear that the modifications thus undergone are primarily functional rather than structural, since no part of the animal body can be altered in its anatomical characters except through phys- iological action. But it is also true that functional modifications occur not merely as subordinate to structural changes but as ends in themselves. That is to say, functional activity may be increased or diminished in response to changes in external con- ditions without any necessary sequence in changes in the struct- ure of the organs exercising the function. An illustration of this is found in the well-known fact that warm-blooded animals (ex- cepting those that hibernate) need more food in winter than in summer to keep up their normal temperature, occasioning a con- siderably increased activity of the nutritive functions, but without any attendant structural changes whatever in the organs of ali- mentation. The same holds true with hibernating animals, which, on the other hand, take no food for a long period, the nutritive function being greatly reduced in activity, yet the organs exer- cising this function undergoing no structural changes. In respect to species of animals, we should not expect to find the principle hold true so strictly as in individual animals, since increased or diminished functional activity extending through many succes- sive generations could scarcely fail to have some effect on organic structure. But the point to which special attention is here direct- ed is that function as well as structure responds to changes of environment, and that variations in functional activity occur without any closely correlated changes in structure. The present object is to show that the reproductive function in animals is profoundly affected by conditions of environment. It will be sufficient to state the law or principle according to which the activity of the reproductive power appears to be regulated, and then to adduce instances exemplifying the law. When circumstances are such that most of the ova produced are likely to develop, and the young to reach maturity, then the reproductive function is least active ; on the other hand, when by reason of lack of food-supply or danger of destruction by adverse physical conditions, or by natural enemies, it is probable that only a small proportion of the ova will give rise to mature animals, VOL. XXXTI. 4 5o THE POPULAR SCIENCE MONTHLY. then the reproductive function is most active. The law may, therefore, be stated thus : The activity of the reproductive func- tion is in proportion to the unfavorableness of the embryonic environment. The following instances are adduced : Tape- Worm. — The common tape- worm, Tcenia solium, para- sitic in the human intestine, consists in structure of a series, of flat, oblong segments, sometimes eight hundred in number. Each of these segments is sexually perfect, containing both the male and female reproductive organs. The number of ova capable of development in each sexually mature segment is probably not less than five thousand. At this time the segment detaches itself from the others and is discharged from the body. In order that the ova shall develop, it is then necessary that they should gain access to the alimentary canal of the hog. If by chance they are swal- lowed by this animal, they quickly pass into the larval or cystic stage, burying themselves in the flesh or liver of their host, whence they may be transferred to the alimentary canal of man, where development is completed. Now, it is obvious that this complex and fortuitous round of life renders the chances of the development of any single ovum exceedingly small. It is not probable, indeed, that one in ten thousand of the ova discharged from the alimentary canal of the host of the mature worm will ever reach the alimentary canal of the host of the larval worm. The embryonic environment is, therefore, in this case, exceedingly unfavorable by reason of its extreme narrowness. There is but one situation in which the de- velopment of the ovum can occur, and it is altogether accidental whether it reaches this situation. The explanation of the enor- mous capacity of the reproductive power in this animal is thus at once apparent. To compensate for the exceedingly narrow chances that the reproductive cell shall survive to complete issue, these cells are generated in excessive numbers. Aphides. — The aphides are commonly called plant-lice, and are very abundant in summer upon the leaves of most plants. They mature quickly, at least eight or nine generations following one another in a single summer. So prolific are they that it is entirely within bounds to say that a single insect may give rise to several millions of progeny, counting the successive genera- tions, within a few months. This astonishing fertility is depend- ent upon a peculiar modification of the reproductive process in these insects. During the summer there are strictly no males nor females, but all are sexually alike, and are able to produce ova which develop without fecundation, this exceptional method of reproduction being termed parthenogenesis. Here, then, we have a remarkable variation of the reproductive function resulting in an enormous increase of prolificness. And here again we find an THE REPRODUCTIVE POWER IN ANIMALS. 51 explanation of this yariation in the conditions under which the young develop. These insects are a common prey for other ani- mals, especially birds, which devour them in great numbers, their exposed condition upon the surface of leaves rendering them easily obtainable. Hence it is that of the total number of ova produced only a very small proportion result in an increase of their kind, the young insect being devoured before completing maturation. This extraordinary and anomalous increase of the reproductive power thus furnishes an extreme instance of the operation of the law under consideration. The Oyster. — It is well known that the oyster is very pro- lific. A single individual may produce over a million young. It is generally known, too, that this animal has many natural ene- mies, the most destructive being the star-fish. It is obvious that the reproductive power is here in relation to the unfavorableness of the natural environment, and especially during the embryonic period, when the body is small and less adequately protected, being destitute of a shell in the earliest stages. The Codfish. — While most fishes produce eggs in great numbers, the cod is especially remarkable in this respect, a single female depositing annually eight or nine millions. The liability of destruction of the ova and young is perhaps at its maximum here, there being many natural enemies and very slight means of defense. The application of the law is obvious. It seems unnecessary to bring forward other instances to show that the law holds good when the conditions of embryonic life are unfavorable. While it can not be so strikingly shown when the opposite conditions prevail — when the circumstances of embry- onic life are favorable — it scarcely seems doubtful that it is less applicable here. When animals have abundant food-supply and ample protection against their foes and against exposure to weath- er, etc., the reproductive function is generally only moderately active. Without citing particular instances, it may be sufficient to point out that the largest and most intelligent animals — those that are strongest in body and quickest in instincts, and thus best able to defend themselves and their young against their ene- mies and to secure food and shelter — are the least prolific, bring- ing forth young at longer intervals and in fewer numbers. It may have occurred to the reader that while there thus seems to be a law governing the procreative power in animals, this law is yet subordinate to another more general, more fundamental law — the law of the preservation of the species. Nature guards against the destruction of her works, and the instances of excessive activity of the reproductive function we have noted are to be in- terpreted as efforts made in the economy of nature to save the species from extinction. 5z THE POPULAR SCIENCE MONTHLY. ISRAELITE AND INDIAN: A PARAELEL IN PLANES OF CULTURE.* Br GAERICK MALLERY. I. AXIOMS and postulates long limited man's study of man. This hampering has been peculiarly marked in reference to America, the assumption being that it must have been peopled from the eastern hemisphere, and that its languages, religions, and customs must have been inherited from nations registered in Eurasian records. Whatever was found here was assumed to have come through descent or derivation. The conceptions of autogeny and of independent growth, by which men in the same plane of culture act and think alike, with only the modifications of environment, had not arisen to explain observed facts. Many authors have contended that the North American Indians were descendants of the " ten lost tribes of Israel." Prominent among them was James Adair, whose work, highly useful with regard to the customs of the southeastern Indians, among whom he spent many years, was mainly devoted to proof of the proposi- tion. The Rev. Ethan Smith is also conspicuous. Even the latest general treatise on the Indians, published last year, and bearing the comprehensive title, " The American Indian," favors the same theory. The authors of the school mentioned rest their case on the fact, which I freely admit with greater emphasis, that an astound- ing number of customs of the North American Indians are the same as those recorded of the ancient Israelites. The lesson to be derived from this parallel is, however, very different from that drawn by those who have advocated the descent in question. The argument, strongly urged, derived from an alleged simi- larity between Hebrew and some Indian languages, especially in identity of certain vocables, may be dismissed forthwith. Per- haps the most absurd of all the coincidences insisted upon by Adair was the religious use of sounds represented by him to be the same as the word Jehovah. The " lost " Israelites when de- ported did not use orally the name given in the English version as " Jehovah," and the mode of its spelling and pronunciation is at this moment in dispute, though generally accepted as Jahveh ; therefore, it would be most extraordinary if the tribes of Indians supposed to be descendants of the lost ten tribes of Israel should at this time know how to pronounce a name which their alleged ancestors practically did not possess. * Address of the Vice-President of the American Association for the Advancement of Science, Section H, Anthropology, delivered at the Toronto meeting, August, 1889. ISRAELITE AND INDIAN. 53 Father Lafiteau was so much excited by coincidence in sound of some of the Iroquoian names and expressions with the language of the ancient inhabitants of Thrace and Lycia that he based thereon a theory of descent. On similar grounds ancestors of the Indians have been found among the Phoenicians, Scandinavians, Welsh, Irish, Carthaginians, Egyptians, Tartars, Hindus, Malays, Chinese, Japanese, and all the islanders of Polynesia. It is not wonderful that, with the choice of three hundred Indian lan- guages, besides their dialects, from which to make selections of sounds, some one should be likened to some other language, for all spoken languages can in that manner — i. e., by a comparison of vocables — show identity of sound and a percentage of coincidences of significance. Philology now applies more discriminating rules of comparison. But all arguments that the Indians are descended from the " lost tribes " are demolished by the fact, now generally accepted, that those tribes were not lost, but that most of their members were deported and absorbed, their traces remaining during centu- ries, and that others fled to Jerusalem and Egypt. If any large number of them had remained in a body, and had migrated at a time long before the Columbian discovery, but later than the capture of Samaria in the seventh century b. c, their journey from Mesopotamia to North America would have required the assistance of miracles that have not been suggested except in the Book of Mormon. For brevity, the term "Indians" may be used — leaving the blunder of Columbus where it belongs — without iterating their designation as North American, though I shall not treat of the aboriginal inhabitants south of the United States. This neglect of Mexico and Central and South America is not only to observe my own limits, but because some of the peoples of those regions had reached a culture stage in advance of the northern tribes. To avoid confusion, the term " Israelites " may designate all the nation. Although the tribes became divided into the kingdoms of Israel and of Judah, when it is necessary to speak of the north- ern tribes they may be designated as the kingdom of Samaria. The shortest term, Jews, would be incorrect, as the people now scattered over the world and called " Jews " are chiefly the de- scendants of the southern branch or fractional part of the chil- dren of Israel, and have a special history beyond that common to them and their congeners. The parallel presented is not selected because its two counter- parts are more similar to each other than either of them is to other bodies of people among the races of the earth. A similar parallel can be drawn between both the Indians and the Israelites and the Aryan peoples, from which I and most of my hearers are supposed 54 THE POPULAR SCIENCE MONTHLY. to have descended. The selection is made for convenience, because this audience is assumed to be familiar with the Old Testament, so that quotations and citations from it are less necessary ; and also because many of them in this, the Anthropologic Section, are familiar with the Indians, so that the collocation of facts without a prolix statement is sufficient for comparison. Although the Indians are divided into fifty-eight linguistic stocks and three hundred languages, and although there is great variety in their manners, customs, and traditions, yet there is suf- ficient generic resemblance between all of them to afford typical instances, where European civilization and missionary influence have not effected serious change, or where the early authorities are reliable. It is essential to examine the other side of the parallel — the Israelites — at a period coincident in development with that of the Indians. That part of the history and records of the Israel- ites must be chiefly considered which relates to the times before they had formed a nationality and had become sedentary. The general use of writing was nearly contemporaneous with that nationality, and the era of King David is a proper deniarkating line. The Indians never having arrived at the stage of nation- ality, though some of them (as the Iroquois and the Muskoki) were far on the road to it, and never having acquired a written language, their silage of culture at the Columbian discovery shows a degree of development comparable with that of the Israelite patriarchal period and the early Canaanite occupation before the rule of kings. It is important to establish the time when writing was first known among the Israelites, because then their traditions would first become fixed. No reliable history can exist before writing. An illiterate people remembers only fables and myths ; from these the history of the years before writing was used must be win- nowed. There is no reason to suppose that the Hebrew language was written at the time of the exodus, though some such mnemon- ic system might have been invented as was used by several of the Indian tribes. If Moses had all the knowledge of the Egyptians, but no more, he could not have used any better mode of writing than their hieratic, in which it was not possible to write intelligibly any long document in the Hebrew language, simply because the advance made by the hieratic, in which the use of phonetics be- gan, was not sufficient to express all the Hebrew vocables. There has been an attempt to show that the old Hebrew alpha- bet, which has been classed as partly Phoenician and partly Baby- lonian, was obtained from Assyria at a time before the exodus, but the proposition is not yet established. Even if Assyrian characters adaptable to the Hebrew language did then exist, it is not probable that the Israelite herdsmen and bondmen did so ISRAELITE AND INDIAN. 55 adapt them. If any one of them — e. g., Moses — had done so as an individual act, the feat would have had but one historic parallel, which would have furnished another coincidence between Israel- ite and Indian. It was performed by the Cheroki, Sequoia, who in less prosaic days would have become the hero of a Kadmos myth. But Sequoia left very distinct marks of his invention, while there is no evidence that the Israelites possessed an alpha- bet before they settled in Canaan, and there are strong inferences against that supposition. The compilers of the Old Testament felt no doubt that the law could have been written on Sinai at the time of the exodus. They knew how to write and knew that their predecessors for several generations had written, so it did not occur to them that there had ever been a time in which persons of the higher classes were ignorant of writing. It is probable that in the days of Samuel the Israelites had made some progress in the art of writing. An alphabet had been known to some of them before ; but its common use is of greater consequence, and that depends much upon the substances used for writing, their cost, and the convenience of procuring them. The use, not the mere invention, of writing, not only divides the mythi- cal and the historical periods, but reacts upon the character of the people in all their institutions, forming a new epoch in culture. The people did, perhaps, write under David at about 1100 b. c. Moses flourished about fifteen centuries before Christ, and the oldest legends relating to him are, in their present shape, four or five centuries later than his death. He did not practically organ- ize a new formal state of society, or if he did, temporarily, by his personal power, it had no direct consequence or historical continu- ity. The old system of clans and religions continued as before. If the legislative portion of the Pentateuch was the work of Moses, it remained a dead letter for centuries, and not until the reign of Josiah did it become operative in the national history. The historical account undoubtedly states that Moses was, by inspiration, the founder of the Torah ; but the question is, What was that Torah ? It was not the finished legislative code. Long after the exodus a dramatic account was furnished of the pro- mulgation of the whole law at Sinai to produce a solemn impres- sion, and thus the code, which had slowly and imperceptibly grown during centuries, was represented as having been pro- nounced on one occasion celebrated by tradition as momentous. The code now ascribed to Moses was a revised code, and in an unusual sense a mosaic work. When the Israelites attained the use of writing they did as all people in the world have done when they began to use writing — i. e., they wrote out their own myths, traditions, and legends as they knew them at the time of writing. 56 THE POPULAR SCIENCE MONTHLY. But during the long time in which the traditions were transmitted orally, the growth of the nation's ideas produced a change in them without any fabrication or design, and it is probable that the traditions affected only to this extent were set forth in the earlier documents, long since lost, namely, the " Book of the Wars of Jahveh " and the " Jasar." There were, however, special temp- tations in the later history of Israel, in the contests between the Elohists and the Jahvists, to manipulate the earlier documents. When the compilers belonging to the two schools produced the two versions, intermixed and confused in the books we now have, they differed from all people in history if the contestants, for po- litical and personal power, did not color the records to suit their own views. Students who have devoted their lives to the study of the last compilation have been able to identify, by linguistic and historical exegesis, the fragments of the original traditions, the epic tales of the first documents, the theocratic deductions and the later sacer- dotal visions, though the two versions appear on the same page and sometimes in the same paragraph. The results of this im- mense labor by the Hebraists of this generation have lately been presented by Renan in a popular form. His works, as well as those of other authors whose names will be mentioned in this ad- dress, I have used freely, though generally without exact quotation. In addition to the linguistic and historical tests, other internal evidences, especially the antedating of conceptions several centu- ries (some instances of which will be mentioned), show that the books, as now presented, were written long after the periods re- ferred to in them. The main document on the primitive age is the Book of Gene- sis, regarded for the reasons mentioned, not as literally historical, but as the tradition, written at a respectable antiquity, of an age that really existed. In examining it the historical part is discov- ered, not by belief in the miraculous, but by the proper compre- hension of the mythical. Much can be learned from myths and legends of the times an- terior to strict history. The Homeric epics are not history, yet they throw a flood of light upon Greek life a millennium before the Christian era. The ante-Islam tales and the Arthurian and Niebelungen romances of the middle ages are not true in fact, yet they are storehouses, preserving the social life of the days when they were composed and to a less though still useful degree of the time embraced by the still earlier traditions. The generalizations derived from the details of ancient texts are truths obtained by induction. It is expedient to make a disclaimer before entering upon the necessary comparisons of religions. I absolutely repudiate any ISRAELITE AND INDIAN. 57 attack upon any religion. Let us learn a lesson from the Indians, not only in tolerance but in politeness. One of the early Jesuit missionaries in Canada recounts how he pleased a Huron chief by his discourse upon the cosmology set forth in the Scriptures, and felt that he had secured a convert until the chief, thanking him for his information, added, " Now you have told me how your world was made, I will tell you how my world was made " ; and proceeded to give the now familiar story of the woman falling from the sky, and the turtle. He was willing that the priest should retain his belief, with which his own, in his opinion, did not con- flict. Dr. Franklin tells of a Susquehannock who, after a similar lecture from a Swedish missionary, was answered in the same manner ; but this missionary became angry and interrupted the Indian, whereupon the latter solemnly rebuked him with pity : " I have listened politely to what you told me ; if you had been prop- erly brought up, you would have believed me as I believed you." Religion, as accurately denned, embraces only the perficient relations between divinity and man, and the mode in which such relations operate. Popularly it includes cosmology and theology. For present convenience the broad subject may be divided into Religious Opinions and Religious Practices. In this comparison, all religious views personally entertained must be laid aside and the study conducted strictly within the scope of anthropology. Modern thinkers adopt the rule not to use a miraculous factor when unnecessary. Nee deus intersit, nisi dignus vindice nodus. It is now regarded as puerile to ex- plain all puzzling phenomena, as was done for ages — " When solved complete was any portent odd By one more story or another god." This attitude, however, is still not universal. When experi- ence of observed facts and of the orderly working of the forces of nature are not sufficient for explanation, some minds yet resort to the miraculous. Others humbly confess ignorance and work for light. This light when gained is real and lasting, not the delusive hues of cloud-region, varying with each instant and to each ob- server's eye, and soon resolving into the same old mists and fogs from which escape was sought. In their explanation of phenomena, all the peoples of the world have resorted to revelations. Every myth or early teaching is directly or indirectly through revelation ; but as the revelation is on both sides of the equation, it can be eliminated from any paral- lel such as is now presented. A cardinal of more than titular eminence was rash when, ad- mitting that the doctrine of the devil and his command of demons was first learned by the Israelites during the Babylonian captiv- 5 8 THE POPULAR SCIENCE MONTHLY. ity, lie insisted that it might "be divine revelation, notwithstanding its immediate source. He said that if God made Balaam's ass speak, it would also be easy for him to provide that the heathen should give correct instruction. The non-existence of Satan is not demonstrable ; so it may be well to examine into subjects on which we have knowledge, such as geology and astronomy. It appears from bricks in palaces at Nineveh that the Mosaic cosmol- ogy was also obtained from the same source as the Satanic doctrine. Any revelation on the subject would in order of time have been given to, and according to all evidence was promulgated by, the cultured Assyrians, not the ignorant captives. The priority, however, is of little moment, as the revolving dish-cover theory, whether as originally noted on clay or on rolls of sheep-skin, is now obsolete. All dependence on revelations practically means that those suiting us are true and all others false. When judgment upon the truth or falsehood of an alleged revelation can be made in accordance with the prejudices of the judge, the subject be- comes too eclectic and elastic to be considered by science, or indeed by common sense. The scope of anthropology is to study within the category of humanity. If theology comes from man's conceptions, it is em- braced in anthropology. If theology is of divine origin, anthro- pology may discuss what men think and do about it. But the truth or falsity of revelation can not be dealt with in this ad- dress. To raise that point acts as a cloture, cutting off all debate. Religious Opinions. — Religious writers have often explained the differences in beliefs among the various peoples of the world on the hypothesis that true religious knowledge was implanted at one time in the ancestors of all those peoples, and that the diver- gence now found is through decay of that supernatural informa- tion. The early missionaries to America, of all denominations, were imbued with this dogma and sought, and therefore found, evidences of the one primeval faith. Sometimes they limited them- selves to the similar beliefs of the Indians and the Israelites, but often they passed beyond that stage to locate the vestiges of Chris- tianity. These they said came by the hands of Christian pre- Columbian visitors, and one explanation was by the importation of the apostle Thomas. The coincidences found were exagger- ated, but when facts were opposed they were not less satisfactory, as the adverse power of Satan then appeared. Such mental prede- termination nearly destroys the value of those missionary accounts. The most generally entertained parallel between the Indians and the Israelites, repeated by hundreds of writers, was that they both believed in one overruling God. This consensus, if true, would at once establish a beatific bridge of union between the two peoples, but its iris arch vanishes as it is viewed closely. ISRAELITE AND INDIAN. 59 After careful examination, with the assistance of explorers and linguists, I reassert my statement, published twelve years ago, that no tribe or body of Indians, before missionary influence, enter- tained any formulated or distinct belief in a single, overruling " Great Spirit/' or any being corresponding to the later Israelite or the Christian conception of God. All the statements of the missionaries and early travelers to the opposite effect are errone- ous. Even some of the earliest writers discovered this truth. Lafiteau says that the names " Oki " and " Manito " were given to various spirits and genii. Champlain said that Oki was a name given to a man more valiant and skillful than common. Manito signifies " something beyond comprehension." A snake was often a manito, and seldom were snakes molested. "Hawaneu," re- duced to correct vocables, only means loud-voiced — i. e., thunder. " Kitchi Manito " is not a proper name for one god, but an appella- tion of an entire class of great spirits. So with the Dakota term " Wakan," which means only the mysterious unknown. A watch is a wakan. The Chahta word presented as " God " for two centu- ries is now found to mean a " high hill." Some Indians, perhaps, had a vague idea of some good spirit or being whom they did not worship and to whom they did not pray. They prayed and sacrificed to the active daimons, concerning whom they had many myths. In their various cosmologic myths there was sometimes a vague and unformulated being who started the machinery by which the myth proceeded; but when once started no further attention was paid to such originator. Per- haps some modern advanced thinkers have no clearer definition of a great first cause. Praise has been lavished upon the Indians because they did not take the name of God in vain. The true statement, however, has a different significance. They did not, according to the best linguistic scholars, have any word corresponding with the English " God " either to use or misuse, and they deserve no more praise for avoidance of profanity than for their total abstinence from alcoholic drinks before such had been invented or imported. The terms too liberally translated as " Master of Life " and " Maker of Breath " were epithets merely. Perhaps there was an approach to a title of veneration when the method of their clan system was applied to supernatural persons, among whom there would natu- rally be a chief or great father of the " beast gods," on the same principle as there was a chieftaincy in tribes. The missionaries who have persistently found what did not exist are not without excuse. Wholly independent of any design to force welcome answers, an interviewer who asks a leading ques- tion of an Indian can always obtain the answer which is supposed to be desired. The sole safe mode of reaching the Indian's men- 60 THE POPULAR SCIENCE MONTHLY. tal attitude is to let him tell his myths and make his remarks in his own way and in his own language. When such texts are written out, translated, and studied they are of great value. It is only within about twelve years that this has been done in a systematic manner, but it has already resulted in the correction of many popular errors. In attempting to translate the epithets mentioned, the mis- sionaries and travelers often honestly used the word which, in their own conception, was the nearest equivalent. An instructive ex- ample is where Boscana describes a structure in southern Cali- fornia as a " temple." It was a circular fence, six feet high, not roofed in — a mere plaza for dancing ; but the dancing was reli- gious, and the word " temple " was the best one he could find, by which mistake he has perplexed archaeologists who have sought in vain for the ruins. A consideration not often weighed is that the only members of the Indian tribes who are willing to give their own ideas on religious matters to foreigners are precisely those who are most intelligent and most dissatisfied with their old stories. There were minds among them groping after something newer and bet- ter, and it would be easy to translate their vague longings into the conception of an overruling Providence. But the people had made no such advance. The missionaries who announced that the Indians were fixed in the belief in one god were much troubled by the statement of the converted native, Hiaccomes, of Martha's Vineyard, who, hav- ing enumerated his thirty-seven gods, gave them all up. This, however, was a typical instance of the truth. The Indians had an indefinite number of so-called gods corresponding with the like indefinite number of the Elohim of the Israelites before the su- premacy of Jahveh. The biblical religion of Israel has been popularly held to be coeval with the world, but its own beginning was by no means archaic. About a thousand years before Christ it did not exist, and at least four hundred years were required for its develop- ment. The religious practices of David and Solomon did not materially differ from those of their neighbors in Palestine. Not until the time of Hezekiah, about seven hundred and twenty-five years before Christ, did the Israelite religion attain to a distinct formulation. Its ordinances and beliefs advanced from crudity and mutation to ripeness and establishment. It was a system long in growth, and so could not early possess authoritative docu- ments. The nomad Semite believed, with other barbarians, that he lived amid a supernatural environment. The world was sur- rounded and governed by the Elohim — myriads of active beings, ISRAELITE AND INDIAN. 61 seldom with distinct proper names, so that it was easy to regard them as a whole and confound them together. Yet the power bore different names in different tribes. In some cases it was called El, or Alon, or Eloah ; in other cases Elion, Saddai, Baal, Adonai, Ram, Milik or Moloch. The Elohim, though generally bound together, sometimes acted separately ; thus each tribe gained in time its protecting god, whose function was to watch over it and direct it to success. In the transition to nationality, the Israelites conceived a na- tional god, Jahveh, who was not just, being partial toward Israel and cruel toward all other peoples. The worship of a national god is not monotheistic, but henotheistic, recognizing other gods of other peoples. The work of the later prophets consisted in restoring the attributes of the ancient elohism under the form of Jahveh, and in generalizing the religious cult of a special god. Jahveh was not at first the god of the universe, but subse- quently became so because he was the God of Israel, and very long afterward was claimed to be the only god, mainly because the Israelites claimed to be the peculiar people. Even down to the time of the prophet Isaiah, there was alternation of conflict and of co-ordination between Jahveh and the other gods of Canaan, especially Baal. The revolution accomplished by the prophets did not change expressions. The concept of Jahveh was too deeply rooted to be removed, and the people spoke of Jahveh as they had formerly spoken of the Elohim. He thus became the supreme being who made and governed the world. In time even the name of Jahveh was suppressed and its utterance forbidden ; and it was replaced by a purely theistic word meaning the Lord. Undoubtedly the prophets, at the time of the kings and later, taught the worship of one God, but the people were not converted to the doctrine un- til after the great captivity. When established in Palestine, the Israelites entered into com- munion with the Canaanites, their kindred, and worshiped Baal. Later they frequently bowed down to the Dagon of the Philistines, probably because he was the god of their warlike victors. Solo- mon, perhaps from admiration of Sidonian culture, introduced the service of Astarte, which was intermitted ; but later, Ahab estab- lished the worship of the Sidonian divinities in the kingdom of Samaria. It was subsequently readopted in the kingdom of Judah, and not until the reign of Josiah were the Sidonian altars finally demolished. The true parallel, therefore, between the Indians and the Israelites, as to belief in a single overruling God, is not that both, but that neither, held it. In the stage of barbarism all the phenomena of nature are 62 THE POPULAR SCIENCE MONTHLY. attributed to the animals by which man is surrounded, or rather to the ancestral types of these animals, which are worshiped. This is the religion of zootheism. Throughout the world, when advance was made from this plane, it was to a stage in which the powers and phenomena of nature are personified and deified. In this stage the gods are anthropomorphic, having the mental, moral, and social attributes of men, and represented under the forms of men. This is the religion of physitheism. The most advanced of the Indian tribes showed evidence of transition from zootheism to physitheism. The Israelites, in the latter part of the period selected, showed the same transition in a somewhat higher degree than the Indians did when their independent prog- ress was arrested. It is needless to enlarge upon the animal gods of the Indians, or to furnish evidence that they gave some vague worship to the sun, the lightning, to fire and winds. There is no doubt that the Israelites were for a long period in the stage of zoolatry. They persisted in the worship of animal gods — the golden calf, the brazen serpent, the fish-god, and the fly-god. The second commandment is explicitly directed against the worship of the daimons of air, earth, and water, which is known to have been common ; and the existence of the prohibition shows the necessity for it, especially as it was formulated, after the practice had existed for centuries, by a religious party which sought to abolish that worship. The god of Sinai was a god of storm and lightning, which phenomena were strange to the Israelites after their sojourn in plains. The ancient local god of the Canaanites began in the exodus to affect the religious concepts of the Israelites, so that they associated Jahveh with the god whose lands they were plant- ing and whose influence they felt. Sinai was thenceforward the locality of their theology. Jahveh, through all after-changes, remained there as his home ; he spoke with the voice of thunder, and never appeared without storm and earthquake. Another class of gods connected with beast-worship and also with the totemic institution (to be hereafter specially noted) was tutelar, the special cult of tribes, clans, and individuals. It was conspicuous both among the Israelites and the Indians. Jahveh may first have been a clan or tribal god, either of the clan to which Moses belonged or of the clan of Joseph, in the pos- session of which was the ark. No essential distinction was felt to exist between Jahveh and El, any more than between Ashur and El. Jahveh was only a special name of El, which had become current within a powerful circle, and which, therefore, was an acceptable designation of a national god. When other tutelar gods did not succeed, there was resort to Jahveh, probably in the early in- ISRAELITE AND INDIAN. 63 stances because he was the most celebrated of all the tutelar gods, and the reason for that celebrity was that the most powerful of the clans claimed him as tutelar. Hecastotheism is a title given to the earliest form of religion known, which belongs specially to the plane of savagery. In it every object, animate or inanimate, which is remarkable in itself or becomes so by association, is a quasi god. The transition be- tween savagery and barbarism, as well as between the religions of hecastotheism and zootheisin, connected with them, was not sharply marked, so that all their features could coexist at a later era, though in differing degrees of importance. This intermixture is found both among the Israelites and In- dians. An illustration among many is in the worship of localities and of local gods. Conspicuous rocks, specially large trees, pecul- iar mountains, cascades, whirlpools, and similar objects received worship from the Indians ; also the places where remarkable oc- currences, as violent storms, had been noted ; and among some tribes the particular ground on which the fasting of individuals had taken place, with its accompanying dreams. The Indians frequently marked these places, often by a pile of stones. The Dakotas, when they did not have the stones, used buffalo skulls. In the Old Testament frequent allusions are made to a place becoming holy where dreams or remarkable events had occurred. They were designated by pillars. The Israelite compilers adopted the pillar of Bethel for the same reason that required Mohammed to adopt the Caaba. Though struggling for monotheism, they could not always directly antagonize the old hecastotheism. Future State. — The topic of a future state may be divided into (1) the simple existence of the soul after death, (2) the resurrec- tion of the body, and (3) a system of rewards and punishments in the next world. The classical writers often distinguished two souls in the same person — one that wandered on the borders of the Styx until the proper honors had been given to the corpse; the other being a shadow, image, or simulacrum of the first, which remained in its tomb or prowled around it. The latter could be easily invoked by enchanters. Some of the Indians thought that the souls of the dead passed to the country of their ancestors, from which they did not dare to return because there was too much suffering on the road forward and backward. Nevertheless, they believed that there was some- thing spiritual which still existed with their human remains, and they tell stories of it. Thus there are two souls, and the Dakotas have four, one of which wanders about the earth and requires food, the second watches over the body, the third hovers around the village, and a fourth goes to the land of spirits. 64 THE POPULAR SCIENCE MONTHLY. The Iroquois and Hurons believed in a country for the souls of the dead, which they called the " country of ancestors." This is to the west, from which direction their traditions told that they had migrated. Spirits must go there after death by a very long and painful journey, past many rivers, and at the end of a narrow bridge fight with a dog like Cerberus, and some may fall into the water and be carried away over precipices. This road is all on the earth ; but several of the Indian tribes consider the Milky Way to be the path of souls, those of human beings forming the main body of the stars, and their dogs, which also have souls, run- ning on the sides. In their next world the Indians do the same as they customarily do here, but without life's troubles. The Israelites believed in a doubling of the person by a shadow, a pale figure, which after death descended under the earth and there led a sad and gloomy existence. The abode of these poor beings was called Sheol. There was no recompense, no punish- ment. The greatest comfort was to be among ancestors and rest- ing with them. There were some very virtuous men whom God carried up that they might be with him. Apart from these elect, dead men went into torpor. Man's good fortune was to be accord- ed a long term of years, with children to perpetuate his family and respect for his memory after death. The Indians did not believe in existence after death in a posi- tive and independent state. The spirit does not wholly leave the body and the body is not resurrected. Perhaps a good commen- tary upon their belief is furnished by a tribe of Oregon Indians who, hearing missionaries preach on the resurrection, imme- diately repaired to an old battle-field and built great heaps of stones on the graves of their fallen foes to prevent their coming up again. They did not want any of that. Among the Israelites the resurrection of the body was a for- eign idea imbibed during the captivities in Assyria and Babylo- nia. Perhaps the first reference made to it is in the prophet Dan- iel. It was not fully believed in so late as the procuratorship of Pontius Pilate. Among the Indians privation of burial and funeral ceremonies was a disgraceful stigma and cruel punishment. There was trouble about children who died shortly after their birth, and also about those whose corpses were lost, as in the snow or in the waters. In ordinary cases of death the neglect of full and elaborate ceremo- nies caused misfortune to the tribe. The story of the " happy hunting-ground " among the Indians has not been generally apprehended. As regards what we now consider to be moral conduct there was no criterion. A good In- dian was one who was useful to his clan and family, and at the time of his death was not under charges of violating the clan rules , ISRAELITE AND INDIAN. 65 for which the Polynesian word tabu has "been adopted. The moral idea of goodness of a Pani chief is to be a successful warrior or hunter. The actual condition at the moment of death decided the condition in the future far more than any conduct during the past. In the portions of the continent where the scalp was taken, the scalped man remained scalped in the world of spirits, though some tribes believed that scalping prevented his reaching that world. If he had but one leg or eye here, he had but one leg or eye after- ward. In tribes where they cut off the ears of slain foes the spirit remained without ears. A special instance is where the vic- tim was considered too brave to be scalped, but the conquerors cut off one hand and one foot from the corpse to keep him from in- flicting injury upon the tribe of the conquerors in the next world. Some of the tribes thought that if an Indian died in the night he remained in total darkness ever afterward. One of the most curious of their beliefs was in connection with drowning and hanging, the conceit being that the spirit (which was in the breath) did not escape from the body. This doctrine was made of special application to prevent suicide, which was generally performed either by hanging or drowning, the deduction being that suicides could not go to the home of the ancestors. It is probable that the various trials which the spirit is sup- posed to undergo before reaching the other world were devised to secure 'confidence in the absence thereafter of the ghosts of the dead, because the same difficulty would attend their return. As without the assistance of mortuary rites the ghosts would not be able to reach their final home, their permanent absence was se- cured because there were no repetitions of those rites to assist their return. Fear of the ghosts, not only of enemies but of the dearest friends, generally prevailed. After a death all kinds of devices were employed to scare away the spirit. Sometimes a new exit, through which the corpse was taken, was cut through the wigwam and afterward filled up, it being supposed that the spirit could re-enter only by the passage through which it went out. Some- times the whole wigwam was burned down. There was often a long period, which travelers called that of mourning, during which drums and rattles were used to drive away the spirits. After firearms were obtained, they were discharged in and around the late home of the deceased with the same object. The loud cries of so-called lamentation had probably a similar origin, and this is more marked when the lamenters were strangers to the dead, and even professionals, not unlike the Irish keeners. In this general connection it is proper to allude to the common abstinence from pronouncing the true name of any dead person. This is more distinct than the sociologic custom where the man's true name should not be used in his life except on special occa- VOL. XXXVI. — 5 66 THE POPULAR SCIENCE MONTHLY. sions. There was some fear that, by calling his name, he might come back. It would be wrong to accuse the Indians of want of feeling in- dicated by their horror of the dead. In one of the most ancient accounts — that of Cabeza de Vaca — it is declared that the parents and other relatives of the sick show much sympathy while life re- mains, but give none to the dead — do not speak of them or weep among themselves, or make any signs of grief or approach the body. This domestic reticence is entirely different from, but not antago- nistic to, the obligatory mortuary rites which were practiced. To secure the living from the presence of the spirits of the dead was the first object, and the second was to assist those spirits in the journey to their destination. These were the prevailing ideas of all the mortuary customs of the Indians. It may be true that there was in some cases (though missionary influence is to be suspected) a belief that there were two different regions in which the bad and the good would severally remain, but that was not of general acceptance. There was but one future country, and the only question was whether the spirits got there or not. There was no hell. The Israelites, in their sacred books, do not show the influence of fears or hopes concerning a future state with reference to indi- vidual morality. Among them death at any age was not an inevi- table necessity, as they thought that life might be prolonged to an indefinite extent, but it was inflicted as a punishment and their signs of mourning were acts of penitence and contrition, with the idea that the survivors might have been the cause of the death. All deaths were classed with public calamities, such as pestilence, famine, drought, or invasion, being the work of an enemy — per- haps a punishing god, perhaps a daimon or a witch. They re- garded it so great an evil to die unlamented that it was one of the four great judgments against which they prayed, and it was called the burial of an ass. These are the inferences to be derived from the books as we have them. It is, however, questionable whether rites attending upon death were not with them similar in intent to those of the Indians — i. e., to provide, by means of those rites, for the future welfare of the departed, rather than in accordance with our modern sentiment, to show respect and personal sorrow. Passages of the Old Testament may be noted — e. g., the one tell- ing how the bodies of Saul and his children were rescued from Bethshan and taken to Jabesh, where they were burned and the bones buried. The ceremony in this case and others seems to have been the burning of the flesh and the burial of the bones, as was frequently done by the Indians on occasions of haste, without waiting as usual for the decay of the flesh, the later gathering of the bones being at stated periods of years. There is no evidence that the Israelites feared the corpse and ISRAELITE AND INDIAN. 67 its surroundings "beyond that to be inferred from the ordinances concerning pollution, which, however, are significant. Religious Practices. — There should, always be a cross-refer- ence in thought between what in time became a religious practice and the earlier sociology, to be mentioned in its place, with which it was closely connected. Josephus remarks about the Israelites that " beginning imme- diately from the earliest infancy, nothing was left of the very smallest consequence to be done at the pleasure and disposal of the person himself." The same is true regarding the Indians. Their religious life is as intense and all-pervading as that of the Israelites. It is yet noticed in full effect among tribes as widely separated, both by space and language, as the Zuni and the Ojibwa, and their prac- tices are astonishingly similar in essence and even in many details to some of those still prevailing in civilization. Among the Hurons and Iroquois there were religious rites for all occasions, among others for the birth of a child, for the first cutting of its hair, for its naming, and for its puberty, for the ad- mission of a young man into the order of warriors, and the pro- motion from warrior to chieftain, for making a mystery-man, for first using a new canoe, for breaking tillage-ground, for sowing and harvest, for fixing the time to fish, for deciding upon a war- like expedition, for marriages, for the torturing of captives, for the cure of disease, for consulting magicians, invoking the daimons, and lamenting the dead. Shamans. — Among the Indians there was frequently an estab- lished and recognized priesthood, provided by initiation into secret religious societies, corresponding in general authority to that of the Levites, although the order of the latter was instituted in a different manner, perhaps imitated from the exclusive class of the priesthood in Egypt. The shamans in all tribes derived a large part of their support from fixed contributions or fees. Adair describes a special ceremony for the admission or conse- cration of a priest among the southern tribes, as follows : " At the time of making the holy fire for the yearly atonement of sin the Sagan clothes himself with a white ephod, which is a waistcoat without sleeves, and. sits down on a white buckskin, on a white seat, and puts on it some white beads, and wears a new pair of white buckskin moccasins, made by himself, and never wears these moccasins at any other time." Similar exclusive use by the high priest of the garments used on the day of the atonement is mentioned in Leviticus. In addition to the organized class referred to, there were other professional dealers in the supernatural who may be called con- jurers, sorcerers, or prophets. They were independent of and often 68 THE POPULAR SCIENCE MONTHLY. antagonistic to the regular shamans. Instance the Jossakeed of the Ojibwa, rivals of the Mide*, as the Israelite prophets were of the Levites. At the time of the Judges the prophets were isolated and without any common doctrine. These irregular practitioners arrived at recognition individually by personal skill in an exhibi- tion of supernatural power — that is, they wrought miracles to prove themselves genuine. At the time of the exodus there were, among all the Semitic tribes, sorcerers who possessed mysterious secrets and enjoyed some of the power of the elohim. They were paid to curse those whose ruin was desired. Balaam was the most distinguished sor- cerer of that time. One of the most frequent purposes for employing supernatural agency was to bring on rain in time of drought. The practi- tioner generally tried to delay his incantations as long as possi- ble in hopes of a meteorologic change. Sometimes, on failure, he was killed, as he was supposed to be an enemy who possessed the power he professed but was unwilling to use it ; and to prevent this dangerous ordeal in a dry season, he charged in advance cer- tain crimes and "pollutions" against the people, on account of which all his skill would be in vain. The more skillful rain-makers among the Sioux and the Mandans managed not to be among the beginners, but toward the last of the various contestants. The rain would surely come some time, and when it came the incanta- tions ceased. The shaman who held the floor at the right time produced the rain. Frequent reference to rain-making is found in the Old Testa- ment, in which the prophets were the actors. The mystery-men were consulted on all occasions as sources of truth, not only to explain dreams, but to disclose secrets of all kinds ; to predict successes in war ; to tell the causes of sickness ; to bring luck in the hunt or in fishing ; to obtain stolen articles ; and to produce ill luck and disease. Their processes, together with thaumaturgic exhibitions, included some empiric knowledge, and also tricks of sleight-of-hand and hypnotic passes. The Chahta had a peculiar mode of finding the cure for dis- ease, by singing successively a number of songs, each one of which had reference to a peculiar herb or mode of treatment. The pref- erence of the patient for any song indicated the remedy. The Israelites believed that diseases as well as accidents with- out apparent cause, and other disasters, were the immediate acts of the elohim or were caused by evil spirits ; therefore they relied upon prophets, magicians, or enchanters for exorcism. Hezekiah's boil was cured by Isaiah. Benhadad, King of Syria, and Naaman, the Syrian, applied to the prophet Elisha. All the people resorted to their favorite mystery-men. ISRAELITE AND INDIAN. 69 Even so late as the time of Josephus it was believed that Solo- mon had invented incantations by which diseases were cured, and some handed down by tradition were commonly used. Incense banished the devil, which also could be done by the liver of a fish. Certain herbs and roots had the same power. Their medical prac- tices might be recited, with slight change of language, as those of the Indians. The further back examination is made into sav- agery and barbarism, the more prevalent faith-cure appears. Witches. — The Indians were in constant dread of witches, wiz- ards, and evil spirits ; but the activity of the good spirits was not so manifest. They, however, told Adair how they were warned by what he calls angels, of an ambuscade, by which warning they escaped. Bad spirits, or devils, were the tutelar gods of enemies, to be resisted by a friendly tutelar. The idea of a personal Satan was not found before the arrival of the missionaries. Among the Indians witches were often indicated by the dreams of victims. They were sometimes killed merely upon accusation, and it is interesting to notice, with relation to comparatively modern history, that the accused frequently confessed that they were sorcerers, and declared that they could and did transform themselves into animals, become invisible, and disseminate dis- ease. A sufficient reference to the Israelites in this connection is to quote the ordinance, " Thou shalt not suffer a witch to live." This injunction, in the higher civilization, is observed by destroying the idea that witches live, ever have lived, or ever can live. Dreams and Divinations. — The topics of inspiration by dreams and divination by oracles may be grouped together. The Indians supposed that with, and sometimes without, a spe- cial fasting, and other devices to produce ecstasy, the spirits or daimons manifested themselves in dreams. It was sometimes pos- sible in these dreams for the soul to leave the body, and even to visit the abode of departed spirits. Among the Iroquoian tribes the suggestions made by dreams were implicitly followed, not only by the dreamer, but by those to whom he communicated his dreams. For instance, an Iroquois dreamed that his life depended upon his obtaining the wife of a friend, and, though the friend and his wife were living happily, and parted with great reluctance, £he dreamer had his wish. The same tribe had a special feast which was called the " feast of dreams," and partook of the nature of Saturnalia. Every object demanded by the dreamers must be given to them. In some in- stances they were unable to remember their dreams, and the spe- cial interposition of the mystery-men was invoked to state what their dreams were in fact and what was their significance. Among the invaluable reports of the Jesuit missionaries, one 7o THE POPULAR SCIENCE MONTHLY. in 1639 gives the general statement that the Indians consulted dreams for all their decisions, generally fasting in advance ; that, in fact, the dream was the master of their lives ; it was the god of the country, and dictated their decisions concerning important matters — hunts, fishing, remedies, dances, games, and songs. The belief in revelations through dreams was universal, and the power of explaining them was also by revelation. Their le- gends on this subject recall those about Joseph and Daniel. In addition, Job xxxiii, 15, 16, may be quoted : " In a dream, in a vision of the night, when deep sleep f alleth upon men, in slumberings upon the bed, " Then He openeth the ears of men and sealeth their instruc- tion." And in Deuteronomy a prophet is equivalent to a dreamer of dreams. There were various oracles among the Indians. Those most interesting to me are connected with pictography. Among many tribes, especially the Mandan, Hidatsa and Minnitari, after cer- tain fasts and exercises, hieroglyphics deciding the questions which had been propounded appeared next morning on rocks. They were deciphered by the shaman who had made them. The apparatus by which Jahveh was consulted was the urim and thummim, a form of oracle described as connected with the ark. It ceased to be known in the fifth century before Christ, and is now but vaguely understood. From the description and tradi- tion it could, physically, have been worked by a custodian. Severe fasts were probably the most common religious prac- tices of the Indians. These were continued until they saw visions, sometimes sought for personal benefit as deciding upon their names to be adopted from the advent of a guardian spirit, and sometimes for tribal advantage. The doctrine of all of them, as Father Lafiteau quaintly observes, was the same that prevailed among many people of his day, to lead the mind from gross and carnal obstructions of the body. The real effect was to produce mental disorder. This ecstasy obtained by fasting was often ac- celerated by profuse sweating and the use of purgative or emetic drinks. Violent and prolonged exercise by dancing in a circle until the actors dropped in a swoon sometimes concluded the cere- monies. The Israelite prophets were excited to inspiration by external means, such as dances and orgiastic proceedings resembling those of the dervishes and those of the Indian mystery-men. Music was a general accompaniment of the ecstasy. When they were about to prophesy, they wrought themselves into a condition of frenzy. When Elisha sent one of the children of the prophets to anoint Jehu, it was said of him, " Wherefore cometh this mad fellow ? " ISRAELITE AND INDIAN. 71 Pollution and Purification. — The subject of pollution and puri- fication has been much and properly insisted upon as affording a striking parallel between the Israelites and the Indians. The In- dians made special huts for the women, at certain periods, when they were considered so unclean that nothing which they touched could be used. A Muskoki woman, after delivery of a child, was separated from her husband for three moons (eighty-four days). This may be compared with the Levitical law by which the mother of a female child was to be separated eighty days and of a male forty days. Dr. Boudinot says that in some Indian tribes there was similar distinction between male and female children. Among the southern Indians wounded persons having running sores were confined beyond the village, and kept strictly separate, as by the Levitical law. An Israelite dying in any house or tent polluted all who were in it and all the furniture in it, and this pollution continued for seven days. All who touched a corpse or a grave were impure for the same time. Similarly, many of the Indians burned down the house where there had been a death. Many writers have asserted, as one of the excellences of the Israelite customs, that the " purification " imposed upon those who had been engaged in a burial was a sanitary regulation, a measure rendered expedient in a hot country. As no great proportion of the Israelites generally inhabited a country hot to the degree indicated, and as none of them had any conception of disease or the cause of death, this explanation is hardly sufficient. Much later the compilers might have gained some sanitary knowledge by which the old superstition was utilized. Its true explanation is from supernatural, not from natural, concepts. It is probably connected with a point mentioned before — i. e., the avoidance of corpses from the fear of the spirit of the dead and of the bad spirit which had caused the death, and the purificatory ceremony was for the daimon, not for the disease. The neglect of sanitation is well illustrated among the Navajo, who are little affected by civ- ilization. Upon the death of one of their members they block up the shelter containing the corpse, and, from fear of the spook or of the agent of death, or of both, not from fear of the corpse itself, they never again visit it. Other tribes simply piled stones on the corpse, which prevented its disturbance by beasts, but did not absorb the effluvium. Still others exposed the dead on scaffolds. To leave corpses to putrefy freely is certainly not a sanitary meas- ure, yet it was a practice existing together with the mortuary rites before mentioned, though many of the tribes practiced earth- burial, and a few used cremation. On a broad examination of the topic of " pollution," so styled by most writers, it seems to be best explained by our recent under- standing of tabu. 72 THE POPULAR SCIENCE MONTHLY. Sacrifice. — Man once imagined forces superior to himself, who yet could be invoked and moved to and from any purpose. The divine world was produced in his own image, and he treated its gods as he liked to be treated by his inferiors. He believed that the way to placate the forces surrounding him was to win them over as men are won over, by making presents to them. This clearly continued among the Israelites until the eighth century b. c, but it is to be regarded as a stage succeeding a former condition of zoolatry and totemism, without notice of which its details can not be understood. Most people sacrificed to their divinities plants, fruits, and herbs, and animals taken from their flocks. People who had no domes- tic animals offered those taken in the hunt. The Indians offered the maize from their fields and the animals of the chase, and threw into the fire or water tobacco, or other herbs which they used in the place of tobacco. Sometimes these objects were hung up in the air above their huts. The northern Algonquins tied living dogs to high rods, and let them expire. In a similar manner other Indians stuck up a deer, especially a white deer, on poles. The plains tribes gave the same elevation to the head or skin of an albino buffalo on mounds, not having poles convenient. The spot- less red heifer of the Israelites may be compared with the spotless white animals of the chase. The southern Indians always threw a small piece of the fattest of the meat into the fire when eating or before they began to eat. They commonly pulled their newly killed venison several times through the smoke of the fire — perhaps as a sacrifice, and perhaps to consume the life-spirit of the animal. They also burned a large piece and sometimes the whole carcass of the first buck they killed, either in the winter or the summer hunt. The Muskoki burn a piece of every deer they kill. The Israelites offered daily sacrifice, in which a lamb (except the skin and entrails) was burned to ashes. In some of their sac- rifices there was not only distinction between animals that were fit and unfit, but in the manner of treatment. Sometimes the vic- tim was not to be touched, but should be entirely consumed by fire. In others the blood should be sprinkled around the altar and the fat and the entrails burned, the remainder of the body to be eaten by the priests. But it was a crime to eat flesh that had been offered in sacrifice to a false god — i. e., god of another people. The offering of the first-fruits, and therefore of the first-born, to the divinity, was one of the oldest ideas of the Semites. Moloch and Jahveh were conceived as being the fire, devouring whatever was offered to it, so that to give to the fire was to give to the god. In time, a substitute was suggested ; the first-born was replaced by an animal or a sum of money. This was called the " money of the lives." ISRAELITE AND INDIAN. 73 The "green-corn dance/' common to many Indian tribes, is essentially the same ceremony of thanksgiving, or, more correctly, rejoicing with payment, for the first-fruits of the earth. Adair says that at the festival of the first-fruits the Southern Indians drank plentifully of the cusseena and other bitter liquids, to cleanse their bodies, after which they bathed in deep water, then went sanctified to the feast. Their annual expiation of sin was sometimes at the beginning of the first new moon in which their corn became full-eared, and sometimes at the recurrent season of harvest. They cleansed their " temple " and every house in the village of everything supposed to pollute, carrying out even the ashes from the hearths. They never ate nor handled any part of a new harvest till some part of it had been offered up ; then they had a long fast " till the rising of the second sun." On the third day of the fast the holy fire was brought out from the "temple," and it was produced, not from any old fire, but by the rubbing of sticks. It was then distributed to the people. Lafiteau says that the first animal the young hunter kills he burns with fire as a sacrifice. Another festival was a kind of hol- ocaust, where nothing of the victim was left, but it was all con- sumed, even to the bones, which were burned. There were also feasts of first-fruits. The Dakotas allowed no particle of the food at any of their religious feasts to be left uneaten. All bones were collected and thrown into the water, that no dog might get them or woman tram- ple over them. It was a rule among many of the tribes that no bones of the beast eaten should be broken. There is no doubt that this was connected with zoolatry, and was intended to prevent anger on the part of the ancestral or typical animal, the result of which would be the disappearance of the game. There were many other ceremonies of the same intent. When the Mandans had finished eating, they often presented a bowlful of the food to a buffalo-head, saying, " Eat this," evidently believing that, by using the head well, the living herds of buffalo would still come and supply them with meat. It is probable that what many authors have called the " day of atonement " or " expiation " was really a general wiping out of offenses — a settlement of accounts between individuals and par- ticularly between clans, after which there should be no reprisal. This is illustrated by a peculiar ceremony among the Iroquois, strongly resembling the scapegoat of the Israelites. A white dog, before being burned at the annual feast, was loaded with the con- fessions or repentings of the people, represented by strings of wampum. The statute of limitations then began to operate. In the Jahvistic version, the passover, an old festival held in the 74 THE POPULAR SCIENCE MONTHLY. spring, was historically connected with the departure from Egypt. The ceremonies are too well known to require narration, but will readily be compared with those of the Indians. Incense. — The use of incense among Indians was the same as among Israelites — i. e., to bring and to please the spirit addressed. A genuine instance among the Iroquois was where tobacco was offered as late as 1882, and in archaic formal language still pre- served, translated as follows : Address to the fire : " Bless thy grandchildren, protect and strengthen them. By this tobacco we give thee a sweet-smelling sacrifice, and ask thy care to keep us from sickness and famine." Address to the thunder : " O grandfather ! thou large-voiced, enrich and bless thy grandchildren ; cause it to rain, so that the earth may produce food for us. We give this tobacco, as thou hast kept us from all manner of monsters." The Dakotas not only burned tobacco in their " buffalo medi- cine " to bring the herds, but often fragrant grass. Other tribes burned the leaves of the white cedar. These forms of incense were sometimes used to entice the inimical spirits, the shaman being supposed to be able, when they had arrived in the form of a bear or some other animal, to kill them with his rattle. Some of the Indians believed that incense and sacrifices generally were to be used only for the spirits from whom they feared harm. They said it was not necessary to trouble themselves about the good spirits, who were all right anyhow. Fetiches. — Among many of the tribes of Indians there is a tri- bal totem (and often several clan totems) which, in later times becoming chiefly symbolic and emblematic, was once used in ob- jective form for the most important religious purposes. Particu- larly, it was carried on extensive warlike expeditions. Adair, who calls it an "ark," describes it as made of pieces of wood, fastened together in the form of a square, to be carried on the back. It was never placed on the ground, nor did the bearers sit on the earth even when they halted. In many other tribes it was a bag of skins and its contents varied, but generally were " blessed " or " sacred " fragments of wood, stone, or bone. Among the Oma- ha it was a large shell, covered with various envelopes, and was never wholly exposed to sight, for that would occasion death or blindness. A custodian was appointed every four years by the old men of the Blackfeet, to take charge of the sacred pipe, pipe-stem, mat, and other implements, which he alone was permitted to handle. The ark of the Israelites was probably derived from the Egyp- tians, who had a real ark which was carried on the shoulders of the priests in processions. When the exodus began, the Egyptian ark for convenience was changed into a chest fitted with staves ISRAELITE AND INDIAN. 75 for bearers. It became the standard of their warring and wan- dering life. In addition to what has been called the ark or tribal fetich, the mystery-bag that each Indian had is to be compared with the Is- raelite teraph, which was a family or tutelary fetich independent of the national worship, and later was the subject of frequent denunciation. It was probably made of carved wood, and was often carried on the person, but was generally held as a house- hold god or domestic oracle. The teraphim markedly resembled the Roman penates. This comparison is explanatory of the statement that neither the Israelites nor the Indians worshiped idols. Its truth depends upon what is considered to be an idol. If the definition is limited to the human form the assertion is true, because their religion was not anthropomorphic ; but fetiches were certainly the objects of worship, the recrudescent forms of which, appearing even in civilization, have been amulets, lucky-stones, pieces of wood and charms. Sabbath. — It is not possible, in discussing the Israelites, to neg- lect the institution of the Sabbath. The four quarters of the moon made an obvious division of the month, and wherever the new moon and full moon are made religious occasions there comes a cycle of fourteen or fifteen days, of which the week of seven or eight days forms half. It is significant that in the older parts of the Hebrew Scriptures the new moon and the Sabbath are almost invariably mentioned together. Among the Israelites, and per- haps among the Canaanites, joy on the new moon became the type of religious festivity in general. There is an indication that in old times the feast of the new moon lasted two days, so that an approximation to regular recurrence of the subdivisions constitut- ing the week was gained. The Babylonians and Assyrians had an institution dividing the month into four parts, by which, on the days assigned, labor was forbidden ; but originally the Israel- ites' abstinence from labor was only incidental to their not work- ing at the same time that they were feasting. "While they were nomads, with only intermittent work, they had no occasion for a fixed day of rest. The new moons were at least as important as the Sabbath until the seventh century before Christ. When the local sacrifices were abolished and the rites and feasts were limited to the central altar, which practically could be visited only at rare intervals, the gen- eral festival of the new moon ceased. The Sabbath did not, but became an institution of law divorced from ritual. The connec- tion between the week of seven days and the work of creation is now recognized as secondary. The original sketch of the deca- logue probably did not contain any allusion to the creation, and it 76 THE POPULAR SCIENCE MONTHLY. is even doubtful whether the original form of Genesis distributed creation over six days. Subsequent history of the Sabbath shows a reflex action be- tween religion and sociology. Religion prevailed against better arrangements for periods of rest. Sociology used religion to get what it could. The Indians reached only the first part of the inception of the Sabbath in the ceremonies of the new and full moon, which were to them of great importance, those of the new moon being most noted. Circumcision. — This, generally regarded as a distinctive mark of the Israelites, is by no means peculiar to them, and is found in so many parts of the world, with such evidences of great antiquity, as to contravene its attribution to them. Its origin is a subject of much dispute. As practiced indiscriminately in infancy, it is perhaps a surgical blunder. It is certain that among the Is- raelites it was not at first a religious rite. The operation was not then performed by the priesthood, but by a secular person of skill, without ceremonials. Afterward it was regarded as an initiatory ceremony, and as such its parallels connected with the sexual organization may be found all over the world, but as a special national distinction the declared object was not attained. Besides the Egyptians, Arabs and Persians, with whom the coincidence might be expected, many tribes of Africa, Central and South America, Madagascar, and scores of islands of the sea, show the same mark, and it has even been found in several of the North American tribes. The sole motive for alluding to this very com- prehensive subject is to correct the popular belief that the custom is peculiar to the Israelites. In this as in many other alleged re- spects they were not " peculiar." ^*«-&- IS THE HUMAN BODY A STORAGE-BATTERY? Br HTLAND C. KIEK. HON. J. W. DOUGLASS, a lawyer of "Washington, D. C, formerly Commissioner of Internal Revenue, after reaching his office one morning, to relieve the pressure on his foot, took off one of his new boots and sat at his work, his legs crossed in the customary legal form, his stockinged foot swinging freely. It happened to swing over the waste-basket, when, to his exceeding surprise, every piece of paper, string, and scrap in that receptacle, as if impelled by a writ of habeas corpus, rose up and clung to his foot. He brushed off the scraps and tried it again, and again that peremptory mandamus or process of attachment seemed to IS THE HUMAN BODY A STORAGE-BATTERY ? 77 issue from his pedal extremity, and again the " poor white trash " of the waste-basket joined issue with the stocking. He was in a condition of excellent health and spirits that morning, and in a mood for experimenting: he removed his remaining boot, and secured a similar result with the other foot ; when, congratulating himself on the fact that he seemed to be a very attractive person, he returned to his work. An incident of this kind, though more startling in its outcome, is related as occurring in the same city more than eighty years ago, in a letter of a United States Senator, Dr. Samuel L. Mitchell. The letter is dated at Washington, March 17, 1802. He says : " A very singular occurrence has happened to General Dayton, of Elizabethstown, one of the New Jersey Senators. He pulled off his stockings of silk, under which were another pair of woolen gauze, just as he was going to bed. The former were dropped on the small carpet by the bedside, and the latter were thrown to some distance near its foot. Electrical snaps and sparks were observed by him to be unusually prevalent when he took off his stockings. He slept until morning, when the silk stockings were found to be converted to coal, having the semblance of sticks and threads, but falling to pieces on being touched. There was not the least cohesion. One of the slippers, which lay under the stockings, was considerably burned. One of the woolen garters was also burned in pieces — the carpet was burned through to the floor, and the floor itself was scorched to charcoal. It was a case of spontaneous combustion — the candle having been carefully put out, and there being very little fire on the hearth, and both of them being eight feet or more from the stockings." Dr. R. D. Mussey, Professor of Surgery in Dartmouth College, in the "American Journal of Medical Sciences" for January, 1838, gives an account of a Mrs. B — , a married lady about thirty years of age, residing in Grafton County, New Hampshire, who gave out sparks and snaps continuously for some thirteen weeks, when this power was entirely lost and did not return again. The discovery of this faculty was a great surprise to the lady, and subsequently caused her some annoyance. Though Mrs. B — wore a silk dress at the time of the commencement of the phenomenon, this was exchanged for cotton and flannel successively without affecting the result ; and the manifestations were found to be due to the lady's own person, and not to the clothing or other con- ditions. Dr. Mussey's account is supported also by Dr. W. Hos- ford, the lady's family physician. Phenomena of this sort, when manifested, do not seem to be confined to any one portion of the human body, though occasion- ally localized. A Capuchin friar is mentioned by Dr. Schneider, whose scalp was a veritable reservoir of electricity. Whenever 78 THE POPULAR SCIENCE MONTHLY. he removed his cowl a number of " shining, crackling sparks " would pass from his bald pate ; and this phenomenon, which was definite and strong while the monk was in good health, continued perceptible after three weeks' illness. The case of Angelique Cottin has been frequently referred to. She was a French peasant girl, fourteen years of age, and pos- sessing excellent health at the time her singular powers were dis- covered. She resided in the Commune of La Perriere, department of Orne, and with three other young girls was engaged in knitting ladies' silk-net gloves. Suddenly the oak weaving-frame was thrown down. The girls put it up ; and almost instantly it was again upset. It was soon discovered that, whenever the girl Cot- tin touched her warp, the frame was agitated, would move about, and then, without apparent cause, be thrown violently back. Sub- sequently chairs, tables, lighted fire-wood, brushes, books, tongs, shovels, scissors, and other metallic articles were all set in mo- tion whenever this girl approached them. The girl was very im- perfectly educated and her friends were of limited intelligence, so it was not remarkable that, in 184G, such phenomena should be attributed to sorcery. The case was investigated by a number of scientific gentlemen, including M. Arago, who were shocked, as well as startled, and gave surprising accounts of her powers. Some time after, however, she was taken to Paris and examined by the savants of the Academy, and nothing of a surprising char- acter was discovered. She had simply lost the power she formerly possessed. The manifestations of Miss Lulu Hurst, of Georgia, will be recalled. A tall, large-boned, well-developed, good-looking coun- try girl, reared on a farm, without any knowledge of occult forces, and among people almost wholly uninterested in scientific sub- jects, suddenly seems to possess a peculiar force, and the furni- ture begins to manifest unusual qualities when Miss Hurst is present, phenomena occurring not unlike those attributed to the French girl of La Perriere. This power, which was considerable in the outset, gradually waned, until her public exhibitions were quite unsatisfactory. The writer was one of the committee who, on her first appear- ance at Wallack's Theatre, New York, had opportunity to inves- tigate Miss Hurst. One test was as follows : Three gentlemen, among whom was a professor of athletics, each using both hands, held a billiard-cue above their heads in the air ; Miss Hurst, by placing her hands flat on the top of the cue, brought it down with- out apparent muscular effort. At that time all power of repelling articles without contact seemed to have left her ; but her success in collapsing umbrellas held by a reporter, and in lifting and re- pelling chairs by lightly touching them, was quite extraordinary. IS THE HUMAN BODY A STORAGE-BATTERY ? 79 During these performances she kept up a low, nervous giggle, and did not seem especially fatigued at the close. Other Georgia women developed similar powers about the same time, or shortly after Miss Hurst's peculiarity became known. Miss Mattie L. Price, living in the same neighborhood, was one of these, and Mrs. C. F. Coleman, wife of the superintendent of the Atlanta cotton-factory, was another. These accounts all appear the more credible from the fact that an examination proves every human being, and in fact every animal organism, to be in some degree a producing battery of electricity. Du Bois-Reymond, Nobili, and Matteucci have, by numerous experiments, determined the existence of electric cur- rents in the nerves and muscles ; by means of delicate tests, Bec- querel has detected electricity in the capillaries and other minute tissues ; Engelmann, Volkmann, Hermann, and others, have ex- perimentally determined something of the conditions under which various tissue-currents are manifested ; and it is more than proba- ble that this subtile fluid is being constantly generated in the processes of digestion, circulation, respiration, and secretion. The electric fishes — the torpedo, the silurus, the gymnotus, and the ray — are the only animals, it is true, possessing a special appa- ratus for the production of electricity ; yet the cell-structure and disks of their batteries have been developed from ordinary cells and tissues common to animal life. Other animals sometimes evince like powers. An acquaintance of the writer, some years ago, in California, came upon a splendid specimen of rattlesnake which he determined to capture. With a forked stick he suc- ceeded in pinning his snakeship to the ground just as he had reached a hole. The snake seemed to be securely caught, but with a convulsive effort he not only entered the hole, but gave my friend an electric shock which he recalls as one of the strong- est he ever received. We are largely ignorant of the conditions necessary to the storage of this force in the human organism, but good health seems to be one. When their power is dissipated by repeated shocks, electric fish exhibit all the lassitude of weary human be- ings. The writer once handled a gymnotus, in Fulton Market, whose shock was hardly perceptible; yet, when vigorous, they are known to kill horses and mules by their powerful discharges. It is said that any person in good health may convert his lower extremities into electric batteries, by wearing two pairs of silk stockings, preferably a black pair over white. After wearing them but a short time and removing them together, an attempt to sepa- rate the two colors will manifest a resistance of several pounds. Atmospheric conditions have much to do with electricity in the body. In several cases, notably those of Angelique Cottin 80 THE POPULAR SCIENCE MONTHLY. and Mrs. B — , of New Hampshire, this power was first discovered during the imminence of a thunder-storm. Human electrometers are sometimes met with. A young man named William Chap- man, of Providence, R. I., was stunned by the shock of a stroke of lightning which struck his father's house. The current passed through his body and went out at his right heel, which was pain- ful for some time afterward. On every occasion of a thunder- storm since then he feels, hours before the time, a tingling pain in the heel. Young Chapman would be a valuable acquisition to the Signal Service as a portable electrometer, and, if he can do as well as he is said to have done on certain occasions, he would be ahead of any device that science has yet lighted upon to foretell an electrical storm. A remarkable instance of the salutary effects of atmospheric electricity on the human body is told by the Wolverhampton cor- respondent of the London " Times." He states that during a thunder-storm a collier named Bates, who had lost his sight through an accident, was being led home, when a flash of light- ning was reflected on the spectacles he was wearing to conceal his disfigurement. After the peal of thunder which followed he complained of pain in his head. The next moment, to his sur- prise, he found that he had regained possession of his eye-sight. The occurrence caused considerable excitement in the locality. Since the date of Galvani's discovery, there have been many persons sufficiently bold to assert the identity of electricity and life. Even before that period, the observance of electric phenomena in man had been a subject of popular interest. In his " History of Electricity," Priestley relates that drawing a spark from a liv- ing body " makes a principal part of the diversion of gentlemen and ladies who come to see experiments in electricity." Doubt- less the diversion was not lessened by the fact that the " electrical kiss " was a favorite form of the experiment. The excitement in Paris, Edinburgh, and other cities, follow- ing the application of galvanic electricity to dead bodies, was of a very startling character, many supposing that the secrets of life were about to be yielded up by this wonderful fluid. Bonaparte, it is said, after witnessing experiments in voltaic electrolysis, remarked to his physician, Corvisart : " Here, doctor, is the image of life ; the vertebral column is the pile, the liver is the negative, the bladder the positive pole." Though much has been discov- ered since that statement was made, but a modicum of the truth probably is known. Perhaps the developed man of the future, in his physiological relations to the universe, may exemplify the magnet, whose forces are exerted constantly as received without seeming detriment to its substance. RESPONSIBILITY IN MENTAL DISEASE. 81 RESPONSIBILITY IN MENTAL DISEASE.* By Sir JAMES CRICHTON-BROWNE, M. D. I CAN not pretend to summarize what has been written or said about insanity and crime during the last forty years, or a fourth of that time. All that I propose is to submit a few obser- vations which have occurred to me on the following points : (1) on the insufficiency of the definition or test of insanity at present accepted and acted on in courts of law in this country, and on an amended test which would commend itself to medical experience ; (2) on the value of expert testimony in establishing the existence and nature of insanity in courts of law; and (o) on a practical step toward the reconcilement of medical and legal differences of opinion on questions of insanity and crime. What is the law of England with reference to insanity as an excuse for crime, and how far is that law reasonable and in accord with the conclusions of medical science ? As to what the law is, there can not be much doubt, for every judgment delivered in cases in which the plea of insanity has been set up since 1843 has been founded on the answers then returned by the judges to the questions put to them by the House of Lords during the ground- swell of the McNaghten case. The gist of these answers runs : " That to establish a defense on the ground of insanity, it must be clearly proved that at the time of committing the act the ac- cused was laboring under such a defect of reason from disease of the mind as not to know the nature and quality of the act he was doing, or if he did know it that he did not know he was doing what was wrong." Now, it is obvious that under this ruling, if I may call it so, are included a .large number of cases of insanity. Under it would stand excused the raving maniac who does not ap- prehend the nature or quality of any act, the idiot who is in the same predicament, the fatuous person who can not foresee the consequences of his acts, and the victim of delusions, when these are of such a character as would justify homicide were they be- liefs entertained by a sane man. But it is, and always has been, equally obvious to medical men that this ruling excludes a con- siderable proportion of cases of insanity in which moral as dis- tinguished from legal irresponsibility exists, and that it is faulty in founding the test of insanity on knowledge or an intellectual state while it ignores states of the emotions and will, which are always more influential on conduct than intellectual states, and bulk far more largely in insanity. The test of insanity which * Abridged from a lecture delivered to the College of State Medicine. vol. xxxvi. — 6 8z THE POPULAR SCIENCE MONTHLY. commends itself to medical men was never more clearly and suc- cinctly expressed than by Lord Bramwell when in the Dove case he asked, " Could he help it ? " Could he or she help it ? That is the real practical question at issue in every case in which the defense of insanity is set up. Was the lunatic free to choose, or under the duress of disease ? Was his will incapable or inept ? But Lord Bramwell and those who think with him argue that it is sufficiently proved that the lunatic could help it if he knew the nature of his act — viz., that it was killing ; the quality of his act — viz., that it was a crime ; and also that it was wrong in the sense of being forbidden by law. Whereas medical men, almost without exception, maintain that a lunatic may be able to know and express the nature and quality of an act and its wrongness, and yet be as unable to resist doing it as he is to abstain from j limping under a smart electric shock ; and that knowledge of the nature and quality of an act and its wrongness is not in the regions of pathology any measure of will-power. And not only medical men, but judges, have perceived this. The late Lord Chief -Justice Cockburn said, " The power of self-control, when destroyed or suspended by mental disease, becomes, I think, an essential element in the question of responsibility." And Mr. Justice Stephen has said, " It ought to be the law of England that no act is a crime if the person who does it is at the time when it is done prevented by defective mental power, or by any disease affecting his mind, from controlling his own conduct, unless the absence of the power of self-control has been produced by his own default." This statement of the law, which has been verbally amended by Dr. Bucknill, really covers all that medical men have ever contended for, and, having received it from so high an au- thority, it is their duty to do their best to secure its acceptance, and provide trustworthy tests of loss of self-control. Now, impairment of will, or loss of self-control, more or less pronounced, is, according to medical men, the first, last, and uni- versal element in insanity, and ranges from a trifling reduction in the check-action which we exercise on the ordinary currents of thought and feeling down to paralysis of the sphincters. Dissolu- tion— and insanity is dissolution — implies a reversal of evolution, and in insanity we have, as Dr. Hnghlings Jackson has taught us, a process of undevelopment, or taking to pieces, in the highest centers, which are the crown or climax of nervous evolution. In it we have " a descent from the least organized, most complex, and most voluntary, toward the most organized, most simple, and least voluntary." There is in every case of insanity impairment of vol- untary control, and as a consequence of this there is more or less license given to those lower mental functions which are during sanity under voluntary control, and which become then overactive, RESPONSIBILITY IN MENTAL DISEASE. 8.3 tlieir overactivity being expressed in delusions,, hallucinations, wild and whirling words, and extravagant actions. When our attention is withdrawn — as, for instance,, when we have dropped into a reverie or are just falling asleep — a sound that might have made us turn our heads, if on the alert, will cause us to start violently ; and when in insanity volition is impaired, sen- sations that would have been almost unnoticed in health stir up morbid feelings. Did time permit, I think I could establish that affinitive sights, sounds, smells, tastes, and surface impressions, as well as organic sensations, play a larger part than is generally supposed in the induction of morbid impulses when the regulating brain-centers are weakened. Many sane persons have experienced horrid promptings when standing looking over a precipice or gazing at a passing train, and among the insane the glitter of a knife or the crackling of a fire will sometimes evoke suicidal or homicidal impulses which but for it might have remained dormant. Will is the link between feeling and action, and when it is im- paired it ceases to be available to prevent the transmutation of the energy of feeling into the energy of motion. And here we have an explanation of the utter inadequacy of the motives that constantly lead to insane crimes. There is no check-action ; there is an ab- breviation of that pause that gives time for foresight and reflec- tion. " Must give us pause ! " says Hamlet when on the brink of suicide — time to summon up the forces of rational resistance. Man is a hesitating animal. The whole system of Zoroaster hinges on the fact that everything noxious and evil in creation is the work of Ahriman, an independent power, whose wickedness depends on the fact that he acts before he thinks ; whereas Ormuzd, the good spirit, thinks before he acts. And madmen may in many instances be distinguished from sane men in the same way. The impul- sive madman acts before he thinks ; feeling is translated into action with reflex precipitancy, with an abbreviation of that time interval between stimulus and response which can now be sub- jected to experimental measurement ; in the absence, therefore, of all restraining considerations, and in a violent and disproportion- ate manner. I have known an epileptic to kill his attendant, beat- ing his head into jelly, because he had prevented him from taking his daily walk. I have known another epileptic hang himself because a smaller portion of bread and butter had been served out to him than to his companions ; and, in the recent case at Weston- super-Mare, the lad Hitchins shot his sister because of some tri- fling slight which she had put upon him. In all such cases a mo- mentary irritation, a natural feeling of chagrin, such as we all feel when thwarted or disparaged, instead of being inhibited in its nas- cent state when inhibition is most powerful, so that the reaction to it may be reduced by deliberation to rational proportions, is, by the 84 THE POPULAR SCIENCE MONTHLY. diminished resistance of the will and the consequent overaction of the lower centers, permitted to become fixed or to express itself in a grossly exaggerated manner. That voluntary power is invariably impaired in insanity is not perhaps evident to those who have not looked closely into the matter. Is it not true, it may be asked, that some insane persons exhibit extraordinary fixity of purpose and persist in some course of conduct — as, for example, the refusal of food with dogged ob- stinacy ? That is so, but insane obstinacy is no more an indication of voluntary power than is the late rigidity of a paralyzed arm. That state of late rigidity in which the arm could not be stretched without being broken betokens that certain lower centers have been cut off from intercourse with higher ones and are undergoing degeneration ; and so the unreasonable obstinacy of lunatics in insane conduct merely indicates that certain mental functions have escaped the regulation of volition, which is enfeebled, and are acting in an irregular and self-willed manner in consequence. No doubt in all cases of insanity a certain amount of volitional power is retained, and this may in certain cases be effectual to some extent over the morbid mental manifestations. There may be con- tributory negligence on the part of a lunatic, just as there may be on the part of an invalid. Prof. Ruble, of Bonn, recommends the birch-rod and shower-baths in certain cases of chronic vomiting, and asserts that children often die of a bad bringing up, and adults because they can not, when ill, make up their minds to do what is right and omit what is hurtful ; and Niemeyer quotes with approval the dictum of the wife of a Prussian general, a most determined woman but a tender mother, that whooping- cough is only curable by the rod. But no one in this country would now sanction such heroic treatment, or believe that any- thing but evil could come from such stringent appeals to a mere remnant of will in its corporeal relations ; and so it would be dan- gerous in cases of insanity, in which will is obviously and seriously involved in its mental relations, to infer that what survives of it might, if put forth, have prevented a criminal act. In insanity, in which the mental movements are typically involuntary, but yet susceptible of some control, we must not expect of the patient what is beyond his strength — the habitual suppression of his morbid impulses. The criminal act of a lunatic is sometimes so alien to his healthy disposition, or so clearly motiveless, that we have no hesitation in concluding that his true will must have been in abeyance when he fell into it. At other times it follows upon mental struggles which he has himself described, and asked help in, previous to its commission, and is therefore clearly but the climax of a pathological process signifying the overthrow of the will. And at other times, again, it is associated with mental RESPONSIBILITY IN MENTAL DISEASE. 85 and bodily symptoms which, our experience has taught us, corre- spond with complete paralysis of will. A lunatic may unquestionably commit a crime under ordinary motives. It can not be contended that every mental oddity and isolated delusion is to put a man beyond the pale of the law, but it is to be remembered that a really isolated delusion is a rarity, and that most delusions are but local manifestations of a consti- tutional vice, involving weakening of will. Most lunatics are, it has been said, mad to their finger-tips ; and what appear to be their sane acts are generally more or less tinctured with insanity. I can not pause here even to sketch the several stages of men- tal dissolution, but I would suggest that there are practically three levels of these in connection with lunatic crime. They are — the ideational level, the impulsive level, and the automatic level. On the first, the ideational level, the criminal act is committed under the influence of an insane motive or a delusion or hallucination, with consciousness at the time and remembrance afterward of all that has taken place, but in consequence of a diminution of inhibi- tory or resisting power. On the second, it is committed under the stress of a sudden and irresistible impulse, which is often a reversion to a mere animal instinct, with vague or imperfect con- sciousness at the time, obscure remembrance afterward, and under a still more grave paresis of inhibitory power. On the third, it is committed under the influence of accidental or reflex suggestion, without consciousness at the time or remembrance afterward, and during the complete abrogation of inhibitory power. As illustra- tions, I may mention on the first level the case of a man who kills his friend with elaborate preparation to spare him suffering, be- cause he has been told by the archangel Michael that the death of that friend is necessary to the extinction of Freemasonry, which is the curse of the human race, and who afterward describes the homicide' in detail, and with evident pride and satisfaction; on the second level, the case of a puerperal woman, who, seeing a glitter- ing knife by her bedside, suddenly cuts her baby's throat, without afterward having any clear recollection of the event or being able to say why she did it, although the knowledge that she had done it fills her with grief and remorse ; and on the third level, the case of an epileptic, who, while recovering from a fit, kills whoever happens to be nearest to him, while still unconscious, and who retains afterward no trace of recollection of the tragedy. It seems to me that nothing has more retarded an approach to a just appreciation of the relations of responsibility and disease than the assent, tacit or explicit, generally given to the dogma that the existence of insanity is a question for men of common sense — a question which they are quite as capable of deciding as medical men or experts. The late Lord Shaftesbury, who, by his 86 THE POPULAR SCIENCE MONTHLY. philanthropic labors, conferred such signal benefits on the insane, did some disservice to medical jurisprudence when he lent the weight of his authority to this doctrine, and maintained that " persons of common sense, conversant with the world, and hav- ing a practical knowledge of mankind, brought into the presence of a lunatic, would in a short time find out whether he was or was not capable of managing his own affairs " ; and the late Sir Benja- min Brodie erred, I think, still more grievously when he said : " It is a great mistake to suppose that this is a question (unsound- ness of mind) which can be determined only by medical practition- ers. Any one of common sense, and having a fair knowledge of human nature, who will give it due consideration, is competent to form an opinion on it ; and it belongs fully as much to those whose office it is to administer the law as it does to the medical profession." Now, it may be admitted that there was a time when medical science was in its infancy, when the functions of the brain were unknown, and when only metaphysical explanations of insanity were attempted, at which the existence of insanity in any given case might have been as correctly determined by plain, unsophis- ticated men as by pretentious empirics. Further, it may be grant- ed that there are an immense number of cases of insanity in which the symptoms of the disease are so obvious and external, that spe- cial skill, although requisite to interpret these symptoms, explain their causes, predict their results, and prescribe treatment, is not necessary to their identification. But, beyond all this, there are, it must be maintained, cases of insanity of so obscure and subtle a nature that they can only be properly identified by those who have made themselves intimately acquainted with the functions of the nervous system in health and disease, and who have by ex- perience come to appreciate the significance of combinations of mental phenomena and of concomitant bodily variations, which would appear meaningless to the uninitiated. The fact is, that practically the utility of expert testimony in insanity is acknowledged, and it is difficult to understand how it could be otherwise, for all who have made only a superficial study of mental diseases must perceive that there are in them little sign s and symptoms, perversions of thought and derangements of bod- ily functions, which would altogether escape the notice of com- mon sense, but warrant an expert, founding on his experience, in proclaiming that the will is reduced to impotency, and that the lunatic can not control himself. There is something in the ap- pearance, manner, and mode of expression of lunatics of various classes which would pass unnoticed by common sense, but be characteristic to those who had been accustomed to watch them narrowly. There are styles of morbid thought which can not be RESPONSIBILITY IN MENTAL DISEASE. 87 simulated. There are latent or concealed delusions which start into view when the appropriate spring is touched. There is the order in disorder of dissolution which can not be imitated. There are types of delusions and hallucinations which are easily recog- nized. And, above all, there are physical signs of disorder of the brain and nervous system which correspond with certain stages in the degradation of will-power. To the expert witness in cases of insanity and crime these questions should, it seems to me, be put : Was the prisoner insane at the time when he committed the act of which he is accused ? Was his insanity of such a nature and degree as to deprive him of control over his conduct ? What are the grounds upon which you have formed these opinions ? It would then remain for the jury, aided by the judge, and with the assistance of other experts if necessary, to decide on the validity of the grounds stated and on the weight to be attached to the opinions expressed. Expert testimony, to be of the highest value, ought of course to be founded on an examination, or, better still, on repeated ex- aminations, of the accused, made as soon as possible after the per- petration of the crime. But insanity is a chronic disease ; and even when the expert has not seen the alleged lunatic until some time after his crime, he may still be able to say whether in the course of a disease still existing, or of the recent existence of which there are traces, such a criminal act was likely to crop up as part and parcel of the disease; and whether it is consistent with his experience and with the history of the act that the ac- cused could not help it. When the crime was committed during a temporary paroxysm of madness or during an attack from which recovery has taken place before the examination has been ordered, it may still be possible for an expert to say whether the symptoms described to him form a true picture of mental disease or are only a spurious copy, and whether any wreckage still marks the course of a nerve-storm. Sometimes it will be impossible for an expert to make up his mind either one way or the other, and then it is his duty plainly to say so. And now I have a practical suggestion to offer which would, if adopted, I venture to believe, do more to reconcile the great professions of law and medicine on the questions at issue between them respecting insanity and crime than any prolongation of those elaborate and sometimes highly spiced logomachies in which they have both indulged in the past. What is wanted is a series of skilled and sustained observa- tions on homicides who have escaped punishment on the plea of insanity, made by competent and unbiased authorities, couched in language understanded of the people, and published from time to time. And, in order that such a series of observations may be 88 THE POPULAR SCIENCE MONTHLY. pursued, I would propose the appointment of a committee or com- mission, composed in equal parts of lawyers and medical men, whose duty it should be to visit the asylums as often as they might deem expedient, to examine individually all patients de- tained there who have been charged with murder, and also the officers of the asylums, and their case-books and registers, and to report annually on the mental condition of every such patient, with special reference to the circumstances of the crime of which he or she was accused, and the evidence adduced at his or her trial, adding such remarks on the relations of insanity and crime, and such recommendations for alterations' of the law, as their ex- perience may suggest to them. Looking forward to such reports, the faithful scientific witness would speak with confidence, assured that his evidence, although it might appear strained at the time, would be confirmed by events ; while the pseudo-scientific witness, if there be any such, who is led into the box by a thirst for notoriety or a spurious phi- lanthropy, would pause before committing himself to statements which might rise up in judgment against him in a very dam- aging and persistent way. And there can be no impropriety in alleging that such reports would ultimately prove useful to judges and counsel. Beyond this, the deliberations of such a commission would conduce in some degree to an agreement between lawyers and doctors on the question of insanity and crime. It is in the atmos- phere of the courts of law that differences between them spring up, differences which in private conference speedily dwindle away. It is about theoretical definitions and verbal distinctions that they contend ; and wherever they are brought together in actual con- tact over a case anywhere save in a court of law, the lawyers with striking aptitude adopt the scientific standpoint, and harmony results. — TJie Lancet. **♦ THE LUCAYAN INDIANS. By Prof. W. K. BROOKS, OF JOHNS HOPKINS UNIVERSITY. IN three years the world will unite in celebrating the four hun- dredth anniversary of what, from our point of view, is the grandest and most important event in history, the landing of Co- lumbus ; but in our consciousness of its profound significance, are we not in danger of forgetting that the Spaniards discovered Amer- ica in the way that pirates discover a vessel with a helpless crew ? While no one can doubt that the world, as a whole, has been benefited, there is reason to question whether any of the islands which Columbus himself discovered have profited by the change. THE LUG AY AN INDIANS. 89 Hayti is almost completely in a state of revolting and hopeless savagery, and recent writers assert that Jamaica is rapidly trav- eling the same road. The condition of Cuba is by no means en- couraging to her friends ; and in the Bahamas, abandoned home- steads, costly villas tumbling to ruins, roofless walls, and fields and plantations converted into tropical jungles, testify to any- thing but prosperity. The population of the Bahamas is less to-day than it was on the day Columbus landed, and it is not increasing. He found the Bahamas in the possession of a prosperous and happy people who called the islands the Lucayas, and themselves Ceboynas. Twelve years afterward every soul of this population of more than forty thousand men, women, and children had per- ished in a strange land under the lash of the slave-driver; the race was blotted off the face of the earth, and the only impression which has been left upon our civilization by those who first wel- comed it to this continent is a single word, which, together with the luxurious article it designates, has spread over the whole earth. The Ceboynas gave us the hammock, and this one Lucayan word is their only monument. Nowhere in all the black pages of history is there a darker tragedy than theirs ; and while it is eminently proper that we should pay all homage to the transcendent genius and noble na- ture of the great admiral, and that we should celebrate with all pomp and pride the miraculous growth of our own civilization, does it not also become us to commemorate in some way, at the same time, the story of the unhappy and forgotten Ceboynas, to whom the discovery had a still more profound significance ? How intensely interesting, just at present, is any addition to our knowledge of the other party to the transaction ! The writer has recently spent two seasons in zoological research in the Baha- ma Islands, and has been able to learn a few facts, which are new to the science of anthropology, relating to the bodily structure of the long-lost Ceboynas, and thus to contribute toward the per- petuation of their memory. There is not much intrinsic interest in a few fragments of hu- man bones, but the Ceboyna skull which stands upon my table as I write gives life and vivid reality to the familiar story in the first chapter of my school history, and calls up in all its details with startling clearness the drama of the Bahama Islands. To most of us these islands are little more than dots upon the map, but, small and sterile and unimportant as they are, they form one of the fairest landscapes upon earth, for they present all the conditions which are most favorable for intensity of color of earth and sea and sky. Under the combined influence of white soil, intense sunlight, and perfect purity of air and water, they 9o THE POPULAR SCIENCE MONTHLY. glow with the sparkling colors of jewels. The hot air is loaded with moisture to the saturation-point, like that of the deep, shady recesses of a rocky glen on the edge of a waterfall ; but the islands are also as wind-swept as a mountain-top, and the air is absolutely pure, for the ocean breeze brings with it no smoke nor dust, no pollen nor vegetable refuse, nor anything whatever except pure, moist, warm air. As the saturated sea-breeze blows over the thousand islands of the archipelago, the slight difference between the temperature of the changeless ocean and that of the variable land, which heats quickly in the daytime and cools quickly at night, manifests itself by the formation of great, snow-white banks of summer clouds which are as characteristic of the Bahama hori- zon as the water itself or the deep, pure blue of the sky between the clouds. The islands stand on the extreme edge of a submerged abyss where the surface falls as suddenly and to as great a depth as it does from the summit of the Andes, and the unfathomable wa- ter of mid-ocean is only a few miles away. Some of the out islands are only two miles or so from water more than two miles deep, and the currents which sweep through the sounds and around the islands at each turn of the tide are absolutely pure, and they have the intense color which is found in mid-ocean, or the melted ice of glacial lakes, or in the center of the rocky basin of Lake Superior. In great depths this color is a pure, vivid sap- phire blue, darker but more transparent than the blue of the sky. In the shallow sounds, where the intense sunlight is re- flected back from the chalky bottom, it glows like a surface of beryl with an intense green lustre totally unlike anything which is met with in other waters, although the center of the Horse- shoe at Niagara would be very similar if it plunged over a ledge of white marble under the light of a tropical sun. All these influences combine to give a degree of intensity and vividness which can not exist in a continent to ail the colors of a landscape which is wrapped in perpetual spring. Under their dome of blue sky and snowy clouds the Isles of June, in their setting of sapphire, are buried under a mantle of verdure so dense and lux- uriant that the vegetation thrives as if in a hot-house, and, aban- doning the rocky and sterile ground and contenting themselves with the warm, moist sea-breeze, not only the mosses and ferns and orchids and bromeliads, but large trees as well, grow tier above tier, climbing over each other's heads in their efforts to escape the struggle for existence and to obtain air and sunlight and standing-room. Who can wonder that, when Columbus found himself in this enchanted fairy -land after the changeless monotony of mid-ocean and all the anxieties of his long voyage into unknown waters, he THE LUG AY AN INDIANS. 91 should have been most profoundly impressed by its beauty, for no- where on earth can we find a fairer land than these Isles of June. The exciting occupations incident upon his arrival left him little time for writing, but he faithfully jotted down day by day in his log-book in short, crisp sentences which even now are full of graph- ic interest, the impressions which were still fresh upon him. The United States Coast Survey has recently done good service to his- tory by the publication of an English translation of this rare and almost unknown document, and the extracts in this paper are from this translation. After he set sail on the second day, he says that he saw so many islands that he could not decide to which one he should go first, and the men he had taken told him by signs that they were innumerable. On the fifth day he writes of the island which he named Isabella : " There was in it twelve leagues, as far as a cape which I called Cape Beautiful, which is in the west, and so it is beautiful, round, and very deep and free from shoals ; at first it is rocky and low, but farther in it is a sandy beach, as it is along most of our coast. The island is the most beautiful thing I have seen ; if the others are very beautiful, this is still more so ; it has many trees, very green and Very large, and this land is higher than that of the other islands I have discovered, although it can not be called mountainous. Yet gentle hills enhance with their contrasts the beauty of the plain, and there appears to be much water in the middle of the island. Northeast of this cape there is an extensive promontory, and there are many groves very thick and very large. I wished to anchor off it in order to land, and visit so handsome a spot, but it was shallow and I could not anchor, except far from land, and the wind was very favorable to come to this cape, where I am now anchored, and which I have called the Cape Beautiful because it is so ; and so I did not anchor off that promontory, because I saw this cape so green and so beautiful, as are all the other things and lands of these islands, so that I do not know to which to go first, nor do my eyes grow tired with looking at such beautiful verdure ; and when I reached this cape the odor came so good and sweet from flowers or trees on the land, that it was the sweetest thing in the world." Of the Island of Fernandina, he says (October 16th) : " The island is very green and level, and exceedingly fertile. ... I saw many trees whose shape was very different from ours, and many of them which had branches of many kinds, although all growing from one trunk, and one branch of one kind and another of another kind, and so different that the diversity of the kinds is the greatest wonder of the world — for instance, one branch had leaves like those of cane, and another like those of a mastic ; and thus on a single tree there were five or six of these kinds, and all 9 2 THE POPULAR SCIENCE MONTHLY. so different ; nor can it be said that they have been grafted, because these trees grow wild in the field and nobody cares for them. " The fishes here are so different from ours that it is a wonder. Some look like cocks of the finest colors in the world, blue, yellow, red, and all colors, and others variegated in a thousand fashions ; their different hues being so exquisite that nobody can contem- plate them without wondering, and feeling great delight in seeing them. There are also whales here ; but on shore I saw no beasts whatever, save parrots and lizards." • Columbus found all these islands much more thickly inhabited than they are to-day, by a race of people who called themselves Ceboynas, although his misconception as to the nature of his dis- covery led him to bestow on them the name by which all the ab- original inhabitants of this continent are now known. As they had very few artificial wants, and were able to live without forethought or care in a land which knows no change of sea ms, where the harvest ripens without attention, and a tempt- ing fish for the day's dinner can be picked out and speared as if it floated in the clear water of an aquarium, they were totally igno- rant of much that the Spaniards regarded as essential for man, and Columbus, mistaking simplicity for destitution, makes the entry in his log-book that he " thought them to be a very poor people." It is true that, except for the " one who wore in his nose a piece of gold of the size of half a castellano, on which were letters," he found no indications of the wealth of India ; but before he had been a week in the New World he discovered three luxuries which have been warmly welcomed by the whole civilized world. On the third day he enters in his log that " the men I sent for water told me that the houses were well swept and perfectly clean, and that their beds and coverings looked like cotton nets, which they called liamacas " ; and within a few days, as he extended his explorations to the neighboring Antilles, he met with cigars and chocolate. Poor the Ceboynas might be in the matter of useless clothing and arms, but a race which could doze idly in hammocks, under the blue sky, in the warm sea-breeze, idly puffing their Havana cigars, as they gazed out on to the flashing water and waited for their crops to ripen, were not completely destitute and squalid. Civilized man might well covet even a harder life than that of the natives of the lovely Lucayan Islands before the dis- covery, but every school-boy knows the rude awakening which the peaceful Ceboynas soon received. Two years ago I enjoyed the delights of a long cruise, in the schooner which carries the mails, through the calm, landlocked sounds which thread in all directions the mazes of the archipelago, and the gentle but unfailing breeze bore me on day after day, THE LUC AY AN INDIANS. 93 while new beauties rose up and unfolded themselves before me as the islands I had passed dropped down toward the horizon behind me and faded away, until there stole over me the feeling that the whole might be some fairy landscape traced by fancy in the sum- mer clouds, and that if I closed my eyes for a minute I might find it all dissolving into air. As I passed the little inlets, with their lines of white breakers, and beyond them the deep blue of the open ocean fading in the distance into the lighter blue of the sky ; or, as I leaned over the rail while the vessel slipped on as if it were hung in mid-air ; as I watched the gaudy fishes darting over the white sand many fath- oms below, or caught glimpses into the deep dark caves between the great, dome-like coral-heads which swept up in smooth curves from the depths almost to the surface, and overhung cool grottoes hung with gorgeous anemones and sea-fans and sea-feathers, among which innumerable animals in an endless diversity of strange forms could be dimly seen as the vessel slipped by ; as I drifted on day after day, and passed one charming spot after another, only to find still more beauty beyond, I could not escape the thought that in this enchanted land of beauty which no brush could paint, where every prospect pleases, man has been unuttera- bly vile, and this not the heathen in his blindness, but the con- queror who, as old Bernal Diaz quaintly but frankly puts- it, " Took his life in his hand that he might give light to them who sit in darkness, and satisfy the thirst for gold which all men feel." Less than fifteen years after the discovery the forty thousand Ceboynas were gone, and the Lucayas were left desolate. For nearly two hundred years every one of these thousands of lovely islands was abandoned to the parrots and lizards, and, except for the visits of Ponce de Leon, in his search for the magic fountain, and an occasional English sailor, no boat moved through these quiet sounds; until at last the peaceful islanders who, as Coumbus writes to Queen Isabella, were the best people on earth, and loved their neighbors as themselves, were replaced by a new population, and the banner of the Jolly Rodger gathered here, from the ports of Europe, the worst human scum which civilization has ever produced. Who could cruise through this earthly paradise without meditating upon the fruit of our civilization as it has here devel- oped itself ? While Columbus had none of the vices of lesser men, he felt bound to fulfill his promise to enrich those who had aided him ; and on his first Sunday, October 14th, only two days after his landing, the gentle influences of the Sabbath in this strange and beautiful land moved him to commit his impressions to writing, and, while his pen overflows with the delights of the New World and the loveliness of the people, he enters in his log that he is 94 THE POPULAR SCIENCE MONTHLY. keeping a keen watch for a place to build a fort ; for, he says, " In- asmuch as the people are perfectly defenseless, and totally unac- quainted with arms, a force of fifty men could keep them captive in their own island and make them do whatever might be de- sired/' in case the king might not wish them all taken to Spain as slaves. As he found no gold, except the nose-ornament, worth about a dollar and a half, which the owner refused to barter for glass beads, Columbus soon left the Lucayas, and for a few years they were forgotten. By an accident hardly less probable than the discovery of a new world, he soon actually found rich gold- mines in Hayti, and for a time the Spaniards forgot their de- sire to give light to them who sit in darkness, in their eager- ness to slake their thirst for gold. They did not, however, forget the cotton nets of the Ceboynas, and they soon discovered, as all white men in the tropics do, that it is much easier to lie in a ham- mock puffing a cigar, and to sip chocolate as the days slip by, than to dig for gold, and they then bethought themselves of their duty to enlighten the darkness of the heathen natives of the Lucayas. The king at once perceived the importance of bringing these people under Christian influences, and in 1509, or less than eleven years after the discovery, he issued an order for the deportation of the whole population of the Lucayas to New Spain, and the work of conversion was at once vigorously instituted with the aid of blood-hounds. For a time the Spaniards seem to have regarded the Antilles as an inexhaustible slave-quarry, and to have thought it cheaper to replenish their exhausted stock of slaves than to care for those they had. They soon found, however, that it was not so easy as Columbus had thought to make the Ceboynas " do what- ever might be desired " ; and while the people who had never labored for themselves were powerless to escape slavery, they resisted to the death all the efforts of the Spaniards to profit by their labor. So relentless were the conquerors, and so determined and hope- less the captives, that the unhappy slaves perished by wholesale in the mines of Hayti, under the lashes of their drivers and the steel swords which were often broken over their obstinate heads ; and even now the mind recoils from the contemplation of the few facts regarding the fate of the Lucayans which history has pre- served. As an illustration, Las Casas gives, among others, the case of one Spaniard who, three months after he had received three hun- dred Lucayan slaves, had less than thirty left alive. For a short time this destruction was made good by fresh importations, but the supply was soon exhausted. All the islands were left deso- THE LUCAYAN INDIANS. 95 late, and the Lucayan race was as if it had never been. The ham- mock, the first gift of the New World to civilization, is their only monument, and the word the sole remnant of their language. Columbus says that, on Saturday, October 13th, the second day, " A great crowd came, each bringing something, giving thanks to God, and entreating or beseeching us to land. We understood that they asked us if we had come down from heaven " ; and be- fore the children, who were led to the beach to welcome the celes- tial visitors who had been borne to them on white wings out of the blue dome which bounded their world, had grown to man- hood, they perished, with all their race, in a foreign land. Where shall we find a sadder story than this ? The evil was done long ago ; there is now no remedy ; but as the recollection thrills our pulse, and our generous sympathies are awakened, how eagerly do we ask the question : " What manner of men were the Lucayans ? What were they like ? " These questions I am now able to answer, at least imperfectly, and the skull which is here figured once belonged to a person who may possibly have been among those who welcomed Columbus. Like all coral islands, the Bahamas abound in caves, and these were used in some way by the Ceboynas, perhaps as burial-places, possibly as refuges from the blood-hounds of the Spaniards. The floor of these caves consists of red clay, rich in phosphates and of commercial value, and within recent years it has been removed 96 THE POPULAR SCIENCE MONTHLY. froni most of them and sold. During the excavations many hu- man bones and other relics were found, but they attracted little interest, and most of them were destroyed. I learned, however, during a recent visit to the islands, that a few of the bones had found their way into the hands of thoughtful and intelligent per- sons, and had thus been preserved. Their custodians at once ap- preciated my desire to study them, and generously placed them at my service for this purpose, so that I was able to obtain notes for a pretty complete anthropological description of the Ceboynas. The wife of the governor of the colony, Mrs. Blake, a most enthu- siastic and able naturalist, whose contributions to science are well known, had herself explored one of the caves — an undertak- ing which calls for energy and endurance quite incomprehensible to any one who has never attempted exploration in the tropics. She had found fragments of several skeletons in the cave, and she placed them all in my hands as soon as I expressed a wish to study them. Dr. J. C. Alberry, a Nassau physician, was equally generous with a female skull in perfect preservation, which he had in his office, and both he and Mrs. Blake afterward authorized me to de- posit these relics of a lost and almost unknown race in one of our great anthropological collections. The Nassau Public Library con- tains two male skulls which the trustees kindly permitted me to draw and measure. As the result of my examination of this material, I am now able to state that the Lucayans were large people, about equal in size and stature to the average European, and very muscular and heavy. The bones, especially those of the skulls, are very thick, firm, and heavy, with a surface almost as dense and white as ivory. After examining the skulls, it is easy to credit the statement that the steel swords of the Spaniards were often broken over the hard heads of the Lucayans. The brain was large, and the capacity of the cranium is about equal to that of an average Caucasian skull ; but they had protuberant jaws and the powerful neck- and jaw- muscles of true savages, and the outlines of the skulls have none of the softness and delicacy which characterize those of more civilized and gentle races of men. The eyes were very oblique, sloping downward away from the nose, and the orbits are very large and angular. The cheek-bones are broad and high, and the jaws peculiarly massive and square. The skulls are extremely broad in proportion to their length, and they are among the most brachycephalic, or round-headed, of all known human skulls, the greatest breadth being more than nine tenths of the greatest length. The Ceboynas flattened their heads artificially in infancy, so that the vertical part of the forehead is completely obliterated in all the adult skulls, and the head slopes backward immediately THE LUC AY AN INDIANS. 97 above the eyes. This flattening was practiced to such a degree that the bones of the child's skull were often broken by the press- ure of the bandages, and two out of the four skulls had false joints, which appear to be the result of fracture produced in this way. The type of the race is extremely well marked, and, after one of the skulls had been examined, it was easy to see at a glance that the others belong to the same people, and their characteristics agree closely with the very short description of the Ceboynas which Columbus gives. In his log-book, October 13th, he says: "At dawn many of these men came down to the shore. All are, as already said, youths of good size and very handsome ; their hair not woolly, but loose and coarse like horses' hair. They have broader heads and foreheads than I have ever seen in any race of men, and the eyes very beautiful, not small. None of them are black, but of the complexion of the inhabitants of the Canaries. All, without ex- ception, have very straight limbs, and no bellies, and very well formed." This passage, and a few others in his log-book, contain nearly all that is known of the race, for the rapidity with which discov- ery followed discovery was unparalleled ; and the simple Lucayans attracted little interest or attention after the Spaniards found the large fertile islands of the Antilles and the civilization of Mexico. We know, however, that the statements in the histories to the effect that they were naked, weaponless, and without arts, are in- correct, as they are based upon the impressions which Columbus formed during his first day among them. It is true that the men who welcomed Columbus were naked and without weapons, and that, as they sat in their canoes, with their stiff, black hair cut straight across their low foreheads and hanging down behind in a long scalp-lock, with their naked bodies painted, "some black and some white and some red, and some whatever they find," they must have seemed like thorough sav- ages. He soon found, however, that they had gardens and neat, well-swept houses, and that they knew how to manufacture cotton cloth, and had such simple clothing as suits the climate. Their large canoes, hewed out of the trunks of single trees, were large enough to hold forty or fifty men each, and " wonderfully built according to the locality," and Columbus says they were skillful boatmen, paddling with wonderful speed, and managing them with great dexterity. Fragments of pottery, household utensils of carved wood, and rude pictorial carvings have been found in the islands, and the occasional discovery of beautifully polished stone implements proves, like the piece of gold marked with letters, that they were VOL.

They knew the direction and distance of Cuba and Hayti, and they called the larger island by the name which it still bears. Their language was almost identical with that spoken in these islands, and, while they were upon the extreme edge of the civilization of the Gulf of Mexico, they were not entirely outside its influence, and the discoverers were able to use them as interpreters as far away from their home as Campeachy. This is about the sum total of our knowledge of the Cebay- nas, and does not their share in the discovery entitle them to our remembrance, and bind us to do what we can before November 12, 1892, to preserve them from complete oblivion ? What can we do to perpetuate their memory ? There is one thing which would be a most worthy and becoming testimonial if it were practicable. The injury which they have sustained is past and irreparable, but if three years hence we could celebrate the institution of a wise, humane, and consistent method of dealing with the wards of our nation in place of the one which was ini- tiated when Columbus devoted his first Sunday to a search for a fort, the shades of the Ceboynas might accept the sacrifice. What else is there to be done ? Can we not restore to the map the pretty word " Lucayas " as the name for the islands ? Surely if Columbus has Columbia for his monument, the Lucayans are entitled to the Lucayas ; and while this is only a little thing, it would be a graceful tribute to them. In the little-known interior of the larger islands there are many caves which have never been disturbed. Canoes, stone im- plements, carved utensils, and other articles have been found from time to time in the out-islands, and, while the articles have no great archaeological interest, the part played by their owners in the events which are so soon to be commemorated would give great value to any new discoveries. The delightful climate and the beauty of the landlocked sounds give to the Bahamas the greatest charm as a cruising- ground ; and if some yacht -owner were to devote himself to exploration, with a well-equipped and energetic staff of earnest assistants, he might hope to gather a collection of Ceboyna relics which, placed in one of our museums, would be a permanent monu- ment to their memory. De. Eduard Nattmann, of Munich, has advanced the theory, in a British Asso- ciation paper, that the magnetic curves of the earth, wherever a magnetic survey has been made, show a distinct relation to mountain ranges, faults, eruptions, and tectonic disturbances. He urges that the investigation of this subject be taken up at once all over the world. SPEECH AND SONG. 99 SPEECH AND SONG. By Sib MOEELL MACKENZIE. PART I. — SPEECH. IN dealing with the two great forms of local utterance, it will be most convenient to take them in their historical, or at any rate their logical, order. Whatever " native wood-notes wild " our hypothetical half-human ancestor may have " warbled " by way of love-ditties before he taught himself to speak, there is no doubt that singing as an art is a later development than articulate speech, without which, indeed, song would be like a body without a soul. I will, therefore, treat of speech first ; and it will clear the ground if I begin with a definition. Physiologically, speech is the power of modifying vocal sound by breaking it up into distinct elements, and molding it, if I may say so, into different forms. Speech, in this sense, is the universal faculty of which the various languages by means of which men hold converse with each other are the particular manifestations. Speech is the abstract genus, language the concrete species. I am happy to say it does not fall within the scope of my pres- ent purpose to discuss the origin of language, a mysterious prob- lem, on which the human brain has exercised itself so much and to so little purpose, that some years ago, I believe, the French Academy declined to receive any further communications on the subject. The origin of the voice is a different matter. The vocal function is primarily a means of expression. I see no reason for disagreeing with Darwin, when he says that " the primeval use and means of development of the voice " was as an instrument of sexual attraction. The progenitors of man, both male and female, are supposed to have made every effort to charm each other by vocal melody, or what they considered to be such, and by constant practice with that object the vocal organs became developed. Dar- win seems inclined to believe that, as women have sweeter voices than men, they were the first to acquire musical powers in order to attract the other sex, by which I suppose he means that the feminine voice owes its greater sweetness to more persevering cult- ure for purposes of flirtation. I do not know whether the ladies of the present day will own this soft impeachment, or whether they will be flattered by the suggestion that their remote ances- tresses lived in a perpetual leap-year of courtship. Other emo- tions, however, besides the master passion of love had to be ex- pressed ; joy, anger, fear, and pain had all to find utterance, and the nervous centers excited by these various stimuli threw the whole muscular system into violent contractions, which in the loo THE POPULAR SCIENCE MONTHLY. case of the muscles moving the chest and the vocal cords naturally- produced sound — that is to say, voice. These movements, at first accidental and purposeless, in time became inseparably associated with the emotional state giving rise to them, so as to coincide with it, and thus serve as an index or expression thereof. From this to the voluntary emission of vocal sounds is an easy step, and it is probable enough that the character of those sounds was prima- rily due to the " imitation and modification of different natural sounds, the voices of other animals, and man's own instinctive cries. The mechanism of the voice is extremely simple in its general principles, though highly complex in its details. Fortunately, a knowledge of the latter is not required for the comprehension of the main facts relative to the production of the voice, and I shall not further allude to them here. Vocal sound is produced solely in the larynx, an elementary fact which must be thoroughly grasped, as many absurd notions are current even among people who should know better, such as that the voice may be produced at the back of the nose, in the stomach, and elsewhere. The larynx is a musical instrument of very complex structure, partak- ing both of the reed and the string type, the former, however, dis- tinctly predominating. It is essentially a small chamber with cartilaginous walls, which is divided into an upper and a lower compartment by a sort of sliding floor, or double valve, formed by the two vocal cords. In breathing this valve opens, its two lateral halves gliding wide apart from each other, so as to allow a broad column of air to pass through ; in speaking or singing, on the other hand, the valve is closed, but for a narrow rift along its middle. Through this small chink the air escaping from the lungs is forced out gradually in a thin stream, which is compressed, so to speak, between the edges of the cords, that form the opening technically called the "glottis," through which it passes. The arrangement is typical of the economical workmanship of Nature. The widest possible entrance is prepared for the air which is taken into the lungs, as the freest ventilation of their whole mucous surface is necessary. When the air has been fully utilized for that purpose, it is, if need be, put to a new use on its way out for the production of voice, and in that case it is carefully husbanded and allowed to escape in severely regulated measure, every parti- cle of it being made to render its exact equivalent in force to work the vocal mill-wheel. When the air is driven from the lungs up the windpipe it strikes against the under surface of the floor or double valve formed by the vocal cords, which are firmly stretched to receive the shock, forces them apart to a greater or less extent, and, in rushing out between them, throws them into vibration. * " Descent of Man," second edition, 1882, p. 87. SPEECH AND SONG. 101 The vibration of the vocal cords makes the column of air itself vibrate, and the vibration is communicated to the air in the upper part of the throat, the nose, and mouth, from which finally it issues as sound. The vocal cords are the " reeds " of the vocal instrument, and as, owing to the extraordinary number and intri- cate arrangement of their muscular fibers, they can change their length and shape and thickness in an almost infinite variety of ways, they are equal in effect to many different reeds. If the vocal cords can not move so as to bring their edges almost into contact, or if there is any substance between them which prevents them from coming together, the voice is destroyed ; if there is anything (such as a growth) in or on one of them, its vibration is more or less checked, and hoarseness is the consequence. The primary sound generated in the larynx is modified by the shape, size, and density of the parts through which the vibrating column of air has to pass before it issues from the " barrier of the teeth." These " resonators," include the part of the larynx above the vocal cords, with the little sounding-board, the epiglottis, covering it; the upper part of the throat or pharynx, the nasal passages with cer- tain echoing caves in the bones of the skull which communicate therewith ; and the mouth, with the soft palate and uvula, tongue, cheeks, teeth, and lips. It is to these resonators, as well as to the size and shape of the larynx itself — and those parts, like the feat- ures of the face, are never exactly similar in any two individ- uals— that the distinctive quality, or timbre, of the voice is due. Timbre is the physiognomy of the voice by which the speaker can be recognized even when unseen. Just as the face may be lit up with joy, darkened with sorrow, or distorted with passion, so may the voice be altered by strong mental emotion. This is due to the influence of the mind on the nervous system, which con- trols every part of the body : if it be stimulated, increased action will be excited ; if disordered by shock, feeble irregular move- ments will be produced, the limbs will shake, and the voice trem- ble. From the effect of peculiarities of physical conformation on the voice it will be readily understood that timbre may be, in some degree, a national or racial peculiarity. There are also certain physical types which correspond to particular timbres of the voice. I have noticed this particularly in persons of like complexion even when different in race. Thus, a certain sharp metallic clearness of articulation is often found in individuals of ruddy complexion, light yellow hair, and hard blue eyes, while rich, mellow tones, with a tendency to portamento in ordinary speech, are often asso- ciated with black hair and florid face. A remarkable point is that the same voice may be altogether different in timbre in singing from what it is in speaking. The difference is probably due to the fact that in singing the resonators are, instinctively, or as the loz THE POPULAR SCIENCE MONTHLY. result of training, managed in a more artistically effective manner than in ordinary speech. Speech differs from song as walking does from dancing ; speech may be called the prose, song the poetry of vocal sound. Mr. Her- bert Spencer has denned song as " emotional speech," but this term might with greater justice be used to designate the hystero- epileptic oratory which threatens to become acclimatized in this sober island, or even to the exchange of amenities between two angry cabmen. It would be more accurate to call song " musical speech," using the word " musical " in its strict sense as signifying sound with definite variations of tone and regularity of time. But, just as there may be " songs without words," so there may be speech without voice, as in whispering. Sound, as we have already seen, is produced in the larynx, but articulation, or the transforma- tion of meaningless sound into speech, is performed in the mouth ; in speaking, therefore, the two parts work together, the larynx sending out a stream of sound, and the mouth, by means of the tongue, cheeks, palate, teeth, and lips, breaking it up into vari- ously formed jets of words. In other words, the larynx supplies the raw material of sound which the mouth manufactures into speech. Time, which is an essential element of song, is altogether disregarded in speech, while the intervals of tone are so irregular as to defy notation, and are filled up with a number of interme- diate sounds instead of being sharply defined. The voice glides about at its own sweet will in speaking, obeying no rule whatever, while in song it springs or drops from one tone to the next over strictly measured gaps. In singing, short syllables are lengthened out and cease in fact to be short, and (except in certain kinds of dramatic singing and in recitative) the accent naturally falls on the vowels and not on the consonants. In speaking, only the lower third of the voice is employed as a rule, while in singing the greatest effect is generally produced, except in the case of contral- tos and basses, by the use of the upper and middle notes. In speech the range of tone, even in the most excitable persons, hardly ever exceeds half an octave; in singing the average compass is two octaves. Singing tends to preserve purity of language, the rules which govern the utterance of every note also affecting the artic- ulate element combined with it, and keeping the words cast in fixed forms — a stereotype of sound, if I may venture the metaphor. Speech, on the other hand, like handwriting, is always changing. As Max Miiller says : " A struggle for life is constantly going on among the words and grammatical forms in each language. The better, the shorter, the easier forms are constantly gaining the upper hand, and they owe their success to their own inherent virtue." * Thus speech not only tends to split language into dia- * " Nature," January 6, 1870. SPEECH AND SONG. 103 lects, but each dialect is being continually, though imperceptibly, modified not only in construction but in pronunciation. The pronunciation of an Englishman of Chaucer's day would be unin- telligible to us, while that of one of Shakespeare's contempora- ries would be as strange to our ears as the accent of an Aberdeen fishwife is to the average cockney. If the speaking voice has a distinctly sing-song character — that is to say, if it proceeds by mu- sical intervals — the result is as grotesque as it would be to talk in blank verse, or, as Sir Toby Belch says, " to go to church in a gal- liard and come home in a coranto." On the other hand, the speak- ing voice becomes most sympathetic in its quality when it ap- proaches the singing voice, the musical character, however, being concealed by the variety of its inflections. It is important that in speaking a musical note should never be recognized ; the effect is as unpleasant to our ears as an accidental hexameter in a sentence of prose was to the ancients. Wide as the difference is between speech and song, the great gulf fixed between them is partly filled up by intermediate modes of using the voice which partake of the nature of both. Thus there is the measured utterance of declamation, which may be so rhythmical in time and varied in tone as to be almost song. On the other hand, the recilativo of the opera approaches speech. Va- rious intermediate forms between speech and song may be heard in the ordinary speech of certain races, notably in Italians, Welsh- men, and the inhabitants of certain parts of Scotland and Eng- land. The Puritans, as is well known, uttered their formal and affected diction in a peculiar nasal tone ; and the term " cant," though properly belonging to their sing-song delivery, came to be applied to the sentiments expressed by it. Many of the ancient orators, to judge from the description left us by Cicero and Quin- tilian, would seem to have sung their speeches, the style of dec- lamation being, in fact, expressly termed cantus obscurior. As they generally spoke in the open air, and to vast audiences, this artificial mode of delivery may have been necessary in order to make the voice reach farther than if they had spoken in a more natural way. C. Gracchus used to have a musician behind him while he spoke, to give him the note from time to time with a mu- sical instrument called a tonarion. A similar plan might, with much advantage to the " general ear," be adopted by certain mod- ern orators, the crescendo of whose enthusiasm expresses itself in increasing intensity of shrillness. Those who have not given much attention to the subject are apt to think of speaking, as Dogberry did of reading and writing, that it " comes by nature " — that it is, in fact, an instinctive act, which no more needs cultivation for its right performance than eating or sleeping. This is a great mistake. Speaking, even of 104 THE POPULAR SCIENCE MONTHLY. that slipshod kind which is mostly used in ordinary conversation, is an art, and as such has to be learned, often with much labor. The complicated muscular actions, the nice nervous adjustments, the combination of these into one harmonious effort directed to a particular end, and, finally, the mastery of all these movements till they can be produced automatically without a direct and con- tinuous exercise of will-power, form a complex process which takes years to learn, and which by many is even then very imper- fectly acquired. Good speaking is a higher development of the art, which bears the same relation to speech as ordinarily heard that the horsemanship of an Archer or a Cannon bears to the per- formance of a costermonger's boy on the paternal donkey. A man who speaks well not only makes himself intelligible to his hearers without difficulty to them, but with a minimum of effort on his own part. If the voice is properly used, the throat hardly ever suffers, but wrong production is a fertile source of discomfort and even disease in that region. It should be clearly understood that public speaking, in addition to its intellectual aspects, is a physical performance which requires " wind " and " muscle " and the perfect management of one's bodily resources, like any other athletic feat. To attempt to speak in public with- out previous training is like trying to climb the Matterhorn without preparation, and is just as certain to end in failure if not disaster. It is hardly an exaggeration to say that the training of the voice should begin almost in the cradle. I do not, of course, mean that a baby should be taught to squall according to rule, or that the prattle of children should be made a laborious task. But I wish to insist on the importance of surrounding the child, as soon as it begins to lisp, with persons who speak well. "All lan- guages," as old Roger Ascham says, " both learned and mother tongues, are begotten and gotten solely by imitation. For as ye use to hear so ye learn to speak ; if you hear no other ye speak not yourself ; and whom ye only hear of them ye only learn." Quintilian says : " Before all . . . let the nurses speak properly. The boy will hear them first, and will try to shape his words by imitating them." This applies chiefly to pronunciation and the correct use of words ; but much might also be done for the right management of the voice if every child could grow up among people who speak well. I should be disposed to make it an essen- tial point in the selection of a nurse or governess that she should have a good voice as well as a refined accent. In antiquity the training of an orator was almost as elaborate an affair as the training of a race-horse is with us. Not only the voice, but the whole man, physical, intellectual, and moral, was carefully prepared, with conscientious minuteness of detail, for SPEECH AND SONG. 105 the great business of life, the making of speeches. In this system of education the development of the voice naturally held a large place, and the phonascus, or voice-driller, was an indispensable accessory, not only of every school of oratory, but of many formed orators. Of the methods of the phonascus we know little, but we find hints in some of the classical writers that, like certain of his professional brethren in more recent days, he was not disinclined to magnify his office. Seneca, in one of his letters, warns his friend against living, vocally speaking, in subjection to his pho- nascus, and implies that he might as well keep another artist to superintend his walking. In our own day the phonascus still sur- vives in public life, though perhaps more as a luxury than an acknowledged necessity. A celebrated novelist, dramatic author, and orator, who passed over to the great majority many years ago, used always to put himself under the guidance of a vocal mentor before delivering a speech. Every tone, every pose, and every gesture was carefully prepared and industriously practiced, under the direction of Mr. Frederick Webster, brother of the cele- brated comedian, Benjamin Webster. That the elaborate train- ing of the ancients was eminently successful is shown by the pow- ers of endurance which it is clear they must have possessed. They habitually spoke for five or six hours, and even longer, and, in order to appreciate their staying power, it must be remembered that they spoke in the open air, amid all the tumult of the forum, which was capable of holding eighty thousand people, and with an amount and vigor of action of which the gesticulations of an Italian preacher are but a pale reflex. Long-windedness was at one time cultivated as a fine art by Roman orators, when they had to plead before a judge whom they supposed to be in favor of the other side. These prototypes of our modern obstructionists were aptly termed moratores, or delayers, because they postponed as far as possible the passing of the sentence. The abuse finally reached such a height that a law had to be passed limiting the length of pleadings in public cases to the running out of one clepsydra. It is impossible to say exactly what period of time this was equivalent to, as the water-clocks of the Romans were of different sizes, and the rapidity of flow must have varied under different circumstances ; from twenty minutes to half an hour may, however, be taken as roughly representing the average length of a speech under this strict system of "closure." On the whole, I think we use the voice in public even more than the ancients, and there is, there- fore, all the more reason for its being properly trained. Good speaking is nowadays important, not only from the artistic but from the business point of view ; and, even for " practical men," it can not be a waste of time to acquire so valuable a faculty. These arguments may perhaps seem superfluous, as the proposition they io6 THE POPULAR SCIENCE MONTHLY. are intended to support is self-evident. I lay stress on them, how- ever, because I am convinced that the necessity of training the speaking voice is very imperfectly appreciated by most people. It is not within my province to discuss the technical details of voice-training. I will only say that every system of vocal in- struction should aim at strengthening the power of the voice, increasing its compass, and purifying its tone, and, above all, at giving the speaker perfect control over it, even in the very whirl- wind of oratorical passion. It would be well if every school in the land had a master of elocution attached to it, and if the art of delivery were taught to every boy as part of the regular course of education. In the excellent system of education which Rabelais sketched out, the development of the voice is expressly mentioned as part of Gargantua's athletic training. In the middle of a de- tailed description of his swimming and climbing exercises and practice in the use of weapons of all kinds, we are told that " pour s'exercer le thorax et poulmons crioit comme tous les diables. Je l'ouy une fois appellant Eudemon depuis la porte Sainct Victor jusques a Montmartre. Stentor n'eut onques telle voix a la bataille de Troye." * There is a hint for schoolmasters of the present day. The " young barbarians " under their charge might by degrees be made to look on strength and beauty of voice, and skill in using it, as an athletic distinction; this would at once ennoble the sub- ject in their eyes, and make elocution a matter of keen competition. As part of the general vocal training which I think desirable, I should be disposed to urge that all children and young people should learn to sing as far as their natural capacity will allow. Even those with little or no musical endowment will thus learn to use their voices better in speaking. I may say here, though it is rather anticipating, that, if I think it desirable for speakers to learn to sing, I think it still more necessary that singers should learn to speak. Too many of those who soar aloft on the wings of song despise the musa pedestris of speech, and take no trouble to acquire what they look upon as an inferior and possibly super- fluous accomplishment — with what result is known to cultivated listeners whose ears have been tortured by the uncouth distortions and mutilations to which singers often subject the words they have to utter. Of the management of the voice I can not say much here. The chief thing is that the speaker should make himself dis- tinctly heard by the whole of the audience, and to this end art serves better than loudness. A weak voice, properly managed, will carry farther than 9 powerful organ worked by sheer brute * For exercise, his throat and lungs cried out like all the devils. I once heard him calling Eudemon from the Porte Saint Victor to Montmartre. Stentor in the Trojan War had no such voice. SPEECH AND SON-G. 107 force. Mr. B right's use of his voice always gave one the impres- sion of a large reserve of power. There seemed to be no effort in his delivery, even when speaking to a mighty concourse of people, and yet his voice was "To the last verge of the vast audience sent, And played with each wild passion as it went." One element of success in this matter is no doubt the art of com- pelling an audience to listen. As Montaigne, in his quaint old French, says : " La parole est moitie" a celuy qui parle, nioitie* a celuy qui l'escoute ; celuy cy se doibt preparer a la recevoir, selon le bransle qu'elle prend: comme entre ceulx qui jouent a la paulme, celuy qui soubstient se desmarche et s'appreste, selon qu'il veoid remuer celuy qui luy jecte le coup et selon la forme du coup." * Every speaker should know the exact limits of his own vocal pow- ers, and he must be careful never to go beyond them, for the sake of his hearers no less than his own. He must learn to judge in- stinctively of distance, so as to throw his voice to the farthest part of his audience. A speaker, and, I may say, a singer also, should not hear his own voice too loudly. Artistes and orators are often very much disappointed, and think their voice is not traveling well when they themselves do not hear it very distinctly. The fact is that when the speaker does not hear his voice this proves that it reaches to a distant part of the room, and that there is very little rebound. Here I may remark that we never hear our voices as other people hear them. Our own voices are conveyed to the auditory nerve, not only through the outside air, but more directly from the inside, through the Eustachian tube, as well as through the muscles and bones of the mouth and head ; the singer not only hears his own voice from a different quarter, as we may say, but he hears besides the contraction of his own muscles. The fact is well illustrated by the phonograph : a listener can recognize other people's voices, but if he speaks into the phonograph, and after- ward reproduces his own voice, it does not sound at all like itself to him, because he does not hear it in the manner he is accustomed to, and because he hears it stripped of the various accompanying sounds which are usually associated with it to his ear. The acoustic peculiarities of the place in which he has to speak must, if possible, be carefully studied beforehand by the orator. Public buildings, however, vary so greatly in their size and con- struction that it is impossible to lay down any general rules for the guidance of speakers in this matter. Each hall, church, court, and theatre has its own acoustic character, which can be learned * Speech belongs half to the speaker and half to the hearer ; the latter should prepare himself to receive it, according to the impetus it obtains. As with tennis-players, the one to whom the ball is served poses and makes ready according to the motions of the server and the form of the service. 10S THE POPULAR SCIENCE MONTHLY. only by experience ; the voice must be, as it were, tuned to it. It is well if this experience can be gained by the orator before he faces his audience ; but he must remember that trying his voice in an empty room is an altogether different thing from actually using it in the same place packed with a solid mass of wheezing, cough- ing, and perspiring humanity. Handel is said to have comforted himself, when one of his oratorios had been performed to empty benches, by the reflection that " it made ze moosic shound all ze better," but this consolation is denied to the orator. There are some buildings which are so utterly bad from the acoustic point of view that even experienced speakers are little better off than novices. The House of Lords has, or used to have, an unenviable reputation in this respect. A story is told of the late Lord Lyttel- ton that, after exhausting his voice in vain efforts to make his brother peers hear a motion which he wished to propose, he in despair wrote it down and asked the clerk at the table to read it out. That functionary, however, was quite unable to decipher the writing, and Lord Lyttelton complained that he was cut off from communication with his fellows. Science has not always been successful in coping with the acoustic difficulty. In 1848 it was so difficult for speakers to make themselves heard in the French Chamber, that a committee, consisting of the leading scientific luminaries of the day — such as Arago, Babinet, Dumas (the chem- ist, not the author of " The Three Musketeers "), Becquerel, Chev- reul (the centenarian who died the other day), Pouillet, Regnault, and Duhamel — was appointed to study the case and suggest a remedy. After numerous experiments they hit on a contrivance, designed on the most scientific principles, which was to make the orator's voice ring like a clarion to the farthest benches. The last state of the speaker, however, was worse than the first ; he felt as if his voice was stifled under a huge night-cap, and the highly scientific sound-reflector had to be discarded as a failure. Indeed, modern public buildings are so often defective in this respect that I am not surprised to find M. Ch. Gamier, who designed the Grand Opera in Paris, exclaiming dolefully, " The science of theatrical acoustics is still in its infancy, and the result in any given case is uncertain." So impressed is he with the shortcomings of modern architecture as regards the conveyance of sound, that he frankly confesses that, in the construction of the Opera-House, he " had no guide, adopted no principle, based his design on no theory " ; he simply left the acoustic properties of the building to chance. The result has not been altogether satisfactory, though it has been no worse than in many other buildings where the architect did his best to make the acoustic conditions perfect. One of the most remarkable buildings from the acoustic point of view that I have ever seen is the beehive-shaped Temple in Salt Lake City. It SPEECH AND SONG. 109 holds from twelve to fourteen thousand people, and one can liter- ally hear a pin fall. When I was in the Temple, with some other travelers, in 1882, the functionary corresponding to the verger of ordinary churches stood at the farthest end and dropped a pin into his hat. The sound of its fall was most distinctly audible to all present. The scratching of the pin against the side of the hat was also plainly heard across the whole breadth of the building. The Temple was designed by Brigham Young, who professed to have been directly inspired by the Almighty in the matter, as he knew nothing of acoustics. The resonance of the building is so loud that branches of trees have to be suspended from the ceiling in several places in order to diminish it. It is likely enough that Brigham Young's inspiration had a not very recondite and purely terrestrial source, for his Beehive is only a slight modification of the whispering-gallery in St. Paul's. The bad acoustic properties of buildings may be remedied by what doctors call " palliative treatment." Charles Dickens's experience as a public reader made him a man of ready resource in meeting such difficulties. On one occasion, when he was going to lecture at Leeds, Mr. Edmund Yates, who had spoken in the same hall the evening before, sent him word that the acoustic conditions of the place were very bad. Dickens at once telegraphed instructions that curtains should be hung round the walls at the back of the gallery ; by this means he was able to make himself more easily heard. The speaker should take the greatest care of his voice, which is the instrument both of his usefulness and of his fame, but of course it is not always easy for him to do so. Still, he should, if possible, make it a rule not to speak when his voice is hoarse or fatigued, and, when he has a great oratorical effort to make, he should reserve himself for it. Tobacco, alcohol, and fiery condi- ments of all kinds are best avoided by those who have to speak much, or at least they should be used in strict moderation. I feel bound to warn speakers addicted to the " herb nicotian " against cigarettes. Like tippling, the effect of cigarette-smoking is cumu- lative, and the slight but constant absorption of tobacco juice and smoke makes the practice far more noxious in the long run than any other form of smoking. Our forefathers, who used regularly to end their evenings under the table, seemed to have suffered little of the well-known effects of alcohol on the nerves, while the modern tippler, who is never intoxicated, is a being whose whole nervous system may be said to be in a state of chronic inflamma- tion. In like manner cigarette-smokers (those at least who inhale the smoke, and do not merely puff it " from the lips outward," as Carlyle would say) are often in a state of chronic narcotic poison- ing. The old jest about the slowness of the poison may seem ap- plicable here, but, though the process may be slow, there can be no THE POPULAR SCIENCE MONTHLY. little doubt that it is sure. Even if it does not kill the body, it too often kills or greatly impairs the victim's working efficiency and usefulness in life. The local effects of cigarettes in the mouth must also be taken into account by those whose work lies in the direction of public speech. The white spots on the tongue and inside of the cheeks, known as " smoker's patches," are believed by some doctors with special experience to be more common in devotees of the cigarette than in other smokers ; this unhealthy condition of the mouth may not only make speaking troublesome, or even painful, but it is now proved to be a predisposing cause of cancer. All fiery or pungent foods, condiments, or drinks tend to cause congestion of the throat, and if this condition becomes chronic it may lead to impairment, if not complete loss, of voice. The supposed miraculous virtues of the mysterious possets and draughts on which some orators pin their faith exist mainly in the imagination of those who use them ; at best they do nothing more than lubricate the joints of the vocal machine so as to make it work more smoothly. This is just as well done by means of a glass of plain water. In France water sweetened with sugar is the grand vocal elixir of political orators. As Madame de Girar- din said, somewhat unkindly : " Many things can be dispensed with in the Tribune. Talent, wit, conviction, ideas, even memory, can be dispensed with, but not eau sucree." Stimulants may give a sort of " Dutch courage " to the orator, and may carry him suc- cessfully through a vocal effort in which indisposition or nervous- ness might otherwise have caused him to fail, but the immediate good which they do is dearly purchased by the thickening and roughening of the mucous surface of the throat to which they ultimately give rise. Before leaving the subject of the speaking voice, a word or two may be said on what is more a matter of curious speculation than of practical interest. Is the human voice growing in power and beauty, or is it tending to decay ? Certain physiologists assure us that the retina has acquired the power of distinguishing colors by degrees, and that the process will probably continue, so that our descendants will by and by evolve the power of seeing colors now quite unknown to us. On the other hand, it is undeniable that civilization, so far from increasing the keenness of our sight, threatens to make spectacles universally necessary. There can be no doubt that the voice has developed greatly since our " half -hu- man ancestors " wooed each other in the primeval forests, and it is conceivable that it may in time to come acquire the power of producing musical effects at present undreamed of. It is also probable enough that as the voice gains in sweetness it may lose in power, the latter quality being more required in barbarous than in highly civilized conditions. On the other hand, we are taller SPEECH AND SONG. m and of larger chest-girth than onr predecessors even of a not very- remote date ; it is reasonable, therefore, to suppose that the aver- age lungs and larynx are bigger nowadays, and the air-blast from the lungs stronger. This would appear to justify us in believing that the voice is stronger than it was even two or three centuries ago. There are, however, no facts that I know of to prove it. Of the ethnology of the voice little or nothing is certainly known. Almost the only facts I know of coming under this head are — (1) the superior sonorousness of the Italian voice, and (2) the want of resonance in the voices of some Australian aborigines, which is supposed to be due to the extreme smallness of the hollow spaces in the skull which serve as resonance chambers. Yet there is an infinite diversity in the voices of different nations, arising from difference of physical conformation, habit of speech, climate, etc. It is to our climate that Milton attributed the fact, which strikes all foreigners, that English people speak with the mouth half shut. " For we Englishmen," he says, " being far northerly, do not open our mouths in the cold air wide enough to grace a southern tongue, but are observed by all other nations to speak exceeding close and inward ; so that to smatter Latin with an English mouth is as ill a hearing as law French." Then look at our American cousins, in whom it is not the mouth but the nose that is the " peccant part " — is it climate or variation of structure that has wrought the change in their original English speech ; or is it simply a twang inherited from their Puritan ancestors, who took their " cant " with them to the New World ? Americans, including even so refined a scholar as Mr. Lowell, boast that they alone keep the true tradition of English speech ; but I can not believe that our forefathers, " in the spacious times of great Elizabeth," spoke in the accents of Hosea Biglow. The difficulty, or rather impossi- bility, of studying the variations of the voice under culture has been due to the want of any means of permanently recording its tones. Now, however, that the phonograph has emerged from the condition of a scientific toy, comparative phonology may, per- haps, take its place among the sciences. Besides this and other results, Mr. Edison's wonderful instrument will preserve the fame of orators, actors, and singers — hitherto the most evanescent kind of glory, as it had to be taken altogether on trust — in a form as concrete as a picture or a poem. The little revolving cylinders will reproduce " the sound of a voice that is still," and will enable us to have " the little voice set lisping once again " years after our darling has been laid in an untimely grave. There seems to be something almost uncanny in the power of thus permanently en- shrining the most fleeting part of man, and reawakening at will the living accents of one who, being dead, yet speaketh to the bodily ear. — Contemporary Review. 112 THE POPULAR SCIENCE MONTHLY. SKETCH OF PROF. JOHN LE CONTE. By Peof. W. LE CONTE STEVENS. THE subject of the present sketch is the Professor of Physics in the University of California, where he has for many years been associated with his brother, the distinguished geologist and writer on evolution. He was the second son of Louis Le Conte, and was born on the 4th of December, 1818, at the family home- stead in Liberty County, Georgia. The father was a man of much independence of character, firm and decided, yet kind and gentle, exceedingly fond of investigation, original in thought, but singularly indifferent to popular recognition. He published noth- ing himself, and would never have become known away from his own home, had not others been appreciative enough of his real merit to give some of his results to the world by presenting them before the New York Lyceum of Natural History. By personal influence and example, Louis Le Conte inculcated in his sons the love of science, and of truth for its own sake. The virtue of verification was one which he sought to cultivate in them as of cardinal importance. An illustration of the success of his teaching in this direction, and of the early growth of the philosophical habit of mind in his son John, was afforded on one occasion when the father and a number of neighbors, while pa- trolling at night to check some illicit transactions between the negro slaves and the shopkeepers of the nearest village, were fired upon with blank cartridges, and thrown from their startled horses. Relating the story of his mishap after he had reached home, the father said, " I lost my left stirrup ; at the turn in the road I lost the other stirrup, and at the next turn I was thrown." John, who listened to the narrative with great interest, was perplexed to know how the stirrups could have been lost. His night's rest did not remove the trouble, and, leaving his bed before sunrise, he went and examined the saddle. He reported upon the result of his investigation at the breakfast-table. " Pa, did you not say last night that, when the horse ran away with you, you lost your stirrups ? " " Yes, my son, I did say so/' " Well, I have found that the stirrups are safe and sound." The laugh was turned against the son, and the father often told the story afterward as a joke upon him. It was, however, no joke ; it was a prediction of the career of the future investigator in physics. The childhood and most of the boyhood of John Le Conte were spent at the plantation home in Georgia, where hunting, fishing, boating, and all kinds of athletic sports contributed largely to the training of his observing faculties. His uncle, Major Le Conte, SKETCH OF PROF. JOHN LE CONTE. n3 an accomplished zoologist, often gave np his New York home in winter for the purpose of spending the colder months on the Southern plantation. The scientific proclivities of both father and uncle insensibly made all the children students of natural history and collectors of specimens. Thus they gradually imbibed knowledge on such subjects, and acquired powers of discrimina- tion that are ordinarily attained only by years of study in maturer life. Their mother died in 1826, leaving the father in charge of six children. Deprived of maternal care at so early a period of life, all of them, and especially the boys, were thrown largely upon their own resources at a tender age. In those days and in that country neighborhood, forty miles from the nearest city, Savannah, it was necessary to do without the school accommodations that are now abundant in every vil- lage of our land. An isolated wooden-framed house, with no plastering, a single door for its single room, abundant ventilation through the crevices of the floor and walls, fully supplemented by the draught through an ample clay chimney — such was the school-house in which the children were gathered daily from plantations varying in distance from one to half a dozen miles or more. The teacher was rarely ever of the best. One there was who took charge of this road-side seminary for two years, became the intimate friend of Mr. Le Conte, and exerted over his boys an influence that became life-long. Alexander H. Stephens, the fu- ture statesman and historian, was then a young graduate who sought in teaching the pecuniary support that was necessary while he was preparing for admission to the bar. His fine classi- cal taste and clear, logical mind produced a lasting impression upon John Le Conte, who received thus his training for college, and entered Franklin College, now the University at Athens, Ga., with distinguished success in January, 1835. As a student, young Le Conte soon became noted for his clear- ness of conception and his scrupulous accuracy in work. The curriculum of study was the same for all, irrespective of native bias or prospective aim in life. He was fully appreciative of all the classical culture that was there afforded, but his tastes natu- rally led him into spending on mathematics and its- applications a larger share of attention than Latin and Greek could attract. " Give him the cosine of A and he will prove anything," was the criticism expressed by an admiring fellow-student, and concurred in by the rest. The formal teaching of physics and chemistry involved mere text-book recitation, and attendance upon illus- trated lectures of the most elementary character, which were delivered with oracular authority. It was more than whispered among the students that on these topics John Le Conte knew as much as or more than the professor himself. VOL. XSXYI. 8 n4 THE POPULAR SCIENCE MONTHLY. During his senior year at college Mr. Le Conte was bereft of his devoted father, who died after a very brief illness. This ca- lamity hastened his selection of a profession. In August, 1838, he was graduated with high honor. Immediately afterward he began the study of medicine, and in the spring of 1839 he entered the College of Physicians and Surgeons in New York, where, in March, 1811, he received the degree of Doctor of Medicine. A few months before his graduation in medicine another domestic calam- ity befell him in the death of his eldest brother, William, to whom had been committed the charge of the family estates in Georgia. This event hastened Dr. Le Conte's return home in the spring of 1841, to take charge of the estate as the eldest surviving son, and frustrated the execution of a cherished plan for supplementing his medical education by a year's residence in Paris. During the summer of 1811 Dr. Le Conte returned to New York, and was married in July to Miss Josephine Graham, of that city, an accomplished young lady of Scottish and English extraction. The deep love and earnest devotion, and the consequent domestic happiness which crowned this union, contributed more than all else afterward to fortify and sustain him in the battle of life. Mrs. Le Conte was a woman of wonderful personal magnetism, queenly in bearing, and of extraordinary beauty. Her brilliancy and wit, her quick insight and ready tact, added to her majestic presence, made her the center of attraction in every social gathering. In after-years, especially at the annual meetings of the American As- sociation for the Advancement of Science, such men as Bache, Peirce, Henry, and Agassiz vied with each other in doing her homage. Her fame in social circles equaled that of her husband among men of science ; and no important step in his life has been taken without acknowledgment of the help derived from the so- cial influence of a wife of whom he was justly proud. In the autumn of 1842 Dr. Le Conte established himself as a practitioner of medicine in Savannah, Georgia. His four years of residence in that city formed no exception to the usual experience of a young doctor : a very small practice and an increasing fam- ily. It afforded, however, an excellent opportunity for study and research, and it was during this period that he made his most im- portant contributions to medical literature. These at once estab- lished his reputation in the profession as an acute observer, cau- tious, exact, and industrious. The first of them, entitled " A Case of Carcinoma of the Stomach," published in the " New York Med- ical Gazette " in 1842, was the initial outcome of a series of obser- vations on cancer that has been continued from time to time, even after Dr. Le Conte's abandonment of the practice of medicine. At this period he probably paid more attention to physiology than to any other of the departments included in medical science, and his SKETCH OF PROF. JOHN LE CONTE. "5 fondness for research, interfered to some extent with the efforts that might have been made to secure paying patients. In August, 1840, Dr. Le Conte accepted the chair of Natural Phi- losophy and Chemistry in Franklin College, his alma mater, from which he had gone forth eight years before as the best scientific student in his class. This decided his withdrawal from the field of practical work in medicine. Henceforth he devoted himself to the study of physical science, but without failing to keep pace still with the progress of physiology. He retained his professor- ship at Athens for nine years, resigning it in the autumn of 1855 to become lecturer on chemistry in the College of Physicians and Surgeons, his medical alma mater. In the spring of 1856, at the conclusion of his course of lectures in New York, he accepted a call to the South Carolina College at Columbia, where he had been unanimously elected to fill the chair, then first created, of Natural and Mechanical Philosophy. This position he held until the col- lege was disbanded soon after the opening of the civil war. He was then put in charge of the Niter and Mining Bureau of South Carolina. In 1866 the University of South Carolina was organ- ized, and Dr. Le Conte was elected to the same chair that he had held in the college of which this was the new development. This position he retained until 1869, when he gave up his residence in Columbia to become an adopted citizen of California. Here his home has continued up to the present time. The period of thirteen years embracing Dr. Le Conte's connec- tion with the South Carolina College and University, although clouded by the saddening events incident to the civil war, con- stituted the pleasantest and most satisfactory period of his life. The institution was governed by a board of trustees composed of gentlemen of refinement and culture, who entertained a genuine sympathy for the labors of the student who strives to plant him- self at the most advanced outposts of science and literature. The community amid which the college had been developed was strongly influenced by the atmosphere of scholarship which it produced. There was a quiet spirit of encouragement to learn- ing, which, by its freedom from pretension, furnished the most grateful incentive to study. It was during these years that Dr. Le Conte established a European reputation through his writings, which were published chiefly in the " American Journal of Sci- ence " and the " London Philosophical Magazine/' It was in 1857 that he made the remarkable discovery of the sensitiveness of flame to musical vibrations — a discovery which served as the starting-point for Barrett, Tyndall, and Koenig in the exquisite applications that have since been worked out by the use of flame for the detection of sounds too delicate for the ear to perceive, and for the optical analysis of compound tones. Unfortunately, n6 THE POPULAR SCIENCE MONTHLY. Dr. Le Conte did not possess the wealth, of instrumental appli- ances needed for the development of his unique discovery, but his priority was gracefully proclaimed by Tyndall in the now classic book on sound, made up of lectures delivered at the Royal Insti- tution. Among other papers that attracted marked attention in Europe was one " On the Adequacy of Laplace's Explanation to account for the Discrepancy between the Computed and the Ob- served Velocity of Sound in Air and Gases," written in 18G1 and published in 1864. Laplace's modification of Newton's formula had been questioned by eminent English mathematicians and physicists. Dr. Le Conte showed that the obscurity into which the subject had been thrown was due to misconception of the physical theory of Laplace, and to the difficulties and obscurities which invest the mathematical theory of partial differential equa- tions in their application to physical questions. This paper evoked replies from Profs. Challis, Earnshaw, and Potter, in England ; but the American physicist's position is generally accepted to- day. The paper is a model of exact physical reasoning. In addi- tion to the discussion of Laplace's views, it contains an original investigation of the bearing of the phenomena attending the propagation of sound in air on the question whether the gases constituting our atmosphere are in a state of mixture or of com- bination. Just before the close of the war the home of Dr. Le Conte was included in the belt of desolation that was left by General Sher- man's march through South Carolina. Among the losses by fire was the manuscript of a volume on general physics, the product of Dr. Le Conte's many years of experience as a teacher and stu- dent of this subject. The tribulations of the reconstruction period in South Carolina during the years following the war made sci- entific investigation impossible. The political turmoil, and the inauguration of the rule of ignorance and vice in place of intel- ligence, left no refuge but expatriation for those whose occupa- tions depended upon the embellishments of civilization. To this source of disquietude was added the burden of domestic affliction in the loss of an only daughter in the bloom of early womanhood. At this critical time came a call to the Pacific coast, to assume the chair of Physics and Industrial Mechanics in the University of California, which was then in the incipiency of its organiza- tion. The offer was accepted, and Dr. Le Conte arrived in San Francisco in April, 1869. Being immediately appointed acting president, he drew up the first prospectus of the university, in which was set forth a synopsis of the proposed courses of instruc- tion. In September of the same year exercises were begun in temporary buildings at Oakland, where during the following sum- mer he conferred the baccalaureate degree on three young men, SKETCH OF PROF. JOHN LE CONTE. 117 and then retired from executive duties in order to build up more thoroughly his own department of work. On the resignation of President Gilman in 1875, Dr. Le Conte was induced again to assume the presidency, which he retained until June, 1881, but still performing the duties of his professorship. Since that date he has confined himself to his chair of Physics. Through nearly the whole of life the two brothers, John and Joseph Le Conte, have been closely associated, each attaining eminence, the elder as a physicist, the younger as a geologist. The elder preceded the younger by six years at Franklin College, in Georgia. They went almost together to the South Carolina College, and likewise to the University of California. This fact has often led to their names becoming confounded by strangers. Dr. Le Conte is a member of the National Academy of Sciences, the American Association for the Advancement of Science, the American Philosophical Society and Academy of Natural Sci- ences in Philadelphia, the New York Academy of Sciences, and the California Academy of Sciences. To this list might be added various other bodies which have bestowed upon him honorary membership. A list of some of the more important of Dr. Le Conte's pub- lished writings is appended. The entire list is too long for inser- tion, amounting to about a hundred papers. Of the first dozen, which show the direction of his tastes as a physician, perhaps the most interesting is No. 9, in which by origi- nal experiments he proved that the alligator is able to execute de- liberate and determinate movements after decapitation and even after destruction of the spinal cord. In No. 10 he shows that the mortality from cancer has in- creased in modern times ; that it augments regularly with in- creasing age, and that it is greater in France than in England. The same subject is pursued still further in No. 28 and No. 49, in which he shows important errors in the usual methods of in- terpreting vital statistics, and that the average mortality from cancer is fully three times as great among females as among males. In No. 16 he gives the first rational explanation of a whole class of ice phenomena as manifested both in the ground and in plants. In No. 17 the investigation is continued, and from nu- merous experiments it is shown that many plants may be com- pletely frozen without injury. No. 19 is a criticism of Moseley's theory of the descent of glaciers, in which it is demonstrated that the descent can not be produced by expansions and contractions of the ice due to changes of temperature. In No. 20 it is shown that Maury's theory of the winds is un- u8 THE POPULAR SCIENCE MONTHLY. tenable. This conclusion is now universally accepted, great as was the value of Maury's work in the pioneer days of meteorology. In No. 23 it is shown that solar light has no sensible influence on combustion. This paper, as well as Nos. 16 and 17, was exten- sively reproduced in Europe. The same remark applies to Nos. 24 and 26, which have been already discussed. In Nos. 25 and 39 an account is given of investigations regard- ing the depth, transparency, and color-tints displayed in some re- markable bodies of water. No. 35 contains the description and discussion of some unique experiments on the propagation of vibrations through water, the source of disturbance being explosions of great violence. The re- sults were wholly new, and attracted much attention in Europe. In Nos. 37 and 41 the principles of capillarity are very thor- oughly discussed, and illustrated by some new experiments. Many others of these papers might be summarized, but only by exceeding the limits of a brief biographical sketch. SCIENTIFIC. 1.

Editor Popular Science Monthly : IN the recent controversy between Prof. Huxley and Dr. Wace, I was struck by the fact that the latter does not seem to have seen that the truth of the gospel narratives is not so much a matter of literary criticism as of psychological criticism. Though M. Itenan prove, with stronger arguments than Dr. Wace attributes to him, that the Gospel of St. Mark was written by an eye-witness, the doubt still remains as to whether the eye-witness could be trusted. We all know that even in this age, from which supersti- tion is supposed to have been eliminated, people can not always be trusted to give an exact account of what they have seen ; and how much more would this be likely to be true of the imaginative Oriental ! " All the vaporing," as Dr. Wace calls it, " about the great critical operation of the present centu- ry " in " Robert Elsmere " is in reference to this point, the value of human testimony — not whether such a one wrote at such a time, but just how much he was influenced, when he did write, by his psychological tendencies, and also by the traditions of which he, in common with his fellow-men, was the heir. When we find in the ancient religions of India, Persia, and Egypt exactly the same supernatural elements that we find in the gospel stories, and sometimes even a resem- blance in details, such as there is between certain points in the life of Krishna and of Christ, we can not help drawing the conclu- sion that these supernaturalisms were, in their essence, survivals from older religions, and, in their attachment to the life of Christ, were a proof of the psychological tendencies of the people of that time toward supernatu- ralism ; but that such conclusions should in any way affect the sincerity of Christ him- self is perfectly absurd. Dr. Wace thinks that, unless Christ were what he is claimed by orthodox Christians to be, he would be perjuring himself, for example, in the Lord's Prayer, by addressing " our Father," which must show that he was aware of a special connection between God and himself; it nei- ther shows a special connection nor hypoc- risy on the part of Christ, but is a most natural form of expression. Even in the hymns of the " Rig-Veda," probably forming the oldest book in the world, men worshiped Dyaus-Pitar (Heaven-Father), so the concep- tion of "our Father who art in heaven" is far older than the time of Christ. Through the unbiased study of comparative religion — a far better way to arrive at the truth than the study of literary criticism — the figure of Christ is made to stand out as the greatest revealer of absolute truth ; and the super- natural elements which have been welded into his gracious life, refined of trivialities which attached to them in other religions, are but the attempt of the human mind to clothe in fitting outward symbol the truth which springs from within. Helen A. Clarke. Philadelphia. WHY NOT "COBBLE-UP" THE HUMAN BODY? Editor Popular Science Monthly : The loud trumpeting of Dr. Brown-S6- quard's alleged discovery of an " elixir of life " suggests another still more rational and practicable way of securing immortality, accompanied by youth and beauty, which I am amazed that no eminent surgeon has as yet CORRESP ONDENGE. 121 made a bid for fame by proposing. We are all familiar with the brilliant feats of modem surgery in replacing damaged portions of the human body by sound and healthy parts obtained elsewhere. Autoplasty is one of the wide-reaching benefactions of science. Scalped mill-operatives have been furnished with good-as-nevv chcvelures by piecemeal contributions from the heads of accommo- dating friends. Mangled eyes have been successfully replaced by healthy ones taken from cats and rabbits. For centuries the victims of Oriental despotism have had their noses and ears restored by the skilled " leeches " of India, Turkey, and Persia. So common have become operations for the restoration of noses, eyelids, ears, lips, pal- ates, and tracheal, that each of these has re- ceived a distinct name in medical literature. Nor have the surgeons stopped with these external organs, but have boldly invaded the interior of the system ; and I think it is on record that one surgeon succeeded in saving his patient's life by patching up his caecum with the intestines of a sheep Why is not this idea capable of indefinite expansion ? We all know that, as a rule, men do not break down like the "Wonderful One-Hoss Shay," which " went to pieces all at once- All at once, and nothing first — Just as bubbles when they burst." Almost invariably they die from the wearing out or lesion of some one organ. Now, anatomists tell us that we have not a muscle, nerve, or organ which is not dupli- cated in some one of the lower animals. This being the case, what is to prevent the skillful surgeon, when he finds that one of his patient's viscera — cranial, thoracic, or abdominal — has become incapable of per- forming its functions, on account of wearing out or weakness, from removing it, and sub- stituting a brand-new one from some healthy and high-bred animal ? For example, instead of using the pan- creatic juice of the lower animals, as Dr. Brown-Sequard proposes, why not transplant the organ which produces it, and thus insure the patient a never-failing supply of the di- gestive fluid produced on the spot ? When a man's pancreas becomes debilitated from years of unremitting toil with fried pork and mince-pies, and goes on a strike, threatening stoppage of all other bodily functions and death, why not skillfully excise it, and put in its place, say, the pancreas of a goat or a pig ? The wound heals by first intention ; the man's digestion recovers the tone of his boyhood days ; the food his wife cooks tastes as well as " the things mother used to make " ; existence again becomes sweet mu- sic, and he takes a new lease of life, until some other organ breaks down, which can be similarly replaced. So, on the simple plan of the old lady who made a pair of stockings last a lifetime by knitting on new feet one year and new legs the next, men can readily attain the age of Methuselah, with no other drawbacks than periodic recoveries from surgical operations, which will be no worse than their customary "spells of fever," "attacks of indigestion," " nervous prostration," " malarial poison- ing," and the like. I have endeavored to treat this important subject with proper scientific gravity. I an- ticipate, however, the ghoulish glee of the professional humorist, who will gloat over the prospect of prominent citizens being al- luded to as " well-repaired " instead of " well- preserved" men, and who will give the over- worked stove-pipe, mother-in-law, and front gate a rest, in order to exploit the funny possibilities of a mature gentleman who has been patched up until he has the digestive apparatus of a goat, the vocal and respira- tory machinery of a donkey, and a cranial cavity filled with the ganglia of a sheep or an intelligent Newfoundland dog. I anticipate also the moral and scriptural objections of a part of the clergy, as to the effect upon the soul of this incorporation with the beasts of the field. But all great ideas must encounter this sort of thing, and so mine must perforce en- dure it. John McEluoy. Washington, D. C. THE EIGHT TO PEOPEETT. Editor Popular /Science Monthly : In Mr. Philpott's able essay on " The Origin of Property," in the " Monthly " for September, he quotes Prof. Leslie's notable remarks on the true meaning of the word " property." While there may have been others who have also called attention to the same point, I can not refrain from specially referring Mr. Philpott and your readers to Volume II of the works of the late Thomas Hill Green, a thinker whose acute and iucid discussion of fundamental political notions has received singularly inadequate notice. He frequently touches bottom ground with a firmness characteristic of no other political writer known to me, and in this instance he phrases with especial felicity (Vol. II, " Principles of Political Obligation," pp. 517 et seq.) the idea upheld by Mr. Philpott and Prof. Leslie : " Two questions are apt to be mixed up which ought to be kept dis- tinct. One is the question how men came to appropriate ; the other, the question how the idea of right has come to be associated with their appropriations. . . . One condi- tion of the existence of property, then, is appropriation. But another condition must be fulfilled in order to constitute property. This is the recognition by others of a man's appropriations as something which they will treat as his, not theirs, and the guarantee to him of his appropriations by means of that 122 THE POPULAR SCIENCE MONTHLY. recognition ... (p. 522). To say that it is a 'law of nature' that a man should have a property in the work of his hands, is no more than saying that that on which a man has imposed his labor is recognized by others as something which should be his, just as he is recognized by them as one that should be his own master. ... It is only within a so- ciety, as a relation between its members, that there can be such a thing as a right, and the right to free life rests on the com- mon will of society. Just as the recognized interest of a society constitutes for each member of it the right to free life, so it constitutes the right to the instruments of such life, and thus through the medium, first of custom, then of law, securing them to each." This is Prof. Leslie's thought in amplified form, and it may be of interest to Mr. Philpott to note the passage. John H. Wigmore. Cambridge, Mass., September 14, 1S89. EDITOR'S TABLE. A MINOR ITT BUT NOT A SECT. A PROTESTANT minister in Oak- land, Cal., in a recent address on the subject of the public - school system of the United States, expressed himself as follows : " In one of the schools of Sau Francisco Herbert Spen- cer's ' Data of Ethics ' was intro- duced as a text-book of morals — as palpable a violation of the law forbid- ding sectarian instruction as the intro- duction of the Catholic or Methodist catechism ; for Herbert Spencer belongs to that very small and narrow sect which promulgates the creed of agnosti- cism." If the reverend speaker had ta- ken the ground that the " Data of Eth- ics " was too abstruse a book to be placed in the hands of public-school pupils, we should have felt inclined to sustain his objection. But when he says that to introduce such a book is to give a secta- rian character to the school in which it is used, we must enter a protest. Sci- ence is never sectarian ; philosophy is never sectarian. Sectarian teaching be- gins when you ask a man or a child to assume what can not be proved, for the sake of keeping within the dogmatic lines that fence round some particular creed. The followers of Mr. Spencer may be a minority, but they are no more a sect than were the adherents of the Oopernican system of astronomy, or than are the believers in the Darwinian theory of natural selection. Mr. Spen- cer makes no appeal to faith, but finds his premises in the common experience of mankind. A pupil who was being taught out of the "Data of Ethics" would he quite at liberty to dispute either the premises or the arguments of the author ; and he would not he si- lenced by the declaration that Mr. Spen- cer was infallible. But when catechisms are taught they are taught, not as con- taining matter for discussion, but as containing doctrines that must not be disputed, on pain of more or less disa- greeable consequences. Similarly, when the Bible is read in school, it is read not as a fallible record of events or a fallible guide in morals, but as some- thing absolutely authoritative — the very voice of God. It is perfectly obvious, then, where sectarianism in education begins : it begins just at the point where doctrines of any kind, accepted on faith by a portion of the community and not discussible on grounds of reason, are made a part of public-school instruction. Sectarianism comes in whenever the teacher is obliged to say " Hush ! " to the inquiring scholar who wants his reason satisfied before he will believe. There is no sectarianism, on the other hand, in making use of a book which lays no claim to any kind of privilege, and which, therefore, can not force the belief of any one. The followers of Mr. Spencer do not form a sect, because they have no beliefs which they wish to ex- empt from criticism or discussion, and becauso they hold themselves at full lib- EDITOR'S TABLE. 123 erty to pass beyond the bounds of Mr. Spencer's thought whenever they can see their way to doing so. Mr. Spencer's " Data of Ethics " may not contain all the truth on the subject of morals, but the truth which it does contain lends itself to demonstration ; and no one can be the worse for being taught demonstra- ble truths. Upon that foundation he can afterward build what he likes — hay, stubble, or what not; and after his su- perstructure has been tried by the fire of experience, a3 it is very likely to be, he will still have something solid left on which to rebuild in perchance wiser fashion. We do not advocate the introduction of the "Data of Ethics" into the public schools; but we are con- vinced that it would be a very good thing for the rising generation if some of the ideas contained in that book could be brought home to their minds. SCIENCE IN DOMESTIC ECONOMY. Mr. Edwakd Atkinson's paper on " The Art of CookiDg," which opens this number of the " Monthly," is one to which we confidently call the atten- tion of every reader of the magazine. There is no art which concerns the well-being of more persons than cook- ery. Blunders in navigation do not in- jure those who stay on land, errors of engineering may easily be escaped, and the mistakes of the apothecary do not affect him who takes no medicine. But none of us can do without eating, and if our food is not properly prepared we are sure to suffer both in health and in pocket. The fact which Mr. Atkin- son states in his opening sentence, that "the cost of materials which are used for food comes to one half or more of the average income " of most persons, shows the importance of carefully lim- iting the percentage of waste in this large item of domestic expenditure ; and when we remember that, as he states in the next paragraph, " good health depends in greater measure upon ade- quate nutrition and upon the conversion of food material into a digestible form than upon any other factor in life," the value of correct principles in cookery, on the score of health, is apparent. Yet the present mode of cooking is far from agreeing with correct principles. Mr. Atkinson says that almost the whole of the fuel used in cooking in the ordinary way is wasted, while the odors which accompany the process are evi- dence that the food is losing nutritious properties, and often that it is being converted into an unwholesome condi- tion. The effect of heat on starch, su- gar, fats, and albuminoids, and the laws of radiation and conduction, are well enough understood, yet cookery has re- mained stagnant, while metallurgy, dye- ing, soap-making, and other familiar arts, which likewise depend on chem- istry and the science of heat, have made gratifying progress. The cooking of the world is practically in the hands of women, and the art is in an undeveloped state. Here is a chance for the sex to prove good their claim to the same men- tal capabilities as men. Let them give up blind following of recipes and learn to understand processes. Let them ex- periment, record observations, and in- vent. If they can not at once rise to the level of original work, let them at least study the investigations and apply the inventions of others. Mr. Atkinson has made experiments in cooking, ex- tending over some years, which have led to the invention of the apparatus described in his article. His " oven " and " cooker " unquestionably prevent the scorching of food, and effect a won- derful economy in fuel, yet he has found it difficult to give away his valuable ideas to the public. "We are confident, however, that his article will be read with more interest than, say, twenty years ago. A steadily growing amount of thought is being given to making science serviceable in the preparation of food, and in other matters of household economy. The fact that such men as 124 THE POPULAR SCIENCE MONTHLY. Mr. Atkinson and Prof. Mattieu Will- iams are working in this field, and that their results are received with interest, gives promise that the human race will some time attain to a thoroughly intelli- gent style of daily life. LITERARY NOTICES. The Structure and Distribution of Coral Reefs. By Charles Darwin. Third Edition, with an Appendix by Prof. T. G. Bonnet. With Illustrations, New York: D. Appleton & Co. Pp. 344. Price, $2. The formation of coral reefs was one of the subjects investigated by Darwin during the voyage of the Beagle. The information which he obtained from his own observations and the reports of other investigators, to- gether with the mode of accounting for these structures resulting from his study of this material, are embodied in the present work. The first edition of the book was published in 1842, a brief sketch of the author's views having been read in 1837 before the Geologi- cal Society, of London, and published. Dar- win's theory of coral reefs speedily won ac- ceptance among men of science, and had been taught in scientific lectures and text- books for a generation before any consider- able rival appeared. In 1874 Darwin issued a revision of his book, containing additional facts obtained by later explorers. The only important work on the subject which had appeared since 1842 was Prof. James D. Dana's " Corals and Coral Reefs," issued in 1872. Prof. Dana had accepted Darwin's theory in the main, though objecting very decidedly to some of its minor features. In 18S0 Mr. John Murray, one of the natural- ists of the Challenger Expedition, advanced a theory widely at variance with that of Darwin, which has found vigorous support- ers, and various modifications of both the leading hypotheses have been offered by later investigators. But the majority of those qualified to judge of this difficult question have shown a disinclination to give up Dar- win's theory for that of Murray — so much so that the Duke of Argyll, evidently jealous for Scottish honor, in 1887 accused scientific men of disregarding Murray's work from subserviency to their idolized Darwin. The duke's article was entitled " A Conspiracy of Silence," and drew forth a vigorous reply from Prof. Huxley in the review in which it appeared, besides arousing a spirited discus- sion in the columns of " Nature." The new edition of " Coral Reefs " affords the means of forming an intelligent opinion as to the merits of Darwin's views. It is, by the way, the first edition that has been published in this country. The body of the work has been left as revised by the author for the second edition, but occasional foot-notes, and an appendix comprising a careful summary of the more important memoirs published since 1874, have been added by Prof. T. G. Bonney. In the first three chapters the three chief classes of coral formations — atolls or lagoon islands, barrier reefs, and fringing or shore reefs — are described. The fourth chapter deals with the distribution of coral reefs and conditions favorable to their increase, their rate of growth, and the depths at which reef-building corals can live. Dar- win's theory of the formation of the differ- ent classes of coral reefs then follows. Coral polyps do not flourish below a depth of twenty or thirty fathoms, but reefs are found rising from much greater depths — how are these to be accounted for ? The theory re- gards barrier reefs and atolls as having been developed successively from fringing reefs. The latter are so named because they closely skirt the shores of islands and continental land, increasing by growth on the outer edge, where the conditions seem to be most favor- able for the life of the corals. Imagine such a reef formed around a volcanic island, and the island then to begin sinking beneath the sea. The reef will be carried down with it, but the active growth at the outer edge will still keep this part at the sea-level, while the inshore part where growth has stopped will become deeply submerged. We now have an island surrouuded by a deep channel, out- side of which is a ring of coral — that is, an island encircled by a barrier reef. Suppose the subsidence to go still further until the highest point of the island disappears, the growth at the outer edge of the reef still keeping it up to the surface, and there re- sults a ring-shaped reef inclosing a lagoon — that is, an atoll. It can not be denied that this theory accounts for the channel within a barrier reef and the ring shape of atolls, besides answering the question asked above, LITERARY NOTICES. 125 all in a very natural way. But it has been objected to on account of the amount of subsidence in the floor of the Pacific and Indian Oceans which it would imply, and for other reasons. Mr. Murray attempts to find a foundation at a suitable depth for the cor- als to begin work upon without supposing subsidence. He thinks this could be fur- nished by the accumulation of skeletons of minute animals and plants, upon natural ele- vations of the sea-floor, although when such remains fall to greater depths they are mostly dissolved by the aid of the carbon dioxide in the water. He thinks that a coral plantation rising on such a base would tend to assume the atoll form owing to the more abundant supply of food to the outer por- tions, and the removal of dead coral rock from the inner portions by the force of cur- rents and by solution. Ee believes that bar- rier reefs have been built out from the shore, and that the channel within them is hollowed out by the same agencies as the lagoon of an atoll. The death of Darwin occurred so soon after the promulgation of this theory that he did not have an oppor- tunity to publish any examination of it, but to a friend, Mr. T. Mellard Reade, who had expressed the opinion in a letter that it was " a very far-fetched idea," he replied : " I am not a fair judge, but I agree with you ex- actly that Murray's view is far-fetched. It is astonishing that there should be rapid disso- lution of carbonate of lime at great depths and near the surface, but not at intermedi- ate depths where he places his mountain- peaks." Besides a statement of Murray's theory, Prof. Bonney's appendix contains abstracts of the views of Alexander Agassiz, II. B. Guppy, G. C. Bourne, Bayley Balfour, W. 0. Crosby, and J. D. Dana, together with an expression of his own opinion as to the value of the various objections to Darwin's theory. The volume contains three folded charts, and has an adequate index. It is bound uniformly with the other works of Darwin issued by the same publishers. Natural Religion. ByF. MaxMulleu. Lon- don and New York : Longmans, Green & Co. Pp. 608. Price, $5. This book includes the first course of Gifford lectures, twenty in number, deliv- ered by Prof. Miiller before the University of Glasgow in 1888. The Gifford lectures rest upon a fund of eighty thousand pounds which was left by Lord Adam Gifford by will in 1885, to be applied in specific sums to the establishment in four Scotch universities of chairs for " Promoting, advancing, teaching, and diffusing the study of Natural Theology," or " the knowledge of God, the Infinite, the All, the first and only cause, . . . the knowl- edge of his nature and attributes, the knowl- edge of the relations which men and the whole universe bear to him, the knowledge of the nature and foundation of ethics or morals, and of all obligations and duties thence aris- ing." The will provided for changes of lect- urers at short intervals, so that the subject might be presented by different minds ; that no tests should be required of them save that they be " able, reverent men, true think- ers, sincere lovers of and earnest inquirers after truth " ; and that they should treat their subject as a strictly natural science, and under no restraint. Prof. Miiller's course naturally assumes the character of an introduction to the courses that are to follow. Much of it is therefore given to lay- ing down the lines and adjusting the bear- ings ; and the discussions comprised in it touch chiefly upon the three points of the definition of natural religion ; the proper method of its treatment ; and the materials available for its study. The definition is found in the seventh lecture to be, " Religion consists in the perception of the infinite un- der such manifestations as are able to in- fluence the moral character of man." Of methods, the historical is preferred as the one most likely to lead to results of perma- nent value. Its object is to connect the present with the past, to interpret the pres- ent by the past, and to discover, if possible, the solution of our present difficulties, by tracing them back to the causes from which they arose. It has to be, and is, defended against the common misapprehension that the historian cares only about facts, without attempting to interpret them ; and against the opposite school of philosophers who think that our own inner consciousness is the one and only source from which to draw a knowledge and understanding of natural re- ligion— forgetting that their inner conscious- ness " is but the surface of the human intel- lect, resting on stratum upon stratum of an- 126 THE POPULAR SCIENCE MONTHLY. cient thought, and often obscured by thick layers of dust and rubbish, formed of the detritus in the historical conflicts between truth and error." The materials for the study are language, myths, customs and laws, and sacred books. In pursuing it, the subject is divided into three branches, according as what is here called the Beyond or the Infinite was perceived, in nature — Physical religion, which was to be the sub- ject of the next course of lectures ; in man — Anthropological religion, which meets us again and again in different ages and in widely distant parts of the world ; or in the self — Psychological religion, filled with in- tellectual endeavors after that which lies be- yond man, as a self-conscious subject. The last statement corresponds in the Christian religion with the doctrine of the Holy Ghost, by which was meant in the beginning " the Spirit which unites all that is holy within man with the Holy of Holies, or the Infinite beyond the veil of the Ego, or of the merely phenomenal Self." A Manual of Machine Construction for Engineers, Draughtsmen, and Mechan- ics, EMBRACING EXAMPLES, RULES, TA- BLES, and References. By John Rich- ards. Philadelphia : J. B. Lippincott Company. Pp. 306. Price, $5. The author of this book enjoys the ad- vantage of an experience of thirty-five years in constructive engineering work, at home and abroad. He is a practical mechanic in metal and wood work, and a designer and constructor of machine-work of all kinds. He has prepared original designs for more than a thousand machines now in common use in America and Europe, and is the au- thor of many papers and a number of valu- able treatises on various mechanical subjects. The present work is practical ; is not for in- struction so much as for direct application, and is intended to meet the every-day wants of the engineer, draughtsman, and mechanic in his workshop. The tables are the result of actual practice, and are worked out from complete drawings. The references arc such as are constantly required in real work, and the selection is made by noting for a number of years the relative frequency of references to the different subjects. In points of mate- rial content and arrangement, each alternate page is left blank, so as to leave a place for receiving the owner's notes and original mat- ter, the constant accumulation of which will, it is believed, make the work a valuable vadc mecum. There are other conveniences in ar- rangement, designed to facilitate the use of the book and the finding of the page, besides helps to the reduction of values. In the gen- eral introductory observations, the possibil- ity of determining between what is comput- able and what not, is considered. Among the particular subjects of the chapters are : " Machine Design," " Bearings for Shafts and Spindles," "Sliding Bearings," "The Trans- mission of Power," etc., " Steam Machinery" with its details ; " Hydraulics," " Mechanical Draughting," " Heat," " Dynamics," " Prop- erties of Materials"; and "Weights, Meas- ures," etc. . The Federal Government of Switzerland. By Bernard Moses, Ph. D. Oakland, Cal. : Pacific Press Publishing Company. Pp. 256. Price, $1.50. This volume, by the Professor of Histo- ry and Political Economy in the University of California, comprises a carefully prepared essay on the Constitution of the principal established European republic ; one that may give lessons to American citizens, and which is in every way worthy of their study. Prof. Moses approaches the subject with the manner of one who understands it, and treats it philosophically and judiciously, not only describing the provisions of the Swiss Con- stitution, but investigating their evolution, and finding how they came to be there. In the introduction, having considered the phys- ical conditions of Switzerland and observed the composite character of its population, he draws a contrast between it and the American republics — the United States and those of Spanish origin. The population of Switzerland, various as it is, has grown from prehistoric stock without serious disturbing influences. The populations of the Ameri- can republics have been formed from ele- ments whose later environment has had little in common with their earlier surroundings, and under conditions where the force of an- cient traditions has been weakened by long migrations. Switzerland and the British colonies were predetermined to federation by their geographical positions. Switzerland is the only existing republic that has lived LITERARY NOTICES. 127 through the period in which religious wars were a part of the order of the day. Not- withstanding this, and the sharp religious divisions between the cantons, union has prevailed, and a federal government has been established under which both Catholics and Protestants live without serious friction. Another peculiar feature of Switzerland is the prevalence of three distinct and official languages (besides the unofficial Romansch), and the maintenance of as many national characteristics, while in the United States there is a tendency to assimilation in all things of thiskind. The negro in the South introduces a problem into our political life "of which the population of Switzerland gives no hint." Such class distinctions as may exist there are those that may arise in a homogeneous society under the conditions of modern life, or are a survival from the feudal age; but "they are not such as pro- ceed from the existence in the population of different races regarded as inferior and superior." Illiteracy and general ignorance in any part of the population are wanting in Switzerland ; " in fact, in no country of the world are the affairs of education adminis- tered more zealously or with greater effi- ciency. The problem of republican govern- ment is, therefore, simpler in Switzerland than in America, in spite of the proximity of the Swiss to the monarchical rule of Euro- pean states." The analysis of the Swiss Con- stitution is introduced by a review of the " Antecedents of Swiss Federalism," and is applied in succession to the several depart- ments of the government, its foreign and internal relations, the army and finance, "Rights and Privileges," and "The Com- mon Fraternity." Kant's Critical Philosophy for English Readers. A New and Completed Edition. By John P. Mahaffy, D. D., and John H. Bernard, B. L>. Vol. II. The Pro- legomena translated, with Notes and Ap- pendices. London and New York : Mac- millan & Co. Pp. 239. Price, $1.50. This is the second volume of a work whose first volume was noticed in this maga- zine several months ago. While in the pre- ceding part of this work the editor has taken the more agreeable task of paraphrasing the original, because the " Kritik" is already ac- cessible in English, he has deemed it " due to Kant to put his ' Prolegomena' in all their homeliness literally before the reader." He has reprinted in the appendix the suppressed passages of Kant's first edition of the " Kritik." The work is unfortunately with- out an index. TJie Modern Chess Instructor, Part I, by W. Steinitz (G. P. Putnam's Sons), contains elementary explanations for beginners, the description of notations, a telegraphic chess code, an essay on the principles of the game, and analyses of six popular openings, with illustrative games to each opening, while the appendix contains the games of the contest between Messrs. Steinitz and Tschigorin which were played at Havana in January and February, 1S89, with annotations by the author. Pp. 193. Price, $1.50. Prof. Charles W. Kent, of the Univer- sity of Tennessee, has prepared an edition of the old English poem Elcne, which is as- scribed to Cynewulf, with introduction, Latin original, notes, and a complete glossary. The introduction and notes are designed for the use of students, and not with any view to critical purposes. The glossary has been made more complete than is usual in edi- tions of old English poems. From the his- torical notice in the introduction, it appears that the manuscript of this poem was found in 1822 in the Cathedral Library in Vercelli, and the question of the way it got there has given rise to considerable discussion, with not very definite results. The author is sup- posed to have been a Northumbrian, and to have lived in the eighth century. The poem is founded on the story of the search for the cross and its discovery by the Era- press Helena, wife of Constantino. While the author has followed the story with con- siderable fidelity, he has not bound himself too closely to it, and those passages which are all his own are the best in the work. Besides the historical and critical introduc- tion, a metrical introduction and a bibliog- raphy are given. We last month published a notice of a translation of this and two other old English poems.

Lippincott Company) have been prepared to meet the necessities of a short course of seventy hours at the United States Military Academy. The selection of material has been guided by considerations of the sub-course of studies and of what is essential and most useful for the students to know. A logical arrangement is sought, and clearness and conciseness in relation are aimed at. Most of the experimental illustra- tions described or referred to are such as can be performed in the lecture-room. The special topics treated of are " Thermome- try," " Dilatation of Bodies," " Calorimetry," " Production and Condensation of Vapor," "Change of State," " Hygrometry," "Con- duction," " Eradiation," " Thermo - Dynam- ics," and the "Meteorological Aspects of Heat."

Blakiston, Son & Co., Philadelphia) is not designed to be a medical chemistry, but takes up those parts of general chemistry which it is necessary for medical students to know. The author, having prepared students for several years in this branch, believes that he knows their needs, and has made this effort, in the light of that knowl- edge, to supply them. Besides the elements, a large share of the space is allotted to the chemistry of water and air and the sub- stances by which they are polluted ; and for this acknowledgment is made to the lectures and articles of Prof. C. F. Chandler. A chapter is given to the tests for the impor- tant substances, and another chapter to the tests for urine and the substances that occur in it. The theories of to-day concerning chemical action arc briefly presented. The metric weights and measures are also no- ticed, and the rules are given for converting degrees of temperature. Pp. 154.

The Kingdom of the Unselfish ; or, the Empire of the Wise (Empire Book Bureau, 28 Lafayette Place, New York), has been written by Mr. John Lord Peck with ref- erence to the existing stage of social evo- lution. If not suited to the present state of opinion, it may find a reading in the next century. The purpose of the book is un- folded in the introductory chapter, which is headed " The Reliable and Unreliable in Thought." Of the unreliable are all relig- ious systems founded on tradition and revela- tion, dogma, and speculative philosophy, in- cluding all the systems that have followed one another from Plato and the ancients down to the pessimism of Schopenhauer and Hartmann and the agnosticism of Comte, Huxley, and Spencer. Neither of these last systems " is sufficiently near the final truth to long satisfy the human mind, and the prediction is here ventured that both of them will give way to a system of ontology LITERARY NOTICES. 129 more perfect than the evolution philosophy as represented by Herbert Spencer." The class of ideas that is most positive and re- liable is found in modern science, which ac- knowledges nothing as beyond candid criti- cism, has nothing sacred but the truth, and investigates every part of the universe and of man with equal impartiality ; and is not an extreme or antagonistic of all former knowledge and opinion, but " is a more com- plete, thorough, and systematic knowledge of the same kind as any imperfect knowl- edge preceding it that has a real basis of fact." The second volume of the Report for 1838 of the Geological Survey of Arkansas, under the direction of State Geologist John C. Branner, comprises a review of the Neo- zoic Geology of Southwestern Arkansas, by Robert T. Hill. It is the result of the joint work of the United States and the State Surveys, in which the latter was able to avail itself of Prof. Hill's knowledge of the mesozoic geology of other parts of the Union. The region embraced in the present survey may be said roughly to lie between the Oua- chita and Red Rivers, extending a little east of the Ouachita, including Little Missouri and Little Rivers, and to consist most large- ly of the Trinity, Lower and Upper Creta- ceous, and Tertiary formations, with plateau gravel and associated deposits, and the flood plains of the rivers, of the Post-tertiary or Quaternary. In determining the relations of the Upper Cretaceous beds, the author concludes that they are identical with those of Texas, more obscurely so with those of New Jersey, and the equivalent of the Upper Cretaceous of Europe. The relations of the Lower Cretaceous and Trinity with forma- tions east of the Mississippi are at present only conjectural. Prof. Hill's review is sup- plemented by papers on " The Northern Limits of the Mesozoic Rocks in Arkansas," by Prof. 0. P. Hay, and " On the Manufact- ure of Portland Cement," by Prof. Branner. — The third volume of the series is a pre- liminary report on the Geology of the Coal Regions, by Arthur Winslow. It contains only a part of the coal regions of the State, representing an area of nearly two thousand square miles and extending about seventy- five miles along the Arkansas River from the Indian Territory to Dardanelle. Chapters VOL. XXXVI. 9 are devoted to the "Distribution of the Coal," a review of the coal industry of the State, and the composition and adaptabilities of the coals. The Commissioner of Agriculture, in his Report for 1888, represents the year as hav- ing been one of much greater activity in the department than it had ever before experi- enced. The investigations made have ex- cited popular interest, and the results ob- tained have been helpful to the farming class. A good record was made of the work of the experiment stations. A clearing-house or exchange is called for through which they can co-operate. The most important duty devolving upon the Bureau was the work for eradicating contagious pleuro-pneumonia in cattle ; and, in connection with this, the need of a laboratory is suggested where persons can qualify themselves by experiment for practice in the diseases of animals. The division of entomology pursued investiga- tions on the cottony-cushion scale of Cali- fornia, the hop-louse, the root-infesting nema- tode worms, the cotton and boll worm, which attacked the tomato ; the Rocky Mountain locust, the buffalo gnat, and various other insects injurious to vegetation. It is giving attention to the introduction of parasites de- structive of such insects. Experiments of silk-culture have not yet given promise of a profitable industry. The chemical division interested itself in the study of food adul- terations and processes for making sugar from sorghum. The statistical department had to meet large demands for supplying information. The botanical division was busy in experiments on the adaptation of various plants, and in studies in vegetable pathology. Attention was given to the habits of different birds, and the depreda- tions on crops of various small mammals. The seed division was active in sending out seeds to experimental cultivators and the constituents of members of Congress. The forestry division reported progress, but not much encouragement as yet for the restora- tion of the forests, or even for the preserva- tion of what of them are left. Microscopical investigations were made in various direc- tions. In pomology experiments are report- ed on tropical and semitropical fruits and on hardy Russian fruits for the Northwest ; and an excellent paper, by Mr. W. n. Ragan, 130 THE POPULAR SCIENCE MONTHLY. is published on our wild fruits and the de- sirability and feasibility of perpetuating, cul- tivating, and improving them. Sun and Shade is the name of a monthly " picture periodical without letterpress," published by the Photo- Gravure Company, 853 Broadway, New York, which has lately completed its first year. In its growth it has found the taste of its patrons preferring pictures of the higher class, and quality rather than quantity, and announces its pur- pose in the selection of subjects to respond to this demand. Among its plans for the future are to reproduce the leading pictures in the collection of the Metropolitan Museum of Art and the works of American artists ; to encourage the artistic side of direct pho- tography in all its phases ; and to add exam- ples of sculpture, architecture, and indus- trial art. The subjects of " Ecce Homo," "The Return," "Sunshine," "From the Land of Sleepy Hollow," and others, in the August number, each executed in its peculiar style, could hardly be improved upon.

Sumichra « » SUSPENSION OF VITALITY IN ANIMALS. By M. VICTOE LAPOETE. FAMILIAR instances of suspended vitality, or rather latent vitality, are afforded by seeds, which may be kept for years without showing action, but are yet capable of being recalled to the exercise of the functions of life. Other instances are afforded by the lower organisms, which will remain dry and sterile for indefinite periods, to be brought into full activity at any time by supplying the due degree of moisture and warmth. Coming up to higher forms of life, the same phenomena are usually mani- fested in insects, one of the normal conditions of whose life — the nympha or chrysalis state — is characterized by the exhibition of the external appearance of death. During this stage the vital processes are tempered down till only enough are in effect to maintain a merely vegetative existence ; yet the insect is capable of slight motions when subjected to a shock or pressure. The duration of this apparent death varies according to the species and to external conditions. There are species that require two years of incubation before going through their metamorphosis. Others pass to tlie perfect state in a few days. Butterflies demand a certain degree of heat, below which they will not issue. The opening of the chrysalis takes place naturally when these atmos- pheric conditions are realized. If the season is late, the hatching is also late. Hence we can prolong the duration of the chrysalis state indefinitely by properly adjusting the temperature, delaying to that extent the metamorphosis of the imprisoned mummy into the free and winged insect. Reaumur, by putting chrysalides in an ice-box, was able to keep them alive and retard their develop- ment several years. " Perfect " insects are also capable of passing some time in a more or less definite condition of apparent death without losing the capacity to revive. I do not mean those simulations of death which some species put on in order to escape their enemies, and under which their condition may be mistaken by the most care- ful and patient observer, but cases in which they revive under really extraordinary conditions. Of such cases are instances of flies, which, having been accidentally inclosed in casks of Madeira VOL. XXXVI. 17 258 THE POPULAR SCIENCE MONTHLY. wine shipped to Europe, became lively as soon as they were ex- posed to the air. Frozen caterpillars are sometimes revived when thawed out. That May-bugs can be restored to life after they have been drowned has been proved by Prof. Balbiani, of the Col- lege de France, in conclusive experiments. He restored many by drying them in the sun after he had kept them immersed for twenty-four hours, two days, and even five days. In another experiment a stag-beetle, put under alcohol for a half -hour and then dried, was still in motion after three days. Going higher up in the animal series — eggs, which are analo- gous to the seeds of plants, present a remarkable example of re- tarded life. One of the most interesting features about them is the independence of their vitality, which persists even when the individual that has produced them, and within whose organism they are still contained, has ceased to live. This fact has been recognized in pisciculture, where artificial fecundation has been successful with eggs taken from dead fish. The persistence of life in frogs is very long. Spallanzani pre- served some frogs in a mass of snow for two years. They became dry, stiff, and almost friable, but a gradual heat brought them back to life. Vulpian observed a return of life in frogs and salamanders that had been poisoned with curare and nicotine. In both cases the animals in question had been for several days in the condition of cadavers. Toads have been shut up in blocks of plaster, and then, having been deprived of all air except what may penetrate through the material, and of all sources of food, resuscitated several years afterward. This question presents one of the most curious problems that biological science has been called on to explain. The longevity and vital resistance of toads are surprising. Besides the experiments we have cited, Nature sometimes presents some already made, and vastly more astonish- ing. Toads are said to have been found in rocks. Such cases are rare, but it would be as unreasonable to doubt them as to be- lieve in some of the miraculous explanations that have been made of the matter. The phenomenon is marvelous, it is true, but it is supported by evidence that we are not able to contest ; and skepticism, which is incompatible with science, will have to dis- appear if rigorous observation shall confirm it. The toad was observed, in one case, in the stone itself, and before, recovering from its long lethargy, it had made any motion. One of these toads was presented to an academy, with the stone which had served it as a coffin or habitation, and it was ascertained that the cavity seemed to correspond exactly with the dimensions and form of the animal. It is remarkable that these toad-stones are very hard and not at all porous, and show no signs of fissure. The mind, completely baffled in the presence of the fact, is equally SKETCH OF ROBERT KOCH. 259 embarrassed to explain how the toad could live in its singular prison and how it became shut up there. The strangest ideas have been expressed on this point. The ridiculous hypothesis has even been proposed of an imperceptible toad-germ that was de- veloped in the interior of the stone. The fact of the survival of the toad, despite the impenetrability of the stone, becomes less doubtful when we recollect the similar experiments on animals inclosed in plaster, which we have mentioned above. But the problem of the toad's introduction into the stone still remains un- solved. M. Charles Richet had occasion to study this question some months ago, and came to the conclusion that the fact was real, observing that even if, in the actual condition of science, certain phenomena were still inexplicable, we were not warranted in de- nying their existence, for new discoveries might at any time fur- nish an explanation of them. " The true may sometimes not be probable." But science takes accounting of the truth, not of the probability. Hibernating mammalia are capable of putting on all the appearance of death. The marmot, during its lethargic sleep, is cold, the temperature of its body being hardly 1° C. above that without. It respires only three times a minute ; and the beatings of the heart, which rise to ninety a minute in the active life of the animal, fall to ten in a minute. Bats, during the cold season, hang like dead bodies. One may take them in his hands, press them, and throw them into the air, without their manifesting any sign of feeling. — Translated for the Popular Science Monthly from La Monde de la Science et de V Industrie. SKETCH OF ROBERT KOCH. ONE of the most eminent of the colaborers of Pasteur in the investigation of the relations of microorganisms to disease- infection, and one whose labors have been most fully appreciated by intelligent men, is Dr. Robert Koch, of Berlin. He was born at Clausthal on the 11th of December, 1843, the son of a high officer in the department of mines. He attended the gymnasium in his native town, and afterward — from 1862 to 1866 — studied medicine at Gottingen. He became an assistant in the Allgemeine Krank- enhaus, or General Hospital, at Hamburg ; began the practice of medicine in 1866 at Langenhagen in Hanover ; then settled at Racknitz, in Posen. From 1872 till 1880 he was physihas or dis- trict physician at Wallstein, in the district of Bomst. He en- gaged in studies of bacteriological diseases, including wound- z6o THE POPULAR SCIENCE MONTHLY. infections, septicaemia, and anthrax, or splenic fever, with, great success ; and was appointed in 1880 a member in ordinary of the Imperial Health Office. In 1885 he was appointed a j>rofessor, and the director of the Hygienic Institute in Berlin. The first public report of Dr. Koch's to attract general atten- tion was that in reference to the bacterium which had been found associated with anthrax, or splenic disease, and was made about 1878. His investigations went to show that the potency of this organism lay in the spores rather than in the developed bacterium. He found that, when no spores were visible in the dried diseased blood with which mice were inoculated, the power of conveying infection lasted only for a few weeks ; while blood in which the spores had separated continued virulent for at least four years. He next turned his attention to those infectious disorders which originate in the introduction of poisonous matter through wounds. Living organisms had already been observed in these diseases, but their connection with the development of the infec- tion had not been determined. Dr. Koch's experiments with small animals showed that different forms of disease were pro- duced by the injection of putrid blood, one of which was not accompanied by the development of bacteria, but seemed due to a special poison which he named septin or sepsin, while another form was evidently bacterial; and that the effects varied with different animals. In 1882 Dr. Koch published the results of experiments which went to confirm the opinion already held by physicians who had observed the progress of the discovery of the fungoid origin of various infections, that tubercular disease was also caused by microphytic germs. He claimed not only that he had ascertained the bacterial origin of the disease, but to have detected the specific microbe, having found a characteristic and previously unknown bacillus in all tubercularly altered organs. He had observed it in pulmonary tuberculosis, cheesy bronchitis and pneumonia, tuber- cles of the brain, intestinal tubercles, scrofulous glands, and fun- gous inflammation of the joints ; in all cases which he had exam- ined of spontaneous consumption in animals — in cattle, hogs, poultry, monkeys, porpoises, and rabbits. In monkeys dead of consumption he had found the organisms in quanities pervading the lungs, spleen, liver, diaphragm, and lymphatic glands. He supposed that, escaping into the air from the expectorations of phthisical patients, they were inhaled into the lungs, where they developed. "Whenever the tubercular process was in its early and active stage, they were present in great numbers. When the climax of the tubercular eruption was passed, they decreased and might totally disappear. Dr. Koch's report of this investigation was published in one of SKETCH OF ROBERT KOCH. 261 the Berlin medical journals, in a memoir on " The Etiology of Tuberculosis," of which Dr. Klein, a distinguished pathologist, said that any one who carefully reviewed it would " come to the conclusion that Dr. Koch's results are to be accepted with uncon- ditional faith, and I have no manner of doubt will be considered by all pathologists as of the very highest importance. To those who are familiar with Dr. Koch's previous work, especially that on the etiology of splenic fever, or anthrax, and his observations on path- ogenic bacteria, this last work of his, on the etiology of tubercu- losis, will be an additional and brilliant testimony to his ingenious and successful method of research." This testimony is the more significant because Dr. Klein afterward disputed Koch's identifi- cation of the "comma bacillus" with the cause of cholera. In the next year a report was published by Mr. Watson Cheyne of a visit which he had made as a commissioner of the British Asso- ciation for the Advancement of Medicine by Research, to the labo- ratory of Dr. Koch, and also to that of M. Toussaint, who was engaged in a similar investigation. It represented that such results of Toussaint as disagreed with those obtained by Dr. Koch were not borne out. But the result of inoculation with cultivations obtained from Dr. Koch was in all cases rapid devel- opment of tuberculosis. The examination of a large quantity of tuberculous material showed the constant presence of tuber- cle bacilli, but of no other micro-organisms. The rapidity and certainty of action of this matter, when inoculated into animals, was in direct ratio to the number of bacilli introduced, and the most certain and rapid means of inducing tuberculosis seemed to be the inoculation of the tubercle bacillus cultivated on solid blood-serum. These facts led Mr. Cheyne to the conclusion that these bacilli are the virus of the acute tuberculosis caused in ani- mals by inoculation. When the cholera broke out in Egypt in 1883, the German Government appointed Dr. Koch chief of a commission to go to that country, and also to India, for the purpose of watching the course of the epidemic and investigating the nature and cause of the disease. The report of the work of this commission in Egypt, published in the early autumn of 1883, while it did not make known any certain results of the investigation, and dealt " in a very guarded manner " with the question of the discovery of a definite cholera bacillus, pointed out the line on which future studies were to be pursued. In experiments carried on in both living and dead subjects, while no distinct organism could be traced in the blood and the organs which are most frequently the seat of micro-parasites, bacteria having distinct characteristics were found in the intestines and their mucous linings, under cir- cumstances that seemed to identify them with the disease from 262 THE POPULAR SCIENCE MONTHLY. which the patients were suffering. They were present in the case of all patients suffering from cholera, and in the bodies of all who had died of it, whereas they were absent in the case of one patient who had had time to recover from cholera, but had died of some secondary complication ; and they were not discoverable in the case of patients who, during the cholera epidemic, succumbed to other diseases. They were also the same with the bacillus which Dr. Koch had met the year before in the bodies of patients who had died of cholera in India. From these causes the commission felt justified in provisionally holding the belief that those bacilli were in some way related to cholera, but were not yet prepared to say whether they were the cause or the effect of the disease. In 1884 Dr. Koch visited Toulon, where cholera was raging, partly at the wish of the French Government, which desired to know more of his methods of investigating and suppressing the disease. The investigations of the German commission were continued in India, and Dr. Koch's report on the subject was published in the " Klinische Wochenschrift," of Berlin, No. xxxiv, 1884. He had found, in the rice-water discharges of patients suffering from cholera, besides the micrococci and bacilli common to the evacuations of other patients, peculiar curved bacteria, which have become known as " comma-shaped " bacilli, such as he had not been able to discover in any cases of diarrhoea ; and he had succeeded in isolating them by artificial culture. This he declared to be a specific micro-organism having marked characteristics distinguishing it from all other known organisms. These or- ganisms grow rapidly in meat-infusion and blood-serum, and well in other fluids, especially milk, and in potatoes ; and possess the power of active motion. They grow best at a temperature of between 30° and 40° C, and cease to grow at 16° C, but are not killed by freezing. They grow only in the presence of oxygen, and very fast ; their vegetation rapidly reaches its highest point, then remains stationary for a time, after which it ceases as rap- idly as it grew, and the bacilli die. When dried, they die within three hours ; and they do not form spores. Micro-organisms pos- sessing all of these and certain more delicate characteristics which are definitely described, are Koch's bacilli ; organisms presenting only some of the characteristics, such as microscopical appear- ance, are something else. The presence of these bacilli in cholera, which was represented as universal, was determined by microscopical examination in ten cases in Egypt, and by microscopical examination and cultivation in gelatinous meat-infusion in forty-two cases of post-mortem ex- amination in India ; and in numerous other cases of dejections in Egypt, India, and Toulon — giving a hundred cases occurring in various parts of the world, carefully examined, in which the SKETCH OF ROBERT K0C11. 263 organisms were found. It had been further found that this was the only form of micro-organism that was constantly present in the disease ; that it was present in greatest numbers in acute and uncomplicated cases, and in the parts most affected ; while it was never present in other diseases, in healthy persons, and had not been found outside of the body where no cholera was in the neighbor- hood. Then, having disposed of two hypothetical presumptions of contrary tenor, Dr. Koch declared that no other conclusion could be arrived at than that these bacilli are the cause of cholera. Although no effects had then been obtained from experiments with comma bacillus upon animals, and direct experiments upon man could not be performed, various observations confirming the theory had been obtained which were almost as good as experi- ments on man. In the water of a tank whence the inhabitants of a village near Calcutta derived their supplies for drinking, chol- era bacilli were found in considerable numbers when the cholera epidemic was at its height. At a later period, when there were only a few cases of illness, the comma bacilli were few in number, and found only at one part of the tank. This was the only in- stance in which these bacilli were found outside of the body. Finally, Dr. Koch maintained that the natural history of the dis- ease corresponds with the various characteristics of the organism in question The bacilli grow rapidly, soon reach their highest point of development, then die, in correspondence with what oc- curs in the intestinal canal. Under ordinary circumstances the bacilli are destroyed in the healthy stomach, while persons suffer- ing already from some disorder of the stomach are most liable to be attacked with cholera. Lastly, the disease dies out in places where the conditions for its continuance are unfavorable ; as bacilli that have no spores will speedily disappear. In experi- ments subsequent to this report, Dr. Koch succeeded in producing cholera by inoculation in some of the smaller animals. Dr. Koch's conclusions were contested and some of his evi- dences were disputed by a French commission appointed to in- quire into the causes of cholera ; by certain English pathologists, including Dr. Klein and Dr. Lewis, of Netley ; and were not fully supported by an English commission in India ; but, while they may not yet have been fully accepted, they have not been overthrown, nor do they seem to have lost ground. A bill was unanimously passed by the German Parliament, in 1884, awarding a sum of 135,000 marks to Dr. Koch and his companions in this research. The principal published works of Dr. Koch are " Etiology of Splenic Fever," 187G ; " Researches on Diseases of Wound-Infec- tions," 1878 ; " Inoculation for Splenic Fever," 1882 ; " Contribu- tions to the Etiology of Tuberculosis," 1882 ; and contributions to the transactions of the German Imperial Health Bureau. 264 THE POPULAR SCIENCE MONTHLY. EDITOR'S TABLE. EVER Y-DA T SCIENCE. IF, on the one hand, we have fre- quent cause for astonishment at the rapidity with which modern life is be- ing transformed under the influence of scientific invention and discovery, we are, on the other, sometimes compelled to wonder at the extreme slowness with which certain useful and entirely prac- ticable reforms, plainly indicated by acknowledged scientific principles, are adopted by the public. There is a law in these matters which has perhaps never been very clearly formulated, but which it would certainly be desirable to under- stand. The telephone makes its way everywhere without pause or check, and the same is true of electric lighting and traction; while scientific cookery, though its general principles may be said to be fully established, lags pain- fully behind. That the latter is a mat- ter of the utmost importance, economi- cally and hygienically considered, needs no laborious demonstration ; yet how to interest the public in it seems to be a most difficult problem. People who go wild over the New Jerusalem of " Look- ing Backward " listen with cold indif- ference when it is explained to them how they can introduce here and now a most important amelioration in their own lives by economizing at once their worldly substance and the wear and tear of their physical organs. The fact that the reform in question would be par- ticularly beneficial to the so-called "working classes" fails to commend it to those who want a revolution or noth- ing. It is probably the case that men in general are more interested in spend- ing than in saving, just as they have more admiration to bestow on a great warrior than on a great philanthropist; and that, consequently, inventions that represent and call for expenditure are more attractive than those which sim- ply promote economy. More than one modern " improvement," we doubt not, has been adopted by many, as much from the pleasure of spending and — per- haps a more potent consideration still — of appearing to be able to spend the money required to procure it, as from a sense of its utility. However this may be, and whatever the law may be which regulates public interest in the practical applications of science, there can be no doubt that re- form in culinary operations is deserving of far more attention than it has hith- erto received. As we showed last month, it deals with a prime — may we not say the prime ? — necessity of hu- man life. It undertakes to substitute for a wasteful and hurtful empiricism in diet a scientific, economical, and wholesome method of preparing food for consumption. It shows us how we may save our pockets, how we may save our tissues, how we may lengthen our lives, and how we may increase our enjoyments. It promises to improve our tempers by decreasing the internal friction of our physical systems ; and, of course, decrease of internal friction means increase in our efficiency for all good purposes. Unlike some reforms that exist only on paper, and that at- tract sentimental people for the very reason that they are never likely to have more than a paper basis, this particular reform has been tried and realized. Its results are known and can be exhibited at any moment. "What is now required is that people should be persuaded that the thing is worth doing, and should be roused to shake off that lazy love of established routine which alone stands in the way of their doing it. The ordina- ry cooking-stove has so long been a kind of domestic Joss that its worship is hard EDITOR'S TABLE. 265 to overthrow. That it is not a purely- beneficent divinity many a sweltering attendant and many a dyspeptic par- taker at the altar are prepared to at- test; but pure beneficence, as every one knows, is not a quality that votaries always exact of their deities. Thus, just as long ago, at Ephesus, there were shrine - makers who stoutly withstood the new-fangled ideas broached by Paul, so to-day there are shrine - makers — i. e., stove - makers — who can not be expected to take very kindly to the ideas of our modern apostles of scien- tific cookery. We can not blame them if they are not in a hurry to break their molds and send their castings to the junk-shop ; but, all the same, a reform so deeply founded in common sense must come in time, and it would be well to prepare for its coming by gradually approximating to the type of cooking apparatus required. It is not in the matter of cookery alone that science is prepared to lend a helping hand in every-day life. There are a hundred reforms remaining to be accomplished, each one of which would do something to make our lives more worthy of rational beings. The most important and beneficent ones are those that can only be wrought by the earnest co-operation of each individual. "What we have to do is to see that a duty lies in making the most of our knowledge ; and it can nowhere be caused to yield a larger return than in its application to those ordinary affairs of life with which all are concerned. A COMPARISON IN RACIAL DEVELOP- MENTS. Colonel Garriok Malleet's ad- dress on " Israelite and Indian," which is concluded in this number of the "Monthly," presents an unusually lucid and interesting study in comparative civilization and religion. The author's purpose in selecting these two particu- lar peoples for comparison is, as he declares in the beginning, not because there is any special resemblance be- tween them more than between any two other peoples at corresponding stages of civilization, but because they offer convenient types illustrative of a general principle. We are familiar with both — with the Israelites, through the universal habitual study of the Bible; aud with the Indians, by virtue of our historical intercourse with them ; and the illustrative incidents do not have to be explained, as they would be in the case of any other two peoples that might have been selected. The princi- ple, which has been reached by anthro- pologists and students of religion gen- erally, and is admitted by many emi- nent theologians — that religion is a thing of growth, and subject to con- tinual development and refinement, and keeping pace with the advance of each nation in civilization and knowledge — is well set forth in the examples cited. The article bears the marks throughout that the author has studied the subject carefully and to the bottom. On the Israelite side he displays a critical knowledge of the Bible and the envi- ronment within which it was composed ; besides which, he has brought to bear upon his argument the results of the investigations of that band of eminent scholars whose conclusions, under the name of the "higher criticism," have deeply moved the theological world. On the Indian side, he is at home in his own special field of research. Taking the two peoples at those periods in their history when they had reached nearly equivalent stages in civilization, he holds up the parallelisms in their re- ligious opinions, particularly their ideas of God and a future state, their myths and their social usages, which, he as- sumes, were not peculiar to them, but could be found also among other bodies of people in the same stages of culture. That similar parallelisms are to be found among other nations of like civilization is a fact familiar to students of Oriental archaeology. 266 THE POPULAR SCIENCE MONTHLY. The weight of interest will center upon Colonel Mallery's demonstration that the Israelites, at the period under examination, were polytheists. The interest is heightened by the appear- ance, in the "Jewish Quarterly Re- view" (London) for October, 1889, of a learned and exhaustive article by the Rev. Prof. A. H. Sayce, under the title " Polytheism in Primitive Israel," which comes to the same conclusion. Most of the points mentioned by Colonel Mallery in this regard are also brought out by Prof. Sayce, of course independ- ently and with much greater elabora- tion. Some of his more striking pas- pages may be quoted. He speaks of " the Israelites who first ventured to use the plural Elohim of their national God," and adds : " The fact that the Israelites never forgot that it [Elohim] was a plu- ral term, that up to tlie last they often employed it in a plural sense, proves that the earliest users of it were wor shipers of many deities. . . . We may gather from the history of Micah, in Judges xviii, that the worship of the teraphim was the necessary accompani- ment of the tribal worship of Yahveh, as represented by a 'carved image,' and in the case of the tribe of Dan, at all events, it lasted ' until the day of the captivity.' . . . Yahveh was not yet conceived of as the sole god. ... It was in Judah that the older cult first died out of the popular belief. After the division of the kingdom, Judah with its central capital at Jerusalem formed a compact and organized community, in which the earlier tribal distinctions which had marked it off from Simeon, or Dan and Benjamin, were soon oblit- erated. The dynasty of David welded the community together, and the Temple of Solomon became more and more the center of the common faith. The wor- ship that was carried on in it, the belief of which it was the outward expression, the religious teaching and influence which emanated from it, gradually af- fected the ideas and convictions of the Jewish people. A time came at length when Josiah could venture to destroy the ' high places ' where the old local cults had been carried on for unnum- bered generations, and order his subjects to ' worship before the altar ' at Jerusa- lem alone." Prof. Sayce also denies that the Semites were fundamentally mono- theistic. This publication by one of the most learned of living Oriental scholars, who is a professor in the University of Ox- ford and a clergyman of the Church of England, is important as corroborating the statements of fact from which Colo- nel Mallery has drawn anthropologic lessons. LITERARY NOTICES. Scientific Papers of Asa Grav. Selected by Charles Sprague Sargent. Boston and New York : Houghton, Mifflin & Co. 2 vols. Pp. 397 and 503. Price, $3 each. The literary value of the papers contained in these volumes is equal to their scientific value, and that is well understood. Botani- cal criticism and description are not usually classed among literary subjects, but Prof. Gray made them one ; and a large proportion of what he has written in that field is aestheti- cally enjoyable. The period of his scientific writing lasted fifty-three years — from 1834 to 1887 — and during that time he made a re- markable number and variety of contribu- tions, all stamped with evidence of thorough- ness and the complete familiarity with his subject that seem to have been habitual with him. His writings are grouped by Mr. Sargent in four divisions. The first in im- portance contains his contributions to de- scriptive botany, relating chiefly to the flora of North America ; (i and although," says the editor, " it did not fall to his lot . . . to elab- orate any one of the great families of plants, the extent and character of his contributions to systematic botany will place his name among those of the masters of the science." Next in importance are his educational works, manuals or text-books, the influence of which on the development of botanical knowledge in this country has been great. The third LITERARY NOTICES. 267 group includes a series of critical reviews of important scientific publications, and of his- torical accounts of the lives and labors of workers in botany ; and the fourth group a number of papers which owe their existence to the discussions that followed the publica- tion of Darwin's " Origin of Species." The present volumes contain a selection of papers from the third group, with a few essays on subjects of general interest to botanists. Most of these papers, unlike those of the other groups, which are still in the market, have long been out of print, and have not been incorporated in any recent publication. The selections have been made with the thought of presenting, as far as might be, a view of the growth of botanical science during the fifty years through which the papers run — a period which, as the editor observes, is marked by the gradual change of ideas among naturalists upon the origin and fixity of species that has broadened the field of all biological investigation. The period was also characterized by a great in- crease and diffusion of the knowledge of botany in the United States, and by the growth of a body of earnest, energetic Ameri- can botanists, who have not only given vigor to the study and inspired interest in it through all the schools, but have also con- tributed to exalt the reputation of American science; and these botanists are, and are what they are, almost wholly by reason of what Prof. Gray and his books taught them. A glimpse of the condition of botanical study in the United States at the beginning of Prof. Gray's fifty years is afforded in the first of the papers, which is a review of the second edition of Lindley's " Natural System of Botany," published in 1836-'37. The inti- mation that " we do not intend to engage in a defense of what is called the natural system of botany " indicates that that system had not yet fully conquered acceptance. Still, the author assumed that the science could by no other method be successfully and philo- sophically pursued, and added: "The few persons who remain at this day unconvinced of its advantages are not likely to be affect- ed by any arguments that we could adduce. A somewhat larger number may perhaps be found in this country who admit the impor- tance and utility of the natural arrangement in the abstract, but decline to avail them- selves of the advantages it affords in the study of plants, because, forsooth, it is too much trouble to acquire the enlarged views of vegetable structure which arc necessary for the application of its principles." But the system had grown in favor during the preceding six years. Twenty years later, in the review of Henfrey's " Botany," 185*7, we are given this picture of the condition of botanical instruction here : " While in Eng- land botany is scarcely an academical study, here it pertains to collegiate and academical instruction where it is taught at all. In Europe not even an apothecary can be licensed without passing an examination in botany ; in the United States, we believe, it forms no part, at least no regular part, of the medical curriculum ; no medical school has a botanical chair; and no knowledge whatever of the science of the vegetable kingdom, which supplies the materia medica, is required for the degree of Doctor in Medi- cine ! " With botanical chairs in a large number of our leading universities and schools, filled by experts who are engaged in original work and encourage it in their stu- dents ; and pupils in high schools knowing more of the structure and qualities of plants than the doctors Prof. Gray describes, we of the present time have no reason to be ashamed of the advance that has been made. From these almost elementary considerations, the reviews and essays follow the series of publi- cations in the science and the course of dis- cussion over the whole scientific world, while having an eye primarily to America, includ- ing such subjects as Van Mold's observations of the cell ; De Candolle's theories of varia- tion and distribution and of the origin of cultivated plants, in reviewing which the author displays the sharpness of his discern- ment and the thoroughness of his knowledge regarding American plants ; Radlkofer's and Henslow's studies in fertilization ; the prin- ciples of nomenclature and the definition of species ; several local floras and special studies, never forgetting those that are pri- marily of American interest ; and those studies in which Prof. Gray so greatly sup- ported and aided Darwin, relative to variation and the origin of species. In these notices, while some of them seem to bristle with technicalities and run to details, the techni- 268 THE POPULAR SCIENCE MONTHLY. calities and details are never all, and are seldom a prominent feature. A lesson of general application is to be drawn in each of them, and is drawn and presented with such directness and lucidity that even young stu- dents can comprehend it and be interested in it. The essays in the second volume are more extended discussions of special topics, among which are " The Longevity of Trees," " The Sequoia and its History," " Do Varieties wear out, or tend to wear out ? " " Forest Geology and Archaeology," " The Pertinacity and Predominance of Weeds," and two on the flora of North America. Many of these papers, as well as no small number of the " Reviews," had not Prof. Gray been so pre- eminently a man of science, might have estab- lished his reputation as a literary essayist of the first rank. In some of them the author co-opeiates with Heer and De Saporta, an- ticipating the chief publications of the latter author, in working out the theory of the arctic origin of the plants of the temperate zone. " Notes on a Botanical Excursion to the Mountains of North Carolina " is a letter to Hooker, recording the experiences and observations acquired in a visit to a region which was of peculiar interest at the time, and is equally so now, on account of the number and variety of rare plants to be found there. This excursion seems to have been an exception to the general course of Prof. Gray's life ; for, in an address at the American Association meeting in 18*72, on " The Sequoia and its History," when he had just visited a unique botanical region in California, he says that, so far as our country was concerned, he had been to a great extent a closet botanist, and had not before seen the Mississippi or set foot upon a prairie. Through all of these papers Prof. Gray's style is clear ; he goes directly for the point ; is judicially minded ; always at home, search- ing in criticism ; and sometimes, as when dealing with Mr. Ruskin or exposing an er- ror of the authors on whom Henfrey relics, keen in sarcasm. And the editor's observa- tion that " his reviews represented the opin- ion of a just and discriminating mind, thor- oughly familiar with all sides of the ques- tion before it, critical rather than laudatory, loving the truth and its investigators, but the truth above everything else," is fully borne out. Sixth Annual Report of the Bureau of Ethnology, 1884-'S5. By J. W. Pow- ell, Director. Washington : Govern- ment Printing-Orflce. Pp. lviii + 675. It is impossible to examine one of these handsome volumes without being deeply im- pressed by the extent of the work that is being done and the interest of the store of information that is being secured by this bu- reau. The report of the director states that the field-work of the year comprised mound explorations by several assistants under the charge of Prof. Cyrus Thomas ; researches in the ancient ruins of the Southwest by parties in charge of Mr. James Stevenson and Mr. Victor Mindeleff; linguistic field-work by Mrs. Erminnie A. Smith, Mr. H. W. Hen- shaw, Mr. A. S. Gatschet, Rev. J. Owen Dorsey, and Mr. Jeremiah Curtin. Gen- eral ethnological investigations in the field were carried on by Dr. Washington Mat- thews, Dr. H. C. Yarrow, and Dr. W. J. Hoff- man. Office work on sign-language and pic- tographs was continued by Colonel Garrick Mallery ; on bibliography of North American languages, by Mr. James C. Pilling ; on the myths and customs of the Zufii, by Mr. Frank H. Cushing; on ceramics, by Mr. W. H. Holmes ; on a historical atlas of Indian con- cessions, by Mr. Charles C. Royce ; and by the explorers above mentioned, on their several specialties, when not engaged in field-work. The first of the papers accompanying the report is on " Ancient Art of the Province of Chiriqui, Colombia," by William H. Holmes, and is based on the large collection of archaeologic material from the province in the National Museum. The paper con- tains a wealth of information in regard to the works of the ancient inhabitants of this interesting region, and its descriptions are assisted by 286 illustrations. A curious feature of the Chiriquian objects buried with the dead is that they appear to have been made for that purpose, and not for use by the living. Another paper by Mr. Holmes is " A Study of the Textile Art in its Rela- tion to the Development of Form and Orna- ment." Mr. Holmes gives an instructive analysis of the forces and influences inherent in the textile art, the first lessons of which are order, uniformity, and symmetry. He discusses the influence of textile ornament upon other forms of art, such as architect- LITERARY NOTICES. 269 ure and sculpture, and also the manner in which intrinsic decorative elements are re- modeled in accordance with the rules of text- ile combination. The paper is illustrated with 73 figures. Prof. Cyrus Thomas supple- ments his former publications on American palteeographic literature with " Aids to the Study of the Maya Codices," embodying some original discoveries, and some explanations not already brought forward. Plates 50 to 58 of the Dresden Codex, and portions of other plates of the Dresden and other cod- ices, are figured in the text. Rev. J. Owen Dorsey furnishes an account of a secret so- ciety of seven degrees, still existing among the Osage, in which the traditions of the people have been preserved. This is accom- panied by two of these traditions in the original language, which he has succeeded in obtaining, together with an interlinear and a free translation of each, with explanatory remarks. An extended account of "The Central Eskimo " is contributed by Dr. Franz Boas, who spent a considerable time among these people in the region between Hudson and Baffin Bays. The scope of the paper includes the topography of the region, the distribution, tribal divisions, and numbers of the inhabitants, their habits and customs, their religious practices and beliefs, with translations of their myths and legends, and descriptions of their peculiar and ingenious weapons, implements, and utensils. Much work of previous explorers has also been incorporated with the original material in this account. The paper is illustrated with 156 figures and nine plates, two of the lat- ter being folded maps and six representing Eskimo drawings or carvings. A feature of the paper is the notation of a number of Eskimo songs. Catalogue of Canadian Plants. Parts I to IV. By John Macoun, M.A., F. L. S., F. R. S. O, Naturalist to the Geological and Natural History Survey of Canada. Recent years have brought to the botany of North America few contributions more valuable than the " Catalogue of Canadian Plants," by Prof. Macoun. The entire work has been issued within the past six years, the first part appearing in 1883, the fourth in 1S88, and only recently distributed; but these six years bear only small proportion to the actual amount of time the work has cost. Prof. Macoun gives us the labor of a life. For nearly forty years he has been an indefatigable explorer and systematist, pur- suing his investigations from Newfoundland to Vancouver's, from the Lakes to the Arctic Circle. The plan of the work contemplates an exact enumeration of the vegetable life of the Dominion, but virtually the plants of all northern North America are included, Alaska and even Greenland not being for- gotten. For this area not only is each spe- cies named, but for each, to the extent of present knowledge, is given its geographical range as well, its distribution, also its syn- onymy, and, in many cases, notes concern- ing habit and habitat. Facts of distribution are given with unusual exactness. For every plant each station is named and the name of the collector given, so that the catalogue is no mere check-list, but in so far an au- thentic geographical botany. It were a pleasing task, did the limits of this review permit, to notice at length many of the interesting points which this catalogue brings to light. Each specialist will, of course, scan the field in search of his own particular favorites, but every one at all familiar with North American botany will enjoy tracing the distribution of some of our more common or interesting forms. The common quaking asp (Populus tremuloides), for example, occupies the whole Northwest, from Labrador to Alaska. The sundew (Dro- sera rotundifolia), common in New England, but a plant which many a Western botanist has vainly desired to see, is reported common from Newfoundland west to the Pacific, and north to the Arctic Sea. Dodccathcon Meadia likewise runs north and west, and shoots its dainty stars in far Alaska, while plumes of Hordeum jubatum wave on the banks of the Mackenzie and Yukon. Few trees cross the continent from east to west. The paper birch {Betula papyrifcra) is one. With this may be named Picea alba and Picea nigra. These two spruces start together in New- foundland and extend westward across the continent side by side, until the former is re- placed in Columbia by P. Engelmanii, with which in the Athabascan region it seems to blend, while the latter (P. nigra) drifts north- ward, until it finally vanishes side by side with the paper birch hard by the waters of 270 THE POPULAR SCIENCE MONTHLY. the northern sea. All the species that pass from east to west seem to be northern forms. Lonicera involucrata, however, crosses the continent from New Brunswick to the sea- level of the Pacific coast. Very few plants whose center of distribution is west of the Rocky Mountains appear in the flora of the East. Pseudotsuga Douglasii comes as far east as longitude 114°; Pinus Murrayana, longitude 110°; Rubus nutkanus reaches Sault Ste. Marie, and Gojdyera Menziesii the shores of Lake Ontario. Some species which in those northern regions bind the floras east and west will interest naturalists generally by reason of peculiarly isolated distribution. Thus, Ar- meria vulgaris, common on sea-shores around the entire North, is found in profusion on the summit of Mount Albert, Gaspe. Vac- cinium ovalifolium, reported in the United States from a single locality on the south shore of Lake Superior, occurs at many stations in the far Northwest and also on the summit of Mount Albert. Galium kamt- schaticum, another arctic species, occupies the same interesting locality. Heliotropium curassavicum, characteristic rather of our Southern flora, surprises us by appearing abundantly away north and west of the Sas- katchewan. Six parts will show this excellent cata- logue complete. Of these, the four already published are devoted to phenogamous plants exclusively; Part V will present the ferns and mosses ; while algas and fungi are rele- gated to Part VI. Handbook of Psychology ; Senses and In- tellect. By James Mark Baldwin, Ph. D., Professor in Lake Forest Uni. versity. New York : Henry Holt & Co- 1889. 8vo. Pp. 343. Price, $2.26. In this book the author displays a thor- ough acquaintance with the works of those writers on the subject whose general philo- sophical attitude is different from his own, and he often adopts their conclusions, freely recognizing their merits. The references show a wide acquaintance with psychological works in all languages, and are impartially made, with no discrimination in favor of either Trojan or Tyrian, the author evident- ly intending that the reader shall be made fully acquainted with the literature of the various topics treated. The work is that of a scholar, the style is good, and many special themes are well handled. This is particu- larly true of sensation, though the selection of the word tone to characterize the quality of sensation as pleasurable or painful does not seem to us felicitous. So also the chap- ter on illusions is an excellent presentation in condensed form of a class of very inter- esting mental phenomena. But while the author makes good use of the results of scientific psychological study, his work is vitiated by an inability to get rid of the notion that Psychology must be made a servant of Theology. We are re- minded by his book of Dr. McCosh's works, though Dr. Baldwin is much less anachronis- tic. The difficulty is the old heresy that the human mind has a special and higher faculty for seeing things invisible, by a rational or intuitional apprehension. The moment we apply the term intuition alike to presenta- tive knowledge and to representative prod- ucts— concepts, judgments, inferences — as does Dr. Baldwin, we destroy the funda- mental psychological distinction, and make a jumble of mental science. This is what is always done by those who insist on a " rea- son " and on " rational intuitions." We have yet to see any fairer or better handbooks of psychology than Prof. Bain's and Mr. James Sully's, and either of these we should certainly recommend in preference to the present work, which, spite of excel- lences, is essentially misleading by reason of errors mostly growing out of the above- mentioned confusion. " The New Review." Edited by Archibald Gove. Monthly. London and New York : Longmans, Green & Co. Price, 15 cents a number, $1.75 a year. This addition to the number of monthly reviews deserves to be classed with the best. The first number was that for June, 1889, and the issues that have already appeared have been filled with the contributions of able and well-known writers. Being an English magazine, of course it contains some articles that the American reader would skip as being of rather remote interest ; but much of its contents knows no nationality, for in- stance, " After the Play," by Henry James, and " The Dying Drama," a reply by William LITERARY NOTICES. 271 Archer ; also " The Religion of Self-Respect," by Mrs. Lynn Linton ; " A Month in Russia," by Lady Randolph Churchill ; " Wrestling in Japan," by the Hon. George N. Curzon, M. P. Papers on General Boulanger, the French elections, and the German emperor are among the contents of the early numbers, and the scientific arts are represented by an article on " The Eiffel Tower," by M. Eiffel, and one on " Electric Lighting," by the Duke of Marl- borough. English political problems, general sociological questions, literature, history, and biography are among the fields which " The New Review" has already entered, and Charles Bradlaugh, St. George Mivart, M. Flourens, and Andrew Lang are among the contribu- tors not already mentioned. Its mechanical work is excellent. Handy Lists of Technical Literature. Part I. Useful Arts in General, Prod- ucts and Processes used in Manufact- ure, Technology, and Trades. Com- piled by H. E. Haferkorn and Paul Heise. Milwaukee : National Publishing and Printing Company. Pp. 99. Price with Key, $1.25 paper; $1.50 cloth. As one of the tools of the book trade, this series of lists can not fail to be of value. It furnishes information about a class of books, many of which are published and distributed through other than the well- known trade channels, and hence are not easily found. Part I, already issued, con- tains titles of books in English published since 1880 of the classes specified in its title, entered alphabetically under the au- thor's name, or, if anonymous, under the first word of the title. Each title is numbered, and the names of subjects are inserted in the same list, with cross-references to the titles. References are given also to articles in cyclo- pasdias and to parts of works treating of the various subjects. The size, price, and date of each book are given, and the publisher is indicated by an abbreviation. The key con- sists of a list of the publishers' names for which these abbreviations stand, with ad- dresses, each followed by the list-numbers of the books mentioned which the publisher issues or keeps on sale. An appendix to the " Handy List " consists of a selection of books of the same class published before 1880, and still kept on publishers' and job- bers' lists. Other parts to be published will include lists on military and marine affairs, engineering, mining, fine arts, building, and miscellaneous subjects. A Dictionary of Music and Musicians. Edited by George Grove. Appendix. London and New York : Macmillan & Co. Pp. 306. Price, $2.25. The large demand for this elaborate work, which now appears in a complete form, with its steady increase from the beginning, in Europe and America, are accepted by the publishers as showiug that on the whole the book has fulfilled the intentions with which it started. Shortcomings were to be ex- pected, and may be found ; but with all the allowance that need be made for them, the value of the work is exceedingly great, and is far more than an equivalent return for the cost. Many of the special articles are treatises in themselves, and the biographical notices give very satisfactory accounts of the lives and works of musical men of every class, with fullness proportionate, on the aver- age, to the importance of the subject. The purpose of the appendix, which was prom- ised from the beginning of the publication, is to supply omissions and correct errors in the original text, furnish new information, and bring the whole up to the latest practi- cable dates. It is arranged alphabetically, and forms a considerable volume in itself. A copious index of the whole four volumes will shortly be published in a separate vol- ume. " Bulletin, No. 36," of the United States National Museum, is A Review of the Family Delphinidce, prepared by Frederick W. True, as a contribution to the natural history of the cetaceans. The publication is the forty- seventh of a series of papers intended to illustrate the collections of the National Museum. Previous to preparing the review, Mr. True visited the European museums, in order to examine the type specimens con- tained in them as an essential prelude to the proper comparison of species. He there also met several zoologists, who furnished him information ; among them, Prof. Flower, who placed in his hands the proof-sheets of his own work on " The Delphinidae." The present work differs from Prof. Flower's in that it is directed to the determination of 272 THE POPULAR SCIENCE MONTHLY. species, while the British author makes the discovery of mutual relations and associa- tions into groups a prominent object. The tenth volume of the Resultados del Observatorio National Argeniino at Cordoba, Juan M. Thome, director, contains all the observations made during 1877 for the General Catalogue, the four microscopes, as well as three tallies of transit-threads, having been employed for them ; and the zones from 755 to 759 inclusive, with their reduction- tables, and an index for reference. The number of stellar determinations made dur- ing the year was 17,380, of which 516 were made in zones. Tables of corrigenda for the present volume, and for the errors detected in the volumes already published, are ap- pended. The paper of Mr. Cyrus Thomas, entitled Aids to the Study of the Maya Codices (Gov- ernment Printing-Office), is based on the as- sumption that an attempt to decipher those documents on the supposition that they con- tain true alphabetic characters must end in failure. Some of the characters are more than probably phonetic symbols ; but Landa's alphabet furnishes no help in deciphering them, and is evidently based on a miscon- ception of the Maya graphic system. "If the manuscripts are ever deciphered, it must be by long and laborious comparisons and happy guesses." This paper is intended to be a step in that direction. The author concludes that, at the time the codices ex- amined were written, " Maya culture had reached that stage where the idea of pho- neticism was being introduced into the writ- ing. Yet it is certain, and even susceptible of demonstration, that a large proportion, perhaps the majority, of the characters are symbols. The more I study these characters the stronger becomes the conviction that they have grown out of a pictographic sys- tem similar to that common among the In- dians of North America. The first step in advance appears to have been to indicate, by characters, the gesture-sign." In Hints for Teachers of Physiology (D. C. Heath & Co., " Guides for Science Teach- ing"), Prof. H. P. Bowdilch makes an at- tempt to show how a teacher may supple- ment his text-book instruction by means of simple observations and experiments on living bodies or on organic material, so as to impart to his pupils a knowledge of the foundation on which physiology rests, and bring the impressions made on the senses to aid the memory in retaining the facts com- municated didactically. The essay, though simply a primer, is fruitful in suggestions for familiar illustrations. Though edible mushrooms of many va- rieties are found in all parts of the United States, few of them are utilized, because the majority of the people do not know how to distinguish them from poisonous species. A useful aid to making this very important distinction is furnished in Dr. Thomas Tay- lor's pamphlet of descriptions, with natural- colored illustrations, of Twelve Edible Mush- rooms of the United States ; which also gives directions for selecting and preparing for the table. The paper is embodied in the report of the Department of Agriculture for 1885, and is published separately by Dr. Taylor in Washington. Investigations of sorghum - blight and the mildew of the huckleberry, with certain parasitic insects inhabiting the knots pro- duced by it, and the fungous parasites of weeds, together with experiments in the cross- fertilization of corn and the germination of weed-seeds, are described in the Report of the Botanical Department of the Kansas State Agricultural College Experiment Sta- tion. A number of documents and papers con- cerning the care of the insane, and questions concerning the responsibility of the insane, may be noticed in a group. The Report of the Standing Committee on the Insane of the New York State Board of Charities presents the results of the annual visitation to ex- amine the condition of the eight State hos- pitals and asylums and the eighteen asylums of the exempted counties. The Recent Ju- dicial Departure in Insanity Cases, by Clarfc Bell, reviews two recent decisions of high courts — one of the State of Alabama and the other of the United States — that indi- cate an approach to a more fixed and accu- rate definition of the responsibility of the insane than has heretofore prevailed. — In the case of The Insanity of Oscar Hugo Webber, Dr. J. Hendric Lloyd enters a pro- test against the conviction for murder of a man who in the author's view was insane to irresponsibility. — The question of rcsponsi- LITERARY NOTICES. 273 bility is brought more directly under view in Dr. T. R. Buckharn's paper on the " Right and Wrong " Test in Insanity, in which it is maintained that the subject may be irre- sponsible, if acting under insane impulses, even if he is aware that the deed he is com- mitting is wrong. — Mr. A. Wood Renton, discussing the question of Testamentary Ca- pacity in Mental Disease, collates what the courts have defined as the law on that sub- ject, maintains that the issue on that point should be narrowed, when it arises, to the question, "Was this man capable of making this particular will at the time of its exe- cution? " The Commonwealth is the name of a monthly magazine of 144 pages, published by the Commonwealth Publishing Company, Denver, Col., which in June, 1889, had reached its fourth number. Among several stories and miscellaneous articles, we find two or three relating to the early history of Colorado. Of such are " Glimpses of Early Days," describing the site and sur- roundings of Denver in 1856, before there was a town or house there; a relation of remarkable trials and executions by extem- porized courts that took place in the primi- tive times of " thirty years ago " ; and an account of the attempt to set up a Territory of Jefferson in 1859, while the region of Denver was still technically Arapahoe Coun- ty, Kansas. The effect of a pungent paper, suggesting condemnation of the awkward attitudes into which religious newspapers sometimes place themselves with regard to politics, is neutralized by the editor's depre- ciation of civil-service reform. Dr. T. D. Crothers, in a paper asking Should Inebriates be punished by Death for Crime ? and Dr. Joseph Parrish, in The Le- gal Responsibility of Inebriates, argue against treating inebriate criminals as if they were responsible, and in favor of subjecting them to the same kind of treatment as is given to the insane. Six additional numbers of the Modern Science Essayist, a monthly publication of lectures and essays on topics immediately related to evolution, invite attention. In the first of the group, No. 1, on " The De- scent of Man," Prof. Cope traces the descent in lines not greatly different from those vol. xxxvi. — 18 drawn by Prof. Topinard in a recent num- ber of the " Monthly," and insists that man is still subject to the struggle for existence. In " The Evolution of Mind," Dr. R. G. Ecclcs argues that the elaborate mental functions of man have been gradually developed from the simplest beginnings. In " Evolution of Society," Mr. James A. Skilton treats society as an organism, capable of growth, of de- crease as well as increase ; of vitality, of disease as well as of health ; and of death and decay as well as of life and growth — all by the operation of natural law. In " Evo- lution of Theology," Mr. Z. Sidney Sampson assumes that the tendency of the general movement of the theistic conception is along the same lines as in scientific thought, from narrower to wider generalization ; following the natural order of the evolution of the mind, when free, from lower to higher ideals. In "Evolution of Ethics," Mr. Lewis G. Janes considers the individual as the chief concern, and the individual character as the supreme end, by the perfection of which only society can be perfected. In the. twelfth number of the series, the " Proofs ol Evolution " are summed up by Mr. Nelson C. Parshall as derivable from astronomy, ge- ology, morphology, embryology, metamor- phosis, rudimentary organs, geographical distribution, discovered links, artificial breed- ing, reversion, and mimicry. Alphonse Daudet's La Belle Nivernaise, or the story of a river barge and its crew, has been selected by Prof. James Boielle as the " ideal " reading-book in French for the junior classes of high schools and the higher classes of preparatory schools. Having been written for the author's ten-year-old son, it is commended as a striking example of " a great intellect coming down to the level of a child of tender years, and telling in short, simple, and pithy sentences, preg- nant in meaning, the story of the loving sympathy of the poor for their poorer and more defenseless brethren. The notes give clear definitions of idiomatic expressions, with explanations of etymologies and allu- sions. Ginn & Co. Three numbers — 7, 8, 9 — of the seventh series of the Johns Hopkins University Stud- ies in Historical and Political Science are occupied with a paper on The River Towns 274 THE POPULAR SCIENCE MONTHLY. of Connecticut — Wethersfield, Hartford, and Windsor — by Charles M. Andrews. As in the other monographs of this series, the ori- gin, growth, and development of these towns, with the various phases of social, political, and other life which they have passed through, are reviewed from the historical and philosophical point. The agrarian and civil life of the sturdy people who consti- tuted their population, the author observes near the end of his story, " was not essen- tially different from that existent among the other New England towns ; such life was in its general features everywhere the same. On close examination, however, we find that the machinery of town and court administra- tion can be classified as to whether it is pure or mixed, simple or complicated, natural or artificial. To Connecticut belongs the best of these conditions. Her town life was pure, simple, and natural ; the law which guided her political relations was nearer to the law which governs to-day than anywhere else on the American continent. We are apt to think of her settlement as an artifi- cial importation, as one ready-made through the influence of pre-existent conditions. Be- ginning with the commercial stage, when trade was the motive power, it soon entered the agricultural stage, when the adventure lands were occupied by planters. With the development of this phase of its growth the military stage begins, when it became neces- sary to systematically arm against the In- dians, and to turn the agricultural settle- ments into armed camps, with the people a body of trained soldiers. At this stage the ordinary religious life begins, when system- atic church life arises with the infusion of new settlers ; and last of all is reached the civil or political stage, when for the first time the settlements may be fairly called organized towns." The Batrachia of North America, by Prof. E. J). Cope, is the forty-fifth of the series of papers illustrating the collections of the United States National Museum. The work embraces the results of a study of the character of the species, with their varia- tions, for which the museum furnished lib- eral material, and studies of the osteology of the class, based on the material contained in various museums of the United States and Europe. The manuscript prepared several years ago by Prof. Baird and Dr. Girard has also been used, and ninety-one descriptions of species have been taken from it. The re- sults have been expressed largely in system- atic form, under the belief that descriptive zoology will never be complete until the structure is exhausted in furnishing defini- tions. Reference is made, wherever prac- ticable, to the relations between the extinct and living forms. The general characters of the Batrachia, their general anatomy, larval characters, classification, affinities, and phy- logeny, are considered, and terms and nomen- clature explained, in the chapter introduc- tory to the descriptions. The Annual Report of the State Geolo- gist of New Jersey for 18S8 announces the completion of the magnetic and topographic surveys. The results have already been published and distributed in the first volume of the final report, recently noticed in the " Monthly." The second volume will con- tain full catalogues of the minerals, plants, and vertebrate and invertebrate animals, their occurrence and localities and some practical and economic particulars regard- ing them. The work still to be done in the matter of the geological structure of the rocks of the State consists mainly in combin- ing and systematically arranging the mate- rials which have been collected. A few points remain to be cleared up, and when this is done the volume on structural geol- ogy can be prepared, to be followed by one on economical geology. Among the mate- rial returns that have accrued to the State from the distribution of the reports are the system of artesian well-boring, which was started at the direct suggestion of the sur- vey ; increased attention to the development of the fire and potter's clay properties; drawing attention through the maps to many peculiar advantages of New Jersey ; invest- ments induced by the notices of mines, quar- ries, lime, marls, drained lands, and water supplies ; and benefits to agricultural inter- ests. The present report is brief, and in- cludes " Geological Studies of the Triassic or Red Sandstone and Trap Rocks," with pa- pers on drainage of the Pequcst meadows and the low lands of the Passaic, water sup- ply and artesian wells, and statistics of iron ores, zinc ores, fire clays, stoneware clays, and bricks.

The Name Silnrian in Geology. — We have received from Prof. Dana the follow- ing note in explanation of a change in geo- logical nomenclature recently proposed by him : " The names for the grander divisions of the Palaeozoic series below the Devonian used in most of the recently published works on geology are Cambrian, Lower Silu- rian, and Upper Silurian. Cambrian was proposed by Sedgwick, and Silurian by Murchison, and both names are derived from the names of ancient tribes of Wales. In 1879 Dr. Lapworth proposed to substi- tute the term Ordovician. a term of like origin, for the Lower Silurian, and its adop- tion is under discussion. Although not see- ing any need of further change, I urged, in my paper before the American Geological Society at Toronto, that the name Silurian, if it is to be restricted, should be used for the Lower Silurian rather than the Upper, on the ground that it was more just to Mur- chison and better for the science. I further added that for a new name for the Upper Silurian, rather than go again to Wales for one, we should consider the claims of Bohe- mia, the land where Barrande carried for- ward his great work on the Silurian and associated rocks, or to the region of New York and Canada, made famous geologically by the Palaeozoic labors of Hall, Billings, and others. I stated that the French geolo- gist, De Lapparent, had already used the name Bohemian for the Upper Silurian ; and I then remarked that the lower portion of the Upper Silurian was called the Ontario Division in the Reports of 1842 and 1846 of the New York geologists, Profs. Mather and Emmons, and that this suggested the use of the name Ontarian. This would make the names for the three grand divisions referred to the Cambrian, Silurian, and Ontarian. "James D. Dana." History in High and Preparatory Schools. — Two opposite demands, according to Mrs. Mary Sheldon Barnes, have to be met in teaching history in the high school ; one for the generalities which are the com- monplaces of every scholar, the other for fresh and independent study of historic de- tail from historic sources. As a solution of the difficulty thus raised, the author pro- poses teaching the general truth through the special fact, and making each pupil judge the special fact for itself in its general as- pects. The first step in this direction should be to give the student a little collection of historic data, and extracts from contempo- rary sources, together with a few questions within his power to answer from these ma- terials. " Then let him go by himself, like Agassiz's famous student with the fish, to see what he can see." The prominent char- acteristics of the method employed by Prof. I. B. Burgess, of Newport, R. I., for teach- ing classical history preparatory to college, are, almost exclusive attention to the facts which are essential to the comprehension of Greek and Roman life and its development ; the study of primitive facts, such as maps, pictures of Greek and Roman works ; speeches and writings of Greeks and Ro- mans ; and the use of questions about these facts, which require not the simple repeti- tion of them, but the gathering and compari- son of different fact3, and the drawing of inferences from them by the pupil himself. An Unsettled Part of Minnesota. — The report of the Geological and Natural His- tory Survey of Minnesota for 1887 consists most largely of local details, of interest chiefly to the specialist. The work was pros- ecuted by three parties, two of them operat- ing in the region of the original Huronian and the iron-bearing rocks of northern Michigan and Wisconsin, and the third in the region of Rainy Lake, while briefer surveys were made in other regions. Prof. N. II. Win- chell's examination of the original Huronian leads to some important results which have a direct bearing on the classification of the rocks of Minnesota and of the Northwest. Prof. Alexander Winchcll describes the Hu- ronian region as traversed from east to west by a low, interrupted swell, called the Giant's Range, and by another series of still higher reliefs called the Mesabi Rantje — which must, however, be distinguished from another Me- sabi Range — but without conspicuous feat- ures of mountain relief. As a rule, the sur- face is rugged and uncultivable. Between Fall Lake and Grand Portage, and north of Grand Marais, the region is "a literal wil POPULAR MISCELLANY. 277 derness without inhabitant, without mails, without roads, and with only an occasional party of Indians or explorers, following the ancient and overgrown trails of two centu- ries ago." Fires have denuded the region of its primitive forests ; but the older burn- ings are becoming overgrown with thickets of aspen, white paper birch, cherry, etc. A few remnants of the original forest are oc- casionally found ; and various shrubs and low herbs occur. Many small tracts of deep and productive soil intervene between the almost universal rocky or thinly covered exposures. The summer climate was agree- able, with sunny days as the rule during two seasons. No experience was had of the winter climate. The character of the coun- try covered by Mr. H. V. Winchell's Rainy Lake survey varies greatly in different re- gions. In the vicinity of Rainy and the neighboring lakes, it is very rocky, while west of these lakes the surface consists of drift deposits, and the underlying rock ap- pears only at rapids and waterfalls in the streams and a few places in the midst of the forest. The region within the limits of the glacial lake Agassiz is now covered with a fine growth of timber, both hard and soft wood, and is excellent farming land. Old Cyclopaedias. — The most extensive, and one of the oldest of cyclopaedias is the Chi- nese work, the name of which may be trans- lated as the " Thesaurus of Writings Ancient and Modern," compiled under the scholarly Emperor Kang Hi, which was printed toward the close of the last century. It was the fruit of forty years of labor, and filled 5,020 volumes ; but this by no means implies that it was as large as a European book of that number of volumes would be. Pliny's " Nat- ural History " may be regarded as the oldest European encyclopaedia. The '' Speculum Majus " of Vincent de Beauvais, in the thir- teenth century, was divided into 10,000 chap- ters, several of which were subdivided alpha- betically. About a hundred years later came the " De Proprietatibus Rerum " of the Eng- lish Franciscan Bartholomew de Glanville, which was translated into the English of the day. Johann Alsted's " Encyclopaedia " (1630) was one of the first works that bore the name. The anonymous " Universal Histori- cal Geographical, Chronological, and Classi- cal Dictionary" (1703), a nearly forgotten work, is said to be "full, concise, lively, and, all things considered, wonderfully accurate," but some very funny statements made in it are pointed out. In the next year was pub- lished Dr. Harris's " Lexicon Technicum, or an Universal Dictionary of Arts and Sci- ences," which has been given the credit, that of right belongs to the preceding work, of be- ing the first alphabetical encyclopaedia writ- ten in English. Next to these works fol- low the generation of cyclopaedias which are still known among us, beginning with Eph- raim Chambers's Cyclopaedia (1728) and D'Alembert and Diderot's great work, and coming down to the new edition of the " Britannica," Stephen's " Dictionary of Na- tional Biography," and Appletons' " Ameri- can Cyclopaedia" and their "Cyclopaedia of American Biography." The Ice-Cap of Greenland.— Dr. Frithiof Nansen showed, in the British Association, in opposition to Nordenskiold's opinioD, that the part of Greenland which his expedi- tion had traversed is covered with a shell- shaped mantle of ice and snow, under which mountains, as well as valleys, have quite dis- appeared, and where the configuration of the land and mountains can not be traced. The ice covering rises rather regularly but rapidly from the east coast to a height of nine or ten thousand feet, is rather flat and even in the middle, and falls off again regu- larly toward the west coast. There must be mountains and valleys in the interior of Greenland as well as on the coast. It is al- ready known that there are on the coasts deep fiords and lofty mountains very like those of western Norway, and that they have in some places just the same wild and prominent character. If we entertain the opinion that these fiords were excavated by the ice, we must also conclude that the same ice has been able to excavate valleys and form mountains in the interior of the conti- nent. We have no right, therefore, to seek the reason of the shield-like shape of the ice in the configuration of the land underneath its surface. It must have a shape of its own, which was given, not by the land, but by the meteorological circumstances. No- body could deny that the ice might in some places have an enormous thickness, as it 278 THE POPULAR SCIENCE MONTHLY. filled the valleys and covered up all the mountains. The thickness must be regulated by the quantity of snow falling, and this is largest toward the coast, gradually diminish- ing toward the interior. Hence the thick- ness of the ice would be greatest on both sides toward the coast, just as has been ob- served. The surface of the snow-field in the interior is even and as if polished, resem- bling the undisturbed surface of a frozen sea, the long but not high billows of which, rolling from east to west, are not easily dis- tinguishable to the eye. The principal factor in giving the surface this shape is the wind. A careful observation of a snow and ice cov- ering like that of Greenland is of great im- portance for the theory of the formation of valleys and fiords. It seems that the more we study Greenland, its coasts, and its inland ice, the more convinced we must feel of the power of the ice to perform this work. The Brnce Photographic Telescope. — The Astronomical Observatory of Harvard College has received from Miss C. W. Bruce a gift of fifty thousand dollars for the construc- tion of a photographic telescope such as the di- rector had described in his circular of Novem- ber 28, 1888, as desirable. The instrument will have an objective of about twenty-four inches aperture, and a focal length of about eleven feet. It will differ from other large telescopes in the construction of its object- glass, which will be a compound lens of the form used by photographers and known as the portrait lens. The focal length of such a lens is very small compared with its diame- ter, and much fainter stars can be photo- graphed in consequence. The advantage is even greater in photographing nebulae or other faint surfaces. Moreover, this form of lens will enable each photographic plate to cover an area several times as great as that which is covered by an instrument of the usual form. The time required to pho- tograph the entire sky is reduced in the same proportion. A telescope of the proposed form, having an aperture of eight inches, has been in constant use in Cambridge for the last four years, and is now in Peru pho- tographing the southern stars. It has proved useful for a great variety of researches. Stars have been photographed with it too faint to be visible in the fifteen-inch refract- or of the observatory. Its short focal length enables it to photograph as faint stars as any which can be taken with an excellent photographic telescope having an aperture of thirteen inches. The eight-inch telescope will photograph stars about two magnitudes fainter than can be taken with a similar in- strument having an aperture of four inches. A corresponding advantage is expected from the increase of the aperture to twenty-four inches. Other advantages to be anticipated from the use of such an instrument will arise from the opportunities which the photo- graphs will give for continuous and detailed study. Witb them work can be done at any place and any time, and, by multiplying copies, by any number of observers. And with them more could be added by a single lens to our knowledge of the stars than could be obtained by any number of telescopes of the usual kind. Prof. Pickering is seeking the best possible location at which to mount the instrument. Owing to the difficulty in maintaining regular observations in the East- ern States that arise from the prevalence of cloudiness, he suggests one of the mount- ains of southern California as likely to offer the most favorable climatic conditions at- tainable. What it takes to play a Piece of Music. — Science, says Sir James Paget, will sup- ply the natural man with wonders uncount- ed. The author had once heard Mile. Ja- notha play a presto by Mendelssohn. She played 5,595 notes in four minutes and three seconds. Every one of these notes involved certain movements of a finger, at least two, and many of them involved an additional movement laterally as well as those up and down. They also involved repeated move- ments of the wrists, elbows, and arms, alto- gether probably not less than one move- ment for each note. Therefore there were three distinct movements for each note. As there were twenty-four notes per second, and each of these notes involved three dis- tinct musical movements, that amounted to seventy - two movements in each second. Moreover, each of those notes was deter- mined by the will to a chosen place, with a certain force, at a certain time, and with a certain duration. Therefore there were four distinct qualities in each of the seventy-two POPULAR MISCELLANY. 279 movements in each second. Such were the transmissions outward. And all those were conditional on consciousness of the position of each hand and each finger before it was moved, and, while moving it, of the sound and the force of each touch. Therefore there were three conscious sensations for every note. There were seventy-two transmissions per second, one hundred and forty-four to and fro, and those with constant change of quality. And then, added to that, all the time the memory was remembering each note in its due time and place, and was exer- cised in the comparison of it with others that came before. So that it would be fair to say that there were not less than two hundred transmissions of nerve force to and from the brain outward and inward every second, and during the whole of that time judgment was being exercised as to whether the music was bring played better or worse than before, and the mind was conscious of some of the emotions which the music was intended to inspire. Ancient Chaldean and Modern Measnres. — According to Prof. Harkness, in his presi- dential address to the Philosophical Society of Washington, the ancient Chaldeans used, primarily, the decimal system of notation, and also the duodecimal in the division of the year and of the day into hours, and the sexagesimal in the division of the circle and of the hour and minute. The last two sys- tems were also applied to weights and meas- ures, and impressed upon them by the scien- tific authority of those ancient sages. " Now observe," says the author, " how the scien- tific thought of to - day repeats the scientific thought of four thousand years ago. These old Chaldeans took from the human body what they regarded as a suitable unit of length, and for their unit of mass they adopt- ed a cube of water bearing simple relations to their unit of length. Four thousand years later, when these simple relations had been forgotten and impaired, some of the most eminent scientists of the last century again undertook the task of constructing a system of weights and measures. With them the duodecimal and sexagesimal systems were Out of favor, while the decimal system was highly fashionable, and for that reason they subdivided their units decimally ; but they reverted to the old Chaldean device for ob- taining simple relations between their units of length and mass, and to that fact alone the French metric system owes its survival. Every one now knows that the metre is not the ten-millionth part of a quadrant of the earth's meridian, and in mathematical phys- ics, where the numbers are so complicated that they can only be dealt with by the aid of logarithms, and the constant it, an utterly irrational quantity, crops up in almost every integral, mere decimal subdivision of the units counts for very little. But in some depart- ments of science, as, for example, chemistry, a simple relation between the unit of length (which determines volume), the unit of mass, and the unit of specific gravity, is of prime importance ; and wherever that is the case the metric system will be used. To engineers such relations are of small moment, and, con- sequently, among English - speaking engi- neers, the metric system is making no prog- ress, while, on the other hand, the chemists have eagerly adopted it. As the English yard and pound are the direct descendants of the Chaldean-Babylonian natural cubit and mina, it is not surprising that the yard should be only 0*48 of an inch shorter than the double cubit, and the avoirdupois pound only 665 grains lighter than the Babylonian commercial mina; but, considering the ori- gin of the metric system, it is rather curious that the metre is only 1"97 inches shorter than the Chaldean double royal cubit, and the kilogramme only 102 grains heavier than the Babylonian royal mina. Thus, without much exaggeration, we may regard the pres- ent English and French fundamental units of length and mass as representing respect- ively the commercial and royal units of length and mass of the Chaldeans of four thousand years ago." Monnt Roraima. — Mount Roraima, that sharply perpendicular elevation in Guiana which so long defied attempts to reach its summit, has been ascended twice since it was first conquered by Mr. Im Thurn in 1884 — by Mr. F. Dressel and Mr. Cromer, in Oc- tober and November, 1886. While Mr. Im Thurn's ascent took place at the beginning of the rainy season, Mr. Dressel's was in the dry season, and their respective observations were marked by corresponding differences. 280 THE POPULAR SCIENCE MONTHLY. Mr. Im Thurn had observed no animal life while he was upon the mountain ; Mr. Dies- sel saw a few butterflies, all of a dark-brown and nearly black color. In the shallow ba- sins a few specimens of a small black toad with a yellow spot on the throat were found. A third animal form was noticed in the moist earth attached to some plants which had been pulled up — a milliped. The fan- tastic shapes into which the sandstones have been formed, and the calmness of the scene, affected Mr. Dressel as they had Mr. Im Thurn. Experience and Training in Mechanical Work. — To be a good mechanic, said Sir Benjamin Browne, at the recent meeting of the British Association, long training is neces- sary; and, above all, ability to distinguish good work from inferior work. A regular course of progress from one branch to an- other should be carefully followed, so as to teach every class of work up to the most dif- ficult. In this the real interest of the em- ployer is the same as that of the lad, viz., to learn every step thoroughly, and then pass on to something more difficult. The author contended that a long training in a manu- factory is absolutely necessary, and this should be supplemented by theoretical and technical instruction. It would probably be a great gain to give a lad six or eight months of theoretical teaching after he is out of his apprenticeship. The old-fashioned system of apprenticeship, not much short- ened, and with very slight modifications, is the only reliable method for cither employer or mechanic to learn his business ; but, as work has become more scientific and elabo- rate, it is necessary for any young man who wishes to excel to have a good theoretical and technical training in addition to his fac- tory experience. How Stone Implements were made. — Mr. Gerard Fowke, of Sidney, Ohio, has been studying the manner in which primitive man made his stone implements. Although the subject is one on which absolute knowledge can never be obtained, he has been able to reach some definite conclusions on it. Some of the material was obtained from extensive quarries in Coshocton County, and between Newark and Zanesville, Ohio, where the hills are seamed for miles with the trenches and pits left by the ancient diggers. To get the flint, the overlying stratum of earth, nine or ten feet thick, had to be removed, with wooden tools. The rock was then cracked by building a fire, and probably pouring water upon it, the process being repeated till the limestone was reached and a hole made large enough to work in. Other cracks were made by building a fire at the lower part of the ledge, and the split rock was de- tached. This work was sometimes carried on for several hundred yards. The stones were reduced to blocks of suitable size by stone hammers weighing, perhaps, two hun- dred pounds, and the shaping was carried on with hammers running, according to its stage and the quality of work desired, down to two ounces in weight. The finished object was smoothed and sharpened by rubbing it with sandstones. If a hole was wanted, it was drilled with a stick, cane-stem, piece of bone or horn, flint, or piece of sandstone, which was revolved in the hands, or twisted back and forth with the bowstring. This was not a speedy process. Dr. Bau worked at it experimentally for two years, and left his first hole not bored through. Yet some of the Amazon tribes spend the lifetimes of two men in drilling, with the flexible shoot of a wild plantain and sand and water, the bores of their tubes of rock crystal. Handles were fitted on in a rude way and secured by wrapping with sinew, which shrunk and bound them tightly ; or, with the aid of gum. The fashioning of arrow- heads was a very delicate and curious work, requiring skillful manipulation, and was performed with stone hammers or chisel-points of deer-horn or wood. Bellito. — The new explosive, bellite, was recently subjected in England to some very satisfactory tests of its safety and power. Letting a great weight fall upon cartridges composed of it, they were simply crushed into a hard mass. But when the crushed car- tridges were afterward detonated by means of a fulminate, immense energy was developed. Again, when placed in the fire of a smith's forge, it was volatilized. The effect of ex- ploding a three-ounce cartridge on the lid of a case containing bellite was simply to pulverize the wooden case and scatter the POPULAR MISCELLANY. 281 contents. Comparative experiments showed that, when bellite was confined, the energy developed on detonation was equal to that of dynamite ; but that when unconfined, bellite apparently did less work. In mine- blasting bellite was proved capable of doing the work of three or four times its weight of gunpowder, without the fumes that rise when dynamite or gunpowder is used. Distribation of Rotifera. — Of the little animals classified as Rotifera, the most spe- cies have been found in Great Britain — not certainly because they are more abundant or varied in England than elsewhere, but be- cause they have been more industriously looked for, and more found there. In late years, two and a half times as many species have been added to the British lists as to those of all other countries put together. There are curiosities in the distribution of these animals. Twenty-four out of the re- corded species in Australia are also British ; and of the remaining species, one has a habitat in the United States. The same phenomena occur, though on a reduced scale, in the United States, Jamaica, and Ceylon. The question arises, How could these minute creatures, which are inhabitants of lakes, ponds, ditches, and sea-shore pools, contrive to spread themselves over the whole earth ? A species which is known only in a small duck-pond in England has also been found at Sydney. Another species has been found almost simultaneously at Sydney and in On- tario. These creatures, " to whom a yard of sea-water is as impassable a barrier as a thousand miles of ocean," could only have reached distant countries in the egg; this they do by the hardy ephippial egg. These eggs fall to the bottom of the water in shal- low pools, or are attached to the confervoid growth on the stones. The pool dries up, is swept by the winds, and the eggs are lifted up and carried away. There is hardly any limit to the distances to which they may be thus taken and yet keep vital. Then, as Dr. C. T. Hudson shows in his paper on this sub- ject, " the eggs, of course, must often fall on unsuitable places, and be carried past suitable ones, and this accounts for the capricious appearance of Rotifera in some well-watched ponds, and for the frequent disappointment of the naturalists who visit such spots. To this aerial carriage of the eggs is also due the perplexing fact that when any rare Rotifera is found in one spot, it is frequently found at the same time in closely neighboring ponds and ditches, even in such an unlikely hole as the print of a cow's foot filled with rain, but not at all in more promising place, at some distance off." They may also be distributed by water-birds and dogs. The animals themselves are very hardy against heat and dryness. The Phila- dinadce, when time is given them to don their protective coats, oan bear a heat gradu- ally advancing to 200° Fahr., or a fifty days' exposure to a dryness produced over sul- phuric acid in the receiver of an air-pump. The City of the Cat-Goddess.— M. Edou- ard Naville recently gave before the Victoria Institute an account of his important dis- coveries at Bubastis, one of the ancient great cities of the Delta of Egypt, and the princi- pal seat of the worship of the cat-goddess, Pasht. The speaker said, at the beginning of his lecture, that it was remarkable that while one of the latest writers on the East had referred to the failure of the prophecies of Ezekiel regarding the cities of Egypt, he had himself found in the same prophecies the light by which he was guided in his search. Bubastis was found to have been a city of much more historical importance than had generally been supposed, the recovered monuments bearing dates all the way down from the fourth (or Pyramid - builders') to the thirtieth, or last Egyptian, dynasty. The most conspicuous relics were of the fourth, sixth, twelfth, shepherds', nineteenth, and twenty-second dynasties. Some very inter- esting relics of the shepherd-kings, hitherto rare except at Tanis, were found ; and from the beauty of their statues, and other evi- dences, the author concludes that they must have been a highly cultivated people, and have come probably from Mesopotamia. Dr. Virchow considered that their monuments represented Turanians, and Prof. Flower that they represented people of a Turanian or Mongolian type. But that did not mean that the population itself was Turanian. Their worship and language were of a She- mitic type, but the statues of their kings showed that they were not Shemites. M. Naville remarked : " It was then what it still 282 THE POPULAR SCIENCE MONTHLY. is now ; and I believe that the conquest of Egypt by the Hyksos is not unlike what would happen at the present day if the population of Mesopotamia overran the val- ley of the Nile : you would have masses, in great majority of Shemitic race, speaking a Shemitic language, and having a Shemitic religion, but under the command of Turks, who are not Shemites, but Turanians." M. Naville regards the successive discoveries that have been made in the Delta as making the Bible-story more comprehensible in some points, and as showing that the distances were much shorter than was generally thought. "I consider it important, for instance, to have established that Bubastis was a very large city, and a favorite resort of the king and his family. It is quite possible that, at the time when the events preceding the Ex- odus took place, the king was at Bubastis, and not at Tanis, as has been generally be- lieved." Composition of London Fogs. — Studies of London fogs by various observers show that during the winter the air of the metropolis has an unusually large amount of carbonic acid in it. Thus, Dr. W. J. Russell found on one day, a few years ago, that it contained more than three and a half times the average amount. This is derived, to a large extent, from respiration, and more from coal-burn- ing ; and " it is almost indisputable that the latter produces the well-known black fogs and yellow fogs." The relative thickness and density of the air of different parts of London have been investigated by Mr. W. H. Raffles, who took a station on Primrose Hill and ob- served the visibility, on different days, of prominent objects at known distances in dif- ferent directions. These observations showed plainly that the amount of fog was largely governed by the density of the population and the frequency of factories. A similar conclusion is drawn from the number of hours in the daytime on which artificial light was used. Ilomerton had twice as many hours of darkness as any other district rep- resented in the tables, and it has a very large number of factories in its neighbor- hood. Of other towns in which the inquiry was pursued, Leeds suffered most from dark- ness, probably for the same reason ; while Manchester is said to have been unusually free of late years from dark fogs, probably because many mills have moved out. The ordinary white fog has also been reduced by the draining of morass lands near the city. A conception of the cost of London fogs may be gaiued from the fact that during nine days of fog in November, 18S7, the public paid a single one of the several com- panies four hundred and ninety pounds, or twenty-four hundred and fifty dollars, an hour for artificial light. Geological History of Yellowstone Park. — The geological history of Yellowstone Na- tional Park has been traced by Mr. Arnold Hague in an address before the American Institute of Mining Engineers. Throughout Tertiary time the history was characterized by great volcanic activity. Within very recent times there is no evidence of any consider- able outburst; indeed, the region may be considered long since extinct. The volcanic rocks present a wide range in chemical and mineral composition and physical structure, but may all be classed in the groups, follow- ing one another in the order named — ande- sites, rhyolites, and basalts. Since the close of the Ice period no geological events of any moment have brought about any changes in the physical history of the region other than those produced by the direct action of steam and thermal waters. Indications of fresh lava-flows within historical times are wholly wanting. All our observations point in one direction, and lead to the theory that the cause of the high temperature of the waters of the geysers and hot springs must be found in the rocks below, and that the ori- gin of the heat is in some way associated with the source of volcanic agency. But it does not follow that the waters themselves are derived from any deep-seated source; on the contrary, investigation tends to show that the waters brought up by the springs are mainly surface-waters which have percolated downward a sufficient distance to be heated by large volumes of steam ascending through fissures and vents from much greater depths. The existence of such currents of steam and hot water is attested by the decompositions they have effected upon the rocks, which " have proceeded on a most gigantic scale"; and they have left an indelible impression upon the surface of the country. The study POPULAR MISCELLANY. 283 of the age of the present geysers by observa- tion of the rate of deposit of sinter indicates a great antiquity for them — over twenty-five thousand years for " Old Faithful." Our accurate knowledge of them only began in 1871. The number of geysers, hot springs, mud-pots, and paint-pots scattered over the park exceeds thirty-five hundred, and the addition of the fumaroles and solfataras would make the whole number of actual vents double that. Mound-Bnilders and Indians. — "Some Popular Errors in regard to Mound-Builders and Indians" are reviewed by Mr. Gerard Fowke, in the " Ohio Archaeological and His- torical Quarterly." The high civilization ascribed to the mound-builders is denied, because they have left no evidence that they could use stone-dressing tools, could carry earth only in baskets or skins, and have left no indications of having possessed a written language or domestic animals, etc. Against the assumption that they possessed a great population, it is shown that while the construction of all their works in Ohio did not require an amount of labor equal to that used in the excavation of certain mod- ern works, there is nothing in the way of their having had an indefinite time in which to perform it. While " there is sufficient accuracy in some cases to make one wonder that the builders could have done as well as they did, no evidence appears of any 'cal- culation' beyond the mere sighting and measuring possible to any one." The sup- posed evidences of the great antiquity of the mounds and of the extensive commerce of the builders are assumed to be insuffi- cient or fallacious ; minor errors, concern- ing the distance from which the earth used in building the mounds had to be brought, concerning the size of the builders, the soundness and other peculiarities of their teeth, and the supposed artistic excellence of their work, are corrected ; and the questions whether there is anything in their work that the Indians could not have executed, and whether the Indians had knowledge of them, are taken up. Traditions exist among the Indians of Michigan and Wisconsin of tribes who built mounds, and of definite occasions when mounds were built. A certain tribe were called by the Sioux Ground-House In- dians, because they lived in houses covered with earth. The chronicles of De Soto's ex- pedition describe the houses of the Cherokees as being built upon mounds, and the French give a similar description of the house of the king of the Natchez. Certain earthworks in western New York, Ohio, and Pennsylvania are conceded to have been built by the Iro- quois and adjacent tribes. The Indians of the Ohio Valley may have been ignorant of the subject, because they were a comparatively recent arrival. It is objected that the In- dians could not have built the mounds, be- cause the builders must have been a settled and agricultural people, while the Indians live by hunting and fishing. But it is a his- torical fact that, before they were disturbed by the whites, the Indians also were agricult- urists, raised good crops, and stored their grain, so that they were able to supply the expeditions that came among them. We can not judge of what they were from what they are, after having been ruined by their contests with the whites and their vices. The race that produced a Logan, a Corn Planter, a Red Jacket, a Tecumseh, and other men of like genius, might also have developed men competent to construct all the works that now puzzle us. Some of Mr. Fowke's assertions are traversed and shown to be erroneous in the " American Antiqua- rian," which, while it admits that the Indians built mounds, holds that there were other and more extensive mound-builders before them. Experiments in Germination. — A series of testings of the influences of certain condi- tions on the sprouting of seeds, described in a bulletin of the experiment station at Cor- nell University, indicates that variations of temperature are an important factor in the matter, and that a constant temperature gives quicker results than an ordinarily vari- able one of which that is the mean. The mean employed in most of the experiments was 74° ; but there is probably a tolerably well-defined best temperature for each spe- cies of plant, the limit of which is not close- ly determined for most garden seeds. Soak- ing the seeds does not appear to influence the total amount of sprouting ; nor does it seem to hasten the sprouting, if the planting- time is reckoned from the moment of putting 284 THE POPULAR SCIENCE MONTHLY. the seeds to soak ; it only shortens the time the seeds have afterward to remain in the soil. The character of the soil may influ- ence the results. Light, when it has any in- fluence— and it has great influence with some species — has a retarding effect. The weight of the seed is often a tolerably accurate measure of its viability. As a rule, heavy seeds germinate better than light ones of the same sample. When variability was perceived with reference to color, the stronger sproutings usually occurred in the darker-colored seeds. The latitude in which seeds are grown may determine their behav- ior in germination — northern-grown seeds seeming to germinate more quickly than southern-grown. More than one test is need- ed to be decisive respecting any sample of seeds. There appear, from the testings re- ported, to be no pernicious adulteration of garden seeds in this country, and no hurtful impurities. Tapioea. — The manihot, or tapioca plant, was originally a native of tropical South America, but is now largely cultivated throughout all tropical countries. It is a small, shrubby plant, growing from four to eight feet high ; and becomes suitable for use in from sixteen to eighteen months after the young plants are established. Besides the well-known wholesome food, the root abounds in a peculiar poisonous juice, which is said to be analogous to hydrocyanic acid ; but this substance being volatile and easily destroyed by fermentation, no difficulty is met in procuring the food-product free from it. The pulp obtained from the roots is washed in cold water, after which, upon resting, the starch subsides. The water is then drawn off and the starch is heated, when pearl tapioca is obtained. In prepar- ing the cassava meal, the roots having been prepared, are baked on an iron plate. Thus prepared, the meal swells considerably in water or broth, and is called ccrraque. K, instead of drying the grated pulp, it is spread upon a hot iron plate, the starch and mucilage, by mixing together, consolidate the pulp and form a biscuit, called cassava bread, which is a very important and nutri- tious food. The resultant of the mastication of these cukes, upon fermentation, produces an agreeable but intoxicating drink. The Island of Paros and its Marbles. — The Island of Paros, according to Mr. R. Swan's description in the British Associa- tion, is eleven miles long and eight miles broad at its widest part, with a mountainous interior rising to a height of twenty-five hundred and thirty feet, and a broad belt of nearly level land round the coast. The southern part of the island consists chiefly of crystalline limestone, of undefined age but probably Cretaceous. The finest statu- ary marble, or lychnitis, varies from five to fifteen feet in thickness at the quarries of St. Minas, and occurs in a bed of coarse- grained white marble with bluish -black veins. The coarse marble becomes dark in color near the lychnitis, both above and be- low it, and thus the layer of statuary marble is distinctly marked off. The dark color is due to traces of binoxide of manganese and ma XI o lit or 3 H ? *~l UJ THE FUTURE OF OUR COTTON MANUFACTURE. 313 In the chart which I have referred to, I have compared the relative humidity of the atmosphere at New London, Conn., with that of Augusta, Ga., from General Greely's ta- bles, and I have added the data of New Bedford, Mass., from the private records which have been kept for a very long pe- riod by Mr. T. R. Rodman and his father. I have also com- piled some data relating to Atlanta, Ga. The general results derived from these two charts prove that the mean temperature of Atlanta is 12f° Fahr. above that of New London, with 13£ less per cent of relative hu- midity, and subject to a vastly greater variation day by day. Augusta, perhaps the principal center of the cotton manufact- ure of the South, yields a lit- tle different result : the mean temperature of New London through the year is 49f ° ; at Augusta, Ga., 64"4°, a differ- ence of a little over 15° in heat. The mean relative humidity at New London is 74'53 per cent ; the greatest variation in the year, 23*4 per cent; the mean variation, 10 per cent. At Au- gusta, Ga., however, the mean relative humidity is 71'42 ; the extreme variation 55 per cent, and the mean variation 37'45 per cent in relative humidity, or nearly four times as much as at New London.* * Since this paper was written, through the action of the New Bedford Board of Trade, Mr. R. C. P. Coggeshall has been vol. xxxvi. — 20 3 h THE POPULAR SCIENCE MONTHLY. Now, I think no one would care to attempt fine spinning nnder a hot sun where the humidity of the outer atmosphere changed between seven o'clock in the morning and three o'clock in the afternoon from 84 per cent of moisture to 38, or from 93 to 50. Bear in mind that the variation charted, as I have presented it, is the mean variation of each and every day, averaged by months. It will be observed that this change in the humidity of the air makes the heat more comfortable and more easy to bear ; that is the reason why our Southern friends complain of the heat of the summer as compared with their own when they come North ; but, whether these conditions and variations are conducive to spinning and weaving cotton, my hearers are better judges than I am. It may be remembered that we took this subject up some years ago, but I do not think it was then ripe. It might be judicious for the association to make some arrangement for a very thor- ough and complete study of this matter, in connection with a very visionary proposition which I am about to submit, for making use of freezing apparatus in tempering and controlling the air of factories. I was unable to take this subject into consideration until very lately, and I need to apologize for the superficial treat- ment which I have given it. I introduce it because I think it may be a most important and perhaps the paramount factor in de- termining— 1. Where the coarse work, 13 to 20, may be done. 2.

The results are as follow : Mean temperature, dry bulb 48'9° F. Wet bulb 46 -4° F. Mean relative humidity, 7 a. m 90 per cent. Mean relative humidity, 2 p. m *74 " Mean relative humidity, 9 p. m 90 " Mean of the year 84 " Maximum during the year 100 " Minimum during the year 60 " I have also received readings for the mean relative humidity of Prestwich, a suburb of Manchester, in Lancashire, but not situated high above the sea on the crest, like the Old- ham district, Prestwich being only 294 feet above the sea-level. The readings for 9 a. m. show a mean relative humidity of 84 per cent ; for 9 p. m., 87-6 per cent. There is no mid- day observation. The variations morning and night correspond very closely with those of New Bedford, the relative humidity being a little lower. I am led to believe, from all that I can learn, that so far as atmospheric conditions constitute a factor in cotton-spinning, the conditions of the southern coast of New England, where the climate is affected by the moisture from the Gulf Stream, are as favorable as those of Lancashire to any kind of work. THE FUTURE OF OUR COTTON MANUFACTURE. 315 3. Where the medium, fine work, 40 to 80, ought to go. 4. Where the finest, 80 to 200, or upward, must go, unless we can prepare a special atmosphere for each class of work. I looked over a few numbers of the reports of the Royal Meteorological Society of Great Britain, and, while I find there are great variations in the relative humidity of the atmosphere in different parts of Great Britain, the changes are not as great as they are in this country, even between morning and night. I can not find any midday record as yet. I have sent for one. Neither have I been able to find a record of a manufacturing town, but I should infer that the conditions of Buxton, one of the stations, might correspond to Oldham, Preston, etc. Buxton is, as you know, an inland health-resort on the peaks of Derbyshire, not far from Manchester, about a thousand feet above the sea- level, not much higher than Oldham, and facing the Gulf Stream. The mean temperature of the year at 9 a. m. is 44*15° ; 9 p. m., 42*5° ; extreme temperature, 1888, 79"2° ; mean relative humidity at 9 a. M., 90 per cent ; 9 p. M., 92 per cent ; highest point, 95 per cent; lowest, 80 per cent; variation, 15 per cent. No wonder it rains easily where the atmosphere is within less than 10 per cent of the saturation point almost all the time. Since dictating the foregoing statement, Mr. Clayton, of the Blue Hill Observatory, has kindly computed the mean relative humidity of the atmosphere at Greenwich, England, from data within his possession, for the years 1884, 1885, and 1886. The mean of the hours 7 a. m. and 3 P. m. is 87 per cent ; the extreme variation, from 95 per cent of humidity at 7 a. m., October, 1886, to 49 at 3 p. m., August, 1884. As I have before stated, the changes at Greenwich are very much greater than they are in Lancashire. I hope to procure figures for Lancashire, which I have sent for, before this report is published. I have thus given some of the apparent advantages of New England over the South. I will now present some of the advan- tages of the Piedmont plateau, of the foot-hills, and of the upland country of the South, for the manufacture of coarse fabrics, even though the extreme of heat in the summer months is less condu- cive to continuous work throughout the year than the extreme of cold of our winter climate, and even though the humidity, both absolute and relative, of that section of our country is very much more variable than upon the south shore of New England. While pointing out the advantage upon coarse numbers, I also call your attention to the indications that the demand of this country for coarse and unbleached fabrics is relatively diminish- ing while the consumption of the finer bleached and printed fabrics is relatively increasing. As soon as people can afford to wear a " b'iled " shirt rather than a gray cotton, or a fancy satine 316 THE POPULAR SCIENCE MONTHLY. rather than a common print, they will have them and they can now well afford to pay for them. I was under the impression until I took up this subject that the North had a positive advantage in pure water for bleaching and finishing, for the reason that all the rivers south of the lower margin of the glacial drift, which ended at the mouth of the Del- aware River, are muddy or turbid during a large part of the year, and there are no ponds or lakes of clear water; hardly any of any kind in the cotton States. My correspondence with Mr. John Hill has disposed of this superficial doubt by calling my atten- tion to the facility with which very pure and very soft water may be derived either from abundant springs or from artesian wells. There is no point to be made against the South on bleaching and coloring. Again, so long as the supply of native operatives suffices, there may be a great field hardly yet occupied, in the production of coarse rather than of fine cotton fabrics, without trenching or taking away from us any part of the work which we can do in the best way. I think our Southern friends may develop a very important branch of textile industry in spinning and weav- ing below No. 20. It will be observed that this whole problem turns upon an aver- age advantage claimed by the South over the North of about one cent a pound in the price of cotton. This present advantage, whatever it may be, will be reduced whenever the volume of Southern railway traffic becomes greater and freight charges are cut down ; but it may always be a considerable point on heavy goods. There is not, however, the full difference of the freight between the North and the South. Very few mills can supply themselves with cotton, even in the South, from the immediate neighborhood ; and, when cotton must be baled and put upon cars for transportation, the local rates are apt to be quite heavy for short distances. The advantages claimed by the South on account of the longer hours of work can not be admitted. In the first place, they will soon be shortened, either from choice or necessity ; and, in the second place, I doubt if any very skillful manager now thinks that high speed can be profitably maintained more than ten hours a day. Again, it is claimed that wages are lower in the South than in New England. This is true. The rate of wages is lower, but I doubt if the cost of labor is any lower, if as low. It may be in a very few of the best managed mills, but in taking the census of 1880 I made a very careful computation of the proportion of hands to spindles and looms, and after making every allowance for dif- ference in yarn, in number, and in quality of mills, I found that THE FUTURE OF OUR COTTON MANUFACTURE. 3i7 there were substantially two hands employed in the South against one in New England, and this computation has been sustained by my observation in such mills as I have visited. Now, it is well known that the more hands the more waste, the more want of discipline, the more lack of good work. In a recent report on Russian spinning by our friend Mr. Dobson, who spoke to us on carding-engines, he reaches identically the same con- clusion in comparing Russia with Great Britain. Doubtless there has been great improvement in Southern methods since 1880; with increased efficiency, the number of hands decreases ; but the wages or earnings rise, and will continue to do so, until they become equal to what we pay. I am, therefore, confident that we may hold a long lead, and that we need not yet borrow trouble from any competition in Southern factories after they have learned to keep their deprecia- tion account, and after they cease to run the risk of bankruptcy by working their machinery into their fabrics without charging it off. I might here rest my case ; but I will venture to give a few more facts bearing upon this subject. There is one development of science which may render the cot- ton-factory entirely independent of climatic conditions. One of the visionary theories which I presented many years ago has not yet been put into practice in any great measure. I sug- gested preparing the atmosphere which is to be used as an in- strument for taking away the moisture from the slashers by carrying it into the sizing-room through a chamber filled with ice. Since that date there has been immense progress in the art of freezing. Frozen carcasses of mutton are now carried from Australia to England. When the trade was first established, the owners of the Victoria Docks in London prepared chambers which were cooled by ammonia machines sufficient to hold 3,200 car- casses. There were four chambers of 12,000 cubic feet each, sup- plied by a ten horse-power engine, delivering 10,000 cubic feet of air below the freezing-point per hour. There are now on the Royal Victoria Docks sixty chambers of 240,000 cubic feet ca- pacity, supplied with 370,000 cubic feet of air below the freezing- point each hour, by a three hundred and twenty horse-power engine. These chambers will hold 80,000 carcasses of mutton at one time. I lately put a very commonplace question to the F. W. Wolf Company, of Chicago, manufacturers of freezing machinery. I asked them, as if it were an every-day ordinary matter of busi- ness, at what price they would put down an ammonia plant suit- able for maintaining the temperature of a cotton-mill three hun- dred feet long, one hundred feet wide, twelve-foot post, four stories 3i8 THE POPULAR SCIENCE MONTHLY. high, at a uniform degree of 70° Fahr. throughout the summer. To which they replied : " Yours of the 9th instant is at hand. We can furnish you one of our No. 5 Linde refrigerating machines, having a capacity equal to the melting of twenty-five tons of ice in twenty-four hours" (this is the standard of the effectiveness of this ma- chinery). " With this machine the temperature of a spinning-mill of the size given may easily be kept at 70° Fahr. We will furnish the whole plant, including the necessary cold-air pipes, ventilators, etc., for the sum of fifteen thousand dollars." I have written to them to know what would be the cost of operating this machine. Cotton manufacturers may yet be obliged to convert their mills into sanitariums, to which they may attract, not perhaps the most attractive women of the land, but those most capable of be- ing attracted by attractive conditions of work, by offering them the most equable and pleasant temperature, most conducive to health, which they can find in any occupation open to them. This will only be in the line of all the other improvements which have been made in mill operation. All progress consists in alleviating the noxious and arduous conditions of labor, in enabling the workmen to increase the prod- uct with lessening effort, in shortening the hours of labor, in rais- ing the rate of wages, and in reducing the cost of production. In this line of progress there is room and to spare for us all. We of the North may retain what we possess and we may continue to gain in the finer branches of the textile arts. At the same time we may welcome our Southern friends in their effort to supply themselves and to share the wider markets of the world, which may soon be open to us by the removal of the duties on the crude or partly manufactured materials which are necessary in the con- struction of our factories and in the processes of our industry. I am conscious that I have covered too much ground. My time does not suffice for condensing what I have to say. I have given my manufacturing friends an optimistic view of the future of cotton-spinning in this country. Bear in mind that for any im- mediate application these figures are all rubbish. There is at the moment an overstock of Southern goods, and apparently an over- supply of heavy goods and of colored goods in the North as well. Therefore, unless they act upon old Billy Gray's principle of mov- ing against the evidence, and operating always when appearances are most adverse, they will conclude that, although we may re- quire five million spindles in the next ten years, the man who puts in a foundation next year may make a great blunder. I have ventured to suggest to the promoters of the Exhibition PUBLIC SCHOOLS AND CRIME. 319 of 1892 that a considerable part of that undertaking shall be de- voted to object-lessons in the development of the arts of life, tak- ing as my example spinning and weaving. The distaff, used as it was in the days of Homer, may still be found in use in northern Italy. The hand loom and the spinning-wheel of prehistoric type are presented in these pictures from China. Other methods of spinning, and other wholly different forms of hand loom car- ried in the hand for weaving narrow stripes, may be brought from central Africa, and so the whole history of the textile arts may be gathered in one place, either by obtaining examples from different parts of the world, or any one may study the whole development of the cotton manufacture if, before it is too late, he will visit the heart of the eastern Kentucky mountains, and from there journey by way of the neighborhood mills of the South to the great fac- tories of the North. PUBLIC SCHOOLS AS AFFECTING CRIME AND VICE. By BENJAMIN EEECE. THE political and material progress of the nineteenth century have been truly wonderful. The past year was memorable as the anniversary of the inauguration of the first President of this great republic, and what a record of bewildering changes do those hundred years unfold ! Thirteen States have been increased to forty-two, and the center of population has moved back from the seaboard to a point nearly a thousand miles in the interior. The lakes of the North have given birth to gigantic commercial marts, which rival in trade, wealth, and culture those seats of an- cient pomp, and empires and cities of mediaeval grandeur, which flourished on the shores of the Mediterranean. The affairs of the remotest portions of this immense domain, together with the world's more notable events, are regularly re- corded in the daily press and read the morning following at the breakfast table. The traveler boards the train at New York, having telegraphed his friend in Chicago to meet him at the station twenty-four hours later, giving the exact minute of his arrival at a place a thousand miles distant from his starting- point. A change of cars is made for San Francisco, and after riding over hundreds of miles of fertile prairie covered with growing crops, crossing wide rivers spanned by bridges which fifty years ago were deemed impossible, across boundless plains where countless herds of cattle and flocks of sheep are fed, and passing through vast mountain ranges pierced by tunneled pas- sage-ways, the traveler reaches his destination upon the shores of 32o THE POPULAR SCIENCE MONTHLY. the Pacific Ocean the very minute of the day announced to him by the ticket agent in New York. If we turn our thoughts seaward the development is no less remarkable ; for the long, dangerous, and uncertain voyages once made by sail to Europe are now conducted with almost equal regularity and safety, and the mammoth steamers of the Clyde accomplish in days the trips which formerly took months to per- form, and, within an hour of the safe landing of the passengers, the electric telegraph through the media of lines and ocean cables discloses to friends at home the news of their safe arrival. In the political world the progress of the century has not been less marked. England, which during the reign of George III so per- sisted in tyrannical measures of taxation as to push its American colonies into a successful struggle for freedom, has extended the utmost liberty of action to its remaining American dependencies and Australian colonies ; so, when Britain was threatened with hostilities in the East, she moved to the scene of action the dusky warriors of her Indian empire, while the impetuous youth of her distant colonies volunteered to do her service on the desert sands of Africa or in the mountain fastnesses of Asiatic Russia. "Within a generation has been witnessed the voluntary liberation of the serfs of Russia, the slaves of Cuba and South America, and in our own country chattel slavery was forever extinguished by the sword. The growth of liberal ideas and the love of liberty have been very marked. Hungary has been granted the right to legislate upon its own affairs ; a republic has been established in France, and in spite of dire forebodings and prophecies of evil it has with- stood every shock and weathered every storm ; while the greatest of English parliamentary leaders, in his declining years exhibit- ing all the ardor of youth, combined with the vigor of robust manhood and the matured wisdom of old age, has brought his fellow countrymen to a recognition of Ireland's wrongs, and is moving the English masses to extend the principles of Anglo- Saxon liberty and home rule to Ireland, which for centuries has been inthralled. But volumes would be required for the mere enumeration of the growth and development which have come with extended knowledge and the more general schooling of the people. Is it any wonder that statesmen unstintingly provide for the wants of our public schools ; that divines dwell with rapture upon the blessings they have brought us ; that political orators eulogize them as the foundation of our prosperity and the main- stays of our liberties ; that agitators vehemently demand an ex- tension of their benefits ; or that the people feel an honest and unquestioning pride in this governmental institution of their own creation, which has promoted religious tolerance, extended the PUBLIC SCHOOLS AND CRIME. 321 bounds of political liberty, enhanced the nation's wealth, and con- tributed so largely to its power ? It, however, is further claimed, and almost universally allowed, that the instruction of our public schools serves to ennoble the emotions and to moderate the passions, to regenerate the viciously inclined, and to correct and subdue the tendency to crime. De- voutly as such a result is to be desired, the facts unhappily flatly contradict the theory, and unless the glaring inconsistencies are reconciled, and contravening evidence is satisfactorily explained, the claim must be abandoned as unfounded. At a session of the National Prison Congress, held in Boston during 1888, Mr. Brooker, chairman of the Board of Directors of the South Carolina Penitentiary, having made the statement that of a thousand convicts in the State not more than fifty were whites, it was asked by a delegate, " What is the condition of the education of the colored people ? " To this question Mr. Brooker made the following reply : " Before emancipation, the colored peo- ple had no opportunity for education. When made suddenly free, all negroes were illiterate and ignorant. Since that time a young generation has grown up, and of them a very considerable number are well educated. But it is a fearful fact that a large proportion of our prison population is of tlie educated class. This is so much the case that the idea has become prevalent that to educate the negro is to make him a rascal. But this idea is of course superficial, and does not find lodgment in the minds of thoughtful men. I am totally averse to it myself, and think that all reasonable means should be exerted toward their enlighten- ment and education." (" Proceedings of the National Prison Asso- ciation/' 1888, p. 72.) The constructing engineer is to our industrial, commercial, and mechanical development all that the statesman and student of sociology is to our moral, social, and political progress. If in a convention of engineers a verified report had been made that bridges of accepted form were showing visible signs of weakness, the report would have been listened to with the greatest con- sternation and dismay. The convention would have instituted the closest inquiry and most searching examinations; it would have stopped the construction of such bridges until the causes of failure had been determined and the remedy ascertained, and failing in this the construction of such bridges would have been permanently abandoned and more perfect structures substituted. But here was the most astounding fact that in South Carolina, which in 1880 had more than half its population returned as illiterate, the educated negroes furnished a large proportion of its criminals, pressed upon a representative body of philanthro- pists, publicists, and statesmen, and it did not so much as provoke 322 THE POPULAR SCIENCE MONTHLY. a comment, while the author of the statement boldly affirmed his unshaken faith in a theory the facts of which he had himself impugned. What deference should we pay to thought unless based upon correct observations, and of what utility are facts and experiences unless their teachings are heeded and their meaning properly interpreted ? In his "Political Science" Woolsey tells us that "the fall of the Roman Empire was an effect of a moral ruin." Yet all will admit that Rome and the other civilizations of antiquity were richer and more learned in the time of their decay than during the period of their infancy and growth ; but the moral correlative being wanting, they tottered to their fall. Just look at the records of our mentally and morally deranged as exhibited in our statistics of insanity and crime and vice, and they alone are enough to cast doubt upon the claim that a public- school education for our illiterates is sufficient to insure a decrease of mental and moral delinquency. For it remains to be explained why, in the decade ending with 1880, population having increased thirty per cent and illiteracy only ten per cent, a relative decrease ; that the number of criminals during the same period present the alarming increase of eighty-two per cent, while of insane persons there appears the enormous addition of one hundred and forty- five * per cent ? Can it be possible that with greater educational facilities there is to be increased crime, and that every enlargement in the seat- ing capacity of our schools is to be followed by a larger corre- sponding demand for insane accommodations, and additional felons' cells ? Perish the thought ! Yet if the instruction of our common schools subdues the tendency to crime, why is it that the ratio of prisoners,! being one in 3,442 inhabitants in 1850, rose to one in every 1,647 in 1860, one in 1,021 in 1870, and one in 837 in 1880 ; while, upon the authority of the Rev. S. W. Dicke, the amount of liquor consumed per capita was three times as great in 1883 as in 1840 ? One naturally looks to the large and constant influx of foreign immigrants as a partial explanation of this growing dispropor- tionate increase of crime ; but the facts deny the hope, for the great increase is to be found among the native-born. The Rev. F. H. Wines, who conducted this branch of the " Tenth Census Report," says that, while in 1850 the ratio of foreign criminals to population was five times that of the native-born, in 1880 the * It is but fair to state that this enormous increase of insanity has led the compiler to question the accuracy of the returns of insane persons made in 1870, yet it is admitted that, after making every allowance, the ratio of increase is out of all proportion to that of population. (See page 1660, "Compendium of the Tenth Census.") \ "Proceedings of the National Prison Congress," 1886, p. 134. PUBLIC SCHOOLS AND CRIME. 323 ratio was only two to one ; and if we deduct the commitments for disorder and immorality, the ratio of foreign criminals is but little in excess of that for native whites. So clearly is this indicated by facts and figures, that Mr. Wines arrives at the conclusion that " the foreign disregard for law shows itself far more in im- morality and disorder than in dishonesty and violence." * An examination of the " Compendium of the Tenth Census " of the United States discloses some novel and threatening facts. The illiterates of the United States comprise seventeen per cent of the total population. The morally and mentally deranged, as shown by the number of criminal and insane persons, bear the ratio of one to every 332 inhabitants. The general average of illiteracy is exceeded by every one of the original slave States with the exception of Missouri, but the average ratio of the men- tally and morally unsound is only reached in the State of Mary- land. South Carolina, which shows the highest percentage of illiterates, viz., 55^ per cent, presents the lowest average of any State in the Union as regards insanity and crime, having but one delinquent in every 568 inhabitants as compared with one in every 167 in California, one in 205 in Massachusetts, and one in every 222 in the State of New York. With the single exception of the State of Maine, every Northern State east of Indiana has a larger ratio of insane and criminals than the average for the Union, while the States west of Ohio, those on the Pacific slope excepted, fall below the general average. If we measure the extent of unrecorded vice by the proportion of saloons to population, the showing is no less remarkable. The " Report of the Commissioner of Internal Revenue for the Year 1887," page xxxiii, shows that, for the entire country during that year, a retail license for selling liquor was granted for every 329 inhabitants. Of the fifteen States showing more than the average number of illiterates that ratio was only exceeded in the State of Louisiana; while the lowest average in the country was to be found in Mississippi, which, with 49155- per cent of its inhabitants returned in 1880 as being illiterate, supported but one saloon for every 1,695 persons. Even the prohibition States of Maine and Kansas secured licenses for the sale of intoxicants at retail to an extent only equaled by four of the fifteen super-illiterate States. The proportion of saloons to population throughout the fifteen super-illiterate States is one for every 700 inhabitants, while of the other States California heads the list with one to every 99 persons, New Jersey coming next with one license to every 171 inhabitants, followed closely by New York with one to every 179. The table which follows presents some disquieting facts, which * "Proceedings of the National Prison Association," 1888, p. 255. 324 THE POPULAR SCIENCE MONTHLY. should serve as a salutary warning to those who expect to find in mental stimulation an equivalent for moral growth and culture : Compiled from Compendium of Tenth Census, and other official sources.

But we need not confine ourselves to the general statistics of the United States, for the records of New York present similar conditions, which can be analyzed more in detail. The " Annual Report of the Superintendent of the New York State Prisons, 1886," records that the prisons of Auburn and Sing Sing contained 2,610 convicts; of these, 1,801 are credited with a common-school education, 373 are classed as being able to read and write, 19 are returned as collegiates, 10 as having received classical and 78 academic educations, 97 as being able to read only, and 238 as having no education. Is it not contrary to our most confident predictions and undoubted expectations that the common schools should furnish eighty-three per cent and the colleges and acade- mies over four per cent of the inmates of Auburn and Sing Sing ? # When it is remembered that the detected illiterate generally finds his way to prison, while the highly educated or well-to-do are frequently saved by friends, who compound the felony to escape exposure and consequent family disgrace ; that many are saved from conviction by the ability of counsel whose services are far beyond the means of the illiterate poor, while still many others escape into voluntary exile to avoid imprisonment, it will be seen that even the figures given inadequately portray the ex- tent of crime which, in strict justice, is properly chargeable to the educated classes. Of the prisoners of Auburn and Sing Sing it * Includes all States having a percentage of illiteracy above seventeen per cent, the av- erage for the entire country. f Computed from tables in Compendium of the Tenth Census. % Retail licenses issued by United States in 1887, taken from Report of Internal Rev- enue Commissioner.

PUBLIC SCHOOLS AND CRIME. 325 is further noted that twenty per cent were total abstainers from intoxicants, showing very clearly that a perfect mastery of self is by no means necessarily allied with an honest regard for the rights and property of others. But if the education of the masses is accompanied by no dimi- nution of vice, crime, and insanity, what shall we say of the effect illiteracy may have upon our institutions by the abuse or misuse of the suffrage ? The following extract from the address of the Rev. J. C. Hartzall, delivered before the National Education As- sembly at Ocean Grove, in August, 1885, which, with other ex- tracts, is incorporated in the speech of Senator Blair on his Edu- cational Bill, delivered in the Senate, February 8, 188G, presents a fair example of the rather extravagant statements often made by publicists and statesmen concerning the dangers attending the ex- ercise of the elective franchise by illiterate voters. The reverend doctor thus appealed to the Assembly : " I simply call your atten- tion to what may be the injurious effect of their (illiterates) silent action at the polls. The members of our respective political par- ties believe in the Tightness of their principles, and seek to make their appeal to the reason and the consciences of the people ; but the figures disclose the alarming fact that in eleven States these illiterate voters outnumber the votes cast in the last presidential (1884) election by either of the political parties. Thus, should they unite under any strong, impassioned, successful leader, they would have absolute control of legislation and offices in those States, and of the election of twenty-two members of the United States Senate." Only a moment's thought is necessary to expose the folly of such ill-founded fears, for the suggested peril is contravened by the very conditions set forth as dangerous, as the inability to read and write affords a complete and absolute bar against the possi- bility of such concerted action ; for what means of communication are to be employed to unite, for a single purpose, the illiterates of eleven States, who can neither read letters, circulars, documents, nor newspapers, and, still further, are unable to write answers in return ? It requires the most perfect organization, careful can- vass, and the expenditure of vast sums of money, to bring out a full vote where conditions are the most favorable for it, in the enlightened and thickly settled portions of the Union, and only where States are very evenly divided is the organization so per- fected, at great cost, as to make a full vote possible. But the election returns themselves are sufficient to prove that the voters in the illiterate States adhere more closely to the two great parties which are said to " appeal to the reason and con- sciences of men " than do the voters of the States affording the best facilities for the education of the masses ; and in the election 326 THE POPULAR SCIENCE MONTHLY. referred to in the address, the fifteen super-illiterate States com- bined cast but twenty-five per cent of the Greenback vote polled by the single State of Michigan, while in the late presidential election the same fifteen States cast but ten per cent more Labor- Union votes than were cast in the State of Kansas alone, and nine of the super-illiterate States fail to record the polling of a Union-Labor vote. Far from mental stimulation being essential to moral devel- opment, the most perfect order and deepest sense of justice are often found associated with the densest ignorance among the low- est races of humanity. Turn your attention to the Papuan-Isl- anders,* the Veddahs,f the Dyaks of Borneo,! the Fuegians,* and other barbarous races which, in the absence of rulers or organ- ized societies, with no learning and but little acquaintance with even the rude arts of many primitive people, have developed the highest degree of tribal piety, integrity, chastity, and regard for covenants almost unknown to civilized man. The testimony of early travelers proves conclusively that intense poverty and deep ignorance are by no means incompatible with honesty, integrity, and virtue. The table shows that where the extremes of poverty and wealth prevail, as in the Eastern States, there is found a maxi- mum of moral and mental derangement, as exhibited in insanity, crime, and vice. Where wealth is more evenly distributed, as in the "Western States, there are noted less insanity and crime, but almost as high a ratio of saloons as in the East. In the Southern States, although having a low per capita of wealth, yet the men- tal and moral forces of development are more nearly in adjust- * " It is worthy of remark that these simple islanders, without hope of reward or fear of future punishment after death, live in such peace and brotherly love with one another, and that they recognize the right of property in the fullest sense of the word, without there being any authority among them other than the decision of their elders, according to the customs of their forefathers, which are held in the highest regard." (Earl Kolff's " Voyages of the Dogma," p. 161.) f " The Rock Veddahs are divided into small clans, or families, associated for relation- ship, who agree, partitioning the forests among themselves for hunting-grounds, the limits of each family's possession being marked by streams, hills, rocks, or some well-known trees, and these conventional allotments are always honorably recognized and mutually pre- served from violation. Each party has a head man, the most energetic senior of the tribe, but who exercises no authority except distributing at a particular season the honey capt- ured by the members of the clan." (Tennant, ii, p. 440.) % " The Dyaks' minds are as healthy as their bodies ; theft, brawling, and adultery are unknown to them." (Boyle's " Borneo," p. 335.) "The Dyaks are manly, hospitable, honest, kindly, and humane to a degree which might well shame ourselves." (Ibid, p. 215.) * " Nothing like a chief could be made out among the Fuegians of Blunder Cove, nor did they seem to require one for the peace of their society, for their behavior one to another was most affectionate, and all property seemed to be possessed in common."

The Rev. F. H. Wines, statistician and philanthropist, who has made questions of crime and criminals the study of a lifetime, was selected by the authorities at Washington to compile the statistics bearing on delinquents in the tenth census ; and after a careful study of the mass of figures returned, but few of which appear in the compendium, he makes this very remarkable statement con- cerning the facts collected and enumerated : " If a comparison is made between offenses against public morals and against public peace, the smallest amount of disorder and the largest of immo- rality, relatively, are found among the native whites, the most disorder and least immorality among the negroes; and the for- eigners occupy a middle ground between the two." (" American Prisons in the Tenth Census," " Proceedings of the National Pris- on Association for 1888," p. 268.) When it is realized that the native whites represent the better educated portion of our popu- lation, and the negroes the more illiterate, while the foreigners are on an educational scale between the two, the significance of the statement can neither be gainsaid nor belittled. We are, then, confronted by facts which reveal a condition of decreasing illiteracy and increasing crime, of augmenting wealth with more wide-spread destitution. While inventors and engineers have united continents by steamship lines and cables, States by telegraph and railway lines, and cities by bridges, statesmen have vainly sought to unite the interests of employers and employe's, of railway managers and shippers, of producers and consumers ; and every legislative measure intended to har- monize the interests of these conflicting elements has given rise to greater irritation and more complicated evils. Since the record of material progress and mechanical construc- tion has been one of unvarying certainty and triumph, while leg- islation has so often led to failure in the investigation of this edu- cational problem, will it not be well to reject the hap-hazard devices of the legislator, and confine ourselves to the scientific methods so successfully employed by the constructing engineer and mechanical inventor ? Take, for illustration, the history of Bessemer steel railway-bars. The introduction and use of these bars for our railway -tracks so cheapened the cost of transporta- tion that it made possible the development of the far Western States and Territories, which find themselves enabled to profitably market produce thousands of miles away. Twenty years ago, under a traffic which constituted but a small fraction of the mileage which the same roads are perform- ing to-day, iron rails became worn down and laminated with such rapidity that the cost of track repairs was enormous, and it 328 THE POPULAR SCIENCE MONTHLY. was by no means uncommon for iron rails to be removed from the track worn out before they bad been subjected to a single season's wear. About that time the Bessemer steel rail was in- troduced, and its hard, homogeneous metal offered great resist- ance to the wear and abrasion of the rolling wheels. But a new difficulty appeared ; for, while the steel rails suffered but little from wear, they developed a provoking tendency to break with- out giving any previous warning, which served to increase the danger of railroad traveling. Upon the discovery of this evil, the engineers in charge neither discarded the Bessemer rails, nor did they close their eyes to its obvious defects, but, in imitation of our social concerns, they kept acurate statistics of the life and breakage of the rails, and finally discovered that, in the effort to resist the tendency to wear, they had gone so far as to make the metal brittle ; hence the saving to wear was partly lost because of the failure of rails by breaking. Less carbon was put into the steel, and a softer metal was produced, which, while vastly supe- rior to iron as against lamination and abrasion, was sufficiently soft to avoid the breaking, with its attendant dangers. Do not the facts disclosed by our social statistics cause it to appear that, in the adjustment of our schools, we have gone too far in our aim for material advancement and development of wealth, and that we are correspondingly losing in the direction of moral growth and culture ? Let us, then, imitate the prudence of the railway engineer, and, though seeking to retain the ad- vantages which are already ours, let us not be blind to the visible defects and besetting dangers of our present system. Let us de- termine the composition of the training of our public schools; let us see if its parts are well proportioned and the compound skillfully wrought, and a thorough analysis may prove, as with the Bessemer steel rail, that, by a judicious change in the nature or proportion of the ingredients, our rapid increase of wealth may suffer a trifling diminution, but the moral balance of educa- tion will be restored, and material, political, and moral progress will move forward together. Is his presidential address to the Royal Geographical Society, President Strachey, assuming that the last barrier excluding us from unknown regions would soon he broken through, named the establishment of the supremacy of modern civilization and progress over Africa as the next geographical problem. That con- tinent presents wholly different conditions from any other land that has been brought under civilization, and will call for different methods of management. It can not be directly colonized, as were North America and Australia, or adminis- tered as India is ; and amalgamation between European settlers and the indigenous races is wholly out of the question. The operation will necessarily be a long and, in some respects, a painful one. THE TA0U1ST RELIGION. 329 THE TAOUIST RELIGION. By WARREN G. BENTON. IN an attempt to unravel the mysteries of the religions of the Chinese, one is confused at the outset by the almost obliter- ated lines between the three leading forms of religion existing side by side. The process of amalgamation has gone on for so many centuries that one is liable to be misled in an effort to ana- lyze the different creeds. The fact is that Buddhism, Taouism, and Confucianism have existed in the same minds until a belief in the distinctive phases of each has become quite common. And even those who nominally accept the Christian religion, either Catholic or Protestant, really add the new to the old faiths, and believe more or less in the four religions. It is thus true that in one mind may be found a belief in four primarily distinct and separate religions — each having added its quota toward a result whose aggregate beliefs are derived from wholly dissimilar sources ; and the result is, as might be looked for, a unique speci- men of religionist. In this paper I shall endeavor to indicate the particular feat- ures of Taouism. This system of religion is pronounced indigenous to China. Its founder was one Laou-tse, who is supposed to have lived con- temporary with Confucius, and to have been some years older than that celebrated philosopher. The word Taou signifies rea- son, and therefore a Taouist is a rationalist, in name at least ; but, in fact, the Taouists are the most irrational of all the religionists of the East. The tendency in rationalism is toward the utter destruction of belief in the existence of unseen spirits of evil. Enlightened rea- son dethrones devils; but Laou-tse created devils innumerable, and the chief concern of the Taouist sect has always been to manipulate these emissaries of evil. Modern rationalists deny the existence of devils, and relegate them to the category of myths and to personified ideas. Not so the rationalist of the Orient. He finds his greatest pleasure in contemplating the very atmosphere he breathes as filled with spirits constantly seeking his injury ; and to outwit his satanic majesty is the chief end of life. The sect is founded on the monarchic plan. The chief high priest corresponds to the Pope in the Catholic religion, and all authority is vested in him. His decrees constitute the laws of the sect, and all power to perform miracles must come from him to the priesthood. He has the power to exorcise devils and to heal VOL. XXXTI. — 21 33o THE POPULAR SCIENCE MONTHLY. the sick and avert calamities, and this power he delegates to such of the priesthood as command his favor. Such delegated power, however, is held on sufferance, and not in fee-simple. It is not only necessary that a priest gain favor with his royal highness to get this power, but he must retain said favor in order to hold the power. This has created a vast army of priests, who are the willing tools of the high priest ; and he is thus enabled to wield the most absolute and despotic sway over the minds of the people. The system has the most elaborated code of demonology, and it is likewise patterned after the political constitution of the empire. The head devil lives in the sea, and has been honored by the Chinese people by being adopted as their national emblem. The dragon flag, which floats from every staff, from the dome of the royal palace at Pekin to the mast-head of the humblest Chi- nese boat, testifies to the high esteem in which the chief devil of Laou-tse's followers is held. Then the multitude of lesser devils is so great that no man can number them ; and these are on the track of every man, woman, and child, seeking in all methods their injury. To watch the movements of this devil host, and to frustrate their designs, is the province of the Taouist priests. Here we have a decidedly interesting state of things. The very earth teeming with malicious demons ! Man everywhere exposed to their attacks, and but one avenue of escape, viz., through the interventions of the priests ! Is it a matter of sur- prise, therefore, that this priesthood wields such absolute power over the minds of the people ? They live on the fat of the land. They are consulted on all occasions, and their instructions are obeyed to the letter by their deluded followers. It is not to be wondered at that these priests look with disfavor upon the advent of Europeans ; that they fill the minds of the people with such antipathy to all change from the established order. They are wise enough to forecast their own overthrow with the advent of a deeper intelligence. The priests are celibates, perhaps with the thought that, if they were to prove unequal to the task of managing a wife, their prestige in devil manipulation might suffer. They keep aloof from the common life around them and live in mountains and unfrequented and isolated places, that they may the better im- press their own superiority over their fellows. The priests are called upon by the people when it is discovered that a home or village is infested by a devil. Devils have the power to materialize themselves into a piece of waste paper or dirt in order to get into the houses unobserved. These devils are not credited with a high order of intelligence. Chinese archi- tecture is governed by this conception. The doors or main en- trances are put in unexpected angles and niches in the walls, with THE TAOUIST RELIGION. 33i the idea that they will fool the devils. They cut up the roof -lines on dwellings into fantastic shapes for the purpose of preventing devils using them for promenade purposes ; and, as a matter of fact, these imps have hard work to get into the houses. But, when they once get in, no power is able to get them out except the priests. The white horse is a common form in which devils infest a community. They appear in the form of a white horse walking upon the city walls, and over graveyards, and even stepping from one roof to another. He is thus seen by some truthful wit- ness, and the evil omen soon gains currency. The intervention of the nearest priest is sought, who takes a survey of the situation, and discovers the number of devils, if more than one, and calculates on the necessary steps to capture it or them. The financial ability of the community has much to do in determining the means of safety. If the locality is wealthy, or has a few wealthy men in it, the priest generally makes out a strong case. He may require to call in other priests in consulta- tion. All this time the people dwell in morbid fear, pending de- liverance. At length the priests announce their ultimatum. It will require a fee of one hundred taels (about one hundred and thirty-three dollars, American money) to procure safety. The money is raised by public subscription and paid over to the priest in charge. Then the capture of the devils is the next step. A bottle or jar is secured for each devil, and the priests secure a bait in the shape of imitation gold and silver tinted paper (called Joss paper). This paper is imitation money, and when it is reduced to spirit by being burned, the devils do not know it from genuine money — here again showing their low mentality — and they enter the bottle in which the Joss paper has been burned. When they are thus entrapped, the bottle is sealed and carried away by the priest. Then the people feel grateful to their deliverer, and the priest has again impressed his importance to the welfare of the community and at the same time replenished his bank account. The " Tsung li Yamen," or office of the head priest of this sect, is a curiosity. It has large halls and rooms filled with dust-covered and sealed jars, in every one of which is confined a devil, captured in the above unique plan. And were each and every jar filled with silver, I question if it would equal the sums paid for the capture of these imprisoned devils. This demonology enters into every phase of Chinese life. The priest is the only medium between the people and their invisible foe. Not a voyage is undertaken until the devils are baited by burning bogus paper money. Not a wedding, but the priest is called in to decipher the omens for good or ill luck. And when a man is sick, 332 THE POPULAR SCIENCE MONTHLY. he is possessed of devils. Chills are the most common form of possession. "What makes a man shake if he is not in the power of a devil ? So the people believe, and a priest is called instead of a doctor, and prayers take the place of pills. Epileptic fits or convulsions are the devil in a malignant form ; and if a man is taken thus in a crowded building, that building is rapidly de- serted. A good doctor could go among the Chinese and, by curing the sick, attending his physic by incantations, enthrone himself as a deity in the belief of that deluded people. When a man is dying, no money would induce a Chinaman to remain near him. I first met this fact on a Pacific steamer bound from San Francisco to Hong-Kong. I was walking on the deck with the ship's sur- geon, when a stream of Chinamen came rushing on deck from the lower decks like a colony of ants when disturbed. I asked what had caused such a stampede. The doctor replied that a China- man was dying. He hurried below, and found a man gasping his last breath, with consumption. I discovered later, when pursuing my studies of Chinese religions, the secret of this strange stam- pede. The devil was after the soul of that poor consumptive, and the rest were not going to take any chances by remaining near him in the final struggle. Not every wise-looking magpie or crow, which alights upon the bough of a tree to rest, is the innocent creature it appears to be ; but a devil in disguise spying out the lay of the land. Nor do the frightened people seek relief by killing the bird of evil omen, but they call a priest to look into the matter. He generally advises that the tree be cut down in the night and removed. Thus, when the devil, alias a magpie, returns to his perch, he is fooled, and thus thrown off the track. The ceremonies so often observed on occasions of death all have their origin in the demonology of the Taouists. Paper suits, paper palaces, paper pipes and money are burned when a man dies, to provide the soul of the dead with means of bribing its way through the devil's kingdom to its rest, and the suits burned are often patterned after high officials' gowns, in order to im- press more favorably the spirits encountered on the mysterious journey. Taouist priests are called to consult the soul of the departed to ascertain its wishes. They discover the locality for burial, and indicate all details of this last service to the dead. The Shanghai Railroad met its doom from this source. The priests informed the people that the rumbling noise of the cars and the steam-engine were distasteful to the dead who filled the numerous mounds along its course. To appease the wrath of the dead, Chinese capitalists bought the road with its equipments, THE TA0UI8T RELIGION. 333 and tore up the tracks and stored the entire plant under sheds at Shanghai. Thus it is seen that this religion stands in the way of all innovations in that old country, and the first thing necessary in order to introduce railroads into China is to dethrone the priests and infuse a little common sense into the people. Since this last paragraph was written, this point has had a characteristic demonstration. Through the influence of Li Hung Chang, the most intelligent and progressive Chinaman, and one or two other high officials, the emperor was prevailed upon to grant the construction of a railroad from Hankow to Pekin. Not many days had elapsed after the permit was given until the Tem- ple of Heaven at Pekin was burned, and floods came in the Yel- low and Yang-tse River Valleys, which were interpreted to have been indications of the disapproval of the proposed innovation on the part of spirits or the Taouist devil ; and the press dispatches announce that the emperor has taken the timely warning and re- voked his sanction of the proposed railroad. Any one having to make the journey between the two objective points of the pro- posed road will save time by starting on foot, or going around via Shanghai by water. Otherwise he is liable to have a long time to wait for the completion of the road. During the prevalence of the great famine in northwestern China in 1874-'78 there was an unusual flood in the valley of the Yang-tse-Kiang. The priests endeavored to solve the mystery of this uneven distribution of rain. The censure fell upon the royal household at Pekin. It is the duty of the emperor to enter the Temple of Heaven twice a year and invoke the blessings of Heaven upon the people. He always asks for rain among other things, and the impression obtained that the emperor had hurriedly asked for rain, but had not taken the pains to state where he wanted it. The result was that floods came in some places, while famine from drought came in other parts of the empire. This feeling was pro- ducing a general spirit of revolt, when in 1878 the rains came to the rescue in the drought-smitten provinces. At this time I had a conversation with a merchant at Shanghai on the subject. He exhibited an independence of thought which was exceptional. But it showed a tendency toward the inevitable break from the tyrannical rule of ignorance and superstition which must eventually come to awaken an age of reason. And when it comes, the Taouist high priest must fold his tent and silently march away. The merchant said, " Chinaman, he all time chin, chin " (mean- ing that they resort to prayers and other priestly methods in time of calamity), "while Melican man, he build more stout walls to keep water back." Thus had one man concluded that substantial sea-walls and 334 THE POPULAR SCIENCE MONTHLY. dikes were more availing in times of flood than prayers as a pro- tection from encroaching waters from overflowing rivers. But the dominance of ignorance and the quackery of priests will hold China in slavery to an unreasoning fear and irrational faith for generations yet unborn. Yet the seeds of a better intel- ligence are being planted in this dark corner of the earth. The people observe that Europeans give no heed to imaginary devils, and still they prosper without the intervention of priests; and thus will eventually dawn upon them how grievously their fore- fathers have been hoodwinked, cheated, and robbed by the reign of demonology, created and perpetuated for their own gain by the army of Taouist priests. -♦♦♦- LETTERS ON" THE LAND QUESTION. By HERBERT SPENCER, FREDERICK GREENWOOD, Professor HUXLEY, Sib LOUIS MALLET, and JOHN LAIDLER. THE following letters, reprinted from the London " Times " of • recent dates (from November 7 to 15, 1889), are of great in- terest on account of the light they throw upon some of the more important aspects of the question of land nationalization, and on the problems of socialism in general. — Editor.] MR. SPENCER'S FIRST LETTER. To the Editor of " The Times " : Sir: During the interview between Mr. Morley and some of his constituents, reported in your issue of the 5th inst., I was re- ferred to as having set forth certain opinions respecting land-own- ership.* Fearing that, if I remain silent, many will suppose I * Extract from the Morley Interview. Mr. Laidler said their method of dealing with the land would be that the present owners should hold it for their time, and that it should revert back to the State. They re- membered that Mr. Herbert Spencer had said that the land had been taken by force and by fraud. That gentleman had also said that to right one wrong it takes another. Mr. Morley. — Has Mr. Spencer said this ? Mr. Laidler. — Yes ; we all know. Mr. Morley. — You are aware that he has recalled some of the things he has laid down? Mr. Laidler. — If he has stated truth and recalled it, the truth will prevail. Mr. Morley. — Do you include houses ? Mr. Laidler. — We include land, not houses. In houses there is labor, but in land there is not. Mr. Morley. — Not? Mr. Laidler. — There may be labor exerted in land, but as far as the labor is in the land we believe it ought to belong to the laborer. As the land has been obtained by the method I have named — by force and fraud, as Spencer says — we contend that the land ought to be taken back by the community and handed over to the municipalities and county councils to be used in such democratic manner as the people may elect those bodies for. Mr. Morley.— I can not think that what is commonly called nationalization of the land LETTERS ON THE LAND QUESTION 335 have said things which I have not said, I find it needful to say- something in explanation. Already within these few years I have twice pointed out that these opinions (made to appear by those who have circulated them widely different from what they really are, by the omission of ac- companying opinions) were set forth in my first work, published forty years ago ; and that, for the last twelve or fifteen years, I have refrained from issuing new editions of that work and have interdicted translations, because, though I still adhere to its gen- eral principles, I dissent from some of the deductions. The work referred to — " Social Statics " — was intended to be a system of political ethics — absolute political ethics, or that which ought to be, as distinguished from relative political ethics, or that which is at present the nearest practicable approach to it. The conclusion reached concerning land-ownership was reached while seeking a valid basis for the right of property : the basis assigned by Locke appearing to me invalid. It was argued that a satisfac- tory ethical warrant for private ownership could arise only by con- tract between the community, as original owner of the inhabited area, and individual members, who became tenants, agreeing to pay certain portions of the produce, or its equivalent in money, in consideration of recognized claims to the rest. And in the course of the argument it was pointed out that such a view of land-own- ership is congruous with existing legal theory and practice ; since in law every land-owner is held to be a tenant of the Crown — that is, of the community, and since, in practice, the supreme right of the community is asserted by every Act of Parliament which, with a view to public advantage, directly or by proxy takes pos- session of land after making due compensation. All this was said in the belief that the questions raised were not likely to come to the front in our time or for many genera- tions ; but, assuming that they would some time come to the front, it was said that, supposing the community should assert overtly the supreme right which is now tacitly asserted, the business of compensation of land-owners would be a complicated one : One that perhaps can not be settled in a strictly equitable manner. . . . Most of our present land-owners are men who have, either mediately or immediately, either by their own acts or by the acts of their ancestors, given for their estates equivalents of honestly earned wealth, believing that they were investing their savings in a legitimate manner. To justly estimate and liquidate the claims of such is one of the most intricate problems society will one day have to solve. To make the position I then took quite clear, it is needful to add that, as shown in a succeeding chapter, the insistence on this is anything but what it was called the other day — either robbery or folly. I have really no more to say on that subject. 336 THE POPULAR SCIENCE MONTHLY. doctrine, in virtue of which "the right of property obtains a legitimate foundation/' had for one of its motives the exclusion of Socialism and Communism, to which I was then as profoundly averse as I am now. Investigations made during recent years into the various forms of social organization, while writing the " Principles of Sociology," have in part confirmed and in part changed the views published in 1850. Perhaps I may be allowed space for quoting from " Po- litical Institutions " a paragraph showing the revised conclusions arrived at : At first sight it seems fairly inferable that the absolute ownership of land by private persons must be the ultimate state which industrialism brings about. But though industrialism has thus far tended to individualize possession of land while individualizing all other possession, it may be doubted whether the final stage is at present reached. Ownership established by force does not stand on the same footing as ownership established by contract; and though multiplied sales and purchases, treating the two ownerships in the same way, have tacitly assimilated them, the assimilation may eventually be denied. The analogy furnished by as- sumed rights of possession over human beings helps us to recognize this possibility. For, while prisoners of war, taken by force and held as property in a vague way (being at first much on a footing with other members of a household), were re- duced more definitely to the form of property when the buying and selling of slaves became general ; and, while it might centuries ago have been thence in- ferred that the ownership of man by man was an ownership in course of being permanently established, yet we see that a later stage of civilization, reversing this process, has destroyed ownership of man by man. Similarly, at a stage still more advanced, it may be that private ownership of land will disappear. As that primitive freedom of the individual which existed before war established coercive institutions and personal slavery comes to be re-established as militancy declines, so it seems possible that the primitive ownership of land by the community, which, with the development of coercive institutions, lapsed in large measure or wholly into private ownership, will be revived as industrialism further develops. The regime of contract, at present so far extended that the right of property in mova- bles is recognized only as having arisen by exchange of services or products under agreements, or by gift from those who had acquired it under such agreements, may be further extended so far that the products of the soil will be recognized as property only by virtue of agreements between individuals as tenants and the community as land-owner. Even now, among ourselves, private ownership of land is not absolute. In legal theory land-owners are directly or indirectly tenants of the Crown (which in our day is equivalent to the State, or, in other words, the community) ; and the community from time to time resumes possession after making due compensation. Perhaps the right of the community to the land, thus tacitly asserted, will in time to come be overtly asserted and acted upon after making full allowance for the accumulated value artificially given. . . . There is reason to suspect that, wrhile private possession of things produced by labor will grow even more definite and sacred than at present, the inhabited area, which can not be produced by labor, will eventually be distinguished as something which may not be privately possessed. As the individual, primitively owner of himself, partially or wholly loses ownership of himself during the militant regime, but gradually resumes it as the industrial regime develops, so possibly the communal LETTERS ON THE LAND QUESTION. 337 proprietorship of land, partially or wholly merged in the ownership of dominant men during evolution of the militant type, will be resumed as the industrial type becomes fully evolved (pp. 643-646). The use of the words " possible," " possibly," and " perhaps " in the above extracts shows that I have no positive opinion as to what may hereafter take place. The reason for this state of hesi- tancy is that I can not see my way toward reconciliation of the ethical requirements with the politico-economical requirements. On the one hand, a condition of things under which the owner of, say, the Scilly Isles might make tenancy of his land conditional upon professing a certain creed or adopting prescribed habits of life, giving notice to quit to any who did not submit, is ethi- cally indefensible. On the other hand, "nationalization of the land," effected after compensation for the artificial value given by cultivation, amounting to the greater part of its value, would entail, in the shape of interest on the required purchase-money, as great a sum as is now paid in rent, and indeed a greater, con- sidering the respective rates of interest on landed property and other property. Add to which, there is no reason to think that the substituted form of administration would be better than the existing form of administration. The belief that land would be better managed by public officials than it is by private owners is a very wild belief. "What the remote future may bring forth there is no saying ; but with a humanity anything like that we now know, the im- plied reorganization would be disastrous. I am, etc., Herbert Spencer. Athenaeum Club, November GOi. MR. GREENWOOD'S LETTER. To the Editor of "The Times" : Sir: Mr. Herbert Spencer's letter in "The Times" of to-day carries with it a heavy lesson to political philosophers. They are taught to remember that this is an age of popular education, as well as of social unrest ; that their books are read not only by students like themselves, who often find their chief interest in a display of intellectual subtlety or athleticism, but by thousands of men who are ever on the alert for warranted theories of social reform that will better their condition. And if such theories should happen to be ill-considered before publication, or unaccom- panied by a strong and clear recital of whatever reasons are fatal to their application in this work-a-day world, the mischief they may do is enormous. How clearly Mr. Spencer himself must see this now ! And how sorry he must be for having so terribly mis- led, not Mr. Laidler and the Labor party of Newcastle alone — that 338 TEE POPULAR SCIENCE MONTHLY. is not imaginable — but many other poor men also who habitually hang on the authority of great men like himself. It was when Mr. Morley was so delicately heckled at New- castle that a member of the Labor party deputation asked him what he thought about the nationalization of the land. Mr. Morley demurred. Mr. Laidler said the Labor party had its own plan. " They remembered that Mr. Herbert Spencer had said that the land had been taken by force and fraud ; that gentleman had also said that to right one wrong it takes another." " Why," re- plies Mr. Morley, " has he said this ? " " We all know he has/' rejoins Mr. Laidler. "But you are aware that he has recalled some of the things he has laid down ? " " Yes," rejoins Mr. Laidler ; " but if he has stated truth and recalled it the truth will prevail." There we are. This little bit of conversation is pre- cious beyond many pages of "absolute political ethics," judged by the standard of usefulness ; and it will be useful to nobody so much as to writers like Mr. Herbert Spencer. For what has he to say to it all ? He says that the opinions quoted by Mr. Laidler were set forth forty years ago in a work " intended to be a system of absolute political ethics ; or that which ought to be, as distinguished from relative political ethics, or that which is at present the nearest practical approach to it." These opinions were accompanied by others which forbid the interpretation sometimes put upon them. But yet, on reflection, they satisfied Mr. Spencer so little, he thought them so little guarded or corrected by those other opinions of his, that for the last fifteen years he has not allowed the book that contained them to appear in any language. " Though I still adhere to its general principles, I dissent from some of the deductions" — those, per- haps, which Mr. Laidler regards as truth once uttered and never to be recalled. Besides, what Mr. Spencer said on this subject " was said in the belief that the questions raised were not likely to come to the front in our time or for many generations " ; and it did include the statement that, if the community took the land, the necessary business of compensation would be a complicated one. " To justly estimate and liquidate the claims " of our pres- ent land-owners " is one of the most intricate problems society one day will have to solve." Since " Social Statics " was published, however, Mr. Spencer has come to revised conclusions; and these he now sets forth in " The Times." Permit me to quote a few sentences from this statement : Though industrialism has thus far tended to individualize possession of land, while individualizing all other possessions, it may be doubted whether the final stage is at present reached. Ownership established by force does not stand on the same footing as ownership established by contract; and though multiplied sales and purchases treating the two ownerships in the same way have tacitly assimi- LETTERS ON THE LAND QUESTION. 339 lated them, the assimilation may eventually be denied. . . . There is reason to suspect that, while private possession of things produced by labor will grow even more definite and sacred than at present, the inhabited area, which can not be produced by labor, will eventually be distinguished as something which may not be privately possessed. . . . Possibly the communal proprietorship of land, par- tially or wholly merged in the ownership of dominant men during evolution of the militant type, will be resumed as the industrial type becomes fully evolved. After quoting these and similar passages from his revised opinions, Mr. Spencer makes the following observations: "The use of the words ' possible/ 'possibly/ and ' perhaps/ in the above extracts shows that I have no positive opinion as to what may- hereafter take place." But of this Mr. Spencer feels sure : Na- tionalize the land on righteous principles of compensation, and the interest on the purchase-money would exceed the sum now paid in rent. Moreover, it is a " wild belief " that the land would be better managed — i. e., more profitably managed — by public officials than by private owners. "With a humanity anything like that we now know, the implied reorganization would be dis- astrous." Well, we have only to do with the humanity that we now know; and being what it is, surely Mr. Spencer should have taken pains from the beginning to consider its manifold weak- nesses and temptations. Yet still he repeats that the individual ownership of land was established by force, the assertion that Mr. Laidler and the Labor party of Newcastle stand upon. While, as for his perhapses and possiblies, they are in fact expressions of doubt as to whether the community will or will not resume own- ership of the land, but they are not necessarily to be taken in that sense, and any Mr. Laidler might be forgiven if he saw in them a suggestion of the right thing to do, or a prophecy the fulfillment of which it would not be wrong to precipitate. All the more reasonably might he think so when he sees that in these same revised conclusions Mr. Spencer likens the acquisition of property in land by individuals to the old-time "ownership of man by man." "The ownership of land was established by force"; it originated in robbery ; at the root it is robbery still. That is the point for Mr. Laidler ; and, writing for humanity as we know it, and as the next generation is likely to know it, it is a pity that Mr. Spencer did not guard at once and in the strongest way against the probable use that humanity, as we know it, would make of the assertion. The possible resumption of the land by some totally different generation of humanity, one that we know not of, should not have been committed to print as the righting of a wrong, without the clearest warning that, till that generation comes, land nationalization must be an exceeding great folly, amounting to absolute disaster. For the good of humanity, that 340 THE POPULAR SCIENCE MONTHLY. was always the most important point to insist upon. It is to be feared that some thousands of Laidlers will not think so much of it now. So much does it become political philosophers to be care- ful. Some medicines are also poisons; such medicines should never be issued over the counter to any and every purchaser with- out a warning label ; and this I hope I may say without seeming disrespect for Mr. Herbert Spencer.

To the Editor of " The Times " : Sir : I have read with very great interest the " heckling " of Mr. Morley, the letters of Mr. Spencer and of Mr. Greenwood, and your editorial comments on this triangular duel. But, if I may speak in the name of that not inconsiderable number of persons to whom absolute ethics and a priori politics are alike stumbling- blocks, permit me, borrowing a phrase which a learned judge has immortalized, to say that " You have not helped us much." Let me explain the nature of the further help we require by putting a case which is not altogether imaginary : A score of years ago A. B. bought a piece of land ; he paid the price asked by the vender, and all the conditions required by the law were fulfilled in the transference of ownership. The transac- tion was as much a free contract as if A. B. had gone to market and bought a cabbage. At the time that A. B. handed over his money he believed that the State was a copartner in the contract, in so far that it undertook to maintain his rights of ownership against everything and everybody who should attempt to invade them, except an act of the Legislature, or the orders of the com- manding officer in war-time, or a police officer legally authorized. A. B. has gone on paying his taxes to the State all these years, in full conviction that the State contracted, among other things, to afford him the protection thus defined. A. B.'s lawyers assured him that the title to the land was per- fectly good. This means that, for several centuries at least, neither force nor fraud has intervened, but that the land has passed from owner to owner by free contract. At the same time, A. B., who is somewhat pedantic in the matter of historical accu- racy, admits that, for anything he knows to the contrary, in the reign of King John his bit of land may have belonged to Cedric the Saxon ; and that possibly the son-in-law of that worthy thane, after the quarrel with Rowena, related by an historian of later date than Scott, may have taken forcible possession of it, and, in virtue of his favor at Court, kept it for himself and his de- scendants. LETTERS ON THE LAND QUESTION 341 Now, my friends and myself, having no better guides than common morality and common sense, are of opinion that, suppos- ing Ivanhoe to have behaved in this scandalous fashion, the fact makes not the smallest difference in justice or in equity to the title of A. B. ; and that, if it did, the State, which has contracted to de- fend A. B.'s title without the least reference to such antiquarian contingencies, would commit a gross fraud if it broke its contract on any such flimsy pretenses. The right to compensation is not in question ; what we deny is the right to disturb A. B. on such a ground. It would appear, however, that there is some better guidance than that of common morality and common sense ; " absolute po- litical ethics " is an infallible indicator of what we ought to do — whether the action indicated is possible or impossible. Now, what we want is this very light as to what we ought to do in such a concrete case as that I have mentioned. The dictum that " ownership established by force does not stand on the same footing as ownership established by contract," I must repeat, " does not help us." Construed strictly, it is a mere truism ; con- strued broadly, it may cover Mr. Laidler's view. What we want to know is this : According to " absolute political ethics," has A. B. a moral as well as a legal right to his land or not ? If he has not, how does " absolute political ethics " deduce his title to compensation ? And, if he has, how does " absolute politi- cal ethics " deduce the State's right to disturb him ? No question is raised here as to the right of the State to deal with A. B.'s land or anything else he possesses on grounds of public utility or necessity ; nor do we want to know what may be done by the wisdom or the folly of future generations. " Abso- lute political ethics" should be independent of time and space; and it ought to be able to tell us whether, in foro conscientiw, A. B., if he continue to hold his land under the circumstances sup- posed, is an honest man or a receiver of stolen goods. I intervene in this discussion most unwillingly, but I have long been of opinion that the great political evil of our time is the attempt to sanction popular acts of injustice by antiquarian and speculative arguments. My friend Mr. Spencer is, I am sure, the last person willingly to abet this tendency. But I am afraid that, in spite of all Mr. Spencer's disclaimers, the next time Mr. Morley visits his constitu- ents his pertinacious "heckler" will insist that, after all, the younger and the older philosopher are not disagreed in principle ; and that the difference of " footing " between ownership primarily based on force and other ownership can not be cured by efflux of time, and justifies the State now, or at any future period, in deal- ing differently with the two. 342 THE POPULAR SCIENCE MONTHLY. In Ireland confiscation is justified by the appeal to wrongs in- flicted a century ago ; in England the theorems of " absolute political ethics " are in danger of being employed to make this generation of land-owners responsible for the misdeeds of William the Conqueror and his followers. I am, sir, your obedient servant, T. H. Huxley. November 11th. SIR L. MALLET'S LETTER. To the Editor of " The Times " : Sir : Mr. Frederick Greenwood's letter, and the leading article in " The Times " of to-day, on Mr. Herbert Spencer's recent letter upon this subject, leave little more to be said on several aspects of the question, but there are one or two points upon which I should be glad of an opportunity of adding a few remarks. The passage in the " Political Institutions " quoted by Mr. Herbert Spencer has been long familiar to the students of his writings, and to some of them, who, like myself, are among his sincere admirers, has always been a subject of surprise and regret. The whole extract should be read, but to save your space I confine myself to the concluding sentences, which are enough for my purpose : There is reason to suspect that while private possession of things produced by labor will grow even more definite and sacred than at present, the inhabited area, which can not be produced by labor, will eventually be distinguished a3 some- thing which may not be privately possessed. As the individual, primitively owner of himself, partially or wholly loses ownership of himself during the mili- tant regime, but gradually resumes it as the industrial regime develops; so, possi- bly, the communal proprietorship of land, partially or wholly merged in the ownership of dominant men during evolution of the militant type, will be resumed as the industrial type becomes fully evolved. The analogy here suggested between the ownership of man by other men, or slavery, and the private ownership of land, with the inference drawn from it, that as the first has been abolished in civilized countries the second may possibly share its fate, has always appeared to me essentially fallacious. The principle of private property, so far as the term is appli- cable to human beings, has not in their case been abolished— on the contrary, it has been signally vindicated. The destruction of slavery asserted the right of every man to property in himself, while prohibiting the ownership of man by other men, both individually and collectively. It was the restitu- tion of a right of property from a wrongful to a rightful owner. In order to render Mr. Spencer's analogy applicable, it seems to me that the right of ownership in one man by another, instead of being abolished altogether, should have been transferred, as it is LETTERS ON THE LAND QUESTION. 343 proposed to do in the case of land, from the individual to the State. But, however this may be, it seems clear that the principle which excludes the ownership of one man by another, rests upon the same grounds as that which includes private property in land — viz., that the general interests of society are best promoted by personal freedom. There seems to be sufficient evidence that compulsory labor is less productive than free labor; and if this is so we may con- clude, even setting aside all considerations of humanity or mo- rality, that the interests of society are better promoted by free labor or property in one's self, than by slavery or property in others. This is usually admitted, but it is necessary to insist upon what is always forgotten by those who declaim against private property in land — that this last institution also is an essential condition of personal freedom, as by no other means short of coercion can a due relation be maintained between demand and supply. Whoever holds the land holds that which, being limited in extent (the only assumption on which the question arises), im- poses on its possessor the function and duty, which he is bound in the interest of society, no less than his own, to perform, of restrict- ing an undue pressure on the soil, whether for agricultural or urban purposes, whether for food or shelter, by the increasing wants of the population. If the family is the economic unit, this object may be effected by the exercise of the personal responsibility and authority of its head in regulating supply, and by a gradual augmentation of price and rent in restraining demand. When the limits of pro- duction or supply are reached, any additional population must migrate or be supported, if possible, by charity. But whenever the economic unit is extended so as to include a whole community, this personal responsibility, and with it per- sonal liberty, disappears. In a small district (a village or canton) where the conditions approximate to family or patriarchal life the evil is mitigated ; but in a large and complex society, to vest the property of the soil in the State — i. e., in a central Government, removed, as it must be, from all personal contact with individu- als— is to throw upon it the paramount obligation of either regu- lating the increase of population or of providing food and shelter for increasing numbers by progressive inroads upon the accumu- lated capital of the country — in short, upon the net product, which is the only source of a progressive civilization. The first of these alternatives can not be better described than in the words of Bastiat : 344 THE POPULAR SCIENCE MONTHLY. Ce serait creer le plus faillible, le plus nniversel, le plus immediat, le plus inquisitorial, le plus insupportable, et disons, fort heureusement, le plus impossi- ble, de tous les despotismes que jamais cervelle de pacha ou de mufti ait pu con- cevoir. The second course could only lead to the gradual pauperization and ultimate bankruptcy of any country which had the folly to embark in it. Such an experiment would be only comparable .to that of a vast joint-stock company in which all comers were enti- tled to shares without paying for them. The distinction drawn by Mr. Herbert Spencer, in common with the late Mr. Mill, between private jjroperty in land and pri- vate property in things produced by labor is one which I believe to have no economic justification whatever. It ignores the funda- mental principle, on which the institution of private property is grounded — viz., that a due relation between demand and supply can be maintained in no other way consistently with personal freedom. From this point of view the fact that the supply of land is practically limited, and that it is, therefore, a natural monopoly, renders it not less but more necessary that it should be allowed to be the subject of private appropriation. Sir Henry Maine has summed up the whole question in a few words, which can not be too often repeated : There are two sets of motives, and two only, by which the great bulk of the materials of human subsistence and comfort have hitherto been produced and reproduced. One has led to the cultivation of the Northern States of the Ameri- can Union from the Atlantic to the Pacific ; the other had a considerable share in bringing about the agricultural and industrial progress of the Southern States, and in old days it produced the wonderful prosperity of Peru under the Incas. One system is economical competition, the other consists in the daily task, per- haps fairly and kindly allotted, but enforced by the prison or the scourge. So far as we have any experience to teach us, we are driven to the conclusion that every society of men must adopt one system or the other, or it will pass through penury to starvation.

To the Editor of " The Times " : Sir : As Prof. Huxley admits that his friend A. B.'s title to his plot of land is qualified by the right of the State to dispossess him if it sees well — as, by implication, he admits that all land-owners hold their land subject to the supreme ownership of the State, that is, the community — as he contends that any force or fraud by which land was taken in early days does not affect the titles of LETTERS ON THE LAND QUESTION. 345 existing owners, and a fortiori does not affect the superior title of the community — and as, consequently, he admits that the commu- nity, as supreme owner with a still valid title, may resume posses- sion if it thinks well, he seems to me to leave the question standing very much where it stood ; and since he, as I suppose, agrees with me that any such resumption, should a misjudgment lead to it, ought to be accompanied by due compensation for all artificial value given to land, I do not see in what respect we disagree on the land question. I pass, therefore, to his comments on absolute political ethics. " Your treatment is quite at variance with physiological principles " would probably be the criticism passed by a modern practitioner on the doings of a San- grado, if we suppose one to have survived. " Oh, bother your physiological prin- ciples " might be the reply. " I have got to cure this disease, and my experience tells me that bleeding and frequent draughts of hot water are needed." " Well," would be the rejoinder, " if you do not kill your patient, you will at any rate greatly retard his recovery, as you would probably be aware had you read Prof. Huxley's ' Lessons on Elementary Physiology,' and the more elaborate books on the subject which medical students have to master." This imaginary conversation will sufficiently suggest that, before there can be rational treatment of a disordered state of the bodily functions, there must be a conception of what constitutes their ordered state : knowing what is abnormal implies knowing what is normal. That Prof. Huxley recognizes this truth is, I suppose, proved by the inclusion of physiology in that course of medical education which he advocates. If he says that abandon- ment of the Sangrado treatment was due, not to the teachings of physiology, but to knowledge empirically gained, then I reply that if he expands this statement so as to cover all improvements in medical treatment he suicidally rejects the teaching of physi- ological principles as useless. "Without insisting upon that analogy between a society and an organism which results from the interdependence of parts per- forming different functions — though I believe he recognizes this — I think he will admit that conception of a social state as dis- ordered implies conception of an ordered social state. We may fairly assume that, in these modern days at least, all legislation aims at a better ; and the conception of a better is not possible without conception of a best. If there is rejoicing because certain diseases have been diminished by precautions enforced, the im- plied ideal is a state in which these diseases have been extin- guished. If particular measures are applauded because they have decreased criminality, the implication is that the absence of all crime is a desideratum. Hence, however much a politician may pooh-pooh social ideals, he can not take steps toward bettering the social state without tacitly entertaining them. And though he vol. xxxvi. — 22 346 THE POPULAR SCIENCE MONTHLY. may regard absolute political ethics as an airy vision, he makes bit by bit reference to it in everything he does. I simply differ from him in contending for a consistent and avowed reference, instead of an inconsistent and unacknowledged reference. Even without any such strain on the imagination as may be required to conceive a community consisting entirely of honest and honorable men — even without asking whether there is not a set of definite limits to individual actions which such men would severally insist upon and respect — even without asserting that these limits must, in the nature of things, result when men have severally to carry on their lives in proximity with one another, I should have thought it sufficiently clear that our system of justice, by interdicting murder, assault, theft, libel, etc., recognizes the existence of such limits and the necessity for maintaining them ; and I should have thought it manifest enough that there must exist an elaborate system of limits or restraints on conduct, by conformity to which citizens may co-operate without dissension. Such a system, deduced as it may be from the primary conditions to be fulfilled, is what I mean by absolute political ethics. The complaint of Prof. Huxley that absolute political ethics does not show us what to do in each concrete case seems to be much like the complaint of a medical practitioner who should speak slight- ingly of physiological generalizations because they did not tell him the right dressing for a wound or how best to deal with vari- cose veins. I can not here explain further, but any one who does not understand me may find the matter discussed at length in a chapter on " Absolute and Relative Ethics " contained in the "Data of Ethics." It appears to me somewhat anomalous that Prof. Huxley, who is not simply a biologist but is familiar with science at large, and who must recognize the reign of law on every hand, should tacitly assume that there exists one group of lawless phenomena — social phenomena. For if they are not lawless — if there are any natural laws traceable throughout them, then our aim should be to ascer- tain these and conform to them, well knowing that non-conformity will inevitably bring penalties. Not taking this view, however, it would seem as though Prof. Huxley agrees with the mass of " practical " politicians, who think that every legislative measure is to be decided by estimation of probabilities unguided by a priori conclusions. Well, had they habitually succeeded, one might not wonder that they should habitually ridicule abstract principles ; but the astounding accumulation of failures might have been ex- pected to cause less confidence in empirical methods. Of the 18,110 public acts passed between 20 Henry III and the end of 1872, Mr. Janson, Vice-President of the Law Society, estimates that four fifths have been wholly or partially repealed, and that LETTERS ON THE LAND QUESTION. 347 in the years 1870-'72 there were repealed 3,532 acts, of which 2,759 were totally repealed. Further, I myself found, on examining the books for 1881-'83, that in those years there had been re- pealed 650 acts belonging to the present reign, besides many of preceding reigns. Remembering that acts which are repealed have been doing mischief, which means loss, trouble, pain to great numbers — remembering, thus, the enormous amount of suffering which this helter-skelter legislation has inflicted for generations and for centuries, I think it would be not amiss to ask whether better guidance may not be had, even though it should come from absolute political ethics. I regret that neither space nor health will permit me to discuss any of the questions raised by Sir Louis Mallet. And here, in- deed, I find myself compelled to desist altogether. In so far as I am concerned, the controversy must end with this letter. I am, etc., Herbert Spencer. AniENiEUM Club, November 13th. MR. LAIDLER'S LETTER. To the Editor of " The Times " : Sir : As one of the deputation of members of the Newcastle Labor Electoral Organization who recently waited upon Mr. John Morley, M. P., to ascertain his opinions on certain politi- cal and social topics, I was intrusted by my fellow-members of the deputation with the question of the nationalization of the land, and this subject I discussed with Mr. Morley. In doing so, I sought to back up my position by quoting the ninth chapter of " Social Statics," by Mr. Herbert Spencer, and I certainly thought I had a good case when I found on my side the most distinguished authority of our time. To my great surprise I now find that in the letters which he has addressed to you, Mr. Herbert Spencer appears to be very anxious to repudiate the doctrines which he preached so eloquently in 1850. Now, although it is a common thing for the politician of to - day to repudiate principles and deductions which he formerly warmly espoused and to adopt others which he once energetically condemned, one does not expect the same vacillation on the part of a distinguished phi- losopher like Mr. Herbert Spencer. I find it difficult to under- stand his position, which seems to be this — that while adhering to his general principles he abandons certain deductions there- from. Now, to my mind, the ninth chapter of " Social Statics," which deals with " The right to the use of the earth," seems as true, as logical, and as unanswerable an argument in favor of the nationalization of the land as it doubtless appeared to Mr. Her- bert Spencer on the day it was written. Let us trace the course 348 THE POPULAR SCIENCE MONTHLY. of his argument through, the ten sections of which the chapter is composed : 1. Given a race of beings having little claims to pursue the objects of their desires, and a world into which such beings are similarly born, it unavoidably follows that they have equal rights to the use of this world. Conversely, it is manifest that no one, or part of them, may use the earth in such a way as to prevent the rest from similarly using it. 2. Equity, therefore, does not permit property in land. Other- wise, landless men might equitably be expelled from the earth altogether. 3. We find yet further reason to deny the rectitude of property in land. Violence, fraud, the prerogative of force, the claims of superior cunning, these are the sources to which titles may be traced. Could valid claims thus be constituted ? Hardly. If not, what becomes of the pretensions of all subsequent holders of estates so obtained ? 4. Not only have present land tenures an indefensible origin, but it is impossible to discover any mode in which land can be- come private property. Cultivation can not give a legitimate title. 5. Why not agree to a fair subdivision of the land ? Until we can demonstrate that men born after a certain date should be doomed to slavery, we must consider no such allotment permissible. 6. Either men have a right to make the soil private property or they have not. No compromise is possible. If they have such a right, then the Duke of Sutherland may justifiably banish High- landers to make room for sheep-walks. 7. After all, nobody does implicitly believe in landlordism. If a canal, a railway, or a turnpike road is to be made, we do not scruple to seize just as many acres as may be requisite. If we decide that the claims of individual ownership must give way, then we imply that the right of the nation at large to the soil is supreme. 8. To what does this doctrine, that men are equally entitled to the use of the earth, lead ? Instead of being in the possession of individuals, the country would be held by the great corporate body — society. Instead of leasing his acres from an isolated pro- prietor, the farmer would lease them from the nation. Clearly, on such a system, the earth might be inclosed, occupied, and culti- vated in entire subordination to the law of equal freedom. 9. No doubt great difficulties must attend the resumption, by mankind at large, of their rights to the soil. The question of compensation to existing proprietors is a complicated one — one that perhaps can not be settled in a strictly equitable manner. But there are others besides the landed class to be considered. The rights of the many are in abeyance. To deprive others of TWO AND A HALF PER CENT. 349 their rights to the use of the earth is to commit a crime inferior only in wickedness to the crime of taking away their lives or per- sonal liberties. 10. The right of each man to the nse of the earth, limited only by the like rights of his fellow-men, is immediately deducible from the law of equal freedom. The maintenance of this right necessarily forbids private property in land. The theory of the co-heirship of all men to the soil is consistent with the highest civilization, and, however difficult it may be to embody that the- ory in fact, equity sternly commands it to be done. In the foregoing digest, beyond one or two connecting words, the language is that of Mr. Herbert Spencer himself. Does it not constitute an unanswerable argument in favor of the nationaliza- tion of the land ? If the author would permit it to be reprinted, what an admirable tract the ninth chapter of " Social Statics " would be for the propagation of Socialistic principles ! But he now seems to repudiate the offspring of his own genius ! We have, however, a right to ask that, instead of a vague repudiation in general terms, Mr. Herbert Spencer should tell us specifically what deductions he has abandoned and why he has abandoned them. We might then endeavor to answer his answers to his own propositions. Yours, John Laidler, Bricklayer. -♦*♦- TWO AND A HALF PER CENT. By GEORGE ILES. THE fall in the rate of interest is one of the most striking facts in the financial history of this generation. At times the price of money has risen, and investors have hoped that the good old rates were to be a permanency ; but interest has soon declined again, vibrating about a point a little lower than the center of its former seesaw. Last April, the city of New York, in purchasing certain up- town parks, sold stock bearing 2% per cent per annum, maturing in twenty years, and exempt from city and county taxation. The stock, $7,457,000 in amount, brought on an average 100T3o. High as the credit of the metropolis stands with investors, still higher stands the credit of the United States. Its bonds last April netted a return at current market prices of but 2*07 per cent. During the decade ending with January, 1889, the average rate realized on a United States Government bond was 2'72 per cent ; during the preceding ten years it was 4'06 per cent, very nearly one half more. Comparing the nine years and nine months ending Octo- 35° THE POPULAR SCIENCE MONTHLY. ber 31, 1889, with the decade preceding, the rate of discount charged on prime commercial paper by the banks of New York city de- clined from an average of 6*23 to an average of 5*29 per cent. The Bank of England's rate concurrently compared shows the rela- tively small diminution of from 3*40 to 3'28 per cent.* As far as concerns the manufacturing and trading public who obtain credit at banks in the United States, the decline in the rate of interest has been slight. It has been very different with regard to returns obtainable from investments of the highest class, such as those offered on the bonds of the United States Government, and of the great cities with credit unsmirched by traditions of bankruptcy or repudiation. An investor in a Government bond has certainly a form of property wherein the cares of ownership are brought to the vanishing-point. His security is absolute ; his bonds are registered, so that he need fear no thief ; he can sell all or any part of them at pleasure ; and, should he desire to pledge them for a loan, no operation is simpler and easier. Still, two things remain to be desired — the perpetuity of the obligation, and a larger supply of the securities. In a term of years, all too brief, the bonds will be paid, and the question of reinvestment will come up, perhaps to be settled by heirs and assigns who may be tempted by a shrinking rate of return to accept securities which are no se- curities. Eailroad financiers have noted the demand for perma- nency in investments, and have profited in supplying it.

Investors of the wealthiest class pre- fer investments which, while absolutely secure, may be subscribed for in blocks of a quarter to a round million — a desideratum which further restricts their choice. An electric current may be so in- tense as to become an obstacle in its own path ; a vast volume of capital in the hands of an individual has somewhat the same effect. While the rate of interest on Government bonds, and city and railroad debentures has been steadily falling within the past two decades, the rates payable on real-estate mortgages have declined in sympathy. This year, in New York and Boston, liens on the best city property have been placed at four per cent, two per cent less than the rates current in 1869. In other large cities of the Union a similar decline is observable ; and, as between newly set- tled States and Territories and the financial centers of the nation, the disparity in the rates payable on well-secured loans is much less to-day than it was twenty years ago. The significant point in the matter under consideration is not so much that the rate of interest has been falling as that interest has become distinctly separated from the wages of superintendence and the premium for incurred risk, which used to be combined with it. The return on a Government bond represents the bare remuneration of capital em- ployed, without hazard or care. An investor in first-class city mortgages receives a larger income than if he had bought Govern- ment bonds with his money, but he has not so easy a time of it. He must have titles carefully and responsibly examined ; his credit- ors may be unpunctual ; occasionally he may have the trouble of a foreclosure on his hands. His investments are for comparative- ly short terms of years, and, between one investment and another, part of his capital may be unproductive; or, in reinvesting, he may be obliged to accept a reduced rate. Hence the competition for securities eliminating hazard and bother, which is one of the notable facts in the modern world of finance. Many causes have been at work in bringing down the return on a New York debent- ure to five eighths as much as can be obtained on a Fifth Avenue or Broadway mortgage. First of all, of course, must count the enormous growth of American wealth within recent years ; and, next, the fact that a good deal of it is in the hands of compara- tively few men. A multi-millionaire's income, even at the lowest current percentage, is so much more than his outgo that, if he can be relieved from care and anxiety in looking after his possessions, he is often content to buy securities paying but half as well as the best properties did twenty years since. Another prime cause for the fact under notice is the steady approximation to European rates of interest which has been going on since the close of the 352 THE POPULAR SCIENCE MONTHLY. war. With trade restored to its normal channels, and a steady- reduction in the national debt, have come a constant appreciation in national securities. Ever-improving means of intercourse "by steam and telegraph have brought about a better knowledge in Europe of other leading American investments, and a competition for them which makes the London demand in substantial sympa- thy with that of New York. Meanwhile, too, European rates of interest have fallen ; in 1887 Germany was able to convert her 3|'s into 3's ; last year Great Britain refunded a large portion of her debt, which had borne 3 per cent, at 2f , with a liability for but %\ after a certain term. Among the consequences which have followed the diminution of income from secure European invest- ments has been the invasion of the American industrial field by European capital. This invasion, partly prompted by the fear of continental war, in seeking to add profit to interest, must both tend to increase commercial competition in America and contrib- ute to further lower the rate of interest. A fact recently pre- sented by Mr. M. A. Neymarck, the French economist, is worth mentioning in this connection : when the existing redeemable debts of France, of Paris, and of the French railway companies are paid, the redemption prices will exceed the issue prices by $1,300,000,000. While the progress of science, applied to developing the re- sources of this country, has prodigiously increased its capital, the ratio of it offered for safe investment has increased at the same time. Savings-banks, trust companies, building associations, in- surance companies diverse in type, afford, as it were, a thorough system of conduits to bring every tiny rill of saved earnings to some great reservoir of accumulation. Despite America's increase of population, there are now, probably, fewer hoards of money in its old stockings than ever. When tenders for city, county, State, or railroad bonds are opened, it is usual to find that the majority of competitors are trust companies, savings-banks, and other con- cerns representing small investors, whose demand first and chiefly is that their security shall be unquestionable. To this numerous class a vitally important inquiry is, Are we to expect a rise or a fall in the rate of interest ? In considering this question it will be enough, in passing, to say that abnormal influences affecting the rate of interest are the remote contingencies of foreign war or civil commotion ; the normal influences are chiefly four : First, the comparative efficiency or reproductive power of capital ; next, its security, depending on the character and ability of those who handle it ; third, its supply and demand ; lastly, the soundness of the currency, assuring the repayment of loans in un- depreciated money. With respect to the first factor, a glance is enough to show it to be two-sided. In the new South and new TWO AND A HALF PER CENT. 35 3 West, virgin forests, prairies, and mines offer as splendid oppor- tunities to enterprise as enterprise has ever known ; so far, there- fore, the demand for capital to develop these new resources will tend to raise, or at least to conserve, the rate of interest. While this is true, it must be remembered that a given amount of capi- tal is more efficient now than it ever was, that its efficiency in- creases ; which means lessened demand for it, tending to reduce the terms paid for its use — unless new and profitable applications of capital can be made. As invention after invention is perfected and introduced, the outlay for machinery required to make a million pairs of shoes steadily diminishes. Quick and cheap railroad transportation enables a country merchant to keep his stock at a minimum by constantly " sorting-up " — reducing the capital needed for his business. Telegraphic purchases and pay- ments now exclude the necessity for locking up capital while correspondence goes on through the post-office. In the vast stores of capital, set free in these and similar ways, arrives the opportunity for inventiveness, taste, and skill to create new wants, to supply them and some old wants as well which have long gone hungry — to increase the quantity and improve the quality of life. In so far as such new applications of capital are not commercially reproductive, they tend to maintain the rate of interest. Next, as to security in investment. During recent years there has been an immense growth of American capital in the hands of people unable or unwilling to superintend its application in busi- ness, people in the main desirous of thorough security in their investments — many of them executors and trustees. Financiers have not failed to observe this state of things ; it has enabled them to obtain vast loans at comparatively low and diminishing rates. Of late years have appeared innumerable issues of bonds, debent- ures, and mortgages ; covering not only railroad property, but mills, elevators, apartment - houses, office and club buildings. When the loans obtained by these wholesale borrowings have been remuneratively applied, the result has been all that the lenders could wish. But, unfortunately, the securities which warrant a buyer in dismissing caution and the necessity for dis- crimination are few indeed. The popularity of coupon bonds has extended from those of a substantial description to many of little or no value. During the year ending June 30, 1888, twenty-one per cent of the bonds outstanding on American railroads paid no interest ; the capital involved being no less a sum than eight hun- dred and twenty-seven million dollars. Of allied significance is the fact that in 1888 one in every ninety-eight firms in business in the United States became insolvent. Despite improved methods of transacting business, of estimating credits through mercantile agencies, there persists an overtrading which burdens the com- 354 THE POPULAR SCIENCE MONTHLY. inunity with a heavy tax for bankruptcy. That administrative ability is much rarer than opportunities for its exercise is clearly one of the causes for low interest, and for the addition thereto which bankers and other lenders must charge in order to cover commercial risks. The third influence bearing on the rate of interest is the com- parative scarcity or plentifulness of capital. This is determined not only by the amount and efficiency of capital productively em- ployed, but by the ratio of reproduced capital which is saved. Taking it by and large there seems no reason to believe that hab- its of thrift are losing their hold on the people of this country. As will shortly be seen, the returns of savings-banks bear this out. If persons of small capital are exposed to a reduction of in- terest from the safest forms of investment, this very liability may lead to greater thrift among those of forecasting mind. Where accumulation is quite too small for its income to yield a living, it is the capital sum that is looked to as a resource against a rainy day. Lastly, as to the soundness of the currency. While " the con- sensus of the competent " holds that there is the menace of finan- cial derangement in the legal-tender decision of the Supreme Court of the United States, and in the silver legislation of Con- gress, neither of these seems as yet to have affected the rate of interest. To provide against the contingency of a depreciated currency, whether fiat-paper or silver, now sought to be artifi- cially bolstered in value, certain loans of large amount have re- cently been effected in Wall Street with the express stipulation of payment in gold coin. The precaution is significant. Refraining from any attempt to weigh and balance others of the multifarious influences working for the depression or elevation of the rate of interest, it may be enough to say that the prevailing impression among both economists and men of business is that downward influences will probably continue the stronger in the years of the near future. This means hardship to many worthy people whose time of competence it postpones indefinitely ; hard- ship, too, for the class who, unable to accept business risks or manage business investments, must needs accept less and less re- turn from a little capital. Small comfort for them to hear that prices are falling, so that their loss of income is largely or wholly offset; does not rent rise constantly, and does not the area of " necessities " expand the while with an imperiousness scarcely to be withstood ? But, turning from cases of this kind, which are after all comparatively few, the reduction of the rate of interest paid by secure investments is in the main a benefit ; it means in- crease in the shares of produced wealth divisible as wages and profits, if it also means more for rent. It indicates that the TWO AND A HALF PER CENT. 355 growth of large fortunes is likely to be slower in the future than it has been in the past ; and the growth of large fortunes is in many quarters regarded as a menace to industrial and political freedom. That wages have in the main risen during the past twenty years is clearly shown in the statistics of the State and National Labor Bureaus. In many trades money-wages have advanced ; in others, where they have remained stationary or fallen a little, their purchasing power has increased; in a few trades, superseded by newly devised machinery, and in the case of unskilled labor subjected to competition with hordes of immi- grants accustomed to a low standard of living, wages have fallen below the purchasing power of those paid twenty years ago. No State in the Union adds to her population more immigrants of the wage-depressing type than New York ; still, on July 1, 1889, her savings-banks held on deposit $536,417,974, due 1,389,907 de- positors. The amount had increased $22,000,000 during the pre- ceding twelve months, and $201,000,000 during the preceding nine years. These figures prove a rapid improvement in the condition of the working people of New York ; and, since migration from New York to other States is easy and cheap, her advance in gen- eral prosperity may be fairly interpreted as gauging prosperity throughout the nation. While, then, wages have been rising and interest falling, a new method has perforce entered into the management of large prop- erties. It used to be remarked, as a characteristic of American engineering, that it presented not the best thing, but the lowest- priced thing that would serve. This is true no longer. Every- where we find railroads adopting the most substantial types of construction and equipment. Steel rails long since replaced iron rails ; now steel bridges are replacing wooden bridges ; not only on trunk lines, but on local roads, large outlays are being constantly made for improved curves, gradients and ballasting. Already the increase in the cost of lumber, due to forest destruction, has brought in the experimental use of steel both for ties and for car- construction. A steel tie is dearer than a wooden one, but its life is vastly longer. The same principle obtains in mills and facto- ries : net profit can be increased by a judicious increase of capital expenditure, which adds to the account for interest, but deducts a larger sum from disbursements for maintenance, repairs, and acci- dents. Cheap money for good security has, too, had much to do with the new architecture of our cities — architecture which em- ploys granite instead of sandstone, substitutes sandstone and mar- ble for brick, and demands brick of new durability and beauty. In quite modest dwellings it is now usual to find hot- water or hot- air furnaces instead of the heating stoves still general a decade ago ; ranges and gas-stoves for cook-stoves ; elaborate laundry 356 THE POPULAR SCIENCE MONTHLY. appliances ; electric "bells — all intended to minimize service at the expense of an increased original outlay. If the occupant of a suite in a New York apartment-house, who has abandoned a self-con- tained house, is asked the reason, he will probably say, " I pay just as much rent, but I get along now with fewer servants/' The tendency observable on all hands to provide durability in the stead of flimsiness, the most elaborate and complete machin- ery for anything short of it, is accompanied by another tendency in no sense economical. When banks and office-buildings display floors of rich mosaic, walls and ceilings of variegated marble, stair- cases of Mexican onyx, it is evident that luxury brings a price as well as wholesomeness and commodiousness. Throughout the Union every considerable city has its structures of this type dis- covering the sky, mostly erected by insurance companies who seem to be hedging on the fall in the rate of interest by reaching out after unearned increment. Rent has been affected in diverse ways by the cheapening of secure loans. In so far as mining privileges and the like can be worked with less cost for the hire of capital than ever, their net income, rent or royalty, has increased. Farming lands of all kinds but the best situated or the most fertile have tended to fall in rent as massed capital has become cheaper. Railroads, in opening up vast tracts of new territory with great rapidity, have kept the val- ues of even the best farming land lower than they would otherwise have been. In the same direction also has operated the lowered rate at which money can now be borrowed on farm buildings and machinery. In the cities and larger towns rents have risen remark- ably within twenty years, yet the rise would have been greater still had not the rate of interest dropped. Rent in cities and towns, as elsewhere, depends upon two values — that of land apart from improvements, and that of improvements. The first of these values is determined by the comparative salubrity, publicity, con- venience, and beauty of sites ; other things equal, it will tend to rise as the income of the average citizen rises — with the increase of ability to compete for advantages desired. The rental value of improvements, of all that capital adds in preparing for a build- ing, constructing it, and fitting it up, will tend to approximate to the rate of interest payable on approved real-estate security. In New York city, where land is usually more valuable than the build- ings which cover it, low terms for mortgage interest have not affected rents so much as in smaller cities where buildings are as valuable as or more valuable than their sites. Last spring a block of tenement-houses in New York sold at a price so high as to realize its purchaser but six per cent as a gross return on his investment. If his rents remain unchanged, any further fall in the rate of interest will enhance the price of his property. This TWO AND A HALF PER CENT. 357 incidentally illustrates how as interest falls land values rise, and explains the growing appreciation of home-owning in cities and their suburbs. According to the statistics of the Interstate Commerce Commis- sion, the bonded, share, and floating liabilities of American rail- roads amounted to $8,129,000,000 on June 30, 1888.* It is not likely that science has any such revolutionary gift for mankind in the near future as the railroad ; and as American capital at this time demands new outlets whereby to effect new economies or save noteworthy waste, it may be allowable to note some fields for sound investment as yet unoccupied. Is not the improvement of our towns and cities, as such, a field which capital might well enter ? Recent investigations by Captain Francis V. Greene, of New York, and other experts, demonstrate that, were the city's pavements as good as they should be, horses could draw threefold greater loads over them, with an immense abatement of both noise and filth. While the improvement of the metropolis due to individ- ual enterprise and taste has been marvelous of late years, its man- sions and business structures vying with the finest in the world, the city as a city is little changed. Its gas, water, and sewer pipes are still laid in the earth beneath its streets, subject to unceasing disturbance for repairs. Its electric wires, for many years a griev- ous eyesore, a menace to pedestrians and an obstruction often fatal to its firemen, at last have so multiplied in number and deadliness that a beginning has been made in laying them underground — a tentative procedure attended with all the uncomfortable results of an underground piping for gas and water service. Repeatedly the suggestion has been made, echoed at last in the City Hall, that subways be constructed for the accessible disposition of gas, water, and sewer pipes, and for electric wires. Never until this sugges- tion is acted upon will the city's pavements be free from constant breaks, which, were repair of the carefullest, would never permit New York streets to remain smooth and seemly. Subways of the kind proposed could easily accommodate pneumatic tubes for the conveyance of postal letters and parcels. To-day the mails trav- erse New York, much as furniture and vegetables do, in common vans. So slow is their delivery that letters from Albany, arriving at the Grand Central Station at 7 A. M., reach Fourth Avenue and Thirty-second Street partly at 10.40 a. m., but in larger part be- tween 12.40 and 1.10 p. m. The point named is half a mile from the station, on the way between it and the Post-Office. The quickest train from Albany to New York travels the distance, one hundred and forty-eight miles, in three hours and thirty minutes ; a letter traversing a distance of six miles within the city occupies * Of this stupendous total, 39 per cent had made no return whatever during the preced- ing twelve months. 358 THE POPULAR SCIENCE MONTHLY. on an average five hours. Long ago the Western Union Tele- graph Company connected its Madison Square branch with its headquarters on Dey Street : written messages are transmitted through its cylinders, two and a half inches in diameter, at the rate of a mile a minute. The tube in its course connects with three branch offices in Broadway — a hint for the pneumatic con- nection of branch post-offices with the general Post-Office, which, extended to the principal railway stations and ferry-houses in the metropolitan district, would give the postal service a new effi- ciency. More important than this pneumatic tubing is the ques- tion of rapid passenger transit, the inadequacy of existing methods being peculiarly impressive as the great exhibition of 1892 is dis- cussed. Whether by tunnel or viaduct, it seems imperative that New York, at an early day, shall provide itself with transit facili- ties such as those of the German capital, where trains stopping at all stations, and trains running at high speed stopping only at the principal stations, run on separate sets of tracks. This continent is, after all, only a larger kind of island, and in- crease of transatlantic travel has been needed to remove some of its insular complacencies, especially that with which it has hith- erto regarded the condition of its streets. In common with New York, every city and large town in America requires what may be called integration — a thoroughly comprehensive and intelligently planned outlay of capital for every means of welding it into a unit — commodious, wholesome, and pleasant to live in ; easy and cheap to get about in. There is an art of city design as well as house design : modern house plan- ning not only bestows new comforts and refinements, it makes them all part and parcel of a whole. When cities and towns are treated structurally exactly as a good architect treats the edifice an unstinting capitalist asks him to create, life in them will be much better worth having than it is. And the financial oppor- tunity to do all this appears when New York can borrow money at two and a half per cent — a rate one half as much as her citizens are obliged to pay for individual borrowings. What has been said with regard to cities and towns applies equally to means of communication between them and villages — the common roads, whose badness Prof. Shaler tells us imposes a tax of at least ten dollars a year on the average American household. Road im- provement offers scope and verge for the profitable and safe in- vestment of a good many millions now idle. Passing from matters of municipal and county administration to State and national interests, does not cheap and abundant capital make it possible to conserve the Adirondacks as a State park, and as the source of the principal rivers of New York ; to establish a national system of afforestation ; to reclaim the arid plains of the THE RARE FORMS OF ORCHIDS. 359 far "West to fertility ; to take in hand on "broad lines the improve- ment of the nation's water-ways ? Governments, honest and able, can do many things for the common interest which the people as individuals are powerless to do for themselves. Honest and able, there's the rub ! The municipal administration of Berlin, a city well-nigh perfect in government, is carried on for a trifle more than the interest on the public debt of New York. Abounding cause is there to fear waste, corruption, and incapacity in any extension of governmental functions which the future may de- velop. Still, it is not so much fear of this kind which prevents that extension, as a lack of perception by the American people, governing and governed, of the great benefits that can follow the organized action of municipalities, counties, States, and the nation itself. There is much deploring of political degradation and political immorality: may we not reckon in the future, among the forces working for reform, that of capital wrongly excluded from vast fields of usefulness and profit ? ♦•♦ THE RARE FORMS OF ORCHIDS. By J. DYBOWSKI. THE varieties of plants which, under various titles, charm us as house-ornaments, and give our habitations a character of freshness and life that is always dear to us, are already numerous. Right along with their growing number goes our increasing affection for them. They are not of the kind of things we tire of as soon as we become acquainted with them ; but the more inti- mately we know them the more disposed we are to seek for new ones. They will never become common. We might suppose that, the more numerous rare flowers become and the more fond ama- teurs grow of them, common flowers would fall into neglect. But this is not so. We are not only fond of flowers because they are rare or precious, but we love them also for themselves and for the attractions of their own that they possess. In the grand army of flowers which seem made to impress a tone of the gay on the sober background of our existence, there are some stately ones that appear to constitute a kind of aristocracy of this enchanting world. Such flowers are the subject of our present essay. The orchids, conquerors of the light, may well claim pardon for their triumph over their humble companions of the gardens, for their victory is fairly achieved. They astonish us when we first exam- ine them, then charm us. Nature has been liberal with them, and they have everything. Their flowers are full of that curious 360 THE POPULAR SCIENCE MONTHLY. charm that captivates. Their colors are harmoniously toned, and always bright and elegant. Their odor is sweet and penetrating, but does not cloy. Notwithstanding their thin texture, which gives them a delicate and frail air, they last longer than other ornamental flowers. Nothing, in fact, seems to be wanting to them but a more lively and abundant foliage ; and that can be supplied by mingling fern-leaves with them. It was long supposed that these wonderful plants were ex- tremely delicate and capricious. This was a mistake. To their other virtues they join the rare one of simplicity. Nearly all the orchids cultivated in greenhouses are natives of the intertropical zone, and it was supposed from this fact that they required considerable heat. But it has gradually been es- tablished that a high temperature really hinders their best devel- opment. A considerable number of them in their native state grow on high mountains, under exposure to a bracing atmos- phere ; and they are now cultivated in moderately warmed and freely ventilated greenhouses. They are therefore relatively hardy plants, well adapted to the decoration of our rooms. The genera and species of orchids already known are very nu- merous, but the varieties are more so. The cause of the multiplic- ity of form, shade, and appearance lies chiefly in the organization of the flower. Without going into technical details and descrip- tions, it is enough to say that the pollen is not spontaneously carried to the stigma, and that a foreign agent has to intervene in the fertilization of the seed. The office is discharged by insects, which visit the flowers for their honey and involuntarily load themselves with pollen ; then, flying from one flower to another of different varieties and species, they effect all kinds of mixtures. Consequently, varieties are endlessly multiplied. While many of these may be common, others obtain special hues or streaks, which render them rare and cause them to be sought out by collectors. Now that orchids are in full favor, and are likely to continue so for a long time, enormous prices are paid for the choice varieties. A Catileya (Fig. 1), shown at a recent horticultural exhibition in Paris, had a light violet-blue corolla instead of the usual rose- violet. This sport in color was enough to raise the price of the plant to ten thousand or twelve thousand francs. The owner — M. Piret, of Argenteuil — had himself sought out the variety in the forests of Venezuela. The instance is not a rare one. At a recent sale in Ghent, every specimen of a certain Cypripedium brought six thousand francs ; and like prices are often obtained in England. The ordinary prices in trade are, however, more moderate than this. As the result of numerous explorations, often made at great risk of life, orchids of all kinds and of the more usual varieties have been imported by thousands within the last THE RARE FORMS OF ORCHIDS. 361 few years, and are sold at reasonable prices ; and the business of dealing in them returns little profit unless some of the rarer vari- eties are on the list. While it is difficult and dangerous to go to their native haunts for orchids, it is not much more easy to possess the rarer varieties in cultivation; for, while the care of adult plants is compara- Fig. 1.— Orchids, Caitleya nossia (bluish mauve). tively easy, the raising of the seedlings is attended for many years with almost insurmountable difficulties. But cultivators have become possessed with the idea that it would be well to imitate with species selected for their beauty and good forms the acci- dental hybridizations of the forests. Many have tried ; a few have succeeded. One of the first among these was M. Bleu, General Sec- retary of the French Horticultural Society. He cross-fertilized, sowed the seeds, and raised young plants. To appreciate the diffi- culties of these operations, they must be followed out. In the first place, the seeds are so fine that they can not be seen without a strong glass ; they are sown on the bark of trees or in chopped moss ; and they are transplanted when the plants are so small that the work has to be done by the aid of a magnifier. These material difficulties are still as nothing compared with the care that has to be given the nurslings to secure a good development of them. The cultivator may consider himself fortunate if he gets a few dozen good plants out of several thousand seedlings. Orchids in all their varieties of aspect and form have very dif- vol. xxxvi. — 23 362 THE POPULAR SCIENCE MONTHLY. ferent ways of growing. Some, like the lady's-slippers (Cypri- pedium) and the superb Odontoglossums, are ground-plants ; oth- ers, perhaps most of the class, are epiphytes, attaching themselves to the bark of trees, where they live at considerable heights above the soil. Of this class are the fragrant Cattleya and the splendid Plialcenopsis, so elegant with great bunches of white or rose- colored flowers. It follows from this great diversity of exigencies that orchids lend themselves readily to all possible combinations in the orna- mentation of rooms. Some are cultivated in pots and help in the decoration of jardineres (Fig. 2); others, which live on the trunks ^4 mrf- t**~\ ^a&^i8 _ :s Pig. 2.— Orchid-Growing in a Room.

Orchids will last a long time in a room if proper care has been taken in cutting and transporting them. The flower will some- times keep its freshness for two or three weeks. Their preserva- tion may be prolonged by covering them every evening with a sheet of silk paper, which will protect them from dust and excess- ive evaporation. They lend themselves remarkably well to the formation of bouquets, where their quality of keeping fresh for weeks gives them much value. An effective bouquet shown at a horticultural exhibition in Paris, which was formed by attach- ing orchids mingled with branches of asparagus to moss-covered bamboo sticks, is shown in Fig. 4. On account of their enduring freshness orchids are favorite flowers for bouquets to be worn on THE RARE FORMS OF ORCHIDS. 363 ^B0. festive occasions, and a considerable trade has been developed in flowers for such uses. Favorite kinds for this purpose are the Odo ntoglossums, with handsome white, starry flowers, and the Oncidium papil- io, with its but- terfly-shaped co- rolla. The enormous sums that are often paid for or- chids are decried as foolish, and the extravagance is sometimes com- pared with the craze that once raged about tu- lips. The two fashions are not to be compared ; for there is some- thing real and solid about or- chids, which will always give them rank among the finest and most highly esteemed flowers ; while tu- lips are not fine, and soon suffered a loss of the ex- travagant admi- Fig. 4.— Motive in Cut Orchids, mounted on Bamboo. ration that prevailed for them for a time. New varieties of the rose, although it is a very old flower, still bring higher prices than the rarest of orchids. — Translated for the Popular Science Monthly from La Nature. One point of great interest observed by Dr. Hansen in his expedition across Greenland was the very low temperature in the interior, which seems to be in de- parture from the received meteorological laws. This may, he thinks, throw a good deal of light on the much-discussed question of the cause of the great cold of the Glacial period. No better place can be found for the pursuit of this inquiry than Greenland. 364 THE POPULAR SCIENCE MONTHLY. IRRIGATION OF ARID LANDS. By HENRY J. PH1LP0TT. THERE is no more striking difference between the inhabitants of the Eastern and Western United States than the degree of their familiarity with the word irrigation. And there will never be a profounder difference than will be engendered by the thing itself. The Eastern farmer irrigates his cabbage and tomato plants when he first transplants them. His wife irrigates her flowers. The city gentleman irrigates his lawn. But the idea of watering a whole farm — not a New England "patch," but a Western ranch of from fifty to fifty thousand acres — seems a financial absurdity. What the Eastern farmer could not produce without such expensive cultivation he would say was not worth producing. Equally incredible will seem farming without irrigation to the generation now growing to manhood over a large part of the Pacific coast. To them it will seem an absurdity not to have the water as fully under your own control as the land. They would not want to cultivate land if they had to take chances on there being neither too much nor too little rain. What would surprise the Eastern farmer still more, if he knew it, is that thousands of acres of land, intended for nothing but hay and pasture, are not only irrigated from ditches a dozen miles long, but must first be leveled down with road-scrapers, and often the grading costs twenty-five dollars an acre. This, however, ap- plies only to certain forms of irrigation. My present purpose is to describe a number of different ways of irrigation which I have seen exemplified on a large scale. The simplest plan is with a street-sprinkler. It is profitable on certain crops of high value per acre. For irrigating trees and vines the spray may be taken off the wagon and a straight stream conveyed by a short hose to the roots. I have seen vineyards of one hundred acres watered in this way. It is chiefly used in tid- ing young vineyards and orchards over the first year, on land which thereafter will need no irrigation. It always struck me rather comically to see a street-sprinkler meandering over a field thirty miles from the nearest town, as if it had got lost and were groping about and trying to find its way back to its native haunts. In such case the original source of the water may be a well or a mountain canon. I confess it still staggers me to see the miles of iron pipe through which a stream of irrigating water must often be carried from the mountain spring to the nearest field whereon it is to be used. A two-inch pipe, by the time it is laid, IRRIGATION OF ARID LANDS. 365 costs anywhere in the neighborhood of one thousand dollars a mile. Wherever the water comes from, it is usually conveyed into a tank or a reservoir, and then piped or ditched about over the farm wherever needed. A hand pump is a rarity in southern Cali- fornia. A windmill pumps the water into a high tank, which gives it the pressure needed for sprinkling. Hydrants are placed at the house, at the barn, in the garden, in the orchard, and at other points. With plenty of hose the fire protection is admi- rable. The farmer's wife is as well off as her city cousin in the matter of water conveniences. Running through iron pipes near the surface of a blistering hot soil, the water gets warm, not to say hot, and so it does stand- ing in the tank over the well. When wanted for drinking, it is put into a porous earthen jar called an alia, and the evaporation of the large part which soaks through the jar cools the contents. Always in the morning, and nearly always throughout the day, you can get a drink as cool as the stomach ought to have. Some- times a barrel, covered with a cloth kept wet, is used for the same purpose. The water thus piped to various points on the farm is some- times carried from the hydrants through ditches which run along the highest parts of the ground. These ditches are the simplest possible in construction. They go winding about like natural streams. Sometimes a furrow of the large farm-plow answers every purpose. For the capillaries of the circulation the furrows made between the rows of vegetables in cultivating them are quite sufficient. When you have irrigated a few rows, a hoeful or two of earth applied to each furrow stops the water from them, and then the dam is removed farther down the main stream, and more rows are irrigated in the same way. The method of irrigating trees is different. A circular de- pression, with a raised rim, is made about the tree. In a large orange orchard this is done with a machine — a kind of compli- cated scraper dragged around each tree by horses. The saucer thus formed may be fifteen or twenty feet, but is usually much less, in diameter. The water is turned into it from a hose or through a surface ditch. An orange grove never looks prettier than when thus prepared for irrigation. Sometimes, instead of the circular basin about each tree, small ridges are thrown up midway between the rows, in both directions. This makes a larger irrigated surface, and, of course, requires more water. All these methods of irrigation are simply extensions of ordi- nary garden watering. I have seen two other quite different methods in operation. One of them is the simplest and cheapest, the other the most complicated and expensive of all. 3 66 THE POPULAR SCIENCE MONTHLY. In the former nothing is done except to dig a large ditch through the field, as near the middle as is consistent with its fol- lowing sufficiently high ground, or between two fields, if both are to be watered from it. Through this ditch, or zanje, a slow stream of water is kept running. It soaks into the ground and percolates or " seeps " through it and thus sub-irrigates the whole field without any lateral ditches. Of course, this occurs only in peculiar soils. Its best exemplification is in Fresno and Tulare Counties, California. Sometimes a single ditch, nearly straight, will in this way irrigate one hundred and sixty acres. The other method is exactly opposite. The whole field is flooded. Head-gates are placed along the main ditch, and from every head-gate a dike or levee is run across the field. Levees are also run along the sides, one of them forming the outside of the ditch. If these levees ran at right angles, a field thus pre- pared for irrigation would look for all the world like a huge printer's case. The levees may be two to four feet high. The intervening spaces are called " checks," and may contain any amount of land. I have seen one thousand acres cut into checks of from one to ten or twenty acres. I did not see how it could pay. Nothing was grown but hay and pasturage. The checks are leveled, if not already sufficiently level. They are flooded one at a time. In flooding check No. 1, head-gate No. 1 is opened and No. 2 closed. As soon as the whole surface of this check has been covered with water, head-gate No. 2 is opened, and the same flood runs back into the ditch and down into check No. 2, and so on. The water is kept on the land but a short time. In warm weather the flooding is done mostly at night. The basins or checks formed by the dikes are not filled with water. Alfalfa hay is cut four or five times a year, and the land is flooded after each cutting. Twelve tons a year per acre are not a rare crop, though less is commoner than more. For wheat and other cereals one good flooding is enough. A good deal of California land has been over-irrigated. Al- kali has been brought on or brought up, the soil has been made heavy, pools have been formed from the " seepage," and orchards and vineyards have been spoiled. After a field has been irrigated for a few years it becomes saturated, and wells dug in it soon reach water. It no longer needs so much water, and its former supply may be carried on to reclaim new deserts. How much a single river will reclaim, only give it time enough, can be vaguely guessed. Thousands of acres in the San Joaquin Valley have been placed beyond the need of further irrigation. The whole valley was once a desert. A part of it seems beyond the reach of any irrigation except IRRIGATION OF ARID LANDS. 367 what can be done during the rainy season. The Coast Mountains do not furnish living streams, and the Sierra Nevada water must run up hill to cross the valley and climb the western slope. How to get it over there is a problem vexing many minds. Several companies have been formed, and surveys have been made, for doing the work on different plans. One company proposes to lay iron pipes about fifty miles, at a cost of several millions of dollars. Another would carry the water in an open ditch above ground. At the lowest part of the valley-trough the ditch would have to be at least fifty and ought to be at least one hundred feet above ground, for several miles. Under a new law of California, irrigation districts may be formed, and a vote taken as to what, if any, mains shall be con- structed. A majority of residents rules. The minority, if they own land, help foot the bill. So do all non-resident land-owners. The district where these great iron pipes aforesaid are proposed would contain about eight hundred thousand acres. It was esti- mated that five dollars an acre would pay the cost. A gentle- man interested as a landholder, however, assured me that his honest estimate would be not less than two hundred dollars an acre. With plenty of water the land, now practically worthless, would be well worth one hundred dollars an acre. It will be readily admitted that such gigantic schemes of irri- gation as these must raise new questions of both civil law and political economy. The constitutional conventions of the newly admitted States spent some time in wrestling with the problem of water rights. In all our arid regions property in land involves property in water. If by going higher up the river or canon your neighbor may divert and use the water you have depended on, he might as well be permitted to take your land also, for it is valueless without the water. Litigation over these water rights has already given the California courts much to do, at heavy ex- pense to litigants. The rights themselves vary. In some cases one man or corpo- ration owns the water, while another merely has the perpetual right to a share of it on the payment of a reasonable rate. But this right pertains to a particular body of land, and not to the person. In other cases each landholder is a shareholder in the water company. The difference appears on the face of the stock certificate. In the former case the name of the association which has tapped, say, the Alpine Canon, will be " Alpine Water Com- pany," while in the latter case it will be " Alpine Land and Water Company." There are a good many of these land and water companies com- posed of farmers. Here is a new element introduced into farm life — an element of business and of co-operation. Sometimes it 368 THE POPULAR SCIENCE MONTHLY. involves also an element of clannishness ; as, when two such com- panies fall to fighting over the same supply of water. In fact, as I have already observed, this necessity of irrigation will make the deepest of all the differences in personal character and habits of thought between the East and the West. Nobody will doubt that the institution of property in land has an important influence on character. Why not, then, property in water ? And while this may be said to exist in the East, it is rarely thought of, while in the far West it is the thing most thought of and talked about. It is the main factor in human sustenance. The result is bound to be that East and West will take differ- ent views of life. Hence they are likely not to understand each other. At present this makes the less trouble, from the fact that the East can so easily outvote the West. I mean, of course, the arid West. I think it a safe proposition that, when the country is all settled to a density everywhere corresponding with its fer- tility, the arid lands will outvote the regions needing no irriga- tion. And long before that time they will hold the balance of power. Already the irrigants have secured from the non-irrigants the concession of an appropriation for surveys, and the appointment of a senatorial committee, which is now on its travels, studying the advisability of a great system of irrigating reservoirs to be built, or at least surveyed, at national expense ; and in the latter case the demand will doubtless be for such disposal of the affected public lands as will make it worth some private citizens' while to construct the reservoirs. The desert-land act was intended to be a step in that direction. Under that law, the man who irrigates a square mile (six hundred and forty acres) of desert land within three years after filing his entry, may buy it at one dollar and twenty-five cents an acre. It must be land not capable of producing crops without irrigat- ing, and twenty-five cents per acre must be paid at the date of entry. By the operation of this law, and by purchase of adjoin- ing railroad lands, a single firm has acquired the ownership of four hundred thousand acres of as good land as ever lay out of doors. The owners have carried over it the most gigantic system of irrigation on this continent. They have divided up the waters of Kern River, and spread them out into a great artificial delta. They have now begun to sell their lands in small lots of ten, twenty, forty acres, and so on. I attended one of their auction- sales, and saw land, which ten years ago was uninhabitable desert, knocked down at fifty, a hundred, and even a hundred and fifty dollars an acre. The water rate is extra, and is so much per inch used. An inch is the amount that will run through an orifice an inch square in the course of a year, under a four-inch pressure. IRRIGATION OF ARID LANDS. 369 The desert-land act was not intended to pnt snch large bodies of land in the possession of so few men. But any law is apt to work that way. Where the stock of the water company is held by all the land-owners using, the land is often hypothecated as security for the assessments, and in default of payment could only fall into the company's hands. What sort of land monopoly will grow up under it, the whole business of irrigation is too new to foreshadow. There is a bitter feeling already against certain large owners and syndicates. But it is doubtful whether the still heavier enterprises of damming waters up in the caiions will ever be carried out by private purses, unless those who go into them are well assured of fee simple in still larger bodies of land. And that, I judge, is about what far Western people mean when they say they don't want the Government to dam the waters, but only to " encourage private enterprise." The landscape effects of some of these irrigating systems are quite striking; sometimes pretty and sometimes depressing. Many of the main ditches are fifty feet wide. Such a stream of water, or a much narrower one, must form no insignificant part of the picture on the eye of the traveler. If it is straight, slug- gish, green, bare, it may be a nightmare in its oppressive ugli- ness. But where it winds about like a natural stream, as it often does in order to keep on high ground, and is shaded by trees planted hap-hazard along its banks, it is a thing of beauty. You drive along a lovely lane, lined on both sides by tall pop- lar-trees, between fertile fields, gardens, orchards, shady groves, and now and then you come to one of these artificial brooks. You may have to go up hill to cross it. In fact, the sides of the ditch are naturally and properly above the level, so that the water will run out over the land. So you have the funny sensation of crossing a creek on a hill-top, and even then driving upward to get over it. The bridge is natural as life, and likewise the mill- dam and the mill. A drive through the country between Han- ford and Fernone is as pretty as the imagination can picture it. Its beauties are wholly artificial. Ten years ago that was a desert ; to-day it is ahead of the Mohawk Valley in everything that goes to make a fine-looking agricultural region. Its one fault as a landscape is that it is as level as a billiard-table. It is a disputed question whether irrigation induces disease. Certain it is that the irrigated portions of the San Joaquin Valley are malarious. But Mr. Nordhoff says they are less so than before they were irrigated. I have talked with some hundreds of the inhabitants, and they seem as a rule to think otherwise. They do say, however, that there is an improvement in the general health since they learned to drink deep-well water instead of the surface water which seeps through from the ditches. Some neighbor- 37o THE POPULAR SCIENCE MONTHLY. hoods have artesian water. The whole valley is hot as a furnace, and the steaming canals probably make it seem hotter than it would, and may breed malaria as well as frogs and mosquitoes. The Secretary of the Interior is reported to have sent an agent to Europe to study the subject of irrigation. We have a corps of engineers and a senatorial committee studying it in America. On the whole, it looks as if we ought to find out something about it. I have made a special study of it, and find it quite interest- ing. There is, perhaps, no more striking application of science to agriculture. You must know how to compute the mass of water that will flow through a ditch of a given size with a given fall. You must also know how much water will irrigate your particu- lar piece of land. This will depend on its character as well as its size, and also on its annual rainfall. It is astonishing how much the commonest Calif ornians know about rainfall records. Rain-gauges are kept everywhere. The morning after a shower the farmers, instead of merely informing one another that it has rained, fall to talking of the quantity — and there is a good deal of sense in that. " My gauge showed fifty-seven hundredths of an inch," says Farmer Jones. "That makes 11*24 inches we have had this season," says Farmer Brown ; " last season up to this time we had 13"42." And then they dis- course of the precipitation yet needed to produce a crop without irrigation, or with partial irrigation, and the amount of irrigat- ing water that will be required. The morning paper will give the rainfall in hundredths of an inch for a number of points throughout the coast country. The size and strength of dams, head-gates, levees, etc., are mat- ters requiring mathematical calculation of a delicate kind. Johns- town tells with terrible earnestness how important it is that these calculations should be to the last degree accurate. A careful sur- vey of the route of each important ditch is also necessary. In fact, a number of sciences are involved in irrigating, but " prac- tice makes perfect." Little by little the Western farmers are learning to depend more on cultivation and less on irrigation. They find it better in many ways ; they now irrigate a greater area with the same amount of water. This hastens the day when the much-talked-of storage will pay. What ought the Government to do in the premises ? Tax the East to dam the West ? I should say not, unless the expense were recouped. Perhaps it might construct the works and increase its prices on the land benefited. It gives lands to railroads in alter- nate sections, and then gets even by doubling the price of its own lands. What sort of a plan would it be for Uncle Sam to follow the example of the land-operators above mentioned — irrigate his land and sell it off at auction ? He might sell it on sealed bids. PALM-TREES AND THEIR USES. 3?l I should not much, wonder if he could in this way make a hand- some speculation. Since the above was written, I read in the dailies that Secre- tary Noble has been informed that speculators are following in the wake of the Government surveyors, and trying to secure land and water titles ; and that the Land-Office has been instructed to inform its registers and receivers throughout the arid regions that no such business will be allowed, but that the Government will retain control of these rights. This is a matter of several hundred times more importance than one Eastern man in a dozen will dream of. -+*+- PALM-TREES AND THEIR USES. By M. J. POISSON. AFTER the grasses, with their various adaptabilities for the purposes of food and the arts, the palm-trees hold the first place ; and this, not only on account of the uses for which they are fit, but also by reason of the beauty and amplitude of their foliage and the stately size which many of them attain. Their worth in decoration and their usefulness have been celebrated in all times and in many languages. In the time of Linnaeus, eight or ten species, belonging to half a dozen genera, were known. At this time the number of determined species exceeds a thousand, and these are distributed among about one hundred and thirty genera. In a short article like this we can only touch upon the subject and indicate the principal useful species. The date palm was the one of most interest to the ancients. It is the fortune of the peoples of northern Africa and the orna- ment of the oases of that region. It sports into numerous varie- ties, which are easily obtained from the seed. When quarrels arise between tribes, the first thought of the hostile factions is to ruin their enemies by attacking their date crops. The male and female flowers being borne on different trees, a few male plants are sufficient for the fecundation of a great many females ; and the destruction of the former — not a very hard task — will make the latter worthless. Date-trees the fruits of which are not pala- table are used for building purposes, or for making palm-wine — the fermented sap, which is drawn from the tree by tapping it as we tap maple-trees. The sap is also much drunk fresh, when the Arabs call it lagmi. The dates are eaten directly, or their ex- pressed juice is used for sirups and flavorings. Those which, because of being grown too near the sea or in unfavorable situa- tions, as at many places in the regency of Tunis, do not become fully ripe, are mixed with bread and fed to horses and cattle. 372 THE POPULAR SCIENCE MONTHLY. The dwarf palm of Algeria and southern Spain (Chamcerops humilis) is not a profitable sort, but is rather a detriment to the Algerian plains. When it gets possession of a spot, it is very hard to exterminate, and the place becomes little to be preferred to the desert. The palm lands have, however, been cleared to a considerable extent since the French occupation of Algeria. The leaves are used in making brooms, baskets, and minor articles, for paper pulp, cords, and " vegetable hair." The tender, plump buds of many species of Indian and Ameri- can palms supply a choice food which is called " palm cabbage." The young tissue, which is very like salad-heart, is eaten raw or cooked and seasoned in different ways, or pickled. The leaves that are large enough are used on the roofs of houses or in the manufacture of a diversity of articles. Hindu characters are sometimes traced with a bodkin on strips of the leaves of the fan palm (Corypha) of the Indian islands, and these are folded like letters and sent in the mail. The flexibility of the leaves adapts them to many purposes of art. From the young leaves of the coco (Lodoicea seychellarum), whose enormous and strange-look- ing fruit is an object of curious interest, the natives of the Sey- chelles Islands make some handsome basket-work. The extremely light and durable hats called Panama are made from the leaves of species of this family. The pellicle of the leaves of the Baphia, or sago palm of Madagascar, from which the natives of that island make fine cloths, is used for ties in gardening and in the manu- facture of artificial flowers, and is good for many other purposes. Bridges over torrents and small rivers are made of the solid trunks of palm-trees. When the wood is fine and close, it is split into pieces that are turned and polished. Highly esteemed um- brella-handles — called laurel handles — are made from several kinds. If the central part of the stem is filled with tender pith, not too much stringy and tough, it is collected as sago ; of which the sago palm of Madagascar and the corresponding regions of Africa affords the most highly prized quality. Stems of small diameter are equally desirable. The jungles in the East Indian Archipelago — Java, Sumatra, and the peninsula of Malacca — abound in climbing palms or palm vines, the stems of which wind among the limbs of the trees to the top. Some have been measured that were a hundred yards long before they became interlocked with the network of the forest. They are the rattans (Fig. 4) which are so handy where a cane or any kind of flexible stick is wanted. Chairs are caned with the outer part of the rattan, and from the rest of the stem children's chairs, baskets, and many useful articles — including even dish-cloths — are made. The author of this essay has had considerable success in making such ornamental articles as earrings, scarf-pins, etc., out of the PALM-TREES AND THEIR USES. 373 handsome fruits of some of the rattans.

The most famous 374 THE POPULAR SCIENCE MONTHLY. Fig. 5. — Oham^erops excelsa. of these is probably the Areng, or sugar palm of Amboyna {Arenga sacchar If 'era), which grows in India and the archipelago. It is a superb tree, with pinnate leaves twenty-five feet long, and is as handsome as it is useful. A number of species be- longing to different genera furnish a kind of hair of finer or coarser texture. It is found in the fibrous sheaths of the leaf-stalks and in the jagged edges of the leaves. Cables made of the black, tough fibers of the Areng are preferred by the coasting sailors of the Spanish colonies on ac- count of their elasticity and durability ; and they are, moreover, very fine. The hemp palm of Japan and China {Chamcerops excelsa, Fig. 5) is available in the hands of the industrious people of those countries for making the finer brooms, light strings, and a thousand articles of daily use. Palms of coarser fiber, like the Piacaba of Brazil (Leopoldina piacaba), furnish material for blinds, brushes, brooms, and the rollers of mechanical sweepers, which are much more durable than rollers fitted with steel teeth. A waxy exudation forms on the trunks of the wax palm of the Andes (Ceroxylon andicola) and is collected by the natives for purposes of illumination. The Carnauba of Brazil (Copernica cerifera) forms a cerous efflorescence on the inside of its leaves. The natives climb upon the trees of the latter species and beat the leaves with rods, when a fine snow falls from them and is col- lected on cloths spread upon the ground for the purpose. The wax of the Carnauba is used in commerce, both by itself and asso- ciated with other similar substances. The fruits of the palm are inferior to none. Every child knows what Robinson Crusoe did with his cocoanuts. After dates, this is the most generally diffused fruit of the palm. No drink is more in demand among the Creoles and blacks than the milky kernel of the green cocoanut. When the fruits reach us, the albumen has hardened and become somewhat tough and indigestible. This nut is one of the sources of wealth — in some cases, perhaps, the only one — of the coral islands of Oceania and some other tropical regions. With the top in the sun and its roots bathed by the sea- waters — its favorite station — the cocoa-tree (Cocos nucifera) con- tinues in good condition to the age of seven or eight hundred years. The dry nut, called copra, is marketed by the thousand tons every year, to be employed in various uses for which fats are PALM-TREES AND THEIR USES. 375 i m f Fig. 6. — Cabbage Palms in the "Savannah" of Cayenne 376 THE POPULAR SCIENCE MONTHLY. wanted. The thick, fibrous envelope of the nut has been much- used of late years in Europe. After being macerated, the fibers, called coir or cair, are combed. Ropes made of them are elastic and hardy against decay. They are worked into articles of esparto and brushes, and we tread them under feet in cocoa mat- tings. From the hard shell of the nut are made cups and dishes, which are susceptible of a ready polish, and can be carved. The leaves can be utilized, like those of other palms, but lack the sup- pleness of the leaves of other kinds. Not all the species of Cocos bear fruits as large as those of nucifera. The small species also contribute to the maintenance of man and industries. A considerable trade is carried on in the little cocoa of Central America (Cocos lapidea), which is some- times called the " convicts' cocoa," because prisoners polish or carve the hard egg-sized shells of the nuts, and make of them balls for mending stockings, bead-boxes, tobacco-boxes, and toys to sell to visitors. The same shell is in favor for making fancy buttons. Some other species of palm bear eatable or oleaginous fruits. The reddish -yellow, acorn-shaped fruits of the Paripon of Guiana (Guilielma speciosa) is highly esteemed. It is cultivated under different names in all the Central American countries. Beverages, and often alcohol, are obtained from the fruits of several other species. The Avoira, or oil palm, of Africa (Elo?is guineensis) is, after the cocoa, the most important of the palms as a commercial object. The numerous fruit-clusters of this palm, twice as large as a man's head, contain many fruits of the size of a walnut, the external envelope of which is charged with " palm- oil," a fat that is much used in soap-making, and is esteemed by Africans as an aliment. The kernel of the fruit affords an oil superior in limpidity and savor to that of the peri- carp. The African prod- uct of avoira fruits is es- timated at one hundred thousand tons a year. The manufacture of textile fabrics from palm-leaves has not been fully experimented upon. A few Central American palms and the oil-palm afford a strong and very fine fiber. Horticulturists have made much of palm-trees, and they are now abundant in the flower markets.

A HARVEST FROM THE OCEAN. 377 the tall Chamcerops ; the Corypha ; Weddell's cocoa, and two or three other species, are common as room ornaments. Other species do not bear the close air of apartments well, and are very liable to die if taken from the greenhouse or conservatory. Fig. 6 represents an avenue called the " Savannah of Cay- enne," which is composed of the straight-stemmed cabbage palm ( Oreodoxa oleracea of the Antilles), and has been much admired by travelers. Whenever one of the trees is blown down, or removed by any other cause, another one is at once planted in its place. Palm-trees rarely grow in numbers together. There are, how- ever, groves of a few species. The Attalea excelsa of America, which grows to the height of more than fifty feet, forms small woods. The Oreodoxa oleracea, or cabbage palm, is one of the largest spe- cies known, with its head often rising above the foliage of the vir- gin forest. Specimens of it have been found by measure to be about a hundred feet high, and the royal species of Havana rises to nearly one hundred and twenty feet. These plants are for the most part evergreen. They do not love climates of intermittent temperatures and abrupt changes, except in rare cases, of which the Areca palm of India {Areca catechu) affords an example. This species is extensively cultivated in the Indies, where the firm and astringent kernel of its nut (Fig. 7) is chewed with the betel-leaf by every native, as other people smoke or chew tobacco. A considerable number of fossil palms have been found, chiefly in the Miocene Tertiary of America, India, and Europe. — Trans- lated for the Popular Science Monthly from La Nature. A HARVEST FROM THE OCEAN". By Pkof. C. MORTON STRAHAN. THE compensations of nature are nowhere more forcibly illus- trated than along the bleak and rugged coasts of Scotland, Ireland, and Brittany, and their adjoining islands. Towering cliffs, whose scarred faces show no sign of verdure and defy all hope of cultivation, clasp the deeply indented bays in rude em- brace. Hamlets by the score hide themselves in the more shel- tered nooks, and the inhabitants find a precarious living by follow- ing the sea. Amid such unpromising surroundings Nature yearly plants and nourishes beneath the waves and along the wave- washed rocks a bounteous crop of sea-weed, which proves a genu- ine blessing to the dwellers on those shores. Not only is this both planted and nourished by the ocean, but it is to a great degree harvested by the same hand, and laid ready for use at the very doors of the fisherman's hut. The terrible storms which drive vol. xxxvi. — 24 378 THE POPULAR SCIENCE MONTHLY. the venturous seaman against hidden rocks, sweeping ashore his lifeless body and dismembered ship, also tear up great quantities of this valuable weed from the ocean's bed and dash them in con- tinuous bulwarks high up on the beach. Thus thrown ashore during the winter and early spring is a mass of what the natives call " deep-sea tangle," but which in the hands of the naturalist is recognized as a mixture of two kinds of Algce, termed respective- ly Laminaria digitata and Laminaria saccharina. In the spring and fall the milder storms add the "tangle-top" to the winter harvest. The tangle-top, as its name implies, consists of the tops or fronds of the same plants whose stems compose the " tangle " proper. These self -gathered masses constitute the greater bulk and the more valuable part of the annual yield. Together they are known as " drift-weed," as opposed to three varieties of Fuci (more commonly known as wracks) which grow on the rocks in that area covered by the rise and fall of the tides, and which, from the manner of their gathering, take the name of " cut- weed." Recourse must be had at this point to chemical analysis to reveal some useful ingredient which may justify this wet, salty, ill-odored mass of vegetable matter being dignified by the name of a crop. The analyses of the several species of Laminaria and Fuci show considerable variations ; it may, however, be taken that of the ordinary mixed mass of wet tangle and cut-weed about eighty per cent is water, fifteen per cent organic matter, and five per cent ash or mineral matter. In the same way it may be ad- mitted that one hundred pounds of the ash will contain, approxi- mately, twenty pounds of insoluble material, fifty pounds of alka- line carbonates and chlorides, twenty-two pounds of potash and soda, G"5 pounds of sulphurio acid in combination, and 1'5 pound of iodine in combination as iodides of potassium, sodium, etc. One hundred and fifty years ago such an analysis had never been made, nor would it have possessed any of its present suggestive- ness, for at that time iodine had not yet been discovered, and the burning of sea-weed for its ashes was practiced to but a very lim- ited extent. It required the pressure placed upon the soap-makers of France and England by the wars of the great Napoleon to force practical and wide-spread attention to the ashes of sea-weed. In virtue of that pressure the foreign supply of soda and potash salts in both of those countries was entirely cut off, and every domestic substance was ransacked for its contents of alkalies. This gave rise to that general movement among the Scotch and Irish peas- antry which resulted in the annual burning of the sea-weed har- vest, and the introduction of a new commercial body under the name of varec or kelp. Though the absolute yield of the alkali salts was small (about A HARVEST FROM THE OCEAN. m fifty pounds to one ton of the wet weed), so complete was the em- bargo against Spanish barilla and salt that kelp assumed a value as high as one hundred dollars per ton. During this halcyon period Scotland and her western isles reaped an annual income of nearly three million dollars, a sum which raised to affluence many a Scottish lord whose sole possession hitherto had been a long title and a few miles of barren sea-shore. But the end of the war, and the success of Le Blanc's process for making sodium car- bonate out of common salt, brought down the value of kelp with a sudden and disastrous drop. In 1831 the price had fallen to ten dollars per ton, a figure no longer remunerative. At this period kelp-making would have died out entirely but for the presence in it of a small quantity of iodine. The discovery of that element in 1812, by Courtois, and the demands for its manufacture, which had arisen between that date and 1840, were the sole cause for the continuance of kelp-making ; for kelp was then, and has since remained, the only practicable source of iodine in Europe. Dur- ing the past fifty years kelp has furnished fully ninety per cent of all the iodine and iodides which commerce has handled. The remaining ten per cent comes from South America, being derived from the well-known caliche of Peru. This substance, in being worked for the large amount of nitrate of soda it contains, also gives a small quantity of iodine as a profitable by-product. The caliche yields from two to three pounds of iodine per ton, against an average yield of twelve or fifteen pounds on the part of kelp. Many bothering questions of manipulation increase the labor and cost of the product from the former source, thus leaving the com- mercial advantage with kelp. With the origin of this new demand for kelp the industry received a strong impulse, and the price was restored to fairly profitable figures, ranging from fifteen to twenty dollars per ton, at which price it is still in commerce. It may be proper to note several interesting facts connected with the growth and composition of iodine-bearing weeds. All sea-weeds do not contain iodine, although that substance is uni- versally present in sea- water in the ratio of one to two hundred and. fifty thousand, proportions which, though minute, are amply sufficient to tempt assimilation by all growing sea-plants at least to an appreciable extent. Yet very few of them outside the family of Algai. contain even a trace of that element. So that to this family has been committed the chief work of withdrawing iodine from sea- water, and of concentrating it in plant-tissues in a form easy of extraction. The power of iodine absorption on the part of the Algol is the more remarkable when it is remembered that their growth transpires in the presence of three hundred times as much of the very similar element bromine, which latter, however, is ab- sorbed in only one tenth the quantity. The localities where they 380 THE POPULAR SCIENCE MONTHLY. grow, as well as the number of iodine-bearing plants, are very- limited. The shores of the British Isles and of Brittany are the spots most favored, owing to the presence of the Gulf Stream, which serves as the carrier of the iodine and of the temperature conditions necessary to the growth of the Algcz. By far the larger portion of the sea- weed harvest comes ashore in the early spring and in the late fall. The fall harvest, together with that which winter adds, is suffered in most localities to lie un- touched on the beach until it has been carried out to sea again and lost forever. It is only the spring crop which receives special care. Thousands of women and children, and a small sprinkling of men, may be seen nocking to the beach during the month of May, armed with rakes and wheelbarrows, or driving low carts, whose wheels are made broad enough to prevent their sinking in the sand. The wet weeds are raked into piles, and carried either by barrow or cart to a conveniently safe distance from the water's edge. Usu- ally a sheltered nook is chosen, if near at hand, and in it is stored a great mass of the weed. Here it is left to dry under the sum- mer's hot sun, meanwhile exhaling odors of no dainty description. There are well-recognized liberties and restrictions in regard to sea-weed accorded to landlords and peasantry who dwell along the shore. The landlords have most of the liberties, while the peasants enjoy the restrictions. Conflicts of sea-weed rights have been known to occur, in which cases the shillalah has had an im- portant share in the gathering of the crop. When the weed is dry — that is, in the latter part of July and the first of August — the owners of the sea-weed heaps undertake to burn them into kelp. This burning is done in the crudest and most wasteful manner. Shallow pits, often dug right in the sand, are filled with weed and the mass ignited. Upon the first charge fresh quantities of weed are thrown from time to time, the whole mass burning more or less rapidly in proportion to the dry- ness of the weed. There results, in the bottoms of these pits, a black mass resembling iron-slag in appearance, though not in hardness, which, being sprinkled with water while hot, breaks up into large lumps suitable for transportation. Owing to the care- lessness with which the weeds are raked up, this crude kelp-slag always contains a large percentage of sand and other impurities, sometimes amounting to one half the total weight of the product. The improvidence of this is the more marked in view of the small amount of valuable salts which even at best can be found in the kelp, and the rapid ratio in which the cost of transportation diminishes the profits when half of the slag is dead weight. The improvidence extends equally to the burning itself. This takes place in full access of air, and at a temperature so high as to vola- tilize much of the iodine. Besides, all the gaseous products of the A HARVEST FROM THE OCEAN. 381 combustion are lost and the escaped gases overcloud whole town- ships, and impart to miles of sea-shore the peculiar odor charac- teristic of burning kelp. To save these gaseous products by dis- tilling the weeds in closed retorts, at low temperatures, would mean the production, at little extra cost, of valuable amounts of ammonia, parafin, acetic acid, naphtha, etc. In addition, the char- coal left would be much richer in iodine than the ordinary kelp, and its mechanical form much easier of subsequent extraction. Attention has been called time and again to the enormous waste of material and the easy means of improvement in kelp-making, but thus far little inroad has been made into this European species of ancestor-worship. The crofters cling to traditional methods and primitive tools. When kelp, such as has been described, is brought into market, it is purchased by those directly engaged in making the salts of iodine and the alkalies. In their hands it becomes the subject of careful treatment to separate the valuable ingredients from the gross impurities with which they are associated. This is commonly done by breaking the kelp into small lumps and lixiviating in suitable vats filled with hot water or supplied with steam vapor. Such treatment, when sufficiently prolonged, dissolves out the alkaline and iodine salts, which need only the subsequent opera- tion of being allowed to settle and siphoning off to separate them from the insoluble matters. The liquor contains chiefly the chlo- rides, the sulphates, the sulphites, and the hyposulphites of sodium and potassium, as well as the iodides and bromides of those metals. By evaporating this solution, the greater portion of the chlorides and sulphates will crystallize out before the iodides, bromides, and lower sulphur compounds begin to deposit. The former may then be fished out of the evaporating pan, leaving a resultant mother-liquor rich in iodides. The hurtful sulphur compounds remaining are decomposed by excess of strong sulphuric acid, and then the proper quantity of manganese dioxide is added. This mixture is transferred to an iron retort and heated, the result of which is to liberate the iodine and part of the bromine present. The vapors of these elements are conducted into proper earthen- ware condensers, where the iodine is deposited as a black powder, and the small quantity of bromine as a dense brown liquid moist- ening the iodine powder. As before indicated, from twelve to twenty pounds of this crude iodine are obtained from the mother- liquor of one ton of kelp. There are several possible ways of puri- fying the crude iodine, in order to secure the iodine of commerce and also the bromine which had been its chief impurity. Even this purified iodine contains minute traces of bromine, owing to the difficulty of their perfect separation. If iodide of potassium is desired instead of free iodine, it is still necessary to produce 382 THE POPULAR SCIENCE MONTHLY. the latter, and froni it obtain the iodide by the action of potas- sium hydrate or caustic potash. Iodine, as a commercial body, has been subject to great fluctu- ations in price. It has ranged from a minimum of $1.50 to a maximum of $9.50 per pound, and is at present quoted at the fairly constant figure of $4 per pound. This harvest of sea- weed, whose transformation into iodine has been briefly traced, has been to a certain extent the subject of other industrial applications. In Ireland and the Channel Islands the weeds are used directly as a fertilizer. Its advantages in this line are chiefly felt in the Irish potato crop, where the potash of the sea-weed supplies a most important ingredient of that staple tuber. The presence, also, of small proportions of the earthy phosphates increases its value for fertilizing purposes. Attempts have been made to utilize these weeds in the manufacture of paper and textile goods, but with little or no success, owing to the fact that the true Algce are not fibrous in their structure ; nor is it sur- prising to find sea-weed quite extensively used as a fuel among a tenantry so poverty-stricken, and in a country so bare of combus- tibles. But the chief value of the sea-weed harvest remains in the monopoly of iodine which its tissues possess. Despite its many wasteful drawbacks, the kelp industry shows the respectable annual yield of six million dollars, much of which finds its way into the pockets of a very destitute tenantry. In those districts where the winter supply is carefully gathered and burned, the production of kelp has had very beneficial effects by employing and remunerating the most indigent classes at a time when they would otherwise be totally unproductive. BIRDS WITH TEETH. By OTTO MEYER, Ph. D. THE birds of our present world, however different they may be from each other in size, shape, color, etc., are remarkably uniform in their anatomical construction. Adapted to a life in the air, they all possess bones which are more or less pneumatic — that is, contain air-cavities, to lessen the weight of the skeleton. Altogether the reduction of weight has been brought down to per- fection, and a flying bird carries very little, if any, unnecessary substance. Locomotion in the air requires, further, a vigorous action of the wings, and such a motion could hardly be executed in presence of a loose and shaky body. But the skeleton of the body of a bird is not loose ; on the contrary, it is very solid. The vertebrae of the backbone are grown together and form a firm BIRDS WITH TEETH. 383 column. With this column the broad ribs unite in the back, while in front they are held together by the sternum ; and to make this cradle of bones more compact and fit to resist the action of the wings, and to protect the interior organs, the ribs touch each other with what the anatomists call "uncinate pro- cesses." Whoever is called upon to carve at the table a chicken or a turkey will experience how solid and protective the construc- tion of the skeleton of the body is. If the main body is in this way compact and immovable, some other part must be so much the more flexible, and this is the neck. If we watch a swan oiling its feathers with its bill, see the cervical evolutions of a flamingo, or an owl sitting with its head reversed, we are apt to experience a painful sensation in our necks and may wonder whether the bird will assume its normal position without breaking something. But all these motions are executed with the most perfect ease and security, and the construction of the vertebrae, which enables the birds to perform them, is simple and effective. These vertebrse do not articulate with each other by plain faces as the vertebrae in our bodies, but the articulations are saddle-shaped, so that the prominence of one vertebra fits into the excavation of the next one, and vice versa. If we take two adjoining vertebrae of the neck of a bird and try their motion, we shall find that this articulation admits two ways of turning — from one side to the other as well as up and down. This saddle shape of the articular face of the cervical vertebrae is found with- out exception in all existing birds and in no other animal. There are other features which are met with in all birds and exclusively in them — for instance, the plumage. The horny bill is without teeth. The vertebrae of the tail are grown together and form a plowshare- shaped bone. This bone supports the tail feathers, which can be opened and closed like a fan, and which serve as a rudder and a parachute. The bones of the anterior ex- tremities are transformed in such a way that they form an excellent framework for the wings; but, although the anatomists distinguish easily radius, ulna, digits, etc., one would hardly sus- pect that these wing bones are perfectly analogous to those in the fore-feet of quadrupeds, or in our arms and hands. Now let us turn our attention to the reptiles which exist at the present time — to the lizards, crocodiles, snakes, and turtles. These cold-blooded, scaly animals seem to have nothing at all in Fig. 1. — Vertebra op a Bird with Saddle -shaped Ar- ticular Face. 3*4 THE POPULAR SCIENCE MONTHLY Psychozoic. < i — -=== -Terti ary. ~& i * i i-A' 1 1 1 heavens, with the seven mov- gfek I ing luminaries, and the dark earth, with m m^< m / ^s seas' ^G ma^e Prmciple predomi- ^ W / nated above, the female principle pre- ^^ ^p ^y dominated below, as Father Heaven and Mother Earth, each having an all-per- vading spirit, but with unlike influence. The body comes from and depends upon the earth ; the soul comes from and returns to the heavens. The rocks are the bones of the divine body, the soil is the flesh, the metals are the nerves and veins ; the tide, wind, rain, clouds, frost, and dew are all caused by its respirations, pulsations, and exhalations. Originally the mountains rose to the firmament, and the seas covered the mountains to their tops. At that time there was, in the divine body, no life besides the divine life. Then the waters subsided ; small herbs grew, and in the lapse of cycles developed into shrubs and trees. As the body of man, unwashed for years, breeds vermin, so the mountains, unlaved by the seas, bred worms and insects, greater creatures developing out of lesser. Beetles in the course of ages became tortoises, earth-worms became serpents, high-flying insects became birds, some of the turtle-doves became pheasants, egrets became cranes, and wild cats became tigers. The praying mantis was by degrees transformed into an ape, and some of the apes became hairless. A hairless ape made a fire by striking crystal upon a rock, and, with the spark struck out, igniting the dry grass. With the fire they cooked food, and by eating warm victuals they grew large, strong, and knowing, and were changed into men. There is a story that the ape who first taught cooking had a peculiar origin. He was imprisoned, from the beginning, in a rock on the sea-shore. The waves beat on the rock century after century, and at last wore away all except the ape that had been its center. Then the sun warmed him, and the winds breathed upon him, till he became alive, and with a divine impulsion went and taught his kind to cook their food. Khu says : " In the early days of man there were peace and plenty, because no one disturbed or maltreated the body of God. Those who saw a stone removed from its natural site, wept, and THE CHINESE THEORY OF EVOLUTION. 399 carried it back and put it in the place from which it came. Chil- dren were taught that if they found a piece of metal they must not touch it. No silver, nor gold, nor jade was to be seen in any dwelling. To the wise, dreams were given, in which the universal parent spoke, saying : ' Child, the gold, the jade, the metals, and the gems are all parts of my body. Touch them not, nor meddle with them to my hurt and yours. To take stones from the earth is to dislocate the bones of one's parent ; when the parent suffers, the dependent child is harmed.' In those days the soil was red and rich ; it was heavy as iron, and so ductile that it could be drawn into filaments. There was no need of fertilizing the fields. Whatever was planted grew quickly, and the kernels of grain were as large as chestnuts, and the potato-tubers were as large as squashes now are. The products of the earth were so nutritious that one meal a day was sufficient, and so luscious were they that condiments were needless. It is the disrespect shown to the di- vine body that has made the life of man so hard. One should be content with what may be had without deeply disturbing the soil. The displeasure of Heaven is often manifestly visited upon the agriculturists who give the land no rest, and the lightning fre- quently strikes those who are at work in the fields. Those who walk on mountains soon tire, because they tread upon the bones, while those who keep to the artificial highways are not so soon fatigued." This pantheistic theory being in its loftiest conceptions too abstract for the masses, it is expressed by them in the assertion that " there is a god to every eight feet of space." Every tree, grotto, and hummock has its tutelary deity. Consequently, no man begins to dig a cistern, to remove earth from a hill, to cut a stone, or to till a garden, without offering propitiatory gifts to the local divinity. If fever, headache, or dyspepsia follow the effort, the displeasure of the god is believed to be its cause, and the work is apt to be abandoned. It is at once apparent that this pantheistic theory of evolution offers serious hindrance to the utilization of the metals contained in the mountains, to the opening of mines, the building of rail- roads, and the erection of structures requiring deep foundations. It has prevented the Chinese from availing themselves of the vast mineral resources of their country, from leveling thorough- fares where they are pressingly required for traffic, and from full use of the products of the earth in promoting the well-being of man. It is the chief reason why the emigration of hundreds of thousands of men in search of work has now become necessary. If the Chinese were unhampered by fear of the invisible ones who are considered by all to be the real proprietors of the land, they would have an abundance of lucrative work within their own 4oo THE POPULAR SCIENCE MONTHLY. borders, and they need not then afflict other countries by their immigration. The losses that accrue to them through this false theory are both positive and negative. It occasions an enormous outlay upon profitless offerings that must be bought with money earned by hard labor; and it prevents their use of the wealth stored in their lands. Affecting daily the welfare of hundreds of millions of persons, it well illustrates the practical evil of false doctrine, and, by contrast, shows the great economic value of truth. SKETCH OF ALEXANDER WILSON. A PECULIAR interest attaches to the lives and labors of pio- neers. The circumstances which led to the discovery of a new continent, the first application of one of the forces of nature to the service of man, the making of the first instrument for viewing the stars, and the first description of the animals, plants, or physi- cal features of a country, always have eager readers. Then, too, the personality of a man who has the courage and originality to set forth into an untrodden field is generally picturesque and inspiring. All these claims to attention are possessed by the pio- neer American ornithologist. Alexander Wilson was born on the 6th of July, 1766, at Paisley, in Renfrewshire, which lies just south of the river Clyde. His father, Alexander Wilson, was a weaver, and reached the age of eighty-eight years, dying in 1816. During the latter part of his life, at any rate, the father was rated as a most exemplary citi- zen, but there is a glamour of "moonshine" about his early man- hood, in the sense that, when not occupied with tending the loom, he operated a " wee still," from which trickled good Scotch whisky that was consumed without paying tribute to the tax-collector. This has naturally been denied, but not with entire success. His wife was a Mary McNab, of a strictly pious character, and with the beauty that frequently accompanies a tendency to consump- tion. Of this disease she died when young Alexander, who was one of three children, was ten years old. Like many devout Scottish folk, the parents of " Alic," espe- cially his mother, cherished the ambition that their boy should " wag his head i' the puppit yet," but his genius did not lie in the direction of the ministerial office. He attended the Grammar School of Paisley, but his schooling must have been interrupted and of no great amount, for much of his boyhood was otherwise occupied, and his deficiencies in grammar, spelling, etc., clung to him till manhood. He is known to have struggled with his back- wardness in arithmetic after emigrating to America. His hand- SKETCH OF ALEXANDER WILSON. 401 writing was called excellent, and his language was simple and idiomatic. The taste for reading, which he early developed, largely made up for his scanty schooling. At one time he was sent to be a herd on a farm called Bakerfield, not far from Pais- ley, where he remained probably not more than a single sum- mer. It is said that " he was a very careless herd, letting the kye transgress on the corn, being very often busied with some book." In his thirteenth year he was bound apprentice as a weaver, for three years, to his brother-in-law, William Duncan. Having served out his time in 1782, he continued a weaver " by constraint, not willingly," for four years, living part of the time under his father's roof in Paisley and in Lochwinnoch, and finally with his brother-in-law at Queensferry. His taste was for outdoor life, and he had inherited a feeble constitution from his mother, so that the loom was irksome to him both mentally and physically. During this period young Wilson began to contribute verses to the local newspapers. His best piece, however, " Watty and Meg," was published in 1792, as a penny chap-book, without his name, and was ascribed to Robert Burns. The latter, who lived not far away, and was but six years older, 'strengthened the compliment by avowing that he should have been glad to be its author. Wil- son's descriptive pieces are interesting, from the evidence they give of his natural fondness for the woods and fields. After a while Duncan decided to " travel " as a peddler through the eastern districts of Scotland, and invited Alexander to accom- pany him. Accordingly, the two abandoned the loom and entered upon their new occupation. The Scotch peddler of that time was generally a man of shrewdness and common sense, probably re- sembling the best type of our own departed Yankee peddler, and was generally respected by the common people, but often sus- pected and despised by the wealthier. This occupation, although it delivered Wilson from the confinement of the weaving-room, was not all sunshine. It involved trials and rebuffs, which to a man, as Grosart * calls him, " of sensitive, strangely refined if also in elements as strangely coarsened temperament," must have been hardly borne. His " Journal as a Pedlar," several poems bearing on his experiences of the road, and his earlier letters, give a real- izing sense of the lights and shadows of this kind of life. In ad- dition to his trading, he solicited subscriptions for a volume of poems, which he published in 1790. In a short time he dropped the pack and returned to his hated trade of weaving. Being in ill-health and sorely oppressed by poverty, he was at this period much given to despondency. Yet he * " The Poems and Literary Prose of Alexander Wilson," edited, with Memorial Intro- duction, Essay, etc., by the Rev. Alexander B. Grosart, two vols., Paisley, 1876. vol. xxxyi. — 26 4o2 THE POPULAR SCIENCE MONTHLY. had a liumor wliich enabled him at times to joke about his neces- sities. He had a gift of satire, also, which got him into some trouble, but which was the cause of his taking the first step in the path that led to fame. Industrial affairs in Great Britain at that time were greatly unsettled. Many of the Paisley weavers were unemployed, and capital and labor were arrayed against each other. Some of the turbulent spirits among his fellow weavers induced the enthusiastic young Wilson to use his talent for verse- making to abuse the capitalists. Several poems of his, portraying in no flattering light certain local petty tyrants, were adjudged libelous, and Wilson, who manfully acknowledged their author- ship, was fined heavily, and condemned to burn the poems in pub- lic. Being unable to pay the fine, he was sent to jail. In this hour of gloom, Wilson's eyes were turned to the New World. Attracted by the chances for winning his way open to a free man in a new country, he determined to emigrate. Accord- ingly, he and his nephew, William Duncan, sailed from Belfast Loch, Friday, May 23, 1794, and after a voyage of over seven weeks landed at Newcastle, Delaware. Wilson was then twenty-eight years old. He and young Duncan went first to Wilmington, and from there to Philadelphia, looking for employment at weaving. At the latter place, he writes in his first letter home to his father and step-mother, " we made a more vigorous search than ever for weavers, and found, to our astonishment, that, though the city con- tains between forty and fifty thousand people, there is not twenty weavers among the whole, and these had no conveniences for journeymen, nor seemed to wish for any: so, after we had spent every farthing we had, and saw no hopes of anything being done that way, we took the first offer of employment we could find, and have continued so since." This employment was in the shop of a copper-plate printer. The above quoted letter was a long and very newsy one, and contains Wilson's first observation of the feathered creatures that were to make his fame. He writes : " As we passed through the woods on our way to Philadelphia, I did not observe one bird such as those in Scotland, but all much richer in color. We saw a great number of squirrels, snakes about a yard long, and some red birds, several of which I shot for our curiosity." Wilson remained in his first found employment but a few weeks. After that he worked at his trade of weaving at a place ten miles north of Philadelphia, and for a short time in Virginia. In 1795 he tramped through northern New Jersey as a peddler. He had been in America but little over a year when he took up school-teaching, and at this occupation he succeeded remarkably well, although it gave him only a scanty income. He first opened a school at Frankford, but soon gave it up to become master of the school at Milestown, in Philadelphia County, where he taught for SKETCH OF ALEXANDER WILSON. 403 nearly six years. His own education had been limited ; so, after he began to teach, he had to study diligently to make up his deficien- cies. He advanced so far in mathematics that he was enabled to take occasional employment as a surveyor. After leaving Milestown he taught for a while at Bloomfield, N. J., but he found this place disagreeable, and he was at the same time burdened with a trouble, only dimly revealed in his letters, but in which one of the Milestown young ladies figured. He be- came very despondent, and even thought of returning to Scotland. It was not long before he obtained a school at Kingsessing, near Gray's Ferry, on the Schuylkill. His removal to this place was attended with important results. He became acquainted with William Bartram, whose famous garden was not far away, and with Alexander Lawson, the engraver, both of whom became his steadfast friends. Bartram lent him books, among them, the works of Catesby and Edwards. In the parts of these works relating to American birds, Wilson's own acquaintance with the birds was enough to show him an exasperating number of errors, false theo- ries, and caricatured figures. During the early part of his life at this place Wilson was so despondent that Lawson at one time feared for his reason, and advised him to give up poetry and his flute, which seemed to increase his melancholy, and to take up drawing. This accomplishment does not seem to have come very naturally to him, for he made a failure of the landscapes and human figures which Lawson set before him. Still, the statement of an American writer, that he was " without any previously suspected aptitude," is denied by Mr. Grosart, who adds that drawings by him before he left Scotland are preserved in the Paisley Museum with the col- lection of Wilson's manuscripts. Bartram and his niece, Miss Nancy, started him again on easier subjects, first flowers, and then birds, with which he made encouraging success. It is in a letter to one of his Scottish biographers, his old friend in Paisley, Mr. Thomas Crichton, under date of June 1, 1803, that Wilson's determination to study the birds of America is earliest recorded. " Close application to the duties of my profession," he writes, " which I have followed since November, 1795, has deeply injured my constitution, the more so that my rambling disposition was the worst calculated of any one's in the world for the austere regularity of a teacher's life. I have had many pursuits since I left Scotland — mathematics, the German language, music, draw- ing, etc., and I am now about to make a collection of all our finest birds." At first he devoted only leisure hours to the birds, and his figures " were chiefly colored by candle-light," but he soon be- gan to make longer and longer expeditions. In October, 1804, he set out with two companions, on foot, to visit Niagara. From there he went through the lake region of central New York, visit- 4o4 THE POPULAR SCIENCE MONTHLY. iiig his sister and her children, who were living on a farm that Wilson and his nephew "William had bought together. He made his way home down the Mohawk Valley to Albany, and thence by boat to New York. In this journey, occupying two months, he traversed over twelve hundred miles. Winter overtook him in the midst of it, so that the latter part of it was made " through deep snows and almost uninhabited forests ; over stupendous mount- ains and down dangerous rivers." The trip seems to have bene- fited both his health and spirits, for in his account of it, written to Bartram,he expresses eagerness for wider explorations and new discoveries. " With no family to enchain my affections, no ties but those of friendship, and the most ardent love of my adopted coun- try ; with a constitution which hardens amid fatigues, and a dispo- sition sociable and open, which can find itself at home by an Indian fire in the depth of the woods, as well as in the best apartment of the civilized [world], I have at present a real design of becom- ing a traveler. But I am miserably deficient in many acquire- ments absolutely necessary for such a character. Botany, miner- alogy, and drawing I most ardently wish to be instructed in, and with these I should fear nothing." How oblivious to matters of detail his enthusiasm made him can be judged, Ord * remarks, from the fact that at this time Wilson's available cash amounted to seventy-jive cents. Two of the birds which he shot in New York, one being the Canada jay, were unknown to Wilson's associates. He made careful drawings- of them, and got Mr. Bartram to send them to President Jefferson, whom Wilson much admired. The Presi- dent, who was quite an amateur naturalist, replied with a very ap- preciative letter, in which he put Wilson on the track of a certain sweet-singing and very unapproachable bird. He had " followed it for miles without ever, but once, getting a good view of it," and had for twenty years tried to get a specimen without success. "After many inquiries and unwearied research," says Ord, "it turned out that this invisible musician was no other than the wood robin, a bird which, if sought for in those places which it affects, may be seen every hour of the day." The next summer Wilson announced to Bartram his determination to make a collec- tion of drawings of the birds of Pennsylvania, and sent him twen- ty-eight for criticism. The scope of his undertaking was extend- ed, within a few months, so as to include the whole United States. He had planned an expedition down the Ohio and Mississippi Riv- ers for the summer of 1806 with Bartram ; but the latter, who was nearly seventy years old, gave up the idea. Wilson, who had heard that explorers were to be sent up the Red and Arkansas Rivers, * " Life of Alexander Wilson," by George Ord. In Volume IX of the " American Or- nithology." SKETCH OF ALEXANDER WILSON. 405 through the recently acquired Territory of Louisiana, then offered himself to President Jefferson for this service. " Mr. Wilson," says Ord, " was particularly anxious to accompany Pike, who com- menced his journey from the cantonment on the Missouri, for the sources of the Arkansas, etc., on the 15th of July, 1806." But no reply was made to his application. In April he was engaged by the publishers, Messrs. Bradford and Inskeep, as assistant editor for the revision of Rees's " New Cyclopaedia," on " a generous salary," namely, nine hundred dol- lars a year. He now gave up school-keeping, which had been his calling for ten years. While in this position, he made known his plans for the " American Ornithology " to Bradford, who readily agreed to undertake its publication. A prospectus was immedi- ately issued, and a year later, in September, 1808, the first volume of the work appeared. In the fall of that year he made a trip through New England, " in search of birds and subscribers." On the way from Philadelphia he stopped at Princeton, to show his work to the college professors. He expected to get some valuable information on American birds from the Professor of Natural His- tory, " but," he writes, " I soon found, to my astonishment, that he scarcely knew a sparrow from a woodpecker." Wherever he showed his book to college professors, and other literary men, the highest praise was lavished upon it, but subscriptions were not so freely forthcoming, the price, one hundred and twenty dollars, being a serious obstacle. He wrote from Albany, on his way home, that he had obtained only forty-one subscribers. One of the less intelligent personages, whose favor he had sought, was the then Governor of New York — Daniel D. Tompkins. This magnate, as Wilson informs us, " turned over a few pages, looked at a picture or two, asked me my price, and, while in the act of closing the book, added, ' I would not give a hundred dol- lars for all the birds you intend to describe, even had I them alive/ " He soon set off again on a trip through Baltimore, Washington (where he was received " very kindly " by Jefferson), and other Southern cities, and when he reached home had in all two hundred and fifty subscribers. In the South he shot several new birds. It was now deemed advisable to add three hundred impressions of Volume I to the two hundred first struck off, and the second volume started with an edition of five hundred copies. His un- dertaking had already won him " reputation and respect," but the pecuniary return was still doubtful. Volume II of the " Ornithology " was ready in 1810, and in February of that year Wilson set out on another hunt for new specimens of the feathered tribes and those rare birds — subscrib- ers. His varied adventures on these expeditions, and his impres- 4o6 THE POPULAR SCIENCE MONTHLY. sious of the people and places that he visited, are delightfully recorded in the letters which Mr. Grosart collected. At Hanover, Pa., he met a judge who condemned his work because " it was not within the reach of the commonality, and therefore inconsistent with our republican institutions." Wilson turned the tables on this learned man by showing that the judge's elegant three-story brick house was open to the same objection ; and then in a more serious vein pointed out to him the benefit which a young, rising nation can derive from science, " till he began to show such symptoms of intellect as to seem ashamed of what he said." From Pittsburg Wilson made his way in a skiff down the Ohio over seven hundred miles, nearly to Louisville, stopping at the important towns on the way. At Louisville one of the persons on whom he called was Audu- bon, then thirty years old and engaged in business. Audubon has left an account of this meeting, in which he thus describes Wilson's physical appearance : " How well do I remember him as he walked up to me ! His long, rather hooked nose, the keenness of his eyes, and his prominent cheek-bones, stamped his counte- nance with a peculiar character. . . . His stature was not above the middle size." Audubon claims that he was about to subscribe for the " Ornithology," but a complimentary reference to his own knowledge of birds, spoken in French by his partner, checked him. "Vanity and the encomium of my friend prevented me from subscribing," he writes, and to this he adds that he lent some of his drawings to Wilson, and hunted with him, obtain- ing some birds which the latter had never seen before. Audu- bon states also that being in Philadelphia some time afterward he called on Wilson, who received him with civility, but did not speak of birds or drawings. Against this story must be set the following extract from Wilson's diary published in the ninth vol- ume of the " Ornithology " : " March 23d, I bade adieu to Louis- ville, to which place I had four letters of recommendation, and was taught to expect much of everything there; but neither received one act of civility from those to whom I was recom- mended, one subscriber, nor one new bird ; though I delivered my letters, ransacked the woods repeatedly, and visited all the char- acters likely to subscribe. Science or literature has not one friend in this place." " We must take Audubon's account," says his own biographer, Robert Buchanan, " cum grano salis," while Grosart, eager in defense of Wilson, does not hesitate to call it " a tissue of lies," except his admission that vanity kept him from subscribing to Wilson's work. Turning southward, Wilson crossed Kentucky to Tennessee, and proceeded through the Chickasaw and Choctaw countries to Natchez, and thence went to New Orleans. SKETCH OF ALEXANDER WILSON. 407 By persistent labor the successive volumes of the "Ornithol- ogy " were issued up to the seventh, which appeared in the spring of 1813. On the 6th of July in that year he wrote : " I am my- self far from being in good health. Intense application to study has hurt me much. My eighth volume is now in the press and will be published in November. One volume more will complete the whole." But he was not to see the appearance of even the eighth volume. The unremitting labor of that summer, carried on in the city, where even his tramps with his gun were cut off, so reduced his strength that he succumbed to an attack of his old enemy the dysentery and died, August 23, 1813, at the age of forty- seven. The immediate cause of the attack was his swimming a river in pursuit of a rare bird that he caught sight of while visit- ing a friend. Wilson died unmarried, although in his letters he condemns celibacy, and shows that he was not indifferent to female companionship. In fact, he was to have married a Miss Miller, whom he made one of his executors. George Ord, who had accom- panied Wilson on some of his trips, was made a co-executor, and completed the publication of the " Ornithology," prefixing to the last volume a life of the author. The original edition of Wilson's great work is now rare. It comprises nine thin folio volumes, about eleven by fourteen inches in size. Several birds are figured on each plate — the smallest ones of life-size, the others reduced. An edition in three volumes, including the birds afterward described by Prince Bonaparte, was issued in 1829-'36,* and another in four volumes,, edited by Prof. Robert Jameson, in 1831. Wilson was no compiler ; he took his facts from his own obser- vations, or the accounts of those who had known the birds for a lifetime. He had, further, as Grosart says, a " magnetical sympa- thy with the birds whereby his descriptions of their looks and ways and faculties take the coloring of so many little biographies of personal friends." Sir William Jardine says of Wilson : " He was the first who truly studied the birds of North America in their natural abodes, and from real observations; and his work will ever remain an ever-to-be-admired testimony of enthusiasm and perseverance — one certainly unrivaled in descriptions ; and if some plates and illustrations • may vie with it in finer workmanship or pictorial splendor, few, indeed, can rival it in fidelity and truth of deline- ation." * " American Ornithology," by Alexander Wilson and Prince Charles Lucien Bona- parte.

Editor Popular Science Monthly : DEAR SIR : The article in your Novem- ber issue, by Joel Benton, on "The Decadence of Farming," greatly interested me, as it must every lover of our country, and it suggested several questions which I believe should be considered, that we may get at the facts. The reasoning is that, because farming has decayed at the same time that a protect- ive tariff has prevailed, which has enhanced, as it is claimed, the cost of what the farmer has had to buy, therefore the tariff is re- sponsible for this decay. Saying nothing of the claim that the tariff does in the long time enhance the price of what the farmer has to buy, let us ask how free trade has helped the farmers in Great Britain. Is it not a fact that during these same years farm- ing has decayed there fully as much as in our own country? The wonder is how, with produce so low, the Irish farmers can pay their rent, and many can not, and the land-owners' profits have almost disap- peared. A Yorkshireman recently told the writer that he knew of many large farms the owners of which would be glad to give a lease for a term of years for no rent, if the land could be kept up. Now, by parity of reasoning, may we not say that, seeing farming has decayed in Great Britain, at the same time that free trade has prevailed, which has brought down the price of what the farmer has to buy, therefore free trade has caused the decay of farming ? Is it any better in free-trade Holland, from which the farm laborers are coming to the writer's own community, because the best farm la- borer there can get but forty cents a day, whereas here he gets at once more than double ? Do not these facts suggest the question whether there are not other causes besides tariff or free trade which may account for this manifest decay of farming ? Has not the wonderful cheapening of transportation brought cheaper and, for a time, more fertile soils into competition with the dearer and worn-out soil of our older States ? Cereals and meat and wool can be raised so cheaply on these new lands that the Western farmer, with the low cost of transportation added, can undersell the farm- ers of the older States. The same is true in the case of Great Britain. And this power to undersell is increased by the use of ma- chinery in farming, which use can be so much greater and more effectual on the large farms of the new States than in the older States. A bushel of wheat or corn can be raised with a small part of the labor cost in Kansas or Dakota as compared with New York. The result is, that in the older States the farmer is compelled to look for his profits to raising the products that will not bear transportation, cither because they are perishable, as milk, or because they are too bulky, as hay. He must depend upon the near-by market, and supply it with what the farmers of the West can not send it. Does not this suggest another thought ? We must look for relief, not in the direction of urging more to engage in farming, but by finding, if possible, other employments for men which are more profitable; and this, many of us still believe, can be done better with a wisely adjusted protective tariff than with free trade, which would tend to crowd still more the already overfull ranks of the farmers. John R. Thurston. Whitinsville. Mass., October 30, 18S9. A REMONSTRANCE. Editor Popular Science Monthly: Sir: I have been accustomed to read with a high degree of pleasure the contribu- tions of Mr. Grant Allen which I have seen from time to time in your pages. Read- ing in your December number his " Plain W°ords on the Woman Question," copied from the "Fortnightly Review," I rubbed my eyes once or twice over the following words, which seem, after a second or third perusal, much too plain : " Whether we have wives or not — and that is a minor point about which I, for one, am supremely unprejudiced — we must at least have mothers." Calving must go on, no doubt, if the race of horned cattle is to be kept up, and it is not important that calves should know their own fathers, or have an acknowledged par- entage on the male side. It is quite other- wise with human beings, and I submit that no teacher of biology can afford to be with- out a bias in favor of wives, looking strictly at human progress, which is the great desid- eratum of the article in which this extraor- dinary passage occurs. Possibly the words quoted may have a biological meaning somewhat different from the obvious meaning. If so, Mr. Grant Al- len should be cautioned, when writing for the laity, to use the kind of language which they understand. If the obvious meaning is the real meaning, I have only to say to him, " Never more be officer of mine." H. W. New York, November 30, 18S9. Mr. Allen, we are sure, is the very last man who would deliberately say anything calculated to encourage immoral tendencies. CORRESP ONDENCE. 409 There is, however, in this particular contro- versy, much excuse for the plain speaking to which our correspondent takes exception. The real woman question, which, as Mr. Al- len points out, is whether woman shall un- sex herself or not, has long been obscured by a sort of sentimental glamour which is daily exerting the worst kind of influence in society ; and when the scientific man takes up the subject, it becomes his duty, if he would be true to the spirit of his craft, to set forth in the strongest light the essential facts of the case. All through his article it is the biological question involved which Mr. Allen keeps to the front, and in the passage complained of he, as we read him, is simply emphasizing the supreme importance of this aspect of the subject. — Editor. ENVIRONMENT AND THE REPRODUCTIVE POWER OF ANIMALS. Editor Popular Science Monthly : I have read with great interest an article in the November number of " The Popular Science Monthly " entitled " Conditions af- fecting the Reproductive Power of Animals," and, while I fully agree with the facts as stated, it seems to me that the manner in which- it is written savors overmuch of the " carpenter theory of creation." I do not deny that " the activity of the reproductive function is in proportion to the unfavorableness of the embryonic environ- ment " ; but is not this a fact rather than a law ? It is true that the power of producing young in immense numbers is the conditio sine qua non among lower orders of ani- mals, but should we not look deeper for the reason of this power ? Are there any laws in nature which exist simply because they are good ? Among the lower orders of animals the weight of each offspring is much less in pro- portion to that of the parent than among the higher. The organization of the lower or- ders being much simpler than the higher, the offspring can be brought to perfection in a much shorter time. Therefore, each in- dividual offspring of the lower orders is pro- duced with much less expenditure, on the part of the parent, of both matter and vital- ity. Were these the only differences, they would be sufficient to account for a vast dif- ference in reproductive power. This reproductive power is fostered by natural selection. Among those species whose young are exposed to so many chances of destruction, those varieties which possess the greatest reproductive power are more likely to survive in the struggle for exist- ence, and will transmit to their offspring their more vigorous reproductive power. To say that the reproductive power of an animal can be affected directly by anything which may happeD to the offspring after birth reminds us of the belief current among children that, if a lost tooth be swal- lowed by a dog, a dog's tooth will grow in its place. We know that the existence of a species in any given state depends upon certain con- ditions. While the study of that species may teach us much concerning those condi- tions, it is necessary for us 10 take a wider and deeper view before we can discover the causes which led to them ; and we should ever keep in mind the fact that while the spe- cies owes its existence, in any given state, to those conditions, the conditions were not necessarily created by Nature for the sake of preserving the species in that particular state. Nature helps those, and only those, who help themselves. Charles A. Peple. Richmond, Va., November 4, 18S9. A CORRECTION. Editor Popular Science Monthly : Dear Sir : My attention has been called to a slip occurring in my article in the April issue of the " Monthly." In the sentence (in the foot-note, page V27) reading "... Add to this the confession of an exposed medium, Mr. D. D. Home," etc., the exposed medium is not D. D. Home, but one cited by him as exposed. The only hint I have as to the ori- gin of the printed version is from my frag- mentary notes for the paper, in which the words stand thus : " Add to this the confes- sion of an exposed medium (D. D. Home, ' Lights and Shadows of Spiritualism,' etc.)." I remember deciding to omit all mention of names wherever possible, and must have crossed off part of the parentheses instead of all. I am very sorry that so slight an error should have ended in throwing blame where it did not belong, and especially so as my point was simply that a medium was exposed in the manner indicated, it being en- tirely immaterial who the medium might be. I must further apologize for the lateness of my writing, on the plea of a six months' absence abroad, and the consequent accumu- lation of duties awaiting me on my return. Truly yours, Joseph Jastrow. Madison, Wis., Oct 31, 18S9. 4-io THE POPULAR SCIENCE MONTHLY EDITOR'S TABLE. TOZSTOrS " CONFESSION." AMONG the numerous writings from the pen of Count Tolstoi which have of late been made accessible to the English reader is one entitled " My Confession." In this work the author tells us that, having in his youth led the life of a pleasure-loving man of the world, and in his maturer years of a literary man in considerable repute, he woke up in middle life, when all his outward circumstances were highly prosperous, to find that life to him seemed to possess no meaning and no value. He could find no answer to the Carlylean questions "Whence?" and "Whither?" and so distressed was he thereat that for a long time he was haunted by the thought of suicide. He had recourse to science, and could get no light ; to philosophy, and could reap no consolation. It seemed to him as if some tyrant had called him into exist- ence simply to make a mock of him, by hiding from his eyes the answer to life's riddle — by implanting in him an in- stinctive love of life, and yet depriving him of the knowledge which alone would supply a rational motive for living. The nature of Tolstoi's trouble is fully explained in his book. His youth had been one of passion and riot, un- guided by any principle save the loose code of honor prevalent in military circles. As an author he had encount- ered men with whom literature was a means for the gratification of vanity and nothing more, whose aims were sordid, whose ideas were conventional, and whose lives were actually worse than those of the wild companions of his youth. Yet these men set themselves up for guides of society and final arbiters in all questions of taste and morals. Tolstoi himself had caught their tone, and for a time imagined that, because he enjoyed popularity as a writer, he must necessarily be a very superior per- son. According to the ideas prevalent among his literary friends, the world existed for hardly any other purpose than to provide them with the oppor- tunity for airing their superiority. It is not surprising that a man of Tolstoi's sensibility should eventually have been led to see the falsity of this whole view of life ; the only wonder is that he did not revolt against it sooner than he did. The thoughts that came to him toward middle life have come to some others much earlier. The poet Clough was only twenty- two when he wrote : " How often sit I poring o'er My strange distorted youth, Seeking in vain, in all my store, One feeling based on truth ; Amid the maze of petty life A clew whereby to move, A spot whereon in toil and strife To dare to rest and love ! " The life of Tolstoi had been essentially based upon privilege. He had lived above the mass of mankind, and had imbibed the narrow ideas of an exclu- sive set. He had not taken humanity into his thoughts, except for purposes of literary treatment; and, therefore, when a period of calm reflection came, though his intellectual pride took flight, and his false ideas stood confessed in their falsity, what to do he knew not. It seemed to him that he had to con- struct a new philosophy of life, and in the search for a solid basis for such a philosophy he endured the distress which he has so vividly described. He attacked the problem, however, from the wrong side, asking questions which only metaphysicians or theologians have ever attempted to answer, and which have never been answered in any satis- EDITOR'S TABLE. 411 factory manner. After many wander- ings and many perilous lingerings on the very verge of despair, he bethought him- self of the thousands and millions of human beings who go about their daily tasks and take up their daily burdens without repining or misgiving, who find a natural sweetness in life, and never think of worrying themselves over ques- tions of ontology or metaphysics. These, he said to himself, must possess the true secret of life, and the best thing I can do is to learn it of them. Tolstoi was here getting upon solid ground. His previous life had been governed without any reference to car- dinal principles of duty or to the essen- tial relations of human beings to one another. One of the aphorisms of the founder of the Positive Philosophy is that between individual man and the universe humanity is needed as media- tor. Suppress humanity, that is to say, suppress all true thoughts in regard to humanity, suppress the sense of inclu- sion in and identification with the great human whole, and individual man is indeed a poor, defenseless thing, or, as Matthew Arnold has expressed it — " A naked, eternally restless mind." No words could describe better than these the true condition of the great Russian's mind when the scales had fallen from his eyes, and he realized in what a vain show he had been walking. Peace came to him through his suddenly awakening to a sense of the vastness of the life of humanity, and his sudden re- solve to take refuge in it, and, as far as possible, to make its thoughts and feel- ing his own. The lesson in all this is obvious, and it is in direct line with our remarks in a previous number under the head of "The Domain of Science." There is a science of life. There is a way of regarding our relations to the world at large which is true; and, unfortunately, there are many ways of regarding them which are false. There are thoughts, tempers, dispositions, habits, that make for soundness both of mind and body, and there are others in great variety that make for unsoundness. There are certain normal conditions of existence determined by the whole course of human evolution ; and these can not be too widely departed from, under the guidance of purely individual feelings, without serious danger. The work of placing life on a sound basis may be begun at any time, though early is in- deed much better than late. It is all a question of seeing things in their right relations and acting accordingly — all a question of extending the domain of sci- ence from biology and physiology to soci- ology and individual conduct. Rightly read, Tolstoi's " Confession," though it mentions science but disparagingly, should be a great help in this direction. It certainly contains a grave warning against the tyranny of the passions and the utter hollowness of much that passes for literature and philosophy. THE LAND QUESTION. It is almost needless to direct atten- tion to the letters on the land question published in this issue, as the names of certain of the writers would alone create interest in the discussion. Mr. Spencer, unfortunately, has been for some time in a state of health that almost wholly incapacitates him for the labor of the pen ; and, though he has given us two very interesting letters, most readers will feel that he has hardly done full justice to his own position. He has confined himself to the criticisms of Prof. Huxley, and passed unnoticed those of Mr. Greenwood and Sir Louis Mallet. Had he possessed his old-time fire and energy, he would probably have dealt with all his critics in a manner that would have left little to be desired ; we may be sure at least that he would have considered fully and fairly all their objections to his views, and would have given any necessary explanations in that spirit of candor which has always dis- tinguished him. 412 THE POPULAR SCIENCE MONTHLY. It will be noticed that Mr. John Laidler, " bricklayer," is disposed to be severe upon Mr. Spencer for having in part abandoned the views expressed by him as long ago as the year 1852, in his work on " Social Statics." It is hardly worth while, however, to be a philoso- pher if a man can not mature and, if necessary, modify his views as he ad- vances in life and gathers the fruits of experience and reflection. Mr. Spencer long ago recognized that in his " Social Statics " he had expressed himself some- what unguardedly on the land question; and he has refrained for many years from giving any currency to his earlier opinions on that subject. Had his health permitted, it is not improbable that he would have taken some recent occasion for reviewing the whole question, and giving the world the benefit of his latest thought. As it is, he is obliged to con- tent himself with indicating the germ of truth in his former views, and the modifications and safeguards he would now attach to the enunciation of the general principle which they em- bodied. Mr. Frederick Greenwood, who par- ticipates in the discussion, undertakes to point a serious moral, to the effect, namely, that philosophers should be careful how they scatter abroad ideas which may serve as the seeds of revo- lution. The caution reminds us of a famous one given by St. Peter to St. Paul, some of whose writings, the for- mer apostle thought, " the unlearned and the unstable" might "wrest to their own destruction." It was St. Paul, however, with his bent toward philosophy, who moved the ancient world to embrace Christianity. What his critic did in that direction is not very conspicuously recorded on the page of history. Mr. Spencer has labored hard to rationalize the thought of his age, to bring the minds of men into contact with the laws that — whether we recognize them or not — govern hu- man life ; and if, by some, his teachings are misunderstood and misapplied, we must judge of his total influence, not by such cases, but by the whole volume of mental activity that owes its origin to his writings. The general impression which the controversy will leave on the minds of most readers will be, if we mistake cot, that the land question is a good one to leave alone — at present. Not that there are not many abuses connected with the tenure of land waiting to be corrected ; but that the correction of such abuses can best be accomplished without raising the fundamental ques- tion as to whether land can or can not be held by as good a title as chattel property. In this country, a few years ago, we had a slight wave of excitement in connection with the theories pro- pounded in Mr. George's " Progress and Poverty " ; but the conviction has been strengthening, we believe, in most thoughtful minds that, plausibly and eloquently and earnestly as Mr. George has presented his ideas, their adoption could only lead to social and political confusion. The world at large will be better when men individually are bet- ter; and social justice will reign when individual justice reigns. The land re- quires to be appropriated to and by in- dividuals in order that the best and most profitable use may be made of it ; but it does not follow that the individ- ual occupier should act the part of a tyrant toward his fellow-men. A man may do that without owning a foot of land. Every man who follows a gain- ful trade or profession has an interest in the land, seeing that those who own and till it, own and till it for him to the extent of the demand expressed by his wages or emoluments. The world wants justice and wants it now ; but it would be a poor inauguration of justice to turn title-deeds to which society has given every possible sort of sanction into waste paper, and virtually confiscate the honest earnings, invested in land, of millions of honest men. LITERARY NOTICES. 4>3 THE TWENTIETH BIRTHDAY OF "NA- TURE." " Nature," now accepted as the foremost scientific journal in Europe, signalizes the beginning of its forty-first volume by reviewing its own career and the advancement of science during the twenty years that have elapsed since its first number was issued, in No- vember, 1869. It came forward with- out obtrusive advertising, and without making any promises other than what was implied in the statement in Prof. Huxley's introductory article that its aim would be " to mirror the progress of that fashioning of herself in the mind of man which we call the progress of science." It now claims, with a justice that all its readers will recognize, that it "has not disappointed the hopes of its founders, nor failed in the task it undertook." Its pages fairly reflect the aspects which scientific discussion has assumed from year to year ; and every established conclusion has been suitably noticed in them as it gained the right to claim attention. The reader can turn to its columns for facts bearing on all matters of interest of this kind, in the assurance that he will find them there. " Nature " has been able to accomplish this purpose, it says, by enlisting the co-operation — in contributions, and by advice and suggestion — of the leaders in all branches of research, and by show- ing its desire to be for the good of sci- ence and the promotion of knowledge — regarding these as of more impor- tance than journalistic success. While its most prominent function has been to present at first hand the results of the work of these men, it has not disregarded the laity of science. Be- sides taking pains to present its profes- sional articles in a form acceptable to the great body of unlearned inquirers, it has in its correspondence department given them a free parliament for discus- sion. Making itself a faithful mirror of scientific thought, it speedily gained favor among English readers; extended its reputation abroad ; and became the one journal indispensable to students in every branch and every land. Its record of the achievements of science during its lifetime, though con- sisting only of the briefest mentions, is a large one, and includes such facts as the establishment of the Darwinian theory, the periodic law in chemistry, the deter- mination of a relation between electrici- ty and light, the progress of bacteriolog- ical investigation, the advance of spec- troscopical discovery, the vast expansion of physiological research, and many other matters of hardly inferior moment. In all these achievements English inves- tigators are exhibited as among the most active, solid in work, and thorough in inquiry; and none have been more sa- gacious than they in generalization and in applying principles to practice. Not the least important of the results is the education of a generation who have suf- ficient knowledge of science to recog- nize its importance and give it its true position ; so that, when now it points out a new field of inquiry or asserts a new principle, it has no longer apolo- getically to face suspicion and hostility, but meets a friendly and helping public. LITERARY NOTICES. Recent Economic Changes and their Ef- fect upon the Production and the Dis- tribution of Wealth, and the Well- Being of Society. By David A. Wells, LL. D., D. C. L. New York : D. Apple- ton & Co. Pp. 493. Price, $2. Two years ago Mr. Wells contributed to " The Popular Science Monthly " a series of articles entitled " Recent Economic Disturb- ances." They elicited so much comment and discussion that the author now presents them as a book. In so doing he has brought his record of fact down to date, and extended his review so as not merely to treat the economic derangements which date from 1873-'74, but to include the economic his- tory of the past three decades. In comparing the present earnings of la- bor and assets of capital with the figures for 1860, Mr. Wells shows that the economic 4H THE POPULAR SCIENCE MONTHLY. advance of the last thirty years has been lit- tle short of revolutionary. Science applied to field and farm, mill and factory, ship and railroad, has enormously increased the effi- ciency of labor. Hence the remarkable rise in wages, and the correlative fact of the fall of prices which makes a dollar exchange- able for more food and clothing than ever. Although the fortunes of men have been steadily improving, heightened sensibility, progress in social ambition, all that goes to raise the standard of living, have kept pace with the increase of popular luxury and refinement. Then, too, the blessings of industrial evolution, though general, have not been universal ; and in considering its inci- dental pains and penalties Mr. Wells is both candid and sympathetic. He notes how handicraft skill is rendered valueless as ma- chinery supersedes trade after trade. Old- time shoemakers now only get cobbling to do, and the tinsmith who once made all the paraphernalia of the kitchen is to-day no more than a tinker. Minute subdivision of labor reduces an operative to a mere tooth on a wheel ; disrupted from it by an untoward accident of trade, he is of little more worth than a bit of scrap-metal. In manufactures and commerce modern exigencies demand a discipline which almost completely effaces in- dividuality : both employers and workmen are subordinated as parts of a vast and complex enginery. In undergoing the painful and costly readjustments enforced by new econo- mies, capital and labor have been partners in distress, and labor has not suffered more than capital. The increase in the average man's wealth has been partly at the expense of certain unfortunate classes of capitalists. While one set of farmers are being enriched by the rise in the value of Dakota lands, another set in France and England are be- ing impoverished by the cheapness of Dako- ta wheat. The Suez Canal, in shortening the route between Europe and the East, ef- fected a saving in freights greatly to the ad- vantage of consumers of tea, silk, cotton, and spices : it also threw into idleness a vast fleet of ships adapted to the voyage around the Cape of Good Hope, and ruined a lengthy chain of interests vested in things as they were. The discovery of excellent coal and iron-ore near together in Alabama cheapens iron, but it extinguishes furnaces in the Northern States built at enormous outlay, and leads to the abandonment of large found- ry properties in New York and New England. Every new machine and process, while it en- riches the community, entails loss on indi- viduals for expensive plant which must go to the scrap-heap. While Fortune in the economic world has in the main been prodigal of her gifts, those upon whom her lash has fallen very natu- rally demean themselves differently from those upon whom she has smiled. While the cultivation of inconspicuousness on the part of millionaires is far from uncommon, those who have seen their possessions melt away in the discarding of old machinery, old methods, and old routes, make loud com- plaint. Of equal loudness is the alarm vent- ed by those who have reason to fear loss through the supersedure of their property as Science marches on. This complaint and this alarm have been so sustained as to cre- ate an exaggerated impression of the evils economic progress brings in its train. Left to themselves, economic forces would merge the world into a single competitive field, the markets of which would be supplied only from the sources where capital and labor could work to most advantage. The redis- tribution of populations and employments which this would entail is a price a majority of civilized nations refuse to pay : its inci- dental loss and misery impi'ess their imagina- tion too deeply. Yet the choice is between this shunned evil and a greater. Vastly more is lost by declining to enjoy the gifts new knowledge stands ready to confer, in de- clining the harvests labor can reap when free to sow and till where natural conditions most favor it. Nothing in Mr. Wells's book is more impressive than the picture he draws of European nations severally striving by force of law to overcome some defect in soil, climate, position, or skill. France, for ex- ample, excludes American wheat as far as she can by a high duty. Does she not there- by injure the population of bread - eaters more than she eases the lot of a few wheat- growers ? The vanity of attempts to jug- gle with inexorable Nature has imperiled interests higher than those of wealth ; these attempts have checked the good-will which was springing up as trade united interna- tional interests and foreigners were ceasing LITERARY NOTICES. 415 to be strangers. In making battlefields of their custom-houses, ethnic dislike has, doubt- less, served to stimulate commercial jealousy among the people of Europe, and this in its turn fans the animosities which endanger peace. While their neighbors have been indulg- ing in costly tariff reprisals upon each other, the British, Dutch, and Swiss, firmly holding to freedom as the right rule of trade, have, perhaps unconsciously, borne testimony to economy and ethics being fundamentally one. Theirs has been the chief progress not only in wealth, but education, the abatement of crime, the lengthening of life. Russia, at the other extreme of fiscal policy, aiming at nothing short of the prohibition of foreign trade, finds her markets depressed and her treasury depleted. The oblique form of pro- tection known as the bounty system has been tried with results which, as traced by Mr. Wells, must have surprised the experiment- alists. France and Germany, in artificially stimulating the production of beet- root sugar, have only succeeded in taxing themselves heavily to provide their chief rival in manu- factures, Great Britain, with an important raw material at less than cost. The British industry in jam and sweets, expanded by cheap sugar, now employs more people than those needed to refine the sugar consumed. The general fall in prices during the re- cent past has been a source of much embar- rassment and perplexity in the world of com- merce. Among the theories proffered in its explanation that of the bimetallists has been prominent, and Mr. Wells riddles it thor- oughly. He shows that whereas the cost in labor of producing gold has varied but little for ages, silver during this generation has been discovered in prodigious deposits ; therefore any legislative attempt to main- tain a hard-and fast relation between the values of gold and silver must be vain. He points out that the gold reserves in the banks of the world are to-day, pro- portionately to capital, larger than ever. Furthermore, that the demand for gold con- stantly diminishes as banking facilities over- spread the world with their telegraphic trans- fers, clearing-houses, and other devices for the economy of coin. But if it be demurred, Does not a debt incurred, say, ten years ago, require to-day more wheat or iron for its satisfac- tion than the sum could have bought when first borrowed ? Certainly, but the wheat or iron represents no more labor now than it did ten years ago, and its increase in quantity stands for the new efficiency which applied science has bestowed on toil. Let the fall in the rate of interest be noted as evidence that, among sufferers from reduced pay, capital ranks as chief. In every page, whether considering the eight - hour movement, the transportation problem, the gigantic cost of protecting American iron and steel for a decade, or any other of the manifold lines of his inquiry, Mr. Wells's analysis is transparent and im- partial. In tracing the bearing of econom- ic development on the welfare of man he rises by breadth of mind and sympathy to the dignity of a philosopher. A Popular Treatise on the Winds. By William Ferrel, Ph. D., late Professor and Assistant in the Signal Service. New York: John Wiley & Sons. Pp. 505. Price, $4. Several essays bearing upon the mechan- ics of the atmosphere have been published by Prof. Ferrel at various times since 1856, but, as they were of a very mathematical character, they were adapted only to those well-trained in mathematics. The present volume is of a more popular nature, although the simpler mathematical operations involved in the presentation of the subject are re- tained. After a general description of the constitution and nature of the atmosphere, the effect of the earth's rotation in the dy- namics of the atmosphere is explained, the general circulation of the atmosphere is de- scribed, and its climatic influences are pointed out. This circulation is shown to agree with the laws governing the movements of gases and vapors acted upon by heat and other forces. The rest of the volume is devoted to descriptions of the various kinds of winds, monsoons, land and sea breezes, cyclones of several varieties, and tornadoes, and explana- tions of their special causes. Thunder-storms water-spouts, hail-storms, and cloud-bursts, with various other allied phenomena, are also explained. The author offers his book to gen- eral readers interested in the subject, and to lecturers on meteorological subjects be- fore college classes or other audiences. 416 THE POPULAR SCIENCE MONTHLY European Schools. By L. R. Klemm, Ph. D. International Education Series, Vol. XII. New York : D. Appleton & Co. Pp. 419. Price, $2. Rarely has a book for teachers appeared containing so much that can be used in the school-room. It is not a ponderous and re- pulsive budget of statistics of school attend- ance, examination marks, illiteracy, etc., with courses of study and descriptions of depart- mental machinery. It is an account of the notable features observed during a trip of nearly a year among the educational institu- tions of the continent of Europe, or, as the author describes it in his sub-title, " what I saw in the schools of Germany, France, Aus- tria, and Switzerland." The first device de- scribed in the book is an expedient which was employed by a teacher in Hamburg, and is called by the author " a master stroke." A stupid boy could not see that the differ- ence between plus six and minus ten is six- teen. The master explained the problem and illustrated it with marbles, but in vain. Finally, he cast his eyes about the room, and they fell upon the thermometer. In a mo- ment he had this before the pupil's eyes, and readily made him comprehend that the dif- ference between 6° above zero and 10° be- low zero is 16°. A box of movable letters, a board with a slit in it through which let- ters making words are shown, a scheme for ventilation, a mode of teaching home geog- raphy, and a sketch of an efficient city school system, follow within the compass of a few pages. Methods of teaching drawing in dif- ferent schools are described in several parts of the volume, and singing, knowledge of nature, mensuration, and language are only a few of the subjects dealt with. A notable section is that devoted to " a separate school for dullards," an idea which started in Rhen- ish Prussia at Elberfeld and has spread to other cities. This is not a school for idiots, but is intended for those unfortunate chil- dren whose dullness acts as a drag on their classes and brings ridicule and discourage- ment upon themselves. Here they receive patient instruction, and learn much more than they could in schools adapted to bright- er pupils, while the latter are freed from im- pediments to their progress. The account of girls' industrial education at Cologne, comprising knitting, crocheting, embroidery, weaving, sewing, lace-making, cutting out garments, mending and patching, and accom- panied by drawing, will be found interesting and suggestive. It is impossible to mention here all the subjects touched upon in this book ; they cover a wide range, and each is presented in sufficient detail to give a definite idea of the method employed. The style of the book is clear and enthusiastic; the lan- guage is simple and, in humorous passages, even colloquial. It is a very readable vol- ume— one which the teacher can take up at odd moments even when tired, and study without a sense of laboring. A notable feat- ure of it is its abundance of illustrations, there being five hundred and twenty-three figures showing drawing models and outlines, articles used in teaching, plans of school- buildings, maps made in teaching local geog- raphy, articles and patterns made in manual training schools, etc., etc. The Journal or Physiology. Vol. X. Ed- ited by Michael Foster, M. D., F. R. S. Cambridge (Eng.): Cambridge Scientific Instrument Company. Pp. 576. Thirty- three Plates. Price, $5 a volume. There are two papers in this volume on " The Regulation of Respiration," by Henry Head. The first details experiments made to ascertain the effects on breathing pro- duced by dividing the vagi, by altering the volume of the lungs, by artificial respiration, and other means. Many observations were also made on the forms which the apncea pause produced by artificial respiration as- sumes under various conditions. Nine plates of curve tracings accompany this paper. The theoretical conclusions from these experi- ments are embodied in the second paper. C. A. MacMunn contributes an account of experiments from which he infers that " bili- rubin and biliverdin are produced in the liver mainly from effete haemoglobin ; these are acted on in the small intestine by the digestive and putrefactive ferments, and some, at least, changed into simple metabo- lites like the urobilin-like substance of bile." Stercobilin, formed in the intestines from derivatives of bile and haematin, may be taken up and excreted in the urine as patho- logical urobilin. Some " Observations on Hu- man Bile obtained from a Case of Biliary Fistula," by S. M. Copeman and W. B. Win- LITERARY NOTICES. 417 ston, appear in another number of this vol- ume. Regarding " The Nature of Knee- jerk," W. P. Lombard maintains that the reflex theory readily explains the intimate dependence of the phenomenon upon the spinal cord, and that the time argument against it is inconclusive, owing to our mea- ger knowledge of reflex times in general, while the peripheral theory is untenable. The third number of this volume is devoted to a paper on " The Relation between the Structure, Function, Distribution, and Origin of the Cranial Nerves ; together with a The- ory of the Origin of the Nervous System of Vertebrata," by W. II. Gaskell. It is ac- companied by five plates. W. D. Halliburton contributes the results of chemical analysis of a number of specimens of cerebro-spinal fluid, and, together with W. M. Friend, the results of an examination of the stromata of the red corpuscles. A second paper on " The Electrical Organ of the Skate," by J. B. San- derson and Francis Gotch, contains obser- vations as to the nature of the normal reflex process by which the electric organ is dis- charged, and the measurement of the electro- motive force of the response of the organ to a single excitation. J. N. Langley reports further investigations upon the salivary glands in two papers, one dealing with " The Physiology of the Salivary Secretion," the other with " The Histology of the Mucous Salivary Glands, and the Behavior of their Mucous Constituents." L. C. Wool bridge, in a brief paper entitled " The Coagulation Question," argues against certain views of Dr. Halliburton. W. II. White contributes " Further Observations on the Histology and Function of the Mammalian Sympathetic Ganglia," a previous paper having been pub- lished in No. 2, Vol. VIII of the "Journal." An extended paper on " The Innervation of the Renal Blood- Vessels," by J. Rose Brad- ford, deals with the courses of the vaso-con- strictor and vaso-dilator fibers, with the phenomena following excitation of the splanchnic nerve and of the peripheral end of the divided vagus, also with the reflex phenomena of the renal vessels. T. W. Shore and II. L. Jones publish a descrip- tion of " The Structure of the Vertebrate Liver," approaching their subject from the side of comparative anatomy. G. N. Stew- art presents a detailed account of a research vol. xxxvi. — 27 on " The Stimulation Effects in a Polarized Nerve during and after the Flow of the Polar- izing Current." C. S. Sherrington and C. A. Ballance, in a paper on " Formation of Scar- Tissue," give the record of their investiga- tion as to whether the colorless corpuscles of the blood are the source of the new tissue which the inflammatory process produces. Hygiene and Public Health. By Louis C. Parkes, M. D. Philadelphia : P. Blakis- ton, Son &Co. Pp. 471. Price, $2.50. Substantially the whole field of sanitary science is brought within a moderate com- pass in this book. Water, removal of refuse, ventilation, warming, lighting, climate, build- ing-sites, food, exercise, and clothing, all re- ceive due attention from the hygienic side. A chapter on the prevention of communica- ble diseases has been included, also one on vital statistics. The book is intended for both the physician and the layman. Its language is simple enough, so that no tech- nical knowledge is needed to understand it, though there are some tests and calculations included which the average layman will not make use of for himself. Numerous exam- ples and illustrations are introduced in order to assist the physician in his public health work. The author deems the chapter on the removal of refuse rather long in proportion to the book, but gives as his reason for going so much into detail that apparently trivial defects in house-drainage, which are liable to be overlooked without thorough knowledge, are often the cause of the most severe outbreaks of disease. The volume is lettered on the back, "Practical Hygiene, Parkes," but the intending buyer should not confuse the book with the "Manual of Prac- tical Hygiene" by the late E. A. Parkes. A First Book in American History. By Edward Eggleston. Illustrated. New York: D. Appleton & Co. Pp. 203. Price, 70 cents. The story of America is told by Mr. Eggleston in this book in a simple and vivid style. The requirements that he has had in view while preparing it arc that an element- ary book must, for those whose school-life will be short, give the leading facts of the whole field to be studied, and must not force upon those who are to follow it with an advanced work matters which will have to be restudied 418 THE POPULAR SCIENCE MONTHLY. later. Furthermore, a beginners' book ought, before all things else, to be interesting. " The main peculiarity of the present book," says the author, " is that it aims to teach chil- dren the history of the country by making them acquainted with some of the most illustrious actors in it. A child is interested, above all, in persons. Biography is for him the natural door into history. The order of events in a nation's life is somewhat above the reach of younger pupils, but the course of a human life and the personal achieve- ments of an individual are intelligible and delightful." By this means, also, the young American gets distinct pictures of the careers of the great men of his country. It is easy, moreover, in a history of the biographical type, to adopt the modern style of describing the life of the people in former times, as well as the progress of public events. The author is convinced that the lamented lack of moral teaching in our schools can be largely supplied by the inspiring examples found in the careers of our great men. The author has availed himself abundantly of the aid of pictures in giving the pupil a vivid conception of the narrative. No precipe mode of studying the book is prescribed, but brief suggestions for a topical recitation are appended to each lesson. The book is well adapted to be used as a class reader, and several school superintendents have already declared their intention of employing it in this way. The pictures are numerous and bear the signatures of some of the most emi- nent illustrators in America. The maps arc bird's-eye views, and one, designed to show the territorial growth of the United States, has the successive additions of territory printed on successive pages, the blank parts of which are to be cut out. Chemistry: General, Medical, and Phar- maceutical. By John Attfielp, F. R. S., etc. Twelfth edition. Philadelphia: Lea Brothers & Co. Pp. 770. Price, $3.25. This substantial volume is adapted to be the life-long companion of the pharmacist or physician — a manual of instruction in his student days and a work of reference in his business or professional practice. The au- thor expressly disclaims the recognition of any such varieties of the science as medical and pharmaceutical chemistry, and uses these terms only to indicate that he illustrates the principles of chemistry by those facts of spe- cial interest to the followers of medicine and pharmacy. " From other chemical text- books," he states in the preface, " it differs in three particulars: first, in the exclusion of matter relating to compounds which at present are only of interest to the scientific chemist ; secondly, in containing more or less of the chemistry of every substance recognized officially or in general practice as a remedial agent; thirdly, in the paragraphs being so cast that the volume may be used as a guide in studying the science experimentally. The order of subjects is that which, in the au- thor's opinion, best meets the requirements of medical and pharmaceutical students in Great Britain, Ireland, America, India, and the English colonies." A few leading prop- erties of the elements arc first given, some of the fundamental principles of the science are next stated, and then the properties and relations of the elements and the compound radicals are presented in detail, attention being directed to those qualities on which analysis and synthesis depend. The chem- istry of the carbon compounds is next con- sidered. Practical toxicology and the chem- istry of morbid physiological products then receive attention. The concluding sections form a laboratory guide to the chemical and physical study of quantitative analysis. In the appendix is a long table of tests for impu- rities in medicinal preparations ; also a short one of the saturating powers of acids and alkalies, designed for use in prescribing and dispensing. In his arrangement of the radi- cals, the author " has preferred to lead up to, rather than follow, scientific classification," for the reason that systems of classification give " undue prominence to one set of rela- tions and undeserved obscurity to others." The metric system is alone used in the sec- tions on quantitative analysis ; in other parts of the volume avoirdupois weights and impe- rial measures are employed. Numerous ety- mological notes are scattered through the book. A list of questions follows each sec- tion. The present edition contains what al- terations and additions have become neces- sary since the appearance of the eleventh in 1885. The work now includes the whole of the chemistry of the United States Pharma- copoeia and nearly all that of the British and LITERARY NOTICES. 419 Indian Pharmacopoeias. The chief new feat- ure is the extended section on organic chemis- try. By means of the index of fifty-six pages all the information in this comprehensive vol- ume is made readily accessible ; eighty-eight cuts show the forms of apparatus needed for the operations described. Strength : How to Get Strong and Keep Strong By Richard A. Proctor. Lon- don and New York : Longmans, Green & Co. Pp 178. Price, 75 cents. The scope of this book is well set forth in the following sentences from the introduc- tory pages : " Men, and women too, though they may have no occasion to acquire skill in athletic exercises, have great occasion to possess sound bodies, unless they are pass- ing absolutely useless lives, when they may do as they please so far as their value to the community is concerned. ... I propose in this little treatise to show how, by devoting a few hours weekly to well-arranged exer- cises, this end can be attained. No violent exertions are necessary, no difficult feats need be attempted, no special form of exer- cise need occupy much of the time and atten- tion." Successive chapters are devoted to the description of exercises, many without apparatus, the others with only simple ap- pliances, adapted to the expansion of the chest, and to the development of the mus- cles of the chest, abdomen, loins, arms, and legs. There are also chapters on reducing fat, the adapting of exercise to advancing years and to weakness, some " notes on row- ing," and directions for learning to swim. A comparison of "Nature's Waist and Fash- ion's " is included, to which a lady contrib- utes her experience in discarding the corset and adopting the divided skirt. The volume is illustrated with figures of classic statuary and of gymnastic apparatus. The Story of the Bacteria. By T. Mitch- ell Prcdden, A. M. New York : G. P. Putnam's Sons. Pp. 143. Price, 75 cents. Everybody has heard of bacteria ; many with a conscientious desire to keep informed upon the progress of science have undertaken to read up aboit them ; and a large propor- tion of these inquirers must have retreated baffled from the task. But if those who have been discouraged by the technicalities of the learned treatises on micro-organisms would still like to know what the bacteria are and do, and how they are cultivated and examined , they can find out very pleasantly by reading Dr. Prudden's simple and fasci- nating " Story of the Bacteria." The au- thor describes the chief forms of bacteria, and several kinds which are curious from their color, power of emitting light, etc. He then tells how they act in producing surgical diseases, consumption, and typhoid fever, and what means are taken to repel their attacks. He also sets forth what is believed in regard to the relations of bacte- ria to Asiatic cholera, diphtheria, pneumonia, scarlet fever, etc. — diseases in which the ac- tion of the germs is less easily demonstrable. He points out, further, how impure food, air, water, and even ice may serve as sources of bacterial infection ; and in conclusion gives the layman an intelligent view of the pres- ent standing of investigation in this field. This little book shows how perfectly a sci- entific subject may be freed from perplexing technicalities, and may well serve as a model of popular scientific writing. According to the Report of the Commis- sioner of Fish and Fisheries for 1886 (United States Fish Commission), the work of the year included explorations along the eastern coast of North America from the Straits of Florida to Newfoundland, in order to ascer- tain the winter range and habits of the mackerel, menhaden, blue-fish, and other important food fishes that resort to the eastern shores of the United States in the warmer months. Observations of the tem- peratures and densities of the water were made continuously at all the stations of the Commission, from the Commission's vessels, and at many light-houses and light-ships. The schooner Grampus, intended as a mod- el for off-shore fishing smacks, and also containing a well for the conveyance of live fishes, was completed and added to the fleet of the Commission in this year. The dis- tribution of the eggs and fry of food fishes was continued. The papers appended to the report comprise a comprehensive account of "The Sea Fisheries of Eastern North America," by the late commissioner, Spen- cer F. Baird ; " A Review of the Flounders and Soles of America and Europe," by 4-20 THE POPULAR SCIENCE MONTHLY. David Starr Jordan and David Kop Goss ; a review of the Seiceniclce, by Prof. Jordan and Carl IT. Eigenmann ; a paper on inter- nal parasites of fishes, by Edwin Linton ; and a report on Medusae, by J. Walter Fewkes, all but the first of these being illustrated. A large number of reports from the vessels and stations of the Commission are printed, and the following papers from foreign sources are included in the volume : " On the Fish- cultural Establishments of Central Europe," by E. Bettoni and D. Vinciguerra ; " Chemi- cal Composition of Food Products," by P. Kostytscheff ; " Cases of Poisoning caused by Spoiled Codfish," by Dr. E. Mauriac, and " Notes on the Norwegian Fisheries of 1885," by A. N. Kiaer. There is also a list of sta- tions at which dredgings have been made in the Atlantic and Arctic Oceans from 1867 to 1887, by Sanderson Smith. The list is accompanied by five charts. A translation of a series of essays by the Baroness Marenholtz - Buelow, setting forth Froebel's educational system, has been pub- lished under the title The Child and Child- Nature (Bardeen, $1.50). It describes the nature of the child, his needs, and the effects of training upon him. An account of Froe- bel's method is given, and this is followed by some of the exercises and translations of the songs which he devised for teachiug the child's relations to nature, to mankind, and to God. A bibliography of Froebel is ap- pended, and an index has been added to the American edition. Dr. R. von Krafft-Ebing's Experimental Study in the Domain of Hypnotism has been translated into English by Charles G. Chad- dock, M. D. (Putnam, $1.25). It is an ac- count of a case which has excited much interest in Gratz, and comprises the prelimi- nary history of the patient, a record of the course of her hystcro-epileptic attacks, and a transcript from Prof. Krafft's daily note- book of hypnotic experiments upon her. Evolution of the Electric Incandescent Lamp, by F. L. Pope (H. Cook, Elizabeth, N. J.), is a collection of extracts from rec- ords of courts and of the Patent - Office, newspaper files, and transactions of scien- tific societies bearing upon the question whether Edison or Sawyer and Man deserve the credit for the employing of a carbonized filament of organic material in the incan- descent lamp. The book is illustrated with cuts of apparatus. A beginner's text-book of Iron and Steel Manufacture has been prepared by Arthur H. Hiorns (Macmillan, $1), designed to give a knowledge of the principles underlying the processes of this industry. In the early chapters the substances used or produced in smelting are defined, the ores of iron are de- scribed, and the chemistry of the subject is explained. Then follow descriptions of the usual methods of extracting and refining the metal, and of the furnaces, hammers, and rolls employed in these operations. Iron casting, tinning, and galvanizing are also described. The processes in the production, tempering, and testing of steel are set forth in like manner. Questions are appended to each chapter for the use of students. No. 96 of Van Nostrand's Science Series is on Alternate-Current Machinery, and com- prises a paper read by Gisbert Kapp before the Institution of Civil Engineers, London, with the discussion upon it. Of the appa- ratus which may be properly included under his title, the author deals especially with alternators, transformers, and motors. The volume is illustrated with forty-three dia- grams. Since the first edition of the Manual of Assaying Gold, Silver, Copper, and Lead Ores, prepared by Walter Lee Brown (E. H. Sargent & Co., $2.50), was noticed in this magazine, the book has been increased from 318 to 487 pages. Other changes as given by the author are, " the stating of all charges in assay tons, grammes, and grains ; detailed charges in the scorification process ; full notes on the colors and appearances of the scorifiers (with a colored plate) and cupels after work ; the expansion of the crucible process from nine to almost ninety pages; more complete articles on the assay of gold and silver bullion, and the volumetric analy- sis of copper ores ; and, finally, the issuance of the book in flexible covers." The present (third) edition is but little changed from the second. The little book by the late Walter Bage- hot, embodying a Flan for Assimilating the English and American Money, first pub- lished in 1869, has been reissued in view of an expected revival of interest in the LITERARY NOTICES. 421 subject (Longmans, 75 cents). The author names, as trifling advantages of an interna- tional coinage, the convenience of travelers, facility in the exchange and transmission of coin, and in the comparison of monetary statistics. What he deems the one great advantage of such a money would consist in making identical the monetary language of the trade circulars of different nations. He believes that an international coinage should be founded on a single standard, have a high gold unit, have decimal divisions, and do no violence to national jealousies. Several inter- national unit coins have been proposed — a twenty-five-franc piece, the English sover- eign, a piece weighing ten grammes, and a ten- franc piece — but Mr. Bagehot points out ob- jections to them all. The scheme which the author proposes is to unite the two great Anglo-Saxon nations upon a system of coins, by changing the sovereign from 960 to 1,000 farthings, or £1 0s. 10c/., which is almost identical with the American half-eagle. He believes that Germany and the Latin Union would in time adopt the Anglo-American money. In his essay on Involuntary Idleness, read before the American Economic Association, and now published as a book (Lippincott, $1), the author, Mr. Hwjo Bilgram, searches for the cause of lack of employment. He first examines the relation of capital and interest to labor, and obtains the inference that " a close relation exists between the economic cause of involuntary idleness and the law of interest." The author states that there is a tendency for the industrial class to drift into bankruptcy, and for money to accumulate in the hands of the financial class, thus depriving the channels of com- merce of the needed medium of exchange, and causing stagnation of business and dearth of employment. The law of interest is then evolved by an analysis of the mone- tary circulation between the debtors and creditors. From this analysis is drawn the inference that " an expansion of the volume of money, by extending the issue of credit- money, will prevent business stagnation and involuntary idleness." The Teacher's Manual of Geography, by Jacques W. Rcdway (Heath, 55 cents), con- sists of suggestions to teachers on out-of- door lessons for young pupils, the use of pictures and models, recitation, map-making, geodesy, hydrography, meteorology, history in geography, and boundary lines. Simple ideas of form, size, color, and locality are suggested to be presented to the youngest children in preliminary oral work. The tend- ency of the book throughout is to lead the teacher to give pupils a practical, compre- hensible knowledge of the earth's surface, to correct popular errors, and to escape from traditional ruts. A list of books for geo- graphical reading is appended. A series of Topics in Geography, pre- pared by W. F. Nichols, for the use of his own schools, has now been published (Heath, 55 cents). The author states that his aim has been to make the study of geography more valuable, while shortening the time usually spent upon it. To this end he shows what to teach and what to omit, giving first a brief outline for a study of any continent based upon slope, and furnishing topics, to be taken up after this, which cover all that it is desirable to learn. Other features of his treatment are the sparing use of statis- tics, the combination of language with geog- raphy, and the making prominent of natu- ral objects and wonders, which are always interesting to pupils. The course of study is graded. By permission, Prof. Redway's list of books for geographical reading is included. The Nursery Lesson Book, by Philip G. Hubert, Jr. (Putnam, 75 cents), is designed as a guide for mothers in teaching young children. It comprises fifty lessons, each conveying simple and progressive instruc- tion in reading, writing, arithmetic, drawing, and singing. It contains one hundred illus- trations in outline and sixteen songs set to music. The page is large, the margins gen- erous, and the general appearance of the book is attractive. The life and labors of Vitus Bering, the Discoverer of Bering Strait, have been re- corded in Danish by Peter Lauridsen, and an English translation by Prof. Julius E. Olson is now published (Griggs, $1.25). Bering was a Dane, who took to the sea in early life, and at the age of twenty-two joined a Russian fleet as a sub-lieutenant. This was during the period of Russia's rapid advancement under Peter the Great. In 1724 Bering, then a captain, was appointed 422 THE POPULAR SCIENCE MONTHLY. chief of an expedition to determine whether Asia and America were connected by land. The expedition went overland through Sibe- ria to Kamchatka, where ships were built and the explorations begun. Bering reached the strait that bears his name, and thus proved that Asia and America were sepa- rated by water. Soon after his return he proposed a second expedition to chart the northwestern coast of America, then an un- known land, and the northern coast of Sibe- ria. This should lead to the establishment of trade with the American colonies, and also make known a way by water from Rus- sia ai'ound to Japan. Bering reached the coast of Alaska in 1741, and died on the way back. For a long time jealousy dis- credited his results, and the chief object of the present volume is to establish the value of his discoveries. The book also tells the story of the obstacles which he overcame in his expeditions. It is accompanied by two folded maps, and has an introduction by Lieutenant Frederick Schwatka. The literature of cycling has been in- creased by a book bearing the title Cycling Art, Energy, and Locomotion, written by Rob- ert P. Scott (J. B. Lippincott Company, $2). It is largely devoted to explaining the me- chanical principles involved in the action of the cranks, wheels, springs, bearings, gears, etc. It includes also brief discussions of the injuries charged against cycling, the bi- cycle for ladies, English and American work- manship in cycles, aluminum in cycle con- struction, and the application of steam and electricity to cycles. A second part of the volume comprises extracts from the patent specifications of a large number of veloci- pedes, cycles, and nondescript vehicles, with the inventors' drawings of the machines and riders, and humorous comments by the au- thor. Many of these machines are astonish- ing contrivances, and perhaps none more so than the flying-machine, patented March 5, 1889, which is introduced at the end. PUBLICATIONS RECEIVED. Adams, Mvron.

The American Forestry Association. — The American Forestry Congress at its eighth annual meeting, held in Philadelphia in Octo- ber, changed its name to Association. The meeting was opened with an address by the Hon. Carl Schurz, in which he narrated the difficulties he encountered from the opposi- tion of Congressmen when, as Secretary of the Interior, he endeavored to protect the forests on the public lands against timber thieves. Mr. B. E. Fernow spoke on " Meth- ods of Forestry Reform," and particularly of what lay within the competency of the Gov- ernment. Resolutions offered by Mr. Fernow, recommending the withdrawal of all public forest-lands from sale till a permanent sys- tem of national forest management can bo applied, called out debate. Mr. L. Thompson, a lumberman, argued that it would be con- trary to our national usage and the spirit of our institutions to extend the sphere of Gov- ernment control over interests that have been hitherto successfully managed by private en- terprise ; that the forests would be better protected by selling the land to citizens than by putting them under the management of office-seekers and politicians. Colonel Ed- gar T. Ensign held that where large water- sheds are involved, and the streams are to be used for irrigation, only national control can be made efficient and adequate ; that it is not enough even to leave the matter to indi- vidual States. Mr. Richard J. Bin ton point- ed out the impossibility of adequate super- vision by owners or individual States of riv- ers like those that have their sources in our Western mountain forests. Mr. Fernow's resolutions were adopted. A resolution in favor of removing the duty on lumber wa8 not entertained, for fear of drawing the Asso- ciation into political controversies. Lake Ridges of Ohio. — In the American Association paper of the Rev. G. Frederick Wright on "The Relation of Lake Ridges in New York, Ohio, and Ontario," the ridges in Ohio were described as being four intnum- ber, and standing at elevations above the sea of 775, 720, G90, and 650 feet. They consist of sand and gravel piled up to the height of from five to twenty-five feet, and approximately parallel with Lakes Erie and Ontario, and are evidently old shore lines of the lakes. The problem of how the water could have been kept up to these several levels seems to have been solved with considerable probability by recent glacial investigations. Attention was called to the fact that the ir- regularities of the southern boundary of the glacial region are such that if the retreat of the ice front was with equal rapidity all along its course it would have wholly withdrawn from Lake Erie and western Lake Ontario some time before the ice-dams across the Mo- hawk and the St. Lawrence had been melted away. An inspection of the map shows that two of the most important of these outlets would be, (1) that through Seneca Lake into the Chemung River in New York, and so into the Susquehanna, and (2) that through the Wabash at Fort Wayne, Ind. The heights correspond pretty well with that of the up- 424 THE POPULAR SCIENCE MONTHLY. per and third ridges in Ohio, the upper ridge being probably connected with the Chemung River outlet, and the third with the Wabash outlet. Favoritism at Trinity Honse. — Prof. Tyn- dall published a full account, in the " Fort- nightly Review " some months ago, of the transactions that led him, in 1883, to resign his position as scientific adviser to the Trin- ity House. The case, according to his show- ing, was one of the persistent exercise of per- sonal and political favoritism by the Eoard of Trade in the experiments for determining what were the best lights for lighthouse purposes. In the competition between the quadriform gas-light of Mr. Wighain, a Scotch Irishman, who had the misfortune to be in trade, and the eight-wick oil-lamp of Mr. Douglass, whose brother was connected with Trinity House, the conditions were arranged so as to be more favorable to the latter. The electric light was then introduced into the competitions, and the proposition gradually assumed a form indicating a disposition to crowd Mr. Wickham out ; so that Prof. Tyn- dall came to the conclusion that "if the treatment of the gas invention and its opti- cal adjuncts could be regarded as a fair sam- ple of the treatment of Ireland by England, it would be the bounden duty of every Irish- man to become a Home-Ruler." The evi- dences of partiality becoming more and more prominent in the action of the board and its committee, Prof. Tyndall felt constrained to resign. Two months afterward the com- mittee went to pieces. Prof. Tyndall ob- serves that some of the parties throughout the transactions seemed to think that Ire- land, and not the ships of all nations sailing to its coasts, was the chief beneficiary from the lighthouses. Interesting Fossils of British North Amer- ica.— The Cretaceous fossil plants of Port McNeill, Vancouver Island, as described by Sir William and G. M. Dawson, consist chiefly of dicotyledonous leaves, with a few fruits. Large slabs have been procured, some with perfect specimens of the leaves. There are no ferns or cycads in the collection, and conifers are rare. Among the latter are two species of Salisburia, or gingko, one of which is " a beautiful little form." The exogenous leaves are very numerous, and belong to a number of genera, with at least twenty spe- cies, giving evidence of a very rich and varied forest flora of warm temperate aspect. Sir William Dawson has made an interesting study of the Balanus hameri of the Pleisto- cene of Riviere Beaudette, a species which is still living in somewhat deep water on the Ca- nadian coasts. The specimens under consid- eration were found farther west than any point at which the fossil had been previously ob- served, and are interesting from their remark- able perfection and the large masses which they form. The original attachments of the animals, so far as observed, were on pebbles on the surface of the clay, and, as these afforded space for only one or two indi- viduals, the young were obliged to attach themselves to the old in successive genera- tions. Most grotesque groups were thus formed, which still remain entire. Observa- tions of peculiar varieties of the mussels Mya arenaria and Mya truncata in the mod- ern sea and in the Pleistocene have led the same author to remark upon the interesting feature of " the companionship of these al- lied species in the North Atlantic throughout the Pleistocene and modern periods, and their range of varietal forms applicable to each, according to the conditions to which they have been exposed, along with their contin- ued specific distinctness, and the preference of each for certain kinds of environment ; so that in some places one and in others the other predominates, while this relative pre- dominance, as well as the prevalence of cer- tain varietal forms, might no doubt be re- versed by change of climate or depth." The Cretaeeons Inland Sea. — In the course of two years' study of the northern and eastern terminations of the Texas Cre- taceous deposits, Prof. Robert T. Hill has found that the marine sedimentation of both divisions of the formation was limited" on the north by an older continental shore line, the present remnant of which extends from the Ouachita River, near Malvern and Hot Springs, Arkansas, almost due west through Indian Territory into the Fanhandlc of Tex- as. The whole Cretaceous history, includ- ing the upper and lower systems, can be summed up as two profound subsidences, sep- arated by a land epoch, which have left in POPULAR MISCELLANY. 425 their sediments two great chalk formations. During the second subsidence, which was the deepest in all Mesozoic times, the Atlantic Ocean extended continuously from British America southward around the Appalachian continent. Prof. Hill has begun the publi- cation of a series of illustrations of the pale- ontology of the Cretaceous formations of Texas, in which pictures and outlines of characteristic fossils are given, with letter- press descriptions. The first number thus represents Peden (Vola?) Rocmeri Petero- cera Shumardi, and Crioceras ? (Acayloceras) Texanus — all new species, of the Comanche series, or Lower Cretaceous. An Orthodox Compliment to Darwin. — The first number of the " Cumberland Pres- byterian Pteview" (Nashville, Tenn., Janu- ary, 1889) contains a broad and enlightened article on " Charles Darwin," by Prof. J. I. D. Hinds. The author, whom the company in which he appears attests to be orthodox, looks at Darwin's doctrines on their merits, without regarding their seeming bearing on questions that are equally liable to be mis- understood with those with which the theory of evolution deals. "When a man wins distinction in this world," he begins, " it is customary to condemn him outright if his teaching happen to be in conflict with the consensus of mankind. This is natural, but at the same time very unwise ; since it has thus often happened that theories have been placed under the ban which have afterward been proved true. ... If Darwin found the correct explanation of the phenomena of the organic world, his theory will stand the test of investigation and logic ; if not, it must take its place with other theories which have served their day, and have yielded to better ones ; she must be content to leave the decis- ion to the scientist and the philosopher, and we can certainly have no reason to reject their final conclusion. . . . The Christian, of all men, should have the greatest confi- dence and repose of mind in the face of the investigations of the present day : for, if his religion be true, its foundations can not be shaken ; and, if it be false, he has nothing to lose." Of Darwin's theory, undoubt- edly its first tendency " is toward infidelity and skepticism. But since the world has become familiar with it, and has found that it is simply an attempted explanation of the ordinary course of nature, to be placed side by side with Newton's law of gravitation, Copernicus's theory of the solar system, the nebular hypothesis, and the geological eras of indefinite time, it has ceased to be athe- istic, and is likely soon to become itself one of the arguments of natural theologians." Of Darwin's agnosticism, " his religious views and the changes through which they passed were but the natural outcome of the course of his investigations and studies. He was a pioneer, and could not see the true ethical import of the doctrine which he pro- mulgated. Like many other investigators, he contrasted the ideal of God to which his theories led him with theological dogmas and the prevalent anthropomorphic concep- tions of Deity. His training had been Cal- vinistic, and the freedom which he found everywhere in nature did not accord with the Calvinistic idea of fatality and the arbi- trary action of the supernatural will." Fi- nally, " In truth, let me ask, how much worse is it to have pithecoid ancestors than to be a beast in propria persona ? The great ques- tion with us is, not whence we came, but what we are, what we should be, and what we are destined to be." The Moving Forces of Meteorite Swarms. — An attempt has been made by Mr. G. H. Darwin to apply the kinetic theory of gases to the case of a swarm of meteorites in space. The individual meteorites are analogous to the molecules of the gas, and the mass of gas corresponds, in the author's theory, to the whole solar system. Lockyer and Sir Will- iam Thomson have expressed their conviction that the present condition of the solar system is derived from an accretion of meteorites, but the idea of fluid pressure seems necessary in explaining present forms of equilibrium. The author proposes to reconcile the two theories by showing that the laws of fluid pressure apply to a swarm of meteorites which is condensing to a solid form. The case of an infinite atmosphere of equal- sized meteorites is consfflered, and then the case of meteorites of very different sizes. In the case of a swarm of meteorites condensing under the mutual attractions of its parts, the author shows that the larger meteorites will gravitate toward the center of condensation, 426 THE POPULAR SCIENCE MONTHLY. and that consequently the mean density of the condensed mass will decrease from the center toward the circumference. During the process of condensation the condensing mass will first gain by accretion of meteor- ites; then a balance will be maintained be- tween those which remain on the condensing mass and those which rebound from it; and, finally, more will be lost by rebounding than gained by accretion. The Sacred Maori Axet— The thought of a connection between ancient stone weapons and thunder is widely diffused, and has a hold even in European minds. A curious illustration of its character has been communicated to " Nature " by Mr. Edward Tregear, of Wellington, New Zealand., in the shape of a translation from a Maori news- paper of the story of the finding of the sacred axe, Te Anhiorangi, which had been hidden by a remote ancestor, and had not been seen again till December, 188V. A party of Maoris had gone out to gather the edible mushroom. With them was a young woman, a stranger in the district, and ignorant of the sacred places. Wandering away by herself, and looking here and there for funguses, " she saw a tree on which there was a fungus, and laid her hand on it, but suddenly there came the flash of the axe. Following with her eyes the direction of the flash, she saw the axe close against the foot of a pukatea-tree ; a cry of terror broke from her, and she fled screaming. At the same time the thunder roared, the lightning flashed, and blinding hail burst forth in sudden storm, increasing her terror almost to madness. Her husband heard her cries as she flew along ; but an old man, called Te Rangi Whakairione, directly he heard her shrieks, understood the reason of the outcry, so he began to chant an incan- tation, and the fury of the storm abated. When the party had assembled in the open land, the old priest asked which of them had been to Tieke ; whereupon the girl asked, ' Where is Tieke ? ' The old man answered that it was beyond the turn at Waione. To- mairangi replied : ' I have been there, but I did not know it was a sacred place ; I saw something that looked like a spirit, and I am full of great fear.' Then all the party went to ascertain what it was, and then they found that it was indeed the lost sacred axe, Te Anhiorangi. After Te Rangi Whakairione had chanted another incantation over it, they all took hold of the axe, and wailed over it. When the crying had ceased, they brought the axe back to the settlement." The tra- dition had long existed that the axe was at the spot where it was found, which had there- fore been tabooed, and never visited until on this occasion. On the next day the sacred thing was hung up on a tree, that all might see it, with imposing ceremonies of a proces- sion and priests reciting charms and incanta- tions. " All the people carried green branches in their hands as an offering to Te Anhiorangi. When the concourse drew near the place, successive peals of thunder and flashes of lightning rent the air; then came down a dense fog, making it dark as night. The Tohunga (priests) stopped the thunder and dispersed the darkness by their incantations. When the light again appeared, the people offered the green branches, together with a number of Maori mats, etc. ; then they made lamentations, and sang the old songs in which the ancient axe was spoken of by their forefathers. The pedigree of the axe, which was a stone weapon of extremely high polish, was traced back to the first Maori chief who came to New Zealand ; and to him it had descended, through the great god, Taue, from the primeval pair, Heaven and Earth. Remedies for Sleeplessness. — Correspond- ents of the London " Spectator " have been supplying that journal with various remedies for sleeplessness. A curate in London is afflicted in direct proportion to the mental worry and absence of air and exercise he has to endure, and finds that " to walk even one mile in the day is a great thing" in the way of a remedy. At the moment, he says, the best thing one can do is to get up, drink half a glass of water, and walk round the room. The slight alternation of cold and warmth has a soporific effect. For a per- manent result : " Live healthily. Avoid too little and too much exercise, food, particu- larly wine. Dine lightly, eating very little meat ; drink only one glass of wine. Bathe an hour before dinner, not before going to bed. ... Do something in the evening that does not excite you, something like whist that does itself mechanically. Decide how POPULAR MISCELLANY. 427 much sleep you ought to have — say, eight hours — and get up sternly when you have been in bed eight hours, however long you have been awake. Increase your air and exercise gradually." A journalist, when suffering from an over-excited brain, and finding his eyes in constant movement, although the lids are closed, resolutely fixes the gaze downward — say, to the foot of the bed — while the lids are kept closed. If his sleeplessness arises from flatulence, he takes a remedy for that. " A most wretched lier- awake" of thirty-five years' standing, who had for ten years thought himself happy if he could get twenty minutes' sleep in the twenty-four hours, took hot water — " a pint, comfortably hot, one good hour before each of my three meals, and one the last thing at night — naturally, unmixed with anything else. The very first night I slept, for three hours on end, turned round, and slept again till morning. I have faithfully and regularly continued the hot water, and have never had one ' bad night ' since. Pain gradually less- ened, and went ; the shattered nerves became calm and strong, and instead of each night being one long misery spent in wearying for the morning, they are all too short for the sweet, refreshing sleep I now enjoy." The Mental Torpor Remedy.— Complete intellectual torpor is recommended as a remedy for overweariness by a writer who, to sustain his view, brings pertinent illustra- tion to the support of argument. Such a condition is almost superstitiously avoided by hard-working men, who are disposed to regard it as a waste and an idle indulgence. But " there is no more harm in intellectual torpor for the sake of the mind's health, than in sleep for the sake of the body's health ; and its duration ought to be gov- erned only by expediency. ... As to the curative effect of torpor, we have no doubt whatever. So far from the mind being weakened by total rest, or the energies dimin- ished, both wake after a time fully recov- ered, and repossessed of the old readiness to exert themselves to fatigue. 'I am tired,' says the cured man to himself, ' of doing nothing' — that is, he has recovered the power to do things easily, which is the mark of mental health. The mind itself is, in fact, often positively stronger, having grown in its sleep as the body grows, and having, so to speak, resharpened its weapons, till the 'lazy' mathematician can not only solve bis old problems more quickly, but can recol- lect them more accurately, the mind having gained, as in boyhood it gained, from sleep. We can all recollect how in school-days the lesson of the evening was often best known on the following morning, although, if tor- por weakens, we ought in the intervening twelve hours to have invariably lost some slight grip of the words, instead of gaining a fresh one. The memory in particular re- covers under this process in the most amaz- ing way, so that even the permanent weak- ness, the slowness of recollection which comes of advancing years, seems to disap- pear. The grand gain, however, is in mental nerve, in the disappearance of that appre- hensive anxiety and sense, not of strain which is, but of strain which is coming, that, far more than actual toil, however severe, shatters men's powers to pieces. But how is torpor to be attained ? Like everything else, by determining to have it — that is, by a persistent resolve to be lazy, to do noth- ing, read nothing, think nothing, and say nothing, that involves the smallest up- springing of the sense either of trouble or of effort." Animal Language. — Whether animals can " talk," and men can learn to under- stand their "language," is the subject of an article by Mr. F. G. Frazer in the " Archaeo- logical Review." A critic of the paper de- nies the human part in the matter, and de- clares that the supposition that men can learn to understand animals to the extent implied "is a direct contradiction to universal and unbroken human experience." All rep- resentations asserting such an achievement as a fact, or assuming its possibility, are vain boastings or imaginings. Yet beasts and birds all utter sounds, and sounds that have meaning to them, and meanings which to a certain extent we can understand. " They all utter, or at least they all seem to utter, the same sounds to express the same emo- tions. The love-cry of the nightingale, the low by which a cow recalls a straying calf, the grunt of a pig when it sees food, the mew of a cat who wants the door opened — that is, wants to attract attention — the bark 428 THE POPULAR SCIENCE MONTHLY of a domesticated dog to testify recognition, and the howl of an uncivilized dog as the moon rises, or of a civilized dog when the church-bells begin, are all, to human ears at least, unchanging sounds, sounds with one meaning and no other." So with numerous other familiar sounds peculiar to certain ani- mals, and well understood ; but they can not be regarded as " language " in the sense in which the term is used in the proposition under review. An interesting detail of the discussion concerns the grating sound — not unlike the " gnashing of teeth " — of the scold- ing or " swearing " of birds, which they utter also evidently in play — as kittens and dogs are also fond of playing bite, and dogs bark. However much there may be that one can not learn of the " language of ani- mals," the study of the little that is at our command is enough to furnish profitable as well as amusing occupation. A Glance at Cambodia. — A French trav- eler, writing from Penompein, the capital of Cambodia, says that "in passing from Co- chin China to Cambodia, the difference be- tween the Cambodian and the Annamite type is very striking. The Cambodian is al- most the height of Europeans, and is idle and dirty, while the Annamite is small and active. A full-grown Annamite woman is like a French girl of twelve. A book on Cambodia would be very interesting. The banks of the river are covered with luxu- riant vegetation. The entire territory and its inhabitants belong absolutely to the king, who lives here, with a second and third king besides him, while a fourth king is stationed in the interior. He has three hundred wives, chosen from the handsomest women in the whole country. The second king at present is in opposition to King Merodom. All the Cambodians are the king's earraen or slaves, and pay him rent. . . . The country is a most curious one. Elephants are very numerous here, and wander about in freedom through the brushwood, like oxen in the meadows of France. The capital of Cambodia consists of only one street, which is nearly four miles long. In all the town there are not ten houses built of stone or of bricks, and those so built are public buildings. All the offi- cers are lodged together in two payothes, which are almost contiguous. A payollu is composed of a wooden floor resting in turn on a scaffolding of bamboo. The walls are formed of a trellis of straw or leaves, in the style of the thatch of cottages all over Eu- rope. If you push with your finger a little strongly, it will pass through the wall. The roof is of thatch. The furniture is very primitive. It consists of a bed, formed of a frame in bamboo on which is placed a mat, and a table." Stages of Himalayan Vegetation. — Gen- eral R. Strachey describes the changes which the traveler meets in ascending one of the great mountain-ranges, as embodying a com- pendium of the climates and vegetation of the entire globe. Nowhere can such a display be better or more easily obtained than upon the Himalayas. The transition is abrupt from the well - cultivated plain of northern India, with its fields of rice and millet, or golden-flowering mustard, to the dense, um- brageous forests along their base, almost wholly composed of trees of tropical forms, with a few oaks and an elm, which, with a tangled growth of undershrubs and creep- ers and epiphytal plants, give cover to the elephant, the rhinoceros, and tiger, and af- ford shelter to the peacock and other gayly colored birds. The glens are choked with gigantic grasses and feathering bamboos. Great forests cover the outer ranges of the chain, scandent palms spreading over the lofty trees, whose stems are splendidly fur- nished with the dark-green foliage of climb- ing aroids ; the ground beneath them is con- cealed under a rich growth of tree and other ferns, orchids, and Scitaminece, or broad- leaved plantains. With gradually increas- ing elevation and falling temperature the character of the vegetation changes. More open woods of evergreen trees, typical of warm temperate climates, succeed, including rhododendrons, oaks, and laurels. Lofty pines cover the vast mountain-slopes through many thousand feet of altitude in unbroken uniformity. Still ascending, are reached forests of deciduous trees of surpassing size and beauty, crowning the hill-tops and fring- ing the courses of the rivers, intermingled with many flowering shrubs and an abun- dant display of herbaceous plants, of which, at the greater elevations, the forms are for the most part allied to or identical with POPULAR MISCELLANY. 429 those of Europe. The arboreous vegetation, the last members of which are commonly birches, pines, and junipers, usually ends at about twelve or thirteen thousand feet above the sea-level, the shrubby growths ascend- ing a thousand feet higher. The Alpine region is thus attained, where, under the influence of the frequent showers that fall upon the mountain -slopes exposed to the south, the open pastures are adorned, during their short summer, with flowers of every hue and in the greatest profusion and lux- uriance, including well - known European forms, such as gentian, primula, anemone, ranunculus, and many others. With in- creased elevation, and as the ranges are less directly exposed to the rain-bearing winds from the south, the climate becomes colder and drier, the vegetation more scanty, the forms fewer ; and on reaching the border of Thibet, at an elevation of fourteen or fifteen thousand feet, where the atmospheric condi- tions are wholly changed, the aspect of the country is that of a desert — treeless and bare, as a rule — and, excepting in the rare neighborhood of water, not one twentieth of the surface is clothed with vegetation, and such bushes as there are seldom rise to a greater height than one or two feet. Experimental Fields at Rotnamstcad. — The grass-land experimental field at Rotham- stead consists of about seven acres, and is divided into twenty plots. It has probably been laid down in grass for some centuries. It is certain that no fresh seed has been artificially sown within the last fifty years ; and there is no record of any having been sown since the grass was first laid down. The experiments were begun in 1856, when the herbage was uniform in character. Each plot has been treated differently. One has had no manure, others have had farm-yard dung, superphosphate of lime, ammonia salts, sulphate of potash, or other chemicals. Sir John Lawes said to a writer in the " Pall Mall Gazette," who visited the farm, that "the result was evident in many ways. On one plot the fertilizers supplied had fed only a single kind of grass, which had covered the whole area, killing out all the rest. On an- other the grass was hard and wiry, scarcely fit for food ; and on yet another the land was little better than a bog. We can not go into technical details as to the results, but these experiments have shown that the food which plants receive, either artificially from the soil, or by the atmosphere, determines their nature as much as in the case of animals. The same thing is seen in the wheat and barley fields. One of the most important of the former is a section upon which the grain has been grown continuously for forty-five years, in one case without manure. The average of the first recorded eighteen years gave 14| bushels per acre, and last year the same quantity was produced, showing that in the soil there is a large reserve amount of fertility." In another part of the field, Sir John Lawes told the writer : " Five years ago we left the upper end of this wheat-field un- cropped, allowing the corn to fall when ripe. In three years there was scarcely a single ear of corn left ; those which I could find were short in the stalk, and with perhaps a single grain. Now there is not one. This shows that food-products are almost entirely arti- ficial, and that in a few years the land would be a perfect wilderness, if uncultivated. But I myself was surprised at the rapidity with which the wheat disappeared." This was ex- plained thus : " The weeds were stronger, and killed out the artificial grain. Weeds are hardy, and it is really 'the survival of the fittest ' or the hardiest. The same thing I can show you in the turnip-field, where the un- manured plot is almost barren, the plants having scarcely in any case formed a bulb. It is the starch we want as food. Cultivation and fertilization give that starch." Palm-Oil. — Palm-oil is the product of the fruit of the oil-palm tree of Guinea. The fruit grows in clusters on top of the tree, which is about thirty feet high, and resem- bles a chestnut. The oil is extracted by boiliDg the pulpy and fibrous mass around the central nut, and is used in making soap and candles. The fruits are harvested :n April. The oil of Arachis, which is equally important in commerce, is from the nut of the Arachis (peanut), thousands of tons of which are sent to Europe every year to be made up into "olive-oil." It is the fruit of an annual creeping plant (Arachis hypogea), and ripens in July and August. Oils of in- ferior quality are made into soap. Another underground nut ( Voandzeia subterranea) 43° THE POPULAR SCIENCE MONTHLY. affords a white, hard butter, richer than but- ter from the cow, which has the further ad- vantage of remaining fresh for a whole year without being salted. Only limited quanti- ties of this product have as yet come into the market. The native Africans use all these fruits, under one form or another, for their own alimentation. Flowers and Perfumes. — The rose is ex- tensively cultivated in the Balkan Peninsula, chiefly for the sake of the perfume it af- fords. The Provence or cabbage rose, it is said, will yield in the second year from one hundred to two hundred bushels of flowers per acre, weighing six pounds to the bushel. The rose harvest at Adrianople sometimes yields about ninety-four thousand ounces of attar of roses ; the average of the Bulgarian harvests in the past ten seasons has been fifty-seven thousand ounces. The price of this perfume has declined fifty per cent since 18S3. The Moors in Algeria extract an at- tar of moderate value from the indigenous double white musk rose. Twenty-eight tons of rose-leaves were imported into Aden in 1886, of which half were shipped to India. The " ixora extract " is made from the soka- flower {Parvclta angustijlora) ; frangipanni, from the flowers of species of Plumcria, na- tive to the West Indies and some parts of South America ; the essence and pomade of cassie, of the French perfumers, from the flowers of Acacia famesicina. About one hundred tons of these flowers are used in Cannes yearly, individual makers working up one hundred thousand pounds. The fra- grant white flowers of Bligltia sapida and of the Bukul {Mimusops Elengi) are used for making distilled waters ; and the flowers of spikenard {Andropoc/on nardus) are employed in Algeria for perfuming hair-oils and cos- metics. Moorish women form garlands to ornament. the interior of their dwellings from the flowers of the jasmine, and obtain a perfume by steeping them with oil in bottles, which are exposed to the sun. The same process is applied to the flowers of the tu- berose and the cassia. Hungary water is distilled with spirit from the tops of rose- mary-flowers. Twenty tons of violets are used annually in Nice and Cannes, and one hundred and twenty tons of orange-blossoms in Nice. Orange-flower water is one of the most agreeable vehicles for nauseous medi- cines that we have. Rose-buds are made into preserves in Arabia; the blossoms of the shaddock are used for flavoring sweet- meats, and the fleshy calyces or flower-bracts of the Indian sorrel, a Hibiscus, having a pleasant acid taste, are made into tarts, jellies, and refreshing drinks in India. The petals of flowers arc much used in Roumania for flavoring preserves, of which not less than one hundred and fifty varieties are made. NOTES. Attention has been called, in letters writ- ten by Mr. James R. Skilton to the Mayor of Brooklyn, to the dangers that are hidden in the pipes through which water-gas is con- veyed into houses and in the meters. The pipes and the meters are often — it would hardly be too much to say, usually — leaky, and as the escaping gas, largely carbonic oxide, while extremely poisonous, is imper- ceptible to the senses, great harm may be and often is wrought before the family are aware that anything is wrong. It is hard, even when the nuisance is known to exist, to force timely attention from the compa- nies furnishing the gas, and, when they do send men to make repairs, the work is, as a rule, done in the most negligent manner. Mr. Skilton has no doubt that " hundreds of people are sacrificed every year to the Mo- loch of the gas-meter." In the " Monthly " for July there is a note in which Asamayama is spoken of as the highest active volcano in Japan. This is popularly correct, but is not scientifically exact. Asamayama is 8,284 feet high (Rein). The last fatal eruption took place in 1783, and the last emission of ashes occurred in 1870, while the evidences of volcanic erup- tion are much more conspicuous than they are around Fujiyama, the height of which is 12,287 feet (ibid.), and which has been quiet — i. e., not violently active — since 1707. But when one sees the " hot " place on the side of Fuji, it becomes very apparent that the activity of Asama is very little greater than that of her peerless sister. The heat at one place on Fuji is so great as to be per- ceptible to the hand. Snow will not lie ; and it is said that there is an escape of steam. Borings of rock-salt at Ellsworth and Kingman, Kansas, were described by Mr. Robert Hay at the meeting of the American Association. The veins were discovered in April and August, 1888. One hundred and fifty-five barrels of salt were manufactured in Kansas in 1888, and it is estimated that the output of 1889 will not be less than three times as large. NOTES. 43i Respecting "artists' colors," Dr. A. P. Laurie said, in the British Association, that one point that came out in the course of his inquiries about the colors used by the old mas- ters was the fact that they largely employed vegetable pigments, many of which were not used by modern painters. His researches into the ordinary methods of manufacturing colors showed that great variations prevailed in different makes of the same color, and the matter was an important one to look after. One of the most valuable oils used by the old masters was that of the walnut. The work of Columbus is to be commem- orated in Italy according to a scheme adopt- ed by a Royal Commission, which includes the publication of a "Raccolta Colombiana" in six volumes, devoted to (1) the writings of Columbus ; (2) Columbus and his family ; (3) the discovery of America; (4) navigation and cartography of the discovery ; (5) mono- graphs (Italian precursors and continuers of the work of Columbus) ; (0) bibliography. This work will apparently be the outcome of a large amount of diligent research. The establishment of a biological labora- tory for the observation and study of fresh- water Algce was suggested by Mr. William R. Dudley, in a paper read at the meeting of the American Association. Prof. J. W. Mallet has found, in experi- ments upon alum baking-powders, that most of the preparations of that class in the mar- ket are made with alum, the acid phosphate of calcium, bicarbonate of sodium, and starch. Among the resultants of the chemical changes by baking are aluminum hydroxide and phos- phate. These substances, in doses not very greatly exceeding such quantities as may be derived from bread as commonly used, pro- duce an inhibitory effect upon gastric diges- tion. This effect is probably due to precipi- tation in insoluble form of the organic sub- stance constituting the peptic ferment and of some of the organic matter of food. Hence it is concluded that "not only alum itself, but the residues which its use in baking- powder leaves in bread, can not be viewed as harmless, but must be ranked as objection- able." According to a calculation furnished us by Prof. William Harkness, of the Naval Observatory, "a body weighing one pound avoirdupois on a spring balance at the earth's equator would weigh only (V16584 of a pound, or 2*6534 ounces, upon the same spring bal- ance, at the moon's equator. In the state- ments on this subject appearing in books the centrifugal force is neglected. It amounts to 24 grains in an avoirdupois pound of 7,000 grains. According to a paper by Prof. Wiley, in the Society for promoting Agriculture, the butter of cows fed on cotton-seed is marked by the presence of a small supply of volatile acid and a high melting-point. The power possessed by cotton-seed oil of acting on silver, passes through the animal, and appears in the butter made from ita milk — a fact which shows that substances can be carried directly from the food to the butter. A new standard of analysis will have to be adapted to the butters of cows fed on cotton-seed oil, for the low amount of volatile acid contained in them would cause them to be condemned as spurious. The relative values as foods of the grains named below are given by Prof. Wiley as, first, wheat ; second, sorghum ; third, maize ; fourth, unhulled oats. Sorghum-seed fur- nishes a flour like buckwheat, that makes passable bread, and is coming into consid- erable use. The workmen in the Venetian glass fac- tories at Murano, according to Dr. Salviati, fall victims in time to failure of eye-sight and ultimate blindness, caused by the excess- ive heat and intense glare of the furnaces. As they live simply and receive high wages, they are usually able to save enough before the disability comes upon them to support them for the remainder of their lives. Prop. Renzi, of Naples, has reported cures of tetanus by securing absolute rest for the patient — that is, rest for the senses as well as for the body. The patient's ears are closed with wax, his room is dark, and the floor is heavily carpeted. His nurse at- tends him with a shaded lantern ; he is served food that requires no mastication ; and sedatives are given to relieve pain. It is not pretended that this treatment short- ens the period of the disease, but that it lessens the force of the paroxysms, which eventually cease. Experiments by Dr. Pinel show that hypnotic patients will obey the directions conveyed to them mechanically by the pho- nograph as readily as they will obey living words. Hence, he argues, the theory of ani- mal magnetism — that is, of a magnetic cur- rent passing from operator to subject — is baseless ; and the real cause of the phe- nomena of hypnotism is a disordered men- tal state. A. W. Buckland has endeavored to re- store to the moon the credit that has been snatched from it of having influence over the weather and the welfare of men. Some of the superstitions relative to the moon may be traced to the old moon-worship. For others, Mr. Buckland assumes, ground may be found in fact. Meteorologists deny any influence of the moon upon weather; but the moon raises the tides of the ocean, and it also creates tides in the air, which have received no attention from science. We are ignorant of the forces that may reside in the air-tides and of the phenomena that may be dependent upon them. 432 THE POPULAR SCIENCE MONTHLY. Mr. Bosworth Smith, in a report on the Kolar gold-field, in southern India, records some finds of old mining implements, old timbering, fragments of bones, an old oil- lamp, and broken pieces of earthenware, in- cluding a crucible, the remains of ancient mining operations. He expresses astonish- ment at the fact that the old miners were able to reach depths of two hundred or three hundred feet through hard rock, with the simple appliances at their command. Bcffaloes are said to be becoming very abundant and increasing rapidly in north- ern Australia, where they were introduced about 1S29. They are described as being massive and heavy, " with splendid horns," and affording fine sport for bold hunters. In the discussion in the British Associa- tion of the report of the Committee on Science Teaching in the Elementary Schools (which exhibited a continued decline), Sir Benjamin Browne said that the school boards would be amazed at the high standard of the qualifications of the lads who came to his firm to be apprenticed engineers. Recently a boy thirteen years of age came to him, and he failed to puzzle him with problems from Euclid. His opinion was, that what- ever could be done voluntarily was better than what could be done by the Government. Dr. D. G. Brinton, of Philadelphia, an- nounces as in press a collection of sacred songs of the ancient Mexicans, entitled " Rig Veda Americana," with a gloss in Nahuatl, para- phrase, notes, and vocabulary. The texts are derived from two Nahuatl manuscripts, one at Madrid and the other at Florence, both of which have been personally collated by the editor. This volume will form num- ber eight of the " Library of Aboriginal American Literature." An instrument called the telegraphone has been patented, which enables the sender to record his message on a cylinder attached to the receiving instrument, in the absence of any one to hear it, and even to repeat the message back to himself for correction. Mr. De Cort Smith, at the American Association, exhibited specimens of the Shamanic masks and rattles of the Ononda- ga Indians, and exemplified their use. The masks are symbolical of supernatural evil beings, and their aid is invoked to drive away witches. The spirits are believed to cause or remove illness. They are pro- pitiated with feasts and sacrifices of to- bacco. OBITUARY NOTES. Prof. Victor Eggertz, late head of the School of Mines of Sweden, died in Stock- holm in the last days of August. He was the inventor of what is called the coloration test for analyzing carbon in iron and steel. Mr. E. F. H. Francis, Professor of Chemistry in Queen's College, Georgetown, Demerara, and analytical chemist to the Government, has recently died, aged thirty- nine years. He went to the service in Brit- ish Guiana from a similar position in Trini- dad in 1875. Senor Don Sebastian Vidal, who died at Manila July 28, 1889, had been for several years Inspector-General of Forests and Di- rector of the Botanic Garden at Manila, and was the author of several works on Philip- pine botany. He was practically a pioneer in the investigation of the Philippine flora, and has determined several peculiarities distinguishing it from the allied Malayan flora. Mr. John Ball, F. R. S., a distinguished traveler, Alpine explorer, and botanist, of England, died in London, October 10, 1889, soon after returning from an excursion to the Dolomite Alps. He was born in Dublin in 1818; won high mathematical honors at Cambridge ; was called to the bar, and ap- pointed an assistant Poor Law Commissioner, served in Parliament and as Under Secretary for the Colonies, and then withdrew from public life and devoted himself to Alpine exploration and botany. He accompanied Sir Joseph Hooker to Morocco, and wrote an account of the botany and natural history of the highlands of that country. He also vis- ited Peru and Patagonia and the Island of Tcneriffe, for scientific exploration. He published an "Alpine Guide," which is spoken of as a work of standard merit. The distinguished French chemist, Dr. Augustin Quesneville, died on the 4th of November, 1889, aged eighty years. He was a pupil of Vauquclin's, and succeeded him in his factory. Having attended Chev- reul's lectures, he was admitted as a doctor of medicine in 1S34, from which time he devoted himself to the study of science and industrial chemistry. In 1840 he founded a monthly journal, called at first the "Revue Scientifique," but after 1S57 the "Mcniteur Scientifique," devoted to chemistry and its industrial applications. This journal was continued till October last, when the veteran editor gave it up, on account of the pressure of old age. "Ciel et Terre" records the death, on the 10th of October, in bis sixty-sixth year, of M. Francois Henri Carlier, proprietor and director of the Meteorological Observa- tory of Saint Martin-de-IIinx in the Landes. This establishment is described as having been a model one, and better furnished than many state-supported observatories. The observations taken there under M. Carlier during the past twenty-five years form one of the most important contributions to the study of the climate of the extreme south- east of France. JAMES GLAISHER. / THE POPULAR SCIENCE MONTHLY. FEBRUARY, 1890. NEW CHAPTERS IN THE WARFARE OF SCIENCE. VII. COMPARATIVE MYTHOLOGY. By ANDREW DICKSON WHITE, LL.D., L.H.D., EX-PRESIDENT OF CORNELL UNIVERSITY. PART I. A FEW years since, Maxime Du Camp, an eminent member of the French Academy, traveling from the Red Sea to the Nile through the Desert of Kosseir, came to a barren slope covered with bowlders, rounded and glossy. His Mohammedan camel-drivers accounted for them on this wise : " Many years ago Hadji Abdul- Aziz, a sheik of the dervishes, was traveling on foot through this desert ; it was summer ; the sun was hot and the dust stilling ; thirst parched his lips, fatigue weighed down his back, sweat dropped from his forehead, when looking up he saw — on this very spot — a garden beautifully green, full of fruit, and, in the midst of it, the gardener. " ' O fellow-man/ cried Hadji Abdul- Aziz, s in the name of Allah, clement and merciful, give me a melon and I will give you my prayers.' " The gardener answered, ' I care not for your prayers ; give me money, and I will give you fruit.' " ' But/ said the dervish, * I am a beggar ; I have never had money ; I am thirsty and weary, and one of your melons is all that I need.' "'No,' said the gardener, 'go to the Nile and quench your thirst.' " Thereupon the dervish, lifting his eyes toward heaven, made this prayer : ' O Allah, thou who in the midst of the desert didst make the fountain of Zem-Zem spring forth to satisfy the thirst vol. xxxvi. — 28 434 THE POPULAR SCIENCE MONTHLY. of Ismail, father of the faithful ; wilt thou suffer one of thy creat- ures to perish thus of thirst and fatigue ? ' " And it came to pass that, hardly had the dervish spoken, when an abundant dew descended upon him, quenching his thirst and refreshing him even to the marrow of his bones. " Now at the sight of this miracle the gardener knew that the dervish was a holy man, beloved of Allah, and straightway of- fered him a melon. " ' Not so/ answered Hadji Abdul- Aziz, ' keep what thou hast, thou wicked man. May thy melons become as hard as thy heart, and thy field as barren as thy soul ! ' "And straightway it came to pass that the melons were changed into these blocks of stone, and the grass into this sand, and never since has anything grown thereon/' In this story, and in myriads like it, we have a survival of that early conception of the universe in which so many of the leading moral and religious truths of the great sacred books of the world are imbedded. All ancient sacred lore abounds in such mythical explanations of remarkable appearances in nature, and these are most fre- quently prompted by mountains, rocks, and bowlders seemingly misplaced. In India we have such typical examples among the Brahmans as the mountain-peak which Durgu threw at Parvati ; and among the Buddhists the stone which Devadatti hurled at Buddha. In Greece the Athenian, rejoicing in his belief that Athena guarded her chosen people, found it hard to understand why the great rock Lycabettus should be just too far from the Acropolis to be of use as an outwork ; but a myth was developed which ex- plained all. According to this, Athena had intended to make Lycabettus a defense for the Athenians, and she was bringing it through the air from Pallene for that very purpose ; but, unfor- tunately, a raven met her and informed her of the wonderful birth of Erichthonius, which so surprised the goddess that she dropped the rock where it now stands. So, too, a peculiar rock at JEgina was accounted for by a long and circumstantial legend to the effect that Peleus threw it at Phocas. A similar mode of explaining such objects is seen in the my- thologies of northern Europe. In Scandinavia we constantly find rocks which tradition accounts for by declaring that they were hurled by the old gods at each other, or at the early Christian churches. In Teutonic lands, as a rule, wherever a strange rock or stone is found, there will be found a myth or a legend, heathen or Christian, to account for it. NEW CHAPTERS IN THE WARFARE OF SCIENCE. 435 So, too, in Celtic countries ; typical of this mode of thought in Brittany and in Ireland is the popular belief that such features in the landscape were dropped by the devil or by fairies. Even at a much later period such myths have grown and bloomed ; Marco Polo gives a long and circumstantial legend of a mountain in Asia Minor which, not long before his visit, was re- moved by a Christian who had " faith as a grain of mustard- seed," and, remembering the Saviour's promise, transferred the mountain to its present place by prayer, " at which marvel many Saracens became Christians." * Similar mythical explanations are also found, in all the older religions of the world, for curiously marked meteoric stones, fos- sils, and the like. Typical examples are found in the imprint of Buddha's feet on stones in Siam and Ceylon ; in the imprint of the body of Moses, which down to the middle of the last century was shown near Mount Sinai ; in the imprint of Poseidon's trident on the Acropo- lis at Athens ; in the imprint of the hands or feet of Christ on stones in France, Italy, and Palestine ; in the imprint of the Vir- gin's tears on stones at Jerusalem ; in the imprint of the feet of Abraham at Jerusalem and of Mohammed on a stone in the Mosque of Khait Bey at Cairo ; in the imprint of the fingers of giants on stones in the Scandinavian Peninsula, in north Germany, and in western France ; in the imprint of the devil's thighs on a rock in Brittany, and of his claws on stones which he threw at churches in Cologne and Saint Pol-de-Le'on ; in the imprint of the shoulder of the devil's grandmother on the " elbow-stone " at the Mohriner- see; in the imprint of St. Otho's feet on a stone formerly pre- served in the castle church at Stettin ; in the imprint of the little finger of Christ and the head of Satan at Ehrenberg ; and in the imprint of the feet of St. Agatha at Catania, in Sicily. To ac- count for these appearances and myriads of others, long and in- teresting legends were developed, and out of this mass we may take one or two as typical. * For Maxime Du Camp, see "Le Nil, Egypte et Nubie," Paris, 1877, chapter v.

Such a science makes the sacred books of the world more and more precious, in that it shows how they have been the necessary envelopes of our highest spiritual sustenance; how even myths and legends apparently the most puerile have been the natural husks and rinds and shells of our best ideas ; and how the atmos- phere is created in which these husks and rinds and shells in due time wither, shrivel, and fall away, so that the fruit itself may be gathered to sustain a nobler religion and a purer morality. The coming in of Christianity contributed elements of inestima- ble value in this evolution, and, at the center of all, the thoughts, words, and life of the Master. But when, in the darkness that followed the downfall of the Roman Empire, there was developed a theology and a vast ecclesiastical power to enforce it, the most interesting chapters in this evolution of religion and morality were unfortunately removed from the domain of science. So it came that for over eighteen hundred years it has been thought natural and right to study and compare the myths and legends arising east and west and south and north of Palestine with each other, but never with those of Palestine itself ; so it came that one of the regions most fruitful in materials for rever- ent thought and healthful comparison was held exempt from the unbiased search for truth ; so it came that, in the name of truth, truth was crippled for ages. While observation, and thought upon observation, and the organized knowledge or science which results from these, progressed as regarded the myths and legends of other countries, and an atmosphere was thus produced giving purer con- ceptions of the world and its government ; myths of that little geographical region at the eastern end of the Mediterranean re- tained possession of the civilized world in their original crude form, and have at times done much to thwart the noblest efforts of religion, morality, and civilization. The history of myths — of their growth under the earlier phases of human thought and of their decline under modern thinking — is one of the most interesting and suggestive of human studies ; but, since to treat it as a whole would require volumes, I shall select only one small group, and out of this mainly a single myth — one about which there can no longer be any dispute — the group of myths and legends which grew upon the shore of the Dead Sea, and especially that one which grew up to account for the successive salt columns at its southwestern extremity. The Dead Sea is about thirty-nine geographical miles in NEW CHAPTERS IN THE WARFARE OF SCIENCE. 443 length and nine miles in width; it lies in a very deep fissure extending north and south, and its surface is about thirteen hun- dred feet below that of the Mediterranean. It has, therefore, no outlet, and is the receptacle for the waters of the whole system to which it belongs, including those collected by the Sea of Galilee and brought down thence by the river Jordan. It certainly — or, at least, the larger part of it — ranks geologi- cally among the oldest lakes on earth. In a broad sense the re- gion is volcanic: on its shore are evidences of volcanic action which must, from the earliest period, have aroused wonder and fear, and stimulated the myth-making tendency to account for them. On the eastern side are impressive mountain-masses which have been thrown up from old volcanic vents ; mineral and hot springs abound, some of them spreading sulphurous odors ; earth- quakes have been frequent, and from time to time these cast up masses of bitumen ; concretions of sulphur and large formations of salt constantly appear. The water which comes from the springs or oozes through the salt layers upon its shores constantly brings in various salts in solution, and, being rapidly evaporated under the hot sun and dry wind, there has been left, in the bed of the lake, a strong brine heavily charged with the usual chlorides and bromides — a sort of bitter " mother liquor." This fluid has become so dense as to have a remarkable power of supporting the human body ; is of an acrid and nauseating bitterness ; and by ordinary eyes no evi- dence of life is seen in it. Thus it was that in the lake itself, and in its surrounding shores, there was enough to make the generation of explanatory myths on a large scale inevitable. The main northern part of the lake is very deep, the plummet having shown an abyss of thirteen hundred feet, but the south- ern end is shallow and in places marshy. The system of which it forms a part shows a likeness to that in South America, of which the mountain lake Titicaca is the main feature ; as a receptacle for surplus waters, only rendering them by evaporation, it resembles the Caspian and many other seas ; as a sort of evaporating dish for the leachings of salt rock, and consequently holding a body of water unfit to support the higher forms of animal life, it resembles, among others, the Me- dian lake of Urumiah ; as a deposit of bitumen, it resembles the pitch lakes of Trinidad. Striking, then, as was the Dead Sea in its appearance to pre- scientific man, there is nothing in it of extraordinary difficulty to the modern geologist or geographer.* * For modern views of the Dead Sea, see the Rev. Edward Robinson, D. D., " Biblical Researches," various editions ; Lynch's " Exploring Expedition " ; De Saulcy, " Voyage 444 THE POPULAR SCIENCE MONTHLY. At a very early period, myths and legends, many and long, grew up to explain features then so incomprehensible. As the myth and legend grew up among the Greeks of a refusal of hospitality to Zeus and Hermes by the village in Phrygia, and the consequent sinking of that beautiful region with its inhabitants beneath a lake and morass, so there came a belief in a similiar offense by the people of the beautiful valley of Siddim, and the consequent sinking of that valley with its in- habitants beneath the waters of the Dead Sea. Very similar to the accounts of the saving of Philemon and Baucis are those of the saving of Lot and his family.

NEW CHAPTERS IN THE WARFARE OF SCIENCE. 445 diseval and modern period until they have quietly withered away in the light of modern scientific investigation, leaving to us the religious and moral truths they inclose. It would be interesting to trace this whole group of myths : their origin in times prehistoric; their development in Greece and Rome ; their culmination during the ages of faith ; and their disappearance in the age of science. It would be especially in- structive to note the conscientious efforts to prolong their life by making futile compromises between science and theology regard- ing them ; but I shall mention this main group only incidentally, confining myself almost entirely to the one above named — the most remarkable of all — the myth which grew about the salt pil- lars of Usdum. I select this mainly because it involves only elementary prin- ciples, requires no abstruse reasoning, and because all controversy regarding it is ended. There is certainly now no theologian with a reputation to lose who will venture to revive the idea regarding it which was sanctioned for hundreds, nay thousands, of years by theology, was based on Scripture, and was held by the universal Church until our own century. The main feature of the salt region of Usdum is a low range of hills near the southwest corner of the Dead Sea, extending in a southeasterly direction for about five miles, and made up mainly of salt rock. This rock is soft and friable, and, under the influ- ence of the heavy winter rains, it has been, without doubt, from a period long before human history, as it is now, cut ever into new shapes, and especially into pillars or columns, which sometimes bear a resemblance to the human form. A clergyman who visited this spot about ten years since speaks of the appearance of this salt range as follows : " Fretted by fitful showers and storms, its ridge is exceedingly uneven, its sides carved out and constantly changing ; . . . and each traveler might have a new pillar of salt to wonder over at intervals of a few years." * Few things could be more certain than that, in the indolent * As to the substance of the " pillars " or "statues" or "needles " of salt at Usdum, many travelers speak of it as "marl and salt." Irby and Mangles, in their " Travels in Egypt, Nubia, Syria, and the Holy Land," chapter vii, call it " salt and hardened sand." The citation as to frequent carving out of new " pillars " is from the " Travels in Palestine" of the Rev. H. F. Osborn, D. D. See also Palmer, " Desert of the Exodus," ii, pp. 478, 479. For engravings of the salt pillar at different times compare that given by Lynch in 1 848, when it appeared as a column forty feet high, with that given by Palmer as the frontis- piece to his " Desert of the Exodus," Cambridge, England, 1871, when it was small and " does really bear a curious resemblance to an Arab woman with a child upon her shoulders " ; and this again with the picture of the salt formation at Usdum given by Canon Tristram, at whose visit there was neither " pillar " nor " statue." See " The Land of Israel," by H. B. Tristram, D. D., F. R. S., London, 1882, p. 324. 446 THE POPULAR SCIENCE MONTHLY. dream-life of the East, myths and legends would grow up to ac- count for this as for other strange appearances in all that region. The question which a religious Oriental put to himself in ancient times at Usdum was substantially that which his descendant to- day puts to himself at Kosseir : " Why is this region thus blasted?" — " whence these pillars of salt ? " or " whence these blocks of granite ? " — " what aroused the vengeance of Jehovah or of Allah to work these miracles of desolation ? " And, just as Maxime Du Camp recorded the answer of the modern Shemite at Kosseir, so the compilers of the Jewish sacred books recorded the answer of the ancient Shemite at the Dead Sea ; just as Allah at Kosseir blasted the land and transformed the melons into bowlders which are seen to this day, so Jehovah at Usdum blasted the land and transformed Lot's wife into a pillar of salt which is seen to this day. No more difficulty was encountered in the formation of the Lot legend, to account for that rock resembling the human form, than in the formation of the Niobe legend, which accounted for a supposed human resemblance in the rock at Sipylos ; it grew up just as we have seen thousands of similar myths and legends grow up about striking natural appearances in every home of the human race. Being thus consonant with the universal view re- garding the relation of physical geography to the divine govern- ment, it became a treasure of the Jewish nation and of the Chris- tian Church — a treasure not only to be guarded against all hostile intrusion, but to be increased, as we shall see, by the myth-mak- ing powers of Jews, Christians, and Mohammedans for thousands of years. The spot where the myth originated was carefully kept in mind; indeed, it could not escape, for in that place alone was constantly seen the phenomena which caused the myth. We have a steady chain of testimony through the ages all pointing to the salt pillar as the irrefragable evidence of divine judgment. That great theological test of truth — the dictum of St. Vincent of Lerins — would certainly prove that the pillar was Lot's wife ; for it was believed so to be by Jews, Christians, and Mohammedans from the earliest period down to a time almost within present memory — " always, everywhere, and by all." It would stand per- fectly the ancient test insisted upon by Cardinal Newman, " Se- curus judicat orbis terrarum." For, ever since the earliest days of Christianity, the identity of the salt pillar with Lot's wife has been universally held and supported by passages in Genesis, in St. Luke's Gospel, and in the Second Epistle of St. Peter — coupled with a passage in the book of the Wisdom of Solomon, which to this day, by a majority in the Christian Church, is believed to be inspired, and from which are NEW CHAPTERS IN THE WARFARE OF SCIENCE. 447 specially cited the words, " A standing pillar of salt is a monu- ment of an unbelieving soul." * Never was chain of belief more continuous. In the first cent- ury of the Christian era Josephus refers to the miracle, and de- clares regarding the statue, " I have seen it, and it remains at this day " ; and Clement, Bishop of Rome, one of the most revered fathers of the Church, noted for the moderation of his statements, expresses a similar certainty, declaring that he knew the miracu- lous statue to be still standing. In the second century that great father of the Church, bishop and martyr, Irenseus, not only vouched for it, but gave his ap- proval to the belief that the soul of Lot's wife still lingered in the statue, giving it a sort of organic life ; thus virtually began in the Church that amazing development of the legend which we shall see taking various forms through the middle ages — the story that the salt statue exercised certain physical functions which in these more delicate days can not be alluded to save under cover of a learned language. This addition to the legend, which in these signs of life, as in other things, is developed almost exactly on the same lines with the legend of the Niobe statue in the rock of Mount Sipylos and the legends of human beings transformed into bowlders in various mythologies, was for centuries regarded as an additional confir- mation of revealed truth. In the third century the myth burst into still richer bloom in a poem long ascribed to Tertullian. In this poem more miracu- lous characteristics of the statue are revealed. It could not be washed away by rains; it could not be overthrown by winds; any wound made upon it was miraculously healed; and the earlier statements as to its physical functions were amplified in sonorous Latin verse. With this appeared a new legend regarding the Dead Sea : it became universally believed, and we find it repeated throughout the whole mediseval period, that the bitumen could only be dis- solved by such fluids as in the processes of animated nature came from the statue. The legend thus amplified we shall find dwelt upon by pious travelers and monkish chroniclers for hundreds of years : so it came to be more and more treasured by the universal Church, and held more and more firmly — " always, everywhere, and by all." In the two following centuries we have an overwhelming mass of additional authority for the belief that the very statue of salt * For the usual biblical citations, see Genesis xix, 26 ; St. Luke xvii, 32 ; Second Peter ii, 6.

In the fourth the continuance of the statue was vouched for by St. Sil- via, who visited the place : though she could not see it, she was told by the Bishop of Segor that it had been there some time before, and she concluded that it had been temporarily covered by the sea. In both the fourth and fifth centuries such great doctors in the Church as St. Jerome, St. John Chrysostom, and St. Cyril of Jerusalem agreed in this belief and statement ; hence it was, doubtless, that the Hebrew word which is trans- lated in the authorized English version " pillar," was translated in the Vulgate, which the vast majority of Christians believe divinely inspired, by the word " statue " ; we shall find this fact insisted upon by theologians arguing in behalf of the statue, as a result and monument of the miracle, for over fourteen hundred years afterward.* About the middle of the sixth century Antoninus Martyr visited the Dead Sea region and described it, but curiously re- versed a simple truth in these words : " Nor do sticks or straws float there, nor can a man swim, but whatever is cast into it sinks to the bottom." As to the statue of Lot's wife, he threw doubt upon its miraculous renewal, but testified that it was still standing. In the seventh century the Targum of Jerusalem not only testified that the salt pillar at Usdum was once Lot's wife, but declared that she must retain that form until the general resur- rection. In the seventh century, too, Bishop Arculf traveled to the Dead Sea, and his work was added to the treasures of the Church. He develops the legend, and especially that part of it given by Josephus, greatly. The bitumen that floats upon the sea " resembles gold and the form of a bull or camel " ; " birds can not live near it " ; and " the very beautiful apples " which grow there, when plucked, " burn and are reduced to ashes, and smoke as if they were still burning." In the eighth century the Venerable Bede takes these state- ments of Arculf and his predecessors, binds them together in his work on " The Holy Places," and gives the whole mass of myths and legends an enormous impulse, f In the tenth century new force is given to it by the pious Mos- * See Josephus, "Antiquities," 1, 1, chap, ii ; Clement, "Epist.," 1; Cyril, "Hieros.

Speaking of the town of Segor, near the salt region, he says that the proper translation of its name is " Hell " ; and of the lake he says, " Its waters are hot, even as though the place stood over hell-fire." In the crusading period, immediately following, all the legends hurst forth more brilliantly than ever. The first of these new travelers who makes careful statements is Fulk of Chartres, who in 1100 accompanied King Baldwin to the Dead Sea and saw many wonders ; but, though he visited the salt region of Usdum, he makes no mention of the salt pillar : evi- dently he had fallen on evil times ; the older statues had probably been washed away, and no new one had happened to be washed out of the rocks just at that period. But his misfortune was more than made up by the triumphant experience of a far more famous traveler, half a century later — Rabbi Benjamin of Tudela. Rabbi Benjamin finds new evidences of miracle in the Dead Sea, and develops to a still higher point the myth and legend of the salt statue of Lot's wife, enriching the world with the state- ment that it was steadily and miraculously renewed ; that, though the cattle of the region licked its surface, it never grew smaller. Again a thrill of joy went through the monasteries and pulpits of Christendom at this increasing "evidence of the truth of Scripture." Toward the end of the thirteenth century there appeared in Palestine a traveler superior to most before or since — Count Burchard, monk of Mount Sion. He had the advantage of know- ing something of Arabic, and his writings show him to have been observant and thoughtful. No statue of Lot's wife appears to have been washed clean of the salt rock during his visit, but he takes it for granted that the Dead Sea is " the mouth of hell," and that the vapor rising from it is the smoke from Satan's furnaces. These ideas seem to have become part of the common stock, for Ernoul, who traveled to the Dead Sea during the same century, always speaks of it as the " Sea of Devils." Near the beginning of the fourteenth century came a traveler of far wider influence — Sir John Maundeville. In the various editions of the book ascribed to him, myths and legends of the Dead Sea and of the pillar of salt — old and new — burst forth into wonderful luxuriance. He brings news of a woman changed into an enormous dragon ; of a monster who be- sought a monk to cast out the devil from him, and who had horns on his head, which horns were shown Maundeville by the monk Bede, see his " De Locis Sanctis " in Tobler's " Itinera," i, p. 228.

He gives full details of the phoenix rising from its own ashes. But all culminates at the Dead Sea. He tells us that masses of fiery matter are every day thrown up from it as large as a horse ; that, though it contains no living thing, it has been shown that men thrown into it can not die ; and finally, as if to prove the worthlessness of devout testimony to the miraculous, he says : " And whoever throws a piece of iron therein, it floats ; and whoever throws a feather therein, it sinks to the bottom ; and, because that is contrary to nature, I was not willing to believe it until I saw it." He of course mentions Lot's wife, and says that the pillar of salt " stands there to-day," and " has a right salty taste." Great injustice has been done to Maundeville in holding him a liar of the first magnitude. Never was man further from the thought of lying. He simply abhorred skepticism, and thought it meritorious to believe all pious legends. The ideal Maundeville was a man of overmastering faith, and resembled Tertullian in believing things " because they are impossible " ; he was entirely conscientious; the solemn ending of the book shows that he listened, observed, and wrote under the deepest conviction, and those who re-edited his book were probably just as honest in add- ing the later stories of pious travelers. The " Travels of Sir John Maundeville," thus appealing to the popular heart, were most widely read in the monasteries and re- peated among the people. Innumerable copies were made in manuscript, and finally in print, and so the old myths received a new life.* In the fifteenth century wonders were increased.

For Maundeville I have compared several editions, especially those in the " Reyssebuch," in Canisius and in Wright, with Ilalliwell's reprint and with the rare Strasburg edition of 1484 in the Cornell Univer- sity Library : the whole statement regarding the experiment with iron and feathers is given differently in different copies. The statement that he saw the feathers sink and the iron Bwim is made in the Reyssebuch edition, Frankfort, 1584. The story, like the saints' legends, evidently grew as time went on, but is none the less interesting as showing the general credulity. Since writing the above I have been glad to find my view of Maunde- ville's honesty confirmed by the Rev. Dr. Robinson, and by Mr. Gage in his edition of Hit- ter's "Palestine." NEW CHAPTERS IN THE WARFARE OF SCIENCE. 451 a statement which is the result of the theological reasoning of centuries, and especially interesting as a typical example of the theological method in contrast with the scientific. He could not understand how the blessed waters of the Jordan could "be allowed to mingle with the accursed waters of the Dead Sea. In spite, then, of the eye of sense, he beheld the water with the eye of faith, and calmly announced that the Jordan water passes through the sea, but that the two masses of water are not mingled. As to the salt statue of Lot's wife, he declares it to be still existing ; and, copying a table of indulgences granted by the Church to pious pilgrims, he puts down the visit to the salt statue as giving an indulgence of seven years. Toward the end of the century we have another traveler yet more influential, Bernard of Breydenbach, Dean of Mainz. His book of travels was published in 1486, at the famous press of Schoeffer, and in various translations it was spread through Europe, exercising an influence wide and deep. His first im- portant notice of the Dead Sea is as follows : " In this, Tirus the serpent is found, and from him the Tiriac medicine is made. He is blind, and so full of venom that there is no remedy for his bite except cutting off the bitten part. He can only be taken by strik- ing him and making him angry ; then his venom flies into his head and tail." Breydenbach calls the Dead Sea " the chimney of hell," and repeats the old story as to the miraculous solvent for its bitumen. He, too, makes the statement that the holy water of the Jordan does not mingle with the accursed water of the infernal sea ; but increases the miracle which Caumont had an- nounced by saying that, although the waters appear to come together, the Jordan is really absorbed in the earth before it reaches the sea. As to Lot's wife, various travelers at that time had various fortunes. Some, like Caumont and Breydenbach, took her con- tinued existence for granted ; some, like Count John of Solms, saw her and were greatly edified ; some, like Hans Werli, tried to find her and could not, but, like St. Silvia, a thousand years before, were none the less edified by the idea that, for some inscru- table purpose, the sea had been allowed to hide her from them ; some found her larger than they expected, even forty feet high, as was the salt pillar which happened to be standing at the visit of Commander Lynch in 1848 ; but this only added a new proof to the miracle, for the text was remembered, " There were giants in those days." Out of the mass of works of pilgrims during the fifteenth cent- ury I select just one more as typical of the theological view then dominant, and this is the noted book of Felix Fabri, a preaching friar of Ulm. 452 THE POPULAR SCIENCE MONTHLY. I select him, because even so eminent an authority in our own time as Dr. Edward Robinson declares him to have been the most thorough, thoughtful, and enlightened traveler of that century. Fabri is greatly impressed by the wonders of the Dead Sea, and typical of his honesty influenced by faith is his account of the Dead Sea fruit ; he describes it with almost perfect accuracy, but adds the statement that when mature it is " filled with ashes and cinders." As to the salt statue, he says : " We saw the place between the sea and Mount Segor, but could not see the statue itself because we were too far distant to see anything of human size ; but we saw it with firm faith, because we believed Scripture, which speaks of it ; and we were filled with wonder." To sustain absolute faith in the statue he reminds his readers that " God is able even of these stones to raise up seed to Abra- ham," and goes into a long argument, discussing such transforma- tions as those of King Atlas and Pygmalion's statue, with a mul- titude of others, winding up with the case, given in the miracles of St. Jerome, of a heretic who was changed into a log of wood, which was then burned. He gives a statement of the Hebrews that Lot's wife received her peculiar punishment because she had refused to add salt to the food of the angels when they visited her, and he preaches a short sermon in which he says that, as salt is the condiment of food, so the salt statue of Lot's wife " gives us a condiment of wisdom." * There were indeed many discrepancies in the testimony of travelers regarding the salt pillar — so many, in fact, that at a later period the learned Dom Calmet acknowledged that they shook his belief in the whole matter ; but, during this earlier time, under the complete sway of the theological spirit, these difficulties only gave new and more glorious opportunities for faith. For, if a considerable interval occurred between the washing of one salt pillar out of existence and the washing of another into existence, the idea arose that the statue, by virtue of the soul which still remained in it, had departed on some mysterious excur- sion ; did it happen that one statue was washed out one year in one place and another statue another year in another place, this difficulty was surmounted by believing that Lot's wife still walked about ; did it happen that a salt column was undermined by the rains and fell, this was believed to be but another sign of life ; did * For Bernhard of Breydenbach, see marked pages in the Latin edition, Mentz, 1486, in the White collection, Cornell University, also in German edition in the " Reyssebuch " ; for John of Solrns, Werli, and the like, see the " Reyssebuch," which gives a full text of their travels.

NEW CHAPTERS IN THE WARFARE OF SCIENCE. 453 a pillar happen to be covered in part by the sea, this was enough to arouse the belief that the statue from time to time descended into the Dead Sea depths — possibly to satisfy that old fatal curiosity regarding her former neighbors ; did some smaller block of salt happen to be washed out near the statue, it was believed that a household dog, also transformed into salt, had followed her back from beneath the deep ; did more statues than one appear at one time, that simply made the mystery more impressive. In facts now so easy of scientific explanation the theologians found wonderful food for discussion. One great question among them was whether the soul of Lot's wife did really remain in the statue. On one side it was insisted that, as Holy Scripture declares that Lot's wife was changed into a pillar of salt, and as she was necessarily made up of a soul and a body, the soul must have become part of the statue. This argu- ment was clinched by citing that passage in the Book of Wisdom in which the salt pillar is declared to be still standing as " the monument of an unbelieving soul." On the other hand, it was insisted that the soul of the woman must have been incorporeal and immortal, and hence could not have been changed into a sub- stance corporeal and mortal. Naturally, to this it would be answered that the salt pillar was no more corporeal than the ordinary materials of the human body, and that it had been made miraculously immortal, and that " with God all things are possi- ble." Thus long vistas of theological discussion were opened.* As we enter the sixteenth century the Dead Sea myths, and especially the legends of Lot's wife, are still growing. In 1507 Father Anselm of the Minorites declares that the sea sometimes covers the feet of the statue, sometimes the legs, sometimes the whole body. In 1555 Gabriel Giraudet, priest at Puy, journeyed through Palestine. His faith was robust, and his attitude toward the myths of the Dead Sea is seen by his declaration that its waters are so foul that one can smell them at a distance of three leagues ; that straw, hay, or feathers thrown into them will sink, but that iron and other metals will float ; that criminals have been kept in them three or four days and could not drown. As to Lot's wife, he says that he found her " lying there, her back toward heaven, converted into salt stone ; for I touched her, scratched her, and put a piece of her into my mouth, and she tasted salt." At the center of all these legends we see, then, the idea that, though there were no living beasts in the Dead Sea, the people of the overwhelmed cities were still living beneath its waters, prob- * For a brief statement of the main arguments for and against the idea that the soul of Lot's wife remained within the salt statue, see Cornelius a Lapide, " Commentarius in Pentateuchum," Antwerp, 1697, chap. xix. 454 THE POPULAR SCIENCE MONTHLY, ably in hell ; that there was life in the salt statue ; and that it was still curious regarding its old neighbors. Hence such travelers in the latter years of the century as Count Albert of Lowenstein and Prince Nicholas Radzivill are not at all weakened in faith by failing to find the statue ; what the former is capable of believing is seen by his statement that in a certain cemetery at Cairo during one night in the year the dead thrust forth their feet, hands, limbs, and even rise wholly from their graves. There seemed, then, no limit to these pious beliefs. The idea that there is merit in credulity, with the love of myth-making and miracle-mongering, constantly made them larger. Nor did the Protestant Reformation, which now came in, diminish them at first ; it rather strengthened them and fixed them more firmly in the popular mind. They seemed destined to last forever. How they were thus strengthened at first, under Protestantism, and how they were finally dissolved away in the atmosphere of scien- tific thought, will be shown in the following chapter.* -♦*♦- THE LOCALIZATION OF INDUSTRIES. Bt J. J. MENZIES. AMONG the ancient peoples of the far East any exchange of productions was necessarily on a small scale. Means of transport were limited — by land, to the backs of men and animals ; and by water, to rivers and such lakes or inland seas as could be safely navigated by small and rudely constructed boats. Most commodities were raised, manufactured, and consumed within very restricted areas, with little division of labor ; and excepting nat- urally abundant agricultural products and domestic animals were, therefore, inferior and expensive, and men could only accommo- date themselves to variations in crops by lavish consumption when they were abundant, and by starvation when they were scanty. In later times, the art of navigation was so far improved as to ex- tend trading along the shores of the Mediterranean, and eventu- ally across it, by which means countries situated round about that great inland sea were brought into close communication with each other, a rapid advance in the arts and sciences resulted, countries hitherto little known were explored, a larger exchange of com- modities was effected, and surpluses and deficits were made to bal- * For Father Anselm, see his " Descriptio Terra?

THE LOCALIZATION OF INDUSTRIES. 455 ance each other. Still later navigation reached to all the shores of the Old World, and finally into the Western hemisphere. With every addition to the field of human knowledge and enter- prise there was a corresponding increase in the volume of ex- changes and in the variety of manufactures and useful conven- iences. Each country and district parted with that which it had in superabundance, or was particularly skilled in producing, for goods that were scarce or wanting to it, or that its own artificers were not accustomed to manufacture. The same system of operations continues extending at the present day, and may do so apparently for an indefinite time. Every new country brought tinder cultivation, every new dis- covery of the treasures of the earth and waters, every new ap- pliance adding to our powers and to our facilities of communi- cation, and even every increase in itself in the sum of trading operations, forms the basis of new exchanges to mutual advan- tage; for the greater the quantities the smaller the profit at which it will pay to exchange them. Experience keeps con- stantly adding to our knowledge of the special advantages of each locality, and every free movement of trade and industry increases the sum of their usefulness to the human race. Scar- city of food can no longer exist among nations that have kept abreast of this economical revolution. The aggregate of com- forts and luxuries generally attainable has multiplied enor- mously, and the mere operations of exchange give directly and indirectly steady and profitable employment to vast numbers. Nor is this freer exchange of commodities and of ideas attended, as many suppose, by increased competition between men and nations, for it is accompanied by a better and more wide-spread division of labor, and men by degrees cease to produce these arti- cles in which they are manifestly at a disadvantage, and the dis- posal of which entails loss and disappointment. Those who doubt the advantages of this universal, world-wide intercourse and exchange are bound in consistency to advocate the reversion of society not merely to any earlier stage in its development, but to that state of things which preceded its initiation — that is, to pure and simple cannibalism ; for an argument that is good against one step in this march of progress is equally good against another. As it is certain, too, that this same movement, in spite of wars and governmental interferences, is constant and resistless, there can be no more important question than how best to con- form to and profit by it, which we may learn by observing how men and nations naturally find their most suitable and profitable occupations. The general principles determining the employment of the soil of different countries and localities are tolerably simple. Com- 456 THE POPULAR SCIENCE MONTHLY. mon, bulky, and perishable articles are naturally produced as near as possible to the places of consumption, though improve- ments enabling them to be more easily and cheaply transported render them more available for distant markets. Such are the compression and baling of hay, the conveyance of dead meats in refrigerated chambers, of live animals in specially adapted wag- ons and steamships, and of ordinary fresh fruits and vegetables by express trains. More valuable articles and luxuries, such as the finer fruits, sugar, tobacco, and cotton, the cost of transport of which is relatively less important, can and often must be pro- duced in localities specially adapted to them at greater distances from the places of their eventual consumption. Dried fruits are more fitted for distant and uncertain markets than green fruits. Other generally esteemed articles, such as silk, tea, and the finer wines, naturally monopolize the limited areas capable of produc- ing them. On the other hand, as almost any part of the world can grow wheat and the ordinary small grains by the employ- ment of a comparatively limited capital, as the cost of transporting them is inconsiderable, as they are not liable to spoil, and as the enormous quantities in which they are handled and the universal competition among producers of them enable and necessitate their being turned over at the minimum profits, the growth of these indispensable staples is left to the newest, the poorest, and the most remote countries, and to those parts of other countries for which no better employment can be found. A decline in the production of these articles is a sign, beyond doubt, of the increasing wealth of a country, and that it has found better employments for its capital and labor. This is especially noticeable in England, Germany, France, and our own Eastern States ; and California also, it may be noted, is discontinuing the production of grain as rapidly as she can find a market for her higher class articles. A still more decided move in the same direction is only restrained in England by the uncertainty of the climate, and the consequent danger of devoting too great an area to pasturage, green crops, fruit, or hops, since an excess of drought is adverse to the first two, and an excess of moisture to the others. The future order of cultiva- tion in the United States is dependent chiefly on the development by irrigation of the vast arid regions of the West, and upon the nature of the resources which may thereby be disclosed, as also upon the description and extent of the trade just beginning between our Pacific coast, Japan, China, Australia, and New Zealand, and that to open up later with the East by the Central American inter- oceanic canal. It is already certain that the convenient position of California for this trade, her variety of climate and elevation, and resulting adaptability for a great choice of productions, insures for her, through the extension of irrigation, a great and THE LOCALIZATION OF INDUSTRIES. 457 distinctive future. If her wine trade be not as yet as prosperous as she could wish, no one need be surprised at this who has re- marked the specialties of character in the different European wines, and considered the centuries of labor and application that have been required to evolve these varied types as the most appro- priate to their several localities, as also the great capital employed at low rates of interest in maturing these wines and in educating the tastes of consumers thereto. The production of wool on a large scale is a natural resource of mountainous countries and of regions distant from centers of population, as we see in Wales, portions of Scotland, Germany, and the United States. The marked devotion of Australia to this industry is due to the sud- den opening of her unlimited territories, to the nature of her climate, suitable for the rearing of sheep, and to her rainfall, too limited and uncertain for profitable cultivation. Added to these causes is her remoteness from other countries, which, mak- ing impossible the export of the animals themselves, dead or alive, on an adequate scale, has allowed her flocks to increase almost unchecked. As we already saw in the case of the common and bulky natu- ral products, so it is with the corresponding class of manufactured goods ; they can not well bear a long and expensive carriage, and therefore, other things being equal, are naturally produced as near as possible to their places of consumption. As in the United States there are numerous contiguous deposits of coal and iron, those most convenient to the large centers of population have been in the mean time utilized, both for fuel and for the heavy iron manufactures, rails, pipes, and machinery, that the various purposes of such communities call for on a great scale. When such articles must necessarily be sent to long distances, those points most convenient to water-carriage are naturally preferred for their production. Pittsburgh is a notable instance of this, also the English, Scotch, Welsh, and Australian coal ports, from which this indispensable mineral is shipped to every part of the world. When especially it is desirable for some manufactures to mix the heavier metals of different countries, such operations must neces- sarily take place at or near some convenient port. Thus, tin mined in Cornwall is taken to Swansea, the nearest port having iron- works, when required for making tin plates, and imported ores are, by the use of the adjacent coal, also smelted there, as well as at various coal ports in the northwest coast of England and else- where. The convenience of both coal and iron has made the river Clyde the chief seat of iron ship-building, just as its local timber made Boston that of wooden ship-building. Makers of boilers, engines, and heavy machinery at Manchester, England, have also discovered that even the thirty miles of rail carriage to Liverpool, 45* THE POPULAR SCIENCE MONTHLY. and the rehandling there, handicap them in competition with Glasgow shippers of the same articles, which is one of the chief reasons for the construction, now in progress, of the Manchester ship-canal. In countries where deposits of coal and iron are com- paratively rare, as in France, Germany, and elsewhere, the favored spots necessarily become themselves the chief centers of manu- facture and population. Furniture is a rather bulky and expen- sive article to move about, and its manufacture, for use through a large portion of the United States, has found an appropriate and central position at Grand Rapids, Mich., where the most useful native timbers and water-power are in abundance. The lighter metal and wood manufactures, the textiles, leather, pottery, and miscellaneous small wares, in which the cost of trans- port is relatively less important, are determined, as to their loca- tion, by a much greater complexity of conditions, and the general rules on this point are subject, in their case, to variation from specially dominant influences. In order to combine the most ob- vious advantages, they should not be situated too far from a sup- ply of coal and iron, should be convenient to the sources of their raw material, whether home or foreign, and to the markets where their finished products are expected to find a sale. While, too, each article and department of manufacture will usually succeed best around a center of its own, where a skilled and adapted popu- lation has become settled, it is still more important that all should be conveniently clustered for mutual assistance. While these conditions are more or less generally complied with in all great manufacturing countries, they are most completely so in Great Britain, partly by reason of its natural facilities, partly owing to the absence of any fiscal interference by their own Government. Thus it may be observed that the location of the cotton manufact- ure in Lancashire, of the woolen in Yorkshire, and of the lighter metal and miscellaneous in and around Birmingham, is in compli- ance with those principles, as well as the subdivision and speciali- zation of all these various industries, many of which and similar ones may also be found in Scotland, which, to a certain extent, is a smaller independent center. Subject to necessary geographical differences, the location and arrangement of similar manufactures in the United States and on the European continent follows as near- ly as possible the same conditions. Only in New England had we in existence a population capable of successfully undertaking the production of the great variety of those articles when prematurely called for by the imposition of our high protective tariff on their importation ; and the situation of that country, in a corner, as it were, of our territory, and without local supplies of coal and iron, is not all that could be desired for the purpose. True, its sea- ports, convenient for coastwise navigation, its abundant water- THE LOCALIZATION OF INDUSTRIES. 459 power, and its supply of native wool and timber, to a great extent set off these disadvantages, though probably not completely. The free commercial policy of Great Britain, united with the combination in a small, centrally situated space of country of all the most desirable facilities, marks her out as the greatest of international manufacturing and trading countries. Her manu- facturers have perfect liberty to purchase their raw or partially manufactured materials in the best and cheapest markets ; and their constant intercourse with all parts of the world keeps them informed of every new invention and resource. Their own home market is one of the most important, and, having no pro- tection therein, they know at once when they are excelled in the production of any article, and whether it is owing to any natural or acquired advantage, so that among them there is very little waste of effort. Extent of capital hitherto undreamed of, ready to back their efforts abroad by investments in every promising enterprise, also enables them to command a preference in many undeveloped and poor countries. Yet it would be a great error to suppose that there do not exist in many other countries advan- tages sufficient to enable them also to carry on a large export busi- ness in manufactured goods. All are able to utilize some native materials and to save the intermediate profits and carriages upon foreign wares, and without doubt there are many wants that are best understood by the native manufacturers. Crippled as their producers are by fiscal restrictions upon their purchases and com- binations, several of them are even now able to sell their wares largely to England herself. The artisans of the European conti- nent are willing to work during a greater number of hours daily and for lower wages than those of Great Britain, and the cost of production is thereby diminished ; and there are always in each country some advantages peculiar to itself and its population. Thus, France has a specialty in artistic taste, which enables her to supply the English market with most of its silks and ornamental objects, as well as with large quantities of fine woolen fabrics. Germany, the best educated country in the world, excels in ap- plied science, as in the working of metals and stained glass ; and the United States in labor-economizing apparatus, such as agri- cultural, sewing, and printing machines. Belgium has supplied wrought-iron girders for the roofs of English and Scotch rail- way stations. England also exports large quantities of partially manufactured goods, such as yarns, chemicals, and pig-iron, show- ing that the importing countries have, in various ways, superior facilities for the finishing processes. She also has need of the co-operation of other countries for the perfecting of her own wares. Thus, the finest flax grown in the north of Ireland, in order to attain its highest quality, must be sent to Belgium to be 460 THE POPULAR SCIENCE MONTHLY. steeped in the water of a certain river. Returning from there, it is spun into superfine yarns by the best machinery and in the naturally adapted moist climate of Belfast. At that stage the product is again sent back to Belgium, where it is woven into gossamer-like cambrics, in low, damp cellars, and under condi- tions that would not be agreeable to the north of Ireland artisan, and the work of the Belgian hand-loom weaver must then be carried back to be bleached under the dripping skies of the Green Isle. England is, besides, herself the largest and readiest buyer of all improved articles of necessity and luxury, from whatever source arriving; and, while usually the first to open up new markets, in none does she lay claim to any exclusive privilege. There is, indeed, ample room in the natural economy of pro- duction for the services of all nations, and none need stand idle. Co-operation, not hostility and jealousy, should be the watchword of modern industrial enterprise. We ought, in the interest of pro- ducer and consumer alike, to remove all fiscal shackles from our trade and manufactures. European governments, hampered with the expenses of an all-devouring militarism, may be unable to abandon any source of revenue, however demoralizing in its inci- dence or costly in its collection. They may also fear the effects upon their own stability of even a temporary disturbance of ex- isting employments. But neither of these objections can be of any weight with a nation perplexed only with the disposal of its surplus revenues, and whose reposing might need fear no foreign attack. In the enormous extent of our partially developed terri- torial resources, and no less in our wealth of inventiveness, now but half utilized, there can be no scarcity of employment for capital and labor, nor can we find any such profitable investment for our hoarded millions as the release of our capitalists and artisans, by just indemnities and pensions, from the demoralizing servitude of state-supported industries. In the past we have misdirected their energies and squandered their resources, and we owe them some compensation. Let us all make a new start by working in alliance with Nature, and no longer in ignorant opposition to her. Let each industry freely settle where it may, in our territory or out of it, and within the lifetime of many already middle-aged we shall see progress in the wealth of our country, and in the growth and contentment of our population, far surpassing all our previous experience. A new view into the conditions and international relations of the remote past is given by Dr. Lehmann, of Berlin, in a paper on " Ancient Metrology." His showing that the Egyptian system of weights and measures, instead of being the origin of that of Babylonia, presupposes the sexagesimal system of the latter, if con- firmed, would indicate the existence of commercial intercourse between Babylonia and Egypt at a time of which we have at present no contemporaneous records. EVOLUTION OF THE MODERN RAILWAY BRIDGE. 461 THE EVOLUTION" OF THE MODERN RAILWAY BRIDGE. By Peof. CHAKLES DAVIS JAMESON, OF THE STATE UNIVEESITY OF IOWA. ABRIDGE is a structure over a river, ravine, or other open- ing, for the purpose of sustaining a moving load. This, in the case of a railroad bridge, consists of a heavy locomotive and train coming on at one end, rushing rapidly over the bridge, and off at the other end. This fact, that the load to which bridges are subjected is a moving load applied for only a short period of time and then removed, is a most important factor to be considered in calculating the necessary strength of the various members, as the strain produced in any piece of material by the application of a load is nearly doubled when the load is applied quickly as com- pared with that produced by the same load when applied grad- ually. Bridges may be divided into the following classes : 1. The beam or girder. 2. The framed truss. 3. The arch. 4. The sus- pension bridge. The most ordinary form which we see in this country, and the one most generally used for the purpose of railway bridges, is the framed truss, and that is the one the development of which it is our purpose to show. The one point to be carefully studied in all bridge construc- tion is economy — that is, to get as much strength with as little material as possible; in other words, the maximum amount of strength with the minimum amount of material. The simplest method of crossing any opening where the dimen- sions of the opening are not so great, or the load so heavy, as to forbid its use, is by means of a plank placed from one side to the other, making the plank of such a length that the ends may have sufficient bearing upon each side of the opening (Fig. 1). Fiff.l In crossing an opening by means of a simple plank or beam, supposing we make the beam large enough, it answers every pur- pose and will hold up the required load. But in this there is great waste of material. We will take, for example, a plank twelve inches wide, and three inches deep, over an eighteen-foot opening — that is, the plank would have to be about twenty-one or twenty-two feet long, in order to allow the ends sufficient bearing surface upon the masonry on each side. This plank would hold up a certain amount of weight, but, as the weight is increased, in 462 THE POPULAR SCIENCE MONTHLY. a very short time the plank would begin to "bend and buckle in the center. In order to increase the strength of this primitive bridge, we could place another plank beside it, making the bridge twenty- four inches wide, and, if the passing load were made to bear upon the entire width of this bridge, of course the bridge would bear just twice as much as one plank; but, in order to double the strength of the bridge, we have also doubled the amount of material necessary in its construction, and therefore have not in any way increased the economy. This system might be carried on to infinity, and almost any amount of required strength be obtained by placing a sufficient number of planks one beside the other. But, returning again to the two planks, instead of placing them one beside the other, sup- pose we place one plank on top of the other, and nail them to- gether firmly, so that they shall act as one plank (Fig. 2). We 1 5555555555555=5555555555= =55 = Fig. 2 then have a bridge eighteen feet long, twelve inches wide, and six inches deep. In this bridge we have exactly the same amount of material we had when the two planks were placed side by side, but we have four times as strong a bridge instead of only twice ; that is, we have doubled the amount of material, but we have multiplied the strength by four. If one plank would hold up one hundred pounds on the center, then the two planks placed side by side would hold up two hun- dred pounds ; while, placing the planks one on top of the other, and nailing them firmly together, they would hold up four hun- dred pounds. In this way we see that, in order to increase the strength of the bridge or beam faster than we increase the amount of material, the increased amount of material should go into the depth of the beam and not into the width of it. This is one of the first principles in the resistance of material, that the strength of a beam varies directly as the width — that is, if we make the beam twice as wide, it will hold twice as much ; and that the strength varies as the square of the depth — that is, if we make it twice as deep, it will hold up four times as much. If we make it three times as deep, it will hold up nine times as much of a load. So that you can readily understand that, in order to in- crease the strength of the bridge or beam without increasing the material in the same proportion, the increased amount of material should be put into the depth and not into the width. We now have a bridge twelve inches wide and six inches deep, which will hold up four times as much as our original bridge, twelve inches wide and three inches deep, and the amount of material is simply doubled. To advance one step beyond this, EVOLUTION OF THE MODERN RAILWAY BRIDGE. 463 suppose we take one of the planks and stand it up edgewise, and then place the other plank upon its flat side upon the top of this, as shown in Fig. 3, and nail the planks firmly together. We now have a bridge twelve inches wide, as we originally had, but fifteen inches deep, or what is known as the T-bar or girder, and the only difficulty about this bridge is the trouble in making it stand up ; being so much higher than it is wide, it has a great tendency to tip over. But supposing the planks are made to stand in this shape, which is a simple matter, we then have a bridge fifteen inches deep, which will hold about seven times as much load as the original plank. Of course, if the bridge were made fifteen inches deep and the same width, that is, twelve inches wide, it would hold twenty-five times as much as the original bridge ; but by turning one of the planks upon the edge we have increased the depth and decreased the breadth, so that the breadth of the bridge under the top plank is only one fourth of what it was before, and the total strength of the bridge is from seven to eight times that of the original plank. Now, in order to obviate some of the difficulty in making this bridge stand up, suppose we take the plank that is upon the edge and make two planks, each of them twelve inches wide but only an inch and a half thick, and then nail the floor plank upon the edges of this, making an inverted box, as shown in Fig. 4. We then have a bridge that there is no trouble in making stand, as it has twelve inches of bearing surface, and we have the same amount of strength as when it was in the shape of the T-bar, and we have what is technically known as the U-bar or channel-bar. In this U-bar there is this trouble : that, having the sides only an inch and a half thick and twelve inches deep, there is a tend- ency to bend in the sides — that is, a tendency to give sidewise ; and in order to obviate this we take the top plank and split it in two, making two planks twelve inches wide and an inch and a half thick. Nail one on the top and the other on the bottom : we get what is called a box girder (Fig. 5), and which has about nine- teen times the strength of the original three-inch plank and only double the amount of material. So far we have considered our bridge as being only twelve 464 THE POPULAR SCIENCE MONTHLY. inches wide. We now wish a bridge wider than this, but with no more material in it except what may be needed in order to make the floor. Suppose we take the top and bottom plank of this box girder, cut them in two lengthwise, making out of each two planks six inches wide instead of twelve, and we fasten these upon each of the vertical planks, as shown in the drawing. We then have what is technically known as an I-bar, or flanged girder (Fig. 6). Provided these flanged girders are so braced as to pre- vent their bending sideways, the two flanged girders are of exactly the same strength as the box girder, and, as you see, can be placed at any distance apart, and the floor simply placed on top of them or on the lower flange, and we have a bridge as wide as we wish, with the strength of the box girder. This I-bar, or flanged girder, is one of the most generally used forms of construction for bridges of short spans. So far we have considered the material used to be simply wood, but I-bars are now made of iron or steel, and within the last few Fig. 6 A. years entirely of steel, owing to the fact that the improved method of making steel has rendered it even cheaper than wrought iron. Let Fig. 6 represent a side-view of the flanged girder, or I-bar, of which Fig. 6 A is an end-view. Suppose this beam to be supported at each end and a load placed upon the center. Then the tendency of that load would be to bend the beam down in the shape of the dotted line, and, in case the load is sufficient, it would break in that way. Before the breaking-point is reached the top and bottom of this beam are subjected to totally opposite classes of strain, as you will see. If you bend the beam, the tendency in the bottom of it is to pull the beam apart, or, in technical language, the bottom flange of the beam is in tension — tension being the force which tends to pull apart the particles of the beam. Thus, if you take a string fastened at one end, and hang a weight on the other end, the string is in tension, the action of the weight being to pull the particles of the string apart. The top flange of the beam is in compression — that is, the EVOLUTION OF THE MODERN RAILWAY BRIDGE. 465 particles of which the beam is composed are forced together. It is the same strain obtained if you take a vertical post and put a weight on top of it ; that weight tends to force together the parti- cles of the post, and the post is said to be in compression. It is well to get a thorough understanding of these two kinds of strains, as they are the principal strains that have to be considered in all bridge-building. There is a point between the top and bot- tom of the beam at which the character of the strain changes from compression into tension, where there is no strain at all, and the amount of strain in the beam decreases from the outside toward the center until this zero-point, or neutral plane, is reached ; and, as the greater part of the strain comes upon that portion of the beam farthest from the center, you will at once see the economy and necessity of placing as much of the material as far from the center as possible — that is, placing the material where it is going to do the most work, and this is what has led to the adoption of the flanged girder, or I-beam, as a favorite method of construction. The principal part of the material is placed at the two outside edges of the beam where the strain is the greatest, and the amount of material between these two outside flanges is simply enough to keep the flanges apart. As the size of the opening to be crossed increases, the size of the flanged girder necessary to hold up a given load increases, so that in a very short time the piece of iron or steel necessary becomes so large as to make it almost impossible to handle if it is all in one piece, and also a great deal of the material in the flanged girder is absolutely of no use — that is, a great deal of it can be cut away and used to more advantage in other places. This leads us at once to the framed truss or framed girder. There is one thing in connection with framed trusses to which I wish to call your attention, and that is, the whole foundation of the framed truss is based upon a triangle. You will readily see the object of this. Suppose four pieces of timber are framed to- J L gether, as shown in the drawing (Fig. 7), in the form of a square or rectangle. Then any strain coming upon one side of this rect- angle tends to change the form of the figure, and, unless the joints are made perfectly stiff, the rectangle is changed to the shape shown in Fig. 8, where every piece is of its original length, and VOL. XXXVI. 30 466 THE POPULAR SCIENCE MONTHLY. simply the angles have been changed. Now, suppose we divide this rectangle, by means of a brace or tie, into two triangles. Then not one of these timbers can be moved, or the form of the rectangle changed in any way, without lengthening or shortening the diagonal which divides it into triangles, and, therefore, the rectangle with the brace and tie forms a perfectly rigid figure (Fig. 9). In other words, the triangle is the only figure the form of which can not be changed without changing the length of one of the sides ; and thus any truss, to be perfectly braced and able to withstand any strains that come upon it, must be framed so as to be divided into a series of triangles. Returning to our original beam thrown across an opening, we will suppose that we have a beam long enough and strong enough with the required load to cross an opening eighteen feet wide, and that we have an opening thirty-six feet wide which we wish to cross. That could be done by building a pier in the center of the opening and dividing it into two openings, each eighteen feet, as shown in Fig. 10 ; but, in the case of a bridge over a road or over a small river, it would not be advisable to block up the way by this pier, and some other method must be found to support the two inner ends of the beams. The simplest plan of doing it is shown in Fig. 11. Taking two beams that are each slightly Fig. 10 a 1 rz^si m jm >. KING POST Fig. 11 longer than eighteen feet, we throw them across the opening, as shown in Fig. 11. These two beams meet at the angle, the apex, A, of which is up, and, if the two lower ends are kept from sliding apart, will stand in that position. Now, if from the angle where these two beams meet we let down a rope or iron rod, run out the floor beams eighteen feet long, and connect the inner end of each to this rope or rod, we have a bridge covering an open- ing thirty-six feet long — that is, one end of each floor beam rests upon the ground, the other end is sustained by the rope or EVOLUTION OF THE MODERN RAILWAY BRIDGE. 467 iron rod, and all the weight upon these ends of the beams passes up the rod, and then conies down the two diagonal beams to the abutments. The one thing necessary in this is that the lower ends of the two diagonal beams shall be so fixed as to make it impossible for them to slip out in the direction of the arrows, and this object is usually attained by making the floor stringers serve as a tie to hold them together. In the drawings, the full black lines are in compression and the dotted lines are in tension. Thus, you see the vertical rod or rope in the center is in tension — that is, a weight being at W, all of that weight comes directly upon the rod and is carried to the apex, A ; then half of it passes to each side down the inclined braces, and they are in compression. The tendency at the foot of these braces is for them to slip out in the direction of the arrows. They are held together by the tie- rod or floor stringers, which are in tension. In regard to tension and compression, you may get a better comprehension of them if you understand that a cord or rope can be used for any member of a bridge that is in tension, while a post or some stiff piece of timber or iron is necessary for anything in compression — that is, in all these diagrams the dotted lines could be replaced by ropes or cords, while the full black lines are obliged to be iron or wooden posts or braces. You thus see that we have the simplest form of a framed truss. This form of truss is called the king-post truss. Now, as the width of the opening increases, the height of the posts would also have to increase, and in a very short time would get so high, and make the inclined braces so long, as to become unwieldy. In order to overcome this, after a certain height has been reached, instead of continuing the king-post higher, we simply cut it off and substitute two posts or rods in its place (Fig. 12). In this the QUEEN POST Fig. 12 length of span that can be covered with the same sized material is one half larger, and the bridge is divided into three panels, as they are called. A panel is one of any number of equal parts into which the truss of a bridge is divided by means of the posts or rods. This second truss is called the queen-post truss ; here also the full black lines are in compression and the dotted lines are in tension. As you will notice in this truss, which is also the case in 468 THE POPULAR SCIENCE MONTHLY. the flanged girder, the top part of the truss and the top flange are always in compression ; so the lower chord is always in tension, as the lower flange in the flanged girders. This principle is the same in all framed girders. Fig, 13 Either of these trusses can be inverted whenever it is desired, so that the truss comes below the floor, as shown in Figs. 13 and 14 ; the only difference that it makes is in the character of the strain that comes upon the different members of the truss. The vertical member in the upright truss is in tension, and when the truss is inverted it is in compression, as shown in the drawing. The braces become ties, and the floor stringers are in compression. Whenever it is desired to make the floor come upon the top of the truss, then the bottom chord or tie-rods can be omitted en- tirely, and the horizontal thrust taken by means of the masonry EVOLUTION OF THE MODERN RAILWAY BRIDGE. 469 abutments (Figs. 15 and 16). There the weight comes directly- down from the top of the bracing, and the lower end of the braces are held in place by the masonry abutments. From some combination of these trusses can be constructed any form of bridge, with the exception of the suspension bridge and the arch. By increasing the number of panels or by com- bining a number of king-post trusses (Figs. 17 and 18), we have what is known as the pony truss, and for short spans one that is used to a great extent on all railroads.

The ordi- nary railroad bridge is composed of simply two trusses, one upon each side. These trusses are connected at the top and bottom, and the train can either run over the top of the bridge, or through the bridge on the bottom chord. In the pony truss, the only distinctive feature is that the trusses are not deep enough to allow of their being fastened to- gether across the top, when the train runs through upon the bot- tom chord, and therefore they can only be used for very short 47° THE POPULAR SCIENCE MONTHLY. spans, and. it is considerable trouble to so brace them as to keep them in a true vertical plane. These pony trusses, however, when used as a deck bridge, that is, when the train runs on the top, can be braced so as to form a very firm bridge, and practically it is simply a box girder (Fig. 5). The members of a bridge at the top and bottom of each truss, either horizontal, inclined, or curved, are called chords ; that at the top is called the top chord (A B, Fig. 22), the bottom one, the bottom chord (CD, Fig. 22). In the bridges we are considering, they are usually parallel. The brace or strut is a compression member, and may be either vertical or inclined (E F, Figs. 21 and 22), the object of which is to keep the two chords apart. The tie is a tension member, and also may be either vertical or inclined (G H, Figs. 21 and 22). The lower chord being always in tension is sometimes called the strain- ing piece. E G HOWE TRUSS Fig. 21 PRATT TRUSS Fig. 22 In some types of bridges which we will take up at once there is no bottom chord (Fig. 19). We have what is called the Fink truss. As will be readily seen, it is merely a combination of the inverted king-post trusses, combined in such a way as to suit any required span. In this bridge the bottom chord is not in any way necessary to the proper construction of the truss, but in case of a long span it is usually put in as shown by the dotted line, not in any way to increase the strength of the truss, but simply to add to its stiffness and stability. The Fink truss was invented by Albert Fink, and manufactured for many years by the Louisville Bridge and Iron Company. For short spans, or what are usually called shore spans in many-span bridges, it is a most convenient and economical method of construction, and has been very much used. The top chord is in compression, as shown in the drawing, and is usually made of wood, although this is not by any means necessary. The posts, or vertical compression members, are usu- ally of iron, and the tension members consist of round iron rods, fastened by means of an eye and pin at the ends. EVOLUTION OF THE MODERN RAILWAY BRIDGE. 471 The next form of truss is that known as the Bolman truss (Fig. 20). In this also, as in the Fink truss, there is no bottom chord necessary. The distinctive characteristic of the Bolman truss is that from the lower end of each vertical compression member the tension members run directly to each abutment, differing in this respect from the Fink truss, where most of the tension members run across simply one or two panels of the bridge. In this way any load coming upon the top of one of the panels in the Bolman truss passes down the vertical compression member and is at once carried to the abutments by means of the tie-rods. Theoretically, this bridge is one of the most simple that can be constructed; but when the span becomes of any great length, the length of these tie-rods becomes so great as to render them unmanageable, and within very small limits they become impracticable for that reason. Hence, the Bolman truss has not been used to any considerable extent. By the addition of the bot- tom chord to support the floor timbers of the bridge, either the Bolman or the Fink bridge can be used as a through bridge as well as a deck bridge, although to achieve the utmost economy in their use they are both eminently deck bridges. We will now take up the different kinds of trusses that are used in ordinary railroad work, all of which are simply some combination of the king-post trusses, either upright or inverted. The first and most common form in this country is what is known as the Howe truss (Fig. 21). In this the braces are diagonal and the tension members are vertical. This form of truss has probably been built a hundred times more than any other form that is in use. It is not in every re- spect an economical truss ; but the reason of such general use is the fact that it is one of the most simple to construct. The full lines are those in compression, and are usually built of wood. In the Howe truss, the lower chord, which is in tension, is also built of wood, while the only iron- work about it is the vertical rods and cast-iron blocks for the ends of the post. You will thus see the advantages of this truss in a country where wood is very plenty and iron is scarce. The construction of the iron-work is very simple, and the parts are in pieces, so that they can be easily handled by one gang of men with the ordinary block and tackle. The angle blocks are all duplicates, so that, after a pattern has once been made, a great many similar pieces can be made from it ; and this, in the absence of skilled labor or proper shops for doing bridge work, is a great saving of time. In all Howe trusses a very large " factor of safety " has to be used in order to take into account the uncertain character of the wood. By a factor of safety we mean this : you have a given load which is to be supported by a bridge ; if all the material 47- THE POPULAR SCIENCE MONTHLY. used in that bridge were absolutely perfect, the size of each piece would have to be exactly large enough to bear its part of the strain, and no larger ; but as neither in iron or steel, and particu- larly in wood, can you calculate just exactly how many pounds of strain any particular piece will stand, in order to make it perfectly safe you use, in calculating the size of the bridge members, the load it is to bear multiplied by five, and sometimes even by ten, and then make the bridge theoretically strong enough to hold up this load — that is, five or ten times the amount of load that ever can come on it — and this five, or ten, or six, as the case may be, is called the factor of safety; that is, if all material used in the bridge were absolutely perfect, the bridge would hold up five or ten times as much as ever would come upon it ; and wherever a great deal of wood is used the factor of safety has to be very large, as the amount of strain that wood will bear is very uncer- tain, and varies under different circumstances. You will readily see that the Howe truss can be used either as a deck bridge or a through bridge, and remember that the Howe truss is the type of bridge that was generally used upon railroads so situated that wood was plenty and iron expensive, and without money enough to send a long distance for iron bridges ; and there have been some remarkable examples in this country of the dura- bility of Howe-truss bridges designed by ordinary carpenters without any technical education. As the price of iron decreased, in a very short time the lower chord of the Howe-truss bridge was made of iron instead of wood, as it was found to be much more economical, and it was then what is called a " combination bridge " ; that is, of wood and iron. The next form of bridge is what is called the " Pratt truss " (Fig. 22). The distinctive feature of this is that the compression members are vertical, while the tension members or ties are in- clined or diagonal. In this, the amount of iron, supposing the tension members to be of iron and the compression members of wood, is increased and the amount of wood is decreased. This was a very natural result as the price of iron decreased. In a short time the wooden posts were removed and iron posts substituted for them, and we then have an entire bridge of iron, in which the compression members are vertical and the tension members in- clined, and it is the most generally used form of iron bridge in this country ; it may be called the typical American railway bridge. The next form of truss that we will examine is what is known as the Warren triangular girder (Fig. 23). You will see that each of the pieces connecting the upper and lower chords acts both as a tie and a brace — that is, is subject to both compression and ten- sion. The only advantage that can be claimed for this bridge EVOLUTION OF THE MODERN RAILWAY BRIDGE. 473 is simplicity and a fewer number of parts than any other form of bridge truss ; but by thus reducing the number of parts we have in- creased the size of the parts that are used, and thus, to some extent, done away with the advantage. Each of the tie-braces, as they are called, crosses one panel, and the bridge is thus divided into bays two panels long. The vertical rods, as shown in the draw- WARREN TRIANGULAR TRUSS Fig. 23 ing, are not in any way necessary to the theoretically proper con- struction of the truss, but are simply put in to support the chord between the panel-points and make it able to bear the cross-strain that comes upon it from the floor system, provided the bridge is a through bridge. When the bridge is used as a deck bridge and the floor system laid upon the top chord, there is the same neces- sity for vertical posts. In countries where it is possible to procure good timber of large size, the Warren triangular bridge is as economical and convenient a form of truss as can be built. To use it in its most economical manner the lower chord is usually made of iron, as that simply has to withstand tension ; but the tie-braces are made of wood, and also the top chord. One point which is to be studied carefully in the Warren triangular truss is the fastening of these braces, as they must be fastened in such a manner that they not only will resist compression, but also that they will act as ties and resist tension. This necessitates a rather more complicated method of fastening. Another great advantage connected with the use of the trian- gular truss is the ease with which, when necessary, any piece can be removed and replaced by a new piece without in any way im- peding the passage of trains over the bridge during the operation. In the case of wooden or combination bridges this becomes a matter of great importance, as the timber in these bridges is ex- posed to alternate dryness and moisture, and thus, in a compara- tively short time, decays, and there soon is the necessity of replac- ing the bridge piece by piece ; therefore any bridge that is con- structed in such a manner as to make this possible, without im- peding the traffic on the road, possesses a great advantage over other forms of bridges. The triangular truss is a favorite method of construction on all railroads in the southern part of this coun- try running through that belt where it is possible to obtain, at comparatively slight cost, yellow pine for the requisite timber. We come next to the last type of bridge that has been used, to 474 THE POPULAR SCIENCE MONTHLY. any great extent, upon the railways of this country. This bridge is called the Post bridge (Fig. 24), taking its name from its in- ventor. The characteristic features are that the compression members are inclined at what is claimed to be the most econom- ical angle — that is, the most economical in regard to the amount of strength obtained for the amount of material used. They are POST TRUSS Fig. 24 so inclined as to cross one panel of the bridge, while the tie-rods, running at an angle with the braces, cross two panels. This is the only advantage that can be claimed for this form of truss, and much of this so-called advantage is more than counterbalanced by some of the difficulties encountered in the actual construction ; and whether the bridge really in itself is a more economical bridge than the Pratt, yet remains to be practically proved. We stated in the beginning that bridges consist of arches and suspension bridges as well as framed trusses. The relation be- Fig. 25 BOWSTRING GIRDER. V \ \ \ Fig. 27 \ H \ / A \ \ / T7 \ / / X7 \ \ ^*!__ N \ / \ / / V A / \ / \ \ / \ / / ^ / / \ / / \/ tween the framed truss and the arch will be readily seen by an examination of Fig. 25. Take a truss of the Pratt pattern ; then, in place of having the top chord parallel with the lower chord, let the compression members be increased in length, as shown in the drawing, and the top chord take the form of an arch, and we have the bow-string girder. The ends of the arch on each side are simply held together by means of the lower chord, which acts as a tie-rod upon them. EVOLUTION OF THE MODERN RAILWAY BRIDGE. 475 Now, in the case of a masonry arch (Fig. 26), which has the weight all on top, there is no necessity for the tie-rod to hold the ends of the arch together, for the reason that the ends of the arch are always built so as to abut against heavy masonry which will withstand the horizontal thrust, and thus without the interven- tion of any tie members we have a perfect bridge by means of the arch, all the weight coming upon the top being passed from one stone to the other in the arch until it reaches the two abutments the same as in a framed truss. The suspension bridge (Fig. 28) is nothing more or less than the arch turned upside down. In the arch, as we have seen, the SUSPENSION BRIDGE. Fig. 28 'A X//{ (A ' / » ■\ only strain that comes upon it is compression ; in the suspension bridge, on the other hand, the only strain that comes upon the sustaining member or cable which is stretched between the points of support is tension. In the arch bridge all the weight comes above the arch and presses down upon it ; in the suspension bridge all the weight comes below the suspension chains and simply 476 THE POPULAR SCIENCE MONTHLY. hangs from thera. In the suspension bridge the cables, chains, or any other flexible devices are stretched between the two points of support, the ends carried over the tops of the towers, and firmly anchored in the ground beyond. Then the roadway of the bridge is simply hung by tie-rods from this suspension cable. The suspension bridge is undoubtedly one of the oldest forms in existence. At the time when our ancestors were either swim- ming across creeks, or cutting trees, making them fall across in order that they might walk over on them — that is, one thousand years ago — the Japanese were building suspension bridges which are in use to-day, using iron chains for suspension cables, and in every way building them in as scientific a manner as the East River Bridge in New York is built to-day. Of course, there was a certain crudeness as to the methods which were used, but this in no way affected the scientific principles on which the bridges were built. It is not our purpose, however, in this paper to take up the question of suspension bridges. We pass now to the last form, and in this country at least the latest form, of the framed truss — that is, the cantilever bridge. The object of the cantilever bridge is to make possible the eco- nomical construction of long, clear spans of a rigid truss, and thus do away to a great extent with the necessity of suspension bridges, as there are many disadvantages besides the mere one of expense that are connected with the use of suspension bridges. The other advantages of the cantilever will be taken up later. To show the development of the cantilever bridge, we will take two king-post trusses (Fig. 29) ; putting them together, we form a bridge of two spans, which has an abutment at each end and a pier in the center. In case this was for the passage of a river, the center pier would come directly in the center, obstruct- ing navigation to a great extent, and otherwise prove an incon- venience. We use the king-post truss merely as the most simple form of truss that is built. In any other form that could be built the result would be the same ; that is, for a bridge of two spans there would be a pier in the center of the river, and for any span that could be built of any of the types of bridges which we have noticed thus far the amount of open space that would be left in EVOLUTION OF THE MODERN RAILWAY BRIDGE. 477 the center of the river may be less than that required by naviga- tion, so that, from what we now have, our only remedy would be the use of the suspension bridge. In order to do away with this, and make a wider opening in the center of the river, suppose we take away the center pier and replace it by two piers directly under the king-posts of the truss (Fig. 30). In this way we see we have left a large, clear span in / / & A \ \ \ \ \ \ / \ / \s. \ \ \ \ \ \ \ CANTILEVER. v/4 Fig. 30 the center of the river, and we have in no way increased the amount of materia^ necessary for the building of the bridge, and the two spans that we are using are now balanced, each upon the top of its respective pier. These two spans are fastened together in the center, and the shore ends of both are anchored firmly, in order to keep them from tipping up whenever a load comes upon the river end. We thus see that we have doubled the clear span in the center of the river, and we have what is called a can- tilever bridge ; that is, a truss supported at one end, and extending out over an opening, there being no support under the other end. Now, suppose it was desired to make this center opening still larger, we have simply to move the piers apart (Fig. 31). We / A / / / C/ / \ \ CANTILEVER. \ \ V Fig. 31 / / / B/ / ''/A \EE3SEP \ \ \ \ \D >// have our two cantilever spans. The shore end of each is firmly anchored down, and the two other ends, A B, project simply into space. If we build thus, the two ends, A B, are firmly fixed and can not in any way yield to the load that may come upon them. If we now construct an ordinary framed truss, of either the Howe, Pratt, or any other type, and instead of putting this truss upon two piers or abutments we simply hang it between the two ends of the cantilever spans, A B, which are projecting over the river, the weight of this truss will be sustained by the tie-rods from the king-posts, or in the case of the cantilever that run over the tower and are anchored down upon the other side. We thus see that by increasing very slightly the amount of material used 478 THE POPULAR SCIENCE MONTHLY. in the construction of the "bridge we have an open, clear span in the center three times the width that would be possible with the ordinary framed truss, and we have what is known and has lately become famous as the cantilever bridge. The spans C A and B D are called the cantilever spans, and A B the suspended span. The variations in the cantilever bridge are almost infinite, although the principles in all of them are the same. In the place of using the upright truss, for example, this truss can be turned over, and the ties then become braces, the floor comes upon the •^J^iMxi CANTILEVER. Fig. 32 top, the shore ends being firmly anchored in place, and, the sus- pended span held in place, we have a cantilever of the type that has just been erected across the Hudson at Poughkeepsie (Fig. 32), while the first example given you is the type of cantilever that crosses the St. John River at St. John, New Brunswick (Fig. 31). Then, when a greater length is desired and increased strength, as in the case of the bridge across the Frith of Forth, in Scot- land, we simply combine the two, putting the two king-post trusses base to base, and hanging the suspended truss between (Fig. 33). In that way we have the strongest form for the cantilever bridge, and there is hardly any limit to the length of span that can be made by this method. CANTILEVER. Fig. 33 The advantages gained by the use of the cantilever for long- span bridges are as follow : As a substitute for the suspension bridge it is, up to a certain length of span, less expensive, and it can be given great rigidity and stability which are impossible in the suspension. As a substitute for the ordinary framed truss it has the ad- vantages of not requiring any false works for its erection. In the erection of the ordinary bridge there must be built first a timber frame or staging between the piers to sustain the weight of the EVOLUTION OF THE MODERN RAILWAY BRIDGE. 479 different parts of the bridge while it is being put together. This is a great expense ; and in some cases, where the bridge is far above the water, the current very rapid, or an existing necessity of not obstructing the water-way, becomes impossible. In the erection of a cantilever, each cantilever span is balanced on its own pier and built out each side from the tower in such a manner as to preserve this balance until the shore ends are anchored firmly, after which the river ends can be extended as far as de- sired. The suspended span, which is never of extraordinary length, can usually be built directly from the ends of the can- tilever spans, and the necessity of false work entirely done away with. In all bridges of long span that the weight of the bridge itself is by far the greatest load that the bridge has to bear. In bridges of short spans, the weight of the locomotive and train coming upon them suddenly constitutes the greatest load, as the weight of the train is greater than the weight of the bridge itself ; but as the size of the bridge increases, its weight increases very rapid- ly, and the weight of the locomotive and train becomes almost nothing as compared with the weight of the bridge itself ; that is, if any of these long bridges are built strong enough to hold them- selves up, with a very slight margin of safety above that, there is scarcely any danger of their ever falling from any weight that could come upon them from an outside load. For this reason, in building short-span bridges, the amount of economy that can be exercised in the use of material is very small, as the bridge must be built stiff and rigid, even if this necessitates the using of much more material than the absolute weight of the tender and locomo- tive that come upon it would demand. For this reason plate gird- ers or flanged girders have many advantages connected with their use for short-span bridges, because the whole amount of material used is comparatively of little value, and extreme stiffness and rigidity are the result ; while in the case of long-span bridges, such as cantilever, or any remarkably long bridge, every calculation must be made with the greatest care in order to reduce the amount of necessary material as much as possible, because by reducing the amount of material used the weight is reduced, and that again reduces the amount of material. The factor of safety to be used can be only two or three in long-span bridges, while in short spans it should run up even to ten. Although cantilever bridges are of rather recent use in this country and in Europe, and much has been written claiming them as an invention of modern times, still, the same can be said of them that was said of suspension bridges — that there at present exists in Japan, built by the order of the Mikado two hundred and fifty years ago, as perfect and scientific a cantilever bridge as any that 480 THE POPULAR SCIENCE MONTHLY. are built in this country or in Europe ; and in this way, as in many others, the Japanese show that two or three hundred years ago they had advanced to a wonderful degree in the study of applied mechanics and the " strength and resistance of material." The only trouble is, that they stopped advancing for two or three hundred years, and up to ten or twenty years ago were not as far ahead as two hundred years earlier. In closing, I wish to call your attention for a few moments to some of the differences that exist between the American and English practice of bridge-building, and the causes that have led to these differences. The characteristic difference is in the meth- ods used in joining together the different parts of the bridge. American bridges, as a class, are pin-connected — that is, the different members, when possible, are joined by means of a steel pin passing through holes in the ends of the pieces. These joints are perfectly flexible, and each member is designed to do its own particular work. English bridges, as a class, have " riveted con- nections"— that is, the members are fastened rigidly together, and each member is designed to act simply as a part of a rigid, inflexible whole. The causes that have led to this difference are as follow : In the construction of bridges the English engineer started with the flanged girder of cast or rolled iron, or some other form of a stiff beam, and as the bridges increased in size so as to necessitate the framing of a truss, his whole effort was directed toward mak- ing that truss as nearly similar to the original flanged or box gird- er as possible. This led to perfect rigidity at the joints. The American engineer, on the other hand, had very little or no iron and steel to work with, and of necessity used wood. As the necessary bridges were of considerable span, the only possible solution of the problem was the pinning together of small pieces of wood so as to form a connected series of triangles. The joints in wood could not easily have been made rigid, and it was not de- sirable that they should be, as the strength of wood is very slight when the strain is applied in any direction other than in the direction of the fibers of the piece, and the use of the pin joint, theoretically at least, insures this line of action. There has been much ingenuity displayed by our engineers, in the years gone by, in the combinations of triangles used in bridge-designing, and in many cases this has led to absurdities. The whole tendency, how- ever, at present in American practice is to extend the use of riv- eted joints, and in English practice to extend the use of the " pin connections." Both are working in opposite directions, but from opposite sides, and therefore toward the same point. One great drawback to the more general use of pin connec- tions by English engineers is the immense first cost of the plant AGRICULTURE AND THE SINGLE TAX. 481 necessary to do the work. Our bridges are -usually designed and built by the same company, so that the design within certain lim- its corresponds to the available plant of the manufacturer, and the expensive tools can be used over and over again. In English practice, however, the bridges are designed according to the ideas of the individual engineer, and then some firm has to build them in all their details to correspond with the design. If the construc- tion necessitates expensive machinery and tools, no company would undertake them at any reasonable cost, as there would be very little chance of any other similar design being offered upon which they could use the same tools. In riveted work, however, the tools required are within certain limits the same, regardless of the details of design. Pin-connected bridges are much more economical for large work than riveted ones ; and this fact, taken in connection with the unrivaled facili- ties we have for doing the work, accounts for the fact that in the building of large bridges American firms can underbid any others, and not in any way lower the character of the work done.* ■»♦» AGRICULTURE AND THE SINGLE TAX. Br HOKACE WHITE. I. |~N the second half of the eighteenth century there arose a school -L of thinkers in France to whom, at a later period, J. B. Say gave the name of physiocrats. The founder of the school was Frangois Quesnay. Turgot was one of his disciples, and was the most distinguished member of the group. De Gournay, the elder Mirabeau, Morellet, and Dupont de Nemours are well-remem- bered names of the physiocratic school. Adam Smith was in Paris in the year 1764, and was much in the society of Quesnay and his friends. The exchange of thoughts among these great men must have been mutually beneficial, but the question that has since been raised and discussed with some heat, whether the author of the " Wealth of Nations " gained more from that inter- course than he gave in return, is a barren controversy. At that time governmental interference with the business and livelihood of the people was incessant and almost universal, and * Lattice riveted bridges and double intersection trusses have not been discussed, as their introduction would only have obscured the object of the paper. In regard to the advantages of the American pin-connected bridges for long spans, we may say that from the most recent data the time required for the erection of the bridge, after everything is ready, is only about one twentieth of that required for the erection of the English riveted bridges. VOL. XXXVI. — 31 482 THE POPULAR SCIENCE MONTHLY. was generally acquiesced in. The doctrine that money was the only form of wealth was held by nearly all statesmen and trad- ers, and had resulted in the establishment of the so-called mer- cantile system. The physiocrats taught the contrary of both these conceptions. They held that governmental interference with the gainful occupations of the people was bad for both government and people, since it hindered the increase of wealth and the productiveness of taxes. They maintained that money was not wealth except in a secondary sense, as a tool and instru- ment of exchange, since all persons who acquire money find it for their advantage immediately to lay it out for other things. These two contentions of the physiocrats constitute their claim to the admiration of mankind. They had another doctrine by which, as it has turned out, they are now more generally distinguished. They held that land was the only source of wealth, and that all occupations except agriculture were unproductive. Agriculture, they said, yielded a "net product" over and above the wages of the cultivator during the time he was en- gaged in producing the crop. This net product went to the landlord, and might rightfully be taken by the Government to the extent necessary to defray the public expenses. They accord- ingly proposed and advocated the impot unique, or single tax, on the income derived from landed property. The residue of the net product remaining in the landlord's hands after the payment of taxes was, in their judgment, the annual and sole increment of the world's capital and stock in trade for the upbuilding of civilization. All other trades, such as manufacturing and commerce, were sterile. These served as the clerks, the agents, the porters of agriculture. If any of these saved anything from their earnings as the handmaids of agriculture, competition would cut down their gains, so that eventually they would have nothing left over at the end of the year. Adam Smith agreed with the physiocrats in their views re- specting governmental interference with private business, and as to the true character and functions of money. He differed from them as to the " net product." He held that land was not the sole source of wealth, but that all useful labor was to be reckoned, equally with agriculture, among the sources. His answer to the physiocrats is embraced in Chapter IX, Book IV, of the " Wealth of Nations." Notwithstanding an occasional subsequent flicker, it may be said, speaking broadly, that if there ever was any economic conclusion upon which the world had agreed it was that the physiocratic docrine of net product and single tax was erroneous. AGRICULTURE AND THE SINGLE TAX. 483 II. This consensus of opinion held good for something more than a century. In the year 1879 Mr. Henry George published his "Progress and Poverty," in which he revived the single-tax idea with some variations. Mr. George says that he arrived at his conclusions by independent reasoning, without knowing any- thing of Quesnay or his doctrines (" Progress and Poverty," p. 381). The only practical difference between Mr. George and the physiocrats is that he would take all the "net product" for public use, while they would take only so much as might be re- quired for the purposes of economical government. There are differences of reasoning between them, but this is the only differ- ence in results.* Mr. George's latest commentator, Mr. Samuel B. Clarke,f allows that the net product may turn out to be a net deficiency as regards the full support of government. In one of his opening paragraphs he says : " He (George) assumes, without conclusive evidence, that economic rent in the present state of this and every civilized country largely exceeds the amount required for necessary gov- ernmental expenses. The assumption, however, is not essential to his scheme. If the amount realized by the proposed tax would not support the Government, of course there would have to be taxes on other things ; but the amount to be raised would be less by the amount of the land-value tax." If we could settle this question of the sufficiency of economic rent to sustain all the costs of government in advance of actual experiment, much would depend upon what we should call neces- sary governmental expenditures ; much would depend also upon what we should take for the basis of economic rent. The lat- ter is defined by Mr. Clarke as "the fair rental value of land exclusive of distinguishable betterments." Buildings, fences, and growing orchards are distinguishable betterments. Perhaps roads and ditches made at the sole expense of the land-owners may be so considered. But are clearing, grubbing, breaking, marling, grading, and like ameliorations distinguishable ? If so, * In the " Forum," September, 1889, Mr. Thomas G. Shearman, one of the most dis- tinguished members of the single-tax party, holds that it is not necessary to push the single tax beyond necessary governmental expenses. The absorption of the entire ground-rent, he says, " is not a practical question at present, and will not be for a long time to come, if every This marks the recent divergence between Mr. George and the " Standard " on the one hand, and the Rev. Mr. Pentecost and the " Twentieth Century" on the other. With the latter the single tax is a cult ; with the former it is now only an economic doctrine, or at most a " pious opinion." But certainly " Progress and Poverty " teaches a cult, if it teaches anything. f " Current Objections to the Exaction of Economic Rent by Taxation considered," by Samuel B. Clarke, of New York ; pamphlet edition, 1889. 484 THE POPULAR SCIENCE MONTHLY. we have Henry C. Carey's word for it that no farming district or county or township will sell to-day for as much as it has cost to bring it to its present state of productiveness. I do not agree with Mr. Carey in this. I only mention it to show what a chasm of divergence will open whenever the Government shall under- take to define distinguishable betterments and separate them from undistinguishable ones for the purpose of securing what Mr. Clarke calls " a firm foothold " for the inscribing of the fair rental value of each piece of land in the public accounts. Still, this difficulty may not be insuperable. I propose to examine Mr. Clarke's pamphlet rather than Mr. George's book, because the former, although drawn almost wholly from the latter, embraces in small compass and with eminent fairness all that is needed to set out the single-tax argument, and does not lure us into by-ways as Mr. George often does. " Why should land be singled out, and its holder made to bear a burden from which the owners of other sorts of property are exempt ? " This question is answered by Mr. Clarke, first on economical and then on ethical grounds. On economical grounds : " Because (1) material progress in a community where absolute private prop- erty in land is maintained by law, acts, by force of that fact, like a wedge thrust midway into the social structure, to raise a few without effort or merit on their part, and to grind down the masses of men, however meritorious they may be ; and because (2) property in land being qualified in the way proposed, poverty will be abolished for that increasing class in civilized commu- nities who are willing to work, but have few opportunities to do so advantageously." We are not authorized to infer from this statement that in a community where absolute private property in land is maintained by law, e. g., the United States, " a few " belonging to the landless class never get unduly elevated, or that land - owners never get ground down, in both cases regardless of merits, or out of all pro- portion to merits ; nor can we infer that in a community where the state is the landlord, e. g., British India,* a few are never ele- vated and the masses never ground down, regardless of their mer- its respectively. But we may fairly demand that the writer shall point out his "few" before he asks us to accept his statement. Do land-owners in the United States get rich faster than other people ? To say that the Astors are very wealthy, and that they * De Laveleye, in his work on " Primitive Property," gives the reason for holding that the state is the real landlord in India. "Where the land-tax rises so high," he says, "as to absorb nearly the whole produce and to leave the cultivators only the bare means of sub- sistence, it is obviously an actual rent that is paid ; and if it is the state that receives such a tax, it may be considered as the true proprietor." AGRICULTURE AND THE SINGLE TAX. 485 have their counterparts as land-owners in all our lesser cities, does not answer the question, because the Vanderbilts, the Havemeyers, the Drexels, the Rockefellers, the Carnegies, the Armours, and the Pullmans are also very rich, and they do not own land to any large extent. Can anybody point to a similar group of rich men whose income is derived from agricultural land ? Any man of fair intelligence can answer the question for him- self. The opportunity has been open to me, for example, to get rich by land-owning ever since I arrived at man's estate. It has been open to me to acquire land at all prices, from nothing per acre up- ward. I was once domiciled for a short time at a place where land was obtainable at the former price — good arable land, underlaid by a workable vein of coal. I filed an entry on one hundred and sixty acres of it at the United States Land-Office at Lecompton, Kansas ; but, happening to receive an offer of twenty-five dollars X^er week to work on a newspaper shortly afterward, I abandoned my claim, and I am sure that I made no mistake in the point of view of dollars and cents. I took up my abode in the city of Chi- cago when there were only sixty thousand inhabitants there. The growth of that place has been, since that time, one of the remark- able phenomena in the world's history, and a great part of this growth took place under my eye ; yet I have never seen the time when I thought I could make better use of my small capital by becoming a land-owner than by following other pursuits. But I have had some experience as a land-owner. The land that I have at one time and another owned, whether urban, suburban, or agri- cultural, or taken altogether, has not served me as well on the whole as other investments. I make this personal reference because I know that my expe- rience tallies with that of many others. Mr. Henry George, for example, has fairly earned all that he possesses of this world's goods. I venture to ask whether the same amount of labor, dili- gence, and foresight that he has bestowed upon his own vocation of book-writer, journalist, and publisher, if applied to the acqui- sition and use of land, would have netted him as much. Undoubt- edly both he and I, by the use of hind-sight, can see where we might have made larger gains by becoming land-owners than we have ever made. But so, too, by the use of hind-sight we can see how we might have made as much or more in still other ways. We might have invented a telephone, for example. Before proceeding it should be noted that Mr. Clarke expressly repudiates the idea that the single-tax argument rests upon the idea of an " unearned increment." The rise in land values due to the growth of population has nothing to do with it, or at most only serves to set it in a more glaring light. " The argument for the land-value tax " (he says) " is very apt 486 THE POPULAR SCIENCE MONTHLY. to assume the form, and, if we may judge from current criticism, is quite generally understood to have the form, that because the value of land increases without effort on the part of the land- holders as the community grows, therefore the community has earned such value, and may justly take it for common purposes. In that form the argument is fallacious beyond question." Land, he shows, is subject to decrease as well as to increase of value, and other kinds of property increase or decrease in value quite independently of the owner's exertions, merits, or demerits. The second economical reason why land should be singled out and its holder made to bear a burden from which the owners of other sorts of property are exempt, as stated in the quoted para- graph, is " because property in land being qualified in the way proposed, poverty will be abolished," etc. No mode or process by which poverty is to be abolished being furnished, we are at liberty to infer that, if a marked addition were made to the land-tax all over the country, the poor would soon find themselves in easier circumstances ; and that if successive additions were made, they would become more and more prosperous ; and that when the whole rental value had been taken, there would be no poor people anywhere. Now, taxes on land are paid by land-owners (I believe that Mr. George agrees to this). The proposition then is, that if land- owners were required to pay into the public treasury as much as they could by any possibility pay, other people would be so much benefited that even the poorest people in the world would be in comfortable circumstances. The only way that this great change can be brought about is by the abolishment of all other taxes. I do not undervalue the relief that would accrue to industry from the abolition of indirect taxes. I hold that it should be the first step toward the elevation of the poor man, and the bettering of his condition, to let him have and enjoy what he earns — all of it, except just sufficient to keep him watchful of tax-eaters and tax-thieves. But suppose that Divine Providence should bestow upon us rulers who could carry on government without any taxes what- ever. "Would that dispensation abolish poverty ? Those who think so are bound to tell us how. The single-tax philosophy does not propose to constitute a fund for general distribution. If anything should be left over after defraying all necessary expenses of government, the residue is to be applied to the common benefit and delectation through free libraries, music halls, picture galleries, higher education, etc. There is to be no alms-giving, because there are to be no poor. I take it that the utmost good to be derived from the exemption of all others than land-owners from taxation would be gained equally AGRICULTURE AND THE SINGLE TAX. 487 by any device or dispensation which should enable government to be carried on without taxes. I protest against the assumption that this would abolish poverty, unless those who hold that it would shall offer us something more conclusive than their private opinions. III. The ethical reason why land should be singled out exclusively for purposes of taxation is based upon what are called " natural rights/' I quote Mr. Clarke's words : " The second answer, in substance, is : Because land is not rightfully the subject of absolute property, and because the injus- tice of allowing it to be so acquired and held will be remedied by the exaction and application to common uses of economic rent. " The standard of right, to which this answer appeals, is that conception of inherent or underlying rights which is usually de- scribed, perhaps not altogether happily, by the phrase natural rights." General Francis A. Walker, in his "Land and its Rent," dis- poses of the dogma of natural rights as applied by Mr. George with a few words of sarcasm, which, really do embrace the true philosophy of the subject. He says that as he has never lived in the state of nature himself, but has passed his whole life in com- munities more or less civilized, he does not feel moved to discuss the subject on any other than economic grounds. According to my observation, more people of fair intelligence are taken in the single-tax net by this dogma than by all others together ; and even when they are shaken from every other, they still cling to this as a sheet-anchor. It is worth while, therefore, and indeed necessary, to give some particular attention to it, in an elementary way. Having cautioned us against the use of the phrase " natural rights " as not altogether happy, Mr. Clarke proceeds to use it twenty-one times in the next twenty pages, as though it were as happy as possible, assuming in all cases that every person born into the world has a natural right to land and a natural right to the best land — conditioned, however, upon every other person's equal right to the same land. The only way to make these con- flicting natural rights effective is to confiscate economic rent through the taxing power. What are "natural rights" ? Let us test them for a moment by the Socratic dialogue, the interlocutors being A and B : A. When you speak of natural rights, you mean rights accord- ing to nature, I suppose ? B. Undoubtedly. A. And that the origin of such rights is traceable to the state of nature ? B. Certainly. 488 THE POPULAR SCIENCE MONTHLY. A.

Then the opposite of natural rights would be artificial, con- ventional, and legal rights ? B. Not the opposite exactly, but the counterpart and supple- ment of such rights. A. But as to their origin only, you would say that the two origins were opposite to each other, the one being according to nature and the other not according to nature ? B. Yes, that would be a fair statement. A. How do we learn whether anything is according to nature, so as to distinguish it from things not according to nature ? B. By observing what takes place in a state of nature. A. So, if we saw a wolf devouring a sheep in a forest, we should say that it was the nature of wolves to kill sheep ? B. Of course. A. But if we saw a dog guarding a flock of sheep and driving them into a sheep-fold at night, should we say that it was the nature of wolves to kill sheep, but the nature of dogs to protect them? B. No, we should say that the dog had been trained to take care of sheep, although his ancestors had themselves been sheep- killers. A. "Why should we say this ? B. Because we know it by observation and testimony. A. Do observation and testimony teach us that in a state of nature all men have equal rights ? B. We do not know exactly what is the state of nature appli- cable to man, since he has improvable faculties and is always changing, or is susceptible of change. A. Yet the hypothesis is that equal rights are according to nature — that is, to man's nature. Are we to say that natural rights exist because there is no state of nature for man, as there is for dogs and wolves ? B. Although man has improvable faculties and is susceptible of change, and although his actual state of nature is hidden from us in the darkness of ages, before written language existed, yet if is possible to approximate toward the state of nature by observing what takes place among those tribes that are nearest to the state of nature. A. And do we observe that among such tribes equal rights exist as to life or liberty, or any kind of property ? The colloquy would " naturally " come to an end at this point, because, in a state of nature, might makes right. The natural man takes what he wants, wherever he can find it. He takes the AGRICULTURE AND THE SINGLE TAX. 489 weaker man's wife or property, and kills or enslaves him, as the ease may be.* It is safe to say that this has been the state of man in all countries " ere human statute purged the gentle weal." The village community, in which the land was held in common for the villagers (not for everybody), was the outgrowth of law, of art, of convention; but even this was subject to the law of the strongest, in the sense that every village community was liable to be dispossessed by any wandering tribe better armed, or more numerous or braver, that might suddenly emerge from the neigh- boring forest or mountain. The feudal system displaced the village community because the village could not protect itself against armed robbers, f The recent searching examination of " natural rights " by Prof. Sumner \ renders it unnecessary for me to go more deeply into this branch of the subject. What are commonly and loosely called natural rights are the outcome of centuries of hard knocks, the results of training, education, and experience, the very flower and last refinement of art as applied to society and government. Mr. Clarke cites certain decisions of the Supreme Court to show that natural rights have " their seat in the bosom of God and their voice in the harmony of the world," to quote from Hooker's defi- nition of law. But all such opinions are obiter to this discussion. That our ideas of natural rights, civilized though we be, change greatly in the progress of time, is proved by our own recent his- tory, the right to liberty having been denied by a majority of Americans within our time. Conjoined to the doctrine of natural rights, though not a neces- sary part of it, is the doctrine of equal rights, which I share as fully as anybody. But, if I attempt to draw generalizations from it, I am confronted by the fact that it is not universally held, but is really confined to a small portion of the human family. The * The movement now in progress for the suppression of the African slave trade has shed an abundance of light (if any more were needed) on the subject of " rights " as they actu- ally exist in the state of nature. The prime difficulty there is not Arab slave-dealing, but the practice prevailing among the native tribesmen of enslaving each other for the pur- poses of human sacrifice in their religious ceremonial. Arab slave-dealing is not the cause of African slavery, but merely an adjunct to it. f " Not to be killed," says Stendhal, " and to have a good sheepskin coat in winter, was, for many people in the tenth century, the height of felicity " ; let us add, for a woman, that of not being violated by a whole band. When we clearly represent to ourselves the con- dition of humanity in those days, we can comprehend how men readily accepted the most obnoxious of feudal rights, even that of the droit du seigneur. The risks to which they were daily subject were even worse. The proof of it is that the people flocked to the feudal structure as soon as it was completed. In Normandy, for instance, when Rollo had divided off the lands with a line, and hung the robbers, the inhabitants of the neighbor- ing provinces rushed in to establish themselves. The slightest security sufficed to repopu- late a country. (Taine's "Ancient Regime.") X " Popular Science Monthly," July, 1889. 49o THE POPULAR SCIENCE MONTHLY. Hindus, for example, hold tliat rights ought to be apportioned according to caste. In the Mohammedan world the doctrine of fate completely overtops and stifles the doctrine of equal rights. A considerable portion of the human race hold that women have no rights. A majority of the civilized races hold that woman's rights are inferior to man's rights, and we ourselves do not con- sider them embraced in the term "popular sovereignty." Yet they are one half of the human race, and the more meritorious half.* I shall assume, without further argument, that the rights of life, liberty, and property, including land, all rest upon experience, translated, after infinite trouble, conflict, and bloodshed, into law, and this notwithstanding any opinions of the Supreme Court that can be quoted to the contrary. A title to anything, land or personal property, is defined to be "a just cause of exclusive ownership," and a title-deed is the accepted evidence of the same. The law tells us what shall con- stitute just cause of exclusive ownership and what shall constitute good evidence of it. It is the same law, as to its origin, that fixes, prescribes, defines, and enforces all rights. The law has prescribed in this country the following among other things : (1) That human life shall not be taken except in self-defense or by due process of law ; (2) that private property shall not be taken for public use without just compensation ; (3) that slavery or involuntary servitude shall not exist except as a punishment for crime — this is placed last because it was enacted last. On the ground of salus populi suprema lex the state holds com- mand over the lives and fortunes of its citizens, and to this sover- eignty land forms no exception. The state may draft the citizen into its army or navy, and send him into battle where he may be killed. It may likewise take his landed property or his personal property. It is the sole judge of the occasions and the reasons. But it must act in accordance with its own constitution. It must not arbitrarily choose A, B, and C to go to the wars. It must not take private property without just compensation. If it does these things, it subverts itself and plunges into chaos. There is no peculiar sacredness about land titles as distin- guished from other titles. If the annual tax on land is not paid, * Jeremy Bentham has given an analysis of the phrases in common use which are synonymous with law of nature, such as moral sense, common sense, law of reason, natural justice, natural equity, and fitness of things. " Common sense," he says, " means a sense of some kind or another which the author affirms is possessed by all mankind ; tbe sense of those whose sense is not the same as his being struck out of the account as not worth taking. ... If such a man," he adds, " happens to possess the advantages of style, his book may do a considerable deal of mischief before the nothingness of it is understood." ("Principles of Morals and Legislation," chap, ii.) AGRICULTURE AND THE SINGLE TAX. 491 the title is subverted at once. So, too, if a special assessment, or a mere water rate, is not paid, the land is sold, and a new title deliv- ered to the purchaser, and this happens even if the non-payment is the result of accident. Personal property is liable to seizure and sale in like manner, and this is right, because the state must have the means of existence. All persons have had notice that such are the conditions of civilized life, the alternative to which is the feudal system, or the worse condition that went before it. When we are told that the state could not divest itself of the right to resume possession of the land, we reply that it never has done so. It has only divested itself of the right to take it with- out just compensation. If any casuist puts himself back of the contract, and says it was wrong in the beginning and void db initio, he has before him the immense task of turning the world over without a fulcrum ; for the world, after an incalculable deal of shifting and balancing, has settled down to the belief that agree- ments made in writing should be kept. Suppose we admit that there are two sides to the question, and that it is submitted to a jury from the moon. A holds that pri- vate property in land is a disadvantage to society, and should therefore be abolished without compensation to owners. B holds that it is an advantage to society, independently of constitutions and laws, and he shows in addition that a solemn agreement has been made that it shall not be abolished without compensation. Both advance such arguments as they may. A says (using the words of Mr. George in his speech at Brighton Beach, July 28, 1889) : " So monstrous is private ownership of land, so unjust is it — so ridiculous even is it, that a few men should be the owners of the element on which and from which a whole people must live — so clear is it that all men have by nature equal rights to the use of the land — that private property in land as we know it can only long continue where from the force of habit it is acquiesced in and never questioned. When it is thought about, when it is talked about, even when it is defended, it is doomed." B replies that " force of habit " is another name for human ex- perience, and that it has stronger presumptions in its favor than anybody's inner consciousness ; that the usefulness of land resides in its cultivation, and that no man can show from inner con- sciousness that better, or as good, cultivation would result from the abolition of private ownership ; and that, if worse cultivation should follow, the whole human race would be sufferers. Would not the men from the moon say : " Gentlemen, your arguments are somewhat confusing. We perceive that private ownership of land, like most of your institutions, has advantages and disad- vantages ; but there is one fact about which no confusion exists, 492 THE POPULAR SCIENCE MONTHLY. and that is, that men ought to live up to their agreements. "We accordingly give our verdict to B. And we do this with the more confidence because we believe that, when the disadvantages be- come clearly preponderant, you will find a way to overcome them without shocking the moral sense of distant observers." IV. Are the taxes on land in this country high enough or not ? Is economic rent sufficient in amount to support government ? We will consider these questions in their relation to agriculture. The generally received idea of the single-tax party is that held by the physiocrats, that all wealth proceeds from agriculture, using that term to include all the products of the earth and the sea. This is a corollary of Mr. George's book, although I believe he has not explicitly affirmed it. I find an apt statement of it in the " Twentieth Century" of August 3d, viz. : " Where all land is occupied, the annual rental value of the land of a nation is, theoretically, equivalent to its net annual pro- duction— that is, to the total production, less sustenance, interest, and replacement. This, through private land-ownership, is now all absorbed by a small number of individuals." * It is needless to say that mere space, which is not applied to the growing or gathering or mining of anything, is not to be in- cluded in the wealth-producing parts of the earth's surface, ac- cording to the physiocratic conception — such as lots in towns and cities. If all wealth comes from the earth by means of agricult- ure, mining, hunting, and fishing, why should not they pay all the expenses of government and a fund besides for the general use ? Would not those industries, after such deductions, still be as well off as the industries which have no share in the land ? Is not the whole of a thing equal to all of its parts ? It is true that man draws his sustenance from the earth, and that the annual surplus which takes the form of capital, of what- ever sort, there has its start. But where does agriculture begin and end ? It is commonly supposed to begin with the making of roads, the clearing of land, and the destruction of beasts of prey. But, before land can be cleared, tools must be made. Axes, plows, spades, wagons, bows and arrows, gunpowder perhaps, must be manufactured. And where does it end ? All production is under- taken to satisfy man's wants. These are not satisfied when a bale of cotton has been picked or a ton of wheat gathered into a barn. The wheat must be ground into flour, the flour must be baked * I do not find any explanation of the word " theoretically," but I suppose that it wa3 not used without a purpose. Theoretically a man who owns the only coal mine on the line of a railroad has a valuable monopoly, but it may turn out practically that he only has the privilege of working it on terms fixed by the railroad. I can point to cases of this kind. AGRICULTURE AND THE SINGLE TAX. 493 into bread, the bread must be carried to the consumer. All these processes require labor in countless forms in the production of machinery, buildings, tools, packages, and transportation. The bale of cotton must be packed, carried to and fro, spun, woven, and again carried to and fro. So of every product of the earth, without exception. All industry and all commerce are concerned in changing the forms and places of the products of agriculture, forestry, mines, and fisheries. John Stuart Mill (" Political Economy," Book I, Chapter II) asks why the grinding of corn should be considered a manufact- uring employment, while the thrashing of it is agricultural. The only reason, he says, is that thrashing is usually done on the farm, while the grinding is done at a mill. Butter-making is counted an agricultural employment if it is done on the farm, but a manu- facturing employment if it is done at a creamery. But it is the making of the butter, and not the place of making, that is the essential thing. * Carry your imagination along all the ramifica- tions of human industry to its farthest confines, and where can you find anything that is not analogous to the two related em- ployments of the milk-maid and the butter-maker ? Mr. Mill shows that the labor of astronomers, who help the sailor to find his way by the shortest paths over seas, carrying the farmer's products, is productive labor, and that whether it be called agri- cultural or not is of no importance to the sum total of the world's wealth. To draw a distinction, therefore, between agriculture and the manipulation and transportation of its products, as a source of wealth and taxes, is false reasoning. Taxes must be apportioned among political units. The State of Connecticut is one such unit, and I choose this for present con- sideration because there has been a recent official examination of the profits of agriculture in that State, which enables us to see what economic rent amounts to in one of the most industrious and prosperous communities in the Union. It is embraced in the " Report of the Bureau of Labor Statistics for the year 1889." Mr. Hotchkiss, the commissioner, has sought to make out as good a case for agriculture as possible, to show that it is not in a dis- tressed condition, or not necessarily so. What is the showing of economic rent in Connecticut ? Six hundred and ninety-three farms were visited. Three hundred and fourteen report average profits of I3G2.88. Three hundred and seventy-eight report an average loss of $268.59. One reports neither loss nor gain. In this calculation the farm- er's family support was reckoned as part of the farm expenses, which Mr. Hotchkiss thinks is improper, since, in reckoning the gains of other trades, it is customary to deal only with the profits and losses of the business by itself. Making this correction, he 494 THE POPULAR SCIENCE MONTHLY. finds that six hundred and fifty farms make an average profit of $551.36, and that forty-two sustain an average loss of $232.45. The average size of the farms reported on was one hundred and ten acres. I can not agree with Mr. Hotchkiss that the family expenses ought to be deducted in estimating the profits, unless an allow- ance is made on the other side of the ledger for wages of the family. The children of farmers begin to work as early as ten or twelve years of age. Therefore, the first cited computation of the profits of farming in Connecticut is the nearer to the truth. The footings, as summarized by the commissioner, are as follows : Total receipts from six hundred and ninety-three farms $707,153 Total expenses, including family support 690,990 Total profit $16,163 Among the farm expenses we find the gross sum of $37,526 set down to taxes and insurance, but there is no separation of the taxes from the insurance. It is apparent that if the gross sum of $16,163 had been added to the tax bills of these farmers, it would have taken not only the whole of the economic rent, but the profits on their capital besides. The statistics in hand lead me to believe that the single-tax theory is already in operation in rural Connecticut, "unbeknownst" to its advocates — that is, that economic rent is wholly taken by the tax-gatherer from agricultural land plus something from the returns of the farmers' capital invested in live stock, implements, and " distinguishable betterments," which the theory requires us to exclude from the list of taxables. Live stock, farming utensils, and wagons are shown in the report to be sixteen per cent of the farmer's capital, the real estate being eighty-four per cent. But the real estate includes buildings of every description, fences, drains, wells, and every kind of improvement. If this is the true state of the case in one of the most densely populated States of the Union, where shall we look for the revenue that is to liberate all other industry from taxation and abolish poverty throughout the land ? I know something about farming in the West, some years of my life having been spent on a farm in a then frontier State, where the conditions were substantially the same as those now prevailing in Dakota and Nebraska. I know that my step-father, the owner of the hundred and sixty acres under cultivation, had hard work to make ends meet in a very economical way, although he had a family of willing help- ers. Tea and coffee were luxuries never seen in the household. Only one hired man was ever employed on the place, except in harvest-time. Thus the wages bill was kept down to a minimum. AGRICULTURE AND THE SINGLE TAX. 495 The yearly tax bill took tlie whole of the economic rent, if not more, just as it now does in Connecticut. I remember that my step-father was glad to resign his advantages as a land-owner and accept a salary of five hundred dollars per year in a town, in lieu of his chances of being lifted into affluence by " the wedge thrust midway into the social structure," which Mr. Clarke pictures for us. I suspect that Mr. Clarke never worked on a frontier farm. Between the extreme West and the extreme East I presume that instances of economic rent can be found in farming districts, but my observation teaches me that it is an insignificant affair in the total economy of the nation. When you have swept off all buildings and other distinguishable betterments, all live stock and other personal property, and when you have deducted fair wages, or if you please the family support of the farmer (gen- erally of a very meager sort), the residuum of economic rent, I am very sure, will not be worth the trouble of confiscation. If the single-tax theory prevails, what shall be done in those cases where economic rent is a minus quantity ? According to the Connecticut report, three hundred and seventy-eight farms out of six hundred and ninety-three (fifty-four per cent) report no profits, but losses instead. Should they not be compensated in some way ? Would it be fair for the state to take only the choice cuts of economic rent, and leave the bone and gristle ? The least that it could do would be to abolish taxes on all land that yields no return to an industrious cultivator. Of course, there are good farmers and bad farmers. Some can make a liv- ing where others can not. But when the Government, in addition to all its other duties, takes up the task of separating all the dis- tinguishable betterments of the country from all the land in the country, and rack-renting the land afterward, it will probably stop short of the task of discriminating between good farmers and poor ones. It would be obliged to stop taxing the non-profit- making farmers, if indeed it did not consider them entitled to some compensation out of the treasury for their labor. I do not see how otherwise the single tax would abolish the poverty of these three hundred and seventy-eight Connecticut farmers. V. The solidarity and interdependence of useful industry dispose of the complaint that all except land-owners are crippled and cur- tailed of their chance of earning a living. Says Mr. Clarke : "A material thing is not rightfully the subject of absolute property if the appropriation of it by the exertion of one man's natural powers interferes with the equal right of other men to exert their natural powers. 496 THE POPULAR SCIENCE MONTHLY. " The appropriation of land does so interfere. To test the prin- ciple, it will be proper to take for illustration a community like New York or Massachusetts, whose laws maintain private prop- erty in land, and in which all the land has been fenced in or sub- stantially so ; for such communities are numerous, and, as popu- lation increases, will become more numerous. In such a com- munity, obviously, a landless man can not do anything individ- ually. He can not obtain for himself food or clothing or shelter or fire ; he is dependent upon other men for such alms or for such employment as they are willing to give him." When the fight against the English corn laws was in progress, it was urged by the protectionists that agriculture was the most meritorious of all employments, because it furnished food, without which man could not exist. I recall the apt reply of General Per- ronet Thompson, who said that, if you were to throw two men into the street, one without any products of agriculture and the other without any products of manufacture, there would not be much to choose between them. One of them would be hungry and the other naked. But the naked man would very soon be as hungry as the other, because he would have no tools to cultivate the land with, and if the temperature happened to be at zero the naked man would be frozen to death before the hungry man would be starved to death. Mr. Clarke, I believe, makes his living by the practice of law, and, being a landless man, " can not do anything individually." He is " dependent upon other men for such alms or such employment as they are willing to give him." I, too, am in this plight. We two are therefore worse off theoretically than any of the Connecti- cut farmers whose pecuniary condition has been ascertained for us in the report of the Bureau of Labor Statistics. I say " theoret- ically," but I suppose that actually the case is somewhat different. If we are dependent on farmers for food, they are dependent on us for law and newspapers. They might get on after a fashion with- out law and without newspapers, perhaps, but they could not get on without houses, clothing, tools, wagons, railroads, ships, medi- cines, etc., the producers of which in turn have need of law and newspapers. The only man who can do anything " individually " is Robinson Crusoe. Neither of us would care to swap places with him. There are other economic formulas in the essay before us as unsubstantial as this, but space serves to notice only one more. The merit or demerit of this belongs to Mr. George, Mr. Clarke having merely condensed what Mr. George has set forth at greater length. It relates to land held for speculative purposes, and the argument is, that the single tax will wipe out this speculative element and thus benefit society. Thus, it is said : " A very great AGRICULTURE AND THE SINGLE TAX. 497 body of land would become substantially free, and all the people of this country would stand, so far as abundance of natural oppor- tunities are concerned, where their predecessors stood sixty or eighty years ago. . . . Furthermore, the annihilation of the spec- ulative element of value is likely to have a particular beneficial •effect in and near large cities, where now the density of population presents a great and terrible and threatening problem, before which, hitherto, all the wisest and most humane of men have stood gasping and helpless." Capitalists, it is contended, would hasten to erect comfortable houses for rent on vacant city and .suburban lots " if, from the value of such lots, the speculative element were excluded. Houses would compete for men, instead of men cutting each other's throats, as now, in the competition for houses." The first result of the application of the single-tax principle would be to discharge from taxation all unoccupied land in both city and country. The value, or rent-yielding quality, having been seized by the state, nobody would be so foolish as to pay taxes on property which neither now nor hereafter could bring him any return. All such holdings would be abandoned to the state, and this is exactly what is intended. Of course, the state would not tax its own property. Then the state would say to capitalists, " You can build on this land on condition of paying ground-rent, and you will receive such interest on your capital invested in bricks and mortar as the law of competition will allow." But that is what capitalists can •do now. By paying ground-rent they can build as much as they please. How is building to be expedited by changing the land- lord ? In fact, it would be retarded. At present the land-owner is spurred on to improvement by the hope of gaining a ground- rent and by the imposition of a yearly tax on his property, which he must pay whether it yields any return or not. Both these in- centives would be wanting if the land were owned by the state. How would it be with agricultural land held for speculative purposes ? The state would say to the would-be farmer, " You can cultivate this land by paying the rent which neighboring land pays." But can not the farmer get the same land now on the same terms ? Show me the owner of unfilled agricultural land who refuses to allow his acres to be cultivated at a fair rental. I can show plenty of such land within one hundred miles of New York, and all over New England, which any cultivator can have the use of, without paying any rent at all, on condition of culti- vating it. Surely the state would not offer land on more favor- able terms. It would not let the land, rent free, and furnish the capital to cultivate it also. In short, no new opportunities for the cultivation of land would exist unless the state should offer better vol. xxxvr. — 32 498 THE POPULAR SCIENCE MONTHLY. terms than present owners offer. But this the state could not do without sacrificing the fundamental principle of the single tax, which is that the occupier shall pay the full economic rent. It is the testimony of all observers that, of two men of equal endowment cultivating land, the one being the owner and the other only a tenant, the owner makes the best use of the land, gets the largest crops, has the best cattle and the best orchard, and in all ways takes the best care of the property. The reason is very simple. It is because all the labor, skill, and economy bestowed upon the land enure to his own advantage. The net results belong to him, and this is sufficient reason for the employ- ment of his best powers and for the practice of the utmost frugal- ity. Capital arises from the exercise of industry and frugality. It is for the interest of the state that capital should be created. The system of land tenure which offers the greatest inducement to the creation of capital is the one most conducive to the public interest. Again, the private ownership of land tends to stability in in- stitutions. The ideas which gather about the word home are the most precious, both to the individual and to the community, that we are able to conceive of. A man will ordinarily undergo greater hardships, practice more self-denial, exercise more of the virtues which go to the upbuilding of the commonwealth, in order to secure a home, than to accomplish any other object. This is what his mind is first set on, and when he has gained it his efforts are equally enlisted to keep it. The single tax threatens to pro- foundly alter the meaning of this word as we understand it. It is not consistent with the idea of home that somebody should take it away from us by bidding at an auction. If it be said that no such auction would take place, but that the state would fix the tax at a rate previously ascertained as sufficient to take the eco- nomic rent, differing from the present tax only in amount, then we say that there is no means of ascertaining what the economic rent is. It would be possible to form an approximate estimate at the beginning by taking as a standard the rents paid by individ- uals for the use of land as a matter of bargain. But the standard would only serve for the first renting. What about the second ? Land values change. It is the aim of the single tax to gather in the values that grow with the progress of society. A large part of Mr. George's argument is addressed to the coming time when all available land shall be appropriated. Renting by auction is the only process that will enable society to collect economic rent surely, equitably, progressively, and scientifically. I have no apprehension that the single-tax theory will ever get beyond the argumentative stage in this country, or in any country where small ownership is the characteristic feature of agri- AGRICULTURE AND THE SINGLE TAX. 499 culture. The land-owners have so many stakes in the country, and these are driven so firmly, and woven together so tightly, that no revolution can gain head which has for its aim to dispossess them of their homes and acres, or to unduly tax them. No evidence exists showing or tending to show that agricult- ural land in the United States is capable of yielding any consider- able amount of public revenue above what it now yields under the tax laws of the several States. Evidence corroborating that cited from the Connecticut Bureau of Labor Statistics has been supplied lately in a rapidly swelling stream, especially in the offi- cial publications of the Commissioners of Vermont and New Hamp- shire, where there are literally tens of thousands of acres of aban- doned lands, which were once the homes of thrifty farmers, and which can now be had for no greater price than the present value of the improvements thereon. A remarkable letter from Judge Nott, of the United States Court of Claims, in the " Nation " of No- vember 21, 1889, presents facts and reasoning thereon, which, what- ever else may be said, show conclusively that in the fairest parts of agricultural New England there is nothing left for the single tax to sweep into the public treasury. In the presence of such facts, how idle is it for disputants to cull figures out of the census reports, as Mr. Shearman does in the " Forum " article previously cited, to show what was the value of farms in 1880, and what annual percentage they ought to yield — like measuring a man for clothes, at the distance of a mile, with a theodolite ! There is no subject more bedeviled with dogmatism than tax- ation. There is none in which dogmatism is less helpful. The more study one bestows upon it the less will he be inclined to lay down inflexible rules. While justice should be ever in the mind's eye, yet our conclusions must always be mainly experimental. Of all the dogmas on taxation the single tax on land is the most dog- matic, and the one least favored by experiment, so far as experi- ment has been made. In India the single tax has been in force from the earliest times, supplemented by other taxes only after economic rent had been exhausted. During the last half-century British India has been well governed, so that whatever bless- ings the single tax has in hiding ought there to have been dis- closed. That it has not abolished poverty, or exhibited any tendency to do so, may be confidently affirmed. There are some hundreds of professors of political economy in the colleges and universities of the civilized world. They are of various schools, including that of state socialism. Some are con- servatives, others progressives, still others may be called radicals. They are men who have somehow got themselves recognized as fit to instruct others in the principles of the science which deals with the production and distribution of wealth, with land, labor, 5oo THE POPULAR SCIENCE MONTHLY. capital, interest, taxes, etc. Of course, they have all had their attention called to the single-tax doctrine. It has been " in the air " for ten years, and it is their business to know all the discov- eries in their science, just as it is that of astronomers to know all the finds of new comets and satellites. If any one of them, either in Europe or America, has given his adhesion to the doctrine, I have not heard of him. All who have taken the trouble to give any opinion about it have spoken adversely. It can not be said that they are afraid to speak their real sentiments ; most of them are free-traders, and nothing has been more unpopular than free trade, although that tide appears now to be turning. If the single tax contains the germ of truth, is it not a little remarkable that no member of the profession should have perceived and acknowl- edged it ? ♦•♦ CHINESE SILK-LORE.* By General TCHENG-KI-TONG, SECRETARY OF THE CHINESE EMBASSY AT PARIS.

For the protection of the mulberry -trees, the raising of poly- voltines, or worms that hatch several broods a year, is forbidden * From an address given at the Orange Garden of the Tuileries, during the exhibition of Useful and Injurious Insects. f The Emperor Yu, called the Great, ascended the throne 2205 b. c, and reigned twenty- seven years. He founded the second dynasty and completed the civilizing work of the Em- peror Hoang-Ti, of whom he was a descendant. He divided each of the signs of the zodiac into two equal fractions of 15°. The farmers observe with the greatest attention the man- ner in which the several parts of this cycle follow one another, and prognosticate concern- ing meteorological phenomena from them. The observations made at Zi-ka-wei by Father Dechevrens do not lead us to suppose seriously that there was any foundation for this su- perstitious meteorology. The date of the entrance of the sun into each of these twenty-four divisions was indicated by that of the Chinese New Year. According to the calendar for 1888, as marked out by Bishop Perney's table, the 14th of February was the date for the opening of spring ; February 29th, for rain ; March 15th, for the hatching of silk-worms ; March 31st, for real spring, etc. There is nothing absurd in the idea of a connection be- tween the first electrical phenomena and the hatching of the worms ; for the early electri- cal phenomena are usually associated with an atmospheric temperature favorable to such changes.

Here I may remark that we define two periods in the molt- ings : the first, when the worms cease to take food, when we say that they lie down ; and the second, when they lay aside their envelope, which we call their getting up. We also say, when we smother them with hot water, that they are taking a bath. m i & % & % ft # %M /;''V;i, STEE^ Fig. 2. — Separation of the Worms about to spin.

This duty, which requires experience, devolves upon the matrons, while the fabrication of the thread is assigned to the young women. But the separation is hardly as absolute as is assumed by the poet. It may be seen from our figures that the Chinese women, in preparing the silk fiber, use extremely rudimentary processes ; but it must be remembered that manual labor is very cheap among the Celestials, and that, con- sequently, they have few inducements for economizing. The people, men and women, are assiduous workers, and make available instruments so rude that Westerners would find it very hard to use them at all. Only the culture of the domestic silk-worm is described in the treatise of the Emperor Kang-Hi, while the less precious though useful fiber of the wild worm is prepared in a quite different manner. CHINESE SILK-LORE. 5°3 with us, and the discovery of which goes back to ancient times. I mean the music of silk. My countrymen, even before they had invented the art of working silk and making cloths of it, had dis- covered the secret of making it musical, and of drawing from it the sweetest and most tender sounds. From the time of the Em- peror Fo-Hi (3000 b. c.) they made an instrument consisting of til M ti £ "f fr Fig. 3.— Pabkication op the Thread.

The board gradually assumed a definite shape and curvature, with measured dimen- sions. The cords were more artfully spun and composed of a determined number of fibers, and the number of them was fixed according to the character of the instrument desired. These cords, properly adjusted as to size and tension, were made to give 504 THE POPULAR SCIENCE MONTHLY. the tones of a regular stringed instrument. Such was, in short,, the origin of our first musical instruments, the kin and the die,. which were both invented by the same person and at the same time, and both give the peculiar sound of silk.* The construction of the instrument kin affords matter for an interesting study. It is made of toung-wood. The upper part is rounded, to represent the sky ; the lower part is flat, and repre- sents the earth. The abode of the dragon — that is, the upper part,, from the bridge, eight inches down — represents the eight areas of the wind; and the nest of Foung-Hoang, or the same part at four inches in its height, represents the four seasons of the year. It is furnished with five cords, representing the five planets and the five elements. Its total length is seven feet and two inches,, representing the universality of things. The inventor, by means of this instrument, first regulated his own heart and restrained his passions within just limits. He then labored to civilize men. He made them capable of obeying the laws ; of doing acts worthy of reward ; and of engaging in peaceful industry, by which they acquired the arts. Besides these five cords which give the five full tones, there are two others that give the half-tones and repre- sent the sun and moon. Concerning the construction of the che*, I will only mention that it had fifty and still has twenty-five cords ; for I perceive that I am saying too much about the music of silk. It was, how- ever, proper to give a full account of the kin, for it represents the first application of this music, f * The engravings accompanying this article are from photographs from an edition of the poem of the Emperor Kang-Hi, published at Shanghai. They show most evidently that the artist has depicted customs of a very remote antiquity. Men are employed only for operations that require strength, like the cultivation of the mulberry-tree, the collection of leaves, etc. The legends beneath the designs are free translations of the Chinese verses above them. f The inventor of the kin and the che was no other than the Emperor Fo-Hi, who reigned about two hundred years before Hoang-Ti. The invention of thread and of fire is attributed to him ; and he taught men, who had previously eaten their meat raw, to cook it. The che kept its fifty cords till the time of Hoang-Ti, when a young maiden played it before the emperor with such effect that he concluded that it was a dangerous instrument to hear, and too liable to excite the passions of the people. Instead of throwing himself at the feet of the siren, as a European monarch would have done, he in his wisdom decreed that the che should in future have only twenty-five cords. Notwithstanding IIoang-Ti's edict, the number of cords has been varied several times. There have been sometimes twenty-seven, sometimes twenty-three, and sometimes only nineteen, but no one has vent- ured to go back to fifty ; the changes having been instigated by considerations of the sig- nificance of numbers, to which the Chinese are much addicted. The che has now twenty- five strings. Each string is held by a colored bridge. The first five are always blue ; the next five red ; the next yellow ; the next white ; and the last series black. The bridges are movable, and each one is adjusted according to considerations that we shall not enter into. There are four kinds of che's, which are of different length, but of identical construction. They are played at court and in the Confucian temple. In the latter case four instrumente- CHINESE SILK-LORE. 50 5 You know so well liow our silk-worms are cultivated that I need not relate the details of the method. In principle there is not much difference between our method and yours ; possibly yours is only a copy of ours, without pretending to possess any novel features. But our system goes back to twenty-seven hundred years before Christ. The queen of the Emperor Hoang- Ti at that time first conceived the idea of raising silk-worms and of making from their production garments with which to clothe the people over whom her august husband ruled.* The indention had such a following that it is still spreading through the whole world on a growing scale. Notwithstanding we have the wool and fur of animals, silk still is and always will be an article of luxury that no one who has the means of getting it will do without, f We, who are always grateful to our bene- factors, honor the inventor of the art of silk-culture with a real perpetual cult. Besides the temples which we have erected in all the corners of the empire, her Majesty the Empress goes every year at the hatching season, in person, with all her suite, and in great pomp, to the field of the mulberry, to sacrifice to the goddess who was the queen of the Emperor Hoang-Ti.J After the cere- are used, two of which are placed in the east and two in the west. Music was regarded by the ancient Chinese as an affair of state and religion, as a science revealed from heaven, a ray of the universal harmony emanating from divinity. Celestial forces and virtue were attributed to it. It was to them the science of sciences, the one by which all others were explained, to which they were related and from which they were descended. The modern Chinese have not abandoned their notions, although the sound of their music does not suggest them to Europeans. * This celebrated woman, whose name was Loui Tseu, is adored as the goddess of silk. She was born, according to the Chinese historians, 2697 b. c, in the city of Si-Ling. Her husband was the first Chinese legislator, and reigned a hundred years — from 2*737 b. c. to 2637 b. c. — and died at the age of one hundred and twenty-one years. One of his ministers composed the famous Chinese cycle ; another constructed the celestial sphere ; and a third regulated the notes of the gamut, with which he associated a metrical system. The Chinese refer the invention of wagons, bows, spun goods, and bells — in short, the origin of civiliza- tion— to that period. f Mencius, the Chinese philosopher next in esteem after Confucius, said that after fifty years of age one could not keep warm without wearing silk clothing. It is likely that even before the time of Hoang-Ti the Chinese could make cloth of the silk of the wild worms, those that lived on the oak, for example. Another use of silk, which the author does not mention, was in the fabrication of the cords by means of which grand dignitaries received orders to strangle themselves. The messengers, who communicated the sentences to them, besides bearing the order written with the terrible vermilion, were usually instructed to proceed with the execution in case the victim had not courage to perform it himself. On the other hand, the emperor often expressed his satisfaction through gifts of balls of silk ; whence originated the expression to "present the silk " ; and this, being confounded with the sentence-bearing cords, has given rise to some curious mistakes. X The calculation of the days for the performance of the traditional sacrifices by the Emperor is one of the principal duties of the astronomers of the observatory at Pekin.

There are four full astronomers, two Chinese and two Tartars, who appear in the religious solemnities. Under the reign of the Emperor Kang-Hi the astronomers were Jesuits, and had a great influence at court. But they were denounced at Rome by the Franciscans, as favoring idolatry. A suit ensued, which the Franciscans gained, and the Jesuits had to resign their long-held functions. LETTERS ON THE LAND QUESTION 507 This ceremony, which is one of the most important of those her Majesty has to perform during the year, is a great incentive to the silk-raising population, who can not neglect their own work when they see their sovereign occupied in the same way. An old proverb says that " an idle farmer causes two persons to die of hunger, and a woman who will not weave will see ten dying of cold." The proverb illustrates the value of encourage- ment, and shows that silk- worm raising and weaving are duties of the women. — Translated for the Popular Science Monthly from La Nature. LETTERS ON THE LAND QUESTION. [ Con tinned. ] By Prof. HUXLEY, HEEBERT SPENCER, AUBERON HERBERT, FREDERICK GREENWOOD, and DARCY WILSON. PROF. HUXLEY'S SECOND LETTER. To the Editor of " The Times " : SIR : After a careful perusal of Mr. Spencer's letter in " The Times " of to-day, I fear I can only reiterate my declaration that he " has not helped us much." So far as anything said in that letter goes, it remains an open question whether Mr. Spencer agrees, in principle, with Mr. Morley's " hecklers " or whether he does not. If any one maintains that private ownership in land was originally set up by force or by fraud, and consequently has no ethical foundation, I think, as matters stand, he has a right to cite Mr. Spencer's authority in favor of that position ; and I, for one, very much regret that any person should possess that right. It seems to me lamentable that the "absolute political ethics" of to-day should have got so very little further than the point reached by Rousseau, the absolute political philosopher of one hundred and thirty years ago, who tells us that — Le premier qui ayant enclos un terrain s'avisa de dire Ceci est d moi, et tronva des gens assez simples pour le croire, fut le vrai fondateur de la societe civile.* Rousseau laments that there was no one to pull out the stakes and fill up the ditch of this primitive land-grabber ; and to warn mankind that "the fruits of the earth are everybody's and the land nobody's." These passages are cited from the famous " Discours sur l'Ori- gine de l'lnegalite' par mi les Hommes," published in 1754, in which I think will be found, implicitly or explicitly, all the propositions * [The first one who, having inclosed a field, took it into his head to say " This is mine," and found people simple enough to believe it, was the true founder of civil society.] 5o8 THE POPULAR SCIENCE MONTHLY. which Mr. Laidler discovers in " Social Statics " and attributes to Mr. Spencer. However, these are matters of opinion ; and as Mr. Spencer, leaving the main issue aside, has put me on my defense, I hope I may say a word or two to show how very easy that process is ; for, surely, nothing can be easier than to refuse to be charged with the consequences of opinions one does not hold. Mr. Spencer says that I " admit that all land-holders hold their land subject to the supreme ownership of the State " ; and his remarkable inability to see that we disagree on the land question flows out of this assump- tion. But I admit nothing of the kind. If I declare that, under certain circumstances, the State has a right to shut me up and to make me work on the tread-mill, or to hang me, or to dispose of me and my property in any other way, it does not appear to me that " by implication " I admit that I hold my property, my lib- erty, and my life, " subject to the supreme ownership of the State." Surely the State is not my owner — I am not a serf — be- cause I admit the right of the State to do these things ! It is absolutely unintelligible to me that on such grounds as those alleged any one should try to force me to the conclusion that " the community, as supreme owner, with a still valid title, may resume possession if it thinks well." And this leads me to another point. What historical ground is there for the assumption that the community (in the sense of " the State ") ever had a " valid title " as universal land-owner ? I am not ignorant that there have been and are such things as " village communities " ; and if any one chooses to assert that communal ownership is the primitive form of land-holding, I am willing, for the sake of argument, to admit that such is the case. Let the further assumption that no agencies save force and fraud have broken up the communal organization (astonishing as it is) be accepted. Well, then, I see that a sort of an argument (though I think a very fallacious one) in favor of going back to ownership by village communities might be founded on these data. But what has that to do with State land-ownership, which has not the remotest resemblance to the communal system of antiquity ? Mr. Spencer addresses a sort of argumentum ad hominem to me. It is hardly chosen with so much prudence as might have been expected. Mr. Spencer assumes that, in the present state of physiological and medical science, the practitioner would be well advised who should treat his patients by deduction from physio- logical principles ("absolute physiological therapeutics" let us say) rather than by careful induction from the observed phe- nomena of disease and of the effects of medicines. Well, all I can reply is, Heaven forbid that I should ever fall into that practitioner's hands ; and if I thought any writings of LETTERS ON THE LAND QUESTION 509 mine could afford the smallest pretext for the amount of man- slaughter of which that man would be guilty, I should be grieved indeed. Mr. Spencer could not have chosen a better illustration •of the gulf fixed between his way of thinking and mine. When- ever physiology (including pathology), pharmacy, and hygiene are perfect sciences, I have no doubt that the practice of medicine will be deducible from the first principles of these sciences. That happy day has not arrived yet, and I fancy it is not likely to ar- rive for some time. But, until it comes, no practitioner who is sensible of the profound responsibility which attaches to his office, or, I may say, is sane, will dream of treating cholera or small-pox by deduction — from such mere physiological principles as are at present well established. And if this is so, what is to be said of the publicist, who, undertaking to preserve the health and heal the diseases of an organism vastly more complicated than the human body, seeks guidance, not from the safe, however limited, inductions based on careful observation and experience, but puts his faith in long chains of deduction from abstract ethical assump- tions, hardly any link of which can be tested experimentally ? No doubt a great many foolish laws are passed. Also a great many foolish prescriptions are written ; but the latter fact is not evidence in favor of " absolute physiological medicine," any more than the former testifies to the value of " absolute political ethics." I am, sir, your obedient servant, T. H. Huxley. Eastbourne, November 15th. MR. HERBERT'S LETTER. To the Editor of " The Times " : Sir : I more than suspect that my friend Mr. Greenwood can not have escaped a few moments' quiet amusement the other morning when he read his own letter in " The Times." Mr. Spencer, after many years, slowly and cautiously modifies a view formed earlier in life, and Mr. Greenwood thereupon addresses to the whole body of philosophers, to make use of his own words, " a heavy lesson." When, currents calamo, he took the philosophers under his charge for the purposes of instruction, did it never occur to him to ask himself how many oracles of his own it is the fate of the most careful editor — be he who he may — in the course of even one short year of political warfare to recall and silently re- place by their opposites ? The philosophers may have their faults, but I am afraid they are hardly to be convicted of them by any •one who has, closely or remotely, independently or subserviently, followed the zigzags of political life. And now as regards the question itself. There are some of us who have been watching for years with great pleasure the growing change in Mr. Spencer's views about land, and have only wished 510 THE POPULAR SCIENCE MONTHLY. the change might go further. We have looked on " Social Statics" as one of the most splendid and helpful books ever written in the English language, and even the blot, as it seems to us, of land nationalization could not dim our enthusiasm for it ; and now we — in saying " we," it is not an undivided " we/' for I admit fully the divisions among individualists on this point — rejoice greatly to think that our leader has, at last, his doubts and hesitations whether land nationalization is a true article in the creed which he has taught us. May I now add some reasons to those already given in " The Times " why land nationalization is both bad as philosophy and bad as expediency ? 1. As philosophy. It is said that the land of a country belongs to the people as a whole. But if so, it is clearly the people, that is, the whole people without exception, to whom it belongs, and not a majority among them. Philosophy must be exact in her terms, and if she says it belongs to the people, she can not pos- sibly mean two thirds or three fourths, or some other unstated quantity short of the whole. It may be, I can readily understand, a matter of practical convenience to politicians and other believers in power to treat a majority as society ; but no amount of torture could wring from a Philosophy that knew what she was talking about the admission that the two things are equivalents. The deductions from this are plain. Property belonging to the whole people could never be used by any part of them, for the consent of the whole could not practically be got as regards any special use of it, seeing that every day, almost every hour, that whole is chang- ing. We can, therefore, hardly accept a theory which lands us forthwith in an absurdity. 2. If the soil belongs to society in the abstract, and if, notwith- standing the urgent remonstrances of Philosophy, we decide to interpret the word " society " by the word " majority," why is it taken for granted that it belongs to that majority of the people who at any given moment happen to inhabit it ? If the Chinese are overcrowded, or to come nearer home, if the Belgians are over- crowded, or if some part of the Russian people possesses a less attractive portion of the world to live in than our own, can they not claim with unanswerable logic that the doctrine of the major- ity has no merely local application, but must be treated in a far more comprehensive spirit ? If Philosophy says the land of right belongs to the majority, it must also answer, " What majority ? " and the nations that are now located on the least advantageous spots will not answer that question in quite the same way as the nations that enjoy the sunny side of the hedge. 3. It is claimed that the present owners may be dispossessed by force because some of them (a quantity that is diminishing LETTERS ON THE LAND QUE STL ON. 511 every day — see the yearly returns of land-sales) became possessed in old days of their land by force. But if an act of ancient force is sufficient cause to disinherit these holders of land, it must, I fear, also disinherit the whole nation, for we all came here by force. Celt, as far as we know, Anglo-Saxon, and Norman came by force, and the nation that is rather strangely asked to show its horror of past force by carrying out anew another wholesale act of force, is itself out of court for the very same offense as that under which it is proposed to condemn the land-owners. 4. All the articles of use and commerce — if we except those taken from water — are drawn in the marvelous laboratory of nature from or under the soil, or from the soil and air combined. Every tree, every crop of corn or roots, every fleece, contains in itself positively and actually so much of the soil where it was raised. Where, then, is the logic of declaring that certain parti- cles— and these the very best — when taken from the soil may be private property, while the other particles — which are generally of lesser value — left lying in the field are, by some abstract right, the property of an unknown and unstated portion of the people — called a majority — who have never yet set eyes upon their prop- erty, and could not distinguish it if they did ? My coat is now my private property ; but years ago, before the grass grew which fed the sheep, the larger part was public property. What a marvelous transformation, and what inextricable confusion both of theory and of fact ! How a thing which, as a matter of abstract right, once belonged to everybody, can rightly become my private prop- erty, I am utterly unable to understand. Perhaps Mr. George or Mr. Laidler could help me. Then for the expediency. Is the race to deprive itself, for the sake of a theory that can not hold what is put into it better than a sieve can hold water, of the immense happiness and comfort that may come to thousands and thousands of families from the per- manency of possession ? If the land belongs to the majority, can there be this permanency ? How can you let A and A's family retain forever the possession of the holding which he has indus- triously acquired, when B and C are waiting for their turn of what, without any industry or acquisitive virtue on their part, is declared to belong to them ? That A is better fitted — naturally selected — to fill the holding, to use it happily and profitably for himself and for society, must count as nothing in face of the fact that B and C have taken the trouble to be born the owners of it. Then, too, comes in all the trouble and confusion about improve- ments, where property is split into this double ownership between the abstract state and the concrete holder. Improvements, we are told, can only realize their full value if there be a free sale and fixed rents. Do any persons in their sober senses imagine that 5i2 THE POPULAR SCIENCE MONTHLY. the hungry, greedy, necessitous state of the politician will ever place itself on the same footing as it has placed the Irish land- lord, upon whom the other day it so freely practiced its cheap philanthropy ; that it will ever consent to fix its rents in per- petuity, or to abide by them if they were fixed ? Then comes all the unutterable official management, the inspectorate, the armies of surveyors and clerks, the arrogant petty kinglets, the red tape, the annoying conditions, the unending correspondence on the sub- ject of the new pump or the new road, the constant battle in Par- liament as to new methods of land-tenure, new methods to allow A to replace B in quicker succession, new forms of land-taxation, universal upsetting of existing system, and universal establish- ment of the last land fancy of the half-baked theorist. Conceive for one moment the slough of despond into which you would plunge back a vigorous, self -helping nation that had once, how- ever hesitatingly and half-heartedly, taken the first few steps along the road of individual initiative, experiment, and progress. No, it is in another direction our efforts must be turned. Years and years ago, if our political parties were not — both of them — like wild beasts fighting, with no thought or sense, but for the mad struggle in which they lie locked together, biting and tearing with tooth and claw, they would have freed the land. They would have broken the lawyer's yoke that still curses our present gener- ation and again and again prevents the ready sale, and they would have got rid of the heavy burdens of rate and tax that now fall •on land and make it an undesirable possession for the poor man. Of all pieces of stupidity none is greater than taxing land just because the rich man at present holds the larger part of it. It is like all other pieces of class legislation, branded on its forehead with the fool's mark. You strike at your supposed enemy and wound yourself. Land must be made free in the only true sense — free from the clutch of the lawyer, free from the visits of the tax and rate collector, and it will then become the greatest source of happiness and comfort to our people. Once really freed, the industrious, vigorous poor will slowly wrest it from the rich man, paying, as has been seen in France, notwithstanding the heavy State burdens on land, a price that the rich man will not pay for its acquisition. Above all other forms of investment for the poor man, land is far away king. It is no pig in a poke for him. He knows it, he understands it in all its good and bad qualities better probably than any other living man ; he can not be juggled out of it, when it is once bought, by the carelessness or fraud of direct- ors ; he can put all his spare time and spare labor into it. It is not, however, a question of the agricultural laborer alone, but also of the saving mechanic in town, who would look forward to the 'bee farm, or flower or fruit farm, on which he might end his days. LETTERS ON THE LAND QUESTION. 513 It is not only a question of the townsman ; it is also a question of co-operative and trade-union societies, who also would learn to put their investments in land, perhaps producing for themselves, and offering in many cases opportunities of country life to their members who needed rest and change. Unless we persist in follies upon follies in the shape of legislative interferences ; of expensive machinery to provide the people with land — machinery that will defeat its own object, for it must be paid for out of the rates, and will therefore increase the burdens on land ; of forced agricultural agreements between landlord and tenant that tend to stereotype all farms in their present size ; of State-hired allotments that, as in the case of our benighted dealings with Ireland, must tend to weaken the desire for ownership, the land of this country, now thrown upon the market at prices so far below its real value, in- dustriously acquired and held in firm, unalterable fee-simple, will prove the greatest blessing to all classes of our working people. All that is wanted is to keep land free — free alike from Radical messing and Tory messing, and leave it what it naturally is — until spoiled by that blessed politician whose eternal finger finds its way into every pie — the sweetest reward for a man's labor and the most powerful incentive to undergo those labors. If you wish to develop all the virile virtues of our English country folk, and to place before them a worthy goal for their life-efforts, sweep away every obstruction and make it easy for them to gain their own home, held neither at the will of the land-owner nor of that worse modern creation — the changing majority inside Parliament. I notice that Mr. Spencer still allows himself to think of that ogre, the land-owner, who might clear a district if so minded. That is true ; but may I submit to him that it is equally true of a majority, and in one sense more true ? A parliamentary majority which once considered itself lord and master of the soil might play any prank under high heaven that once occurred to it. It would be quite likely to turn a perpetuity into a thirty years' ten- ure, or a thirty years' tenure into a fifteen years' tenure, or to revolutionize every home in England in deference to the last notion that had got uppermost in its infallible head. Moreover, it should be seen that once the spirit of individualism begins to get hold of our people, the action of the landlord who cleared the estate would serve to redouble the efforts of the people to become absolute owners of their property. Unconsciously he would be the instrument of a good greater than the harm he had caused. We have not yet sufficiently profited by Mr. Spencer's teaching to recognize the enormous stimulus for good which there is in every form of evil when once we are fairly on the track of fighting it with the true self-helpful remedies. "What delays and impedes the human race is far less the evil that abounds than the false vol. xxxvi. — 33 5 14 THE POPULAR SCIENCE MONTHLY. remedies which, we apply to cure it. It is hardly too much to say that human improvement is due to the evils and difficulties of life overcome in the right way. One last word. Men doubt about " absolute political ethics." Yet they do not doubt about absolute principles in physics, in chemistry, in biology, in psychology, or even in the ethics of pri- vate life. Does it never strike them that it is a mightily strange thing — requiring, I think, some explanation on their part to which they do not often condescend — that we should live in this world almost surrounded by order, or fixed law, on every side of us, and yet in one special department of it — that of political action — this order should suddenly he replaced "by disorder and uncertainty ? Does it never occur to them that this strange inexplicable contra- diction may be not in nature, but possibly only in their own minds ? Does it never occur to Prof. Huxley, who is not an ad- mirer, I suspect, of our party warfares, that the danger of modern civilization, the unscrupulousness, the corruption, the cowardice, the shiftiness, the untrue motives that flourish in public life have their stronghold in this belief that politics are an Alsatia, where alone in the wide universe the writ of the Great Power does not run ? Does he not see that as long as politics are held to he out- side moral law and scientific statement so long we shall he at the mercy of all those who for their own purpose try to persuade the people to believe the ignoble creed that whatever they desire is right, that the measure of their wants is the measure of the just and true ? Some day, when possibly men may have forgotten "the heavy lesson" my friend Mr. Greenwood addresses to the philosophers, they may, warned by the great social dangers press- ing upon them, turn round and see the full meaning of Mr. Spen- cer's work, and understand that he alone has pointed to them the path that leads out of the wilderness. May I say that I am always glad to send some of our individ- ualist tracts to any person who writes to me ? I am, very faithfully, Auberon Herbert. Old-House, Ringwood, November 14th. MR. GREENWOOD'S SECOND LETTER. To the Editor of "The Times " : Sir : If the question is whether Mr. Herbert Spencer is right in endeavoring to purify the conduct of public affairs and dis- charge it of error by establishing a system of " absolute political ethics, or that which ought to be," I submit that he need not have said so much as he has lately said in your columns. Who doubts that he is right ? Who doubts that he is wisely and nobly em- ployed when his business is to discover the bases of true political morality, and to exhort mankind never to lose sight of them, what- LETTERS ON THE LAND QUESTION. 515 ever may be the stress of expediency or compulsion in the world as we find it ? But is that the question that was raised on the conversation between Mr. Laidler and Mr. Morley at Newcastle ? Not at all. By that conversation we saw in a remarkably plain way that large numbers of the most intelligent and powerful rep- resentatives of labor in this country had derived from Mr. Spen- cer's teaching these conclusions : That private property in land is a public wrong based on force and fraud, and that to right one wrong it is sometimes necessary to do another. This they took to be a lesson in practical politics ; and what it points to, in practice, is perfectly clear. Resume possession of the stolen land, if you please, for as private property it still is, and under its present ownership it must ever remain, a wrong to the community. For the rest, though compensation must be made for whatever is in the land which was not in it when it was stolen, yet to right one wrong it is sometimes necessary to do another. That is the point for attention as the matter stands at present. For though Mr. Spencer tells the people, as he could and should have told them from the first, that just compensation would entail a disastrous outlay, infallibly to become more disastrous through inferior man- agement of the land by public officials, what of that if, to right one wrong, it is sometimes necessary to do another ? What of just compensation, if it makes a standing crime against the com- munity completely irremediable, and if the people are at liberty to decide whether this is not a case where to right one wrong it is necessary to do another ? The point has been actually considered by labor societies and the leaders of the new Socialist movement all over the country, and it seems quite clear that the Newcastle Labor Electoral Association, for one, has come to the conclusion that, morally, there need not be much punctilio about compen- sation. But perhaps Mr. Spencer has never said that to right one wrong it is sometimes necessary to do another. In one of his letters to " The Times " he wrote that he could not be positive whether he had or not ; which seems to imply that he would not be surprised to learn that at one time or another he had included this doctrine in his teaching of absolute political ethics. Be that as it may, however, he could have told us when he was challenged on the subject whether this is his teaching now or not. He has written three letters ; we remain in the dark on the most important point of all, and at the close of an argument entirely occupied with a defense of propagating " absolute political ethics " Mr. Spencer announces his determination to go no further with the contro- versy. Meanwhile here is Mr. Laidler in his old position, and here left. To be sure, it seems difficult to include the dogma he rests upon in any system of absolute political ethics ; and if Mr. 5i6 THE POPULAR SCIENCE MONTHLY. Spencer had not said that he could not be sure that he had never preached it, we might conclude without further inquiry that the doctrine had never been his. As matters stand it would be an extremely good thing if he could assert that he does not hold it now, anyway. That done, his counsel against the nationalization of the land as a fatally bad bargain (since it must be carried out on just compensation principles if at all) would have full effect. It is to be hoped that Mr. Laidler's questions in "The Times " of to-day will be answered, and they will be if Mr. Spen- cer does not turn his back on doubting disciples who cry to him. Your obedient servant, Frederick Greenwood. November 15th. MR. WILSON'S LETTER. To the Editor of " The Times " : Sir : Mr. Laidler has given us a digest of the ninth chapter of Mr. Herbert Spencer's " Social Statics/' and asks triumphantly, " Does it not constitute an unanswerable argument in favor of the nationalization of the land ? " Mr. Spencer has modified the views expressed in that work, but, as Mr. Laidler now elects to stand or fall by them, it may perhaps be worth while to inquire how far they support his proposals. The nationalization of the land, as defined by Mr. Laidler in his interview with Mr. Morley, means that the land, but not the houses, of this country should, on the death of the present owners, revert to the nation or State without any payment therefor. In the " Social Statics " it is argued that each one of the race of beings born into the world has equal rights to the use of this world, and that no one or part of such race of beings may use the earth in such a way as to prevent the rest from similarly using it. From this it follows that land can not justly become the property of individuals ; but it also follows that no given portion of the globe can justly become the property of any individual nation, for that would be to deprive the rest of "mankind at large," the rest of " the human race," of their equal rights. It is true that Mr. Spencer in one place says that under his system, instead of leasing his acres from an isolated proprietor, the farmer would lease them from the " nation." But this can only be reconciled with the rest of the chapter if the nation is under- stood to be acting as the " agent or deputy agent " of the commu- nity at large. According, then, to the argument in the " Social Statics," the land of this country should belong, not to individuals nor to the State, but to the human race. Mr. Spencer is also in favor of giving existing owners compen- sation. On this he says that — Great difficulties must attend the resumption by mankind at large of their rights to the soil. Had we to deal with the parties who originally robbed the LETTERS ON THE LAND QUESTION. 517 human race, we might make short work of the matter. But, unfortunately, most of our present land-owners are men who have, either hy their own acts or by the acts of their ancestors, given for their estates equivalents of honestly earned wealth, believing that they were investing their savings in a legitimate manner. To justly estimate and liquidate the claims of such is one of the most intricate prohlems society will one day have to solve. What Mr. Spencer advocates is, in short, that the land should revert (a) to the human race, (b) after payment of compensation. And it seems to be generally admitted that the compensation would amount in the shape of interest on purchase-money to a greater sum than is now paid in rent. So far, Mr. Laidler and Mr. Spencer do not seem to have much in common. The one point on which they do agree is that the existing titles to land are not legitimate, because they are founded on " force or fraud." Let us apply this view to England. When this country was conquered by the Normans the land fell into the hands of the sovereign, or, in other words, the State. It was then granted out in part to Normans, and in part to existing owners. How can it be said that the grantees obtained their land by force or fraud ? They obtained it by grant from the State. The title of the State which made the grants did, no doubt, depend on conquest or force. But if this fact is to invalidate the title of existing owners, it must, a fortiori, utterly destroy the title of the State to resume its possession to-day. The schemes, then, for dealing with the land appear to be three in number : (1) Mr. Laidler's, that the land should revert to the State without compensation ; (2) that it should so revert with compensation ; (3) Mr. Spencer's, that it should revert to the human race with compensation. Of these, the first has been truly described as robbery, and the second as folly. The third seems to be a philosopher's dream. I have the honor to be your obedient servant, Darcy Wilson. Boodle's, St. James's Street, November 16th. MR. SPENCER'S THIRD LETTER. To the Editor of" The Times" : Sir : I suppose I may make a denial without continuing a con- troversy ; and, unless I make it, a grave charge against me will remain unrebutted. Over and over again Mr. Greenwood refers to the statement that I have said that " to right one wrong it is sometimes neces- sary to do another," and apparently wishes to force it upon me notwithstanding what I supposed was a sufficient repudiation. Being unable to recall all the contents of some ten thousand pages, written during forty years, I said as much as it seemed pos- 5i8 THE POPULAR SCIENCE MONTHLY. sible to say with, reason; for it has sometimes happened that opinions have "been quoted with approval as mine which I had quite forgotten were mine. I therefore wrote, " My belief is that I have not said this in any connection." That is, I am absolutely unconscious of ever having written it, and do not believe I ever did write it. I do not see what more was required. Mr. Green- wood urges that I have not repudiated it even now. It never oc- curred to me that, after what I said, this was needful. But, as he thinks otherwise, I very willingly repudiate it, both for the past and the present. Even did I wish to continue my discussion with Prof. Huxley, it would be ended by his letter. From it I learn that the princi- ples of physiology — as at present known — are of no use whatever for guidance in practice ; and my argument, therefore, collapses. I am, etc., Herbert Spencer. Athenaeum Club, November 18th. PROF. HUXLEY'S THIRD LETTER. To the Editor of " The Times " : Sir : It seems to me to be a pity that the discussion which has been carried on in your columns should come to an end before Mr. Laidler's able letter of the 15th instant has been considered on its merits. I conceive it to be a matter of vital importance to the whole nation that the representatives of labor should be under no misapprehension with respect to the grounds of any action they may think fit to take. And as, all my life, I have done my best to bring sound knowledge within reach of the work- ing classes, I trust that they will do me the justice to believe that I am actuated by no other motive now. Let me say, at the outset, that I have expressed no opinion, and that I do not intend to express any opinion, as to whether State ownership of land is desirable or not. If it can be proved by arguments, having some foundation in practical experience, that the abolition of several ownership in land and the substitu- tion for it of State ownership is essential to the welfare of the people, no one would feel more bound to give practical effect to that demonstration than I. In Mr. Laidler's letter, however, such arguments are not em- ployed. On the contrary, he adopts the method of Rousseau and his followers, which, consists in making certain assumptions about matters of ethics in the first place, and certain assumptions about matters of history in the second place, and then drawing the obvious conclusion that the assumed facts are in sad disaccord- ance with the assumed ethical rules. It is a delightfully easy method, and saves all the trouble of going deeply and thoroughly LETTERS ON THE LAND QUESTION. 519 into the foundations of ethics and the truth of history which the scientific plodders give themselves. Now, I do not propose to discuss the ethical assumptions set forth by Mr. Laidler. Let it be granted, for the moment, that " equity does not permit property in land/' and that " men are equally en- titled to the use of the earth." Well, starting from those axioms, I fail to see by what logical process one gets at State ownership. If " equity does not permit property in land/' how does it contrive to permit State ownership ? The State is only a name for a body of men ; and, if " all men are equally entitled to the use of the earth," why have Englishmen any more .right of property in the soil of England than Frenchmen or Germans, or, for the matter of that, the natives of Timbuctoo, have ? Thus it is the logical consequence of the doctrine of the Rous- seauites that nations are as much usurpers as individuals, and that there can be no valid title to land until the whole surface of the habitable globe has been thrown into hotchpot, and that share which every man may enjoy the use of, without damage to his neighbors, determined by a cosmopolitan plebiscite. Thus, if we are to appeal to logical consequences, those of the principles adopted by Mr. Laidler's authorities are just as startling as those of the principles of the advocates of the " abso- lute " rights of private property. And I would put it to Mr. Laidler, as a man conversant with the practical side of life, whether this does not suggest to his mind that modes of reason- ing which lead to obvious absurdities must be fundamentally vicious ? Now let us turn to the historical assumptions of Mr. Laidler's authorities. They affirm that several ownership of land origi- nated in force and fraud — whereby the nation, in whom the own- ership was previously vested, was robbed of its rights. And from these data they argue that the nation is justified in " re- suming " its " rights to the soil." Now, this is an assertion as to a matter of historical fact which can be tested. In the course of the last thirty years a vast amount of evidence has been obtained respecting the manner in which land is and has been held by people in an early stage of civilization all over the world. And resting on this founda- tion of laboriously ascertained truth, is the conclusion that the tenure of land by communities is that which most extensively prevailed in remote antiquity. What this exactly means will per- haps be best made plain by the supposition that the land in every parish in England was owned, not by one or more private indi- viduals, but by the males of one or more resident families, form- ing a corporation in which the ownership vested. The land of the community, in fact, resembled an entailed estate, which 520 THE POPULAR SCIENCE MONTHLY. should be inherited by all the males of a family collectively, they being forbidden to alienate any portion of it. This " joint family " or " village community " system, there- fore, so far from denying the right of several property in land, is founded upon that right. Assuredly, our ancestors did not trouble themselves much about the philosophical foundations of property. But I am well assured that if any one had tried to persuade a village community that all mankind had as much right as they to their land, that missionary of " absolute political ethics " would have been short-lived. It may be said that I have been talking about the archaic ex- istence of " several " property in land, while the question is about " personal " property. But is that so ? Are the land reformers going to exempt corporate several ownerships in land, when they abolish personal ownerships ? If so will they explain why cor- porate several ownership is less an infringement of the rights of mankind in general than personal ownership ? But if corporate several ownership is not " permitted by equity " any more than personal property — if the archaic communities had no more valid title than the squires who have succeeded them — whence comes the evidence that those rights of " mankind at large " to the use of the soil, which we are told they are to " resume," ever existed ? Let us, then, clear our minds of all the cant of " history after the manner of Rousseau." Genuine history shows that, as far back as the constitution of settled society can be safely traced, several property in land was recognized and acted upon. It also affords much ground for the belief that individual property was recognized in the case of the clearer of forest land ; that either individual or family several property was recognized in the case of the plot of land in which the house was situated ; and that, in bringing about the change from collective to individual sever- alty, industrialism has been just as important a factor as milita- rism. State ownership may be right or wrong, but those who sup- pose it to be a resumption by the people of a right they ever exercised, or even claimed, are at variance with the plainest teach- ings of history. I am, sir, your obedient servant, T. H. Huxley. Eastbourne, November 19th. P. S. — Mr. Spencer, in the letter which you publish to-day, says that he learns from me that " the principles of physiology, as at present known, are of no use whatever for guidance in prac- tice." I think that Mr. Spencer must have achieved this feat of learning by his favorite a priori method, for nothing of the kind is discoverable by mere observation and deduction in what I have said. No phrase of mine is inconsistent with my belief that the principles of physiology, like those of ethics, are of great use, so LETTERS ON THE LAND QUESTION. 521 long as they are applied with that caution and discretion which are to be gained only by practical experience in medicine or in affairs. If Mr. Spencer were acquainted with the history of medicine or with the present relations of physiology and thera- peutics, he would have been unable to learn from me that which it would have been ridiculous in any one to teach. MR. GREENWOOD'S THIRD LETTER. To the Editor of " The Times " : Sir : Without meaning to do so — I am quite sure of that — Mr. Auberon Herbert has placed me in a false light. It might be sup- posed, from a letter in which he deals with much more important things, that I had reproached Mr. Herbert Spencer with changing his opinions, which would be great presumption. That, however, I have not done ; and, indeed, there is no reproach in changed opinions when they are not fundamental, and when the one judg- ment and the other are not based on the same unaltered data. My complaint was against the publication of imperfect theories of social reform " unaccompanied by a clear statement of whatever reasons are fatal to their application in this work-a-day world," the point being that certain doctrines of Mr. Spencer's, acknowl- edgedly ill-considered and so unaccompanied, had gravely misled large numbers of men eager for social revolution. That is a very different thing from complaining of reasonably changed opinion. Mr. Auberon Herbert seems also to make out that, on the ground of reasonably changed opinion alone, I presume to impose "a heavy lesson" on political philosophers. It would have been arrogant indeed if I had so described my interference, as Mr. Auberon Herbert suggests. But here he does me wrong alto- gether. My account of the matter was that the conversation be- tween Mr. Morley and Mr. Laidler, together with Mr. Spencer's letter on that conversation, conveyed " a heavy lesson " to political philosophers. That is what did it. I had nothing to do with a lesson ready made. The controversy has been extremely useful — thanks to your liberal publication of it — and will do a world of good all round, especially after Mr. Spencer's welcome letter of to-day. Your obedient servant, F. Greenwood. November 19th. Prof. Chookes expresses the opinion, pertinent to his researches on the rare earths, that while, besides compounds, we have hitherto recognized merely ulti- mate atoms or the aggregations of such atoms into simple molecules, it is becom- ing more and more probable that between the atom and the compound there is a gradation of molecules of different ranks, which may pass for elementary bodies. For these bodies he offers the provisional name of "meta-elements." Their true character should be the subject of future unbiased research. 522 THE POPULAR SCIENCE MONTHLY. EXERCISE FOR CHEST DEVELOPMENT.* Br FEKNAND LAGKANGE, M. D. HOW is it that the lungs can increase in size through athletic exercise ? By a mechanism well known in physiology, by the filling out of certain air-cells ordinarily inactive, which only come into play during forced inspiration. The expansion of the pulmonary vesicles is complete in proportion to the quantity of air introduced. The atmospheric air drawn into the lungs by a very powerful inspiration seeks out the most obscure corners, and inflates the air-cells of certain regions which ordinarily have no part in the respiratory function. A definite increase in the volume of the lungs is the conse- quence of frequent repetition of this supplemental respiration. The air-cells which are as a rule inactive, and which are reserved for cases of excessive respiratory strain, arise from their inaction ; their walls, which are usually collapsed, and even stuck together, separate and give entrance to the air which can not find room in the confined space sufficient for ordinary breathing. If the forced inspirations are often repeated, the air-cells, the action of which has thus been accidentally solicited, come in the end to associate regularly in the ordinary respiratory movements. They are then very quickly modified in the sense most favorable for efficient working, according to the law we have so often pointed out, of the adaptation of organs to the functions they perform. Thus, forced respirations result in a modification of the struct- ure of certain regions of the lung, and in making them work better. Under the influence of unusual exercise the vesicles in- crease in size and contain more air. More blood is also supplied to them. Their capillary network becomes richer, and their nu- trition more active. Thus in the end they take up more room. It is in this manner that the regular working of a great num- ber of air-cells, ordinarily inactive, can rapidly increase the size of the lungs. If we follow out the modifications produced by forced respira- tions, we see that the lungs thrust outward the thoracic walls to make more room for themselves. During inspiration the ribs, by rising, favor the inflation of the lungs ; but in this case it is the lungs which, having increased in size, thrust the ribs upward and keep them raised even in the condition of repose. Hence an in- crease in the circumference, and a vaulted conformation of the thorax. * From advance sheets of the author's work on " Physiology of Bodily Exercise," in the " International Scientific Series," to be issued shortly by D. Appleton & Co. EXERCISE FOR CHEST DEVELOPMENT. 523 It is then from within outward that the force capable of ex- panding the chest acts, and it is in reality to the lnngs and not to the muscles that the chief share in the changes in form and size of the chest belong. The most powerful inspiratory muscles can not raise the ribs, unless the lungs participate in the movement of expansion, and, on the other hand, the lungs can raise the ribs without the aid of the muscles, for the chests of emphysematous patients remain vaulted in spite of their efforts to lower the ribs and complete the expiratory movement. If we sum up the facts we have just enunciated, we shall be driven to the conclusion that, in order to raise the ribs and get rid of the vicious conformation of flat chest, we must not seek to act directly on the thoracic muscles, but to produce as extensive respiratory movements as possible. There are two methods of amplifying respiration : one con- sists in voluntarily expanding the thorax in all directions. This method is in the domain of " chamber gymnastics " ; it has been much extolled, and it may give good results. The other method comes more directly into the field of our studies. It consists in in- creasing by exercise the amplitude of the respiratory movements. The problem has now become clear and definite. "We need, in order to develop the chest, to know what exercises are most fitted to produce a series of very extensive respiratory movements. Now, the amplitude of respiration, as well as its frequency, is in direct ratio to the intensity of the respiratory need, and we know that the intensity of this need depends on the quantity of me- chanical work performed in a given time. The exercises which cause an accumulation of work are, then, those most fitted for increasing the size of the thorax, and for demanding increased work from the lungs. And we know that this accumulation of work occurs especially in exercises of strength and speed. Thus the mechanism of exercise, its performance by the aid of these muscles or of those, are of secondary importance in pro- ducing the result of which we are speaking. It matters little by what process the muscular force is expended, provided that there is great expenditure in a short period of time. It is indifferent whether the movements are very slow, each of them representing a great number of kilogrammetres, or whether they are extremely rapid, each movement representing but a moderate effort. It is merely necessary that the sum of work represented by these movements, whether few or many, should be considerable in a short time. Now, the quantity of work which a given muscular group can perform in a given time is subordinated to the strength of this group. There are muscular groups which are too weak to ex- 5 24 THE POPULAR SCIENCE MONTHLY. pend much force in a short time. One arm may use its whole strength without its work representing, in the unit of time, a great number of kilogrammetres. So, whatever form the exercise takes, if the arm alone is working, we shall not find that the breathing is much quickened. The exercise may induce local fatigue before the intensity of the respiratory need has increased. It may even happen that the work of both arms together does not, after a given time, amount to enough to demand more ample respirations. In general, the exercises which are performed with the legs represent more work than those which are performed with the arms. The muscles of the upper limbs could not support, without extreme fatigue, an expenditure of force which will cause no effort to the lower limbs. It is not tiring to any one to walk five hun- dred metres in five minutes : what gymnast could traverse the same distance in the same time hanging by his hands from a stretched rope ? The total mechanical work would be, however, the same — displacing the same weight through the same horizon- tal distance. We must not, then, trust to the muscles of the arms to expand the chest. Muscular exercise can only lead to the development of the thorax in an indirect manner, and in no way by a direct effect comparable to the increase in size of a muscle which works. The muscle which contracts often becomes larger because its nutrition is more active. But the chest only expands when the surcharge of the blood with carbonic acid creates a need of a greater quan- tity of oxygen for haematosis. It is to the more active respiratory need, to the " thirst for air," that the instinctive movement by which the ribs are more ener- getically raised is due, in order to draw into the lungs a greater quantity of air. The thirst for air, carried too far, produces breathlessness, which is nothing else than a powerless struggle of the system seeking in vain to satisfy a need. When breathlessness is very moderate, it causes very ample respiratory movements ; but when it is excessive, the breathing becomes very shallow as well as very rapid. So that exercise has no longer any effect in expanding the chest when breathlessness reaches an extreme degree. To sum up, the most profitable way of dilating the lungs, devel- oping the thorax, and expanding the chest, consists in the per- formance of exercises capable of increasing the respiratory need, without pushing them so as to produce an extreme degree of breathlessness. If we pass from physiological explanation to observation of facts, we see that practice gives a striking confirmation of theory. EXERCISE FOR CHEST DEVELOPMENT. 525 Exercises of strength lead rapidly to an increase in the size of the thorax. It is the same with exercises of speed when they need very energetic movements. No exercise develops the chest as rap- idly as does running, unless it be wrestling. Mountaineers all have large chests, and the Indians who live on the high plateaus of the Cordillera in the Andes have been noted for the extraordinary size of their chests. This great de- velopment in mountaineers is due to two causes which act in the same direction : frequent ascent of steep inclines, and constant residence at great heights at which the air is rarefied. The climb- ing of these slopes needs a great quantity of work, which causes increase of the respiratory need ; respiration in a rarefied atmos- phere obliges a man to take deeper breaths in order to supple- ment, by the quantity of air breathed, the insufficiency of its vivi- fying properties. Singers, with no other exercise but singing, acquire great re- spiratory power and a remarkable increase in the dimensions of their chests. Numerous observations prove that it is enough voluntarily to take a certain number of deep breaths every day, to produce, in a short time, an increase in the circumference of the chest which may amount to two or three centimetres. If we wish to gain the same result from muscular exercise, we must choose a form of work which will increase the intensity of the respiratory effort — that is, an exercise which brings powerful muscular masses into action. We shall thus perform a great quantity of work in a short time without producing fatigue. Now the legs, which possess three times as much muscle as the arms, can perform thrice the quantity of work before being fatigued. The lower limbs are, then, more capable than the arms of awakening the respiratory need, which is proportional to the expenditure of force. Thus it is an error to demand from gymnastic exercises prac- ticed with appliances, exercises of suspension or support, any development of the chest. The trapeze, the rings, the parallel bars, quicken respiration much less than running. These exer- cises cause an increase in the size of the muscles, and even of the bones of the regions which work, but they cause very little increase in the dimensions of the thorax. Men who do much work with their arms have often a confor- mation which is very imposing at the first glance. They have sometimes broad shoulders ; but if the arms have done the work alone, without the assistance of the muscles of the trunk, we easily see that the apparently large size of the thorax is due to an excess- ive development of the muscles about the shoulder- joint, and not to raising of the ribs. 5 26 THE POPULAR SCIENCE MONTHLY. Thus we are on the wrong road when we look for too ingenious means for developing the chest ; this result, precious above all, can be obtained without any complicated appliances, without any difficult process ; and if we had to formulate concise advice on this subject we should say : When a young person has a narrow and flat chest, recommend running if he be a boy, or skipping if a girl. ♦»» CANADIAN ASBESTUS: ITS OCCURRENCE AND USES. By J. T. DONALD, M. A., PROFESSOR OF CHEMISTRY, MEDICAL FACULTY, BISHOP'S COLLEGE, MONTREAL. ASBESTUS is a singular mineral, whose characteristics are well - indicated in the various names by which it is known. The French Canadian miners call it pierre a colon — i. e., cotton-stone. The Germans speak of it as Steinflaclis, stone-flax ; and amianto, the Italian name, indicates that which is undefiled, in allusion to the fact that it may be cleansed by fire. Asbestus, the name by which it is generally known, is a Greek word, signifying endless, ceaseless, and points to its fire-resisting properties. Asbestus is, then, a mineral occurring in a fibrous form, the fibers being so fine and flexible that they may be spun and woven as cotton and flax are ; and, moreover, the fabric so obtained is capable of resisting a very high temperature. Some varieties are said to have resisted a temperature of 5,000 ° Fahr. It must be noted, however, that although this mineral is infusible, except at extremely high temperatures, its fibers lose their flexibility and become brittle at a temperature only sufficiently high to deprive it of the water which forms a part of its composition. By the mineralogist the term asbestus was originally applied to a finely fibrous form of hornblende ; but, as Dana adds, much that is so called is a fibrous form of serpentine. Most if not all the as- bestus of commerce is fibrous serpentine. A recent analysis made in the writer's laboratory showed the following composition : Silica 39-05 per cent. Magnesia 40-07 " Alumina 3-G9 " Oxide of iron 241 " Water 1448 " Undetermined -30 " 100-00 This mineral has been known from very early times, but it is only within recent years that it has found any extensive applica- tion in the various industrial arts. In ancient Greece the bodies CANADIAN ASBESTUS. 527 of those who were to be burned upon the funeral pyre were wrapped in asbestus cloth, that their ashes might be kept sepa- rate from those of the pyre. In the eighth century Charlemagne is said to have had an asbestus table-cloth, with which, when the feast was over, he was wont to amuse his rude warrior guests by throwing it into the fire, and in a short time withdrawing it cleansed and uninjured. On the other hand, the first Canadian deposit was opened only in 1878, and the owners experienced considerable difficulty in dis- posing of their output, which for the season did not exceed fifty tons. In 1889, with a Canadian output for the year of nearly five thousand tons, the demand is in excess of the supply, and is in- creasing, with prices showing an upward tendency. The asbestus of commerce is the product of two widely sepa- rated countries — Italy and Canada. The Italian article was first in the market, but the Canadian product soon made for itself a place and a name, and the mineral is now shipped from Canada to Italy ; while toward the close of 1889 the United Asbestus Com- pany, Limited, of London, England, which controls the Italian mines, acquired property in the Canadian field, and is equipping the same with a complete plant preparatory to operations on a large scale. It is very evident, then, that the Canadian fiber is, to say the least, no mean factor in the asbestus industry. Canadian asbestus occurs in serpentine, being, as already ex- plained, a fibrous form of this mineral. In two great geological formations represented in Canada there are extensive areas of ser- pentine, viz. — the Laurentian, which, beginning on the coast of Labrador, stretches westward beyond the Great Lakes ; and the Quebec Group, a formation occupying a large portion of the province of Quebec lying between the river St. Lawrence and the United States boundary. In the serpentine of both these for- mations asbestus occurs, but as yet it has not been proved that the asbestus veins of the Laurentian serpentines are sufficiently persistent to warrant mining operations. It is not improbable that productive areas may yet be found in the Laurentian rock, as prospectors are now turning attention in this direction. But at present it is only in the serpentine of the Quebec Group that productive mining is carried on. In this formation there is a belt of serpentine rock "which extends with tolerable directness, though with frequent breaks, northeastward from the Vermont boundary to some distance be- yond the Chaudiere River," which flows into the St. Lawrence near the city of Quebec. Throughout the whole of this belt there are indications of the occurrence of asbestus, but the present pro- ductive area comprises only a very small portion of this extensive belt. Although good workings occur elsewhere, the great majority 5 28 THE POPULAR SCIENCE MONTHLY. of the mines are along the line of the Quebec Central Railway, which runs from the city of Quebec to Skerbrooke, the capital of the so-called Eastern Townships of Canada, and cluster around two points a short distance apart and about midway between the two cities. In this district the serpentine forms a very rugged coun- try, rising into bold peaks and ridges, the ruggedness and boldness being enhanced by numerous faults and dislocations of the rock. Bush-fires have recently passed over much of it, and the partially burned trees, with the scarred and seamed rocks as a back-ground, constitute a somewhat drear and dismal scene. In the serpentine the asbestus forms irregular veins, varying from mere threads to four, six, and occasionally even more inches in width. The fiber is always at right angles to the sides of the vein, unless thrown otherwise as a result of faults. In some cases the mineral has been found concentrated in- pockets, from which several tons have been taken. The color of the asbestus in the veins is white, greenish, or yellow, but near the surface the veins are frequently more or less discolored from infiltration through the shattered rock of water carrying oxide of iron. At a depth, and where solid rock is reached, this trouble usually ceases. The asbestus veins are frequently traversed by bands of foreign mat- ter, such as compact serpentine, chromic and magnetic iron, and these, of course, lessen the value of the veins in which, they occur, since they cut up the fiber and must be removed at considerable trouble. Associated with the asbestus one usually finds a considerable quantity of coarsely fibrous mineral, for which, as yet, no use has been found, together with foliated and slaty forms of serpentine. Some of the latter are of very singular appearance. To use the words of an English gentleman who spent some time in the Canadian asbestus region, " Many of these fragments, as they lie on the ground after blasting, have so much the appearance of a wood-cutter's choppings that, if placed side by side with actual choppings from rough timber, exposed to the weather, the one could in no way be distinguished from the other except, of course, by handling." Others, again, in color and shape very much re- semble strips of fancy confectionery. Still another singular associate of the asbestus is a mineral of a white or green or yellow color, occurring in thin veins. When first exposed it is so soft that it may be easily indented by the finger-nail, but on contact with the air it soon hardens and as- sumes an appearance somewhat like porcelain. Analysis shows it to be closely related to serpentine. Mining is carried on by cutting down the hills of asbestus- bearing serpentine, much as a farmer cuts down a stack of hay or straw, or by open quarrying on the level. The rock is blasted CANADIAN ASBESTUS. 529 out and the asbestus, separated from the containing rock, is " cobbed " — i. e., separated by hammering from adhering foreign matter. This " cobbing " is a comparatively easy matter in the case of the finer quality, as it usually separates readily from the gangue, but in the lower grades much difficulty is experienced in separating the fibrous matter from the non-fibrous. At best there is great waste. Much of the asbestus is in thin or narrow veins, and is wasted, as by the present mode of operating it does not pay to separate this from the serpentine. A machine that will enable these narrow veins to be utilized is a desideratum. When " cobbed " the asbestus is graded according to purity, color, and length of fiber into three grades and bagged for ship- ment. The finest quality or "firsts" finds ready sale at prices ranging from $80 to $110 per ton ; " seconds " fetch from $50 to $70 per ton ; while " thirds " may be valued at $13 to $15 per ton. In good mines the yield of asbestus is from three to five per cent of the rock quarried, and the cost of mining may be put down at $25 to $30 per ton. Returns obtained by the Geological Survey of Canada show that, for the year 1888, Canada's output was 4,404 tons, valued at the mines at $255,000, and this the output of nine different mines. Over three fourths of the whole was shipped to the United States ; small quantities going to Great Britain, Ger- many, France, Belgium, and Italy, and being used in domestic manufacturing. Judging from the results obtained in the mines now worked, and the indications in other parts of the serpentine belt, it may be safely said that the asbestus deposits of Canada are well-nigh inexhaustible. There is every prospect that the industry will rapidly expand, as capitalists are turning attention to it, the work hitherto done "proving conclusively that mining for asbestus, when properly conducted, shows a more steady return for the money invested, with less elements of risk, than mining for any other known mineral." Upon its non-conducting power and its ability to resist high temperature depend the many varied uses of the mineral. First and most important are its applications in connection with the steam engine and boiler. For packing pistons, flange joints, hot- air joints, cylinder-heads, and similar purposes, asbestus has proved itself invaluable, and for these purposes it is spun into yarn or wicking or rope, or made into mill-board. A large quantity is manufactured into a kind of felt, either alone or, in some cases, along with other fibrous material. Much of this asbestus felt is used as a non-conducting covering for steam-pipes. It is made into sections to fit any size of pipe, and into rolls and sheets for large surfaces. It is in use on the war-ships of the United States Navy, and has there and elsewhere been demonstrated to be supe- VOL. XXXTI. 3-i 53o THE POPULAR SCIENCE MONTHLY. rior to hair-felt as a non-conductor. By preventing radiation of heat from steam and hot-air pipes, this felt effects a large saving in fuel and gives dry steam at long distances from the boiler, and, by preventing excessive warmth of the boiler-house, adds much to the comfort of the workmen. The felt also finds application as a sheathing for covering wood-work in positions exposed to heat, and for fire-proofing flooring, shelving, partitions, and the like. As far back as 1850 the Chevalier Aldini of Milan, experi- mented with asbestus, mainly with the object of turning it to account in the manufacture of asbestus cloth, but little success was met with until twenty years later. The unctuous character of the substance and the extreme fineness of the ultimate fiber are obstacles in the way of making asbestus cloth that shall be strongly coherent and not pull asunder easily. These difficulties appear to have been overcome to a great extent, and now in the form of woven fabrics there are many important applications of asbestus. To one of these, in particular, the attention of the public is frequently directed, because of the numerous fatal fires reported in theatres, music-halls, and similar places of entertain- ment. In the great majority of theatre fires the flames begin in the stage curtains or drapery. When these are made of asbestus, of course they are incombustible ; or, if the curtain alone be of asbestus it affords a means of separating the stage from the body of the theatre, and, in case of fire in the former, prevents its spread to the auditorium. Asbestus curtains are now in use in the principal Roman theatres, and in many theatres in German, English, and American cities, much to the advantage of the theatre-going public. The mineral is also made into gloves, stockings, and other garments ; in fact, complete suits of asbestus clothing can be obtained. In Paris the firemen of the city have recently been furnished with entire suits of asbestus cloth, and it is said to be probable that London will soon follow the example of the French capital. In the form of gloves it is of much service to stokers and furnace-men, and as salvage blankets it is of great value. It is announced that mail-bags will, in the near future, be of asbestus. The frequent loss of mail matter by fire, in connection with rail- way accidents, renders it desirable that some incombustible mate- rial be used for this purpose. Much of the lower grade of asbestus is ground up with other materials and made into cement and paint. The former is exten- sively used as a non-conducting covering for boilers and steam- pipes. Being a cement, it can not be readily removed without much labor and loss, so that it is somewhat less convenient than the felt, which, as already mentioned, is used for the same pur- CHR YS ANTHEM VMS. 5 3 1 pose. It is, however, very much cheaper ; and this, in the esti- mation of many, more than compensates for the less convenient form. Certain it is that much more cement than felt is used as a non-conducting covering. The paint finds extensive application ; a layer of it, while not rendering a wooden surface absolutely fire -proof, is yet proof against sparks and slight flames, and thus prevents the spread and increase of many an incipient fire. In the form of rope it is used in the construction of fire-escapes and supports that may have to withstand fire. We have also asbestus paper. As a wall-paper it aids in rendering a building fire-proof. In the form of writing and printing paper it presents a fire-proof paper that may be used in valuable legal and com- mercial documents. Not only does our mineral resist high temperatures, but it is also proof against the action of the majority of chemicals. It therefore forms a very valuable substance for use in filtering apparatus, especially where acid and alkaline liquids which cor- rode ordinary filtering paper and cloth have to be dealt with. As a filtering medium it is used not only in chemical laboratories, but in manufacturing establishments as well. Though the asbestus industry is only in its infancy, many other uses might be mentioned ; but, bearing in mind that it is possible to produce from it fire-proof fabrics of any form or shape, there will readily occur to the mind of the reader many other possible applications of this curious product of Nature's laboratory which has waited so long for an opportunity to minister to the comfort, convenience, and safety of man. CHRYSANTHEMUMS. By JEAN DYBOWSKI. EVERY season has its peculiar flowers. Even in our ex- tremely irregular climate there are few times in the year when we can not have some pretty blossom to admire. The explorations that are made into all the quarters of the globe, with importations that have followed them, have endowed our flora with such a number of varieties that we may say we have only to choose from among them to get the handsomest there are. There are few flowers that do not wear an infinite charm, and very few are those which fail to make an impression with their elegant form and fresh colors. Some among them, however, unite in themselves such combinations of qualities that they are lifted above their fellows, and occupy a place of honor among THE POPULAR SCIENCE MONTHLY. Of these, those that are late in blossoming offer a special interest. Among the plants of this class which the public justly regards with the highest favor are the chrysanthemums. Few plants combine so many desirable qualities as they ; abundance of blossom, richness in coloring, elegance of form, and long dura- tion, are some of their leading qualities. The plant has been known from very ancient times, and the beginning of its cultivation among us dates from several hun- dred years back ; but it was for a long time neglected, and only a few varieties were known, whose small, imperfectly shaped flowers gave no indication of what could be made of them if special attention were given them. Now the varieties are counted by hundreds. Some have been directly imported from China and Japan, but the most of them are of French or English ori- gin. Intelligent sowing and careful selections have given unan- ticipated results ; and several types have been developed which are quite distinct in the form and arrangement of their flower- rays. The flowers are originally of a similar disposition to those of the field daisies. By cultivation they have been made double — that is, all the minute flowers in the center have .been endowed with large corollas like those constituting the white border of the daisy. Then the form of the corolla has varied so as to appear under very distinct types. Sometimes the petals curve upon themselves, so as to form a regular large head, as in what are called the Indian chrysanthemums. Others curve outward and give a more open form to the whole, as in the Chinese chrysan- themums. In others, again, the corollas deviate in every direc- tion, constituting an odd, irregular type, but marked with a spe- cial artistic elegance, as in the Japanese chrysanthemums. Chrysanthemums were formerly regarded as garden plants; they are equally house plants. There are few plants so well adapted to the ornamentation of our dwellings, whether they are treated as cut flowers or pot plants. For bouquets, only the orchis can rival them in lasting qualities. If cut in full bloom and kept in water, they will last two or three weeks ; but the water should be renewed often, and kept pure with charcoal. Bouquets of exceeding elegance can be made of chrysanthemums. The flowers should be cut with as long stems as possible, and placed, after stripping the leaves from the lower ends, in a wide-mouthed vase (Fig. 1). The bouquet then has the appearance of a sheaf in which each flower displays its full beauty, and, by contrast of color and form, heightens the effect of its neighbor. A special business is made of growing flowers for these bouquets. In this cultivation all the flowers except the terminal one are suppressed on every branch, whereby the flower that is left reaches a large CHE Y SAN THEM UMS. 533 Fig. 1. — Bouquet op Chrysanthemums. size. The plants thus treated are cultivated under glass, and co- piously manured in order to give them great vigor. Flowers have been thus produced measur- ing not less than twenty cen- timetres in diameter (Fig. 2). Assiduous care is given to all the details in raising these flowers. The petals are fash- ioned by hand, and are given the desired curvature, and put in determined positions by the aid of ivory pincers. A sin- gle flower thus produced will bring from two to four shil- lings. The effort to produce such exaggerated specimens can, however, not be regarded as a well-directed one. Over- grown flowers lose in beauty, and extreme regularity of shape is obtained at the ex- pense of grace, and of the great charm of the flower, which lies chiefly in an unexpected novelty of form, and the special stamp of originality that gives each blossom an expression of its own. We might as well make them out of paper at once as treat them so that they shall all be alike. The November chrysan- themum exhibitions of the horticultural societies are growing in importnace. The superb plants that are now shown at them are counted by the thousand. The house of Leveque, which obtained the chief prize at a recent exhibition of the National Horticultural Society of France, had six hundred dis- tinct varieties. Europeans are not alone in their admiration of beautiful flowers. Some other people, hav- ing a fine artistic taste, entertain an enthusiasm for them that Fig. 2. — Large Chrysanthemums (reduced). 534 THE POPULAR SCIENCE MONTHLY. rises to a passion. With the Japanese, who love flowers above every other decoration, the chrysanthemum holds the place of honor, and, as the golden chrysanthemum, is the highest national decoration. It is usual with them to name women after flowers, and " Madame Chrysanthemum " is much favored. A custom prevails among them at chrysanthemum-time of covering human Fig. 3. — Japanese Manikins, plastered and dressed in Chrysanthemum Flowers. (From a photograph.) figures with a coating of clay and arranging chrysanthemums upon them, in colors, in imitation of their dress-goods ; these manikins may represent men playing some scene of action (Fig. 3), or women making or offering tea (Fig. 4). The figures are placed on exhibition, and an admission fee is charged for seeing them. Not all chrysanthemums can be cultivated here in the open air. Some of the choicest varieties, true to their Eastern origin, are too tender for our chilly autumns, and need to be sheltered. But they pay well for the attention, by preserving a brighter verdure, and fresher and more brilliant colors. Some effort has been made, by heading in and otherwise trimming the plants, to make them grow into particular shapes, but the practice has not become very extensive. Chrysanthemums thus combine the advantage of blooming in the autumn and late into the winter, and submitting to various trimmings, and assuming diverse aspects. The cultivation of RAINFALL ON THE PLAINS. 535 Fig. 4. — Japanese Manikins, dressed in Chrysanthemums, represented as making Tea.

By STUART 0. HENEY. THE general impression seems to be that the rainfall has in- creased and is increasing on our " plains " because of their settlement and cultivation. It is fancied that, as the population moves westward, augmented precipitation follows, so that there is now sufficient rain where ten or twenty years ago it was too dry. Travelers who ride swiftly across this region in a day find towns and catch glimpses of farming operations where five years ago they saw but a barren waste. They conclude that a marked climatic change has taken place, and infer that it can only be due to the presence of population. They fancy that the cultivation of the land must produce marked hygrometric results. That this is a remarkable fallacy becomes certain when attention is called to the evidence. In the first place, neither history nor science gives any testi- mony to show that the tillage of the soil and the planting of trees 536 THE POPULAR SCIENCE MONTHLY. have any appreciable, to say nothing of a considerable, effect on the climate. Even in irrigated countries only a barely perceptible increase in the rainfall has been discovered. In Spain, France,, and Italy, irrigation is now not only required for farming, but it is more widely practiced than ever before ; yet, if the " rain-belt " theory were correct, these countries would long ago have had sufficient precipitation for successful agriculture. There is. scarcely any rainfall in the valley of the Nile to-day, after centu- ries of cultivation and of annual floods. Our " plains," or arid region, lie east of the Rocky Mountains, and are at least four hundred miles across. Although the pre- cipitation gradually decreases as one proceeds westward from the Missouri River, it is difficult to fix an isohyetal line. But the line is somewhere between one hundred and two hundred miles west of the Missouri, as the flora clearly shows. It seems to have been taken for granted that the plains were treeless and well-nigh grassless because of lack of rain. Whether the absence of trees is ascribable to the pulverulence of their soil, or the germless lacustrine deposit which covers them, or the excess of moisture,. or the fires of the Indians, it is clear that it is not due to rain- lessness, because the dry hill-tops in the midst of the arid region have some trees. In other words, there is no evidence whatever that the precipitation on the plains to-day is any greater than it was fifty or one hundred years ago ; and there is every reason to believe that it is less. But, it is said, the observations west of the Missouri show a material increase in the rainfall. This is not true. In the reports of the Kansas State University and the Kansas State Agricult- ural College we learn that the rainfall for the ten years from 1879 to 1888 is not so great as that of the previous decade. One authority on the subject has recently taken, among other series, the observations at Fort Leavenworth from 1837 to 1883, and,, testing by the proper mathematical processes their variabilities and probabilities, demonstrates that there is no indication what- ever of permanent climatic change. Yet Fort Leavenworth is one hundred and fifty miles east of the eastern line of the dry region. It must appear irrational to any one, after a moment's reflec- tion, that the settlement of five or six thousand people in a county usually twenty-four by thirty-six miles in dimensions, and the tillage of a small part of its area, would so materially increase the rainfall in the brief period of ten or twenty years as to make agri- culture successful and profitable where before it was not possible. Extending these limits to the wide expanse of States does not make the idea any more tenable. Yet on such conditions as these the theory as applied to our plains is based. The reports of RAINFALL ON THE PLAINS. 537 the Nebraska and Kansas Boards of Agriculture will show that, in the territory lying west of the ninety-eighth meridian in those States, the acreage of land actually under cultivation, when com- pared with the whole area of that territory, is almost insignifi- cant. The climate, as well as the law, pays no heed to small things. It would not answer for the advocates of the theory only to claim that precipitation would be augmented somewhere, and not necessarily in the certain region where is found the increase of farmed lands ; for it would then be very reasonable to suppose that the prevailing southwest and west winds of the plains would drive from them the moisture which the farmer there had earned. Iowa, Missouri, and eastern Kansas, instead of the dry region, would get the increased rainfall. Prof. Frank H. Snow, of the Kansas State University, said several years ago : " But the fact that thousands of new-comers, from ignorance of the climate, have attempted to introduce ordi- nary agricultural operations upon the so-called plains, and have disastrously failed in the attempt, has placed an undeserved stigma upon the good name of Kansas in many far-distant com- munities, and has undoubtedly somewhat retarded immigration during the past few years. It is time for the general recognition of the fact that, except in the exceedingly limited area where irri- gation is possible, the western third of Kansas is beyond the limit of successful agriculture." The severe seasons of drought which have occurred since the above conservative statement was written show the whole truth of the matter to be that the westward ad- vancing line of settlement is by no means an isohyetal one, but that it is merely a line representing in a way the overflow of the population of our Eastern States. It needs but a slight acquaint- ance among the old settlers in central Kansas to know that they fear nowadays excessively dry weather as much as they did twenty-five years ago. The people who live farther west are losing faith in the idea of an increased rainfall, as is evidenced by the fact that over two hundred linear miles of main canals have lately been constructed for irrigation purposes nearly as far east as Kinsley, in the Arkansas Valley of western Kansas. In the Platte "Valley, in Nebraska, large irrigating systems are at present being projected. He who would provide the plains with an ample precipita- tion must remove the Rocky Mountains. Is it reasonable to sup- pose that three or four telegraph lines, small bunches of stripling trees here and there, and the turning over of a few thousand acres of sod, can be of any avail in changing a great dry territory into a garden ? Can man so easily control Nature and her laws ? Certainly not. Climates are immutable so far as the puny efforts 538 THE POPULAR SCIENCE MONTHLY. of humanity are concerned. And it is a grave fallacy, for on the strength of it hundreds of families are induced each year to locate on the plains with the expectation of farming success- fully. Failure follows, of course, and their only hope is to sell out to trustful new-comers, and move where the natural condi- tions are favorable to agriculture and the prosperity of farm- homes. ♦«» LONG FASTINGS AND STARVATION. Bt M. CHARLES KICHET. WHAT takes place in an animal deprived of food may be explained by recurrence to the comparison between the animal and the machine, which, though very old and common- place, is still exact and almost inevitable. In the machine, the burning of carbon gives rise to heat and force ; animals also, burn- ing carbon, develop heat and force. The same is true of plants, for they likewise disengage heat and force ; only the plant disengages very little, and the animal much of them. While the plant is stationary, fixed to the ground, the animal is forced to move to find food. We might, indeed, say that all its wonderfully com- plicated organism is in substance only an apparatus attached to the stomach. The lower animals are hardly anything else than a stomach adapted to motion; and the animal is improved as its means of seeking food everywhere and at a distance are perfected. The animal goes out in search of food because it feels a want — hunger. Nature, in fact, distrusts the intelligence of her chil- dren, and for that reason has given to all living beings instincts and wants ; and has armed them all, without exception, with the sensation of hunger, to provoke them to seek nourishment. With- out this irresistible feeling no being could live. The sensation of hunger is a painful feeling of uneasiness and weakness. It is a general feeling, but is localized apparently in the stomach. Many ancient authors regarded it as a local sensa- tion. Some said that the gastric fluid became more acid and produced a burning feeling in the stomach ; others, that a con- traction of the stomach took place. But, although the sensation of hunger is related to the stomach, it is really general. While it is sometimes alleviated by swallowing earth and stones, such inert substances may deceive it, but do not appease it. It has, moreover, been experimentally determined that the feeling of hunger is not abolished after cutting the pneumogastric or sen- sitive nerve of the stomach. So, in thirst we feel a dryness in the back part of the throat. The local sensation is deceptive, for thirst does not depend upon LONG FASTINGS AND STARVATION. 539 ■ any condition of the mucus of the pharynx. It is caused by the exhaustion of the watery elements of the blood. It is therefore removable by injections of water, and by bathing, when water is absorbed by the pores. If hunger is not satisfied, it disappears after a certain length of time. The most intense suffering is endured during the first twenty-four hours, after which the pain diminishes. The char- acteristic phenomenon exhibited by an animal subjected to star- vation is the constant diminution of weight. I have made many experiments on this loss, comparing animals of various sizes, and have determined that the function of dehydration — or reduc- tion of weight — is in direct relation with the size of the animal ; and I believe that I can deduce a great rule of comparative physiology that the activity and intensity of all the functions are determined by size. Carnivorous animals appear to bear fasting better than herbivorous kinds. The latter eat nearly all the time, and are ill when they have to stop ; but carnivorous animals, in the wild state, are often forced to endure abstentions of consider- able length ; and a fast of several days is almost a physiological condition with them. When we examine the phases of the loss of weight of a starv- ing animal, we find that it loses much during the first days. Then a moderate drain sets in. Again, in the last days considerable loss takes place, and this is the forerunner of death. Cold-blooded animals can support inanition during a prodi- giously long time. M. Vaillant has told me of a python weighing seventy kilogrammes that lived twenty-three months without eating ; M. Colin, of a rattlesnake that lived twenty-nine months. Redi mentions a tortoise that lived eighteen months, and a frog sixteen months, without food. When we have frogs in our aquariums waiting to be experimented upon, we never feed them and they never starve. Dogs can endure abstinence, on the aver- age, of thirty days ; cold-blooded animals, twice as long. They are capable of this, because their tissues are consumed more slowly, and do not require so frequent renewing. With both classes the fatal limit is reached when the loss of weight amounts to forty per cent. This point is reached by the warm-blooded animal ten times as quickly as by the cold-blooded one, because its nervous system is ten times as active. The relation of the nervous system to the intensity of the chemical exchanges of vital action is shown by the existence of hibernating animals, or warm-blooded animals which periodically become cold-blooded. Becoming torpid at the approach of the cold season, their breath- ing and circulation become slow, their motions weaker, their eyelids close, they fall into their winter sleep, and their tempera- ture descends to about 40° Fahr. 54o THE POPULAR SCIENCE MONTHLY. The nervous system is the great inciter of nutrition : when it is vigorous or excited, the digestion is active, the breathing rapid, and the temperature high ; and the loss of weight and the possible duration of abstinence follow the same rule. Man is subject to the same conditions in case of fasting or starvation as warm-blooded animals ; and the influences of size, age, and nervous constitution are similar upon him. This is illustrated, in respect to age, in the legend of the family of Ugolin, in which the youngest child died first, at eight years of age, and the other children followed, while the father did not die till three or four days after the death of the last of them. So, in the wreck of the Medusa, the children died first on the raft, the old men next, and the adults last. We might have supposed that the old men would have resisted better ; but while they may, perhaps, bear moderate fasting with less inconvenience than more active persons, they are less able to endure starvation. New-born infants are less capable of resistance ' than adults ; but the young of animals — puppies and kittens — are more hardy than we would be ready to suppose. Experiments on new-born children have shown that they can offer considerable resistance to external influences, provided they are well fed. Their mor- tality is principally due to a deficiency of alimentation called athrepsy, infants dying of which present the same lesions as starved animals. Their fat is exhausted, while the weight of their nervous system is not reduced. Another feature of the starvation of infants is a relative increase in the globules of the blood by dehydration ; not that the number of globules is greater, but the proportion of them to the whole volume, a considerable portion of the water having disappeared. The duration of the possible fast is considerably influenced by fever. That is supposed to determine the production of poisons which stimulate the nervous system and intensify the process of denutrition ; so that under its influence, as has been observed in experiments on animals and in man, the weight diminishes more rapidly than under starvation alone. The influence of drinking is also noticeable. Of two dogs ob- served by M. Laborde, one died in twenty days ; the other, which could drink at will, was still living at the end of thirty-seven days. There are also examples on the other side. Falck's dog went sixty -one days without drinking or eating. Starving dogs usually drink but little, as if warned by instinct not to drink more than they have to. Water, in fact, expedites the wasting of the tissues and accelerates the drain of the salts in the organism. Hence, by drinking, we excrete more chloride of sodium, phos- phates, urea, etc., so that, although in general animals deprived of water do not live as long as those which can drink, there is LONG FASTINGS AND STARVATION. 541 some difference between those which can drink a little and those which drink a great deal. The last die sooner. There is always less suffering when it is possible to drink ; for it is a characteristic of privation that thirst torments more than hunger, and those who have told of what they have suffered on such occasions have usually emphasized this fact. But I do not believe that the hour of death is much delayed by the ingestion of drinks. In considering cases of fasts endured by men, we have to dis- tinguish between the experimental fast, carefully arranged for and limited to a certain number of days ; the fast which I call cliarlatanish ; and the compulsory fast, which is inflicted upon persons who have been surprised by accidents, such as ship- wrecks or land-slides, or who have been left in the wastes of the desert. Experimental Fasts. — Mr. Ranke, a German physiologist, felt no great inconvenience for forty-eight hours, and his worst sufferings were in the earlier stage. His symptoms were great muscular weakness, impossibility of sustaining prolonged move- ments, fibrillary shiverings, and headache. The most striking phenomena were insomnia with nightmare and throbbing in the head. Beginning nineteen hours after he had taken his last food, he determined by experiment what was his daily diminution of weight, and the rate of consumption of carbon and nitrogen per kilogramme and per hour. He found that the consumption of carbon was twenty times that of nitrogen ; that he lost in weight about 1*2 gramme per kilogramme per hour; and that he pro- duced fourteen litres of carbonic acid per kilogramme per hour. The last number is important. In the normal condition we pro- duce eighteen litres of carbonic acid per kilogramme and per hour. As Mr. Ranke's case was not one of illness or any kind of weakness, the question arises as to the purpose served by these four litres of surplus carbonic acid. The most obvious answer is that they are a luxury. In some experiments which I made, the rate of production by my subject, while fourteen litres during the fast, rose by one third after he had eaten a hearty meal, and his respiration increased in a like proportion. In the cases of the celebrated fasters Tanner, Succi, and Mer- latti, while it may be hard to prove that there was no fraud, the precautions taken against it seem to have been ample to make it extremely improbable. They, moreover, all endured their fasts under special conditions. Merlatti ate a fat goose, bones and all, before beginning ; Succi took a drink to which he attached great importance. The diminution of weight was less considerable than in the other subjects mentioned, but in Merlatti's case the whole amounted to twenty-seven per cent at the end of the fifty days, 542 THE POPULAR SCIENCE MONTHLY. and there was great danger of a fatal result from the enfeeble- ment of the nervous system. The faster persisted in going on to the end, after being advised to discontinue the experiment, and vomited immediately after taking the first food. Nevertheless, he presided at a banquet given in his honor, and fully recovered in two months. Cetti, whom M. Senator put on an experimental fast of ten days, and who drank all the water he wanted, lost more weight during the first than during the second five days. In view of other facts showing less capacity to endure long fasts, we have to conclude that such persons as Tanner, Succi, and Merlatti performed their experiments under exceptionally favor- able conditions. They had no severe weather to face, no concern about their fate, and knew that they had only to make a sign to have a savory repast brought to them. Quite different is the situ- ation of persons who have been buried, for example, under land- slides. Cut off from the rest of the world, they know that no help can come to them for the moment, but that to reach them tunnels must be bored and large masses of earth and stones removed. Long privations of food have often to be suffered under such con- ditions. Berard mentions men who were confined for fourteen days in a damp cellar. Licetus was shut up for seven days. The miners of Bois Mousil were confined for eight days after a land- slide, without suffering greatly. Other examples are afforded by shipwrecked persons. There is an interesting story of a party wandering on the ice-fields who were exposed to a terrible cold for seventeen days, in 1809, with- out other nourishment than water thawed from sea-ice. When found, their skin was sticking to their bones, their eyes were sunk deep in their orbits, and they had fetid breaths and earthy com- plexions, their skin was covered with a sooty scurf, and their tongues were black. This sooty aspect of the skin is a common symptom in great famines, such as occur in India and China. We have many instances of individual fasts. An Italian seventy-seven years old, mentioned by MM. Monin and Mare'chal, lived without food to the thirty-seventh day, only drinking oc- casionally a little brandy and water ; then went to eating again without feeling any inconvenience. A man named Granie, con- demned to execution, starved himself to death in sixty-three days. Antonio Viterbi, in 1821, allowed himself to die of hunger in order to escape the penalty of death. He had also resolved not to drink ; but at one time, taking water in his mouth to refresh him- self, he could not restrain himself and swallowed it. He had vertigo and nightmare, but suffered most from thirst, and died on the seventeenth day. This period, from seventeen to twenty days, represents the mean duration of life of a man in normal conditions who is starving. But Simon Goulart tells of one LONG FASTINGS AND STARVATION. 543 Hasselt who was found alive after having been shut up for forty days without food. Succi and Merlatti were perhaps insane or melancholy. Per- sons who are taken in good health resist less effectively than ma- niacs. M. Lepine cites the case of a girl who had constriction of the oesophagus, who died after having lived sixteen days without food or drink. There is also the extremely interesting case of a German merchant who, having been unfortunate, went into the woods to starve himself to death, and died after eighteen days. He was still breathing when discovered. He had noted down his impressions daily. After five days he wrote : " If I only had fire, a little fire ! How long the nights are — how cold they are ! " On that day he drank. Three days afterward, cold water which he tried to drink made him vomit. A week after that he tried to go to the water, but his strength failed him and he stuck to his resting-place. During these eighteen days of suffering he therefore drank only once. These periods of nineteen, seven- teen, and sixteen days, in persons not out of their minds, justify the estimate of twenty days as the length of the fast which will bring death to healthy persons under no nervous waste. But the time admits of a considerable extension among insane persons and those who have made preparations for their fast. Succi, who fasted thirty days, had been twice in an insane asylum. Cardan relates the case of a Scotchman who lived thirty days in a prison without eating. Devilliers, in the " Journal de Me'decine," men- tions an insane person who died after seventy-five days of partial fasting, in which he took only a few glasses of liquid— a little wine and bouillon. The amount of weight lost at death can not be closely determined, but may be estimated at about thirty per cent. These conditions relate to sound or nearly sound persons. Respecting the stories told of diseased persons, we have to steer between a Scylla and a Charybdis of excessive credulity and ex- cessive incredulity. A Prof. Licetus, of Padua, near the beginning of the seventeenth century, wrote a rather stupid folio in Latin, " On those who can live a Long Time without Food." It contains various chapters, on " those who live eight days " ; " those who live a month " ; " those who lived three months " ; " those who lived from one year to eight years " ; " those who lived more than twelve years " ; and ends with the story of the seven sleepers of Ephesus, who went to sleep in the reign of the Emperor Decius and woke in that of Theodosius. We can more than doubt some of the stories of Licetus ; but there are facts as remarkable as some of them, concerning long fasts by diseased infants and girls, which we can not question. The excessively long fasts, whether experienced by men, 544 THE POPULAR SCIENCE MONTHLY. women, or children, have usually been observed in hysterical persons — for it is now known that hysteria exists in men and children as well as in women. Taking up almost any of the numerous stories related by the old authors, we find manifest traces of hysteria in them. Here, for example, is "the memora- ble and prodigious history of a girl who for many years neither ate nor slept nor voided, and yet lived by God's admirable grace and virtue" (Frankfort, 1587). She was Catherine Binder, of Heidelberg, who at twenty-seven years of age all at once lost the taste for warm food (a hysterical fancy), and ate nothing warm for five years, when she was treated by a quack, and also lost the taste for cold food. She neither ate nor drank for seven years. While we may entertain some question respecting the accuracy of this affirmation, there is no doubt that the girl was nervously affected. She had been deprived of hearing and speech for three years ; she had spasms when she tried to eat, so that she could not swallow ; and, during two weeks that she was watched, she neither ate nor drank. Another girl (1586), religiously affected in her hysteria, was taken with an aversion to everything eatable, and a difficulty in swallowing, and lived for four years on nothing but water and, at long intervals, a little bread dipped in water. Apol- lonia Schrierer, of Berne (1G04), lay physically insensible but wide awake day and night. She was kept apart from her mother and constantly watched by the officers for two weeks, during which she took no food. In the same book with this story is that of a girl of Spires, watched for twelve days, who was assumed to have lived for three years upon nothing but a few drops of water or wine, which she took in her lips. She was twelve years old, and slept most of the time. A girl of Cologne, who lived four years without food, fainted whenever they tried to put anything into her mouth. Passing over several other cases related by these old authors, which vary but little in their general features, we come to a number of cases recorded in medical publications of the eighteenth century, in all or nearly all of which the long fast is accompanied by some kind of disorder of the body or mind. In many of these instances, as in some of those described above, the fast was not absolute, but was occasionally relieved by the introduction of a few drops of milk or broth. Such a fast can be continued indefinitely — as in the case of a woman described by Vandermonde in 1760, who lived thus for twenty-six years. The present century furnishes numerous fairly well authenti- cated instances of extraordinarily long fasts, which were nearly always associated with some form of hysteria. We can not men- tion them all here, and omit those which are most frequently cited in the medical books. Anna Garbero is described by Ricci as having, after a sleep without eating of forty days, been taken, LONG FASTINGS AND STARVATION. 545 on the 8tli of September, 1825, with an absolute repulsion against food, and thus continued till the day of her death, after a lethargic sleep of three months, on the 19th of March, 1828. The autopsy disclosed a contraction of the sigmoid flexure of the colon. One of the most extraordinary cases on record is that of the Dutch hysteric Angelina de Vlies, forty-one years old, who continued without food from the 10th of March, 1822, to 1826. She was sub- ject to cramps and tremors, and was very weak, and not able to rise without help. Bourneville and D'Olier tell of an idiotic child who at two years of age lived three weeks, and at seven years twenty-eight days, on nothing but water and broth. In many similar cases, the patients have eaten occasionally, but only the minimum quantity indispensable for the maintenance of life. Thus, a woman cited by Lase'gue only ate during a year what an ordinary person would require for two days. One of the characteristics of cases of this kind is the extraor- dinary perversion of appetite. An insatiable craving prevails in some of the patients, a loathing in others. Perversions of the sexual passion have also been remarked. "With these fantastic tastes is associated an exceptionally strong and enduring power of resistance. There was for a long time at the Salpetriere a woman named Etchverry, who had hemiplegia on one side and contracture on the other. Her hysteria should apparently have provoked a general denutrition, but it did not. She would not eat, and had to be fed artificially. Her excretions were marked by an extreme deficiency of urea. There was no deception in her case, for she was under constant watch. I have observed in a very precise experiment the diminution in the phenomena of nutrition in hysterics. M. Hannot and my- self, studying two hystero-epileptic cases at the Salpetriere, found that the patient in a condition of lethargy received only four litres of air into her lungs in sixteen minutes, and made only eight in- spirations in thirty-six minutes. This marvelous slackening of the respiratory phenomena constitutes a real hibernation in man, resulting from the absence of stimulation of the nervous system. Observations have been made of a disease of somnolence. M. Charcot has recently published an account of a case, and MM. Semelaigne and Gelineau have published another. An irresistible torpor takes possession of the patients, who fall into a sleep in which all the phenomena of nutrition are slackened, but the sleep- ers wake occasionally and take food or perform physical offices. The fakirs of India, who allow themselves to be buried alive, belong to the same category. They submit to extraordinary mor- tifications, eat but little, abstain from meats, and use curious arts to empty their stomachs. Having hypnotized themselves, they vol. xxxvi. — 35 546 THE POPULAR SCIENCE MONTHLY. rest almost without breathing. While much of this may be im- posture, there are, according to Rousselet and Jacolliot, some well- authenticated cases of the kind. English sentinels were set around one fakir who was buried alive. When disinterred he was apparently dead, but was aroused and lived. I do not consider it necessary to question the correctness of the cases of lethargy and apparent death recorded in the books. A considerable depression of the nervous system accompanies all such phenomena, and the activity of the heart and the rhythm of respiration disappear at a certain stage of the disease. There have not been many experiments on this subject made upon men. We have one, however, from M. Debove, on the influ- ence of suggestion upon hysterics. On his indication to two patients that they should not eat or drink, they comfortably sup- ported a fast of fifteen days, with only slightly proportionate de- crease of weight, and they had had hardly any feeling of hunger at the end of the period. For comparison, M. Debove tried to im- pose a fast on a vigorous man, but was obliged to suspend it after five days. This subject lost at the rate of 0'8 gramme per kilo- gramme per hour, against 0'13 gramme in the hysterical patients. He was not susceptible to suggestion. We draw from these facts that the functional exchanges are retarded in cases of hysteria. We do not yet know the exact influ- ence of the nervous system. There is certainly a diminution of chemical activity in the tissues which produce heat and in the glands that furnish the secretions. This is not saying much, but it is something. — Translated for the Popular Science Monthly from the Revue Scientifique. -♦♦♦- SKETCH OF JAMES GLAISHER, F. R. S. METEOROLOGY owes to Mr. Glaisher the results of many years of patient labor at the institutions and observatories with which he has been connected ; a series of valuable researches undertaken at the instance of the British Association ; and those daring and brilliant observations in a balloon at very great heights in the atmosphere with which his name is most con- spicuously associated. Yet, as has been observed by one of his biographers, " his numerous contributions to scientific and popu- lar literature, often published in a most unobtrusive manner, which is very characteristic of the man, have scarcely gained him so wide a reputation in the learned world as he certainly de- served." James Glaisher was born, according to the " Men of the Time/' in London in 1809. In 1829, as assistant in the principal trian- SKETCH OF JAMES GLAISHER, F. R. S. 547 gulation of the ordnance survey in Ireland, he was charged with the meteorological observations on the Bencorr and Keeper Mountains. These observations were published in 1836. From 1833 to 1836 he was assistant at the Madingly Observatory, near Cambridge ; was appointed in the latter year assistant in the astronomical department of the Greenwich Observatory ; and was made in 1840 Superintendent of the Magnetical and Meteorologi- cal Departments of the same institution, where he remained till he retired from the public service at the end of 1874. In 1865, upon the death of Admiral Fitzroy, he was appointed to the con- trol of the meteorological department of the Board of Trade. From 1841 till very recently he has contributed to the registrar- general's reports the quarterly and annual meteorological re- ports embodying the results of the reductions and discussions of the observations of about sixty voluntary observers scattered over England. Among Mr. Glaisher's earlier contributions to the literature of meteorology were the " Hygrometrical Tables/' first published in 1845, which has passed through six editions, and is regarded as a fundamental work in connection with the science ; " A Memoir on the Radiation of Heat from Various Substances," 1848 ; certain papers on the forms of snow-crystals, 1855 ; a report on the " Me- teorology of London during the Cholera Epidemic of 1853-'54," published by the Board of Health in 1855 ; and a report on the " Meteorology of India in Relation to the Health of the Troops," 1863, which formed an appendix to the report of a Royal Com- mission on the Army in India. In 1857 he conducted the experi- ments and wrote the report of the Royal Commission on the Warming and Ventilation of Dwellings. He was the founder of the Royal Meteorological Society, of which he was the secre- tary for nearly twenty years, and the president in 1867-'68. He is a past President of the Royal Microscopical Society. As a member of the British Association he has been active in the meteorological researches undertaken under the direction of that body ; and we find his name attached year after year to the reports on " Luminous Meteors," " Rainfall," " Rate of Increase of Underground Temperature downward," "Circulation of Under- ground Waters as related to the Water-Supply of certain Towns and Districts," and " Mathematical Tables." The reports on " Lu- minous Meteors " were particularly minute and exhaustive. They seem to have been intended to include as full and accurate accounts as it was possible to get of every meteor that fell any- where on the earth within the view of a man intelligent enough to describe it ; and they embody frequent suggestions as to the direction which future research might take. Thus, the report of 1874 noticed the apparent connection between some meteor-show- 548 THE POPULAR SCIENCE MONTHLY. ers and certain comets, and spoke of the coincidences as being numerous enough, and sufficiently exact to render desirable the further cultivation of cometary astronomy by star-shower obser- vations. The report of 1875 pointed out that the work of properly treating meteor observations had become so great as to be beyond the power of the Association to grapple with it, and commended the arrangements which M. Leverrier was making for that study. In 1878 the committee, finding it probable that the highest attain- able accuracy in mapping the observed directions of the apparent paths of shooting-stars was the real key to the solution of the problem presented by their nightly flights, and that the question of the possible connection of fire-balls and aerolites, or large stony masses, with such showers — and accordingly, it might be, in certain cases, with comets — depended for its solution on ac- curate observations of these meteors, recommended the study as an attractive one, and gave a series of directions for following it up. A committee was appointed at the Aberdeen meeting of the British Association in 1859 to make observations, by means of a balloon, in the higher regions of the atmosphere. Nothing was done for two years, for want of a balloon and an observer. The committee was reappointed at the Manchester meeting in 1861 ; a balloon was contracted for with Mr. Coxwell, an expert aeronaut, and Mr. Glaisher, the most active member of the committee, vol- unteered to go up with him and make the observations. Twenty- eight ascents were made from Wolverhampton, the Crystal Pal- ace, and other places not far from London, between the 17th of July, 1862, and the 26th of May, 1866, of which seven were made into extraordinarily high regions, from 22,884 feet to 37,000 feet, or seven miles. In all these ascents, Mr. Glaisher remarks, in the introduction to " Travels in the Air," " I used the balloon as I found it. The desire which influenced me was to ascend to the higher regions and travel by its means in furtherance of a better knowledge of atmospheric phenomena; neither its management nor its improvement formed a part of my plan." The first ascent was marked by meeting a warm current at a great elevation. Clouds were entered at 4,000 feet, which proved to be also 4,000 feet thick. The temperature at starting being 59° Fahr., fell to 45° at 4,000 feet, and to 26° at 10,000 feet, from which it remained stationary up to 13,000 feet. Then it rose to 31° at 15,500 feet, and 42° at 19,500 feet, after which it fell rapidly to 16° at 26,000 feet. In the ascent of September 1, 1862, the curious phenomenon was observed of the formation of clouds along the course of the Thames from the Nore to Richmond. The clouds followed the river in its courso through all its windings, not departing from it SKETCH OF JAMES GLAISHER, F. R. S. 549 on either side. It being abont the time of high water, the forma- tion was supposed to be the effect of the warm current coming np from the sea. On the 5th of September, 1862, the aeronauts reached the height, which has never been surpassed by man, of 37,000 feet, or seven miles. Mr. Glaisher thus described his experiences after making his observations at 29,000 feet : " Shortly afterward, I laid my arm upon the table, possessed of its full vigor, and, on being desirous of using it, I found it powerless — it must have lost its power momentarily. I tried to move the other arm, and found it powerless also. I then tried to shake myself, and succeeded in shaking my body. I seemed to have no limbs. I then looked at the barometer, and while doing so my head fell over my left shoulder. I struggled and shook my body again, but could not move my arms. I got my head upright, but for an instant only, when it fell on my right shoulder, and then I fell backward, my back resting against the side of the car and my head on its edge ; in this position my eyes were directed toward Mr. Coxwell in the ring. When I shook my body I seemed to have full power over the muscles of the back, and considerable power over those of the neck, but none over either my arms or my legs ; now, in fact, I seemed to have none. As in the case of the arms, all muscular power was lost in an instant from my back and neck. I dimly saw Mr. Coxwell in the ring, and endeavored to speak, but could not ; when, in an instant, intense black darkness came ; the optic nerve finally lost power suddenly. I was still conscious, with as active a brain as at the present moment while writing this. I thought I had been seized with asphyxia, and that I should expe- rience no more, as death would come unless we speedily de- scended ; other thoughts were entering my mind, when I suddenly become unconscious as in going to sleep. I can not tell anything of the sense of hearing ; the perfect stillness and silence of the regions six miles from the earth (and at this time we were between six and seven miles high) is such that no sound reaches the ear." During this time Mr. Coxwell was in the ring above the car, trying to open the valve. He also lost the use of his hands, and was obliged to seize the cord with his teeth and pull it by dipping his head. Consciousness returned gradually to Mr. Glaisher, and no inconvenience followed the insensibility ; and when the party had landed, no conveyance being available, they were obliged to walk several miles. In the ascent of June 26, 1863, the party passed through layer above layer of clouds to the height of four miles ; in the descent, they passed through a fall of rain, and below it a snow-storm, the flakes of which were composed of spiculse of ice and innumer- able snow-crystals. On reaching the ground the atmosphere was 55o THE POPULAR SCIENCE MONTHLY. thick, misty, and murky, and the afternoon cold, raw, and disa- greeable for a summer's day. The observations made during night ascensions, or those which were continued into the night, on temperatures at different heights, gave results different from the theories previously held on the subject. An increase of the temperature with the height was noticed after sunset. The rate of decline of temperature with ele- vation when near the earth was subject to variation as the sky was clear or cloudy. From an elevation of three miles cirrus clouds were seen apparently as far above the observers as they seem when viewed from the earth, and that under such conditions that it was hard to believe that their presence was due to moist- ure. The audibility of sounds from the earth depended consider- ably on the amount of moisture in the air. The noise of a railway train could be heard in clouds at four miles high, but not when the clouds were far below. The discharge of a gun was heard at 10,000 feet ; the barking of a dog at two miles ; but the shouting of a multitude at not more than 4,000 feet. Many differences in the results of observations were supposed to depend upon atmos- pheric conditions, while these vary with the time of day and the season of the year ; so that a great many observations would be required to determine the true laws. Having followed up one of the observations recorded above with a captive balloon and by other means, Mr. Glaisher declared to the Meteorological Society, in 1870, that the theory that the temperature is always lower at higher elevations is not true. Some noteworthy mental impressions are recorded in Mr. Glaisher's descriptions of his ascents. Writing of his feelings at the height of 23,000 feet, and under the imminent necessity of descending at once, he was surprised "at the extraordinary power which a situation like this calls forth, when it is felt that a few moments only can be devoted to noting down all ap- pearances and all circumstances at these extreme positions ; and if not so rapidly gleaned they are lost forever. In such situa- tions every appearance of the most trivial kind is noticed : the eye seems to become keener, the brain more active, and every sense increased in power to meet the necessities of the case ; and afterward, when time has elapsed, it is wonderful how distinctly at any moment scenes so witnessed can be recalled and made to reappear mentally in all their details so vividly that, had I the power of the painter, I could reproduce them visibly to the eye upon the canvas." A fine description, of which we can quote only a part, is given of the scenery of the upper air : " Above the clouds the balloon occupies the center of a vast, hollow sphere, the lower portion of which is generally cut off by a horizontal plane. This section is in appearance a vast continent, often without intervals SKETCH OF JAMES GLAISHER, F.R.S. 551 or breaks, and separating us completely from the earth. No iso- lated clouds hover above this plane. We seem to be citizens of the sky, separated from the earth by a barrier which seems im- passable. We are free from all apprehension such as may exist when nothing separates us from the earth. We can suppose the laws of gravitation are for a time suspended, and, in the upper world to which we seem now to belong, the silence and quiet are so intense that peace and calm seem to reign alone." The descrip- tions of sky and cloud scenes that follow are very picturesque. Mr. Glaisher was elected a Fellow of the Royal Society in 1849. On the death of Lord Chief -Baron Sir F. Pollock, about 1870, he became the third President of the Photographic Society of Great Britain, an office which he still holds. This society pre- sented to him in 1887 a marble bust of himself, executed under its direction by the sculptor Albert Toft. He was a juror in the class of scientific and philosophical instruments at the Great Exhibitions of 1851 and 1863, and was the reporter of the class in 1851. Mr. Glaisher is the author of more than one hundred books and papers relating to astronomy, meteorology, and the theory of numbers. Some of these have already been mentioned. Among the others are many papers in the " Proceedings of the British Association " relating to his balloon ascensions and the subjects of his special investigations. His best-known work is " Travels in the Air," of which he is joint author, which is composed of the narratives by himself of his own balloon voyages and observa- tions, and accounts by M. Gaston Tissandier and M. de Fonvielle of their experiments in the same line. He edited and compressed the English version of Camille Flammarion's " Atmosphere," per- forming, in addition to the regular labor of such a task, that of reducing the notations of the French system to their equivalents in English units, and replacing French observations and data with English corresponding ones. In 1877 he translated and edited Amede'e Guillemin's " World of Comets." After he retired from the Royal Observatory he devoted himself to the completion of the factor tables, begun by Burckhardt in 1814 and continued by Dace in 1862-'65; Burckhardt published the first three mill- ions, and Dace the seventh, eighth, and ninth millions. The three intervening millions have been calculated by Mr. Glaisher and published, with a full enumeration relating to the whole nine millions, in three quarto volumes. Since 1880 Mr. Glaisher has been chairman of the Executive Committee of the Palestine Ex- ploration Fund. 552 THE POPULAR SCIENCE MONTHLY. CORRESPONDENCE. GRANT ALLEN ON THE WOMAN QUES- TION. Editor Popular Science Monthly : IT is gratifying to know that so able an advocate as Mr. Grant Allen has come forward to champion the cause of the real emancipation of woman, in claiming for her the right to be exempt from the burden of her own support. To meet with success as a bread-winner in these days of severe com- petition requires the best energies of the best years of life — just the time when a mother should be giving the best energies of life to the care of her children. The differ- ence between a well-mothered child and an ill-mothered one, in morals, conduct, intelli- gence, and teachableness, is so great as to warrant the assertion that, next to heredity, a child's home training is the most important factor in the evolution of its character. Na- ture has ordained that for this training it shall look to the mother, and hence it is a self-evident fact that her own education should be such as will best fit her for the task. It is about what constitutes the proper training to this end that opinions differ. The average man thinks that to know how to make pies and sew on buttons is enough, while we " advanced" women believe that a "wise" and " sane " mother should be able to meet the moral and intellectual re- quirements of her children as well as admin- ister to their physical wants. We believe that she should know enough of science to give reasonable answers to her children when they question her about the phenomena of nature, and not to object to the study of bot- any as improper for girls (which I heard a model mother of the good old school do, the other day) because it talks about the ova- ries ! We believe that her literary taste should be sufficiently cultivated for her to take pleasure in reading something above the inane fiction which constitutes the chief intellectual pabulum of the average woman of to-day; and even if she should have a taste for anything so dreadful as the higher mathematics, we see no great harm in her indulging it, if it gives her pleasure to do so ; the worst that can possibly result being to give her children inherited aptitudes in the same direction. Indeed, we see no danger to the established order of the universe in her cultivating intellectual tastes simply for her own pleasure, if she chooses. It is only when a woman has to add the drudgery of bread-winning to the natural duties of her sex that she need be condemned to intellect- ual atrophy. In dealing with this part of the subject, Mr. Grant Allen seems to have lost hisusual clear-headedness when he mistakes the aim of " the woman's movement " for an " en- deavor to put upon the shoulders of women, as a glory and a privilege, the burden of their own support." Now, I feel safe in affirming that there is not one among us, even of the most "advanced," who would not gladly welcome Mr. Allen's ideal civiliza- tion, in which all the labor should be done by men — and we won't even grudge them the cooking and the washing, which I can assure them is labor just as real as buying cotton futures or watering railroad stocks. The " woman's movement " does not aim to force upon women the burden of their own support, but merely to fit them, when that burden is forced upon them, to bear it suc- cessfully. Recognizing, as we do, the fact that, with our advancing civilization, a large and ever-increasing proportion of women must be self-supporting, we believe it is un- just and cruel that they should have to en- gage in the struggle handicapped by igno- rance, hampered by conventional prejudices, and oppressed by political disabilities that deny us a vote even on the whisky question — a subject of such vital importance to us. In disposing of a large proportion of the 700,000 superfluous females of the United Kingdom as "infants, lunatics, sisters of charity, unfortunates, and ladies of eighty," Mr. Allen " explains " his statistics on one side only, and forgets to offset his incapa- bles by at least an equal proportion of in- fants, lunatics, priests, octogenarians, con- victs, drunkards, and other ineligibles of the opposite sex, to say nothing of that vast mass of incompetents who must rank away down below zero as husbands, and have to be supported by their wives or sisters. The existence of these negative quantities on the other side is one of the " deplorable acci- dents " that men are prone to overlook in considering this question, but it is one which enlarges so enormously the number of neces- sarily self-supporting women as to make it an open question whether they do not con- stitute a majority of the sex instead of a minority. Now, I am not arguing that this is right, but it is a deplorable fact all the sauie~; and since we can not force the wicked men to support us, the bravest and strong- est of us (instead of sitting down and crying about it) are claiming the modest right to at least support ourselves — and too often the men who ought to be supporting us into the bargain, or the children whose bread they are spending for whisky. And while we are thus relieving society of its " potential " paupers, can the witty philosopher think of no better return than to consign us, with a stroke of his graceful pen, to everlasting COBRESP ONDENCE. 553 confusion as mere paltry accidents ? Oh fie, Mr. Grant Alien ! One more word, as to the supposed effect of the higher education in deterring girls from marriage. I have been engaged in dis- pensing the higher education to girls for a good many years, and have yet to meet the first one who was the least averse to matri- mony ; on the contrary, to quote from a composition on " Girls," written by a little friend of mine not long ago, " I think it is the nature of girls to have sweethearts, whether they are little or whether they are big." The only influence that education can have in " cornering " the matrimonial mar- ket is by making girls more fastidious, and this is not likely to have any practical effect except in the case of a few ugly girls. While I do not doubt that all women are just as willing to look pretty as they are to get married, the " factors of organic evolution," which have taken the place of our old-fash- ioned " providence," have not improved at all upon its methods, but have dealt so un- fairly with a large proportion of the sex that, when told by Mr. Grant Allen that their first business is to look pretty, they feel very much as that philosopher probably does when blandly requested by the photographer to " assume a pleasant expression." Now, as marriage means survival of the prettiest, rather than survival of the fittest (unless we take a purely masculine view of the case and assume that the prettiest are the fittest), all the matrimonial plums fall into the laps of the pretty girls, and the ugly ones have no chance at all but to take every- body's leavings. Of course, I know it is very unreasonable for an ugly girl to ask for any of the plums out of life's pudding; but then, women will be unreasonable, to the end of time — that is one of the factors of the woman question with which we shall always have to reckon. Moreover, the ugly girl sometimes has the presumption to be exceedingly clever, and feels that she can do much better for herself than marry a scrub- by little clerk on forty dollars a month. Under the old regime, when marriage was the only possible solution for a woman of the problem of life, she had no choice but to take any man she could get; but now she naturally declines to give up a hundred- dollar salary for a fifty-dollar man. I do not pretend to decide the question whether the general good does not demand that she should still be forced to sacrifice her- self in a distasteful marriage, rather than remain single to swell the number of " de- plorable accidents " that so weigh upon Mr. Grant Allen's mind. From a human point of view it is undoubtedly for the gen- eral good that lobsters should be boiled, but we shall hardly get the lobster to look at it in that light. E. F. Andrews. Wesleyan College, Macon, Ga., December 9, 1SS9. DECADENCE OF FAKMING IN ENGLAND. Editor Popular Science Monthly : I was very much interested in " The De- cadence of Farming," which you published in November from the pen of Joel Benton. The picture which he draws of the destruc- tion of the farming interest, both East and West, is a vivid one, and deserves the stud- ied consideration of economists. I do not now say that the statements of facts are over- drawn, that the conclusions drawn are illogi- cal and strained, nor that the condition of affairs, as depicted, can be logically and naturally explained in antagonism to Mr. Benton's conclusions ; nor do I stop to point out, now, the facts which his article con- tains, which, if reasonably interpreted, will nullify his conclusions. My purpose in this letter is to present another picture, not so artistically drawn, it may be, but as true to life, I think, as Mr. Benton's picture. The daily papers of November 30, 18*78, contained a news-telegram from London, dated the 29th. After noticing the condi- tion of trade, the closing of factories, and the reduction of wages, it continued : " Kentish hop-growers say, ' As the general depression of agriculture and commerce is largely caused by the protective tariffs of other countries, the duties on foreign pro- ductions should be revived.' " I do not know the political views of the reporter of that dispatch; but the Associ- ated Press reports are presumed to be non- partisan. The New York correspondent of the Cin- cinnati " Enquirer," under date of Decem- ber 12, 1878, sends to his paper the report of an interview with Mr. Armour, the noted dealer and packer of meats, of Chicago, who had just returned from an extended tour in Great Britain. In the reported interview Mr. Armour said : " The manufacturers are running behind, the tenants can not pay their rents, real estate has shrunk in value and can not be sold at any price. . . . The shrinkage is awful. . . . The hard times," he said, " will end in a dreadful depreciation of real estate." I do not know the politics of Mr. Ar- mour ; the " Enquirer " represents the theory of " free trade." The Chicago " Tribune " of July 8, 1879, reprinted from the New York " Herald " an editorial in regard to English affairs, in which the "Herald" said, "The agricult- ural depression in Great Britain has been felt for a long time very severely by the ten- ant farmers." The " Herald ""then quoted from the " Pall Mall Gazette " that " the prevalent belief as to the severity of the depression existing in English agriculture will be confirmed by figures recently pro- duced before the Devizes Union Assessment Committee." The three papers mentioned in this para- graph represent free-trade ideas. 554 THE POPULAR SCIENCE MONTHLY. The London " Telegraph," of March 26, 1881, as cited by several American journals, said that, according to a correspondent of a provincial contemporary, " the depression in the agricultural districts is fully as great as it was represented by many of the speakers in the debate in the House of Commons on Wednesday. . . . Thousands of acres," it said, " are lying unproductive, because without tenants, in various parts of Eng- land ; and a clergyman, writing from Not- tinghamshire, gives a doleful account of affairs in that district. There seems, he says, to be a better state of things in towns than in the country. Here general bankruptcy seems imminent. Hundreds of farms are to be let and few farmers seem to have any capital left to take them." No reform of more urgent interest could possibly be taken in hand by any ministry than the raising of British agriculture from its present drooping condition. Under date of January 10, 1881, consular clerk Charles F. Thirion, of Liverpool, re- ported to the State Department some facts concerning English agriculture. The com- parisons, when not stated otherwise, are between 1870 and 1879. The report shows a decrease of arable area, 33 per cent ; of corn land, 3'1 per cent; of wheat land, 163 per cent ; of barley land, 138 per cent ; of oat land, 4-4 per cent ; a comparison of 1879 with 1874 shows a decrease in the number of sheep of 1,414,000, a little more than 7 per cent. The Chicago "Tribune" of June 21, 1881, reprinted from the New York " Trib- une " an article upon English estates. In that article the " Saturday Review " is quoted as saying, "A state of things has undoubtedly existed for some time, and still exists, which justly awakens great anxiety for the future of the country, and profound sympathy for the sufferers. ". . . The adver- tisements in the London ' Times ' bear elo- quent testimony to this state of things. Columns are filled with notices of old coun- try residences, broad demesnes, wooded parks, and snug country-houses to be sold. . . . Ninety-five per cent of the small es- tates are mortgaged, often for one third or two thirds of their value." The New York " Tribune " represents protective ideas the other two papers are free-traders. A telegram from "Washington to the St. Louis " Globe-Democrat," dated August 1, 1882, stated that a communication had been received at the State Department from the consul at Liege. As reported by the tele- gram, that communication contained this summary : " In one year, the falling off in English agriculture was 42 per cent ; for six consecutive years it was 20 per cent." The " Globe-Democrat " is recognized as a protective organ of a very conservative type. The Chicago " Inter-Ocean " (protec- tion) of September 27, 1889, reprints this excerpt from the London " World " : " An example of the ruinous depreciation of agri- cultural land in Lincolnshire was recently afforded when a farm with houses and buildings, in the neighborhood of Alford, was offered for sale, and the highest bid was £2,100, although the property cost £6,700 eighteen years ago, and a considerable sum has since been expended in improvements." The same Chicago journal quotes from the London " Times " that " fifty per cent of the dock laborers, including perhaps the perma- nent men, are agricultural laborers in point of origin." The startling likeness of the two pictures must be remarked. The one is fuller, decked off with more rhetoric, than the other, but the essential features are the same : the heavy mortgages ; the deprecia- tion in value to one third of the cost; la- borers abandoning the farms for town and city ; the abandoned (at least uncultivated) lands ; unprofitable farming ; decrease in productions and of sheep. I have given the character of my witnesses, when known. If Mr. Benton had admitted that his principal witness on the wool question, Hon. John E. Russell, was a free-trader and interested in free wool (which I understand to be facts), the value of his " opinion " would be heav- ily discounted. The pertinent question that must arise here is, If the protective tariff of the United States has destroyed the agricultural interests of this nation, did the free-trade policy of Great Britain cause the great depression in the agriculture of that nation ? In other words, does agriculture prosper any more under free trade than under protection ? M. B. C. True. Edgab, Neb., December 1, 1SS9. THE TEST OF INSANITY. Editor Popular Science Monthly : Some parts of the paper by Dr. Sir James Crichton-Browne, in the November number of your journal, are open to serious criti- cism. I refer especially to his remarks "on the insufficiency of the definition or test of insanity laid down by British and Ameri- can courts, and on an amended test which would commend itself to medical experi- ence." It is admitted by the learned writer that the accepted legal test — a knowledge of right and wrong in reference to the criminal act — is satisfactory in most cases ; but he holds that there are certain morbid states of the emotions and will which constitute insanity, although connected with a sound intel- lect. Now, the vast majority of medical men with experience of the insane have no knowledge of such cases. For myself, I have never seen a case of this kind in the examination of several thousand lunatics, and I have never heard of any mark by which these can be distinguished from cases of vice and crime. Dr. Crichton-Browne EDITOR'S TABLE. 555 commends the test of Lord Bramwell, con- tained in the questions : " Could he help it ? Was the lunatic free to choose, or under the duress of disease ? " And there is no doubt that the power of self-control is an essential element in the question of responsibility. We may even admit that " impairment of will or loss of self-control, more or less pro- nounced, is the first, last, and universal ele- ment in insanity." But impairment of will is found in all human beings, the sane and the insane. A heathen poet has confessed: " Video meliora probogue, deteriora sequor." [I perceive the better things, and approve them; I follow the worse.] And a sacred writer declares : " The good that I would, I do not ; but the evil which I would not, that I do." Loss of self-control, then, is not at all peculiar to insanity, and the degree of this loss has no measure in medical science. Plainly, the proposed test is quite without value, and, indeed, is no test at all. Again, it is proposed to make " a con- dition of insanity " the test of responsibility. But the term insanity is so extremely vague and indefinite, even a3 used by medical men and experts, that it is worthless for such a purpose. It is applied to every kind and degree of chronic mental disorder, without reference to the element of responsibility. About fifty years ago a law was enacted by the Legislature of New York in these words : " No act done by a person in a state of in- sanity can be punished as an offense." But Chief-Judge Beardsley (in the Freeman case, 4 Denio, p. 27) held that the natural con- struction of this act " would indeed be a mighty change in the law, and afford abso- lute impunity to every person in an insane state." He refused, therefore, so to con- strue it, and held to the principle of the Eng- lish law, which has ever since been adhered to by our courts. It is plain, indeed, that insanity may ex- ist in a degree calling for medical treatment, and even for confinement in an asylum, without bringing with it irresponsibility for crime. In the case of Speirs, a patient set fire to the Utica Asylum to revenge a wrong done him by the authorities. The act was found to be a sane one, and the lunatic was sentenced to a long term in the State prison. It is safe to say that in most asy- lums there will be found at least ten per cent whose degree of insanity is less than that of the notorious Guiteau. But the jury were able, under the common-law test, to find that Guiteau's motive was a vicious one, and that he had the power to refrain from his crime. So indefinite, however, is the line between sanity and insanity, and so hard to be drawn in cases made still more difficult by passion and prejudice, that the plan of a permanent commission, of lawyers and physicians, to visit those who have escaped punishment on the ground of insanity, and report, from time to time, on their condition, should be com- mended to our Legislature. In this way, perhaps, some light may be thrown on the question of a legal test of insanity, and upon the true value of expert evidence. At pres- ent, in view of the law which forbids a phy- sician to disclose on the witness-stand any information acquired by him in a profes- sional capacity, thus often withholding facts of the utmost importance, the necessity of expert testimony in lunacy cases must be admitted. It remains, however, to define more exactly who are experts, by whom they shall be called, and what questions they shall answer. Upon these points, also, the suggestions of Dr. Crichton-Browne are most practical and valuable. L. A. Tocrteixot, M. D. Utica, N. T., November 30, 18S9. EDITOR'S TABLE. USEFUL IGNORANCE. MR. HERBERT SPENCER, in a well-known essay, has discussed the question, " What knowledge is of most worth ? " It is perhaps time to begin the discussion of the question, "What ignorance is of most value?" There is a story told of the great phi- losopher whom we have just named that, on one occasion, in reply to a question upon some rather minute point of history or archaeology, he expressed a devout thankfulness that he knew nothing whatever about it. The capaci- ty of even the greatest minds is limit- ed; and the man who would make the best use of his powers of memory must exercise a wise discretion as to the things he undertakes or tries to re- member. If any principle in education ought to be clear, it is that there should be no overcrowding in the mind of the pupil, but that each portion of knowledge imparted should have room to define itself, to assume distinctness and to grow. Where there is overcrowding there will be no sense of order and no 556 THE POPULAR SCIENCE MONTHLY. healthy development of ideas. All edu- cators acknowledge this, just as men in general acknowledge the moral law ; but how many of them live up to it ? How many of them are willing to leave in their pupils' minds liberal tracts of ig- norance, acknowledged as such — tracts which might be cultivated, but which are left fallow simply in order that the mental powers may not be overtaxed nor imagination unduly restrained ? We venture to say that the cases are rare in which an effort is not being made to cultivate, as it were, every square inch of mental territory, and call all the strength of the intellect into exercise. Each school or academy must teach so many "branches"; it would never do for one to omit what another has in its curriculum ; and every pupil, if not compelled, is urged to take up just as many subjects as he or she can possibly grapple with. The general, at least the frequent, consequence is — congestion, confusion, enfeebled memory, impaired judgment, lowered intellectual vitality. Better far, in many cases, would it have been if the child, with no education be- yond reading and writing, had lived in a concrete world and picked up, gradu- ally, verifiable notions about real things. There is nothing fortuitous in the fact that so many men, eminent in various departments of life, have had but the most meager " educational advantages" in their youth. It would seem as if the one great " educational advantage " they had was in getting free from so-called education at a very early period and be- taking themselves to the school of act- ive life — a school that leads up to ab- stract truths only through multiplied concrete examples; that leaves ample space in the mind for useful ignorance, and consequently makes all the better provision for useful knowledge. There is much sound philosophy in regard to education abroad in the world to-day. What is needed is, that edu- cators should be as wise in practice as they are in theory. The labor of the gardener, every one knows, consists, to a large extent, in "thinning out" his crops. If a similar process could be practiced on the minds of the young, and if it were practiced, the evils of too copious sowing would not be so great; but, as the method is hardly applicable to intellectual growths, teachers should educate themselves up to the point of sowing sparingly in order that they may reap abundantly. The evil of too thick sowing attains, we believe, greater pro- portions in academies for young ladies than anywhere else. There, nearly ev- erything that is taught to boys enters into the course of instruction, while music and other " accomplishments," together with an extra language or two, are generally superadded. As if this were not enough, a special acquaint- ance with the literature, history, and institutions of the ancient Jews, un- tinged, however, by any touch of " mod- eru criticism," is frequently also insisted on. The effect of all this may be easily imagined — a spindly growth of rootless ideas, habits of intellectual indifference, a medley of incongruous notions in re- gard to ill- apprehended facts; in a word, a seriously injured, if not a fatally ruined, intelligence. The intellectual signs of the times, it should be remembered, are not all favorable. We have such an educational apparatus, for extent and scope at least, as the world never saw before ; but the results — it is not easy to be enthusiastic over the results. Where is the quick- ened sense for evidence that we might have expected to see ? Where the se- riousness of intellectual aim? Where the refinement of popular taste? Cant seems to stalk abroad through the world as potent an enslaver as ever of the minds of men. Credulity is wide-spread. Superstition still occupies its strong- holds and rules over vast multitudes. Faction controls our politics and legis- lation is made a plaything. We have, perhaps, expected too much of educa- tion in the past ; but at least, if we un- EDITOR'S TABLE. 557 derstand its true principles, we should try to apply them. One of the first of these principles is not to teach too much, not to congest the mind, not to overtax its powers. Our effort should be to whet curiosity, awaken a cer- tain variety of interests, develop the natural powers of the mind, and leave room for the imagination to work. It is the spontaneous effort of the mind, not its forced labor, that yields the best results. Hitherto we have been fight- ing ignorance so hard, and have been so afraid of it, that the idea of knowledge in any degree being dangerous has sel- dom occurred to us. But knowledge may be as dangerous as food, if given in wrong quantities and under wrong conditions. "When we realize this as fully as we have heretofore realized the danger of ignorance, a new era in edu- cation will have dawned. INDIVID UALISM. The discussion on the land question in the London " Times," a further in- stallment of which is given in our pres- ent issue, will have, we may hope, one or two good results. It will tend to produce in the public mind a more vivid sense of the difficulty of dealing with the land question on any abstract prin- ciples, and it will help, perhaps, to bring home the lesson that social progress is more a matter of individual improve- ment than of political reconstruction. Mr. Auberon Herbert, in the letter which we print this month, calls at- tention to the fact that the whole drift of Mr. Spencer's philosophy is toward individualism, and suggests that the so- cial dangers of the present time arise precisely from the fatal disposition of men to invoke state action as a remedy for all evils. It is indeed a serious fact that so few of those who seek to catch the public ear lay any emphasis on the need for individual reform, or have anything to say about individual responsibility. Institutions are wrong, laws are wrong, social organization is wrong — all general forces and agencies are wrong; but rarely does any one discover that this or tbat man is wrong. Such a discovery, if made, would per- haps not be thought worth announcing, or perhaps might not be considered safe to announce. It is more popular to abuse institutions at large than to at- tempt to fix the responsibility for their defects; and no prudent orator would think of suggesting to his audience that the true starting-point of reform would be in the habits and dispositions of just such people as themselves. Mr. Frederick Greenwood's letter, published by us last month, furnishes a striking illustration of the readiness with which the principle of personal responsibility is overlooked by even thoughtful writers. Mr. Greenwood reads a lesson to Mr. Spencer for hav- ing, as he considers, put forward certain radical theories as to land tenure with- out sufficient qualification, and so given occasion to men like Mr. Laidler to quote him in support of their revolu- tionary schemes. The true view of the matter, however, is that Mr. Spencer acquitted himself of his duty to society by giving expression to the opinions which, at the time, commended them- selves to his acceptance. He did not force them upon the world, or upon any one. He did not offer them as infallibly inspired ; he gave them simply as the views of Herbert Spencer, guaranteeing nothing, even by implication, save their sincerity. What was the nature, then, of his responsibility in the matter ? "We answer that he staked, to a certain ex- tent, such literary or philosophical repu- tation as he had, at the time, acquired, and made himself a mark for the criti- cism of all who differed from him in opinion. On the other hand, he did not render himself responsible for all who might adopt his views simply because they were his, or for those who, under any circumstances, accepted them with- out sufficient examination, possibly with- 558 THE POPULAR SCIENCE MONTHLY. out possessing the qualifications neces- sary for giving them any examination deserving of the name. Nor did he make himself responsible for the inert- ness of those who, having examined the views in question and found them un- sound, failed to demonstrate the fact to Mr. Spencer himself or to the public. When thirty valuable years, in which certain (let us assume) erroneous specu- lations might have been combated, have been allowed to slip by unimproved, so far as that object is concerned, it seems late in the day to turn round on the au- thor of the speculations and read him a lesson on the responsibilities of a philoso- pher. The true way in which to have enforced his responsibility was to criti- cise his views with the utmost rigor, misrepresenting nothing, but omitting no argument that may fairly tell against them. It should not be forgotten, how- ever, that Mr. Spencer showed a further sense of responsibility in withdrawing from circulation the book in which his speculations on the land question were contained, as soon as he became con- vinced that the views enunciated by him upon that point and upon one or two others discussed in the same volume needed amendment or qualification, and in giving it to be distinctly understood that he no longer held to his former opinions on these matters. It is hard to understand, therefore, how the prin- ciple of personal responsibility could have been more fully recognized, or the duties flowing therefrom more scrupu- lously performed, than they were in this particular case by the eminent author of the "Synthetic Philosophy." More to the purpose would it have been, in our opinion, had Mr. Green- wood dwelt with some force on the responsibility — too little recognized — which rests upon those who pin their faith to the authority of others. This is a thing which is too often done in a most reckless and irresponsible manner, with the result of rendering public opin- ion far less intelligent than it ought to be and might be. A sense of individual re- sponsibility for opinions accepted would lead to a more careful examination of all theories and reasonings; and would, in a multitude of cases, abate the blind confidence with which ill-understood no- tions are now espoused. It is quite true that every one is not able to subject the views of a writer like Mr. Spencer to critical scrutiny ; but those who can not do it should, at least, try to take the right measure of their own powers, and abstain from judgments for which they can not give adequate reasons. Very serious also is the responsibility resting upon those who recognize that an opin- ion which has been given to the world is erroneous. The duty of such persons is to proclaim what they hold to be the truth according to the measure of their opportunities and the urgency of the occasion. Because A has accidentally kindled a conflagration, shall B, who is passing by, and who has water at com- mand, make no effort to arrest the flames? Upon whom, in such a case, does the heavier blame rest — upon the man who, without intending it, has set things on fire, or the man who, rather than take a little trouble, lets the fire gain headway? The doctrine of indi- vidual responsibility is the true leaven that will leaven society; for it comes home to each man and summons him to put the question seriously to himself whether he is making the most and the best of his own powers, whether he is really striving to be an efficient unit in the social body. Thousands, nay mill- ions, to-day are waiting for some super- natural or revolutionary moving of the waters, in order that they may, in a moment, be healed of their infirmities. The doctrine of individualism bids them halt no longer by the pool, but go straightway about their business in a new spirit of duty and self-help. We are glad to welcome the appear- ance of a book which promises to help in this direction, namely, Mr. Words- worth Donisthorpe's " Individualism, a LITERARY NOTICES. 559 System of Politics " — a book which ably vindicates the sufficiency of individual initiative in a vast number of matters that have been laid hold of by the state. The present mania for legislation Mr. Donisthorpe attributes to the inexperi- ence and want of historical knowledge of the classes who now control the suf- frage. Errors which the more thought- ful and instructed members of the com- munity have outgrown still look like truths to the less thoughtful and less instructed. The watchword of the hour is individualism, which simply means personal liberty and personal efficiency carried to their highest point. Let all who believe in this do their utmost to make the truth prevail. LITERARY NOTICES. Christian Theism: Its Claims and Sanc- tions. By D. B. Pubinton, LL. D. New York and London : G. P. Putnam's Sons. Pp. 303. Price, $1.75. The author of this book, who is Pro- fessor of Metaphysics in West Virginia Uni- versity, in presenting his thesis, has had three objects in view, viz. — to construct a progressive argument logical in its method and correct in its general conclusions, and likewise defensible in each individual part and item of it ; to free the subject from or- dinary obscurities and difScultics ; and to present it, " without dodging any of its pro- found problems," in such a clear and simple manner as to commend it to the general reader who is willing to think as he reads. Christian theism being presented as a fact, making positive, bold, radical, uncompro- mising, and universal claims, the author pre- sents as arguments in support of it: Intelli- gence in nature, the eutaxiological argu- ment ; volition in nature, the teleological argument ; the personality of God, or the in- tuitive argument ; the goodness of God, or the historical argument ; the unity of God, or the monistic argument ; and the infinity of God, or the causal argument. As " anti- theistic errors " are combated materialism, pantheism, positivism, and agnosticism. The last system is regarded as " an ingenious combination and modification " of the other three systems, which in its present phase has taken shape and name from Herbert Spen- cer, " the great agnostic of modern times," a study of whose works " produces a pro- found conviction of his depth and patience of thought, his breadth and profundity of scholarship, his fertility of imagination, and his frankness and earnestness of purpose." This system is reviewed in an attempt to show it to be logically self-destructive. A comparison of " Evolution and Christian Theism " leads to the conclusion that most of the objections to the former scheme lie not so much against evolution as against the mechanical form of it. " Nature is not a machine, for it is plastic, progressive, im- provable, while a machine is neither of these. Matter can reveal higher and still higher forms of organism, but can never create them. Matter, motion, and force, without a directive idea, can do nothing toward ex- plaining a rationally developed universe. But why exclude a creative and directive idea ? Let that idea be God. There is not a single fact in nature against the existence of a personal God or the occurrence of an act of creation. There are many facts in favor of both. Why not admit that God made the world and sustains it in being? That admission would not blot out evolution, but would view it as a possible or it may be probable method of God's creative and prov- idential work." The question would then be not " evolution versus creation," but " evo- lution the method of creation." The ques- tion of immortality is also considered. The Land and the Community. By S. W. Thackebat. New York : D. Appleton & Co. Pp. 223. Price, $1. This work bears the indorsement of Henry George, who supplies it with a pref- ace. In its original form it was presented as a thesis to the University of Cambridge for the degree of Doctor of Laws. The essay has been expanded and arranged for reference. It is commended for the fullness and clearness with which the historical and legal aspects of the question have been dwelt upon, the attention given in it to the matter of compensation, and the religious feeling and conservative disposition mani- fested in it throughout. It serves the office, according to Mr. George, of a clear and sim- 560 THE POPULAR SCIENCE MONTHLY. pie exposition of essential principles and important facts, which shall give force and definiteness to the ideas growing out of the doctrine of equality of right to the use of the land, make manifest their conformity with historical experience and religious truth, put them in such a relation that the rec- ognition of common rights in land may strengthen, not weaken, the recognition of individual rights in the products of labor; and supply answers to the arguments urged upon the other side. Mr. Thackeray begins his thesis with a history of land tenure in England, divided into the pre-feudal, feudal, and post-feudal periods, in which the subject is treated with special reference to the rights and interests of the community as distinct from the individual interests involved. The origin of the present system is traced to the acts of 1656 and 1660, "which turned mili- tary tenures into free and common socage." Community rights were trampled upon or ignored under these acts, the custom of making settlements grew up and was recog- nized, and lands before common were in- closed without effective resistance till about half a century ago, when laws were passed restricting the right. The key to the future of land tenure may be found in the exercise of the right of eminent domain, which the author regards as an assertion of the state's ownership and its right to change tenants on condition of the new tenant indemnifying the old one for the damage he may suffer. The right of the community to resume its possession of the land being, as the author believes, shown, a second part of the work is occupied with the questions relating to compensation. The rights of the community may be reasserted and secured by requiring those who occupy or cultivate the land to pay to the community a full equivalent for the special privileges which they thus enjoy — that is, through the appropriation of ground-rents by taxation, and applying the proceeds for the benefit of the whole com- munity. A plan is outlined for effecting the change with the least harshness; and the beneficial effects anticipated from it are enumerated. As to those who may be supposed to be injured by the change — re- duced to landlords — the conclusion is reached that most landlords would lose nothing with- out receiving advantages nearly if not fully compensating them ; while the others, if not relatively as great gainers as other classes of the community, would not be absolute losers. The landlords' claims for compensation are examined and found not good, either in law or equity — in fact, the claim of the commu- nity against them is assumed to be the bet- ter one ; and, finally, they are invited man- fully to accept the situation, and themselves lead in recognizing the justice of the new dispensation. Studies in Pedagogy. By Thomas J. Mor- gan. Boston : Silver, Burdett & Co. Pp. 355. Price, $1.15. The author, Principal of the Rhode Island State Normal School, and before that of normal schools at Potsdam, N. Y., and Peru, Neb., has embodied in this volume the fruits of many years of observation, reading, think- ing, and experience in the exercise of his profession, and makes in offering them " an earnest effort to contribute toward the pro- motion of higher ideals of education and bet- ter methods of teaching." His view of edu- cation in the general sense is a broad one, and embraces all that marks the difference between what a child is by nature at birth and that which he becomes by growth, training, and experience. In this sense, na- ture is embraced as one of the greatest forces of education. In the narrower sense, to the consideration of which this book is chiefly devoted, education is restricted to the effect produced upon the young mind by those who seek purposely to influence it, or the direct influence of teachers and schools. Its most important factor is training, which here signifies such a control exercised by the teacher over the pupil as will lead him so to use his faculties as to secure their completest development ; and which has for its imme- diate end the evolution of power. These faculties may be grouped under the heads of acquiring, understanding, reproducing, using, and expressing knowledge, each of which, again, includes its own several topics and means. More nearly than any other work of the teacher it meets the ideal of educa- tion ; it is an essential preliminary to a suc- cessful work of instruction ; and is the pro- cess that best prepares the student for the active duties of life. The special applica- tions of training discussed are those to the LITERARY NOTICES. 561 senses, the imagination, thinking, the sensi- bilities, language, the will, learning music, the use of books, and "training for free- dom." There must be method in the per- formance of the teacher's work ; hence we have a series of chapters on "Methodology." In " Man and his Method " the principle is enforced that, important as the method may be, the man behind it, who should inspire it, is more so. Method in questioning and in teaching arithmetic is treated with some full- ness. The value and purpose of examina- tions are estimated. "The Ideal School- master " holds up the objective toward which every teacher should strive. " The True Function of a Normal School " is a paper which was awarded the prize of the Ameri- can Institute of Instruction in 1885. "Ad- vice to Young Teachers " embodies the sub- stance of several addresses to graduating classes of the normal school. In them " Independent Thinking " and " Training for Citizenship " are prominent topics. Geology of the Quicksilver Deposits of the Pacific Slope, with an Atlas. By George F. Becker. Washington : Gov- ernment Printing-Office (United States Geological Survey). Pp. 486, with seven Plates. Atlas, 14 sheets. Price, $2. The field work of the investigations re- corded in this volume occupied the most of three seasons, beginning in 1883. There remained to complete the examinations sat- isfactorily the investigation of some impor- tant general problems affecting the whole region. Among these were indications af- forded by the paleontology and structure of a previously undetermined non-conformity existing in the Coast Ranges, These were confirmed. Another investigation related to a possible connection between the forma- tion of ore deposits and the metamorphism of the Mesozoic rocks. A third special in- quiry was directed to determining whether the deposition of cinnabar is still taking place at Sulphur Bank and Steamboat Springs, and, if so, under what conditions the solution and precipitation of cinnabar and the accompanying mineral occur. The author finds that the quicksilver deposits lie along the great axes of disturbance of the world. One of these is on the line of the principal mountain systems of Europe and Asia, and the other coincides with the west- vol. xxxvi. — 36 era ranges of the Cordilleran system of America. The principal mines are at Al- maden in Spain, Idria in Austria, Huan- cavelica in Peru, and those in California. From 1850 to 1886 California supplied nearly half the product of the world, but is not probably destined to maintain the same rank in the future. Quicksilver was first recognized as occurring at the croppings of the new Almaden mine in 1845. But few other minerals occur in considerable quanti- ties with the ore. Among them are pyrite or marcasitc, arsenic and antimony, and sometimes copper ores, while other metal- liferous minerals arc comparatively rare. The principal gangue seems to be silica or carbonates. The cinnabar appears to have been deposited solely in pre-existing open- ings, and never by substitution for rock. The fissure systems, which are always pres- ent, are very irregular, and deposits can not conveniently be classified according to exist- ing systems. All of them seem to have proba- bly been deposited in the same way from hot sulphur springs. At Sulphur Bank cinnabar is now being precipitated from heated waters largely by the action of ammonia ; at Steam- boat Springs it is being deposited without complications from the presence of ammonia. In dealing with the processes by which the ore has been dissolved and precipitated in nature, it has been shown by experiment and analysis that cinnabar unites with sodi- um sulphide in various proportions, forming soluble double sulphides, and that these compounds can exist in such waters as flow from Sulphur Bank and Steamboat Springs, either at ordinary temperatures or above the boiling-point. The quicksilver is probably derived from granitic rocks by the action of heated sulphur waters, which rise through the granite from the foci of volcanic activity below that rock. Coal and the Coal Mines. By Homer Greene. Boston and New York : Houghton, Mifflin & Co. Pp. 246. Price, 75 cents. This is a volume of the attractive " Riv- erside Library for Young People," and is intended to tell readers, in a style free from minute details and technicalities, all that re- lates to coal and to procuring it from the earth. The information has been gained for the most part, the author says, from per- 562 THE POPULAR SCIENCE MONTHLY. sonal experience in the mines ; but little of it comes from books, for the literature of the special subject is meager. Beginning at the beginning, we have a brief reference to the geological record previous to coal. Then the composition of coal is elucidated, the time when it was formed is defined, and the situation of the coal-beds is described. The history as it relates to our own period be- gins with the discovery of coal and its intro- duction into use. The account of the mines includes the way into them, the plan of a typical mine, " the miner at work," the ob- stacles and dangers he has to encounter, and the anthracite breakers. A chapter is given to the bituminous coal mines. The account of " The Boy Workers at the Mines " is of particular interest to the young peo- ple, and the chapter on " Miners and their Wages " to searchers for facts. A Handbook of Obstetrical Nursing. By Anna M. Fcjllerton, M. D. Philadel- phia: P. Blakiston, Son & Co. Pp. 214. Price, $1.25. The great number and variety of the things to be attended to in a case of child- birth, many of which are not so familiar as the matters concerned in the treatment of disease, together with their importance as affecting two lives, make a special manual on this subject highly desirable for the nurse. It would be well, also, for every mother to have read a book of this sort be- fore her confinement, in order that she may understand and co-operate in the efforts of the physician and nurse for her wel- fare, and be protected from the antiquated wisdom and dismal tales of injudicious friends. It would be difficult to make a more comprehensive and practical book than Dr. Fullerton's. It is an outgrowth of the extensive practice of the hospital and the systematic instruction of the nurses' train- ing-school. The teachings which it embodies are chiefly the substance of a series of lect- ures delivered yearly by Dr. Anna E. Broo- mall to the nurse-pupils of the Woman's Hospital of Philadelphia, and they are fol- lowed in the Maternity connected with that hospital. The whole ground from the man- agement of pregnancy to the ailments of early infancy is covered. Directions, suffi- ciently detailed for the use of a trained nurse, are given for the care of the patient immediately before and during labor, for the care of the new-born infant, and the man- agement of the lying-in. The appliances which the nurse will need to use, and the articles of clothing for mother and child, are described, and many of them are figured. The Jenness-Miller reformed garments are indorsed. A short chapter is devoted to the appearance of infants in health and disease. In the chapter on ailments of infancy the couvcuse, or brooder, for keeping premature infants warm, is described and figured. Throughout the volume reference is made easy by printing the subject of each para- graph in the margin. Fossil Fishes and Fossil Plants of the Triassic Rocks of New Jersey and the Connecticut Valley. By John S. New- berry. Washington : Government Print- ing-Office (United States Geological Sur- vey). Pp. 152, with 26 Plates. Price, •1. The Triassic rocks, according to Prof. Newberry, probably furnished the first fos- sils collected on this continent : fishes at Durham and Sunderland, Conn. ; plants at Richmond, Va. ; and the so-called bird-tracks at Turner's Falls, Mass. While the forma- tion has received considerable attention in detail, no systematic collection or thorough study of its fauna or flora as a whole was attempted till about 1880, when Prof. Fon- taine took it up for the fossil plants of the Virginia and North Carolina Mesozoic coal basins. His publication established the parallelism of our new red sandstone with the keuper of Europe. The animal remains were left to be studied, and that work was taken up by Prof. Newberry, with results that are presented in this volume. The special studies are preceded by a geological sketch of the new red sandstone regions of New Jersey and Connecticut, concerning the relations of which to one another there ap- pear to be different opinions. The Triassic rocks are about five thousand feet thick and present some singularities of structure. The materials were probably derived from the adjacent highlands. The rocks are charac- terized by their red color, derived from the oxide of iron, the presence of which proves that they contained but little organic matter when deposited. Their relations to the Triassic beds of the interior and the western LITERARY NOTICES. 563 margin of the continent can hardly be es- tablished without larger collections of fossils from Western localities. The fishes, though so far as yet known representing only six genera and about twenty -five species, are locally very numerous, and are found in many places. The principal sites represented in the volume are Boonton, N. J. ; Durham, Conn. ; and Turner's Falls, Mass. ; while they have also been obtained at Plainfield, Mil- ford, Newark, and near Hoboken, N. J., aud at Middletown, Sudbury, Chicopee, Amherst, and Hadley's Falls, in the Connecticut Val- ley. The several species are described in detail and illustrated by figures apparently of the size of nature. We are glad to learn that the author's collection, which is the largest yet made, is safely deposited in the fire-proof Geological Museum of Columbia College. Ligeros Apuntes sobre el Clima de la Republica Argentina. (Notes on the Climate of the Argentine Republic.) By Gualterio G. Davis, Director of the Argentine Meteorological Office, Buenos Ayres. Pp. 254, with 27 Plates and Charts. The Argentine Meteorological Office was established in 1872, and was organized un- der the direction of Dr. B. A. Gould, whom Mr. Davis succeeded on his retirement after twelve years of service. It has gradually extended its sphere of operations to the most remote parts of the country, and now receives observations of the more important weather phenomena from sixty-six stations, and of rainfall from ninety more. The six volumes of the publications of the office embody the results of observations taken at twenty -six points, with analytical discussions of the data, and deductions of the general laws of atmospheric changes ; and the an- nual reports contain a large part of the re- sults reached in the corresponding years. But a more compact work was needed to embody a summary of these results adapted to practical use ; and the attempt is made to supply this need in the present volume, which is intended to put within reach of the colonist, the farmer, and the doctor such meteorological facts as bear upon their in- dustrial enterprises and hygienic studies. Twenty-one stations are selected as typical of the various climatological conditions that prevail in all parts of the republic. The lines extend from the Atlantic coast to the western points of the country, and from lati- tude 54° 53' in Tierra del Fuego to Salta in latitude 26° 46' 20" ; the altitudes range from 8 metres to 2,845 metres above the level of the sea. To each of these stations is allotted its given space for general de- scription, with tables representing the vari- ous meteorological facts in detail and a graphic chart. The publication thus fur- nishes a summary of the local climates, de- duced from several years' observations of the various districts of which the particular stations are the centers. Monopolies and the People. By Charles W. Baker, C. E. New York : G. P. Putnam's Sons. Pp. 263. Price, $1.25. There is abundant reason for including monopoly among the " Questions of the Day," as is done in this volume. Trusts and monopolies exist, as the author shows at length in a series of chapters, in manufactur- ing, mining, transportation, trade, and labor. There are monopolies constructed directly by those who profit from them, monopolies created by municipal enactments, and mo- nopolies supported by governmental policy. The author next examines the theory of uni- versal competition, after which he states the laws of modern competition. He denies that " the prevalence of monopolies evidences the decay of the nobler aspirations of humanity." He regards them as an outgrowth of the modern conditions of industry, and, while they involve evils, he affirms that "the remedy for the evils of monopoly is not abolition, but control." He then specifies some of these evils, and names also some ameliorating influences. The remedies that have been proposed are based on one or the other of the opposite principles, individu- alism and societism, or communism. Mr. Baker maintains that neither should be adopted wholly, and in his concluding chap- ter advocates the owning of all railroads by the Government, and their operation by cor- porations which should pay a rental for the privilege ; the owning of mines by the States, which should lease them to private parties for operation. Water-works, gas and elec- tric lighting plants, street railways, and simi- lar local enterprises should be owned by the cities in which they are located, and also 564 THE POPULAR SCIENCE MONTHLY. operated by private companies. Mr. Baker does not favor the same procedure in the case of monopolies in trade and manufactur- ing. But he would legalize them, and then force them to let daylight in upon their op- erations and agreements, and apply to them the principle of non-discrimination. Aryan Sun- My f lis the Origin of Religions (Nims & Knight) is the title of a book de- signed to show that the mythology of this great primitive race is the parent of the chief modern religions, just as the race itself is the parent of the peoples who hold these religions. In the Aryan mythology we have the immaculate conception, from which the son of heaven, the sun, is born, at the time of the December solstice. We have the twelve signs of the zodiac as his disciples ; his temptation, persecution, and execution. There is a descent of the sun into hades, when he enters the sign Capricornus and appears to remain three days at his lowest point. The Aryans observed baptism, sac- rifice, and the eucharist, and the doctrines of original sin and the fallen condition of man were not unknown to them. When we come down to the Hindus, who have written religious records, we find the same features and more. So also among the Persians, the Egyptians, the Chinese, the Greeks, the Scandinavians, and the ancient Mexicans. Some of the same ideas are found among other ancient nations of the Old World, and among the American Indians. " Ancestral and other systems of worship," says Mr. Charles Morris, in the introduction which he contributes to the volume, "have influ- enced religious practice and ceremony to a marked extent, but have had much less to do with the growth of dogma than the in- tricate details of the history of the gods, to which the numerous phenomena of nature gave rise. Over religious belief the sun has exercised a dominant influence, and still faintly yet distinguishably shines through the most opaquely obscure of modern theo- logical dogmas." In a paper on Teaching School Children to Think (D. Appleton & Co.), Prof. George B. Newcomb discusses first the question, " What is the capacity and exercise of the mind which is indicated by the terms ' thought ' and ' thinking ' ? " He shows that in the reaction from the old mechanical drill we should avoid going to the opposite extreme of taxing the child's mind beyond its pow- ers. The faculty of thinking is a growth, and needs to be dealt with according to the stage of development it has reached. Ca- pacity to form abstract ideas and reason con- secutively does not come at once ; " yet long before reasoning, strictly so called, is devel- oped, there is rationality, the exercise of in- telligence in unifying the scattered particu- lars of sense ; in correlating facts and light- ing up one fact by another " ; and it is all alive in the child's mind, in the curiosity that asks the reason why. While children dislike remote abstractions, they are capable of general thought and rational connecting, and make crude attempts at rational synthe- sis. The manifestations of these faculties may be watched for and taken advantage of and directed as they appear, and the child thus be led gradually up to the habit of ra- tional thought on every subject. This pre- cept partly furnishes the answer to the au- thor's second question, "In what sense or within what limits, if any, should the devel- opment of thought be a prominent aim in the training of school children ? " A third question, involving the consideration of ways and means for developing rational intelli- gence in the pupil, is too large for treatment in a single paper ; and upon it the author aims only to enunciate broad principles or make helpful suggestions without going into details. In A Ramblei-'s Lease, Mr. Bradford Torrey, one of the most pleasant of our rural essayists, assumes the position of a leasehold tenant of other people's fields and woods to the extent of the aesthetic enjoy- ment and opportunities for the study of life and nature that they afford. He there- fore makes himself at home in them, and keeps company with the trees and flowers and insects and birds ; with some of which he has enjoyed privileges of rarely close association. The present volume contains some of the fruits which he has gathered in these possessions ; seemly and agreeable fruits in every way, and flavored with occa- sional choice grains of wit. In it he intro- duces us to the wild birds which he has be- come so intimate with as to feed them by LITERARY NOTICES. S^S hand ; reports his observations on clima- tology and seasonal phenomena ; draws the lessons to be learned from a ramble in " an old road " ; exalts the man " behind the eye " rather than the eye as the important factor in observation, and the mental atti- tude in " taking a walk " ; and presents studies of mountain scenes, " butterfly psy- chology," and the means by which the par- tridge executes his "drumming." (Hough- ton, Mifflin & Co., $1.25.) The Anatomy of Astrangia Dana, pub- lished in quarto form by the Smithsonian Institution, comprises six lithographs from drawings made by A. Sonrel, under the di- rection of Prof. Agassiz in 1S49, illustrating the structure of that madrepore, the only representative of the family in shallow New England waters, with text explaining the plates by J. Walter Fcwkes. Although there has been a great advance in histological methods since the figures were drawn, it has hardly extended to the minute anatomy of these creatures ; so that the representations are nearly as fresh as if they had been drawn to-day. Whatever may be lacking to bring them up to the present state of knowledge is supplied in Mr. Fewkes's descriptions, which are based on studies of living speci- mens. Studies of the Macrochires, Morphological and otherwise, with the View of indicating their Relationships and defining their Several Positions in the System, by R. W. Shufeldt, M. D., bear upon the comparative anatomy and place of the swifts, whip-poor-wills, and humming-birds. The author had already proposed a separate order for the Trochili, or humming-birds, and is more than ever convinced of the correctness of his scheme. In the present essay he proposes a new group or order — that of Cypseli — for the swifts. This order, were it represented by a circle, would be found just outside the passerine circle, " but tangent to a point in its periphery opposite the swallows. In a monograph on The World's Supply of Fuel, Prof. W J Me Gee describes rock gas and its occurrence ; accounts for its for- mation by the decomposition of the organic matter contained in sediments ; answers in the affirmative the question whether it is still forming, and adds that it will probably continue to form indefinitely, though at a decreasing rate; and predicts that it is destined to be, after the coal has been ex- hausted, the world's unfailing supply of fuel and light. The address of Prof. Charles A. White, aa Vice-President of the Geological Section of the American Association, is devoted to the survey and definition of Tlie North American Mesozoic, particularly of the formation called Triassic. There are doubts about the corre- spondence of this with European forma- tions ; and this and certain other facts give occasion for the expression, with some full- ness, of the opinion that we must not expect to discover a precise correspondence, either in time or character, in the geological history of our own and other continents, or an ex- act identity of formations in them. Hence, with all respect to European classification and names, which may still be used tenta- tively in each of the great divisions of the earth, and with reference to the ultimate establishment of a universal system, it is for North American geologists to elaborate a scheme for the formations of our own con- tinent. In a pair of papers on Meteorites and what they teach us, Dr. H. Hensoldt sum- marizes what has been learned about me- teorites, and declares his own theory as to their origin. This theory is based on the presence of liquid carbonic acid in the cavi- ties of these bodies. The fluid is ascer- tained to be carbonic acid by the instanta- neous change of form which it undergoes between 30° and 31° C, which is character- istic of that substance. Now, carbonic acid can not be liquefied except under a pressure which exists in nature only deep in the earth. Hence the meteorites must have been at some time subjected to such a press- ure. It is therefore concluded that they have come from the interior of some plane- tary body which has been rent by an explo- sion. Proceedings of the Boston Society of Natu- ral History, Vol. XXIV, contains the reports of the society and its proceedings, with the papers read, from May, 1888, to May, 1889. Prof. Hyatt's report as curator of the muse- um shows that that institution is growing at a healthy rate, and the arrangement of its collections is going forward. The papers relate to various topics of biology, geology, 5 66 THE POPULAR SCIENCE MONTHLY. and archaeology. Among thern are those of Prof. Hyatt on the "Evolution of the Fauna of the Lower Lias " ; of Mr. S. H. Scudder on a Palaeozoic " Cockroach Fauna " at Richmond, Ohio; of Prof. Marcou on " Canadian Geological Classification for the Province of Quebec " ; of Mr. Alfred C. Lane on the " Geology of Nahant " ; of Mr. War- ren Upham on " Marine Shells and Frag- ments of Shells in the Till near Boston " ; of Mr. Samuel Garman on the " Evolution of the Rattlesnake " ; and of Prof. Goodall on the " Life and Work of Dr. Asa Gray." Several archaeological papers, which ap- pear in this volume of the " Proceedings," are also published separately by the Peabody Museum of American Archaeology and Eth- nology, under the title of Palceolilhic Man in Eastern and Central America. They are "Early Man in the Delaware Valley," in- cluding an account of the lately discovered " Rock Shelter " at Naaman's Creek, and descriptions of Palaeolithic implements ; and an account of an implement from the In- diana gravel, by Hilborne T. Cresson ; Prof. G. F. Wright's paper on the " Age of the Philadelphia Red Gravel " ; " Water-worn Implements from the Delaware River," by Dr. C. C. Abbott ; and remarks on the whole subject by President F. W. Putnam. Prof. Wright's paper bears upon the age of the rock shelter and of the implements in the Delaware Valley described by Mr. Cresson, which the author decides are older (perhaps by a thousand years) than the deposits at Trenton, N. J., Loveland and Madisonville, Ohio, Little Falls, Minn., and Medora, Ind. (Cresson). An Obsidian Implement from Pleistocene Deposits in Nevada, by WJ Mc Gee, discusses the age of a handsome neolithic work found on Walker River, to which the author has already made reference in the " Monthly " (November, 1888, p. 25). The solution of the question is partly dependent upon the char- acter of the occurrence of the implement — whether it be adventitious or normally in situ. The deposit being unconsolidated, this can not be determined certainly without the help of other human relics found in the same place to keep it company ; and such have not been found. But, since the implement was ob- served, the discovery of other extremely an- cient relics in various parts of the country has given color to the hypothesis that this was an original deposit ; and the author now inclines to that view. The Aborigines of the District of Colum- bia and the Lower Potomac — a symposium in the Anthropological Society of Washing- ton— besides an address by Otis T. Mason, introducing the subject, contains papers on " The Geological Antecedents of Man in the Potomac Valley," by W J McGee ; " The Palaeolithic Period in the District, of Colum- bia," by Thomas Wilson ; " Ancient Village Sites and Aboriginal Workshops," by S. V. Proudfitt ; " The Pottery and Textiles of the Tide- Water Region," by W. H. Holmes; "The Shell Mounds of the Potomac and Micomico," by Elmer R. Reynolds ; " Indian Tribes of the District," by James Mooney ; and a discussion by Prof. F. W. Putnam. Of six additional " Bulletins " of the United States Geological Survey, No. 48 is On the Form and Position of the Sea-Level, with special reference to its dependence on superficial masses symmetrically disposed about a normal to the earth's surface, by Robert Simpson Woodward. The treatise is mathematical, and relates to a problem of peculiar difficulty, the solution of which has been as yet only approached. The same author's Latitudes and Longitudes of Certain Points in Missouri, Kansas, and Neiv Mex- ico, constituting " Bulletin No. 49," relates to the processes of determination at Oswego, Elk Falls, and Fort Scott, Kan. ; Springfield and Bolivar, Mo. ; and Albuquerque, N. M. The author has endeavored to collect, arrange, and discuss the observations in such a man- ner as to render their results most useful for the purposes of geography and geodesy. Bulletin No. 50, also by Mr. Woodward, con- sists of Formulas and Tables to facilitate the Construction of Maps. The tables were pre- pared for the Division of Geography in 1885-86. Constant use since then has demonstrated their utility. They have been revised and extended, and are accompanied by an explanatory text. Dr. Charles A. Wldte gives, in Bulletin No. 51, descriptions of some Invertebrate Fossils from the Pacific Coast. They fall under five headings : " New Mollusca from the Chico-Tejon Series of Cali- fornia," representing nineteen new species and one new genus ; " The Occurrence of Equiv- alents of the Chico-Tejon Series in Oregon LITERARY NOTICES. 567 and Washington Territory " ; " Cretaceous Fossils from Vancouver Island Region," in which an intimate relation is shown with the fauna of the Chico group ; " The Molluscan Fauna of the Puget Group," unique and indi- cating deposition in a large estuary; and " Mesozoic Mollusca from the Southern Coast of the Alaskan Peninsula," which are re- garded as new. No. 52, Subaerial Decay of Bocks and Origin of the Red Color of Cer- tain Formations, relates studies of the sub- ject by Israel Clark Russell, chiefly among the Appalachian Mountains in Virginia and North Carolina. The author believes that changes by decay have' a wider geological bearing than has generally been assigned to them ; and that the red color of certain sandstones is due to a coating of their par- ticles with ferric oxide received during the process of subaerial decay of the rocks of the debris of which they are composed. The last of the present series of Bulletins — No. 53 — is a study of The Geology of Nantucket, by Prof. N. S. Shaler. The island is re- garded, together with the accompanying southern Massachusetts coast, Martha's Vine- yard, Long Island, etc., as " the dissevered remains of a great shelf formed of the debris brought to its present position by the glacial ice and by the streams of water which flowed beneath it." The United States Department of Agri- culture, Division of Entomology, publishes an investigation of The Root-knot Disease of the Peach, Orange, and other Plants in Florida, due to the Work of Anguilhda, made under its direction, in 1888, by Dr. ./. C. Neal. A large number of species of plants are attacked by the worms, whose depredations are marked by the appearance of swellings or " knots " on the roots, and threaten to be damaging. The author has made studies of the nature of the insect and its ravages, and has experi- mented with reference to the remedies. His report is illustrated with plates representing attacked roots and the life-history of the enemy. The June number of the Journal of Mor- phology, Vol. Ill, No. 1 (Prof. C. 0. Whit- man and Edward Phelps Allis, Jr., editors ; Ginn & Co.), contains articles on " The Acti- niaria of the Bahama Islands," by Dr. J. Play- fair McMurrich ; " Contributions to the Com- parative Osteology of the Families of North American Passeres," and " Notes on the Anatomy of Spcotyto cunicularia hypogea^ by Dr. R. W. Shufeldt ; and " Variation of the Spinal Nerves in the Caudal Region of the Domestic Pigeon," by James I. Peck. The September number, Vol. Ill, No. 2, has "The Mechanical Causes of the Develop- ment of the Hard Parts of the Mammalia," by E. D. Cope ; and " The Embryology of Blatta germanica and Doryphora decem- lincata " — the cockroach and the Colorado potato beetle — by William M. Wheeler. A Bibliography of Geodesy was compiled by Prof. J. Howard Gore to supply a need which he felt while preparing a work on the " History of Geodesy." Before proceeding far in that work he found it very difficult at any time to make sure that the literature re- garding the operations of a given period had been exhausted, and he sought to collect titles as well as the works themselves. His purpose extended to making the enterprise useful to others. He went abroad and searched through European libraries, exam- ined minor libraries by proxy, and corre- sponded with authors to find if they had any other works than those of which he had the titles. The outcome of this persevering la- bor is a list filling four hundred columns of references, with short remarks where the title alone is not explanatory enough. Sev- eral institutions, among them the Interna- tional Geodetic Congress of Berlin, offered to publish the book ; but the author thought our Coast and Geodetic Survey was entitled to the preference, and the work is therefore issued under its auspices. Part I of the nineteenth volume of the " Annals of the Observatory of Harvard Col- lege" contains Meteorological Observations made during the Years 1S40 to 1888 inclu- sive, under the direction of the several di- rectors of the observatory, Profs. W. C. and G. P. Bond, Joseph Winlock, and F. C. Pick- ering. Partial publications of these observa- tions could already be found in the " Mem- oirs " of the American Academy of Arts and Sciences, the " American Almanac," and the Patent-Office Reports, but it has seemed desirable to make a collection of the monthly means. The volume begins with a history of the meteorological work of the observa- tory ; the " monthly and annual results " come next ; after which follow " Observa- 568 THE POPULAR SCIENCE MONTHLY. tions of Aurora Borealis," " Thunder and Lightning," and " Miscellaneous Phenome- na," embracing " temperatures of wells," of " river, rain, and cellar," " Extremes of At- mospheric Pressure or Temperature," " So- lar Ilalos and Parhelia," lunar halos, and " General Remarks."— Vol. XX, Part II, of the same series records the Observations made at. the Blue Hill Meteorological Observ- atory, Massachusetts, in 1888, with a state- ment of the local weather predictions, under the direction of A. Lawrence Rotch. A paper on Domestic Economy in Public Education, by Mrs. Ellen H. Richards, of the Massachusetts Institute of Technology, is published in the series of " Educational Monographs " of the New York College for the Training of Teachers. The success of the manual training system that has been developed out of the carpentry classes for boys has prompted the author to look for a kindred course adapted to the life of girls. She finds it in domestic economy, in which the purposes of sanitary science and hygiene should play an important part. A schedule for a four years' course is introduced. In it cooking — "kitchen science" — is promi- nent, and this, the author insists, can be placed on a level with the use of workshop tools as a means of mental and physical training. Having mentioned the scientific principles involved in the processes of pre- paring a meal, the author maintains that " the school-girl who has had the elements of chemistry and physics, which are often taught as abstract sciences, summed up and applied to the making of a simple dish, has had her mind awakened to the relations and interdependence of things as no other train- ing now given can awaken it." In an ap- pendix are given summaries of the provis- ions made for teaching domestic economy in several public schools and colleges in the United States and in the girls' schools of the city of Paris. — Another number of the same series is an essay on Graphic Methods in Teaching, by diaries Barnard, with an in- troduction by Prof. John F. Woodhull, set- ting forth " Training in Natural Science as an Essential Factor in the Education of the Citizen." Mr. Barnard's essay embodies the relation of experiences in training children to the observation of natural facts and phe- nomena, and to keeping regular records of them by means of the graphic system, with specimens of the actual work of certain children in that line. Of the value to the child of thus recording weather observa- tions the author says : " The making of the diagram (printed forms should never be used) is something in the way of mechanical drawing that is a good training for the hand and eye. Secondly, the diagram, being fast- ened upon the wall in some convenient place, becomes a reminder of stated work to be done at a fixed hour — a capital training in punctuality, promptness, and precision." Then the thermometer is a tool which the child learns to use. He is induced to go out of doors. Pride is taken in the work as it goes on, developing a regular course. It is instructive and a useful exercise in neat- ness and accuracy, and when it is done " the child has two graphic statements of real phenomena in nature observed by himself and so recorded that at the end the entire work of the month is plainly seen." The Globe, a New Quarterly Review of World-Literature, Society, Religion, Art, and Politics, of which we have the first number, October to December, 1889, is projected by William Henry Thome, in Chicago, to be a " first-class literary review," which he be- lieves we have not ; and he aspires " to edit and publish something better, broader, stronger, and more cosmopolitan " than any existing American periodical. After a care- ful inspection of his work we are forced to say with regret that he has not reached the object of his aspiration, and that the want he describes, if it existed before, is still un- supplied. The initial number of The Globe contains articles on " The Fuss about Bruno," " The English, French, and American Stage," " The Heroic and Commonplace in Art," " Emerson and his Biographers," " Socialism and Poetic Retribution," " Dr. McCosh and Modern Philosophy," etc. Edenic Diet, the Philosophy of Eating for the Physical and Mental Man (Isaac B. Rumford, Santa Cruz, Cal., 25 cents), is in- tended primarily to exalt an exclusive vege- table diet and furnish recipes involving its principles. To this are added a mass of rhapsodical matter and a scheme for " an Edenic home " which those may enjoy to whose mode of thought they are adapted. Mr. J. Madison Cutts, of Washington, LITERARY NOTICES. 569 has published, as especially pertinent to the times, an address by the late Stephen A. Douglas on An American Continental Com- mercial Union or Alliance. It is, he says, the last paper written by the distinguished statesman, and has not been published be- fore. It was prepared after seven of the Southern States had gone through the form of seceding, and was intended to serve as one of Mr. Douglas's immediate plans to promote the future welfare of the country in case a reconciliation and restoration were effected. Besides its interest as the last thought of one of the most distinguished statesmen of the period before the war, the address is pertinent on account of its di- rect bearing on a scheme of national policy which is now under discussion. In an essay on God and iJie Universe, Mr. James W. Stillman proposes to consider 41 the alleged existence of a Supreme Being and the theistic hypothesis of creation." lie is brought to the conclusion that " the whole problem of the existence of God and the origin of the universe is entirely beyond and above the scope of the human intellect " ; and there he is content to leave the matter. In a pamphlet on The Disposal of the Dead, Dr. John M. Peacocke, of Brooklyn, after considering other methods, suggests desiccation, which was practiced by the an- cient Peruvians, as in many respects the preferable one. Questions for Debate in politics and eco- nomics is the latest publication (No. XXVIII) of the Society for Political Education, 330 Pearl Street, New York. A perusal of its pages shows its compilers to have seized upon every living issue affecting American citizenship. In addition to the questions, subjects for essays are given, as well as terms for definition. Brief and pithy hints to debaters and essay-writers are included, as also a form of constitution and by-liws for debatiug-clubs. Pages 40. Price, 25 cents. PUBLICATIONS RECEIVED.

Pillsbury, of Minneapolis, states that the manufacture of flour is to-day prob- ably the largest industry in the United States, not excepting that of iron. About 85,000,000 barrels of flour, of an average value of about $400,000,000, are made in this country yearly. About ten per cent of this product is manufactured in Minneapolis. As much as 1,000 car-loads of wheat are often re- ceived at Minneapolis in a single day, or enough to load a train six miles long. To say that flour made from Minnesota and Da- kota wheat is the best in the world is only saying what is recognized by the trade the POPULAR MISCELLANY. 571 world over, in the prices which it brings as compared with other flours. Wheat grown in this latitude has so large a proportion of gluten and phosphates that it is gradually but surely crowding more starchy flours to the wall. When Mr. Pillsbury began milling twenty years ago, he secretly brought flour from St. Louis to use in his own family. Minneapolis flour sold very much below that made in other sections of this country, and stood at the foot of the list in market quo- tations. Now it stands at the top of the list. A Board of Trade report, of the city of Minneapolis, for 1866, stated that the production of flour in the city during that year was 172,000 barrels; now it is forty times as much. Only eleven years ago the amount of flour made in Minneapolis and exported from this country was 109,183 bar- rels ; now it is over 3,000,000, or thirty times as much. It is the improvement which has been made in milling in this sec- tion which has accomplished these results. It has also made the rapid settlement of the Northwest possible, as wheat is by all odds the chief crop of that region. On the other hand, the rapid increase of the farming pop- ulation in the tributary country has made possible the rapid increase of mills in Min- neapolis. Another thing that has contrib- uted largely to this result is cheap trans- portation to the East. A few years ago the millers were paying one dollar and a half a barrel to get their flour carried to the sea- board ; now the rate is only fifty-five cents. Mr. Pillsbury deems it quite possible that the flour industry of the Northwest is even yet in its infancy, as probably not more than ten per cent of the available land trib- utary to Minneapolis has been placed under cultivation. Aboriginal Mounds in Manitoba. — The Winnipeg mound region, as described in the American Association, by Prof. George Byles, of Manitoba College, includes a dis- trict some four hundred miles long from east to west, and running from the interna- tional boundary north to at least latitude 50°. The author had seen some sixty mounds and had opened ten, working usually in con- nection with the Manitoba Historical Society. Numerous skeletons have been exhumed. Un- manufactured articles found included large quantities of charcoal — red and yellow ochre and birch bark charred. Manufactured ar- ticles : Stone implements, scrapers, gouges, chisels, axes, malls, conjurers' tubes, and a set of gaming stones. Bones : Breast orna- ments of various kinds, whistles, beads, etc. Shells : Columella of conch from trophies, tropical natica and marginetta shells made into beads, wampum, and breast ornaments. Horn : Fish-spear, pottery, numerous marked fragments, various copper implements, and near one skeleton two lumps of arsenical pyrites, no doubt used as sacred objects. All mounds were circular, and all on promi- nent headlands. The majority contained skeletons, probably of Mandans of the Mis- souri, who fifty years ago were almost ex- terminated by small-pox. Certain mounds, from the state of the bones and certain topo- graphical and geological considerations, are likely to date from the beginning of their central parts four hundred years back. Tapestries. — The word tapestry has pri- mary reference to carpets. As now used, we learn from a lecture by Mr. Alan S. Cole upon the subject, it may be read in two senses : one in which it refers to hangings generally ; and the other in which it implies a special method of producing a textile fab- ric. In making carpet by hand, as in ordi- nary weaving, a stretched warp is necessary ; but the warp-threads play no visible part in the face of the carpet. They are covered with weft-threads. Instead of a shuttle with a weft, as in weaving, various sets of thread are used, which are looped, knotted, and intertwined upon the warp-threads. In making carpets with a pile, the ends of the threads which have been knotted upon the warp are cut. From above these knotted threads, and across and in between the warp- threads, a stout thread is thrown. This is pressed down with a comb, so as to com- pact the whole fabric. A fresh series of knottings is then made, and the previous operations are repeated. In another closely allied process for making carpets and hang- ings, a stout cord is thrown across and in between the warp-threads ; no scissors are used to cut the ends of knotted warp-threads, and no pile is produced. This process re- quires the variously colored wefts to be in- tertwisted between groups of the warp- 572 THE POPULAR SCIENCE MONTHLY. threads ; and in this respect it is almost identical with that particular process which is known as tapestry- making ; but tapestries are finished for display on one side only. They are made upon vertical threads, when they are high-warp or haute lisse, or upon horizontal threads, when they are low-warp or basse lisse, tapestries. But the results of both methods are virtually identical, so that it is almost impossible to detect any pecul- iarity which shall distinguish one from the other. The earlier hangings appear to have been of lighter material than that of the special fabric ; and they were ornamented by weaving, embroidery, or painting. The special process was applied in early times to making small ornamental trimmings for costume. Its application to works on a much larger scale appears to date from the twelfth and thirteenth centuries, although it had probably been already employed in old Asiatic civilizations for carpets. The num- ber of colors of the earlier tapestries was re- stricted, but, after the tapestry-making craft was established, a more generous scheme of colors was employed. This has developed in such a way that it is a boast now at the Gobelins factory that they have upward of fourteen thousand four hundred tons of colors in dyes for threads. Our Arid Regions aud the Rainfall. — The soils of the arid regions of the United States, according to the paper read by Prof. J. R. Dodge at the meeting of the American Association, are generally fertile to excess. The only amelioration they require is that which is secured by the application of water. That may be obtained from natural precipi- tation; by irrigation from supplies at pres- ent available or from storage reservoirs and catch-basins to be erected to hold the sur- plus of rains ; by pumping from the under- ground channels of streams ; or by means of artesian wells. After all available water has been obtained by these means and ex- pedients, there is still a large part of the superficial area that must remain unirrigated. Some say that this part constitutes four fifths or five sixths of the whole, but those who have an intimate knowledge of the practical work of irrigation insist that it is not more than one tenth or one eighth of the area. Still, the remainder is not quite a desert. There are what are called agricultural rain- belts which, with from fifteen to eighteen inches of water, sometimes twenty inches per annum, are found to produce good crops of corn up to an elevation of three thousand or four thousand feet, and wheat, oats, potatoes, alfalfa, and many grasses up to six thousand or seven thousand feet, by adaptation of methods of cultivation to suit the best utili- zation of available moisture. The question of increasing rainfall gains an affirmative answer from practical cultivators, while the records of the rain-gauge fail to make such a response. There is an increase, if not in actual rain, certainly in available moisture ; for the water which formerly flowed away with as much facility as from the back of a duck, is nearly all retained by cultivated lands. If the irrigation is general and con- tinued for years, there is a change of climate, with more moisture in the atmosphere, dews at night frequent where they were formerly unknown, and general enhancement of the agricultural value of the air. The Beanty of Childhood. — A recent dis- covery of classical sculptures has recalled attention to the fact that the ancients had, so far as appears from their works, no ap- preciation of the beauty of childhood. In the present instance, in which the figures relate to death scenes and include family pictures, while the mature characters are represented with the best skill which the artist could command, the children — at the age fullest of beauty for a modern eye — are executed with archaic clumsiness. Miss Har- rison has pointed out, in her lectures on Greek sculpture, that representations of in- fancy are characteristic of the decaying art of Alexandria ; the best period of art affords no specimen of such a choice of subject. " The artists whose work has afforded models for all time have not left a single specimen of that beauty which modern eyes most ad- mire, the beauty of childhood." And in Grecian and Roman literature there is none of that happy picturing, that dwelling with delight upon the beauties of childhood that seem to have entered into the very essence of modern natures. To the Romans, " in- fancy was only a journey toward manhood ; the sooner it was over the better." In the reference to childhood which is most truly POPULAR MISCELLANY 573 affecting of all in ancient literature, the fright of the child in Homer's " Parting of Hector and Andromache," the interest, " if we analyze it, belongs rather to an impartial delineation of human life as it is, than to any sympathy with the helplessness and de- pendence of its earliest stage." While mod- ern art does not show an equal lack of the taste for childhood, it " is comparatively feeble at all times in comparison with the feeling of our own day." This feeling is re- flected in its intensity first in the poem3 of Wordsworth and the pictures of Sir Joshua Reynolds. " This sympathy with childhood," says the writer in the " Spectator " whose essay we have summarized, " which gives its coloring to modern literature and art, is to be traced back to utterances which have in- fluenced more than the literature and art of modern Europe. ' Except ye become as little children, ye can not enter into the kingdom of heaven,' was a saying new to the world. The fresh aspect under which all weakness, all dependence, appeared in the light of that teaching, was evidently bewildering to its hearers." It took centuries for the Chris- tian world to take in the full meaning of that utterance, which has not been realized as a fact of ordinary life till nearly our own time. But now, " for a year or two in this pilgrimage of ours, the most commonplace, the most tiresome of us is invested with this wonderful capacity [of persuasion and con- ciliation] ; every human being has once upon a time hushed enmities and bridged estrange- ment." Iron as a Purifier of Water. — The power of iron to remove coloring matter and or- ganic contamination from impure waters has been made capable, by recent improvements in processes, of receiving a greatly extended application. In Prof. Bischof's system, a sand filter which separates the mechanical impurities is underlaid by a mixture of gravel and iron in the proportion of three parts to one. When the water is drawn off from this filter after using, no discoloration is visible in the upper sand, nor till near the iron mixture. In this the particles of gravel and iron become thickly coated and mixed with the reddish, slimy product of the chemi- cal action of the iron ; and, still lower down, the mixture is black, and not subject to change. The slimy-coated mixture has to be removed and washed every six months. By another improvement the iron is pre- sented in a state of constant agitation, and the slimy coating being washed away as fast as it is formed, an always clean surface is offered to the water. The working of the method is satisfactory, and may, by adding fresh iron from time to time, be made near- ly continuous. The purification depends upon the chemical action of iron on organic matter in solution, and its property of co- agulating very finely divided particles of matter so that they can be removed by fil- tration. The iron, in this process, changes the chemical nature of the organic matter and greatly reduces the albuminoid ammo- nia; softens the hard scales that form in boilers, and destroys or removes much of the infusorial life in the water. A Bit of Triassic History. — Mr. W. M. Davis's study of the " Topographic Devel- opment of the Triassic Formation of the Connecticut Valley " shows that the country from northwest to southeast suffered from repeated faultings after the trap sheets had taken their places, as extensive surface-flows, in the stratified series, the trend of the faults being to the southwest. The initial con- structional regions are represented by the faulted blocks of southern Idaho. A mount- ainous variety of form prevailed — which may provisionally be called the Jurassic stage of the evolution of the district ; but in time — during the Cretaceous — the fault- ed ridges were reduced to a low, base-leveled plain, in which the present valleys were worn after its elevation. The Connecticut River was originally consequent on the monoclinal faulting ; and, while it has entered on a sec- ond cycle of life as a result of the elevation of the lowland that was produced in its first cycle, it still persists in the course it first took. Uranium. — It is now a hundred years since Klaproth (in 17S9) discovered the metal which be named after the planet Uranus, then recently discovered by Her- schcl. Uranic oxide, which is yellow, is used to produce a beautiful golden color, and, with other minerals, opalescent tint3 in glass and porcelain. The pentoxide is black, and is used in the production of 574 THE POPULAR SCIENCE MONTHLY. costly black porcelain and the dark tints in majolica-ware. The chloride of uranium is coming into use as a substitute for the chlo- ride of gold in photography. It is antici- pated that two extensive fields for the em- ployment of the metal will soon be opened. One is as a substitute for gold in electro- plated ware, for with platinum and copper it forms two beautiful yellow alloys. Its platinum alloy has a special value from its power of resistance to the action of acids. The other use will be found in electric in- stallations, and depends on its high elec- trical resistance. Uranium has hitherto been found only in pockets or patches in Bohemia, Saxony, and Cornwall, but in the centennial year of its discovery a lode of the metal which promises a large supply was found in the latter region. A Chemist's Services to Mankind.— In a recent address on the life-work of Pasteur, Sir Henry E. Roscoe emphasized the benefits to humanity which have resulted from the researches of the great French chemist. "The first and obvious endeavor of every cultivator of science," he said, " ought to be to render service of this kind. For, although it is foolish and shortsighted to decry the pursuit of any form of scientific study be- cause it may be as yet far removed from practical application to the wants of man, and although such studies may be of great value as an incentive to intellectual activity, yet the statement is so evident as to almost amount to a truism, that discoveries which give us the power of rescuing a population from starvation, or which tend to diminish the ills that flesh, whether of man or beast, is heir to, must deservedly attract more at- tention and create a more general interest than others having so far no direct bearing on the welfare of the race." Pasteur's se- ries of valuable labors, including the discov- ery of the causes and remedies for the sick- nesses which wine and beer undergo, the cure of the silk-worm disease, the existence of which in one year cost France more than one hundred millions of francs, the extermi- nation of fowl-cholera, and of the fatal dis- ease known as anthrax in cattle and wool- sorters' disease in man, culminates in his dis- covery of a successful treatment for rabies. Prof. Itoscoc gives an idea of the wide de- mand for the treatment of Pasteur's labora- tory in these words : " There I saw the French peasant and the Russian moujik (suffering from the terrible bites of rabid wolves), the swarthy Arab, the English policeman, with women too and children of every age, in all perhaps a hundred patients. All were there undergoing the careful and kindly treat- ment which was to insure them against a horrible death. Such a sight will not be easily forgotten. By degrees this wonder- ful cure for so deadly a disease attracted the attention of men of science throughout the civilized world. The French nation raised a monument to the discoverer better than any statue, in the shape of the ' Pasteur Institute' — an institution devoted to carry- ing out in practice this anti-rabic treatment, with laboratories and every other conven- ience for extending by research our knowl- edge of the preventive treatment of infec- tious disease." The contrast between the spirit of science and the spirit of war is well expressed in Pasteur's own words at the opening of this institute: "Two adverse laws seem to me now in contest. One law of blood and death, opening out each day new modes of destruction, forces nations to be always ready for the battle-field. The other, a law of peace, of work, of safety, whose only study is to deliver man from the calamities which beset him." The Cotton Fiber. — Mr. Thomas Pray, Jr., in a lecture before the Franklin Insti- tute, said that the ordinary way of judging raw cotton by feeling with the fingers was exceedingly crude, seeing that the fibers vary all the way from -^his °f an mcn iQ thickness for the coarsest " upland," to ?oW f°r tne best Sea Island cotton. Some few cotton- spinners have now been induced by Mr. Pray to adopt the microscope in examining cot- ton. The finest cotton raised in any of the fields of the world comes from the Missis- sippi delta. Under the microscope it is seen to be beautiful in structure, of perfect de- velopment, full of oil deposits, and having nearly four hundred spirals per inch. It makes very strong yarn, capable of coloring all the delicate shades, like pink, and bleach- es in the most perfect manner. Dyers fre- quently find spots in cotton goods that will not take color at all, or only unevenly. Cer- NOTES. S7S tain pieces can not be printed or colored anything but black. If fibers of such cot- ton are looked at under the microscope after being mordanted, some parts will be seen prepared for coloring, and others where the mordant has not taken hold. Cotton is often badly damaged by poor ginning ; the fibers are torn, and millions of short pieces to every bale are broken off, which in spinning fly all over the mill and machinery, and go into the waste instead of being made into yarn. Much has been said about "parallelism" of cotton fibers in the manufactured goods, but, if a bit of one of the best grades of cotton cloth made is examined under the microscope, there is seen to be no such thing as parallel- ism among the fibers. Snow - Blindness. — Snow - blindness, ac- cording to Dr. Berlin, of Nordenskiold's Expedition to Greenland of 1883, is met with as far north as any arctic expedition has penetrated, but is unknown, except spo- radically in high mountains, south of cer- tain degrees of latitude. It follows the sinuosities of the isothermal lines. In the arctic regions it breaks out usually in the spring-time, but also occurs in summer wher- ever snow remains. It appears during snow- storms and fogs, as well as when the sun is shining. The prominent symptom is an intense burning pain in the eyes, beginning with a prickling sensation as if produced by a foreign body, with increased secretion of tears, photophobia, and blepharospasm. The visual power is not diminished, but the field is narrowed. Most cases will get well at the end of two or three days, if the patient guards himself against the exciting causes ; or the disease may, exceptionally, become a serious matter. It is not a dazzling caused by the snow, for dazzling does not produce its effects, and it does not prevail everywhere that there are snow and sunlight ; nor can it be explained by the fact of the rarefaction of the air. It is probably a result of the low temperature and the want of humidity in the air which characterize the places where it prevails. As it is the humidity of the air which principally absorbs the radi- ant heat, the caloric rays of the sun must, in those localities, manifest an intensity of action far above the common. Observation has shown that this is the case, for on high mountains and in the arctic regions exposure to the sun's rays produces on the bare skin an excessively painful dermatitis, which the radiant heat reflected by the snow very much aggravates. The effects of exposure to the sun appear to be most severe in spring-time. The eyes are affected simultaneously with the skin or somewhat previously. The or- dinary treatment of snow-blindness consists in the use of spectacles of dark-colored glass, with opiates to relieve the pain. Blacken- ing of the nose has been found by several travelers to be an effective remedy. The Great Hall of the Mammoth Cave. — Some important new discoveries in the Mam- moth Cave were described by the Rev. Dr. H. C. Hovey at the meeting of the American Association. They are connected with the arrangement of the cave passages in tiers and the great pits or domes. Following the guide across a treacherous chasm known as the covered pit, the author found a se- ries of these chasms exceeding in size any that had ever been discovered before. He afterward visited the pits with a photog- rapher, Mr. Ben Hains, and means for tak- ing photographs. As measured from above, they varied from forty-seven to one hun- dred and thirty-five feet in depth. With much difficulty and risk he succeeded in reaching the bottom of Charybdis, the deep- est of the pits, and there discovered, by the aid of chemical fires, that the whole series of pits, eight in all, were joined at the bot- tom into one magnificent hall several hun- dred feet long. This hall was traversed from end to end. Dr. Hovey proposes to name it Harrison's Hall, after the President of the United States. NOTES. A bacterial disease of carnations was described by Prof. J. C. Arthur at the meet- ing of the American Association. It is re- vealed by the presence in the leaves of transparent dots that can be seen only by transmitted light. These spots increase and coalesce, and finally kill the tissues, when the leaves dry up and the plant gradually dies. The transparent spots are found, under the microscope, to be due to the en- largement of the cells with bacteria. When the governor of a province in Madagascar wishes to issue a proclamation, 576 THE POPULAR SCIENCE MONTHLY. he sends out, according to Mr. L. H. Kan- some, messengers to all the villages under his control, bidding the principal men from each to assemble at an appointed time ; this gathering is called a kabary. When all those summoned are present, the governor or his deputy reads aloud the proclamation, which then becomes law, the representa- tives of each village being responsible for its publicity. Sometimes justice is adminis- tered at a kabary of this kind, when the governor pronounces sentence, after hearing the evidence on both sides. A method of sewage purification called the " Amines " process is being tried at Wimbledon (England) Sewage Farm. It is so named because it employs certain basic carbon compounds called amines, together with milk of lime. At present herring- brine is the cheapest substance which contains the amines. When the brine is introduced into freshly made milk of lime it is decomposed and a very soluble reagent is evolved, to which the inventor has given the name " aminol." This substance has a peculiar briny odor, and when introduced into sew- age is said to extirpate all micro-organisms capable of causing putrefaction and disease. A committee of the Royal Society has been appointed on the erection of a national memorial to Dr. Joule. A specimen of the crested starling (Freyilupus varius), of Reunion Island, has recently been obtained for the British Mu- seum. This bird, which has been probably exterminated, is rarer in collections than the great auk. Its coloring consists simply of black, white, and gray, but when alive it must have been a graceful bird. Some Creoles on the islands, who remembered the bird in their younger days, told the late Mr. Pollen that it was so tame and stupid that it could be knocked over with a stick. Only sixteen specimens are known to exist, and there is none in any American museum. Concerning "the grass problem in Ne- braska," Prof. Bessey, at the agricultural meeting of the American Association, men- tioned places where buffalo grass is plentiful, and others where the soil is a moving sand, that gradually becomes covered with native American grasses. In older tracts, timothy has been introduced, Kentucky blue grass is grown successfully, and clovers are doino; well. Prof. Beal, in a paper on " Wild Grasses under Cultivation," said that he had found in his researches many wild grasses that were valuable, and advised selections for experiment. Prof. Fernow is quoted in the " Toronto Globe" as advancing, in an interview, the opinion, respecting the influence of forests on climate, that the lack of moisture on the plains of a large portion of the West was due not so much to deficient rainfall as to excessive evaporation, which in turn was due to the unchecked action of the wind. Were there wind-breaks in the form of patches of trees in that country, part of the land would be thereby reclaimed, and the reclamation of the rest would be rendered far more easy. The proposition of Major Powell, to remove the forests from the crown of the Rocky Mountains, as a means of improving the water conditions of the desert, he regarded as preposterous, and opposed to all our knowledge regarding the natural conditions of mountainous districts. Dr. von Reuben Paschnitz having con- cluded that when earthquake-shocks occur simultaneously at different places, as re- cently happened in Japan and Germany, a connection may be presumed between them, Mr. William White has presented some very forcible arguments in " Nature " in support of an opposite view. A statue of the French chemist, Nicolas Leblanc, has been erected at Saint-Denis, where he had a manufactory. While the enormous output of coal dur- ing the last few years has not actually crippled British fuel resources, Prof. Hull anticipates a general rise in the value of coal in the near future, on account of the great depth at which the mines will have to be worked, and the increased cost of coal- mining. Both the Russian and English engineers are planting trees extensively as an aid to their operations in Central Asia. The Rus- sians, under the direction of General Annen- koff, are especially active in this work. Or- ders have been given that no bushes are to be cut down within ten miles of the Trans- caspian Railway, and that the existing for- ests of saxaul are to be preserved. Planta- tions of this, which is a kind of brier-wood, are to be made alons the line, with camel- thorn and other native bushes that thrive well. It is expected that these will protect the line and provide shelter for weaker trees and bushes of foreign origin. The tree- planting of the last three years has not been a complete success, but experience has shown what varieties will and what will not thrive. The London " Spectator " publishes let- ters showing that the idea that horse-hairs dropped into water in time beget life and become worms or " snakes " prevails exten- sively over Europe as well as America. It is based on the fact that worms resembling short horse-hairs exist, and are not uncom- mon in placid pools. A contributor to the "Spectator" accounts for the experiences of persons who claim to have " seen " the horse-hairs become living, by observing that after lying in the water for a long time a hair swells, assumes the form of a young eel, and, in a way common to many inanimate substances, acquires a slow, wriggling motion.

D., EX-PRESIDENT OF CORNELL UNIVERSITY. PART II. THE first effect of the Protestant Reformation was to popu- larize the older Dead Sea legends, and to make the public mind still more receptive for the newer ones. Luther's great pictorial Bible, so powerful in fixing the ideas of the German people, showed by very striking engravings all three of these earlier myths — the destruction of the cities by fire from heaven, the transformation of Lot's wife, and the vile origin of the hated Moabites and Ammonites ; and we find the salt statue, especially, in this and other pictorial Bibles, during gener- ation after generation. Catholic peoples also held their own in this display of faith. About 1517 Francois Regnault published at Paris a compilation on Palestine enriched with woodcuts ; in this the old Dead Sea legend of the " Serpent Tyrus " reappears embellished, and with it various other new versions of old stories. Five years later Bartholomew de Salignac travels in the Holy Land, vouches for the continued existence of the Lot's wife statue, and gives new life to an old marvel by insisting that the sacred waters of the Jordan are not really poured into the infernal basin of the Dead Sea, but that they are miraculously absorbed by the earth. These ideas were not confined to the people at large ; we trace them among scholars. vol. xxxvi. — 37 578 'THE POPULAR SCIENCE MONTHLY. In 1581 Bunting, a North German professor and theologian, published his "Itinerary of Holy Scripture," and in this the Dead Sea and Lot legends continue to increase. He tells us that the water of the sea " changes three times every day " ; that it " spits forth fire " ; that it throws up " on high " great foul masses which " burn like pitch " and " swim about like huge oxen " ; that the statue of Lot's wife is still there, and that it shines like salt. In 1590 Christian Adrichom, a Dutch theologian, published his famous work on sacred geography. He does not insist upon the Dead Sea legends generally, but declares that the statue of Lot's wife is still in existence, and on his map he gives a picture of her standing at Usdum. Nor was it altogether safe to dissent from such beliefs. Just as, under the papal sway, men of science had been severely pun- ished for wrong views of the physical geography of the earth in general, so, when Calvin decided to burn Servetus, he included in his indictment for heresy a charge that Servetus, in his edition of "Ptolemy," had made unorthodox statements regarding the physical geography of Palestine.* So, too, Protestants and Catholics vied with each other in the making of new myths. Thus, in his " Most Devout Journey," published in 1608, Jean Zvallart, Mayor of Ath in Hainault, con- fesses himself troubled by conflicting stories about the salt statue, but declares himself sound in the faith that " some vestige of it still remains," and makes up for his bit of freethinking by add- ing a new mythical horror to the region — "crocodiles," which, with the serpents and the " foul odor of the sea," prevented his visit to the salt mountains. In 1615 Father Jean Boucher publishes the first of many edi- tions of his " Sacred Bouquet of the Holy Land." He depicts the horrors of the Dead Sea in a number of striking antitheses, and among these is the statement that it is made of mud rather than of water, that it soils whatever is put into it, and so corrupts the land about it that not a blade of grass grows in all that region. In the same spirit thirteen years later, the Protestant Christo- pher Heidmann publishes his " Palsestina," in which he speaks of * For biblical engravings of Lot's wife transformed into a salt statue, etc., see Luther's Bible, 1534, p. xi ; also the pictorial " Electoral Bible " ; also Merian's " Icones Biblicse " of 1625; also the frontispiece of the Luther Bible published at Nuremberg in 1708; also Scheuchzer's " Kupfer Bibel," Augsburg, 1731, Tab. lxxx.

NEW CHAPTERS IN THE WARFARE OF SCIENCE. 579 a fluid resembling blood oozing from the rocks about the Dead Sea, and cites authorities to prove that the statue of Lot's wife still exists and gives signs of life. Yet, as we near the end of the sixteenth century, some evi- dences of a healthful and fruitful skepticism begin to appear. The old stream of travelers, commentators, and preachers, ac- cepting tradition and repeating what they have been told, flows on ; but here and there we are refreshed by the sight of a man who really begins to think and look for himself. First among these is the French naturalist Pierre Belon. As regards the ordinary wonders, he has the simple faith of his time. Among a multitude of similar things, he believed that he saw the stones on which the disciples were sleeping during the prayer of Christ, the stone on which the Lord sat when he raised Laza- rus from the dead, the Lord's footprints on the stone from which he ascended into heaven, and, most curious of all, "the stone which the builders rejected." Yet he makes some advance on his predecessors, since he shows in one passage that he had thought out the process by which the simpler myths of Palestine were made. For, between Bethlehem and Jerusalem, he sees a field covered with small pebbles, and of these he says : " The common people tell you that a man was once sowing peas there, when Our Lady passed that way and asked him what he was doing ; the man answered, fI am sowing pebbles/ and straightway all the peas were changed into these little stones." His ascribing belief in this explanatory transformation-myth to the " common people " marks the faint dawn of a new epoch. Typical also of this new class is the German botanist Leon- hard Rauwolf. He travels through Palestine in 1575, and, though devout and at times credulous, notes comparatively few of the old wonders, while he makes thoughtful and careful mention of things in nature that he really saw ; he declines to use the eyes of the monks, and steadily uses his own to good purpose. As we go on in the seventeenth century, this current of new thought is yet more evident ; a habit of observing more carefully and of comparing observations had set in ; the great voyages of discovery by Columbus, Yasco Da Gama, Magellan, and others were producing their effect, and this effect was increased by the inductive philosophy of Bacon, the reasonings of Descartes, and the suggestions of Montaigne. So evident was this current that, as far back as the early days of the century, a great theologian, Quaresmio, of Lodi, had made up his mind to stop it forever. In 1616, therefore, he began his ponderous work entitled "The Historical, Theological, and Moral Explanation of the Holy Land." He labored upon it for nine years, gave nine years more to perfecting it, and then put it 580 THE POPULAR SCIENCE MONTHLY. into the hands of the great publishing honse of Plantin at Ant- werp ; they were four years in printing and correcting it, and, when it at last appeared, it seemed certain to establish the theo- logical view of the Holy Land for all time. While taking abun- dant care of other myths which he believed sanctified by our sacred books, Quaresmio devoted himself at great length to the Dead Sea, but above all to the salt statue, and divides his chapter on it into three parts, each headed by a question : First, "Hoio was Lot's wife changed into a statue of salt ? " Secondly, " Where was she thus transformed ? " And, thirdly, " Does that statue still exist ? " Through each of these divisions he fights to the end against all who are inclined to swerve in the slightest degree from the orthodox opinion. He utterly refuses to compromise with any modern theorists. To all such he says, " The narration of Moses is historical and is to be received in its natural sense, and no right-thinking man will deny this." To those who favored the figurative interpretation he says, " With such reasonings any passage of Scripture can be denied." As to the spot where the miracle occurred, he discusses four places, but settles upon the point where the picture of the statue is given in Adrichom's map. As to the continued existence of the statue, he plays with the opposing view as a cat fondles a mouse, and then shows that the most revered ancient authorities, venerable men still living, and the Bedouins, all agree that it is still in being. Throughout the whole chapter his thoroughness in scriptural knowledge and his profundity in logic are only ex- celled by his scorn for those theologians who were willing to yield anything to rationalism. So powerful was this argument that it seemed to carry every- thing before it, not merely throughout the Roman obedience, but among the most eminent theologians of Protestantism. As regards the Roman Church, we may take as a type the mis- sionary priest Eugene Roger, who, shortly after the appearance of Quaresmio's book, published his own travels in Palestine. He was an observant man, and his work counts among those of real value ; but the spirit of Quaresmio had taken possession of him fully. His work is prefaced with a map showing the points of most importance in scriptural history, and among these he identi- fies the place where Samson slew the thousand Philistines with the jaw-bone of an ass, and where he hid the- gates of Gaza ; the cavern which Adam and Eve inhabited after their expulsion from paradise ; the spot where Balaam's ass spoke ; the tree on which Absalom was hanged ; the place where Jacob wrestled with the angel ; the steep place where the swine possessed of devils plunged into the sea ; the spot where the prophet Elijah was taken up in a chariot of fire ; and, of course, the position of the salt statue NEW CHAPTERS IN THE WARFARE OF SCIENCE. 581 which was once Lot's wife. He not only indicates places on land, but places in the sea ; thus he shows where Jonah was swallowed by the whale, and " where St. Peter caught one hundred and fifty- three fishes." As to the Dead Sea miracles generally, he does not dwell on them at great length ; he evidently felt that Quaresmio had ex- hausted the subject, but he shows largely the fruits of Quaresmio's teaching in other matters. He sees, describes, and reasons with great theological acuteness upon the basilisk. The animal is about a foot and a half long, shaped like a crocodile, and kills people with its glance. The one which he saw was dead, fortu- nately for him, for in the time of Pope Leo IV, as he tells us, one appeared at Rome and killed many people by merely looking at them, but the Pope destroyed it with his prayers and the sign of the cross. He says that Providence has wisely and merci- fully protected man by requiring the monster to cry aloud two or three times whenever he leaves his cavern, and the divine wisdom has also made it necessary that the monster should look his victim in the eye, and at a certain distance, in order that his glance may penetrate the victim's eye, and so pass at once to his heart. He also gives reason for supposing that the same divine mercy has provided that the crowing of a cock will kill a basilisk. But even in this good and credulous missionary we see the in- fluence of Bacon and the dawn of experimental science ; for, hav- ing been told many stories regarding the salamander, he secured one, placed it alive upon the coals, and reports to us that the legends regarding its power to live in the fire are untrue. He also tried experiments with the chameleon, and found that the stories told regarding it were to be received with much allow- ance ; but, while he uses his mind in these things after the modern method, he locks up his judgment when he discusses the letter of Scripture. A curious example of this we find in his reference to the famous text, in the thirty-eighth chapter of Ezekiel, which led the mediaeval map-makers to place Jerusalem at the center of the earth. Coupling with this a text from Isaiah, he, by a theo- logical argument, satisfies himself that the exact center of the earth is a certain spot marked on the pavement of the Church of the Holy Sepulchre : by a similar process of theological reasoning he also proves that the place where the Holy Cross stood was the identical spot first occupied by the tree which bore the forbidden fruit in the Garden of Eden. So, too, we find the thoughts and words of Quaresmio echoing afar through the German universities, in public disquisitions, dissertations, and sermons. The great Bible commentators, both Catholic and Protestant, generally agreed in accepting them. But, strong as this theological theory was, we find that, as 582 THE POPULAR SCIENCE MONTHLY. time went on, it required to be braced somewhat, and in 1692 Wedelius, Professor of Medicine at Jena, chose as the subject of his inaugural address " The Physiology of the Destruction of Sodom and of the Statue of Salt." It is a masterly example of "sanctified science." At great length he dwells on the characteristics of sulphur, salt, and thun- derbolts ; mixes up scriptural texts, theology, and chemistry after a most bewildering fashion ; and finally comes to the conclusion that a thunderbolt, flung by the Almighty, calcined the body of Lot's wife, and at the same time vitrified its particles into a glassy mass looking like salt.* By such demonstrations as these of Quaresmio and Wedelius the theological view of the myth seemed fastened upon the world forever. Not only was this view demonstrated, so far as theologico- scientific reasoning could demonstrate anything, but it was clearly shown, by a continuous chain of testimony from the earliest ages, that the salt statue at Usdum had been recognized as the body of Lot's wife by Jews, Mohammedans, and the universal Christian Church, " always, everywhere, and by all." Under the influence of teachings like these — and of the winter rains — new wonders began to appear at the salt pillar. In 1661 the Franciscan monk Zwinner published his travels in Palestine, and gave not only all the old myths regarding the salt statue, but a new one, in some respects more striking than any of the old — for he had heard that a dog, also transformed into salt, was stand- ing by the side of Lot's wife. Even the more solid Benedictine scholars were carried away, and we find in the " Sacred History " by Prof. Metzger, of the Order * For Zvallart, see his " Tres devot Voyage a Ierusalem," Antwerp, 1608, book iv, chapter viii.

NEW CHAPTERS IN THE WARFARE OF SCIENCE. 583 of St. Benedict, published in 1700, a renewal of the declaration that the salt statue must be a "perpetual memorial." But it was soon evident that the scientific current was still working beneath this ponderous mass of theological authority. A typical evidence of this we find in 1666 in the travels of Doubdan, a canon of St. Denis. As to the Dead Sea, he says that he saw no smoke, no clouds, and no " black, sticky water " ; as to the statue of Lot's wife, he says, " The moderns do not believe so easily that she has lasted so long " ; then, as if alarmed at his own boldness, he concedes that the sea may be black and sticky in the middle ; and from Lot's wife he escapes under cover of some pious gener- alities. Four years later another French ecclesiastic, Jacques Goujon, referring in his published travels to the legend of the salt pillar, says : " People may believe these stories as much as they choose ; I did not see it, nor did I go there." So, too, in 1697, Morison, a dignitary of the French church, having traveled in Palestine, confesses that, as to the story of the pillar of salt, he has difficulty in believing it. The same current is observed working still more strongly in the travels of the Rev. Henry Maundrell, an English chaplain at Aleppo, who traveled through Palestine during the same year. He pours contempt over the legends of the Dead Sea in general : as to the story that birds could not fly over it, he says that he saw them flying there ; as to the utter absence of life in the sea, he saw small shells in it ; he sees no traces of any buried cities ; and, as to the stories regarding the statue of Lot's wife and the pro- posal to visit it, he says, " Nor could we give faith enough to these reports to induce us to go on such an errand." The influence of the Baconian philosophy on his mind is very clear ; for, in expressing hi? disbelief in the Dead Sea apples, with their contents of ashes, he says that he saw none, and he cites Lord Bacon in support of skepticism on this and similar points. But the strongest effect of this growing skepticism is seen near the end of that century, when the eminent Dutch commentator Clericus published his commentary on the Pentateuch and his " Dissertation on the Statue of Salt." At great length he brings all his shrewdness and learning to bear against the whole legend of the actual transformation of Lot's wife and the existence of the salt pillar, and ends by saying that " the whole story is due to the vanity of some and the credulity of more." In the beginning of the eighteenth century we find new tribu- taries to this rivulet of scientific thought. In 1701 Father Felix Beaugrand dismisses the Dead Sea legends and the salt statue very curtly and dryly — expressing not his belief in it, but a con- ventional wish to believe. 584 THE POPULAR SCIENCE MONTHLY. In 1709 a scholar appeared in another part of Europe and of different faith, who did far more than any of his predecessors to envelop the Dead Sea legends in an atmosphere of truth — Adrian Reland, professor at the University of Utrecht. His work on Pales- tine is a monument of patient scholarship, having as its nucleus a love of truth as truth : there is no irreverence in him, but he quietly brushes away a great mass of myths and legends : as to the statue of Lot's wife, he does not deign to treat it at length, but incident- ally applies the comparative method to it with killing effect, for he shows that the story of its miraculous renewal is but one among many of its kind.* Yet to superficial observers the old current of myth and mar- vel seemed to flow into the eighteenth century as strong as ever, and of this we may take two typical evidences. The first of these is the "Pious Pilgrimage" of Vincent Briemle. His journey was made about 1710 ; and his work, brought out under the auspices of a high papal functionary some years later, in a heavy quarto, gave new life to the stories of the hellish character of the Dead Sea, and especially to the miraculous renewal of the salt statue. In 1720 came a still more striking effort to maintain the old belief on the Protestant side, for, in that year the eminent theo- logian Masius published his great treatise on " The Conversion of Lot's Wife into a Statue of Salt." He evidently intended that this work should be the last word on this subject among Protestants, as Quaresmio had imagined that his work would be the last among Catholics. He develops his subject after the high scholastic and theologic manner. Call- ing attention first to the divine command in the New Testament, " Remember Lot's wife," he argues through a long series of chap- ters. In the ninth of these he discusses " the impelling cause " of her looking back, and introduces us to the question, formerly so often discussed by theologians, whether the soul of Lot's wife was finally saved. Here we are glad to learn that the big, warm heart of Luther lifted him above the common herd of theologians, and led him to declare that she was " a faithful and saintly woman," and that she certainly was not eternally damned. In justice to the Roman Church also it should be said that several of her most * For Zwinner, see his "Blumenbuch des Heyligen Landes," Miinchen, 1661, p. 454.

NEW CHAPTERS IN THE WARFARE OF SCIENCE. 585 eminent commentators took a similar view, and insisted that the sin of Lot's wife was venial, and therefore, at the worst, could only subject her to the fires of purgatory. The eleventh chapter discusses at length the question liow she was converted into salt, and, mentioning many theological opin- ions, dwells especially upon the view of Rivetus — that a thunder- holt, made up apparently of fire, sulphur, and salt, wrought her transformation at the same time that it blasted the land ; and he bases this opinion upon the twenty-ninth chapter of Deuteronomy and the one hundred and seventh Psalm. Later, there is presented a sacred scientific theory that " saline particles entered into her until her whole body was infected " ; and with this Masius connects another piece of sanctified science, to the effect that " stagnant bile " may have rendered the surface of her body " entirely shining, bitter, dry, and deformed/' Finally, in the fourth division of the second section, he comes to the great question whether the salt pillar is still in existence. On this he is full and fair. On one hand he allows that Luther thought that it was involved in the general destruction of Sodom and Gomorrah, and he cites various travelers who had failed to find it ; but, on the other hand, he gives a long chain of evidence to show that it continued to exist : very wisely he reminds the reader that the positive testimony of those who have seen it must outweigh the negative testimony of those who have not, and finally decides that the salt statue is still in being. No doubt a work like this produced a considerable effect in Protestant countries ; indeed, this effect seems evident as far off as England, for, in 1720, we find in Dean Prideaux's " Old and New Testament connected " a map on which the statue of salt is care- fully indicated. So, too, in Holland, in the " Sacred Geography," published at Utrecht in 1758, by the theologian Bachiene, we find him, while showing many signs of rationalism, evidently inclined to the old views as to the existence of the salt pillar; but just here comes a curious evidence of the real direction of the current of thought through the century, for, nine years later, in the German translation of Bachiene's work we find copious notes by the trans- lator in a far more rationalistic spirit ; indeed, we see the dawn of the inevitable day of compromise, for we now have, instead of the old argument that the divine power by one miraculous act changed Lot's wife into a salt pillar, the suggestion that she was caught in a shower of sulphur and saltpeter, covered by it, and that the result was a lump, which, in a general way, is called in our sacred books " a pillar of salt." * * For Briemle, see his " Andachtige Pilgerfahrt," p. 129.

But, from the middle of the eighteenth century, the new cur- rent sets through Palestine with ever-increasing strength. Very- interesting is it to compare the great scriptural commentaries of the middle of this century with those published a century earlier. Of the earlier ones we may take Matthew Poole's " Synopsis " as a type : as authorized by royal decree in 1667 it contains very substantial arguments for the pious belief in the statue. Of the later ones we may take the edition of the noted commentary of the Jesuit Tirinus seventy years later ; while he feels bound to present the authorities, he evidently endeavors to get rid of the subject as speedily as possible under cover of conventionalities ; of the spirit of Quaresmio he shows no trace.* About 1760 came a striking evidence of the strength of this new current. The Abate Mariti then published his book upon the Holy Land ; and, of this book by an Italian ecclesiastic, the most eminent of German bibliographers in this field says that it first broke a path for critical study of the Holy Land. Mariti is entirely skeptical as to the sinking of the valley of Siddim and the overwhelming of the cities. He speaks kindly of a Capuchin Father who saw everywhere at the Dead Sea traces of the divine malediction, while he himself could not see them, and says, " It is because a Capuchin carries everywhere the five senses of faith, while I only carry those of nature." He speaks of " the lies of Josephus," and makes merry over " the rude and shapeless block " which the guide assured him was the statue of Lot's wife, explaining the want of human form in the salt pillar by telling him that this complete metamorphosis was part of her pun- ishment. About twenty years later another remarkable man broaches the subject in what was then known as the "philosophic" spirit — Volney. Between the years 1783 and 1785 he made an extensive journey through the Holy Land and published a volume of trav- els which by acuteness of thought and vigor of style secured gen- eral attention. In these, myth and legend were thrown aside, and we have an account simply dictated by the love of truth as truth. He, too, keeps the torch of science burning by applying his geo- logical knowledge to the regions which he traverses. As we look back over the eighteenth century we see mingled with the new current of thought, and strengthening it, a con- stantly increasing stream of more strictly scientific observation and reflection.

NEW CHAPTERS IN THE WARFARE OF SCIENCE. 587 raldi showed the Paris Academy of Sciences fossil fishes found in the Lebanon region ; a little later, Cornelius Bruyn, in the French edition of his Eastern travels, gave well-drawn representations of fossil fishes and shells, some of them from the region of the Dead Sea. About the middle of the century Richard Pococke, Bishop of Meath, and Korte, of Altona, made more statements of the same sort ; and toward the close of the century, as we have seen, Volney gave still more of these researches, with philosophical deductions from them. The result of all this was that there gradually dawned upon thinking men the conviction that, for ages before the appearance of man on the planet, and during all the period since his appear- ance, natural laws have been steadily in force, and in Palestine as elsewhere ; this conviction obliged men to consider other than supernatural causes for the phenomena of the Dead Sea, and myth and marvel steadily shrank in value. But at the very threshold of the nineteenth century Chateau- briand came into the field, and he seemed to banish the scientific spirit, though what he really did was to conceal it temporarily behind the vapors of his rhetoric. The time was propitious for him. It was the period of reaction after the French Revolution, when what was called religion was again in fashion, and when even atheists supported it as a good thing for common people ; of such an epoch Chateaubriand, with his superficial information, thin sentiment, and showy verbiage, was the foreordained prophet. His enemies were wont to deny that he ever saw the Holy Land ; whether he did or not, he added nothing to real knowledge, but simply threw a momentary glamour over the regions he described, and especially over the Dead Sea. The legend of Lot's wife he carefully avoided, for he knew too well the danger of ridicule in France. As long as the Napoleonic and Bourbon reigns lasted, and in- deed for some time afterward, this kind of dealing with the Holy Land was fashionable, and we have a long series of men, espe- cially of Frenchmen, who evidently received their impulse from Chateaubriand. About 1831 De Geramb, Abbot of La Trappe, evidently a very noble and devout spirit, sees vapor above the Dead Sea, but stretches the truth a little — speaking of it as " vapor or smoke." He could not find the salt statue, and complains of the "diversity of stories regarding it." The simple physical cause of this di- versity— the washing out of different statues in different years — never occurs to him, but he comforts himself with the scriptural warrant for the metamorphosis.* * For Mariti, see his " Voyage," etc., vol. ii, pp. 352-356.

But to the honor of scientific men and scientific truth it should he said that even under Napoleon and the Bourbons there were men who continued to explore, observe, and describe with the simple love of truth as truth, and in spite of the probability that their researches would be received during their lifetime with con- tempt and even hostility both in church and state. The pioneer in this work of the nineteenth century was the German naturalist Ulrich Seetzen. He began his main investi- gation in 1806, and soon his learning, courage, and honesty threw a flood of new light into the Dead Sea questions. In this light, myth and legend faded more rapidly than ever. Typical of his method is his examination of the Dead Sea fruit. He found, on reaching Palestine, that Josephus's story regarding it, which had been accepted for nearly two thousand years, was believed on all sides ; more than this, he found that the original myth had so grown that a multitude of respectable people at Bethlehem and elsewhere assured him that not only apples, but pears, pomegranates, figs, lemons, and many other fruits which grow upon the shores of the Dead Sea, though beautiful to look upon, were filled with ashes. These good people declared to Seetzen that they had seen these fruits, and that, not long before, a basketful of them which had been sent to a merchant of Jaffa had turned to ashes. Seetzen was evidently perplexed by this mass of testimony, and naturally anxious to examine these fruits. On arriving at the sea he began to look for them, and the guide soon showed him the " apples." These he found to be simply an asclepia, which had been described by Linnaeus, and which is found in the East Indies, Arabia, Egypt, Jamaica, and elsewhere ; the " ashes " were simply seeds. He looked next for the other fruits, and the guide soon found for him the " lemons " ; these he discovered to be a species of solarium found in other parts of Palestine and elsewhere, and the seeds in these were the famous " cinders." He looked next for the pears, figs, and other accursed fruits ; but, instead of finding them filled with ashes and cinders, he found them like the same fruits in other lands, and he tells us that he ate the figs with much pleasure. So perished a myth which had been kept alive two thousand years, partly by modes of thought natural to theologians, partly by the self-interest of guides, and partly by the love of marvel- mongering among travelers.

As to the appearance of the sea, he found its waters not "black and sticky," but blue and transparent; he found no smoke rising from the abyss, but tells us that sunlight and cloud and shore were pleasantly reflected from the surface. As to Lot's wife, he found no salt pillar which had been a careless woman, but the Arabs showed him many bowlders which had once been wicked men. His work was worthily continued by a long succession of true and reverent men, among them such travelers or geographers as Burckhardt, Irby, Mangles, Fallmerayer, and Carl von Raumer : by men like these the atmosphere of myth and legend was stead- ily cleared away ; as a rule, they simply forgot Lot's wife alto- gether. Greatest of all in this noble succession was an American theo- logian, Dr. Edward Robinson, professor at New York, a man of whom his country and humanity may well be proud. Beginning about 1826, he devoted himself for thirty years to the thorough study of the geography of Palestine, and he found a worthy coadjutor in another American divine, Dr. Eli Smith. Neither of these men departed openly from the old traditions; that would have cost a heart-breaking price, the loss of all further opportunity to carry on their researches. Robinson did not even think it best to call attention to the mythical character of much on which his predecessors had insisted ; he simply brought in, more and more, the dry, clear atmosphere of the love of truth for truth's sake, and, in this, myths and legends steadily disappeared. By doing this he rendered a far greater service to real Chris- tianity than any other theologian had ever done in this field. Very characteristic is his dealing with the myth of Lot's wife. Though more than once at Usdum, though giving valuable in- formation regarding the sea, shore, and mountains there, he care- fully avoids all mention of the salt pillar and of the legend which arose from it. In this he set an example followed by most of the more thoughtful religious travelers since his time. Very significant is it to see the New Testament injunction, " Remem- ber Lot's wife," so utterly forgotten. These later investigators seem never to have heard of it, and this constant forgetfulness shows the change which had taken place in the enlightened thinking of the world. But in the year 1848 came an episode very striking in its character and effect. At that time, the war between the United States and Mexico having closed, Lieutenant Lynch, of the United States Navy, found himself in the port of Vera Cruz, commanding an old hulk, the Supply. Looking about for something to do, it occurred to him to write to the Secretary of the Navy asking permission to 59o THE POPULAR SCIENCE MONTHLY. explore the Dead Sea. Under ordinary circumstances the pro- posal would doubtless have been strangled with red tape ; but fortunately the Secretary at that time was Mr. John Y. Mason, of Virginia. Mr. Mason was famous for his good nature : both at Washington and at Paris, where he was afterward minister, this predominant trait has left a multitude of amusing traditions ; it was of him that Thomas Benton said, " To be supremely happy he must have his paunch full of oysters and his hands full of cards." The Secretary granted permission, but evidently gave the matter not another thought. As a result, came an expedition the most comical and one of the most rich in results to be found in American annals. Never was anything so happy-go-lucky. Lieutenant Lynch started with his hulk, with hardly an instru- ment save those ordinarily found on shipboard, and with a body of men probably the most unfit for anything like scientific inves- tigation ever sent on such an errand ; fortunately, he picked up a young instructor in mathematics, Mr. Anderson, and added to his apparatus two strong iron boats. Arriving, after a tedious voyage, on the coast of Asia Minor, he set at work. He had no adequate preparation in general his- tory, archseology, or the physical sciences, but he had his Ameri- can patriotism, energy, pluck, pride, and devotion to duty, and these qualities stood him in good stead. With great labor he got the iron boats across the country. Then the tug of war began. First of all investigators, he forced his way through the whole length of the river Jordan and from end to end of the Dead Sea. There were constant difficulties, geographical, climatic, and per- sonal, but Lynch cut through them all. He was brave or shrewd, as there was need. Anderson proved an admirable helper, and together they made surveys of distances, altitudes, depths, and sundry simple investigations in a geological, mineralogical, and chemical way. Much was poorly done, much was left undone, but the general result was most honorable both to Lynch and Anderson, and Secretary Mason found that his easy-going patron- age of the enterprise was the best act of his official life. The results of this expedition on public opinion were most curious. Lynch was no scholar in any sense; he had traveled little, and thought less on the real questions underlying the whole investigation ; as to the difference in depth of the two parts of the lake, he jumped — with a sailor's disregard of logic — to the conclusion that it somehow proved the mythical account of the overwhelming of the cities, and he indulges in reflections of a sort probably suggested by his recollections of American Sunday schools. Especially noteworthy is his treatment of the legend of Lot's wife. He found the pillar of salt. It happened to be at that NEW CHAPTERS IN THE WARFARE OF SCIENCE. 591 period a circular column of friable salt rock, about forty feet high ; yet, while he accepts every other old myth, he declares the belief that this was once the wife of Lot " a superstition." One little circumstance added enormously to the influence of this book, for, as a frontispiece, he inserted a picture of the salt column. It was delineated in rather a poetic manner; light streamed upon it, heavy clouds hung above it, and as a back- ground were ranged buttresses of salt rock, furrowed and chan- neled out by the winter rains : this salt statue picture was spread far and wide, and in thousands of country pulpits and Sunday schools it was shown as a tribute of science to Scripture. Nor was this influence confined to American Sunday-school children, for Lynch had innocently set a trap into which several European theologians stumbled. One of these was Dr. Lorenz Gratz, Vicar-General of Augsburg, a theological professor. In the second edition of his " Theatre of the Holy Scriptures," published in 1858, he hails Lynch's discovery of the salt pillar with joy ; for- gets his allusion to the old theory regarding it as a superstition ; and does not stop to learn that this was one of a succession of statues washed out yearly by the rains, but accepts it as the origi- nal Lot's wife. The French churchmen suffered most. About two years after Lynch, De Saulcy visits the Dead Sea to explore it thoroughly, evidently in the interest of sacred science — and of his own pro- motion. Of the modest thoroughness of Robinson there is no trace in his writings. He promptly discovered the overwhelmed cities, which no one before or since has ever found, poured con- tempt on other investigators, and threw over his whole work an air of piety. But, unfortunately, having a Frenchman's dread of ridicule, he attempted to give a rationalistic explanation of what he calls " the enormous needles of salt washed out by the winter rain," and their connection with the Lot's wife myth, and declared his firm belief that she, " being delayed by curiosity or terror, was crushed by a rock which rolled down from the mount- ain, and when Lot and his children turned about they saw at the place where she had been only the rock of salt which covered her body." But this would not do at all, and an eminent ecclesiastic pri- vately and publicly expostulated with De Saulcy — very naturally declaring that " it was not Lot who wrote the book of Genesis." The result was that another edition of De Saulcy's work was published by a Church Book Society, with the offending passage omitted ; but a passage was retained really far more suggestive of heterodoxy, and this was an Arab legend accounting for the origin of certain rocks near the Dead Sea curiously resembling salt formations ; this in effect ran as follows : 592 THE POPULAR SCIENCE MONTHLY. " Abraham, the friend of God, having come here one day with his mule to buy salt, the salt-workers impudently told him that they had no salt to sell, whereupon the patriarch said: 'Your words are true ; you have no salt to sell,' and instantly the salt of this whole region was transformed into stone, or rather into a salt which has lost its savor." Nothing could be more sure than this story to throw light into the mental and moral process by which the salt pillar myth was originally created. In the years 1864 and 1865 came an expedition on a much more imposing scale — that of the Due de Luynes. His knowledge of archaeology and his wealth were freely devoted to working the mine which Lynch had opened, and, taking with him an iron ves- sel and several savants, he devoted himself especially to finding the cities of the Dead Sea, and to giving less vague accounts of them than those of De Saulcy. But he was disappointed, and honest enough to confess his disappointment. So vanished one of the most cherished parts of the legend. But worse remained behind. In the orthodox duke's company was an acute geologist, Monsieur Lartet, who in due time made an elaborate report, which let a flood of light in upon the whole region. The Abbe" Richard had been rejoicing the orthodox heart of France by exhibiting some prehistoric flint implements as the knives which Joshua had made for circumcision. By a truthful statement Monsieur Lartet set all France laughing at him, and then turned to the geology of the Dead Sea basin. While he con- ceded that man may have seen some volcanic crisis there toward its end, and may have preserved a vivid remembrance of the vapor then rising, his whole argument showed irresistibly that all the phenomena of the region are due to natural causes, and that so far from a sudden rising of the lake above the valley within historic times, it has been for ages steadily subsiding. Since Balaam was called by Balak to curse his enemies, and " blessed them altogether," there has never been a more unexpected tribute to truth. Even the salt pillar at Usdum, as depicted in Lynch's book, aided to undermine the myth among thinking men, for the back- ground of the picture showed them other pillars of salt in process of formation ; and the ultimate result of all these expeditions of the century was to spread an atmosphere in which myth and legend became more and more attenuated. To sum up the main points in this work of the nineteenth cent- ury, Seetzen, Robinson, and others had found that a human being could traverse the lake without being killed by hellish smoke ; that the water gave forth no odors : that the fruits of the region NEW CHAPTERS IN THE WARFARE OF SCIENCE. 593 were not created full of cinders to match the desolation of the Dead Sea, but were growths not uncommon in Asia Minor and elsewhere ; in fact, that all the phenomena were due to natural causes. Ritter and others had shown that all noted features of the Dead Sea and the surrounding country were to be found in vari- ous other lakes and regions, to which no supernatural cause was ascribed among enlightened men. Lynch, Van de Velde, Osborne, and others had revealed the fact that the " pillar of salt " was frequently formed anew by the rains ; and Lartet and other geologists had given a final blow to the myths by making it clear from the markings on the neighboring rocks that, instead of a sudden upheaval of the sea above the valley of Siddim, there had been a gradual subsidence for ages.* Even before all this evidence was in, a judicial decision had been pronounced upon the whole question by an authority both Christian and scientific, from which there could be no appeal. During the second quarter of the century Prof. Carl Ritter, of the University of Berlin, began giving to the world those researches which have placed him at the head of all geographers ancient or modern, and finally he brought together those relating to the geography of the Holy Land, publishing them as part of his great work on the physical geography of the earth. He was a Chris- tian, and nothing could be more reverent than his treatment of the whole subject ; but his German honesty did not permit him to conceal the truth, and he simply classed together all the stories of the Dead Sea — old and new — no matter where found, whether in the sacred books of Jews, Christians, or Mohammedans ; whether in lives of saints or accounts of travelers, as " myths " and " sagas." From this decision there has never been among intelligent men any appeal. * For Seetzen, see his " Reisen," edited by Kruse, Berlin, 1854-'59; for the "Dead Sea Fruits," vol. ii, p. 231 et seq. ; for the appearance of the sea, etc., p. 243, and else- where ; for the Arab transformation explanatory legends, vol. iii, pp. 7, 14, 17.

The adjustment of recent orthodox thought to this view pre- sents some curious features. As typical we may take the travels of two German theologians between 1860 and 1870 — John Kranzel, pastor in Munich ; and Peter Schegg, lately professor in the uni- versity of that city. The archdiocese of Munich-Freising is one of those in which the attempt to oppress modern scientific thought has been most steadily carried on. Its archbishops have constantly shown them- selves assiduous in securing cardinals' hats by thwarting science and by stupefying education. The twin towers of the old cathe- dral of Munich have seemed to throw a killing shadow over intel- lectual development in that region. Naturally, then, these two clerical travelers from that diocese did not commit themselves to clearing away any of the Dead Sea myths ; but it is significant that neither of them follows the example of so many of their clerical predecessors in defending the salt-pillar legend; they steadily avoid it altogether. The more recent history of the salt pillar, since Lynch, de- serves mention. It appears that the travelers immediately after him found it shaped by the storms into a spire ; that a year or two later it had utterly disappeared ; and about the year 1870 Prof. Palmer on visiting the place found at some distance from the main salt bed, as he says, " a tall, isolated needle of salt or salt rock, which does really bear a curious resemblance to an Arab woman with a child on her shoulders." Three years later Smith's " Dictionary of the Bible " makes its concession to the old belief regarding Sodom and Gomorrah as slight as possible, and the myth of Lot's wife entirely disappears. The theological effort to compromise with science now came in more strongly than ever. This effort had been made long before : as we have seen, it had begun to show itself decidedly as soon as the influence of the Baconian philosophy was felt. Clerc thought that the shock caused by the sight of fire from heaven killed Lot's wife instantly and made her body rigid as a statue. Eich- horn suggested that she fell into a stream of melted bitumen. Michaelis suggested that her relatives raised a monument of salt rock to her memory. Friedrichs suggested that she fell into the sea, and that the salt stiffened around her clothing, thus making a statue of her. Some claimed that a shower of sulphur came down upon her, and that the word which has been translated " salt " could possibly be translated '" sulphur." Others hinted that the salt by its antiseptic qualities preserved her body as a mummy. De Saulcy, as we have seen, thought that a piece of salt rock fell upon her ; and very recently Principal Dawson ventures the explanation that a flood of salt mud coming from a volcano incrusted her. NEW CHAPTERS IN THE WARFARE OF SCIENCE. 595 But theologians themselves were the first to show the inade- quacy of these explanations. The more rationalistic pointed out the fact that they were contrary to the sacred text : Von Bohlen, an eminent professor at Konigsberg, in his sturdy German hon- esty, declared that the salt pillar gave rise to the story, and com- pared the pillar of salt causing this transformation legend to the rock in Greek mythology which gave rise to the transformation legend of Niobe. On the other hand, the more severely orthodox protested against such attempts to explain away the clear statements of Holy Writ. Dom Calmet, while presenting many of these explanations made as early as his time, gives us to understand that nearly all theolo- gians adhered to the idea that Lot's wife was instantly and really changed into salt ; and in our own time, as we shall presently see, have come some very vigorous protests. Similar attempts were made to explain the other ancient le- gends regarding the Dead Sea. One of the most recent of these is that the cities of the plain, having been built with blocks of bituminous rock, were set on fire by lightning, a contemporary earthquake helping on the work. Still another is that accumula- tions of petroleum and inflammable gas escaped through a fissure, took fire, and so produced the catastrophe.* Against this sort of rationalism perhaps the most vigorous of recent protests appeared in 1876, in an edition of Monseigneur Mislin's work on " The Holy Places." In order to give weight to the book, he spread his qualities at great length on the title-page. Among other things, he was prelate of the papal household, apos- tolic prothonotary, a doctor of theology and of philosophy, and his work is prefaced by letters from Pope Pius IX and sundry high ecclesiastics — and from Alexandre Dumas. His hatred of Protestant missionaries in the East is phenomenal ; he calls them " bagmen," ascribing all mischief and infamy to them ; and his hatred is only exceeded by his credulity. He cites all the argu- ments in favor of the salt statue at Usdum as the identical one into which Lot's wife was changed, adds some of his own, and pre- sents her as " a type of doubt and heresy." With the proverbial facility of theologians in translating any word of a dead language into anything that suits their purpose, he says that the word in the nineteenth chapter of Genesis, which is translated " statue " or " pillar," may be translated " eternal monument " ; he is especially * For Kranzel, see his " Reise nach Jerusalem," etc. ; for Schegg, his " Gedenkbuch einer Pilgerreise," etc., 186V, chapter xxiv.

Nor did such rationalizing efforts fare much better among Protestant theologians. In his excellent work on " The Land of Israel/' Canon Tristram makes an energetic protest against scien- tific explanations of biblical statements. Between 1870 and 1880 came two killing blows at the older theories, and they were dealt by two American scholars of the highest character. First of these may be mentioned Dr. Philip Schaff, a professor in the Presbyterian Theological Seminary at New York; who published his travels in 1877. In a high degree he united the scientific with the religious spirit, but the trait which made him especially fit for dealing with this subject was his straightforward German honesty. He tells the simple truth regarding the pillar of salt, so far as its physical origin and characteristics are concerned, and leaves his reader to draw the natural inference as to its relation to the myth. With the fate of Dr. Robertson Smith in Scotland and Dr. Woodrow in South Carolina before him — both recently driven from their professor- ships for truth-telling — Dr. Schaff deserves honor for telling as much as he does. Similar in effect, and even more bold in statement, were the " Travels " of the Rev. Henry Osborne, published in 1878. In a truly scientific spirit he calls attention to the similarity between the Dead Sea, with, the river Jordan, to sundry other lake and river systems ; he points out the endless variations between writers describing the salt formations at Usdum ; accounts rationally for these variations, and quotes from Dr. Anderson's report, say- ing, " From the soluble nature of the salt and the crumbling looseness of the marl, it might be well imagined that, while some of these needles are in process of formation, others are being washed away." Thus came out, little by little, the truth regarding the Dead Sea myths, and especially the salt pillar at Usdum ; but the final truth remained to be told, and now one of the purest men and truest divines of this century told it. Arthur Stanley, Dean of Westminster, visiting the country and thoroughly exploring it, allowed that the physical features of the Dead Sea and its shores suggested the myths and legends, and he sums up the whole as follows : " A great mass of legends and exaggerations, partly the cause and partly the result of the old belief that the cities were buried under the Dead Sea, has been gradually removed in recent years." So, too, about the same time, Dr. Conrad Furrer, pastor of the NEW CHAPTERS IN THE WARFARE OF SCIENCE. 597 great church of St. Peter at Zurich, gave to the world a book of travels reverent and thoughtful, and, in this, honestly acknowl- edged that the needles of salt at the southern end of the Dead Sea " in primitive times gave rise to the tradition that Lot's wife was transformed into a statue of salt." Thus was the mythical char- acter of this story at last openly confessed by leading churchmen on both continents. Plain statements like these from such sources left the high theological position more difficult than ever, and now a new com- promise was attempted. As the Siberian mother tried to save her best-beloved child from the pursuing wolves by throwing over to them her less favored children, so an effort was now made in a leading commentary to save the legends of the valley of Siddim and the miraculous destruction of the cities by throwing over- board the legend of Lot's wife.* But even this utterly failed, for there soon followed the worst blows of all. First, from Van de Velde, who made his journey in 1851 and 1852. He is a most devout man, but he confesses that the volcanic action at the Dead Sea must have been far earlier than the catastrophe mentioned in our sacred books, and that " the overthrow of Sodom and Gomorrah had nothing to do with this." A few years later a very eminent dignitary of the English Church, Canon Tristram, doctor of divinity and fellow of the Royal Society, who had explored the Holy Land thoroughly, after some generalities about miracles, gave up the whole attempt to make science agree with the myths, and used these words : " It has been frequently assumed that the district of Usdum and its sister cities was the result of some tremendous geological ca- tastrophe. . . . Now, careful examination by competent geologists, such as Monsieur Lartet and others, has shown that the whole district has assumed its present shape slowly and gradually through a succession of ages, and that its peculiar phenomena are similar to those of other lakes." So sank from view the whole mass of Dead Sea myths and legends, and science gained a victory both for geology and comparative mythology. An amusing result has followed this development of opinion. As we have already seen, traveler after traveler, Catholic and Protestant, now visits the Dead Sea, and hardly one of them follows the New Testament injunction to " remember Lot's wife." Nearly every one of them seems to think it best to forget her. * For Mislin, see his " Les Saints Lieux," Paris, 1876, vol. iii, pp. 290-29S, especially note at foot of page 292.

Of the great mass of pious legends they are shy enough, but that of Lot's wife, as a rule, they seem never to have heard of, and, if they do allude to it, they simply cover the whole subject with a haze of conventionality and sacred rhetoric* Naturally, under this state of things, there has followed the usual attempt to throw off from Christendom the responsibility of the old belief, and in 1887 came a curious effort of this sort. In that year appeared the Rev. Dr. Cunningham Geikie's valu- able work on " The Holy Land and the Bible." In it he makes the following statement as to the salt formation at Usdum : " Here and there, hardened portions of salt, withstanding the water, while all around them melts and wears off, rise up isolated pillars, one of which bears among the Arabs the name of Lot's wife." In the light of the previous history, there is something at once pathetic and comical in this attempt to throw the myth upon the shoulders of the poor Arabs. The myth was not originated by Mohammedans ; it appears, as we have seen, first among the Jews, and, I need hardly remind the reader, comes out in the Book of Wisdom and in Josephus, and has been steadily main- tained by fathers, martyrs, and doctors of the Church, by at least one pope, and by innumerable bishops, priests, monks, commenta- tors, and travelers, Catholic and Protestant, ever since. In thus throwing the responsibility of the myth upon the Arabs Dr. Geikie appears to show both the " perf ervid genius " of his coun- trymen and their incapacity to recognize a joke. Nor is he more happy in his rationalistic explanations of the whole mass of myths. He supposes a terrific storm, in which the lightning kindled the combustible materials of the cities, aided perhaps by an earthquake ; but this shows a disposition to break away from the exact statements of the sacred books which would have been most severely condemned by the universal Church during at least eighteen hundred years of its history. Nor would the explanations of Sir William Dawson have fared any better : it is very doubtful whether either of them could escape unscathed to-day from a synod of the Free Church of Scotland, or of any of the leading orthodox bodies in the Southern States of the Ameri- can Union, f * The only notice of the Lot's wife legend in the editions of Robinson at my command is a very curious one by Leopold von Buch, the eminent geologist. Robinson, with a fear- lessness which does him credit, consulted Von Buch, who in his answer was evidently in- clined to make things easy for Robinson by hinting that Lot was so much struck with the salt formations that he imagined that his wife had been changed into salt. On this theory Robinson makes no comment. See Robinson, " Biblical Researches in Palestine," etc., London, 1841, vol. ii, p. 674. f For these most recent explanations, see Rev. Cunningham Geikie, D.

NEW CHAPTERS IN THE WARFARE OF SCIENCE. 599 How unsatisfactory all such rationalism, must be to a truly theological mind is seen not only in the dealings with Prof. Rob- ertson Smith in Scotland and Prof. Woodrow in South Carolina, but, most clearly, in a book published in 1886 by Monseigneur Hausman de Wandelbourg. This work appeared in two ponder- ous volumes and with a great flourish of trumpets. To the name of the author was attached a long list of titles : among other things, he is Prelate of the Pope's Household, a Mitred Abbot, Canon of the Holy Sepulchre, and a Doctor of Theology of the Pontifical University at Rome, and the work is introduced by approving letters from Pope Leo XIII and the Patriarch of Jeru- salem. Monseigneur de Wandelbourg scorns the idea that the salt column at Usdum is not the statue of Lot's wife ; he points out not only the danger of yielding this evidence of miracle to rationalism, but the fact that the divinely inspired authority of the Book of Wisdom, written, at the latest, two hundred and fifty years before Christ, distinctly refers to it. He summons Josephus as a witness. He dwells on the fact that Pope St. Clement, Ire- naeus, Hegesippus, and St. Cyril, " who as Bishop of Jerusalem must have known better than any other person what existed in Palestine," with St. Jerome, St. Chrysostom, and a multitude of others, attest as a matter of their own knowledge or of popular notoriety that the remains of Lot's wife really existed in their time in the form of a column of salt ; and he points triumphantly to the fact that Lieutenant Lynch found this very column. In the presence of such a continuous line of witnesses, some of them divinely inspired, and all of them greatly revered — a line extending through thirty-seven hundred years — he condemns most vigorously all those who do not believe that the pillar of salt now at Usdum is identical with the wife of Lot, and stigma- tizes them as people who " do not wish to believe the truth of the word of God." His ignorance of many of the simplest facts bear- ing upon the legend is very striking, yet he does not hesitate to speak of men who know far more and have thought far more upon the subject as "grossly ignorant." The most laughable feature in his ignorance is the fact that he is utterly unaware of the annual changes in the salt statue. He is entirely ignorant of such facts as that the priest Gabriel Giraudet in the sixteenth century found the statue lying down; that the monk Zwinner found it in the seventeenth century standing, and accompanied by a dog also transformed into salt ; that Prince Radziwill found no statue at all ; that the pious Vincent Briemle in the eighteenth century found the monument renewing itself; that about the middle of the nineteenth century Lynch found it in the shape of a tower or column forty feet high ; that within two years afterward De Saulcy found it washed into the form of a spire ; that a year 600 THE POPULAR SCIENCE MONTHLY. later Van de Velde found it utterly washed away ; and that a few years later Palmer found there " a statue bearing a striking re- semblance to an Arab woman with a child in her arms." Thus ended the last great demonstration thus far on the side of sacred science — the last retreating shot from the theological rear-guard. It is but just to say that a very great share in the honor of the victory of science in this field is due to men trained as theolo- gians. It would naturally be so, since few others have devoted themselves to direct labor in it ; yet great honor is none the less due to such men as Reland, Mariti, Robinson, Smith, Schaff, Stan- ley, and Tristram. They have rendered even a greater service to religion than to science, for they have made a beginning, at least, of doing away with that enforced belief in myths as history which has become a most serious danger to Christianity. For the worst enemy of Christianity could wish nothing more than that its main leaders should prove or insist that it can not be adopted save by those who accept, as historical, statements which enlightened men throughout the world know to be mythi- cal. The result of such a demonstration would only be more and more to make thinking people inside the church dissemblers, and thinking people outside, scoffers. Far better is it to welcome the aid of science, in the conviction that all truth is one, and, in the light of this truth, to allow the- ology and science to work together in the steady evolution of religion and morality. The revelations made by the sciences which most directly deal with the history of man all converge in the truth that during the earlier stages of this evolution moral and spiritual teachings must be inclosed in myth, legend, and parable. " The Master " felt this when he gave to the poor peasants about him — and so to the world— his simple and beautiful illustrations. In making this truth clear, science will give to religion far more than it will take away, for it will throw new life and light into all sacred lit- erature. The origin of the Malays is traced by Dr. B. Hagen to the highlands of west Sumatra, whence the peoples extended slowly eastward; the first movement be- ing probably by the races that are now to be found only in the interior of the great islands. These " aborigines " of the islands crushed out a population already in possession, as remains of which the negritos may be taken. The Malays in the narrower sense occupying Sumatra, Malacca, and north Borneo, are to be regarded as the last emigration from this center, which occurred between the twelfth and fifteenth centuries a. d. Crosses and mixtures arose with the Indians and Chinese, who have been long in intercourse with the archipelago, and in less measure also with the Arabs. For this reason we must not expect to find the pure racial type, especially not in the coast population. THE MISSION OF EDUCATED WOMEN. 601 THE MISSION OF EDUCATED WOMEN. By Mrs. M. F. AKMSTKONG. " Love seldom haunts the breast Where learning lies." — Pope. " 'Tis Reason's part, To govern and to guard the heart." — Cotton. " I loved her well ; I would have loved her better Had love been met with love ; As 'tis, I leave her To brighter destinies, if so she deems them." — Byron. AN article entitled " Plain Words on the Woman Question," - reprinted from the " Fortnightly Review " in this magazine, is so far in the nature of an attack upon the women whom the writer calls into court as to make reply, from one or another quarter, legitimate, and indeed, I think, obligatory. As a woman, who is bound by the conditions of wife and motherhood, for which Mr. Allen makes so able a plea, I can not individually appear on either side. It is not the women whom I represent who are under discussion, but none the less are the principles involved of the deepest and most pressing interest to thoughtful women everywhere, whether they have elected the single-handed fight, or the less evident but none the less serious test which comes with motherhood and the endeavor to make a home. My excuse, therefore, for offering myself, in a sense, as a mouth- piece for the women whom Mr. Allen classifies as " deplorable accidents " is, first, that the points raised are in reality of as much importance to married women as to their unmarried sisters ; and, second, that my position gives me, I think, unusual advantages for getting at certain underlying facts. I have been for years connected with a large educational insti- tution, where young men and women are working, side by side, under identically similar influences. The officials and teachers in this school are largely women, and women who, to quote Mr. Allen, have become " traitors to their sex," in that they have taken upon their shoulders the burden of their own support. They are, with few exceptions, highly educated, many of them college-bred, three among them being regular physicians, while all of them, if I may be permitted to judge, are of at least average attractiveness. As to health, social position, and previous con- dition, they offer also, I believe, a fair average, while their intel- lectual standards mark them high in the scale of feminine de- velopment. For years they have puzzled me, for they are, without doubt, representative of a social phase, and the reasons for their exist- 6oz THE POPULAR SCIENCE MONTHLY. ence, as well as the future to which they point, offer a unique temptation to the theorist. The appearance of the article already- alluded to gave me a long-desired opportunity, and I at once laid it before my friends, asking for it their serious consideration. Nowhere in America, I am sure, could the opportunity be more complete, or the response more telling ; and I trust that what these women have to say for themselves will not be without interest, to those at least who have read Mr. Allen's frank and, on the whole, liberal article. In a charming cottage, occupied by two of this misguided sis- terhood, to whose menage the most critical eye could find nothing lacking, there was gathered, a week or two since, an unmistaka- bly striking assemblage of single women, well looking, well dressed, ranging from twenty to fifty years of age, every one of whom could have, in the past, married, or could still marry, were it her desire to do so. There was not a fanatic among them ; they were sensible, ear- nest, in some cases brilliant women, who had, with more or less intention, turned their backs upon marriage, and chosen instead lives of self-supporting indejDendence. Why have they done this ? Undoubtedly it is to more than one cause that we must look for this result ; but, at the outset of the discussion, it was universally admitted that Mr. Allen is right in considering the " higher edu- cation," to which he objects, to be the most potent factor in the situation. Furthermore, the knowledge of life in all its phases, which these women have gained, both from their intellectual train- ing and their practical experience as bread-winners for them- selves and others, makes them ready to accept most of his other premises. They admit, that is, the physical necessity for maternity, and no man can appreciate its sacredness as they do. They admit, again, the necessity for that tremendous over- loading of the sexual instinct, whose meaning Emerson interprets when he says : " The lover seeks in marriage his private felicita- tion and perfection, with no prospective end ; and Nature hides in his happiness her own end, namely, progeny, or the perpetuity of the race." They admit, too, the value of the institution of marriage, and, as in the case of the ideal motherhood, put its beauty and its possibilities of happiness far beyond the usual masculine concep- tion. As to the continuance of the race, they are far too keen to blink any facts, even when they count against themselves. The race, at all costs, must go on, and women must be wives and mothers, or, to keep exactly to the lines laid down by Mr. Allen, must at least be mothers, to the end of time. And, following THE MISSION OF EDUCATED WOMEN. 603 their logic to the bitter end, they admit that, under existing con- ditions, and probably for long periods yet to come, the women who assume motherhood as their vocation must be prepared to renounce, more or less completely, their chance for intellectual development. To this point our argument, on the evening of which I speak, went smoothly enough. Little or no exception was taken to Mr. Allen's position. So long as he made himself only an exponent of natural laws, and of their inevitable effect upon the social fabric, there were no dissentient voices. But there came a mo- ment when the qnestion must be put point blank, and it was then that, for the first time, we, so to speak, came down to business. " Now," I said, from my vantage-ground of neutrality, " you have cleared the decks. No social philosopher can demand more hearty agreement with the principles of his science than you have given ; no man could desire more generous acknowledgment of man's place in creation, or of the fundamental relations of the sexes, than you offer; but the main issue is still untouched. Tell me why you, as representative individuals, have not married, do not marry, and are endeavoring, so far as educational methods can do it, to perpetuate your type ? " Masculine critics will possibly here suggest that a truthful answer to the first of these questions was far and away beyond my reach ; but the women to whom I was speaking were fully in earnest, and there were no evasions. " In the first place," said a clever woman beside me, " while we deny that our education unsexes us, we are conscious that it gives us a self-control, a balance, which is of inestimable advantage to us in the practical affairs of life, and induces us to consider marriage from more than one point of view. In the past, it is the emotional nature of women which has been cultivated, often at a heavy cost. Now, her intellect is taking charge, and we believe that there is no longer any reason why, as a rule, we should be sacrificed to our own emotions. Is it not, on the whole, desirable that women should study facts and weigh rea- sons as men do ? You may say that it is the emotional virtues which are distinctively feminine, and that, as Mr. Allen says, 1 a woman's glory is to be womanly, as a man's is to be virile ' ; but can it be shown that the training of her intellect makes a woman any less capable of love and devotion ? Does it make her any less willing to sacrifice herself for the good of others ? I think, on the contrary, that there is abundant witness to the fact that the increase of a woman's intellectual power usually intensifies her susceptibility to high motives, from whatever source they may reach her, or through whatever channel they may come. But, certainly, she is no longer a passive recipient ; 6o4 THE POPULAR SCIENCE MONTHLY. she thinks now as well as feels, and the inevitable result is that her attitude is more judicial than of old." " Do you know," here interpolates a newly graduated col- legian, " that in our colleges it has become a proverb that, if a girl isn't engaged before she is a sophomore, the chances are all against her marriage ? " The assent to this is very general, and one of the older women states the evident reasons for it : " We become more interested in our studies, more certain of our ability to take care of ourselves, and therefore less interested in men as possible lovers, and more independent of them as a means of support." " And also," dryly remarks a very marriageable maiden, " it becomes evident to us that, as a matter of fact, the men whom our friends marry do not always come to time in their role of ' providers/ and are not infrequently ready to accept assistance at the hands of the women whom they have undertaken to support." Apropos of this, it is here suggested that possibly the prospect of domestic drudgery is not congenial to women who have found themselves capable of different and better work ; and this is assented to by several of those present who are supporting their own establishments, and paying servants to perform the house- hold labor which would fall upon their shoulders were they in the position of the married woman of average means. This, again, suggests a comparison as to the relative value of the normal home wherein father, mother, and children complete the group, and of those more artificial homes which lack the nat- ural elements of union. Generous recognition is at once given of the beauty of the possible home, and of the power and importance of the woman who creates it ; but that this is woman's only field is emphatically denied. There are now open to her many channels through which she can influence the race, and the question is raised as to whether the advantage in this respect is altogether on the side of the married woman. Two or three of the older women in the group, who have had long and varied experience as teachers, ask if it is not probable that among the many children who have come into their hands there are not some, at least, who owe more to their school environment than to the home life. They claim that they, as teachers, should be credited with the influence which, in the nature of things, is inseparable from the respon- sibility which is put upon them. " To us," they say, " and not to the already overburdened wife and mother, is given the power to lead and direct the youth of the race. Would you have us, with that in view, aim for anything less than the best ? The education of English and American children is, in the main, in the hands of women, and this not because of an anomalous social condition, but because of their peculiar fitness for the work. On Mr. Allen's THE MISSION OF EDUCATED WOMEN. 605 own showing, these women should remain unmarried, and, if this involves a sacrifice on their part, it is left for him to show us that such sacrifice is ignoble, or in any sense threatening to the public welfare." A response to this comes from the women physicians, who, in their work for their own sex and for children, feel, in all humility, that they are doing more for humanity than if they limited them- selves to the reproduction of their kind. Granting that each of these women might leave behind her the ideal four successors, what is this in comparison with the many women whom she may have saved from disease and death ; the households to which she has taught better ways ; the new standards of purity and self- restraint for which she has bravely fought ? In such a discussion it is difficult not to individualize ; but, well as I know these women, I am surprised at the breadth of their views, their candor, and their humility in regard to their own achievements. But it is a humility which permits no abate- ment of their just claims. They no longer admit any question as to their intellectual capacity. With the simplicity of conscious strength they take their place beside the men who challenge them, and are not at all afraid to face the result of their own actions. It is also plain that they are, on the whole, contented with the lot which they have chosen. The sacrifice, if it be such, has been made with open eyes and of free will, and there is no sighing after the possibilities which they have rejected. " But," I ask, " do you never feel, especially as you grow older, the lack of some young strength upon which to lean, some fresh energy to which to bequeath your own experience ? " As might be expected, the answer to this is varied. In some instances the strength of the maternal instinct has led to the adoption of children ; in others, to some special work which keeps up the connection with childhood ; while again there are women, as there are men, in whom the instinct is lacking, and who find other interests sufficient to fill the gap. Mr. Allen's suggestion as to the possible readjustment of the marriage relation, and his pledge that men will meet women half- way in any such attempt, is received without special enthusiasm. That is, the general feeling is, that it is not in the marriage rela- tion, either in its legal or social aspect, that the root of the diffi- culty is to be found. Rather, they consider, it must be looked for in the standards with which men and women enter into that rela- tion. It is constantly proved, by the evidence of happy marriages, that the contract easily adjusts itself where the parties to it com- prehend and accept its terms. Not that there is not room for improvement in minor particulars, especially in the direction of certain legislative changes ; but that, fundamentally, the monoga- 606 THE POPULAR SCIENCE MONTHLY. mous idea, the permanent union of one woman with, one man, is a trustworthy basis upon which to rest the social structure. The women of whom I am writing disclaim positively that their indifference as to marriage arises from any dissatisfaction with the institution as it now and here exists. They deny also unanimously, and backed by a good deal of proof, that their education (it being understood that they have received the mod- ern college education, or its equivalent) in any way unfits them for the duties of wifehood and maternity, or, primarily, renders these conditions any less attractive to them than to the " domes- tic " type of women. On the contrary, they hold that their knowl- edge of physiology makes them better mothers and housekeepers ; their knowledge of chemistry makes them better cooks; while, from their training in other natural sciences and in mathematics, they obtain an accuracy and fair-mindedness which is of great value to them in dealing with their children or their employe's. In short, they are not afraid to match themselves in practical life with the women for whom Mr. Allen claims a development im- possible to the " dulled and spiritless epicene automata " to whom his attack is addressed. As we approach the close of the discussion, the common sense of the various speakers makes itself strongly felt. They are not theorists, but practical, healthy women, and they do not in the least deceive themselves as to the actual, every-day aspect of this question. But, on the other hand, they stand for the feminine type of which our American prophet and seer wrote thirty years ago : * " At this moment I esteem it a chief felicity of this country that it excels in women. A certain awkward consciousness of inferi- ority in the men may give rise to the new chivalry in behalf of * woman's rights.' Certainly, let her be as much better placed in the laws and in social forms as the most zealous reformer can ask ; but I confide so entirely in her inspiring and musical nature that I believe only herself can show us how she shall be served. The wonderful generosity of her sentiments raises her at times into heroical and godlike regions, and verifies the pictures of Minerva, Juno, or Polymnia ; and, by the firmness with which she treads her upward path, she convinces the coarsest calculators that another road exists than that which their feet know." And it is therefore no surprise to find that these women of a later gen- eration are, finally, by the loftiness of their ideas and, as it were, in spite of themselves, lifted above the plane of Mr. Allen's argu- ments. They sum up the reasons why they, as individuals, do not marry, in a somewhat formidable array. " We find," they say, " that we are intellectually the equals of the men whom we meet. * Emerson, " Essay on Manners." THE MISSION OF EDUCATED WOMEN. 607 It is now a fair give and take, and it is no longer required of us that we niake up for the light weight of our intellects by throw- ing in a double measure of sentiment. Neither is it any longer necessary that we marry for the sake of a somewhat uncertain support. We are able to take care of ourselves, and we find nothing uncongenial or unsexing in our success. " Furthermore, and above all, we see that, while the processes of evolution have pushed us so far forward that there is no longer, in our dealings with men, any serious question as to infe- rior or superior abilities, there still remains between our moral standards and theirs the same gap that has existed ever since the purity of woman has been tacitly recognized as essential to civi- lization. " The moral sense is, in us, more highly developed than in the men who are otherwise our peers ; and now that this is no longer deflected in its action by the pressure of unfair conditions, it is equivalent to a new factor in the relation of the sexes. It is evi- dent, however, that this factor can not have full play except as the individual is independent ; and it is to the single, self-support- ing woman only that this independence is possible. Women who are dependent, in any direction, upon men, must, almost of neces- sity, condone their vices, and as a result gradually approximate to their standards, which is a consummation most devoutly not to be desired. We believe that there is no personal conceit in claim- ing that we are morally upon a higher level than men, this being a recognized fact in modern sociology; but it is a fact which repels us from the close relations of marriage, in which we now believe that we have a right to a return for all that we give. When, therefore, we find that, while we are offered intellectual companionship and provision for our physical needs, the higher demands of our spiritual nature are ignored or set aside, we natu- rally hesitate, and hesitating are, from Mr. Allen's point of view, lost. He looks at our problem from without, we from within. We realize, often in bitterness of heart, that our moral life, the life of our aspirations, is upon a plane which, as yet, the average man has not reached. We can never go back to him, but we stand ready to welcome him whenever he can bridge the chasm and make our standard his. " This is our position as individuals ; as a class we see no evi- dence that we are ' accidents/ still less that we are to be deplored. We believe indeed that, so far from this being true, we in reality represent an important phase in human development, that we are a distinct product of evolutionary forces, and that in the future it is not impossible that the ' balance of power ' may be found to lie in our hands." The value of this statement is in the fact that it comes not 608 THE POPULAR SCIENCE MONTHLY. from one woman but from many, and in it there is surely nothing to discourage Mr. Allen and those who think with him. The women to whom he appeals are ready to meet him, but it must be on a platform of their own choosing, and they can afford to wait. They do not ask " aid in rebelling against maternity," but they demand that the responsibilities of fatherhood shall no longer be shifted or made light of. In short, they require of the fathers of the next generation just what Mr. Allen demands for the mothers, viz., " that they shall be as strong, as wise, as pure, as sane, as healthy, as earnest, and as efficient as they can be made." And as this demand, on the part at least of the men who make it, is presumably based not so much on any personal predilection for the qualities enumerated as upon their desire to further the best interests of the race, the argument in its favor is as valid for the one sex as for the other. -♦••►-♦- ABSOLUTE POLITICAL ETHICS. By HERBERT SPENCER. LIFE in Fiji at the time when Thomas Williams settled there must have been something worse than uncomfortable. One of the people who passed near the string of nine hundred stones with which Ra Undreundre recorded the number of human vic- tims he had devoured, must have had unpleasant waking thoughts and occasionally horrible dreams. A man who had lost some fingers for breaches of ceremony, or had seen his neighbor killed by a chief for behavior not sufficiently respectful, and who re- membered how King Tanoa cut off his cousin's arm, cooked it and ate it in his presence, and then had him cut to pieces, must not unfrequently have had "a, bad quarter of an hour." Nor could creeping sensations have failed to run through any women who heard Tui Thakan eulogizing his dead son for cruelty, and saying that " he could kill his own wives if they offended him, and eat them afterward." Happiness could not have been general in a society where there was a liability to be one among the ten whose life-blood baptized the decks of a new canoe— a society in which the killing even of unoffending persons was no crime but a glory ; and in which every one knew that his neighbor's restless ambition was to be an acknowledged murderer. Still there must have been some moderation in murdering even in Fiji. Or must we hesitate to conclude that unlimited murder would have caused extinction of the society ? The extent to which each man's possessions among the Biluchis are endangered by the predatory instincts of his neighbors, may ABSOLUTE POLITICAL ETHICS. 609 be judged from the fact that " a small mud tower is erected in each field, where the possessor and his retainers guard his produce." If turbulent states of society such as early histories tell of, do not show us so vividly how the habit of appropriating one another's goods interferes with social prosperity and individual comfort, yet they do not leave us in doubt respecting these results. It is an inference which few will be hardy enough to dispute, that in proportion as the time of each man, instead of being occupied in further production, is occupied in guarding that which he has produced against marauders, the total production must be di- minished and the sustentation of each and all less satisfactorily achieved. And it is a manifest corollary that if each pushes be- yond a certain limit the practice of trying to satisfy his needs by robbing his neighbor, the society must dissolve : solitary life will prove preferable. A deceased friend of mine, narrating incidents in his life, told me that as a young man he sought to establish himself in Spain as a commission agent ; and that, failing by expostulation or other means to obtain payment from one who had ordered goods through him, he, as a last resource, went to the man's house and presented himself before him pistol in hand — a proceeding which had the desired effect : the account was settled. Suppose now that every- where contracts had thus to be enforced by more or less strenuous measures. Suppose that a coal-mine proprietor in Derbyshire, having sent a train-load to a London coal-merchant, had com- monly to send a posse of colliers up to town, to stop the man's wagons and take out the horses until payment had been made. Suppose the farm laborer or the artisan was constantly in doubt whether, at the end of the week, the wages agreed upon would be forthcoming, or whether he would get only half, or whether he would have to wait six months. Suppose that daily in every shop there occurred scuffles between shopman and customer, the one to get the money without giving the goods, and the other to get the goods without paying the money. What in such case would hap- pen to the society ? What would become of its producing and distributing businesses ? Is it a rash inference that industrial co-operation (of the voluntary kind at least) would cease ? " Why these absurd questions ? " asks the impatient reader. " Surely every one knows that murder, assault, robbery, fraud, breach of contract, etc., are at variance with social welfare and must be punished when committed." My replies are several. In the first place, I am quite content to have the questions called ab- surd ; because this implies a consciousness that the answers are so self-evident that it is absurd to assume the possibility of any other answers. My second reply is that I am not desirous of pressing the question whether we know these things, but of pressing the VOL. XXXVI. — 39 610 THE POPULAR SCIENCE MONTHLY. question how we know these things. Can we know them, and do we know them, by contemplating the necessities of the case ? or must we have recourse to " inductions based on careful observa- tion and experience " ? Before we make and enforce laws against murder, ought we to inquire into the social welfare and individual happiness in places where murder prevails, and observe whether or not the welfare and happiness are greater in places where mur- der is rare ? Shall robbery be allowed to go on until, by collecting and tabulating the effects in countries where thieves predominate and in countries where thieves are but few, we are shown by induc- tion that prosperity is greater when each man is allowed to retain that which he has earned ? And is it needful to prove by accu- mulated evidence that breaches of contract impede production and exchange, and those benefits to each and all which mutual depend- ence achieves ? In the third place, these instances of actions which, pushed to extremes, cause social dissolution, and which, in smaller degrees, hinder social co-operation and its benefits, I give for the purpose of asking what is their common trait. In each of such actions we see aggression — a carrying on of life in a way which di- rectly interferes with the carrying on of another's life. The rela- tion between effort and consequent benefit in one man, is either destroyed altogether or partially broken by the doings of another man. If it be admitted that life can be maintained only by certain activities (the internal ones being universal, and the external ones being universal for all but parasites and the immature), it must be admitted that when like-natured beings are associated, the re- quired activities must be mutually limited ; and that the highest life can result only when the associated beings are so constituted as severally to keep within the implied limits. The restrictions stated thus generally, may obviously be developed into special restrictions referring to this or that kind of conduct. These, then, I hold are a priori truths which admit of being known by contem- plation of the conditions — axiomatic truths which bear to ethics a relation analogous to that which the mathematical axioms bear to the exact sciences. I do not mean that these axiomatic truths are cognizable by all. For the apprehension of them, as for the apprehension of simpler axioms, a certain mental growth and a certain mental dis- cipline are needed. In the " Treatise on Natural Philosophy " by Profs. Thomson and Tait, it is remarked that " physical axioms are axiomatic to those only who have sufficient knowledge of the action of physical causes to enable them to see at once their neces- sary truth." Doubtless a fact and a significant fact. A plow-boy can not form a conception of the axiom that action and reaction are equal and opposite. In the first place he lacks a sufficiently generalized idea of action — has not united into one conception ABSOLUTE POLITICAL ETHICS. 611 pushing and pulling, the blow of a fist, the recoil of a gun, and the attraction of a planet. Still less has he any generalized idea of reaction. And even had he these two ideas, it is probable that, defective in power of representation as he is, he would fail to recognize the necessary equality. Similarly with these a priori ethical truths. If a speculative member of that Fijian slave-tribe who regarded themselves as food for the chiefs had suggested that there might come a place where men would not eat one another, his implied belief that they might come to have a little respect for one another's lives, condemned as utterly without justification in experience, would be considered as fit only for a wild speculator. Facts furnished by every-day observation make it clear to the Biluchi, keeping watch in his mud tower, that possession of prop- erty can be maintained only by force ; and it is most likely to him scarcely conceivable that there exist limits which, if mutually rec- ognized, may exclude aggressions, and make it needless to mount guard over fields : only an absurd idealist (supposing such a thing known to him) would suggest the possibility. And so even of our own ancestors in feudal times, it may be concluded that, constantly going about armed and often taking refuge in strongholds, the thought of a peaceful social state would have seemed ridiculous ; and the belief that there might be a recognized equality among men's claims to pursue the objects of life, and a consequent desist- ence from aggressions, would have been scarcely conceivable. But now that an orderly social state has been maintained for genera- tions— now that in daily intercourse men rarely use violence, com- monly pay what they owe, and in most cases respect the claims of the weak as well as those of the strong — now that they are brought up with the idea that all men are equal before the law, and daily see judicial decisions turning upon the question whether one citi- zen has or has not infringed upon the equal rights of another ; there exist in the general mind materials for forming the concep- tion of a regime in which men's activities are mutually limited, and in which maintenance of harmony depends on respect for the limits. There has arisen an ability to see that mutual limitations are necessitated when lives are carried on in proximity ; and to see that there necessarily emerge definite sets of restraints applying to definite classes of actions. And it has become manifest to some, though not it seems to many, that there results an a priori system of absolute political ethics — a system under which men of like natures, severally so constituted as spontaneously to refrain from trespassing, may work together without friction, and with the greatest advantage to each and all. " But men are not wholly like-natured and are unlikely to be- come so. Nor are they so constituted that each is solicitous for his neighbor's claims as for his own, and there is small probability 612 THE POPULAR SCIENCE MONTHLY. that they ever will be. Your absolute political ethics is therefore an ideal beyond the reach of the real." This is quite true. Never- theless, much as it seems to do so, it does not in the least follow that there is no use for absolute political ethics. The contrary may clearly enough be shown. An analogy will explain the paradox. There exists a division of physical science distinguished as abstract mechanics or absolute mechanics — absolute in the sense that its propositions are unqualified. It is concerned with statics and dynamics in their pure forms — deals with forces and motions considered as free from all interferences resulting from friction, resistances of media, and special properties of matter. If it enun- ciates a law of motion, it recognizes nothing which modifies mani- festation of it. If it formulates the properties of the lever it treats of this assuming it to be perfectly rigid and without thickness — an impossible lever. Its theory of the screw imagines the screw to be frictionless ; and in treating of the wedge, absolute incom- pressibility is supposed. Thus its truths are never presented in experience. Even those movements of the heavenly bodies which are deducible from its propositions are always more or less per- turbed ; and on the Earth the inferences to be drawn from them deviate very considerably from the results reached by experiment. Nevertheless this system of ideal mechanics is indispensable for the guidance of real mechanics. The engineer has to deal with its propositions as true in full, before he proceeds to qualify them by taking into account the natures of the materials he uses. The course which a projectile would take if subject only to the pro- pulsive force and the attraction of the Earth must be recognized, though no such course is ever pursued : correction for atmospheric resistance can not else be made. That is to say, though, by em- pirical methods, applied or relative mechanics may be developed to a considerable extent, it can not be highly developed without the aid of absolute mechanics. So is it here. Relative political ethics, or that which deals with right and wrong in public affairs as partially determined by changing circumstances, can not pro- gress without taking into account right and wrong considered apart from changing circumstances — can not do without absolute political ethics; the propositions of which, deduced from the con- ditions under which life is carried on in an associated state, take no account of the special circumstances of any particular asso- ciated state. And now observe a truth which seems entirely overlooked : namely, that the set of deductions thus arrived at is verified by an immeasurably vast induction, or rather by a great assemblage of vast inductions. For what else are the laws and judicial sys- tems of all civilized nations, and of all societies which have risen above savagery ? What is the meaning of the fact that all ABSOLUTE POLITICAL ETHICS. 613 peoples have discovered the need for punishing murder, usually by death ? How is it that where any considerable progress has been made, theft is forbidden by law, and a penalty attached to it ? Why along with further advance does the enforcing of con- tracts become general ? And what is the reason that among fully civilized peoples frauds, libels, and minor aggressions of various kinds are repressed in more or less rigorous ways ? No cause can be assigned save a general uniformity in men's experiences, showing them that aggressions directly injurious to the indi- viduals aggressed upon are indirectly injurious to society. Gen- eration after generation observations have forced this truth on them ; and generation after generation they have been developing the interdicts into greater detail. That is to say, the above fun- damental principle and its corollaries arrived at a priori are veri- fied in an infinity of cases a posteriori. Everywhere the tendency has been to carry further in practice the dictates of theory — to conform systems of law to the requirements of absolute political ethics: if not consciously, still unconsciously. Nay, indeed, is not this truth manifest in the very name used for the end aimed at — equity or equalness ? Equalness of what ? No answer can be given without a recognition — vague it may be, but still a rec- ognition— of the doctrine above set forth. Thus, instead of being described as putting faith in "long chains of deduction from abstract ethical assumptions " I ought to be described as putting faith in simple deductions from abstract ethical necessities; which deductions are verified by infinitely numerous observations and experiences of semi-civilized and civi- lized mankind in all ages and places. Or rather I ought to be de- scribed as one who, contemplating the restraints everywhere put upon the, various kinds of transgressions, and seeing in them all a common principle everywhere dictated by the necessities of the associated state, proceeds to develop the consequences of this common principle by deduction, and to justify both the deduc- tions and the conclusions which legislators have empirically reached by showing that the two correspond. This method of deduction verified by induction is the method of developed sci- ence at large. I do not believe that I shall be led to abandon it and change my "way of thinking" by any amount of disap- proval, however strongly expressed. Are we then to understand that by this imposing title, " Abso- lute Political Ethics," nothing more is meant than a theory of the needful restraints which law imposes on the actions of citizens — an ethical warrant for systems of law ? Well, supposing even that I had to answer " Yes " to this question (which I do not), there would still be an ample justification for the title. Having for its subject-matter all that is comprehended under the word 6i4 THE POPULAR SCIENCE MONTHLY. " Justice/' alike as formulated in law and administered by legal instrumentalities, the title has a sufficiently large area to cover. This would scarcely need saying were it not for a curious defect of thought which we are everywhere led into by habit. Just as, when talking of knowledge, we ignore entirely that familiar knowledge of surrounding things, animate and inani- mate, acquired in childhood, in the absence of which death would quickly result, and think only of that far less essential knowl- edge gained at school and college or from books and conversation — just as, when thinking of mathematics, we include under the name only its higher groups of truths and drop out that simpler group constituting arithmetic, though for the carrying on of life this is more important than all the rest put together ; so, when politics and political ethics are discussed, there is no thought of those parts of them which include whatever is fundamental and long settled. The word political raises ideas of party-contests, ministerial changes, prospective elections, or else of the Home- Rule question, the Land-Purchase scheme, Local Option, or the Eight-Hours movement. Rarely does the word suggest law-re- form, or a better judicial organization, or a purified police. And if ethics comes into consideration, it is in connection with the morals of parliamentary strife or of candidates' professions, or of electoral corruptions. Yet it needs but to look at the definition of politics (" that part of ethics which consists in the regulation and government of a nation or state, for the preservation of its safety, peace, and prosperity "), to see that the current conception fails by omitting the chief part. It needs but to consider how relatively immense a factor in the life of each man is constituted by safety of person, security of house and property, and enforce- ment of claims, to see that not only the largest part but the part which is vital is left out. Hence the absurdity does not exist in the conception of an absolute political ethics, but it exists in the ignoring of its subject-matter. Unless it be considered absurd to regard as absolute the interdicts against murder, burglary, fraud, and all other aggressions, it can not be considered absurd to re- gard as absolute the ethical system which embodies these in- terdicts. It remains to add that beyond the deductions which, as we have seen, are verified by vast assemblages of inductions, there may be drawn other deductions not thus verified — deductions drawn from the same data, but which have no relevant experi- ences to say yes or no to them. Such deductions may be valid or invalid ; and I believe that in my first work, written forty years ago and long since withdrawn from circulation, there are some invalid deductions. But to reject a principle and a method be- cause of some invalid deductions is about as proper as it would ABSOLUTE POLITICAL ETHICS. 615 be to pooh-pooh arithmetic because of blunders in certain arith- metical calculations. I turn now to a question above put — whether, by absolute political ethics, nothing more is meant than an ethical warrant for systems of law — a question to which, by implication, I an- swered No. And now I have to answer that it extends over a further field equally wide if less important. For beyond the rela- tions among citizens taken individually, there are the relations between the incorporated body of citizens and each citizen. And on these relations between the State and the man, absolute politi- cal ethics gives judgments as well as on the relations between man and man. Its judgments on the relations between man and man are corollaries from its primary truth, that the activities of each in pursuing the objects of life may be rightly restricted only by the like activities of others : such others being like-natured (for the principle does not contemplate slave-societies or societies in which one race dominates over another) ; and its judgments on the relations between the man and the State are corollaries from the allied truth, that the activities of each citizen may be rightly limited by the incorporated body of citizens only as far as is needful for securing to him the remainder. This further limitation is a necessary accompaniment of the militant state; and must continue so long as, besides the criminalities of indi- vidual aggression, there continue the criminalities of international aggression. It is clear that the preservation of the society is an end which must take precedence of the preservation of its indi- viduals taken singly; since the preservation of each individual and maintenance of his ability to pursue the objects of life, de- pend on the preservation of the society. Such restrictions upon his actions as are imposed by the necessities of war, and of pre- paredness for war when it is probable, are therefore ethically de- fensible. And here we enter upon the many and involved questions with which relative political ethics has to deal. When originally indicating the contrast, I spoke of " absolute political ethics, or that which ought to be, as distinguished from relative political ethics, or that which is at present the nearest practicable approach to it " ; and had any ' attention been paid to this distinction, no controversy need have arisen. Here I have to add that the quali- fications which relative political ethics sets forth vary with the type of the society, which is primarily determined by the extent to which defense against other societies is needful. Where inter- national enmity is great and the social organization has to be adapted to warlike activities, the coercion of individuals by the State is such as almost to destroy their freedom of action and 616 THE POPULAR SCIENCE MONTHLY. make them slaves of the State ; and where this results from the necessities of defensive war (not offensive war, however), relative political ethics furnishes a warrant. Conversely, as militancy decreases, there is a diminished need both for that subordination of the individuals which is necessitated by consolidating them into a fighting machine, and for that further subordination en- tailed by supplying this fighting machine with the necessaries of life ; and as fast as this change goes on, the warrant for State - coercion which relative political ethics furnishes becomes less and less. Obviously it is out of the question here to enter upon the com- plex questions raised. It must suffice to indicate them as above. Should I be able to complete Part IV of the "Principles of Ethics" treating of "Justice," of which the first chapters only are at present written, I hope to deal adequately with these rela- tions between the ethics of the progressive condition and the ethics of that condition which is the goal of progress — a goal ever to be recognized, though it can not be actually reached. The grave misrepresentations dealt with in the foregoing sec- tions, I have been able to rectify by an exposition that is mainly impersonal : allusions, only, having been made to the personal bearings of the argument. But there remain other grave misrep- resentations which I can not dispose of in the same way. Life sometimes presents alternatives both of which are disagreeable, and acceptance of either of which is damaging. A choice between two such I now find myself compelled to make. Prof. Huxley, referring to me, speaks of "the gulf fixed between his way of thinking and mine " : the implication being that as he regards his own " way of thinking " as the right one, my way of thinking, separated from it by a gulf, must be extremely wrong. As this tacit condemnation of my " way of thinking " touches not only the question at issue but also many other questions, and as it comes not from an anonymous critic, but from one whose state- ments will be taken as trustworthy, I am placed in the dilemma of either passively allowing his injurious characterization, or else of showing that it is untrue, which I can not do without describ- ing or illustrating my " way of thinking." This is, of course, an unpleasant undertaking, and one which self-respect would ordi- narily negative. But unpleasant as it is, I feel obliged to enter upon it. Years ago Prof. Huxley criticised the political doctrine held by me, and entitled his article " Administrative Nihilism." As this doctrine includes advocacy of governmental action for the repression not only of crimes but of many minor offenses, I pointed out that if it is to be called " administrative nihilism," then still ABSOLUTE POLITICAL ETHICS. 617 more must the eight prohibitory clauses of the decalogue be called ethical nihilism. Prof. Huxley nevertheless thought his title a fit one; and has continued to use it in the last edition of his " Critiques and Addresses." This political doctrine held by me remains unchanged, but the view taken of it by Prof. Huxley appears to have been reversed. In an emphatic manner he has recently warned me against " undertaking to preserve the health and heal the diseases of an organism vastly more complicated than the human body/' having for my guides "long chains of deduction from abstract ethical assumptions." So that while represented as one who would have no administration at all, I am represented as advocating dangerous administrative methods of healing diseases of the body politic. My policy is characterized now as a policy of no action, and now as a policy of rash action. These two characterizations are applied to the same set of beliefs, and they stand in direct contradiction. Necessarily there must be extreme error in one or both ; and the latter alternative is the true one : both are wrong. The " way of thinking " which Prof. Huxley indicates as sep- arated by a gulf from his own, and which he implies is exclusively pursued by me, is that of reaching conclusions by " long chains of deduction from abstract ethical assumptions, hardly any link of which can be tested experimentally." On the other hand the course he advocates is that of seeking guidance from " inductions based on careful observation and experience" — a course which he implies is not pursued by me, either in the political sphere or elsewhere ; certainly not in the political sphere. Now let us ask what is implied by the evidence. Up to the end of the division treating of Ecclesiastical Institutions, where it has stood still for these four years, the "Principles of Sociology" contains more than five thousand facts, gathered from accounts of more than two hundred societies, savage and civilized, ancient and modern. If, then, I am rightly described as pursuing the deductive method (exclusively, as it would appear), there arises this curious ques- tion : — How have I used for deductive purposes more facts than have been used by any other writer on Sociology for inductive purposes ? " This is irrelevant," will perhaps be the rejoinder — " the question concerns not the method pursued in dealing with Sociology at large, but the method pursued in dealing with govern- mental actions at the present time." Merely remarking that it would be strange had I pursued one method in treating the sub- ject at large and an opposite method in treating a small division of it, I go on to reply that I have not pursued the opposite method but the same method. The views I hold respecting the sphere of governmental action are everywhere supported by inductions. The essay on " Over-Legislation," dating back to 1853, is almost 618 THE POPULAR SCIENCE MONTHLY. wholly inductive. Inductive reasoning in support of the same views occupies the greater part of the essay on " Representative Government," much of the essay on " Parliamentary Reform : the Dangers and the Safeguards," and half of the essay on " Special- ized Administration." In the " Study of Sociology," again, several masses of facts are brought in support of the same views (pp. 3, 4, 161-1G9, and 270-273) ; and once more in " The Man versus the State" (pp. 48-60 and 62-64) a like course is pursued. I count, in different places, eight inductive arguments, not in defense of proposals for curing the diseases of the body politic, but in repro- bation of proposals for doing this. " But do not the books and essays named contain deductive arguments ? " it may be asked. Certainly they do ; and I should be ashamed of them if they did not. But everywhere there has been pursued what I have above said is the method of developed science — deduction verified by induction. I shall think it time to reconsider the deductions when I find the masses of facts which support them met by larger masses of facts which do the reverse. " Careful observa- tion and experience " have not yet furnished these. To make clear the use of an ideal for guidance in dealing with the real, I had recourse to the familiar comparison between the individual body and the body politic. I remarked that " before there can be rational treatment of a disordered state of the bodily functions, there must be a conception of what constitutes their ordered state." The guidance contemplated as derivable from such knowledge consists in exclusion of what is wrong to be done, not in directions concerning what is right to be done. This is clearly shown by the context. There is an imaginary warning against the excesses of a supposed empiric as being " at variance with physi- ological principles " ; that is, negatived by them or forbidden by them. There is no trace whatever of any proposed treatment conforming to physiological principles, but merely an interdict against a treatment. Yet on the strength of these passages, Prof. Huxley ascribes to me the monstrous belief that the practitioner should " treat his patients by deduction from physiological prin- ciples " ! Similarly with the body politic. While I have alleged that " a system of limits and restraints on conduct " may be de- duced from the primary conditions of social co-operation, Prof. Huxley represents me as proposing to seek guidance in healing " the diseases of an organism vastly more complicated than the human body " by " deduction from abstract ethical assumptions ! " "While in both cases the guiding inferences indicated by me all come under the blank form — " Thou shalt not do this," they are rep- resented as coming under the blank form — " Thou shalt do that." How utterly at variance is the view thus ascribed to me with the view I have myself expressed, will be seen in the following passage : ABSOLUTE POLITICAL ETHICS. 619 How, indeed, can any man, and how more especially can any man of scientific culture, think that special results of special political acts can be calculated, when he contemplates the incalculable complexity of the influences under which each individual, and a fortiori each society, develops, lives, and decays? . . . As fast as crude conceptions of diseases and remedial measures grow up into Pathology and Therapeutics, we find increasing caution, along with increasing proof that evil is often done instead of good. This contrast is traceable not only as we pass from popular ignorance to professional knowledge, but as we pass from the smaller professional knowledge of early times to the greater professional knowledge of our own. The question with the modern physician is not as with the ancient— shall the treatment be blood- letting? shall cathartics, or shall dia- phoretics be given ? or shall mercurials be administered ? But there rises the previous question — shall there be any treatment beyond a wholesome regimen ? And even among existing physicians it happens that, in proportion as the judg- ment is most cultivated, there is the least yielding to the " must-do-something " impulse. Is it not possible, then — is it not even probable, that this supposed necessity for immediate action, which is put in as an excuse for drawing quick conclusions from few data, is the concomitant of deficient knowledge ? Is it not probable that as in Biology so in Sociology, the accumulation of more facts, the more critical comparison of them, and the drawing of conclusions on scientific methods, will be accompanied by increasing doubt about the benefits to be secured, and increasing fear of the mischiefs which may be worked ? Is it not probable that what in the individual organism is improperly, though conveniently, called the vis medicatrix natures, may be found to have its analogue in the social organism ? and will there not very likely come along with the recognition of this, the consciousness that in both cases the one thing needful is to maintain the conditions under which the natural actions have fair play? — The Study of Sociology, pp. 15-21. Manifestly if, instead of saying that I proposed to treat the diseases of this complex social organism by the aid of deductions from " abstract ethical assumptions," Prof. Huxley had, contrari- wise, said that I am so over-cautious that I dare not treat them at all, save by maintaining the conditions to health, he would have had ground for his statement. As early as 1853 (" Over-Legisla- tion," pp. 62, 63) I dwelt on the involved structure of a society and the consequent difficulty and danger of dealing with it. Since then I have more than once insisted on these facts. And now that which I have been teaching for a generation is put before me «as a lesson to be learned ! Replies will, I suppose, be made to some of the things said in the foregoing pages. Always there are collateral questions on which debates may be raised. I see, for instance, that one of my remarks may have given to it a meaning quite different to that which I intended. After the ascription to me of the belief that treatment of diseases should be dictated by physiological princi- ples, rightly enough regarded by Prof. Huxley as absurd, there came from me the remark that, according to him, " the principles of physiology, as at present known, are of no use whatever for 62o THE POPULAR SCIENCE MONTHLY. guidance in practice " — a remark which may be interpreted as a tacit indorsement of the ascription ; whereas it referred to the fact that he had recognized for the present (though not for the future) no guidance whatever beyond that of empiricism. Doubtless there may be other side-issues which I do not perceive. But no number of such can change the verdicts on the main issues. That Prof. Huxley's two characterizations of the political doctrine I hold are contradictory, is undeniable. That his description of my " way of thinking " is utterly at variance with the evidence as presented in my books, is no less demonstrated. And it is equally certain that the conceptions of right treatment, medical and political, which he ascribes to me are opposite to those I have myself set forth. — Nineteenth Century. ♦♦♦ THE LAWS OF FILMS. By SOPHIE BLEDSOE HEREICK. THERE is scarcely anything in the world which seems more utterly outside the realm of law than a soap-bubble. The delicate film, with its exquisite floating colors, its power of instant- ly vanishing, leaving no trace behind, hardly seems as though it could form a link in the inexorable chain of cause and effect which we call physical law. The atmospheric pressure on a bubble six inches in diameter is over fifteen hundred pounds, and yet the fragile film lies safely between the opposing forces of nature — the pressure of the outer air, the spring of the inclosed cushion within it, the downward pull of gravity, the upward push of the buoyant atmosphere, and the molecular forces in the film itself : so long as the bubble lasts ; it is because of an exquisite adjustment of all the forces, physical and molecular, concerned in its existence. This is, of course, the merest commonplace, and yet it is one of the commonplaces of nature, which, however well we may know them, never cease to be wonderful when they are in any degree realized. There are other laws governing films which are no less wonderful, though they are less familiarly known. A heap of bubbles blown while the pipe is dipped under the surface of soapy water looks like a chaotic huddle of bubbles of all sizes and many shapes ; but, upon careful examination, it is found that never more than three films meet at an unsupported liquid edge, and never more than four edges meet at a liquid point, and that the angles are always equal ; that is, films will not meet each other at an un- supported edge or point at an angle smaller than 120° — one third of a circle. Ordinary soap-suds made with clean hot water and ivory or THE LAWS OF FILMS. 621 pure Castile soap, and allowed to settle and clarify, or else filtered, answer very well for a series of simple and beautiful experiments in the forms assumed by soap films in order to fulfill this law of their union. There is a glyceric fluid made, which by various means has all the impurities of soap and water removed, and is toughened by the addition of pure glycerin ; and this is of course better, because much more persistent. A bubble made from this glyceric fluid, and carefully protected by a tumbler or bell-glass, will last for hours, and in some cases for days. For these experiments in form, common suds last long enough to show the forms very satisfactorily, but for experiment in color the more lasting fluid is necessary, so a recipe for it is given here.* When frames made in various forms, by bending fine copper wire, are dipped into the fluid, it is found that the films take on the most wonderful and beautiful shapes in order to fulfill the law of their union. The material of which the films are made does not at all affect their form. With fine, well-straightened copper wire, outline a cube ; this may be done with the fingers or a pair of ordinary pliers, and the figure need not be very exact. The wires can be double along any of the lines ; let one end project from some corner for a handle, to be used in dipping the frame into the fluid. Immerse this cube in the suds, and as you lift the frame out observe the films forming and shaping themselves. They usually take for a moment the form in Fig. 1 and slowly change to Fig. 2. Sometimes they retain the first form; in this case, the central drop with a glass of low power is seen to be not really a drop of fluid, but a tiny cube of films, each meeting the film from the wire edge by a curvature of its faces at exactly the required angle, 120°. The films have constructed in their midst this tiny cube, because the twelve films could not otherwise meet in the center at the proper angle. This cube is formed and kept where a tiny bubble has been entrapped in the system of films. If no such bubble of air has been caught in with the films, they * Plateau's mixture. This must be made in a warm room, temperature about 68° Fahr. Let one half ounce of newly made Marseilles or pure Castile soap be dissolved in one pint (twenty ounces) of hot distilled water. When the solution has cooled to about the tem- perature of the room, it is filtered into a bottle. In using the common filter paper (bought at a drug-store for ten cents a dozen sheets), it is better to put only a small quantity of the mixture in at a time, and to support the paper in a funnel or muslin to prevent its break- ing. The paper soon clogs ; it should then be renewed. The process is slow, but not troublesome. When it has all been filtered, add fifteen ounces of pure glycerin — either Price's or Scheering and Glatz's — the ordinary glycerins are not fit for the purpose. Let the mixture be violently and frequently shaken ; then allow it to stand seven days ; on the eighth cool it to about 37° Fahr., and filter. If the liquid comes through turbid, pour it back and filter over again through very porous paper. 622 THE POPULAR SCIENCE MONTHLY. assume the form of Fig. 2. The twelve films from the edges of the cube meet a square unsupported plate of film in the center. With No. 2 still on the frame, dip it again into the suds. You catch a bubble by doing this which goes at once to the center (Fig. 3), and forms such a cube as existed at the center of Fig. 1, m ! ■ > ijl'l / \, ^ \l at Fig. 1. Pig. 2. Fig. 3. only large enough to show the curvature of the films necessary to make them meet at their fixed angle. The laws of films formu- lated are as follows : 1. From each wire edge of a frame proceeds a film. Generally, if care be taken, no air will be inclosed, then every film will be in contact with the surrounding air on both its faces. 2. Only three films can meet at any liquid edge. 3. When several liquid edges terminate in one point in the interior of the system, the edges are always four in number, and the angles in- cluded between them are equal. 4. Whenever the films can fulfill these conditions, and remain plain films, they are so ; when they can not, they are curved, but so curved that their mean curvature is null — that is, if in one part of the film the law of its union re- quires an upward curvature, in some other portion there will be an equal downward curvature to compensate for it. In the films upon the cube frame, for in- stance, there is a slight curvature, just enough to enable them to meet each other on the an- gle of 120°. This is a very simple digression from the plane form, but in many other frames the divergence is very marked ; for instance, in the triangular pyramid (Fig. 4) with wires dividing each side, after a bubble has been entrapped by a second dip, the curvature is very remarkable. Plateau, the blind philosopher of Ghent, first studied this subject and formulated these laws. He began his studies with some experiments far removed from our films. In order to get some idea of the interaction of the molecular forces, he removed a mass of liquid matter he was observing, as far as he could, from the action of the physical forces. Using the well-known principle that a submerged body sinks till it has displaced its own weight of the fluid in which it is immersed, he made a mixt- Fig. 4. THE LAWS OF FILMS. 623 ure of alcohol and water of exactly the specific gravity of oil. Into the midst of this liquid he quietly introduced oil by means of a funnel. The oil lay passive between the equal downward pull of gravity and the upward lift of the alcohol and water. In this way the forces which bound the oil particles together had free play. The oil rounded itself at once into a sphere. For a time there was, of course, some chemical action between the oil sphere and the surrounding liquid ; but, in making his observations, Plateau waited till these affairs had been settled between them, and their relations became fixed. He then introduced into his oil sphere a rod, with a disk smaller in circumference than the oil sphere about it. Both of these were well oiled, and they entered the sphere without dis- turbing it. The globe of oil hung in the water, with the rod running through it in the posi- tion of the earth's axis, and the disk almost reaching to the line corresponding with our equator (Fig. 5). By means of a handle the rod was turned, at first slowly, then gradually and steadily faster. The oil sphere slipped more easi- ly around in its water socket than it would around the re- volving rod and disk, and there- fore turned upon its own axis. By varying his experiments, re- volving his rod faster or slower, Plateau made a miniature repre- sentation of a world revolving about its own axis ; he made his oil sphere throw off satellites, which revolved about the central sphere ; he also, by what he calls a trick, imitated Saturn with its attendant ring. He followed these experiments by using outlined frames of wire, such as we used for our soap films. These he adjusted around his hanging sphere of oil, and with a syringe withdrew the oil, making first a cube of oil with unsupported faces; and finally, as more and more oil was withdrawn, there resulted a system of oil films, each face of which was in contact with the water, exactly like those in Figs. 1 and 2. This was the manner in which such systems of films were first reached ; and, historically, the experiments have an interest in their relation to the subject of films as well as for the proof they offer that the material of which the films are formed has nothing to do with the forms they take on. Plateau went on from his oil Fig. 5. 624 THE POPULAR SCIENCE MONTHLY. films to those made with soap-suds and glyceric fluid. We have reversed the order in considering them, but it amounts to the same thing in the end. Plateau's researches have been carried on by Brewster and others, and the subject much enriched by later experimenters. One of the most beautiful forms has not, it is believed, been pub- lished. A sphere is outlined with three equal circles, making, when joined together at equal angles, a globe with six meridians. When this is dipped in the suds, a rather complicated figure ap- pears. It is sometimes necessary to dip this frame several times to get a perfect figure. From an axial edge of film three films start out. Just half-way between the axis and the outside curve of the sphere each of these three films meet two crescent-shaped films from two of the wire meridians, curved so that the three meet at the required angle. Sometimes when a bubble has been caught in the system, and always if a small bubble is carefully blown between two of the wires, a new figure will be formed. In an instant, as though the change were wrought by magic, the new figure flashes into existence. A long, six-sided, melon-shaped figure reaches from pole to pole inside the sphere ; from each edge of this figure, entirely unsupported as it is by the wire, a crescent-shaped film reaches to each wire meridian. The figures formed with the wire frames are usually perfectly symmetrical ; but some- times, from the peculiar form of the frame, sym- metry is not consistent with a union at the an- gle of 120°. The law in such a case is obeyed, and symmetry cast to the winds. In Fig. 6, at the first dip the figure is very unsymmetrical, though always the same. When a bubble is blown on the bottom, the figure starts out perfectly symmetrical in form. Brewster has added many experiments to those of Plateau's. The next one given is his, and a very curious one it is too. Two rectangles are made of the copper wire ; one is slipped within the other and held at right angles to it ; they are in this position dipped into the suds. The system which starts into being can be seen in Fig. 7. The central oval stands diagonally just half-way between two of the angles made by the crossed frames. Now, if the frames are gradually turned upon each other, which it is very Fig. 6. Fig. 7. THE LAWS OF FILMS. 625 easy to do, the form of the oval changes. At right angles the oval film, is four times longer than it is broad. As the angle between which the oval film stands is increased, it widens till it is nearly square. If the rectangles could be made to lie exactly one upon the other, the oval film would fill up the space. Now, when the angle of the two wire frames is made narrower instead of wider, the oval narrows till, at 45°, it is a line, and in one moment the system has changed : the oval stands between the wider angle just across its old position and at right angles to it. A still more remarkable change takes place when a bubble is blown upon the oval film, the lines being at right angles to each other. When it reaches the proper size, all the films disappear, and a hollow curvilinear cube is formed, each side curving out from the wires which define its vertical edges. At the top and bottom the wires make a cross on the film ; in each of these triangular spaces four summits appear ; colored rings form around them ; a black spot shows in the center of each summit, and the bubble bursts. If the wires are held straight up and down when the bubble bursts, the old system of films will start into being again, as if it had left its ghost behind it to recover the elements which the bubble had appropriated. Dr. Sloane, in his " Home Experiments in Science," gives some beautiful figures. A wire is bent in a spiral, with one end turned straight up through the middle like an axis. Dipped in the fluid, it gives a single spiral film curving around the central wire as a spiral staircase curves around its central pillar. He also gives some very simple and interesting experiments showing the traction of films, requiring no special apparatus or fluid, and so within the reach of every one. All the frames used in this article were made of thin copper wire bent into shape with the fingers or a pair of pliers. Of course, if the wires are soldered instead of being twisted together, and are covered with a thin film of par- affin by rubbing a so-called wax candle on them and then holding the frame above but not too near a bed of coals, the films will last longer ; but that is the only difference. The wonderful traction of films is shown by the recent experi- ments with oil upon the waves in a storm. The oil, of course, does not still the waves, but it converts the combing waves, so dangerous to navigators, into a comparatively harmless swell. It is the traction of the film which prevents the wind from drawing the water up the incline of the wave and sending it jetting up- ward to fall over in a comb. A film of oil ^-oisVo-o of an inch in thickness will hold the wave of water driving before a gale so that it can not break into spray. The closing words in Brewster's experiment on the revolving rectangles of wire bring us to another remarkable though famil- TOL. XXXVI. 40 626 THE POPULAR SCIENCE MONTHLY. iar fact in regard to films — their wonderful and changing colors, what in scientific language is called " the colors of thin plates/' because the same effect is produced in many cases where " film " is not exactly the word to use. The colors of soap-bubbles furnish one of the most triumph- ant vindications of the wave theory of light, and offer to its opposers one of the hardest possible nuts to crack. A brief expla- nation of the wave theory of light and interference, so far as it bears upon our subject, will, it is hoped, be pardoned. It is an idea so familiar to those who have studied physics, and yet so difficult of conception to those who have not, that a few words seem neces- sary in a popular exposition of the colors of films. Light is, of course, our name for the sensation, but back of the sensation there lie the physical conditions which are its cause. The theory of Newton, that light is caused by minute particles of matter shot out from the luminous body, stood the test of the simpler phenomena ; but, when it came to the explanation of soap- bubble colors, his theory, even with the marvelous ingenuity which he brought to bear upon it, broke down. If light were matter, it is impossible to see how one light can be added to another light and produce darkness, which is sometimes the case-, while, if it were motion, we can readily see how motion may be added to motion, and the result be rest. A sound can be so added to a sound as to produce silence, but the more familiar illustration is with waves of water. Two stones dropped into water will pro- duce waves, and where these meet there are points at which the water remains at its original level. This is because at these points one set of waves tends to raise the water while the other set tends to lower it, and between the two it remains where it origi- nally was. This occurs in some parts of the ocean where the tidal wave sweeps around an island and meets, one wave being half a length behind the other, in which case they simply neutralize each other. Where the crest of one wave would have been, the trough of the other would have been at the same time, and be- tween the two impulses in opposite direction at the same moment the water remains unmoved, and there are no tides. Darkness corresponds with this unmoved plane of water, and with silence in the case of sound-waves. If light were simple waves, as a result of such interference we would simply have darkness, and as a result of partial interference we would have all the gradations from darkness to light ; but a light-wave is not a simple undulation, it is made up of innumerable vibrations of various wave-lengths, each of which corresponds with a color or tone. The resultant of all these motions combined is white light. Extinguish one rate of vibration, say the smaller waves which cause the sensation of blue, and we have a wave the resultant of all that THE LAWS OF FILMS. 627 is left behind, which will be yellow. Color is a partial extinction of light — not of light as a whole, but a suppression of one of its constituents. If you take a yellow glass and allow the light to fall through it, you will find it transparent ; in the same way a blue glass is transparent ; but if these glasses are the comple- mentary blue and yellow color, and placed one on top of the other, no light comes through them. The yellow glass sifts out all the blue rays, and the blue glass sifts out all the other rays, and no light can get through. If the colors are not pure, it is usually because the yellow has some green in it, and so has the blue. Neither the yellow glass nor the blue is competent to sift out these rays, so we see green come through them both. This is the case in mixing blue and yellow in paints: the resulting green does not come from the mixture, but is the sediment — you might almost call it — left after the pure blue and pure yellow have neu- tralized each other. It is clear that, if two waves can be made to set into vibration the same medium at the same time, and from almost exactly the same center, one of them being a half-wave or several half- waves' length behind the other, we shall have, as in the case of water and sound, no movement, or darkness. If there is not exactly a half-wave's distance between them, some color-waves will neutralize each other and be extinguished, and we shall get the complementary color — the resultant of all that is left un- neutralized. This is the cause of all the flitting and changing colors in soap- bubbles, mother-of-pearl, peacocks' plumage, opals, and iridescent glass. By some means certain vibrations have been extinguished by interference, and we see the resultant of the rest. Whenever light goes from one medium into another, even when both media seem perfectly transparent, there is a partial reflection from the surface where the media meet. Hold a pin against the surface of a piece of glass (unsilvered plate glass is the best) : you will see two faint reflections of the pin, one from the front surface of the glass and one from the back, and yet the main part of the light reflected from the pin goes through, as you can easily tell by looking through the glass at the pin. So it is with a soap film : when light falls on it, most of it goes through, but there is a slight reflection from the outer surface of the thin lamina of soap-suds and another slight reflection from the back of it. The two sets of reflected waves start from points so very near each other that they both act on the medium in different directions at the same time and in the same place, and we have color. If light went forward like a regiment of soldiers in line, there might be just as much interference from the plate of glass as there is from the film of soap-suds ; but it does not — it goes out in 628 THE POPULAR SCIENCE MONTHLY. circular or, rather, spherical waves in every direction from the starting-point. It is only waves of light which are reflected back from two points very, very near each other, which produce the colors of interference. Circles which do not have the same cen- ter cut each other only at two points ; but, the nearer the two centers are, the more nearly the circumferences coincide. When the light comes back colored from a piece of mother-of-pearl, it is because the waves are reflected back from lines so close together that you can not see them, except under a very high power of the microscope, and so they interfere. Metal may be ruled with lines that give back the same sort of color, and perfect impres- sions in black sealing-wax of the colored pearl will show colors in the same way. The colors which flit over the surface of a soap-bubble each tells the story of the thickness of the film at that point. These films are exposed to the movement and drying effects of the air, and to the irregular puffs of air entering from the mouth in blowing them ; but if a film can be secured from these influences and allowed to become gradually and evenly thinner, even and regular colors appear. Blow a soap-bubble in a watch-glass filled with the soapy fluid. Let it sit in a saucer in which there is also some of the fluid, and cover with a clear glass tumbler the instant the bubble a little overhangs the watch-glass. The soapy fluid in the saucer prevents the air from getting in or out of the tumbler. Such a bubble blown from soap-suds made of distilled water and white Castile soap, which had been standing a very long while and become crystal clear, lasted for three hours and a quarter. It had no colors upon it when covered. They began to form at once : broad bands of pink and green slipped down from the apex ; then came closer and more vivid rings of color ; at last a black spot ap- peared, which grew in size. In the long-lived bubble just spoken of, the whole upper part became a metallic gray, covered with clouds of darkness and velvety black spots, the colors being crowded from the apex down to the edges. That these appear- ances are all due to interference is proved by the fact that, when the light by special means is prevented from reflection at one of the surfaces of the film, the color disappears. There is no special advantage for home experiments in having a bubble last so long. Very much the same changes occur in a bubble which lasts for half an hour as in one that lasts for three hours, only they occur more quickly. The colors of films are rarely, if ever, pure prismatic colors ; they are the resultant of certain colors left after the extinction of others. Various shades of green, from almost gold to the intensest emerald green, orange dusky with red, red magenta-colored from the admixture of blue waves, and so on, are the colors seen. THE LAWS OF FILMS. 629 Another simple and very interesting experiment is to twist a copper wire into the shape of a tennis-racket or battledore, dip it into the fluid and set it upright under the tumbler. If the saucer is partially filled with yellow beeswax, melted and allowed to harden, this can be very easily done. The colors in this case come down in bars, in the same order as they did on the bubble ; the black spot is much larger and more irregular in shape. In one instance, with a simple soap solution, this spot of intense black covered three quarters of the frame before the breaking of the film. Many films may break before one is secured which will last so as to show these effects. The cause of these regular rings and bars of color is that the film gradually thins from the top, by the slow streaming off or evaporation of the suds from the film, and for each definite thick- ness a definite color appears. The black spot which comes last of all shows that the film at that place is just one half a wave-length of light in thickness, a size entirely too small for our conception, though it can be told in numbers. The length of a wave of red light is about 3 n \ Q & of an inch, and of all the other colors smaller. The circulation and changes in the film are most curiously re- vealed by the movement of flecks of color on its surface. There are other ways of making inequalities in the film, which are revealed by the colors. A little instrument, called the phonei- FlG. 81— Phoneidoscope.

It is in all its forms a modifi- cation of, or improvement upon, this idea : an inch tube of India rubber of any length, with a funnel on one end and a mouth-piece on the other, diaphragms of thin metal or varnished cardboard being placed across the mouth of the funnel with holes of various 63o THE POPULAR SCIENCE MONTHLY. shapes cut in them to sustain the film. A very satisfactory one may be made with very little trouble and at slight cost : three feet of inch rubber tubing, a bell-glass, such as is used to shade night tapers, some pieces of cardboard or thin brass, which can be cut with the scissors, and an inch tin elbow, used in speaking-tubes and costing three cents. Fit the parts together as in Fig. 8. The diaphragms should be blackened and varnished if of cardboard ; the holes in them can be triangular, square, round, or of any geo- metrical shape. A film is drawn across the hole in the diaphragm ; it should be set upon edge till the colors are established, then it is to be laid across the mouth of the bell-glass, and into the other end of the tube notes can be sung ; but the breath must not be inhaled or exhaled carelessly, or the film will be broken. A closed mouth-piece may be made by filing off two tin toy trumpets two inches from the open end.

Fig. 9, A, B, C, D, E, F, show the forms obtained on several diaphragms with the home-made phoneidoscope described above, some with the closed mouth-piece THE LAWS OF FILMS. 631 and others by simply carefully singing into the rubber tube. The colors change constantly, and are so rich and gorgeous that they seem to have lost their transparency and to be metallic plates, ex- cept for their streaming, swirling colors. The diaphragms should, as was said before, be blackened, and the film seen projected against a black background. I simply use a piece of black mate- rial placed behind and a little below the bell-glass on which the diaphragm rests. These interference colors do not require a film of any special substance, or, indeed, of any substance at all. The air between two plates of clean, clear glass, pressed together and worked with the fingers till they are as close as possible, gives beautiful rings and fringes of color. A crack in the center of a block of clear ice, where there is not even air, but only empty space, or, rather, the ether that fills all space, gives out gorgeous colors of inter- ference. The colors of iridescent glass are due to interference. In its manufacture, by some chemical means, the surface film has been made different from the glass below, and so acts as the soap film does, and gives out its lovely tints. A drop of turpentine on the surface of water on a black tray shows fringes of color from the same cause. One of the most beautiful examples of interference color may be seen at the Metropolitan Museum of Art in New York, in the Cesnola collection of ancient glass. Originally this glass was evidently ordinary transparent glass. From some cause the sur- face has been acted upon till it lies in thin films one upon the other, sending back to the eye the most gorgeous interference colors. By the courtesy of Dr. Isaac Hall, the curator of the mu- seum, I was enabled to examine some fragments of this glass mi- croscopically. The whole surface is made up of a series of films of the most exquisite delicacy. There are tiny cavities united by a network of lines from which the decomposition has spread laterally in every direction. Flakes come off with the lightest touch, so thin that it seems impossible they should be capable of subdivision, and yet a good two-thirds glass (about one hundred diameters) shows it to be made up of a number of superposed plates. The fact that the color of this glass is due to interference is proved by putting a drop of alcohol or oil upon a flake, when the colors dis- appear or are entirely changed. As the liquid dries, the colors gradually come back. The beauty of this glass under the microscope is simply inde- scribable. Gold and silver, exquisitely wrought, and vivid with every known jewel, would be tame and colorless beside it (Fig. 10, A). The films, as they come off, are in many cases not ordi- 632 THE POPULAR SCIENCE MONTHLY. nary flat films ; the outlines are sometimes very singular, being made up of most eccentric curves in all sorts of combination. In one or two instances these scales overlapped, showing that the disintegration had taken place in a spiral direction (Fig. 10, B). This world of beauty, in both colors and form, was found within the area of one square inch or less, on a small fragment of no special brilliancy to the naked eye. Brewster describes, in the " Transactions of the Edinburgh Royal Society," some specimens A of ancient decomposed glass, but they must have been in a much earlier stage of decom- position than the Cesnola glass, judging from the figures and Jf descriptions given. He states ^ Pig. 10.— Cesnola Glass.

Here was probably the sug- gestion which has since been followed in the manufacture of our modern iridescent glass. In a piece of iridescent glass, brilliant at first, but which has been growing more brilliant for several years, I find a number of distinct centers of disintegration, show- ing the process, whether by art or by time, to be identical in kind. The question involved in the problem of air navigation is regarded by Mr. E. N. Lewis as simply one of increasing power without increasing the weight of the apparatus by which the power is applied. The supposition that the vehicle must be lighter than the air, on which experiment has mostly proceeded, is a mistaken one. " A bird can fly, not because it is comparatively light in weight (for it is not), but because it is strong." The successful air-ship will be a large structure, very light in weight compared with its strength, but many times heavier than the air it displaces, and propelled by machinery capable of developing enormous power. " The skill which has produced . . . the modern bicycle will not find the task of designing such a structure too difficult." THE PSYCHOLOGY OF PREJUDICE. 633 THE PSYCHOLOGY OF PREJUDICE. By G. T. W. PATEICK, Ph. D., PROFESSOR OF PHILOSOPHY LN THE STATE UNIVERSITY OF IOWA. THE rapidly enlarging field of modern psychology makes it possible to discuss some questions not before attempted by students of mental science. There is, however, even yet, one apparently simple problem in mental pathology which the most hardy philosopher would hardly hope to solve. This problem is to determine, by analysis of the soul, the causes, symptoms, and cure of narrow-mindedness, or mental bias. Such a research, if aught could be made of it, would be as fascinating as it would be fruitful. My present attempt is less ambitious. It is to trace out some primary laws of psychic activity in their bearing on that con- dition of mind known as prejudice. I shall not here allow myself to be entangled in a metaphysical puzzle by attempting an accu- rate definition of prejudice. To define it as deflection from truth would be to raise the ancient question, What is truth ? It will be quite sufficient for my purpose to consider prejudice as indi- vidual deviation from the normal beliefs of mankind, taking as the standard the universal, the general, or the mean. The chapter in modern psychology which furnishes the prin- ciples in quest is the chapter on apperception — really only an- other word for attention. All knowledge is the result of the union of two factors, one objective and one subjective. To know anything is to refer it to something known before. In every cognition there is a union of the group of sensations com- posing the object with a group of ideas previously acquired and now recalled. Knowledge is classification. The class is within us ; the thing to be classified is without. A piece of sugar lies before me on the table. I perceive only that it is a white object of a certain form. I apperceive, by means of the group of ideas previously associated with such white substances, that it is also sweet, hard, heavy, soluble in water — in fact, that it is sugar. The inner group of ideas varies indefinitely in complexity. Closely related ideas may be altogether wanting, as when one sees, for instance, a horse for the first time, and can only ask, What is that thing ? or, What is that animal ? One with more experience — that is, with more related ideas — apperceives that it is a horse. A jockey, however, apperceives all his " points " ; a zoologist still more. We say that the jockey or zoologist really sees more in the horse than the ignorant man, yet the image made upon the retina of the eye is the same in each observer. Similarly, in 634 THE POPULAR SCIENCE MONTHLY. reading, we cast the eye rapidly down the page and, although we do not see one half the words, or a fraction of the letters, yet we catch the sense. If it happens to be a letter from a well-known friend, we read also, as we say, between the lines. Really we read out of our own heads. The subjective or a priori factor is simplest, therefore, when, as in the cases given, it is merely the class notion, horse or sugar ; it is most complex when it represents, for instance, a whole system of astronomy, as when, in a falling body, there is apperceived a law of gravitation. But, simple or complex, it follows, first, that unless there be an inner group of ideas to which the object may in some way be referred, knowledge of it is impossible ; and, secondly, that the character of the resulting knowledge depends upon the character of the inner group of ideas. You and I, therefore, see everything to some extent differently. You see things from the standpoint of your previously acquired groups of ideas ; I from mine. Strictly, no two persons can see the same thing in the same way, for it can never happen that two persons have precisely the same groups of ideas relating to any subject. These depend on our past experience, on our education, on the beliefs of our times, on our various sects or parties, on our pet theories, our interests, and our desires. Here is a simple illustration. Suppose an artist and an engineer, stand- ing side by side overlooking a tract of country. What they per- ceive is the same ; what they apperceive is wholly different. To the engineer the country presents itself as a possible line for a railroad, with here advantageous grades and there economic bridges. Before the artist is spread out a landscape, with light and shade and harmony of colors. Suppose, again, a plot of level ground in the suburbs of a city. A college student riding by apperceives it as a possible ball-ground ; a young girl, as a tennis-court ; a speculator, as an addition for town lots ; an under- taker, perhaps, as a possible site for a cemetery. In the primary laws of knowing, above stated, we discover the ground principles of the psychology of prejudice. The re- sults may be summed up in the form of two laws : 1. We see only so much of the world as we have apperceptive organs for seeing. 2. We see things not as they are but as we are— that is, we see the world not as it is, but as molded by the individual peculiari- ties of our minds. Applications of the first law I shall state briefly ; of the second, more in detail. The eye is limited by its structure to the recep- tion of ethereal vibrations between the colors red and violet. The ear converts into sound only air-vibrations of a limited rapidity. Just so the mind, in its reception of knowledge, is THE PSYCHOLOGY OF PREJUDICE. 635 limited by the quality and amount of its previous acquisitions. '" No man/' Emerson tells us, " can learn what he has not prepara- tion for learning, however near to his eyes is the object. A chem- ist may tell his most precious secrets to a carpenter, and he shall be never the wiser — the secrets he would not utter to a chemist for an estate. God screens us evermore from premature ideas. Our eyes are holden that we can not see things that stare us in the face, until the hour arrives when the mind is ripened ; then we behold them, and the time when we saw them not is like a dream." Instinctively, therefore, we seek the mental food that our minds are prepared to digest — that, namely, which is most clearly related to what we know already. In conversation, notice how people brighten up when you tell them something that they know already, especially if it is something they have long be- lieved or themselves discovered. In society we know how to make ourselves agreeable by speaking to each person on the subject of his peculiar interests. If we are wise, we shall engage each person in subjects of conversation about which he is best informed. By so doing we can not only make ourselves agreeable, but lay by a stock of useful information at the same time. Such a course is by no means easy. We fall naturally into the vice of parading our bwn knowledge, and we like to hear others talk, not of their interests, but of ours. Sometimes persons in conversation act simply as foils each for the other. I listen to your stories only that you in turn may listen to mine ; and in the next company I tell not the ones I heard, but the ones I told before. Thackeray, in " Henry Esmond," hits upon this human weakness. " They emptied scores of bottles at the ' King's Arms,' each prating of his love, and allowing the others to talk on condition that he might have his own turn as a listener." We like also to read that which favors our side of a question. The Republican subscribes for a Republican newspaper, and the Democrat reads the organ of his party. In the last political cam- paign it was no doubt true that advocates of free trade or of tariff reform, and advocates of protection, read for the most part liter- ature favorable to their respective views. The churches plead for greater consensus of opinion, yet the Methodist subscribes for a Methodist paper, the Baptist for a Baptist paper, the Roman Catholic for a Catholic paper. In general we read the organ of our own sect or party. There are, of course, some valid economic reasons for so doing. I shall speak of these reasons below. But, if truth alone were sought, the plan we pursue would be the worst plan possible. Sometimes even we indignantly refuse mental food that might serve as a corrective of our possible one-sidedness, in- stinctively avoiding that which we feel can not be assimilated without a dangerous readjustment of our mental possessions. 636 THE POPULAR SCIENCE MONTHLY. The skeptic in religion opens a book on Christian evidences, only to close it in haste when he perceives its trend ; while the pious believer, who picks up the work of Strauss or Renan, drops it like a burning coal. We avoid books, men, sermons, society, that are not, as we say, congenial. Hence the trouble we have in getting our books read by the very people for whom they were written, or in getting our articles printed in the journals that circulate among the readers we desire to reach. The preacher prepares a vigorous sermon for " sinners," but he preaches it to his own devout peo- ple ; the " sinners " are not there. Our psychological law of prejudice thus developed teaches us that, since we seek not for what may correct our possible errors,, but for what will confirm our already acquired opinions, our men- tal life always tends toward intensification or involution. Evi- dently this tendency of the mind toward involution will grow with age, and our every-day experience confirms this deduction. Teaching new tricks to old dogs is easier than giving us new ap- perceptive organs when middle life is past. The old man changes his politics rarely, his religion never. He lives from within. The mind becomes more and more a microcosm. The cerebral tracts show well-beaten paths of association. The brain becomes hard- ened and fixed. "An old man/" says Dr. Holmes, "who shrinks into himself, falls into ways which become as positive and as much beyond the reach of outside influences as if they were governed by clock-work." The brain, he continues, has its " systole and dias- tole as regular as that of the heart itself." " Minds roll in paths like planets : they revolve This in a larger, tbat a narrower ring, But round they come at last to that same phase, That self-same light and shade they showed before. I learned his annual and his monthly tale, His weekly axiom and his daily phrase. I felt them coming in the laden air, And watched them laboring up to vocal breath, Even as the first-born at his father's board Knows ere he speaks the too familiar jest Is on its way. by some mysterious sign Forewarned, the click before the striking bell." The older we get, the larger becomes the subjective factor of knowledge and the smaller the objective. We are, as said the obscure sage of Ephesus, like those asleep, withdrawn each into a private world of his own. We can now understand that state of mind described by the word "confirmed." We hear of a con- firmed pessimist, a confirmed protectionist or free-trader. Some- times we apply the word without shame to ourselves, saying that experience has confirmed us in this or that opinion, not know- THE PSYCHOLOGY OF PREJUDICE. 637 ing that to a considerable extent we have selected our own ex- perience. Our second law affirms that we see the world not as it is but as modified by the individual peculiarities of our minds. The illusions that result are Bacon's well-known " idols of the den," doubtless the most fruitful of the four sources of error pointed out by that clear-headed philosopher. For our starting-point we may turn again to physics and physiology. Vibrations of the luminiferous ether of varying rapidity are perceived by the eye as a harmony of colors. Vibrations of the air of varying rapidity are perceived by the ear as a harmony of tones. Unless, now, we are prepared to say that the colors red or green, or that the tones a or a', are like or in any way similar to the motion of the ether or air ; unless, further, we are prepared to say that, corre- sponding to the subjective harmony of colors and tones which we feel, there is an objective harmony of motions in the ponderable stuff, then we must admit that we have here cases of the great primary illusion of a phenomenal world of ideas like a noumenal world of things-in-themselves. With this ancient problem of per- ception we are not now concerned, but it serves as an illustration of our mental law of apperception. As the eye and the ear, each according to its structure, make over the manifold motions of the external world into sensations of light and sound, so the mind makes over the materials of knowledge into this or that product according to its peculiar constitution. Observe, however, this difference between the two cases. While the eye and the ear vary little in structure in different individuals, the variations in mental structure are endless, being determined by our environment, edu- cation, and inherited peculiarities. Color-blindness is compara- tively rare and limited to a few colors ; psychical blindness, in a greater or less degree, is a defect no man is free from. The simpler illustrations of this law need not detain us. We put any new phenomenon into that class of our previous notions which it most closely resembles. A child who sees a cow for the first time calls it a horse, if familiar with horses. The same plant may be apperceived by a girl as a flower, by a farmer as a weed, by an old woman as an herb. The story of the precocious boy is in point. He sat under a tree as three strangers passed by. The first said, " What a fine stick of timber ! " " Good-morning, car- penter," said the boy. The second, " What excellent bark ! " "Good-morning, tanner." The third, "What a beautiful tree- top ! " " Good-morning, artist." He had correctly interpreted their vocations from their manner of apperceiving the tree. Our habits of thought, once started, grow on any food. We go by chance to hear a lecturer of an opposite party or sect, and come away confirmed in our own views. This law of mental inertia 638 THE POPULAR SCIENCE MONTHLY. tends constantly to produce one-sidedness. Nature strives ever to rectify this tendency by presenting to us an unsorted variety of details, and succeeds in keeping most of us within the bounds of sanity, though not of perfect balance. " The complexity of our environment," says Kibot, " is our safeguard against automatism." But our ideas are ingrowing, and need to be constantly watched and corrected. Insanity is a matter of degree. When the " fixed ideas " which few of us are without pass a certain point and get too obtrusive, we become monomaniacs. Men of one idea, men of mental bias, narrow-minded men, present milder cases of the same disease. Fruitful illustrations of this law may be seen in the systems of thought that have prevailed since the days of Pythagoras. Systems of words would be a better name for many of them. As in our seeing, so in our thinking, we are limited by the ap- paratus that happens to be at our command. For most of us,, at least, the available apparatus for constructing a philosophi- cal system is a philosophical vocabulary. From this fact and the further one that these vocabularies are largely inherited from the schools, it results that the apperceptive organs of meta- physicians are wofully inadequate to the task they undertake, namely, the cognition of ultimate realities. It is no wonder, therefore, that these realities have been persistently apperceived under so many different forms in the various metaphysical sys- tems, supported by so many "hide-bound adult philosophers."' Many a well-meaning philosopher has got caught in the swing of a certain terminology, till his thoughts have become slaves to the movements of his tongue. We are reminded of Aristotle's, categories, Kant's map of the mind, Comte's three stages, Hegel's thesis, antithesis, and synthesis, the absolute and the finite, sub- ject and object, mind and matter, body and spirit, noumenon and phenomenon, real and ideal, rational and empirical. This is the " tyranny of formulas " from whose iron rule science is now escap- ing, but which is still the terror of philosophy and religion. The danger of words and formulas may be well illustrated further by the mischief made in philosophy by the presence of negative terms. These are the words which in the finished systems of the philosophers mark, we may say, the absence of thought. We recall the "Infinite " of Zeno and Kant, the "Ab- solute " of Fichte and Hegel, the " Supra-essential " of Pseudo-Dio- nysius, the " Unconditioned" of Hamilton, the " Unknowable " of Spencer, the " iVctf-ourselves " of Matthew Arnold, the " Uncon- scious " of von Hartmann, the "Immortality " of Christian believ- ers, the m ov of the Greeks, and the " iVon-being " of the Hege- lians. These represent the unfathomable places in thought, which we bridge with a negative term and pass on blithely as before, but THE PSYCHOLOGY OF PREJUDICE. 639 presently find ourselves using them as conceptions regularly- formed. In Goethe's well-turned phrase : " Denn eben wo Begriffe fehlen, Da stellt ein "Wort zur rechten Zeit sich ein." But if prejudice prevails in philosophy, what shall we say of religion ? The race as a whole is divided into a large number of religious systems, and each system into sects. Every individual apperceives the " eternal truths " from the standpoint of the sect in which he was educated. Rarely does he change from one faith to another, and when he does so it is not often for his peace of mind. Such an " Exodus from Houndsditch," in Carlyle's homely phrase, is accomplished only " in a state of brutal nakedness, scan- dalous mutilation." Why ? Because religious ideas are deep-seated and fundamental. To receive into the mind a group of new and foreign notions of such a kind requires a breaking up and read- justing of the old order such as few can undertake with safety. The very psychological laws that we are studying, however, may teach us that these world-wide differences in opinions are not destructive of the eternal verities of religion, but only that these verities are distorted when narrowed down to fit our par- ticular systems and our individual capacities. There is a curious science called the science of interpretation, whose business it is to translate the facts and thoughts of the world into phrases comprehensible to a mind limited to a certain system of ideas. Have we ever stopped to think what a confession of shame such a science carries on its face ? To interpret is, in some sense, to change, to distort. An instructive illustration of this branch of learning may be seen in hermeneutics, or the sci- ence of the interpretation of the Scriptures. Never in any litera- ture were thoughts expressed in so simple, straightforward, and honest language as in the books of the Bible, or in language less in need of interpretation. What this science really has in hand is the pitiful task of fitting a vast variety of thoughts into the limited number of forms of some system of theology. So, every- where, it is a mistake to interpret things. It is better to let Na- ture carry on her work of rectification, by allowing the bare facts of the world to project themselves freely against our minds and be perceived as they are, or make for themselves apperceptive organs. Interpretation leads to over-interpretation. This evil becomes prominent in connection with those studies which are not yet exact sciences, such as sociology, ethics, metaphysics, and the- ology. Here, as we know, we very often have to make an allow- ance for the " personal equation " of the author — unless, unfortu- nately, belonging to the same party, sect, or school, we have 640 THE POPULAR SCIENCE MONTHLY. blindly accepted him as a guide. We understand that he writes from a certain standpoint, and that unconsciously and inevitably he will see things, not just as they are, but as tinged by his own subjective light. Where, for instance, shall we find a perfectly just history of philosophy ? Not in Schwegler, who glances over the past through a pair of thick Hegelian spectacles ; nor in Lewes, who apperceives the opinions of thinkers with a positiv- istic bias. Theology is quite a different science as presented by a St. Augustine and a Pelagius, by a Protestant and a Romanist. The Socrates of Grote is not the same man as the Socrates of Cousin. Jesus, even, is seen in an entirely different light by Fleet- wood and by Renan. The Greek thinkers, especially Aristotle and Plato, have suffered much at the hands of modern writers, being used as props to bolster up every man's system of science or philosophy. Over - interpretation is really only the logical outcome of another wide-spread evil, that of over-systemization. This is a prevalent modern vice. It is the abuse of classification, or the scientific method. It is the tendency to group under any outlined system or theory more facts than properly belong to it. We fall in love with our favorite theory, and it seems to us to possess exaggerated virtues, and to be able to explain all phenomena. Darwinism in biological science, utilitarianism in ethics, and He- gelianism in philosophy, are examples. The latter is a very beau- tiful illustration of over-systemization. Hegel, with his thesis, antithesis, and synthesis, fondly thought he had spread a net that should capture the universe. But the strain appears to have been too great, and already we see the ruins of a great collapsed phi- losophy. Over-systemization is apparent also in the present rage for publication, especially in Germany. Every university man must publish a book, and every book must present either some theory or the results of some original research. Under these cir- cumstances, it is not surprising that the demand for new material exceeds the supply. The result is, that the author falls back upon his own mental resources. He makes a new and original hypoth- esis and apperceives his facts to fit his theory. Adopting, as it would seem, the maxim that it is better to be original than reasonable, it is considered no disadvantage if the new hypothesis is somewhat fanciful and startling, as for instance that Schiller, not Goethe, was the author of " Faust," or that Shakespeare's plays were written by Bacon. I have explained the narrowing effect of " schools " and sys- tems, and the mental bias which results from over-systemization ; but the use as well as the abuse of systems must not pass un- noticed. There is good in them as well as evil. Trendelenburg says that a system is as necessary for a thinker as a house. We THE PSYCHOLOGY OF PREJUDICE. 641 must get our knowledge into some sort of unity, otherwise it can neither be retained nor used. The Ptolemaic system of astronomy was far better than none ; it served as a framework for a great body of facts, distorted though they were by the false theory. We are lovers of systems. Most of us prefer unity to verity. We want order and discipline among our ideas. Of absolute truth we can not speak ; of order and consistency we may. Any new system may find numerous adherents, if only it be presented in the threefold form of unity, consistency, and repetition. It is easy to understand this love of systems. They save us from the inevitable mental bankruptcy which would result from the influx of a mass of uncoordinated impressions. Grant us a system, all complete in its several compartments, where we can pigeon-hole each newly acquired fact, and peace and harmony reign within. No matter if the system be so narrow that we can dispose therein only a limited number of impressions ; if only we have confidence in it, all heterogeneous elements we may cast out as " error." We love harmony and hate antagonisms. It is mental economy, therefore, for us to read the organs of our sects and parties, to converse with those with whom we sympathize, to listen to that which we believe already. Great historical disturbances bring out systems. It is in this way that we get ourselves ready for troublous times. A system is a kind of mental fortress, a vantage- ground from which to scrutinize each new idea, and apperceive it as a friend to be received or an enemy to be, on a priori grounds, repelled. System-forming is thus the process of mental involu- tion, which is the law of individual minds, as evolution is of the mind of the race. Mental involution shows another phase in habit. Habits are well-knit associations. They make us machines, committed forever to a determined manner of acting and thinking. A habit is itself a mental bias. Stereotyped and inherited, it becomes instinct, where we see the full fruition of the involution movement and the dead level of automatism. From this point of view, instinct has been well called " lapsed intelligence," if by intelligence we mean power to adapt ourselves to new surroundings and to avail ourselves of new impressions. Habit is opposed to progress. In history, our reformers — Jesus, Savonarola, Luther — have been habit-breakers. Genius, too, is only the name of that disposition which rebels against the law of mental involution, breaks away from systems, and goes out in search of the objective truths of nature. Thus, side by side with the involution movement, we find the evolution movement. In the animal kingdom, it is rep- resented by the persistent but mysterious tendency toward vari- ation ; in human history, by the comet-like appearance of the reformer ; in art, by the lawless product of genius. All these are VOL. XXXVI. 41 642 THE POPULAR SCIENCE MONTHLY. factors in the upward world-movement which saves us from the stagnation of the relentless law of habit. But habits, like systems, have their good side. They enable us to do a vast number of actions with the minimum of attention and the least expenditure of nervous energy. Education consists largely, as has been said, in making habitual as many good ac- tions as possible. The training of domestic animals is purely the formation of good habits ; the training of children is largely so. Every time we form a good association and send it down into the region of the unconscious, we practice mental economy. Habits, therefore, are at the same time our salvation and our damnation. This is the great dilemma in education. Extremists like Rous- seau, impressed with the danger of habits, condemned them all outright. Perhaps we may say that it is the abuse of habits, the falling into fatal ruts, that constitutes our prevailing sin. The laws of prejudice that we have examined naturally sug- gest one or two questions. Is there any escape from this narrow- ing of mind that accompanies the hardening of the brain ? If not, are there any pedagogical principles the application of which in educational systems may retard the involution and hasten the evolution movement ? It is not my purpose to attempt to answer these questions here ; but, if the first one must be answered in the negative, the latter may certainly be answered in the affirmative. Our psychological principles have already shown us the direction in which the solution of this problem must be sought. There must be persistent emphasis of the objective factor of knowledge. The senses, the primal source of all our. knowledge, must be kept open and alert. This is vastly more difficult than at first appears. The man prejudiced by his interests has his eyes and ears open, and yet, being open, they are shut. More than twenty centuries ago an old Greek philosopher said, " Eyes and ears are bad wit- nesses to men having rude souls." To escape mental bias, we must not only have our senses open to the outer world, but we must apperceive this world as it is, not as warped by our receptive faculties. But, however excellent this advice, it is as impossible for us with minds already formed to follow it as to see the ultra red or violet colors with our eyes constituted as they are. The remedy is to be found in education, especially of the young. For- tunately, we live in an epoch of objective education. The training of the senses, thanks to the labors of Rousseau, Pestalozzi, Froebel, and their disciples, and thanks to the retroactive influence of the physical sciences, is now the great central thought in peda- gogical systems. Unfortunately, it is still too largely theory and too little practice. In our primary as well as in our secondary schools we slip back too easily into the lazy scholastic, deductive methods. The tendency, however, is the other way. THE PSYCHOLOGY OF PREJUDICE. 643 Our free press, also, and our free speech are great educators. In these days we are compelled to see and hear and think. The narrow-minded man is unhappy and distracted. He is no longer protected in his little system by college or cloister walls. A myriad unwelcome facts peer in at him from every side — from the circulating library, from the interesting novel, from the omni- present and iconoclastic newspaper. The man of mental bias is veritably a victim of persecution. Optimists tell us that the world is growing honest. I am optimist enough to believe that it is growing broad-minded. Perforce it must. The air is full of everybody's ideas. They circulate everywhere and act as a series of incessant shocks wherever they find a mind too narrowly planned to admit them. Hence men are beginning to avoid sys- tems as the cause of more friction than they save. They are willing to sacrifice a narrow love of unity and consistency for a broader harmony with the spirit of the age. What is likely to be the result of this general breaking up of old unities, systems, habits ? An increase of insanity ? By no means. Insanity proceeds from the opposite movement, from the involution of the mind upon itself, till fixed ideas can no longer be rectified by objective facts. The results will be good and bad : good, in encouraging inquiry and in substituting the love of truth for the love of consistency ; bad, in discouraging a certain moral earnestness and enthusiasm which are the outgrowth of strong conviction, for the narrower is one's system of thought, the stronger often are one's convictions of its truth and importance. The extreme form of this union of prejudice and intensity we call fanaticism. If not in fanaticism, at least in enthusiasm, there is an element of good which we must not overlook. Men possessed with one idea are men of action. Enthusiasts carry for- ward great movements. The development of the intellect is the weakening of the will. Children and animals act out every thought. Education is a training in the inhibition of movements by the higher intellectual processes. The man of many-sided mind finds every volition " checked " by some antagonistic idea. The correction of mental bias, therefore, will result in a certain loss of spontaneity. But progress will not suffer. If we move more slowly, it will be more surely. "What we lack in enthusiasm we shall make up in balance. " The great fault of non-manual training schools," says Prof. C. M. Woodward, " is their haziness. The pupils look at multitudes of things but do not perceive them. Having eyes, they see not ; and having ears, they hear not. There is too much that is dim and muddy and feeble. Substances elude the grasp ; shadows, uncertain and fleeting, are too often the only results. The method which reason and experience both approve is reversed, and pupils are put to committing to memory matters which they are not prepared to understand." 644 THE POPULAR SCIENCE MONTHLY. ORIGIN OF LAND-OWNERSHIP. Br DANIEL E. WING. IT has been asserted that nothing is so devoid of natural justice and moral right as private ownership in land — the sole domin- ion over a portion of the earth's surface which one man claims and exercises to the exclusion of the dominion of every other man therein. The proposition would be true, and private ownership . in land would work the greatest injustice that the mind can con- ceive— human slavery absolute — if it were possible that one man or a set of men with one common motive could appropriate all land. But such a thing is absurd. And it is denied that private ownership in land as now constituted is unjust, or detrimental to the best interests of mankind associated in the social organization of the world. Let us assume that primarily land was held in common, or a yet stronger proposition, that it is a law of nature that all land shall be so owned and enjoyed. By the same law of nature, and by reason, he who first began to use a particular spot or field ac- quired therein a kind of transient property that lasted so long as he was using it. The right to use it lasted so long as possession continued, and with death or removal, possession ceasing, the per- sonal right of usage ceased also, and the land was open to the next occupant. That is, whoever was in occupation acquired for the time being a sort of ownership, a gwasi-ownership for the purpose of subsistence, or rest if you please, and to drive him therefrom by force would be a violation of the same law of nature. But once he quitted it, another, having the same right of use and an equal claim to occupancy, might seize it without injustice. Applying this system to an imaginary or ideal state, to men hav- ing a common interest and few wants, and those supplied from nature by the simpler forms of industry, the result is a picture of comfort and competence for every one of the community ; in fact, an extensive household, with its respected father or chief, around whom cluster the helpless and inexperienced. But will any one say that no more stable way of holding land than this is required in a society teeming with population, where each man eager for gain is pressing, pushing, and jostling his neighbor — where the industry of one man may have added to the fertility and usefulness of his land what neglect and sloth have denied to that of another ? Every man's hand would be raised against his neighbor, and there would be no domestic quietude or personal security ; and, consequently, no social bond, civil govern- ment, or commercial life. This insecurity I apprehend to be the prime cause of establishing a more permanent property in land. ORIGIN OF LAND-OWNERSHIP. 645 Necessity gave to the occupant more than a mere transient in- terest. Necessity gave a species of 'property in the soil, and, in order to insure that property, recourse was had to social organiza- tion, to laws, and punishments for violation of laws. Now, when man enters into civil society and partakes of its benefits, he must surrender some of his absolute personal rights, or exchange them, as it were, for such relative rights as are inci- dent to men as factors of society. This is no loss or hardship, for he gains by exchange that security of person and property which it is the object of civil government to insure ; whereas, in the nat- ural state, every other man being possessed of the same absolute rights of person and property, there would be no security either of person or property. The rights, then, belonging to a man in civil society, which we will call his civil rights, are the absolute right belonging to him by nature, so far restrained by civil law as is necessary and expedient for the general advantage of the community. It being evidently natural that man should acquire a right of property in the soil, the next inquiry is, how property became actually vested. As occupancy gave the right to temporary use, so occupancy also gave the original right of property in the thing used. The same law of nature would suggest that the first occu- pant who had by his industry and thrift added to the utility of the soil — in fact, developed by labor the only value therein — should become the owner. The product of a man's labor, the work of his hands, is his. "Whatever he removes out of the condition that nature has left it in, he has mixed his labor with and joined to it something that is his own, and thereby acquires a property in the thing itself. Necessity, arising from insecurity of person and property, being assigned as the first and primary reason for pri- vate ownership in land, the right of a man to the product of his labor may be cited as a secondary reason. Although by theory of civil law as well as by usage, ripening into universal sanction, the ownership of land is deemed to be in private individuals, can it be said, after all, honestly and ration- ally, that the individual has an ownership of the soil as absolute as in the case of personal property ? His interest is rather pos- sessory for the time being, the manner of his enjoyment usufruct- uary : he can not move the land or carry it with him from place to place ; he can not change the nature of it ; he can merely draw from its substance for the time being, to the exclusion of all others from such use. In such exclusive use he is as much supported and upheld by natural justice and moral right as in the case of personal property. His labor and capital have improved it, beau- tified it, rendered it more productive, and enhanced its utility ; and, so far as value is concerned, it will be argued hereafter that 646 THE POPULAR SCIENCE MONTHLY. land has no value except as labor lias made one for it. So I sug- gest the possessory and usufructuary interest of the individual in land is not the absolute ownership and proprietorship of the soil. Let us see if anything more than occupation, by successive individuals, is contemplated by social law, or by statute law in England or America. In England the proprietary ownership of all land is by common law in the people as represented by the king, the trustee under the social system of all their common in- terests, rights, and properties. In the United States it is vested directly in the people. By the Constitution and statute of New York State, "the people of the State in their right of sovereignty are deemed to possess the original and ultimate property in and to all lands within the jurisdiction of the State." This I understand to signify precisely what the common law of England and the universal law of nature are : namely, that all property in land was originally vested in the people in common ; and if there ever hap- pens a time when no person is in occupation of any portion there- of, the tenancy in common of the whole community immediately goes on again just the same as when, after the first occupant or squatter had relinquished his temporary occupancy, the whole community was again in possession, every man having the right to occupy it, but all in common. So I assert that private owner- ship, so called, is not a proprietary quality. It extends to and includes only the use ; the absolute ownership of all land being, in fact, in the community composed of all individuals. Suppose that every new-born offspring of that community by virtue of natural right becomes a tenant in common with all indi- viduals then existing, should he share in the possessory right or use of a particular piece of land already in occupation of an indi- vidual ? By being debarred from such possession, it may be that he is deprived of a natural right, but he becomes a member of the society into which he is born, governed by its laws for the time being, surrendering some portion of his natural and absolute rights for the protection guaranteed by the existing social laws, and participates in all the advantages now existing as well as in the advancement and social improvement of all previous time. Is he, then, defrauded ? The possession of land remains in the occupant by right and justice till such time as he does some act indicating his intention to abandon it, whereupon it becomes common property, and liable to be again appropriated by the next comer. Sale and delivery of possession to a purchaser are forms for the convenience of social government, and instituted with a view, I apprehend, of preserving the quiet and security of social order. By means thereof the present occupant indicates his intention to abandon the land appropriated. The deed of conveyance is an evidence of ORIGIN OF LAND-OWNERSHIP. 647 that intention ; and the purchaser, being the first acquainted with such intention, steps in and seizes the vacant possession. Thus the act of abandonment gives the new taker a right against the first, acting by what is known in law as an estoppel, and posses- sion or occupancy is by natural law good against all the world besides. The most effectual way of abandonment is by death of the occupant, when both the possession and intention of keeping possession ceasing, the right of occupancy by natural law also ceases, and the land is open to the next taker. The custom, which has ripened into statute law, that the next of blood take on decease of the occupant, has its foundation in natural law instead of mere civil right. A man's children, those of his blood, his nearest relatives, are usually about him on his death-bed, and are presum- ably the first witnesses of his decease. They become, therefore, presumably and by natural law, the next occupants, until in pro- cess of time this frequent usage ripened into social law. I have gone to this length in discussing the origin of so-called private property in land to ascertain on what support of natural justice and moral right it rests. This consideration is the foun- dation upon which stands the whole superstructure of proposed single taxation ; for, " if private property in land be just, then is the remedy proposed a false one." If the individual has no such property, or the tenure by which he holds occupancy is supported by natural law, and his use of the land is consistent with natural justice, even though it works a wrong to another, the fault is not due to " maladministration of social laws," in this particular at least. Investigation leads me to assert that the occupant of to-day holds by a tenure as much supported by natural justice and moral right as did the first taker ; and more so, because he has, by ex- change of his capital, the product of his labor, purchased the improvements added by every occupant preceding him. Land has no absolute value. In a natural state and unoccu- pied by man it produces no wealth. It is only as capital and labor are applied to it that it becomes a factor in wealth, and hence acquires a commercial value. I agree to the proposition that what a man makes or produces is his own to enjoy, to use, to exchange, or to give ; that no one else can rightfully claim it, and his exclusive right to it involves no wrong to any one else. So, if by his labor and capital man in occupation of land removes it from the state in which Nature has left it, improves it, renders it more productive, or if he acquires by exchange the improvements already made therein by another, he has joined to it something that is his own, and has created a value in it that did not exist before. Admitting the proposition that government, representing in the social state the common rights of the community, may 648 THE POPULAR SCIENCE MONTHLY. interfere and take the land occupied by such, individual, as the whole community acting in common as owners might have ejected the first taker, yet on the principle of natural justice and moral right it can do so only upon reimbursing the occupant for all improvements to the land — that is, for all the product of labor expended upon it, including that which he has become possessed of by purchase. Since all the value in land is due to the employ- ment of capital and labor, such reimbursement should equal the present commercial value of the land to the occupant (owner). Upon this naturally just and moral principle rests the constitu- tional restriction to eminent domain, that private property shall not be taken for public use without just compensation. Nor can I see that, because land occupied by an individual may have a value beyond the value of the labor expended upon it, by reason of its proximity to other lands upon which greater wealth has been expended by other individuals, the injustice of depriva- tion is lessened. The same rule of reasoning applies to this un- earned increment as applies to the actual labor value of the land. The present owner has acquired it by the exchange of his capital, which was the product of his labor elsewhere, and it is really as much a value made in the land by the expenditure of capital and labor as that represented by the actual labor of the first occupant. If so, it is included in the present commercial value of the land. And why should land alone be deprived of this unearned in- crement ? Other possessions receive a borrowed value from ex- traneous circumstances, such as the occurrence of war, change of fashion, etc., and no one suggests that it is not a true value to which the property or commodity is entitled. To recapitulate : By natural law land is owned by all men in common. The first taker or occupant might rightfully appropriate so much to his exclusive use as a proper use thereof permitted. His possession, to the exclusion of every one else, might con- tinue so long as he used the land, or while he was using it. Upon possession ceasing, his right to use it ceased, and the land was again held in common, subject to be again appropriated for use. Insecurity in the use, since the occupant's labor added to the soil what before it was devoid of — a commercial value — necessi- tated a more substantial tenure, a sort of property in the soil which is called private ownership. To secure this to individuals, social governments and social laws sprang into being. These latter, either by common usage long established and acquiesced in, or by express provision, not only recognize but assert the law of nature in respect to property in land. THE GROSS AND NET GAIN OF RISING WAGES. 649 Sale of land in occupation of an individual is an act indicating his intention to abandon it, a grant or conveyance being the means established by social law to signify this intention. The purchaser, being the first acquainted with such purpose, seizes the vacant land and is the next taker by natural law. The consideration paid represents the capital and labor expended in the land by all occupants, and the justice of such payment is sustained by every principle of natural law and moral right, since the capital and labor so expended represent all the com- mercial value that the land possesses. And, finally, to deprive the individual of his occupancy and possession, although it be to reinstate the owners in common, can only be in natural justice and moral right upon payment of the value of the capital and labor represented in the land, which is the whole commercial value of the land. It follows, then, that the demands of natural justice and moral right would be ignored if all taxes were put upon land, because one form only of labor and capital would be thus compelled to bear the whole burden of taxation. ♦»» THE GROSS AND NET GAIN OF RISING WAGES. By ROBERT GIFFEN. IN the discussions to which former papers of mine on working- class progress have given rise, there are some criticisms which have interested me very much. They are made by members of the working class themselves, who are slow enough to admit the average increase of their money earnings in the last fifty years which the figures demonstrate. But, admitting some increase of money, they go on to say, and admitting, too, the low prices, the improvement after all is not without drawbacks, or, as I have suggested in the above title, it is mainly in the gross. There are drawbacks which take away much of the apparent advantage. A general statement like this, apart from particular allegations to support it, could not but excite my attention, although I have avoided hitherto any discussion of it. It is a good rule to do one thing at a time. An improvement of money earnings and no increase of prices appeared to be two points worth establishing, whatever the drawbacks of a less apparent kind, and which the working classes could themselves best appreciate, might be. But while avoiding the discussion hitherto, I have been none the less observant, for the simple reason that each class knows its own grievances as no others can, and that such complaints, though easy enough to prove unfounded, are apt to cover facts which 650 THE POPULAR SCIENCE MONTHLY. will reward investigation — which will throw light, when properly understood, not only on the particular problems in hand, but on larger problems. I propose in the present paper to communicate some reflections which I have made. The alleged drawbacks, when considered, do, in fact, suggest for consideration questions of a weighty nature, which go to the root of ideas of progress, and affect the most general views of the prospects of modern civili- zation. The alleged drawbacks of which I speak are mainly the follow- ing : First, it is said, workingmen in many cases have more to pay for rent than they would have to pay when earning less money under different conditions, or they have to pay railway or 'bus fares or similar charges for conveyance to and from their work, which are in the nature of an increase of rent. Conse- quently, although the money wage is more, the workman is not so much better off than he was, because a large part of that money wage has to be paid as a fine, practically, to enable the workingman to be in a position to earn it. In other words, the gross sum is more, but the net sum is not so much more. It is easy to perceive, also, that this principle may have a much wider application than may at first be surmised. The case usually thought of is that of rent, or an equivalent fine on a workman, which he pays in order to be in a certain place where the money wage can be earned. Suppose the climate in which he has to live in order to earn a larger money wage than he can get elsewhere is so exhausting as to compel a larger consumption of food in order that the money may be earned ? The question of gross and net is thus of a wide-sweeping kind. Next, it is maintained that along with a great increase in pro- duction, which has undoubtedly taken place, there has come an increase in the severity of the labor, and that the workman's remuneration has not risen in proportion. It seems to be sug- gested at times that the increase in the labor is itself an evil, even if it were proportionately remunerated, but the complaint rather is that the severer toil is not adequately compensated ; the workman has a severer call made on his energies, and he is not so much better off. To be able to earn more money, it is sometimes urged, he must, in fact, spend more money on food and other things than he formerly did. Here, again, is a question of gross and net, and it will be observed how the last complaint raises in a different form the question already suggested under the first head by a consideration of the effects of climate. A distinction is made between the gross earning and the net surplus, the difference being something which the workingman has to pay as a fine to enable him to earn the net sum which he wishes to spend. Last of all, it is maintained that on all sides the scale of living THE GROSS AND NET GAIN OF RISING WAGES. 651 has become more expensive. The workingman has to get more food, clothing, and shelter for his family than he would formerly have had to get ; more is expected of him ; and he has to pay for such things as the education of his children to a much greater extent than he would formerly have had to pay. In this way the strain upon the workingman has increased. As I understand the complaint, he is no more a free man than before. His energies are mortgaged in advance, and he has all the old difficulty to keep his footing in the world. Now, whether these complaints are right or wrong, well or ill founded, it is clear that they involve problems of a most vital kind as to the general effect upon the working classes of the conditions of modern civilization. To take the first head of complaint. If it be the case that a rise of rent or the charge for traveling be- tween the place of living and the place of work or similar ex- penditure is sufficient to deprive workingmen of the advantage of increased money wages, then the congregation of men in cities or in certain parts of cities, where higher money wages are to be obtained than elsewhere, which appear to be the conditions of modern industrial life, would be fatal to improvement. It would be the same with the necessity for working in an exhausting cli- mate. The problem, as stated, is certainly of the gravest kind. The questions raised by the second head of complaint are just as important. If increase of toil, not proportionately remuner- ated— for which perhaps there can be no proportionate remuner- ation— comes with the increase of productive capacity and the greater call thus made on the nervous and mental energy of the workman, what is the workingman the better off for all the civili- zation ? Finally, as regards the increased cost of living through a rise in the scale, may it not be the case that such a rise in the scale of living is to some extent what is meant by progress, though the drawback of the slavery of the workers, which some working- men appear to feel so keenly, remains.? How far is the " slavery " itself avoidable, so long as human nature is what it is, unless at the risk of all civilization perishing ? Such problems are obvi- ously of the deepest interest. The desire for leisure, for an ease to a severe strain, in all these complaints, is itself very striking, and may perhaps be held of itself to indicate a change of work- ing-class conditions, as compared with a time when the masses simply endured, or were content to drag on a dull existence, with little color in it, and without hope of change. The whole subject, at any rate, should be well worth considering. What are the facts, and what should be the conclusions regarding them ? Dealing with the first head of complaint, which is perhaps the simplest and most easily dealt with, we must allow it to be obvi- 652 THE POPULAR SCIENCE MONTHLY. ous on the surface that there is a real point for discussion. Under the essential conditions of modern life, principally the concentra- tion of huge masses on narrow room, competition among laborers undoubtedly produces monopoly rent, the payment of which is a simple deduction from the gross money wages which work- men receive. If workmen, to avoid paying more than they can help, live at a distance from their work, they only escape the evil partially, because charges for conveyance to and from their work have to be paid. Clearly workmen under such conditions, as com- pared with conditions under which no monopoly rent or its equiv- alent has to be paid, are at a disadvantage. To show their real position for the purpose of comparison, the monopoly portion of the rent must be deducted. It is quite obvious, also, on the merest superficial aspect of the question, that as regards many workmen, at least, the disadvantage may easily be so serious as to compen- sate, and more than compensate, all the difference between the money wage of the country, where there is no monopoly rent, and the money wage of the town. Take the case of a west Highland peasant fifty years ago, living on a scanty wage of a few shillings a week, or the produce of a poor croft eked out by kelp-gathering or fishing, and his descendant at the present time in the slums of a great city, earning perhaps fifteen shillings a week, but disbursing four or five shillings for rent. The improvement in money earnings may be immense, perhaps one hundred per cent, and as regards prices of commodities there may be no drawback in the change, but the rent takes a monstrous cantle out of the margin. Comparing all the conditions, it may certainly be doubted whether the peasant, in the case supposed, in exchanging the hard life of the country, which still had the advantage of being in the open, for the hard life of the city, has made any real advance. Take a case higher in the scale. A doctor, to earn a living, resides in a city rather than in the country, pays a huge monopoly rent to begin with, and incurs many other analogous expenses, so that altogether he has a large leeway to make up before he can reckon that net income which can properly enter into comparison with that of his country colleague. The difference may easily be so great, I be- lieve, that in many cases a professional man in a small country town with three or four hundred pounds a year may have a larger net income for the real objects of life, dealing with the question in a wise, philosophic spirit, than a professional man in London with a thousand or twelve hundred pounds a year. There are differences even between London and smaller provincial cities. Thus the question between gross and net, which workingmen have raised in these discussions, apropos of monopoly rent or the equivalent, is a real question. It is a new form of the old theo- rem that people may buy gold too dear. THE GROSS AND NET GAIN OF RISING WAGES. 653 I have already, in part, dealt with the question practically as far as workingmen are concerned, by pointing out the really narrow limits of monopoly rent,* and practically the final conclu- sion must be reached by the statistical method, and in the way I have already used. But I wish to avoid statistics for the present, and to indicate merely the general conditions of the problem to be solved, which appear to minimize the possible extent of the alleged drawback. It is clear, first of all, on general grounds, that the concentra- tion of men in cities is due to the fact that cities, on the whole, weigh in the balance against the country. There is more and better employment there than in the country, all deductions made, in the opinion of those interested ; and that seems a conclu- sive answer to the question as to whether, on the whole, there is not a net as well as a gross improvement in wages as far as this drawback is concerned. Next, it is plain that, as a great part of the improvement of the last fifty years has consisted in the substitution of artisan and other highly paid labor for merely rude labor, the additional monopoly rent payable in the cities can only be, in most cases, a comparatively trifling drawback. It may be the case that, if we compare the former peasant of the country with the rude laborer of the city, and especially of the metropolis, the latter has hardly gained; but if we compare the former peasant of the country with the town artisan of the present time, although the latter has to pay monopoly rent or an equivalent charge for conveyance, there is still an enormous gain in the latter's position. It is the same with the professional classes. If the latter were stationary in number, or increasing only pari passu with the increase of population, then the larger gross income on the average earned by the masses of professional men in cities, as compared with the professional incomes earned in the country formerly, might show little net improvement ; but allowance has to be made for the fact that the number of such incomes has enormously increased, and that the earners largely compare with the earners of wholly inferior incomes in former times, whether in town or country. As the increase of these classes could not have taken place with- out the growth of cities, there must be a large net as well as gross gain to be reckoned when the comparison is properly made. To bring the matter to a point, what I have to urge is, that the very growth of cities implies the existence of conditions under which workmen of higher grades take the place of work- men of lower grades, so that, although class for class a workman passing from country to town does not seem to gain so very much, on account of the difference between gross and net, yet, * See "Essays in Finance," second series, pp. 381, 382. 654 THE POPULAR SCIENCE MONTHLY. man for man, on the average there is an enormous gain. Illusion is produced because the proper terms of the comparison are lost sight of. The point is especially important as regards what is known as the residuum. Nothing can appear so deplorable or so hopeless as the conditions of the floating mass of rude labor in large cities. Monopoly rents in this case appear to sweep away all possible advantage which may result from higher money wage, comparing the laborer of the town with the laborer of the country. In many cases, even, it must be admitted, the " residu- ary " of the city is on a lower level than the " residuary " of the country. His " net " earnings are less. But the question, after all, is one of proportion. The absolute magnitude of the city residuum must not blind us to the fact that it may be, not an increasing but a diminishing element with reference to the pop- ulation generally. I believe it is a diminishing element, but this would hardly be the place to discuss the point, and I am content for the present to call attention to its importance in the discus- sion. The assumption, so often made, that the residuum is in- creasing relatively, is one which requires proof, and I have never seen any attempt at proof, while there are some broad facts, such as the diminution of serious crime and of pauperism, against it. The question of the way in which the net value of an increase of money wages may be affected by the necessity of living in a more exhausting, or in some way more expensive, climate, or by the specially exhausting character of a highly paid occupation, such as puddling, is one of the same kind. There is clearly a point in the matter for consideration and discussion. I am dis- posed to believe, for instance, that the exhausting climate of the United States, compelling the consumption of more food to enable the same work to be done, is a distinct drawback to the Ameri- can workingman as compared with his competitor in western Europe, and especially in Great Britain. I am not sure but that living in the south of England, owing to climate, is more expen- sive than in the north and in Scotland. The point has hardly been expressly considered, the workingman practically having been right to go where he gets the highest money wage, but it is one that may become of increasing practical interest now that charges for conveyance are so low throughout the world as to make it quite unnecessary for men to live near the places where their food and raw materials are produced. I shall be well con- tent for the present if the remarks here made induce some work- ingmen to elaborate it from their practical experiences. Of course, in any discussion it would also have to be considered that the greater expense of living may not be a pure drawback. The ability to consume and produce more, to bear exhausting climate or occupation, in fact, may be a good thing, and bring its own THE GROSS AND NET GAIN OF RISING WAGES. 655 compensation, although the net gain, taking matters strictly, may hardly be appreciable. The next head of complaint is the increase in the severity of labor and the want of any proportionate remuneration. On this head it may be admitted, to begin with, that there is apparent foundation for some of the complaints. Workmen in particular employments do not get a reward at all in proportion to the increase of production in those employments. The illus- tration of a cotton-mill is familiar. A single attendant on a num- ber of machines will " produce " as much in an hour as formerly in a year or two, but his wages are only double — or perhaps not quite double — what they were when the production was so much less. A great steamship supplies another illustration. The ship does many times the work which could have been performed by the sailing ship it has displaced, and with much fewer men in proportion to the tonnage conveyed. But the wages of the aver- age member of the crew are again only double, or not quite double, what they were when the conveyance done was so much less. In these and similar cases, who gets the benefit of all the increase of production ? The workmen in the particular employ- ments concerned, receiving only a fraction of the gain, may be excused for suspecting that there is something inexplicable in those social and economic arrangements by which the benefit is spirited away from them. But, however natural the question, it is not difficult to point out that there is a good reason why workmen in some given em- ployments should only receive a fraction of the benefit from the increased productiveness of those employments, and that this fact is quite consistent with an improvement in the position of work- men all round in proportion to the generally increased product- iveness of labor, which is the real question we are now investigat- ing, for the purpose of comparing this increase of productiveness with the increase of the severity of labor throughout society. The short explanation is that the employments in which there is a great increase of production, being mainly the employments in which there are great mechanical improvements from time to time, constitute only a part of the whole employment for labor, and that by a natural law labor in each employment finds its level, the increase of the return arising from an invention in a particular employment resulting in a gain, not to the particular laborers concerned, but to the whole community of laborers. That the gain may be general, it is, in fact, essential that laborers generally should gain as consumers rather than as producers, which implies that in a given employment wages should increase, not in proportion to the increased productiveness of that employ- 656 THE POPULAR SCIENCE MONTHLY. ment by itself, but in proportion to the increased productiveness of labor generally. Hence, it may well be that while the product- ive power of machines may enormously increase, yet the general increase of productive power may be much less than would at first be thought, owing to the comparatively small proportion of laborers, after all, who use machinery of great capacity largely in their employments. Looking at the number of domestic servants, of clerks, of professional men and women, of unskilled laborers of every kind, of skilled laborers, such as painters, who do not use machines, I should doubt very much whether one fourth of the laborers, even in a society like that of England, the most manufacturing in the world, use machinery of great capacity in their employments. It is easily to be accounted for, therefore, why in a given employment there should be a great increase of production without a corresponding increase of remuneration to those engaged in that particular employment. The gain has to be diffused through society, and the increase of production gen- erally is not so great, and not nearly so great, as in a few special cases. Another observation must be made. There may be a consider- able improvement in the quality of production in employments of a non-mechanical kind, which it is difficult or even impossible to note by quantities, but where the labor competes with all other labor for remuneration. Where the increased remuneration should go to, when machines improve, is not thus so easy to de- termine a 'priori. It is also obvious that even in an advancing community the remuneration of certain kinds of laborers, whose numbers con- tinue disproportionate, may either not increase at all, or increase very little, the whole gain from increased productiveness being for the benefit of the laborers whose own labor improves in qual- ity, apart from the fact that it is employed on more productive machines. Strictly speaking, unless there is a rise in the scale of living, accompanied by an improvement in quality all round, there is no reason why, in modern times, a man who can only drive a spade into the ground, or wheel a barrow, or carry bricks up a ladder, should receive any higher reward than similar labor- ers in former ages. The fact that such laborers are little better off is not inconsistent with the fact that workmen generally re- ceive a larger reward than in any former period. The way is thus cleared for answering the question as to whether the remuneration of labor has increased generally in pro- portion to the increased severity of labor. It can not be denied, first of all, that there is a great increase of the productiveness of labor itself, as well as a great increase of the absolute amount of remuneration. This is admitted on all THE GROSS AND NET GAIN OF RISING WAGES. 657 sides. The increase of production is the very fact which is as- sumed. Nor is the increase of remuneration denied — the only question is of the proportionate remuneration. Before passing from this point, however, I should like to dwell a little on the fact already referred to, of an improvement in the quality of non- mechanical labor, because, as this labor is largely the subject of direct exchange without much intervention of capital, the mere fact of improvement implies almost a proportionate increase of remuneration. At any rate, the laborers concerned get almost the whole benefit, because they exchange with each other. I refer to such employments as those of teaching, medical attend- ance, nursing, domestic service, dressmaking, and the like among the upper and middle classes. The increase of remuneration here may not be in proportion to the improvement of quality ; the game may not be worth the candle ; but, at any rate, the ex- changes are direct. Now, as to the fact of great improvement, I believe there is no doubt. Nursing, for instance, is said to be an entirely different thing in hospitals from what it was only fifteen or twenty years ago. Domestic service, as regards cooking, wait- ing, and other points, is also, on the whole, better, notwithstand- ing manifold complaints, just because of the general improve- ment in education and intelligence. The same with dressmaking. More intelligence and skill are everywhere applied, and in direct exchanges, without much intervention of machines or of capital. Next, it has to be considered, as regards the question of pro- portionate remuneration, that by the very mode of here stating the question, it appears that it is not so much a question of in- crease in the severity of labor generally, as of a change in the character of the labor. If the quality of labor has altered and improved in many directions, there is, in truth, no proper term for comparison between the present and former times. The im- provement of the quality of the labor, which is another name for the increased intelligence and energy of society, may not be pro- portionately remunerated ; but there is no means of telling. People would not go back to the conditions of a former society, where less intelligence and energy were required for a lower scale of living, even if they had the choice. The new advantages, with all their drawbacks, are accepted as part of a higher state. The complaints are to some extent a sign of the perpetual unrest of human life, and of the fact of improvement itself. There can equally be no doubt, looking at the matter in this way, that in certain directions there may be a very poignant and not unjustifiable feeling as to an increase in the severity of labor. This appears to be the case as regards employments which in- volve the watching of machines, the very employments where there is apparently the greatest increase of production and the vol. xxxvi. — 42 658 THE POPULAR SCIENCE MONTHLY. least proportionate increase of the remuneration of labor. The strain upon the nervous system, through the combined monotony of the employment and the constant vigilance required, are no doubt very often most severe, and are perhaps felt the more because the present generation is comparatively untrained. But the increased severity of toil, without proportionate remunera- tion, might be admitted in those special employments without altering the fact that remuneration has increased generally. What seems to have happened in these cases is, that the develop- ment of society imposes a heavy burden on a special class, involv- ing rapid change in the quality of its labor, to which it is hardly equal, but that the improvement in quality is part of the general improvement in society. The nervous power to stand monotony and supply the necessary vigilance and other moral qualities necessary for the supervision of machines may exist in greater abundance in the next generation, along with a continued im- provement in the quality of labor in non - mechanical employ- ments. It will, perhaps, be urged that the workman does not get a proportionate remuneration because the capitalist obtains for himself the increased product — the socialist argument. But the facts are all against this explanation. One of the most remark- able facts of recent years is the general decline in the return to capital. Capitalists from year to year have been willing to invest for a smaller and smaller return. We must assume, then, that if they have gained at all it has only been by the immense cheapen- ing of commodities, and labor has gained more than in propor- tion. This would appear to be the case : only the laborers who have gained, as we have seen, are. not specially those who are occupied about machines. The gain is generally diffused, and is received by laborers generally in proportion to the relative values of their work. Apparently the greatest gain has been among the higher artisan and lower professional classes — the very classes, it may be remarked, by whom the strain of modern life is felt the most intensely. The conclusion, then, is, that if the return to labor generally is not proportionate to the increase of the severity of toil itself, the reason must be that people are working for inadequate ob- jects. The game, in one sense, may not be worth the candle. The problem is another form of the very same problem that has been considered with reference to the payment of monopoly rents. On the whole, notwithstanding all the drawbacks of city life, there is some improvement which makes the payment of monop- oly rents worth while. People would not change back to the former conditions. So, on the whole, notwithstanding all the drawbacks of really severer toil, and the inadequacy of the addi- THE GROSS AND NET GAIN OF RISING WAGES. 659 tional remuneration, people would not change back. What has happened is really a revolution in the quality of labor and the general conditions of life. The net gain, in one view, is less than the apparent gross improvement, looking at the matter strictly ; in another view, the gain is so great as to make the present con- dition of workmen on the average incommensurable with their former condition. The two things are not on the same plane, and can hardly be compared. An important corollary seems to be suggested by these con- siderations. If there is so much doubt about the adequacy of the reward for the additional labor thrown on workmen by the con- ditions of modern society, is not that reward really a minimum reward ? In other words, may not the amount of production itself be conditioned by the energy of the workman, which is in turn a function of the food and other things on which he expends his wages, so that the quality of labor by which modern society is carried on would not itself exist if the remuneration were less than it is ? The complaint we are dealing with is that of the severity of modern toil, and implies that the workman is tasked to his full capacity, and can just do the work, so that the remuner- ation can not be reduced. And that this is really the case in many employments may be easily enough illustrated. It is quite certain that the driver of an express engine could not go through the very formidable labors he undergoes if he only had the food of the rude laborer of a former time, and only lived in the way that such a laborer used to live. He would not, under such conditions, have the energy or brain-power for the work to be done. It is the same with workmen in a factory who have to attend to many machines. The constant strain simply could not be endured if the workman had to live as the factory worker of a former time had to live. The present worker is really cheaper than the former worker, because he does more in proportion ; but, dear as he is, yet, in another respect, he may perhaps be viewed, according to a suggestion already made, as really engaged at a minimum wage — without which he could not do the work at all. This is not a question merely of a rise in the scale of living, though that ques- tion is intermixed with it. It is a question of the actual necessity on the part of the workman that certain things should be put into him, or supplied to him, as a condition of his doing the work which he actually performs. What is true of the workman spe- cially referred to is of course still more true of the higher kinds of work involving artistic or other skill. It may also be added that the suggestion already made as to the reason for a non-increase of remuneration in certain direc- tions being that the work done has not itself improved in quality, is fully confirmed by the general view thus stated. If the work 660 THE POPULAR SCIENCE MONTHLY. which has improved in quality is itself only so remunerated as to make it doubtful whether the remuneration is adequate, whether the game is worth the candle, and is, in fact, at the point of mini- mum, so as to enable the work to be done at all, out of what fund is the remuneration of the work that has not improved in quality to come ? In the midst of plenty, apparently, such workmen, by comparison, must starve, because, notwithstanding all the plenty, those who really do the hard work of modern society are only just paid, and no more. It is easy for such workmen and their so-called friends to point to the capitalists as living on their labor ; and no doubt, if it were possible to divide the earnings of capitalists among society generally, according to numbers, these particular workmen might be much better off. But it is not from the labor of such workmen that capitalists mainly derive their income, while those who do work, as we have seen, have so large a remuneration that they can have no quarrel with the capitalist. The suggested division would therefore only be for the benefit of a special class whose existence is itself a danger to society, and which should rather be discouraged than encouraged, the whole efforts of society being rather directed to their transformation by education and similar agencies into a higher class, than to securing an increased payment for their work under present con- ditions. The curse of the very poor, in more senses than one, is their poverty — poverty in strength, in mental capacity, in moral qualities. They are poor because they can not earn more. If they were stronger they would have the earnings, and would have no quarrel with the capitalists. To improve their condition they must be made stronger, and not merely given more to spend, which would be a curse to them instead of a blessing, as it is to the merely idle capitalist whose luxury they envy, whose exist- ence is a danger to society also, and whose obliteration, or rather transformation into a different class, is equally to be sought for. The next head of complaint is that a workman has more ex- penses now, in consequence of the rise in the scale of living. Not only himself, but his family, must live better. They must have better and more food, be better clothed and sheltered, be better educated, and so on. The workman himself, on whom the burden falls, has no more surplus than before. He is not a freer man. This head of complaint, however, demands very little remark. The statement of the complaint is, in truth, one of the best evi- dences of progress. Of course, there has been a rise in the scale of living. Such a rise was quite certain to come with an improve- ment in the earnings of workmen. The fact that it has come is itself one of the proofs of improvement. No doubt there is a con- tinued absence of a free surplus. I suspect, however, that at no time have many people, in this country at least, had philosophy THE GROSS AND NET GAIN OF RISING WAGES. 661 enough to be thrifty and careful, and to do without some things that appear to be necessary for their sphere in life, so as to have what is meant by a surplus. Its absence is certainly no proof that the condition of those who make the complaint has not improved. The scale of living has risen, and this rise, beyond all question, imposes a strain upon many workmen which only the greatest care and philosophy can mitigate. It involves of necessity severer toil on the part of the bread-winner, with no apparent surplus for himself. It is apparent, however, that to some extent what is called a rise in the scale of living is, in reality, an improvement in the mode of living which is absolutely necessitated by the work itself, without which, in fact, the work could not be done. Where moral qualities are to be displayed, and great vigor, punctuality, and energy are required, they are not to be expected except from workmen of a certain class, whose scale of living has, in fact, risen to the standard necessary, and whose " medium " and " at- mosphere," of which the condition of wife and children or rela- tions is a part, are altogether different from what they were. Be- fore human beings can display the qualities and exert the energies required, they must have certain tastes and wants to gratify, or there would be no motive to exhibit those qualities and en- ergies. Hence a rise in the scale of living is only another mode of describing the improvement in the character of the workman, which is essential to the performance of the work to be done. The conclusions of this long argument may now be very shortly restated. In certain cases the increase of net earnings by the advance of the last fifty years can not be so great as the in- crease of gross earnings, because some classes of workmen have to submit to an increased charge for rent and railway fares, and similar expenditure, which really amount to a reduction from the gross earnings which they receive. But, on the whole, the classes of workmen affected in this way must, from the nature of things, be comparatively small, while the general conditions are such that the deduction from gross earnings, as a rule, still leaves an enor- mous net gain. Next, the allegation as to the increased severity of labor, and as to workmen not getting a sufficiently ade- quate remuneration or a sufficient share of the increased gross produce, is met by the admission generally of an increase in the severity of labor, which, however, is found to be more properly described as a revolution in the quality of the labor, and to be connected with the fact of improvement generally, and to be evi- dence of improvement in the workman's condition. The character of labor generally has so changed that it can not really be meas- ured in comparison with the labor of a former time. Some work- 66z THE POPULAR SCIENCE MONTHLY. men engaged about machines may appear to get comparatively little of the increased production for themselves, but the reason is that the improvement in machines is for the benefit of society as a whole, and not specially for that of the particular workmen engaged upon them, who only participate in the improvement as consumers, and not as producers. Substantially, however, there is more severe toil all round, and whether the additional remuner- ation is adequate or not, the change in the quality of the labor is necessary to the production, the laborer gets all the possible re- muneration, and the labor itself could not be carried on without the remuneration obtained. It is the same with the complaint as to the rise in the scale of living. The rise in the scale is at once a proof of the improvement in the workman's condition, and of the necessity for an improvement in his living to enable him to do the new work. The two things are inextricably connected. On the whole, the complaint of workmen as to the difference be- tween gross and net is not unjustified, but it points to changes in their condition of a remarkable kind, which are in every way de- serving of further study. To show fully what these changes are, statistics would be needed, but the necessary conditions of the prob- lem are apparent without statistics. The complaints here dealt with could not exist without that improvement in society and the con- dition of the masses which the complaints seem to call in question. A further conclusion may be drawn. The conditions of life thus indicated seem favorable, on the whole, to a continuous im- provement in society, so long as science and art make progress, and heavier and heavier calls are made on the intelligence and energy of workmen, along with an increase of their capacities on the one side and their wants on the other. The whole structure of modern society is such as to require greater and greater knowl- edge, greater and greater energy and moral power, greater and greater capacity of every kind, so as to make sure that machines and inventions are maintained and improved, and that artistic capacities and the arts of living are developed to correspond. The continuous improvement implies a continuous improvement, on the average, of the human being who really belongs to the new society. So long as society, therefore, continues to progress — that is, for our present purpose, so long as the average workman con- tinues to produce more quantity or better quality — there must be continuous improvement and progress in the quality of workmen themselves and the conditions of their existence, although we should not expect that complaints would cease as to the greater severity of toil and as to particular classes of workmen not getting for themselves the full benefit of the increased production. Still, the improvement is there, and the complaints, when analyzed, are, in truth, signs of the improvement. CONCERNING SHREWS. 663 The one doubtful sign, it appears to me, as regards the future, is pointed at by the qualification implied in the words — the human being ivlw really belongs to the new society. It may possibly hap- pen that there will be an increase, or at least non-diminution, of what may be called the social wreckage. A class may continue to exist and even increase in the midst of our civilization, possibly not a large class in proportion, but still a considerable class, who are out of the improvement altogether, who are capable of noth- ing but the rudest labor, and who have neither the moral nor the mental qualities fitted for the strain of the work of modern society. On the other side, as already hinted, the existence of what may be called a barbarian class among the capitalist classes, living in idle luxury and not bearing the burden of society in any way, seems also a danger. But speculations of this sort would perhaps take us too far at present. Substantially, as yet, there seems to be ho reason to doubt the steadiness of the improvement in recent years among the working classes, both those practically so called and those who may be included when we use the lan- guage in its widest — that is, the strictly economic — sense, and that this improvement goes on from year to year, and from gen- eration to generation, and must, in the nature of things, go on, in consequence of the improvements and inventions of the modern world and the general spread of education, so long as nothing- happens to prevent a continuous improvement in the efficiency of human labor and the average return it can obtain from the forces with which it works. — Contemporary Review, CONCERNING SHREWS, Bt frederik a. fernald. THE shrews, or shrew mice, as they are often called from their mouse-like size and general appearance, are nearly related to the moles, but may be distinguished from them by their distinct outer ear and the moderate size of their fore-paws, which are not usually employed in digging. They have a long, pointed muzzle, with two very long cutting teeth in each jaw — the upper much curved and the lower nearly horizontal. Their other teeth are many-pointed, being thus adapted to seizing the worms and crushing the hard wing-cases of the beetles which form their food. They also sometimes destroy small vertebrates and devour each other. Most species of shrews live on the surface of the ground, and a few in burrows. They do not hibernate. They take their food at night. They are spread over the northern hemisphere, sometimes going very far north, and the smaller spe- 664 THE POPULAR SCIENCE MONTHLY. cies enduring severe cold. The sub-family Soricina is the only one represented in North America ; other sub-families are found in Europe, Asia, the East Indies, and in south and central Africa ; none as yet have been detected in South America. Most of the American species belong to the genus Sorex (Linnseus). Prof. Spencer F. Baird described twelve species, varying in length from three to four and a half inches, in Vol. VIII of the Pacific Pail- road Reports. In color they range from blackish and brownish to grayish above and lighter to whitish beneath. Most of the species belong on the Pacific coast or in the Northwestern States and Ter- ritories. The 8. personatus is the least of the American shrews, and among the smallest of the quadrupeds of this country, being not . quite three inches long ; it belongs in the South Atlantic States. In the genus Blarina (Gray) the body is stout, the tail shorter than the head ; the skull is short and broad, and the fore-paws are large in proportion to the hind- paws. This genus is peculiar to America. The mole shrew (B. talpoides, Gray), the lar- gest of the American shrews, four and a half inches long, is found from Nova Scotia to Lake Superior, and south- ward to Georgia. It is dark, ashy gray above and paler below, with whitish feet. Several other species are described by Baird, of which two are in Mexico and Texas. Four species of shrew are mentioned by Wood as inhabiting the British Isles : the erd shrew, the water shrew, the oared shrew, and the rustic shrew. The erd shrew, also called the shrew mouse, is the common shrew of England, and is found also all over Europe, Unlike most animals, they are often found dead ; though, owing to their nocturnal habits, they are seldom seen alive. Aubyn Battye writes in " Longman's Magazine " : " Every countryman is familiar with the sight of shrew mice lying dead on autumn footpaths and by sides of roads. The hot, dry English September weather presses very hardly on this class of animals. Worms retire then a long way below ground, and even the strong mole often can not follow them in the hard-baked ground, and has to trust to slugs for maintenance. The damp, dead leaves of the hedge-bottom, which were once the shrew's best hunting- ground, are dry and deserted now — a fatal change of things. Yes, dead we often see the shrew ; and picking him up we hold in Fig. 1. -Mole Shrew. CONCERNING SHREWS. 665 our hand a little creature of an oddly quaint and old-world ap- pearance, with a coat like velvet, brownish black above and gray- ish white beneath. But the two ends of him strike us most ; a long, pink-tipped snout, and a blunt, four-sided tail." Shrews are accustomed to eating much and often, which doubtless accounts for their dying so speedily when food becomes scarce. The reason why their bodies are seen lying about instead of being devoured by flesh-eating creatures is probably because they secrete a strong scent that does not seem to please the palate of cat or weasel. Cats will catch them to play with, and finally kill them, but will not eat them. Owls eat them, however, and so does the kestrel falcon. On account of this scent, the animal is known in some parts of England by the name of fetid shrew. In Scotland it is called the ranny. The Latin term araneus, or spider-like, has been applied to this creat- ure by several writers, be- cause it was said to bite poisonously like a spider. The body of the shrew is not much over two inches long, and its whole length from the snout to the tip of the tail is about four inches. It lives in little tunnels which it digs in the earth, and which serve also as a hunting-ground. The nest in which the young shrews are brought forth is not made in the burrow, but in some little hollow or a hole in a bank. It is composed of leaves and like substances and is entered by a hole at the side. The young are from five to seven in num- ber, and are generally born in the spring. The word shrew applied to a scolding woman has a different derivation, according to the dictionaries, from the name of our little insect-hunter. But it is no libel on the animal to give its name to a vixen even of a more unconquerable sort than is rep- resented in Shakespeare's " Taming of the Shrew," as the follow- ing character which "Wood gives it abundantly shows : " Sometimes the shrews mutually kill each other, for they are most pugnacious little beings, and on small ground of quarrel enter into persevering and deadly combats ; which, if they took place between larger animals, would be terrifically grand, but in such little creatures appear almost ludicrous. They hold with their rows of bristling teeth with the pertinacity of bull-dogs, and, heedless of everything but the paroxysm of their blind fury, roll Fig. 2.— Common European Shrew (Sorex araneus). 666 THE POPULAR SCIENCE MONTHLY. over each other on the ground, locked in spiteful embrace and uttering a rapid succession of shrill cries, which pierce the ears like needles of sound. It is a most fortunate circumstance that the larger animals are not so vindictively pugnacious as the moles and the shrews ; for it would be a very hard case if we were unable to put two horses or two cows in the same field without the certainty of immediate fight, and the probability that one of the combatants would lose its life in the struggle." The bite of such a little creature obviously need not be feared by a human being, though ancient prejudice attributes to it such venomous properties that in many districts in England the viper is no more dreaded than the shrew. Even the touch of the ani- mal's tiny foot was believed to cause pains which could only be relieved on the " like cures like " principle. The following curious account of this latter superstition is from Gilbert White's " Natural History of Selborne " : " At the fourth corner of the Plestor, or area, near the church, there stood about twenty years ago a very old, grotesque, hollow pollard ash, which for ages had been looked on with no small veneration as a shrew ash. Now a shrew ash is an ash whose twigs or branches, when gently applied to the limbs of cattle, will immediately re- lieve the pains which a beast suffers from the running of a shrew mouse over the part affected ; for it is supposed that a shrew mouse is of so baneful and deleterious a nature that wherever it creeps over a beast, be it horse, cow, or sheep, the suffering animal is afflicted with cruel anguish, and threatened with the loss of the use of the limb. Against this accident, to which they were continually liable, our provident forefathers always kept a shrew ash at hand, which, when once medicated, would maintain its virtue forever. A shrew ash was made thus : Into the body of the tree a deep hole was bored with an auger, and a poor devoted shrew mouse was thrust in alive and plugged in, no doubt with several quaint incantations long since forgotten." The shrew is often seen near reposing cattle, and this habit probably gave the chance for putting upon it any unexplained malady that the cattle might suffer. But it has been well sug- gested that the shrew goes to domestic animals for the insects which light upon them. From the fact that the shrew will eat one of its own species, if slain in battle, it is evident that insects and worms do not form its whole diet. " One of these little creat- ures," says Wood, " has been discovered and killed while grasping a frog by the hind-leg ; and so firmly did it maintain its grasp, that even after its death the sharp teeth still clung to the limb of the frog. Whether the creature intended to eat the frog, or whether it was urged to this act by revenge or other motive, is uncertain." CONCERNING SHREWS. 667 The water shrew is much like the erd shrew in general appear- ance, but its fur is nearly black on the upper parts of the body, instead of the reddish-brown color which marks its relative. On the under parts its fur is beautifully white. The fur is very silky and has the useful property of repelling water. When swimming, the parts of the body which are submerged appear to be sprinkled with tiny silver beads, which give the animal a very brilliant appearance. This phenomenon is due to air-bubbles that cling to the fur. Water shrews are fond of pools and streams that are pretty well open to the sunlight. The following account of them is given by the writer in " Longman's," already quoted : " See these water shrews, how they chase one another in the pool ! Out of the water their fur is black and soft, but under it a thousand air-bubbles clothe them round till they flash like silver fishes in the sun. In and out of the weeds they swim, picking off the fresh-water shrimps from under the leaves. No sea otter is more at home under the water than they. Yet are their feet not webbed, but only fringed about with stiff white hairs. Instead of swimming with the direct mo- tion of the water rat, the water shrew appears to move alternately both its feet on either side. Unlike the common shrew, which rears its young near the surface of the ground, often in the old nest of a field mouse, the water shrew nests in holes under the bank. It generally, I think always, appropriates some existing hole, which it no doubt improves to. its liking." kss^SfeVc* v"U- Fig. 3.— Water Shrew (Crossopits fodiens). Besides catching aquatic insects, the water shrew roots out larvae from the muddy banks with its long snout, and does not hesitate to eat moths and other like insects which fall into the water and drown. The ears of this creature are peculiarly adapted to prevent the entrance of water. When it goes beneath the sur- face, the pressure of the water folds together three small valves, which effectually close the opening of the ear. " The total length of the water shrew is not quite four inches and a half, the length 668 THE POPULAR SCIENCE MONTHLY. of the head and body being a little niore than three inches, and that of the tail being about two inches. Its snout, although long, is not quite so narrow and pointed as that of the erd shrew, and its ears are remarkably small. When it swims, it has a curi- ous habit of spreading out its sides, so as to flatten its body as it floats upon the water" (Wood). Another kind of shrew which frequents the water is the oared shrew, so called from the oar-like shape of the feet and tail. It- is the largest of the British shrews, its total length to the tip of the tail being about five inches and a quarter. The fur on its back is sprinkled with white hairs, and that on the flanks and belly is blackish gray, tinged with yellow. On account of the general dark appearance of its fur, it is sometimes called the "black water shrew." The rustic shrew (Corsira rustica) is found in many parts of England, while in Ireland it replaces the erd shrew. The smallest mammal known to exist is found among the shrews. This is the Etruscan shrew, and it is found in Italy. Its head and body measure only an inch and a half in length, and its tail adds about an inch more. A CHEMICAL PROLOGUE. By C. HANFORD HENDERSON, PROFESSOR OF PHTSICS AND CHEMISTRY IN THE PHILADELPHIA MANUAL TRAINING SCHOOL. THE human infant, during the first few weeks of its life, must be regarded simply as a bundle of possibilities. A bright light, a loud noise, an appreciable degree of heat or of cold, pro- duce, it is true, corresponding reactions. The child blinks, or it starts, or it shrinks, and there is manifest to the most careless ob- server a general sense of uneasiness. But these reactions must be regarded as purely involuntary. One can not discover in any of them the presence of thought. There is no co-ordination of the faculties. The touch includes anything that may come within reach. It does not act in any way in harmony with the eye. Nor does the gaze become fixed upon any object. The eye wanders from one thing to another without really seeing anything. Simi- larly with the sense of hearing. Sound is a mere vibration, without any meaning whatever. If it be sufficiently loud, it makes the infant start much as a violent explosion would shake a window or rattle a pile of dishes. But as the weeks roll by, there comes a marked change. When the child reaches the age of three months the presence of will be- comes unmistakable. The faculties begin to act in harmony with A CHEMICAL PROLOGUE. 669 each other ; or, as we are apt to say, the child begins to take no- tice. Then it is that the birth of the human soul into the little body becomes apparent. The child is observed to fix its gaze upon objects. It begins to recognize faces ; it begins to see ; it begins to hear; it begins to feel. In a word, intelligence has dawned. The years succeeding infancy are full of incident. Each day is crowded with new experiences and new sensations. Years pass before the most obvious of these are exhausted of their interest. The child reaches out its hand for the moon ; it finds delight in the glancing sunbeam ; it is surprised by its own reflection in the glass ; it is charmed by all forms of rapid motion ; it dances glee- fully before the fire ; it is made curious by the rustling of a leaf, The little man is full of the spirit of investigation. He is a true experimenter. He is constantly putting questions to Nature, and, after a fashion, he is finding answers. He awakens to conscious- ness in a world that is for him full of wonders and surprises. There is no truer fairy-land than that in which he daily moves. The ever-present mystery ; the delightful sense of anticipation ; the persistent belief in the impossible, make childhood — in spite of its little worries and absurd fears — a veritable paradise, from which advancing years, like the angel with the flaming sword, casts us out all too soon. The activity of the child is exceedingly interesting in the ab- stract ; perhaps a little inconvenient in the concrete. He throws a goblet on the floor, and is as much amazed that it should break as the owner of the goblet is annoyed. It is a destructive age, and is apt to meet with but little sympathy from older persons who for- get that they have gained their own store of knowledge from just such a series of adventures. Children willingly sacrifice a toy to learn what it is made of, and I am disposed to think that the knowledge so gained is worth more thanflt-he plaything. And so the first years of life are spent in becoming acquainted with sur- rounding objects. The days are very full of pleasure when one is acquiring knowledge in this simple and natural fashion. All of us have gone through these experiences. By hundreds of tests — pleasant and otherwise — we have learned that certain substances are brittle or tough ; are hard or soft ; are rigid or flexible ; are light or heavy. By repeated falls we have gained some notion of gravitation — that bodies unsupported will fall to the ground. Burned fingers have taught us that flame and fire are hot. Torn jackets have shown us that there is a point beyond which we can not go and expect cloth to resist strains. It is in this way that we have gained our stock of common knowledge. Experience is undoubtedly the best teacher. When maturity is reached, all have gained the greater part of this common stock, and the 67o THE POPULAR SCIENCE MONTHLY. affairs of everyday life proceed upon the very reasonable suppo- sition that such knowledge may be taken for granted. But the question arises as to whether experience shall be permitted to end here, and so superficial a knowledge content us. It has been good for man to learn these more common truths. Would it not, then, be well for him to carry the search somewhat further, and to learn facts less commonly observed, as well as to investigate as far as he is able the cause and significance of all phenomena ? There is but one answer : it is overwhelmingly affirmative. It is to this problem that science addresses itself. The value of a study so intimately connected with the conduct of life is attracting an increasing number of students. The old battle be- tween science and the classics in college curriculum does not need to be waged over again. Generations devoted to the pursuit of language have at length evolved a people in whom facility of ex- pression is hereditary. The lack of something to say alone pre- vents universal authorship. The youth of the present day ask a discipline more inspiring than that offered by grammar and lexi- con. It is found that the mind can be both instructed and trained without first killing the natural curiosity and interest of the pupil. It is true that there is a college near Philadelphia where a young woman is not even permitted to take a special course in biology unless she has an intimate knowledge of at least three foreign tongues, but happily such absurdities are rare. As a rule, the colleges and universities of the country have responded generously to the demand for broad scientific culture. In that field the battle has been won. But a little leaven leaveneth the whole. Beginning at the top of our educational system, the tend- ency toward scientific study is gradually making its way down to the very Kindergarten. It would be still more general, and would be a larger factor in individual life, were that important truth re- alized which Mr. Herbert Spencer has so often insisted upon, that scientific knowledge is simply a higher development of common knowledge, and means only more accurate and more extended thinking about our environment. And so, in science, we are to become again as little children, and put more questions to our great mother, Nature. The results of this renewed questioning will not be trivial. They serve a dual purpose. They bring a much enlarged expe- rience, and discover to us the relation between widely different phenomena. By the one service, the confines of our apprehended universe are expanded to such magnitudes that they demand for their occupancy the highest intellectual effort of which man is capable. Through the other, no confusion results from this im- mensity. It is a world of harmonies and relations. Man feels himself not oppressed, but inspired, by such a contemplation of A CHEMICAL PROLOGUE. 671 Infinity. He is one both with that star-beam which left its home before America was discovered, and with the blowing flower which a breath of summer has called forth. It is no mean van- tage-ground, nor one which the spectacled haunter of libraries can afford to despise, to feel one's self a sharer in the pulsating life of the universe, to be a citizen of space, at home everywhere. Such is the position of the earnest scientist. He is the true poet and the true prophet. He lives in communion with a God who is the same yesterday, to-day, and forever ; in whom there is no variableness, neither shadow of turning. This absolute confidence in the inexorableness of divine law begets a serenity of life which is with difficulty disturbed, and a deep morality of thought and deed which is seldom the child of more local revelation. The idea of chance or caprice becomes impossible. " All's love, but all's law." It is with a curious pity that the student of Nature watches the crowd of worshipers at the Tower of Babel. He is willing to admit, with Max Muller, that there is no thought without lan- guage, and no language without thought ; but so pre-eminent seems the thought to him that he feels well assured that a suit- able vehicle will not be wanting for the carriage of so royal a guest. To such a one, the conduct of life becomes the chief end of education. The crucial test which he applies to each branch of study offered to either young or old is not whether it is useful, but whether it is the most useful. He will not be satis- fied with any choice that is merely second best, for time mean- while is flying, and, if we do this, we can not do that. The question is not whether any particular course will bring wealth of infor- mation, but rather whether it will induce fullness of living. It is surprising with what a small stock of facts, if they be of the right sort, a man can get along, and still be happy and progressive. I remember, as a boy, the envious regard which I bestowed upon a little friend of mine, whose dexterity in the difficult art of parsing quite surpassed my own feebler efforts. But one day I made the discovery that not only was he no better for entertaining that sort of knowledge, but, what was more surprising, his English was no more polished than my own. Since that time I have had frequent occasion to recall the discovery, and I confess that it has recon- ciled me to an ignorance upon many similar subjects. The sub- stitution of this artificial, lifeless knowledge for that which is natural and organic, must be regarded as scarcely less than crimi- nal by those who hold the true aim of culture to be the evolution of wisdom and of goodness. A man can not be expected to think soundly about a world of which he is quite ignorant, or to bring himself into relation with a universe whose confines are nearer than his finger-ends. 672 THE POPULAR SCIENCE MONTHLY. It is true that scientific education may fail quite as dismally as the classical has in times past if the grand generalizations of science are to be obscured by its manifold details. Emerson has somewhere said, " Men are so prone to mistake the means for the end that even natural history has its pedants who mistake classi- fication for science/' As a detached fact, the knowledge that water is composed of hydrogen and oxygen has no value. It is only when brought into relation with other chemical facts that it becomes significant. The statement found in elementary physical geographies and geologies that nine hundred and seventy-seven thousandths of the earth's crust consist of the nine elements — oxygen, silicon, aluminium, calcium, magnesium, sodium, potas- sium, iron, and carbon — carries very little instruction with it un- less the children know the substances of which these names are the symbols. Mere classification is a weariness of the flesh. Sci- ence has no greater lesson to teach than roots and case endings have, unless it be linked to human life. Nor must it be pursued externally ; it must touch our own experience, and its truths be- come a part of us, to be remembered because they can not be for- gotten. This is knowledge, and nothing less than this deserves the name. It is not so difficult to make even the more profound scientific studies touch intimately our daily life as one would imagine who has been taught to mistake classification for science. It is true that the multitude of objects which come within the field of sci- entific research require for their distinction a nomenclature which is not brief, but the student needs only a small part of it in the beginning. His vocabulary will grow with the using. In his "American Addresses" Prof. Huxley says, "For the purpose of getting a definite knowledge of what constitutes the leading- modifications of animal and plant life, it is not needful to ex- amine more than a comparatively small number of animals and plants." This, indeed, is the distinctive method of science. The student is made to advance from the particular to the general. The result justifies the method. By knowing a few things well, one knows everything, for one can not know even a few things well without having discovered by that very study the essential unity underlying all things. Our great geologists are not those who have " done " the earth, but rather those who have patiently and persistently studied a very small corner of it. To this rational mode of study all sciences are unmistakably coming. From its very nature, chemistry has been among the last to fall into line. It has been held, and in most quarters is still held, that the num- ber of substances studied by the chemist should be limited only by the span of life. In accordance with this view, the young stu- dent, instead of being allowed to make friends with a few of the A CHEMICAL PROLOGUE. 673 elements and really inquire into their secrets, lias been hurriedly introduced to all of those available, and has been left to struggle as best he could with their multitudinous compounds. The result has been to confuse, and in many cases finally to disgust. Chem- istry— and I do not wonder at it — has been voted " dry " by the majority of college boys. This result has come about because the science has been unsci- entific. The meaning of science is to know, but one knows very little from such a gallop among the varied forms of matter. If one knows thoroughly two or three typical gases, two or three typical liquids, and two or three typical solids, he knows chemis- try. He may not be worth much as a reference-book ; but then encyclopedias are nearly always available, while thoughtful men are rare. Further, the quality of such knowledge deserves atten- tion. It has become a part of the man himself, for he has learned it the way children learn things. It is no longer simply a fact of chemistry; it is a fact of life, a part of the oft-repeated expe- riences which go to make up his intelligence. Imagine for a moment the amusement of a bright boy were he asked whether he remembered if stones are hard, or lead heavy, or glass brittle. His answer will be that of course he does not ; he knoivs that they are. It is knowledge of a similar definiteness that the scientific method strives to cultivate. Studied in this way, chemistry ceases to be a matter of simple memory, and becomes almost exclusively a branch of pure reasoning. It passes from the objective to the subjective world, and becomes a valuable means of mental de- velopment as well as a study now well worth pursuing for its own sake. One of the first requisites, then, in the proper presentation of chemistry seems to be the entire banishment of that alien element which makes it a thing by itself, and the insistence upon its recog- nition as a purely natural extension of common knowledge. Any experience in life will form a suitable starting-point. It may readily be analyzed into its components ; the chemical element can not well be missed. If the occurrence be such as we com- monly call accidental, or, more strictly speaking, if it be devoid of human agency, it will resolve itself into two terms, conveniently expressible by the words matter and motion. If the occurrence be voluntarily producible, a third element is involved — that of will. It would be foreign to the present purpose to enter the vexed discussion of whether this third element, this unknown something which makes the distinction between conscious and unconscious existence, is the cause or the result of those reactions in matter and force with which will, as we know it, seems to be indissolubly connected. It will be sufficient for the present to call it x, a designation involving neither issues nor compromises. vol. xxxvi. — 43 674 THE POPULAR SCIENCE MONTHLY. Any common event, then, which may be selected by way of illus- tration, will furnish two elements open to scientific study — matter and motion. The distinction between the two is more convenient than essential, for we are unacquainted with matter devoid of motion, and the idea of motion divorced from matter is similarly unthinkable. However, the distinction is convenient, so that it will be well to follow it. The study of the analysis and synthesis of matter is the field of chemistry. The study of those varied motions which give to matter its apparent properties belongs to the domain of physics. The two sciences are commonly made the objects of separate study. It would be more true to nature to consider chemistry simply as a branch or subdivision of physics, for it is impossible to make any change in the constitution of matter without at the same time disturbing the physical equilib- rium. Heat is either given out during the reaction or it is taken in. If it be chemical combination, heat is commonly disengaged ; if a chemical disunion, heat is commonly involved. So general is the truth of this statement that we are able to predict what will occur chemically if the physical conditions are known. If there be two or more reactions possible, that one will take place which will liberate the greatest amount of heat. It is, indeed, the dis- tinctive character of the so-called New Chemistry that it takes cognizance of the physical reaction which invariably accompanies the chemical. If the labors of Crookes, Roscoe, Hunt, and other eminent contemporary chemists count for anything, it is from such joint study as this that the best secrets of chemistry are to be evolved. With the view of lessening difficulties, this necessary interdependence between the chemical and physical is frequently omitted in presenting the science to young students ; but the prac- tice of teaching errors or half-truths, in order that the truth itself may afterward be apprehended, has as little excuse in science as it has in religion, for generally it is the error which proves obdu- rate, and the subsequent truth has no chance whatever. It robs the science, moreover, of an element of vitality which is one of its chief attractions. In selecting our illustrations of chemical action, the more commonplace the event the better. The affairs of every-day life present such excellent objects for study that it would be as un- necessary as it would be uselessly distracting to go in search of the unusual, until the fundamental principles have been learned from a study of that which is familiar. That coal will burn, that milk will sour, that iron will rust, that cider will turn into vinegar, and that wood will decay, are all well-known facts of every-day life. But they are also facts of chemistry, for they in- volve a change in the composition of matter. It needs no scientist to perceive that the original coal, milk, iron, cider, and wood have A CHEMICAL PROLOGUE. 675 disappeared as such, and that new substances with totally differ- ent properties have taken their place. Yet this is all that a chemi- cal reaction means. It may be studied any day in the kitchen. The question of heat is quite as obvious. The coal has been burned for that very purpose. At first sight these several facts seem entirely unrelated. They have been selected quite at ran- dom. A moment's consideration, however, will show that these reactions, though seemingly dissimilar, are essentially identical. Your cook may not be able to explain them to you, but she can tell how they may be prevented, and that will serve the purpose equally well. Her answer will be the same for all : Keep the air from them. A fire with all the draught closed off goes out. Her- metically sealed milk keeps fresh. Painted iron does not rust. Bottled cider remains cider. Wood, not exposed to the air, will endure for centuries. So, after all, the common element in these reactions is not difficult to find. It is manifestly the air, for, in the absence of that, they do not occur. To the chemist they are all cases of oxidation. If he wishes to prevent them, he does just what the cook does — he keeps the oxygen of the air away from them. That is all that Mr. Edison does when he pumps the air out of the bulb of his incandescent electric light, so that the little carbon horseshoe shall not burn up. Now, there is nothing occult about all this. The examples given are not sufficient in number to warrant any very broad generalization, but they can readily be extended, and conclusions of universal application reached without other resource than that found within one's self. Beginning in the home, one's conclusions will be found to extend to the town, to the county, to the State, to the world. One may finally think about the universe. The spirit in which these investigations are conducted will be that of an inquiring child. It is literally true in science that " a little child shall lead them." The men who have built it up have labored successfully in exact proportion as they have put their questions directly to Nature rather than to books and to the sages. The most hopeful sign that the growing scientific mind can disclose to its fellows is that increasing simplicity of heart and mind which has characterized all the immortals recognized by science. It is this very faculty that has made men of science so notoriously incompetent in business matters. We have come to expect little news from a sharp bargainer. Questioning Nature in this childlike and natural fashion, life becomes again a daily revelation, and inspiration a contemporary event. It is paradise regained. There are still suffering and sor- row, but there are also their antidotes, hope and faith. There is universal law, but there is also universal love. The severe har- monies of the universe lend grandeur and dignity to the pass- 676 THE POPULAR SCIENCE MONTHLY. ing moment. One feels that the destiny of man is assuredly noble. The student will not go far in his quest before facts begin to accumulate which are fraught with the deepest significance. He has known perfectly well all along that only a certain amount of heat can be obtained from burning a definite quantity of coal, and that it will be given out in proportion to the rapidity with which the burning is accomplished. If he wishes his room to be warmer, he opens the draught and gives a more abundant supply of air to the fire. The operation has been too often repeated to excite any wonder. But it becomes significant when he discovers that all other chemical reactions rest upon precisely the same principle. Each substance is found to have a definite combining power, and in every reaction, however simple or complex it may be, a definite quantity of one element unites with a definite quantity of another. If too much of either element be taken, it will be left over. But this is the law of definite proportions discovered by Dr. Dalton in the early part of the century and now the very corner-stone of chemical science. If the student further inquire what has become of the coal and the oxygen whose union we call combustion, he will find that a colorless gas, carbonic-acid gas, has been formed whose weight is exactly equal to the sum of their weights. Other illustrations will yield parallel results, and the far-reaching con- clusion will be forced upon him that man is neither able to create matter nor to destroy it. This single truth once really appre- hended gives a stability to thought which can scarcely come from any other single consideration. The universe is seen to be in an eternal ebb and flow, but its materials are seen to be constant. Once persuaded of the fact, and the suspicion arises that the same may be the case with heat and other forms of motion. And such he finds to be the truth. He learns that energy likewise is neither creatable nor destructible, and that all the work going on in the universe is simply that of transformation. New distributions of motion and new combinations in matter, these make up the cosmic life, but the sum total in each case remains unaltered. Perpetual motion is seen to be more than a possibility ; it is found to be a necessity. One sees all of the universe in a state of ceaseless flux, sees that nothing stands still, that growth involves never-ending change, and becomes prepared to accept without fear those changes of opinion which intellectual growth necessitates as well as that great change of state which we call death. I can not hold as idle or of secondary import the speculations which these con- siderations engender. It is good for a man to penetrate as far as he may into the established order of the universe, for its secret is his secret, its process is his process. Curious thoughts spring from brooding over these doctrines of the conservation of force A CHEMICAL PROLOGUE. 677 and matter. If in imagination we go back to that early time when our little planet was thrown off from its parent sun, we see, in the nebulous stuff from which it has precipitated, the materials of our own bodies. We are conscious of having had part in that wonderful birth, of having been present at the creation of the earth. It is true that we were very absent-minded at the time, but nevertheless our interest in that little ball of glowing vapor sent whirling off into space was even then a very personal one, for it was the aerial ship that carried our own destinies. If, then, the smallest atom that to-day forms a part of the delicate organ- ism which we hold to be the tool of an indwelling spirit, has ex- isted from all time, and is pledged to all eternity, it is difficult for the student of nature to conceive that the intellect which has given worth and dignity to this otherwise inanimate mass of matter should not be equally enduring. He is led to believe in an immortality of spirit which has known no beginning and will know no end. He is brought to what may be called the doctrine of the conservation of soul. It has been a dream of poets and philosophers that there is in all the universe but one true element, and that the so-called ele- ments— what we know as gold and silver, copper and iron, hydro- gen and oxygen — are but modifications of this one primordial unit. The chemists of the nineteenth century are turning poets and dreaming this dream over again. What would have been scorned but a few years ago as alchemists' madness is now orthodox science. It is hard to believe that such a heavy, infusible metal as platinum has anything in common with a light, combustible gas like hydrogen ; but, when we come to think about it, it is still harder to believe that the two are unrelated. When it is found that such dissimilar substances as charcoal, graphite, and diamond are chemically identical, it is quite possible to believe that all the elements are the products of a chemical evolution that has per- haps started with the element " helium," which the spectroscope discloses in the atmosphere of the sun. Thus the belief in the essential unity of the universe grows apace, and the cosmic drama gains in wonder as it gains in simplicity. What Goethe has called " the open secret of the universe " stares every man in the face. As one follows the wonderful story of its mode of be- coming, and traces the far-reaching harmonies and relations, he is moved to exclaim with the devout Kepler, " O God, I think over again thy thoughts after thee ! " These considerations by the way, have for their sole purpose the indication of what I feel to be the rational mode of approach to the study of chemistry. It is a science so competent to become a means of keen intellectual pleasure and a stimulus to the most profound thinking, that its neglect by all but special students 678 THE POPULAR SCIENCE MONTHLY. seems to me the neglect of a source of inspiration that one can ill afford to slight. Pursued in the spirit that I have tried to in- dicate, as a natural extension of the experimental knowledge of childhood, and through the medium of a few substances thoroughly studied, I venture to recommend it quite as highly as a means of culture, as an end valuable in itself. It would be an easy task to extend such considerations indefinitely ; but I want rather to open the right door into chemistry, than to decorate its vestibule. " It is a foolish thing," says the author of the Book of Maccabees, " to make a long prologue and to be short in the- story itself." ♦♦♦ THE PHYSIOGNOMY OF THE MOUTH. By TH. PIDEKIT. THE muscles of the mouth have a triple function. They serve- in the articulation of sounds, and assist the activity of the taste and the hearing. Our present study is limited to the move- ments of the buccal muscles, which have to do with the taste. Taste is the earliest developed of all our senses, and abides with us from the first to the last hour of life. No other sense controls man so early or with so much power ; none remains so long faith- ful to him. The lips may be regarded as a flat, circular muscle placed in front of the buccal cavity, cleft horizontally in the middle, with a moist, ruddy mucous membrane covering the edges of the open- ing thus formed. Not regarding now the muscles of the lower jaw, the mouth is closed by the contraction of the orbicular mus- cle of the lips, and opened by antagonistic muscles which are fixed on its outer edge. The mouth is, then, destined to undergo very great variations of form ; and, by virtue of this variety of its movements, it enjoys at least as much importance as the eyes in whatever concerns the mimetic expression of the countenance. When any object perceptible to the taste is placed upon the tongue at rest, the sensation of the contact is vague and im- perfect. It is only when the upper face of the tongue is pressed against the osseous vault of the palate that a complete impression of the object can be made upon the nerves of taste, the extremi- ties of which abut upon the caliciform papillae of this surface. Hence, when in mastication we inopportunely encounter anything of disagreeable taste, we at once separate our jaws to get the tongue as far as possible from the palate or to prevent any further rub- bing of the upper face of the tongue and repetition of the bad taste. The movement of the jaws is accompanied by a corre- sponding movement of the mouth. The upper lip is removed THE PHYSIOGNOMY OF THE MOUTH 679 from the lower lip as the palate is removed from the tongue by the levator muscles of the lip and of the wings of the nose draw- ing it up. Each of these two muscles rises near the inner corner of the eye, and ends in two points — one of which is attached to the wing of the nose, and the other to the middle lateral half of the upper lip. When these muscles come into play, the expression of the face is modified in a striking manner. The red edge of the upper lip is drawn up in the middle of its upper half, and this part of the lip is turned over, so as to give the line of its profile a broken appearance. The wings of the nose are raised, and the naso-lateral grooves, which, beginning at these wings, continue in an oblique direction to the commissure of the lips, appear near their beginning strongly pronounced and unusually straight. A still further effect of the movement is an even folding of the skin of the back of the nose (Fig. 1). The expression thus depicted, appearing primarily with bitter tastes, is also associated with other disagreeable feelings, which have become characterized by the term bitter. While in ordinary disagreeable representations and disposi- tions the skin of the forehead alone is wrinkled vertically, the bitter trait of the mouth also appears in such as are very disagree- able (Fig. 2). The significance and importance of this expression Fig. 1.— Bitter Expression. Fig. 2.— Bitter Expression, with Vertical Wrinkles on the Forehead. vary essentially according to the nature of the look. If it is dull, the face bears the impress of bitter suffering, and it is a sign that the person is suffering from bitter feelings and trials ; but if it is firm and energetic, the face then wears the marks of lively reac- tion and violent irritation. When the eyes are directed upward in ecstasy, the vertical wrinkles are of course absent, and then, while the upper lip is contracting bitterly, the face expresses a painful concentration. Such is the expression which painters have sought or should have sought to represent in the penitent 680 THE POPULAR SCIENCE MONTHLY. Magdalen. If, instead of vertical wrinkles, horizontal furrows appear on the forehead while the mouth is wearing the bitter trait, we recognize that the man is occupied with painful recollections. The physiognomy is most violently changed when the expres- sion of fear is manifested simultaneously with the bitter trait, or when the vertical and horizontal wrinkles both appear on the forehead at once. In this way the countenance receives the ex- pression of violent terror. Leonardo da Vinci describes this ex- pression in very striking terms when he says : " Paint wounded and bruised persons with pale faces and elevated eyebrows ; the whole, including the flesh above, covered with wrinkles, the out- side of the nostrils with a few wrinkles ending near the eye. The wrinkled nostrils should raise themselves and the upper lip with them, so as to expose the upper teeth, and these, parting from the lower jaw, will indicate the cries of the wounded." Dar- win describes other symptoms of terror and fear as follows : " The heart beats quickly and violently, so that it palpitates or knocks against the ribs. . . . The skin becomes instantly pale, as during incipient faintness. This paleness of the surface, however, is probably in large part or exclusively due to the vaso-motor center being affected in such a manner as to cause the contraction of the small arteries of the skin. That the skin is much affected under the sense of great fear we see in the marvelous and inexplicable manner in which perspiration immediately exudes from it. This exudation is all the more remarkable as the surface is then cold, and hence the term a cold sweat, whereas the sudorific glands are properly excited into action when the surface is heated. The hairs also on the skin stand erect, and the superficial muscles shiver. In connection with the disturbed action of the heart, the breathing is hurried. . . . One of the best-marked symptoms is the trembling of all the muscles of the body. . . . From this cause, and from the dryness of the mouth, the voice becomes husky or indistinct, or may altogether fail. ' Obstupui steteruntque comse, et vox f aucibus haesit ' " (I was amazed, my hair stood up, and my voice stuck in my throat). This form of mouth occurs physiog- nomically among persons of a soured nature. The sweet trait is opposed to the expression of bitterness ; for while that seeks to avoid as much as possible a disagreeable sen- sation of taste, in it the muscles are set to play in such a manner as to gather up the gustatory impressions as completely as pos- sible. The mouth is closed and the cheeks are strongly pressed against the teeth, so as to concentrate and retain upon the tongue all the parts of the sapid object, which during mastication and degustation glide between the cheeks and the jaws. In this way the activity of the nerves of taste is greatly assisted. The cheeks are pressed against the teeth chiefly by the action of the same THE PHYSIOGNOMY OF THE MOUTH. 68 i Fig. 3.— Sweet Expression. muscles as are exercised in laughing, and for this reason the sweet trait bears a degree of resemblance with the trait of the smile ; but the simultaneous contraction of the orbicular muscle of the lips suppresses to a considerable extent the lateral effect of the laughing muscles. The most es- sential characteristic, however, of the sweet trait is the peculiar form as- sumed by the lips ; their orbicular muscle being drawn closely against the teeth, the red lips lose their nor- mal swell, so as to appear flattened and straight when viewed in profile (Fig. 3). The mouth is drawn up in this way under the influence of un- usually agreeable, sweet tastes, and also as a mimic expression of ex- tremely pleasant feelings in the repre- sentations and recollections to which the usages of language have given the epithet of sweet. The sweet mouth, combined with an enraptured look, gives the mimic expression of a pleasant reverie ; joined with a sly look, the expression of amorous coquetry ; with horizontal wrinkles it suggests occupation with pleasant thoughts or recollections. It frequently appears when the lips are prepared to give a real or feigned kiss. Inasmuch as the very agreeable feelings to which the term sweet is applied are of only exceptional occurrence, this trait is rarely developed physiognomically. It hardly ever exists among men, but is occasionally found among extremely affection- ate women. When it becomes constant upon the face, it pro- duces an impression akin to that of a too constant sweet taste, as if there were too much of it. If we observe the trait plainly impressed upon a person, we shall be likely to find him in con- versation making much use of the word sweet, and speaking of " sweet women," " sweet music," " sweet love," and even of " sweet grief." The central fibers of the orbicular muscle are capable of con- traction independently of the lateral fibers, and this movement gives the scrutinizing trait. When we are on the point of tasting a sapid substance, such as wine, we introduce it between the lips projected into the form of a muzzle ; we then carefully let the liquid flow slowly upon the upper surface of the tongue, in order that the impression of the taste may be prolonged as much as possible, and we may gain more time to appreciate it. The same expression may be observed on the faces of men who are exam- ining the value of an object, whether it be something perceptible to the senses, or abstract thoughts or associations. The art critic 68z THE POPULAR SCIENCE MONTHLY. looking at a picture, the doctor feeling the pulse of his patient, the judge weighing the testimony of a witness, the merchant deliberating concerning the acceptability of a commercial propo- sition— all are tempted involuntarily to project their lips, as if about to taste something sweet, and that the more readily as they fancy themselves better qualified to form a judgment. This trait furthermore betrays a kind of feeling of one's own value, a feel- ing of superiority ; for whoever considers himself authorized and fit to pass a definite judgment on men, things, or events at once feels that by virtue of his quality of judge he rises superior to Fig. 4.— Scrutinizing Expression. Fig. 5.— Scrutinizing Expression, with Vertical Wrinkles. Fig. 6. — Scrutinizing Expres- sion, with Horizontal Wrinkles. the object on which he is called to pronounce. For this reason the scrutinizing trait is also often the expression of arrogance and presumption (Fig. 4). If the scrutinizing trait is associated with vertical wrinkles, it indicates that, while the man is weigh- ing and studying the reasons for and against the judgment he is to pronounce, whatever may be his final decision, he is already in a bad humor (Fig. 5). With horizontal wrinkles, the scruti- nizing trait indicates that attention is fixed in the highest degree upon the matters that are under examination, and that they are considered very important or very delicate. A fine representa- tion of this expression is given in Hasenklever's picture, "La Degustation du Vin " (" The Wine-tasting," Fig. 7). This expres- sion is frequently found among men who think much of the pleasures of the table. Their imagination indulging in fancies of pleasures obtained or anticipated, their lips advance as if they were really tasting what they are imagining ; and thus the scru- tinizing trait becomes physiognomic. It is also developed in men who have a high idea of their own value, and feel called upon to judge concerning the value of other men. THE PHYSIOGNOMY OF THE MOUTH. 683 When we make any very violent bodily effort, as to pnt on a tight boot, or to open a tightly closed door, besides contracting the muscles of the arm, we stiffen the neck, clinch the teeth, and press the lips close upon one another. It is very evident that these muscles do not in any way contribute to the attainment of the end proposed ; but at the moment when the man is calling upon all his strength and energy to overcome a difficulty by means of a bodily effort, the intensity of his will is mani- fested not only in the muscles that serve to produce the de- sired effect, but also in all the muscular apparatus of the body. Every muscle con- tracts ; and, of course, the con- traction of the weaker muscles is neutralized by that of the smaller ones. These simulta- neous movements, without in- tention or object, appear more evidently in the facial mus- cles, and notably in the vig- orous muscles of mastication. In all violent or difficult move- ments we are accustomed, by the contraction of the muscles, to press the lower jaw against the upper, as if we were tearing or breaking some hard object. The fact that we have noticed in connection with the bitter trait — that the movement of the lower jaw is accompanied with a similar movement of the mouth — is likewise observed in the pinched trait. As in the former case we remove, as far as pos- sible, not only the upper maxillary from the lower maxillary, but also the upper lip from the lower ; so, in the latter, we press the lower maxillary against the upper, and the lower lip against the upper. In consequence of the contraction of the orbicular labial muscle and of the incisor muscles, the lips are closely shut and their red edges are turned within ; but at the same time the lower lip is energetically pressed against the upper, by the action of the two levators of the chin. These muscles start from the upper edge of the lower jaw, near the median incisives, directing their fibers downward and outward, and lose themselves in the skin of the chin. They lift the middle of the lower half of the orbicular labial muscle, and press the skin of the chin closely against the bone. In consequence of this movement, the middle of the lower lip seems to be raised, and simultaneously two wrinkles or inden- tations appear, which, beginning at the middle of the lower lip, Fig. 7— Head prom Hasenklever's "Wink- tasting," Scrutinizing Expression. 684 THE POPULAR SCIENCE MONTHLY. Fig. 8.— Pinched Expression. are directed tlience toward the sides, like the sides of an obtuse- angled triangle, in a straight line downward and outward. These two indentations are very characteristic of the pinched trait, and correspond with the lower border of the tense labial orbicular, drawn up in its middle (Fig. 8). This expression is, however, provoked not only by very intense corporeal but also by very intense intellectual ef- forts. The efforts, however, which we make in mental works — in scientific researches, for example — are rarely passionate enough in their nature to bring on a spasmodic pressure of the lips and teeth ; but this takes place when we dispose ourselves for an intellectual com- bat, when one appeals to all the force of his will to defend himself against strange influences and guard his own convic- tions. The mouth closed firmly, with the lower lip raised, gives the expression of tenacity, stubbornness, obstinacy, and perse- verance. A person having his teeth and lips closely shut and the skin of his forehead contracted at the same time into vertical wrinkles, shows that he is angry, and firmly disposed to contend about the matter that is on his mind (Fig. 9). If his lips are pinched and Fig. 9.— Pinched Expression, with Vertical Wrinkles. Fig. 10.— Pinched Expression, with Hori- zontal Wrinkles. his eyebrows lifted up, he is trying to maintain the impressions that have determined him to an obstinate persistence in his opin- ions and intentions (Fig. 10). In J. Schrader's picture, " Gregory VII in Exile at Salerno" (Fig. 11), the tenacity of the mouth, the anger expressed in the vertical wrinkles, and the tense attention in the horizontal ones, joined with a secretive look, give to the face of the character the expression of a dangerous man who is contemplating perfidy and vengeance. Another combination is THE PHYSIOGNOMY OF THE MOUTH. 685 that of the pinched trait and vertical wrinkles with the bitter ex- pression of the mouth (Fig. 12). It remains to describe the complicated muscular movements that accompany a violent rage. The jaws are strongly pressed upon one another, in expression of an energy ready for the com- Fio. 11.— Pinched Expression, with Furtive Look; Fig. 12.— Pinched Expression, with Horizontal and Vertical Wrinkles. Bitter, and Vertical Wrinkles. bat, of a provoking resolution ; the upper lip is elevated and also the wings of the nose (bitter trait) so high that it is impos- sible to pinch the lips ; and the teeth of the upper jaw are seen above the upward-drawn lower lip. The nostrils are swelled out wide, for the movements of respiration and the heart are precipi- tate in rage, and the air is inhaled and expired violently to meet an obstacle in the tightly closed teeth, so that the breathing, pref- erably done through the nose, is facili- tated by the inflation of the nostrils. The forehead presents horizontal wrin- kles as a sign of close attention, and vertical wrinkles in expression of anger. The eyes look brilliant and "flash with fire" under the effect of the mental excitement, roll wildly in their orbits, or cast a fixed and pierc- ing look (Fig. 13). The pinched trait becomes physi- ognomical most easily and frequently with persons whose daily occupations fig. ia— pinched expression, with -i />, /» n • i • Bitter. Eyes wide open.

It may be developed among blacksmiths as well as among embroiderers, among butchers or sculptors ; but we may be sure that persons with whom we find it 686 THE POPULAR SCIENCE MONTHLY. are accustomed to do work with zeal and conscientiously. This trait can not, however, be developed physiognomically as the re- sult of intellectual efforts and the expression of tenacity, except the corresponding states of the mind are repeated not only often "but with duration. We recognize in them the tenacem propositi virum (man tenacious of his purpose) of Horace, the persevering man ; and also, when the expression of the pinched air is engraved with a particular force, the opinionated, obstinate, headstrong, hardened man. The expression of contempt, or disdain, is manifested partly in the eyes and partly in the mouth. A person who wishes to show his contempt raises his head in order to cast his look downward npon the object of his scorn ; he thus expresses that he feels superior to the one who appears low to him — only he does not look straightforwardly at the object, but side wise, as if he did not judge it necessary to turn his head in order to fix his eyes upon him ; at the same time the eyelids droop as in sleepiness and as a sign of extreme indifference toward the real or imaginary cause. Still, a certain degree of idle and con- strained attention is recognizable in the stretched appearance of the frontal muscles ; the eyebrows are drawn up and horizontal wrinkles are formed on the skin of the forehead (Fig. 14). Thus, a feeble degree of contempt is expressed only in the eyes, but in the rising de- grees of a haughty disdain the expres- sion of the mouth becomes modified in a peculiar way. The bitter trait appears in the upper lip, as if the person were feeling a disagreeable, nauseating taste, and simultaneously the lower lip is pushed forward and upward, as if in the desire to remove an insignificant object from the neigh- borhood of the lips. The sign that the object is regarded as very insignificant is derived from the fact that in elongating the lower lip we are accustomed to blow a little puff of air, as if that were enough to blow away so light an object. Hence the mimic ex- pression of contempt is a complicated one, and is related partly to imaginary objects and partly to imaginary sensorial impressions. As in the pinched trait, the lower lip is likewise drawn up in the trait of contempt, and in both cases by means of the two leva- tor muscles of the chin. The expression of stubbornness, how- ever, is essentially distinguished from that of contempt by the lips being drawn inward, while in contempt the lower lip is pushed forward. This is due to a combined action of the levator muscles and of the triangular muscles of the chin ; while the Fig. 14.— Expression op Contempt. THE PHYSIOGNOMY OF THE MOUTH. 687 Fig. 15.— Contemptuous Expres- sion in the Mouth. former push the lower lip upward and the corners of the mouth are depressed, the red edge of the lower lip is turned outward. Under the influence of the levator muscles of the chin, wrinkles characteristic of the lower lip are formed in the expression of contempt as well as in that of stubborn- ness ; but in the latter the wrinkles start from the middle of the lower lip and are directed in a straight line toward the base and outward, like the sides of an obtuse - angled triangle, while in the former they form, by tension toward the base of the triangulars of the chin, a curved line, the convexity of which is upward (Fig. 15). In both expressions the chin is flat, because its skin, under the influence of the levator muscles, is drawn upward and tightly stretched. If vertical wrinkles appear along with the expression of con- tempt, and the arched eyebrows and horizontal wrinkles are wanting, we judge that the person is under the influence of both anger and contempt (Fig. 16). The ex- pressions of contempt and bitter- ness may be combined, as signs of a corresponding complexity of feel- ings. The expression of contempt occurs physiognomically with pre- tentious, arrogant men, who are ac- customed to measure the conditions and opinions of others by the scale of their own imagined excellence, and who are hard to satisfy. This trait is manifested in the eye by highly arched brows, horizontal wrinkles, and depressed lids. In the mouth, we perceive that the middle of the lower lip seems pressed up, and that under its red border, which is slightly thrown out, an arched wrinkle is devel- oped, the convexity of which is turned upward. — Translated for the Popular Science Monthly from the Revue Scientifique.

Hirn deals with the question of the existence of an ether and its possible tenuity. Among the curious conclusions that he reaches is one that the density of a medium capable by its re- sistance of causing a secular acceleration of half a second in the mean velocity of the moon, would correspond with a kilogramme of matter uniformly distributed throughout a space of about three hundred and ninety thousand square miles. This is a density one million times rarer than that of the air reduced to one millionth of its normal density in Mr. Crookes's apparatus. 688 THE POPULAR SCIENCE MONTHLY. THE MEANING OF PICTURED SPHERES. By J. C. HOUZEAU. WHEN we take up a treatise on astronomy and come to the description of the constellations, we meet an amazing sys- tem of nomenclature. The celestial sphere is represented as cov- ered with fictitious figures of all sorts of personages and objects, to which the stars are referred. There are heroes, like Hercules and Perseus ; women, like Andromeda, Cassiopeia, and the Virgin ; a giant, Orion ; simple workingmen, such as a charioteer and a herdsman; a considerable number of animals, including two bears, a lion, a bull, a serpent, a crab, and a scorpion ; monsters, like the dragon and the Capricorn ; and various inanimate objects, from a crown and a harp to a river. No other science offers so singular a system of nomenclature, so far outside of scientific conceptions. In botany, zoology, and topography, objects have distinctive names. We are universally accustomed to apply to the things we speak of designations that belong to them ; but a system by itself, a figurative nomenclature, is applied to the groups of stars. This is a unique exception in the sciences. It is furthermore remarkable in this exception that it has held with all peoples who have made or begun a description of the sky. While the work may have been executed in isolation and in ignorance of the way followed by other nations, and the figures employed may be distinct, original, and inspired by the charac- ter of the people, the system of figuration has been the same. There must evidently exist a cause of a general nature which has directed the thought of man in this always identical direc- tion. There must be some feature in the aspect of the constella- tions different from those of other collections of natural objects and conditions which provoke a distinct work of the intelligence. This feature and these conditions we are concerned to find. It would have been no more strange to apply a figurative nomen- clature to topographical groups than to the stars. Persons who first arrive in previously uninhabited countries are obliged to give names to the landmarks of the region which they will occupy ; they have to distinguish the rivers and their affluents, the mount- ains and rocks. A chain of mountains might, perhaps, be more justly compared to a dragon than the file of stars that bears that name. The first mountain of the range might be the head of the monster, the second the neck, and the last the tail, while the lesser chains might be called the flippers or feet. This possibility is not to be rejected, for traces of a similar application are to be found in Formosa. The Chinese have, according to Ritter, put THE MEANING OF PICTURED SPHERES. 689 upon some of the Ta-Shan Mountains, which compose the nucleus of that island, the forms of men and figures of gods. But this is an isolated case. When we pass to uranography, the figurative system be- comes generally applied. It is well understood that the Greeks borrowed from the Chaldeans the general idea if not the details of their astronomy ; and we accept their pictured sphere. Other peoples of antiquity likewise had their figured spheres, formed on the same principle — only the stars were differently grouped by each people according to its fancy, and the symbols chosen were different. Nothing better proves the independence of these con- structions than this, but nothing also is more suited to exhibit what there is remarkable in this community of systems. The Egyptians had a pictured sphere in very ancient times. Signs of it may be seen in the tomb of Seti I, at Biban-el-Moluk, and considerable developments of it in the calendar sculptured on the ceiling of the tomb of Ramses IV, at Medinet Abou. There are on this monument, which is of the thirteenth century B. c, a series of constellations designated by imaginary figures. Among them are a river, an arrow, and a lion which differs from that of our classical sphere. There are a hippopotamus and a lute-bearer ; with a great asterism extending over nearly a quarter of the circumference of the sky, called the god Nacht, or the Con- queror, carrying a set of arms and ascending a stepping-stone. Another personage, Mena, is surrounded by servants. Egypt, therefore, in its uranography most distinctly followed the sys- tem of a pictured nomenclature. The Aryans of India did the same thing in another independ- ent manner. We find, among other things on their sphere, which was completed in the ninth century before the Christian era, a stork, two swine, a large tree with a dog in it, an Ethiopian with a giant's features, and a woman covered with a cloak. The Chinese adopted the system of small groups, and consequently consider- ably multiplied the number of denominations, so that their sphere bears more than three hundred names — names of person- ages and objects — forming in fact a figurative system. Here are the celestial pivot, precious stones, a bushel-measure, a woman embroidering, the sovereigns of the sky, and a number of the dignitaries of the Celestial Empire. The Arabs, previous to the time of Mohammed, also had a figured nomenclature, with a camel, a jackal, a sheep, an ostrich, and a dog ; among inanimate objects, a tent, a crib, a pot, a plate, a cubit, and a well-bucket. The Great Bear was a coffin, followed by the three stars in the tail as three mourners. While the groups were independent and the figures unlike, the system of figuration still prevailed. These peoples all had complete uranographies, covering every vol. xxxvi. — 44 69o THE POPULAR SCIENCE MONTHLY. part of the sphere that they could perceive above their horizon. Others, of a less advanced civilization, only named the more con- spicuous groups of stars. They merely made a start. Yet the problem presented itself everywhere under the same aspect, for the solution was much of the same kind. Thus, the Scandinavians had a dog, a chariot, a cross, and a spindle in the sky. The Eskimos put seal-hunters there. The Makah Indians of the strait of San Juan de Fuca, living on the sea-coast, chose figures of fishes and cetaceans. The Aztecs and Mayas saw animals there, including a scorpion, which does not correspond with our constellation Scor- pio. The Peruvians designated a jaguar, a cross-bearer, and a sheep suckling her lamb. The Puelches of Patagonia set ostrich- feathers in the Magellanic clouds. The Oceanian peoples applied figures to the constellations that impressed them. These facts will lead the reader to ask if the resemblance pre- sented by the configurations of some of the stars with familiar objects has not provoked comparisons of which the pictured sphere is a result. Thus, the constellation Gemini is composed of two lines of stars, each beginning with one of the first magni- tude. There is a striking duality in this, which has seemed to suggest the same representative idea in many quarters. But the Accadians, who gave us the constellation of the Twins, did not figure it as we do, nor as the Tahitians do. Instead of arranging the brothers side by side, they opposed them foot to foot. The small number of similitudes that we meet in the spheres of peoples distant from one another have an important signifi- cance. The Pleiades were nearly everywhere the first group that was remarked and named. The agglomeration of stars in it was of a nature to provoke the same kind of impressions. Yet differ- ent peoples attached different figures to it. The ancient Egyptians were struck by the idea of number, and, running into a prodigious exaggeration, called it by a name that signified thousands. In India they saw a hen and chickens in the group. This name spread thence to western Asia and then to Europe, and is still common. The similitudes were different in the New World. The Eskimos called the group the " bound together " ; in a great part of North America the thought is of a dance — with the Iroquois, of men and women; with the Chokitapias, or Blackfeet, a sacred dance around the sacred seed. We may pertinently recollect that in classic antiquity Hyginus said that the Pleiades were so dis- posed as to seem to be dancing around. The second stellar object that impressed primitive peoples is the milky way, which naturally suggests the idea of a road and a river. It is called the celestial river in China. To the ancient poets it was the stream of milk which Alcmene spilled when nurs- ing Hercules. To the philosophers it was the highway of souls, THE MEANING OF PICTURED SPHERES. 691 and had two gates, at the two places where it intersects the zodiac. The souls entered the world by the gate of the Twins (which cor- responds with the sign Cancer), and left it to return to the gods by the gate of Sagittarius (sign of Capricorn). It is a little re- markable that some of the American nations also called the milky way the highway of souls ; * but it does not appear so singular upon reflection. The milky way certainly resembles a road in its shape. Let us now recollect that a large number of people con- sign the souls of their ancestors to the sky ; hence the idea might easily have occurred frequently. There has also been a fortuitous and unconscious agreement among nations to give the name of the Bear to the most brilliant constellation in the neighborhood of the north pole. The primitive Sanskrit name of this constella- tion, according to Prof. Max Muller, meant " chariot," and this was the original image, which survives among some of our people to the present. But as the same word, rihsha, also designates a bear, there has sometimes been confusion, and the image of a bear was placed by the Greeks on the classic sphere. A bear was also represented by the principal North American Indian nations in the quadrilateral of this constellation. Only, these nations, who were familiar with the bear, did not include in the same constella- tion the three stars of what we call the tail, because the bear has only a very short tail, and this inclusion would have made it monstrous ; so they fancied them three hunters pursuing the bear. Now, is there anything extraordinary in the coincidence of like similitudes in the Old and New Worlds ? "We do not think there is. The bear is a polar animal. The constellation is large, and demands a large symbol. Facts prove this, for the constellation was a reindeer with the Eskimos, an elk with the Indians of Puget Sound, and an elephant with the Hindoos. The fortuitous coin- cidence of names in two different centers does not, therefore, seem hard to explain. It only implies that there is a resemblance with the adopted image in the aspect of the constellation. We should also consider that, within the limits of a certain compass of ideas, the number of objects to which it is possible to recur is restricted, and two peoples may be led by chance to select the same symbol for the same group of stars. This is visibly the case with the constellation Cancer, which is represented in Japan by another crustacean, the many-fingered limulus. I shall not insist upon the coincidence which La Condamine thought he had found, respecting the constellation Taurus, among some of the Indians of the Amazon. It is now understood that the term by which these Indians designated the Hyades did not mean a bull's jaw, but a tapir's. The examples of identity or of * J. F. Labitau, " Moeurs des sauvages Ameriquains," 4to, 1724, vol. i, p. 406. 692 THE POPULAR SCIENCE MONTHLY. seeming identity in the images are therefore reduced to a small number of comparisons. They are exceptional cases, in which the aspect of the asterism may have had something to do with the suggestion of similar images. Aside from this there is nothing in common : the figures set in the sky upon the constellations were peculiar to each people ; they were arbitrary creations, and that proves that the outlines formed by the stars did not directly suggest either personages or animals by which the imagination was struck. Apart from a few geometrical figures — a quadrilat- eral, a triangle, or a cross — the configurations of the stars pre- sented no relations with the objects selected to designate them. We are dealing, then, with a fanciful creation by each people, in which each one exhibited the peculiar tendencies of its imagina- tion and genius. This circumstance renders the nomenclature in question still more remarkable, since there is nothing or hardly anything in the aspect of the celestial tableau to provoke the construction of it. We return to the question with which we started : By what cause has a nomenclature so strange, unique in its kind, possessed, in a seemingly inevitable way, all the peoples who have looked into the sky ? For we might predict, from the generality of the method, that if some new people, having everything to begin again, should start to construct its system of knowledge, it would again make a pictured sphere for the stars. I will not pretend to answer a question of scientific archseology that has not been sounded, not even outlined, till now. If I suggest a solution, it is simply as an essay and hint, leaving it to professional students of folk-lore to enlighten us more fully. It sometimes seems to me that we might draw some indications of a comparison between the manner in which places in hitherto uninhabited countries are named and the nomenclature of the stars. When immigrants arrive in countries without inhabitants and unmapped, the first names given to the natural landmarks — the rivers, hills, clumps of trees, and rocks — are descriptive ones. These names often survive after the first arrivals have been dis- persed and replaced by other peoples ; and we know how ethnog- raphers find, in geographical appellations, the track, the limits, and the language of the ancient inhabitants of a country. In such primary nomenclature, they say, for instance, the blue water, the green mountain, the brown rock, the cedar wood, the steep cliff, etc. It was the natural course, which has been followed everywhere. Why has the human mind taken a wholly differ- ent course for the sky ? Was it not because the multiplicity of objects and their great resemblance had exhausted the series of descriptive terms ? Multiplicity often confuses the judgment ; for it is known that the view of the sky conveys the impression SKETCH OF A. F. J. PLATEAU. 693 of a larger number of stars than are really seen there. We instinctively halt before the seemingly impossible task of find- ing distinctive epithets for so many stars and asterisms; for, after a few such qualifications as blazing, sparkling, pale, trem- bling, etc. — perhaps there are twenty of them in all — we find that words fail. We suggest this explanation tentatively, without attaching particular importance to it. But we invite the serious attention of archaeologists, and psychologists as well, to the singular phenom- enon in mental evolution which the case of the pictured spheres discloses. It derives interest from its unique character as a nomenclature, and from its being reproduced, without exception, in all the centers of evolution. There is evidently something in the constant return of this process that comes from the very laws of our nature. — Translated for the Popular Science Monthly from del et Terre. ♦»» SKETCH OF A. F. J. PLATEAU. By SOPHIE BLEDSOE HEREICK. ANTOINE FERDINAND JOSEPH PLATEAU was born in Brussels, October 14, 1801. He was brought up in the midst of artistic influences, his father having been a flower-painter of great talent. From his earliest childhood the boy exhibited not only remarkable ability, but clearly manifested the bent of his mind. When scarcely more than a baby he showed the greatest delight in some physical experiments which were made in his presence. In the days when Plateau was a child, very little attention was paid to natural bent by parents in the selection of a life-work for their children. The idea of the hereditary transmission of occu- pation dominated all others. The boy, with no taste for art, was devoted at an early age by his father to the study of painting. At fourteen years of age he became an orphan, and with his two sisters was left to the care of his uncle — M. Thirion, an advocate. Soon after this his health, which was never strong, showed signs of failure ; and his uncle sent the children to a little village near Waterloo. It was upon the eve of the battle, and the villagers took refuge in the depths of the forest of Soignes, where for two days and nights they remained in the open air, sleeping at night before a great fire, and living upon potatoes which were baked in the cinders. The boy seemed scarcely conscious of the violent detonations which shook the ground beneath them, he was so absorbed in his favorite pastime of catching butterflies. The panic over, the vil- 69+ THE POPULAR SCIENCE MONTHLY. lagers went back to their homes, and Joseph and his sisters re- mained some time in the little village of Ohain. As soon as his health was restored he returned to his art studies. Here he made such excellent progress that one evening Prince Frederick, the son of the king, who was visiting the estab- lishment, was attracted by the boy's work. When he found that Joseph was an orphan, he said, " Well, from this moment I take you under my protection." Later, when M. Thirion wished to remind the prince of his promise, he was deterred by the boy's unwillingness to make any claim upon him. Painting occupied Joseph by day, but in the evening and in his leisure moments his beloved physics employed all his time. With the aid of some young friends he organized soirees, the en- tertainment being experiments of his own devising, made with apparatus constructed by himself. At sixteen years of age he entered the Athenaeum at Brussels. He omitted certain studies, but in all that he undertook he dis- tinguished himself by his enthusiastic progress. His masters became at once interested in their brilliant pupil. The friendship of Quetelet, which became stronger as time went on, proved of the greatest benefit to him in later life. His school-life over, the subject of a profession presented itself for reconsideration. His uncle pressed upon the boy the study of law, as the noblest of all professions, and Joseph consented. In choosing art there had been no great sacrifice ; he had been too young at that time to know his own mind ; but he felt a strong antipathy to the law. This dislike did not prevent honest and conscientious work in the pursuit of his legal studies ; but the physical sciences held for him their old fascination, and he made the rather singular com- promise of studying both law and physics, and doing himself credit in both alike. His faithful work had its reward at last : his uncle, seeing his determination, and at the same time his will- ingness to be guided, withdrew his opposition, and the young stu- dent gave himself up wholly to scientific pursuits. The care of his younger sister now fell upon Plateau, and, pressed by the necessity to provide for them both, he accepted the professorship of elementary mathematics in the Athenaeum at Liege. This was in 1827. In 1829 he received the degree of Doctor in Physical Sciences and Mathematics, and from that time he gave himself to original research. During this year he devoted much time to experimenting upon various points in regard to vision, to the persistence of impres- sions upon the retina, subjective color, etc. On one occasion, to determine some point, he looked at the sun for twenty-five sec- onds with the naked eye. For many days after this hazardous SKETCH OF A. F. J. PLATEAU. 695 experiment his eyes were strongly affected, bnt he did not sus- pect that he had done them a permanent injury. This experi- ment undoubtedly laid the foundations of that disease which twelve years later brought on total blindness. After being forced to resign his work, in 1830, he again re- sumed it at Brussels. In 1835 Quetelet urged Plateau to apply for the professorship of experimental science in the University of Ghent. The young savant refused at first to offer himself as candidate for a position in the first institution in his native land, pleading youth and inexperience; but later his scruples were overcome, and he received the appointment to the chair. As soon as he began his work in Ghent, he found the collec- tions of the university very poor and meager. He gave himself at once to the work of remedying this deficiency. In order to inform himself, he visited and examined minutely the most cele- brated collections in England, France, and Germany. He ad- dressed the Government and the inspector of the university, and pleaded his case so well that in the end — though it was only after long and wearisome labor — he succeeded in securing one of the finest physical cabinets in existence to the University of Ghent. In 1840 Plateau married Mile. Clavareau, daughter of a director of tax-collections. She was always a devoted wife and true help- mate to him. Outliving him, she was able to comfort, sustain, and help him when darkness settled over his life. In 1841 his son Felix, now Professor of Zoology and Comparative Anatomy in the University of Ghent, was born. During the same year the disease which ended in total blindness made itself felt. For two years he submitted to the most painful treatment in hopes of saving his eye-sight. The trouble which had attacked the right eye extended to the left. During these long months neither his terrible affliction nor his excruciating suffering ever drew a word of complaint from his lips. The courage which showed itself in this heroic endurance was far from being merely passive. Nothing daunted by what, in a lesser man, would have ended his life's work, Plateau never lost courage. The future must have looked very dark even to his courageous spirit, but he gave no token of failure. Happily, all material anxieties were removed by the action of his countrymen. He was appointed "professeur ordinaire," and a little later a royal order, countersigned by M. Rogier, assured him of the en- joyment of the entire salary and emoluments of his position. A noble recognition of the man and of his services — a recognition fully justified by forty years of fruitful work, and by a series of discoveries "which have made Belgian science illustrious through- out the entire world." 696 THE POPULAR SCIENCE MONTHLY. As soon as Plateau found himself fairly out of the physicians' hands, with restored health, he resumed his experiments with ardor. He was most happy in finding co-laborers who gave him the most efficient and willing help. " Thanks to their generous co-operation," said he, " the career of scientific work remains open to me. I can, in spite of the infirmity with which I have been visited, put in order the materials which I have amassed, and even undertake new researches/' When this experimental work began again, Plateau showed at once that the clouding of his physical sight had only served to clarify his mental vision. At first he could not give up his inde- pendence, and for some time he wrote between metallic slips ; his assistants soon learned to decipher the writing. Later, however, he gave up this habit, and contented himself with writing to dic- tation. His temper was usually calm and equable ; he never uttered a complaint on account of the many deprivations which his blind- ness imposed. He was bright and amusing in his conversation, and yet he was, as all thinkers are, in the main, sober. His memory, which was naturally a good one, had become phenomenal by cultivation. It was only necessary to hear an ordinary poem read once or twice for him to be able to repeat it accurately. This gift was one of his greatest compensations for the loss of sight, and of incalculable benefit in his experiments made by the hands of others. His method, given by his son-in- law and biographer, G. van der Mensbrugghe, is as follows : In a day devoted to experiment, speaking of the latter years of the physicist's life, he says : " The old man's face is animated ; he an- nounces with admirable precision all the precautions to be taken that the apparatus should work. According to his often expressed desire, the assistant acquaints him successively with his opera- tions, even to the smallest point. No manoeuvre is left to his personal valuation. The apparatus is at last ready to be set in motion. The master, who imagines and regulates all the disposi- tions, makes still other suggestions ; he assures himself by differ- ent means that all is ready in accordance with his will. At last the assistant is asked to operate — the experiment succeeds ! What a satisfaction, what a relief for the noble worker who has con- ceived it ! For greater assurance he causes it to be repeated, with various modifications suggested by the descriptions of the ob- served effects. If all passes as he has foreseen, he at once asks his secretary to write to his dictation all the details of the experi- ment. No point is forgotten, for the provisional wording ought to represent, as exactly as possible, all that had been verified. But if the observation did not meet his expectations, in spite of the precautions he had deemed necessary, the physicist promised SKETCH OF A. F. J. PLATEAU. 697 himself to think it over again. He would then devote a part of the night to revolving the question again and again under all its aspects, to seek the cause of the failure and the means of future success." His enthusiasm would sometimes put his assistants' patience to a rather severe test, and he would cry out, " Oh, if I could only see ! " but as soon as success crowned his efforts, the indefatigable experimenter loved to express his gratitude. He cross-questioned Nature with more severity because he could only receive her an- swers by the voice of an interpreter. The thousand obstacles that presented themselves because of his infirmity only suggested a thousand precautions in order to surmount them. His inner vision was so preternaturally clear that he often corrected the observations of his assistants, and taught their eyes to see aright. The love of scientific accuracy is not so much a mental as a moral quality. Plateau was possessed of a supreme love for truth, which not only made him accurate in his investigations and in the records of his experiments, but it made him careful not to judge others without a full knowledge of the facts. Always ready to ascribe scientific discovery to the right persons, he spared no pains to know who was the true discoverer. The instructions which he gave to his pupils bore his own pe- culiar stamp. He used simple language and almost a conversa- tional tone. His phrases were short, incisive, and clear, a fitting medium for the expressions of a mind so unclouded, so direct, and so concentrated. His talents as an experimenter were even more marked than as a speaker — more marked, because it is a far more uncommon gift. He was an old-fashioned believer. The more deeply he " pene- trated into the secrets of Nature, the more he inclined toward the mysteries of the supernatural order," says his biographer. The picture of his home-life— his delight in and tenderness for his children in his early manhood, and the same gentle benevo- lence shown toward his grandchildren in his old age — is very beautiful. As a scientist he is held in very high esteem by the greatest of his contemporaries. Honors were showered upon him by the great scientific societies of Europe. Such men as Arago and Fara- day were glad to do him honor. His earlier work was confined to the subject of the persistence of luminous impressions upon the eye and the determination of several simultaneous impressions under various conditions of mo- tion. Many of the scientific toys of to-day are the outcome of facts and laws established by him, though he is not often accred- ited with these earlier discoveries. With the study of persistence of visual impression is so closely associated subjective color that 698 THE POPULAR SCIENCE MONTHLY. this soon came under consideration, both accidental color which follows an impression and that caused by juxtaposition. He sim- plified the subject greatly by making this division of the subject, the first class including all appearances which succeed the con- templation of a bright-colored object, the second those which ac- company such contemplation. The phenomena had been observed before, but Plateau was the first who reduced them to law. Some valuable experiments and formulated theories on the subject of irradiation were begun, but was interrupted by his on- coming blindness. Before this time, Plateau's attention had been fixed by the spherical form which a drop of oil assumed when introduced into an alcoholic liquid having the same specific gravity as the oil. From this small beginning he developed a most wonderful series of experiments and laws under the title " Memoirs upon the Phe- nomena which a Free Mass of Liquid presents when removed from the Action of Gravity." Eleven papers upon this general subject appeared between the years 1843 and 1868 in the memoirs of the Academy of Brussels. These included his experiments upon films and the formulation of the laws which govern their union — one of Plateau's most valuable contributions to physical science. He also made some very interesting investigations upon liquid jets, with a number of shorter papers and notes upon vari- ous subjects. Most of these papers appeared in the memoirs or bulletins of the Academy of Brussels, a few in the French and German annals of science, " Comptes Rendu de l'Acade'mie des Sciences de Paris," and Poggendorff 's " Annalen." He died Sep- tember 15, 1883. It is impossible to read of Plateau's work, carried on for so many years in spite of frail health and total blindness, and not draw a parallel between Huber and himself — each of them a man who was the peer of any worker in his own field, though so cruelly handicapped. They are two of the purest, noblest, most pathetic, most heroic figures who adorn the annals of science. While believing it premature till some new groups of lines are further studied to express more than provisional suggestions as to the nature of certain nebula? he has been examining spectroscopically, Mr. Huggins supposes that they may represent an early stage in the evolutionary changes of the heavenly bodies. They consist probably of gas at a high temperature and very tenuous, where chemical dissociation exists, and the constituents of the mass are arranged in the order of vapor-density. But the stage of evolution which the nebula in Andromeda repre- sents is no longer a matter of hypothesis. Eecent photographs show a planetary system at a somewhat advanced stage of evolution. Already several planets have been thrown off, and the central gaseous mass has condensed to a moderate size as compared with the dimensions it must have possessed before any planets had been formed. CORRESP ONDENCE. 699 CORRESPONDENCE. A FALLACY OF THE SOCIALISTS. Editor Popular Science Monthly : DEAR SIR: Is not the laud question, viewed from an American standpoint, simply a disagreement about methods rather than ethical principles ; and are not the dis- tinctions sought to be established between absolute and relative political ethics more subtle than philosophical or accurate ? A great part of the land in the United States was in the beginning, and much of it is still, just in the condition demanded by Mr. Laidler and his confrh-cs — the absolute property of the Government. Almost the whole country was at first " held by the great corporate body — society," without any sus- picion of " violence, fraud, the prerogative of force, or the claims of superior cunning " in any way affecting the sources to which titles are traced. Government was free to do as it would with its possessions : either to sell, lease, or farm them in its own behalf. Government — that is, society — chose to sell or give away the public domain in fee-sim- ple, reserving the right of eminent domain. The moment land is reduced to private own- ership, it becomes subject to taxation, and must bear its share of the burdens of soci- ety. It contributes toward the maintenance of roads, schools, infirmaries, hospitals, and all the complicated machinery necessary to the well-being of the social fabric. If land, subject to private ownership, fails to pay its tax assessments, it is forthwith confiscated and reverts to the state, which finally sells it, without possibility of redemption, to some other person who will pay the taxes — that is, contribute to maintain society. Who decides what amount of burden land shall bear ? Not the private proprietor certainly, but society. No private owner can evade this implied contract — namely, to contribute as much to the support of society as society may deem necessary. Hence every citizen may be said to have an interest to the ex- tent of his political or social influence in all the lands of the commonwealth. And the tenure of every landholder depends on his ability to meet the burdens laid upon his land by non-owners, since these everywhere constitute a majority. Strictly speaking, therefore, there is no such thing as private ownership of land in the sense in which the expression is used in the discussion. The owner may sell, lease, or bequeath his hold- ing ; but the usufruct of society, which exists prior to all other claims, can not be avoided. Mr. Laidler's assertion, therefore, quoting from Mr. Spencer, that if men may make the soil private property, " then the Duke of Sutherland may justifiably banish High- landers to make room for sheep-walks," is \ fallacious. This false assumption invali- dates equally all of the ten sections which compose his argument. As land tenures ex- ist in the United States, the landless men, instead of becoming subject to " expulsion from the earth altogether," would be far more likely to bring about the confiscation of all of the duke's vast possessions by the legiti- mate exercise of their constitutional powers of direct and indirect taxation. It may be urged that the existing tenure of land in the United States does not repre- sent the status of private ownership in older and densely populated countries, and still less so that possible condition of the earth and mankind contemplated by the expound- er of absolute political ethics. The obvious reply is, that neither condition is essential to the continuation of private ownership. Let the Socialists direct their complaints against hereditary privileges and the abuses of private ownership, and not against that coincident form of land tenure which, when properly ad- justed, is best adapted to realize their views. If all lands in Great Britain could be suddenly transferred to the crown, is there any way in which society could better man- age or dispose of them than the United States has adopted ? No better way, cer- tainly, has yet been indicated. Government here — notably the State of Ohio in the man- agement of her school lands — tried for many years all known methods of leasing these lands, and all ended in conspicuous failure. Her public men universally denounced the system of leases, after experimenting with it in all possible ways, until an act of Congress authorized the school lands to be sold. If society, after actual experience, has con- demned and abandoned the methods advo- cated by the Socialists, and adopted the ex- isting form of private ownership as the best which statesmanship has to offer, what rea- son is there to suppose that the resumption of public ownership, if it could be accom- plished, would lead to better results in the future ? Under the present form of private holdings, land is made to yield the largest possible returns, and to contribute of its products the largest possible contingent for the benefit of the landless. Can any theory of government or system of philosophy be true which is inconsistent with obvious facts ? James L. Taylor. "Wheelebsbueg, Ohio, December 30, 1S89. A DEFENSE OF "ADVANCED" WOMEN. Editor Popular Science Monthly : I have read the article by Grant Allen in the October number of " The Popular Sci- ence Monthly," and I wish to say that if I knew even one woman of " advanced " ideas JOO THE POPULAR SCIENCE MONTHLY. holding the opinions he attributes to them I should value the article in that proportion ; but as I do not know a single one — and I have lived a good deal among women of "advanced " ideas — I can not help thinking the article worse than uncalled for. As far as I know anything about it, those who shirk the duties of maternity have ideas very far from advanced : they are the poorer kind of society women, many of whom would be horrified at being suspected of intelli- gence or independence. The charge used to be that women be- came spinsters because they could not get husbands, and that was considered sufficient- ly opprobrious. Now Mr. Allen charges them with unwillingness to take husbands ; and yet states in the same breath that the marriageable men go off beyond reach when they " ought to be making love," etc. Here is an arraignment indeed ! Why not devote an article — any number of arti- cles— exclusively to these marriageable men ? The great body of noble women who have thrown themselves into the struggle for equal freedom are behind no one in desire for true womanliness and femininity. Already we are well on the way to the emancipation that Mr. Allen pleads for, the sound bodies and minds that are to come from the free and entire development of girls and boys, and freedom from Mrs. Grundy ; but all the progress made is due to these " women-ques- tion agitators." If there exists this deplorable indiffer- ence to marriage on the part of women, is it not the consequence of the very state of things that these leaders are striving to abol- ish— and also, perhaps, of the sacrifices that this strife entails, and of some of the char- acteristics that are inevitably developed by it, and that no one knows or deprecates more than these valiant workers themselves ? All reforms have their attendant evils ; but it is the state of things that called for the reform that is to blame for them — or the " nature of things." We need patience, hands off, fair play without privilege, and that each should think most of his own duty. A. A. M. Boston, December 15, 1889. PUBLIC SCHOOLS AND CKIME. Editor Popular Science Monthly : As I have more than seven hundred pu- pils under my charge, and that, too, in a State not backward in common-school education, I venture to protest against being lodged in a criminal-making class. Like Mr. Reece, I would ask, " Of what utility are facts and experiences unless their teachings are heeded and their meaning properly interpreted ? " With Mr. Atkinson, I say, " All statistics, un- less qualified by sound judgment, are mere rubbish." Mr. Reece mentions the fact of the in- crease of criminals since the period of mod- ' ern civilization and science commenced, but I he does not mention that the methods of tracking criminals have wonderfully in- creased, so that we may have a larger ratio of criminals caught than in days before the swift post, the telegraph, the police system, the photograph, and the extradition treaty. Surely he should give the public school the praise of supplying some of the means of catching the criminal after it has made him ! I will say nothing about the increased accu- racy of the statistics of 1880 over those of the earlier period. While discussing criminality in New York State, he states that the common schools furnish eighty -three per cent of the inmates of Auburn and Sing Sing, while a little over nine per cent is credited to the illiterate population. Out of 2,616 convicts, 1,801 are credited to the common school and 238 to the illiterates. I can not see that even his own arrangement of the figures is against us. Surely nine per cent is a much larger ratio, when compared with the number of illiter- ates in New York, than eighty-three per cent would be if compared with the number of the common-school graduates. It seems to me that he should have taken as bases for his example in social arithmetic the num- ber of illiterates and the number of common- school graduates. I have not the statistics of illiteracy in New York at hand, but I be- lieve the figures will show fully three times as large a ratio of criminals to be credited to them as to the common school. Mr. Reece cites various savage tribes as being examples to us in morals. He fails to see that temptations are increased a thou- sand-fold for the civilized man. There could not be many thefts where all property is held in common, when the property owned is so paltry as not to be worth the carrying away. 1 do not contend that the public school is doing all it is able, but it is doing as well as the church and the family are doing in their spheres toward elevating the moral tone of the community. Writers like Mr. Reece seem inclined to find fault with us because we can not do the work of the fam- ily and the church. We are doing a good share of it, but, under the triple burden, we may sometimes fail to send out all good citi- zens. Very truly, Charles S. Davis. Lynn, Mass., January 15, 1890. A NOVEL WATER-COOLER. Editor Popular Science Monthly : My article in the January (1890) number of the " Monthly " brought me an inquiry from Quincy, Illinois, as to where the writer could get an olla (pronounced o-ya), and what it would cost. Here in southern California they are plenty, and the regular retail price is twenty cents a gallon. What the trans- portation would be I do not know. Since my article was written I have heard EDITOR'S TABLE. 701 of another way of keeping water cool, which I have never seen exemplified. A grain- sack, such as is used by the Eastern farm- ers, is painted and filled with water, and hung up in a cool place where the breeze strikes it. The olla, too, must be kept in a breezy place. Wind will dry clothes or a field, and so it will evaporate the water oozing through an olla, or barrel, or, I suppose, the painted grain-bag. The evaporation is what does the cooling, according to a well-known principle of physics. Henry J. Philpott. Pasadena, Cal., January 13, 1890. THE LTJCAYAN INDIANS. Editor Popular Science Monthly : Sir: With reference to Prof. Brooks's paper, " The Lucayan Indians," in the No- vember number of the " Monthly," I have ex- amined one or two caves during the past summer, and have been intending to make a more thorough search during the winter ; so, if any of your readers should feel inclined to adopt the professor's suggestion, I shall be glad to co-operate. Although no doubt the aborigines of the Bahamas had intercourse with Hayti and Cuba, the possession by them of stone imple- ments does not, as Prof. Brooks supposes, prove it ; for, although the islands consist solely of coral rock, yet stone, identical in appearance with that of which the stone im- plements are usually made, is constantly be- ing washed up on the northern shore of New Providence, and probably elsewhere ; so that the Lucayan implement-makers would have had plenty of material in the archipelago. Also, it must not be too hastily con- cluded that all remains found in caves in the Bahamas are Lucayan. Negro skulls have been found more than once, and in one cave I found, consolidated into breccia, a number of bones which a local anatomist pro- nounced to be those of " some large verte- brate animal." They presented an appear- ance of great antiquity, and, had we not known that there were no large animals in these islands at the time of their discovery, they would certainly have been referred to pre-European days ; whereas, they were probably the remains of an ox which had been killed and eaten by runaway slaves, for the surface of the rock showed traces of fire. Yours faithfully, A. B. Ellis. Nassau, N. P., November 28, 1889. EDITOR'S TABLE. HOW TO MAKE KNOWLEDGE REAL. THERE was an interesting discussion a month or two ago at a meeting of the Chicago Institute of Education. A paper had been read by one of the members of the Institute, Mr. Fernando Sanford, on "The Disciplinary Value of Scientific Study," which is stated to have been a strong and well-constructed plea for the study of science by original observation rather than by the ordinary text-book methods. Many of our read- ers would expect that unqualified as- sent would have been given to the ar- gument of the paper ; but it happened that an eminent educationist was pres- ent in the person of Superintendent Howland, of the Chicago public schools, who dissented entirely from Mr. San- ford's thesis. He thought all this talk about observation of facts and handling of objects was great nonsense ; why not let children learn out of books that things were so and so, and commit the facts to memory ? What was the use of all the accumulated knowledge and in- telligence of the ages, if children were to begin at the beginning and make over again for themselves discoveries that were made centuries ago ? Life was too short, he held, for this kind of thing. Let the pupil start with the knowledge of his own day as gathered and gar- nered in books, and not bother to find out things for himself. Moreover, man and his institutions are more worth studying than all the world besides. It would be a misfortune, he thought, if the advice given in the paper were fol- lowed in the schools. We take the report of this speech as we find it in the columns of our contemporary " Intelligence " of Chi- cago, and we judge by the remarks that followed that the meaning we attach to it is precisely that which it conveyed to those who were present. These views, expressed by a man holding a most im- JOZ THE POPULAR SCIENCE MONTHLY. portant official position, and eminent as an educational leader, are so strikingly opposed to the general verdict of scien- tific educators as to challenge exami- nation. The question is, how shall sci- ence be taught? Only experience can answer. If there is any fact that experience has overwhelmingly illus- trated and established, it is that mere book-teaching of science is void and of no effect — nay, that it is worse : that it has an actively injurious effect on the mind, which it deadens with meaningless jargon and befogs with ill-comprehend- ed notions. The highest scientific au- thorities have proclaimed this; and a committee of the American Association for the Advancement of Science put on record three or four years ago their de- liberate opinion that the book science taught in the schools of this country was valueless for any purpose of intel- lectual discipline. Superintendent How- land must have observed in the course of his wide experience how hollow and often how fantastically absurd are the ideas children acquire of things of which they are told, but which they have never seen or handled. Every one who has been a close observer of his own contem- poraries must be aware of many a man and woman who, for want of early and practical familiarity with this or that class of physical facts, labors under a confirmed disability in dealing with all facts of that particular order. How is a knowledge of or interest in flowers and plants (for example) to be acquired, if not by personal handling and ob- servation of the objects themselves? And are there not many persons who, for want of this practical training, go through life with little knowledge of flowers beyond the fact that they are of various colors and odors, and of plants that they are for the most part green and require soil and sunlight for their growth ? Many a man will give abun- dant testimony showing how hard he has striven in mature years to gain a little knowledge from books of this or that branch of science, and what terribly up- hill and, in the main, ineffectual work it has been, just on account of defect in his powers of observation, and in that memory for the forms and qualities of physical things which due exercise of the observing habit in early life devel- ops. Take any man on the ground that has become familiar to him by actual observation, and he is at his best. Talk to the sportsman about guns and game, and you are amazed at the profusion and minuteness of his knowledge. Talk to the naturalist, and he is inexhaustible in his descriptions and explanations of the objects of his craft. Talk to the geologist, and you will find that the strata and their fossil contents are the true re- alities amid which he lives. But talk to any man about that which he has only learned from books, and, though his speech may be copious, it will lack a certain living quality that comes only from conversance with realities. Even in such a domain as history, which some may say can not be learned except from books, there is a marked difference be- tween the man whose memory is sim- ply laden with names and dates, and the man who has become, in a sense, practi- cally acquainted with the memorials of past ages — who has studied their monu- ments, their arts, their coins, their char- ters, their institutions, and who has vivified the whole by a knowledge of similar things belonging to the present time. It is safe to say tbat no man will ever understand history from the mere perusal of a narrative; he must, in a man- ner, make himself a contemporary of the times he is reading about ; and then he may know the past a little as an intelli- gent man of affairs knows the present. We had a splendid example here in this city not many weeks ago of what book-teaching of science amounts to. The "Evening Post " gave a selection of over fifty answers given by young women of the average age of seventeen, all pupils of our public schools, most of them having gone through the highest EDITOR'S TABLE. 703 grade, to five very simple questions forming an examination paper set for candidates for admission to a free sten- ographic class at the Cooper Institute. These damsels were asked, among other things, to state how many motions the earth has, and how much time each oc- cupies ; also what causes the change of seasons. These things had been fully explained to them, as was supposed, at school ; and all, or nearly all, had in point of fact retained some shreds of the phraseology in which the expla- nations had been conveyed. Here are some examples of the answers to the question as to the motions of the earth : " One motion. One year. The mo- tion of sun round the earth." " Two motions. Night, Day, twelve hours for each." "Four motions, it revolves on its axis around once a year, and the four motions cause the seasons spring, sum- mer, fall, and winter." " The revolution of the earth on its axis, and the inclination of 23J per cent of its poles to the plane of its orbit." " Two motions, day and night. The sun causes the earth to move around its axis every twenty-four hours." " Two, Regular and Circular, twelve hours for each." " If the earth would not be round, the sun and moon could not go round the earth. Sun takes twenty-four hours. Moon takes twenty -four hours. Stars at night." "We can not afford more space to this rubbish. Suffice it to say that our con- temporary prints the answers given to the several questions by fifty-six of the candidates, and that they all display the most deplorable ignorance and confu- sion. The problems of how science shall be taught in the public schools, or indeed whether it shall be brought into them at all, depend for their solution upon having the right kind of teachers. They need to realize the utter ignorance of the child- mind as it comes for instruction to the public school, and to understand how to build up in that mind a fabric of real and coherent knowledge. Let us turn children out of the public schools igno- rant, if need be, of many things that are taught to them now ; but let this idea at least be rooted in their minds, that this world is made up of real things; and this further idea, that words are worse than useless unless they can be applied in the most definite manner to well-understood objects of sense or of thought. What a blessing it would be if we could inspire the rising generation with a real horror of vague and meaningless language ! It would mean nothing less than an in- tellectual revolution in the world — or at least in our considerable pbrtion of it. THE RECOGNITION' OF TRUTH. If there should arise a class of men who were able to distinguish, promptly and invariably, genuine things from imi- tations, facts from falsehoods, and truth from error, they would have an almost inconceivable advantage in the struggle of life. The tricks of impostors would never deceive them ; the bubbles of vis- ionaries would never delude them ; they would never be misled by the sophistries of shallow theorists ; never be enslaved by baseless superstitions. Such wisdom is so unlike what the world has ever known that the idea savors of Utopia or the millennium, and to express it seems almost childish. Yet it is a fact that some progress toward this ideal has been made — some increase of the power of recognizing truth has been gained. A class of men has arisen whose pursuit of health is not hampered by the delusion that disease is a punishment for lapses from religion, who do not waste their money on schemes for getting more power out of a machine than is put into it, who do not accept every state- ment that is put to them with rhetorical vehemence and defective evidence. This superior discernment — far from perfect, but the best that man has ever had — 7°+ THE POPULAR SCIENCE MONTHLY. is the possession of those who have adopted the scientific habit of thought. A writer in the "Lancet" remarks that a supersensitiveness with regard to truth is the essential characteristic of a scientific frame of mind. Every sugges- tion that is offered in explanation of phenomena which are imperfectly un- derstood is received with cautious re- serve. This characteristic is liable to be mistaken for uncertainty or for preju- dice ; but in reality it is solely the out- ward sign of a just appreciation of the numerous sources of fallacy, which so often tend to render -the most brilliant speculations worthless, when examined rigidly and coldly by the ideal standard of truth. When gauging the probability of the truth of any suggested explana- tion, it is held to be scientifically un- sound to welcome it merely because some one of undoubted honesty of pur- pose has expressed his entire belief in it. There is always the possibility of mental bias to be reckoned with, as well as the possibility of unconscious delu- sion. No single sense is to be implicitly trusted. A preconceived idea may lead to the recognition of one property, while others of greater importance are over- looked. Pushed to its logical conclu- sion, this ideal standard of truth de- mands more proof than can ever be obtained, and for working purposes it is found convenient to employ what may be called provisional truths, which we accept on account of the facts that appear to support them being vastly more numerous than those that appear to oppose them, or because they have been set forth by careful, conscientious observers, after thorough consideration and elimination of all probable sources of error. Imperfect education fosters delusion ; indeed, delusions are most rife with the ambitious condition which often comes from " a little learning," when the whole is liable to be rashly assumed from the part ; when a false appearance of truth may bo mistaken for explanation ; when the result of an erroneous observation, unchecked by scientific training, may be hastily considered to amount to demon- stration. Education can have no more important aim than to equip pupils with the best known method for the recogni- tion of truth. Every day of their fives they will have to decide as to the truth or falsity of some statement ; and what is to prevent their going astray, if they have not been practiced in searching out all modifying circumstances of a problem, if they have not been accustomed to finding the balance of evidence, and taught the great lesson that judgment is not to be given rashly, but must be sus- pended when sufficient data to warrant a decision are not obtainable ? The old studies of our schools do nothing toward training the young in examining evi- dence and forming judgments. The study of science, however, when rightly conducted, mainly consists of the pro- cess of investigation, the very instru- ment which pupils must be able to use handily in after life to save themselves from becoming the victims of impostors and swindlers. Aside from the material advantages involved, the habit of mak- ing truth the goal of his exertions in- spires in the young learner a respect and fondness for truth for its own sake which can not fail to have an elevating influence on his character. Science should have, therefore, an important place in every school programme ; it should be introduced in the lowest grades, in order to give the child's un- folding faculties the proper bent; and it should be continued throughout the school course in order to save the half- formed habit of intelligent inquiry from being lost by an interruption of its ex- ercise. Our children could well afford to grow up in ignorance of the height of Mount Ohuquibaraba and the length of the Brahmapootra ; they might dis- pense with a smattering of French, or do without the Latin declensions and conjugations, if the time thus saved en- abled them to gain some facility in sift- LITERARY NOTICES. 705 ing truth from falsehood. An encour- aging improvement in our educational ideas has been shown of late, and it seems as if the time could not be far distant when all who have any voice in the training of the young will see clear- ly what knowledge and what acquire- ments are of most worth. LITERARY NOTICES. Individualism, a System of Politics. By Wordsworth Donisthoupe, Barrister-at- Law, author of " Principles of Plutolo- gy," etc. London and New York : Mac- millan & Co. Pp. 393. Price, $4. This is a work which we feel justified, after a careful perusal, in commending to the study of our readers. The questions which it discusses are of the first impor- tance, and Mr. Donisthorpe gives one the impression of a man thoroughly familiar with his own ground, and whose conclusions have not been formed at hap-hazard or with- out deep and earnest reflection. The main idea of the book is that individualism proper- ly understood furnishes the key to a true political system. The last thing Mr. Donis- thorpe would wish to do would be to relax the bonds of society. His aim, on the con- trary, is to strengthen and perfect society, in the first place, by a scientific separation of the domain of the state and that of pri- vate activity ; and, secondly, by carrying to its fullest legitimate development the prin- ciple of individual liberty. He has not, per- haps, developed his thesis in the most co- herent manner possible ; we think the work might be rearranged and perhaps some- what compressed, with advantage to the main argument ; but meantime we are glad to recognize in it a powerful and timely plea for principles of government with which " The Popular Science Monthly " has always been distinctly in sympathy. Mr. Donis- thorpe writes as a lawyer ; and the influence of his juristic studies is visible on every page. At times his argument gains in force through the dispassionate practicality of the legal mind ; and at times it assumes a character somewhat too forensic for the best general effect. In Chapter I we have a discussion of the growth and evolution of the state. There is vol. xxxvi. — 45 nothing here distinctly novel. As regards the origin of political government the author accepts the ideas of Mr. Spencer, and refers also with approval to " the learned and fas- cinating works of the late Sir Henry Maine." He develops well, however, the idea that the tendency of modern times has been toward the forming of larger and larger political aggregates ; and that in the pres- ent day the facilities for communication and transport which science has made available have increased more wonderfully than ever the possibilities of state growth. Apparent- ly Mr. Donisthorpe's ideal is one center of law — so far as law is an absolute necessity — and the widest possible individual liberty throughout the whole community. He is not a friend to what is called " local op- tion " ; he considers that it means little else than local tyranny, and perhaps he is right. He does not believe in cutting up a country into larger and smaller geographical squares, and making the conditions of life for each man depend on the particular square in which he chances to live. He holds that the same (legal) conditions of life should be available for all members of the community, and that these should be of the simplest character possible. " Imperial law," he says, "must henceforth be based on individual and local liberty." Chapter II deals with "The Structure of the State." The author announces him- self a thorough-going democrat, and ventures to lay down the principles to which a true democratic government must conform. We must refer to the book itself, however, for his definition and defense of democracy, in- cluding the principle, unreservedly accepted, of universal suffrage. One remark here is worth quoting : " Majorities for their own sakes would do well not to bring minorities to bay. The result may be either painful or humiliating — painful, as when the minority (in heads, in riches, and in organization) withstood the tyranny of the Stuarts ; hu- miliating, as when England bowed down before the determined Boers of the Trans- vaal. It is not wise to threaten what you do. not mean to perform. Minorities mean action ; majorities as a rule do not." In Chapter III, on " The Functions of the State," we have, in the first place, a resume of the functions commonly assigned 706 THE POPULAR SCIENCE MONTHLY. to modern governments ; and, secondly, a criticism of the tendency, just at present in the ascendant, of looking to legislation for the cure of all ills and the securing of all benefits. "The spirit of the individualist movement," the author tells us, " is one of resistance to any overstepping by the legis- lature of its normal boundaries. It is the embodiment of the absolute principle of civil liberty, or the greatest possible liberty of each compatible with the equal liberty of all." We need hardly observe that this is sound Spencerian doctrine. Later on in the volume the author has a good deal to say in criticism of Mr. Spencer's " Man vs. the State " ; but this does not prevent his recog- nizing Mr. Spencer, on the first page of his preface, as the man "who has contributed more to the scientific study of society than any other thinker — not even excepting Au- guste Comte or John Austin " ; and as the one to whom the merit belongs " of formu- lating this (the individualistic) theory of government, and thus of laying the rough foundation on which a sound art of politics may be based." Mr. Donisthorpe laments the fact that in England to-day "the Con- servative party have thrown in their lot with state socialism," and are" now playing with the Liberals a game of grab for the votes of those whom a Socialistic programme attracts. He shows reasons, however, for holding that the present tendency is rather an eddy in the general current, than a main movement likely to be continued in the fu- ture— a reaction toward unintelligent politi- cal methods due to the recent inclusion (he is speaking of England) of lower layers of the population in the electorate. We pass over Chapters IV and V, en- titled " What is Property ? " and " What is Capital ? " which do not seem to us to have a very direct bearing on the main purpose of the bock ; while the style in which they are written is somewhat tiresomely dispu- tatious. The chapters on " The Labor Question" and "The Capitalization of La- bor," which immediately follow, are, on the other hand, full of interest. In the first of these the author describes with great force the present economic condition of the la- boring classes. He accepts without reserve the Ricardian doctrine of the tendency of wages to a minimum, maintaining that it has been so irresistibly proved a priori that to discuss it in the light of any partial facts or observations is the merest waste of time. He pours unmeasured ridicule on the new- fangled doctrine of " the standai'd of com- fort" by which some political economists try to make the Ricardian law appear less cruel in its operation. " Wagedom," says Mr. Donisthorpe, is only a shade better than serfdom, and is virtually a kind of serfdom. The remedy for it, however, does not lie in socialism, which would only aggravate all the ills of society, but in the substitution for the wage system of what Mr. Donisthorpe calls " the capitalization of labor." His idea is briefly this: The wage-earner at present takes, when he can get it, a certain average wage from his em- ployer, the amount of which does not de- pend upon the profitableness or otherwise to his employer of the business carried on. In other words, the employer insures the laborer a certain wage independently of the fortunes of his business. Now, nobody insures an- other without charging something for it ; and the capitalist class recoup themselves for insuring a certain average wage to their employes by putting that average wage some- what, perhaps considerably, below what their average profits would justify. By the capi- talization of labor Mr. Donisthorpe means treating labor as capital (which he con- tends it is), and establishing a partner- ship between it and capital — a true partner- ship, in which gains and losses would be shared. Mr. Donisthorpe shows how a be- ginning might be made by taking the aver- age wages in one or more lines of business for a certain number of years, and fixing the proportion which these had borne to average profits during the same period. The laborers might then approach the capitalists and say: These are the wages you have been able to pay us on the principle of in- suring us a fixed compensation whether your business prospered or not. Now, we wish to throw our labor as so much capital into your business, on the understanding that, if your profits are greater than the average profits of the period we have been considering, you will pay us in proportion, and that, if they are less, you will pay us in proportion also. We must refer those of our readers who wish to see how much can be urged on behalf LITERARY NOTICES. 707 of the plan proposed, to Mr. Donisthorpe's book, merely observing that, in point of prac- tical suggestiveness, we consider the two chapters last mentioned worth a score of such books as " Looking Backward." We do not say that every difficulty has been fully met ; but we do say that Mr. Donisthorpe has pro- pounded a scheme which is not necessarily Utopian, and which seems to contain great promise of good. Surely, on the face of it, it is evident that society must some day dis- cover some better principle than that ac- cording to which the laborer of to-day pro- fessedly gives the least amount of work for the largest amount obtainable in wages, and the capitalist the smallest amount in wages for the largest amount obtainable of work. Such a principle means war, means waste, means wide-spread social demoralization ; and it must, if society is to endure, be suc- ceeded at no distant day by some true prin- ciple of accommodation and harmony, in virtue of which it shall become the interest of the laboring classes to promote the crea- tion of wealth by faithful and intelligent work, and the interest of the capitalist class to extend the fullest measure of justice to those whose labor fructifies their capital. The closing chapter of the book contains a most effective criticism of socialism in re- ply to a Mr. J. L. Joynes, who, if we remem- ber rightly, was a co-laborer with Mr. Henry George in England. It is satisfactory, in these days of crude theories and doleful vaticinations, to meet with a book written in as sober and withal as cheerful and hopeful a spirit as this of Mr. Donisthorpe's. We wish very much that the more helpful por- tions of it could be presented to the public in briefer and more popular form ; but, as it is, we trust that the book, as a whole, will be read and pondered by all who are inter- ested in social problems. Introduction to the Study of Philosophy. By William T. Harris. Comprising Passages from his Writings, selected and arranged, with Commentary and Il- lustration, by Marietta Kies. New York : D. Appleton & Co. Pp. 287. Price, $1.50. This compilation has been made in order to adapt for class use the teachings con- tained in the miscellaneous philosophical works and articles of Dr. Harris. Many of the passages have been taken from the " Journal of Speculative Philosophy," others from the editor's prefaces to volumes in the " International Education Series," from Dr. Harris's lectures at the Concord School of Philosophy, and from his articles in various educational journals. The illustrations sup- plied by Miss Kies are such as she has used with her classes of girls at Mount Holyoke Seminary. The opening chapters deal with " Methods of Study," the " Presuppositions of Experience," and the " Philosophy of Nature." The rest of the volume deals with man as a self-active individual, taking up in successive sections sense-perception, repre- sentation, reflection, the syllogism, the abso- lute idea or the reason, the emotions, and the will. The concluding chapter discusses the immortality of man. " Philosophy as presented by Dr. Harris," says Miss Kies in her preface, " gives to the student an inter- pretation and explanation of the phases of existence which render even the ordinary affairs of life in accordance with reason ; and, for the higher or spiritual phases of life, his interpretations have the power of a great illumination." Problems of the Future, and Essays. By S. Laino. London : Chapman & Hall. Pp.409. Price, 3s. 6c?. It is characteristic of man to take pleas- ure in measuring his strength against obsta- cles. In the youth of the individual or the race, he delights in athletic contests ; in the prime of life, he enjoys the struggle to obtain subsistence and comforts for his family, and the rewards of social eminence ; and at a more advanced period the study and more or less perfect solution of intellectual problems afford him satisfaction. The world, or at any rate the Anglo-Saxon race, may be said to have reached its maturity, and intellectual problems are exciting our interest and en- gaging our powers as never before. There have been a few philosophers in every age since the beginning of history, but scientific, social, and religious questions are now occu- pying the minds of many who do not claim to be philosophers. " There is a large and, I believe, rapidly increasing class," says Mr. Laing in his introduction, "who have al- ready acquired some elementary ideas about 708 THE POPULAR SCIENCE MONTHLY. science, and who desire to know more. Curi- osity and culture are in effect convertible terms : the wish to know is the first condi- tion of knowing. To many who are in this stage of culture, but who have neither the time nor faculty for following up closely the ever-widening circle of advanced thought, it may be interesting to get some general and popular idea of some of the unsolved prob- lems which have been raised by modern sci- ence, and are occupying the thoughts of the men who lead its van." To meet the want defined in this passage is the object of the present volume. The questions which the author discusses in his earlier chapters re- late to the past history of the earth and other cosmic bodies. These are, How long has the sun been giving out heat enough to sustain life on the earth ? What is the uni- verse made of ? What has been the climate of the earth in geologic times ? When was the Glacial period, and how long did it last ? From these topics he passes to the consider- ation of the antiquity of man and the method of his origin. A chapter is devoted to " Ani- mal Magnetism and Spiritualism " ; several religious questions are then taken up ; and, finally, certain economic problems are con- sidered. The religious questions are, whether agnosticism is reconcilable with Christianity ; how great a historical element there is in the Gospels ; and whether the skepticism of the present day justifies pessimism. " The Creeds of Great Poets " are also passed in review. First of the political and economic essays is an analysis of the reasons for the tension which keeps Europe constantly armed ; the others deal with the financial problems of England, and the increase of population with reference to the food-supply of the world. In the case of each problem which he raises, Mr. Laing makes evident what solution he deems most probable. His discussions show a thorough knowledge of and sympathy with the scientific enlightenment of the times ; and, in regard to those questions which man must answer in the future, he is generally confident that science will be able to give a beneficent solution. The only exception is in regard to the food problem, where he can see relief only from a diminished birth- rate or an increased death-rate, and the idea of discovering new ways of producing edible products is not mentioned. Timber and some of its Diseases. By H. Marshall Ward. London and New York : Macmillan & Co. Pp. 295. Price, $1.15. This work originated in a series of short articles in " Nature," and forms one of the Messrs. Macmillan's "Nature Series." It is intended as a popular scientific rather than an exhaustive and technical account of its subject. The opening chapters deal with the general character and structure and the properties and varieties of timbers ; also with the classification of timbers based on these properties. An extended review of the the- ories about the ascent of water in tall trees is given, the conclusion of the author being that of the imbibition theory of Sachs and the osmosis-gas-pressure theory of Hartig and Godlewski and others, the latter is the more probable. While he admits that the rhyth- mical character of the respiration of proto- plasm, on which the osmosis-pressure theory depends, is not proved, he maintains that re- cent researches are in favor of Godlewski's views as to the behavior of the protoplasm. The next three chapters deal with the dry- rot and other diseases of timber caused by various fungi, figures of which are given. The structure of the bark of trees, and the process of healing wounds by occlusion, are then described, with illustrations. Returning to diseases, the author describes " canker," or the larch disease, leaf diseases, and pine blister. The final chapter deals with the " damping off " of seedling trees. Institutes of Economics. By E. B. An- drews, D. D., LL. D., President of Brown University. Boston: Silver, Burdett & Co. Pp. 227. Price, $1.30. The most conspicuous feature of this book is the thoroughness with which its con- tents has been analyzed, classified, and an- notated. It is introduced by a chapter de- fining the field of economics and stating the nature of the chief schools of econo- mists. The body of the work is divided into six parts, devoted respectively to production, exchange, money and credit, distribution, consumption, and " practical topics involving economic theory," which last includes chap- ters on coin and paper currency in the United States, taxation, and poverty. It is an ele- mentary text-book, intended for classes in colleges and, with perhaps the omission of LITERARY NOTICES. 709 the most difficult sections, for high-school and academy classes. Its point of view is historical, though it maintains the existence of general economic laws, absolutely and universally valid. Its sundering of eco- nomics from ethics, jurisprudence, and soci- ology in general is less arbitrary than in most treatises. It makes wealth, not ex- change, the central conception of the science, and recognizes immaterial wealth as well as material. On the difficult topic of value, the fresh analyses of Bohm-Bawerk and Men- ger are heeded and in part followed. The leading ideas are distinguished by heavy type, and each section is accompanied by a list of references bearing upon its subject- matter, and by copious notes. The volume lacks an index. Eclectic Physical Geography. By Rus- sell Hinman. Cincinnati : Van Antwerp, Bragg & Co. Pp. 382. 12mo. Since physical geography includes parts of nearly all branches of science, and its study precedes that of the sciences in many schools, an introductory chapter has been prefixed to this book, in which the chief properties of matter and of heat, light, magnetism, and electricity are set forth. The topics forming the body of the book are arranged in a logical order, putting first the relations of the earth to the other members of the solar system. After this difficult sub- ject has been disposed of, the atmosphere is considered, for the reasons that it forms the outer envelope of the earth, and that its action is the proximate cause of all de- tails in the relief of the land and of the more conspicuous phenomena of the sea. Next come descriptions of, first, the sea, and then the land. The subject of climate follows these, and the concluding chapters deal with life, from yeast up to man. The details concerning the various topics are put in small type. The text is illustrated by one hundred and fifty cuts and many maps. A Lenape-English Dictionary. Edited by Daniel G. Brinton, M. D., and Rev. Al- bert Seqaqkind Anthony. Philadelphia : The Historical Society of Pennsylvania. Pp. 236. Price, $3. This vocabulary is based upon an anony- mous manuscript in the archives of the Mo- ravian church at Bethlehem, Pa., supposed to have been compiled by the Rev. C. F. Dencke, and containing about three thou- sand seven hundred words. The manuscript was carefully examined by the Rev. A. S. Anthony, who is a born Lenape, after which he and Mr. Brinton together passed in review every word in the dictionary. No attempt has been made to increase the lexicography by the insertion of words or forms obtained from the Delaware language of to-day. The editors have confined their efforts to pre- senting this work as exclusively concerned with the dialect as employed by the Mora- vian missionaries ; and hence all additions to the vocabulary have been from their writings. A full index enables the equiva- lent of any English word to be found in the dictionary, if it is therein. The volume is printed on rough, heavy paper, with un- trimmed edges. It is the first of " The Penn'a Students' Series," a series of volumes to contain material of interest to the students of Pennsylvanian history. Copies may be procured from the Librarian of the Histori- cal Society, 1300 Locust Street, Philadelphia. The Industrial Progress of the Nation. By Edward Atkinson, LL. D., Ph. D. New York : G. P. Putnam's Sons. Pp. 395. Price, $2.50. Under the above title Mr. Atkinson has combined two series of magazine articles dealing with economic subjects, together with two or three addresses not before pub- lished. The statements and inferences pre- sented in this volume are based on the author's extended study of the national ac- counts and the statistics of international commerce. In the paper which stands first, the idea is presented that " while the power of mankind to consume the products of the earth is limited, the source from which man may draw satisfaction for his material wants is practically unlimited." A special part of the subject of production and consumption, namely, the food question in America and Europe, is treated in the next essay, and a host of facts and figures are given bearing on the existence of waste and want side by side. In the two articles on " The Relative Strength and Weakness of Nations," the strength of democracy, as shown in America, and the weakness of nations which are gov- erned by monarchs, are analyzed. Following these is a series of papers dealing with the distribution of the products of industry, and 710 THE POPULAR SCIENCE MONTHLY. as connected with this subject the author discusses in another essay the question " What shall be taxed ? " The general con- clusions to which this series of inquiries leads him are, that the working classes are obtain- ing a constantly increasing and the capital- ists a constantly diminishing share of an increasing product ; that the share which any person may secure depends upon his use of his own abilities ; and that all laws restricting the free use of time and talent are inconsistent with progress. In the latter portion of the volume are papers on " Slow- burning Construction " (illustrated) ; " The Missing Science " (in which an economical method and apparatus for cooking are de- scribed) ; " A Single Tax on Land " ; and "Religion and Life." The discussions in this volume are characterized by thorough- ness of study, and an earnest desire to spread enlightenment on these important subjects. A third hand-book of pronunciation has been published by William H. P. Phyfe, en- titled Seven Thousand Words often Mispro- nounced (Putnam, $1.25). It is intended to include all the English words and names and the foreign words liable to be mispronounced by an English-speaking person. The words are all arranged in one alphabetical list, the names only beginning with capitals. Pro- nunciation is indicated by respelling in full, and in some cases how the word is not sound- ed is also indicated, and other explanatory notes arc inserted. Where several important pronunciations of a word occur, the fact is indicated, Webster's pronunciation being gen- erally placed first. Prefixed to the list are a chapter on the sounds of the English lan- guage, suggestions on the use of the book, and a key of diacritical marks. The author enumerates forty-two sounds in English, al- though the American Philological Associa- tion recognizes only forty — the two addition- al ones being obtained by distinguishing the vowel in serge from that in urge, and the one in dog from that in odd. Two instances of carelessness are, that the author names as one :>f his authorities " Worcester's Unabridged Dictionary," meaning " Worcester's Quarto Dictionary," and the only pronunciation of Algonquin given in the Supplement to Web- ster is ignored. The volume is printed in clear type on fine paper. We have received of what might be styled calendar publications of the Smith- sonian Institution, Mr. G. H. Boehmer^s Re- port on Exchanges for the year ending June 30, 1887, and nine Accounts of Progress in as many branches of investigation in the year 1886. In the first of these publications, Mr. Boehmer, after relating the year's trans- actions in his office, reiterates the recom- mendation that has been made in previous reports, for the designation of a permanent agency abroad to give personal attention to the business of exchanges. His opinion that otherwise only temporary results can be obtained is confirmed by his own experi- ences.— In his Account of the Progress of North American Geology for 1886, Mr. Nel- son H. Darton has sought to include ab- stracts, without bias or partiality, of all im- portant publications distributed during the year. It is unfortunate, and hardly in keep- ing with the character of an institution like the Smithsonian — especially when three years are taken for the printing — that hur- *ried preparation is offered as a reason for imperfections, and limitations of space for omitting the bibliography, which is to be made a bulletin of the Geological Survey. Mr. C. G. Rockwood, Jr., arranges his Ac- count of Progress of Vulcanology and Seis- mology under the heads, as heretofore, of Vulcanology — including volcanic phenomena of 1886, volcanic phenomena of previous years, and causes of volcanic action ; Seis- mology— earthquakes of 1886, earthquake lists of 1885 ; catalogues of earthquakes of previous years, and study of earthquakes ; and Seismometry — instrumental records and instruments. A bibliography of eight pages is appended. — Mr. John Belknap Marcou furnishes to the series a Bibliography of North American Paleontology, giving the titles of works in the order of the authors' names, alphabetically, and descriptions or analyses of the contents of the more elabo- rate ones, in some instances of considerable fullness. — The Account of Geography and Exploration, by William Libbey, Jr., com- prises extremely brief accounts, by conti- nents, of the principal explorations of the year, their purposes and facts. In the Ac- count of Progress in Physics, Prof. George F. Barker gives lucid analyses of the principal papers presented, with results determined LITERARY NOTICES. 711 or suggested on the general subject and in mechanics, heat, light, and electricity. A necrology and bibliography supplement the text. — Prof. H. Carrington Bolton, in the Account of Progress in Chemistry, gives similarly clear notices of papers, discoveries, and experiments in chemistry, with necrolo- gy and bibliography. — The Progress of Min- eralogy is described by Edward S. Dana under the heads of " General Works " on the subject, " Crystallography and Physical Mineralogy," " Chemical Mineralogy," " New Mineral Occurrences in the United States and Elsewhere," and " New Minerals." The bibliography includes brief references to papers upon mineral species. — As character- istic of Progress in Zoology, Mr. Theodore Gill observes that more and more attention is being paid to histology and embryology, perhaps at an undue expense to sytematic zoology, and regrets the tendency as hurtful to the welfare of the science, but hopes that in due time it will be corrected. The sub- ject is reviewed in the order of zoological classification, and a necrology is supplied. — In the account of Progress of Anthropology, Prof. Otis T. Mason draws attention to com- prehensive summaries, courses of lectures, and descriptions of instrumentalities. The heads are, " Archaeology," " Biology," " Psy- chology," " Ethnology," " Comparative Phi- lology," and "Mythology and Folk Lore." Clear ideas of the principal papers are given in the abstracts. A bibliography is added. Mr. Otis T. Mason gives in the papers of the United States National Museum a valu- able contribution to anthropology in the shape of an illustrated paper on the Cradles of the American Aborigines. The author finds that in both Americas the majority of aboriginal children are confined in a sort of cradle from their birth till they are able to walk about. During this period the cradle serves many purpose's — as a mere nest for the helpless infant, as a bed so constructed and manipulated as to permit sleep in either a vertical or horizontal position, as a vehicle for carrying the child suspended on the moth- er's back or from the saddle-bow, as, indeed, a cradle to be hung on the limbs of trees to rock, as a playhouse and baby-jumper, and as a kind of training school whence the child emerges little by little till it leaves it altogether. These various uses are exhibited in the accounts which follow of the cradle systems of the different tribes. Methods of strapping the limbs and treating the head and their effects on the form, also enter into consideration. — Mr. Walter Rongji's pa- per On the Preservation of Museum Speci- mens from Insects and the Effects of Damp- ness considers the virtues and defects of various poisonous preparations, and supplies directions for accomplishing the objects im- plied in the title. — Ethno - Conchology : A Study of Primitive Money, by Robert E. C. Stearns, describes the many kinds of shells that have been applied by primitive people in all parts of the world to the purposes of a currency, the methods of preparing and using them, more particularly the wampum belts of our Eastern Indians, and the shell money of the Pacific coast. The text is illustrated by nine plates and many inserted cuts, and some dozen other papers are cited in the bibliography. — Dr. J. H. Porter's Notes on the Artificial Deformation of Chil- dren among Savages and Civilized Peoples is also published in connection with Prof. Ma- son's Cradles, to which it bears a close rela- tion, as it is in the cradles that the deforma- tions are started. The subject is considered by Dr. Porter from a broad philosophical point of view, without much reference to special methods of deformation. These are mentioned in a summary of " General Notes on Deformition," which is at the same time a bibliography. — Prof. Mason's The Human Beast of Burden is of a piece in value and interest with his paper on " Cradles." The author is set by the sight of an express train to reflecting on the long and tiresome experiences through which the human mind has passed upward to that climax of inven- tion. At the lower end of this line " we come at last to the primitive common carrier, the pack-man himself, and also the pack- woman, for men and women were the first beasts of burden." This person, with his load and his method of attaching and man- aging it, are considered under the aspects they present or have presented in different countries and ages ; and the whole is made plain by means of pertinent illustrations. Further contributions by Dr. R. W. Shufeldt to the study of the bone-structures of birds include Observations upon the Oste- ology of the Order Tubinares and Stegano- 712 THE POPULAR SCIENCE MONTHLY. podes, or albatrosses, fulmars, shearwaters, petrels, gannets, cormorants, pelicans, etc. ; similar Studies of the Sub-family Ardeinoe, of which the great blue heron, Ardea hero- dias, is selected as the type ; and, under the heading of Contributions to the Comparative Osteology of Arctic and Sub-arctic Water- Birds, a memoir on " The Auklets." The number of The American Journal of Psychology (E. C. Sanford, Worcester, Mass., $5 a year) which completes its second year contains three principal articles. The first of these is by Charles L. Edwards, on the "Folk-lore of the Bahama Negroes," and embodies many stories similar in character to those which have been recently obtained from the negroes of our Southern States. The collection is introduced by several pages of description of the islands and the peo- ple. The second paper is " On some Char- acteristics of Symbolic Logic," by Christine L. Franklin. The fourth and concluding paper of Dr. W. H. Burnham's series on " Memory, historically and experimentally considered," appears in this number. In this paper Dr. Burnham sketches the prog- ress of recent theories. He finds that the view that " the essence of memory is a functional disposition persisting in the brain is, perhaps, the one most widely held by con- temporary psychologists." He also glances at the recent experimental studies upon memory, and appends to his paper a bibliog- raphy of the most important literature of the subject. In The Chemistry of Narcotics, a pam- phlet by Prof. E. Haworth (the author, Os- kaloosa, Iowa, 25 cents), a brief account is given of the preparation and chemical char- acter of the common alcoholic beverages, chloral, the bromides, and the vegetable alkaloids. A table of percentages of alco- hol in foreign and domestic alcoholic bever- ages is appended. Tlie Cosmic Law of Thermal Repulsion (Wiley, 15 cents) is an attempt to account for the tails of comets. The author's view is, that the projected matter forming the tail has been separated from the body of the com- et by the radiant energy of the sun. He states the details of his hypothesis in the present essay, and quotes from many scien- tific authorities passages which directly or indirectly support it. The popular lectures and discussions given before the Brooklyn Ethical Associa- tion last winter have been published in book- form under the title Evolution (James H. West, Boston). The fifteen papers on vari- ous evolutionary topics which the volume comprises were noticed in these pages when published separately. A paper on Marine Shells and Fragments of Shells in the Till near Boston, by Prof. Warren Upham, has been published in the Proceedings of the Boston Society of Nat- ural History, Vol. XXIV. The fossils here described have been before regarded as evi- dence that the land in which they are found had been previously submerged beneath the sea. Instead of this, the observations of Prof. Upham go to show that the fossils were brought to their present positions from the bed of the sea on the north, by the ice- sheet. In the same volume is a paper on The Structure of Drumlins, also by Prof. Upham. Another recent paper by him, on Olaciation of Mountains in New England and New York, is published in " Appalachie," Vol. V, No. IV. In a bulletin on Natural Gas in Minne- sota, the geologist of that State, Prof. N. H. Winchell, reviews the geological facts and the results of experiments bearing on the question whether gas in any considerable quantity is likely to be found in Minnesota. His conclusions are, that the great forma- tions that furnish gas in the United States are almost wholly wanting in Minnesota ; that the gas which comes from shallow wells at Freeborn is confined'to the drift ; and that if gas is found in Minnesota in a lower forma- tion than it has been found in anywhere else, as has been predicted, it will be something new in geology. The publication of a treatise on the Pa- leontology of the Cretaceous Formations of Texas has been undertaken by Prof. Robert. T. Hill, of the University of Texas, at Aus- tin. It is to be published in installments, at twenty- five cents each. Part I, now issued, comprises descriptions of three specimens, with plates. The same author has also pub- lished Part I of a Check-List of the Inverte- brate Fossils from the Cretaceous Formation* of Texas, accompanied by Notes on their Geo- graphic and Geologic Distribution. In " The LITERARY NOTICES. 713 American Journal of Science " has appeared recently a paper by him on the Relation of the Uppermost Cretaceous Beds of the Eastern and Southern United States, and in "The American Geologist " another on The Fora- miniferal Origin of Certain Cretaceous Lime- stones and the Sequence of Sediments in North American Cretaceous. The little Hand-Book of Precious Stones, by M D. Rotlischild (Putnam, $1), gives a brief sketch of the properties of each min- eral used in jewelry. The specific descrip- tions are introduced by directions for recog- nizing and determining the characters by which the quality of precious stones is ascer- tained. A table of hardness and specific gravity is appended. Three memoirs on Meteoric Iron, by George F. Kunz, relate respectively to a mass weighing VS\ ounces, which was found on Linnville Mountain, N. C, about 1882 ; a mass of 25*61 pounds weight, which was found in Laramie County, Wyoming, in Jan- uary, 188V ; and the Johnson County (Ar- kansas) mass, which fell in 1886, and is note- worthy as having been the largest mass ever actually seen to fall. It weighed 107-2 pounds. Physical descriptions, chemical analyses, and photographic illustrations of the stones are given. Another paper by Mr. Kunz includes *' Mineralogical Notes " on " Phenacite from Maine," " Quartz Pseudomorphs after Spo- dumene," " A Remarkable Variety of Trans- parent Oligoclase," "Apatite from near Yon- kers, N. Y., " Cyanite from North Carolina," and an " Aragonite Pseudomorph." A valuable contribution to the study of the structure of the crinoids is given in a paper entitled Discovery of the Ventral Structure of Taxocrinus and Haplocrinus, and Consequent Modifications in the Classifi- cation of the Crinoidea, by Charles Wachs- muth, of Burlington, Iowa, and Frank Springer, of Las Vegas, N. M. The descrip- tions are supplemented by excellent plate illustrations. PUBLICATIONS RECEIVED. Aekerman, A. A., U. S. N. Notes on the Man- agement ot Boats in the Surf. Pp. 14.

The Fnturc of our Weather Service. — Everybody has been noticing that more and more of our official weather predictions turn out wrong, and in the hope of restoring their former efficiency several bills have been in- troduced into Congress within the last few years for transferring the Weather Service from the War Department to a civil bureau. The reasons for such a change, as stated in a pamphlet sent to us by Mr. H. H. Clayton, are that military regulations hamper the scientific work of the bureau, and cause civilians, who have joined the service from aptitude for science, to resign. The abler military men, also, seeing no hope of pro- motion in the Signal Corps, generally pre- fer the line. The natural result has been that, as General Greely reports, the service is full of incompetents, and the percentage of successful weather predictions has de- creased in the last five or six years from eighty-seven to seventy-six per cent. Dur- ing the same time the weather service in European countries has been steadily gain- ing in efficiency. The objections to the transfer are : First, that military control is claimed to secure superior promptness, accu- racy, and continuity of record, which is met by the statement that the European weather services are entirely civilian, and our own depends for some of its data upon observa- tions telegraphed by civilian observers from about twenty stations in Canada. Second, it is claimed that only military discipline could keep men in disagreeable or dangerous places ; but civilian observers are found to man the Canadian meteorological outposts in Manitoba, and the mountain-peak stations in Europe. Third, it has been urged that the cost of the weather service would be in- creased by civilian control ; but our military weather service costs more than the civilian services of all the governments of Europe put together. The appropriations are now about $900,000 a year, and some considera- ble reduction that has been made in the cost during the last few years has been due to the employment of civilian aid. Fourth, it has been urged that the military training of the observers would be of value in case of war ; but if this argument is valid, the postal service and all the other Government de- partments should be put under military con- trol. A fifth objection is, that in a civil bureau the appointments would be controlled by political influence. But with the protec- tion of the civil service rules, it is probable that the bureau would be at least as free from favoritism as the army is. It has also been objected that the Government would be breaking its contract with the men of the Signal Corps if they were transferred to a civil bureau. But this difficulty could be met by allowing the military men now in the bureau to choose whether they would go with the Weather Service or stay with the Signal Corps. The chief signal officer is even better aware of the defects of the Weather Service than any outside critic. But the POPULAR MISCELLANY. 715 remedy which General Greely proposes is to replace the second lieutenants in the Weather Service by officers of higher rank, and that future vacancies in the lowest rank of com- missioned officers in the service shall be filled by transfer from the line of the army. This latter provision, by taking away hope of promotion from the sergeants and pri- vates, would deter able men from entering the lower grades, and gaining the experience necessary for filling the higher positions. Moreover, the Weather Service has so ab- sorbed the Signal Corps that the major-gen- eral in command of the army is now urging the formation of a special Signal Corps for actual army purposes. Both these schemes would involve additional expense, but the transfer of the Weather Service to, say, the Department of Agriculture, would secure the same ends by leaving the present Signal Corps free for signaling service, and allowing the meteorological work to be put in charge of scientific men instead of soldiers, while the cost of the work would be lessened instead of increased. Open-air Travel for Consumption. — Dr. Henry L. Bowditch has given the Climato- logical Association an account of the treat- ment which seems to have counteracted a strong tendency to consumption in his own family. In 1808 his father, then thirty-five years old, was undoubtedly threatened with consumption. On August 29th of that year, when thus ill, he started from Salem, Mass., with a friend as his companion and driver, in an open one-horse chaise, for a tour through New England. The trip lasted thirty days and covered 748 miles. During that time he passed from the deepest mental discour- agement and physical weakness through all stages of feeling up to a real enjoyment of life. His journey, though benefiting him immensely, probably did not wholly cure him, but it proved to him the absolute need he had of regular, daily, physical, open-air exercise. Afterward, under walks of one and a half to two miles, taken three times daily, all pulmonary troubles disappeared. He died, thirty years after the journey, from carcinoma of the stomach, his lungs being normal except that one presented evidences of an ancient cicatrix at its apex. He pre- scribed for his children the same regular out-of-door exercise which had been so ben- eficial to him. As soon as they were old enough they were required to take daily morning walks of about a mile and a half. If at any time they were observed to be drooping, they were taken from school and sent into the country to have farm-life and out-of-door play to their hearts' content. In consequence of this early instruction, all his descendants have become thoroughly im- pressed with the advantages of daily walk- ing, of summer vacations in the country, and of camping out, etc., among the mountains. Dr. Bowditch's father had married his cousin, who, after long invalidism, died of chronic phthisis in 1834. Certainly a consanguine- ous union of two consumptives foreboded nothing but evil. Yet, of their eight chil- dren, six are either now alive or they arrived at adult age, married, and have had children and grandchildren, but not a trace of phthisis has appeared in any of these ninety-three persons. Dr. Bowditch sees nothing but the influence of out-of-door life to which this immunity of his family from consumption can be attributed. He has prescribed it, un- der proper precautions, in his practice for years, and says, in conclusion : " I have no objection to drugs, properly chosen, and I almost always administer them ; but if the choice were given me to stay in the house and use medicines, or to live constantly in the open air without them, I should infinitely prefer the latter course in case of my being threatened with pulmonary consumption." Precious Stones in the United States. — Mr. George F. Kunz's report on precious stones to the United States Geological Sur- vey's Division of Mining Statistics shows that the industries of our country in that line, though not very extensive, are more considerably developed than they are gener- ally known to be. The principal localities where gems are sought for systematically are at Mount Mica, Paris, Me., and Stony Point, N. C. Considerable quantities of tour- maline and other gems are produced at Mount Apatite, Auburn, Me. Several locali- ties in North and South Carolina and Ken- tucky have been opened and are worked for the production of zircon and several other comparatively rare minerals which have been looked on heretofore only as gems, but are 716 THE POPULAR SCIENCE MONTHLY. now used for making the oxides of zirco- nium, lanthanum, caosium, etc., to be em- ployed for manufacturing purposes. A con- siderable number of cases of exceptional dis- coveries of gems of rare value are recorded, but they are so scattered as not to admit of grouping either by kind or place. Among the notable collections of gems in the United States mentioned by the author, are the three hundred and thirty-one antique gems of the late Rev. C. W. King, of England, which have been presented to the Metropolitan Museum of Art ; Mr. Maxville Somerville's collection of fifteen hundred specimens of antique jewel-carving art, now on loan in the Metropolitan Museum ; the Rev. Dr. W. Hayes Ward's three hundred ancient Baby- lonian, Persian, and other cylinders, now the property of the museum ; the gem col- lection bequeathed by Dr. Isaac Lea to his daughter ; and the series of precious stones, including about one thousand specimens, which, though not expensive, are the finest in the United States from an educational point of view, belonging to the National Museum. Mr. Kunz also gives some inter- esting fashion-notes about precious stones. They fluctuate in favor. Amethysts and cameos, much sought for ten years ago, are now thrown out. Rubies, already very high, are all the time rising. Topaz is not in de- mand. Coral is going out, while the popu- larity of amber is increasing. The use of Brazilian pebbles has decupled since 1878. The rare stones known as " fancy stones," which were formerly kept only as specimens, are now looked upon as articles of trade, and us part of the normal jeweler's stock. Mr. Kunz, as agent of Tiffany & Co., had a fine collection of North American precious and ornamental stones at the Paris Exposition, of which we have published a laudatory notice by " La Nature." It included three hundred and eighty-two specimens. Botany as a Disciplinary Stndy. — Botany is recommended as a disciplinary study by Mr. Gerald McCarthy. It is much in its favor that the objects with which it deals are convenient of access and full of interest. Among the other advantages that it offers are the adaptation of the study of plants to the cultivation of the aesthetic faculties ; to training the mind to habits of close observa- tion and discriminating judgment, orderly arrangement, and the "logic of systemiza- tion " ; its presenting the phenomena of life in its least complicated manifestations ; plants offering better opportunities for thor- ough study than is practicable with minerals and animals ; the usefulness of the study as a recreation and mental tonic ; and the inex- haustible field for research which it offers. If some object that the technical names are hard, " at the beginning it will serve just as well to use the common vernacular name, or even invent names for one's self. The name is the least important thing one can learn about a plant, and it is not wise for the be- ginner to exhaust his time and patience in trying to choose the most proper of several possible and equally unintelligible names. Rather he should seek to group the speci- mens around common types, thus learning for himself the philosophy of the natural system." But the scientific name must eventually be learned, and it will come easier after the student has observed well for himself. For young pupils, and older ones who are unfamiliar with Latin, Miss Youmans's " First Book in Botany " is rec- ommended as the best manual to begin with. It will lead up to the more advanced works. But more useful than any book is the stu- dent's field outfit, of lenses and knives, needles and trowel, and air-tight specimen- box. Canses of Cn healthiness in Large Cities. — The mere age of London, said Dr. G. V. Poor, in a lecture at the Sanitary Institute, was one of the reasons why it became un- wholesome. Roman London was buried deeply among rubbish of all kinds, much of which was putrescible, and therefore a source of danger in the soil. Ancient Lon- don was well placed and magnificently sup- plied with water through the Thames and many smaller streams. All the smaller streams had become disgracefully foul, "and for very shame had been covered over." That mediaeval London was very unhealthy, a perfect fever-den, there could be no doubt. The causes of the enormous mortality lay in the marshy, undrained soil, fouled with refuse of every kind ; in the filthy state of the unpaved city, and a perfectly swin- ish condition of the houses of the lower POPULAR MISCELLANY. 7*7 orders ; in the ill-nourished and drunken condition of the masses ; in the state of superstition and brutality which made any measure of public health impracticable ; in the bad management in epidemics, and in the incompetence of the medical faculty. There had been a great and manifest im- provement in London. This could be cred- ited to the increase of knowledge among the doctors and among the people generally ; to vaccination and the modern plan of treating infectious diseases by the prompt separation of the patients ; to the cheapness of food, clothing, and fuel, and the facility of obtain- ing fresh fruit and vegetables ; to improved water-supply; and, although the system of sewage disposal was an undoubted evil, it had removed a great deal of filth from dwellings, and the balance was probably so far in its favor. The outlook in the future was obscured by increased overcrowding ; the discharge of sewage into the Thames ; and the increasing danger of the pollution of the water-supply by the accumulation of population along the valley of that river. Clark University. — Clark University, Worcester, Mass., founded by Mr. Jonas G. Clark as an institution for the highest cult- ure, was opened in October, 1889, in the de- partments of mathematics, physics, chemis- try, biology, and psychology, under the pres- idency of G. Stanley Hall. The president is, for the time being, Professor of Psychol- ogy, and, with the assistance of Prof. Sand- ford, will assist students in the departments under that head by instruction, or by con- ference and guidance to literature ; and will direct the work of special students in the history, methods, and organization of edu- cation, elementary, intermediate, and supe- rior, lecturing on them during a part of the year. The professors are H. H. Donald- son in neurology, Edmund C. Sanford in psychology, Warren P. Lombard in physi- ology, F. Mall in anatomy, Albert A. Nichol- son in physics. The methods of instruction include field-work, excursions, "coaching and cram classes," examinations, conferences, lab- oratory work, and lectures. The students are classified as independent, candidates for the degree of Ph. D., special students not candi- dates for a degree, medical students, and preliminary candidates or undergraduates. Twenty fellowships and ten scholarships have been provided by Mr. and Mrs. Clark, affording free tuition to thirty persons. Huron and Iroquois Burials. — In a paper on " Indian Burial in New York," read at the meeting of the American Association, Mr. W. M. Beauchamp said that several modes of burial prevailed in the Huron and Iroquois family at the same time ; but at a later date the influence of contact with Euro- peans and of the custom of adoption was observed. Although the usual position in Indian burial was supposed to be a sitting posture, facing the west, the bodies in a large proportion of the New York graves, while sitting, faced the east. Many burials, both early and recent, were horizontal, and often without deposited articles. For sec- ondary burial, bone-pits were common in the western part of the State, appearing like the Huron ossuaries of Canada, or rising into mounds. The eastern Iroquois, at least after the formation of their league, did not rebury their dead. They used raised tombs, sometimes a mound of earth, and often a wooden structure like a small house. Burial in circles was secondary ; the bodies were laid with their feet toward the center. Graves lined with stones are not frequent, but stone heaps were raised over some graves. Bodies were rarely buried one above another, with an intervening layer of earth. When buried in mounds, or in the bone-pits, they might be placed promiscuously or arranged with care. The mode of sepulture was af- fected by superstition and in consideration of crime. The New York Indians have for a long time been burying their dead much in the manner of their white neighbors. How the Woodcock feeds.— A writer in "Forest and Stream" gives the following account of the way he saw woodcock "bor- ing " for worms one moonlight night : " The birds would rest their bills upon the mud and stand in this position for several seconds, as if listening. Then, with a sudden, swift movement, they would drive the bill its entire length in the soil, hold it so for a second, and then as swiftly withdraw it. Though I watched the birds carefully with the glass, I could not detect the presence of a worm in their bills when they were with- drawn. But a subsequent process gave me 7i8 THE POPULAR SCIENCE MONTHLY. the clew to their method of feeding. After having bored over a considerable piece of ground — a square foot or more — they pro- ceeded to execute what looked comically like a war-dance upon the perforated territory. They also occasionally tapped the ground with the tips of their wings. My intense curiosity to know the possible utility of this process was at length gratified by seeing a worm crawl, half-length, from one of the borings, when it was immediately pounced upon and devoured by one of the woodcock. Presently another worm made its appear- ance, and so on until the two woodcock had devoured as many as a dozen of them. Then the ' vein ' seemed exhausted, and the birds took their leave. I have subsequently studied the philosophy of this method of digging bait, and have come to the conclusion that certain birds are a great deal wiser than certain bipeds without feathers. If you will take a sharpened stick and drive it into the ground a number of times, in a spot which is prolific with worms, and then tap on the ground with the stick for a few minutes, you will find that the worms will come to the surface, and that they will come up through the holes which you have made. I account for it by the supposition that the tapping of the stick somehow affects the worms the same as the patter of rain, and it is a well- known fact that worms come to the surface of the ground when it rains. The antics of the woodcocks after they had made their borings, then, were simply mimetic, and in- tended to delude the worms into the belief that it was raining in the upper world. The worms, being deceived, came up and were devoured. All this may seem ridiculous, but, if it is not true, will some naturalist please state how a woodcock can grasp and devour a worm when its bill is confined in a solid, tight-fitting tunnel of soil, and also how it is enabled to know the exact spot where it may sink its bill and strike a worm ? And further, of all those who have seen a woodcock feed- ing, how many ever saw it withdraw a worm from the ground with its bill ? " The Colorado River of Texas.— The Colo- rado River of Texas is described by Prof. Rob- ert T. Hill as presenting most interesting feat- ures, which rival in some respects those of the Colorado of the West. It begins in the dry arroyas which border the eastern scarp of the " Staked Plain," where it has cut canons nearly a thousand feet deep in the soft Quaternary, Cretaceous, and Triassic strata, recording in their precipitousness both the aridity and the gradual elevation of the region. Between the ninety-seventh and nine- ty-eighth meridians it cuts through an area of Palaeozoic rocks which was the land bar- rier between the Atlantic Ocean and the in- land sea during Mesozoic times. Within the short distance traversed by the Atlantic section of its course, it has worn through the Cretaceous sediments of the plains and now traverses nearly every terrane from the late Quaternary to the earliest Cambrian. " Per- haps nowhere else in the world can be seen a more comprehensive geologic section, a better illustration of sedimentary and igne- ous rocks and their relation to topographic form and economic conditions and other geologic features dependent upon structure, than in that portion of the Colorado which traverses the counties of Burnet and Travis. . . . Here the erosion of the river-basin has exposed nearly ten thousand feet of struct- ure that would otherwise not be exposed, and every bend serves to reveal some inter- esting topographic or geologic fact. . . . When it is added," the author concludes, " that no man has ever explored the deep canons, that the paleontology is almost untouched, that hardly any details of all these grand features have been recorded, one can but feel that the student of geology has here an inexhaust- ible field before him." NOTES. Prof. H. A. Rowland, of Johns Hopkins University, has been elected one of the for- eign members of the Royal Society, in rec- ognition of his determination in absolute measure of the magnetic susceptibilities of iron, nickel, and cobalt ; his accurate meas- urements of fundamental physical constants ; his experimental proof of the electro-mag- netic effect of convection; his theory and construction of curved diffraction-gratings of very great dispersive power ; and the effectual aid which he has given to the progress of physics in America and other countries. Prof. Cannazaro, of Rome, and Prof. Chauveau, of Paris, were elected for- eign members on the same day. An experiment has been made at the agricultural station of Champ de l'Air, Vau- NOTES. 719 dois, in hatching trout ova in complete dark- ness, the water being at a temperature of 5-8° C, or 42-4° F. The hatching was de- layed fifteen days by the darkness. The advantages are claimed, in prolonging the incubation, that the young fry put into the streams in April or May more readily find food than in February or March ; that they are more vigorous ; and that fewer mon- strosities are produced. Experiments in feeding milch-cows, de- scribed in the November " Bulletin " of the Massachusetts State Agricultural Experi- ment Station, attest the great economical value of corn -fodder, stover, and ensilage for the production and quality of milk and cream. The study of the effect of fertilizers on the quality of fruit is recommended by Prof. P. T. Austen as a line of inquiry distinct from their effect on its quantity. This in- volves a wide range of investigation, em- bracing, in fact, all the properties of the plant and the manner in which they are affected by manures, particularly the part played by each chemical substance in the plant and the specific action of fertilizing materials on the formation of those sub- stances ; together with the relation of the different species of plants to their chemical composition, and the extent to which plants of the same family produce substances of the same type. The influence of treatment with drugs opens a parallel line of investi- gation. The Rev. J. Owen Dorsay is preparing a monograph on Indian names, to contain lists, with English meanings, in six different lan- guages— the whole number of names being thirty-one hundred and forty-six. The con- nection between the myths and some of the personal names will be considered ; and cer- tain classes of names — such as color names, iron names, and the names of composite beings — will be treated in detail. The latest published volume of Hen- Richard Andree's "Ethnographical Parallels and Comparisons " deals with such topics as red hair, albinos, games, masks, marks of property, superstitions connected with the chase, " tree and man," circumcision, draw- ing among primitive people, thunderbolts, money for the dead, emotional expressions and gestures, demoniacs and mental dis- orders, etc. The report of Manchester (England) Technical School for the year ending July 31, 1889, shows an increase of students from 2,871 to 3,328. The most important extension during the year was the opening of a spinning and weaving department. The day classes in this department have but a small attendance as yet, but a considerable number of students are attending the evening ses- sions. The suggestion has been made in Lon- don that, as the French have erected the highest tower, the English shall dig the deep- est hole — say on the exhibition grounds of 1851 in Hyde Park. The pit could be fur- nished with an elevator shaft, and lit up by electricity ; and in each stratum there could be an excavated museum with specimens of the minerals, fossils, etc., afforded by it. According to a study by Dr. George N. Kreider, of Springfield, 111., micro-organisms enter the body first by the skin — through le- sions, openings of the sweat-pores, or seba- ceous ducts, or by the sides of the hairs ; and, secondly, by the mucous membrane — through lesions of the membrane, openings of the ducts or follicles, or pockets, sulci, or folds. There are also localized infections, originat- ing in a manner as yet unknown, and giving rise to certain violent diseases ; and universal infections, giving rise to hereditary transmis- sible disease. The severity of the infection varies with the condition of the body as re- gards idiosyncrasy, or strength, or weakness ; the amount of infecting material that gains entrance ; the character of the infecting ma- terial ; and the tissue which it penetrates, and its location. The underlying motions of the Nile Delta are described by Mr. W. J. Flinders Petrie as those of depression on the coast and up- heaval at Ismailia. Above these movements great changes have been made by wind-ac- tion. In some sites at least eight feet of ground have been removed and deposited in the water. This has partly caused the great retreat of the Red Sea head, and tends to form the characteristic swamps of that dis- trict. Formerly the Delta was a desert tract, with valleys inundulated by the Nile. Before historic times the Nile Valley was deep in water, partly estuarine, partly fluvial, and great rainfall then took place. That this was in the human age is shown by the position of worked flints. A memorial to Prejevalski is to be erected on the shore of Lake Issyk-kul. It repre- sents a rock, upon which an eagle is descend- ing, having a map of Asia in its talons and an olive-branch in its beak. The monument will have the inscription, " To the first ex- plorer of nature in Central Asia." A correspondent of " Nature " urges that boys should be tested for color-blind- ness in school — before they go out into life — so that they need not lose the time re- quired for working up to positions on rail- roads or elsewhere in which ability to dis- tinguish colors is essential. A curious story is told, by a correspond- ent of " Nature," of a dog which was struck by lightning and considered dead, but which afterward partly recovered. It continued deaf and blind, and had to depend on its smell for recognition of persons and things. 720 THE POPULAR SCIENCE MONTHLY. OBITUARY NOTES. Prof. Chester S. Lyman, of Yale Uni- versity, died in New Haven, Coon., January 29th, aged seventy-six years. A sketch of his life and works, and a portrait, were pub- lished in "The Popular Science Monthly" for November, 1887. M. Cosson, member of the French Acade- my of Sciences, and author of several mem- oirs on the flora of Algeria and Tunis, died in Paris on the last day of the year 1889. He was President of the Botanical Society of France and Archivist of the Societe d'Ac- climation. Dr. William Ramsay McNab, Professor of Botany in the Royal College of Science, Dublin, recently died, suddenly, of heart disease. He was born in Edinburgh in 1S44, his father, as his grandfather had been, being Curator of the Botanic Garden there. He studied at Edinburgh, where he was also assistant to Prof. Balfour, and at Berlin, practiced medicine for three years, after which, in 18V0, he entered upon a biological career. He introduced important reforms in the method of teaching botany, chiefly by adopting the method of Sachs ; was author of numerous works or papers relating to botany and fossil plants ; was a practical student of geology ; and collected coleoptera. He was appointed in 18S8 Swiney Lecturer to the British Museum of Natural Sciences, and was at the time of his death about to begin a third course on fossil botany. Prof. Lorenzo Respighi, Director of the Osservatorio Campidoglio, Rome, one of the most eminent scientific men in Italy, died December 10th. The people of Manchester interested in the subject have decided to erect in that city a memorial of James Prescott Joule, which shall take the form of a white marble statue, and also to set up a replica in bronze in some public place in the city. An international monument to James Watt is proposed, to be erected at Greenock, his birthplace, and to take the form of a large and thoroughly equipped technical school. Senhor Jose Augusto de Sereza, curator of the zoological department of the muse- um at Lisbon, Portugal, who has recently died, was the author of some useful mem- oirs on African birds, and of museum cata- logues of certain orders. Edouard Phillipps, an eminent French mechanician and engineer, died December 14th, in his seventieth year. He left im- portant works on mechanics and metallurgy, and his " Lectures " on hydraulics and hy- drostatics, published in 1875, was highly appreciated. lie was made a member of the Academy of Sciences, in the Section of Me- chanics, in 1868. Among the recent foreign deaths is that of the Italian physicist Govi, whose name is closely associated with matters relating to the history of science, particularly in his own country. He prepared an interesting group for the International Electrical Exposition of 1881 of instruments which had been used by Galvani, Volta, and Nobili. Julien Sacaze, a young epigraphist and archaeologist of great repute in the provin- cial districts of France, has recently died. He discovered a considerable number of pre- historic monuments and sites in and near the Pyrenaean departments, co-operated in the foundation of the Pyrenaean Association and of a more local society at Comminges, and with Dr. F. Garrigo established the " Revue des Pyrenees et de la France Meri- dionale." The collections which he made in the course of his investigations are described as having been " superb." He left the man- uscript of a work on the " Epigraphy of the Pyrenees," which will be published. Vice-Admirax Cloue, who died in Paris on the 25th of December, was best known for the marine charts he constructed and for his exertions to make of practical value the property of oil in stilling the waves. When he entered the service the French marine was dependent on English or Dutch charts. He substituted for these French charts, many of which he prepared. He was born in 1817 and spent his life in the French naval serv- ice or positions connected with it, was ap- pointed Governor of Martinique in 1872, and afterward held the position of Minister of the Marine and the Colonies. He was a mem- ber of the Bureau of Longitudes, of the Ob- servatory and the Meteorological Council, and had been elected to a seat in the Insti- tute. Mr. E. J. Jones, since 1883 an officer of the Geological Survey of India, who died Oc- tober 15th, aged thirty years, was an associ- ate of the Royal School of Mines and a chemist from the schools of Zurich and Wurzburg. He contributed several geologi- cal and chemical papers to the publications of the Survey. Mr. John Ta vernier Bartram, who died recently at Stake's Point, Bermuda, in his seventy-ninth year, was held in high esteem among scientific men as a naturalist. Dur- ing the forty-two years that he resided at Stoke's Point, says "The Bermuda Colo- nist," he made a collection of birds, fishes, shells, and other natural curiosities, that has long since come to be " one of the things to be seen in Bermuda " ; and for the past twenty-five years no scientific man who visit- ed Bermuda and could get to Stoke's Point ever failed to pay him a visit. He contrib- uted articles to the local press on the natu- ral history and geology of Bermuda, and prepared hand-books on the cage-birds and the shells of the island. DAVID RITTENH0U8E. POPULAR SCIENCE MONTHLY. APRIL, 1890. SCIENCE m THE HIGH SCHOOL.* By Prof. DAVID STARE JORDAN, PRESIDENT OF THE UNIVERSITY OF INDIANA. THE purpose of science-teaching as a part of general education is this — to train the judgment through its exercise on first- hand knowledge. The student of science is taught to know what he knows and to distinguish it from what he merely remembers or imagines. Our contact with the universe is expressed in what we call science. Throughout the ages, the growth of the human mind has been in direct proportion to the breadth of this contact. To the man without knowledge of science, the universe seems small. Science is our perception of realities ; and as the realities come year by year to occupy a larger and larger place in our life, so the demand for more and better training in science will long be an urgent and growing one. But science should hold its place in the schools by virtue of its power as an agent in mental train- ing, not because of the special usefulness of scientific facts, nor because knowledge of things has a higher market value than the knowledge of words. The time will come when the study of the objects and forces of nature will be as much a matter of course in all our schools as the study of numbers, but the science- work of the next century will not be the work we are doing now. The science in our schools is too often a make-believe, and the schools will lose nothing when every make-believe slips out of the curriculum. Deeply as I am interested in the progress of science, both in school and out, with Prof. Huxley " I would not turn my hand over " to have biology taught in every school in the land, if the subject is taught through books only. To pretend to do, without doing, is worse * Read before the Indiana State Teachers' Association, December 26, 1889. vol. xxxvi. — 46 72 2 THE POPULAR SCIENCE MONTHLY. than not to pretend. The conventional " fourteen weeks " in sci- ence gives no contact with nature, no training of any sort, no information worth having ; only a distaste for that class of scat- tering information which is supposed to be science. There is a charm in real knowledge which every student feels. The magnet attracts iron, to be sure, to the student who has learned the fact from a book, but the fact is real only to the student who has himself felt it pull. It is more than this, it is enchanting to the student who has discovered the fact for himself. To read a statement of the fact gives knowledge, more or less complete as the book is accurate or the memory retentive. To verify the fact gives training ; to discover it gives inspiration. Training and inspiration, not the facts themselves, are the justifi- cation of science-teaching. Facts enough we can gather later in life when we are too old to be trained or inspired. What is true of one science is true of all in greater or less de- gree ; and I may take the science of zoology for my illustration simply because it is the one nearest my hand. In very few of our high schools has the instruction in zoology any real value. For this unfortunate fact there are several causes, and some of these are beyond the control of the teachers. In the first place, the high-school course is overloaded, and the small part of the course given to the sciences is divided among too many of them. A smattering of one science is of little value, either for discipline or information. A smattering of many sciences may be even worse, because it leads the mind to be content with smattering. Indeed, so greatly have our schools sinned in this respect that many writers on education seem to regard science as synonymous with smattering, and they contrast it with other branches of learning, which are supposed to have some standard of thoroughness. Most of our colleges have, at one time or other, arranged courses of study not approved by the faculty, in response to the popular demand for many studies in a little time. Such a course of odds and ends is always called " the scientific course," and it leads to the appropriate degree of " B. S." — Bachelor of Surfaces. The high school can do some things very well, but it will fail if it tries to do too much. Unfortunately, the present tendency in our high schools is in the direction of such failure — to do many things poorly rather than a few things well. Each high school aims to give a general education ; to be a university in a small way — a university for the poor — a poor university. In the words of Lowell, " The public schools teach too little or too much ; too little, if education is to go no further ; too many things, if what is taught is taught thoroughly. And the more they seem to teach, the less likely is education to go further; for it is one of the weaknesses of democracy to be satisfied with the second best, if it SCIENCE IN THE HIGH SCHOOL. 723 appear to answer the purpose tolerably well and is cheaper, which it never is in the long run." In other words, we try to satisfy the public by a show of teaching those subjects which we can not really teach. And so, in the sciences we study books instead of Nature, because books are plenty and cheap, and can be finished quickly, while Nature herself is accessible only to those who want something of her. The high school would do well not to attempt to give a general view of science. This is possible only in a " Chautauqua course " or in a "school of all sciences." It is better to select some two or three of the number, a physical and a biological science, perhaps, and to spend the available time on these. The choice should depend mainly on the interest or the skill of the teacher. Teach those sciences that you can teach best. President Hill, of Rochester University, has well said : " Thou- sands of our youth have studied chemistry without ever seeing an experiment, physics without seeing an air-pump, and astronomy without ever looking through a telescope. A professor of the ancient type maintained that this is a great advantage, like the study of geometry without figures, because it stimulates the imagi- nation. It is an invigoration of stupidity and conceit, sealing the mind to reality by substituting subjective fancies for experimental proofs, and the pretense of knowing for clear ideas. Its effect upon the morals is as pernicious as its effect upon the mind, for it weakens the reverence for truth and engenders the habit of mental trifling." Even so wise a schoolmaster as Dr. William T. Harris excludes science-teaching (and science-teaching with him means simply giving information about scientific subjects) from the funda- mental requirements of education, because the knowledge of na- ture is not one of the five windows through which the soul looks out on life. These windows, according to Mr. Harris, are reading and writing, grammar, arithmetic, geography, and history. The simile is a happy one. The soul, confined in the watch-tower of mediaeval education, looks out on the world through these five windows, and they are but windows, for they give no contact with the things themselves. The study of nature throws wide open the doors, and lets the soul out to the fields and woods. It brings that contact with God through his works which has been, through all the ages, the inspiration of the poets and prophets, as well as of those long-despised apostles of truth whom we call men of science. A second difficulty is this: Our towns will not pay for teach- ers enough to do the work as it should be done, and of the few teachers we have the people make no demand for thorough prepa- ration. Very few of them are broadly educated or have had any 724 THE POPULAR SCIENCE MONTHLY. scientific training whatever. And such teachers are expected to teach a dozen subjects each, and therefore have no time to make good their defective preparation. Thus good teaching of science can not be expected, for streams do not rise higher than their sources. The only remedy for these conditions seems to lie in the gradual education of the people. A series of object-lessons, showing the difference between a good teacher and a poor one, is the most effective means of causing good work to be appreciated. But taking things as they are, even with uneducated teachers and teachers crowded for time, fairly good work may be done by the use of good methods. A great deal will depend, not on the kind of books you use, but on the kind of books you avoid. Most of the current text-books of elementary zoology are simply per- nicious so far as your purposes are concerned. Even if these books were well digested and accurate in their statements of fact, which is rarely the case, they are based on incorrect principles. They are not elementary but fragmentary in their character. It is a great mistake to suppose that, because a book is small and says very little about each one of the animals of which it treats, it is thereby rendered elementary. Fragments are not necessarily elements. A fragment of rock is as hard to digest as a bowlder. Elementary work in science should treat of but few things, but the impressions it leaves with the child should be very clear ones. The ideas derived from the common text-books are of the vaguest possible character. These books are the parasites, not the allies, of science. They bear the same relation to the progress of science that barnacles bear to the progress of a ship. If you keep clear of these, you can not go far astray. Let us recall the words of Agassiz to the publisher who tried to induce him to write a school- book on zoology : " I told him," he said, " that I was not the man to do that sort of thing ; and I told him, too, that the less of that sort of thing which is done the better. It is not school-books we want, but stu- dents. The book of nature is always open, and all I can do or say shall be to lead students to study that book, and not to pin their faith to any other." And at another time he said, " If we study Nature in books, when we go out of doors we can not find her." The essential of method is that we allow nothing to come be- tween the student and the object which he studies. The book or chart or lecture which can be used in place of the real thing is the thing you should never use. Your students should see for them- selves, and draw their own conclusions from what they see. When they have a groundwork of their own observations, other facts can be made known to them as a basis for advanced generaliza- tions, for the right use of books is as important as their misuse is pernicious ; but work of this sort belongs to the university rather SCIENCE IN THE HIGH SCHOOL. 725 than to the high school. You do not wish to have your students tell you from memory the characters of the Sauropsida as distin- guished from the Ichthyopsida. What you want is the answer to their own questionings of the frog and the turtle. I was lately present at a high-school examination in zoology. The teacher gave a number of the stock questions, such as " De- scribe the Gasteropoda." " What are the chief differences between the domestic turkey and the turkey of Honduras ? " " How do Asiatic and African elephants differ ? " " On which foot of the ornithorhynchus does the webbing extend past the toes ? " and so on. At last he said : " I will now give you a practical ques- tion : A few days ago we had a frog in the class, and all of you saw it ; now write out all the characteristics of the sub-kingdom, class, and order to which the frog belongs/' This is all useless. The definitions of these classes and orders do not concern the child. To the working naturalist these names are as essential as the names of the stations on the road to a rail- way engineer. They belong to his business, but the names and distances of railway stations do not form part of any good work in primary geography. You do not need to teach your students that vertebrates are divided into mammals, birds, reptiles, batra- chians, and fishes. It is not true in the first place, and, if it were, it is not relevant to them. Stick to your frog, if you are studying frogs, and he will teach you more of the science of animals than can be learned from all the memorized classifications that you can bracket out on a hundred rods of blackboard ! The prime defect in our schools is not, after all, that the teach- ers do not know the subjects they teach, but that they do not know nor care for the purpose of their teaching. In other words, they do not know how to teach. The book is placed in their hands by the school board, and they teach by the book. If the book comes to them wrong-side up, their teaching is forever inverted. That this is true, the statistics gathered last year from the high schools of Indiana, by Prof. Evermann, very clearly show. It is no wonder that a superintendent is needed for every dozen teachers. A good teacher should know the end for which he works, and then he can adapt his means to fit this end. I once visited a large high school, one of the best in the coun- try, with a science teacher whose studies have won him the re- spect of his fellow- workers. But for some reason, on that day at least, he failed to bring his own knowledge into the class-room. I heard him quizzing a class of boys and girls on animals — not on the animals of the woods and fields, not on the animals before them, for there were none, but on the edentates of South Amer- ica. An especial point was to find out whether it is the nine- banded armadillo (novemcinctus) or the three-banded armadillo 7 26 THE POPULAR SCIENCE MONTHLY. (tricinctus) which does not dig a hole in the ground for its nest. The book, written by a man who did not know an armadillo from a mud-turtle, gives this piece of information. It was in the lesson, and the students must get it. And on this and like sub- jects these boys and girls were wasting their precious time — precious because, if they do not learn to observe in their youth, they will never learn, and the horizon of their lives will be always narrower and darker than it should have been. Already the work of that day is a blank. They have forgotten the nine-banded armadillo and the three-banded, and so has their teacher, and so have I. All that remains with them is a mild hatred of the arma- dillo and of the edentates in general, and a feeling of relief at being no longer under their baleful influence. But with this usually goes the determination never to study zoology again. And when these students later come to the college, they know no more of science and its methods than they did when at the age of one year they first cried for the moon. Darwin tells us that his early instruction in geology was so " incredibly dull " that he came to the determination, afterward happily changed, " never so long as he lived to read a book on geology or in any way to study the subject." I once had a student, well trained in the conventional methods of non-science, who was set to observe the yeast-plant under the microscope. He had read what the books say about yeast, and had looked at the pictures. So he went to work vigorously. In a short time he had found out all about the little plant, and had made a series of drawings which showed it very nicely. By and by some one noticed that he was working without any object- glass in his microscope. He had not seen the yeast -plant at all, only the dust on the eye-piece. This is the vital fault of much of our teaching of elementary science. It is not real ; it is not the study of nature, only of the dust-heaps of old definitions. Yet nothing is easier than to do fairly good teaching, even without special knowledge or special appliances. Bring out your specimens and set them before the boys and girls. They will do the work, and do it eagerly ; and they will furnish the specimens too. There is no difficulty about materials. Our New World is the " El Dorado " of the naturalists of Europe. You can get ma- terials for a week's work by turning over a single rotten log. I once heard Prof. Agassiz say to an assembly of teachers, and I quote from him the more freely because he gave his life to the task of the introduction of right methods into American schools : " Select such subjects that your students can not walk out with- out seeing them. If you can find nothing better, take a house-fly or a cricket, and let each one hold a specimen while you speak. . . . There is no part of the country where, in the summer, you ETHICS AND RELIGION. 727 can not get a sufficient supply of the best of specimens. Teach your pupils to bring them in. Take your text from the brooks and not from the booksellers. ... It is better to have a few forms well studied than to teach a little about many hundred species. Better a dozen forms thoroughly known as the result of the first year's work, than to have two thousand dollars' worth of shells and corals bought from a curiosity store. The dozen animals will be your own. . . . You will find the same elements of instruction all about you wherever you may be teaching. You can take your classes out and give them the same lessons, and lead them up to the same subjects in one place as another. And this method of teaching children is so natural, so suggestive, so true. That is the charm of teaching from Nature. No one can warp her to suit his own views.

"XT~0 subjects occupy men's attention more than morality and -L ^ religion. They are patent, ever-present facts, always intrud- ing themselves on our thoughts, and always demanding consider- ation. They have formed subjects of human reflection since the race of man began ; nations have wrought out practical schemes, philosophers have invented systems ; thousands of generations have talked over individual facts and ideas. Yet men are far from being at one on the nature of the two and the relation be- tween them. One opinion, held widely in our own times, is that religion is the creator of ethics — an opinion not unnaturally suggested by the fusion of ethical and religious ideas and practices which exists among us. The masses of our communities are reared in a re- ligious atmosphere. Their first impressions of duty and right are colored by religious ideas and supported by religious sanctions. The most generally accepted and revered ethical codes are con- tained in the sacred books, and the most prominent preachers of morals are ministers of religion. Our courts of law dispense jus- tice in the name of the Divine Being. Kings rule by the grace of God, and the Congress of the United States has stamped a decla- ration of the national trust in God on a silver coin. In many countries religion appears at the birth of a child, to initiate it by a symbolic ceremony into the Church ; almost everywhere when life is departing religion comes to care for man's future ; and it is religion which announces the close of life by the solemn depo- 7 28 THE POPULAR SCIENCE MONTHLY. sition of the body in the grave. There are many who hold that both the content and the impulse of ethical life are given by re- ligion ; that man can neither know nor do right without divine aid ; and that human virtue, apart from the supernatural element, is a delusion and a snare, since it allures men to a fatal self- dependence by holding out the false hope that they can be really good without divine aid. This is the annihilation of morality in the ordinary sense of the term. On the other hand, the opinion is held that religion and morals are wholly distinct, neither in any wise affecting the fundamental conceptions or the practical development of the other. According to this view, the two start from different points, have regard to different objects, look to different aims, and follow different meth- ods. Sometimes this distinctness is represented as belonging only to the ideal conception of religion and ethics, sometimes it is claimed as a characteristic of the historical development of the two. Religion, it is said, deals with God, ethics with man ; and this difference, it is held, severs the two by a world-wide interval. Such a position may be maintained both by those who accept and by those who reject a supernatural divine revelation of truth. A believer in revelation might hold the atonement of Christ to be a distinctively religious fact, while he might regard the ethical teaching of Jesus or Paul as the product of human experience. Still another view considers the two as different indeed in origin and modes of development, but, since both are essential ele- ments of life existing from the beginning, as acted on and inter- penetrated each by the other. It may be held, for example, that the posture of mind necessary to produce ethical convictions is, if not created, at least modified by the religious theory, the con- sciousness of the presence of the Deity deepening the instinct or conviction of duty toward one's fellow-men ; or that, in the inverse direction, the sentiment of duty toward the Deity is quickened by the feeling of human obligation ; or, again, that the hope of reward or the fear of punishment from the supernatural powers may fur- nish a strong motive for right-doing ; or that the ideals of duty, constantly transcending practice, and embodied in the Deity, may be an ethically elevating influence. According to this view, the present ethical religious thought of the world is the product of a long series of interactions between ethical and religious ideas which have grown up more or less independently. In order to test the correctness of these various opinions, we must consider briefly the history of the development of men's religious and moral ideas and practice. Our knowledge of this history can be only a general one : we have not the data necessary to describe the beginning of any line in human life ; we do not know with certainty how man formed his first notion of the super- ETHICS AND RELIGION. 729 natural, or under what conditions his moral life began. There are hypotheses or surmises which we may think natural or probable ; but these must, of course, be distinguished from what is known to be fact. Let us begin by defining the principal terms of our in- quiry. Religion is the body of beliefs and practices pertaining to the nature and worship of the Deity, and determining man's effort to propitiate him and secure his aid ; ethics is the body of beliefs and practices regulating the conduct of man to man. True, this distinction seems to be sometimes abandoned : the Deity is said to be pleased by ethically right conduct, or a religious ceremonial comes to be regarded as having an ethical character. But even in these cases the distinction really exists. For, the conduct held to be acceptable to God not only relates to intercourse between human beings, but exists as a social custom before it is approved by religion ; and the religious ceremonial, primarily designed to secure the divine favor, is ethical only in so far as it involves rela- tions among men. This distinction is not affected by the question respecting a divine revelation of truth, for such a revelation might naturally treat duties to God and duties to man as separate sorts of obligation. Before, however, entering on the discussion of the subject, it may be proper to ask whether our opinion as to the genesis of ethical practice must be modified by belief in a supernatural, divine revelation of truth. I do not inquire whether such reve- lations have really been given. It is sufficient for our present purpose to ask whether the objective content of the alleged reve- lation is of such character as to take it out of the line of natural human development. How stands the case, for example, with the ethical teaching of the Hindu, Persian, and Arabian sacred books ? The morality of the Koran is in part high and pure, doubtless an advance on the current usage of Mohammed's time. Yet, leaving out of consideration what was borrowed from Jewish and Chris- tian sources, it contains nothing that may not have been the product of human reflection. The social life of the Arabs of that period was comparatively well organized, and Mohammed under- took for the most part only to modify existing customs — to restrain, for example, the rights of divorce and retaliation ; and the duties of honesty, justice, kindness, and mercy which he enjoined were such as would naturally suggest themselves to a large-hearted and keen-sighted man anxious to secure the permanence of a new faith and the well-being of his countrymen. The same thing may be said of the moral codes of Zoroaster, the Veda, and Buddha. Of these the last named is the most remarkable so far as regards purity and depth of ethical perception. It has permanent value quite apart from the Buddhist idea of happiness and perfection as consisting in absolute freedom from thought and feeling ; its fun- 73o THE POPULAR SCIENCE MONTHLY. damental principles of self -culture and self-denial involve a noble and spiritual conception of life, and are capable of leading to the most admirable results. But, even with the obscurity that rests on the beginnings of Buddhism and the moral-religious development that preceded it, none of us will be inclined to deny that it is the outcome of the experience and thoughts of the time. Such, also, appears to be the case with the ethical codes of the Bible. The ordinary social duties which are enjoined in the Old Testament and New Testament, such as honesty, truthfulness, sobriety, kindness to the poor, are common to many times and peoples. All the moral requirements of the Decalogue are found among the Egyptians at a period earlier than that usually assigned to Moses, Even the nobler qualities of love to man, forgiveness of injuries, denial of self, are not without parallel in other communities. In some cases a process of natural development may be observed in the biblical ethics. The prophets enjoin on the Israelites justice and kindness to their own countrymen, but their view does not extend beyond their own land ; one of the later law-books (Lev. xix, 18) contains the precept, " Thou shalt love thy neighbor as thyself," but it de- fines neighbors as " the children of thy people " ; the great Jewish lawyer Hillel, toward the end of the first century before the begin- ning of our era, announced as the central principle of conduct that a man should not do to others what he would not have them do to him ; Jesus put this principle into positive shape (the same thing substantially existed among the Chinese and Greeks). The ethical treatise of the Egyptian Ptah-hotep, said by Maspero, Renouf, and other eminent scholars to be the oldest book in the world (its date is put before 2000 b. a), contains a moral code remarkable for loftiness and spirituality ; it enjoins gentleness, forgetting wrong, contentment, kindness, avoidance of pride, of hardness of heart, and of bad temper. It would appear, from the codes of peo- ples for whom no divine revelation is claimed by us, that man by his unaided efforts has come to the knowledge of the best prin- ciples and practices of morality, has not only made admirable rules of conduct, but has perceived that the essence of goodness lies in the character of the soul. If this be so, it is unnecessary to suppose a supernatural divine revelation to account for the ethical phenomena of society. It might be said, indeed, that all this ethical development proceeds from a primitive divine reve- lation. But this statement rests on no historical proof, nor would it explain the fact that the ethical progress of a nation goes hand in hand with its growth in civilization. If the ancient Hebrews received their ethical code directly from God, whence comes it that manners were milder in Ezra's time than in the pre-exilian pro- phetic period, less mild in the days of David, and comparatively rude in the period of the Judges ? It would be singular if the ETHICS AND RELIGION. 731 generations which stood nearest the revelation were least affected by it. Religion consists of creed and ritual. What is the origin and nature of these facts ? The religious creed is the embodiment of man's view of the supernatural constitution of the universe. It defines the origin and nature of the powers which stand outside of human life, and the manner in which they brought into being the whole system of things ; it describes the character of the relations between them and men, resulting from the attributes of the dei- ties. From these premises the ritual law prescribes the processes by which the favor of the supernatural powers is to be secured. The main article of the creed, the theology or doctrine of the deity, is the result of reflection. Man demands a ground for the external world, which he naturally at first thinks of as animated by spirits like his own. To these spirits he ascribes passions such as he is conscious of in his own nature. Every object becomes for him a living creature ; he refers every phenomenon to an invisible spiritual nature. In process of time he separates the agent from the object or phenomenon, and regards it as an independent power, endowed with such qualities as are suggested by the particular conditions of the case. A deity thus arises, who is gradually in- vested with a history. Myths which embody natural phenomena or ritual processes, legends which spring from vague recollections of historical occurrences, symbolical stories expressing ethical and other thought gather around his person, and gradually build up for him a distinct individuality. The qualities ascribed to him are modified generation after generation and age after age in ac- cordance with the social development of the community. Starting from his undefined, primitive character, the deity becomes a war- rior or a sage, malevolent or beneficent according to the conditions which determine his growth. His ethical nature at any given time will reflect the moral ideas of the community at that time. Man's consciousness of the two opposing elements of good and evil in nature will lead him to apportion beneficial and hurtful attributes and acts among the gods. Those of them who are good will be credited with the best qualities that men can think of, and the bad will tend to become as bad as can be. The latter may then retain their independence and autonomy (as in the Persian religion), or they may bo degraded to a subordinate position and retain their power and existence only through the sufferance of the supreme Deity (as among the Hebrews). This process of constructing the deity supposes a parallel pro- cess of self -analysis by man. He finds himself forced by all the conditions of life to inquire into his own nature and needs, and thus gradually builds up an anthropology. This belongs in itself to the domain, not of religion, but of science. But it is the neces- 73 2 THE POPULAR SCIENCE MONTHLY. sary basis of religion. Without the knowledge of man the knowl- edge of God would be useless for religious purposes ; the two go hand in hand. The former springs from and is applied to all the relations of human life. The part of it which comes to be distinct- ively religious is the consciousness of dependence on God, with all the convictions and feelings which therewith connect themselves. This consciousness has a history similar to that of man's theo- logical creed. It is at first simple and fleshly, relating to man's animal passions and needs ; it is purified by time, growing till it attains a well-developed ethical-spiritual shape. From being a creature who needs only food and raiment, man comes to be a highly endowed soul with aspirations after moral perfectness, and at each step the deity must be able to satisfy his needs. The history of the genesis of things is in itself no more re- ligious than • anthropology. How the world, and man, and the gods came into existence are essentially scientific questions ; they assume a religious aspect from the fact that they are interwoven with man's really religious conceptions. The first attitude of the human mind on these points is one of indifference ; men accept known facts without question. A period of reflection follows ; interest is felt in the problem of origins. The construction of the world is assigned, of course, to the supernatural powers ; the pro- cess of creation is thought of as similar to human methods of work : the world is said to have issued from an egg, or to have been formed from the limbs of a giant, or to have been fashioned in some way familiar to man. The genesis of man is explained in a similar manner. He is born of divine or half -divine parents, or fashioned out of stone or clay. The gods themselves are supposed to have issued from earlier gods, who are held to have come into existence in some far-off time out of primitive material, commonly water. The whole process is one of reflection — it is man's effort to embody in living form the forces which he conceives to have been at work in the creation of the universe. It is his first attempt at scientific analysis and construction. This theological exposition of the world is a necessity of human thought ; man can no more ignore it than he can cease to breathe. It is equally necessary that he should define his own relation to the unseen powers around him. They are believed to determine, in large measure, his weal or woe : they send rain and storm, pestilence and famine, sunshine and food ; they smite with disease, or maintain in health ; they give victory over enemies, and decide the success or failure of all undertakings. In order to secure their favor and aid, he must know what it is in his conduct that pleases or displeases them, and by what processes their anger may be averted and their good-will obtained. At first, the sup- posed requirements of human conduct are altogether ceremonial; ETHICS AND RELIGION. 733 but they gradually assume an ethical character. Man ascribes his own conscience to the deity ; he can not think of the divine as morally inferior to himself; the divine demands are those which man recognizes in his own conscience. The forms of the ritual are developed out of social customs. The first idea of the primitive man probably is that the deity is to be propitiated by friendly attentions or by a gift, as a human chieftain or other person would be, and the more precious the gift the better. A man would therefore offer that which he held to be dearest to him— even his own flesh and blood; a human life would be considered the costliest of offerings. All the ceremonies of so- cial life were naturally transferred to the sacrifice of the gods. As eating was so prominent a fact for man, he prepared feasts for his deities ; tables were spread, and food and drink were offered. It was assumed that the gods shared men's love of praise ; hymns were sung celebrating the divine power and glory. Sometimes a malevolent nature was ascribed to the deity : it was supposed that he was jealous of man's prosperity, and that his displeasure was to be removed by the sacrifice of something which the man esteemed valuable— a costly ring, for example, would be thrown into the sea ; but woe to the offerer if it should be found in a fish and returned to him! Out of this primitive material of sacri- fices, feasts, praise, and thanksgiving, have arisen all the compli- cated liturgies and rituals of the world. The outward form of them has followed the customs of society. That which in social intercourse came to be considered seemly and reverent was adopted as the proper attitude toward the gods. The dress of the ministers of religion, words of supplication or praise which they employed, the posture of the worshipers, have always been determined by the forms of human society. The basis of religious service is man's desire to secure the friendship of the deity, its form is determined by the social proprieties. These last must therefore be looked on as an accessory of religion, important as means, but not belonging to its essence.* Parallel with the religious development is the growth of moral ideas and the elaboration of systems . of practical ethics. These also are founded in the nature of things, inasmuch as they have never failed to appear in human society. It is not our purpose here to attempt an explanation of the origin of those instincts on which society is founded, and which furnish the basis of moral character. So far as we know, the complementary instincts of self -maintenance and sympathy are inseparable from the nature of man. They are found, indeed, in the lower forms of being, and were doubtless inherited by man from his ancestors of a lower type ; but, in any case, they are now to be considered essential * It is not here intended to deny that ritual may be a symbolic representation of ideas. 734 THE POPULAR SCIENCE MONTHLY. parts of the human constitution, and out of them spring all the details of ethical life. Nor are we called on to discuss the origin of the sentiment of obligation, since we are warranted in holding that it also belongs to the essence of human nature. No man, so far as our information goes, has ever been found to be destitute of it, and, as far as concerns our world, it may be regarded as found- ed in the nature of things. It is the basis of all moral develop- ment. The only question that need be asked is whether it is at all dependent on religion for its essential character — that is to say, at the moment when this sentiment was shaping itself in the mind of man, was its genesis at all conditioned on the recognition of the supernatural ? In the decision of such a question we can be guided, of course, only by data of our own consciousness. But the reference to the supernatural does not seem to help the matter much, since we meet here at the outset this same sentiment of obligation. What is the origin of the convictions of duty which man feels toward the unseen powers around him ? Does it spring from the recognition of their superiority of position ? But this is nothing more than the recognition of a relation which involves the power of harming or helping in the superior being, and, so far as the same power is supposed to reside in men, the same sentiment toward them will arise. Or does the feeling of duty toward the gods come from the recognition of rights belonging to them ? Then it does not appear why there should not be a similar recognition of rights belonging to men, since in the ear- liest conceptions there is no difference between man and the deity, except in the point of power. It does not seem, therefore, that religion has been effective in producing the feeling of obligation, except so far as it has added to the objects toward which this feel- ing was directed. There would be just as much ground for hold- ing that the sentiment of religious obligation sprang from the feeling of duty which arose between man and man. In point of fact, no doubt, both were products of the same primitive elements of man's constitution. The recognition of an object implies the recognition both of its nature and of those powers in it by which it affects us for good or for bad, and from the interplay of these ideas comes finally the conviction that the object has certain rights ; we first perceive and estimate the personality, and then, through experience and reflection, come to the conclusion that it is obligatory on us to allow it such freedom as is consistent with the freedom of other personalities. The degree of liberty we allow will be, in general, in proportion to the power of the per- sonality : men can be controlled by equal powers ; the gods, wielding irresistible power, will enjoy perfect liberty. The two sorts of feeling of duty, toward man and toward the deity, grow by mutual action and reaction ; each, as it becomes more refined ETHICS AND RELIGION. 735 and powerful, communicates something of its qualities to the other. In man's progress in culture of soul there is no part of his nature that does not affect and is not affected by all other parts. Let us pass on to the details of man's ethical codes. It is gen- erally agreed that the great mass of these spring from the ex- periences of human intercourse. The ordinary moral rules of life have arisen from men's observation that without them society is not possible. Such is the origin of the feeling against theft, mur- der, and falsehood. The family life is dependent on the subordi- nation of children to parents, and the tribal or national life on the obedience of subjects to rulers. The early particular per- ceptions of the law of kindness arise from a compromise between the instincts of self -development and sympathy. A man helps his fellow-man, but not more than is consistent with the mainte- nance of his own interest. There are special instincts, like that of maternal love, which carry with them absolute self-abnegation. In process of time moral principles acquire a certain universality, and are embodied in ideal forms of men or gods, and these ideals and principles assume an independent shape and enter as inde- pendent forces into moral life. Even the broadest and most un- selfish ethical conceptions and usages of our best developed societies are thus to be traced back to the habits of thought which arise from social intercourse. The results of the ethical thought of society are adopted by religion. Observation, as is remarked above, teaches that so soon as the constitution of the community becomes distinctly moral, its religion assumes the same tone — the content of the divine character becomes moral, and the deity is conceived to be pleased by conduct which is in accord with his character. It need not be thought derogatory to religion that it should depend on the ex- periences of human society for its moral teachings. The essence of religion is not the content of the divine personality, but man's desire to put himself in sympathy with the divine. The ethical character with which man enters into relation is, of course, of extreme importance ; but the human mind can not truly appro- priate thoughts which it has not learned by experience, and no divine ideal would be effective which had not previously been wrought out by the mind itself. Such an ideal may exert a powerful influence on life, but only on condition that it correspond with ethical conceptions held by the community in which it exists. If there is a conflict between these two standards, there is in most cases no doubt as to which of them will determine conduct : men will follow their own con- victions, preserving a respectful attitude toward the divine, but ignoring its guidance in this point. Illustrations of this fact are 736 THE POPULAR SCIENCE MONTHLY. probably to be found in all advanced societies. Plato wished to banish the poets from his Republic because he feared the influ- ence of the immoral stories they told of the gods. But his very protest shows that he and the members of his circle had risen above the moral plane of these stories ; and, in fact, it is clear from the writings of the period, especially those of JEschylus, Sophocles, Plato, Xenophon, Demosthenes, not to speak of the Stoics, that the moral conduct of men was determined at that time, not by the example of the gods, but by such social consid- erations as influence us at the present day; it would no doubt have been thought ridiculous if, for example, a man had adduced precedents in the lives of Zeus or Hermes or Aphrodite in de- fense of conduct condemned by the laws and usages of Athens. A similar ineffectiveness of divine precedent may be observed in Christian societies of our own time, who listen Sunday after Sun- day, devoutly but with complete ethical indifference, to proced- ures represented in the Old Testament as based on divine com- mand, but foreign to our modes of thought. I once heard from a learned clergyman an argument of an hour to show that Abra- ham's purpose to offer his son could not reasonably be regarded as an example for us, since Abraham was certain that he had the divine command, while we are not warranted in believing that we enjoy personal direction from God of that sort. The occasion of the discourse was the shocking history of a citizen of Massachu- setts, who, aided and abetted by his wife, sacrificed his child in obedience to a supposed command from God. But people gener- ally disposed of the matter more simply by saying that the man was crazy, and so he was adjudged to be in a court of law ; the general feeling was that no sane man could thus go counter to the ethical principles of our time. The command to exterminate the Canaanites, though it may be vaguely regarded by many as having been right at that time, would not now be pleaded by the general of an army or by a minister of war as authority for wholesale slaughter of enemies. Theoretically these things are widely looked on as divine ; but the popular instinct, with easy illogicalness, decides that for some reason or other they do not belong to our times. The explanation, of course, is simple : these procedures were the product of half -barbarous communities, or at any rate of a period when men saw nothing wrong in them ; they were repudiated by the moral sense of the later Jews. Slavery, recognized as lawful in the Hebrew and Christian Scriptures, is now condemned by the civilized world ; and the New Testament teaching on this subject is explained, by those who hold the bibli- cal ethics to be absolutely correct, as a wise reticence : the apostle Paul, it is said, refrained from interfering with the social insti- tutions of his time, and trusted to the regenerating power of the ETHICS AND RELIGION. 737 principles of the gospel. It is true that there is a spirit in the New Testament which is antagonistic to the enslaving of human beings. But it is also true that Paul saw no incompatibility be- tween slavery and Christianity, and it is only recently that the Christian world has come to a definite conclusion on this point. It is not long since devout men in England, Russia, Brazil, and the United States defended slavery on biblical and moral grounds ; and the present condemnation of it is to be regarded as a product of the modern social movement toward the recognition of all human rights. The relation of divine standards to human experience is illus- trated in our own times by the discussions on various points of social morals. The Catholic Church, following what it supposed to be the New Testament teaching, affirmed the perpetuity of the marriage relation and the impossibility of divorce. There is a difference of opinion among biblical expositors as to the meaning of the passage in which the Founder of Christianity has ex- pressed his opinion on this point (Matt, v, 32) ; some hold that there is one scriptural ground of divorce, others that there is none. Modern legislators and social philosophers, however, proceed without reference to the biblical rule. The old church law has been abandoned in most countries, and in the discussions which take place in private circles the arguments on the sub- ject are based not on scriptural grounds but on considerations supposed to connect themselves with the well-being of society. There are many questions for the decision of which there is no specific religious authority; they have arisen from distinctly modern conditions of life, of which the older religious books, of course, take no note. Such questions may often, perhaps always, be brought under general ethical principles announced in the Bible. But the particular application of these principles, the practical decision of present questions of duty, is determined by existing social conditions. Whether capital punishment should be abolished, how far the use of alcoholic drinks should be allowed or prohibited by the state, whether parks and museums should be thrown open to the public on Sundays, whether the theatre should be favored or opposed — these questions are all dis- cussed on modern social grounds. Has religion contributed any idea to ethics ? It might seem at first view that this question must be answered in the affirma- tive. The Church has at various times imposed laws on the world. The ethical life of Europe has been deeply affected by the church law of divorce. The celibacy of the clergy, a purely eccle- siastical enactment, has had far-reaching moral consequences. In all times and countries the ministers of religion have had more or less to do with the establishment of customs and laws relating vol. xxxvi. — 47 738 THE POPULAR SCIENCE MONTHLY. to morals. And yet it must be considered doubtful whether, by the authority of ministers of religion or by the experience of the individual conscience, religion has ever originated an ethical principle. We have seen above that the hypothesis of a super- natural divine revelation is not necessary in order to explain the existence of our ethical principles and practices. We have also seen further that these principles and practices have their origin in general not in man's feeling toward the divine, but in his inter- course with his fellow-creatures. There seems to be no rule of ethical usage among us that does not finally go back to our view of its bearing on the well-being of society. This last is the final standard by which we test all our arguments on moral questions. If we wish to decide on the desirableness of flogging on board ships, we ask whether it maintains discipline better than any other punishment, and how it affects the character of the sailor, it being assumed that the proper development of the individual is an essential element of social progress. In the same way we treat all disciplinary problems — capital punishment, solitary confine- ment, corporal chastisement by parents and teachers : we inquire into the effect on the individual, but the individual as a member of society. We recognize individual rights, but we do not hesitate to sacrifice them to the welfare of the whole. No sympathy with a culprit affects us if we believe that the good of the community requires his punishment. An argument which demonstrates the best social good is considered final. In the prohibition contro- versies the only point really considered by the disputants is, Does prohibition prohibit ? Is war lawful ? The answer is given by appeal to the necessities of national life. But how is it with cases of priestly legislation ? Are they not contributions of religion to ethics ? In all such cases I believe it will be found that the ethical principle involved is one which has already been established by society and is only applied by re- ligion. As an example let us take the institution of taboo, whose usages are so widely spread in civilized as well as uncivilized countries. Taboo sets certain things apart as sacred or as the special property of gods or men, not to be owned or used by others. Obviously an ethical principle enters here, since the use of tabooed objects by the community becomes wrong ; and, as taboo is an essentially religious idea, it may be said that religion has here established a moral rule. But let us see whether this is really the case. The customs of taboo are of two sorts, those which relate to the gods and to persons and places consecrated to their worship, and those which relate to ordinary social inter- course. The reverence required for images of deities, for sacred build- ings and their furniture and ministers, is of course a purely re- ETHICS AND RELIGION. 739 ligious sentiment. Of this nature was the sacredness which attached among the Hebrews to the temple and especially to the holy of holies, which none but a minister of religion might enter ; and to the sin-offering, which only the priests were permitted to eat. Persons devoted in any way to the Deity were debarred from certain things which were supposed to render them impure ; here there was no question of an infringement of a moral law, but only the feeling that contact with or use of certain objects impaired the religious efficiency of the devoted person, probably because such acts and objects were held for some reason to be displeasing to the Deity, or to vitiate the body, or to interfere with the func- tions of a ministrant. In some cases we can see the grounds for these provisions, in other cases they go back to customs of un- known origin. The Jewish Nazarite was forbidden to eat or drink of the products of the vine or to cut his hair ; the first of these injunctions was probably a survival from the old nomadic life, in which the vine was not cultivated (so also in the case of the Rech- abites), the second regarded the hair as a seat of life, and there- fore as a symbol of the divine presence and authority. The Roman flamen dialis enjoyed many privileges as a high representative of a god, but on the other hand was enveloped in an extraordinary mass of restrictions : he could not be out of the city a single night, or sleep out of his own bed three consecutive nights ; and no one else might sleep in his bed. He was forbidden to swear an oath ; to wear any but a plain ring ; to walk along a path covered by vines ; to touch flour, leaven, or a dead body ; to touch or to name a dog, a she-goat, ivy, beans, or raw flesh. When his hair and nails were cut, the clippings and parings were buried beneath a tree whose fruit could be offered to the superior deities. His wife was surrounded by similar restrictions. Evidently some of these were intended to keep the priest faithful to his duties, to secure his presence at the temple. The objects he was forbidden to touch were doubtless held, from some forgotten customs, to be distasteful to the deity (taboo). That there was no real ethical element in the prohibition appears from the fact that other men might do the forbidden things with impunity. We may compare the modern notions in some communities which require clergy- men to wear certain sorts of dress, or insist on their refraining from certain things which are regarded as lawful for other men. A minister of religion offending in these points we regard not as immoral, but rather as improper ; a Roman priest so offending would have been looked on as guilty of impiety toward the deity and toward the state. In undeveloped communities the honors paid to the gods are naturally transferred to chiefs and royal persons supposed to be descended from the gods. We may thus explain the prohibition 74o THE POPULAR SCIENCE MONTHLY. of the use of their names by other men, and the custom would be so far religious; but it would probably be encouraged by the chiefs on governmental grounds, and would in so far be ethical. Even the religious usage probably goes back to the sentiment of respect felt for the chiefs as rulers. A number of taboo customs seem to be probably or possibly social. The prohibition of the use of the flesh of a particular animal or of a whole class of animals as food is of uncertain origin. It is supposed by some to result from the idea of to- tems, each tribe refraining from the flesh of its own totem, but other considerations may have entered in part at least into the usage, and the origin of totemism itself is unknown. The rule among some tribes that women shall not eat human flesh is possi- bly social; it was perhaps intended to guard the character of women. When it is forbidden to touch a dead body or a burial- ground, or a man who has slain an enemy, the idea of pollution thus incurred may be physical, though it may also come from the belief that the dead person is a spirit or inhabited by a spirit. It is possible also that this last may be the ground of the rule that persons dangerously ill should not be touched ; here, however, a physical reason may have been effective. The appropriation or protection of property by taboo depends on ordinary principles of social organization. When a chief declares that a certain object is his head or his hand, and thereby secures it for himself, this is merely using the religious sanction to give authority to what we may suppose to be a natural disposition in chiefs, namely, to appropriate as much of the property of their tribesmen as pos- sible. A private man who declares his field taboo, and thus pro- hibits other men from entering it, is only asserting the right of private property and calling in the aid of religion. It may fairly be said that those taboo usages which are really ethical arise from ideas which have been established by social intercourse. In the case of the sick person, for example, that cer- tain persons are forbidden to touch him is a religious usage, and if the prohibition were universal, it would be fatal to the sick man ; but the helpfulness of those persons who actually tend him comes from the kindly relations engendered by ordinary social inter- course, which overbear the religious prohibition. It does not appear that taboo has ever pronounced any class of actions to be good or bad ; it has only brought particular acts under existing moral categories. Neither it nor any other religious institution has ever in the first instance taught men that it was wrong to steal or right to be kind. So far we have regarded only the content of ethical usage. We now have to ask whether, if religion has received its code from ethics, it has not communicated something in return. It is ETHICS AND RELIGION. 741 a noteworthy fact that many great ethical teachers have been at the same time religious reformers ; such were Zoroaster, Buddha, Jesus, and Mohammed. In other cases, as in the codes of the Egyptian Ptah-hotep and of Socrates, though there is no religious revolution, a religious atmosphere is present. Where religion seems to be lacking, as in the case of Confucius, still it may be said that the ethical system has arisen in a community permeated with religious ideas. From these facts it might be supposed that religion has been the most powerful influence in the world in the elaboration of moral codes. But it must be borne in mind that at a period when religion was bound up with common life much more closely than now, a practical thinker (and such the great religious reformers were) could not separate the two. In Semitic nations not only morals but government also was bound up with religion. Ethics and religion were so intertwined in human de- velopment that, though their origins and laws of growth may have been different, they had come together into a substantial unity. In thus associating itself with ethics, religion supports it by supernatural sanctions. It is a question of serious import, which doubtless now occupies many minds, whether the moral status of society could be maintained without this external aid. It is a question to which no decided answer can be given, because the experiment has never been tried. The probability is that, if the religious element of thought were now abruptly eliminated from our society, the moral life would suffer enormously if it did not perish outright. Such a sudden withdrawal is, however, impossi- ble, and need not enter into our calculations. The elimination of religion, if it can be conceived of as possible, could be effected only by a very gradual process, during which men would be little by little trained under other influences. The vanishing of reli- gion, indeed, out of human life is hardly conceivable ; but we may suppose that the conception of its sanctions may change — the physical-supernatural form of them may give way to the moral. This change has actually begun : a not inconsiderable section of the Christian world now believes that the rewards and punish- ments which attach to well-doing and ill-doing are determined by natural law, whether in the physical or in the moral life. Nor can we see that the effect of this change on the ethical status of society is bad. If the bodily rewards and punishments have van- ished, new and strong ethical motives have been introduced ; there is a deeper sense of personal responsibility, and there are higher ideals. A still more fundamental inquiry is how far the practical ethical life of the world is affected by the belief in future rewards and punishments. But to discuss this point properly would 742 THE POPULAR SCIENCE MONTHLY. ' require a collection of data which has not yet been made. It has been said that men are deterred from wrong-doing much more by the fear of immediate punishment than by the prospect of a retri- bution which seems indefinitely remote.. Such, certainly, appears to a superficial view to be the state of the case ; a keen observer of human life long ago remarked that because sentence against an evil work is not executed speedily, therefore the heart of the sons of men is fully set in them to do evil. But who can read the deeper-lying motives of men ? Who knows what profounder ethical direction is given to life by the constant contemplation of recompense beyond the grave ? The history of human virtue and vice has unfolded itself, almost without exception, in the atmos- phere of this belief. One noted exception there is — the early Semites, the Assyrians, and the Jews prior to B. c. 300, appear to have lived practically without recognition of the future, and it does not seem that their morality was inferior to that of other nations ; we ourselves indeed must acknowledge that, so far as our practical life is concerned, we have something to learn from the codes of the prophets and the law. But it must be said, on the other hand, that the Jews of that time had a powerful ethical stimulus which is wanting in our time — namely, a vivid belief in the immediateness of divine interventions in human life, An ex- periment of a morality supported only by human sanctions has never been tried in modern times on a large scale. Nor can it be doubted that the belief in future retribution exerts a powerful influence on men's lives. Strictly speaking, however, this belief does not belong to the domain of religion. Its precise origin is doubtful, but it has arisen from man's reflection on his own life, and not on his relation to the Deity. Its relations with both religion and ethics are close, but it can 'not properly be said to represent an influence of the former on the latter. It appears, then, that the real substance of man's ethical code has not been affected by religion. The belief in supernatural re- wards and punishments, though it influences men's conduct, is not a moral force ; it has no power to change the heart. The true salutary influence of religion on human life is found in the crea- tion of divine ideals to be loved and imitated. Such an ideal is the embodiment of man's own highest ethical conceptions. Vi- talized into a person, ethical perfectness acquires an independent power, attracting and stimulating us, lifting us up above the ordi- nary low level of our lives, inspiring us by presenting a goal to be reached, and encouraging us with the hope of divine aid. The standard of human achievement is expressed in the exhortation of Jesus to men to be perfect as God is perfect, and the proper emotional attitude in the Old Testament declaration that men are to love God with all the heart. Such a love toward God ETHICS AND RELIGION. 743 as a perfect being implies the love of right in man's soul ; but this love may exist in incomplete or feeble form, and may be heightened and developed by constant contemplation of ideal goodness ; it is still further aided by the sentiment of gratitude in response to benefits believed to have been received from the hand of God. The effect of such ideals is both to ennoble individual charac- ter and to elevate the moral standard of the community. A con- ception of perfectness formed by the best minds always goes be- yond the general practice, and calls into being principles of action which gradually make their way from the few to the many. A gradual reorganization of society is thus effected ; social inter- course is based on these enlarged ethical views, habits spring up in accordance with them, they create new grooves for men's sym- pathies and interests, so that it becomes, as a rule, easier to act with than against them, easier in general to do right than to do wrong. It is impossible, however, to define the influence of the ideal precisely, to separate it from the general effects of social life. Take, for example, the principles of forgiveness and revenge as they exist among us. The recognized religious ideals in all parts of this country inculcate the duty of forgiveness of injuries, and yet the practice varies greatly in different regions. The differ- ence of custom appears to depend chiefly on difference of social organization. In those communities which are semi-feudal in character, where there is comparatively little social organization, and individuality of action has been cultivated, the habit of re- venge for personal injuries is more common ; while in those com- munities in which commercial interests are stronger, and social combinations firmer and more numerous, personal vengeance is rarer, and the appeal to society and law more frequent. Whether there is a corresponding difference in the temper of the soul may be a question ; yet it is probable that the constant habit of refrain- ing from private retaliation induces a more peaceful and sel*f- restraining attitude of heart. The effect of the religious ideal is, however, seen in individuals in all Christian communities, who practice forgiveness out of loyalty and love to the divine law- giver. And it is impossible to say how far this ideal has every- where affected the feeling of men through the example of those who have manifested obedience to the religious law of for- giveness. There are, of course, ethical as well as religious ideals, and these have had their due effect. The moral progress of men has been effected by the combination of the two great factors, the organization of society and ethical-religious ideals. Every step taken toward binding men closer together in social life, and every announcement and practical exhibition of a supereminent ethical 744 THE POPULAR SCIENCE MONTHLY. principle is an element of advance toward social perfection. The progress may be largely external, and change of heart does not always accompany conformity to rule ; nevertheless, long-contin- ued habit is almost sure to produce change in men's conception of life. DARWIN ON THE FUEGIANS AND PATAGONIANS.* HAVING now finished with Patagonia and the Falkland Isl- ands, I will describe our first arrival in Tierra del Fuego. A little after noon we doubled Cape St. Diego and entered the famous Strait of Le Maire. We kept close to the Fuegian shore, but the outline of the rugged, inhospitable Staten-land was visible amid the clouds. In the afternoon we anchored in the Bay of Good Success. While entering we were saluted in a manner be- coming the inhabitants of this savage land. A group of Fue- gians, partly concealed by the entangled forest, were perched on a wild point overhanging the sea ; and, as we passed by, they sprang up and waving their tattered cloaks sent forth a loud and sono- rous shout. The savages followed the ship, and just before dark we saw their fire, and again heard their wild cry. The harbor consists of a fine piece of water half surrounded by low, rounded mountains of clay-slate, which are covered to the water's edge by one dense, gloomy forest. A single glance at the landscape was sufficient to show me how widely different it was from anything I had ever beheld. At night it blew a gale of wind, and heavy squalls from the mountains swept past us. It would have been a bad time out at sea, and we, as well as others, may call this Good Success Bay. In the morning the captain sent a party to communicate with the Fuegians. When we came within hail, one of the four natives who were present advanced to receive us, and began to shout most vehemently, wishing to direct us where to land. When we were on shore the party looked rather alarmed, but continued talking and making gestures with great rapidity. It was without excep- tion the most curious and interesting spectacle I ever beheld : I could not have believed how wide was the difference between sav- age and civilized man : it is greater than between a wild and do- mesticated animal, inasmuch as in man there is a greater power of improvement. The chief spokesman was old, and appeared to be the head of the family ; the three others were powerful young men, about six feet high. The women and children had been sent * From advance sheets of a new edition, illustrated by R. T. Pritehett, of Darwin's " Journal of Researches " made during the voyage round the world of H. M. S. Beagle, in preparation by D. Appleton & Co. DARWIN ON THE FUEGIANS AND PATAGONIANS. 745 away. These Fuegians are a very different race from the stunt- ed, miserable wretches farther westward ; and they seem closely allied to the famous Patagonians of the Strait of Magellan. Their only garment consists of a mantle made of guanaco- skin, with the wool outside ; this they wear just thrown over their shoulders, leaving their persons as often exposed as covered. • Their skin is of a dirty coppery-red color. The old man had a fillet of white feathers tied round his head, which partly confined his black, coarse, and entangled hair. His face was crossed by two broad transverse bars : one, painted bright red, reached from ear to ear and included the upper lip ; the other, white like chalk, extended above and par- allel to the first, so that even his eyelids were thus colored. The other two men were ornamented by streaks of black powder made of charcoal. The party altogether closely resembled the devils which come on the stage in plays like Der Freischiitz. Their very attitudes were abject, and the expression of their coun- tenances distrustful, surprised, and startled. After we had presented them with some scarlet cloth, which they immediately tied round their necks, they became good friends. This was shown by the old man patting our breasts, and making a chuckling kind of noise, as people do when feeding chickens. I walked with the old man, and this demon- stration of friendship was repeated several times ; it was concluded by three hard slaps, which were given me on the breast and back at the same time. He then bared his bosom for me to return the compliment, which being done, he seemed highly pleased. The language of these people, according Fig. 1.— Fcegian Basket and Bone Weapons. 746 THE POPULAR SCIENCE MONTHLY. to our notions, scarcely deserves to be called articulate. Captain Cook has compared it to a man clearing his throat, but certainly no European ever cleared his throat with so many hoarse, guttural, and clicking sounds. They are excellent mimics : as often as we coughed or yawned, or made any odd motion, they immediately imitated us. Some of our party began to squint and look awry ; but one of the young Fuegians (whose whole face was painted black, excepting a white band across his eyes) succeeded in making far more hide- ous grimaces. They could repeat with perfect correctness each word in any sentence we addressed them, and they remem- bered such words for some time. Yet we Europeans all know how difficult it is to distinguish apart the sounds in a foreign language. Which of us, for instance, could follow an American Indian through a sentence of more than three words ? All savages ap- pear to possess, to an uncommon degree, this power of mimicry. I was told, almost in the same words, of the same ludicrous habit among the Caff res ; the Australians, likewise, have long been noto- rious for being able to imitate and describe the gait of any man, so that he may be recognized. How can this faculty be explained ? Is it a consequence of the more practiced habits of perception and keener senses, common to all men in a savage state, as compared with those long civilized ? When a song was struck up by our party, I thought the Fue- gians would have fallen down with astonishment. With equal surprise they viewed our dancing ; but one of the young men, when asked, had no objection to a little waltzing. Little accus- tomed to Europeans as they appeared to be, yet they knew and dreaded our firearms ; nothing would tempt them to take a gun in their hands. They begged for knives, calling them by the Span- ish word cuchilla. They explained also what they wanted, by acting as if they had a piece of blubber in their mouths, and then pretending to cut instead of tear it. It was as easy to please as it was difficult to satisfy these sav- ages. Young and old, men and children, never ceased repeating the word yammer schooner , which means " give me." After pointing to almost every object, one after the other, even to the buttons on our coats, and saying their favorite word in as many intonations as possible, they would then use it in a neuter sense, and vacantly repeat yammer schooner. After yammerschooher- ing for any article very eagerly, they would by a simple artifice point to their young women or little children, as much as to say, 'If you will not give it me, surely you will to such as these." There is one vegetable production deserving notice from its im- portance as an article of food to the Fuegians. It is a globular, bright-yellow fungus, which grows in vast numbers on the beech- DARWIN ON THE FUEGIANS AND PATAGONIANS. 747 trees. When young it is elastic and turgid, with a smooth sur- face ; but when mature it shrinks, becomes tougher, and has its entire surface deeply pitted or honeycombed, as represented in the accompanying woodcut. This fungus belongs to a new and curious genus. I found a second species on another species of beech in Chili ; and Dr. Hooker informs me that just lately a third species has been discovered on a third species of beech in Van Diemen's Land. How sin- gular is this relationship between parasitical fungi and the trees on which they grow, in distant parts of the world ! In Tierra del Fuego the fungus in its tough and mature state is collected in large quantities by the women and children, and is eaten uncooked. It has a mucilaginous, slightly sweet taste, with a faint smell like that of a mushroom. With the exception of a few berries, chiefly of a dwarf arbutus, the natives eat no vegetable food besides this fungus. In New Zealand, before the introduction of the potato, the roots of the fern were largely consumed ; at the present time, I believe, Tierra del Fuego is the only country in the world where a cryptogamic plant affords a staple article of food. Fig. 2. -Ctttakia Dar- WINII. Mr Fig. 3— Patagonians from Cape Gregory. In the end of May, 1834, we entered for the second time the eastern mouth of the Strait of Magellan. The country on both sides of this part of the strait consists of nearly level plains, like those of Patagonia. Cape Negro, a little within the second Nar- rows, may be considered as the point where the land begins to 748 THE POPULAR SCIENCE MONTHLY. assume the marked features of Tierra del Fuego. On the east coast, south of the strait, broken, park-like scenery in a like man- ner connects these two countries, which are opposed to each other in almost every feature. It is truly surprising to find in a space of twenty miles such a change in the landscape. If we take a rather greater distance, as between Port Famine and Gregory Bay, that is about sixty miles, the difference is still more wonder- ful. At the former place we have rounded mountains concealed by impervious forests, which are drenched with the rain brought by an endless succession of gales ; while at Cape Gregory there is a clear and bright blue sky over the dry and sterile plains. The atmospheric currents, although rapid, turbulent, and unconfined by any apparent limits, yet seem to fol- low, like a river in its bed, a regularly determined course. During our previous visit (in January), we had an interview at Cape Gregory with the famous so-called gigantic Patagonians, who gave us a cordial reception. Their height appears greater than it really is, from their large guanaco mantles, their long, flowing hair, and general figure ; on an average their height is about six feet, with some men taller and only a few shorter ; and the women are also tall ; altogether, they are certainly the tallest race which we anywhere saw. In features they strikingly resemble the more north- ern Indians whom I saw with Rosas, but they have a wilder and more formidable appearance : their faces were much painted with red and black, and one man was ringed and dotted with white like a Fuegian. Captain Fitz Roy offered to take any three of them on board, and all seemed determined to be of the three. It was long before we could clear the boat ; at last we got on board with our three giants, who dined with the captain, and behaved quite like gentlemen, helping themselves with knives, forks, and spoons: nothing was so much relished as sugar. This tribe has had so much communication with sealers and whalers that most of the men can speak a little English and Span- fig. 4. -PATA- ish ; and they are half civilized, and proportionally de- gonian bolas. moralized. The next morning a large party went on shore, to barter for skins and ostrich-feathers ; firearms being refused, to- bacco was in greatest request, far more so than axes or tools. The whole population of the toldos, men, women, and children, were ar- ranged on a bank. It was an amusing scene, and it was impossible DARWIN ON THE FUEGIANS AND PATAGONIANS. 749 not to like the so-called giants, they were so thoroughly good-hu- mored and unsuspecting ; they asked us to come again. They seem to like to have Europeans to live with them ; and old Maria, an im- portant woman in the tribe, once begged Mr. Low to leave any one of his sailors with them. They spend the greater part of the year here ; but in summer they hunt along the foot of the Cordillera ; sometimes they travel as far as the Rio Negro, seven hundred and fifty miles to the north. They are well stocked with horses, each man having, according to Mr. Low, six or seven, and all the Fig. 5. — Patagonian Spurs and Pipe. women, and even children, their one own horse. In the time of Sarmiento (1580) these Indians had bows and arrows, now long since disused ; they then also possessed some horses. This is a very curious fact, showing the extraordinarily rapid multiplica- tion of horses in South America. The horse was first landed at Buenos Ayres in 1537, and the colony being then for a time de- serted, the horse ran wild ; in 1580, only forty -three years after- ward, we hear of them at the Strait of Magellan ! Mr. Low in- forms me that a neighboring tribe of foot-Indians is now chang- ing into horse-Indians ; the tribe at Gregory Bay giving them their worn-out horses, and sending in winter a few of their best skilled men to hunt for them. June 1st. — We anchored in the fine bay of Port Famine. It was now the beginning of winter, and I never saw a more cheer- less prospect ; the dusky woods, piebald with snow, could be only seen indistinctly through a drizzling, hazy atmosphere. We were, however, lucky in getting two fine days. On one of these, Mount Sarmiento, a distant mountain six thousand eight hundred feet high, presented a very notable spectacle. I was frequently sur- prised, in the scenery of Tierra del Fuego, at the little apparent elevation of mountains really lofty. I suspect it is owing to a cause which would not at first be imagined, namely, that the 75° THE POPULAR SCIENCE MONTHLY. whole mass, from the summit to the water's edge, is generally in full view. I remember having seen a mountain, first from the Beagle Channel, where the whole sweep from the summit to the base was full in view, and then from Ponsonby Sound across sev- eral successive ridges ; and it was curious to observe in the latter case, as each fresh, ridge afforded fresh means of judging of the distance, how the mountain rose in height. IS EDUCATION OPPOSED TO MOTHERHOOD? 751 IS EDUCATION OPPOSED TO MOTHERHOOD ? By ALICE B. TWEEDY. IF, as Max Muller asserts, the first duty of honest philosophers is definition, there can be no doubt that in following it many- clouds of discussion may be swept away. Definitions are contin- ually assumed, and we clothe our creeds in wordy obscurity that totally hides their nature. No subject suffers more from this error than the woman question. If debated words were rigidly defined, and results placed barely before us, many sentimental arguments would fail in foundation. In " Plain Words on the Woman Question," * Mr. Grant Allen discusses a topic which, he thinks, is " too much overlooked by modern lady writers." It is the continuation of the human race. Intrenched behind population and marriage statistics, he opens fire upon feminine reformers from a quarter where they have made little defense. His text is — if a race will continue, it must reproduce itself. His argument may be briefly given as follows : I. Marriages are decreasing in England and America. II. Women of the cultivated classes are becoming unfitted for motherhood. III. The movement which demands the independence and higher education of women is responsible for this — it creates a "spiritless epicene automaton" and the "self-supporting spinster." IV. The emancipation of women, especially from Mrs. Grundy, is desirable ; but it must not conflict with the existence of mothers who are necessary to the race. Mr. Allen states the needful conditions of a stationary popula- tion in this manner : A father and mother are exactly represented in another generation by two children, a boy and a girl. But, in order that two may attain maturity, four \ must be born ; so that either every woman must have four children, or those who do marry must have more than four to make up the requisite num- ber. From this he deduces: " The best ordered community will be one where as large a proportion of women as possible marry. Where many marriages and small families are the rule, the chil- dren will on the average be born healthier, be better fed, and be launched more fairly on the world in the end." After clearly stating and carefully explaining these indisputa- ble facts, Mr. Allen startles us by acknowledging that " it may be brutal and unmanly to admit or insist upon them," as he has been * " Popular Science Monthly," December, 1889. f This number is based upon the present proportion of children who become healthy adults, statistics which ought to be materially altered for the better. 75 2 THE POPULAR SCIENCE MONTHLY. " often told it is by maiden ladies " ! There is but one intelligent attitude concerning them — are they true or false ? Granting, then, that these conditions are truthfully represented, what can be said to the argument which Mr. Allen founds upon them ? I. Marriages are decreasing in many civilized countries. There are local causes for this tendency among men, but the principal and prevailing one with women is that they are passing from the rule of force to a state of freedom, and use their newly found lib- erty to reject what seems to hamper and handicap them. They are emerging from the condition in which marriage is consequent upon physical or social constraint, and they have not generally arrived at the point where it is for them the result of deliberate choice or response to natural instinct. In China, India, Persia, and Arabia, where marriages are still controlled by force, the number would be diminished at once, without the influence of higher education or industrial training, were the women allowed simple freedom of choice.* This decrease would not indicate "the dulling of feminine instinct," but the vitality of it — since marriages are made there in defiance of natural selection, and represent the worst condition of servitude. In more civilized states the popularity of marriage does not depend wholly upon the way in which women regard it, but upon the way in which it is treated by men. The laws of some countries render it easier for a man to live illegitimately with a woman than to marry her ; f true marriage is discouraged by social usage and dishon- ored by false philosophy. Few thoughtful minds will deny that the customs which render it difficult for a young man to marry, which send him hither and thither to gain a fortune, succeed in a profession, or dissipate his strength, when he should be choosing his sweetheart, are harmful, and divert men " from the true prob- lem of their sex to fix it on side issues of comparative unimpor- tance." Boys, as well as girls, should be taught that the full meaning of human life is missed unless they deserve and find a fitting mate. Authors who represent wifehood and maternity f as onerous and unattractive, however necessary, or who surround illicit and in- * It is related that in 1878 eight young girls living near Canton, having been betrothed, arrayed themselves one evening in fine attire, bound themselves together, and plunged into the river to avoid marriage. f In Germany, where marriage is forbidden the younger soldiers, the birth statistics are disadvantageous to the state. \ Some English conservatives discourse on these topics in a strain wholly abhorrent to healthy women. They write of "the inexorable laiv from which, however distasteful, a woman can not escape " ; " the stem law that makes women wives and mothers." One would imagine from them that marriage and motherhood made a yawning grave of hope and aspi- ration. Normal women, who have passed through these experiences, use no woful tones in description. IS EDUCATION OPPOSED TO MOTHERHOOD? 753 complete love with superficial glamour, are open to the charge of depreciating marriage. Guests are not tempted to a banquet by- fear of starvation, nor are men attracted toward matrimony for the interests of the race. Instead of showing that marriage offers the greatest possibility of happiness, it is often described by men as an unintellectual, slavish, and pitiable condition. Few epi- thalamia are sung by the generation which asks, " Is marriage a failure ? " and rare is the poet who writes : " Clear as amber, fine as musk, Is life to those who, pilgrim- wise, Move hand in hand from dawn to dusk." II. Mr. Allen seems to regard as evidence that women " are becoming unfitted for motherhood" the fact that they do not glory in their femininity, and charges also that women reformers speak and write " as though it were desirable that the mass of women should remain unmarried forever/' Worse even than this, he asserts : " At the present moment a great majority of the ablest women are wholly dissatisfied with their own position as women, and with the position imposed by the facts of the case upon women generally ; this as the direct result of their false edu- cation." Here are two ideas badly entangled for want of defini- tion— the natural and the artificial position of women. Mr. Allen gives us on the following page his opinion of " the position " (arti- ficial) of women in language strong enough for the most blatant reformer. " The position of women was not a position which could bear the test of nineteenth-century scrutiny ; . . . their rela- tion to the family, to their husbands, their children, their friends, their property, was simply insupportable." (Does he demand of these ablest women that they should be satisfied with a position he calls " insupportable " ?) But, let him not be distressed because woman does not openly " glory " in her natural position of woman- hood. There is no failure of healthy instinct here, but a natural feminine divergence from the masculine feeling. The differentia- tion of the sexes is a subject upon which we have no adequate data. We might as well try to surmise the habits of the wild cat from the domesticated pussy, as to speculate upon the essential qualities of free womanhood. But, so far as woman's physical constitution indicates anything, it points toward greater reserve on her part than is exhibited by man. This corresponds with the almost universal inclination of women to be more modest than men.* Therefore, though a woman may prefer her own sex and be proud of her privileges as woman, she will not voluntarily go about " glorifying " her womanhood. If Mr. Allen should meet a young woman who announced herself a candidate for mother- * A few savage tribes form exceptions to this rule. vol. xxxvi. — 48 754 THE POPULAR SCIENCE MONTHLY. hood, it is doubtful" whether he would approve of her, although she embodied his theory.* Here, also, Mr. Alleu misinterprets the women reformers of England. He states that they " openly refuse and despise mar- riage." Some may ; some write very bitterly of men. But this refusal is for themselves, or for the class to which they belong — reformers. In this they do not differ from a large number of religious or political enthusiasts of both sexes, in every age, who claim that their " cause " is superior to individual rights or duties. "Who is the woman in England who maintains such doctrine for the majority of her sex ? One of the ablest advocates for women, Emily Pfeiffer,f writes to her countrymen : " You do not well to rest your hope On natures of a narrower scope, And leave the souls which, like your own, Aspire, to find their way alone — To go down childless to their graves, The while you get your sons of slaves." Though men have greatly outgrown tyranny of thought and action, there is still alive much masculine arrogance. "With many it is entirely unconscious ; it probably is so with Mr. Allen when he calls a literary or scientific education " mannish." I do not know of any purely mannish training except that received by the monks of La Trappe, and that which fits men to be soldiers, sail- ors, blacksmiths, or workmen whose physical force is a necessity to their calling. A college or university education, although in past years given exclusively to men, was never supposed to fit them for any essentially masculine occupation, not even to become the fathers of the future race. It was preliminary to a profes- sional or literary career, and intended to develop the powers of mind. And mind — emphasize as we will the physical differences of the body that goes with it — has no discoverable gender. The lavish way in which the epithet of " masculine " or " feminine " has been applied to particular minds is utterly destructive of pre- cision of thought. Vigorous minds are called masculine and those of the namby-pamby, sentimental sort are dubbed feminine. This classification may be historically justifiable by the slight appearance women have made in the literary and scientific world, * In college days I knew a young lady medical student who illustrated this doctrine. She openly proclaimed that she studied mediciue for the purpose of fittiDg herself to be- come a wife and mother. She enlarged her waist, wore most ungraceful garments, broached her pet idea on social occasions, and was the bete noire of her companions. Perhaps she was Mr. Allen's ideal of an emancipated woman. Her fellow-students thought she had missed the inheritance of womanly instinct, or that some secondary male characteristic had cropped out in her.

IS EDUCATION OPPOSED TO MOTHERHOOD? 755 but there have been clear-headed women enough in all antiquity, and there are too many well-developed minds among them to-day, not to make them resent further tricking out with masculine trappings. The wise old Greeks saw fit to personify mind in a woman ; the moderns seem to be afraid of such a result. If education must be specialized, and women should be fitted to become wise mothers, then, in all fairness, men should be trained to become intelligent fathers. Their lack in this respect is as palpable to any just mind as the failure of women in moth- erhood. That there should be fathers, and good fathers, is no less important, from a utilitarian standpoint, than that there should be good mothers. Indeed, it may be questioned whether there are not annually more children lost to the world through the wickedness and ignorance of male parents * than would be gained by the conversion of all " self-supporting spinsters " into model matrons. It is not necessary to enter into detail here, but appall- ing statistics are easily obtainable. Until no foundling hospital, no abandoned family exists, it is ungenerous to reproach woman with evading or " shirking " her natural duties. Postponement of marriage by men results in another not inconsiderable evil, false marriage f of many young women. Nature often revenges herself here by a lack of mothers. The wiser plan would be to follow the teaching of Nature and not dissociate the sexes, par- ticularly during impressionable years. In study, work, or society, do not bar them from each other ; then they will not form the erroneous notions that taint maturity. Let them be " human, instead of half -human." III. The most evident good of education to woman, aside from the discipline of mind and development of power, is in its teach- ing observation of nature and the intelligent use rather than the repression of any instinct or force. Those who assert that these influences " unsex " woman, render her " unwomanly/' should ex- plain what is meant. She may lose some of the characteristics that have distinguished her in the past, but while analytic or radical minds call these characteristics local and temporary, con- servatives cling to them as part of essential womanhood. It may be observed that, although Mr. Allen holds fast to the term of " radical," he agrees with our dear old great-grandmothers in this apprehension that education % and independence unfit women to become mothers. To these timid souls may be recommended a * Meaning the sex as a whole.

The traditional idea that womanhood can be modified in some occult t way by occupation, training, or environment, is wholly unscientific and baneful ; for it undoubtedly serves to nurse in many a woman that " slavish- ness of soul " which Mr. Allen, as a true well-wisher of woman, deplores. Physical condition, then, is the constant coefficient in the problem. Anything injurious to the health of either man or woman incapacitates each just so much for the fullest require- ment of life. Mr. Allen claims that the result of the higher education in England and America has been to convert woman into " a dulled and spiritless epicene automaton." Now, this peculiar product, which I take to mean the opposite of a healthy woman, must be wholly within the reach of statistics, else she, or it, is a fabulous affair. In England it is possible she may exist, but the best avail- able statistics of Girton, Newnham, and Cheltenham prove that she is not typical. The following testimony in regard to women students is given : \ " I have known intimately Girton and Newnham Colleges and what is now the women's department of Owens College, Manches- ter. . . . Were an impression to get abroad that a thorough school and college education is injurious to tolerably healthy women, it would be as mistaken as it would be unfortunate " (Miss Bulley). " My unqualified testimony is, that the intellectual quickening resulting from advanced education is of great benefit to their phys- ical condition " (Miss Mackillip, Londonderry Collegiate School). " I have been head of this college for more than twenty-eight years. . . . We have kept the minutest possible statistics # — these show that girls, working under proper conditions, are exception- ally healthy " (Miss Beale, Cheltenham College). Mr. Fitch, inspector of training schools, testifies : " There are in England twenty-six training colleges for schoolmistresses, containing in all eighteen hundred resident students. It is my duty, on behalf of the Government, to make an annual visit to these institutions, and I have seen every one of them during the last twelve months. ... It is the uniform opinion of the medical * The average notion of manliness or womanliness is very fluctuating.

In America, the dulled automaton is not discoverable ; indeed, the records are so much in favor of a healthier class than the average of women that physicians who have hastily committed themselves to an opposite opinion say, upon examination, that they " utterly distrust the statistics " ! * The necessary amount of this distrust, and the direction in which it is exercised, may be estimated by citing the authorities for the health of women stu- dents: Secretary of the Society of Associated Alumnse of Ameri- can Colleges,! seven hundred and five alumnse who report person- ally ; Committee of Education, 1883-84, Washington ; Addresses of President Angell, of Michigan University ; ex-President White, of Cornell; and President Horace Davis, of the University of California. But, it may be asked, " Are doubting physicians not justified at all — are there no women students who break down % or die ? " There are such cases of overstrain or feeble constitution which find their parallel among men, but the percentage among women is so small that it leaves the health average still above the gener- ality of women. But, urges Mr. Allen, there is "the self-supporting spinster"; " almost every woman should marry " ; and she is " a deplorable accident." Now, it is possible that while I may deem her admi- rable, another may consider her " deplorable " — it is a matter of taste merely. But, that she is not an " accident," rather an eternal verity, stands confessed in Mr. Allen's " almost." Unless, indeed, the entire community should be paired off — which is not desir- able for economic reasons — spinsters and bachelors will continue to exist. It does not materially affect the issues of the race whether they are dependent or independent,* and we may fear- lessly praise in them the qualities which please us most. If the condition of "self-supporting spinsterhood " is more attractive than the condition of wifehood, there is menace for the future. * Dr. Weir Mitchell, "Wear and Tear," p. 151. f Report published at Boston, May, 1885. \ Rumors of this kind are sometimes too readily circulated.

When she found she couldn't graduate, she went to Vassar as a special student, because, she said, ' it was so far away no one would know whether she stood high or not, and she didn't intend to study her eyes out.' " The doctor's countenance fell. One victim of "higher education" was crossed off the score. * It is desirable that young women should support themselves for these reasons : (1) that they may be free to marry ; (2) in case they fail of marriage ; and (3) beeause sickness or accident to the husband may render a wife's support valuable. 75 8 THE POPULAR SCIENCE MONTHLY. It would be alarming, if we could believe with. Mr. Allen in any- thing so unflattering to masculine endeavor ; but, unfortunately, there are no statistics to prove whether this is due to dulled femi- nine instinct, or to the failure of man to make love at the right time. In the interim, from collateral evidence, the latter cause appears more trustworthy. IV. If freedom from Mrs. Grundy is desirable, it is patent that education and independence are gradually liberating woman. The counter-charge is often made that the educated woman is too regardless of that favored deity. From a biological point of view, Mr. Allen endows four years of college training with enormous potentiality. In this he evi- dently follows the eminent leader, Mr. Herbert Spencer, who asserts that the infertility of " upper-class girls " in England is due to " overtaxing of their brains " ! * Whether the majority of English " upper-class girls " are educated to that extreme point, and whether the question is not begged in the use of the word "overtaxation," may be left to the reader. It is strange that powerful heredity and palpable causes of race deterioration should be ignored by physiologists f in order to throw the onus of this accusation upon mental culture. Insurance tables are made out more scientifically than this forecast of a girl's future. If in education, or in the industrial independence of women, there existed any tendency toward infertility, it would be barely dis- coverable in our generation, little more so in the next, and possi- bly in the third generation something might be ascertained from careful statistics following Mr. Galton's method. Nature does not retrograde so rapidly. There is nothing to warrant the as- sumption that four years of altered food, training, or environ- ment, not interfering with good physical condition, could obliter- ate an instinct or function. Investigation corroborates this. Even in England, we learn that infertility and higher education are not synonymous terms. A teacher of wide experience states : \ " I know several families of children whose mothers were among the pioneers of the movement now so savagely attacked. . . . Among my friends, not a few sturdy, handsome children, whose mothers underwent severe study in their earlier days. One of these was a lady who, with one other, was the first woman to take the classical tripos, and whose degree was not beaten, I think, for ten years."

IS EDUCATION OPPOSED TO MOTHERHOOD? 759 had children, the exceptional record of good health among these children, and their low death-rate, are strong evidences that the powers of motherhood have not suffered from college work."* In addition, the writer's mite of testimony may be offered. In the schools which she has attended,! the majority of earnest stu- dents were in uniformly good health ; a minority were delicate before beginning study. The most frequent examples of ill health were found among those who made a pretense of study and eagerly pursued social excitements. Subsequent effect upon the health may be judged when it is found that twelve years after graduation one young woman, ranking at the head of her class, is the mother of six vigorous children ; two others, earnest students, have each a family of five, and a number of others have four children. No correspondence has been held with married class- mates living at a distance. These mentioned are personally known to be mothers in the fullest sense, and constitute striking contradictions to the claim that education has an injurious effect upon woman. "But," it may be objected, "these are exception- ally healthy women." Undoubtedly, but if the training has any influence at all, it should make them fall slightly below the stand- ard of the preceding generation, whereas, in several instances, they improved upon the record of their mothers, not only in gen- eral health, but in the condition and size of their families. If, now, we review the discussion to this point, it may be summed up as follows : I. Decrease of marriage results from a transition state in the condition of women, also from unjust laws and false social cus- toms which discourage matrimony. II. Able women generally are not dissatisfied with woman- hood, and do not advocate celibacy. It is not evident that women of any class are becoming unfitted for motherhood, but women of the " cultivated classes " are not the best possible mothers. Inde- pendent and highly educated women are only a fraction among these, and can not be substituted for the whole. III. The higher education of woman teaches her reverence for Nature ; the development and control, not the suppression of natural instinct, therefore tends to make her the best wife and mother. The "spiritless epicene automaton" is mythical. The spinster is an eternal verity. The woman movement has not created her, but changed her condition from dependence to self-support. IV. The education and independence of women is a step in emancipation even from Mrs. Grundy, but it can not be made responsible for the present infertility among women, for these reasons : * Report of "Health Committee, Association Coliegiate Alumnse," Annie G. Howes, 1885. f Four schools for girls, one college for women, two universities for men and women. 76o THE POPULAR SCIENCE MONTHLY. First. It is too recent in effect, having barely reached the sec- ond generation. Second. There are more potent causes — heredity, race deterioration, and false marriage. Third. It actually pro- duces healthy wives and mothers in the fullest sense. There is no denial of the fact that too large a percentage of educated women,* as well as of the cultivated classes generally, remain unmarried. However, it has been shown in regard to the former, that " dulled instinct " is not a tenable cause. Some have attributed it more wisely to increased " nicety of choice." This may prove beneficial in the end, when man shall have become a more importunate suitor. Women can no longer be coerced into marriage, nor will they marry from a sense of duty to humanity. But for these reasons there need be no fear that the race will perish. There is as much prospect that roses will refuse to bloom in June as that women will ever become invincible to love. This force, and this alone, can make of them light-hearted mothers in place of the weary wrecks whose perverted motherhood has been anything but a boon to humanity. As long as it is taught that motherhood oppresses woman physically and restricts her intellectually, so long the average woman may dread or rebel against it. "When she studies it in all its conditioning, she finds it does not impose such a fate upon her. She learns to discriminate between the ordering of Nature and the blunders of mankind, and recognizes that nor- mal physical development can not be antagonistic to mental growth. If, as is known among the lower forms of life, there should be such evil fate in store for women as parthenogenesis or poly- embryony, or any entire change of function or structure, it would be quite useless to rebel. Even such highly imaginary metamor- phosis would not imply extinction of species. The causes of this calamity have not been fathomed by Darwin nor Weissman ; and, if such disintegrating forces were at work among us, who would be wise enough to recognize them ? Study of nature leads us to believe that, if the individual be free and supplied with the means of life, there is great probability of the survival of his kind. However, we have seen that the hu- man race decreases under artificial conditioning, and, if we are concerned lest man should become extinct, let us strive to live simply, naturally ; neither separate nor antagonize the sexes ; then there may be more need of Mr. Malthus than of any pessi- mistic prophecy on the danger of developing a woman's mind. * Highly educated women are yet a minority among women of the so-called " cultivated classes," and are better ranked with working women, since they agree with them more nearly in habits of life. ON THE NATURAL INEQUALITY OF MEN 761 ON THE NATURAL INEQUALITY OF MEN. By Prof. T. H. HUXLEY, F. K. S. THE political speculations set forth in Rousseau's "Discours sur l'origine de l'ine'galite' parmi les hommes," and in the more noted essay, " Du Contrat Social," which were published, the former in 1754 and the latter eight years later, are, for the most part, if not wholly, founded upon conceptions with the origi- nation of which he had nothing to do. The political, like the religious, revolutionary movement of the eighteenth century in France came from England. Hobbes, primarily, and Locke, sec- ondarily (Rousseau was acquainted with the writings of both), supplied every notion of fundamental importance which is to be found in the works which I have mentioned. But the skill of a master of the literary art and the fervor of a prophet combined to embellish and intensify the new presentation of old specula- tions ; which had the further good fortune to address itself to a public as ripe and ready as Balak himself to accept the revelations of any seer whose prophecies were to its mind. Missionaries, whether of philosophy or of religion, rarely make rapid way, unless their preachings fall in with the prepossessions of the multitude of shallow thinkers, or can be made to serve as a stalking-horse for the promotion of the practical aims of the still larger multitude, who do not profess to think much, but are quite certain they want a great deal. Rousseau's writings are so admi- rably adapted to touch both these classes that the effect they produced, especially in France, is easily intelligible. For, in the middle of the eighteenth century, French society (not perhaps so different as may be imagined from other societies before and since) presented two large groups of people who troubled them- selves about politics — in any sense other than that of personal or party intrigue. There was an upper stratum of luxurious idlers, jealously excluded from political action and consequently ignorant of practical affairs, with no solid knowledge or firm principles of any sort ; but, on the other hand, open-minded to every novelty which could be apprehended without too much trouble, and exqui- sitely appreciative of close deductive reasoning and clear expo- sition. Such a public naturally welcomed Rousseau's brilliant developments of plausible first principles by the help of that a priori method which saves so much troublesome investigation.* * In his famous work on " Ancient Law " the late Sir Henry Maine has remarked, with great justice, that Rousseau's philosophy " still possesses singular fascination for the looser thinkers of every country " ; that " it helped most powerfully to bring about the grosser disappointments of which the first French Revolution was fertile," and that "it gave birth, or intense stimulus, to the vices of mental habit all but universal at the time, disdain of 76z THE POPULAR SCIENCE MONTHLY. It just suited the " philosophes," male and female, interchanging their airy epigrams in salons, which had about as much likeness to the Academy or to the Stoa, as the " philosophes " had to the philosophers of antiquity. I do not forget the existence of men of the type of Montesquieu or D'Argenson in the France of the eighteenth century, when I take this as a fair representation of the enlightened public of that day. The unenlightened public, on the other hand, the people who were morally and physically debased by sheer hunger; or those, not so far dulled or infuriated by absolute want, who yet were maddened by the wrongs of every description inflicted upon them by a political system which, so far as its proper object, the welfare of the people, was concerned, was effete and powerless ; the subjects of a government smitten with paralysis for every- thing but the working of iniquity and the generation of scandals ; these naturally hailed with rapture the appearance of the teacher who clothed passion in the garb of philosophy ; and preached the sweeping away of injustice by the perpetration of further injus- tice, as if it were nothing but the conversion of sound theory into practice. It is true that any one who has looked below the surface * will hardly be disposed to join in the cry which is so often raised against the " philosophes " that their " infidel and leveling " principles brought about the French Revolution. People, like the Marquis d'Argenson, with political eyes in their heads, saw that the revolution was inevitable before Rousseau wrote a line. In truth, the Bull " Unigenitus," the interested restiveness of the Parliaments, and the extravagancies and profligacy of the court had a great deal more influence in generating the catastrophe than all the " philosophes " that ever put pen to paper. But, un- doubtedly, Rousseau's extremely attractive and widely read writ- ings did a great deal to give a color of rationality to those princi- ples of '89 f which, even after the lapse of a century, are considered positive law, impatience of experience, and the preference of a priori to all other reason- ing " (pp. 89-92). I shall often have to quote " Ancient Law." The first edition of this admirable book was published in 1861, but now, after eighteen years of growing influence on thoughtful men, it seems to be forgotten, or willfully ignored, by the ruck of political speculators. It is enough to make one despair of the future that Demos and the Bourbons seem to be much alike in their want of capacity for either learning or forgetting. * Those who desire to do so with ease and pleasure should read M. Rocquain's " L'esprit r6volutionnaire en France avant la Revolution." It is really a luminous book, which ought to be translated for the benefit of our rising public men, who, having had the advantage of a public-school education, are so often unable to read French with comfort. For deeper students there is, of course, the great work of M. Taine, " Les origines de la France con- temporaine." f Sir H. Maine observes that the " strictly judicial axiom " of the lawyers of the Anto- nine era (" omnes homines natura aequales sunt " — all men are by nature equal), after pass- ing through the hands of Rousseau, and being adopted by the founders of the Constitution ON THE NATURAL INEQUALITY OF MEN. 763 by a good many people to be the Magna Charta of the human race. " Liberty, Equality, and Fraternity/' is still the war-cry of those, and they are many, who think, with Rousseau, that human sufferings must needs be the consequence of the artificial arrange- ments of society, and can all be alleviated or removed by political changes. The intellectual impulse which may thus be fairly enough con- nected with the name of the Genevese dreamer has by no means spent itself in the century and a half which has elapsed since it was given. On the contrary, after a period of comparative obscu- rity (at least outside France), Rousseauism has gradually come to the front again, and at present promises to exert once more a very grave influence on practical life. The two essays to which I have referred are, to all appearance, very little known to the present generation of those who have followed in Rousseau's track. None the less is it true that his teachings, filtered through innumerable channels and passing under other names, are still regarded as the foundations of political science by the existing representatives of the classes who were so much attracted by them when they were put forth. My friend Mr. John Morley, who probably knows more about Rousseau and his school than anybody else,* must have been entertained (so far as amusement is possible to the subject of the process of " heckling ") when Rousseau's plats, the indigestibility of which he exposed so many years ago, were set before him as a wholesome British dish ; the situation had a cer- tain piquancy, which no one would appreciate more keenly. I happened to be very much occupied upon subjects of a totally different character, and had no mind to leave them, when the nar- rative of this occurrence and some letters to which it gave rise, appeared in the " Times." But I have very long entertained the conviction that the revived Rousseauism of our day is working sad mischief, leading astray those who have not the time, even when they possess the ability, to go to the root of the superficially plausible doctrines which are disseminated among them. And I thought it was my duty to see whether some thirty years' training in the art of making difficult questions intelligible to audiences without much learning, but with that abundance of keen practical sense which characterizes English workmen of the better class, of the United States, returned to France endowed with vastly greater energy and dignity, and that "of all 'the principles of 1789' it is the one which has been least strenuously assailed, which has most thoroughly leavened modern opinion, and which promises to modify most deeply the constitution of societies, and the politics of states" ("Ancient Law," p. 96). * If I had not reason to think that Mr. Morley's " Rousseau," and Sir Henry Maine's " Ancient Law," especially the admirable Chapters III and IV, must be unknown to many political writers and speakers, and a fortiori to the general public, there would be no excuse for the present essay, which simply restates the case which they have so exhaust- ively treated. 764 THE POPULAR SCIENCE MONTHLY. would enable me to do something toward the counteraction of the fallacious guidance which is offered to them. Perhaps I may be permitted to add that the subject was by no means new to me. Very curious cases of communal organization and difficult ques- tions involving the whole subject of the rights of property come before those whose duty it is to acquaint themselves with the con- dition of either sea or fresh- water fisheries, or with the adminis- tration of fishery laws. For a number of years it was my fate to discharge such duties to the best of my ability ; and, in doing so, I was brought face to face with the problem of land-ownership and the difficulties which arise out of the conflicting claims of commoners and owners in severalty. And I had good reason to know that mistaken theories on these subjects are very liable to be translated into illegal actions. I can not say whether the letters which I wrote in any degree attained the object (of vastly greater importance, to my mind, than any personal question) which I had in view. But I was quite aware, whatever their other results, they would probably involve me in disagreeable consequences ; and, among the rest, in the necessity of proving a variety of state- ments, which I could only adumbrate within the compass of the space that the "Times" could afford me, liberal as the editor showed himself to be in that respect. What I purpose to do in the course of the present article, then, is to make good these short- comings ; to show what Rousseau's doctrines were, and to inquire into their scientific value — with, I hope, that impartiality which it beseems us to exhibit in inquiries into ancient history. Having done this, I propose to leave the application of the conclusions at which I arrive to the intelligence of my readers, as I shall thus escape collision with several of my respected contemporaries.* I have indicated two sources from which our knowledge of Rousseau's system may be derived, and it is not worth while to go any further. But it is needful to observe that the dicta of the author of the " Contrat Social," published in 1762, are not unfre- quently very hard — indeed, I might say impossible — to reconcile with those of the author of the " Discours," which appeared eight years earlier ; and that, if any one should maintain that the older * From Mr. Herbert Spencer's letter in the "Times" of November 27, 1889, I gather that he altogether repudiates the doctrines which I am about to criticise. I rejoice to hear it : in the first place, because they thus lose the shelter of his high authority ; secondly, because, after this repudiation, anything I may say in the course of the following pages against Rousseauism can not be disagreeable to him ; and, thirdly, because I desire to ex- press my great regret that, in however good company, I should have lacked the intelligence to perceive that Mr. Spencer had previously repudiated the views attributed to him by the land socialists. May I take this opportunity of informing the many correspondents who usually favor me with comments (mostly adverse, I am sorry to say) on what I venture to write, that I have no other answer to give them but Pilate's, " What I have written I have written " ? I have no energy to waste on replies to irresponsible criticism. ON THE NATURAL INEQUALITY OF MEN. 765 essay was not meant to be taken seriously, or that it has been, in some respects, more or less set aside by the later, he might find strong grounds for his opinion. It is enough for me that the same a priori method and the same fallacious assumptions per- vade both. The thesis of the earlier work is that man, in the " state of nature," was a very excellent creature indeed, strong, healthy, good, and contented ; and all the evils which have befallen him, such as feebleness, sickness, wickedness, and misery, result from his having forsaken the " state of nature " for the " state of civili- zation." And the first step in this downward progress was the setting up of rights of several property. It might seem to a plain man that the argument here turns on a matter of fact : if it is not historically true that men were once in this "state of nature" — what becomes of it all ? However, Rousseau tells us, in the pref- ace to the " Discours," not only that the " state of nature " is something which no longer exists, but that " perhaps it never ex- isted, and probably never will exist." Yet it is something " of which it is nevertheless necessary to have accurate notions in order to judge our present conditions rightly." After making this singular statement, Rousseau goes on to observe : " II faudrait meme plus de philosophie qu'on ne pense a celui qui entrepren- drait de determiner exactement les precautions a prendre pour faire sur ce sujet de solides observations." (More philosophy in- deed is needed than one thinks for him who undertakes to deter- mine exactly the precautions to be taken to make solid observa- tions on this subject.) And, certainly, the amount of philosophy required to base an argument on that which does not exist, has not existed, and perhaps never will exist, may well seem unattainable — at any rate, at first sight. Yet, apart from analogies which might be drawn from the mathematical sciences — where, for ex- ample, a straight line is a thing which has not existed, does not exist, and probably never will exist, and yet forms a good ground for reasoning ; and the value of which I need not stop to discuss — I take it that Rousseau has a very comprehensible idea at the bottom of this troublesome statement. "What I conceive him to mean is that it is possible to form an ideal conception of what ought to be the condition of mankind ; * and that, having done so, we are bound to judge the existing state of things by that * Compare " Ancient Law " : " The Law of Nature confused the Past and the Present. Logically, it implied a state of Nature which had once been regulated by Natural Law ; yet the jurisconsults do not speak clearly or confidently of the existence of such a state " (p. 73). " There are some writers on the subject who attempt to evade the fundamental difficulty by contending that the code of Nature exists in the future and is the goal to which all civil laws are moving " (p. 74). The jurisconsults conceived of Natural Law " as a system which ought gradually to absorb Civil Laws " (p. 76). " Its functions were, in short, remedial, not revolutionary or anarchical. And this unfortunately is the exact point 766 THE POPULAR SCIENCE MONTHLY. ideal. That assumption puts us on the "high priori road" at once. I do not suppose that any one is inclined to doubt the useful- ness of a political ideal as a goal toward which social conduct should strive, whether it can ever be completely realized or not ; any more than any one will doubt that it is useful to have a moral ideal toward which personal conduct should tend, even though one may never reach it. Certainly, I am the last person to ques- tion this, or to doubt that politics is as susceptible of treatment by scientific method as any other field of natural knowledge.* But it will be admitted that, great as are the advantages of hav- ing a political ideal, fashioned by an absolute rule of political conduct, it is perhaps better to do without one, rather than to adopt the first phantasm, bred of fallacious reasonings and born of the unscientific imagination, which presents itself. The be- nighted traveler, lost on a moor, who refuses to follow a man with a lantern, is surely not to be commended. But suppose his hesita- tion arises from a well-grounded doubt as to whether the seeming luminary is anything but a will o' the wisp ? And, unless I fail egregiously in attaining my purpose, those who read this paper to the end will, I think, have no doubt that the political lantern of Rousseauism is a mere corpse-candle and will plunge those who follow it in the deepest of anarchic bogs. There is another point which must be carefully borne in mind in any discussion of Rousseau's doctrines ; and that is the mean- ing which he attaches to the word " inequality." A hundred and fifty years ago, as now, political and biological philosophers found they were natural allies, f Rousseau is not intelligible without Buff on, with whose earlier works he was evidently ac- quainted, and whose influence in the following passage is obvious : It is easy to see that we must seek the primary cause of the differences hy which men are distinguished in these successive changes of the human constitu- tion ; since it is universally admitted that they are, naturally, as equal among at which the modern view of a Law of Nature has often ceased to resemble the an- cient " (p. 77). * In the course of the correspondence in the " Times " to which I have referred, I was earnestly exhorted to believe that the world of politics does not lie outside of the province of science. My impression is that I was trying to teach the public that great truth, which I had learned from Mill and Comte, thirty-five years ago ; when, if I mistake not, my well-meaning monitor was more occupied with peg-tops than with politics. See a lecture on the "Educational Value of the Natural History Sciences " delivered in 1854 (" Lay Sermons," p. 97). f The publication of Buffon's " Histoire Naturelle " began in 1749. Thus Rousseau was indebted to the naturalists ; on the other hand, in the case of the elder Darwin, who started what is now usually known as Lamarck's hypothesis, the naturalist was set spec- ulating by the ideas of the philosopher Hartley, transmitted through Priestley. See " Zoo- nomia," I, sect, xxxix, p. 483 (ed. 1796). I hope some day to deal at length with this curious fact in scientific history. ON THE NATURAL INEQUALITY OF MEN. 767 themselves as were the animals of each species before various physical causes had produced, in some of them, the varieties which we observe. In fact, it is not con- ceivable that these first changes, by whatever means they were brought about, altered, at once and in the same way, all the individuals of a species ; but some having become improved or deteriorated, and having acquired different qualities, good or bad, which were not inherent in their nature, the others remained longer in their original state ; and such was the first source of inequality among men, which is more easy to prove thus, in a general way, than to assign exactly to its true causes. (" Discours," preface.) In accordance with this conception of the origin of inequality among men, Rousseau distinguishes, at the outset of the "Dis- cours/' two kinds of inequality : the one which I term natural, or physical, because it is established by nature, and which consists in the differences of age, health, bodily strength, and intellectual or spiritual qualities; the other, which may be called moral, or political, because it depends on a sort of convention, and is established, or at least authorized, by the consent of mankind. This last inequality consists in the different privileges which some enjoy, to the prejudice of others, as being richer, more honored, more powerful than they, or by making themselves obeyed by others. Of course the question readily suggests itself : Before drawing this sharp line of demarkation between natural and political in- equality, might it not be as well to inquire whether they are not intimately connected, in such a manner that the latter is essen- tially a consequence of the former ? This question is indeed put by Rousseau himself. And, as the only answer he has to give is a piece of silly and insincere rhetoric about its being a question fit only for slaves to discuss in presence of their masters, we may fairly conclude that he knew well enough he dare not grapple with it. The only safe course for him was to go by on the other side and as far as the breadth of the road would permit ; and, in the rest of his writings, to play fast and loose with the two senses of inequality, as convenience might dictate. With these preliminary remarks kept well in view, we may proceed to the discussion of those fundamental theses of the " Dis- course " and of the " Social Contract " which Rousseau calls the " principes du droit politique." Rousseau defines his object thus: Je veux chercher si dans l'ordre civil il peut y avoir quelque regie d'administra- tion legitime et sure, en prenant les hommes tels qu'ils sont et les lois tels qu'elles peuvent etre. Je tacherai d'allier toujours dans cette recherche ce que le droit permet avec ce que l'interet present, afin que la justice et l'utilite ne se trouvent point divis6es.* (I seek to know if there may be in the civil order any legitimate and sure rule of civil administration, taking men as they are and laws as they might be. I shall try to combine in this research what the law permits with what interest prescribes, so that justice and utility shall not find themselves divided.) * " Contrat Social," livre 1". Compare Hobbes's dedication of " Human Nature " written in 1640: "They who have written of justice and policy in general do all invade each other 768 THE POPULAR SCIENCE MONTHLY. In other words, our philosopher propounds "sure," that is "absolute," principles which are, at once ethically and politically, sufficient rules of conduct, and that I understand to be the precise object of all who have followed in his track. It was said of the Genevese theorist, " Le genre humain avait perdu ses titres ; Jean- Jacques les a retrouve's " (the human race had lost its title-deeds ; Jean-Jacques found them again) ; just as his intellectual progeny declare that the nation ought to " resume " the landed property of which it has, unfortunately, lost the title-deeds. We are now in a position to consider what the chief of these principles of the gospel according to Jean-Jacques are : 1. All men are born free, politically equal, and good, and in the " state of nature " remain so ; consequently it is their natural right to be free, equal, and (presumably, their duty to be) good.* 2. All men being equal by natural right, none can have any right to encroach on another's equal right. Hence no man can appropriate any part of the common means of subsistence — that is to say, the land or anything which the land produces — without the unanimous consent of all other men. Under any other cir- cumstances, property is usurpation, or, in plain terms, robbery, f 3. Political rights, therefore, are based upon contract ; the so- called right of conquest is no right, and property which has been acquired by force may rightfully be taken away by force. J and themselves with contradictions. To reduce this doctrine to the rules and infallibility of reason there is no way, but, first, put such principles down for a foundation, as passion, not mistrusting, may not seek to displace ; and afterward to build thereon the truth of cases in the law of nature (which hitherto have been built in the air) by degrees, till the whole have been inexpugnable." However, it must be recollected that Hobbes does not start from a priori principles of ethics, but from the practical necessities of men in society. * " Contrat Social," v, pp. 98, 99.

Due allowance must be made for the pos- sible influence of such prejudice as may flow from this opinion upon my further conviction that, regarded from a purely theo- retical and scientific point of view, they are so plainly and demon- strably false that, except for the gravity of their practical conse- quences, they would be ridiculous. "What is the meaning of the famous phrase that " all men are born free and equal," * which gallicized Americans, who were as much " philosophes " as their inherited common sense and their practical acquaintance with men and with affairs would let them be, put forth as the foundation of the " Declaration of Independ- ence " ? I have seen a considerable number of new-born infants. Without wishing to speak of them with the least disrespect— a thing no man can do, without, as the proverb says, " fouling his own nest " — I fail to understand how they can be affirmed to have any political qualities at all. How can it be said that these poor little mortals who have not even the capacity to kick to any definite end, nor indeed to do anything but vaguely squirm and squall, are equal politically, except as all zeros may be said to be equal ? How can little creatures be said to be " free " of whom not one would live for four-and-twenty hours if it were not imprisoned by kindly hands and coerced into applying its foolish, wandering mouth to the breast it could never find for itself ? How is the being whose brain is still too pulpy to hold an idea of any de- scription to be a moral agent either good or bad ? Surely it must be a joke, and rather a cynical one too, to talk of the political status of a new-born child ! But we may carry our questions a step further. If it is mere abracadabra to speak of men being born in a state of political freedom and equality, thus fallaciously confusing positive equality — that is to say, the equality of powers — with the equality of impotences ; in what conceivable state of society is it possible that men should not merely be born, but pass through childhood and still remain free ? Has a child of fourteen been free to choose its language and all the connotations with which words became burdened in their use by generation after generation ? Has it been free to choose the habits enforced by precept and more surely driven home by example ? Has it been free to invent its own standard of right and wrong ? Or rather, henceforth, for the profit of a few ambitious persons, subjected the whole human race to labor, servitude, and misery.) — (" Discours," p. 278). Behold the quintessence of Rousseau- ism — method and results — with practical application, legible by the swiftest runner ! * ["All men are created equal" is the wording of the " Declaration."— Editor P. S. M.] VOL. XXXTI. 49 77o THE POPULAR SCIENCE MONTHLY. has it not been as much held in bondage by its surroundings and driven hither and thither by the scourge of opinion, as a veritable slave, although the fetters and the whip may be invisible and in- tangible ? Surely, Aristotle was much nearer the truth in this matter than Hobbes or Rousseau. And if the predicate "born slave" would more nearly agree with fact than " born free," what is to be said about " born equal " ? Rousseau, like the sentimental rhetorician that he was, and half, or more than half, sham, as all sentimental rhetoricians are, sagaciously fought shy, as we have seen, of the question of the influence of natural upon politi- cal equality. But those of us who do not care for sentiment and do care for truth may not evade the consideration of that which is really the key of the position. If Rousseau, instead of letting his children go to the infants trouves, had taken the trouble to discharge a father's duties toward them, he would hardly have talked so fast about men being born equal, even in a political sense. For, if that merely means that all new-born children are political zeros — it is, as we have seen, though true enough, nothing to the purpose ; while, if it means that, in their potentiality of be- coming factors in any social organization — citizens in Rousseau's sense — all men are born equal, it is probably the most astounding falsity that ever was put forth by a political speculator ; and that, as all students of political speculation will agree, is saying a good deal for it. In fact, nothing is more remarkable than the wide inequality which children, even of the same family, exhibit, as soon as the mental and moral qualities begin to manifest them- selves ; which is earlier than most people fancy. Every family spontaneously becomes a polity. Among the children, there are some who continue to be " more honored and more powerful than the rest, and to make themselves obeyed " (sometimes, indeed, by their elders) in virtue of nothing but their moral and mental qualities. Here " political inequality " visibly dogs the heels of " natural " inequality. The group of children becomes a political body, a civitas, with its rights of property, and its practical dis- tinctions of rank and power. And all this comes about neither by force nor by fraud, but as the necessary consequence of the innate inequalities of capability. Thus men are certainly not born free and equal in natural qualities ; when they are born, the predicates " free " and " equal " in the political sense are not applicable to them ; and as they de- velop, year by year, the differences in the political potentialities with which they really are born, become more and more obviously converted into actual differences — the inequality of political fac- ulty shows itself to be a necessary consequence of the inequality of natural faculty. It is probably true that the earliest men were ON THE NATURAL INEQUALITY OF MEN. 771 nomads. But among a body of naked, wandering savages, though, there may be no verbally recognized distinctions of rank or office, superior strength and cunning confer authority of a more valid kind than that secured by acts of Parliament ; there may be no property in things, but the witless man will be poverty-stricken in ideas, the clever man will be a capitalist in that same commod- ity, which in the long run buys all other commodities ; one will miss opportunities, the others will make them ; and, proclaim hu- man equality as loudly as you like, Witless will serve his brother. So long as men are men and society is society, human equality will be a dream ; and the assumption that it does exist is as un- true in fact as it sets the mark of impracticability on every theory of what ought to be, which starts from it. And that last remark suggests that there is another way of re- garding Rousseau's speculations. It may be pointed out that, after all, whatever estimate we may form of him, the author of works which have made such a noise in the world could not have been a mere fool ; and that if, in their plain and obvious sense, the doctrines which he advanced are so easily upset, it is probable that he had in his mind something which is different from that sense. I am a good deal disposed to think that this is the case. There is much to be said in favor of the view that Rousseau, having got hold of a plausible hypothesis, more or less unconsciously made up a clothing of imaginary facts to hide its real nakedness. He was not the first nor the last philosopher to perform this feat. As soon as men began to think about political problems, it must have struck them that, if the main object of society was the welfare of its members (and until this became clear, political ac- tion could not have risen above the level of instinct),* there were all sorts of distinctions among men, and burdens laid upon them, which nowise contributed to that end. Even before the great lev- eler, Rome, had actually thrown down innumerable social and national party-walls, had absorbed all other forms of citizenship into her own, and brought the inhabitants of what was then known as the world under one system of obligations — thoughtful * It is not to be forgotten that what we call rational grounds for our beliefs are often ex- tremely irrational attempts to justify our instincts. I can not doubt that human society existed before language or any ethical consciousness. Gregarious animals form polities in which they act according to rules conducive to the welfare of the whole society, although, of course, it would be absurd to say that they obey laws in the juridical sense. The polities of the masterless dogs in Eastern cities are well known. And, in any street of an English town, one may observe a small dog chased by a bigger, who turns round the moment he has entered his own territory and defies the other ; while, usually, after various manifestations of anger and contempt, the bigger withdraws. No doubt the small dog has had previous experience of the arrival of assistance under such circumstances, and the big one of the effects of sticks and stones and other odd missiles ; no doubt the associations thus ingrained are the prime source of the practical acknowledgment of ownership on both sides. I sus- pect it has been very much the same among men. 772 THE POPULAR SCIENCE MONTHLY. men were discovering that it was desirable, in the interest of soci- ety, that all men should be as free as possible, consistently with those interests ; and that they should all be equally bound by the ethical and legal obligations which are essential to social exist- ence. It will be observed that this conclusion is one which might be arrived at by observation and induction from the phenomena of past and present experience. My belief is that it is the conclu- sion which must be reached by those means, when they are rightly employed — and that, in point of fact, the doctrines of freedom and equality, so far as they were preached by the Stoics and others, would have not the least success, if they had not been so far ap- proved by experience and so far in harmony with human instincts that the Roman jurists found they could work them up with effect into practical legislation. For the a priori arguments of the phi- losophers in the last century of the republic, and the first of the empire, stand examination no better than those of the philoso- phers in the centuries before and after the French Revolution. As is the fashion of speculators, they scorned to remain on the safe if humble ground of experience, and preferred to prophesy from the sublime cloud-land of the a priori ; so that, busied with deduction from their ideal " ought to be," they overlooked the " what has been," the " what is," and the " what can be." It is to them that we owe the idea of living " according to na- ture " ; which begot the idea of the " state of nature " ; which be- got the notion that the " state of nature " was a reality, and that, once upon a time, " all men were free and equal " — which again begot the theory that society ought to be reformed in such a man- ner as to bring back these halcyon days of freedom and equality ; which begot laissez faire and universal suffrage ; which begot the theory so dear to young men of more ambition than industry, that while every other trade, business, or profession requires theoreti- cal training and practical skill, and would go to the dogs if those who carry them on were appointed by the majority of votes of people who know nothing about it and very little about them — the management of the affairs of society will be perfectly success- ful if only the people who may be trusted to know nothing will vote into office the people who may be trusted to do nothing. If this is the political ideal of the modern followers of Rous- seau, I, for my part, object to strive after it, or to do anything but oppose, to the best of my ability, those who would fain drive us that way. Freedom, used foolishly, and equality, asserted in words, but every moment denied by the facts of nature, are things of which, as it seems to me, we have rather too much already. If I mistake not, one thing we need to learn is the necessity of limit- ing individual freedom for the general good ; and another, that although decision by a majority of votes may be as good a rough- ON THE NATURAL INEQUALITY OF MEN 773 arid-ready way as can be devised to get political questions settled, yet that, theoretically, the despotism of a majority is as little jus- tifiable and as dangerous as that of one man ; and yet another, that voting power, as a means of giving effect to opinion, is more likely to prove a curse than a blessing to the voters, unless that opinion is the result of a sound judgment operating upon sound knowledge. Some experience of sea-life leads me to think that I should be very sorry to find myself on board a ship in which the voices of the cook and the loblolly boys counted for as much as those of the officers, upon a question of steering, or reefing top- sails ; or where the " great heart " of the crew was called upon to settle the ship's course. And there is no sea more dangerous than the ocean of practical politics — none in which there is more need of good pilotage and of a single, unfaltering purpose when the waves rise high. The conclusion of the whole matter, then, would seem to be that the doctrine that all men are, in any sense, or have been, at any time, free and equal, is an utterly baseless fiction. Nor does the proposition fare much better if we modify it, so as to say that all men ought to be free and equal, so long as the " ought " poses as a command of immutable morality. For, assuredly, it is not intuitively certain "that all men ought to be free and equal/' Therefore, if it is to be justified at all a priori, it must be dedu- cible from some proposition which is intuitively certain; and unfortunately none is forthcoming. For the proposition that men ought to be free to do what they please, so long as they do not infringe on the equal rights of other men, assumes that men have equal rights and can not be used to prove that assumption. And if, instead of appealing to philosophy, we turn to revealed religion, I am not aware that either Judaism or Christianity affirms the political freedom or the political equality of men in Rousseau's sense. They affirm the equality of men before God — but that is an equality either of insignificance or of imperfection. With the demonstration that men are not all equal under whatever aspect they are contemplated, and that the assumption that they ought to be considered equal has no sort of a priori foundation — however much it may, in reference to positive law, with due limitations, be justifiable by considerations of practical expediency — the bottom of Rousseau's argument, from a priori ethical assumptions to the denial of the right of an individual to hold private property, falls out. For Rousseau, with more logical consistency than some of those who have come after him, puts the land and its produce upon the same footing. " Vous 6tes per- dus si vous oubliez que les fruits sont a tous, et que la terre n'est a personne," says he. (You are lost if you forget that the fruits are for all and the land is not for any one.) 774 TEE POPULAR SCIENCE MONTHLY. From Rousseau's poiut of view, this is, in fact, the only ra- tional conclusion from the premises. The attempt to draw a dis- tinction between land, as a limited commodity, and other things as unlimited, is an obvious fallacy. For, according to him,* the total habitable surface of the earth is the property of the whole hu- man race in common. Undoubtedly, the habitable and cultivable land amounts to a definite number of square miles, which, by no effort of human ingenuity, at present known or suspected, can be sensibly increased beyond the area of that part of the globe which is not covered by water ; and therefore its quantity is limited. But if the land is limited, so is the quantity of the trees that will grow on it ; of the cattle that can be pastured on it ; of the crops that can be raised from it ; of the minerals that can be dug from it ; of the wind ; and of the water-power, afforded by the limited streams which flow from the limited heights. And, if the human race were to go on increasing in number at its present rate, a time would come when there would not be standing-ground for any more ; if it were not that, long before that time, they would have eaten up the limited quantity of food-stuffs and died like the locusts that have consumed everything eatable in an oasis of the desert. The attempt to draw a distinction between land as limited in quantity, in the sense, I suppose, that it is something that can not be imported — and other things as unlimited, because they can be imported — has arisen from the fact that Rousseau's modern fol- lowers entertain the delusion that, consistently with their princi- ples, it is possible to suppose that a nation has right of ownership in the land it occupies. If the island of Great Britain is the prop- erty of the British nation, then, of course, it is true that they can not have more than somewhere about ninety thousand square miles of land, while the quantity of other things they can import is (for the present, at any rate), practically, if not strictly, unlim- ited. But how is the assumption that the Britons own Britain, to be reconciled with the great dictum of Rousseau, that a man can not rightfully appropriate any part of this limited commodity, land, without the unanimous consent of all his fellow-men ? My strong impression is that if a party-colored 'plebiscite of Europeans, Chi- nese, Hindoos, negroes, red Indians, Maoris, and all the other inhabitants of the terrestrial globe were to decree us to be usurp- ers, not a soul would budge ; and that, if it came to fighting, Mr. Morley's late " hecklers " might be safely depended upon to hold their native soil against all intruders, and in the teeth of the most absolute of ethical politicians, even though he should prove from Rousseau — Exceedingly well That such conduct was quite atrocious. * As to Hobbes, but on different grounds. ON THE NATURAL INEQUALITY OF MEN. 77s Rousseau's first and second great doctrines having thus col- lapsed, what is to be said to the third ? Of course, if there are no rights of property but those based on contract, conquest, that is to say, taking possession by force, of itself can confer no right. But, as the doctrine that there are no rights of property but those based on the consent of the whole hu- man race — that is, that A. B. can not own anything unless the whole of mankind formally signify their assent to his ownership — turns out to be more than doubtful in theory and decidedly incon- venient in practice, we may inquire if there is any better reason for the assertion that force can confer no right of ownership. Suppose that, in the old seafaring days, a pirate attacked an East Indiaman — got soundly beaten and had to surrender. When the pirates had walked the plank or been hanged, had the captain and crew of the East Indiaman no right of property in the prize — I am not speaking of mere legal right, but ethically ? But if they had, what is the difference when nations attack one another ; when there is no way out of their quarrel but the appeal to force, and the one that gets the better seizes more or less of the other's territory and demands it as the price of peace ? In the latter case, in fact, we have a contract, a price paid for an article — to wit, peace — delivered, and certain lands taken in exchange ; and there can be no question that the buyer's title is based on con- tract. Even in the former alternative, I see little difference. When they declared war, the parties knew very well that they referred their case to the arbitrament of force ; and if contracts are eternally valid, they are fully bound to abide by the decision of the arbitrator whom they have elected to obey. Therefore, even on Hobbes's or Rousseau's principles, it is not by any means clear to my mind that force, or rather the state of express or tacit contract which follows upon force successfully applied, may not be plausibly considered to confer ownership. But if the question is argued, as I think it ought to be, on em- pirical grounds — if the real question is not one of imagined a priori principle, but of practical expediency — of the conduct which conduces most to human welfare — then it appears to me that there is much to be said for the opinion that force effectually and thoroughly used, so as to render further opposition hopeless, establishes an ownership * which should be recognized as soon as possible. I am greatly disposed to think, that when ownership established by force has endured for many generations, and all sorts of contracts have been entered into on the faith of such ownership, the attempt to disturb it is very much to be deprecated on all grounds. For the welfare of society, as for that of individual * Submission to the Revolution of 1688 by Jacobites could be advocated ethically on no other ground, though all sorts of pretexts were invented to disguise the fact. 776 THE POPULAR SCIENCE MONTHLY. men, it is surely essential that there should he a statute of limita- tions in respect of the consequences of wrong-doing. As there is nothing more fatal to nobility of personal character than the nurs- ing of the feeling of revenge — nothing that more clearly indicates a barbarous state of society than the carrying on of a vendetta, generation after generation — so I take it to be a plain maxim of that political ethic which does not profess to have any greater authority than agreeableness to good feeling and good sense can confer, that the evil deeds of former generations — especially if they were in accordance with the practices of a less advanced civilization, and had the sanction of a less refined morality — should, as speedily as possible, be forgotten and buried under better things. "Musst immer thun wie neu geboren" (must ever do as if new-born) is the best of all maxims for the guidance of the life of states, no less than of individuals. However, I express what I personally think, in all humility, in the face of the too patent fact that there are persons of light and leading — with a political au- thority to which I can make not the remotest pretension, and with a weight of political responsibility which I rejoice to think can never rest on my shoulders — who by no means share my opin- ion, but who, on the contrary, deem it right to fan the sparks of revenge which linger among the embers of ancient discords ; and to stand between the dead past and the living present, not with the healing purpose of the Jewish leader, but rather to intensify the plague of political strife, and hold aloft the brazen image of the father's wrongs, lest the children might perchance forget and forgive. However, the question whether the fact that property in land was originally acquired by force invalidates all subsequent deal- ings in that property so completely, that no lapse of time, no for- mal legalization, no passing from hand to hand by free contract through an endless series of owners, can extinguish the right of the nation to take it away by force from the latest proprietor, has rather an academic than a practical interest, so long as the evi- dence that landed ownership did so arise is wanting. Potent an organon as the a priori method may be, its employment in the region of history has rarely been found to yield satisfactory re- sults ; and, in this particular case, the confident assertions that land was originally held in common by the whole nation, and that it has been converted into severalty by force, as the outcome of the military spirit rather than by the consent, or contract, charac- teristic of industrialism, are singularly ill-founded. Let us see what genuine history has to say to these assertions. Perhaps it might have been pardonable in Rousseau to propound ON THE NATURAL INEQUALITY OF MEN 777 such, a statement as that the primitive land-owner was. either a robber or a cheat ; but, in the course of the century and a half which has elapsed since he wrote, and especially in that of the last fifty years, an immense amount of information on the subject of ancient land-tenure has come to light ; so that it is no longer par- donable, in any one, to content himself with Rousseau's ignorance. Even a superficial glance over the results of modern investiga- tions into anthropology, archaeology, ancient law, and ancient re- ligion, suffices to show that there is not a particle of evidence that men ever existed in Rousseau's state of nature, and that there are very strong reasons for thinking that they never could have done so, and never will do so. It is, at the least, highly probable that the nomadic preceded any other social state ; and, as the needs of a wandering hunter's or pastor's life are far more simple than any other, it follows that the inequalities of condition must be less obvious among nomads than among settled people. Men who have no costume at all, for example, can not be said to be unequally clothed ; they are, doubt- less, more equal than men some of whom are well clothed and others in rags, though the equality is of the negative sort. But it is a profound mistake to imagine that, in the nomadic condition, any more than in any other which has yet been observed, men are either " free " or " equal " in Rousseau's sense. I can call to mind no nomadic nation in which women are on an equality with men ; nor any in which young men are on the same footing as old men ; nor any in which family groups, bound together by blood ties, by their mutual responsibility for bloodshed and by common worship, do not constitute corporate political units, in the sense of the city * of the Greeks and Romans. A " state of nature " in which noble and peaceful, but nude and propertyless, savages sit in solitary meditation under trees, unless they are dining or amus- ing themselves in other ways, without cares or responsibilities of any sort, is simply another figment of the unscientific imagination. The only uncivilized men of whom anything is really known are hampered by superstitions and enslaved by conventions, as strange as those of the most artificial societies, to an almost incredible de- gree. Furthermore, I think, it may be said with much confidence that the primitive "land-grabber" did not either force or cheat his co-proprietors into letting him fence in a bit of the land which hitherto was the property of all. The truth is, we do not know, and probably never shall know completely, the nature of all the various processes by which the ownership of land was originally brought about. But there is * I may remind the reader that, in their original senses, ir6\is and civitas mean, not an aggregation of houses, but a corporation. In this sense, the City of London is formed by the freemen of the city, with their common councilors, aldermen, and lord mayor. 778 THE POPULAR SCIENCE MONTHLY. excellent ground for sundry probable conclusions* in the fact that almost all parts of the world, and almost all nations, have yielded evidence that, in the earliest settled condition we can get at, land was held as private or several property, and not as the property of the public, or general body of the nation. Now pri- vate or several property may be held in one of two ways. The ownership may be vested in a single individual person, in the ordinary sense of that word ; or it may be vested in two or more individuals forming a corporation or legal person ; that is to say, an entity which has all the duties and responsibilities of an indi- vidual person, but is composed of two or more individuals. It is obvious that all the arguments which Rousseau uses against indi- vidual land-ownership apply to corporate land-ownership. If the rights of A, B, and C are individually nil, you can not make any more of your 0 by multiplying it by 3. (A, B, C) — the corpora- tion— must be a usurper if A, B, and C, taken each by himself, is so. Moreover, I think I may take it for granted that those who desire to make the state universal land-owner would eject a cor- poration from its estates with even less hesitation than they would expel an individual. The particular method of early land-holding of which we have the most wide-spread traces is that in which each of a great num- ber of moderate-sized portions of the whole territory occupied by a nation is held in complete and inalienable ownership f by the males of a family, or of a small number of actual or supposed kindred families, mutually responsible in blood feuds, and wor- shiping the same God or Gods. No female had any share in the ownership of the land. If she married outside the community, she might take a share of the movables ; and, as a rule, she went to her husband's community. If, however, the community was short of hands, the husband might be taken into it, and then he acquired all the rights and responsibilities of the other members. Children born in the community became full members of it by domicile, so to speak, not by heredity from their parents. This primitive " city " was lodged in one or more dwellings, each usu- ally standing in a patch of inclosed ground ; of arable land in the immediate neighborhood of the dwellings ; while pasture and un- cleared forest land lay outside all. Each commune was as jealous of its rights of ownership as the touchiest of squires ; but, so long as the population was as scanty in proportion to the occupied ter- ritory as was usually the case in ancient times, the communities got along pretty peaceably with one another. Any notion that all * For the difficulties which attach to the establishment of such probable conclusions, see the remarkable work of M. Fustel de Coulanges, " Recherches sur quelques problemes d'Histoire : Les Germains." f Inalienable, that is, without the consent of the whole owning community. ON TEE NATURAL INEQUALITY OF MEN. 779 the communities which made up the nation had a sort of corpo- rate overlordship over any one, still more that all the rest of the world had any right to complain of their " appropriation of the means of subsistence," most assuredly never entered the heads of our forefathers. But, alongside this corporate several ownership, there is strong ground for the belief that individual ownership was recognized, to a certain extent, even in these early times. The inclosure around each dwelling was understood to belong to the family inhabiting the dwelling ; and, for all practical pur- poses, must have been as much owned by the head of it as a modern entailed estate is owned by the possessor for the time being. Moreover, if any member of the community chose to go outside and clear and cultivate some of the waste, the reclaimed land was thenceforth recognized as his — that is to say, the right of ownership, in virtue of labor spent, was admitted.* Thus it is obvious that, though the early land-holders were, to a great extent, collective owners, the imaginary rights of mankind to universal land-ownership, or even of that of the nation at large to the whole territory occupied, were utterly ignored ; that, so far from several ownership being the result of force or fraud, it was the system established with universal assent ; and that, from the first, in all probability, individual rights of property, under cer- tain conditions, were fully recognized and respected. Rousseau was, therefore, correct in suspecting that his "state of nature" had never existed — it never did, nor anything like it. But it may be said, supposing that all this is true, and supposing that the doctrine that Englishmen have no right to their appropriation of English soil is nonsense ; it must, nevertheless, be admitted that, at one time, the great body of the nation, consisting of these numerous land-owning corporations, composed of comparatively poor men, did own the land. And it must also be admitted that now they do not ; but that the land is in the hands of a relatively small number of actually or comparatively rich proprietors, who constitute perhaps not one per cent of the population. What is this but the result of robbery and cheating ? The descendants of the robbers and cut-throat soldiers who came over with William of Normandy have been true to their military instincts, and have " conveyed " the property of the primitive corporations into their own possession. No doubt, that is history made easy ; but here, once more, fact and a priori speculations can not be made to fit. Let us look at the case dispassionately, and by the light of real history. No doubt, the early system of land-tenure by collective several ownership was excellently adapted to the circumstances in which mankind found themselves. If it had not been so, it would * Rousseau himself not only admits but insists on the validity of this claim in the " Contrat Social," liv. i, chap. ix. 78o THE POPULAR SCIENCE MONTHLY. not have endured so long, nor would it have been adopted by all sorts of different races — from the ancient Irish to the Hindoos, and from the Russians to the Caffres and Japanese. These circum- stances were in the main as follows : that there was plenty of land unoccupied ; that population was very scanty and increased slowly ; that wants were simple ; that people were content to go on living in the same way, generation after generation ; that there was no commerce worth speaking of ; that manufactures were really that which they are etymologically — things made by the hands ; and that there was no need of capital in the shape of money. Moreover, with such methods of warfare as then existed, the system was good for defense, and not bad for offense. Yet, even if left to itself, to develop undisturbedly, without the intrusion of force, fraud, or militarism in any shape, the com- munal system, like the individual - owner system or the state- owner system, or any other system that the wit of man has yet devised, would sooner or later have had to face the everlasting agrarian difficulty. And the more the communities enjoyed gen- eral health, peace, and plenty, the sooner would the pressure of population upon the means of support make itself felt. The diffi- culty paraded by the opponents of individual ownership, that, by the extension of the private appropriation of the means of sub- sistence, the time would arrive when men would come into the world for whom there was no place, must needs make its appear- ance under any system, unless mankind are prevented from mul- tiplying indefinitely. For, even if the habitable land is the prop- erty of the whole human race, the multiplication of that race must, as we have seen, sooner or later, bring its numbers up tp the maximum which the produce can support ; and then the in- teresting problem in casuistry, which even absolute political eth- ics may find puzzling, will arise : Are we, who can just exist, bound to admit the new-comers who will simply starve them- selves and us ? If the rule that any one may exercise his freedom only so far as he does not interfere with the freedom of others is all-sufficient, it is clear that the new-comers will have no rights to exist at all, inasmuch as they will interfere most seriously with the freedom of their predecessors. The population question is the real riddle of the sphinx, to which no political CEdipus has as yet found the answer. In view of the ravages of the terrible monster over-multiplication, all other riddles sink into insignifi- cance. But to return to the question of the manner in which indi- vidual several ownership has, in our own and some other coun- tries, superseded communal several ownership. There is an exceedingly instructive chapter in M. de Laveleye's well-known work on " Primitive Property," entitled " The Origin of Inequality ON THE NATURAL INEQUALITY OF MEN. 781 in Landed Property." And I select M. de Laveleye as a witness the more willingly, because lie draws very different conclusions from the facts he so carefully adduces to those which they appear to me to support. After enumerating various countries in which, as M. de Lave- leye thinks, inequality and an aristocracy were the result of con- quest, he asks very pertinently : But how were they developed in such countries as Germany, which know nothing of conquerors coming to create a privileged caste above a vanquished and enslaved population ? Originally we see in Germany associations of free and independent peasants like the inhabitants of Uri, Schwyz, and Unterwalden at the present day. At the close of the middle ages we find, in the same country, a feudal aristocracy resting more heavily on the soil, and a rustic population more completely enslaved than in England, Italy, or France (p. 222). The author proceeds to answer the question which he pro- pounds by showing, in the first place, that the admission of the right of individuals and their heirs to the land they had re- claimed, which was so general, if not universal, created heredi- tary individual property alongside the communal property, so that private estates arose in the waste between the sparse com- munal estates. Now, it was not every family or member of a community that was enterprising enough to go out and clear waste lands, or that had the courage to defend its possessions when once obtained. The originally small size of the domains thus acquired, and the strong stimulus of personal interest, led to the introduction of better methods of cultivation than those tra- ditional in the communes. And, finally, as the private owner got little or no benefit from the community, he was exempted from the charges and corvees laid upon its members. The result, as may be imagined, was that the private proprietors, aided by serf- labor, prospered more than the communities cultivated by their free members, seriously hampered them by occupying fresh waste lands, yielded more produce, and furnished wealth, which, with the help of the majorat system, remained concentrated in the hands of owners who, in virtue of their possessions, could main- tain retainers ; while, freed from the need to labor, they could occupy themselves with war and the chase, and, as nobles, attend the sovereign. On the other hand, their brethren, left behind in the communes, had little chance of growing individually rich or powerful, and had to give themselves up to agricultural toil. The Bishop of Oxford, in his well-known " Constitutional History of England " (vol. i, p. 51), puts the case, as his wont is, concisely and precisely : " As the population increased, and agriculture itself improved, the mark system must have been superseded everywhere." No doubt, when the nobles had once established themselves, they often added force and fraud to their other means 782 THE POPULAR SCIENCE MONTHLY. of enlarging their borders. But, to begin with, the inequality was the result, not of militarism, but of industrialism. Clearing a piece of land for the purpose of cultivating it and reaping the crops for one's own advantage is surely an industrial operation, if ever there was one. Secondly, M. de Laveleye points out that the Church was a great devourer of commune lands : " We know that a member of the commune could only dispose of his share with the consent of his associates, who had a right of resumption; but this right could not be exercised against the Church. Accordingly, in these days of religious fervor, the faith- ful frequently left to the Church all that they possessed, not only their house and its inclosure, but the undivided share in the mark attached to it " (p. 225). Thus an abbot, or a bishop, became co- proprietor with the peasants of a commune; and, with such a cuckoo in the nest, one can conceive that the hedge-sparrows might have a bad time. " Already by the end of the ninth cent- ury one third of the whole soil of Gaul belonged to the clergy " (p. 225). But, if the men who left their property to the Church believed that they got their quid pro quo in the shape of masses for their souls, as they certainly did ; and if the churchmen be- lieved as sincerely (and they certainly did) that they gave valua- ble consideration for the property left them, where does fraud come in ? Is it not again a truly industrial operation ? Indeed, a keen-witted and eminent Scotch judge once called a huge be- quest to a church " fire insurance," so emphatically commercial did the transaction appear to him. Thirdly, personal several property was carved out of the cor- porate communal property in another fashion, to which no objec- tion can be taken by industrialism. Plots of arable land were granted to members of the commune who were skilled artificers, as a salary for their services. The craft transmitting itself from father to son, the land went with it and grew into an hereditary benefice. Fourthly, Sir Henry Maine * has proved in a very striking manner, from the collection of the Brehon laws of ancient Ire- land, how the original communal land-ownership of the sept, with the allotment of an extra allowance of pasture to the chief, as the honorarium for his services of all kinds, became modified, in con- sequence of the power of keeping more cattle than the rest of the sept, thus conferred on the chief. He became a lender of cattle at a high rate of interest to his more needy sept fellows, who when they borrowed became bound to do him service in other ways and lost status by falling into the position of his debtors. Hence the chief gradually acquired the characteristics of what naturalists * Sec " Early History of Institutions," epecially Lecture vi. ON THE NATURAL INEQUALITY OF MEN. 783 have called " synthetic " and " prophetic " types, combining the features of the modern gombeen-man with those of the modern rack-renting landlord, who is commonly supposed to be a purely imported Norman or Saxon product, saturated with the very spirit of industrialism — namely, the determination to get the highest price for an article which is to be had. As a fact, the condition of the native Irish, under their own chiefs, was as bad in Queen Elizabeth's time as it has ever been since. Again, the status of the original commoners of the sept was steadily altered for the worse by the privilege which the chief possessed, and of which he freely availed himself, of settling on the waste land of the commune such broken vagabonds of other tribes as sought his patronage and protection, and who became absolutely depend- ent upon him. Thus, without war and without any necessity for force or fraud (though doubtless there was an adventitious abun- dance of both), the communal system was bound to go to pieces, and to be replaced by individual ownership, in consequence of the operation of purely industrial causes. That is to say, in conse- quence of the many commercial advantages of individual owner- ship over communal ownership ; which became more and more marked exactly in proportion as territory became more fully occu- pied, security of possession increased, and the chances of the suc- cess of individual enterprise and skill as against routine, in an industrial occupation, became greater and greater. The notion that all individual ownership of land is the result of force and fraud appears to me to be on a level with the pecul- iarly short-sighted prejudice that all religions are the results of sacerdotal cunning and imposture. As religions are the inevita- ble products of the human mind, which generates the priest and the prophet as much as it generates the faithful ; so the inequality of individual ownership has grown out of the relative equality of communal ownership in virtue of those natural inequalities of men which, if unimpeded by circumstances, can not fail to give rise quietly and peaceably to corresponding political inequalities. The task I have set myself is completed, as far as it can be within reasonable limits. I trust that those who have taken the trouble to follow the argument will agree with me that the gos- pel of Jean-Jacques, in its relation to property, is a very sorry affair— that it is the product of an untrustworthy method, applied to assumptions which are devoid of foundation in fact ; and that nothing can be more profoundly true than the saying of the great and truly philosophical English jurist, whose recent death we all deplore, that speculations of this sort are rooted in " impatience of experience, and the preference of a priori to all other methods of reasoning." 784 THE POPULAR SCIENCE MONTHLY. Almost all the multitudinous causes which concurred in bring- ing about the French Revolution are happily absent in this coun- try ; and I have not the slightest fear that the preaching of any amount of political fallacy will involve us in evils of the magni- tude of those which accompanied that great drama. But, seeing how great and manifold are the inevitable sufferings of men ; how profoundly important it is that all should give their best will and devote their best intelligence to the alleviation of those sufferings which can be diminished, by seeking out, and, as far as lies within human power, removing their causes ; it is surely lamentable that they should be drawn away by speculative chimeras from the attempt to find that narrow path which for nations, as for indi- vidual men, is the sole road to permanent well-being.— Nineteenth Century. SLOYD : ITS AIM, METHOD, AND RESULTS. By FEIMANN B. AENGEIMSSON. SLOJD, anglicized into sloyd, is a Swedish word, meaning dex- terity or manual skill (compare old Norse slclegd, cunning, and English sly). Of late, however, the word has been restricted to denote a system of manual training. This system came originally from Finland, but was adopted some fifteen years ago in Sweden, and there perfected in its meth- ods. The Finnish teacher Zygnaus is its originator ; but to Messrs. A. Abrahamson and O. Salomon,* of Naas, Sweden, is due the honor of having adapted it to the use of schools and made it gen- erally known. For fifteen years their institute has been growing in importance, and in that time over one thousand teachers have been trained there and sent out to different parts of the world. Hence this method has often been called the Naas system of manual training. The aim of the system is not to teach the pupil a trade, but to educate him. Its primary object is to insure a healthy physical and mental development, while its secondary object is to secure general dexterity useful in every vocation. The method is based upon the principle that a harmonious mental development is best secured through a harmonious physi- cal development, promoted by exercise. It proceeds first to call the physical activities into play, and by stimulating, strength- ening, and training these, it seeks to awaken, develop, and culti- vate the powers of the mind. Taking advantage of the pupil's * For more detailed accounts of the Sloyd system, consult the writings of Dr. 0. Salo- mon, Miss C. Lord, Prof. W. T. Ilarris, P. M. Sluys, etc. SLOYD: ITS AIM, METHOD, AND RESULTS. 785 natural activity, it permits him to engage in work so arranged as to lead him to discover the principles to be taught, to apply his knowledge, and thus obtain a useful training. The instruction is on the inductive plan, mainly through prac- tical exercises, but in part oral. Class instruction is used only when general directions must be given, as when commencing a class, explaining the use of tools, position, etc. Otherwise, indi- vidual instruction is employed, it being found to yield the best results ; but, as the pupil advances, the teacher's aid becomes less necessary. The training consists mainly in performing certain exercises calculated to give general dexterity, promote health and strength, and at the same time develop the perceptive faculties, ingenuity of construction, concentrated attention, love of exactness, and ar- tistic taste. The exercises, though necessarily varying with the require- ments of different localities, must embody the leading principles of the system ; be conducive to health and development ; pleasing, so as to interest the pupil ; varied, so as to exercise the various faculties ; and graded, so that the pupil may, with the mere guid- ance of the teacher, pass from the first and simplest to the last and most difficult. Series of objects or models made of wood (Figs. 1 and 2) are used to illustrate the exercises. These models, though varying according to localities, must always represent useful articles ; be of pleasing forms, in which curved lines largely enter ; be varied, so as to demand variety of skill ; and be systematically arranged, so that each subsequent model requires an exact copy of the pre- ceding. All careless work must be excluded, as also polishing and painting, in order to secure the more thorough workmanship. The tools comprise all the essential ones used in carpentry — as the knife, the hammer, the center-bit, the try-square, compasses, saws, files, planes, etc. The work-room must be spacious, airy, and well lighted, and the work-benches should turn, so that when the pupil is at work the light shall fall on him chiefly from the left side. The teaching should not be intrusted to others than those who have natural qualifications for the work, have been in- structed in the science of education, and trained in the system of Sloyd. The courses of instruction must necessarily depend on circum- stances, but the instruction falls naturally into three stages, viz., an elementary, an intermediate, and an advanced course ; or, more simply, into an elementary course for children, and an advanced course for older pupils. In any case the period of instruction may be made to coincide with that of the common school. What relation Sloyd bears to other systems of manual training VOL. XXXVI. — 50 786 THE POPULAR SCIENCE MONTHLY. can here be merely indicated in a very general way. This system agrees with ether systems of manual training in making physical i 'rise the basis of its instruction and training, also in adopting the inductive method of teaching. But it differs from most of these in using wood as the only material for construction, and in the form of its models. From the various handicrafts in wood, as carpentry, wood-carving, wood-engraving, etc., it differs in not Fig. 1.— Models. being a trade ; and from other Sloyd systems, in avoiding their tendency of either aiming at a mere technical skill or a mere mental discipline. Thus, it differs from those adopted in France and Denmark in being less technical, from those in Germany in being less theoretical, and from the Russian system chiefly in lay- ing greater stress on the utility of the articles and introducing curved lines at an earlier stage. How far Sloyd may be adopted in the public schools has been extensively discussed in Europe. That it should be introduced into the public schools, either as a separate branch of study or incorporated with the ordinary branches as a continuation of the Kindergarten system, has been earnestly urged by some schools of pedagogy, and as strenuously opposed by others. It is not pos- sible to enter fully into the subject here ; but it may be noted that SLOYD : ITS AIM, METHOD, AND RESULTS. 787 the principal teacher of Sloyd, Director Salomon, unhesitatingly claims that its introduction into the public schools would be bene- ficial, directly promoting general health, and indirectly by facili- tating the acquisition of other studies. It has been claimed by many advocates of this system that it is better than most others, supplies a healthful training, without becoming on the one hand a mere trade, or on the other a mere theoretic study ; that while it trains in general dexterity and pro- motes physical development, it at the same time strengthens and disciplines the faculties of the mind ; cultivating the perceptives. Fig. 2. — Models. especially the senses of form and order ; training the power of comparison, constructiveness, and concentration of thought ; be- sides awakening a liking for manual labor, respect for manual workers, love for the true, and taste for the beautiful. Whatever may be said to the contrary, so much is certain that, if properly taught, Sloyd is a valuable means to education and an important complement to the ordinary branches of school studies. This is borne out by its phenomenal success in Sweden, its extensive adoption in countries where education is most advanced, as in Germany, France, and Great Britain, and by its growing popu- larity on this side of the Atlantic. THE POPULAR SCIENCE MONTHLY. Some idea of how Sloyd is succeeding on this continent may be gleaned from the following extract from the " Midsummer Report of the Sloyd School " at No. 10 Warrenton Street, Boston : " This school was started by Mrs. Quincy A. Shaw. It is super- intended by Mrs. F. S. Fiske. The Sloyd instruction is given by Mr. G. Larsson, formerly a teacher in the normal school at Naas, Sweden. " The school began in November, 1888, in the Warrenton Street Chapel, the intention being to show the principles of the Swedish method of manual training — modified, however, according to American requirements. The course from November 1, 1888, to July 1, 1889, has been carried on with continually growing inter- est on the part of the pupils. As the course has been free, with no obligatory attendance whatever, it is astonishing to see with what interest and attention it has been followed, not only hj the grown-up pupils, but especially by the younger ones. ' The number of pupils who have received instruction is above one hundred and forty ; of these, fifty-three were lady teachers, twenty working-girls, thirty-seven boys between the ages of ten and sixteen years, ten young men, and twenty from the Horace Mann School (deaf and dumb). " About fifty of the pupils have begun the normal course, but the time has been too short for any of these to finish the series. ' The pupils have to complete a copy of each model as exactly as possible before they begin the next number. " As soon as they have completed the series, they will have a few lessons in sharpening tools ; also get practice in teaching pupils ; and by short discussion obtain some knowledge of the different systems of manual training in wood, their advantages, disadvantages, etc." Since this report was written the school has steadily increased, so that now the pupils number over two hundred. Of these about eighty are boys, the rest being chiefly teachers from the city schools. There are two courses provided, and a third more ad- vanced course will be added if necessary. The time required for completing a course varies from one hundred and fifty to two li mid red hours, according to the pupil's ability. The pupils are divided into classes of twenty each, and these meet at stated times, generally twice a week, the lessons being usually of two hours' duration. Admission to the school is limited to teachers, boys l'i( >m the public schools, and deaf-mutes from the Horace Mann School. Tuition is free.

A Glimpse of the Sloyd School in Boston. — It is a rather remarkable building, that chapel at No. 10 Warrenton Street. The first floor is used for Kindergarten and evening school, the second for a church and lecture-room, while on the third floor is a Sloyd school. Here the visitor enters a large, well-lighted hall (Fig. 3), with two rows of benches along the sides, and at each bench is a student. It may be that a class of teachers is at work, teachers mature in years and experience, of delicate frames, care-worn countenances, watchful eyes, aquiline noses, now and then adorned with a pair of gold spectacles — gentlemen, men of polite address, ladies of queenly deportment — all at present whittling or hammering, saw- ing or planing, like genuine carpenters, exercising many a deli- cate muscle now perhaps for the first time in their lives, working with a will, even enthusiasm, which can not be explained on the supposition that they are trying to atone for the sins of their quondam educators. No, they are here to educate themselves, that they may the better educate those placed in their charge ; and it is this which makes their work sublime, even sacred. Or it may happen that a class of youths are at work — boys from the pub- lic schools or the machine-shops, factory-girls and servant-girls ; youths who feel the irksome and unhealthy influence of hard service, who are debarred by utter poverty, arrogant pride, or blind custom, from obtaining that education which their gentle, aspiring, and noble natures desire — debarred from the full develop- ment and the free exercise of their God-given faculties ; youths of untutored talents as well as those of well-instructed minds are here. And all engage in the work ; all take hold with a will, even with joy. For they feel the blood course more freely in their veins, hear the wind breathe sweeter music, and see the light 79° THE POPULAR SCIENCE MONTHLY. weave a more lovely world of colors. Their dormant energies are awakened, the heightened color on the cheek, the lustrous laughing eye, the merry mobile lip, the fair white hand, the whole person speaks in eloquent language the pleasure which springs from progress, or a work well done. Fig. 3.— Free Slotd School— Normal Class. But it may be that neither mature teachers nor tender youths are at their benches, but playful, frolicsome children flitting about their work like butterflies about a flower, and working with glee, learning almost unconsciously. Here is a batch of boys, there a group of girls, who at other times might be called a little unruly ; they are now all attention, their minds concentrated on the curious models before them ; and, while the exercise lasts, there is no indi- cation of unrestrained spirits. But perhaps the school presents none of these sights, but a very different one ; a sight half sad, yet not without a ray of gladness ; a picture not composed of trained teachers, or boisterous youths, or prattling children, eagerly listening, and as eagerly speaking, but of a group of deaf and dumb. And now, if ever, you may see what intense enthusiasm may be thrown into manual training. The poor unfortunates deprived of hearing and of speech find here a new field in which to exercise their minds and express their ideas. By their very disabilities they are enabled to concentrate THE MYSTERIOUS MUSIC OF PASCAGOULA. 791 their minds better than their more fortunate brethren, and even outstrip them in excellence of workmanship. Among the boys there is a deaf-mute some sixteen years of age who surpasses all others in the school, a result attained not by superior talent but by close application. Near him another boy of magnificent build and great ability dashes off his work — now planing, now carving, with a master hand. On the other side of the room, in the midst of that row of girls — neat, even pretty girls — there are two most noticeable ; one a brunette, whose quick, observant eye omits nothing while her snow-white hand deftly draws and carefully carves the model. Beside her stands a quiet blonde with blue, thoughtful eyes, carefully examining her model ; and then, as if suddenly discovering some new principle, makes a gesture of joy and resumes her work. At the close of the exercise she takes the finished model to her teacher, and, with a pleasant smile, joyful feelings struggling for expression in her soulful face, says, in the deaf-mute language, " I love this work." THE MYSTERIOUS MUSIC OF PASCAGOULA. By CHAKLES E. CHIDSEY. ANY one examining a map of the Mississippi coast will find indicated thereon, about one hundred miles east of New Orleans, the town of Scranton, or East Pascagoula, situated at the mouth of the Pascagoula River. The waters of this river have become famous in "song and story" for the strange sounds which they give forth as they slowly make their way to the Gulf. For forty years or more a great deal has been written in prose and verse about this mysterious music of Pascagoula, yet no one that I know of has ever attempted to give an accurate description or a plausible explanation of the phenomenon. In the following paper it is my purpose to describe the sounds as I have often heard them, and for an explanation of the mystery to give a theory, long since advanced by Darwin and Rev. Charles Kingsley, to explain the cause of similar music heard on the southern coast of France. It was late one evening in September, 1875, that I first heard the mysterious music of Pascagoula. An old fisherman called me from the house where I then was, to come down on the river- bank and "hear the spirits singing under the water." Full of eager curiosity, I readily obeyed the summons, and, if what I heard can not be properly called music, it was certainly mysterious. From out of the waters of the river, apparently some forty feet 792 THE POPULAR SCIENCE MONTHLY. from its shelving bank, rose a roaring, murmuring sound, which gradually increased in strength and volume, until it had reached its height, when it as slowly descended. It may be represented as follows : Diapason . ± Crescendo. Diminuendo. It never advanced or receded, but seemed always in the same spot ; and, though I remained there some time, it never ceased, but continued to rise and .fall in the manner that I have indicated above. The reader may obtain a better idea of the mu- sic if he will place his ear against a telegraph-pole, the timber of which, acting as a sounding-board for the wires that are played upon by the wind, gives forth a strange, tremulous sound, that is an exact counterpart of the " music of Pascagoula " — with this difference, however, that whereas the music of the wires is very wavering and tremulous, that of the water rises and falls with a steady swell. One evening in October, some years after the event above mentioned, while seated on an old wharf on the banks of the Pas- cagoula River, idly watching the ever varying and shifting hues of the setting sun, pointing with my finger across the wide extent of marsh that stretched before me to a squall that was raging in the Gulf, I remarked to my companion how distinctly we could hear the roar of the wind, though the storm was so far off. " That," she replied, " is not the storm that you hear, but the mysterious music." Approaching the edge of the wharf upon which we sat, and leaning over, I soon ascertained the truth of her words, for from out of the water came a roaring, rushing sound like that of a mighty wind, that may be represented thus : The sound, however, was not caused by the wind passing be- tween the wharf and the water, as there was very little breeze where we were, and, though I visited the spot some time after- ward, it abated but little. I have been frequently told by fisher- men that, when fishing at night on the waters of the Pascagoula, should they hear the mysterious music and make an unusual sound by splashing the water with an oar, or jumping overboard, THE MYSTERIOUS MUSIC OF PASCAGOULA. 793 the music will instantly cease, to begin again as soon as all is quiet. A few days ago I was told, by a lady residing here, that one night this summer, while rowing upon the river, she heard the music. " As we approached the sound/' she said, " it seemed to go away from us, but we continued to follow it even some dis- tance up the bayou on the other side of the river, when, for fear of losing ourselves in the intricate windings of the bayou, we left it." My friend, the late Rev. R. G. Hinsdale, of Biloxi, has told me that at that place there are three different kinds of this music heard, viz. : the first is like that I have described ; the second is a quick, sharp note sounded at different intervals, like this : the third is another note repeated twice, as follows ~o~ ^ h „ h r> „ h — ts N =F ~ ik %*- —d— y— J— -j ^— *— ~-d * * *— ^— As I have before hinted, I have no theory of my own to offer in explanation of the strange phenomenon known as the mys- terious music of Pascagoula, but shall merely give the theory that was advanced by Darwin years ago. In his " Descent of Man," page 347 (revised edition), Darwin says, " The last point which need be noticed is that fishes are known to make various noises, some of which are described as being musical. Dr. Du- fosse*, who has especially attended to this subject, says that the sounds are voluntarily produced in several ways by different fishes : by the friction of the pharyngeal bones ; by the vibration of certain muscles attached to the swim-bladder, which serves as a resounding-board ; and by the vibration of the intrinsic muscles of the swim-bladder. By this latter means the Trigla produces pure and long-drawn sounds which range over nearly an octave. But the most interesting case for us is that of two species of Ophidium, in which the males alone are provided with a sound- producing apparatus, consisting of small movable bones, with proper muscles, in connection with the swim-bladder. The drum- ming of the Umbrinas in the European seas is said to be audible from a depth of twenty fathoms, and the fishermen of Rochelle assert that ' the males alone make the noise during the spawning- time, and that it is possible, by imitating it, to take them without bait.'

Pascagoula, I am unable to say ; but if Darwin's views are correct, and I have no doubt that they are, then we have a very probable explanation of the mysterious music ; if not, then we are as much in the dark as ever.* -•-*+- THE INDWELLING SPIRITS OF MEN. By Hon. Major A. B. ELLIS. IN the spring of 1889 an officer of the United States Army, who was visiting Nassau, N. P., for the benefit of his health, lent me a pamphlet, a reprint of Dr. Washington Matthews's " The Prayer of a Navajo Shaman," which had originally been pub- lished in the " American Anthropologist " for April, 1888, and at page 19 of that pamphlet I read as follows : "The suppliant is supposed, through the" influence of witch- craft, exercised either in this world, or in the lower world when in spirit he was traveling there, to have lost his body, or parts thereof — not his visible body, nor yet his soul, his breath of life — for both of these he knows himself to be still in possession of, but a sort of spiritual body which he thinks constitutes a part of him — the astral body, perhaps, of our theosophic friends. This third element of man belongs not only to his living person, but to things which pertain to it, such as his ejected saliva, his fallen hair, the dust of his feet, etc." What struck me in this passage was the curious analogy be- tween the belief thus stated to be held by the Navajos and one which, in the course of my investigation of the religious systems of the negroes of West Africa, I had discovered to be held by the various tribes of the Gold and Slave Coasts ; and it is with the object of calling the attention of American anthropologists to this third element in man that I venture to put forward this paper. The Navajo believes that there are three entities in man: (1) The * [Prof G. Brown Goode, in his " American Fishes," mentions several species to which the name Drum has been given because of their ability to produce sounds. In his account of the Sea Drum he says : " Another historical incident is connected with Pogonias. The legend of Pascagoula and its mysterious music, deemed supernatural by the Indians, is still current. ' It may often be heard there on summer evenings,' says a recent writer. ' The listener being on the beach, or, yet more favorably, in a boat floating on the river, a low, plaintive sound is heard rising and falling like that of an ^Eolian harp, and seeming to issue from the water. The sounds, which are sweet and plaintive, but monotonous, cease as soon as there is any noise or disturbance of the water.' Bienville, the French explorer, heard the music of Pascagoula when he made his voyage in 1699 to the mouths of the Mississippi, and his experiences are recorded in his narrative." Speaking of the Lake Drum, Prof. Goode remarks : " These names, ' Croaker,' ' Drum,' ' Thunder-pumper,' etc., refer to the croaking or grunting noise made by this species in common with most Sciae- noids. This noise is thought to be made in the air-bladder by forcing the air from one compartment to another." — Editor.] THE INDWELLING SPIRITS OF MEN. 795 corporeal man ; (2) his soul, the vehicle of independent personal ex- istence, which, at the death of the body, survives and continues its career in the land of spirits ; (3) his spiritual body, which Dr. Mat- thews terms his " third element." The Tshi-speaking negroes of the Gold Coast — that is, the Ashantis, Fantis, Wassaws, Gamans, and several other tribes — believe similarly in three entities : (1) The corporeal man ; (2) his soul, or ghost ; (3) the indwelling spirit of the living man, which they term his kra. Now, though the kra has frequently been confounded with the soul or ghost, it is essentially distinct. The soul or ghost only comes into being when the corporeal man ceases to exist, and so may be considered to be the latter deprived of his material body ; but the kra, the Tshi-speaking negro believes, existed independ- ently before the birth of the man, and after his death will con- tinue to exist equally independently of the soul or ghost. A kra may have, and almost always has, been a kra in the bodies of other men since deceased, and, at the death of the individual whose body he is now tenanting, will seek to enter the body of some new-born human being. Failing this, it enters the body of an animal, and, if unable to enter the body either of a human being or of an ani- mal, it becomes a sisa, a kra without a tenement, and wanders about the earth, causing sickness to mankind. The ghost or soul which, at the death of the corporeal man, proceeds to Dead-land, and there continues the former vocations of the man, and for whose service in Dead-land slaves and wives are sacrificed, and arms, implements, and clothing buried with the corpse, is the vehicle of individual personal existence, the true soul; and the kra, whose connection with the man commences with the birth and terminates at his death, is something quite different. The difference between the kra and the soul is also well shown by the different results which ensue when they quit the body. The kra can and does quit the body at will. Usually it does so only during the sleep of the man, who is unconscious of its de- parture, and its adventures are the occurrences of which the man dreams. If it should leave while the man is awake, the latter is only made conscious of it, if at all, by a yawn, a sneeze, a shudder, or some such slight convulsion, which indicates to him that his kra is going out. In any case, whether sleeping or waking, he suffers no pain, feels no inconvenience, and is subject to no appar- ent change consequent on the departure of his kra. The absence of the kra is, however, dangerous, as it affords an opportunity for a sisa, or kra without a tenement, to enter the vacant body, for which the insisa are believed to be always on the lookout. The man is not conscious of the entry of the sisa, and nothing hap- pens until the kra returns and attempts to eject the intruder, when the effect of the internal struggle is to throw the man into 796 THE POPULAR SCIENCE MONTHLY. convulsions. In this manner the West African negroes seek to account for epileptic and similar seizures ; they are what used to be termed cases of " possession," but they are not directly attrib- utable to the departure of the kra, per se. When, however, the soul quits the body, the latter falls at once into a motionless and lifeless condition. Sometimes, though but rarely, the soul returns, and then the man has been in a swoon or trance ; more frequently it does not return, and then the man is dead. It is in the hope that the soul may return that appeals to the dead to come back are always made, and that the corpse is kept until the signs of corruption show that the soul has gone for- ever. The difference, then, between the results of departure is clear. When the kra departs, there is no direct and immediate result, though the departure may lead to " possession " ; but when the soul departs, the direct and immediate result is suspended ani- mation or death. The Ewi-speaking peoples of the Slave Coast — the Awunas, Krepis, Dahomis, Mahis, etc. — hold exactly similar views ; the third element, or indwelling spirit of man, being by them termed a luivo. The Ga-speaking peoples of the eastern districts of the Gold Coast have modified the more original conception, and be- lieve that each individual has two kla (the Ga-term for kra), a male and a female, the former being of a bad disposition and the latter of a good. By all the tribes of these three lingual groups the indwelling spirit is believed to afford some protection to man. It receives oc- casional thank-offerings, and the anniversary of each individual's day of birth is held as a day sacred to the spiritual tenant. On this account the hra may be regarded in some respects as a guardian spirit, dwelling in the body of the man ; but it is more than that. Its close connection with the man himself is indicated by the fact of its nocturnal adventures during its absence from the body being remembered by the man when he awakes. The latter even feels physically the effects of his kra's actions ; and when the ne- gro awakes from sleep feeling stiff and unref reshed, or with limbs aching from muscular rheumatism, he invariably attributes these symptoms to the fact of his Icra having been engaged in some struggle or some severe toil. If, moreover, a man dreams of other men, he believes that his kra has met theirs ; consequently, the kra is held to have the outward appearance of the man whose body he tenants. Hence the kra is more than a mere tenanting or guardian spirit. He has, though doubtless only in a shadowy form, the very shape and appearance of the man ; and both the mind and body of the latter are affected by and register the results of the kra's actions. How the notion of such an existence came into being it is beyond the province of this paper to inquire. It is THE INDWELLING SPIRITS OF MEN. 797 sufficient that it does exist, and that the Jcra is believed to be essen- tially distinct from the soul or ghost, which, at the death of the body, proceeds to Dead-land, and there continues the life that the man led in the world. I am unaware if American anthropologists have considered this third element of man, and its bearing upon the theory of animism, or even if instances of the belief being held, other than that mentioned by Dr. Washington Matthews, have been recorded ; but in Europe it seems quite to have escaped notice, and the belief is not referred to in any one of the text-books of anthropology that I have examined. This is doubtless in consequence of the German missionaries in "West Africa having translated the words hra, Ma, and luivo as "soul/' a term which is not at all applicable, and which has led to the third element being confused with the soul proper. It is in its bearing upon that branch of animism which is termed Nature-worship that this third element seems most im- portant. The negroes of the Gold and Slave Coasts, like every other people low in the stage of civilization, believe that inani- mate as well as animate objects have souls or ghosts — a belief which is proved by the practice of burying arms, implements, utensils, etc., for the use of the dead in Dead-land. The soul or ghost of the dead hunter goes to Dead-land, and there continues the former pursuit of the man, using the souls or ghosts of the weapons buried with him ; but the negroes have gone beyond this, and, just as they believe man to possess a third element or indwell- ing spirit, so do they believe that every natural object, everything not made by human hands, has, in addition to its soul or ghost, a third element or spiritual individuality. They hold that just as, when the man dies, the hra of the man enters a new-born child, and the soul or ghost-man goes to Dead-land ; so, when the tree dies, the hra, so to speak, of the tree enters a seedling, and the ghost-tree goes to join the ranks of the shadowy forest in Dead- land. And it is these animating or spiritual tenants of natural objects and natural features that the negro fears, and consequently worships. The process is something like this : Some day a man falls into a river and is drowned. The body is recovered by the man's com- rades, and is found to present no sign of external injury which, in their experience, would account for death. Being necessarily ignorant of the processes by which life is maintained, and seeking for a cause to which to attribute the disaster, they conceive the spiritual tenant or spiritual individuality of the river to have killed their comrade. And to this day, when a negro is drowned, his friends say, " So-and-so " (the spirit or god of the river) " has taken him down." Whether it was with the design of accounting 798 THE POPULAR SCIENCE MONTHLY. satisfactorily for such accidents — for to man in a low state of cult- ure nothing happens by chance — that the negro extended to natural objects and features the theory of a third element which he had hitherto restricted to himself ; or whether he had already formed the belief that such objects and features possessed spiritual indi- vidualities, and such accidents only proved to him the malignity and power for evil of those beings, the result would be the same. In either case he would seek to propitiate these powerful beings, and that class of worship which we term Nature-worship would originate. The theory of animism is divided into two parts, namely : that which treats of the souls or ghosts of individual creatures or ob- jects, capable of continued existence after the death or destruction of the material part ; and that which treats of spiritual beings, or gods, who are held to affect and control man's life and the events of the material world. In explanation of the first belief we have the well-known theory advanced by Mr. Herbert Spencer, Dr. Ty- lor, and others, and which is now very generally accepted ; but for the origin of the second belief we have no such satisfactory ex- planation, and have to fall back upon the theory that the dei loci — the gods of mountains, rivers, lakes, rocks, and trees — are deified dead men, an explanation that will only apply in a few isolated cases. Here, however, on the Gold and Slave Coasts of "West Africa, we find ready to hand a belief which explains the origin of such beings. If a tree should fall in the forest and crush a man, those who witness the accident, or find the body crushed under the fallen tree, have no hesitation in immediately attributing the disaster to the indwelling spirit, or third element, of the tree. This is the belief held, and the explanation invariably given. Naturally, those indwelling spirits which time and experience show to be harmless, are not much regarded ; the indwelling spirits of stones, bushes, etc., are considered of but little importance, and, though the belief in their existence remains, they are disregarded, and the worship and offerings are applied to propitiate those which are believed to possess both the power and the desire to injure. Hence we find, generally speaking, that the features worshiped are such as rivers, lakes, the sea, cliffs, mountains, etc. — that is, localities in which accidents are more liable to occur. The in- dwelling spirits or third elements of such features are not regard- ed as being inseparably bound up with them. Like the hra of the man, each ordinarily resides in its own feature or object, but can and does leave it temporarily. At a later stage, when priest- craft has intervened, the indwelling spirit is held to enter the image, made by the priests to represent it, while sacrifice is being offered, and also the priest himself, who then becomes inspired. It is clear, from their construction, that the Tshi, Ga, and Ewi THE INDWELLING SPIRITS OF MEN. 799 languages all belong to one family, and that the tribes now speak- ing them are descended from one common stock. The question then arises, Is this an isolated belief which will account for the origin of Nature-worship in certain districts of West Africa, and must be limited to them ; or is it a wide-spread belief which will account for the origin of that form of worship generally ? Fur- ther researches can alone determine this satisfactorily, but there are certain indications which tend to show that the belief is wide- spread. It must be remembered that it is unusual for students of anthropology to come into direct contact with people in that con- dition which we term savagery, and ordinary travelers possessing, like all Europeans, the belief in one soul only, and perhaps never having conceived the possibility of a man supposing himself to possess a third element, would be very unlikely to make any in- quiries in this direction. Even if a communicative native stated to him his theory of an indwelling spirit, or third element, the traveler would perhaps doubt if he really understood him ; but people low in the stage of civilization are not communicative on such points. Consequently, we can not expect to find many indi- cations, but there are some. Cross tells us * that the Karens, who inhabit parts of Burmah, Tenasserim, and Siam, believe in two elements in addition to the corporeal man, viz., the thah, which seems to answer to the soul, and the la or kelah, which is described as a " life-phantom " ; and Williams,f that the Fijians say that a man's " shadow " or " dark- spirit" goes to Dead-land, and that his "light- spirit" stays near where he dies. These appear to be beliefs somewhat analogous to that in the Tcra, but these different elements have not yet been defined. The genius natalis of the Romans, too, presents many points of resemblance to the kra. Like it, it entered the man at birth, and attended him till death. It was regarded as a second spiritual self, and the anniversary of the birthday of the man was held as a day sacred to it, libations being offered to the image by which it was represented among the household gods. At a later period of the Roman dominion this belief was modified, and, as among the Ga-speaking peoples of the Gold Coast, a belief in two indwelling spirits, one good and one bad, was formed. It was the latter which appeared to Brutus in the camp at Sardis. " What art thou ? " said Brutus ; " art thou god or man ? " The apparition answered : " I am thy evil genius, Brutus. Thou wilt see me at Philippi." \ It is, however, in America that we find the greater number of indications. Foremost stands Dr. Washington Matthews's above- mentioned account, in which the belief of the Navajo in the third * "Journal of the American Oriental Society," vol. iv, p. 310. f "Fiji," vol. i, p. 241. % " Plutarch's Lives" (Marcus Brutus), p. 684. 800 THE POPULAR SCIENCE MONTHLY. element of man is directly stated ; and in connection with this there is the following passage from the " Ethnography and Phi- lology of the Hidatsa Indians/' * by the same learned author : " They " (the Hidatsa Indians) " worship everything in nature. Not man alone, but the sun, the moon, the stars, all the lower ani- mals, all trees and plants, rivers and lakes, many bowlders and other separated rocks, even some small hills and buttes which stand alone — in short, everything not made by human hands, which has an independent being, or can be individualized, pos- sesses a spirit, or, more properly, a shade. " To these shades some respect or consideration is due, but not equally to all. For instance, the shade of the cottonwood, the greatest tree of the upper Missouri Valley, is supposed to possess an intelligence which may, if properly approached, assist them in certain undertakings ; but the shades of shrubs and grasses are of little importance. . . . Formerly it was considered wrong to cut down one of these great trees, and, when large logs were needed, only such as were found fallen were used ; and to-day some of the more credulous old men declare that many of the misfortunes of the people are the result of their modern disregard for the rights of the living cottonwood." These views are exactly similar to those held by the negroes of the Gold and Slave Coasts. With them, as with the Hidatsa In- dians, the shades, or third elements, of shrubs and grasses, which experience has proved to be innocuous, are of little importance ; while, like the cottonwood, the Bombax, the giant of the West Afri- can forest, whose gray trunk frequently rises to a height of ninety feet before a single branch is thrown out, is reverenced. The Tshi-speaking peoples have indeed classed the indwelling spirits, or third elements, of these trees into a species called Srahmantin — monstrous beings, gray in color and with long hair, who hurl down the decayed trees upon passers-by. How did the Hidatsa Indians form the belief that "everything not made by human hands, which has an independent being, or can be individualized, possesses a spirit, or, more properly, a shade " ? Do they, like the Navajos, believe that they possess a third element ; and have they, like the negroes of the Gold and Slave Coasts, extended the belief to all nature, or has with them Nature-worship originated in some other way ? Among other instances reported from North America the fol- lowing may be mentioned : The Algonquins are said to believe in two " souls," one of which goes out during sleep, and whose adventures during its absence are the occurrences dreamed of, while the other stays with the body. The same people are also said to believe that sickness is caused by the man's " shadow " * Washington, Government Printing-Office, 18V7, p. 48. NORTHERN LIGHTS. 801 being detached from the body.* The Salish Indians of Oregon regard the spirit as distinct from the vital principle, and capable of quitting the body for a short time without the patient being conscious of its absence f ; while the Dakotas are said to believe in four " souls." The first belief seems to resemble the kra theory ; but here, as in most other cases, the use of the word " soul " tends to confuse the subject. When attention is called to the subject, many more instances will no doubt be forthcoming ; but here, at all events, is something to work upon : and, having regard to the great strides which the science of anthropology is making in the United States, it will not be difficult for American anthropologists to determine whether a belief in the possession of a third element by man is common to many tribes of the northern continent, and, if so, whether the origin of Nature-worship among such tribes may be attributed to an extension of this belief to natural objects and features. -♦♦♦- NORTHERN LIGHTS. Br welhelm stosz. THE inhabitants of northern Europe, who passed their days in the midst of vast forests, and whose fancy fashioned the forms of heroes and of gods from the mists that hung over their vales, naturally associated with the gods they worshiped the phenom- ena of northern lights, which to them were revealed in all their splendor. Thus, the Edda gives descriptions of naming steeds speeding to Walhalla, and of valkyries dashing on through seeth- ing flames. Nations that as yet rest close to Nature's breast do not seek explanations of such phenomena ; while those that have risen to a higher plane of culture are in possession of simple de- scriptions of these occurrences, and also of crude attempts at investigating Nature's wonders. Thus, in the old writings of the Chinese, whose realm was a flourishing one two thousand years before our time, there may be found many accounts of the occur- rence of northern lights. They observed red vapors arise in the northern heavens, which spread evenly to both sides ; sometimes the fiery sheen was encircled by a large white bow, and flaming rays pierced the vapors. Such descriptions can only refer to northern lights. In the Greek and Latin classics we find more detailed descrip- tions of similar phenomena. Aristotle, Cicero, Seneca, Pliny, Lucan, Plutarch, Tacitus, and others describe the appearance of * Tanner's "Narrative," p. 291. f "Primitive Culture," vol. i, p. 437. 8oz THE POPULAR SCIENCE MONTHLY. auroras more or less completely. Some authors, instead of giving a simple narration of events, seek for an explanation of what they observed. Of course, these attempts in the main are very naive and without any scientific value. Aristotle speaks of red beams in the heavens, of torches and of billows of fire. Seneca compares the phenomena to flashes of lightning, and writes about the blazing of the heavens. Accord- ing to him, " the gleaming flashes may be caused by violent winds, or by the heat of the upper regions of the air ; for, when the fiery phenomenon spreads far, it sometimes extends to the lower region, if it be inflammable." Pliny writes : " Fiery beams occur likewise ; such a one was seen when the Lacedaemonians, vanquished at sea, lost their sway over Greece. Sometimes the heavens cleave ; this is spoken of as a ' chasma.' But naught is more terrible for mortals than when a blood-red conflagration starts in the heavens, and from there falls to the earth. This happened in the third year of the one hundred and seventh Olympiad, when King Philip warred in Greece. I, however, believe that these phenomena, as all others, occur at times regulated by Nature, and are not, as most people suppose, to be ascribed to a variety of causes which their fancies invent. They have, however, been premonitors of great misfor- tune. As they occur so very rarely, the law which they obey re- mains hidden, and may not be traced/' Furthermore, " During the reign of the consuls Caius Csecilius and Cneius Papirius, and also at other times, light was seen in the heavens, so that night became as day." The words of Lucan, " Fire storming from the north," remind us of the sagas of northern tribes. The middle ages could not readily free themselves from the in- fluence of the mysterious. Wondrous phenomena, the true nature of which was not grasped and understood, were veiled in mys- tery, and ascribed to the workings of demons. This is proved by many records and traditions. Does not Shakespeare possibly refer to northern lights in " King Henry VI," Part III, act ii, scene 1 ? — Rich. See, how the morning opes her golden gates, And takes her farewell of the glorious sun ! How well resembles it the prime of youth, Trimm'd like a yonnker, prancing to his love! Edw. Dazzle mine eyes, or do I see three suns? Rich. Three glorious suns, each one a perfect sun ; Not separated with the racking clouds, But sever'd in a pale clear-shining sky. See, see! they join, embrace, and seem to kiss, As if they vow'd some league inviolable: Now are they but one lamp, one light, one sun. In this the heaven figures some event. NORTHERN LIGHTS. 803 Many investigators consider the observations of Gassendi, which relate chiefly to the phenomena of 1621, as the starting- point toward a more correct conception of the nature of northern lights. The first move toward a truly scientific investigation into the matter was made by Halley, who in 1716 suggested that auroras were a magnetic exudation from the northern pole of the globe. His contemporaries did not share Halley's opinion. Wolf, in Halle, maintained that the lights consisted of inflammable sul- phurous fumes. Descartes and Triewald saw in them only a re- flection of the snow and ice at the north pole. Mairan (1733) considered them formed by a blending of zodiacal light with the earth's atmosphere. The famous mathematician Euler adhered to a sort of nebular hypothesis and declared the aurora to be a phenomenon similar to that presented by the tails of comets. Halley had arrived at his view through the observation that the center line of the light-arc deviated to the west of the meridian to about the same extent as the north pole of a magnetic needle. This important discovery was followed by one made by Mairan, that the crown of the northern lights lies in the (prolonged) direc- tion of the dipping-needle ; and soon after this Hjoter, in Upsala, demonstrated the influence of the aurora on a magnetic needle placed horizontally (1741). It was by these discoveries that the relation between northern lights and magnetism was established. Winkler (1746) and Van Marum (1777) compared the former to the electric glow which can be produced in rarefied air. The veil of the mystery had been raised, but only to disclose a new query, for the demonstration of the cause of these relations was a problem the solution of which was reserved for modern science. How far the efforts in this direction have been crowned by success we are now to consider. Auroras are most frequently seen in the cold and in the north- ern temperate zone, rarely in the southern temperate zone, and hardly ever in the tropics. The places where they most frequently appear lie between the sixtieth and seventieth degrees of north latitude. In the form of an oval, they include the geographical as well as the magnetic north pole, which is to be found on the peninsula Boothia Felix, Iceland, the Kara Sea, northern Siberia, Bering Strait, Hudson Bay, Labrador, and Greenland. Northern lights have been seen as far down as the twenty-fifth degree of north latitude. In full splendor, however, they may be seen only in the northern polar regions to the seventy-fifth degree of lati- tude. Here Nature is displayed in all her grandeur. When the sun has set, and the gray veil of twilight is cast over the earth, the northern horizon grows darker and darker. Soon there may be distinguished a segment of the sky more somber than its back- ground ; this is hemmed in by white concentric arcs of light. 8 o4 THE POPULAR SCIENCE MONTHLY. Colored rays shoot forth therefrom in all directions. They inter- lace and intertwine until they seem to be •woven into one flut- tering band of color. And anon it changes to a sea of fire ! The rays leap upward far above the zenith, form there a flaming crown, and then sink back, to begin anew the wondrous play. The most beautiful descriptions and trustworthy observations we owe to Nordenskjold and Ekama. All explanations which have been attempted as to the origin and the cause of northern lights are based on analysis by the spectroscope, on the determination of the elevation, and on observations of the peculiar behavior of the magnetic needle. If northern lights are observed through a spectroscope, a char- acteristic yellowish-green line will always be seen, no matter how faint the light may be. If the phenomena are well pronounced, several red lines appear in the spectrum. What inferences may be drawn from these observations ? If a very powerful electric current is sent through what is called a Geissler tube filled with dried and rarefied air, sparks will flash from one platinum wire to the other, and if these are exam- ined by the spectroscope they show the characteristic yellowish- green line. In a tube filled with nitrogen these lines are especially well pronounced. As nitrogen is the predominant constituent of the air, we infer the northern lights to be a phenomenon similar to the glowing of the electric spark in dry and rarefied air, in which oxygen and nitrogen are the sole conductors of electricity. If white sunlight is caused to shine on a solution of chlorophyl (the green coloring matter of leaves), it shows a blood-red color. This phenomenon, when the reflected light appears of a different color from that which is transmitted, is termed fluorescence. Electric light possesses to a marked degree the property of calling forth fluorescence, as can easily be demonstrated by various experi- ments. It may hence be assumed that the red lines in the spec- trum of northern lights are due to the fluorescence of oxygen in the upper layers of air, caused by powerful electric discharges. The determination of the elevation of northern lights serves to confirm the foregoing conclusions, for it is a well-known fact that in the higher regions of the atmosphere the air is dry and rarefied. The height of the auroral crown has been found to be five hundred kilometres, the lower boundary being about seventy kilometres. Of greater importance for ascertaining the true nature of north- ern lights has been the demonstration of the relation these phe- nomena hold to terrestrial magnetism, a mysterious power of which our globe is the conductor. Powerful magnetic currents appear suddenly and disappear as quickly, and we are not able to name the cause of their existence. Like a vast ocean the magnetic force is constantly surging NORTHERN LIGHTS. 805 through our globe, here appearing, there receding, but forever seeking to attain its equilibrium. The instrument by which these occurrences are observed is the most simple conceivable — the magnetic needle. It is known that the direction and the inclina- tion of the needle point out the magnetic location of a place. From its movement the degree of magnetic attraction of any point may be accurately determined. If sudden deviations and fluctuations of the needle occur, this evidently is an indication that the magnetic condition of the earth has been disturbed. If such variations always occur simultaneously with the appearance of northern lights, this is to be regarded as proof that an inti- mate relation exists between these phenomena and terrestrial magnetism. Strong northern lights, in fact, exert so great an influence on the magnetic condition of the earth, that the appear- ance of the phenomenon in some northern latitude may be in- ferred from the sudden oscillations of the needle in places where the lights are not visible. But the most striking connection be- tween terrestrial magnetism and northern lights is shown by the position of the light-crown in the heavens. The center of this is always to be found at that point where the dipping-needle, if pro- longed, would meet the aurora. The rays emanating from the arc have the direction of the earth's magnetic power ; they are there- fore parallel, and only apparently converge to a point. The crown of light has in truth no fixed place in the heavens, but like the rainbow its position depends on the point from which it is ob- served, and thus moves with the observer. But the dipping-needle in every place points to the center of the crown. It may hence be asserted that the northern lights hold an inti- mate relation to the changes of terrestrial magnetism as indi- cated by the oscillation of the needle, and that both phenomena must have one and the same cause. The explanation of this cause has been sought in various ways, but an interpretation which would be universally accepted has thus far not been ad- vanced. One of the first attempts to solve the problem was made by the physicist De la Rive, of Geneva, in 1862. It was based on an experiment devised by him, in which he attempted an imita- tion of these phenomena on a small scale. He held that vapors charged with positive electricity rise into the higher regions of the atmosphere, while the earth remains charged with the nega- tive fluid. When the vapors are driven by the trade-winds to the poles, as soon as the tension is sufficient to overcome the non-con- ducting property of the air, which like an insulator lies between the earth and these vapors, the positive and the negative electricity come together. This process is accompanied by the appearance of light. The earth and the upper layer of the atmosphere must hence be regarded as an electrical condenser, with the lower layers 8o6 THE POPULAR SCIENCE MONTHLY. of air as the separating medium. An actual proof that the north- ern lights are caused by electric currents in the atmosphere was attempted by Lemstrom in 1883. He covered the plateaus of two mountains in northern Finland with a network of copper wires raised several metres above the ground and provided it with hun- dreds of metal points. The whole was insulated and connected with a zinc plate buried in damp ground in the plain below. A continuous electric current from the air to the ground was notice- able, and a light which appeared hovering over the metal points showed, when examined by the spectroscope, the characteristic line of the auroral spectrum. The theories, however, according to which the northern lights are a flowing together of terrestrial and atmospheric electricity of opposite kinds, leave unanswered the question as to the origin of these electric fluids. As no adequate cause could be found on the globe for such a tremendous evolution of electricity, attention was directed to the sun as the source of it all. Why should not Helios, the giver of all light and life of our world, be as well the creator of that inexhaustible force of nature that is revealed in the splendors of the northern lights ? As the endless supply of light and heat which is radiated into space by the sun, is accounted for by the contraction of that body, this may also be assigned as the cause of the stupendous genera- tion of electricity. According to the theory of Kant and Laplace, the sun and other heavenly bodies are assumed to have been formed by the condensation of vapors which originally filled all space. This condensation is still going on in the sun in conse- quence of the enormous radiation of heat into space, and with it the consequent contraction. Possibly also there might be suggested as a cause the cooling process which the sun is undergoing. It may be assumed, too, that vast amounts of electricity are hurled into space with the ignited masses of gas, whose eruption from the sun may be con- stantly observed. But it is more probable that the sun acts upon the earth by induction. Try the following experiment : Two insu- lated spheres are placed near one another, but without being in contact. On one of these spheres a bar of metal is placed, to which there is fastened a screen made of some good conducting material. If one of the spheres is charged with a certain kind of electricity, say, for instance, negative electricity, the opposite kind — in this case positive electricity — will, by induction, be generated on the other sphere. A corresponding amount of negative electricity will in the mean time be discharged on to the screen. An action similar to this may be assumed to be going on between the sun and the earth. The sun's electricity, which may be assumed to be negative on NORTHERN LIGHTS. 807 account of the preponderance of metal in the composition of that body, generates positive electricity on the earth by induction, while the negative electricity passes over into the atmosphere sur- rounding the earth. The constitution of the air at different times and at different places favors this process more or less. The con- ducting metallic rod of our electrical experiments may be consid- ered here as being replaced by mountain-peaks projecting high into the air. If the equatorial currents, already mentioned by De la Rive, are borne in mind, it is evident that the air at the poles must be highly electrified, and that an exchange must then and there take place between the negative electricity and the positive (induced) electricity. This exchange gives rise to phenomena of light iden- tical with those observed as northern lights at the north pole and as southern lights at the south pole. This theory is strengthened by the observation that northern lights are closely connected with the appearance of sun-spots and protuberances on the sun. Already in former times a certain periodicity of northern lights was noticed. Besides the annual period in which they appear most frequently at the times of the equinox, and least frequently at the times of the solstices, a period of eleven years has been observed, corresponding closely to that of the sun-spots, the maximum of which coincides with the maxi- mum of northern lights. The appearance of sun-spots and protuberances, the connection between which was pointed out by Tacchini in 1885, may be re- garded as signs of changes occurring on the sun, probably involv- ing increased combustion. This increased activity must influence the induced terrestrial electricity, and in consequence also the phenomena of northern lights. The variations and declinations of the magnetic needle, moreover, give indubitable proof of the connection between the periods of sun-spots and the electrical condition of the earth. It should not seem strange that the terms electric and mag- netic condition have been here used as synonymous. Since Oer- sted's discovery of the influence of the electric current on the mag- netic needle, and Ampere's theory of magnetism, electricity and magnetism are regarded as merely two different forms of one and the same force of nature. — Translated for the Popular Science Monthly from Ueber Land und Meet. Prof. Flower expressed the opinion, in his presidential address before the British Association, that an impartial survey of the recent progress of paleonto- logical discovery must lead to the conclusion that the evidence in favor of the doctrine of a gradual transformation of living forms is steadily increasing. 8o8 THE POPULAR SCIENCE MONTHLY. DRAGONS, FABLED AND REAL. By M. MAUEICE MAINDEON. THE geological age of reptiles was marked by various curious, seemingly only partly perfected forms, which appear to have passed away without leaving any permanent descent. To it be- long the relics of those flying reptiles, the Rhamphorhynchus and the Pterodactyls. The type of the pterodactylean wing was not at all like that of the wings of birds, which were yet to come, and were beginning to appear when the reptilian era approached its close. The apparatus for flying was not formed by any essential modification of the limbs, but rather, like that of the bats, was constituted by a broad fold of the skin, attached to and sustained by the digits of the fore-limb. The last or outer digit, greatly elongated, formed a rigid side bordering and sustaining the para- chute, which was further attached along the full length of the arm, and in the Rhampliorhynchus was continued to the tail. These animals also had a long tail ending in a membrane, sus- tained by rigid ribs, that served as a kind of rudder. There were giants and dwarfs among the pterosaurians. Of the former were the Pteranodus, of the Kansas Cretaceous ; and of the latter, little Jurassic pterodactyls, which were not larger than a lark. The hieratic traditions of dragons appear at first sight to have been inspired* by the singular forms of these monsters; and it would be easy enough to suppose that the simple-minded figure- makers of the middle ages were acquainted with the pterosauri- ans, and patterned after them in sculpturing the dragons and griffins which they set up at church entrances. But they did not. Man's imagination is always capable of associating different forms into individuals, and even of inventing new forms. That the dragons of art were such inventions is proved by the awkward attachments which the artists affixed to their strange conceptions. Some of their creatures, if living, would have had a hard task to fly with the wings they gave them ; and others would have been greatly embarrassed to make use of all the appendages with which a hand more lavish than wise had endowed them. Movement by flying, the realization of which is still only a dream for man, has had a charm for the mystics of all ages. All religions concur in the common fancy of putting wings on the shoulders of their gods, genii, cherubim, angels, and seraphim. There were necessary for the transportation of such forms, for company and service, and to do battle for them, animals having forms likewise supernatural and agile ; whence hippogriffs, DRAGONS, FABLED AND REAL. 809 chimseras, and dragons. St. Michael the archangel, with the wings of a bird, lies low and slays the fallen angel Lucifer, having bats' wings. Dragons have also had their contests with saints. St. George defeated a monstrous dragon ; other holy per- sonages followed his example, and the times became very hard for gargoyles, tarasques, and guivres. Many of the dragons were Fig. 1.— Winged Dragons. (From a MS. of the Fourteenth Century. Book of the " Wonders of the World.") slain, and an old monkish chronicle tells how the skin of one of them was hung from an arch in a church. The historians and wise men of antiquity did not forget to describe these monsters. Pliny speaks of a precious stone, called dracontias, which could only be found in the head of a dragon. St. Augustine informs us that " the dragon often rests in his den ; but whenever he feels the moisture of the air he is able to rise on his wings and fly with great impetuosity." Other authors exhibit dragons ejecting fire and smoke from their burning throats, and enveloping in flames the audacious enemy who ventures to attack them. Such fables found credence as late as the sixteenth century. Even the grave Gessner believed in the existence of these creatures, and has said : " Numerous dragons are found in Ethiopia, a fact to be attributed to the heat that prevails in that country. They are also to be found in India and Libya, where they reach a length of fifteen feet, and the thickness of the trunk of a tree ; but they are generally larger in India than in any other country. Two kinds of dragons are known : those that live in the mountainous country are large, alert, and swift, and have a crest, while those that live in marshy regions are sluggish and idle. The former have wings, and the latter have not ; some have feet, and can get rapidly over the ground. Their vision is sharp, their hearing delicate. They rarely sleep, and for that reason the poets have made them guardians of treasures that man can not get. Near their abodes the air is noisome with their breath, and rings with their hissings." 51* 8io THE POPULAR SCIENCE MONTHLY. Fia. 2.— Flying Dragons op Malaysia, Draco volans and flmbriatm. (Prom specimens brought home by M. Maurice Maindrou.) These wonders, like other things of the kind, have had their day. The only dragons with which science now concerns itself are the little saurians, which are classed by some naturalists with DRAGONS, FABLED AND REAL. 811 the acrodont iguanans and by others with the agamians, and of some of which we give representations. There live in the forests of India, the Malay Archipelago, and the Philippine Islands, lizards, whose speckled dress and odd forms have long made them objects of interest to collectors. They live exclusively on insects, which they hunt with extreme agility of pursuit along the trunks and among the branches of trees. In whatever spot they may be hiding, their variegated liveries of gray and brown, speckled with black, yellow, or green, mask them effectively and cause them to pass unperceived in the cracks or among the inequalities of the bark. Squatting under this cover, they await the coming of some insect within reach of them ; or they may be seen running rapidly and suddenly covering consid- erable space, by a kind of flight, to place themselves upon another tree or fix themselves near a vine. Nature has been, in fact, pleased to facilitate the movements of these lively and graceful beings by an ingenious artifice. By the aid of their parachute, dragons can execute leaps in the air of considerable length, and pass from one tree to another as if by flying. But it must not be supposed that they can fly after the manner of birds. They can descend rapidly, describing a large parabola, sometimes almost a horizontal, but can not fly upward. I have frequently observed these pretty little saurians in Java. The first time I saw one I succeeded in shooting him with a small- bored gun loaded with fine shot. When I picked my victim up I was somewhat surprised to find that I had a dragon ; for its jerky and irregular flight along a large tree had caused me to suppose that it was some kind of a grasshopper or moth, which I could not get in any other way than by shooting. The dragons, as Cuvier says, fly by means of their ribs. Their first six pairs of false ribs, instead of being attached to the sternum, are drawn out and prolonged, so as to constitute the framework of a kind of umbrella, the covering of which is formed of a wide membrane making a fold in the skin of the flanks. This membrane is independent of the limbs. When at rest, it is folded up along each flank ; but it can be quickly un- folded and spread out in case of need. The name patagium has been given to it. The head and neck are ornamented with crests and dewlaps, often variegated with brilliantly defined colors ; and a long tail gives them a singular gait which is not without grace. The harmless little flying lizards inhabit forests and garden trees ; and nothing is more amusing than to watch their manoeu- vres, when, not aware that they are observed, they execute their gambols in the full flush of freedom. Running swiftly along the trees, stopping instantaneously, snapping up an insect or retiring 812 THE POPULAR SCIENCE MONTHLY. disappointed after they have missed it; pursuing one another; inflating their dewlaps and depressing their crests when enraged, they fly away spasmodically to drop a few yards farther along, down upon another tree, along which they continue their evo- lutions. In some dragons the tympanum is visible, in others it is hidden by a fold of the skin. A special genus (Dranuncidus) has been constituted for the latter, while the former compose the genus Draco. This genus is represented by six species, of which three inhabit the island of Java ; one, recognizable by its vertical nostrils, is peculiar to continental India ; the fifth is native to the island of Timor ; and the sixth is found at Pulu Penang. The Dranunculus inhabits Amboyna in the Moluccas, Celebes, and the Philippine Islands. The dragons are the only existing reptiles that possess organs of aerial locomotion. Other saurians have folds of skin along the flanks ; but in no other of them is this disposition so developed as in a curious geckotian, the Ptychozoon homacephalum of Java and other Sunda Islands. A broad membrane extending from the temples to the tail, where it is divided into slit lobes, is broad- ened along the flanks. Without reaching the dimensions of the patagium of the dragons, or possessing its rigid supports, it rep- resents a kind of parachute, the importance of which may have been augmented by long use ; or else we may regard these exten- sions of the skin as survivals of a provision which sedentary or profoundly changed habits have rendered useless. It may be added that the livery of the Ptychozoon is of such a nature as to assure it all the advantages of protective resemblance. The green color, yellowish on the upper side of the body, greenish along the flanks, varied with brown lines or transverse brown fasciae, constitutes a general tone which becomes, with wonderful ease, confounded with the bark and parasitic plants with which the trees are covered where they pass their lives. — Translated for the Popular Science Monthly from La Nature. [To this account of these interesting animals we add a por- trait of the frilled lizard (Chlamydosaurus Kingii), which pos- sesses an appendage of different structure from the wings of the dragons, but at the first view reminding one of them. The frill, which is its conspicuous ornament, is covered with scales and is toothed on the edge. It does not come of full size till the animal is grown, and increases — according to Wood — in regu- lar proportion to the age of the owner. In the young it does not even reach the base of the fore-limbs, while in the adult it extends well beyond them. M. F. Mocquard, who observed one of the animals during several weeks, is of the opinion that it serves the lizard as a kind of parachute, sustaining it during its DRAGONS, FABLED AND REAL. 8i3 Fig. 3.-The Chlamtdosaurus.

According to Captain Grey, who observed it in nature, " when not provoked or disturbed it moves quietly about, with its frill lying back in plaits upon the 8 14 THE POPULAR SCIENCE MONTHLY. body ; but it is very irascible, and directly it is frightened it ele- vates the frill or ruff and makes for a tree, where, if overtaken, it throws itself upon its stern, raising its head and chest as high as it can upon the fore-legs, then, doubling its tail underneath the body, and displaying a very formidable set of teeth from the con- cavity of its large frill, it boldly faces an opponent, biting furi- ously whatever is presented to it, and even venturing so far in its rage as to fairly make a charge at its enemy." M. Mocquard says it is quite inoffensive. It is nearly three feet in length, including its very long tail, is of a tawny color, with mottles on the back and blackish rings on the tail. The teeth on its fringe have white ends, and at a distance look like pearls. It belongs to the family of the agamians, and is represented only by a single species, 'in Australia. — Editor.] ALCHEMIST'S GOLD. By M. A. DE EOCHAS. 64 n^HE definite and unchangeable existence of sixty-six distinct -L elements, as we regard them now, would assuredly never have occurred to an ancient philosopher,, or rather would have been dismissed by him as ridiculous : it had to be imposed upon us by the incontestable force of the experimental method. Is this, then, the final -#imit of our conceptions and hopes? Not at all; for really this limit has never been accepted by chemists except as a present fact, which they have always hoped to pass by." This paragraph, quoted from Berthelot's " Origins of Chem- istry," explains why so many distinguished men have spent their days in seeking the transmutation of metals. Did they find it ? Excellent minds assure us that they did not, because, in spite of the infinitely more powerful forces we now have at our disposal, we have not been able to decompose any metal. Others maintain that the reasoning is not conclusive; for numerous industrial processes have been lost, and we knew how to convert alcohol into vinegar long before we could analyze either substance ; and there is one element — time — which the moderns, with their intensive life, can not use as their predecessors did. Where is the man now who' would bind himself down for years to make the projecting powder or the philosopher's stone — representing the hypothetical ferment of inorganic substances— or who could count enough upon the future to bequeath the continuation of his experiments to his heirs, as did the adepts of old ? There have been many alchemists who, notwithstanding the satirical definition of their art—" Ars sine arte ; cujus principium mentiri, medium laborare et finis mendicare " (" An art without ALCHEMIST'S GOLD. 815 art ; the beginning of which is to lie, the middle to work, and the end to beg ") — have acquired considerable wealth, the source of which it is hard to divine in any other way. M. Louis Figuier has collated the stories of the principal of them in his " History of Alchemy." I purpose in this article to describe some medals which were struck from gold which was said to have been com- pounded. I have seen one of the pieces, and tried to buy it for purposes of analysis, but the holder would not sell it. Probably an interesting collection might be made of such medals. In 1312 Raymond Lulle went to the British Islands in an effort to induce Kings Edward III and Robert Bruce to engage in a crusade, and promised to pay all the expenses of the expedition by means of his art. King Edward, more concerned about making gold than about going to the Holy Land, furnished the alchemist with a laboratory in the Tower of London ; and there Raymond, according to a declaration in his will, at a single opera- tion converted fifty pounds of mercury, lead, and tin into " gold." This " gold " was used in striking " rare nobles," some of which weighed as much as ten ducats, and must, therefore, have been as large as a French hundred-franc piece. Under the name of Ray- mond's nobles, they have been much sought for by English col- lectors. King Henry VI granted to several alchemists the right of making gold and silver out of the base metals. The products of their industry were probably used for coining the false money, the emission of which provoked prohibitory measures from the Scotch Parliament. Conrad Barchusen, a Dutch chemist of the beginning of the eighteenth century, assumed that the " gold " of Henry VI was obtained by putting mercury and sulphate of copper in an iron crucible with a little water. The copper, set free by the action of the iron, formed with the mercury an amal- gam which, washed and pressed to drive out the soluble sub- stances and the excess of mercury, gave on fusion a metal having the color of gold, but lighter, and readily taking the impress of the die. At about the same time, Bafbe de Cilley — wife of the Emperor Sigismund of Germany — pretended that she had found the phi- losopher's stone, in order to make her subjects accept an alloy of copper and arsenic for silver, and an alloy of gold, copper, and silver for gold. The alchemist Jean de Laaz solicited from her the privilege of being present at one of her transmutations. He detected the cheat, and was simple enough to reproach her Majesty for having bungled ; and for this he barely escaped going to prison. Jacques Cceur obtained from Charles VI of France, in consid- eration of his possession of the secret, power to coin money of 816 THE POPULAR SCIENCE MONTHLY. " silver," some of the pieces of which were described by De Planis Campy as still existing in 1633. They bore his name and the three hearts of his arms. Monconis * tells of a merchant of Lubeck who transformed lead into a hundred " gold " livres in the presence of Gustavus Adolphus, King of Sweden ; and who furnished the gold from which ducats were coined, bearing on one side the figure of the prince, and on the other side his arms, associated with alchemic symbols, in recollection of the origin of the metal. The merchant died some years afterward, leaving an enormous fortune, although his trade had been insignificant. Christian IV of Denmark, in 1646, appointed as " alchemist to the king " Gaspar Harbach, who made him some " gold," from which were coined medals bearing the inscription " Vide mira Do- mini (' Behold the wonders of the Lord'), 1647," beneath the sign O — O, designating mercury. An Austrian named Richtausen, in 1648, received as a bequest from one of his friends a casket containing precipitating powder ; with a grain of this powder, the Count de Riitz, director of the mines of the empire at Prague, in the presence of the Emperor Ferdinand III and the absence of Richtausen, transformed three livres or six marks of mercury into five marks of " gold." Rodolph had struck in this " gold " a medal which still existed in the Treas- ury at Vienna in 1797. It represents the god of the sun carrying the caduceus and having wings on his feet — all by way of reminder of the formation of "gold" by the aid of mercury, f In 1650 the emperor made a second precipitation at Prague, from lead ; and the medal struck on this occasion bore the inscription " Aurea progenies plumbo prognata parente " ( " Golden progeny of a lead parent "). This medal was still shown in the last century, in the collection of the Chateau d'Ambras (Tyrol). Richtausen received for his discovery the characteristic title of Baron of Chaos. General Paykhul, in 1706, made for King Charles XII of Swe- den, with lead and a few grains of his powder, under the sur- veillance of artillery-general Hamilton and the chemist Hieme, a mass of "gold" sufficient for the coinage of one hundred and forty-seven ducats ; a commemorative medal, struck on the occa- sion, from the same " gold," weighed two ducats and bore the in- scription "Hoc aurum arte cliimica conflavit Uolmice- 1706, O. A. V. Paikhull " (" This gold O. A. V. Paikhull produced by chemi- cal art at Holm in 1706 "). * " Voyage d'Allemagne." f Arsenic (to apcreviniv, the male) was one of the first substances tried for the purpose of transmutation. Its vapors whitened copper (which was considered a female element, was dedicated to Venus, and was represented by the sign s ), forming an arseniuret ; and this change was for a long time regarded as the beginning of transmutation. ALCHEMIST'S GOLD. 817 In 1704 a goldsmith of Lubeck, named Stolle, received a visit from a stranger, supposed to be the celebrated adept Lascaris, who, after a discussion respecting the transmutation of metals, left with him, as a proof of the possibility of the operation, an ingot weighing about a half-livre, which he said he had just made ; he asked Stolle to treat it with antimony to purify it, heat it, and cut it into seven pieces. He then left two of the pieces with the goldsmith as a souvenir, and added eight ducats. One of the pieces was given to King Augustus of Poland, and the other was deposited in the collection of medals at Lubeck. They bore the inscription " O tu . . . philosophorum " (" O thou ... of philosophers !"), which the adept had had engraved by the gold- smith. A Provencal locksmith, named Jean Troins, who called him- self the Sieur Delisle,* fabricated in the presence of M. de Saint- Maurice, president of the mint at Lyons, and at the Chateau Saint- Auban, two ingots of " gold," one from mercury and the other from lead. On trying to strike medals from this preparation at Lyons, the minter found it " so hard that it was not possible to work it." It was then sent to Paris, to the controller-general of finance, who had a number of medals struck from it bearing the inscription " Aurum ex arte factum " (" Gold made by art "). One of the medals was deposited in the Royal Cabinet, and, according to Langlet-Dufresnoy, its allotted square was still existing at the mint in 1762. I have handled and have an impression of a piece which, although the inscription is not identical with that described by Dufresnoy, was most probably made from Delisle's metal, f Its density is perceptibly different from that of gold, and that should give it a place in the class of tokens without value. Some spots of verdigris disappeared under the action of nitric acid, which did not attack the rest of the metal. Delisle likewise made, under similar circumstances, but with a different powder, an ingot of " silver," from which two crowns, two half-crowns, two quar- ters, and three ten-sous pieces were struck. In 1717 Landgrave Ernest Louis of Hesse-Darmstadt, who * Delisle is accused of having been the servant of Lascaris, and of having assassinated him in Savoy, in order to steal his powder. After this crime, in 1706, he established him- self at Sisteron, where he married and soon achieved a great local notoriety by changing nails, knives, shoe-buckles, rings, etc., of iron and steel into " gold " or " silver." Some of these transformed objects might, perhaps, still be found in the country if one should be at the pains of searching for them. Delisle resided in succession at Sisteron, the chateau of Palud Digne, where he is said to have enriched a merchant named Taxis ; at Castellane, and at Senez, where he performed several times before the bishop. f Possibly, however, this was a mock token, like those which were struck in England in 1815, when Napoleon was sent to St. Helena. That token was just like a twenty-franc piece, and bore the figure of the emperor on one side and a ship on the other, with the inscription " This is copper." vol. xxxvi. — 52 818 THE POPULAR SCIENCE MONTHLY. was an amateur alchemist, received by mail a little box containing two packages of powder, one red and the other white, with direc- tions for using them. He was thus able to enjoy the pleasure of himself changing lead into " gold " and " silver." From the " gold " he struck a few hundred ducats, bearing on one side his name and effigy, and on the other the lion of Hesse and his initials, E. L. From the " silver " he struck a hundred thalers bearing his name and likeness on one side, and on the other the inscription " Sic pla- cuit Deo in tribulationibus " (" Thus it has pleased God in tribula- tions "), 1717, with the lion of Hesse and his initials, surrounded by four crowns. These operations made so much stir that the Academy of Sci- ences was moved by it; and in 1722 the chemist Geoff roy was charged to demonstrate to the learned company that these extraor- dinary achievements were a pure fraud. In the report, which he read on the 15th of April, he said : " Since the main intention of the operators is usually to show gold or silver in the place of the minerals which they pretend to transmute, they sometimes use double crucibles or cupels, or they put salts of gold or silver in the bottom of them; they then cover the bottom with a paste made by mixing crucible-dust with gum- water or wax; doing it so that this false bottom shall seem to be the real bottom. At other times they put gold or silver dust in a hole made in a piece of charcoal; or they saturate charcoal with solutions of those metals and then reduce the mass to a powder, in order to project it upon the substances which they are going to transmute. " They use rods with hollowed ends containing in the cavities gold or silver filings, and stopped up with sawdust of the same wood. Stirring their molten matter with these rods, the sticks burn, leaving in the crucible the metal with which they have been charged. In an endless variety of ways they mix gold or silver with the substances with which they work. A small quan- tity of gold or silver will not show in a large quantity of such metallic snbstances as the regulus of antimony, lead, or copper. Salts of gold and silver can very easily be mixed with salts of lead, antimony, and mercury. Grains or nuggets of gold and silver can be inclosed in lead. Gold may be whitened with quicksilver and made to pass for tin. The collection of gold and silver from the substances with which they have been mixed may be made to pass for transmutation. "All that goes on in the hands of these people should be watched. For the aqua fortis or aqua regia which they use is often already charged with solutions of gold or silver. The papers in which they wrap their chemicals are sometimes loaded with salts of these metals ; and the pasteboards they employ may conceal such salts in their thickness. Glass has been known to come out ALCHEMIST'S GOLD. 819 from furnaces charged with portions of gold which had been ad- mittedly slipped in while it was molten. " Some alchemists have imposed on their spectators with nails half of iron and half of gold or silver. They make believe that they effect a real transmutation of half of these nails by dipping it into a pretended tincture. Nothing is more seductive at first ; but it is, after all, only a trick. The nails, which seemed to be all iron, were really in two pieces neatly soldered, the gold or silver to the iron, and washed with an iron-colored wash, that disap- peared when they were dipped into a suitable liquid. Of this character was the gold and iron nail formerly to be seen in the cabinet of the Grand Duke of Tuscany ; of like nature are those half-silver and half-iron nails which I present to this society to- day. Such also was the knife which a monk once presented to Queen Elizabeth of England, in the earlier years of her reign, the end of the blade of which was of gold ; as well also those knives, half silver and half iron, which a famous quack scattered a few years ago over Provence. It is true that they say that this last performer operated on knives that were given him, and which he gave back after a time with the ends of the blades silvered. But there is reason for supposing that the change was made by cut- ting off the end of the blade and soldering on a similar end of silver. " There have been also pieces of money and medals half gold and half silver. Such pieces were said to have been originally all silver, half of which was turned into gold by dipping them half-way into the philosopher's mixture, without the outer form or the engraved designs being essentially changed. I say that no such medal was ever all silver, but that they were in two pieces, one of silver the other of gold, so soldered together as to preserve the proper arrangement of the characters. The thing could be eas- ily done by having several silver medals of the same kind, a little worn, and making molds of them in sand for casting copies in gold. The sand would not even have to be very fine. Then let the med- als be cut exactly to rule, fitted by filing, and the complementary halves soldered together with care, to have the designs precisely correspond. Any trifling flaw could be mended with the graver. The part of the medal that is of gold, having been cast in sand, looks a little grainy and is rougher than the silver part, which was pressed; but this fault was given out to be an effect or a proof of the transmutation ; because a given quantity of silver, having a larger volume than a like quantity of gold, the silver shrunk some in changing into gold, leaving the pores or spaces that constituted the grain. The operator, besides, took pains to make the golden part a little thinner than the silver, to keep up the semblance ; and to use only as much or not quite as much 820 THE POPULAR SCIENCE MONTHLY. gold as there was of silver. A second medal was prepared in the same way. " They also took a silver medal, filed down one half of it on either side, without touching the other half, till they reduced it to about the thickness of a playing-card. Then, taking half of a medal of gold, they split it, and reducing the two parts in the required proportions, adjusted the outside parts over the silver core, preserving the proper arrangement of the designer. They then had a whole medal, half silver and half gold, but with the gold part stuffed with silver. This, they said, was a silver medal which had not lain long enough in the elixir, and had only been partly transmuted. " Half of a third medal was superficially gilded with an amal- gam of gold, and represented a piece which, having been merely dipped into the elixir, had only begun to turn. " When this game was played, the golden parts of the three pieces were whitened with mercury, so as to look as if they were all silver. To make the deception more complete, the per- former, who should' have a knack for conjuring, exhibited three genuine silver pieces that had not been tampered with, and per- mitted the audience to examine them. Taking them back, he slyly substituted his prepared pieces for them ; fixed these in his glasses, poured in as much of his elixir as suited him, and with- drew them at the lapse of the designated intervals of time. He threw them into the fire and left them there long enough to drive away the mercury with which the gold was masked. Then he took them out, looking as if they were half of silver and half of gold ; but with the difference that, in cutting the parts that seemed to be of gold, one was merely gilded on the surface, another was gold filled with silver, and the third was gold all through. " Chemistry furnished these tricksters with other most subtle means of carrying out their deceptions. It was also possible to introduce another, lighter metal into gold, which, while reducing its weight to that of an equal volume of silver, would not change its color, or separate from it in any part of the process." — Trans- lated for the Popular Science Monthly from La Nature.

The substantive can not be used without the per- sonal pronoun ; as if we could say "my heart," "thy heart," or "his heart," but not "heart" by itself. The plurals of many feminine nouns are masculine, and vice versa. In the verb "to be" or "to become," as well as in numerous other verbs, there are different plurals for men, women, animals, etc., and the latter are again subdivided according to sex.

THE commercial method of the times seems to be the merging of competing enterprises into syndicates and trusts under a single management. Naturally enough a similar tendency is be- coming manifest among producers as well as among manufactur- ing and transportation agencies. Various meetings and conven- tions among farmers of late have suggested the establishing of co-operative stores and exchanges controlled by a central bureau, which shall be the head of a gigantic farmers' pool. Indeed, the first steps to this end have already been taken in several Southern and Western States. In view of the event to which these signs point, it is not amiss at this juncture to interpose a lesson in co- operation furnished by the rise in 1887 and fall in 1889 of a large enterprise of this sort, viz., the Farmers' Alliance Exchange of Texas. It is not the purpose of this paper to discuss the expedi- ency of such commercial ventures. The intention is merely to give an historical account of the particular case under examina- tion, without even pointing a moral further than that which would suggest itself to any thoughtful mind — viz., like causes, operating under like conditions, will produce like effects. The Farmers' Alliance of the Southern States, which was con- solidated with other farmers' organizations at St. Louis in De- cember last into the Farmers' Alliance and Industrial Union of America, had its origin in Texas several years ago. One of its original purposes, according to the declaration of its constitution, was " to develop a better state financially " among its members ; and in pursuance of this purpose the Farmers' Alliance Exchange of Texas was organized. It was the first extensive business exper- iment under the Alliance movement, which had meanwhile spread over the South, and was therefore watched with considerable in- terest. At the annual meeting of the Texas Alliance, at Waco, in August, 1887, the following plan of business was adopted : 1. To incorporate the Farmers' Alliance Exchange of Texas. 2. To sell farmers' produce and to buy farmers' supplies as the farmers' agent, and to erect suitable buildings for conducting the business. 3. The capital stock to be $500,000, divided into twenty-five shares, controlled by twenty-five trustees elected by the State Alliance. 4. To raise the capital stock by assessing each member of the Al- liance two dollars, and on receipt of $50,000 to credit each share with ten per cent paid in, and like credit to be made for each sub- sequent payment of the same amount. The twenty -five trustees were elected, and a State business agency, previously in operation on a small scale, was merged into the new enterprise. From this 822 THE POPULAR SCIENCE MONTHLY. time forward for several months there prevailed among the mem- bers of the order the most hopeful and enthusiastic spirit possible to imagine, amounting to almost a universal conviction that finan- cial salvation was come. The main body of the Alliance was composed of tenant farm- ers, who as a class farm on the " third and fourth/' that is, by paying a third of the cotton and a fourth of the corn as rental for the land. They are possessed of little more than a meager house- hold and farming equipment, and are generally compelled to mortgage the growing crop to the country merchant for the year's supplies of groceries, clothing, and implements. Their hope was to escape from the country merchant, who, to say the least, does not conduct his business on the plan of quick sales and small profits. To afford such escape was equally the design of the Exchange. It may be readily perceived, therefore, that the Alli- ance was wrought to the highest pitch of excitement in contem- plation of abolishing the awful credit system which is a veritable millstone about the neck of the improvident farmer. In addition to the work of public lecturers sent out by the Alliance, several papers published in the interest of the order kept the Exchange topic red hot, while it was also a theme for discussion in the pa- pers at large, so that the general public was in a state of greater or less expectancy. In connection with the Exchange it was an- nounced by the Alliance organs and speakers that the movement would result finally — and not a very far off " finally " at that — in cotton and woolen mills, implement and wagon factories, a huge printing-house, etc. A plan was formulated also for establishing an Alliance University, with departments of law, medicine, and theology. From first to last several factories have been started, but without a single exception they have failed to reach the stage of successful operation. Immediately after the Waco meeting of the Alliance, the twen- ty-five trustees met and delegated the transaction of business to a board of seven directors, which was organized by the election of the following officers : a president, secretary, treasurer, and a gen- eral business manager. Meanwhile a charter had been procured in accordance with the foregoing plan, and the establishment was located at Dallas, in consideration of $10,000 cash subsidy, a site for buildings, and other substantial inducements. The business was opened in September, 1887, in temporary quarters provided rent free by the citizens of Dallas. The published report of the manager for that month shows an expense account of $793.91 and a cash balance of $201.40, or total resources amounting to $991.31. This was a part of the $10,000 cash subsidy, which, though never quite paid in full, was practically discharged and furnished the available capital for some time. A LESSON IN CO-OPERATION. 823 The Exchange commenced business by handling cotton and grain, and farm implements. The former were sold after the plan of a regular commission-house ; the latter were procured and fur- nished at good discounts by centering the trade direct to a whole- sale dealer, who was nominally the Alliance implement agent, but in fact was selling on his own account. It was but a short time, however, until the business was extended to the buying and sell- ing of dry goods, groceries, and general supplies. Notwithstanding the lack of capital which appears from the business manager's reports, the Exchange was complimented by the mercantile public with a fairly good credit, and may be said to have commenced life under the most favorable circumstances. The financial statement for the forty-five days ending October 31st, is as follows : Accounts and bills receivable $9,962 51 Office fixtures and furniture 202 20 $10,164 71 Liabilities. Accounts and bills payable $9,511 24 Total liabilities $9,511 24 Net capital $653 47 Losses. Expense account $312 64 Help account 1,588 82 Total losses $1,901 46 Gains. On bagging and ties $79 65 Interest and discount 1 80 Commission account 493 41 Merchandise , 62 Total gains 575 48 Net losses $1,325 98 Investment $201 40 Received from donation, etc 1,778 05 Total capital $1,979 45 Deduct net losses 1,325 98 Net capital 653 47 It will be observed that the September cash balance of $201.40 has been supplemented only by $1,778.05 " received from donation, etc.," which was mainly " donation " and little " etc." — that is to say, chiefly from the citizens' subsidy and almost nothing from stock subscription. The statement for November exhibits an increment of $1,122.40 from donation account, and practically nothing from stock, with a net capital of only $1,195.17, showing the business to be still operating at a loss. At a meeting of the directors, November 5, 1887, a novel plan of business was adopted which became the central and chief 824 THE POPULAR SCIENCE MONTHLY. feature of the institution, becoming first the means of its sudden advancement, and later the cause of its sudden suspension. It is attributed, in the minutes of the meeting, to one of the direct- ors, but probably owes its origin to the manager, who was the controlling spirit of the Exchange enterprise from its inception to the spring of 1889 — the period of his management. The plan was briefly as follows : 1. Members of each Sub- Alliance, wishing supplies on credit, to furnish a schedule of their probable needs during the year, together with a showing of their full financial responsibility, and a pledge of cotton at least three times as much as the amount of credit. 2. These several members of each Sub-Alliance to execute a joint note for the estimated amount of supplies, said note to draw interest after May 31st and to be paid November 15th. It was designed that these notes should be signed also by re- sponsible farmers (if necessary to make them bankable), who would secure themselves against loss by taking mortgages on the growing crops. In this way the country merchant was to be avoided. These joint notes acknowledged full consideration in the face, and were to be credited finally with the difference between the face and the actual credit account. The notes at first were accom- panied by a sort of bond of corresponding number, issued by the Exchange, agreeing not to part ownership with the notes ; but, upon the failure of the order during November and December to pay in any considerable amount of the capital stock, the available donation being then about exhausted, the notes were, by order of the board of directors in January, used as collateral security in borrowing money. The business manager's report for the month ending January 31st showed $4,157.36 increase of capital during the month, or a total of $5,247.93. The months of January, February, and March constituted a period of great activity. The country was alive with lecturers in the joint employ of the State Alliance and the Exchange ; " The Southern Mercury," organ of the order, had an extensive circulation, and the Exchange was issuing a semi- monthly circular letter containing private advice, discounts, etc. During this time the total capital was increased to $20,215.38 ; the amount of joint notes reached $200,974.88, on which goods had been advanced to the amount of $108,371.06. An extract from the business manager's report for the month of March shows " the beginning of the end," the first embarrass- ments that soon culminated in a serious, not to say fatal, collapse : ' The business manager spent the whole of the month of March in trying to negotiate banking arrangements whereby a A LESSON IN CO-OPERATION. 825 loan could be effected at a reasonable rate of interest, to provide funds to purchase goods with which to supply the contracts ac- cepted by the committee of acceptance ; but all the efforts made were unsuccessful, and tended to produce the conviction that those who controlled the moneyed institutions of the State either did not choose to do business with us, or they feared the ill will of a certain class of business men who consider their interests antagonistic to those of our order and corporation. At any rate, be the causes what they may, the effort to borrow money in a suf- ficient quantity failed." The month of April showed an increase in capital, from stock paid in, of $1,526.36. During the month of May maturing obliga- tions failed to be met, notes of the Exchange went to protest, and general disaster followed, amounting almost to a total suspension of business. During all this time the most hopeful statements were made by the manager to the public, and the general frater- nity were induced by official utterances to believe that the troubles of their business were precipitated by a combination of bankers and wholesale merchants to crush it out. A meeting of the State Alliance Executive Committee was called, and, after a few days of examination into the business at Dallas, the following call, signed by the seven directors, was issued : Members of the Farmers' Alliance of Texas: Brethren : Grave and important issues confront us to-day. Unjust combina- tions seek to throttle our lawful and legitimate efforts to introduce a business sys- tem more just and equitable than is now prevailing. ... In order that the proof of the existence of this combination may be submitted to you, and that a full, free conference may be had with the brethren, it is most earnestly recommended that a mass meeting be held at the court-house in each county of the State on the sec- ond Saturday in June, at which meeting documentary evidence disclosing facts of ^ast importance will be laid before you, and a plan for your consideration and adoption. . . . In addition to this, there was issued about the same time a secret circular, signed by the officers of the Exchange, which is so violent in language as to almost merit the adjective "revolu- tionary." The circular is too long for reproduction here, but the main points may be summarized as follow : 1. There was from the first a hidden, underhanded, masked opposition to the Exchange. 2. That Dallas bankers, wholesale merchants, implement dealers, and manufacturers entered into a combination to crush the Exchange ; that the bank- ers refused to lend the Exchange money upon any terms or any security, and tried to force them to buy through jobbers. 3. That the Dallas combination "kept the mails full and the wires red hot" to prevent the Exchange from get- ting money at Fort Worth, Houston, Galveston, and New Orleans. These utterances indicate the bitterness of feeling incited by the Exchange management and- the officers of the State Alliance. 8z6 THE POPULAR SCIENCE MONTHLY. While the circulars were condemned by a few conservative spir- its, and were subsequently regretted, probably, by all reasonable men in the order, at that time they were not publicly disputed except by outside parties. "The Texas Farmer," organ of the Texas State Grange, went to the trouble of interviewing promi- nent bankers and business men in Dallas, who uniformly denied the existence of any such combination, and affirmed their good- will for the Exchange, attributing its failure to lack of busi- ness management. From the publication of these circulars, in May, to the 9th of June, the Alliance was in a state of violent ex- citement. In addition to the circulars and other publications, lecturers covered the entire State, and, by every possible argu- ment and appeal, urged the members to take stock and save the business from final ruin. The effect was to raise only little less than $30,000, though subsequent fruits of the same canvass in- creased that amount to nearly $50,000. The statement for June shows a total capital invested of $56,409.26. This call on the 9th of June, 1888, which became a memorable day in Alliance history, forcibly illustrates the weakness of such financial schemes as depend on popular subscriptions, or per capita assessments, with no other power of collection than the force of fraternal obligation. The membership of the Alliance in Texas had been frequently estimated by Alliance speakers and writers at 250,000, though it probably never reached more than half that number — if more, it all the more strongly illustrates the point. In speaking of the resources of the Alliance business, it was common with leaders to say that unlimited sums could be raised on call. For instance, an assessment of one dollar per capita would bring in, within thirty days, $125,000 (or $250,000, according to the highest estimate of membership). Here was a case of prime importance in which it was urged that not only the salvation of the business but the freedom of the farmer was at stake, and yet the total subscriptions, first and last, did not exceed $50,000. Notwithstanding the disaster impending in the early spring, the board of directors at their March meeting entered into a con- tract for a building, to cost $34,117, which was in due time com- pleted, though never one fourth paid for, and in April opened a branch Exchange in Belton, Texas. The Belton business re- ceived substantial inducements from citizens amounting to about $10,000. It is unnecessary to further follow the business in detail. The June rally failed to raise the needful amount of funds to make the Exchange easy. Extensions were secured from time to time, and efforts were constantly made to raise the capital stock, but without material success. The Exchange never recovered from the wild A LESSON IN CO-OPERATION. 827 and extravagant methods of its first winter, and in the summer and fall of 1888 it was further crippled by attacks of "The Southern Mercury/' the State Alliance organ, on its business management. This caused internal dissensions which threatened at one time to disrupt the order, creating two bitter factions, which for a long time refused to be reconciled. Early in 1889 the business manager of the Exchange resigned, and a new one was elected in his stead. Meanwhile there had been a change in the editorial management of the " Mercury," and the spirit of true fraternity soon reasserted itself, the order becoming again firmly cemented, though it had lost materially in members. However, the better part remained, and the Alliance has since been happily progressing in all that relates to social and economic education. The management of the Exchange during 1889 was conserva- tive and judicious, and, under other circumstances, he would doubtless have made it a successful enterprise , but it was too heavily encumbered, and the confidence of the order in it had been sacrificed. His report to the State Alliance, August, 1889, is as follows : Resources. Exchange building, Dallas $70,000 00 Exchange building, Belton . . . 12,000 00 Exchange building, Longview . 9,000 00 Live stock, Henrietta 7,500 00 Merchandise, all points 50,238 00 Accounts and bills receivable, estimated good 39,210 00 $179,848 00 Liabilities. Bills payable on merchandise . $44,704 42 Bills payable on buildings 29,300 00 Accounts payable 1,285 81 $75,290 23 Present net worth 104,557 77 $179,848 00 Cash received and paid out. Amount paid on old indebtedness $34,103 43 Amount received from sale of lands $14,800 00 Amount received from capital stock 5,276 50 Merchandise sales and collections 14,026 93 $34,103 43 $34,103 43 Report made to directors in January showed the mercantile indebtedness to be $46,000. The real fact is that it was $78,817.85. The State Alliance, in August, 1889, passed a resolution provid- ing for a voluntary trust fund of $75,000, or enough to discharge the entire indebtedness of the Exchange, but not to be used until raised in full. The trust fund never reached a third of the re- quired amount, and in December last the Exchange building at Dallas was sold under mortgage for $35,000. Immediately there- after the manager proceeded to wind up the affairs of the Farm- ers' Alliance Exchange of Texas. To recapitulate : The Exchange commenced to do business 8 z8 THE POPULAR SCIENCE MONTHLY. without capital, depending on donations and assessments, with no power to enforce collection. Instead of confining its opera- tions to buying and selling as the farmers' agent, it attempted to take the place of the country merchants, and to furnish supplies on credit to all the farmers of Texas. To do this successfully would require millions instead of thousands. The reason the banks refused to lend money to the Exchange in March, 1889, was neither opposition to the Exchange nor undue friendliness to the jobbers, but plain business prudence. The Exchange was doing a larger business than its capital warranted ; the joint notes used as collateral security were represented by accounts from twenty-five to seventy-five per cent less than the face of the notes, and while innocent purchasers could be protected in the courts, still litigation is a resort which every prudent business man tries to avoid ; some of the joint notes were offset by bonds agreeing not to part ownership, while as a matter of fact they were placed in serious jeopardy by being put up as collateral security for ex- tensive loans. The wisdom of these precautions was demonstrated in the final outcome of the Exchange's management. In October last the representatives of the trust fund, which reached about $17,000, perceiving that it would be inadequate for the ends sought, met at Dallas and placed it in the hands of the manager, instructing him to save such part of the Exchange as might be possible. Since the sale of the building there has been organized a new corporation, composed of Alliance members rep- resenting the trust fund ; and this new corporation, known as the Farmers' Alliance Commercial Agency, has purchased the Ex- change building, and designs carrying on a general buying and selling agency. It is to be hoped that the new enterprise will be more successful than the old one was. According to Oudeman's review of parallax investigations, the distance of forty of the fixed stars has been approximately determined. The disproportion be- tween this number and the number of stars of which we know nothing is so great, says Mr. A. M. Clarke, that general conclusions seem discredited beforehand, and negative ones can have no weight. But it is evident that the largest stars are not always those nearest to the earth. Seven of those whose distances have been as- certained are invisible to the naked eye, while one is nearer than Sirius, and all are nearer than Capella, Vega, Arcturus, or CaDopus. A further conclusion may be deduced that the disparities between the stars are enormous. " A farthing rush-light is not more insignificant compared with the electric arc than a faint star compared with a potent sun. Sirius emits 6,400 times as much light as the ninth-magnitude star 11,677 Argelander-Oelzen ; and our own sun is nearly as much inferior to Arcturus. Inequalities of the same order appear between the members of revolving systems ; as, for instance, Sirius shines like four thousand of his companions." INTELLIGENCE OF SQUIRRELS. 829 INTELLIGENCE OF SQUIRRELS.* By Dr. T. WESLEY MILLS, PROFESSOR OF PHYSIOLOGY IN MCGILL UNIVERSITY. TTNTIL recently, the habits of animals seem to have been con- \-J sidered simply as interesting manifestations of 'their life, but without any special reference to their relations to the intel- lectual part of the creatures concerned. But unless we assume that animals are devoid of mind and true intelligence — an ex- treme and untenable position — there must be a possible science of comparative psychology, as there is of comparative anatomy and physiology. The study of animal intelligence is possible, inter- esting, and important, whether we regard man as derived from some lower form, and his intellectual as well as his physical being the result of evolution ; or whether we consider that man stands wholly apart in origin either as to body or mind. In the latter case, the study of the lower forms of mind affords a useful con- trast with its highest development as seen in man ; in the former, we aim at the construction of a ladder by which we may climb from the simplest manifestations of consciousness to the highest performances of the most gigantic human intellect. I have selected the study of squirrel psychology as the subject of this paper, because so little seems to have been written on the subject; because these animals are open to the observation of every one ; and chiefly because I have been able to give special attention to them myself. Their habits will be considered princi- pally, but not exclusively, from the psychological standpoint ; and I shall apply the comparative method, making such refer- ences to the habits and intelligence of other rodents as seem to throw light on those of the squirrel. While some attention has been paid to other species of squirrels, my studies have been chiefly on the ground squirrel (Tamias Lysteri) and the red squirrel (Sciurus Hudsonius). These species, in many respects, form a contrast to each other. The chipmunk, chipping squirrel, or hackee, has his abode under- ground in a specially constructed burrow; the red squirrel, or chickaree, lives in nests in trees ; and the intelligence of the latter seems to be altogether of a much higher order than in the ground squirrel. This was abundantly illustrated in my experiments with an ordinary wire rat-trap having a spring door. The trap was scarcely laid down near the haunts of the chipmunk before one entered it, in fact before my eyes ; and there was never any difficulty in securing as many as were wanted. On several occa- * Part of a paper communicated to the Royal Society of Canada. 830 THE POPULAR SCIENCE MONTHLY. sions, when one had escaped in the room, on placing a small apple in the cage, the creature re-entered it almost at once. Very different was it with the red squirrels ; at first they en- tered the trap, hut not afterward. They approached it, some- times two or three together, ran round it on the upper rail of the fence on which it was placed, or sat on top of it — in short, did everything but enter it — all the while seeming to enjoy the whole greatly. Having secured a couple of ground squirrels in the manner described, I kept them under observation for the period during which they survived, viz., one for about a month and the other for between two and three months. From the first, one of them seemed to take more kindly to his new surroundings than the other; one appeared shy and dull, while his fellow seemed as happy as any chipmunk might be. They were captured in Sep- tember, and it has often occurred to me that their habit of hiber- nation had something to do with the behavior of the one, though we should expect that, in such a matter, both would be equally or considerably affected. The degree to which, while retaining their original habits, the latter became modified in confinement, fur- nished me with an interesting study, and suggested many prob- lems. My experience does not agree wholly with that of Audu- bon and Bachmann, who say, in their " Quadrupeds of North America," " We are doubtful whether this species can at any time be perfectly tamed." The one of my chipmunks that sur- vived longest became in a short time so tame that he would eat from the hand, and even looked to be fed in this way. True, any noise, or any unusual movement, might startle the creature, when he would make the quick dart away so characteristic of the spe- cies in the wild state. But from this he very quickly recovered, and the tendency to be thus frightened grew less and less. The authors referred to also state that " they appeared to have some aversion to playing on a wheel, which is so favorite an amuse- ment of the true squirrels." This does not at all agree with my observations; for though at first my chipmunk was apt to be startled when he found the revolver of his cage moving on his entering it, he soon got used to it, and delighted in it as much as any squirrel could — in fact, he used it by night and by day, mani- festing an ability to control it which speaks much for the readi- ness with which such animals adapt themselves to new and diffi- cult movements, and which shows how highly developed those parts of the brain must be which are concerned in the balancing and kindred functions. I may here correct another statement of the same authors. They maintain that squirrels do not lap fluids as the dog and cat. From repeated observations I know this to be an error, at least so far as the ground squirrel is concerned. INTELLIGENCE OF SQUIRRELS. 831 It has usually been assumed that squirrels, and indeed most rodents, feed wholly on vegetable food, and that in those instances in which the contrary has been observed there was evidence of a perverted or morbid appetite. Audubon and Bachmann, however, state that the flying squirrel (Pteromys volucella, Des.) has been caught in traps baited with meat. A number of writers,* espe- cially within the past few years, have drawn attention to flesh- eating habits in several rodents, mostly under peculiar circum- stances. Some interesting questions arise in this connection: 1. In how far is any rodent carnivorous, when abundance of all the different kinds of vegetable food that the animal uses is at hand ? 2. What is the relation between confinement and altered appetites ? 3. In how far are such altered appetites evidence of morbid or perverted conditions, and in how far simply the expres- sion of physiological needs ? The whole subject, I am inclined to think, might be placed on a broad and sound physiological foundation ; but, before that can be done, many accurate observa- tions are required, and possibly also many series of experiments. If we may judge by the common house rat, rodents possess un- usual plasticity as to feeding and other habits, and not less as regards their mental life. I found that my chipmunk would take a great variety of foods, though the experiment of feeding with meat was not tried. He drank milk greedily. There is one peculiar habit, interesting from a physiological point of view, to be observed in squirrels in confinement. A writer in " Nature " (vol. x ) says, " I have noticed that whenever it [the squirrel] cleans itself, after licking, it sneezes violently three or four times into its fore-paws, then rubs them thus damped over its fur." And this writer raises the question as to whether this habit, which he believes voluntary, was confined to squirrels. He does not mention what sort of a squirrel his own was ; but I have noticed this behavior as of most frequent occurrence in my caged chipmunk. It seems to me, on the whole, most natural to con- sider it a voluntary act of the same character, and possibly for a similar purpose, as cleaning the throat in the human subject, or perhaps even blowing the nose. And I am the more inclined to believe that it is voluntary, from the account given of the flying squirrel, as observed by Prof. G. H. Perkins and recorded in " The American Naturalist" (vol. vii). This writer states that on one occasion his squirrel lapped some ink, but shortly afterward manifested disgust and indulged in violent sneezings. Under these circumstances it is difficult to understand, by anything in our own experience, how the act could have been reflex. Speaking of the relative intelligence of squirrels, this writer says, " I am inclined to believe that the flying squirrel does not * " Science," vol. viii ; " Canadian Naturalist," vol. iii. 832 THE POPULAR SCIENCE MONTHLY. possess as much intelligence as the gray or red or some other spe- cies." From the entire account of the flying squirrel given by Prof. Perkins, I should suppose that the intelligence of this species and that of the ground squirrel are about on a par — the explana- tion of which will be considered later. A question of much interest to the naturalist and psycholo- gist, it seems to me, is the following, viz., to what extent the intel- ligence of animals that hibernate has been modified by this pro- cess, and in what directions. With regard to hibernation, so far as the squirrels are concerned, there seems to be great dearth of accurate observations; in fact, the same remark applies to the whole subject of hibernation, one of the most interesting in the whole realm of physiology. A number of observations are to be found scattered through the literature, but they are fatally lack- ing, in most cases, in precision of observation and accurate rec- ord of dates. From a short but valuable paper on " The Ameri- can Chipmunk," in " The Popular Science Monthly " (vol. vii), by Dr. C. Abbott, we are led to believe that the ground squirrel spends some time in his burrow before hibernation begins, and that the food laid up is consumed in part before the winter torpor sets in, and more especially in the spring before a fresh supply is obtained in the usual way. Concerning the winter habits of other species, I have been able to learn nothing from any quarter that definitely settles the question as to whether they hibernate or not. Audu- bon and Bachmann (loc. cit.) state that as much as one bushel and a half of nuts has been found in a single hollow tree occupied by a chickaree or red squirrel. They also state that this species may have several hoards. From different remarks dropped by these writers, from what I have myself observed, and from the state- ments of Dr. R. Bell, I am inclined to the belief that the red squirrel and some other species do not regularly hibernate the whole winter through. But whether they hibernate at all, in the true sense of that term ; whether they have short periods of hiber- nation, followed by intervals of consciousness, during which they feed ; whether they remain in a condition of partial torpor, with slowing of all the vital processes, and yet not in absolute insensi- bility and with cessation of respiration, etc. — all these questions seem to be as yet wholly undecided. It has long been known that many cold-blooded animals hiber- nate and, under altered conditions, sestivate ; it is further believed that among warm-blooded animals, besides bats, many rodents and some allied animals hibernate. But, when the matter is looked into carefully, it is found that the term " hibernation " has been used in a loose and very plastic sense by different authors. It is highly desirable, therefore, that writers should state exactly to what extent the animal they describe as " torpid," " hibernat- INTELLIGENCE OF SQUIRRELS. 833 ing," or " in winter-sleep/' deviates functionally from the normal ; also, that the exact time of the observations be recorded. There is a certain amount of evidence that even birds, representing the highest type of activity, may possibly hibernate ; and that many animals, not usually thus affected, may become so under exceptional circumstances — indeed, that man himself, owing to peculiar states of the nervous system, may pass into a condi- tion ("trance") having much in common with the hibernation of lower animals. I think it is very probable that, when the matter has been fully investigated, all degrees of cessation of functional activity will be found represented, from the normal daily sleep of man and other animals, to the lowest degree of activ- ity consistent with the actual maintenance of life. The flying squirrel is nocturnal in habits and exceedingly active, even in confinement, as Prof. Perkins (loc. cit.) has shown ; but during the daytime it seems not to be correspondingly quick — in a condition, in fact, resembling somewhat that of a hibernating animal. The " diurnal hibernation " of the bat is not to be forgotten. I noticed that my chipmunk invariably, after feeding, tucked his head down and assumed a more or less ball-like form highly suggestive of a tendency to hibernation. There are many questions that arise in connection with this subject, one of which bears directly on the subject of comparative psychology: How and to what extent is the intelligence of animals influenced by hibernation? It may be considered pretty clear that both the ground squirrel and the flying squirrel hibernate, and these are certainly among the lowest — perhaps are actually the lowest — in intelligence of the whole tribe. "We know that struggle among higher animals develops mental adaptation and other forms of intelligence, and it is rational to suppose that those spe- cies of squirrels that do not hibernate throughout the winter, but endeavor to prevail over their surroundings, as well as to adapt themselves to them, should be more intelligent than those spend- ing a large portion of each year in inactivity. My chipmunk, during its captivity, under certain circum- stances, kept to his original habits — e. g., when a single nut was given him he would eat it immediately, but if several were pre- sented at once he would hide them one by one in a corner of his cage, or, if sufficiently small, pack them away in his cheek-pouches. He did the same with cereal grains. When cotton wool or web- like material was placed in the cage, he manipulated it a good deal, but finally made a bed of it, in which he buried himself out of sight. Within the last ten years attention has been called to " sing- ing " in certain rodents, especially mice ; but from numerous ref- erences in the literature it appears that " singing," or something vol. xxxvi. — 53 834 THE POPULAR SCIENCE MONTHLY. analogous to it, has been noticed in a large number of rodents.* The well-known note of the chipmunk, from which it has derived its name, is the only one I have heard from it. After studying a colony of red squirrels for some weeks last summer, I came to the conclusion that they have a capacity of vocal expression much greater than is commonly believed. Their usual " barking," or trilling, seems to be the commonest, the most instinctive, and not largely expressive of anything beyond general satisfaction ; but I found that, under excitement, there were many other tones, asso- ciated with great complexity of emotion, which I am not prepared to analyze, but which there can be little doubt the creatures them- selves employ as a means of intercommunication. Under marked excitement, as the result of repeated interferences, I have heard a red squirrel so mingle tones of a musical kind that a stranger, arriving on the spot, would certainly have been deluded into the belief that he was listening to some bird, or rather to an excited pair of birds. The musical character of this combination, together with its continuity and complexity, would perhaps justify the designation " song." One of the writers on musical mice refers to their singing but little in certain instances, except when excited, which is a point of analogy with the chickaree. It would appear, therefore, that it is likely that, throughout the order Rodentia, a genuine musical appreciation and executive capacity exists, and in some instances in a very high degree ; and that apart from this there is also considerable ability displayed in the expression of states of emotion, at least, by vocal forms. Mani- festly, the degree to which animals can express their psychic states — and especially in vocal forms — is a matter of the greatest importance, and I have already elsewhere ("Popular Science Monthly," March, 1887) expressed my conviction that animals have a power of communicating with each other, altogether be- yond what has been generally surmised. The subject is beset with great difficulties, and calls for the closest observations. The reviewer, in "The Academy," of Dr. Oliver Lodge's "Modern Ideas of Electricity" emphasizes the promise implied in the present state of scientific research and mathematical investigation that some great step forward is about to be made. "It is because the scientific world," he says, "knows itself to be on the verge of discoveries as to the nature of the ether, more far-reaching possibly than the discovery of the mode of gravitation, that it lives in a state of suppressed excitement, which hinders it sometimes from further progress or from recognition of the relative importance of recent work " ; and lie hints that the century wbich produced Darwin is now ripe for almost a greater genius than he. A similar tone is sounded in Prof. Lodge's book. * See especially " Nature," vol. xv, " Popular Science Monthly," vol. i, and " The Ameri- can Naturalist." SKETCH OF DAVID RITTENHOUSE. 835 SKETCH OF DAVID RITTENHOUSE. 66 A S a. citizen of Pennsylvania/' says William Barton, in the -£j- preface to his "Memoirs of the Life of David Ritten- house"; "as an inestimable public and private character; as a distinguished son of science, of great probity and extensive use- fulness in society — in all these points of view, the history of Dr. Rittenhouse may be contemplated as holding a relationship with almost every object connected with science and art in his day that could in any way contribute to the well-being of mankind in general and his native country in particular." He, in fact, ac- quired a fame in the period of the infancy of American science, the nature and extent of which can hardly be realised in this day ; and his gifts, then regarded as extraordinary, were always freely placed at the service of the public. David Rittenhouse was born in Roxborough Township, near Germantown, Pa., April 8, 1732, and died in Philadelphia, June 26, 1796. He was descended from a family of paper-makers resid- ing at Arnheim, Guelderland. His great-grandfather, William Rittenhouse, a Mennonite preacher, came from Holland with his family in 1687-'88 ; was the first Mennonite minister in Pennsyl- vania ; and established the first paper-mill in this country, at the spot where David was born. David was early put to work on the farm, and was plowing at fourteen years of age. An uncle dying had left him a chest of tools and a few books on arithmetic and geometry, with some manuscript mathematical calculations. These furnished pala- table food to his mind, and his biographers tell of his having cov- ered the handle of his plow and the fences around the field with his workings of the problems which they set before him. As the uncle mentioned above was his mother's brother, it is inferred that he inherited his genius from his mother's side. His mechani- cal talent was shown in his construction of a complete water-wheel in miniature when eight years old, a wooden clock when seventeen, and a clock with metallic works at a later age. His father was not disposed at first to favor the youth's tastes, but eventually he fur- nished him with money enough to buy a set of clock-making tools ; and David built a workshop at Norriton, whither the family had removed, where he carried on the clock-making business for several years. He at the same time pursued his studies so diligently that he impaired his constitution, and contracted a pain that afflicted him all his life. Astronomy appeared to be his favorite study ; and he was interested in optics and mechanical science. He dis- covered himself, independently, the method of fluxions, of which, in his imperfect knowledge of what Newton and Leibnitz had 836 THE POPULAR SCIENCE MONTHLY. done, he believed himself to be the originator ; and mastered the English translation by Motte of Newton's " Principia." The acquaintance which he formed in 1751 with Thomas Bar- ton, who afterward married his sister, had an important influence in shaping his career. Rittenhouse, according to William Barton, " possessed a sublime native genius ; which, however, was yet but very imperfectly cultivated for want of indispensable means of extending the bounds of natural knowledge." Barton had enjoyed these means, and had acquired the reputation of being a man of learning. He found Rittenhouse's society profitable, and Ritten- house found his equally so. Barton aided Rittenhouse greatly by helping him to the books he needed. Partly through his instru- mentality a circulating library was established at Norriton ; and he bought books for Rittenhouse when he went to Europe. Mr. Rittenhouse was called upon in 1763 to determine the initial of the boundary-line between Pennsylvania and Maryland, his particular duty being defined to be to ascertain and fix the " circle to be drawn at twelve miles' distance from New Castle, northward and westward, with the beginning of the fortieth de- gree of north latitude," etc. The work was an arduous one, and involved going through a number of tedious and intricate calcu- lations. It was performed in a satisfactory manner, for which acknowledgment was made in the shape of extra compensation, and with instruments to a large extent of Rittenhouse's own making ; and his observations were accepted without change by the official astronomers, Mason and Dixon, when they took charge of the work. He was afterward appointed to a similar work in 1769, by the commission to settle the boundary between New York and Pennsylvania. Among his scientific studies at this period were the investigation of variations in the oscillations of the pendulum under changes of temperature, with the device of a plan for compensation, and the construction of what he called a metalline thermometer. This instrument was so made — on the principle of the expansion and contraction of metals under varia- tions of temperature — that the degrees of heat and cold were in- dicated by the movements of an index moving along a graduated semicircle. It was adapted, in form and size, to be carried in the pocket. He discussed the compressibility of water in the light of an experiment that had been reported to the Royal Society, and observed, in a letter to Mr. Barton, that, although the experiment did not please him, he did not doubt the fact ; for, "if the particles of water were in actual contact, it would be diffi- cult to conceive how any body could much exceed it in specific gravity ; yet we find that gold does, more than eighteen times." We find him also at this time (1767) indulging in some amusing speculations on the possibility of a man's moving the world. SKETCH OF DAVID RITTENHOUSE. 837 Some one having published the result of calculations he had made respecting the fulfillment of Archimedes's famous dictum on the subject, Mr. Rittenhouse gave the result of his own computa- tions, which was that " the force wherewith a man acts when he lifts a weight of two hundred pounds, if applied without inter- mission for the space of one hundred and five years, is sufficient, without any machinery, to move the earth one inch in that time ; and it must, from the velocity received by that force alone, con- tinue forever after to move at the rate of one inch in fifty years." The first calculator had computed that twenty-seven billions of years would be required to accomplish the movement. Mr. Rittenhouse's reputation as an astronomer became con- spicuous, and his name, according to Mr. Barton, acquired a celebrity even in the Old World, " of which his early but now much-increased fame in his native country was a sure presage." A great bound was given to his fame by his construction of an orrery, or apparatus for illustrating the planetary motions, and by the conspicuous part which he took in the observations of the transit of Venus of 1769. The design of the orrery is indicated in the correspondence with Mr. Barton in 1767, in the course of which Mr. Rittenhouse says : " I did not design a machine which should give the igno- rant in astronomy a just view of the solar system; but would rather astonish the skillful and curious examiner by a most accu- rate correspondence between the situations and motions of our little representatives of the heavenly bodies and the situations and motions of those bodies themselves. I would have my orrery really useful by making it capable of informing us truly of astro- nomical phenomena for any particular point of time, which I do not find that any orrery yet made can do." This instrument was bought before it was finished for Prince- ton College. The trustees of the College of Philadelphia had also been bargaining for it, and were disappointed over the turn the affair had taken. Mr. Rittenhouse had made a saving clause in his bargain in favor of the College of Philadelphia, in agreement with which he began another orrery for that institution. " This," he said, " I am not sorry for, since the making of the second will be but an amusement compared with the first ; and who knows but that the rest of the colonies may catch the contagion ? " The sum of two hundred pounds was obtained toward paying for the instrument by means of lectures on astronomy delivered by Rit- tenhouse's friend, the Rev. Dr. Smith, Provost of the College of Philadelphia, concerning which the Rev. Dr. Peters wrote, " The doctor in his introductory lecture was honored with the principal men of all denominations, who swallowed every word he said with the pleasure that attends the eating of the choicest viands, 838 THE POPULAR SCIENCE MONTHLY. and in the close, when he came to mention the orrery, he over- excelled his very self." The members of the Assembly of Pennsyl- vania took a view of the orrery, and, " being of the opinion that it greatly exceeds all others hitherto constructed, in demonstrating the true Situations of the celestial Bodies, their Magnitudes, Mo- tions, Distances, Periods, Eclipses, and Order, upon the principles of the Newtonian System," voted the constructor three hundred pounds in consideration of his mathematical genius and mechan- ical abilities, and appointed a committee to agree with him for a new orrery for the use of the public. This purpose was not car- ried out. Mr. Rittenhouse became engaged in public enterprises, which occupied his time till the beginning of the Revolution, when all other interests were suspended. The praises which were bestowed upon Mr. Rittenhouse for his orrery were extravagant, and seem now even absurd ; but noth- ing, perhaps, can more clearly illustrate the infantine condition of American science at the time. Mr. Barton, by way of emphasizing the assertion that the skill and accuracy he displayed in the construction of his mathemat- ical and astronomical instruments were not surpassed by similar works of the most celebrated British mathematicians, remarks that " his profoundness in astronomical science and his wonderful ingenuity, manifested in the construction of his orrery, leave him without a rival in the twofold character of an astronomer and mechanic." Dr. Jedediah Morse, in his " Geography " (1789), noticing some of the more prominent productions of scientific in- genuity and skill in America, observed that " every combination of machinery may be expected from a country, a native son of which, reaching this inestimable object in its highest point, has epitomized the motions of the spheres that roll throughout the universe." Mr. Thomas Penn, of London, was surprised that the instrument could have been executed in Pennsylvania. Joel Bar- low wrote, in the " Vision of Columbus " : See the sage Rittenhouse, with ardent eye, Lift the long tube and pierce the starry sky; Clear in his view the circling systems roll, And broader splendors gild the central pole; He marks what laws th' eccentric wand'rers bind, Copies Creation in his forming mind, And bids beneath his hand in semblance rise, With mimic orbs, the labors of the skies. Thomas Jefferson, the sober statesman, Mr. Rittenhouse's suc- cessor as President of the American Philosophical Society, wrote, in his " Notes on Virginia," in refutation of the Abbs' Reynal's assertion that America had " not produced one able mathemati- cian, one man of genius in a single art or science " : " We have SKETCH OF DAVID RITTENHOUSE. 839 supposed Mr. Rittenhouse second to no astronomer living ; that in genius lie must be the first, because he is self-taught. As an artist he has exhibited as great a proof of mechanical genius as the world has ever produced. He has not, indeed, made a world ; but he has by imitation approached nearer its Maker than any man who has lived from the creation to this day." A committee of thirteen persons was appointed by the Ameri- can Philosophical Society early in 1769 to view the transit of Venus, which was to occur on the 3d of June — a phenomenon which had been scientifically observed only twice before. This committee was divided into three, for observation at three sta- tions— Philadelphia, Mr. Rittenhouse's home at Norriton, and the lighthouse near Cape Henlopen. Three other observers were as- sociated with Mr. Rittenhouse at Norriton. An observatory was furnished, and the preparations and calculations preliminary to taking the observations were made by Mr. Rittenhouse. Some instruments were bought for the other stations. For Norriton a reflecting telescope was furnished by Mr. Maskelyne, Astronomer Royal at Greenwich — afterward given to the Philadelphia College — an astronomical quadrant by the Earl of Stirling, of East Jer- sey ; and an equal-altitude instrument, a transit telescope, and a timepiece were made by Mr. Rittenhouse. The results of the ob- servations were communicated to the American Philosophical Society, and a report of them was furnished to Mr. Maskelyne, who declared that they seemed excellent and complete, and did honor to the gentlemen who made them and to those who pro- moted the undertaking. The whole affair, in fact, gave the ob- servers great credit abroad, and was regarded as promising well for the future of American science. The importance of the obser- vation may be judged from the fact that it furnished one of the elements for verifying the great astronomical unit — the earth's distance from the sun. On the 9th of November following this observation a transit of Mercury — the fourth ever witnessed — was observed at Norriton by Mr. Rittenhouse and his fellow-astronomers, and a report on the subject was filed with the Philosophical Society. Shortly after this the difference of the meridians of Norriton and Phila- delphia was determined by a committee, of which Mr. Rittenhouse was one, at the request of Mr. Maskelyne, who wished to connect the observations of the longitude of Norriton with those made by Messrs. Mason and Dixon in the course of measuring the degree of latitude. About this time a scheme was started by Dr. Smith to induce Mr. Rittenhouse to remove to Philadelphia. Recommending him for appointment as a trustee of the Loan Office, then before the Assembly, Mr. Smith represented to the Speaker that he " ought 840 THE POPULAR SCIENCE MONTHLY. to be encouraged to come to town, to take a lead in a manufact- ure, optical and mathematical, which never had been attempted in America, and drew thousands of pounds to England for instru- ments, often ill-finished ; and it would redound to the honor of Philadelphia to take a lead in this, and of the Assembly to en- courage it." The proposition was received enthusiastically, and the whole house rose to vote for Mr. Rittenhouse, one of the mem- bers exclaiming, " Our name is legion for this vote." The Assem- bly adjourned, however, without passing the bill, although Mr. Rittenhouse was afterward appointed to the position for which he was named in it. He removed to Philadelphia, on his own account, in the fall of 1770. The next scientific investigation in which he appears to have been engaged was the observation of the comet of 1770, of which he calculated the elements, and com- municated the results to the American Philosophical Society. We afterward find him, with several other gentlemen, making experiments on the electric eel for the purpose of ascertaining the origin of the shock which the animal emits on being touched. From this time on, Rittenhouse was to a considerable extent engaged in works in the service of the public, to some of which he was called in consequence of his scientific ability and mechanical skill, to others commended by his character as a citizen and his integrity. He was given charge of the State-House clock; ap- pointed to survey the lands between the Susquehanna and Dela- ware Rivers ; to superintend the improvement of the Schuylkill ; and to determine the northwestern extremity of the boundary between New York and Pennsylvania. In 1775 the American Philosophical Society presented to the Pennsylvania Assembly a plan for the erection of an observatory under State control, with Mr. Rittenhouse as " public astronomi- cal observer " ; describing him as " a gentleman whose abilities, speculative as well as practical, would do honor to any country. . . . Under his auspices the work could now be undertaken with the greatest advantages ; and others may be bred up by him, to prosecute it in future times ; but, if the present opportunity is neglected, perhaps whole centuries may not afford another. To rescue such a man from the drudgery of manual labor, and give him an occasion of indiilging the bent of his genius with advan- tage to his country, is an honor which crowned heads might glory in ; but it is an honor also, which it is hoped, in the case of a native, Pennsylvania would not yield to the greatest prince or people on earth." The Revolution came on, and the scheme was not carried out. In view of that crisis, Mr. Rittenhouse was commissioned to prepare molds and have iron clock-weights cast, to be exchanged with the people for their leaden ones ; as engineer to the Com- SKETCH OF DAVID RITTENHOUSE. 841 mittee of Safety, to arrange for casting cannon ; to view a site for the erection of a Continental powder-mill; to conduct experi- ments for rifling cannon and musket balls ; to devise a method of fastening a chain for the protection of the river ; to superin- tend the manufacture of saltpeter, and to locate a magazine for military stores. He was a member of the Committee of Safety in April, its vice-president in August, and its presiding officer in November, 1776. In 1776 he was a member of the Assembly from Philadelphia, and a member of the first Constitutional Conven- tion of Pennsylvania ; a member of the Board of War ; and one of the Council of Safety, which had absolute powers. He was the first State Treasurer of Pennsylvania, from 1777 to 1789, when he declined to serve any longer. He was the first Director of the United States Mint, serving for three years from 1792; and he was called upon on several occasions to serve on commissions for the adjustment of boundaries. In connection with these public employments we find a curious letter from Mr. Jefferson to Mr. Rittenhouse, written in 1778, protesting against his wasting his abilities on affairs of state. " I am satisfied," he says, " that there is an order of geniuses above that obligation [to conduct govern- ment], and therefore exempt from it. No one can conceive that Nature ever intended to throw away a Newton upon the occupa- tions of a crown. It would have been a prodigality for which even the conduct of Providence might have been arraigned, had he been by birth annexed to what was so far below him. ... I doubt not there are in your country many persons equal to the task of conducting government ; but you should consider that the world has but one Rittenhouse, and that it never had one before." Mr. Rittenhouse was Professor of Astronomy in the University of Pennsylvania from 1779 till 1782, and was a trustee of the insti- tution, continuing in that office after its reorganization in 1791. He was made one of the secretaries of the American Philosophi- cal Society in 1771 ; became its vice-president in 1786 ; and suc- ceeded Benjamin Franklin as president, on his death in 1790. He was elected a Fellow of the American Academy of Arts and Sci- ences in 1782, and an Honorary Fellow of the Royal Society in 1795. He received degrees from the College of Philadelphia, William and Mary College, and Princeton College. He was tall and slender, quick in gait, had a countenance " indicative of intelligence, complacency, and goodness," and a disposition and manners that secured him friends and kept them. He bore testimony against the slave trade, and sympa- thized with the original motives of the French Revolution to such an extent that he assisted in the organization of the Dem- ocratic Society, and was made its president — but this was before the excesses of the Revolution were committed. While he 842 THE POPULAR SCIENCE MONTHLY. might be called self-educated, lie was not, as Mr. Barton shows, wholly without assistance in pursuing his studies, although some writers had mistakenly affirmed this, but that assistance was small. Dr. Rush assumed, in the eulogy he pronounced upon him, that the eminence he attained was to be ascribed " chiefly to his having escaped the pernicious influence of monkish learning upon his mind in early life"; otherwise, "instead of revolving through life in a planetary orbit," he might have spent his time "in composing syllogisms, or in measuring the feet of Greak and Latin poetry." He understood the German and Low Dutch lan- guages, acquired a reading knowledge of French, and " overcame in a great degree the difficulties of the Latin tongue." He was a firm believer in the Christian religion, though he was not at- tached to any church. That speculative disquisitions were of little interest to him is shown, perhaps, as much as by anything, by his remark concerning a conversation with a clerical gentle- man, that it was " not, perhaps, greatly to the satisfaction of either of us ; for he appears to be a mystical philosopher, and I, you know, care not a farthing for anything but sober certainty in philosophy." He published but little, because, as his biographer believes, he was too busy with work to give his time to the com- position of formal papers. The list of his contributions to the American Philosophical Society includes twenty-two titles of papers relating to his orrery ; the transits of Venus and Mercury ; the comet of 1770 ; a method of deducing the true time of the sun's passing the meridian ; the difference of longitude between the observations of ISTorriton and Philadelphia ; an explanation of an optical deception; experiments on magnetism; a remark- able meteor seen in 1779 ; a comet observed in 1784 ; a new method of placing the meridian mark ; an optical problem ; astronomical observations (on the Georgium Sidus and a transit of Mercury) ; an account of several houses struck with lightning ; another ac- count of the effects of a stroke of lightning ; several astronomical observations described in a single paper ; a mathematical prob- lem; a comet observed in 1793; the improvement of time-keep- ers ; the expansion of wood by heat ; a problem in logarithms ; and the mode of determining the true place of a planet in an elliptical orbit — his last paper, read February 5, 1796. To these is added his oration on " Astronomy," delivered before the Ameri- can Philosophical Society, on the 24th of February, 1775, and in- scribed " To the delegates of the thirteen United Colonies." In this oration, three years before the announcement of Mayer's discovery of the proper motion of certain stars, and six years before Her- schel's discovery of Uranus, the author put forth the suggestion, which has since proved a presage, that the fixed stars, and par- ticularly the milky way, would afford fruitful fields of observation. CORRESP ONDENCE. 843 CORRESPONDENCE. MOEAL INSTRUCTION IN OUR PUBLIC SCHOOLS. Editor Popular Science Monthly : IN "The Popular Science Monthly" for January I read with much interest, but not surprise, an article by Benjamin Reece, on " Public Schools as affecting Crime and Vice." The author very clearly shows that our school system is not elevating the moral standard of the rising generation, as had been so sanguincly expected, but rather, that as the minds of the masses are increased in knowledge, there is an equal if not more rapid increase of vice and crime. But the root of the evil is not in the system of pub- lic instruction, for, as a general rule, no teacher is given a school who does not bear an exceptionally good moral character, and a majority of them are members of good standing in the various churches. With this guarantee for the moral training of the pupils by precept and example on the part of the teachers, it seems to me that all is being done in that line that can be done. Furthermore, the Sunday school, where moral training is especially attended to, is now considered an indispensable adjunct to every church; yet, with all this, vice and crime are on the ascending scale, and in a most astonishing degree. It is a mistaken notion that simply to educate a people is to improve them moral- ly ; for a man can possess the most exalted moral qualities without the least intellectual culture, and vice versa. Now that our ethical hooes in public - school education are not fulfilled, what shall be further done to lessen this dark cloud of vice and crime ? My an- swer is, we must combine other lessons with our present system of moral teachings, and these other lessons must be ethical object- lessons. Man, to a very large degree, is an imitative creature, and especially so in child- hood. By constant imitation of what he sees others do, habits are formed, and, once formed at that early period, be they good or bad are rarely, if ever, entirely suppressed in after-years. All the ethical subject-les- sons may be given him that is possible ; but if there be object-lessons that go counter to them, these invariably take the deeper root, and soon nullify or supplant the former. With these truths before us, is it not the imperative duty of all— all who wish for good government, safety of person and prop- erty, and the advancement of the race— to become bright and living ethical object-les- sons to the rising generation ? Nor is this all that is to be done : we should discounte- nance and remove all who are not ethical object-lessons worthy of study. Man's imi- tative propensity is called forth principally by those whom he thinks are his superiors. Consequently all those in high places of all kinds who are pernicious object-lessons should be the first to be removed ; for, if the source be putrid, the onflowing stream becomes foul also. The author, in the arti- cle referred to, very truly tells us that the fall of the Roman Empire was " an effect of a moral ruin." Now, all readers of Roman historv know that the germ of this " moral ruin "" had its birth in the topmost strata of Roman society; and the masses, with ready imitativeness, became rotten to the core. The sad finale of that wonderful em- pire we all know. Is Roman history now preparing to repeat itself in these United States ? The indica- tions all strongly point that way. Do we not see venality and corruption pervading, more or less, every branch of the Government? Even our halls of justice are frequently tainted with it, while the politicians and office-seekers, with scarcely an exception, are prostituting the elective franchise throughout the land by a venal use of the "almighty dollar." This bribe -money is brought to bear almost exclusively upon the needy poor— making their pockets heavier, but dwarfing their moral manhood. With this state of things, is it to be wondered at that vice and crime are rolling up m billows mountain- high? Is it to be wondered at that our public schools, our Sunday schools, and pulpits are impotent to check the ap- proach of this "moral ruin"? Nor can it be checked until the wise and the good throughout the land determine to elevate to places of honor and trust only those who are calculated to make the best ethical ob- ject-lessons for the study of the rising gen- eration. How many can we point to who now sit in high places that would make good object-lessons for the study of all our school children? Purify the fountain, and the stream will become likewise limpid and pure. E- p- Meredith. Atlee's Station. Hanover County, Va., January 27, 1S90. POLITICS AND FARM MORTGAGES. Editor Popular Science Monthly : Sir : It was a gloomy picture of the condi- tion and prospects of agriculture in the United States which Mr. Joel Benton drew in his arti- cle entitled " The Decadence of Farming," in the November " Monthly." A similar view is presented by Judge Nott, in a series of articles published bv the New York " Evening Post ; " while recent reports of the State Commission- 844 THE POPULAR SCIENCE MONTHLY. er of Agriculture of Vermont and of New Hampshire substantiate these accounts as re- gards those two States. Abandoned farms in the East and farm-mortgage foreclosures in the West, Mr. Benton tells us, are becoming distressingly common, and many farmers who still hold and work their lands are struggling along under increasing indebtedness, or at best obtain only rapidly diminishing returns. Certain of our public men, however, deny that agriculture in the United States is suf- fering such a severe depression as these statements indicate. The Hon. Philetus Sawyer, Senator from Wisconsin, has said, according to the " Milwaukee Daily Journal," that he had never known of but one fore- closure of a farm mortgage in his section of the country, and the remark was used in de- bate in the Senate by his colleague, Hon. John C. Spooner. Our members of Con- gress might be expected to furnish reliable information. They are selected to make laws for the people, theoretically, because each one knows the condition and needs of his constituents, and how to provide for them. But the above assertion has been in- vestigated by the " Journal," with the result of proving, either that a false statement had been willfully made by one of the Senators, and repeated by the other, or that both were ignorant of affairs in the State they repre- sent that any observing man must be aware of. Foreclosures have to be advertised in the local papers, and, out of forty of the " Journal's " exchanges from within the State, foreclosure notices were found in fourteen. In these papers were thirty-two notices. The papers examined are not more than one eighth of those published in the State. The " Journal " also wrote for the records of foreclosures for the last ten years in most of the counties of eastern Wiscon- sin, as far north as the farming region ex- tends. In reply, letters were received, most- ly from county officials, which were published in the " Journal " of February 1st, and which showed that in nine counties of Wisconsin there have been seven hundred and eleven farm-mortgage foreclosures in ten years, in- volving $1,297,905.49. These counties con- tain about one sixth of the population of the State, and, allowing liberal margins, the " Journal " estimates that twenty-five hundred farm mortgages have been fore- closed in the whole State during the past ten years. Senator Sawyer resides at Osh- kosh, in Winnebago County, which is not one of the nine counties above mentioned, but foreclosures occur in the Senator's immedi- ate vicinity as well as in the rest of the State. The " Journal " quotes the " Oshkosh Times " as saying, " In the year 1888 ten mort- gages were foreclosed on farms in Winneba- go County, and in 1889 four more changed hands in the same way." And yet Politician Sawyer declared that he had never known of but one foreclosure in his section of the country. It is obviously unsafe to assume that what a politician don't know, therefore, does not exist. Senator Sawyer's alleged ignorance re- minds one of Sam Weller's behavior on the witness-stand in the great Pickwick trial, when his father had been guilty of disturb- ing the court. On that occasion the judge asked : " Do you know who that was, sir ? " " I rayther suspect it was my father, my lord," replied Sam. " Do you see him here now ? " said the judge. "No, I don't, my lord," replied Sam, staring right up into the lantern in the roof of the court. Senator Sawyer must have been looking hard in some other direction when notices of foreclosures in his section were floating about. Politicians do not deal much in facts. Their stock in trade is mainly exaggerated asser- tions, off-hand denials, and buncombe, and they trust to their eloquence, their artful ways of putting things, or to the authority of their official positions to secure belief. When it suits their purposes to have the truth known, they bring it out with a grand flourish of figures ; but when it seems to them more politic to keep the public in ignorance, they take refuge in general assertions. The true state of affairs in any given case can only be learned by searching out all the sep- arate facts. Just as truly as eternal vigi- lance is the price of liberty, the price of truth is thorough investigation. Very truly yours, Frederik A. Fernald. New Toek, February 22, 1S90. RIGIDITY OP THE SUSPENSION BRIDGE. Editor Popular Science Monthly : Sir: In the article on "The Evolution of the Modern Railway Bridge," by Prof. Jameson, he says (page 478) that "it" (namely, the cantilever bridge) " can be given great rigidity and stability, which are impos- sible in the suspension (bridge)," to which should have been added, " as usually built," because otherwise the statement would not be correct. Prof. Jameson himself correctly states in another place (on page 475) that "a sus- pension bridge is nothing else than an arch bridge turned upside down." It follows that a suspension bridge can be built just as rigid as an erect arch bridge. But it is demon- strable that a suspension bridge can be made more rigid, particularly against lateral forces, than an erect arch. A suspension arch is in stable equilibrium ; an erect arch is in un- stable equilibrium, and requires lateral brac- ing, which the suspended arch does not re- quire. Thus, if the steel arches of the St. Louis Railway Bridge were turned upside down, with the roadway suspended from them, and if the compression tubes were re- placed by steel links, the suspended arches EDITOR'S TABLE. 845 thus formed would have the same vertical rigidity as the existing compression arches, and it is obvious that the lateral bracing which is necessary for the tubes of the erect arch could be dispensed with for the links of the suspended arch. The question of anch- orages is outside of the comparison. The popular misconception as to sus- pension bridges is due to the many insuf- ficiently stiffened structures of this kind. No other bridge system can be built so im- perfectly stiffened, and yet be safe, as the suspension bridge. An erect arch bridge built in the same manner would fall of its own weight. Another popular and fashionable concep- tion, but a misconception all the same, is as to the merits of the cantilever bridge. Theo retically and practically, the cantilever of all bridge systems has the greatest deflections and oscillations under passing loads, all other things being equal, and therefore is the least rigid system. It has, however, its p;ood uses otherwise. Gustav Lindenthal. PiTTSBtrBG, Pa., February 2, 1890. THE SALT PRODUCT OF KANSAS. Editor Popular Science Monthly : Dear Sir: In your issue of January, 1890, page 430, under "Notes," it is said, " One hundred and fifty-five barrels of salt were manufactured in Kansas in 1888, and it is estimated that the output in 1889 will be not less than three times as large." From the annual report of the Secretary of the State Board of Agriculture for 1S88, it is learned that seven salt-works reporting produced 122,420 barrels. Of the seven, three reported to December 31st, and four to November 30th. One of the seven report- ing began March 1 5th, three in October, and two in November. From the same source for 18S9, 547,224 barrels of salt were manufactured and 19,- 056 tons of salt not put in barrels. Seven- teen companies reported in the latter year. I have bought a copy of " The Popular Science Monthly " since its first publication, and I was loath to pass such an error un- challenged. Success to you and yours. J. G. Wood. Topeka, Kansas, February 11, 1S90. [The number intended was 1 55,000 bar- rels. The dropping out of the thousands in transcribing the item escaped notice. On the basis of that number, the output of Kan- sas salt in 1889 would be, according to Mr. Hay's estimate, not less than 465,000 barrels. We thank our correspondent for giving us the opportunity of correcting the error. — Editor.] EDITOR'S TABLE. POLITICAL ECONOMY. AMONG the regularly constituted sciences that claim the attention of the world to-day, it can scarcely be said that political economy has an undis- puted place. Fourteen years ago, in an article on the centenary of the " Wealth of Nations " (which fell in the same year as the centenary of our Declaration of Independence), the late Prof. Jevons acknowledged that there was then far less agreement among teachers of politi- cal economy, in regard to the funda- mentals of their subject, than there had been fifty years earlier. He acknowl- edged, also, how little interest was taken in lectures on political economy at the universities, and how little weight was attached by practical men to proposi- tions or principles put forth as the re- sult of studies in that field. Row does the matter stand now that fourteen years more have flown? Has the credit of the economists of the generation that has passed away — the Mills, the Mc- Cullochs, the Seniors, the Says — been in any degree rehabilitated? Scarcely. As time goes on, it becomes increasingly clear that the whole work of these writ- ers was carried on too much in the re- gion of abstractions, and was too little vivified by direct contact with facts. Bacon long ago remarked on the error of those who supposed in nature a greater simplicity than really exists; and this error was abundantly exemplified by the classical or "orthodox" economists. It was to certain minds, no doubt, a fas- cinating pursuit to seize upon two or three general principles, and by their help to interpret and methodize all the complex phenomena of economic pro- duction, distribution, and exchange; but the process was hazardous in the 846 THE POPULAR SCIENCE MONTHLY. extreme, and much that passed for brill- iant philosophizing fifty or even thirty years ago is now regarded as little better than obsolete sophistry. Two of the latest works that have fallen into our hands — Mr. Wordsworth Donisthorpe's " Individualism ; a System of Politics," and Prof. Thorold Rogers's " Economic Interpretation of History " — illustrate this very strongly. "Practical men," says the former, "have long since ceased to attach any importance to the slipshod twaddle of those who pose as the the- orists of the art of wealth-producing." The latter, referring, as it would seem, particularly to Mill, says : " The politi- cal economist of the later school has thoroughly carried out in his own per- son the economical law which he sees to be at the bottom of all industrial progress — that of obtaining the largest possible result at the least possible cost of labor. He has, therefore, rarely been at the trouble of verifying his conclu- sions by the evidence of facts. He has, therefore, constantly exalted into the domain of natural law what is, after all, and at the best, a very dubious tend- ency, and may be a perfectly baseless hypothesis. His conclusions have been rejected by workmen and flouted by statesmen." We quote these passages not as fully indorsing them, but simply as showing to what extent the authority of a school that once was dominant is to-day called in question, if not discredited. At the same time, we fully believe that, before political economy can be a science in any satisfactory sense of the term, it has to be reconstructed and rewritten in the light of careful inductions from vast collections of facts. The basis of the "orthodox" economy was too nar- row, while its method was too deductive and dogmatic. Mr. Mill was a man of a mind at once acute and candid ; but he had not received the education that fitted him for the vast task which he assumed of reviewing the whole field of economics and enlarging its boundaries. In his youth he was overdrilled by a stern and remorselessly logical father. His attention was largely turned to classical, historical, and mathematical studies. In the region of natural sci- ence he never acquired any real com- petency. His tendency was, therefore, rather to read theories into facts than to make facts point the way to theories. His mind was extremely hospitable to new ideas, and his sympathies were quick and warm; upon the whole, few truer or better men have ever lived; but he had only a kind of literary ac- quaintance with economic facts, and it is not surprising that much of the rea- soning in which he indulged is now seen to have been concerned rather with fanciful abstractions than with real things. The political economy of the future will be of comparatively slow growth, but it will deal with men as creatures of flesh and blood ; not as automata moved by a few ticketed wires. The materials for the rising science are being laboriously gathered by many earnest investigators, who are fully alive to the errors of their predecessors, and who mean, therefore, to let the facts as much as possible speak for themselves. To the new political economy many inde- pendent lines of inquiry will contribute. The biologist, the moralist, the states- man, the lawyer, will all bring their stores of carefully assorted data; and, when these have been further arranged and correlated by minds of competent scope and grasp, we shall begin to see the outlines of a much more compre- hensive theory of economics than any that has heretofore been given to the world. In a word, science will under- take to organize a region that in the past has been too much given over to a pri- ori speculation, with its natural accom- paniment of presumptuous dogmatism. In future our concern will be not with the opinions of individual writers, but with their demonstrations; mere hy- potheses will carry no more weight in EDITOR'S TABLE. 847 this field than in any recognized depart- ment of natural science. What the effect upon social order and progress ot a really well-constituted science of po- litical economy will be it is not difficult to foresee. It will act as the great har- monizer of conflicting claims, and a most potent aid to the realization of justice in all human relations. And once more it will be proved that the only way to know things is to know them practically, and that the only way to build up a sci- ence is to bring the facts together, and all the facts. EXAMPLE IN MORAL TEACHING. Oue correspondent, who writes on " Moral Instruction in our Public Schools," in this number of the " Month- ly," points out an influence that pro- foundly affects the education of Ameri- can youth. What Mr. Meredith states in modern scientific language — that man is an imitative creature — had been learned generations ago from the expe- rience of practical men, and applied to education in the terse maxim, " Exam- ple is better than precept." Who that has had the care of children does not know how readily they do what they have seen older children and grown people do, and how hard it is to make them remember what they are told to do ! This should be a sufficient reason to make every person so order his daily life that it shall be an improving object- lesson to his own children and to the children who are to be the associates of his own. It should be a sufficient rea- son, also, as our correspondent points out, for elevating only men of high in- tegrity to positions of trust and power. In a country where it is possible for any native-born boy to become the head of the nation, youthful ambition has free scope. In order to satisfy this desire, the means by which public officials have risen to power are copied, the traits of successful men are imitated, even the manners and habits of those whom the people honor are adopted by the young. Hence it is extremely important that these means and traits and habits should be worthy of imitation. A determined effort should be made to check the de- moralizing influence at present exerted by American public life. If this is not done speedily, the evil will grow as slavery grew, till it finally challenges the nation to a life-and-death struggle whose outcome no one can foresee. The example set by the present genera- tion will determine whether the children now growing up shall be arrayed on the side of virtue and honor, or shall swell the ranks of corruption and crime. We emphatically dissent, however, from Mr. Meredith's proposition that all is being done in the public schools that can be done, in the line of moral in- struction. There is probably not a city or town in the country where morality is a recognized subject of instruction in the common schools, standing on the same footing as spelling or geography. Our schools give only information that will serve business purposes or disci- pline the mind, and utterly neglect training in right conduct. Their aim is to turn out money-getters, rather than to produce good citizens. If our schools were to give as much attention to judi- cious instruction in ethics as they now devote to the teaching of arithmetic, for instance, we believe that they would come much nearer to exerting the bene- ficial influence that is claimed for them than they do at present. AN UNFOUNDED STATEMENT. The " Chautauquan " is a magazine published for the benefit of what is known as the " Chautauqua Literary and Scientific Circle." It is religious in its general character. It contains " Sunday Readings " which are noted as " selected by Bishop Vincent." In one of these we lately read the following : " Some counselors, like Herbert Spencer, advise us to follow our own self-interest, with- out concern for others, with the assur- ance that. all will be thus happier, be- 848 THE POPULAR SCIENCE MONTHLY. cause more independent." Now, why a statement like this, which is absolutely without foundation and entirely mis- leading, should be considered as particu- larly suitable for Sunday reading, we, who are not of the " Circle," can not in the least divine. It is given to the members of the Circle, however, as the utterance of a leading educator, Dr. Ilill, President of the Baptist University of Rochester, and with the indorsement of Bishop Vincent, who, by selecting it, stamped it with his approval. The ordinary members of the Circle will, therefore, feel justified in accepting it without hesitation or reserve, and will form their opinion of Herbert Spencer accordingly. The wrong is done, not so much to Mr. Spencer, whose reputa- tion is established in the world of phi- losophy and science, as to the members of the Circle, who are made to receive a false impression of his moral teaching. If Bishop Vincent is not too busy with work of more importance, we would earnestly invite him to do one of two things — either justify the above state- ment in regard to Mr. Spencer or with- draw it, and that in the same columns in which the statement appeared. We affirm most emphatically that it does en- tire injustice to Mr. Spencer's teaching. LITERARY NOTICES. Physiology of Bodily Exercise. By Fer- nand Lagrange, M. D. The Interna- tional Scientific Series, Vol. LXVI. New Yorjc: D. Appletou & Co. Pp. 395. Price, $1.75. In early times men depended upon the constant use of their physical strength to obtain the means of subsistence, and to pro- tect themselves and their possessions against violence ; during a later period, when a class had arisen whose subsistence was provided by serfs, even these were still required by custom to use their muscles in warlike exer- cises ; at present a large and increasing por- tion of civilized men are engaged in occupa- tions which do not demand bodily exertion, and much of the labor formerly done by hu- man muscles is now performed by steam and electricity. The modern man has rev- eled for a time in bodily inactivity, but is now waking up to the fact that exercise is as essential to health and the enjoyment of life as sufficient food and sleep. But there are many who have not yet learned this les- son, and not all of those who are willing to take exercise have the right knowledge to secure for them its full benefits, or to pro- tect them against its misuse. Knowledge of this sort it is the object of the present volume to supply. We do not know of any other book that explains so fully as this what goes on within the body when the muscles are used. The author first de- scribes the process of muscular work, then explains the nature of fatigue, tells what changes in the body are produced by habitu- ation to work, what the essential characters of the different exercises are, what results are effected by different kinds of exercise, and closes by pointing out the office of the brain in exercise. The slightest movement performed by the human machine, he says, brings into play the neighboring parts, and sometimes also more distant ones. The old soldier who said, " When I had my two legs, I used to give a splendid blow with my fist," spoke sound science. Hence an exercise may produce marked effects in a part of the body where we should not have dreamed of looking for them. The great organic func- tions of the body are not isolated from the work of the muscles. More blood is drawn to the working muscular masses, and this stimulus to the circulation causes the lungs to draw in a larger supply of air. It is commonly said that work produces heat in the body, but in reality the heat is the cause of the work, and is itself produced by com- bustion of the nutritive substances derived from our food, of the fat, and, when these are exhausted, of the bodily tissues. The waste products of this combustion clog the muscles and are one of the causes of fatigue. Breathlessness is caused by violent exercise, which suddenly increases the quantity of carbon dioxide in the blood, and makes a great demand on the lungs to eliminate the poison. The stiffness of fatigued muscles is due to other waste products, notably the urates. Overwork causes more of such products to be produced than can be ex- creted ; hence they accumulate within the LITERARY NOTICES. 849 system, and their poisonous action often brings on a fever similar to typhoid. The organism is poisoned by its own products. Repose brings cessation of painful frictions of nerve-fibers and shocks of muscle-fibers, and allows time for the elimination of waste products and the repair of the tissues. The construction and action of the bodily organs become so modified by training that they can do more work without fatigue than before. Dr. Lagrange classifies exercises as those of strength, of speed, and of endurance. Be- fore passing to the general effects of exer- cise, he tells what groups of muscles are brought into action in the common exercises. Exercise produces salutary effects, he says, alike in those who assimilate too little and in those who do not dissimilate enough. The enlargement of the chest cavity is one of the most beneficial results of exercise, and many suppose that it can be best secured by the use of the arms, but Dr. Lagrange argues that exercises of the legs are most effective in expanding the lungs, because the legs can do more work than the arms, and thus create a greater respiratory need. The author then points out how some popular exercises cause deformity, and names others which do not have this tendency. It has been found that brain-work, like muscular exertion, is attended by a greater flow of blood to the working organ, an increase of heat, more vigorous combustion, and hence increased formation of waste materials. Mental overwork, also, leads to feverish states, which must be attributed to the ac- cumulation of products of combustion, as in the case of physical overwork. Now, while the muscles are the immediate agents in bodily movements, the exciting cause of the movements is the will. In executing a diffi- cult feat much brain-work is demanded in order to co-ordinate the muscles employed, and, if the brain is already overworked, the author concludes, such an additional mental task is injurious. Hence, for persons suffer- ing from mental overwork, exercises which can be performed automatically should be prescribed, rather than exercises of skill. The volume furnishes practical information which will enable the reader to so regulate the amount and kind of his exercise as to benefit and not injure himself. Its style is simple, and the reader is led along by such vol. xxxvi. — 54 easy steps that the course of the exposition can be readily followed. This latest addi- tion to the International Scientific Series ranks with the best of its companions in im- portance and general interest. The Continuous Creation. An Application of the Evolutionary Philosophy to the Christian Religion. By Muyron Adams. Boston and New York : Hough- ton, Mifflin & Co. Pp. 259. Price, $1.50. The author of this work, who is pastor of a Congregational church in Rochester, N. Y., believes that the " inevitable revolu- tion which Matthew Arnold declares is be- falling the religion in which we have been brought up, is part of that evolution by which God continues the higher processes of creation." He conceives the possibility of thinking under the principle of evolution and at the same time as a Christian believer, and believes that before long it will be found impossible to think clearly in any other way. The book is the outcome of a course of Sun- day evening lectures which he delivered to his congregation on evolution and its re- lation to religion. A key to the central thought of the work may be found in a com- parison, in the second chapter, between the former and more recent theories of creation. "According to the old story of creation, which was based upon no facts, but only upon a misinterpretation of revelation, God made man at one stroke, not as a sculptor makes a statue, not as an inventor makes a machine, but as the magician makes his prodigy. Accordingly, God is no constant and necessary factor of creation, but is a being who may be dispensed with, except for occasional irruptions into our region of space to perform wonders. Nowr, in place of such a conception, evolution offers a far nobler one ; and produces an array of facts, ever increasing in bulk and significance, to substantiate it. The process of change which goes on generation after generation, and age upon age, is creation. The Creator does not act as a magician, suddenly, as by mere impulse, but as the steady, eternal en- ergy, and ever according to that purpose which we begin to consider." Again, in the chapter on " The Idea of God " : " When we are told that evolution abolishes God, or renders him superfluous, we see, on the con- 850 THE POPULAR SCIENCE MONTHLY. trary, that evolution can not proceed one step without God. The materialist may de- clare that evolution proceeds by material energy or force. The agnostic may say that we do not know and can not know. The theist identifies the universal Power and In- telligence, proceeding by universal laws, as the Being of whom men have had imperfect intuitions, of whom men have had inspira- tions." As to the bearing of evolution on religion, we are told : " There is a feeling that evolution is dangerous. The exaggera- tion of that feeling is that evolutionary phi- losophy comes as a whirlwind to destroy re- ligion ; on the contrary, it comes to restore and revive it. My friends, evolution will prove itself dangerous to the kind of religion which treats it in that way. The religion that seeks to stand on the ground of opposi- tion to light, on the ground of resistance, will find itself more and more threatened and undermined by it." The evolution of the idea of immortality is also regarded as of the highest importance, as showing the consummation of the works of creation. Other special topics considered include the Bible as a record of religious gradual growth, " the problem of evil," the relations of evo- lution with Christianity and with special features and aspects of Christian faith, and its relations with social institutions and de- velopment. Finally, criticism, both higher and lower, and that of all shades and grades between, is declared really to have but the one purpose of coming at the abiding and the useful. The law of development being all-inclusive, " truth, sacred truth, must also have its course of development and progress. It can not long be contained in any state- ment or mass of statements. It increases by its own vitality and outgrows the most elaborate and finished form in which any age can put it. And, above all, religious truth is not stationary — a jewel cut and fashioned by skillful device ; it is in the na- ture of seed, inclosing the elements of growth, else it is no vital truth. . . . The serious concern of all men ought to be to know the truth, and to commit themselves to it. Not to commit themselves to the uncertainties, but to the certainties. So far as they do that, they will have no fear of the thrashing process of criticism which comes at various periods, and has now come." Epitome of the Synthetic Philosophy. By F. Howard Collins, with a Pref- ace by Herbert Spencer. New York : D. Appleton & Co. Pp. 571. Price, $2.50. We have here an eminently useful idea carried out in a very satisfactory manner. Mr. Collins has undertaken the by no means inconsiderable labor of going over the ten published volumes of Mr. Spencer's system of philosophy and summarizing them page by page. As he states in the " Compiler's Preface," " The object of this volume is to give in a condensed form the general prin- ciples of Mr. Herbert Spencer's philosophy as far as possible in his original words. In order to carry out this intention, each section (§) has been reduced, with but few exceptions, to one tenth ; the five thou- sand and more pages of the original being thus represented by a little over five hun- dred. The ' Epitome ' consequently repre- sents 'The Synthetic Philosophy' as it would be seen through a diminishing glass ; the original proportion holding between all its varied parts." Mr. Collins has aimed to present every salient point, to omit no essen- tial link in the argument by which the cele- brated exponent of the doctrine of Evolu- tion deduces the whole course of history and the laws that govern all nature, animate and inanimate, from certain fundamental postulates of the most abstract or at least of the most general kind. The first thing that strikes us is the severity of the test to which Mr. Spencer's philosophy has thus been subjected. Stripping off all externals and non-essentials, Mr. Collins has laid bare the very framework of the system. He has reduced the Synthetic Philosophy to a series of almost naked propositions, the connection or lack of connection of each of which with those that precede and follow can be seen at a glance. Opinions will doubtless differ as to the degree of logical coherence thus brought to light ; but we must declare, for our own part, that we are impressed anew, not only with the wonderful grasp of Mr. Spencer's mind, but with the philosophic unity of his thought. The apostle of Evo- lution has afforded us, in his successive vol- umes and in the successive chapters of each volume, one of the most magnificent exam- ples of evolution. The success with which he has developed his system speaks power- LITERARY NOTICES. 851 fully for its essential conformity with the true order of nature. It is hard to say whether Mr. Collins has rendered a greater service to those who are already familiar with Mr. Spencer's writings or to those who will first obtain some knowl- edge of them through his book. Certainly the former will thank him warmly for hav- ing placed within their reach a compend which will enable them at any moment to study to the greatest advantage the connec- tion of the different parts of Mr. Spencer's system, and to refer at once to any portion which requires for its full comprehension that more complete elucidation which Mr. Spen- cer's own works supply. In the preface he has written for the present work Mr. Spencer says that he was somewhat surprised to find that it had been possible " to put so much into so small a space without sacrifice of in- telligibility." We are not surprised at his surprise. The result must be attributed to Mr. Collins's skill ; but it also testifies to the essential lucidity of the text on which Mr. Collins was working. With the utmost skill he could not have made pages intelligible that were involved in obscurity and self-con- tradiction. No one who is really interested in Mr. Spencer's writings will care to be with- out the present manual. Giving, as it does, the gist of every paragraph in the original volumes, it will in many cases render the consultation of those volumes unnecessary. What Mr. Spencer thinks is here, we might almost say, fully set forth. His own books give us in addition confirmatory reasonings and illustrations. Any one, therefore, who, without knowing anything of Spencer, be- comes interested in Mr. Collins's epitome will probably seek the fountain-head whence so much of striking thought and compact argument has been derived. Naturally, certain parts of the present epitome are more effective than others. The section on the Unknowable in Mr. Spen- cer's "First Principles" does not admit of much condensation, and here the epitome is too abstract for anything like general read- ing, though possessing in common with all the rest a high degree of usefulness for seri- ous students of Spencer. The same remark applies to large portions of the " Psychol- ogy ;" but in the biological and sociological portions Mr. Collins has given us a version of Spencer that is at once pithy, vigorous, and thoroughly interesting. We could quote scores of paragraphs that tell their tale with admirable condensation and point, and that make good reading for any day in the year. The effect, therefore, of the present work, we may hope, will be to popularize to some ex- tent a system of thought which, abstract as it may seem, has been elaborated by its dis- tinguished author in the most practical spirit possible and which can not become more widely known without conferring propor- tionate benefit upon society. Special Physiology, including Nutrition, Innervation, and Reproduction. By John Gray M'Kendrick, M. D., LL. D., F. R. S., Professor of the Institutes of Medicine in the University of Glasgow, Fellow of the Royal College of Physi- cians of Edinburgh. London and New York: Macmillan &Co. 1889. 8vo. Pp. 803. Price, $6. Dr. M'Kendrick states in his preface that it has been his "endeavor throughout this volume to lay before the reader the main facts of physiological science, and as far as possible to state these facts in terms of meas- urement. The time has gone past for vague generalities in the description of physiologi- cal phenomena, and physiology is year by year drawing nearer to her true position as a science, dealing as strictly with the phenomena and basis of organic life as phys- ics deals with those of dead matter." The book is divided into sections, subdi- vided into chapters. The sections deal, in order, with nutrition ; food ; digestion ; ab- sorption ; the blood and its circulation ; res- piration ; assimilation or nutrition ; glyco- genosis ; excretion ; the income and expend- iture of the body ; animal heat ; the nervous system ; the senses ; the voice ; animal loco- motion ; and reproduction. There are four hundred and eighty-five illustrations. Dr. M'Kendrick's well-known scholar- ship is a guarantee that this book is a valu- able one. But that such is the fact would be quite apparent from inspection, even were his name not placed on the title-page. It gives the latest results of physiological study with accuracy and exactness. Wheth- er or not his expectations, quoted from the preface, are ever to be realized, he certainly has aided to advance the science of physiol- 852 THE POPULAR SCIENCE MONTHLY. ogy in the direction of his ideal. While the difficulties in the way of quantitative esti- mates of physiological phenomena are some- times very great, that is no reason for relax- ing efforts to overcome them, since in the accomplishment of this lies the hope of per- fecting the science. We have little space for special criticisms, but we think the author would have done better to leave some things to psychology, which he includes in his work. For in- stance (page G58), he speaks of pain as " a third kind of sensation, unlike touch and temperature." Now, there is a long-stand- ing controversy as to this point — whether pleasure and pain are distinct sensations or a quality of all sensations. Dr. M'Kendrick ought to have seen that this question could not be disposed of in a paragraph. Moreover, he should have recognized that it is clear- ly and peculiarly a psychological question. To include such a statement as he makes in a physiological work is certainly an error, whether he be right or wrong. And the as- sumption he makes is, besides, one which he would have great difficulty in substantiating. The likelihood is that pleasure and pain are not distinct forms of sensation, but qualities of all sensation whatsoever. Problems in American Society. By Joseph H. Crooker. Boston : George H. Ellis. Pp. 293. Price, $1.25. Six essays on moral and social problems of the time constitute this volume. The first is entitled " The Student in American Life," and its key-note is contained in the words "Americans are prone to ignore the vast practical importance of cultivated men." The second essay gives a sketch of the his- tory of scientific charity, from the " Ham- burg System " to the " Charity Organiza- tion " system of England and America, em- bodying many of the principles of this method of diminishing poverty. " The Boot of the Temperance Problem " is the subject of the next paper. The author does not think attacking the saloon-keeper is the way to reach the root of drunkenness. On the contrary, " true temperance methods," he says, " are such as reach the reason, the conscience, and the will of each individual." There is an essay on " The Political Con- science," which in many men is a coarser article than the private conscience. In re- gard to " Moral and Beligious Instruction in our Public Schools," the author maintains that, " logically there is no stopping short of a state religion, if religious instruction is insisted upon in the public schools " ; and in answer to the question, " Shall, then, our public schools teach a formal moral code?" he answers : " No ; rather let them possess a moral atmosphere, derived from the person- ality of the teacher." In the closing essay he discusses the fact that many villages hav- ing churches of half a dozen sects are almost destitute of real religion. The Town-Dweller : His Needs and his Wants. By J. Milner Fothergill, M. D. With an Introduction by B. W. Bichard- son, M. D., F. B. S. New York : D. Ap- pleton & Co. Pp. 118. Price, $1. Two general reasons are given by Dr. Fothergill for the dwellers in towns being inferior physically to the inhabitants of the country. First, a natural selection draws the slight men of active brain from the country into the towns ; and, second, the con- ditions of life in the towns are hostile to physical vigor. In successive chapters of this book the dangers in these conditions of city life are pointed out. The house of the town-dweller may be built on a rubbish-heap, and have smoky chimneys and dangerous plumbing. His surroundings may include noisy or ill-smelling premises, while street noises afflict the best city neighborhoods. The air he breathes lacks ozone, and is charged with the oxides of carbon, sulphur dioxide, and metallic fumes, and contains often irritating dust. The water-supply of towns is not always wholesome. The town- dweller eats too much meat and white bread, and he rejects fat, which shows that his di- gestive organs are too weak to digest it. Too much tea and alcoholic beverages are con- sumed by town - dwellers, and the liquors often contain substances more harmful than alcohol. Most of the work of the town is done indoors, and in a hot atmosphere, which favors the handling of small objects. Town amusements are also mostly carried on indoors, and furnish little of the recreation needed. The brain and nerves of the town- dweller are unnaturally developed, while his muscles and internal organs are proportion- ately weakened. Blight's disease and dia- LITERARY NOTICES. 853 betes are especially associated with the men- tal activity of town-dwellers. Their children are sickly, and if it were not for the constant inflow of new blood from the country, the towns would be depopulated in three or four generations. Dr. Richardson, in his intro- duction to the volume, says, " The divisions are excellent, the title of each division at- tractive, and the mode of progress from stage to stage artistic." He draws attention to certain " short, sharp sayings, each one in its proper place, and easily learned and not easily forgotten." As samples of these he quotes, " Flags and pavements produce no grass." " Brains are the finest raw material of a country." " To kill the weak and in- jure the middling is a long price for educa- tion." He calls it also an eminently sug- gestive book, which, if the author had lived, would doubtless have been expanded. On the Creation and Physical Structure of the Earth. By John T. Hakrison. London and New York : Longmans, Green & Co. Pp. 189. Price, $2.50. The author offers this production as an essay toward a theory of the formation of the earth's crust. In his discussion he makes liberal use of passages in the writ- ings of the leading geologists, which often reveal wide differences of opinion concern- ing the questions discussed. He also puts at the heads of several chapters, and scatters through his text, passages from the Bible, with which he evidently deems it essential that his views should conform. A striking case of this tendency to subordinate his opin- ions to the imagined geological teachings of the Bible is where he says that the earth- quakes which now occur result from disturb- ance of the crust in one or other of the old lines of rupture, and asks, " Who can ear- nestly consider this condition of the earth and say that it may not be nearly ripe for another paroxysm ? " He then quotes from Prof. Hitchcock to the effect that the earth contains within itself chemical energies suffi- cient to accomplish its own destruction, and adds, " We have the yet older and surer reve- lation that the earth shall reel to and fro like a drunken man, and, when enveloped in flames, all the works of man shall be burned up." This, in spite of the fact that the pro- gressive cooling of the earth points to its end in frigidity. A Test-Book of Animal Physiology, with Introductory Chapters on General Bi- ology and a Full Treatment of Repro- duction. For Students of Human and Comparative (Veterinary) Medicine and of General Biology. By Wesley Mills, Professor of Physiology in McGill Uni- versity and the Veterinary College, Mont- real. New York : D. Appleton & Co. 1889. 8vo. Pp. TOO. The plan of this important work is new. It adopts the comparative method, begins with general biology, treats of the cell as the unit, gives an account of unicellular vegetal organisms both on the morphological and the physiological side, then of unicellular animals, next of multicellular organisms, leading up to a consideration of the ani- mal body, the animal kingdom and man's place therein. Following all this is a full exposition of the origin of life in general and of reproduction, very admirably pre- sented. Then the chemical constitution of the animal body is taken up, the blood and the contractile tissues are examined, the graphic method is extensively applied to the study of muscle physiology, the circulatory system is explained, succeeded by an account of the digestive system. Excretion is next dealt with, then the metabolic or chemically transforming processes, while the nervous system and the senses form the concluding portions of the work. The plan has obvious advantages. It is much better adapted to giving the learner a correct and comprehensive view of physi- ology than treatises in the usual form and order. Moreover, the work in question is admirably executed and has all the charac- teristics of a truly scientific production. It is certain that physiology must be hereafter studied with reference to general biological laws, and not by piecemeal methods. Then books like the present one will inevitably su- persede the older text-books, presenting a less unified physiology. Dr. Mills's volume will help this progress. It may be safely recommended as one of the best treatises on the subject extant, and in respect to method we know of none more praiseworthy. La Pisciculture en Eaux Douces (Fish Culture in Fresh Waters). By A. Gobin. Paris : J. B. Bailliere et Fils. Pp. 360. M. Gobin has given us a handy and use- ful book, comprehensive and practical. The 854 THE POPULAR SCIENCE MONTHLY subject has been introduced into the agri- cultural and national schools of France, and the art has become there, according to the author, not only a regular branch of indus- try, but also the fashion. It is recommended as being equally well adapted to women with the care of poultry, bees, and silk-worms. "As a recreation, it interests the mind and the eyes ; and it has been well tested as an economical resource. As a regular pursuit, it has been taken up and then dropped several times ; in the present effort that is making to establish it on a systematic basis, the United States is acknowledged to be in ad- vance of any of the European countries which are named. Of its importance, the author well says that, in a period of civiliza- tion like that which we have reached, every waterfall, however slight it may be, should and can be utilized as a motor force, and every stream and water surface should be made to support the maximum of aquatic in- habitants best suited to purposes of food. To obtain this condition, nothing has to be created. All that is necessary is " to study and adopt what has been done in England, Switzerland, some places in Germany, and especially in the United States." In the several chapters and sections of the book are considered the properties of fresh water, the different kinds of fish, natural and arti- ficial breeding and feeding, the construction and management of fish-ponds, the manage- ment of lakes and methods of dealing with running waters, migratory and " sedentary " fish, crustaceans, lagoon fish, and sea fish. The whole is abundantly and satisfactorily illustrated, and a classified list of the fresh- water fishes of France is added. A paper that will have value for manu- facturers of iron and steel is that on The Construction of Cupolas for the Melting of Pig-Iron, by M. A. Gouvy, Jr., translated by W. F. Durfee, which appeared in the " Journal of the Franklin Institute " for January, 1889. It presents, in one compre- hensive view, most of the experiments that have been tried in many lands, with a hope of improving the working of cupolas ; and the translator believes that, if its conclu- sions are intelligently followed by users of cupolas, very large economies of fuel will result. Among the experiments whose his- tory is given in this sketch are the employ- ment of hot blast, utilization of the gas es- caping from the top of the furnace, changes in the form of the vertical section of cupolas, cooling the walls, equal distribution of the blast, suction-blast, gas-firing, and complete combustion of the carbonic oxide. The au- thor points out clearly the advantages and disadvantages of each of these devices, aud at the end sums up his conclusions. A table giving the relative dimensions, the product, and the consumption of fuel in thirty-three cupolas of various construction accompanies the paper. The purpose of the manual on Foods for the Fat, by Nathaniel F. Davies (Lippincott, 75 cents), is to enable persons suffering from corpulency to so regulate their diet as to cure their ailment. The first division of the vol- ume tells the amount of food required by persons in ordinary occupations, the uses of fat in the body, and the effect on corpulency of exercise, stimulants, tea, coffee, and other beverages. In the second part of the book a list of articles which may be eaten by the corpulent is given for each month, and some- thing more than half the volume is devoted to recipes for preparing such articles. Dr. Ceorge 31. Gould, of Philadelphia, publishes a report of three cases in which, respectively, chorea, flatulent dyspepsia, and palpitation of the heart had been caused by eye-strain, and were cured when the eye was relieved. Following the line of research thus opened, the author examines the rela- tion of sexualism and reflex ocular neuroses, and finds a means of accounting for the head- aches of women in the years between puberty and middle age, and for various other func- tional derangements. The object of the Inventor's Manual (J. F. Davidson & Co., New York, f 1) is " to give the inventor and patentee some hints on patents generally, together with information on ways of exhibiting inventions, bringing them to public notice, and effecting sales." Among the subjects treated in this work are, how to invent, how to secure a good patent, value of a good invention, how to exhibit an invention, how to interest capital, how to estimate the value of a patent, advice on selling patents, advice on the formation of stock companies, forms for assignments, licenses, and contracts, State laws concerning LITERARY NOTICES. 8S5 patent-rights, and other items of information not generally accessible to the inventor or manufacturer. The following five books and pamphlets are issued by the Woman's Temperance Pub- lication Association : The Year's Bright Chain (price, 50 cents) consists of twelve pages of quotations from the writings of Frances E. Willard, alternating with full- page pictures representing the months. Each picture is accompanied by a couple of stanzas of verse telling the wish the month grants to a boy and to a girl. A finely en- graved steel portrait of Miss Willard forms the frontispiece. The artistic and mechani- cal quality of the book can not fail to delight her young admirers. Frances Raymond's Investment, by Mrs. S. M. I. Henry (price, 50 cents), is the story of a woman's complaint against the State for the loss, due to the licensed saloon, of what her boy had cost her. The Unanswered Prayer ; or, Why do so many Children of the Church go to Ruin ? also by Mrs. Henry (price, 50 cents) consists of several chapters of counsel to mothers in regard to saving their children from the evils and dangers that beset them. Songs of the Young Woman's Christian Temperance Union, by Anna A. Gordon (price, 25 cents), consists of ninety-five pages of words and music, suitable for temperance meetings. Crusader Programs (price, 25 cents) is a collection of exercises, consisting of recita- tions, dialogues, etc., interspersed with songs, and designed for the Loyal Temperance Legion, Sunday schools, etc., and adapted to Arbor-day, Easter, Decoration-day, and other occasions. A new review, called The Arena, has been started in Boston, under the editorship of B. 0. Flower (The Arena Publishing Company, $5 a year). The promise that it will be il a field of combat " where the many social, ethical, and political questions of the day will be fought over, seems likely to be veri- fied, for among the contributors to the first two numbers are some of the most belligerent writers for the press who are now in the field. These are such as Robert G. Ingersoll, who opens the first number with an article on " God in the Constitution " ; Lawrence Gronlund, who writes on li Nationalism " ; Hugh 0. Pentecost, on " The Crime of Capi- tal Punishment"; Henry George, on the " Rum Power " ; Rev. Minot J. Savage, W. H. H. Murray, Mrs. Mary A. Livermore, and Hudson Tuttle. Besides these serious dis- cussions, The Arena offers papers on literary subjects, by Dion Boucicault, Louis Frechette, and others, and poetry and fiction by Joaquin Miller, W. H. H. Murray, Edgar Fawcett, and others. Each number is to have a portrait as a frontispiece ; that of Dion Boucicault appears in the first number, and that of Rev. Minot J. Savage in the second. In Some Social and Economic Paradoxes — a reprint from the " American Anthro- pologist"— Mr. Lester F. Ward sustains a number of theses, the contrary of which i9 now more currently held, such as that " The artificial is superior to the natural ; " " Social activities may be artificially regulated to the advantage of society " ; " Reforms are chiefly advocated by those who have no personal interest in them " ; " Discontent increase with the improvement of the social condi- tion " ; " The means of subsistence increases more rapidly than population," and others on the relations of capital, profits, and wages. A pamphlet published by E. Truelove, of London — Home Rule and Federation is its name, and A Doctor of Medicine its author — advocates the federation of nations on a plan resembling that of the United States as the cure or most effective palliative for existing social and political evils. It might begin with states already showing inclina- tions in that direction, like those of the Balkan Peninsula and Scandinavia; then bring in France and England, whereby, it is suggested, a solution of the Irish question may be found; and at last be made uni- versal. Some years ago Mr. /. C. Pilling under- took the compilation of a bibliography of North American languages ; visited many public and private libraries, and corre- sponded extensively ; and embodied the re- sults of his researches in a volume of which a limited number of copies were printed and distributed. He has since continued his in- vestigations, and has collected enough new material to lead to the belief that a fairly complete catalogue of the works relating to each of the more important linguistic stocks of North America may be prepared. Four 856 THE POPULAR SCIENCE MONTHLY. catalogues of the new series have been pub- lished by the Bureau of Ethnology. The first of them is the Bibliography of the Eskimo language, which is spoken by a people covering a very extensive range of territory and widely scattered, and is repre- sented in many dialects. The earliest date recorded in the bibliography is 1*729, and it is brought down to include titles that came in while the work was in process of type- setting. Next in order is the Bibliography of the Siouan Languages, in preparing which the compiler enjoyed the advantage of the fact that many of those who have fash- ioned the literature of the language are still living, and he has had personal intercourse or correspondence with a number of them for several years. The publications of the Siouan group cover, perhaps, a wider range than those of any other linguistic group of North America. Nearly every dialect is rep- resented in print or manuscript, either by dictionaries or extensive vocabularies, and pretentious grammars have been prepared of at least five of the languages. The third bibliography is of the Iroquoian Languages to which group, perhaps, belongs the honor of being the first of American languages to be placed upon record. The languages most largely represented are the Mohawk and Cherokee. Of manuscripts, mention is made of a greater number in Mohawk than in any of the other languages. Grammars have been printed of the Cherokee, Huron, and Mohawk ; dictionaries in Huron, Mohawk, and Onondaga, and, in manuscript, of Seneca and Tuscarora. The Muskhogean Languages, to which the fourth bibliographical paper is devoted, are represented by 521 entries, of which 467 relate to printed books and arti- cles and 54 to manuscripts. Les Trois Moitsquelaires — The Three Musketeers — of Alexandre Dumas is pub- lished by Ginn & Co., in an edition prepared for the use of schools, by Prof. F. C. Suni- chrast, of Harvard College. This is one of the best works of the lively novelist, and belongs to a series to which Mr. George Saintsbury has ascribed remarkable and almost unique merits. But all of Dumas's works are liable to objection because of their containing passages unfit to be put into the hands of pupils. The present edition is an attempt to offer a condensation of the book, in which, while leaving the main feat- ures of the story and the brilliant and de- lightful passages untouched, all that is ob- jectionable is excluded, and the volume is brought within such limits of length that it may be conveniently used as a text-book. The notes include explanations of difficult passages and allusions, and notices of his- torical persons and places mentioned in the story. Price, 80 cents. The Young Folks' Library, edited by Larhn Bunion, LL. D. (Silver, Burdett & Co.), is a series of supplementary readers, designed to give, besides practice in reading, useful information in special fines of school study, and selections from the best litera- ture. The World and its People is a section of this library devoted to geography. Book I, First Lessons, starts with the building of a doll's house with blocks, and proceeds to the drawing of a plan of a school-room and play-ground, a village, and a city, after which the meaning and use of a map and of the points of the compass are fully explained. Spelling lists follow each lesson, and the volume is illustrated. Book II, Glimpses of the World, aims to present such ideas of per- sons and places as will interest children and fit them for the study of geography proper. The maps inserted usually represent portions of the United States, and at the same time illustrate general geographical features of the world. The frontispiece is liable to give children a wrong idea of the size of the earth ; it represents the globe floating in space, with a swallow the size of Greenland flying over it about a thousand miles above the atmosphere. Many poetical pieces are introduced into each book. Other volumes are to follow. Prof. Alexander M, Bell has embodied his widely known system of sound notation in a Popular Manual of Vocal Physiology and Visible Speech (E. S. Werner, New York, 50 cents), designed as a text-book for teach- ing these subjects in schools and colleges. It gives a complete view of the actions of the vocal organs and the resulting elements of speech. The symbols used to represent the various motions and positions of the organs constitute visible speech. The mas- tery of spoken languages, the exact acquire- ment of native or foreign pronunciations, the correction of defects of utterance, and LITERARY NOTICES. 857 the teaching of articulation to the deaf, are uses to which Prof, Bell's system is applicable. References to the United States Constitu- tion, by William E. Foster, is published as No. XXIX in the series issued by the Society for Political Education, 330 Pearl Street, New York. Mr. Foster, Librarian of the Providence Public Library, is one of the scholarly men who seek to make the collec- tions of books committed to their care of the largest possible public benefit. This pamphlet is an object-lesson in reading with a purpose. It gives clear references by chapter and page to everything in print having a bearing on the Constitution of the United States. We are given a list of the works showing the antecedent influences in antiquity, in German and English institu- tions, and in American colonial history. The more immediate causes are traced in the records of the Annapolis Convention, 1786, and the Philadelphia Convention, 178*7. Next Mr. Foster analyzes the Constitution as framed and adopted, and shows the various sources of its articles. He then proceeds with Constitutional History since 1789, giv- ing reference to all the leading expositions and commentaries on the Federal and State Governments, with notes on the various amendments, and on the comparisons of other governments with that of the United States. An appendix summarizes the decis- ions of the Supreme Court since 1865 on questions affecting national or State suprem- acy. Mr. Foster has performed his task with conscientious care and thoroughness. His References will save every student of the Constitution much unnecessary labor and bring before him much that he might never otherwise know. (Price, 25 cents.) Prof. Simon iV. Patten, of the University of Pennsylvania, in his pamphlet on The Rational Principles of Taxation, makes a debatable contribution to a difficult theme. He maintains that the wastes and burdens of competition in methods of distribution are increasing ; the great cost of solicitation and advertisement in their manifold forms he holds to be the chief reason why science applied to industry has not enriched the na- tion as it should. His remedy for undue and wasteful competition is of a heroic kind ; it is no other than an adaptation of the high- license plan in dealing with the retail liquor trade. Prof. Patten holds that while that plan deprives no patron of his desired bev- erages, effects no increase of prices, it re- sults in notable economy to the community in extinguishing one half or more of the saloons, with their outlays for rent, attend- ants, and so on. He argues that a similar reduction of the ranks of all distributive classes by a high special tax would inure to a general promotion of prosperity in which these classes would perforce share.

The Disaster at Toronto. — On the even- ing of February 14th the larger portion of the University of Toronto was laid in ashes. Its governing body have met the disaster with commendable promptitude and spirit. Plans are afoot not only to rebuild the structure in its original beauty of outline, but to extend it for the accommodation of the ever-growing number of the university's students. Last summer the university was the home of the American Association. The cordial hospitality of its venerable principal, Sir Daniel Wilson, and his staff of profess- ors, on that occasion, have done not a little to widen the circle of sympathy felt with Ontario's capital in its grievous loss. Irish Holiday Customs. — A paper by Mr. James Mooney, on the " Holiday Customs of Ireland," presents the Celtic peasant in a different aspect from that under which he is exhibited in the English Unionist accounts of his misery and turbulence, and one which, we may easily believe with the author, is more really illustrative of his character and home life. The old customs are, however, decaying in Ireland as elsewhere, and many of the observances which were once general are now confined to remote mountain dis- tricts or live only in the memory of the older people. Yet others are still common through- out the country. As there is but little com- munication among the peasantry of differ- ent districts, except at the fairs in the sum- mer-time, the customs common in one par- ish are sometimes entirely unknown in an- POPULAR MISCELLANY. 859 other hardly ten miles distant. While a number of the holiday observances are more or less common to all the Aryan natives, the features more peculiarly Irish are mainly derived from the old Druidic worship. Aside from some essentially foreign customs not noticed in Mr. Mooney's paper, many of the genuine Irish observances have been consid- erably modified by English influences. This is especially true of the May-day and Christ- mas celebrations ; and many holiday rhymes and children's rhymes, riddles, and other formulas — even in the remote parts, where Celtic is the ordinary language of the peo- ple— have been imported bodily from Eng- land. Mr. Mooney has also reprinted, from the " Journal of American Folk-Lore, " a paper on the " Folk-Lore of the Carolina Mountains," which, while it can hardly be summarized, is full of matters of curious and quaint interest. Ants and the Plants that harbor them. — In a paper read before the British Associa- tion on the Humboldtia laurifolia as an ant- harboring plant, Prof. Bower observed that the peculiar relations between plants and ants had been the subject of considerable observation from time immemorial. The literature on the subject could be traced as far back as 1750, and Captain Cook, in de- scribing his voyages, distinctly alluded to the matter. In one place he said that he had seen on a certain tree a number of black ants which perforated the twigs, and, after eating out the pith, formed a lodging in the cavity, and yet the tree continued in a flour- ishing condition. In tropical climates there were many plants pre-eminently associated with ants. The Italian botanist Picari con- tended that the relationship was advanta- geous alike to the plants and to the ants. The former afforded shelter to the latter, and in some cases supplied them with food. In the course of a short discussion Dr. Tieman said there were five species of Humboldtia in trop- ical countries. The ants took advantage of the hollowness of the plants, but he did not think the latter derived any benefit from their presence. Alcoholism and Consnmption. — In three professional papers Prof. Thomas J. Mays exhibits relations between consumption and nervous disorder, and between consumption and alcoholism. The former connection is illustrated by the citation of numerous cases in medical practice, the deductions from which lead to the conclusion that " he who looks at the disease which goes under the name of pulmonary consumption solely from a pulmonary standpoint obtains but a very limited and distorted conception of its magni- tude and nature ; but that he who takes the view here indicated will realize that the lung affection is only a special manifestation of the disease which invades the whole body ; and that all its diversified symptoms, such as fatigue and exhaustion, anorexia, dyspep- sia, wasting, dyspnoea, sweating, diarrhoea, haemoptysis, intercostal tenderness, hoarse- ness, aphonia, oedema, are not the conse- quences of the pulmonary disease, as is gen- erally believed, but in all probability find a common bond of union in a general disorder of the peripheral nervous system." In the other aspect of the theory cases are cited to prove that " alcoholism and phthisis are not mere coincidences, but that they have a rela- tionship so intimate that one may be con- verted into the other " ; and that pulmo- nary phthisis can be produced through the toxic action of alcohol on the nervous system. " Such, then, being the relation between al- coholism and pulmonary phthisis, it is very readily understood why these two diseases should so frequently change places in differ- ent members or generations of the same family, and why they are so often associated with various other nervous disorders." Old Panama Canal Projects. — The feasi- bility of cutting a canal across the Isthmus was discussed by William Paterson, in 1701, in connection with his Darien scheme, but only incidentally. He thought that the ca- nal could be easily cut for six out of the eight leagues between the oceans, while the other two passages would be difficult. Hum- boldt, in a report made in 1799, enumerated nine different points at which the two oceans might be connected. Previous to this, in 1788, a passage between the two oceans for small craft was actually accomplished. The author of this achievement, says Mr. J. Stephen Jeans, in a paper on the subject, was the curate of Nevita, who induced his Indian flock to cut a trench between the upper streams of the San Juan River, near 86o THE POPULAR SCIENCE MONTHLY. Chirambira Bay, and the higher waters of the river Atrato, which flow into the Atlan- tic through Choco Bay, in the Gulf of Da- rien, so that they could pass from the Carib- bean to the Pacific in their canoes. In carrying this passage into effect, the Aras- tradera, or summit level, a plain about three miles in width, formed by an interruption of the mountainous ridge, was cut across. The passage was, however, dangerous and diffi- cult at all times, even for canoes, and the communication has now for many years been neglected and disused. Land Tenures in China. — While the em- peror theoretically owns all the land in Chi- na, the private owner has as absolute a property in it as he can have under any gov- ernment. The tenures are military and com- mon, the latter applying to far the largest proportion of the territory. , It exists upon the conditions of payment of the land-tax, the supply on demand of statute labor to the authorities, and the payment of a fine on alienation. The land-tax is assessed in a fixed sum on the district magistrate, who recovers from the tenant, but is sometimes remitted in case of a great calamity. The supplying of statute labor has almost fallen into disuse. The fees are payable on the transfer of land by sale or mortgage, suc- cession or inheritance. About half the soil is probably the property of the tenants who till it ; but large tracts are also owned by " literati and gentry," who lease it to small farmers for a rental consisting of a propor- tion of the crops fixed according to the qual- ity of the soil. The rents are paid as soon as the crop is harvested, and, being seldom in arrear, evictions are rare. The laws are all in favor of the tenant, who pays no taxes or rates, and takes everything, including his house. There is every possible variety of arrangement in the ownership of land. There are absolute sales and sales in which the vendor reserves the right to a share in a future rise in value ; revocable and irrevoca- ble sales ; and dual ownership, in which one man owns the surface and the other the soil, and is liable for the taxes. Refrigeration by Ammonia. — Ammonia has been very generally employed for re- frigerating purposes in the United States and Germany, and to some extent elsewhere, for ten years or more. Other agents used for this purpose are methylic ether, Pictet's liquid, sulphur dioxide, and ether. Ammonia in its anhydrous condition possesses in an eminent degree the properties most desired in a refrigerant, for it boils at the low tem- perature of 374-° Fahr., while its latent heat of vaporization is 900°. Two distinct sys- tems are employed in the use of ammonia, differing from one another in the method of securing the rejection of heat during conden- sation of the vapor, while the mere evapo- rating or refrigerating part of the process is the same in both. In the absorption process ammonia and water are vaporized together and then fractionally condensed by cooling. The water, condensing first, is caught and run back to the generator, while the nearly anhydrous ammonia is collected separately. With this process 200,000 units of heat per hour may be eliminated by the consumption of about one hundred pounds of coal, with a temperature in the refrigerator of about 20° F. In the compression process the ammonia vapor is drawn from the refriger- ator and compressed by a pump and deliv- ered into the condenser and liquefied at the temperature of the cooling water. It is more economical than the absorption pro- cess, and is adequate to the elimination of 240,000 units per hour. The process is ap- plied to ice-making and to the cooling of stores and rooms. The Tahl-tan Indians of British Colum- bia.— An account of this people by Mr. J. C. Callbreath, included in a report of an explo- ration by George M. Dawson, gives their max- imum height as about five feet seven and a half inches, and maximum girth of chest about thirty-seven inches. Their heads are small, and the feet and hands are generally small, as are also the wrist and ankle, espe- cially in the women. Traders sell more No. 2 women's and No. 6 men's shoes than any other sizes. No men's hats above No. 1 are sold. Bialf-breeds from a white man and a Tahl-tan woman are more like the father than the mother, and three generations where the father is in every case white seem to oblit- erate all trace of Indian blood. The children are more cunning and clever when young than those of the white race, but grow dull as they age. Yarn is spun from the wool of POPULAR MISCELLANY. 861 the mountain goat and is woven into excel- lent blankets, which are highly colored and ornamented. The process of boiling water with hot stones in baskets or wooden bowls was formerly common. The dances of the Tahl-tan are tame affairs compared with those of the coast tribes, but their musical capabilities are considerable. Kinship, so far as marriage or inheritance of property goes, is with the mother exclusively, and the father is not considered a relative by blood. Mr. Callbreath tells of an instance where a rich Indian would not go out or even con- tribute to send others out to search for his aged and blind father who was lost and starving in the mountains. Not counting his father as a relative, he said, " Let bis people go and search for him." Yet this man was a more than average good Indian. A man's female children are as much his property as his gun, aud he sells them to whom he pleases. If the husband pays for his wife in full and she dies, even ten years after- ward, the father is bound to supply a wife, if he have any more eligible daughters, with- out additional payment. Their laws are based on the principle that any crime may be condoned by a money payment. Their religious belief was simply what their medi- cine-men might lay down for them from time to time, and the idea of a Supreme Being was very obscure if not altogether wanting. They have no fear of death except from dread of the pain of dying. There is a be- lief propagated by their medicine-men that the otter gets inside their women and some- times causes death by a lingering illness, in other cases allowing the woman to live on till she dies from some other cause. An African Tribe of Promise. — The Benge are a very intelligent and pleasant tribe which Lieutenant R. Kund's exploring party found occupying an " immense clear- ing " in the midst of the Congo wilderness. Their village, surrounded by large manioc- fields, consisted of a street about fifty yards wide extending farther than the eye could reach. The huts of the villagers squarely faced the street on either side, and behind them were well-kept plantations of bananas, backed by oil palms, with the giant trees of the forest looming in the rear of all. The race is of a very fine type, with a brownish- red complexion some degrees removed from black, fine, manly features with an intel- lectual cast, and cleanly and orderly in habits. They are good hunters, and practice wood- carving and other arts with a skill that would do credit to Europeans. They have attained in all respects a higher standard of civilization than is to be found among the other tribes of West Africa. They exhib- ited none of the stupid superstition in the presence of the travelers which had ap- peared in other places, and showed no signs of cannibalism or fetichism or coarse idolatry. Effect of a Cobra's Bite.— The taxider- mist of the Victoria Museum was bitten in the hand by a cobra, from which the poison- bag had been extracted, while feeding it. Supposing the bite to be harmless, he took no notice of it till pain and nausea began. Then all the usual antidotes were tried with- out effect. The man lost the power of speech, became paralyzed in his muscular system, and ceased to breathe. Artificial respiration was applied for eight hours, after which he began to breathe again and gradu- ally regained consciousness. After two days he was able to tell his friends that he had been fully aware of all that was go- ing on during the efforts to restore him, but had not been able to move a muscle or to make his feelings known. He could see and hear and feel, but not move or twitch. He was afterward attacked by high fever and inflammation of the lungs, from which he died on the Sunday following the Wednes- day on which he was bitten. Dnst essential to Fogs. — Nearly ten years ago John Aitken, of Edinburgh, proved ex- perimentally that the presence of dust was essential to the formation of fog and cloud. He connected two receivers, one containing common air, the other air freed from dust by passing through cotton - wool, with a boiler. When steam was admitted into the first receiver, a fog formed within it ; but when allowed to enter the one containing filtered air, not the slightest cloudiness was produced. Particles of water-vapor do not combine with each other to form a cloud- particle, but must have a free surface on which to condense. The particles of dust serve as nuclei on which the vapor condenses, 862 THE POPULAR SCIENCE MONTHLY. and hence the more abundant the dust the more dense the cloud. When the vapor in the second receiver was brought by circula- tion against the sides of the receiver, it gradually condensed on these surfaces. The density of the fog formed in common air shows what a large amount of dust is pres- ent every day in the air around us. But the particles of fog do not represent all the dust- particles in the air. If enough steam is blown into a receiver full of common air to produce a dense fog, and after the fog has settled more steam is blown in, another fog will form on the dust which still floats in the air. If this is repeated a number of times, a less dense and coarser-grained fog forms each time, till at last no fog is seen, but the condensed vapor falls as rain. These dust-particles are not the motes that we see in the path of a sunbeam ; for, when com- mon air is passed through a flame, these motes disappear, but the air still remains a good medium for fogs. It is a finer kind of dust which furnishes the fog and cloud nu- clei. The products of combustion are fog- producers, and especially the vapor from the burning of sulphur. Gem Minerals of Canada. — Although, ac- cording to Mr. George F. Kunz's paper on " Precious Stones, Gems, and Decorative Stones in Canada and British North Ameri- ca," Canada can hardly be called a gem-pro- ducing country, it furnishes a number of stones that are of more than passing interest to the mineralogist, and of some value in jew- elry and the arts. A number of gem minerals, not of gem quality, are found in examples of such size and perfection that they have been given prominent places in cabinets, and are even more prized as specimens than cut stones from other localities. Their mineral- ogical value gives them no small commercial importance. Of such are magnificent zircon crystals, occurring as individuals up to fif- teen pounds in weight, and many finer ones weighing a pound, as well as beautiful twin crystals of the same mineral ; black titanite in simple and trimmed crystals up to seventy pounds each ; " vast quantities of amethyst " from Lake Superior ; ouvorsovite or green chrome garnet from Orford, and white gar- net crystals from near Wakefield ; and apa- tite crystals, one weighing over five hundred pounds, of great beauty, of which the rich green variety, especially, would do to work into ornaments similar to those made from fluorite. Only a small part of the territory of the Dominion has been examined with reference to these stones ; and with the dis- covery of new localities important additions to the list may be anticipated. The Sliding Railway.— The Chemin de Fer GUssanl, or sliding railway, at the Paris Exhibition, according to a description by Sir Douglas Galton in the British Association, is based on the two principles of causing the carriage to slide on a thin film of water in- troduced between the sledge-plates on which it rests ; and the propulsion of the sliding train by horizontal columns of water acting through hydrants placed at intervals on the line. The system was originally designed by Girard in 1861, who made a line at his own private house, where he had an inclina- tion of one foot in twenty. The results he obtained seemed to justify the application of the system in special cases on a paying basis. He acquired a concession in 1869 for a rail- way from Calais to Marseilles, to which a subvention was afterward attached. But the War of 1870 resulted in the destruction of the railway by the German army, and in the death of M. Girard in 1871. In 1885 M. Barre purchased the drawings left by M. Girard, and introduced an improvement which he considered would make the system more workable. A line on this improved system was established in the Paris Exhibi- tion, about two hundred yards long, and trains were run upon it. Properties of the Kola-Nut. — Kola-nuts, or the seeds of Sterculia acuminata, are allied in composition to cocoa, coffee, and tea, but contain a relatively large amount of caffeine. They are credited with strong tonic and nervous stimulant properties ; with counter- acting and removing the sense of exhaustion after fasting and fatigue ; with having an- tagonistic reaction to alcohol ; and with a purifying influence on water. Their value as a therapeutic and dietetic agent has been tested by Surgeon R. H. Firth, who concludes that kola is not a food ; that it increases total urinary water, has a stimulant action on the nervous system, temporarily strengthens the NOTES. 863 heart-beat, and increases the arterial tension. In times of exertion and fasting it wards off the sense of mental and physical depression and exhaustion. The author has not gained positive results respecting its therapeutic qualities. Its action in purifying water is mechanical, and not more effective than that of other mucilaginous seeds. Raining Spiders' Wefts. — Falls or show- ers of gossamer spiders' webs have been re- corded in different parts of the world. White describes several in his "Natural History of Selborne." Darwin mentions a shower which he observed from the deck of the Beagle off the mouth of the Rio Plata, when the vessel was sixty miles from land. A general fall of spiders' webs is said to have been noticed a few years ago in some of the towns of Wisconsin, which seemed to come from over the lake. The webs were strong in texture, very white, varied from sixty feet in length to mere specks, and were seen as far up in the air as the power of the eye could reach. The shower may have been due to an unusual excursion of the familiar geometric spider, a species which has the same power as the gossamer of shooting webs that float upon the air, and sometimes serve aa an air-raft for the producer. NOTES. Thk scientific courses at Indiana Univer- sity, of which our contributor, David Starr Jordan, is president, include departments of physics, with classes in physics proper, phys- ical measurements, and meteorology ; chem- istry, with qualitative and quantitative anal- ysis, special work, and water analysis ; geol- ogy, with mineralogy, topographical geology, and field-work; zoology, with many classes, including theories of evolution, the critical study of Darwin's " Origin of Species," and original research; and botany, with six class- es and advanced and original work in the senior year on a special subject. Since it was opened 3,816 students have been taught in the college departments of the university. "Cocoanut day" is celebrated in most parts of India during the full moon in Au- gust. On that day numbers of nuts are thrown into the sea as an offering to the Hindoo god. Occasionally one meets with deformed nuts, consisting of the husks with small nuts having no kernel inside. The na- tives attribute this blighting to the tree-frog, which, by smelling the flower, can prevent the fruit from coming to maturity. A curious survival of customs was illus- trated in Lisbon some days after the funeral of the late King Luis of Portugal. A funer- al procession, composed of officers, military, and citizens, marched through the streets to places where platforms covered with black cloth had been erected. Four shields, on which were painted the royal arms, were borne aloft on long staves. On arriving at the platforms, the principal persons took their places upon them ; one of the shield- bearers, advancing to the front and chant- ing, " Weep, 0 Portuguese, for your king, Dom Luis I, is dead," dashed his shield to the ground with such violence that it was shattered. This was repeated at each plat- form, while the bells were tolled during the whole ceremony. The proceedings were closed with a requiem service. At the recent annual meeting of the Ra- tional Dress Society, Viscountess Harberton, the president, said that during the past year she had hardly met with any expressions of approval from women with regard to their present system of dress. Most of the re- marks she had heard had been denunciatory of the weight, discomfort, or dragging, or — particularly from young women — the cold when evening dress was worn. This was cheering, because it marked a growing real- ization of the uncomfortableness of present costumes. In the speaker's opinion, the only hope of reform lay in a radical change to some kind of dress having the clothing for the legs dual ; it should clearly follow the shape of the form it was meant to cover. According to Mr. R. Andree, our Indians use rising smoke as a means of giving sig- nals, and have a system of alternately smoth- ering the column and letting it rise freely for transmitting different messages. A sim- ilar method is used in New Guinea and Aus- tralia. The great variety of the messages communicated by drums in the Cameroons and other parts of Africa have been described in the " Monthly." The Gallas, south of Abyssinia, have drums stationed at certain points of the roads leading to the neighbor- ing states, at which watchmen are appointed to sound the alarm in case of threatened in- vasion. In New Guinea the natives learn from the rapidity and rhythm of the blows on drums what is happening — whether an attack, death, or a festival. The opinion is expressed by Mr. Elliot, in his last Meteorological Report for India, that the period of minimum sun-spots is as- sociated in that country with the largest and most abnormal variations of meteorological conditions and actions. Thus the snow was exceptionally heavy in the northwest Hima- layas in the winters of 1866, 18*76, and 1 8*7*7. The most striking and disastrous famines have also occurred near the mini- mum sun-spots, as those of Orissa in 1866, Behar in 1874, and Madras in 18*76-'V7. So, 864 THE POPULAR SCIENCE MONTHLY. too, with cyclone?, as at Calcutta in 1864, when sixty thousand people were drowned in the storm-wave, and Backerganj in 1876, when one hundred thousand were drowned. The experiment has been tried in Mos- cow, Russia, with success, of using carrier- pigeons to convey negatives of photographs taken in a balloon. The plates were packed in light-proof papers and tied to the feet of pigeons, who speedily took them in good or- der to the station on the ground. Medical geology and climatology are mentioned by the " Lancet " as departments of the science to which more attention might be paid than is. Their usefulness is illus- trated by tbe recently published studies of Mr. Alfred Haviland on the distribution of cancer in the British Islands. The undue increase in all the learned professions in Germany is the subject of a pamphlet by Prof. W. Lexis, of Berlin. All the theological faculties, except the Roman Catholic, are increasing "to an alarming extent." The average number of medical students for the whole empire — 2,675 — was increased in 1888-1889 by 2,344. If a pro- portionate increase takes place in the num- ber of licenses, the year's new doctors will rise from the average of 456 to more than 800. A prize offered by one of the Teach- ers' Associations for the best essay on the overcrowding of the learned professions and the means of remedying it, was given to two papers out of seventy-six sent in, which are to be published in a book. An apparatus for providing a steady plat- form at sea for guns, search-lights, telescopes, etc., was described by Mr. Beauchamp Tower in the British Association. OBITUARY NOTES. Ex-President Martin B. Anderson, who died at Lake Helen, Fla., February 26th, was a scholar who had made himself eminent in many fields of thought and activity. He was born in Brunswick, Maine, in 1815 ; was graduated from Waterville College, now Colby University, in 1840; studied theology; preached, taught, and served as editor of the "New York Recorder," a Baptist pa- per, till 1853, when he was chosen Presi- dent of the University of Rochester, where his after-life was spent. He instituted a course of lectures in intellectual philosophy, which were continued till he retired, in con- sequence of ill health, a year or two ago ; also a course of historical lectures ; and under the head of political economy he treated various questions affecting money, taxation, etc., and free trade and protection. His studies extended to questions of constitutional law, and covered the arts. He was prominent in all Baptist denominational enterprises, and served the State on several civil commissions. In fact, as the " Evening Post " well says, " he was one of those men who take all knowl- edge for their province, and never wearied of enriching his mind with stores of all de- scriptions, which he distributed with lavish impartiality among the students under his charge." Among the recent deaths of scientific men abroad are those of M. L. Taczanowski, of Warsaw, a distinguished ornithologist, author of a book on the birds of Peru ; M. Neumayr, of Vienna, geologist, who was not yet forty years of age; and M. Otto Rosenberger, astronomer, who had been con- nected with the observatory at Halle since 1831. "La Nature," of February 15th, men- tions the death of M. Buys Ballot, of Utrecht, one of the most eminent meteorologists of the time, at the age of seventy-three years. He gave much attention to the study of data for facilitating weather predictions — the movement of cyclones, the direct observa- tion of clouds, and all the " natural symp- toms of the weather." He propounded sev- eral meteorological laws or maxims which bear his name, and probably had an equal part with any other student in giving shape to the present system of observation and investigation in that science. Major Peter Egerton Warburton, whose name is associated with the hazardous but successful expedition which he made across Australia in 1873, died recently in Adelaide, in his seventy - sixth year. His exploring party Buffered terrible privations during their march, and were not heard of for twelve months. Major Warburton received the gold medal of the Royal Geographical Society and various honors in recognition of his contributions to our knowledge of Australia. Sir Henry Yule, an Englishman, emi- nent in geographical research, died Decem- ber 31st, in his seventieth year. In his an- notated edition of Marco Polo's travels he made contributions of the most valuable character to geographical and antiquarian lore. M. Eugene Deslongchamps, a French paleontologist, who died last December, was the son of another paleontologist, Prof. Eli- des Deslongchamps, was Professor of Zool- ogy and Paleontology at Caen, and was the author of several memoirs on the paleonto- logical fauna of Normandy. Dr. Karl Eduard Venus, an eminent German entomologist, died at Dresden, De- cember 13th. He was the founder of the Entomological Society "Iris" at Dresden. M. Gustave Hirn, an eminent French physicist, mathematician, and astronomer, died January 14th, in the seventy-fifth year of his age. He was the author of a work of considerable repute on the " Constitution of Celestial Space." IK.) INDEX TO VOLUME XXXVI. VOL. XXXVI. — 55 INDEX. ARTICLES MARKED WITH AN ASTERISK ARE ILLUSTRATED.
