Vou. XXXII, — COLOMBO, JANUARY 15rx, 1909, No. 1. Capital in Agriculture. ‘As we have shown in detail in a book upon Agriculture in the Tropics, shortly to appear, progress in agriculture proper depends first upon progress or proper equipment in what we may call the preliminaries to Agriculture, These are. roughly : (1) land, (2) climate, (8) popula- tion and labour, (4) transport, (5) capital or money, (6) drainage and irrigation, (7) tillage, (8) education, and (9) crops. Now land, climate, population, trans- port (to a very large extent), irrigation, tillage (to some extent), education (to some extent), and crops are satisfactorily enough arranged in Ceylon. There remains capital. Asa late President of the United States remarked, finance and transport are the keys of progress. So convinced were we that this was th® only sound order in which to deal with agricultural problems, that the very first paper read at the first Meeting of the Board of -Agriculture was by ourselves on Co-operative Credit Societies, and we have preached this doctrine to some- what unwilling ears ever since, and have had something about it in practi- cally every number of the ‘‘T.A.” The tide is beginning to turn, and the Society is displaying an _ increasing interest in this question. It must be clearly recognised that no serious pro- gress is possible without money, but once the expenditure of money is started on the right lines, it breeds more money. At present the - villager is helpless in the grasp of the local money lender, and cannot afford to borrow a penny even if he thinks it probable that it might bring in twopence or three- pence. Manuring of rice, transplantation of rice, cultivation of vegetables, manur- ing of coconuts, sale of produce outside the village, and all other suggested im- provements demand money for a start. Mr. McCall gave some interesting facts about Egypt at the last Meeting of the ' Board. There are no white planters there, and at first the natives were averse to manuring ; but, once convinced by ocular demonstration that it paid, and provided with the necessary money by Agricultural Banks or Soci ties, they took it up so strongly that within four years Egypt was consuming £175,000 worth of artificial manure a year. If the Ceylon villager is not to sink to the position of a hewer of wood and drawer of water, he must be helped to get financially upon his legs, and the new Government departure of loans to the agriculturists will be watched with great interest. How best to give security for the money will be one of the problems. It has been suggested that headmen, who are commonly men of more or less substance, should give the security, and lend to their villagers in cases where they feel that is safe. But so many villagers merely lease the land on which they work that there may be difficulty about the security, As Government is now going to attend to the money question with regard to paddy cultivation, we would recommend that the efforts of local societies be di- rected to other crops, to their establish- ment, their cultivation, tillage, and man- uring, and their sale in the best market. For all these ends money is necessary. There is an enormous difference between the agriculture of planters’ estates, whether European or native, and that of the villager—the former / [JANUARY, 190% getting a larger return at less cost. But it must not be supposed that this is all due to the superior Education or training of the former; rather it is largely, at any rate, to be attributed to the fact that he has capital at his back. It may be well to remark that there are other preliminaries to agriculture, conspicuous among the.a being trans- port, and it will be idle to expect much progress in a village unprovided with roads. Here the most that can at present be hoped for is that the villager should get free of the incubus of debt. Education, again, is very important. Travelling about the country, and noting the signs of agricultural pro- gress, new crops, &c., and enquiring about them, we have very commonly found that they owe their origin to the local school garden, and are often, in fact, cultivated by a boy being educated — at the school. Tillage isa thing as yet mainly prac- tised in paddy-fields, but nothing can be done in the way of improvement with out money for a start. JANUARY, 1909.} | GUMS, RESINS, SAPS AND EXUDATIONS. CASTILLOA OR CENTRAL AMERICAN RUBBER. By WILLIAM FAWCETT, B.SC., F.L.S., Late Director of Public Gardens and Plantations, Deputy Chairman of the Agricultural Society, Jamaica. Para rubber (Hevea brasiliensis) has supplied such a very large proportion of the rubber used in the arts, the area of its natural habitat isso vast, and the tree has been planted so extensively, that the attention of growers of rubber has been mainly directed to experiments with italone. But, as the conditions for the successful cultivation of the Brazilian tree are not to be found everywhere in the tropics, it is well to experiment also with other plants, and the most pro- mising of these is perhaps the Central American rubber, a species of Castilloa. Species.—Some species of this genus, e.g., Castilloa tunu, are worthless as producers of rubber, and before using the seeds of any Castilloa. tree it is important to ascertain whether the latex of that tree yields rubber of good quality. Castilloa elastica is the species that has been considered the main source of Central American rubber. Professor Olsson-Seffer thinks that Castilloa luctiflora gives a more ample flow of latex. It is to be honed that he will favour us with the results of further investigations. Situation.—Experience in growing Castilloa under various conditions in Jamaica points to several factors as being important for the _ successful growth of the tree. It will not grow to advantage if the proportion of clay in the soil be too high, otherwise it does > not appear to be very particular. A loamy soil is the most suitable. The drainage must be good; the unsuit- ability of stiff clays may be due to the want of sufficient drainage, and may perhaps be overcome by making drains. The rainfall should be at least 70 in. per annum; but if less, and the deficiency can be supplied by irrigation, the trees will grow and yield quite as well. A tem- perature which varies between 70° and 90° F. is suitable; the elevation is not material if the temperature does not fall much below the lower limit. Shade.—Castilloa trees are found in nature on the edge of forests and in clearings. Overhead shade is not re- quisite in the wild state, and has not been found essentialin plantations. The stem requires some protection from the sun, but this can be provided in plan- tations by the shade of the neighbouring trees. Overhead shade is not detri- mental if not too dense, but it lengthens out the bole of the tree unnecessarily. Clearing Ground,—If woodland has to be cleared, this operation should be done thoroughly from the first. Some recommend thata few trees should be left here and there to afford shade for the seedlings and young trees, but they must be got rid of eventually, and the cutting down and removing them leads to injury and destruction among the rubber trees. The large trees should be sawn into boards for the erection of sheds at a later period; the smaller timber will be useful as posts ; the small useless branches should be heaped and burned in such a manner as not to set fire to other trees or bush close by. The ashes are good manure, Distance apart and Catch Crops.—The distance at which Castilloa trees should be planted at first depends upon whether they are to be grown with bananas or other catch crop, or alone. If the soil is suitable for bananas, and the locality one where it will pay to grow them, no other catch cropis anything like as good. The bananas should be planted in March at distances of 15 ft. apart, and the Castilloa seedlings may be put out about September, each seed- ling in the centre of four banana plants, or, if the cultivator or plough is used to keep down weeds, the Castilloa must be planted in the banana rows between the bananas. The bananas may be grown for three or four years, and then they should be gradually thinned out as the Castilloa trees spread their branches. If bananas are not suitable, corn (maize) and gungo or pigeon peas (Cajanus indicus) may be used as catch crops and temporary shade. The fields should be lined out in March, and stakes put in to mark where the Castilloa plants are to be put out. Then the gungo peas should be sown so as to leave a clear space of 4 ft. round the stakes, and the corn not nearer than 7 ft. The gungo peas will not last more than two or three years, but by that time the young Castilloa plants will not require any more nursing: The corn will not inter- fere with the Castilloa if kept ata safe distance, and if there is a market for it the returns will help to pay expenses. Even if there is not a market for the gungo peas, they will increase the introgen content of the soil, besides Gums, Resins, forming a slight shade for the rubber. The cultivation of the soil will be of the greatest benefit to the growing rubber plants. If no catch crops are to be grown the distance for the rubber plants may be 6 ft. at first, to be thinned out eventually to 18 ft apart. Seeds.—The seeds are massed together, and are covered with an orange-coloured flesh. When ripe they drop from the trees, and if left undisturbed numbers of seedlings will soon spring up. Itis best, however, to collect themas they fall, and sow them ina seedbed. There should be no delay in sowing them, for they soon lose their power of germin- ating. Professor Olsson-Seffer was in- terested in some experiments to deter- mine the best ageat which to collect seeds from the trees. Until the result of these experiments is known, I should advise that seeds should not be sown from trees until they are fully six years old, when the latex has lost its resin. Sowing Seed.—The seed-beds should be thoroughly forked and raked until the particles of soil are quite small and fine. The seeds should be lightly pressed down so as to be just covered by the soil, and at a distance of about an inch apart from each other. A thin layer of dry grass may be scattered over the bed, and then a good watering given from a watering- pot with a fine hose. The soil should afterwards be kept only just moist. not too wet, and carefully weeded. When the seedlings are 3 or 4 in. high the soil may be loosened with a fork and the seedlings taken out, and either planted again in boxes ata distance from each other of 3in., or set out at once in their permanent places in the field. If they can be constantly inspected in the field and kept weeded, and the weather is favourable, itis better to put them out at once; but if not they may be kept in the boxes until they are6or7 in. high, and then transplanted, when they are not so liable to be the worse for any neglect in the open. It is still better to sow the seeds at once, as _ soon as they fall, in the permanent positions already marked out for them in the field. Three or four may be sown at the stake at about 3 in. from each other. Planting out.—If bananas have already been planted during the previous March, the fields should meantime have been run over with the plough or cultivator to keep down weeds, and to establish a dust mulch on the surface. The seeds may be sown as they fall, or the young plants may be put out about September, either in the rows between the bananas, so as to be 1a ft. apart when the bananas are removed, or they may be planted each in the centre of four bananas. [JANUARY 1909, Thinning out.—The seedlings should be continuously watched and carefully thinned out, leaving at the end of the first year only the most promising one at each stake. If none of the three or four has turned out well, supply from the nursery which had been made for the purpose.—Tropical Life, September, — 1908, Vol. IV., No. 9. THE RUBBER TRADE OF BRAZIL. Ceylon rubber producers will be in- terested in a comment which appears in the Board of Trade Journal upon the trade in Brazil, Referring to the ready disposition shown among British capitalists to invest in the acquisition of Brazilian rubber-producing properties, the Journal shows that investments of this nature have not invariably been successful, and advises that such under- takings should be entered into with the greatest circumspection. It is pointed out that the remarkable develop- ment of the rubber trade in Ceylon and the Straits Settlements, as well as in Africa and Mexico, has made a great change in the position, and is likely to change it still further. Up to this time Brazilian producers have apparently attached little importance to possible competition from these sources, but now some among them are beginning to view the matter as fraught with more danger to the interests of their industry than they had supposed. It is even argued that within a period of ten years the practical monopoly of Brazil in this important and increasingly valuable production may be at an end. The Board of Trade commentator says it certainly appears that, other conditions being favourable, the systematic process observed in the countries named, to- gether with the greater cheapness of labour, transport, and other items affecting the industry will place these cultivators in a vastly superior position to those of Brazil, where the expenses in every branch of the industry are on an extremely high scale, and where the risks to health in the process of collection, with other contingencies, constitute a heavy handicap.—-Indian Agriculturtst, Vol. XXXIII, No. 9. CASTILLOA ON THE ISTHMUS. OF TEHUANTEPEC. By J. L. HERMESSEN, of Chiapas, Mexico. (Continued from page 513.) Much stress has been laid upon the danger, in tapping, of cutting through | the cambium layer into the wood; and 7 ‘gh a ‘9 BY, * JANUARY, 1909.] it cannot be denied that incisions around the circumference of a tree, of such depth as to penetrate the cambium layer throughout its entire length, is apt to cause rot, in which certain insects are likely to deposit their ova, the larve proving in many _ instances destructive of, or at least injurious to, the trees,—this being particularly the caso where the “machete” was used as the tapping instrument. But with a modern tool of such design as_ to prevent too deep an incision being made, it has been found that a cut just impinging upon the cambium layer, and piercing it only at intervals, has not only given, the greatest amount of latex, but seems to be necessary to the formation of new bark. Any incision failing to reach and penetrate, at in- tervals, the cambium layer will result in a mere hardening of the surface of the cut without any attendant renewal of the bark. It has been noted by many that the touching or cutting of the cambium layer effects a restoration or new growth of the bark within a period of sixty days, the bark continuing to grew and fill up the entire incision within a year. Doubt yet exists as to the best time of the year in which to conduct tapping operations. Mr. James Collins, in his Report on the Caoutchoue of Commerce, published in 1872 under the auspices of the British Government, states that in Niearagua (where the climatic con- ditions are generally similar to those obtaining on the Isthmusof Tehuantepec) the most favourable time for tapping was during the months of March and April, when the change of foliage was taking place. The following quotation from Mr. O. F. Cook's monograph on Castilloa* also bears upon the point: “The indications are that (internal) pressure attains its greatest intensity in trees which are exposed for a part of the time to a relatively dry atmosphere, and which are accustomed, as it were, to pump water rapidly to supply the leaves. Such trees may, onthe contrary, yield no milk at all when the water supply is deficient. It may be expected, therefore, that open culture will require much more careful attention to the time of tapping.” The best results, thus far, have been obtained on the Isthmus of Tehuantepec from tappings made during the early months of the dry season (Febuary and March), before *“The Culture of the Central American Rubber Tree.” By O. F. Cook, Botanist in charge of Investigations in Tropical Agricul- ture, United States Department of Agriculture. ' Washington, 1903. 5 Saps and Excudations the weather has become very hot and when the coolest nists and mornings occur. In April and May, when the maximum temperatures of the year are attained, the deciduous character of Castilloa becomes most marked ; and this is the period during which the tree is generally supposed to be in its most quiescent state, and to have the last recuperative power. On the other hand, in the wet season planters are confronted by the physical difficulty of collecting the latex. Some contend that tapping can best be done durin the occasional (and very uneertain) rainless spells of the wet season; an it is upon the latter hypothesis that two tappings per year for Castilloa come within the range of possibility. It has been noticed that the latex is in a much more fluid condition during the early morning hours, turgescence increasing as the diurnal heat reaches its maximum. What the financial promoter and the expert prospectus-writer had long since settled to their own entire satisfaction and that of a trusting public, with the same fatuous positiveness as your orthodox theologian dogmatises on the future life—the question of yield—is still to the planter, who should know most about it, largely a sealed book. If he be honest, he will confess that he knows as yet very little aboutit. What he does know, however, is thata_ six- year-old tree will not give 1 Ib. of rubber. Trees of unknown age, in a state of nature, have yielded as much as 4 and 51b. of rubber at one tapping ; and there are apparently well-authenti- cated records of yields of triple that quantity from very large and presum- ably very old trees. Undue weight seems to have been attached to the generalizations of Herr Th. F. Koschny, of Costa Rica, in this respect. Hisclaim, for instance, of a yield of 33 lb. of rubber from wild trees, 8 or 9 years old must be accepted cum grano salis. There are, as a matter of fact, no recognised means of definitely determining the age of wild rubber trees; the all-important element in the case in point is, therefore, hardly more than one of conjecture. With regard to cultivated trees, whose ages, with very few exceptions, have not yet passed the eighth year, there appears to be a strong disinclination on the part of planters in Mexico to tap their trees to the full extent of their possibilities, owing mainly toa reasonable fear that permanent injury may result through incautious tapping in the light of present knowledge; and since in the case of Castilloa, as with all caoutchouc-produc- ing genera, notable constitutional dif- Gu ms, Resins, ferences occur, both as to size of tree and yield of latex, under similar cultural conditions, the results obtained from individual trees do not form satisfactory evidence upon which to base a conclusion as to the average yield of many thousands of trees of like age. Hence, trial tappings of single trees, or groups of limited number, of equal age vary very consi- derably. Thus, we have trees, or groups of trees, producing 1, 2 and 3 oz. of rubber, others ranging as highas from 4 to6oz. at one tapping. With such vari- able data to go upon, the difficulty of arri- ving atatrue average yield for a planting of perhaps half a million trees is obvious. Tentative experiments made in this district would indicate that trees grown under the most favourable conditions of soil, &c., may be tapped twice a year with equal results; but it would seem premature to say with assurance that the trees covering a large area could be safely subjected to such a drain upon their vitality until they had attained a greaterage. Torepeat, however, selected groups of trees of the age above men- tioned have withstood a second tapping in a year without visible injury. With regard to local soil conditions, it has been stated that ‘‘ the oldest portion of the Isthmus evidently began its superaquatic existence at.a compara- tively recent period—geologically speak- ing ”’*—.and that much of the geological formation of the Eastern Atlantic versant of the Mexican cordillera to- wards the Isthmus of Tehuantepec is of similar late origin is indicated by the presence of stratifications of marine shells and primordial ooze, where sub- sequent aqueous erosions have occurred, creating, in the cycle of topographic changes, more or less abrupt undulations, ridges and valleys, with occasional hills reaching to a height of 150 ft. between depressions. In the immediate neigh- bourhood of the sea and the riverine estuaries alluvial deposits are found, but these have proved unsuitable for most cultural purposes, owing to the shallow- ness of the water basin. On theapproach to the sierras, ‘‘mesas,” or benchlands, occur of an entirely different structure, these being made up of granitic or other primitive detritus, incorporated with abundant vegetable matter. Such lands, unfortunately, are not encountered in any large areas. The soil of the district herein referred to is composed of clayey loams, overlaid in parts with beds of rich black humus of the greatest fertility. * «© Report of Explorations and Surveys for a Ship Canal by the way of the Isthmus of Tehuantepec.” By Robert W. Shufeldt, cepien, United States’ Navy. Washington, 2 “ae 3 6 [JANUARY, 1909, The climate of the Atlantic side of the Isthmus of Tehuantepec has three well- efined seasons-—namely, the wet season Proper, commencing usually the last week In May or the first week in June, andcon- tinuing till the end of October ; the lighter wet or “norther” season, extending over the months of November, December, January and February; and the dry » season, comprising the months of March, April, and May. The annual rainfall is between 90 and 120 inches, with a very favourable distribution, three-fourths of the total precipitation taking place between June and October, while from then on until the approach of the dry season frequent showers fall, with much mist and drizzle. No month of the year is wholly free from rain, occasional light showers occurring even during the height of the dry season, when the greatest heat of the year is experienced, the Mercury fluctuating between 80° and 90° F. in the shade, and sometimes marking 100°. Anappreciable diminution in temperature ensues dur- ing the wet months. the average range being from 75 to 85° E., while during the cooler months, from November to February, the average temperature is between 60 and 80° F., once ina while falling as low as 55° F. in the early hours of the morning. The lowest temper- ature recorded by one observer over a period of nine years was 50 occurring in the month of January. .The relative salubrity of the climate of the Isthmus of Tehuantepec as a whole, as compared with that of similar latitudes elsewhere, is quite remarkable, this continent being cooler under the equator than any other, owing to the expanse of sea surrounding it and the more elevated configuration of the land. The vegetation of this region presents to the trained eye a strictly tropical aspect, the forest growth consisting almost entirely of tropical genera, such as mahogany, Spanish cedar, lignum vitae, giant representatives of the ficus family, the stately ceiba, with its wide- spreading, buttressed trunk; numerous examples of sapotaceous trees, ineclud- ing the lofty ‘‘Mamé” and the “chicle”’ (from which American ‘‘chewing-gum ” is made, and which also produces one of the best of all wild tropical fruits, ~ namely, the ‘‘zapodillo,” or, in the verna- cular ‘‘ chico zapote”); while many ano- naceous trees-occur, some of which bear edible fruits—close relatives of the famous custard apple, or ‘“ chirimoya.” Hard-wooded shrubs of various orders, and large-leaved plants from the under- growth, with scattered groups of deli- cate slender-stemmed palms, belonging principally to the genus Chamoedorea. F., this’ JANUARY, 1909. } Sheltered in the ravines, and generally near the edge of a water course, tree ferns add their feathery beauty to the leafy labyrinth of the jungle, notwith- standing the low elevation of 300 feet above sea-level. Clustering the more open parts, and fringing the banks ot rivers and streains, are groves of tall, graceful palms, incluc- ing Attatea cohune and the spiny Acro- convia; while now and then a royal palm (Oredoxa regia) rears his noble head over legions of lesser kind. (The writer is informed by a friend, who is more than an amateur botanist, that he has identified fourteen indigenous specimens of palm on the Isthmus of Tehuantepec.) Interlacing with fantastic festoons the upper branches of big trees, or reaching, like the halyards of a ship, to the earth, are great lianas, or climbing vines, which, when in flower, display enchant- ing colour effects, clothing the tops of the highest trees with brilliant mantles of purple, yellow, and crimson. These seem to be made up chiefly of representa- tives of the Leguminose and Bignonia- cece. Many trees, again, are adorned with a profusion of epiphytic growth— ferns, bromelias and orchids. Amongst the latter may be found Chysis bractes- cens, with its beautiful, waxy-white sepals and petals, and labellum tinged with yellow; the pretty and fragrant Epidendrum atropurpureum, H. cochlea- tum, EH. alatum, EH. radiatum, and &. stamfordianum ; a species of Oncidium very similar in foliage and inflorescence to the well-known O. cebolleta (found at higher altitudes in Mexico); O. luri- dum, MB sphacelatum, one or two showy species of Stanhopea, anda number of other genera of merely botanical interest. Four indigenous species of vanilla, including V. planifolia, also have their habitat in these forests. No attempts have been made, however, to cultivate the plant here.

The following particulars relative to the rubber industry of Japan have been received by the Board of Trade from the British Commercial Attaché at Yoko- hama (Mr. HK. F. Crowe) :— The Osaka Asahi publishes an article dealing with the proposed establish- ments of two rubber factories, in which British, French, and Japanese capital will be invested. From this account it appears that a Frenchman who is in- terested in various other enterprises in Japan has arranged a combination with two British companies. One factory will be situated at Osaka and will make tyres and other rubber goods, while a smaller factory will be built at Kobe for the manufacture of rubber tubes for feeding bottles. The idea is to start with a moderately small capital of £75,000; as the business develops it is proposed to increase the capital and to start exporting rubber goods to China, Korea and other Eastern markets At the present moment there are six rubber companies in Japan with a total capital of £45,000. Of these the oldest and largest is the Japan Rubber Com- pany of Tokio, started in 1900 and having a capital of £18,000. The others are as follows :— Name. Town, Capital. Tokio Rubber Co.

THE FUTURE OF THE CAMPHOR TRADE. Hor some time past the cultivation of the Camphor tree for commercial pur- poses has been carried on, even in For- mosa, its native country, under the fear of a diminishing _ trade. Synthetic camphor has been talked about for many years past, and, like the chemical pro- duction of indigo, which has threatened the Indian planters. with extinction, there has been and is still the fear of the triumph of the chemist over the planter in the future supply of the Camphor market. Incidentally it may be stated that under the new Patents Act, which came into operation recently, a factory has been erected chiefly for the chemical manufacture of indigo by a German firm on the Manchester Ship Canal near Chester, and no one can tel how soon a similar factory for the pro- duction of camphor may follow. The competition between the two. kinds of camphor is sufficiently apparent, when we find both products side by side in the London market, with a strong tendency by the makers of the synthetic product to bring the prices of their article considerably below those of re- fined natural camphor. With the pre- sent camphor supply in the hands of such shrewd commercial people as the Japanese, and with the introduction of the Camphor tree into various other countries, a process that has been going on for several years past, the future of the European trade has become a kind of Chinese puzzle. Thus the Japanese Minister of Finance, in an official report issued a short time since, drew attention to the circumstance thatif Japan wished JANUARY, 1909. ! 9 to retain the control of the camphor trade in future years, and to meet the ever-increasing demand, she must bestir herself by extending the cultivation of the tree, which requires forty or fifty years’ growth before avy satisfactory return can be expected. Hefurther said that, while thus encouraging the pro- duction and manufacture of camphor, the Government intended also to promote the exportation of the finished article, and commissioners had been sent to Kurope and the United States to investigate the conditions affecting thedemand, About the same time that this Report was issued a statement also appeared from the United States Consul at Tamsui, of an interview with the chief of the Camphor Bureau of Formosa. it is stated that the manufacture of camphor in Formosa affects only those trees of fifty years old or upwards, inas- much asthe cutting down of trees of a less age is forbidden. Recent investiga- tions indicate that the supply of mature trees will, at the present rate of cutting, become exhausted in less than fifty years. The old trees now standing are confined to the mountainous eastern half of the islands in regions, for the most part, inhabited by savage tribes. These mountains are covered with dense jungles, and the work of making roads, in order that the camphor forests may be rendered available for profitable exploitation, must involve the expendi- ture of much time and labour, besides which the sanitary conditions of the country are such as to produce fever among the labourers. A thousand coolies _were taken by a Japanese company into the Daito prefecture a few years ago for the purpose of exploiting the camphor forests, and 33 per cent. of the workers were completely incapacitated by fever. The greater part of the camphor at present produced in the Island comes fromthe Toen prefecture. Between 1900 and 1906 the Japanese Government planted about three million young trees, and it is intended to follow this up by planting 750,000 in each successive year. There are said to be two distinct varieties of the Camphor tree grown, one prodacing the camphor of commerce and the other producing only camphor In this . Saps and Hxudattons oil. There would appear, however, to be some mistake in this, as will be seen later on. Private firms in Formosa wishing to engage in the cultivation of Camphor trees are supplied with young plants from the Government nursuries. Al- though the Customs returns for China show that 12,000 piculs of crude camphor were exported from that country in 1906, yet the Kormosa authorities fear no competition from that source, and the reports of camphor planting in Ceylon, Florida, Texas, aud Mexico do not disturb the prospects of the Formosan product in the eyes of the authorities. They contend that the more Camphor trees planted the less likelihood there will be of the successful production of an artificial substitute. The subject is interesting from two points of view, First, it must be remem- bered that pharmaceutically genuine or natural camphor is alone acknow- ledged by the British Pharmacopoeia, while synthetically-prepared camphor is principally and increasingly in demand for the manufacture of celluloid and smokeless powder. Referring to the statement that two varieties of the Camphor tree are grown in Formosa, one yielding camphor and the other camphor oil, we may quote from a recent report of Sir A. Hosie, Acting Commercial Attaché to H. M. Legation at Pekin, where he says ‘‘ Not only is camphor distilled from the camphor wood chips upcountry, but the oil resulting from this distillation is brought to Foochow in airtight old kerosene tins, ve-distiiled, and made to yield some dC per cent. of its weight in camphor.” The process is described as a very crude one, the oil being poured into the retorts, and the distilled oil, after passing through the worm, is received into kerosene tins, which are placed in tanks ot water, where they stand for twenty- four hours to cool and to deposit the camphor in the bottoms of the tins. “The oil 1s then poured off and redis- tilled as many as sixteen or seventeen times, until the camphor has all been extracted.”—Gardeners’ Chronicle, Vol. XLIV., No. 3538, October, 1908. 10 vis (JANUARY, 1909. OILS AND FATS. RECENT RESEARCHES REGARDING THE GERMINATION OF THE COCO- NOT AND THE DETERIORA- TION OF ITS PRODUCTS. ABSTRACT BY C. DRIEBERG. The latest issue of the Philippine Journal of Science contains a series of notes on the sprouting of the coconut, on copra and on coconut-oil, which ought to prove of interest to the planter. The first of these notes treats of experiments made witha view to discover if the coconut, like the castor-oil bean and many other oil seeds, contains a fat-splitting enzyme capable of saponify- ing outside of the growing nut. A large number of tests were carried out, the details of which it would hardly prove of interest to traverse, but the result of seven months’ work in this connection was tothe effect that there was not the slightest proof of the existence of such an enzyme. The cause of the destruction of the fat which takes place in the growing nut has, therefore, to be sought for else- where. The second note deals with the changes accompanying the sprouting of the nut. As regards the milk—or, as we eall it, the ‘‘ water ”—(for coconut milk is, with us, the expressed milky juice of the meat or flesh) the total quantity showed a marked diminution from 374 grammes in an unsprouted nut to noth- ing when the sprouts had attained a height of 93 centimetres. At the same time there is a decided loss of sugar, which falls from 2% and 2°3% in the milk of unsprouted nuts to 8% in that of the nuts with sprouts 88 centimetres in height. In the meat or flesh a definite loss in total weight is evident, since it drops from 475 grammes in the unsprouted nut to 148in the nut with sprouts 93 centimetres high. The loss appears to be due to direct absorption by the foot, the process taking place at first only in the portion of the meat near the latter, but increasing rapidly as the endosperm grows larger and comes in contact with the entire inner surface of the nut. The loss in weight of oil is fairly propor- tional to the loss in weight of meat, the percentage of oil in the meat remaining constant within the somewhat wide limits of individual variation. During the early stages of germination there is apparent a certain concentration of oil near the foot, with corresponding loss in that portion of the meat farthest away. Water is gradually lost by the meat, as well as all other parts of the nut, by evaporation through the shell and sprout during germination. The percentage of sugar decreases from 4% % in the unsprouted nut to 1:12 % in that with a sprout 938 centimetres long.. The loss is probably to be attributed to absorp- tion of sugar by the foot, as in all cases there is considerably less sugar in that portion of the nut in direct contact with the endosperm than there is in the parts farthest away from it. As regards crude fibre in meat no decided change in the proportion can beobserved. Itis absorbed at practically the same rate as the rest of the meat. In the observations regarding the changes taking place in the foot, it was found that the total weight increased from 19 grammes in the unsprouted nut to 228 grammes in those with a sprout 93 centimetres high. There was apparently also a loss in the percentage of sugar (although not in its total weight) until the foot completely filled the nut, at which time there is rapid gain. This phenomenon is probably to be attributed to the fact that the foot at first draws its sugar chiefly from the milk, by which it is almost entirely summoned. How- ever, as it continues to grow, it soon exhausts the sugar in the milk, and only when it has completely filled the nut and come into intimate contact with the inner surface of the meat, has it an opportunity to continue the process:of sugar absorption and also of sugar creation, possibly from the oil, or possibly from oil and erude fibre. Ot crude tibre there was only a slight . increase to be noted. From the commencement of the ger- minating process oil from the meat near- est the foot is invaiably richest in fatty acids, and this difference becomes more marked as germination proceeds. It is only when the foot has come in complete contact with the meat that an increase in fatty acids throughout the whole nut is observed, indicating that oil, to — be in a condition for absorption, must be hydrolised. This hydrolysis may 1 gramme = 15°43235 grains. 1 centimetre = 3937 inches. JANUARY, 1909.] take place as the result of an enzyme in the foot, or be caused by one in the meat, which is dormant until rendered active by some product of metabolium in the foot. It is, however, not possible to prove by an _ increase in free fatty acid the presence of any fat-splitting enzyme in the coconut. Such an enzyme may exist, but under such conditions that any large excess of free acid must be used up by the growing plant before the process can continue. To summarize ina word the changes, determinable by chemical analysis, in the growing coconut :— Oil is lost by the meat; it is not taken up as such by any other portion of the nut, but is either oxidised to furnish energy for the growing plant, or is split up and transformed by progressive synthesis into sugar and finally into cellulose. Sugar is lost by meatand milk, but a corresponding quantity is gained by the foot, the total quantity in the nut remaining approximately the same. Asmall amount of crude fibre is lost by the meat, but a much larger quantity is produced in the sprouts and roots. Note 3 deals with the action on copra of micro-organism in pure culture. The Philippine Journal in 1906 recorded the fact that moist copra is attacked by micro-organisms with consequent splitting up and destruction of the oil —this action being most pronounced when the copra contains from 10 to 15 per cent. water. Under these conditions the growth of mould predominated largely over that of the bacteria. With a much larger percentage of water, and when the bacteria were in excess of the moulds, the destruction of fat is greatly diminished. These observations led logieally to the conclusion that hydro- lysis of oil in copra was due to mould action alone, although the then available data did not exclude the possibility of symbiosis and interdependence, in this fat-splitting process, between moulds and bacteria. Dr. Edwards of the Biological Laboratory of the Philippine Bureau of Science, in pursuing further research into this question, separated some fifteen different organisms from mouldy copra and coconut meat, and finally succeeded in isolating in pure cul- tures the majority of the growths present. The identification of every organism was found to be impossible, and indeed the majority of them are probably new and undescribed. However, the main object of the experiment, viz., the differentiation between moulds and bacterial action has been accomplished. 11 Oils and Fats. Taking the total weight of dry copra, every active mould culture brought about a decided loss ranging from 5 to 11 per cent., while only one bacterium was found to cause any appreciable loss, The moulds destroy a certain percent- age of the oil, and the greater portion of the loss is attributable to this cause. These losses, which represent 8-9 to 19:9 per cent. of the original weight of oil, are accompanied by hydrolysis with the formation of fatty acids and glycerine. There seems to be no direct relation between the percentage of free fatty acid evolved and the total quantity of oil destroyed at the time, since low as well as high precentages of free acid show the same loss of oil. As already mentioned, only one bacterium caused diminution of oil, and this only to the extent of 4 grammes, which is less than that brought about by the mould with the weakest action, and the loss isnot accompanied by hydrolysis in this case, On the other hand, one bacterium appears to have caused a slight gain in total oil. The sugar is almost completely destroyed by all moulds, whereas bacteria may be said to produce no effect here. Looking at this matter from a com- mercial standpoint, it may be stated that mouldy copra must have suffered a loss in total oil-content which may reach the neighbourhood of 20% under the most favourable conditions, but certainly to an extent to be taken into account in the purchase of such copra. Such inferior produce undoubtedly cannot give as good a yield of oil as that which has been carefully dried and preserved. On the other hand, in the case of badly cured copra, if a sufficient quantity of water (about 15 %) is present, it is bacterial action and not mould action that will come into play ; so that no diminution of oil would be observed, though bacteria so disintegrate and change the copra thataslimy soft mass characterised by an objectionable odour, and difficult to work so as to procure pure oil reasonably free from acid, results. In the Philippines a large amount of copra is dried by means of fires in pits, the meat being placed on bamboo gratings above and the fuel beneath. It is not impossible that the smoking to which the copra is subjected has a slight antiseptic action which would tend to diminish the subsequent growth of oi1ganisms, and so to preserve the oil. Nevertheless, the arguments are all in favour of a clean white, prefectly dried copra, which will not afford a medium for the growth of organisms, unless the Oils and Fats. Conditions of shipping it are such as to allow of sufficient absorption of water to acilitate mould growth. To summarise this part of the paper :— Six ditferent moulds, any one of which is capable of hydrolysing and destroying fat, have been isolated from the many organisms growing on rancid copra. This fat-destruction is part of the life process of the mould, and is independent of bacterial action. Copra acted on by moulds was found to have suffered an almost total loss of sugar. The bacteria found on copra have very little effect on the quality or quantity of oil produced. Their effect is practically to produce _a more or less sour odour and bring about disintegra- tion of the meat. It is good commercial practice to prepare only the best, white, and per- fectly-dried copra. The fourth and last note deals with the production of freeacid in commercial coconut oil on long standing. Thirty- five samples of oil of various conditions were examined, and the table of results provided show the percentage of free fatty acids (as oleic) at the start, and after two months, four months, six months, one year and three years. The conclusion to be drawn may be stated as follows :—The deterioration of afreshly prepared commercial coconut oil is produced by at least three entirely independent processes, and may _ be divided into two distinct periods of time. The first, rapid splitting up of the fat, beginning immediately afterits expres- sion from copra and continuing for several months up toa year or more according 12 it ‘ [JANUARY, 1909. to the nutritive matter present, is occasioned by moulds which are either pressed out with the oil together with sufficient sugars and albuminoids for their growth, or, in the case of hot pressed oils, enter the freshly prepared oil from the air. This action continues as long as sufficient nutritive material for mould growth remains in the oil. It may be completely checked by filtration, preferably after heating to 100° C. more thoroughly to coagulate albuminoids and to destroy any enzymes already secreted by the moulds. Toward the end of this first period, oxidation by the air sets in and may continue indefinitely. The rate of this process depends upon the amount of surface exposed to the air, compared with the total volume of oil, and may in extreme cases cause an exceedingly rapid deterioration. It may be entirely pre- vented by storing the oil in completely tilled receptacles impervious to air. Along with the two above-mentioned processes, a slight hydrolysis, due to heat, moisture and free acids already present, is constantly taking place. reduced considerably by filtration, which removes most of the water, together with the organic impurities, There is reason to believe that some hydrolysis is brought about by enzymes produced by the moulds, as unheated oils which have been filtered and rendered antiseptic increase in acidity somewhat more rapidly than do heated ones under the same conditions. However, this dis- tinction is not so apparent after the first year. Light has apparently no effect on the oxidation by air of coconut oil. It may be . . JANUARY, 1909.] 18 DYES AND TANS. THE USE OF TERMINALIA ARJUNA BARK FOR TANNING. By D, O. Wirt, 1F.s. Until lecame tothe Nimar division of the C. P., the use of the bark of Terini- nalia Arjuna (Kohar) as a_ tanning material was unknown to me. That its use is far from general may be gathered from the fact that no mention of itis made in Watt’s Dictionary of Economic Products, Vol. VI, Part t, page 16, nor in Brandis’ Forest Flora of the North-West and Central India, p. 225, though both authorities mention the bark as used medicinally. Its use would, therefore, seem tobe very restricted and hence of little importance, and in ealling attention to it, it is more with a view to point out a parti- cular form of damage that may be caused to our forests by its use than to assist in turther developing the industry. I will first give a briet sketch of the industry and the methods employed in the use of the bark. It is extensively used by chamars in the Nimar District for the tanning of hides, and especially by the shoe-makers of Burhanpur, a fairly large community, where its use first came to my notice. Removal and Collection of the Bark.— The bark is stripped from the trunk and main branches during the months of - Aprilto June. The period of the year is an important point to which I shall reter later. This time of year is chosen as the sap is then most activein the cambium layer and the bark separates more readily from the wood than when the flow of sap is at its lowest. I need hardly add the collectors strip off the entire bark, and are not in the least con- cerned with the immediate resuit, viz., the death of the tree, Treatment of the Bark.—The bark is then dried in the sun and pounded with mallets until reduced to shreds oras fine a consistency as possible. No further treatment is necessary. It is now ready for use, and is caretully stored away until required, great care being taken not to expose it to rain or damp. Process of Tanning.—l. Lime Treat- ment.—A fresh hide being taken, the inner side is well rubbed in with lime, tightly folded up, the inner side inside, and immersed in water contained in a broad-mouthed earthern pot or ‘“‘nand” for ten to twelve days, the hide being kept pressed down with a heavy weight. During this period it is taken out every third or fourth day, well shaken, and again rubbed in with lime and put back in the ‘‘nand.” About three seers of lime are rubbed into an average sized hide on each occasion. As many as four hides can be treated at the same time in this way. In place of the “‘nand” a pit two feet by two and half feet is some- times dug in the ground for the same purpose. When the above process is complete the hide is taken out, well kneaded with the hands aad the lime washed off with cold water. All shreds of meat that remain attached to the inner side are carefully removed with an instrument know as a ‘‘ rapi,” while the hair remaining attached to the skin is removed by scraping with a blunt iron blade (kulpi) worked with both hands. It is then once more washed with cold water. 2. Dyeing.—The next stepis to give the hide the requisite colour. This is done by the aid of one or two dyeing materials, viz., the young leaves of Anogeissus latifolia (dhaura), of the mature leaves and twigs of Phyllanthus emblica (aonla). The leaves of the ‘‘dhaura” are collected in the month of May when they are young and tender, and after being dried in the sun and pounded are ready for use. The *‘aonla” leaves and shoots, on the other hand, are collected in November and December when they are mature and tough. About four seers of the powdered ‘‘dhaura” or ‘‘aonla” leaves are put into a “‘nand” with cold water and well stirred in this solution, the hide now immersed and left for from 6 to 8 hours. It is then taken out, wrung dry, and again immersed in a fresh solution. This process is continued every two or three days until the hide has assumed the required colour vary- ing froma pale yellow toa light brown. The length of time required to give the requisite colour may be from three to nine days, according to circumstances, Sometimes both ‘dhaura” and ‘aonla” leaf solutions are used alternately. 3. Tanning.—The colour process being completed the hide is ncw ready to be tanned. Theedgesof the hide are brought together and stitched so as to form a sort of bhisti’s “mashak” cap- able of holding liquid, and termed ‘“‘adhurhi.” It is then slung up to a post or tree and filled with water. Into this water is now thrown from 20 to 30 seers of the prepared Kohar bark. An - Dyes and Tans. 14 earthen vessel is placed underneath to catch any liquid that may leak out, which liquid is from time to time poured back into the improvised “‘ mashak,” thus keeping it. continually filled up. The object of this is to subject the entire skin to the action of the tanniag mate- rial held within in solution. The skin remains thus for two days, and on the third day it is inverted and left for another three days in this new position, while still fuli of the solution. In six days the process is complete, the solu- tion is drained off, the stitches holding the sides together are cut away, and the skin now converted into leather; after being dried in the sun it is ready for use. The above is a description of the ordinary process employed. It may, however, be varied by mixing with the Kohar bark ‘‘dhaura” and ‘‘aonla” leaves in the proportion of two of bark to one of leaves. Source of Supply of the Raw Materials’ —Having now described the process of using the bark, I turn to the question of the raw material from the forests or wherever it may be available. The first point to draw attention to is the loca- lity in which the Kohar tree (Terminalia Arjuna) is almost always found. In the C, P., I think, it is safe to say that 95 per cent. of the Kohar trees are to be found growing if not actually on the very bank of perennial streams and annual water- courses with half their root system exposed in the bed of the streams, yet seldom if.ever more than 20 feet from the edges of such streams. This pecu- larity of the tree is very marked. How- ever rich and moist the soil you will not find a Kohar tree, in this part of the country at any rate, far removed from a stream. The result as might be expected is that whether in forest or in open cultivated land, wherever a perennial stream flows or a stream that keeps pools of water in it here and there throughout the hot weather, the greater proportion of trees, say 75 per cent. growing along such streams, are Kohar trees. Itfollows then that all thesupplies of this bark must be obtained from trees erowing along the banks of streams and water-courses. As previously stated, the collectors of the bark are quite indif- ferent to the effect of their actions on the trees themselves, with the inevitable result that considerable numbers of Kohar trees are killed annually to sup- ply the chamars with the bark they require for their tanning process. The death of these trees is further hastened by the period of the year chosen to remove the bark, z.e., from April to June, when the hot scorching winds blowing at the season effectually debar the | JANUARY, 1909, damaged trees from any chance of re- covery. What is therefore happening is that streams and water-courses are rapidly being denuded of the tree growth growing along their banks. Influence of Tree Growth on Conserving Water supply.—Now a great deal has been written lately in the Indian Forester and elsewhere on the subject of the influence of forests on water supply and rainfall, and not without reason. I would specially mention ‘‘ Notes on the Influence of Forest on the Storage and Regulation of the Water Supply ” by Mr. S. Eardley-Wilmot, Inspector- General of Forests. (Forest Bulletin, No.9.) Not the least important point in this intensely interesting question is the influence of the growth in maintainiug an equable flow of water inthe streams and keeping up the ‘‘ spring level” of the water in the subsoil. It is unneces- sary to go into the arguments and reasons in support of these facts, they will be found fully explained in the literature referred to above, but they are incontestible facts. To put it shortly, by preserving the tree growth along the banks of streams you (1) mitigate the violence of the rush of water in the streams during the rainy season, (2) prevent erosion of the banks, (8) maintain a more equable flow of water in the stream, and ~ thereby (4) tend to lengthen out the period of flow, (5) assist in keeping the water in the subsoil at a higher tevel. Conversely by destroying the tree growth along these trees you obtain the very opposite effect. That this effect is baneful in itself goes without saying, but, and I wish to emphasize this point, it is particularly harmful in the region to which I am referring. Liability to Scarcity of Water in Regions where most Damage is done to Kohar trees.—In the Nimar district the rainfall is very scanty averaging about 30 inches, but varying from as little as 18 in. to over 50 in. The district is therefore peculiarly liable to scarcity of water. Now, the tract where most damage is done to the Kohar trees consists of hills of trap with the very poorest soil covering, large stretches of sheet rock being frequent. The tree growth on these hills is of the scantiest, consisting entirely of very open Salai (Boswellia serrata) forest. Along the base of these hills stretches a broad rich ~ valley intersected by streams and water- courses fed by the rain of these hills. It is not so long ago that most of this valley was under forest. Now, it is all given up to cotton cultivation, and practically Rah JANUARY, 1909. ] the only trees left in it are such as have survived along the banks of the streams. Here the destruction of Kohar trees is going on apace. From the nature of the soil covering and tree growth on these hills it is clear that during the monsoon the proportion of rain running off and not absorbed, will be much greater than from more favourably con- stituted forests as regards soil covering and tree growth, while the rush of water in the streams at any particular moment of heavy rainfall will also be greater. Under these circumstances the value of the existing tree growth along the streams in the valley is considerably enhanced, and it behoves us’'to maintain at all costs the maximum of such tree growth. Quantity of Bark used annually in Nimar.—It is estimated that about 4,250 mds. of Kohar bark are annually usedinthe Nimar district for tanning purposes, An actual experiment made to ascer- tain the quantity of bark obtained from a mature and average sized Kohar tree showed the green weight of the bark removed to be 47 seers. The weight of this after drying was 21 seers. A reference to the ‘‘ Process of Tanning” will show, then, that the bark of one tree is not quite sufficient to tan one average-sized hide. Taking halfamaund (20 seers) as the average quantity of dry bark obtained from one tree, and the total quantity of dry bark used in the district in one year as 4,250 maunds, we arrive at the con- clusion that no less than 8,500 Kohar trees are annually stripped of their bark, and, as all this bark comes from Malguzari and Ryotwari areas, the damage done must be very extensive even after making allowance for such trees as recover from the treatment they are subjected to. Necessity for Kestricting the Removal of Kohar Bark.—Hither then the absolute prohibition of the barking of Kohar trees should be enforced or ‘steps taken to reduce the damage done to the trees toa minimum, In Government forests extraction of the bark is entirely for- bidden, but it is chiefly in the Malguzari and Ryotwari areas that the mischief is greatest. Undec the rulesapplicable to waste areas in Malguzari villages, the felling of any tree growth within 20 yards of a stream in which water ordinarily remains till the month of January is prohibited. There is nothing, however, in the rules forbidding the barking of trees with its inevitable result the speedy death of the tree. Dyes and Tans. Orders have lately been issued by the Deputy Commissioner enjoining on all Malguzars the importance of maintain- ing, as far as possible, a permanent tree growth along streams and pointing out the damage done by the barking of Kohar trees, and recommending that at least one-third of the bark on any Kohar tree should be lett when barking the trees. It is questionable, however, whether the recommendation will be acted up to. It, would therefore be preferabie to absolutely forbid the removal of Kohar bark, and the chief point in favour of this prohibition is that the use of Kohar bark is not absolutely indispensable to the preparation of leather. Substitutes for Kohar Bark.—From enquiries made it has been ascertained that the tanning process can be carried out with the use of ‘‘dhaura” and ‘““aonla” leaves only, and in certain parts of the district Kohar bark is sel- dom, if ever, used. It is said that Kohar bark used by itself produces a hard leather, and that therefore leaves of “dhaura” and ‘‘aonla” are mixed with it. The bark of Saj (Ternunalia tomen- tosa) is sometimes used in place of Kohar bark, but there are difficulties in its, removal from the treeand hence it is not much in favour. The fruit of Ghatbor (Zizyphus Xylopyrus) is also frequently made use of. It would appear that the use of Kohar bark is more a matter of habit than necessity. The chamars of Burhanpur tried very hard to get a reversal of the decision that no bark was to be extracted from Government forests, stating that their industry de- pended on the supply of this bark. Just about this time I had come across a number of bushes of Awli (Cassia auriculala), growing on waste land round the town. This species, as is well known, provides one of the best tanning materials and is largely used in the Madras Presidency, yet when asked aboutit the chamars of Burhanpur stated that they had never used it and did not even know of its value as a tanning agent. Cassia auriculata will grow equally well on dry stony soil and on _ black cotton soil, and there seems no adequate reason why it should not be grown in sufficient quantities to supply the chamars of Burhanpur with all the tanning material they require. There are several waste patches within the municipal limits which are eminently suitable for the growth C. auriculata, and, which, if planted, or sown up and properly managed, would in a very short time become a valuable source - a iy Dyes and Tans. 16 [JANUARY, 1909. | of revenue to the Municipality, besides supplying a cheap and excellent tanning material at the very doorsof the chamars who require it. The first crop of bark is obtainable when the shrub is five years old, so that: the initial cost of cultiva- tion is by no means prohibitive. Then, again, there is Acacia arabica (Babul) the bark of which furnishes an excellent tanning material. The Babul grows particularly well on black cotton soil, and as the valley at the entrance of which Burhanpur is situated, consists almost entirely of this soil, there would be no difficulty in growing this species. Tenants and ryots might be induced to plant their field bound- aries and hedges with Babul, and would always be sure of finding a market for the bark. Cost of the Bark.—The chamars, as a rule, extract their own bark obtaining licenses from the Malguzars at the rate of Rs.3 to 4 per ecart-load of dried bark. This means an average royalty of 8 annas per maund. Reasons for the Use of Kohar Bark.— The real explanation of the use of Kohar bark is that it is easy of extraction ‘and has been obtainable in abundance, and the idea of any restrictions ona custom of long standing is of course repugnant to the ideas of any native. —Indian Forester, October, 1908, Vol. XXXIV.

INDIAN WATTLE BARK. ‘“Wattle Bark” is the general name applied, both in commerce and the arts, to the barks of the various species of Acacia exploited within the tropics and elsewhere for the tannin which they contain. Over thearid sandy wastes that occur throughout the torrid regions of the globe, the thorny acacias instal them- selves on the banks and beds of rivers and streams and shallow depressions such as admit of the temporary lodge- ment of water during rain. In some situations during seasons of flood, they are frequently completely submerged for days, but recovering themselves from the depressing effects of the transitory deluge with seeming impunity, they flourish through the drier months of the year under conditions of climate untenable to all but very few species of broad-leaved trees. Indeed the rigors of climate to which the zones that constitute the habitat of the acacias are subjected, may be gauged from the fact that some of the species are unable to develop ordinary leaves. The phyllodes, which take the place of the latter, are suitable modifi- cations of the stem equipped to perform all the functions of the leaves they substitute. Although the foliar organs of most of the acacias are usually small and seemingly delicate, the profusion in which they ‘occur in the plant, their remarkable phyllotaxis or arrangement, and their incessant and vigorous activity throughout long and arduous periods of vegetation result in the formation, among the rest, of comparatively dense cortical layers surcharged with a variety of valuable substances of which the most important is tannin. When it is re- membered that the tropical acacias form a large and well distributed group of plants, it will be realized that the availability of tannin from this source alone is great indeed. Nevertheless, it is a notorious fact that only a few ‘species of the genus are exploited for the extraction of tannin. In India, again, with about eighteen species that are indigenous to the warmer parts of the country, (Willd., and Acacia catechu, Willd.,) are the only ones at present employed to any extent in the art of the tanner.. More- over, it must be further conceded that, so far from making the least attempt to commercially exploit the bark of th, indigenous acacias. we have permitteq ourselves, at considerable expense, t introduce four, and experiment with two of the so-called wattle bark trees of’ Australia. Introduced on the Nilgiri hills of Southern India in the early forties of the last century, these in- teresting and valuable exotic acacias required no less than a period of thirty long years to become acclimatized and completely naturalized. And even though as doubtless they do, the black and silver wattles of Australia (Acacia decurrens, Willd., and Acacia dealbata, Link.) yield relatively large quantities of tannin of a quality which is inferior to none, not only in India but wherever else the factors of soil and climate have been found to adequately suit their several requirements, their adaptability and general alone are circumstances which are un- worthy to be advanced against the serious consideration of the neglect to which the local species have been now and always consigned. : Is ; re haa the barks of Acacia arabica, . excellence in themselves. JANUARY, 1909.] In endeavouring to invite public at- tention to the immense possibilities that lie in the direction of the systematic exploitation of some of the commoner Indian acacias as sources of tannin, it must be mentioned that the mocerate- sized, diffuse-branching, gregarious species, botanically known as the Acacia arabica, is certainly one of the most neglected but valuable. Although the quality of the bark of this acacia is inferior to that of the Australian wattle and even to that of the Acacia catechu, the extent of distribution of the species in India and the numbers in which they occur there are such as to warrant the eonelusion that its systematic exploit- ation for tannin-extraction is likely to meet with favourable results by retriev- ing in quantity whatit cannot in quality. The natural regeneration of the tree being easy but somewhat slow from seed, its artificial reproduction, for ecouomic purposes, could be more successfully accomplished by the creation and development of shoots and suckers from the stool. For this the tree requires to be coppiced at suitable intervals, from time to time. The safest period, con- sistent with utility, of the economic exploitability of the species, is said, on good authority, to be ten years,— the age at which the. bark has been found to be mature enough to contain tannin of sound and serviceable quality. At this age, too, the possibility is greater than at any other recently anterior one of obtaining an appreciable quantity (half a ton) of bark from each tree, that will have been coppiced. With the yield of tannin at 15 per cent. ‘actual experiment giving 18°95) a tree would produce 168 pounds of the sub- stance at the close of the tenth year of its age. Thereafter, the yield, which improves with coppicing, would directly depend on the number, size, and vigour of the shoots which would be permitted to develop on the stool from those given out after each periodic felling, As regards the other Indian acacias, in- formation of a reliable nature relating to the yield of tannin from the bark is at present unavailable. The important Khair (Acacia catechu) itself is seldom looked upon as a source of tannin, outside the great and well known capacity of its wood as a yielder of catechu or catechu-tannin (catechin), No endeavour, beyond the local and, therefore, comparatively limited appli- cation of its bark as a tanning material, — has as yet been made in India. To obtain the catechu the tree is felled and its heartwood cut up into chips and boiled. The bark, however, with its stores of tannin, is usually left to rot on 3 17 Dyes and Tans the ground. Some idea of the extent to which this wastage of a useful and valuable raw material now takes place in the country may be gained from the fact that throughout the wide area of its distribution thousands of trees are annually felled. Why, when the wood is being boiled for catechu, or otherwise utilized throughout the country, the bark is not at the same time treated for the manufacture of an extract which assuredly contains a high percentage of tannin of good quality is a question which so far appears to have been pro- vocative of no reasonable or satisfactory response. The fact, at any rate, seems to savour of some of that sublimely supine indifference which the son of the soil has been proverbial for displaying in treatment of great and glorious heritage—a mine of wealth whose super- ficial veins themselves still largely wait upon his consideration. Besides the two indigenous acacias deseribed above as sources of tannin, the undermentioned Indian species, too, deserve our best attention in India :— (1) Acacia Farnesiana, Willd.—A low erect shrub or small tree occurring throughout the plains of India and Burma; it has bright yellow flowers that are fragrant and arranged in the axils of the leaves; it isarmed with long straight spines. (2) Acacia ferruginea, D. C.—A large deciduous tree with reddish brown bark; armed with short, hooked, double spines, the flowers occurring in axillary peduncled spikes. (8) Acacia jacquemontu, Benth.--A small elegant bushy shrub with smooth stem and straight, slender, shining spines; flowers like those of (1). (4) Acacia Latronum, Willd.—A small tree or shrub of Southern India, occur- ring in gregarious thickets; its flowers are given out in numerous spikes from the nodes of the branchlets when the tree is leafless and double spines are long and straight. (5) Acacia planifrons, W. and A.—A species similar to (4) in habit and dis- tribtuion but with grey lenticels in place of spines. (4)and (5) form fiattened tops that are very conspicuous and remarkably typical of the dry open forests in which they occur. (6) Acacia leuwcophica, Willd.—A large deciduous tree with short, straight, white spines, flowers in small heads borne on long terminal tomentose ‘panicles. (7) Aeacia modesta, Wall.—A small tree with short, hooked, double spines and small sparse, greenish yellow spikes of fiowers. “Dyes and Tans. (8) Acacia Suma, Kurz.—A moderate- sized tree with glabrous. bark and tomentose branchlets, hooked double spines, and yellowish white flowers. (9) Acacia Sundra, D.C.—A large tree [JANUARY, 1909 resembling Acacia catechu, but with dark brown branches and no pubescense. —A. M. S. in Capital.—Indian Agri- culturist, August 1, 1908. FIBRES. THE INDIAN COTTON CROP. The following first general Memoran- dum on the Cotton Crop of the season 1908-09 has been issued by the Commer- cial Intelligence Department, India. The provinces dealt with in this memo- randum represent, on the average of the five years ending 1906-07 a total of 15,007,700 acres under cotton, this being equal to 76 per cent. of the entire reported cotton area of India. The memorandum relates, however, mainly to the early crop and records acreage only. The total area at present reported is 11,118,000 acres against 11,255,000 acres (revised figures) at the same date last year. There is, therefore, a net decline of 1°38 per cent, Noattemptis madeat this season to estimate the probable outturn; but. the present condition of the crop is reported to be generally good or fair, except in parts of Bombay and Burma.

EGYPTIAN COTTON IN SIND. The area in Sind under Egyptian cotton is about 3,700 acresin Thar and Parkar district.—Indian Agriculturist, Vol. XXXIII., No. 9, JANUARY, 1909.} DRUGS. QUININE IN INDIA. Quinine has become in the Indian mind the type and chief of Western drugs, says the Resolution upon the triennial report on the working of chari- table dispensaries in the Punjab. Mala- ria here as elsewhere is the chief scourge, and, with the habitual resort to quinine, the Indian has come to feel that it is on this that hospital treatment must rely. The result is that when the supply of quinine proves inadequate, as is often the case, there is disappoint- ment, as though no other treatment could be effectual, and doubtless the growing confidence in hospital treat- ment receives some check. One remark- able feature of outdoor medical relief is disclosed in the report, that is the num- ber of patients who did not see the doctor themselves but were represented by friends. This system so far from waning seems to grow, for in this case no fewer than 230,475 sufferers underwent ‘‘absent treatment.” The proportion of those so dealt with varies so greatly in different districts as to suggest that tactful methods might effect some im- provements.—Indian Agriculturist, Vol. XXXITII., No, 9. 20 [JANUARY, 1909. EDIBLE PRODUCTS. POTENTIALITIES OF PLANTAIN MEAL. One of the greatest drawbacks to the economic development of India is that most of her potential industries are permitted to lie dormant till such time as foreign capital may happen to be introduced to work them. It is not because there is not sufficient capital in the country, but because the owners prefer to hoard or invest it in securities that cannot yield anything like the return a well-managed industry would be likely to do. To some extent this lack of enterprise is due to ignorance as to what industries hitherto unex- ploited would be likely to turn out profitable, but it is more frequently attributable to lack of initiative and disinclination to assume the role of the pioneer. From time to time we have drawn attention to what we believe to be suitable openings for Indian trade; and, amongst other minor industries, to the manufacture of banana or plan- tain meal. The flour of the plantain, under the name of “Bananine” and ‘‘Banaharina” has been manufactured for several years in Central America and the West Indies, It is produced from partly ripe fruit by removing the skins, drying the edible portion and reducing it to powder ina grinding machine. The average weight of fruit required to produce 1 ewt. of flour is 5 cwt., that is a yield of 20 per cent. In the Indian Trade Journal of January 17th we mentioned that a company had been started in London to manufacture banana flour for bread, banana oats for porridge, banana custard powder, banana cocoa, banana cake and pastry flour, banana blane mange powder, banana jelly powder, banana health salts, ete., and it may have struck readers as curious that capital should be forthcoming for such a purpose in a country where the fruit does not grow, while in India, where the cultiva- tion of the plantain is universal, enter- prise of this kind on any considerable scale is practically non-existent. There may or may not be good reason for this; but the fact remains that for years past the health-giving and sustain- ing properties of banana meal have been known not only in civilized coun- tries, but also amongst the natives of South Africa, and presumably there is room for it in the list of the world’s edible products. The late Sir H. M. Stanley, during his equatorial travels, was so struck with the value of this product, that he expressed the opinion that, if only its virtues were publicly known, it would be largely consumed in Kurope, especially by children and persons of delicate digestion. There are a few scattered concerns in India, eg., at Saharanpur, where plantain meal is manufactured in a small way, but practically nothing seems to have been done to produce it ona large scale, and with such machinery as will turn it out in commercial quantities at the lowest possible cost. A European firm at Calicut, which has lately been examining the possibilities of this industry, has favoured us with asample of banana meal prepared by it. This sample Mr. Hooper, of the Indian Museum, has very kindly analysed for us with the following result :— Moisture ...

It is quite free from tannin, which is found in some samples as banana flour, and should be very digestible. Its composition is similar to that of the flour made from bananas in America, as the analyses of samples from Jamaica and Venezuela will show :— Jamaica.

Banana meal as an article of food, according to its analysis, occupies an intermediate position between the cereal flowers and arrowroot starches which should recom- mend it especially for infants and jnvalids.” In Venezuela, we believe, the retail price is about 5as. for 1 lb. packages, but in Caleutta the retail price for the same weight of plantain flour is rather high, viz., Re.1; but if more attention JANUARY, 1909.] were given to its manufacture, no doubt it could be produced locally at a more reasonable cost. It is believed that Rs. 360 per ton represents the average cost of production in Saharanpur, in Bengal, and Anuradhapura in Ceylon; and for foreignmarkets the cost of pack- ing, freight and shipping charges have to be addedtothis figure, say another Rs. 20 per ton. The total cost should not ex- ceed Rs. 380 per ton orjust under 3 as. per lb., while the retail price in Caleutta works out at Rs. 2,240 per ton, leaving a margin of profit of Rs. 1,860 per ton or nearly 500 per cent. The wholesale price in Calcutta is not ascertainable, but even if itis as low as Rs. 600it would leave a handsome margin of profit. In small markets, of course, an insignificant increase of supplies has avery adverse effect on prices, and it has been pointed outtous that banana flour has been placed on the London market at £20 or Rs, 300 per ton (which is less than the cost of production in India), and even then it was doubted whether this price could be maintained in the face of a laige consignment. This is discouraging for manutacturers in India, for they must look for profit in the beginning to their export trade, at any rate until an indigenous demand has been created. Plantain flour, of course, cannnot hope tocompete with farinaceous materials selling in London at £6—£12 per ton, but that is no reason why it should not come to be recognised and appreciated as a dietetic luxury ; and if so, its price should be regulated not by that of wheat and rice flour and potato meal of a low nutrient value, but by that of superior products which command a more restricted but yetanample market. Upon this factor the establishment of the plantain meal industry in India on a scale commercially profitable would seem to depend. FRENCH EXPERIMENTS, It has been found from a series of experiments in French Guinea that an efficient and cheap way of manufac- turing plantain meal is simply to peal the bananas and dry themin the sun. The meal thus obtained is of excellent commercial quality. It is obvious, however, that this procedure can only be followed in tropical countries, so that an apparatus which permits of desicca- tion at any time is often necessary when business is to be conducted on a large scale. The principle on which these desiccators are constructed is very simple. Allthatis required is to circu- late hot air over the fruit to be dried. The apparatus consists of a furnace, in which any kind of fuel may be used, and a box arrangement in which are super- Hdible Products. imposed a number of trays of metallic net work through which the hot air from the furnace, freed from the gases of combusition, passes and dries the fruit. The trays containing the fresh plantains are placed in at the top of the apparatus and taken out at the bottom. he prices of such desiccators vary roughly from Rs. 800 to Rs. 750. Illus- trations of two such machines may be seen at this office. Further experiments carried out in French Guinea go to show that a hun- dred kilo (kilo, 2,204 lbs.) of bananas in bunches as plucked yield 65 kilos of peeled bananas, and these 62 kilos, treated in the machines mentioned, give about 19°5 kilos of plantain meal, Much, however, depends upon the method of desiccation. When the process is pro- longed in order to obtain a golden colour for commercial purposes the yield may be aslowas 14°32 kilos; and dried too fast not only is the weight seriously reduced, but the fruit becomes carmel- ised and depreciated in value. It will be seen that the yield of plantain flour under ordinary conditions, is roughly 20 per cent., which agrees with Mr. Hooper’s estimate published in our issue of July 16, p. 62, that the average weight of fruit required to produce 1 ewt. of flour is 5 cwt. It has also been ascertained in the course of the French experiments that although unripe and partially ripe bananas may be converted more quickly into meal, ripe bananas which contain more sugar give the best results. In a previous article on the subject we stated that the manufacture of plan- tain meal was being taken in hand by a firm on the Malabar Coast; and we may now add that the climate of French Guinea, where these plantain meal experiments were carried out, is not unlike that prevailing in Malabar, As in Malabar the year in Lower and Middle Guinea is divided into two well- defined seasons—six months of rain and six months of dry weather. The rain commences in the middle of May and end in November. During the rainy period the drying of the fruit is restricted by atmospheric humidity, and it is here that the artificial dryers we have referred to come into use. The average annual rainfall is abont 100 inches.—Indian Trade Journal. PLANTAIN MEAL. Some interesting experiments have recently been conducted in FKrench Guinea in the manufacture of plantain meal of which profitable notice might be taken in this country. It has been Edible Products. 22 found that the most cheap and efficient plan, in tropical countries at any rate, is simply to peel the plantains or bananas and dry them in the sun, the meal thus obtained being of excellent commercial quality. It has been found, further, that a hundred kilos (a kilo equals 2,204, lb.) cf bananas in bunches as_ plucked ought to yield 65 kilos of peeled bananas, and that these 65 kilos should give about 19°5 kilos of plantain meal. The yield of plantain flour, under ordinary conditions, is thus roughly about 20 per cent. which agrees with the estimate arrived at recently by Mr. Hooper, of the Indian Museum, that the average weight of fruit required to producea hundredweight of flour is five hundred- weights. The manufacture of plantain meal has recently been taken in hand on the Malabar Coast, the climate of which closely resembies that of French Guinea, where the experiments referred to were carried out. The most interest- ing feature of the experiments, therefore, for indian manufacturers is that in connection with the artificial dryers, which it is essential to use in the rainy season. Those cost only from Rs. 300 to Rs. 750, and illustrations of them are to be seen at the office of the Indian Trade Journal.—indian Agriculturist, Vol. XXXIII., No. 9. THE CULTIVATION OF GROUND-NUTS. Grounpb-Nuts AS A DRy LAND CROP. The spread of ground-nut cultivation has been steadily advancing during the last two years in all parts of the Presidency. In many districts this is quite a new crop, but it has been found so profitable, that, wherever it has been tried, and the local conditions have been found suitable, its cultivation has rapidly extended, Asconstant enquiries are being received asking for informa- tion regarding the cultivation of ground- nuts, the following general instructions have been written :— 2. Climate and Rainfall.—The ‘‘Mauri- tius” variety of ground-nuts, which is the one now cultivated, takes from 5 to 6 months to come to maturity. During the first two or three months of the crop’s growth, very little moisture is required; the plant can withstand con- siderable QGrought until it starts to flower and forms its nuts. Therefore sowing should be so arranged that the crop will receive the benefit of good rains during the last two to three months of its growth. Some districts get light rains during the south-west monsoon, but expect their season rain [JANUARY, 1909. in October-December during the north- east monsoon. Here sowing should be done in the end of July or beginning of August. In other districts showers are experienced in April and May, while the season's rain occurs with the south- west monsoon from June to September. Here sowing should be done as soon as a sowing rain falls in Aprilor May. Itis evident, therefore, that the farmer must decide for himself whether the rainfall is suitable, and, if so, what is the best time for sowing. 3. Soil.—Ground-nuts should not be grown on a heavy stiff soil for two reasons. Firstly, though the plants appear to be growing well, the yield of nuts is small. Secondly, the difficulty and cost of harvesting the erop is too great to render the crop as profitable as other crops, which can be grown on such land. Sandy or loamy soils are perhaps best suited to this crop, and it is essential that the land should be well drained as the ground-nut does not like a soil where water can stand. In fact, when quite young, evena very heavy rainfall will often injure the crop and check its growth. 4, Preparatory Cultivation.—It is most essential that the land should be properly cleaned and treed from weeds before this crop is planted; because, during the last two months of the cron’s growth it is impossible to doany weed- ing, and this, being the time when the season’s rain falls, is naturally also the time when weeds get ahold on to the land and thereby diminish the yield. Korai and Hariali are probably the two weeds which most affect the yield of the crop, and every effort should be made to destroy these by cultivation, when the land is fallow, %.e., during the dry season. If theland is clean, probably three ploughings and cross-ploughings will suffice. rad 5. Manuring.—This should be done before the last ploughing and : cross- ploughing. If cattle manure or village sweepings are used, this should be spread evenly on the field, and not left in heaps to dry up with the sun. All large lumps of manure should be broken up so as to distribute the manure as evenly as possible, and as soon as itis properly spread, it should be ploughed in. It will always pay the cultivator to mauure his land for this crop. Cattle manure. village sweepings and ashes are always of value and can be applied at the rate of 15-20 cart-loads per acre. 6. Seed.—_When purchasing _ seed, always buy the nutsin theshell, Ground- nuts for seed should always be saved from the previous season’s crop. The JANUARY, 1909.] nuts should be shelled by hand, and only good, sound, well-filled kernels should be used for sowing, All mouldy kernels should be rejected. 7. Sowing asa Pure Crop.—The usual method of sowing consists of dropping the seed inthe plovgh furrow behind each plough. This is not only very wasteful of seed, but the plants are much too close together to develop properly, and it is impossible to do any after- cultivation except with the hand hoe, which is always expensive, while if exceptionally heavy rains are experienc- ed. the crop is often liable to become waterlogged. A better method of sowing is to drop the seed at intervals of 6-9 inches according to the quality of the soil in every third plough furrow. In this way, only 10-12 Madras measures of kernels instead of 383 Madras measures are required to sow anacre, Hach plant has ample room to develop, and if care is taken to continue the furrows up to the edge of the field, after-cultivation ean for the first three months be done with the bullock-hoe or Danthelu. The inter-cultivation slightly raises the land along the rows into the wide low ridges, and this, besides keeping the soil mellow, considerably improves the drainage. 8. Sowing as a Mixed Crop.—As ground-nutstakefivemonths togrow, itis the practice in the South Arcot District to take a catch crop of some cereal, such as cumbu or cholam, off the land at the same time, | For this purpose a3-4 month variety of such is usually chosen, so that the cereal crop can be reaped while the ground-nuts. which are dribbled in, after the cereal has sufficiently grown to shade the ground are still small. The method usually adopted is to sow the cereal broadeast, covering the seed with a light plough, after which the ground is levell- ed and the seed-bed is made firm by dragging a harrow made of thorn branches across the ploughing; when the cereal crop is6 inches or so high, opportunity is taken after a rain to weed, hoe and thin the crop. A second hoeing and even sometimes athird is given if rain occurs and cakes the _ surface. When the cereal is about to flower, the seed of the ground-nut is dibbled in by hand at intervals of about 9 inches apart. This careful method of cultiva- tion greatly benefits the cereal crop, and prepares the land for the subsequent crop of ground-nuts. Tenaior Ragi is often grown asa cereal on land com- manded by a well, instead of the ordinary dryland cholam or cumbu. 9. Inthe case of Ragi, the crop is trans- planted after the land has been laid out into square beds and irrigated, aud the 93 Edible Products. ground-nut is dibbled in later as des- cribed above at intervals of about 6 inches. The Tenai is sown broadcast as in the case of cumbu and cholam, and after sowing, the land is laid out in beds for irrigation, if thisis found to be neces- sary. As the straw of this crop is brittle, and as it matures early, the ground-nut is naturally sown after the Tenai has been harvested either by hand or behind the plough. 10. If ground-nut is to be grownin a district where the drill and the other implements for cultivation are used, the same system of taking a catch crop cereal could be adopted. The cereal could be sown in 18 inch drills and the ground hoed between the rows with the Danthelu or bullock hoe. At the right time the ground-nut could be dropped behind the plough in a furrow made midway between two rows of the cereal. After the cereal is reaped, inter-cultiva- tion can still be continued between the rowsof ground-nut. This method of cultivating a cereal ground-nut crop has been tried with success at the Palur Agricultural Station. 11. After-cultivation.—The usual method of cultivation is to loosen the soil between the plants with the hand hoe. This means that coolie labour must always be available, or that the crop must suffer from want of cultiva- tion. Thescarcity of labour is one of the serious drawbacks to the present system of cultivating ground-nuts, and will always be so, especially in dry red soil tracts which cannot support a large population. Hence the .aethod of sow- ing the crop in rows and doing the inter- cultivation with the bullock hoe is strongly urged. Frequent hoeings, whether by hand or by the bullock hoe, are often necessary. No definite number of times for doing this can be given, as so much depends on the season, but it is safe to say that for the first three months hoeing should always be done as soon as the land is dry ‘enough after a good rain. This helps to keep the moisture in the ground, it enables the forming nuts to penetrate into the soil and it keeps down weeds. 12. Harvesting.—The crop should be ready to harvest at the end of five months. The exact time must, however, be learnt by the cultivator himself. When the stalks to the underground pods have dried and the skin on the kernels has turned pink, the crop can be considered ready for lifting, but there will always be a few pods near the ends of the branches which are still quite young, when the bulk of the crop is ripe. The method of harvesting also varies Edible Products. with the local conditions of soil and cli- mate. Onvery loosesandy soil it will be found that by loosening the soil under each plant practically all the nuts will remain adhering to the branches from which they cau be picked, Often in South Arcot, on such light soil a mam- mootie is attached to a draught pole and worked like a plough through the crop to loosen the soil at a depth of about four inches. If the crop has become too ripe, or if the soil has baked hard, many of the nuts will be left in the soil; in this case it would be better to remove all the tops first, pick any nuts which adhere to them, then loosen the soil with a mammotie to a depth of 4 inches, and have the crop collected by women, who carefully go through all the soil and pick out the nuts. When the nuts have all been collected they should be thoroughly dvied before storing, by spreading out in the sun. In the evening they are heaped up and covered with straw, and again spread out the following morning. This con- Pee until the ground-nuts are quite ry. 18. VYield.—This naturally varies with the treatment. With good cultivation, sufficient manuring anda normal season, a vain-fed crop can be expected to pro- duce a crop of 700-1,200 Madras mea- sures. Many people who try this crop are at first encouraged by the large yields obtained from poor soil without any manure being applied, and are afterwards disappointed when the same treatment in the following season does not produce such heavy yields. As previously mentioned, it will always pay the farmer to manure his land for this crop. 14. The Disposal of the Crop.—The ground-nuts themselves, as arule. find a ready sale, though sometimes in a new district, where the cropis unknown, there is difficulty. In such cases, the ground-nut oil is usually saleable, and the kernels can be crushed as any other oil seed in the ordinary country oil-mill. One hundred pounds of ground-nut kernels will produce from 36-40 pounds of oil. The cake which is obtained can be used either as cattle food, or it can be applied directly asa manure. In the South Arcot district many of the culti- vators apply ground-nut cake at the rate of one candy per acre to the wet lands for paddy, so that their village manure will be available for the culti- vation of the ground-nut crop; Experi- ments have been started at the Palur Agricultural Station to find out whether ground-nut cake will not be equally pro- fitable, when applied as manure to the ground-nut crop. Ground-nut straw, [JANUARY, 1909. when dried, makes excellent fodder for cattle, and should be mixed with the straw of cereals for feeding. ; IRRIGATED GROUND-NUTs. 15. Ground-nut, as a dry irrigated crop, is now. extensively grown in the South Arcot District duving the hot weather months, and the rapid exten- sion of this cultivation shows how pro- fitable it must be from a monetary point of view. There seems to be no reason why this method of cultivation should not be extended to other dis- tricts, where the soil and water-supply are suitable even if the ground-nut, as a rain-fed crop, cannot be grown. _ 16. Thesystem of cultivation of the irrigated ground-nut crop in South Arcot is merely an adaptation of that adopted for the rain-fed crop, and as the expected yield ‘is greater the land is more heavily manured. The crop is usually grown mixed with ragi, the land being laid out into small square beds after sowing ragi broadcast, and the ground-nut dibbled in afterwards as described above. Occasionally, if the land cannot be prepared at the right season, ragi seedlings are raised in a nursery and afterwards transplanted. Sometimes the ground-nut is grown as a pure crop, the seed being dibbled in 6-9 inches apart in the dry beds before irrigation, and watered immediately after the sowing is completed. Too close sowing is the principal objection to this method. The cultivator still con- tinues to plant the ‘‘Mauritius” nut at the same distance that formerly he planted the ‘‘country” ground-nuts, and seems not to have realised that, whereas the “country” ground-nut formed-its pods near the crown of the plant, and could therefore stand to some extent this close planting, the ‘“*Mauritius” variety forms its nuts all along the main branches. Thus by plant- ing closely the Mauritius nut with its flat spreading habit soon covers the ground and the branches are thus forced to grow up into the air. With this close planting, proper weeding and hoe- ing soon become impossible, besides having all to be done by hand. In consequence, the soil becomes hard and caked, while weeds which have only been checked while the crop is young soon spring up when weeding has to © stop. This close planting also means a great waste of water. The whole surface of the ground has to be flooded, and unless the land is hoed by hand (an operation which is both expensive, if done thoroughly, and often requires more labour than is available), the water soon evaporates from the surface of the ground, thereby entailing much more frequent waterings. JANUARY, 1909.) 17. Cultivation and Sowing.—The method of cultivation adopted on the Palur Agricultural Station is still under trial, but there is every reason to believe that equally good, if not better, crops can be obtained at great saving of seed, water, irrigation, and hand cultivation. As recommended in the case of the rain- fed ground-nut crop, the seed is sown in every third plough furrow, the kernels being dropped at intervals of 6-9 inches in the furrow. Before sowing, the land is irrigated, and as soon as it is dry enough the surface is levelled with a harrow. The moisture in the soil is sufficient to germinate the seed, and when the crop is once up the rows can plainly be seen. 18. After Cultivation and Irrigation. —Furrows for irrigation are opened with the country plough between the ground- nut rows, and water is allowed to run down these and thus irrigate the crop without flooding the whole surface of the land. Occasionally, if the land is not level, subsidiary channels have to be made across the rows from which the crop can be irrigated in each direction along the furrows. After each irrigation, as soon as the soil in the furrows is dry enough, the surface soil in the furrow is worked with a bullock hoe. This prevents the rapid evapor- ation of water from the surface, The next irrigation is not given until it is seen that the crop actually requires it, In this way for the first two-three months, irrigation should not be neces- sary more often than once a fortnight, and often the intervals between irriga- tions are considerably greater. The time between the irrigations must, how- ever, be left moro or less to the discretion of the cultivator, as this depends toa great extent on the texture of the soil. As long as the plants look vigorous and healthy in the early morning before the sun is hot, irrigation is unnecessary. Whenthecrop nearly covers the ground, it is not possible to continue working between the rows with the bullock hoe, and the furrows must then be left open after the last irrigation, sothat watering can be continued without disturbing the crop. During the last two months it will be found that more frequent irrigations are necessary. The plants are now forming their nuts and require a greater quantity of water. At the end of five months from the time of sowing it will be found that the majority of the nuts are fully formed, Irriga- tion must then cease in order to ripen off the crop, The harvesting is similar to that described above for the dry crop, except that the land must once more be irrigated to lossen the soil sufficiently 4 5) Edible Products. to lift the crop, The yield of the irri- gated crop will vary from _ 1,000-2,000 Madras measures, and even yields of 3,000 Madras measures are common, — Bulletin of the Department of Agr- culture, Madras, 1908. TAMARIND CULTURE. From time immemorial the tamarind ranks among the useful trees of India. There is scarcely any family of trees that are more generally useful in tro- pical climates than the tamarind tribe. The Arabs first learnt its essential properties from the Hindus, and thence it gradually made its way into Europe. It was at one time known as the Indian date among the ancient Arabs and the Persians. In EKurspe it became known as Tamarindus Indicus. It grows every- where in India with a little care. In preparing plantations the rainy season is the best one. The seeds should be strewn on damp soil, and after a lapse of two or three years the tree grows big enough. In the forests and hilly regions these trees abound in great many num- bers. The tree grows big within a few years and lives for a considerable length of time. The height of it varies from 75 to 80 feet. The outspreading branches of these give a beautiful aspect. The circumference of the trunk is 24 feet. The trees flower in the spring and fruits ripen in winter. From five to six maunds of fruits can be gathered from a full-grown tree. The tamarind fruits are used in preparing condiments and are exported in large quantities to foreign countries. The tamarind is the bare necessity of life with every Indian villager. He may live without mangoes or jack fruits, but this he cannot dis- pense with. From the green leaves to the outer husks are used as eatables by the Indian villager. There is a story current in Bengal about the usefulness of the tamarind. There lived at one time a logician in Nadia. He had one day no other articles of food except some rice in his house. When inter- rogated by his wife as to what she should prepare for curry, the logician got up in haste and directed his eyes towards the tamarind tree. His wife took itin her head and forthwith came out of the house to pluck some tamarind leaves wherewith to prepare a nice curry, When the logician returned home and sat down to dinner, her lov- ing consort got a dish of tamarind curry which he partook of with great relish. The logician, after eating to his heart’s content, remarked: ‘Ours shall be no want so long as this nectar-giving Edible Products. 26 tamarind tree is in our house.” Though this ig current as astory in Bengal, to bring home to the mind of our men the usefulness of the tamarind, yet we can, by no means, overlook the importance underlying the properties of this tree. It has a good deal of medicinal properties conducive to human health. The green tamarind when eaten aids in the secretion of bile and is an antidote to rheumatism. The viscid substance of the ripe tamarind: when pasted over a boil helps to bring it to head soon. If applied at the top of a betel rind and placed a suppositoria on the anus of a child it will have the effect of loosen- ing its bowels.. The tamarind is required for preparing confectionaries and tartaric acid. A kind of medicated salt is pre- pared out of its husks burnt into ashes. The leaves, when applied, after it has been pestled over some parts of the body afflicted with pain, produce a kind of soothing sensation ; the salt prepared out of its ashes is a good medicine for dyspepsia. Place some leaves in hot water, and when they are well boiled put them on a cloth coloured in blue, and it will give a crimson hue. The silversmiths in the Deccan use a kind of acid pre- pared from the tamarind to brighten the gloss of silver. The stone of the fruit is generally thrown away as useless things by our men. Our countrymen do not know its proper use, Mr. David Hooper writes in the Agricultural Ledger, 1907, about the use of its stone. He says: ‘“ During the time of famine the poor people eat the tamarind stones.” The tamarind trees are mostly to be seen in Madras and Central India. The stones of the tamarind are first soaked in water for about half an bour and then boiled for eating. Some fry them first and then boil. When they are well boiled, take off the outer covering and the kernel will give a good relish when eaten. The kernel is sometimes dried in the sun_ or fried and then pulverised into fine flour. Cakes or bread can be prepared from this flour. Reports hi current with mental effects eaten. Cases have at some places become regard to the detri- of these stones when have ae geen fund here these stones when eaten have Peravenéss or gripes. We believe the outer covering in these cases was not removed prior to eating. It has been found upon experiment that the white kernel inside the stone 1s nutritive. According to the Ayurveda system of (JANUARY, 1909. science, these stones when pulverised are used in cases of rheumatism. Accord- ing to the Unani system of science, the pulverised powder is used in cases of ringworm. Dr. White says: “The powder can be used asa poultice over the boil.” From the pestled stones, when boiled, a sort of gruel is obtained, and this is much used in weaving silk cloth. It is also used for binding books and for making leather harness. Its sticky substance is again used for joining broken wooden bars, ete. {[t has become known from an account writtensome fifty years ago in an Agri-Horticultural Journal that a kind of oil was obtained from the stones of the tamarind. The quantity of oil obtained from the stones was small compared with the labour required to undergo for producing it, besides no standing business has ever been heard to have been lucrative from the sale of this oil. We, however, think that an industry can be easily got up in the market from the stones of the tamarind; in our ignorance we throw away much of the wealth lying at our door. The stones can be easily brought from the villages, and with the aid of an electric flour machine these can be pulverised into flour. A small capital is required to start a business. We hope some of our readers will make an experiment in this line of business.—Indian Heonomist. COCONUTS IN THE DRY ZONE OF CEYLON. By J. C. WILLIS. (Illustrated.) There appears to be an_ impression abrcad that the coconut will not grow in the dry country of northern Ceylon. That this is untrue may be seen bya visit to any village there, where the tree may be seen Aourishing in the neighbourhood of the tank, in which place it gets acertain amount of seepage. A little water, but only a little, is required for the successful cultivation of this tree. The photographs reproduc- ed with this article show the early stages of cultivation on the irrigable land at Maha-iluppalama Experiment Station, 11 miles from Kekirawa (north of Dambulla on the great North Road). The younger trees occupy 27 acres on irrigable land, about half a mile from the tank. The seed nuts were put into the nursery in August, 1907, and in April, 1908, they were planted out in holes of — 3 feet cube, partly filled with soil. COCONUTS IN THE DRY ZONE OF CEYLON. On IRRIGABLE LAND. o he Air JANUARY, 1909.] 27 Drains were then cut, and they were watered from the tank ela, once a month for one day, until September, since when they have not been watered, and probably will not want any more. The older trees were planted out on six acres of unirrigable landin May, 1907, but about 200-500 yards from the tank, where there must probably be some seepage. They were watered at inter- vals of 14 days till the N. E. monsoon. In places they were watered twice in June and July, 1908, and have had no other water. The ground could not be cultivated till after the photograph was taken, but a space was kept weeded round each tree. The irrigable land is in a fine state of tilth, it will be noticed, the tracks of the teeth of the Plant Cultivator showing clearly. The unirrigable land has been tilled since the rains, but at the time of these photographs (Aug. 24, 1908) had not been tilled. These photographs show the possibility of cultivating coconuts successfully on the tank lands, with the use of the very smallest amount of water. The growth of trees at Peradeniya, from seeds from the same tree, and of the same age, is by no means so good. There can be no doubt that the irri- gable land of the dry zone is the “ best unrealised asset ” the island has, and we hope to see it the seat of a large agri- cultural enterprise. THE COCONUT PALM: ITS RELA- TION OF WEATHER TO CROPS. The following paper was. read by Mr. J. D. Vanderstraaten, at the meeting of the Board ot Agriculture on 3rd December, 1908 :— The want of literature ox the coconut palm has been often noticed, and is re- markable considering the great value of the palm to this Island. It not only contributes largely to the good of the people, and is directly or indirectly their chief cource of income, but it furnishes the Government with 12 per cent. of its Revenue through arrack rents, and supplies the magnificent Harbour of Colombo with more than half of its ex- port shipping tonnage, and may well, if the cultivation of the palm be encouraged and stimulated, supply quite two-third to three of the tonnage. The American Government, shortly after the acquisition of the Philippine Islands, began the scientific study of the coconut palm, which previously had not been, I believe, Edible Products, the subject of scientific investigation ; and itis very desirable that the Ceylon Government should, if it has not begun already, undertake researches into the life history and cultivation of the coconut palm on almost the same lines as the valuable researches concerning Para and other rubber-yielding trees. For, al- though the coconut palm is such a familiar tree to us all, as usual with all things with which we are familiar, accurate knowledge is wanting and much error prevails, some of aserious economic nature, é.g., it is generally believed by the larger proportion of coconut garden owners (am I overstating it when I put it quite as high as 90 per cent?) that manuring is ultimately and soon hurtful to the tree, even fatally so, though at first attended with some increase of crop ; this I say is a serious economic error, for the produce of the coconut plantations in the Island may easily be at least doubled by manuring the gardens. The experience of those who have cultivated and manured gardens previously innocent of either tillage or added fertilizers, has been that a three or even fourfold in- crease may be obtained and permanently maintained, without any shortening of the life of the trees. But, to convince the people of this and of it being quite within their means to properly cultivate their lands, it would seem necessary that a Government scientific department shouldcarry out experimextal cultivation and issue manuals in the vernacular, giving the results and all required directions. The advantages that would result to the country, to the Government and to the people within less than a decade, would be incalculable. Amongst other misconceptions about the coconut tree may be mentioned the general belief that each tree bears twelve bunches of fruit a year ; that heavy rain is beneficial, and the heavier the more beneficial; that, on the other hand, drought is hurtful, even drought of the kind that ordinarily prevails during the early months of the year. In this paper I propose to consider the relation between the weather and crops, and it is not inopportune, seeing that the rainfall this year has been throughout the Island much below the average, and in some districts the drought has been unpre- cedentedly severe, as in the Puttalm district. At the outset I must disclaim having definitely succeeded in tracing the exact time relative between the weather and crops. I. have formed a theory out of some data where many nezessary data are required for accurate conclusions. It is with a view to elicit discussion and Hdible Products. to have my theory confirmed by others, or satisfactorily controverted, that I venture to submit this paper. That there must be a relation between the weather und coconut cropsisa simple truism, but can we reduce it to rules for our guidance in estimating future crops or in devising measures to counteract the effects of unfavourable weather? The ‘question is not one merely of the amount of rainfall in a single year (the tree is one that is blossoming and bearing fruit all through the year), but of the intensity of the rainfall at various times, of its distribution, of the degree of saturation of the soil, the variation in the saturation from thorough as in the early weeks of the monsoons to greater or less dryage during drought, of the variation in the temperature and moisture of the air, the degree of sunshine and light as affecting transpiration and the formation of chlorsphyl, and also the eletrical condi- tion of the atmosphere, We all know roughly that extreme and prolonged saturation of the soil, as also extreme and prolonged dryage, are equally unfavourable. We know that extreme heat and extreme cold, that a prolonged period of dark cloudy days are all unfavourable to the production of blcssom, while it has been generally noticed that a highly electric condition of the atmosphere is extremely favour- able, but here our knowledge ends. When we enter into details our opinions differ greatly. We have not before us allthe data for definitely framing our opinions, and it is extremely desirable that full observations should be carefully recorded of the various tactors that affect coconut crops. The experience of practical planters of the results of manuring and recorded observations of rainfall and crops should goa long way towards establishing a fairly workable theory on this subject. In manuring, especially in manuring a previously uncultivated garden, we find no increase in the crops during the first year, simply because the blossoms for the first year’s crops were all out and set, and in various stages of development already when manuring took place— perhaps after afew months we find less of the tender young coconut (kurum- bettis) falling, owing to the increased nourishment afforded by the manure, so also we notice a slight improvement in the kernel from the same cause. During the second and third years there is a marked and gradual increase of crop still due to the improved vigour of the trees and the consequent fertilizing properties of the pollen which otherwise would have been largely infertile. The increase of crop during the third year 28 may be quite double the previous yield or even more, but it is after the third year that the full effects of manuring are felt by the trees, the increase in nuts of previously unmanured gardens being quite four to fivefold. I was much struck with this fact when I first began coconut cultivation and unable to account for the long interval required for manuring to tell in the case of coconuts, till curiosity led me to dissect the heart or cabbage, the pol-bada, of a healthy tree which was blown down by high wind. Count- ing all the flowers from the one just opened to the smallest spathe in the heart or cabbage that could be examined. with a magnifying glass, I found there were thirty-four flower spathes in this tree, and the smallest spathe in the heart of the cabbage had clearly distinguishable miniature kurumbettis or female flowers. Now, taking sixteen as the average number of fresh branches (and each branch carries a flower spathe) put forth yearly by a healthy tree, we get two years and say twoor three months for the last distinguishable spathe to arrive at the crown of the tree and burst into blossom—to this must be added another ten to twelve months before we can gather the fully matured nuts from that branch. This gives us the period of three years at least, and I suppose a few months must be allowed from the beginning of the manuring period for the initial forma- tion of the flower spathe in embryo. IJ regret being unable to express myself in scientific terms. Scientists whom I have consulted tell me the flower spathe once formed inembryo, nothing can in- crease or diminish the number of female flowers it contains. May we not well conclude that rain or drought, too, in- creasing or retarding the flow of fluid (sap) in the trunk of the tree and otherwise affecting it, cannot increase or diminish the embryo female flowers already formed, and must therefore take the same timefor its operation as manuring. The records of crop and rainfall kept by some estates bearjout also, I think, the theory | have advanced. These records also [I think establish the fact that heavy and long continued_ rainfall, lead- ing to prolonged and undue saturation of the soil, prejudicially affect the for- mation of fruit blossoms; but when a period of dry, sunshiny weather, almost amounting to drought (as in the early months of the year), follows on such heavy rainfalls, the conditions are ex- tremely favourable. The coconut tree thrives best with its crown exposed to the sun and wind (favouring transpiration, and in conse: [JANUARY, 1909. | | January, 1909.1 29 quence through the circulation of the sap the absorption of moisture from the ground. The rootof the tree should be in favourable soil with easy access to running water. We find the coconut tree flourishes into an average rainfall of 80 inches as in the Negombo district, and of about 50 inches as in the Puttalam district, but if the occasional torrential downpours which go tomake up the total of 80 inches in the Negombo district are allowed for, the average would be about 50 inches—even 40 inches are not too low. It is necessary to avoid the extreme and prolonged saturation of the soil by drainage, when necessary, and the ex- treme dryage of the soil by tillage and mulching and also to increase the vigour of the trees by fertilizers to enable the roots to penetrate down in search of moisture when the surface supply is scanty in times of extreme drought. The drought this year has been excep- tionally severe. but when the land has been well tilled and mulchedI do not think any serious harm has been done. In the Negombo district I can only trace the present effect of the drought in the thinness of the kernel we have been desiccating lately. Where the coconut roots have had access to water I do not anticipate any shortage of crop three years hence, but quite the contrary. If owners of coconut gardens would even till their lands well (by ploughing or turning on the soil toa depth of 5 or 6 inches) and spread coconut fibre refuse— a cheap and satisfactory mulch to be had for the cost of transport—or use some other mulchy substitute, they will not even suffer the loss of tender nuts dropping in consequence of any drought that may prevail. Mulching has this to recommend it, that it not only prevents rapid loss of the moisture in the soil by capillary attraction, and so conserving it for the use of the tree, but by obstruct- ing evaporation prevents the cooling down of the soil, which always requires to be warm for production of fruit blossoms. THE INDIAN TEA TRADE IN 1907-08. A PROSPEROUS YEAR. The following particulars are extracted from the *‘‘ Review of the Trade of India” in 1907-08 :— The Indian tea trade has enjoyed another prosperous year. The World's consumption has apparently caught up supply, and everything points to its increasing in the futurejat a correspond- ing ratio. The only ms Edible Products, DISQUIETING FEATURES of the year’s trading were the temporary inflation of values for lower grades of leaf, which have appreciated by 70 per cent. since 1906, at the expense of the better teas, and complaints of a general decline in quality; but the principal excuse for coarse plucking has been re- moved, now that tine market seems to have recovered its sense of proportion. In any event India could not hope to have benefited long by the extravagant rates for her poorer stuff, for they would have provoked the competition of the cheaper China tea and encouraged in- creased cultivation in Java. THE ADVANCE IN CONSUMPTION, which followed the reduction of the import duty in the United Kingdom to 5d. per lb., has been maintained. In- ternal absorption is increasing and tea shops are now a common feature of many bazaars, particularly in Southern India; but it is in the expansion of the Con- tinental markets that the prospects of the Indian industry centre, and of these the Russian market in particular is showing remarkable development. The following table illustrates in the last three calendar years, compared with the year 1890, the astonishing growth in absorption of teas from India and Ceylon on the Continent :— 1890 14,001,824 lbs. 1905 129,881,250 ,, 1906 oe ae 162,461,824 ,, 1907 (estimated) ... 171,500,000 ., THE RUSSIAN MARKET is of particular interest and importance. Its development dates from the discovery that Indian dust gives a greater strength to ‘‘tablet” tea than Chinese. Indian tea reaches Russia not only by direct shipment, but also across the land frontier of India and by re-export from the United Kingdom, Germany and China. It has been estimated that Russia in the nine months ending September 30th, 1907, absorbed 30,542,081 lbs. of Indian and Ceylon teas as compared with 24,566,329 lbs. for the same nine months of the previous year. These figures exclude imports of brick tea from China, in which Indian dust has been blended, estimated at 8,000,000, lbs. in 1907 or proportionately 6,000,000 lbs. for the period January- September. Indiais encouraged to direct importaion into Russia by the pre- ferential duty on her tea and that of Ceylon carried by the Trans-Siberian Railway, and it is announced in this connection that a double service of steamers will be established next season.

The duty on tea in Germany was reduced in 1906 to 14d. per lb., and this, aided by a vigorous medical campaign against beer and coffee, is likely to encourage imports. Holland and Belgium are two other promising markets. As regards the COMPETITION WITH CEYLON, it remains to be seen how far the intro- ducticn of rubber there will ultimately affect production, for the cultivation tends to oust tea from lower levels where the yield is generally greater than at [JANUARY, 1909. RESULTS OF IMPROVED PROSPECTS in the tea trade are illustrated by the appreciation of shares in the market. Mr. George Seton has calculated that the shares of 170 Tea Companies registered in London have enhanced in value from £14,400,000 to £21,600,000, or by no less than 50 per cent. between January, 1905, and November, 1907. China supplied half the requirements of the United Kingdom twenty years ago ; in 1907, the proportion had been reduced to six per cent. and is only sustained at that level by the com- petitive price for lower grades of Indian and Ceylon teas. Theimports of tea into the United Kingdom in 1907 were as higher altitudes. The follows :— 1906. 1907. Million lbs. Per cent. Million lbs.

The expansion in the Ceylon. and China figures is due to Russian requirements, and the heavy decline in direct ship- ments to Canada should not be regarded as an index ofa contracting market. Russia and Australia have made marked advances, ‘Lhe figures to Australia were swelled by a replacement of the ship- ment of 750,000 Ibs. lost by fire on the ss. Fortunatus. Another feature of the year’s trade which should be noticed is the increase in volume of sales by auction in CALCUTTA IN PREFERENCE TO MINCING LANE. aud London has further suffered as the emporium of imports into the United Kingdom by the competition of lower JANUARY, 1909.] freights with Glasgow and Liverpool. About 73,200,000 lbs. were auctioned in Caleutta during the past season, of which only about 20,000,000 lbs. went to London, and of the balance Russia (direct and through China and Ceylon) absorbed 27? millions and Australia 10? millions.

Taking the population of the province as at the last census, the quantity of tea consumed annually is about two pounds per head of popula- tion. The advance in the consumption of wet or pickled tea was 398,000 pounds. During the financial .year 1907-08 the quantity of pickled tea imported from the Northern Shan States was 16,359,878 pounds, and dry tea 2,477,952 pounds, besides 1,389,000 pounds imported by sea. The wet or pickled tea is considered a luxury by the Burmans. The trade of the province is altogether in a very healthy condition. The total value of the inland foreign trade shows an in- crease of 376 lakhs, or 34°76 per cent, over the figures of the previous triennium. Ot this amount 164 lakhs represents the value of silver, and the remainder Edible Products. merchandise not including timber. Im- ports contributed 20°73 per cent. and exports 52°47 per cent. to the increase. Elephant stealing in the forests of Siam hampered the imports of teak timber, and the great murrain among cattle in Western China and the Shan States accounts for a heavy decline under that head, but the total trade for the official year 1907-08 amounted to 534 lakhs, an increase of 9°46 per cent.—Indian Agri- culturist, Vol. XX XIII., No. 9. MANIOC OR CASSAVA. By EDWIN B, CoPELAND. (Continued from p. 529.) CLIMATE AND SOIL. Manioc is essentially a tropical crop. Even the hardiest varieties are killed by any frost that kills tomatoes. As a result, growers in the United States must use the earliest varieties and harvest their crops in from seven to nine months after planting. The average yields with decent cultivation are not over five tons of roots per acre. This is as high a yield as c ould be counted on in the Philippines in the same time; in the variety thatis raised here, it is after this age is passed that the most rapid growth occurs. As the plant is repro- duced by stem cuttings, it is necessary ina country subject to frosts to bury the stems during the winter. This makes seed material somewhat expen- sive and of low vitality, so thata con- siderable percentage of the cuttings set out are likely not to live, and this in turn leaves vacant spots in the field and cuts down the yield. Itis only in lands nearer the equator, where the temper- ature is comparatively uniform and moderately high, that manioc can develop with its characteristic luxu- riance. An altitude of 3,000 feet is the upward limit of the common occurrence of manioc in Hawaii;inthe Philippines its culture for food can well be carried higher. Aside from the fact thatit must be warm, manioc is very modest in its demands upon the climate. To drought, the arch enemy of most cultivated plants, it is fairly immune. For the month or so after the cuttings are planted, they need as much rain as do most other plants at the same stage of growth, After this time, a moist temperature and occasional rain pro- mote a most thrifty growth and _ the succulence of the roots. Roots used for food have a better texture in wet seasons than in dry. Dry weather, however, | JANUARY, 1909. at least such dry weather as occurs in the Philippines, never kills manioc, and rarely, if ever, comes near stopping its growth. The typical insular climate, with a moderate amount of moisture in the air at all times, is most favourable formanioc. Never is it seriously injured by any drought occurring in these Islands, and it is likewise not hurt by heavy rainfall, unless it grows in heavy and undrained soil. As is true of all drought-resisting plants, manioc wants all the light it can get, and plants at all shaded or planted too close together must not be expected to be very productive. The ideal soil for manioc is rich, fairly deep, and open. Since very rich soils are often compact and heavy and undrained, and since its tolerance of drought makes it thrive better than most cultivated plants on sandy soils, these are in many places regarded as especially favourable to it. The roots do not endure standing water in the ground around them; low, heavy soils should therefore be drained or used for some other crop. When heavy soil is used in Jamaica, manioc is planted in raised ridges, and this is the general practice in the French West Indies. The harvesting of the roots will ob- viously be easier and more complete in light than in heavy soil. As to the demands of manioc on the food in the soil, there are two opposite opinions, some writers claiming that it is conspicuous among cultivated plants for the rapidity with which it exhausts the soil; others, that it is like other starchy crops in taking very little from the ground. The former view is supported by, and is probably due to, the fact that in the Straits Settlements, Africa, and to a great extent inSouth America, manioc is raised on forest clearings, which are used a few times and abandoned, When starch became a staple product of the Federated Malay States, a large amount of land was cut over in this way and then abandoned, with the result that the destruction of the forest was out of proportion to the permanent agricultural develop- ment. The Government met this diffi. culty by refusing to lease Jand for manioc cultivation unless some _per- manent crop, such as coconuts or rubber, are planted at the same time, and this regulation has been widely const:ued as evidence that manioc is a robber crop. But it is no peculiarity of manioc that it thrives best on virgin soil. Various Philippine crops, including upland rice, are raised according to exactly the same system, and one of the hardest problems in forest regulation here has JANUARY, 1909.] been the constant abandonment of plats of cultivated land and_ the making of new “caingins” or clearings for temporary use. Chemical analyses do not at all support the view that manioc isa hard crop'on the soil. . The total ash in the roots is commonly less than 2 per cent. of the dry weight, and the nitrogen hardly more than 0° per cent. Manioce does use nitrogenin the forma- tion of hydrocyanic acid, beside in the Ways common to most plants, and may therefore exhaust this food dispro- portionately. This danger can be avoid- ed by raising a leguminous crop with the manioc or alternating withit. The most promising leguminous crop here is the mongo. Unless the soilis rich in lime, the addition of this cheap food will be good for both the mongo and manioc. ENEMIES. A scale in Africa causes yellow spots on the leaves and leaf-minor lives in them, but neither causes appreciable damage. The same is true of insects which occasionally gnaw them. Old roots left in the ground in the Philip- pines are often chambered or consumed by insects, but young or fresh roots are never attacked. Leaf-spot fungi occur in the Malay States, Africa, and, America, but no- where do appreciable damage. The only known serious disease of manioc is a leaf curlin East Africa, called by the natives ‘‘maratschi.” It is a communi- cable disease, but no micro-organism is known toecauseit. No variety of manioc is free from it. A Madagascar variety called Mpesazi, is the least generally attacked. A sound plant of this variety twelve months old may have 12 kilograms of rooots, but the average yield of thirteen plants with the leaf-curl was only 0°41 kilogram. No disease of manioe is known in the Philippines. Their most dangerous enemy here isthe hog. Wild hogs do considerable mischief when they get access to manioc, but they of course can be kept out by good fencing. CULTURE. Knowledge of what is really best in the culture of manioc is very limited, the plant never having received a frac- tion of the study which has been bestowed on all the important crops of temperate lands. On manioc we have for the most part only scattered observa- tions, and these are not always _ too reliable. In the equatorial belt, where manioc thrives best. the most usual treatment of it is the most complete neglect. The only attention it usually receives in the Philippines is sticking 5 38 Edible Products. the cuttings into the ground and digging out the roots; and in parts of India, Africa, and South America it receives no more care. The most careful study has been given it in Florida and Jamaica ; in the former all the conditions are very different from those here, and in thé latter the subject most studied has been the selection of varieties. Manioc is in practice always reproduc- ed by stem cuttings. Seeds are used in the Government work in the United States in attempts to secure new and -sweeter varieties, and in German Hast Africa in attempts to secure immunity from disease. So far as limited and unsatisfactory experiments show, the seedlings are likely to have sweeter roots than their parents. However, in Paraguay the seed of the sweet culti- vated varieties is said to be very unreliable and likely to produce poison- ous roots. The stems will grow if used as soon as cut and are presumably most vigorous then; but they have stood shipment from Jamaica to India, and in Paraguay have been kept alive through six months of hot weather, provided the epidermis was not bruised or broken and they were kept dry. Only sound stems of sound plants should be used. Cuttings 10 to 20 centimeters. long will produce thrifty plants. Some writers advocate the use of longer ones, and it may be that their use where there is plenty of material for propagation will give the plants a stronger start. The cuttings are buried horizontally in some places, placed erect with the lower end in the ground in others, and planted obliquely in still others; they grow everywhere. The crop will perhaps be more easily har- vested if the cutting is not erect. If it is erect it is advisable to plant in the ground the original lower end, so that the polarity of the cutting will not have to be overcome when it begins to grow. Statements as to the proper distance between plants differ widely, and this depends of course upon the soil and climate, and upon the natural growth of the variety planted. - On good soil a distance of one meter in each direction can be recommended for the Philippine variety; this puts 10,000 plants on one hectare of even ground. If more room for cultivation in one direction is desired, the same stand can be obtained by putting the rows 125 centimeters apart and the cuttings 80 centimeters apart in the rows. A somewhat more ample spacing is better, if a short-lived catch crop is interplanted, Some writers condemn the use of any other crops with manioc, but it seems to me that if well chosen they have decided Edible Products. 34 advantages. Theuse of cane in this way— as is practised, for instance, in Mauritius and Reunion—is distinctly bad from the standpoint of either plant, for they compete throughout their lives and reach their greatest development at the same time. Maize is used on a plantation in Basilan, and is harvested and out of the way before the manioc needs all the space. But if a catch crop is to be used, there is no reason why it should not be one which, like mongo or some other legume, will leave the soil actually bettered by its presence. There is at our door a market for mongos as human food, and there are various legumes which produce a fodder which could be mixed with the waste from the starch mill to make a well-balanced fodder for beasts. While, so far as I know, no comparative tests have been made, there is no doubt that thorough ploughing and harrowing have the same general effect on manioc that they have on other crops. In the case of manioc, hard ground not only prevents the proper growth and activity of the feeding roots, as it does for other crops as well, but it interferes directly also with the development of the part of the plant to be harvested. Even if the fleshy roots became as large in hard and uneven ground—-which they could not— they would still be less valuable, for it is much more difficult to clean and peel an irregular root than a stout, symmetrical one. Moreover, as has been seen, the bark and cortex are strong in hydrocyanic acid, while the starch is cunfined to the fleshy interior; therefore a stout and symmetrical root, having less surface in proportion to its bulk, will contain the least poison and the highest percentage of starch, while an irregular root or a very long one, such as may grow where the ground has been cracked, will be comparatively bitter and weak in starch. While ploughing is, in the abstract, desirable, we may as well recognize frankly that on freshly cleared tropical land it does not pay. The laborious removal of stumps and roots, work to which the native labour is not used, costs fully as. much here as in the United States; while if fresh growth is kept down, termites and the teeming organ- isms of decay will destroy almost every kind of wood completely within a year or so. The land can be ploughed for subsequent crops. Hand cultivation is cheap here, and can be made to give very good results. When manioc is planted on » unploughed land each cutting should be set into a spot of thoroughly worked ground 20 centimeters deep and at least 30 centimeters in diameter. The plants [JANUARY, 1909, should be in rows, as regular as possible. Because of stumps a given area will take less plants than could be put into land well cultivated. If mongo is interplanted with manioc the two should be planted at the same time, so that the mongo may mature and be harvested before the manioc needs its room. It, as has already. been suggested, the rows of manioce be 125 centimeters apart and the cuttings 80 centimeters apart, two rows of mongo, themselves 30 centimeters apart, can be planted between each two rows of manioc. The two crops will need but little more cultivation than should be given manioe alone. Whether or not the mongo is present, the land should be thoroughly cultivated not more than one month after planting, making the ground soft and fine, and killing all weeds—a weed is a plant of whatever kind which grows where it is not wanted, At this first cultivation itis advisable to hill the manioc slightly. Mongo needs cultivation twice within the first two months, while manioce might do with one, but will certainly grow better for the greater attention. After the mongo is removed the ground will still want to be cleaned and worked once. After the plants are four or four and half months old they take care of themselves. The roots areready to be used for human food at any time after they are five or six months old. Sometimes all the roots of a plant are taken at once, sometimes they are dug one at a time. In these young roots the percentage of sugar is probably as great as it ever becomes, but they are relatively weak in starch, and less woody than older ones. The roots of the Philippine varie- ties are probably best suited for direct use as human food when they are not more than nine months old, although we have seen succulent roots on plants said to be sixteen months old, from which other roots had been removed earlier. In Hawaii, two year-old roots are often hard and _ fibrous, containing little starch, One African variety is edible when six years old. For making meal or manutacturing starch the reots ecan- not profitably be gathered until they are well beyond the best age for direct use as human food; thus, in one African district they are eaten fresh when about nine months old, and not used until twelve to fourteen months old for making meal. In some parts of the Philippines the roots are said to be grated and eaten when three years or more old. (To be continued.) JANUARY, 1909.] 35 THE FERMENTATION OF CACAO, By Oscar Lorw, Physiologist. (Concluded from page 534.) Since a moderate brown colour is also produced in white ‘‘nibs,” free of cacao red, it follows that the brown colouration is not due exclusively to a change of eacao red. If the production of the colour is due to an incomplete oxidation ot the tannin, then there will be less tannin found in the cured cacao than in the fresh cacao. This agrees, indeed, with some analytical determinations of J. B. Harrison, published by Hart. The fat content is assumed not to change during the curing process, and this is in all probability the case. The data com- piled under this condition are as follows for Calabacillo cacao :— ANALYSES OF CALABACILLO CACAO. 1 : Fresh. Cured. Constituents. Panice “Pat ct.

This would account for the decrease of starch, glucose, and hemicellaloses, which. may be consumed by the respiration process, but the other changes are due to several enzyms. A _ proteolytic enzym brings on the decrease of protein and the corresponding increase of amido-com- pounds, while oxidizing enzyms, generally liberated from the protoplasm upon its death, cause the decrease of tannin and cacao red and their change to other compounds. The most conspicuous changes are, therefore, only possible after the death of the protoplasm which isa desirable factor, Hence, it is a mistaken idea of Zipperer that the changes are due to a germination process of seeds. He has even attributed the rise of temperature of the fermenting pulp cacao to this process, considering it analogous to the behaviour of barley on the malting floor, This error can only be explained by the fact that he has never witnessed the fermentations of cacao or coffee; for germination changes are not in the least apparent, Edible Products. Another result is the change of flavour. In the fresh state the seeds have a raw bitter, and astringent flavour, while after fermentation and drying the bitter and disagreeable taste has entirely disap- peared. This change is doubtless due in a certain measure to the decrease of tannin ; that is, to its change by oxida- tion to abrown substance, as inthe case of the persimmon fruits, mentioned above.* The flavour of the fermented beans is still far different from that of the prepared cacao product, which is produced by roasting the fermenting beans; hence a part of the taste must be due to changes caused by the heat of the roasting process. The presence of oxidizing enzyms in the seeds of cacao can be proved by the usual reaction. Upon moistening a freshly cut section of cacao seed with tincture of guaiacum resin, just after taking the seed from the ripe fruit, a blue colour is rapidly produced, first and most intensely in the chalaza of the embryo and gradually spreading over the entire seed tissue; also, the placenta shows soon an intense blue colour. Whena cross section through the whole fruit is moistened with guaiacum tincture, the chalaza of the embryo and the interior soft stratum of the fruit shell become rapidly and intensely blue, then follow in order the colouration of th2 convulsions of the cotyledons, of the seed and the tissue of the hard outer shell. Finally, the whole surface of the section of the seed and exposed tissue of the testa become blue ; but the slime tissue or pulp around the testa remains perfectly colourless, presenting a most striking contrast. If the tissue of the seed is crushed with some water in a mortar, the filtered liquid will show no blue colouration on addition of guaiacum tincture and shak- ing with air, while the unfiltered liquid will become blue very soon. This shows an exceptional case, namely, that the oxidase (laccase) is present in an inso- luble state and perhaps held in combi- nation with an _ insoluble protein.t Upon standing the blue colour, obtained with the unfiltered liquid, will gradu- ally disappear, except on the surface, but on adding afew more drops of the reagent and shaking, the intense blue colour reappears. This phenomenon is due to the presence of a reducing com- pound in the juice. *The opinion of Harrison mentioned above that the decrease of the astringent taste is dueto a hydrolysis is erroneous and would be without analogy. _ {This recalls the existence of a soluble and insoluble form of catalase, Edible Products. 86 In testing for a second oxidizing enzym, the peroxidase, the tissue of the seed, crushed witha little water, was heated for five minutes to 75° C, and one portion of this liquid was filtered, the other not. The test with guaiacum tincture yielded no blue reaction in either liquid, proving that the oxidase was killed, while on addition of a little paroxid of hydrogen the unfiltered juice gave an intense blue reaction and the filtered juice showed only a trace. This difference proves that the peroxidase, like the oxidase, was present, but retained as an insoluble compound—an exceptional case. Reactions with guaiacol were also tried, This substance produced no coloration when applied by itself, but in conjunction with hydrogen peroxid a red colour turning to brown was soon produced in both the hard as well as the soft layer of the fruit shell. Later, in the testa and the; seed in general, as well asin the slime tissue covering the testa, only a weak, reddish coloration was produced. This peroxidase reaction agrees also with that just mentioned, in so far as the slime tissue gave only an exceptionally weak reaction compared with all other parts of the fruit. The slime tissue of the coffee fruit is also poorer in oxidase and peroxidase than the other tissues. The further generation of the charac- teristic aroma of cacao is of great im- portance. Is this process due to the action of an oxidizing enzym or to that of a hydrolizing enzym, and does the fermentation influence the generation of aroma only indirectly by the develop- ment of heat or directly by furnishing some compound? Or, is the roasting of the fermented cacao beans alone res- ponsible for the aroma? The investiga- tions thus far made do not solve this problem satisfactorily. It may be men- tioned, however, that Hart agrees with Chittenden, .who declared that after a certain stage of the fermentation ‘‘ the cotyledons are found separated and the vinous liquor of the pulp, which passes through the membranous covering, occupies this space as well as the cavities between the convolutions. unis ee Eis it is which hasso marked a physiological influence and affects its flavour, the bean being, as may be said, ‘stewed in its own juice.’” According to the laws of osmosis some acetic acid aud some alcohol from the fermenting liquor will doubtless enter through the testa and come in contact with the cotyledons, which thereby may be killed, if the temperature of the fermenting mass has not already accom- (JANUARY, 1909, plished this. The reaction of the cotyle- dons after drying the fermented beans is acid, but whether thisis wholly due to the entering acetic acid may be doubt- ful, since the reaction is weakly acid in the fresh state. A stronger acid reaction is shown by the slime tissue. The expression ‘‘stewed in its own juice” used by Chittenden can hardly be admitted, since the juice of the pulp, after being entirely decomposed by yeast and bacteria, is certainly not the ‘‘own juice” of the cotyledons. Still, that author attributes to it the gener- ation of the flavour. The opinion of J. B. Harrison that the decrease of tannin during the fermenta- tion process stands in relation to the development of aromais certainly far from the mark, as tannin cannot produce ethereal oils by an oxidation or fermenting process. Only colour and taste stand in this relation to the tannin content. Several experiments were made by the writer with an aqueous solution of 1to4 per cent. acetic acid containing from 8 to 5 per cent. of alcohol in order to imitate the composition of the fermenting pulp juice. After twenty to thirty hours’ digestion of pulped cacao at 40° to 45°C. it was observed that the pulp had died and shrunk to skinny masses, partly separating in small pieces, but mostly still firmly adhering to the testa. It appears that for bring- ing about an easy separation of the dead pulp from the testa a bacterial enzym is necessary, as in the case of coftee fermentation. It was further observed that the amount of acetic acid, which entered by osmosis through the testa to the coytyledons, was not sufficient ‘to kill the oxidizing enzym, since the freshly cut surface of these seeds rapidly turned brown on exposure to the air. On the other hand, it was observel that when the freshly cut surface of the seeds so treated was moistened with 4 per cent. acetic avid no further change by oxidatiou took place. In this case the oxidizing enzym was killed. Itis stated by Hart that ‘‘ of late years there has been a large amount of inquiry for cacao which is but slightly fermented or not fermented at all.” This renders it very probable that the decomposed juice of the slime tissue is not required for the generation of the aroma as was supposed. Indeed, the true aroma of cacao is faint before roasting the fer- mented beans. The case is, therefore, similar to that of coffee, and is different from that of tea. With tea the aroma is the result of the action of ahydrolizing enzym, yielding the volatile tea oil, as was shown by Katayama. itt: we January, 1909.) That the aroma of the cacao is chiefly produced during the gentle roasting process is the opinion of manufacturers of chocolate from the fermented beans. The fermentation seems, indeed, to have nothing at all to do with the production of aroma. Seeds simply dried in the sun and then gently roasted may yield an especially rich and aromatic chocolate, as Safford* has also indicated. Hart says: No adulteration ~ * * isequal tothe flavour of the virgin cacao, provided the essential oil has not been destroyed dur- ing the process of roasting, during which process it appears to be developed.t The question now arises, which com- pound yields the aroma in the cautious roasting of the fermented cacao beans ? It is certainly not.a glucosid, for neither the testa nor the cotyledons of the beans develop anything like a cacao flavour upon being boiled for some time with dilute sulphuric acid (8 to6 per cent). The same negative result was obtained by boiling those materials with moder- ately concentrated solution of caustic potash. It seems probable that it is a certain concomitant of the fat which causes the production of the flavour, after being moderately oxidized during the drying of the beans. Only seeds which the oxidizing enzyms have pro- duced changes can yield the true aroma by roasting, not the fresh beans.} In the manufacture of the cacao powder of commerce the fat of the cacao is removed more or less, since a suitable powder cannot otherwise be obtained, but in the direct manufacture of chocolate this removal of the cacao fat cannct be justified. Itis claimed that cacao fat or cacao butter is difficult of digestion, but in reality cacao butter is as easily digestible as cow's butter. Besides, the removal of fat also diminishes the aroma of the chocolate. In _ the manufacture of chocolate in Porto Rico, fermented cacao seeds are placed in a small baker’s oven for about one hour, until the testa have become very brittle * Compare the quotation in the introductory remarks to this article. + These words contradict his other opinion, however, quoted above in regard to the in- fluence of fermentation on aroma. + Fresh beans were crushed, washed with alcohol, and extracted with either. Neither the extracted fat nor the seed powder developed on moderate heating any flavour resembling that of cacao; only the alcohol extract yielded thus avery faint flavourof cacao. On evaporation of the alcoholic extract another aromatic odour is noticed. Edible Products. and can be easily removed. This roast- ing temperature is kept considerably lower than that required for baking bread. The cacao butter is not removed in Porto Rico, and therefore the chocolate manufactured there has an exquisitely fine aroma, SUMMARY. _ The fermentation process itself is due in the first place to yeast cells which multiply rapidly in the saccharine juice oozing fromthe pulped cacao and produce alcohol and carbon dioxid. In the second place bacteria participate, which develop rapidly after a certain time, and change the alcohol formed by the yeast by oxidation, either wholly or partly, into acetic acid. These processes cause a rise of temperature and the death of the cells of the seed and slime tissue, whereupon the juice of the slime tissue, more or less altered, collects at the bottom of the receptacles, together with the acetic acid produced. The chief object of the fermentation is to shrink the slime tissue or pulpat- tached to the testa of the seed, allowing the remnants either to be washed away, as is doue in Ceylon, or dried upon the seed forming an irregular brown film upon the testa. The advantage of thus changing the voluminous slime tissue lies in the increased facility of quickly drying the seed. In this regard there exists a close analogy to the fermentation of coffee. The loosening of the adhesion between seed and its envelope and the hardening of this envelope (testa) are claimed as further effects of fermentation. _ The fermentation has also an indirect influence on changes going on within the seed, inasmuch as by the temperature produced (40° to 50° C.) the cells of the seed are killed, thus liberating the oxi- dizing enzyms, which cause the forma- tion of the brown colour, by oxidation of the tannin of the seed. This brown colouration is increased during the drying process and finally by the roasting. ; The taste of the raw cacao bean is not only altered by the partial oxidation of tannin during the fermentation or sundrying of the seed, but also by products of roasting. The action of oxidising enzyms, as well as the final roasting process, play a part in the development of the aroma, —Porto Rico Agricultural Experiment Station. For 1907.

Inthe rainy season, extending from June to December, a week of fine weather will often cause the lime trees to put out afew clusters of flowers, and it is from these minor flushes thata few fruits are procurable all the year round. The main-crop season extends, as a general rule, from June to December. Whether the main crop is early or late, whether the bulk of the crop ripens in a short period, say, from six to eight weeks, or is prolonged over several months, or whether there is an early crop in July and August followed by a distinct second crop in November and December, depends chiefly on the local weather conditions and on the vigour of the trees. Accurate observations of the length of time from flowering to the maturity of the lime fruit do not appear to have been made, but itis usually placed at five months. It depends upon the local climatic conditions and upon the vigour of the trees. The yield per acre of fully established lime estates varies greatly. Good estate cultivation should produce from 150 to 160 barrels of fruit per acre annually, but there ismuch cultivation that does not yield higher than from 80 to 100 barrels of fruit per acre. A barrel of limes gives from 73 to 8 gallons of juice, but the acidity of the juice varies according to the rainfall. An estate with a low rainfall may average 14 oz, citric acid per gallon of juice, while another with a higher rainfall may average 120z. In the very wet districts in the hills the acidity is as low as 10 oz. per gallon, The yield per acre of a lime plantation is sometimes expressed in barrels of fruit and sometimes in hogsheads of concen- trated juice. Neither conveys much meaning unless accompanied by the acidity of the raw or concentrated juice. It: would be better expressed as pounds of citric acid contained inthe concen- trated juice, for it is evident that a return of 200 barrels of lime per acre viving juice testing 14 oz. per gallon is very different to the same return per acre in barrels giving juice testing 10 oz. per gallon. Similarly with concentrated juice, some estates concentrate to 100 [JANUARY, 1909, oz. per gallon, others to 120 or 1380, and a few to 140 to 150 oz. It will be seen that there is a wide difference between hogs- heads of concentrated juice testing 100 oz. per gallon and others testing 140 oz. About eight-ninths of the lime juice produced in Dominica is concentrated for sale to citric acid makers ard to cotton bleachers. The remaining one- ninth is exported as raw lime juice for making cordial. The establishment of a citric factory in Dominica will tend probably to reduce somewhat the pro- portion of concentrated juice, for this factory takes the juice after the essential oil has been expressed and before concentration in the usual course is begun. The standard at which concentrated lime juice is sold is a pipe of 108 gallons testing 64 oz. to the gallon. Its equi- valent is a 52-gallon hogshead, the pack- age used in the West Indies testing 133 oz, to the gallon. Limes, when ripe, fall from the tree, and are collected from the ground by women and children into heaps. The usual price paid for collecting the lime is at the rate of 8d. per barrel, but this rate is increased when they have to be carried for long distances. ——————— The fruits are then put into carts and taken to the mill house for the extrac- tion of the juice. MACHINERY REQUIRED, FURL, ETc. Many of the old three-roller sugar mills placed in position when sugar was the staple crop are still in use to-day for crushing limes. The sugar mill with iron rollers adjusted to crush limes has answered admirably where the lime juice is concentrated. These are usually driven by water power on large estates, and in some instances by cattle. On small estates, mills worked by hand power are in use. a a Ee ee eee The machinery required for dealing with lime juice consists of a three-roller mill (iron rollers may be used where the juice is concentrated, but they should be of granite when raw juice is prepared for shipment for making cordial) driven by steam, water, or cattle; a press for extracting any juice that may be left in the skins after passing through the mill; storage vats; a copper still; three copper taychesin which to boil the juice; and coolers, Tron rollers should be washed down. after use to prevent the acid eating into the iron, and when raw juice is exported for making cordial, the juice should be run to the settling vats through earhten- JANUARY, 1909.} . 39 ware pipes. It should not be allowed to come in contact with metal. Works should be arranged so that the mill house is on higher ground than the boiling house. The juice on leaving the mill then runs by gravitation to the storage vats, from the vats to the still and from the still to the copper tayches where it is concentrated. It is then placed in wooden or copper coolers, and is finally run into hogsheads for ship- ment. Concentration of lime juice in copper or wooden vessels fitted with steam coils has been recommended, and would no doubt be an improvement on the present system. Itis not now likely that any great effort will be made to improve the present system of concentrating juice, as the manufacture of concentrated juice may subsequently be superseded by the manufacture of citrate of lime. The Dominica Planters’ Association when furnishing information for the revision of the pamphlet entitled Hints to Intending Settlers, Dominica, wrote that ‘for lime cuitivation a mill, mill house, two tayches, battery, and boiling house large enough for adequate storage room would cost about £3800.” The above estimate includes a small copper still. The detailed estimate is as follows :— oe 1 Copper tayche (£0 gallons) ... 25 1 ” Se COUW, Gina) bates «OO Handmill ...

Later, as the crop increases, the works would need enlargement, and a copper still and three tayches of a larger size would be required. The above plant could deal satis- factorily with the crop produced from 10 to 12 acres, but would after about the first two crops be quite insufficient to deal with the produce of 50 to 60 acres.

C, Macintyre states that the requirements of a plantation of 50 to 60 acres, turning out from 100-129 Edible Products. hogshead would be as follows :— & Three-roller horizontal mill (rollers 2 feet 6inches by 18-20 inches) say 300 Power plant for same and installa- tion (5 H.

Most of the machinery on lime planta- tions in Dominica is driven by water power, but it is doubtful whether this source of power will be made use of on new plantations, except on those that are particularly favourably situated for its installation. In most situ- ations, the cost of building an aqueduct would be considerable, and the cost of even a moderate-sized wheel would cer- tainly be greater than for an oil engine or equal horse-power. It is thought that when circumstances are favourable, a Pelton wheel would probably be the cheapest form of power, both in cost of installation and in cost of running. For boiling down the juice very con- siderable quantities of fuel are required. It takes from one cord to 23 cords of wood (according to the quality of the fuel and the degree of concentration of the juice) to boil down sufficient juice to filla hogshead. On some estates fuel is very scarce and costs from 8s. to 10s. a eord. On others, wood is plentiful and costs from 38s. to 4s. a cord. When concentrated juice is selling at normal prices, that is, from £12 to £12 10s. per hogshead testing 133 oz. to the gallon, the cost of fuel together with the cost of the packages and the high freight that has to be paid on liquid produce have to be seriously considered. The industry under such conditions cannot be said to be a particularly attractive one. At present prices are high and may remain so for several years. On estates where fuel is scarce, it has been recommended that several pieces of quick-growing eucalyptus might be planted in odd corners of the estates. Edible Products. These grow rapidly and ratoon well when cut. Once established, they would bear being cut over every two or three years, while native trees that have been cut down are not ready for cutting again for at least ten years. The fuel question is an important one in the manufacture of concentrated juice, and even if citrate of lime supersedes it, the fuel question will remain. To make citrate of lime, and todry it, will require as much, probably more, fuel than the present system of concentrating juice. LIME PRODUCTS. FRvITS : GREEN LIMEs. The early shipments of green limes from Dominica were made during 1891, when 99 barrels of fruit were shipped. From this small beginning, the present considerable business in green limes with New York and London has been developed. The export of this fruit during 1907 was 18,311 barrels, valued at £6,409. The American market demands a small fruit packed in well ventilated barrels, and the London market a large fruit packed in small crates of a capa- city of one cubic foot. A barrel holds from 1,400 to 1,600 fruits varying accord- ing to the size of the limes, and a crate from 200 to 240. Green limes are picked from the trees, and are allowed to quail for several days before they are packed. The lime, how- ever, does not apparently require the same degree of quailing as the orange does to ensure its arrival on the market in good order. Each fruit must be wrap- ped in paper, and should be very _care- fully packed, Very great care is_re- quired in gathering, handling, wrapping, and packing, to ensure the best results. The lime is used for the same .purposes asthe lemon. It iscertainly displacing the lemon, to a considerable extent, in the United States. PIicKLED LIMES. In Dominica a small business is done in shipping limes pickled in sea water. These limes gochiefly to Boston. The trade is only a small one, and during late years the export of pickled limes has fallen off somewhat. This is probably not due to a decreasing demand for pickled limes, but rather to increasing shipments of this product from other West India Islands. The average annual export of pickled limes from Dominica for the five-year period ending 1896, was 1.505 casks, for a similar period ending 1901, 1,117 casks, and for five years ending 1906, 1,000 casks. A cask holds about 2,000 limes, 40 (JANUARY, 1909. For pickling, the finest specimens of sound yellow limes are selected and placed in vats into which sea-water is pumped. In two or three days, this water is run off and fresh sea-water pumped in. This process is repeated several times until the limes are cured. The fruit is then placed in casks which are in turn filled with sea-water to which a small amount of salt has been added. The casks are then closed, and are ready for export. Raw LIME JUICE. Lime juice intended for making cor- dials and for flavouring confections requires very caretul preparation. The limes should be washed before being crushed in mills fitted with granite rollers. Only the first juice obtained by lightly crushing the fruit through the first rollers is used. The second juice and the press juice which are weaker in acid are used for concentra- ting. The first mill juice is carefully strained and placed into puncheons when quite fresh. Formerly it was run into vats, and after settling the clear juice was placed in puncheons or hogsheads for export. It is wellknown that raw juice care- fully strained and placed in packages when quite fresh will keepin good con- dition tor a considerable time, but if lime juice is exposed to the air it will gra- dually lose its acidity. The raw juice trade is in the hands of two or three firms and _ probably dif- ferent methods are employed in each case. CONCENTRATED LIME JUICE. Limes are grown chiefly for the pro- duction of citric acid only a small pro- portion of the total crop being used for lime juice cordials and for the green lime trade. In the West Indies the juice is concentrated in order to reduce bulk before shipment to the citric acid makers. It is usual to reduce by boiling 600 gal- lons of lime juice to 50 gallons of the concentrated product. Some estates, however, concentrate 10 to 1, others at 9 to 1, instead of 12 tol. Mven with low concentration there is a considerable loss of acid. When concentration is carried on to 180 and 140 oz. to the gallon, the loss of acid is very great, Planters can now test their own lime juice in the bci.ing house and thereby suve a considerable destruction of citric acid during concentration, by means of eee ee, eee JANUARY, 1909.] a citrometer or an ordinary specific gravity hydrometer, A description 0 a scale prepared by Dr. Francis Watts for use in ascertaining the strengths of solutions of citric acid and of lime juice by means of a hydrometer will be found in the West Indian Bulletin (Vol. V, pp. 236-40), while a similar hydrometer method is described in the Agricultural News (Vol. VI, p. 149.) The following extracts are taken from these articles :— ‘In preparing concentrated lime juice the concentration should be carried on until a citrometer floating in the hot juice (at boiling heat) indicates a density of 60° ‘Asthe citrometer is an instrument but little known, difficulty has at times been experienced in procuring it. Its use, however, can be dispensed with, and anordinary specific gravity hydro- meter the nature of which is universally understood, can be substituted, by making use of the fact that 60° on the citrometer is equivalent to 1°243 on a specific gravity hydrometer. ‘In this connexion the following scale may be useful :—- 50, citrometer 1°202 sp. gr. 51. >” = 1 207 93 be) 52o Pr) = 1211 3? 9? 580 29 oa 1°215 ” 99 54, 99 = 1°219 3” 99 55° 3A = 1°2238 ot, mess 56° 0 = 1:227 ee 57° ” =a e235) 33 29 58° 99 = 1 285 99 29 59° A = 1°239 she ts 60° - = 1:248 alesWine> 61° Ae = 1:248 Taney, 62° ” = 1°256 29 ” 63° a = 1:260 ae pes ‘Suitable specific gravity hydrometers graduated from 1°200 to 1°300 specific gravity ean be obtained from makers of scientific instruments at a cost of about 2s. each.’ Lime juice for concentration should, when leaving the mill, be carefully strained in order to remove all the seeds, before it is run into vats. From the vats it isrun into the still to obtain the oil, and afterwards to the tachyes to be concentrated. It has lately been shown (West Indian Bulletin, Vol. VIII, p. 171) that lime juice, carefully strained, and then settled after distillation has obtained a special market, and commands higher prices than ordinary concentrated juice. Every effort, therefore, should be made by planters to ship a high-class product, 6 Edible Products. The juice is shipped to New York or London in hogsheads of 52 gallons, where it is tested and paid for according to the citric acid contents. Buyers in London and New York pay for citric acid, and not for impurities in the juice. The presence of the latter causes great trouble to manufacturers of citric acid, and tends to bring prices down. Lime juice shouid therefore never be concentrated in iron tayches, as the iron combines with it and lowers the value of the product. Concentrated juice testing 100 to 105 oz. per gallon made of well strained and carefully settled lime juice is a black and heavy, but not a dense, liquid. When no care is taken to strain or settle the juice, the product is black, and as thick as molasses at the same degree of concentration. CITRATE OF LIME. In the manufacture of citrate of lime, the juice on leaving the mill is carefully strained, then distilled to obtain the oil, and afterwards while still hot, it is run into a wooden vat to be neutralized with chalk. Before running into the mixing vat, it would be an improve- ment if the hot juice were passed through filter bags. (West Indian Bul- letin, Vol. VIII, p. 167). At present lavigated chalk is imported, but it is hoped later to use mainly lime made locally from coral. It is generally stated that the process of neutralization should be finished with chalk, but one authority has said that finishing with lime, even when chalk has been used to start with, is to be recommended as there is thereby asaving of time and a clearer indication isobtained. Neutralizing vats are fitted with perforated steam coils in order to keep the juice hot, and toactas agitators during the time chalk is being added, during the washing process, and until the citrate is finally run into the filter bags. They must be large enough to prevent loss from overflow by the foam- ing effervescence which takes place when ehalk is added. Dr. Watts writing on this matter says :— ‘A sufficient quantity of chalk is made into acream with water and the mixture poured cautiously into the juice with constant stirring, proceeding cautiously as the acid is neutralised. To ascertain how much chalk is to be used it is best to proceed as follows: When the greater part of the chalk has been added, the mixture is well stitred and the efferve- scence is allowed to subside; a small quantity is then taken out and tested by the addition of a little of the mixture .Edible Products. 42 of chalk and water; if this produces an effervescence, more chalk must be added to the main quantity, proceeding cautiously and testing intervals, until no effervescence is produced. A further test is now made—a little of the mixture is withdrawn and heated; as soon as bubbles of gas cease to be given off, a few drops of acid (fresh lime juice will answer) are added. This will pro- duce a slight effervescence if chalk has been added in right amount, and a brisk effervescence if too much has been used. In the latter case, more juice must be added to the mixture and the process of testing repeated.’ If you add too little chalk to your lime juice, you lose someacid. Ifyou add too much, it gives the manufacturer trouble by wasting his sulphuric acid. The buyers of citrate of lime have determined to. penalize anything con- taining an excess of over 2 per cent. of chalk. After neutralization, the citrate is allowed to subside, and the mother liquor is run off through a tap fitted in the side of the vat. Hot water is then run in and steam turned on to thoroughly wash the citrate. The wash- ing should be repeated several times, the citrate being allowed to subside and the water run off between each washing. Finally it is agitated and run through a lower cap into the filter bags to drain. Afterwards, it is placed in a press to extract as much moisture as possible, and then at once conveyed to the drier. Recent experiments by Dr. Watts show that the use of centrifugals is to be recommended for removing the water from citrate in place of the press. Citrate can conveniently be washed with a small quantity of hot water while in the centrifugals, and when the mois- ture has been removed by them, it can be dried, in a much shorter time. When thoroughly dried, it should be placed in aroom to cool before being tightly packed in barrels, hogsheads, or puncheons for export. It is very im- portant thatthe citrate be thoroughly dried. If this is not done, much acid may be lost. Citrate of lime when prepared in the above manner is a white powder and should contain about 64 per cent. of citric acid. Citrate of limeis twice as bulky as concentrated lime juice, but it is not expected that freight on citrate will be higher than on concentrated juice, as shipping companies give a preference to the dry over the liquid produce, wy Ey JANUARY, 1909. _ The manufacture of citrate in Dominica is as yet only in the experiment stage. Probably many improvements will be made in the process as time goes on. At present the great requirement is a drying machine that will dry citrate in a few hours without any loss of acid. The driers chiefly in use now are modelled on the cacao drier described in the West Indian Bulletin (Vol. II, p. 178). The process inthis class of drier takes too long. and the consumption of fuel is too great, for the most economical pro- duction of citrate. If centrifugals were generally adopted and an improved drier brought in use, the manufacture of citrate of lime on large estates would be considerably simplified. (To be continued.) SWEET POTATOES. (Continued from p. 548.) BEDDING THE SEED. in the warmer portions of the sweet- potato-growing district the seed should be bedded when danger of frost has passed. In the northern portion of the area the seed should be placed in the hotbed from the 20th of March to the 10th of April, after the temperature of the bed has fallen to 80° or 85° F. and ~~ become regular, If possible, select a warm, day for this work, in order that the seed potatoes and the bed may not become chilled. The soil to be used for covering the potatoes should be sifted beforehand and placed in piles in the bed, where it will have become warm and in good condition for use. Leaf mould is perhaps the best material with ° which to cover the potatoes, but where this cannot he obtained a fine, rich, sandy loam is the best substitute. Before placing the seed in the bed, an inch or more of the finely sifted covering material should he spread evenly over the surface of the regular soil in the bed, The potatoes are spread upon this bed, each one being placed by hand so that they will not touch, and about one- half of the bed surface is covered. If extra large potatoes are employed for seed they may be split lengthwise and placed with the cut side down in the bed. When the potatoes are in place, cover them to a depth of about 3 inches, water by using a sprinkling can, and then watch the temperature of the bed carefully until the potatees have formed an abundance of sprouts. sunuy mee JANUARY, 1909. | TEMPERATURE OL THE PLANT BEp. As noted above, the temperature of the plant bed should be about 80” or 85° F. at the time the seed is bedded, and should gradually fall until it remains stationary at 58° or 60° Ff. at the end of six weeks, or before planting-out time. A thermometer should be kept plunged in the soilof the bed and the temper- ature noted every day for the first ten days or two weeks. If the manure hotbed is not located ina well-drained situation there is danger of soil water getting in with the manure and either destroying the heat altogether or start- ing asecond fermentation which will cause the temperature to run too high and injure the potatoes. The air tem- perature beneath the sash or other covering should run between 60° and 80° F., and during bright days it must be controlled by ventilation. As the time for planting in the field or garden draws near, the plants should be given more exposure to harden them _ to outdoor conditions. MOISTURE REQUIREMENTS OF THE PLANT BED. The amount of water required by the plant bed will depend somewhat upon the method of heating employed. With a steam-heated or furnace-heated bed more watering will be necessary than if the ordinary manure hotbed is used. The watering given when the potatoes are bedded will generally be sutficient to last for several days, but after the plants begin to form leaves and the cover is left off during the greater part of the day, watering will be necessary every day. The water should never be poured on in a solid stream, but by means of a sprinkling can or a rose, or nozzle, on the end of a hose. Where very large plant beds are employed it will be necessary to keep some one in almost constant attendance to care for the watering, heating, and ventilation. The success of the crop depends largely upon the character of the plants, and proper management of the plant bed is essential to the production of the right kinds of plants. “DRAWING” THE SETS. ‘““ As a general rulesweet potato plants are set in the field shortly after a rain. In order to avoid delay in planting, the hands should begin to get out the sets as soonas the rain ceases falling and place them iu crates or baskets ready for transportation to the field. The sets are not all produced at once, and only those that have formed good roots are ‘drawn,’ the others being left until later. In‘ drawing’ the sets the seed potato is held down with the 45 Edible Products, one hand while the plants are removed with the thumb and finger of the other hand. It often happens that five or six plants will cling together at the base, and these should be separated in order to avoid loss of timein the field. Where plants are to be set with a transplanting machine it is essential that they should be in the best possible shape in order that they may be handled rapidly by the boys who feed the plants into the machine. The roots should all be kept in one direction, and if the tops are long orirregular they may be trimmed off even by means of a knife.” While ‘‘ drawing” the sets it is a good plan to have at hand a large pail or a tub containing water to which there has been added a quantity of clay and cow manure which has been stirred until it forms a thin slime. As the plants are pulled from the bed they are taken in small bunches and their roots dipped into this mixture. This process, termed *“puddling,” covers the roots with a coating which not only prevents their becoming dry in handling but ensures a direct contact with the soil when they are planted in the field or garden. After removing the sets that are ready, the bed should be watered to settle the soil where it has become disturbed and then left for the younger plants to develop. PACKING PLANTS FOR SHIPMENT. In preparing sweet potato plants for shipment or for sale, they are ‘“‘ drawn” from the bed and tied in bunches of 100 each with soft string. Sweet potato plants will not withstand excessive moisture and should always be packed while the tops aredry. A little damp moss or paper may be placed in the crate or basket and the roots bedded in it, but the tops should remain dry and have free ventilation. Ifthe roots of sweet potato plants are carefully puddled without the mixture coming in contact with the tops, they will keep in good condition for a week or ten days. PREPARATION OF LAND FOR SWEET POTATOES. The character of soil devoted to sweet potato culture is generally quite easy to prepare. In preparing land for plant- ing sweet potatoes the plowing and fitting are practically the same as for corn. It should be borne in mind, however, that the work necessary for thorough preparation will be well repaid by the increased ease in handling the crop later. It is always desirable that a crop like sweet potatoes be grown as a part of‘the regular farm rotation. In the northern portion of the sweet- Hdible Products. potato-growing area the crop will occupy the land the entire growing seasons, and a three or four year rotation should be practised. Where the climate will permit, a crop of early snap beans, peas, or cabbage may precede the sweet pota- toes, but in many case the land should not be planted to sweet potatoes oftener than onee every three vears. A good rotation is to devote the land to corn one year. sowing crimson clover in the alleys between the rows at the time the corn is given the last cultivation. During the following spring the crimson clover should be turned under and sweet potatoes planted; then in the autumn, after the potatoes are harvested, the land may be plowed, fitted, and sown to rye or winter oats with plenty of grassseed. In this way, crop of grain may be obtained during the time that the grass is becoming established. Allow the land to remain in grass one or two years and then repeat the rotation. Where cornis followed by sweet potatoes in the rotation, stable manure should be applied while fitting the land for the corn, and commercial fertlizers should be applied with the sweet potato orop. As previously mentioned, the depth of plowing.has considerable influence upon the character of the product. The usual depth of plowing in preparing land for corn will prove satisfactory for sweet potatoes. The tact that sweet potatoes are not planted in the field until quite late in the spring makes it possible for the grower to select a time when con- ditions are favourable for the prepara- tion of the land. Plowing may be defer- red until the soil has become sufficiently dry to break up fine and mellow. It is important that the land should be har- rowed within a few hours after plowing ; further fitting may be deferred until later, and if the soil is inclined to be lumpy the work of pulverizing may best be done shortly after a shower and while the lumps are mellow. When the pri- mary work of preparation is finished, the soil should be mellow to a depth of 6 or 7 inches and the surface smooth and even. Subsequent handling of the soil preparatory to_ planting will depend upon whether ridge or level culture is to be followed. APPLICATION OF FERTILIZERS. " For the general good of the land com- mercial fertilizers should be applied broadcast, but the majority of farmers feel that they cannot afford to do this and that the quantity that they are able to apply ‘will give greater returns when placed in therow. Thisisa matter for the decision of each grower and will [ JANUARY, 1909; depend greatly upon the capacity of the soil under consideration for retaining fertilizers from year to year. PREPARATION FOR PLANTING. _ After plowing and fitting the land it is generally allowed to lie several days before being put up in shape for planting. If level culture is to be practised, the only thing necessary will be to run the harrow over the _ soil once and then mark in both directions at the desired distances for planting. The marking is generally done with either a one-horse plow, a_ flat-soled marker. or a disk marker. The disk marker is well adapted to this work, as it throws up a slight ridge which fur- nishes fresh earth in which to plant. Some growers who practise level culture mark the ground with a small one-horse plow and throw up a slight ridge upon which to plant; behind the plow a roller is used to compress this ridge to a low, flat elevation. Where the more universal ridge method of planting is employed the soil is thrown up by means of a turning plow or a disk machine. The ridges should be made at least one week or before planting, in order that the soil may become settled and compact. The majority of sweet- potato growers make the ridges when- ever the land is in good condition to work and then either roll or drag the tops just ahead of the planters. By using a roller the ridges at one operation can be rolled and marked the proper distances for planting. A drag suitable for smoothing the tops of the ridges can be easily constructed by cleating together three pieces of 2 by 4 inch scantling. SETTING THE PLANTS. The success of the crop depends largely upon the way in which the plants start after being removed from the bed and set in the field or garden. Practical growers always plan to set the plants during a ‘“‘season” or period when the conditions are suitable to a quick start into growth, either just before a rain or as soon afterward as the soil can be worked. The method of setting will de- pend entirely upon local conditions and the acreage to be grown, the essential features, however, being to get the roots in contact with moist earth and the soil firmly pressed about the plants. The use of water around the roots of the plants is desirable under most cir- cumstances, as it not only moistens the soil but assists in settling it about the roots. A large quantity of water is not necessary, one-half pint to each plant being generally considered sufficient. sien) JANUARY, 1909.! DISTANCES TO PLANT. Where level culture is practised, the plants are set from 24 to 30 inches apart in each direction. On the eastern shore of Virginia the greater portion of the crop is planted 24 inches apart each way, requiring about 11,000 plants to an acre. By planting 30 inches apart each way, only about 7,000 plants are required to set one acre. Where the crop is grown on ridges it is customary to have the ridges from 36 to 42 inches apart from centre to centre and to place the plants 14 to 18 inches apart in the row. By this method an acre will require from 8,000 to 12,500 plants. An acre of good sweet potato land will readily support 9,000 to 11,000 plants, and the number most commonly planted by the several methods will fall within these figures, When planting for level culture the location of the plants will be indicated by cross marks, but for planting upon ridges itis necessary to provide some means of indicating the distances. This may be accomplished in severel ways, but a roller hafing cleats nailed at equal distances around its surface is desirable and serves the purpose of both rolling and marking the ridges. Another device is contructed along lines similar to those of the ordinary wheelbarrow, pegs being placed upon the rim of the wheel to mark the planting distances. In using the wheelbarrow marker it is simply pushed along the top of the ridge. Another device of this class is con- structed by placing three or four wheels upon along axle and drawing it witha horse, the wheels being so arranged that they can be set at any point on the axle to provide for change in width of row. A very cheap and efficient can marker be constructed of 1 by 38 inch laths. This marker can be used to indicate planting distances along one row, or by dragging it across the ridges the entire field can be marked before beginning to plant. The machine transplanters are provided with a spacing device which indicates the distance between plants; also with a row marker to show the location of the next row. SETTING By HAND. Where a few hundred plants are to be grown for home use orif only an acre or two are to be planted, the hand method of planting will answer every requirement. A trowel or a dibble is used for opening the soil to receive the plant, and the earth is closed about the roots by a second thrust with the imple- ment, or the heel of the shoe is used _ to press the earth about the plant. For Edible Products. hand planting, the plants are dropped ahead of the ‘‘dibblers” by boys and girls. Seven thousand to ten thousand plants, or an acre, is an excellent day’s work fora planter when everything is in good condition. Where a few hundred plants are set in the garden it is always desirable to water them before closing the earth about the plant. PLANTING WITH TONGS. Setting by hand is at best a back-break- ing process, and numerous devices have been invented to save the bending of the body in hand planting. One of the simplest of these is a pair of wooden tongs with which the plant can be caught by the root and thrust intothe soil. The plants are either dropped ahead or carried in a small basket strapped to the waist of the operator. The tongs are provided with a spring to throw the jaws apart, and are held in one hand while the plants are inserted with the other hand. In case the plants are dropped ahead, the root portion is grasped between the points of the tongs without the use of the hand. An implement, known as a shovel, which is sometimes used in conjunction with the tongs, consists of a piece of lath sharpened toa flat point. This is used toopen a hole in the soil ready for the plant. In using the tongs and shovel, the plants are dropped as for hand planting. The person doing the setting carries the tongs in the left hand and the shovel in the right. The plants are picked up by means of the tongs, while a hole is made by inserting the shovel in the soil at the point where the plant is to be set. The plant is then inserted and the earth closed about it either by a second thrust of the shovel or by the foot of the operator. A man who is expert in the use of these home- made tools can set plants quite rapidly without bending the body sufficiently for the work to become tiresome. A tool that is sometimes employed where vine cuttings are planted is a long dibble ora cane havinga notch covered with cloth or leather in the lowerend. The droppers lay the cuttings across the row atthe proper distances and the planters place the notch over the middle of the cutting and force it jato the soil with both ends protruding. SETTING WITH MACHINES. Where a large acreage is grown, the work of setting the plants in the field is greatly facilitated by the use of trans- planting machines, of which there are several makes upon the market. The essential features of these machines are a device to opena small furrow, a tank Edible Products. 46 for the supply of water, and disks or blades for closing the soil about the plants. Withwa transplanting machine itis not necessary to wait for a ‘‘season.” as the machine automatically throws a small quantity of water around the roots of each plant as it is being set. In operating these machines it is necessary to have a steady team and two active boys who are trained to drop the plants at proper intervals, as indicated by a spacer on the machine. Under reason- ably favorable conditions, a machine will plant from 38 to4 acres a day. In addition to being labor savers, these machines do the work better and more ery, than itis ordinarily done by aand. The plants can be set without the use of water, but the results are more satis- factory where the water is used. A number of our most successful growers use water when setting after a rain, claiming that the water has the effect of settling the soil firmly about the roots of the plants and that they start into growth much more quickly. Where the full amount of water is used it will be necessary to provide aman and team to hold the water to the machine, but by this method plants may be set during dry weather without the loss of more than one plant out ot every one hundred. The majority of the transplanting machines are designed for planting either on the tops of ridges or on the level. The cost of setting an acre with one of these machines, using water, should be figured on the basis of two teams with drivers and two boys for a period of three or three and one-half hours. If water is not used there will bea saving of at least one team and driver; also the time required for filling the tank on the machine. CULTIVATION OF SWEET POTATORS. The methods of handling a crop of sweet potatoes do not differ materially from those employed with ordinary farm and garden crops. Within a few days after planting, a sweep or onehorse plow should be run in the alleys to break out the strip of earth left in ridging, The loose earth in the alleys should be worked toward the rows until a broad, flat ridge is formed upon which a small-tooth cultivator can be: run quite close to the plant. After each rain or irrigation the soil should receive a shallow cultivation, and during dry weather frequent’ cultivations are necessary in order to retain mois- ture. About two hand hoeings are generally necessary in order to keep the rows free from weeds and the soil loose [JANUARY, 1909. around the plants. As hand labour is ex- pensive, it should be the aim to perform the greater part of the work by means of horse tools. Where sweet potatoes are planted in check rows and worked in both directions the hand work re- quired will be reduced to a minimum, but a certain amount of hoeing is always necessary. When the vines begin to interfere with further cultivation the crop may be “laid by,” 7.e., given a final working in which the soilis drawn well up over the ridges and the vines then allowed to take full possession of the land. Todo this it is often necessary to turn the vines first to one side of the row and then to the other by means of a stick or a wooden rake. After “laying by,” very little attention is required until time for harvesting the crop. ; Toots ADAPTED TO SWEET POTATO CULTIVATION. Aside from planting and harvesting, the work of caring for a crop of sweet potatoes can be done almost entirely by the use of ordinary fapm and garden tools. A two-horse riding cultivator is desirable for the general cultivation, and one having disks instead of hoes will serve for throwing the soil toward the rows. For the work of “ laying by.” a single-row celery hiller is suitable or a one-horse sweep-stock can be fitted with sloping boards and used for this purpose. Many growers use a small one-horse tur- ning plow for the final cultivation, going twice in each alley and working the soil toward the plants. (To be continued.) . CITRATE OF LIME AND CONCEN- TRATED LIME JUICE, Dr. Watts, Government Chemist and Superintendent of Agriculture for the Leeward Islands, briefly reviewed the position of the Lime Juice Industries of Dominica and Montserrat :— During the past year little additional nformation had been obtained and reference should be made to the article prepared for the last West Indian Agricultural Conference and published in the West Indian Bulletin, Vol. VIII., pp. 167-9. Concentrated juice prepared from lime juice that has been carefully strained and then settled, after distilla- tion, has obtained a special market for direct use in various arts and manu- factures in the place of crystallized citric acid. It commands relatively higher ' JANUARY, 1909.] 47 prices than ordinary concentrated juice, and therefore every effort should be made by planters to ship a high-class product. The use of centrifugals in drying citrate had given very good results. Centrifugal-dried citrate contained much less water than the ordinary pressed product, and was in a better physical condition. Samples of different types of citrate now exhibited show clearly the better condition of the centrifugal dried citrate, and would indicate when citrate of ‘lime is made on a large scale the use of the centrifugal instead of the ordinary process is to be recom- mended. Mr. Joseph Jones, Curator of the Botanic Station, Dominica, gave the following information in respect to the progress made in the manufacture of citrate of lime in Dominica during the past year :— During 1906, the year in which citrate of lime was first exported from Dominica, 728 ewt. of this product was exported, During 1907, 2,388 cwt. of citrate of lime was shipped, showing an increase over the export of 1906 of 1,660 cwt., a very satisfactory advance. Up to the present time only one firm has been engaged in making this product, but it is probable that another estate may shortly commence its manufacture. The great drawback in making citrate in Dominica at present is the cost of drying the product. What is required is efficient machinery for cheaply and quickly drying the citrate withont loss of acid. When such an apparatus can be obtained without too great a cost, the chief obstacle in the making of citrate of lime by estates will have been removed, Should such machinery be of too costly a character for estates making 80 to 100 hogsheads of concentrated juice to instal, then we may expect to see the development of factories at suitable points in the several districts for the purchase of lime juice from adjoining estates to be made into citrate of lime. Information as to the cultivation of the lime and to the manufacture of its products has been prepared in co-oper- ation with the scientific officers on the staff of the Imperial Department of Agriculture, and will shortly be issued in pamphlet form.*— West Indian Bul- letin, Vol. IX., No. 2 * A.B.C. of Limo Cultivation, Pamphlet No, 53, issued. in March, 1908.—Hd, W./,B, Hdible Products. THE IMPROVEMENT OF CACAO PLANTING IN THE WEST INDIKS. By J. H: HART, F.L.S., Superintendent, Royal Botanic Gard ens, Trinidad. Cacao estates in Trinidad are largely planted on what is known as the con- tract system. Under this system the proprietor gives out certain areas toa contractor, and after the land has been cleared at the expense of the owner, the contractor enters into possession for usually about five years. During this time the contractor drains the land and grows certain crops for his own benefit, and at the same time plants cacao as laid down by contract. When the lands are taken over by the owner from the contractor, 1s. tols. 3d. is paid for each full bearing tree, half that price for each half tree, and a quarter for each quarter tree. The general adoption of this system appears to depend upon the fact that under it less immediate expenditure of capital is incurred, and. the planter when he has paid for the trees at the end of the term, should immediately obtain some return for his money, for many of the trees should be commencing to bear, Briefly, the proprietor gives the land for five years for the cultivation of food products, with some few restric- tions, in return for the labour expended in planting and rearing the cacao trees with addition of a bonus per tree at the end of the term. In Tobago, the contract system is not generally adopted, and some estates are formed by the owners, There is but little difference to be noticed between aun estate planted under contract, and one planted by an owner. The actual method of planting under both systems is identical; the same class of tree is planted, the same shade is used, and the same technic is adopted in both cases. The methods pursued in other places vary somewhat from those described, but are in principal fairly identical. There is no reasonable doubt that although the contract system may have its advantage as affording a cheap means of establishing a plantation, it is not one which provides for the scientific treatment of ‘the cacao tree, as it is based entirely upon growth from seed. The cacao tree grown from seed varies in vigour and _ productiveness, and in size, colour, and flavour of its produce. The seed of red pods may produce trees bearing yellow ones, and those from yellow may produce trees possessing red Edible Products. ones. In the seed itself there is great variation in size, colour, flavour, and number of seeds to a pod, These variations, left to themselves, are (following the accepted doctrines of our best botanists) sure to tend toward deterioration; but properly guided they afford the means of not only maintaining a standard but of improving. that standard in any desired direction. At the present time Trinidad cacao is an interminable mixture of various types near to, and far from, the original strains. The better types prevail where a preponderance of the better kinds were first planted, aud the poorer types in those districts where numbers of in- ferior strains are present. It would appear that there is little cacao true to the original types of old authors, and although the various strains can be recognized, it is much more easy to notice the variation that has occurred, even during the last two decades. Trinidad Criollo can still be recognized generally, but the bottle neck of that variety is now to be seen plainly marked in varieties where the Forastero strain predominates. The Venezuelan Criollo may be seen ap- parently true in form and colour with the accepted type, but on examination shows that the plants may have coloured instead of white beans, I suggested in 1897, thatit was urgently necessary when raising from seed, to be extremely careful in selecting from the very best trees, but 1am now quite con- vinced that. this method, while being better than no selection at all, is quite in- sufficient to secure the highest class of produce, and that vegetative production by budding or grafting must be adopted if cacao is to be improved along scienti- fic lines. In 1897, it was not certain ‘that budding or grafting was practi- cable with cacao, but it has since been proved that they may easily be per- formed. Recently I prepared an article on cacao improvement that was pub- lished in the Trinidad Bulletin, Vol. VII., p. 183. In this was described in detail the method necessary for the improvement of plantations. The principle points are (1) the entire abandonment of propagation from seed except for the purpose of raising new and improved varieties, (2) improvement by the aid of hybridization or seminal variation, (8) the selection of standard varieties trom present fields showing desired characters in order to propagate from them by grafting or budding, and (4) the characters to be used in making 48 [JANUARY, 1909. the selection should be high vitality, good bearing qualities, good habit and form, and a high quality of produce. At the Conference held at Trinidad in 1905, I presented a paper on the special qualities of plants. In it I presented arguments to show that special qualities are inherent in each and every indivi- dual plant, which remain constant through its life and may be propagated indefinitely for centuries ; and 1am more than ever confident that if these views are brought into practice in the working economy of cacao estates, a very great improvement in the quantity and quality of the produce obtained would rapidly follow. One treein the Botan- nical Department, Trinidad, produced in 1907, 15 lb. 9 oz. of marketable cacao, and it would appear desirable that such a tree should be among the selected varieties to be reproduced by vegetative reproduction. In cacao plantations there are trees of a high class, and also many of an inferior type. The latter, being as a rule ot greater vegetative vigour, tend to domi- nate, and gradually may push out the better strains. In the following gener- ations, when again reproduced by seed, deterioration necessarily occurs and a large number of interbred varieties is produced. It is satisfactory, however, to note that not a few planters are alive to this danger of deterioration in quality, and have imported of the best strains from the mainland of South America. Even these show considerable variation. These importations, nevertheless, are of superior quality, and they must have an effect, though a limited one, inimproving the standard quality of Trinidad cacao, The improvement can ouly be a tran- sient one, as the inferior kinds, being the more vigorous, and inthe majority, will again, in time, dominate the better qualities. lf, however, selections are made of the most distinct forms, and these are propagated solely by vegeta- tive reproduction, the improvement would most assuredly be a permanent one, and when once standard and selected kinds are propagated by this method alone, and not by seed, deteri- oration would cease, and no change in the quality of produce could occur, except that induced by unfavourable weather, accidents during curing, or by unfavourable situations. Trinidad cacao has obtained a name for certain good qualities, but manu- facturers cannot use Trinidad cacao alone. They require other and often higher-priced qualities to mix with it JANUARY, 1909.} to obtain the eecessary blends. The average grower may be content with his returns, but why should not West Indies, with her excellent facilities for growing cacao, be possesed of and grow all the various kinds needed by the manufacturer to make the required blends, for the production of high-class chocolate and cocoa? Or why should not the West Indies possess sufficient of each kind to be able to start successfully the local manufacture of various cacao products? . It cannot be done to-day, because several of the special qualities necessary for making the flavours now recognized, and demanded, are absent from West Indian cultivation. Therefore it is important to encourage the introduc- tion of plants of all the foreign cacaos which are necessary for the preparation of the manufacturers’ blends. They should be kept pure by. reproduction solely by budding and grafting. The West Indies would then be able to put into the hands of the manufacturer all that he needs in the way of qualities. It may be said that prices of Trinidad cacao are at present satisfactory. But will they always be so? Every endea- vour should be made to take advan- tage of every improvement to raise the quality of cacao, as in years of bad prices it is well known that certain brands sell at higher rates than others, because the manufacturers require them, and that in general a pure brand or well-known mark is accepted at higher prices than ordinary mixed strains. Thereis nothing to be said against a grower who wishes and prefers to grow alow-grade cacao, but it is fairly clear that his returns will not equal those obtained by the growers of high-class produce, and even these will fetch more if kept pure by vegeta- tive reproduction, as they can be better relied on for strength and evenness of quality. The question of the production of high- class cacao of the various market quali- ties appears to be a very desirable one; and should be the aim of cultivators who wish to attain to a high standard. DISCUSSION. THE PRESIDENT: I am glad to take advantage of this opportunity of ex- pressing the general fesling in the West Indies in regard to Mr. Hart’s long and useful career in connection with agriculture. Mr. Hart spent the earlier years in Jamaica where he was connected with my Department there. He has since been in Trinidad, and there can be no doubt whatever as regards the earn estness and thoroughness with which he 7 49 Hdible Products. has carried on his work. Iam very glad of this opportunity of putting that on record, and also of thanking him for this very useful, and, I think, very suggestive paper which he has presented before the Conference to-day.— West Indian Bul- letm, Vol. IX., No. 2, THE CHARACTERS OF CRIOLLO CACAO. By J. H. HART, F.LS., Superintendent, Royal Botanic Gardens, Trinidad. Criollo cacao, as represented by the specimens exhibited, may be divided into three sections: (1) 'Trinidad Criollo, @) Venezuelan Criollo, and (8) Nicaraguan Jriollo, Trinidad Criollo is supposed to be indigenous to Trinidad. The specimens exhibited are the produce of trees grown from pods selected by G. Kernaham, Esqr., taken from original forest in the district sf Manzanilla, Trinidad. Some of the pods were yellow, and some red, It has been found that seeds from yellow pods are able to produce trees bearing red pods, while those from the red pods often produce trees bearing yellow pods. The generally light colour of the beans and their form are characteristic of the variety, while the bottle-necked appear- ance of the pods is a leading feature by which they may be recognized. This type of Criollo cacao is not quite as vigorous as are the Forastero and Calabacillo types, and though a fairly good bearer, does not yield as well as those kinds. Venezuelan Criollo differs in form from that of Trinidad, as the stalk end is blunt and_ rounded instead of being bottle-necked. The beans are larger in size than those of Trinidad Criollo, and differ somewhat in form: but like the Trinidad kind, the beans when cut show a white or nearly colourless interior. Specimens of this kind of Criollo cacao grown in Trinidad havebeen produced from seed obtained from one of the best Venezuelan estates, The produce shows considerable variation both in outside colour and form of the pods, as well as in the colour of the beans. They are not prolific bearers, but the quality of the produce is of the highest class, and estates possessing this strain can obtain high prices. This kind is also known under various other names such as Caracas, Borborata, etc., etc, Edible Products. 5 The Nicaraguan Criollo differs some- what from the Venezuelan in form of ods. The size of the bean is also much arger. The colour of the beanis white and not so often shaded with colour as the Venezuelan, and Trinidad Criollos. The pods are rather more pointed in form than the Venezuelan, but much resemble them in other respects. The beans produced by this kind are probably the largest of any known valiety of Theobroma cacao, and com- pare very closely with those produced by Theobroma pentagona, a species with which it may have become hybridized in Nicaragua. The bean of the Nicara- guan Criollo, like that of Theobroma pentagona, is, for its size, light in weight. It possesses a flavour of very high standard and takes_much less time to cure than ordinary Trinidad cacao. Propagated by grafting and kept pure, this cacao promises to become a valuable acquisition to West Indian plantations. GENERAL REMARKS. Grown as seedlings, these three varieties are not heavy bearers and as crop producers cannot be compared to the stronger growing strains of Foras- tero and some other varieties. All three kinds possess valuable characters, and it is highly probable that when grafted on the stronger stocks, their yield would be materially increased, and they would become a valuable asset to the West Indian cacao. planter.—West Indian Bulletin, Vol. [X., No. 2. ENSILAGE AND HOW TO MAKE IT The preservation of fodder in the shape of ensilage with all its succulent prices retained, has been thoroughly tested by so many practical men in other countries that its value as a factor in economical stock-keeping has been proved beyond question, In Ceylon, so far, the subject seems to be little under- stood and, as far as I learn, nothing practical has been done. To_ properly appreciate the practical details of the process it is necessary to understand at least the outlines of the theory. We aim at the preservation of green or succulent fodder, and the more we can diminish or prevent the changes which such substances naturally undergo when cut or gathered into heaps the better will be the quality of our silage. To do this effectively we have to learn what these changes are, and how they are brought about. Weknow that when green fodder is cut and placed in a heap it soon begins to heat and undergo changes. This rise of temperature and [JANUARY, 1909, these changes are due to oxidation and the presence of minute living organisms, termed bacteria. These bacteria, fer- ments, or microbes are everywhere distributed in the atmosphere, endless in variety and infinite in number, Pasteur has shown that these ferments or microbes require air in their first generations or when their work begins, but that afterwards they can go on multiplying generation after generation without air—that in fact fermentation is directly the result of their breathing the combined oxygen of certain organic substances, such for example of sugar in the absence of free Oxygen. When the green herbage is placed in the silo or stack IMMENSE NUMBERS OF THESE MICROBES will be in contact with it or on it, and in the free air in the spaces through- out the mass. In the presence of this free air they begin their multiplication and work, but as we have seen the work is continued and becomes more manifest when the free oxygen among the contents of the silo or stack has been exhausted, unless in the mean- time the germs have by a rise of temperature been killed. It has been found that a temperature of 120 deg. Fahr, or thereabouts is sufficient to kill these ferments, and it is desirable there- fore that the temperature of every silo or stack should exceed that range. If it does not the organisms live on and work on, and through their vital fune- tions change valuable food stuffs and produce acetic acid, the acid of vinegar, buric acid, the acid which gives the rancid flavour to butter, and lactic acid or the acid of sour milk, The feeding value of the silage is consequently diminished in proportion to the degree of this fermentation. When the fer- mentation has been allowed to continue in this manner, sour ensilage is the result, and it has accordingly less fatten- ing value than sweet silage although it is valuable to the dairy farmer for milk production. But there is another cause of change in the cells of the ‘plants ensilaged, and it is that which is believed to bring abdut the rise of temperature. When the crop has been cut and has begun to wilt, the cells would appear to continue living, and that for some time until through desica- tion ov otherwise the contents cease activity. While thus living their vital functions are reversed, instead of absorb- ing carbonic acid gas and giving out oxygen—the normal function of plants —they now absorb oxygen and give off carbonic acid. This is known as intercellular oxidation, and when the herbage has been carted to the silo oe hem oa ” ; JANUARY, 1909.] or stack shortly after being cut, and while the cells are still living, this oxidation is the cause of the rise of temperature. By means of it also the starchy substances of the cells are changed into sugar, and the sweet flavour of sweet ensilage is the result. When the cells continue living and oxidation continues alcohol is formed and the feeding value is accordingly diminished. But when the heat evolved by this process of oxidation has raised the temperatureto 122° Fahr. the vitality of the cells is destroyed, and further oxidation accordingly ceases. There are TWO WAYS OF STORING SILAGE, in the stack and pit. The former has the advantage of its cheapness, but experience has shown that it is far more difficult to handle and that the results are not so good, while the waste is great and that it requires pressure. In the pit or silo it is much easeir to regulate the temperature, and there is far less waste while no pressure at all is necessary. There are also two kinds of ensilage made, the sweet and the sour, the former for fattening and the latter for milk production. For the making of silage the crop must be cut when there is the most sap at maturity. This is best ascertained by experience which agrees with the average of 75 per cent. of moisture. A practice adopted by many practical men is to take a quantity of the grassin the hands and twist it like arope so that if moisture drops from it freely it is time for cut- ting: Ifthecrop is not caught at the right period there is aloss of nutritive value in the silage in proportion to the delay, for at this stage the assimilative process of the plant has practically ceased, and its energies are devoted to the transference of the nutritive mate- rial from the leaves and stems to the seed. If cut too early and crop has too much moisture it will be difficult to get the temperature to rise sufficiently high. The result would be as explained above, that the fermenting germs will not be killed and in conjunction with oxidation ane nutritive value is greatly lessened. MAKING SILAGE IN THE STACK, the spot chosen must be One most con- venient for stock to feed. The stack should be as large and square as possible otherwise there is much waste. Rapid work for sour ensilage and slow tor sweet, temperature from 80 to 90 degrees for the former and 125 to 140 degrees Fahr. for the latter. Ifsour ensilage is being made and the temperature is found to rise above 90 degrees the stack must be stamped down until the tem- a) | Edible Products. perature is lowered. To test the tem- perature from time to time a simple con- trivance can be made. Ten feet length of gas-piping with a steel point welded on to it is driven into the stuff to any depth and a small thermometer let down by means of a string. If the tem- perature is allowed to go too high the silage becomes dark coloured, dry and almost charred, but this contingency can always be prevented by adding further green stuff, or, if the stack is finished, putting on weights. While building the stack or filling the silo great care should be exercised to have the distribution even, not lumpy, and to have the stuff wel trampled round the sides. If this is not done the air gets in round the walls, and here and there well into the mass, and destruc- tion follows accordingly. The bacteria present originally and the cells of the plants ensilaged will have been killed by the high temperature, so that if the air be allowed ready access thereafter a fresh infection of microbes and fungi is admitted, and decomposition more or less results. Stacked silage has many apparent attractions for a_ beginner because of its supposed cheapness. Ex- perience has proved that THE PIT IS BETTER AND MORE ECO- NOMICAL. The waste in astack is very great. As a rule the surface of a stack to the depth of about a foot or more is rotted and completely spoiled. This waste with the annual cost of weighting down the stack and then removing the weights, and the considerable loss that comes subse- quently from the exposed condition of the stack are all which more than compensate for the supposed cheapness in the first instance of the stack itself. For weighting stacks all sorts of mate- rial can be used—stones, bags of earth, kerosine tins filled with earth or con- crete, logs of timber, etc., aiming at about 200 lbs, per square yard. There are also many mechanical devices con- trived and used. If ensilage is to be made in silos or pits the construction of them should be on the highest land available as there is less chance of soak. age, a pit 15 by 15 feet will hold 50 tons of silage. The pit must be bricked and roofed over. The same principles apply tomaking as in the case of stack, but of course in an airtight silo it is much easier to regulate temperature and. thus either to make sour or sweet as desired. It is much the best process to chaff the stuff into the silo especially heavy stuff like maize. Short grass needs no chaffing. I made pit silage for some years with maize and other crops fe Edible Products. with the very best of results. With a pit no pressure is necessary. Spread the stuff evenly, taking the temperature now and again. If temperature rises cramp it down all over specially all round the edges, and when the crop is all in and the temperature is bound to keep right, cover with some straw, and in three months the result will be first class ensilage. CROPS FOR SILAGE. Any vegetation that stock will eat in its natural state will make good ensilage, and it will be much improved by the operation. It is said that cattle assimilate silage better than they do any other food, the reason being that the change effected in the silo is nearly or quite that which is brought about in the first stomach of the cud-chewing animal. Maize makes a specially good silage and can be highly recommended. As regards other material, experience cau only show what other Ceylon crops makes the best silage. In conclusion I may sum up the whole process in the following facts :— (1). Appropriate crops combining suc- culence and maturity. (2) To harvest when the crop has about 75 per cent. of moisture in its com- position. (8). The staking, or chaffing and filling of the silo, to proceed sv that the temperature of the material reaches 80 degrees and does not exceed 90 degrees for sour, while 125 to 140 degrees Fahr. for sweet. 52 "a rin ee -] [JANUARY, 1909 (4).

Anything which can be done to encour- age the sugar industry in India should be welcome, for its progress is slow and the enormous imports from Java show no sign of falling off. In the Indian Trade Journal particulars are given of a process for utilizing the waste products ° of manufacture, the residue of the cane after it has passed through the mill. At present this is useless except when dried for fuel, but it is said to have qualities which make it valuable for paper manufacturers. A Trinidad sugar planter has invented a process by which the crushed canes are converted into paper pulp, and he is now working sugar and paper mills in combination. The new pulp is worth £5 per ton, and as there is a general shortage of wood fibre for paper-making the new product commands a good sale. It issuggested that experiments should be tried in India whereby the waste products of our sugar-mills could be utilised in the manner described, Perhaps the Agri- cultural Department may take up the matter and obtain particulars of the Trinidad process with a view to its adoption in India.—Indian A griculturist, Vol. XXXIII, No. 9.) JANUARY, 1909.] 53 PLANT SANITATION. THEORY OF THE PARASITIC CONTROL OF INSECT PESTS, All who have recently discussed the question of the possibility of controlling insect pests by the use of parasitic or predaceous insects or by fungous or bacterial diseases, have failed to consider the subject from a very important point of view. The conditions determining the life or death of insects are much more com- plicated than is usually appreciated, and the individual factors in the problem are far from independent. The correct estimation of this interdependence of the causes of death in insects is of vital importancein this connection. The efficiency of each factor is so influenced by the efficiency of the others that the elimination of one cause of death or the addition of an entirely new natural enemy will usually have but a slight poet upon the rate of survival or none at all. The reproductive powers of most or- ganic beings are very great. Were not all creatures liable to die prema- turely, that is, before they repro- duced themselves, reproduction would of necessity have been limited to two off- spring from each pair. Whenever re- production is at a more rapid rate itisa prima facie evidence that the chance cf premature destruction requires it and the greater the reproductive power the higher this normal death rate. Were conditions otherwise, rapid extinction or enormous increase would result, The fact that species maintain themselves for ages with the rate between the birth rate and that of premature death not varying anappreciated fraction of a per cent. is very evident. This balance between birth and death- rates ismuch greater than the numerical stability. For instance, in the case of a species increasing a hundred fold in a generation, an average disturbance of only a hundredth part of a per cent. in this ratio—.e,, if onthe average one more individual inten thousand should come to maturity—this would result in nearly tripling the numbers of individuals within a, hundred generations, and one tenth of one per cent. augmentation— e.g., if one more in a thousand should survive—would be an increase in num- bers amounting in the same period to nearly fourteen thousand fold. DISTURBING, CONTRIBUTING AND EFFECTIVE HACTORS. The various causes of death may be classed into two groups; first, those that des troy all insects in a certain con- dition or position, irrespective of the numbers present (for instance, frost, which might kill the same proportion whether there was but one to the acre or a hundred thousand); and second, those that are more and more efficient as the numbers increase. This is true in general of predaceous and parasitic insects and of diseases. Causes of death of first class will aid in maintaining the balance in an insect tothe extent they are uniform in their action, the regular- ly recurring winter, for instance; but are usually erratic and_ disturbing rather than balancing. Those of the second category, however, iall tend towards balance and their efficiency is attested by the approximate balance maintained in nature. Probably in all cases numerous parasites “and pre- dators and other factors of this same class contribute to form the controlling environment of an injurious species, and each factor has a different potenti- ality. Those of the second category can be further subdivided into two classes, the contributory and the effective. In the former class, the efficiency increases with the increase of the host, but not in a sufficient ratio to ever overtake it. Thus with the host at one hundred per acre it may destroy one third. at two hundred four ninths, at four hundred thirteen twenty-sevenths, etc., never reaching fifty per cent. Any series that does not ultimately pass the percentage of normal death rate is incapable of itself diminishing the numbers of its host. Its only effect is inslowing down the rate of increase until some effective factor becomes operative or until a dis- turbing factor like frost produces a general destruction. The effective class of factors is that in which the ratio finally reaches one hundred percent, Thus with the host at one hundred per acre it may |destroy say one half, at two hundred three quarters, at four hundred, seven eighths, ete.; finally reaching a fraction so large that only those survive that are necessary to maintain the species. Every factor of this class has its particular point of balance, One may overtake the host at two hundred per acre and another only at two million Plant Sanitation. per acre, but both be finally efficient, Toamember of this class of checking factors, Mr. Elwood Cooper, the former Horticultural Commissioner of Cali- fornia, would apply the term ‘“ the true parasite,” and those alone he would consider worthy of importation. To determine at any time the status of an insect we should have to know the percentage of efficiency of each factor under the existing numerical promi- nence of the host, and in order to prog- nosticate the future we should need to know the ratio of increased or decreased efficiency of each under the changed numbers of the host. None of these factors can ever be determined with any greas degree of accuracy because they are each involved in as complicated a system of inter-rela- tions and in many cases the efficiency ot a check against any one insect is profoundly influenced by the ups and downs of numerous other insects that serve as alternate hosts. The complication of the subject indeed is so great that accuracy even of obser- vation will beimpossible, but the failure to reckon with all the factors of the problem will make conclusions of little significance. The inter-relation of factors may be of the most complicated nature; for in- stance, a parasite which of itself might be wholly inefficient due to its slow rate of reproduction as compared with ‘that of its host, might be rendered very efficient by the co-operation of a con- tributing factor which could only delay the rate of increase. It will thus be readily seen that the efficiency of all these tactors working together is neither the sum nor the average of the potential efficiency of each, though much nearer the latter than the former. Many writers have assumed that by adding anew parasite, its efficiency was simply added to that of others previously existing. This supposition ic certainly far from the theoretical conception of the inter-rela- tions of species as presented above, and has not been borne out in actual ex- perience. RELATION OF LIFE CYCLE oF Host. Thus far the insect whose control is sought is conceived of as existing in but one condition. The growth and trans- formation of insects add still further complications to the subject. The checks are not simultaneous in their action, but at each stage in the progress of its development the insect lives in a different environment. The parasites, 54 [JANUARY, 1909, for instance, that affect the egg will find the next generation of eggs perhaps more profoundly influenced by the checks that have operated during the remainder of the life of the insect than anything they have accomplished, and so perhaps with the checks operating at any stage. apg, Ory pe Owe wey a is Se eC CU eC Cc ehlc er ae ee ee, ashciameel iii la aa A Bh ' JANUARY, 1909.] 61 WIND-BREAKS FOR ORANGE GROVES IN PORTO RICO, Orange cultivation is an industry of considerable promise in Porto Rico, and numbers of plantations are now being set out. A pest which is causing a good deal of trouble in the citrus groves is the orange mussel scale (Lepidosaphes beckii, (Mytilaspis citricola), and the 1907 Report of the Agricultural Experiment Station of the island mentions that xperiments are in progress to determine he best methods of dealing with these insects. Spraying with kerosene has given fairly satisfactory results. It is stated, too, that Porto Rican planters now recognize that wind-breaks on the wind-ward side of the citrus groves play an important part in checking the spread of the scales. The following notes on this point are taken from the report :— Wind-breaks are divided into two classes—permanentand temporary. Per- manent wind-breaks are generally plan- ted on the outer borders ot the groves, while temporary wind-breaks are planted between the rows of trees. There are several plants which grow very quickly, and afford good temporary wind pro- tection, namely: bananas, sugar-cane. pigeon peas, and the China berry or Barbadoes lilac (Melia Azedarach). Tem- porary wind-breaks should not remain between the rows more than three years and in the case of bananas a furrow should be ploughed on each side, thus preventing the roots from sapping the soil around the orange trees. For permanent wind-breaks at the present time the mango seems to be the best, but in setting out the young trees they should be headed as low as possible. Bamboo is also being planted, and if the cuttings are set out during the rainy season they start much quicker... These should be planted close together, so as to form a hedge. When brush land is being cleared for planting, it is advisable to leave a strip of uncut timber 20 feet wide every 300 to 400 feet. The results obtained from wind-breaks are very marked, certain groves which were wind-swept and were not growing at all having been brought into excellent condition. In almost every grove in the island marked im- provements have been observed as the result of planting wind-breaks. In certain areas there may be found trees producing from 1 to 2 boxes of fruit, while trees not more than 50 to 70 feet away, and of the same age as the former but without wind protection are fre- quently noticeable, which, from their development, might not be more than a year old. On the latter the branches are blown to one side and covered with scale. Trees protected from the wind require less spraying, and the fruit is free from scars.—Agricultural News, Vol. VII., No. 165; August, 1908. GREEN MANURING. In India manuring is yetin its empiri- cal stage. The science of manuring, its mode of action, the improvements of the methods available and the return to the soiloft all that is taken from it are not sufficieutly known. The use of green manures might be especially re- commended to the Indian agriculturist, especially on account of his poverty. Green manuring consists of growing acrop of some sort, usually a legumi- nous one, and ploughing it into the soil at the time of flowering. Modern science has up to now determined ten chemical substances in plants, viz., carbon, hydro- gen, oxygen, nitrogen, sulphur, pihos- phorus, potassium, calcium, magnesium, and iron, Of thesechemical ingredients, nitrogen, with which organic matter is closely associated, has been generally recognised to be the most important. The growing of leguminous plants be- tween the lines of the staple crop has been found conducive to the accumu- lation in the soil of a sufficient store of organic matter and nitrogen. Nitrogen in its free form is largely presentin the atmosphere ; but the plants have not got the power to utilise it. The diffi- culty is that they require a medium to render nitrogen available to themselves. An experienced agriculturist describes the utility of leguminous crop in this respect thus :—‘ First rains, lightenings and other natural causes tend to unite the free nitrogen with hydrogen, oxy- gen and other substances and com- pounds, which falling down along with rain, enter the soil and mix with the earth (technically called metallic bases ) and forms salts of nitric acid. Hence the starvation of the plant for nitrogen in the presence of plenty of free nitrogen in the atmosphere. _ It requires a medi- ator and a process before the nitrogen can be of usein itsformation,...... Of the several thousands of natural orders of plants, modern science has determined that a certain natural order Scientific Agriculture. 62 known as leguminous (Pulse order) has the power of utilising the free nitrogen of the atmosphere into its own consti- tuents. This it does either directly by making the free nitrogen unite with its own substances or indirectly by making it unite with other substances in the air and then utilising it for its own purpose.” Green mauuring is not a new system of manuring for India. It appears to have existed in various parts of India from very early times, though its rationalistic explanation in the light of agricultural chemistry was _ not known. Itisthesame as what is known as the “ Pachaithol valar” in Malabar, Travancore and other places on the West Coast. Leaves of certain kinds of trees, such as Portia or Silanti (Thes- phesa populnea), Erukku (Calopropis gigantea) Mango ( Nanagifera indica.) Avarum (Cassia agriculata) are in these places commonly used as manure for field crops. A few months prior to the cultivation of the staple crop, horse gram is usually grown in the fields with a purpose to produce leaves to get them ploughed into the soil. In the case of the trees mentioned above, their leaves are chopped and applied to the soil soon after ploughing, in order that they might mix with the earth and decay. In some cases a few of the staple plants are taken en masse from the ground and in that spot cropped leaves with mud are put in and over this the plants are placed so that they might strike root below in the manured ground. Even leaves of ordinary jungle trees are largely used as manure. Thus it will be seen that our old farmers had some idea about the utility of the appli- cation of green leaves to the soil. They knew that when some plants were plouged into the soil or are simply raised on it, the soil becomes exceedingly pro- ductive. But it was only atthe end of the last century that the German chemist made some investigations on the subject and discovered that these leguminous plants develop certain nodu- les at their roots which serve to accumu- late millions of nitrifying bacteria. This genus of plants known as legumi- nose ( Pulse order ) were found to enrich the soil in which they grew. They have the peculiar power to absorb from the atmosphere more nitrogen than they require. They take just what they want for their growth and leave the surplus in the soil, In the above, we have shown what “Green manuring ” is. One of the important properties of green manure is_ nitrification. Besides . nitrification it has also other JANUARY, 1909. properties. When the various parts of these: leguminous plants get de- composed and get mixed with the soil the particles of the soil are made to recede from one another, and as a result the soil gets loosened. Thus these green manures serve to assist in the physical growth of the staple crop. Again, the decomposition of vegetable substances causes the evolution of car- bonic acid. Plants, we know, are unable to assimilate any substance except in solution. Itis for this reason that water is so necessary to plant life. The pre- sence in the soil of carbonic acid or its source in the form of decomposing plants is highly useful for the healthy growth of plants; for carbonic acid has the property of dissolving various com- pounds which are insoluble in water. Side by side with these advantages, there is, perhaps, one minor disadvantage. The decomposition of organic substances also causes the evolution of sulphurated hydrogen, which is extremely injurious to plant life. But the evil effects of this gas might be considerably minimised by turning up the earth more frequently ee when other manurial agents are used. Various plants are used as green manure. Which of them is best cannot be definitely said. It largely depends upon the nature of the soil and the variety of the staplecrop. For instance, horse gram, which is known to be a good green manure, proves a failure when tried on a crop of black gram. In a lecture delivered by Mr. Herbert Wright some time ago he mentioned the use of Crotaralia striata, ground-nut, dadaps and albizzia as green manures best suited for tea plantation. They are found equally useful in the case of coffee, cocoa and rubber. There are other green manures, such as mimsoa pudica, certain varieties of cassias, tephrosia purpuera and Sesbania Grandiigna, which might be used with great advantage in coconut and tobacco plantations. Mr. Wright is a staunch advocate of ‘‘Green manur- ing.” He believes ‘‘ that the growing ot leguminous crops, besides enriching the soil when dug in, keeps the temperature of the soil more uniform in both the damp and dry seasons, breaks the force of rain and reduces the amount of wash, prevents the loss of plant food by the percolation of water and drainage, and helps to keep the weeds in check.” Of the green manures ‘mentioned above, Crotalaria striata is not very commonly used as green manure. The seed of Crotalaria striata is sown broadeast and the plants may be uprooted within six or eight months after sowing. It yields a large amount of a green organic a a ee ee “ 4 % B 3 ; 3 | 5 JANUARY, 1909. matter, giving over 6 tons per acre. Six tons of green organic matter as manure are equal to more than 100 lb. castor cake. Its use as green manure is confined to some Ceylon tea _ plant- ations and on a small scale to some of the tea districts in India. Groundnuts have been found of greatest advantage for the purposes of green manure. This plant has a trailing habit. It does not grow beyond a height of one foot and it dies down in six months, It can thus be dug in with the soil very easily. Further, the cultivation of this plant is very simple, the seeds being simply thrown into the holes of an inch deep. The one great advantage the ground- nut thrown has over Crotalaria is its small amount of tissue and its very thin stems and leaves, which are readily taken up by tea or other plants. It has been found that ground-nuts provided a large quantity of nitrogen, 9,000 Ib. of the green material yielding as much nitrogen as 1,500 lb. castor cake. The Albizzia, which belongs to the genus known as Albizzia moluccana, is not much of a success asa green manure. Crotalaria is much superior to _ the Albizzia in the matter of the supply of the organic matter, Of course, in the absence of other green manures it may be used in tea plantations. In addition to those mentioned above, there are a lot of other legumes. Cajanus indicus (Dal) is a very useful plant that might be profitably used asa green manure. This plant, though not a native of India, has become well acclimatized, having been introduced into India from tropical Africa some 3,000 years ago. It can be cultiyated at a small cost. With the beginning of the rainsit might be sown, aid cut down as soon as the crop begins to ripen. This plant is known by various names. It is known as Thovaray in the Malabar district on the West Coast. There are many other plants of the pulse order that might be used as greenmanures. Experiments are being made in the cultivation of some of these plants as green manures in the hope of discovering something which do better than any of the above. Thus far about green manuring and its advantages. We shall now point out another feature of green manuring. Great care should be taken in the choice of the plants for purposes of green manuring. In some soilscertain of these leguminous plants do not develop nodules at their roots. This means that these plants are abstracting nitrogen from the soil instead of adding to it. The development of nodules depends upon the nature and variety of the soil; and, as such, every leguminous plant, 63 Scientific Agriculture. before being cultivated as green manure; must first be experimented upon. Again, in the matter of examination of roots for nodules, it must be remembered that all excreseences that may be seen at the roots of plants cannot be taken for nitrogenous nodules ; for there had been instances in which such excre- scences which might appear at first sight to be real nodules were producted by nematodes. The subject of nematodes and the incalculable mischief wrought by them to plantations is still engaging the attention of agricultural experts in India. A bulletin on nematodes issued by Mr. C. A. Barber some five or six years ago, gives a large fund of informa- tion on the subject. In his opinion the remedy is to destroy every plant infested with this tiresome pest. The best way to distinguish nematodes from nitro- genous nodules is to examine the roots with a microscope. To the naked eye the differences may not be visible. There are two kinds of nitrogenous nodules, one nearly globular in form and the other flat and grooved, having the appearance of minute finger-like projec- tions from a common centre. On the whole it might undoubtedly be said that green manure is cheaper and in many respects better than other varieties of manure. Green manuring has been found especially useful in the case of lands reclaimed from jungle for cultivation. It proves beneficial to such lands in many ways. The fertilising ingredients which would otherwise have been washed away are utilised by these green plants. Further, they add to the quantity of carbon in the land. All possible endeavours should therefore be made to induce our ryots to go in for the use of green manures more largely than they do at present, especially in view of the fact that in India the soil in many places has already begun to feel the strain of cultivation to which it has been almost continuously subjected during centuries.—Indian Agriculturist, Vol. XXXIII., No. 7, July, 1908.

In the West Indies Sea Island cotton is chiefly grown as a subsidiary crop to suyar-cane and not as a main crop. In the Sea Islands, however. and in Carolina and Georgia, where Sea Island cotton is grown atall, it usually forms the most important and profitable crop in the rotation. Under these conditions, one of the chief points needing atten- tion by the cotton farmer is the best means of maintaining the fertility of the land for cotton cultivation. Artificial manures are frequently applied, but in Farmers Bulletin 302 of the United States Department of Agriculture—‘Sea Island cotton,’ it is stated that one of the chief factors for keeping the land in good condition is the adoption of a rotation in which leguminous crops are prominent. Cow- peas, velvet beans, and peanuts, all of which have been recommended for cultivation in the West Indies, are the chief crops of this kind grown, being found to give excellent results on the light soils most suitable for Sea Island cotton, and the rotation frequently extends over no more than two years, cotton being planted in one season, and a mixture of corn and cowpeas the second year. On the whole, it is stated, the cowpea (Vigna catjang) is the most popular and widely-grown leguminous crop for growth on Sea Island cotton land. The peculiar advantages of this crop are that the plant is well adapted to poor land, it is easy to cultivate, and the produce is valuable as food for man and stock. The Iron cowpea is specially recommended for growth in connexion with cotton. The velvet bean (Mucuna pruriens, var. utilis) is another crop which con- stitutes a valuable source of humus, and adds a large amount of nitrogen to the soil on which it is grown, This plant grows very vigorously, and _ its vines afford excellent fodder for stock. The plant, too, is immune to most diseases.—The Agricultural News, Vol VIL, No. 165. August, 1908. PLANT PHYSIOLOGY. What we do not know about plant physiology will require the writing of many books and the realization of much experience before (lhe agricultural ; q ; JANUARY, 1909.] 6! world will reach common ground in relation thereto. Animal physiology, including human physiology, has been making rapid strides, through the last two or three decades, largely because of its investigation along industrial and economic lines. So far as the work has been left to the medical fraternity, un- happily, they have not been able to develop much that is new; they, as a rule, being not only overworked, but underpaid in their ordinary vocation. The investigations of animal life by our scientific agricultural institutions have done much to aid humanity. All of this, however, left plent physio- logy in the background and, as we now stand, we hardly know how plats live, breathe, drink, eat and die, as apparent- ly they allmust do, and probably simi- larly to all other living beings. In a recent issue of the West India Agricul- tural News there is reprinted from the Memoirs of the Department of Agricul- ture in India an article entitled ‘‘The Toxic Substances Excreted by the Roots of Plants.” We reprint thisin another column in this issue, but desire to cast our opinion against the accuracy of its conclusions, even if we have to use the Scotch verdict of ‘‘ not proven.” [Given in the last issue, page 563. | The general tenor of the argument used is that some crops are found to do very poorly after certian other crops, when grown upon the land the follow- ing year. The inference is that the pre- vious crop has secreted some toxic ele- ment inthe soil inimical to the more recently planted crop. The first refer- ence is made of cotton crops grown in Egypt, in which a certain grass was permitted to grow as a weed. It is recognized everywhere that grasses are inimical to the best growth of our so- called hoed crops. Just why this is, it is difficult to determine with the data we have, but we are led to believe that the grasses growing in with other crops consume the air, moisture and plant Scientific Agriculture. nutrients of the soil and, generally, being indigenous, they are quite hardy and difficult to extirpate and survive in the contest that they are making with the cultivated crops, unless positively hoed out. Why one crop following the other should be bettered or injured because of the previous crop, is not so well under- stood. It is understood that alegumi« nous crop enriches the soil and that any crop following it will probably be much benefited thereby. Sweet potatoes are not leguminous and yet we know that sugarcane will generally do very well in land that has been in sweet potatoes the previous year. We presume that this is owing to the fact that the sweet potatoes occupy the ground to some depth, and in their planting, cultivation and harvesting the soil will receive a degree of tilth not ordinarily given to standard crops like sugarcane and cotton. Weare very much inclined to think that the author of the article in question is guessing at his conclusions, and this particularlyas given in the fourth statement that the substance excreted by all crops is probably iden- tical. All plant analyses show that the plants consume different quantities of the mineral constitutents of the soil. If the plant absorbs all of its nutrition mineral constitutents included, through its roots and in solution with water, then the excretion is, we belive, sent into the air through the leaves. And we believe that the apparently toxic effects of previously grown crop, on given lands have their origin in the exhaustion of the lands by the growth of such crops rendering them less fit for the successful production of subsequent crops.

Dry-land farming in the Madras Presi- dency offers great scope for investiga- tion and improvement. In many dis- tricts such as Bellary, Cuddapah, Ananta- pur, Kurnool, Guntur and Nellore, the implements in use are admirably adapted for dry-land farming, but in the south, the plough and the land-hoe are the oy common implements used for dry- ands. Successful dry-land farming is inti- mately connected with the conservation of soil moisture, and the object of this article is to show how far this can be accomplished by judicious tillage under the conditions prevailing in the Madras Presidency. Before discussing the sub- ject further it is necessary to explain the meaning of the term “soil moisture ” as well as its sources and how it may be retained or lost. Soil moisture is the water which is held in the soil after the surplus has been allowed to drain away. This is necessary to dissolve the plant food which is in the soil and to convey it to the plant roots, but the surplus of drainage water is inimical to the healthy ‘growth of plant as it prevents the aeration of the soil. The sources of soil moisture are rain, subsoil water and atmospheric moisture. Rain is the chief source, and it is of the greatest importance that the land should be prepared to receive it. A hard-baked surface cannot absorb much water; therefore, the surface should be loosened by tillage so that the rain can penetrate the soil. Subsoil water is another im- portant source. Not only does the sub- soil relieve the soil of its surplus water, but it can replenish the soil moisture when helped by proper cultivation. Besides these two main sources, the soil can by its hygroscopic properties, not only absorb moisture from the air, but can retain this in considerable quantities if a good tilth is secured. Thus, in parts of Madras the heavy dews which are experienced are of great value. The retention of soil moisture can be assisted by surface cultivation which gives a loose surface soil or dry mulch. Deep cultivation and a firm soil will assist in keeping the soil particles to- gether, and thus cause a more even distvri- bution of moisture through the soil. The following deseription will show how these principles are carried out in the dry-land cultivation of Madras. For this purpose the Presidency can be roughly divided into two tracts. In the former draught implements other than the plough are used, and in the latter the plough is, as a rule, the only draught tillage implement. The former includes the black cotton soils of Bellary, Cauddapah, Anantapur, Kurnool, Guntur, and part of Nellore, as well as the lighter soils of these and of the Kistna district. In the black cotton soil of this tract two types of plough are used. One, a heavy wooden plough which has now been largely superseded by a heavy iron one, and the other a much lighter | wooden plough. The heavy plough is only used once every five or six years, and is followed by a very heavy bullock hoe, known as a “‘ Bara-Guntaka ” which works to the same depth as the plough- ing. What benefit is derived from this latter operation is difficult to see. The plough works the soil to a depth of a foot or more. Ploughing is done during the hot weather and huge dry clods of earth are poised up and beneficially ex- posed totheair. In other years either the light country plough or the bullock hoe called a Guntaka is used for preparatory cultivation. (Plate X VI.—vide p. 67.) In the lighter soils of this tract this deep ploughing is not practised. Preparation for Sowing.—This work is usually done with the bullock hoe or Guntaka. If worked after the land has been ploughed, it isa very useful imple- ment. It makes a fine firm seed-bed and brings any larger clods of earth to the surface which are broken down by subsequent rains. The practice of work- ing the soil with the Guntaka without previous ploughing is sometimes prac- tised. This is objectionable as only the surface is loosened and the soil below remains hard set and lacks aération. Occasionally, when the rains are very late, some such method of cultivation has to be resorted to, but the ‘‘ Gorru” or seed drill without the bamboo sowing attachment is preferable to the Guntaka.

It regu- lates the space for each plant. Sowing can be done when the land is com- paratively dry, asthe drill can be set to sow at the depth where there is most moisture. Good germination is assured gad there is a considerable saving of seed. A fter cultivation.— Several implements are in use in different parts for this work, but the best are the Dunthalu which is used in the Bellary District, and a small Guntaka, which is a similar implement with a wider blade, and in the case of cotton and red gram is often ussd after the cereal catch crop has been reaped. The others work deep and throw the soil up round the plants form- ing ridges and furrows. . The Dunthalu consists of aset of three to six small bullock hoes which are jattached to a wide yoke pole and is drawn by two bullocks (page 67). Each hoe or danthi has an iron blade some 9 inches wide, which the driver guides between two rows of the crop. The hoeing is done after a good rain has fallen, but as a rule the farmer does not seem to realise that the operation is just as necessary when the surface has caked after a light rain, and,in consequeuce, this implement is seldom worked more than two or three times.* Throughout the Tamil country and in Malabar the plough is, with few excep- tions, the only tillage implement for dry cultivation. In Malabar the conserva- tion of soil moisture is not so essential owing to the heavy and continuous rain- fall during the growing season. Plough- ing commences with the close of the monsoon, and is continued afterwards until the early sowing rains commence in April and May. Inthe dry Eastern Tamil country the rainfall is limited, and does not admit of repeated plough- ings before the sowing rains. The land is usually left untilled until a ploughing rain falls, when as large an area as possibleis ploughed. Aboutfour plough- ings are usually given. The ryot then waits for a sowing rain when the seed is sown broadcast and lightly ploughed in. The subordinate pulse crop, usually Cajanus indicus or Dolichos lablab, is sown immediately afterwards, the seed being dropped behind a light plough. Ina few districts the value of a firm seed-bed is appreciated, and after sowing, the soil is made firm by dragging a roughly made brush harrow across the This practice has many advan-, (JANUARY, 1909. ploughing. In parts of Tinnevelly also the ryots cultivating red soil have an implement made like a large wooden rake which is used to break the surface crust and assist the growth of the young crop. hen the crop is established, the plough is worked through it. This rough and ready method of cultivation gives a good crop in good seasons, but if the rain fails, the result is often a partial or complete failure. In parts of South Arcot this practice of ploughing through the crop has been entirely given upin favour of the more efficient practice of hand hoeing. Here the dry cereal is considered as a catch crop for the groundnut crop, the seed of which is dibbled in after the cereal is well established. The land is often hoed two or three times. The first hoeing includes weeding and thinning, while the others are mainly for loosening the soil surface, and is done even if the land is perfectly free from weeds. The in- troduction of the harrow into the Tamil country would bean immense advantage. If used instead of the plough, the surface soil alone svould be loosened and thus the soil moisture would be better con- served. The ground would be left level instead of in ridges and furrows, which are always objectionable in the case ot a dry crop asthe ground soon dries out and subsequently rain runs down the furrows before it can soak in. If the harrow were used instead of the hand hoe, the cost of the work would be greatly reduced and the farmer would be able to complete the work in less than a quarter of the time. The time that this operation takes is of great im- portance on the lighter soils. A harrow made in the shape of an equilateral triangle has been found to answer this purpose well, and is not too expensive or too elaborate for the ordinary culti- vator. This and other implements used in dry cultivation are illustrated.—Agri- cultural Journal of India, Vol. IfI., Part [., January, 1908. AMBALANGODA VEGETABLE SHOW. HELD UNDER THE AUSPICES OF THE WELLABODA PattTu (GALLE) Locat BRANCH, 19TH Dec., 1908. This show was opened by the Government Agent, Southern Province, and was attended with success. It was the second Show for the year, the first being held at Hikkaduwa in the latter part of February. The exhibits were confined to vegetables, of which there were large collections. Consid- ering the lateness of the vegetable season, the exhibits were good. Many of the exhibi- « —— oe ‘ ; 4 JANUARY, 1909.] 69 tors had also competed for the awards for the Vegetable Gardens and Transplanted Paddy plots for which separate prizes were given. In judging I had the kind’ co-operation of Mr. de Livera, Atapattu Mudaliyar, Matara, and Mr. J. M. Wickramaratne, Proctor. The awards included four cash prizes and two certificates, and three special awards were recommended for single specimens of capsi- cum, snake gourd and tea. Capsicum, chillies, pumpkins, cucumbers, melons, brinjals, kekiri, and bread-fruits made a very good show. Of yams there were excellent collections, sweet-potatoes and cassava being parti- cularly good, Some good oranges and jak-fruits also found among the exhibits. N. WICKRAMARATNE, Agri, Instructor: were RURAL AGRICULTURE IN CEYLON: AND HOW IT MIGHT BE IMPROVED, THE DISCUSSION. The reading of the paper on the above sub- ject (given on page 569 of the Dec. issue) by Mr, W. A. de Silva, before the meeting of the Board of Agriculture on the 3rd December. was followed by the following speeches — Dr. WILLIS AND THE NEED FOR AGRICULTURAL ‘* PRELIMINARIES ”’ Dr. Wiis :—I think, Sir, it is a very satisfactory sign of the times that the Soc- iety is beginning to realise clearly that before you can make progress in Agriculture you have to make progress in the preliminaries of agriculture. In Ceylon we have hardly yet got through the preliminaries, and yet we have been trying too much to attend to the agricultural part. With regard to Kuro- pean planters they have passed, so to speak, through the preliminaries ; but the native cultivators have not, and it is consequently almost idle to introduce new things amongst the villagers, because they have not got the necessary preliminary conditions to go on with. The two principal things on which the whole industry rests are FINANCE AND TRANSPORT, and unless we have sound conditions as regards these it is hopeless to go ahead to any serious extent and get the people to take any great interest in growing things which must be sold in outside markets. Consequent- ly it is a very good thing to see that these papers tend to increase generally the interest taken in the question of the small co-opera- tive systems for the supply of money. I use the word in a broad sense. It may be in the supplying of paddy seed, in manures, in sell. Miscellaneous ing produce in Colombo. It may be anythin& you like, but the central principle is co-opera- tion amongst the poorer classes, to enable them to carry out what would otherwise require the capitalist to put through. In this country I have been trying to induce town Societies, who have, presumably, a little money, to help their village brethren— for whose benefit, after all, we were estab- lished, —by starting co-operation for the sale of produce and the supply of manures, and soon. The ordinary villager has no money at all, and consequently he cannot hope to do anything beyond live from hand _ to mouth, I think, therefore, it is very satis- factory indeed to see the tendeney which is coming over the whole country to attend to these preliminaries. Transport, thanks to Government, is very well developed on the whole in Ceylon and there are sufficient, villagers along the branch roads and railways to carry out any agricultural improvement that is necessary. ‘The essential weak point of the whole Ceylon system of agriculture is money. To raise the people to a higher plane you must first of all attend to the preliminaries of agriculture, and find them money, This must be forthcoming before you go ahead in agricultural matters strictly so called. *(Hear, hear.) GOVERNMENT'S ATTITUDE, H. EK. the GOVERNOR :—Equally with Dr. Willis I welcome the appearance of two papers such as those under discussion. Members may recollect that when I assumed the administration of the Colony I hesitated, as naturally I would do for some little time, to give an expression of opinion regarding the agricultural requirements of the Colony. However, you gentlemen have seen, and the community generally have seen, rather lengthy references to loans to native agricul- turists in the despatches which I sent to the Secretary of State. The Secretary of State has approved of the proposal that funds shall be voted to assist agriculturists, but he requires regulations on the subject to be submitted to him. It is particularly valuable tome as the Governor of the Colony to have papers before me such as those which have been read or taken as read, and 1 may say I shall welcome any expression of opinion and recommendation from those who are qualified to write upon the subject and advise how best agriculturists can be assisted in such a manner that we do not pauperise * It may make matters clearer if we add the following note. The preliminaries to agriculture are land, climate, labour, transport, capital, drainage irrigation, tillage, education, and suitable crops. The most important are land, capital, education and transport, so far as Ceylon now is concerned and until the villager has land ayailable, transport facilities, and capital to work any improved method or new crop, he cannot progress beyond his present state. We called attention to this at the very first meeting of the Board,—Z£d, Miscellaneous. them more than these poor fellows already are. We want toincrease their self-respect and at the same time deliver them from the clutches of the money-lender. It was at a very early meeting of this Society that I referred to the system of usury going on in this colony. It was my endeavour to grapple this ogre of usury, but when it came to prospective legislation I found the whole matter was rife with difficulty. It was in consequence of this that I came to the opinion that it was the Government them- selves who must come to the assistance of the people—train the people, educate the people, help the people. As Mr. de Silva has said, this must be done on strict business principles, It must be done by co-operation with the people, working with the people, and the people themselves must do a great deal to come to the state of perfection to which Mr. de Silva points out now exists in Denmark. We have of course a very up- hill game to fight. Our Ceylonese cultivators, unfortunately, are extremely apathetic and have to be shown the value of labour. I quite fall in with Mr. de Silva when he says their efforts through the year should not be devoted simply to the paddy patches, but that they should go in for other means of making a livelihood. It may yet be found that by improving the state of agricul- ture generally that the solution of the food question is not to be found altogether in the extension and development of rice fields, but that other food products may be raised such as Indian maize, which is not received with that disfavour which it once was. As I say, the members of the Society and the Government,—everybody concerned who takes an interest in agricul- ture—have a weary, stiff problem before them in order to bring this lesson home to the people. For instance, Mr. de Silva points out quite rightly the wretched yield of rice per acre. What is that due to? It is duein a great measure because the people will not transplant the paddy, except in a few districts such as Kegalla and on the South Coast, but will still insist on scatter- ing the paddy broadcast and rearing it in a way which gives small returns on a wasteful expenditure of seed paddy. H. E. then repeated that he would be only too glad if communications such as he had re- ferred to were sent to his Private Secretary. THE QUESTION OF BURMA RICE. Mr. F. C. RoLEs :—Your Excellency, may I be allowed to make a few remarks on Mr. de Silva’s paper? My attention has just been directed to a reference in the paper to the subject of Burma rice. That is a subject of much and of growing importance. I have hada few words with Mr. de Silva and pointed out to him that there is no prejudice amongst the labourers against Burma rice. Itis the raw product only that they object to because of their [JANUARY, 1909. method of boiling once in 24 hours. Steamed rice has been imported from Rangoon, which has been highly reported on by a number of estate superintendents, kanganies and coolies, The remarks regarding white Burma rice, farther on in the same paragraph, has re- ference torice which has been imported, here for many years. It is used for con- fectionery and hoppers and not on estates, and it is white Burma rice because the inner skin has been removed; that skin is left on in cargo, or Loonzain rice, which is the kind of rice required for consumption on estates. By a second hulling the number of paddy grains can be reduced to a minimum of 2 per cent. If that paddy is steamed first and hulled afterwards it is entirely acceptable to the consumer. Now it is simply a question of price and further efforts are being made, as a sequel to the discussion of the subject in Ceylon and in Rangoon and neighbourhood, in steaming on a small scale. At the present time there are small shipments in the off season; and considerably increased quantities are expected in the coming season. (Hear, hear.) AN EGYPTIAN AGRICULTURALIST’S VIEWS, Mr. J. S. J. McCall:—Your Excellency, gentlemen: Althouh a visitor, 1 would like to saya few words in answer to this question of loans to agriculturists, as we had the very same problem in Egypt, where I was Agricultural Lecturer for three years. We could not get money to improve matters. But, by the Government taking an interest in the subject, we managed to get the leading agriculturalists in the country—those who had the money—to form among themselves an Agricultural Society, and a large num- ber to. put money intothis Society. The Society purchased manures from the manure firms, guaranteed their purity, distri- buted them to the different villages, and sent men who were qualified to deal with the question of manuring to superintend the application of the manures to the village fields. At first the manures lay by the hundredweight in the villages, and the villagers said : ‘‘ We will not touch them, We have been culti- vating rice, wheat, barley and the different crops of the country for centuries, and we are not going to alter our methods”—in the true Mohammedan style. The Society replied: ‘* We will present to you these manures. You may apply them to half your fields, the other half do with as hitherto in your methods and compare results. If your crops suffer from the application of the manures, we, as a Society, will guarantee to compensate you, but if the crop benefits over the price of the manure we will ex- pect you to pay us the price of the manure.” That was the state four years ago, and the result was that last year the Khediveal Agri- cultural Society imported £175,000 sterling of artificial manures. and could not supply the natives quick enough. We absolutely + ‘i Bi fl JANUARY, 1909.! could not get the manure into the country quick enough; and the effect of manuring on the general agriculture of the country was that, four years ago, the price of straw, etc., in Egypt was nearly double the price that it is at the present day, as the increase of crop owing to the beneficial action of the manure put a larger quantity of pro- duce on the market. Some people might think that this. would result in no benefit to the cultivator ; but that would be a mistaken idea, as artificial, manures applied carefully, in the correct proportions and the correct manures to the correct crops, seldom give less than 100 per cent, on the cost of the manures. The natives of Ceylon know nothing about manures, but that is not to their discredit. Only 10 years ago in Great Britain there were very few farmers who knew anything about artificial manures, Some people have the idea that manures are very flexible quantities: this is also a fallacy, as a manure has only a definite value and can only give a definite increase, and this increase to alarge extent is dependent on the right manure being put to the right crop, Dr. Witiis—referring to what Mr, Mc- Call had said—remarked that he had been round the districts where at present artificial manure is unknown. Some said they knew nothing about itand some said once manur- ing was started they must goon with it. That was of course true. It was an essential condition to progress in anything. He said it had been pointed out, and the suggestion he thought was a sound one, that it would payin the long run if the Par- ent Society in Colombo were prepared to supply local societies with small quantities of selected manure for trial in the districts. That might be tried on the lines Mr, McCall spoke of. NOTES AND QUERIES. G. E.—The Centre of Agricultural Education in the Madras Presidency is Coimbatore, where'there is a College and a farm of 450acres, Apply to the Principal for syllabus. The course is a three years’ one. ; W. DE S.—The cultivated anatto bears a pink flower, but there is also a white variety. It is the former that is commonly cultivated, but the white flowered variety is found semi-wild in India, the natives believing thatit is indigenous. The principal use of the dye is for colouring butter and cheese. It isusually dissolved out with olive oil. ToMATO.—The following system of manuring tomatoes is reeommended by the Queensland Agricultural Journal :— 2 parts nitrate of soda,2of bone meal, Miscellaneous. 3 of kainit, 4 of superphosphate. Apply 1 oz. per sq. yard weekly, slightly cover- ing, from the time the plants are estab- lished till the fruit has set, DanicHA.—This is an Indian name for Sesbanea aculeata, which is well thought of asa green manure and is also a fibre plant. It is closely allied to our * Katurumurunga” and is being grown experimentally at the Government Stock Garden. B,—The author of ‘The French Garden” is C. D. McKay, F.R.H.s. He describes the work as‘‘A diary and manual of intensive cultivation.” The book can be consulted in this office. F, KE. F.—No, the cherimoya will not do at Colombo elevation, so that you may not grow this delicious fruit in your own garden. M. G.—The Coorg is a much smaller orange than the Nagpur. The latter is more after the styleof our best King oranges. ““CHow McLuiER.”’—This is being tried at the Government Stock Garden. The plant belongs to the cabbage family, Its value is as a cattle food. GARDENER.—Have you tried bone meal? I would recommend your giving up heavy applications of cattle manure for a time, as the orange trees have most probably had enough of. nitro- genous food and want more of. phos- phate for fruit formation. THE LITERATURE OF TROPICAL ECONOMIC BOTANY AND AGRI- CULTURE. SCEOND SERIES. By. J. C. Wiis. _We propose to go on publishing this literature, which we find is regarded as very useful by many correspondents scattered over the world, and begin to- day a Second Series. While at first these lists were con- cerned almost purely with economic botany. they have gradually had other subjects added to them. The date of each new heading may be ascertained from the dates of the articles mentioned under it, and noattempt has been made to go back. Mr. Lock, who will act for me during my absence, having undertaken to keep up the lists of literature, there will not be the same gap as there was in 1902-8, Miscellaneous. It may be worth remarking that under such heads as Sugar, Vines, etc., no attempt is made to keep up with tem- perate-zone literature. Aberia—cf Fruits. Willis, Miscellaneous Economic Plants I.

So full of beauty and charm is the rose, and so numerous are the _ points of interest connected with it, that chapters could be written about it. In all ages and by universal consent, throughout the civilised world, undisputed precedence among fiowers has been conceded the Miscellaneous, rose, “ Queen of them all.” The favour- ite flower for all time, as such it has place in general literature that no othe pine can rival. In the sacred writings, y classical authors, by the poets of all countries, this ‘‘Queen of Flowers” i the epitome of beauty and fragrance, the emblem of refined sensual enjoyment, ‘richer and sweeter far than aught betore.” The rose is woven in the ancient Greek Anthologies. In the Planudean Anthology occur some beauti- ful couplets ascribed to more than One writer in which the wish is breathed : Oh that I were yon blushing rose, Which even now thy hands have pressed, That 1 might love in sweet repose, Reclining on thy snowy breast ! Plato presents a lovely picture of the God of Love laid asleep among roses, with the bees settling upon his lips ; and there is a favourite passagefrom Julian - Twining a wreath, [ found one day, Love that among the roses lay. Therose was dedicated to Awrora as the emblem of youth; to Venus of beauty ; and toCupid of fugacity and danger. The latter is said to have given it asa bribe to Harpociates the God of Silence, hence the saying ‘‘under the rose.” Modern feelings have run into the same sort of amorous fancy as that of the earlier writers, for have we not Romeo in Shakespeare expressing the wish ‘‘Oh that I were a glove upon that hand,” etc, Burns who it is thought knew little or nothing of the Greek anthologists seems to have fallen into their style and instinctively adopted their spirit : Oh that my love were yon red rose That grows upon the castle wa’, And I myselfa drop of dew, Into her bonny breast to fa’! _ And we have writers all along descant- ing on the admirable qualities of the rose. It has been the subject of scientific monographs and of floricultural disquisi- tions, and many are the writings extant about it. The species which has been CULTIVATED FROM THE HIGHEST ANTIQUITY, is supposed to be Rosa Centifolia, the Cabbage or Province Rose, a flower which possesses in an eminent degree the admirable qualities of the tribe Roses have been grown for so many centuries and have been crossed and recrossed so often that itis difficult to refer the cultivated forms to their wild prototypes. The older roses are thought to have orginated from R&R. gallica, a native of Central and Southern Europe, Miscellaneous. R. Centifolia, a native of the Caucasus, contributing its share. Under natural circumstances rose flowers do not secrete honey, the attraction for insects being provided, according to Muller, by the colour and perfume and the abundance of pollen for food. The cuitivation of the rose affords employment to thousands of human beings— cultivation for the table and for the manufacture of attarand rose water. R. damascene is cultivated in somo parts of Roumelia and in India, chiefly near Ghazipur, for the purpose of making attar and rosewater. Drury mentions that it takes 200,000 roses to yield the weight of a rupee in attar and this quantity sells on the spot for R100. In Europe rose water is chiefly produced from R. Centifolia, grown for the pur- pose at Micham, and much more abun- dantly in the South of France. Conserve of roses and infusion of roses, two medicinal preparations retained for their agreeable qualities rather than for any special virtue, are prepared from the petals of KH. gallica, says an old writer. Conserve of dog roses is made trom the; ripe hips of the dog rose, R. eanina. Its only use is IN THE MANUFACTURE OF PILLS. The cosmopolitian character of the rose is wellknown and it flourishes equally well in sub-Alpine as in equatorial re- gions; and the patient skill of cultiva- tors has been successful in depriving it of one of its attributes—it has ceased to be an emblem of Summer, ‘‘ pride of the Summer, garden queen.” By making careful selections of species and rearing hybrids, varieties deservedly called Per- petual have been obtained, and, so far as cold countries are concerned, roses can be got now at any season. Of all plants grown in Ceylon for the sake of their flowers, as in other coun- tries, none have gained so much admira- tion as the rose. It has been rightly said that a garden without roses is a misnomer. But how many there are in this country who, possessing the material, do not set about in the right way of doing things. By tar the most effective way of growing roses is to have them distributed through every part of . the garden. The rose is propagated by seeds, cut- tings, layers and suckers (in the case of plants on their own roots), and by bud- ding and grafting. Seed-sowing is only had recourse to with a view of obtaining improved varieties. Layering is per- formed by simply bending the shoot or shoots, desired to root down to the ground, cutting the same half way [JANUARY, 1909. through longitudinally and pegging it down at that point, so that the wounded surface shall come in contact with the sandy soil, watering in dry weather to keep the soil moist. After it has rooted effect separation witha clean cut. Budding and grafting are the modus operandi generally followed at the per- petuation of the rose and many choice trees and shrubs as well. These methods, however, had better be left to expert growers, and we will proceed to the UNIVERSAL SYSTEM OF PROPAGATION. There is no difficulty in raising one’s own roses from cuttings. The cutting should be prepared by clipping off side shoots, but do not remove the leaves; six or eight inches is long enough for a cutting ; see that it is cut off straight at the base just below aknot or bud, or left as it has been slipped off the branch taken off with a heel, that is with a little of the old ripened wood attached. The rose grows vigorously in most kinds of soil. Good ordinary garden soil will produce the rose large enough, but to grow it into perfection abed should be previously prepared. The rose does best in a light free soil, a little fresh, amended from time to time with some well- decomposed manure. A calcareous soil is especially recommended. Delicate varieties do best in fertile, sandy soils, and in peat earth. The dog rose grows vigorously in stiff earth. For nearly all roses, however, the soil can scarcely be too rich. The plants delight in a stiff loam liberally incorporated with manure, and no excellencies of variety, climate, or culture can compensate for the absence of this indispensable resideratum. Where the natural soil is light and sandy, the whole bed should be removed toa depth of two feet, and replaced with the richest natural fibrous loam at hand, or leaf mould, thoroughly mixed with decomposed dung. The MOST SUITABLE SOIL FOR GROWING ROSES in the ground is that which is called a clay loam, that is, which is neither black soil nor sandy soil. A clay loam is more retentive and does not dryso soon as sandy soil. A sunny position with free wind is desirable; shade and closeness induce a number of fungoid and insect diseases. Thorough preparation of the soil with manure is desirable however suitable the soil itself may be. The bed should be clear of the roots of surrounding trees which would impoverish the soil and rob the plants of the nutriment intended for them. This could be guarded against by cutting a deep drain round the beds. After the bed has been prepared open a shallow . ; <> wet 4 January, 1909.] trench, about six inches deep across it and place the cuttings inclined against the steeper side four to five inches apart about which sprinkle some sand, river sand for preference; fill in with the soil and press firmly around the cuttings. Open the next line about seven inches distant and proceed in the same manner, finally passing the watering-can lightly over the bed. Most rose growers prefer pot culture, evidently with the object of being able to move the plants from place to place. But the bloom of pot plants is not always so satisfactory as those from plants grown in the ground. The soil for pot plants should be made up of river soil or alluvial loam, failing this, loamy cabook material, and half manure. If the manure is not old, earthworms and white ants are generated; and old mannre will sometimes contain the larvee of the Chafer Beetle—destructive to rose trees by eating the root. The best planis to spread out the manure and let the birds aud chickens pick up the grubs and sift it before using. Soil, too, sometimes contains the eggs of earth- worms and in that case it should be incinerated. Burning the soil would effect great improvemeut in the case of clay soil, rendering it light and less retentive of moisture. The addition of leaf mould would greatly improve the quality of the potting soil. Itis obviously necessary AFTER PLANTING CUTTINGS that they should be kept shaded and the ground kept moist until they make steady young growth. Cadjans or bamboo tats would do very well for shading; and once the slips have estab- lished a footing the sunshades should be removed. The rose plants, like most other, should be judiciously watered and notswamped. In Nature vegetation makes little progress during incessant rains ; but as soon as the rain ceases and the sun shines, the grass and weeds, and cultivated crops spring up. In _ like manner, if the soil round the rose plants is kept continually damp and the sun and air not allowed to circulate through it, the plants are sure to be unhealthy.— HortTuvs in the Ceylon Independent. THE ROTATION OF CROPS. This is one of the oldest phases of good kitchen gardening, yet it is safe to say that none is less pertectly under- stood by the majority of cultivators. The reasons for this failure on behalf of cultivators to grasp the elements of the rotation of crops need not be sought for in vain, the chief one being that hard- and-fast rules cannot be laid down 75 Miscellaneous. concerning what particular crop shall succeed an existing one, and also that in many cases the grower has only a pactial control over circumstances, and con- sequently is obliged to do the best he can with the soil at his command. At the outset it may be as well to briefly consider the principles which underlie the retation of crops. The chief object with most cultivators in changing crops is to get the best possible results from the soil, the idea being that different classes of plants require different kinds of food for their upbuild- ing; and there is, no doubt, a lot of wisdom insuch acourse, Another point, however, which is frequently overlooked, but which is equally or even more important, is the fact that certain diseases and pests attack certain plants only. and therefore by keeping these plants off the ground for two or three years a disease may beeradicated. Club- root of the Cabbage family is a disease which may be mentioned as an example. As previously stated, a cultivator frequently has to do the best he can under existing circumstances, and often these are such as to render it imperative to overlap crops which would be much better if given entirely fresh ground. There are, however, many gardens wherein it is possible to give the various plots a change of crop each season, and wherever such a course is possible every effort should be made to adopt it. As the question is naturally a very complicated one, only general indications and hints as to carrying out the work can be given; but these, coupled with intelligent application, will, I hope, prove of some use to amateurs and others who have only given the matter a passing thought. Taking the Cabbage family first, it has been proved that all the members thereof require practically the same kinds of food, and in addition, as previously stated, all are subject to attacks of club-root and other diseases and pests which do not attack some other classes of plants; hence it would be unwise to let a crop of Cauliflowers, for example, to be followed by spring gabbages, as the former will. to a great extent, have exhausted the soil of those particular foods needed by the Cabbages, and any disease which might have been present on the first crop would almost certainly make a host of the second. In practice it is found to bea good plan to let deep rooting crops, such as Parsnips, Carrots or Beetroots, follow any of the Cabbage family. Potatoes, again, are another crop which ought not to occupy thesame ground two years running, as they are veritable gluttons so far ag potassic manures are Miscellaneous. concerned, andin practice it has been proved that much better results can be obtained by only cropping a certain plot with potatoes once in three years. Any of the Cabbage family, Peas, Beans or Onions may, with advantage and satety, follow Potatoes, Carrots, Parsnips Beetroots or Celery. Generally speak- ing, Beans should not follow Peas nor vice versa, and this applies to any kinds which are closely related or belong to the same family, hence Tomatoes should not follow Potatoes. The same general remarks apply to flowers, and any Sweet Pea enthusiast, for instance, will avoid growing his favourites on the same soil two years running if he possibly can. In gardens where rotation is impossible of course the food difficulty is overcome to a great extent by judicious manuring, but the question of disease or insect attack can be only thoroughly dealt with by keeping a_ particular plot free from a crop that is likely to be attacked, for several years.—Garden, Vol. LXXIL., No, 1923. September, 1908. SIXTEENTH ANNUAL AGRICUL- TURAL CAMP MEETING FAIR AT CALHOUN, LOUISIANA. ln organizing the several experiment stations of the State of Louisiana some twenty years ago, Governor McEnery and Dr. W. C. Stubbs selected a site in the hills of Ouachita parish in North Louisiana for an experiment station, which should be adapted to the needs of the hill-farmers in contradistinction to those of the alluvial lands and the prairie lands and the pine flat lands. Right from the start the station at Calhoun became one of the most popular in the State and excellent results were at once perceptible. The entire farming community within reasonable reach was affected by the station’s influence along educational lines in improved farming, and that good work has been going on ever since. An Agricultural Society was organized, which held monthly meetings, and this brought in hundreds and some- times thousands of visitors to the station. This led in turn to agricultural camp meetings, and finally toa Camp Meeting Fair, the various visitors bring- ing in from their farms specimens of their home products; and now the annual fair on the experiment station grounds at Calhoun has become a permanent feature, and the display of Louisiana products there would satisfy the most sceptical as to the capacity of our State to produce almost any known agri- cultural product, and to produce it, if you please, in the hills of North Louisiana, 76 : [JANUARY, 1909. where the lands are not considered as fertile asthe alluvial lands. Ina test made some years ago of the amount of corn grown comparatively, Governor M. J. Foster was one of the Examiners, and by actual test, measurement of the land and weight of the corn gathered, it was found that the production of corn equalled over a hundred bushels per acre. Of course no such crop is grown generally in the hills of North Louisiana, nor anywhere else in the United States, but it shows what can be done there with intense culture.—Zowisiana Planter and Sugar Manufacturer, Vol. XXXXL., No. 13, September, 1908. AN AGRICULTURAL COLLEGE FOR BENGAL. The new Agricultural College at Sa- baur, of which Sir Andrew Fraser laid the foundation-stone recently, is an undertaking which ought torouse the utmost enthusiasm throughout Bengal. Itis almost the first step towards the establishment of genuine technical edu- cation in this Province. that is, education which applies the results of scientific research to a great staple industry, and which enables those engaged in that industry to do their work scientifically. When the College is completed, Agricul- ture, which is the chief industry of Bengal, will begin to receive upon an adequate scale the benefits of modern science. Hitherto, though agricultural training has not been wholly neglected, the effcrts made in that direction have been tentative and have been rewarded with indifferent success. As Mr. Gour- lay mentioned in his admirable sketzh of the course of events which has led to the establishment of a College, officers of the Provincial Service were sent to Ciren- cester to be trained, and later instruc- tion in agricultural subjects was givenat Sibpur. But the results were not satis- factory and the Province gained little except, perhaps, the services of the late Mr. N. G. Mukerji. Agriculture in Bengal may. therefore, be said to be now atthe opening of a new era. No pains have been spared to secure a site for the new College where it will be easily accessible, and where land will be available on which as many as _ possible of the principal crops of the Province can be experimentally cultivated, These conditions are fulfilled at Sabaur. As for the College itself, it isclear from Mr, Gourlay’s lucid description that every need of the agricultural student has been carefully anticipated. If thechoice of the staff is equally felicitous, Bengal ee eee eee ee ee “st Qe. € 2> te a : = JANUARY, 1909.] will have an ideal institution, and we hope that Mr. Gourlay may be as fortu- nate in this respect as in others. He will, of course, realise that while high scientific attainments are desirable quali- fications, as is equally necessary that “the professors should be capable teachers, endowed with sympathy and with the gift of winning the confidence of their students. —Ep. C.0.] TAPPING YOUNG RUBBER: AND MANURING OF COCONUTS. Dec. 9th. DeaR Sir,—I was interested to read Dr. Willis’s letter giving his views on what is young rubber. 1 would not putthe limit for tapping age as high as the Director does; 7 years, of fair average growth, is old enough for trees to have excellent rubber, and Magazine of the Ceylon Agricultural Society. 83 But, my point Dr. Willis fails to take up, viz., that his approval of tapping young trees is being used to uphold the tapping of sapling rubbers, 3 years old, which is detrimental to the interests of our industry. Messrs. Lee Hedges & Co. are quite in their rights to make use of Dr, Willis’s approval of their system, but he should not allow it to be used unless strictly as he meant it. While writing, I may also allude to another point. The Director, as Editor of The Tropical Agriculturist, has stated that there is practically nothing new to write about coco- nut cultivation! May I give him a suggestion? Tell us about coconut manuring; the literature on that pointis not exhaustive, I was only recently discussing the matter witha friend, and our discussion on the right methods of manuring coconuts would have made an_inter- esting article. But your space is limited.— Yours truly, 7 HERRING BONES. LATEST ON COCONUT PLANTING. The veteran Mr. W. H. Wright of Mirigama now &8 years of age, whose coconut property is a model of its kind and who usually picks an average of 110,000 to 115,000 nuts per month, told us some days ago he is only picking 50,000 per month at present ; and that crops are short all over the island. At Veyangoda the dessica- ting mills have had a temporary cessation of work for want of ‘nuts, sellers preferring to sell the copra at present prices. Mr. Wright picks twelve crops a year: six small ones from November to April, and six larger from May to October.__He has just now some fine shows of blossom on his Brazil Nut and English (eating) Chestnut trees, promising fruit before long. Matara, Telijjawila, Dec. 17th. Dear Sir,—The information about coconuts from Mirigama is interesting. Short crops seem to be universal, but I think there was an im- provement this year compared to the crops in 1906. Twelve crops a year are not known in this district—six being the usual number, of which those in May and July are the biggest. They are about three times the number plucked in the first and last cropsof the year. There are signs of good crops in 1909, due, of course, to the very favourable weather we have been having.— Yours faithfully, JAS. A. WICKREMERATNE. II. Marawila, Dec. 16th. Dear §1R,—The November number of the Tropical Agriculturist reminds me of the old . issues before it degenerated into a rubber jour- nal, There are in it many valuable articles which I commend to the cluse study of coco- nut planters. I refer to the very valuable and practical articles on pages 457-469. The statement, ‘‘It is a well-known fact that a soil on which plants are growing, loses much more water by evaporation than does a bare soil,” reminded me very forcibly of wy valued friend the late William Jardine, who consis- tently asserted that coconut estates will be all the better for being free of grass and herbage, Of course, this is not practicable, as cattle are an esseptial of coconut estates. But this can with advantage be carried out on new clearings, . where absence of a good pasturage will not attract cattle as greatlyas now. What has Mr. Carruthers to say to this? Some of the coconut estates that suffered greatly from the drought had a thick carpet of rank hrold growing on them. If this had been clean weeded, the soil would have bene- fited greatly by the stirring it would have received, however slight it might have been, and the trees, from the mulch of grass which could have been placed in a circle round them. The Government should have printed in the vernaculars the article on ‘‘ Leaf manuring in South Canara” and circulated broadcast all the island over. Perhaps it is not so necessary in the Tamil-speaking Northern and Eastern Provinces as in the other provinces. As far as my observation has gone, in those provinces the careful and intelligent cultivation one notices amongst the ryots in Southern India, is prac- tised by their Tamil brethren with whom they are closely allied. No vegetable matter, no garden sweepings, no cadjans from the roofs and fences is allowed to go to waste or is burnt. Everything goes to the manure heap, and eventually to the fields. The Sinhalese goiya never cdloes that. He has always dirt in the wrong place. Agricultural Instructors can be use- fully employed travelling about the country and giving plain, practical lectures on paddy culti- vation. Mr Milne, in the article on ‘* Conser- vation of soil moisture,” has a good word to say for the native plough. It must be understood that the Indian plough is a far more effec- tive implement than the Sinhalese plough. Both are _ practically ‘‘cultivators,” but the former, being broader, does more econo- mical work. ae S Tw OR oS =) oe pee ee! ba i KB fat oO Oe ® oO og 2.98 ral 3.8 xe) M°E ~'s 4 ae ms on oS Hs 2.

Mr Tait writes :—‘t The few plants we have here are makiug good growth, having reached a height of 12 feet and a girth of 7 inches, at 3 feet from the ground, at nine months old ; from all accounts this seems a fair growth.” This certainly seems satisfactory considering the peculiar nature of the Christmas Island soil. The whole island consists of three raised coral-reefs rising from sea level to about 1,100 feet altitude. Over this coral rock lies a layer of phosphate of alumina which is of some depth near the settlement. During the dry season, the country gets very dry and owing to the nature of the rock the water sinks through till it ar- rives at the volcanic rock which forms the base of the island at sea level. In such a peculiar soil and climate it is almost surprising that anything grows well, but the whole island is forested with large trees; and vegetables, limes, papaya, and other fruit trees grow well on the rich brown soil near the settlement. Para rubber has been planted as well as ceara, but it is probable that the latter will prove the most suitable. H. N.

TEA NOTES. ‘Mrxico as A TRA-Growrne Country.—With the object of securing reliable information as to the possibilities of agricultural development in Mexico, the Government of that country com- missioned a foreign expert to investigate agri- cultural conditions in various tropical and sub- tropical countries. According to the latest re port of the British Consul-General at Mexico City, this expert has recently returned, and now advises the Government to establish a Mexican Department of Agriculture. He urges that Mexico has special advantages for the growing of tea, cacao, rice and fruit of many kinds. Tue Disposat or Tea Prunines.—In referring recently to the views of Messrs. Joseph Fraser and Bamber, Dr. Willis and Mr. Petch on the disposal of tea prunings—whether by burying or burning—we alluded to the last-named as being inclined (at any rate 18 months ago) to support burying, except where a field is subject to root disease. We are, however, reminded by one who has followed the Govern- ment Mycologist’s work closely that we would be wide of the mark if we assumed that Mr. Petch believes in burying prunings under any circumstances. We certainly did not assume this, for his paper of May 1907 was very strong against burying where root disease existed ; he also pointed out the difficulties often ex- perienced in securing rapid decay of prunings buried in holes. Mr. Petch has, we hear, rather been devoting himself to urging the burning of them for the last four years and holds there is as yet no evidence whatever in favour of burying: that, in fact, there is scarcely a set of figures dealing with any cultivation in the Island which will bear five minutes’ examination: and that until Mr. Joseph Fraser submits his figures to criticism, they must scientifically be regarded as non-existent! The Experiment station Committee, we believe, have not always found figures reliable facts to go upon; and what passes for experiment in tropical agriculture has before this been proved to be futile imitation. We trust, however, that Mr. Joseph Fraser may have something to say on the subject ere next Pitakande meeting comes along. INDIAN TEA ASSOCIATION. (Meeting at Calcutta on Dec. 22.) Mosguriro Buicur. In connection with the pamphlet recently published by Mr Antram on Mosquito Blight, a letter of 17th December from Messrs Shaw Wallace & Co. was read. They urged the im- portance of joint action being at once taken by Proprietors to deal with the blight in view of the danger that, if remedial measures are de- layed, it may increase to an alarming extent. They emphasised the point made by Mr Antram in regard to the necessity for thorough satura- tion of the bush in spraying, and expressed the opinion that the Committee should impress on Proprietors that spraying should be pursued with more ‘vigour and perseverance than hitherto, and that every precaution should be taken to ensure thoroughness, But 103 even spraying to this* extent would not, in their viow, be sufficient, unless the blocks of tea treated were absolutely isolated: and it was with this in mind that they suggested that if headway against the blight were to be made, joint measures inthe affected districts would be imperative. As they pointed out, it would be hopeless to carry out protective measures, however complete, in any one garden, if the surrounding gardens took no steps and re- mained a recruiting ground for fresh infection. ‘They considered that members should be cir- cularised with a view to inducing them to com- bine in the matter.—The points raised by Messrs. Shaw Wallace & Co. were discussed at length by the Committee who were in com- plete agreement as to the desirability of ener- getic combined action being taken on the lines indicated. The only question was as to how far planters would undertake the expense of spray- ing areas not obviously suffering from the blight.—Asa preliminary step it was suggested that some group of gardens in ove of the attected districts might be approached with a view to get them to combine and take the most thorough measures—especially in the matter of spraying the whole area of their tea—for one or two seasons. If this could be arranged and the method were found to be effective, the Com- mittee would be enabled to recommend a similar policy to all members of the Association with much more confidence. Before, however, taking any steps towards having the idea put in force, it was decided to send to the two Branches and to the Dooars Planters’ Association copies of Messrs Shaw Wallace & Co’s letter explaining to them the Committee’s views and asking their opinions on the feasibility of such a scheme as that suggested. Messrs Shaw Wallace & Co. were to be thanked for their letter and to be in- formed of the action taken, MONEY FOR THE EAST INDIES. Easier to get than for the W. I. ‘“‘Theobroma,” writing to the ‘‘ Standard,” says:—‘‘Speaking at a dinner given at the recent Rubber Exhibition, Sir Henry Blake observed that ‘it seemed much more difficult to get money in London for the West Indies than for the Kast.’ This is undoubtedly the case, for, whereas HARDLY A WEEK PASSES WITHOUT SOME IMPORTANT PLANTING COMPANY being successfully floated in connection with Ceylon, the Malay States, or the Dutch East Indies, he would be a bold man who relied on public support for a similar undertaking in the Antilles or British Guiana. Probaobly the vicis- situdes of the sugar industry are largely respon- sible tor this caution on the part of capitalists, but in many of the islands this product is only of secondary importance, while in others it is ractically non-existent. I would suggest the ormation of a committee to investigate and de- termine the causes of the financial disability under which the West Indies labour, whether political, administrative, economic, geographi- cal, climatic, or racial, and to correct any erro- neous ideas which may exist in the popular mind as to their productive capabilities.”—J/. and C. Mail, Dec, 25. 104 The Supplement to the Tropical Agriculturist BRAZIL PRODUCTION OF COGOA. Rio de Janeiro, Nov. 23.—Cocoa is one of Brazil’s staple export products, and represents for the State of Bahia what coffee does for Sao Paulo. Its production is steadily increasing, and, although no official or private statistics re- cord the growth of the internal consumption of cocoa, this is to a considerable extent confirmed by the increased inter-state trade and the erec- tion of new chocolate factories during the past tew years. The State of Para ranks second in the production of cocoa, followed by Amazonas and Pernambuco, but the output of both these States is small when compared with that of Bahia, and atthe same time very irregular. In 1902 the production of cocoa in Bahia was 16,197,000 kilos, and since then it has steadily increased, reaching in 1906 a total of 22,914,000 kilos. On the other hand, the production in Para has gradually fallen from 4,372,000 kilos in 1903 to 1,752,000 kilos in 1606. In Amazonas and Pernambuco production has been erratic. In the former State the total in 1908 was 587,000 kilos, in the following year it rose to over a million kilos, but in 1906 it fell to 357,000 — kilos. Pernambuco, which in 1903 only pro- duced 15,000 kilos, was credited with a pro- duction of 114,000 kilos in 1905. In the fol- lowing year, however, the total production de- creased vy more than 50 per cent. EXPORTS AND PRICES. Official statistics show the following export movement during the past five years :— Kilos. Value. 1903 At 20,899,643 ofa £1,012, 224 1904 50 23,160,028 at 1,095,535 1905 ‘ie 21,090,088 Es 1,039,535 1906 ae 25,135,307 ' 1,386,441 1907 ve 24,897,249 AG 2,186,265 48,794,498 4,880,000 f 53,674,498lb, = nearly 500,000 ewt. in 1907. Notwithstanding the smaller clearances in 1907 when compared with those of the previous year, it will be noticed that in value they show a large increase, which is due entirely to the sharp advance in prices last year. According to official records, the current price of Bahia cocoa in 1905 was Rs. $585 per kilo; in 1906, Rs. $587; and in 1997, Rs. 1 $056. The average price of cocoa in 1907, as compared with that for 1906, shows the extraordinary increase of Rs. $469, equivalent to 79-90 per cent. France was at one time the largest purchaser of Brazilian cocoa, but in 1906 she surrendered that distinction to the United States, with Germany second. In 1903 exports to France reached a total of 8,294,000 kilos, but since then they have shown a steady falling off, and in 1906 the total had declined to 5,283,000 kilos. Hx- orts to the United States have increased from 5,263,000 kilos in 1903 to 8,894,000 kilos in 1906, while shipments to Germany rose from 3, 122,000 kilos in 1903 to 7,190,000 kilos in 1906. Exports to Great Britain in 1903 totalled 2,177,000 kilos ; in 1904, 2,071,000 kilos ; in 1905, 1,250,000 kilos ; and in 1906, 2,020,000 kilos. During the first quarter of the current year exports of cocoa amounted to 9,276,043 kilos, which is an increase of 4,127,434 kilos (80°17 per cent) on the corresponding period of last yoar. The average price of Bahia cocoa during the first quarter of 1907 is officially registered as $912 reis per kilo, and for the same period this year as $903. PRospKcrs OF THE INDUSTRY. The prospects for this product are, on the whole, encouraging, because consumption is steadily growing and keeping pace with the in- creased production. So far, its commercial development has only been fostered by private enterprise, but in view of the proposed coffee propaganda scheme by the States of Sao Paulo, Rio de Janeiro, and Minas Geraes, fostered by the Federal Government, it would be well for the Government of Bahia to take similar mea- sures to advertise its principal export product. —London Tmes, Dec. 18. THE SMYRNA FIG IN WEST AUSTRALIA. In August last the Department of Agriculture coramunicated with the Commissioner of Horti- culture, California, with a view of making ar- rangements for the introduction of the Caprifine insect of the Smyrna fig. Information has just been received from Mr Ahrhorn, Deputy-Com- missioner, San Francisco, that such arrange- ments have now been made, that he will himself attend tothe shipments on the Californian side and that he will do everything to make them a success. These insects are expected to arrive in the course of the summer, and they will be for- warded to the experimental station at Hamel, where a plantation of both Capri and Smyrna figs was established a few years ago. These trees are now bearing, and ready for the insects. The communication received from California further states that the Blastophaga, which is the name of the insect, was some time ago sent to Mr Lounsbury, Government Entomologist, Cape of Good Hope, and was successfully established. Mr Lounsbury also writes to the department that he will gladly supply insects as soon as pos- sible. The Smyrna fig has a world-wide reputa- tion, but, unfortunately, it has the peculiarity of dropping before maturity unless previously ferti- lised by the insect referred to, which winters inside the Capri fig.—Westralian paper, Dec. 5. SINGAPORE’S INCREASING TRADE IN COPRA. In reviewing the trade of Singapore for the past year the Straits Times (Dec. 31) states that the exports of copra continue to furnish satis- factory returns, again showing an enormous advance over previous years, and establishing a record for at least the last half of a decade. There is an increase of some 90,000 piculs shipped to Great Britain and to the Continent of Europe, the United Kingdom receiving something like 63,000 piculs more than in 1907, and the Continent of Hurope importing about 30,000 piculs over the quantity received last year. During 1903, only 5,041 piculs of copra were exported from Singapore to Great Britain, and 581,251 piculsto Europe, while during the year just closing the figures will be about 9u,000 and 85,000, respectively. de PASSIFLORA EDULIS.

XXXII, COLOMBO, FEBRUARY 15tn, 1909, Improvement of Agriculture in Ceylon. As we are leaving the colony in the middle of February, and shall be away for a year, we have thought it well to put down some of the opinions at which we have arrived upon this question, and to complete the symposium by a paper by Mr. Schrader, which appeared in the ‘‘ Independent,” and which is worthy of eareful consideration. While away we hope to visit Agricul- tural Colleges, Experiment Stations, etc.. in Egypt, Italy, Austria, Germany, Britain, the United States, and Canada, and may be able to write occasional articles upon them for the T. A. Incase of anyone wishing to write as regards any subject they may desire enquired into, anaddress which will always find us will be—Gonville and Caius College, Cambridge. We hope also, while on leave, to find time to write the bulk of an elementary treatise upon Nature Study, and the outlines of Agricultural practice, for use in Ceylon Schools. ee Agriculture in Ceylon and its Improvement, By J. C. WILLIS. Ceylon agriculture may be sharply marked off into two classes—estate agriculture and peasant agriculture. There are great differences between these in efficiency and result, and one is liable hastily to generalise, and say that it is all owing to the superior industry and intelligence of the Huro- who manage the bulk of the former. That this is not entirely the explanation, however much _ truth there may be in it, may be seen by omitting the European altogether and comparing the native capitalist or estate agriculture with that of the villager. peans 106 The difference is decidedly more marked than in the countries of Hurope or America, where the small agricul- turist can often hold his own very well by co-operation, against the big one, without having to do as in Ceylon, live on his own products. To get at the real explanation, we must analyse the whole subject. Before progressive agriculture, 2. e,, agriculture on other lines than ‘‘ grow what you want, and consume all you grow,” can go on, there must be satisfactory con- ditions as regards what we may call the preliminaries to agriculture, The chief of these are land, climate, soil, drainage, irrigation, cultivation, crops, transport, capital and education. Now land is plentiful enough, and usually easily obtained or available in Ceylon, and the climate is nowhere unsuitable to the growth of crops, when once the best crops have been discovered. The soil is generally good enough, and drainage and irrigation are sufficiently attended to. Crops are plentiful, nearly all of any value either existing in the island from ancient times, or having been introduced by the Botanic Gardens in the last 70 years. There remain then for consideration transport, capital, and education, Now the provision of transport facilities has for very many years been regarded as a eardinal point in British colonial policy; in fact it has been expressed in the form that the first element of civilisation is roads, the second roads. and the third more roads. Education also has been liberally provided, and with the extension of School Garden work the necessary agricultural bias is being given. Already, in districts where there are such gardens, one sees many new products or types of cultivation, and on enquiry usually. finds that they owe their origin to the School Gardens, Later on, a more definite agricultural teaching will be required in the higher schools, but for the present the school garden is enough. There remains, then, practically un- touched, simply the provision of capital, and it is inthis that the great difference between the capitalist ‘“‘ planter ”—be he European or native—and the villager, lies. The latter has steadily gone down to a very low agricultural level—if in- deed he ever were above it—and has no capital at his back. Now, any agricul- tural enterprise requires some_ capital, for the land must be prepared and the crops given time to ripen. If the culti- vator have no capital, he must have ‘ yecourse to the local moneylender, and from him borrow seed, or advances to cover the period of ,waiting, or what ff [FEBRUARY, 1909. not, or he must sell the crop before it is ripe, of course at a great discount. In actual fact, in about 80 different places in which we have enquired, the usual rate of interest quoted has been 50 per cent. The lowest was 40 per cent. and the highest 75 per cent., but as the interest was generally collected with the principal, long before the lapse of a year, these rates are really higher. It is idle to gird at the moneylender for such rates. His business is to get what he can, and when the villager can only give such scanty security, he must pay high interest to indemnify the lender for the risk. Were it easily possible to lend at lower rates, one would oxpery to hear of its occurrence some- imes. So long as the villager is thus help- lessly in the grasp of the moneylender, so long can he do practically nothing in the direction of agricultural progress, however willing he may happen to be. When we add to this the general apathy and inefficiency he displays, and what, for want of a more accurate term, we must call his indolence, it may be readily seen that agricultural progress among the peasantry of Ceylon is a thing to be- hoped for, but not to be expected till the clutch of the usurer is relaxed, and then but slowly. To endeavour to improve local agri- culture, other than capitalist agriculture, without taking the subject in proper logical order, is to beat the air. One man introduces good European ploughs. Without capital the peasant cannot afford such tools, while at the same time, they make too violent a step forward to be applicable. They cut through the plough-pan of the paddy field, and let the water out. Another man introduces a new vegetable or other crop. Is the villager to sacrifice crops, already yield- ing a return, to experiment with some- thing untried? He cannot doso with- out more capital. A third man proposes to teach agriculture in the village schools. Whereare the trained teachers, and how is the trained boy to apply his knowledge unless he has money? Ifhe bas money, and succeeds, his success simply goes to emphasise the difference already existing between capitalist and villager. Practically every improvemeutin agri- culture demands money at the start, though it may prove very profitable later, and itis but rarely that it yields a profit that will pay the Ceylon money- lenders’ interest, We may roughly represent the present, and the possible, state of affairs by the following diagram :— Frervary, 1909.] | 107 level 4 of capitalist agriculture level 3 of existing peasant agri- culture in Hurope, level 2 below which real ‘‘agri- cultural” progress is impossible, level 1 A A of existing peasant agri- culture in Ceylon, A Provision of land, &c, irrigation drainage crops transport capital education B Careful study of crops—new or improved—on Experiment Stations, with a view to making out their suitability to Ceylon, profitableness, &c, Ditto tools, to gradually improve native implements. Ditto methods, to gradually improve native methods of cultiva- : tion, manuring, harvesting, preparation, prevention of disease, &c, Ditto cattle, to gradually improve native breeds, Improved and more agricultural education, 1 Agricultural teaching by field demonstration. And so on, Given all of A, coming in at level 1, it may be raised to 2, at which the other's will begin to come in as shown. All A should go together, similarly all B. ' 108 [FEBRUABY, 1909. Until the provision of all the items A has been attended to, village agriculture in Ceylon must remain at the low level 1. Given these, asthe people get out of the clutches of the moneylender, it will rise to 2, and then improvement in agri- culture, properly so called, begins. This improvement must be of the most gradual kind, and every step must be carefully tested by thorough experi- ments before being recommended for adoption, Improvement of cattle must go hand in hand with improvement of the tools they are to use, and with improve- ment of their food supply, and so on. This must suffice as a brief indication of what we are convinced, after 12 years’ study, is the logical order in which to attend to the improvement of Ceylon agriculture. Loans to Native Agriculturists. Given that loans of money are to he made, whether by Government or Agri- cultural Co-operative Societies, to vil- lage agriculturists, the question comes up of how best to manage it, and how to obtain good security, forin the case at any rate of a Government loan, it would be unsound finance to advance against no security. The essential features of the Raiffeisen loan schemes (by means of local Agri- cultural Co-operative Societies )—which have been so wonderfully successful in Europe, and are now extending in India— are that the lending by any given soci- ety is confined to the village where that society is located, that it is managed by a local committee who understand as thoroughly as possible the financial status and reliability of each borrower, and that the liability is unlimited, so that in the event of loss, it falls upon each member of the society in propor- tion to his holding. The question then is—Can these prin- ciples be applied to local conditions? We are decidedly of opinion that the strict localisation of loans should be carried out. Let for each small district a local committee be formed, with the Govern- ment Agent as Chairman, and the local headman as deputy chairman, and let this committee be responsible for the making of the loans, which must of course be absolutely confined to their own district. The next item is the recovery of the debt owed by the villagers. We would suggestfor this the revival of the old levy of 10 % of the crop. This is a tax the villager well understands, and there would be no grievance in its revival, if done soon, while the outcry that might be raised against its being reinstituted asa tax would fall to the ground if it were simply revived for repayment of loans, Butas the least that could use- . WILLIS. fully be advanced to the villager would be the value of his seed paddy—say Rs. 2 to Rs. 4.50 per acre—it is doubtful if the 10 % tax on the crop, which in many districts is barely ten-fold, would repay the loan with interest at say 123 %, which must always be charged. We would suggest a 15 % return or even more in most cases, and where this proved to be much too much, some might be returned to the cultivator. By this means the villager should in a few years get sofar rid of the load of usury that at present oppresses him, that he might be able to consider the question of actual ‘‘agricultural” im- provement. Probably only a few at first would in any case be willing to try improved crops, tools, manures, or cattle; but let these succeed and others would follow. Next as regards security for the debt. We would suggest, as has already been done by Mahawalatenne R. M., that the greater headmen, as deputy chairmen of the local committees, give security for the amount to beadvanced. This they will very commonly beable todo, and if they are at first debarred from advancing more than the value of the seed paddy, while the 10% levy is pledged for their repayment, there should be no difficulty about this. The 10 %, 12} % or other levy would obviously not bring in exactly the amount necessary for repayment, but the figure should be fixed at the nearest 23 % above what is necessary; e.g., if 13 % were considered needful, repayment should be by a 15 % tax. In this way the local committee would come into the possession of funds of their own, and these might be again lentin any way that seemed best to them, adhering strictly to the principle of local loans and unlimited liability, and at an interest of say 123%. As the Government is about to lend for paddy FEBRUARY, 1909.] cultivation only, these loans might be for other or new crops (é.g., to start sweet potato growing in the district), for better tools(e.g., asociety might purchase a disc harrow or other tool and lend it out to its members), forsupply of manure (by purchasing manure from Colombo and advancing it to members, to be repaid at crop time), for provision of stud bulls, cocks, pigs, etc., for sale of local produce in the Colombo or Kandy markets, or for other purposes. But the important thing at the commence- mentis to get the villager. gradually free of the exactions of the money-lender, as has been explained in another place. 109 This must be done gradually, or a new class, that of distressed money- lenders, will come upon the scene, and we would suggest beginning with the advance of seed paddy only, against the security of the headmen, through local committees, the money to_be_ repaid by a definite tax in kind upon the p roduce. We would confine loans at first strictly to the ordinary villager, and decline to advance any money to the richer people, unless at so high arate of in- terest that they could not profitably lend it out again. Agriculture in the North-Central Province. By J. ©. WU£LLIs. In this paper we are, of course, merely taking the North-Central Province as a type of the low-lying irrigable country of Ceylon, which stretches from Ham- bantota round the mountains to the north to Chilaw, and these remarks will apply to most of it. This country is occupied by a very small population (leaving the coastal districts of Batticaloa, Jaffna, and Chi- law out of consideration ), probably not much over 200,000 in all, though the area is over 13,000 square miles. or more than half of the island. Now, in the olden days of the Sinhalese monarchy, this was the populous and wealthy part of Ceylon, while the mountain zone and the west—now the home of the great tea, coconut, cacao, rubber, and other industries—were a poverty- stricken and neglected region. Now, there is no reason why there should not to-day be a great population, and large industries, in this now desert- ed land. The important thing is to analyse the position carefully, and to set to work in the proper logical order. _ At present the North-Central Province ‘is largely occupied by a good-humour- ed, fairly honest, but lazy Kandyan population. By the opening of the irri- gation works they have been practically freed of the great amount of disease which formerly devastated the country, and have become, for villagers, fairly prosperous. Looked at agriculturally, they have afew conspicuous faults. They waste a great »mount of water upon their rice crops, which they grow mainly in the dry season with tank water. They cul- tivate other things mainly on chenas. They do not grow more paddy than they want, and often leave the fields bare for long periods, Now the last-named of these faults is one of character and temperament, and cannot be easily altered, but the two former depend mainly on the agri- cultural conditions of the country. A comparison of any other of the outlying thinly populated districts will show the same faults in operation. There is evidently some general cause forthem. They depend, in general, upon the fact that in all such districts one finds, uvon the whole, less capable and less successful agriculturists, who live as muchas they can upon the natural capital of the country. This natural capital in Ceylon is simply land or soil, water, and forest, The native of the North-Central Pro- vinee, like any one else, has of course taken the best land for his rice crops, and to that there cannot be the slight- est objection. He then, however, pro- ceeds to grow his other crops largely upon chenas, and for this he uses the best land he can find, and ruthlessly sacri- fices the other item of capital—forest. After a couple of chena crops the land is left to lie fallow in scrub fora good many years before the process can be repeated, There is neither need nor space to go into details in a paper like this, which is simply- giving a general sketch without argument. To turn now to more detail about the other two faults mentioned, and first the fact that rice is grown mainly with tank water in the dry weather. The Jaffna man who visits the North- Central Province is at once surprised by this; he, without tanks, and in a drier country, must grow during the North East rains. The ordinary unthinking man puts it down to dislike on the part of the villager to being out in the rain or to some such cause. Experiment, 110 {Frprvary, 1909. conducted at Maha-iluppalama, in the North-Central Province, have shown the true reason. Village rice sown broad- east in a field simply supplied with rain water has grown well enough, but has become a mass of weeds, which cannot be removed without great trouble and damage to the crop. Whereas, if the land is completely softened by the rains, and well ploughed, tnen left to soak, and kept always soaked, weeds do not get much chance. This is the real explanation. To improve on the present methods sowing in the rains is not enough. The land must be tilled before the rains, and the crop must be transplanted in rows, so that weeding between can be carried out. This means greater expenditure, in keeping the land tilled all the year round, in transplant- ing, andin weeding. This means capital, which the villager has not got, so has to live upon the natural capital of the country. Now turn tothe chena. The land is cleared of trees, up to acertain size and burnt off. Before the weeds begin to grow, the crop is thickly broadcasted on, and gives a good return on the fresh forest land. But the weeds grow, and it only occasionally happens that the villager can afford, from his indolence, enough labour to partially clear for a second crop, which of course is not so good as the first. The land is then allow- ed to grow up in scrub, which keeps down the small weeds, and after a few years can be again cleared at far less eost than weeding would involve, while it has had the advantage of a kird of fallow. Land which natives and Kuropeans alike said was only fit for chena is now being continuously cultivated at Maha- iluppalama and _ yielding good crops. But without capital, which is the un- derlying secret of success there, the villager of the North-Central Province is as helpless asa baby to do anything but chena, as he is helpless to grow rice with the rains, and he must not be blamed for his present methods. Another point about chena is the effect on the soil. To keep the natural capital of the soil unimpaired, either rotation, manuring, or chena must be practised, and as a capital is wanted for the two former (as has already been indicated) the last is the only possible resource. We have now to consider the problem of what is to be done to get_the inhabi- tants of the North-Central Province out of this state of things. If left as they are, progress will be as it has always been—very slow. With the opening up of the country by transport facilities, capitalists will gradually be attracted into it, but the villager willnot progress. It therefore becomes a question whether attention is to be devoted wholly to the capitalist, or whether the villager, and people like him, are to be helped also, and whether they are to be directly helped, or assisted to help themselves. The latter is what we personally vote for, but this question is one for the Government, and has only to do with agriculture in that its solution is an essential to progress in the latter.“ In the old Sinhalese days, it is probable that the villager was at least upon as low a level as at present, and the kings helped them by compelling them to make tanks, which greatly increased the natural capital of the country, by making water available at any time, instead of only in the last few months of the year. Whiletheoretically, no doubt, it would be better to aid the villagers already existing in the North-Central Province to supply themselves with capital, im- PIONS their agriculture, and take up the alance of the available land, in practice this would take centuries, and is too long to wait. The villager should be settled upon his own land, and a sufficient area reserved about him, which he will at first of necessity chena, but which he will, as he gets more free of the money-lender, gra- dually be able to lay down to permanent cultivation. Now,there is little doubt that he is so indolent that he would prefer to go on indefinitely upon the present lines, and compulsion must be brought to bear upon him. We would suggest that, provided he has been sup- plied with the means of getting cheap capital, the chena area be reduced by 25%, say, every sixth year, till he has only 25% left. He will thus be compelled to lay down, the land to permanent crop- ‘ping. We would attach the chena area to the village as a whole as common land, and stipulate that part of it have the trees sufficiently thinned out to cause it to form good pasturage, and of course © make the area large enough to allow of room for other crops when the necessary - proportion of the 25% remainder was given to pasturage, In this way the chena difficulty might be gradually got over. At present the villager must chena, but the land will stand per- manent cropping. It must be rememhered that for annual crops—which are much better suited to the small capitalist than perennials, such as rubber or tea or cacao—the chena land must be irrigable. Pasture, on the other hand, need not he so, FEBRUARY, 1909.) We would suggest, as he becomes more free of money difficulties, gradually curtailing the amount of water allowed to the villager for his rice land, and the upplication of some at least of the saving to his ‘‘common.” So long as_ the present rate of water consumption is allowed, so long willit be impossible to Open up any seriously larger extent of country. Water must be available before land can be opened. Experiments should be set on foot to determine the minimum water that can be allowed to the villager. They should then be limited, at first to say 25 % more than that, and the amount gradually decreased, thus setting more water free for other land. The local villagers being few in num- bers, lazy, and improvident, other people should also be induced to settle, and here comes 1n another very import- ant consideration. The newcomers should be settled in entire villages of one race or caste, and by the mixing of peoples thus brought about, the general standard of living will be raised, and some variety introduced into the local agriculture. At the same time, among the villages thus formed, blocks of land should be reserved for capitalists, and land in them only sold in large pieces. In this way the villager will have object- lessons at his door, and the capitalist village labour. Every village thus formed should be given some common land, part of which should be devoted to pasturage, part to crops that can be marketed elsewhere, i.e-, in general the crops that can be 11, sold to the local capitalist estates; and a definite water supply should be allotted to the common. Communal tools might also be obtained by co-operation among the villagers, or by a 10 % tax on the produce. In laying out the villages, they must be divided by road reservations, in which, as_ traffic increases, actual roads can be made, though at first mere clear- ing of the track (pin-para) would suffice. This is very important. Transport faci- lities are one of the indispensable preli- Minaries to progressive agriculture. There remains then the attracting of capitalists. Just as with the villagers, the first to come are often small ones crowded out of other parts of the country. To attract these is something, but more rapid progress will be made if larger can be also got to come. The pre- liminaries of land, labour, transport, and, above all, guaranteed water supply, must be carefully attended to, and capital will then be attracted to grow rubber, coconuts, cotton, and other things. Under some of the tanks the land should be saleable only in large blocks and no small holders allowed. This will serve as a brief indication of some of the lines upon which we would propose to work, and a careful consideration of the whole question during this year will be time well spent. The general lines we have been laying down are developed at greater length in a book upon “ Agriculture in the Tro- pics,” to appear within the next few months, and which those interested in tropical agriculture may find of interest to study. The Teaching of Agriculture and how to Teach the People. AN OBJECT-LESSON FROM AUSTRALIA. In my article on “The Improvement of Cattle in Ceylon,” I made the follow- ing statement: ‘‘ There is no doubt that ocular demonstration is of far greater importance than preaching, especially when dealing with the ignorant masses. This must be taken full advantage of in driving out the prejudices and lax methods of the psople.” This shail be my text for this article, and I feel certain that it is the only way of starting to improve the obsolete and ignorant methods of the people. We know that the most approved methods of the present day of teaching infants is by means of object-lessons. In the same manner the only way to teach the grown up ignorant agricultural infants is by the same methods. NowI will forma short resumé, as farasI know, cf what has been done in the past. A School of Agriculture was started in Colombo under the able guidance of a graduate of an English Agricultural College, but it was a failure--why? In the first place the country (was not ripe enough for an = institution of that nature, the right stamp of students were not attracted, and most of those that came there came to receive a 112 cheap education, and on leaving the institution they turned to every walk of life—except agriculture, We know that once the son of a village ‘“‘gamarala” dons a pair of trousers and a coat, he does not care for his village life. In the second Place Colombo or any city isin no way adapted for an Agricultural school. Rural work ° MUST BE CARRIED ON AMID RURAL SURROUNDINGS, where there will be sufficient land for the actual carrying out of agricultural operations in every branch, the students playing the principal part. The late Colombo School of Agriculture did not apparently pertain to teach practical agriculture, except in the form of cultivating a few vegetable plots, which was absolutely valueless. The next thing was agricultural education in the form of School Gardens. They are no doubt excellent in their way and for the object in view, but not of sufficient weight by them- selves, to reach the mass of agricul- turists. Then we had the starting of the Agricultural Society by Sir Henry Blake, our late Governor. The Society publishes a very good journal, holds monthly meetings at which are read numbers of valuable papers, etc., and also have around it numbers of branch societies doing similar work, but the main object, that of reaching the agri- cultural masses, is lost sight of. Now we are coming into a new era under our progressive and practical Governor who, no doubt, willdo his best to give us something that will reach the masses. In starting agricultural instruction and development in CeylonI do not think wecan do better than be guided by what has been done in other countries. As I am able to speak with some authority on WHAT HAS BEEN DONE IN AUSTRALIA, having had the opportunity to spend ten years there, all the time actively engaged in agricultural pursuits, I will refer to what has been done there. The agricultural masses of Australia were at one time ignorant, as far as modern scientific agriculture was _ concerned. They ploughed and sowed the same crops year after year on the same land, and could not understand why the land would not produce the same quantity of grain per acre asit did years back. They used no modern labour-saving appliances. They could not understand that rotation of crops, green fallowing, artificial manuring, the proper treat- ment and application of farm-yard manure, etc., would be beneficial and would be their salvation, They looked [FEBRUARY, 1909. down on scientific cultivation which they called ‘“‘new fangled ideas.” The Government had a hard task to perform, but they went aboutitin avery prac- tical way. They started establishing experimental farms right in the heart of great agricultural centres. These farms were Zhuge object-lessons, Land similar to that worked by the farmers was cultivated under ‘“‘new fangled ideas.” Everybody, of course, was curious to see the result, while at the same time being certain that the whole thing would be a failure. By and by, as time went on, some of them started visiting the Government farms, and were shown round by the managers who took the opportunity of explaining the why and wherefore of things being done, told them of the number of bushels per acre the lust wheat crop yielded, ex- plained the methods adopted in making farmyard manure, the amount of labour saved by the use of certain implements, etc., etc. The visitors went back and pondered over WHAT THEY HAD SEEN AND HEARD and naturally talked about it to their brother-farmers, who, in their turn, visited the farms, and so on, and so on. Later on the majority came to the con- clusion that there was something in these ‘‘new-fangled ideas” and went for help and advice to the managers which, of course, was most readily given, and gradually modern methods began to be adopted, the farmers finding that by their adoption the crops were doubled, and that the use of labour-saving ap- pliances put more money into their pockets. The experimental farms then started taking in afew students, as the farmers wished their sons to receive modern training, and, of course, the scope of these farms only permitted practical agriculture being taught. As things went on the time became ripe for the stablishment of Agricultural Colleges where a student could receive both scientific and practical training. In the State of Victoria, where I spent most of my time, the first College started was the Dookie Agricultural College, where I graduated. This College was, first of all, an experimental farm, then an experi- mental farm with a few students, and lastly an _ Agricultural College. It had attached to it 4,700 acres of land, and only received, while I attended it, forty students. Since then the number of students has beer doubled. At this institution every kind of tarm- ing was carried on and taught, the course being two years. A student in case of failure to pass examinations was allowed a further year, bit at the expiration of that period had to leave. The Pat Nk =—5 8 FEBRUARY, 1909. STUDENTS WHERE DIVIDED INTO FOUR CLASSES, two junior and two senior—one junior and one senior being out working on the farm every day, while the other two were attending lectures, the subjects comprising the breeding of horses, cattle, sheep, and pigs, irrigation, drainage, arboriculture, ensilage-making, the grow- ing of serial crops and their man- agement, Chemistry, Botany, Geology, Zoology, Entomology, English, Natural Philosophy, Book-keeping, Surveying, Horticulture, Viticulture, Apiculture, and Olive-oil making. Four professors lectured on these subjects, while there was a separate outdoor staff to teach the practical work. The outdoor working day consisted of eight hours, the stu- dents actively carrying out all the dif- ferent farm operations, the staff only teaching and seeing that the work was properly done. Every season about 500 acres were put under serial crops and about 60 under silage crops; vineyard work was carried on, and wine made from 80 acres; dariying was carried on, about twenty-five cows being milked daily, the milk being turned into butter and cheese; olive oil was made; orchards were attended to; about 4,000 sheep were shorn; pig breeding was carried on, and poultry’ received atten- tion. Large experimental plots were worked. Black+smithing and carpentery were taught, all repairs to machinery being done on the place. Other farm operations too numerous to mention were earried on. All this work was done by the students, and done well, and the farm paid its way. When a student finished his course and went out into the country, he was a power in the land, he was a thorough master of his profession. Later on Victoria found it necessary to open another College. The other States started on similar lines, and all of them have now large flourishing AGRICULTURAL COLLEGES AND EXPERIMENTAL FARMS, yearly sending out young men to teach and to work for the country’s good and their own. It was by ocular demonstra- tion, by means of huge object lessons, that Australia the great Agricultural continent started teaching her sons modern, scientific agriculture. And I think my readers will agree with me that this is the only way it can be done in Ceylon. Ofcourse we don’t want 4,700 acres of land; 100 acres with some paddy Jand would suffice for our experimental farms. Too much stress cannot be laid on the choice of the men who are to manage and work these places, as on them and on them alone depends the 13 118 success of the undertaking. Personality, ability, education, a thorough mastery of practical work, and men not ashamed to take off their coats and show the people how certain operations have to be done, all these essentials must be embodied in those who are to have in their hands the future destinies of the improvement of agriculture in the Island. Soon we shall find, as Australia did, that the masses who are by nature agriculturists will take interest in the object lessons, and give the new methods atrial. Once they do that and find it paying they will naturally enlarge their scope of operation, and will, in a short time, come to the conclusion that there is money in new methods. They will then want their sons taught the new methods, and, by and by, when these sons are turned out of the experimental farms and work THE LAND OF THEIR FOREFATHERS, they will find more money coming in. Their training will have taught them to work to the very best advantage, and when these young men in_ their turn have sons of their own old enough to receive agricultural training, %.e., about 16 years of age, during which time they received a good elementary education, then will be the time for Ceylon to open her first agricultural school, and in time turn out, as Australia is doing, hundreds of young men yearly, who will ‘‘ go out into the land and make it bring forth fruit abundantly.” THE SCOPE OF EXPERIMENTAL FARMS, In the foregoing article I suggested that “100 acres of high land with some paddy land would suffice for our experi- mental farms.” The question will arise, “What is to be done on these lands’? In other words, in what form are these object-lessons to be placed before the grown up agricultral infants of Ceylon ? Itis important that these farms should be worked on business-like principles, ~ Everything done should be within the scope of those who are to be taught, and induced to adopt the new methods. The produce must be commodity, and must show profit. Otherwise the farms would be useless. They must be worked with economy. A strict account of ex- penditure should be kept, so that the actual balance after the sales can be made public. A great object-lesson is to show the people how much money these new methods will put into their pockets. The following is a LIST OF THE IMPLEMENTS, ETC., a marketable 114 necessary for each farm :— One “forest devil” or stump extractor, three ploughs for high land, three ploughs for paddy land, two sets of harrows, one roller, six hay forks, one paddy-field_ leveller, one hay knife, one paddy-threshing machine, six long- handled shovels, three scythes, two double bullock carts, one ‘planet junior * single cultivator and three pairs heavy draft bulls. THE QUESTION OF PADDY CULTIVATION —how to grow more paddy than is now done—should be brought home to the villager. It is a question that appeals to most people when the greatly increased cost of rice has to be considered. It is a question that the planters would like to see solved, as it touches them sorely when they have to retail rice to coolies at less than cost. In fact, it is a national question and worthy of the attention of Government. We have the land, and it only requires proper cultivation. to bring about the necessary results. The Government is yearly spending large sums of money on irrigation works. Of what use are irrigation schemes if the greatest question of all—that of teaching the people to make the land productive— is left untouched? The paddy land of the farm should be entirely fenced in and judiciously subdivided so as to en- able cattle to be run on the stubble without interfering with other cultivat- ed portions. The plough must be light, but able to turn soil to at least a depth of four inches. It must have two handles and one pole. It is absolutely impos- sible to do good work, i.e., cutting and turning over every inch of the soil with straight furrows at an even depth with even the English-made ploughs sold in Colombo with one handle and a pole, asthe pole makes the plough far too sensitive to every movement by the cattle, and with one handle it is im- possible to steer it. The ploughs should have the usual beam as used for horses, to which should be hooked ona chain to take the place of the pole, and to the end of the chain the yoke. In these matters I am nottheorising but speak from personal experience. The ordi- nary native plough is, of course, out of question as it does not plough but scratches the surface. The first process of preparing land for paddy is to repair the bunds and clean out the channels, for which work I would introduce the long-handled shovel mentioned in my list of implements to take the place of the Ceylon mamotie. The shovel does the work sooner and better, and is a far handier tool to use. The fields should then be inundated and the water allow- ed tostand a sufficient length of time ‘Se =a eae eal 41 | ce) ple ee (FEBRUARY, 1909. to killthe weeds. After this the water should be turned into other fields, and when the land is sufficiently dry, plough- ing should commence. The ploughman should turn upthe soil toa depth of about four inches. If necessary it might be cross ploughed. The land should next be levelled and the seeds sown. I am not a_ believer in the transplanting process, advocated by many, but itis entirely a question of “will it pay?” If it does, certainly do so. But I believe, if the two-handed system of sowing is adopted, as is done in sowing’ wheat in other countries, transplanting will not be necessary. This and other matters the experimental farms should very soon solve beyond question. Once the seed is sown and until harvest time judicious irrigation where possible is about all that is necessary. In the matter of harvesting scythes can be very well used. A man can do four times as much work with a scythe as can be done by the small sickle now used, except on land where water is lying and it would not be judicious to wet the heads. The introduction of hay forks, and a threshing machine will, with the greatest deal of economy, and in the shortest time, have the paddy in bags ready for market. It is out of the question for every man who culti- vates paddy to own a_ threshing machine. But, as is done in other coun- tries, once these machines are found to pay, travelling machines will do the workatasmallcharge. There are other matters which will have to be attended to as they turn up—judicious manuring, bare fallowing, and, if possible, the growing of other crops, forage, etc. DRY GRAIN CULTIVATION. For this and other work to be detailed later, one hundred acres should be felled and burnt off after securing sufficient timber for building and fencing purposes. The land should be fenced and sub- divided into paddocks of twenty acres. All the stumps should be extracted. This is a most difficult and expensive operation. It can, however, be done cheaply and expeditiously and quicker with the ‘‘ forest devil” mentioned in my list of implements. The subdivision of land is necessary for running cattle on the stubble or feeding off green fallow cecops, etc. The villager usually cultivates some dry grainonchenalands. The land is lightly hoed and the seed scattered. The result naturally is very poor. He also has a belief that the land can only be cultivated for about three seasons. after which he allows it to grow back into jungle, What he has to be taught is that dry grain can be grown, and grown with excellent results on the same De TA ‘id Vy ree ani . , Fesruary, 1909.) land year after year, if he cultivates the land properly and follows out a system of rotation of crops, with judicious green manuring, ete. The land on the farm must be ploughed to a depth of at least four or five inches. The plough used for the work must be of a little heavier type than that used on wet, clayey paddy land. After ploughing the harrow is put on which will stir, pulverise and level the land thereby making a good seed- bed. The roller will then follow. With regard to the effect upon the crop of pressing the soil about the stems and roots of the plants, all who are familiar with gardening works know. The plant cannot grow well if the soil does not support it in a fixed_ position, while alternating rainy and dry weather will draw the soil away and destroy the close relation between soil and plant necessary for the process of vegetation. lhe roller counteracts this and establishes close contact between soil and stem and roots. The _ seed is now sown and covered. Once the plants have established themselves and attained a certain height, the harrow is put over the growing crop, This loosens the soil thereby breaking up the capillary tubes and minimising evaporation. The har- vesting could be done in two ways either with a reaping machine orascythe. I would not suggest the reaper as it would be very injudicious with the object in view to introduce anything that the villager cannot buy or improvise. So far the only expensive implement he will have to procure is the plough. A serviceable set of harrows can be turned out by a village blacksmith, and a_ very good roller can be made out of a log of wood. Ploughs should be sold to vil- lagers at cost price to be paid for by in- stalments. As years goonand the people become more prosperous and have learnt the first lessons of the utility of modern implements, then can be introduced seed drills, reaping machines, disc harrows, threshing machines, etc. CATTLE, The experimental farms can be run in conjunction with the ‘‘Stock Farm” sug- gested in my article on ‘‘ The Improve- ment of Cattle in Ceylon.”—vide page 57 of last issue. A certain number of cattle are necessary for economic purposes. There is always the stub- ble to be utilised and crops vnder green fallow to be fed off. It is neces- sary to have draft power available. The raising of cattle would also show the people the economy and profits of mixed tarming. PIGS AND PIG BREEDING. We all know the difficulty of procur- ing a good piece of pork, so much so, that 115 wherever a good pig is secured for butchering, it is specially advertised in the papers. Why should not good and cheap pork be always available ? At present, except by a few individuals, pig breeding in any systematic way is unknown. Two pairs of pigs, one of Berkshire and the other a Poland China, would suffice for each farm. circular holes with a diameter of from 6 feet to8 feet and from one foot to 18 inches deep. Some think it neces- sary to sprinkle salt on the surface after planting, others salt and ashes, etc., etc. In weeding some believe in clean weeding ; others let the weeds grow up and weed once a year; yet others adopt a middle course, between the two. Some bury the weeds with the fallen coconut leaves in large trenches between the rows of trees ; others burn the leaves, weed, etc., and sprinkle the ashes round the trees ; while some mix theashes with manure, ete, ete. In cultivation some turn up the entire soil; others turn the soil round the tree to an extent of 6 ft. from the base leaving a space of one foot at the base; others again leave 18 inches and two feet at the base and turn up 7 feet, 8 feet, ete. In manuring with cattle manure some trench round the trees and tie cattle throughout the year, turning the manure into the soil and replacing Oils and Fats.| the earth taken away by trenching, when able, i.e-, when there is rain. Others don’t trench. They tie theeattle and turn the soil when able. Some tie two head of cattle fora week; others for lesser or Icnger periods, ete. There is also a diversity of ways in the application of artificial manure. Some do not believe in it at all; some spread the manure on the surface and turn the soil, the space left at the base of the tree varying from one foot to two feet, ete., and turning up from 8 to 9 ft. ete. Some trench round the tree and apply the manure. They TURN THE SOIL TO A MAMOTIE DEPTH, and replace the soil that has been removed; others leave two feet at the base and dig a trench a foot deep and a foot wide, put the manure into it, and cover. Someuse forks, others ply the mamotie, and so on. There is also a diversity of opinion and method in sup- porting bunches, In picking the crops some use long bamboos with a knife attached; others insist that the men should climb the trees jand pick the nuts, etc. In turning the nuts into copra even some large proprietors entrust thousands of rupees worth of produce to badly constructed and the most inflammable of drying sheds, storing the dried material in stores of a primitive and inflammable nature. Surely each and all of these methods cannot be right and yet wrong. I will now give AN ACCOUNT OF THE METHODS I HAVE ADOPTED and my reasons for doing so,andI only hope others will do the same for mutual benefit. I by no means contend that my methods are theright ones. Hight years ago I took charge of a coconut property of over 600 acres, without any previous experience in coconut planting, trusting to my scientific training, knowledge and experience in agriculture and horticul- ture gained in Australia, and also hop- ing to learn the methods adopted by others. But, to my great surprise, I found that there was no fixed principle or method employed. No two planters even under similar conditions of soil and climate adopted the same method. There is no doubt that all cultivators of the coconut and other palms are to a great extent moving as it were in the dark, as there is no scientific data to work on, no records of research as a guidance. All that can be done at present is toapply scientific data_estab- lished for general agricultural and horti- cultural purposes in other countries, combined with what experience itself has taught us. But what I contend is that even this little has not been done in any systematic form as far as the coconut tree is concerned. 126 (FEBRUARY, 1909. NURSERIES.

At the end there will be wanting 2 ft. x 1 ft. depth of soil, which is replaced by the first spadefuls of soil that were thrown out. I adopt this method as all young plants require a good free depth of soil to enable the young roots to easily make their way in search of food. For, as J stated in a previous communication, a soil well tilled makes the dormant plant food, by means of nitrification, and by other chemical changes that take place by its exposure to atmospheric influences, more available and in a soluble form to be easily taken up by the young plants. If the young plants receive any check it retards their growth, and once dwarfed they never entirely recover. For plant- ing I chose the best round nuts from trees about 380 years old, the nuts being from those bunches that are ripe at the time of picking. I plant the nuts stalk end up, leaving about half aninch out of the ground and a space of 18 inches between them. At every third row I allow a pathway 2 ft. 6 inches wide for the purposes of subsequent weeding and watering. I now cover all the seed beds with ordinary dry coconut leaves to prevent the direct rays of the sun acting on the part of the nut above the surface and also as a mulch for conserving moisture. lalso keep the place weeded, and water it at intervals during the dry months. The distance of 18 inches between the nuts [ consider necessary as feeding room for the young plants, as well as for a free circulation of air so necessary for the well-being of all growing and living things. Watering Cl consider necessary to make the plant food soluble and to prevent any re- tarding growth. The results I find highly satisfactory. PLANTING. In laying down the plants in the field I place them 27 ft. apart as being some- thing betwixt and between the various distances generally adopted. I also eon- cluded from personal observation that it gave sufficient feeding ground for the roots, as well’'as air and light so necesSary for vegetation. The coconut holes are 4 ft. square at the surface, graduating down to 3 ft. square at the bottom. The depth of the hole 8 ft. For the purpose of getting through the re oh ti Ae An aaa Ba Ros 2 Si ae eat eh Reervary, 1909.) 12! work fast and being accurate, I make a number of light frames of the top and bottom sizes, which enable the men to mark out in the first place a proper square that would be at right angles to the holes that have been dug, and the ones to be dug, and the 3ft, frames would guide them as to the accuracy of the bottom. In low lying land the holes are cut to various depths, from 1 ft. 2 ft. 6 inches, and in some instances the nuts are planted on the surface. This land I subsequently drained, throwing the earth up and thereby raising the land where the trees were planted. The drains at the same time drew away all superfiuous moisture. THE YOUNG PLANTS are carefully dug out of the nursery taking care that only the best plants are taken up, and any broken’ or damaged roots trimmed. One _ foot of surface soil is, returned to the 3 feet deep holes, and in it the young plant is placed and staked, taking care that the soil round the plant is firmly tramped down, leaving just the top of the nut showing. The soil I was dealing with was asandy loam with a good free gravelly sub-soil—there being in most parts of the land 3 to 4 feet of good surface soil. There is no doubt that one must be guided by his soil and sub-soil as to the depth of planting. As for example, if the sub-soil is one of cold clay which is as a rule impervious to water, and is not physically fit for planting, if it has tobe planted, surface planting is the only way, backed up by a thorough system of drainage. WEEDING. On the subject of eradicating weeds I was taught (Ist) not to allow the weeds to go toseed, (2) tostudy the nature of the plant, (3) not to allow any plant_to breathe too long, (4) to weed clean. No. 1 needs no explanation. No. 2 is very important as some plants wili die when cus at surface level, while to others surface cutting will act as a pruning and will make them grow better; others again grow from cutting. So each has to be treated according to its nature. As regards No.3 the leaves being the breathing pores of the tree the constant cutting down after the weed was grown to about 5 inches, weakens the consti- tution of the plant and in times it dies out. This has been done with great success in Australia, where it was found impracticable to root out certain weeds on very large areas, No. 4 is equally important, as by careless weeding one cannot eradicate weeds, as the plants left will run to seed and the seed become plants before that portion has its turn again. I applied these methods according [Oils and Fats. to the nature of the weed [ had to deal, with the result that what was a very weedy estate became practically clean. I do not approve of burying the coconut leaves, etc., in trenches in the middle of the rows, as I consider that the expense would be greater than the _ benefits received. Dry vegetable matter as a rule does not contain any valuable plant food except potash. I chop up the leaves with mamoties and burn them with the weeds in suitable heaps, and scatter the ashes around so that the potash would percolate into the soil by the rain. CULTIVATION. I was taught, and experience has proved, that intense culture with deep cultivation is necessary for successful fruit growing, for the reason, (1) that the feeding roots could travel easily without resistance in search of food; (2) that it meant-anaccess of airso neces- sary for nitrification and for other chemical changes that would take place by atmospheric influences, etc, by which means the dormant plant food becomes available ; (8) that it meant the reserva- tion of moisture by means of breaking up the capillary tubes in the soil and thereby minimising evaporation; (4) that it prevented the washing away of plant food as the rain would penetrate into the ground instead of running away. Ifound that I could not carry out all these principles on the coconut estate, so [I set to work to adopt as much of them as possible. I found that the soil had been turned round the trees in certain portions, tothe extent of 5 feet leaving one foot at the base ofeach. For the first wet. season I continued this system, as my labour conditions, etc, would not permit anything more. The next season I left 18 inches at the base of the tree, and turned the soil 7 ft. round thetree. I later on increased it to 8and 9ft., my object being to continue increasing so that ultimately the two circles of the opposite trees would meet, and the entire FEEDING GROUND BETWEEN THE TREES be cultivated, The cost of turning soil 9 ft. leaving 18 inches at the base was a little over 2 cents per trees as a cooly could do 16 trees a day, wages at 388 cents per day. I imported a splendid double farrow plough from Australia which I worked with a team of four buffaloes, but asthe buffaloes required too many men to drive, and «as they could not be worked during the hotter parts of the day, I hired an elephant paying Rs. 5 per day, and, feed- ing it on coconut leaves, I found that with the elephant 1 could plough four acresa day. The heavier soils require Oils and Fats.) 128 more cultivation than those of a sandy- nature. In the same way sandy soils would be injured by too much cultivation. MANURING. 1 found the practice in existence of tying during the nights two head of cattle a week toeach tree, ina basin 5 ft. round the tree. This was done right through the year, and when the wet weather came on, the soil in the basin was turned up amamotie depth, and the soil which had been originally in the basin was put back. There is adiversity of opinion among the highest agricul- tural authorities as t> whether fresh dung is better than decomposed farm- yard manure. High authorities dis- agreeing, each having good reasons for and against, I came to the coaclusion that both systems are good if properly adopted. So during the wet weather, and as long as the soil was moist enough fortucning, I tied two head of cattle a week toa tree, and atthe end of that period turned in the manure after dis- tributing it in the basin, and returned the soil taken away by ‘‘basining.” At the same time I turned up another 8 ft. of soil outside this radius. But tying the cattle to trees during the dry weather and waiting for the wec weather to turn the manure into the soil, did not seem to me at all correct, for by that time all the valuable properties, or most of them in the manure had evaporated, and all that remained was a hard mass more fit for fuel than manure, which when buried would not decompose for years. BY THE SYSTEM OF BASINING also a large number of trees would receive material injury, for in the fisrt place a great number of feeding roots are cut away which in itself gives a shock to the tree. Then the cattle tramping in the basin for a week solidifies the soil, thereby increasing evaporation and also preventing the below ground feed- ing roots having easy access in search of food. I constructed some MANURE PITS WITH A ROOF in different parts of the estate, so that the material would be as close as possible to the land to be manured. I tied two head of cattle to trees in the neighbourhood of the pit, and every third dayI had the dung collected by women and thrown into the pit, taking the precaution to sprinkle a sufficient quantity of kainit to prevent the loss of nitrogen. [ changed about using the trees, as farasI could, taking care not to get too far from the pit. This was done with the object of allowing the liquid manure in the form of urine to benefit more than one lot of trees. I also carted to the pit any straw or other waste material that would decompose [FEBRUARY, 190d. and form manure. When the wet weather came I carted the manure from the pit to the trees to be manured, spread five ordinary garden baskets full round each tree, and turned the soil to a distance of 9ft. I used cattle manure once, and the next time artificial for reasons given in my article on “ Artificial and Farmyard Manure, ete.” In the application of artificial manure I had to be guided by the amount of money I was allowed to spend for manuring, so Iecould only apply the two principal necessities—phosphorie acid in the form of bone dust, and nitrogen in the form of castor cake, at the rate of 3 lbs. of the former to 6 of the latter. I got the two manures separately as it is cheaper that way than buying the mixed, The cooly measured the two and mixed them up before use. I spread the mixture on the surface over a 6 ft. radius leaving one inch at the base of the tree and turned itin. Then 1 turned over another 3 ft. outside this radius without manure. Later on, I sprinkled as much ashes as I could possibly collect around each tree to supply the necessary potash. I give below an ACCOUNT OF THE ACTUAL COST, ect., which might be of interest to some. Rs. Cs.

At a later period I was able toapply a more complete manure consisting of the following mixture in the proportion of :— 200 lbs. rape cake. 150 ,, fish manure. 200 ,, bone phosphate. 50 ,, sulphate of potash. 300 ,, kainit. Applying 10 Ibs. of the above mixture to a tree and working it out with actual cost of manure and labour, etc., it comes to :— Cost per trees 41 cts. acre at 70 trees, Rs. 28°70. 39 29 ii ie ae FEBRUARY, 1909. | 129 The reason for applying a large per- centage of kainit was to supply sodium chloride (common salt) to the soil. This I think of great importance to lands away from the sea. Kainit contains over 30 per cent. of salt. A cooly could easily manure twelve trees per day, 7.e., measuring and mixing the manure, spreading, turning in the manure toa6 feet radius, and turning unother 3 feet outside this radius; this means, wages being at 33 cents per day, that each tree costs a little less than 8 cents. Turning the sods competely over thereby burying the grass and manure, I consider very important. This is easily done except on estates of a sandy nature, by removing the first lot of sods and turning the second lot into the trench, working from the base of the tree to the outer. I also found that two or three coolies turning the soil at one tree simultaneously could do better work, and the work does not seem so tedious, as one cooly working at each tree by himself. PLANTING VACANCIES. I had to do this ona large scale, as on taking a census of the estate I discovered that there were about 3,500 vacancies, and as [ had over 200 head of cattle to protect the plants from, I adopteda method that.had been carried on before ; that of using husks stacked up around, asafence. I found this an excellent plan, as it not only acts as a fence but as a mulch in conserving moisture. I carted five cart-loads of husks to every vacancy and had them stacked round the holes when convenient. When the wet weather came I planted. Results were astonishing, and the method is to be highly recommended ; only care must be taken that the stacking is well done, starting with a good broad base and gradually thinning. Otherwise, the first bull that comes along and tries to get at a dainty morsel growing inside, knocks down half the fenceand makes endless work. PICKING, I do not believe in picking by means of a long bamboo witha knife attached, as the trees do not get cleaned, and the pickers are liable to cut down immature bunches, which is undoubtedly a serious loss. I persisted in the climbing process which, although a little more expensive, is I consider cheap and safe in the long run. Iconsider nothing requires such careful supervision as the getting of the right bunches picked, as after all, the labour and expenses on anestate is for the purposes of getting the best fruits at harvest. 15 PROPPING BUNCHES, This I found absolutely necessary, as certain young trees have long fruit stalks, and these stalks being weak could not support the weight of the bunches, A little experience and _ observation taught me that the propping requires careful attention, forif itis not done carefully and thoroughly more harm than good would be the result. Luckily, I had a large reserve jungle to procure my props from, and so had the pick and choice of the best sticks and was not limited to number. My experience has taught me that the props used should be of the strongest willowy timber; that the ends should be carefully pointed ; that the props should not be longer than is absolutely necessary for the particular bunch and the situation of the bunch; that the bunch should only be very slightly raised; that the point of the prop should be very securely driven into the trunk of the tree, and that the FORK OF THE PROP SHOULD BE INSERTED INTO THE CENTRE OF THE BUNCH and not at theend. The cutting, point- ing and propping cost for 11,160 props is Rs. 74°51, the work being done by trained Tamil coolies under direct super- vision. Trees from 20 to 25 years old seemed to getover this propping stage. I should think that in selecting nuts for the nursery, if they were chosen from trees that always.had short tough fruiz stalks, we would be able to reproduce ‘chips of the old block” and propping becomes a thing of the past. Propping becomes a serious question on some estates, as props of any kind are getting scarcer and searcer, and prices higher and the sources are getting less and further away. It would be a great boon to most planters if some inventive genius would produce a suitably cheap, pliable, imperishable substitute to the jungle forked-stick now used, I read in an English magazine that railway rails were being manufactured out of com pressed paper; if that is possible, it should make excellent props with the addition of a steel point. DRYING. It seems a great pity that no better process has been introduced than the present method of smoking, Thesystem is scientifically incorrect and risky, but I suppose, with the usual backwardness of Ceylonese enterprise, it will be a long time yet before we get anything better. I had a great deal of experience in dry- ing apricots, peaches, raisins, pears, plums, ete., which wasentirely dried by the suninaclimate where the average rainfall is 14 in., and the thermometer very often registered 120°in the shade. The fruit was exposed to the sun on Oils and Fatst »Oils and Fats, 130 wooded trays after being subject to the fumes of sulphur during the night. Copra drying is much easier as the nut is not so perishable and does not require such careful handling as fruit. It is, however, very important that the dry- ing ground be large and open, so that the copra gets the direct rays of the sun ‘during the greater part of the day. It is impossible to turn out first-class copra ona small faulty shady ground. Care must be taken not to break even during the best of sunny weather more nuts than the drying shed would hold in case of rain. FAULTILY CONSTRUCTED DRYING SHEDS are an abomination and a_ source of great dissatisfaction. Well con- structed drying sheds should be the first consideration of a proprietor, as other- wise badly dried copra is the unsatis- factory result anda source of dissatis- faction both to the proprietor and superintendent, although unfortunately the latter would more than likely get the blame, although expected to make ‘bricks without straw.” As the saying goes, that the ‘‘ proof of the pudding is the eating of it,” this article would not be complete without giving some idea of the results of my work. I was able in three years to reduce my labour staff from sixty to forty all told, which meant thirty actual labourers, the other ten being watchers, carters, etc. THE NET PROFIT when I took charge was Rs. 9,000 per annum, and four years afterwards it amounted to Rs. 29,000 per annum, after erecting some permanent build- ings, planting 24 acres of new land, and doing other permanent work such as drainage, constructing bridges, and making roads, ete. In CONCLUSION I consider that there are various pro- blems to be solved in connection with this (FEBRUARY, 1909, industry, and as no individual proprietor has either the time or money needed for experimenting purposes, it should be THE DUTY OF GOVERNMENT as isdonein other countries, to carry out expriments and show the people the best methods; for instance, supposing a land under coconuts was a clay loam, what would be the result if the land was yearly ploughed to a depth of 8 to 10 inches, and during the dry months if the soil was constantly kept stirred up by means of a set of disc harrows or other cultivating machines? Expe- rience has proved beyond question in other countries that in planting this process is absolutely necessary, as it bene- fits the trees, thereby greatly increas- ing the yield. But whether it would benefit the coconut tree and make it yield sufficiently to cover the increased cost of cultivation as well as to give an increased surplus, isa question that can only be proved by experiment. Then again ploughing is no doubt better and would be cheaper than hand work if only suitable ploughs with suitable motive power could be procured. Un- fortunately we have neither at present. The ploughs in use at present with one handle and a pole does a half ploughing half scratching business to an uneven depth of not more than 3 to 4 inches, which is practically useless. These ploughs are absolutely faulty in con- struction, and I defy any ploughman to do good work with them, leave alone the ordinary estate cooly. in fact the whole question evolves down to this. Do‘*we get as much as could be possibly got out of the coconut palm, or would better modes of cultiva- tion greatly increase the yields both in quantity and quality ? P. G. SCHRADER. —Ceylon Independent. % Freprvuary, 1909.] 131 FIBRES. COTTON CULTIVATION IN THE KURUNEGALA DISTRICT. By Dr. H. M. FERNANDO, M.D. Dr. Willis has stated that an experi- ence extending over three years is neces- sary to makea definite pronouncement as to the results of cotton cultivation. In this Paper I venture to embody the experience gained in cultivating this product inthe Kurunegala District for five consecutive years. START. A commencement was made in 1903 ona very small scale with Upland cotton, and the indigenous’ variety known as Kidney cottor, which grows so freely asa perennial in village gar- dens. In 1904, with selected seed sent by the Cotton Growing Association, a definite series of experiments on a larger scale was started with the following varieties of cotton :— (a) American Upland. (6) Sea Island. (c) Egyptian Mit-Afiffi. (d) Kidney, About ten acres were devoted to each variety, and the resulting crops were inned and baled by _ hand-machinery forwarded to me by the Cotton Grow- ing Association, to whom the cotton was consigned for sale and report. The results of the sale, although the quantities were not sufficiently large to attract proper competition amongst buyers, were eminently satisfactroy. The Upland and Sea Island varieties fetched higher prices than the average prices of the British cottons grown in America, and the Egyptian cotton was quite equal to the average samples pro- duced in Egypt. THE OBJECT OF THE 1905 EXPERIMENT was to find out which of the varieties of cotton fetching a ready sale in the mar- ket of the world was best suited to the district in which the experiment was conducted. It was also essential to determine the proper season of the year tc commence the planting. _ The Upland variety reaches maturity in the shortest time, requiring about four and a half months only for the crop. The Sea Island needs about five months, whilst Egyptian cotton re- quires about a month longer. In well- drained land all the varieties demand plenty of rain for growth and matur- ation, and an assured period of dry weather to follow to enable the crop to be picked without damage. YIELDs. The Egyptian variety gives the heaviest yield, and the Sea Island the smallest. As the latter fetches the highest prices it was found that it was the most remunergtive to grow. The distribution of rainfall and dry weather obtaining in the district ren- dered it absolutely necessary to plant cotton with the North-east monsoon rains in October and November, and depend on the February-March drought for the crop. These weather conditions precluded the successful cultivation of the Egyptian variety, Since 1905 only Sea Island cotton was cultivated as an annual crop. The land at my disposal consisted of either virgin forest, or chena, gener- ally undulating. Owing to the nature of the land, the number of stumps on the ground, and the fact that cotton formed a catch crop amongst rubber or coconuts, the only attention the cotton received after planting was clean weed- ing. Efficient cultivation of the soil which is essential to the proper growth of cotton was not carried out. Even under such adverse conditions of growth the yield of lint per acre, which varied from 11C to80 pounds in different years, was satisfactory. This yield was ob- tained over an area of about fifty acres each year, and fetched prices varying from 10d. to 1s. per pound. PESTS: THEIR PREVENTION. Every variety of cotton, grown in the wet zone in Ceylon, is inclined to be- come a perennial. This habit of the plant must be systematically checked if success in cotton cultivation isto be secured. After thecropis gathered, the plants should be rooted out, or allowed to be eaten up by cattle or goats. The necessity for this is due to the fact that cotton is highly susceptible to insect pests, and if it is grown asa perennial, the indefinite multiplication of insects, with a permanent food supply at their disposal, will ultimately ruin the culti- vation. Treating cotton as a six months crop every year is the best means of fighting its) insect enemies, In the Kurunegala District at least two kinds of insect pests were met with, The Fibres. eaterpillar which feeds on the leaves is not a very serious menace. It can be effectually and economically kept at bay by theuse of the Paris-Green Spray, consistently applied from the time it makes its first appearance. On the other hand, the insect which destroys the bolls appears during the period that the bolls are formed, and can only be prevented from multiplying indefi- nitely by preventing the cotton plant from assuming a perennial character. CorTrron SUCCESSFUL ROTATION CROP. From the above considerations it will be evident that cotton cultivation may be carried on in Ceylon with profit if planted in flat lands capable of easy cul- tivation as an item in a series of crop rotations. In districts where the rain- fallis sufficient, and its distributions favourable, the crop may be grown as in America and in West Indies without irrigation. Onthe other hand, where irrigation water is available, the most favourable conditions exist for the carrying on of this cultivation—condi- tions simillar to those that prevail in Egypt. I have no hesitation in stating that with proper cultivation and under irrigation a crop of 250 to 300 pounds of lint per acre may easily be gathered with the Sea Island variety, and perhaps 490 pounds or more with the Egyptian cotton, Such acrop at present prices 182 _ [Fervary, 1909. would yield a very handsome profit and one sufficient to attract capital to remote and unopened districts, provid- ed, however, labour is available. JAFFNA A SUITABLE CENTRE, In the Jaffna peninsula, on the other hand, where labour is plentiful, and where the sytem of farming is such that cotton can easily represent an item of ordinary cultivation, this product may be grown with greater success than perhapsin any other part of the Island, Now that tobacco cultivation is no longer profitable, I would suggest that cotton be grown in place of tobacco. Cotton requires less water and infinite- ly less care and attention than tobacco, whilst the present prices promise greater profits. The surface-wells so prominent in the Northern Peninsula are admir- ably suited to the irrigation of cotton. MARKET FOR COTTON. Hitherto considerable difficulty exist- ed in the sale of produce by small farmers, as there were no local buyers for the unginned produce. The pioneer- ing work that has already been done has encouraged the British Cotton Grow- ing Association to set up a local ginning plant through their agents in Colombo, who are prepared to help all growers, however small, to sell their produce at the best market rates. AN = )A ‘Fesrvuary, 1909,) 138 EDIBLE PRODUCTS. COW-PEAS. By Ligeut.-Cou. J. R. Y. GOLDSTEIN. Departmental experience with cow- peas has shown them to be a most pre- carious crop under ordinary field condi- tions. They are most sensitive to Jate frosts, and even a cold day checks them severely. As a commercial crop they are not held in high estimation, although for green manure or fodder they are of great value. Under irrigation in the Goldburn Valley excellent crops have been grown. Last season varieties were supplied to Lieut.-Col. Goldstein, who undertook to test them at the Chelten- ham Convalescent Home for Men. Con- ‘sidering the nature of the soil and the unwonted dryness of the season, the results, as given in the following report, are of value: — It will be remembered that the winter of 1907 was sodry that the subsoil was deprived of its annual wetting, Conse- quently, spring and summer growth was unusually backward, and was further injured by the absence of summer rains, The cow-peas sown late suffered like other vegetation, and there were many gaps in the lines. But, being drought- resistant, the bulk of them came through the dry season satisfactorily. The four varieties supplied were, New Era, lron, Wonderful, and Whip-poor- Will. The parcel of Iron contained peas of two colours, though evidently true to name ; these I separated and sowed in distinct plots to test for ‘any difference, naming them provisionally, ‘‘ White Iron,” and ‘Red Iron.” The result showed the dark to be a fortnight later than the light pea, but the difference may have been accidental and will be tested further. All the peas were sown on 18th October, and they ripened seed in the following order :— WhitelIron 15th Feb., 1908 106 days, New Era ... 21st ,, oe 2g Red Iron ... 24th ,, ried Wiss Bea Wonderful 28th ,, > D1OFe: Whip-poor- Will «. 19th; March, ,, 139. ,; All continued to produce pods until 16th April, when they were ploughed in by mistake, but previous experience in Gippsland goes to show that cow- peas will produce pods until stopped by cold. The pods were gathered weekly and careful records kept. The heaviest gatherings were obtained during the third and fourth weeks in March and the first week in April. White Iron and Red Iron are similar in growth and yield, plants about 20 inches high, ripening seed early, and bearing pods in succession for about three months; pods about 7 inches long, containing 12 to 16 seeds of medium size. Imported seeds are deep brown in colour, some being cream-coloured. New Era, the second earliest, is a low- growing, slender bush with delicate foliage, small pods and seeds ; pods about 6 inches long, thin, containing 12 to 16 seeds, brown in colour and mottled. Wonderful, third in order of ripening, has robust and spreading growth, with strong branches and large leaves, cover- ing the ground quickly; plants about 14 inches high ; pods about 8 inches long, thick, containing 12 to 18 medium-sized peas, flattened at the ends, colour reddish brown. Whip-poor-Will, a late variety, is strong in growth, withan abundance of large foliage; branches spreading and numerous; height about 18 inches; pods about 9 inches long, fleshy, containing 2 to 18 large peas, kidney-shaped, brown mottled. A STRONG PLEA FOR THEIR CULTURE. Cow-Pea plants grow vigorously until they commence bearing, then slowly until April, when they start a second growth, throwing out branches with a running habit, soon forming a densely-matted mass of rich, succulent herbage suitable for fodder, ensilage, or green manure, The plants are specially suitable for making into stack ensilage, which may be done in the paddock where grown, thus reducing labour, bringing ensilage- making within the scope of any small farmer, and thereby inducing that class to adopt the making of ensilage regu- larly. When ploughed under, for green manure, the soft, sappy mass rots very quickly, so that any other crop may be sown almost immediately. It is this quality, of speedily breaking up inthe soil, due to the luxuriance of its second growth, which constitutes much of the value of cow-peas for manurial purposes. It has been claimed for this plant that, under favourable con- ditions, two sowings can be grown successively in one season, which further heightens its value for restoring humus to hungry and worn-out soils, It Edible Products. also gives a heavy dressing of nitrogen to the soil, which benefits the following crop, and even when the plants have been cut for fodder, the remainder, when ploughed under, is much more useful than the dry stubble of any other crop, Cow-peas should be sown as early in spring as possible, but where there is anger from hard frosts, sowings may be delayed until later. They will flourish in all parts of Victoria, from the Murray to the sea, and will succeed in the poorest soils and the driest seasons. In rich soils, they should be sown 2 feet apartin the row, rows 3 feet apart. In ordinary soils the plants may be closer in the row, say 18 inches apart; and in oor soils 12 inches in the row, and 30 inches between rows. American farmers regard cow-peas with much favour and grow them largely for many uses, but green manure is the main purpose. American cattle and sheep Asian well upon the fodder, the plant being rich in albuminoids and carbohydrates. In the household, the green puds are found to be equal to French beans, while the dry peas are used to replace haricot beans for table use. Their long period of bearing—cow- peas podding freely for three or four months during the hottest summer— should commend this plant to our market-gardeners. For seed, cow-peas are very profitable, yielding from 20 to 40 bushels per acre. The retail price here, at present, is about 30s. per bushel, while field peas are about 4s. 6d., with a similar yield of seed. This great difference should give large profits to growers of cow-peas for some consider- able time. But, even were the price to be reduced to that of ordinary peas, the cow-pea would still be the more profit- able crop to grow; its superiority being manifest from its not drying up after its seed has been ripened, and by the value of the second crop of material for fodder or for manure; material, perhaps, of nearly equal money value to that obtained for its previous crop of seed. What greater inducements can Victorian farmers require to make them give cow- peas a trial ? Although this plant is called a pea, the seed isshaped like abean. Botanically, it is closely allied to the Dolichos. It is described under thename of Catiang sinensis, synonym Vigna sinensis. It has been in use for food purposes fora thousand years or so; itis the Chowlee of India, the Tow Cok of China, the Caffre bean of the Cape, and now the Cow-pea of the United States. There are several varieties, with seeds varying widely in shape and colour, white, grey, brown, and black, with many inter- 134 [FEBRUARY, 1909+ mediate shades and markings. It is one of those tropical plants, like maize, which grow well in cool climates and ripen their seeds freely. I am not aware that any extended attention has been directed by scientists to changes of colour in seeds growing under varying conditions, but the changed colours under the present tests are too remarkable to be passed over. All peas pproduced from dark-brown and from reddish seed have come white; there is not onc dark seed in the produce from either Iron or Wonderful. In New Kra, the brown has disappeared, the produce showing a rather pleasing shade of grey ; Whip-poor-Will, a dark seed, has produced’ buff-coloured peas. As it is the red colour which has vanished, the change may possibly be due to the absence of iron from _ the soil. Cheltenham soil is almost entirely composed of a silicious sand containing no iron; but, as most manures contain some iron, the disappearance of red from the colouring of all these peas seems to me to indicate clearly the extreme poverty of the particular soil in which they were grown. It will be interesting to experimeut this season with appli- cations of iron sulphate in different proportions, At any rate, present results are so striking that they should be worth placing on record, not only because they show the impoverished condition of the soil, but also because they go to prove, incontestably, that cow-peas can be depended upon to produce fair crops in poverished and poor sJils, even in very dry summers. I propose to continue tests this year, adding three other varieties, and sowing a month earlier than last season.— Journal of Agriculture, Victoria, 10th November, 1908, Vol. VI. Pt. II. COW-PEAS, SOY-BEANS, VELVET BEANS. With the exception of lucerne, we are unable in this climate to grow any per- manent leguminous crop as a change of feed for pigs. In mixed farming the value of cover crops in replacing the fallow is now being generally conceded. It is neces- sary to differentiate from those used as catch crops and for green manuring. Cover crops check evaporation, pre- vent the soil baking, also the loss of plant-food by excessive rainfall in wash- ing the soil or leaching and they afford green, succulent food for stock. Plants belonging to two groups are available for this purpose. The first are ooh) ih Reames» 5 CL ae Mi 3 ~ ¥ FEBRUARY, 1909. ] 135 those known as the legumes, which possess the specific function of assimil- ating or storing nitrogen in the soil. They include clovers, cow-peas, Canada field peas, vetches, soy beans, velvet beans, lupins, and Beggar weed (Desmo- tium tortuosum), The second group are non-leguminous and embrace rye, wheat, barley, oats, buck-wheat, rape and mustard. The cow-pea is looked upon as the most useful. It forms asucculent, relishable, nutritious forage for sheep, cattle, and pigs during the hot summer months. At that period all other palatable fodders of high protein content are not available and the natural grasses and herbage are dry. Cow-peas as a drought-resisting fodder Stand unrivalled. They have been used in India and other notoriously dry countries for centuries. They have acclimatised well here. The roots of the plant, like that of lucerne, penetrate deeply into the subsoils, in a vigorous fashion searching for plant-food and moisture, and at the same time opening up the subsoils and rendering them porous and available for the storage of moisture and air. The roots attack the stores of phosphoric acid and potash, dissolving them for their own use as well as for subsequent crops. The characteristic nodules of legumes are found freely distributed along the roots, and in these the bacteria are engaged in assimilating atmospheric nitrogen and promoting nitrification ; inert plant-food is made soluble and a source of root nourishment. The roots and stubble are ploughed in with the excreta from the grazing animal. Itis approximately estimated that the former alone give to each acre 24 lb. nitrogen, mostly gathered from the air, and return 6 1b. phosphoric acid and 15 lb. potash, largely drawn from the subsoil, and in a form readily assimil- able by the next crop. The organic matter provides humus and increases the moisture-holding capacity of the soil. Whilst the plant is growing the thick rich spreading foliage covers the ground, arrests evaporation, stops the growth of weeds, and keeps the soil in a loose friable condition. It is anideal cleansing crop and pays its way in furnishing stock fodder, and in addition the soil is enriched with humus, nitrogen, potash and phosphoric acid, fertility is restored, and the land effectively manured for a main crop. In short, to use a familiar farmer's phrase, the land is brought into ‘‘ good heart,” Edible Products. As a food for stock, particularly pigs, during the latter part of summer we have had abundant evidence of its flesh- producing capacity, and, as with lucerne, its power to provide a suitable inter- mixture of lean flesh in bacon and pork. Young pigs three months’ old, when building up frame and tissue, make ex- cellent progress on cow-peas balanced with rye, wheat, barley, potatoes, or maize. Theration can be modified to suit the needs of the animal as it approaches the fattening stages. The foliage of the plant may be utilised for providing green forage, or allowed to ripen suffi- ciently for hay or silage, or the beans can be used as pig-feed. As a fodder the yield per acre varies, and is deter- mined by the variety grown, soil, culti- vation, and climate. At this College quantity has ranged from 4 to 12 tons of green feed per acre. The composition will average as follows :— Water 84 per cent, Dry matter 16 : 4 100 The dry matter contains :— Fat tee a6 ‘4 per cent.

Hern wie Lx os by tie Nutritive ratio 1:3°3 Vari- ation ranges between two distinet classes, cne class being upright in growth, compact, bushy in habit, and without runners; the other producing long, trailing vines, or runners, and spreading well over the soil. The first or bush varieties are noted for their heavy, quick growth and suc. culence. Amongst these the following have proved most successful on this farm—Poona and Chinese Mottled. In hot dry districts, with a sparse rainfall cow-peas take longer to mature. The best sorts are thoseof trailing or recumb- ent habit. They possess a deep root- growth and are better enabled to with- stand drought. The sorts recommended are—Black, New Era, Clay, Whip-poor- Will, and White. It should be remem- Edible Products. bered that cow-peas readily alter their habits in response to local conditions of soil and moisture. The seed-pods range in length from 4 to 16 inches. These, with the seeds, are of all sorts, shapes, and colours. Each sort varies in time of maturing, habit of growth, ripening and other features. It is best to select tested varieties for the main crops and to con- duct tests with new sorts on ‘a’ small scale. The most satisfactory variety subject- ed toaseries of trials here for the past six years is Poona, an upright, bushy plant, of vigorous and dense growth. This was. originally imported by the late Mr. Farrer, from the Department of Agriculture of India. We have had a yield as high as ten tons to the acre from it. Cow-peas revel in heat and sun- light, and will thrive ona wide range of soils; generally they do best on light soils. The light sandy loams at this College have always afforded good re- turns from this plant. The only soil in which it will not respond is that which is constantly wet. In all cases the soil should be deep, well drained and mellow. On impoverished soils the crop is one of the safest and most certain renova- tors. Being a hot-climate plant it is necessarily very susceptible to frost, and planting should not commence until frosty weather has passed. November is usually the month to sow the main crop, although successful crops have often been secured from October sow- ings. Fresh sowings may be continued until February. The soil must be well cultivated and brought into a fine con- dition of tilth. Where manure is re- quired, the best stimulant to rich growth can be secured from an appli- cation of fertilizers affording phosphoric acid and potash. This is supplied by the following :-- Superphosvhate, 200 lb.; Muriate of potash, 100 lb. per acre spread broadcast. In some soils—clay loams—itis found essential to release plant-food by dress- ings of lime at the rate of half to one ton per acre, The hest practice is to sow the cow- peas indrills 2 ft.6in. apart, the seed 6 to 8 inches from each other, and covering with soil about 2 inches. The use of a maize drill fitted with a plate having ¢ inch holes facilitates sowing. Cow-peas germinate quickly on moist, well-prepared soils. The whole crop 186 [FEBRUARY, 1909, grows rapidly and evenly. Shallow cul- tivation should be followed once a month with secuffler or cultivator until the plant is developed. Of late years the practice of sowing climbing varieties of cow-peas with maize or sorghum has been adopted with very goodreturns. The yield peracre, in many instances, has been doubled. For conservation as silage this class of crop is becoming increasingly popular, especi- ally the combination of maize with cow- peas,-seeing the increase of protein by ihe latter asissts to balance the food constituents. In using the crops for hay the best time to cut is when the first pods beign to ripen. Like Red clover it is liable to heat if carted and stacked too early. The cut hay should be left exposed to the sun for a few hours, and then put into cocks for thiity-six to forty-eight hours. Care should be observed in drying not to allow the leaves to become brittle. If the hay be too moist when stacking it is likely to become mouldy. It should be carefully stacked and protected from the weather.

This plant comes from Japan, and of late years has attracted attention as an annual leguminous plant which produces the richest of all beans in protein and fat. It closely resembles the cow-pea, is of bush form, erect, hairy, branching freely and growing to a height of 2 to 5 feet. The seed pods are clustered on the main stems and branches. are 1 to 2 inches long, and contain from 1 to 3 seeds or beans. They give a greater yield of beans than cow-peas. They are not trailing in habit, hence are more easily harvested. They mature early, but last lounger than cow-peas, and afford alonger season for pigs to feed on them. Hither the green forage, hay, or beans should be associ- ated with other foods owing to their richness. In feeding the bean it should not be more than one-fifth of the total ration. As high as ten bushels of beans FEBRUARY, 1909.] to the acre have been harvested here. These are classified as the richest of all natural vegetable foods, and should be used to strengthen the ration in protein. With their aid pigs can then be fed with potatoes, maize, barley, rye, or other starchy foods. As a green forage crop they are highly appreciated by pigs, and afford a more nutritious diet even than cowpeas. The plant can be converted into hay in asimilar way to that of cowpeas. As silage it has been foand most suc- cessful when mixed with twice its weight of green maize. The soy bean requires a good loamy soil well drained, although like the cow- pea it is adapted to a wide range of soils. A deep, firm, well-tilled, moist seed- bed is required here. It should be ploughed to a good depth about the end of July or beginning of August and worked (harrowed and volled) to a fine tilth. Should fertilisers be required, use that recommended for cow-peas. The seed should be sown when all chances of frost are over;as a rule the beginning of October is best when some warmth is in the soil. Sow in drills 2 ft. 6 in. to 3 ft. apart. One plant should be permitted to grow every Ginches. Krom 8 to 10 1b. of seed per acre is needed. Shallow cultivation should follow until the plants are well grown, The quickly maturing plant and pods ripen in from seventy-five to ninety-five days. It is a good drought resister. As a food for pigs, either as beans, green forage, or hay, it has a high repu- tation. The animals fatten quickly, are always thrifty, with strong appetites; the hair and skin acquire a glossy look, and the skin feels as if they were fed on oil meals. VELVET BEAN. So far this leguminous plant has only been grown in an experimental way to test its capacity as a fodder, but suffi- cient data. have been secured to war- rant extended trials for its useas green summer forage, for green manuring, and as a cover crop. Its leading drawback is that it requires along summer for its proper develop- ment, as it is a native of Incia and thrives well in a hot, dry climate. Both plant and bean are useful as fodder tor stock, and pigs relish the food and provide good returns onit. It grows freely on light, sandy land, pro- vided it is fairly well-drained. When moisture is available with summer heat the plant produces enormous yields, Under ordinary conditions it will give a return above the weight of cow-peas 16 18 lod 4 Fdible Products. per acre. The plant grows in a trailing state and produces vinee running from 29 to 30 feet in length; they twine around any obstacle, and are often grown In conjunction with maize. It is a heavy cropper and has been known under favourable conditions to produce thirty tons of green forage per acre. The seed may be sown inthe warm districts in October. The roots go well down into the subsoil ard necessarily require a deeply ploughed soil. The seed should be sown in drills3 ft. 6 in. apart with a space of one foot between each. The best fertiliser is :— Superphosphate . 150 lb. per acre. Sulphate of Potash ... 80 ,, 6 Cultivation should be pursued as long as the plant growth will permit. Owing to the entanged nature of its growth it is difficult to cut for stall green feed- ing or hay. It is therefore best used as a grazing crop, and the pigs should be turned in to eat it off.—Agricultural Gazette of N.S. Wales, Vol. XIX., Part 10, October, 1908. THE CO-OPERATIVE MARKETING OF CITRUS FRUITS. - THE CALIFORNIA E'RUIT-GROWERS’ EXCHANGE, The Honourable the Minister for Agriculture is in receipt of a letter from Mr. A. Downe, a resident of Los Angeles, California, who recently visited New South Wales, and made a careful inspec- tion of the citrus groves of the County of Cumberland. Mr. Downe has an orchard of some 24 acres at Duarte, California, and can therefore speak as a fruit- grower to fruit-growers. Mr. Downe refers to the prevalence of fumigating with cyanide in preference to spraying, declaring that the latter process has been abandoned, as it causes ‘‘die back” of the fine twigs and sprouts. The freight from California to New York is 4s. 6d. per 100 lb. box a distance of 3,000 miles. Oranges are shipped east to New York and London and throughout Canada, and arrive in condition. The new crop for next year promises to be a heavy one, probably the heaviest for years, due no doubt, Mr. Downe says, to liberal fertilising and fumigating. The marketing of the enormous crop is as important as growing it, and California fruit-growers have established the California Fruit-Growers’ Exchange to perform this work. As there is nothing of this kind in existence in this Fdible Products. State, the need of such a corporation was apparent to Mr. Downe; he _ has, there- fore, been to no little trouble in collecting information on the subject. From a pamphlet issued by the California Fruit- Growers’ Exchange, forwarded by Mr. Downe, the following is taken :— “Twenty-five years ago the annual total shipments were scarcely twenty carloads. Fifteen years ago the annual shipments were approximately 4,000 car- loads, or slightly in excess of a million ee quarter boxes (a box holds 2 cubic eet). “Since that time there has been an increase from year to year, until the average of the last three seasons has reached the vast volume of 30,000 car- loads, or 11,000,000 boxes yearly. The net f.o.b. value of the crop of 1906 has been conservatively estimated at twenty million dollars. “When citrus fruit-growing in Cali- fornia emerged from the stage of experiment and past time into that of profit-seeking, the problem of marketing immediately confronted the growers. They were thousands of miles from the populous centres in which their fruit must find consumers, and they had practically no home markets nor agencies through which they could convert it into ready money at remunerative figures. It is true there were speculators in the field, but their offers to buy were at very low prices, and only spasmodic at best. This is not strange as the speculators were but go-betweens, and the markets being undeveloped they could only offer for the most part to take the fruit on consignment for grower’s account. If passing the specu- lator by, the grower sought relief by consigning his produce to the market himself, he was little, if any, the gainer. These were the conditions in the early nineties, when the citrus fruits of California orchards were less than one- tenth the present value. «““Various expedients were resorted to for the betterment of these conditions. Speculators attempted to form a compact to apportion among themselves the territory where the fruit was grown, to fix maximum prices to be paid for fruit, and also to establish f.o.b. prices, regular credits and equalise distribution in consuming markets. Growers’ and speculators together sought to regulate prices, consignments, and other im- portant questions. The most disastrous year so far as net returns were concerned that the citrus fruit industry in this State has ever experienced was 1892-3, In Riverside and all other sections, where there was any quantity of fruit to ship 138 at the time, account sales in ‘red ink” were received without number. Inmany - instances growers not only furnished their entire crops for nothing, but were also required to pay freight and packing charges, which the gross sale of their fruit did not cover. All of these efforts to improve marketing conditions were inadequate and short-lived. In the very nature of things they could not be more than partially successful, since the in- terests of growers and speculators are necessarily divergent on important points. In several localities a few growers had associated themselves to secure better packing facilities, and for mutual protection. In some instances these associations had marketed on a mutual basis. “As a result of the above-mentioned . failure of speculative shifters to sell the year’s crop at fair prices, and particular- ly stimulated by the association ex- periences, large percentage of growers sought to solve the vexed problem by an enlargement of the association idea.” “A Convention of Growers assembled at the Chamber of Commerce, Los Angeles, on the 4th April, 1903, the declared purpose of the meeting being: “To provide for marketing of all the citrus fruit at the lowest possible cost under uniform methods, and in a manner to secure to each grower a certain marketing of his fruit and the full average price to be obtained in the market for the entire season.” “Following the recommendations of this Convention of Growers, organisation of associations and district exchanges was effected in all the principal citrus fruit districts, the packing to be done by the association at cost, and the marketing through an executive committee, com- posed of one member from each district. This arrangement for the marketing of the fruit continued during two seasons, viz., those of 1893-4 and 1894-5, but not being entirely satisfactory, on October 21st, 1895, the Southern California Fruit Exchange was organised, since which date the marketing of the fruit controll- | ed by the various district exchanges and their associations has been conclusively in the hands of the Southern California Fruit Exchange, and its successor, the California Fruit Growers’ Exchange, except during the period of seventeen months, from April Ist, 1903, to August 8lst, 1904, during which time the Exchange interests combined in the sale of their fruit with the principal non- Exchange shipping interests under the name of the California Fruit Agency. The net results obtained during the Agency period were not satisfactory to [FPEBRUARY, 1909. iL 4 ¢ ; i i FEBRUARY, 1909.) the growers, and on September Ist, 1904, the Exchange resumed the sale of the fruit it controlled, independently of any other factor. “On resuming itsmarketing operations; the Exchange passed the following re- solution as a basis on which to operate :— ‘On May 20th we issued acircular, advising all growers of the dissolution of the California Fruit Agency, to take effect September Ist next. ‘Upon the formation of the California Fruit Agency, every effort was made to sell the fruit f.o.b, California. All agents were instructed to push this policy, and imen were employed as salesmen in the Sales Department of the Agency who possessed ability and much experience in that line, and who have been in the employ of the leading packers, as their salesmen for many years. ‘Immediately after the California Fruit Agency was organized, April Ist, 1903, f,o.b. orders for fruit (usual terms of inspection, ete.) were only received in limited numbers, and not sufficient to move a reasonable percentage of the crop—although climatic conditions in California were most iavourable to restrict shipments. It soon became necessary, in order to move the crop, to ship, and attempt to make sales in transit, or sell the fruit delivered at market value at the point and time of delivery. ‘Our crops are now so large that all markets should be constantly supplied with their full quota of fruit in order to consume the output. This distribution can be better accomplished by those most directly interested,—the growers themselves. The citrus-fruit-grower is no longer independent of his neighbour as to marketing his crop, but each one is dependent upon the other, especially in sofar as systematic distribution is concerned. ‘The Southern California Fruit Hx- change is composed only of growers who recogniseall legitimate dealers in the trade, and who are organised for the purpose of disposing of their pro- ducts in all markets of the country upon the most advantageous terms, and to secure distribution to the trade at the least expense compatible with the best service, securing to the consumer the fruit at reasonable prices, and to the grower the best average returns, ‘When the Southern California Fruit Exchange resumes its selling operations on September Ist next, in the absenc- of other instructions from, or a change of policy being inaugurated by the 189 Edible Productss growers themselves through their re- presentatives on its Board of Directors, the Management will endeavour to sell the fruit in such amanner as will bring the most money for the product, confin- ing itself neither to cash sales in Cali- fornia, f.o.b. sales California (subject to inspection, draft attached to bill of lading), or sales delivered, nor to any other onemethod. Its agents and repre- sentatives will be instructed to secure all orders possible from fruit, allowing the customer to take his preference as to whether he wants these orders to be for spot cash, f.o.b., usual terms, or delivered, subject of course to the confirmation of the Exchange or Asso- ciation shipping. ‘Growers or Associations of growers not connected with the Southern Califor- nia Fruit Exchange have the opportu- nity now to associate or to form new associations according to their pre- ference, ro add to conditions existing in their localities. ‘Believing that in co-operation with each other, the best net results to the growers can be obtained, we appeal to all present Hxchange members and others interested in maintaining values of orchard property to put forth every effort to secure as large a membership as possiblein our associations and ex- changes.’ “On March 27, 1905, the California Fruit Growers’ Exchange was_ incor- porated, and on September Ist following succeeded to the business of the Southern California Fruit Exchange. This change in name was deemed advisable in order that the market organisation of itself might in name, as well as in fact, become general throughout the State rather than remain local to Southern California. “The Exchange was founded upon the theory that every member was entitled to furnish his pro rata of the fruit for shipment through his association, and every association to its pro rata of the various markets of the country. This theory reduced to practice gives every grower his fair share, and the average price of all markets throughout the season. ‘Another cardinal provision of the plan was that all fruit should be mar- keted on a level basis of actual cost, with all books and accounts open for inspection at the pleasure of the mem- bers. These broad principles of full co- operation constitute the basis of the Exchange movement. “The Hxchange system } : is simple, but quite democratic, The local associ- Edible Products. ation consists of a number of growers contiguously situtated, who unite them- selves for the purpose of preparing their fruit for market on a co-operative basis. They establish their own brands, make such rules as they may agree upon for grading, packing, and pooling their fruit. Usually these associations own thoroughly equipped packing-houses. “All members are givena like pri- vilege to pick and deliver fruit to the packing-house. where it is weighed in and properly receipted for. lHvery growet’s fruit is separated into different grades, according to quality, and usually thereafter it goes into the common pool, and in due course takes its percentage of the returns according to grade. “Any given brand is the exclusive property of the Association using it, and the fruit under this brand is always packed in the same locality, and there- fore of uniform quality. This is of great advantage in marketing, asthe trade soon learns that the pack is reliable. “There are more than eighty associ- ations covering every citrus fruit district in California, and packing nearly two hundred reliable and guaranteed brands of oranges and lemons. ‘““The several associations in a locality unite to form the local Exchange, which serves aS a medium, and to a certain extent as a buffer between the associ- ations and the general Exchange. “The California Fruit-Growers’ Ex- change, referred to above as the General Exchange, consists of thirteen stock- holders, all directors, and all selected by the local Exchanges. In other words, the severa] local Exchanges designate one man each from their membership as. their representative, and he is elected a director of the California Fruit Growers’ Exchange. By this method the policy- making and governing power of the organisation remains in the hands of the local Exchanges. “From top to bottom the organisa- tion is planned, dominated, and in general detail controlled absolutely by the fruit-growers, and for the common good of all members. No corporation or individual reaps from it either dividends or private gain. ‘““Sofar we have dealt almost exclu- sively with the organisation of the Kx- change, its co-operative aspects, and general policy at home. Equally impor- tant is its organisation in the markets. ‘“‘ Seeking to free itself from the shift- ing influences of speculative trading, by taking the business out of the hands of middlemen at home, the Exchange found it quite as important to maintain the control of its own affairs in the 140 [KEBRUARY, 1909, markets, It never contemplated the opening of either retail or jobbing houses, but to put the fruit into the hands of the legitimate dealers first hand. For this purpose the Exchange established a system of exclusive agencies in all the principal cities of the country, employing. as agents active, capable young men of experience in the fruit business. Most of these agents are salaried, and have no other business of any kind to engage their attention, and none of the Exchange representatives handle any other citrus fruits. These agents sell to smaller cities contiguous to their headquarters, cr in the territory covered by their districts. “Over all these agencies are two general or travelling agents, with authority to supervise and check up the various offices, These general agents maintain in their offices at Chicago and Omaha a complete bureau of informa- tion, through which all agents receive every day detailed information as to sales of Exchange fruit in other markets the previous day. Possessing this data the sellingagent cannot be taken advant- age of as to prices. If any agent finds his market sluggish and is unable to sell at the average prices prevailing else- where, he promptly -advices the head office in Los Angeles, and sufficient fruit . is diverted from his market to relieve it and restore prices to normal level. In actual practice approximately 40 per cent. of all the fruits shipped by the Exchange is sold by public auction at point of consumption, and of the remain- ing 60 per cent. the greater part is sold at private sale at a price agreed upon between the seller and purchaser at point of arrival on market conditions as they prevail at that time. Through these agencies of its own the Exchange is able to get and transmit to its members the most trustworthy informa- tion regarding market conditions, visible supplies, &c. This system affords a maximum of good service at a minimum cost. The volume of the business is so large that ‘a most thorough equipment is maintained at a much less cost to growers than any other selling agency can offer. “During the fourteen years of co- operation in the marketing of citrus fruits under the Exchange system, the output of the State has increased from 4,100 cars in 1892-3 to 31,791 cars (including Northern California shipments) during the season of 1904-5, with a prospect of a still further increase in the volume of shipments in the very near future. ‘‘Marketing the fruit for its growers at actual cost, the Exchange has been able to bring about a great reduction in packing and selling charges, with the FEBRUARY, 1909.] | 141 result that the average cost per box of both packing and marketing oranges to Exchange growers has during recent years averaged around 35c. as against 75¢, per box at the time the Exchange was organised, when the charges by speculative shippers for packing alone was 40c. to 50c. per box, to which was added for selling 7 to 10 per cent. commission on the delivered price. ‘This co-operative movement is no longer an experiment, organised upon lines materially differing from any other co-operative organisation; all the details had to be worked out with extreme care and caution. To have failed would have been to utterly demoralise the citrus fruitindnstry, as there were no adequate marketing facilities. Serious blunders in the execution of the plan would have been almost equally disastrous. Natur- ally this Growers’ organisation has met with very strenuous and, in some in- stances, bitter opposition from the speculative elementsin the fruit trade. “The Exchange is nota Trust. It neither seeks to control production, nor arbitrarily to fix prices. It does, of course, undertake, so far as possible, by a simple method of co-operation, to displace the competition of one grower With another in the matter of packing and marketing their fruit. By purely economical, as distinguished from trust, methods, it ensures to every grower the full reward of growing good fruit, and to every association the benefit of good grading and packing.—Agricul- tural Gazette of New South Wales, Vol. XIX., Part II.

Similarly, the use of dried blood, primarily a nitro- genous manure, has increased the yield by 187 1b., while the combination of the 142 [FEBRUARY, 1909. two sets of manure (t.e., phosphate, potash and dried blood) has increased the yield by 374 lb. The mulching has shown the greatest gain, namely 402 lb. per acre per annnim. By putting the moderate valuation of 6d. per lb. on cured cacao, a figure much below market value, we may obtain an idea of the monetary aspect of the case :— Average Value per annual acre of yield per Gain in dry increase Gai | acre of cacao per acre over no- Cost of aS Plot. | cured. over a meu manure, rahe: cacao manure plot, plot, per acre. : during in pounds. at 6d. per manuring. five years, lb. of cured | in pounds. cacao.

The mere consideration of the yield of cacao does not fully explain the condition of the plots and the changes taking place thereon. When the general health and growth of the trees on the plots are taken into account, itis at once seen that the in- dividual trees on the mulched plot are much finer and are better developed than those on the other plots; the soil also is better than thatof any other plot. It is moist, friable, and full of humus, and in a_ better condition generally, which would appear to ensure good crops for some time tocome. It is also significant that this plot is well covered by trees planted at the rate of 108 per acre, while the plot receiving no manure requires 178 trees per acre, or nearly 70 per cent. more, Nextin general health and condition may be placed plot 4, which received phosphate, potash, and dried blood. This plot requires at the rate of 124 trees per acre to coverit. The number of trees on the other plots is as follows: Plot 38, 1389 trees per acre; plot 2, 155 trees per acre; and plot 1, 178 trees per acre. " As the general rule of these experi- ments, planters are recommended to manure their cacao trees. - Fepruary, 1909. Organic manures such as pen manure and liberal mulchings are doubtless the best and most remunerative. Where these cannot be obtained in sufficient quantity, it is essential to give manures containing nitrogen and phosphate, and in many cases it willbe well to supple- ment mulching with moderate applica- - tions of nitrogen and phosphate. Phosphate may be given with advantage in the form of basic phosphate in appli- eations of from 1to4 ewt. per acre. A sufficient application in most cases will be lewt-. peracre annually for several years. Nitrogen may be given in the form of sulphate of ammonia at the rate of from 1 to 2 ewt. per acre, but nitrogen should be given preferably in aform in which it is more slowly available, suchas dried blood, at the rate of 2 to 4 ewt. per acre. With the development of the cotton industry in these islands considerable quantities of cotton-seed meal may be within reach, This forms avery useful source of nitrogen, and may be used at the rate of from 3 to 6 ewt. per acre. It introduces fair quantities of phosphate and potash as well as nitrogen. The present experiments afford uo_ evidence as to the value of potash and phosphate independently of each other. - The soils of Dominica are, however, fairly well supplied with potash, and it is not likely that this constituent is urgently wanted. In the event of planters desiring to experiment with potash, it is believed that small dressings 148 Edible Products. GOVERNMENT PLOT AT PICARD. This plot was started in 1900, in order to ascertain whether cacao could be grown on thelow lands at Picard. At the time the plot was laid out, the general opinion was that this district was not suitable for cacao. Largely as the result of the success of these experi- ments considerable areas of cacao have been planted in the neighbourhood, and the success attending the newly-estab- lished fields justifies the action. This area is now regarded as one of the most promising districts in Dominica. The plot consists of one acre divided into four sections. In the early stages the whole of the plot was manured with pen manure and dried blood. Iu 1903 the area was divided into four plots, each of } acre as follows :— A. Receving pen manure. B. Receiving 2 ewbt. per acre of sulph- ate of ammonia. C. Receiving 4 cwt. per acre of basic phosphate. D. Receiving 4 cwt. per acre of dried blood, These manures are applied annually. The southern part of plot D. is found to rest on a gravelly subtratum; pro- bably the old river bed extended to this point. From 1905 this poor portion has been dressed with pen manure in an attempt to restore fertility, The firstsmall pickings were gathered of from 3 tol ewt.of sulphate of potash in 1904-5. The yield from the plots have will prove sufficient. ibeentsr.

The trees receiving sulphate of ammo- nia also present a very fine healthy appearance, but they have not yet come into such heavy bearing as the trees receiving either pen manure or basic phosphate. The plot receiving basic phosphate has given alargereturn, and the trees looking excellent condition. The foliage is perhaps not so heavy asin the plots receving pen manure or ammonia. The plot experienced no lack of nitrogen, as it has received a large number of green deessings from the careful manage- ment of the weeds which have grown upon it and have been turned in. The plot does not show indications of fall- lng off such as are referred toin con- nexion with the basic phosphate plot in the large series of experiments at Picard. It must, however, be remem- bed that this plot, with the others, Edible Products. received good dressings of pen manure and dried blood in the first two years of its existence. The dried blood plot, as explained above, is rather uneven, but there are some good trees upon it. These four plots have been carefully worked on the system which involves the careful use of weeds as green dressings. The growth of the weeds has been watched, and assoon as they reached a moderate size they are cut down and either spread as a mulch or forked in. (See ‘Manurial Value of Weeds in Cacao and Lime Orchards, West Indian Bulletin, Vol. V., p. 287). The results obtained on these plots, and the excellent condition of the soil, would appear to show that while pen manure when available is most valu- able in cacao orchards, still the condi- tion of the soil can be maintained and improved by judicious green dressing with weeds. The experiments should be continued for some years, for it will be interesting to see if the ferti- lity of plots B. and C., receiving part of manures with ammonia and phos- phate respectively, will be maintained without any other application. LARGER MANURIAL EXPERIMENTS AT PICARD. The experiments conducted in co-oper- ation with Mr. Sowray, the representa- tive of Messrs. Rowntree & Co., have given interesting results. These consist 144 [FEBRUARY, 1009, — of twelve plots. Each plot, which is + acre in extent, contains sixty-four trees and is separated from its neighbour by two rows of cacao trees. Plots 3 and 6 are separated from 7 and 10 by three rows. Measured by the number of pods pro- duced, the results show in an unmistak- able manner that manures are beneficial and remunerative in the establishment of young cacao. Judged on this basis, it is seen that pen manure has given the best results, the yield of pods of this season from this plot being two and a half times that of the plot without manure. Dried blood has resulted in large returns and so has bone meal. Each of the constituents of manures (phosphate, potash, and nitrogen, (as ammonia) has increased the number of pods ina marked degree, and this has been the case whether these constituents have been used singly or grouped in various ways. Plot8, receiving potash only, has given an abnormally high yield and must be disregarded for the moment, Plot 2 shows a considerable increase of crop as the result of the use of basic phosphate; plot 6 shows that the crop is only slightly increased by the addition of potash, while plot 4 shows that the addition of ammonia considerably in- creases the yield. For easy comparison the results may be arranged as follows :— | Yield in | Number of | Gain over |terms of dry Plot | Manure. pods per | no-manure | cacao per plot. plotsin pods.| acre in pounds.

Theaddition of ammcnia to plot 10 has greatly increased ihe yield as compared with plot 12 receiving no manure, while plot 11, receiving phosphate and potash in most probably to the phosphate. which received bone meal. addition to nitrogen, shows a still further increased yield, due Further confirmation is obtained from plot 1, Bone meal contains both phosphate and nitrogen. This FEBRUARY, 1909. } ‘plot has given a very large return, These facts go to prove that nitrogen and phos- phate are the constituents most required, while the effect of potash is doubtful. The best returns of all are obtained from the use of pen manure which contains nitrogen, phosphate, and _ po- tash, and in addition large quantities of organic matter. This latter substance greatly improves the texture of the soil and so adds very materially to its fertility. Dried blood has also given good results. This manure contains nitrogen, phosphate and potash with organic matter. The general results with compost plot 9, have not been satisfactory ; either the compost has not been sufficient, or it is unexpectedly slow in its action. (1) Very vigorous, with fin healthy foliage and robust trees, (2) Good, with healthy foli- age and robust trees. (8) Fair (4) Lacking vigorous growth, foliage poor. Judged by theappearance of the trees, we get a great deal of light thrown on the effect of manures. The best results, taking both the vigour of the trees and the yield of cacao into account, have been given by the use of pen manure. The yield is the highest of all the plots ‘and the trees are the most vigorous. Next to this we must place the bone meal and the dried blood plots. Both these manures convey to the soil nitrogen and phosphate. Following these come plot 10, ammonia; and plot 5, ammonia and potash; and then plot 4, with ammonia and phosphate; and plot 11, with ammonia, phosphate, and potash. After these, we come to a group where the trees obviously lack vigour, and where we may soon look for a decided falling off. The striking feature in this group is that none of the plots have received any nitrogenous manure. It is tu be noted that this group includes plot 2, phosphate ; plot 3, potash ; and_ plot 6, phosphate and_ potash, all of which have given good numbers of pods, and which, judged from the crop returns alone, would be regarded as satisfactory. They cannot he regarded as satis- factory, however, and a falling off in crop is anticipated. The group includes plot 9, compost; and plot 12, no-manure. 17 14 e \ Plot. 7. 5 Kdible Products, Estimating the effect of manures on young cacao trees by taking account only of the yield of cacao is likely to be fallacious for more than one reason. In the early stages there is likely to be irregularity in the manner in which young trees come into bearing, while some manures may tend to foree the trees into early bearing and lead to early exhaustion. It is therefore neces- sary to add to the statement of the yield of cacao, observations as to the general condition of the trees. When this is done in connexion with these experi- ments we alrive at very interesting re- sults. The plots may be roughly grouped according to jthe health and vigorous appearance of the trees :— Pen manure J Plot 8. Dried blood. Plot 1, Bone meal. Plot 10. Ammonia. Plot 5. Ammonia and potash. \ Plot 4. Ammonia and phosphate J Plot 11. Ammonia, phosphate, and potash. Plot 9. Compost Plot 2. Phosphate rPlot 3. Potash | Plot 6. Phosphate and potash J Plot 12. No manure. The lessons from these experiments already begin to be valuable and may be summarized thus :— Manures are useful in establishing cacao fields. Pen manure, when obtain- able, is likely to give the best results. Efforts should be made to increase the humus in the soil as much as possible, Manures_ supplying organic matter are desirable as they tend to maintain the supply of humus. Nitro- genous manures are essential ; without nitrogen the trees lack vigour. Phos- phatic manures increase the crops, but should not be used without nitrogen. It would probably be good policy to use nitrogenous and phosphatic manures together. The effect of potash is not very clear. It is probably notat present urgently required as a manure. It is recognized that some of the plots are not likely to improve under the manurial treatment they are receiving, but their retrograde movement, should it occur, will throw valuable light on important points bearing on the manur- ing of cacao. This will entail some loss upon owners, butit is hoped this pros- pective loss may be faced for the sake of the valuable information likely to be obtained. Edible Products.

THe AVOCADO. First, we will consider the avocado, which has always been considered a difficult fruit to ship. Ido not consider it such. I consider that the avocado is a comparatively easy fruit to ship if it is handled in the proper way. The picking of the fruit should be done within as short a time as possible previous to the sailing of the steamer. The avocado begins to soften very rapidly after itis picked, and as soon as that softening process begins, your troubles begin. Youcannot then arrest successfully the maturing process and preserve the fruit. You should get it into cold storage as rapidly as possible after picking, and I would say that under our present facilities it is not quite safe to pick the fruit and place it in cold storage and then take it out to putit in the steamer, because the refrigerating compartment of the steamer, where you put your fruit in, has to be kept opea for the reception of other fruit, and your fruit which has become chilled then becomes warmed again and then chilled, and these rapid changes in temperature are greatly con- ducive to the deterioration of the fruit. The fruit should be cut with great care so as to avoid bruising. Perhaps it seems superfluous to say this, yet I have seen people who are in the fruit business handling avocados in a way in which a good down-east farmer would not treat his potatoes; I have seen them packed in boxesand specimens dropped from this height (indicating about 34 to 4 feet) on to a concrete pavement floor and then picked up and put in the boxes as first-class merchantable avo- eados. That won’t do. They must be handled with extreme care to avoid all bruising. The stems should be cut, as IT have told you should be done in the ease of oranges and lemons. Cut the stem comparatively near to the fruit and don’t put in leaves—do not cut the stems long soas to include the leaves; about a quarter of aninch oran eighth of an inch is sufficient, that is, beyond the natural joint. The packing should be done also with care. [ have brought here a fewcrates to illustrate the dif- ferent possible packages, This crate (in- dicating) holds approximately twenty- four avocados. There isa smaller crate which we have used which holds a dozen. It is exactly the same as half of this. This crate is more useful in sending smaller shipments that are going for private orders, In this crate you will see that the fruits are only one tier 147 Edible Products. deep. All fruit should be wrapped with rather thin and yet strong paper. They should be placed so as to pack snugly. Tf you will recall the shape of the average avocado you will notice that it can be adjusted to a box of this size, even though it be a little smaller in dia- meter or alittle larger. The adjustment can be done by means of tilting. If the avocado is long you can place it like that (indicating) if it is wide, it can be tilted a little lowerand the next one be put this way (indicating); if this is point up, the next one can be point down, and you can tilt it just as muchas is neces- sary, the only requisite of the box being that it must be high enough to receive the avocado if it is lying directly on its side. These boxes we fourd were not quite large enough to receive the largest avocados. I would say, do not put any paper between the fruits. I found in San Francisco that many of our shippers from here were sending the fruits up there in orange crates and larger boxes than that and packing paper, wads of paper, in between the fruts. Doubtless the idea was to keep the fruit from bruis- ing, but what is the result? You have a solid mass of fruit and paper packed closely together; the circulation of air is rendered impossible, and it is about like trying to refrigerate a wad of cotton—you can’t get the refrigeration into it; rather you can’t get the heat out of it, you do not get the circulation of the air, the cold air, about the fruit. And there is no need of this paper if the fruit is carefully placed so as to be snug. Do not put in any leaves, The shipping must be in refrigeration only. When we first commenced shipping, people told us that we could not ship in refrigeration without the fruit all turn- ing black. That depends upon the refrigeration. But ventilation is out of the question, ventilation without refri- geration is out of the question—the fruit will all arrive in the market in a condition too soft to be received by the wholesale trade. A great deal of it may arrive there in suitable con- dition for eating, but the trade will not take it in thatform. The avocado will endure retrigeration for a term of three weeks any way. The exact time we have not determined, but we have determined that it will not endure refrigeration as long as most temperate zone fruits. The first deteriorating effect of refrigeration is observable in the darkening of the flesh close to the seed, and then the flesh begins to turn rancid; but it is perfectly safe to send them as faras San Francisco or as far as New York, so far as the time ele- ment is concerned, The temperatures Edible Products. that are best adapted for the refri- geration of avocados has not been deter- mined. We have carried them as low as between 40 and 45 and as high as 50. Fifty degrees I am satisfied is too high. Our next hope is to try them between 45 and 50, and I think that somewhere in there we will find the optimum tem- perature. The temperature must be con- stant, for variations intemperture, as I have said, are deleterious to all fruits. HANDLING THE FRUIT IN THE MARKET. It is necessary when the fruit arrives in the market, if there is not asale for it immediately, that it should be stored in refrigeration. If it is exposed, even in San Francisco where it is cool, the ripening process begins, and, as I have said before, once they get well under way it is difficult to arrest them and preserve the fruit. Itis necessary, therefore. for the fruit to go into cold storage if there is not immediate sale for it. As tothe market demands for avocadys in San Francisco: As _ to colour they prefer a green avocado. I don’t know why, and I don’t think they do, but they have been getting green avocados from Tahiti, and _ pos- sibly that may be the reason; but thatis their preference at present. In other parts of the United States, well, from Pitsburg west they have no perference. because they scarcely know the avocado —it is an unknown article—butin San Francisco it isa known fruit and that is what they are calling for—green fruit —although they will take the red or the brown. I think that that is a matter, however, in which a change could easily be brought about, provid- ed our best avocados should turn out to be the brown or the red. Some of our best varieties may be these. The market demands that the fruit be firm asI have already told you, You cannot put fruit beginning to soften on the market. In the first place, it is a high-priced fruit, and the buyers who handle the fruit, will not take the risk of buying fruit, at a high price which, if it is not sold within a day or two is going to be a dead loss; but if the fruit is firm, it will sell and sell at a good price. We should be careful, in avocados, to send only those quality. That is important. makicg our reputation, and we make a good one. The prices which this. fruit receives in San Francisco range from a dollar and ahalf to two dollars and a half per dozen, Fruits that are of good quality and firm will sell for $2:50 per dozen. As to the sell- selling agent, [ think I will postpone sending of good We are want to 8 [FEBRUARY, 1909. a discussion of that question until we come to a later part of the evening when we are talking of the marketing of other fruits since the problem is the same, Tot MANGO. The marketing of: the mango is about the same as that of the avocado with the following exceptions:—The crates while they must be small, need not be so smallas in the case of the avocado. Two or three layers will be endured a great deal better in the case of the mango than in the case of the avocado, but you must be careful not to pack them in large packages. The refri- geration can be more prolonged in the case of the mango thanin the ease of the avocados. The mango can_be kept for at least six weeks safely. The mar- ket demands for mangoes are nil. There are no:demands. In San _ Francisco where the fruit comes in spasmodically from Tahiti and from Mexico, the sale is a fairly ready one, rather slow, but the supply is not constant; and, the sup- ply being inconstant. there is no con- stant demand, for that isa principle in fruit marketing ; a constant demand pre- supposes a constant supply. The mango weevil is perhaps, our greatest enemy at the present time, our greatest obsta- cle in the way of a mango _ shipping industry. We have the mangoes, we have the varieties, and we know we can grow them. We know also that such fruit can be sold, though there is no market now or a very limited one, but a market for such fruit as the mango can be created. But the mango weevil is present here as you know. The larvee hatches in the egg in the seed, and because it is in the seed you cannot examine the exterior of the fruit and know whether you have the mango weevil or not, and hence the inspectors on the mainland feel that it is a very important thing that they should see that the mango weevil does not get into California and thence into the whole United States. It is not yet determined whether the mango weevil will affect other fruits than mango ornot. I be- lieve the entomologists tell us that it has not been reported upon any other fruit or plant than the mango. Yet eareful men wish to avoid all chances, and we will have to expect that our fruits will be carefully examined when they reach San Francisco, and if they are infested with the weevil they will be turned down. THE PAPAIA. The picking of the papaia for the San Francisco or for any shipping market should be done when the faintest things of yellow appear. As in the case of the Feprvuary, 1909.1 avocado, it should be picked as_ nearly as possible to the time of the sailing of the ship. In picking the papaia the stem should be cut about an inch or an inch and a half long. Here there is opportunity for some latitude, as the length of the stem may be varied slightly to facilitate the packing of the fruit. This crate (indicating) is adapted to the packing of the smaller papaias of the long type. If the papaia does not just fit here in its length, you can make some slight differences in the cutting, cut the stem half an inch longer or half an ineh shorter and this crate accommo- dates them. The papaia should be hand- led with carealso. The wrapping should be done with rather heavy paper and it is preferable to have it glazed, because if any fruit begins to decay or to get soft, an unglazed paper will allow the moisture to pass through to the adjoin- ing fruit more quickly than the glazed paper will. The shipping must of neces- sity be in refrigeration. Ventilation alone is again out of the question in the case of the papaia, and extreme care is necessary on the part of the steam- ship agents and everybody who handles the fruit to see that it is not bruised. Picking upacrate of fruit and letting it drop an inch or an inch and a half jars the fruit and bruisesit, The papaia is unknown in the markets, butit isa taste which is rapidly acquired, as you know, by almost everybody. lEvery- body who comes to the islands either enjoys the fruit at first contact or very rapidly acquires the taste; and I believe that a good market for papaias could be worked up, particularly during the season when the cantaloupes cannot be found in the market. THE BANANA. The banana should be cut before it becomes too ‘‘full,” as the term is used. You will recall that a banana when itis immature has ridges—corners—on it. When it becomes fully mature and.the fruit begins to turn yellow, those ridges on the Chinese variety and also on the Blue-fields or Jamaica variety appear. When the fruit has become fully rounded it is too far advanced for shipping. Nobody can describe the stage of maturity at which itis best to cut the fruit—that has to be determined by experience. The fruit must be cut while it still retains the ridges, but the degree of maturity will depend upon the distance to market. The wrapper.— Grass has been used as a wrapper. Banana leaves are more commonly used and are very much preferable. The banana leaves may be kept drier than the grass, Grass has a tendency to absorb moisture and to hold moisture 149 dis- * Hdible Products. and dampness, and that causes the fruit to sweat and causes the ‘Ripe Rot” to develop, the fruit to turn black and to soften. Mistakes were made, particu- larly in the Hilo banana trade, in ship- ping the fruits in moist grass, On the mainland last summer I found a banana drum being used for the shipping of bananas from the great central markets into the tributory territory. These drums were constructed of heavy card- board, and were just large enough to contain a single bunch. They are made of two sizes, large enough to contain a single bunch. Around the top of the drum the top hoop held a strong piece of paper in place, which was drawn up from the top of the drum and tied to the stem of the banana, and that was the way in which the fruit was carried—by its stem, Whether that would be practicable for our shipping Ido not know. I have sent for some of these, and we hope to have them on hand and give them a closer examination, and possibly we may be able to give them a trial. They are also making a similar drum ont of veneer instead of the paper. Refrigeration is absolutely not adapted for the banana. Bananas shipped in refrigeration turn black and never ripen. The‘ banana trust,” as it is called—the United Fruits Company— ship their bananas across the hot plains in the summertime with ice—in the ice bunkers of the refrigerating cars—but they are always watched; frequently the doors are opeu, the ventilators are opened. These trains are always accom- panied by an attendent, who sees to it that the temperature never gets down below. The ice is simply to overcome the intense heat and hold back the ripening a little. The Bluefields versus the Chinese variely for shipping.—The Chinese banana, as you know, is very subject to what is known as the “Ripe Rot” disease. That is the fungus disease that causes the banana to become spotted, speckled with little black specks. When the disease spreads and the black specks become united, it forms large blotches, which in the last stages of the disease— I mean the fruiting stages of the fungus —produce a reddish, roseate tinged spot where the black spot was previously. That you may not have noticed, but if you will get some bananas and allow them to ripen and rot, if they have these black spots I think you notice finally this red fruiting stage of the fungus. The Bluefields banana is quite resistant to the disease and, as a consequence, it arlives in the market in a bright yellow form. Sometimes you see black spots on them where they have rubbed to- Edible Products. gether or where they have rubbed against the next bunch, because they are shipped naked, without any wrap- ping, but this is due to bruising. The Bluefields or Jamaica variety holds to the bunch better than the Chinese. There has been a complaint against some of those that we have grown here. Though that complaint may be due in part to our soil and climate, I believe that it has been due to hanging the bunches the wrong way. The Chinese banana is hung in one direction and the Bluefileds in another, as I will show you in the slides later. A Bluefields banana hangs close up to the stem of the bunch, and as it grows from the tree, the in- dividual fruits come out like that (indicating)and goup. Now if you hang the bunch up that way in the market, when the fruits begin to ripen, the weight simply breaks them off; if you reverse the thing—hang them up by the smaller end—they hang more naturally and their weight is a pull rather than a thrust and they will stand it. The capacity of the pacific coast for bananas, as nea as Iam able to estimate it from the information which I have gathered in many cities on the western slope, is about 826,000 bunches per annum, and of these Hawaii ships about 15,000 bunches a month. You will see that our competitors ship a great many more bananas all the way from New Orleans or Mobile than we ship from here, and pay high freight rates on them, too. There isa freight rate of about $1:25a hundred, if I recallit, from New Orleans to any pointon the Pacific coast. The cooking bananas have not got into the market at all. I believe there is an opening for cooking bananas in the markets. Some of our ‘‘maia maoli,” the variety that is most commonly used for cooking, the common cooking banana of our markets, I believe would find a ready sale in the mainland markets if the people ever became acquainted with them. There certainly is no fruit more delicious when properly cooked thana ‘*maia maolli.” THE PINEAPPLE. There are a great many points to be considered in the proper shipping of pineapples. Here, again, I want to emhpasize the matter of the care of handling. The packing of a ton or a ton and a half of pineapples on a wagon loose, rubbing against each other, over rough roads and perhaps without springs on the wagon, certainly is not the advantage of the fruit. In all experi- ments we have found that pineapples cut with long stems carry to the market in very much better condition than 150 [FeBRUARY, 1909, those that are cut with short stems. Now, as to packing: At the present time the large portion of our pine- apples that go to the market as fresh fruit are packed in a erate that is in my opinion entirely too large for the fruit. We have the most delicate, the most delicious and the largest fruit, the best pineapples that are commonly found in the markets. We put them into the largest crate—the largest package—of any pineapples that go into the market. We are at the ex- tremes in both ways: the best fruit, the poorest package. Several attempts have been made to use other erates, and some of them are an improvement. There is a crate devised by Mr. Byron O. Clark (who is present with us,to-night) which is an improvement in that it contains much less fruit and has rounded corners so that it does not receive as many opportunities to have the staves split off. It comes as near the advantages of the round or barrel form of any crate that we have tried. As to packing material, there appears to be very little differ- ence whether we use excelsior or dried wild grass, provided the latter is per- fectly dry. ‘The danger with grass is in using it when it is not perfectly dry. The paper wrapping should be heavy, and as in the case of the papaia, it is better that it should be glazed. Hach wrapper should be large enough to cover the whole fruit, including the base, but not necessarily the crown; it can be pressed about the crown and made tocover the stem. It is import- antthat there should be a solid pack, There is nothing here (on the black- board) in regarding to shipping, but I believe that that is our most import- ant problem at the present time, that is, to get suitable shipping facilities. What we need is steamers that will carry the fruit with gcod ventilation, keep the fruit cool and keep the circu- lation of air about it. Another need of equal importance is an organization which can place in the important main- land market representatives to handle our fruits, an organization to act as the representative of the Hawaiian growers. What [ am saying nowin regard to pineapples applies to every fruit that I have discussed, but it is most practicable at the present time in the case of pineapples, because that in- dustry has grown to assume such large proportions, Icannot stop to tell you all the reasons for this. I have brought here a number of bulletins at Mr. Pope’s suggestion, bulletins covering the sub- ject of citrus fruits, which I have discussed with you, and also the mango, FREBRUARY, 1909, | and this bulletin on the marketing of Hawaiian fruits. In the latter part of this you will find’something of my ideas in regard to the marketing systems and the absurdity that appears to me to be involved in the so-called ‘‘Commission System ”’—‘‘ consingnig system,” and a better system whichI think ought to be inaugurated. I think we will take the few minutes that remain to run through a few of the sildes which will illustrate some of the things which I have said. A number of slides of the different fruits were then exhibited, with explan- ations by Mr. Higgins. In answer to a question as to the advantage of sealing the ends of various fruits with sealing wax or other sub- stances to prevent diseases, etc., the speaker said that it had not as yet been determined definitely whether such sealing was an advantage or not ; that experiments would have to be conducted with the different fruits and sealing materials to decide that point. The advantage would bein preventing infection, but in many cases the spores would have gained entrance before the sealing process had begun.—Hawiian Forester and Agricuturist, Vol, V., No. 5, May, 1908. SWEET POTATOES. (Concluded from page 46.) HARVESTING SWEET POTATORS. TIME FOR DIGGING SWEET POTATOES. The harvesting and marketing of sweet potatoes direct from the field begins about the middle of August and continues until the crop is all disposed of or placed in storage for winter marketing. During the early part of the harvesting season the yield is light, but us arule the prices paid are good. The supply for home use and _ those potatoes that are to be kept in storage should not be dug until just before frost. In the localities where frosts do not occur until quite late in the season the sweet potatoes ripen and the vines show a slight tinge of yellow when ready for handling. EFFECT OF FROST ON SWEET POTATOES, The foliage of the sweet potato is very tender and is easily injured by frost. A light frosting of the leaves will do no harm, but should the vines become frozen before digging they should be cut away to prevent the frozen sap pass- ing down to the roots and injuring them. Where there is a heavy yield of potatoes the soil is frequently cracked or the ends of the potatoes protrude above ground and are liable to injury from severe frost. 151 Hdible Products. If on account of rainy weather or for any other cause the potatoes cannot be dug before frost or immediately after- wards, the vines should be cut away and the potatoes removed at the first opportunity. If cold weather continues it may be necessary to draw a little extra soil over the hills to protect the potatoes, or the vines may be piled in a ridge over the row. A very slight frost- ing of the potatoes will cause them to decay within a short time after being placed in storage. METHODS OF HARVESTING SWEET POTATOES. For digging a small area of sweet potatoes, the spading or potato fork jis suitable. When digging by hand, the work will be greatly facilitated by first throwing a small furrow from one side ot the row by means of a one-horse turn- ing plough. The removal of sweet pota- toes from the soil in large quantities is generally accomplished by the aid of sweet potato diggers or ploughs. These implements are provided with two sharp rolling coulters that cut the vines ahead of the plough, and differ from the ordinary plough in having a moldboard that does not turn a furrow and termi- nates ina number of rods or an exten- sion of the moldboard for separating the potatoes from the soil. Where no special digging device is available, the ordinary two-horse turn- ing plough is frequently used, a rolling coulter being attached to the beam to cut the vines. After ploughing out the sweet potatoes it will be necessary to stir the soil in order to fird those that become covered, The machines em- ployed for handling Irish potatoes may be used for digging sweet potatoes, but are not entirely satisfactory for this purpose, as they bruise and otherwise injure sweet potatoes. It is desirable that the soil should be comparatively dry at the time of harvest- ing sweet potatoes, and bright, drying weather is essential to the proper hand- ling of the crop. Sweet potatoes differ from Irish potatoes inthat they are not so easily injured by sunlight. However they should not be exposed for any length of time if the sunshine is very warm. During the handlingin the field it should be the purpose to remove all soil and surface moisture from the pota- toes. Sweet potatoes should not lie exposed upon the surface of the ground during the night. MARKETING DIRECT FROM THE FIELD. Where sweet potatoes are grown in large quantities for early marketing it is the practice to dig, pack, and load, Rdible Products. all on the same day, direct from the field. As the potatoes are gathered up behind the diggers they are sorted into the various grades and packed into ventilated barrels ready for — ship- ment, When the barrels are packed in the field they are as a_ rule covered with burlap or similar material. In parts of New Jersey the potatoes are sorted in the field and gathered into five- eighths-bushel baskets, in which they are hauled to the depot platform, where they are packed into bariels and headed. More than one-half of the commercial crop is marketed direct from the_field without the use of packing sheds or storage of any kind other than that provided by the transportation com- panies. GRADING AND PACKING, In sorting sweet potatoes preparatory to packing, about four grades are recog- nized as fancy, primes, seconds, and eulls. Those packed as fancy include only the most select, both in size and shape. The primes include all those adapted to general first-class trade, while the seconds include the smaller and more irregular stock which goes to a lower priced trade. The culls are not marketed unless good stock is exceed- ingly scarce, andasa rule are used for feeding to hogs. Sweet potatoes are usually shipped in barrels holding eleven pecks each. Some markets require that the barrels be faced and headed, while for others the tops are slightly rounded and covered with burlap. Small lots of extra-fancy sweet potatoes are sometimes shipped in one bushel-crates having raised tops : also in patent folding crates. Throughout the process of handling care must be exercised to see that the sweet potatoes do not become bruised, for upon this their shipping and keeping qualities greatly depend. STORAGE OF SWEET POTATOES. Methods of Storing. Unlike most perishable products, the sweet potatoe requires warmth and a dry atmosphere while in storage. The method of storing will depend both upon the locality and the quantity of potatoes to be cared for. The temperature and conditions of a rather living room are admirably adapted for keeping sweet potatoes intended for home use in the North, while in the South they may be placed in pits or stored in outdoor cellars. The home supply may be placed in crates and stored inaloft over the kitchen part of the dwelling. Sweet potatoes should not be stored in bags or in barrels without ventilation. 152 {PEBRUARY, 1909. PITS AND CELLARS. Where large quantities of sweet potatoes are stored for winter market- ing, the method employed in the Southern States is to place them in out- door pits and cellars, while at the North some form of heated storage house will be required. Whether the storage be in pit, cellar or house, a dry, warm atmo- sphere with ventilation is essential to good keeping. Storage pits should be located where. the drainage is good. First, a little of the surface soil is thrown back to form a level bed 8 or 10 feet in diameter, then two small trenches crossing each other at right angles in the centre of the bed are excavated and some boards laid over these. At the point where the trenches cross, a loosely nailed 4 by 4 inch box is set on end to form a flue up through the potatoes. The earth floor of the pit should be covered with2 or 3 inches of hay, leaves, or pine straw, and the potatoes piled ina large, conical heap around the ventilator flue. When the heap is of the desired size, the potatoes are covered with hay or pine straw, and soil to the thickness of 5 or 6 inches is added, but the trenches and flue are kept open until it is necessary to close them to keep out the frost. In the South sweet potatoes are frequently — kept throughout the winter by this method. OUTDOOR CELLARS. This form of cellar, built entirely above ground, consists of a line of posts through the centre supporting a ridge pole upon which is placed one end of planks or puncheons with their opposite end resting on the ground on either side of the ridge. The ends of the inclosure are boarded u2, adoor being provided in one, and the structure covered with sod to a thickness of 5 or 6 inches. The sweet potatoes are stored upon the earth floor aud the door is kept open for a time for ventilation. If the house exceeds a length of 12 or 14 feet, a top ventilator should be provided. VARIGTIES OF SWEET POTATORS. Of the large number of varieties of the sweet potatoe there are not more than ten that are now of great commercial importance in the United States. For the market that requireadry, mealy- fleshed potato those varieties belonging to the Jersey group are suitable. For the southern trade and where a moist- fleshed potato is desired these commonly designated as yams are in damand. Among the Jerseys that are extensively grown are the’ Big-Stem Jersey, the Yellow Jersey, and the Red Jersey. FEBRUARY, 1909.] The principal varieties of the yam group are the Southern Queen, the Pumpkin Yam, the Georgia, the Florida, and the Red Bermuda. Of the varieties men- tioned there are a large number of special strains, known under many local names. In the selection of varieties for home use one must be governed largely by locality. Asarule those of the Jersey group will thrive farther north than those of the so-called yam types. For market purposes the particular variety or strain grown in the vicinity should be first selected, and afterward other varieties may be experimented with ina small way. The following brief descriptions of a few of the leading varieties may be of assistance in selecting those best adap- ted to various conditions of soil and cli- mate :— Big-Stem Jersey.—This variety is the most popular among the growers who are supplying the northern and eastern markets. It is a form of the Yellow Jersey, having been selected for its pro- ductiveness and dry, yellow flesh. The vines are slender and long; the potatoes are of spindle shape and inclined to grow rather large; colour of potatoes yellow ; colour of flesh light yellow or deep cream. While this variety yields heavily. it is unfortunately a rather poor keeper, and its flesh is inclined to become dry and “punky” toward spring, It will thrive well toward the north, but is better adapted for use as acommercial variety than for home consumption. Yellow Jsrsey.—The vines of the Yellow Jersey variety are long and more slender than those of the Big-Steam Jersey, and the potatoes are of spindle shape, but much smaller; otherwise the two varieties are very similar in appearance. The flesh is dry and mealy. This variety is a fairly good keeper and retains its quality well. Itis adapted for home use and thrives under a wide range of conditions, but does not yield heavily enough for commercial purposes, Red Jersey.—This is similar to the Yellow Jersey variety, except that the roots are red anditis more productive under most conditions. It is suitable for home use. Southern Queen, or Hayman.—The vines of this variety are strong and vigor- ous; the potatoes are large, thick, and blunt at ends or of short spindle shape; the colour is white or light cream, while the flesh is of cream colour, becoming darkened in cooking, moist, and very sweet. This variety ismost extensively grown for market purposes where a 18 153 Edible Products, sweet, moist-fleshed potato is demanded. The Southern Queen yields well, is an ex- cellent keeper, and is adapted for both marketing and stock feeding and for home use in the South Atlantic and Gulf Coasts States, but it does not mature when grown in the extreme North. Pumpkin Yam.—The vines are vigor- ous, short, sometimes of a bunch habit. The potatoes are of short spindle shape or quite round, witha dull yellow colour on the outside. The flesh is orange or sometimes yellow and marbled with orange; it is moist and has a flavour very similar to that of good squash, This variety yields well and is adapted to home use and to stock feeding throughout the South. Georgia, or Split-Leaf, Yan.—The vines of this variety are slender and long; the potatoes of medium size, spindle shape, yellow, the flesh a light yellow, marbled with salmon. The quality of this variety is excellent and very sweet, but it isa light yielder. It isa splendid sort for home use throughout the South Atlantic and Gulf Coast States. Red Bermuda.—The Red Bermuda vines are large and vigorous. The potatoes are usually large and overgrown with heavy ridges and veins. Thecolour of the potatoes is rose red; flesh, creamy ; quality fair but not so sweet as Southern Queen. This variety is a heavy cropper and suitable for feeding to stock. Itis one of the fewso-called yams which thrive in the northern portion of the sweet. potato area. Florida.—The vines of the Florida variety are large and vigorous. The potatoes are rather large, light salmon yellow, smooth and regular, of short spindle shape, with light yellow flesh. This variety is not so sweet as the Georgia and is inclined to be dry and mealy. It yields fairly well and is adapted for home use, Pierson.—The vines of the Pierson are similar to those of the Red Bermuda variety. The potatoes are light yellow, of short, spindle shape, very rough, with cream-colored flesh. This sort is exten- sively grown for the earliest market, but itis of only fair quality. It yields wellif allowed to remain until late in the season. Black Spanish, or ‘** Niger Choker.”— The Black Spanish vines are very long, vigorous, and dark purple incolour. The potatoes are long, cylindrical, crooked, or bent; dark purple in colour, with snowy white flush and poor quality. This variety is grown mostly for stock feeding. Edible Products. 154. Shanghai.—The vines of the Shanghai variety are large and _ vigorous; the potatoes long, cylindrical; the outside colour almost white, The flesh is creamy white, becoming darker in cook- ing. When baked the flesh is somewhat dry and mealy and the flavour rather poor. This variety yields fairly well and is adapted for use as stock food in Gulf Coast States. Cost OF PRODUCTION AND RETURNS. The cost of growing an acre of sweet potatoes will vary with the cropping plan and the extent to which the crop is grown. On an average the cost of growing an acre of sweet potatoes in the regular commercial district is about as tollows :—Rental of land, $8;, ploughing and fitting, $5; fertilizers, $20 ; 10,000 plants, $10; planting, $5; cultivating, $9 ; digging and marketing, $25; total, $78. An average yield of sweet potatoes is at the rate of one barrel to 100 hills or 100 barrels to an acre. The price per barrel paid the grower is seldom less than $1°25, and $2°50 or $3 is notuncommon. During good seasons the net. profit from one acre of sweet potatoes is about $75. While occasionally the net returns are from $100 to $150 an acre for a single season, there are seasons of crop failure or overproduction when very little, if any, profit is realized. The sweet-potato growers on the eastern shore of Virginia asa rule plant about 10 acres insweet potatoes, and this constitutes their money crop. The remainder of the cleared portion of their small farms is devoted to corn, pasture, and hay, all for home use. Here the sweet potato crop is grown almost entirely without the aid of hired help, and the cost of production does not exceed $40 an acre. Where the crop is stored the gross returns are greater, but the cost of production is increased pro- portionately. UsEs OF SWEEr POTATOES. The uses of the sweet potato as a table vegetable are too important and too well-known to require more than brief mention in a publication of this character. In preparing them for the table they are baked, boiled, fried, or braised, while for pies they are used inthe same manner as pumpkins. A number of attempts have been made to build up an industry for the production and sale of desiccated sweet potatoes and sweet potato flour. There is doubtless a great field for this class of goods, especially for export and for ship supplies. Usis For Stock Foon. The vines of the sweet potato when properly cured make a medium grade ’ produced, of hay for feeding to cattle and sheep. In the green state the vines are eaten by sheep, cattle and hogs, but their feed- ing value is comparatively small. The potatoes are fairly well adapted to feed- ing to range cattle, sheep, and hogs. although their nutritive value is quite low, and they require the addition of cotton-seed meal or grain to make a balanced ration. On farms where sweet potatoes are grown extensively the culls are fed to hogs, together with a oue-third or one-half ration of corn. By employing one of the heavy- yielding varieties of sweet potatoes, such as the Southern Queen or the Ber- muda Red, and drying and pulverizing them, a splendid stock food may be duc especially when _ sufficient grain is added to form a balanced ration. The principal uses of sweet potatoes are, however, for the table, and the de- mand for this purpose is rapidly in- creasing. From the fact that by the aid of commercial fertilizer alone sweet pota- toes can be grown on comparatively poor landand largely by the use of labour-saving machinery, this crop may in a great measure solve the problem of how to occupy the ‘‘ worn-out” cot- ton and tobacco lands of the South, especially if employed in a rotation including corn, peanuts and grass. By the perfection of some means by which sweet potatoes could bedried and con- verted into a condensed stock food on the farm, they in conjunction with corn, peanuts, and a littie hay would serve to keep the stock on southern farms in good condition during the winter. When removed fromthe ground the sweet potato contains about 71 per cent, of water, 1°5 per cent. of protein, 25 per cent. of nitrogen-free extract, and 0°35 per cent. of fat. It will be noted that both the protein and fat content of the sweet potato are compara- tively low. The analysis of peanuts shows that the protein and fat are both quite high, and by combining them with sweet potatoes at the rate of one bushel of peanuts, ground in the shells, to three bushels of sweet potatoes are nearly equal to one bushel of corn in feeding value, but in order to make them satisfactory as a stock food it is necessary to add peanuts, cotton- seed meal, or grain. USE FOR PRODUCTION OF ALCOHOL. The starch and sugar content of sweet potatoes varies considerably in differ- ent varieties, but as a rule they con- tain about 16 per cent. of starch and 4 per cent, of sugar, making a total of 20 FEBRUARY, 1909. er cent. of aleohol-producing material. tis possible that sweet potatoes will become one of thechief sources of de- natured alcoholin the United States, but at present the methods of manu- facture have not been sufficiently per- fected to warrant their use for this pur- pose ona farm or community basis.— O. S. Department of Agriculture. Farm- ers’ Bulletin, 324, Sweet Potatoes. A. B.C. OF LIME CULTIVATION. (Concluded from page 42,) HAND-PRESSED LIM® OIL. _ Lime oil is used in perfumery and for soap making. The hand-pressed _pro- duct is obtained by pressing the limes by hand over an ecuelle pan. The ecu- elle is ashaliow, concave, circular cop- per pan studded with blunt spikes on its concavity and with a receptacle at the base to catch the oil. The work of obtaining hand-pressed oil is done by women, who usually select the best limes and pass them quickly with a circular movement over the blunt spikes, ex- erting sufficient pressure to break the oil cells in the skin of the limes. The oilruns into the receptacle and is col- lected from time to time in bottles, It is then settled, and afterwards is passed through filter paper into copper vessels. These vessels are usually exported in boxes. A barrel of limes will give from 3 to 44 oz. of oil by this process, and the usual price paid for extracting the oil is ld. per oz Atthis rate, women who have become expert by practice at this work are able during the height of the crop season to earn good pay. The yield of oil varies according to conditions of moisture. In _ localities where the annual rainfall is from 60 to 100 inches, the citric acid content of the juice of the fruitis high, and the yield of oil from the rind of the fruit low. Where the rainfall is high—say, from 130 to 200 inches—the citric acid content is low and the yield of oil high. DISTILLED LIME OIL. When lime juice is to be concentrated it is first distilled in order to obtain the oil. In thecase of estates which ship raw juice, the scum that collects on the juice in the settling vats is alone distilled. The oil is exported in either copper or tin vessels which are packed in boxes. It costs less to produce than _ hand- pressed oil, but commands a lower price. Stills fitted with steam coils are the best, but itis only in a very few cases that steam is available on estates. 55 KHdible Products. The yield of oil by distillation is from 3 to 50z. per barvel of limes, or taking 80 barrels of fruit to make one hogshead of concentrated juice, from"15 to 25 Ib, per hogshead, according to locality and conditions of moisture. A gallon of distilled oil weighs 9 lbs. Appendix I. CITRATE oF LIME. The following information on citrate of lime has been obtained by the Impe- rial Department of Agriculture from manufacturing chemists in London and New York :— Messrs, Sydney Harvey & Co., 48, Mark Lane, London, E.C., write as follows :— ‘Citrate of Lime is preferred to con- centrated juice by our acid makers, because the tormer is more easily worked, and is altogether a more satisfactory article to deal with, and to the producer himself, citrate of lime is also a better article. In the first place, a higher price is paid for citrate of lime than for juice, and there is a considerable saving in freight, casks, and loss by leakage. ‘Up till a few years ago, the whole of the Sicillian production was in con- eentrated juice, but when the makers once realised how much more satis- tactory citrate of lime was, the making of concentrated juice ceased entirely, and now we receive from Sicily some- thing like 5,000 tons of citrate of lime. ‘There is no chance whatever of the demand for citrate of lime falling and returning to concentrated juice, We believe that more citric acid can be saved in making citrate than in concen- trating juice.’ The Powers-Weightman-Rosengarten LORRY Philadelphia, write as fol- OWS :— ‘The cost of a citrate plant cannot be very great, and we believe the money spent in installing the same would be quickly returned through the increased economy and efficiency. ‘Citric acid contained in citrate of lime sells at a higher price than that con- tained in concentrated juice. We would give preference to citrate as against concentrated juice, and the tendency is strongly setin that direction and will remain so. ‘We have never determined — the saving in making citrate, but have always considered it to be at least 10 per cent.’ Edible Products. 156 The following circular on citrate cf lime isissued by the above Company :— ‘In some places citrous juices are simply concentrated in copper kettles over an open fire. This concentrated juice is placed in suitable containers and shipped to us. We cannot recommend concentration, as some of the acid is destroyed, and the evaporated juice is not as valuable per unit of citric acid contained, as the product we now des- cribe, viz., calcium citrate. ‘Calcium citrate is a combination of calcium and citric acid. Its most useful property is the fact that it is in- sOluble in hot water; hence, when the proper calcium salt (chalk, whitening or slaked lime) is added toa boiling liquor containing citric acid, the liquor is robbed of its acid, and the latter is recovered in the form of calcium citrate. ‘It is necessary to have a steam boiler useful for generating steam rather than for power; the steam from this boiler is used :— 1. To heat the juice in a still in order to drive off the oil. 2. To keep the juice boiling hot whilst it is converted into calcium citrate. 8. To heat water with which the calcium citrate is washed. 4. To heat the driers product is dried. ‘We now describe the method for producing calcium citrate from limes, waste lemons, etc. This method might be subject to changes according to con- ditions with which we are not at present familiar. where the The material is pressed between the rollers of an old sugar mill; a cider press will also sutfice. The juice is run into the still (made of copper or lead), where a short boiling removes the oil which is eollected at the end of a copper con- denser ; the boiling juice is run through strainers made of brass wire into suitable wooden tanks, where it is neutralized with chalk of lime ete. During neutral- ization the mass is kept as hot as possible by means of a jet of live steam. ‘When the operation is complete the contents of the tank are permitted to settle; the clear liquid is syphoned off and run away, boiling water is added to the sediment, steam permitted to play through the mass; and after permitting settlement, the wash water is run away. The hot mass is now run into filter bags, which are securely closed, and placed in a convenient press (a cider press is sufficient). The expressed pulp is now placed on the driers, and when dry is packed into suitable containers, ele a ae Co) eee [FEBRUARY, 1909. ‘The drying is carried out in flat, deuble-jacketed pans, made of wrought or cast iron, which areso arranged that the pulp may be easily worked over with a spade and thoroughly dried. ‘The difficult part of the operation is to ascertain the point of neutralization, viz., that point when enough chalk or lime has been added to ensure full combination with the acid, and yet not enough to causea great excess. With a little experience this point is easily found by testing a sample of the contents of the vats. A sour taste indicates that the acid has not all been converted into citrate, and more chalk must be added. When the sour taste is replazed by a distinctly disagreeable characteristic taste, the acid has been removed from the liquor. ‘A further test is to take from the vat a sample of the clear liquor and also a sample of the sediment. If, when more chalk is added to the hot sample of clear liquor, effervescence takes place, there is still free acid in solution, ‘If, on the other hand, hot raw juice isadded to the sediment and decided effervescence takes place, there is an excess of chalk present.’ Appendix ITI. CULTIVATION OF LIMES AT MONTSERRAT. The following particulars have been supplied-by Mr. W. Robson, Curator of the Botanic Station, Monsterrat :— The plantations are chiefly confined to the sheitered valleys aud slopes of the lower lands. In addition to the natural shelter, belts of white cedar (Tecoma leucoxylon) are frequently used. This is practically the only plant used as a wind break, and it is planted at distances of about 150 yards, either in single rows or in double rows about 4 feet apart. Seeds are sown in small nursery beds and remain there until ready for trans- ferring to the field. No transplanting into nursery beds is done. In some instances planting is successfully done at stake in the field, when several seeds are sown at each stake and only the most vigorous of the seedlings allowed to grow. Showery weather is chosen for plant- ing, and small beds are made with a fork in which to put the plants. A distance of 18 feet by 18 feet is the most general for planting, although in the drier dis- tricts 12 feet by 12 feet is practised. For the first two years of growth, cotton has been successfully grown as a catch crop. FEBRUARY, 1909.) Hoeing isdone at intervals of about six weeks or two months, and in the dry season more frequently. The method of keeping a circle clean around each tree and cutlassing the remainder of the field is not adopted on Montserrat planta- tions. Appendia ITT. Exports oF LIME PRopUCTs. Details of the exports of lime products from the Islands of Dominica and Mont- serrat are given in this Appendix in tabular form. Table I. gives thelime products from Dominica for the years 1892-1895 inelu- sive. Exports of concentrated juice, raw juice for cordial, hand-pressed oil, distilled oil, pickled limes, and green _ limes are given. In addition to these, 222 gallons of lime cordial of a value of £33, and 733 ewt. of citrate of lime valued at £1,503 were exported in 1906, and 6,352 gallons of cordial, of a value of £958, and 2,388 ewt. of citrate of lime, of a value of £7,761 were shipped during 1907. These amounts have been included in the total values that are given for these years. There are also given in this table columns that show the total estimated crops of the several years in barrels of lime fruits and in gallons of lime juice. In 1892 itis estimated that 58,616 barrels of limes were produced, while in 1902 this had inereased to 249,178. In that year, however, a severe gale and attack of scale insects affected the lime cultiva- tions to such an extent that the crop of 1903 was nearly 50 per cent. less than thatof the previous year. A gradual recovery has been made since then, until in 1907 we find that the cropis estimated at 272,229 barrels. Table II. gives the exports of lime roducts for Montserrat for the years 1892-1907.

WHAT FORESTRY HAS DONE. The following extract is reprinted from Circular 140, Forest Service, U.S. Department of Agriculture :— (Continued from page 450, Nov. 1908.) AUSTRIA AND HUNGARY. AUSTRIA. In Austria, which has been independent of the German Federation only since 1866, forestry has, in the main, followed German lines. Austria-Hungary is one of the largest exporters of wood, and the yearly exportations reach 3,670,000 tons. Germany takes more than halt of tthe exports, and the rest is distributed to Italy, Russia and Switzerland. Austria has 24,000,000 acres of forest, of which only 7 per cent. belongs to the State and 58 per cent. is private land. Communal and entailed forests make up the remainder. Of the private forests 34 per cent. is in estates ranging from 20,000 to 850,000 acres in area, and for the last fifty years at least 75 per cent. of the total forest area has been held in large, compact bodies. These large blocks are naturally favorable to forest management. Private forestry is further encouraged by the system of forest taxation, which relieves forests in which forestry is practiced. In the United States there are many enormous private forest holdings on which forestry would unquestionably be practiced were it not that excessive or ill-devised forest taxation effectually discourages it. The total net revenue from the Austrian State forests is over $5,000,000. The net yearly revenue per acre of 21 cents is comparatively low, due mainly to the facts that only fifty-six cents per acre is expended upon the forest, and that most of the area is located in the rugged Alps and Carpathians, where administration and logging are costly. The present forest department was started in 1872 in response toa popular outery against the policy of selling State lands. That policy resulted in reducing the area of State forests from 10,000,000 to a little over 7,000,000 acres during the first half of the nineteenth century. The administration was re- organized in 1904, and now has three departments—administration proper, re- forestation and the - correction of torrents and forest protection. Forestry is successfully practised on 60 per cent. of all the Austrian forests and on 82 per cent. of the private forests, and excellent results have been secured by co-operation between the State and private persons in forest management, particularly under the law of 1888. The most conspicuous fruit of Austrian forestry, however, is the reforesting of the ‘ Karst.” The karst was a stretch of barren lands in the hilly country of Istria, Trieste, Dalmatia, Montenegro, and neighbouring territory along the shores of the Adriatic Sea. It comprised some 600,000 acres. Kor centuries it had furnished the ship timbers and other wood supplies of Venice, but excessive cutting, together with burning and pasturing, the evil results of clearing, and the natural condition of the land, had left it a waste almost beyond re- covery. Many laws had been passed from time to time to stop the forest havoe, but without real effect till 1865. In that year the Government, persuaded by the Forestry Association, began to offer help to landowners who would undertake forest planting, Taxes were remitted for periods of years, technical advice was given, and plant material as well as money was supplied. Further laws were found necessary in 1882 and 1887 to meet the objection of stockmen. - A6 the present time over 400,000 acres, or two-thirds of the Karst, have been brought under forest, in part by plant- ing, at a cost of from $8 to $10 an acre, in part by protection and the natural recuperation so made possible. This work has been carried on under the direction of the ‘‘forest protective service,” which was first created for Tyrol in 1856 as a result of floods in the Tryolese Alps in 1851, and was later (1871-1874) extended to the rest of the Empire. This service, which is distinct from the State forest administration, has also been especially helpful in encouraging private forestry. Though at first regarded with hostility, it is now held in high regard on the strength of the work it has done and is doing. Harmony of interest between the State and private forest owners, which the whole Austrian forest policy favours, is notably secured by the encouragement of the wood export trade through such provisions as reduced freight rates, the absence of export duties, and moderate forest texation. A ‘“‘reboisement” or reforestation law, based on that of France, was passed in 1884 to control torrents. - This law carries an annual appropriation of $100,000, and the planting work, like that FEBRUARY, 1909.}/ on the lands of the Karst, is carried on under the direction of the “‘ protective service.” For the regulation of the lower rivers $1,350,000 was appropriated at the same time, and of this sum $400,000 has been successfully expended on _ re- forestation. HUNGARY. Hungary has 23,000,000 acres of forest’ of which the State owns 16 per cent. ; corporations, 20 per cent,; churches, cloisters, and other institutions, 7'5 per cent,; 4nd private persons the remain- der. From $10,000,000 to $12,000,000 worth of wood is annually exported. About half of all the Hungarian forests are under working plans, by which the eut is regulated so as to provide for a sustained yield, and the present annual cut of 1,000,000,000 cubic feet is believed to be considerably less than the wood actually produced. The State forests yield $600,000 net annual revenue. The management of all co-operation and protection forests has been super- vised by the Government since 1879, and all so-called ‘absolute forest land,” in other words, land unfit for farming, must be reforested within six years after itis cleared. Three-fourths of all the forest land of Hungary, including private as well as_ public forests, falls under the classification of absolute forest land. Moreover, all mountain forests are required to be managed under State working plans. Two-thirds of all the Hungarian forests are brought under this sort of State supervision. Forest planting is encouraged by State nurseries, at which 10,000,000 seedlings are raised every year for free distri- bution and by bounties paid for forest Pen established on private waste ands. Hungary has some 600 square miles of shifting sands and waste lands, like those of the Landes of France. The work of reclaiming these was planned by the law of 1788. Actual planting was begun in 1817. By 1869, 20,000 acres had been forested, and parts of the planta- tions were beginning to yield a profit. The work of reforesting is constantly going on. NORWAY, SWEEDEN AND DENMARK. Norway. Only 21 per cent., or 20,000,000 acres of Norway is in forest. The State owns less than 2,000,000 acres of this. Of the forest region one-half has to import timber, one-fourth has sufficient for its needs, and one-fourth is able to export over 1,000,000 tons, valued at $18,000,000 a 19 161 Tinvbers. year. Nearly two-thirds of the exports goto England, and most of the rest is divided up between Belgium, Australia, France, Holland, Germany, and Den- mark. The total annual cut, one-fifth of which is exported, is about 500,000,000 cubie feet. It exceeds by 1,500,000 cubic feet the amount of wood grown by all the forest in the same time. In other words, the cut is far too heavy to last, so that a reduction of wood exports is inevitable, Forestry ic onalow level. The various provisions for the better use and pro- tection of the forests which began three hundred years ago, have been of too half-hearted a nature to meet the situ- ation. There is a forest service, but the officers are few and underpaid, and the districts under their care—sometimes several million acres to each—are far too large for effective work. Moreover, there are difficulties over the forest rights which were earlier granted to encourage the development of the country, but which are now greatly in the way of establishing property rights and organizing an administration. Since 1860 the State has been buying cut-over lands in order to plant them to forest where forest protection is needed, and from $15,000 to $20,000 a year has been spent in this way during recent vears. The communal forests are supervised by the Government, and are usually managed by the foresters with a view simply to supplying local needs. Sale outside the parishes are permitted only where there is more than enough for these needs. SWEDEN. Sweden has nearly 50,000,000 acres of forest, covering nearly 50 per cent. of the total land area. Since the English import duties were abolished in 1866, the wood exports from Sweden have steadily increased, till now Sweden stands next to Russia, the world leader, in wood exports with $54,000,000 worth a year, representing nearly 4,500,000 tons. England takes half of this, followed by France, Denmark, Germany, Holland, Cape Colony, Australia, and ..South America. The total cut from the forest " estimated to be near 1,000 million cubic ‘eet. The State owns about 13,500,000 acres, or 32:2 per cent., and controls 4,000,000 acres more. The State lands are, in the main, of lesser commercial value, and this fact, together with the existence of logging rights granted in the past, keeps the net income for the present down to 12 cents anacre, Nevertheless, Timbers, 162 since 1880 the net revenue from the State forests has risen from $300,000 to nearly $2,000,000 a year. Up to five hundred years ago Sweden was overburdened by forests, but by that time cutting and wasting had gone so far that the wilful setting of forest fires was forbidden. In 1638 overseers of communal forests were appointed in order to conserve supplies of wood for charcoal used in the iron industry. A general law followed in 1647, and a director of forests in the two southern districts was appointed in 1720. All through the eighteenth century restric- tions upon forest use were in force, Toward the close of the century there was, indeed, a premature scare over a possible timber famine. Yet, despite this legislation, and much legislation which followed, waste continued to go on. While measures were being passed to conserve the forests, the communal forests and town forests were actually being sold. It was not till the law of 1903, which went into effect in January, 1905, that a satisfactory policy was secured. In geueral, this requires the practice of forestry. Asin Russia, pro- vincial forest protection committees have to approve the local felling plans. A diameter limit is set, below which trees may not be cut. Clearings are forbidden and cleared land, unless used for other purposes, must be reforested. Pasturing is restricted where it would do harm. In the past thirty-five years the State has increased its forest holdings by 45 per cent. through the purchase and reforest- ing of wastes and sand dunes and by the settlement of disputed titles. The pur- chases amount to over 600,000 acres, for which an average price of $5°30 an acre was paid. Lumbering is carried on much as it is in the United States. The State, as a rule, sells stumpage, and the timber is i a ir [FEBRUARY, 1909. removed by contractors. Management is by no means so detailed and intensive as in Germany or France. The trees which are to be cut are marked, but no attempt is ordinarily made to prepare complete working plans. Only a moderate amount of planting is done to secure the future crop, and natural reproduction is mainly relied upon. Forest fires continue to do great damage, especially in the northern part of the country. A forest patrol is doing effective work, however, in checking the spread of fires. DENMARK. Denmark has about 600,000 acres under forest, of which the State owns over 23 per cent., or 142,000 acres. About 75,000 acres of wastes are in process of reforest- ation. The need of wiser forest use was felt in the eighteenth century, and by 1781 the State forests were placed under administration. But the clearing of the forest continued at sucha rate that in 1805 it was provided that the still exist- ing forests of beech and oak should be maintained forever. Further, provision was made as tothe selling of the pea- sants’ farms, so that they should not be accumulated in large holdings which the peasants would have to depend for their wood. Since 1820 the forest area has been increasing. At present reforesting is adding to it very considerably. Nearly 200,000 acres of heath have been planted in the last forty years. To this work of reclamation the State contributes $40,000 a year. In State forests, as well as i nthe com- munal forests and the farmers’ woodlots, forestry is carefully and profitably prac- tised.—Hawatian Forester and Agri- oul Faas.

From past observations and our ex- periences of the year 1907, with regard to Mosquito blight, it would seem that everything depends upon the climatic conditions prevailing during the first six or seven months of the year, whether the pest becomes serious or otherwise from about July onward to the end of the season. Without doubt the blight has this year been as serious as in any year since its first discovery, and in July reports began to come in from nearly every part of the tea districts that ‘* Mosquito” was damaging the bushes to such a degree, that certain gardens were practically closed for the remander of the season. This was’the case, not only in one corner of a district, but in several widely separated portions of the whole tea area, the blight generally being, on most gardens, worse than in previous years. In one or two instances only (where the insect had in past years given trouble) were the reports tavourable in that there had been no appreciable loss incrop. The following extracts from letters received from planters giving their opinions as to the reason for the current year’s excessive attack of Mos- quito blight are interesting and point tothe one idea that “ Blight” is con- trolled in a very great measure by climatic influences, — ONE CAUSE oF Mosquito BLIGHT. One Manager writes from Assam, under date the 24th September, 1907 :— “IT am of opinion that the cause of Mosquito blight appearing so early and in such a severe form this season is entirely due to weather conditions. The cold damp weather which prevailed during the months of May, June, and July, seems to have been especially favourable to the successful develop- ment of the pest, and were it not for the fotunaie occurrence ofa spell of sun- shine and heat in August which checked its progress, the loss of crop would have been considerable. As it is, I only estimate a loss of about 200 to 300 maunds, while in the last five years the loss has been nominal. Bar a few isolated patches, at the end of each season, the pest has done little or no harm here for the last seven years, [| may mention that the temperature for the last five years has not been so low in May, June and July, as it has been this year. My experience is that absence of sunshine is invariably favourable to the development of the pest.” Another planter writes:—This year is one of the worst in this district (Dar- rang) for Mosquito blight since 1902, the weather being socool and dull for the last three months until the 11th August when we had a change,” ete.. etc. It is quite certain that the attack of Mosquito as it appeared this year in the Dam-Dim district of the Duars could hardly have been worse, several gardens in the north-west corner of the district becoming practically closed towards the end of July and in August. On visiting these gardens in August it was found that manufacture had come practically to a standstill, leaf only being available from a few acres of tea. ‘‘ Gray blight ” in the case of oneor two estates was also greatly responsible for the closing of those gardens, and ‘‘ Red Spider” had helped in the first instance to weaken the bushes. The greater area of tea in that part of the district is planted with a low jat bush, which, asis well-known, is much favoured and first attacked by the blight. Those portions planted with the indigenous and better jats were last at- tacked, andin some instances blocks have been left almost entirely free from attack, although situated in the centre of the affected area. This, without doubt, points to the advisability of gradu- ally uprooting the poor jat hybrid bushes and by replanting with high- class materials. : EFFECT OF SCARCITY OF LABOUR. The scarcity of labour in that part of the district did not permit of * thinning out” the bushes at the pruning season, and itcan, therefore, be easily under- stood, when the nature of the growth of China hybrid and low jat bushes is con- sidered, that the mosquitoes had a sure place of refuge in the heart of the bushes where very little could get at them to destroy them. The _ iusects sheltering in such a place would be en- tirely protected from wind and rain. Storms, which were this year of a very mild nature, did not destory wholesale Plant Sanitation. 164 the newly-hatched out bugs as would have been the case in seasonable weather, and if the bushes had been thinned of some of their branches and useless twigs. It was particularly noticeable on one of the gardens in the district where some replanting had been done with high-class tea that the young plants were practically untouched by the mosquito, although the block was right in the centre of the block with the blight, and to all appearances closed for the season. There seemed to be no reason why these young plants should not have been attacked, even toa small degree, as the mosquitoes must have been starving on the surrounding tea, but the fact that the replanted area (10 to 15 acres?) was not attacked helps to confirm what has been written in the above paragraph, namely, that the bushes on the replanted area, although showing plenty of foliage and offering food for apparently starving in- sects, had—first, no unnecessary wood about them,and second, no cluster of closely growing stems near to the ground like the surrounding poorer jat tea, thus allowing the passage of light and air through their whole system of branhces. No immature mosquito can live on a bush under these circumstances, as wind and heavy rain alone would des- troy them. This isin support of the suggestion that those gardens subject to attack by Mosquito blight, should, in the first instance, do special careful ‘‘ thinning out” at the pruning season in order that the severer storms of wind and rain may kill off the greater number of young freshly-hatched-out mosquitoes and en- able spraying with Kerosine Emulsion and the catching of the insects by coolies to be carried out more effectively. Tur Use oF KEROSINE EMULSION. This brings me to the matter of spray- ing with Kerosine Emulsion. Up to the present no better remedy than this, to- gether with the collecting of the insect by hand, has been found,; and it is my opinion that it will be along time before a better remedy will be discovered ; but at the same time I do not think spray- ing with Kerosine Emulsion has, on any garden, been carried out ina thorough and proper manner. Alsolam perfect- ly sure that there are many gardens which have spent thousands of rupees every year in spraying with Kerosine Emulsion without realising any appreci- able benefit from the process. When the habits of the tea mosquito, as given (FEBRUARY, 1909. below, are taken into consideration, I think this will be brought home to many, and the following may be of use in the future treatment of the pest. The general custom cf insects, on being disturbed, is to retire to places of safety, and this is particularly the case with the tea mosquito. Where the mos- quito occurs, so long as the bushes are not thoroughly cleaned out at the time of pruning, the difficulty of eradicating it will be realised. In spraying, no soon- er does the spray touch tke bush than the insects either fall to the ground or retire into the heart of the bush, where, according to the way in which spraying has been done inthe past, the insecti- cide does not reach all of them. Every- thing, therefore, depends upon the manner in which spraying is conducted, and, provided that a thorough cleaning- out of the bushes has been carried out in pruning, the emulsion will be able to reach every part of the bushif applied as now suggested. Itis not sufficient to only spray the top and sides of a bush, it must be thoroughly saturated with the solution—the leaves, both upper and lower sides, the stems, the soil and “Jabra” at the foot; and the nozzle of the sprayer should be placed right in- side the bush, the spray being directed ~ upwards. The bushes cannot be too much _ saturated. It is so important that the upper side of the leaves should be spraycd upon more than a very little, because each leaf acting as a drain, the liquid runs off one on to the next below, and so on till it reaches the ground round the outside of the bush. This is almost an entire waste of material, as the insects have by this time left the surface of the bush and will be found in the centre of it or at the collar in the “Jabra” at the foot. The young flush must, of course, receive the spray, and that thoroughly. WHEN TO SPRAY THE BUSHES. Better results will be obtained if the spraying is conducted during the heat of the day, when the insects, both im- mature and adult, are protecting them- selves from the sun, inside the bushes, and it goes without saying, of course, that the freer a garden is of jungle at the collar of the bushes the better will be the effects of spraying. To thoroughly saturate the bushes and the “Jabra” atthe foot of them with the mixture, in the manner. above sug- gested, the cost of spraying per acre will become rather more expensive than for- merly, but this can partly be remedied by adding more water to the mixture, Frprvary, 1909] which atthe same time will be a wise procedure owing to there being a certain amount of risk in burning the bushes by saturating them with the liquid atits usual strength. Further, if this thorough style of spraying be carried out, I think it willbe found that very much less money will be required for collecting the insects by hand. This manner of spraying should be done at least twice in the year if not more frequently, and if one application is not found sufficient—at the usual time after pruning when the bushes are first breaking out, and again, if one necessary, about one month afterwards. So soon as the insects are noticed to be feeding and are about in any numbers, then is the time to spray thoroughly without sparing the liquid. AN IMPORTANT POINT. An important point to observe in deal- ing with an epidemic of this kind is to thoroughly treat the whole of the affected area in the space of afew days, as the quicker the “ round” ofthe garden is made, the more thorough check will it be to the deposition of eggs. In the life-history of the Tea Mos- quito it may not be known that the feeding period of an individual lasts for 2} months. Without taking into consideration the hybernating period of the insect during the cold weather months, mature or winged individuals kept in captivity in the Insectarium at Kanny-Koory, lived for 62 days, and if we add to this the period spent in the immature or larval form, which is roughly 10 days, we find, at the height of the season, a single insect lives for quite two-and-a- half months. Add to this the fact that an insect will make as many as 125-150 punctures in the leaves every 24 hours, and the damage done to the bush can be imagined.—The World, December, 1908. DEVELOPMENT Or DISHASE- RESISTANT VARIETIES OF PLANTS. By H.S. Jackson, Newark, Del, [Given before the Massachusetts Horti- cultural Society, March 14, 1908. | While the subject which I have selected may not be of special local interest, I believe it to be of sufficient general interest to merit a discussion before any body of men interested in any branch of agricultural science. In the entire discussion of the development of disease-resistant varieties, | may not 165 Plant Sanitation. mention any special crops which are of particular interest to Massachusetts Horticulturists, for this phase of plant breeding is not sufficiently developed as yet toenable us to direct the grower how to proceed to obtain results, except with very few crops. The study of the development, by man, of disease resist- ance in plants is yetinits infancy. propose to discuss the subject in general, and to give a review of what has already been accomplished by horticulturists and plant-breeders in developing plants resistant to specific diseases. We must first get a definite idea of what is meant by disease resistance in plants. We must distinguish it from hardiness. Hardiness is a general term. A hardy variety, as generally considered, is merely one that is less susceptible to cutting frosts, drought, or extreme changes in temperature; in short, one that is capable of withstanding adverse climatic conditions in a state of health. A disease-resistant variety for our present purpose may be defined as one that shows resistance to the attack of a specific disease due to a_ specific organism. In this age of intensive agriculture, with our advanced and _ increasing knowledge of the principles of culture and fertilization of all sorts of agri- cultural crops, the question of the health of the plant is recognized as one of paramount importance. We know that under certain conditions, if we give our plants the proper food and the proper cultivation, we may expect a reasonably healthy crop. Neglect these factors and we know that we may expect an un- healthy crop. We know that soil, plant- food culture and weather conditions all have their influence on the health of plants. We have come to learn, however, that we cannot control many specific diseases by cultural methods. We must resort to spraying and seed or soil treatment of various kinds. We know that we can control apple, scab bitter rot of apples, black rot of grape, and many _ other similar diseases with Bordeaux Mixture. We have come to realize that spraying of certain crops is a necessity to success- ful culture. The successful apple grower sprays as faithfully as he prunes. The successful potato grower, in sections where late blight of potatoes is pre- valent, sprays as_ regularly as _ he cultivates, and is always assured of a crop. The farmer who wishes a crop of oats free from smut knows that he may obtain such a crop by proper treatment of seed before planting. The market gardener who grows cabbage with the Plant Sanitation. best success knows that he must treat his cabbage seed with formalin or corrosive sublimate as a precaution against the introduction of the bacterial rot. There are a host of diseases which might be mentioned for which some specific treatment is in common practice. Why then is it necessary for us to have resistant varieties? Spraying is a nuisance at best, and any man who has had any actual spraying to do would ladly eliminate this not inconsiderable item of labour and expense. The second reason is that, while spraying may be profitable for the large grower, parti- cularly the man who makes a speciality of some one crop, it frequently is not profitable for the small grower. The man who grows afew apple trees, a few acres of potatoes, tomatoes, cucumbers and other vegetables in proportion, frequently has to give up the cultivation of any crop that is repeatedly attacked by aserious disease. Spraying frequent- ly is not profitable for men who carry on diversified farming. I do not wish to be misunderstood in this connection. When the mere item of added expense of materials and labour necessary to the spraying alone is considered, we will nd that spraying is profitable in most cases even for the small grower. The labour question, however, adds another factor. When it is possible for the small grower or the man who carries on diversified farming to obtain addi- tional labour of the right sort at any time, he can spray his various crops with profit, but when labouris limited and the grower must depend on his steady labour todo the spraying, he will usually find that to carry on the work properly other important things must be neglected. Spraying must be done at the right time, or itis of no value. The third reason is that there are many diseases which experimentally can be controlled, but not profitably. Asan example, we may mention the rust of wheat and many other diseases of fieldcrops. The fourth reason is that certain very serious diseases have never been satisfactorily controlled even by experiments. To this class belong such diseases as peach yellows, crown gall, and various soil rots and wilts. plants belong to this class. METHODS. In order to develop varieties resistant to disease, several methods of work are open to the investigator :— (a) Selection of individuals. (6) Selection of varieties. (c) Hybridization followed by selec: tion of varieties and individuals, Most bacterial diseases of | 166 (FEBRUARY, 1909, SELECTION OF INDIVIDUALS. Every grower of plants has doubtless observed that in a field of a crop suffer- ing from an epidemic disease, certain individual plants may show more or less resistance to the disease. By selecting seed from such plants we would expect, if the resistance is an actual one, to have offspring which would inherit the character of resistance. By repeated selection through several generations, always saving seed from the most healthy plants, we would expect to gradually develop a variety or strain much more resistant than ordinary one. This has been practically tested in a number of cases and found to be success- ful. Mr. P. K. Blynn, of the Colorado Experiment Station, has obtained most satisfactory results by this method in selecting a strain of cantaloupe known as the pollock strain, resistant to the very serious leaf spot disease due to Macrosporium cucumerinum. SELECTION OF VARIETIXS. In order to obtain results by this method, all the vatieties of a crop obtain- able are grown on infested ground in order to study their relative resistance to disease. Experimenting in this way some variety may prove exceedingly resistant to the disease in question and further work rendered unnecessary except to keep the variety pure. Usu- ally, however, all commercial varieties will be more or less susceptible. If such is the case, then the varieties least sus- ceptible must be studied further and selection of individuals proceed as in the first method. 1 believe that the most certain and best results are to be obtained by combining the first method with the second. That is, select the most promising varieties with which to practise individual selection. HYBRIDIZATION. In case no varieties give promise of resistance, hybridization, or crossing, may give satisfactory results. It fre- quently happens that wild species which may be worthless commercially, but closely related to cultivated forms, show marked resistance to diseases which seriously attack the latter. Sometimes we may havea variety which is worth- less commercially, but which is known to be strongly resistant. If such a resistant species or variety be crossed with a profitable commercial variety, and a close study of the resulting off- spring be made, some desirable new variety thus produced may show marked resistance. A notable example of this method of procedure is the work of Mr. W. A. Orton with water melons, iis: aie BY at OURS as a Sb FEBRUARY, 1909.1 Water-melons in the South are seriously attacked by a soil disease (Neocosmos- pora), which it has been impossible to combat satisfactorily. Mr. Orton first made a study of all varieties of water- lemons and related plants obtainable, and found that all commercial varieties were almost equally susceptible. He found, however, that a form of citron (hard fleshed melon) was very resistant, but worthless commercially. He crossed this with commercially desirable varie- ties. The seed resulting from this cross, when planted the next year, re- vealed the fact that he had obtained about a thousand new varieties, most of which were either worthless commer- cially or non-resistant. He selected a few of the most promising of these for further study, and found that he had one variety commercially desirable, profitable, and strongly resistant, WHAT HAS BEEN DONE. Let us see what has been accomplished toward obtaining practical results in the breeding or selection of disease-proof varieties. I will speak briefly of some of the most notable results obtained in this country or applied to American con- ditions. It is not my purpose to review the observations (and they are many) on resistant varieties of vegetable or fruits that are in common use, but to confine myself to a discussion of the outcome of definite efforts to obtain varieties resistant to specific diseases. WHEAT. We will agree that to spray a wheat field for rust would be out of the ques- tion from a practical standpoint, even though such treatment might rid the crop of the disease. It is evident that in sections where wheat rust is especially prevalent, disease-resistant varieties of wheat would be of special value. Inves- tigations have been made in Kurope, Australia, and the United States for the purpose of obtaining rust-resisting wheats. More or less success has been obtained by all investigators, Carlton, working in this country, has made a study of all available varieties from all countries and has found that certain varieties of the Durum wheats are most resistant to the black stem rust. In this connection the recent work of R. H. Biffen on the hybridization of wheats bids fair to have a far-reaching influence on future work in developing immune varieties. Hefound that susceptibility and immunity in certain varieties of wheats are definite Mendelian charac- ters, the former being the dominant one. CLOVER. Messrs. Bain and Essary of the Ten- nessee Hxperiment Station have con- 167 Plant Samtation ducted experiments in selecting and developing a variety of red clover resist- ant to a new fungus disease belonging to the anthranoses, that has for several years threatened the cultivation of red clover in Tennessee and the South. They have practised selecting seed from individual plants which survived in a field very seriously attacked by the disease and have obtained very satis- factory results. Cow PEA. This plant suffers in the South from two serious troubles, a wilt disease and a nematode root gall. Varieties have been studied and the Little Iron cow- pea has been found to resist the attack of both these diseases. POTATORS. Various potatoes resistant to the late blight have been known for many years in Europe. Recently the study and selection of resisting varieties have secured considerable attention in this country. Jones and Stuart, working at the Vermont Experiment Station, have had very favourable results in selecting varieties resitant to this trouble. The work on potatoes resistant to this disease has been largely a study of varieties. Itis still in progress, In con- nection with the work with late blight attention has been paid to sorts resis- tant to scab. The Ohio and other Sta- tions have had marked results in select- ing varieties and individuals resistant to the early blight (Alternaria) which is not easily controlled by spraying. TOBACCO. This crop is attacked in Connecticut by a serious wilt disease. By selecting seeds from individuals which have sur- vived in a field nearly totally destroyed by the disease, Shamel and Cobey have succeeded in developing resistant strains. A similar disease in North Carolina has been investigated in the same way with very favourable results. This plant is also attacked by Nematode worms, which cause gall-like swellings on the roots. Experiments are now underway by officials of the U.S. Department of Agriculture for the selection of varieties resistant to this trouble. COTTON. Very satisfactory results have been secured in selecting varieties resistant to the wilt of cotton in the South. The work has been carried on by W. A. Orton of the Department of Agriculture. He has found that several varieties of Egyptian cotton, as well as one Upland cotton, give great promise of resistance. Plant Sanitation. He suggests crossing the different resis- tant sorts, especially resistant varieties of different races, with the hope of obtaining varieties which will combine the good qualities of both races. Mr. Orton’s investigation of cotton resistant to the wilt fungus revealed a very important fact. He found that even with the most _ resistant sort grown on infected land, infection occurred in the rootlets, but the fungus was notable to gain entrance to the main root system, and therefore could not spread in the plant. The resistance, then, in cotton to the wilt fungus is not caused by some peculiarity of the root which prevent the entrance of the fungus into the tissue, but to some undetermined character which prevents the spread of the fungus toany extent after it has gained entrance to the tissue. W ATER-MELON. \n account has already been given of the success of Mr. Orton in obtaining a wilt-resistant variety of the water-melon by hybridization with the citron. CANTALOUPE OR MUSK-MELON. The work, previously mentioned, of Mr. P. K. Blynn, special agent of the Colorado Station, in developing the Pollock strain of the cantaloupe resistant to leaf spot disease due to Macrosporium is especially notable, as it is, perhaps, the most successful attempt yet made in this country to develop a variety resis- tant to a leaf parasite. The strain is a result of careful selection of seed from resistant vines. ASPARAGUS. It is well known that the Palmetto variety of asparagus is especially resist- ant to rust. It is, however, not a desirable variety for canning. In Cali- fornia, R. E. Smith of the State Experi- ment Station, is engaged in developing a variety which will combine rust resistance with the qualities desired by canners found in the Conover’s Colossal. VIOLET. Violets grown in greenhouses are especially subject toa leaf spot disease known as Alternaria viale. Itis known among violet growers that the Lady Hume Campbell variety is the most naturally resistant variety in culti- vation. This natural resistant has been greatly increased by carefully selecting the most resistant plants from which to propagate. FRUITS. Little work has been attempted to de- velop disease-resistant varieties among 168 (FEBRUARY, 1909. the fruits. As Ihave previously stated, the development of disease resistance is a comparatively new undertaking for plant-breeders. That is,it has beena relatively short time since horticul- turists and plant-breeders have under- taken, with a definite idea in view, to develop varieties resistant to specific diseases. Perhaps this is why little work has been accomplished among the fruits. Obviously it would take a longer period to obtain results in developing varieties of perennials than annuals, and the plant-breeder will naturally select for study those problems which give promise of solution in the shortest time. It is, however, a matter of common observation that some varieties of cur tree fruits are more resistant to certain of their maladies than others. For example, in Delware, it is known that among apple varieties the Lily of Kent is above all others most resistant to scab and bitter rot, while the Jonathan is especially susceptible to rot. The whole Winesap group is said to be relatively resistant to rot but susceptible to seab, while the York Imperial is resistant to scab. Among pears the Keiffer is known to be resistant to fire blight, while the Bartlett and others are very susceptible. A host of such observations might be cited to show that among our tree fruits | there is varietal variation as regards resistance to disease. There are some diseases of tree fruits which are especially troublesome and impossible to combat satisfactorily, for which it would be highly desirable to have resistant varieties. I refer parti- cularly to the peach yellows. The observations of Professor E. W, Morse. reported in the Bulletin of the Bussey Institution, indicate that individual peach trees from which to ‘propagate may be found which are resistant to yellows. Since no satisfactory method has ever been tound to combat. this dread disease, the study of the problem of prevention from this standpoint is highly desirable. Another disease of great importance is the crown gall of raspberry and black- berry. This is a very serious trouble in infested districts. In Sussex County, Delware, the raspberry industry, once very large, has been practically wiped out by this trouble. Since the organisms of the disease are retained in the soil and attack the roots or crown only, no preventative measures are practicable. It seems highly desirable to attack the problem of the treatment of this disease by the selection .or breeding of disease- resistant varieties. ; (To be comtinued.)

In view of the popularity attained amongst cultivators throughout India by the anti-rinderpest inoculation treat- ment, the demand for serum has_ be- come larger than the Muktesar Labor- atory can meet. Steps, therefore, are being taken to ascertain the feasibility of establishing an independent laboratory in the Madras hills, where the serum for South India could be manufactured.

PIG FARMING IN BRITISH EAST AFRICA. A REVIEW. We have to acknowledge the receipt of a nicely got up booklet entitled ‘‘ Pig Breeding and Feeding in East Africa” by J. EH. Prossor, adviser in Swine Hus- bandry and Bacon-curing to the Uplands of Hast Africa Syndicate, who has devoted his life to this branch of farm- ing. The author, in transmitting the work, writes:—‘‘I have been looking into the figures giving the quantity of bacon imported into India—over £70,000 annually—and it has struck me that a country like India should grow its own pork as the heat suits pigs in this country (British Hast Africa), and, now that refrigeration has been brought to its present standing, there is no diffi- culty in curing in any climate or at any temperature. I shall be glad to exchange any information with you.” Pig rearing has, so far as we know, never been taken up as a serious busi- ness in the Island; but, judging from a perusal of Mv. Prossov’s work, there would seem to be no reason whatever why it should not prove a successful venture. No systematic farmer in any country is without pigs. In Ireland the pig is look- ed upon as ‘‘ the gentleman who pays the rent” ;in Denmark as ‘‘the Savings bank.” In America, pigs are found to pay when other animals do not, proving there and elsewhere ‘‘the farmers’ friend.” As regards East Africa, after a careful study of the conditions, Mr. Prossor says: ‘‘ITam certain that once the set- tlers knew that they have a regular and sure market, provided they breed and feed the right sort of pig, they will find that there is no class of stock that will pay them better and turn over the cost ina shorter time.” And in his book Mr. Prossor proceeds tc instruct the reader on all matters connected with selection, feeding, &c, so that one cannot go far wrong if he carefully studies the facts and figures in the manual referred to. In Ceylon there would appear to be as great facilities in the matter of food, &c., as in the colony regarding which the expert re- ports.

Weare all familiar with the phrase, ‘A little farm well tilled.” That short sentence describes the modest wish of everyone who launches intoan agricul- tural career. Having got the ‘‘little farm,” the wish expands into a ‘big farm,” and, by keeping the “ little farm” well tilled the “big farm” may become an accomplished fact. Tillage in agri- culture isa most important operation, its object being, of course, to bring the ground into that state of tilth best suited to the growth of grass and crops. In order to obtain this tilth, the employ- ment of many kinds of implements are required, and the first of theseis the plough. Itis not now regarded as the most important, because the cultivators, grubbers, disc harrows, and similar im- plements reduce the ground toa proper condition fora seed bed, even if the ploughing has been badly done. There can be no doubt, however, that the plough isa very important machine in agriculture, and must continue to beso till the end of time. It is the most ancient implement known, but within the last century it has been improved very much indeed—in fact, there are few machines which have been more altered in its appearance and in its work. Wood has been replaced by iron; steel has taken the place of iron ; and mechan- ical laws have been applied to make the implement easier to pull and more effective in its work. As the years go on, new principles are being applied, and there are now quite a number of different kinds of ploughs on the market and in general use. There are the ordi- nary single and double furrow ploughs (swing ploughs are rarely seen now- a-days), digging ploughs, subsoil ploughs, gang and stump-jumping ploughs, one- way or hillside ploughs, multiple ploughs, and, last of all, disc ploughs. Some of these, as their name denote, are special-purpose ploughs, and with these there is no necessity to deal in the present article. Single-furrow ploughs are not used except on small holdings and in gardens. They are now fitted with wheels, which keep them steady and at a uniform depth. Swing ploughs are balanced by the ploughmen, and require more skill in their management than wheeled ploughs. Single-furrow ploughs are often used for opening lands or striking out, and also for finishing. They are also used for such work as potato-plant-. ing ae ough the double-furrow is also used. The double-furrow plough has for long time been the principal kind o plough used in New Zealand. It is now in some districts being superseded by the treble-furrow, which is in reality a double-furrow with another beam and mould-board attached. The principle is exactly thesame. The idea of the extra furrow is to give the larger teams, which must be used in cultivating and drilling, sufficient work todo when ploughing. It is not so long ago that three and four horse teams were in vogue. Nowa days the five and six horse team is in more general use, because of the extra strength required to haul up-to-date cultivators, disc harrows, and drills. Then, again, dig ger and disc ploughs are being used very largely, and _ these demand larger teams than the old four horse team. A plough is, in reality, a combiration of instruments fastened toa beam. The most important of these instruments are the coulter or skeith, the share or sock, ~ the mould-board or breast, and the bridle, Other parts are added, accord- ing to the kind of plough desired, but usually there is a lever and a steering- rod. It is not necessary for me, I suppose, to describe the function of each of these parts. Before describing the different kinds of work done by several kinds of ploughs and the uses of each, I will give a few of the terms used in ploughing. There are two principal methods of ploughing—viz., in landsand round-and- round. The former method is used on flat land and on undulating downs, while the latter is used in steep localities. With practice, a perfectly straight furrow may be maintained, and witha little patience almost ary plough may be set to cut and throw all its furrows alike and evenly. The turning-voints at the ends of the ‘‘lands” are called ‘“‘headlands,” and it is important that youths starting to plough should be taught to keep their furrows square with the headland, and the headlands them- selves the same width right through. A plough cannot do good work uuless it is kept in good order, and every ploughman should know how to keep his plough wheels packed and his skeiths running true. For skeiths, I find the ‘‘cones” the best kind of axle to use. Skeiths Reka a aT bat aad y FreRuARY, 1909.] ved should not be used among stones, nor should they be used in frosty weather, as they are liable to get damaged very seriously. The ordinary double and treble furrow is mostly useful for loughing in the autumn, when it has to Be fallow through the winter for turnips or oats in the spring. Lea ploughed for wheat should be turned the round-and- round method. In this case it is a lazy man’s method. It continually moves the land towards the fences, while denuding the finish in the middle of the paddocks of soil. This applies also, of course, to ploughing steep country round-and-round, but it is unavoidable in this instance. By ploughing in lands, good drainage may be effected ; the land ean be effectually cross-ploughed, and the land can be kept fairly even and level by altering the place for striking out.and finishing. The crown of the land is the high ridge formed by marking out, or striking out, as it is usually ealled. This marking out is called “feeding.” The open furrow between the lands is called the ‘‘finish.” The furrows may be either gathered towards the crown of the land, or they may be scattered till an open furrow or finish results. In gathering, the team pulls to the right; ‘‘gee-back” is the command given by the ploughmen. In scattering, the horse turns to the left, or ‘come here,” as their driver would say. There are also several kinds of furrows, chief among which is the rectangular furrow, made by a fat-cutting share and an upright coulter or skeith; a high-cut furrow, obtained by using a share raised on the wing side, and a skeith or coulter, cutting a furrow at an angle. The digger plough has a furrow peculiarly its own, which I will attempt to describe later on. I have said that the single-furrow plough is very frequently used for marking out and finishing lands. This operation may, however, be done equally well with a double or treble furrow plough; and there are very few who now trouble with a single furrow for marking out. Some prefer three horses for striking out witha double furrow, but it may be done, with practice, with any team. Now that the seed is usually drilled instead of being sown broadcast on the furrow, there is not somuch used from the utility point of view for straight ploughing. Ploughing matches are going out of fashion, except in parts of South Canterbury and Southland, but it would be wellif our agricultural and pastoral societies took the matter up. Stubbles ploughed from autumn oats should be ploughed with an ordinary double-furrow or with one of the many 1 Scientific Agriculture. kinds of multiple ploughs now being used. These multiple ploughs are princi- pally useful for stubble work, and for turning over land out of turnips for either rape, grass, or oats. Oats are shallow-rooted, and therefore the digger may be reserved for the deeper-rooted wheat. Sometimes a mistake is made by ploughing too deeply for oats and for turnips. dry season comes, and the roots fail to reach the subsoil, Had the land been ploughed fairly shallow, say three or four inches, the roots would have reached the stored-up moisture, and would have givena good crop. Moreover being shallow rooted, they get the benefit of animal droppings and decaying vegetation when the furrow is fairly shallow, and also of the work of soil bacteria which are always more active se the surface than lower down in the soil. I have mentioned digger ploughs several times, and will now endeavour to describe them and their functions. They are daily coming into more extend- ed use, and in parts of Canterbury and Southland are thought very highly of indeed. Personally, I may say that some ten years ago I tried them, but was disappointed at the result, and gave them up. Some half-dozen years ago we had some very wet seasons, and I found that the digger would work where the ordinary plough would _ not. They left the ground in good condition for sowing grain on, and the crops did well. The secret of the whole matter was that the ploughs were being worked at too greata depth when they were previously being used. The breat or mould-board has a kind of shin on it which acts as a coulter, A skim coulter takes the place of the usual skeith or long coulter. This skim coulter assists in cutting the furrow, but most of the vertical cutting is done by the shin on the mould-board. The horizontal cutting isdone bya broad share, which forms the forepart of the mould-board. The shape of the mould- board is different to that on the plain double-furrow. It is much shorter, is slightly disked, and then takes an out- side curve. The earth is thrown out- wards and over, and is not compressed or packed. It is left in much the same condition as it would be if dug witha spade. The land _ lies loosely, and frost can get into it. The water runs through it, and there is no solid furrow to be worked down. As I have already in- dicated, the digger can be worked in stiff, clay soils in wet weathe1, when the plain plough would have to remain idle. It does a great amount of after- cultivation. A stroke of the tines or discs before the drill, and a couple of Scientific Agriculture where in other cases scarifiers and rollers would have to be used. The digger buries grass and weeds deeply down, so that they do not get a chance to grow through the furrows. More- over, the vegetation gets rotten about the time the ear of cornis filling, and helps materially to form food for the plant at a time when it requires it. There is, as already stated, a danger of turning up too much sour land, so that the seed does not grow away quickly. This must, of course, be guarded against. The plough will plough no deeper than where itis set. I know of people who quickly discard the digger because they cannot make them do good work. The fault is, very often, that an attempt is being made toturn overa furrow too wide for the depth. The resultis that the desired crumbling, feathery state of the land isnot attained. As a rule, people do not, on clay lands, desire to plough deeper than 6 or 7_ inches. Roughly speaking, 1 inch of depth re- quires 2 inches of width. Thus a furrow 6 inches deep should not have a greater width than 12inches. A furrow 6 inches by 15 inches would bea failure, in my experience. In marking out, the front wheel should be lowered in order that the front plough shall not plough too deeply, and throw up too higha ridge. In finishing, much the same method is adopted as with an ordinary plough. It is well to repeat that the first time of ploughing must not be too deep. The soil on the top after ploughing is all brought up from the bottom of the furrow. A paddock may easily be spoiled for a year or two because of too deep ploughing with the digger. They are often spoken of as horse-killers, but, as a matter of fact, they are not more so than an ordinary plough. They certainly require more strength, but they will turn over four acres a day, where an ordinary plough will only do between 3and 33 acres in the day. In ground where they have never been used before, the work is harder than on land where they are frequently used, because there is a certain amount of subsoil to be turned up for the first time. In ordinary cases five horses will work them as easily as four will work a plain plough, and, asI have said, they will do from half acre to one acre more work. The mould-board is shorter, but there is less friction, because it hasonly to clear its way, whereas a plain plough has to be dragged through the ground like a wedge. {shall conclude by saying something about the latest pattern of plough—the disc plough. They are coming into use slowly, and are excellent for certain 172 [FEBRUARY, 1909. kinds of work on certain kinds of land. For cross-ploughing in autumn they do good work, breaking up the ground thoroughly so that but little after-work is needed to make a good seed bed. They do well on stubbles in the autumn, and get overalot of ground in aday. They are made somewhat on the principle of the disc harrow, and require more power than an ordinary plough. If they are set narrow, and the ground is level, four horses will make them on stubble, turnip land, or fallow, and five on lea land. Generally speaking, however, they require five horses for the former kind of land and six on the latter, especially if the ground is hilly. They ave not suitable for turnip land which has been tramped and poached by stock in the winter, as they leave the ground too lumpy and rough. It is on _ the twitchy land that the disc plough is most serviceable. In fact, it will throw about land infested with couch, yarrow, and other plants with creeping roots in splendid style, where a plain furrow plough will scracely touch it. Paddocks which have been given up as unworkable, by reason of a mat of twitch or couch, have been brought into eultivation again by thedisc plough. It throws the furrows in the air, and leaves them lying uy to the sun and weather in such a manner that the plants are half-killed before after-cultivation is started upon. Moreover, the furrow, instead of being packed hard, so that no disc harrow or cultivator can touch it, is left so that these implements can smash them about splendidly. Some farmers break up twitchy land with the ordinary plough, and then put the disc plough on to cross-plough, with very satisfactory results, In my opinion, the disc plough is an implement that materially reduces the fear that twitch and couch, and such like weeds will utimatelv get possession of our arable lands,—A NEw ZEALAND FARMER in “The New Zealand Farmer,” —Queensland Agricultural Journal, Vol.XXI., Part 4, October, 1908. THE DUST MULCH. Direct evaporation from the soil can be checked by keeping the upper 2 or 3 inches of the surface well cultivated, soas to form a dust blanket, or dust mulch. When the ground is kept covered with a thick layer of dry, loose soil, evaporation is slight, but when the soil surface is not kept dry and locse, evaporation goes on very rapidly. The tools required for maintaining the dust mulch are a common harrow, a weeder, and various forms of cultivators. The strokes after, is all that is required, Frsrvuary, 1909.] fact that the soilin the vicinity of San Antonio is heavy, together with the comparative rarity otf high winds, makes it possible to maintain an effec- tive dust mulch and to accumulate in the soil enough moisture to carry ona crop to maturity even if little rain falls during its growth. _ After the dust mulch has been des- troyed by a rain, evaporation from the supply of water in the soil begins as soon as the rain ceases, and in cases where the weather immediately follow- ing the rain is hot and windy this loss of moisture becomes exceedingly great. On the heavy soils of San Anto- nio a light rain, as for instance 0°1 to 0°4 inch, reduces rather than increases the 173 Scientific Agriculture. total amount of soil water. This is apparently due to the fact that such light rains are only sufficient to establish capillary connection between the sur- face soil and the moisture in the lower soil, and before the surface is dry enough to permit cultivation some of the moisture has been drawn from the supply below and dissipated into the air. A rain of less than 0:1 inch is usually sufficient to establish such capil- lary connection, and is therefore harm- less. Even a heavy rain, unless followed immediately by cultivation to renew the dust mulch, may result in a reduc- tion rather than in an increase of the amount of soil moisture. Such a case is illustrated by Table 1.

APPLICATION TO COCONUT CULTIVATION. Is it more profitable to use famyard manure—i.e., cattle and other dung mixed with straw, waste herbage, and refuse properly decomposed in a pit— than artificial is a question that should be of great interest to all planters and agri- culturists. Artificial or special manures contain but few of the constituents re- quired for plant nutrition, and are applied to those crops which require more of a certain ingredient than the soil contains. Farmyard manure on _ the other hand is a general manure, con- taining all the constituents required by plant life. Artificial manures are much quicker in action than farmyard, and are an essential auxilary to general manures. A general manure may be used year after year on the same land, but artificials, if used exclusively, would Scientific Agriculture. 174 ultimately exhaust the soil. | The minimum of any one essential ingre- dient rules the crop. Jt does not matter how great a quantity of the other con- stituents may be present, good crops cannot be obtained if one substance is deficient. When this is the case a special manure produces as good effect as a manure containing everything necessary to plant growth. The world’s experience has proved that it is not advisable to continuously apply_ farm- yard manure. If a field was dressed every year with farmyard manure, after a timethere would bein the soil constituents more than are necessary, and a large store of fertility would have accumulated. And though the field may be said to be in a high state of fertility crops will not prove as _satis- factory as might be expected. This is because alarge quantity of food is LYING IN A DORMANT CONDITION in which state plants cannot assimilate it. In such cases a special manure which would convert dormant material into active matter suitable for plant nutrition is valuable. Instances of the above are sometimes seen in land in high condition from previous manuring. Asa rule an application of nitrate of soda will cause the crop to grow and bear vigorously, the plants making use of the hitherto dormant matter. The difference betweer the nitrogen in the nitrate of soda and the nitrogen in farmyard manure is that in the former it is immediately available and is taken up at once by the roots, whereas in farm- yard manure the nitrogen is partly locked up and is only made use of as it becomes available. The effect of a dressing of nitrate of soda is not seen beyond the cropto which it is applied, whereas the effects of a dressing of framyard manure is seen for many years after. Another thing which must not be forgotten when comparing arti- ficial with farmyard manure is the mechanical effects produced by the latter in the soil, artificial having no such effects. By the fermentation of farmyard manure in the soil its texture becomes improved. Carbonic acid, the most powerful disintegrator known, is evolved, and helps to break up the soil and release the stores of food it contains, much more effectively than any process of ploughing and cultiva- tion. TILLAGE OF MANURE. There is, as a rule, a large quantity of undeveloped natural fertilisers in most soils. If nature were not very conser- vative the careless agriculturist would rob the soil of its most valuable consti- [FEBRUARY, 1909, tuents faster than he does, either by carrying plant food off, or allowing it to leak or wash away. It is noticed that organic matter, as soon as it ceases to live, is revolved into its original ele- ments, and that these elemerts in most cases combine with bases—the phos- phoric acid with lime, the potash with silicates, and so on—and when combined, they are often so securely locked up and preserved that this plant food is not available unless the cultivator does something to help along the natural processes. The cultivator has in most cases taken from the land the plant- food which is easily available, has often robbed it of its humus, hence its mois- ture-holding capacity. The crops then suffer from two distinct causes, first a lack of a full supply of available plant tood, and second from lack of moisture, Tillage makes the plant-food more avail- able. To provide the moisture and not a sufficent amount of available plant-food, would be like giving a horse all the water it requires, but not enough paddy and grass. NO ONE CAN FORETELL how much cultivation will be necessary to secure maximum crops. In some soils the plant-food is extremely lazy, in other soils it may be deficient rather than lazy. The soil that contains an abundance of dormant plant-food is more valuable than that which contains asmall amount of available food. In the case of annual crops the reason why soluble plant-food is frequently so beneficial is because the plants when youtg cannot secure from unaided soil sufficient nourishment, and they become dwarfed, and never entirely recover. Ifa sufficient supply of plant food has not been provided for the young plants by tillage, it is always well to add available plant food which may serve as a Starter. A young calf cannot be well nourished on straw. } 2 ir . /34d ,, lo fine bold heavy ..|3}d a 4d leek Dull to fine .. — .,./8d_a 33a Fair to fine ae ..

CARAVONICGA COTTON AND ITS SPONSORS. INTERNATIONAL COTTON COMPANYS OPERATIONS. Ittis avcurious coincidence that ou the heels of Mr, Stewart McCall, who has just reported on the prospects of cotton-growing for Ceylon, should come—from Queensland—the well-known inventor of Caravonica Cotton, Dr. David Thomatis ; but: it is more curious still that they should be meeting at Aden next week and travelling thence to Kast Africa, by Ger- man steamer. It remains to be seen whether Mr. McCall will be persuaded as to the merits of the bigger-yielding species, and get it taken up in Nyasaland, rather than the Egyptian variety which he at present favours. Dr. Thomatis called on us on Jan. 15th on his passage through by the N. L.;‘‘Roon” and surprised us by what he told us of the way the hybrid cotton he has bred has been taken up on the Conti- nent. Himself coming of Scottish and Italian percentage, he appears to have combined the persistence of the one race with the ingenuity of the other; and it has only been the work of about five years to bring to perfection the cotton, which—grown at his plantation at Cairns—has already made his name famous. It has been tried in South India; but—Dr. Thomatis thinke—its failure there must have been due to unseasonable planting or unsuit- able rainfall. lu Queensland, he says, where The: Supplement to the Tropical Agriculturist they have anything from 138 to 200 inches 4 year, the rain falls practically all during the four months January to April, and the crop- ping conditions are excellent. Having made (Jueensland his home, the land of his adoption, and of his unique work, the producer of Cara- vonica wished to open up land on a large scale there; he would have been supported to the tune of several millions sterling, had he been allowed by the Australian Goverument to im- port some thousands of Indian coolies for the purposes of cotton-growing. But Australia— against its own interests, as we hold, but yet in favour of such colonies as Ceylon which feel each strain 1 labour-recruiting competition !— refused to allow black labour in for the enrich- ment of even its most tropical colony, Queens- land. The capital has, therefore, been diverted elsewhere, Caravonica, as produced by Dr. Thomatis, has fetched the highest prices, 1s 2d to 1s 5d per Ib. and over ; but, being so tine, has not found great favour ir. Lancashire, where it is still considered a fancy class of cotton, and too fine for ordi- nary work, Much machinery in Lancashire has been altered to suit Egyptian cotton, which is finer than American; we wonder whether the turn of Caravonica will similarly come later on at the hub of the cotton-spinning world? On the Continent, meanwhile, it has been widely taken up; in France, the silky Caravonica is used for making all the finer classes of cotton goods— while another kind of ‘ woolly’ cotton, which Dr. Thomatis has also bred, is widely used as a substi- tute for wool. Butit is in Germany that the | inventor has been received with open arms ; and at Berlin, are to be found the headquarters of the Syndicate, called the International Cotton ° Company (‘‘ Der Baumer Gesellschaft Caravoni- ca’’) which has been formed in the past year. The Company, comprising several Huropean banks and leading Cotton men on the continent, is designed to control and direct the produc- tion of Caravonica cotton—through recognised and approved landowners and agriculturists. If has a capital of some £6,000,000 to £7,000,000 and willlend money at 3 per cent and provide seed. The only restrictions are that no seed must be sold or disposed of to any one out- side the Company, though as to the disposal of the cotton itself the Company makes ro restriction. It is, however, willing to buy it—or act as selling agents when desired. Asked how the disposal of seed could be so controlled over the wide field of operations proposed, Dr. Thomatis said the Company would be dealing with honest men, to whose interest it would be not to dispose of the seed except as their credi- tors (the Company) required. Dr, Thomatis is Advising Director to the Company and_ while he has left a Manager in charge of the plantations (once his own) in North Queensland, he is now enroute to Dar-es-Salaam, German East Africa, to select land—either already occupied by set- tlers, orto be occupied, to be cultivated with the new product. Already, he says, some 750,000 acres are under preparation in the Soudan, to grow it; while Kastern Cuba is the other (fourth) large centre where its culture will be carried on. The ‘‘ Fram,” the vessel from Norway of Arctic exploring fame, has recently taken and Magazine of the Ceylon Agricultural Society. 6u to 70 Norwegian families to settle in the last- named country on chosen land expressly to grow Caravonica. [The Berlin office telegraphic address, t may be incidentally mentioned, is composed of the first letters of the four offices of the Company: Berlin, Alexandria, Cairns, and Dar-es-Salaam, G.E.A.—Ber-al-ca-dar, if we remember rightly.] Dr. Thomatis tells us he was somewhat disappointed at the result of the experiment in Ceylon—the effort of Mr. J. W. Chas. De Soysa not representing, he thought, what could still be done with season- ‘able planting and the most careful attention. Possibly Ceylon was not the right climate for it, as the fibre produced here showed some degeneration from the parent stock. But for those who are willing to try again, Dr. Thomatis thinks there would be no difti- culty in supplying seed through the Ceylon Agricultural Society to approved growers and lending the money required on the Company’s easy terms. The Agricultural Society would do well to approach the Head Oftice of the Company—‘‘ Der Baumwohlgesellschaft Cara- vonica,” 86 Constanzerstrasse, Berlin W_ (15) —and obtain full particulars at an early date. {t would be interesting if those who are per- suaded by Mr Stewart McCall’s forthcoming Report on the conditions of the North-Central Province, to take up cotton growing, wero at first to grow both the Egyptian species and Caravon- ica hybrid and compare results—with a view to further operations. Caravonica is said to yield one ton to theacre (2,240 lb.), about 90 per cent of pure fibre being obtainable from a properly grown crop, against a minimum ot 300 Lb per acre which Mr McCall thought probable here with Egyptian and 130 lb. per acre actually ob- tained at Maha Illupalama so far. ‘‘ Caravonica fetches over six times the price and gives two or three times the yield,” Dr. Thomatis said, on hearing the Ceylon figures. ORCHELLA WEED. The Imperial Institute, London, reports a shortage of this dye-weed and enquires whether any merchants in the island would be willing to take the necessary steps to resume theex- port of the weed from Ceylon. This Colony was rather noted for its orchella weed at cone time, we believe, and in a work of reference we see that in 1851 in the Great Exhibition some specimens were exhibited from Ceylon whose estimated value was £389 per ton. In the ‘‘nineties’’ we believe the trade in orchella was very brisk. A great dealof it used to be gathered in the Jaffna Peninsula. where it grew on trees, and was sold by the natives to merchants in Colombo for from four cents to six cents. The weed is called in Tamil ‘‘Marappasi.” The market price varies but in 1889 £60 per ton was received for the Ceylon article in London. In view of the interest that is likely to be revived in this commodity by the Imperial Institute’s inquiry we quote from an article |by the late Mr. 187 Henry Meade, written probably about 60 years ago, an interesting reference to orchella weed. Some INTERESTING Facts, We quote the following from the Tropical Agri- culturist, Oct., 1889, as of special interest at this time, in view of the report that there is a shortage of the Weed in the London Market :— At the head of the list of Dye Stuffs stands the “ Roccella Tinctoria ” and ‘* Roccella Fuci- formis,” the Orchella weed of commerce. This article was first exported by myself, in the beginning of 1859 ; it was found growing in great abundance at Calpentyn, and over a range of about fifty miles of the narrow strip of sand, which lies between the Calpentyn lake and the sea. HMnormous filaments of the ‘‘ Tinctoria, ’ some of them as much as eighteen inches in length, by three-quarters of an inch in breadth, were found hanging in clusters on the decayed branches of the oldest mango trees, whilst the mimosas and several varieties of ‘“‘asclepiadece ’’ furnished varieties of the ‘‘ Fuciformis,’ still more valuable, The Palmyra trees and Coconut trees were found to be thickly clothed with the lichen, except in those instances where they had been frequently climbed. There was scarcely a tree or bush that was not covered, more or less, with the Roccella, of the worth of which the people were wholly ignorant. It has now become a regular article of commerce. Except on the tract of seaboard, stretching from Chilaw to Tangalle, the whole line of coast exhibits Roccellas, growing more or Jess luxuriantly, but always confined to a narrow belt of vegetation within the influence of the sea air, On the salt marshes of the western coast, and on the boarders of the lagoons it is invariably found, and there is a large growth on the eastern side of the Peninsula at Trincomalee, and about the leways of Hanbantota. Where the roots are not torn off, it is reproduced yearly. Though every variety of Roccella is well worth gathering, there are some kinds that are much more valu- able than others ; and the following simple test will enable anyone to ascertain the comparative richness of the colouring matter which they con- tain. Fill a bottle half-full of water, put as much of the lichen in, as will leave room to shake the contents of the bottle thoroughly, and add as much spirits of ammonia as will make the liquor unpleasantly pungent, Shake the bottle occasionally during six or seven days, opening it now and then to admit the air, and at the end of that time the water will exhibit arich purple colour, deepening in intensity for about a fortnight when the maceration is com- pleted. A comparison of the result of different experiments will show the volourific value of the various kinds of weed, and the test is one that never fails. If a lichen fails to impart colour to a mixture of ammonia and water, it is not a dye stuff, whatever else it may be good for. The Orchella dye requires no mordant. To fix the colour on cloth it is merely necessary to pour the solution above-described into boiling water, and immerse tha wool or cotton to be dyed in it for half-an-hour. The dye is not a permanent one, but its extreme beauty will always make it acceptable to manufacturers, who use it’ to impart a finish to their goods, 188 MANURE. Any information on this subject should be gladly read by agriculturists, so the following paragraph may strengthen planters in their appreciation of bulky manure versus artificials : Much to the surprise of those connected with the Cleansing Department of Leith, a sudden demand has arisen for the street sweepings, agriculturists now show- ing a preference for this kind of manure. No less than eighty tons of street sweepings are collected in the town per day, and the fact that this is now so easily dis- posed of would seem to suggest that farmers are viewing with less favour artificial manure, the cost of which is of course, so much greater. I donot know whether my persistent writing against artificial manures and in praise of bulk is bearing fruit amongst the farmers near Leith ; but I can see, with pleasure, the good effect produced in my own neighbourhood. Frequently I am told by some neighbour that he has taken my advice and, for several years, has spent nothing on artificials, but plenty on feeding stuffs, so that his cattle manure is far superior to what it used to be, and the crops he is growing have im- proved in alike ratio. Naturally 1 am pleased to know that I have been of good service to my neighbours, and, naturally, the manure merchants don’t like me for having burst up their little game. The street sweepings of Leith, mentioned above, should be very valuable, as I know how much benefited land is by being top- dressed with the scrapings off a turnpike road. CosMOPOLITE. BURYING VS. BURNING PRUNINGS. Lindula, Jan, 14th. Srr,—As regards burying prunings my advice is ‘‘don’t.” My experience of it, and thank goodness a very small one, is thata 19 acres operated on “‘ moreover basic slag” has ever since been a martyr to leaf disease (grey blight). Luckily I read Dr. Watt shortly after the experi- ment; that put me off it for ever. He says, and I believe truly, the roots take up disease from the leaves.—Yours faithfully, E. R. WIGGIN. THe Economic DisPosat or Tra PRuNINGs.— There can be no doubt about Mr E R Wiggin’s opinion on this matter, It is expressed else- where with an emphasis, which to borrow a musical phrase, somewhat suggests the pro- cess of ‘‘ forcing the note.” The tendered advice, judging from Mr Wiggin’s experience, may be very good for estates upcountry ; but we know there are those who will question its value to lowcountry properties. As a matter of fact, we have heard very keen advo- cates of burying prunings admit that on upcountry estates, where the decomposition of prunings is likely to extend over a con- siderable time, there may be a danger of root disease being started. On lowcountry estates, where decomposition is rapid, it is held that no such danger exists; and for every estate upcountry where burying prunings has been a failure, a case in the lowcountry can probably be quoted where the result has been conspic- uously successful, The estate of Mahawale for The Supplement to the Tropical Agricullurist instance is a case in point. That estate was at one time considered a poor one. Prunings have been buried since 1904. Artificial manure is also applied and albizzia leaves buried ; and the following table, showing an annual increase in the crops, indicates that the burying of prunings has had anything but an untoward effect on the tea :— 1904 ... 482 lb. per acre. 1905 ... 552 ,, ‘s 1906 VOBTSICN ws 1907 . 746 ,, a 1908 ne As 8078; td . The cost of production on this estate is 23°38 cents per lb. but that includes the supervision of 650 acres ot rubber. If this were deducted, the cost would approximate 22 cents. ‘¢ Quod cibu est alvis, aliis est atre venenum” appears to be true of estates as of individuals; the question, therefore, seems more or less to resolve itself into this: that what can be practised with safety and much benefit on some estates, may be attended with the most disastrous results if tried on others where different conditions prevail. THE COPRA INDUSTRY. IN SINGAPORE. It has been brought to my notice on one or two occasions recently that the Singapore market price of Copra is nearly always less than that quoted for Ceylon and the Pacific Islands, In order to ascertain’ the reason of this I recently made careful enquiry into the state of the market and the quality of the Copra offered for sale. What surprised me most was the very poor quality of the Copra imported from the surrounding Islands and the Malay States com- pared with that from Java and other Dutch Islands. After examining numerous samples taken from consignments from many different parts I am not surprised that Singapore prices do not compare favourably with those of other markets, ‘There are several causes which account for the inferior quality and price of local copra. The principal cause appears to me to be the absence of some systein of super- vision over the native and Chinese Growers. I believe that in Java and other Dutch Islands the Dutch Government examines all Copra for export and only that which is up to standard quality is allowed to be shipped. This, in a great measure, accounts for the excellence of Dutch Copra. The second cause is that it is a common practice to pick the coconuts before they are quite ripe, thus accounting for the large quantities of thin, soft and decaying Copra on the market. Quantities of good ripe Copra are frequently ruined by mixing it with this half-matured stuff. The third reason is that the Copra is badly dried. That said to be sun-dried is only partially dried and as soon as put in bulk becomes mouldy and _ rots. That said to be kiln-dried is practically roasted. A fourth—and by no means least important— reason is the absence of any form of beneficial cultivation on the estates. In the majority of instances trees are never by any chance manured, nor is any form of beneficial cultivation prac- tised. The result of this neglect is an inferior and Magazine of the Ceylon Agricullural Society. Copra, poor in oil-producing qualities. I am now referring to Malay and Chinese owned estates which comprise practically the whole industry. It is well-known that European owned estates produce Copra of the very highest quality; but, unfortunately for their owners, the poor quality determines the market ear Ceylon Copra obtains a better price, chicfly because the large majority of coconut estates there are owned by Huropeans and under European management and every care is taken to turn out Copra of first quality. The Pacific Islands Copra maintains its advantage in price principally because Messrs Lever Bros. and other well-known soap manufacturers have extensive interests there. They have representatives on the spot who insist on first-class Copra being sup- plied and in return pay the highest price. The difference in price between good and bad Copra in Singapore is about $1 per picul. The present price for first quality is about $7°50. As the price rises, it is customary for many native and Chinese growers to resort to the injurious PRACTICE OF RUSHING QUANTITIES OF UNRIPE, BADLY DRIED COPRA on the market in order to catch the higher rate. This is a practice which cannot be too strongly condemned. The principal sources of supply are Dutch Borneo, the Natunas and Anambas Islands, Johore, the Malay Peninsula, and the Dutch Islands generally. Singapore pro- duces over 3,000 piculs of Copra per month, chiefly from Tanjong Katong and Passir Panjang. This, with the exception of a small quantity from European estates, is badly dried and contains a large percentage of unripe nut. Dutch Copra trom Billeton and Banka is principally kiln- dried and arrives clean, well-dried and of good quality. That from Padang, Sumatra, is in small pieces, well-ripened, dry, dark and oily in appearance and contains more oil than any other Copra imported to Singapore. This is due to careful cultivation and none but well matured nuts being gathered. The Celebes give us a good Copra, well dried from fully matured nuts, yields an excollent oil and shews careful pre- paration. Asahan exports fine large Copra, ripe and fairly well dried both by sun and kiln. Pontianak produces dry Copra of fair quality containing a small percentage of unripe nut. Saigon (Singkawang; Coprais of good quality, dry, and shews careful preparation. ‘l'ernate Islands Copra is very good, generally dry. Kelantan Copra is good but that from Johore, (Batu Pahat) is very wet, unripe and mouldy. Rhio sends good samples of Copra, but occasion- ally the quality canuot be depended on. | have recently seenshipments from Malaccaand Muar which were very bad indeed: in fact, it is said that Copra from these two places is the worst sent in to Singapore. In one store I saw several lots heating s» badly that it was impossible to bear the hand between the sacks. (Quite half was unripe and little or no attempt had been madeatdrying. [am informed on good autho- rity that the quantity of bad Copra from Malacca is steadily increasing. Selangor Copra from native and Chinese sources 18 of fair quality but contains a good percentage of unripe nut, also sand and other impurities, 189 The exports of Copra are to Russia, France, Spain and other continental ports and recently to the United Kingdom. The exports of coco- nut oil from Singapore in 1907 reached 159,801 piculs of which 40,163 piculs were imported chiefly from Pontianak. The imports into and exports from Singapore in each of the 5 years 1903 to 1907, and for 9 months of 1908 are : -- Imports. Exports. Year. Piculs, Value. Piculs.

These facts and the above figures demonstrate the importance of the Copra Industry to the Peninsula and sur- rounding Islands and also shew that there is a renewed interest in not the least important of our agricultural staple industries. Itis hoped that this renewed interest will bring about better cultivation and induce growers to take more pains in the preparation of their produce for market, / T.

AMERICAN COCONUT OIL MARKET. INCRESING USES AND DEMAND. Chicago, Dec. 16, 1908.—The demand for coconut oil has firmed up and prices are higher than they have been for some time. Thisisa condition that was hardly looked for by the trade. Not within many years: has THE OUTTURN OF COPRA the raw material from which the oil is made, been as large as it has within the past year. Every island in the Pacific from which the trade receives copra contributed more thau its usual quota, Importations into this country have been very liberal, though forming a smail part of the total productions. The two mills on the Pacific Coast have been kept in constant operation during the greater part of the present Season, and the production of the domestic oil is reported to have been much heavier than it was last year. And yet, in spite of the larger yield of copra, in spite of the greater production of oil, the demand for the latter is now so keen that makers and importers alike are forced to 190 The Supplement to the advance their prices. ‘This is declared to be due to the larger uses to which the oil is now being placed. The EDIBLE OIL IS BECOMING MORE AND MORE A FACTOR in the trade. The candy manufacturers are using it to a greater extent than ever before, the biscuit manufacturers are finding more use for it every day, and the oil is now being devoted toa great extent to the making of butter, which shows chemical com- binations very similar to those of the ordinary commercial cow butter. Of course, the chief use of the oil as yet is in the manufacture of soaps, where the demand is greater than ever. Russia is declared to be a heavier user of the oil for this purpose ‘than ever before. With all the increase in the supply of copra, the absorption is said to have more than kept pace. California oil is a product which under the present conditions can hardly compete with the regular Ceylon and Cochin oil handled by the importers, except in the territory west of the Missouri River. The great cost of freight keeps the American makers out ofthe Eastern and Middle West markéts, Kansas City being about as far east as the California makers can come. Now and again a carload is sold in Chicago, but this is the exception rather than the rule. The recent appearance of a representative of one of the Western coconut oil manufacturers before the Ways and Means Committee of Con- gress, advocating THE PLACING OF A DUTY ON THIS OIL raises a question as to the advisability of a tariff. The position of the makers of the oil can be well understood, When it is considered that a shipment of oilcan be made from Marseilles to Chicago cheaper than it can from San Fran- cisco, it canbe seen that the chances of the American makers, whose factories are located on the Pacific Coast, to be near the base of supplies competing with the French broker, are very slight. The difference in the freight rate from the Pacific Coast to Chicago, and the rate from New York to Chicago, is about 48c. in favour of New York. Itis urged that a tariff of 3c. per pound on the oil wovld place the oil manufacturer in a position where he would have an even chance with the foreigner. It isa well- understood tact that the operations of the bigger mill of the two on thecoast have been carried on at a loss, simply because the oil could not be sold in the country of its production outside of a limited area—an area where the demand for the oil is not the heaviest. If the theory ofa tariff is to build up infant industries, it is urged that here is an industry in an infantile condition which might be made a big factor in the employ- ment of many men inthe future. Without that tariff, there can be little chance for a broaden: ing of the market, the makers urge. Chicago price for East India Cochin is 7#c., and for Ceylon Cochin, 7ic. spot and Jan-March. California Cochin is quoted at 74c,, and Ceylon at 63c.—New York Oil Reporter, Dec. 21. Tropical Agricultwrist THE U. S. A. SOAP MANUFACTURES IN TARIFF REVISION. OpPosING THE TAX ON Coconut O11 ENTERING THE U.S. A. Washington, Dec. 4.—An important confer- ence of leading representatives of the soap industry was held in this city on Monday of this week for the purpose of arriving at a basis for the representations which the soap trade desires to make to the Ways and Means Com- mittee with respect to the revision of the Dingley tariff act. The coconut oil producers, appeared to regard the revision of the Dingley act as affording an excellent opportunity to secure protection not only for factories operat- ing in the United States, but for those recently established in the Philippine Islands, The re- presentatives of the latter factories were careful, however, to state that their proposition for a relatively high duty on coconut oil when im- ported into the United States from a foreign country was conditioned upon the establishment of free trade between the United States and the archipelago. Itis assumed that m connection with the general revision of the existing tariff law Congress will authorise mutual free trade with the Philippines, except in sugar and to- bacco, upon the importation of which certain restrictions will be imposed, and itis obvious that the duty on foreign coconut oil with free oil from our insular possessions would give a tremendous boom to the Philippine factories established within the past year or two. The soap men have viewed these developments with considerable apprehension, and at their conference in this city they did not hesitate to denounce the efforts to impose duties on the raw materials of the soap industry and to insist that the tax thereon be entirely eliminated. — New York Oil Reporter. A GOCONUT PEST IN COCHIN. A Sprcrant Report. The Cochin Gazette received today contains a Special Report by an officer of the Madras Department of Agriculture on the Pura Lepida found affecting coconut treesin Cochin. The Report after detailing the systematic position, records of occurrence, distribution, life-history, food plants and enemies of the pest, goes on to deal with the nature and extent of its attack on the coconut palms of Cochin. The last section of the Report deals with remedial measures, in which the investigator says:— ‘Considering the height to which the coconut palm grows and the great extent of the foliage to be reached, none but very powerful spraying machines can be of any use. Hence under present conditions, checking the pest with insecticidal sprays is out of the question. The best method, as to checking the increase of the pest, would, on the part of the Jand-owner, be a careful look out for the appearance of the pest and prompt action finding it out. The infested fronds must be cut down and instantly burnt; the cocoon must be carefully looked for on the crown at the base of the leaf stalks and after and Magazine of the Ceylon Agricultural Society. being collected must either be buried deep into the soil and trampled, or summarily consigned to the fire. It was found from enquiry that the post in question was no new thing in the State. Some of the people aftirmed that the same pest had about 10 or 15 years ago appeared on and caused much damage to trees in the narrow strip of land between the sea and the backwaters, to the north of British Cochin, From the Report of the Superintendent of Agriculture, it may be seen that the pest had been observed some 30 years ago in some localities. From this it is evident that the pest is neither a new nor a rare thing in the Cochin State. It seems to be always present in that vast coconut forest, breeding normally in small numbersin some cor- ner or other, and only sporadically increasing so as to become a very serious pestto small areas. It seems ordinarily to be keptincheck by its bracon parasite. he presence of a hyperparasite on the latter is again an indication of the long stan- ding establishment of the pest andits parasite within the Coconut belt. The trees attacked, in general, completely recover, death occurring only in very rare cases. The increase of the pest can, moreover, be easily checked by cutting down affected branches and burning them. Again the pest is one thatis very slow of increaseas may be inferred from the long duration of its pupal period. Under these circumstancés, the nature and habits of the pest do not seem to justify the wholesale panic felt by some of the suffering pro- prietore since it is by no means such a dangerous and invidious foe as the fungus causing the coconut palm disease.”—Jf, Mail, Jan. 6. PESTS IN THE F.M. S. A New ORDINANCE TO PREVENT INTRODUCTION, Nearly all the Colonies especially those of the tropics have now regulations as to the import- ation of plants or seeds from countries in which there is any animal or plant pest affecting these plants, and through which the disease is likely to beintroduced. These regulations are intended of course to protect cultivated plants only, and are usually, but not always,enforced when there is a definite disease affecting an extensive culti- vation in the country of the would be exporter, and the same cultivation without the disease in the country to whichit is intended to export the plant. Thus Jamaica for many years prohi- bited the importation of any living plants of whatever kind from any country which there was cultivated coffee affected with Hemilesa Vastatiz, and thus kept the disease out of the country fora considerable period. There are diseases which no man can possibly prevent the invasion of as the distances which spores of fungi can float on the wind is very great and in countries at all contiguous they can drift across ifthe wind is suitable. The bee hawk moth, the caterpillar of which was so destructive to the coffee some years ago inSelangor, is also a very long flyinginsect. I foundit quite abundant in Christmas island over 200 miles from the nearest land it could have come from. But these are rather exceptional cases and most plant diseases appear to be accidentally imported by man. Inthe interests therefore of 191 the great areas of cultivations of plants now- a-days, it is essential to prevent as much as possible any disease that has unfortunately ap- peared in one country from invading another. Hitherto there has been no ordinance per- mitting the Colony to refuse to allow to be imported diseased plants, and it became clearly desirable that it should have this power. Hence at the suggestion of the Director of Gardens the following Ordinance has been passed :— STRAITS SETTLEMENTS ORDINANCE No. XIII oF 1908. An Ordinance to prevent the introduction into the Colony of pests and insects destructive to trees, plants and crops. Itis hereby enacted by the Governor of the Straits Settlements with the advice and consent of the Legislative Council thereof as follows :— 1. This Ordinance may be cited as ‘The Destructive Pests Ordinance 1908.” 2. The Governorin Council may from time to time make such orders as may to the Governor in Council ap- pear expedient for preventing the introduction into the Colony of any insect, fungus or other pest destructive to agricultural or horticultural crops or to trees or plants and for preventing the spreading in the Colony of any such insect, fungus or other pest. 3. Any such order may prohibit orregulate the landing inithe Colony of any tree or plant, or the leaves, branches, stems, roots, seeds or fruit of any tree or plant, or any vegetable substance or other article the landing whereof may appear to the Governor in Oouncil to be likely to in- troduce such insect, fungus or other pest and may direct or authorise the treatment or destruction of any such article, if landed. Any such order may also direct or authorise the treatment, removal or destruction of any crop, tree plant, or substance on which the insect, fungus or other pest in any stage ofits existence is found, or by means of which it may appear to the Governor in Council to be likely to spread, and the entering on any lands for the purpose of suchtreatment, removal or destruction, or for the purpose of any examination or inquiry authorised by the order or for any other purpose of the order. 4. The Governor in Council may from time to time make orders for the payment of compensation in respect of any crop, tree, plant or other substance destrcyed under the provisions of this Ordinance. 5.

Hundreds of cocoa trees in Jamaica, we read, are dying from a root trouble which is said to be caused by the attacks of asmall white grub, This grub is of the same nature, if not identical, with the larvae of the orange weevil, the “ Fiddler ” bug. Small doses of lime spread over the soil in the radius of the trees is found to do good, but is not entirely effectual if the trees are badly at- tacked. The best way that has so far been found to get rid of the grubs, so as to kill them wholesale, is by the use of Bi-sulphide of Carbon. For 10 years back it has been em- ployed to kill weevils in grain and the ants which make nests at the roots of fruit trees. Tt is a volatile gas, heavier than air, so that when applied on the top of a barrel of corn or on the top of an ant hill, or around the roots of trees, it sinks and kills all animal life below, within limits of course. To apply this to a cocoa tree, or to every cocoa tree ina plantation, is abig 192 operation; and a doubtful one, because a few drops of it are not guaranteed to kill the grubs through the whole soil radius of a cocoa tree, and too much of it may dainage the trees. It is, however, recommended to be tried on trees that are thought to be attacked by beginning a yard out from the trees and at intervals round each tree, ramming the fork in the soil, then dropping a few drops of the Bi-sulphide in the hole made by the prongs of the fork, drawing earth over the holes at once. THE NEW RAPID SYSTEM OF TAPPING RUBBER. We understand that the report on the new system of extracting latex, referred to the Messrs. Lee Hedges & Co.’s circular of Novem- ber, (see page 591 of December T. A.) which has been prepared after witnessing a demons- tration shortly before Christmas, has reached Mesers. Lee Hedges & Co. from Joseph Fraser and Clements. It is not above-named for a copy of for publication. Weunderstand, however, that —though, of course, it is too soon yet to obtain evidence as to how often the same surface may be tapped by this system in a year, without injury to the tree, or as to the effect on the tree after some years of numbers of tappings, the advan- tages claimed have been established, namely : 1) cost of plant not above usual current methods; 2) simplicity ; 3) reduced cost of production ; 4) little—or no apparent—damage to the trees ; 5) labour-saving ; and 6) quicker and possibly increased returns, We believe the system can be much varied or modified at will and is not expected to be more fatal to the tree than other methods (possibly the reverse) if it be not employed entirely in order to extract the maximum of latex in the minimum of time. Jan. 7th. Dar Sir,—In connection with the new tap- ping system of Messrs. Lee Hedges & Co., on which Messrs. Joseph Fraser and Cloments’ report is eagerly awaited, it is of interest to recall! that Mr. Petch, the Government Myco- logist, has spoken against the use of the pricker on several occasions, and, I understand, he has not yet seen any reason to alter his opinion. . I hear, too, that the new method of tapping rubber, which is now being boomed, involves the use of the pricker. If it does, the inventor must wait until he can demonstrate what is the condition of the tree two years ‘after tapping, before he can_ speak of the success of his method. But Dr. Willis has _ given his approval of the system, though I cannot discover that he has considered _the pathological side—the structure and reactions of a Hevea tree. I am strongly of opinion that the use of the pricker causes the formation of lumps on the renewed surface and makes it untappable. You have only to look at the trees Mr. Herbert Wright tapped at Henarat- goda two years ago.—I am, yours faithfully, EXPERIENTIA DOCET. The Supplement to the Tropical Agriculturist THE TREATMENT OF ACID SOILS FOR RUBBER AND OTHER CULTIVATIONS. A series of experiments have been begun by the Department of Agriculture on some low lying flat land which has abnormally acid soil, rendering it unfavourable for the rapid growth of root growth of rubber or other cultivated plants. The presence of a too large proportion of acid in peaty soils is due to the existence of a large proportion of humic acid which is a brown or black substance produced by decay- ing vegetable matter. This decomposition is greatly facilitated by heat, air, and moisture and by the presence of putrefying nitroge- nous matter. The conditions in many clear- ings in Malaya are therefore specially suited to the formation of an excess of humic acid which exists in many places to such an ex- tent that the roots of young rubber are not able to grow and the plants grow without vigour and in some cases succumb. Such soils are physically and in other respects, most suitable for healthy and rapid growth of rubber and when the amount of acid has been reduced they often produce exceptionally fine rubber. The question of the naturalisation of such soils in the shortest time is of great im- portance. The only method used at present is to allow the sun free access to the soil and by this means and plentiful drainage to gradually eliminate a proportion of the acid. This is however a lengthy and not always successful method and a much quicker plan is to add such proportion of basic substance such as lime - as is needed to neutralise the acid in the coil. A very large supply of natural phosphate is being extracted from Christmas Island and can be delivered comparatively cheaply at 8. 8. and F. M.S. ports. This raw phosphate not converted into the superphosphate will be tried on acid soils. The advantage in using this manure is that the raw[pbosphate i.¢., phosphatic rocks exactly as they are obtained in nature is cheaper than the manufactured superphosphate and the acid in the soil of the superacid lands will con- vert the phosphate into superphosphate and by so doing the soil will more rapidly lose its acid and become neutralised and the available plant food in the soil greatly increased. The costs of such an application of raw phosphate will be determined by experimenting with different quantities per acre to discover the smallest amount necessary to render the soil favourable to root growth of rubber. In certain cases the lack of vigour in_ the growth of young rubber on acid soils has been attributed to dampness of soil, fungi or other diseases of the roots and it will be well if in cases where there is reason to suspect that the chemical condition of the soil is the cause of the lack of progress of rubber plants a portion of the field be treated to reduce the acidity. On some of the super acid soils a litmus Pape pressed against a handful of the damp soil gives in a short space of time, some few minutes, a marked acid reaction i.e. is changed to a pink colour. This may be used as a rough test of the relative amount of acidity in the soil. J.

Sumarra Russer.—The manager estimates that the revenue from coffee during the current year will be more than sufficient to meet the es- tate expenditure. A census of the rubber trees taken by the manager is reported by him to show a total at May 31, 1908, of 173,079. Since the 23 198 opened land was surveyed in November, 1907, 66 additional acres have been opensd and planted, making the total area opened and planted at May 31 last 1,811 acres. It is in- tended to bring the amount up to 2,100 acres during the current financial year, The growth of both the rubber and the coffee 1s satisfactory, RUBBER PLANTING IN THE WORLD. PrERAK.—We have just received a letter dated 3rd Jan., 1909, from Taiping, Perak, in which the writer states :—The growth of Rubber is very rapid. Applications for large areas of land for Rubber are still coming in to Government. A Mr. Ross, who has already 800 acres planted, is applying for another 600.—Cor. Borneo.-—As a proof how eminently suitable British North Borneo is for the cultivation of Para rubber, it is stated that sixty trees, about 64 years old, in the Government Experimental Gardens at Tenom, on the railway, produced last year 107 lb. of rubber, or an average of about 13 lb. per tree.—H & C Mail, Jan. 8, In JAvA AND SumatTRA,—Rubber Cultivation is expected to show considerable development in thefuture. At the present time it is estimated that in the Netherlands East Indies over 87,500 acres are devoted to rubber, of which 57,000 acres are situated in Java, Many of theold plantations consist of Ficus elastica, but latterly the Para tree has been extensively planted.—H ¢ C Mail, Jan. 8. Souru AcHEEN.--Inthe Tamiang district, South Acheen, rubber cultivation is going ahead so far as labour difticulties will allow. The planters freely avail themselves of Achineselabourers, They are found to be far preferable to Malays, who will not work on the fields if they can help it, so long as fishing gives them a means of livelihood. The Governor of Acheen, who lately visited the dis- trict, was much struck by seeing how Achinese could be utilised for estate labour, and promised to do his best to open up Tamiang for planters. —Straits Limes, Jan, 23, A Brkp’s Eye ViEw oF RUBBER PLANTING, — Anyone travelling on the branch ofthe FM SR which connects Kuala Lumpur with Port Swettenham has been able during the last few years to observe from his seat in the railway carriage the different stages through which a rubber estate passes from the clearing of the virgin jungle to the tapping of the established trees. In addition, says a correspondent, the traveller can now see in practice several exam- ples of the clean weeding and weed exterminator theories, some estates with nothing but bare earth under the trees, others with crotalaria and others with passion flower.—Matau Mail, Jan. 18, RuBBER IN TRINIDAD.—A gentleman who was recently in Trinidad and proposesto return with a view to settlement in the colony, writes from Mexico, where he was staying on a rubber estate of 400,000 trees as follows to a Trinidad paper : —‘‘]T thought it might interest you to know that the ten-years-old Rubber Trees (Castilloa elastica) here are not larger if so Jarge as those of four years old of which I took photographs 194 at New Lands and they are certainly not as heaithy locking. This 1s the home of the Castilloa, and it grows wild in the woods but from what I have seen ofit inCeylon, the Malay States, etc., I should decidedly say that it does best in Trinidad, if New Lands Rubber be taken as a sample.” Stack Estate MANAGEMENT IN JAVA.—On an estate in Asahan, Delhi, which is managed by a company domiciled in Germany, serious com- plications have arisen, The outlay on the spot has, of late increased so alarmingly that the directors sent out two delegates to inquire what had brought on this untoward result. Commenting on this incident, the Deli Courant calls attention to the lack of control over certain estate managers who are left free to charge the property with outlay which should be placed to their personal account. This is done mostly froia carelessness rather than out of set purpose. So loose is the system that the auditing of estate books is seldom given thought, though stricter control would check mismanage- ment, lavish outlay, and uncalled-for expendi- ture.—Straits Times, Jan. 20. QUEENSLAND,—Though still in the experimen- tal stage, is making progress. Six varieties of rubber-producing plants now under cultivation are admittedly likely to be of use to the country, and are growing well. As yet only four have attain- ed maturity. The Ceara rubber has only been spasmodically tapped. While under ten years of age or so, experiments have been unsatis- factory; but as they increase in years, the flow of latex seems to increase, and to flow for a longer period after the bark is cut. On the Ram- bong trees experiments have indicated that, with cultivation, a size may be attained rend- ering it both possible and worth while to com- mence tapping operations at nine years or so of age, and possibly earlier. The large trees growing in Queensland are some 16 years of age, and will give as much as 5 1b. of dry rub- ber per annum. Tapping operations are sys- tematically carried out on the small plantations of Para rubber trees, which are now eight years old, in the Government Tropical Nursery in Kamerunga.—L & C Express, Jan. |. Sr. Lucia.—Rubber plants (Castilloa, Hevea and Funtamia) have been raised in considerable number at St. Lucia Botanic Station, and some estates have made experimental plantings. In 1906-7, the number of rubber plants distributed from the station was 18,167, of which, however, only some 7,0C0 were planted in theisland. In 1907-8, the total number sent out fell to 7,438, of which only about 2,000 were distributed locally, and the Curator states that at present there is practically no demand for rubber plants at St. Lucia. The plantings already made will continue to be kept under observation and experiment, and a good stock of plants still exists at the Station. A consignment of ten packages of seeds of ‘© Hevea brasiliensis,” comprising a total of 2,059, was received from Ceylon in the past year. The seeds were packed in charcoal dust, and were altogether about two months in transit, Of the seeds received, 947, or about 46 per cent., germinated, Observations on the condition of The Supplement to the Tropical Agriculturist the packages on arrival indicate that the best results were obtained from the seeds in those tins in which, on arrival, the charcoal dust was dry. The Curator, in his latest Annual Report, expresses the opinion that Castilloa rubber trees will thrive exceedingly well in St. Lucia, if due consideration is given to the selection of suitable soiland locality.—W.I.

S. NiegeRra.—Rubber is an important item in the export trade of Southern Nigeria, and it is consequently interesting to note that the planting of rubber trees by the natives has been steadily encouraged by the Forestry Department, and that in some districts the plants are doing very well, and give good promise for the future. According to Mr. Birtwistle, the Government Commercial Agent, it is now generally realised that not until the rubber trees are owned by individuals, who will see that they are duly protected, can this industry in Nigeria be looked upon as one ofa permanently-progressive nature. Thousands of trees in the forests, which are practically a ‘‘no man’s land,” are destroyed each year by over- tapping, and, although every effort is made by the Forestry Department to regulate the gather- ing and to prevent indiscriminate bleeding, the task in so large a country and amidst dense forestsis an extremely difficult one. Incidentally it may be observed that a decade ago the ex- ports of rubber from one province alone averaged over five million pounds weight per annum.— Haé C Mail, Jan. 1. Sincaporr Ruspper Factory.—The Neder- landsche Gutta-Percha Maatschappij (Nether- lands Gutta-Percha Company) report tor the business year 1907 a deficit of 101,661°154 florins, which, added to the former deficit, brought the total to 249,358°574 florins. The deficit for 1907 includes 13,001°323 florins written off for de- preciation, and Magazine of the Ceylon Agricultural Society. The directors state that the decline in selling prices of gutta-percha caused a loss as to the product in stock at the beginning of the year. There waslarge expenditure in starting the rub- ber goods factory, at Passir Panjang. The hope is entertained that better conditions will now prevail. Additional capital has been provided, and profits are looked for from the Singapore plant, as well as from the leaf gutta business, which is the primary object of the company. The idea is being considered of manufacturing goods from the company’s own raw product, The gutta-percha plantations were extended to 285 bouws[402°82 acres], and 15 bouws have been planted in Hevea rubber—about 20,000 trees— which number this year is to be increased to 75,000. The greater part of the gutta-percha has been interplanted with cinchona (quinine), and 5,500 florins, net, was derived during the year from the sale of bark. The plantations are in south-west Java, and the administration in Holland.—Sétraits Times, Jan. 11. THE PINEAPPLE INDUSTRY. THe PingaPrLe Inpustry—is the subject of an informing article reproduced on this page. Who is there that grows pines on a large scale in Ceylon?—and what has he to tell us about them ? We protest against Ceylon pines being called insipid, even if they have not the flavour of those fine specimens which cost half- a-crown or more at home. That there is a huge demand for first-class pineapples in India, and almost a total absence of supply, will not be readily denied. To be sure, pineapples are grown more or less exten- sively in almost every part of India; but, in the vast majority of cases, not the slightest attempt has been made to improve the quality of the fruit in any way and the actual result is that the pineapples generally offered for sale in most of the bazaars of India are not worth eating, and would not be used except as cattle fodder in countries growing good quality pines. It is not that the pineapple is new to India; asa matter of fact, it has been grown ir this country for several hundred years, and in small tracts on the Malabar Coast, in parts of Northern Bengal and in places of Assam it has been brought to a certain state of perfection. But the demand for Indian-grown pineapples with any semblance of flavour 1s so greatly in excess of the supply that unripe and often INSIPID PINEAPPLES FROM THE STRAITS SETILE- MENTS, CEYLON AND MAURITIUS find a ready sale at 2to 4 annas each. On the other hand. we have heard of a small garden in Northern Bengal growing luscious pineapples which has no difficulty in selling them at 8 annas apiece. The same sort otf thing is probably done in other parts of the country on a small scale, but the broad factis, as Sir George Watt tersely puts it in his revised edition of the Com- mercial Products of India, just issued : ‘‘ Little orno effort has been put forth either to im- rove the quality or to develop on a commercial hana the industry of pineapple growing, which, it would appear, might be originated with ad- vantage to India and profit to those concerned.” 195 It may be interesting at this stage to make a rapid survey of what has been done in other countries in establishing the pineapple industry on a commercial basis. Fifty years ago the pine- apple was unknown in Florida: today one may stand on any elevated position on the East Coast of Florida and look out for miles over solid fields of pineapples, no other cultivated crop being in sight. The red Spanish pineapple comprises about 98 per cent. of the total plan- tings, Abbaschi, Smooth Cayenne and Porto Rico making up the remainder. The crop an- nually produced is considerable, being more than half-a-million crates, each crate Tholdiad from 18 to 48 pineapples according to size. In pe ilalp the preserving and tinving of pine- apples is a large and growing industry. In 1906 we tind that 707,495 cases of preserved pines were shipped from that port, while the export for 1907, the latest figures available, com: prised 845,976 cases. There is avery large de- mand for preserved pineapples in the United Kingdom and on the Continent and this demand Singapore largely supplies, Florida chiefly con- fines herself to the export ofripe fruit. Buta more striking example of what can be done in establishing a pineapple industry on a sound ba- sis in a short space of time is furnished by the Hawaiian Islands, which promise to outstrip both Florida and the Straits Settlements at an early date. Here the industry was only started about three years ago; but, under the gui- dance of an enthusiast, has made such gi- gantic progress that the output of preserved pineapples in 1910 is estimated at 24 million cans. In 1907 the output was 190,000 cases, each containing 24 cans, but this is less than half the estimated output for last year. Already Bonolulu claims to be in_ pos- session of the largest canning factory in the world. This factory is to be capable of handling 20 solid car-loads, or 300 tons of fruit, in 10 hours, or at the rate of half-a-ton a minute, When running to capacity it isexpected that the factory will turn out between five and six thou- sand cases of canned pines every day. And what can be done on acommercialscale in Honolulu, Florida and the Straits Settlements can pro- bably be also done in a greater or lesser measure in [udia, which boasts of every kind of climate, from the mildest to the most severe. A point in favour of the pineapple industry ig that it is a comparatively simple one. The pines may be grown upon land that will produce ordi- nary vegetables, provided such land is well drained even in times of excessive rain. To obtain the very best results, however, a friable soil and a porous subsoil are essential. Such land stands drought well, as capillary attraction is good under such conditions. In Florida pine- apples are planted 18 to 24 inches apart, but in the Bahama Islands as many as 20,000 pines are planted on a single acre, each plant pro- ducing one pineapple. This number of pine- apples at 8,4, 2 or even 1 anna each would leave a handsome margin of profit per acre. But it is not only from the pineapples that tho profit ismade: there are by-products. Pineapple fibre fetches about £30 per ton in tbe London market ; and, according to Sir George Watt, there is a considerable demand for it in part of 196 Northern Bengal and the Deccan. In the Hono- lulu preserving factory large quantities of juice are obtained by crushing the course and parings by running them through rollers of the sugar mill type. The refuse may be used as fuel for the furnaces, while the juice may be converted into pineapple brandy, vinegar syrup and extracts; and it has been recently suggested that possibly pineapple sugar might be made by boiling the juicein avacuum to the crystal- lising point, Such isarapid glance at the pineapple in- dustry as practised in the countries named ; and it may possibly be worth the while of some one to consider whether it could not be successfully established in one or more parts of India. We may add that the imports of fresh fruit into India last year were valued at R2,85,381, and, although the imports of pineapples are not separately recorded in the Customs returns, the figures go to show that there is a substantial demand for fresh fruit which, under present conditions, this country is unable to supply.— Indian Trade Journal, Jan. 21. PINEAPPLE GROWING IN CEYLON. We asked recently whether there was any- one in Ceylon who grew really first-class pine- apples. We have since had the opportunity of seeing and tasting a very fine large pine, prown on Mr. Jacob de Mel’s well-known estate, Lilukewella, eight miles from Kurune- gala, on the Kandy road. We are told that very much larger ones are frequently grown on the same estate, though this was well over 12 inches long and 18 inches in circumference. If pineapples of such size, quality and richness of flavour can be produced in Ceylon, sureby it would be worthwhile for the industry to be taken up here on a large scale by some enter- prising agriculturist. Mr. de Mel’s are of the kind known as Kew pines, and are far more worth growing than the ordinary common little country pineapple, such as is commonly sold in the markets in Colombo and Kandy. RECORD WEIGHT OF PINEAPPLE. Jan. 28th, Dear Sir,—The ordinary weight of a good Kew pine (Smooth Cayenne)—as grown here at the Government Stock Gardens—is 15 or 16 lb. I find ina Royal Botanic Garden’s circular (series 1, No. 15) the statement that the fruits of this variety sometimes weigh over 20 lb., but no definite maximum figure isgiven. Last year Mr WA de Silva, Veterinary Surgeon, Columbo Municipality, sent me a fruit, grown in his pro. perty at Waga, which turned the scale at 21 1b _ A few days ago, however, Mr M Suppra- maniam, Broker, of Colombo, brought me one which, on being carefully weighed, was found to be 24lbs 5% oz. Has this record been beaten P—Yours truly, C, DRIEBERG, The Supplement to the Tropical Agriculturist THE STRAITS COPRA INDUSTRY. Why not D.C. Nut? Viewing the increase that. Singapore has established in its trade in copra, which is yearly expanding, a correspondent thinks it is sur- prising that local merchants do not import machinery for desiccating coconuts. This has been found to be a large and profitable indus- try in Ceylon, and might conceivably do as well in the Straits.—L & C Express, jan. 1. MR. J. B. CARRUTHERS’ NEW APPOINTMENT. Mr. J. B. Carruthers, formerly Mycologist to the Ceylon Government and at present Director of Agriculture and Government Botanist in the F.M.S., has, accepted a postin Trinidad. Mr. Carruthers has done excellent work both in Ceylon and the F.M.S. and tropical agriculturists in the East generally will regret.that his services are being transferred to the other side of the globe. What the precise post Mr. Car- ruthers has accepted is we are not told; but it is thought at the Secretariat, and we think it very likely, that he has been selected to succeed Mr. J H Hart, v.1.s., as Superintendent of the Royal Botanic Gardens at Port of Spain, Trinidad, who after 32 years of valuable work to Tropical Agriculture recently retired. A new Department of Agriculture has recently been formed in Trinidad and in the latest papers to hand we note that subject to the approval ~ of the Secretary of State for the Colonies, His Excellency the Acting Governor has appointed Professor P. Carmody, F.1.c., F.¢.s., to be Director. This appointment (which Professor Carmody will hold in addition to his office as Government Analyst and Professor of Chem- istry) will date from November Ist last. The following previously separate Departments have been amalgamated to constitute the new Department of Agriculture: (1) the Govern- ment Laboratory; (2) the Botanic Gardens (including the Experimental Station, Trinidad ; Rever estate, Trinidad; and the Botanic Station, Tobago); (3) the Government Stock Farms at Trinidad and Tobago, and (4) St. Augustine estate. Jan. 27th. Duar Sir,—That is interesting news you published stating that Mr Carruthers is going to Trinidad to succeed Mr Hart, as Direc- tor of the Botanic Gardens, etc. I1t seems almost a pity that Mr Carruthers has been moved so soon from the Malay States, where he is in the early stages of a lot of experimental work, which he has now no chance of bringing toa conclusion, and of which there will likely be no results as his successor will, in’ all probability, not continue on the same lines, As he stated at the Ceylon Rubber Exhibition, he hasa number of rubber experiments in hand and these will takesome yearsto bring to any result; his departure will be a loss to Malaya planters. In the field of literature, too, .Mr Carruthers has been active, and has shared the and Magazine of the Ceylon Agricultural Society. 197 Editorship of the “Straits Agricultural Bulle- tin,” which is a very useful planters’ periodical. Butin Trinidad he will have the editorship of another Agricultural Bulletin which, under Mr Hart, has done very well; and Mr Hart filled each quarterly number almost’ entirely by him- self ; the volumes ofthe Bulletin are a monu- ment of useful work done by him. Mr Carruthers has good knowledge of rubber, cacao and coconuts as cultivated in Ceylon and Malaya which will be very useful in his new career, for these products are being extensively done in Trinidad. Rubber there is coming to the fore. Cacao is a very paying product though some Ceylon methods might well be adopted, and coconuts are a product which is likely to be extended. Asa botanist Mr Carruthers will have great scope; and his home in Trinidad will be among most pleasant surroundings. He is certain of the good wishes of many Ceylon friends including numerous planters,— Yours faithfully, ADMIRER. FAILURE AND FORTUNE IN NYASALAND. “H. B.” responds to the criticisms in these columns (October, 1908) that he had not told us yet of any fortunes made in Nyasaland, while writ- ing ofits advantages. From what he says, tobacco would seem to be the most paying crop ; while cotton has not been a success, We wonder if the latter has been wrongly planted ? How- ‘ever, it will not be long now before Mr. Stewart McUall, the new Director of Agricul- ture, who believes it is the product for the country, arrives on the spot to show the plan- ters how it should be grown and harvested. Mlanje, December, 1909. In my hints to new-comers and investors, who might be inclined to try their fortune in Nyasa- jand, appearing in your issue of October last, there was no reference to past failures, but simply facts as they exist at present; but as ‘“Sceptical” refers to the NYASALAND COFFEE CO.’s FAILURE in 1901 without even paying a dividend to the shareholders, I feel bound to reply—as it is very probable ‘‘Sceptical ” was a shareholder, and I myself was their V. A. When the Nyasaland Co. was formed and during the first few years of its existence, coffee was, to all appearance, to be the future industry of the country; and from crops that had been se- cured from various estates, there was no getting over the fact that money invested in this pro- duct was to all appearance safe, and bound te yield good interest in the course of time, Jt is very doubtful if one man could be found in or out of B.C, A., who, in view of the circumstances surrounding the industry at the time referred to, was then bold enough to give an adverse epinion to the general one: that B. C. A. was the home of the coffee tree, and that there was a fortune in it. As time went on, however, we began to make dis- coveries that there were NATURAL ENEMIES of the coffee tree to contend with, of no trifling nature. The larger the area that was opened up, the more and more numerous those enemies be- came, until they proved too much for the coffee enterprise, and the result was wholesale abandonment all over the country. Not only the Nyasaland Co., but many others had to close down after years of hard honest work, which did credit to those who struggled to make coffee pay. A great many FINE BRICK BUNGALOWS and godowns standing in the bush in the different districts throughout the country bear evidence of the confidence in the coffee enterprise, Nya- saland planters were not satisfied, like Ceylon pioneers, with a wattle and daub house to begin with and wait to see whether the estate was going to pay or not, for many of the houses cost £500 to £600 and more—bhefore even a berry of crop was harvested. To sum up the failure of coffee in this country. If a coffee clearing is opened and comes into bearing during years that are ‘unfavourable’ for the deve- lopment of insect pest, especially thrips (which is mostly ruled by the early or late bush fires and monsoon rains), a heavy crop and, perhaps, two, can be secured ; but on the other hand, if the season is favourable for breeding those in- sects, the leaves and bark of the young wood and berries are so damaged by their sinking and puncturing the sap-cells, that one may as well cut down the plants and let a sucker grow up, for they are damaged for life, This ACCOUNTS FOR MANY COFFEE CLEARINGS NEVER ‘ GIVING A CROP in Nyasaland and even after cutting down the trees the suckers have been also damaged in the same way. COTTON, Cotton, for some who have been years in this coun- try, has been a complete failure ; and for others, it has given a very paying crop, indeed, but the risks, of course, are a great deal too serious for small capitalists. Was it not Mr J W Home who had to abandon the cotton industry in the bed of the Muturajawela tank, Ceylon (after spending some £7,000), owing to insect pests, in the ’six- ties or seventies? ‘‘Sceptical” wants to hear of PLANTERS WHO ARE GETTING BIG RETURNS IN THIS COUNTRY at present. He might as well ask a man for his Bank balance. The planters that are left here are men of small means, who have managed to tide over the coffee crisis, with few excep- tions; but Ican mention one not very far away from here, who sold about 7 tons of tobacco at 7d per lb., which cost very little to grow and put on the market. I know another, who got 11d per Ib. for 12 tons, aud yet another, who sold 20 tons of cotton at 74d perlb. 7 tons of tobacco fetched 1s 13d per lb. not very long ago. Chil- lies, I have just got the account sales for — tons, sold at 56s per cwt. I could tell you of many who have not only made a living here, but have been able to clear out of the country with a few thousands ; but not fortunes, that people are usually in such a hurry to secure. How many of the Ceylon planters made’ fortunes out of Coffee, or even Tea? The writer thought that 10 years was enough to make a fortune in Ceylon and 5 years in Nyasaland; but, alas! —the schemes of mice and men! H. B, 198 THE LONDON RUBBER MARKET. SOME HINTS FROM THE BROKER TO THE PLANTER. We have now received, and in most cases place before our readers, the annual reports on tha rub- ber market during 1908 issued by the principal firms of rubber brokersin London. ‘They con- tain, as far as we can discern, nothing that can be regarded as discouraging to the producer of plantation rubber in the East. In fact in every case confidence in the great promise of the industry is unmistakeably indicated ; and, in not a few, invaluable hints are given to planters regarding the form in which the raw product is most acceptable to the manufacturers. The interest of the trade in the plantation article is broadening in proportion to the increase of supplies ; and there is every reason to justify the conclusion that, when still greater quanti- ties are put on the market, a correspondingly ready demand will be experienced for it. ‘The production and imports into London of plan- tation rubber during 1908 are given by Messrs. Lewis & Peat as 2,100 tons against 1,250 tons in the preceding year. At the present time no department of the trade has refrained from handling plantation rubber,and the above-named firm assures us *‘ with confidence that now, practically all manufacturers, large and small, use plantation rubber and are likely to do so more and more.” The large rubber firms are making arrangements to deal with larger quantities when the supplies increase as they must do enormously during the next few years. This is a gratifying and tangible sign of practical interest in cultivated rubber, which ought to stimulate planters to produce only the best. It is very important at this stage that the good impression made by the plan- tation product should be maintained, and by the adoption of the hints given by the London brokers the quality improved and made still more acceptable. The more important of the recom mendations may be emphasized here. Messrs. Figgis & Co. state that the manufacturers showed a decided preference tor plantation rubber in the form of Sheet, Biscuits and Crépe, and with regard to the latter, planters are warned that ‘‘it should not be drawn out too thin or have visible air or steam bubbles in it.” There seems to be a very ready demand for pale pure Crepe, provided the preparation has been thorough. Lhe firm quoted strongly advises planters to wash and clean the rubber thoroughly and to prepare as large a proportion as possible of good colour and not to send to London many qualities or small lots. Block, they say, ‘‘has not beer in favour generally; and unless clean resilient hard quality can be sent, it may be better to ship as Crépe or sheet. Pack it in good dry condition (excess of resin much objected to.) Into strong cases of 1 ewt. to 2 cwt. each. No paper, fuller’s earth, &c., to be used. Keeping different qualities and colour separate; where practicable, keep im- mature separate ; to send separately dirty bark “pieces, and to wash out all the bark in Crépe, Block and Sheet. All fine qualities should be loose Crépe, Sheet or Biscuit—not run to a mass,” The Supplement to the Tropical Agriculturist These instructions are clear and definite and to comply with them ought not to seriously tax the resource of the planter. Messrs. Gow Wilson and Stanton point out that while some samples of plantation rubber have been pronounced to be equal in all respects to fine Para, in certain cases weakness and variation of quality are still complained of, and they say “it is very evident that every effort must be made to raise the standard quality to a higher level.” Messrs. Lewis and Peat point out that in the case of ‘‘sheets’” a regular standard quality has been established, making business easier both for sellers and buyers. This firm also strongly recommends planters to prepare their scrap in Crepe form, taking care not to roll too thin, which makes it weak and brittle. Scrap Crepe, they say, ought to be hard. strong and gristly. Pre- pared thus, scrap realises higher prices. They also point out that very fine pale worms com- mand a very high price; but that as the quan- tities increase, the quality—as far as colour is concerned—is not as good. There appears to be apprehension that with quantity will come less regard for quality on the part of the producer. It is in the Ceylon planter’s interest that he should strive to allay this fear. As to the market itself it is very satisfactory to find the statistical position so sound and to know that this is not due to any marked falling off in supplies but to the steady improvement in the trade absorbing the surplus stocks. The world’s supply in 1908 was about 65,000 tons, against 69,000 tons in 1907 and 65,000 tons in 1906. The consumption. in 1908 is estimated at about 67,500 tons; - and on this point Messrs. Lewis and Peat, give the cheering assurance that although “Production must increase enormously during the next few years, even now the trade is ready to cope with it whatever its dimensions.” The past year therefore, with its unexampled fluctuations, was not entirely without points of advantage for plantation rubber. The recovery made by the market in the second half of the year was remarkable and he would indeed be deemed ‘‘a cheery optimist” whoa year ago ventured to predict that 1908 would close as favourably asit did. At the present moment the market is quite as satisfactory as any reasonable person could hope for and better than most of us anticipated it would be a year ago. We then had low pricesand large stocks: we now havelow stocks and,comparatively speaking, high prices. The future not being born, we are not going to christen it. But without laying ourselves open to the charge of making unduly optimistic prognostications, we may say that if the expert opinion of these London Brokers is to count for anything, the outlook is dis- tinctly promising. We have heard it stated locally that one Ceylon estate has sold its crop forward at 5s per Ib. If this is correct, one buyer at any rate anticipates a high level of prices to be maintained during 1909. Whether prices tise or fall, however, planters cannot do better than carry out to the best of their ability the useful instructions conveyed to them by the Brokers in London. By so doing they will secure better prices for themselves and, what is still more important, help to establish for all time the reputation of Ceylon Plantation rubber, and Magazine of the Ceylon Agricultural Society. MESSRS. FIGGIS & CO.’S REPORT. Fine Brazit, AMAzonas, BoLiviaANn, PERUVIAN AND (WiLD) Meptiom. 1908 will be remembered as a year of record variations in values and enormously increased price at the close, compared with the beginning of the year: also the constant large demand for fine Para, which al! countries have wanted in Jarger proportion than formerly. Asa result the advance today compared to this date last year is ls 8d per lb. on fine Para, but only 6d to 1s on Negrohead and 10d on Caucho Ball. For the reasons stated in our last annual, prices declined last January and February, several American factories continued closed ; consequently too much Rubber was lefton the English market. On 2lst February we had the lowest prices of the year, Hard Fine Para being sold at 2s 9d, scrappy 2s. A recovery soon ensued, and as detailed beiow, prices advanced 1s per lb. With eager American Regine and cornering of large bear operators, we had a further great advance in November, prices then being about double those of February 21st. Mediums were only saleable at very low prices till November, and the disastrous results to importers aud holders, seriously restricted imports, resulting in stocks being abnormally smallnow. English consumption of Rubber has been very large, that of France and Germany good, Russia only moderate, and America much less till quite recently. We think invisible stocks must be large in America, owing to her very free buying this last three months. The European stocks are exceedingly small. The world’s supply of about 65,000 tons has been all consumed. In 1907 we had 69,000 tons, 1906 65,000 tons, and we begin this year with very small stocks of all Rubber (especially mediums). ‘‘Slab Rubber” was scarce and sold well, ‘* Ball” plentiful (and of good quality) and very ready sale. ‘‘ Tails” only saleable at low prices, The supply of mediums was much smaller. West Coast African declined. _ W.C.A.—Only 14,000 tons against 17,000 tons in 1907, 17,200 tons in 1906 and 17,500 tons in 1905. VISIBLE SUPPLY lst JANUARY, 1909.

The enormous variations and great advance in prices since early October (fully detailed over leaf), have resulted in very high ‘‘average price” for Plantation during recent inontiis but, as we formerly predicted, the difference in value corn- pared with fine Para Brazil Rubber, lessens with the larger supply of Plantation. Manufacturers have shewn a decided prefer- ence for Sheet, Biscuit and Crepe; the latter should not be drawn out too thin or have visible air or steam bubbles in it. Some lots of strong thick Crépe sold very well. We think it has been profitable to planters to wash’and clean the rubber thoroughly, and to prepare as large a proportion as possible of gcod colour—also not to send many qualities or very small lots. Block has not been in favour gene- rally, and unless clean resilient hard quality can be sent, it may be better to ship as Crépe or sheet. Pack it in good dry condition (excess of resin much objected to.) Into strong cases of 1 cwt. to 2 cwt. each. No paper, fuller’s earth, &c., to be used. Keeping different qualities and colours sepa- rate, where practicable keep immature separate; to send separately dirty barky pieces, and to wash out all the bark in Crépe, Block and Sheet. All fine qualities should be loose Crépe, Sheet or Biscuit—not run to a mass. Our LONDON CHARGES are very small. Brokerage 4 per cent., AJl Samples are paid for, and_the only deduction is—Discount 2} per cent. Draft (on all Rubber) 4 per cent. Smoked rubber appears to have greater re- siliency and to be more suitable for many pur- poses than unsmoked. ‘* Smoking” prevents the ‘“‘ proteins ” in rubber from decomposition, and generally from ‘‘ tackiness.’’ All fine rubber from Para is smoked. During last January and February we had de- cline in markets (from the values of Ist January, viz., fine Para 3s. 5d., fine Plantation 3s. 11d_), owing to the withdrawal from purchasing Rub- ber by America, and the continued closing there. of many factories.

The rapid fluctuations and extraordinary rise in values appear hardly due to natural or normal causes, but the world’s demand has been more than equal to the reduced supply, and at some periods our stocks have been re- markably small, especially of fine Para. Total stocks now are smaller than for many years. Notwithstanding the serious losses in Brazil, the supply from the Amazonas has increased, but there has beena large reduction of Mani- coba, Mangabeira and Pernambuco. Brazil exported 40,000 tons.

Tue Years Saues,—The quantity of Plan- tation Rubber brought to auctionin London during 1908 was 24,647 packages, amounting to 1,2954, tons, compared with 15,380 packages, weighing S14 tons during the previous year. The auction average price for 1908 of all grades was 4s/13d per lb. MARKET Conpirions.—The period under re- view has been ono of marked changes. The industry at the beginning of the year was still suffering from the set-back in prices which took place during the latter part of 1907; both stocks and visible supplies greatly exceeded require- ments, and there was little inclination on the part of buyers to operate with any freedom, During the summer, however, a gradual im- provement was steadily taking place, and while in February the price of Fine Hard Para had receded to 2/9 (the lowest quotation for over sixteen years), by the beginning of August it stood at over 4/ per Ib,, and in the middle of November reached 5/43, which was the highest price recorded for more than two years. The statistical position is now ona sounder basis than it has been for some considerable time past, owing not to any marked falling off in supplies, but tothe steady and continual im- provement intrade, which has resulted in the absorption of surplus stocks, more especially in America where for some months past stocks in warehouse have been negligible. THE POSITION OF THE PLANTATION RUBBER InpustRY—has become more important, owing to the increase in production, and in many in- stances a marked improvement in preparation of the Rubber has been readily appreciated by buyers. Itisa gratifying fact that some sam- ples of Plantation Rubber have been pronounced to be equal in all respects to Fine Para, but on the other hand, complaints as to weakness-and variation in quality are still too numerous, and it is evident that every effort must be made to raise the standard quality to a higher level. VARIETIES ON THE Marxet.--As the quantity of Plantation Rubber produced has been in- creasing, various new forms and methods of pre- paration have been tried and a large number of different varieties have consequently been put on the market. This has led to some confusion, and it is advisable that the number of different forms and grades should be reduced as far as possible consistent with proper sorting. Biscuits, Sheet, Crepe and Scrap continue to meet with steady support, but a noticeable feature has been the increase in the proportion of Crepe, owing to more estates having started the use of machinery. Though certain buyers continue to take Sheets and Biscuits in pre- ference to Crepe, the demand for the latter has _ been well maintained, and very satisfactory prices have been paid for the more carefully prepared samples, 202 . The enquiry for very pale pure Rubber which has been in evidence for some time past con- tinues, and premiums of up to about 4d. per lb. over ordinary Fine quality Plantation Rubber have been readily paid for increasing quantities. Up till now the supplies of such Rubber have only been small, but the uses for it may still expand considerably, and there should be room for a largely increased supply in the future. For all kinds of Crepe, provided preparation has been thorough, there is a good sale, and prices even for the lower qualities have com- pared very favourably with those for other grades, Propuctrion oF PLantatTion RuBBER.—From the table below it will be seen that the total production of Ceylon and Malaya Rubber for 1908 was about 750 tons in excess of that of the previous year, The bulk of this increase has been derived from Malaya, Ceylon only show- ing a small expansion. Owing to the rather large area of land which was put under cul- tivation in the East during 1902-1903, we antici- pate that a relatively greater increase in sup- plies will be seen in 1909, while in a few years time the production of Plantation Rubber is likely to form an appreciable proportion of the world’s supply. xports of Plantation from Malaya and Ceylon: The Supplement to the in Tons.

Tur Para Crop.—Contrary to expectations, the shipments of Amazon Rubber from Para so far this season (i.¢., since July Jst, 1908) have exceeded those for the same period of the pre- vious season. This is to some extent accounted for by the supplies having come down from the forests more rapidly than usual, and it does not follow that the total crop will be larger than last season’s, whilst on the other hand, stocks throughout the world have been materi- ally reduced.

The closing sale of the year passed off witha fairly good demand for all descriptions except Sheets and Biscuits for which, in some instances, competition was rather slow. The market has Tropical Agriculturist been quiet since the holidays, but prices have been rather firmer, and quotations at today’s auction marked an irregular advance of from 1d toin some cases 2d per lb on last sale rates. A large parcel of Lanadron Block weighing about 6 tons was partly sold at from 5/10 to 5/104 per lb., this being the highest price of the sale.

FRoM CEYLON, THE STRAITS AND MALAY STATES FoR 1908. 6, Mincing Lane, London, Jan. 1. The satisfactory feature of the past year is the marked increase in the production and imports of Plantation Rubber, viz., 2,100 tons against 1,250 tons in 1907, and the very large increase in the number of buyers and consumers, who now use Plantation sorts, keenly competing for them at the London auctions and by private treaty. Instead of increased supplies adversely affecting the market, consumers, who have taken to using it, have been more and more interested in it, from the fact that they are able now to depend upon getting what they want regularly and in increasing quantities, which at first with only small supplies was a difliculty. The larger quantities catalogued at the fortnightly sales which averaged something like 100 tons per month have been readily taken. The private - business between the sales has also developed considerably, and we now have a regular and open market for all qualities. We may say with confidence that now, practically all manu- facturers, large and smai!, use Plantation Rub- ber and are likely to do so more and more. In consequence of the growing importance of Plan- tation Rubber, the largest and most important firms in the trade being best able to judge of its preat future, have made and are makin their arrangements to handle and deal with it in greatly increased supplies. Production must increase enormously during the next few years but even now the = : TRADE IS READY TO COPE WITH IT whatever its dimensions. Throughout the year fluctuations in the price of rubber have been very great, and during the American depression and cessation of buying, heavy stocks of all grades including medium and wild rubber ac- cumulated enormously; at one time the stock of mediums alone in Europe amounted to some 10 or 12,000 tons and was for some time practically unsaleable. With the fine para crop coming in and being pressed for gale, the price dropped to 2/9 perlb., the lowest price touched for 10 or 12 years—and as there were scarcely any American orders, European buyers had to take the bulk of the pee This decline in fine para brought down the values of plantation and of all grades—but with a good European demand throughout and a revival of American orders—quite A SENSATIONAL REACTION set in about the middle of the year, and _ prices rapidly advanced pence per |b. almost without a break until November, when fine para and Magazine uf the Ceylon Agricultural Society. touched 5/5 per Ib. and plantation 6/, With the greatly enhanced values of fine para and the en- ormously increased consumption shown by the hoavy deliveries to all parts, consumers turned their attention to medium grades, and the whole of the enormous accumulated stocks disappeared and went into consumption. These facts speak for themselves and show the very healthy state of the rubber trade generally, notwithstanding the constant complaints of bad trade and siack business. Nine months ago we had enormous stocks and low prices; today we haveexceedingly small stocks and excellent prices aud a good de- mand, One result of the very heavy decline in the values early in the year of medium rades and wild rubbers (other than para) Baa unquestionably been to enormously decrease the production and collection of a great many sorts, and hence our stocks have not been re- plenished by them, and it is very doubtful if they will be, if supplies of Plantation are avail- able and suftticient to meet the present largo and ever increasing demand. It is impossible to give any forecast as to prices in the future, but we are of opinion that fluctuations will not be heavy for some time to come, and we look for a continued good demand both for Fine Para and Plantation, a demand sufticient to take and con- sume at satisfactory prices all that the Amazon and Plantations are likely to send us at present. BISCUITS only come in small quantities now, and no doubt this form of preparation will give way to sheets or Crépe which are far easier to manufacture and handle on the Estates. Tho very finest and palest Warriapola biscuits have always sold at fancy prices for special purposes. We have also had good lots from Sorana, Tallagalla, Dens- worth, Doranakande, Syston, Arapolakande and Langsland. SHEETS have come in increasing quantities and a regular standard quality has been established, making business easier both for sellers and buyers, Consumers can now depend upon their purchases and get larger and increasing quantities with but a comparatively small variation in quality and loss in weight. In this grade, colour has made but little difference in the price, buyers rather going by the strength and condition, The best known marks came from Vallambrosa and Highlands and Lowlands Estates, and their shipments have been most regular in quality and of considerable size. Amongst the best stan- dards attained we may also mention Perhentian Tinggi, Bukit Rajah, Jugraand Deviturai. The Penang Sugar Estates have also sent some re- matkably good lots, CREPE, The bulk of the Plantation Crop now comes in this form, and wethink it can be taken as the most satisfactory preparation, Now that the quality and colour is more even and the parcels larger, buyers can repeat their orders and be snre of what they are buying, and an order for five or ten tons can now be executed for a single grade with comparative ease, The quality shipped during the year has beon excellent and the colour has much improved, Tho very fine 203 pale, in some instances almost white, has realised extremely high prices, and there isa large and increasing demand for this quality for special uses. The medium and mottled is always readily saleable. Asto the good dark grades, there are many new buyers constantly enquring, and these qualities more than any other are being used instead of the better wild rubbers, Among the many fine marks that call for special men- tion the following have been specially notice- able : Jebong Crépe, which is almost white, but no longer stands alone, as several other éstates are now producirg quality and colour equally good. Rosehaugh, fine thick Crépe is most popular and one of the best preparations we get. Damansara, Matang, Malacca, Sungei Kapar, Pataling, Linsum, Linggi, Tarentang and Ather- ton are all coming to the front both in the quan- tity and quality of their shipments. Biock. Inthismode of preparation Lanadron Estate still leads, and the shipments have greatly im- proved during the year, the colour being much paler than it was in 1907. Weare glad to notice some nice samples from other estates quite as good in quality, but only in very small lots as yet. Very high prices have been paid, and there are now iarge and regular buyers of fine clean palish. Woks, Very fine pale still commands a very high price but we regret to see that as the quantities increase the quality as far as colour is concerned is not as good; only a small proportion turns out almost white as wanted. Gikiyanakande estate still sends the bulk of this grade, but several other éstates, including Talduwa, have shipped some very fine though small lots, SCRAP —has sold extremely well throughout the year, both in ordinary crinkly scrap form and in brown Crépe. In Crépe form scrap cer- tainly realises a better price; we would strongly recommend planters to prepare it in this way, taking care not to roll too thin which makes it weak and brittle. Scrap Crépe should be hard, strong and eristly, CASTILLOA, Only small shipments from: plantations ave coming as yet, but the sheets from Amban- ganga estate in Ceylon show what can be done, and the rubber from this tree properly pre- pared is nearly oqual in quality to ordinary ’ara sheets and biscuits. Nothing of any note has come from Java and Sumatra so far, and we have only received small lots from the West Indies. The improvement in preparation of small lots from Tobago is most gratifying, RAMBONG (Ficus Elastica)—is nowa most popular grade and has realised splendid prices throughout the year. It is most liked in Crépe form. Some very fine lots recently realised up to 4s 84d per Ib.

PRODUCTION AND EXPORT OF JAVA TEA is undoubtedly on the increase and Java must be reckoned with for the future as an important factor in the world’s supply. The figures we publish elsewhere, show an increase during 1908 of 74 million lb, over the crop of 1907—a 25 per cent. increase! The monthly crop returns have shown a steady increase, which indicates that the advance will be permanent. Nor has the production of Java yet reached its full capacity; A number of estates will only return larger yields with increasing age. Java's tea shipments to England from ist January to 3lst December, 1908 are 12,629,513 lb. against 9,167,312 lb, for the corresponding period of 1907. To. other countries they have been 36,579,536 lb. against 29,288,402 |b. Holland takes 44 million half- kilos more than in 1906, England about 1 million and Russia nearly half-a-million more than in 1907.

This is an extraordinary advance to be made in one year (a 25 per cent increase), especially when it is considered that last year exports were only 26,624,000 half kilos—which relatively small figures should not allow for the large differences - that are possible in the Calcutta exports of some 220,000,000 English pounds or the 180,000,000 pounds from Colombo, Crops have shown steady increase during each month of the year, which is a sure sign that the increase will bea permanent one and that the increased exports are not due to better con- ditions either climatic or local, but to the natu- ral increase from new areas of tea and froma large number of estates which are still coming to their full producing figures with increased age. There seems to be an idea that the Java figures are never made up with perfect accuracy, but the above figures must be taken as being as nearly correct and official as is possible under the present conditions of shipment and custom house returns.

RUBBER-TANNED LEATHER. Paragraphs have appeared recently in the press, from which it will have been gathered that the satisfactory tanning of leather by means of rubber, which has for many years been re- garded as a practical impossibility, has at length been successfully achieved, and will shortly be undertaken on a commercial basis, It is possible the new invention may have, at a later date, some effect upon the raw rubber market ; that being so, planters will naturally wish to know what tanned rubber leather really is, what are its uses and its claims, We are now in the position of being able to afford full details to our readers. The invention, we understand, consists of a process for permeating hides and skins with pure rubber—the result being the substance known as Rubber-Tanned Leather and alleged to possess qualities vastly superior to those of the ordinary bark-tanned leather. Increased life, resiliency, durability, toughness, pliability, softness and water-resisting qualities are claimed to be imparted in the rubber-tanning process, giving a commercial value to the new product far beyond that of any leather at pre- sent known to the market. In the preparation of ordinary bark-tanned leather, the cells of the hide or skin are filled with chemicals, oils and other substances that add considerably to its weight; while, as is well-known, the harmful effects produced far out-weigh any advantages claimed for the process, a rigidity being given to the leather which only remains so long as itis kept dry and inno sense does it become waterproof. In rubber-tanued leather it is ex- plained, the effect produced is almost entirely the reverse, the principle involved being to effectually cleanse the pores of the skin and to extract therefrom all toreign and superfluous fatty matter so that the cells may become avail- able for the absorption of the rubber, The result is the production of a material which is practi- cally waterproof, and which, while claimed to be incomparably more durable than the ordinary commercial leather, is at the same time sott and pliable, qualities which remain some of its distinguishing features even after immersion for lengthened periods in water, and render it avail- able for the manufacture of many articles for which ordinary leather is wholly unsuitable or unsatisfactory. We have seen the reports of many eminent authorities on the utility of the new process, so that the statement of the manu- facturers may be accepted when they declare : — “Leather so treated has been abundantly tested and proved and is suitable for the manu- facture of many articles cf domestic and com- mercial use, including boots of all classes, and particularly Army boots; mining, sluicing and seamen’s boots, where water resistance and soft- ness are essential ; the leather cover for spindles in cotton manufacture; pump valves; washers ; seat rings; covers for footballs, punching balls, tennis balls and others ; harness including Army harness ; saddlery ; belting and lacing for machi- nery : portmanteaux ; solid leather trunks; gig aprons ; leggings ; bags ; soles for use in shoeing horses to protect the frog and for minimising the jar on hard roads and streets; fire hose ; bicycle, motor and Automobile tyres, in seamless and 205 jointless bands, practically unpuncturable, motor strips on the tyres carrying the studs ; &e., &c., and in fact for every article to which leather is applied. In all the articles mentioned, tough- ness and durability, softness and water-resisting qualities are essential, andareattained by rubber tanning. The leather can be dyed to any of the colours that are most used. Weight, so detrimental to the essentials of the products, is avoided, whilst a much greater superficial area, weight for weight—a most important consider ation for buyers in bulk—is obtained, rubber- tauned leather in most cases giving almost double area, pound for pound, as compared with ordinary bark-tanned leather, whilst its dura- bility is enormously increased.” A considerable quantity of raw rubber will, we suppose, be required for the tanning process, Any extra demand for rubber which this may create will, however, we fear, be more than counteracted by the fact that if the new sub- stance fulfils all the claims made for it, articles manufactured from it will supplant many at pre- sent made almost entirely from rubber. The owners of the new process claim great saving in cost by the use of rubber-tanned leather, Rubber tanning, they say, though a little more costly than chroming, is less so than bark-tanning while the rubber-tanned product is greatly superior to both. An important factor in the case of rubber-tanned leather, as compared with bark-tanned leather, is the very short period of time required to produce the former, the result being that there is no locking up for lengthy periods, as in the case of bark-tanned leather, of large amounts of capital represented by stocks in process; while bark-tanning requires anything from 5 to 12 months, the rubber-tanning process occupies at the outside from 5 to 7 weeks only. A large saving in interest on capital is thus effected, while a much superior article, it is claimed, is at the same time produced, GANGARUWA RUBBER EXPERIMENT. With regard to the rubber experiments at Gangaruwa, all the Hevea and Castilloa trees have been planted fifteen by fifteen. The former were measured when 34 years old and the girth averaged about 10 inches. The total number of Hevea trees in the station is 1,305 which in a short time will be bringing in a substantial revenue. There is a plot of 130 Castilloa trees on level ground, six years old and the average girth here is 18} inches. The gradual deterioration in the Castilloa trees planted on the slopes as they go up was re- marked upon, and this is illustrated by the table, given below, supplied to our contem- porary by Mr Lock, No. 1 row being the bottom one, and No. 7 the topmost row. The effect is seen in the number of trees as well as inthe girth. They are all six years old: and above them 1s pure jungle :— , Row.

In our iesue of Nov. 5th (p. 117) we stated that it might interest those concerned to know that a London firm was prepared to pay as much as 12s per lb for dried sheep gut, by which is meant the long intestine of the sheep, cleaned, split, and dried on frames, The labour in con- nection with this industry, we said, was believed to be insignificant ; and we added that, as the product required was probably often wasted in this country, the matter seemed to be worthy of attention, particularly so as the price offered seemed to be quite liberal. This paragraph attracted considerable attention in India and Burma, as well as in some Native States. The ‘fact seems to be that hitherto, in many parts of India, sheep gut has been wasted simply because no market was known to exist for it, and appar- ently no particular efforts were made to dis- cover one. As an instance of this, it may be here recorded, on the authority of Mr. R Burn, IL.C.S., District Officer of Gonda, who has written to us on the subject, that at the time the para- graph appeared in the ‘‘ Indian Trade Journal” sheep gut was selling in his district at from 2 pice ($d) to 1 anna 3 pies (17d) per seer of 2°06 Ib. There is reason to believe a similar state of affairs exietsin very many other districts in India, and more particularly perhaps in Burma. The numerous letters we have received on this subject show, we think, that there are in India both readiness and ability to engage in this particular industry ; bat it is evident that the persons interested in the matter have no adequate knowledge as to how the gut should be handled and _ prepared in order to suit the requirements of European markets. This difficulty we shall now endea- vour to remove ; and, what is perhaps more im- portant, expand the scope of the industry by the inclusion of cattle gut, cattle tail hair, and lamb gut. Cattle gut iscomposed (a) of a long curly gut measuring about 30 yards; (db) a straight gut measuring 10 to 12 yards ; (c) abung measuring from 1 to 14 yards, and (d) a throat of weasand of about 1 yard. As regards (a), this should be cleaned and scraped soon after the animal is slaughtered. Itis then biown, or filled with air, either by a _ pipe-stem blower, or a steam blower, the ends of the gut, of course, being tied to keep the air in. Next it is placed over rope lines to dry in the open. The drying process is completed quickly inIndia. The gut is then deflated by pricking the tied ends witha pin, and is placed in a suitablechamber or box where a vessel con- taining afair quantity of powdered sulphur is kept burning for at least 12 hours. This treat- ment renders the gut immune against moths, etc. Itis then made up into hanks of 20 yards, in one or two pieces; or in balls of 200 yards, and is then packed in pressed bales containing 10,000 yards which is equivalent to 500 hanks or 50 balls. The canvas cover should be lined with strong tar-coated packing paper. We can furnish the address of a London firm which is prepared to take 50 pressed bales per month and pay as much as £12 per bale according to colour, width, length, strength, etc. The narrow- The Supplement to the Tropical griculturist er this gut is, the more value it has. As to (), this should be scraped and cleaned as in the case of (a), but should not be blown or dried. On the contrary, it should be thoroughly salted, made up into hanks of 16 yards and packed in tierces of about 200 hanks with a sufticient amount of salt or pickle to act as a preservative, The market value is from 1s, to 1s. 1d. per hank according to colour, width, strength, flaying, length, etc., but in this case the wider the gut the more value it has. The bungs (c) are scraped and salted, as in the previous case, and made into bundles of 10 pieces and shipped in tierces con— taining an unlimited number. The value varies from 12s, to 15s. per hundred pieces. The wea- sand (d) is thoroughly cleaned, blown and dried as in the case of (a), and is then packed in bales of 50 bundles, each containing 25 pieces. The value varies from about 8s. to 10s. per 100 pieces. Now as to sheep gut. By this is meant the loug cucly gut measuring about 30 yards. If fairly wide, say about #-inch or above, it should be scraped, cleaned and salted and then made into bundles of 100 yards, composed of lon strands well sprinkled with salt and pickle an placed in air-tight tierces of about 100 bundles. The value of this article varies from 1s. 9d. to 28, 6d. per bundle. The wider the gut, the higher the price. [f, however, the gut is only narrow, it should be treated as lamb gut, which, after being cleaned and slit openthroughout its entire eri is placed on wooden frames and dried in the open air. Itis then packed in hanks of about 2 lb. . and putin tin-lined cases of 100 bundles with a thorough sprinkling of naphthaline balls to pre- serveit against vermin, In this case the value varies from 7s. to 12s. per lb. according to colour, length and strength. In the matter of sheep and lamb gut the London firm we have referred to is prepared to purchase all the goods of this class that may be offered ; but dealers on the look out for top prices should bear in mind that special care must be taken when cleaning the gut not to cut holes in the skin, or to affect its strength by over-scraping. By cattle tail hair is meant the hair clipped off the end of the tail, washed, thoroughly dried and packed, preferably in a hydraulic press, into bales about 3cwt. The market value of this is about Is. per lb. according to length, colour and condition. A light colour is preferred. With these particulars before them, we trust that those interested in this special trade will be able to supply the London market with exactly the class of goods that is required. —Indian Trade Journal, Jan, 14 A SIMPLE MOSQUITO TRAP. ees Mr. Lefroy of the Indian Entomological De- partment has devised a simple and cheap mos- quito trap, which is said to have been found highly effective. A small box, 12 by 9 inches, fitted with a hinged lid, is provided with a small opening over which moves a sliding cover. The box is lined with dark ereeu baize and has a tin floor, The trap is placed in a shady and Magazine of the Ceylon Agricultural Society. corner of the room, and the mosquitoes on en- tering the house in the morning seclude them- selves inthe box to escape the sunlight. When duly settled the lid is shut and about a tea- spoonful of benzine injected into the box. We learn that in the course of a month, no less than 2,300 mosquitoes succumbed to the benzine. We expect to see the trap go with a boom.— Indian Planters’ Gazette, Jan. 9. SOAP AND COCONUT OIL. In a letter to the London Z'imes of Jan. 5th, John Knight (Limited) of Royal Primrose Soap Works, gives the following information :— The price of cottonseed oil in January last year was £22 7s 61 per ton at Hull; it has fluctuated shghtly throughout the year, and on December 8lst the price was £23 per ton—the average pricefor the year being £22 10s 3d per ton, as against an average price of £26 per ton for 1907. Palm kernel oil, which at the begin- ning of 1908 was worth about £26 10s per ton, fluctuated considerably during the year until December 3lst, when it rose to about £27 10s per ton. Coconut oil, which at the beginning of 1908 was worth about £28 10s per ton, has likewise fluctuated during the year, until on Dec. 31st, it was worth about £30 10s per ton. Coconut oil, with a poor Ceylon crop of nuts, may go high still. COIR YARN, FIBRE &c. In their annual report quoted in the London Tumes, 15th January, Messrs. Bastone and Firminger say:—Palmyra Fibre has taken an irregular course during 1908, and closing prices mark a reduction of £4 per ton com- pared with end of 1907. At the drop the mar. ket is quietly steady. Stock in London public warehouses shows some increase, viz., 483 tons, as compared with 324 tons a yearago.

A New FErti.isEr. The Dhaincha or sesbania aculeala, a new fertilising plant, was planted at the Government Stock Gardens a few weeks ago and has sprouted up splendidly, The roots of these plants become full of well-developed nodules which when squeezed throw ovt a fluid which is © really protoplasmic and consist of innumer- able bacteria, As a green manure for rice fields this plant is said to be the best, and its intro- duction locally should be attended with splendid results, The mango grafts in the Gardens are also doing splendidly. The rubber, now going on to four years, is doing fairly well, the growth being slow, due to the sandy soil. Mr W Malegoda, the successful candidate in the recent examination, is attached to the Gardens to be trained. CEYLON CITRCNELLA AND LEMON GRASS OIL. INTERESTING REFERENCES IN Messrs ScHIMMEL & Co,’s Semi-Annuat Report. We have received the semi-annual report of Messrs, Schimmel & Co, of Miltitz, (near Leipzig), London and New York covering the period from May to October 1908. It is an elaborate volume and as usual contains much of interest to merchants and planters en- gaged in the preparation and export of Citronella, Lemongrass and other essential oils. In the introduction reference is made to ‘‘the general depression which since the date of our last report has made itself felt more and more on all the World’s markets and has not passed over our branch without leaving its im- print behind. Hand in hand with the rapid fall in the bank rates which occurred on every side, and which proved sufficiently clearly a relaxation of the spirit of enterprise in commerce, came a gradual decline in the values of most materials; and although the turnover during the period covered by the present report shows quantitatively only an immaterial falling-off as compared with that of the previous year, it is very probable that the financial results, in view of the depressed prices which had almost everywhere to be reckoned with, may here and there to a notinconsiderable extent, fall short of those obtained in 1907.” A speedy revival in trade is, however, predicted, and among the most promising signs is reckoned the gradual ‘‘healthy re-awakening of commerce and _in- dustry in the United States.” In the section of the report, ‘‘Commercial notes and scientific information on essential oils,” a good deal ofspace is devoted to Ceylon Citronella Oil; but before referring to these paragraphs we may quote the following re- ference to the general state of the market :— “Business in this important article can only be characterised as extremely quiet and lifeless ; the sales were small, and (as far as old stocks are concerned) were throughout at aloss, Under these circumstances it is not surprising that, as already predicted in our 208 April report, the prices show no fluctuations worth mentioning. The present quotations are just about the same as six months ago, viz., 11 d. cif,, and there do not appear to be at this mo- ment any grounds from which a serious harden- ing ot the prices for forward delivery could be deduced.” Referring to the exports from Ceylon, a table is given showing a con- siderable increase, on the 1907 figures and on this the report states: ‘‘ Although there is no question of an increased export as com- pared with the previous year, which might de- press the quotations, we have yet to reckon with the comparatively small amount of interest dis- played in this article by the wholesale soap in- dustry, especially in the United Kingdom, which will also during the next few months scarcely lead to any better position of the citronella market.” Then follows a curious reference to adulteration of Ceylon Citronella Oil by arrack as follows :—‘‘ We may mention here, for curio- sity’s sake, that the London Custom house re- cently seized and rejected a rather large parcel, because the oil was adulterated with alcohol. The examination showed about 8°/. alcohol ! We may add in explanation that Ceylon produces yearly large quantities of very cheap arrack, and that it was here probably a question of this adulterant. In view of the easiness with which even smal! admixtures of alcohol can be detected in essential oils, the export firms in Galle will probably have no difficulty in pre- venting the native traders who are respon- sible for this, from continuing this practice.” It may not be generally known, that in Germany citronella oil has recently been ad- mitted asa denaturing agent, and the decree of the Prussian Treasury to this effect is quoted verbatim. The step we note has taken on the recommendation of the Association of Soap Manufacturers of Berlin. Until further notice the decree permits the denaturing of fatty oils with Ceylon citronella oil in the quantity 200 grams to 100 kilos of the goods to be denatured. Reference is also made to the discussion at the February meeting of the Agricultural Society of Ceylon on ‘‘Schimmel’s Test.” We quote fer the benefit of those interested the folllowing :— According to Kelway Bamber this test is in- sufficient for judging the oils, and should be amended. Bamber also hopes to be able to find a satisfactory solution of the question, C P Hayley and others, however, lay stress on the fact that the Chamber of Commerce at Galle has unanimously declared that the test satisfies all practical requirements, and that in view of the energy displayed by the buyers, coarse adulteration is at present only rarely met with, Moreover, the consumers are sgatis- fied with the oil now exported. If absolutely pure oils were wanted, it would only be neces- sary to offer higher prices, corresponding to the higher cost of production. These last remarks can hardly be considered satisfactory. In our opinion it would be more correct if everyone endeavoured to place only pure oils on the market, and for this reason one must welcome Bamber’s efforts and give them every possible support. 1tis to be hoped that they will also have the desired effect. Our The Supplement to the Tropical Agriculturist own experience is that the quality of the Ceylon citronella oils has not yet improved as much as might be desired, According to The Chemist and Druggist A W Winter is reported to have stated in Ceylon that neither pure Mahapengiri oil, nor a mix- ‘ture of the latter with Lenabatu oil will pass Schimmel’s test ; but thisis clearly due to a misunderstanding, as the Mahapengiri oil (Java citronella oil) originating from Java, which is the only one to be considered for commercial purposes, readily and completely dissolves in 80 per cent. alcohol, and it would be very strange indeed if the same species of grass yielded in Ceylon a so ditHcultly soluble oil, that it could not even pass Schimmel’s test In the meantime the above statement has been corrected by Samaraweera of Weligama, but notwithstanding this we have taken steps to ob- tain from Winter an authentic Mahapengiri oil distilled by himself, in order to enable us to clear up this question. With regard to Lemongrass Oil Messrs Schim- mel & Co. state that since their last report in April no change worth mentioning has come in the market quotations; the price fell to about 12d to 2d per ounce. The quantities shipped from Cochin China from Ist Juiy, 1907, to 30th June, L908, were about 6,082 cases against 6,239 cases in the same period 1906-7 and 2,259 cases in the same period 1905-6. The future prospects are not, however, gloomy. The report states :— It is not impossible that with an im- provement in trade generally, the price of lemongrass oil will move upwards, for the con- sumption of this oil is on the increase, and has on the whole been able to keep pace with the supplies, in spite of the depression of the last six months. For this reason the visible stocks have remained comparatively small. The large imports from the West Indies which about a year ago were accumulating in London, and which helped to bring about the sudden drop from about 9d in 1905-6 to 2d in 1908, are said to be now for the greater part cleared, and will probably not be repeated so quickly, as the pro- ducers, at the present depressed quotations, can no longer make both ends meet in this trade.

The Cultivation of Passiflora Foe- tida and Micania Scandens. (Circulars and Agricultural Journal of the HK. B. G., Peradeniya, Vol. IV., No. 16. We take it that agriculture may be defined, for practical purposes, as the art of making a profit by the cultivation of land, and that it is the proper object of the agriculturist to obtain the largest possible permanent profit off a given area of ground. In other words, agri- culture is the art of making land as valu- able as possible in respect of the crops which it iscapable of growing. Itis not the planter’s function to concern himself with the beauty of the landscape either by respecting the natural vegetation or by neglecting to tap natural sources of water power ; for example: as in other forms of business, soin agriculture, the question to be decided in the case of any given proposal is, will it pay ? Just as much asin any other agricul- tural operation, the question of weeding, or of weeding in a particular way, must be decided from this point of view. The question before us then is, does clean weeding pay? And we think the answer is obvious that this depends upon the circumstances of the particular case. We are told on all hands that clean weed- ing is cheap weeding, and many people seem to think that the whole philosophy of weeding is summed up in this phrase. But we are not prepared to agree that even this idea might not be better ex- pressed. Weare not surethat another expression is not preferable—if you go in for clean weeding at all, do it thoroughly . If it is decided inany particular case that clean weeding is the best policy, then the more thoroughly it is carried out the cheaper it will be in the long run. Let us trace the origin of the idea of clean weeding. It is clearly derived from the methods of temperate agri- culture, and is particularly applicable to the case of annual crops. Where any kind of an annual cropis grown it un- questionably pays to keep theland clean, If weeds are allowed to seed or spread in any quantity, trouble rapidly multiplies itself. We might almost say that agri- culture in the strictest sense, that is to say field cultivation, consists in the first instance in the extermination of weeds. We think it may be taken as generally agreed that, in the case of short-lived crops, weeding cannot be carried out too thoroughly. When one comes to consider the question of crops which are to occupy the ground permanently, or for a con- siderable number of years, the question of what will pay best is not so immedi ately obvious. We require to proceed somewhat cautiously when we find that men of considerable experience hold 210 apparently diametrically opposite views with regard to the question of clean weeding as applied to the ease of per- manent tropical crops. Let us go back for a moment to home experience. We find that fruit trees at home are grown in one of two ways. Orchards are either laid down in grass, or they are combined with the cultiva- tion of vegetables. Where fruit trees are grown by themselves and without a catch-crop of any kind, weeding is only resorted to in cases where large tracts of level land can be dealt with by means of machinery, as is done in parts of the U.S. A. Weeding by hand is certainly never dreamt of. Returning to the consideration of tropical products. It is clear that the same rule applies as at home to crops which only occupy the ground for a few months. Grains and vegetables, cotton, tobacco and other annual crops require cultivation and the thorough extermin- ation of weeds. But when we pass on to the consideration of more permanent crops like tea and cacao, we find that a number of separate points have to be taken into consideration. In the case of every such crop the question of the growth of leguminous plants age a source of nitrogen and organic matter and the question of forking or other methods of cultivation have to be considered in their relation to the process of weeding proper. But more than this, weeding on tea estates is a problem intimately bound up with the question of the management of labour. and that is a problem upon which we do not propose to intrude upon the present occasion. The controversy over weeding relates chiefly to rubber, and itis to the ques- tion of clean weeding rubber that we propose to devote our attention just now. Here, again, the question of weed- ing cannot be considered without at the same time taking account of the kindred processes of tillage and the growth of leguminous crops. The question of catch crops, too, de- mands attention. And there can be no doubt that the growth of a suitable catch crop under conditions of thorough weeding and cultivation is a process which will pay ifasuitable crop can be found, and if it can be disposed of at a profit when grown. Unfortunately these conditions are not always realis- able in Ceylon. Apart from the question of catch crops, does it pay to clean-weed a plantation consisting simply of rubber? In the face of the assurance of such authorities as Mr. Carruthers and Mr. Kelway Bam- (MARCH, 1909. ber that in most cases it’does not, it may appear superfluous to discuss the matter any further. But, on the other hand, many experienced planters tell us that we must clean-weed, and besides we are anxious to thresh the matter out for ourselves. We feel bound to giveitas our own impression that, where rubber is planted on level ground and stumps can be got rid of within practicable limits of cost, it will pay tocultivate and weed a rubber estate with modern machinery. But it is no doubt the case that on a majority of estates, owing to the nature of the ground, the size of stumps and general monetary considerations, such a method will be found impracticable. Itis the contention of Messrs, Bamber and Carruthers that rubber can be grown with hardly any diminution in size, and at a much smaller cost as com- pared with clean weeding, by a pro- cess which consists essentially in the growth and encouragement of selected weeds. The method consists in weeding only a narrow strip down each row of trees, and encouraging between the rows the growth of some creeping plant which will smother and eventually kill all other forms of vegetation. A point upon which Mr. Bamber lays special stress is the use of the green creepers themselves as a mulch to be applied round the bases of the rubber trees, Here, again, we see the impossi- bility of regarding the weeding question asa thing by itself, the advantages and disadvantages of removing weeds must be considered in connection with other Operations not strictly comprised under the head of weeding. In the ‘report and circular before us various advantages are claimed, and we think with justice, for this method of dealing with weeds. The creepers speci- ally recommended for this purpose in Ceylon are the wild passion flower— Passiflora fotida and Mikania scan- dens. The latter might recently have been observed in the act of demonstrat- ing its powers of smothering other vegetation to a marked degree by anyone travelling up or down the railway _ be- tween Kandy and Polgahawela; and the former is also abundant, though less rampant, in the neighbourhood of Pera- deniya, Extracts from Mr. Carruthers’ repcrt will be found on a later page of the present issue of the 7.A., and Mr. Bamber’s circular has recently been published by the Royal Botanic Gar- dens Department. Wemay leave them to tell their own story, confidently re- commending both these essays to all who are interested in the planting of Hevea rubber. R. H. L, Marcu, 1909,] 211 GUMS, RESINS, SAPS AND EXUDATIONS., IS CLEAN WEEDING ADVISABLE? (Extract from the Report of the Director of Agriculture, F.M.S., for the year 1907). The remarks in my last report as to the value of a green manure plant, of which I gave examples, in the place of the general habit of regularly scraping off weeds and allowing the sun and rain free access to the soil, had little or no effect at that time, but the desire to cut down expenses has caused the sugges- tion to be reconsidered. Weeding on most of the rubber estates inthe Federated Malay States is the item costing most annually. This sum isspent on labour, and represents in many cases 70 per cent. or more of the total labour of the estate. The object of the rubber planter is to obtain as quickly as he can vigorous trees of as large agirthas possible, at the smallest cost, and in order to effect this he keeps his fields as clear of weeds as possible and so allows the rubber tree to have all the moisture and _ plant-food available in the soil. That clean weeding will show a better result in the growth of the rubber trees than allowing all and any weeds to grow continuously, can no doubt be proved. In Perak, however, some of the estates, from want of money or shortness of labour, have not been able to keep their plantations clear of weeds and have abandoned weeding. In some cases the weeds are checked by being regularly cut, but in others nothing at all has been done to eradicate or discourage the weeds. The growth of trees on such places is somewhat poorer than trees in similar conditions which have been kept free from weeds, but the vigour and girth of trees where the weeds have been allowed to grow is not so markedly different as the disciples of clean weeding would expect to see. . The belief in clean weeding is a tradi- tion handed down from English farming to tea and coffee planting in the Hast ; good farming is associated with absence of weeds. In Europe, the farmer of cereals and other crops does not practise the method of using certain plants as a substitute for weeds. There are various reasons why clean weeding in such crops is a good policyin Europe, but annual crops have to be treated differently from permanent cultivations, and the conditions of labour, cultivation, plant growth and especially climate are entirely different in the tropics from those in temperate climates and conse- quently methods have to be modified. The objections to clean weeding in rubber cultivation in the Kederated Malay States and removal of all protec- tion from the surface of the soil, are that it allows a large amount of percola- tion, of heat radiation and of evapor- ation of moisture, also that heavy rainfall on all but flat surfaces always results in the constant removal of very large quan- tities of top soil, which are either carried away in streams or transferred to the drains, Itis not easy to estimate the loss that takes place in tropical climates where soils are allowed to remain ex- posed and frequently scraped. An im- mense amount of plant-food is continu- ally also lost through percolation and drainage; the greater part of this is absorbed by the roots of any plants growing on the surface, and when the leaves and stems of these plants are cut this is to a great extent returned to the soil. With the soil protected from the rays of the sun the conditions of moisture and temperature are most favourable to the development of bacteria which are responsible fur the liberation of plant food. Infclean-weeded land the top two inches or more of soil are, because of admission of heat and light, made impos- sible for feeding roots and the prepar- ation of food forthem. When the ground is covered this surface layer is kept moist and useful for the feeding roots. A considerable area is thus added to the area of soil available for rubber roots and the growth of the trees is improved, In addition to arguments for clean weeding there is a local one, the danger of the ground being taken possession of by ‘‘lalang” (imperata arundinacea), a pestilent weed, which once allowed to invade a plantation can only be eradi- cated at enormous expense. This plant is ubiquitous, is always one of the first to cover newly-opened land, and by far the most difficult weed to eradicate, The experience gained in the use of tapioca as a catch crop in rubber, which obtains on some thousands of acres of rubber showing excellent growth, is another argument in favour of keeping the soil covered up. Few, if any, crops take more from the soil than tapioca, but this loss of valuable plant-food in the soil is to a great extent compensated Gums, Resins, for by the advantage of keeping. the soil from the sun and rain. The girths of young rubber trees grown with tapioca is in many cases as large as those of trees in similar land, clean weeded, and without any other crops. The position thus is: Clean weeding is a costly process, which ensures quick growth ot young rubber trees and pre- vents the land being taken possession of by undesirable weeds. On undulating land it causes loss of top soil, and on all land it means loss of moisture in the surface layers of the soil. Rubber plants usually grow better in clean than in weed-covered land, because the plant-food and water present in the soil is all available for the rubber and is not used by the roots of various other plants which are useless to the planter. The high cost of weeding and the fact that, with a not too abundant supply of labour, the majority of coolies are employed at this work, both point to the desirability of some other method not less helpful to the growth of young rubber, if such can be found. Though figures of cost of weeding vary very greatly, on some estates the cost two years after the land has been opened is not under $2 per acre per month, or $24 per year, This represents on an estate of 1,000 acresa cost of $24,000 per year, and a probable cost for weeding of nearly $100,000 before the rubber is in bearing. In labour it represents a continual force of about 250 coolies working for 3800 days in the year. I have for the last three years been investigating the question of asubsti- tute for weeds which will reduce the wage bill without reducing the rapidity with which the rubber trees grow, and mentioned in my annual report for last year three plants which observation and experiment show to be suitable and therefore worth a serious trial on every estate. These three plants belong to the order Leguminos, the clover, pea and crota- loria tribe,a group of plants many of which are characterised by the posses- sion of bacteria on their roots. These bacteria, the life history of which has been investigated fully by a large number of botanists and agriculturists, live in what is technically called sym- biotic relationship—7.e., both host plant and bacterium being of mutual service to each other. In a report of this character itis unnecessary to more fully explain this point, but it will suffice to say that the bacteria which form charac- teristic nodules on the roots of the host “ie 212 [Marcu, 1909. plant, take nitrogen from the air, and this nitrogen is afterwards available in the soil as plant-food. The amount of nitrogen thus added to the soil varies with the species of the bacteria and their numbers, but in the case of one of the plants hereafter mentioned experiments have shown it to be as much as 200lbs. per acre per year. Leguminous plants which possess these bacteria may therefore be considered as friends and not as foes, as_ useful plants and not as weeds in a rubber plantation. In order to get the maximum of benefit from these plants it is necessary to cut them down periodically and leave them lying on the ground. Thelength of time they should be allowed to grow depends on the vigour of the plant, in most cases about nine months. This cutting down need not be an ex- pensive operation, as it is not intended to eradicate the plant, but only to allow the green parts to form amulch on the surface of the land and thus return something to the soil. The operations of weeding must, as the planter knows to his cost, be carried on periodically and not be delayed, or the weeds will get out of hand, and the cost of eradication be very greatly increased or made well nigh impossible, but the cutting or hacking down the leguminous green manure plants may be postponed without danger until such time as labour is available for the purpose. The three plants which seem to me most suitable in Malaya for the purpose above mentioned are: Crotalaria striata, Mimosa pudica and Desmodium trifto- rum. Crotalaria striata is a quick-growing vetch-like plant with trifoliate darkish green leaves. In good soil with sufficient rainfall it grows to a height of 6 feet in about a year. When sown sufficiently thick it completely covers the ground within a few weeks, so that the clearing is like a good lucerne or vetch crop in Europe, and the surface of the ground is not seen at all. It has been proved by experiments with this plant in Ceylon that 14,000 Ibs. of organic matter were formed by crota- laria under cacao, and the nitrogen in this organic matter was equal to that in 1,7000 lbs. of castor cake or 700 lbs. of nitrate of soda. Other plants—weeds —cannot get enough light under the dense cover of the crotalaria, and new weeds are kept out as their seeds cannot reach the ground which is so _ well covered. If the crotalaria is sown in good growing weather, and if the land is clear of all weeds, no further weeding : ’ “ : Marcu, 1909. j should be necessary, but in the case of land which is thoroughly permeated with the underground stems of lalang or with the roots of other weeds it may be found that during the first two or three months weeding is necessary. The crotalaria seed is sown broadcast. As to the quantity to be used per acre it is better to sow more than is necessary than to leave bare patches where weeds ean thrive. Mr. Lauder Watson, who is the first Federated Malay States planter to use this plant in rubber planting, informs me that on Lauderdale, where photograph of crotalaria was taken, he used about 7lbs. I have seen good results from using only 4 lbs. per acre, Mimosa pudica, the ‘‘ sensitive plant,’ which was another of the plants sug- gested in the last annual report, is in many ways the best of all plants to put down as a substitute for weeding. In many cases it has taken less trouble to establish this plant than ecrotalaria, and it thrives extremely well in the Malayan Peninsula on varying soils. ‘I'he peculiar habit of shutting up its leaves when touched is in its favour. When rain falls at all heavily the leaves shut and the water reaches the soil at once, but when the sun shines again the leaves open up and protect the soil from its rays. My experience of this plant is_ that while it grows well on sloping and dry land it seems to enjoy more moist conditions and can be seen in great vigour in ravines and flat places where the moisture is more abundant. Desmodium triflorum, asmall creeping shamrock-like clover, has the advantage that it grows only a few inches high and covers the ground with a turf easy and pleasant to walk on. It is, however, more difficult to establish, and as it seeds very sparingly, it is not easy to obtain any quantity of seed for planting. On one estate some two hundred acres has been successfully laid down with this plant by taking it from neighbouring waste land and planting it as soon as the land was cleared. The question of the best method of establishing one or other of the substi- tutes for weeds or clean weeding is being experimented on both at the Experi- ment Plantations of this department and by various planters who are alive to the great advantages to be gained if they can cover their ground with a friendly plant. By far the best time to establish one of these plants at a minimum costis directly the land has been burnt off. In virgin land after burning no seeds of herbaceous plants are alive in the soil, and any seeds sown 215 Saps and Exudations. or plants planted have no competitors and quickly take possession of the soil. Having once got the plant established all the danger of lalang or other weeds gaining an entrance, and the immediate necessity of putting rubber in is over, since the fields do not get any worse, but rather better for the reception of the rubber plants; and the cost of cut- ting away the crotalaria, mimosa or other plants to putin lines and holes is very little. Drains are not necessary or even useful, and thus another expense is saved. The only weeding necessary is in case jungle trees or shrubs sprout, and these can easily be noticed among the prevalent growth of a single plant and removed. No_ soil is lost from the beginning of the opening of the land, aud the gain in this to the roots of the ruober plant is not to be neglected. The chief arguments, and they are - many and constant, against the adop- tion or even the trial of the abandon- ment of weeding in tavour of a green mabure are: That it has never been done in rubber or in other’ tropical products, an argument which is always used to disccurage any new departure. That the plants suggested will take possession of the land to the exclusion of other plants—weeds. This can be met by an appeal to experimental piots, and as far as I have observed where care is taken and money spent, even in two or three-year-old clearings, these plants can be establishedina short time. It must be remembered that even if 30 per cent. of the surface of the land is covered by harmful weeds, and the rest by one selected plant, it is probable that the rubber will grow more vigor- ously than in clean weeded fields, and with no cost for weeding. That the thorns on the Mimosa will be a nuisance’ to coolies getting about the estate. This argument is used without considering that by putting in green manure, the number of coolies whose work will take them. into the field is very small and their legs can be pro- tected. The only reason why coolies are needed ina field properly covered by the green manure is to search for white ants and to put in any supplies; the latter work will very probably be lessened by the fact that the shaded ground gives very much better conditions for the growth of the young rubber plants than its exposure to sun and rain. That the appearance of an _ estate would be against it in the eyes of a valuer, The answer to this is that when the valuer or retired planter, to whose Gums Resins, mind such methods are worse than sacrilege, sees that the growth of the trees is as good as before,and remembers the money that has been saved, he will no longer consider bare soil the acme of zood planting. The chief argument thatI have per- sonally met with among planters is “Yes, if you could convince my ‘V.A.’ or my Directors, but unless they are convinced I am _ powerless,” but this difficulty can be removed by the planter clearly showing by measurement of trees and tigures of decrease of cost-on a small plot that the method is correct. Itis difficult to remove fixed and long stand- ing views as to tropical cultivation from the minds of men who have experience, but the stern tacts of dollars and cents saved without diminution of vigour in the rubber trees when shown will convert. Before leaving this question I may be allowed to quote from Dr. E. B. Vorkee’s recent work on agriculture published during last year. This is written in regard to American agriculture, where the conditions are not so unfavourable for clean weeding as in tropical countries with a heavy rainfall. “¢ To keep the land constantly occupied with growing plants is particularly im- portant, both in the hot summer and in fall and spring. The covering of the land in summer prevents the temper- ature rising so high as to destroy the organisms iu the soil, while the covering in fall and spring prevents the mechani- cal losses that occur from wind and rain and by the carrying away of food in the soil water.” Dr. Alfred Russel Wallace, whose name will always be associated with Malayan regions, writes to me in regard to the protective forest belts which have been, and are being, laid out through the Federated Malay States: “They prevent the loss of soil which can never be replaced.” The italics are Dr. Wallace’s. Thisis also true of the soil lost by clean weeding. On some estates there are growing among the weeds leguminous plants which possess nitrogenous nodules on their roots, and it may be possible in these cases for coolies to be shown how to leave these plants in weeding, so that ina short time they may get entire possession of the field and weeding may be discontinued. Leguminous plants can often be recognised by those unacquaint- ed with botany, their leaves being divided, and in appearance like those of the vetch, pea, mimosa, cassia or crotalaria, 214 [MarcH, 1909. As the chief cost of an estate until its profit-earning period is that of weeding, any suggestion as to the reduction ot that prime expense should meet with consideration. If every estate would set apart a portion of their newly-opened clearings for an experiment with a green manure, keeping a record of the cost of putting the land into Crotalaria, Mimosa, Desmodium and whatever other useful plant is selected, and recording the money spent on adjoining land cultivated on the existing clean-weeding method, and carefully measuring the trees on each place to see the relative progress, I have little doubt that the benefit of keeping the soil covered, instead of constantly scraping off the weeds, will be seen. That the planter should adopt sugges- tions made by scientific experts without weighing them carefully is not to be expected, but what is wanted is that each practical man should satisfy himself by careful trial that this proposal in regard to cultivation of rubber estates is feasible. Even if this experiment results ira loss of money and the destruction of a few acres of rubber he cannot be blamed in making it, considering the large economy thatis to be effected if it is proved to be successful. WEED KILLING BY SPRAYING. The experiments in regard to the eradication of lalang and other weeds by means of spraying with a solution of arsenite of soda were carried on both by the department and by several planters with encouraging success. The difficulties in regard to the pro- hibitive cost which was charged locally has been to some extent overcome, and supplies of this substance were obtained from Calcutta at one-fifth of that charged in the Federated Malay States. This cost is, however, too great ; it can be obtainedin England at a cost, in- cluding freight to Port Swettenham, at about 12 cents perlb. Asthe chief cost in this method of destroying weeds is the cost of the material used in the spray, it is mostimportant to obtain the arsenite of soda as cheaply as possible. The difficulty in regard to sprayers has also been toa great extent overcome, and though itis not yet possible to get suitable sprayers locally, yet some English and American machines at varying prices from $1 for hand sprayers to $250 for steam power have been in- vestigated and shown to be suitable to the purpose. ~Marcu, 1909.] While the use of arsenite of soda was first investigated, as mentioned in my last report for the eradication of the most pestilent weed, lalang (/mperata arundinacea), this method of getting rid of weeds is still more efficacious in the ease of other weeds submitting a larger and flatter surface to the spray. The leaves are all killed within 48 hours, and should be left to rot onthe ground and not pulled out or scraped away; by this means the soil is protected from rain and sun, andif the plant becomes green it can be again sprayed. The cost of this method of destroying weeds necessarily varies with the character of the fields to be sprayed, but in most eases with hand atomiser sprayers the cost should not be 50 cents per acre where very weedy, and on ordinary fields probably not more than 10-15 cents. A series of experiments near the labora- tories of the department are in progress to estimate the cost of eradicating lalang by the following processes :— 1. Spraying with arsenite of soda; 2. Digging and picking out all roots 3 ne re-chungkoling ; 4. The introduction of Passiflora foetida, ‘‘ wild passion flower,” a vigorous creeping plant which smothers lalang and can itself be easily removed. These are being carried out in various ways on some ten l-acre lots and the exact cost in each case recorded.

By F. G. Scott. On ordinary Cacao soils Casli/loa elas- tica should be planted about 20 ft. apart, and on very rich soils about 30 ft. When possible, holes should be prepared in March, about 8 feet deep aud 2 feet wide, and filled with equal quantities of earth and stable manure which would help the young plants to become quickly established. They should be putin about three months after preparation of the holes so as to allow the earth to settle, which would be in June, the beginning of the rainy season when the field has received one or two showers, for if plant- ed later it might become too saturated and would tend to rot the young root- lets, consequently killing the plants, which is often the case when forming 215 Saps and Hxudations. estates. If the plants are in bamboo pots it should be always removed as it allows the plant to spread its roots much quicker. The best way to remove the pot is to take hold of it in the left hand anda cutlass in the right; allow it to be at right angles to your body, the plant facing you, and give three fairly quick sharp blows with the cutlass so as to strike it in a different place each time; then remove the three broken pieces together with the small gravel at the bottom of the ball, taking care that the earth does not break up. Castilloa elastica grows best under partial shade, and would thrive well along the boundaries of a cacao estate, provided they are planted at proper dis- tances and not intended as wind-breaks. Where trees are exposed to wind ‘Funtumia elastica could be planted with advantage, not only as a wind- break but as a rubber-producing plant.— Trinidad Botanical Department No. 60, October, 1908. CAMPHOR AND ITS BY-PRODUCTS. DISTRIBUTION OF CAMPHOR TREES. The growth of this important tree is limited in Japan to the south of 36° north latitude. On the south coast of the Main Island, Shikoku, and Kyushu, the trees are met with only in the compounds of shrines or temples, or in gardeus, where they have been preserved from felling. As the distillation of camphor became common, the felling of the trees in- creased, and forests of this valuable trees were greatly reduced in area, but a few old specimens were fortunately pre- served. The propagation of this tree is in no way neglected, so that the production of camphor will increase in the course of years. Formosa has at present an exten- sive supply of these trees, as there, in districts not yet explored, huge trees are still found in their primordial luxuri- ance, CAMPHOR-TREE PLANTING. In raising camphor trees, seedlings are obtained by sowing the seeds directly in a wood. Small holes are dug in an already well-grown forest of evergreen oaks or red pines, and four or five seeds are put in each hole. The shelter of the trees favours the growth of the seedlings, In fifty years trees so planted will attain a diameter of one foot when they are large enough for the produc- tion of camphor. In many places attempts have been made to grow Gums, Resins, 216 the tree by transplantation, but with- out suecess, In other places, in order to obtuin leaves to produce camphor, the so-called ‘‘ coppice-planting” is practised, and it will be of advantage to this industry. CHEMICAL PROPERTIES OF CAMPHOR. Every part of a camphor tree contains camphor, which is obtained by dis- tillation. Camphor is a white semi- transparent amorphous substance with a specific gravity of 0°987, and with a peculiar smell. Whenit is tasted it gives a sharp flavour, turning into a cool one. When plunged into water it forms circles, and when lighted it burns, floating on water. It is almost insolub.e in water, but readily dis- solves in alcohol, ether, acetone, chlorotorm, acid, and volatile oil. Camphor is found as crystals in the tissue of the woud, and by double distil- lation is separated from the crude oil, the product of the first distillation. It is an oxidized product of camphor- genotol, which forms the principal of the camphor oils of commerce. CRUDE CAMPHOR.—This substance is obtained as crystals by the distillation of camphor chips or camphor leaves in the presence of water vapour. It is separated as such after sufficient distil- lation, and subsequent liberation of water and oil. It is adark-coloured sub- stance, and fuses at 170° C. CrupE CAMPHOR O1L.—This substance is obtained as a liquid in the separation of camphor, with which it comes out simultaneously. Camphor and other by- products are afterwards separated fiom this substance. WHITE O1L.—This is a white oil with a specific gravity of 088 at 15°C., obtained by sublimating crude camphor oil. It distills below 188° C., and is used in soap-making, &c. ReEpD O1n.—This substance, like white oil, is obtained from crude camphor oil. It has a specific gravity of 1°020 at 15° C., and fuses at 170° C. Biack O1L.—This substance also is obtained from crude camphor oil. It is a black liquid, having a specific gravity of 1:007 at 15° C.; it is extensively used in varnishing substances. TURPENTINE.—Like varnish, this sub- stance is obtained from white oil and is extensively used for medical and indus- trial purposes. SuFFROL.—This is a colourless trans- parent substance obtained from red oil. It has a specific gravity of 1:108 at 15° C. (Marcu, 1909, It fuses at 225°C. It is extensively used in making perfumery and soap. ‘ DISINFECTOR.—This substance was dis- covered by Dr. Shimoyama Junichiro in 1901. It is obtained by the partial distillation of red oil with which a few other ingredients have been mixed. It is a brownish, heavy liquid, having a specific gravity of 1:082 at 15° C., with very strong antiseptic properties. A solution of one part in 100 of water easily kills the cholera bacillus and the plague pact The price in Kobe is 0°35 yen per Ib.* Insgector.—This substance was also discovered by Dr. Shimoyama Junichiro, and is obtained by a process similar to that used in obtaining ‘‘disinfector.” It has a specific gravity of 0°987 at 15°C.; mixed with water it presents a milky white appearance, and is strongly anti- septic. A solution in 100 parts of water is efficient in killing insects injurious to various farm crops. The price in Kobe is 0:24 yen per lb. REFINED GRANULAR CAMPHOR.—This is a product of sublimation of crude camphor. It fuses at 174°C. The price in Tokyo is 0°85 yen per lb, REFINED CAMPHOR.—This substance is the refined product of ordinary crude granular camphor by sublimation and subsequent compression. It fuses at 175° C., and costs 1:00 yen per lb. in Tokyo. REFINED CAMPHOR TABLETS.—(‘“ Fuji- sawa Camphor”).—This form is obtained by the distillation of crude camphor under suitable pressure. The price in Tokyo is 1°70 yen per lb. By the provisions of the Law of the. thirty-sixth year of Meiji (1908) the sale of camphor produced in Japan is mono- polized by the Government, by means of restricting the sale of crude cam- phor and camphor oil. The annual production of camphor in Japan is 6,000,0001lb., and is exported in great quantities; 1,500,000 lb. is pro- duced in the Main Island, Kyushu, and Shikoku, and the remaining 4,500,000 lb. in Formosa.—Tropical Life, Vol. IV., No. 12, December, 1908. LAC IN THE EASTERN DUN, U. P. By G. N. GRAHAM YOUNG. The life history of the insect is now well known, but there are some facts I would place on record gleaned from in- vestigations made personally in the Eastern Dua, * One Yen = 2s. 04d. MARCH, 1909. | In this locality there are two broods, and the lac is collected during the first half of July and from the last week of October to the end of the first of November. The young swarm generally by the end of the second week of July and of the first week in November, but the time of swarming varies consider- ably in different seasons. A good deal depends onthe weather, fora normal season the broods swarm during the periods mentioned above, but should the season bea dry one, and the rain hold off, theswarming will be delayed. About six weeks to two months after swarming the males appear, but they are few in number in proportion to the females, so that in order to fertilise every cel], each ¢ must be able to im- pregnate 1009. Males without wings are to be seen in both broods, but they are scarce in proportion to the winged forms. Itis erroneous to contend that one brood is winged while the other is not. The cells are attended by several species of ants, some of large size, and these swarm over the branches in myriads, but appear to do absolutely no damage to the insects. On thecontrary they afford the cells a considerable amount of protection by attacking and driving off any insects that happen to alight on the branches. Asa proof of my statement I would ask the reader to grasp atwig containing lac and note the behaviour of the ants. I think he would not care to repeat the experiment. It would serve no good purpose to attract the ants from the trees by placing something more toothsome at the roots, and the cost would probably take away all the profit. The presence of antsis an indication that the lac is healthy, and vice versa. The pests most to be feared are moths, and ot these I have noticed species Gal:ria and Enblema. The larvee of these are to be found in both broods and practically all the year round, There appear to be several generations of these moths in the year, for I have found larve in several stages of develop- ment as well as pupe in a single stick of the lac and at different times of the year. Inthe first week of April I got a group of twelve white eggs, which were laid on the side of my rearing jar by a Enblema sp. moth which issued in the third week of March. A new species of Ichneumon fly has been reared from infested lacand has been sent to England to be named. This fly, it is hoped, is parasitic on the Enblema sp. The damage done by these moths is very 8 217 Saps and Exudations. considerable, and 1 have known them to entirely destroy the cells on a tree. These moth pests are certainly on the increase, and given favourable con- ditions they may entirely destroy the lac in aforest. The next greatest enemy to lae is frost, In the Dun lac is pro- duced entirely on B. frondosa which is badly affected by frost, and almost all the tender twigs are killed by it during the winter, so that only one good crop can be expected annually. Fire does a great deal of damage, if the area is not carefully pro- tected. Wind may do serious damage at the time of swarming, and violent wind is always harmful] ; a gentle breeze though greatly helpsin the spreading of the young from tree totree. Inthe ease of drought, the insects may be killed at the time of swarming. Monkeys do not, as is supposed, eat the lac, but if they are watched it will be noticed that the damage done is only out of curiosity and wanton mischief, At Pathri in the Saharanpur district there isa large forest area which is composed almost entirely of B. frondosa, which would yielda large quantity of ‘lac were ittaken in hand. Some experi- ments have lately been carried out by private individuals, but owing to the adverse conditions made by the Forest Department they have been compelled to abandon the experiments. One of the conditions laid down was that grazing be allowed, and this re- sulted in the forest being burnt and entailed a heavy loss on the experi- menter. Brood lac should be cut from the trees about a week before the swarming begins. In order to fix on the correct time itis only necessary to break open afew cells and examine them with an ordinary magnifying glass, when if the young can beclearly seen and if the colouring matter has become of the consistency of treacle, they are within a week of swarming. When infesting trees, say, of an average height of 25 feet and well branched, itis sufficient to apply 4 lbs. of brood to each tree. The brood should be tied lightly in bundles, each bundle to contain three sticks, about a foot long. These bundles should be tied on the upper surfaces of the branches, and about three-fourths the way up and near the tender twigs. Itis not of any advantage to use straw with the bundles, but care should be taken that the sticks of brood lac lie along the upper surfaces of the branches to which they are tied. The bundies of brood should be fixed by a tie at either end and not in the middle, Gums, Resins, The lac froma Ficus sp. have been _known to take splendidly on B. frondosa ; and the B.frondosa lac young have been carried by the wind to the garden lichi tree and thrived so well as to necessitate the infested branches being cut in order to save the fruit.

THE CASTOR-OIL PLANT. (Ricinus communis, L.) By HAROLD CUZNER, Bureau of Agriculture. The castor-oil plant (tangan-tangan, Tagalog), the seeds of which furnish the castor-oil of commerce, is probably a native of Africa, although it is found growing wild in many tropical countries. It has been so long in cultivation that nothing is accurately known as to its original habits. Long before the Chris- tian era it was cultivated in India, and its medicinal properties were known. Its seeds have been found in ancient Egyptian tombs, and its cultivation is described in the writings of the Romans. In Europe it was cultivated by Albertus Magnus, Bishop of Ratisbon, in the middle of the thirteenth century, and it was known as a garden plant in the time of 'Turner (1568), who mentions the oil as ‘‘oleum cicimum vei ricinum.” At the close of the same century Gerardi was familiar with this plant under the name of ‘‘ricinus” or ‘“ kili,” the oil of which, he states, was used in the treatment of diseases of the skin. After this the plant seems to have fallen into complete neglect, in 1761 the seeds being rarely found in druggists’ shops and the oil scarcely known. In 1764 it was again brought to notice by Peter Cavinano, a physician who had practised for some time in the West Indies, in an article entitled, ‘*Dissetration on the Oleum Palmz _ Christi, sive Oleum Ricini,” in which he recommended it as a purgative. The seeds were admitted to the Lon- don Pharmacopeeia in 1788, and direc- tions given for preparing the oil. At this period and tor many years there- after the small supply of oil required in Europe was obtained from Jamaica, but it has gradually been displaced of late years by the product of the East Indies and India, where, it is stated, 830,000 acres were devoted to the growing of the bean in 1890. The plant is also cultivated in Africa, Italy, Central and South America, and China, and in the United States in Kansas, Oklahoma, Wisconsin, Oregan, and California. In these Islands it is not cultivated, but has grown wild in all parts of the Archipelago, and in some sections of Negros and Midanao is Tear ae to be taking possession of the and, There are two forms of the plant, 2.e., the large and small-seeded varieties. The large-seeded varieties give a rather large amount of inferior oil, which is’ used for lubricating, ete., while from the small-seeded varieties the medicinal oil is obtained. Kurz states that the plant yields a white resin, but as no other writer alludes to this it may be said not to exist in any quantity worth considering. Aside from its use as an oil plant, its principal value is as a food for the “eri” silkworm in Assam, though itis stated that paper pulp may be made from the stems and bark. The seeds yield, on the average, from 46 to 53 per cent. of oil, though there are occasional records of 60 per cent. It is a thick, viscid oil, with a specific gravity of about 0:964, The pharmaceu- tical product is almost colourless, while the inferior grades are of a greenish-yellow hue. The odour and taste vary from the nearly odourless and tasteless oils of the better grades to the nauseating ones of the poorer grades. It is used for dressing leather, for lubricating, and, in India, to some extent for lighting purposes. Soap anda mordant for Turkey red dye are also made from the oil. The oil saponifies easily with caustic soda and yield aclear, soluble product which is used in the manufacture of the cheaper grades of transparent soap. However, itis not likely to be looked upon with much favour for this pur- pose, asit has a tendency to become rancid in keeping, and owing to its being extremely soluble, as stated above, it is very wasteful. The mordant for the Turkey red dye is made by treating the oil with sulphuric acid in the proportion of four parts of oil to. one of acid, It should be stirred continually until thoroughly mixed, to avoid a rise in’ temperature; then allowed to stand twenty-four hours and washed to get rid of any fatty acids. The exportation of oil and beans from India for the years 1885-1887 is given as follows :— , Oil. Seed. Year.

Two hundred pounds of nitrogen in the form of castor pomace costs $840 more than the same amount in cotton-seed meal, so that the net profit, provided the quality of the crop were the same, would have been $5°47, but this was not the case. Another use that is sometimes made of the cake in India is for making gas to illuminate the railway stations. CULTIVATION. The method of cultivation followed in Madras, outlined in a circular of the Royal Botanic Gardens, Ceylon, is probably as good asany. There the land is ploughed twice after rain, and the seed dropped in the furrow and covered by the plough following. A month later, when the plants are a foot high, the land between the rows, which are a yard apart, is ploughed again. The crop of beans is often followed by either pea- nuts or corn. The only improvement to be suggested on this method is that the field be given instead of 3 feet apart. In Hawaii, according to Agricultural Press Bulletin No. 2, quite a different system is followed on some farms situ- ated near the sea level. After prepar- ing the land, the seeds are planted at distances of 15 feet in rows 20 feet apart, which gives 150 plants to the acre. As soon as the plants are 2 feet high the terminal bud is ripped off so as to force the production of lateral shoots, which are in turn shortened to compel the plant to branch as much as possible and keep down the height, so that the spikes may be harvested tiom the ground and in order to increase the number of bear- ing shoots. The plants begin to flower when from eight to nine months old, and the seed matures in about ten months. During the growing period the plants should be well cultivated. Under this system the crop is kept growing and should pay commercially for from five to seven years, but during that time must receive occasional dressings of manure, {Marcu, 1909. oF = $75 to $80. Marcu, 1909.] 231 The spikes or seed clusters should be gathered as soon as ripe, which is indi- cated by their beginning todry up, split open, and throw out the seed. After picking, the spikes may be spread on a_ piece of hard, smooth ground and turned occasionally so that they will dry rapidly. Where there is danger of rain while the seeds are dry- ing, it is necessary to have a proper house with shelves made of slats on which the spikes can be placed and stirred cccasionally, the openings between the slats allowing the beans to drop through into a trough below where they can be easily collected. Profits from the crop are not gener- ally large, as 12 bushels to the acre is considered an average yield in the United States, and they sell there for from $0°75 to $1 per bushel. In Hono- lulu, however, the crop is stated to be from 2,500 to 3,000 pounds per year, while the maximum yield for Madras varieties is given at from 400 to 450 pounds per acre. The Honolulu report goes on to state, however, that the gross returns per acre seldom exceed From this it would seem that as the plants must be grown on good land in order to produce a success- ful crop, it is hardly to be reeommended toan already flourishing community ; though a rank, strong-growing plant, it does not necessarily deplete the soil badly, as all the plant food taken up by the leaves and stalks remains in the field, only the spikes and seeds being removed, and these spikes or their ashes may be returned to the field after the beans have been threshed out. It has been found that 100 pounds of dry spikes yield about 55 pounds of beans and 45 pounds of pods. As to whether or not it will pay the cultivator to return the pods to the field may be judged from the amount of fertilizer contained in them. Hight hundred pounds of dry pods contain about13 pounds of nitrogen, 46 pounds of potash and 14 pounds of phosphoric acid, thus more than equaling in fertilizer value the same weight of ordinary wood ashes worth $10 per ton. One thousand pounds of beans, on the other hand, remove 80 pounds of nitrogen, 4 pounds ef potach, and 14 pounds of phosphoric acid. ENEMIES OF THE CASTOR PLANT. The circular of the Royal Botanic Gardens of Ceylon gives two insects as being injurious to the plants, one a caterpillar, Huproctia guttata, Wlk., which, though omniverous, shows a partiality for the leaves of the castor plant, and the other, the green fly, Oils and Fats.

It has been brought to my notice on one or two occasions recently that the Sin- gapore market price of Copra is nearly always less than that quoted for Ceylon and the Pacific Islands. In order to ascertain the reeson for this I recently made caretul enquiry into the state of the market and the quality of the Copra offered for sale. What surprised me most was the very poor quality of the Copra imported trom the surrounding Islands and the Malay States compared with that from Java and other Dutch Islands. After examining numerous samples taken from consignments from many different parts I am not surprised that Singapore prices do not compare favourably with those of other markets. _ There are several causes which account for the inferior quality and price of local copra. The principal cause ap- pears to me to be the absence of some system of supervision over the native and Chinese growers. I believe that in Java and other Dutch Islands the Dutch Government examines all Copra_ for export and only that which is up to standard quality is allowed to be ship- ped. Thisina great measure accounts for the excellence of Dutch Copra, The second cause is that it is common prac- tice to pick the coconuts before they are quite ripe, thus accounting for the large quantities of thin, soft and decay- ing Copra on the market. Quantities of good ripe Copra are frequently ruined by mixing it with this half-matured stuff. _The third reason is that the Copra is badly dried. That said to be sun-dried is only partially dried, and_as soon as put in bulk becomes mouldy and rots. That said to be kiln-dried is practically roasted. A -fourth, and by nO means least important, reason is the absence of any form of beneficial culti- vation on the estates. In the majority of instances trees are never by any chance manured nor is any form of bene- ficial cultivation practised. The result of this neglect is an inferior Copra poor in oil-producing qualities. I am now referring to Malay and Chinese- owned estates which comprise prac- ticaly the whole industry. It is well known that European-owned estates produce Copra of the very highest quality, but unfortunately “for their Owners, the poor quality determines the market price, Oils and Fats. Ceylon Copra obtains a better price chiefly because the large majority of coconut estates there are owned by Europeans and under European man- agement, and every care is taken to turn out Copra of first quality, The Pacific Islands Copra maintains its advantage in price principally because Messrs. Lever Bros. and other well- known soap manufacturers have exten- sive interests there. They have repre- sentatives on the spot who insist on first- class Copra being supplied, and in return pay the highest price. The difference in price between good and bad Copra in Singapore is about $1 per picul. The present price for first quality isabout $7°50. As the price rises it is customary for many native and Chinese growers to resort to the inju- rious practice of rushing quantities of unripe badly dried Copra on the market in order to catch the higher rate. This is a practice which cannot be _ too strongly condemned. The principal sources of supply are Dutch Borneo, the Natunas and Anam- bas Islands, Johore, the Malay Penin- sula, and the Dutch Islands generally. Singapore produces over 3,00C piculs of Copra per month chiefly from Tan- jong Katong and Passir Panjang. This, with the exception of a small quantity from Kuropean estates, is badly dried and contains a large percentage of un- ripe nut. Dutch Copra_ from Billeton and Banka is principally kiln-dried and arrives clean, well.dried and of good quality. That from Padang, Sumatra, is in small pieces well ripened, dry, dark and oily in appearance and contains more oil than any other Copra imported to Singapore. This is due to careful culti- vation and none but well-matured nuts being gathered. The Celebes give us a good Copra, well dried from fully matured nuts, yields an excellent oil and shews careful preparation. Asahan exports fine large Copra, ripe and fairly welldried both by sun andkiln. Pontianak produces dry Copra cf tair quality containing a small percentage of unripe nut. Saigon (Singkawang) Copra is of good quality, dry, and shews careful pre- paration. 222 (Marcu, 1909. Ternate Islands Copra is very good, generally dry. Kelantan Copra is good, but that from Johore (Batu Pahat) is very Wet, unripeaudmouldy. Rhio sends good samples of Copra but occasionally the quality cannot be depended on. Ihave recently seen shipments from Malacca and Muar which were very bad indeed, in fact it is said that Copra from these two places is the worst sent in to Singapore. In one store I saw several lots heating so badly that it was im- possible to bear the hand between the sacks. Quite half was unripe and little or no attempt had been made/at drying. Iam informed on good authority that the quantity of bad Copra from Malacca is steadily increasing, Selangor Copra from native and Chinese sources is of fair quality but contains a good percentage of unripe put, also sand aud other impurities. The exports of Copra are to Russia, France, Spain and other continental ports, and recently to the United Kingdom. The exports of coconut oil from Singapore in 1907 reached 159,801 piculs, of which 40,163 piculs were im- purted chiefly from Pontianak. The imports into and exports from Singapore ip each of the five years 1903 to 1907, and for nine months of 1908 are :— Year. Imports. Piculs.

Recent drop in the quantity and value of cutch exported._Some apprehension has of late been caused by a marked decrease in the quantity and value of cutch* exported from Burma during recent years, for which various reasons have been assigned, and asa result of a detailed enquiry which I have recently had occasion to make in the matter, it may be of interest to consider the facts elicited, particularly as to bearing on the probable future of the cutch trade. A glance at the figures in Appendix A. will show that the net export value of Burma cutch is now considerably less than it was ten to fifteen years ago ; it reached avery low figure in 1904-05, but has recovered slightly since then. The coasting trade, on the other hand, does not show the same marked tendency to decline in net value, though the quan- tity now handled ismuch less than it was formerly. Drop in local prices.—The local up- country prices of cutch have also shown a serious decline. Thus at Pakokku, one of the local centres of the ecutch trade in Upper-Burma, cutch sold a few years ago at Rs. 50 per 100 viss, + whereas of late the price has dropped to Rs. 25 to Rs. 30. Temporary fluctuations in the value of cutch have been of frequent occur- rence in the past, and are bound to continue so long as the supplies fluctu- ate so much as they have done and still continue todo. Thisis inevitable, because there is but a limited consump- tion of cutch, and any production ex- ceeding this amount is followed, as a matter of course, by a decline in price. The permanent decli.e observed for years past is a more serious matter. * Cutch is a brownish coloured extract obtained by boiling chips of the heartwood of Acacia Catechu, Willd. (including two varieties, A. cate- chuoides, Benth., and A. Sundra, C.D,). The liquorobtained by the boiling is further boiled down to the consistency of syrup, poured into moulds, and allowed to harden. The valuable constituents of cutch are a tannin and a crystalline substance known as catechin, andthe value of cutch as a tanning and dyeing agent depends on the amount of these two substances. + 1 viss=3°65 lbs, avoirdupois. Money sunk in cutch plantations and reserves.—Any tendency towards a per- manent decline in the cutch trade is a matter which closely concerns Govern- ment interests. Up to 1907 cutch plan- tations aggregating 8,656 acres have been created and maintained at a total cost, to date, of Rs. 1,46,044, in addition to which 6,696 acres of mixed teak and cuteh plantations have been formed and maintained at a total cost, to date, of Rs: 1,00,487: charging half of the latter sum to cutch, it will be seen that about two lakhsof rupees have already been spent on cutch plantations. Besides this, considerable sums have been spent in forming and maintaining natural reserves of cutch forests, sothat any permanent decline in or total cessa- tion of cutch trade will bea matter of grave corcern, Factors which may account for the de- cline in the cutch trade.—Several reasons have been suggested to account for the decline in the cutch trade. Some of these are of little value, but there are three factors which are worth examining in some detail, and as will be seen below, the tiue reasons for the decline in the trade are to be foundin acom- bination of three factors, which are (1) the limited uses and demand for eutch, (2) substitutes for cuteh, (3) adulter- ation and faulty manufacture. (1) Limited uses and demand for cutch.—Owing to the introduction of cheaper substitutes, the quantity of Burma cutch now consumed is consider- ably less thanit it was some years ago, The world’s annual consumption of Burma cutch probably does not now exceed 4,500 tons per annum, and when this demand is satisfied there is no other outlet for cutch. Moreover, the price must bea low one to tempt importers to purchase in anticipation of future requirements, as the -cost_ of keeping cutech in store in Great Britian, and the loss in weight during about. six months, adds some 10 per cent. to im- porting prices. As thespeculative value of cutch is thus a low one, and as the quantity of cutch manufactured fluctu- ates a good deal year by year, the mar- ket prices of the product must, in view of the restricted demand, also fluctuate proportionally, and this fact explains to a great extent the ups and downs of the cutch market at comparatively short intervals, though it does not entirely explain the drop which has taken place for a long series of years; Dyes and Tans. 224 the latter drop is due rather to the in- troduction of cheaper substitutes. and to the extensive adulteration which took place some yearsago. Cutch is now used chiefly for curing or pre- serving fishing nets, ard sails, the ob- ject of cutching nets being to prevent them from heating, and if they do heat, to prevent the heat from rotting the fabric. Dyers have almost entirely discarded cutch for aniline substitutes. (2) Substitutes for cutch.—The chief products which have severely competed with Burma cutch are mangrove cutch from Borneo and elsewhere, and aniline dyes. Mangrove cutch.—It is believed to be ejyme twenty years since mangrove cutch was first introduced to the fishing in- dustry in Great Britain, but it was not till 1898, as the result of very extensive advertising, that it was used to any greatextent. It hasalso gained a fvot- ing in Holland during the past few years, but is not very largely used. Few fishermen use mangrove cutch alone; some will not use it atall, while others use a proportion mixed with Burma eutch, Mangrove cutch is obtained at a considerably lower price than Burma ecutch, and is Jess liable to fluctuations in price. Although as a preserving material for fishing nets it is inferior to Burma cutch, still it finds favour to some extent because it dissolves readily and gives a red solution without any residue. As mangrove cutch does part of the work for which Burma cutch is used, it affects principally the cheaper qualities of the latter, and lessens the consumption of the cheaper grades of Burma cuteh. For this reason it is most advisable to keep the standard of Burma cutch at the highest possible level. Mangrove cutch is manufactured from the bark of mangroves, the chief of which are Ceriops Candolleana and Rhizophora spp. The trade in this cutch in the Straits is an extensive one, the amount passing through Singapore alone being over 20,000 cwt. annually. The imports into Singapore are from Borneo, Labuan, Sarawak and other localities, not from the Federated Malay States, whilst the imports into Penang are mostly from Sumatra. A large proportion of the mangrove cutch imported into Singapore is used locally and not exported. The Divisional Forest Officer, Rangoon Division, reports a local manufacture of mangrove extract which is not exported but is used locally for curing fishing nets and sails; a similar extract is pre- pared in Arakan. Analysis of mangrove cutch.—A sample of mangrove cutch received from the a . ¥ “qrre [MaRcH, 1909.

STEWART REMINGTON, One of our correspondents sent asam- ple of lalang grass recently to HKngland, and has received the following report, also samples of paper made from lalang grass entirely and half lalang and half cotton :— Certificate of Analysis. This is to certify that the above sam- ple has been carefully examined with the following results :— This grass was forwarded to ‘The Aynsome Technical Laboratories” for investigation, that its commercial use as a source of pulp for paper-making might be ascertained. The object of the present report is to draw attention to the importance and value of this grass as a pulp-pioducing material, and to indicate its chief char- acteristics and economic value. Ihe sample was a pale buff colour, lustrous in appearance and of fair strength, of the order of Gramineze. “The chemical examination furnished the following results, the percentages other than that of moisture being ex- pressed on the dry material :— Moisture BREA | Ash | as ee 414.

AT 41 Length of Ultimate Fibre 1:20 m.m, The ultimate fibre obtained from this grass is very similar in most respects to Ksparto; the yield of bleached fibre being about the same. This is a favourable indication inasmuch as ‘‘ Hsparto” is one of the best known and most useful sources of supply to the trade. The fibres as seen under the microscope are short, smooth, cylindrical, fairly uniform in diameter, gradually taper- ing to rounded extremities; they also occur together in little bundles. The pulp will be found to contain a number of small cuticular cells which do not however shew in the finished paper. The fibres are stained a pale yellow with iodine solution, which fades more radidly than is usual with coloured pulps, The results obtained from the chemi- cal analysis show the grass is capable of yielding a good quality of cellulose, suitable in every way for the manu- facture of paper. Although the grass is very susceptible to the action of dilute alkalis, the final product is ex- ceptionally pure and readily resolved. From observations noted during this preliminary examination the following scheme was adopted for the production of the pulp on a large scale. PROCESS. The available grass in its natural con-_ dition weighing 400 grams (14:1 0z.) was inaclean state, and required little treat- ment beyond cutting into small pieces’ ready for boiling. It is usually neces- sary on a large scale to pass the material through some type of cleaner to _ re- move dirt andadventitious matter. The grass was then thoroughly wetted and soaked until it became soft and pliable. It was placed ina boiler of the spherical type, covered with water and digested with caustic soda corresponding to 15 7 on the grass treated for a period of ten hours under a pressure which was kept constant at four atmospheres; an even temperature about 135° C, being main- tained. Owing to the quantity of material at our disposal being somewhat limited, it was only possible to conduct one experiment, consequently a good margin in the use of caustic and a degree of general treatment was allowed. The pulp obtained after washing was of good uniform quality and colour. The yield agreed very closely and was only slightly higher than the prelimi- nary chemical analysis shewn, which in- dicates complete reaction in the digester. The pulp was carefully beaten for about an hour and at the same time bleached, chloride of lime being used for the purpose; 10 parts of dry powder being used for 100 parts of pulp. The stuff was taken from the beater and _ well washed, and subsequently a small quantity of loading was gradually added and the whole agair beaten for half-an-hour. At this stage of the oper- ation the rosin size was introduced and the decomposition of the soda resinate completed with the calculated quantity ofalum. The amount of size used cor- responded to4% on thedry pulp present, the total time occupied in preparation of the pulp for running on the machine being two hours, Fibres. PREPARATION OF PAPER. No great difficulty was experienced in running the pulp; it retained, however, a considerable quantity of water after passing the suction-boxes, and in conse- quence it was found necessary to keep the press roll down hard. On a large machine this precaution would not be necessary, aS more suction-boxes are available and complete control is assured. The paper was passed over nine eylin- ders at a pressure of about 8 lbs. to the square inch, then through one calendar and finally reeled off. In asimilar man- ner a second sample was prepared, using a mixture of half pulp obtained from the lalang grass and half cotton beaten together. The paper obtained from this blend could prove very useful as a high- class wrapping paper, it being stronger and possessing a comparatively high resistance to folding as will be seen in the following table of physical tests done on the finished specimens of papers. The paper made from ‘‘all-grass” pulp would with judicious treatment for improvement of colour be very suitable for printing purposes.

Some time back inquiries were made by persons interested in the rice growing industry of this colony as to whether the rice straw could not be utilized for the manufacture of paperin the same way asthe straw of other cereals, viz., 230 [MARCH, 1909, rye, wheat, oats and barley is employed in countries where these are grown. The following note from the ‘‘ Louisiana Planter and Sugar Manufacturer,” Vol. XL., No. 25, provides an answer to this question, and shows that by the estab- lishment of a pulp mill, paper pulp might be produced locally for shipment to paper mills to be there manufactured into paper. ‘Rice farmers have long been in search for some better use for the straw than feeding it to stock for which it is worth very little in the way of nourish- ment. Recent advices from Beaumont, Texas, state that Mr. W. D. Wing, a pro- minent capitalist of Bangor, Maine, be- came interested in the proposition of making paper pulp from rice straw, and to ascertain the elemental qualities of the straw in this respect he sent some of the straw to a chemist for pulp mill in Boston, and had some sample paper made from the straw. During his recent visit Mr. Wing exhibited these samples. Notwithstanding they were made entirely by hand in a laboratory, the samples proved to be excellent quality of paper, capable of retaining ink and suitable for many purposes for which paper is used. Mr. Wing owns a large amount of stock ina pulp mill in Maine, and is therefore interested in this matter from another standpoint than to merely make use of the rice straw. His experiments thus far have proved conclusively that rice straw will make an excellent pulp for making paper, and it is his idea that a pulp mill should be built in this terri- tory, and perhaps several mills in different sections of the rice belt for the purpose of utilising this straw. He does not go into the question of building paper mills here, for the reason that paper mills are very expensive, and there may be many questions involved in the operation of a paper mill which are not involvedin a pulp mill. At any rate, Mr. Wing for the present is inter- ested in thepulp proposition, and his plan roughly outlined is to establish these mills, making the pulp from the rice straw, and ship to the paper mills in the New England States. From estimates so far made Mr. Wing believes that the farmer can net $2 per ton for the straw on the farm. This does not include hauling, palin and shipping, but means that the rice farmer will receive $2 for each ton of rice straw produced. Mr, Wing has arranged to ship a large quantity of straw to his mill and demonstrate satisfactorily what sort of paper can be made frcmthe straw. Mr. Wing is not speculating lightly in this 8 Vee \ Marcu, 1909. ] matter, but is thoroughly interested, and if his expectation as to the merit in the straw prove out, he will lose no time in building his pulp mill somewhere in the belt and will ship the pulp to the mill in the north. In addition to the value of the straw for paper making, Mr. Wing finds that there is a large quantity of rice leftin the straw, and from this he believes very many articles of trade, such as alcohol and feed-stuffs can be n.ade. In fact, Mr. Wing believes that rice straw can be utilized almost as much as cottun seed, which not so many vears ago were thrown away, as many farmers now living can remember, As there are about 60,000 acres of rice planted in Jefferson County each season, it will be seen that there is produced about 120,000 tons of rice straw, which, at $2 per ton, will yield $240,040, which has heretofore and would otherwise be thrown away.’”-—-“ Abbeville Meri- dional.”—Journal of the Board of Agri- culture, British Guinea, Vol. LI., No. 2, October, 1908. CARAVONICA COTTON. In Monte Cristo, in the most easterly part of Cuba, 1,500 feet above sea-level, was last autumn planted about fifteen acres with Caravonica silk, and about fifty acres with Caravonica wool-cotton. Although the pianting could not be done till the first days of December, as the seeds ordered from Australasia did not come before that time, the result is most satisfactory for both varieties, The trees have borne and are stiJl bearing very richly. Samples of the cotton have been sent to several experts in America and KEKurope, and from. all quarters the cotton has been praised for strength, gloss, and length of staple. By this enterprise it seems to be proved that of all kinds of cotton, known up to date, the Caravonica is the best one for planting in Cuba, as it pos- sesses a considerable power to resist drought, storm and insect pests, We have planted our trees at the dis- tance of 7 by 7 feet, but according to our experience we will recommend planting 8 by 8 feet, as even at this time--in the middle of September—most trees have grown toa height of 11 by 12 feet, some of them are still higher. We shall have to prune them rather severely for giving them more sunlight and facilitate the picking. After all, the enterprise seems to bea very profitable business. new area is cleared, and when planting the new acreage—which planting is to take place in September--we shall have the great 231 Fibres. advantage of using our own selected and acclimatised seed.—_CUBAN CORRESPON- DENT. This is a very interesting result. Cuba is cooler than Jamaica, and at 1,500 feet the elevation would be equal to our 2,000 feet.—Journal of the Jamaica Agricultural Society, Vol. XII., No. 11, November, 1908. THE FIBRE INDUSTRY. By LEONARD AcutTt, J.P., Tongaat. This industry is not attracting the attention in Natal which it deserves, and I do not think the area of land devoted to aloe-planting is on the in- crease. It is true that extension to some extent is being carried on on the South Coast, but, on the other hand, some large plantations both on the South Coast and in Zululand have been abandoned. Since my first visit to Mauritius, [ have naturally taken an interest in fibre, and it is with much disappointment that I have seen so little doing. I pen these notes in the hope that they will result in more being done to increase our acreage of aloe in the near future. ITam_not wishing to alter anything which I said last year in my ‘“‘ Report on the Fibre Industry of Mauritius,”* but I merely wish to emphasize a few points. which, though I mentioned them in that report, appear to me to be worthy of special attention. In that report (page 1208) I said “The main danger we have here threatening any aloe plantations is that of fire. The cultivation of Creole aloe need only be of the roughest possible description, but a rough cultivation in this country means a quantity of grass and debris which becomes dangerously inflammable in the winter. In Mauritius this does not occur, the grass and debris is not, beyond the small patches, in- flammable at any time of the year. Therefore (in Natal) either cultivation would have to be done to keep down the grass, or we should have to be careful to prevent outside fires coming in, and keep all roads and paths in the plant- ations themselves free of inflammable material.” Now, the first of the above two alter- natives is, at the best, costly, and the other is dangerous and means a great risk, which is not good enough business to attract capital, and it is more than probable that losses by fire have con- tributed largely to the failures of some * October Journal, 1907, page 1199, Fibres. fibre companies or syndicates in our Colony, and the greatest care will have to be exercised in the selection of land and locality for fibre culture, and the most favourable circumstances secured for cultivation and protection from fire. I would not be taken in any way as wishing to discourage the making of plantations. Let us by all means proceed along the lines of regular and systematic planting and cultivation of aloes for fibre-making, and let us be most careful in selection of land, There is a great future before the enterprise, but in watching the progress and prospects of the industry in Natal I am inclined to attach more importance than I did last year toa point which I touched on in my report in the following words :— ‘1 do not doubt that there are many districts in the upper part of the country in which aloes would do well, Many parts of the ‘Thorns’ certainly would suit, and there are thousands of acres which are fit for no other crop, by reason of stones and poor rainfall.” Now, these thorn lands more nearly approach the conditions under which we find aloes growing in Mauritius in that the ground is rich and the climate dry. Moreover, in some districts in Natal I have in my mind’s eye, the stones are so thick that there is never sufficient growth of grass to make such a fire as would injure the aloe plants, but the hills are covered with a growth ot native aloes, brambles, etc., against which the Furcrea would hold its own, and if afew thousand “ bulbils” of this aloe were planted by everybody owning a thorn farm, or even if the bulbils were dropped about, the country would ina few years be as much covered with fibre aloe as the Island of Mauritius is to-day, and a revenue would be obtained at any time when other work was slack. The cost of cutting the leaves and bringing them out of stoney places would be great, but against that would have to be set the fact that they had cost nothing to grow and the collection of the leaves would probably be a class of work which would suit the kraal Kafirs, men, boys, women and girls. Planting, or broad- casting, the ‘“‘bulbils” would be necessary atfirst, but once the plants were old enough to throw up the “poles” with their crop of bulbils the aloe would spread with great rapidity, as the bulbils would be carried by the winds, and would hold their own against any native plants. I have mentioned the idea to several «thorn ” farmers, and I hear that Messrs. Evans, Worthington & Walters at their farm ‘‘N’Kashin” are taking the matte1 upand getting up bulbils from the coast, 202 a ae | -{Marca, 1909, and I feel sure that they will have cause to be thankful that they started the work. What a field there is in the growth of wild aloes in this manner! and without taking up land on which something else can be grown. When one contemplates the poten- tialities of fibre culture in this way, one wonders that the idea does not seize upon the mind of the people, but to dip in Jordan is, of course, too absurdly simple. Hundreds of thousands of acres of practically desert country in the valleys of the Tugela, Umvoti, Bushman’s, and Blue Krantz Rivers might be utilised, and Zululand’ could spare as many acres more and not miss them. I find in my report the following paragraph :— “T think this would be a crop which the native might be encouraged to grow. Young plants might be scattered broad-~ cast in kloofs and sheltered spots in locations; and the aloe might take charge of such places as it has done to such an extent in Mauritius, and prove a source of income in afew years’ time, and make productive alarge area of land on which nothing else can be produced.” I cannot imagine anything better that could be done for our natives than covering large tracts of location lands ~ with aloe; in course of time a large tonnage of leaves would be available, and men would not be wanting to put up machinery and pay a fixed price per 100 lbs. for the leaves, and thus give employment to the swarming population. The * bulbils” are generally procurable for afew shillings per thousand on rail at coast stations. I trust that these few notes will induce everybody with suitable land to plant if only a sackful of plants, which can be done at any time of the year when plants are procurable. Another way in which to cover one’s land quickly would be to get some well grown aloe plants from the coast ; these would flower in a year or two and give enough plants to cover a large area of ground. If Mauritius, a small island, only 34 miles by 22 miles, containing only 456,320 acres, can on its waste land produce £100,000 worth of fibre, asit has done, although the value of the output for the last four years was only £45,000 a year, what could Natal produce on its 16,000,000 acres, exclusive of Zululand ? A great industry is ready to our hand and one not requiring a large outlay. Let us put out our hands and take what is so obviously within ou reach.—Natal Agriculture Journal Vol. XI., No. 12, December, 1908. Marcu, 1909.] 233 EDIBLE PRODUCTS. SUGAR CANE CULTIVATION. PRACTICAL INFORMATION FOR BEGINNERS. We have received a considerable num- ber of requests during the last few months, more particularly from persons who have taken up some of the new sugar lands on the Zululand coast, for information with regard to sugar-cane growing, and, in accordance with these requests, we have pleasure in publishing some ofthe most useful of the infor- mation which we have immediately avaliable. Inthe February and March, 1905, issues of the Journal there were two instalments of an interesting article by Messrs. A. N. Pearson and Alex. Pardy, on ‘‘The Sugar Industry of Natal,” and in the course of that article some practical information was given with regard to the preparation of the soil, manuring, planting, weeding and trash- ing, harvesting, ete. Those issues of the Journal are, however, now out of print, and we accordingly republish such of the information given as will be of most practical value to beginners and others. In early issues of the Journal further articles on sugar-cane cultivation will appear. VARIETIES OF CANE. Besides the Green Natal, supposed to be indigenous, many imported varieties of cane have been introduced. At one time a variety known as China cane was extensively grown, but it suddenly succumbed to a species of smut, Ustilago sacchari, and had to be discarded. The other varieties tried are principally Lousier, Fotiogo, Bois-rouge, Imperial, Tamarand and Belle-ougete, said to be from Mauritius; Ribbon, Bourbon Yellow and Bourbon Purple, probably from Bourbon ; also White Queen (one of. the best in good seasons), Port Mackay, Gold Dust (white and red), and Rose Bamboo, None cf these are now generally cultivated; they have almost every- where been supplanted by a variety the correct name of whichis unknown, but which is here called Uba, a name, it is said, formed of the only letters remain- ing legible on a damaged label attached to the variety on its first arrival in the country.’ Mr. Medley Wood thinks it was introduced by Governor Sir Charles Mitchell, who, on returning from a visit to India in 1884-5, brought two Wardian cases containing cane plants, only three of which were alive. These were pro- pagated by Mr, Wood, the resulting 30 plants being given to Mr. Anthony Wilkinson. It is generally admitted, however, that this cane was introduced in quantity by Mr. De Pass of the Reunion Estate. From a milling point of view, this cane is undesirable; it is thin, tough, wiry and fibrous, and the juice, it is said, needs special care in the treatment ; mill managers say that from 10 to 80 per cent. more mill power is required for this cane than for any other variety. But the planters like it, since it endures the uncertainty of the Natal climate better than any other variety yet tried; it is hardy, bears frost and drought, stools prolifically, recovers readily from locust attacks, is subject to no fungus pests, and but little damaged by white ants and the borer. It is successfully grown on the highlands of the interior as forage for cattle. Within the last few’ years several varieties have. been introduced from the West Indies, British Guinea, Mauritius, Queensland and Honolulu, the Depart- ment of Agriculture having co-operated with the planters for their importation. The Inanda Association have taken a leading part in this movement, and several of the canes have been propagated for distribution on their behalf by Mr, H. W. James,.of Verulam. Some of those from the West Indies were sampled by the Department of Agriculture and analysed. Hitherto it has not been the custom to analyse Natal canes, the chemist, in fact, being. but little recognised by the in- dustry, and therefore no exact com- parisons of the juice of the different varieties as grown in Natal can be made. The following few statements of analysis are, however, available :— Uba Cane. Average. Maximum. Total solids in juice (per cent.) .... 20°32 22°79 Sucrose (per cent.) ... 18°61 20°79 Glucose (per cent.) ... 18 “21 Non-sugars (per cent) 1°53 173 Glucose ratio » 1°00 1:30 Purity wcob OLSGe 9] 2° Per cent. of juice in cane ... 84°28 2°30 Per cent of fibre in cane vis, lowhe 17:70 The above analyses show a large pro- portion of fibre in the cane, but indicate no inferiority in the juice; in fact, the quality of the juice, so far as disclosed by analysis, would not be readily sur- passed anywhere. Edible Products. 234 The West Indian canes grown by Mr. James for the Inanda Association gave results as follow :— B.109 D.95 B.15 Total solids in juice (per cent.) ... 15:31 17:04 16°78 Sucrose (per cent,) ... 12°68 15°83 15°19 Glueose (percent.) .... 1°78 28 37 Non-sugars (ver cent.) 85 O2u ez Glucose ratio fe A417 78 2:46 Purity 82582. 192:9° 1 90°6; The samples were gathered unseason- ably, and the juices were dilute, but the purity and glucose ratio of the last two samples were good. In fact, the analyses generally show that, so far as quality is concerned, the soils and climate of Nataladmit of cane being grown here as well as elsewhere. SOILS. The soils of the planting districts vary considerably, there being light grey sands, red sands, light loams, chocolate loams, sandy clays of all degrees of tex- ture, grey alluvials and black alluvials. Many of these soils may be on the one farm, and even in one cane field. The prevailing soil is a red or chocolate ferruginous sandy loam, light in texture and easy to work whenonce broken up. This class of soil is often very fertile when first cleared of bush, and has been known to give yields in good seasons of four and five tons of sugar crystals per acre from the plant canes. At one time the cane was grown exclusively in_ the alluvial flats, some of which have been in continuous cultivation for 40 years, and still yield well. But many are of poorer quality, and as crops grown in them are subject to flood and frost, it has been found advantageous to plant on the hills, even on the steeper slopes where only hand labour can be applied. According to Mr. Wm. Campbell, ‘“tambootie grass” land is excellent for cane. PREPARATION OF THE GROUND. In newly-cleared bush land the canes may be planted without ploughing. The bush having been cut, the timber stacked and the scrub burnt, holes may be grubbed out with hoe and axe, and the cane planted straight away. Grass land, however, requires to be broken up, allowed to lie for a time, and then cross ploughed and harrowed. For planting old cane lands the ratoons are ploughed out—with the mould board plough, and recently with the disc plough—and the land is then cross ploughed and harrowed. MANURES. Very little manure is used other than mill refuse, but in the reighbourhood of Durban stuff is carted out from the Corporation stables, and in afew cases small quantities of artificials and bone dust are applied. Kxperiments now being conducted by the Department of Agriculture, both on the Coast Experi- ment Farm and on private farms, suggest that many of these lands may be mate- rially benefited by the judicious applica- tion of phosphatic manures. PLANTING. _ The cane is planted in rows five or six feet apart, or even nearer in poor land, and further apart in very rich land. The land is either drilled out with the drill plough working 9 or 10 in. deep, or it is holed out in lines by hand hoes, holes being made 1 ft. wide, 8 or 10 in. deep, and 15 to 2 ft. long, a space of from 6 to 18 in. being left between each. Some- times whole canes are used for planting, these being laid two together in the drills; or the canes are cut into lengths of five eyes to each: many, however, prefer only the tops which have been cut off when the canes are harvested for the mill. These are laid, two, three or four together, in the holes or drills, at dis- tances of 1 to2 ft. apart. The cuttings or sets having been planted are loosely covered with about an inch of soil. As the young shoots grow up, the covering of soil is increased until the drills or holes are filled. The shoots appear in ~ from 10 to 20 days. according to the -weather and the vitality of the sets. The general time for planting is August to September, but it may be done as late as December and January— Natal Agri- cultural Journal, Vol. XI., No. 12, December, 1908. (To be continued.) THE ‘“PULQUE MAGUEY” OF MEXICO. Under the title ‘The Century Plant and some other Plants of the Dry Country,” Professor William Trelease, ot the Missouri Botanic Gardens, con- tributed a highly interesting paper to the ‘“‘Popular Science Monthly” of March, 1907, dealing with the various agaves found in Mexico and their characteristics and uses. This paper includes a lengthy account of Agave atrovirens, or the “‘pulque maguey,” from which the na- tional alcoholic drink of Mexico is pro- duced. The details given below as to the methods followed in the manufac- ture of pulque, and the extent of the trade in this product, are extracted from Dr, Trelease’s article :— South of the city of Mexico, centreing about the little town of Apam, the species of agave is almost exclusively the [MarcH, 1909. > 4 = ple — re aa eh MARCH, 1909. | dark-green giant A. atrovirens, though, as with extensively cultivated plants elsewhere, itis grown in numerous hor- ticultural varieties which look much alike to the botanist but are distinguished by the planter. Over thirty such forms are Said to be planted in the plaius of Apam. As one passes to the colder regions of the north or descends from the table- land into the hot country, still other and different looking species of the same type replace A. atrovirens, which, however, far outnumbers and surpasses them all initsaggregateimportance. These plant- ations of A. atrovirens are the basis of the pulque industry of Mexico—at once a large item in its agricultural wealth and one of the greatest curses of its labouring population. The present traffic in pulque is large. , Something over 5,000,000 barrels of it are used in the Mexican republic every year, of which quantity about half is consumed in the capital city, and much of the re- mainder in Puebla and the other large ' cities of the central plateau. Cheap as it is (for it sells for from 1 to 3 cents of Mexican money for a large glass), its aggregate value amounts. to several million dollars per year. Special trains are run into the city of Mexico every morning for its delivery, as is done with _ the milk supply of American cities, In the Apam district the plantations are chiefly found on the large haciendas or estates. The “ pulque maguey” is a large plant, and its rosette of thick leaves, though appearing to lie next the ground, is really spaced along a stout trunk as large as a small barrel. The whole, charged with sap, weighs several tons. If left to itself, as it is in gardens on the Riviera, where it is called A. salmuiana, like the century plant Agave americana, it produces a gigantic scape, topped with a candela- brum of flowers, when somewhere in the neighbourhood of fifteen years old. This is never permitted on the large plant- ations, for the plant possesses its maxi- mum value when it has reached vege- tative maturity and the scape is about to develop. At the critical moment, known from the appearance of the central bud, this is cut out, andashallow cavity is made in the crown of the trunk, which is covered by a stone, pieces of maguey leaves, or other protection. Into the cavity so formed the sap exudes. It is removed two or three times a day, the surface being scraped and the cavity slightly enlarged each time, until at last nothing but a thin shell of the trunk remains, the leaves meantime having given up their content of fluid and dried to their hard framework—as happens naturally during the flowering period of 235 Hdible Products. all the larger agaves, when the reserve of sap is drawn into the rapidly growing scape and flowers, For a period of three months or more a good plant yields a gallon or two of sap daily, and its total value may be not far from 10 dollars on an average, from which it will be seen that a large maguey plantation represents a considerable item in the assests of a landed proprietor of the plains of Apam. The fluid which collects in the hollow- edtrunk of a cut maguey plant, and is gathered in the manner described, is called ‘“‘agua miel,” or honey-water, be- cause of its sweetness; 9 or 10 per cent. of its weight is sugar, and this furnishes the basis for the alcoholic fermentation which is the chief factor in its con- version into pulque. The ‘‘agua miel” of the Apam district is thin, clear, and colourless, and possesses a rather pleasant taste. The fermentation practices in pulque making are still mostly primitive. I have hada Mexican gentleman tell me that, although when the agua miel was gathered and fermented with due clean- liness he considered it a delicious drink, he would not think of touching pulque as offered, for instance, at the railway station at Apam. The vats used in the fermentation are of ox-hide stretched on frames, and they are usually 3 or 4 ft, wide and nearly asdeep. Fermentation is begun by the introduction of a starter or ‘‘mother of pulque,” obtained by perliminary fermentation, and is car- ried on either without, or at most with little, artificial control of temperature, aud under conditions of positive or nega- tive cleanlinesss which differ with the various haciendas, When marketed, the pulque is a white, decidedly viscous fluid containing about 8 per cent, of alcohol ; fermentation has not been solely alcoholic, however, and its flavour is in part due to changes wrought by bacteria of several kinds which are introduced with the starter in company with the yeast. Continuation of the action of these collateral ferments causes the beverage to spoil ina day or two under ordinary conditions. Where the maguey, though capable of cultivation, yields a lesser or inferior product, agua mielis often more appreci- ated in its unfermented state. As hawk- ed around the streets of Monterey, for instance, in porous earthenware recep- tacles, it is a cool, yellowish fluid, that is very refreshing on a hot day, and the limpid, yellowish, cidery, foamy product of its fermentation in the north is fre- quently more to the taste of the foreigner Fdible Products. 236 than the white, viscous, odoriferous pulque of the Apam district—which alone pleases the adept. Considerable medicinal virtue has been claimed for pulque, and some efforts have been made to specially prepare, bottle, and pasteurise it for medicinal or even table use; but, except in the region of its production, where it is the com- mon beverage, the bulk of it is used as an intoxicant, pure and simple. From it is also produced a rather small quantity of distilled liquor—‘‘ mezcal de pulque.” Mezcal is a term applied comprehen- sively to the liquor obtained by distil- lation from the fermented juices of ayaves. Four or five million gallons of it a year are produced, and its value may amount to some 2,000,000 dollars. The centre for the manufactue of this be- verage is to the west of Gudalajara, and the town of Tequila, situated there, has given its name to the higher grade of liquor, which is clear, smoky, rather smooth, and with a characteristic essen- tial flavour; it usually contains 40 or 50 per cent. of alcohol, and, like pulque, possesses certain medicinal properties. Mezcal issoldcheaply. Itis to be found everywhere, and contributes largely to the demoralisation of the native labour- ers, who often drink it to excess. To supply the distilleries at Tequila, a considerable acreage is planted to mezcal agaves. Those chiefly used for the pur- pose belong to a well-marked, narrow- leaved species, which a few years ago received the appropriate and distinctive name A. tequilana.—Queensland A gricul- tural Journal, Jan. 1909, Vol. XXIL., Pt. 1. ARROWROOT-GROWING IN QUEENSLAND. The cultivation of arrowroot in this State dates back to 1864, It was then grown at Oxley Creek by Major A. J. Boyd, who manufactured the commercial article by the primitive process of grating the bulbs and purifying the starch by straining it several times through linen stretched over tubs. The product was then readily sold at Is. per lb. Later on Mr. Boyd sold the bulbs to Mr. Grimes, who also grew arrowroot at Oxley and on the Brisbane River, where he erected the first arrowroot mill installed in the State. The bulbs were sold at £2 10s. per ton; and on the then virgin scrub soils between Oxley Creek and Rocklea, or Rocky Water Holesas the place was then called, the return was enormous. Mr. Grimes grew both the Marauta and the Canna edulis, but the former, owing to the small production of bulbs, was found not to be profitable. ‘ [Marca, 1909. At the present day all the arrowroot manufactured in Queensland is produced in the Albert, Pimpama, and Nerang districts. At Pimpama the Messrs. Lahey had extensive plantations and a well-equipped manufactory. Ornieau, where a considerable quantity of arrow- root is grown, was taken up under the old ‘Sugar and Coffee Regulations,” by Major Boyd, who erected asugar mill and grew cane for several years. He named his plantation ‘‘ Ormeau,” hence the name of the railway station on the South Coast line. A very interesting account of the arrowroot industry, by H L.—presumably Mr. Leahy— appeared in the ‘ Brisbane Courier” of 17th October last, and we reproduce it as showing the rise and progress of the industry since its initiation :— GROWERS AND PRICES. At present the growers are all situated about Yatala, Pimpama, Ormeau, and Nerang, and the principal ones are Messrs. J. Latimer and Sons, Doherty Bros., R. Doherty, Mayes, W. Murtha, Mills, J. Bull, and Mrs. Clarke. The total area under cultivation is about 200 acres, and Messrs. Doherty Bros. and R. Doherty are the largest growers, having between them about 100 acres, while Messrs. Latimer Bros., at Nerang, have 35 acres. The other growers cultivate 10 to 15 acres each of this product. The yield ofthe marketable product ranges from 15 to 30 ewt. per acre, and the total production is about 690,000 lb., or just the same as was estimated by Mr. Samuel Grimes, in an article written by him on arrowroot cultivation in 1888. _The price to the grower varies con- siderably. Two years agoit brought about £10 a ton, but this year the demand has increased, and fully £20a ton has been obtained. The demand has been largely stimulated by the spread of the knowledge that arrowroot is quite equal to starch for most kinds of laundry work, while even at present prices itis only half the cost. As_ its value as starch becomes more widely known, there is little doubt that a market will be developed fora largely increased supply. Taking the figures for last year, we find that 1,284,815 lb. of starch, valued at £17,375, was imported into Queensland, mostly from Victoria, and much of thiscould no doubt be replaced by the cheaper and equally effective arrowroot for all classes of laundry work, except cold starching— that is, in the case of such articles as shirt fronts or collars. Although its use asa starch is by no means new, the knowledge of it has in the past been limited and it is only recently that it MARCH, 1909.1 has come into popular vogue. for years past arrowroot has_ been utilised chiefly for culinary purposes, such as the manu- facture of superior quality biscuits, light cakes, and easily digested foods for invalids. MARANTA AND CANNA. The Queensland arrowroot is really the starch product of a bulb of the Canna tribe of plants—namely, Canna edulis. Thisis mentioned particularly because it differs from Bermuda arrow- root, and cannot be sold in Great Britain as arrowroot without some qualifying term attached, such as ‘‘Queensland arrowroot” or ‘* Australian arrowroot.” How this has come about is rather interesting. When the Drugs and Hood Act was passed by the Imperial Parlia- ment, it was specified that arrowroot is the product of the plant Maranta arundinacec. That is what Bermuda and Mauritius arrowroots are made from; and manufactured arrrowroot from the Canna edulis was then practi- eally unknown in Great Britain. How little actual difference there is between the two is indicated by the following analysis, taking the best Bermuda arrowroot (Maranta arundinacec) at 2s. 6d. per lb., and the Queensland arrowroot (Canna edulis) at 2d. or 3d. per lb, :— Bermuda Queensland Arrowroot. Arrowroot. Moisture... 13:00 to 16°50 17°36 Starch es 82°24. 81°52 Ash *124: 142: Proteids 052 078 Fibre 4:09 to 1:20 “20 The result is, therefore, chemically about the same, particularly in regard to starch, which is the chief constituent. There is a little more moisturein the Canna, and more fibre in the Maranta. Under the microscope the Canna arrow- root shows a more silky texture, and the grains are slightly coarser. The Maranta arundinacee equally well in Queensland with the Canna edulis, and arrowroot-growers have at various times cultivated it. It has been known as white arrowroot (from the colour of the bulbs), while the present article is called purple arrow- root. The reason that Maranta has never become popular here is that it yields only half the quantity of arrow- root given by the Canna, and the growers could get no more for the product; and also because the excess of fibre in the Maranta made the matter of treatment more difficult. METHODS OF CULTIVATION. A visit to some of the arrowroot farms has just been made to ascertain how the grows 237 Hadible Products. industry is progressing, and how itis being conducted. There is a similarity among them all. The rich alluvial pockets along the banks of creeks are the growing grounds. A manufacturing plant, comprising boiler, engine, pump- ing, pulping, and straining machinery is required, which costs about £500. Then there has to be a drying ground, with the requisite frames, and a shed for storage and packing purposes. The bulbs of the Canna are sown in prepared ground from September to December, when the weather is showery, the rows being 6 ft. apart and 4 ft. between the plants, The usual cultiva- tion follows to keep the ground clear of weeds until the plants get tuo big. A field of Canna presents a pretty sight, the broad leaves of dark-green giving a fine impression of richness, and some- times also scarlet flowers are to be seen on the plants. From six to eight months brings the crop to maturity, and a little frost is then beneficial by shrivel- ling up the tops and concentrating the starch in the bulbs, The tops are eut off by means of a cane knife or bill hook, and the bulbs—something like potatoes, but larger—are then dug as required for milling. PROCESS OF MANUFACTURE, The bulbs are carted to the milland shovelled into a root-washer—a trough 10 ft. or 12 ft. long, through which water is continuously flowing, and in which a splindle revolves and works the bulbs up to the end of the trough, There an elevator receives them and carries them up to themill. There they are grated in a grinder, or perforated wooden drum, revolving at great speed, and the pulp passed through to a sieve of perforated metal, clean water all the time falling on the pulp. A beater forces the farina and water through the sieve, while the fibre is discharged on toa dump. The farina from the sieve goes into a revolving copper drum, which has.also perforated sides, and this takes away some more of the impurities, while the farina goes down into a long trough, through which a stream of water is constantly running. The arrowroot settles at the bottom of the trough, and after some hours of washing is dug out and put into tubs, or other troughs, and more clean water with it. _ That is repeated three times, the farina during the last having to pass through asieve of a fine muslin. After that the arrowroot is dug out, placed on calico sheets, and put out on frames to dry. The whole process, from the digging of the bulbs to the drying of the prepared arrowroot, occupies about twenty-four hours. Edible Products. It will easily be seen that it is of little use trying to manufacture arrow- root unless there is a plentiful supply of good clean water. Mr. J, Latimer, who had eight acres under arrowroot at Yatala this year, was working his mill two or three days a week, and pro- ducing about half a ton of arrowroot aday. Todo this, he estimated that 24,000 gallons of water were used in eight hours. The refuse, fibre, and pulp are carted back to the fields for use as manure. After drying, the arrowroot is ready for bagging, and it is put in sacks lined with calico ready for market. Most of the arrowroot is brought to Brisbane by steamers on account of the cheaper freights. By railway from Stapylton to South Brisbane (24 miles) the freight is 8s. per ton, and 2s. 6d. more has to be paid for cartage to business places in the city—a total of 10s. 6d. per ton if by rail. By steamer from Yatala_ the freight is 5s. per ton and Is. 6d. a ton cartage from the wharf to the stores— total, 6s. 6d. By train the cost from Nerang is 12s., andby steamer 8s.;so that the advantage of water carriage will easily be recognised in the case of pro- ducts which leave only a small margin of profit. Mr. T. Doherty, one of the principal growers, remarked that arrowroot gave about the same return as corn or pota- toes, but it wasasurer crop. It would stand flooding that would kill potatoes, and dry weather would not affect it so adversely as it would corn. At the Melbourne Exhibition, Murtha received the gold medal for arrowroot, and J. Latimer the silver medal; and at Karl’s Court Exhibition (London), in 1889, Messrs. J. Latimer and Sons received asilvermedal and diploma for their exhibit of arrowroot. EARLY HISTORY oF ARROWROOT. The name of Mr. Samuel Grimes has long been connected with arrowroot manufacture, and he assisted it along very materially in years past. At the present time, Mr. J. Latimer is prob- ably the grower who has been longest in the business. He related how in 1868 he went to Messrs R. and G. Board’s plantation, Malungmavel, to _ erect some machinery for the sugar-making, and also to put up an arrowroot manu- facturing plant of a primitive type. Messrs. Board had ten acres under arrowroot, and they then got £40 per ton for it. At that time Mr. Grimes was also growing some. In those days the whole of the product went to Mel- bourne. As sugar was then paying very well, Messrs. Board relinquished W. 238 {MarcH, 1909. arrowroot growing, but Messrs. Grimes and Lahey continued with it, and soon afterwards some small growers began to raise the bulb. Since then it has continued to be a small farmer’s crop, largely on account of labour con- ditions making it unremunerative to pay much outside the grower’s family. The 200 acres grown this year will probably produce 250 tons of market- able arrowroot, worth approximately £5,000. There are areas of suitable land with good water available in the district to widely extend the industry should the demand justify it, and no doubt the day will come when much of the starch used in Australia is manu- factured in the same district, from arrowroot, potatoes, maize, and other products which flourish so well there.— Queensland Agricultural Journal, Vol, XXII., Part I, Jan. 1909, TROPICAL FRUITS IN COVENT GARDEN. According to a leading fruit salesman in Covent Garden, ‘‘the demand for rare tropical fruits is increasing.” Not many years ago the Banana, for instance, was a rare fruit in England. To-day the fruits are within the reach of all classes, being retailed in every greengrocer’s shop, as well as in the costermonger’s barrow. Moreover. Bananas are now imported not only in the fresh, but also in the preserved state, as well as in the form of flour. The imports of this fruitin the fresh state have in a few years increased by millions of bunches; at certain seasons special express trains are provided for the speedy and safe conveyance to London of West Indian Bananas arriving at Bristol. A similar story could be told of Pineapples, which are now becoming a popular fruit in England being imported from the Canary Islands, Straits Settlements, West Indies and Natal. The culture of Pineapples in English hot-houses is no longer necessary, although it affords an interesting pursuit to those who can afford it as a luxury. , The principal hindrance to the in- creased importation of tropical fruits lies in the fact that they decay so readily after reaching acertain stage of ripeness. This difficulty is, however, being over- come to some extent by means ot effective cold storage on board ship, and by rapid sea transit. It is to these circumstances that we chiefly owe such recent intro- duction from tropical climes as the Mango(Mangifera Indica), Avocado-pear (Persea gratissima), Grape-fruit, Cheri- moyer (called Custard Apple in Covent Marce, 1909.) Garden), and Passion fruit (Passiflora). So far, the demand for these ‘fancy fruits,” as they are called in the trade, is limited, and the prices charged for them are high. As the fruits, however, become better known and the means of transport more perfect, it is reasonable to suppose that they will become popu- lar, and with a greater demand they could be sold at lower prices. Itis often said that the chief recommendation of most tropical fruits lies in their novelty, Although this may be admitted in some cases, there are striking exceptions. It is true that the taste for certain tropical fruits has to be acquired, but in the case of the Tomato, an acquired taste has been followed by the immense popu- larity of this fruit. It has been said by travellers that the three most delicious fruits in the world are the Pineapple, Cherimoyer, and Mangosteen (Garcinia Mangostana). The Mangosteen is as yet practically unknown in Kurope, but its good qualities may be judged from the opinion of Dr. Abel who said that “of eastern fruits the celebrated Mangosteen is first in beauty and flavour.” Another authority declared that ‘‘the flavour of the Mangosteen partakes of the com- bined taste of the Pineapple and Peach, and other equally good but inexpres- sible qualities.” A peculiarity of this fruitis that a large number may be eaten at once. Therefore, one can under- stand why these are always charged for as extras on hotel menus in Ceylon. Covent Garden, the great horticul- tural market of England, affords a special opportunity of forming an ac- quaintance with tropical fruits which are seldom seen elsewhere in this country. Rare tropical nuts and fruits may also be seen and tasted at Shearn’s Fruit- arian Restaurant in Tottenham Court Road, where numerous dainty dishes are made entirely of fruits. The following sorts have recently been noted in Covent Garden, and it may be of interest to give a few of the particulars concerning these as well as descriptive notes from my own expe- rience in the tropics :— Manco (Mangifera indica),—This ts a medium-sized or large tree; the fruit varies from the size of a plum to that of alarge goose’s egg; very juicy and often of a delicious flavour; it is very popular in the Eastern tropics for desert and for making chutneys. The fruits seen in Covent Garden are usually brought from the Canary Islands, and they are small, They are sold wholesale at from 4s. 6d. to 6s. per dozen, good specimens being retailed occasionally at 2s. to 3s. each. 939 Edible Products. AVOCADO-PEAR (Persea gratissima).— A small evergreen tree, having fruits similar to large green pears, sometimes streaked with red. It isa salad fruit rather than dessert; the pulp is of the consistency of firm butter, and is scooped out with aspoon, being flavoured with vinegar, pepper, and salt. This fruit has recently become popular in America. It is regularly imported to London from the Canary Islands, and finds ready buyers in Covent Garden at 4s, to 6s. a dozen, but good fruits are sometimes pou’ at the price of 2s. to 2s. 6d. each, GRAPE-FRUIT (Citrus decumana var). —A globular fruit resembling a large orange, to which it is allied. It is im- ported in cases of 50 to 100 or more fruits, according to their size, and the fruits are retailed at 6d.to 10d. each. This fruit comes chiefly from Florida, where it is very popular. American residents in London are the principal buyers. ‘‘ Grape-fruit” is an American name, the fruit being a variety of the Pomelo or Shaddock. POMEGRANATE (Pudica granatwin).—A shrub or smalltree, with showy scarlet flowers. The fruits are large and globular, about 3 inches or more in dia- meter, sometimes ofa bright red or orange-yellow in colour. The interior consists of numerous, closely-packed, large seeds, which are coated with an acid, juicy, and astringent pulp. Pome- granates are imported from South Europe andithe Mediterranean, occasion- ally retailed in London at about 6d. to 10d, each or {cheaper. PERSIMMON (Diospyros Kaki).—A small bushy tree of the Ebony family, The fruit is the form of a moderately-sized apple, bright orange-yellow in colour, with ashiny rind. The pulp, yellowish in colour, is ofja peculiar astringent flavour, for which a taste has to be acquired before it canbe enjoyed. The fruit has an attractive appearance, and it travele well. Persimnions are sent to Covent Garden from- South Europe, neatly packed in tissue paper and shavings, in boxes containing about two dozen fruitsin each. The fruit sells at about 8d. to 10d. ‘each. CHERIMOYER OR CUSTARD APPLE (Anona Cherimolia).—A large heart- shaped, dull-green fruit, the rind ‘of which has the appearance of being formed of scales. The interior contains white granular sweet pulp, somewhat resembling custard. Weekly consign- ments arrive in Covent Garden from Madeira during the winter months. The fruits are retailed at about ls. or more each, being sometimes sold in West End Edible Products. 240 shops at double or treble this price. Cherimoyers do not travel well, and a large proportion of every consignment arrives in London in an unsaleable con- dition. PASSION-FRUIT (Passifloria edulis).— The fruit of a pretty climber, of the size of a large Plum, purple when ripe; the interior consists of sweet acid pulp in- termixed with the seed; this, beaten up with a pinch of bicarbonate of soda, forms a delicious drink. When ripe, the vind soon shrivels, giving the fruit an unfavourable appearance; hence it is not suited to the Hnglish market. Trial shipments have been made from Australia which transport well, but the shrivelled appearance of the rind is usually against its sale. In Covent Gar- den the name “ Passion-fruit” is given -to another species of Passiflora, which seems to be the Sweet Cup. SwEET Cur oR WATER LEMON OF JAMAICA (Passifloria laurifolia),—The fruit of this is of the size of a duck’s egg, the rind being smooth and of a_ pale amber colour. It is imported regularly from Madeira, where it is known by the name ‘‘Maracugia.” The fruits are re- tailed in London at 6d. to 8d. each. Both this and the preceding species are some- times known in Covent Garden by the name ‘Granadilla,” a term which is more correctly applied to Passiflora quandrangularis. MONSTERA DELICIOSA.—A very hand- some creeper, with huge leathery, curi- ously perforated leaves. The fruit is like a long, green cone, from 8 to 15 inches Icng; it is pleasantly fragrant when ripe, and partakes of the flavour of Pineapple ; but the small, black hairs attached to the edible portion cause an uncomfortable sensation in the throat. The fruits arrive in Covent Garden from the Canary Islands, and occasionally from Jamaica, and are soldat Is. 6d. to 2s. 6d. each, GUAVA (Psidiuin Guava).—A small tree. The fruit variesin size accord- ing to variety, but usually it is oval and about the size of a medium Pear. It is renowned for making jelly, but is not popular for dessert. Yet the fruit has avrived in London from Ma- deira in increasing quantities during the last few years; itis said to sell at 2s. 6d. to 3s. 6d. a dozen. Brazit Nut (Bertholletia excelsa).— A tall, handsome tree of Brazil. The fruits are globular in shape and dark brown, 4 to 6inches in diameter, with a thick, woody husk; this contains the hard-shelled seed, which are the Brazil Nuts of commerce. They are commonly retailed at 6d. to 8d. a pound, according toquality. These are used at some res- tame instead of suet for making pud- ings. SouarRi Nut or Butter Not (Caryocar nuciferun).—A lofty, handsome tree, with large opposite leaves, native of tropical’ South America. It produces large, dark-brown fruits of the size’ of a child’s head, and similar to the Brazil- nut fruit. It contains about four large, kidney-shaped seeds; these have a red- dish, woody shell, which can only be broken by an axe or similar implement. The seeds are the Butter Nuts of shops; each contains’ a large, white kernel, which has a very pleasant, nutty flavour. The nuts are sold in England at about 3d. or 4d. each. CasHnw Nut (Anacardium occiden- tale.\—The fruit of a moderate-sized spreading tree. It consists of two dis- tinct parts--a much-enlarged. succulent, green receptacle, at the end of which is the hard, brown, kidney-shaped fruit. The latter contains the Nut, which when roasted is very palatable. These Nuts. though scarcely known in = Covent Garden, are imported from India and the West Indies by afew dealers, who find no difficulty in disposing of good samples at 6d. to 8d.a lb. The Nuts will keep in good condition for several years it kept dry. Asample ten years old was exhibited at the recent Colonial ' Fruit,Show at the R. H. S. Hall. GROUND Nut oR MonKEY Not (Ara- chis hypogea).—A small, leguminous annual, which has the peculiar habit of burying its young pods underground, where they develop and ripen; these are forked up when ready for harvest- ing, cleaned, sorted and exported in their small, grey, papery shell. They keep good for a long period, and are generally seen in small lots for sale in greengrocers and fruiterers’ shops, the retail price being about 38d. to 4d. a lb. Licni or Lircut (Nepheliwn Litchi).— A celebrated Chinese fruit borne on a medium-sized tree. The Lichi is usually of the form of a small Plum, with a thin, brittle shell of a reddish colour, covered with wart-like protuberances. It is filled with a sweet, jelly-like, opaque: pulp, and is held in great esteem for dessert and preserves in China. Lichies are Cou ane in London at ls. to Is. 6d. per lb. Loquat (Photinia Japonica).—A small Japanese tree. The fruit resembles a small Apple or Medlar, and is of a sub- acid flavour, It is sometimes imported from South Europe. - 7 - ¢ FOIA it SF NBS as wat Pn a se oe Marcs, 1969.] In addition to the foregoing fruits, there are those which have become standard commodities, such as Oranges, Dates, Figs, &e. Of equatorial or strictly tropical fruits, however, there yet remain unrepresented in Covent Garden @ number which are of excellent quality, and which could not fail to become popular in Europe if they could only be imported in good condition. The celebrated Durian fruit, for instance, is itself ‘‘ worth a journey to the East to enjoy the pleasure of eating it,” in the estimation of so high an authority as Dr. Russell Wallace. Notwithstanding its very offensive odour, the Malays attribute marvellous properties to this fruit, and when it is in season they camp out in families so as to enjoy it. to the full. The following fruits are all of excellent quality, and worth the atten- tion of epicures and dealers in tropical fruits. Dorian (Durio zibethinus).—A gigan- tic, quick-growing, handsome tree, thriv- ing only in moist and hotdistricts. The large oblong fruits, which are covered with formidable spikes, are borne mostly on the stouter branches, each weighing, when ripe, several pounds. The edible portion is the peculiar, fat-like, creamy substance in which the seeds are em- bedded. In spite of its odour, Europeans and others soon acquire a taste for it, often preferring it to all other fruits. Locally, the fruits are sold at the equiva- lent of 1@d. to Is 6d. each. This fruit has probably never been grown in Europe; indeed it may be questioned whether it has been seen there in an edible condition. MANGOSTEEN (Garcinia mangostana).— A medium-sized, slow-growing tree, with large, handsome leaves. The pretty, smooth-skinned fruits are of the size of Apples, perfectly round, and purple when ripe.

Being. deeply anxious for a radical reform in the whole question of so-called Edible Producis ‘indentured labour” in Portuguese African territory, we were most disap- pointed at the results of the meeting, results which were entirely due to lack of judgment on the part of the Chair- man, who seemed unable to realise that the converted audience infront of him, anxious to get home to their dinner or catch a train, wasas nought compared to the opposition who went away, we take it, well satisfied with the results of the meeting. Kar better that the meet- ing had never been held than to refuse— politely, but none the less firmly—under the plea of want of time to allow an amendment to be discussed by the opposition, whose arguments are prob- ably so weak as to rather tend to bene- fit us by being advanced, but which can cause us much trouble by being sup- pressed. As one opponent stated, no practical man wants to waste time talk- ing at the end of a meeting, as the Chair- man proposed, when the resolution had already been passed, and it was too late. People who cannot be inconvenienced by missing their trains should not pretend to interfere in these complicated inter- national labour questions, If they imagine such matters can be settled by two hours’ talking on one side of the question only, they are seriously mis- taken. As a result of this mistaken policy of the Chairman, backed up, it is true, by the majority of the meeting, unsavoury truths about the state of the indentured labour in our Colony of Nels were brought prominently for- ward. We can only hope that some indirect good may come from attention called at the meeting to the Natal scandal, a matter that might probably not have been dragged out so aggressively as it was, in speeches more eloquent, telling, and far less tedious than were some of those devoted to the real object of the meeting. We feel sure that every one present had read the articles and letters pub- lished on the subject, and attended with their minds pretty well made up one way or other, the same as ourselves. We, therefore, were surprised that nearly two hours were devoted to converting thealready converted, whilst We were most anxious to hear what the Opposition had to say. We did not want to be told two or three times over what wealready knew. We went hoping to learn some points from our opponents as to why there is any need to buy San Thome cacao at all until the state of slavery is eradicated to the uttermost end, when our own British Gold Coast - Colony will be producing less ‘‘hammy” and altogether a sweeter and more Edible Products. 348 neutral bean to the tune of 30,000,000 lb. this year, and our total Colonial output amounts at least to 100,000,000 lb. during an average year’s crop. Against this the total consumption in the United Kingdom for 1907 was only 44,500,000 lb. (=19,842 tons) raw cacao. Another question that we hoped to extract infor- mation upon was, why San Thome insists on using labour that at present costs, according to Mr. Nevinson, from £35 to £40 per head—a labour unwilling and home sick, and therefore very in- different whilst alive, and which appa- rently takes the first opportunity that presents itself to die? It cannot al- together be the climate. Can it be that the treatment is not so rosy in reality throughout the Island as a whole as it is reported to be, in one or two cases, on paper? Whatever the reason is, it must bea very strong one. What it is we went to the meeting to find out, but were unable todo so. So we lost much time that we could ill-afford, but worse still, we consider the cause got two nasty knocks that will take it some time to get over. If only the conveners of this meeting had left Mr. William Cadbury and Mr. Joseph Burtt to fight the battle alone, this would not have happened. Everybody at the meeting agreed that these two are strong fighters with right and might (in the shape of the trade boycott) on their side, and this being so what better champions could the cause wish for? Why call public meetings, and run the risk of making our oppo- nents’ weapons still more formidable than they are at present.— Tropical Life, Vol. IV., No. 12, December, 1908. THE FERMENTATION OF CORFEHE. (By Oscar LoEw, Physiologist.) The so-called fermentation of coffee has thus far not been investigated, and has been defined sometimes as an “aleoholic fermentation necessary to remove the saccharine matter.”* “Such saccharine matter, however, should be easily removable by simply washing with water. Upon close examination the writer concluded that the aim of the “fermentation” is the removal ofa slimy stratum firmly adhering to the parchment envelope of the seeds. The removal of this is necessary because the drying of the seed envelope would other- wise be very much retarded, and because a bad flavour may finally be imparted to the seeds by the partial decay of the slimy stratum during the drying process, * Cf. Watt. Dictionary of the Economic Products of India. Calcutta, 1899, vol. 2, p. 476. (Marcu, 1909. The process will be explained by examin- ine ne anatomical structure of the ruit. Just below the skin of the fruit and extending between the enveloped seeds is a fibrous tissue containing sweet juice. This pulp, together with the skin, is easily separated by mechanical means from the seeds. which are enveloped in a hard parchment. Adhering to this parch- ment is astratum of very slimy cells, the slime layer. The preparation of coffee for market requires the following manipulations :— (1) Pulping to secure removal of the skin with the adhering tissue. (2) Fermentation to separate the slimy layer from the parchment envelope, (8) Washing away the loosened slime. (4) Drying the envelope around the seeds, preparing for the necessary brittle- ness for the next operation. (5) Hulling or milling, consisting in the removal of the parchment envelope, with subsequent subjection toa fan to blow away particles of parchment envelope and silver skin. The entire fruit is often called ‘‘cherry” from the similarity of form and colour. The expression ‘‘ pulped coffee” signifies seeds in the parchment envelope with slimy layer. ‘‘Coffee in parchment” means the product after pulping, fer- menting, and drying. The ‘ bean” means the seeds deprived of parchment and silver skin. Fruits of red or yellow colour should be picked for pulping, as only such furnish seeds of the desired bluish-green colour. Green unripened fruit containing a hard pulp and little or no sugar should be excluded, but such fruit cannot he entirely avoided since some unripened seeds will drop off in gathering the ripened ones. The fruits are well moistened with water when passing through the pulper, which easily separates the skin and fibrous layer. Attached to the pulper is a conical sieve (separator) placed ina horizontal position, which retains the fruits which have accidentally escaped pulping, and they are carried back to the pulper.” *It has been proposed to dry the pulp and bring it into commerce as a cheap substitute for coffee. When pressed well to remove the caffein and mixed then with molasses it might serve asa food for hogs. Greshoff holds that the best appli- cation is as a manure and gives the following composition in the air-dry state: Caffein, 1:1; carbohydrates, 23°3; albumin, 7‘6 ; cellulose, 16°) ; water, 14:9; fat, 3°3; ash, 69. i ee ; . ‘ ial Marcu, 1909.] In order to understand the ferment- ation process, it must be remembered that on the surface of all sweet fruits are a great many yeast cells and bacteria. When by the pulping the sweet juice is forced out and spread all over the separated skin, and over the pulped coffee, it is not surprising that these organisms develop rapidly. The sweet juice not only contains sugar but also some nitrogenous and _ mineral matters required for the development of organisms. An examination of the skin witha high magnifying power several hours after pulping shows numerous cells of Saccharomyces, which in form resemble chiefly Saccharomyces ellipsoideus and sometimes also S. apiculatus. Numerous bacteria are also present. Alcoholic fermentation can soon be de- tected by the vinous odour, and the fact that the fermentation produces heat ex- plains why the temperature of such a heap of pulp rises considerably after a time. A heap of nearly 30 centimeters in height showed after sixteen hours a temperature of 41°C. atan air temper- ature of 26°C. Later, acetic acid isformed and the red colour of the skin changed to a brownish one. When the pulped coffee, on the other hand, is examined, a few yeast cells and bacteria are noticed on the slimy stratum after one hour, while after sixteen hours an immense increase has taken place, and not oaly is considerable alcohol formed by the yeast cells but also acetic acid by certain bacteria. Mycoderma and the mycelium of fungi are occasionally seen. Litmus is reddened intensely and the odour of acetic acid readily discernible. At the same time another volatile pro- duct is formed in small quantity, which modifies somewhat the acid odour. The alcoholic fermentation of the sugar adhering to the slimy stratum, as well as the further oxidation of the aleohol to acetic acid, and finally the respiration process carried on with considerable in- tensity by all these organisms, cause a rise of temperature, depending upon the depth of the stratum and thetemperature of the surrounding air. The heaps of pulped coffee are generally 1 to2 feet high, In such heaps the temperature was found after fifteen to sixteen hours to range from 34° to 42° C. at an air temperature of 25° to 29°C. The alcoholic and acetic fermentations proceeding in the heaps of pulped coffee are, however. not the most essential phenomena ; the most important point is that the slimy stratum is separated from 32 249 Edible Products. the parchment envelope. It is by no means dissolved, but merely loses its firm adhesion and is left loosely spread upon the parchment coffee so thatit can easily be washed away by a current of water and the parchment coffee dried. Neither the acetic acid nor the enzyme already present in the slime causes the separation of the slime layer, as tests have shown. Freshly pulped coffee was kept in dilute acetic acid (about 1 per cent,) at 35° to 40° C., and another portion in some water containing a few drops of ether to’ prevent bacterial growth. In both cases the slimy layer was found still firmly at- tached to the parchment after twenty hours. This leaves no other inference but that a peculiar enzyme dissolving the adhesive substance (a carbohydrate ?) be- tween the parchment and the slimy stratum was furnished by the bacterial growth, or, what is less probable, by the yeast cells. The ‘‘fermentation” should not take longer in Porto Rico than fifteen tu twenty hours, while in some sections of Central America, as Guatemala, it must be carried on for two days. Undue prolongation of the ferment- ation must be avoided, as otherwise a brown colouration of the parchment and of the seeds is produced and the seeds further acquire a disagreeable odour— two circumstances which render the pro- duct unfit for the market. After the fermentation and washing the parchment of the coffee is readily dried, either on cement floors exposed to sun and air, or better in rotating eylinders through which warmair passes. At a certain degree of dryness the parch- ment becomes brittle and breaks easily in the milling process, which thus re- moves the parchment envelope and silver skin from the seeds. In fact. the milling must be done while the parchment is still warm. This milling isin many cases done in London, and not in the country where the coffee is produced. Better preser- vation of shape and colour of the bean has been observed, when the latter is protected for atime by the parchment envelope. The cost of transportatior is in this case a little higher, but it does not come into consideration, as from $2 to $3 more has been realized per hundred- weight for eoffee thus treated than for that cured in Central America. In reviewing the so-called ferment- ation of coffee, the conclusion is inevit- able that alcoholic and acetic ferment- Edible Products. ations are not of direct benefit, but only indirectly, inasmuch as heat is thereby produced which supports the action of a body (enzyme) furnished by the bacteria, which dissolves the adhesive substance between parchment envelope and slimy layer.—Philippine Agricul- tural Review, Vol. I., No. 9, September, 1908. eS MANIOC OR CASSAVA. By Epwin B. CoPpELAND. (Concluded from page 24.) _ The best time at which to harvest the roots for starch manufacture ought to be very carefully determined locally wherever the manufacture of starch is an industry. In the Straits Settle- ments the Chinese are said to wait until the roots are eighteen months old, while the European planters harvest their crop in about ten months. In determining the most popular age, various factors must be considered—the weight of roots, their starch contents, and the rental of the land, or its productivity if replanted, being the most important. The weight and the content of starch depend upon the variety grown, the climate and season, and the cultivation. The de- pendence upon variety and season is well shown in the following table repre- senting the yield of five native Jamaica varieties. The 1907 crop had an excep- tionally wet season, Bulletin, Department of Agriculture, Jamaica, 5 (1907) 78, Cassava Trials in 1907. H. Cousins. Of twenty-two varieties, only the five which gave the largest yield of starch in 1907 are copied here :— Starch per acre. 1907. Tubers (tons). % lb.

"4,107 12,682 Black Bunch of Keys 2,388 8,894 Brown Stick 2,384 8,927 Blue Top 5,636 15,818 There were five other varieties in the 1906 crop whose yield of starch when 2 0 {Marcg, 1909. eighteen months old was over five tons per acre. As between twelve and eighteen months, the general result is that tor the sake of greater yield it is decidedly better to leave the plants a year and a half. Conditions in the Phillippines are the same. While the percentage of starch, a scant ten in the roots of 5-month-old plants, reaches its maximum at about ten months, the most rapid growth of the roots is then only well under way. The percentage of starch begins to decrease, at least sometimes, before the plants are twelve months old, but the total amount con- tinues toincrease rapidly, and the slight- ly increased woodiness does not seriously ‘interfere with its extraction. When manioc is raised for food, the roots are dug like potatoes for use as wanted. When it is grown on a large scale, the plants are sometimes pulled by hand from very light soil, but the work is done much more easily by the use of a lifter. Thesimplest lifter is a straight wooden stick, 2 or 3 meters long, strong enough so that it will not break, which is used as a lever. The fulcrum end rests on the ground, and is provided on the underside with an old spade blade or some other flat kody . to prevent its sinking in. Near the ful- crum end is fastened a hook or other grappling device. By lifting the long arm of the lever and shaking the plant is pulled out of the ground reasonably free from adhering soil. If some roots break off they are dug individually. When the field is in sufficiently good cul- tivation to permit ploughing, a furrow is run alongside of each row, making the roots pull up more onellg and with less breaking. The yield of manioc has been the subject of day dreams. Semler, not too positively, cites a New Caledonia plan- tation whose yield in two years ranged from 25 to 250 metric tons of roots per hectare. Reports in German Hast Africa sent to the Experiment Station at Amani range from 2'5 to 225tons. Such reports as these larger ones must be duc to mistake or misunderstanding, or _to computing the yield per hectare from that of a few exceptional plants. Single plants indubitably have produced twenty-five kilograms of roots, and 10,000 such plants on a hectare would yield 250 tons. But such yields do not occur. The yield of some notably good Jamaica varieties has already _ been given. Twenty-five Colombian varieties, grown in Jamaica in 1907 produced 3'1 to 13°3 English tons per acre. From Florida there have been reports of 30 or 40 tons Marcu, 1909. | per acre, and the average near the Lake Mary factory, where the figures should be reliable, has been given as 9 and 10 tons ; but the average cropin the United States is not believed to be more than 5 tons. In Pondicherry 5 metric tons is the maximum crop expected from a hectare of well-manured plants irrigated five or six times a month during the dry season. In Ceylon and Java the yield is expected to be above 25 tons per hectare. A test crop ten months old at Hue was 14:44tons per hectare. There are no data as to the actual yield of any con- siderable acres in the Philippines, but from the unanimous opinion of growers and from our own observations and weighings of apparently representative plants, itis our opinion that 25 tons per hectare is a very low estimate of the yield fairly to be expected from a crop a year o1 upward old. Many analyses showing the starch content of manioc have been published, but it is not worth while to copy them here. Data onthe best Jamaica varie- ties have already been given. The matter of business interestis not the absolute starch content of the roots, but the amount which can be obtained by practical manufacturing methods. This of course depends on how much isin the roots, but to a greater extent still upon the method used in its extraction, and the thoroughness with which it is worth while to extract must be settled locally according to the value of the starch and the cost of producing the roots. For this reason the same methods are by no means to be recommended for all parts of the world. The highest starch con- tent Ihave seen published is 36°5 per cent. ina Colombian variety grown in Jamaica in 1903 and called ‘‘Governor Hemming”; four years later the same valiety contained only 30°17 per cent. By commercially feasible treatment we obtained here more than 31 per cent, of air-dry starch, in one test. STARCH MANUFACTURE. The first step in starch manufacture is always and everywhere the same, the roots are washed clean. If any dirt finds its way into the mill, it will stay with the starch through the whole process of manufacture, and be init at the end. A very little dirt destroys the perfect whiteness of the starch, and only perfectly white starch can be soldat a good price. The washing can be done by hand or in a mechanical washer. Mechanical washing of most roots and in most places is much the cheaper, but the great and irregular size, of manioc roots offers some difficulty. When the 251 Edible Products, roots have been thoroughly washed, it is customary to peel them removing the bark and cortex which contain no starch and atthe same time to get rid of any last particles of dirt. If the roots are kept moist until decay begins the cortex will slip off readily in the hands, but this course is not to be recommended. If the roots are perfectly clean the removal of the bark and cortex is un- necessary, for they contain nothing which discolours or mixes with the starch. : The starch in the roots is contained in the cells of the pith. The starch grains are very minute, decidedly smaller than those of potato starch, and the cells containing them are also smaller. For this reason and because the roots are more woody than the tubers of potato, it is more difficult.to extract the starch completely. The walls must clearly be broken to let the starch escape; the starch in any unbroken cell is lost with the fibrous part of the roots. The walls are broken by decay or by scraping, rasping, or crushing the roots. The practice of letting the roots decay has been in use among the poor Chinese of the Malay States since about 1891 in making a low grade of tapioca, but not in the manufacture of saleable starch, A Dutch writer, de Kruijff (Teysmania, 1906, No. 8), has recently stated that by letting the walls decay it is possible to secure the starch very completely and of as good quality as is obtained by other processes. Anyone adopting this method will wisely try it at first on a very small scale, The old Chinese method in the Straits Settlements, when that district first took a prominent place in the manu- facture of starch and tapioca, was to wash the roots, peel them, wash them again, grind or crush them between rollers, strain out the fibrous part of the pulp with asieve which permitted the starch to pass through with the water, let thestarch settle, draw off the water, and wash until clean and dry. This was all done by hand. In the factories of Europeans steam power is in use and the roots are pulped by scraping. Elaborate machinery for starch man facture has naturally been developed special adaptation to corn and _ potatoes. The first attempts at manioc starch mills on the same scale were made in Florida about a decade ago. The Lake Mary factory. put in potato-starch machinery, and with it was unable to get more than 20 per cent. of the starch from roots containing fully 27 per cent. They have since made improvements— Hdible Products. circumstances and the will of the planter which at least, for the most part, should be used in potato-starch manufacture as well—by which, with cheaper plant and at a lower running cost, they get nearly or quite 25 per cent. The new process is the work of Archbold, who published a brief description of it in the Journal of the Society of Chemical Industry (1903, p. 63-66), The washed roots are scraped and milled. The pulp is then driven upward by a stream of water against a wire-gauze diaphragm, through which the starch and water pass. Instead of having the starch settle in still tanks, the milky mixture of starch and water is piped to near the bottom of a tank which has the form of a large inverted cone, in which the mixture flows up- ward. Asthe cone widens upward the rate of flow decreases until it becomes so slow thatthe starch settles against it; only the dirty water flows off at the top, and the starch is drawn off below. To insure the quality of starch, there is one condition more important than all others—an abundance of clean pure water. The pulp must be thoroughly washed to separate the starch from the waste, and then the starch needs from two to sometimes as many as eight washings. If there is any evident im- purity in the water. the starch may be relied upon to take it up. It is of course expected that the starch will be free from all particles of cellulose or wood ; this is easily managed by the use of a sound fine sieve, whether of cloth or wire. The completeness with which the starch can be extracted depends on how completely all the celisare broken, In the fotato-starch factories and in Florida, the comminuation of the roots is accomplished by a rotating cylinder set with blades with saw-like edges. A cheaper mill can be made by filling a sheet of iron or tin with holes by driving a nail into it, driving it always in the same direction. The sheet is then fastened around a cylinder. I quote from Bulletin 106, Bureau of Chemistry, United States Department of Agriculture, page 28 :—‘‘ A two-horse- power gas engine was used for grinding, the mill consisting of a revolving drum covered with a sheet of roofing tin punc- tured to make a grating surface. Over this a hopper was arranged, the whole resting on a suitable frame. This mill cost, when complete, with shaft, boxings, and pulley, $10, and would grind. one ton of tubers in one and a half hours.” The quality of the work of such a mill depends onthe fineness of the projec- tions and the speed of the rotation. cylinder with fine teeth will not work as fast as one with coarse 252 [MaRcu, 1909. teeth; but it will not use much more power in milling a given weight of roots, and for the sake of greater capacity it has only to be made longer. With such a cylinder whose projections are more than one millimeter high, not more than 24 per cent. out of 381 is likely to be ex- tracted. With a cylinder whose projec- tions are less than 0°5 millimeter high it is as easy to get 3 or 4 per cent. more. In the Philippines the roots can be produced at so low a cost that the use of expensive machinery for the extraction of the last possible percentage of starch would be foolish. The money that would be spentin the purchase and operation of such machinery will give a much larger return in starch if it is spent in producing morerocts. The process of manufacture, as it can most profitably be carried out here, reduces itself to this :— 1. Cleaning the roots perfectly. 2. Milling them on the rough cylinder just described. 3. SCREENING THE PULP.—This is sim- ply and thoroughly done by running it through a trough with sieve bottom of cloth or wire. To make it screen well and quickly, the trough should be shaken and fine jets of water should play upon it. 4, SETTLING.—Concrete tanks will, without doubt, prove most* economical. For fast work in washing they should be shallow. 5. WaASHING.—After the water is run off, preferably by means of cocks in the sides of the tanks, the starch must be washed with clean water and allowed to settle, and this must be repeated until itis perfectly white. To keep the starch from making a hard sediment and not being washed except on the top, each tank should have a stirring paddleor set of paddles which will best be worked by hand. Care must be taken that no dirt can fall or blow into the tanks. 6. DryiIna.—How this is done will depend upon local conditions, but wil usually prove unsafe to rely upon the sun. If adrying house is used, it must be absolutely free from smoke and dust. CoOsT OF PRODUCTION. It would not be without interest, if it were possible, to make a detailed statement in support of theassertion that manioec production in the Philippines is remarkably cheap. But as soon as such statements become really detailed, they cease to have more than a very local value, and fit only the case of the individual whose experiments they re- present. The cost of management and the items chargeable as interest, deterior- ation, and rent depend so entirely upon Marcu, 1909.) that a general statement of them is valueless. Government land suitable for manioc culture is available in most parts of these Islands, and can persumably be leased for 50 centavos per hectare, per annum, or bought at10 pesos per hectare. , Ceara Crepe ordinary to fine.

We publish on this page a most interesting document of instructions to Managers on certain tea and rubber estates in Java, which reaches us through the hands of a prominent Ceylon planter, who, in turn, had it sent to him from London. We are not permitted to publish the name attached ; our correspondent had no authority to do this. He tells us he quite agrees with all the Java authority says as to the ruin of estates by clean weeding ; he is old enough, he adds, to remember planters who said of coffee that short crops came in with clean weeding. Mr. Kelway ‘Bamber (as far as our informant understands him) condemns clean weeding in the fullest.and most comprehensive manner ; and although, to a cer- tain extent, it must be allowed on tea estates to work the tea properly, it is the worst of folly to indulge in it in rubber estates. This Ceylon planter saw quite recently a gang of between 300 and 400 coolies in lines, armed with mamoties, scraping a steep hill sido of a new clearing. The loss of soil resulting from such opera- tions is greater than all the manure that could be applied would ever compensate for, He is trying partial weeding himself ; and where it is properly and reasonably done, he has no hesi- tation at all in saying the growth of rubber is greatly superior to clean-weeded fields, As cer- tain eminent planters—he remarks—make clean weeding a kind of fetish, he has no wish to start a discussion which might drift into personalities; but the opinions we now publish are important, and we have pleasure in giving them full promi- nence and expressing our readiness to publishing anything on the other side, that of the clean- weeders, 36 en —— — - nae =. SSS TO JAVA MANAGERS AND ASSISTANTS, Gentlemen,—I forward for your perusal en- closed extracts from Reports of Mr Kelway Bamber, the well-known Ceylon Expert in Soils and General Tropical Cultivation made on and Estates belonging to the Java Rubber—————OCo. this month, as I feel that his remarks express in a few words so exactly the advantages of asystem which I have urged upon all those working under me for many years with excellent results where they have been followed, whilst where the opposite has been the case the system of keeping un. dulating land or hilly ground clean by ordinary ‘neored’ work with the ‘Parang,’ and similar tools has resulted with just the opposite effects, I maintain, and have always maintained, that the scraping of the soils clear :— (a) Means loss of the best soil within a given amount of years varying in accordance with the depth of the good soil, heaviness of the rainfal) and the frequency with which this treatment is done. (b) Encourages grass weeds such as ‘evreh’, djukoet pait, etc., to the detriment of the better and more succulent class of weeds, (c) Is the most expensive form of upkeep there is, aS cutting all the tops of the Kureh plants just about level with the ground has the same effect on itas pruning has on a Tea bush, e.g. that the growth of the weed is strengthened, whilst far more tops come up than there were before the treatment. If only of those who are in charge of Estates would get firmly into their heads that theappear- ance of an Estate at any given moment—that is, whether it is looking beautifully clean or rather dirty—is aemall matter compared with the ENORMOUS IMPORTANUE OF PRESERVING THE SOIL of same which after all isone’s Capital Asset, loss of which must naturally mean deterioration af the 282 property, diminution of Crops, and depreciation of that Kstate. The first and the first and fore- most point every Manager should keep before him is the retaining of the best part of the soil, for a maximum period, from the time the land is cleared, even if doing so forfeits the compliments ofa V.A. or visitors’ congratulations, upon the cleanliness of the Hstate—which may give at the moment much satisfaction to him, compared with criticisius to the opposite offect. J know of Estates in the close vicinity of where I have lived most of my Java career where the Tea crops are reduced to a minimum, almost entirely because the best part of the soil as long ago been washed down to the Ravines through the fault of former Managers, who thought of nothing except pleasing their V. A. on the ground of having the Estate beauti- fully clean. he result of thisis that prolits are wil and the shares standing at a hopelessly low price, there being practically no soil left to grow the crops which are required to make such profits, If gentlemen will only give themselves the trouble of making a good experiment of the two systems ona fairly targe scate, they will see, Jam sure, the difference and results—within a year —for themselves. ThesystemI advocate is dig- ging or forking out all ‘‘Hureh” ‘‘Casso” and injurious grasses, and leaving the harmless or rather beneficial weeds such as ‘‘Sintrongs’’, ““Djukoet Mingoe”, to grow up fairly plentiful but not to such an extent as to impede in any way the cultivation in question. When these weeds begin to get out of hand, cut them down, but at a couple of inches from the ground, so that THEIR ROOTS REMAIN AND PREVENT DISPLACEMENT OF SOIL when you get the heavy rains, But the plan of taking out systematically and wherever they show themselves the Eureh and grass weeds by means of ‘‘garpee djodjo” (forking out grass weed wherever they appear, as opposed to forking a garden right through) a system which should be at a cheaper cost per Bouw every time that coolies employed for this work go round the Estate until the cost is reduced to a trifle, must be systematically, and at regular intervals, followed. In this way you are constantly decreasing your injurious weeds, and encouraging harmless and beneficial weeds, which in themselves keep the first-named out of the gardens. Once a year or more if necessary and if funds are available the whole of these BENEFICIAL WEEDS SHOULD BE DUG RIGHT IN THE EARTH, BEING SIMPLY TURNED OVER in big clods. After this treatment you will see that the injurious grasses are slill further diminished, and the character of the weeds which come up still further improved, until you get a system which combines the advantages of preserving soil, greenmanuring and thorough culti- vation of soil, which—it is impossible for any one who has given much attention to the results of the different systems to doubt—is entirely to the benefit both of the soil itself, and of the growth and health of the product under cultivation, { will be extremely obliged if all gentlemen to whom this letter is addressed, will The Supplement to the Tropical Agriculiurist RESERVE A CERTAIN ACREAGE FOR A THOROUGH AND SYSTEMATIC TRIAL of above ; whilst, if they wish it, they might try the results of the other system of keeping the gardens clean by ordinary weeding (ngored) which is still the most prevalent one, on most Kastern Estates in the Preanger., And I will be extremely obliged, if they will keep an exact record of the frequency with which the dif- ferent kinds of treatments to the grounds are given giving cost of same each time and general results at the end of the year, both as regards the appearance of the soil, and growth and general healthiness of the trees and bushes, being cultivated. Such informa- tions orconclusions I am pleased to hold at the disposal cfany of the gentlemen working on Kstates [ am connected with, and also to hear their opinions upon what L have written above. in my opinion the question of the best form of upkeep in the long run for our Java soils, on steep or even undulating land, is far and away the most important one which the would-be suc- cessful planter of the future has to decide upon. One has only to go through old hilly gardens on Estates in the Preanger, where the Coffee and Kina gardens were for years and yearskept clean by the ordinary ngored system, and where only with the greatest assistance and heavy cultiva- tion, can even a strong product like the tea bush be got to give a fair production, and then to go into a bit of unopened forest, joining same gardens, and with exactly the same lie of land and originally the same soil, to realise what a cruel destruction of property and loss of Share- holders’ money has been effected by this, IN MY OPINION, MOST DAMNABLE OF SYSTEMS by which such estates have been kept beautifully clean in the past to the satisfaction of visiting agents but at a cost of the value of the Share- holders asset. The same results can be seen on very many of the steeper Tea Estates in Mas- keliya, Dikoyaand other steep districts of Ceylon. Hoping those to whom this is addressed will give this matter their close and earnest atten- tion.—I am, Gentlemen, yours faithfully, &c. MESSRS. NicMEEKIN & CO.’S ANNUAL TEA REPORT. Messrs. McMeekin & Co.’s annual report on the tea trade is usually the last to reach us from London ; but itinvariably more than makes up for the lateness of its appearance by the comprehensiveness of its scope and the novelty of its contents. Points of very immediate interest to the tea trade are carefully investi- gated and presented by Messrs. McMeekin, which as arule are ignored by the majority of tea firms in their annual reports. Following this will be found the full text of Messrs. McMeekin’s deliverance on the tea trade of 1908, which we are sure, all our readers will consider well worth reproduction in the 7.A. The report deals with the position of the industry in all pro- ducing countriesaud it will be noticed that Messrs McMeekin’s remarks on Java tea bear out what we stated in alluding to the official statistics of tea production in Java we published last month. Java teas, it is pointed out, have made more and Magazine uf the Ceylon Agricultural Society. progress within the year than those of any other growth. The trade in London, itis true, has made very little progress ; but the teas are laid down so cheaply at the outports that they now form a considerable proportion of the trading in certain centres, thus seriously restricting the possibilities of business in other growths. Deal- ing with the ‘‘ Purity of Tea,” the report subse- quently states that ‘‘ the only growth showing a general improvement is that of Java.” The prevalence of ‘‘ stalks” in Indian and Ceylon ‘eas has, we are informed, caused much com- plaint from country and foreign buyers. Java Teas being, so far, much freer from anything of the kind, have frequently received a preference in consequence. This isa very clear and definite indication of one direction in which British pro- ducers are being beaten by the Dutch Colony. The fault complained of can be remedied and all planters both in Ceylon and India ought to make ita point to see that’ stalky” tea isnot in future placed on the market. With regard to future prospects Messrs. McMeekin regard as the gravest danger tothe industry a large yield from India during 1909, In addition to the report we reproduce else- where, Messrs McMeekin publish a table showing tea statistics for six calendar years and a chart with a statement showing the alterations in the relative proportions of different growths of Tea consumed during 22 years ended 31st December, 1908, the variations in the London average prices for Indian teas, and the changes in rate of Duty. TEA IN 1908. (Messrs, McMeehin & Co.’s Review.) The reports upon the heavy lines of trade of all kinds during the year are generally unsatisfac- tory, and Tea has, to a certain extent, shared in the bad results. The financial convulsion which shook New York in November, 1907, and dis- turbed the money markets of the world, had prolonged after-effects upon nearly every im- portant description of business, and the fact that Tea was not more unfavourably influenced is strong testimony to the sound and general position of the trade. PRODUCERS. A remarkable change came over the character of the demand during the year, and the common- est grades, which for a long time had been kept at a high level of price as compared with those considered to be worth intrinsically much more money, were in lessened demand. Prices of the former consequently fell, slowly but surely, throughout the first eleven months of the year. Coincident with the neglect of the common grades there came an improved demand for better qualities and a widening range of prices, The averages of prices for both Indian and Ceylon Teas showed some decline over the high level of the previous year, but itis probable that the year’s working was more generally satis- factory to the whole body of producers. The phenomenal profits made by Bheel states from enormous out-turns of low grade stuff will not be s0 conspicuous as they wore, but, on the other hand, more encouragement will be given to those 288 producing Teas of good quality. The turning fromthe demand for mere lowness of price to a requirement for quality is a highly satisfactory feature that should receive every encouragement. The estimated value of the debentures and shares of 170 Tea producing companies repre- sentative of India and Ceylon was at Ist November, 1908, £20,000,000 as against £21,600,000 twelve months earlier, Having in view that an average fall of approximately % of a penny per pound was recorded on the total yields, itis surprising that the capital difference was not greater, looking to the reduced dividend- paying power. The shares, however, are gene- rally firmly held by permanent investors, DistRIBUTORS. Following a succession of difficult years, that just gone has been one of the worst on record for those who try to make a living out of mer- chant business in tea, The large wholesale dealers, although working on lower values and a lower Bank rate, have again had to face serious losses from depreciation in stock values, the long continued decline in the lower grades rendering profitable business impossible, The smaller country dealers and the retailers have been faced with the competition of the multiple- shop concerns and it has frequently been of an exceedingly unfair character. Gross misrepre- sentation in the way of lavish advertising as to quality and value is very hard to deal with, but here and there independent traders have made a good stand for the old-fashioned honest methods of describing goods. The failures among retail grocers have for the year been unusually numerous, and the wholesale trade has suffered accordingly. Even the multiple-shop companies, although several of them have made numerous additions to the number of their branches and in some cases added seriously to their working costs, have not all been able to maintain their previous rates of dividend. CONSUMERS. The general lack of prosperity throughout the Kingdom and the large percentage of unemploy- ment known to exist in many districts had little obvious eifect upon the consumption of Tea, The quantity taken actually showed an increase on the previous year of atout 14 million lb. and was again the highest cn record. Allowing, how- ever, for the usual natural increase in the popu- lation, a small Cecline in the quantity consumed per person is shown, In the matter of consumption Tea compares favourably with most of the large lines of goods figuring in the Board of Trade returns and appar- ently itis likely to be one of the last items to be prejudicially affected by adverse industrial conditions. Inpran TEA, Owing to the continued increase in direct trading with India, importations into London again showed a decline on the previous year. ‘fhe offerings in auctions there, were, however considerably heavier, but the difference is explained by the reduced extent of selling forced on the producers in December, 1907, in consequence of ths abnormal financial position then existing. In the earlier months of the New Season the demand in Calcutta for several of the large direct outlets was not so strong as in 1907, and conse. quently more tea in proportion fo the total yield Weg 284 shipped to London (about 8,600,000 lb. increase on the pre- vious season’s figures were received there within the old year). Tbe demand improved towards the close of the year, doubtless in consequence of the considerably lower range of prices established in September and October. The quantities offered in the Calcutta auctions from the com- mencement of the New Season till the close of the year were about 2,000,000 Ib, Jess than in 1907. The total production of the whole of India for 197 was reported as 248,000,(00 lb., or an increase of 7,0uu,000 lb, over the very large total of 1906. It is impossible at present to estimate closely what the figure for 1908 will actually result iv, but in all probability the increase will be abcut 5,000,000 ib, giving a total of 256,060,000 Jb. The recorded exports from India in 1907 were 228,000,000 lb., and it is considered that a serious discrepancy exists in the returns of yield, as it is thought improbable that the internal consumption of India would equal 20,000,000 Ib. The principal develop- ment in production has occurred in Assam, where a more favourable position as to labour is influencing yields. It is fortunate for all concerned in the business that the weather conditions were somewhat adverse, and that, therefore, the very much larger yield whichat one time was expected was not harvested. Cryton TEA, Although further Teais now to a moderate extent being planted in Ceylon, it may safely be assumed that the planting during say four or tive years back was mostly done inrubber. As rouch of the rubber was actually planted among the existing Tea bushes (a system not calculated to conduce to the rapid and successful growth of either product) the development of the rubber trees was bound gradually to tell upon the Tea bushes and ultimately to render their continued culture an impossibility, There is little doubt that the influence of rubber on Tea yields is now beginning to be felt, and that it will soon show itself more definitely, while an increased yield from new Tea planting is still somewhat remote. It may be assumed that the satisfactory prices ruling for Ceylon Teas led to as free plucking as possible; but, notwithstanding that, the total crop for 1908 showed a decline on the 1907 figures of about 2,000,000 lb. As other countries took, in the aggregate, about as much asin the pre- vious year, the deficiency in yield necessarily came off the shipments sent to Great Britain. The shortcoming made room for part of the excess from India and materially helped to steady aud enhance the London market for Ceylon growths. The Home Trade consumption of Ceylon Tea was a record for quantity within the year, viz.. 92,960,000 lb, but in 1900 the igure approached closely to that, being 92,470,000 lb. The share of the total was, however, in the latter year 37 per cent, while in 19(8 it was only 333 per cent. {ft had, however, in the interim been down to 30% per cent. Thereturns to Ceylon producers during the year have apparently been scarcely s0 favourable, onthe average, as those made upon Indian growths. The ratios of prices to those of 1907 (taking Colombo and London mar- kets together, as compared with Calcutta and London markets) were less favourable; there was areduced instead of an enhanced total crop and the high cost of rice was more severely felt than in India. Java TEA, These teas have made more progress within the year than those of any other growth. ‘The total quantity exported from Java within the 12 months ended 30th June, 1908, was 32,792,000 1b against 24,950,000 1b in’ the corresponding previous 1: months. They have gained also in the way of improved quality and in increased consumption in all the larger outlets, viz. Holland, Great Britain and Ireland, Russia, Australia aud Hersia. The trade in those through London has made but little progress on the average of re- cent years, but they are so cheaply laid down at the out- ports baat fuey Bow fm a Gensiderable proportion of the The Supplement to the Tropical griculturist trading incertain centres, thus seriously restricting thid possibilities of businessin other growths. It will be seen trom the statistics that the British home consumption showed an increase ot nearly 50 per cent. in five years, ‘The reports of marvellously cheap labour, unusually rich soil, heavy yields and consequent low costs of production have attracted attention to the desirablity of the island as a tield for investment in tea growing, and names hitherto identi- tied with tea production in British dependencies only are now becoming associated with Java production. This may be in individual self-defence, but any large development in that island cannot fail to affect prejudicially India and Ceylon, and may lead to a recurrence of the outcry for protection for a British industry, formerly so frequently raised against China tea. CHINA TEA. Notwithstanding the advertising and the Jarge amount of press publicity it has received, China ‘ea has fallen back somewhat in British Home Trade use within the year. ‘The considerable increase, relatively speaking, in the imports has only led to a piling up of unsale- able stocks of such a low character that while com- plying with the Government standard of chemical purity, they would not be admitted to the United States of America or Canada, where a more detinite restriction is placed upon what may be sent into consumption. Those importations include a considerable increase in green teas, a class that is almost wholly taken for export. They probably came to London because of temporary derange- ments at other points, and, judging from the relatively high re-exports of China tea, a considerable proportion of the increased arrivals in that class has passed out of the stock, leaving an accumulation consisting chiefly of China siftings that can only be worked off very slowly in small percentages of the cheaper blends retailed in the home trade. Although the business of importing China teas to London has now been,reduced to a very small compass, its volume during the year was sufficient to cause serious em- barrassment to some of those engaged in the business. Owing to high costs and bad realisations the results were disastrous, and it is reported that considerable losses were made upon teas sent direct from China to the other markets that take larger quantities. Those responsible for the modern efforts to boom good China tea would probably carry with them the respect and goodwill of the producers of other growths, and of the dis- tributive dealers also, were they less disingennous in use made ofabnormal statistics. It can do no goodia the long run to give publicity to misleading figures, JAPAN AND Formosa TRA. Vhe latest official statistics issued by the Department of Finance in Tokyo show that the yield of lea in Japan during 1906 from 122,500 acres was 58,260,(001b being a decline since 1897 of 2),000 acres and 12,000,000 1b. The value of the exported quantity was stated to be £1,036 000, he yield in Formosa during 1906 was 15,168,000 lb., ur a decline of 9,060,000 1b, since 1878, The United States of America took a very large proportion of all the quantities exported from both places, ForREIGN TRADE. The re-exports from the United Kingdom have again shown a decided falling off, and are back to about the level current prior to 1906, With the exception of a trifling increase in Sep- tember, the decline was continuous during the first 10 months of the year, but in November and December there were gains amounting to nearly 2,900,100 lb., doubtless arising from the lower scale of prices ruling in London. With the excep- tion of Canada, Indian Tea lost ground in allthe principal outlets. Ceylon, while again losing heavily to Russia and in the general export trade, made headway in business with the United States of America, Canada and European coun- tries other than Russia. The loss of trade in Tea between London and Russia is directly attributable to the policy of retaliation pursued by the latter because of the exclusion of Rus- sian Sugars from the English market by the Brussels Convention. Although the barrier has now been removed, the trade does not appear to be returning, except in a casual manper, and Magazine of the Ceylon Agricultural Society. Calcutta and Colombo taken together have not, any more than London, gained during the year in their tracing with the rest of the world, as compared with 1907. Statistics areas yet in- complete, but it appears as if Russia would take about 2 million pounds less; Australasia is taking about 4 million pounds less ; Canada and the United States of America together take an increase of 2% million pounds, while there is a general increase in places not specially named of about 25 million pounds, SuHips’ Srores, The quantity of Tea absorbed for the use of passengers and ships’ crews has increased in proportion to the Jarge development of tonnage afloat in merchant and Government vessels, but it is unfortunate that so little attempt is yet made to supply tea better in quality and in methods of infusion for the useof those who ‘‘go down to the sea in ships.” Pcuriry or TEA, There was a considerable increase in the number of tea samples analysed by authority of the Commissioners of Customs during the last completed Customs’ year, which doubtless arose from the free importation of China tea of at least questionable purity. Only 33 packages were condemned as unfit for food, while 2,070 were refused admission for Home Consumption. The percentage is very small relative ‘to the whole importation and probably a large portion of the rejected teas consisted of packages damaged in transit. The general character of all tea arriving from abroad does not tend to improve, and it would appear that the same amount of care as for- metly is not exercised in the preparation. The only growth showing a general improvement is that of Java. The prevalence of ** stalks” in Indian and Ceylon teas has caused much complaint from country and foreign buyers, and Java teas being, so far, much freer trom anything of the kind, have frequently received a pre- ference in consequence, Tue Tra Dury. Fortunately for the trade, there was about a minimum of disturbance of regular trading conditions arising from anticipation of Budget possibilities, and it is to be hoped that 1909 will be allowed to pass in an equally placid way. Unfortunately, attempts are being made by professional scaremongers to work up an agitation about a possible increase of auty, but they are unlikely to attract serious attention. PRosPEcts, The New Year started with a stock on hand in all the bonded warehouses of the United King- dom of 128,393,000 lb., against 124,712,000 Ib. at the end of 1907. The difference may be taken as roughly representing the dead-weight of almost unsaleable China sorts now lying in London. Uf the stock, however, probably somewhere about 5,000,000 Ib. more than at the same time last year are held by the buyers and not by the im- orters. The moderate prices ruling in November ed to free buying for forward requirements, and itis known that some prominent coucerns. gan now stay out of the market for months, 285 They are unlikely to pay the recently made ad- vance on lower grade teas until their cheaper stotks are exhausted. Much of the buying in December was not for immediate requirements but merely to guard against the risk of another seriousadvance in tea for price. A rise actually resulted, but, as it did not come from an actual demand for immediate consumption, it will be difficult to maintain. Should the sellers of tea attempt to regulate the weekly offerings, it will be necessary to take into account the surplus over the quantity at the same time in last year, which has passed into the stocks of dealers and blenders. Although 1909 is starting at a more moderate level of price and with better general financial conditions, there are some factors in the future that may be viewed with concern. China tea can be dismissed as a negligible quantity ; Java may show further development ; Ceylon looks like being stationary or even retrograde in yield, but India is still very far from having reached a maximum possible, without making any allowance for newareas coming into bearing, Given generally favourable weather conditions, with the full labour forces now on the majority of estates everywhere, there is the possibility ofa large increase in production at any time, With the home consumption practically stan- ding still and the foreign trade taken all round not progressive,a large yield would be disastrous. There is hope that the lower prices may stimu- late consumrz tion and that possibly the foreign trade of 1909 may expand, because it would ap- pear asif part of the large export business done in 1907 was because of an over-estimation of requirements, leading to a corresponding reduc- tion in requirements during 1908.—McM&rxkin & Co., 10 & 11, Lime Street, E.C,, London, 19th January, 1909, JAPANESE CAMPHOR. In its December issue the “Toyo Yakuho” of Yokohama refers to the Japanese camphor- agency recently acquired by the Mitsui Com- pany. Owing to the fact that Japanese camphor had to face the powerful competition of the cheaper Chinese and synthetic camphor, the company, it states, resolved to obtain absolute control of the business, and to place the staple on the foreign market in the same way as ordi- nary merchandise, without being subject to Government control. Last August the European market heavily declined, and the Formosan monopoly authorities were filled with dismay, The Mitsui Company, quick to seize the oppor- tunity, lost no time in persuading the authori- ties that the present system of working the monopoly was very inconvenient, as it impeded the taking of prompt action to meet circumstan- ces. By the present arrangement the Minister of Finance agrees to relegate to the Formosan Government the right to dictate the price of camphor abroad, the Formosan Government in turn being authorised to place the matter in the hands of the London and New York agents of the monopoly. These ofticials are thus enabled to lower or raise the price according to their own judgment, and they are now transactin business on these lines in London and New York.—Chemist and Druggist, Jan, 16, ; 286 SEYCHELLES CINNAMON OIL INDUSTRY. The possibility of the profitable establish- ment of an essential oil industry in the Sey- chelles Islands has long been under experimen- tal consideration, and about two years ago the idea was first put into operation on a commercial scale, when a modern factory, provided with a boiler and a still of 4,000 litres capacity, was erected. In 1906 work was started by the dis- tillation of citronella and lemon grass; but owing to the late fall in price of the oils obtained from these twce grasses, 16 was decided in 1907 to make cinnamon oil the chief product of the factory for the present. The cinnamon grown in the Sey- chelles is the same variety as that cultivated in Ceylon. Oilis yielded by the roots, the bark, and the leaves of this plant, but from the bark is the most valuable of the three products. The trees are cut down periodically, and the bark from which the oil is distilled is obtained from the young shoots arising from the stumps. These shoots are available for the purpose in about two years. It is not only the young shoots, however, from which the bark is obtained yielding the cinnamon oil. This is contained in the same proportion by the bark from older trees, and tall trees about 1 ft. in diameter are said to yield as much as 100lb. of dry bark when cut down. the average tree, however, coes not give more than about 20lb. of dry bark. This contains from 9 to 94 per cent of cinnamon oil.

ARTIFICIAL CAMPHOR,—It is reported from France that a new company, known as the Société le Camphre, of 65, Boulevard de Strasbourg, Paris, is to acquire various patents for the production of synthetic camphor, including those of MM. Dubose and Behal. A factory has been secured at Bonniéres, and work isto be ‘‘ commenced in the course of afew months.” The old story is circulated that the plan will be capable of producing three to six tons of artificial camphor per day !|—C. & D., Aug. 31, 1907. : Since the above paragraph was. written, facts have transpired which show that the Société le Camphre has fallen upon evil times, the company having practically exhausted its capital of 7,100,000f. (284,0C0/.), while the pro- duction has been relatively unimportant. This much we gather from lengthy reports on the condition of the company which have been pub- lished in the French financial Press. Although the company was formed in February 1907, no rofit-and-loss account has been issued, but a statement of accounts to June 30, 1908, shows that a sum of 4,169,732f. has been expended on the purchase of patents, and that a further 2,300,9C0f, has been laid out in land, buildings, etc. On June 30, 1908, there was 521,070f. at the disposal of the company, while the Nabilities The Supplement to the Tropical Agriculturist. were 270,497f., leaving a balance of 250,573f., which was insuflicient to meet working-expenses, so that a fresh issue of capital is necessary. It appears that ‘Loe Camphre’ was an afiiliated undertaking of the Société!’ Oyonnithe, which had been able to secure the patents for the manu- facture of synthetic camphor, and they in turn formed or caused to be formed another company to which they sold the patents. Subsequently the shares were ‘boomed,’ and the interest of the public was excited to such an extent that many shares were disposed of by the promoters at more than 100 per cent premium. It is not known what proportion of these gains accrued to ‘?Oyonnithe,’ but on December 31, 1907, this company did not possess a single share of the affiliated company, showing that'the confidence inspired in the new company was not very great. Time has proved the wisdom of ‘ l’Oyonnithe,’ as the 100f. shares of ‘Le Camphre’ are now worth 36f. only. The meeting of shareholders on December 31 was stormy, considering that many of them had purchased shares at double the par value. The present board of directors were only able to hold on to their office by the votes of absent shareholders. Aggrieved share- holders pointed out that the company had been stating that the daily production of synthetic camphor was 200 kilos., whereas it appears the company has only produced 2,500 kilos. since its formation. Professor Behal declares he has not received a penny for the sale of his patents, though he was also promised a bonus of 25c. per kilo. on the manufacture.—Chemist & Drug- gist, Jan. 16. RUBBER IN 1908: IN GERMANY. Market Rerort or WattHer & LUHMANN, Rosser BROKERS. AsiA AND AustRALIA.—The production of the Ceylon and Straits commodities has enormously increased, it has risen from 1,400 to 2,500 tons. These commodities, which are prepared with great care and much experience, have doubtless great prospects. Germany already consumes fair quantites of same, however, the consign- ments offered here have been up to the present still unimportant. London offers, however, al- ways lower than Ceylon itself. The import of this fine Rubber is strongly to be recom- mended. From Borneo arrived shipments of fair amounts, principally Gelotong. The increase is probably on account of a new, important consumer. 1 a.—Borneo becomes from year to year worse and isonly slightly better than quality. No. 2a. From Sumatra and Java very fine lots have arrived, in this quality a great deal can be done. The quality of Penang has slightly declined. From Rangoon and Tonkin’ only small shipments have arrived. New Guinea and New Caledonia arrived only insignificant quan- ’ tities and besides mostly wa foreign countries. Finally we refer still to the enormous deve- lopments which have taken place in respect to the demand in Germany, with its over 100 factories it has established itself at the head of all European countries. We trust that the time is not far distant when the German dex mand can be satisfied on the German market, and, Magazine of the Ceylon Agricultural Society. 287 PRODUCTION OF HERVA MATE IN’ BRAZIL. ‘* PARAGUAYAN TEA.” H.M. Legation in Brazil has forwarded the following memorandum on the production of herva maté in Brazil. It appears that this article took the third place in Brazilian exports in 1906, and fifth place in 1907, the value of the export each year being nearly 2,000,002. :— ‘‘*Tlex Paraguayersis’ or Paraguayan tea, known also as ‘ Missionaries’ tea’ and ‘ Jesuits’ tea,’ is to be found wild in immense quantities in the Brazilian States of Rio Grande do Sul, Santa Catharina, Paranda, Matto Grosso, Sio Faulo, Goyaz and Minas Geraes; but more particularly in Parana. It was first discovered by the early missionaries, who found it in use among thenatives of Paraguay, to which country it is also indigenous, It is met with generally in the form ofa tree ransing from 9 to 18 feet in height, there being three varieties of the species known, viz., the ‘latifolia’ with broad leaves, the ‘longifolia’ with long leaves, aud the ‘aneustifolia’ with small leaves, tho last of these being the most appreciated. METHOD oF HARVESTING. It is gathered between the months of April and September, the leaves being considered more mature for the purpose in June and August, and the trees are allowed from four to five years to recover from the effects of a very rough harvest. The branches are broken off and the leaves are withered over a smokeless bonfire, to prevent them from turuing black, and they are further submitted to a primitive pro- cess of ‘curing’ later. MAKING THE Brew. “The original method of consuming maté, and the manner still in vogue in South American countries, is to pour hot water on the top. of the leaves and sip through a tube—the same leaves serving for innumerable brews if they are not allowed to cool. Itis found, however, to give a very good result when prepared like other teas, and, in comparison with the latter, is said to be much more digestible and less harmful to the nerves. It is further stated by writers on the subject to be a stimulant and tonic, its qualities in these respects having been very marked indeed during the Paraguayan war, at which time soldiers wers found to be able to endure the greatest hardships and go for days without food if provided with mate, “The French Consular Agent in Curityba, some time back, tried to bring herva maté before the notice of his Government. for tiv use of the French colonial army, he being persuaded that it would prove a preventative against abuse of alcohol and tropical diseases. To support his arguments he stated that a German military- medical council had recommended its substitu- tion for ordinary tea generally among the German troops. This may account for the fact that maté is beginning to find its way now into Germany, and even more go into Italy, though the imports into both these countries at present 4 are very insignificant. [t is also becoming known in france and Portugal, whilst the amount sent to England has so far scarcely attained the proportions of a sample. Tue NAaTuRAL SuPPLY of the Southern Brazilian forests is reputed to be inexhaustible, and presumably could at any time be largely increased by planting and culti- vation if there were greater demands for it. In the meantime the exports are considerable to Argentina, Uruguay and Chile, with occasional shipments to Paraguay also, though none what- ever is exported to any of the other countries in South America. ‘‘Maté of course is considerably cheaper in this part of the world than are eastern teas, and those by whom the taste for it has already been acquired are loud in declaring it to be whole- some and refreshing and to be possessed of innumerable medicinal virtues. The maté which is shipped from Rio de Janeiro and the other important ports of Brazilis usually ‘in transit,’ the natural ports for direct shipments being the little-known places, such as Paranagua, Antouina, Sao Francisco, Porto Murtinho and Porto Alegre. The increase in the export from Porto Alegre in the last few years has been very remarkable. Inthe year 1902 only 11 tons were shipped, while in 1906 the shipments had in- creased to 11,000 tons, an advance which, while enormous, has at the same time been gradual and has since been maintained, “The following statistics show roughly the in- crease in the foreign exports of maté from Brazil” :— Toy To To To Argentina Uruguay Chile Exports Tons Tons Tons Tons 1902 31,000 10,000 1,000 42,0u0 1903 29,000 5,100 3,000 37,000 1904 32,000 10,000 2,000 44,000 1905 30,000 10,000 1,000 41,000 1906 43,000 18,0 0 2,000 63,000 —Board of Trade Journal, Dec, 31. SHAPING YOUNG PARA RUBBER TREES. Mr Walter Towgood writes as follows :—It is still an open question whether it is advisable to interfere with nature by forcing young rubber trees to throw out branches. Almost all culti- vated trees are pruned and shaped according to the requirements of the agriculturist and in some cases a tree’s natural habit is entirely altered, as for instance, in tea and coffee, The former of these is, however grown for its leaf and the latter for its fruit, but in Para rubber we have to deal with the products of the bark and therefore the shaping of the stems. Hitherto attempts have been made to force rubber trees to branch by thumbnail pruning or topping, but this has not been attended with success, as the upward growth of the tree being stopped, the place of the main stem is taken not by true branches, but by suckers which are very liable to split off and in dcing so the stem itself is also frequently split, thereby seriously damaging the tree. Moreover, the tree once having been headed back, the tapping height of 288 the stem is fixed forall time. T have recantly found that rubber trees can be forced to throw out true branches without interfering with their upward growth. It is then only necessary to prune off superfluous branches in order to shape the tree in any desired form; to accomplish this all that is necessary is to cut off all the leaves, leaving the stalks attached to the stem, these will dry and fall off ina few days and the treo will throw out branches from each node. Para rubber being a deciduous tree, this re- moval of the leaves is, after all, merely a fore- stalment of nature and should therefore be done at the season when the older trees shed their leaves. It is also best to choose the time when the topmost shoot has matured and before a fresh shoot has commenced to grow. Great care must be taken not to injure the bud and thereby interfere with the upward growth of the tree. The above method should only be tried on a very smal! scale to begin with, until it has been proved a success.— Malay Mail, Jan. 25. RUBBER IN BOLIVIA. The following extracts from a Broker’s Cir- cular, (December 30th) give some interesting information in reference to rubber yield, &c., in Bolivia :-— “Tae GALVEZ Rupper Estates, Ltp.” This Company was registered in 1907, whena prospectus was issued for private subscription only. Capital £150,000 of which £135,000 has been issued in £1 shares all fully paid. The largest. shareholders are Sir George Newnes, Bart., M.P., his family and friends, The Chair- man of the Company is Mr. Frank Newnes, M.P., and the Harmsworth family also of news- paper fame are also interested. We extract the following from the prospectus :— ‘¢ This Company has been formed in order to acquire the Galvez Rubber Estates, a well- known fine Para rubber-producing property in Bolivia, and consisting of the properties here- after mentioned. It is estimated to extend over an area of nearly million acres, and is situated in the province of Canpolican, district of La Paz, near the Beni River, Bolivia. “Mr Pharaoh, who is well known in America as an expert in Rubber Forests, and who has worked a portion of the concessions, has certi- fied toat least 300,000 trees (Hevea brasiliensis), Taking a minimum yield of only 4 lb. per tree, this would give areturn of 1,200,000 lb. rubber per annum. Mr Pharaoh states that 6 lb. per tree is a conservative estimate. 150,000 trees opened up and ready for tapping should pro- duce 600,000 Ib. of rubber, which at say 5s. the present price, would realise £150,000 per annum gross. ‘The business has been a going con- cern for the rast six years. The recent owner, Senor Mariano Galvez, of Arequipa, Peru, through lack of capital, has for some years past confined himself to the development The Supplement to the Tropical Agriculturist of only a small part of the estate, which he states has yielded rubber yearly valued at from £20,000 to £30,000 gross. The output for 1905, em- ploying only 100 pickers, amounted to 79,000 Ib. and for a few months in 1906, employing 200 men, 66,000 1b. Inthe year 1902, Mr Pharaoh worked the property during a period of eight months. He had only 200 pickers, and they collected 120,000 lb of rubber from only a small portion of the property, and which atthe pre- sent price of rubber would sell for £30,000, ‘ Kstimating the all-round sale price of rub- ber at 5s per |b and the cost of production at 2s per lb, the total yield of 300,000 trees at 4 lb, per tree would equal 1,200,000 1b and would pro- duce a profit of about £180,000 per annum. ‘Taking asa basis the production available from only 15°,000 trees, this would give the fullowing results :~ 600,000 1b. rubber at 5s. perlb £150,000 600,000 re at cost of 2s.perlb, 60,000 Leaving an estimated nett pro- fit per annum of £90,000 ‘‘ Last year, subsequent to the formation of the Company, as you will remember, there was a financial panic in the United States of America, which are the largest buyers in the world of rubber. As the result of this the enormous factories there were closed, and the price of rubber fell from over 8s to 3s perlb. With a resumption in the United States of the demand, the price has gradually risen until now it 1s again over 5s, with every prospect of a continuance of at least this price. The es- timate given ot production naturally does not apply to the first year, during which the busi- ness had to be thoroughly organised. Ship- ments of rubber up to date have been 300,00, lb. and further 600,000 Ib. has been collected and will be gradually shipped.” This Company probably owns the largest quan- tity of indigenous rubber trees of any English Company. We wish distinctly to emphasise the fact that the total production of rubber per annum is about 70,000 tons. Of this quantity only a little over 2,000 tons is produced from plantation rubber trees in the East, The entire balance is obtained from indigenous rubber trees. We further wish particularly to empha- siseo the fact that the production of rubber per tree from planted trees in the East is only about 1 lb, as against 4 1b. from the indigenous trecs in South America. An interim dividend of 3 per cent was paid in July. It is expected the first report and balance sheet will shortly be issued, aad that the divi- dend will amount to at least 10 per cent. This, it is expected, will be more than doubled next year, and continue to largely increase from year to year ; in fact, from the official figures already given it appears the Company should have no difficulty in paying 80 per cent dividend next year.

Before the Neboda Tea Co. of Ceylon on Feb. 13th., Mr. Joseph Fraser made a most im- portant statement on the question of burying vs burning of tea prunings, which is given below. ith prunings buried (with basic slag, &c.) one division showed as large a yield as 1,179 lb. per acre. Another estate visi- ted by Mr. Fraser is quoted in support of “burying ”: on this there was a definite experi- went. Before treatment the yield per acre on one field was 300 lb. and after four years 920 lb, —while on an artificially manured field ad- joining it had increased to 690 lb. only. Simi- larly upcountry, burying prunings with bulk artifi- cial manure and albizzia leaves and twigs brought the yields up to an average of nearly 1,100 |b, with a maximum of 1,481 1b. per acre! The figures as to cost we commend to the attention of planters. As to whether Mr. John Hughes ‘‘oof mixed” in his references to manuring and burying, we may leave him to deal with more elaborately than we could; but Mr. Fraser, it should be pointed out, gives the most valu- able analytical figures, for the chemical and cultural results achieved, and emphasizes the cumulative effects of burying, with a proviso against its employment in root pest centres, stiff soil or bleak situations. Practical and scientific planters will be grateful for the full statement he presented at the Neboda meeting. MR. FRASERS’ STATEMENT. At the Annual Meeting of shareholders of the Neboda Tea Co. of Ceylon. Ltd. The CHAIRMAN (Mr. Joseph Fraser)—in moving the adoption of the report—said :—The results of the year’s working may be considered highly satisfactory. The average tea yield was 803 1b. per acre in- cluding 27 acres of Tea and Rubber. Allow- ing for manuring items, and loss on rice, the nett cost was a shade under 19 cents per lb. and the profit exclusive of loss on rice, which I trust is more or less a temporary item, R89°69 per acre or say £6 sterling. Narthupana divi- sion that has had the PRUNING SYSTEMATICALLY BURIED, with the Basic Slag and Sulphate of potash, plus artificial manure, gave from the whole 227 acres an average yield of 960 1b, per acre, the best yield being 1,179 Ib. A thoroughly cultivated field on the Neboda division 33 acres gave 987 lb. per acre, but 110 acres that were cultivated only occasionally, the labour not being available, owing to rubber extensions, gave an average of 687 lb. per acre, while two fields of 57 acres, never manured or cultivated, only yielded 309 lb. per acre. They were, however, pruned within the year, but the aver- age for two years was under 400 lb. and that too from fine indigenous tea. Tho results therefore of burying prunings, plus manuring, in this instance, seem fully justified, 37 289 A DEFINITE EXPERIMENT in two adjoining fields, on an estate I visit, further confirms this. They have the same aspect, lay of land, and soil, and were yield- ing an average in the pruned, and unpruned years, before they were manured, or cultivated, of under 300 lb. per acre, per annum. One field had the prunings buried with Basic Slag and Sulphate of potash and six months afterwards was manured with artificial. The other field was manured with a similar mix- ture of artificial only, at a corresponding period from pruning, and in both instances, this has been repeated four times or for eight years, the fields being pruned every two years. The first two years the advantage of burying prunings was small, and showed a loss, if charged with the Basic Slag and Sulphate of potash, the second covered cost, and the third showed a profit, that is compared to the field treated with artificial manure only. The fourth, however, was highly satisfactory. The average yield from the field manured with artificial for the two years, ending 31st December, 1908 was 690 lb. per acre and from the buried prunings and manured field ... 920 increase a --» 230 yD An increase of 2301b,, per annum or 460 lb. for the two years with the following financial results :— Crop expenses plucking to f.0.b, 14 cents per lb. rf en Cost of cooly labour burying plus cost of Basic Slag and sulphate of potash R20°60 ng, R64°40 Total ... Soo R85°00 Value of 460 lb. of tea at 35 cent ... RI6L°00 Nett additional profit for 2 years... R76-00 As regards the size of the bushes, the class of pruning wood,their healthy, vigorous look and freedom from pests, the advantage all along was clearly in favour of the buried prunings and manured field. On another group at from 2,600 feet to 4,600 feet above sea level the following results have been secured by burying prunings with bulk and Albizzia leaves and twigs and artifi- cial, in three fields aggregating 94 acres, 1,064, 1,057 and 1,165 lb. per acre per annum for the past three years, the highest yield in any one year being 1,481 lb, per acre—results are not generally so apparent, particularly in poor old coffee land soils, with miserably stunted bushes, but the indirect advantages in developing heal- thy ones with good pruning wood can seldom be questioned. The actual cost of burying prunings, in cooly labour, is from say R4 per acre for small bushes up to R10 to R12 per acre even for very large ones, but in that case the bushes run from 30 to 36 months from prunings. Allow- ing the yield to vary from 400 lb. to 1,200 Ib. per acre per annum, the cost would work out for a 2-yearly pruning at 4 cent per lb. and less when the 3-yearly system is adopted. Mr John Alughes evidently got sadly mixed in regard to this, and appears to have included, all the manuring items under burying prunings. The following figures are interesting in this connection ;—= Phosphoric Acid lb. per acre. Nitrogen Potash lb. lb. per acre. per acre, Loss of essential fertilis- ing constituents by a crop of 1,000 lb. made tea per acre at Essential constituents in prunings from a_ hard ¢ plucked pruned field un- manured per acre per annum Lowcountry Prunings from bushes care- fully plucked and pruned and lightly manured per acre per annum Low- country 6g Prunings from an un- manured well pruned and plucked medium ele- vation estate old coffee land per acre per annum Prunings from a_ highly manured well plucked and pruned medium estate large well devel- oped bushes per acre per annum -. 101°48 78°00 23°83 The above would indicate that the burying of prunings is clearly cumulative in its effects and may saiely be carried out except in cold bleak situations and in stiff soil, or where Rosellinia or other allied root pests are distinctly trouble- some. The total cultivated area is 1,121 acres or R303 per acre on the paid up capital of the Com- pany say £20 4s Od sterling—the 694 acres of Rubber including the cost of land stands us on 31st December 1908 in R221°51 per acre with 120 acres now in bearing. The Rubber crop for 1908 was 8,683 lb. and realised R3‘06 per Ib. nett which may be considered satistactory as prices were poor in the early part of this season. The estimate for 1909 is 20,000 lb. The cost of upkeep of the Rubber clearings is now very small, weeding varying from 30 cents per acre per month to Rl per acre that being the highest rate we are now paying. Mr. Callander is to be congratulated on his thorough work in this respect, he being fully alive to the necessity of removing all weeds before they seed, the only method whereby cheap and efficient work can be secured, Real clean weeding, means as a rule, labour well under control, with the iull advantage that it can be efficiently adjusted, to requirements without waste. A contract for a Rubber Factory has been given out, coolies are ample for require- ments and all the coast advances are quite safe. They stand in at R22°20 per head. With these remarks I beg to move the adoption of the report. 45 22% 8 17°14 7°75 47°60 67°12 20°66 35°35 17°46 5°08 THE GOVERNMENT MYCOLOGIST ADVO- CATES BURNING OF PRUNINGS. The question at issue is whether the burning or burying of tea prunings is the most econo- mical and safe method of disposing of them. Mr. Joseph Fraser has given particulars of a system of cultivation employed upon a certain estate, which included the burying of -prunings. The estate in question showed excel- lent results from the commencement of this treat- ment. Mr. T. Petch, the Government Mycologist —an advocate of the burning of prunings —favours us withthe following letter criticising Mr. Fraser’s conclusions. Mr. Petch is not prepared to The Supplement to the Tropical Agriculturist admit that the results, quoted by Mr. Fraser, are due to the systematic burying of prunings. There is nothing to show, he argues, that the improved yield is not due to the other com- ponent parts of the scheme of cultivation ; or to justify the belief that the results would not have been the same, had the prunings not been buried. Mr. Petch reasons ably and ingeniously froma scientific standpoint ; but we hardly think his arguments will convince the practical planter, who is seeking for the best method of economically disposing of his prunings and at the same time getting the maximum yield from his tea. It is demonstrated by Mr. Fraser that a system of cultivation which includes as an essential part the burying of prunings results in substantially increased crops. It1s, to use an Americanism, ‘Cup to” the critics of this system to demon- strate that equally good or better results, can be secured by the same system minus the burying of prunings. As matters stand, if Mr. Fraser, as is asserted, supplies no data to shew that the burying of prunings contributes largely to these results, Mr. Petch equally fails to prove that it does not. The ordinary ‘“‘ man in the tea,” not possessed of the same deep scientific knowledge as Mr Petch and Mr Fraser, will be content with the knowledge that here isa successful system of cultivation of which burying prunings is said to be an essential part ; he will be content to follow the system and secure increased crops until it is demonstrated —if it can be—that the same results can be secured without burying the prunings. Mr Joseph Fraser is a busy man, who has fre- quently declared time will not permit him to carry on newspaper controversies ; but there are one or two points in Mr Petch’s criticism, on which a brief statement in reply would be welcomed and might not necessarily require to be followed by others. Mir. T. Petch’s Criticism of Mr. Joseph Fraser’s ‘*Neboda” Statement. Feb. 18th. Sir,-The figures quoted for Mahawale(see page 188 of last month’s issue of T.A.and Mag. of C. A.S.)and other estate must be very satisfactory re- ading for the shareholders, but they give no infor- mation whatever on the pointatissue. And I may forestall those who think that this may be answered by stating that the financial side—and not the theoretical side—is of more importance to the employer, by pointing outthat there is nothing to indicate that the same results would not have been obtained if the prunings had been omitted, Consider the case of Mahawale: (1) Prunings are buried and (2) the land thereby cultivated to some extent, (3) Manure has been applied, (4) Albizzia leaves have been buried, (5) Rubber has been planted through the tea, And the crop since this was begun in 1904 has been 482 ; 552; 578; 746, and 807 |b. per acre perannum. But why select No. 1, and deduce that the burial of prunings is beneficial? Should I not be equally justified in assuming from the data that interplanting with rubber is beneficial? There are five factors, and it is impossible to separate them, Itis magnificent, but it is not experiment, and Magazine uf the Ceylon Agricultural Society: Why not go back to 1902 when the yield, as far as I can discover, was 182 lb. per acre? How did it become 420 lb, in 1903, without manure, or prunings, or albizzias? The increases for the years given are 14°5, 4'7, 29, and 82 per cent. It would be interesting to know the reason of these periodic differences in the annual increase: is it pure chance that the greater coincide with the two great increases in the total Ceylon crop since 1904? It may be pointed out, by the way, that a difference of 8 per cent. in a field experi- ment is regarded as inconclusive. Some fields yielded 700 lb. per acre in 1904: have they shared in the general increase, and do they now yield 1,150 lb. per acre? How isit that Mahawale shows in one year again of 14 per cent., when ‘‘from the burying of prunings, quick returns are not to be looked for, or ex- pected,” and another estate, more liberally treated, does not show a profit for four years ? But when was Mahawale opened ? I do not find it in the Directory for 1896-7, And were the 650 acres of tea all planted at the same time ? Apart from the fact that itis not an experiment in burying tea prunings, it would appear that all the cards are not on the table in this case. Take now the ‘‘definite experiment” on two adjoining fields. The average crop for the two was under 300 lb. peracre. It is unfortunate that the yields are not given separately, because if one gave 330 lb. and the other 270 lb., the bot- tom is knocked clean out of the experiment. But this does not affect the value of the experiment from the point of view of the present discussion, *‘A” had cultivation, buried prunings, basic slag, sulphate of potash, and artificial manure. B had artificial manure only ; aud the two fields were not treated at the same time, This last may be a minor detail: Still, it is best to avoid all pos- sible errors in making a ‘‘ definite experiment.” After eight years’ treatment, A shows an ad- vantage of 33 percent. per annum over B. It is no doubt a successful experiment in manuring tea ; but if it was designed to show the benefit derived from burying prunings, it was most hopelessly misconceived. It only shows that the treatment accorded lo A gives a better yield than the treatment accorded to B. Butdothe culti- vation, and the basic slag, and the sulphate of potash count for nothing ? How much of the gain is due to each ? To make a difference in four factors (or five, if the time is taken into account), and then to quote the result as a proof of the ad- vantage of one of them, is utterly unjustifiable, and it supports the previous contention that what passes for experiment in tropical agri- culture is often the most feeble imitation. Ex- amples of such ‘‘experiments” can be quoted by the dozen, and none of them proves any- thing ‘‘definite.” Zo obtain any evidence on the subject of burying prunings, B should have re- ceived exactly the same treatment as A, minus the prunings, at the same time, even to the ex- tent of digging holes and filling them up again, and there should have been a control plot. I have been referred to theories and figures sent some years ago to the Experiment Station Committee. The figures there are nearly those published in Saturday’s issue, viz., that the prunings from @ highly-manured, well-plucked, 291 medium-pruned estate, with large well deve- loped bushes, remove 101 |b. of nitrogen per annum, etc. Presumably this is 202 lb. per pruning. The figures are indisputable. I do not mean that they are correct, but that they are not open to discussion. We might just as well be told the total of an obliterated column of figures, and asked to discuss its accuracy. If the justification of the burial of prunings is to be based on their manurial value, the figures must be supported by details which give them some semblance of probability, Some idea of the accuracy of the figures cited above may be gathered from the fol- lowing sentence, which is quoted from the manuscript referred to: ‘‘It does not appear financially sound to throw or waste tea pru- ei containing 4 to 4% per cent. of nitrogen in their dry substance, to be replaced by orga- nic matter containing 2‘) to 4 percent. at most, even though secured from the nitrogen of the air by the aid of nodule bacteria.” It certainly does not : but whoever claims that tea prunings contain 4 per cent. of nitrogen in their dry substance? We are told that the leaves (dry) contain 44 per cent. Surely itis obvious that the great mass of the pruningsconsists of wood which has only a small nitrogen content. In the absence of details we are left to guess where the fallacies lie; but the two most pro- bable are: (1) the nitrogen content of the leaves is applied to the whole of the prunings, and (2) there is a confusion of ‘twet weight” with ‘‘dry weight.” Percentages, to be of any use, must be calculated on the dry weight, ‘.¢., after drying at 100° Cent. until constant. The figures for Hevea give a typical example. The leaves (dry) contain 3°44 per cent. of nitro- gon; the twigs, °62 per cent. ; and the wood, °59 per cent. What are the corresponding figures for tea?—and will the nitrogen content of the whole of the prunings exceed 1°5 per cent? To estimate this we must know the dry weights of the leaves and green twigs, red wood, and old wood removed per acre, and the nitrogen con- tent of each. As far as regards loss of weight, on drying, old tea leaves lose over 60 per cent., green shoots with full-grown leaves lose over 70 per cent., red wood loses 69 per cent, and old loses over 50 per cent. 202 Ib. of nitrogen are said to be removed in the prunings of oneacre. If we take the nitro- gen percentage as 4, this requires 5,050 lb. of ry prunings: and putting the average loss of weight indrying at 60 per cent., this means 12,500 Ib. of prunings in their natural condition. But this percentage of nitrogen is most probably three times too great, and, therefore, the pru- nings required will be about 37,500 lb per acre. To illustrate our lack of facts,— can any planter say, to half-a-ton, what weight of prunings is removed per acre on his estate ? I hope the above will give some idea of the figures and experiments required to solve this question. At present those who advocate the burial of prunings because of their manurial value, give no valid basis whatever for their belief. We do not know how much nitrogen or what weight of dry material is removed 292 per acre. And when the first of these points has been settled, there still remains the ques- tion raised in my article on Tea Root Diseases, viz., how much of this nitrogen ever becomes available for the plant ? T. PETCH. MR. JOSEPH FRASER IN REPLY TO MR. T. PETCH. We are obliged to Mr. Joseph Fraser for the following letter he favours us with replying to some of the criticisms made on _ his Neboda statement by Mr. ‘ Petch, the Government Mycologist, With regard to the two fields on Neboda which yielded under 300 lb. per acre before the definite ex- periment was made, Mr. Petch regretted that the yields were not given separately because, he said, if one had given 330 and the other 270 lb. the bottom was knocked clean out of the experiment. The fields, Mr. Fraser points out, were giving within 10 lb. of each other. Mr. Petch questioned the statement—‘ tea prunings containing 4 to 44 per cent. of nitro- gen in their dry substance.” He pointed out that prunings consisted mainly of wood which, he said had only ‘‘a small nitrogen content ” and he assumed that a wrong result had been arrived at by applying the nitrogen content of the leaves to the whole prunings and by some confusion of ‘“ wet weight ” with.* dry.” There were, it will be seen from Mr. Fraser’s reply, no such errors. The percentage of nit- rogen was calculated on the whole dry weight of the material, Mr. Fraser quotes a very striking instance from Mahawale. A field which was almost abandoned, being the poorest on the estate, after being cultivated and prunings systematically buried, gave an average of 1,001 lb. for the last two years! Mr. Fraser gives in anutshell the reasons for his firm belief in the burying of prunings and he concludes, what we venture to think will be regarded by those interested in the subject as a most valuable contribution to the controversy, by throwing down the gauntlet to those who differ from him, Recognising the shrewdness of the average Ceylon planter, Mr. Fraser declares that the planting community ‘‘will be only to pleased to adopt other methods, when they have been proved to be cheaper and more efficient in developing healthy well-nourished bushes, with fine pruning wood, plus a good field.” Will any planting champion of Burning Prunings ac- cepted the challenge ? Mr. Fraser’s REPLY. Kandy, Feb. 20th. S1t,—With reference to Mr Petch’s remarks on my Neboda statement, I seem to have not made myself cleat as regards the yields of the fields I used as anillustration. They gave before the experiment was started under 8001b. per acre per annum each, and within 10 |b. of each other. Regarding the analysis of the prunings they were calculated out on the dry weight of the material, and separate analyses were made of the leaves, and woody matter. [ supplied the figures as regards the weight of green matter, The Supplement to the Tropical Agriculiurist based onaseries of weighings of the average trees pruned and Mr Cochran, F.c,s. and the Colombo Commercial Co.’s Analysts supplied the remaining data. Referring to Mahawale, I may mention that what was originally the poorest field on the estate and, at one time, was all but abandoned, gave an average for the last two years of 1,001 lb. per acre per annum; and this I largely attribute to the burying of prunings, as in this instance, it was consistently carried out, whereas,in fields not so systematically treated and that were much better to start with,the yield had consider- ably fallen behind: My reason for believing in the burying of prunings is that I find when decay is more or less complete, the tea roots freely develop in this matrix and feed on its substances ; that the ana- lyses of these areas are richerin nitrogen than the surrounding ones. We also get rid of « great many topical pests, and that over large areas the danger from root disease is small. I feel sure, however, that the planting community generally will be only too pleased to adopt other methods, when they have been proved to be cheaper and more efficient in developing healthy, well-nourished bushes, with fine pru- ning wood, plus a good yield.—Yours faithfully, JOSEPH FRASER. ANOTHER CEYLON V.A.’S OPINION. A very weighty letter appears hereafter from Mr.Wm. Forsythe, strongly supporting the manu- ring policy recommended by Mr. Joseph Fraser which includes the burying of prunings. We attach considerable importance to Mr. Forsythe’s evidence. He is acknowledged a first-class practical planter, and is one of Ceylon’s best-known V. A.’s, whose judgment invariably commaads respect among his fellow- planters. He has had long experience of the burying of prunings and the support which he gives to Mr. Fraser’s system is based entirely on his own practical experience of its advantages. Few tea planters, if any, know Low Country conditions better than our correspondent. Mr.M L Wilkins, one of the younger school of prominent and successful scientific planters, also indirectly supports the burying of pru- nings. Mr. Wilkins wants to know if Mr. Petch’s letters are private or official. We should say ofticial ; Mr. Petch is merely defending the posi- tion he took up in his able paper which ap- peared in the 7ropical Agricuiturist. Mr, Petch is arguing from the point of view of the Myco- logist, and in a matter of this kind it is per- haps fairer to regard his opinions as the result of strong convictions, rather than prejudice— as hinted by our correspondent. Further, this is not by any means the first time that Doctors have disagreed, and the planters ought to carefully study for themselves what treatment should best suit their case. We think, too, that even during the present discussion it has been indisputably demonstrated that situa- tions are conceivable where the burying of pru- nings would not be recommended even by Mr. Fraser as bejng attended by the possible risky and Magazine of the Ceylon Agricultural Society. Raed out by Mr Petch. In the lowcountry, owever, where decay is more rapid, we think the balance of opinion is beyond all doubt in favour of the beneficial results of burying prunings. We should very much like it, on the principle of Aud) Alteram Partem, if any planter, should such exist, who has been less fortunate in his experience of burying prunings than those planters whose views have already appeared, would come forward now and state their views. THE BURIAL OF PRUNINGS.—I. Feb. 25th. Srr,—It occurs to me to enquire whether Mr. Petch’s letters on this subject are private or official ? [f the former, I suppose, like the rest of us, he is entitled to his likes and dislikes ; but if his communications are official, do you not think that they would have much more weight and authority if there was less flavour of prejudice, and a greater disposition to deal with both sides of the question ? We have heard all about the possible dis- advantages, minimum of nitrogen in prunings, etc., etc., but will Mr. Petch dace that there are any possible advantages in the burying of prunings? What about: (1) Humus or organic matter, (2) Potash, (3) Eradication of pests, (4) Improvement of the mechanical condition of the soil, etc ? We have been told about: (1) in connection with green manures by Mr. Petch’s colleagues, and re (3) I think Mr. Green advocated burying in one of his recent circulars on shot-hole-borer? If our experts are going to contradict each other, what are we to believe? Many of our leading practical and successful planters seem to be of the opinion that, amongst other advantages the burial of prunings with slag, etc., improves both the bush and the quality of its produce. If there is anything in this opinion, and if Mr. Petch’s views influence us against it, it stands to reason that such views are hardly in the best interests of the industry as a whole.—I am, Sir, M. L. WILKINS. II. Ireby, Norwood, Feb. 25th. Sir,—I have read with the deepest interest Mr. Petch’s letter with reference to the burying of tea prunings and Mr. Fraser’s in reply. I have carried out this so-called Fraser system for many years upon low-country tea estates and with the greatest possible benefit to the bushes which, in every case, have improved in stamina, and yield in a way I could never have believed. The properties, which I have had the good for- tune to control and work for many years, speak for themselves. I remember them when they were run down and I[ know them as they are now. A continuity of artificial manuring and nothing - else eventually proved ineffective in keeping up the bushes and the yield ; and I was driven to work in organic matter into the land, with the results so clearly described by Mr. Fraser. I _ geally cannot say what would have happened— 293 1, If I had simply cut holes for burying prunings, and filled them in again—minus the prunings. If I had buried prunings only without slag or potash. 3. If 1 had applied slag and potash to the land without cutting holes or burying prunings. But I do know that if I had done nething at all, but applied artificial manure, I could not have maintained in the low-country the vigour of the bushes and the yield, and I say this because I tried and [ failed many yearsago. This is not a scientific letter, but is written to give my practical working experience of cultivating low-ccuntry tea for, I should say, 10 to 15 years. 7) “se I venture, however, to re-echo Mr. Fraser’s pious hope; and to state that if anybody will come along and show me how I can achieve the same or better results in a cheaper and more effective manner, I will throw Mr. Fraser and all his works to the winds! Until that day comes, I am satisfied to continue working upon the lines which years of experience have proved to me are, so far as our present knowledge goes, indisputably the best.—Yours faithfully, W. FORSYTHE. III, Feb, 20th, Dear Sir,—e Mr. Petch on the Burying of Prunings :—*t At present those who advocate the burial of prunings, because of the manu- rial value, give no valid basis whatever for their belief.” I venture to refer to pages 108 and 109 in Carpenter’s Vegetable Physiology, edited by Edwin Lankester. From page 108 I take the following :—‘‘ Nothing more, says a vine-grower on the banks of the Rhine, is necessary for the raanure of a vineyard than the branches which are cut from the vines themselves (printed in italics), The other day I heard on excellent authority that the late Mr. Wall frequently used your correspondence column to advocate that the vineyard system of burying prunings was a type of cultivation eminently suited for the Ceylon tea field.—I am, Sir, &c., A. G. C, LV. Lindula, Feb, 26th, Deak Six,—I would appear to be in good company as to burying of prunings with Messrs, Hughes and Petch. That correspondent, who writes to the press re vines and this style of cultivation, has forgotten the fesult, “ Phyl- loxera.” Holes have to be cut tocarry tea prunings and they become rain catchers and hence the beneficial results. Up here I can prove itto the hilt by ocular demonstration, where nothing but holing has been resorted to and all prunings left on the surface. I have no doubt white-ants in the lowcountry eat them up at once. In these districts we have no such insects. Yours, &., E, R. WIGGIN, 294 [Mr E R Wiggin isa valiamt opponent of the burying of prunings; but somehow he never seems to carry us much further towards definite information on the subject. No one will dispute that the mere cutting of holes—involving the aération of the soil—is attended by a certain amount of benefit ; but if our correspondent means to suggest that the improved yields in the fields mentioned by Mr Joseph Fraser is simply due to the cutting of “rain catchers”!— we would be inclined to leave the suggestion to be laughed out of court by all practical planters. Mr Wiggin renounces all claim to be taken seriously when he tries to account for the rapid decay of the prunings in the low country by stating that they are eaten up by white ants !—Ep., C.0.] THE BURIAL OF TEA PRUNINGS. Three further letters on this important contro- versy appear hereafter. Mr E R Wiggin quotes the authority of Dr. Mann to support the case against burying ; but it is a qualified opinion. Dr. Mann recommends the burning of prun- ings it blights or pests are prevalent in the estate. We may state his opinion :— “To leave prunings lying about in a garden with these blights on them is suicidal, and to bury them is dangerous. Ifthe garden is, how- ever, free from Bight, there does not seem any absolute reason against burying the light prunings—and these only—provided the follow- ing conditions are adhered to :— **(1) They must be buried deep. At least 6 in. of soil should be left on top of them, so that they will not be turned up by the hoe. ‘*(2) They should be buried immediately on pruning, or as soon after as possible. In Ceylon, trenches are dug to receive the prunings before the bushes are touched at all, and the prunings are put into them practically at once. Once dried up, much of the manurial value has gone or is rendered less valuable. ‘*(3) They should be buried with something which will destroy any latent germs or spores ot fungi which are upon them, The best materials for this are lime and basic slag, which not only cause the blight spores to be destroyed but also the prunings to rot more quickly.” But what says Mr Claud Bald in his ‘Indian Tea: its Culture and Manufacture ” ? He believes in burying prunings, ‘‘ which are of great value as a manure, especially if buried deeply and in a green state.”” He says :— *‘Valuable manurial properties have been destroyed by burning the prunings, while, as compared with other gardens where the prunings have not been burnt, there has been no apparent result in the direction of sub- duing the pests. Theoretically the ashes are distributed to form manure for the whole ground ; in most instances, however, this is mere theory, as the ashes of an acre of prunings are usually distributed over put a few square ards of land.” With regard to Mr Wiggin’s experience we note uoted in a pamphlet entitled “ The Fertilisation of Tea” by George A Cowie, M.A.,B.Sc. which reached us some days ago, theopinionof Mr W B jackson, for many years manager of the Haute- ville Group of Estates, He commenced burying The Supplement to the Tropical Agriculturist prunings in 1894 and the estate has continued doing so since, burying alternately with lime and basic slag. ‘‘ I know of no bad results,” says Mr Jackson, ‘‘from this practice ; but of many good results ; and we are now as much in favour of this plan as ever we were.” This opinion must, of course, have been given some time ago; but it is important as showing that even upcountry, with the exercise of judgment, prunings may be advantageously buried. Mr James M B Duncan writes an interesting and fair letter on the ques- tion. He approaches the subject in the same spirit as ourselves, viz., with an open mind and an anxiety to learn allthere is to be known pro and con. Lastly we have an important letter from Mr Petch himself, . Mr Petch quotes figures to sup- port his contention that the amount of nitrogen In prunings is less than 4 to 4% per cent. as stated by Mr Joseph Fraser. We can find no independent authority on this point at present but Mr Bald refers to prunings ‘‘as a manure of great value.” Mr Petch points out that he has at present 109 estates on the root disease list. It would be interesting to know how many of these owe or attribute the disease to the burying of prunings. Mr Petch also repudiates the suggestion of prejudice. He is dealing with the matter from the standpoint of the Mycolo- gist and puts evidence forward that gives some ground at any rate for his expressed fears. As the evidence in the case stands at present, however, we are inclined to think the practi- cal tea planter will be more attracted to the burying of prunings by the glamour of its good results than repelled by the terrors of possible’ root diseases. Ts Lindula, March 2nd. Sir,—I omitted to give the late Dr. Watt, the expert of the Indian Government for tea. He absolutely condemns the burying of prunings. Let those laugh that win. I am content to rest on my experience and results. The estate, I am today writing from, has been systematically rain-holed without that other cultivation and the crop for 1908 was 578 lb. per acre in a ring fence of made tea, : no mean result in a short season.— Yours, &c., E. R. WIGGIN. ne Doragalla Group, Pussellawa, March 1st. Dear Sir,—This subject having considerably interested me for some years past—to the extent of my making various little practical experiments on my own beside doing a good deal of burying prunings in the regular way during the past nine years--I have read the recent letters by Mr Petch and others with very much interest. The pith of Mr Petch’s letter appears to me to be contained in this quotation from it: ‘‘There is nothing to indicate that the same results would not have been obtained if the prunings had been omitted.” I have this morning re- turned from the examination of holes in a field where prunings were buried with basic slag and sulphate of potash a year ago last December. The holesin all cases show arich-looking dark mould, full of rootlets, etc., while the woody portions of the prunings have rotted away, and Magazine of the Ceylon Agricultural Society. This appearance is precisely similar to that pre- sented by other holes dug up by me upon former occasions. [ want to state Mr Petch’s conditions fairly as well as I understand them, viz :—If I had cut the same holes, mixed with the earth taken out the same quantity, say, about 5 oz. of basic slag and sulphate of potash and refilled into the holes again, omitting the prunings—will anyone contend for one moment that these holes would now present the same dark-coloured rich manurial- looking appearance, full of rootlets ?—in which the rootlets of vegetation seem simply to luxu- riate, fourteen months after this small quantity of, say, 1} oz. of basic slag and _ sul- phate of potash per tea tree was applied, had the prunings been omitted? And as_ to how the field is doing: In appearance it is grandly healthy. It has just given 106 pounds of made tea per acre for this last short month of February. But here I will be fair and hasten to state that the field was manured last October in alternate lines, viz., those in which the prunings had not been buried and the fine yield is no doubt largely due tv the manure put in. The field has given to date 5201b. for 8 months with the best months to run, our year ending 30th June, by which time I expect it will have given 800 to 900 Ib. tea. The elevation of these estates would run from about 3,500 up to near 5,000 and this particular field would be, I should say, about 4,000 feot. The field has heen worked up from an average yield of 4301b. for seasons 1898-9, 1899-1900. Although giving these additional particulars in order tobe quite fair, let us narrow the issue down to—as Mr Petch pithily puts it—as to whether ‘‘the same results would not have been obtained if the prunings had been omitted.” My belief, or, say, my expectation, is that the rich fertile appearance of the dug-up holes, full of rootlets, would not be now apparent had only, say, 5 oz of basic slag and sulphate of potash per hole to every four trees been applied 14 months ago, all other conditions being equal excepting onlu the omission of the prunings. Of course, it is admitted that burying prunings would nof suit every soil and all conditions without exception. Commenting on manuring vineyards with vine branches another correspondent suggests the result “Phylloxera,” but as you practically say in yourcomment he does not definitely connect the effect he gives with the cause he assigns. We know how very non-moral nature is: how human cannibals have been found physically and generally fitter than neighbouring non-canribals, and how much cannibalism there is throughout nature; so that the objections to burying pru- nings must be looked for vutside that idea, I rayself can supply one great objection if labour is short, viz., that the work is expensive in cooly labour and this objection appeals very forcibly to the man who has to get everything done and wants to apply his labour elsewhere. In the meantime my own attitude of mind is an open one anxious to learn all I can upon the subject of cultivation in its various branches. Thanking Messrs, Petch, Fraser and others for their letters on the subject, —Iam, dear Sir, yours faithfully, JAS, M, B. DUNCAN, 295 III. Mr. Petch Explains His Position. March Ist. Six,—Mr, Cochran's figures support my state- ment that tea prunings do not contain 4 per cent of nitrogen. He analysed the prunings of 10 bushes, from Madulkele estate, They were divided into two lots,—leaves, seeds and twigs weighing (dry) 56°67 ounces, and twigs and branches weighing (dry) 46°257 ounces. The first gave 2°794 per cent.,and the second 1°26 per cent. of nitrogen. The total dry weight was 102°927 ounces, containing 2-1 per cent. of nitrogen. Taking 3,110 bushes to the acre (Mr. Cochran’s estimate) the prunings remove 42 lb. of nitrogen per acre, or, on a two-yearly pru- ning, 21 lb. per annum. The total dry weight of the prunings is 2,000 Ib, per acre, or, assuming as before that they lose 60 per cent. on drying, 5,000 lb. of green prunings peracre. If the pruning is heavier, more wood is removed, and the percentage of nitrogen is diminished. There is a misconception current with regard to the relation of tea roots to the holesin which prunings are buried. The direction andamount of growth of roots is governed chiefly by the water supply, and the roots “seek” the pru- ning holes because the soil there is moister. The material for the formation of these roots comes from the bush. May I trespass further on your space to re- state my position? As the burying of prunings of any cultivation, among the trees or bushes from which they are taken, is a most extraordi- nary proceeding from a mycological standpoint, I raised the question in an article on Tea Root Diseases in 19V6._ 't must have been discussed without ‘‘ prejudice,” because it has since been quoted in favour of both burying and burning! I was told that the whole question had been worked out long ago, and all details were known. But I could not get at them, at least at anything definite. Recently [ have had occasion to in- vestigate a new tea root disease, as far as time permitted, and I took advantage of the first op- portunity to re-open the subject. This time we have been put in possession of the facts relied on by the ‘‘other side”; and I have ventured to criticise them, I think I have shown that the amount of nitrogen in the prunings is not the 4 percent. claimed, and that the experiments are not such as would carry conviction at, say, Rothamstead, or Woburn, or Wisley. ; Of course, the whole question is a matter of balancing losses and gains: and te me the gains appear to have been over-estimated. But Il have no prejudice in the matter, beyond a prejudice against unnecessary, 7. ¢., avoid- able, diseases. Root diseases of tea were first brought to notice in 1901, and I have now 109 tea estates on the root disease list. That is, 109 estates have sent in specimens for re- port. Others have been seen when on tour, and many estates do not bring their diseases to Peradeniya. The advantages of burying prunings are :— (1) A gain in humus, (2) A certain amount of cultivation, (3) A gain in manures, 296 I consider that too much has been made of the third point ; that most of the advantage is due to the second; and that this can be obtained by less dangerous methods. Destruction of pests by burying seems to me very doubtful, unless they are caterpillars and get squashed. Certainly no fungus is killed by burying it. As regards the disadvantages, the following points are beyond doubt :— 1. The conversion of prunings into humus is brought about by the action of fungi. These fungi are for the most part saprophytic, ¢.¢. they Jive on dead substances. 2. Asaprophyte can be converted into a para- site on the living tea bush if itis habituated to tea prunings, 3. Allour tez root disease fungi are initially saprophytes, Even the tea leaf fungus, Gray Blight, lives far more vigorously as asaprophy te than as a parasite. 4. Our newest tea root disease is caused bya fungus which liveson pruninys, either buried or on the surface: likethe others, itis an edu- cated saprophyte. As practical results are preferred, I quote the following from a recent letter about the newest tea root disease:— ‘‘Tam sending you some dead tea stumps and roots. For the past nine years each field, where possible, has had its prunings buried atthe time of pruning, which would be every second year. One hole to every four trees every othertime. Anapplication of Basic slag and Potash is added to each hole. The following year the fieldis treated with artificial manure. In the particular field from which these roots are taken, there is a very considerable number of deaths,” T. PETCH. ‘*COMPRESSED’’ INDIAN TEA IN INDIA. Ata Meeting of the Indian Tea Association held last month— The CHarrMaNn—said that he had to invite the Committee to consider the recommenda- tion of the Executive Committee that a bonus of nine pies per lb. be offered ona mil- lion pounds of compressed tea to be sold in India. It would have been seen from the pro- ceedings of the meetings of the Executive Committee that this was a proposal which had originated in London. The attempt to manufacture compressed tea had been tried, he believed, tin India, but without any particular success. At home, however, it was under- stood that machinery which would press tea properly had been invented ; and he was informed that certain firms were prepared to interest themselves in the project and to giveit a trial. Although the Executive Committee did not expect any very great results from work in India, they recognised that there was a great potential market in the country, and they were willing therefore to make further efforts. Mr. H. C. Brac—then proposed and Mr. W D Cowan seconded :— ‘* Phat a bonus of nine pies per Pound be offered on a million pounds of compressed tea to be sold in India during the year ending 31st March, 1910.” The resolution was carried unanimously. The Sunplement to the Tropical Agriculturist VISIT OF A LONDON TEA MAN. INTERVIEW WITH MR. A. MANN OF MESSRS. JAMES FINLAY & CO. INTERESTING INFORMATION ON INDIAN TKA. Mr. A Mann, the Visiting Agent of Messrs. Finlay. Muir & Co., who, during the last few months, has been all over the North India tea’ gardens of the firm, and, latterly, the South India properties prior to spending ‘a month on the Ceylon estates, arrived in Ceylon recently and, in a conversation with a Ceylon Observer representative gave some interesting informa- tion relating to Indian tea, Prospects OF THE INDIAN TEA Crop, Mr. Mann was first asked what were the prospects of the coming season’s Indian tea crop, to which he replied: ‘‘ Not very good. Just now North Indiais suffering from a severe drought which had not broken when I left. We had only some two inches rainfall from the end of October up to the middle of February, and that fell in decimals—so that really it was not much use. Dibrugarh, though, has had a good rainfall, and they should start fairly well.” Is the area cultivated likely to extend ? No, it is not likely to extend much. Labour is the difficulty and itis getting more acute every year. ‘here is such a demand for it in mines, factories, railways, and that sort of thing. WEEDING. What are your views on the advantages or | otherwise of Indian methods of cultivation as compared with those of Ceylon? Well, of course, we stick to our ideas. Wee- ding would never do with us, ours is such a stiff soil that it has to be turned over. Wedon’t do weeding atall. We goin for one very deep hoe in the cold weather and five to six light hoeings throughout the year. We have no plucking from the end of November till the middle of March, the bushes rest then, and we prune every year. The climate and soil are, of course, quite dif- ferent. The soi] here 1s very open and friable, ours is not, ours is stiff. Weeding SEEMS TO SUIT CEYLON but it would simply ruin the North India gar- dens, I should think. The system pursued in both places is the correct one for the climate and soil. THE BURYING OF PRUNINGS. Do you believe in the burying of prunings ? Most decidedly. I am very strong on that point, and [ would go so far as to bury all dis- eased prunings even, unless there were a fungoid growth, They contain the nutriment ot what we want to put back in the soil and I consider it is THE Brest MANURE of any we can get. North Indian planters are very strong on burying prunings. Do you hold the same opinion with regard to Ceylon gardens ? I do not see why these remarks should not apply to Ceylon. As far as I have seen, both here and in South India I should think the burying of prunings would be most advanta- geous to the plant, and Magazine of the Ceylon Agricultural Society, Then,of course,you do not believe in burning ? 1! would only burn fungoid growth, thread blight and that sort of thing, The fungus rows on underneath the soil when it is covered. With regard to other prunings ! ehould be very strong on burying them, | Tua BRICKS, How do you view the proposed campaign to promote tea drinkmg among the: natives of India by the sale of tea bricks ? Itis away, of course, of getting rid of the poorer qualities of tea; but what we want to do is to get atthe agricultural people, so that Lhe, will buy it. Not only the people im the towns but the people in the agricultural districts, How do you recommend doing that ? Messrs. Andrew Yule & Co. carried outa scheme somo years,ago of solling pice packets to the natives, but it seems to have come to nothing. The only way to do it is to have AGENTS TO PUSH IT and get the housewives in agricultural districts to get a liking forit. It would be a difficult thing to get it introduced all over, it would take time. The bricks are made of a poor quality of tea because the noorer class would not pay the price for a good tea. The better class natives can always buy the ordinary tea. Altogether, I supposo, itis notagreat success? Well, it has not been a success so far. Do you think it will be ? * There is an idea of compressed tea now which may have a better result. The bricks will probably be abcut five pounds in weight, in factthey are already made so for Afghanistan. It takes a LONG TIME to get rid of them, however, and the system has not made much headway. If they don’t make much headway in Afghan- istan, [ suppose they won't make much headway anywhere else ? Jam afraid not—no. Of course there are so many people downin the agricultural districts of Bengaland round there that if it were onceintro- duced there would be a big demand for it, once they take a liking for tea, Do you think they are likely to get a liking for it ? Oh, I think they will. Itis just a matter of time. It may be successful then and it may not? I think if they have the funds to keep it long enough before the public it may ; but, as I said before, it is not reaching the town people so much, asthe people in the country, the ryots, that should be aimed at. There is then a prospect of a demand being created if you can keep long enough at it ? I think so, yes. How are the bricks made? They are simply pressed by being hammered into amould, by hand, with an iron mallet. It is asimple operation, then ? Oh, yes, it’s simple enough. Of course ifit were to turn out a success, machinery would have to bo introduced to do it on a bigger scale, becruse it takes a long time by hand, Could they be improved ? They could be improved by machinery. In what way ? : They would look neater and it could also be done more expeditiously, 38 RUBBER IN COCHIN. Leasu or Forest Lawns, With reference to the advertisement in this issue from the Diwan of Cochin, the following is an oxtracth from the Order of the Cochin Govornment regarding the leaso of forest lands for the extension of rubber cultivation. The Order opens with a review of the previous action taken by the Durbar with regard to, leasing forest lands for planting of rubber and coflee, and then goes on to say :— It will be observed from the above review of the previous correspondence on the subject, that leases of forest lands for coffee or rubber cultivation have hitherto been granted more or less as au experimental measure and that no definite policy has been laid down to regulate the grant of such leases. Whereas in some cases applications have been refused, in others they were granted, and no consistent policy has hitherto been followed in disposing of the several applications that wore received from time to time. Before formulating a definite policy on the subject, it was necessary however to watch the progress of rubber cultivation started by the planters in the Palapilly, Puthucad and Vellani- kara Estates and also to ascertain whether the forest lands of the State are well adapted for the successtul cultivation of rubber. Mr. Cecil Hall, one of the most experienced planters of the State, was deputed to inspect forest lands in the Sholayar valley, and he made a report as to the EXCELLENT FACILITIES FOR RUBBER CULTIVATION in these parts. The Forest Working Plan Officer, Mr Govinda Menon, also reported that timber extraction would be prohibitive in this locality. In regard to the experiments already made, careful enquiries have now been made and it is reported thatthe results achieved so far have been eminently satisfactory and rubber is grow- ing remarkably well in all the three estates. In a pamphlet issued by the planters of Southern India on rubber cultivation in Travancore and Cochin, reference has been made to Covhin rubber in the following terms :— ** Rubber was first planted on any scale in 1905, when Mr KE Nicoll obtained a grant of forest land at Palapilly, behind the Government Teak Plantation. This was a well situated block, at the foot of the hills, with the Chemoni river running through the centre. Some forty acres were opened in 1905, and later on, in the same year, Mr G Windle, on behalf of a Syndicate, took up an adjoining block of forest now called Puthucad, In 1906 there were some 300 acres opened on each place, and in 1907 the balance of the land was opened, Puthucad being in all ’ some 65) acres and Palapilly nearly 500, the two places making a fine sheet of over 1,100 acres of rubber. The conditions here are very favourable, the elevation being almost sea level, rainfall about 150 inches, and surrounding hills sheltering the basin from wind. As a result growth has been remarkably fine and, according to those who have seen both, it may challenge comparison- with fine Straits growth. The plantations are some eight miles by cart road from the Puthucad station on the Cochin Railway and about 20 miles from the Coast. In 1906 also a grant of Government. forest, six miles from Trichur Railway sta- tion and lying on the main road from Trichur to Palghaut, was obtained by Messrs. i G Windle and R E Campbell Gompertz, who’ opened 400 acres and subsequently disposed of the block to the Cochin Rubber Company, Ltd., of Colombo, in whose name the Government title was issued. This consists of{1,000 acres in all, cf which 400 acres were opened in 1906, 200 in 1907, and 2U0 in 1908, 200 being forest. Mlevation and rainfall are much the same as at Puthucad and Palapilly, and growth has been excellent, There are, therefore, at present some 1,900 acrag 298 The Supplement to the Tropical Agriculturist of Para opened in Cochin. Many other applications for land have been made, but were refused by the Durbar (Cochin Government) onthe ground that it had to be seen whether rubber would be successful. There seems no rcom to doubt this now, ard itis to be hoped that further land may be available tothe public for tea as well as rubber. The forest slopes, which are now being tapped by the tramway might reasonably be surveyed with the view of opening suitable parts; there are probably 50 to 1,00,000 acres which would grow one or other of the above products without unduly interfering with forest resources,” The last observation is fully borne out by the inspection report of Mr Cecil Hall who inspected the lowelying hills and the valleys adjacent to the tramway and the rivers. His preliminary report contains the following remarks :— “T found a very large area of forest land eminently suitable for the cultivation and growth of Para rubber (Hevea Brasiliensis) as well as for tea and also a good deal of land about 2,000 feet elevation which would grow tine coffee and tea, but which is situated at too high an elevation for rubber cultivation. I found most excellent and suitable land for rubber both sides of the forest tramway from Parambikulam to where the tramway enters the low country and throughout the entire length, on both sides of the Sholayar river throughout its entire length and also on the both sides of the Parambikulam river from Orukombankutty whether this river leaves the tram- way and to where the river empties itself into the low country below the Adirapilly water-falls. Branching off from the tramway and the two rivers, there are several large valleys very sheltered and ideal spots from a planter’s point of view.” Having regard to the enquiries made from time to time and the successful experiments on rubber cultivation in the State, His Highness’ Government have now resolved to grant further leases of forest lands for the cultivation of rub- ber. The enquiries as to forest requirements show that lands to the extent of 5,500 acres in the valleys of Chemmoniand Muppilli rivers in the Palapilly forests, almost adjacent to the Palapilly and Puthucad estates where rubber has thrived so well, can well be opened out for rubber without prejudice to the forests. His Highness’ Government are, therefore, prepared now to RECEIVE APPLICATIONS FOR THIS EXTENT OF 5,500 ACRES as wellas for any extent of the land reported upon by Mr Cecil Hall in SHOLAYAR VALLEY UP TO 10,000 ACRES, for rubber cultivation on the following terms :— a. The areasavailable for assignment will be demarcated into 500-acre blocks, Any person may apply for several con- tiguous blocks. b. The upset price will be R25 per acre or R12,500 per block and include the value of the forest growth, sub- ject toclause(l) infra. The lease will be sold to the highest idder at an auction to be held at Trichurin the oftice of the Conservator of Forests on the 14th June, 1909. c. The sale will be conducted by the Conservator of Forests and subject toconfirmation by the Dewan, The successful bidder shall, at'the time of sale, pay down 25 per cent of the purchase money and the balance thereof shall be paid in full within 30 days after the communication to him of the conformation of sale by the Dewan, failing which he shall forfeit his deposit money and be held respon- sible for any loss the Sirkar may sustain by resellng the lands either by public auction or private contract. d. The Bewan reserves to himself the right to confirm or cancel any sale without assigning any reason. e. Bona fide application from planters and from the natives of the State who wish to investin rubber and pioneers of rubber plantation in the State will be given preferelce. ~ j. Thelands will bocharged with a minimum assess- ment of eight annas per acre for the first eight years of the lease and thereafter with an assessment of R2 per acre. The rate will be subject to enhancement in the open com- petition. This assessment shall be payable by lessees whether the rubber trees shall have begun to yield or not. g. All payments to be made by the lessees shall be recoverable as arrears of public revenue under provisions of the Cochin Revenue Recovery Regulation. h. Inthe event of the lessees raising any catch-crops, which, in the opinion of the Conservator of Forests, may be likely to render the lands so cultivated permanently unfit for the growth of valuable timber trees, the lessees shall be liable to pay a fine of R5 per every acre so cuiti- vated, and the crops so grown shall, at the option of the Conservator, be destroyed. i. Thelessees shall not be entitled to any minerals or allowed to quarry laterite, ground granite, etc., free of seigniorage, except for the bona side estate buildings. _j. No fire otherthan may be for ordinary use (in dwel- lings or factories upon the premises) shall be set to within the area hereby assigned unless a clear week’s notice thereof shall have been given to the Conservator and his consent shall have been obtained. h, All existing rights of way shall be kept open. t. The timber rights may, if necessary, be sold separately or with the land. His Highness’ Government reserve to themselves to sell both together or separately to the best advantage. : m. Asthe measurement of the land previous its being cleared may be more or less incorrect, the land to be again measured after it has been cleared, and the permanent rent to be assessed onthe area thus correctly ascertained. n.

The namo of Mr. Fritz Zorn of the well-known Stock Exchange Firm of Messrs. Zorn & Leigh- Hunt is not unknown in Ceylon and we ven- ture to think few will disagree with us when we pronounce him one of the most careful students and penetrating critics of the rubber industry in England today. My, Fritz Zorn is perhaps best known through his handy and useful manual of rubber planting Companies, comprising particulars of the leading Com- panies engaged in the cultivation of rubber (either alone or in conjuction with other crops) in tho Straits Settlements, Coylon, Borneo, Java, Sumatra, Southern India, &c., &&. The third edition of this book revised and brought up-to-date reaches us by this mail. It contains many new features including a review of the year 1908 in relation to rubber planting ; a table of fluctuations in the price of rubber for the last three years ; and highest and lowest prices of the leading Rubber Companies’ shares during 1907 and 1908. Another fresh feature, which will be found useful, is tho inclusion with regard to a number of pro- ducing Companies of ‘‘ unofficial estimates ” of the crops for future years. ‘The first of these uew features we find pregnant with shrewd comments and interesting deductions from the experience of the past year, upon which is. founded a eareful prediction ol the outlook for the future. The review is in our opinion quite one of the most useful of the 1908 rubber year which we have yet seen. The soundness of the authority and the interest of his subject warrants us referring to it at some length. Mr Zorn starts with a reference ‘to the slump of 1907-1908, and—after commenting on the profound ignorance of the facts which led to the depression being attri- buted to the overproduction of plantation rubber in the Middle Kast—remarks that the Wild Rubber industry must continue to domi- nate the situation for a considerable time to come; and as cultivated rubber can be produced at avery much cheaper rate than the Brazilian product, the fear of over-production must fora good while be a mere bogey, so far as plantation enterprises are concerned. The recovery in the value of the raw material, which has taken place contemporaneously with the passing away of the depressed conditions in the United States, which had been the true cause of the fall, he regards as affording ample proof of this. The figures regarding supply and demand_ in 1908 are carefully dealt with and a good deal of space is then devoted to the ‘‘ Share Market.” It is considered noteworthy by Mr Zorn that the recent improventent in the share market has been nothing like proportionate to the recovery inthe price of the raw material and, having regard to the increased profits which will accrue from the rise in rubber to companies that have reached the producing stage, he considers that at the existing quota- tions rnbber shares offer considerable scope to the investor. In spite of all difficulties, how- ever, Mr Zorn declares the market has shown a broadening tendency during the year and the - per lb. as the cost of production for 1908. 209 circle of investors putting their capital into the planting industry is steadily growing. He eres the Exhibition at the Olympia credit tor eing an important factor in bringing about this result. Dealing with the crises through which rubber passed in 1908 Mr, Zurn summarises its effects as follows:— First: The non-expert Rubber Investor got frightened by the slump and threw away his shares at rubbish prices. _ Second: The ‘ plungers” both here and in the East who (with plenty of expert know- ledge of the industry, but no proper sense of caution) had involved themselves in une wieldy commitments, both in regard to planting and share operations, for the most part had to ‘*go under.” Third : New planting has_beon brought down to much more reasonable limits, as there has necessarily been a general curtail- ment of extensions, Fourth : The management of the estates has been carefully overhauled and drastic economies effected, thus reducing the coat of production, _ Fifth : ‘f Wild cat” promotions of worth- less new Companies has been rendered practi- cally impossible, There is an interesting paragraph on the cost of production of plantation rubber. This iz put by Mr. Zorn at present at about 1s 6d per lb. Personally we shail be very much surprised if im Ceylon, at any rate, before many yoars the cost of production will not have decreased by half this sum.’ As estates gain experience in dealing with larger quantities and greater num- bers of trees, the tendency will be in the direction of reduced cost. Who would believe, when tea in Ceylon was as young an in- dustry as rubber is at present, that the cost of production would ever be reduced to the existing level? Already the costof rubber sold locally from Vogan estate has averaged 104d The review concludes with a reassuring pronounce- ment on ‘The Outlook”; under this head Mr. Zorn remarks that the annual reports which have Bepesred during the past twelve months have afforded a striking illustration of the advantages of low capitalisation when bad times have to be faced ; he adds that it cannot be denied that a moderate basis of capitalisation isone of the merits of most of the leading Rubber Planting Companies. Alluding to the Brazilian ‘‘valorisa- tion scheme” he pointsout that the main im- portance of the suggestion, asfaras the Eastern Planter is concerned, lies in the effect upon price and remarks that the scheme is at the same time a significant indication of the way in which Brazilis waking up to the potentialities of Eastern Rubber planting. It is hardly to be expected (and for the sake of expanding demand it is not to be desired) that rubber should main- tain its present high quotation, but Mr Zorn thinks that the fall, when it does come, will not be aserious one. He concludes as follows :— The underlying strength of the present posi- tion lies in the fact that, taking the World over, consumption of Rubber is more than equal to production, Consequently, the whole position 500 of the industry is remarkably healthy, and in- dications point tothe price remaining for several years to come at a level which will secure ex- ceedingly handsome returns to well-managed Plantation enterprises while in the more distant future there can be little doubt but that culti- vated Rubber will gradually displace the wild product as a mere case of ‘survival of the fittest.” Whatever may lie ahead of wild Rubber- producing concerns, therefore, the outlook for Plantation Companies appears distinctly bright. Altogether the manual is a most conveniert one for reference and should be on the office table of every one interested in the industry. THE MINIMUM COST OF RUBBER PRODUCTION in Ceylon at the present time—next to that of the Ceylon Tea Estates Co. (94d.), must surely be that attained on Vogan and Iddagodde estates in Kalutara, of the famous Company known by the former name. We are told that the cost of tapping only was 38-94 cents per lb., while the whole cost of production of the year’s crop of 23,246 Ib. (5,746lb above estimate) averaged 62 cents or just under 103d per lb. This included cost of tapping knives, upkeep, supervision, We. Even this will probably show an appreciable re- duction in 1909, for the new system of tapping is to be entered upon and the crop—estimated at 60,000 lb. or more than double that of 1908 —it is anticipated may be very much larger. For the present it is cautiously stated that the contract sale of biscuit and sheet at R3-10 will give a profit of R250 per 1b., making cost of pro- duction 60 cents only. We shall not be surprised if it is brought down to 55 cents or even below. THE PRUNING CF RUBBER. The question of pruning is still an unsettled one, and the’ majority of planters regard top- ping with disfayour, At any rate thumbnail runing is preferable to cutting ofa top two or tires inches long. In the latter case a leader never grows up; two or three branches come out’ of the same level and at a wide angle. Ina year ‘or two when their leaf spread is larger ono or more of these branches breaks off leavivg a ‘gaping wound in the stem, and which offers an entrance to wound-fungi. I think it is not wise to assert that pruning should or should not bo followed. Much depends on the situation, the soil, and the rapidity of growth of the trees. Certain trees branch naturally at a suitable height ; others grow up to 15 feet and higher without branching and these might certainly be helped by judicious pruning. It is generally recognised now that all branches should be cut off when quite young up toa height of at least 10 feet, as tapping will ultimately be done to this height at least; a good clean step is wanted, .and branches or big scars left where old strong branches had been cut off will only interfere with “high ‘tapping. Formerly when two _ branches grew off near the ground both were allowed to develop on the view that double the tapping area would be available. Planters with old trees find this isa mistake. Neither grows as thick as either would have done if alone. The foli- age of each is one side only and such trees being lop-sided are very liable to suffer from wind. The Supplement to the Tropical Agricultiunist “WARTS” AND ‘* PwWwAg.? The growths, commonly called ‘ warts ” or “peas,” are to be found on nearly all trees. Tap- ping does not appear to induce them as they are found on untapped trees of three years and older, U believe they are dormant buds. They should be taken out when quite young ; this is easily done by atap from a hammer or witha strong knife. The wound soon heals over com- pletely. The practice of many planters having their old trees examined systematically at perio- dical intervals for these excrescences is worthy of wider application. The rough outgrowths, often several square inches or even square feet in area, which usually begin at the bottom on trees where tho early tapping has been bad, seem to be a disease not due to any parasitic organism but to some derangement in the inter- nal economy af the tree induced perhaps by: severe tapping.—W J GaLLacueEr in the Séraits Agricultural Bulletin for March. SCARCITY OF TAPPERS IN THE F.M.S. We hear that, although there is no lack of raw or unskilled agricultural labour just at the pre- sent moment, many estates which are now coming into bearing areunable to give their full possible output of rubber because of the scarcity of competent tappers. This seems to be due toa disinclination on the part of managers to train ‘‘tree” coolies to tap, as it has been found that when they have become more or less skillful in © the use of the knife they frequently leave their original employment and sell their services fora higher wage elsewhere. However, if this scar- city of tappers causes fewer young trees to be tapped and so givesthem longer to mature, we are quite convinced that it will make for the benefit of the local rubber industry in the long run.—Penang Gazette, Feb. 24. j THE CHIEF RUBBER PEST IN THE MALAY STATES. & We direct attention to the following article we reproduce from the Straits Agricultural Bulletin, dealing with the Termes Gestroi, the rubber equivalent of the shot-hole borer in tea. It will be seen that the notes in ques- ‘tion refer to flat alluvial land of which there is comparatively little under rubber here,compared with the abundance of it in the Malay States. Whether on this account or for other reasous, the pest is not so bad in Ceylon ; but it has been found, especially in new clearings. It is well that the drastic treatment of it should be under- stood and the notes elsewhere ought to be per- used by all planters, especially those in charge of new clearings or newly planted property. it will be seen that thorough drainage is one of the best methods of keeping the pest in check, the termites seldcm crossing a sub-soil drain except by a log or wooden bridge, Allsuch. stray wood should therefore be carefully watched in addi- tion to other measures being taken, J, and Magazine of the Ceylon Agricultural Society. 301 “ THRM ES GESTROL.” In the whole of the past history of tropical agriculture in tea, coffee, cocoa, cinchona and spices, there have been four causes for dis- appointment and an awakening from the golden dreams with which various enterprises were originally commenced :— 1. Substitutes. 2. Synthetic production at alow cost. 3. Over-production. 4. Pests and Blights. The first three are beyond the control of the individual ; and if any reliance is to be placed on expert opinion, the rubber planter in the East has nothing to fear from them in his comparatively new vonture, but the fourth, z.c., Pests and Blights, comes well within his scope and it is his duty to leave nothing to' chance and do everything within his power to assure the success of the enterprise. So far we have one blight and one pest which may be considored as serious, i.¢., Homes senci- tostus and Termes gestroi, Fomes semitostus is a blight which, if taken in hand at once and treated according to the advice of the Government mycologist, Mr. W J Gallagher, will, Iam sure, be easily overcome as we have successfully dealt with the same class of blight in tea, coffee, etc., by dramage and application of lime. . Termes gestroi, however, is A VERY SERLOUS PEST and it was in recognition of this fact that, in my various endeavours to extermi- nate it, | collected a large number of queen termites ; these I showed to Messrs. Carru- thers and Pratt, who were much _ interested, as the queens evidently belonged to two or more species and it was quite possiblo the Queen gestroi, which had hitherto never been found, was amongst the collection. This re- sulted in the investigation by Mr. Pratt and I have been fortunate in being in possession of the valuable discoveries made by him, for a considerable time before they were published. Previous to Mr, Pratt’s discoveries with re- gard to the habits of 7. gestroi Twas much afraid that the pest would prove to be a heavy handicap to the Malay Peninsula in its com- petition with other rubber-producing coun- tries in the future and a serious though un- seen and therelore unrecognised loss, in the present. [ am now quite satisfied, however, that it can be altogether eradicated, In-my endeavours to exterminate tho pest as expe- ditiousiy and as cheaply as possible [I have arrived at some conclusions and methods which may be of use to my brother planters. The following notes refer to flat alluvial land:—.., Metuops or ExTERMINATION. On OLp Rupper TrEES.—It has to be deter- mined whether 7’. gestroi establish their termi- taria in the rubber trees tnemselves and on this point I have no data. If it should prove to be the case, fortunate is he who discovers an insecticide, or other means, by which the Queen cells may be reached, at a low cost and without destroying the tree, and thereby obtain the reward now being offered.’ On the other hand, our success in exterminating the pest depends upon the skill with which tho runs aro traced up to their base. If all timber is collected and destroyed, I feel convinced that if the attack does not entirely cease it will be very much diminished. On Youne Russer Hsrates,—I have found it cheapest and best to make a systematic search field by field and line by line for all timber which 1s known to be favoured by 7. Gestroi, cut them open with an axe or cross-cut saw and if they contain the slightest trace of the enemy, destroy them by burning. The danger of scorching the surrounding plants may be entirely done away with, oratleast greatly minimised, by burning in a trench keeping the fire covered with green stuff, and shielding the surrounding trees with sheets of corrugated iron, These should not lean against the rubber troes but be supported by sticks a short distance from them ; even if two or three rubber trees are de- stroyed by fire in this way, the damage done is more than compensated for, by the fact that one T gestrot termitarium is CAPABLE OF DESTROYING A SCORE Ok MORE OF TREES toa distance of two or three hundred feot. Where there is a sale for timber or charcoal, sound Meranti trees may be sawn up with ad- vantage and Kumpas can be converted into first class charcoal. A close watch should always be kept on land that has been cleared of timber, and if a tree is seen to be attacked, every endeavour should be made to discover the source of infection, which will invariably be found to be a buried root or stump, from which the termites make their way in search of food by means of tunnels. These may be found at a depth of 6” te 3’ below the surface of the ground. In flat land, I have never found them below the sub-soil water level, which of course is regulated by the efficiency of the drainage system. Theso tunnels are, as a rule(as Mr. Pratt says), sufficiently large to admit the imtroduction of an ordinary microscope slide though some- times smaller, they are perfectly smooth and are lined, with. a red substance, probably tho excreta.of the termites which takes its colour from the timber on which they have been feeding. This colouring greatly facilitates the following up of the tunnels ; but it is by no means an easy matter until the coolies become practised at it and see for themselves that they are doing real good and not merely following out some mad scheme of their masters, When the direc- tion of a tunnel is lost, it is very diflicult to pick it up again. I have found the surest means, of not losing it, is to use a piece ot thin flexible wire or strip of cane as a probe. Pass it into the tunnel as far as it will g0, remove the tcp soil carefully with a chunkol, then break open the run to the end of the probe. Pass the probe in again and proceed as before until the termitarium is reached. To find the tunnel or to pick it up again should it be lost, Ihave found it a good plan to cut a trench round the tree attacked or the spot where the run was lost. This trench should be to 302 The Supplement to the Tropical Agriculturist the depth of the wator level, say two feet, and should be examined the next day when it will often be found that the termites have made their way across by means of a mud casing, thus determining the direction of attack. It isa tedious matter at the best to follow up these tunnels and it is on this account that I have found it EXPEDIENT TO EXAMINE ALL TIMBER which L know to be likely to contain termitaria before resorting to this means thereby saving much time and expense. At first I gave rewards for the Queens and have collected in this way upwards of seventy un- doubted specimens, but liind that by this method the coolies waste much of their time in break- ing up every smaller piece of the termitaria in order to find the Queen colls, When a log or root containing the termitarium has been discovered and destroyed and the sround around it dug up it may safely be con- cluded that the Queen has perished with therest of the individuals, Usually itisonly necessary to trace up the runs in the case of anest occurring in a buried stump or root, The first field I systematically cleared of all timber five months ago has since shown no sign of the pest. This field was planted with Ram- bong about six years ago, it was allowed to lapse into bluker and was interplanted with para in 1906, The only remaining timber was Kumpas of which there was a considerable quantity. Tho attack on both Para and Rambong trees was particularly virulent in this block but has now entirely ceased. ‘As Mr Pratt very truly says, owing to the cryp- tic habits of termites itis very difficult to de- termine when a tree is attacked until it falls down; but during the wet season in October, November, December and January the termites frequently make their appearance above ground and this fact I think should be taken advantage of, by marking in some way all the trees on which the termites make their appearance, for even if they cannot be attended to at once, one would at Yeast know where to look for them in the future. T am afraid that some planters are lulled into a sense of security by the fact that none of their young trees have been attacked; it would be well worth their while to make asearch for 7. ges- troi in the timber lying in clearings andif found, take steps to eradicate the pest, for although trees may not. be attacked now, or perhaps for a year or two to come, they will be attacked sooner or later if 7. gestroiis present. J have not found a single tree attacked so far in my forest clearings, but I know that 7. ges- troi is present. On the other hand in reclaimed land, owing to the decay of most of the timber, 7’. gestroc has wandered forth in search of fresh fields and pastures new it has made its presence evident by attacking young rubber trees. On Fourore Orearines.—In these again the importance of discovering the forest trees most favoured by 7’. gestroi is evident. I cannot speak from practical experience, but the obvious course to p ursue would be tocut down all trees known to harbour 7. gestroi and allow them to dry for as long a period as possible, prior to the felling of the land. Many of these trees would be then destroyed in the burn and those which remained could be burnt out by piling over them the surrounding timber, This would of course enhance the cost of clearing perhaps by $10 or even $20 per acre, a small con- sideration in comparison to the damage that may be effected by T. gestroi. Further advantages of more thorough clearing would be less likelihood of vacancies caused by Fomes semitostus anda saving in the cost of weeding, in fact of every other work carried on in the clearing together with easier and consequently more efficient supervision....... DRAINS AS AFrscTiING TeRMES GEstroI.—I have not in asingle instance found the runs of ter- mites crossing a sub-soil drain, excepting by means of a fallen log or wooden bridge. It fol- lows, therefore, that the more frequent the drains, the more circumscribed wili be the attack of the termites, provided that iron or concrete bridges are used instead of wooden ones and that all timber lying across drains be removed. The mound termites, 7. Walayanus, and T. carbonarius seem to prefer the edge of adrain for the construction of their termitaria but ges- troi apparently considers the suitability of timber only and not that of soil in choosing its home. When nearing adrain the 7. gestrov runs are usually found at a greater depth than elsewhere. This is no doubt due to the facility with which the termites are able to penetrate the soil which has become freer owing to good drainage. ... . INSECTICIDrS vor THE HRADICATION or TERMUES GESTROT, To anyone who has followed up a 7. gestroi tunnel, ramifying as it does sometimes for hun- dreds of feet, or has seen the interior of a termi- tarium with its myriads of individuals, the utter futility of attempting to eradicate the pest by means Of insecticides must be apparent, but insecticides will be found useful in killing the comparatively few individuals which continue their attack for some time after their termi- tarium is destroyed. I see that the custom of applying lime to the tree attacked still continues on some estates. This is utterly useless as a preventative, or even as a means of keeping the termites in check; but it is useful as a means of marking the trees attacked. CroraLARIA AND GREEN MANORES AS AFFECTING T. GuEstTRot. Crotalaria is undoubtedly of great advantage asagreen manure, but it has yet to be proved if itis 2a means of cheapening the cost of weed- ing. Thereare two objections to it which can however be overcome. Firstly, the difficulty which is experienced in eradicating 7’. gestroi and Fomes semitostus, will be enormously increased by the fact that all timber is hidden by growth rendering it neces- sary to closely inspect each rubber tree and to search about amongst the crotalaria for timber containing 7. gestroi. This can be overcome by first eradicating the pest and then planting green manure. Secondly when the green mauure is eventually killed out by shade, the rubber tree will experience a shock from their custo mary supply of nitrogen bring cut off. This can y and Magazine of the Ceylon Agricullural Society. be obviated by interplanting with leguminous trees, such as Albezzia moluccana. These trees together with others of the leguminosa have been GROWN WITH GREAT BENEFIT TO TEA AND COFFEE IN CEYLON and elsewhere for at least twenty-five years— such growths as Crotalaria mimosa, etc., being utterly unsuited to this class of cultivation. In conclusion there are no grounds for the alarmist view of the 7. gestrot pest, though it is imperative that it should be taken in hand at once and dealt with very thoroughly, andalthough the initial cost may be heavy, it will be more than justified by the subsequent saving in expen- diture, on keeping the pest in check, to say nothing of the saving in loss of trees. .

The disease appears to be more widespread than I thought when I wrote in the last November number. A com- mon mistake is cutting the trenches too broad —this demands extra and unnecessary labour, and the excessive quantity of earth talon cut covers the inner area round the diseased tree so much that the turning-over does not go deep enough, Where circumstances do not allow of the outer trenches being made, the adjacent row of trees should be examined from time to time. Crotalaria striata is also attacked by a root fungus, but up to the present I have not been able to infect healthy Para rubber from diseased Crotalaria, Planters who have sown Crotalaria should watch their plants carefully and should immediately notify the Department of Agriculture if any die or even look unhealthy. Itis extremely important to know tho extent of this Crotalaria disease and if Para is immuno to it. The symptoms of diseased Crotalaria are much the same as those described for root disease in Para but of course not so easily noticed.—W. J.

DesiccatED Coconut—Cacao—anpb Frpre. The recent drought, combined with the de- structive cyclone not long ago, led to a shorter output of coconuts, with theresult that desic- cated coconut went up in prico by leaps and bounds, Local exporters did not anticipate that an easier tone would prevail for some time to come; but, contrary to these expectations, we learn that the ‘‘fine” grade now has a market value of 15% cents per lb. No causeis attributed for this decline; but it is conjectured that the financial or trade position of America is largely responsible for the unexpected change. During the past year the shipments of de- siccated coconut to Australia had materially declined—from 1,236,767 1b. in 1907 to 951,626 1b. in 1908. Whether this is—or is not—owing to the establishment of a costly desiccating factory, the only one in Australia, or perhaps outside Ceylon, it would be interesting tu know. This factory is at Paramatta where as ‘Messrs. Megeitts, Ltd.,” Messrs. Thompson, Fraser, Ram- say, Proprietary Ltd., who are the principal shareholders, are carrying on a flourishing busi- ness. Thecozonuts, which are principally ime ported from the Solomon Islands, Fiji, are said to possess a thicker kernel than the Ceylon nuts, but their productive capability of the desiccated material falls far short of the local nuts. For instance a ton of desiccated coco- nut would require nearly 6 tons of Fiji nuts, whereas the same quantity can be produced by about 43 tons of Ceylon nuts. It is only lately that, through the instrumentality of the firm above-named, a reduction was obtained from the Shipping Conference of the rate of freight ; but unless the market for the local nuts declines, it is thought in some quarters that it will some day be itnpossible tor the Ceylon to compete against the Fiji product, This year to date, however, the exports to Australia are 50 per cent. above last year to the same date ! The late season's cocoa crops have been very unsatisfactory, for the supplles have been un- usually short, and the beans are much smaller than the average size. Climate conditions are no doubt answerable to a great extent for these results; but at the same time an impetus is thereby given to producing centres in other parts of the world. The latest cabled advices from London intimate that the market there for the local product has advanced. The absence of rain has contributed in a laree measure to an abnormally big output of mattress fibre during the present season. Millers have therefore, had the opportunity of drying their stuff 304 The Supplement to the Tropical Agriculturist with the result that there is a proportionately larger quantity available locally. Despite the advanced market in regard to copra and coco- nuts, fibre has maintained a practically pheno- menal local market value. The latest trans- actions have been at R1'60 per cwt. in bundles delivered at wharf; but should the weather change in any marked degree, millers will be placed ata disadvantage inasmuch as they will not have the same facilities for drying. The failure of the N.-H. monsoon may, perhaps, be counterbalanced by the advent of an earlier South-West. In this latter event, the transport of fibre from the mills outside Colombo to the Metropolis will be greatly hampered and there is every probability of the market showing a decided advance in the near future. For the present Millers hesitate in making forward contracts, HOW VANILLA IS GROWN iN HAWAII. Process OF PoLLENATING THE BLOSSOMS AND CurING THE BEANS—PROFITABLE BUSINESS, The growing of the Vanilla bean of commerce has attained considerable importance in Hawaii, where a number of successful small plantations have been producing for a number of years. Jared G Smith, late director of the United States Agricultural Experiment Station in Honolulu, gives the following interesting des- cription of the growing of vanilla in his book, “Agriculture in Hawaii’ :— ‘‘The vanilla bean is the cured and fermented fruit of a climbing orchid. The finished pods are very dark brown or black, glossy, somewhat wrinkled on the surface, from five to eight inches long and about as thick as a lead pencil. The vanilla extract of commerce is simply an alco- holic extract. “The vanilla plant is grown either on a trellis or is planted at the base of a tree so that it can clamber up the trunk. Any soil is suitable, provided the drainageis good. It grows well ip regions or abundant rainfall onthe Kona (south or southwest) side of the islands. A mean temperature of 65 to 75 deg. gives good results. “The plants are propagated from cuttings, which are simply lengths of the vine itself, from two to six feet long. The length of the cutting has some relation to flower produc- tion, the longer ones yielding flowers in a shorter period. The leaves are cut from the lower end of the cutting and the stripped portion of the stalk is buried horizontally under two or three inches of soil and rotting leaves. The upper end of the cutting is fastened to the trunk of the supporting tree to which it soon becomes tightly attached by its aérial roots. “The vanilla plant begins to flower during its second or third year and continues flower pro- duction until seven or eight years old. Culti- vation consists in keeping down the weeds and underbrush in the plantation. “The vanilla plant only bears pods when the flowers are hand pollenated. This is a delicate operation not difficult) to learn. Any one who attempts if becomes quickly proficient so that a good many flowers can be pollenated in the course ofa day, The pod matures in from six to eight months, becoming hard, thick and greenish-yellow. They are gathered before ripe. “The curing process is a somewhat compli- cated one. After gathering, the green pods are spread out aud exposed to the air for 24 hours, being roughly assorted into grades according to size. After being graded, the pods are sweated between the folds of woollen blankets exposed. to the heat of direct sunshine. During the per- iod of fermentation the pods turn dark brown,, become soft and leathery and sweat freely. The pods are manipulated for several days until the proper degree of colour and aroma have developed. After the fermentation they are dried in the sun for a few hours and fin- atly in cloth covered trays in the shade with gentle heat. When fully dried, that is when the pods no longer lose weight, but are still moist and pliable to the touch, they are packed tightly in tin boxes and are again manipulated in bulk for one or two months. When completely cured, the pods are sorted to size and colour, tied in bundles and these packages packed in. tin-lined boxes. which are soldered when full. ‘¢The yield per acre in Hawali'has been esti- mated at about 13,000 pods, producing about 120 pounds of finished vanilla beans fully cured and ready for tho market. ‘“‘The industry is a very profitable one for persons having sufficient means who will give this industry their personal supervision. The price of the vanilla bean depends as much upon the outward appearance of the finished product as upon its actual quality as indicated by aroma and flavour. Care is therefore necessary at every stage in the growth and fermentation of the crop. ‘* Five acres of vanilla in bearing should yield from $400 to {500 worth of beans per acre per annum after the third year. There are vanilla plantations in the Kona district on the-island of Hawaii and in the Kona district of Oahu near Honolulu, Much land is still available which is entirely suitable for the cultivation of this crop,” —Hawaii Promotion Committee Press News. RUBBER IN MALAYA IN 19908. ACREAGE AND PROSPECTS., Go,090 Acres Opened Last Year. Mr. Carruthers, in conversation with a con- temporary, said that according to the returns he has obtained, there were, on December 81st last, 37,000,009 rubber trees growing in the Malaya Peninsula, including the new territory, Kelantan, with upwards of 2,000 acres already in rubber. 60,000 acres were opened in 1908—40,000 were in the Federated Malay States—tho total being rather more than in 1907. INCREASE IN YIELD, The yield per tree for 1908 worked out at one ounce more than in 1907, viz: 1 lb. 14 oz. per tree. The average increase of girth per annum, Mr, Carruthers put (at a guess) ab rather Jess than four inches, because rubber growing in lalang came along very slowly. He was gladito and Magazine uf the Ceylon Agricultural Society. Say green manuring was now being widely and successfully adopted, though in one or two instances strange orders had come out from home to cut out passion flower, &c., though suc- cessfully established. It is interesting to state that, before leaving Kuala Lumpur, Mr Carruthers applied for 180 acres of lalang in Perak Stateto make practical tests as an estate proprietor of the methods he advocates. The terms are the usual ones for lalang land—one cent per acre per annum for the first seven years and one dollar per acre per annum afterwards. The place will be locked after by Mr Carruthers’ cousin, who is on an estate about 14 mileaway. Mr Carruthers in- tends to give one spraying of arsenite of soda and then turn off and immediately plant three varieties of useful cover to complete the killing out of lalang, viz., passion flower ; abrus preca- torius (distinguished by its well-known red seed with black top); and a new vigna which Mr Carruthers came across just before leaving and which appeared to promise well. Mr Carruthersconsiders the rubber industry to be of a permanent character, and, although after lalang the rubber is usually a little slower in growth for the first few years, he did not mind whether it took eight years instead of six in coming to the remunerative stage, consid- ering the small cost of the planting. COCONUT PLANTING IN FIJI. Referring to his review (Fujz Times, Nov. 25th, 1908) of cur Coconut Planters’ Manual, Mr. R L Holmes of Bua, Fiji, writes under date, December 14th ;— -“T have been a coconut planter for nearly 40 years and have often used strong language when referring to the shameful neglect of the autho- rities and settlers on Vitilevu comprising fully half of Fiji. And from end to end of that great island the coconut trees suffer from what you will name ‘the so-called leaf disease,’ that never kills trees, and requires only culti- vation and suitable localities—in fact, common- sense to make them flourish. I hope what I have now set forth may do some good, and thanks to you largely if it does.” From the review we quote :— One of the chief copra buyers in the group assured me that he learned from Home letters, that Fiji copra ranks the lowest ot any others in the English market, which means that the oil therefrom is very inferior. It is not hard to see the reason why, viz., the large quantity of bad copra sold by the natives, and accepted by upcountry buyers and mer- chants. Bought and sold at avery low price, itis thrown onto the heap of better class, mixed with it, and all shipped together to Kurope. Grossly unfair to planters who supply a first class article, as it lowers the value of the whole. Can the Government not stepin? Appoint an In- spector, and throw the rubbish into the sea, Natives would soon change matters by selling only good copra. I see continually, copra offered for sale by natives, abomi- nable rubbish exposed alternately to rain and sunshine, until it becomes rotten. Ifthey do not put sand into it like the Sinhalese, they often pour sea water on it in bulk, which increases the weight without mildewing the copra. It is a duty Government owe planters to see to this at once. Again, if it pays better to make and sell oil here, why not direct and assist coconut planters in this respect ? We see in the above, that in Ceylon there are over 2,000 oil mills, big and little ; in Fiji, not one! A big mill in Suva or Levuka would raise the price of copra immensely, and the honest planter would get a fair price for his produce. 39 305 “Again we want very badly, small hand machines for pulping and hulling coffee, For many years I have pre- pared coffee from a small plot of about 100 trees. Lately, with the help of a dozen Fijians, mostly children, I collected a big sack full, slowly pulped it, as formerly described, washed and dried it, and turned out avery good sample, 1 got Ist prize for some Liberian coffee at the recent Show in Suva; but it does not pay, and about half the crop I left on the trees torot. These are a few of the many things in which Government could assist us planters. Some day perhaps the Planters’ Association and the Agricultural Board may wake up and attend to something besides bana- nas, the culture of which is confined to the neighbourhood of Suva, Rewa, Navua and Nadi.” COCONUTS IN CEYLON. The following is from the first annual report of the Lowcountry Products Association of Ceylon :— Kstimated acreage in the lowcountry within the scope of this Association :— Coconut Palm «+ 700,000 at R500 R350,000,000 Arecanuts .. 50,000 at 200 10,000,0..0 Cinnamon - 45,000 at 250 11,250,(.00 Citronella -. 40,000 at 250 10,000,000 Tobacco : -» 1,000at 300 3 0,000 Minor Products, Pippen Nacnet: & a 1,000 at 150 150,000 Total .- 837,000 R381,7C0,000 Your Committee venture to state that the total capitalised aggregate value of the products mentioned above (apart from the value of area under paddy) is greater than the capital value of area under tea, rubber, cocoa, which can claim a total planted area of 660,000 acres, In comparing the relative value of the coco- nut industry or products of the coconut palm a very materid4l fact requires special comment, viz., the very large proportion of the products which is utilised in the Colony itself for edible purposes and in the form of oil for cooking and lighting in plumbago mines and poonac for cattle. The amount utilised in this manner may easily be represented as the yield of not less than one- third the area under cultivation in an average year and the value of this is not shownand can- not be in the export trade ofthe island. Apart from value itis important to realise the benefit which this industry confers on the dietary of the population. It is a well-known fact and one that has been insisted upon year after year by the Registrar-General in his reports on vital sta- tistics of the Island that the death-rate of the Negombo and Chilaw districts is the lowest in the Island, in spite of malaria. The liberal use of the coconut as part of the food of the people in those districts, and the steady high wage which they command through the industry, are undoubtedly responsible for the happy result indicated in the vital statistics. CULTIVATION OF THE Coconut PALM. It is regrettable that the rainfall during the year was adverse to the coconut planters in more ways than one. The prolonged drought affected the trees to a great extent. In the Puttalam and northern section of Katugampola Hatpattu a few hundred trees on estate plantations were killed. In and around Chilaw several hundred trees were seriously affected. The absence of rain rendered manuring either inexpedient or impossible which will result in a further shor- tage of crops. The prolonged drought and the failure of both monsoons affected new clearing work and young plantations very adversely. 306 In addition to this the outbreak of malaria during the last two months of the year rendered nearly 90 per cent. of the estate labourers unfit for work weeks together, in the Kurunegala, Chilaw. and Negombo districts. In the more progressive districts it is a grati- fying feature that the application of artificial manure and the systematic cultivation of land is being carried on more and more as the ad- vantages resulting become manifest. During the jast two years experiments with the growing of crotalaria having proved useful a very large ex- gent of land is now under this for green manure. MR. J. B. CARRUTHERS. IMPRESSIONS OF CHANGES IN CEYLON. In an interview an Observer representa- tive had with Mr. J. B. CArrutuers, Director of Agriculture in the Malay States, who is now gomg home to represent the Malay States at the Darwin Centenary at Cambridge, and later will proceed to Trinidad, to be Assistant Director of Agriculture, the first question asked had reference to the changes which had_ struck Carruthers in Ceylon since his !ast visit. iy, CARRUTHERS—Said that when he was last hero they were only just beginning to think that rubber was a future possibility. Now it was ait absolutely ascertained certainty. The rub- ber industry was on quite a different footing and it was only now a question of:solving the problem of the most profitable ways of cultiva- ting it. That had affected tea and the whole thing seemed rather more prosperous, ‘The tea industry was itself more prosperous and every- thing seemed more prosperous in the planting line. He had not really seen very much of Ceylon. He went up. to the Gangaroowa Ex- periment Station. That was beginning to add to knowledge and it was getting into shape, and becoming a useful sort of Tex Book for Tropical Agriculture. THe NorktHway SYSTEM. The patent thing of Northway’s interested him, Without having paid his 200 dollars he seems to have found out the main principles of the thing and it seemed to him very hkely to be, not revolutionary, buta very sound ad- dition to their experimental knowledge on the question of the extraction of rubber. What changes did you notice at Peradeniya, Mr Carruthers ? I donotreally know. The changes are for the better. The building done is a great im- provement, Their housing is a great advance. They were cribbed, and cabined, and confined in httle laboratories and now they have fine places to work in. The Gangaroowa laboratory has been built since [ was there. The gardens seem to be just as beautiful as ever or rather more so. Alltraces of the Rubber exhibition seem to have beenswept away. (Laughing.) It is about three yearsand nine months since I was here last. I passed through in May. Were you present at the Experiment Stations Committee meeting ? The Supplement to the Tropical Agriculturist No. I just waited to meet all the members all of whom were friends of mine but I didn’t stay to the discussion. I heard of everything they were going to talk about. Thegreen manuring question was one of the chief matters. Some of the plots are most interesting, nearly every plant that can be conceived to be useful is to be seen there. Then they have been working at tlfése extraction questions, oils from grass, citronella oils and other oils, the most profit- able grass and all that sort of thing. The most interesting thing about the station is that it was about 7 or 8 years ago 90 per cent. diseased with cocoa canker and if it had been in ordi- nary hands it would have been abandoned, but there is now about 2 per cent. of canker and the place is giving handsome and profitable crops. It can always be quoted as a fine instance of what scientific tackling of a disease will do. It has justified its existence if only for that and it has added to knowledge in many other directions. In answer to a final enquiry Mr Carruthers said that the total acreage under rubber now inthe Malay States was 240,000acres. 60,000 were planted last year as against some 55,000 the year before. There were 37,000,000 trees in the Penin- sula, There were 112.000 acres of coconuts. COCGNUTS IN B. E. AFRICA. The value of the coconut plantations on the coast, says areport from British East Africa, has depreciated, owing to the damage caused by beetles and to the custom which prevails among ~ the natives of tapping the flowers, from which they obtain “tembo,” a native intoxicating beverage which is largely consumed. The Gov- ernment entomologist is investigating the life history of the beetle with a view to devising means for its extermination. There has latterly been a distinct movement to revive the coconut industry on the coast, wherein past years it proved a large source of income to the Arabs before they lost the services of a number of their slaves.—Trade Journat. {I presume the “native intoxicating bever- age” isour old friend arrack. It only shows how the gocd things the Creator gives us are abused and how the abuse recoils on our own heads.—Cor"., ] THE COCONUT OIL MILL IN KUALA SELANGOR. The one and only sight at Kuala Selangor is the Oil Mill on the opposite side of the river. Visitors embark in a sampan from a shelving stone jetty, if it can be socalled, which might be vastly improved. At low water the embark- ing ina sampan is an acrobatic feet. The Oil Mill is well worth a visit. The first process is to convert the nut into copra by means of dryers, the copra is then passed through various machines which grind it toa small powder. This powder is then placed in fold over canvas covers—about half a kerosine oil tin going to one cover—and then placed in the hydraulic press. This press takes quite a number of these canvas bundles in its different compartments, and Magazine of the Ceylon Agricultural Society. The oil is then squeezed out into a bank below from which itis sucked up to pass through a mechanical cleaner or—if there is no hurry—to large tanks where impurities sink to the bottom leaving the clear white oil to be drawn off from the top. The place is full of all scrts of machinery and another huge boiler has just been erected to enable the company to keep the Mill going without the otherwise necessary stops for boiler cleaning. Coir making machinery has recently been erected, so that every part of the coconut can be used except the milk, Now that the company has its own steamer there is no diffi— culty in getting a full supply of nuts. The com- pany, too, is fortunate in its manager, Mr. Darby, who is particularly well qualified in every wey to make the Mill a success.—Malay Mait, an. 25 —_— SANDY SOILS AND THEIR IMPROVEMENT. —_——_— The improvement of sandy soils is a subject of wide interest, and any mgans that would tend towards effecting such improvement will be wel- comed as much in this island as elsewhere, since there are large areas of land that are charac- terised by soils composed chiefly of silica, Acom- mon objection to most soils.is the disproportion- ate preponderance of one ingredient over the rest, whether sand, clay orhumus, The moans of im- proving soils must, of necessity, differ, inasmuch as the preponderating ingredient invests a soil with properties that have to be specially reck- oned with. Thus the treatment of a heavy clay will materially differ from that ofa loose sand and of both from that of a soil made up almost en- tirely of organic matter. The New Jersey Ex- periment Station recently published an account of experiments made to improve sandy soils, and a consideration of the results should be pro- titable to all who have similar problems to face, A fact that has to be recognised at the outset is that sandy svils are, from their very nature, unable to furnish as much plant food or moisture to growing crops as those of a clayey nature : further, that the coarseness of sandy soils prevents them from retaining either food or water when given to them, All who have had anything to do with sandy soils will readily admit that manures are easily washed downwards into the sub-soi] by rains, while dry weather soon robs them of moisture. for successful cultivation, such soil needs a tolerably well-distributed rainfall, a fairly com- pact sub-soil, and a water-table near enough to the surface for cultivated plants to draw upon the moisture below. In very coarse soils of this nature, capillary power is so limited that they are unable to replenish from below the loss of moisture by evaporation. Again, the openness of light sandy soils, by admitting air freely, accelerates the chemical and bacterio- logical changes going on within them, so that plant food is made more quickly available; pometimes, indeed, too quickly—so that organic Indeed, 307 matter in the soil becomes exhausted sooner than is desirable, Well-aérated soils, there- fore, favour bacterial activity, but the loss of water from them interferes with the action of soil organisms. To improve sandy soils, tharefore, it is ne- cessary to reduce their too open texture :— (1) by methods of tillage, such as cultivating and rolling ; (2) by application of fine-grained materials or substances readily pulverised, such as clay or loam ; (3) by the addition of large quantities of humus-forming material, such as green crops or ‘* long ” manure, A sufficiency of humus prevents too ready access of air and increases the moisture-holding capacity of a soil. Although sandy soils are naturally poor in plant food, this does not pre- vent the possibility of their improvement. Phos- phoric acid and potash can be supplied at a comparatively small cost, and nitrogen pro- vided by means of green manures or animal manures. The last-mentioned are not indispen- sable and often too expensive ;in some cases they are the means of introducing weeds or fungus diseases. Green manuring is particularly effective on account of the relatively groater need for nitrogen and humus in light soils, and the facility with which green crops are converted into available plant food. The selection of these will depend pvreatly on local conditions, the number to select from being fortunately large. A mistake that is common is to expect green crops to flourish even though there is an entire absence of phosphoric acid, potash and lime in the soil. That is not rea- sonable, and where these ingredients are de- ficient, the deficiency must be made good. If this is done, and thereis a fair rainfall, the prospects of utilising green manuresin the way suggested, are good. With the supplying of humus to a sandy soil, and the increase of its water-holding capacity, a uniform bacterial development and a more uniform supply of available plant food will be assured ; indeed, the . growth of bacteria is directly encouraged in the presence of organic matter and moisture, The nitrogen-fixing bacteria of lezuminous plants find very favourable conditions in sandy soils, and that for the following reasons :— (a) The small proportion of available nitro- gen in them. (6) The free circulation of air which favours the formation of nodules, (c) The frequent renewal of air which enables the bacteria to supply themselves with the ele- ments of the atmosphere. It has been found that in compact soils, nodules on roots are limited and found near the surface, whereas in sandy soils they are well distributed and occur at greater depths, There is an impression abroal that a leguini- nous crop which succeeds in one place is bound to succeed in . another, which is not so, auda crop new to a given locality may entirely fail to develop nodules because the proper organisiag 308 are not present inthe soil. The bacteria-pro- ducing nodules in different crops (say, soy bean and cow pea) are not identical, and each legu-- minous plant may be said to haveits own organism. The importation of earth from a field where a nitrogen-ygatherer flourishes generally suflices to start the formation of nodules on the roots. Lime, while not required to any extent by sandy soils, pats te the formation of humus, which helps to fix phosphoric acid and potash, Lime, therefore, though necessary,. should be only sparingly given—so that it may not unduly encourage the development of soil bacteria which hasten decomposition of organic matter. Ground unburnt lime is to be preferred to burnt and slaked lime. A dressing of half-a-ton of round oyster shells will generally be found suf- ficient ona sandy soil. Lime, asis well-known, is appreciated by most leguminous crops. In the New Jersey experiment the land (a distinctly sandy soil), while under preparation, was given 1,000 lb. lime, 320 lb. acid phosphate, 100 lb. ground bone, 160 1b. muriate of potash, 150 lb. of dried blood per acre. The returns showed a gradual and marked increase, and it is considered reasonable to assume that by sys- tematic cropping and fertilising, uncultivated and unproductive lands may be profitably uti- lised, particularly for the production of fodder crops with which dairy-farming might be profit- ably associated. It would, indeed, appear that sandy soils have a great future before them and that some day they are destined to be the scene of intelligent and remunerative cultivation. i Aden, Jan. 23.—I have just had an interview with Mr. Stewart J. McCall, on the deck of the steamer ‘‘ Kronprinz,”’ as he was about to leave Aden yesterday, en route for Nyassaland, where he takes over the duties of Director of Agricul- .ture. There are few men who have had such a varied experience in cotton-growing as Mr. McCall, and his name will be well remembered by many officials of the Federal Department in Washington and also in the cotton-growing States of America, through which he passed on a professional tour last summer. Prior to his arrival at Aden, Mr. McCall had passed three months in Ceylon, anverliaane the prospects for cotton-growing in that island, and at the re- quest of the Government wrote up an extensive report on the subject, which is to be published. Harty EXPERIMENTS. He informed me that attempts to grow cotton in Ceylon in small quantities had been made for many years; but they had not been wholly suc- cessiul, owing to the fact that the most tavour- able seasons for planting had not been observed, and other essentials with regard to local con- ditions had been omitted. He considered the prospects for cotton-growing in Ceylon decidedly good, but it was necessary to plant in the dry season with adequate and regulated irrigation, The Supplement to the Tropical Agriculturist He said the most favourable land was situated in the northern provinces, where nearly four million acres were available and suitable for this purpose, under irrigation. At present, prac- tically nothing is being done with the land in question, so that the suggested schemes, if carried into effect, would not in any way inter- fere with the present products of Ceylon. ‘ “What are the prospects of a commercial success being attained?” I inquired. ‘¢ These are in every way excellent,” Mr Mce- Call replied, ‘‘as transport is cheap to and from Colombo, beside which a good Government railway penetrates the suggested provinces. Naturally, considerable care would initially have to be taken as regards the variety of cotton introduced, and I consider that which has proved the greatest sucess in Egypt is most suitable, samples of which sent to Manchester as far back as 1905 were valued at ninepence a pound, being well up tothe average of Egyptian cotton for that year. Experiments have been conducted throughout the three intervening years, and there is now a considerable quantity of cotton- seed of this particular type available, partly acclimatised, at the Government experimental station in Ceylon.” MARGIN OF PROFIT. ‘“* The matter is under the consideration of the British Cotton Growers’ Association at Man- chester, besides attracting the attention of local planters. Tho cost of production should net average more than sixpence a pound, so that the - margin of profit is a good one.” The fact that Mr McCall previously held the appointment of Lecturer on Agriculture at the Agricultural College in Cairo, Egpyt, places him in aposition to speak authoritatively on Egyp- tian cotton.—New York Herald, Feb. 7.

Batticaloa, March Ist. Drar Siz,—In your paper recently { notice a correspendent writing about the destruction of illuk grass on Mr. Nicholas’s estates. Would you be so kind as to get the information from Mr. Nicholas or your correspondent how to get rid of the illuk, as we have a great quantity here aud would like to know how it is destroyed ? —Yours faithfully, JUHN COTTON. Mr. G. T. Nicaouas’s METHODS. Golua Pokuna, Katunayaka, March 10th. Dear Sir,—Absence from home has delayed my responding to the call made on me, in your issue of the 4th instant, in reference to Mr. John Cotton’s letter, asking for information as to how to get rid of Illuk grass. Just three years ago (5th March, 1906), the Hon. Mr. J. Ferguson, c.M.G., read a paper, at the meeting of the Board of Agriculture, on ‘‘Tiluk or Lalang Grass: a tropical weed pest, with measures for combating it,’’ supplemen- ting his paper with one by myself ‘‘Ona Simple and Inexpensive Method of Suppressing and Exterminating Illuk over large areas in Coconut Plantations.” These, with other connected papers, were published in full in the May 1906 number The Supplement to the Tropical A griculturist . ofthe “Tropical Agriculturist” and I refer Mr. Cotton tothe magazine for full details of my methods and results. The idea of growing certain plants to keep down Illuk Grass appears to have ‘‘ caught on” for we now read of /'assiflora fetida being used in the Malay States for suppressing the pest. But, in my opinion, this plant is less suitable than the Madu vel (Sinh.) which is of a more robust habit of growth; if the latter be grown along with the shrub known to the Sinhalese as Pupulu, the Illuk issoon got under, The tendrils of the Madu vine attach them- selves to the blades of [lluk and draw them down, whilethe thick close growth of the Pupula shrub completely shades the ground and helps to choke out tho weed grass. I shall be glad to give Mr. Cotton any further information on this subject and also to send him seeds of the above-mentioned plants, 1f he will communicate direct with me, Treatment with ‘‘ Arsenite of Soda” is said to have proved very successful in experiments made in Selangor, but [ have never tried it as [ have been quite satisfied with the efficacy of my , own method which is devoid of any element of danger. ‘‘Arsenite of Soda” being very poisonous, care must be taken that no cattle eat the treated grass. The method of preparation and application of the solution is as follows :—‘‘2°88 lb. of washing soda are dissolved in 3 gallons of water and boiled; then 2 lb of white arsenic are slowly stirred in, the liquid being kept boiling till all the arsenic is dissolved. It is then diluted to 20 gallons as a stock solution,” ‘Two pints of this are diluted with five gallons of water and this is sprayed on the grass, or it can be put on by means ofa cloth, one end of which dips in a trough on wheels containing the solution, the other trailing on the grass and kept open by means of an iron rod.” ‘‘The grass can be first burned off. When new shoots are 8” to 9” long the wet cloth is drawn over them which kills the shoots in 48 hours. This is repeated each time new shoots appear, the object being to exhaust the roots of all starchy matters and so kill the plants en- tirely.’’— Yours faithfully, GERALD T. NICHOLAS. RUBBER NOTES.

This is one of the finest and rarest of Anthuriums. {It bears large ovate-oblong leaves, which when young have a striking, glossy metallic appearance. A distin- guishing characteristic of the plant is the curiously waved surfaces of the leaves, which is imparted by the sunk and arched veins. The plant is «a native of Colombia, where it was first discovered in 1877. Being of slow growth, and difficult to propagate, it is rarely seen in living collections. H. &. MACMILLAN.

After care- Pi ie ful consideration it was decided by THE EXPERIMENT STATION, Government that the title ‘‘ Experiment PERADENIY A. Station, Peradeniya,’ was the one best A revised list of the Plots on the Experiment ‘Station, Peradeniya, by R. H. Lock: Circulars and Agricultural Journal of the Royal Botanic Gardens, Ceylon, Vol. IV., No. 18. The writer of this note does not pro- pose to criticise his own publication. The appearance of this circular, which consists almost exclusively of a compila- tion from the work of others, is merely taken as the text for a few remarks on the history and position, functions and work of this agricultural institution. The writer, however, feels justified in remarking that he has had rather special opportunities of becoming acquainted with his subject, having had facilities for closely examining the whole estate during the two first years of its occupa- tion by the Ceylon Government; whilst during the past year he has had the advantage of revisiting it after a con- siderable interval and noting the marked improvements and extensions of work which have been carried out. The historic estate of Gangaruwa, first opened in coffee by Sir Edward Barnes, and more recently cultivated in cacao, coconuts and other products, was taken over by the Government of Ceylon on May Ist, 1902, in order to be developed as an experimental plantation for the suited to describe the position and func- tions of this institution. To this ques- tion of a name we venture to direct Special attention, because it is one upon which there exists some misapprehension and the station is often miscalled, both in the press and in conversation. At the outset practically the whole attention of the small staff had to be devoted to a single large experiment, which occupied the greater part of the cultivated area for some years, and can be said to have only recently been com- pleted. In 1902, the Cacao canker, then rampant in many parts of Ceylon, had thoroughly established itself on Ganga- ruwa estate, so that practically all the cacao trees over 150 acres were affected by this scourge, and the crop had sunk toa figure which represented a dead loss to the estate. Vigorous measures were immediately undertaken, an account of which is to be found in the Reports of the Controller of the Experiment Station and of the Government Mycologist for 1902 and the years immediately following. As the direct result of these measures the cacao canker may now be said to be under complete control, whilst the con- dition and cropping power of the plots under experiment may be said to be as 314 good as they could possibly be—if the nature of the varieties and the way they were originally planted are taken into consideration. It may safely be asserted that this first large experiment has turned out an unqualified success, and that the instruction afforded by it has not been without value to the cacao industry of Ceylon. We may next allude to the important series of experiments relating to the manuring of old cacao, and representing the first thorough investigation of the effect of the repeated application of various fertilisers to a permanent crop in the tropics. It is too early, as yet, to dogmatize upon the 1esult of these experiments, but from their very nature it is impossible that they should ulti- mately tail to yield information of first-rate value. The celebrated experi- ments at Rothamsted have now been in existence for over sixty years, and although they deal with the manuring of an annual crop, some of the original trials are still being continued. There is, no doubt, that such experiments must be continued over a considerable series of years before the conclusions drawn from them can be_ regarded as beyond the reach of criticism. It is therefore useless to be impatient of results, and worse than useless to jump to hasty conclusions from the result of afew years’ work; but itis anticipated that in another five years or so we shall] begin to know something about the manuring of old cacao. Meanwhile, a long series of minor experiments have been carried out, and these alone would be sufficient amply to justify the exis- tence of the Experiment Station during the first few years of its being. EHxperi- ments have been made, or are being made, upon the following products among others—attended in every case with information of value to those interested in them—Cacao, Tea, Rubber (including Hevea, Castilloa, Funtumia, Ceara and the new varieties of Manic¢obar), Coco- nuts, Paddy, Arecanuts, Citronella and Lemon grasses, Tobacco, Maize and various leguminous plants, as wellas a number of others of lesser interest. Criticisms have reached us at various times because some of our experiments have turned out to be failures. To criti- cise an experiment and say it ought uever to have been attempted because it has not turned outa success, shows not only a want of appreciation of the essen- tial natuce of an experiment, but also a misapprehension of the chief aim and object of an Experiment Station. We conceive it to be one of the chief functions of those responsible for the working of such a station to make [ApRin, 1909, mistakes in order that others may avoid - them. Itis their business to try forms of cultivation so speculative that people of moderate capital are not justified in attempting them for themselves. Such forms of cultivation will often turn out to be impracticable, but even if one out of many proves to be a success, the infor- mation gained will make up for many failures by its value to the community at large. An allied, but more serious, mistake into which visitors have some- times fallen is to suppose that because some particular crop is being tried upon the Experiment Station, it is thereby guaranteed asa paying form of culti- vation, A reference to our preceding remarks will show the reason why this is not by any means the case. Reports on all such crops are published in due course, and it is by these that we expect the public to be guided. On the other hand, visitors who have eyes to see, and who are able to refrain from jumping to conclusious upon a cursory examination of incomplete experiments, will find a great deal to interest them on the Experiment Station—whatever their own particular line of agriculture may be— and all such visitors are very welcome.

The price of refined camphor has drop- ped in Japan to 1s. 53d. per Ib., with the alleged object of killing the com- petition of synthetic camphor which has partially succeeded, as it is said that the principal makers in Germany have for the present ceased manufacturing. If true there is no reason for a further decline in the price cf camphor. The chief countries using camphor are British India and the Straits Settle- ments, where the consumption is chiefly due to the use of camphor in the manu- facture of fumigating candles for ritual- istic purposes and of medicinal prepar- ations; Hurope and America, where it is mainly employed in the manufacture of celluloid, ; The Japanese Government intends monopolising the trade in camphor seed and may stop exportation of seed al- APRIL, 1909.] together, seedsmen having already been cautioned against selling large quantities of camphor seed abroad, The decline in pricesis said to be main- ly due to the increased production of Natural Camphor in China, and of Syn- thetic Camphor in Germany, also of ‘“*Monol” and other substitutes. In the South of China camphor trees are abun- dant almost everywhere and the ex- port is rapidly increasing. The Chinese Camphor is not as pure as the Japanese, owing to cruder methods of distillation. In Formosa the camphor production was limited to the Western, Northern and Southern parts of the Island, the regions inhabited by the Aborigines having scarcely been touched. Recently a Government expert dis- eovered a forest rich in camphor to the South of Arisan, and a favourable deve- lopment of the Formosan Camphor in- dustry is anticipated from this fact. The Japanese have commenced the cultivation of camphor in the Korean Island, Quelpart, and intend introducing there either the Borneo Camphor tree, or the rapidly-growing composite Blumea balsamifera. Successful experiments in the culti- vation of camphor have recently been made in parts of Upper Burma, close to the China Province of Yunnan. ‘The Government of Assam have also made successful cultivation experiments in the plant of Watijain. Numerous enquiries have now been made to this Department for the best methods of distillation of camphor from the leaves, and it is evident that the areas planted in India, Malay States, &c., are now coming into bearing. A paper by Giglioli, “Le Camfora Italiana, Rome, 1998,” has now appeared in print, and is said tosupply detailed in- formation on the production and the price fluctuation of Synthetic Camphor; the presence, production and commercial con- ditions of the Natural product; botan- ical, geographical and_ climatological notes on the camphor tree; production and purification of camphor and the state of the trade and prices of camphor cil. He recommends the cultivation in every part of Italy except the interior, and the cooler northern provinces ; and drought and inclement winds must be avoided. The average camphor content in fresh leaves grown in Italy is given as from 1:2 to 1°38 per cent. and about 0'5 per cent. of oil. The average yield obtained by distilling by the Japanese method is 1 per cent. of pure camphor. Riviere, a French Scientist, in the Journal d’Agriculture tropicale 8 (1908) bis? i 815 129 is sceptical about the cultivation of camphor and distilling the leaves, and does not think itcan compete with cam- phor from the natural forests of old trees or with the synthetic camphor now being put on the market—a new factory for which is being established in Finland to develop a new process of Komppa. Cinnamon Oil, Ceylon.—The chemical properties are given of Ceylon Cinnamon oil as bright yellow, feeble acid re- action : dois 1024 to 1040 aa, slightly to the Jeft. Soluble in every proportion of .90 per cent. alcohol: test for nitric acid ; Aldehyde content 65 to 75 per cent. (determined with Sodium bisulphate). Lemon Grass Oil.--The price of this oil fell from 9d. per oz. in 1905-06 to 2d. in 1908, owing to large imports from West Indies accumulating in Lon- don; but these are now to a great extent cleared and such large supplies are not liable to be repeated so quickly in future. The oil content of the individual parts of Andropogon citratus have been investigated by A. W. K. de Jong, who found that the leaves contained most of the oil, the largest quantity being in the latest formed leaf, decreasing as the leaf ages. The citrate content of the oil becomes slightly higher as the age of the leaf increases, viz., from 77 to 79 per cent. in the youngest to 83 per cent. in the oldest leaves. The sheathsalso contain oilbut less than the leaves themselves. The thick bulbous roots also contain from 0°5 to 0°35 per cent. of oil according to the age and their distillation is sug- gested, but the quality and citrate con- tent is not given. De Jong concludes that the plants should be cut when four or five leaves only have formed. In Cochin-China distillation experi- ments have been made which show that the grass contains much more oil in the dry than rainy season, and that the tip of the leaf to one-third of its length js more aromatic than the remaining two-thirds. Dried leaves, losing 70 per cent. of moisture, yielded 8 to 8°5 per cent. of oil, whilst fresh leaves yielded in the rainy season 2 per cent, and in the dry 5°b per cent.

K. B, 316 THE KLEMENTS OF PHILIPPINE AGRICULTURE. By E. B. CoPpELAND.* This is one of the first serious attempts to write an elementary text-book of Agriculture for use in tropical schools, and consequently requires serious con- sideration. The author recommends that the work be used in connection with a_ school garden, in which every boy should have a plot about 15 feet by 9, if necessary, rather than make the plots smaller; he would put two boys to each, as with small plots the importance of space is not properly understood, The student should map his plot carefully ; this, of course, is incidentally useful as a lesson in geography. His plants must be most carefully laid out in regular rows at exact intervals. Each student should keep a note-book in which the map is entered, and every detail about the growth and treatment of the plants, and these should be frequently overhauled by the teacher. After a general introductiou the book goes on to deal with the parts of plants, with the soil, with plants and their need * The World Book Company, Yorkers-on-Hudson, New York and Manila, P. I. [APRIL, 1909. of light, water, &c. Though somewhat too condensed, this part should be easily enough understood by a boy of say 15, and to younger children than this we would not teach agriculture. After this follow chavters on the actual crops, maize, coffee, abaca, &c. It is difficult to criticise an elementary pioneer work like this; but, in general our impression isthat, while a good work so far as it goes, itis too much con- densed, and will require great ampli- fication, with detailed practical demon- stration, by a good teacher; and itis in the provision of such teachers that the difficulty lies in tropical agriculture.

At the beginning of a new year in the life of The India Rubber World it always has seemed to us appropriate to engage somewhat in retrospect. The recounting of accomplished progress in any industry is of interest not only in itself, but as indicating lines of possible future development. The nine- te en years which have elapsed since the initial issue of this journal have been fruitful in invention and progress in many ways, and in to other industry, perhaps, more than in rubbder and the allied interests. We feel certain that the last word has not been said in the development of rubber interests, and look ‘forward to chronicling every year much more news of importance in this trade. To eliminate from the rubber trade to-day all that has been developed in it within the past nineteen years would leave some very wide gaps—nearly everything in the way of vehicle tyres, the greater part of the insulated wire manufacture, air-break hose, hose for pneumatic tool work, the rubber-cored golf-ball, and an immense number and variety of minor articles of rubber, together with the new processes and apparatus which have been perfected for their production. The rubber world, so to speak, has been greatly broadened in those nine- teen years. The opening up of forest rubber areas in Africa and in the upper Amazon regions has alone proved of vast importance tothe industry, while the iatroduction of rubber culture has still further increased the world’s supply of raw material. Scarcely less important has been the great improve- ment in reclaiming rubber and the increase in the volume of this product. The growth in the extent of the output of the rubber factory has involved not only a large increase in consumption at home, but the sale of important quanti- ties in countries not consumers of rub- ber before. We cannot better sum up the stitu- ation, perhaps, than by referring to the International Rubber and Allied Trades Exhibition, just closed in London, as an epitome of progress in rubber; to have omitted from its catalogue all that represented development during the past two decades would have left little more than a skeleton. We regard this exhibition as epoch-making, and by comparing few rubber exhibitions with it will best be measured the growth of the trade. It is of interest to note that seldom has rubber been utilized to an impor- tant extent for the purpose without con- tinuing to be so utilized. Hence every new application means a permanent addition to the catalogue of the uses of rubber. To-day the possibility appears to exist of a great coming demand for rubber in aerial navigation—a demand which within the coming nineteen years may prove as important as the present demand for rubber in the tyre trade. We donot doubt that the most im- portant development in the next decade will relate to the production of crude rubber—in new fields and from new plants, as well asin the improved pre- paration of rubber in the field now ex- ploited. It isnot unlikely that within this period the culture of what now are regarded as minor rubber plants will become extensive in the temperate zone.—The India Rubber World, Vol. XXXIX., No.1, October, 1908. THE RUBBER EXHIBITION : SOME NOTABLE EXHIBITS AND MR. BAMBER’S PROCESSES. By Huspert L. TERRY. The main features of this Inter- national Rubber Exhibition have been dealt with by the Editor, and the obser- vations I am about to make refer entirely to the raw_rubber exhibits of Ceylon and British Malaya, which occupy two of the most prominent stands in the Hall. Stand is perhaps too plebean a term to use in connection with the ornate pavilion of Ceylon and the attractive native dwelling of Malaya, but its significance will not be misunder- stood. These two exhibits, along with the Dutch colonial exhibits, may, I think, be selected from the bulk of the show as of special, interest, embodying as they do the results up to date of the rubber planting industry—one of,the uewest departures in economic botany. In no way do I wish to belittle the interest attaching to exhibits of raw rubber from the forest—such as the splendid show made by the State of Amazonas. Native rubber, however, is not exactly a novelty, and as the object of the exhibition was declared by the President in his opening speech to be primarily educational, it is important to Gums, Resins, lay stress of the greatest novelties in so far as they have an important bearing upon the rubber interest generally. Both the Ceylon and the British Malaya stands contained samples of plantation rubber from the most import- ant of the numerous companies located in their respective districts, and it would probably prove more monotonous than instructive to refer to each of these separately, especially as the rubber in its various forms of sheet, block, crepe, worm, etc., is much the same as produced by each company. Botanical exhibits were numerous, and also photographs of general scenery and processes connected with the industry. Samples of such catch crops as indigo and tapioca were also to be seen, and mention should not be omitted of the model estate rubber factory at the Ceylon stand fitted up according to Mr. Kelway Bamber’s ideas of how the work of preparing | raw rubber for the HKuropean market should be carried out. It is, of course, noto- rious that the procedure on different estates varies considerably, which is not surprising, seeing the novelty of the whole busiuvess, and no doubt for some time to come we shall witness great divergencies of opinion, There is no doubt, however, that the planters will best serve their own interests if they endeavour to produce rubber of always the same quality, even of the same tint. This latter point may not really be of any importance, but it carries weight with the less enlightened manufacturer. The great complaint in manufacturing circles up to now has been about the want of uniformity in bulk lots of plantation rubber, and this is of course due to the different procedure adopted on the various estates, and also to the variable pro- cedure of any particular estate. In this respect, therefore, I consider that the detailed proposals made by Mr. Kelway Bamber for the coagulation and pre- paration of the rubber on exact and uniform lines form one of the most important topics brought to the notice of visitors to the exhibition. The varia- tion in the colour of the plantation Para from Ceylon and Malaya as shown in the numerous specimens on the stands is very striking, practically all shade from pure white through yellows and browns to black being represented. If Mr, Bamber’s process is generally adopted in the future, it will mean thata uniform product which is practically white will be produced, and that rubber manufac- turers will be able to order lots amount- ing to several tons with full confidence that the quality will be the same throughout. It would take up too much 318 , [Apriz, 1909, space to give Mr. Bamber’s proposals in anything like detail, but a summary of the main points may be attempted. It is important to make a daily testing of the latex from each field in order to determine when the proportion of rubber has fallen to the minimum paying quantity. Whatever method of tapping is employed, the trees should be marked in such a way that the bark will be removed systematically and no irregular patches left which cannot be tapped. The best angle is 45°, and this should be maintained by keeping the cuts perfectly parallel from start to finish, and not gradually making them more vertical towards the lower end. The knife must be kept perfectly sharp so as tocut and not tear the bark, and immediately after making the cut the channel should be moistened with a very dilute ammonia or formalin solution applied by means of a piece of cloth on a stick; this encourages the flow, delay- ing the coagulation, and the proportion of scrap rubber is reduced. Mr. Bamber advised the use of glass or stoneware cups in preference to sheet iron, as they are more readily cleaned. They are also to be washed before use in a dilute formalin solution made by mixing one part of the ordinary 40 per cent. solution of commerce with 40 parts of water. All the latex collected in the cups is to be strained through fine wire gauze into enamelled or wooden buckets, and on arrival at the factotyis again strained into large vats and sampled for its yield of rubber. With regard to the determination of the amount of web rubber per gallon, it may be remarked that unless the exact procedure is de- tailed, very variable results will be obtained by different operators, a very similar case being the approximate de- termination of gluten in flour. With regard to coagulation Mr. Bamber does not seem to favour mechanical methods except where the amount of latex to be treated is only small. His proposals are a high temperature and the use of well diluted acetic acid. Itis inthe coagulation that his most important suggestions arise. He has found that if the latex has steam passed into ituntil the temperature arises to 180° F., and is maintained at this heat for three hours, certain organic sub- stances of a proteid nature are destroyed, and the rubber subsequently precipitat- ed by acetic acid is quite white and maintains this colour after shipment. It is mentioned that a solution of wood creosote in spirit can be added during coagulation if desired. Presumably the Fo Apri, 1909,] doctors are not agreed as to the utility or otherwise of this addition of creosote. Samples of perfectly white rubber pre- pared by this oxydase-destroying process wereto be seen on both the Ceylon and Malaya stands, and it will be interesting to hear what the trade has to say about them. Mr. Bamber’s main contention is that uniformity in bulk will be secured, and, further, that the colourless rubber will be found of special use in the manu- facture of certain goods—such as teats, for example—the white colour not being affected by the vulcanization. With regard to the subsequent wash- ing and rolling processes it is advised after the first rolling to again immerse the rubber sheetin water at 180° F. to ensure complete destruction of the oxydase and the complete removal of all soluble matters on which bacteria and fungi grow. After this the rubber is allowed to contract naturally in cold water out of contact with the air. Mr. Bamber is against the too rapid drying of the rubber, and remarks that the 10to 15 per cent. of moisture in Brazilian Para is probably an advantage to it. Hedoes not seem to be enamoured of the vacuum drying process, and thinks that the vacuum process if used at all should only come after the natural drying in order to get the rubber quite dry for packing. The best method in his opinion is the use of perfectly dry air which can be obtained easily and economically by a plant of which a working model was shown at the Ceylon stand. It involves the use of a refri- gerating plant and a system of pipes which strike one as decidedly ingenious, and for the purpose to be achieved to be devised on sound scientific lines.—IJndia Rubber World, Vol. XXXIX., No. 1, October, 1908. THE NEW MANIHOTS. By Dr. C, E. WATERHOUSE. During the last two years and es- pecially this year great interest has been aroused in some new species of Manihot rubber trees which from all accounts are far superior to Manihot glaziovii, and which should be of special interest to the rubber growers of Hawaii, from the fact that the Manihot glaziovii or Ceara rub- ber tree grows and yields so well in Hawaii. Some of the reasons why, if these species do as well as the Ceara, it will be well worth the while of the rubber growers of Hawaii to pay particular attention to these species in future plant- ings will be forthcoming later in this paper, 319 Saps and EFxudations, The export of rubber from the State of Bahia has increased more than ten fold within six years, having risen from 100 tons in 1900 of very inferior rubber to over 1,100 tons in 1906 of a very superior grade of rubber. This led to an investigation of the sources of this new supply and the discovery that, in- stead of the low grade of Mangebeira as formerly gathered, the suvply came mainly from the three new and very valuable varieties :— 1. Manihot dichotoma or Jequie Mani- coba ; 2, Manihot heptaphylla or Sao Francis- co Manicgoba ; 8. Manihot piauhyensis or Piauhy Manicoba. These varieties were so named by Dr. Ule, so well known as an authority on the classification of different srecies of rubber trees, and who visited the State of Bahia and neighbouring States in 1906 to look into the sources of this supply. Until six years ago Manihot glaziovii was considered the only rubber-yielding species of its genus (though there were 82 species recorded which will soon be 100 when all those discovered are described). It was only in the early part of 1906 that even the Kew Gardens, the birth- place, so to speak, of the rubber industry of the far East and always on the lookout for new species of rubber, was aware of the existence of rubber- yielding trees closely related to the comonly cultivated Manihot glaziovit. All these species, from all accounts, not only yield considerably more latex than the Ceara, but what is of very much more importance to Hawaii is, the amount which one man can collect is much greater (in other words the cost of collection is considerably less). This isa most important item here owing to the high price paid for labour, in fact the point upon which the whole success of the rubber industry in Hawaii hinges. A notable fact in this connection, one which will appeal to any one who has had any experience in tapping the Ceara is thatin these new varieties, in shedding the bark, longitudinal slits are formed and the membranous bark peels off in more or less verticle rows. This allows its removal much more easily and there- fore cheaply, than is the case with the Ceara. These varieties of Manihot, like the Manihot glaziovui or Ceara, have a very dry habitat, However, just as we find here in Hawaii that the Ceara does better in wet localities, so with these varieties the same may be true, That the Ceara does better here where it is Gums, Resins, wet I think there is no doubt. I have myself ina little experiment station of my own tried watering some plants and leaving others in the same soil unwater- ed, and the watered plants far out- stripped those unwatered, and seemed to have as much more latex, though the trees are still too young to draw conclusions from as to yield. In regard to these three varieties: (1) Manihot Dichotoma. The seeds of this variety are much larger than those of the Ceara. Germin- ation takes place in two to three weeks if unfiled, the shell being much softer than in the case of the Ceara. The soil upon which this tree flourishes is variously described as red clay and red loam. The bark of this tree is thinner and more delicate than that of the Ceara, (2) and (8) Manihot Heptaphylla and Manihot Piauhyensis. The seeds of these two varieties can hardly be distinguished from each other; they are only a little larger than Ceara seeds. They do not germinate nearly as well as in the case of the Manihot dichotoma. These two varie- ties in the region around Bahia thrive in a sandy soil, growing largely on sandstone mountains. Both varieties do not grow as tall and are smaller than the Manihot dichotoma and in- clined to branch low. They are not affected by the wind so much as Ceara, probably on account’ of being smaller and more low lying. This also affects the methods of tapping as explained later. The foliage is cnaracteristically green and fresh-looking. Methods of Planting.—There are a number of plantations around Bahia, some of which are now three or four years old. They are planted for the most part 1,000 trees to the acre. This close planting has been atopted because the trees are planted in a dry locality, and itis claimed that if not planted so closely, or say 200 to the acre, the ground would be baked so hard and dry that the trees would dwindle and die. Also the trees are considerably smaller than other varieties, and consequently need less room. Methods of Tapping.—In the case of the Manihot dichotoma the bark of the trunk is tapped and an instrument curv- ed at the tipis used. The herring bone or a single cut isused, Cups are used to receive the latex. The latex coagulates quickly on exposure to air but appar- ently not too quickly to prevent its flowing down into the cup’s well. Water is sometimes used in thecups to prevent too rapid coagulation. 320 [APRIL, 1909, In the case of the Manihot piauhyensis and Manihot heptaphylla, the shorter trunk and somewhat thinner bark than the Manihot dichotoma are not suitable for cutting, and by this method yield little latex. 1:39) -0°35 3.

Quarantines were instituted and a general effort was made to interest the local officials and communities in preventing the spread of animal diseases. The work was more or less unsettled atthe beginning as the lines of procedure had to be worked out in the provinces. Some changes were necessary from time to time during the first three years. This formative period of the work has long since passed, and it is now thoroughly organised with definite plans which are certain to give results if persistently followed. The first thing done was to inspect imported cattle to determine whether or not they had infective diseases on arrival. The records show clearly that agreat many of them did bring such diseases, especially from China. The next step was to inspect those cattle being shipped from ports of entry, especially Manila, to the provinces, and determine whether or not they left these ports in a healthy condition. It was found that many of them carried the diseases to the provinces. It was also found that where diseases prevailed in the provinces they were spread extensively by local cattle trading. The result of all these studies and observations was to define the different lines of action which are known to be necessary in the suppression of the diseases. The first of these was to estab- lish a rigid inspection and-limit the movements of cattle by means of quaran- tine. The first effort in this direction was the enforcement of the veterinary section of the Sanitary Code of the City of Manila, which became _ effective, January 1, 1907. This law was held in suspension for some months, but in due course of time the quarantine of imported cattle exposed to infective diseases was undertaken. This led to immediate and strong opposition by certain local cattle dealers. They even questioned the integrity of the Govern- ment officials who had charge of enforc- ing the quarantine. All of this agita- tion led to a full discussion of the subject, which finally resulted in the passage of Act No. 1760 of the Philippine Commission on October 12, 1907. This in effect extended the quarantine to infected and exposed_animals through- out the Islands. Strong protests against all quaran- tines were constantly made on the round that liberal importation of cattle or draft purposes was necessary to replace those which had died from diseases in the provinces. It wasshown in the May Review that 90 per cent. of the cattle imported into the Islands 70 553 Live Stock, come to Manila, that70 per cent. of these are slaughtered in this city, and 80 per cent. of the remainder shipped to the provinces, are subsequently slaughtered in the towns near Manila. So this argument lost much of its foree. If it were not tor prejudice, seven pounds of meat out of every ten produced here by imported cattle, could as well be bought from cold storage. After considerable agitation, General Order No, 9 was issued April 30, 1908, Its main feature was to exclude cattle from the infected places throughout the Orient. This order met with strong opposition from the cattle dealers, and its enforcement was suspended on technical grounds. _General Order No. 10 was issued and provided a system of automatic limita- tion of shipments from infected places. It gave dealers time toship cattle which they claimed to have on hand and per- mitted three successive infected ship- ments to be landed, However, certain unscrupulous dealers began deliberately importing infected animals from differ- ent Chinese ports, changing when three shipments had been made from each. This was followed by the issuance of General Order No. 12 which put all ports on the same basis in so far as landing of infective shipments is concerned. Under these provisions when an infect- ed shipment of cattle arrives in Manila, the animals can be landed for immediate slaughter only. This order is the most important step . yet taken by the Government in prevent- ing the constant reinfection of different parts of these Islands with rinderpest and_ foot-and-mouth disease. It marks a distinct epoch in the history of the veterinary work which all thinking men who understand this problem will readily appreciate. The order in itself is not complete, in that it does not provide details for the cleaning and distinfection of ships, corrals, and other places from which the infection of these diseases is liable to spread. Anattempt has been made to remedy this by the codification of all general orders from No, 10 and including the rules and regulations for disinfecting. This constitutes General Order No, 13, published in this number of the Review, There are three more logical steps which the Government should, and no doubt will, take in due course of time. The first of these is to provide a means of handling infected shipments of cara- baos and selected breeding cattle which are intended for slaughter. This would be simple if there was an Island in Manila Live Stock. 554 Bay on which they could be_ landed. The questionis now under consideration, and efforts will be made to settle it as soon as possible. The second is to exclude entirely all shipments containing infected animals. This action is not absolutely essential now, as cattle can be landed under cer- tain restrictions and immediately slaugh- tered without spreading diseases, but the exclusion of infected shipments would deter importers from buying cattle at infected ports, and place a premium on importations free from the diseases which we have been fighting so many years. A shipment from an infected port, found to be free from disease on arrival and permitted to land is much more dangerous in spreading disease than the infected shipment land- ed for immediate slaughter only. The one is alive and in contact with native cattle, to which disease will spread if it develops, while the other is dead and beyond the possibility of spreading disease. The next will be the complete exclu- sion of allanimals from ports or places known to be infected. While this step is not justified at the present time, it will ultimately prove an absolute necessity. It can be done just as soon as it becomes ceitain that an abun- dant supply of cattle and carabao, to meet al) our demands. can be had from ports which are known to be free from diseases, and from which infected ship- ments will never come. The only sate course is to make sure that the animals of these Islands will have no chance to become infected, and the only certain way of guaranteeing them against the further invasion of infective animal diseases is to completely exclude all animals from all ports and countries in which infective diseases exist or are liable to prevail. CORNS ON HORSES’ FEET. (From the Agricultural News, Vol. VIII., No. 179, March 6, 1909.) A corn on the foot of a horse or a mule necessarily results in a certain degree of temporary lameness. If the proper method of treatment is adopted, however, the trouble can usually be got rid of in a comparatively short time, but it is important to remember that unskillful or ignorant treatment may readily increase the trouble so as to result in more serious lameness. The following sensible note on this subject is extracted from Hunting’s ‘Art of Horse-shoeing ’ :— A corn, be it remembered, is not a tumour or a growth; it is merely a bruise of the sensitive foot under the horn of the sole. It showsitself by staining the horn red, just asa bruise of the human body shows a staining of the skin above it. To ‘eut out acorn’ with the idea of removing it issimply an ignorant pro- ceeding. If a corn be slight, all that is necessary is to take off the pressure of the shoe, and this is assisted by removing a thin slice or two of horn at the part. When the injury is very great, matter may be formed under the horn, and, of course, must be let out by removal of the horn over it. Provided there is no reason to believe that matter has formed, a corn— 1.@., the bruised and discoloured horn— should not be dug out in the ruthless manner so commonly adopted. Cutting away all the horn of the sole at the heels leaves the wall without any sup- port. When the shoe rests upon the wall itis unable to sustian the weight without yielding, and thus an additional cause of irritation. and soreness is manu- factured, The excessive paring of corns is the chief reason of the difficulty of getting permanently rid of them. The simplest device for taking all © pressure of a cornis tocut off an inch and a half of the inner heel of the shoe. With the three-quarter shoe a horse will soon go sound, and his foot will then resume its healthy state. The saying ‘once acorn, always a corn’ is not true; but it is true that a bruised heel is tender and liable to bruise again, from very slight unevenness of pressure, for at least three months. All that is neces- sary is care in fitting, and abstention from removal of too much horn at the part. Of course, when the degree of lameness is such as to suggest that matter is formed, the horn must be cut away so as to afford an exit forit; but the majority of corns are detected long before the stage of suppuration has re- sulted from a bruise. DAIRY FARMING: WILL IT PAY IN CEYLON? By GEo. SCHRADER. (From the Ceylon Independent, 14th January, 1909.) By dairy farming I donot mean the manufacturing of butter and cheese, but the supplying of pure rich milk to large towns at a reasonable price. Everybody living in towns knows how [JUNE, 1909. JUNE, 1909,] almost impossible it is to get.a supply of pure rich milk ata reasonable price - owing to these difficulties the great pro- ortion of the people, who would prefer Fr esh milk, have to be satisfied with the preserved tinned stuff. Is it possible to supply the pure article so that the suppliers and the supplied will both be satisfied ? I maintain that it is possible to supply pure rich milk at 15 cents per bottle, at the same time yielding hand- some profits and quick returns without any great risk. The business man will say—‘‘ This is all very fine! but I want more tangible proof than this before I embark my capital.” Quite right! the object of this article is to prove this by facts and figures. I may say that Iam not convicting a theoretical story, but I am applying my knowledge and per- sonal experience gained elsewhere to what canbe feasibly done in Ceylon, A branch of the work of a large mixed farm I was managing in Australia was the supplying of milk to a town five miles away ; the portion of the country the farm was situated was not physi- eally suitable for dairying as the average rainfall was 14 inches per year, so that every bit of the food of the cows had to be grown under irrigation, which meant the great expense of pumping water by means of expensive machinery, ete. ; but still handsome profits were the result. Jt is a well-known fact among the farming world that thereisno branch of agri- culture that brings in better, safer and quicker returns than dairy farming, 7.e., the supplying of fresh milk to towns. Every other branch of farming is guided by the market, the prices of grain and fruit, rise and fall &e. ; while the cultivation of even our coconut palm, tea and rubber, etc., means the outlay of alarge amount of capital and the waiting for a good number of years for the first returns, whereas with dairying the price isa fixed price, and from the day the milk supply starts, the income starts. In Ceylon we have not the adverse circumstances I had to contend with, as most parts of the country havea splendid raintall averaging from 60 to 90 inches—the best spots are available for the pioneers to pick and choose; the market is unlimitted, so there is no neces- sity to go to the less favoured parts of the Island. Suppose, for example, a com- pany was started to supply Colombo with pure rich milk at a reasonable price. What eapital will it require? What would be the working expenses ? What would be the returns? What risk is there, and how should the farm be worked? I do notthink there is any necessity of labouring the subject of a market, as everybody knows that there 555 Live Stock. isat present an unlimited market for pure rich milk at a fair price, 12.e., cents 15 per bottle delivered. I estimate the eapital required at Rs. 40,000 for a dairy farm of forty cows—I estimate fairly high to be on the safe side—as per ac- count below :— Rs.

In examining these figures it will be found that I have provided liberally for every contingency, but even supposing the cows or theclearing of the land, etce., cost more than estimated, there is still left Rs, 7,168 out of the capital to meet any excess. The balance remaining will be tor working expenses—there is no necessity of any large reserve for working expenses, as it isonly for the first month money from the capital willbe required for that purpose—the monthly expenses will be Rs. 641°20, while the monthly income will be Rs. 1,620 for a month of thirty days. The handsome interest of 274 per cent. on the capital will no doubt be viewed with some suspicion, as too good to believe and impossible—examine and analyse the figures how you like and as you like, and you will come to the conclusion that it is feasible. It must be remembered that I have only taken the milk of thirty cows while forty cows form the herd. I have done so although in the actual working more than thirty cows will be milked daily for the 365 days of the year ; stillit must be remembered that cows require two months’ rest before they calve for the second milking, and also to allow for any deaths and for any cows that donot come up to the standard of two gallons of milk per day; also for the milk required to feed the young calves for the first three months of their life. Some might say that it is impos- sible to get two gallons of milk per day from a cow. I say from personal ex- perience and knowledge that it is pos- sible, it can be got, and it must be got, and that every cow that does not come up to that standard must be got rid of, and the sooner the better. (JUNE, 1909. There is another very valuable source of income that must not be forgotten. You will notice that I have valued twenty- five calves at Rs. 20 each, that is not to say that they must be Sold for that sum, and that the very ‘ow average of twenty-five that I have put down for safe calculation is to be the actual re- sults of the farm. In three years’ time there will bea splendid lot of young bulls and cows for sale, after reserving for the requirements of the farm, Sup- pose at the end of the first:three years we sold twenty-five head at Rs. 200, that would be Rs. 5,000,so0 that the yearly profits after the first three years will always be increased by the sale of sur- plus cattle. There is another source of profit that is worthy of attention, that of specialis ing to supply milk from special cows for the feeding of infants; for this pur- pose the milk can be supplied in special sealed bottles for 20 cents per bottle. For the successful working of this or any enterprise no source of profit ever so small must be thought too much trouble or not worthy of attention. The questionjof risk is a very important - one for the capitalist who embarks his money. The land-will not depreciate in value but will rather increase with the improvements, etc. The imported cows © (as they must be imported from Austra- lia) will stand the climate, especially if they are secured from’ semi-tropical regions ; we know that the Australian horses and the dairy cattle now in the Island are doing well. There is an unlimited market in Colombo for pure milk, especially at the price of 15 cents per bottle. The food can be easily grown if the manager understands his work. Cattle diseases—there should be no risk from any infectious diseases if the farm is scientifically managed, as danger from this source is generally due to bad, careless and unskilled management. How IS THE FARM TO BE WORKED. The allimportant question—as an accu- mulation of the best cows, the best land, the best utensils and implements, ete., will not produce the supply of lactic fluid that will be necessary to make the farm pay—is the management of the Farm: it must be properly worked by a capable man. It must be remembered that dairy farming isa science that requires deep study and plenty of experience—on the choice of the man who isto manage the farm entirely depends the success or failure of the undertaking. The people of Ceylon have not yet reached that point of understanding that Agriculture and planting industries require the services of qualified experienced men to get the JunR, 1909. } 5 best results. No man will dream of sending a clerk to take charge and work an engineering establishment, but at the same time he won’t think twice of send- ing the same clerk to manage a dairy farm, for he will argue—what is there to be done—its an easy life—only to see that che cows are milked, and to grow some grass for them and to see that the coolies give them food, and to get on to his lounger and smoke and read novels! That is all no doubt the clerk is capable of doing, but let us see what the duties are of the manager and what sort of an education and experience is necessary. “To see that the cows are properly milked,” the manager must be a properly trained and able milk man. (I wonder how many of those that are in charge of the present existing dairies know how to milk a cow or have ever tried.) To give the reason for this I cannot do better than quote from my notes on lectures on dairying that I received at the Aus- tralian Agricultural College I attended. Milking :—Itis of the greatest impor- tance that the introduction of bacteria into the milk should be prevented, and therefore the utmost cleanliness from the time the milker starts his work until the finish is absolutely essential if the best results are to be obtained. Before milking the hands should be thoroughly washed, also the cow’s belly, teats and udder if they are dirty ;in any case the dust should be brushed off them betore milking, orsome of it, with the always present bacteria, wil) be shaken off into the milk. The finger nails should be kept cut, and on no account should the hands be wetted by first milking into them—itisa dirty and useless habit. The cow-yard should be kept clean, it should not be cleaned just before milk- ing; or bacteria will find their way into the milk, to develop init flavours which may not be at all desirable. Milk should for this reason be taken from the cow- yard immediately. The teats diagonally opposite each other should be milked together, and not the teats on each side, as the former method increases the quantity of milk. The milking should be fairly fast as this increases the secretion, whereas slow milking reduces the quantity. The cow should be well stripped, as the last striplings are rich in fat; if any milk is left it is harmful to the supply. If the teats are sore, they should be handled with care, and after milking should be dressed with vaseline, ete., ete., ete.” A good milkman is able to milk ten average cows per hour. And to grow the grass for them? It is not such an easy matter as the indi- vidual who employed the clerk as manager thinks it is, The manager must Live Stock, understand the science and practice of preparing land and sowing the seed to procure a sufficient supply of grass or green fodder, or both, to feed forty-eight head of cows, bulls, and horses and also anumber of calves; he must know the number of tons of green fodder neces- sary, and how many acres will have to be cultivated to grow that number of tons. He must know to make the all- important ersilage, and the number of tons of ensilage necessary for feeding the cows during the dry months, and the number of acres that must be culti- vated to grow that number of tons of silage. No guess work will answer, as on the quality and quantity of the _ best- food depends the supply of milk. The manager must understand the science of feeding cows, as on it to a large extent depends the success of the under- taking, He must have some knowledge of veterinary science, as it would be out of the question and absurd to eall in a veterinary surgeon except in the case of any serious disorders. In fact, the manager must bea qualified and expe- rienced agriculturist and dairy farmer, if the dairy farm is to be a success. THe LAND.—The eighty acres of land that I estimated for must be procured out of Colombo but within a reasonable dis- tance of the city, t.e., within five to eight miles—the land must be carefully chosen as for situation, soil, and a plen- tiful and good supply of water. The entire eighty acres must be cleared, the stumps extracted, and fenced with a plain wire fence, passing the wires through holes bored in the posts, one barbed wire being nailed right on the top of the posts to prevent any jumping, it must be again sub-divided into four paddocks by means of more wire fencing, so that each paddock will be 20 acres in extent. TATA SERICULTURE BANGALORE, FARM AT By J. MOLLISON, M.R.A.C,, Inspector General of Agriculture in India —_—_— __ (From _ the Agricultural Journal of India, Vol. IV., Pt. I., January, 1909.) The late Mr. J. N. Tata established at Bangalore a small Sericulture Farm about 1898. It was started to help native rearers to control such diseases as affect silk-worms in India, and generally to give technical instruction in growing suitable kinds of mulberries, in rearing Live Stock. silk-worms, in reeling silk and preparing it for market. The little farm has answered these purposes admirably. Mr. Tata was familiar with Japanese methods. He considered them well suit- ed to India. He got for the supervision of his farm one Japanese Expert of the artisan class and another who knew sufficient English to act as interpreter. The fittings and reeling machinery for this small factory were mostly imported trom Japan. They are simple, durable, inexpensive and efficient. They were put up by the Japanese Artisan Expert elped by an Indian mistri and coolies. The Japanese Expert and his wife trained native girls of 10 to 14 years of age to do the reeling. I have repeatedly seen these girls at this work. The work was excellently done. I compare in the accompanying tabu- lated statement this work as done bya fieldman of my office after three months’ training at Bangalore, and the work done by the most expert reeler in the factory—a young girl. ay, GH i 3. | Be | Og & One a wo ‘a5 i apin} 44 iaes :| Sip! 4] sen ml | oat pe vo REELER. rs) g | g g 8 i g 9 os ae len iat oH o5 2 = a8 ees tape iaetecsl st eMedia cht gee H. .M.|H.

The 12 girls could, ina day, reel and re-reel about 2 lbs. silk, which was worthat the time of my last visit 17s. 6d. per pound in England. The value of the refuse silk was a considerable additional item of income, but was not estimated. The work of mulberry cultivation, rearing silk-worms, improving varieties of silk-worms by cross-breeding, detect- ing diseases by means of the microscope, preserving cocoons for seed and for 558 ate [Junn, 1909. _ hanking, pressing and packiug the silk for market, was thoroughly done. Ap- prentices were taken in free for instruc- tion. A three months’ course was re- quired for this purpose. Bush mulberries only were grown. The rainfall, average temperature and soil at Bangalore and generally through- out the Mysore plateau, appear to be well suited for the cultivation of bush mulberries. Those grown were three grafted Japanese varieties, one Italian variety and four others, probably Indian. The Japanese varieties cannot be propagated from cuttings; the others can, Plants of the Japanese varieties and cuttings of the other varieties can, I understand, be supplied to those in- terested in sericulture. The soil of the garden isa good deep dark red loam. Cuttings are first put in a nursery, and when they have rooted, are planted out 5 to 6 feet apart in each direction. In order to maintain a succession of young leaves throughout the year, the various plots are pruned in regular succession and irrigation given when required. Crude sewage and night-soil are used as manure with excellent results. Young leaves are required for the . larvee when newly hatched. If there is a fullsupply of these and of more mature leaves when the worms are larger, six or seven broods are reared in 12 months, Disease prevails extensively in Mysore. The following results were obtained from seed cocvons obtained locally :— (1) 615 moths laid eggs. (2) 114 of these moths were diseased as determined by miscroscopical ex- amination; therefore the eggs were destroyed. (8) The larvee from 501 batches of eggs hatched out. (4) These silk-worms ate 38,566 lbs. of green leaves. , (5) The leaves were obtained from 2°41 | acres of bush mulberry in full vigour of growth. (6) 270 lbs, of cocoons were obtained. At Bangalore, bush mulberry plan tations get worn out even with care ful pruning and cultivation in a few years. Young plantations to replace old should, therefoie, be formed from time to time. Rotaticn is desirable, A ten- acre area should prckably have 5 acres under plantaticns establis] cd for thice or four ycais cr liga, 61d 5 -@es urdera ruisey. ycourg pli ntaticus ard JUNE, 1909.] other crops. The whole should yield leaves sufficient for 6 or 7 broods in a year, each as large as that referred to above or larger. ‘Mr. Tata’s Expert recomiuends that the rearing house should be separate and at a distance from the buildings re- quired for storing cocoons and reeling with the object of avoiding the risk of communicating diseases. The rearing building should be constructed so that light and ventilation are fully secured ; a thatched roof and a verandah being desirable to keep the day and night temperatures fairly equable. Expensive construction is unnecessary. A mud floor does very well. There should be a plinth and, exclusive of verandah, a building 20ft. by 16 ft. is sufficient. The height to eaves should bel0 ft. The north verandah should be about 10 ft. wide and enclosed to form a room, If well lighted, the moths, as soon as they have laid their eggs, should be examined for disease under the microscope in this room, which should have no direct con- nection with the rearing house. The healthy eggs only should be kept. In the rearing house there should be three wooden stands each 5 feet high, 3 feet wide, each with three shelves, the lowest shelf should be 18 inches from the floor, These stands should be so placed that there is easy access to each. They are required to support the trays in which the silk-worms are fed. A brood from 600 batches of eggs can be ac- commodated in one tray when first hatched out, but requires about 150 trays when fully grown. The detailed cost of the fittings of the rearing house is :— Rs. As. 1, Three racks constructed of wooden frame and split bamboo shelves 30 0 2.

The hand-motive-power should be worked in the boiler house and also one blacksmith and carpentry work done. The whole building should be con- structed on a plinth with brick walls, 10 ft. high to eaves, with tiled roof. The reeling room should have a paved floor and arrangements for drainage, : Mud floors are suitable for the other rooms. The office will require ordinary furnish- ings with a vermin proof cupboard for storing seed cocoons. The furnishings are estimated to cost Rs. 50.

INDIAN WILD-FOWL. Tu INDIAN DucKS AND THEIR ALLIES. By EK. C. Stuart BAKER. (Review from Nature, January, 1909.) The enormous flocks in which many members of the duck tribe visit the plains of India during the cold season, coupled with the relatively large num- ber of species by which the group is there represented, affords ample justi- fication for the issue of this handsome and superbly illustrated volume. For the swarms of ducks, geese, swans, and mergansers naturally attract the atten- tion of a host of sportsmen, many of whom are anxious to identify the species of the birds which go to form their bag, and ascertain something about their natural history. « Neither is the book of less importance to the ornithologist— either professional or amateur—for Mr. Stuart Baker has much new matter to record concerning many of the species passed under view, while the thirty coloured plates—reproduced from sket- ches by Messrs. Cronvold, Lodge, and Keulemans—have a distinct scientific value of their own, altogether apart from their beauty as works of art. The origin of the book dates from 1896, when the author was asked to communi- cate a series of illustrated articles on Indian ducks to the Journal of the Bombay Natural History Society which should incorporate the numerous notes on the group published in the Indian scientific journals and sporting papers since the issue of Hume and Marshall’s well-known ‘“Game-birds of India.” These articles were commenced in the eleventh volume of the aforesaid serial, and the work now before us is a reprint of the series with such additions and emendations as were necessary to bring them up to date. 560 [Junn, 1909, Apart from the flamingoes, which are brigaded with the ducks under the general title of ‘‘Chenomorphe,” the author recognises no fewer than forty- three representatives of the group as visiting or permanently residing in India. He is, however, somewhat of a‘‘split- ter,” and certain of his species, asin the goose-section, would very probably be relegated to a lower grade by many naturalists. We are also ‘inclined to disagree with his views as to the multi- plication of generic groups. The divi- sion of the flamingoes into two genera, and likewise the splitting of the brent- geese into Rufibrenta and Branta, are examples of what appears to us totally unnecessary complication in this matter. The author has, however, taken Count Salvadore’s British Museum catalogue of the group as his guide, and he has adhered religiously to the classification therein adopted. We confess to a feel- ing that it would have been better to follow the late Dr. Blanford’s volume in the ‘Fauna of British India,” whereby greater simplicity would have been secured and at the same time some advance made towards uniformity in the names of Indian animals. In this connection we may note the urgent need of a proper table of contents at the com- mencement of the volume, the one which . does duty therefor being too absurd for words, two out of its half-dozen items being ‘‘ title-page” and ‘‘ contents,” while a third is “ Indian Ducks.” For a book which must be largely patronized by sportsmen (ifit is to make a profit), we also venture to think that too many technical terms, or definitions, are introduced without any sort of explanation. What, for instance, will the sportsman (or, for that matter, the amateur naturalist) make of the bald statement that the Chenomorphx are characterised by having the ‘palate desmognathous,” or what will he under- stand by the ‘‘neotropical region”? If such expressions are used at all, they ought to be adequately explained, but in our opinionthey are altogether out of place in a work of this nature, the pro- fessional naturalist does not want them, and the amateur and the sportsman do not understand them. In the place of the former a statement to the effect that the palate in the dry skull is of the closed or bridged type, and that the difference between the bridged and the open or slit type may be realised by comparing the skull of a duck with that of a fowl, would have been much more to the point, while as regards the latter it would have been infinitely better to use the ordinary names, South and Central America, in place of neotropical — region, = fk aioidhge cides, i iaad in? an, veil a amine cael ’ i _ JUNE, 1909.) With these exceptions—if it be added that the author has an extremely old- fashioned: and obsolete way of spelling Indian place-names—we have nothing but commendation for the volume before us, the species being clearly and care- fully described, with full and _ well- written notices of their distribution and habits. As Mr. Baker observes, the collection and collation of a vast amount 561 Inve Stock, of seattered information concerning the Indian Anatids 1enders it from the first possible to know the extent of our information on the subject, and to realise what gaps require filling up. The book should be in the library of every Indian sportsman, by whom it should be taken into camp in each winter’s sporting trip. a SCIENTIFIC AGRICULTURE. THE CONSERVATION OF SOIL MOISTURE AND ECONOMY IN THE USE OF IRRIGATION WATER. By EH. W,. HILGARD AND R. H. LOUGHBRIDGE. (From the University of California Agricultural Hauperiment Station Bulletin 121.) (Continued from pp. 456,) Basin Irrigation.—It will be noticed that this principle is practically the same as that of the basin irrigation of orchards, which was originally largely practised in California, but has now been mostly abandoned for furrow irri- gation. The latter has been almost universally adopted, partly because it requires a great deal less hand-labour, partly under the impression that the whole of the soil of the orchard is thus most thoroughly utilized; partly also because of the injuriovs effect upon trees produced at times by basin irri- gation. The explanation of such injurious effects is, essentially, that cold irrigation water depresses too much the temper- ature of the earth immediately around the roots, and thus hinders active vege- tation to an injurious extent, sometimes so as to bring about the dropping of the fruit. This, of course, is a very serious - objection, to obviate which it might be necessary to reservoir the water so as to allow it to warm before being applied to the trees. In furrow irrigation the amount of soil soaked with the water is so great that the latter is soon effec- tually warmed up, besides not coming in contact too intimately with the main roots of the tree, along which the water soaks very readily when applied to the trunk, thus affecting their temperature much more directly, Itis for the fruit- -grower to determine which consider- ation should prevailin a given case. 71 the water-supply be scant and warm, the most effectual use that can be made of it is toapply it immediately around the trunk of the tree, in a_ circular trench dug for the purpose. When, on the contrary, irrigation water is abun- dant and its temperature low, it. will be preferable to practise turrow irrigation, or pessibly even flooding. As to the more complete use of the soil under the latter two methods, it must be remem- bered that while this is the case in a horizontal direction, yet unless irriga- tion is practised rather sparingly under the furrow system, it may easily happen that the gain made horizontally is more than offset by a corresponding loss in the vertical penetration of the root-sys- tem. This is amply apparent in some of the irrigated orange groves of Southern California, where the fine roots of the trees fill the surface soil as do the roots of maize in a corn field of the Mississippi States ; so that the plough can hardly be run without turning them up and under. In these same orchards it will be observed, in digging down, that at a depth of afew feet the soil is too water-soaked to permit of the proper exercise of the root functions, and that the roots existing there are either in- active or diseased. ‘That in such cases abundant irrigation and abundant ferti- lization alone can maintain an orchard in bearing condition is a matter of course; and there can be no question that a great deal of the constant ery for the fertilization of orchards in the irrigated sections is due quite as much to the shallowness of rooting induced by over irrigation, as to any really neces- sary exhaustion of the land. When the roots are induced to come to and remain at the surface, within a surface layer of eighteen to twenty inches, it natur- ally becomes necessary to feed these roots abundantly, both with moisture and with plant food. This has natur- ally led to an over-estimate of the requirements of the trees in both respects. Had deep rooting been en- couraged at first, instead of over-stimu- lating the growth by surface fertiliza - Scientific Agriculture. tion and frequent irrigation, some delay ic bearing would ,have been amply compensated for by loss of current outlay for fertilizers, and less liability to injury from frequently unavoidable delay, or from inadequacy of irrigation. Conservation of Soil Moisture. —Along- side of economy in the use of irrigation water, the conservation of the moisture imparted to the soil either by rains or irrigation ismost important; critically so where irrigation is unavailable. Utilization of Winter Rains and Winter Irrigation.—However strong is the popular demand for storage of the winter rainfall and flood waters, too many do not appreciate the importance of the storage they can command with- out the use of reservoirs within their own soil mass. While there is a well- grounded objection to subjecting plough- ed land to the leaching action of the abundant raius in the humid region, no such objections hold in the case of lands lying within the limits of 20 to 25 inches of annual rainfall. Here the absorption of the winter rains should be favoured to the utmost, for the run-off is mostly a dead loss. Fall ploughing wherever the land is not naturally adequately absorbent, and is not there- by rendered liable to washing away, isa very effectual mode of utilizing the winter’s moisture to the utmost, so as to bring about the junction of the season’s moisture with that of the previous season, which is generally considered as being a condition precedent for crop production in dry years. The same of course holds true of winter irrigation; the frequent omission of which in presence of a plentiful water supply at that season isa prolific cause of avoid- able crop failures. Moistening the ground to a considerable depth by winter irri- gation is a very effective mode of pro- moting deep rooting, and will thus stand in lieu of later irrigations, which being’ more scant, tend to keep the roots near the surface. Knowledge of the Subsoil._It caunot be too strongly insisted upon that in our arid climate farmers should make themselves most thoroughly acquainted with their subsoil down the depth of at least four, but preferably six or eight feet, This knowledge, import- ant enough in the Hast, is doubly so here, since all root functions are and must be carried on at much greater depths. It is hardly excusable that a business man calling himself a farmer should omit the most elementary pre- caution of examining his subsoil before planting orchard or vineyard, and should at the end of five years find his trees a dead loss in consequence of an 562 unsuitable subsoil. Similarly, no irri- gator should be ignorant of the time or amount of water it takes to wet his soil to a certain depth. We have lately seen a whole community suffering from the visible decline of thift of its fruit trees, which occurred despite what was considered abundant irrigation; a.e., allowing the water to run for a given length of time, deemed to be suffi- cient. Yet on being called in to investi- gate the causes of the trouble, the station staff found that the irrigation water had failed to penetrate during the allotted time to any beneficial extent, so that the trees were, in the main, suffering from lack of wmois- ture—a fact that could have been verified by any one of the owners con- cerned, by simply boring or digging a hols or two. But no one had thought of doing so, and all kinds of myste- rious causes were conjectured to be at work in the suffering orchards. of oo bal Ae 5 a5, om ho Bam 62 x 2 Sp SEO oe ge 5 fm bon n 2a o = ° } Z = 15} D (e) 1 one 750 -- — — Baeetwo 1,000 - “6/3: O)jzs> 2 Bde 3 three 1,580 28/3 12/- 16/3 4 four 3,800 76/8 18/- — 58/3 This year the experiments were carried out with Wheat and Barley.

(From the Madras Agricultural Calendar, 1909.) This College is situated in the village of Thelungapalaiyam, about three miles west of the town of Coimbatore. The estate consists of 450 acres of land, of which 50 acres are good single crop wet lands, of the remainder about 3800 acres are available for cultivation, the rest being occupied with buildings and the compounds attached thereto. The dry lands are of various kinds, about 126 acres being black cotton soil of, how- ever, varying qualities. The red lands likewise vary from sandy to stiff clay loams. On the red lands there are ten wells which command most of the area, but there is a considerable area of unirri- gable land. It will be seen, therefore, that the lands are suitable for various crops and methods of cultivation. The institution is more or less divided into two sections, one devoted to the study of problems in Chemistry and Biology which arise in connection with Agriculture, and the other devoted to giving asound knowledge of the sciences upon which the Art of Agricultureis - es JUNE, 1909.] based, and of the principles which should govern any attempts to improve indigenous methods. Provision is made for the entry every year of twenty stu- dents, thus, usually, the students will be divided into three classes according to their year. The main building contains the neces- sary accommodation for the work of the Government Botanist and Agricul- tural Chemist, as well as class-rooms and laboratories for the instruction of the studentsin Chemistry, Biology, Physics, Agricultural Engineering, and _ the principles of Agriculture together with a library and reading-room for their use. The students will undergo instruction not only theoretical but also prac- tical in all the subjects of the course which includes a certain amount of Veterinary science sufficient for the treatment of ordinary cattle ailments. In Agriculture they will take part in all the ordinary farm operations such as ploughing, sowing, weeding, ete., and in their second and third years will each cultivate a plot of land themselves. It must be borne in mind, however, that agricultural practice is very largely determined by climatic condi- tions, therefore the practical agricul- ture followed will be that suited to Coimbatore, and operations carried out ina certain way at Coimbatore may require a considerable modifica- tion if introduced into another district. The object of the introduction given in the college is to enable men who have profited by it, to so modify their practices as to suit the conditions of any region to which they may go; in short, it should enable them to think out their own particular difficulties. The character of the soil again deter- mines very largely thekinds of imple- - ment which can be advantageously used, and during their course at the college students will have the opportunity of working, and of seeing worked, various implements designed to do certain work either more quickly or more efficiently than those in use at present, but they will not be expected to believe. that because an implement is either a success or a failure here, it must necessarily be soon their own lands; they must be prepared to make the experiments themselves if they see it is likely to succeed, and they should be enabled to suggest and put into practice modifica- tions which will render the implement suitable to their own conditions in case it is a failure. The college session begins on or about June 7th and ends on March 3lst. There are three terms ending respectively on 567 ® Miscellaneous. or about September 30th (Dasara) ; December 20th (Christmas); and March 3lst. At present no fees are charged, but students provide their own board and cook. There are hostels attached to the college for the accommodation of students, arranged in blocks of six, each block having a separate kitchen and dinning-room, thus, ‘students of differ- ent castes can be provided for. It will be found most economical for all the students of any one caste to join to- gether and have acook incommon. The cost of living will, of course, vary with the different tastes of different students and with the price of food-grains ; it may, however, be taken as being about Rs. 10 per month for vegetarians, An Athletic Club is attached to the college to which all students must belong. The sub- scription has been fixed at the lowest possible, viz., 4 annas per month. A reading-room has also been started by the students themselves for the purchase of papers, etc., to which the subscrip- tion has been fixed by the members at 4 annas per month. The question may arise: what is the use of attending the college, and what are the prospects of men who have passed through the course? To these questions it may be answered (1) as to prospects. Those who enquire about the prospects are, generally speaking, those who have not enough land themselves to enable them to make a sufficient living, and for such there are various Openings as managers of farms under zaminders and other large proprietors, and alarge farm like any other business always pays for good management. Several enquiries for men capable of managing such farms have been received at the college during the past year. As, however, the college is established for the benefit of Indian Agriculture, it is supposed that students will join in order to obtain knowledge to improve the yield of their own lands, and not merely in order to qualify for a post under Government ora zaminder. This leads to the answer to the other half of the question as tothe use of attending. In every large business, manufacturing or otherwise, there are usuaily two classes of men: the workers or labourers and the foremen or managers. The first of these classes is required to do the heavy and more or less mechanical work ; they arein many cases not requir- ed to be men of any_great mental capa- eity. The second class is composed of men who have brains and know how to use them for the benefit of the business, they guide the energies of the workers in the path which will lead to the best results, Itisthe latter class that wil Miscellaneous: gain most benefit in attending the Agricultural College, In too many instances an owner of a small area contents himself with letting his land to a cultivator, often of inferior mental capacity, and with receiving a share of the produce at harvest; whereas, if he used his superior brain power in direct- ing his labourers, he would very pro- bably obtain a larger return from the land. HEREDITY. By R. H. Lock. & The children of men are like their parents ;soare the children of animals and plants. The time is not so very remote when this was the sole definition which could be given to the term here- dity ;and information as tothe nature of this mysterious process was neither sought nor found. Simple as the above statement may seem, there is yet a valuable truth embodied in it. Our ancestors were endowed with powers of belief which enabled them to accept as true the most exaggerated assertions with regard to unlikeness between parents and their children. Among other remarkable manifestations of faith they believed that an animal might be the offspring of a plant or vice versa, as in the case of the celebrated barnacle goose. This was a tree described and illustrated by a famous savant of the Renaissance. The fruits of the tree were barnacles, and when ripe they opened and from eacha young bird emerged. The tree grew by the margin of the sea, greatly to the convenience of the geese, which fell immediately into the water and swam merrily away- Such a method of generation, if it were actually to occur, would offer a notable exception to the ordinary course of heredity. Every rule has its excep- tions, however, and it does not become an honestly inquiring mind to deny the possibility of even so remarkable an occurrence as the birth of the barnacle goose. Still anyone with a competent knowledge of the comparative structures of a goose, a tree, anda barnacle would require, like Huxley, considerable evi- dence before accepting the statement thata bird actually came into being in this way. The actual amount of evidence which would be required is a little difficult to estimate. No sane man would nowadays accept the evidence of his own eyes in sucha case; nor would the testimony of twelve good men and true approach the required standard of verification. 568 ~ A universal belief, however exag- gerated, has very often some grain of truth concealed init, and.we may seek the kernel of these extraordinary stories in the fact that the children, whether of men or of plants, are never exactly like their parents. In some cases indeed they are very different, though usually partaking of the racialor specific type to which the parent belongs. The fact that a man has two separate parents who are not identical effectually disposes of any possibility of his exactly resembling both of them. He might indeed exactly resemble his father, but itis a matter of common experience that fathers and sons are always distin- guishable. Most people on the other hand show some points of resemblance to both their parents. A _ child may have its mother’s eyes, and may take after its father in the colour or texture of its hair, whilst its nose may be the very image of that to be seen in a family portrait of its great-grandfather. If we reflect upon the details of any particular case, -we shall very soon realise how great a number of separate points go to make up the complete hereditary endow- ment of the individual. When we thus remember the great number of separate features of resem- - blance to one parent or the other which may be exhibited in any particular case, we seeat once the great inconvenience of treating individual people as units in heredity. Butitisonly quite recently that anyone has ventured to adopt a different method. The new method consists in regarding the individual animal or plantas being builtup of a number of separate factors, comparable with the different kinds of stones with ~ which a house may be constructed. These factors correspond in a general way with the various features and characteristics of the creature, and they are inherited quite independently of one another. : The first point, then, which is to be emphasised in any account of modern ideas about heredity is that which con- cerns the existence of unit characters. It is no mere metaphor when we speak of the separate attributes of an organism. But itis quite a recent discovery that we can in effect take an animal or plant to pieces and deal separately with the inheritance of its separate parts. which are separately inherited so much as certain definite attributes or charac-- teristics of these. Thus to take an ex- ample, in the case of the domestic guinea- pig, @ kind of animal in which heredity has already been some what fully studied, the sort of characters which can be [Junn, 1909 It is not, however, separate limbs or organs — “ae 5s + — > te Jong, 1909. dealt with separately are the colour of the fur, whether black, brown, or white ; and the distribution of these colours, whether uniform or in patches; the nature of the hair, whether long or short, and its quality whether smooth or curly. We have here no less than five pairs of attributes all characteristic of a single organ, namely the fur of the guinea-pig; these attributes being: (1) the presence or absence of a_ black pigment ; (2) the presence or absence of a brown pigment—in the absence of both these pigments the coat appears white— (8) the distribution of these pigments, whether uniform or not; (4) length or shortness; and (5) curliness or smooth- ness. Itis found that these attributes may occur in all possible combinations with one another—impossible combin- ations being represented by the associ- ation of two members of the same pair, for instance the hair cannot be at the same time black and white. But we may have long curly black hair, or short strait white hair, and many other combi- nations. More than this, each of these attributes is inherited perfectly inde- pendently of all the others. The black- ness may be derived from one parent, in which the hair was perhaps short, and length from the other parent the colour of whose hair may have been white. The fact that the phenomena of here- dity have been found to be amenable to definite experiment, depends entirely upon the existence of definite unit charac- ters such as these. The young guinea- pig may take after one parent in colour and after the other in the length of its hair, whilst it may possibly exhibit a third character, for instance curliness of the hair, which was shown by neither of its parents, but which was perhaps visi- ble in one or more of its grandparents. But we are already in a position to speak much more definitely than this concerning the precise manner of trans- mission of unit characters from parents | to offspring. Since every individual is complete in itself, each parent must eontribute to its offspring one complete set of these factors. Every child, there- fore, is provided with a doubie set of factors, half derived from its father and half from its mother; and every charac- ter or feature which the child exhibits depends upon the presence of a pair of factors, one member of the pair being paternal, and the other maternal, in origin. We might expect from this description that every characteristic of the off- spring would be simply the mean of the corresponding characters of the two parents, since the contribution of each parent to that character is equal. But 72 560 Miscellaneous this is not by any means always the case. In some instances indeed the influence of the two parental factors is about equal, and asa result the offspring shows an intermediate character. But in other cases one factor may beso much stronger than the other that the character of one parent is almost exactly reproduced, whilst that of the other remains entirely in abeyance. In other cases again, although one of the factors is stronger than the other, the weaker factor is still able to make its influence felt to some extent. In illustration we will consider a case in which one factor is so powerful as to render the other entirely invisible or recessive. The case is that of a cross between a black and a white strain of mice. A pure black mouse is to be mated with a pure white one. Into each of the offspring arising from this mating there enters something representing blackness and something representing whiteness. These representative some- things we may distinguish as factors— a black factor and a white one. It is convenient to use black and white draughtsmen as models with which to follow the subsequent moves of these factors. Within a pure black strain, each of the two parents of any individual con- tributes a black factor to that indivi- dual, and we may therefore represent such an individual, in respect of the character blackness, by two black draughts. We thus indicate the essen- tially double nature of all the higher animals and plants, this double nature being explained by the fact of their having arisen from two separate parents. In like manner, a member of a pure white strain may be represented by two white draughts, and the cross between a pure black and a pure white strain may be represented by one black and one white draughtsman placed together. In the yarticular instance which we are considering the cross bred individual appears black—in technical language black is said to be dominant over white, and white is said to be recessive. This fact can be represented by placing tha black draught on top of the white one; but we must be careful to remember that the white draughtis also present all the time, only it is hidden ucderneath. In the same way in the black cross- bred mouse, the character whiteness exists in a latent condition (better called recessive), although to all appearances the creature is pure black. We now arrive at the crucial point of the whole story. When the cross-bred individual forms its reproductive cells, — Miscellaneous. the behaviour of the black and white factors is the simplest conceivable. We have to picture the original black and white-determining particles—whatever their nature may be—to have multiplied to such an extent that there is now a pair—a black and a white—in every one of the cells which build up the organism. Each of these cells has been produced by the division into two equal parts of a previously existing cell, and in all ordinary cases the black factor (for example) divides into two before the cell divides, and half passes into each of the new cells formed, But in the division which leads to the forma- tion of the reproductive cells the factors do not split. On the contrary the black and the white factors separate from one another. And every repro- ductive cell which arises contains either one or the other—a black or a white— but never both together and never a blend of the two. Thus if we pay atten- tion simply to this pair of characters. black and white, we can represent the repoductive cells of the cross-bred indi- vidual by any number of single black and white draughts—an equal number of each; for it appears that in both sexes each of the two factors turns up in very nearly the same number of repro- ductive cells. Now suppose a pair of these cross-bred individuals to be mated together. The essential process of such mating con- sists, of course, in the union of a pair of reproductive cells, one derived from either parent. So far as we can tell these reproductive cells will meet entirely at random. It is like an experiment in which one draws a single draughtsman out of each of two bags, supposing each bag to contain an equal number of blacks and whites.

He takes the number of acres of tea planted and the total quantity exported yoar by year for the first 13 years of the existence of the Ceylon tea industry ; and this he contrasts with the first thirteen years of the working of his own estates. Heo makes out that during tho period Ceylon attained the maximum production of 14 lb. per acre, while on his plantation 146 lb. per acre was attained. His tigures as regards Ceylon merely represent the amount of tea ex- ported and take no stock of the quantity consumed locally ; but he does not point out that, in the early years, there was of course no tea in bearing. On the other hand he has been able to account for every ounce of tea produced on his own property. At the present moment Ceylon is producing 460 1b per acre all round on an average and not a few estates in the island are giving 1,000 lb. per acre. What is M.

CARRUTHERS EXTRAOTS INFORMATION FROM A LECTURER, A most interesting paper on ‘‘ The Resources of the Peruvian Andes and Amazon,” by Mr. C. Reginald Knock, F.r.¢s., Civil and Mining Kagineosr, was read before an ordinary meeting of the Society of Arts on April 28th. The paper dealt mostly with the mineral wealth of these countries, but rubber was frequently mentioned, and at the close some further interesting infor- mation was adduced in the course of discussion by Mr. J. B. Carruthers among others. From the lecturer's paper we extract the following : There are gold mines ; untold wealth of silver ; there is copper and coal and guicksilver in abundance; and farther on yet there is wealth of rubber and timber and chocolate and sugar. cane, great herds of sheep and cattle and alpa.- cas, and many other matters of satisfaction to the traveller, the capitalist, and the merchant... And far beyond tho great Cordilleras we shall see canoe-loads of ‘tblack gold,” the rubber from the forests, as the rubber-gatherer shoots down the rapids of the Amazon affluents towards the [quitos market. Tho wealth of an empire lies within and beyond the Andes and upon the Peruvian Amazon, waiting only the set of humanity that way to gather it in for huma- nity’s use. Leaving the high regions of the Andes wa descend to the third natural zone of Peru, the ‘*Montana,” or region of the forests of the Amazon plain. The natural resources of this vast region might be summed up by saying that it forms one of the world’s great natural store. 580 houses for the future. It is traversed by navi- gable streams and rivers in great part; all affluents of the Amazon. Of these waters 10,000 miles are navigable at all seasons of the vear for steamers of varying draught, whilst in the wet season tho total available navigable waters in rivers and streams, for steamers, launches, and canoes, exceeds 20,000 miles, all in Peruvian territory. The main product of this wild region at present is rubber, of which the output is valued at about 14 millions sterling per annum. In the Peruvian montana there are very extensive rubber- bearing forests, both in that part of the Amazon plain drained by the affluents of the Madre de Dios river, and, although less known the region to the north drained by the Maranon and Huallaga. The principal Peruvian rubber- bearing trees are the Shiringa or Hevea, and the Caucho. The Hevea is the superior kind, and is that which has made Brazil famous as a rubber producer, The tree requires a rich, deep soil and abundant moisture, and at times grows to great size. It lends itself to cultivation, although not much has been done in Peru yet in rubber-planting. Large areas of rubber- bearing land have been taken up in Peru; prin- cipally by Peruvians but partly by foreign com- panies; though much land still remains un- occupied, Discussion. Mr H Hamel Smith enquired about the nature of the labour available, and whether any would have to be imported, provided it was decided to cultivate rubber in Peru. It would also be of interest if informetion was forthcoming as to whether the cost of the land would be an important consideration in the question, and whether the transport of the rubber when it was grown would be a serious matter. Would it be possible to bring the produce down to the Pacific coast instead of, asat present, having to make the long journey down the Amazon to the Atlantic seaboard? Unless that were possible, it wouldrender the profitable cultivation of rub- ber in Peru quite hopeless compared with the Federated Malay States and Ceylon, where the costof transport was comparatively low. He understood that therubber grown in Peru was of excellent quality, asit wasin Bolivia, but the danger and expense of cultivating it was very great. Miss Webster thought the value of the paper would be increased if the author could givesome particulars of the trees found in the forests. Were there any timber trees ? Mr J B Carruthers asked the author for in- formation respecting the proportion of Para rubber trees in the natural jungle region he had described as rubber-producing, and what were the possibilities of extracting the rubber from them, apart altogether from the question of planting rubber. Mr Enock, in reply, said that labour in the forest regions was rather scarce, and he believed some of the rubber companies engaged there had found that their main difficulty. Peru was anxious to introduce Japanese labour, a good deal of which was employed on the coast. The natural outlet of the rubber region was down The Supplement to the Tropical Agricultwrist the Amazon, because the rubber forests existed on the tributaries of that river, It had, never- theless, been found cheaper by some of the companies working the rubber lands to bring the rubber over the Andes and down the rail- way to Mollendo. As soon as roads, perhaps motor roads, and short lines of railways were constructed on the natural outlet down the Amazon, he thought, there would be an enor- mous development of trade. The Amazon forests possessed the peculiarity that they were unlike the other forests of the world, which. consisted very largely of one kind of tree. They consisted of all kinds of trees, in fact, he believed it had been calculated that in one square mile there existed thonsands of different kinds of trees, and this rendered the Amazon forests perhaps of less value than some of the other forests of the world. If a particular kind of tree was re- quired, it was sometimes necessary to hunt about for it a good deal. There were, however, great groves of what was termed cedar there, although it was not a true cedar; but it was a valuable wood, Valuable hard woods also grew in the forests. The question of the proportion of rubber trees to other trees was hard to answer. The rubber-bearing land was confined to acertain zone of land upon the margin of the rivers which were tributary to the Amazon ; but it was impossible to state the exact proportion it occupied of the total area. CULTIVATION OF A SANDY SOIL. Sandy soils are of various descriptions ran- ging from those in which sand largely pre- dominates to othera which are of a sandy loam, and, in consequence, highly desir- able for the production of potatoes and many other crops. The disadvantages of a sandy soil are that it is deficient in lime, in sub- stance, and in vegetable matter, while it is often so porous that it fails to retain moie- ture during the growing season, when, how- ever liberal the farmer may be in the provision of manure, especially of artificials, he fails to obtain a paying crop. It is extremely ditlicult to cultivate with profit sandy soils of many classes, for the simple reason that they are so subject to suffer in a droughty season. It is true that much is saved by the easo with which they are cultivated with the plough and other implements, while they can be cleaned at much lower rate than land of a more substantial character. An owner or at occupier of a sandy soil, if it isnot toolight in character and will pay. for extra cultiva- tion, will be well advised to improve it by the addition of clay or marl, and especially by the cultivation of crops which are rich in nitrogen for the purpose of ploughing in. In Germany very large areas have been improved so much: by persistent cultivation that they have reached a substantial price, al- though originally purchased at some 12s an acre. Suppose that a commencement is to be made. Something should be done in the way of mar- ling, while potassic and phosphatic manures may be supplied with some liberality for a few years in succession in order to feed the plants which are to be grown for ploughing and Magazine of the Ceylon Agricultural Society. in, Tho vetch might be taken as an example, for by the aid of the mineral manures it would be in a position to obtain its own nitrogen from the air, especially if aided by the dril- ling of some fertile soil with the seed, and thus, when ploughed beneath, it would not only provide a quantity of humus and make the soil more substantial, but provide feed- ing matter for the succeeding crops. There is no likelihood of a loss of the potash or the phosphates owing to heavy raiu, although, under certain circumstan2es, a loss of nitrogen might be sustained, A crop of vetches sown in spring and ploughed beneath might be followed by a crop of rape or rape and mus- tard, either ploughed beneath, as in the case of the vetches, or fed off by sheep receiving artificial food. And so, from year to year until a sufficient time has elapsed to induce the grower to attempt a potato or a corn crop. This he would do on ascale not too exter— sive, taking overy care to provide manure, IT am speaking of a farm upon which it is impossible to use dung, owing to the fact that crops are not grown with which to produce it. In course of tims—that time depending upon the original and substantial character of the soil, for the more it approximates to loam the better it would bo, and the earlier it could be cropped with grain—a great Improve- ment would be made. tinue to plough alarge quantity of green forage beneath the soil from year to year without obtaining some tangible result. ‘The soil would gradually accumulate fertilising matter in such quantities that it would be able to grow good crops of grain, roots, and potatoes, and, indeed, ofa variety of other plants, and with these chiefly consumed upon the farm, manure would be made, and the larger the quantity the better for distribution on the land. Thus, by the aid of the dung of the farm, it would not be essential to purchase so large a quantity of artificials. Some years ago an agricultural scientist in France made a number of experiments on a somewhat extensive scale, with the object of ascertaining how a soil should be composed in order to produce the largest yield of the leading crops grown by farmers. He found tiatif the four typical varieties of soil, those chiefly com- posed of clay, chalk, sand, and peat, were mixed together in equal volumes, he obtained the best results, Such a soil was mellow, easily worked, rich in lime and humus, and capable of retain- ing moisture in hot weather, while responding well to artificials. There are, indeed, certain varieties of plants with which the gardener is better acquainted which require soils of differ- ent types, but this fact can easily be verified by any observant man who examines the weeds which grow on every class of soil, He will, for example, find the sandwort, the field madder, the mugwort, and bent grass upon sandy soil ; on chalk land he will find the spikenard, the yellow hawksbeard, and the wooly thistle; and so, in wet soils, in marshes, on gravels, and clays, different varieties of plants are found which are seldom seen in other places ; indeed, the weeds, like the timber trees, indicate very closely the variety of soil upon which they grow. The farmer, how- ever, is compelled to adapt his crops to the soil Ié is impossible to con- © 58i he farms, and itis for this reasou that he has adopted certain methods which enable corn and other crops to grow with freedom and success, ff asoilis damp, he drains it; if it is tenacious like a heavy clay, he endeavours to reduce its tenacity and make it porous by the addition of sand, lime, the ploughing in of green crops, heavy dressings of farmyard manure, and plough- ing ab particular seasons, when it falls to pieces and provides a finer tilth. So itis with soil of a sandy character, which fails to hold suftlicient nioisture for the use of plants, which is but slightly fertile, deficient in humus, lime and such matorials as clay, which are best catculated to make it more substantial and adapt it to retain moisture and prevent the loss of nitrogen, which is so easily carried through it by the rain. MERLIN, —The Field, April 17. THE TEA SEASON IN JAPAN. The now tea season is about to setin. The first shipment of new tea this year, says the “Mainichi Dempo,” was made by the ‘‘Korea,” which left Yokohama for San Francisco on April 24th. In anticipation of the rejection of the proposed tea duty in America the Yokohama and Shizuoka tea markets are now actively pre- paring for the opening of tho season. This year’s tea crop is not particularly different from that of last year, but the state of the markets at home and abroad seems to be very promising, The amount of tea exported from Japan between May, 1908, and April, 1909, was 32 million pounds, showing a decrease of about two million pounds as compared with the previous year, In consequence stocks of last season tea in America this year are not so heavy as in ordinary years, while the remnants of old tea in Yokohama and Shizuoka, which will be exported in the course of the present month, do not exceed four million pounds in quantity. Thus stocks of old tea are comparatively low both at home and abroad, Moreover, the conditions in America in respect to the demand for tea are improved, the finan- cial crisis of last year having nearly passed away, On the other hand, the money market in Japan is easy. The situation is, therefore, advanta- geous for tea transactions at present. Accord- ingly, tea merchants in Japan are more encour- aged than in ordinary years, and itis believed that the amount of exports will be largor than last year, The standard price of new tea is ex- pected to be somewhat lower thau the average price last year (Y.24 or Y.25), Tho direct ex- portation of tea from Shizuoka is yearly on the up grade in volume. The Fuji and Kyodo Companies at Shizuoka, as well as the local branch of Messrs Jardine, Matheson & Co., have already commenced the necessary pre- parations. The favourable market conditions there will be maintained as hitherto in compe- tition with the Yokohama market. It is ex- pected that nearly all the representatives, in charge of tea, of various foreign firms in Yoko- hama will return to Yokohama by the ‘‘Siberia,” —Times of India, May 15, 582 The Supplement to the THE MYGOLOGIST GIVES WARNINGS ON RUBBER TAPPING, Anp tHe NorTHWAY SYSTEM. We direct the attention of our rubber-plan- ting readers to the warnings given by Mr. . Petch, the Government Mycologist, on the question of rubber tapping; and specially should they note the injunction that on no system whatever is it permissible to tap over more than half the circumference of the tree at the same time, The Northway system directly contravenes this rule; the tapping, we be- lieve, 18 carried on right round the stem. We do not know that this is fatal tu the system, how- ever, for it is possible that the system could be modified in this respect if the present method is found to be injurious to the tree. In this con- nection a Colombo Estate Agent, answering an enquiry today, says :—‘* The Northway system is on its trial. Deviturai trees were doubtless heavily manured; and poor and unmanured trees will not give the rush of iatex which can be shown to visitors by Mc. Northway ; but I have no doubt damage by his system is being done (as at first by the old V method) owing to care- less work, and tapping trees which are too young with thin bark through which the pricker goes into wood—also, by the cutting through of thin bark by hoop-iron channels which in some cases have been stuck in without regard to their effect on the bark.” May 12th. Sim,—Your readers should be warned that on no system whatever is it permissible to tap over more than half the circumference of the tree at the same time. This is the maximum, where trees of small girth must be tapped for finan- cial reasons; the optimum is about one-quarter circumference. ao The statement that the latex from the upper incisions of the Northway system flows into the lower incisions, etc., must be accepted with more than the usual quantity of salt: 16 1s i sible. . 9 es ; cael the wounded bark is thin, it might be (3) IANA > ted to split away from the wood and die in patches. in ne drier rubber distritcs. This happened under the old system in the Kandy district, especially when the tree was tapped with consecutive V’s about a quarter of-an-inch apart. T. PETCH, PACKING PARA RUBBER SEEBS FOR EXPORT. {n the Agricultural Bulletin for November, i908. (Vol. VIL. No. 11), in which the method of packing Para Rubber seeds for export is fully described, mention will be found of a consign- ment of 52,000 seeds which was sent to the Botanic Gardens, British Guiana from the Botanic Gardens, Singapore and the seeds being sown they gave a germination of approximately 30 p.c., this after a journey of over 53 days.

CHARLES T, Cox. | The Quarterly Journal of lhe Board of Agri- culture of British Guiana Vol. 11 No. 3. Jan., 1909, publishes the following extracts from the West Indian Bulletin Vol. LX No. 3, 1908. ‘* Professor Harrison (British Guiana) said that they had given up the importation of rubber seeds from Ceylon and they now got them direct from Singapore. Within the last few months ho had imported 62,00) seeds and had got nearly 82 per cent germinating. These seeds cost on arrival about 1,2c each. They were packed in dry charcoal in seed b_xes and were sent by parcel post to ensure quickest delivery. The plants when ready for delivery had cost al- together 2°58c each. The last consigument of Hevea bra- siliensis seeds from Singapore had alrei:dy given a propor: tion of very nearly 86 per cent germinating in a total of about 59,000 se ds.” These figures speak for themselves and go to show that proper packing and careful planting at the end of the journey is all that is necessary to ensure the entirely satis- factory export of para rubber seeds to other ‘Tropical Colonies, : ; _ I.

Ata meeting of the Committee charged with the management of the State of San Paulo Govern- ment coffeo, held today under the chairman- ship of Baron Bruno Schréder, the following statement was approved :— 1. With reference to clause 2 of the circular dated January 5, 1909, the Committee states that no sales of coffee have been made, that the contemplated sale of 500,000 bags will not be undertaken until the trade is ready to pay the price stipulated therein, or its equivalent in any of the markets, and that in no case shall the sales during the current year exceed 500,000 bags. 2. Vhe Government has lately had under its considera- tion the advisability of replacing the existing law, limi- ting the export of coffee, by A NEW LAW CREATING AN EXTRA DUTY of 10 per cent on all exports of coffee payable in kind, such coffee to be destroyed under the control of the Committee. This law would, in the opinion of the Government, bring aboutthe same result as the existing law, but in a more satisfactory manner. The change would appear to the Government to be most desirable, as it would obviate the rush to market the crop, which would undoubtedly take place under the existing law; the planter would thereby be given time properly to prepare bis coffes, the exports would then, as in former years, be spread over the whole 12 months, and the qualtty, of the coffee reported would bo improved by the destruction of the lowest grades. Such alteratiou of the law would also bo desirable in the interests of the coffee trade, of labour, and of the railway and shipping companies, and would at the same time assure the stability of the exchange. The Guvernment has now approached the Committee officially on the subject, having set forth its reasons. as above, for desiring an alteration of the law, and the Com: wittes, after careful conslderation of all interests, is of opinion that the proposed change of the law 4s destrable, and will ocnsider the feasibility of such an alteration. The Federal Government of Brazil is ready to sanction the proposed change in the law.—London Times, April 28 and Magazine of the Ceylon A yriculliural Society. RUBBER IN SUMATRA. PROGRESS ON THE EAST COAST. The opening of the east coast of Sumatra (Sumatra Oostkust) goes back to tho ‘sixties when tobacco was first grown by Kurcpeans. Why was this parf of Sumatra opened in pre- ference to any other on that side of the Straits of Malacca ? Was the soil unique in its com- position as tobacco requires it to be? Was it ecause Deli and the neighbouring districts lay nearer to the busy island of Penang, an old landmark on the trade route between Europe and the Malay Archipelago ? As with ali sub- sequent wonderful developments, the origin of tobacco cultivation on the east coast is sur- rounded by legends. Tho tact, however, re- mains that the attention of Kuropeans was one day attracted to Sumatra tobacco grown by natives on the vast coast, and from that date to- bacco has been and remained the agent of the whole progress of the east coast, progress un- paralleled elsewhere in the Kast except in the F.M.S. Tho measuro and peculiar significance of that progress is to be judged from the official statis- ties (1906)—the only reliable source of informa- tion. Whereas, for the same extent of territory, the west coast has an excess of officials over non- officials (409 officials, 88 traders, 34 contractors, and 42 planters), the east coast stands in the opposite relation (134 officials, 146 traders, 307 contractors and 507 planters). The prepon- derance of officials in the west is to be explained by the greater density of tho native population, its better climate, and in Padang, up to quite recently, the coffee cultivation under Govern- ment control. The preponderance of civilians in the east is due to the development of tobacco cultivation asa private enterprise. Striking features ap- pear in the statistics for the east coast, the low density of the native population, the high per- centage of imported races, Chinese and Javanese especially, Klings, -Bengalis, etc. Let us ox- amine those features before we pass on to what concerns us here—the work of Europeans, with epecial reference to rubber and their life gene- rally. THe Native PopuLation, Tobacco is not responsible for the low density of the native population, as, for instance, rubber has been in vast districts of the Congo, although it has accommodated itself rather well to the situation. For greediness of laud tobacco is un- equalled. 1t devours larger and larger spaces until after eight years it can come back—with- out prejudice—to its growth in the soil it first occupied, Reservations for natives would neces- sarily stand in its way, and it was not a misfor- tune that the country was more or less empty. Java would have been an awkward place for it to move about in. Going from Tandjong Balei to Tandjong Poera, that is, from south to north- for milesand miles one sees endless strips of land covered with lalang and blukar where tobacco has passed and left devastation behind. One longs to arrive at kampongs, which are like so 583 many oases in that desert. ft must be con- fessed, en passant, that the sight is less unseemly than that of the scars and holes that disfiguro beautiful spots in mining districtsin the F M.S, THE CHinese IMMIGRANT. Just as in the F.M.S.—always one’s standard of comparison when one wants to measure the progress of other colunies—the country has been opened and developed by the Chinese before the advent of the god Rubber;in the same way Sumatra’s east coast has looked for its labour to China, I say “has looked for its labour,” for there has been no initial Chinese enterprise except in the petty trade of the towns. ‘The Chinese cannot obtain conce ssions. The Dutch tobacco companies have protected themselves against their possible competition. Kich towkays would have commanded Chinese Jabour to the exclusion of any other and might have proved a state within the State. As it is, the Chinese represent 20 per cent. of the popu- lation, But their community has no perma- nency, owing to its special character, being composed almost entirely of men (88,856 unmar- ried as against 9,877 married.) The few rich Chinamen are the captains of an army (the ex- pression “Capitan China” is not inappropriate) rathor than the heads of a community. Their influence over the coolies is great, but the coolies will remain a huge army which can be disbanded when its services are no more wanted. That event we shall not wibtnoss. Tobacco would have to cease to exist, and, as we shall see, Dutch people do not believe in its disappearance. The high percentage of the Chi- nese population can only be counterbalanced by an influx of another imported race, and that the rubber industry can be expected to bring about—as it is doing in the F.M.S. with Tamils, LaBour. Javanese are the imported race on rubber plantations in Sumatra. The cost per coolie is 80 guilders (1 guilder=70 dollar cents), 30 of which are recoverable, Though the contract lasts three years only, the coolies, on an ave- rage, remain seven or eight years, which brings the cost of recruiting to about the same as in the F.M.S. The source of supply is inexhaustible which ismore than can be ‘said of the Tamil districts in Southern India. If we add that climate and soil are as good as inthe F.M.S8 one can look forward to an increase in the acreage under rubber. That increase will receive a great impetus once Dutchmen en- gageinit. Up to the present no Dutch com- pany has been formed for the purpose of planting rubber. The Dutch tobacco com. panies have. more’ than 350,000 acres wholly unsuitable for tobacco, though in most parts very good for rubber. They pay a quit rent of 1 guilder a bouw (1? acre) for land that cannot be used, and yet they will not part with a plot of it, even when it would oblige a rubber company, their neighbour. It would take away something from their standing and dignity. The only tobacco companies that have taken up rubber are English, the Shanghai Su- matra Tobacco Co., the United Langkat and Paya Jambu. A fow small tobacco properties belonging to private individuals or defunct com- panies have also been turned into rubber estates, 584 Op Correrk Lanp, The greater part of the coffee land has been put under rubber, most of the estates under- going the same transformation asin Malaya; and all of them were started with Swiss or German capital. Their rubber is not very old and not kept up tothe mark, owing to lack of funds. The soil is not alluvial, as was most of the soil under coffee in the F. M. 8., but had it received proper care and attention, it would show ultimately a better growth and a heavier yield in rubber, judging from similar soil under more fortunate circum- stances. This leads me to consider the position of estates belonging to companies with more capital. The work dons is impressive, both on account of the short time allowed to managers to put it through, and the large scale on which it has been done. Very little of the land was virgin forest ; a great deal of it was lalang, and much of the remainder was and is under coffce. The growth is good on lalang or old tobacco land, and this is what surprises one most, Though looking for the difference between the product of either class of soil and virgin forest, one is almost disappointed not to find it. The only rational explanation would be perhaps that lalang or old tobacco land has been dug over a sufficient number of times to make it as good as virgin land which has not been turned over at all. LALANG V, JUNGLE, The moncy disbursed for getting the soil ready for planting amounts to very much the same for lalang and virgin forest, for the following rea- sons : felling is dear, whereas digging lalang or blukar is cheap, the latter process being often resorted to. ‘Thus, taking all these circum- stances into consideration, we are gradually led to understand the following assertion of a Sumatra planter: ‘‘[f I were to open again, | would rather open on lalang er tobacco land.” Planters, who are now struggling with fungus and white ants, will fully appreciate this view, The hosts of virgin forest are not to be go easily driven out of their abode unless every stump and root is taken out and burnt. Then it is no more clearing the jungle as in the old days; it is modern cleansing with all its cortege of machines. The expense of opening jungle land is therefore increased, but in that case the earth has necessarily been turned over, and the returns must prove greater than in the case of previously cultivated Jand. There is much of this latter class in Sumatra, and it will be interesting to see what yields 1t gives. The experiment was needed. A Goop ScHooL, The impression one carries away is that tobacco is a very good schcol for planting life. Comparatively young men acquire great exper- jence in handling large and mixed labour forces, and older men, in managing the huge resources placed at their disposal by their powerful com- panies. English planters, from want of previous experience, might encounter more difficulties in dealing with such bulky concerns. The training has been longer and not so chequered and in- terrupted as in Ceylon and the ¥.M.S. It is quite normal to hear of Europeans having only been home twice in 20 years. The only holidays The Supplement to the Tropical Agriculturist are the Ist and 16th of the month—no Sunday rest. The work is hard and especially exacting in May, June and July—everybody in the field at 5-30 a.m., back at ll a.m., and out again at 1 p.m. till 6 p.m. SPANDARD OF LivING. Against this, living is on a higher standard than in Ceylon or the F M §&., judged from the point of view of food and houses. It is a real pleasure to go to a far-away estate and find fresh milk, fresh butter and new-made bread, instead of tinved or stale articles. The meat is excellent, owing to the presence in the country of Kuropean butchers, who cater for the other Europeans. It isa pro- fitable business and not below their dignity. By the way, why should it be infra diy, to trade in fresh products, and not so to deal wholesale in tinned ones? There is no objection amongst Dutch people to keeping a shop or managing a hotel, and consequently there are good shops and good hotels. In Sumatra, as in Java, the houses are very comfortable, being well furnished and provided with all the conveniences that may be found in Europe. The tobacco companies have not be- grudged the money for the grounds surrounding managers’ houses, with the result that the latter are laid out with a certain grandeur. Sumatra planters are fond of saying that assistants in the FMS are sometimes put in bungalows where they would not put their coolies. The Impression throughout is that Europeans are there for a longer time than in the FM§, and it is confirmed by their relations with the natives and their treatment of the Eurasian question. One realises that every detail of their hfe isin accordance with the rest.

( Special.) The common almond tree (Amygdalus com- munis) is a native of Asia Minor andthe North of Africa where it has been cultivated from ancient times. One of the earliest references to it is found in the Old Testament. The fruit is either sweet or bitter—a fact which many botanists have endeavoured to explain by a differenco in species. The probability is that the original almond was bitter and from it the sweet almond was produced by selection, the latter being after- wards brought to perfection by careful culti- vation and broken up into a number of varieties. In the cultivation of the almond in modern times the FIRST RANK HAS BEEN CLAIMED BY FRANCE, from which country the best and the best- known varieties are, for the most part, obtained. Some of these varieties, which belong to the class of the sweet almonds, are known as Amande des dames, Languedoc, Sultana, Pistache and Douce a coque dure, and each is characterised by the size, form, flavour, etc., of its fruit. This position, however, occupied by France, has recently been imperilled by the formidable rivalry of California, which has succeeded in producing several new valuable varieties such as Excelsior, Non plusultra, Nonpareil, Il Suprama and Commercial. The latter deserves special mention. The tree exhibits a peculiar com- pressed growth and retains some leaves until the end of winter. It is very prolific and the almonds, provided with a thin husk, are sweet, delicate and very large. In the trade, however, the JORDAN ALMONDS ARE PKIZED the most. These are not, as is commonly sup- posed, produced on the Jordan, but in the neighbourhood of Malaga (Spain). No doubt their good qualities are due to the influences of soil and climate, for this variety does not meet with the same favour in other countries. Next in order of merit come the broad almonds of Valencia, to which the previous remark is also applicable. The almonds of Provence are also renowned, which is indicated by the fact that in the commercial city of Aix the annual turn-over in this commodity reaches the value of £125,000. France’s total exports of almonds to foreign countries are valued yearly at £800,000, THE SWEET ALMONDS contain considerable quantities of a very delicate fatty oil, also sugar, gum and mucilage. Beside being very nutritious they possess a pleasant taste. They are used for the most part in fancy bakery, in the kitchen, as dessert and in medi- cine for the purpose of making cooling drinks. The bitter almonds contain the same substances, but in addition Amygdalin, from which a pecu- liar volatile oil is prepared. This oil, when puritied, is likewise used in the kitchen and fancy bakery but also in the toilet soap factories for perfuming purposes. In the impure state it is sometimes employed in medicine in place of pure prussic acid, 74 585 The almond tree THRIVES BEST IN THE SUB-TROPICAL ZONE, where it is indeed a native, for neither a moist nora cold climate is favourable to its growth. In the warm revions of the temperate zone, however, its cultivation is also successful; only the harvests are always very uncertain on account of the injury that is often inflicted by the frost on the early shooting buds. The sweet almond is even more sensitive to cold than the bitter one,and consequently its sphere of cultivation is much more limited. This fact, combined with the keener demand there is for it renders the sweet almond dearer in price and therefore, its cultivation more remunerative. For this reason the preference should always be given to the cultivation of the sweet al- mond; that is, in those places where the cli- mate and soil are quite suitable. Like the fig tree, the almond cannot stand the exces- sive moisture of the tropics and it is only grown there at the expense ofits fertility. The CLIMATE AS WELL AS THE SOIL SHOULD BE WARM AND DRY; addition, must be free and possible, rich in lime —such a soil, in fact, as is required for the cherry tree in the temperate zone. The most favourable situation for its cultivation is on the ridge or slope of a hill, Level land should only be chosen when there is no danger of it being flooded. While a large amount of moisture is injurious, it is also im- portant that the needs of the almond tree are completely satisfied in this respect. It has been found by experience that artificial irri- gation has a detrimental effect. Although the tree is not specially sensitive to wind, it should not be left exposed on all sides. If there is no protection afforded by elevated ground, a natural barrier in the form of trees may be set up to break the force ef the wind. For the CULTIVATION AND PROPAGATION OF THE FINEST varieties of the almond tree, grafting is also essential, and this gives rise to the ques- tion: What are the most suitable trees to use for this purpose? The selection of these will depend, to a great extent, on the soil and cli- matic conditions. In districts, for example, where it is desirable that some power of with- standing the influences of the weather should be imparted by the process, the plum tree will be found the most advantageous (Myrobolama excepted}, and especially’ the fast-growing and early ripening varieties. The grafting should be done on a twig not thicker than } inch ; otherwise the growing over, of the part where the grafting has taken place, will last too long. If, on the other hand, the soilin question con- tains more moisture than is good for the almond tree, the peach tree, as being partial to a moist situation, should be chosen asa base. In the case of avery dry soil, however, it is recommended to employ the almond tree itself and preferably the bitter variety, if the soil and climatic conditions are favourable to its growth. Where the latter is not available, the hard-husked sweet variety or even one of the soft- husked varieties may be taken for the purpose, In the growing of almond trees for the purpose of grafting, the seeds should be first the latter, in deep and, wherever 586 pressed gently on the sides until the out- side green husk is no more than evident. Care must, of course, be taken in the process that no harm is done to the kernel, The seeds are then put into a carefully prepared bed at a distance of 6 inches from one another and covered with light fine earth toa height of 2 inches. If protection is necessary against vermin some lime and ashes may be spread over the seeds. In districts where the wiuter is so severe that the sowing of the seeds harvested in the summer or autumn must be postponed until spring, or where the postponement is deemed advisable, the seed should be placed in slightly moist sand and stored in the cellar during the interval. When the trees areas thick as a pen-holder they are grafted 1—2 inches above the ground. Inthe sub-tropics when the treesare well-treated THE GRAFTING CAN TAKE PLACE IN AUGUST, provided that the seed was sown in the spring or in the previous autumn. The transplanting will then be carried out in the following spring. The most suitable distance to be left between the trees is 5 yards in each direction; it is only in dwarf culture that the distance can be reduced to 4 yards. The harvesting of the almonds is simple and convenient. It is only necessary to wait until the green outside fruit husks have sprung open when the almonds, which have fallen out, may be picked up from under the trees. This, how- ever, requires a good deal of time, for the springing open of the husks does not take place within a narrow limited period and is besides only incomplete in the case of many varieties. It is preferred, therefore, in the larger plant- ations to pluck the almonds like other fruit and break open the husks after they are brought into the granary. Thisis alsoa slow process if carried out by means of a wooden hammer, so that the invention of a machine for doing the work is a ‘‘consummation de- voutly to be wished” by the almond cultivator. FERTILISATION, With regard to this subject there is unfortu- nately not much available data on which to base conclusions, but the facts that are known are presented here for the consideration of the reader. The amount of plant food contained in the leaves and branches of the almond tree is practically immaterial for our purpose, as_it is for the most partreturned to the soil, What we must consider is the quantities of the im- portant constituents that are withdrawn per- manently from the soil through the medium of the fruil. According to the analysis of Zedeler, the almond contains :— 38°20 parts per 1,000 of Nitrogen 13°70, aa 3 99 Potash », Phosphoric acid », Lime £30 aisie he stah se A tree, therefore, in full bearing, which yields annually 45 1b of almonds (without husks), will remove annually from the soil :— 1°68 lbs Nitrogen 0°60 ,, Potash 0:94 ~,, Phosphoric acid o'19 ,, Lime The Supplement to the Tropical Agriculturist Assuming now there aro 40 trees to the acre, we find that the quantities of the important fertilising ingredients removed per acre from the soil by the corresponding crop of almonds— 1,800 tb,—are :— 67°2 Ib. Nitrogen 37°6 lb. Phosphoric acid 24:0in. Potash (Pas Lime From these figures it is plainly evident that, if the almond tree is to maintain its prolifity, the soil must be replenished with the proper amounts of plant food. How is this to be ac complished? In the first place, it will be neces- sary to find an economic method of supplying Nitrogen, for it would prove too costly to apply this constituent all in the form of chemical manures. From the figure given above there would bo necessary for this purpose no less a quantity of Nitrate of Soda than 3} cewts. per acre. It is preferable, therefore, to have recourse to green manuring and to supple- ment this with small quantities of Nitrate of Soda or Sulphate of Ammonia. On calcareous soils, or soils which are not poor in lime, Sainfoin should be cultivated every third, fourth or fifth year and ploughed in at the time of flowering. This will supply with roots, stems, etc., at least 180-220 lb. of Nitrogen per acre, corresponding to 10,000-13,000 Ib. gresn material. This manuring along with an appli- cation of 2-24 lb. Nitrate of Soda or Sulphate of Ammonia per tree will provide sufticient Nitrogen. On sandy soils it isadvisable to grow lupines every second or third year. This crop, buried in the green condition, will supply 130 Ib.- Nitrogen per acre or 13,000 lb. of green material. Inthe case of many sandy soils or sandy- loams the better plant is Bird’s-foot (Orni- thopus), which will supply 10,000 lb. of green material, equivalent to 120 lb. of Nitrogen per acre, It is recommended to cultivate this crop every alternate year, In the same way, many other leguminous crops may be grown for the purpose of enriching the soil with Nitrogen, but at the same time it will be found advantageous to supplement this method by the application of artificial nitrogenous manures at the rate indicated above. Referring again to the figures at the begin- ning we find that each almond tree requires yearly 060 1b, Potash or 40 trees (occupying one acre) 240 lb. To restore this constituent to the soil, ong of the three following salts should be applied and at the rate suggested :— Per Tree Per acre (40 trees) Sulphate of Potash 14 lb. 60 Ib. Muriate of Potash nn “4 Kainit 6 lb. 240 lb, The Sulphate ot Potash should be employed preferably on the heavy soils deficient in lime, while the Muriate is to be reserved for those containing sufficient lime and Kainit for the sandy soils. With regard to phosphoric acid we observe that each tree is responsible foran annual loss of 0°94 lb. or 40 trees (occupying 1 acre) 37°6 lb. It will, therefore, be necessary to use the fol- lowing quantity of one or other of the phos- phatic manures :— Per tree. Superphosphate 5 Ib. Basic Slag 6 1b. Per acre (40 trees.) 200 Ib, 240 Ib, and Magazine of the Ceylon A gricultural Society. In cases where tho soil is well supplied with lime it is recommended to use Superphosphate, and Basic Slag wherever there isa deficiency of this constituent, Asa summary of the foregoing remarks, the following manurial prescriptions, in addition to greeu-manuring, may be laid down for the different classes of soils :— I. Heavy soils deficient in lime. Per tree. Basic Slag 6 lb. Sulphate of Potash _ 13 5, Sulphate of Ammonia.. Dees, Ii. Soils containing sufficient lime. Per tree. Superphosphate 5 Ib. Muriate of Potash Ws Nitrate of Soda 2h yy III. Sandy Soils. Per tree, Basic Slag . 6 lb. Kainit ie (a Sulphate of Ammonia... CAPR These manurial recipes, of course, apply only to trees which are in full bearing. In the case of younger trees and trees planted more closely togethor, the quantities of the different manures fer application per tree will have to be lessened and calculated in the same way according to the yiold per acre, The above calculations were also made on the assumption that the soil on which the almond trees are cultivated is naturally poor. If the soil be fertile, however, it is clear that tho quantities of tho manures may be correspon- dingly reduced. It is impossible here to enter into details, but it may be stated generally that the best and surest method of determining the requirements of the soil is to carry out suitabio experiments. While the phosphatic and potash manures should be applied and ploughed in ix the autumn, or at the beginning of the winter, the Nitrate of Soda or Sulphate of Ammonia will be more advantageously appiied in the spring and in- corporated with the surface soil. In soils which contain an abundance of lime, good effects will be produced by tho use of [ron Sulphate applied at the rate of 40-70 lb. per acre. In order to show finally the actual advan- tages that may be obtained in practice by the judicious manuring of the almond trees, we may quote the results of an experiment carried out in 1907-08 by Mr Emilio Albiach in Ali- cante, Spain. The trees, which were 20-25 years old at the time of the experiment, had been previously manured merely with the ashes of the husks. Three plots in all were taken and while one was feft uamanured and another received Superphosphatoe, 330 lb. per acre, and Nitrate of Soda and Sulphate of Ammonia each 80 lb, per acre, the other plot got the same quantities of the iast-mentioned materials and, in addition, a dressing of Kainit at the rato of 450 Ib, per acre, that is a ‘‘ complete manu- ring.” The Superphosphate, Sulphate of Arm- monia and Kainit were applied round the base of the trees on the 5th December, 1907, and the Nitrate of Soda in the following spring, one half in March and the other half in May, The 587 harvest took place on the 28th August, 1908, and the results may be represented as follows :— per Ib Increase in yield per acre over un- manured Ib. anuring acre crease in yleld per acre over unmanured— | Cost of manu- res or actual profit per acre from manuring. Value of in- a I. Unmanured II. Incomplete manuring (without potash) 330 Ib. Superphosphate 80 1b. Nitrate of Soda 801b. Sulphate of Ammonia 975 642 £2 13s III. Complete manuring 330 lb, Superphosphate 80 lb, Nitrate of Soda 80 1b. Sulphate of Ammonia 450 Ib, Kainit ® Yield per acre | 1,532 1,099 £6 8s Comment on these results is needless. They testify clearly enough to the practical im- portance of restoring to the soil in the culti- vation of the aimond the three chief ele- ments of plant food—Nitrogen, Phosphoric Acid and Potash. GEORGH A. COWIE, M.A., B, se, CLEAN-WEEDING RUBBER ESTATES. May 14th. Dear Six,—A good deal has been written on the subject of clean-weeding rubber estates, Both those iu favour of, and against the system have much to say in support of their convictions which deserves serious consideration. But what the rubber planter wants is the ultimate analysis of the whole question, Personally, I find that clean weeding tends to promote greater growth of the tree, and this is generally acknowledged. Jf exposure of the soil results in surface deterioration, it obviously does not affect the plant injuriously, while the decidu- ous character of the Para rubber tree would seem to prevent impoverishment of the soil. Then again, clean weeding is only necessary during the first few years of the life of an estate, 7,.¢. until the branches of the tree afford over-head shade, If, therefore, the planter . finds that clean weeding helps the tree to grow more quickly, returns on his outlay are sooner realisable, This is a consideration not to be neglected unless if can be conclusively proved that clean weeding during the earlier years of the existence of a plantation affects it injuri- ously later on, I have adopted a system of clean weeding along the lines of the trees, and at right angles to the slope of the ground, which seems to me to serve several useful purposes. The root areas of the trees are kept free from noxious weeds, and light and air are freely admitted. The cleared strips form paths which facilitate inspection of the estate, and the uncleared strips of scrub between the lines of trees pre- vent wash and thus eavethe expense of drains, whilo affording protection to the young rubber against wind. ‘“ HEVEA BRASILIENSIS,” 088 RUBBER PLANTING IN THE STRAITS. AN INTERVIEW WITH MR. E, V. CAREY. Mr, E. V. Carey, the well-known rubber planter of the Straits, was spent a fortnight in Ceylon on his way home, was good enough to give a Ceylon Observer representative a full ac- count of the present conditions and future pros- pects of rubber planting in the parts which he has just visited. Everything, it seems, was flourishing extraordinarily in the Straits and things were going on satisfactorily in every way. CROTALARIA AND Passion FLOWER. One question was greatly interesting planters there, that of growing crotalaria and passion flower. ‘‘ Personally,” he said, ‘‘I don’t think there is any one of them to be compared to clean weeding, simply on the score that on a clean estate a manager can supervise a very much larger area of land. Management is none too easy a question and to have the burden of attending to these different products, that are planted to keep weeds down, means an enormous amount of extra supervision. In some cases out there you see crotalaria over a@ man’s head and it is impossible to supervise a gang of coolies working in stuff standing over their heads. How about Mimosa ? I don’t think there’s a single advocate of mimosa in the country. It is full of thorns, which cause coolies’ feet to ulcer badly, and alto- gether, as far as I can judge, it is quite an undesirable thing as compared with passion creeper. There 1s a good deal to be said for the passion creeper as long as itis the fashion at whatever cost to try and thoroughly clean land of weeds, which are probably in themselves almost harmless, such as small -needle grass, and the plant known as valacha which Ceylon planters know very well. From what [ saw, passion creeper on land which is extraordi- narily expensive to weed, and I am not inclu- ding lalang in that, ought to be a very useful thing indeed. It is very easily cultivated on most lands and very easily exterminated; and there is no doubt that it kills all the weeds under it. It forms a tremendous thick blanket on the ground and the weeds don’t have a chance with it. They aresimply choked. I have not sufficient experience to say that it is going to do an extraordinary amount To Krrp Latane Down. 1 was told in one place in which the lalang had been cut out, and probably not properly eradicated, that the passion creeper had taken a tremendous hold to start with ; but that after some timethe lalang began to shoot up through it. I think that most old planters feel that clean weeding is the best thing, and next to that this passion creeper. Crotalaria does not seem to kill weeds, although it chokes them. TAPPING. And how about the tapping yield ? The tapping yield is all thatcould possibly be expected, and better. Tapping on most estates that I saw was very carefully done and all the The Supplement to the Tropical Agriculturist men that I spoke to seemed to take a very keen and intelligent interest in the whole thing, especially in the way in which the trees were treated, and they have the uld Ceylon spirit of thoroughly discussing and thrashing things out. Tue Nortuway SystEM, There is a lot of talk about the new Northway system of tapping, although nobody has any data to go upon. The general feeling seems to be that it is impossible to handle the pricker so carefully that it won’t penetrate the cambium and wound the wood. Our experience has been that wherever the wood is wounded, you get a knotty uneven development of the bark and stem, instead of a smooth healed surface; and a good many men appear to fear that people who com- mit themselves to the new pricking system may possibly create a condition of things in the shape ofthe trees which will render any ordinary methods of tapping by knives practically an impossibility in the future. I have no per- sonal experience of any of this suggested damger in connection with the Northway system of pricking and I only repeat what people say and seem to fear, my own expe- rience being confined to the definite knowledge of what results from wounds generally but not particularly in connection with pricking. It seems to me that we get very satistactory yields indeed; with a minimum of damage to the trees, by the ordinary shaving provess, and I think that the adoption of this new idea is rather a case of forsaking the substance for the shadow. I will not allowit on any estate with which I have anything to do although I shall, of course, be very glad to benefit by the experience of others. Tur YirLD UNDER THE EXISTING SYSTEM. Can you give me any figures as to yield under the existing tapping system ? Well, I can tell you that, on one estate, trees which are from seven to nine years old are now considered to be in full tapping order, and are yielding an AVERAGE OF SEVEN POUNDS A TREE, I can also tell you that at my own place I am getting this year 400 lb an acre from trees plan- ted 10 by 10 which are 53 to 63 years old. The feeling out there seems to be that in close planted rubber the renewal later becomes thin because it appears to be in direct proportion to the leaf head that the tree carries, and therefore it seems likely that in my own particular case, 10 by 10 planting, there will have to be thinning out in the future. THE NuMBER OF CooLiES REQUIRED. How many coolies do you want for an acre? At the present moment I have a force amoun- ting to onecooly anacre. I have 187 acres being tapped and I have a force of under 200 coolies all told. These coolies, in addition to working all that, also weed another 275 acres, roughly, and keep them in order. The whole opened area is 450 acres and I have at present a force of something like 200 coolies. That, however, is insufficient and I am going to double my force, because I believe that one should always have a considerable margin of labour, for the reason and Magazine uf the Ceylon Agricultural Society. that trees are constantly coming into bearing and that their produce should be extracted instead of being left in the tree. The ideal of tapping seems to be that every quarter all the trees that have then attained the minimum tap- ping circumference, whatever it may be, 16 or 18 inches, should be at once handled instead of being left idle, and that all the trees that have matured up tothat point should be taken regu- larly as they come on. I should think that when all the trees are in bearing, one cooly per acre would be a perfectly safe maximum for tapping purposes. I am, with the force men- tioned above, getting 400lb.an acre, but itis only in its second year of bearing. THE Cost of PRODUCTION. Is the cost of production of rubber being reduced ? Well, 1 can’t teli you that exactly. They are always improving. Do you think it will ever be put on the market at 6d or 8d per pound?—I don’t see later on why it should not be put on at 9d. per pound. A Surricrent Laspour Force. Do you think the labour force suflicient in the Straits P—I do, but the system has, of course, its apparent drawbacks. FREEDOM FROM DEBT. Do you agree with Mr R W Harrison that it is a bad mistake to Jand the coolies on the F.M.S. estates free of all debt ? No. I don’t. [think it is a very good thing as a general advertisement for the country. The individual may feol it, perhaps; but as a general advertisement for the country, 1 don’t think there could be a better scheme. I| think myself that speaking generaliy it is a splendid war cry for all recruiting that the coolies are landed without any debt. Obviously it must be. I don’t see how it can be refuted, If there is animpression broadcast in the villages that a cooly when he comes over, whatever has been spent on him. has nothing to repay, it must have a good effect. The advertisement of being able to come over free of debt seems to me of enormous value to the country. Does not the fact of their being free from debt give you less hold on them ? No. I don’t think so. As far as I under stand it, the attitude of the Gevernment is that if a cooly has a debt,the only process of recovery is a civil one. You can’t make a cooly stop longer than he wishes; and if by bolting he can evade a debt which is a burden to him, it seems to me that he is likely to do so. He is less likely to bolt if he has not got that burden. On Juara ISLAND, The Jugra Island property is of course surroun- ded by water. No spirit of any kind is allowed on the place and therefore there are no attrac- tions to coolies to enable them to squander their money. During this year, up to date, over R10,000 have been remitted to India from that place alone, through our manager, who remits all their savings, at the rate of exchange of the day, without any cost to the cooly. Planters are trying to get coolies as hard asever they can and 589 they aresaid to be coming in lots cf 10, 15 and 20 men. On Jugra Island, however, there have been four shipments of 40, 75, 90, and 125. From what I could find out there was no parallel in any other property to anything of the kind. I attribute that directly to the fact that owing to our insular position and the fact that our labour is all raw material from the Coast, the coolies have not got into touch with the gin shops and other inducements to spend money and they remain at home. Their relations and friends see the money coming over, they think itis a good country to go to, and they go. THe Estate Kappt System. We supply all our stuff from the estate kaddi, practically everything that the coolies require, On pay days if they want things they cannot get from the estate kaddi they are, up to a certain number, allowed togo to Port Swettenham in order to get what they want. Do you think the kaddi system a good one? Yes, a thoroughly good one. I am the firmest possible believer in direct financial arrange- ments between the superintendent and each in- dividual cooly. I don’t believe in letting the kangani have any financial power whatever over the cooly and I believe iv helping the cooly to avoid chetties, shopkeepors, and all people who live on his stupidity. That is the secret of pro- per organisation and control. I don’t say itis possible in Ueylon, but I believe it is. THE HEALTH OF THE COOLIES, How about the health of the coolies ? The health varies very much in different places, but speaking generally one does not hear so much about ill health as before. On ourown piace, Jugra Island, for instance, the day that I went into the hospital [ found three in the hos- pital out of a labour force of something like 1,700. I think that on the whole the conditions are in favour of labour going over, SANITATION, Have you done much in the way of sanitation? There isa movement on the part of Govern- ment now to regulate sanitation pretty closely in connection with this ANCHYLOSTOMIASIS, There is no doubt whatever that it isa move- ment in the right direction because the anaemic condition of the coolies, which is directly due to anchylostomiasis, is very pronounced and very common, especially when they come over from the coast, but the Government must be very careful how they get towork. They are trying to introduce the latrine system but there are difficulties in the way and they must proceed cautiously. They must be careful, for instance, not to run up against caste prejudices. WHITE ANTs. Mr. Carey then referred to the trouble caused by white ants and fungus and said :— I don’t think the white ants area very serious thing at all. I believe planters have the con- trol of them on quite simple lines, entirely in their own hands, but I don’t think the subject has been as carefully gone into as it should have been during the last few years and con- 590 sequently ants have got established on patches of estates and they take some time to eradicate. The new pump, by means of which a hole is bored in the tree and gas forced in, is likely to doa great deal of good. In one case I heard of, fumes were forced into a trea and came out of another 30 or 40 feet away. All the ants in that area were destroyed. Lhe nests must be got at and destroyed. There is a system now of putting on a gang of men to examine the old logs right through the estate, even when there are no particular outbreaks of ants to warrant it, in the hopo that the nests will be discovered and destroyed before the ants actually begin to attack the rubber. It 13 a remedial measure, a very sensible one, and the expense is not at all heavy. Funaus. There are all sorts of different stories about the fungus; but the general idea seems to be that if you have an alert Superintendent, he can isolate attacks by means of drainage. A trench is cut right round the spot where the fungus is, the ground is then thoroughly dug up, all wood carrying any trace of fungus on it 1s destroyed and the ground is very freely limed with the result that they seem to be able to handle it quite easily. 1t does not seem to attack trees of over three years of age, Proeress on JuGRa ISLAND. Finally, Mr. Carey, can you tell me what progress has been made lately on Jugra Lsland ? We started work in August, 1996, and by the end of this year we shall have 4,000 acres planted, mostly in rubber, although a few hundred aeres will be in coconuts, We have not got anything more than 20 months old. We extended our programme from 2,000 to 4,000 acres and issued £42,000 of convertible debenture stock to enable us to doso. Over £100,000 was subscribed about 6 weeks ago and the prospects are very fine indeed. VULCGANIZATION TESTS IN PLANTA- TION RUBBERS. AT THE SOCIETY OF CHEMICAL INDUSTRY. Methods of Preparation more important than ages of trees. At the meeting of the London section of the Society of Chemical Industry, held on May 3, Dr J Lewkowitsch being in the chair, Messrs Clayton Beadle and H P Stevens described certain chemical and physical tests made on samples of rubber from plantation block, crépe and biscuit from young and old trees, and also a specimen of fine hard Pararubber. These experiments were made on the raw rubber, and on this material vuleanised either with sulphur only or with sulphur and mineral! mattor. These experiments, together with viscosity tests on raw and manufactured rubber, lead to the con- clusion that the method employed in coagulat- ing and treating the latex has a greater influence on variations in the quality of plantation rubber than any difference in the ages of the trees. —London Times, May 5. The Supplement to the Tropical Agriculturist THE WATTLE BARK INDUSTRY FOR CEYLON. We direct attention to the letter of MrA J Kellow which is prompted by a recent paragraph on the subject of the wattle-bark industry of Victoria in a commercial paper. We direct local Government attention to the need for some real enterprise in leasing, say, 1,000acre blocks of land on the Uva patanas for an industry like this, If such facilities were made known, there would pro- bably be enterprising growers ready to take it up. 100 percent. at the 8th year—even com- pared with rubber—is attractive enough; and this on a basis which is little above 50 per cent, of the current range of prices in London and Australia, a level that keeps fairly steady, Albion, Nuwara Eliya, May 20th. Dear %in,--The accompanying cutting, re ‘‘Wattle Bark,” contains much Interesting in- formation :— THe WartLe Bark INDUSTRY OF VICTORIA: A Market 1n LonpDon, The Master Tanners and feather Manufacturess of Victoria haye not been able to comply with the condition laid down by the Government that they should guarantee a fixed price per ton for all wattle bark grown by the Government during a term of years, in connection with the Association’s request that the Government should provide an adequate supply of home grown bark. The Association has forwarded a letter to the Minister of Forests, stating that while the members of the Association will always be willing to pay the highest price of the day for all bark for sale by the Government, they cannot guarantee any fixed price, At present tanners are paying fancy prices for bark, and many members of the Association have been compelled to reduce their output of leather for export solely on account of their inability to secure sufficient supplies of wattle bark. The Association considers that its request can be justified on sound business lines, as at £5 per ton it pays the land owner handsomely to grew wattle bark, and “there is practically, if not absolutely, no possibility of the price ever again going below £6.” Itis further urged that if in years to come, a3 a consequence of the planting of large areas with wattle bark by the Victorian Government, the supply should exceed the local demand, there will always be a sure and profitable outlet for any surplus ia London, where the present quotation for good Australian bark is £1010s. The Association therefore reiterates its request that the Government should largely increase the area of its wattle plantations. Considering the proved suitability of the upland patanas for the growth of Acacia decurrens— the variety producing the ‘‘ Wattle Bark” of commerce—there is a wide field open for the enterprise, if the Government could be brought to see the desirability of encouraging the move- ment, by either selling, or leasing, a few blocks of 1,000 acres each, for the sole purpose of Wattle cultivation, and thus bring more traffic to that portion of the Railway referred to by Mr. Ferguson at the last meeting of the Highland Tea Coinpany, as follows :— Mr Ferguson—said he would remember it when he went back to Ceylon. With others he had been pointing out to the Government the expense of the Haputale extension of the Railway, which was bringing in little or no traffic to the Government which had spent hundreds of thousands on abeut 15 miles of Railway. They had said: “Tf you cannot sell land, cannot you lease it on condition that the buyers should plant a certain area with trees for wind belts; and in that way you would get traffic for the railway and not at all affect the rainfall or anything of the kind,” (Hear, hear.) A few trees would even improve the rainfall. It would keep the rain on the ground better than patana. and Magazine of the Ceylon Agricultural Society. Many estates have already planted up Acacia decurrens—first for wind belts, or fuel supply, and latterly as a source of green manure. Occa- sionally one hears of a consigument of a few ewts. of bark to London, and because—as might have been expected—the experiment has proved a financial failure owing to the small quantity sent in, the verdict has always been against it as a possible paying ‘‘ege basket’; but any one might as well send a few odd Ibs. of—say tea— and expect to get its full value. What is wantod is a regular supply in appreciable quantities. In 1904, I wrote an essay (for the Tropical Agriculturist) entitled ‘* Wattle Cultivation in Ceylon,”—obtainable in pamphlet-form at the Observer office—in which I endeavoured to show what it might do if taken up ona sufliciently large scale: with an estimate, based on actual experience, of the quantity of bark procurablo per tree; and taking £6 in Colombo as probable value per ton, showing a profit of over 100 per cent in the Sth year, whereas present quotation is £10 10s per ton in London.

LOCUSTS ON LAWNS: A CURE. May 21st. Dear Srr,—A species of small locust or grass- hopper is very destructive to lawns in the Ceylon low-country. Most people, who take pride in having a lawn in the garden, find these pests most troublesome, and on the Colombo Golf Links, L believe, they prove to be a great pest. 1 send you this cutting, which I have had by me for some time, and I feel sure it will be found worth trial by the Ground-Secretary of the Colombo Golf Club ; whileit is worth pub- lication in the Tropical Agriculturist, as of use in all countries where such locusts are troublesome: What has come to be knownas the ‘Criddle mixture’ is giving most satisfactory results in dealing with grasshop- pers on the ranches of both the United States and Canada. The mixture is composed of half a barrel of fresh horse droppings in which is mixed a pound each of salt and Paris green. If the horse droppings are not fresh the salt is dissolved in water and mixed with the manure and poison. When this mixture is scattered freely about where the grasshoppers are abundant they seem to be attracted to it, for they devourit readily and are poisoned thereby: Dr. James Fletcher, Entomologist for the Dominion of Canada, cites an instance where this mixture had been scattered freely around the edges of a field, and states that this particular field stood out as a green patch in a brown plain, asit was situated in the midst of field where no- thing had been done to destroy the grasshoppers, This ‘Criddle mixture’ now seems preferable to the poisoned bran remedy thathas given, and still continues to give, beneficial results, forit is less expensive than the latter and less likely to poison other animal life. The grasshopper in the States and Canada is a species of Melanoplus; I do not know the Ceylon species,—Yours truly, L. L, C, 591 PLANTING METHODS IN B.C. AFRICA. Nyasaland, April 2nd. DEAR Srr,—I see a letter in your issue of January last, written from Mlanji and dated lith November, criticising H. B.’s methods of cultivation, &c, My reply to the gentleman who sigus himself ‘‘ Planter’ is: ‘‘Would the power the giftie gie us,” as Burns put it, to enable ‘+ Planter’ to see himself as others see him. Your remarks, viz, that ‘‘ Planter” does not want Ceylon men to come to Nyasaland is quite true; but it would do him good and others too to have a Job of Ceylon here, although there might be the danger of ‘‘Planter” losing his billet which is evidently the crux of his whole letter. Plenty of men in this country have started planting on less than even a few hundred pounds of capital—with the assistance of the Cottou Growers’ Association alone, and have done well, too. Of course they had the land. Ceara rubber has been in Nyasaland growing like a weed in the bush for 20 years and more, and many, who tried it, could not make it pay any more than Ceylon planters did, and have dug it out. New methods of tapping may yield better results, but this remains to be proved. **Planter’’ speaks of drink being the ruin of men here (he might as well have mentioned drugs, too); this takes place all the world over un- fortunately. ‘‘Planter’ wants figures regarding the yield of tea, &c. ‘There is no need for this request seeing, as he says, he has been 5 years in Mlanji, for he should be in a position to supply them himself ; and I am sure all will be pleased to see those tigures published. A great drawback to this country is the want of the experienced Visiting Agents system, the same as exists in Ceylon. Company Managers are the men who usually visit and report on estates in Nyasaland and their visits are made perhaps once in a year and perhaps not for two years, so that Superinten- dents of estates do absolutely as they please. The result is reckless expenditure of public money, as far as Companies are concerned, I have known a man put in charge of an estate here who, without consulting his neighbours, raised the pay of ordinary labour to more than twice the amount paid by others—for no reason whatever except to impress upon the natives that he was a big white man. Of course, the money was not his own. Unfortunately this throwing away of money is not confined to new-comers, but to men who have been in the planting line for a long time. So itis not to be wondered at that ‘ Planter” says £1,500 to £2,000 isrequired to start planting in Nyasaland, I have known men here start paying 3s. per month, the usual rate for village labourers, and keep these men on, raising their pay to 6s. because they were too lazy to teach other men pruning. How would Ceylon planters fare if they were too lazy or indifferent to teach thoir coolios pruning ? I guess they would get their walking ticket, 592 A few hundred pounds would enable any man to start in Nyasaland. The purchase of land or lease is a mere trifle and the rest of his capital, if employed to grow acrop of tobacco, he can double in a year to 18 months’ time, getting spot cash for the leaf from the Imperial To- bacco Co. in Blantyre. Actual costof opening 100 acres of landin Nyasaland for coffee in 1898 was as follows :— Felling and clearing 160 men.

Noestimate is given for the planting of chillies as they were simply dibbled in and the cost was absorbed in the other items of expenditure. Labour is a trifle dearer now than it was in 1898, but the above estimate is near enough and quite reliable. Of course the cost of opening and bringing an estate in bearing may be any- thing from £2 or £3 per acre to £20 or more en- tirely depending on the man and his purse. CRITIC. CARBON BISULPHIDE ON ESTATES. We received by a recent mail from home an en- quiry on behalf of a manufacturer, in connection with the rubber-growing industry, as to whether and in what ways carbon bisulphide will, in fature, be largely used on plantations. Onour enquiring of Mr. M Kelway Bamber, that gentleman is good enough to tell us that carbon bisulphide is used for destroying white ants, and attempts were made to have apparatus for its manufac- ture erected in Ceylon and the Malay States. It is very efficacious, but it is difficult to find the nests of the ants in rubber clearings as they are below the ground level or under tree stumps, &c. Mr. Bamber, however, believes they can be found if carefully looked for. About 1 or 2 oz. of CS2 is poured into the nests and all exits closed ; the vapour, being heavier than air, sinks down through the nest, destroying the ants en- tirely. ‘This was referred to by Mr. E V Carey in our interview. If cheaply produced, its use might be largely extended in tropical coun- tries; but at present Shipping Companies do not readily carry it even as deck cargo, owing to its poisonous and explosive nature when the vapour is mixed with air. The Supplement to the Tropical Agriculturist JAPANESE SYSTEM OF CHARCOAL MANURE is one which ought to interest all agricul- turists, in the tropics as wellas elsewhere. We direct attention, therefore, to the letter of the Yokohama Nursery Co., which describes it and the points in which it differs from a simpler sys- tem it resembles. We shall be glad to hear the experiences of any practical planter who takes the method up, or meanwhile any criticisms of it based on practical knowledge of manuring (tea and rubber, especially) already acquired, 21-35 Nakamura, Yokohama, April 26th, 1909. Dear S1r,—While questions of scientific fertilisers are under discussion, it may not be amiss to report what is doing here in Japan, in that matter. We havea method known as the “Oyaidzu system of charcoal manure” which is highly recommended by Mr Ikeda Kenzo, the president of Japan Agricultural Society, and is now widely practised. This is nothing but charcoal made ofstraw, or any other combustible rubbish materials, mixed with ordure or other manure which is claimed to be very efficacious and produce good crops. One-third is said to be sufficient for the purpose as the charcoal resists against actions of weather and retains power longer than any other way, such washing away, blowixg off or evaporating, etc. This may seem like the old way of ash _ utilisa- tion, but what differs is how the charcoal is pre- pared. Great care being taken not to allow the material to burn but make it smoulder in a pit by adding little by little slowly so as to keep flames down yet the whole turn into charcoal with- out any portion remaining unburnt. 80 per cent. charcoal itis said can be made out of the material burnt. If too much be reduced into ash, the per- centage will naturally be less. While the char- coal is stiJ] warm, liquid manure is poured over to a certain degree of moisture when it is ready to be stored for future use. It has no offensive smell and is very convenient to handle, especially where supplies of manure are scarce or transport dificult. This may be worth while for your planters to try and see what benefit there is in it. To sum up, the points are that 80 lb. charcoal should be produced out of every 100]b. material burntand while the charcoal is still warm manure must be sprinkled over.—Y ours faithfully, THe YokouamMa Nursery Co., Lrp.

This is thelatest inven- tion in tapping knives, it is claimed, and its chief feature is that recurrent expenditure is reduced to a minimum. The neat blade with four cutting ‘edges can be reversed in a minute and the re- maining sharp edges employed in whatever dir- ection the operator is paring. It cuts right and left hand, ‘‘ Puli or Push” without any altera- tion or adjustment Itcannot possibly choke aud requires no sharpening: itis the simplest knife on the market. Requires no adjustment, Perfectly safe. and Magazine of the Ceylon Agricultural Society THE NORTHWAY TAPPING SYSTEM. A SERIOUS DISCOVERY. It will be remembered that about six months ago there were rumours that anew system of tapping rubber trees had been discovered, for which there were claimed mary advantages over the various styles of tapping then in vogue, The inventor, Mr. Northway, supported by experienced Ceylon planters, stated that it was to be commended for simplicity in working, less likelihood of damage to the tree and increased work by the tappers, and these were among the powerful reasons for giving the system an exhaustive trial. If there were no other reason, the fact that our rubber estates in the future would, by the new system, require 75 per cent less cooly labour for tapping was in itself a sufficient justification for the inventor’s clever idea being thoroughly exploited ; and we believe that in many in- stances the experiments, which have been macte up-to-date, have realised expectations. We have then learnt with more than ordinary regret that the results of trial upon some properties have disclosed drawbacks and disadvantages which appear to imperil the future and assured success of this mode of extracting rubber latex. It appears that in certain trees which are exceptionally rich in latex at this season of the year the incisions caused by the pricker close up prematurely, and before the flow of latex from the cambium layer has ceased, with the result that the latex flows down the tree between the cambium layer and the bark, where it formsa pad of coagu- lated rubber, much resembling a rubber patch which is used for repairing the inner tube of a motor car tyre. This pad swells and causes the bark of the tree to burst away, the pad adhering firmly to the wood, which, with the cambium, becomes discoloured and black, and may prove the fore-runner of decomposi- tion of the wood itself unless the pad of rubber and the bark are carefully removed. Perhaps the most peculiar phase of this state of affairs is that these breakaways occur upon a small percentage of trees, and those which are particularly vigorous and robust and growing upon rich, low-lying lands, where undoubtedly the secretion of latex is much _ greater than upon the hill sides. Wo may mention that the trees on which this has taken place were pricked about six weeks to two months ago and it is only within the Jast three weeks that these unfavourable symptoms have developed. We sound this note of warning in order that all rubber planters (and they are many), who are experimenting with the Northway System, may carefully watch their pricked trees ; and—if they have discovered these danger spots of sub- cortical pads of coagulated latex—take such re- medial measures as they may consider necessary. Should this unsatisfactory state of affairs mani- fest itself generally, we fear that the Northway system will stand self-condemned. The occur- rence of these rubber accumulations under the bark would suggest that for any but the slowest- flowing latex-bearers there is the danger of the (6) 593 latex not being able to flow sutticiently freely through incisions made by the pricker and that thesystem is therefore most suitable—or suitable only ?—for the youngest trees, where a free flow isnot yet fully established, or those few older trees which promise never to give rich yields, The wider incisions of the knife, which, with subsequent paring, have given perfectly re- newed bark, may well—after the above dis- coveries—return again to a popularity which had only been temporarily shaken. In conclusion, in reply to Mr. Wiggin, we are quite ready to learn; but the system has not yet been tried nearly long enough yet for even its warmest advocates to commit themselves wholly either! And we under- stand the possibility of mistakes through ex- cess of zeal is less with the older systems than with this new one that starts work on three and four-year-old trees in Ceylon. Lindula, May 24th, Sir,—The coagulation of the orifice made by the pricker and sequence as described by your article can simply arise from one thing : in- sufficient spraying—a result that must arise without supervision, Does any one imagine Ramasamy carrying and using water if he can avoid it ? Why he would actually starve him- self if he could exist without the trouble of eating ? It is only hunger that makes self-exer- tion evident. ‘To the present-day cooly work is no pleasure. Neither, since Companies came into existence, does he take any interest in his estate as a domicile. Make and clear is the order of the day as he sees the Agent is to sweat for shareholders, so is his ‘‘make for himself.” Take private properties now (there are some). The life of the labour force thereon is an Eldo- rado, No impossibilities forced on to the Super- intendents. No impossible estimates to keep up to,and only donein many instances at the expense of the cooly. This isthe predominant factor of the discontent and miserable state our labour force has got into, want of sympathy and’ co- operation. The Straits appear to have learnt their lesson and labour seems to flow over there freely enough. Here, Tempora mutantur et nos mutamur in itis and not to our advantage or welfare.—Yours, &c., EK. R.

Srr,—In reference to your article on a defect alleged to result from the new tapping system, I have not a single tree here that shows any sigus whatever of any disease since [ started new tapping. There is nothing new in pricking. We have used prickers here for the last five years and 50 per cent. of other estates have conti- nuously used them for about that time.— Yours faithfully, CHAS. NORTHWAY. II. Glendon, Neboda, May 28th. Dear Sir,—I see in your leader in the Observer of 22nd, mention is made of injury done to rubber trees by the incisions of the pricker closing up prematurely and causing the latex to coagulate inside the tree and burst the bark. Inoticed this some two years ago on a 15-year- old tree growing on a Aili and tapped with an ordinary knife and never pricked. | put it down to tapping in February (avery dry month) and when the leaves were off. However, it only occurred in this one case and the bark was cut away and subsequently healed up. Judging from what has been written about the new tapping system, it does not appear likely to supersede aring though it may be suitable, in certain loca- ities, for trees 3-4 years old.—Yours faithfully, R. J. BOOTH. IV. Kalutara District, May 29th. DrAR Sir,—The phenomenon, which has arisen with the Northway system oftapping that you refer to in your leader of the 22nd, I understand, has only been noticed on old trees. It would be interesting if you could get Mr Northway to publish figuresin support of his statement that equally good results, at less cost, can be ob- talned by his new system, as by the one usually in use. They should, I think, take the following form ;— (1) Quantity of rubber obtained in 1908 off a specified group of trees, giving average girth, number vofdays tappedand cost of tapping. (2) Quantity secured this year, from same group, by the newsystem (and anticipated yield for year), with number of days tapping and cost. Mr Northway should be easily able to provide you with these figures and it would give other users a line to go on and show them what can be done. Itis, I think, important that the average girth and approximate age of the trees should be given.—I am, yours faithfully, RUBBER-GROWER., V.. In Repty to MR Wiecrn. Ruanwella, May 31st, 1909. Dear Sir,—fe Mr Wiggin'’s letters on the New System of tapping, they are polite—to say the least of it. He regrets the lack of brain power in rubber planters tosee the damage done by what he calls butcher's knives, but he seems himself to lack the brains to see the damage the blunt prickers can do. He does not really understand (judging by his letters)—the vascular system of the Hevea tree; or he would understand the great often- times hidden damage which is done to the tree by the new system. I would advise him to visit his friend Mr Northway’s estate, or any other where the tapping has been done for two months, and take off a piece of the pricked cortex right to the wood and then write to the papers the result. The Supplement to the Tropical Agriculturist There isa proverb which says; ‘‘ Don’t teach your grandmother to suck eggs’’ ; and certainly rubber tapping is not taught in Dimbula, and I for one don’t consider that a visit now and again to the low country, to see a few rubber trees tapped, is sufficient to entitle Mr Wiggin to teach his brother rubber-planters,— Yours faithfully, LOW COUNTRY, RUBBER IN COLOMBIA. The following curiousadvertisement appeared the other day in the London Times :— RUBBER PLANTATION.—Offer at 16s of 500 £1 fully-paid Shares in dividend earning, old-established Company. Capital £100,000. Estimated yield of rubber this year, £12,000, increasing to £40,000 on further maturity of plantations. | An enquiry brought a letter to the following purport :— “ As requested we send you particulars of the 500 £1 fully paid shares in the Colombian Rubber Company offered at 17s 6d or at 16s (£400 if taken in one lot. The Company having now reached the dividend-earning stage the most modern machinery for preparation of the rubber was shipped to Colombia last December and Mr. Sloan left early last month forthe estate to superin- tend the preparation and consignment of from £10,000 to £12,000 worth of rubber part of the proceeds of which will be applied to the payment of a first divi- dend of 8 per cent or 10 per cent and concurrently with its declaration application willbe made for a Stock Ex- change settlement in the shares. On fuller development of the resources of the estate and on erection of the saw-mills the Company will be able to pay perma- nent dividends of not less than 20 per cent, for rubber can be produced on this estate at a lower cost (?d per lb.) than in any other part of the world.

Forest land covers 150,000 acres with wild rubber trees (Castilloa Elastica and Sapium) averaging five to the acre, which are ex- pected to be tapped gradually and to give 5 1b. rubber per tree. There is said to be £10,000 to £12,000 of rubber ready for shipment, and I must say the growth of castilloa trees in an avenue, eight years old, shown in one engraving is very good indeed. The investment ought, therefore, to be a promising one for any person caring to invest in South America. Alto- gether 105,731 castilloa trees have been planted and are from 1 to 8 years old. Manioc, banana (a crop every 8 months), but are used to shade the young rubber trees; also Abaca, a new product, yielding a fibre like Manilla hemp ; Mahogany trees are common in the forest.

We direct attention to the article which we here reproduce. Mr. Sandmann, the writer, was sent out by the German Colonial Office to the East in 1906 and to Brazil in 1907 to study the rubber industry. In the September num- ber of the Zropenpflanzer a long abstract of his official report appeared, and Dr. 8. H. Berkhout replied to this in the Febrnary number. The tenor of Dr. Berkhout’s paper was to show the difficulties Brazil has to encoun- ter in producing rubber, and her inability to compete as regards cost of production with the East. He concluded: ‘‘Just as South America failed in the competition against cultivated - cinchona, 80 will its wildrubber be unable to hold out against the plantation article.” It will be seen from Mr. Sandmann’s reply that he differs from Dr. Berkhout considerably. An article with the above heading from the en of Mr. D. Sandmann appeared in the ropenpflanzer for April. Mr. W. J. Gallagher, M.A., has kindly translated and annotated it for us as follows :— WILD v. PLANTATION, “ Before I had visited the Amazon District I was of the same opinion as Dr. Berkhout, and. in my report on the rubber; industry in Ceylon I expressed the view that it will be impossible for the collection of rubber in the primitive forests to compete with Plantations, Dr. Berkhout built on a very certain found- ation when he assumed tho conditions im Surinam (Dutch Guiana) to be similar to those in the Amazon region. I have reached an opposite conviction, although [ have never been to Surinam, but have been informed of the local conditions from Huropeans resident there for many years, Hspecialiy do the political, clim- atic, and agricultural conditions differ consider- ably from those in the Amazon. ‘Dr. Berk- hout says: ‘In the future it will be absolutely necessary for the owners of cultivated rubber for the production from Brazil to decline.’ I am of acontrary opinion though admittedly, with a much larger amount of rubber thrown on the world’s market, the present high prices, | which give profits far beyond the normal, will not be reached. With cheaper prices suflicient to give well-cultivated plantations a normal profit so many new applications of rubber would arise that not only the present production of 70,000 tons but even several hundred thousand tons per annum would be consumed, The main- tenance of the Brazilian output isa danger only to estates which produce their rubber dear and of poor quality. ‘Dr. Berkhout agrees with mo that1 kilo (2.1/5 lb.) of rubber can be produced easily on an estate for 2 marks (2 shillings).” [This is equivalent to 11d per Ib. At least one estate has to my knowledge laid rubber down in London at this outlay. Apparently the cost f.o.b. at the nearest port is meant. Inthe F.M.8. this varies from slightly under 10d to over 13d. The higher figures refer to estates producing 595 small quantities, and are of little value for purpose of comparison.—W. J. G.] ‘‘When Dr. Berkhout states that the cost of production at the present day in the Amazon area is 5 marks per kilo (2s 33d per lb.) 1 must emphasise, as I didin my report, that these 5 marks are not money in the German sense of the word, but re- present so much provisions and implements of production which at the present time possess so high a nominal value in the rubber producing areas, but which under changed conditions, es+ pecially if produced locally, would fall consider- ably. There isno ground for doubting that the provisions and luxuries consumed in the Amazon area could easily be produced there. Indeed the soil and climate are such that these articles of consumption could be produced more quickly and easily there than in most other regions. ‘‘In the present prices of rubber labour is paid so high that all cultivation of food products is left aside. After four to six months’ work of a 6 to 7 hour day, a tapper is able, notwithstanding the high price of neces- sities, to support himself, and with carefulness he can even eave something. This is also the reason why the emigrants from Ceara will not go, as Dr. Berkhout thinks they must in the future, to districts in South Brazil where, to support themselves, they must work not 6 to 7 hours a day for four to six months, but a 10- hour cay the whole year round. Further, the Ceara people profer the free life in the forest to that onthe estates (cocoa and coffee) of Sao Paulo or Pernambuco. ‘* With the PRODUCTION OF FOOD CROPS in the Amazon region the conditions will imme- diately change, because not only the male labourers but their families also will immigrate there. This would not alone lower the cost of the journey but the working strength would be con- siderably increased. Besides, the Seringuero (rubber-tapper) has no yearning after big towns, If the Ceara natives who immigrate to the Amazon district worked their day of 6 to 7 hours the year round, instead of for 4 to 6 months as they do now, the production would be certain, and the workers would still have shorter hours inthe pleasanter Amazon area (pleasanter to them) than on the estates of South Brazil, ‘*To decide the question it is necessary to have studied the habits of these people on the spot. Only when one has convinced himself how satisfied with his life the Seringuero is, and how he sees the dolce far mente as the greatest object of his labours, can one understand that only necessity will make him work more. ‘‘The variations in the quantity of rubber exported annually also confirm this. I agree with Dr. Berkhout that only in the following year does a fall in price have an effect on the production. When the price for years steadily fell from 48 3d and in 1902 reached its lowest at 3s 2d, only then did the Seringueros, when need compelled them, do more work ; and the expression of this is found inthe export of the year 1903 with 31,094 tons against 25,430 in 1899, ‘‘T have already shown in my report (abs- tracted in Tropenpflanzer in September, 1908) 596 that the production of food in the Amazon district would reduce the present cost of collec- ting and preparing 1 kilo of rubber from 5 marks (=5 shillings) to 1°60 marks (=1s 7d.) ‘* A comparison of the returns in rubber from a hektar (=22-5 acres) compared with those from the same area on an estate is not possible. The value of a hektar of primitive forest to that of an estate often is as 1 to 1,000. Large areas of primitive forest can at the present day be obtained in the Amazon region for one marka hectar, that is for the cost of the measuring only. Beside rubber the Brazilian forests yield many other valuable products. Dr. Berkhout is in error when he thinks that, because “Terra firma” (the area which is not flooded when the river is at its height) is often far from the banks ofa river, it must likewise be far from the areas where the rubber is collected. It is true that the areas which Hevea prefers are not always bordering the ‘‘Terra firma,’ but the suitable land for the raising of foodstuffs is exactly the ‘Terra firma,” and it can be cultivated when the flooded areas cannot be worked. ‘So long as rubber brings a high price, no one thinks of improving anything, but WITH A FALLING PRICE the need for improvement and better work would make itself felt and would be met. “The Brazilian Government compared with the Colonies of England, Holland and other countries has yet done little, it is true, in the way of experiment stations and the like to improve land industries, though even here it cannot be denied that Brazilis making progress. “Dr. Berkhout’s view that a decline in the price of rubber will lead the people to plant cocoa and other cultivations is to be accepted conditionally. If through high cost of living and dear labour the exploitation of rubber muststop, so will the cocoa estates, etc., inthe Amazon region with equivalent rates of labour pay be just 2s little able to withstand the cocoa, etc., estates of Asia and Africa. “The comparison withthe cinchona industry of Java, which defeated that of Bolivia, would be applicable only if the poorly remunerative cin- chona of the Bolivian forests was comparable to the highly remunerative rubber of Brazil. Ifa better paid and more easily worked product than rubber was available in the Amazon, the natives would turn to it from the rubber industry, But as long as no easier way of making a livelihood is possible, the natives ofthe Amazon area must give their attention to rubber.” ‘*T must still maintain my conviction that the production of rubber in the Amazon region will be a thing to reckon with in competition when the plantation areas are in full bearing. It is on this account necessary to consider, before opening up new estates, how far these will be capable of yielding a profit in the competition in production and price with Brazil." It is interesting to note in the foregoing that a fall in the price of rubber, within limits of course, will increase the Brazilian output, and further the latent capabilities of even the present labour force,—Matay Mat, May 20, The Supplement to the Tropical Agriculturist THE CONSERVATION OF LAND AND WATER. A large proportion of the rain, which falls on the land, is practically lost to the cultivator by its flowing over instead of into the soil, But apart from this there is a far greater loss due to erosion, which is responsible for carrying away immense quantities of soil material, partly in solution, but chiefly in suspension. The value of this loss is not easy to compute, but it will be readily admitted that it must be very great when it 1s recognised that the wash consists of surface soil which is the richest part of it—being, indeed, the ‘‘cream” of the land. The opening up of new lands and the exposure of new surfaces, to the action of falling and running water goes to increase this loss. When rain falls, a part of it evaporates directly, a part flows away and joins the streams to finally find its way to the sea, a part soaks in to the soil and sub-soil either to emerge as springs, &c., or remains underneath the surface to serve the requirements of plants if it is not allowed to be drawn up and evaporated. The amount of water which runs off depends on the slope of the land and the nature of the growthupon it. Forest vegetation, a close growth of grass, on a deep friable soil, will so check or absorb the flow that there will bea minimum of loss of moisture to the soil. The chief scurce of our prosperity as a colony is the soil; it is the duty of the Government to encourage the con- servation of the soil and its improvement for the - immediate benefit of the planter and native cul- tivator, and the ultimate welfare of the Colony. The most valuable asset to the agriculturist is the water that falls on the land and permeates the soil where it can aid in the production of crops. It is, therefore, also to the interest of the Government to see that this water shall be so controlled and conserved as to yield the greatest benefits to the cultivator of the land and even- tually to the whole colony. It is on cultivated land, however, that the evils of soil erosion begin ; while it is clear, therefore, that the remedy must begin on these areas, it is the duty of Government to see that the remedy is prescribed and applied. The course to be adopted is in some particulars at least quite evident :— a. Deep cultivation and good tilth on culti- vated areas. By this means the maximum of rain- fall will be absorbed and the minimum allowed to run off the surface. This treatment of the land will, moreover, be an advantage in other respects, inasmuch as it will assist in drawing up plant food to within the reach of the shorter rootlets and also carry down humus to feed the deeper roots. 6. Deep underground drainage (preferably tile drainage) on flat lands and tenacious soils where the ground water moves sluggishly. This mode of drainage is little known and less practised in the East, but under the conditions referred to its action is most important in helping both soil and subsoil to crumble and disintegrate and through the mechanical and chemical changes and Magazine uf the Ceylon Agricultural Society. induced to become friable and susceptible of retaining the right amount of moisture for plant growth. The indirect result, however, is the reduction of surface flow and erosion when rain falls. ¢. Contour Cultivation on Rolling Lands.— The plough-furrow (where ploughing is done) and crop rows should be carried round the slopes in such a manner that each furrow or row will lie level, so that there will be no tendency for them to be widened into gullies by storm water, but rather to close runnels and form receptacles in which water may lodge till soaked into the soil. d. Inhilly land contour cultivation should be supplemented by ‘‘ balks” or ‘* breaks,” i.¢., strips of grass separating cultivated stretches, and these should be level like the cultivated portions. The tendency would thus be towards the formation of a series of terraces. e. On very steep land it is. advisable that agriculture should give place to silviculture which might be combined with grazing. On mountain heights, forests should be retained and extended, for, as the Spanish say, the mountains are the mothers of waters, and every lofty range being a ‘‘ Sierra Madre,” and the forest trees acting as distributing agents, and reducing erosion and wash to a minimum, It would appear from what has been said that a scheme of classification is desirable, so that lands of different elevation and situation may have each the most suitable crops assigned to it—whether timber, grass, shrubs, grain crops and so on. But to carry outa policy such as is here indi- cated, individual and collective action is neces- sary. For educative purposes it is necessary that information should be widely diffused as to the magnitude of the loss by erosion, the facility with which it could be checked, and the cer- tainty that the result will be profitable to each individual while serving the general weal. In- dividual action could, of course, be confined chiefly to improved methods of cultivation, as indicated above, with a view to conserving both soil and moisture, while more extensive operations with the same object in view can only be carried out by co-operation, The evils resulting from the neglect of the course prescribed is amply exemplified in this colony, where, indeed, afresh source of trouble has arisen through the damage done by the silting of paddy fields. The duty before the agriculturist as well as the Government is clear, and we trust that we have, to some extent, succeeded in arresting their attention and proving the necessity for conserving soil and moisture by every means in their power. CULTIVATION OF THE SOIL. With reference to the subject of the ‘‘culti- vation” of the soil and the very useful letter of “Delta” in the Tropical Agriculturist, in drought-affected areas, and more especially where the soil is very stiff, as on either bank of the Deduruoya, where the soil is chiefly alluvial, too much time and money cannot be expended in keeping the surface soil in a fine state of tilth. The suggestion is unpractical to stir the surface soil after every period of 597 rain, though, of course, it will be very bene- ficial. The least coconut planters with a stiff soil to work could do, is to thoroughly plough or till the soil one year, and in the following year harrow it, or break the clods thoroughly with mamoties, On a free, sandy soil, the latter operation is not an absolute necessity, as the surface soil does not cake. On estates that I know of on either bank of the Deduruoya the growth of grass is so rank that aeration of the soil, so necessary tu improve its mechanical and chemical condition, cannot take place. My advice has always been to turn over the surface soil, which will mean green manuring as well, though not with the now fashionable Leguminosz, and to lime it. This latter treatment will not only convert the luxuriant herbage into humus, but will set free all the latent and dormant elements of fertility in such soils, and will also improve its mechani- cal condition. Those with a book learning of Acricultural Chemistry say ‘*‘Do uot lime the soil oftener than once in 3 or 4 years, as it exhausts the soil.” This is, of course, true where enor- mous quantities of lime are used. My advice has been to lime after ploughing every alternate year with moderate quantities ofit. The rich growth of grass that will follow should be wee- ded with mamoties in the dry weather, when other works are not possible, and the grass be allowed to remain on the surface to act asa mulch. The weeding will also stir the surface soil and make that too act as a mulch. RUBBER PRICE CONDITIONS. The topic of the utmost interest in the India- rubber industry today, and that which is most considered, is the present and prospective price of crude rubber, Whether the manufacturer be located at Malden, Manchester, Mannheim, Melbourne, Menin, Milan, Mjondalen, Montar- gis, Montreal, or Moscow, the question is ever present, as one which must be take into account in planning every detail for the future, This is a fact which makes the whole rubber industry akin, for the price of rubber everywhere at any moment practically is the same, while the same uncertainty exists as to what the price may be tomorrow. The producers of rubber and the traders in rubber have troubles of their own in relation to the same subject, but here we shall treat more particularly of the manufacturers, Where rubber prices are made, or how they are made, are questions not now ‘pertinent to our purpose. The uncertainty of prices is the thing, and what the consumer of rubber can do about it. Low priced rubber is not so essential. When every consumer of a given grade of rubber must buy it practically from the same source, and it costs them all precisely the same figure, they are all on the same footing. Whether the cost is 50 cents or $1 a pound, or more, would be immaterial—if permanent prices could becounted upon. But they cannot. The average price at New York of fine up-river Para rubber during the year 1902 was 76 cents; during 1905 it was $1°284; since then it has been less, the figure for 1908 declining to 93} cents. This year, so far, the price for this grade has kept in the neighbourhood of $1°20, hen itis 598 considered that the difference between the highest and lowest year prices here quoted amount to no less than $1,157:42 cents per metrical ton, and that these fluctuations usually occur without warning, the buying of raw rubber by consumers approaches almost a speculative basis. The producers of rubber in the Amazon region, far from satisiied witha condition under which they have no say in fixing the market price of their produce, have determined upon a course of action, in which, with the help of the government and of a_ great bank, they mean to hold their rubber whenever prices are not high enough to be attractive. Now the holding of rubber anywhere is an expensive practice, when storage costs are considered, insurance, interest on advances—and the ine- vitable shrinkage in weight. Itis well enough to speak of rubber as being a modern neces- sity, but there are limits to what people will pay, even for necessities, and manufacturers would have to halt somewhere in the matter of paying advancing rates on rubber, even were the Amazon region the world’s only source. There would be an inevitable check to rising prices, due to increased production and the hesitation of consumers to buy, after which the banks would have to unload, with such results as followed Vianna’s state aided rub- ber ‘‘ corner ”—a fall to half the former prices aud loss to everybody concerned. The India Rubber World, a dozen years ago, printed an article on ‘‘ What Vianna Did for African Rub- bers,” showing that his speculative ‘ bearing ” of the market for Para rubber opened the way largely for the increased use of African grades. Nowadays, African rubbers having won an established position in the industry, though now apparently falling off in the rate of pro- duction, an important new source of supplies has been developed—the Eastern plantations, the product of which (Hevea) is better cal- culated than even the best Africans for sup- planting the Amazon rubber in the industry. Without meaning to advise our friends on the Amazon, it would seem that their best interest lies, not in forcing up prices to an artificial level, but to so improving their business methods as to enable them to sell at a profit at even lower prices than at present. Their devotion to any policy gives the plan- ters of Ceylon aud Malaya, backed by un- limited European capital, the very encourage- ment which they want and most need. The Eastern planters have it in their power to appeal strongly to the consuming markets in the matter of guaranteeing prices for longer periods than have ever been known in the trade before, and we shall be surprised if this does not strengthen the demand for their pro- duct,—Jndia Rubber World, May 1. ee ee INTERPLANTING RUBBER WITH COFFEE. Dr. Cramer, an agricultural expert has de- livered a lecture to a gathering of planters at Serdang, in Deli, on linking coffee growing with rubber cultivation. He dwelt on the Robusta variety of coffee, which is being The Supplement to the Tropical Agriculturist favoured by plantersin Java. The point was made that, in Europe. Robusta coffee fetched as good prices as the Santos variety from Brazil. In his opinion a_ large stretch of country in Kast Sumatra is admirably adapted for Robusta coffee as a catch crop on runeee estates. —Straits Times, May 28. TAPPING YIELDS. Mucu LArGerR BY THE OLD METHOD. Mr W H P Dias, of Wawulugala, Horana, writes to the local ‘‘Times” of the relative results obtained on that estate from 225 trees of 5-year- old rubber tapped in the old half-spiral method of paring, and 225 trees of the same size, age, and in the same field tapped by the Northway prickling system :— ““] began tapping by the Northway system on the 17th of April. To this date I had secured 63 lb of dry rubber from the 225 trees I marked off in January and tapped for 47 days by half- ee system. Below I give the results in tabu- ar form :— Dry rubber Dry rubber Ib. lb. by old by Northway Tapping No. of method method Period. days. from 225 from 225 trees. trees. 47a 63 not tapped April17 to 8rd May 14 22 11 iday 11 to 27 15 235 9 Total 110 2¢ a January 16 to 30, February 1to 8, March 8 to 29and April 2 to 16. ‘* By the old method, Ihave secured 110 Ib of dry rubber in 76 days, and I still have about half of the bark left on the side I have tapped, and there is the possibility of my securing more than 110 lb of rubber trom the remaining bark on this side. Whatever it is, I am certainto obtain 220 lb of dry rubber from these 225 trees for this year. Whereas from the trees tapped by the Northway system, I have secured only 20 lb of dry rubber, and [ may obtain another 20 lb at the most for the other 30 tappable days in the year which will make 401b for the year. Of course, these trees were not manured year after year like Mr Northway’s. Last week I went round, passing several well-known estates at Neboda and Tebuwana, the centre of rubber, and I found that many had taken to the North- way system, but that now most of them were giving itup. So I am convinced of what Mr Harrison says; it is safer to walk on known ground than try to flyin unknown places. RUBBER PLANTING IN NEW GUINEA. Mr. H. A. WickHam’s 10,000-acrE LrEasz. Mr R Tweed Baird, the partner of MrH A Wickham (the well-known Brazil rubber pio- neer) in the 10,000-acre lease in New Guinea to be taken over by the Mombiri Rubber Planta- tions, Ltd., was on his way out to Papua by the ‘‘ Macedonia ” which was in Colombo on May 28th. The capital of the company is £52,500 and among the directors is Mr C de Winton, who is also director of the Castlefield (Klang) Rubber Company, Cicely Rubber Estates, Ltd., and Hidden Streams Rubber Syndicate. and Magazine of the Ceylon Agricultural Society. A FRENCH ESTIMATE OF PLAN- TATION RUBBER. The conclusion reached by M. Edouard Payen, in an article on rubber which he contributes tothe Heonomiste Frangais, is that the present situation is not permanent, and that itis pro- hable that in ten years’ time it will be necessary tu turn towards the plantations of the Far Kast when we wish to foresee the state of the rubber market, instead of to Brazil and Africa, as is the case today. Itis almost certain now that there is no lack of thisarticle to fear; but if, on this side, security is obtained, it is lostin the countries for which the exploitation of the wild rubber is a source of riches. These countries must prepare themselves, while there is yet time, to support without too much inconvenience and hardship the consequences of the competition of plantation rubber. The writer mentions that Professor Perrot, of the Ecole de Pharmacie of Paris, recently esti- mated the land under rubber in the Far East as follows:—Malaya, 186,000 acres; Ceylon, 182,000 ; Java, 60,000; Sumatra, 32,000; Borneo and New Guinea, 10,000 ; India and Burmah, 30,000 acres. Specialists think that if, about 1916, the Far East produces 15,000 tons of rubber, planters should count themselves very fortunate,— Ld ( Express, May 14. COPRA FROM THE DUTCH EAST INDIES. The British Consul at Amsterdam, reporting on the trade of that neighbourhood, remarks : —Copra has sprung into prominence in the Netherlands in recent years. The Notherlands consumed in 1908 about one-sixth of the world’s production, much of which comes from the Dutch East Indies, Most of the copra for the Dutch market comes to Amsterdam, where it is manufactured into various kinds of oils, edible as wellas for the manufacture of soap. In 1906, 1907, and 1908 the following quantities were imported into the Netherlands: 47,689, 52,632 aod 71,432 tons respectively, of which the share of Amsterdam was 38.867, 46,744and 57,702 tons respectively. Great care istakenin the Dutch | East Indies to secure a fine quality of copra, as it is only from the finest qualities that the best edible fats derived from this source can be pro- duced, Small crops are anticipated for 1909. During 1908 the average price for Java copra was £1 148 4d per bale of 220 Ib LL GC. BHa- press, May 14, JAVA GCOPRA is fast losing its good name in the market owing to careless methods of preparation. The Chamber of Commerce at Samarang has urged the Java Government to take action by ins- pecting all copra prepared for foreign markets, so that only the certified article shall be ex- ported. The Chamber has drafted a bill for the purpose which is now under the consideration of the Government. Java copra hasa high re- putation from being mostly dried in the sun, 599 and not artificially. But now fire-drying has become so common that the time is approach- ing when Java copra can no longer be marketed as fair, merchantable sun-dried. There is danger of its being classitied low as fair merchantable, or fair merchantable, kiln-dried. Further dis- favour has fallen upon the article by preparing it from unripe coconuts.—Straits Times, May 28, SOUTH CAROLINA TEA. Mr Consul Donnelly, reporting on the Con- sular district of Savannah, says:—...Tea, which was for a long time considered one of the pro- ducts peculiar to the Far Kast, is now accepted as fully naturalised in the south, and it is stated by those interested in the matter that South Carolina tea will soon be as well known to drinkers of this beverage as is the best leaf of Formosa or Japan. The South Carolina teas that seem to thrive best are of the better varie- ties, and teas grown in this State can now be bought at one dol (4s 2d) per lb, which are said to compare favourably with good grades of im- ported China, Japan or Formosa teas in flavour, quality and price. Good foreign teas cost in this country as much as 1 dol or more per lb. South Carolina tea could not compete in price with much of the cheaper importations. The majority of the people here are not tea drinkers —cotiee being the favourite beverage, but there seems to be a change taking place in this re- spect.—Financier, May 1. A BiG CROP OF COCONUTS. A paragraph in an F, M. 8, Contemporary states that there is on Klanang Estate a coconut tree which had upon it a short time ago 360 nuts. Though it has not quite so many at present, the tree is still a very remarkable sight. Not only is it literally loaded with large nuts, but a number of small ones are to be seen in the earlier stages of development. Curiously enough the tree is by no means a large one, and is only about eleven years old. PRUNING ORANGE TREES, ‘Orange Tree” asks :—Do orange trees require pruning? Ifso, state to what extent. The answer to this question might be ‘‘Yes” or ‘“No,” but to be more definite I would say that anyone who requires to ask the question will be well advised to let his trees alone, for he is more likely to do harm by pruning as the word in generally understood than by allowing nature tu take her course. You give me no idea as to whether you are referring to old or young trees, but it may be worth whiie indicating in a general way the principles which should guide the owner of an orange tree in his treatment. We will suppose that you are referring to young trees just planted. Contrary to the generally accepted ideas [ believe that it is as important to cut orange trees hard back at the time of plan- ting as it fs to so treat apples, pears, and other deciduous fruit trees, and for the sam) reason, te oe ’ if 600 hen the tree is taken from the nursery its roots ae mutilated and probably at least four-fifths of them and possibly much more have been cutaway by the spade. lt is, therefore, wise to remove a corresponding portion of the top, and personally when planting a young tree 1 would invariably eut it back to short spurs of from 3 to 8 inches long and remove the majority of the small twigs. When a tree so treated, or indeed if it has not been so treated, starts to grow, it will be found to almost imvariably put out a great number of buds. If all these are left, they result in small spindly growths, and the proper plan is to rub off all but those that are required when they are from half-an-inch to two inches long. If my advice is followed and the young tree is cut hard back, you will only require to allow from 3 to_6 shoots to grow. | If one cr two of these begin to make eXCesB1VE growth ahead of the others, 1t 1s advisable to nip vut the tender tops to allow the develop- meut of those that are less strong. Any shoots which put out from the trunk of the tree below where it branches should be rubbed off as soon as they appear. In the second year’s growth you will generally find that from the ends of the previous years shoots from three to slx buds start, and the proper treatment is to remove all but one or two. If this plan be followed no pruning as generally understood will be required for many years. In the case of older trees all the pruning re- quired is to remove any weak and spindly wood, any shoots that seem to be diseased or dying, anc to generally thin out the tree just sufficiently to allow light and air to pass right through it. If you will take notice of old trees which have not been thinned in this way you will find that, although they may be perfectly healthy, they are so dense that all the inner twigs are spindly and of poor colour and practically all the fruit is borne on the outside of the tree exposed to the light. If a tree is kept open in the way I have indicated this will not be the case, and the fruit will be distributed throughout the tree. This results ina bigger maximum crop and better development of the fruit. —Western Mail, May 22. TEA IN THE ANDAMANS. ay not be generally known that tea is as as a small scale at the Andamans, where 160 acres were placed under this crop in 1907-08, and the outturn of the finished product amounted to 41,605 lb, against 60,290 lb. in the preced- ing year, which was a record, or nearly 376 1b, per acre. The decrease is attributed to the un- favourable weather. Itis, however, not quite clear why this tea gardenis maintained, because it was worked at a loss of R17,808. If the tea garden were self-supporting, even though there were no profits, there might be some extenuation for its upkeep. The greater portion of the out- turn was supplied to the Supply and Transport Department, and 3,423 Jb. was sold locally, to the former at 0-5-3 and to the latter at 0-4-0 per Ib. There is also a coffee garden in the Settle- ment which has been leased to a contractor for R750 per annum.—Madras Times, pee 31. NEL 9) The Supplement to the Tropical Agriculturist A SUGAR-CANE FACTORY, In SoutH Arcot, It is stated that a Company will shortly be floated with a capital of R1,35,000, for for- ming a sugar-cane plantation of about 450 acres in extent at Valavanur, in Villipuram Taluq, South Arcot, the intention being to work it on up-to-date scientific methods, under the management of a specialist, as is done in Java, and to erect a small factory with the necessary plant for dealing with the produce of 100 acres and converting it into refined sugar. For the plantation purposes an outlay of about R60,000, inclusive of the cost of the land, irrigation appliances, etc., is contemplated, with an annual expenditure for upkeep of about R15,000 for 100 acres cultivated. The cost of building a Sugar Factory, and provi- ding it with the necessary machinery is esti- mated at R60,000. The average cost of gro- wing cane locally works out at R90 per acre, and the receipts average, on the basis of the price of R2) per candy of jaggery, R250 an acre. On the Government Farm, at Palur, however, and on Messrs. Parry & Co.’s Farm near their Nellikuppam Factory, the annual expense is said to be about R120, and the yield about R450, an acre. The ryots, who have been able to put up the bullock-driven crushers supplied by some Madras firms, are said to be able to realise, after meeting the expenses of jaggery-making, a net profit of R25 per candy of jaggery, Taking, however, the lower yield of R250 an ~ acre, the receipts from 100 acres would amount to R25,000, while in the remaining area belong- ing to the Company local crops can be raised to the ordinary yields obtained. The cane from 100 acres (6,000 cart-loads of 3,000 tons, worth R25,000, as abve shown) is calculated as a re- sult of actual experience to yield 200 tons of sugar wortha 217 a ton, z.e., R43,400, and 100 tons of molasses worth R54 a ton, 7.e., R5,400. The expenses of manufacture amount to R8,200 at R41 a ton of sugar, and allowances for depreciation of machinery, building, etc., at 10 per cent. of their value, would come to R6,000. There would be then from sugar manufacture alone a profit of R9,600. This, with the R25,000, the value of the cane raised on the lands, brings up the total income from the plantation and the factory to R384,60C, which, on the capital of R1,35,000, means a return of 25 percent. That there is a very wide field for sugar in- dustry in this country is admitted, asthe imports of sugar from Java, Germany, Austria, etc., are steadily increasing ; and with a view to deve- loping the industry, the Government, at the Industrial Conference held at Ootacamund last year, expressed their willingness to give all possible encouragement to promoters of the sugar industry. The enterprise being shown in this connection by certain Hindu gentle- men of Valavanur, which has hitherto been famous rather as a ground-nut growing and trading centre, is very much to be commended; and everyone will |wish the promoters such a measure of success thatit will lead to many other similar undertakings being established. —M Mail, June 4. No. XL. Printed for the Ceylon Agricultural Society THE RICE-BUG OR PADDY FLY. ‘He rice-bug is the same insect that in Ceylon is known as the paddy fly, and causes great damaye to local crops. Indeed, the necessity for rigid observance of seasons in paddy cultivation is chiefly due to the attack of fly which an out-of-season crop is invariably subjected to. An Indian report (by Mr. H. Maxwell-Lefroy, the Imperial Entomologist) contains a very full account of the pest, its distribution, habits, and life history, as well as the method of combating it ; and the information given below is mainly abstracted from that report. The scientific name of the rice-bug is Leptocorisa varicornis, and the genus is believed to include three species ; but the points of distinction are very slight, and probably do not imply any difference in life history. The bug is commonly found in long grass and thick vegetation, being present here singly. It is only at special times and on special crops. such as paddy, that it occurs gregariously. The morning and evening are its most active periods, and during the hot part of the day it goes deep into shelter. As all who are familiar with the insect know, it is coloured green, and associated with an objectionable odour, being hence sometimes called the “Green bug.”’ Its normal food is the sap of flowering shoots of grasses. When infesting paddy, it feeds on the tender developing grain. which is full of milky sap. The dark brown eggs are laid on leaves in clusters or rows, and number from twenty-four to thirty. They are protected by a gummy substance, which helps to attach them to leaves and prevents their being washed away byrain. The eggs take from six to eight days to hatch out. Between hatching and maturity the nymph passes through five stages, occupying, say, about eighteen days, during which time the wings are gradually developed. It is not exactly known how long the imago, or fully developed insect, lives, but insects have been kept alive in captivation for three months. The following is an actual record : Eggs hatched on September ~, adults reared on 18th, and lived until November 2. Of enemies to the rice-bug, there are two known: Cicindela seepuncta, Lin, which is abundant in rice fields in India from August to October. This is a flying insect and destroys the rice-bug in numbers. Another is an egg parasite, which has not been described as yet. Ordinarily, the bug occupies « life cyele of from tour to five weeks in warm weather, breeds freely with the rains, and feeds on rice, dry grain, and grass. There are apparently five broods, depending, however, on local conditions, food supply, &c. With cool weather the insect leaves the open field and goes into the denser shelter of uncultivated land. There is nothing to show that it breeds again till the following rains. We now come to the most practical part of the circular, namely, that referring to treatment. (1) There is the treatment resting upon superstition, and consisting of “‘ mantras”: or charms. This may be put down as utterly useless. (2) Smoking by burning aromatic herbs and resinous substances to windward. This is only a temporary remedy and, though useful in saving individual fields, merely shifts the enemy. (3) Ropes saturated with resin or kerosine or fish oil are drawn over the fields so as to brush against the ears of paddy. This is rather more effectual than the last. (4) A paddy winnow smeared over with some glutinous substance like birdlime (e.g., jak milk) is tied to a long pole and passed over the heads of paddy, so that the insects are caught in large numbers on the sticky substance on the winnow. The process has to be repeated over and over again. It is tedious, but simple and effective. (5) An elongated cloth bag is run across the field sweeping in the bugs as they rise. The bag is either soaked in crude oil emulsion (1 pint emulsion to 2 gallons water) or the inside smeared. with something 9(4)09 (2) sticky. A bag, 8 ft. wide and 3 ft. high, is a convenient size, the sides kept open by bamboos 3 ft. long, which serve as handles for grasping it. The width is about as much as two men can run with. A smaller bag may be suspended by ropes (see fig.). Mr. Lefroy strongly recommends such an appliance, and doubts whether any better will be found. The work is best done by co-operation and the treatment of large areas together, as bags cost something to make. (6) It has been found that a mixture of bran and jaggery serves as a bait for the bugs, and that they could be captured and destroyed easily when they can be got to congregate together by this means. An important point to be remembered is that the best work can be done by attacking the rice-bug when in the field and before the rice comes into ear, and not by waiting till it has invaded the fields. The cultivator should therefore look out for the insect and its eggs and destroy them. For, if let alone, each pair will in a month or so produce about 24 bugs and in two months 288, and so on. The enemies of the bug should also be recognized, and must never be destroyed. [To make kerosine emulsion: Boil 4 lb. sliced bar soap in 1 gallon water till dissolved. Take off fire and add 2 gallons kerosine, agitating mixture till a milky emulsion is formed. Dilute to required strength (usually with 6 to 10 parts water) for use. Where crude oil is used, dilute each gallon with 66 gallons water, or 4 a pint to one kerosine tin water. | Bag ready for use. C. DRIEBERG. No. LXI. Printed for the Ceylon Agricultural Society. NITROGEN-GATHERING CROPS. Ir is needless to discuss the value of Papilionaceous crops in agriculture. The manner in which these plants import atmospheric jnitrogen into the soil with the aid of the bacteria in the nodules on their roots is now pretty well known, since it has been explained over and over again in the Society’s publications and by its travelling instructors. The question is: often asked, what ‘leguminous ‘crop ‘should: be grown with the objectZof its being wholly. or’ partially returned to the land. The tendency in most matters is to look for something new, and the newer the better! As a’general rule, however, these new plants are unsuitable to local conditions, unless, of course, they came from countries with almost identical natural conditions. Wild species of Crotalaria have been highly recommended and utilized with marked benefit both in up-country and low-country estates. The difficulty, however, in inducing the native cultivator to grow such a crop as Crotalaria striata is that he does not see sufficient virtue in a plant that does not give him some tangible return. For this reason, it is politic to reeommend to him—for the present at least—a crop which yields him some useful produce. The American cow-pea (Vigna catiang) is a plant that has come back to}Ceylon with a new name, since it is no more than a variety of the familiar mé beans largely cultivated, particularly about Colombo. The legumes are wholesome and palatable when taken early, and command a ready sale as “ curry beans.” There are other crops which similarly yield marketable produce, such as dhall (Cajanus indicus), san-hemp (Crotalaria juncea), dhaincha (Sesbania aculeata). Whether cow-pea or one of these three should be selected is for the cultivator himself to decide after carefully considering the “ pros and cons ”’ of the case. All are excellent in rotation, or as “‘inter-crops”’ in permanent plantations. The dwarfish forms of cow-pea or mé are perhaps more suitable from the point of convenience, especially when grown as inter-crops. Dhall (Sin. rata-tora, Tamil thavarai), which yields one of the staple foods in India, is a shrubby plant, which sometimes grows up to a height of 15 or,20 ft., and will suit cases where shade is also a desideratum. These two plants (cow-pea and dhall) are therefore of economical value as food crops. {In this connection may also be mentioned ground-nuts (Arachis hypogea), but the great difficulty of protecting and harvesting the crop in Ceylon has made it unpopular among cultivators. ] Crotalaria juncea and Sesbania aculeata, on the other hand, are fibre plants, and will suit localities where there is use for fibre. The first is already under cultivation in, the Chilaw District, and in parts of the Northern, Province, the fibre, which is extracted by the,simple process of retting or steeping in water, being in requisition for fishing nets, &c. Dhaincha is practically unknown in the Island, but is closely 9(5)09 e ( 2 ) related to our katurumurunga (S. grandiflora) so commonly grown in vegetable gardens, and of which both the flowers and leaves are used as food. The reasons why it is brought forward in this connection may be stated as follows :— (a) It is referred to in the “‘ Handbook of Indian Agriculture” as ‘‘ richer in nodules than perhaps any other plant.” (6) (c) It is suitable for low wet land, and will therefore do for most paddy fields. (d) It was recommended to Indian tea planters by Dr. Mann, and gave excellent results. (e) ” and by Roxburgh to be “ more durable than san-hemp for use in water.” Dhaincha is a plant which, under favourable conditions, may grow up to about 14 ft., though it is generally of smaller growth. When broadcasted fairly thick—say, at the rate of 30 lb. of seed per acre— it keeps down weeds, and should be ready for cutting for fibre in 4 or 44 months, so that if sown in April, the ground, fertilized by the crop-residue, will be available for other cultivation in September. The fibre was at one time valued at from £30 to £35 per ton, but this valuation will have to be revised on a present- day basis. The seed has proved useful as a famine food in India. Without any desire to exaggerate the properties of dhaincha, the statement may be given for what it is worth that the lack of organic matter and cohesion of soil particles in land is easily remedied by growing one or two crops of dhaincha. The plant may be seen growing at the Government Stock Garden. Orders for the seed can be booked through the Secretary. C. DRIEBERG, Secretary, Ceylon Agricultural Society. Colombo, February 20, 1909.
