In buying feeding~stuffs the farmer should understand both the general character of the material, and the source and general nature of the substances composing it. It is often as important to know that the desired ingredients are not furnished by oat hulls or other indigestible wastes as it is to know the amount of these ingredients. The terms nitrogenous and carbohydrate are too general to be used without modification in classifying feeding stuffs and the following four classes give a better grouping: Class I. Contain 30 per ct. to 45 per ct. protein and 50 per ct. to 60 per ct. carbohydrates: Cotton-seed meal, linseed meal and gluten meal. Class II. Contain 20 per ct. to 30 per ct. protein and 60 per ct. to 70 per ct. carbohydrates: Gluten feeds, Atlas meal,. dried brewer’s grains, malt sprouts, buckwheat middlings and peas and beans. “Reprint of Bulletin No. 166. 36 Report oF THE DEPARTMENT OF ANIMAL HUSBANDRY OF THE Class III. Contain 14 per ct. to 20 per et. protein and 70 per ct. to 75 per ct. carbohydrates: Brans and middlings from wheat and rye and some proprietary mixed feeds. Class LV. Contain 8 per ct. to 14 per ct. protein and 75 per ct. to 85 per ct. carbohydrates: Cereal grains, cerealine, hominy and oat feeds, corn and oat chops, corn bran, corn germ feed and chop feed in general. Hays and fodders belong here more nearly than elsewhere. Samples of feed have been collected during the past two winters and analyzed chemically, physically and often microscopically. Cotton-seed meal should be light yellow, a dark color usually indicating inferiority. Protem may range from 42 per ct. to 46 per ct. or more in good samples. Of 16 samples only two showed evidence of adulteration, but the price did not follow percentage of protein. Old, or pressure, process linseed meal and new, or naphtha ex- traction, process meal differ mainly in fat, the former containing three or four pounds more per hundred. Protein of new process meal is perhaps less digestible because of cooking. Nineteen samples were examined and all were good. One was somewhat low in protein with no sign of adulteration. Gluten meals consist mainly of hard or flinty portions of corn after bran, germ and part of the starch have been removed. They should contain at least 80 per et. of protein to be classed as meals and may go to 40 per ct. Two samples analyzed were good but the less nitrogenous sold for the higher price. The gluten feeds are a mixture of the meal with the bran and germs and are less rich in protein than the meals, ranging from 18.8 per ct. to 28.1 per ct. This marked difference seems to be quite constant between the brands, samples of Joliet and Diamond brands running low. . Malt sprouts are the dried shoots from germinated barley. But few samples were analyzed and these were found normal in com- position, with from 24.66 per ct. to 30.87 per ct. of protein. New York AGRICULTURAL EXPERIMENT STATION. aT Brewer’s grains are the barley grains from which the starch has been removed by growth and fermentation. In fresh state they contain too much water to justify paying a very large price. Dried they furnish about as much protein as the malt sprouts. Buckwheat middlings and other buckwheat products were found of good quality, but varied widely in protein content, the iniddlings and feed running from 24.8 per ct. to 33.7 per ct., while the single sample of “ ships” showed 33.75 per ct. protein, 9.2 per ct. fat. 3 Wheat brans were found pure, but not constant in composition, the protein ranging from 13.4 per ct. to 17.1 per ct., and the starch from 17.5 per ct. to 30.6 per ct. The mixed wheat feeds are combinations of the offals of wheat milling and showed only the natural variations. Wheat middlings, with one exception, proved normal in com- position showing only variations similar to bran and due to same cause, difference in milling processes. Middlings contain more protein, more starch, a little more fat and less fiber than bran and are more digestible. It would seem that preference should not be given the bran as a feed. Hominy feed or hominy chop consists of the hull, germ and part of the starch of corn grains; and contains less starch, about the same amount of protein and more fiber and fat than corn meal. The samples analyzed appeared quite uniform in composition, except Hudnut’s which contained seven per ct. more protein than the average. The average was about 10.5 per ct. protein, 46 per ct. starch and sugar and 7.75 per ct. fat. The prices were much less uniform than the percentages. In mixed feeds seems to lie the greatest danger from adultera- tion, a danger which is not entirely guarded against by chemical determination of protein and fat. Oat hulls are extensively used as adulterants in foods of this class. Prices were often equal to what would have bought whole corn and oats. In 26 cases out of 35 examined, the fiber content is larger than the average for whole 38 Report oF THE DEPARTMENT OF ANIMAL HUSBANDRY OF THE oats and much larger than could be given by any straight corn and oats mixture. Some of the feed must have contained at least 50 lbs. of oat hulls per hundred lbs. One oat feed was less digestible by nearly 12 lbs. than whole oats and by nearly 31 lbs. than maize, due largely to the indigestible character of the hulls. The introduction of oat hulls into any mixed feed therefore, in- creases the amount of indigestible — useless— matter. The material coming from whole grains is also of better quality, being made up more largely of protein and the easily digestible car- bohydrates. Reasons why the source and character of the carbohydrates should be carefully considered in classifying feeding stuffs, are given in full in the bulletin. 2 Patent foods made up of some simple feed stuff like middlings, corn bran, linseed meal, etc., with a small quantity of charcoal, sulphur, fenugreek, gentian, salt, iron compounds, pepper and other cheap drugs and condiments were found on sale in great numbers and at exorbitant prices, varying from $100 to $500 a ton. This is from $70 to $470 a ton more than the best of them are worth as feeds. Their value as medicines is problematical ; if anything, the same effect can be much more cheaply secured by buying the drugs and mixing with the feeds ordinarily used in the stable. INTRODUCTION. i Commercial cattle foods are an important factor in the animal husbandry of this State. Few farmers, especially dairy farmers, produce all the grain they feed to their stock, for the winter ration generally includes one or more of the by-product feeding stuffs, usually of a more highly nitrogenous character than the home raised grains. Doubtless these purchased materials are often used with profit, while on the other hand, the opinion is freely expressed that it would be economy for many farms to be more fully self-supporting in the matter of the supply of cattle foods. However this may be, it is entirely probable that commercial New York AGRICULTURAL EXPERIMENT STATION. 39 feeding stuffs, more particularly those of the highly nitrogenous kinds, will continue to hold their place in the ration, and for this reason it is desirable, even essential, that the purchasers of these commodities shall have an intelligent understanding of their character and value. It is not surprising that the feeding stuff market is an object of perplexity, as it appears to be, to the majority of would-be buyers. The whole grains as such and as mixed with certain waste products, oil meals, the gluten feeds and meals, breakfast food wastes, brewer’s wastes and the so-called patent foods, besides the combination of a variety of materials, good and poor, under the name of “ mixed feeds,” are all urged upon the attention of the agricultural public. Such a variety of appearance, composi- tion and price must be considered that even the wisest may well hesitate before deciding what articles can be chosen most suitably and economically for a particular use. In view of the situation as thus outlined, and in order to pre- sent certain facts which have been gathered relative to the feed- ing stuff market in New York, besides paving the way for the largest benefit which may accrue from the new feeding stuff law, it is deemed wise to issue this bulletin. Many of the facts stated are by no means new, and some of the analyses are but a repeti- tion of previous results, yet it is felt that the situation justifies the statement of what is to some extent already familiar knowl- edge. INFORMATION WHICH THE BUYER SHOULD POSSESS. The farmer who wishes to buy a feeding stuff to supplement his home supply of grains should, first of all, understand the general character of any material to which his attention is called, 7. e., he should know whether it belongs to the carbohydrate or nitrogenous class of feeding-stuffs. To the man who is well informed, the trade name is generally indicative of composition. It is true, however, that new materials are constantly appearing in the market and trade names are some- 40 Report oF THE DEPARTMENT OF ANIMAL HUSBANDRY OF THE times deceptive, so that it will be a distinct gain when commercial cattle foods are branded with their real percentages of protein and fat, as presumably will be the case in New York under the operation of the new feeding stuff law. Moreover, buyers should understand something of the source and general nature of the waste products which make up a large proportion of our commercial feeding stuffs. The fact that any material is an offal from a manufacturing process may or may not mean that it is of inferior nutritive value. As an illustration, certain parts of the maize kernel which appear in the gluten meals and hominy wastes are from the parts of the grain in no way inferior, whereas oat hulls are the least valuable part of the seed. These facts establish an important distinction between the by- products from starch and glucose manufacture and those from the manufacture of breakfast foods from oats. For this and similar reasons, the ingredients of the various mixed feeding stuffs should be clearly stated for the buyer’s benefit, and the provision of our new feeding stuff law which, among other things, makes illegal the abominable practice of adulterating corn meal with oat hulls, without the knowledge of the purchaser, to be sold to him as mixed feed from corn and oats, is a step in the direction of en- forced honesty in the cattle food trade. CLASSIFICATION OF FEEDING STUFFS. Cattle foods are often classified in a popular way as “ carbohy- drate” and “nitrogenous.” Such a division into two classes, based upon the proportions of carbohydrates and protein, is not rational. The fact is, there is a quite uniform gradation in the percentage of protein in feeding stuffs from cotton-seed meal to wheat straw and there seems to be no natural point of separation into two groups. It is absurd to place wheat bran with 16 per ct. of protein in the same group with cotton-seed meal with 45 per et. of protein. New Yorx AcricutturaL Experiment SraTIon. 41 As a matter of convenience and a nearer approximation to accuracy, it seems advisable to classify feeding stuffs into at least four groups and even with this arrangement the range of com- position within any one group is quite wide. The following are the classes suggested, with some of their principal members: Class I. 30 to 45 per ct. protein and 50 to 60 per ct. carbohy- drates, including cotton-seed meal, linseed meal and the gluten meals, such as the Chicago, King, Cream and Hammond. Class II. 20 to 80 per ct. protein and 60 to 70 per ct. of car- bohydrates, including gluten feeds, such as the Buffalo, Golden, Diamond, Davenport, Climax and Standard, as now made, Atlas meal, dried brewer’s grains, malt sprouts, buckwheat middlings and peas and beans. Class IIT. 14 to 20 per ct. of protein and 70 to 75 per ct. of carbohydrates, including brans and middlings from wheat and rye, certain so-called mixed feeds of a proprietary character, these being in part oat feeds fortified with some more highly nitrogenous material. . Class IV. 8 to 14 per et. of protein and 75 to 85 per ct. of carbohydrates, including barley, corn, oats, rye, wheat, cerealine, hominy and oat feeds, corn and oat chop, corn bran, corn germ feed and chop feed in general. The hays and other fodders belong in Class IV more nearly than in any other. ANALYSES AND COMMENTS. THE SAMPLES AND THEIR EXAMINATION. The samples, the analyses of which appear in this bulletin, were mostly selected in this State during the past two winters by authorized representatives of this Station. In a majority of cases the selling prices are given, these being the ton prices stated to our agent by the dealers where the sample was procured. It is 42 Revort or Tre DEPARTMENT or ANIMAL HUSBANDRY OF THE to be noted that the names of manufacturers are not given in connection with various samples. As many of the goods were not branded by the name of the maker or importer, it was thought best, in order to avoid possible error, to consider the samples wholly from the standpoint of what inspection has shown them to be. These samples were submitted to more than the usual chemi- cal analysis,— they were carefully examined as to the nature of their constituents, special attention being. given to the feeds of a mixed character and to those coming under the head of proprie- tary or condimental foods. Moreover, the chemical analysis has been made to include even more than usual. In the case of the mixed and chop feeds the amount of fiber present is often suggestive as to the origin of their constituents and besides it is interesting and useful to know to what extent, especially in the corn and oat offals, the starch and other equally valuable carbohydrates have been removed. COTTON-SEED MEAL. This feeding stuff is a by-product of the manufacture of cotton- seed oil. The seed of cotton, after the long fibers are removed by ginning, consists of a kernel enclosed by a thick hull. This hull, after removal, constitutes a low grade feeding stuff which is known in the market as cotton-seed hulls. The hulled kernels are crushed and after they are cooked the oil is removed by pressure, leaving a cake residue, nearly 800 pounds from a ton of seed, which after grinding we know as cotton-seed meal. The color of this meal should be light yellow and it should have a clean nutty flavor. The percentage of protein in the best product generally ranges between 42 per ct. and 46 per ct. Among the causes of inferiority are the presence of hulls and injury due to fermentations, but these conditions are indi- cated by the color and flavor. Dark colored cotton-seed meal should be regarded with suspicion. New Yorx AaricutturaAL Experiment Srarion. 43 SAMPLES OF CoTrron-SEED MEAL COLLECTED IN NEw YorK Durina 1898 AND 1899.

Two samples, Nos. 439 and 705, showed so low a protein content as to justify the con- clusion that they were from adulterated stock. They were dark colored. There is no question that adulterated meal is in the market, as is clearly proven in Bulletin No. 56 from the Massa- chusetts Experiment Station, where the analyses are given of 44 Report oF THE DEPARTMENT OF ANIMAL HUSBANDRY OF THE eighteen samples of inferior goods found in the market of that State. This adulteration is probably brought about by grinding in hulls. These meals were sold in part under the name Sea Island Cotton-seed and probably were in all cases a mixture of the yellow meal and finely ground hulls. Farmers should avoid such goods. The sample of cotton-seed feed No. 552, the analysis of which appears in the above table as a means of contrasting it with cotton-seed meal, consists of cotton-seed hulls and is very inferior in value. LINSEED MEAL. Linseed meal is a by-product from the manufacture of linseed oil. It is often called oil meal. “ Old process” oil meal is that from which the oil is obtained by pressure and “ new process ” meal is the residue afer treating the crushed seed with a light naphtha. The former contains the more fat although owing to a change in the process the “old process” meal contains less fat than was formerly the case. By the older methods about 35 lbs. of oil was obtained from 100 lbs. of seed, but now the output is larger. The relative value of “old process” and “ new process” meal is much discussed. Certainly there is no appreciable difference in palatableness and healthfulness, and no large difference in nutritive qualities. The protein of the latter appears to be some- what less digestible, due doubtless to the increased cooking to which the new process product is subjected.

These differences appear to pertain more largely to brands than to samples, the Joliet and Diamond brands falling considerably below the others in protein content. How- ever this may be, the facts as given are a good illustration of the need of branding commercial feeding stuffs with a statement of their composition, for unless this is done a gluten feed passes for such without the buyer having a definite knowledge of what it really is, and besides, this class of materials is often confounded with gluten meals which are of superior value, both as to com- position and digestibility. BREWERS AND DISTILLERY RESIDUES. The so-called brewer’s residues are those resulting from the operations of malting and brewing. In malting, the barley grains are allowed to sprout, and before the malted grains are crushed for brewing purposes these sprouts are removed, which in an air dry condition are known in the market as malt sprouts. From the malted grains is extracted the sugar that has formed from the starch during the germination which has occurred, and these extracted grains after drying appear in the market as dried brewer’s grains. They are much poorer in starch and richer in protein than the entire barley grain and are properly regarded as a nitrogenous feeding stuff.

But few analyses have been made in this country of distillery waste. No. 724 was obtained from a distillery at Waterloo and in the fresh condition is somewhat used by farmers in the immediate vicinity. It is to be noted that the proportion of dry matter in the fresh material is very small, only 8.7 per ct. or one-tenth as much as in the ordinary grains in an air dry condi- tion. The cost should be only one-tenth also. This observation applies in a general way to the fresh brewer’s grains which proved to be nearly three-quarters water. BUCKWHEAT MIDDLINGS. There are several offals from the milling of buckwheat, includ- ing the hulls, the bran and middlings. The latter contain a generous proportion of protein, usually not less than twenty-five, and they are properly classed among our nitrogenous feeding stuffs. Oftentimes the bran and middlings are mixed together when the percentage of protein is, reduced in proportion to the 4 50 Report or tHe DEPARTMENT OF ANIMAL HusBanpry OF THE amount of bran present. ‘The bran contains from 10 per ct. to 12 per ct. of protein and the hulls from 3 per et. to 5 per ct.

There has appeared in the feeding stuff trade during recent years a class of materials which, as a rule, are mixtures either of some cereal grain with certain manufacturers’ by-products or of two or more by-products. To these are applied a variety of names, often of a proprietary character, some of which give no hint of the nature of the mixture, and others, if taken for their face value, indicate the sources of the ingredients. If these mixtures were always made up wholly of high grade materials, they would need less attention than they now really demand. As a matter of fact, many of them are found to contain a con- stituent of very inferior value, viz.: oat hulls, a by-product from the manufacture of breakfast foods. Not only have large manu- facturing establishments used these hulls in compounding mixtures, but some local millers in the State of New York have bought them to grind with corn and sometimes with mill wastes, “mixed feed,” “corn and oat the mixed product being sold as feed,” “chop feed,” and so on. To quite an extent, at least, farmers have been ignorant of the real nature of these feeds, and as this Station has abundant evidence, have paid for them prices equal to the cost of whole corn and oats. If our millers have been aware of the inferiority of oat hull mixtures, and have sold such goods to consumers who were ignorant of what they were buying, it is charitable to say no more than that the rules of an honorable business policy have been severely violated. In order that there may be no misapprehension as to the real character of oat hulls, attention is called to their composition and their relation to the kernel. It was found at the Ohio Experiment Station that with 69 varieties of oats the hull constituted from 24.6 per ct. to 35.2 per ct. of the weight of the grain, the average being 30 per ct. From other sources we learn what is the composition of the dry matter of the whole grain, the hulls and the hull-less kernels. 56 Report oF THE DEPARTMENT OF ANIMAL HUSBANDRY OF THE ANALYSES OF OATS, OAT HuLLS AND OAT KERNELS.

It is to be noted in the first place that the prices of these various mixed feeds are in many cases fully equal to what a mixture of whole corn and oats would have cost at the time the samples were taken. This being so, it is fair to inquire whether the by-product com- binations of the class we are discussing are equal in value to the entire cereal grains. The principal fact to be considered in this connection is that nearly all of the feeds mentioned above contain a generous proportion of oat. offals, largely hulls. This is shown in two ways, viz.: by the high proportion of woody fiber and by the low protein content. Oats contain more fiber than any other New York AGricuntuRAL EXPERIMENT STATION. 59 cereal grain except buckwheat, the average percentage in thirty samples of American oats being 9.5 per ct. In 26 cases out of 34 the fiber content of- these mixtures, as shown above, is larger than that in average oats and in 16 in- stances it ranges between 11.0 and 29.7 per ct. Moreover, a majority of these feeds contain quite a proportion of corn, or perhaps hominy waste, material, which has a very low fiber con- tent, averaging not over 2 per ct. It is clear that a mixture of the entire grains of corn and oats which does not carry less fiber than the oats, is impossible, and inversely it is equally plain that combinations of corn and of oat offals with as large and generally much larger, percentage of fiber than is found in pure oats must contain more oat hulls than belong with the oat kernels present, That this is true of many of these feeding stuff mixtures is shown by a mere mechanical examination without resorting to a chem- ical analysis. Some of them must contain not less than 50 Ibs. of oat hulls per hundred pounds. The low proportion of protein is also evidence of a convincing character. In 20 out of the 34 samples, the protein content is below what would ever be the case with a mixture of whole corn and oats, a condition which is brought about by the small proportion of protein in the oat hulls present. In certain brands an amount of some highly nitrogenous feeding stuff like cotton-seed meal or gluten meal is found, the object of its use being to bring up the protein content to the standard of wheat bran. This certainly improves the feed, but at the same time the presence of high quality ingredients adds nothing to the value of the inferior constituents. Grinding corn with oat hulls, for instance, may not injure the corn but it does not improve the hulls. They are still hulls and retain all their characteristics as a feeding stuff. In order te ascertain the effect upon digestibility of introducing oat feed into a feeding stuff mixture, an experiment has been con- ducted at this Station with sheep, using as the experimental feed- 60 Report or THE DerparTMENT or ANIMAL HUSBANDRY OF THE ing stuff an oat feed sold in the State of New York.

Besides, the material coming from the entire grains is of better quality, being made up more largely of protein and the easily digestible carbohydrates. THE CARBOHYDRATES OF MIXED FEEDS AND OTHER FEEDING STUFFS. The superiority of the dry matter of the cereal grains over that of the coarse fodders is generally recognized. This fact is due to two causes, viz: (1) The greater extent and (2) the greater ease of digestion of the grains as compared with the fodders. In this connection the carbohydrates are of first importance, in point of quantity at least. These compounds differ among themselves in their digestibility to a marked extent. The sugars and starches, under normal conditions are promptly and completely digested, while the gums, fiber and other less well known substances are New Yorx AGricutturaL Experiment Station. 61 only partially dissolved in the digestive juices. It follows, then, other things being equal, that the larger the proportion of starch and sugar in the nitrogen-free extract of a feeding stuff the more completely is it digested. It also follows that when any manufacturing or other process reduces the proportion of sugars and starch in any grain or other material, the digestibility, and consequently the nutritive value of its non-nitrogenous part, is diminished. We have good rea- son for believing too, that the net value of that which is digested is less than would be the case if the proportion of starch and sugar had not been reduced. While the digestion products of fiber and gums are undoubtedly oxidized quite fully and perhaps furnish to the animal their full calorimetric value (except a small proportion of expiratory methan supposed to come from the fiber) the elaborate researches of Zuntz leave little doubt that their net value is less than digested sugars and starch. This is because the work of mastication and digestion of the former is greater. As a matter of illustration we may refer to the great superiority of corn meal over timothy hay in point of digestibility, the ex- planation of which is in accordance with the facts just stated. The nitrogen-free extract of maize is mostly starch, the accom- panying fiber being insignificant in amount whereas in timothy hay there is found a small proportion of sugars and starch, while gums, fiber and other less digestible compounds are abundant. Moreover, because of the more resistant qualities of the hay to mastication and propulsion along the alimentary canal, it costs more to digest it than is the case with maize and other grains. Practice recognizes these facts in its estimate of the grains as against the fodders. 62 Report or Tur DerpartMENT oF ANIMAL HUSBANDRY OF THE The point of this discussion will be seen when we come to con- sider the figures in the following table.

In the case of the one sample of gluten meal examined the starch still constituted a large proportion of the nitrogen-free extract. The chop feeds and other similar combinations contain as a rule quite a proportion of corn, that furnishes nearly all the starch which is found in these mixtures. Such materials as the X Oat Feed and New York AqricuLtturRAL Experiment STarTion. 63 oat chop No. 542 have in them but little starch, these being nearly pure oat offals. These facts are in harmony with the outcome of digestion ex- periments, from which we learn that the nitrogen-free extract of the whole grains is much more digestible than that of most of the manufacturing wastes which come from them, as can be seen by the figures in the right hand column of the above table. Some “mixed feeds” apparently are compounded and advertised on the assumption that feeding stuffs are to be compared in value solely on the basis of their percentage of protein and fat. This is a false basis. The quality of the accompanying carbo- hydrates must always be considered. For instance it would not be difficult to simulate the composition of corn meal or of wheat middlings by mixing oat hulls with some of the old style linseed meal, adding a little crushed linseed to make up the deficiency of fat. But would the mixture equal corn meal in value? By no means. In one case the protein and fat would be associated with woody fiber in large proportion, and in the other case with little else than starch. The net value of the corn meal would be much above that of the mixture as measured by the extent and labor of digestion. It is quite clear to the writer that those teachers who publish tables or estimates of feeding stuff comparative values based wholly upon the protein content are misleading the agricultural public and furnishing to manufacturers a justification for false claims. The relation of oat offals to one class of feeding stuffs has been discussed somewhat at length, because it is proper for farmers to understand its significance. They have a right to know the nature and value of what they are buying, a statement to which no legitimate trade interest will take exception. MISCELLANEOUS FEEDING STUFES.

Rye feed, about which questions are frequently asked, corre- sponds quite closely in composition to wheat offals. New Yorx AGRICULTURAL EXPERIMENT STATION. 65 Attention is called to the low protein content of certain feeds which are refuses from starch manufacture. These are not unlike corn meal in the proportion of their constituents and should not be confounded with gluten meals and feeds. The composition of clover hay is not modified by erinding. So long as cut clover hay is fed successfully to poultry the advantage of paying from $20 to $30 or more per ton for having it ground is not clear. | CONDIMENTAL FOODS. There is found very prevalent in our markets a class of sub- stances bearing the term “food” that are noted chiefly for being sold in small packages at remarkable prices, on the strength of claims which are sometimes startling even in this time of daily miracles as set forth in the advertising columns of our newspapers. These proprietary wonders are usually marvelous both in their nutritive and their healing effects, for if one may believe the statements concerning some of them, they are remarkably loaded with nutritive energy and the diseases they will not cure would be highly interesting to the veterinarian as pathological novel- ties. It is most surprising to find after being told that the effect of these “foods” is to enrich milk, produce bovine obesity with remarkable rapidity and banish disease, that so far no one of them has been examined that is not made up largely of some common grain product mixed with more or less of the commonest of drugs and other substances having little curative value, nearly all of which of any merit whatever may be found on the pantry ‘shelf or in the horse stable of many farms. It is strange, too, that farmers have not long ago discovered for themselves, if it is true, that when bran or some other common feeding stuff is com- pounded with the equally common charcoal, salt, sulphur, salt- petre, fenugreek, etc., the nutritive power of the food is greatly enhanced and the drug takes on unheard of curative properties. Nevertheless we are asked to believe that such is the case. No 5 66 Report or rut DerartMent or ANIMAL HusBanpry OF THE evidence of the accuracy of these unusual properties is furnished, save the usual list of testimonials, the reliability of which may be judged in the light of the fact that some of the most absurd im- positions ever perpetrated on the public have been abundantly approved by similar evidence. Years ago, Lawes & Gilbert con- demned patent foods at the prices for which they are sold, and important experiments conducted in recent years have not fur- nished the least justification of their purchase by stockmen, Farmers may accept with perfect confidence this statement, viz.: that there are no nutritive properties, compounds or influences yet discovered which are not possessed by the common feeding stuffs, neither is it possible to increase for well animals the nutritive effect of protein and carbohydrates by associating with them any compounds or drugs whatever. As to the medicinal value of condimental foods, it may be safely asserted that well animals, properly fed, need no medicine, and sick animals should receive treatment specifically adapted to their ailments. Universal preventives and curealls of diseases are un- known and are believed in only by those who are ignorantly cred- ulous. More than this, many of the constituents of condimental foods have no recognized curative value. But notwithstanding all that has been said again and again to the farming public concerning condimental foods, they still find a sale. Not less than fifteen brands have been examined at this Station during the past two years, all of which were found in the New York markets. Their analyses from a food standpoint follow.

The special ingredients added ostensibly for medicinal effect, were found to include charcoal, fenugreek, gentian, sulphur, salt, saltpeter, sodium sulphate, iron compounds and pepper. Particular attention is called to the prices at which these “foods” are sold. The range is from $100 te $590 per ton, which is at least from $70 to $470 per ton more than the materials are worth for food purposes. It may be claimed, as some of the manufacturers urge, that these mixtures should be regarded as medicines. Even if this is true the farmer who wishes to ad- minister any of these common substances to his animals can do so at a small fraction of their cost in condimental foods by purchasing them as drugs and then mixing them with the grain ration as he wishes. For the promoters of these mixtures to claim that they have any knowledge of compounds and compeunding not common to veterinary medicine is charlatanism in its most offensive form. Blatchford’s calf meal is advertised as a food of great value. * Mostly sulphur. 68 Report oF THE DeparTMENT OF ANIMAL HUSBANDRY OF THE Director Woods of the Maine Station gave this product a careful examination and his report concerning it includes the following statements. “These goods were sent to an expert on food mixtures and adulterations at the Connecticut Experiment Station who reports as follows: ‘I have examined Blatchford’s calf meal under the microscope and find it contains linseed meal, some product from the wheat kernel, some product from the bean kernel and a little fenugreek. The linseed meal appears to be the chief constituent. The wheat product is bran, middlings or some similar product con- sisting of starchy matter mixed with more or Jess of the seed coats. Bean bran was present in considerable amount and more or less of the starchy matter.’ “Tn a letter just at hand from Mr. J. Barwell, the proprietor of these goods, he says: ‘ Regarding the ingredients, I cannot give you the exact constituents of it, but I may say that it is composed mostly of locust bean meal with leguminous seeds such as lentils, etc., and oleaginous seeds such as flax-seed, fenugreek and anise seed, all cleaned, hulled and ground together and thoroughly well cooked. There is no cheap mill food and no low grade feed enters into this composition. I am prepared to go into any court in the United States and make an affidavit that there is no farmer in the United States that can compound Blatchford’s calf meal for less than $3.50 per hundred.’ “Locust bean meal which Mr. Barwell claims to be the chief constituent of Blatchford’s calf meal is practically not used in this country as a cattle feed. The average of ten English and Ger- man analyses show it to carry: Water, 14.96 per ct.; ash, 2.53 per ct.; protein, 5.86 per ct.; crude fiber, 6.39 per ct.; nitrogen- free-extract, 68.98 per ct.; fat, 1.28 per ct. “It is evident from the chemical analyses that locust bean meal ean not be the chief constituent of Blatchford’s calf meal, but that the microscopist is correct that linseed meal is the chief constituent. Locust. bean meal has only six per cent of protein and in order to make a mixture carrying from twenty-six to thirty-three per ct. New Yorx AcricunrtTuRAL Experiment Sration. 69 of protein it would be necessary to add large quantities of goods like linseed meal rich in protein. As seen from the analyses Blatchford’s calf meal has a feeding value somewhat inferior to old process linseed meal. Whatever it may cost to manufacture, no man who has sufficient intelligence to mix feeds can afford to buy it at anything like the price asked.” In the light of this information the farmers of New York must decide whether they can afford to pay at the rate of $100 per ton for materials no more valuable than those which are generally offered in our markets at ordinary prices. Special mention is made of this feed because it is sold for distinctively food purposes and because, prices considered, it perhaps does the farmer’s pocket- book as little harm as any other food mentioned in the above list, and less than all excepting No. 462. At the same time it typifies all those efforts here discussed of mixing common ma- terials and selling them under extraordinary names at extraordinary prices. CONCENTRATED FEEDING STUFFS LAW.

Of two rations which contained practically the same proportions of the ordinarily considered groups of constituents, but different amounts of mineral matter, one wholly of vegetable origin proved much inferior for growing chicks to the other ration, higher in ash content, containing animal food. When the deficiency of mineral matter was made good by the addition of bone ash, the vegetable food ration for chicks equalled or somewhat surpassed in efficiency the corresponding ration in which three-eighths of the protein was derived from animal food. For laying hens the rations containing animal food proved superior to others in which all the organic matter was derived from vegetable sources. The vegetable-food ration supplemented by bone ash proved equally efficient for limited periods. Rations containing animal food proved very much superior for ducklings to rations of vegetable origin which had, according to the ordinary methods of estimation, practically the same nutritive value. A ration of vegetable food supplemented by bone ash proved much inferior to another ration of similar ‘“ composition ” in which three-eighths of the protein came from animal food. INTRODUCTION. Information about foods is one of the first essentials in poultry keeping. A very important part of this information concerns the necessity or economy of using animal food. The need for data * Reprint of Bulletin No. 171. 76 Report or tHe Department or ANIMAL HUSBANDRY OF THE upon this subject has led to a number of feeding experiments at this station. Aside from the usual increase in cost of food no results have discredited the moderate use of animal food from healthful sources. In general, rations entirely of vegetable origin have proved much Jess efficient than corresponding rations which contained animal foods. But it appears that the inferiority is due in some instances more to the lack of sufficient mineral matter than to the less efficient forms of .the other food constituents. The data from some of the preliminary feeding trials were pub- lished in Bulletin 149. The rations then fed contained equal amounts of protein; but in part of the ration from two-fifths to one-half of the protein was from animal food, while in contrasted rations it was derived mostly from vegetable sources, although some came from milk curd. Subsequent experiments have cor- roborated the results then obtained and added to their significance by furnishing supplementary and more extended information. In one series rations in which about 19 per ct. of the dry matter and 37 per ct. of the protein came from animal food proved superior to rations containing an equal amount of protein derived entirely from vegetable food. The rations were similar in nutri- tive ratio but the one in which animal food was used contained more than twice as much mineral matter and somewhat more fat. Tn another series the deficiency of mineral matter in the one ration was made good by the addition of bone ash, so that the propor- tions of protein, ash and fat were alike in the contrasted rations. With this addition a ration of vegetable food was as efficient during certain periods for chicks and hens as a ration containing animal food. For ducklings the vegetable-food ration was thus improved but still did not approach in efficiency the animal food ration. FIRST SERIES OF EXPERIMENTS. Tn this series of experiments ten lots of chicks were fed for ten or twelve weeks and four combined lots afterward for either four New York AGRICULTURAL EXPERIMENT STATION. i or ten weeks, two lots of laying hens were fed for six and one- half months and two lots for seven and one-half months, and two lots of ducklings for ten weeks. Experimental feeding commenced with the chicks and ducklings when they were one week old and continued until they were ten and twelve weeks old. They were all hatched in incubators and reared in brooders. A small out- door run on bare ground was allowed each lot. Occasionally a chick escaped through the fence into outside flocks where it could not be identified and was dropped from the lot. In a few lots (Lot VII especially) there was considerable loss at one time from sunstroke caused by accidental exposure. Allowance was made for any loss caused by accident, obviously uninfluenced by feeding. The weight of any that died was accounted in the rec- ord as loss in live weight when estimating the food cost per pound gain. RATIONS. One ration for chicks and hens consisted of wheat, cracked corn, barley, oats and a mixture (No. 1) composed of 14 parts by weight corn meal, 11 parts animal meal, 2 parts each of ground oats, wheat bran and pea meal, and one part each of wheat mid- dlings, O. P. linseed meal, malt sprouts, brewer’s grains and glu- ten meal. The contrasted ration consisted of wheat, barley, oats and a grain mixture (No. 2) composed of 7 parts each of pea meal and wheat bran, 6 parts of O. P. linseed meal, 4 parts of gluten meal, 3 parts each of corn meal and ground oats and 2 parts each of malt sprouts, brewer’s grains and wheat middlings. One pound of salt was added to every 360 pounds of each mix- ture. Each ration for ducklings contained, with one of these mixtures, wheat bran, corn meal and ground oats. The animal food used in these experiments was the dried and ground animal meal. Dried blood, fresh bone, beef scraps and pork scraps have often been fed at this Station, but owing to the 78 Report oF THE DEPARTMENT OF ANIMAL HusSBANDRY OF THE inferior palatability of some grades of dried blood and the poor keeping qualities or continual variations in composition of differ- ent lots of the other foods, they were not so suitable for use in these experiments. . Green alfalfa was fed to all lots. Oyster shells and grit were fed to the hens and sand and coarse grit to the chicks and duck- lings. VALUATION OF FOODS. + In estimating the cost of the foods the same valuations have been assumed, for convenience of comparison, that had been used in the preliminary series of experiments, although they are most of them lower than the present market prices and those that existed during part of the last series of experiments. Wheat bran, wheat middlings, corn meal, malt sprouts and brewer’s grains were rated at $13 per ton, pea meal at $13.50, buckwheat middlings at $14.40, ground oats at $16, linseed meal at $20, gluten meal at $23, ground flaxseed, bone ash and animal meal at $40 per ton. Corn was rated at 40 cents per bushel, barley at 39 cents, oats at 26 cents, and wheat at 80 cents. Alfalfa hay was rated at $10 and green alfalfa at $2 per ton. In these experiments the cost of the ration could only be a secondary consideration; but only ordinary foods were used and the relations between valuations is a natural one, similar to what would generally exist between rations of vegetable and mixed origin. The data in regard to the food cost of growth are there- fore important. The food used in the first series of experiments had the aver- age composition’ shown in the accompanying table. 1 Most of the analyses of foods used in these experiments were made by Mr. J. A. Le Clere. Some ash analyses were made by Mr. W. H. Andrews. Very much of the credit is due to Mr. P. F. O’Neill; for the successful control of the experiments has been dependent on his careful and skillful management.

B.3} EXPERIMENT WITH CHICKS. In two lots of this series of experiments the chicks were two weeks old when the experiment began, in all the others one week old. Lots I, III, V, VII and IX were fed the ration containing animal meal and Lots II, IV, VI, VIII and X were fed the con- trasted ration. At the start Lot I was similar in every way to Lot IJ. The same was true of Lots III and IV, V and VI, VII, and VIII, and IX and X. After the first four lots had been fed for eight weeks the cockerels were removed and a number of pullets from Lots I and III were fed for ten weeks in comparison with an equal number from Lots II and IV. Later, chicks from Lots V and VII after removal of many of the cockerels were fed together in comparison with others from Lots VI and VIII. The chicks in Lots I and II were Leghorns, those in III and IV mostly Leghorns with a few Wyandottes. Half of those in Lots V, VI, VII and VIII were Leghorns and half Wyandottes and crosses. In Lots IX and X somewhat more than half the chicks were Wyandottes and crosses and the remainder Leghorns. The records of feeding and statements of the results follow in tabulated form, the averages in most cases being for 14-day periods. 80 Report oF THE DEPARTMENT OF ANIMAL HUSBANDRY OF THE "Qq510oM | am st = © ur ure3 punod yovo | © .- $ 4 Joy pooy uy aoqqear Auq | =“ w OO FF ‘qquajea upuyeSjeupunoa | gg "= © %& | yous JoJ pooy Jo ys0g| HA H+ 7 Ww | | | *pey IysiomM gil = “60 fons So eal] punod yove 103 ABp im eS : F con pooy uy soyeur Aiq| ON SA “ A | | 1 i3 i | 5 io | ce lor) or) ‘poizad Sump yoyo aed | Z| . : : qq31em ul mes esueay| ON © 1 10 if *£ep 3 a pooy jo ysog!| O 04 07 .09 ul r3 ‘ep sed % mn 2 8 = pooy ul zoqqeut Auq| 6 eit icy H | 3 | " eb OR Ny a os 5 | Aep aod pooj [v}0, | oO at) pace - | 3 & a + = | "O1yed BAT} Sa eye eps Bee Tajnu ejyeuisoiddy | ™ a <= ; | a ll al re | = | | S = | e.g aes ah jie. ‘pooyursyeq | 8 mie’ Grou = = = ' ie} eo [ml | i 8 | H © e; | *pooj Ul ys N : !

More food was eaten by the chicks having the ration contain- ing animal meal. Calculated on the basis of dry matter the food consumption for Lot I was 12 per ct. greater than for Lot II and the gain in weight 37 per ct. greater. Lot I gained one pound for every 3.6 pounds of dry matter in the food and Lot IT gained one pound for every 4.3 pounds of dry matter. Lot III consumed 24 per ct. more food than Lot IV and made 22 per ct. greater gain in weight. The dry matter in the food consumed for each pound gain in weight was about 4.3 pounds for Lot III and 4.4 pounds for Lot IV. During the following ten weeks when pullets from Lots I and III were fed in comparison with those from Lots II and IV the consumption of food under the animal meal ration was 26 per ct. greater and the gain made was 538 per ct. greater. The dry mat- ter in the food for each pound gain was 6.6 pounds for Lots I and III and 8.1 pounds for Lots II and IV. The food consumption of Lot V was 26 per ct. greater than that of Lot VI and the gain in weight 45 per ct. greater. The dry matter in the food for each pound gain in weight was 4.3 pounds for Lot V and 5.0 pounds for Lot VI. The food consumption of Lot VII was 24 per ct. greater than that of Lot VIII and the gain in weight was 45 per ct. greater. The dry matter in the food for each pound gain in weight was 4.3 pounds for Lot VII and 5.0 pounds for Lot VIII. During the four weeks that pullets from Lots V and VII were fed in comparison with those from Lots VI and VIII, 37 per et. more food was consumed under the animal food ration than un- der the other, and the gain in weight was 54 per ct. greater. The dry matter in the food for each pound gain in weight was 3.5 pounds for the former lots and 4.3 pounds for the latter. The food consumption of Lot IX was 34 per ct. greater than that of Lot X and the gain in weight more than twice as great. The dry matter in the food for each pound gain in weight was New York AGRICULTURAL ExPERIMENT STATION. 91 4.4 pounds for Lot 1X and 6.8 pounds for Lot X. During four weeks after the cockerels were removed Lot X consumed about 5 per ct. more food than Lot IX but the latter made 24 per ct. greater gain in weight. The dry matter in the food for each pound gain in weight was 5.1 pounds for Lot IX and 6.5 pounds for Lot X. During the following four weeks about 14 per ct. more food was eaten by Lot IX and only about 4 per ct. greater gain made. The dry matter in the food for each pound gain was about 5.6 pounds for Lot IX and 5.2 pounds for Lot X. RELATIVE ECONOMY OF THE RATIONS FOR CHICKS. The cost of food per pound gain in weight for Lot I was-4.1 cents and for Lot II 4.4 cents. For Lot III it was 5.1 cents and for Lot IV 4.5 cents. For the ten weeks with the pullets of the combined lots the cost was 7.7 cents for Lots I and III and 8.3 cents for Lots II and IV. The food cost of the growth made during the first eleven weeks by Lot V was 4.9 cents and of that made by Lot VI was 5.0 cents. The cost of that made during this time by Lot VII was 5.1 cents and of that made by Lot VIII 5.4 cents. When the pullets from the combined lots were fed for four weeks longer the cost of the gain made by the birds from Lots V and VII was 3.9 cents and of that made by Lots VI and VIII 4.3 cents. After adding to these lots some more matured pullets from the earlier lots, the one combined lot of older birds, from I, III, V and VII, made for a month a slow and costly gain while the others, from II, IV, VI and VIII, whose growth had been slower, still made good gains at moderate cost. The food cost of the gain made by Lot IX was 5.5 cents and of that made by Lot X 8.0 cents per pound. Owing to the large proportion of Leghorns among the chicks, heavy average weights were never reached, but average weights of one, two and three pounds were always attained much sooner by the chicks having the animal food ration. The first four lots reached the average weight of one-half pound at about the same 92 Report oF THE DEPARTMENT OF ANIMAL HUSBANDRY OF THE time. Lots V and VII averaged one-half pound in weight over a week sooner than Lots VI and VIII and Lot IX over two weeks sooner than Lot X. The average weight of one pound was reached by Lots I and III about a week sooner than by Lots II and IV, the average weight of 1.5 pounds three and one- half weeks sooner, and the average weight of 2 pounds four and four-fifths weeks sooner. The average weight of one pound was reached by Lots V and VII two weeks sooner than by Lots VI and VIII, the average weight of 1.5 pounds over three weeks sooner, the average weight of 2 pounds three and three-fifths weeks sooner, the average weight of 2.5 pounds over four weeks sooner. The average weight of one pound was reached by Lot IX three weeks sooner than by Lot X, the average weight of 1.5 pounds three and four-fifths weeks sooner and the average weight of 2 pounds three weeks sooner. EXPERIMENT WITH DUCKLINGS. In the experiment with ducklings the birds in the two lots were all Pekins. Lot A had the rations mentioned on page 77 containing animal food and Lot B the ration of vegetable food. These rations were fed unchanged during the first month. It was then evident that the one ration was very deficient in some respect, for before the end of the fourth week one-half of all the birds in Lot B had died. Animal meal was then added to the ration, otherwise unchanged, for three weeks and then for two weeks longer the original ration was fed. Only one bird died after the first change in the ration. None died in Lot A. After the ten weeks Lot B was fed for five weeks on the ration which had been fed to Lot A, and Lot A was also fed the same ration for three weeks longer.

The ration containing the animal meal was more freely eaten. Calculated on the basis of dry matter the food consumed by Lot A during the first four weeks was more than twice as much as that by Lot B and the net gain in weight more than ten times as great. For each pound gain in weight there were 2.6 pounds of dry matter in the food for Lot A and 6 pounds for Lot B. During the following five weeks 40 per ct. more food was con- sumed by Lot A than by Lot B and the gain in weight made by Lot A was more than twice that made by Lot b. The amount of dry matter in the food for each pound gain was 3.6 pounds for Lot A and 4.8 pounds for Lot B. For the nine weeks over 50 per ct. more food was consumed by Lot A and the total net gain in weight was 2.7 times more than that of Lot B. There were 3.3 pounds of dry matter in the food for Lot A for each pound gain in weight and 5 pounds for Lot B. When the birds remaining in Lot B were finally changed to the ration that had been fed to Lot A a rapid growth was made and while the gains were not so good as had been previously made by Lot A they were better than those made at this time by the more nearly mature birds in Lot A during three weeks feeding on the same ration. For the five weeks there were 5.1 pounds of dry matter in the food for Lot B for each pound gain in weight and for the three weeks for Lot A 7.4 pounds for each pound gain in weight. It was therefore apparent that while the vegetable food ration greatly retarded the growth up to ten weeks of age and was the cause of ereat mortality, it did not pre- vent a rapid and profitable growth by the surviving birds under the better ration. The effect of the first few weeks under the inferior ration could not be entirely overcome however, and the birds from Lot B never reached as satisfactory development as did the others. RELATIVE ECONOMY OF THE RATIONS FOR DUCKLINGS. The cost of the food for each pound gain in weight during the first four weeks of the experiment was for Lot A 2.7 cents and 96 Reporr oF THE DEPARTMENT OF ANIMAL HusSBANDRY OF THB for Lot B 10.1 cents. During the next five weeks the cost was 3.7 cents for Lot A and 5.3 cents for Lot B. For the whole time up to ten weeks of age the food cost per pound gain was 3.4 cents for Lot A and 5.9 cents for Lot B. After Lot B was finally changed to the animal food ration the food cost per pound gain for the five weeks was 5.6 cents. The food cost per pound gain in weight made at this time by Lot A for three weeks after they had reached the average weight of five pounds was 7.6 cents. At ten weeks of age the ducklings in Lot A averaged 4.9 pounds in weight and those in Lot B 2 pounds. At seven weeks of age those in Lot A averaged 3 pounds in weight and those in Lot B 1.1 pounds. The ducklings in Lot B at five weeks of age, up to which time they had been restricted to the unmodified veg- etable food ration averaged but 0.4 pound in weight while those in Lot A averaged four times as heavy. Even with the addition of other food to the vegetable food ration, followed later by a total change, the ducklings in Lot A reached the average weight of one pound three weeks sooner than those in Lot B. The av- erage weight of 2 pounds was reached more than three weeks sooner, the average weight of 3 pounds four and one-half weeks sooner, the average weight of 4 pounds and the average weight of 5 pounds each a month sooner. The average weight of 5 pounds was attained by Lot A when Lot B averaged but little over 2 pounds in weight. Besides avoiding the serious loss that occurred under the ra- tion entirely of vegetable food, the chief advantage of the animal food ration was in the much more rapid growth and earlier ma- turity and not so much in the ultimate attainment of greater size. FEEDING EXPERIMENT WITH HENS. Of the four lots of laying hens used in this series of experi- ments, Lots XVII and XVIII were fed the contrasted rations for about seven and one-half months and Lots XIX and XX for about six and one-half months. This included the principal New Yorx AcricutturaL Experiment STatTIon. 97 part of the laying season. Lots XIX and XX were alike at the start, containing equal numbers of two-year-old Wyandotte hens. Lots XVII and XVIII contained equal numbers of Leghorn pul- lets. The pullets in Lot XVII had been fed from the day they were hatched a ration which contained a large proportion of an- imal food, while those in Lot X VIII had been grown on a ration of vegetable food supplemented by some skim milk curd. Some of the pullets in both lots had been laying for some time before this experiment began but those in Lot XVII had commenced laying several weeks younger than those in Lot XVIII. The hens in the other two lots had been treated alike until used in this experiment. Lots XVII and XIX were fed the ration con- taining animal meal described on page 77 and Lots XVIII and XX were fed the contrasted ration.

About 13 per ct. more food was eaten and 31 per ct. more eggs were laid by Lot XVII having the ration containing animal meal than by Lot XVIII. During the thirty-two weeks the average ege production per hen was 110.1 eggs for Lot XVII and 84 eggs for Lot XVIII. Eggs from both lots averaged about the same in weight. The amount of dry matter in the food for each pound of eggs produced was 3.7 pounds for Lot XVII and 4.3 pounds for Lot XVIII. The cost of food for each pound of eggs produced was the same for both lots, 4.1 cents, and the food cost per dozen eggs was 5.9 cents. Lot XIX ate nearly 15 per ct. more food than Lot XX and laid over 36 per ct. more eggs. During the twenty-eight weeks the average egg production per hen was 72.7 for Lot XIX and 53.3 for Lot XX. The eggs from Lot XIX averaged somewhat larger. The amount of dry matter in the food for each pound of eggs produced was 4.3 pounds for Lot XIX and 5.5 pounds for Lot XX. The cost of food for each pound of eggs produced was 4.8 cents for Lot XIX and 5.2 cents for Lot XX. The food cost per dozen eggs was 7.8 cents for Lot XIX and 7.9 cents for Lot XX. With these two lots of older hens which had not been under the effect of similar rations before the experiment began there was no difference in the laying noticeable during the first twelve weeks, but after the cumulative effect of the rations be- gan to be felt the superiority of the one ration for sustained egg production became more evident. A study of the tabulated data will show this. With the two lots of younger birds, which had been since hatching under the influence of somewhat similarily contrasted rations, the difference in egg production was apparent from the start. This difference was even more noticeable after several months although the lot having the animal food had been laying longer under the influence of the preliminary rations before this experiment began. For short periods during part of the laying New York AqricutturaL Experiment Srarion. 103 season the vegetable food ration was used as efficiently as the other, but the subsequent decline in egg production was more rapid than under the other ration. It will be noticed by refer- ring to the tabulated data that the birds in Lot XVII were dur- ing every period somewhat heavier than those in Lot XVIII. This was due to the actual difference in size and not to accum- ulation of fat. This difference between the lots had been much more noticeable before they reached maturity. No particular differences were noticed in regard to broodiness or molting. ORSERVATIONS RELATIVE TO THE EGGS. During the first few months a cockerel was kept with each of the two Lots XIX and XX. These birds were alternated be- tween the two lots so that any difference in the general fertility of the eggs might not be attributable to any difference in male birds. The eggs from Lot XIX showed a somewhat greater per- centage of fertility than those from Lot XX but there was little difference in the vitality of the germs. During about four months one cockerel was kept alternately with Lots XVII and XVIII. Eggs were examined several times during the season both when they were probably at their best and later when they were poor. On the average there was a large percentage of fertile eggs, there were fewer of the very weak germs, and the proportion of chicks hatched from the tested eggs was greater for Lot XVII. Two lots, ten in each, of two year old hens were also fed these contrasted rations for a few months, although full data were not collected. One male bird was kept alternately with the two lots. Eggs from the two lots showed the same percentage of fertility, but there were fewer weak germs in the eggs from the lot having the animal food ration and more chicks were hatched from the tested eggs. Eggs from all the lots were sometimes kept for a long time before use, but contrasted lots were treated alike. Eggs from 104 Report or THE DEPARTMENT OF ANIMAL HUSBANDRY OF THE none of these lots were so good for hatching as eggs from some hens having practically free run, nor as eggs from some other matings of birds kept confined. No general differences were apparent in the average weights attained by the chicks hatched from eggs from the several contrasted lots, nor in the vigor of the chicks while growing. There was some difference generally in the size of the eggs in favor of the lots having the animal food. But little difference in the nutritive value of the eggs was found by chemical analysis. Such differences as were found will be later considered in con- nection with other work. The shells were generally heavier o eggs from those birds having the animal food ration. Twenty tests of the table qualities of the eggs were made by ten different families. Preferences did not all coincide. Eggs from Lots XVII and XVIII were on the average about equally preferred, while a nearly unanimous opinion favored eggs from Lot XIX over those from Lot XX. Opinion seemed to be influenced fa- vorably by the generally darker colored yolks and firmer consis- teney of the eggs from hens having the animal food. When a preference in regard to flavor was expressed it was nearly always in favor of the eggs produced under the vegetable food ration. SECOND SERIES OF EXPERIMENTS. In another series of experiments two lots of chicks were fed for nine weeks and four lots for eleven weeks. Two lots of ducklings were fed for nine weeks and two lots of laying hens for seven months. The contrasted feeding, as in the former experiments, began with the chicks and ducklings when they were one week old and continued until they were ten or twelve weeks old. The same conditions existed in regard to manage- ment and accommodations. RATIONS IN THE SECOND SERIES. One ration for chicks and hens consisted of wheat, corn and a mixture, No. 3, composed of 27 parts by weight of corn meal, NEw York AGRICULTURAL EXPERIMENT STATION. 105 25 parts of animal meal, 5 parts each of wheat bran and malt sprouts, 3 parts each of wheat middlings and Buffalo gluten meal. and 2 parts each of buckwheat middlings and pea meal. The contrasted ration consisted of wheat, corn and a mixture, No. 4, composed of 12 parts of wheat bran, 11 parts of King gluten meal, 9 parts each of malt sprouts, buckwheat middlings and bone ash, 6 parts of O. P. linseed meal, 5 parts of pea meal, 4 parts of corn meal, 3 parts each of brewer’s grains and ground flaxseed, and 2 parts of wheat middlings. To every 360 pounds of each mixture one pound of salt was added. The ducklings had wheat bran and corn meal with each of the contrasted mix- tures. Green alfalfa was fed to every lot. Sand and coarse grit were liberally supplied to the chicks and ducklings and grit and oyster shells to the hens. The valuations assumed for the foods have been mentioned on page 78. The average composition of each food used in these experiments is shown in the following table. Special analyses of the green alfalfa and alfalfa hay were not made but the aver- age of many analyses showing the composition of numerous sam- ples fed in previous experiments were used in the calculation of rations.

The bone ash appeared therefore to partly supply a deficiency which had existed in some other rations, but it did not bring the ration anywhere near to the efficiency of the ration contain- ing animal meal. The contrasted rations were nearly alike in chemical composition so far as the groups of constituents are ordinarily considered in feeding. EXPERIMENT WITH LAYING HENS, SECOND SERIES. The two lots of laying hens which were fed the contrasted rations were Leghorns and had been laying well for two or three months before the experiment began. ‘The two lots were alike at the start. The ration containing animal food was fed to Lot XXI and the vegetable food ration to Lot XXII. The hens were liberally fed but not more than was promptly and readily eaten. Chopped alfalfa hay was fed during the first period and green alfalfa during two others. For about three months the hens were allowed to get their green food from grass runs and the amount eaten was estimated from the amount of green forage eaten at other times when it was freely fed. An interrogation point accompanies the statement of amount of green fodder for the periods when it was estimated. The records of feeding and the results obtained are stated in condensed form in the accom- panying tables. RELATIVE EFFICIENCY AND ECONOMY OF THE RATIONS FOR HENS. The difference in food consumption under the two rations was practically nothing. For the thirty weeks there was only about one-half per ct. difference in the total dry matter of the food. Up to the beginning of the last period the total consumption was exactly the same. The rations were intended to correspond very closely in regard to the proportions of constituents, and this they proved to do, although there were slight differences.

For nearly six months the proportion of dry matter in the food for each pound of eggs produced was 2.8 pounds for Lot XXI and 2.9 pounds for Lot XXII. Al- though the cost of food was somewhat more under the animal food ration, the egg yield was enough larger to make the food cost of eggs about alike for both lots. For the whole time the average cost for each pound of eggs was 3.2 cents for each lot. For all but the last period the average was 3.1 cents for Lot XXI and 3.0 cents for Lot XXII. The average food cost per dozen eggs was, for the thirty weeks, 4.7 cents for Lot X XI and 4.6 cents for Lot XXII. No general difference was noticed in regard to molting. OBSERVATIONS ON THE EGGS. Two cockerels were kept, one with each lot, during the first three and one-half months. The birds were alternated between the two lots so that average and general differences in the eggs would appear justly credited to the hens. The eggs from Lot XXI proved better from the breeders’ standpoint than those from Lot XXII. Eggs from both lots were sometimes kept several weeks. Five hundred eggs from each lot were examined and in- cubated. Eighty-six per ct. of those from Lot XXI were fertile, 19 per ct. of the fertile eggs had very weak germs and 77 per ct. of the tested eggs hatched strong chicks. Of those from Lot XXTI, 78 per ct. were fertile, 34 per ct. of the fertile eggs had New Yorx AaricuLtturRAL ExprrimMent Station. 121 very weak germs and 64 per ct. of the tested eggs hatched strong chicks. arly in the season some of the eggs from both lots were much better than these average results show and later some were much inferior. The cockerels used were undoubtedly responsible for many fluctuations in fertility of the eggs, for there were pro- nounced differences consistently following changes of the male birds. A circumstance was noticed in the later hatches which seems worthy of record for it suggests a difference in the prepotency of the hens in the two lots. The hens used were thoroughbred S. Combed W. Leghorns and the cockerels were pure W. Wyandottes. From Lot XXI almost exactly one-half of the number of chicks hatched (52 per ct.) had the single comb characteristic of the female parent, while all the chicks from Lot XXII had the rose comb characteristic of the male parent. Unfortunately these ob- servations were limited and apply only to about eighty chicks of the later hatches as the opportunity was lost for observing the chicks of the earlier hatches. No difference in the vigor of the chicks from the two lots while growing was observed. SUMMARIZED DATA. With every lot of chicks in the first series (Lots I, IV, VI, VIII and X) having a ration wholly of vegetable origin more food was required to produce a pound gain than by the contrasted lot (Lots I, III, V, VII, TX). On the average for the ten lots about 23 per ct. more food was required. The two lots of laying hens, XVIII and XX, required on the average about 23 per ct. more food for each pound of eggs pro- duced than did Lots XVII and XIX having animal food. Lot B of ducklings required about 2.3 times as much food for each pound gain in weight as did Lot A having the unchanged ration containing animal food. Every lot of chicks in the second series (Lots XI, XIII and XV) having a ration containing animal food required more food 122 Reporr or true DEPARTMENT OF ANIMAL HUSBANDRY OF THE for each pound gain than did the contrasted lot (Lots XII, XIV and XVI) having vegetable food supplemented by bone ash. On the average about 13 per ct. more food was required. Less than 7 per ct. more food was required by Lot XXII of laying hens for each pound of eggs produced than was required by Lot XXI. Lot D of ducklings required over 30 per ct. more food for each pound of gain in weight than did Lot C having animal food. GENERAL CONCLUSIONS. In some feeding experiments conclusive results can be obtained in a direct manner from a few animals. In other feeding experi- fents, however, where mixed foods must necessarily be used longer than for a short time, many conditions exist which cannot be subjected to particular control, and the nature of the evidence is so largely circumstantial that conclusions can only be satisfactory when they are based upon data from several feeding trials and a larger number of animals. In these experiments relating to the use of animal food, including the preliminary trials reported in Bulletin 149, 1,000 chicks and 170 ducklings were grown to mar- ketable size; 90 hens and 40 cockerels were used. The results, therefore, not any of which are of conflicting nature, seem to justify certain conclusions. In general, rations containing animal food appear more palat- able than rations of somewhat similar chemical composition con- sisting wholly of vegetable food. ations in which the lack of palatability was overcome by using an unusual variety of grain foods were inferior for growing chicks and laying hens and de- cidedly inferior for ducklings to rations in which nearly one-fifth of the dry matter was supplied by animal food. After the period of most rapid growth had passed and the young birds approached maturity the difference in the efficiency between such rations rap- idly disappeared. New Yorx AGrRIcuULTURAL EXPERIMENT SraTIon. 123 Although it was found possible, when using a large number of foods in contrasted rations of these kinds, to have the ordinary groups of organic compounds in approximately equal proportions there was always a much larger amount of mineral matter in the one ration owing to the bone of the animal meal. So there was sometimes nearly three times as much phosphorous in the one ra- tion as in the other. Calculating all the phosphorous as phos- phoric acid, there was in the animal meal ration fed to chicks and . hens generally about 3.9 per ct. of phosphoric acid, while in the ration of vegetable origin there was about 1.4 per ct. In the con- trasted rations for ducklings there were 4.0 per ct. and 1.9 per ct. of phosphoric acid, respectively. By using bone ash in another series of experiments, the amount of phosphorus was made to equal and sometimes slightly exceed that in the animal food ration, although all the organic matter was still derived from vegetable food. There was in the animal food ration fed to chicks, phosphorus equivalent to about 3.9 per et. of phosphoric acid and in the contrasted ration to about 4.0 per ct. The animal food ration for ducklings contained about 3.6 of phosphoric acid and the vegetable food ration about 4.0 per ct. Both rations for laying hens contained about 3.6 per ct. of phosphoric acid. Practically the same relative amounts of protein, fats and carbohydrates existed in the contrasted rations. The vegetable food ration, thus supplemented by the mineral mat- ter of bone ash, when fed to chicks, proved fully equal to the ration containing animal meal, so far as rapidity of growth was concerned. In economy it was even somewhat superior, for con- siderable less food was required for equal results. For laying hens the rations were equal in efficiency for some months, but the ration containing animal food proved somewhat more enduring in its effects. With ducklings the ash-supplemented ration of vegetable food proved decidedly inferior to the corresponding ration con- taining animal food. From these results it appears that rations containing a neces- sary amount of protein and having the relation of the ordinarily 124 Revorr or ror Department or ANIMAL HUSBANDRY. considered constituents satisfactory may be inferior because of a lack of mineral matter, probably phosphates. Not enough data are now available to show to just what ex- tent the deficiency of lime in the food for the younger chicks may have been responsible for inferior results. With laying hens, lack of lime could not have affected the results considered; for oyster shells were freely supplied, and it has been shown (see Bulletin No. 38) that such material can make good the frequent deficiency of lime. It appears also that, while a cheaper vegetable food ration can sometimes be made to equal or surpass in efficiency a ration con- taining animal food by supplementing it with suitable mineral matter, there are plain limitations to its economical use. For lay- ing hens some animal food appears necessary for continued good results. Ducklings without an abundant supply of animal protein in the ration, together with a liberal proportion of mineral matter, seem unable to make any approximation to their normally rapid and most profitable growth. Although bone ash was used to make good an assumed defi- ciency in one ration and proved an efficient addition for the pur- pose, it should not be inferred that its purchase for feeding is to be generally recommended. It was necessarily used to obtain in- formation. Bone ash in the market is expensive. The same amount of mineral matter can be obtained much cheaper in fresh bone or animal meal, of which foods it constitutes an important part. In some instances, of course, dry bones, where no facili- ties exist for grinding, or green bones in questionable condition, can be safely and economically used when charred or reduced to ash. The very desirable organic matter associated with fresh or cooked bones should not be wasted. REPORT OF THE Department of Bacteriology H. A. Harpine, Bacteriologist. L. A. Rogers, Student Assistant.

THE EFFICIENCY OF A CONTINUOUS PAS- TEURIZER AT DIFFERENT TEMPERA- TU RES.* H. A. Harpine anp L. A. Rogers. SUMMARY. These tests were made by passing mixed whole milk through a Danish continuous pasteurizer. At 70°C. (158°F.) the efficiency of the continuous pasteurizer varies greatly from day to day. Tests upon 14 different days gave an average of 15,288 living germs per cubic centimeter left in the pasteurized milk, with a maximum of 62,790 and a minimum of 120 germs. At 80° C. (176° F.) the reduction in germ content is both very uniform and very great. Tests upon 25 different days gave an average of only 117 living germs per cubic centimeter in the pasteurized milk, with a maximum of 297 and a minimum of 20 germs. At 85° ©. (185° F.) the average reduction is not more marked than at 80° C. but the range of variation is less. This temperature has the added advantage, according to Dr. Bang, of removing the danger from germs of tuberculosis in the milk. Even when the whole milk was heated to 85°C. the butter did not have a permanent cooked flavor. INTRODUCTION. An inquiry into the laws which underlie any of the complex commercial processes will progress slowly if each step is deter- * Reprint of Bulletin No. 172. 128 REPORT OF THE BACTERIOLOGIST OF THE mined with a thoroughness that allows of safe generalization from the data obtained. In order that the reader may see the relation of this piece of work to the problem that is being studied, let the following facts be borne in mind. THE DANISH SITUATION. Dairying is one of the principal industries of Denmark and during the past two decades the government has fostered it both by the equipment of experts to study its problems and by pro- tective legislation. In 1890 Dr. Storch announced that, by changing the kind of bacteria that grow in ripening cream, he was able to change the flavor of the butter. Dr. Bang, after studying the conditions under which tubereu- losis was distributed among cattle, perfected a system of separating the diseased animals from the healthy ones and gradually replac- ing the former. In carrying out his plan, the feeding of calves upon the skim milk brought from the creamery was found to be a source of danger, but this could be removed by heating the milk momentarily to 85°C. (185°F.). As the result of these and other investigations, there has spread over Denmark a peculiar method of making butter —a method so successful that, to-day, Danish butter is a standard of excellence wherever it is known. Cleanliness in all details and an intelligent appreciation of the relation of bacteria to butter-making are widespread, but the key- note of their system is preparation of the starter itself and the cream to receive the starter. By a starter they rarely mean the mixture of bacteria, desirable and undesirable, which commonly receives that title in New York. They mean a mixture of known kinds, each of which has been found desirable in itself. This united action of several species gives a better flavor to the butter than could be obtained from any single species. a New York AaricuLTuRAL ExprerRIMENT Station. 129 This mixture of germs, when received from a laboratory, is introduced into milk that has been first heated to near the boiling point for 2 hours to kill other bacteria and then cooled below blood heat. This starter is propagated from day to day with so much care that at the end of four to six weeks, when it is finally rejected for a new one, the usual fault with it is merely a too sharp flavor of acid. The preparation of the cream begins with cleanliness in the barn. Either the whole milk or the cream after separation is heated to free it of objectionable forms before receiving the starter. This heating is only momentary and various temperatures are advocated — those from 70° C. (158° F.) to 95° C. (203° F.) having been used. After heating, the cream is quickly and thor- oughly cooled. Formerly cream was heated after separation, both for economy and because of less opportunity for after-contami- nation. , A knowledge of the inercase in feeding value produced by pro- longing the period of sweetness, and, later, a desire to prevent the spread of tuberculosis among their calves, caused the skim milk to be heated above 85° ©. (185° F.). Since it has been found that the capacity of the separator is increased by skimming at high temperatures and that whole milk can be heated to 90° C. (194° F.) without injury to the flavor of the butter, there is a tendency toward a single heating of the whole milk. The points of excellence claimed for the Danish product are uniformly good quality and the property of holding its flavor for long periods. TIIE AMERICAN SITUATION. Butter is now selling at from 14 to 28 cents per pound, with less than 15 per ct. of the product bringing the latter price. The quality of the best butter is above reproach, but the lamentable thing is the lack of quantity of such butter. So great is this lack 9 130 Report oF THE BACTERIOLOGIST OF THE that during at least a portion of the year it is impossible to buy first-class butter in many of the moderate-sized cities in this, the greatest dairy State in the Union. These facts show that there is abundant room for improvement, and anything that will raise the average quality of the product will be gladly welcomed, both by the dairyman and the consumer. After the Danish success became an established fact, Ameri- cans attempted to copy their methods, but thus far the results” have not been up to their expectations. Tests carried on by the Agricultural Experiment Stations of Wisconsin and Pennsylvania, as well as by the Department of Agriculture at Washington, failed to show that there is any financial gain to be derived from the process when practiced as usually recommended. Believing that the above failures are due to some of the modi- fications that the system has undergone in being brought from Denmark to America, this Station has undertaken to follow the process step by step, hoping to find the proper American condi- tions under which we can not only make a more uniform product, but one that will be sufficiently improved to justify the additional expense in preparation. The solution of this problem calls for the co-operation of a number of the departments of the Station and will require con- siderable time; hence, it is proposed to issue the results in a series of bulletins, of which this is the first. While the Bacteriological Department assumes the responsibility for the statements contained in this bulletin, much credit is due our Dairy Expert, Mr. Geo. A. Smith, whose wide experience in dairy matters has materially con- tributed to the success of the practical side of the work. WHAT IS MEANT BY PASTEURIZATION. As long ago as 1782, a Swedish chemist, Scheele, found that ~ after immersing bottles of vinegar in boiling water for a-time, the 1 Hansen, Emil. Chr. Practical Studies in Fermentation, p. 158. Nzw Yorx AGRICULTURAL EXPERIMENT STATION. 131 vinegar would not become turbid or spoiled as long as it was kept carefully closed. Early in the nineteenth century Appert” applied this idea of heating inclosed fluids to prevent fermentative changes to the preservation of fruits, vegetables, soups, milk, fruit juices, wine and beer. : A half century later Pasteur turned this knowledge of the effect of heat in delaying fermentation to practical account in combating scme of the undesirable fermentations of wine and beer, with such success that the process has been called pasteuriza- tion in his honor. Our present methods of canning fruit and vegetables are probably the result of the early discoveries. The application of heat in this way had become such a household matter by the time the process received this special title that the name was not carried over to the ordinary househould heating would to-day be quite and a ean labeled “ Pasteurized Peaches ” a puzzle, although from its manner of preparation it can justly claim that title. Pasteurization, then, is simply the application of heat to check the activity of fermentation. The temperature used depends upon the substance treated and the end to be attained. The effect upon germ life will vary both with the degree of heat and the length of exposure. The same results can be secured in the killing of Bacillus tuberculosis when the milk is heated at 60° C. (140° F.) for 30 minutes or at 85° C. (185° BF.) for a very short time. PASTEURIZATION CONFUSED WITH STERILIZATION. Sterilization is a good word that has been debased by popular usage. In its true sense it means the total destruction of life. It is often used to mean anything from a simple warming to a thorough boiling. Such words are best used in their true sense 2 Loc. cit., p. 159. 132 Report or THE BAcTERIOLOGIST OF THE or not used at all. It should be remembered that some of the organisms which are often found in milk will successfully with- stand boiling for some hours and the sterilization, in the true sense, of any commercial quantity of milk at a single heating is a practical impossibility unless temperatures above that of boil- ing water are used. THE TWOFOLD APPLICATION OF PASTEURIZATION TO MILK. The subject of the pasteurization of milk has been presented to the American public with reference to two distinct problems — the sanitary milk supply of cities and the production of uni- formly good butter. While heat is applied in both cases the methods of application which have been found most successful in each are radically different and an attempt to accomplish either object by the other process has not yet been shown to be practical. The first method is too slow and expensive to be adapted to butter making and the second plan when carried on at a temperature sufficiently high to kill the tubercle bacillus gives an objectionable flavor to the milk. Fortunately this flavor does not remain in the butter. THE DISCONTINUOUS OR HOUSEHOLD SYSTEM. About ten years ago when the use of tuberculin was bringing home the alarming prevalence of tuberculosis among our dairy cows and the danger of transmission of the disease to invalids and children through milk seemed self-evident, pasteurization was brought forward as a safeguard from this danger. In this method the milk was heated at a definite temperature for a defi- nite length of time. At first 67.3°C. (155°F.) for 20 minutes was advocated, but owing to the change brought about in the viscosity of the milk and New York AGRICULTURAL EXPERIMENT StTaTIon. 133 cream by exposure to this temperature, heating to 60°C. (140°F.) for 30 minutes is now coming more into favor. According to the researches of Dr. Theobald Smith,? 15-20 minutes at 60°C. (140°F.) is sufficient to kill the tubercle bacillus provided the milk is kept stirred so as to prevent the formation of a pellicle at the surface. Higher temperatures and a shorter time would give the same result, but when the temperature of 70°C. (158°F.) is passed the milk takes on a disagreeable, cooked taste. This is largely due to an oxidation of some of the components of the hot milk and it is possible that in the future a way may be found of avoiding this flavor. | The main feature in the discontinuous process is the removal of the danger from disease and. this applies not only to tubercu- losis but to all other germ troubles which are liable to gain access to the milk before it is heated. The keeping quality of the milk is much improved, especially if proper attention is given to keep- ing it cool after treatment and the effect of the carelessness and lack of cleanliness which are often prevalent at the barn is in a measure removed. A very commendable practice exists of pass- ing the milk through a separator and remixing the milk and cream before pasteurization. This removes a large part of the hair, excrement, etc., which is so common in the ordinary milk supply of cities. This method of handling milk for immediate consumption is in successful operation in a number of cities on a large scale. It has much to commend it and when done in a large way it does not increase the cost of production more than a small fraction of a cent a quart. THE CONTINUOUS OR DANISH SYSTEM. When the Danish system of butter making was introduced into America pasteurization came as a necessary part of it, but in this case the principal object was the fitting of the cream to receive 3 Journal of Experimental Medicine, 4: 217-233 (1899). 134 Report oF THE BACTERIOLOGIST OF THE the starter of selected bacteria so that the desired flavor might be always obtained. The problem that presents itself is not different from that which confronts every farmer who attempts to grow a field of oats. If he sows his seed upon land already filled with rapidly growin clover, Canada thistles and ragweed his chances of a good oat crop are poor. If he first fits his land and kills off the other plants the oats will have a better chance. To make a success of this it is not necessary to kill off every weed in the field for if the oats are much in the majority and get the start of the others they will control the situation and suppress the weeds. The bacteria are plants of more simple form than those in the above illustration, but they obey the same laws of competition in growth. If conditions are so arranged that the starter when added to the cream finds the same filled with rapidly growing enemies, the effect of the starter will be largely or wholly lost; while if it is added to cream from which all or nearly all of its competitors have been removed, the starter will assume control of the situation and suppress its enemies. In the Danish machine the milk is introduced at one end of a cylinder surrounded by steam and flows continuously from the other end having been momentarily heated to the temperature desired. The temperatures used have had an upward tendency and sine Dr. Bang announced that when working with tuberculous cows furnishing the diseased germs in their milk the milk was ren- dered harmless when passed through one of these machines - 85° C. (185° F.), this has been taken as the Danish minimum legal temperature for heating all the by-products that are to be returned to the farm for feeding purposes. In a country where the most determined effort is being made to stop the spread of tuberculosis among cattle the value of this protection to a dairyman who has succeeded in freeing his own - herd from the contagion, but yet is compelled to raise his calves New York AGRICULTURAL EXPERIMENT STATION. 135 upon mixed milk brought from the creamery, should not be over- looked. In this as in their other acts regarding the suppression of tuber- culosis the Danes have shown a laudable moderation and consid- eration of the rights of all concerned. The legal enactment as to the temperature to be used was not made until the pasteurizing process had been voluntarily adopted and the necessary machinery installed in practically every creamery in the country. The American promoters of the Danish method, knowing from their previous experiences with the other form of pasteurization that a heating above 70° C. (158° F.) produces a disagreeable flavor in the milk, were either not willing to trust the practical experience of the Danes or hopelessly confused the two problems and recommended 67.3° C. (155° F.) to the American experi- menters when the Danish practice is to employ a temperature at least 12.7° C. (25° F.) higher. The points in which their reasoning went astray were two: First, the cooked taste in milk, at least for the most part, is not a matter of absolute temperature at which the milk is heated, but rather the result of an exposure of hot milk to oxygen. Milk that has been highly heated in a Danish pasteurizer and imme- diately and thoroughly cooled as is their practice has surpris- ingly little of the cooked taste. Second, the cooked flavor does not attach itself tenaciously to the fat of which the butter is almost exclusively prepared and butter made from highly heated milk that may have a slightly cooked taste immeditely after churning losses this objectionable flavor in a very short time. Believing that a failure to properly heat the milk might be a factor in the lack of success of past American experiments our investigations began with this point. THE PROBLEM STUDIED. The objective point was to determine the effect upon the germ- life when milk was passed through a continuous pasteurizer at 136 Report oF THE BAcTERIOLOGIST OF THE different temperatures. So far as data were at hand this had been done but twice in America. Both of these tests had been carried out at about 70° C. (158° F.) and the trials were too few in number and the results too contradictory to form a safe basis for generalization. At the Wisconsin Station* it was found that, while there was considerable variation in the effect of a heating of 67.3°-74° C. (155°-165° F.), in some cases as many as 40 per ct. of the bacteria survived and in the tests published this number remain- ing amounted to over 2,000,000 germs per cubic centimeter. A different kind of continuous machine was used at the Penn- sylvania Station® and no numerical results were given, but it was stated that “ Heating to this temperature 67.3°-70° C. (155°- | 158° F.), for this length of time, as was found by culture plates, destroyed few, if any, of the bacteria present in the milk.” Since 70° C. (158° F.) is the lowest temperature which is gen- erally recommended for continuous pasteurizing this was taken as a starting point in our work and when the effect of this tem- perature had been observed higher degrees were used. MACHINE USED. We are indebted to D. H. Burrell & Co., Little Falls, N. Y., for the loan of a continuous pasteurizer made by Konstantin Hansen & Schroder, Kolding, Denmark. This has a rated capac- ity of 2,500 pounds of milk per hour heated to 70° C. (158° F.) The accompanying drawing of a cross section (Plate IT) ex- plains the essential parts of the machine. The milk enters at the bottom into a central milk chamber. Here it is set in motion by the stirrer revolving 300 times per minute, which spreads the milk out in a thin layer against the wall and finally expels it at the tangential milk outlet above. This outlet has a lateral open- 4 Pasteurization as Applied to Butter Making, Wis. Agr. Exp. Sta. Bul. 69. 5 Heated Milk for Butter Making, Penn. Agr. Exp. Sta. Bul. 45.

New York AGRICULTURAL EXPERIMENT STATION. 137 ing for receiving the thermometer. As the milk is spread out in this thin layer it quickly takes up the heat from the steam chamber surrounding it. The temperature of the milk is controlled by changing either the valve admitting the steam or the valve regulating the milk flow. A slight change in either of these valves produces a quick response in the mercury column of the thermometer. Usually the milk valve was set to admit about all the milk that could be heated to the desired degree and the slight variations in tempera- ture were controlled by changing the steam valve. METHOD OF WORK. In the manipulation of the machine at the different tempera- tures the effort was always made to give it a fair chance to show what could be expected of it when handled in the average cream- ery at that temperature. Our ability to give it a fair trial in- creased as we became familiar with the machine and its manipula- tion. The first requisite was a method of regulating the flow of milk and steam so that the temperature might be held constant. When received, the machine was provided with a float intended to con- trol the flow of milk automatically. After testing it in a variety of ways for some weeks it was condemned as too clumsy for our purpose and was removed. As finally arranged a supply tank placed sufficiently high to give a good fall was connected directly with the base of the pasteurizer and the flow regulated by a hand valve. This brought the milk and the steam valves near together where one man could reach both and still watch the thermometer. The maxi- mum variation, which rarely exceeded 10° C., usually occurred at the beginning of the process before the valves were properly adjusted. This having been accomplished the desired tempera- ture could be maintained with very little variation. 138 Report or THE BAcTERIOLOGIST OF THE In order to make the control of the temperature as well as the collection of the desired data more accurate the milk was thor- oughly mixed in a tempering vat before starting the machine. The arrangement of the apparatus will be better understood by referring to Plate III. DATA COLLECTED. In the Dairy the interest centered upon the temperature used and in the Laboratory upon the numerical content of germs in the milk before and after heating. A large amount of data was collected in both places bearing upon a number of points. Notes were taken upon the age, weight, initial temperature and acidity of the milk, the steam pressure in the boiler, the rate of the pasteurization and the maximum, minimum and _ pasteurizing temperature employed. Age.— With age there is an increased growth of bacteria and a larger number of spores present. This is what makes the suc- cessful pasteurization of milk over 24 hours old so difficult. During a large part of the time the mixted milk was made up of portions 4, 12, 24 and 36 hours old. Weight.— This varied considerably but averaged 350 lbs. As the machine while in operation contained only about five pounds of milk and all that was really necessary was to hold the tempera- ture at the desired point at the time of taking the sample this was quite enough for our purpose. * Initial temperature.— The termperature of the mixed milk was noted in the tempering vat. For the most part our milk was brought to about 26° C. (78.8° F.) as being a high average tem- perature for summer conditions. As received ordinarily in cream- eries in this State milk varies from near the freezing point in winter to 35° C. (95° F.) in rare cases in summer. The temperature of the milk as it enters the pasteurizer exerts an influence upon the amount that the machine can heat to a desired degree. | ! | f 2: Ree Sa eLPRIT mi a i! ince Jd Ean NI mr ‘ly nT i id “rina | UTC) } TT PLATE III.—ARRANGEMENT OF MILK RECEIVER AND PASTEURIZER. Bae < - aah =i New Yorx AGRICULTURAL ExprERIMENT StTaTIon. 1389 Acidity As the result of experience in the pasteurization of milk by the discontinuous method it has been found impractical to attempt to pasteurize milk intended for immediate consump- tion when the acidity is over 0.2 per ct. calculated as lactic acid. During a considerable portion of the time our mixed milk has had an acidity above this figure. The custom of expressing acidity in milk by percentages of lactic acid has little to recommend it other than that it is com- mon practice. It is a well-known fact that a part of the reaction called acidity is due to the union of the alkali with the casein and that lactic acid is only one of a number of acids found in milk. The fact always determined is the neutralization as indicated by phenolphthalien of a certain amount of normal solution of alkali. In our results this observed fact is expressed by the num- ber of cubic centimeters of normal alkali neutralized by a litre of milk (n/t). For convenience of comparison the per ct. of lactic acid erroneously assumed from this data is given in paren- thesis. The acidity of our mixed milk ranged from 18.9 n/t (0.17 per ct.) to 40 n/t (0.36 per ct.) and during a considerable portion of the time it was above 22.2 n/t (0.2 per ct.). Thus the conditions of acidity under which the pasteurizing was done were not what would be considered ideal, but rather those which would be found in an average creamery. As the acidity of the mixed milk ap- proached 40 n/t (0.36 per ct.) a considerable layer burned fast to the sides of the milk chamber in the pasteurizer and the accu- mulation in the separator bowl was increased. On Feb. 7 the milk with an acidity of 35.5 n/t (0.32 per ct.) was pasteurized at 85° ©. (185° F.) very successfully; but the next attempt with whole milk having an acidity of 40 n/t (0.36 per ct.) quickly accumulated a layer on the walls of the pasteur- izer and clogged the separator bowl after passing only about 80 pounds of milk. 140 Rerort oF THE BacTERIOLOGIST OF THE Steam pressure.— The pasteurizer was connected by a #-inch pipe directly to the high-pressure steam pipe. As will be noticed in the diagram Plate II, the steam had a free outlet at a point nearly opposite to the inlet, so that there was at no time any ap- preciable pressure on the pasteurizer itself. On the contrary, the steam was nearly all condensed and there was rarely any waste, even when the steam valve was opened to its full capacity. The steam pressure given in the tables is that in the 30 horse power boiler and was noted as one of the possible factors in the great variation in rate of operation on different days. Rate.— The amount of milk which a pasteurizer will heat to a given temperature in a given time is important from the practical standpoint. In order to minimize the variation in temperature to which the milk was exposed and to determine the rate more accurately, it was our custom to add water to the supply tank and when every- thing was running at full speed and the last of the water was leay- ing the tank to add the milk and note the time. After all of the milk had been added and just as the last was leaving the tank the time was again noted. The interval was taken as the time required to handle the milk. Since the amount of milk at any one time between the milk valve and the milk outlet was only about 5 pounds, the error was not great. As one would expect, the rate varies with the pasteurizing tem- perature. The machine was expected to handle 2,500 pounds an hour at 70° C. (158° F.), and would do even more under favorable conditions. In our experience, it did not much exceed 2,100 at 80° C. (176° F.), and handled less at 85° C. (185° F.). It will be noticed that the rate at 80° C. ranged from as low as 900 to a little over 2,100 pounds per hour. This extreme variation is due to a number of factors, among which are variations in steam pressure and initial temperature and the cooking of the milk on to the walls of the pasteurizer. This layer of cooked material not New York AGRICULTURAL EXPERIMENT Station. 141 only acted as an insulator between the milk and the source of heat, but also encroached upon the interval between the revolving stirrer paddles and the wall, forming a rough surface along which the milk must pass. The fact that the machine was not permanently placed and lacked in rigidity was also a contributing factor to the above variations. Pasteurizing temperature.— As soon as the milk enters the bot- tom of the machine it takes up heat from the steam jacket and its temperature rises to the highest point just as it reaches the milk outlet. The temperature at this point is measured by a thermometer inserted in the outlet and constitutes the so-called “ Pasteurizing Temperature,” although the milk really attained this degree only momentarily. As soon as the milk passes from the machine the temperature falls with a rapidity depending upon the surroundings. TAKING SAMPLES. The samples of unpasteurized milk were taken from the tem- pering vat after the milk had been thoroughly mixed. The only exception to this was during the earlier part of the work, when they were taken from the supply tank just before taking the samples of pasteurized milk from the machine. The samples of pasteurized milk were taken from the milk outlet after sufficient had passed to remove the effect of the bac- teria contained in the water used in starting the machine and in the machine itself. Care was taken to secure samples while the machine was running steadily at the desired temperature. The samples of about 15 cubie centimeters each in sterile flasks were set into a room at 1.5° to 4.5° C. (35°-40° F.) until the pasteurization was ended, when they were taken to the labora- tory on the floor above and the quantitative analyses made. BACTERIOLOGICAL TESTS. Method of dilution.— One c. ¢. of the unheated milk was added to 9 c. ¢. of sterile water and the two thoroughly mixed. This 142 Report or THE BAcTERIOLOGIST OF THE process was repeated and a small fraction of a c. ce. from the second dilution was added to the culture medium. Cultures were made in Petri dishes having an internal diameter of 91-92 mm. For the sake of convenience in counting and to prevent the inhibiting effect of closely-crowded colonies, the aim was to so arrange the dilution that the growth would be about 500 colonies to the plate. In the case of the pasteurized milk, no dilution was necessary, but a measured fraction of a cubic centimeter was added directly to the nutrient media. ' Media used.— The tabulated results given below were all obtained upon lactose agar made neutral to phenolphthalein with sodium hydroxide and containing 2 per et. lactose and 1.7 per et. agar. Agar was chosen in preference to gelatin, because in some previous work of a similar nature at the Wisconsin Station it was found that agar at 28° C. (81.5° F.) gave higher numerical results than gelatin at room temperature. Among the substances now available, there seems to be none that will call out all the individual germs when left at any one temperature. It is not maintained by the authors that the numbers given below represent the exact number of organisms present either in the pasteurized or unpasteurized milk. All that is hoped for is that they are a close approximation and that having been taken under similar conditions may be found to be directly comparable. Incubating temperature.— The plates were placed in an incuba- tor at 80° C. (83° F.) and counted at the end of 48 hours. This temperature was believed to be near the optimum for the growth of most of the germs present and the time was thought to give maximum returns with a minimum amount of error. An expos- ure at higher temperature caused a rapid drying of the plates and one for a longer time did not usually give higher results, while the rapid spreading of superficial colonies made the counting un- certain. Growth at room temperature required so much longer time as to complicate the work and the rapid multiplication of certain proteus forms made an accurate count very difficult. New Yorx AcricutturaL Experiment Station. 143 When plates that had been kept 48 hours at 30° CO. were left 3-5 days at 21° C. (70° F.) there was a small average increase on the second count. This indicates that some of the organisms present in the milk did not thrive at the higher temperature. The above results obtained from tests upon 14 days at 70° C. (158° EF.) illustrate the uncertainty of the pasteurizing action at that temperature and in this particular quite agree with the re- sults on 1) previous days when preliminary trials were being made. They also show what misleading conclusions might be drawn when generalizations are made after one or two observations. It should be remembered that in any heating of the milk the most desirable class of acid formers will be among the first to be killed and the residue is composed of germs not likely to improve the flavor of the butter. Just how many of this class of bacteria may be left in the milk without impairing the quality of the prod- uct, like the problem of how many weeds can be left in the field without detriment to the crop, is not clearly understood and a conservative disposition would favor their reduction to the lowest practical limits. A most important fact shown is that 70° C. (158° F.) lies near the lower limit of the killing effect of heat applied in this way. When operating a pasteurizer in a practical way, temporary re- ductions of temperature are almost certain to occur, and if this reduction goes much below 70° C. the killing effect upon bacteria will be very slight. The results of pasteurizing at 80° C. (176° F.) show a surpris- ing reduction in the germ life and this reduction was accomplished with very slight variation on each of the 25 days tested. These 25 tests gave an average of only 117, with a maximum of 297 and a minimum of 20 living germs per c. ¢. in the pasteurized milk. } Comparing this average of 25 determinations made after con- tinuous pasteurization with 6,140, the average number of germs Report oF THE BacTERIOLOGIST OF THE 144 183 960°T 9€6'ST 818°91 0061 : OOF'8E 000°Gzr‘S 083 Or 8c-1 FOS IZ BIE 816 6g PLZT =66F 93-1 9148'S SLE ob-1 966°SLT 8&3 va 9699I E8éI Gl OOT'LT SIL Fe-1 000°98 00s'6T 009°LS 00 6T CGS 000‘3sr'S O0€ -I E66 Sh-S9 E-Ten oe ae O8Ps-l= Obele. = ** a? a: fein eis a8 OSGisi= ‘8OSca. as ag => els a8 am (9) se eee “.

L. Russell’ in 50 samples of milk pasteurized by the discontinuous method for direct consumption, the surprising thoroughness of this continuous pasteurization at 80° C. will be understood. Were it not for the fact that in the present state of our knowl- edge it is believed that a heating of milk to 85° C. (185° F.) na continuous pasteurizer is necessary to remove all danger of tuber- culosis, the use of 80° C. in pasteurization for butter-making, at least in this special machine, would leave little to be desired. Confining our attention to the number of germs found in the pasteurized milk, the results of the above tests show that there is practically no increase in efficiency in passing from 80° C. to 85° C. If we can be allowed to generalize on so narrow a basis as seven determinations the gain comes in an increased regularity in the reduction of the number of germs present. ‘There is also a practical advantage in working at a temperature well above that at which an active germ-killing effect begins. The strongest argument in favor of 85° C. (185° F.) lies in the fact that it is the lowest one that we can use and feel assured that we have removed the danger of returning germs of tuberculosis along with the mixed skim milk from the factory. Leaving out of account all relation of this disease to the human family, its effect upon our calves and pigs is one that we cannot afford to ignore. While it does not come within the province of this bulletin to discuss the effect of heating upon the butter, it will not be out of place to state that, even with cream from milk which had been heated to 85° C., butter was made in which no cooked flavor could be detected when coming from the churn. While our efforts were not universally so successful, still, in the cases where such a flavor was noticeable at churning, this disappeared after a few hours standing. The experience of this Station, so far as it goes, is quite in accord with that of Dr. Storch, who states that whole milk can be heated to 90° C. without any permanent injury to the flavor of the butter. 6 Ann.

SUMMARY. In central New York the foliage of sugar beets, cherries, Nor- way maples and sugar maples has been scorched by excessive transpiration. On Long Island cauliflower has been similarly af- fected. Plants standing in dry, sandy soil have suffered most. With the sugar beet, the leaves blacken and die. In severe cases the plant is killed outright, but generally the affected plants revive and make a second growth. The affected roots are small, frequently discolored, and poor in sugar. With the cherry, part of the foliage, often as much as three- fourths, becomes brown and dead. ‘The variety Montmorency Ordinaire is the one most commonly affected. This trouble has been common in the vicinity of Geneva the present season and is said to have occurred in one orchard quite severely in 1898, with- out, however, affecting the crop of 1899. With the cauliflower, the tips of young leaves turn brown, as if frosted. This occurred quite commonly in eastern Long Island during August, but did little damage. The foliage of Norway and sugar maples is much subject to injury from excessive transpiration. The leaves become light brown or reddish brown. Nursery trees and those recently trans- planted suffer most, but large shade trees are not exempt. Little permanent injury is done except to newly-set trees. * Reprint of Bulletin No. 162. 154 ReEportT oF THE BOTANIST OF THE With all of these plants the trouble is not due to a gradual drying, but to a sudden scorching by the transpiration of more water from the leaves than the roots are able to supply. INTRODUCTION. It is not an uncommon thing for the foliage of various plants to be injured by excessive transpiration. Such injury may be brought about in either of two ways: (1) By a process of gradual drying, such as occurs in plants suffering from drought, and (2) By sudden scorching, as when a fire is built under a tree. With the first kind of injury every one is familiar and those living in the arid and semi-arid portions of our country have frequently observed the latter kind. In Kansas, for example, dry, hot south- west winds often ruin promising crops of corn in two or three days. But here in the East, the sudden scorching of foliage by hot wind and sun is of such rare occurrence that it attracts attention and is generally misunderstood by farmers and fruit growers. It is frequently mistaken for infectious disease. The object of this bulletin is to place upon record some observations on the sudden scorching of the foliage of sugar beet, cherry, cauliflower and maple, due to excessive transpiration. LEAF SCORCH OF SUGAR BEET. About the middle of August, 1899, some farmers in Yates and Ontario counties wrote to the Station that their sugar beets were blighting. On August 29, the writer visited several of the af-— fected fields and found the so-called blight to be characterized as follows: On slightly affected plants the only indication of dis- ease was to be seen in the brown or black, dead leaf margins. In more severe cases the young leaves at the center of the crown were black and dead, as were also the blades of most of the leaves. Many plants showed nothing green but the petioles of the larger 1 For the illustrations used in this bulletin, the author is indebted to Mr. I. H. Blodgett, Assistant Botanist and Entomologist.

In the petioles of the dead leaves the fibro-vascular bun- dles were not blackened except, perhaps, for a short distance below the blackened blade. In the majority of cases the roots appeared normal, but the plants most severely attacked often showed a brown discoloration of the root. This discoloration extended from the outside toward the center for a distance of from one-fourth to one- ~ half an inch. The discolored tissue showed no indication of rot and was separated from the healthy tissue by an indefinite and somewhat irregular line. (See Plate VIII.) The fibro-vascular bundles colored somewhat more deeply than the parenchyma, giv- ing a zonate appearance to the affected tissue. The location of the affected tissue could generally be determined before the root was cut open, by the darker color and pronounced elevation of the bark. (See Plates IV and V.) In some cases when an affected root was cut cross-wise just below the crown the fibro-vascular bundles were found to be much blackened, but this character was by no means a constant one. For a time the writer was puzzled to account for this condition of the beets. The first hint of the true nature of the trouble was obtained from observations made on a field of beets owned by Mr. Clark Crozier, near Halls. This field was level and the soil a sandy loam, with the exception of a small knoll which rose abruptly near the center of the field and consisted of very light, sandy soil. The beets on this sandy knoll were diseased, while those on all the rest of the field were in perfect health. This indicated that lack of water was the cause of the trouble. A severe drought was prevailing at the time and naturally the plants first affected would be those standing in dry, sandy soil. Further observations showed that the beet blight occurred chiefly upon light, sandy soil; but a field near Stanley furnished an exception to the rule. This field, which contained about eight acres, consisted principally of sandy loam, which might be expected to resist drought better than many other fields in the vicinity. As a matter of fact, it was consid- erably blighted, not uniformly, but over irregular areas, although 156 Report oF THE BorTanisT OF THE the soil appeared to be absolutely uniform. However, it should be stated that the blight was most severe along one margin of the field where the ground began to rise a little. The owner of this field stated that early in the season there came heavy rains, which prevented cultivation for a few days. In the meantime the plants ~ became so large that it was decided not to cultivate them any more. The drought then began. The soil became hard and cracked and consequently parted with its moisture more rapidly that it would if it had been cultivated after the rains as were other fields in the neighborhood. The loss of water was still further accelerated by the unusually luxuriant growth of leaves, which was the result of a high state of fertility of the soil. At the time of our first visit to this field, August 29, it was observed that many of the affected plants had thrown out new leaves at the center of the crown. We thought this to be the result of a light shower® which fell August 27, and predicted that growth would very soon be checked unless more rain fell. We were accordingly surprised to find upon our second visit, September 12, that the blight had made no progress. On the contrary, most of the affected plants were putting out young leaves at the crown. (See Plate VII.) On many plants an entirely new crops of foliage had appeared during the previous two weeks. Plants which were apparently dead two weeks before were now green with a crown of new leaves; and this in spite of the fact that there had been no rain worth mentioning* since our former visit. All other affected fields showed similar improvement. A few of the worst affected plants were dead, but the majority were making a second growth. It now became evi- dent that this beet blight was not a gradual drying of the foliage 2 At Penn Yan, .36 inch; at Geneva, .26 inch. 3 The actual precipitation was as follows: At Penn Yan.

Some time during the first two weeks in August, probably about August 9, the weather conditions (temperature, humidity and wind) had been such that the quantity of water transpired by the leaves was greater than the roots were able to supply. As a result the leaves were scorched. Then, with the passing of the conditions which induced excessive transpiration, the roots were again able to meet the demands for moisture thereby enabling the plants to resume growth, although the soil was drier than at the time the injury occurred. Tt has already been stated that some of the plants were killed outright. Upon a third visit to the affected field at Stanley, made October 24, it was observed that these dead roots were still sound except for brown, mostly V-shaped, scab-like areas upon the upper portion of the root. These brown areas represent the later stage of the raised, discolored areas observed on August 29. The tissue was decayed to a depth of from one-eighth to one- quarter of an inch and had been quite generally eaten away hy millipedes, leaving cavities where in the earlier stage of the di- sease there had been elevations. (See Plate VI.) Underneath the affected areas the sound tissne showed the same light brown discoloration as on August 29. It seemed to have progressed, but little, if any. Sometimes the browning occurred in the central portion of the root, but usually it was found only around the circumference and almost always in the form of concentric rings. In the field at Stanley the dead roots quite generally showed the light brown discoloration of sound tissue, but.in an affected field at Bellona it was a common thing to find bad eases of the disease in which there was little or no internal browning. The plants which survived made a considerable growth of new foliage. The roots of such plants did not commonly show any discoloration or decav, but, strange to say, they averaged consid- erably smaller than the roots of plants which had been killed outright. This indicates that the plants which were the largest 158 Report oF THE BoraNnistT OF THE and thriftiest at the time of the injury were the ones most severely affected; and, further, that during two months of second growth the surviving plants increased the size of their roots but little. That the discoloration of the root is a physiological effect (the result of the death of the foliage) rather than the work of any parasitic organism is shown by the results of the following inocula- tion experiment: After the dirt around five healthy sugar beets had been removed there was cut from each a pyramidal cavity one-fourth inch square at the surface and one-half inch deep. These cavities were then filled with similarly shaped plugs of the discolored beet root, the whole covered with grafting wax and the dirt replaced. Five check beets were treated in the same manner except that the cavities were filled with plugs of healthy beet. This was done August 30. On October 18 the beets were pulled and cut open. The inoculated beets showed no discolora- tion of tissue except a slight blackening around the wounds, which was no greater than in the check roots. Some farmers thought that the beet disease was much worse on land where cabbages were affected by black rot in the season of 1898, but our own observations show that there is not good foundation for such belief. It can be stated positively that there is no connection between the leaf scorch of beets and the black rot of cabbage. The amount of damage done to the beets was considerable. Although the majority of the plants recovered, the roots were smaller than they otherwise would have been and their sugar con- tent was lower. Analyses made by Mr. J. A. LeClerc, Assistant Chemist, gave the following results: (1) Roots of plants killed outright analyzed 5.9 per ct. of sugar (in the juice) with a coefficient of purity of 61.6; (2) Roots of plants which had made a second growth after having all their foliage killed analyzed 10.7 per ct. of sugar, coefficient of purity, 73.6; (3) Roots of uninjured plants growing within a few feet of the di- seased plants analyzed 15.2 per ct. of sugar, coefficient of purity, 80.3. New York AGRICULTURAL EXPERIMENT Station. 159 The only other beet leaf disease with which leaf scorch is likely to be confused is a fungus disease known as leaf spot.* This is a common and destructive disease of beets in New York State and is more prevalent in wet seasons than in dry. It forms cir- cular, brown or gray dead spots on the leaves. If the spots are numerous a part or the whole of the leaf may die and turn black in a manner closely resembling leaf scorch, but in such cases the ‘outlines of the spots are plainly visible until the leaf is fully decayed. In the advanced stage, the effects of leaf scorch on the beet root might easily be mistaken for scab. Im general, it may be distinguished from scab by the light brown discoloration of the sound tissue but when the brown discoloration is absent the diagnosis must be based chiefly upon the shape and location of the affected areas. In leaf scorch the affected areas occur prin- cipally upon the upper portion of the root and are usually more or less V-shaped with the opening toward the crown; whereas, in scab the spots occur on any part of the root and are more often irregular or circular than V-shaped. Concerning treatment it is needless to say that proper irrigation is a sure preventive; but where irrigation can not be practiced avoid planting on light, sandy soil and in dry weather conserve the moisture by stirring the soil frequently and especially after every shower. LEAF SCORCH OF CHERRY. Late in September of the present year a Geneva fruit grower ealled our attention to a scorching of cherry foliage which he feared might be an infectious disease like the fire blight of the pear and apple. On trees of all ages more or less of the foliage was brown, crisp and dead. The dead leaves remained attached to the twigs which were neither blackened nor shriveled. A 4 For an account of beet leaf spot and scab and their treatment, see Cornell Exp. Sta. Bul. 163. Three Important Diseases of the Sugar Beet. 160 Report or tue Boranist or TUE brief study of this disease convinced us that we had here to do with a trouble similar to the leaf scorch of beets. Like the beet disease it was most severe on trees standing in dry soil. Upon inquiry among fruit growers it was found to be of common occur- rence this year. The worst case of the disease which has come under our obser- vation occurred in an orchard belonging to Maxwell Bros. near Geneva. This orchard contained 715 Montmorency cherry trees about eleven years of age, the trunks having a diameter of from four to five inches. The trees were set fifteen feet apart each way. Over the whole orchard the soil was uniform and had been thoroughly cultivated. It consisted of a light clay underlaid with slate at a depth of from eighteen inches to two feet. The orchard was located on a gentle eastern slope and was closely surrounded upon all sides by other fruit trees. On October 4 each tree in the orchard was examined and an estimate made of the amount of foliage affected. The result was as follows: 1 tree, 100 per cent. of the foliage affected. 637 trees, 75 to 85 per cent. of the foliage affected. 57 trees, 50 per cent. of the foliage affected. 13 trees, 25 per cent. of the foliage affected. 5 trees, 5 per cent. of the foliage affected. 2 trees, not affected. 715 It is an interesting fact that although six-sevenths of all the trees in the orchard showed 75 per ct. or more of the foliage affected there was but a single tree upon which all of the foliage was killed. The trees were affected with remarkable uniformity. The worst affected trees stood in no particular part of the orchard but were scattered all through it. Although it frequently hap- pened that one side of a tree would be severely attacked while the other half was entirely exempt, there was no uniformity as to the side attacked ; it was quite as often the north side as any PLATE VIII.—CROss SECTIONS OF SUGAR BEETS KILLED By LEAF SCORCH. A. LEAF OF SUGAR MAPLE. LIVING PORTION AT CENTER. B. LEAF OF NORWAY MAPLE. DEAD PORTION AT CENTER. PLATE IX.—MAPLE LEAVES INJURED BY LEAF SCORCH. New Yorx AGricutturaAL Experiment Station. 161 other. Usually, the affected branches were scattered all through the top. Lateral branches were more apt to be affected than main or leading branches, but there were some exceptions even to this rule. If any part of a leaf was affected the whole of it was af- fected, with very few exceptions. The majority of the affected leaves were still hanging upon the twigs on October 4, but they showed a tendency to fall somewhat earlier than the healthy leaves. The twigs were plump and outwardly normal. The cortex was green and apparently normal, but the sapwood was slightly discolored. ‘This discoloration was most pronounced on twigs of the present season’s growth, but was noticeable all along the branch. The foreman in charge of the orchard states that the disease appeared rather suddenly, although not quite all at once and that it occurred about August 20. The orchard was affected in a similar manner in 1898, but not so severely. In 1898 the scorch- ing appeared in July before picking was all done and it was feared that the following crop would be considerably lighter because of it. However, such was not the case. The crop of 1899 was a heavy one and there were no visible effects of the scorching of the foliage the previous summer. This orchard was also slightly affected in 1897. It appears that cherries are much more liable to this sort of injury than are pears, plums or apples. Scattered through the affected cherry orchard there were a few small pear trees which had been planted to replace dead cherry trees. None of these pears showed any sign of leaf scorch; neither did the pears lo- cated at A (see Plan) on the same kind of soil. Plum trees at C and F immediately adjoining the diseased cherries were in perfect health. The several different varieties of apples at E were also unaffected. The English Morello cherries at B were considerably affected but not so severely as the Montmorencies. The Montmorency orchard at D was composed of young trees and situated upon moister and deeper soil. However, a good aa 162 Report or THE BoranistT OF THE many trees were slightly affected, especially those standing in the corner of the orchard near the old Montmorency orchard. i H i 1 ' ' ! ! !

New Yorx AGRICULTURAL EXPERIMENT STATION. 163 In no other orchard examined have the trees been so uniformly affected as in this one; perhaps because in no other case have the soil and conditions been so uniform. In general, trees af- fected in varying degrees up to one-half of the foliage have been found freely intermingled with perfectly healthy trees; but when an orchard was situated partly on dry and partly on moister soil, the disease was invariably worst on the trees standing in the dry soil. In one orchard of large trees of Montmorency the disease was confined chiefly to the lower branches. A cherry grower at Hector states that in his orchard the trees were generally affected upon the south side, but in the orchards about Geneva we have not observed that the south side of the tree is more often affected than any other side. Trees standing in exposed situations have been no more affected than sheltered trees. As to the time the injury occurred there is a difference of opinion among fruit growers. Some believe that the injury came on gradually, but the majority are of the opinion that it occurred within a comparatively short space of time. Some say it occurred early in August, others about the middle of August and one is certain that his orchard was not affected until the first week in September. It is not improbable that there were two periods when the weather conditions were favorable to the scorching of foliage. One occurred some time during the first half of August and the other on Sunday, September 3. On the latter date the temperature was high, the air dry and a strong wind blow- ing. The writer expected much injury to result from this, but observed none whatever. Nevertheless, cherries in some situa~ tions may have been injured. Some have attributed leaf scorch to over-bearing, but there is no evidence to support this theory. In many cases trees which have never borne fruit have been severely affected. It is possible that fruit-bearing tends to increase the liability to the disease, but even that remains to be proven. 164 Report oF THE BorTanist OF THE Accurate information is lacking as to the susceptibility of dif- ferent varieties. Montmorency® has been more commonly af- fected than any other variety, but English Morello and some other varieties have shown it to a considerable extent. From the experience of Maxwell Bros., it would appear that little harm is likely to result from this scorching of the foliage, but it seems incredible that a cherry tree can lose a large part of its foliage in July or August without affecting its productiveness. The effect must be the same as if the leaves were removed at this time. We shall watch the Maxwell orchard with interest the coming season. LEAF SCORCH, OR TIP BURN, OF CAULIFLOWER. On September 1 Mr. F. A. Sirrine, Entomologist at our Branch Office on Long Island, sent to the Station some cauliflower leaves the margins of which were blackened and shriveled. The di- seased leaves were accompanied by a letter saying that throughout eastern Long Island the partly unfolded leaves of cauliflower were quite generally affected in this manner. On September 7, in company with Mr. Sirrine, the writer visited some of the af- fected cauliflower fields in the vicinity of Mattituck. At this time the affected leaves were growing and appeared normal ex- cept for their crisp, brown or black margins. The newest leaves were entirely free from the trouble showing that the cause of the blackening was not then active. It was quite plainly another case of leaf scorch. Large plants were more severely injured than small ones. The worst affected field observed was one in which the plants were very large and thrifty and had commenced to form heads.® As with the beet and cherry, the exact time the injury occurred is unknown. It occurred some time during the last ten days of August. Although the rainfall for August in this section was 5 The Montmorency grown at Geneva is Montmorency Ordinaire. 6 Cauliflower was not generally heading at this date, September 7. New York AGRICULTURAL EXPERIMENT STATION. 165 very light (.75 inch at Cutchogue) there was considerable fog. Mr. Sirrine states that there was continuous fog from August 18 to 20, inclusive, and some each day for a week following this period, but no rain fell between August 13 and 31. It is our opinion that the injury was caused by the hot sun falling upon young leaves which were unusually tender because of having grown in foggy weather. Tip burn should not be confused with the bacterial disease ealled black rot’ of cauliflower, cabbage and related plants. Both diseases may occur in the same plant, but many plants affected with tip burn show no blackening of the fibro-vascular bundles —the most reliable diagnostic character of the black rot. Tip burn affects the margins of the young leaves, while black rot attacks chiefly the old leaves and when it does occur on young leaves shows itself throughout the whole leaf rather than at the margin. ; The amount of damage done by tip burn of cauliflower has been small. LEAF SCORCH OF NORWAY AND SUGAR MAPLES. The Norway maple, Acer platanoides, is much subject to injury from excessive transpiration. In New York more or less of it occurs nearly every season. It is most common on recently transplanted trees, but very frequently occurs on rapidly growing nursery stock and in very dry seasons may be observed also upon large shade trees. During the past season this maple leaf scorch has been been unusually common. Besides attacking the Norway maple it has been common on the sugar maple, Acer saccharinum. In the course of a half day’s drive in Central New York during last Au- gust or September one might see along the roadside, perhaps, a hundred or more sugar and Norway maples on which more than half of the foliage was brown Many slightly affected trees would also be seen. 7 Pseudomonas campestris (Pammel) Smith. 166 Reprort or THE Boranist OF THE If the injury is severe and occurs before the leaves are fully grown, the injured leaves fall and new ones appear, but if the injury occurs after the leaves are full grown they remain attached to the twigs until late in autumn. In the latter case some of the leaves will be found wholly dead, but the majority of them will show a dead, brown portion and a living, green portion. As a rule, especially on the sugar maple, the dead portion is located around the margin of the leaf (see Plate IX, fig. A), but it may occur in the form of circular or irregular blotches; or the margin of the leaf may be occupied by living, green tissue surrounding a dead area at the center (see Plate IX, fig. B). Im all cases the living tissue is separated from the dead by a sharply defined line. The color of the dead tissue is either light brown or reddish brown. The injured leaves for the most part remain expanded. As with the beet, cherry and cauliflower, this injury to maple foliage occurs in a comparatively short space of time. It happens whenever the quantity of water transpired by the leaves is greater than that which the roots are able to supply; and this condition of things may be brought about in several ways. Some of the factors which enter into the problem are: Area of leaf surface exposed, quantity of water in the soil, activity of the roots, and location of the tree as regards exposure to wind. Having in mind these several factors, it is easy to understand how one tree may be seriously injured while another tree standing close beside it may not be affected at all. This is of common occurrence. In nurseries the disease often escapes notice until the dead leaves have become overgrown with various saprophytic fungi which are likely to be mistaken for the cause of the trouble. Trees recently transplanted may die from the effects of leaf scorch, but established trees rarely show any permanent injury. 8 Observations upon the scorching of immature maple foliage have been re- ported by Stone, G. E., and Smith, R. E. Wilt of Maple Leaves. Ninth Ann. Rept. Hatch Exp. Sta., of Mass. Agr. Coll.: 81-82; also by Stewart, F. C. Norway Maples Injured by Dry Winds. Fifteenth Ann. Rept. of this Station: 453-454. New York AGRICULTURAL EXPERIMENT Station. 167 There is a fungous disease of the Norway maple which might be mistaken for leaf scorch by one unfamiliar with the latter trouble. This is an anthracnose®, Gloeosporium apocryptum EK. & E., which attacks the leaves and young shoots. It is most severe on small trees, especially nursery trees, occurring but rarely on large shade trees. It attacks chiefly the terminal shoots, often transforming them into much branched “heads.” The leaves are dwarfed and have a yellowish green color, with the margins curled downward and blackened as if slightly frosted. ‘This disease is prevalent in Long Island nurseries and lias been observed at Geneva the present season on nursery trees and small shade trees. 9See Fourteenth Ann. Rept. N. Y. Exp. Sta., 1895: 531-532. NOTES ON VARIOUS PLANT DISEASES.* F. C. Stewart. SUMMARY. I. During the season of 1898 a bacterial rot caused heavy losses to the onion growers in Orange Co., N. Y. The onions were found to be affected at harvest time. One or more layers of the onion would be soft rotten while the adjacent layers were sound. Sometimes the rotten layers were on the interior, in which case the affected bulbs might be difficult of detection; or the rot might be confined to the outermost fleshy layer, producing the so-called slippery onions. Although this rot is quite certainly due to bacteria, it is not readily produced by inoculation with diseased tissue except in the presence of water. This shows that water is an important factor in the rot and that the unusually large amount of rot in 1898 was due to the excessively. wet weather which oc- curred in July and August of that year. Thorough drainage and clean cultivation are recommended as preventive measures. II. Leaves of field cucumbers affected with a powdery mildew have been received from Athens, Pa. This is believed to be the first record of the occurrence of powdery mildew on field-grown cucumbers in America. In greenhouses it isnot uncommon. The - identity of the fungus is uncertain, but it is probably different from the powdery mildew occurring on squashes and pumpkins. III. A dodder, Cuscuta gronovia Willd., has occurred on green- house cucumbers at the Station. Plants affected with this parasite should be immediately destroyed to prevent it from spreading. It is very aggressive. * Reprint of Bulletin No. 164. New Yorx AGRICULTURAL EXPERIMENT STATION. 169 IV. The disease of Baldwin applies, known in New York as the Baldwin fruit-spot, is characterized by small brown sunken spots which occur on the fruit about the time it is gathered. Un- | derneath the spots the tissue is ight brown and spongy. ‘The diseased tissue contains no fungus hyphe. In moist chamber the spots do not enlarge and no fungus appears on them. On various culture media the affected tissue produces no growth. The con- clusion is that the disease is not caused by fungi or bacteria. How- ever, the work of other investigators indicates that similar spots on the Baldwin and other varieties may be due to parasitic organ- isms and hence the desirability of greater care in the writing of descriptions. V. A species of Fusariwm has been found producing a serious leaf spot disease of carnations at Syracuse. It occurred upon plants so situated that the direct sunlight could not reach them. The fungus gains entrance through breaks in the epidermis made by rust sori. It is not improbable that it may be identical with the carnation stem-rot Fusarium. VI. Chaetomium contortum Pk., a rare fungus hitherto found only on lily bulbs on Long Island, has occurred at Geneva under circumstances which aroused the suspicion that it is parasitic on barley seedlings; but an inoculation experiment showed that it is not parastic. I. A BACTERIAL ROT OF ONIONS: In the autumn of 1898 the report came to the Experiment Station that the onions in Orange Oo., N. Y., were rotting badly. Upon investigation it was found that in nearly all of the fields in this great onion growing district there was a considerable amount of rot. In many cases from one-third to one-half of the crop had to be rejected on account of it, and the remainder was not readily salable because news of the rot had reached New York city pro- 1 This paper was read at the Columbus meeting of the Society for the Pro- motion of Agricultural Science, August 22, 1899, and will subsequently be published in the Proceedings of that Society. 170 Report oF THE BoTANIST OF THE duce dealers who were accordingly suspicious of all onions coming from Orange Co. The same rot was also common in the onion fields of Madison Co., but the losses from it there were not nearly so great as in Orange Co. The rot was of two kinds: (1) One which starts at the bottom of the onion, and (2) One which starts at the top or “ neck.” The latter kind of rot was much the more common, constituting perhaps eighty per ct. of the total amount of rot. Where the rot had started at the top the bulbs were frequently sound in ap- pearance, but rotten within. Oftentimes it was difficult to deter- mine, before cutting, whether or not a bulb was rotten. In sort- ing, the customary test for soundness was to press down with the thumbs close about the “neck” of the onion. If it was hard the bulb was sound, but if soft it was usually rotten inside. Onion growers speak of such onions as being “ weak in the neck.” Upon cutting open the affected bulbs it was generally found that two or three of the outer scales were perfectly sound while the remainder of the bulb was a rotten mass. Frequently a single scale would be entirely rotten from top to bottom and clear around the bulb, while the remaining scales upon both sides of it, were perfectly sound. Such specimens cut crosswise showed the rotten part in the form of a ring. (See Plate X.) Again, a perfectly sound scale would be found between two rotten ones. (See Plate XI.) The rot appears never to spread from one scale to another later- ally, and this peculiarity furnishes the most reliable means for the identification of this rot. The organism causing it is unable to pass through the uninjured epidermis of the scale. The passage from one fleshy layer to another is effected at the base of the bulb where they unite. Upon reaching the base of the scale in which it is working the rot commonly stops, and this accounts for the large number of cases in which one or two scales are rotten while the remainder of the bulb continues sound. Under certain con- ditions the rot does not stop at the base, but works its way into the bases of other scales which it then follows upward destroying the whole bulb. ‘LOY IVIUDALOVAG HLIM AALOAAAY SNOINO—' yi ‘SHTVOS NELLOY NAAMLAG #1NG NOINO HO S#IvoOg GNNOS—TX dLvig ; New York AGRICULTURAL EXPERIMENT Station. 171 When the rot is confined to the outermost fleshy scale, as is frequently the case, the atfected bulbs are called “slippery onions.” Some of these are to be found in any season, but they are rarely so abundant as to cause material loss. Microscopie examination of the rotten tissue shows entire ab- sence of fungi, but there are swarms of a medium-sized motile bacillus which is without doubt the immediate cause of the rot. When the rot commences at the bottom of the bulb the whole lower part is soft and eventually the entire onion becomes in- volved. The rot spreads upward through all of the scales simul- taneously. Bulbs so affected show a profuse growth of Fusarium about the base and the rotten tissue is filled with the Fusarium hyphe mingled with the previously mentioned bacillus. Although the presence of the bacillus is sufficient to account for this base rot it seems probable that the Fusariwm aids materially and in some cases it may be the primary cause. By inquiry among onion growers it was learned that there is in nearly every season a small amount of loss from rot which usually appears in the form of “ slippery onions,” although both the center rot and the base rot have long have been known. The note worthy fact in connection with the rot in 1898 is the unusually large amount of center rot. | The rot was noticed by farmers when the crop was harvested in August, but the full extent of the trouble was not realized until a month later when the crop was sorted for market. At first it was attributed to injury from hail which fell on July 30; but later the hail theory was rendered untenable by the discovery that there was considerable rot in fields which had not been struck by the hail. Probably, the wind accompanying the hailstorm was a much more important factor in the rot. In nearly all of the onion fields the tops were much broken by the wind. Among stored onions kept reasonably dry the rot progresses very slowly, but wet onions rot rapidly, especially if the temperature is high. 172 Rerort or Tue Boranist OF THE All of the evidence obtainable goes to show that this bacterial rot is not new, but that it is an old enemy which found unusually favorable conditions for its development in some peculiarity of the weather during the season of 1898. As yet, no attempt has been made to determine the identity of the organism causing it. It may be the same as the one causing the rot of onions and other plants observed by Halsted? in New Jersey. The weather records published by the New York State Weather Bureau show that the rainfall in Orange Co. was excessive and the temperature high from the middle of July to the close of August, 1898. At Middletown, which is on the edge of the onion district, the dates upon which rain fell* during this period were as follows: RAINFALL AT MIDDLETOWN, N. Y., JuLy 18 To AuaustT 26, 1898. Date.

It is a favorite method with plant disease committees to send out circulars of inquiry to fruit growers asking for information concerning fruit diseases which have appeared during the season. We have done this and gotten considerable valuable information; but this method is applicable only to a few of the most common and best known diseases. In the first place the majority of fruit growers will pay no attention to such a cireular. Out of a total of 250 circular letters enclosing self addressed envelopes for the reply we have jhad returned to us only 59. Secondly, the replies are often misleading. They are usually based not upon care- ful observations properly recorded, but upon loose general impres- sions. Furthermore, the laity are able to identify accurately only a very few diseases. Frequently, two or more distinct diseases pass under one common name. Blight, leaf-spot, rust, fruit-rot and root-rot are examples of this. What is commonly called pear leaf- spot is caused by two quite different fungi, but there are very few persons not experts who know the difference between them. We have in New York, three fungous diseases and an insect trouble which are covered by the one common name, currant leaf-spot. Even so well known a disease as peach leaf curl is sometimes con- fused with the distortions caused by plant lice. 2The records for April, May, and June, are taken from the U. S. Monthly Weather Review; those for July, August, and September, from the N. Y. Cli- mate and Crop Service monthly reports. 8 The August record for Poughkeepsie is lacking; the figures here given are for Wappinger’s Falls, the nearest record station. 188 Report or THE Boranist OF THE Appreciating the limitations and inaccuracies of the circular- letter method, the committee planned to supplement the data ob- tained in that way with data obtained from observations made by experts. or this purpose the Chairman associated with himself Mr. F. H. Blodgett, Assistant Botanist and Entomologist, who made three two-day and three three-day trips to different localities in the southern half of the district for the purpose of inspecting fruit plantations, taking notes on fruit diseases and collecting speci- mens. The Chairman made six similar trips of inspection to locali- ties in the northern half of the district. This combination of circular-letter method and expert inspection is a good one. The two methods supplement each other admirably. The following is a copy of the circular letter sent to fruit growers, the spaces for answers being omitted: CrrcuLar LETTER oF INQUIRY SENT TO FRUIT GROWERS. GENEVA, N. Y., Nov. 15, 1899.

COVERT, Committee. MAGNITUDE OF THE FRUIT INDUSTRY. Fruit growing is one of the leading industries throughout the whole district. In several localities it is practiced to the exclusion of all other branches of agriculture. The most prominent of these special fruit growing localities is in the southeastern part of Ulster County around Marlboro, Milton and Highland. The fruits grown extensively are apples, cherries, currants, grapes, peaches, pears, raspberries and strawberries. There are several commercial plantations of gooseberries, blackberries and 190 Report or THE Boranist of THE quinces. Plums are grown to a considerable extent, but not so much as formerly. Apricots and dewberries are rare. There are but few nurseries in the district. GENERAL STATEMENT OF RESULTS. Fruits generally have been remarkably free from diseases of all sorts. Nearly all fruit growers with whom we have talked upon the subject say that all fruits have been freer from disease the past season than for many years. There has not been an epidemic of any disease and some of the common destructive diseases have been almost entirely absent. Fruit diseases have been conspic- uous by their scarcity. Consequently, quite as much is said in this bulletin about what has not been found as what has been found. It is to be regretted that a thorough survey of fruit diseases in the Hudson Valley was not made in 1898. The season of 1898 was very wet and fruit diseases generally were unusually destructive. A comparison of the two seasons would be instructive. The replies to questions two and six of the circular letter were so few and so unsatisfactory that they have not been considered. The replies to questions four and five indicate that Bordeaux mix- ture, although used to a considerable extent, is not in as general use as it should be. APPLE DISEASES. In quantity, the apple crop of 1899 was, perhaps, no more than an average one; but the fruit was remarkably fair, being un- usually free from blemishes of all sorts. Nevertheless, apples have not kept well. This is due partly to the warm autumn? and partly to the fact that the fruit ripened prematurely. Certain winter varieties, for example Baldwins and Greenings, have in some cases behaved more like late fall varieties. 4 This statement does not apply to insect injuries. 5 It is believed by some that the very heavy frost on October 3 (25° at Honey- mead Brook, 27° at Wappinger’s Falls), seriously injured the keeping qual- ities of apples. New Yorx AaricutturaL Exprertment Sration. 191 SCAB. (Venturia maequalis (Cke.) Adeh. Syn. Fusicladium dendriticum (Wallr.) Fcekl.) This arch enemy of the apple has done very little damage. It has been reported as occurring to a slight extent in all the counties in the district except Albany, Ulster and Putuam, but only one correspondent (Old Chatham, Columbia Co.) reports it trouble- some. On June 20 we sought in vain for a single specimen of scab in an 80-acre apple orchard at Poughkeepsie. In 1898 this orchard suffered severely from scab. At Washingtonville scab spots were common on the twigs of the Lady apple, which is a variety very susceptible to this form of attack. LEAF SPOT. (Phyllosticta spp.) What a correspondent thought to be leaf spot occurred injuri- ously at Schodack Landing, Rensselaer Co. In some orchards 25 per ct. of the foliage was affected. Upon investigation it was found that the so called leaf spot was the work of an insect,® the resplendent shield-bearer (Aspidisca splendoriferella). The true fungus leaf spot has been much less common than scab, but traces of it have occurred at various points in the district. No attempt was made to distinguish between the two species. TWIG BLIGHT. (Bacillus amylovorus (Burr.) DeToni.) Rare. A few affected twigs were observed in Albany Co.; and three correspondents, one each in Orange, Ulster and Rensselaer counties, report its occurrence in small quantity. 6 On the authority of Mr. F. A. Sirrine, who examined some of the affected leaves. 192 Report oF THE BorTanist OF THE CANKER." (Sphaeropsis malorum Pk.) This disease has killed a good many Spitzenberg trees in the vicinity of Voorheesville and New Scotland in Albany Co. It occurs destructively at Pomona and Blauvelt in Rockland Co. At Blauvelt it is especially troublesome on the variety Sour Bough. It has also been observed at Yorktown and Poughkeepsie. SOOTY BLOTCH. (Phyllachora pomigena (Schw.) Sace.) Rare. A little found on apples received from Newburgh and Yorktown. RUSSETING OF FRUIT. Russeted apples are reported to have been common in the vicinity of Hudson. We have seen the disease on Baldwins and Ben Davis at Poughkeepsie. The affected fruits were frequently misshapen and showed irregular areas on which the skin was rough and light brown in color. This appearance is sometimes due to spraying and sometimes to weather conditions alone.® It is often incorrectly called rust. RUST. (Gymnosporangium spp. Syn. Roestelia spp.) This is a fungous disease in which circular yellow spots appear on the leaves in June. It may attack the fruit also. The red cedar, the host of the teleuto stage of the fungus, grows spontane- ously throughout the entire district and “cedar apples” were found quite commonly upon it during early May in Ulster and Rockland counties; but the ecidial stage upon the apple has been entirely absent. 7 For an account of Apple Canker, see Bulletin 163 of this station. 8 See Bulletin 84 of this station, pp. 29-33. New Yorx AGRICULTURAL EXPERIMENT STATION. 193 SUN-CRACK. On June 2 some apple-tree trunks were observed at Ghent on which the bark was loose and dead over areas from two to four inches in width and from one to four feet in length. These in- juries were on the southwest side of the trunks and usually, but not always, extended quite to the ground. It first appeared in the spring of the present year. ‘The trees were unusually thrifty, about seven years old and of the variety Willow Twig. They ‘stood in well drained soil. We are of the opinion that it was caused by the sun’s rays heating the bark intensely in early spring while the soil about the roots was still deeply frozen. That is to say, this is a case of what Hartig® calls sun-crack (Sonnenriss). A sun-erack or perhaps sun-scald of apple tree trunks locally known as “southwest blight” is of common occurrence in the vicinity of Washingtonville. BROWN, SUNKEN SPOTS ON THE FRUIT.” A disease of this description has been reported as occurring on Greenings and Baldwins at Clintondale. APRICOT DISEASES. Apricots are not cultivated to any extent within the district. The only disease with which we met was one occurring at Ghent. Some trees which have been planted for several years have been dying off mysteriously one at a time for a few years past. A tree may die either in part or wholly at any time during the growing season. Some died in the spring of 1899. Just above the surface of the ground the bark is dead, often for considerable distance up the trunk; but the wood is not laid bare. Sometimes the bark shrinks 9 Hartig, R. Text-Book of the Diseases of Trees (p. 296). Translated and revised by Somerville and Ward. The Macmillan Co.: New York, 1894. Dr. Hartig informs us that Fig. 159, which purports to illustrate sun-crack, is misnamed. The injury was caused by lightning. 10 A description of this disease and an account of an investigation into its causes are given in Bulletin 164 of this station. 135 194 Rerort or true Boranist oF THE tightly to the wood. Between the bark and the wood there may be much fungus mycelium, probably the mycelium of Irpea lacteus Fr. since pilei of that fungus were found on one of the dying trunks. One of the diseased trees was dug up for the purpose of examining the roots, which were seemingly healthy and free from fungus. ‘There was no sharp line of demarcaticn between the dis- eased and healthy wood at the point where the scion joined the stock. The trees were thrifty, having been well cultivated and eared for. The cause of this disease is unknown to us. It occurs in other parts of the state, sometimes causing heavy losses. BLACKBERRY DISEASES. ORANGE RUST. (Puccinia peckiana Howe. Syn. Caeoma nitens Schw.) Orange rust, although less distructive than usual, was abundant and undoubtedly the worst blackberry disease. For several years W. D. Barns & Son of Middle Hope have persistently fought the disease by digging out and burning the affected plants. It is probable that this treatment has materially lessened the ravages of the disease, but in spite of their efforts it continues to cause con- siderable damage every season. To get the best results from such treatment the diseased plants should be removed promptly upon the first appearance of the disease to prevent the spores from ripening. At Mr. Barns’ place our attention was called to an interesting effect which rust has upon the canes of raspberries and blackberries, Canes affected with rust were much freer from prickles” than were healthy canes. These observations were made on May 8, at which time the rusty canes of the preceding season’s growth were easily recognized although the ecidiospores were not yet mature. Among’ black- 11 The stock was peach. 12No reference to this phenomenon has been found in the literature at hand. Mr. W. Paddock informs us that he has observed it at Oaks Corners, Ontario county.

PLATE XV.—A HEALTHY AND A RUSTED BLACKBERRY CANE FROM THE SAMB HI. 4 New Yorx AGRICULTURAL ExpEeRIMENT Sration. 195 berries of the variety Wilson Jr., the rust-affected canes were almost or even wholly destitute of prickles. It is not an uncom- mon thing to find healthy canes and rusted canes of blackberry in 1.48 Such cases offered an opportunity for close com- the same hil parison and it was found that the difference in the number of prickles on the two sorts of canes in the same hill was very marked. (See Plate XV.) The difference is so great that Mr. E. W. Barns says he can pick out the diseased canes in winter by their freedom from prickles. On affected raspberry canes the reduction of prickles was very evident but not so marked as with the black- berry. After these observations at Middle Hope, we examined, during the season, many rusty blackberries, raspberries and wild dew- berries (Rubus canadensis L.) in various localities. With all of these plants we found that rust in some cases caused a great re- duction of prickles; in other cases, partial reduction; and in still others, no reduction at all. At Yorktown badly rusted blackberries of the variety Minnewaska were observed which showed no ap- parent reduction of prickles. 4 LEAF SPOT. (Septoria rubi Westd. ) Rare. Observed only at Poughkeepsie. CHERRY DISEASES. FRUIT ROT. (Monilia fructigena P.) As usual, fruit rot has been the worst cherry disease, but was not nearly so destructive as in 1898. From Westchester Co. it is reported “ bad on some varieties.” In Rockland Co. it destroyed 13 This has also been observed by Clinton; Orange Rust of Raspberry and Blackberry. Ill. Agr. Exp. Sta. Bul. 29: 276. D. 1893. It occurs less com- monly with the raspberry, probably on account of the more compact habit of growth at the crown. 196 Report oF THE BovranisT OF THE about 25 per ct. of the latest sweet cherries. Orange Co. cor- respondents report but little damage from it. At Kinderhook, Columbia Co., it was “ unusually developed.” In the vicinity of Delmar, Albany Co., it is reported to have destroyed about 10 per ct. of the crop; and in one orchard about 50 per et. A cor- respondent at Highland, Ulster Co., reports the loss of one-half his crop; but from personal observations we would say that, in gen- eral, cherries suffered but little from rot in that locality. LEAF SPOT. (Cylindrosporium padi Karst.) This disease has occurred in small amount over the whole dis- trict, but no case has been reported in which it has done serious damage. BLACK KNOT. (Plowrightia morbosa Sace.) Throughout the Hudson Valley black knot is common on eulti- vated cherries of some varieties. English Morello probably suf- fers most. Trees of this variety are frequently ruined by it. At Middle Hope, Orange Co., Montmorency and Early Richmond cherries are said to knot considerably. At Coxsackie, Greene Co., we found knots on English Morello cherries producing summer spores as early as June 1. Black knot is exceedingly common on plums over the whole district. In former years it has been a veritable scourge. With these facts before us it is an interesting observation that, although the wild black cherry, Prunus serotina Ehrh., is very common and we have searched carefully, not a sin- ‘ ple specimen of black knot has been found upon it. The wild red cherry, Prunus pennslyvanica L. f., is common in Albany Co., but we have failed to find any affected by black 14 Peck, also, has noted the absence of black knot from Prunus serotina in Eastern New York. See Forty-Second Ann. Rept. N. Y. State Mus. Nat. Hist.. 3888: 125. On Long Island, black knot is abundant on this species. ‘ New York AGricuLTuRAL EXPERIMENT STaTIon. 197 knot. In the central part of Rensselaer Co. we have examined the choke cherry, Prunus virginiana L., which grows wild there, but found no knots upon it. However, at Washingtonville, Orange Co., the latter species is said to be much affected. What has been said applies only to old knots. The observa- tions furnish no information as to the number of knots produced by infections occurring in 1899, for the new knots do not appear until late in autumn, after the time when the survey was finished. WITCHES BROOMS. (Exoascus cerast (Fckl.) Sadeb.) Knowing that this disease is not uncommon in some other parts of the State’ we expected to find it in the Hudson Valley, but failed to find a single specimen. POWDERY MILDEW.

TREATMENT FOR GOOSEBERRY MILDEW.* G2 P. Cioss. SUMMARY. For three seasons, Bordeaux mixture, lysol and formalin have been compared with potassium sulphide, the latter giving the best results in all three series. The Bordeaux mixture proved comparatively valueless, as in but one series of tests did treated bushes show less mildew than check bushes; formalin in the strongest solution, 1 oz. to 1 gal. water, gave fair results, but weaker solutions ranked with the Bordeaux mixture; lysol gave promising results, coming next to the potassium sulphide in reduction of mildew injury. With one exception, Bordeaux mixture, very early spraying gave better results than medium early or late treatments. Winter treatment was tested during one season, but did not give sufficiently favorable results to justify recommendation. INTRODUCTION. The gooseberry mildew generally makes its appearance during the last half of May or first half of June. It is first noticed as glistening, frost-like spots on the fruit on the lower part of the bush where there is usually dense shade. As the disease progresses the spots enlarge, turn dark brown and form a felt like covering over a part, or all, of the berry. In a slight attack the disease * Reprint of Bulletin No. 161. 21 322 Report oF THE HorTICcULTURIST OF THE may not injure the fruit at all, or only slightly deform it. In a bad attack the fruit has a repulsive appearance, is stunted in develop- ment, and may be more or less decayed. Two or three weeks after the mildew attacks the fruit it appears on the young, tender twigs, especially on their tips. If the attack is severe the new growth will be destroyed and the older growth will be considerably injured. In case of a very severe attack the fruit will be rendered worthless, and the foliage will be nearly, or entirely, killed during July. As a result no fruit buds are set for the next year’s crop, and the bushes are so badly weakened that they may suffer from winter injury. In a few commercial plantations where little or no spraying has been done the writer has seen the crop of fruit destroyed and the bushes practically ruined by this disease. In other plantations where spraying was carefully done the greater part of the crop was saved, the foliage remained in good condition and fruit buds were set for a succeed- ing crop. The extent to which mildew can be prevented by spraying depends upon weather conditions and location. In a wet season like that of 1898 it flourishes abundantly and is difficult to control. The disease, as already stated, usually obtains a foot- hold on the lower parts of the bushes where the shade is dense. These parts are very difficult to reach thoroughly with spray solutions, and in a year when the other conditions favor the spread of the fungus, are liable to harbor more or less of the disease unless the greatest care and thoroughness are used in spraying. In a dry season like the present one mildew ean be almost entirely prevented by thorough use of fungicides. On uneven ground the higher parts of a plantation seem to be less subject to the disease than the lower parts. The best location seems to be one well elevated, with a gradual slope affording good air drainage. In view of the destructive character of gooseberry mildew and its economic importance in all parts of America where gooseber- ries are grown, either for home use or for market, it was decided to undertake experiments in treating the disease on a commercial scale. The object of the experiments was to compare the potas- sium sulphide treatment with treatments with other fungicides Explanation of Diagram. a ee No coor CE XXXXXXXXXN % Formalin loz.torfgalswate t. : | Bl x Xx x x x x x oo be x x Lysol lozto Haals. water.

These investigations were begun in 1897 and have been con- tinued for three seasons. Two commercial plantations have been under experiment. One belonging to Kg & Robinson is located at Trumansburg on the slopes just west of Cayuga Lake. This was treated three seasons. The other belonging to the Van Dusen Nursery Co., Geneva, and located on the upland about two miles west of Seneca Lake, was treated in 1899 only. A preliminary report giving the results of the work in 1897 may be found in Bulletin 133. A complete report of the investiga- .ons for the entire period from 1897 to 1899 is now presented for the first time. TRUMANSBURG EXPERIMENTS. PLAN. The plantation at Trumansburg consists of 32 rows with 11 plants to the row. As shown in the diagram opposite it was divided into six plats. Each treatment was given to two plats located in different parts of the plantation. This arrangement wes “or the purpose of equalizing for each remedy the differences in soil and location which might exist in different parts of the plantation. For convenience in comparing the effects of very early with medium and late spraying, three series of treatments were made. Series I was begun very early just as the buds were breaking and successive applications were made at intervals of about ten days until seven had been given. Series II was begun when the second spraying of Series I was made. Series IIT was begun when Series I received its third spraying and Series IT its second sprayin~ During the remainder of the season the dates of treat- ment were the same for all three series. An untreated row was left as a check for each series. 324 Report oF THE HorvTicuLTuRIST OF THE FUNGICIDES USED. Bordeaux mixture (ordinary), 1 to 11 formula, was used until the last two or three sprayings when potassium sulphide, 1 oz. to 2 gallons water, was substituted for it. This substitution was made so that the fruit would not be spotted with Bordeaux mix- ture at the time it was picked for market. Lysol and formalin were each used in three strengths, 1 oz. to 1 gal. water, 1 oz. to 2 gals. and 1 oz to 4 gals.; and potassium sul- phide in two strengths, 1 oz. to 2 gals. and 1 oz. to 3 gals. water. Applications of these materials were made with a bucket force pump fitted with a Bordeaux nozzle. No injury was done to the foliage by any of the solutions. OBSERVATIONS AND DATES OF TREATMENTS. Tests in 1897.— The first spraying was made April 12 just as the buds were bursting. This was followed by applications April 23, May 5, 17, 26, June 7 and 21. The bushes made a good growth and had a good setting of fruit. Mildew was found in small amounts on the fruit May 26. This developed rapidly on the fruit and by June 7 had spread to the new growth. A careful examination revealed less mildew on the bushes treated with potassium sulphide than on the other treated or untreated bushes. As it was desired to market the fruit green, the last spraying was made June 21 and the fruit was picked early in July. Tests in 1898.— Owing to the very mild weather early in March the buds began to open and by the middle of the month were in condition for the first spraying. They were not sprayed, however, because it seemed that cold weather must come and check the premature growth, hence it would be useless to spray until continuous growth might be expected. Contrary to expecta- tion the latter part of March was not unfavorable to a slow growth and by April 1 when the first spraying was made the growth was about ten days in advance of what is desirable at the time of first application. Later applications were made April 14, 26, May 9, 21, June 1 and June 13. There was an abundance of moisture AW, T7E NN PLATE XXVI.—CROWN BOB GOOSEBERRY AFFECTED BY MILDEW.

The disease was first noticed May 25. It was quite gen- erally distributed throughout the plantation but was most abun- dant on the untreated rows. The fruit was marketed green the latter part of June. Tests in 1899.— The weather was unfavorable to early growth so the first spraying was not made until April 15. Later spray- ings were made April 25, May 5, 15, 25, June 6 and 12. The season was dry and the attack of mildew was compara- tively light, although the bushes made an excellent growth and set a fair crop of fruit. Mildew appeared early in June and was especially noticeable on the check rows and on the under side of bushes sprayed with Bordeaux mixture. The young growth was exempt from the disease. The fruit was picked the last of June. RESULTS.

This shows 40 per ct. less mildew than the check rows do. A weaker solution of the same material gave the next best results and here again the very early treatment of Series I is most favorable, being 28 per ct. better than un- treated. The results with lysol are promising, the strongest solution, 1 oz. to 1 gal. water, reducing the amount of mildew 18 per ct. With formalin, the treatment in Series I, using 1 oz. to 1 gal. water, was much the best, reducing the amount of mildew 14 per ct. In most other cases the tests with formalin rank with the results obtained from the use of Bordeaux mixture, which in Series II only is better than the untreated rows. In Series I and Series III the tests with Bordeaux mixture actually show a larger percentage of mildew than do the check rows. With the exception of Bordeaux mixture in Series II the very early treat- ments of Series I gave the best results with all tests. The cost of the material for the remedy giving the best results, potassium sulphide, 1 oz. to 2 gals. water, is about three tenths of 1 cent per bush for seven applications per season. New York AGricuLturaAL Experiment Station. 3827 GENEVA EXPERIMENTS. PLAN. The tests were carried on in the Industry plantation of the Van Dusen Nursery Co., near Geneva. During the past few sea- sons the attacks of mildew here were so severe that the crops were destroyed and many bushes had been either killed outright or so badly weakened that they were winter killed. The part of the plantation used for this work contained 28 rows, 20 bushes to the row. The general plan of the work in this plantation was much like that for the work done at Trumansburg. The principal new feature was “winter spraying” with several fungicides. This was for the purpose of determining whether or not it would prove practical to spray with strong solutions while the bushes are dormant. The object was to compare the results obtained from bushes given the winter treatment and sprayed throughout the season, with results from bushes where spraying was begun early, medium early and late; also to compare soda-Bordeaux and cop- per carbonate solutions with potassium sulphide as a preventive of the disease. WINTER TREATMENT. The severe weather of winter and early spring prevented the application of this treatment until April 5, but as the buds re- mained perfectly dormant all that time this date was satisfactory for the test. Each one of the following solutions was applied to a separate row of bushes: Copper sulphate, 1 oz. to 1 gal. water. Potassium sulphide, 1 oz. to 1 gal. water. Tron sulphate, saturated solution, 5 pounds to 1 gal. water, plus 1 per cent of sulphuric acid. 1Soda-Bordeaux mixture.— 1pound copper sulphate, 1-3 pound lye, to 5 gals. water. 1A modification of Dr. Halsted’s formula, as given in Nineteenth Report New Jersey Exp’t Station, p. 336. 328 Report or THE HorvricuLTuRIsTt OF THE Copper carbonate 1 oz., ammonia to dissolve it, 5 gals. water. Copper carbonate 3.2 oz., sodium carbonate 1.6 0oz., ammonia to dissolve them, 5 gals. water. For the remainder of the season these rows were all sprayed with potassium sulphide 1 oz. to 2 gals. water, six applications being given. SUMMER TREATMENT. This part of the work was divided into three series as was the work at Trumansburg. In Series I the work was begun very early, April 18; in Series II medium early, April 28; and in Series ITI late, May 9. Later applications were made May 23, June 5 and 15. The various solutions used were: Pottassium sulphide, 1 oz. to 2 gals. water. ?Soda-Bordeaux,— *soda (lye) 1 pound. Copper sulphate 3 pounds. lime 5 oz. Water 30 gals. ‘Copper carbonate 1 pound, sodium carbonate (sal soda) 4 pound, enough strong ammonia to dissolve the copper carbonate, 50 gals. water. Ammoniacal solution of copper carbonate,— copper carbonate 5 oz., ammonia 8 pints, water 50 gals. Each of these solutions was applied to a separate row in Series 1-11. and: TT. The season was not favorable for the growth of mildew, a small amount appearing on the fruit, but none on the new growth. A very little of the disease was noticed June 15. The bushes made 2 Halsted, B. D. Nineteenth Report New Jersey Experiment Station, p. 336. 3“ Babbitt’s Potash or Lye” was used. 4 This remedy was recommended by Mr. David Allerton and Mr, J. A.

In all tests a check row was left for comparison. In Series I there was one row of each treatment and one check row set aside for the purpose of clipping off the mildewed tips as they appeared. The object was to determine whether or not it would pay to do this extra labor in a commercial plantation. It was necessary to drop this part of the experiment because no mildew appeared on the tips. A fair crop of fruit was marketed green the latter part of June. RESULTS. Table III shows the percentages of mildew from the various tests. Series IV is the part which received winter treatment.

In the results for this one year there was no gain derived from the winter treatment. The soda-Bordeaux and copper carbonate solutions gave slightly better results than potassium sulphide did, but these differences are not great enough to be of any significance. RECOMMENDATION. In Bulletin 133 potassium sulphide, 1 oz. to 2 or 3 gals. water, was recommended as the best remedy. The results of three years show that it is still the best fungicide the Station has thoroughly tested. Spraying should be begun very early just as the buds are breaking and continued at intervals of about ten days. Further testing will be necessary to determine the relative merits of soda-Bordeaux mixture and the copper carbonate solu- tions in comparison with potassium sulphide solutions for check- ing gooseberry mildew. THE NEW YORK APPLE-TREE CANKER.* WENDELL Pappock. SUMMARY. Attention has but recently been called to this canker of apple trees, probably because the injuries were thought to be due en- tirely to sun scald. Experiments extending through two seasons prove that this canker.is caused by attacks of Sphaeropsis malorum Pk. (see p. 355), the fungus that causes the black rot of apple, pear, and quince fruits. The experiments also indicate that this fungus occurs on a number of other plants. This disease is widely distributed in the orchards of the State as well as in those of adjacent States. In many instances it has been very destructive. By way of treatment it is recommended: That the trees be kept in the best growing condition; that cankered limbs be re- moved where practicable; that the trees be sprayed with Bordeaux mixture as recommended on page 343; and that in some instances the trunks and larger limbs be scraped and washed as recom- mended on page 343. CANKER.— WHAT IS IT? The term canker, as applied to plant diseases, has been in use in Europe for a long time, where it is commonly used to desig- nate the injury done to trees by species of Nectria. (See Plate * Reprint of Bulletin No. 163. 332 Report or tHE Horricutturist oF THE XXXITI, fig. 2.) In fact the Nectrias have been associated with such injuries so long that in some instances the word canker has come to be regarded as a specific rather than a general term, but other species of fungi may cause a cankered condition of trees and plants. According to Hartig such wounds may be produced by the action of frost, when they are called frost cankers. In general, then, it may be said that any injury of trees, whereby a portion of the bark is destroyed and the wood laid bare may be classified under the general term, canker. That the term canker, as applied to plant diseases, is new to many of our fruit growers may be due to the fact that the Nectrias are of but little economic importance in the United States. THE NEW YORK APPLE-TREE CANKER.’ — HISTORY. Orchardists have been familiar with this diseased condition of the limbs of the apple tree for years. This is especially true with the Esopus Spitzenberg, where the injury to the limbs, com- monly thought to be due entirely to sun-scald, has been associated with the apparent running out of this favorite apple. Atten- tion was first called to the probability of this injury being caused by a plant disease by M. B. Waite, of the U. 8S. Department of Agriculture, Washington, D. C., in an article’ that was read at the meeting of the Western New York Horticultural Society in 1898 and which appeared a few days later in the Rural New Yorker. Mr. Waite suggested the fungus Schizophyllum commune Fr. as the probable cause of the disease. This article, 1 The name of New York Apple-Tree Canker is proposed for this disease for the purpose of distinguishing the canker produced by the attacks of the fungus Spheropsis malorum, Pk. (see page 355) from cankers that are due to the action of other fungi, as the Pacific Coast Apple-Tree Canker and the Euro- pean Canker. 2Waite. Proceedings Western N. Y. Hort. Soc., 1898, pp. 9, 10.

In the spring of 1898 the Chapin Brothers, of East Bloomfield, N. Y., requested the Experiment Station authorities to investigate the cause of the dying of trees in their orchard. Prof. Beach visited the orchard and saw at once that a canker was the cause of the trouble, the serious nature of which was plainly evident in the numerous dead and dying trees. The writer was detailed to work on the subject, and the history of the investigations, extending through two seasons, is herewith presented. The orchard in question originally consisted of one hundred and twenty-five acres. The trees on thirty of the eighty acres in one part were ruined by the canker and have been taken out, and the trees on one-half of the remaining fifty acres are now of little value. In the other part of the orchard originally consisting of forty-five acres, only about ten acres are left that are of much value. The owners have noticed the disease for the past six or eight years, but it has increased very rapidly in the last three or four years. They have also found that it shows a decided prefer- ence for certain varieties, the Twenty Ounce being the most sus- ceptible; then the Baldwin, Wagener, Greening and King follow in the order named. The Tallman Sweet appears to be practi- cally free from the disease. Trees growing in low land or in any situation where the ground was at all wet, were found to suffer 4 Paddock. Science, 8: 596.

It has been argued by some persons that the trees, now forty years old, have reached the limit of their usefulness and are dying of old age. However, those trees that are free from canker are in a very vigorous condition, and the fact that cankered limbs oceur on much younger trees in widely separated localities and in the best orchards, tends to disprove this theory. Neither can the trouble in this case be attributed to neglect, unless it be in the matter of spraying, since the orchard has received from the begin- ning practically the same culture that is advocated by our best authorities of to-day. Sixteen years ago the orchard was thinned by taking out each alternate diagonal row of trees. The elder Mr. Chapin was one of the first to spray with insecticides, but the all important point, as it now appears, spraying with Bordeaux mixture, has been neglected. An apparent contradiction to this statement is found in an old orchard not a quarter of a mile dis- tant, that has never been sprayed and has been in sod for years, yet there are very few cankered limbs in any of the trees. It may be mentioned, however, that this orchard is located on a different slope of land and on poorer soil. The soil of the Chapin orchard is for the most part deep and rich and has produced a vigorous growth so that now the trees are very large. Severe and unintelligent pruning has also been given as the cause of the presence of canker in this as well as other orchards. While it is admitted that misuse of any kind may favor the development of the canker fungus indirectly, yet the answer to the specific statement is found in the fact that unpruned seed- ling apple trees are found in wood pastures that are badly attacked by the canker fungus. In the preliminary studies of the canker certain large, dark colored spores were found, which were at the time supposed to come from some saprophyte; however, cultures were made from them. Agar plate cultures were also made from the diseased New Yorx AgricunturaL ExrrerrMent Station. 335 bark, by taking small particles from the inner bark with sterile instruments. Two forms of fungi appeared in these cultures more or less constantly, which led to their being separated and transferred to sterilized bean stems in test tubes. Here they grew luxuriantly and soon produced fruit, the one form produc- ing the familiar dark colored spores which were not at that time identified, while in the other the sporophores of Schizophyllum commune Fr. were formed. Inoculations were made with the cultures on June 22 on seed- ing apple trees in the nursery row as follows: Three trees were inoculated with material from cultures of the dark spored fungus, three trees with material from cultures of Schizophyllum com- mune, and three trees were punctured but not inoculated to serve as checks. The inoculations were made by cutting a small open- ing in the bark with a sterilized knife and inserting a small amount of the material from the bean stem cultures between the bark and wood. All of the punctures were covered with filter paper which was kept moist for about thirty-six hours. On the same date two inoculations with each of the two cultures, together with check wounds, were made in the larger limbs of a mature apple tree. These inoculations were not moistened or protected in any way. In two weeks’ time there was an area of discolored bark around each place of inoculation where the unknown fungus had been inserted. The other inoculations as well as the checks showed no signs of growth and the wounds soon healed. As soon as it was known that the one fungus could penetrate living bark under certain conditions more inoculations were made. July 6, six young seedling apple trees in the nursery row and three limbs of a large apple tree were inoculated with the dark spored fungus, six seedling nursery trees and three limbs of a larger tree with Schizophyllum commune, while three seedling nursery trees and three limbs of a large tree were punctured but not inoculated to serve as checks. The inoculations made in the seedling trees were all protected with filter paper as before, but 336 Report or THE Horricuntrurist oF THE those made in the larger tree were unprotected. The dark spored fungus grew at all points of inoculation, while all of the other wounds soon healed. On July 11 an effort was made to imitate the scars that are found in the outer bark that are mentioned on page 339. Small pieces of the outer bark were cut from two small areas on sepa- rate. limbs of a large tree which were inoculated with the dark spored fungus, making twenty-eight inoculations in all. Two similar areas were inoculated with Schizophyllum commune and two areas were prepared but not inoculated to serve as checks. Ten inoculations with the dark spored fungus, two with Schizo- phyllum commune and two check wounds were made by cutting through to the wood as before. All inoculations and check wounds were kept moist with damp filter paper. The dark spored fungus grew at all points of inoculation producing deep wounds or cankers where the incisions were made through to the wood as is shown in Plate XXX, fig. 8. Fig. 1 of the same. plate shows the effect of the inoculations where small pieces of the outer bark were removed. The fungus was unable to penetrate to the cambium and made only small surface wounds, as may be seen in the illus- tration. The pieces of bark have been removed on one side leay- ing scars which resemble those that occur on cankered limbs as in Plate XXX, fig. 2. On the same date, July 11, four inoculations were made with each of the two cultures in the larger limbs of a pear tree and four of each in the larger limbs of a quince tree. The inocula- tions, together with check wounds, were kept moist with damp filter paper az before. The dark spored fungus grew at all points of inoculation on the pear tree, but did not grow on the quince. All of the inoculations with Schizophyllum commune together with check wounds soon healed. These experiments showed conclusively that the dark spored fun- gus can penetrate living apple-tree bark under certain conditions and produce a cankered condition of apple-tree limbs and also indicated that it may produce a diseased condition of pear-tree bark. New York AqricuLturaL Experiment Station. 337 On the other hand it is evident that Schizophyllum commune Fr. cannot penetrate living apple-tree bark and it is quite probable that the same is true of pear-tree bark. The result of the inocu- lations on the quince cannot be regarded as conclusive because of the small number of inoculations made; but numerous inocu- lations made in the spring of 1899 showed that the dark spored fungus can produce a cankered condition of quince limbs when inserted under the bark. The stress of other duties during the growing season prevented any study into the nature of the canker fungus and nothing further was done until fall when cultures of the fungus were shown to Mr. F. ©. Stewart, the Station Botanist. He at once noted a strong resemblance of the dark spores to those of the black rot of the apple, Sphaeropsis malorum Pk., and suggested that it might be that disease. | Mature apples were at once inoculated with material from the test tube cultures that had been obtained from cankered apple-tree limbs. In twenty-four hours decay had be- gun around the points of inoculation and in sixteen days pyc- nidia and mature spores of Sphaeropsis were found on all inocu- lated apples. The check apples which were punctured but not inoculated and kept under the same conditions remained sound. This experiment was repeated many times and the results were always the same. Now that it was known what to look for an examination of eankered limbs in the orchard revealed the presence of an abun- dance of small, dark, fungus pustules or pyenidia on the brown and shrunken areas of dead bark. Fig. 3 of Plate XXVIII is a larger view of the smaller canker shown in Fig 1 at 6. An ex- amination of the bark on the older portion of the cankered area reveals the presence of numerous pycnidia in which the dark col- ored spores, that have been frequently mentioned, are borne. They are shown natural size in Fig. 4, which is a small section of the dead bark from the same canker. It will be seen that the pycnidia are abundant and large enough to be easily found. 22 338 Report or tHe HorvricutTurist OF THE Pyenidia containing mature spores were also found to be abun- dant on the dead bark surrounding the points of inoculation that were made from the cultures of Sphaeropsis. Plate XXX, fig. 3, is from a photograph of one of the limbs of an apple tree as it appeared at the close of the present season, that was inoculated in the spring of 1898 with cultures made from a cankered limb. Pyenidia are numerous on the surface of the bark and on the decorticated wood as well. The result of over fifty inoculations made from cultures that were obtained from cankered appletree limbs prove that the apple-tree canker of New York apple orchards is caused by a fungus of the genus Sphaeropsis. In every instance where the incisions were made through to the wood, typical cankers were produced and mature fruit of the Sphaeropsis formed on the de- - eaying bark and in some instances on the decorticated wood also. The inoculation experiments were repeated many times during the season of 1899 and the results have been the same. GEOGRAPHICAL DISTRIBUTION. A personal examination of a great many orchards during the past two seasons reveals the fact that this canker of apple trees is widely distributed in the orchards of New York. In fact an orchard is rarely seen that is entirely free from the disease. As is to be expected, however, it is more abundant in some localities than in others, and as has been previously mentioned, some varie- ties are more subject to the disease than others. It is specially injurious in many of the apple growing sections of western New York. Responses to a circular letter sent to the authorities of the vari- ous experiment stations, together with personal examinations, bring out the positive information that this canker occurs in Con- necticut, Indiana, Maryland, Michigan, Pennsylvania and Ver- mont, and that it probably occurs in Illinois, Maine, Massachu- setts, Minnesota, New Jersey, West Virginia and portions of Canada. It seems probable that when the disease becomes more New York AGRICULTURAL EXPERIMENT Station. 339 generally known it will be found in many of the apple growing sections of the northern, central, and New England states. APPEARANCE OF CANKERED LIMBS. When one approaches a diseased tree his attention will be attracted to the dark and enlarged sections of the larger limbs. A closer examination shows that the bark is much roughened as well as thickened, and in many instances a portion of the wood is laid bare. The decaying bark and wood offer a convenient lodg- ing place for borers and fungi which aggravate the injury and add to its unsightly appearance. The dead bark on many of the diseased limbs clings tenaciously to the decaying wood, which is a feature that distinguishes this canker from sun scald, since with the latter trouble usually the first symptom to be noticed is the peeling of the bark from the injured surface. The area of bare wood is often small as compared to the extent of swollen bark; limbs are frequently seen that for six feet or more of their length are covered with rough bark. The progress of the disease on such limbs may be marked by numerous pits or scars, show- ing where the fungus was able to live until perchance it gained entrance to the cambium through some injury, when a serious wound was the result. These scars are usually circular in form and may be outlined by two or more concentric lines. An exam- ple of this form of the disease is shown in Fig. 1 of Plate X XIX, where for more than six feet of its length the limb is covered with the rough bark or the scars where the bark has become detached. The fungus has only reached the cambium and formed a canker at a. Fig. 2 of Plate XXX is a larger view of a section of the same limb showing the scars more in detail. Other instances occur, where, though the bark is much swollen and roughened, the fungus has not been able to penetrate to the cambium, but has died after a time leaving the scars of its attack, aside from which the limb has regained its normal condition. The fungus shows a preference for the larger limbs of mature trees. Small limbs and young trees are much less frequently 340 Report or tHe Horricutrurist oF THE attacked, though the trunks and branches of the latter are some- times badly injured, and twigs of the current season’s growth may suffer serious injury from attacks of the fungus. Twenty Ounce apple trees are apparently the exception, since in some localities the trunks of this variety are badly injured. The fungus extends down from diseased branches or from canker spots at the forks of the tree till in aggravated cases large areas of bark are destroyed exposing the wood in ugly wounds. These patches of black, de- caying wood are conspicuous from a distance. Old age and neg- lect, or a lack of vigor from any cause evidently favor the disease though apparently thrifty trees are frequently ruined by its attack. The effect of a canker on a limb depends on the amount of bark that is injured or destroyed. In severe cases the disease may extend entirely around a limb, thus effectually girdling it. Thus it occasionally happens that the leaves on some part of a tree shrivel and die without apparent cause, but a close examination shows the presence of rough, dead bark somewhere on the limb, indicating the presence of the canker fungus which has extended around the limb and cut off the flow of sap. Plates XXVIII and XXIX are reproduced from photographs of typical cankered limbs. In Fig. 1 of Plate XXVIII the character- istic rough bark is shown and at a the wood is exposed, the white fruiting bodies of the fungus, Schizophyllum commune Fr., being conspicuous on the dead bark. At 6b is a canker spot of compara- tively recent formation. Fig. 2 shows the same limb from which the dead bark has been removed; only a narrow strip of live bark remained that kept the limb alive. Fig. 3 is an enlarged view of the more recent canker shown in Fig. 1 at 6. This canker is evidently of three seasons’ growth as is indicated by the three series of concentric lines, now rather indistinct, that at one time separated the dead from the living bark. The extent of the cur- rent season’s growth can be readily distinguished by the smoother appearance, while a distinct line separates the dead from the living bark. . He toate : New York AGricuLtturaL Experiment Station. 341 In some instances cankers occur quite uniformly on the south- west side of the trees, thus indicating that they had their origin in injuries produced by sun scald. The work of the fungus may be recognized by the thick rough bark, while the fruiting pustules reveal its presence where it is still or has recently been in an active condition. EXTENT OF INJURY. The extent of the injury done to the orchards of the State can scarcely be estimated, but it is safe to say that this canker is one of the worst diseases with which the orchardist will have to con- tend since it attacks the tree directly instead of the foliage and fruit as is the case with the majority of our orchard diseases. The appearance of the cankers is such that their injurious nature may not be apparent to the casual observer until his attention is attracted by the shrivelling of the leaves; thus the tree may be ruined before it is realized that anything serious is the matter. In one instance the loss of a large acreage of orchard was due to the attacks of the canker fungus (see page 333) and in a great many orchards it has done serious damage. TIME AND MANNER OF INFECTION. Infection takes place in the spring of the year as is shown by the growth that the fungus makes in the bark. The presence of the fungus in a newly infected limb is first indicated by a small area of discolored bark. This area extends slowly as the fungus grows outward in all directions till mid-summer, when a definite boundary forms between the dead and living bark, thus showing that growth for the season has stopped. This season’s growth had stopped by the first of August, and in some instances pycnidia containing mature spores were found/at that time on bark where infection had taken place in the spring. Many of the spores remain in the pycnidia till the following spring, or longer, when they are given off and disseminated. The mycelium is unable to penetrate to the cambium through living 3492 Report or THe HorricuLrurIst OF THE bark, but those spores that chance to fall and germinate in a wound, produce the cankers. Other spores are deposited on limbs that have an abundance of dead and decaying outer bark where they find conditions suitable for growth. In such instances no direct injury is done to the tree, but spores are produced and dis- seminated so that a constant source of infection is maintained. The spores possess great vitality since some of them germinate after having been kept a year in the laboratory. In some instances the mycelium apparently lives over winter and continues its growth the following spring. The formation of the largest cankers can scarcely be explained in any other way. However, in all of the inoculations made in the spring of 1898, in only one instance did the resulting canker enlarge any during the present season. See Plate XXX, fig. 3. DOES THE MYCELIUM PENETRATE THE woop 4 This qnestion is suggested by the presence of two or more cankers on the same limb, the external appearance of the more recent ones suggesting the possibility of the fungus having passed from the old canker through the wood and appearing on the sur- face of the limb at favorable points where the newer cankers were formed. An examination of a number of specimens and the occurrence of pycnidia on decorticated wood shows that while the mycelium does penetrate the wood to some extent, the fact is of little economic importance. One limb was examined that had five small cankers on it at intervals of about a foot. On split- ting the limb it was found that the mycelium had penetrated the wood at but one point and that for only a short distance. PREVENTIVE MEASURES. Although experiments in treating this disease are under way uo results have yet been reached and from the nature of the fungus it will be seen that a number of years must elapse before data New York AGricutturaL ExXprERIMENT STATION. 343 can be secured from which definite conclusions may be drawn. However it is a matter of common observation that in the major- ity of instances the disease is not nearly as prevalent in orchards that have been well sprayed with Bordeaux mixture for several years past as it is in those that have not been sprayed. Judging from the success with which many other plant diseases are com- bated it is reasonable to expect beneficial results to follow sys- tematic spraying with Bordeaux mixture as a preventive of the canker. In localities where canker is abundant special attention should be paid to the sanitary condition of the trees. Perhaps one of the most important considerations is to see that the trees are not crowded and that they are pruned so as to admit sunshine and a free circulation of air. The old bark is not shed as freely from the limbs and trunks of trees that are densely shaded and the moisture collecting in this bark is not easily dried out; thus faculative parasites like the canker fungus as well as saprophytic fungi find congenial surroundings. The practice of scraping and whitewashing the trunks and branches of fruit trees has largely fallen into disfavor, but it is certainly a commendable practice and should be adopted in loeali- ties where canker is severe. However, washes that are less con- spicuous and equally, if not more effective, than whitewash are now recommended ; the following formula has been satisfactory to some orchardists: WASH For TreE TRUNKS.

Dissolve the soap in hot water, then stir in the lime. When the ingredients have been reduced to a smooth state by stirring dilute with water to four gallons, then stir in wood ashes till the wash is of the desired consistency. Other formule equally as good as the one given are in use, but 344 Rerort or tHe Horricutturist oF THE the important ingredients in most of them are the same as in the one given above. These washes probably have the effect of softening and loosen- ing the old bark so that it is more readily shed, thus relieving the bark bound condition and inducing a vigorous growth. Bordeaux mixture is beneficial in this respect as a smooth, shiny appear- ance of the bark is a characteristic of well sprayed trees. A discussion of the necessity of thorough cultivation and fer- tilization of orchards need not be entered into here, but it may be said that any treatment that tends to promote the vigor of the trees indirectly gives them greater power to resist disease. This fact was strikingly illustrated in the inoculation experiments with nursery stock where it was found that the trees that were making a feeble growth were far more susceptible to the action of the fungus than those which were making a vigorous growth. Usually but little attention is given to slight wounds that are made here and there on the trees, but it should be remembered that a majority of cankers start from some mechanical injury. Too much care cannot be exercised not to wound or bruise the limbs when trimming the trees or picking the fruit. Wounds are fre-_ quently made by the chafing of ladders against the limbs or by the workman’s boot when climbing through the trees. Serious wounds are also frequently made by propping the limbs when they are cverloaded with fruit. The props should be padded or have the corners rounded where they come in contact with the limbs; they should be put in place carefully and not be driven under the limbs as is sometimes done. All wounds, whether ac- cidental or made in trimming, should be protected with thick paint or grafting wax. Cankered limbs should be cut out wherever practicable, or in some cases it may pay to cut off the diseased bark and cover the wounds as recommended above. Then as a preventive measure we feel warranted in recommending thorough spraying with Bor- deaux mixture, giving the first treatment before the leaf-buds New York AGRICULTURAL EXPERIMENT STaTIon. 345 open in the spring, followed by the three sprayings that are usu- ally given the trees for apple scab. Great pains should be taken to see that the limbs are thoroughly protected with the mixture as well as the foliage and fruit. The approximate dates of spraying may be given as follows: 1. About the time the leaf-buds begin to open. 2. About a week before the blossom-buds open. 3. As soon as all of the blossoms have fallen. 4. Ten days or two weeks after No. 3. INVESTIGATIONS IN 1899. It was originally planned that this season’s work should be a verification of the previous year’s results, namely, the identifica- tion of the canker fungus and the determination of its relation to what was thought to be the same species that occurs on pear and quince trees and on the fruit of all three species of trees. But the work broadened as Sphaeropses were found on a variety of hosts representing seven orders of plants. Since a knowledge of the host plants of any plant disease is of great. practical value in order that it may be successfully com- bated, an attempt was made to determine the relation of the species of Sphaeropsis, represented by the different hosts, to the canker fungus. In the spring of 1898 specimens of blighted apple-tree twigs were received from Odessa, N. Y. It was not determined at the time what was the cause of the blight, but a subsequent examina- tion revealed the presence of numerous pycnidia containing mature spores of a Sphaeropsis. On visiting the orchard late in the fall, it was found that the twig blight had been quite notice- able in 1897, but there was none to be found on the current sea- son’s growth. In all cases noticed, when once attacked, the entire growth of the season had been killed and in a few instances the disease had extended into the previous season’s growth. There were a few miniature canker spots on the smaller limbs but none were noticed on the larger branches and the trees were in fairly vigorous condition. 346 Report oF THE HorTICcULTURIST OF THE Some pear trees growing in a door-yard about twenty-five rods distant from the orchard were pointed out as being in a dying condition, the top of one tree having been entirely destroyed while the other trees were half or two-thirds dead. The pyenidia of a Sphaeropsis were found to be very abundant on the dead bark, while a few black, shriveled pears that were still attached to the branches were attacked by the black rot fungus, Sphaeropsis malorum Pk. A Sphaeropsis was also found on the twigs of a quince tree that. grew by the side of the pear tree. At a later date a canker was found on a quince tree in the Sta- tion orchards. The appearance of the cankers and their effect on the limbs was much the same as the canker of apple tree limbs, the swollen sections of limbs and the roughened bark at once attracting attention. The pycnidia of a Sphaeropsis were abun- dant on the dead bark where the fungus had recently been in an active condition. This fungus was also found to be abundant in the large quince orchard of Maxwell Brothers, near Geneva. There were but few typical cankers on these trees, but in many in- stances there was a well defined longitudinal strip of dead bark on the limbs on which pyenidia of a Sphaeropsis were abundant. It seems probable, however, that in such instances, as well as with the pear trees mentioned above, the fungus was following, but ageravating, former injuries. Dilution plate cultures were made of the Sphaeropses from the twigs of the three different host plants and after the fungus had fruited, fruits of the apple, pear and quince were inoculated with pure cultures of the fungus from each of the three hosts. The fruits were kept in closed glass jars, the check fruits punc- tured but not inoculated occupying jars by themselves. Black rot, Sphaecropsis malorum Pk., was produced in each inoculated fruit while the checks remained sound. Usually there would be an area of decayed tissue around the points of inoculation in twenty-four hours, depending on the degree of ripeness of the New York AGrRicuLTURAL ExpERIMENT Station. 347 fruit. The decay progresses rapidly in the ripe fruit; in some instances the greater portion of the surface became brown, and mature spores of the fungus were formed in six days. In the spring of 1899 a Sphaeropsis was found on dead and dying Japanese plum trees at Riverhead, N. Y. Cultures were made of the fungus, and apple, pear, and quince fruits were inoculated. Black rot was again produced in the inoculated fruit while the check fruits remained sound. These results led to an investigation of the local distribution of the genus Sphaeropsis, when it was found to be widely distributed ; as the list of host plants given in Tables I and II will show. Cultures were made of the Sphaeropses from each host and apple, pear, and quince fruits were inoculated with cultures from each so far as the supply of fruit would permit. Three fruits at least, and in a majority of instances six, were inoculated with cultures from each host. Black rot was readily produced in the fruits, there being apparently no difference in the effect of the Sphaeropses as obtained from the different hosts. The inoculated fruits as well as the checks were kept in closed glass pars, as before. During the progress of the work it was noticed that in most eases there was but little difference in the average size of the spores as they occurred on the different hosts. It was also found that when apple, pear, or quince fruits were inoculated with cultures of Sphaeropsis from these hosts the resulting spores were larger and of the size of those found on fruits attacked by black rot. The series of spore measurements given in the table below was made to show the relation of the average size of the spores to the host on which they are grown. Since spores of Sphaeropsis as they occur on any host vary greatly in size, even in the same pycnidium, an average of fifty measurements was taken in each instance. Table I gives: (1) A list of hosts from which cultures of Sphaeropsis were made; (2) average length of 50 spores as they occur on the hosts; (3) average length of 50 spores as they occur 348 Report oF THE Horticulturist OF THE on apple, pear, and quince fruits when inoculated with cultures of Sphaeropsis from the different hosts.

However it may be pointed out that the inocn- lation experiments prove that the species occurring on apple-tree bark, S. mali, and on decorticated apple-tree wood, 8. cinerea, are the same; also that these species are identical with the black rot fungus, S. malorum. Thus it will be seen that some interesting questions in nomenclature are involved. Which of these names should stand, if either, or whether they will all prove to be synonyms can only be determined after a careful study of the entire genus is made. In former papers by the writer referred to on page 333 mention was made of the fungus, Sphaeropsis malorum Pk., as being the probable cause of the New York apple-tree canker. It is there- fore suggested that this name be retained for the present in order that still further confusion in nomenclature may be avoided. BODY BLIGHT OF PEAR TREES. In the spring of 1898 when the preliminary studies ‘with apple canker were begun a few inoculations were made in the larger 356 Report oF THE HorvTicuLTuRISsT OF THE limbs of a pear tree with cultures of Sphaeropsis obtained from eankered apple-tree limbs. The details of the experiment are given on page 3386. The fungus grew readily at all points of in- oculation and though the culture material was inserted between the bark and wood it did not attack the cambium layer, but made its growth in the outer bark. Here dead sunken areas were pro- duced similar to those that are so common on the trunks and © larger limbs of pear trees. These definitely outlined and sunken areas of dead bark commonly known as body blight, have long been thought to be due to the action of the pear blight bacillus; however, there seems to be no definite reason for such belief. But little attention was given the matter at the time since it was not then known that Sphaeropsis occurred on these blighted areas. In the spring of the present year, however, a Sphaeropsis was found to be comparatively abundant on the diseased bark of pear trees in the Station orchards. Since that time a large number of pear trees from many localities affected with body blight have been examined and in nearly every instance a Sphaeropsis was present though not in sufficient quantity to account for many of the blighted areas. Macrophoma malorum (Berk.) Berl. et Vogl. is commonly present in large quantities on the dead bark and since Sphaeropsis is able to produce body blight may not this closely related fungus be an important factor in producing the diseased condition ? Fifty successful inoculations made this spring with cultures of . Sphaeropsis in mature pear trees confirm last year’s results. An attempt was also made to grow the Macrophoma artificially, but it made an indifferent growth on all of the media that were tried and produced no fruit, consequently inoculation experiments with this fungus could not be undertaken at that time. THE PACIFIC COAST APPLE-TREE CANKER. After the publication of the paper, An Apple Canker, the writer received inquiries concerning the canker from the secretaries of PLATE XXVIII. + Led OV GO! D,ea°G bre New York AGricuLtTurRAL ExprErRIMENT STATION. 357 horticulture respectively of Oregon, Washington and British Columbia. These gentlemen sent specimens of diseased limbs which upon examination were found to be attacked by an entirely different fungus from the one that causes the New York canker, the spores were small, curved and hyaline while the spores of Sphaeropsis are large, oval and dark brown in color. A liberal number of specimens were received from each of the three sec- tions and the fungus was the same in each case and so much in evidence that there can be little doubt but that it is the cause of the Pacific coast canker. Some of the specimens were submitted to Prof. C. H. Peck, State botanist, who pronounced the fungus to be a new species of Macrophoma. This disease because of its destructive nature has attracted a great deal of attention for a number of years in the Pacific Coast States, but no satisfactory method of combating it has yet been found. Since entirely dif- ferent climatic conditions obtain in that part of the country it is not likely that the line of treatment recommended for combating the New York apple canker will be effective against this disease as it occurs on the Pacific coast. Fig. 1 of Plate XX XIII is from a photograph of an apple-tree limb showing a typical specimen of the Pacific coast apple-tree canker. THE EUROPEAN CANKER. Fig. 2 of Plate XX XIII shows a canker on a quince tree limb which was produced by the fungus, Nectria cinnabarina (Tode.) Fr. This shows what is known as the tubercularial or conidial stage of the fungus; what appear as small white bodies in the picture scattered over the surface of the dead bark, are brilliant red or cinnabar colored stromata which bear the conidia or fruit- ing bodies of one stage in the life history of the fungus. It will be seen that the comparatively large size and brilliant color of the stromata render the fungus conspicuous so that it is not easily mistaken. 3858 Report or THE HorricuLruristT OF THE Another species, N. ditissima, is the common canker-producing fungus of the orchard trees in many parts of Europe. Neither of the species is sufficiently abundant in the orchards of the United - States to be regarded as a pest. The illustration in Plate XX XIII, fig. 2, is from a photograph of one of a few quince tree limbs attacked by NV. cinnabarina that were found in the quince orchard of T. C.

In Bulletin 157 were recorded the results of several seasons’ work in testing the self-fertility of the grape. Lists were given of grapes which were perfectly self-fertile, partially self-fertile or self-sterile and completely self-sterile. Many of our cultivated American grapes belong in the last two classes and require cross pollination for formation of perfect bunches. The work of 1899 has been devoted to a study of the question whether some grapes are better than others for fertilizing the self-sterile kinds. Prevention of accidental cross-pollination was secured by en- closing in paper bags the selected bud clusters of both the variety to be pollinated and that furnishing the pollen. Cross-pollina- tion was effected by removing the pollinating cluster, when in blossom, from the parent vine and enclosing it with the cluster to be fertilized. The clusters were sometimes brushed together be- fore enclosing, sometimes simply enclosed in the paper sacks and shaken, to distribute the pollen. ‘ Twelve nearly or quite self-sterile varieties were treated with pollen from one or more of twenty-four varieties ranging from perfectly self-fertile to self-sterile. The results are given in the body of the bulletin, both in detail and summarized. The use of self-sterile varieties as pollinizers for other self-sterile varieties resulted in failure. Self-sterile varieties fertilized with varieties not strongly self-fertile produced clusters varying in compactness about as did the bunches of the pollinating variety. Self-fertile sorts, with rare exceptions, gave good results when used as fertil- * Reprint of Bulletin No. 169. 362 REPORT OF THE HorricuLTURIST OF THE izers for either partially self-sterile or completely self-sterile varieties. From study of the effect of pollen from different vari- eties upon the same self-sterile variety, it seems probable that failure to set fruit may be due to several causes, such as dropping off of blossom buds before they open or poor condition of the vine; but the most common cause is imperfect pollinati®n due to im- potent pollen. Lists are given of varieties, both strongly self-fertile and im- perfectly self-fertile or self-sterile, which blossom. very early, medium early, in mid-season, medium late, late and very late. INTRODUCTION. In Bulletin 157 the writer presented a complete account, to that date, of the investigations on the self-fertility of the grape with which he had been engaged for several years.’ It was therein shown that many of the cultivated varieties of American grapes are either self-sterile or very imperfectly self-fertile. Such kinds, when they are self-pollinated only, either bear no fruit or produce more or less imperfectly filled clusters. In discussing the practi- cal bearing of these discoveries upon the selection of varieties and arranging them in vineyards so as to get the best results in fruit production, attention was called to the fact that self-sterile varieties may produce well filled clusters of fruit when the vines are Jocated near enough to other kinds to make eross-fertilization possible. For this reason the general recommendation was made that whenever the self-sterile or the imperfectly self-fertile kinds are planted it would be well to put near them some other kind which blooms at the same time. After Bulletin 157 was issued there came from several sources requests for more definite information congerning the mingling of varieties so as to provide for the proper fertilization of those kinds which cannot produce well filled fruit clusters unless they are 1 Beach, S. A. Self-fertility of the Grape. N. Y. Agr. Exp. Sta. Bul. 157. Dec., 1898. New York AGRICULTURAL EXPERIMENT STATION. 363 cross-fertilized. This brought up the question whether some grapes are better than others for fertilizing the self-sterile kinds or whether any variety other than the one to be fertilized will answer the purpose if it blooms at the same time. Similar questions, in one form or another, are apt to arise wherever American grapes are cultivated. Scarcely any definite information on this subject could be found. Being a subject of considerable practical importance to viticulturists, arrangements were made to begin the investigation of it in 1899. The results of the first season’s work in this line are set forth in the following preliminary report of the investiga- tion. WORK FOR 1899. PLAN. Twelve varieties which were selected because they are nearly or quite self-sterile, were artificially cross-pollinated in the manner hereafter described. Twenty-four kinds of grapes were tried as fertilizers for these varieties. Most of them were self-sterile or nearly so, others fully self-fertile, and still others intermediate between these two extremes. The twelve varieties which were ar- tificially cross-pollinated were not emasculated. For the purpose of preventing accidental cross-pollination by means of insects or otherwise, the clusters to be tested were enclosed in paper bags before the blossoms opened, and were kept thus covered during the entire blooming season except the few minutes when the bags were opened to introduce the clusters which furnished the pollen for the test. The clusters which were selected to furnish the pol- len were likewise covered before they came into blossom and were kept covered, even after they were removed from the vine which bore them, until they were applied to the self-sterile variety upon which their pollen was to be tried. The bagging of the clusters was done after the manner illustrated and described in Bulletin 157. By thus protecting all of the blossoms which were used in 364 Report or tue Horricutrurist oF THE the tests, the chances of accidental cross-pollination were reduced to a minimum. After the blossoming season had passed, a record was made to show which clusters had set fruit and which had failed to set fruit. When the fruit was ripe each cluster under test was rated on the scale of 100, according to the percentage of a full cluster which was found. A perfectly formed cluster was rated 100, a half- filled cluster was rated 50 and others were rated in a correspond- ing manner. LOCATION OF THE VINEYARDS. The tests were conducted in 1899 in three quite widely sepa- rated localities: In the Station vineyards at Geneva; in the vine- yards of E. Smith & Sons at Highlands, on the east bank of Seneca lake, near Lodi; in the vineyard of Mr. E. C. Gillett, Penn Yan, N. Y. Our acknowledgments are due the gentlemen who have consented to allow the experiments to be conducted in their vineyards, and also to Mr. Horace W. Gillett who assisted in the work at Penn Yan in a very careful and satisfactory manner. — The Highlands vineyards are on soil which is derived largely from broken shale. The other vineyards mentioned above are on clay loam. CROSS-POLLINATION. The cross-pollinating was done at Highlands, June 12. At Penn Yan it was done June 12, with the exception that Brighton and Salem were crossed each upon the other June 13. At the Station the work of cross-pollinating was done at convenient times during the blooming period from June 10 to 15. The cross-pollinating which was done at Highlands was under the direction of C. P. Close. The plan there followed was to un- cover the cluster which was to receive the pollen. The cluster selected to supply the pollen was then taken from the bag in which it had till this time been kept, and fastened to the first men- tioned cluster. Both clusters were then covered with the bag New York AGRICULTURAL EXPERIMENT Station. 365 which had held the cluster which furnished the pollen. After the bag had been closed and labeled, it was shaken so as to agitate the loose pollen which it might contain and possibly assist in more thoroughly distributing it among the open flowers of the cluster which was to be pollinated. In the Penn Yan tests and in those at the Station, in addition to the treatment above outlined, the open flowers of the cluster which were selected to supply the pollen were brushed over the open flowers which were to be cross-pollinated before fastening the two clusters together. With most varieties the interlocking of the branches of the two clusters was sufficient to hold the loose cluster in place, but in some instances it was necessary to tie the two to- gether. Judging from their appearance when the bags were opened after the blooming season had passed, the flowers of the detached clusters which were not open when the bag was finally closed and labeled, generally failed to open later. It appears, therefore, that the pollen which effected the fertilization of the flowers as shown by the later development of fruit, must have come almost entirely from blossoms which were open when the hand pollinating was done. With some of the varieties which were arti- ficially cross-pollinated after the manner above described, a con- siderable portion of the flowers were not opened when the hand pollination was done, and probably did not open for a period of from 24 to 48 hours thereafter. Had the bags been reopened on each of the two days following the one upon which the hand pol- linating was done, and the clusters brushed again with freshly opened blossoms, the result might have given a more accurate in- dication of the kind of clusters which such varieties may be ex- pected to produce when they stand adjacent to each other, and the process of cross-pollination goes on freely during the entire bloom- ing season. On the other hand it should be observed in this connection that, even with varieties which had not come into full bloom when the hand pollinating was done, some perfectly filled clusters were obtained, showing that the percentage of blossoms which became 366 Report or tue Horricutrurist oF THE cross-pollinated was, under the circumstances, remarkably large. Take, for example, the results with Brighton fertilized by Ca- tawba. Both at Highlands and Penn Yan these varieties had a large percentage of unopened blossoms when the Catawba clusters were applied to the Brighton. Eight Brighton clusters at High- land were thus supplied with Catawba pollen and all of them set fruit. When the fruit was ripe one cluster ranked 95, one 90, one 85. ‘The two lowest were rated 55 and the average rating was 74.4. At Penn Yan five Brighton clusters were likewise supplied with Catawba pollen. One cluster so treated ripened but four fruits, one was almost perfectly filled and the remaining three were well filled. Omitting the first named cluster, the average rating was 97.5; including it the average was 80. While, as has been said before, these averages cannot be taken as indicating with strict accuracy the efficiency of Catawba as a fertilizer for the Brighton, they show that, even under the most unfavorable conditions which obtained in these trials, a surprisingly large pro- portion of the blossoms became cross-pollinated. In all cases where the number of clusters under experiment is large enough to give some indication of the value of the variety as a fertilizer for self-sterile sorts the results with the different varieties may be looked upon as comparable, because the treatment was similar in all the tests with the exception that in the Highlands vineyard the clusters to be cross-pollinated were not brushed with the clus- ter selected for furnishing the pollen, but the two kinds of clusters were simply inclosed in the bag and shaken together. COVERING THE CLUSTERS. As has already been stated, all of the clusters which were used in these experiments were covered before the blossoms opened, using paper bags for this purpose after the manner described in Bulletin 157. This work was largely done before the varieties commenced to bloom. The clusters in the Highlands tests were bagged June 7 and 8; with few exceptions those at Penn Yan were bagged June 9; and those at the Station were bagged at various New Yorx AGRICULTURAL EXPERIMENT Station. 367 times from June 5 to June 10. Ina few cases the variety had be- gun to bloom before this work was done. Great care was then taken that no cluster with an open blossom should be bagged. THE BLOOMING PERIOD. At Highlands the following observations on the blooming vari- eties were made in forenoon of May 8: Aminia — Beginning to bloom. Brighton — None in bloom; probably will not begin to bloom before June 12. Catawba — Ditto. Niagara — Not many blossoms open. Worden — Nearly half in bloom. Wyoming — First blossoms opening. ) On Monday, June 12, when the cross-pollinating was done, Aminia was in some cases nearly out of bloom. Brighton was hardly enough advanced in bloom to furnish an abundant supply of pollen. With these exceptions no difficulty in finding clusters in good condition for the cross-pollinating was noted. At Penn Yan the following notes on the condition of bloom were made when the cross-pollinating was done June 12: Brighton — Many clusters have no open blossoms, but the majority of clusters have at least begun to bloom. Catawba — About the same stage of advancement as Brighton. Eldorado — Nearly in full bloom. Herbert — Past full bloom and going out of bloom. Lindley — Most clusters are coming into bloom; a few have not yet begun to bloom. Merrimack — Nearly in full bloom. Salem — Past full bloom and going out of bloom. Niagara — Nearly in full bloom. Worden — Nearly in full bloom. 368 Report or THe Horricuttrurist oF THE The period of bloom in 1899 of the varieties which were under test at the Station is shown in the following table.

First, soon after the vines had gone out of bloom a record was made of New York AGRICULTURAL EXPERIMENT STATION. 369 the clusters which failed to set fruit. It is best to make such rec- ords early in the season because late in the season it may be im- possible to decide whether the absence of a cluster means that it failed to set fruit or that the cluster was accidentally broken off. After the fruit ripened each cluster was rated on the scale of 100 according to the percentage of a full cluster of fruit which was found, as has already been stated under “ Plan of Work.” The detailed records are here given for each variety together with the records which the same variety has made in previous years when tested as to its self-fertility. Unless otherwise stated the tests here reported were made in 1899. The results are summarized and presented graphically on the pages following the discussion of the separate varieties. AMINIA. Amma self-pollinated.— In 1892, 2 clusters of Aminia which were kept covered during blooming season gave no fruit; in 1898, 9 clusters which were likewise tested gave no fruit. In 1899, 6 clusters of Aminia at Highlands were hand-pollinated* with Aminia pollen brought from the Station, but no fruit set; 10 clus- ters which were kept covered during the blooming season were rated 0, 0, 0, 0, 0, 0, 0, 0, 0, 12 respectively. Average rating 1.2. So far as tested Aminia is practically self-sterile. Aminia pollinated with Brighton.—Six clusters tested at High- lands were rated respectively 0, 0, 0, 0, 0, 10. Average rating 1.7. Amina pollinated with Wyoming.— Five clusters tested at Highlands were rated respectively 0, 0, 0, 0, 20. Average rat- ing 4. ®Aminia pollinated with Niagara.— One cluster tested at High- lands rated 80. 2By “hand pollinating,” is here meant brushing the clusters with the open flowers from another vine of the same kind, and then inclosing the pollinated cluster together with the cluster which furnished the pollen in a bag accord- ing to the method followed in the 1899 experiments in cross-pollinating, as de- scribed on a preceding page. 24 370 Report or tHe Horricunrurist OF THE Aminia pollinated with Worden.— Two clusters tested at High- lands were rated respectively 88, 88. Average rating 88. Aminia pollinated with Catawba.— Four clusters tested at Highlands were rated respectively 88, 88, 90, 90. Average rat- ing 89. Aminia as a fertilizer.— The records of the tests of Aminia pollen upon Brighton and Wyoming are given under the discussion of these varieties. (See Index for pages.) BARRY. Barry self-pollinated.— In 1892, 2 clusters of Barry which ° were kept covered during the blooming season gave no fruit. Ten clusters in 1895 and 8 clusters in 1898 which were likewise coy- ered gave no fruit. So far as tested Barry has proved completely self-sterile. Barry pollinated with Black Hagle.— Five clusters tested at the Station gave no fruit. Barry pollinated with Hercules.— Five clusters tested at the Station gave no fruit. The vine on which these tests with the pollen of Black Eagle and Hereules were made stands in a mixed vineyard. The un- covered clusters were well formed and the yield abundant. BLACK EAGLE. Black Eagle self-pollinated.— In 1892, 2 clusters of Black Eagle which avere kept covered during the blooming season gave no fruit; 10 clusters likewise covered in 1895 gave no fruit. So far as tested Black Eagle *s completely self-sterile. Standing in a mixed vineyard it has produced some well-formed clusters, but often the clusters are imperfeetly filled. Black Eagle pollinated with Brighton.— Four clusters tested at the Station gave no fruit. Shi, Black Eagle pollinated with Worden.— One cluster tested gave no fruit. New Yorx AGricutTurRAL ExpertMent Station. 371 Black Eagle as a fertilizer— The records of the test of Black Eagle pollen upon Barry are given under the latter variety. BRIGHTON. Brighton self-pollinated.— In 1892, 9 clusters of Brighton which were kept covered during the blooming season gave no fruit; 5 clusters at the Station in 1895, 27 clusters at the Station in 1897 and 9 clusters at Penn Yan in 1899 likewise covered gave no fruit. In another vineyard, of 25 clusters covered in 1897 24 clusters were rated 0, 1 cluster’rated 10. Average rating 0.4. In still another locality 5 clusters likewise tested in 1897 were rated respectively 0, 0, 10, 10,10. Average rating 6. At High- lands in 1899, of 28 clusters which were tested, 26 clusters were rated 0, 1 cluster rated 1 and 2 clusters rated 4. Average rating 0.2. At Penn Yan 5 clusters were hand-pollinated® with Brighton pollen from another vine. Four of these rated 0 and 1 rated 4. Average rating 0.8. At Highlands 10 clusters were likewise pol- linated with Brighton pollen from a Station vineyard. Six of these were rated 0, 3 rated 2 and 1 rated 15. Average rating 2.1. From tlicse tests it appears that Brighton clusters when self-pol- linated rarely set any fruit and the variety may be called prac- tically self-sterile. Brighton pollinated with Creveling.— Seven clusters tested at Highlands gave no fruit. Brighton pollinated with Salem.— Four clusters tested at Penn Yan gave no fruit. Brighton pollinated with Aminia.— Six of the seven clusters tested at Highlands were rated 0 and 1 rated 2. Average rat- ing 0.3. Brighton pollinated with Wyoming.— Six clusters were tested at Highlands; 5 clusters gave a rating of 0 and 1 gave a rating 2. Average rating 0.3. 3 See foot note 2, page 340. 372 Report or tHe HorricuLtrurist oF THE Brighton pollinated with Lindley.— Four of the five clusters tested at Penn Yan were rated 0 and 1 rated 10. Average rat- ing 2. Brighton pollinated with Eldorado.— Four clusters tested at Penn Yan were rated respectively 0, 0, 6,15. Average rating 5.2. Brighton pollinated with Station 146* — Four clusters tested at Penn Yan were rated respectively 0, 0, 25, 60. Average rating 21.3. Brighton pollinated with Station 156*— Four clusters tested at Penn Yan were rated respectively 4, 85, 88, 100. Average rating 69.3. Brighton pollinated with Merrimack.— Four clusters tested at Penn Yan were rated respectively 0, 0, 0, 100. Average rating 25. Since Merrimack is self-sterile, and because in the other tests it uniformly failed to fertilize self-sterile sorts, and because in these tests on Brighton it failed to fertilize three of the four clusters upon which it was tried, while the fourth cluster was rated 100, it is desirable that these tests be repeated before definite conclu- sions are drawn. Similar results, however, were obtained by pol- linating Brighton with Herbert, and Herbert like Merrimack is self-sterile. Brighton pollinated with Herbert.— Four clusters tested at Penn Yan were rated respectively 0, 12, 25, 75. Average rat- ing 28. Compare this record with results given in the preceding paragraph. Brighton pollinated with Nectar.— Five clusters tested at Penn Yan were rated respectively 0, 20, 50, 50, 75. Average > rating 40. Brighton pollinated with Vergennes.— Seven clusters tested at Highlands were rated respectively 2, 40, 60, 75, 100, 100. Aver- age rating 53.9. One of the perfect clusters was an unusually 4Station 146 and Station 156 are male hybrids of Vitis labrusca L., by Vitis bicolor, Le Co te. They wére produced by crossing a wild male bicolor upon the Winchell. New York AericuLturaAL Experiment Sration. 373 large, double, perfectly filled cluster. The other perfect cluster was also a very fine one. ) Brighton pollinated with Jefferson.— Five clusters tested at Penn Yan were rated respectively 0, 25, 40, 60, 95, 100. Aver- age rating 64. Brighton pollinated with Rochester.— Five clusters tested at Penn Yan were rated respectively 0, 85, 85, 90, 100. Average rating 72. Brighton pollinated with Catawba.— Eight clusters tested at Highlands were rated respectively 55, 55, 60, 75, 80, 85, 90, 95. Average rating 74.4. At Penn Yan five clusters of Brighton pollinated with Catawba were rated 10, 90, 100, 100, 100, respectively. Average rating 80. As stated on a previous page, many of the blossoms of these two varieties had not yet opened when the hand pollinating was done. Brighton pollinated with Worden.— Eight clusters tested at Highlands were rated respectively 50, 75, 78, 80, 80, 83, 85, 85. Average rating 77. Four clusters tested at Penn Yan were rated respectively 4, 100, 100, 100. Average rating 76. Brighton pollinated with Niagara.— Nine clusters tested at Highlands were rated respectively 75, 80, 88, 88, 88, 88, 88, 88, 88. Average rating 85.7. Five clusters tested at Penn Yan were rated respectively 2, 10, 60, 88,100. Average rating 52.5. Brighton pollinated with Station 125°. Five clusters tested at Penn Yan were rated respectively 50, 100, 100, 100, 100. Aver- age rating 90. Brighton as a fertilizer— Tests of Brighton as a fertilizer for self-sterile varieties were made with several self-sterile kinds of grapes. The results are given in detail under Aminia, Black Eagle, Eldorado, Herbert, Hercules, Lindley, Merrimack, Salem and Wyoming. (See Index for pages. ) 5 Station 125 is a white seedling of Winchell fertilized by Diamond. It is perfectly self-fertile. 374 Rerort or tHE HorricuLrurist oF THE CATAWBA. Catawba self-pollinated—In 1894, 12 clusters of Catawba which were kept covered during the blooming season, were, with — one exception, nearly perfectly filled, averaging about 90. At Penn Yan 16 clusters which were likewise tested in 1897 were rated 50, 70, 70, 70, 70, 80, 80, 90, 90, 90, 90, 90, 90, 90, 90, 100, respectively. Average rating 81.9. At Branchport in 1897, of 22 clusters which were likewise tested, 1 was rated 70, 9 rated 80 and 12 rated 90, respectively, averaging 85. In 1899, of 42 clusters likewise tested at Highlands, 4 rated 80, 1 rated 83, 3 rated 85, 11 rated 88, 11 rated 90, 2 rated 93, 4 rated 95, 1 rated 97, 2 rated 98 and 3 rated 100, respectively, averaging 89.9. Twenty-four clusters were tested at Penn Yan, of which 5 were rated 0, 75, 75, 78 and 80, respectively, 5 rated 88, 6 rated 90, 7 rated 95 and 1 rated 98, averaging 85.5. Seventeen clusters which were tested at the Station were rated 50, 75, 80, 83, 85, 88, 88, 90, 90, 90, 90, 90, 90, 90, 95, 95, 95, respectively, averaging 86.1. Taking all these tests into consideration it appears that Ca- tawba is strongly self-fertile and when self-pollinated generally forms well-filled clusters of fruit. Catawba as a fertilizer.— Several tests were made with Ca- tawba as a fertilizer for self-sterile varieties. The results are given in detail under Aminia, Brighton, Eldorado, Herbert, Lind- levy, Merrimack, Salem and Wyoming. COLUMBIAN IMPERIAL. Columbian Imperial self-pollinated.— In 1897, 8 clusters of Golumbian Imperial which were kept covered during the bloom- ing season, were rated 90, 90, 90, 100, 100, 100, 100, 100, re- spectively, averaging 96.3. It appears to be fully self-fertile. Columbian Imperial as a fertilizer.— It was used as a fertilizer for Hercules. See page 378. CREVELING. Creveling self-pollinated— In 1894, 5 clusters of Creveling were kept covered during the blooming season, none of which New York AGRICULTURAL EXPERIMENT STATION. 375 gave any fruit. In 1895, 5 clusters, aud 1897, 5 clusters, which were likewise tested, gave no fruit. From these tests it appears that Creveling is absolutely self-sterile. Creveling as a fertilizer— It was tried as a fertilizer for Brighton, but no fruit was produced. See page 372. It is interesting to note in this connection that, although Crevel- ing failed to fertilize Brighton, the parentage of Mills is given as a Muscat Hamburg fertilized with Creveling. EATON. Eaton self-pollmmated.— In 1894, 10 clusters which were kept covered during the blooming season gave no fruit. From the fact that the vine which was used for this test proved to be neither in a vigorous nor in a productive condition these results were not looked upon as conclusive. In 1899, 6 clusters on an- other vine, which were likewise covered, were rated 75, 80, 90, 95, 100, 100, respectively, averaging 90. Haton as a fertilizer.— It was tried as a fertilizer for Hercules. See page 378. ELDORADO. Eldorado self-pollinated— In 1894, 5 clusters of Eldorado which were kept covered during the blooming season, gave no > fruit. In 1895, 10 clusters; in 1897, 23 clusters; and in 1899, 4 clusters likewise tested gave no fruit. The following tests of Eldorado were made at Penn Yan in 1899: Eldorado pollinated with Brighton.— Five clusters tested gave uo fruit. Eldorado pollinated with Herbert.— Five clusters tested gave no fruit. Eldorado pollinated with Lindley.— Five clusters tested gave no fruit. Eldorado pollinated with Salem.— Five clusters which were tested were rated respectively 0, 0, 0, 0, 2. Average rating 0.4. ¢ 376 Report or THE HorricuLTuRIst OF THE Eldorado pollinated with Catawba.— Four clusters which were tested were rated, respectively, 0, 0, 0, 2. Average rating 0.5. Catawba is a self-fertile variety. In these tests self-fertile sorts have generally been good fertilizers for the self-sterile kinds. No explanation is offered for the exceptional results which fol- lowed the pollination of Eldorado with Catawba. There seems to be no good ground for the opinion that the Eldorado pistils were defective, for the clusters on the tested vines which were open to cross-pollination were unusually well formed, and some excellent clusters were also obtained by fertilizing Eldorado with Worden and Niagara. Catawba fertilized other self-sterile sorts very successfully in these tests, with the exception of Salem.° Eldorado pollinated with Worden.— Five clusters which were tested were rated respectively 20, 60, 75, 75, 95. Average rating 65. Eldorado pollinated with Niagara.— Five clusters which were tested were rated respectively 50, 60, 75, 95, 100. Average rat- ing 76. Eldorado as a fertilizer — Eldorado was tried as a fertilizer on two self-sterile sorts, Brighton and Herbert, under which varieties will be found the details of the tests. EUMELAN. Eumelan. self-pollinated.— In 1892, 10 clusters of Eumelan which were kept covered during the blooming season, gave no fruit. - In 1895, 9 clusters which were likewise tested gave no fruit. In 1893, 3 clusters which were likewise tested were rated respectively 0, 0, 4. Average rating 1.3. In 1899, 1 cluster which was likewise tested was rated 20. In view of all these tests it appears that with rare exceptions Eumelan fails to set any fruit when self-pollinated, and it may be classed as prac- tically self-sterile. 6 Salem fertilized by Catawba, rated 4, but only a single cluster was tested so that no conclusions can be drawn till the results are verified by further in- vestigation. New York AGRICULTURAL ExpPpERIMENT Station. 377 Eumelan pollinated with Black Hagle-— Two clusters tested at the Station gave no fruit. The work was done on the fifth day after Eumelan came into full bloom, and the treated clusters may have been too far advanced in bloom to give favorable results from cross-pollination. These tests should be repeated. HERBERT. Herbert self-pollinated.— In 1892, 2 clusters of Herbert which were kept covered during the blooming season gave no fruit. In 1895, 5 clusters and in 1899, 9 clusters, which were likewise tested, gave no fruit. So far as tested, Herbert has been found self-sterile. The following tests with Herbert in 1899 were made at Penn Yan: Herbert pollinated with Brighton.— One cluster which was tested gave no fruit. Herbert pollinated with Eldorado.— Four clusters which were tested gave no fruit. Herbert pollinated with Lindley.— Five clusters which were tested gave no fruit. Herbert pollinated with Merrimack.— Five clusters which were tested gave no fruit. Herbert pollinated with Salem.— Four clusters which were tested gave no fruit. Herbert pollinated with Worden.— Five clusters which were tested were rated respectively 95, 95, 95, 100, 100. Average rat- ing 97. Herbert pollinated with Niagara.— Four clusters which were tested were rated respectively 95, 100, 100, 100. Average rating 98.8. Herbert pollinated with Catawba.— Two clusters which were tested were rated respectively 100, 100. Average rating 100. Herbert as a fertilizer— Herbert was tried as a fertilizer on three self-sterile sorts, Brighton, Eldorado and Salem. See pages 372, 375, 381, respectively. 378 Report or THE HorricuLtTurRIst oF THE HERCULES. lercules self-pollinated— In 1893, 4 clusters of Hercules which were kept covered during the blooming season, bore no fruit. In 1895, 10 clusters tested in like manner gave no fruit. In 1899, 1 cluster covered in like manner produced a well-formed cluster made up entirely of small, seedless fruits. Hercules pollinated with Brighton.— Two clusters were tested in a ‘Station vineyard, one of which set no fruit, the other was filled with seedless fruits like the cluster described in the last paragraph. Hercules pollinated with Columbian Imperial.— Five clusters in a Station vineyard were tested. They were rated 20, 30, 30, 40, 50, respectively, averaging 36. Hercules pollinated with Eaton.— Five clusters in a Station vineyard were tested. They were rated 0, 0, 30, 70, 70, respec- tively, averaging 36. Hercules as a fertilizer.— Hercules was tried as a fertilizer for Barry. See page 370. JEFFERSON. Jefferson self-pollinated.— In 1893, 3 clusters of Jefferson were kept covered during the blooming season. They rated on the average about 95. In 1894, 4 clusters likewise tested were rated 0, 100, 100, 100, respectively, averaging 75. In 1899, 7 clusters were covered on a vine which afterwards appeared to be not in a satisfactory condition for testing. These clusters were rated 20, 20, 25, 45, 45, 60, 60, respectively, averaging 39.3. From these tests it appears that Jefferson is strongly self-fertile when the vine is in good condition. Jefferson as a fertilizer.— Pollen from the vine which in 1899 made the record which is given in the preceding paragraph, was tried on Brighton. See page 373. LINDLEY. Lindley self-pollinated.— In 1894, 10 clusters of Lindley, which were kept covered during the blooming season, set no fruit. In New York AGRICULTURAL EXPERIMENT STATION. 379 1895, 9 clusters and in 1897, 25 clusters, which were lkewise covered, set no fruit. In another locality, of 25 clusters which were likewise tested in 1897, 24 were rated 0, and 1 rated 40. . Average rating 1.6. In view of these tests, Lindley may be called practically self-sterile. The following tests with Lindley in 1899 were made at Penn Yan: Iindley pollinated with Merrimack.— Three clusters which were tested produced no fruit. Inndley pollinated with Salem.— Five clusters which were tested gave no fruit. Lindley pollinated with Brighton.— Three clusters which were tested were rated 0, 0, 12, respectively, average rating 4. Lindley pollinated with Catawba.— Five clusters which were tested were rated 40, 40, 55, 85, 95, respectively. Average rat- ing 63. Inndley pollinated with Worden.— Five clusters which were tested were rated 0, 50, 100, 100, 100, respectively. Average rat- ing 70. Lindley pollinated with Niagara. Five clusters which were tested were rated 40, 70, 90, 90, 95, respectively, averaging 77. Inndley as a fertilizer.— Several tests were made with Lindley as a fertilizer for self-sterile sorts. The results are given in detail for Brighton, Eldorado, Herbert, Merrimack and Salem under the several discussions of these varieties. MERRIMACK. Merrimack self-pollinated.— In 1892, 2 clusters which were tested, gave no fruit. In 1895, 10 clusters; in 1897, 23 clusters, and in 1899, 3 clusters, which were likewise tested, gave no fruit. From these tests it appears that Merrimack is completely self- sterile. The following tests with Merrimack were made at Penn Yan: Merrimack pollinated with Salem.— Five clusters which were tested, were rated 0, 0, 0, 0, 4, respectively. Average rating 0.8. 380 Report or tHe HorvricuLrurist oF THE Merrimack pollinated with Brighton— Four clusters which were tested, were rated 0, 0, 0, 35, respectively. Average rating 8.8. Merrimack pollinated with Lindley.— Four clusters which were . tested, were rated 0, 15, 15, 98, respectively. Average rating 32. Merrimack pollinated with Catawba.— Three clusters which were tested, were rated 90, 90, 95, respectively. Average rating 91.7. Merrimack pollinated with Niagara.— Four clusters which were tested, were rated 95, 95, 95, 100, respectively. Average rating 96.3. Merrimack pollinated with Worden.— Four clusters which were tested, were rated 90, 98, 100, 100, respectively. Average rat- ing 97. Merrimack as a fertilizer— Several tests were made with Merrimack as a fertilizer for self-sterile sorts. The results are given in detail under the discussions of Brighton, Herbert, Lind- ley and Salem. NEOTAR. Nectar self-pollinated.— In 1894, 6 of the 9 clusters which were kept covered during the blooming season were rated 0, 2 rated 2 and 1 rated 4, averaging 0.9 per cluster. In 1899, 2 clusters which were likewise tested, rated 80, 100, averaging 90. Further testing is needed to determine whether or not Nectar is strongly self-fertile. Nectar as a fertilizer.— It was tried‘as a fertilizer for Brighton. See page 372. NIAGARA. Niagara self-pollinated— In 1892, 10 clusters of Niagara, which were kept covered during the blooming season, gave perfect clusters, which rated from 97 to 100. In 1897, of 23 clusters at Penn Yan, which were likewise tested, 1 was rated 40, 5 rated 60, 3 rated 70, 9 rated 80, 8 rated 90, and 2 rated 100, respec- tively, averaging 75.7. Twelve clusters tested at Branchport were New Yorx AGRICULTURAL EXPERIMENT SraTion. 3881 rated 30, 40, 50, 60, 60, 60, 70, 80, 80, 80, 80, 100, averaging 65.8. In 1899, 16 Niagara clusters at Highlands were likewise tested. They were rated 85, 90, 90, 90, 93, 93, 93, 95, 95, 98, 100, 100, 100, 100, 100, 100, respectively, averaging 95.1. At Penn Yan, 20 clusters which were likewise tested, were rated 65, 80, 88, 90, 90, 90, 95, 95, 95, 95, 95, 98, 98, 98, 98, 98, 98, 100, 100, 100, respectively, averaging 93.3. Taking all these tests into consideration it appears that gen- erally Niagara is strongly self-fertile. Niagara as a fertilizer.— Several tests were made with Niagara as a fertilizer for self-sterile sorts. The results in detail are given under Aminia, Brighton, Eldorado, Herbert, Lindley, Merri- mack and Salem. ROCHESTER. Rochester self-pollinated.— In 1894, 10 clusters of Rochester, which were kept covered during the blooming season, all gave very compact and perfect clusters of fruit. One cluster, which was likewise tested in 1899, gave a perfect cluster of fruit, rated at 100. From these tests it appears that Rochester is perfectly self-fertile. Rochester as a fertilizer—It was tried as a fertilizer for Brighton. See page 373. SALEM. Salem self-pollinated.— In 1892, 10 clusters of Salem, which were kept covered during the blooming season, set no fruit. In 1897, 23 clusters in one locality, and 5 clusters in another, which were likewise tested, gave no fruit. From these tests it appears that Salem is completely self-sterile. The following tests with Salem were made in 1899 at Penn Yan: Salem pollinated with Brighton.— Three clusters which were tested produced no fruit. Salem pollinated with Herbert.— Five clusters which were tested gave no fruit. 382 Report or tHe HorricuLrurist OF THE Salem pollinated with Merrimack.— Four clusters which were tested gave no fruit. Salem pollinated with Lindley.— Four clusters which were tested were rated 0, 0, 0, 0, 2, respectively. Average rating 0.4. Salem pollinated with Catawba.— One cluster which was tested was rated 4. The test should be repeated and a large number of clusters tried before drawing conclusions on the value of Catawba as a fertilizer for Salem. Catawba gave similar results when used with Eldorado. See page 376. Salem pollinated with Worden.— Five clusters which were tested were rated 60, 90, 95, 100, 100. Average rating 89. Salem pollinated with Niagara.— Five clusters which were tested were rated 95, 95, 100, 100, 100. Average rating 98. Salem as a fertilizer.— Several tests were made with Salem as a fertilizer for self-sterile sorts. The results are given in de- tail under Brighton, Eldorado, Herbert, Lindley and Merrimack. STATION 125. Station 125 self-pollinated.— In 1899, 10 clusters of Station 125 were kept covered during the blooming season. They all gave perfect clusters, the average rating being 100. Station 125 is a white seedling of Winchell, fertilized with Diamond. Station 125 as a fertilizer— It was tried as a fertilizer for Brighton. See page 373. STATION 146. - Station 146 is a male vine, a seedling of Winchell fertilized by a wild vine of Vitis bicolor Le Conte. It is, therefore, a hybrid of V. labrusca by V. bicolor. It was tried as a fertilizer for Brighton. See page 372. STATION 156. Station 156 is also a male vine having the same parentage as: Station 146 which is given in the preceding paragraph. It was used as a fertilizer for Brighton. See page 372. New York AGRICULTURAL EXPERIMENT STATION. 383 VERGENNES. Vergennes self-pollinated.— In 1894, 10 clusters which were kept covered during the blooming season gave clusters of fruit which on the average were about as well filled and as compact as ordinary Concords. In 1897, 22 clusters which were tested at Penn Yan were rated 0, 0, 20, 30, 30, 30, 40, 40, 40, 40, 50, 50, 50, 50, 50, 60, 60, 60, 60, 60, 70, 90, respectively, averaging 44.5. At Branchport 5 clusters which were likewise tested, were rated 0, 0, 40, 40,40. They averaged 24. In 1899, 8 clusters were tested in a Station vineyard. They rated 70, 70, 70, 75, 80, 80, 85, 90, respectively, avéraging 77.5. On another vine which has stood in uncultivated ground and has repeatedly been overloaded with fruit, 9 clusters were also tested. These rated 0, 0, 0, 2, 65, 75, 85, 88, 95, respectively, and averaged 45.6. From these tests it appears that Vergennes is not always strongly self-fertile. Vergennes as a fertilizer—It was tried as a fertilizer for Brighton. See page 372. WORDEN. Worden self-pollinated.— In 1894, 10 clusters of Worden which were kept covered during the blooming season gave clusters which varied from perfect or nearly so to somewhat loose, averaging somewhat loose. In 1895, 9 clusters which were tested were per- fectly filled with fruit. In 1897, 23 clusters in a Station vine- yard were tested ; 2 clusters were rated 80, 4 rated 90 and 17 rated 100, respectively, averaging 96.5. At Penn Yan, of 20 clusters which were tested, 2 were rated 80, 7 rated 90 and 11 rated 100, respectively, averaging 94.5. At Branchport 5 clusters which were tested were rated 80, 80, 80, 90, 90, respectively, averag- ing 84. In 1899, 6 clusters in a Station vineyard which were likewise tested were rated 90, 90, 95, 100, 100, 100, respectively, and averaged 95.8. At Highlands, of 24 clusters which were tested, 3 were rated 75, 83 and 85, respectively, and 3 were rated 88, 8 384 Report oF THE HorrTICULTURIST OF THE rated 90, 5 rated 95, 2 rated 98 and 8 rated 100, respectively, averaging 93.7. At Penn Yan 20 clusters were likewise tested. Seven of these were rated 75, 90, 90, 95, 95, 95 and 98, re- spectively, and 13 were rated 100. The average was 96.9. From these tests it appears that Worden, generally, is strongly self-fertile. Worden as a fertilizer.— Several tests were made with Wor- den as a fertilizer for self-sterile sorts. The results in detail are given under Aminia, Black Eagle, Brighton, Eldorado, Herbert, Lindley, Merrimack and Salem. WYOMING. Wyoming self-pollinated.— In 1896, 10 clusters of Wyoming which were kept covered during the blooming season gave no fruit. In 1899, 4 clusters which were likewise tested at the Station were rated 0, 0, 0, 4, respectively. Average rating 1. At Highlands 13 clusters were kept covered during the blooming season. Twelve of them set no fruit. The remaining cluster was well filled. It was on a shoot which had been bent in tying it to the trellis so that the fiow of sap was somewhat checked. Before it had been rated it was taken by other parties. It would probably rank as high as 90. On the same vines the uncovered clusters which were exposed during the blooming season to cross-pollination were often well-filled, but sometimes loose and quite imperfectly filled clusters were found. At Highlands 6 clusters were hand-pollinated’ with Wyoming pollen taken from a vine in a Station vineyard. They rated 0, 0, 5, 10, 25, 90, respectively. Average rating 21.6. In view of all of these tests, it appears, that although Wyom- ing may sometimes produce a small amount of fruit when self- pollinated, for all practical purposes it may be ranked as self- sterile. The following tests were made in 1899 with Wyoming at High- - lands: 7 See foot note page 369. New York AGRICULTURAL EXPERIMENT STATION. 385 Wyoming pollinated with Aminia.— Four clusters which were tested, were rated 0, 0, 0, 8, respectively. Average rating 2. Wyoming pollinated with Brighton.— Six clusters which were tested, were rated 0, 0, 0, 0, 22, 50, respectively. Average rat- ing 12. Wyoming pollinated with Catawba.— One cluster which was tested formed a perfect cluster of fruit. It was rated 100. Wyoming as a fertilizer.— It was tried as a fertilizer on two self-sterile sorts, Aminia, page 369, and Brighton, page 371. SUMMARY OF RESULTS. In the following summary of the results of the investigation the data which have been given on preceding pages are arranged in Table II with reference to the ability of each variety to fertilize the self-sterile sorts upon which it was tried as compared with its ability to fertilize itself, and in Table III with reference to the varying degrees of fruitfulness which the self-sterile varieties ex- hibit when they are supplied with pollen from various varieties, some of which are more or less self-sterile and others self-fertile. Explanation of tables— The x between two names indicates that the variety following the x was used in pollinating the variety whose name appears before the x. Thus, Brighton x Aminia in- dicates that the Brighton clusters were pollinated with Aminia pollen in the manner described on page 364. The rating is on the scale of 100 points as previously explained, a perfectly formed and perfectly filled cluster ranking 100. The average rating is shown graphically and the number of tested clusters upon which the average is based is also stated. The highest rating which any single cluster in the test received is also given. “ Self-pollinated ” indicates that the tested clusters were simply kept covered in paper bags during the blooming season. Some- times the self-pollination was performed by hand, pollen from another vine of the same kind being applied in the manner de- scribed in the foot-note, page 369. Such tests are marked “ hand pollinated ” in the table. 25 386 Report or tHe HorvricuLrurist OF THE TABLE II.— CoMPARATIVE FRUITAGE WITH DIFFERENT VARIETIES OF GRAPES TRIED AS FERTILIZERS FOR SELF-STERILE Sorts. éule| 2 VARIETIES TESTED. bai 2 3 Graphic representation of average orl ee & rating. 3 o 2 oo EB) @| 5 ae se pee Aminia as a fertilizer: Self-pollinated.........- al Or uO, Self-pollinated..........

Its rating was somewhere between 80 and 100, mak- ing the average between 6.1 and 7.7. 390 Report oF THE HorTICcULTURIST OF THE By consulting the above table it is seen that Brighton and Wyoming when pollinated with the self-sterile variety, Aminia, were practically sterile and gave no better results than are ob- tained when they are self-pollinated. Black Eagle succeeded no better than Aminia as a fertilizer. It was tried on the self-sterile varieties, Barry and Eumelan. Brighton was not more effective in fertilizing the self-sterile sorts, Black Eagle, Eldorado, Her- bert, Salem, Aminia and Lindley than in fertilizing itself. Slightly better results were obtained when it was tried on Merri- mack and Wyoming, but nothing that would encourage the use of Brighton as a fertilizer for self-sterile sorts. Creveling, which is self-sterile, failed to fertilize Brighton. Eldorado, which is self- sterile, gave no results which would encourage its use as a fer- tilizer for self-sterile sorts, and the same is true of the other self- sterile varieties, Hercules, Herbert, Lindley, Merrimack, Salem and Wyoming. Occasionally the use of a self-sterile variety as a pollinizer for otker self-sterile kinds would result in the develop- ment of a good cluster as happened when Brighton was pollinated with Merrimack and again with Herbert, but even in such cases failure was the rule rather than the exception. On the other hand, the use of self-fertile varieties as fertilizers for the self-sterile sorts generally was attended with good results, as may be seen by examining the records of such varieties as Catawba, Worden and Niagara and Station 125. When certain varieties which are not strongly self-fertile, were tried as fertilizers for self-sterile sorts they generally succeeded in about the same degree as they commonly do in fertilizing themselves. This point is illustrated in the record of the tests with Eaton, Nectar and Vergennes. IS FAILURE IN SETTING FRUIT USUALLY DUE TO IMPERFECT PISTILS OR TO IMPERFECT OR IMPOTENT POLLEN 4 It is instructive to study the results of these investigations with reference to their bearing upon the question whether the failure to set fruit which has been observed among the self-sterile and the imperfectly self-fertile varieties may generally be attributed to weakness of the pistils or to imperfect or impotent pollen.. In New York AGRICULTURAL EXPERIMENT STATION. 391 order to facilitate the study of the evidence on this point, which was obtained in the 1899 investigation, the data are arranged in Table III so as to show in each case the results which follow the use of various kinds of pollen upon the pistils of one variety.

Report or tHe HorricuLrurist oF THE An examination of the results which are summarized in Table III, shows that Aminia gave scarcely any fruit when fertilized with the imperfectly self-fertile sorts, Brighton and Wyoming, but fruited freely when fertilized with the self-fertile sorts, Niagara, Worden and Catawba. Barry gave no fruit when polli- nated with either Black Eagle or Hercules, but clusters which were open to cross-pollination in a mixed vineyard, were well-filled with fruit. 8 The records of self-pollinated Herbert are summarized on page 387. 9 The records of self-pollinated Hercules are summarized on page 387. 10 The records of self-pollinated Lindley are summarized on page 388. 11 The records of self-pollinated Merrimack are summarized on page 388. 12 The records of self-pollinated Salem are summarized on page 389. 18 The records of self-pollinating Wyoming are summarized on page 389.

New York AGRICULTURAL EXPERIMENT STATION. 393 Brighton gave little fruit or none when fertilized with the self- sterile or imperfectly self-fertile kinds, Creveling, Salem, Aminia, Wyoming, Lindley, Eldorado, Merrimack and Herbert. The use of varieties having a higher degree of self-fertility gave corre- spondingly better results as is shown in the records of Nectar, Vergennes and Jefferson, while the use of strongly self-fertile kinds for fertilizers gave more perfect clusters of fruit as is shown by the records of Rochester, Catawba, Worden, Niagara and Sta- tion 125. Results corresponding to those given above were obtained with the different classes of varieties which were tried as fertilizers on Eldorado, Eumelan, Herbert, Hercules, Lindley, Merrimack, Salem and Wyoming. So far as these tests are concerned, they support the theory that the failure of self-sterile or imperfectly self-fertile grapes in setting fruit is not generally due to imper- fect development of the pistils because when they are supplied with pollen from strongly self-fertile grapes they set fruit abun- dantly. It has been observed that blossom buds of certain varie- ties may in some cases drop off before the flowers open. It has also been observed that when the vines are not in good condition certain varieties which generally produce well-filled clusters of perfect fruit may have a large proportion of imperfect clusters. It appears, therefore, that failure in setting fruit may be due to various causes, prominent among which is the lack of proper polli- nation. GRAPES CLASSIFIED ACCORDING TO THEIR BLOOM- ING SEASON. In selecting varieties of grapes to be used as fertilizers for those kinds which are either self-sterile or imperfectly self-fertile, it seems desirable to chose not only strongly self-fertile kinds, but also kinds which come into blossom at the same time with those which they are expected to fertilize. The following lists have been arranged to show approximately the comparative sea- son of blooming of the different varieties of grapes. The arrange- 394 Report or tHe HorricuLrurist oF THE ment is based upon the records for a series of years of the bloom- ing season of the varieties in the Station vineyards. A large part of these records for the varieties named below were published in Bulletin 157. In making the following lists the records for 1899 are also taken under consideration, and accordingly they do not exactly correspond with those which were published in the popular edition of Bulletin 157. The lists are arranged to show in parallel columns the strongly self-fertile kinds on the one hand, and on the other the imperfectly self-fertile and the self-sterile kinds. In all tests which have been made as to their self-fertility, when the vines were in normal condition, the former have on the average given marketable clusters, while the latter have given on the average either imperfectly filled clusters or none. In grouping the varieties so as to show their relative blooming season they have been classed as “ very early,” “ “ mid-season,” “ medium late,” “ late’ medium early,” ? and “very late.” These 14 lists do not show the relative season of ripening.“* There is no marked line of separation between the groups below. Many of the varieties extend their period of blooming into the period of the next later group, so that it is not always necessary, in arrang- ing the varieties for planting, to follow the classification rigidly. TABLE 1V.— GRAPES CLASSIFIED ACCORDING TO THEIR BLOOMING SEASON. [This table shows in parallel columns lists of grapes which bloom at ap- proximately the same time. The names of strongly self-fertile kinds appear on the left, and those of imperfectly self-fertile and self-sterile kinds, on the right.] STRONGLY SELF-FERTILE.

Some of the very earliest in blooming, as, for example, the Clin- ton, are late in ripening. New York AGRICULTURAL EXPERIMENT STaTion. 395 TABLE IV.— Continued.

A. Beacu, V. H. Lows anv F. C. Stewart. INTRODUCTION. The purpose of this bulletin is to furnish the fruit-grower with a concise account of the common diseases and insects most in- jurious to cultivated fruits in New York State and to present up- to-date directions for fighting them most efficiently and economi- cally. The accompanying index makes it easy to find any subject treated in the bulletin. The preparation of spray mixtures and the apparatus for ap- plying them are not treated here because they are discussed at length in Bulletin 121 and its appendix. Both Bulletin 121 and this bulletin should be preserved for reference. The various fruits are taken up in alphabetical order and under each one the diseases are first considered, then the insects. In the consideration of each particular disease or insect, it is the general plan of the bulletin to give first, one or more descriptive para- graphs setting forth its general appearance, the chief features of its life-history and its economic importance. Then follows a state- ment of the remedial or preventive treatment which is recom- mended or suggested by the authors. Where nothing can be posi- tively recommended, suggestions are made, pointing out what ap- pears to be the most promising line of treatment. Recommenda- tions quoted from other authors are given on their authority. In some instances it is possible to combat various diseases and insects with one general line of treatment. In such cases thé * Reprint of Bulletin No. 170. New York AGRIcuLTURAL EXPERIMENT Station. 3899 general treatment which is advocated is stated after the several diseases and insects have received individual consideration. APPLE DISEASES. APPLE TREE CANKER. (Sphaeropsis malorum Pk.) The term canker, as applied to diseases of trees, is used to des- ignate an injury that destroys the bark and lays bare portions of wood. It has been discovered that a canker which is doing serious damage to apple orchards of this State, is caused by the fungus, Sphaeropsis malorum Pk. This is the same fungus that causes the black rot of apple, pear and quince fruit. The disease usually attacks the larger limbs where it may be detected by the swollen appearance of the limbs, the rough, black bark, and in many in- stances bare wood, black and decaying. The area of bare wood is, in many instances, not large, but the extent of rough, swollen bark may be several feet. The wounds and unhealthy bark inter- fere with the circulation of the sap and where a majority of the limbs are attacked the tree is greatly enfeebled and may die from the effects. Some varieties, as the Esopus Spitzenburg and Twenty Ounce, are very susceptible to the attacks of this fungus, and many other common sorts are by no means exempt. Treatment.— No experiments in treating this disease have, as yet, been completed; therefore, no definite line of treatment can be given. The following suggestions are based on observations and studies of the disease as it occurs in a large number of or- chards: (1) Remove all diseased limbs wherever practicable. (2) When spraying with Bordeaux mixture for apple scab pay special attention to coating the limbs with the mixture as well as the leaves and fruit. An earlier treatment given when the leaf- buds are beginning to open may also be advisable. (3) In some instances it will probably pay to scrape or cut the diseased bark from the canker spots and scrape the rough bark from other por- 400 Report or tHE HorricuLrurRist OF THE tions of the tree. The trunk and larger limbs may then be washed with thick Bordeaux mixture or with one of the washes that are recommended for this purpose. The following formula is given as a type of these washes, as it contains the important ingredients: WasuH For TREE TRUNKS. Whale oll. soar ....%... {20 as SOP eee ethan tease ieee ote 1 pint.

When the ingredients have been reduced to a smooth state by stirring, dilute with water to four gallons, then stir in wood ashes till the wash is of the desired consistency. FIRE BLIGHT. The same as the “ Fire Blight of the Pear” discussed on page 443, FLY SPECK. (Leptothyrium pomi (Mont. & Fr.) Sace.) This disease, although commonly associated with sooty blotch, on both apples and pears, is probably distinct from it. It appears as groups of black dots resembling large fly specks. The specks are not caused by any insect but by a fungus which, like the sooty blotch fungus, is confined exclusively to the surface of the fruit. The treatment for fly speck is the same as for sooty blotch. See page 405. LEAF-SPOT. (Phyllosticta spp.) Description.—This disease is caused by two very closely related species of fungi. It attacks only the foliage. Very soon after the buds break, the young leaves show small, reddish-brown spots. As the leaves grow, the spots enlarge. When the leaves are full grown the spots are brown, brittle, circular, with sharply defined outline, and vary in diameter from one-twelfth to one-fourth of New Yorx AcricutTuRAL EXPERIMENT Station. 401 an inch. In July, several black specks of the size of a small pin head appear at the center of some of the spots, on the upper side of the leaf. Many spots, however, never show the black specks. Affected leaves fall prematurely. In severe attacks the trees may be almost completely defoliated by July 1. The disease is most troublesome in wet seasons. It is more prevalent on Long Island and in the Hudson Valley than in other parts of the State. Treatment.— Leaf-spot is only partially prevented by the treat- ment recommended for scab. See page 404. Where the disease is troublesome we suggest that this treatment be preceded by a spraying with Bordeaux mixture (1-to-11 formula) just as the buds show green at the tips. RUST. (Gymnosporangium spp. Syn. Roestelia spp.) Description, etc.— Rust is a disease in which circular, orange- colored spots about one-fourth of an inch in diameter appear on the leaves in June. It also produces yellow spots on the fruit at about the same time. It may be caused by several species of fungi belonging to the genus Gymnosporangium. ‘The species of this genus are peculiar in that in one stage of their life cycle they live upon the apple and some other closely related plants, while in another stage they inhabit the red cedar and its relatives. Gymnosporangiwm macro- pus is the most common cause of apple rust. Its other stage oc- curs on the red cedar where it produces the so-called cedar apples. In New England and some parts of the South apple rust is a destructive disease, but in New York it is of rare occurrence ex- cept on Long Island. Some varieties are attacked much more severely than others. Rust should not be confused with russeting. Treatment.— Rust is difficult to combat. Spraying seems to check it but little. Since the red cedar harbors one stage of the fungus which is the chief cause of rust, it is good policy to destroy, so far as practicable, all red cedars in the vicinity of the orchard. 26 402 Report oF THE HorricuLTuRIST OF THE RUSSETING AND BELTING OF FRUIT. Description.— Both apples and pears are subject to a trouble known as russeting or belting. It is sometimes also called rust, but this name is objectionable because it leads to confusion with the true apple rust discussed above which is a very different thing. Fruits entirely sound and perfect in form may show areas on which the skin is rough, brown and corky. These areas may be irregular in outline, in which case the fruit is said to be rus- seted, or they may form a definite zone around the fruit produc- ing the condition known as belting. Cause.— This trouble is not caused by any insect or fungus. It is due to some irritation of the skin of the fruit, and may be brought about in three principal ways: (1) By the occurrence of long continued cloudy, wet weather immediately after the setting of the fruit; (2) By spraying with Bordeaux mixture during cloudy, wet weather ; (3) By the freezing of dew on the fruit while it is young and tender. In this case the injured area usually takes the form of a zone or belt. No remedy is known. SCAB. (Venturia inequalis (Cke.) Aderh.*) Description.— The worst disease with which the apple growers apple scab” or “cracking of the apple.” It is caused by a fungus which attacks the skin of both foliage and fruit. On the fruit the spots at first usually circular in outline of this State have to contend is one commonly known as “ and have a very dark velvety-green surface, but afterwards they become nearly or quite black. In some eases the diseased tissue finally scales off leaving a scar with a corky, russet surface. The 1This is the name given to the ascosporic stage of Fusicladium dendriticum {Wallr.) Fekl. New York AGRICULTURAL EXPERIMENT Station. 408 spots vary in size from small dots to the large irregular patches which are formed when two or more smaller spots coalesce. Where the spots are large the fruit may become one sided or oth- erwise distorted, and often it cracks open. For this reason the disease is sometimes called “ the cracking of the apple.” On the leaves the fungus has the appearance of a dark mold. It is found in spots on both the upper and under surfaces. The disease may cause the leaves to be much crumpled and finally show brown, dead tissue which breaks away leaving the foliage torn and ragged, or the entire leaf may drop off. Some varieties are especially susceptible to its attacks, and it is not unusual to see a very large proportion of their fruit badly cracked by it. On the other hand, there are varieties which are generally quite resistant, on which the scab spots increase com- paratively slowly, and the cracking of the fruit is seldom or never seen. On the fallen leaves of the previous season, there develop, in the spring, perithecia within which are perfected spores for the propagation of the fungus.” The fungus is known to begin its attacks very early in the season, for occasionally it may develop sufficiently to be discovered by the naked eye on unopened blos- som buds. In seasons especially favorable to its early develop- ment it has been observed to cause great injury early in the sea- son, destroying the blossoms and the young fruit. In order to control the disease, therefore, it is important to begin treatment early. It must be borne in mind that the treatment is effective by preventing the germination of the spores rather than by kill- ing the fungus after it has become established either on the foliage or on the fruit. Treatment.— The scab may be controlled by proper spraying with Bordeaux mixture. Fortunately these treatments may be combined with others which are advocated by the Entomologist 2 Aderhold, Dr. Rud. Die Fusicladien unserer Obstbiiume, I. Theil Landw. Jahrbiicher, 25: 880-914, 1896. 404 Report or THE HortTicuLTURIST OF THE against the case-bearers, bud moth, canker worm, codling moth and other injurious insects. The combined treatment advocated for scab, leaf-spot, canker disease, codling moth, canker worms, and various other insects is given on page 417. As there stated, the scab may generally be controlled by three applications of the Bordeaux mixture if made at the proper time, and very thor- oughly. Where but three treatments are given, the first spray- ing should be made after the buds break but before the blossoms open; the second, just after the blossoms fall; and the third, from ten to fourteen days after the second. Winter treatment for apple scab— Spraying for apple scab while the buds are dormant has not been found profitable. The later treatments advocated above must be made in order to control the disease. When these are made the winter treatment does not bring sufficient additional benefit to justify the expense of making it against the scab alone, but it may pay when directed also against the canker disease and combined with some application which must be made against insects such as case-bearers or bud moth. It is known that the scab fungus lives during winter on the fallen leaves and in the spring produces spores by means of which it spreads to the new foliage. Probably it may exist during win- ter to some extent on the bark of young twigs, also. Granting that this is the case and that a large part of the fungus on the tree is killed by winter treatment, which is improbable, it is evi- dent that when the new foliage appears it must be covered with some fungicide to protect it from the spores produced on the fallen leaves. The fruit grower should direct his efforts toward prevent- ing the germination of the fungus spores on the foliage, rather than attempt to kill the fungus in winter quarters. The Bordeaux mixture treatment is a preventive rather than a cure. SCALD. Stored fruit of some varieties of apples, notably Rhode Island Greening, sometimes becomes discolored and presents an appear- New York AGricuLTURAL EXPERIMENT Station. 405 ance which is commonly called “scald.” It is not caused by any fungus. Jones® has made some investigations concerning the cause of scald. The following account is based on his reports. Description.— The scald first appears as a light brownish tinge of the skin either in fairly well defined spots or more or less dif- fused. The discolored areas enlarge with more or less rapidity coalescing until the entire surface of the apple may be involved. At the same time the color changes from a lighter to a darker brown shade and usually terminates in a black rot. At the begin- ning of the trouble the flesh appears sound, the discoloration in- volving only the outer cells of the fruit. Afterwards, the flesh also becomes discolored and is finally invaded, in most cases, by some fungus, but the primary cause of the scald cannot be attrib- uted to any fungus or other parasite. It appears certain that the primary cause of the scald is to be found in climatic and orchard conditions, the conditions of the storehouse being secondary. The fruit which is grown and matured under favorable conditions can be carried through the normal season of keeping for fruit of that variety without the appearance of the scald. If grown under unfavorable conditions the fruit requires very careful attention to the temperature and perhaps other store-room conditions if it is kept for any length of time without scalding. SOOTY BLOTCH. (Phyllachora pomigena (Schw.) Sacc.) Description, etc.—In wet seasons and especially in damp, shady situations, apples are subject to the attacks of the fungus which causes sooty blotches on the fruit. These blotches are sooty- black, circular, and measure from one-fourth to one-half an inch in diameter. Frequently the blotches coalesce, giving the fruit a sooty, dirty appearance. 3 Jones, L. R. Vt. Agr. Exp. Sta. Ann. Rept. 1896-1897: 55-59 and 1897- L898: 198. | 406 Report or rue HorricuLrurist OF THE Sooty blotch is sometimes mistaken for scab. A striking point of difference between the two diseases is the manner in which they attack the fruit. Sooty blotch is confined to the surface of the fruit and may be readily removed by rubbing, while the scab destroys the cuticle ( outer layer of the skin) thus making a spot which cannot be removed by rubbing. Being superficial in its growth, the fungus does the fruit no harm except to make it unsightly and, consequently, less salable. Under favorable conditions sooty blotch may appear upon almost any variety, but it seems to have a preference for some of the fair skinned varieties such as Bellflower, Fall Pippin and Rhode Island Greening. Pears, also, are subject to it. Treatment.— In orchards sprayed for apple scab the fruit will not, ordinarily, suffer much either from sooty blotch or the fly speck disease. However, for the best results with both of these diseases it seems necessary to make one or two sprayings in July in addition to those made in treating apple scab. APPLE INSECTS. BORERS. Several species of borers attack the apple tree. As a rule they will be found in the trunk, but occasionally in the larger limbs. A small species sometimes infests the twigs. The presence of the grubs is usually indicated by the discolored bark and by their castings. The following species are most commonly met with in this State: THE FLAT-HEADED APPLE-TREE BORER. (Chrysobothris femorata Fab. ) Description.— The female beetle lays its eggs in the bark late in June or in July. These hatch in a few days and the grubs at once gnaw their way into the sap-wood where they live and feed from one to three years before reaching full size. A short time before pupation they go deeper into the solid wood. The adults New Yorx AGricutTturaAL ExpERIMENT Sration. 407 ’ are steel-colored beetles, flattened above and with irregular depres- sions on the wing covers. Treatment.— The trees should be examined at least once a year and the borers dug out with a knife or killed by inserting a flexi- ble wire into the burrows. THE ROUND-HEADED APPLE-TREE BORER. (Saperda candida Fab.) Description.— The life-history of this species is similar to that of the preceding except that the grub requires but about a year to reach full growth. In both the grub and adult stages the body is more nearly cylindrical in outline. The adult is prominently marked by two broad, nearly parallel, white lines extending the full length of the body. Treatment.— The same as for the preceding species. LEAF-EATING INSECTS. THE APPLE-TREE TENT CATERPILLAR. (Clisiocampa americana Harr.) Description.—This tent caterpillar feeds upon a variety of fruit . and other trees and is especially injurious to the apple. The eggs are laid in July in conspicuous brown rings or masses about the smaller twigs. The caterpillar is developed in the egg in the fall but does not emerge from the egg shell till early in the following spring. The caterpillars from each egg mass form a colony and spin a tent in which they stay when they are not feeding on the leaves of the tree. After they are full grown, that is about five or six weeks after hatching, they spin their cocoons. The adults, which are brown moths, with two, oblique, parallel white lines on the fore pues emerge in the latter part of June or early in July. Treatment.— The egg masses may easily be gathered in winter and burned. The caterpillars may be destroyed while in their AOS Report or THE HorricuLturist oF THE nests or by applying a poisonous spray to the foliage. It is easier to kill the caterpillars by spraying when they are very small than it after they have become large. It is important, therefore, to make the first spraying just before the blossoms open because that is about the time the caterpillars emerge from the egg. The co- coons are quite conspicuous and their destruction will aid mate- rially in lessening the numbers of females to lay eggs. For further information relative to these insects and their near relatives, the forest tent-caterpillars, which are sometimes injuri- ous in orchards, consult Bulletins 152 and 159 of this Station. BUD MOTH. (T'metocera ocellana Schif.) Description and life-history.— The young of the bud moth are small brown caterpillars about half an inch in length. During the winter they live in small, oval, silken cases, attached firmly to the bark of the twig. As the caterpillars are very small when winter sets in, about one-eighth of an inch in length, their silken cases are also small and hence easily overlooked. During this period of their lives the caterpillars are green in color. About the time that the buds begin to swell in the spring, the caterpillars come forth and bore into them, thus early protecting themselves against insecticides. As the young leaves and flowers unfold the caterpillars form nests for themselves by tying the leaves together, making their presence quite conspicuous. They do not leave these nests in feeding. During June they reach full growth and change to the chrysalis stage in the nest. In about ten days a small brown moth escapes. This is the adult. The eggs are laid on the under side of the leaves. These soon hatch and the young caterpillars feed on the under sides of the leaves, protecting themselves by a thin, silken web. Before winter ap- proaches they migrate to the twigs and form the silken cases in which, as above stated, they live over winter. New York AGRICULTURAL EXPERIMENT STATION. 409 Treatment.— The only available time for effective treatment is just before the buds begin to swell, the object being to cover the buds with poison so that the young caterpillars will be poisoned as they gnaw into the bud. To make the work thorough, two ap- plications will usually be required. Paris green or some other good arsenical should be used. If it is desired to treat the trees for apple scab, Bordeaux mixture may be combined with the Paris green for either of the above treatments. See page 417. CASE BEARERS. PISTOL-CASE-BEARER.* CIGAR-CASE-BEARER. (Coleophora malivorella Riley.) (Coleophora fletcherella Fern.) During the past three or four years these two insects have be- come very troublesome in this State. Their principal food plant is the apple, but they also feed upon the pear and quince and probably other fruit trees. The life histories of the two species are very similar. That of the pistol-case-bearer is as follows: Descriptions and life history.—The young caterpillars live over winter in little pistol-shaped cases of silk which are attached on end to the twigs usually near and sometimes upon the buds. These cases measure about one-eighth of an inch in length and resemble the bark in color. The winter cases of the cigar-case- bearer are more flattened laterally and are somewhat crescent shaped. They are also lighter in color and are more frequently found in sheltered places in the angles of the twigs. Early in the spring, a short time before the leaf buds burst, the hibernating case-bearers become active. They attack the growing buds gnawing through the outer covering to feed on the tender tissues beneath. Later in the season they feed on the young leaves making small round holes through the cuticle and feeding, in much the same manner as a true leaf miner, on the softer tissues beneath. In doing this the caterpillars do not usu- ally leave their cases but reach out as far as necessary. As they 4 This species is discussed in detail by Lowe, in Bulletin 122 of this Station. 410 Report or THE HorricuLtTurist OF THE become larger and stronger they devour the entire leaf with the exception of the midrib and large veins. They also attack the flower buds, flowers and fruit. About the middle of May the case bearers have become full grown and are ready to pupate. They have enlarged their houses as their growing bodies demanded until now the cases measure about one-fourth of an inch in length. The case-bearers migrate to the twigs and attach their homes firmly on end to the bark. Before the transformation to the pupa stage takes place the cater- pillars turn around in their cases so that their heads are toward the upper or curved ends. The pupa stage lasts about two weeks. The principal difference in appearance between these two species 1s apparent at this time. The case of the cigar-case- bearer is straight and closely resembles a miniature cigar; while, as previously stated, that of the pistol-case-bearer slightly re sembles an old fashioned pistol. The adults of both species are moths measuring about half an inch from tip to tip when the wings are spread. The color of the former is steel gray, the latter is marked with brown. The moths appear during the latter part of May or early in June. The eggs of both species are deposited singly on the under sides of the leaves. They hatch in about ten days or two weeks. The young caterpillars feed on the tender pulp of the leaf. During September they migrate to the smaller branches and twigs, to remain until spring. Thus there is but one annual generation. Treatment.— For general treatment advocated against these insects see page 417. The first treatment is of especial impor- tance, the object being to have the buds coated with poison so that the first meal of the little caterpillars will be a poisoned one. A second application may be made just as the leaves unfold and a third if needed. CANKER WORMS. Although there are several species of canker worms quite com- mon to the apple orchards of the State there are but two species New YorK AGricuLTURAL EXPERIMENT Station. 411 that often occur in sufficient numbers to do serious injury. These are the spring canker worm (Paleacrita vernata Peck) and the fall canker worm (Anisopteryx pometaria Harr.) The former is the more common and injurious of the two. The life histories of the two species are very similar except that the eggs of the spring canker worm are laid in the spring and those of the fall eanker worm in the fall. The eggs of both species hatch in the spring about the time the leaf buds are unfolding. : Descriptions.— The eggs of the former species are placed some- what promiscuously in sheltered places on the twigs. They are small oval eggs and the shell has a brilliant pearly luster. The eggs of the latter species are placed on end side by side in quite regular masses. They are somewhat cylindrical but smaller at the base and flattened at each end. When first hatched the caterpillars of both species are very small and of a light green color. They devour the leaves rapidly. When disturbed they will drop, suspending themselves by silken threads. When mature they are about an inch long and vary in color from light green to darker shades. When ready to pupate they go into the ground, where the cocoon is spun and the chrysalis formed. Most of the spring canker worms remain in the ground until the first warm days of the following spring, but those of the other species come out of the ground in the fall. The adults of both species are moths. The females are wingless and the males winged. Treatment.— There are two principal methods of combating these insects. First the females may be trapped while endeavor- ing to ascend the trunk of the tree. Numerous traps have been - tested including bands of tin, cloth, waste wool, tarred paper and certain chemical preparations. Several patent metal devices for trapping the moths have been put upon the market recently. The most important point in connection with the use of traps in general is to put them on early in the season. It is usually advis- able to put the metal traps in place early in the fall to catch the 412 Report oF THE HorTICcULTURIST OF THE moths of the fall canker worm. They will then be in place for the earliest moths of the spring species. Second, the caterpillars may be successfully combated by spray- ing the trees with Paris green or some other equally effective arsenical insecticide. See page 417. Two and occasionally three applications are usually necessary. Make the first application just as the young leaves are unfolding, and the second about a wéek later. Regular annual spraying with a good arsenical compound is especially important in this case. Orchards thus treated are not as likely to become seriously infested with these and other leaf eating insects as the orchards which are sprayed irregularly or not at all. FRUIT INSECTS. CODLING MOTH. (Carpocapsa pomonella Linn.) Descriptions.— This is the insect that causes “ wormy ” apples. The recent investigations of Washburn, Card and Slingerland have thrown new light on certain stages of its lifehistory. It is now known that the eggs, which are whitish, oval dises, may be laid promiscuously upon the fruit or even upon the twigs and leaves. It is probable that they are not laid until after the blos- soms have fallen. The period of incubation is about a week. According to Slingerland® about 75 per ct. of the caterpillars enter the fruit at the blossom end. The caterpillars of the second brood often enter on the side of the fruit. They are full grown in twenty to thirty days. When once within the fruit they usually remain until ready to pupate. The cocoons are made in any con- venient, protected place, as under the loose bark of the trunk or larger branches of the tree, or in near-by rubbish. Some of the caterpillars remain in the cocoons over winter, while others soon transform to the pupa stage forming a more or less complete sec- 5 Cornell Univ. Agr. Exp. Sta. Bul. 142: 21. New York AGRICULTURAL EXPERIMENT STATION. 413 ond brood. These are sometimes very abundant in late summer and in autumn. The adult is a small brown moth measuring about # of an inch from tip to tip when the wings are spread. Those who wish an exhaustive treatise on this insect should consult Prof. Slingerland’s bulletin.® Treatment.—A considerable percentage of the worms can be killed by spraying within the first week after the blossoms have fallen. The calyx end of the fruit must be filled with the poison before the calyx lobes close, hence much pains should be taken to make at least one thorough application before that occurs. GREEN FRUIT WORMS. (Xylina sp.") Descriptions.— These insects sometimes do serious injury by eating into the young apples. They also attack pears, plums, peaches and quinces. The full-grown caterpillars measure from an inch to nearly an inch and a half in length. They are green or yellowish green in color with various irregular markings and stripes, the most prominent of the latter being a narrow, cream- colored one down the middle of the back and a wider one along each side. The caterpillars are most abundant during May, soon after the fruit has’formed. They continue feeding until about the middle of June. They feed mostly at night, resting on the under sides of the leaves during the day. When full grown they go into the ground, form a rough cocoon and pupate. The adults, which are dull-colored moths measuring about two inches from tip to tip with the wings spread, come forth in the fall and remain over winter in some sheltered place, laying their eggs in the spring. Treatment.— These insects have proven difficult to control. Experiments by Lowe with Paris green, one pound to 100 gal- lons of water, applied to the infested trees when the caterpillars 6 Loc. cit. 7 For a more complete account of these insects, see Cornell Univ. Agr. Exp. Sta. Bul. No. 123, by M. V. Slingerland. 414 Report oF THE HorTICULTURIST OF THE were about half grown, gave very unsatisfactory results. It is not improbable, however, that had the experiments been made earlier while the caterpillars were small the poison would have had more effect. Where practical, as in the case of small trees, the cater- pillars may be jarred off in the same manner as the plum cureulio. MAGGOT. (Rhagoletis pomonella Walsh. ) Description.— This insect is popularly known as the “ apple maggot” or “railroad worm.” It is one of the most important species that attacks the fruit. Its life-history has been fully worked out by Dr. F. L. Harvey.* The adult insects are two- winged flies. They appear in June. The female punctures the skin of the fruit with her sharp ovipositor and lays her eggs just beneath. In a few days the eggs hatch into white maggots which make numerous irregular channels in the pulp of the apple, enlarg- | ing them as the maggots increase in size. This injury often does not show on the outside, and hence infested fruit may be harvested and unintentionally sold as good. Badly infested fruit usually falls early. The maggots leave the fallen fruit and enter the ground to pupate, remaining until the following spring before emerging as adults. | The apple maggot appears to be spreading in this State, and as it is capable of doing great injury it should be carefully watched for and promptly checked when found. Treatment.— This insect has proven a difficult one to control. as the maggots work only within the fruit spraying the trees will have no effect. Probably the most practical remedy is the imme- diate destruction of the windfalls in infested orchards. This may be conveniently done by allowing hogs and sheep to run in the orchards. Fall plowing will have some effect by destroying many of the pup in the ground. 8 Maine Agr. Exp. Sta. Ann. Rept., 1889: 190. New Yorx AGRICULTURAL ExPpERIMENT STATION. 415 PLANT LICE.? Several species of plant lice attack the apple, but the most common in this State is the apple-tree aphis, Aphis mali Fab. This is the little, green louse that attacks the buds and leaves in the spring. It often occurs in great numbers on the under side of the leaves, sucking the sap from the tissues. This irritation causes the leaves to curl, thus affording partial protection to the insects. The winter is passed in the egg stage. Many generations and countless individuals, both winged and wingless, are produced during the summer. They secrete a clear liquid (honey dew) which sticks to the leaves and twigs and finally turns black, because of a black fungus which grows in it. Treatment.— The trees should be carefully watched, and, when the lice first appear, sprayed thoroughly with a solution of whale oil soap and water — one pound to seven gallons. The lice may appear any time after the buds burst. It is important to give the infested trees at least one or, as is often necessary, two thorough applications before the leaves have become curled. It will be very difficult to reach the lice when they are protected by the curled leaves. The spray should be directed toward the under side of the leaves. INSECTS ATTACKING TRUNK AND BRANCHES. THE WOOLLY LOUSE OF THE APPLE. (Schizoneura lanigera Hausm.) This insect is easily detected by the white wool-like substance which the lice secrete and which clings to their bodies. They attack both the roots and young branches causing gall-like swell- ings. They are especially injurious to young trees and sometimes do serious injury to new grafts. Treatment.— When occurring upon the roots considerable relief will usually result from the application of finely ground 9 For a further discussion of plant lice, see Bulletin 139 of this Station, by V. H. Lowe. 416 Report or tHE HorvTicuLTuRIsT OF THE tobacco dust about the infested roots. If the branches also are attacked, they should be trimmed off where practicable and burned. If considered more desirable, the lice may be killed by spraying with a solution of whale oil soap, one pound to five gallons of water, or kerosene emulsion, one part to five parts of water. When but few lice occur in small colonies on the trunk or large branches they may be easily and quickly killed by apply- ing pure kerosene oil to the infested parts. Some Australian horticulturists hold that injury from the woolly aphis can be avoided by selecting varieties the roots of which are proof against these insects. Wickson states’? that “ the Northern Spy is on the whole the best, but it has been shown that the roots of seedlings grown from Northern Spy seed vary somewhat in degree of resistance.” SCALE INSECTS.”* The scale insects include some of the most common and de- structive insect pests of the orchard. Two species common in the apple orchards of the State are the oyster-shell bark louse, Mytilaspis pomorum Bouché, and the scurfy bark louse, Chzonas- pis furfurus Fitch. The San Jose scale, Aspidiotus perniciosus Comst., also attacks the apple. These insects are especially in- jurious to young orchard trees. The former two species pass the winter in the egg stage, the eggs having been deposited under the scales of the females. The eggs hatch in this climate in the spring, varying according to the season, from late in April or early May until June. The young lice soon settle down and insert their sharp threadlike mouth parts into the tender bark from which they suck the sap. The females form the oyster-shell-like scales, or, in the case of the other species, the thinner, more oval, whitish seales. The scales of the males of both species are more delicate, nearly white, and larger and more slender. The adult males are delicate two-winged insects. 10 Univ. of Cal. Agr. Exp. Sta. Seed Bulletin, 1898-1899: 7. 11 For a further discussion of these insects, see Bulletin 136 of this Station. New York Agrrcutturat Experiment Srarion. 417 Treatment for oyster-shell bark-louse—Treatment may be made in the spring by spraying the trees as soon as the eggs hatch, either with whale oil soap, one pound to seven gallons of water, or kerosene emulsion, one part to seven parts of water. One or more applications should be made as required. For treatment of scurfy bark-louse, see page 450, and for San Jose scale page 449.

If used alone, about two pounds of fresh slaked lime should be added to make it adhere and to prevent injury when applied to foliage. Green ar- senite of copper, arsenite of lime, or other poison may be used instead of the Paris green, as directed in Bulletin 121. Paris green or the other arsenicals may be used with Bordeaux mixture. In that case, it is not necessary to add much extra lime. 13 Use Bordeaux mixture 1-to-11 formula. Pure copper sulphate solution, 1 pound to 15 gallons or more, may be used when there is no foliage. It is cheaper, but does not adhere so well as does Bordeaux mixture. Directions for making and applying these mixtures are given in Bulletin 121. The Paris green or other arsenicals may be mixed with the Bordeaux mixture, and both may be thus combined in one application. 27 418 Report or THe Horricutrurist oF THE Generally, the scab may be controlled by three treatments if they are made promptly and very thoroughly. These three, as numbered above, are 3, 4 and 5. Winter treatment against the scab is not recommended. See page 404. For treatment of lice or aphis, scale insects, rust, sooty blotch and fly speck consult the special discussion of these subjects on previous pages. APRICOT DISEASES. FRUIT ROT. The ripe rot of apricot fruit is due to the same fungus as that causing ripe rot of cherries. It is discussed on page 420. LEAF-SPOT. (Cylindrosporium padi Karst.) The fungus which causes apricot leaf-spot also causes a spotting of the fruit. When the leaves are attacked the diseased part usually drops out leaving a clean cut hole. In severe attacks the foliage is riddled with holes. The same fungus also attacks the foliage of plums and cherries. For the treatment, see plum leaf- spot, page 454. GUMMING. See discussion of the gumming of stone fruits, page 438, APRICOT INSECTS. CURCULIO. This insect does great damage to apricots by causing wormy fruit. Frequently a large part of the crop becomes infested and drops unless measures are taken to kill the beetles before they deposit their eggs in the young fruit. This is best done by jarring as recommended in the discussion of this insect under the head- ing “ Plum curculio.” It is very important that the jarring be gin as soon as the fruit sets, because the curculios do much injury to the very young apricots. New York AGRICULTURAL EXPERIMENT STATION. 419 The other insects mentioned as attacking the peach are also liable to trouble the apricot. BLACKBERRY AND DEWBERRY DISEASES. ANTHRACNOSE. Blackberry anthracnose is caused by the fungus which affects raspberries in a similar way. For description and treatment, see page 459. _ LEAF-SPOT. (Septoria rubt Westd.) Description.— Blackberries, dewberries and raspberries are sub- ject to a leaf-spot disease caused by Septoria rubi. The small, pale spots of dead leaf-tissue finally become dotted with black specks, the pyenidia of the fungus. In some seasons the foliage is quite seriously injured by this disease. Treatment.— Goft™ has tried treatment with Bordeaux mixture and other fungicides, but the results were not encouraging. No successful line of treatment is known. RUST. Blackberry rust is caused by the same fungus which causes the rust of raspberries. For description and treatment, see page 460. BLACKBERRY AND DEWBERRY INSECTS. The principal injurious insects of blackberry and dewberry are the cane borer and the saw fly. These also attack the raspberry. They are discussed on pages 461, 462. CHERRY DISEASES. BLACK KNOT. It is claimed that the black knot of the cherry is caused by the same fungus as that which causes the black knot of the plum, If it is not the same fungus it certainly is so closely related that the ' 14 Goff, E. S. Journ. Myc., 7: 22. 420 Rerort or THE HorricuLturist OF THE same description of gross characters and the same lines of treat- ment will apply to both. For description and treatment, see *“Plum black knot,” page 452, FRUIT ROT. (Monilia fructigena P.) Description.— The rotting of the ripening fruit on the tree often causes great injury to the crops of cherries, plums, apricots and peaches. A fungous parasite attacks the fruit and causes it to rot. The same fungus under favorable conditions, especially when the weather is warm and moist, and the growing shoots are tender and succulent, may attack the ends of the twigs and also the blossoms. Frequently the rotted fruit remains on the tree over winter in a mummied form and the following season, under favorable weather conditions, becomes covered with spores by means of which the disease is propagated. These mummied fruits, therefore, should be collected and destroyed before growth starts in spring, as a preventive of infection. The fungus sometimes does considerable damage by destroying the blossoms, but usually it causes most loss by attacking the fruit. It occurs on unripe fruits, but usually spreads most rapidly and does most damage when the fruits are nearly or quite ripe, especially if they hang in clusters or touch each other. Under weather conditions very favorable to its growth it may practically ruin the ripening crop within a short time. Treatment.— The disease may be prevented to some extent by treatment with fungicides, but it is extremely doubtful whether it ean be entirely controlled by spraying. Bordeaux mixture applied soon after the fruit sets persists, to some extent, until the fruit ripens and will show on the ripe fruit. The other mixtures which have been tried are of doubtful utility, taking all things into con- sideration. For both this disease and the leaf-spot it is suggested” 15 Beach, S. A. N. Y. Agr. Exp. Sta. Bul. 117: 134. New York AGRICULTURAL EXPERIMENT SraTion. 421 that the trees be sprayed just before blossoming and again imme- diately after the blossoms fall, but no line of treatment is recom- mended. Powell’® recommends picking the fruit before it is fully ripe; that is, before it softens. LEAE-SPOT. (Cylindrosporium padi Karst.) Description.— The leaf-spot of cherry, plum and apricot, which is caused by the fungus named above, at first appears as minute spots on the leaf, a sixteenth of an inch or less in diameter. On cherry and plum especially, the spots may have a reddish-tinged margin. Afterwards they increase in size and may enlarge to an eighth of an inch or more across. The spots soon become dark brown with a pale center, and in many cases the diseased tissue loosens and drops out leaving a clean-cut hole in the leaf. For this reason the disease is sometimes called the “shot-hole dis- ease." The disease may cause serious injury for sometimes the trees are nearly defoliated by it. Should this occur when the trees are heavily loaded with fruit, as it is especially apt to do with plums, the trees may be much weakened in vitality’® and con- sequently more liable to winter injury. Treatment.— It has been shown conclusively that the leaf blight may be controlled by proper treatment with Bordeaux mixture but in cherry orchards the treatments cannot be made at the most favorable time for controlling the disease because the spray mix- tures adhere to the fruit and injure its market value.” From our present knowledge of the subject no line of treatment can be positively recommended for bearing cherry trees, but it is sug- 16 Powell, G. Harold. Del. Agr. Exp. Sta. Rept. 1897: 193. 17 Duggar has shown that a shot-hole appearance in plum and peach foliage is not always due to fungous attacks, but may be caused by other injuries, notably by spraying with improperly prepared mixtures.

GUMMING. See discussion of gumming of stone fruits under gumming of the peach, page 438. To prevent gumming in the forks of cherry trees Wickson™ advocates training the tree in such a way as to give wide, open forks where the branches join the trunk. CHERRY INSECTS. CURCULIO. This insect injures cherries by causing the fruit to become wormy. It is the same insect as the plum curculio and is dis- cussed more at length under the subject “ Plum curculio,” on page 454. Treatment.— The curculio is commonly fought in cherry or- chards by one or two applications of Paris green or its equiva- lent at the rate of one pound to three hundred gallons of water. Two or three pounds, at least, of unslaked lime should be added for every pound of the poison. Slake the lime and add to the mixture the same as in making Bordeaux mixture. The poison may be mixed with the Bordeaux mixture if desired as stated on page 417. Make the first application immediately after the blossoms have fallen and a second about ten days later. FRUIT BARK BEETLE. This is the same as the fruit bark beetle of peach discussed on page 442. MAGGOT. (Rhagoletis cingulata? Loew.) This insect resembles the apple maggot in all of its stages. It attacks sour cherries and probably plums to some extent. It has 20 Wickson, E. J. California Fruits, p. 284. New York AaricutturaL Experiment Station. 423 recently proven a serious pest in some of the large cherry orchards of Western New York. A similar if not identical species occurs in some of the middle and eastern states. The life history of this insect has not been fully worked out. It is known, however, that the eggs are laid nearly or quite under the skin of the ripe fruit, and that the maggots work in the flesh. In depositing the egg the female makes a small round hole, prob- ably with her ovipositor, through the skin. Until the fruit has been sufficiently eaten to cause decay, this small hole is all there is to indicate that the maggot is inside. For this reason newly infested fruit is often quite difficult to detect. When full grown the maggots leave the fruit, as shown by specimens kept under observation by Lowe, and form the puparium or resting stage in any convenient place, such as the bottom of fruit baskets. If the fruit is on the ground the maggots will go into the ground for a short distance. The adults emerge in the spring early enough to lay their eggs in the earliest varieties of sour cherries. Egg laying probably continues throughout the season of the latest varie- ties. The number of broods is not positively known. The insect probably winters in the pupa stage. Treatment.— This species will probably prove, like the apple maggot, a difficult one to control. Good cultivation and keep- ing the packing houses free from rubbish will undoubtedly have some effect. Lowe found in the infested orchards which he ex- amined that the insect first attacked the fruit on a few trees in one section and gradually spread to other sections of the orchards. This indicates that it spreads slowly, and also that destroying the crop on the few trees that were first attacked, while an heroic measure, would probably be the means of preventing serious in- festation of the orchard, PLANT LICE. Several species of plant lice attack the cherry. As a rule they do not occur on sour cherry trees in sufficient numbers to do seri- ous injury. Sweet cherry trees, however, are quite frequently attacked by the black cherry aphis, Myzus cerast Fab. The lice 424 Report or tHE HorricuLTuRIst OF THE are nearly black in color. Like other species of plant lice they multiply with great rapidity, soon covering the under sides of the leaves and causing them, to curl and wilt. The lice prefer the young leaves at the tips of the branches, and will be found there in greatest numbers. Treatment.— Where practical cut off and burn the ends of the twigs bearing the young and worst infested leaves. The trees should then be sprayed avith whale oil soap solution or kerosene emulsion as recommended for the apple plant louse, page 415. SLUG. This insect also infests pear trees. It is discussed more fully under the heading “ Pear slug” on page 451. The remedies to be used are there given. CURRANT DISEASES. LEAF SPOT. (Septoria ribis Desm. and Cercospora angulata Wint.) These two fungous diseases which cause spotting of currant leaves have been successfully treated with Bordeaux mixture by Pammel.”! The spot diseases are usually seen to some,extent each season, and in some eases their attacks are so severe as to nearly defoliate the bushes. Judging from the experiments thus far tried, the spraying should begin soon after the fruit sets, and continue at intervals of about two weeks until the fruit begins to color. One or two applications may be made after the fruit is harvested if thought necessary. One objection to the treatments before the fruit ripens is that the mixture is liable to remain on the fruit and injure its appearance when ripe. Goff” has recently reported excellent results from a single thorough spraying with Bordeaux mixture made during the first week in July, after the fruit was harvested. | 21Pammel, L. H. Jowa Agr. Exp.

This disease is characterized by wilting of the foliage and dying of the canes. Healthy and diseased canes com- monly occur in the same hill. The disease may appear at any time during the growing season, but it is most virulent about the time the fruit is ripening. It appears that there are two forms of eane blight. The form occurring in the Hudson Valley” is caused by a sterile fungus which works in the pith and under the bark. In the western part of the State there occurs a currant cane blight which, according to Durand,” is caused by the semi-parasitie fun- gus, Nectria cinnabarina (Tode.) Fr. Treatment.— Probably the most practical method of fighting cane blight is to go over the plantation at frequent intervals dur- ing the summer and cut out and burn the affected canes. In doing this, care must be taken to cut well below the lowest, point of the disease. After cutting into diseased wood the pruning knife should be disinfected before it is used on healthy wood. A 5 per et. solution of carbolic acid is a good disinfectant for this purpose. Cuttings should be taken only from plants known to be healthy. CURRANT INSECTS. PLANT LICE. The first indications that the plant lice are at work are the small bladder-like galls on the upper surfaces of the leaves. The galls soon turn red, increase in size and may finally include nearly the entire leaf. The lice. congregate in large numbers in the corres- ponding pockets on the under sides of the leaves. Several species work on the currant, but the most common is the currant plant louse, Myzus ribis Linn. T'reatment.— The infested bushes should be sprayed with a solu- tion of whale oil soap, one pound to seven gallons of water. The 23 For an account of current cane blight in the Hudson Valley, see Bul. 107 of this Station, p. 291. 24 Durand, E. J. A Disease of Currant-Canes. Cornell Univ. Agr. Exp. Sta. Bul. 125. 426 Report or THe HorricuLrurist OF THE first application is the most important, and should be made as soon as the lice appear. The spray should be directed so as to hit the under surfaces of the leaves. A second and third applica- tion about a week apart may be necessary. SAW FLIES. (Nematus ventricosus Klug.) (Pristiphora grossulariae Walsh.) Description.— The first named species, which is popularly known as the imported currant worm, is much more troublesome than the latter, which is a native American species. The larve are the common “ worms” that attack the leaves of both the eur- rant and gooseberry, often quickly denuding the bush. The adults are four-winged flies about the size of a house-fly. Their bodies are prominently marked with yellow. They appear during the first warm days of spring and deposit their eggs in single rows on the under sides of the midribs and larger veins. The eggs hatch in about ten days. The newly hatched larvz are light green in color. At first they eat small holes through the leaves, but as they grow larger, devour the entire leaf with the exception of the midrib and larger veins. Their color changes with successive molts until, when about full grown and before the last molt, they are a moderately dark green color, marked with numerous black dots. After the last molt they are plain green. When full grown, which is in about three weeks, they measure about three-fourths of an inch in length. The cocoons are formed either just above or a short distance below the sur- face of the ground, attached to the plant. The adults escape late in June or early in July. Eggs are soon deposited for a second brood, which passes to the chrysalis stage before winter sets in. Treatment.— As soon as the “ worms ” appear spray the bushes with hellebore, one ounce to two gallons of water. Direct the spray toward the under sides of the leaves. It is important to make the first application while the “ worms” are yet very young. New York AGRICULTURAL EXPERIMENT STATION. 427 Otherwise it is more difficult to poison them. If a second appli- cation is necessary use an ounce of hellebore to one gallon of water. GOOSEBERRY DISEASES. LEAF-SPOT. The fungi which cause the leaf-spot diseases of the currant also attack the gooseberry. They are discussed on page 424. MILDEW. (Sphaerotheca mors-uwae (Schw.) B. & C.) Description.— The mildew usually makes its first appearance on the young shoots and leaves. Here it will first attract the observer’s attention as a collection of some bright, frosty sub- stance. On close examination it will be found to be composed of a mass of glistening white threads that spread rapidly under favor- uble conditions. The more mature portions of the fungus take on a dirty brown color. Later it attacks the fruit in a similar manner. ‘The threads often spread over the berries until they are entirely covered with a mass of brown, felt-like mold, which renders them unsalable. European varieties, when grown in this country, are particu- larly susceptible to the attacks of mildew. Many of those varie- ties produce very large, fine fruit and are so desirable both for home and market that they would be grown to a much greater ex- tent than they now are, were it not for the attacks of this disease. When setting out a plantation, a site should be chosen where the land is well underdrained and where there is an abundant cir- culation of air. Branches that droop close to the ground should be pruned back and the ground underneath kept free from grass _or weeds, preferably by frequent shallow cultivation, otherwise by mulching. Treatment.— Spraying should begin early in spring after the buds break and before the first leaves unfold, using one ounce of 428 Rerort or THE HorricuLTurIst OF THE potassium sulphide for two gallons of water. This treatment is repeated at intervals of from seven to ten days depending on the amount of rain that comes to wash off the applications. After the fruit is marketed spraying is no longer resorted to, although the mildew may continue through the season on the ends of growing shoots. SUN SCALD. The ripening fruit of the gooseberry is liable to sun scald. The skin at first has a bleached appearance and afterwards the fruit shrivels and drops. The conditions which bring about this trouble are not well understood. It sometimes causes serious loss. Remedy.— The only remedy known at present is to pick the fruit while it is green, 2. e., unripe. GOQSEBERRY INSECTS. The saw flies which attack the gooseberry are of the same species at those which are found on the currant. See page 426. GRAPE DISEASES. The various prominent vineyard diseases of the State, with the exception of the anthracnose, may be controlled by spraying ac- cording to directions given for treating the black rot, page 430. ANTHRACNOSE. (Sphaceloma ampelinum DeBy.) Description.— This disease attacks any tender portions of the growing vine. When the leaves are affected dark spots are first formed on their surface. As the disease advances these spots en- large, and irregular cracks are often formed through the dead tissue. Frequently many of these small cracks run together, form- ing a long irregular slit throvigh the leaf. Similar marks are formed on the tender shoots, though they are not so noticeable. When the fruit is attacked the disease is sometimes called bird’s- eye rot. Circular spots are formed on the surface of the berry. New York AGRICULTURAL EXPERIMENT StTaTIonN. 429 The spots may be of different colors and usually have a dark border; as the spots enlarge and eat in, a seed is often exposed in the center. The berries do not rot, but the tissue becomes hard and wrinkled. Sometimes the disease girdles the stem of a fruit- cluster, cutting off the supply of sap from the grapes beyond the diseased line and causing them to shrivel and die. Treatment.— Anthracnose does not spread as rapidly as some other vineyard diseases, neither does it yield as readily to treat- ment. When a vineyard is badly infested with anthracnose, it: requires prompt attention and careful treatment to control: the disease. It is not satisfactorily controlled by the Bordeaux mix- ture treatment alone, which is recommended below for black rot and mildew. It is suggested that in addition to such treatment the plan be followed which is advocated by certain European au- thorities, of applying a warm saturated solution of copperas (iron sulphate) in spring when the buds are swelling, but before they begin to open. One per ct. or more of sulphuric acid may be added to the solution before it is applied. This solution must - be handled with care as it is very caustic. It is applied with swabs or if the acid is not used it may be sprayed.” It is essential that ihe work be done thoroughly, covering all the surface of the canes. Mr. T. H. King, Trumansburg, N. Y., reports that he has been successful in controlling this disease upon the Vergennes, which is very susceptible to the disease, by pulling the loose bark from the vines and spraying thoroughly with Bordeaux mixture in the spring before the buds start and again three or four weeks later. BLACK ROT. (Laestadia bidwelliw (Ell.) V. & R.) Description.— This disease may usually be found first on the leaves, where it forms circular, bright reddish brown, or pale brown spots on which there appear later little black dots or pim- 25 Beach, N. Y. Agr. Exp. Sta. Bul. 86: 79. 1896. Lodeman, Spraying of Plants, pp. 45, 152, 294. 430 Rerort or tuk HorricuLtrurist OF THE ples. Within the black pimples are developed the germs of the fungus which causes the disease. These germs are given forth and washed by rain, or blown by wind, to other leaves or fruit where they grow and form new diseased spots. In the fruit it also forms circular spots and develops black pimples like those formed on the leaves. The diseased fruit withers, turns black, and becomes hard and shriveled, clinging to the stems sometimes till the following spring. The disease may also attack the green shoots. Treatment.— All diseased fruit shoud be taken from the vine- yard, since it is capable of spreading the disease the following spring. Trimmings from the fruit containing diseased berries ought not to be returned to the vineyard in the shape of compost as is sometimes practiced, since the diseased berries are liable to spread the black rot through the vineyard. This disease may be successfully controlled by thorough spray- ing if done at the right time. Bordeaux mixture, 1-to-11 formula, is used for this purpose. It is prepared as directed in Bulletin 121. The applicaticns are made as follows: I. Just as the pink tips of the first leaves appear. II. From ten days to two weeks after the first spraying. II. Just after the blossoming. LIV. From ten to fourteen days after the third treatment. V. If a fifth treatment is necessary let it follow the fourth after an interval of from ten to fourteen days. VI. If a later treatment than the fifth is needed, ammoniacal solution of copper carbonate should be used; as that it less liable to stain the fruit than the Bordeaux mixture. Directions for pre- paring it are given below. The number of the treatments should be governed by the weather conditions and the severity of the disease. If the vineyard is not badly diseased, and if there is not an excessive amount of hot, wet weather, four treatments may be found sufficient for all practical purposes. The early treatments are extremely important. Thorough treatment is essential to success. New York AGRICULTURAL EXPERIMENT STATION. 43817 Paris green or other arsenicals which are recommended against the insects, may be combined with Bordeaux mixture, but not with the ammoniacal solution of copper carbonate. Ammonical solution of copper carbonate.-—The formula usually given for making this solution is as follows: Dissolve five ounces of copper carbonate in three pints of ammonia of 26° strength. When ready to apply, dilute with water so as to make fifty gal- lons. The undiluted solution may be preserved for some time in tightly closed vessels. Penny finds”’ that the use of the strong undiluted ammonia in dissolving the copper is wasteful and unsafe. He recommends the following method of making the solution. ‘To one volume of 26° Beaumé ammonia (the strong ammonia of commerce) add from seven to eight volumes of water. Then add copper car- bonate, best in successive quantities, until a large portion remains undissolved. The mixture should be vigorously agitated during the solution and finally allowed to subside, and the clear liquid poured off from the undissolved salt. A second portion should then be made by treating the residue of the former lot with more ammonia diluted as before, then with the addition of fresh cop- per carbonate, in every case with vigorous stirring or agitation. The method of making in successive lots will result in a richer solution of copper, at least unless an unwarranted length of time be taken.” He finds that much less ammonia is required to dis- solve a given amount of copper carbonate in this way than ac- cording to the method formerly followed of adding the strong, undiluted ammonia directly to the copper carbonate. CHLOROSIS OR YELLOW LEAF. The name is applied to a grape disease in which the foliage turns yellow, later becoming brown. It is common in some parts of the State. 26 Del. Agr. Exp. Sta. Bul. 22. 432 Rerorr or tHE HorricuLrurist oF THE Chlorosis is more likely to appear in wet seasons. Some varie- ties, as the Diamond, are much more susceptible than others. In some seasons portions of the leaves may become yellow, but event- ually regain their normal color so that at the close of the season the vine appears to be in a healthy condition. In other instances the yellow color extends over the entire leaf; brown, dead patches appear; the leaf curls and eventually drops from the vine. If the vine loses its leaves two or three seasons in succession it is likely to die. One striking peculiarity of the disease is the fact that a badly diseased vine may appear by the side of a perfectly healthy vine of the same variety. The cause of chlorosis, as given by foreign investigators, is the presence of a large amount of lime in the soil which prevents the roots from taking up an amount of iron sufficient for satisfactory growth. Their experiments show that the difficulty may be over- come by applying a small amount of sulphate of iron around ‘affected plants. But since there are a number of good American varieties that are not subject to chlorosis, perhaps the better method to pursue is to plant only such varieties as are known to be free from this trouble. The standard varieties given in the following list are, so far as we know, practically exempt from chlorosis: ‘ Moore Early, Concord, Winchell, Catawba, Delaware, Vergennes, Worden, Agawam. Niagara, DOWNY MILDEW. (Plasmopara viticola (B. & C.) Berl. & DeT.) Description.— In some sections of the State the downy mildew causes considerable loss to the grape grower. It may attack nearly every portion of the current season’s growth,— leaves, shoots and fruit. Its first appearance on the leaves, that will be New Yorx AGRICULTURAL EXPERIMENT STATION. 433 noticed by a casual observer, is in dry, brick red spots on the upper surface. On the under side of the leaf the diseased area will be covered with the interlaced threads of the fungus. The red spots increase in size until in many instances the entire leaf dies and falls to the ground. It frequently causes the berries to turn dull brown and become soft and shriveled. This appear- ance of it has been commonly called “brown rot.” The spores are found on the threads which issue from the under side of the leaves or from the stems or fruit, the whole giving when fresh a glistening white downy appearance from which the disease takes its most common, and preferable name of “ downy mildew.” Later the parts of the fungus exposed on the surface assume a gray hue and so the disease has also been known as “ gray rot.” Some varieties, like Delaware, appear to be quite susceptible to the at- | tacks of the disease and none of the cultivated varieties are known to be entirely exempt. Treatment.— It may be successfully treated in the manner de- scribed for black rot. See page 430. POWDERY MILDEW. (Uncinula spiralis B. & C.) Description.— Unlike many of our fungous diseases, the pow- dery mildew flourishes best during the dry weather of mid-sum- mer. It usually begins its attack in June, though it may appear earlier. Its name is descriptive of its appearance, as it forms dull white, powdery patches on the young shoots on the upper surface of the leaves. When the fungus is abundant it seriously checks the growth of the vines by absorbing the nourishment that should have gone to their development. The berries may be attacked at any stage of growth and they are injured or destroyed in the same way as are the shoots or leaves. Treatment.— It may be successfully treated in the manner de- scribed for black rot. See page 430. 28 434 Report or tHE HorricuLtTurRist OF THE GRAPE INSECTS. CANE BORER. (Amphicerus bicaudatus Say.) A small cylindrical beetle, which works as a borer in its mature stage. It injures the grape by burrowing into the stems in spring near the base of the new growth. It breeds in the dying wood. The larva sometimes feeds upon the grape vines. Treatment. As it breeds in the dying wood, careful cutting away and destroying of such wood will help to check the insect. GRAPE-VINE FLEA-BEETLE. (Ialtica chalybea Ill.) Description The adult insects are shining steel-blue flea- beetles measuring about one-fifth of an inch in length. They live during the winter under the bark of the old vines or in rubbish in the fields. They emerge from their winter quarters during the first warm days of spring, and feed upon the opening buds and young leaves. Egg laying begins late in April or early in May. The eggs are placed singly near the buds or upon the leaves and hatch in about ten days. The young larvee are dark brown in color but soon become prominently marked with black dots and patches. They are full grown in from three to four weeks at which time they measure about a quarter of an inch in length. They feed on the leaves, devouring only the soft parts at first, but finally eating irregular holes through the leaves. When ready to pupate they go a short distance into the ground. The adults emerge from these pupzx during the latter part of June or early in July. They probably feed during all of the summer, finally seek- ing shelter for the winter as above indicated. Treatment.— The vines should be sprayed with Paris green, one pound to fifty gallons of lime and water, just before the buds begin to swell. Much pains should be taken to make this appli- New York AGRICULTURAL EXPERIMENT STATION. 435 cation thorough. Later, when the worms appear on the leaves, Paris green may be applied at the usual strength, one pound to 150 gallons of lime and water, or combined with Bordeaux mix- ture. Both upper and under surfaces of the leaves should be cov- ered. GRAPE FRUIT WORM. (Hudemis botrana Schiff.) Description.— The young caterpillars feed within the grapes finally causing them to turn dark colored and to wither. This injury is sometimes mistaken for the black rot. After devouring the soft parts of one grape the caterpillar goes to another, fasten- ing the two together by a silken thread. This may be continued until several in a bunch have been destroyed by one caterpillar. The young caterpillars are very light green in color with a brown head. When full grown they measure about one-fourth of an inch in length and are dark olive green in color tinged slightly with red. The cocoon is formed on a leaf and is partially com- posed of two small pieces cut out of the leaf. The adults emerge in about ten days. The fore wings have a bluish tinge and are marked with brown, while the posterior wings are dull brown. The moths are small, measuring nearly half an inch from tip te tip when the wings are spread. The eggs are probably laid late in June or early in July. There is probably but one brood an- nually in this State. Treatment.—As the caterpillars spend most of their lives within the grape berries, spraying will have little or no effect. There seems to be no better way than picking and destroying the infested fruit and the leaves containing the cocoons. GRAPE LEAF HOPPER. (Typhlocyba vitifex Fitch.) There are several species of leaf hoppers which attack the grape, but this species is probably the most common in this State. These 436 Report or THE HorricuLrurist oF THE little leaf hoppers are often erroneously called thrips. They jump quickly when disturbed. Description.— The adult insects measure about one-eighth of an inch in length. They vary greatly in color, but the prevailing color is usually light yellowish green. ‘The back and wings are ornamented with bright red, yellow and brown. They are found upon the vines from spring until fall. They feed together, suck- ing the sap from the leaves, principally from the under surface, causing them to turn brown in patches. Writers disagree as to the egg-laying habits of this species. The young resemble the adults in form, but are not provided with wings and are green or yellowish green in color. There are several broods during the season.‘ Some of the adults of the last brood hibernate in any convenient rubbish about the vineyard. Treatment.— The vineyards should be kept free from rubbish. Much good may be done by thoroughly spraying the vines with kerosene emulsion, one part to from seven to ten parts of water, or whale oil soap, one pound to seven gallons of water. This is not entirely satisfactory as many of the leaf hoppers will fly before the insecticide reaches them, but some benefit is derived from the emulsion or soap solution that remains on the leaves as it un- doubtedly makes them offensive to the insects. A practical method of combating this insect is found in what is popularly known as the shield method. The shield consists of a frame with a cloth stretched over it and saturated with kerosene oil, with tar softened until it is very sticky or with some other sticky substance. When ready for use it is carried in a horizon- tal position between the rows. The vines are agitated at the same time and as the insects fly or jump into the air many of them will come in contact with the sticky surface where they soon die or are wet with kerosene which is fatal to them. This method should be used during the warm part of the day and should be continued every day until the insects are materially lessened in numbers. New York AGRICULTURAL ExpERIMENT Station. 437 GRAPE-VINE SAW FLY. (Blennocampa pygmaea. ) Description.— The larva of this saw fly is a yellowish green slug, with numerous rows of black dots across the body. They feed together principally upon the under sides of the leaves. The life history of this species is similar to that of the currant saw-fly. See page 426. There are two annual broods. Treatment.— The infested vines should be sprayed with helle- bore, ene ounce to two gallons of water. If the spraying is not done until the larve are half grown or over, use one pound of hel- lebore to one gallon of water. Much pains should be taken to wet the under surfaces of the leaves. Paris green, one pound to 150 gallons of lime and water, may be used before the grapes are half grown. PEACH DISEASES. Caution.— Before discussing the diseases and insect enemies of the peach, attention should be ealled to the fact that the foliage of stone fruits and especially of the peach is peculiarly liable to injury from Paris green, London purple or copper in solution. For this reason the former should not be used stronger than one pound to about three hundred gallons of water and at least two or three times as much freshly slaked lime as poison should be used. It is doubtful whether more than two sprayings with Paris green or London purple should be given even if. diluted to the strength just stated. If Bordeaux mixture is used especial care | should be taken to have an excess of lime in the mixture. CROWN GALL OR ROOT KNOT. Descriplion, etc.— In this disease large knots appear on the roots. The knots are irregular in form, rough on the surface, sofe and spongy within and of various sizes, from the size of a pea to the size of a fist. They may occur on any part of the root system, but are found most commonly at the point where the roots branch off from the trunk; hence the name crown gall. 438 Reporr or tue LlorricuLTURIST OF THE Oceasionally, they occur also on the trunk above ground. In all cases the knots are detrimental to the trees and when they occur at the crown the tree is worthless. The disease is common in some of the nurseries in the State. The cause of it is wholly unknown. There are indications that it is infectious but this has not been proven. Similar knots oceur on the roots of the raspberry, blackberry, pear, apple, plum, apricot, grape, and a few other woody plants. Among fruit growers it is the popular opinion that the disease is the same on all of these different plants, and that any one of them may communicate the disease to the others. However, this has not yet been demonstrated by carefully conducted experi- ments. Treatment.— No remedy is known. Affected trees should never be planted. It is not even safe to plant trees from which the knots have been removed. Avoid planting fruit trees in soil known to be badly infested by the disease. FRUIT ROT OR RIPE ROT. (Monilia fructigena P.) The ripe rot of the peach is caused by the same fungus as that which produces the ripe rot of cherry and plum. It is discussed on age 420. | . Treatment.— Chester** who has given special attention to this subject advocates spraying with Bordeaux mixture just before the blossoms open and again after the fruit sets. Spray with copper acetate (finely powdered, 8 ounces to the barrel), when the fruit is ripening. Copper acetate does not discolor the fruit as Bordeaux mixture does. Observe the caution given above con- cerning the liability of injuring peach foliage by spraying. GUMMING. The formation of gum by the apricot, cherry, peach or plum may follow any injury by cuts or bruises or by the attacks of 27 Chester, F. D. Ninth Ann. Rept. Del. Agr. Exp. Sta., 1897: 28. New Yorx AcrictutTurRAL EXPERIMENT STATION. 439 insects or fungi. The young bark of stone fruit trees may be nearly covered with gum pockets as a result of bruises from hail stones. Wounds made in pruning are often followed by a flow of gum. It has been shown by some experiments that where the peach is pruned during the period of greatest vegetative activity, i. e., from April to August, there is a greater production of gum in the wounds than where the pruning is done later”. When gumming results from adverse conditions of environ- ment, of from over bearing, excessive pruning or any other cause which severely checks growth, it may often be remedied by mak- ing the conditions as favorable for growth as possible, as, for example, by frequent tillage, by the use of stable manure or other fertilizers, by draining the soil, by thinning the fruit to prevent overproduction and by treatment against diseases and injurious insects.” LEAF CURL. (Hxoascus deformans (Berk.) Fckl.) Description. The name is descriptive of the disease. The disease is caused by a fungus which not only attacks the leaves but may be found in the twigs as well. The curled leaves become distorted, crumpled, enlarged and curled. The disease may often be detected when the leaves first start from the buds in spring. The diseased leaves eventually fall so that in early summer the tree may be almost defoliated. In 1898 the disease caused a loss of many thousands of dollars to the fruit growers of the State by injury to the trees and by the premature dropping of the fruit which followed the loss of the foliage. Treatment.— It appears to be demonstrated that leaf curl may be largely prevented by spraying with Bordeaux mixture,” 1-to-11 28 Zeit. f. Pflanzenkrankheiten, 6 (1896): 58, 59. 29 For a more complete discussion of this subject, see Beach, S. A. “ Gum- ming of Stone Fruits.” Amer. Gard., 19 (1898): 606. 30 Some advise the use of copper sulphate solution, 1-to-15 or 1-to-20 for- mula, instead of the Bordeaux mixture, but we advocate the latter because it adheres so well. 440 Reporr or THE HorricuLTurRIst OF THE formula, in spring before the buds begin to open. Some advise later sprayings but as the peach foliage is very susceptible to injury from the use of spraying mixtures including even Bor- deaux mixture, we are not prepared at present to outline a satis- factory line of treatment for the foliage. LITTLE-PEACH DISEASE. This disease appears to have been first described by Taft®? in March, 1898. In October of the same year Smith® published a more extensive account of it. It seems to have been known to some extent among peach growers for many years.” It is con- sidered to be as contagious and as fatal as the yellows. Dr. Smith describes it as a disease in which the peach fruit is from one-half to one-third the diameter of healthy fruit, and it may ripen from one to two weeks later than the healthy fruit. The leaves average, perhaps, one-half normal size and have a sickly color. The larger roots appear to be all right but the ultimate | rootlets appear to be diseased. No fungous parasite has as yet been found to be the cause of the trouble. The remedy now advocated is the same as for yellows, viz.: Dig out and burn the diseased trees. YELLOWS. The best treatment for peach yellows is to dig out and burn the diseased trees. It has not been found that a healthy tree planted where a diseased tree stood is more apt to have the yellows than if planted elsewhere, other conditions being similar. Among the characteristics of the disease may be mentioned the appearance of clusters of willowy shoots, sickly color of the foliage, prema- ture ripening of the fruit and red colored spots in the flesh of the fruit. 31 Taft, L.

Description.—The adult insects are beautiful moths. The male measures about an inch and the female an inch and a half from tip to tip of the expanded wings. The general color is deep steel blue. The female has a broad band of orange across the abdo- men. ‘They appear during May and early June. The eggs are usually deposited on the bark at or near the surface of the ground, although they are sometimes deposited higher up on the trunk and even upon the larger limbs. The eggs are only a few days in hatching and the young larve quickly work their way into ihe sap wood where they feed during the remainder of the season. They remain dormant during the winter in their burrows, form a cocoon and finally issue as moths as above indicated. There is but one brood annually. Treatment.— As preventive treatment numerous washes have been suggested. In a series of expriements which included a large number of ‘trunk washes Slingerland® reports the best success with gas tar. The tar was warmed slightly to facilitate’ handling and applied to the trunk. It “apparently kept out four-fifths of all the borers, only a small percentage of the trees became infested and no injury resulted to the trees.” Professor Slingerland also states that in his experience “the tar did not interfere with the growth of the trees in the least.” This treat- ment should be combined with the digging out method. He also states that in this State the applications of washes, such as gas tar, should be made between June 15 and July 1, and “ should remain in perfect working order until October 1.” It should be remarked that gas tar is a substance of very variable composition and ‘instances are known where disastrous results to the trees followed its use in the manner which is here described. 35 Cornell Univ. Agr. Exp. Sta. Bul. 186, pp. 217, 224-225. $42 Report or tHe HorricuLrurist OF THE Keeping wood ashes about the base of the trees is considered by some extensive growers to be an effective treatment. The surest treatment is to kill the borers every spring and fall with a flexible wire inserted in their burrows or to remove them with a knife. After the borers are dug out in the spring in May, mound six inches high or more with fine earth, packing it tightly against the base of the tree. This compels the moths to lay their eggs on the bark above the top of the mound. About the first of August carefully examine the trunk by removing a little earth at the top of the mound where the borers, if any, may be easily found. Remove them with the knife. A second search should be made in October and a third one during the following May. If the earth is left at its usual level without mounding, the eggs are deposited so near the roots that the borers can easily work downward to where it will be difficult to find them. BUD MOTH. (7'metocera ocellana Schit. ) Sometimes very destructive to the peach. The caterpillars bore into the buds and even into the wood beneath. Treatment same as recommended on page 409. CURCULIO. The plum curculio is sometimes a serious pest in the peach orchard. Remedies for this insect are discussed under “ Plum eurculio” on page 455. FRUIT-BARK BEETLE. (Scolytus rugulosus Ratz.) Description.— The adult insects are black, somewhat cylin- drical beetles about one-tenth of an inch long and about one- third as broad. They appear early in the spring and bore small round holes through the bark to the sap wood. The eggs are laid beneath the bark and the grubs feed on the sap wood, mak- New York AGRiIcuLTuRAL EXPERIMENT Station. 443 ing characteristic galleries. Pupation takes place under the bark, the adults finally gnawing their way out. There are probably several broods in one season. It attacks a variety of fruit trees. Treatment.— As a preventive measure trees should be kept in a healthy, vigorous condition; as such trees are less liable to attack than weak ones. Trees which become badly infested should be dug up and burned. PEAR DISEASES. FIRE BLIGHT. (Bacillus amylovorus (Burr.) De Toni.) Description, etc.— This disease shows itself in the dying of en- tire twigs, large branches or even the tree itself. It is a bacterial disease that has long been known but whose real nature was first discovered in 1879 by Dr. Burrill of [llinois. It was afterwards studied very carefully at this Station by Dr. Arthur®’ and more recently by Mr. M. B. Waite * of the United States Department of Agriculture. The disease usually makes its first appearance soon after the blooming period. The young fruit clusters and the twigs bear- ing them turn black. The leaves also blacken and die but do not fall. If affected twigs are not removed the disease rapidly works its way down into the larger branches. According to Waite®® the blight germs do not live over winter in the soil. Moreover, he finds that in the majority of the affected branches even, the germs die soon after the close of the growing season. It is only in a small proportion of the affected branches that the germs survive the winter. Such “hold over” cases, as he calls them, become centers of infection during the following spring. Branches in which the germ is alive do not show »* definite line of demarcation between the healthy and diseased 36 See Annual Reports of this Station, 1884: 357; 1885: 241; 1886: 275. 387 Waite, M. B. The Cause and Prevention of Pear Blight. Year-Book U. S. Dept. Agr., 1895: 295-300. 38 Loc. cit. 444 Report or true HorricuLrurist OF THE wood. The infection is spread chiefly by insects, especially by bees. ot Se 4 Pear blight attacks several other pomaceous plants — the apple, erab apple, quince, ete. Treatment.—Although the cause of the disease is now well known no thoroughly successful method of treating it has been found. The only thing that can be done is to cut out and burn the diseased parts as soon as the blight appears. This should be done promptly; for the disease spreads rapidly. Waite recom- mends®™ that all trees subject to the disease be thoroughly in- spected several times during the growing season. He says that the two most important periods for such inspection are: (1) About two weeks after blooming; (2) just before the leaves drop. The cutting should be done several inches below the lowest point of discoloration, in order to make sure that all of the disease is removed. Care should be taken never to cut into healthy wood with a knife or saw that has come in contact with diseased wood, until after the tool has been disinfected by wiping it off with a cloth saturated with kerosene, a five per ct. solution of . carbolie acid, or some other germicide. LEAF BLIGHT. (Entomosporium maculatum Ley.) Description.—This is caused by a parasitic fungus which makes its appearance early in the spring. It is first found on the new leaves where it appears as bright, reddish spots on the upper sur- face. These spots rapidly increase in size and later the leaves turn brown and finally fall. It attacks the young twigs in the same manner and frequently kills back many of them. When the fruit is attacked the bright colored spots are first formed. These spots soon become dark colored, and spread out in every direc- tion; the surface of the pear becomes rough where attacked by 39 Fifty-Seventh Ann. Rept. N. Y. State Agr. Soc., 1897: 787. New York AGRICULTURAL EXPERIMENT Station. 445 the disease and at these places the growth is checked. Some- times the fruit becomes cracked as it does when attacked by the scab. This disease appears to be more severe in states south of New York and in regions near the Atlantic coast than it is in the interior of the State, where it causes little damage except as a mursery disease. Treatment.— The treatment advocated for pear scab is also recommended for this disease when it appears in the orchard. LEAF SPOT. (Septoria piricola Desm. ) Description.— This disease may be readily distinguished from the one last described if the two are carefully compared. The leaf spot when fully developed has a somewhat angular outline and whitish center in which appear small black specks, the bodies in which ihe spores of the fungus are borne. Treatment.— The only experiments in treating this disease which have come to our notice are those by Duggar*® who advo- cates similar treatment to that recommended against leaf-blight. SCAB. (Venturia pirina Aderh.**) Description.— This disease is caused by a fungus very similar, both in appearance and in the injury which it does to leaves and fruit, to the apple scab fungus. It robs the leaves of the nour- ishment which they are preparing for themselves and for the growth of the tree and fruit; it spots the fruit and in very severe attacks causes it to become one sided, distorted or cracked. While it does not kill the trees or branches as the blight may do, still it is believed that no disease, year after year, causes so great loss in pear orchards in New York State as does the scab. Some varieties appear to be comparatively exempt from its attacks while 40 Duggar, B. M. Cornell Univ., Agr. Exp. Sta. Bul. 145: 602-604. 41 This is the ascosporic stage of Fusicladium pirinum (Lib.), Fekl. 446 Report or THE HorTICULTURIST OF THE others suffer quite severely. With varieties which are thus in- jured by its attacks, it weakens the tree, it lessens the yield, it makes a large part of the fruit unsalable or of an inferior grade, and even the No. 1 fruit sells for less in the market than it would were it free from the blemishes caused by the scab. It is also conceded that fruit free from scab keeps better and is handled easier than the fruit of the same variety blemished with scab spots. Treatment.— This disease may be controlled by treatment with Bordeaux mixture.*” Paris green or its equivalent may be used at the same time against the codling moth and leaf eating insects. The general treatment recommended for the scab and other pear diseases 1s given on page 452. PEAR INSECTS. BARK LICE. See under ‘* Oyster-shell Bark-louse ” and “* Scurfy Bark-louse.” BLISTER MITE. (Phytoptus pyri Scheuten. ) Description.—The first indications of the presence of this insect in the spring are the small reddish spots on the upper surfaces of the young leaves. These spots indicate where the adult mites that have been hibernating on the twigs burrowed into the leaves to deposit their eggs. These spots finally turn black. The eggs soon hatch and the young mites burrow into the leaf, feeding upo™ its soft tissues. Toward fall the adults migrate to the twigs to remain all winter. There are probably several broods annually. T'reatment.—The infested trees should be sprayed in the spring a short time before the buds burst, either with kerosene emulsion diluted with seven parts of water or with a solution of whaleoil soap, one pound to seven gallons of water. One thorough appli- cation has been found to be sufficient. Pruning closely in winter and burning the twigs will also aid in checking the insect. 42 Beach, S. A. Bulletin 84 of this Station. New York AGricuLTuRAL ExpPpERIMENT STATION. 447 BORER. See “Sinuate Pear Borer.” BUD MOTH. The eyespotted bud moth which attacks pears, is the same as that which infests apple trees. It is also known as the bud worm. Treatment for it is given under apples. See page 409. CASE BEARERS. PISTOL-CASE-BEARER. CIGAR-CASE-BEARER. These insects also infest apple trees and have been discussed under appies. See page 409. CODLING MOTH. This insect which causes so much loss to apple growers by caus- ing wormy apples, also attacks pears. It may be treated as recommended on page 412. LEAF BLISTER MITE. See “ Blister Mite.” PEAR MIDGE. (Diplosis pyriwora Riley.) Description.—The first indication of injury by this insect is the stunted and dwarfed fruits. If one of these fruits is cut open the maggots will be found near the core. The adult insect is a small two-winged fly somewhat resembling a diminutive mosquito. According to Prof. J. B. Smith* it appears early in the season before the buds of the pear blossoms open. The eggs are probably laid in the blossoms and hatch within a few days. The young mag- gots bore into the embryo fruit, where they remain feeding near the core until full grown. When ready to pupate they leave the fruit and go into the ground to a depth of from one-half an inch to two inches. After remaining unchanged for a time they make 43.N. J. Agr. Exp. Sta. Bul. 99, page 5. 448 Report or THE HorvTicuLTURIST OF THE “ oval cocoons of silk covered with grains of sand” (Smith.) This probably takes place any time from early spring to mid-summer, depending upon the locality, although in this State most of them go into the ground in June. They remain as pupe in the ground all winter, emerging as adults in the spring. Lawrence pears are especially liable to attack. Treatment.— This insect has proved a very difficult one to con- trol. Experiments have been made with a view to destroying the pup in the ground, but it has been found that in order to sue- cessfully check the insect a dangerous amount of the insecticides tested must be applied to the soil. Hand picking, where practical, is probably the most satisfactory method of checking the insect. It should be done in June. OYSTER-SHELL BARK-LOUSE. This insect also has been discussed under apples, page 417. It is sometimes very injurious to young pear trees. PEAR PSYLLA. (Psylla pyricola Forst.) Description.— This insect causes injury in two ways. First, by sucking the sap; second, by disfiguring trees and fruit. Its pres- ence is usually betrayed by the honey dew secreted by the young, wingless forms. The honey dew afterwards becomes covered with a black mold giving the leaves and twigs a black unsightly appearance. The adult is an active four-winged insect measuring about one- tenth of an inch in length. It has been compared to a miniature seventeen year locust. A number of broods are produced during the summer, and the adults which live through the winter are distinct in form from the summer adults. They appear early in the spring and deposit their eggs in protected places on the bark. The eggs hatch within a few days and the little larvee, or nymphs, at once commence to suck the juices from the young leaves and New York AcricutturaAL Exprrrment Station. 449 twigs. Where the nymphs are numerous they take so much nourishment from the trees that the new growth is seriously checked. The whole tree assumes a stunted, unhealthy appear- ance. As a natural result the fruit crop is greatly lessened and, in some instances, trees have been killed. The first brood in the spring probably does the most direct injury. A favorite place for the young nymphs is in the axils of the leaves and at the base of the fruit stems. Within two or three days after hatching they cover themselves with honey dew which finally becomes so abundant as to disfigure the leaves and fruits, the amount of in- jury done in this way varying of course with the number of nymphs. Treatment.— The young nymphs are most easily reached. Close watch for them should be kept when the leaves are unfold- ing in the spring. As soon as the nymphs are found spray the trees thoroughly with kerosene emulsion diluted with about ten parts of water** or with a solution of whale-oil soap, one pound to from five to seven gallons of water. Two applications about ten days apart will probably be necessary. It is important to begin the work before the nymphs have covered themselves with honey dew as it is then much more difficult to reach them with a spray. SAN JOSE SCALE. (Aspidiotus perniciosus Comst. ) Description.”— This insect may be briefly described as a small, nearly circular, ash-gray scale with a prominent dark nipple at the center. These are the female scales. They are always greatly in excess of the males and are chiefly responsible for the injury which is done. The San Jose scale attacks the bark, leaves and fruit. In common with certain other scale insects it causes a 44Some growers use a much stronger emulsion than this with apparently no injury to the trees. 45 This insect is discussed more in detail in Bulletin 136 of this Station, pages 587-593, by V. H. Lowe. 29 : 450 Report or tur HorricuLturist OF THE crimson discoloration of the sapwood and fruit. It multiplies with great rapidity. In examining a tree for this insect the trunk and larger limbs and the fruit should receive an especially close scrutiny as the scales are often found here in large num- bers when only scattering on the smaller limbs. Treatment.—The treatment of this insect is a matter of so great importance that it will be made the subject of a separate bulletin. Where it has once become firmly established it probably cannot be exterminated. When recently introduced it has in some eases been exterminated by burning the infested trees, or by thorough treatment with whale-oil soap at the rate of two pounds to a gallon of water, or by both. The most effective known method of treatment is fumigation with hydrocyanic acid gas. The use of kerosene and water or crude petroleum is still in the experi- mental stage and cannot as yet be recommended for general use. SCURFY BARK-LOUSE. (Chionapsis furfurus Fitch. ) Description.— This insect sometimes occurs in large numbers upon young pear trees. The scales are a dirty white color, broadly wedge shape in outline and vary in length from about one-sixteenth to nearly one-eighth of an inch. The life history of this species is very similar to that of the oyster-shel! bark-louse; with both species the eggs are retained under the parent scale during the winter. The eggs vary greatly in number, from ten or twelve upwards, as many as seventy-five having been found under a single female scale. They hatch from the first to the middle of May. There is probably but one brood annually. The male scale is much smaller than the female, is elongate, with nearly parallel sides and is a clearer white color. The adult male is a delicate two winged insect. Treatment.— The treatment for this insect is the same as for the oyster-shell bark-louse. See page 417. . New Yorx AcricuLtturaAL Exprertment Station. 451 SINUATE PEAR BORER. (Agrilus sinuatus Oliv.) Description.— This insect was recently introduced into this country from Europe. It has become seriously injurious in some parts of the eastern United States. It makes long zig-za;, galleries between the bark and wood, finally girdling and killing the tree. It is said to live two years in the larval stage. The larva is slender, and has the first segment back of the head much enlarged. The adult is a small, slender beetle. The eggs are laid on the bark of the tree. Treatment.—When a tree becomes infested it is very difticult to get the borers out, and it is usually impractical to attempt to do so. As preventive measures some good may be done by plac- ing mechanical obstructions on the trunks, such as tarred paper wound about the trunk, or wire netting; the object being to pre- vent the adult from depositing eggs in the bark. Whitewashing the trunk with ordinary whitewash to which enough Paris green has been added to tinge it. slightly, or with a strong soap wash, one pound of whale oil soap to one gallon of water, has been recom- mended. ‘he trunks should be kept covered with one of these washes during May and June. PEAR SLUG. (Selandria cerasi Peck.) Description. The adult insect is a small, dark-colored, four- winged fly. The slugs make their appearance in the latter part of May or early June. At first light in color they soon become darker and are covered with an abundance of slime. The slugs feed on the upper surface, skeletonizing the leaves, and where very abundant they cause serious injury. Leaves that are badly injured wither and fall. Treatment.— If upon examination it is found that the insects are likely to appear in sufficient numbers to cause much damage, no time should be lost in spraying the trees with Paris green. If the trees are being treated for fungous diseases the Paris green 452 Report or THE HorrTicuLTurRist OF THE should be combined with the Bordeaux mixture. A _ second brood of this insect usually appears in August. The only thing to be done is to spray when the indications are that the slugs are numerous enough to be injurious. On low trees they are some- times treated with air-slaked lime or road dust, by throwing the dust or lime over the trees. GENERAL TREATMENT AGAINST DISEASES AND INSECTS WHICH ATTACK THE PEAR.

Description.— This disease causes swellings underneath the bark, finally rupturing it and developing a spongy texture covered 46 Use Bordeaux mixture, 1-to-11 formula. Directions for making and ap- plying are given in Bulletin 121. The Paris green or other arsenicals may be mixed with the Bordeaux mixture if desirable to apply both at one time. 47 Use Paris green at the rate of 1 pound to 150 gallons of water, with about two pounds of fresh slaked lime added to make it adhere, and to pre- vent injury to foliage. Green arsenite of copper, arsenite of lime, or other poisons may be used instead of Paris green, as directed in Bulletin 121. These arsenicals may be mixed with Bordeaux mixture instead of water, at a = rate as given above. In that case, not much extra lime need be added, New York AGRrIcULTURAL EXPERIMENT SraTion. 453 with dark olive-green mold. In this stage the summer spores are produced which spread the infection to other trees. Late in the season the knot becomes hard with a black surface, which finally becomes covered with fine black pimples inside of which are matured the winter spores. The winter spores escape late in winter or early in spring and serve to spread the disease. A more extended discussion of this disease is given in Bulletin 40 of this Station, and in the Annual Report for 1893, page 686. Treatment.— The best known remedy for this trouble is to cut out and burn the knots. They can be found most readily after the leaves have dropped in the fall. They should then all be -removed before mid-winter so as to be sure of destroying them before the spores mature and escape. Early in the summer the new knots should be watched for and promptly removed and destroyed. The infection frequently comes from the knots on neglected plum or cherry trees along fence rows or in neighbor- ing orchards. In removing the knots the branch should be cut off three or four inches or more below where the knot appears, so as to remove the threads of the fungus that may extend down the branch to a considerable distance from the knot. The same dis- ease also affects various wild plums and wild and cultivated cherries. It is rarely found on sweet cherries but sometimes is very destructive to the Morello class. FRUIT ROT. (Monilia fructigena P.) The ripe rot or fruit rot of the plum is caused by the same fun- gus as that which causes the rot of the cherry fruit. Treatment.— The treatment advocated for the leaf-spot will hold this disease in check somewhat. The spraying of the ripe fruit presents the same difficulties as it does with the cherry. See page 420. When there is reason to fear that the disease will attack the blossoms, treatment with Bordeaux mixture should be made just before the blossoms open. Thinning the fruit is no doubt a par- = 454 Rrrorr or tHE HorricuLturist OF THE tial preventive, because when the rot attacks one of a cluster of, fruits it usually spreads till every fruit in the cluster is diseased. When the fruits do not touch each other the disease is less destructive. LEAF SPOT. (Cylindrosportum padi Karst.) This disease is discussed under leaf spot of the cherry. See page 421. In general it is more liable to produce the shot hole appearance on plum foliage than on cherry foliage. Treatment.—As a result of extended experiments it can be stated that the plum leaf spot may be controlled by thorough treatment with Bordeaux mixture, 1-to-11 formula. In some seasons two treatments are most economical, but under conditions favorable to the disease at least three should be given.® If but two treatments be made give the first about ten days after the blossoms fall, but not later than June 1; make the second treat- ment about three weeks later. The disease may be better con- trolled by three treatments and usually three treatments will be most profitable. Make the third from three to four weeks after the second. YELLOWS. The Japanese plums are subject to a disease which has the appearance of peach yellows. It occurs on trees which have been worked on plum roots as well as on those which are on peach roots. No remedy is known. The treatment recommended is the same as that which is recom- mended for peach yellows — dig out and burn the diseased trees. PLUM INSECTS. PLUM CURCULIO. (Conotrachelus nenuphar Herbst.) Description.— The adult is a small, peculiar, gray beetle. It passes the winter under the bark of trees, or under rubbish, and 48 Beach, S. A. Sixteenth Ann. Rept. this Station, 1897: 211. New York AGRICULTURAL EXPERIMENT STATION. 455 comes forth early in the spring to deposit its eggs in the young fruits, commencing as soon as they are formed. It does this by puncturing the tissue and inserting the egg. After the egg is deposited, the beetle cuts a crescent-shaped groove around one side of the puncture evidently to prevent the growing tissue from crushing the egg. The eggs hatch in a few days when the little worm, or larva, at once commences to feed on the fruit causing much of the infested fruit to fall while still young and that which remains on the trees ripen prematurely and soon decay. The curculio does not confine its attacks to plums, but it usually infests plum orchards and if left unmolested, often destroys an entire crop. Treatment.— It has been found that the beetles’ manner of protection is to fall to the ground when disturbed. Here they curl up so as to resemble bits of bark. Advantage is taken of this habit in fighting the insect by a process known as jarring. The trees are jarred by three or four strokes with a padded crutch or mallet and the insects are caught on sheets spread underneath the tree and destroyed. The curculio catcher commonly used in the vicinity of Geneva is one made by Mr. J. B. Johnson, Geneva, N. Y. The frame over which the sheet is stretched is attached to a two-wheeled cart. The sheet slopes downwards to the center where an open- ing allows the bugs to be swept into a tin box underneath the sheet and between the wheels. A slit at one side allows the cart to be run directly under the tree and two or three jars bring down the bugs which are swept into the box above mentioned, by means of a short handled broom. The cultivated ground is made smooth by rolling to prepare it so that the cart wheels will pass over it readily. Jarring should be begun as soon as the fruit sets and be continued as long as the curculio are found in sufficient numbers to pay for jarring, which is usually for about three weeks. arly morning is the best time to do this work. Towards the middle of the day, especially on bright days, they are more active and apt to fly. , 456 Report oF THE HorricuLTURIST OF THE The beetle feeds on the plum leaves and for this reason spraying the trees with Paris green or London purple has been advocated. No doubt the insects may be killed to some extent in this way but the foliage of stone fruit trees is particularly liable to injury from Paris green or London purple so that these poisons must be used sparingly and much diluted. When the insect is abundant the jaring is undoubtedly the best way of controlling the pest. GREEN FRUIT-WORMS. The green fruit worms sometimes are so abundant on the plum as to cause much damage. The treatment recommended is given on page 415. PLANT LICE. Several species of plant lice attack the plum. They collect in great numbers on the under sides of the leaves, causing them to curl and finally drop off. The infested trees should be sprayed with whale-oil soap, one pound to seven gallons of water, as soon as the lice appear. The spraying should be directed from the under side so as to reach all of the lice. QUINCE DISEASES CANKER OF TREE. BLACK ROT OF FRUIT. The canker of the tree and black rot of the fruit of the quince are caused by the fungus which causes similar trouble with the apple and pear. For a discussion of the disease and remedial measures see page 399. BLIGHT. (FIRE BLIGHT.) This disease is caused by the same parasite which produces the fire blight of the pear. It is discussed on page 443. LEAF BLIGHT AND FRUIT SPOT. (Entomosporium maculatum Lev.) Description.— Fruit spot and leaf blight of the quince are caused by the same fungus that causes pear leaf blight. When a New Yorx AcricutturaL Exprriment Station. 457 fruit is attacked, numerous small black specks appear on its sur- face. As the spots increase in size they often grow into each other and form a large, dark, diseased area. The disease does not extend so deep into the tissue of the fruit as to make it entirely worthless, but the market value is greatly lessened. When the fruit is at- tacked before it has reached its full size, it often occurs that the quinces, like the diseased pears, are mishapen and undersized. Greater damage is done to the trees when the leaves are severely at- tacked. The loss of foliage in midsummer not only leaves the fruit undeveloped but it is a severe check to the growth and vigor of the tree. Treatment.— Favorable results in treating this disease with the Bordeaux mixture are reported. It is suggested that the treat- ment recommended for apple scab be used against quince fruit spot and leaf blight, making the first spraying when the blossom buds have appeared, the second just as the blossoms are falling, and a third about two weeks later. RUST. (Gymnosporangium spp. ) Description.— The rust is due to a fungus which becomes estab- lished and develops within the tissues of the quince branches or fruit. It causes knotty branches and peculiarly distorted fruit on which there appear tiny fringed pits filed with orange colored dust giving the diseased parts quite a brilliant appearance. In a different form this rust fungus attacks the red cedar and the common juniper, forming galls on their branches. In these galls are developed spores which, distributed by the winds to quinces, juneberries, hawthorns and apples, become established on these trees and cause the rust. Usually the rust is not abun- dant enough on quinces to cause serious injury. It is usually recommended that the cedar and juniper trees in the vicinity be destroyed to prevent the breeding of the fungus on them and that the rusted fruit or branches also be removed and destroyed. The 458 Report oF THE HortTicuLrTurRIsTt OF THE former recommendation is not always practical, and whether the latter course will do any good has not been definitely determined. QUINCE INSECTS. BORER. These are the same as those described under apple insects, page 406. The trunks of the trees should be examined carefully in spring and fall and the borers dug out. Various other remedies have been advocated, but apparently none of them take the place of systematically removing the grubs. CODLING MOTH. (Carpocapsa pomonella Linn.) This insect is the same as that which causes wormy apples and pears as described on page 412. It should be treated by spraying with Paris green or some other arsenical poison as soon as the fruit sets, followed by one or two later applications at intervals of ten days, or even less if heavy rains fall in the meantime. The poison thus used is also recommended for the curculio mentioned below. It may be combined with Bordeaux mixture when that is used against fruit spot and leaf blight, using one pound for one hundred and fifty gallons. CURCULIO. (Conotrachelus crataegu Walsh.) Description.— The adult insect is somewhat larger than the plum curculio. It is broader just back of the thorax and is a brownish gray color mottled with white. Its life history as worked out by Slingerland® is substantially as follows: The winter is passed in the grub stage in an earthen cell two or three inches below the surface of the ground. Here the transformation to the pupa takes place in the spring. The time when the adults 49 Cornell Univ. Agr. Exp. Sta. Bul. 148. New York AGRICULTURAL EXPERIMENT Station. 459 emerge varies with the weather conditions. They may appear any time from late in May until late in July. The adults feed on the young quince fruits and possibly on the leaves. The eggs are laid in “ little pits” made by the female beetles in the fruit. The eggs hatch in a few days and the grubs feed in the fleshy part of the fruit until full grown when they go into the ground to pass the winter. There is but one brood annually. Treatment.— As-with the plum curculio, jarring is considered the most satisfactory method of combating this insect. The trees are jarred in the same manner as plum trees for the plum curculio. > is mounted on low wheels so that it can The “ cureulio catcher ’ be used under the quince trees. As the time when the curculios appear varies, probably with the season, no definite time for be- ginning the work of jarring can be given. The trees should be watched after the last week of May. The presence of the cur- culios will be easily ascertained by a few trials at jarring. If they are found the jarring should be continued as long as they are numerous. RASPBERRY DISEASKS. ANTHRACNOSE. (Gloeosporium venetum Speg.) Description.— This disease ordinarily makes its first appear- ance on the young canes when they are less than a foot high. Its presence may be detected by the appearance of small dark or purple colored spots, which rapidly increase in size and change from the dark color to the brown or dirty white in the center as the fungus feeds outward in all directions leaving the dead tissues behind. The slightly raised outlines of the spots vary in color from dark brown to bright purple. In severe attacks the spots are so numerous that they soon coalesce and form continuous blotches that may nearly or completely girdle the cane. The effect on the cane is practically the same as if so much bark had been removed with a knife. While anthracnose is preéminently 460 Report or tHe Horricu,trurist oF THE a disease of the canes it may occur on any part of the plant above ground. It is most destructive to black raspberries, but also attacks purple raspberries and blackberries and perhaps still other species of Rubus. Red raspberries appear to be exempt. T'reatment.*°— Since, in most instances, a raspberry plantation reaches its limit of profitable production when three or four years old it seems that a rotation of crops, combined with sanitary measures, is the surest method of preventing loss from this disease. As the disease lives over winter in the canes, the old canes, to- gether with the badly diseased new ones, should be removed as soon as the fruiting season is over. Experiments have shown that the disease may be checked by spraying with Bordeaux mixture, beginning when the new canes are about six inches high and keeping them well protected with the mixture until the fruit is two-thirds grown. Ordinarily, how- ever, spraying for anthracnose is not likely to pay. RUST. (Puccima peckiana Howe. Syn. Caeoma nitens Schw.) Description, etc.— This disease is often called the orange rust on account of the orange color of the spores which are produced in dense masses on the underside of the rusted leaves. Sometimes the spore masses occur also on the canes. The fungus attacks blackberries, dewberries and raspberries. It is quite common on wild plants and where these are growing in the vicinity of cul- tivated varieties the diseased plants among them should be de- stroyed to prevent them from becoming a source of infection. Treatment.— Clinton™ states that the fungus enters the- very young underground shoots and growing up through the canes finally appears in the leaves. Since the fungus grows within the canes and infection appears to take place at the root, the only 50 Paddock, W. The Anthracnose of Black Raspberry. N. Y. Agr. Exp. Sta. Bul. 124. 51 Clinton, G. P. Orange Rust of Raspberry and Blackberry. Ill. Agr. Exp. Sta. Bul. 29. a a So New Yorx AgricutturaAL Experiment Station. 461 preventive treatment which can be recommended is digging out and burning the infested plants immediately upon the first ap- pearance of the disease. ‘This treatment will materially check the disease. Affected plants may usually be detected before the rust breaks out on the leaves. The diseased leaves have a pale orange tinge and present a sickly appearance which one soon comes to recognize as characteristic of rust-infested plants. Di- seased canes are also apt to be much freer from prickles than are healthy canes. LEAF-SPOT. (Septoria rubi Westd.) A leaf-spot of raspberries is caused by the same Septoria which attacks blackberries. It is discussed on page 419. The disease seems to be less troublesome on raspberries than it is on blackberries. ROOT KNOT. The roots of raspberries are often covered with galls which are similar to those found on peach roots (see page 487) and are probably due to the same cause. Our knowledge of these root galls is imperfect. To both raspberry and the peach they are very injurious. There is some reason for believing that the di- sease may be communicated from the peach to the raspberry and vice versa. Hence it is advisable to avoid planting peaches on soil in which raspberries have knotted badly. Neither should raspberries be planted where peaches have been affected with the root knot. RASPBERRY INSECTS. CANE MAGGOT. (Phorbia sp.) Description.— This insect works only in the new shoots causing them to wilt and finally die. This wilting of the shoots is first noticeable in May. The adults first appear in spring toward the 462 Report or THE HorricuLtTurRist OF THE latter part of April. The eggs are laid near the tips of the new growth. They hatch within a few days. The little white maggots which emerge from them burrow into the pith of the shoot. Ac- cording to Slingerland™ they burrow downward in the pith until they have reached about half the length of the canes when they work nearly out to the bark and each makes a tunnel around the shoot, thus girdling it from the inside. They continue feeding on the pith at the point where the girdling was done, almost severing the shoots. After doing this injury the maggots proceed to mur- row downward in the pith, finally reaching the base of the shoots where they transform to the pupa stage. This point in their development is probably reached some time in June. They re main in this condition until the following April. Treatment.— As the insects work inside the shoots they cannot be reached with a spray. Undoubtedly the most practical method of treatment consists in cutting off the wilted shoots several inches below the wilted portion. SAW FLY. (Monophadnoides rubt Harr.) Description.— The adult insects are about the size of a house- fly. They appear in the spring and are most abundant in May. The eggs are laid from the under side of the leaf within the leaf tissue. They are usually placed along the midrib and larger veins. The tissue above the eggs turns a light brown in color, causing the infested leaves to become spotted. The eggs hatch in about a week. The young larve are light green in color and are well cov- ered with spine-bearing tubercles. They feed at first on the softer tissues, but finally the entire leaf with the exception of the mid- rib and larger veins is devoured. They also have been known to feed on the tender bark of the new growth and to do some injury to the flowers and fruit. Toward the latter part of June they go into the ground near the bushes upon which they have been feed- 52 Cornell Univ. Agr. Exp. Sta. Bul. 126, p. 58. New York AGricuLtturAL ExpreriMentT Station. 463 ing, to a depth of two or three inches, where the cocoons are spun in which the transformation to the pupa stage slowly takes place. The transformation is not completed until the following spring. There is but one brood annually. Treatment.— If the leaves become spotted as above indicated, they should be examined, and if indications of the eggs or larvze are found they should be sprayed with hellebore, one ounce to the gallon of water, as soon as the young larvee are numerous. Both the upper and under surfaces of the leaves should be covered. Where only a few bushes are infested the insect may be easily checked by brushing the larve onto the ground about the bushes. If the ground is soft and loose most of the larve will be unable to return. STRAWBERRY DISEASES. LEAF-SPOT. (Sphaerella fragariae (Tul.) Sacc.) This disease is also called strawberry “rust” or “ leaf-blight.” It frequently causes much damage by injuring the foliage so that the plants are incapable of perfecting a full crop of fruit, even though a full crop has set, or as Thaxter states, it also attacks the fruit stems and hulls, “ cutting off the supply of nourishment from the berries and disfiguring them by the withering of the calyx.” When the spots first appear on the leaves they are of a deep purple color, but later they enlarge and the center becomes gray or nearly white. Portions of the infested leaves frequently assume bright red tints, and when badly diseased finally wither and die. Treatment.— Bordeaux mixture, 1-to-11 formula, used as advo- cated by Hunn in the Annual Report of this Station for 1892, p. 682, gives beneficial results. When setting a new plantation be particular to remove the diseased leaves before taking the plants to the field, or if the plants must be trimmed in the field, the di- seased leaves should not be left where they can communicate the disease to the new foliage as it grows out. The following treat- ment is then suggested : 464 Report oF THE HorTICULTURIST OF THE Spray the newly set plants soon after growth begins and follow with three or four treatments during the season, as seems neces- sary. The following spring, spray just before blossoming and again in from ten days to two weeks. As soon as the fruit is gathered it is generally a good plan to mow off the foliage if badly diseased and burn it if the beds are to be fruited a second season. Should drought follow, the plants may not recover from this treat- ment sufficiently to give a satisfactory crop the following year. Varieties differ greatly in their susceptibility to leaf spot. Con- sequently, one of the best ways to avoid loss from this disease is to plant those varieties which are least subject to it. STRAWBERRY INSECTS. CROWN BORER. (Tyloderma fragariae Riley.) Description.— The adult insect is a dark brown beetle, of the curculio group, measuring about one-sixteenth of an inch in length. The beetles appear in June or July. The eggs are laid on the plant above ground not far from the crown of the root. The eggs hatch into small, white, legless grubs. These grubs burrow down into the crown where they feed until full grown. Pupation takes place within the excavation, the beetles finally escaping about the middle of August. They are unable to fly. There is but one brood annually. Treatment.— The crown borer is most injurious on old beds, and as each plant that becomes infected is eventually doomed, it will usually be most practical to dig up and burn the infested vines. ct i GRUBS. The larve or grubs of the common May beetle and other closely related species, frequently do much injury by feeding on the roots of strawberry plants. The beetles lay their eggs in sod ground. The eggs hatch into white grubs, which feed on the roots of various plants until the New York AGRICULTURAL EXPERIMENT STaTiIon. 465 third year, when they pupate, finally coming from the ground as beetles. Since the grubs live in the ground until the third year after the eggs were laid, it is good practice not to use land for strawberries before the third or fourth year after it was in sod. SAW FLY. (Emphytus maculatus Nort.) This insect is only occasionally injurious in this State. The adult insect is a four-winged fly of the general habits of the cur- rant and raspberry saw flies. The larve feed upon the leaves. There are probably two broods annually, the second brood pass- ing the winter in the ground. The larvee may be killed by spraying the infested plants with hellebore, one ounce to the gallon of water. 30 METEOROLOGICAL RECORD FOR 1899. a a rk ne = TOA © ™ Ga0sas UATOsOROeE 2 HCs4 ag hy nc i en | 26°% 26° T ep el] 660 BET [Titetteeeeceeeet ees ceeeeeeee senses seveeens 9881 06°83 94°0 | 98°T £8°S Ils 0°9 FOP | GPS §9°T 93°1 B10 190 20°L | ° esst 08°33 | 26°0 ToL 49°T AS FFT &8°3 10% 6h'°S §8°0 $9°S 10°% GSisglea|s FSst 68° Se €24°0 $S°T Ors 6G 4h 86°S GLP GPP 89°T $3°0 PPL sro |° §sst aicvarris cog | Be'T 29°0 C8'T 18°% ers | 69'S tI ne “oe ee ent oateemeees|ie + [tetenereeecereeseenreneeererereersenetenseesereeiics BOOT ‘ay “ul ‘uy ‘al “uy ‘ul “ul “ul ‘ay ‘ul ‘ul “ul ‘ul nm I) a aires. 3 § o 4 ec E FS 3 E 5 Ey Berle epee kat lige emer pipe er ter ee. | Berri nee ie oe - lon -. : . a ~ Ez E g E a P 5 5 ‘SUVAA oO o F, io” .

M. TwiTcHeLt, Augusta, Me., at meeting of New York State Breeders’ Association, held in Rochester, N. Y., Dec. 6, 1899. Success in this world is possible only through our ideals. In proportion as the picture in the mind is clear before the artist, manufacturer or builder is it possible for energy and intelligence to be correctly and satisfactorily applied. Out of great concep- tions alone come great results. Every step in the world’s prog- ress has been the outcome of large ideals in the minds of leaders. Sometimes men have stumbled on great truths, but these have been retained only as the conception of their worth and magni- tude has fixed itself in the minds of intelligent leaders. One of the most difficult things for a man to do is to break company with an old practice and establish himself in new lines of work. The tension of years holds firmly and when the thought of change comes and habits are broken, the danger is of drifting, and this is likely to carry to the opposite extreme. Men, espe- cially those who live largely by themselves, get most firmly grounded in their practices and find it very difficult to see the merit of what is clear and open to others. Go back to the first report of this association and note to what a degree the leaders of that day outlined what we are to-day urging, how from that time to the present the one thought of progress, along the lines of present demands, has been the objective point towards which they have sought to urge the people. Ever the truth has been the same, though year by year there has come better and still better appreciation of what that truth was, and how it could best be applied to the needs of humanity. The old time con- ception was sufficient unto its day and generation; the newer is demanded to-day in every field of activity. It is truth just the . . ‘ ‘ Sareea celine ake an 9GZP ‘ON ‘Q1SISHLINS 40 SS3HONG ‘MOD A3YIHSYAY 1HOd3yH WOH “H3LNIHd 31viS ‘NOAT ‘6 S3aWYv? Jupagina CATTLE IN THE SHow-RING. 9 same, but it comes in new dress, it centralizes and focuses on specific points and parts, it divides and subdivides, for the rea- son that as we probe into closer relation of things, we find that, in the perfection of our knowledge of parts alone can we, in any true sense, grasp the perfection of the whole. Have we ever paused to consider, as we should, how completely man may comprehend and control the most intricate problem of commerce, of manufacture, of art and music, and also how the greater his knowledge, the deeper his researches, the more faith- ful his investigations, the more profound will be his apprecia- tion of the mysteries which surround and develop his every step along the pathway of agriculture. More than this are we fully alive to the fact that as we grope, using our best knowledge, we find the way opening for greater and still greater results, results which are all the whilé bringing increasing blessings to the world. We stand amazed at the marvelous, which is made plain to our understanding by the delvers in the realm of nature, yet they are but putting together the fragments, but coming to a realization of the great harmony which exists throughout. They are not changing, but appreciating what is, and seeking to conform to nature’s requirements, out of this knowledge build- ing for the good of future generations. It is simply getting at the harmony of things which alone makes possible improvement. Anything and everything which will aid in strengthening faith in the underlying verities, stimulate ambition to grow, arouse competition along lines which lead to better stock and products, educate towards an appreciation of what must be taken in its entirety in order for the man to be a man in the best sense of the term—all this is demanded in the field of active duties to- day, and will be in all the days before us. Hands are to be but willing servants of active brains The power which lifts the standard of production or rate of. speed brings to the forefront added lines of beauty, and a higher degree of intelligence must have keener appreciation and a clearer ideal. Have we ever thought that it is only in our ideals we are to find safety, and no where else, whether it be in the field of the moral or me- 10 Bureau oF Farmers’ INSTITUTES. chanical. They are at the foundation of advancement. The era of muscle has been superseded by the era of brains. All the conditions of trade conspire and inspire towards a higher stand- ard. Whatever our fancies, practices and natural inclinations, there are outward conditions ruling in all departments of com- merce and manufacture which govern the farmer as well as the tradesman. The farmer is not merely a producer to-day, what- ever he may have been in the past. Out of his manifold forms of improved machinery, by which he is able to increase output, he becomes a manufacturer, and the laws which govern in the realm of manufactures govern in that of agriculture. Not alone profit out of sales, but saving in cost of manufactur- ing, whether it be milk, butter, wool, fruit, farm products or poultry, saving in wastes, saving in labor, both of machine and man—this is what gives success in the shop and mill, and this alone will suffice on the farm. The necessity for constant study of details, close watch on all departments, constant weeding out of the least profitable, seeking for reduction of friction in oper- ating, is appreciated on the one hand, else there could be no successful manufacturers; it must be grasped in its fullness if there is to be satisfaction and permanence on the farm. It is no new thought I am giving utterance to, but simply the presentation of a principle, accepted but not governing, else there would be no call for the discussion of this system of measuring values at our exhibitions. We have reached unnatural conditions in the breeding of all classes of live stock. Functions natural in their origin have been intensified, divided,subdivided and marvelously increased through the ideals of men backed by the dominant will of an objective mind. The exalted position maintained to-day by individuals and herds is not accidental, neither is it permanent. The higher levels are secured and maintained only by persistent application of one’s largest conceptions, the subjective mind yielding surely to the positive influence of the clearly defined ideal in the mind of the master. To-day I plead for this ideal, necessary as never before, in order that the forward steps taken by the seers and Jupeing CATTLE IN THE SHOW-RING. ‘1 prophets in breeding may become the standing ground of the great mass of breeders. Altogether too large a per cent. of our animals, of all breeds, must be stamped purposeless, partly from lack of skilled breeding, but more for want of skilled breeders. The standard of every breed is to be measured by the highest level reached by any individual breeder who seeks to secure and fix the essential qualities recognized by the fancier, ard those also demanded in the actual tests which determine merit. The unmistakable evidence of marked family characteristics only emphasizes the lesson of the hour. Animal life, like clay, yields readily to the hand and eye of the skilled worker, but, as the standard rises, the plastic nature be- comes more positive in its type, as it grafts on the mental con- ceptions of the man at the head. Gentlemen, the day has ar- rived when the true breeder must be reckoned an artist, for un- der his touch he is painting color of hair, skin and membrane, shaping form, developing beauty and perfecting symmetry, while all the time intensifying those organs which alone can in- sure rapid and heavy production or growth. Alongside the great painters and singers are ‘to be placed the seers in breeding, who have founded herds and established families noted not only for breed and type characteristics, but alike for great individual worth as producers. They fill the stalls in every breeding estab- lishment, ‘they are multiplying on every hillside, they are adding wealth to the farm homes of the world, and, more than all, they are waiting to be led out into larger fields of service as men come into clearer appreciation of fundamental principles governing de- velopment. Consciously, or unconsciously, we measure an article, indi- vidual or animal, at the first glance. Why we like or dislike we may not be able to state, but the impression is there, and future examinations seldom change the result. This intuitive perception may be more keen in the minds of some than others, but it is the safeguard of the world. Out of it have come the results of the present in every field. Searching for the why and how, men have been led out into larger conceptions, where ideals have taken 12 Bureau or Farmers’ INSTITUTES. more definite shape. All do not have intuitive perceptions in the same direction, but all do have intuitive perceptions in some direc- tion. In judging, we always measure by our ideal. It is the only safe standard; it is what we would have if we could transform to suit our fancy. No matter what the system, whether in public or private, here is the bar of justice to which the individual animal or product is to be brought. Granting these premises, what is their application to the topic of the hour? Just this, that the method of judging should be that which will be of greatest service to the individual owner and exhibitor in the to-morrows before him. Men may come and go but breeding is to continue, and always along the line of im- provement, simply because our necessities will force us up and on in the study of animal economy and the appreciation of animal machinery. Have we come to the full standard of our ideals; if so there is no future for us, and we are but cumberers of the earth. If not, then is there a call for the bringing out in clear and unmis- takable lines that ideal which we would create and establish, an ideal of form, courage, intelligence, service, and as we reach after and seek to grasp its outlines, they will still float in the upper realm of our consciousness, but the standard we shall attain to will gradually rise toward the ultimate in quantity and quality. It is the natural tendency with men working alone to drift unconsciously into fixedness of habit. The evil attending this is recognized. Out of this condition comes the low standard of pro- duction, the large per cent. of unprofitable stock, the quantity of inferior products, the evidence of a want of appreciation of the best means and methods of marketing—whieh, to-day, is fully one-half the story. Out of this condition comes the opposition to books and newspapers, the feeling that agricultural colleges and experiment stations are fads and not necessities, expensive luxu- ries which may benefit the few but cannot be of service to the many. All this is to my mind perfectly natural, and while we can see a great advance, as we mark the milestones of the past, there is needed a getting down to simple problems and a study of parts in sole relation to the whole, and with the one thought JupGING CATTLE IN THE SHOW-RING. 13 of purpose. When in our examination we take up the evidences of temperament, there is opportunity for close observation in determining fitness for any special service. Between the nervous and phlegmatic there are many shades, and to classify so that each shall have credit calls for skill, the result of practice. Yet it is just this skill which the milk producer or dairyman must have if the weeding process so necessary is to be intelligently applied. : The pathway of human experience is strewn with wrecks where the cold phlegmatic man has attempted to fill the sphere set apart for his nervous neighbor. Large production in our dairy cows is found only in the more highly nervous organisms. If this be balanced by intelligence, then we have the profitable producer. So is it with the driving horse, the egg-producing hen, and there must be some method by which, in our annual fairs, these ele- ments of success may be made clear to the man who has not yet entered into an appreciation of the importance of these relations. The worth of the individual will always settle the question of the worth of the herd, and to bring out the individual characteristics of each one is legitimately within the scope of the score card. We need to fix permanently in mind the fact that form governs purpose and that there is no place in the economy of the closing days of this nineteenth century for a man or an animal which is not built for something specific. So important is it that we must graft this thought into the warp and woof of our being, if we are to stand successfully in the competition of the next twenty-five years. No one opportunity offers such advantages for getting clear and unmistakable evidence of what is demanded to-day as the annual exhibition; but to realize the most, a man must be a competitor and not an indifferent visitor, and the system of awarding premiums one which will furnish the greatest possible amount of information, not only of the strong, but especially the weak points in his animal or product. It is this and this alone which will educate, which will improve and advance. There are valuable animals in every herd. Are they the result of well- directed efforts or are they accidental products? If the latter, 14 Bureau or Farmers’ Institutes. then by a better knowledge of parts we need come into a more complete appreciation of how these accidents came, that well- directed effort may more rapidly increase the individual value of the herd. So the scale of points and score card fit naturally into the daily work of every breeder seeking to improve. The man with the card in hand who is to award the premium may not be as much an expert as the man who holds the halter, but the re- sponsibility is on him to put his estimate on every part in accord- ance with the standard of perfection, and then place his name at the bottom of the card. Few men will show favoritism in such a field. More than this, these cards are the safeguards of the expert, as they furnish the story of his work in detail. In case of errors, the remedy is easily applied and justice done to every exhibitor. Instead of comparing animal with animal and forgetting the points of difference, as must be the case as soon as the class drops out of sight, we have here the full record to be retained for the protection alike of the society and the expert. As we are to consider the subject with reference to competition, the object of competition must be clearly recognized. 1 assume that the mercenary spirit, the winning of a dollar, may properly be set one side, for if it enters it dwarfs and destroys all possi- bility for competition to be of service. The man whose sole pur- pose in exhibiting is to win honors and dollars is not a breeder, but a camp follower. His herd will retrograde inevitably, for his conception is purely selfish, and while selfishness plays no part in the development of a producing herd or animal, it always stands as a bar to progress. Competition for intelligent comparison is educative, and education lifts ideals and broadens vision. For this to be possible the association under which an_ exhibition is held owes to the exhibitors certain specific things: ist. Ample room for protection of stock, and examination of same by the public. 2d. Generous advertising of individual exhibits. 3d. Permanent and ample pens for judging, with seats for inter- ested spectators. JUDGING CATTLE IN THE SHow-RIna. 15 4th. A system of awarding prizes which will insure justice to the individual exhibitor, and at the same time furnish to him and the public the reasons leading to giving or withholding an award. 5th. An expert to award the prizes who shall be required to remain one-half day after the work is completed to meet disap- pointed exhibitors. 6th. A blackboard on which the sectional values shall be placed as given by the expert, where all who desire can follow the work in detail, and be led to question the decisions. Breeders are sharp and shrewd, looking after their own inter- ests, but they are reasonable men all the while, and if they ques- tion an item in the score, the expert, if he be worthy the place, will, by pointing out the defect, satisfy the owner or correct a mistake. The greater the publicity the less cause for criticism after awards are made. If the object be to promote agriculture, stimulate love for better stock, and strengthen purpose to procure the same, then the show ring becomes the one great object lesson of the year, and the system of judging the educating influence. I assume that we have passed out of the old custom of appointing a committee of three, and recognize the certainty that a single judge in a class insures more satisfactory results, providing the full record of his work is secured for the exhibitors. We are discussing animals, not owners, and the awards should be so placed that the cry of favoritism cannot be raised. 3 Two systems of awarding premiums are before us, the compara- tive and the mathematical. The advantages of the former are that the work can be more rapidly performed, the ribbons placed in less time, and expenses reduced. The disadvantages are that no evidence is furnished as to the reasons for giving or withhold- ing, that there can be nothing educative under such methods, and it is impossible to prevent the charge of favoritism. The advantages of the scale of points and score card are not that the awards are placed more equitably, but that the full evi- dence is on record, part by part, a copy to be furnished the exhib- itor, for each animal scored, that the study of parts thus stimu- 16 3UREAU OF Farmers’ INSTITUTES. lated will surely lead to a more equitable balancing of the whole, preventing the natural tendency to over or underestimate, and forcing the conviction that the value of the animal lies in the sum total of the value of the several parts indicated in physical and mental make up. The disadvantages of this system are the difficulty in making equitable mathematical calculations, deter- mining the per cent. of value in each part, and measuring the individualism of the individual, something not easily put on paper, simply because partly intuitive. A perfect system for awarding prizes has not yet been devised. Human intelligence has not yet compassed the whole problem, and certain inequalities must surely be noted; but when the neces- sity for a sharper insight into the worth of parts of the great machine is recognized, and the certainty that a study of parts, and the relation each bears to the others, is sure to stimulate the breeding of still better animals, the possibilities of the score card, both as an educator and promoter of good judgment, must, I believe, be admitted by all. The criticism made that no two judges place the same value on parts has little weight, all the exhibitor at any exhibition can ask being that the expert preserve an equitable ratio of values in placing the awards. If another expert scores higher or lower, it is no argument against the system, it simply speaks of indi- vidual estimates. If on another occasion the figures are changed, it only confirms what has already been indicated. Criticisms of this class are captious, failing in that they belittle the educational feature of the score card while magnifying the arbitrary ruling of that method which furnishes no reason for judgment. If ex- hibits at our fairs are to be maintained, and the number of exhib- itors increased, this question of judging by some system which will return to the individual owner full evidence of the estimate of the expert upon his individual exhibit must be perfected. Under the committee and comparative system the rights of ex- hibitors are altogether too much ignored, the work of judging is hurried, and would-be successful breeders become discouraged and drop out. ; JupGiIne CATTLE IN THE SHOW-RING. oi The exhibitors make possible your exhibitions, and they are entitled to all the evidence in every case where an expert sits in judgment. The responsibility is upon fair managers to provide not only reliable experts, but some system by which the awards may not only be placed in justice, but all the educational benefits possible secured to every exhibitor. In the breeding of to-day utility swings to the front as the chief standard of merit. For this to be secured and perpetuated the importance of careful, painstaking, systematic breeding must be everywhere insisted upon. The standards of growth and pro- duction must be raised next year, and prepotency in transmitting desirable qualities inhere in all our blooded stock in larger degree than ever. For this to be recognized and made positive to the breeder every score card should carry the reasons of the judge for his cut on any part, and so full a description of each section that perfection will be placed above the line of present attainments. The man who can find nothing to change in an animal or product, and so gives perfection on parts, is not an idealist, has no high conception of perfection, and while for the time he may please the vanity of the breeder, his influence is sure to dwarf judgment and lower the standard of excellence. With the fact before us that the sharp competition of the future will necessitate larger output and finer quality in order to secure desired revenue, the obligation falls clearly and sharply upon the breeder to enter into closer sympathy and clearer comprehension of the intelligent machine spending itself for his blessing. There’s a wonderful degree of satisfaction and assistance to be obtained from a close study of cow and horse, hog and hen physiognomy as well as anatomy. Nothing will so rapidly bring a man into close sympathy and fellowship as when he is seeking to come into, and unto, an appreciation of the traits and trends, the thoughts and aspirations, and, more than this, hindrances which make up the forces at work in the animal constitution. We talk about being helped or hindered by our environments, _ but, do we stop to consider the environments of the dairy cow 18 Bureau or Farmers’ Instirutes. from which we are seeking to reap a harvest of gain, or the horse which never falters or fails of the best there is in him. The whole line of production has become so abnormally un- natural that the man at the helm must be in touch with more of the forces at work in the bodily structure of his animals, if he would contro] and increase production, size, rapidity of growth, style, or speed. The measure of each is simply the measure of the man. He is to be master of all, and because of this we touch here, in this study of parts, one of the greatest problems which can confront the breeder or grower. Perfection is and always will be before us. In this fact lies the only incentive for growth and improvement, and it is the weak, not the strong side of our animals which afford opportunity for the higher skill of man to be felt in improvement. Therefore whatever will tend to make a man more critical, more observant, more enthusiastic, more intelligent, is a help and a necessity. Each individual animal and product varies in some point or part peculiar to itself, and it is only in the summing up of the whole that one can decide what is best. One cow is built along the best dairy lines save that a heavy, beefy brisket shows itself, and we wonder why she fails in her milk production at a time when we expect much. There is her weakness as a dairy animal, and the force of some beefy ancestor is felt as the period of lactation in- creases. Another is light in brisket, but while carrying the same dairy form in general, is stout and heavy in neck, and again an obstacle presents itself to check production. Put these two cows before a critical committee, in a field of cows as good as they, in other respects, but better in the two mentioned, and the owners of these two will criticise when the ribbons are distributed. Such weaknesses in confirmation would hardly be carried by members ef a committee day after day, and to give the reasons for the award, a week after the gates closed, would be an impossibility. Give your judge the score card and the record in all future time will tell the story for itself. One or two other points call for discussion. The time will — come when breeders will demand, and societies will grant, more JUDGING CATTLE IN THE SHOW-RING. 19 time to this work of awarding premiums, when we shall see its important bearing upon all progress and by the use of more individual judges be able to take up more effective work. If the object be to educate, then the exhibitor has the right to demand that the greatest possible amount of information be furnished by the men who are to award the ribbons. Money spent in this way will be productive of greater benefit to the state than for the usual] round of amusements. Let the expert, as he goes to his work, take with him a boy and a blackboard, and as he marks up the scores on the cards, let the boy mark up the board. If the scores differ, the questions will be forthcoming, and right here we touch what seems to be ideal work along the line of substan- tial growth. It will require time and patience, but the man who contributes the stock has as good a right to faithful service as any other. Too long these rights have been neglected, because not demanded. Let the fullest discussion be fostered. There will be no awarding to owners in such a field, and the only point of variance will be that of judgment. Here the expert protects him- self and the society by his record. Until the time comes when this is possible, the experts should remain on the grounds at least one-half day after their work is completed, in order that disappointed exhibitors may seek them out and satisfy their wishes for information. On such occasions it is well to bring the animals together and indicate clearly the points of difference and the reasons for the awards. If the horse or cow has a large, coarse ear, a Roman nose, a thin or extremely thick lip, let these be indicated, and their effect upon disposition, which has so much to do with service, made plain. If you find the walls of the abdomen thin and drawn, the muscular develop- ment deficient, let the fact of lack of vitality be made clear to the grower or breeder. Falling back on the proposition that form must govern purpose, and that each and every part bears relation to every other, the force of these homely illustrations must be admitted. But, you say, are these things necessary? Have we not seen good horses with Roman noses or dished faces, straight hocks or 20 Bureau or Farmers’ Instirures. crooked; cows with heavy briskets or meaty shoulders, coarse ears and narrow thighs, which were good producers? Yes; surely we have, but whether they were the exceptions to the rule or not, the day has come when the currents must be controlled, in all our animals, to a larger degree than ever before, and to do this there must be a greater harmony of parts and a more perfect adjust- ment. Like the more intricate machinery necessary for the skilled workmen successfully to compete in the markets, that through reduced friction there may be a greater ratio of speed or, by more equal bearings, less false spots in the fabric, so in the profitable production of stock, or any of the farm products, there is de- manded a better knowledge of the relation each part bears to every other, in order that the per cent. of waste, either in time, food or labor, may be reduced to the minimum and the quality of the output made most favorable for the success of the grower or manufacturer. From beginning to end the thought of business must be engrafted on every step. Admitting that there are prob- lems in the animal economy not yet solved, and surely not to be controlled, may we not with justice claim that the measure of our ignorance is largely in proportion to the measure of our want of appreciation of the underlying principles at the foundation of this paper. I would, if possible, make imperative the necessity for this study of farm products by a scale of points and the use of the score card, for the simple reason that it lies at the root of successful farm husbandry, and the best system to be used in the awarding of premiums at any agricultural fair is the best for the individual to use in the more detailed study of animals and crops at home. The weaknesses of the system will disappear as one gets into sympathy and appreciation with the foundation on which it rests. It makes men more critical, more observant, more attentive to seemingly trivial things, and less likely to be car- ried away by some fancy point, made prominent, but having only a superficial bearing. There is danger that single parts will be magnified until their relation is lost. Thus one will be swept away by the switch of the Jersey, the knee action of the horse, the number of spikes on the comb of the Leghorn, or the beautiful JUDGING CATTLE IN THE SHOW-RING. Ai. color of the fruit. All these are of value, but do not determine worth. They are only fractional parts of a great whole. Another will ask only of production in the dairy cow, the record made by the horse, the weight of the hen, or the number of eggs, and the yield of the tree. These he will declare are essentials and nothing else can be. Is this true? Are we not called to look below the surface and learn more of the ground work on which the animal or tree stands. A friend, one of the large wholesalers, makes it a rule whenever a boy applies for a position first to study the boy and then study his mother. In the right blending of the natural traits and characteristics of the individual with those inherited from his ancestors, we are likely to find greatest excel- lence. Sure it is that along this line alone will progress be made in succeeding generations. Present so-called fancy points must give way for the substantials, and the standard moved up where it will bear solely on the question of merit. Color of tongue or switch, width of stripe, number of spots, or other arbitrary mark- ings, unless they add to the intrinsic worth, must be set one side, and how is this to be so easily determined save by giving to each its true value and allowing the sum total to settle the worth of the whole. The superiority of the scale and score card wili readily be admitted, but I make this plea for more systematic work in awarding premiums and for extended and critical examination by the state, through organized bodies, for two reasons, either of which justify the action: Ist. Because it is necessary in order to establish justice be- tween exhibitors and place awards in accordance with merit. 2d. Because of the imperative necessity for raising the standard of quality in all products. The day has gone, never to return, when we may expect largely increased prices for farm products. The outsweep of trade is touching the uttermost corners, and bringing them into close re- lations with the farms. We do not question to-day whether the onions grew in Egypt or New York so long as the price is not increased. For years we have been approaching this lower range of prices and values. It is one of the conditions of our outreach- 22 Bureau or Farmers’ Institutes, ing civilization, and therefore inevitable. At the same time, in the wisdom which has ordained that man shall earn his bread by the sweat of his brow, it is established that there has been, is, and always will be, two conditions, the only limitations being the skill and intelligence of the individual—one is that of production and the other that of cost of production. The farmer faces these two unknown quantities, and the higher he reaches in output and quality, and the deeper he digs into the mysteries of food nutri- ents and food combinations, the surer and the greater will be his measure of profit, in all the years to come. It will be the putting together of the fragments here and there which will lead to better knowledge and therefore better methods, and again we are forced back upon this business proposition which lies very close at the root of the whole question. Greater skill comes only as the result of keener insight and more knowledge. These are not to be obtained save as one grows into an intimate acquaintance with the laws and conditions governing, seeks patiently to learn their relation to each other and the part each bears to the whole, and out of well-balanced judgment and experience applies this knowl- edge in the daily walks of life. This is the man who will always be master of the situation. The Proper Beef Type. Delivered before the New York State Breeders’ Association, at Rochester, N. Y., by Prof. C. F. Curtiss, Ames, Iowa. I wish to say at the outset that the impression that the success of mastering the great problems in the field of agriculture does not require special preparation and fitness as well as careful study and a high order of ability, is altogether erroneous. The idea that successful farming does not require a trained mind and the highest degree of intelligence, judgment and reason never had any foundation in fact. Robert Bakewell said over a hun- dred years ago that it was easier to find a dozen men fit for cabinet positions than one good judge of live-stock, and the con- ditions haven’t changed very much even to the present day. Has it ever occurred to you that the ability simply to judge stock accurately and well is at least of a rarer kind, if not of a higher order, than that which interprets the laws of a nation. The men who are employed to pass judgment on the live-stock that goes to the great markets of this and other countries, men who are required to know simply one thing and know it thoroughly, command a higher salary than men who preside at the bar of justice in the highest courts of the land. This may seem like a striking statement, but nevertheless its truth is fully attested by the records and salaries paid for these positions; and if you were to hunt the country over, I will guarantee that you would find a hundred per cent. more men competent to serve as judges in the highest courts than are qualified to pass accurately on the real value and utility of live-stock. The men who are em- ployed to do this work at the great market centers are thor- oughly trained experts. They must be able ‘to determine almost at a glance just how much and what kind of a product an ani- 24 Bureau or Farmers’ INSTITUrEs. mal will cut on the block, and the work will permit of no inac- curacy. Their judgment and the training of their mental fac- ulties involve thousands and almost millions of dollars in a single day. Why should not a breeder and feeder have the same discriminating judgment? In other words, why is not the work of breeding, feeding and selecting domestic animals more of an exact science? Simply because of lack of training. To put it in other words and more plainly, men fail to breed good animals primarily because they do not know what they are—because they have wrong conceptions and wrong ideas of standards of excel- lence. A celebrated artist when asked to name the first essen- tial to success in his profession replied “to see right.” So it is in this field; no one ever succeeds without first seeing right. A man can no more attain the highest excellence and skill in agri- culture without a clear mental conception of his object than can an artist produce a great masterpiece without a right conception of what constitutes the highest art. During the closing days of the recent Trans-Mississippi Expo- sition at Omaha, while the stock show was in progress, a very successful shepherd, a man who was a real artist and a master hand at his profession, showed a sheep from his father’s flock in England that was very much admired by all who saw it; a sheep that was a marvel of excellence in all qualities that go to make up a perfect sheep. ‘“ Where was that sheep bred?” in- quired an interested stockman. “Ah,” replied the young man, “that sheep was bred in England before I was born,” meaning by the reply that it had taken fifty years of constant, thought- ful, painstaking and intelligent work to bring that animal to its -present state of perfection. | Good stock does not come by chance nor by haphazard meth- ods. During the Trans-Mississippi Exposition at Omaha, to which I have referred, a students’ live-stock judging contest was held, open to all of the agricultural colleges of the United States. There were seventeen contestants, representing five col- leges. Each student was examined thoroughly on two classes of hogs, two of cattle and two of sheep, and one of the exam- Tue Prorer Beer Type. 25 iners in that contest, a man who was himself a practical, experi- enced stockman, and one of the keenest and most intelligent judges of our country, said that the young men whom he had examined were capable of going into the best herds and flocks of the country and selecting the best animals and giving a sounder and more intelligent reason for sustaining ‘their judg- ment than nine-tenths of the owners or proprietors of these herds and flocks. You may ask why this was the case and why those boys were able to do such creditable work? I reply that it was simply by reason of thorough study and intelligent methods of investigation, by a careful and critical faculty of observing live- stock which comes from analyzing the merits of animals point by point and considering the reasons and their logical results. A brief consideration of the qualities of practical excellence in beef cattle may well engage the attention of the breeder and feeder. A topic of this character is too often regarded as of interest only to the professional exhibitor or the lecture-room instructor and student. But every successful breeder must al- ways be a student, for the first essential in successful breeding is a clear conception of what constitutes a good animal and of all the characteristics that go to make up real excellence in a herd. It is said that the late renowned Amos Cruickshank, the founder of the great Scotch tribe of Shorthorns, was often seen by the side of the leading sale rings of Great Britain intently studying every animal that came into the ring, and his minute knowledge of all the animals shown was the marvel of those who chanced to converse with him about them afterwards. While the methods of the justly celebrated Robert Bakewell, the first great improver of live-stock, were largely secret, it is known that he was not only an exceedingly close student of living forms, but that his rooms were also full of models and parts of domestic animals that he had carefully dissected and preserved for future reference. In his work of selection and improvement he imparted to the Leicester sheep such a remarkable aptitude to take on flesh that this quality remains, even to the present day, a charac- 26 Bureau or Farmers’ InstItTures. teristic of the breed to a greater degree than of any other long- wooled breeds of England. This aptitude to take on flesh is of vital importance to the beef producer as well as the breeder of show-ring and sale stock. The show-ring type must necessarily keep close to and be largely governed by the practical demands imposed by the feed yard and the block, else the lessons of the show yard and sale ring are without value, if not positively misleading. No one is more con- cerned in what constitutes the essential qualities of a good beef animal than the man who breeds and feeds for the block and at- tempts to meet the conditions imposed by the market; for it must be kept in mind that this is the ultimate end of all beef stock, and the best beef animal is the one that carries to the block the high- est excellence and the most profit. This, in a word, is the key- note of the whole problem. The Beef Type. There is at the outset a well-defined beef type that admits of less flexibility than is generally supposed. We hear much about the dairy type—and there is a dairy type, fairly clean cut and well defined—but there is also a beef type, more clearly defined and less variable than the dairy type. Common observation and experience confirm this assertion. There are not a few cows of quite positive beef tendencies capable of making very creditable dairy records, and a great many that combine milk and beef to a profitable degree, but a good carcass of beef from a steer of a pronounced dairy type or breed is rarely seen. So clearly and definitely is this beef type established that to depart from it means to sacrifice beef excellence. The accompanying illustrations (Figs. 1, 2 and 3) pretty accu-. rately represent the ideal beef type. The first is a good repro- duction from a photograph of a prize-winning Angus heifer ex- hibited by Queen Victoria at one of the late Smithfield fat stock shows. The next is a portrait of a high-grade Shorthorn steer, raised as a skim-milk calf at the lowa Experiment Station He was the best steer in the Chicago yards on a day when there were thfield (England) Fat Stock Show Smi ’ 1—Champion Angus Heifer Fig. 4 a wis ‘ 4 ” Fig. 2.—High-grade Shorthorn steer.

The third is of a high-grade Here- ford steer, fed at the Iowa Experiment Station, that was good enough easily to top the market, and was one of a carload to dress an average of 67.5 per cent. of net beef. He weighed 1620 pounds when two years old. These animals, though representing different breeds, present that compactness of form, thickness and substance, together with superior finish and quality, coupled with an inherent aptitude to lay on flesh thickly and evenly, that always characterizes the beef animal of outstanding merit.

This applied to the animals of a ring virtually amounts to the use of a score card without the objectionable features of that system. In recommending the score card to the student, the term “student” is used in its broadest sense, embracing not only the prospective breeder within the class room, but every member of the great practical school as well who wishes to keep in the foremost rank of his profession. It is not necessary here to take up in detail all the points enumerated in the foregoing score card, but it is proper to discuss briefly the controlling principles and logical reasons that govern the formation of a standard of excellence of this nature. The analytical method of resolving every problem into scientific formulas and principles, based on the firm foundation of unques- tionable truth, is the intelligent method of study and investiga- tion, and this method ought more generally to prevail in agri- culture. : Beef Characteristics Briefly Defined. The first thing that should be looked to is the general beef form—low, broad, deep, smooth and even, with parallel lines. No wedge shape or sharp protruding spinal column is wanted for the block. Next in importance is a thick even covering of the right kind of meat in the parts that give high-priced cuts. This is a very important factor in beef cattle that is often overlooked. The accompanying illustration (Fig. 5), represents the wholesale method of cutting beef, showing the relative importance and value of the different parts. In a test made in Chicago on six representative beef animals—two Shorthorns, two Angus, and two Herefords—fed and marketed by the lowa Experiment Sta- tion, the cuts designated as “rib” and “loin” averaged 27.8 per cent. of the aggregate weight of the carcass and sold for 63.9 per cent. of the total value. By this method the chuck, or shoulder, and rib cuts are divided between the fifth and sixth ribs, and in doing so the knife is run close up to the shoulder blade. The rib and loin cuts are divided between the twelfth and thirteenth ribs, and the loin is separated from the “round ” at the point of the 30 Bureau or Farmers’ Instirvures. hip. In cutting for the retail trade the “rib roast ” is taken from the cut designated “rib,” and the “ porterhouse” and “ sirloin ” cuts are taken from the loin cut. Tenderloin steak is taken from the inside and just beneath the ribs on either side of the spinal column, and the commercial beef tenderloin always comes from inferior stock, mainly from “canners.” That class of cattle has no other meat that is desirable for the block, and the tenderloin strips may be pulled out and put on the market, while the re- mainder goes into the boiling vats for canned or pressed beef. To take tenderloin steak from good carcasses would destroy the value of the “ porterhouse” cuts. This the dealer never does. The other retail cuts and their relative values are shown in the second diagram (Fig 6). The third illustration (Fig. 7) represents the retail method of English butchers. The Chicago and New York markets discriminate more sharply and present a wider variation in the relative price of the prime and coarser cuts than any other markets in the world. By refer- ence to the wholesale method of cutting beef used by Swift & Co., and the actual wholesale selling prices of the several cuts taken from a bunch of cattle sold this firm by the Iowa Experiment Station, it will be seen that the rib and loin cuts command over four times the average price paid for the remainder of the carcass, and it is apparent that the practical beef animal must be good in these parts. Broad, well-covered backs and ribs are absolutely necessary to a good carcass of beef, and no other excellencies, however great, will compensate for the lack of this essential. It is necessary to both breed and feed for thickness in these parts. And mere thickness and substance here are not all. Animals~ that are soft and patchy, or hard and rolled on the back, are sure to give defective and objectionable carcasses, even though they are thick, and they also cut up with correspondingly greater waste. A marked and important change has taken place in the profit- able type of cattle within comparatively recent years. This change is strikingly illustrated in the development of the Short- horn. By the courtesy of that veteran feeder and most excellent THe Proper Breer Type. 31 authority on live-stock, the late William Watson, I am permitted to furnish a good illustration (Fig. 8) of the popular type of beef animal about the beginning of the present century. At that time Culley said, in one of his contributions on live stock, that the “unimproved ” breeds of Teesdale were a “ disagreeable kind of cattle, that, though fed ever so long, never produced any fat, either within or without.” Youatt, another celebrated author, described them as “ generally of great size, thinskinned, sleek- haired, bad in handling, coarse in offal, and of delicate constitu- tion.” With this as a foundation stock, it is not so difficult to understand how an animal of the Newbus ox stamp might be classed as belonging to the improved order. This ox was sired by a grandson of Charles Colling’s celebrated bull “Old Favorite,” and the dam was supposed to be a Scotch Highland cow. The early Shorthorns were large and massive. The famous Durham ox weighed nearly 3800 pounds when 10 years old. The demand for early maturity and plump, sappy carcasses of medium weight and minimum offal and waste had not then set in. It was not until within recent years that the heavy, inordinately fat, or rough and patchy bullock, became unpopular to such an extent as practically to drive this class from the market and to banish the type from the breeding herds. It is well that this was done, for the modern type, represented by the first three illustrations, makes beef at decidedly more profit and economy to both the producer and the butcher and furnishes the consumer a far superior article. The parts furnishing the high-priced cuts must be thickly and evenly covered with firm yet mellow flesh of uniform good quality and alike free from hard rolls and blubbery patches. Coarse, harsh and gaudy animals will no longer be tolerated, much less those that are bony’and bare of flesh on the back and ribs. The men who buy our cattle and fix their market value are shrewd enough to know almost at a glance how much and just what kind of meat a steer or carload of steers will cut out, and if the pro- ducer overlooks any of the essential points he is compelled to bear the loss. 32 Bureau or Farmers’ INsTITures. Then, in addition to securing the general beef form and make- up, together with good backs, ribs and loins, there is a certain quality, character, style and finish that constitute an important factor in determining the value of beef cattle. One of the first indications of this is to be found in the skin and coat. A good feeding animal should have a soft, mellow touch and a soft but thick and heavy coat. A harsh, unyielding skin is an indication of a sluggish circulation and low digestive powers. The char- acter and finish exemplified by a clear, prominent yet placid eye, clean-cut features, fine horn and clean, firm bone, all go to indi- cate good feeding quality and a capacity to take on a finish of the highest excellence, and consequently to command top prices. Coarse-boned, rough animals are almost invariably slow feeders and hard to finish properly. A certain amount of size is neces- sary, but it should be obtained without coarseness. The present demand exacts quality and finish rather than size. Beside these qualities, and above all, it is necessary to have vigor and constitution. We find evidence of these in a wide forehead, a prominent brisket, broad chest, well-sprung ribs, full heart girth, and general robust appearance; and without these, other excellence will not have its highest significance. Excellence for the Block Due to Inherited Quality Rather Than Feed or Gain. The misleading practice of rating beef animals mainly by the gains made in the feed yard is altogether too common. The dis- tinction between cattle of different types is absolutely essential to profitable feeding. There is not a very great difference in the rate of gain, or the number of pounds of increase in weight from a given amount of feed, that will be made by a representative of the best beef breeds, or by a genuine scrub, a Jersey or a Holstein steer. This statement may seem somewhat at variance with pre vailing opinion concerning the potency and superiority of im- proved blood. Practical breeders and improvers of live-stock have been rather reluctant to recognize this doctrine, and a good many will not concede it yet, but the evideuce is constantly aeen- —Newbus ox. Fig. 8 Tuer Proper Beer Type. 33 mulating; the principle has been repeatedly demonstrated, and it is useless to ignore facts. After all there is no well-founded reason why a Shorthorn, an Angus, or a Hereford should make more gain in weight from a bushel of corn than a native or scrub. This is governed alto- gether by the digestive and assimilative machinery of the steer. The Holsteins, for instance, are well known to be hardy and ex- tremely vigorous eaters. They consume large quantities of feed, and render good returns for their rations, and the despised scrub has a ravenous appetite, and is almost as omnivorous as a goat. It is not reasonable to expect that the improved breeds, notwith- standing their superiority in other respects, have inherited any greater constitutional vigor or more perfect working organs of digestion than those animals belonging to the class designated as natives, or scrubs, which, from the nature of their surroundings, and the very law of their existence, have been inured to all kinds of hardship. Nature’s law of the survival of the fittest was more rigid and exacting than the selection of the average modern breeder. Why, for instance, should a Shorthorn or a Hereford steer be able to utilize a larger proportion of a given ratior than a Holstein? Has not the latter been as highly improved, as care- fully and as continuously bred for the express purpose of making good return for a liberal ration? Scientists have discovered that civilized man has no greater powers of digestion than the bar- barian or the Indian. Neither has the improved steer materially better digestion than the native. The feeder is often deceived in the belief that he has a good bunch of cattle simply because they feed well and gain rapidly. Economy of production is an important factor, but it is by no means all. It is even more important to have a finished product that the market wants and will pay for than it is that it should simply be produced cheaply. The illustration (Fig. 11) represents a high grade Jersey steer, fed and marketed by the Iowa Agricultural Experiment Station. This steer was fattened and finished for market under conditions quite similar to those of the Shorthorn and Hereford steers pre- viously spoken of, and the rations were practically the same. 34. Bureau or Farmers’ Insrirures. The Types Compared. In making a comparison, only the Hereford will be used, but the distinctions are equally applicable to either. While in the feed lot the Jersey made a gain of 2 pounds a day for nine months and the Hereford 2.03 pounds a day for fourteen months. There was practically no difference in the rate and cost of gain. Judged by the record they made up to the time they went to market, the Jersey would take rank close to the Hereford in both rate and economy of gain. But the interesting part of the comparison came later. The Jersey took on flesh rapidly and was exceedingly fat and well finished. He was as good as it is possible to make a Jersey steer. Yet, when he went to market he had to sell $2.123 below the top quotations, while the Hereford was one of a car- load to sell 10 cents above the top for any other cattle on the market. It is sometimes claimed that this distinction is partly due to prejudice, but since I have followed cattle through the feed lot and to market and onto the block, carefully ascertaining all the facts for several years, I am convinced that the expert buyers who fix the price for beef cattle in the great market cenires rate them strictly on their merits, entirely independent of any breed or type consideration. The controlling factor is the utility and inherent value of the animal for the practical test of the butcher. The slaughter and block test clearly revealed the reasons for this marked distinction in the selling value of these two steers. The Jersey belongs to a breed that has been developed for cen- turies for the specific purpose of making butter; that is, putting the product of its feed into the milk pail. They are rough, an- gular and bony, and when fattened they do not put the fat into the 'tissues of the high-priced cuts of steaks and roasts on their back, as a representative of the beef breed does, but this steer had 190 pounds of what is termed loose, or internal, tallow and 55 pounds of suet on a 763-pound carcass; that is 32.1 per cent. of the steer’s carcass was tallow. Tallow was at that time worth 4 cents a pound, while the best loin cuts were worth 19 cents at wholesale. And beside that, this steer only dressed 57.5 per cent. of beef, while the Hereford dressed 67.5 per cent. Then, Tuer Proprer Beer Type. 35 the Hereford had only 95 pounds of tallow and 38 pounds of suet on an 888-pound carcass, equivalent to 15 per cent. And beside this striking difference in the percentage of meat in the high- priced cuts, the meat of the Jersey was much inferior to that of the Hereford. The Jersey steer went on accumulating fat around his paunch and internal organs to the extent of nearly one-third of his entire body weight, while he did not have meat enough on his back decently to cover his bones. This explains why a Jersey or a Holstein, or any other animal not expressly bred for beef, can never be made plump and smooth, no matter how long it is fed or how highly it may be fattened. Besides, what scanty flesh that is there will be found of inferior quality owing to the absence of that fat deposited throughout the tissues of the meat that is necessary to a ripe, juicy and highly flavored cut. There is a fundamental and essential reason why rough cattle do not sell. These same distinctions are largely true of the native and all other unimproved cattle when an attempt is made to fatten them for beef. The men who buy them are well aware of these distinctions and they fix their market values accordingly. It is of vital importance, then, that the feeder should have the right kind of cattle for fattening. The Jersey and the Hereford steers previously referred to made practically the same gains in the feed lot and at substantially the same cost per pound for feed consumed, but the market comparison revealed the fact that the steer of beef type and inherited beef-making capacity was making a product worth 49 per cent. more than the other steer, and this increased value not only applied to the gain made in the feed yard, but to the entire carcass as well. The feeder cannot afford to ignore these distinctions. They are of vital concern and deter- mine profit or loss. If the producer were hauling his corn or other products to market, instead of feeding it to cattle, he would not hesitate to select one that would return 49, or 25, or even 10 per cent. more than another. The loss cannot be afforded in either way. Growing Potatoes Successfully in New York. By D668 LeERRy, Farmers who have nearby markets can grow potatoes almost any way and get along. Those who raise this crop to ship to mar- ket, or to sell to shippers, have to manage carefully to make any- thing in the future. The former sell to the consumers, or to the retail grocers. They get almost all there is in the business. The latter have to pay commissions and profits to dealers and freight to railroads. Potatoes are now grown by the hundred acres on a single farm in Aroostook county, Maine, in Michigan, Wisconsin, Minnesota, Kansas, etc., etc. Many of these growers have rich land and great, clean fields, without obstruction. Large shippers get rebates from the railroads, at any rate they can get their potatoes, hundreds of car-loads, moved long distances for very little money comparatively. Machinery is used on these great fields to produce the crop as cheaply as possible. Growers of potatoes for shipping, in New York, have to meet this competition. A few years ago they did not. High freight rates prevented the moving of potatoes long distances. But all this is changed. It will require the best methods in the future to make money grow- ing potatoes, on the average. Cheap Fertility. The large growers above named, except in Maine, are not pur- chasing plant food to any extent. They have enough in their soils, or at least they get along with what they have. Aroostook county, Maine, has used large quantities of fertilizers for potatoes; but the writer was there some years ago, talking to large audi- ences and telling them they ought to grow clover in regular rota- tion and reduce the fertilizer bill. Reports from there show they Growine Potrators SuccressFuLLY In New York. 37 are working in to this way of producing the crop cheaply. The climate favors these Maine farmers, and many in the other north- ern States named. It is easy to grow large crops. Fertilizers may pay New York farmers well, but they cost money. To com- pete with the northern world they must get fertility for less money. They must pay more attention to growing clover and peas in regular rotation with potatoes and other crops. A heavy crop of clover grown once in four years may get hundreds of pounds of nitrogen out of the air and make it available for pota- toes, corn, etc., that follow. You cannot afford to pay $15 or $20 a hundred pounds for this when you can manage to get it for nothing. The clover will pump up plant food from the subsoil, also, and leave that available. The big western growers are get- ting hold of this matter. The writer has talked to many of them in Minnesota, where they are growing clover and increasing their crops; so much the worse for you if you do not do the same. Many of the northern growers have made the serious mistake of growing potatoes either continuously, or too frequently, on the same land. Do not do this. You will soon have serious trouble from scale, blight, rot, etc., which multiply and increase more rapidly where the crop is continuously grown. And then more plant food must be purchased under this method of management. Do not grow potatoes oftener than once in three years on the same land. The writer has followed for many years a three-year rota- tion of clover, potatoes and wheat. These were early potatoes, so we were able to get them off in time to put in fall wheat. With late potatoes, oats or spring wheat could be substituted. This rotation is all right for a few years, but a four-year one would be safer in the long run. We have grown clover pretty often; we may have trouble from this. Scientific men think we may. But meanwhile we have made a nice sum of money growing potatoes that feed on the plant food the clover obtained. We have not purchased fertilizers. And still few, probably, have done any better than we have with this crop, and our land was in poor shape to start with. If you care to grow corn, I advise this rotation: Clover, corn, potatoes and small grain to seed with. Manure the clover sod for 38 SUREAU OF Farmers’ INSTITUTES. corn. Keep stock enough to eat the clover, and corn, oats and some purchased food, and use the straw for bedding. Save all the manure, liquid and solid; not sort of half way, but actually all of it. That is the way we do. Have cement floors under all live- stock, manure shed, etc. These last points are of great import- ance to you. I'll tell you why. The large western farmer won’t get to this point for some years to come. You get right at it and you can increase your crop, in connection with other good meth- cds, so as to compete with him. You may say you can’t make the clover grow now. But you must. Where there is a will there is away. I saw on an old “ worn out” (?) farm in Vermont, last. summer, as fine clover as ever grew on earth, many acres of it, on the farm of C. F. Smith. This man’s neighbors said clover would not grow. Well, Mr. S. made it. You can. With him it came from the use of lime and potash, and an increase of vegetable matter in the soil to decay, and persistent sticking to it. The clover grew better and better each time it came around in the rotation. In the northern part of the State you may grow good feed and increase fertility by raising field peas, in connection with oats, to hold them up. I do not need to tell you that hay made from peas, oats and clover, nicely cured and early cut, is worth nearly as much again per ton as timothy for cows, young growing animals, sheep, etc. You get this in addition to the fertility. The Best Tillage. One can hardly expect the western farmer, with his great fields, to be very thorough in his tillage. The tendency there is to get an income from the number of acres, rather than from ‘the yield per acre. Here is a chance for the New York farmer. ‘Till thor- oughly from beginning to end. Do the best that is known now along this line. There are probably fifteen or twenty tons of nitrogen, phosphoric acid and potash in one acre of your potato land, within one foot of the surface. But it is locked up by nature and only a very little becomes unlocked and available for crops each year, with ordinary tillage. More tillage of the right kind will make more of it available. This will be particularly true when you supply your soil with plenty of vegetable matter to de Growine Potrators SuccEessFuLLY In New York. 39 cay in it by growing heavy crops of clover, manuring, plowing in catch crops, ete. Work the seed bed more. Work it deeply. Work it roughly, that is, throw it around a good deal and mix it up. Make it fine, where it is clayey enough to form lumps. Do all working when it is rather dry. Cultivate the crop many times; keep stirring the ground, as long as you can get a horse through it. Go as deeply as you can for a week or ten days after you can see the rows, and then after that never more than two inches deep. Before your potatoes (and corn) are six inches high the roots come together between the rows. If you tear any of them off, as you will if you go more than two inches deep, the plants must grow them over again. In a dry time this means serious loss, in particular. You do not need to stop this kind of culture at blossoming time; it can do no harm and usually will do much good. Look on the potato field as a summer fellow that you will work about all summer, and grow potatoes while you are doing it. You may make much plant food available in this way, not only for the potatoes but for other crops following. In the spring there is usually plenty of water in the soil and subsoil. If you do not do your part a good proportion of this may be taken up into the air by sun and wind, and wasted. Two inches of freshly-stirred, fine soil makes almost as good mulch as afoot of straw. Keep this earth mulch present from the moment the ground is dry enough to harrow, in the spring, until the potato crop is grown, as nearly as is practical. In connection with the vegetable matter mentioned above in the soil, to hold water, your tillage may make you a fair crop, almost without re- gard to rainfall. In stirring the ground to make more plant food available, do the work also at just the right time to form a mulch and check evaporation. Never let the surface dry up hard after arain. You can use a smoothing harrow until the crop gets up; then a weeder is better, after the tops are too large for the weeder, and also in connection with weeder use one-horse cultivators, with many small teeth. We have planted four inches deep and then did not hill up any, at least not more than an inch or two. Some earth will be thrown to the rows. Remember that weeds take a great quantity of water out of the soil. To grow a ton of 40 Bureau or Farmers’ Instrirures. dried weeds on an acre would mean the loss by evaporation through the leaves into the air of some 300 to 400 tons of water. Often the potatoes seriously need the water. Don’t let the weeds use it up. Keep the surface so constantly stirred with smooth- ing harrow, weeder and cultivator that no weeds practically can ever see day light; then they will be killed as they sprout in the soil. Do you think the large western grower will give careful atten- tion to all these points? Well, I am afraid not, usually. Itisa grand chance for you to get ahead of him. ‘Till thoroughly to help feed your crop, and to water it. This is no idle tale; no theory. The writer has made thousands and thousands of dollars by putting into practice for many years all that is written here. He has grown large crops without fertilizer, over and over again. He has grown large crops ($100 to $160 per acre), almost without rain, right in the midst of failure. In the worst seasons he has cleared a hundred dollars an acre on potatoes over all cost, and furnished neighbors with what they wanted to eat, although they planted in the spring, and on just such land as his. Man can do almost anything, and he believes in doing it and making success come. Other Pointers Briefly Outlined. Above you have a foundation that is solid and good. One can not enter into the small details of the business in a brief article like this. It would require a book. But I will try to give you a few important pointers. The western man drives about five horses, that draw a wide disk harrow, and leads three more that are following with a smoothing harrow, across his long fields. Change your fields so as to make them as long as you can and get large tools and drive more than two horses. If you are going to grow potatoes to sell to shippers, or to ship yourself, grow enough to amount to something; enough so that you can afford the best labor-saving tools on the market. The Robins planter is the best one made. The Hoover digger is almost perfect, under any reasonable circumstances. I say this after riding on it many seasons. We use four horses to draw it. Of course being all iron it is not fit to dig soft, green potatoes. We have found it well Growine Potators SuccEssFULLY In New York. 41 to use potato boxes for handling the crop, by the hundred. They are 16x13x13 inches inside, with hand holes in the ends and made of very light wood. They hold one bushel (60 pounds) even full; thus one can be placed on another. Find out what varieties of potatoes do best on your soil and in your climate and then stick to them as long as they do well, and select the best for seed each year. Don’t grow more than one or two kinds. Straight goods sell far better than mixed. Keep your seed so that no sprouts will start until after the potatoes are in the ground, for main crop. The first sprout gives the strongest plant. You can sprout a few in the light for early ones. Do not apply fresh manure on land for potatoes. Put it on at least the fall before hand. In the four-year rotation named (clover, corn, potatoes and small grain), the manure applied to the clover sod for corn will be in excellent condition for the potatoes the following year. Treat all seed to destroy scab germs that may be on it, thus hold- ing this trouble in check as far as you can. If you grow potatoes with nearly level culture (always the best way in a dry season, and as good in a wet one on drained land), plant in drills. If you plant in hills, you must hill up or they will grow out of ground and crack ground open and be injured in quality. If you want potatoes perfect in quality (snowy white inside), never let them be exposed to any light at all from the time they set until you eat them, so far as is possible. Keep them where it is absolutely dark. Those who sell to consumers or to local retail dealers may well make a note of this point; and also it will pay them to grow only those varieties that are choice to eat.. Much of our money was made in this way. I have sold 1,000 bushels of potatoes to a grocer in the city at one time for 15 cents a bushel above market price. First, I produced something choice, way above the ordi- nary, and then I let folks know what I had. After trying them and finding that they could depend on their being No. 1, always, they readily paid me my price. Fertilizing Self-Sterile Grapes. By. Prof. S. A. BEACH. Not long ago a letter was received at the Geneva Experiment Station from a grape grower near Seneca Lake, in which the writer says: “T have some Wyomings and they don’t bear well, and I have been grafting some of ‘them with other varieties. They make good, strong, healthy stock to graft on. I want to get a few of some good early varieties. Is the Croton a good bearer? Does it cluster well? Do you know anything of the Alexander Win- ter, its color, quality or any other particulars? ” Such inquiries serve as a very good introduction to the sub- ject—“ Fertilizing Self-Sterile Grapes.” Similar questions in one form or another may rise in any com- munity where American grapes are cultivated. Although they may vary in detail, sometimes one variety causing disappoint- ment and sometimes another, they are frequently similar in their primary significance in that the fundamental cause of their trouble lies in the inability of the variety properly to fertilize itself. Such is the case with the Wyoming, which this corres- pondent is grafting over to other kinds. The Wyoming usually fails to set any fruit, unless it is fertilized by some other ya- riety, as does also the Alexander Winter referred to. These are in this particular, representative of a large class of American grapes, many of which rank very high in flavor and quality, and when well-formed clusters can be produced are remarkably at- tractive in appearance, but unable to fertilize themselves they are unreliable croppers, unless cross-fertilized with some other variety. The Croton, to which our correspondent refers, on the other hand, produces well-filled clusters without the aid of any other variety. In this respect it is representative of another large class, including many of the varieties which have proved most generally successful in commercial vineyards. FerrTitizInG SELF-STERILE GRAPES. 43 A year ago the State Agricultural Experiment Station at Geneva, N. Y., published Bulletin No. 157 on the “ Self-fertility of the Grape,” in which each of the 169 cultivated American varieties was classified according to its ability to set fruit of itself. The following pages from this bulletin contain the classi- fied lists just mentioned: In this classification the varieties are arranged in four classes, accord- ing to the average character of the clusters which have developed from covered blossoms on vines in apparently normal condition. In cases where there is doubt as to whether the vine was in proper condition for the test the name is followed by a question mark, to indicate that the classification is doubtful. Class 1 includes varieties which when self-fertilized have formed none but perfect clusters, and those with which the clusters have varied from perfect to somewhat loose. Class 2 includes varieties which when self-fertilized have on the average formed marketable, although not compact, clusters. Class 8 includes varieties which when self-fertilized have on the average produced clusters too loose to be marketable. This class has a wide range. It extends from the varieties in Class 2, with clusters not too loose to be marketable, to Class 4 which includes the self-sterile sorts. There are varieties in this class which have on the average produced self- fertilized clusters nearly compact enough to be marketable, some being compact but others being loose. At the lower limits of the class are found varieties which usually fail to produce fruit on covered clusters but, which have occasionally borne a few scattering fruits when the clusters are covered. aes Class 4 includes those varieties which have not produced any fruit on covered clusters.

These investigations have a practical bearing both on the selection of varieties and on their arrangement when planted. The self-sterile kinds cannot be expected to set fruit when they stand alone. Plate 1 shows what was left of covered Eumelan clusters at the time the fruit ripened on the uncovered clusters. It is seen that not a fruit developed when the Eumelan was compelled to depend on itself for setting fruit. Herbert and Barry likewise fail to fruit when dependent on their own blossoms for pollination. Brighton does a little better. The best results which its covered clusters gave in these investigations are the three clusters shown in Plate II. But self-sterile varieties may produce well-formed clusters when located near enough to other kinds of grapes so that cross polli- nation can occur. The clusters of Herbert and Barry, shown in Plates VI and VII, and that of Brighton, shown in Plate III, were borne on vines which were located favorably for cross pollination. The varieties which are listed in Class 3 have generally developed clusters imperfectly filled and unmarketable and those named in Class 4 have failed to develop any fruit whenever cross pollination has been pre- vented. If these varieties are planted at all they should be set close to other varieties, which bloom at the same time, so as to provide for cross pollination. The varieties which are named in Classes 1 and 2 produce well-formed clusters of themselves. The covered clusters of Duchess and Diamond, illustrated in Plates IV and V, show what perfect clusters may develop on varieties in these classes when the blossoms are self-pollinated. The va- rieties named in Classes 1 and 2 may therefore be planted alone without reference to cross pollination. Explanation of Plates. Plate I. Eumelan self-fertilized. Plate II. Brighton self-fertilized. z Plate III. Brighton open to cross pollination (reduced one-third). Plate IV. Diamond self-fertilized (reduced one-third). Plate V. Duchess self-fertilized (reduced nearly one-third). Plate VI. Herbert (reduced nearly one-half). Plate VII. Barry (reduced nearly one-half). After Bulletin 157 was issued, inquiries came to the station from various sources, bringing up the question whether one kind of grape was any better fertilizer for the self-sterile kinds than another, or whether all that was necessary to provide for the proper fertilizing of a self-sterile kind was simply to plant next to it a variety which came into bloom with it. For the purpose 46 Bureau or Farmers’ Instirures. of gaining some information on this subject investigations were begun which, in 1899, included tests in fertilizing 12 nearly or quite self-sterile kinds with pollen of various varieties, some of which were self-sterile. Methods of Making Tests. All clusters were covered with bags before thé blossoms opened, to keep away the insects, which might otherwise visit the flowers and bring with them the pollen of other varieties. This was done with the clusters which were to receive the pollen and with those which were to furnish the pollen also. When the clusters were in bloom the bags were opened and the blos- soms brushed with clusters taken from the variety which had been chosen to furnish the pollen for that particular test. The bag was then immediately closed and properly labeled. It was left undisturbed till after the vines had gone out of bloom, after which the results of the tests were recorded. When the fruit was ripe it was gathered and each cluster rated on the scale of 100, to show how well filled it was with fruit, 100 repre- senting a perfectly formed cluster. Some of the results are summarized briefly in the following paragraphs: Aminia is practically self-sterile. When it was used to pol- linate Brighton the clusters averaged 0.3 on a scale of 100 for a perfect cluster. When used to pollinate Wyoming the average rating was 2. This indicates that Aminia is practically worth- less as a fertilizer for self-sterile sorts. When Brighton and Wyoming were pollinated with strongly self-fertile kinds like Catawba and Niagara, good clusters of fruit were produced. Black Eagle, as far as tested, has proved self-sterile. It was used to pollinate the self-sterile Barry and the practically self-sterile Eumelan, but no fruit resulted. Brighton is practically self- sterile, but occasionally it produces a few fruits when self-pollin- ated. (See Plate II.) It was used to pollinate the follow- ing varieties which are self-sterile, or nearly so (the average Fertinizing Setr-STertLe Grapes. 47 rating in each case follows the name of the variety): Aminia, 1.7; Black Eagle, 0; Eldorado, 0; Herbert, 0; Lindley, 4; Merrimack, 8.8; Salem, 0; Wyoming, 12. Catawba has proved to be strongly self-fertile in the tests of its self-fertility which I have made. It was used to pollinate the following varieties, which are self-sterile or nearly so (the average rating follows the name of the variety): Aminia, 89; Brighton, 74.4 and 80; Eldorado, 0.5; Herbert, 100; Lindley, 63; Merrimack, 91.7; Salem, 4; Wyoming, 100. Herbert is self-sterile. When it was used to pollinate the self-sterile Eldo- rado and Salem, no fruit was produced. When used on the nearly self-sterile Brighton the average rating was 28. Lindley, so far as tested, has proved self-sterile. It was used to pollinate the following kinds, which are self-sterile, or nearly so (the average rating in each case following the name): Brighton, 2; Eldorado, 0; Herbert, 0; Merrimack, 32; Salem, 0.4. Merrimack is self- sterile. When used to pollinate the self-sterile Lindley, Herbert and Salem, no fruit resulted. When used on the partly se!f-sterile Brighton, all clusters but one failed to fruit, and that was well filled. This test should be verified by further work. Niagara is strongly self-sterile. It was used to pollinate the following varie- ties, which are self-sterile, or nearly so (the average rating after each name): Aminia, 80; Brighton, 85.7 and 52.5; Eldorado, 76; Herbert, 98.8; Lindley, 77; Merrimack, 96.3; Salem, 98. Without giving further particulars, it will be sufficient to say that without other tests which were made the results in general were similar to those which have been given. The use of self- sterile, or practically self-sterile, grapes for fertilizers for other self-sterile, or nearly self-sterile kinds, resulted in failure. When varieties which are strongly self-sterile, like Catawba, Niagara and Worden, were used to pollinate these self-sterile sorts, gener- ally good clusters of grapes resulted. In conclusion, a word of caution as to the significance of the average ratings which have been given in the above account of these investigations. They cannot be taken as showing accurately the ability of the variety to fertilize the other varieties upon which 45 Bureau or Farmers’ Instirures. its pollen was tried, because the clusters were not always in full bloom when pollinating was done. Nevertheless, in a general way, the results may be taken as signifying that self-sterile sorts are practically worthless as fertilizers for other self-sterile varie- ties, and that it is best to select as fertilizers for s.lf-sterile grapes strongly self-fertile kinds which bloom at the right season. For a more complete account of these investigations consult Bulletin 169 of the State Experiment Station, Geneva, N. Y. Some Practical Points in Bean-Growing. By J. E. Witson, Linwood, N. Y. Beans seem more particular in requirements of soil and climate than most farm crops. The area devoted to cultivation is quite limited, western New York and Michigan furnishing the greater part of the domestic crop. Their cultivation has necessarily been developed in the field by practical experience, and methods here outlined are employed by our most successful bean-growers. Beans do best on rather heavy soil if well drained, naturally or otherwise. They are very sensitive to an excess of water in the ground. Good corn land will grow good beans, generally. They will not thrive on light or sandy soils unless well manured. A clover sod makes the best seed bed. A corn stubble manured the year previous for corn, or an old sod, fall plowed, will give good results. They pay well for stable manure, especially if applied the fall or winter before on sod. Plow the ground in spring as soon as dry enough to work mellow, usually the early part of May with us, plowing deep, eight to ten inches, if the soil will admit of it, and do a thorough job, as careless plow- ing will materially reduce yield. As soon as plowed, ground is rolled and thoroughly fitted, and then worked over about once a week until planting time. It should be cultivated twice or more, during this time, with a large-toothed cultivator, working it from four to six inches deep. This deep working by large- toothed implements, thoroughly stirring the soil and bringing new particles together, seems to bring about some chemical ac- tion, which, while it may not be understood, has proved beneficial. If it is a dry spring, only shallow working should be given for a few days previous to planting, that the moisture may rise near 50 Bureau or Farmers’ Instirures. enough the surface to germinate seed. This thorough working for a month or six weeks will make a mellow and moderately firm seed bed to the depth of four or five inches, will liberate a large amount of plant food and destroy most of the weed seed. The time of planting will depend somewhat on the variety grown. The Marrow pea, perhaps more largely grown than any other, is planted anywhere from May 25th to June 20th, usually about June 10th or 12th. The Marrow, Yellow Eye, Red Kidney and others of the larger varieties, are planted a week or ten days earlier. About three pecks of pea beans, and from four to five pecks of the large varieties, per acre are planted in drills twenty- eight inches apart. Most growers use common grain drills for this purpose, stopping the hoes not needed. Care must be taken . not to get the seed too deep; if the ground is in good condition, vne inch is plenty deep. If they do not come up quickly they will not make a full crop. If your soil responds to fertilizers, an ap- plication of from 100 to 250 pound of a mineral fertilizer will increase the yield and help ripen the crop evenly and earlier—two — important points. A few days after planting, and before beans come up, go over ground with weeder. This breaks all crust, destroys what weeds may have sprouted and levels ground, so that crop can be culti- vated sooner. Just as soon as they are large enough, the culti- vator and weeder is started, cutting as close to the row as pos- sible, the first time with the cultivator. The weeder is used in connection with the cultivator as long as practicable, going over the beens once a week or every ten days until ripe, or until vines fill the row. After first time over, cultivation should not be over an inch or inch and a half deep and ground kept as near level as possible. With proper points for the cultivator this can be very easily done. In raising a crop of beans it must be borne in mind that they make their entire growth in about three months, and that in the dryest and hottest part of the year, and in ordinary seasons, a large part of the moisture which they need will have to be held in the ground from the spring rain. Hence, the necessity of early Some Practicat Pornts 1x Bran-Growina. 51 and deep plowing and the thorough preparation of the soil before planting, as a deep, thoroughly-prepared soil will hold more moisture than a shallow and cloddy one. Frequent cultivating breaks any crust and checks evaporation, leaving most of the moisture for the use of the plant. In plowing deep and culti- vating shallow you give the largest amount of root room for the plant, giving them every chance to produce a full crop. As soon as pods are ripe, and before dry enough to shell, they are harvested by a machine made especially for this purpose. Two knives, running about an inch below the surface, pull the beans by the roots, two rows at a time, the knives set at proper angle, to bring rows together. They are then thrown into bunches with forks to cure, two or three of the double rows being thrown into one, leaving room to drive a wagon to haul to barn. They are mostly threshed by a machine built for the purpose, somewhat similar to our grain threshers and requiring the same power to run it. Where only small lots are raised, they are often tread out on the barn floor by horses, in frosty weather. Produce deal- ers take them as they come from the machine and run them through screens, after which they are picked over by hand, and stones, earth and damaged beans removed. Dealers buy them by the bushel (62 pounds) and deduct five cents for each pound wasted in picking. This is often a serious shrinkage to the grower. The price paid here (Linwood, N. Y.) for hand-picked beans is about 35 cents below New York quotations. Beans grown as above outlined, on soil adapted to them, in a favorable year ought to make a crop of 18 to 20 bushels per acre, although this is considerably above average. They pay as well, perhaps, on an average as other common farm crops. The fodder makes excellent feed for live-stock; sheep, especially, are very fond of it and will thrive better on it than on hay. Twelve Years Experience in Spraying. By EpwARD VAN ALSTYNE, Kinderhook, N. Y. The question is often asked, “ What is the use of all this spray- ing?” Is it necessary? A few years ago we heard nothing of these various insects and diseases. Is it a notion gotten up by the people who have something to sell, makers of spraying appara- tus or dealers in chemicals? Are these new troubles? I answer by saying that most of these troubles are not new. We have been increasing our plantings of fruit trees and plants, and have thus - furnished excellent food, as well as good breeding ground, for vari- ous pests, something more suited to their needs, as well as more plentiful than-the wild plants, on which they originally subsisted. Fruit plantations multiply; so do these troubles. As we increase traffic with the whole world we continue to bring in new pests and diseases. Dr. Howard says that of the 75 insects most injurious to fruits, 37 are of foreign origin. Cold, hard facts, but we may as well accept them first as last. He who will not adapt himself to these changed conditions will surely be left in the rear of the pro- cession of progressive fruit-growers. The man who will control conditions is the man who will be paid for fruit-growing as never before. I do not entertain the foolish idea that spraying is the only thing necessary to make fruit-growing successful. Spraying will rot fertilize or cultivate the soil, or prune trees. You have com- menced at the wrong end if you think spraying is all that is neces- sary. If I must choose between spraying, fertilizing and cultivat- ing, I shall abandon spraying, and cultivate and fertilize. If growers think they can starve trees by lack of fertility and cultiva- tion, and once in three or four years cut out the summer’s firewood from the trees, and call it pruning, and then go to work and spray - Twetve Years’ ExperRieNcE IN SPRAYING. 53 and expect satisfactory results, they will be sadly disappointed, and, as many have done before, condemn spraying. After we have fertilized, cultivated and pruned, if we want perfect fruit and greatest success, we must spray, and spray thoroughly and intelli- gently. I want to emphasize the foregoing facts. Twelve years ago I was convinced, after giving my orchard the best care that I could, that insects and disease were increasing, and when first I heard spraying talked of, I thought it, as many have since, a great disaster, and felt that I might as well quit the business first as last. In the fall of 1886 I sold my winter apples for $2.25 per barrel, net, for first-class fruit. After careful picking and grad- ing we had 100 barrels of rejected apples on account of worms and seab. There were about 25 barrels of windfalls beside, out of 300 barrels shipped to market. If they had been perfect they would have brought over $250, and they were worth $25 or $30 for cider. I reasoned that if spraying would do what people said it would, it was certainly a good thing for me to try. I found that it would rot only keep fruit free from worms and scab, but would greatly lessen the number of windfalls. The first year’s spraying is often disappointing. Many start in to spray with very little knowledge of what they are spraying for, or how to do the work. They do not do the work at the right time, nor thoroughly, and they are fight- ing insects and diseases that are well established; hence failure to accomplish what was expected. Diseases and insects multiply year after year, and we certainly cannot expect to destroy them by one year’s work. Insects do not start out to commit suicide for our benefit, and will not eat the poisoned leaves if they can get those that are free from it. Therefore, all the foliage must be covered and kept so, if we expect good results. The man who gets best results from spraying is the one who sprays annually, at the right time and for a definite purpose, covering the whole tree with the mixture. I would not spray a tree that had no fruit on it as inany times as one that was bearing, but I would spray it once or more, for insect and disease germs are there and must be held in check, less they multiply. 54 Bureau or Farmers’ Insrirures. The man who sprays as indicated need fear no new leaf-eating insects or disease that Bordeaux will prevent. I asked a friend of mine in Orleans county if he did not dread the canker-worm get- ting into his orchard, as it was all through the orchards in that section. I have heard Prof. Bailey say that he could actually hear them eat. He replied: “ My trees are annually covered with poison, and I have no fear of the canker-worm.” That was several years ago, and his orchard is as free from canker-worms as it was then. I have seen the time when we took 47 large nests ef the tent caterpillar from a single tree. For five years I have not had to remove a nest from my large orchards where we have sprayed, while a young one not in bearing and never sprayed we had to go through twice last summer and remove the nests by hand. Why? Because a thorough system of spraying had held them in check and destroyed them. Spraying is working by faith, which is a great deal harder than working by sight. Here is a little fungus, or insect, so small that few here have ever seen it. We have to take some one’s word for what it is, where it is, and what will destroy it. To him who has never sprayed I say, don’t do it unless you are thoroughly per- suaded in your own mind that it is the proper thing to do. Then know what particular object you are going to spray, the life-his- tory of the insect, or nature of the disease, with what or how can you prevent or destroy it. I believe that only to the man who se acts will success in this direction come. To illustrate, take the scab fungi. One scientific man says that ihey are so small they cannot be seen with the naked eye, but are present in our orchards in a latent state, ready to develop under favorable conditions, such as high temperature and moist atmos- phere, during which they spread and multiply with enormous rapidity. Bordeaux mixture applied over the whole tree will pre- vent their spread, as the fungi cannot live when they come in con- tact with the mixture. This means the trunk, limbs, twigs, leaves and fruit. Simply to throw a little combination of water, vitriol, lime and poison at the tree after the fungus has spread, will do but little good, while properly made and applied it will not only TweLvE YEARS’ EXPERIENCE IN SPRAYING. 55 give us clean, bright fruit, but a vigorous growth of healthy foli- age, which means more fruit, a stronger tree and fruit that will keep much longer than that from a tree with poor foliage. This I have found more than once. After years of experience with the Bordeaux mixture I have come to regard it almost with veneration, and had I to choose be- tween it and insecticides I should without hesitation select Bor- deaux. Its value depends largely on its being properly made. Dr. Sturgis has given us much valuable information along this line, and I would advise a study of the bulletin on this subject issued by the Vermont Experiment Station. I have not time to go into detail, only to say that by putting six pounds of vitriol with half of 50 gallons of water, and four pounds of lime with the other half, and then combining these two weak solutions, will give a mixture that will stay in suspension and not clog the muzzle and will spread easily and remain long on the trees. We always dissolve the vitriol and lime before hand, using as many gallons of water as we have pounds of material. A gallon then represents a pound and all figuring is done away with. The insect that causes the most trouble is probably the wala moth, and while the egg may hatch anywhere on the fruit, it usually enters from the blossom end. If we spray just after the blossoms fall and the fruit stands upright the poison will be col- lected on the tops at the blossom end, is likely to be retained there for a long time, and pretty sure to be fatal to the worm before it enters the apple. This period when the apple is in this position with the petals open, may be longer or shorter according to the season, and varies with different varieties. It will be readily seen that each of us must watch his own orchard and the different varieties therein to know the proper time to apply the poison to get the most benefit. There is a prevailing notion that the tree can be best sprayed when it is in full blossom. From the above it should be evident how false this is. Certainly nothing can be gained and much lost by spraying at this time. In addition, it will poison the bees, so necessary for proper pollen distribution. No one has any more 56 Bureau or Farmers’ INSTITures. right to destroy his neighbor’s bees than his cattle. Instances are on record of the bees carrying the poison into the hives. Do not think that I consider spraying an easy job. There is nothing connected with fruit-growing I dislike so much. When I have reached the end of the spraying season and put away the sprayer, I always feel like singing a Glory Halleluiah. It is not an easy thing to do, but it pays, and that is what we grow fruit for. We want profit as well as fun. “ How many times and when do you spray your apple trees?” Usually three times. First, just as the foliage starts, using Bordeaux and Paris green. I find this just as good as to spray earlier. Then after the blossoms fall, as noted above, and usually once more, about two weeks later, using Borbeaux and Paris green twice each. Last year I did not spray but twice. It was a dry season and the spray was retained on the trees, having little rain to wash it off. I have Bordeaux on my trees now (February) that was put on last May. Then, too, we had but little weather to develop fungi. Some years it may be necessary to spray four or five times. I use with Bordeaux mixture, half a pound of green or poison to 50 gallons of water; that is for apples and pears. With a good agitator I have never had it burn the foliage. It will take as much as this to kill the bud-moth and will kill tent caterpillars and other insects quicker, which is an item when a rain follows shortly after spraying. I believe green arsenoid just as valuable as Paris green, and certainly much cheaper. It could be bought last season for 14 cents per pound. For those who are doing much work, white arsenic will be found cheaper still. This needs to be boiled with sal-soda, and while not a difficult job, a beginner had better use the green, as the simpler he can make the operation the better. I find a good deal of the first spraying can be done best from the center of the trees. This I learned from spraying large elms - for the elm-leaf nets. We put a pair of telegraph lineman’s spurs on a man and sent him into a 50 or 60 foot tree with 40 feet of hose and 8 foot rod. Ordinarily a good, powerful hand pump, with a good agitator, will do the most practical and thorough TwELVE YEARS’ EXPERIENCE IN SPRAYING. 57 work. Half-way spraying leaves plenty of uncovered foliage and fruit for insects and fungi to feed on. When the work is thor- oughly done there is no choice for the insect but to eat and die. From 85 to 90 per cent. of fruit may be made absolutely perfect if the work is properly done. To show the advantages brought about by the Bordeaux in giving vigorous foliage, I will site you an instance that happened a few years ago. My men ran out of Bordeaux in spraying the Greening trees, and as they were only short half a barrel, I told them to finish with green and water. The next spraying I helped to do myself, and came first to the side of the Greenings that the men had sprayed last. I at once noticed that the foliage was yellow and sickly looking, and as I had forgotten about the lack of Bordeaux I was planning to give them some increased fertility, but on coming back to the other side found the foliage as healthy as any in the orchard. Then I remembered that those were the trees, one side of which had no Bordeaux, showing the value of the Bordeaux where it is applied, and only there. Now an illustration for the scab on fruit. I have a block of Newtown pippin trees standing below a hill, on rather heavy soil and too close together. These were thoroughly sprayed with Bordeaux three times and poison to test the value of the Bordeaux for the scab. I had in the same orchard three trees of the same variety on high ground in the outside row where they had plenty of light and air. All conditions most favorable to the develop- ment of the scab. These I left unsprayed. In spite of their favorable conditions two-thirds of the apples were so scabby as to be worthless, while the trees unfavorably located, but sprayed, looked as fair as oranges, and pronounced by the buyer the best he had ever seen. One more illustration to show the effect in ridding fruit of in- sects. A few years ago I had strawberries in one orchard, and as the weather was very wet when we should have sprayed, the work was delayed. Fearing to injure the berries the orchard was left unsprayed. I sold my fruit that year, guaranteeing it perfect. That from the sprayed orchard sorted out only one 58 Bureau or Farmers’ InstiruTrss. barrel out of eleven (and those were good seconds that brought $1.50 per barrel) that were not absolutely perfect, while the un- sprayed orchard, only separated from the other by a picket fence, yielded only two barrels out of three that could go under the guarantee. Besides, the ground was covered with windfalls, and in the first orchard hardly any had fallen. : I therefore conclude that spraying pays if done intelligently at the right time, and thoroughly, and if not done this way it had better not be attempted. Injurious Insects and How to Control Them. By E. P. Fett, D. Sc., State Entomologist, New York State Museum, Uni- versity of the State of New York. Before considering any of the forms which so frequently at- tract our notice through their depredations, I will mention briefly some of the beneficial species. Beneficial insects——There are many parasitic and predaceous forms which prey on injurious insects and are therefore beneficial. Examples of these may be found in the numerous ichneumon flies, some of which are important parasites, or in the predaceous ground beetles, bugs and others which boldly attack our pests. A little observation will soon enable the farmer to recognize these and he will then protect or at least avoid destroying them. Pro- fessor Kellogg, of California, records an instance where a well meaning correspondent destroyed a pint of beneficial lady bugs under the impression that he was killing the depredators on his rose bushes. Other species feed on noxious plants and thus in- directly benefit man by preventing these from becoming nuis- ances. Insects also render valuable aid as scavengers and the myriad forms inhabiting the soil undoubtedly do much toward reducing it to a more friable, fertile condition. They are also used to some extent for food by man and the honey bee supplies a most important article for the table. Insects are also fed to poultry, song birds and in nature undoubtedly constitute a valu- able food for many fish. The silk worm supplies the material for an important fabric, the cochineal and lac insects, substances of considerable value in the arts. One of the most important ben- eficial functions of insects consists in fertilizing the blossoms of our fruit trees, that is, carrying the pollen from flower to flower. Without the aid of bees, wasps, certain flies and other insects, it 60 Bureau or Farmers’ Institutes. would be impossible to obtain a full set of fruit without resorting to artificial fertilization. The enormous labor involved in this is easily understood and when we think of the number of trees and other plants that would have to be gone over and the relatively short time in which the work must be accomplished, our depend- ence upon insects is apparent. This emphasizes the wisdom of not spraying trees while in blossom. The spray wets the flowers, thus preventing the insects from working for a time, the poison used is apt to burn the tender parts of the flower, rendering fer- tilization impossible, and finally the bees themselves may be poisoned by visiting sprayed blossoms. They may even carry the poison home, kill the brood and contaminate the honey. There is also a state law prohibiting spraying trees while in bloom. So far as controlling insects is concerned, everything necessary can be accomplished by applications made either before or after blossoming time. Losses caused by insects—Many persons fail to realize the enormous losses caused by insects. The annual loss in the United States has been estimated at $400,000,000. Dr. C. H. Fernald, State Entomologist of Massachusetts, considers a loss through insect ravages of 10 per cent. of the value of a crop a conservative estimate. On this basis, the loss on cereals, potatoes and hay grown in New York State in 1898 would amount in round nnm- bers to $7,000,000. Professor Slingerland, of Cornell University, estimates that the codling moth causes an annual loss in New York State of $2,500,000 on the apple crop and $500,000 on the pear crop, making a total for this insect of $3,000,000. An im- portant point to remember in this connection is, that of 73 species regarded as of prime economic importance, that is each causing annually in the United States losses running into the hundreds of thousands of dollars, 37 are known to have been introduced, and the original home of six is still open to question. We may not be able to exclude insects from the country at large or from the state, but the individual farmer has it largely in his power to prevent certain species from obtaining a foothold on his farm. An orchard is grown not for the fruit it produces the year after it is | Ingurious Insects anp How to Contrrot THEM. 61 set out, but for the crops ten to twenty-five years later; conse- quently it should always be some distance from the boundary lines, so that the owner may never be obliged to suffer throngo the carelessness or indifference of a neighbor. All trees and plants brought on a farm should be closely scrutinized and it would be a wise precaution to fumigate all such with hydrocyanic acid gas (as recommended on a following page) or else to buy only stock which has been so treated. If these precautions are taken, a man may reasonably expect to reap nearly full benefit from his efforts to keep his orchards free from injurious insects. Number of injurious insects—The number of injurious insects is so great that it is impossible to treat of all those worthy of notice. For example, 378 different species have already been listed as preying in some manner or other on the apple tree or its fruit, and while the majority of these can hardly be regarded injurious, as a rule, yet under unusually favorable circumstances almost any one of them might cause considerable damage. Before passing to the consideration of individual species, there are a few funda- mental facts which should be emphasized. Biting and sucking insects—In a practical way we must dis- tinguish between those insects which bite off and devour por- tions of their food and others which obtain their sustenance by sucking fluids from the underlying tissues. The work of the former class may easily be recognized by portions of a plant being eaten away. Asa general rule such insects can be controlled by spraying with an arsenical preparation, provided the poison is placed where the insect must eat it or go hungry, and the suc- cess of the operation will be proportional to the plant surface covered. In short, when spraying with arsenical poisons aim to have the insecticide hit every: portion of the plant liable to attack. The necessity of this is shown by the following: Last spring maple leaves were sprayed with several arsenical preparations. The variously treated leaves (after the spray had dried and the poison was therefore nearly invisible,) and some untreated ones were placed in separate jars and forest tent caterpillars placed 62 Bureau or Farmers’ Instrrrures. with each lot. In spite of these precautions, the caterpillars on the sprayed foliage ate very little for from twelve to thirty-six hours while those on the untreated leaves fed most readily. The Same results were repeatedly noticed with the elm leaf beetle. The more successful fruit-growers make a practice of spraying every year; first as the buds are opening, second, just after the petals have fallen and before the green calyx lobes have closed, and then about seven to ten days later. Such treatment should be amply sufficient to control all orchard pests which yield to arsenical poisons. If four ounces of Paris green or other arsenical preparation is added to fifty gallons of Bordeaux mixture, we have a very effective fungicide and insecticide combined, which is of special value for the first treatment. If spraying is under- taken, it most certainly should be continued year after year, be- cause experience has demonstrated that it is far from wise to await the appearance of a pest in force before applying the remedy. As the arsenites lie in small particles on the surface of the plant, it is evident that an insect drawing nourishment through a slender, thread-like beak or proboscis from the interior of the plant, would be unaffected by such poisons. We must therefore fight sucking insects by using substances which will kill when thrown on the insect. That is, use a contact insecticide like kerosene emulsion, whale oil soap solution, etc. Suecess with contact in- secticides is proportional to the number of insects hit. Spray to cover the pests with the substance. Contact insecticides are to be used whenever insect injury is accompanied by a wilting or discoloring of the affected parts and there is no tissue eaten away. The foregoing are general rules which must frequently be modi- fied to meet special cases. Beware of frauds.—A word of warning in this connection may not be out of place. Beware of remedies for which great claims of one kind or another are made. . There are now forty-six ento- mologists in the United States giving a large proportion of their time to the study of insects and methods of controlling them, and unless a remedy is advised by a well known authority, it will be Jas.B.lLron Srate Printer. »__ Apple Tree Tent Caterpillar Insurious Insects anp How tro Contrro.t THEM. 63 well to go slow before trying it. One of the oldest fakes is plug- ging trees with sulphur or some other substance said to be taken up by the sap, thus rendering the foliage distasteful to insect pests. Such claims have no foundation and should not be heeded. Yet in 1896 or thereabout, as stated to me by Mr. E. Van Alstyne, such an agent appeared in Kinderhook, N. Y., charged two dollars for plugging a tree, took in about $50 and then de- parted, leaving an unpaid board bill. Insect changes.—The farmer should also have some general knowledge of the transformations of insects in order that he may recognize both friends and foes in their various stages. All in- sects develop from eggs of one form or another, though in some cases the eggs hatch within the body of the parent. The larva is the active, growing form, and is the stage more frequently de- structive. It is variously known as the caterpillar, grub, maggot, “worm,” etc. The pupa is the quiescent, resting stage, during which the transformation from the comparatively simple cater- pilar to the highly organized butterfly or moth takes place. These changes will be more fully emphasized in the following accounts of certain injurious species: Apple tree tent caterpillar.—This insect, Clisiocampa americana, yearly causes much damage in spite of the fact that its habits are well known and methods of suppressing it are understood. It passes the winter in the egg. The brownish egg mass encircling a twig is represented at figure 1 on plate 1. The young cater- pillars may be found well developed within the egg in the fall and emerge therefrom in early spring. They remain in clusters under the familiar tent, feeding on adjacent foliage, and by the time they are half grown, we have the well-known condition represented at figure 3, plate 1. The caterpillars become full grown (plate 1, figure 2) the latter part of May, and at that time may be seen wandering in all directions, seeking a place for spinning their cocoons, several of which are represented at figure 6, plate 1, and one still more enlarged at figure 4. The co- coons are spun in early June and may be found in almost any 64 Bureau or Farmers’ Lystirures. convenient crevice, affording some shelter from the elements. The pinkish brown moths, plate 1, figure 5, appear from the latter part of June into July, pair and deposit the eggs which produce caterpillars another season. It is comparatively easy to collect and destroy the egg clusters, as most of them are on the lower limbs. If the orchard is sys- tematically sprayed, even this is unnecessary. The creatures can also be destroyed when collected in their nests, either by tearing the nests out and crushing, or by burning. The latter is hardly advisable on account of injury to the tree. Forest tent caterpillar—A closely related insect and one which attracted far more attention last summer is shown on the next plate. It is variously known as the forest tent caterpillar or maple worm, scientifically as Clisiocampa disstria, and is a close relative of the preceding form. Like it, the winter is passed by the well-developed caterpillar within the egg. The smaller, shorter, lighter colored egg belt is represented at figure 1, plate 2. The eggs are frequently found in large numbers on small sugar maples, if there be any in the vicinity. On moderate-sized trees, a large proportion are found on twigs within twenty or thirty feet of the ground, while on large trees it is not unusual to find them in considerable numbers at a greater height. The caterpillars begin to emerge from the eggs with the advent of warm weather in the spring and continue to appear for about a month. The first evidence of infestation, if the eggs have not | been previously noticed, is a thinning of the upper leaves. The young caterpillars may be found in clusters on the branches, and as they increase in size the clusters are found lower and lower, till, when nearly full grown, large patches may be found on the trunks of the infested trees. It will be seen by comparing fig- ures 2 on plates 1 and 2, that the forest tent caterpillar is char- acterized by the possession of a row of somewhat diamond- shaped silvery spots down the middle of the back, while the apple tree tent caterpillar has a narrow dorsal line of the same color. The forest insect does not form a tent in the crotches of the limbs, a habit so characteristic of the species usually found C.5.Ba nks, del. Jas.B.Lron Stare Printer. Ingzurious Insects AND How to Controut THEM. 65 on apple trees. The full-grown caterpillars wander in search of a place to spin cocoons about the first of June, spinning up about the middle of that month, but some may be found the latter part of June and even in early July, so irregular is their development. The cocoons, as frequently spun in a leaf, are represented at figure 4, plate 2. They may also be found under ledges of houses, in fence corners and almost any convenient shelter. The moths may be taken from the latter part of June into August, being most abundant in early July. Pairing takes place at this time, and the eggs are deposited for the next year’s generation. As is well known, this species has a special fondness for sugar ma- ples, and has caused much injury to the sugar bush of this and the adjoining State of Vermont. The effect attacks by this in- sect have is shown by the following: Mr. Tremain Bloodgood, of Hensonville, Greene county, found that maples defoliated in 1897 and ’98 yielded in 1898 and ’99 one-half the usual amount > of sap, and that more of it was required to make one pound of sugar, though the quality of the latter was not affected. Mr. Jared Tiffany, of East Jewett, found that the largest and best maples suffered most, and that two or three defoliations kill a tree or render it practically worthless, as the flow of sap is very small and the little secured is almost unfit for use. Professor Perkins, entomologist of the Agricultural Experiment Station of Vermont, reports that the crop was not one-half or two-thirds the usual amount in his State, and that the yield was light even in localities where the tent caterpillar was not abundant. In most places it is hardly probable that the pest will be abundant for more than three or four years in succession. Value of native birds—The cause leading to the outbreak of this native species is interesting and worthy of some attention. The pest is undoubtedly controlled to some extent by climatic conditions, and insect parasites are also valuable aids in keeping it in subjection. Unfortunately, we can not control climate, and there is not much that is practicable in the way of encouraging or protecting parasites. It is believed that the native birds are 3 6G Bureau or Farmers’ INSrirures. important aids in keeping this insect in control. Mr. E. H. For- bush, ornithologist to the Massachusetts State Board of Agri- culture, has kindly supplied me with the following list of native birds observed feeding on forest tent caterpillars: Oriole, black- billed cuckoo, yellow-billed cuckoo, crow, blue jay, redstart, nuthatch, wood thrush, chewink, black and white creeper, red- eyed vireo, flicker and scarlet tanager. Mr. V. H. Lowe has ob- served the black-capped chickadee feeding on the eggs and the robin on the caterpillars, beside others mentioned. Professor C. M. Weed states that the robin, chipping sparrow, yellow bird and English sparrow feed on the moths. In view of the fact that our best authorities have estimated that bird life in New York State has decreased 48 per cent. in the past fifteen years, it seems reasonable to attribute this outbreak by forest tent cat- erpillars in part to the decline in the number of birds. The foi- lowing accounts illustrate the value of our feathered friends: In a typical orchard at Medford, Mass., Mr. Forbush took a little trouble to attract the native birds, the nests of the English or house sparrow being destroyed. The results were greatly in favor of protecting our indigenous forms. In the neighboring orchards it was evident that canker worms and tent caterpillars were abundant, but in the orchard in question the trees were seriously injured in only one or two instances, though no at- tempt was made to control the insects by spraying or other arti- ficial means. The following note relating to forest tent cater- pillars is by Miss Caroline G. Soule: “The nuthatches would stand by a patch of larve lying close together below a tar band on a tree and eat so voraciously and with such an entire aban- donment of self-consciousness that I could go close and put my hand on them before they would fly. This experience was re- peated several times.” Our native birds are undoubtedly of great value and will richly repay any slight effort that may be made for the purpose of at- tracting them to a neighborhood. Winter birds may be induced to remain in a locality by hanging in the trees pieces of meat or partially picked bones, and will spend much time in searching Car Banks del Jas.

Migratory birds may be induced to remain in larger numbers in a locality by providing them with suitable nesting places and materials, and by affording them protection from cats and other enemies, not excepting man. Thickets in the vicinity will afford shelter for certain species, and if a few mulberry trees are set out their fruit will serve to protect the cherries, as the birds are said to eat mulberries by preference. Most of these suggestions are taken from a very practical paper by Mr. For- bush. Remedies for forest tent caterpillar—tThere is little that can be done to prevent the ravages of this insect in forests and large sugar bushes, aside from protecting birds, but in orchards, on shade and other of the more valuable trees it is practicable to fight this insect in the egg, caterpillar and cocoon stages. During the winter and early spring the lower twigs bearing egg clusters should be cut off and burned. Every egg mass thus destroyed means approximately 200 less caterpillars to fight the coming spring. As soon as the pests cluster in the trees, they should be brushed down or dislodged with a torch. The latter method is hardly advisable on account of the danger of injuring the tree. Many caterpillars can be jarred from the limbs. In whatever way they are gotten out of the tree, bands should be employed to pre- -yent the caterpillars from ascending. A strip of cotton batting tied tightly around its middle to the trunk and the upper portion turned back over the string makes a very effective barrier so long as it remains dry. Bands of tar, grease, equal parts of lard and sulphur, ete., are very effective in preventing the creatures from climbing the trees, once they have been gotten out. If these latter substances are used, it will be safer to first put on a band of thick paper and apply the grease or tar to it, thus avoiding danger of ultimate injury to the bark. Wherever the caterpillars are at all abundant, it will probably be necessary to kill those collecting below the bands with hot water, kerosene emulsion or by crushing. These insects yield readily to arsenical poisons, G8 Bureau or Farmers’ Insrrrures. particularly if the application is timely, but conditions are not always such that spraying is practicable. Sometimes when the caterpillars are present in very large numbers and the poison has not been applied till late, the trees may be stripped in spite of the insecticide, but under ordinary conditions there need be little fear of the poison proving ineffective. Where spraying is not done, it will probably be wise to supplement the destruction of eggs and caterpillars by collecting and burning the cocoons. The village of Glens Falls, and several others, paid school children 10 cents per quart for collecting the cocoons in 1899, and excellent results were obtained. At Glens Falls 1350 quarts of cocoons were destroyed. Whenever this is done to any great extent, it would be well to put the cocoons in boxes covered with a wire netting, about 3-16 inch mesh, so as to allow the smaller parasites to escape and yet to confine the moths. When the caterpillars are present in large numbers nothing but the most vigorous meas- ures will prevent severe injuries to the infested trees. Codling moth.—One of the most important orchard insects to- day is the common codling moth or apple worm, Carpocapsa pomonella. The wormy apple, well represented at figure 1, on plate 3, is familiar to most of us. Were we to go into the orchard in winter and look under partly loosened bark scales, we would find a condition very much as represented at figure 2, on plate 3. Under the loose bark there is a silken cocoon and within it a partly curled, whitish worm or caterpillar, which is represented much larger at figure 1, plate 4. The winter is passed in this condition. In the spring the transformation to the pupa occurs and about the time the apple trees blossom, the moths (plate 3, figures 3, 4) come forth. About a week later the eggs are laid on the leaves or sides of the young fruit and in about two weeks from blossoming the young caterpillar or apple worm emerges from the egg and usually enters the fruit at the blossom end. This habit renders the control of the pest by spraying comparatively easy, provided it is done thoroughly and at the right time. Any time after the white petals have fallen and before the green calyx lobes have closed is the proper time to spray for this pest. Figure 3 on ———_______ ae bp pcs eA) fo) ne eels (ok ; aNy Ng ile Tima Jas-B.Lvon Stare Printer. C.5.Banks,del. M Codlin Ingurious Insects anp How to Controt THEM. 69 plate 4 shows the calyx lobes open and in the right condition for spraying and figure 4 the condition when the calyx lobes have closed and the impossibility of throwing the poison where it will be most effective. It may be well to delay spraying a few days after the blossoms have fallen so as to reduce to a minimum the danger of having the poison washed out of the blossom cup by rains, but delay beyond a certain period is dangerous because the calyx lobes in most varieties of apples close in about two weeks after the petals fall and then it is too late to do effective work against this insect. Ample time allowance should be made, as the spraying may be hindered by bad weather. The spray should be rather coarse because then it fills the calyx cup more readily. There is practically no danger in spraying young apples with arsenical poisons. Those who do not or can not resort to spraying must depend on the destruction of the infested fruit shortly after it falls. One correspondent found comparative immunity from this pest by allowing hogs to run under his apple trees. Sheep or other do- mestic animals could be utilized in the same manner to good ad- vantage in certain cases. As the apple worms leave the fruit when full grown and spin cocoons under shelters on the trunks, banding the trees and destroying the cocoons found underneath aids materially in reducing the numbers of this pest. Scrape the trunk smooth and apply a band of cheap paper, burlap or similar material in June. These bands should be examined every ten days till August and then once in the fall, destroying all found under the shelter. As many of the pests are liable to be carried into the fruit cellar, it is always wise to prevent the escape of the moths in the spring by covering all openings with fine wire net- ting. “ Sugar maple borer.—The sugar maples in many villages show most serious injury by the sugar maple borer, Plagionotus speciosus. This insect is specially dangerous because the large, white, fleshy grubs thrive in healthy trees and have the pernicious habit of running their large burrows through the inner bark and sap wood. As many of these burrows have a transverse, oblique 70 Bureau or Farmers’ InstiruTes. direction for a part of their course, it is by no means uncommon to see trees partly girdled through the activity of this borer. I have seen maples fifteen and eighteen inches in diameter half girdled by a single burrow. It is ap- parent to all that only a few such borers are necessary to cause con- siderable injury. The beautiful par- ent beetle, represented at figure 1, is rarely seen, but evidences of the in- sect’s work are very apparent. The large, white, fleshy grub or borer is not often observed. It is a most in- sidious worker and probably the best method of controlling it on shade beetle (origiual).

About the best that can be done is to keep the elms in a vigorous condition and cut and burn all affected limbs. Elm leaf beetle—In the Hudson river valley there is another elm pest of considerable importance, and as it will soon make its way to other sections of the State, it is worthy of a brief notice in this connection. I refer to the elm leaf beetle, Galerucella luteola, an insect which has killed thousands of elms in the state and one that in all probability will cause much greater loss in the next decade. It has already been reported as present at Oswego and Rochester, and may occur at many other places in west- ern New York. The yellowish, black striped beetles about one-fourth of an inch long pass the winter in houses, sheds, crevices in trunks and similar shelters. In the early spring they come forth, fly to the trees and begin feeding on the unfolding leaves. Clusters of three to over 20 yellowish eggs are deposited on the under surface of the leaves throughout May, the young hatching about the first of Fic. 3 Elm leaf beetle, mpleti i i 2 adult jreqced from eetle, June, and completing their growth in 15 or 20 ard, U. S. dep’t agr., Year- book 1895). days. There are two broods annually in Albany and vicinity. The beetles eat irregu- lar holes in the foliage and the grubs feed exclusively on the under surface; hence in order to poison both forms, it is imperative that the leaves be sprayed from the under side. Where spraying with poison is not done, some relief may be obtained by killing the golden yellow pup with hot water, kerosene emulsion, etc., after they have collected in large numbers about the base of the tree. This latter means can be made more effective by scraping the rough bark from the tree and then constructing an inclosure a few inches high around the base of the tree. Killing the insects once in five days will give the best results with the least labor. Several very important scale insects are represented at figure 4 and every fruit grower should become familiar with their general appearance. 72 Bureau or Farmers’ INSrTIirures. Old fruit enemies.—Apple tree bark louse, Mytilaspis pomorum. The general form of the brown scale of this insect is nicely shown at a in figure 4 and were we to examine infested trees in winter we would find under the old scales large numbers of tiny white eggs. The scurfy bark louse, Chionaspis furfurus, is represented at b in figure 4. The common name is descriptive of the white, of cane; ¢ English oyster scale; Futuam’s ceale (original), scurfy condition of badly-infested trees. On breaking away the protecting scale in winter numbers of purplish eggs may be found occupying the scale cavity. The winter is passed by both species in the egg stage. About June 1st the young appear and may be seen crawling in large numbers over the trunk and limbs of the infested trees. Either of these scale insects can be kept under control by spraying the young with a contact insecticide like whale oil soap solution, kerosene emulsion, the formulas for which are given at the close of this article. San José scale-—The most important pest represented in figure 4 is this species, Aspidiotus perniciosus. Figure 4¢ represents the female scale and at d the male scale is shown. Observe the round- ness of the ash-gray scale, the central nipple and the lighter ring surrounding it. The adult female scales are frequently consider- ably larger and of a yellowish white color. The scale covering these insects is quite variable, and it requires considerable experi- ence to enable one to distinguish with surety between this species and certain closely related forms and even then the entomologist frequently prefers to take the trouble to make a mount for the microscope and study the insect itself before passing on the iden- tity of the species. A closely related form is Aspidiotus ancylus Insunrious Insects anp How to Controt THEM. 13 » cr Putnam’s scale. It is represented at figure 4f. It can be separated at once from the San José scale by the eccentricity and the yellow or reddish color of the nipple. There is another species, Aspidiotus ostrewformis (figure 4e), which resembles the San José scale very closely indeed. If trees are infested by scale insects or even present a suspicious appearance, it is by all means advisable to cut off a small twig and submit the same to some entomologist for examination. The San José scale is dangerous on account of its inconspicuousness and also because of its great prolificacy. A tree may be nearly covered by this scale and noth- ing be suspected. I have known such to be the case, even when a bright and intelligent man and his two boys had endeavored to keep posted and had been looking for the creature. Careful studies have shown that in the latitude of Washington, D. C., four and even five generations could be produced in a year and that the descendants from one female might in one season reach the enor- mous estimate of 3,216,080,400 individuals. In New York state not over three generations annually would probably be the rule, but even with our climatic conditions the insect is able to keep up with a rapidly growing apple tree, as is shown by a twig fifteen inches long of 1898 growth being nearly covered with the scale at the end of that season. Very diverse opinions are held regarding this insect and its destructiveness. It is at least a pest no man cares for and it is much easier to exclude it from the farm than to maintain a per- petual warfare to keep it in subjection. There are many sections in the state where this pest has not become established and thou- sands of farmers and horticulturists are in a position to prevent the San José scale from gaining a foothold in their orchards. To every such person I would say, buy only trees that have been fumigated with hydrocyanic acid gas or else fumigate every tree and shrub before it is set out. This measure is not only our most practical method of safeguarding against the introduction of the San José scale but is equally valuable against many other im- ported insects. The importance of this latter has already been emphasized. Nothing but the most heroic measures will stamp out the pest after it has become established and these will be TA Bureau or Farmers’ Insrirures. successful only in places where the infestation is very limited. If but few trees are infested and there is no danger of its being in nearby localities, it would be far wiser promptly to destroy everything bearing the scale and start anew, rather than at- tempt to save the trees. An infestation of considerable extent can hardly be fought otherwise than by repeated treatments with contact insecticides. Whale oil soap has proved about as effec- tual as any, though the mechanical kerosene emulsion has been strongly endorsed by some. Perhaps the most promising treat- ment is found in the use of a 20-per-cent. mechanical emulsion of crude petroleum applied in early spring before the buds start. There is no doubt of its killing a large proportion of the scales. There is less danger to the fruit buds if winter treatment be de- layed till early spring and if crude petroleum emulsion be used, the viscid residue remains sometimes on the limbs and trunk and is very unfavorable to the establishment of young scales. Crude petroleum cannot be applied to leaves but it is said to injure only growing wood, even in summer. Its use undiluted cannot be recommended at present. The summer treatment with other contact insecticides consists of several sprayings from when the young begin to appear, sometime in June, till late fall. The fre- quency of the spraying should depend largely on the abundance of the young. The summer work is usually supplemental to the winter operations. The formulas of contact insecticides for either summer or winter use are given on a subsequent page. The following catalogue, descriptive of the insects in a small traveling collection of the more important species, was prepared by the State Entomologist and published in a convenient pocket form for distribution at farmers’ institutes: Fruit Tree Insects. 1 Apple tree tent caterpillar (Clisiocampa americana).

Treatment: handpicking; spray with poison. 26 White flower cricket (Oecanthus niveus). Series of punctures in twigs of various kinds are made by this insect for the reception of its eggs. Injury is usually too little to call for remedial measures, specially as the insects are predaceous and therefore beneficial. Shade Tree Pests. 27 White marked tussock moth (Notolophus leucostigma). Beautiful eat- erpillars haying three black plumes, four yellow or white tufts, a coral red head, and body marked with black and yellow; defoliate horse chestnut, elm and other shade trees.

Treatment: cut and burn badly infested trees. 30 Lunate long sting (Zhalessa lunator). Brownish, wasp-like insect with yellow markings and a slender ovipositor or “ tail” 2 to 4 inches long. Frequents elms and maples infested by the pigeon Tremex and is occa- sionally found with the ovipositor stuck in the wood. The white, legless grubs attach themselves to the borers and suck their life out. This insect should therefore be protected. 31 Cottony maple tree scale insect (Pulvinaria innumerabdilis). Under side of smaller limbs sometimes festooned with this cottony insect, though more frequently it occurs in small masses. Young appear in July. Treatment: spray with kerosene emulsion or whale oil soap solution. Brush or scrape off and destroy the old scales. 32 Sugar maple borer (Plagionotus speciosus). Diseased or loose bark and exposed dead wood indicate the work of this pest. The grubs fre- quently cause serious injury by running transverse burrows just beneath the bark. The stout, black beetles about 1 inch long with bright yellow markings, occur from June to August. Treatment: burn badly infested trees. Dig out the young borers in the fall. Protect trees with carbolic soap wash from June to August. 33 Maple tree pruner (Zlaphidion villosum).

Treatment: collect infested limbs on the ground and burn before spring. 84 Elm leaf beetle (Galerucella luteola). Irregular round holes eaten in young foliage followed by the grubs gnawing the under portions of the leaves, which then dry and turn brown. The yellowish, black striped . beetles, about 1%, inch long, appear in early spring and lay eggs in May. The grubs feed in June, changing to yellow pup& the latter part of the month. A second brood occurs in July and extends into September. Known in this State only on Long Island, in the Hudson River valley and in scattered localities in central New York. Treatment: spray foliage of infested trees with poison, which must be — applied to under surface of the leaf in order to kill the grubs. Kill larvee and pupz on and near trunks of the trees. 85 Elm bark louse (Gossyparia ulmi). Adult females in June appear like clusters of small lichens on the under side of the smaller limbs. of European elms. Young emerge in July. Treatment: spray with kerosene emulsion or whale oil soap solution. Inszurious Insects anD How to ControLt THEM. 79 86 Elm borer (Saperda tridentata). Diseased or dead bark and in inner portions white, flattened legless grubs, which frequently cause considerable injury. Beetles appear from early May till latter part of June. Treatment: cut and burn badly infested trees. Protect valuable trees with carbolic soap wash during May and June. 87 Elm snout beetle (Magdalis barbita). Thick, fleshy, legless grubs working in inner bark of elm. Follows attack by the elm borer and occa- sionally is very abundant. Treatment: burn badly infested trees and keep others vigorous. 88 Fall web worm (Hyphantria cunea). Web tents in July and August inclosing leaves on the tips of branches, the eaten foliage turning brown. Attacks many trees. Treatment: destroy webs and their inhabitants or spray foliage of affected limbs with poison. 39 Bag worm (Thyridopteryxr ephemereformis).

Treatment: collect and destroy bag worms or spray with poison. 40 Leopard moth (Zeuzera pyrina). Whitish, black spotted caterpillars making large burrows in various trees. A bad pest about New York city. Treatment: dig out young borers. Kill others with carbon bisulfid. De- stroy badly infested trees. 41 Bronze birch borer (Agrilus anzius). If injured bark is examined, a slender flat headed grub will be found running burrows in all directions in the inner portions. White and other birches are attacked. Very inju- rious at present in Buffalo. Beetles appear in June. Treatment: cut and burn badly infested trees. Garden Insects. 42 Colorado potato beetle (Doryphora 10-lineata). Stout yellowish beetles with black striped wing covers appear in early spring, feed and deposit yellowish eggs in clusters on under surface of leaves. The reddish, black marked grubs also devour the foliage. Treatment: handpicking; spray vines with poison. 43 Squash vine borer (Melittia satyriniformis). Wilting of one or more runners is caused by a whitish caterpillar boring in the stem near the root. Treatment: slit the softer, infested portion of the vines, remove the borers and cover the wounded part with earth. Protect young plants with netting. 44 Striped cucumber beetle (Diabrotica vittata). Yellow beetles about ¥%, inch long, striped with black, occur in numbers on cucumber and squash vines. Treatment: protect young vines with netting.

Treatment: apply benzine, kerosene or other petroleum oil to crevices in infested beds. Corrosive sublimate may be used in same manner. Fumigation with sulphur is valuable wherever possible. 65 Kissing bug: masked bed bug hunter (Opsicwtus personatus). A brownish or black insect about % inch long. It is attracted by lights, and its young, which conceals itself by a covering of lint, ete., is said to have a partiality for bed bugs. Not usually harmful, though it can inflict & severe bite or “ sting.” Treatment: screens should exclude it most effectually. 66 Buffalo carpet beetle (Anthrenus scrophularie). Larve easily recog- nized by their shaggy appearance, being provided with coarse bristles along the sides and at the posterior extremity of the body. The beetles are about % inch long, black, marked with white and a red line widening into three projections, down the middle of the back. Treatment: use rugs or matting in place of carpets whenever possible. Infested carpets should be taken up and sprayed with benzine and the cracks in floors should be filled with plaster of paris before relaying the carpet. 67 Black carpet beetle (Attagenus piceus). Light brown, cylindric larva with a long “tail” of slender hairs. The adult is a small, oval, black beetle about 1 inch long. This species has a decided taste for feathers. _ Treatment: Same as for the preceding. 68 Little red ant (Monomorium pharaonis). The common yellowish red ant about 3-16 inch long that frequents houses in such numbers at times. Treatment: destroy colony with carbon bisulfid when possible. Attract to sponge filled with sweetened water and kill the collected ants by drop- ping them in hot water. 69 Bacon beetle (Dermestes lardarius).

Some of the more common pollen carriers are honey bees, bumble or hum- ble bees, other bees, wasps, flower of Syrpbus flies and many, others. Bureau or Farmers’ INStTITures. (9 2) wee 80 Lady bugs. Certain species are valuable agents in controlling plant lice, which they and their young feed on. Some forms prey on scale insects. 81 Soldier beetles (Chauliognathus species). The beetles are among the pollen carriers and the grubs prey on the larve of the codling moth. 82 Syrphus flies. The adults are usually seen among flowers but the work of their frequently brightly colored larvz in reducing the number of plant lice is not so well known. These beneficial maggots are nearly coni- cal and may be found among colonies of plant life. 83 Spined soldier bug (Podisus spinosus). Represents a number of species which prey on other insects. This one feeds on various common pests, such as the potato beetle, elm leaf beetle and asparagus beetle grubs. 84 Red tailed Tachina fly (Winthemia 4-pustulata).

Household Insects. By Dr. E. P. Fett, New York State Entomologist. Country houses are the pleasantest on the face of the earth. The person dependent for a living on the profits obtained from the farm may not have a residence quite equal in some respects to the country houses of the wealthy, yet there is no reason why it should not be clean, comfortable and a very enjoyable spot. Such, I am glad to state, is the condition of many farm houses. The presence of almost any insect in the home is troublesome to the housewife and frequently to other members of the family, and when any one species occurs in large numbers, comfort is seriously marred. The farm house is usually distant enough from others so that there is little danger of neighbors supplying us with household pests, and even the greater portion of the house flies probably have origin on our own farms. A serious disadvantdge in city life is the closeness of houses one to another. Almost all kinds of household pests have no difficulty in passing from one to another, while a nearby stable may produce enough flies to supply the entire neighborhood. There is hardly any excuse for such conditions existing in the country, and yet I have been in places where one might almost suppose the house was © built to accommodate the flies. They certainly took possession of everything. Mosquitoes —A large proportion of farm houses are more or less troubled with these tiny pests. We all know that they can be excluded by the use of screens at doors and windows. Is it not practicable sometimes to go behind this and prevent their production? It is well known that mosquitoes breed in pools and some may have seen the black or dark colored, boat-shaped egg masses floating on the water. In about sixteen hours the House Fly and Carpet Beetles.

Next they change to the curious pupa and about two days later the perfect insect emerges. It requires but 10 to 15 days for this insect to complete its life cycle, and the short time necessary for this explains the production of enormous swarms of these winged pests as the season advances, specially when it is remembered that each female may produce from 200 to 400 eggs. Mosquitoes breed, as most of us know, in compara- tively still water, and in many places areas of this kind are some- ’ what limited or else can be reduced materially without much trouble. In many cases the supply of mosquitoes may come from a water barrel just outside the door or from near by pools. If not practicable to do away with these by drainage, it is still pos- sible to prevent to a large extent the production of the insects. The experiments conducted by Dr. L. O. Howard, chief of the Division of Entomology of the United States Department of Agri- culture, have shown that kerosene applied at the rate of one ounce to every 15 square feet of surface and renewed monthly is a most efficient preventive of the breeding of mosquitoes, and one that is practicable when the area of still water is somewhat limited, as is the case in many localities. Kerosene can be ap- plied to tanks or cisterns containing*drinking water without un- pleasant results, provided the water is drawn through a pipe from below the surface. This method is at least worthy a trial in many places. Kerosene applied in like manner to pools frequented by gad or horse flies has resulted in the destruction of many of these annoying pests, and a trial of it is recommended. House Fly.—This is one of our commonest pests (plate 5, figure 1) and its presence in large numbers in the home has too often been taken as a matter of course and no attempt made to mitigate the trouble. We all know that the flies can be excluded from a house to a great extent by the use of screens, but if the creatures can be prevented largely from multiplying, the evil is stopped at its source. It has been found that our common house fly breeds in large numbers in horse manure and also to some extent 88 Bureau or Farmers’ INSTITUTES. in dooryard filth, but the former substance appears to be preferred by this pest. One fly can deposit about 120 eggs which hatch in approximately eight hours. The maggots grow rapidly and in about ten days transform to adult flies. The short life cycle and prolificacy of this insect account most fully for its enormous num- bers in hot weather. In many places it would appear that comparatively little effort would prevent the breeding of the flies to a considerable extent. Either the manure could be spread on the fields daily, as recom- mended by advanced agriculturists, or a dark shed or cellar could — be provided for its reception. The first method would result in such rapid drying of the manure that the flies could not mature. It is not usually very much trouble to inclose a shed or cellar so it will be too dark for the flies to enter, and this plan would therefore result in reducing the numbers of the pests very greatly. With the manure properly cared for and out of reach of flies, and a little cleaning up of other places offering favorable conditions for multiplication of these insects, the fly nuisance would be abated to a very great extent. Fleas.—It occasionally happens that a shed or room in a house becomes infested with these pests. They most likely owe their introduction to the pet dog or cat. The eggs of this insect are deposited among the hairs ‘of its host, but not fastened, so they soon drop to the ground and naturally are most abundant about the sleeping place of the animal. The young emerge from the eggs in about one day, and live in dust and refuse occurring on the floor or in crevices. They require seven to fourteen days to complete their growth, then spin a slight cocoon, and about five days later the jumping adults come forth. The young do not develop successfully in places where they are | frequently disturbed, and the necessary lack of sweeping when a house is closed for the summer is probably the cause of the rather frequent reports of such dwellings being overrun with these pests when the family returns. On general principles it may be assumed that the presence of this pest in numbers in- dicates some favorable, undisturbed breeding place in the im- Hovsenoip INSECTS. 89 mediate vicinity. Frequent brushing and cleaning, supplemented in some instances by the use of fresh pyrethrum powder, benzine, kerosene emulsion or other contact insecticide, will soon stop the breeding of these pests, but may not kill the adults as they are quite resistant to such substances. Where practicable, the adult fleas may be reached by fumigation with sulphur or hydrocyanic acid gas. The latter is very dangerous and the greatest care should be exercised when it is employed. Carpet Beetles and Clothes Moths——There are two species of car- pet beetles commonly found in houses, the Buffalo carpet beetle, Anthrenus scrophularie, and the black carpet beetle, Attagenus piceus. The hairy, shaggy larva (plate 5, figure 2) of the former species is pretty well known to the housewife. The parent in- sect is a small oval beetle about one-eighth of an inch long and prettily marked with red and white on a black background, as represented at figure 3, plate 5. The larva of the black carpet beetle is easily recognized by its slender form and tail of long hairs, plate 5, figure 4. The parent insect is similar in shape to the preceding species, but is a dark brown or black, plate 5, figure 5. The artist has also represented a two-spotted lady beetle (plate 5, figure 6), an insect which is frequently taken for a carpet beetle. This pretty lady beetle and others of its kind are bene- ficial and should be protected. If they can be recognized in no other way, remember that the under side of the lady beetle is nearly flat, while both carpet beetles are very convex and hence will readily rock when placed right side up on a level object, un- less their legs are extended. Before passing to a consideration of remedies, the clothes moths will be briefly noticed. There are several species attacking clothes. Their work is familiar to almost everybody and in a badly infested house it is by no means uncommon to see the deli- cate moths flying about the rooms. The larve, as is well known, show a marked preference for woolen and fur goods. The young of all these insects do not like light, air and dis- turbance. Hence one of the best protective measures, particu- larly for garments, is brushing and airing from time to time, 90 Bureau or Farmers’ Insrirvures. specially in the summer months. It is usually more satisfactory to take up badly infested carpets, beat and air them thoroughly | and, in cases of a bad infestation, spray them with benzine. The room should be thoroughly cleaned and if there are cracks in the floor, it is advisable to fill them with plaster of paris. As a fur- ther preventive, the carpet may be laid on tarred paper or else replaced with rugs. Clothes or other articles put away for the summer can be protected in the following manner: Brush well so as to be sure no eggs or larvie adhere and then lay away in large pasteboard boxes, such as may be procured at a dry goods store, put in some napthaline balls, camphor or similar substance and then seal the cover with a strip of gummed paper. The boxes cost little and if the work is thoroughly done there is no danger of injury by these pests. This method is one recommended by Dr. Howard. He has also found that these insects are not active at a temperature lower than 42° F, and hence storage of valuable furs, etc., at a lower temperature than this may be considered a safe and practical method of preserving them from insect injury. House Ants.——Several species annoy the housekeeper very much at times. The worst of them all, where it occurs, is the little red ant, Monomorium pharaonis, an insect so small that it can hardly be excluded from any vessel. It is represented much enlarged at figure 4, plate 6. As is well known, ants live in nests in soil and not infrequently they establish themselves in underpinning or walls of houses. Whenever possible, seek out the nest and de- stroy the occupants by a liberal use of boiling water, kerosene emulsion, or strong soapsuds. More effective than these sub- stances is carbon bisulfid, which may be used in the following manner: With a broomstick or bar make some holes in the nest several inches from each other and a few inches deep, pour in each about a teaspoonful of carbon bisulfid, cover the nest with a wet blanket and after a few minutes explode the fumes collected underneath with a match on the end of a short stick. Unfor- tunately, it is not often possible to get at the insects in their nests and then we must resort to the laborious trapping with a sponge moistened with sweetened water and dropping the collected pests 3 we C.S5.B arks,del Jas.B.Lron State Printer Bede se SO Sen Ola] tae aote. is. Se oe Hovsrenoip Insects. 91 into boiling water. Lard or fat may be used as a bait and then burned after it has become well covered with the insects. A syrup made by dissolving borax and sugar in boiling water is said to destroy ants in large numbers. This should be preceded when practicable by the removal of other attracting substances. The above measures would prove of value in case of infestation by other species of ants. Cockroaches.—There are two species commonly found in houses, particularly in cities, the smaller, light brown croton bug, rep- resented at figure 6, plate 6, and the larger brown or black cock- roach. The egg capsule of the former is shown at figure 5 of plate 6. Both species prefer the vicinity of water pipes, sinks, etc., and if abundant anywhere in a house are to be found some- where about the kitchen. They subsist on almost any article of food, but it is not so much what they devour as their disgusting odor, etc., that render them objects of abhorrence to the house- wife. The croton bug is more wary than the other species, which latter can be enticed to vessels of stale beer and if sticks be ar- ranged so the creatures can easily get over the perpendicular sides of the vessel and be obliged to drop a little distance in order to get at the liquid, many can be trapped in that manner. Sugar and paris green well mixed and placed about their haunts will soon diminish their numbers greatly, but paris green is a danger- ous poison and can not be used with safety where there are chil- dren. Hooper’s fatal food is said to be nonpoisonous and it has proved itself thoroughly effective in a number of places. Prof. J. G. O. Tepper, Adelaide, South Australia, recommends a mixture of one part of plaster of paris and three parts of flour, with water near by. The roaches are said to eat the mixture, drink the water and die in a short time. The insects are said to disappear in a few weeks. This is not expensive and is certainly worthy a trial. Bedbug.—It is almost impossible to prevent one of these creat- ures from occasionally making its way into the home, particu- larly is this true where many guests are entertained or members of the family travel to a considerable extent. Once in a while a 92 Bureau or Farmers’ Instrirures. family is so unfortunate as to move unwittingly into a house in- fested with this pest. The insect, represented much enlarged at figure 1, plate 6, has probably a slight acquaintance with most of us. The white, oval eggs are laid in batches of from six to fifty in cracks and crevices, as stated by Dr. Howard. They require from seven to ten days to hatch and the life cycle is completed in about eleven weeks. The use of iron or brass bedsteads is to be recommended be- cause they afford so little shelter to the pests. Where large wooden bedsteads are used, the crevices should be liberally treated with benzine, kerosene or corrosive sublimate solution. Hot water, where it can be employed without injury, will kill eges and bugs. This treatment must be supplemented by daily inspections and the destruction of all specimens found. Fumiga- tion with sulphur is reported by some as effective, but others state that it has no value. Treatment with hydrocyanic acid gas would probably be very effective, but it must be used with great care, and there is danger of killing mice and rats in the walls or under the floors and the resulting annoyance. Though red ants are household pests, they are said to wage warfare on bedbugs. The cockroach is also credited with the same useful habit, but un- fortunately neither of these species can be considered desirable acquisitions from the housekeeper’s standpoint. Larder Beetle—The larva and the adult are represented on plate 6, figures 2, 8. This insect occurs in museums and attacks many animal products like hams, bacon, other meats, horn, hoofs, skins, beeswax, ete About six weeks are required to complete the life cycle under favorable conditions ‘The contents of infested rooms should be cleared out and the room fumigated with carbon bisulfied or hydrocyanic acid gas. Infested portions of meats should be cut away and the surface of the remainder washed with a diluted solution of carbolic acid. The parent insect can be ex- cluded from a store-room by the use of screens. Cheese Skipper; Ham Skipper.—The insect is well-known to many in the larval or skipper form though few may be acquainted with the parent fly. This insect is usually found in the best >>, Fic. 5—Lepisma Domestica (After Marlatt: U. S. Dep’t Agriculture Division Entomology, Bulletin 4). Hovusrnoip Insects. 93 cheeses and it is considered a good judge of this dairy product. The parent fly is smaller than the common house fly and like it pre- fers daylight. As the skippers do not cause putrefactive changes, only the portions actually infested need be cut out and destroyed. The flies may be kept away by darkening the room and also by the use of fine screening, a 24-to-the-inch mesh is said to be fine enough. Scrupulous cleanliness and daily examinations in cheese factories will prevent the fly from doing much damage. The in- sect also attacks hams and has been recorded as breeding in bacon. Fruit Flies—The housewife is troubled sometimes by small maggots in preserves. They are also found in decaying and fer- menting fruits. Apple pomace produces them in swarms. Cider, vinegar and allied substances are also agreeable to the insect. The smal] flies deposit eggs which soon produce maggots. Not infre- quently the eggs are placed on the side of a preserve jar and the little creatures work their way through an almost imperceptible crevice into the jar. Preventive measures are found in more per- fect sealing of preserves and keeping them and other attractive substances in the dark, if the flies are at all troublesome. Well fitting, fine screens will exclude the insects from a house. ° Bristle Tail; Fish Moth.—Another insect in the so-called slide, silver fish, bristle tail, fish moth, a small form frequently occur- ring among undisturbed papers, starched goods, etc. This insect, Thermobia funorwn, is shown much enlarged at figure 5, and an interesting example of its work is represented at figure 6. Damp- ness is favorable to its existence. It succumbs readily to fresh pyrethrum powder and ordinarily does not cause much damage, unless articles it likes are left undisturbed for years. (The assistant to the state entomologist, Mr. Charles S. Banks, attended a number of farmers’ institutes and presented substan- tially the same matter as that given in the two preceding papers on insects.) 94 BurREAvU OF Farmprs’ INSTITUTEs.

Tile Drainage.*. By H. BH. Nicotat of Big Bend, Wis. To lay down a specific rule of tiling would be an impossibility for any one, as different lands and conditions would vary the cost of drainage both as to the number of drains required, the amount of labor expended in digging, and also the size of the tiles used. Different Treatment for Different Lands, I have one piece of border land containing fifteen acres, in which the drains are from four to five rods apart, and the drain- age is perfect, while in another piece of only half the size, the drains were put four rods apart and proved to be insufficient to drain the land thoroughly. The former piece is a black sand loam, underlaid with sand and clay, while the latter was a boggy marsh, full of small springs. The top soil was muck, underlaid with clay and gravel. The drains had to be doubled wherever the ground was springy, making them only two rods apart, and the depth of the tiles is about four feet. The cost of this piece was about $30 per acre, while the former was only $10 per acre. Both pieces have been in cultivation ever since they were drained, about ten years ago, and have produced wonderful crops. The average cost per acre of tiling a wet marsh is about $20. The most profit in tile draining is derived in fields that have small basins in them on the elevated parts of the fields, which fill with water during the spring and keep the lower levels of the fields wet and cold until the water evaporates in the basins. One drain with a few laterals in the basin will usually be enough *A paper read before a farmers’ institute in Wisconsin and the discus- sion following. \ Tite Drarnace. 97 in fields of this kind, and the cost will be very small when com- pared with the benefits derived from them. The benefits to be derived from the drainage depend largely on the location, the value of the land, and what crop the land is used for. As no two fields present the same condition, except level marshes, one must rely upon his own judgment, according to the condition and location of the land. How to Tile Drain. ’ First ascertain how much fall there is in the land to be tiled, from the upper end to the outlet. If there is a gradual fall from source to outlet, no survey is necessary, but if the land is nearly level, or if there are any depressions or basins, so that it is hard to determine the amount of fall, obtain the services of a compet- ent engineer to determine the fall from the upper end of the out- let. The fall should be divided up by setting stakes every hun- dred feet and drawing a level line from these stakes. The stakes should be driven close to one side of where the ditch is to be dug. The fall can then be divided by measuring from the line to the bottom of the ditch. From one-fourth to one-half inch of fall to the rod is enough, and in large tiles less fall will do. Digging the Ditch. Commence at the outlet to dig the ditch. If the banks of the ditch have a tendency to cave, the tiles should be put in as fast as the ditch is dug; but if the banks stand firm, it is better to com- mence laying the tiles at the upper end, after the whole ditch is completed. The lower part of the ditch should be dug with a tile spade, the bottom cleaned out with a tile scoop, and the tiles laid with a tile hook. The tiles should be covered with loose soil to the depth of twelve inches. This can be done by breaking down the top of the bank on both sides of the ditch, after which the filling of the ditch can be done with the horses and plow, care being taken not to let the horses get into the ditch and disturb the tiles. 4 98 Bureau or Farmers’ INSTITUTES. Cost of Tiling. 1 will give you a description of a piece of land which I tiled eleven years ago, and also the expense of tiling it at that time. The piece in question consisted of about an acre, covered with water the greater part of the time. Surrounding this water were about four acres of land grown to willows and rushes, also under water during wet seasons. Surrounding this last strip are about four acres of what is usually known as border land (too wet to plow and not wet enough to be called marsh), making about nine acres in all. It was worth, for grazing purposes, at the outside figures, not more than $40 per acre. The expense for draining it was as follows: 2,960. 24-inch tiles.at $10 per, M .)).% te. ssc ee $29 60 1,136.3-inch tiles, at.$12.50 per M.)..2: -c.hcines SOE 14 20 432 4-inch tiles, at $16 per: M...0:).4.0o. «1. eee aoe 6 91 512 6-inch tiles; at:$25 per, M.y' «2. 0%66) ae eee 12 80 EDO Ails isis. xs:a chastity sa cela ied nS a gee da $63 51 10:per, cent: discount for, cash«:. ...0.25% totter 6 35 Leaving total amount paid for tiles...........-..008 $57 16 315 rods of ditch, at SOc) pends: scicicccn/:
