An agricultural colony in Palestine has just applied to the U. S. forest service for help in planting trees to bind the drift- ing sands of the Mediterranean. The colony is near Jaffa, or Yafa, the ancient Joppa of the Bible, and there is being developed in connection with it a seaside resort, with hotel, villas, bath houses, and gardens. The experts of the service point out that the reclamation of sand dunes is not a serious problem in the eastern United States' because the prevailing winds are from the land and the sand is blown into the sea. On the west coast the situation is more serious. The most notable example of reclaimed sand areas there is furnished by Golden Gate Park, San Francisco, where grasses, acacias, and, later, trees and shrubs have converted sand wastes into pleasure grounds of great beauty. The attention of the Palestine colony is called to the wonder- ful reclamation of the Landes, France, where a wealth-produc- ing forest of maritime pine, the source of the French turpentine, has been grown to take the place of shifting dunes The Ameri- can foresters also give the address of the French seedsman who furnished this government with the maritime pine seed which has been used in planting experiments on the Florida national forest, near the Gulf coast. Hampton Institute's work for negroes will probably afford some ideas of value for consideration by the promoters of voca- tional instruction in Hawaii. Anything Hawaii takes up in the way of new agricultural in- dustries is sure to be noticed abroad. Progressive methods appear to be taken for granted as appurtenant to these islands. The best way to live up to this reputation is perseverance in com- bating obstacles of pests and of other things, and by looking out for all good ideas put in practice in other countries of simi- lar conditions. Many things have been fitfully taken up in Ha- waii and abandoned almost at the first blush of misfortune in results. . 212 There is nothing much more in demand today than new mate- rial for paper-making. No doubt there are many plants of tropical and sub-tropical feasibility of cultivation which might be utilized for the purpose in question. Several have been men- tioned in articles appearing from time to time in the Forester. One is noticed in this number. An article descriptive of another is reserved for a later opportunity. With the fuel problem once an obstacle to manufacturing in Hawaii to some extent solved by cheap electric power and mineral oil, the conversion of raw mate- rial into pulp or even finished paper here should not be regarded as a wild proposition. What is most immediately important in the matter is finding suitable raw materials. Hawaii itself is a consumer of considerable quantities of many kinds of paper, while the waste of different of its agricultural products is un- doubtedly suitable for paper-making stock. From the goodly amount of notice Hawaii received in the metropolitan press on the occasion of its slender exhibit at the international rubber exhibition in New York last year, it may fairly be premised that with a worthy exhibit of all of its com- mercial products in London next summer, on the occasion of both the rubber and the tropical products exhibitions to be held there conjointly, everything that these islands are now producing would be introduced to the markets of the world very effectively. No amount of literary advertising will rival such an opportunity of showing the wares themselves to people ready to buy on evi- dence of merit. In addition to the presentation of our products to the attention of European purchasers, the exhibitions in ques- tion will afford one of the grandest opportunities possible for setting forth the attractions of Hawaii to tourists and investors both. All that is needed is taking proper advantage of the big chance. An article in this number, reproducing the suggestions of the University of Nebraska experiment station on the care of milk and cream in the home, should be as valuable in Hawaii as in the northern locality for which it was prepared. Homesteaders in this Territory will find some edifying mate- rial in an article from Australia reprinted elsewhere on the ad- vantages of good cultivation. A request for the Forester regularly has been received from a South African institution, together with a list of names for mailing sample copies to leading agriculturists in that country. The reque_st will be cheerfully complied with. 213 This number contains No. 2 of Messrs. MacCaughey and Emerson's paper on the kalo (taro) in Hawaii. • Reports of the various divisions of the Board of Agriculture and Forestry for July have not been received in time for publica- tion in this number. Cotton growing has been abandoned by the Kunia Develop- ment Company on this island, owing to the ravages of the boll- worm, and the company has given a lease for nine years and nine months of fifty acres of its land to two Japanese, who, it is understood, are raising pineapples on the holding. At last accounts the fungus blight on pineapples on the island of Kauai had become very bad again, after it had appeared to have been overcome, the young plants now being infected. Thus far the blight has not appeared on any other island, and Kauai is being quarantined against it. CONTACT BETWEEN PLANTER AND SPECIALIST. (Agricultural News, West Indies.) Nobody at the present day can fail to appreciate the enormous gulf that divides the practical man or capitalist from the special- ist in science. The separation of the two positions is very patent in modern agriculture, and can be vividly realized by contrasting the mental outlook of, say, the manager of a large sugar estate, and that of the entomologist whose faculties are concentrated on the wing markings of half a dozen species of insects. It is obvious that a proper relationship, or rather a proper communi- cation or contact between the two is of the very greatest impor- tance, and it is the object of this article to delineate the position of the specialist, and to point out the methods that are, or should be adopted, in order that his activities may be utilized to the best advantage. In most of the progressive agricultural communities in the tropics will be found to exist departments (boards, or else en- tirely non-official agricultural organizations, which employ the services of scientific specialists — agricultural chemists, mycolog- ists, entomologists and the like. Strictly speaking — the matter will be enlarged upon later — these so-called specialists are not pure specialists, for in many cases they possess a good general knowledge of agriculture ; yet in spite of this, their work is suf- ficiently restricted to narrow lines of investigation to render their mentalities quite different to those of practical planters. In order to contrast clearly the twcr types, it will be convenient to adopt a figurative illustration. The ability of the specialist may be con- 214 sidered as being represented by a long, narrow, vertical rectangle — his knowledge is deep rather than broad. That of the practical agriculturist can be symbolized in the shape of a square — his knowledge is of a normal nature and quite unspecialized. Clearly these two figures may be equal in area, thereby indicating a com- mon value as regards potential ability, but the essential feature of the conception is that the two figures are so dissimilar in shape that they cannot be made to fit when placed side by side. Occa- sionally, as already hinted, where the specialist has received a general training, and also in a case where the practical agricul- turist has received a special training, the resulting figures have more in common, and may fit fairly well. This ideal condition is seldom found, however, and at present it is generally neces- sary in tropical communities to have an organization at the back of the specialists, of which the main function is to connect up the two dissimilar types just described. It is evident that the knowledge of the specialist is a source which must be tapped. In spite of departments and other or- ganizations, there is a strong' tendency in the tropics, today, for men who were originally specialists to have so acquainted them- selves with the point of view and the requirements of the practi- cal planter that they have become practitioners in the branch of science in which they are interested, and this is frequently fol- lowed by their becoming established in purely administrative posi- tions where they direct the work, and disseminate the results of younger specialists who follow in their wake. The necessity for feeders of knowledge is greater than the necessity for producers of knowledge. This peculiar and most important trend is not altogether desirable, for it leads to the loss of research men just as they are in possession of valuable experience and in a position to tackle local problems deftly and with assurance. In fact, today we find the pure specialist more or less confined to the great centres of learning in temperate countries. There is need for more of these men in the tropics; but, until tropical public opinion better appreciates the value of abstract research by learn- ing how to tap it, there is little prospect of such a change being brought about. In medicine, to strike a parallel contrast, the value of the specialist is clearly understood. The significance of a serious affection of the eye or of the throat for instance, is at once appreciated, and information is obtained by intelligent peo- ple at the right time and from the right authority. On the other hand, of course, an occasional ailment of these organs may be treated without the aid of skilled assistance. Judgment is exer- cised. In agriculture, a similar attitude is very uncommon. In agriculture the tendency is in the direction of laissez faire : unless the specialist rises from his microscope and searches for some- thing to treat, results will be wasted. His mind, however, by in- terruption, is taken off his work, and the results have to suffer in any case. 215 The solution to these difficulties lies mainly in the fact that education and research should go hand in hand under proper con- ditions. At present there are too many isolated attempts at re- search in the tropics and not enough in the direction of broad education. The research man should be allowed to teach the young generation he will later advise. Agricultural education has from time to time been subjected to considerable ridicule by practical agriculturists, even by those who have received one. That is because it has not been correctly administered. Education in agricultural science should have for its main object the teaching of where, when and why to apply for advice, and not aim merely to instil isolated facts and opera- tions or to train specialists. The student who intends to culti- vate land should not, for instance, be taught how to analyze a soil, but rather under what conditions a soil should be analyzed and the usefulness of the results. Consequent on such a widening of the practical man's square — to speak again figuratively — his contact with the specialist will be increased without interfering either with his own particular depth and kind of information or with that of the specialist. It is true that specialization might progress, under such conditions, more rapidly than the practical man could keep up with, in which case the class of scientific practitioner already referred to, would quickly evolve; but it would be from a different cause, a more desirable cause than that which necessitates the combination of agriculturist and scientific specialist in one, at the present day. With the extended appreciation of scientific results by the agri- culturist, the necessity for a large number of agricultural depart- ments would tend to diminish. The State would be relieved of responsibility. Taxation would be less. The planter does him- self what he paid others to do. Men of administrative ability would be required in the various communities to direct local cooperative movements it is true, but they would be entirely un- official. A priori, one other thing would be necessary. Those who intended to undertake the cultivation of the land, who did so with the fixed intention of discreetly utilizing the knowledge of the specialist, would need to be catered for by the establishment of an inexpensive and easily accessible tropical agricultural uni- versity. PROBLEMS IN PROPAGATION BY CUTTINGS. Professor Bayley Balfour, F. R. S., delivered as the eighth "Masters Lecture/' an extremely interesting and practical dis- sertation on the subject of propagation by cuttings. The lecture is published in the lournal of the Royal Horticultural Society, Vol. XXXVIII, Part 3. Professor Balfour commenced by raising the question as to 216 the truth of the commonly made statement that many plants can- not be propagated by cuttings. In the course of the lecture it is made evident that in the light of modern investigation this statement is unjustified. Two remarkable cases are cited early by way of illustration: one being the case of a species of Gyp- sophila, which was formerly believed to be unresponsive to vege- tative propagation, but which had been shown by the author to be easily reproduced by internodal cuttings. The second case con- cerned a plant of great importance in the tropics — the bamboo — which until recently had been considered only sexually repro- ducible. Professor Balfour, however, has shown the bamboo to be readily increased by cuttings. Proceeding next to general considerations of the most interest- ing nature concerning plants as individual organisms, it is pointed out that a plant, unlike one of the higher animals is not, strictly speaking, one individual. It is a colonial organization. "A plant is composed of a sheet of protoplasm (living substance) stretched over a skeleton." A limb of a plant can be removed and another will grow to replace it; if the limb of an animal be removed, only mutilation can result. A plant is therefore potentially im- mortal. Two common instances of vegetative reproduction in nature were next cited — those of the iris and the strawberry. The for- mer plant creeps along under the soil forming new additions to its body: in fact it is an accident if the plant does not continue to live for ever. In the case of the latter example, the plant extends itself by runners — by the formation of roots near the terminal bud at the end of the prostrate offshoot. Consideration of these two cases shows that the necessary con- ditions for reproduction are (a) that the young buds which give rise to the new shoot must receive ample food-supply from the parent plant until it has rooted itself; (b) that there be water to stimulate root development. These two facts are of primary importance. After referring to the advantages that accrue to gardeners from the presence of the bulblets, corms and the like amongst monocotyledonous plants, the author proceeded to the important subject of callus formation in relation to vegetative propagation. The growth of callus consists in the formation of a mass of living cells under the stimulus of wounding. In an ordinary dicotyle- donous stem or root it may take origin in the pith, in the medul- lary rays, in the cortex, or in the active wood cambium, and it forms tabulated projecting masses at the point where it occurs. Callus more rarely forms in monocotyledonous plants — these are content to heal wounds by a cork covering only; when it does appear, however, it arises from the cortex of the stem. Callus formation is a mark of the colonial organization of the* plant . already referred to. It is associated with the formation of adven- titious roots. ^217 In continuation, the lecturer proceeded to contrast the readi- ness with which can be propagated cuttings from soft-wooded and hard-wooded plants. The difficulty met with in the case of hard-wooded plants is explained by the fact that the absorption of water is less easily effected than in the case of soft cuttings. For other reasons, which are later referred to, resinous plants, and those rich in latex may also be difficult subjects for propaga- tion by cuttings. After pointing out the nature of the development of a dicotyle- donous cutting, the question as to whether it is advisable to re- move the leaves at the base of a cutting is referred to. It is pointed out that the practice of leaving them has these advan- tages: (a) the cutting is saved the healing of the wound caused by their removal; (b) the lower leaves sunk in the soil may root like the stem and aid, thereby, water absorption; (c) the lower leaves will aid in the manufacture of food for the cuttings. Another point considered was the fact that some plants propagate far more readily if the cutting be made through an internode than through a node, and vice versa. As an illustration, Clematis cannot be propagated if nodal cuttings are used, whereas inter- nodal cuttings may be "struck" within a fortnight. It is indicated that an investigation of the causes of such differences in cuttings- is one of the problems of propagation which yet remains to be solved. Alluding again to callus formation, the interesting and ex- tremely important feature was noted that, however difficult it may be for a cutting to strike, yet once callus is produced, root development can always be stimulated by paring this callus. After referring to the importance of the size of cuttings illus- trated by the fact that small cuttings of hard wood plants ger- minate quicker than large ones, the lecturer dwelt upon the sig- nificance of resin in relation to propagation. When, for instance, cuttings are taken from coniferous trees, the shoots instead of producing callus, generally excrete resin. This flows out copious- ly over the surface, covering it effectively with a hard skin, there- by constituting a hindrance to the exit of young rootlets. It is necessary not only to remove this resin but to check its exudation. This can be done by plunging the cut end of the cutting in nearly boiling water. The cut resin canals are thus sealed and doubtless at the same time the heat stimulus promotes formation of callus. Dicotyledonous plants with resinous and milky juice are in like case with coniferous, and require to be treated after 1jie same fashion. The actual state of a shoot to be used for a cutting was another point taken for consideration. A vigorously growing shoot re- moved from a plant and at once placed in the nidus for propaga- tion may fail to "strike. ;, Its vigor is probably too great. The 218 soundness of the practice of allowing some cuttings to dry slight- ly before planting in soil is clearly supported by this interesting feature of development. — Agricultural Neivs. RECENT WORK ON THE PARASITES BELONGING TO THE GENUS GLOMERELLA. Of recent years problems in mycology have been regarded from a much wider point of view than was formerly the case. Particularly is this so in respect to that branch of the subject known as parasitology. As an illustration of this new phase, the work of Shaw in India on Rhizoctonia may be cited, and as a still later example, may be mentioned the recent work on the parasites of the genus Glomerella, conducted by C. L. Shear and Anna K. Wood of the United States Department of Agriculture. A complete account of this latter investigation has just been published as Bulletin No. 252 of the Bureau of Plant Industry, and from this interesting and important paper most of the in- formation in the following article has been abstracted. The name Glomerella is applied to the ascogenous forms of Gloeosporium or Colletotrichum — form-genera of the fungi im- perfecti, the parasitic nature of which is well known in the West Indies. The objects of the work under review were to study the production of the ascogenous stages, and to determine the habits and identity of the numerous forms of Gloeosporium and Colletotrichum found upon the same hosts, and upon different hosts. The method of study adopted was to observe the behavior of the different forms in the moist chamber and in pure culture, and to carry out a large number of cross inoculation tests to find out whether a so-called species of Glomerella found on one host, say on the cotton plant, could infect another host, say the avo- cado, on which a supposed different species of Glomerella was regarded as being individually parasitic. Apart from its general interest, the economic value of such an investigation is readily apparent. With particular reference to the life history of Glomerella it is important to understand that until recently, the two principal spore forms, conidia and ascospores, have been described and treated as distinct organisms. As is already pointed out, the conidial forms are well known under the name of Gloeosporium or Colletotrichum. The essential feature of the work under re- view isuthat ascospores, conidia and chlamydospores or appres- soria (resting-spores) are shown to be normal stages in the life- history of the genus. These facts greatly simplify the generic classification of the forms. In regard to the thirty-six hosts — of which the names of some are given later — that have hitherto been considered as being 219 attacked by thirty-six diffeient species of Glomerella, it has been found that neither morphological nor physiological differences can be observed v/hich are sufficiently constant to be regarded as specific characters. All the different forms have been referred by the authors to three species of Glomerella: G. cingulata which occurs on thirty- four of the hosts, G. gossypii on one (namely, cotton), and G. lindcmuthianum, on one. G. cingulata is exceedingly variable in all its characters. The cause of this variability is not yet clear. The essential point about this fungus is that it can often be found to grow from apparently healthy tissue, which has been washed in corrosive sublimate. The explanation is that the chlamydospores send a germ tube down through the epidermis of the host plant, which lies quiescent until the plant becomes weakened from some physiological cause, when the fungus begins to develop as a vigorous parasite. It is stated by the authors: " Inoculation experiments with fruits have shown that most of the forms from different hosts will produce the characteristic Glomerella rot on fruits of other hosts. It is also shown that there is a "great variability in the virility of different races or strains of the fungus from the same host. In one experiment races from the lemon, grape and fig produced more serious cases of bitter-rot of apple than a race of the fungus derived from apples. These facts are of great im- portance in connection with the selection and production of dis- ease-resistant varieties of plants." It may be added, further, that this is of immense importance in regard to mycological legislation, in view of the fact that the disease can apparently spread as easily from temperate countries to the tropics, as within the tropics itself. It must also be remem- bered that G. cingulata can also be carried by any one of thirty- four different species of agricultural plants, including such diverse forms as palms, oranges, apples, gooseberries, cacao and arrowroot. Of great economic significance is the fact that one species of Glomerella is confined to cotton. This species, it may be added, occurs in the West Indies and causes the well-known disease, anthracnose. The production or non-production of the perithecial stage of Glomerella appears to be a fairly well-marked hereditary race character. There is no evidence to show that the production of perithecia is controlled by any of the ordinary conditions of nutriment or environment, though accurate investigation along this line would possibly lead to results of great importance. In conclusion, the methods of controlling Glomerella may be briefly summarized as follows : ( 1 ) spraying with Bordeaux mix- ture; (2) selection of fungus- free seed — particularly valuable in the case of cotton; (3) eradication and destruction of dead and diseased parts of infected plants. The selection and breeding of resistant varieties may also be practicable in some cases.— Agricultural News. 220 GOOD ROADS AND THE ELWELL LAW. By Senator James T. Elwell of Minneapolis. The Elwell Road Law was enacted for the purpose of building leading roads throughout the State of Minnesota, and to do it in a large and comprehensive manner, so as to connect city with city, and village with village, and to give to the citizens of each county easy access to their market towns. The general plan embodies the idea of getting into one lump sum for each county of the state, enough money at one time to build the main arteries of travel for each county. By its provisions any county in the state may build $200,000 worth of good, permanent road which will not only aid the farm- ers of such county in getting to their market town, but will also be an example to them of the kind and character of road which can and should be built to connect with these main arteries. GENERAL PROVISIONS ARE SIMPLE. The general provisions of the bill are simple, although the ma- chinery ?.s quite lengthy and explicit, as that feature of the bill is provided for by adopting the main features of Chapter 230 of the 1905 Ditch Law. Under the provisions of the Elwell law, the state pays one-half the cost of the road, the county one-quar- ter, and the benefited property the other quarter, each having ten years in which to make their respective payments. The county is made the financial agent and it issues the bonds or certificates of indebtedness of the county payable in from one to ten years for the entire cost of any and all roads to be built within the county limits, thus providing for the payment of any and all roads to be built under this law. Each road or system of roads to be built will have the advan- tage of having the cash on hand to pay for the improvements as they are made. All roads, after a careful survey and proper advertisement, will be let to the lowest bidder who will give the proper bonds assuring the county and the State Highway Commission that the work will be done satisfactorily, and in accordance with the plans and specifications of the State Highway Commission. It is expected under this plan of procedure to interest large contractors who have the proper machinery and equipment of every kind for grading and building roads, thereby saving the county under our present plan of building roads from 33^ to 50 per cent. The time has passed when the farmer desires to work on the road, as he can make more money by attending to his farm duties, and the man of large experience with proper ma- chinery can do the work for from one-third to one-half of what it will cost the farmer to do the same work. 221 Then, too, the large contractor with his heavy machinery traveling over the road while it is being built, will be able to roll down a new road so that when completed, it will be as compact and as good for travel and heavy hauling as an old road. This has already been demonstrated under the provisions of the Elweil law in Winona county where the first contracts were let for practically $116,000. The contractors have demonstrated that they can haul, with their up-to-date machinery, gravel and road material for from ten cents to thirteen cents per yard per mile, when the hauling from the same pits and under like conditions costs from thirty-five to fifty cents to haul with teams. The large contractor has the advantage of using his heavy 'machinery 2Z]/ 2 hours out of 24 each day without crippling the efficiency of his plant; and where all of the material is handled with steam shovels, and wide-tired wagons with self-dumps, it can readily be seen it is easy to do this work for from one-third to one-half the ordinary cost and yet be able to pay his men who do the work large enough wages to satisfy them and to insure their earnest and faithful cooperation in completing the work. PROCEDURE UNDER THE LAW. In proceeding under this law ; first enlist the cooperation of the County Commission by petition or otherwise and make a prelimi- nary survey which need not be expensive, by a competent en- gineer and file this preliminary estimate of the cost of the im- provement with the County Auditor, and a copy of, the same should be filed with the State Highway Commission. The County Commissioners should then approve the road, ?fterwards, the Highway Commission approving same. The next step would be for the final survey of the road which could be made by the State Engineer or by a competent engineer whose work would meet with the approval of the Highway Com- mission. After a proper hearing before the County Commissioners, and a determination to build the road, viewers are appointed by the County Commissioners to spread the assessment of one-quarter of the cost of the road. These viewers are three in number and must be men who are not in any financial way interested in the construction of said road. The assessment may be spread in the discretion of the viewers any distance which is proper and right and where they think there is benefit. PLAN FOR NORTHERN MINNESOTA. In Northern Minnesota, the general plan is to spread the assess- ment three miles either side of the center of the road, and on a good gravel road, costing $1,500 per mile, the assessment averages 222 one cent an acre per year for each of the following ten years with interest on same. A good gravel road costing $1,000 per mile with assessment spread two miles either side of the center of the road would be the same amount, or, if spread three miles would be less than three- fourths of a cent per acre. No farmer that we have ever seen has objected to the amount to be assessed against his land under the provisions of this law when he knew exactly the amount which would be assessed to him for benefits, as in nearly all cases this kind of a road would s^ve him in hauling his produce to the market several times its cost each year, besides the added pleasure of driving over a good road. EVERYONE INTERESTED IN ROAD. One of the good features in this road law, is that everyone is interested in its cost and construction. The state, because it pays one-half; the county, because it pays one-quarter; the in- dividual benefited and living near the road, because he contributes his share of the last quarter of the cost of the road. With everyone interested, with money in hand to pay for all work when it is completed, a good road should be built at the right cost. WHAT MAY BE DONE UNDER LAW. Finally to sum up what may be done under this law, the State of Minnesota is at the present time able to build $21,000,000 worth of good road, or more than $200,000 worth of good road in each and every county of the state, and if we put into opera- tion this law to its fullest extent, we double the value of every acre of land in the state, provide ourselves with all the main roads necessary, and make Minnesota a leader in good roads. — North Woods. RUBBER-VINE CULTIVATION IN THE BAHAMAS. It is mentioned in the Journal of the Royal Society of Arts for April, 1913, that an extensive cultivation in the Bahamas of the rubber vine Cryptostegia grandiHora is in contemplation. It is understood that approximately 5,000 rubber vines will be planted to the acre. After six months' growth the rubber vine is said to attain a length of 12 to 30 feet. The vines will be cut in about twelve months, when there will be presumably about 2 lbs. of shrub to the plant as a minimum, yielding about 2 per cent, of rubber, or 200 lbs. to the acre. According to the Ameri- can Consul at Nassau, a large number of shoots to be planted in the Bahamas have been ordered from Mexico, and special machinery for extracting the rubber and fibrous by-products by a secret process has been ordered from the United States. X 223 The rubber juice is contained chiefly in the lactiferous ducts of the bark, but to some extent also in the wood of the stem — in fact, the entire plant contains a certain amount of rubber. While the process of extraction is secret, yet in the main, it appears that it is analogous to the production of sugar from the sugar-cane. The fibrous by-products of the rubber vine are considered as possessing an importance possibly greater even than that of the rubber itself. The bark of the vine yields 6% of the weight of the whole stem, and is a pure cellulose fibre, having a silky lustre comparable to Japanese ramie fibre and almost equal to cotton. It is thought that it can be used as a substitute for Egyptian cot- ton, especially in the manufacture of fine underwear and other articles. The pods of the vine besides containing a fair per- centage of juice, have large quantities of silky cotton such as would be suitable for stuffing pillows ; when refined and specially treated, it can be successfully spun with ordinary cotton. The woody substance of the vine, when bleached and worked out, yields a fibre suitable as paper pulp. The vine can be best har- vested after the fruiting period. — Agricultural News. LONDON OFFERS GOOD CHANCES FOR PROMOTION. (TJonolulu Star-Bulletin.) According to the printed matter issued relating to the Fourth International Rubber and Allied Industries Exhibition, and the First International Cotton, Fibers and Other Tropical Agricul- tural Products and Allied Industries Exhibition, to be held con- jointly in London from June 24 to July 9, 1914, both days in- cluded, every opportunity will be given to each country exhibit- ing to obtain individual publicity in special ways. Thus it is stated : "Special rooms will be provided for demonstrations, lectures, addresses or other functions, as well as theaters for moving pic- tures showing the production, packing, shipping and manufactur- ing of the crude products for commercial use. In all cases the films must be supplied by the exhibiting countries. Particular mention is made of the fact that no charge will be made for these concessions. "The exhibition permits of the display of every description of commercial products grown in the soil, also of the allied industries, as well as manufactured products, machinery and appliances. "Many of the British and foreign governments, also associa- tions, companies and firms, have intimated their intention of being represented in the various departments. "All countries exhibiting, whether through the governments of associations, have the privilege of issuing special invitations to the press, to those interested in their respective countries and to 224 any others they may desire to invite, when special addresses may be given on the resources and attractions of the country and that particular day will be known by the name of the country. For instance, 'Ceylon Day/ 'British Malaya Day/ 'Brazil Day/ etc." If Hawaii be represented, there will be "Hawaii Day," of course, when Bonine pictures of Hawaiian industries and scenic attractions should be given. Artist Hitchcock, on being asked by one of the Hawaiian members of the honorary advisory com- mittee, has stated that he would be very pleased to send some of his paintings of Hawaiian scenes to the exhibition. Members of that committee selected from Hawaii are Wilbur A. Anderson, secretary of the Hawaiian Rubber Growers' Association; Dr. E. V. Wilcox, special agent in charge of the Hawaii Agricultural Ex- periment Station; F. T. P. Waterhouse, secretary of the Water- house Co., Ltd. ; Albert Waterhouse, president of the Waterhouse Co., Ltd., and member of the board of commissioners of agri- culture and forestry; W. P. Thomas, pineapple grower and packer ; Jared G. Smith, tobacco grower and formerly special agent in charge of the H. A. E. S. ; William Weinrich, fiber ex- pert, and Daniel Logan, editor Hawaiian Forester and Agricul- turist. Mr. Anderson is also officially listed as one of the patrons of the exhibition, along with the Earl of Derby and many other distinguished persons and associations throughout the world. RUBBER IN HAWAII. In a report by the Acting British Consul at Honolulu on the trade of Hawaii in the year ended June 30, 1912, which will shortly be issued, it is stated that rubber is steadily becoming a more important item of Hawaii's products. On the Island of Maui many trees have been planted, and these are now tapped in large numbers. Steady efforts are being made to improve the methods of preparation in order to increase the marketable value. During 1912, 35,000 were tapped, and altogether some 8,000 lbs. of rubber were expected to be produced, most of which will be exported. For 1913 an output of 20,000 lbs. is anticipated. At- tention has been directed to an indigenous rubber tree ( Euphorbia lorifolia), which grows in several localities, one place in partic- ular on island of Hawaii having 6,000 acres, averaging 75 trees to the acre, whose product is 14 to 17 per cent, of rubber and 60 per cent, of resin (chicle). It is reported that the latex contains 42 per cent, of solid material, and that one man can collect 16 to 30 lbs. of crude product per day. — Financier, April 1. 225 THE KALO IN HAWAII (II). By Vaughan MacCaughey and Joseph S. Emerson. 3. THE FLOWER. The production of flowers and seeds is uncommon in the case of the kalo plant. Like many other tropical plants, it has come to rely upon asexual, rather than sexual, methods of propaga- tion. The plant develops vegetative rather than reproductive tis- sue. Plants that have a similar habit are banana, sugar cane, sweet potato, breadfruit, and hau tree. It is probably desirable, from the standpoint of the economics of the plant body, that flow- ering and seedage be suppressed, in such plants as the kalo. The part of commercial value is the corm, a vegetable part, which would suffer if material were drawn from it to nurture flowers and seeds. * When blossoming does occur in the cultivated kalo, the flowers appear shortly after the hull have been planted, and frequently before the leaves have appeared. In the wild kalo, flowering, if it occurs at all, is deferred until very late in the life of the plant. By hull is meant the large central bud that is cut from the top of the corm, together with the adjacent leaf-petioles, and is used to progagate the plant. This is the common type of hull; others are discussed under Propagation. The flower arises, as do the leaves, from the center of the leaf cluster. It is yellowish or creamish in color, and resembles in shape and structure the calla lily or the Monstera flower. The central club-shaped order, or spadix, is enclosed by the pointed, hoodlike cover or spathe. The spadix bears the many small florets, staminate and pistillate. The extreme tip of the stadix is sterile, and is usually closely confined by the strongly twisted spathe. Fertile seeds rarely develop. The method of pollination is not known. It is interesting to know that the flowers of plants closely related to the kalo are pollinated by snails.* Interesting contrasts will be discovered if one makes careful observations of the flowers of some wind-pollinated plant, such as sugar cane, bamboo, corn, sorghum, grass, coconut palm, and some insect-pollinated flowers, such as those of nasturtium, hi- biscus, hau, lehua, and compare these with the kalo flower. * The only snail occurring in the kalo patches of Hawaii is a large -aquatic snail imported by the Chinese in recent years. 226 CORM OF PI'IALI'I ULAULA. Weight, 915 grams; dimensions, 16.5 cm. long by 11 cm. diam. This is. a type of corm found commonly in the markets. 227 4. THE CORM. It is for its starchy corm or "root" that the kalo is chiefly raised, although other portions of the plant have some value as food. A full-grown corm of average size is as large and as heavy as a large sweet potato. It is covered with a fibrous or scaly bark, especially towards the summit. Just beneath this outer bark is an inner layer, which may be white, rose, greenish, or purplish in color, depending upon the variety. ' The interior of the raw, corm is usually light gray with a slight-bluish tinge, but in some varieties may be yellow, orange, rose, or even purple. For many years the acrid or toxic effect of certain aroids was not understood. Professors Pedler and Warden, of the Depart- ment of Chemistry, Calcutta University, first demonstrated the presence and action of the calcium oxalate crystals. The fol- lowing excerpts from their paper in the Journal of the Asiatic So- ciety of Bengal, Vol. 57, Part II, No. 1, for 1888, prove of interest in this connection. Their experiments were performed upon Co- locasia virosa Kunth, which at that time was called an Arum. After prolonged and varied chemical tests they stated that "The examination of the ash thus failed to afford us any clue to the physiological action of the fresh tubers. "It now occurred to us that possibly the painful effect produced by Arum when in contact with the tongue, etc., might be due to mechanical causes. A microscopic examination of a section of a tuber revealed the presence of very numerous bundles of needle- shaped crystals, and we also found similar crystals in the leaves and stems. These crystals were seen under the microscope to be insoluble in cold acetic acid but easily soluble in cold diluted nitric or hydrochloric acid. * * * There appears to us to be no reason to douBt the fact, that the whole of the physiological symp- toms caused by Arums are due to these needle-shaped crystals of oxalate of lime, and that the symptoms are thus due to purely mechanical causes. Bearing in mind the action of re-agents on calcic oxalate, the reason why mere boiling in water failed to deprive them of their activity is explained by the insolubility of oxalate of lime in water. Again, the action of dilute acetic acid, even at temperatures of 100 degrees C, in slightly lessening the activity of the tubers, is due to the very slight solubility of oxa- late of lime in that acid. And, lastly, the complete loss of all physiological action when the tubers were treated with dilute nitric or hydrochloric acid is evidently due to the ready solubility of calcic oxalate in those mineral acids. And these assump- tions, as we have already indicated, were fully demonstrated by the microscopic examination of sections of the tubers treated with the re-agents we .have mentioned. One point, however, remains to be explained: we observed that, on drying, the tubers lost practically the whole of their physiological activity. Clearly there 228 could have been no loss of oxalate of lime on desiccation, and, as a matter of fact, we found as many crystals on microscopic ex- amination of dried Arums as we had found in the fresh tubers. We explain this apparent anomaly in the following simple man- ner. In the fresh condition of the tubers, the bundles of crystals of oxalate of lime are cone-shaped, more or less, the sharp points covering a wide area, and forming the base, but in the drying of STRUCTURE OF THE KALO CORM. Transverse section through a corm of Pi'iali'i ulaula. The starch-con- taining parenchyma is quite moist, and very firm. The bark is both scaly and fibrous. The laticiferous tissue is conspicuous. the tubers, the needles appear to arrange themselves more or less parallel to one another, and the sharp points thus cover a smaller area. And thus, instead of each crystal acting as a separate source of irritation and penetrating the tissues, the bundles act as a whole." The acrid effect of the crystals, or raphides, is destroyed by drying, boiling, or steaming the corm. 229 Upon the outer bark may be seen the scars of former leaves. From these scars the roots commonly emerge. Small roots may be seen in' the axils of the leaves still present if these leaves are pulled downward so as to expose the corm. The roots them- selves are coarse, rather long and string-like, somewhat brittle, and whitish in color. "They contain little of the milky latex which fills most of the other organs of the plant." — Barrett. The roots bear a few branching rootlets. Kalo is not especially deep-rooted. Young kalo plants sometimes develop from underground root- like runn^fs sent out from the corm. Plants may also develop directly from the corm by budding. These lateral offspring are called hull oka, or hull pu'u, and are described under the head of Propagation. The corm, which because of its subterranean position is com- monly thought of as a root part, is really a modified stem, as is demonstrated by the leaves which it bears. True roots do not bear leaves. Its swollen shape is due to the fact that it is stuffed with starch, which is the food part. Other familiar plants that store up large quantities of starchy or sugary material in their stems are: sago palm, cycads, sugar cane and potatoes. This stored food is protected from the attacks of animals by its secure position within the wet soil, by the outer husk or bark, and by the protective layer of minute, needle-like crystals of calcium oxalate. These occur both in the leaves and in the outer layer of the corm.* Anyone who has inadvertently eaten kalo that has been insufficiently cooked, can attest to the prolonged and sharp pricklmg irritation, as though one's mouth and throat were veri- tably "full of needles." 5. BOTANIC STATUS OF KALO. The botanic liame for kalo is Colocasia antiquorum var. escu- lenta Schott. This means that it is a member of the genus Colo- * The use of root crops as food by primitive peoples is interestingly de- scribed by O. F. Cook as follows : * i The root crops that were domesticated in America stand in distinct contrast with Old World root crops, both in number and in quality. The species cultivated in the Old World were rela- tively few, mostly the seed-propagated garden vegetables of temperate regions, such as radishes, turnips, beets, parsnips, carrots, etc. The tem- perate root crops domesticated in the Old World were mostly capable of being eaten raw, as though they had been used first by people unaccustomed; to use fire for cooking vegetables. The root crops that were domesticated in America are not eaten raw by the natives. Many of them are disagree- ably acrid in the raw state, like the aroids, or even positively poisonous, like the cassava. Very few new types of plants appear to have been domesti- cated as root crops in the Old World Tropics, and none of them have at- tained the prominence of several of the American species. The banana appears to have been cultivated first as a root crop, and some of the varieties are still cultivated for their root-stock in New Caledonia and in East Africa.' ' 230 STRUCTURE OF THE KALO PLANT. Longitudinal median section, through petioles and corm. The marks in the corm are due to the latex, which turns brown when the latex tubes are cut and exposed to the air. Note the triangular mass of embryonic tissue, centrally located amidst the bases of the petioles. From this region the foliage and floral organs are produced. This kalo is Pi'iali'i ulaula. 231 casia (which is the old Greek name for plants of this general type). The specific name antiquorum indicates the antiquity of its culti- vation, for kalo was among the plants first used by mankind for food. There are several varieties of this species, as shown in the botanic syhQpsis given later. The kalo of Oceanica and Hawaii is the particular "variety esculenta, so-called because of its exten- sive use as food. The botanic name for kalo w^as given it by the German botanist Heinrich Wilhelm Schott, who lived during the years 1794*1865, and who made a careful study of the plants of this group. The Hawaiians had a number of poetical appellations descrip- tive of the kalo. Among these is ka i'a iwi ole" which means "the fish without bones." This refers to the importance of kalo in the diet — it held the same high rank among the vegetable foods that fish held among the flesh foods. SOME SUGGESTIONS REGARDING THE CARE OF MlLK AND CREAM IN THE HOME. (Press Bulletin No. 42, the University of Nebraska Agricultural Experiment Station.) By J. H. Frandsen. Sanitary milk is milk produced from healthy cows under condi- tions which prevent all outside contamination. The production of clean and healthful milk is the most important subject with which the dairyman has to deal. Considered from an economic standpoint, we find milk produced under absolutely sanitary con- ditions selling; ipv practically double the ordinary price. Need- less to say, for the production of sanitary milk the dairyman must have healthy cows, a sanitary barn, clean bedding, dust-free air, a clean barnyard, and clean cows. He must have clean and healthy milkers, clean milk vessels, and pure water. He must feed clean, wholesome feeds and must have a sanitary milk-room and abun- dant facilities for cooling the milk%and cream. However, if care- lessly handled in the home the milk or cream ma|kquickly become unfit for food. The fact that such large quantities of good milk have been spoiled in the home by improper treatment after de- livery prompts the writer to emphasize some of the points regard- ing: care of milk and cream in the home. Milk and cream readily absorb odors and collect bacteria and other impurities whenever they are exposed to the air or placed in utensils that are not scrupulously clean. If this fact is gen- erally understood it can easily be seen why it is so objectionable to store uncovered milk in refrigerators or cellars, where it comes in contact with vegetables or other food products possessing 232 strong odors.. Milk is almost a perfect food for human beings. It is also a perfect medium for the development of certain bac- teria which may gain access to it from the dust-laden air, from flies, and from unclean utensils. Some of these bacteria may be the germs of contagious diseases ; others may cause digestive disorders, especially in infants and young children whose diet is largely milk. Experiments have shown us that many germs' which gain access to the milk develop very rapidly while the milk remains warm. By this we mean at a temperature above 50 degrees Fahrenheit. For instance, milk kept at 45 degrees F. may be kept perfectly sweet for twenty-four hours, while if kept at a temperature of 70 degrees F. it may sour in less than six hours. This emphasizes the importance of low temperatures in the preservation of milk and cream. The following brief rules should enable the consumer so to care for the milk as to have an article that is at all times sweet and wholesome : 1. If possible, purchasers should insist on getting milk in a bottle or other originally sealed package. Milk dipped out of a can in the street may gather large numbers of bacteria from the dust and impurities in the air falling into it. 2. Never allow the milk to stand in a warm place for any length of time, but place as soon as possible in a refrigerator, ice box, or other cool, clean place. 3. Keep the milk or cream in the original package until needed for use. 4. Carefully wipe the mouth of the bottle before pouring milk or cream from it. 5. Do not pour back into the bottle any milk which has been exposed to the air. 6. Keep the bottle covered with a cap or an inverted tumbler as long as any milk remains in it. 7. Do not expose uncovered milk in refrigerators containing foods having a strong odor. t 8. Wash milk bottles as soon as empty and do not use milk utensils for any other purpose. 9. Wash milk bottles in pure water and do not wipe with dish towel. It is better to scald them in clean water and set away unwiped to dry. 10. Special precautions should be taken with the baby's milk bottles. They should first be rinsed in lukewarm water, then washed in hot water containing a little soda, and then scalded. In selecting a feeding bottle, choose one with a wide mouth and no corners. Never use rubber tube between the bottle and the nipple. 233 11. In case of contagious diseases in the house, such as typhoid, scarlet fever, or diphtheria, return no milk bottles to the milkman without the permission of the health officer. ADVANTAGES OF GOOD CULTIVATION. Mr. B. G. Brooks, Instructor in Agriculture, has contributed the following article to the Queensland Agricultural Journal of Feb- ruary, 1913: In the successful raising of farm crops the management of the soil is of the greatest importance. It is only necessary to observe the variations in the yield of similar crops on adjoining fields to find that, were up-to-date methods more generally practised in the preparation of the soil, the returns per acre would be mate- rially increased. When a crop fails the cause is, unfortunately, too often set down to adverse climate conditions. Although the weather has undoubtedly a very important bearing upon crop production, yet it is not always responsible for the poor returns. In my travels throughout the various districts of the State, I have ample opportunity of studying the respective methods prac- tised in the raising of crops and the results obtained thereby. It is not an infrequent occurrence to come across a farmer har- vesting a very heavy crop on one side of the fence, while his neighbor on the other, on similar soil, is reaping practically a failure. It is, therefore, necessary to look to some cause other than the weather for this disparity. Perhaps there is some truth in the remark made by the farmer who was harvesting a fine crop while his neighbor was reaping a poor one. When risked the reason for the difference, his reply was, "I cultivated my soil — my neighbor irritates his." The problem relating to soil fertility and crop production has received much attention from agricultural scientists during recent years, and although much has been achieved, there still remains a very large field for investigation. Much prominence has been given, both in Australia and America, to the raising of crops with a minimum amount of rainfall, and it must be admitted that mar- velous results have already been secured by the adoption of the methods advocated. The foundation stone upon which the success of the dry-farming system rests is fallowing — that is, keeping the soil cultivated and only taking- a crop every alternate year. So far, fallowing has received little or no attention in our State. On the other hand, the practice of securing two crops during the year is quite a general one, and this is undoubtedly, to a large extent, responsible for the low average yield obtained from some of our staple crops. I find that one of the most important factors in successful crop production is the early preparation of the land, 234 but, with the system of double cropping just mentioned, this cannot be given effect to. I am not inferring that cultivation is carried out in a slipshod manner, for it may be that every care has been taken in plowing and pulverizing the soil to form the necessary seed bed, but, unless a certain period is allowed for the soil to "mature," or, in other words, to permit of the necessary plant food becoming available for the needs of the crop, it is im- possible to secure a full return. This point is not at all difficult to demonstrate. It is only nec- essary to take a quickly maturing crop, such as Panicum, and watch results. As an example, I will relate one experience of many I had, showing the effect of early and late preparation. In a field of 30 acres, 10 were plowed four months ; 10, two months ; and 10, just previous to planting. The whole area was planted with Panicum at the same time. The result in green material cut for silage was : for the four months, 12 tons per acre ; for the two months, 6 tons per acre ; and for the portion plowed previous to planting, nil. Although the weather was very favorable during the growing period, the seed on the freshly plowed area practically refused to germinate — only a few small patches appearing where timber had been burned off. This failure of seed to germinate when sown in newly-plowed land, more especially where the soil is of a stiff character, has often been observed. Germination will eventually take place, but it may be weeks or months later. Numerous ex- amples of a similar nature were to be met with in the 1911 wheat crop, and to a lesser extent during the past season. In every dis- trict individual fields were to be met with giving a good yield, while adjoining areas were practically a failure. On investiga- tion it was discovered that, in almost every instance, early prep- aration of the land was responsible for the successful returns. HAMPTON INSTITUTES WORK FOR NEGROES. Hampton Institute's remarkable results in training negroes are vividly set forth in the forty-fifth annual report of the principal, just made public. From a school of IS pupils and two teachers, the Institute has grown into a busy educational village of over a thousand persons, with a far-reaching influence, not only for the races it is designed to aid, but for the whole nation, which benefits by the splendid work and example of Hampton graduates every- where. Industrial training is the keynote of the Hampton success, ac- cording to Dr. P. P. Claxton, United States Commissioner of Education, who is keenly interested in the Hampton work. It is noteworthy that this industrial training is of the most immediate and practical sort, applied to the ordinary producing tasks of life, 235 first of all in the educational plant itself. At Hampton practically all the work is done by the students themselves. There are build- ings to be kept in repair and occasional new buildings to be erected; there is a farm of 600 acres to be cultivated, with 150 cows and young stock, 40 horses and mules, hogs and poultry. There are horses to be shod, harness to be kept in repair, wagons to be built, boys to be clothed — these are a few of the industrial opportunities which the plant itself offers. La§t year the stu- dents received over $86,000. in wages, of which about one-fourth went to the girls for domestic work in the Institute. This year the boys of the trade school have built Clarke Hall at a contract price of $26,142. The work called for the services of bricklayers, plasterers, carpenters, sheetmetal workers, steam- fitters, plumbers, cabinetmakers, electricians, and painters. The architect who designed the building, after inspecting the brick- work done by the boys, said it compared favorably with similar work by New York men; and some of the local builders pro- nounced it the best piece of work done in that section of Virginia. At Hampton work is considered a privilege ; in fact, one form of punishment is the taking away of work from a pupil. No student is ever punished by being forced to work. At the same time, labor is not insisted on as an end itself, but rather as the means to an end. "The aim of Hampton, " says Dr. George P. Phenix, vice-principal, "is not merely to train workmen, but to educate men and women who shall stand for the best things in the communities to which they return, and who can make their skill contribute to this end. ,, MATERIAL FOR MAKING PAPER, Wood-pulp is by far the most important material for making paper at the present day, and, owing to the wide distribution of the sources of supply — coniferous trees being the most suitable — it is the cheapest. Large quantities of straw-pulp also are im- ported into this country for the manufacture of brown papers and straw boards ; and bamboo is coming into prominence as a source of paper-pulp. A new material for making paper, "elephant- grass, " from Uganda, is now suggested in an interesting article published in the current quarterly issue of the Bulletin of the Im- perial Institute. This is a perennial grass, growing usually to a height of 6 ft. to 10 ft., and much higher on rich marshland. Occurring in a deep zone across tropical Africa, it is found chiefly along watercourses and in marshy depressions; but it grows also in the more open parts of bush and forest land. Both cattle and horses eat it readily. A sample of the dried mature grass was sent recently from Uganda to the Imperial Institute, with the object of ascertaining its suitability for the manufacture 236 of paper. The Chief Forestry Office of the Protectorate stated that the grass was a source of annoyance and expense to agricul- turists, as it grew rapidly after the aerial shoots had been burnt or cut down; but that, if it could be used profitably for the manu- facture of paper, a new and large industry could be built up. Since this grass is available in immense quantities, and at present has to be burnt each season in order to keep it down, it is im- portant to find a commercial use for it. The consignment, which weighed 177 lbs. when received at the Imperial Institute, and 145 lbs. on being air-dried, yielded, after treatment in the laboratories, a pulp of good color, composed of ultimate fibers rather longer than those of esparto grass and about the same length as those of bamboo pulp. It furnished a fairly good paper. Owing to the light and bulky nature of "elephant grass," however, it is unlikely that the stems could be shipped profitably to Europe for paper-making; but if the stems were converted into pulp at or near the sources of supply, by treatment with caustic soda, it is possible (in the opinion of experts) that a remunerative industry could be opened up, since the pulp prob- ably would be approximately the same value for paper-making as wood-pulp prepared by the soda process — namely, £7 10s. to £8 12s. 6d. per ton in London (February, 1913). Since there are immense deposits of soda in East Africa which could be utilized for the manufacture of pulp, there would appear to be some prospect of a new industry's growing up in this Protectorate. — The Mail.
