(1487) PREFACE Although the products of the plant world are of enormous commercial importance and enter largely into the every-day life of all of us, nevertheless it has hitherto been impossible to obtain an inexpensive illustrated book, written in English, affording a general summary of information concerning the useful plants of the world and their commercial utilisation. Works dealing with special groups are available, and innumerable papers on plant products are to be found in the publications of our economic and scientific departments at home and in the Colonies. This literature, however, is not readily available to a very large number of enquirers who desire a comparatively brief account of perhaps several important products. Illustrations of many economic plants, and of the methods employed in their cultivation and in the preparation of their produce, are even more inaccessible. The World's Commercial Products presents this information in English for the first time, accompanied by a wealth of illustrations many of which are entirely new. Every effort has been made to keep the book free from technicalities, and the plants are, as far as possible, referred to by their common names, although the scientific names are usually given as well, since they are often indispensable in determining exactly the plants referred to. The coloured plates will often be of assistance in depicting scenes to which full justice cannot be done in " black and white," but all the illustrations are from photographs, and can be depended upon as portraying faithfully the scenes they represent. Maps have been added showing the distribution of the principal cultivated plants, and many useful lessons may be drawn from them. One of the authors has spent some six years in the tropics, in Ceylon, the West Indies, and West Africa, engaged in economic botanical work, and much of the matter is described from first-hand knowledge. In addition, the copious literature referred to below has been freely drawn upon, and special acknowledgments are due to the publications of the Royal Botanic Gardens, Kew, the Bulletin of the Imperial Institute, the publications of the Imperial Department of Agriculture for the West Indies, the Agricultural Journal of the Royal Botanic Garden, Ceylon, Sir George Watt's " Dictionary of the Economic Products of India," Spon's " Encyclopaedia of Arts and Manufactures," Lewkowitsch's " Oils and Fats,-' Greenish's " Materia Medica," Wright's " Para Rubber," the International Sugar Journal, Noel Deer's " Sugar Cane," Willis's J Dictionary of the Flowering Plants and Ferns," JG6979 PREFACE Engler and Prantl's " Die Natiirlichen Pflanzenfamilien," and last, but far from least, the publications of the United States of America Department of Agriculture. Great advantage has accrued from the co-operation of other workers. Dr. T. A. Henry, F.C.S., has contributed the sections on Gums, Resins, Dyes, Tans, and Essential Oils, Mr. C. E. Jones, B.Sc, F.L.S., the section on Oils and Fats, and Mr. E. H. Wilson the sections on Fruits and Vegetables. The Timber article has had the benefit of Mr. J. H. Badcock's extensive practical knowledge of this subject. Limitations of space have prevented every plant product being included, but care has been taken to deal with the more important, and it is hoped that the specialist and the general reader alike will find the World's Commercial Products a useful possession.

Imagine for a moment what the world would be, if it was deprived of plant life. Wheat, rice, millets, oats, maize, and the other cereals, on one or other of which every individual of both the most primitive and the most civilized nations depends for his sustenance, would disappear, together with potatoes, yams, cassava or manioc, and all the important starch-producing plants. There would be no fruits or vegetables ; tea, coffee, cocoa, and sugar would vanish ; tobacco and many of the chief drugs would cease to be obtainable. Most modern sports would be impracticable because there would be no india-rubber for balls and tyres, no wood for bats, golf sticks, and racquets, and leather could no longer be tanned. Cotton and linen would go, and wool, hair, and silk would be the only fibres for the manufacture of cloths and other textiles. There would be no wines or spirits, in fact, life as we know it at present would come to a standstill. Supposing, however, that man could exist in a world containing no plants, to what extent could he manufacture, with all the assistance which modern science affords him, the substances necessary for his life ? In spite of the enormous strides which science, and particularly chemical science, has made, man could not support himself . It is true that one section of the commercial world has recently been profoundly affected by the artificial manufacture of indigo. Another section is seriously considering the situation created by chemists having discovered how to make vanillin, the essential principle of the vanilla "bean." The development of the coal-tar industry has practically extinguished certain planting industries. From time to time fears are expressed that the artificial manufacture of sugar, already possible, or that the preparation of chemical rubber may become commercially practicable. In spite, however, of these developments the fact remains that man is unable to repeat the processes by which the wheat plant manufactures starch from water and the atmosphere. He cannot from similar elementary substances make cotton, wood, the active principles of tea, coffee, cocoa, or tobacco, for all of which he is dependent on plant life. There is no need to elaborate the matter ; enough has been said kto prove the absolute importance and necessity to man of the vegetable products of the world. There is a tendency, however, for man as he becomes more civilised to fail to recognise i— CP. The World's Commercial Products the degree to which he is dependent on the herbs of the field for his support. The dweller in cities is accustomed to find everything pro- vided for him in a finished condition, and he accepts it without realising whence it came or how it was procured. This is easily seen in the case of a child spending his early years in a town. It comes to him as a revelation that his daily bread has any connection with the corn he has perhaps seen in a field during a holiday, that sugar and his favourite sweetstuffs are derived from the sugar cane grown in the tropics, or from the more familiar beet-root, that his rubber ball is the produce of a forest tree, and that his clothes, at any rate in part, have also been gathered in the field. To the country child things are different. He lives in touch with Nature, and the seasons for sowing and harvesting are important events in his daily life. Still more so is this the case with primitive people. The native races of the East and the West Indies, Africa, and elsewhere are directly dependent on the soil for their livelihood. A bad season makes itself felt at once by diminishing the available food, whilst a plenteous harvest means a full table. We have only to go back a comparatively few years to find the same state of affairs the universal rule in this country, and in many parts it is still so at the present day. Primitive man lived directly on the wild plants he found in his native country, and from these also he made his few clothes, his house, his weapons, his canoes, and the other necessaries of his simple life, supplementing the plant products from the animal and mineral worlds. At a very early stage man took the important step of growing for himself the plants he most needed, and agriculture, or the tilling of the soil, is perhaps the most ancient occupation of mankind. The natives on the West Coast of Africa afford an example of the practice of simple agriculture. A tribe settles in some locality which attracts it for one reason or another, such as accessibility of water, fertile soil, abundance of oil palms, or other important wild plants, and security from enemies. An area is cleared by cutting down and burning everything, except a few trees so large as to defy man's efforts, and others which it is desired to retain. On the land so cleared crops are raised. Indian corn, Guinea corn, cassava, yams, sweet potatoes, bananas, ground or monkey nuts, various peas and beans, and perhaps some cotton are planted, and on these, supplemented by the products of wild plants and animals from the bush, the tribe lives in comfort. Agriculture, as we understand the term, is not practised, and it is found that the soil is soon exhausted. This is of no serious consequence where there is far more land available than is required, and even to move the village or town to a new place is a task entailing no great labour, although in most cases it is sufficient to abandon one " farm " and to clear and cultivate another. HARVESTING PADDY IN CEYLON Introduction ui In sparsely inhabited countries millions of people live in this manner at the present day. With increasing population these methods become impossible, and in China we find -the soil cultivated to its fullest extent, and all possible means adopted to increase the output from a given area. In most countries it was soon found that all districts were not equally adapted to the cultivation of every crop, and a simple system of exchange arose by which one group bartered perhaps their surplus cotton for rice or some other commodity to the cultivation of which their own locality was not suited. In closely adjacent areas this exchange would be carried out directly by the producers. As man became more enterprising and the means of communication developed, people travelled further afield, and now in Africa men journey hundreds of miles with a portion of their crop to exchange it for some valued product brought to the rendezvous from perhaps an equal distance by another group of producers. The business of the exchange of goods had reached a high degree of development before the Christian Era. The Carthaginians By permissio BIG TREES IV The World's Commercial Products traded throughout the Mediterranean and also with Britain, the Baltic, and the Azores ; by means of caravans they penetrated Africa, reaching as far as Egypt to the East, Morocco to the West, and across the Sahara to the River Niger. The Romans, the Greeks, the Venetians were all trading peoples, and by their enterprise the wealth of India became known and accessible. Another result of this intercourse between nations was that the useful plants of the world became widely distributed. The cultivation of the most important of those of the Old World, those which are absolutely necessary to man, dates from very remote ages. If we had been preparing, some three or four thousand years ago, a book similar to the present on the commercially useful plants we should have had to include wheat, barley, rice, millets of various kinds, tea, flax, hemp, the vine, the olive, the date, bananas, various legumes, and other vegetables. It is true we should not have heard of the potato or the sweet potato, tobacco, cocoa, or Indian corn (maize), but these have been cultivated for almost as long by the American races, and were waiting for the discoveries of Columbus and his successors for their introduction into the Old World. This early discovery and the utilisation by man of the most valuable plants is one of the most extraordinary facts in the history of agriculture. As De Candolle well puts it in his most interesting book on The Origin of Cultivated Plants, " Men have not discovered and cultivated during the last two thousand years a single species which can rival maize, rice, the sweet potato, the potato, the bread fruit, the date, cereals, millets, sorghams, the banana, soy. These date from three, four, or five thousand years, perhaps even in some cases six thousand years." The useful plants grown in Graeco-Roman times were not added to in any degree prior to the discovery of America. The finding of America brought in a number of plants new to the Old World, and of very high value, such as the potato, maize, sweet potato, tobacco, and cocoa. Within a comparatively short time these plants also found their way into other countries. The potato reached Europe at about the end of the sixteenth century, and as indicating the interest which attached to this novelty we find that in a book, Gerard's Herbal, published in 1597, Gerard selected, in presenting his own portrait, to hold in his hand a flowering branch of the potato plant, which he had cultivated in his garden. The maize plant rapidly reached almost all tropical countries, cocoa was taken to Ceylon and elsewhere, and in this way the greatest additions to the number of really important cultivated plants of the Old World since very early times was brought about. Another important American plant, cinchona, the source of quinine, was introduced to cultivation largely through the agency of a man still living — Sir Clements Markham, K.C.B., F.R.S. It helped Ceylon over the coffee crisis, and it is at the present time the source of an important industry in Java. As man's life became more complex and his wants increased he found it necessary to form plantations of other species, such as fibre and rubber-yielding plants. Para rubber is the most important of the new industries in the East, where in Ceylon and the Malay peninsula its cultivation is attracting much labour and capital. This valuable plant is a native of Brazil, and formerly the whole of the rubber it yielded was collected from wild trees scattered A CHINAMAN THRESHING MILLET THE VINTAGE IN PORTUGAL VI The World's Commercial Products through the dense forests in the Amazon valley. As recently as 1886, by the enterprise of the Indian Government and with the assistance of the Royal Botanic Gardens, Kew, it was successfully introduced into Ceylon, and promises to become an important source of wealth. Cultivation of this and other rubber plants is also being undertaken in parts of the tropics, and the rubber trees are amongst the latest addition to the list of cultivated plants, an addition which has taken place in our own generation. It is probably safe to say that by this time most of the useful plants of the world are known. We are not likely to discover anywhere a plant which will rival wheat, rice, cotton, tea, coffee, cocoa, the vine, or the chief sugar producing plants for their respective products. We may add considerably to the number of cultivated plants, when, as has happened with rubber trees, it becomes advantageous or desirable to cultivate them instead of relying on the wild product. Much work, too, remains to be done in improving the plants already to hand. This is one of the most important divisions of the work of . the botanic gardens and experiment stations throughout the world, and in discussing sugar attention is directed to the good results attained on these lines with the sugar cane in the West Indies, Java, etc., and with the sugar beet in Europe. Similar work on other plants is being conducted elsewhere, and is referred to in its appropriate place. At the present time we have throughout the British Empire a well-developed system for securing the introduction of useful plants into any colony, and there are no serious difficulties in introducing any plant into any place where it is likely to thrive and its produce to obtain a profitable market. The latter depends to a great- extent on facilities for transport. That these are in a high state of efficiency is easily recognised when we think of the origin of the ordinary items of our every-day fare. The flour of which our bread is made comes from America, India, Argentine, Australia, Russia, and elsewhere, tea from India, Ceylon, and China, coffee from Brazil and Central America, cocoa from Ecuador, the West Indies, West Africa, etc., sugar from the East and West Indies or Europe according as we use cane or beet. These are all products which are easily carried, and are not damaged even if delayed in the voyage. During recent years, however, other items have been added to the import list, and the Channel Islands and the South of France provide us regularly with large quantities of potatoes, vegetables, and fruit. More striking, however, are the developments resulting from scientific discoveries which have rendered possible rapid means of transport and cold storage. Our apples, a few years ago essentially a home crop, come to a very considerable extent from Canada, the United States, and Tasmania. In the latter instance they have to withstand a voyage of six weeks' duration, starting in the temperate region, passing through the tropics, and terminating in the temperate clime of another hemisphere. Yet these apples, unpacked, look as good as when they were picked. Bananas, which are increasing in popularity, come from such widely separa- ted places as the Canary Islands, Jamaica, Costa Rica, and Barbados. Delicate fruits, such as grapes, reach us in safety, and peaches and plums from the Cape of Good Hope can be seen in increasing numbers in British markets. Fruits are so easily Martinique, the cultivation of cocoa damaged by any defects in the means of Introduction vu FILLING A MAIZE RICK transport that they afford a reliable means of testing modern methods, and anyone who wishes a demonstration of the excellence of these methods ought to visit one of the exhibitions of Colonial-grown fruit held by the Royal Horticultural Society. Enough has been said to indicate that there is great interest attaching to the ordinary articles which are so familiar to us in every-day life. Some products, such as flour, sugar, and tea, are obtained only from cultivated plants, often grown now in countries far removed from those in which they originally occurred in the wild state. The raw material passes through successive processes before it leaves the land of its production, and after it reaches the country where it is used undergoes other transformations. Other useful substances, on the other hand, are obtained from wild plants, and are collected by primitive and sometimes interesting races, prepared by crude methods, sold at the outposts of some great trading firm beyond perhaps the confines of civilisation, and finally shipped to this country. It is obvious that an account of the cultivation, collection, preparation, and uses of the products of every-day consumption cannot fail to be of great interest. Incidentally we learn much not only about the objects themselves, which in itself endows them with much greater interest, but also about the lands of their production and the conditions of life which prevail there. In this book an attempt has been made to give a general account, on the lines indicated above, of the principal plant products which occur in commerce. The work is necessarily incomplete, because it is impossible in a volume of this size to describe in a manner which Vlll The World's Commercial Products would have any interest all vegetable commercial products. To do this the work would have to run to. many, volumes. Thus, some years ago, the Government of India produced, under the direction of Sir George Watt; a Dictionary of the Economic Products of India. Now, India, although a large country, is small in comparison with the whole world, and yet this work on Indian products alone* extends to a monumental series of eight large-paged volumes. A selection has, therefore, had to -fee- made, and, for purposes of convenience, the products have been arranged in natural gr.oups. This method has allowed of general information being given on properties common to all the members of the group, of devoting most space to the more import- ant products, and of mentioning the others in their appropriate places without that detachment often. entailed-in a book in which each product is treated of separately without reference to its place in a great group. The. results of personal observations in many parts of the world, contributions from experts engaged daily in handling the products under consideration, and the consultation of standard authorities have been blended to make the volume as far as practicable a concise and simple account of '.the chief plant products of the world. The book cannot hope to be faultless and the magnitude and complexity of the subject treated must be our excuse for any shortcomings. W. G. F. S. E. C. THE ENGINE ROOM OF A SUGAR FACTORY IN JAVA STRIPPING WHEAT IN wrt The Worlds Commercial Products WHEAT : Amongst the World's Commercial Products the first place, if not in actual monetary value at any rate in importance to man, must be given to the foodstuffs on which his very existence depends. In the times before means of transport were perfected, each nation was self- supporting. Indeed, each tribe or even each family collected wild plants, or raised the crops for its own sustenance. This state of affairs still exists amongst the more primitive races. In West Africa, for example, there are near each village the "farms," often worked by all the people in common, where are grown the supplies of Indian corn, millet, cassava or manioc, yams and other edible roots, on which, in addition to the wild products collected in the " bush," the members of the tribe exist. After the harvest' the crop is carefully stored either in the field, in special granaries, or in the individual houses to last over the period before the next crop is ripe. No greater injury can be inflicted on a village than to-destroy these stores, especially if, in addition, the supply of seed for the next season's sowing is taken away. The natives in Central America, etc., subsist largely on manioc, and a jar of farine, or the meal of this plant, is commonly to be found in each hut. A similar state of affairs was formerly the rule in such countries as Great Britain, and although the advance of civilisation has revolutionised this simple mode of life for the industrial and other sections of the community, we have only to consider the conditions of life of the peasantry of the west of Scotland, parts of Ireland, and elsewhere to realise that even now there are large numbers of families in the United Kingdom practically dependent on their own efforts in tilling the soil for their support. 2— C.P. The World's Commercial Products This, however, is not the case for the majority of the inhabitants of modern civilised countries, who no longer live by direct tilling of the land. To supply their needs foodstuffs must be grown, frequently either in part or wholly in other countries. Some idea of the enormous development of the trade in foodstuffs may be gathered from the fact that the annual value of wheat alone imported into the United Kingdom is about £35,000,000 sterling. The most important amongst these foodstuffs are undoubtedly the cereals, namely, wheat, barley, oats, rye, rice, Indian corn or maize, millets, sorghum or dhurra, and others less widely used. More than one half the whole population of the world subsists to a great extent on rice, and the vital importance of wheat needs no demonstration. The cereals are members of the great family of the grasses which have been cultivated by man from time immemorial. Originally, no doubt, they were wild plants which attracted attention owing to the comparatively large quantities of foodstuffs they yielded, the ease with which they could be collected, and their edible qualities. Now, in the majority of cases, the original wild forms are no longer known, and as is common with plants cultivated in many lands and during long periods, innumerable species and varieties have been evolved as the result of conscious and unconscious selection by man of the forms which appeared desirable for one or other of their qualities. Their very name — cereals or cerealia — indicates the great value attached to them in early historic times. They are so named after the goddess Ceres, as the Romans called her — Demeter of the Greeks — the pat- roness of agriculture and all the fruits of the earth. In the temperate regions of the world wheat is the principal cereal grown, and there are many different varieties suited to varying conditions. As we go farther north, barley, oats, and rye increase in importance, and although they are grown for special purposes along with wheat, it is important to note that they will thrive in countries and under conditions not suited to wheat. Starting again from the temperate zones and travelling north or south, as the case may be, we enter the warmer countries where wheat cultivation is often associated with that of rice, maize, sorghum, etc. In the tropics, however, wheat will not thrive at low elevations, but rice, maize, sorghum, and various millets form the great cereal crops, their relative importance varying in different countries. Sometimes the use of the word " cereal " is extended to include buckwheat and other starch-yielding plants, but these are not true cereals. There are also the important starch- yielding plants such as the potato, yam, sweet potato (a kind of convolvulus), manioc or cassava, etc. These all form underground tubers, and are regarded as vegetables, in which section of this book they are discussed. Still another group of starch plants exists yielding arrowroot of various kinds, sago, etc. These are treated in the section on starches and meals. We will now turn to the consideration of the cereals and deal first with those of temperate countries, and afterwards with those grown in the warmer regions of the world. Of the first group by far the most important is wheat. Throughout the temperate regions of the world are found a considerable number of grasses, either wild or cultivated, which are sufficiently alike for botanists to group them together into a genus and to call them all by the old classical name for wheat, namely, Triticum. Three of these wild forms occur in Great Britain, one of THE MOTOR IN AGRICULTURE SJ J [ X ^ s2° I r f D The World's Commercial Products A POOR YIELD OWING TO BAD CONDITIONS WHEAT GROWN UNDER GOOD CONDITIONS the best known being " couch grass " or " twitch," which is a very troublesome weed in cultivated land. But it has its uses, inasmuch as its long, creeping, underground stems give it the power of binding sand so that it can be planted to arrest the progress of sand dunes, to hold together embankments, etc. These wild " wheat grasses " are, however, of no value as food plants, yielding but little grain. On the other hand, the cultivated species which, for the time, may be collectively spoken of as wheat, are of the greatest importance, yielding the most valuable cereal in the world. Wheats have been cultivated by man from time immemorial, and nothing is now known of the original wild forms from which they are descended. In old legends and ancient manuscripts wheat is spoken of as familiarly as at the present day. Nor do we know with any certainty in which country it was first found ; but it seems probable that Central Asia was the original home of the wild forms from which the cultivated species have sprung. Although we have used the name " wheat " above as including all the cultivated varieties of the genus Triticum, this is not quite correct, and before proceeding farther it will be well to give a few notes concerning the various species. They fall into three chief groups : — 1. Small spelt, or one-grained spelt (Triticum monococcum). 2. Wheat, including spelt and rice spelt (T. sativum). 3. Polish wheat (T. Polonicum). (1) Small spelt or one-grained spelt is usually characterised by each of the little branchlets of which the ear is composed, containing only one grain, whereas in the other wheats they contain two or more grains. This plant can live in very poor soils, and in stony places not suited to ordinary wheat. As might be expected, it does not grow into such a large plant, the straw being usually not more than from eighteen inches to two feet in height, and the yield of corn is comparatively small. Spain is the chief country in which it is grown, but it is sometimes cultivated in France, Germany, and Switzerland, principally in mountainous Wheat 5 WHEAT GROWN IN SOIL MANURED WITH PHOSPHATES districts. Although it is now little used, its cultiva- tion is of great antiquity, as shown by the finding of grains of this plant in the famous lake dwellings of the Stone Age in Switzerland and Hungary. (2) Wheal and Spelts. The spelts are amongst the grains which have been cultivated from the most ancient times, and they were the chief cereal of Egypt and Greece. They were cultivated by the Romans and distributed throughout the Roman Empire. The plant has decreased in importance, but it is still of great value in the south of Spain, as it is very hardy and can be depended upon to give an average crop even on poor soils. Some of the varieties of spelt have ears like those of ordinary wheat, whilst others are bearded like barley. Another variety is the two-grained spelt, fre- quently known by its German name of emmer. Starch wheat or rice wheat are other popular names. The ears are usually bearded. Long known in cultivation, it has also declined in favour, and is now principally grown in southern Germany, Switzerland, Spain, Servia, Italy, etc., as a summer grain. There are different races differing in the colour of the grain, which may be white, red, or black. Attention has recently been devoted to this grain as, like the macaroni wheats, it thrives in the dry regions of North America where irrigation is impracticable. This subject is discussed more fully below in relation to so-called " dry farming." The third group includes the true wheats, and these may be sub-divided into four classes. (a) Common Wheats. This class includes all the most valuable kinds for making bread. Some have ordinary ears, others are bearded ; the colour and other characteristics of the grain vary, and innumerable varieties, each with its own name, are distinguished. (b) Dwarf or Hedgehog Wheats. These are low-growing wheats with very short but thick and strong straw. They are grown on poor soils, principally in the Austrian Alps, Wurtemburg, Alsace, Turkestan, Switzerland, and Chili. (c) English Wheat or River Wheat. Although called English wheat this kind is but rarely cultivated in England, being chiefly found in the countries bordering on the Mediterranean. The flour derived from it is not well suited to making bread, and must be mixed with flour from the kind next mentioned. (d) Hard or Flint Wheat. The ears of this group of wheats are furnished with long, bristly awns. The grain is hard and contains a large amount of the substance known as gluten, which will be referred to later. Flint wheats are most important in Spain and northern Africa. They are of special interest as yielding the best flour for the preparation of macaroni, Italian pastes, etc. (3) Polish Wheat. This, the last member of the wheat group, has large, somewhat flattened, curious blue-green ears, and the straw is often almost solid instead of being hollow like the others. It grows into a large plant, the straw being four or five feet high, but only gives a small yield of grain. This species is supposed to have originated in Spain, in which country it is still cultivated on a large scale. We will now proceed to describe the general mode of cultivation of wheat. The World's Commercial Products The soil to which the farmer entrusts his seed must possess certain qualities. Then the plant must be able to extract a sufficient quantity of moisture from the soil, although ,this need not be abundant. Clays and heavy loams are the best soils on which to grow wheat ; but with skilful farming and selection of the proper varieties, good harvests are obtained on light sandy soils. If the ground is too wet, the corn lacks vigour, and the production of seeds is small. If, on the other hand, sand predominates, the ground is too permeable and does not hold the quantity of moisture that is absolutely necessary for the growth of the wheat, which then thrives very badly. It will not do, says the farmer, to accommodate oneself to the soil, but the soil must be accommodated to the plant. When necessary, its nature may be modified by the addition of different kinds of manure, that is to say, by adding the elements which it lacks. Thus, it is necessary to add lime to sandy soils, and as a rule marl — that is, a mixture of chalk and clay — is used for the purpose. If one has to deal with a soil in which clay is lacking, very clayey marl should be taken. The element that is added to the soil must not only modify its physical nature by giving it greater density, or, on the contrary, greater looseness, but it must also, by its chemical com- position, increase the chance of successful cultivation. Marl fulfils both these conditions. It sometimes happens that the sub-soil contains the elements which are wanted in the top soil. In that case the land must be deeply ploughed, the sub- soil being brought to the surface and thoroughly mixed with the upper layer. To put the matter briefly, the essential elements are the indispensable elements of These elements have to be Chalk Sand Clayey Sand Clay THE RESULTS OF WHEAT-GROWING UPON VARIOUS SOILS (1) sufficient but not excessive moisture, (2) lime, and (3) plant food, such as nitrogen, phosphoric acid, and potash furnished by natural or chemical manures, if it is proved by analysis that the soil does not contain them in sufficient quantities. Thus, the fundamental principle of a rational culti- vation of wheat is to know the physical and chemical conditions of the soil thoroughly, a knowledge which enables the farmer to modify its composition in a judicious manner. The great advantage of chemical manures is that it is possible to give greater richness to the soil by the addition of small quantities of material, but they should be used with care. They cannot, however large the quantities added, replace the natural manure, that is, farmyard or, as it is often termed in the tropics, pen-manure. The latter is the manure par excellence, improving both the physical and the chemical conditions of the soil, and increasing its water- holding powers, owing to the organic matter or humus it adds. The land on which wheat is to be grown must be thoroughly cleaned, for the plant is easily choked by weedy growths. Therefore, wheat is usually sown on a field on which a crop has 8 The World's Commercial Products jSPfi OTfc REAPING IN RUSSIA been grown which kills the weeds, such as beetroots or turnips in the north, and tobacco in the south. Different plants have different needs; one requires an abundance of nitrogen, whilst another takes more potash or more phosphoric acid out of the soil. Hence it may be easily under- stood that if the same variety were grown on one field for several successive years, it would soon have exhausted the element which it particularly requires. Therefore different varieties, which do not require the same elements in the soil, are grown one after the other. This is called rotation of crops. Take as an illustration the Norfolk or four-course rotation : clover or grass is grown the first year, wheat or oats the next, turnips, mangolds, or potatoes the third, and barley the fourth. Sometimes the farmer allows the field to lie waste for a year, without sowing or planting anything, in order to rest the soil. Such fields are called fallow-land. Many other rotations are practised, depending on the character of the soil, climate, amount of stock kept, and special requirements. The soil must be in the proper condition, neither too hard nor too soft. The farmer must try to obtain the golden mean : he must be well acquainted with the properties of the soil, with the climate, and with the capacities of his tools. Hence methods of cultivation differ, according to soil, climatic conditions, etc. The tilling of the soil comprises all operations of which the purpose is either to aerate it, thoroughly to mix its different elements, or to remedy its physical defects. The soil is turned over with the spade, the hoe, or the plough ; it is harrowed to break up the clods, and to put it in better tilth, and rolled, if necessary, to give it greater firmness. The importance of these operations varies with the nature of the soil, and with the variety of the wheat grown. The time when the wheat must be sown also varies according to its kind and according to the part of the world where it is grown. Generally speaking, we may say that wheat does not thrive if the temperature is below about 55° F. for three months or so of the growing period. It is impossible to fix a date for the sowing, for that is a question to be determined by expe- rience, and varies greatly according to local conditions. The farmer must be very careful in his choice of seed. It is of no use to have good land, to till it well, and then to sow seed of an indifferent quality. He can only expect a good harvest when the grains are heavy, well- developed, and thoroughly ripe. Wheat to be used for seed should not be reaped before it is Wheat 9 quite ripe and should be kept spread out on the granary floor as long as possible. In order to obtain seeds which unite all these qualities, the grains from the finest ears are laid aside as soon as the harvest has been threshed ; this is the first selection. These grains are first passed through the winnower, which takes out the dust and light grains. Mixed with the corn, however, there may also be seeds of other plants, the growth of which might afterwards do injury to the wheat. These must be taken out ; this is the task of the sifter and the bolter. But still the finest-looking grain, having the right weight and the right shape, may, notwith- standing the most energetic winnowing and the repeated shocks of the bolter, contain in the folds of the furrow which runs on one side of the seed the germs of diseases, the spores of fungi which might develop and spoil the whole crop. It is prudent to prevent this by destroying the germs without killing the embryo of the future plant ; this is done by liming or by treat- ment with copper sulphate. In the former process a liquid mixture of lime and water is thoroughly mixed by continual stirring, and poured on the seed, which is energetically stirred with a spade to enable every separate seed to come into contact with the disinfecting liquid. This method is chiefly followed on small farms, but the copper treatment is most generally practised. The seeds are sprinkled with a solution of sulphate of copper or blue vitriol, or preferably the grains are completely immersed in a receptacle containing this solution. Immersion has, in addition, the advantage of allowing a last selection to be made, for the grains which are too light float on the surface and are easily removed. The disinfection should be accomplished little by little, for a heap of wet corn, although it is aired by continuous agitation with a spade, grows warm, and soon commences to sprout. Wheat is sown either broadcast, by hand or by a sowing-machine, or by means of a drill, which buries the seed in the soil at regular and equal distances. When broadcast sowing is adopted, the harrow is passed over the field, making light furrows into which the seed disap- pears. But many grains remain on the surface, and are killed by frost or heat, or are picked up by birds. This method is therefore usually only carried out on small farms, where the plot is too small to allow a sowing-machine profitably to be employed. On large farms sowing-machines are generally used. There are two kinds : (a) those which sow broadcast, and (b) drills, which distribute the seed over the light furrows or drills they make in the soil, and cover them over at once. The work of these latter machines is -_ £. '„ - ~ ~ „ - perfect, and large quantities of seed are saved by using them, only about half as much seed being required to sow an acre with a good drill as when sown broadcast. The money spent on a good machine is accordingly soon repaid. Once the seeds have been buried in the soil, their development begins. About a fortnight after the sowing the first leaves appear ; their number increases, and the field looks as if it has suddenly become a meadow, with here and there a bare spot, where for some reason or other the wheat is late, or perhaps does not appear at 10 The World's Commercial Products STACKING THE CORN FOR FEAR OF RAIN all. The young plant con- tinues to grow without any check until, with autumn - sown wheat, the frost sets in, and continues again as soon as that is over. If, however, the frost is too severe, the wheat dies and the farmer is obliged to sow summer wheat in March. Again, during winter, the roots may be laid bare. The wheat soon dies if this state of things is not remedied by rolling, which again makes the soil hard and flat. Sometimes, also, the corn comes up bleached or yellow. This is often the case in a cold spring, and very thin liquid manure or nitrate of soda should be added. Very soon its beneficial influence will be seen, and the corn regains its vigour. But other plants besides the corn take advantage of the nourishing elements with which the soil has been enriched, and if left alone would soon grow up so luxuriously as to stifle the wheat. To get rid of these the field must be thoroughly weeded ; when the wheat has been sown broadcast this must be done with the hoe, but when it is sown with the drill the weeding is done with a horse machine. This rough outline indicates in a general way the methods adopted in sowing and growing corn, but the details vary according to the country and to the extent of the fields, although the object aimed at is always the same. On small farms simple ploughs are used, but on the huge farms of the United States, Australia, Canada, Argentina, ploughs cutting eight or even as many as twenty-four furrows at once are employed. These are either drawn by animals or by steam power. The tilling on these large farms is, of course, done less carefully, but much more quickly. The sowing is carried out with ten or twenty machines, and a whole army of farm-hands work on the fields. Everything is done quickly, and the often still virgin soils are so rich that the harvests are abundant, and all those precautions, which are necessary elsewhere, need not be taken. The wheat shoots up under the influence of the alternate rain and sunshine of the spring,, finding in the soil and in the air the elements necessary for its growth. All the nourishment accumulated by the roots or elaborated in the leaves mounts to the ear and is devoted to the development oi the grain. When these have acquired a certain firmness, which the farmer often judges with his finger nail, the corn is ready to reap. The farmer does not always wait until the wheat is ripe before he reaps it ; mowed while it is- still green, wheat makes excellent fodder, and in some countries is grown solely for this purpose. The importance of the different agricultural processes included in the one word " harvest " varies with the extent of the farms. The tools used are not the same everywhere ; here men and women wield the simplest kind of reaping-hook, while children follow, gather the haulms, and spread them out on the field to dry. This is the harvesting of small farmers, and this same method is. also followed when the wheat has been laid flat by wind or rain. More frequently the reaping is done with the scythe, which works more quickly and neatly. If the extent of the fields and the farmer's means allow it, reaping-machines are used, which, drawn by horses, cut down the wheat over a breadth of about five feet every time. The: Wheat 11 reaping-machine cuts off the haulms and throws them down at regular intervals, and the binders gather two or three of these heaps together to bind them into sheaves. But still more perfect machines exist, which both cut the haulms and bind them into sheaves. These are the self-binding machines, and only. one man is wanted to drive each machine. On the immense corn-fields of the Far West, the Americans have for. some time been successfully using gigantic, very ingeniously constructed machines, called " harvesters," which, drawn by twenty-four to forty horses, travel through the miles of corn, cutting out a track up to twenty feet wide, reaping, cleaning, and threshing the wheat, putting it into bags, a long line of which it leaves behind. Portable factories we might well call these huge machines, besides which the self-binding machines look like toys. Still larger harvesters are drawn by huge traction engines, and, as giving an idea of their capacity, some of those in use in California cut over forty feet at once, and harvest and leave in sacks ready for export the crop from as much as 120 acres in one day. Eight men are required to work such a machine. After the harvesting the corn may be taken to the rick or to the barn, but the sheaves must be thoroughly dry, for if heaped up while wet, heat is developed, which causes both corn and straw to ferment, and hence to be spoiled. After the stacks have been constructed, or the sheaves have been taken to the barn, a privilege which is as old as the world allows the poor people to come and glean the ears which are left on the field. The picturesque silhouettes of the gleaners, stooping over the stubble and picking up the forgotten ears, have often tempted painters and poets. Threshing, or separating the grain from the ear, is the next process, but as a rule this is not urgent, unless the farmer can obtain a higher price for his corn immediately after the harvest. o£ the Orinoco. I find no proof that it is indigenous in Guiana, although it seems probable. : Many early writers indicate that it was. wild and cultivated at the time of the discover^ of America from Panama to Guate- mala and Campeachy, but from the numerous quotations collected by Sloane it is to.be feared that its wild character was not sufficiently verified. It was perhaps introduced into Central America and into the warm regions of Mexico by the Indians before the discovery of America. Cultivation may have naturalised it here and there, as is said to be the case in Jamaica. In sup- port of this hypothesis, it must be observed that Triana indicates the cacao as only cultivated in the warm regions of New Granada, a country situated between Panama and the Orinoco valley. However this may be, the species was grown in Central America and Yuca- tan at the time of the dis- covery of America. The seeds were sent into the high- lands of Mexico, and were even used as money, so highly were they valued. The custom of drinking chocolate was universal. The name of this excellent drink is Mexi- can. The Spaniards carried the cacao from Acapulco to the Philippine Isles in 1674 and 1680, where it succeeded wonderfully. It is also culti- vated in the Sunda Isles. I imagine it would succeed on the Guinea and Zanzibar coasts, but it is of no use to attempt to grow it in countries which are not very hot and very damp." The forecast of De Candolle, based on his knowledge of the geographical distribution of plants, that the cacao plant would probably thrive on the Guinea coast, has been verified to a degree probably beyond his utmost expectations, in the extraordinary development, as is shown below, of the industry in San Thome and to a less degree in the Gold Coast Colony and the Cameroons.

In 1903 it held second place, in 1904 it was third, and in 1905 it actually sur- passed Ecuador, and attained the premier position. VARIETIES OF CACAO An enormous number of varieties of cacao are recognised and distinguished by local names in various parts of the world. By permission of Messrs. Cadbury Bros. The mQst authoritative modem aCCOUnt, embracing all the world's forms, is that of Dr. Preuss, who has travelled through most of the cacao-producing countries, and spent much time in examining the different races. He finds, however, that it is impossible to set out in a table the differences which distinguish all the varieties, and that those of each country must be con- sidered separately. The chief charac- teristics used for distinguishing the varieties are the shape, external appear- ance, and colour of the pods, and the colour of the interior of the beans or seeds. A classification of the Trinidad cacaos was drawn up in 1882 by Dr., now Sir, Daniel Morris, K.C.M.G., the Commissioner of Agriculture for the West Indies. From Trinidad cacao was sent to Ceylon, and the Ceylon varieties have recently been the subject of study by Mr. R. H. Lock, and his key to the varieties published in the Circulars and Agricultural Journal of the Royal Botanic Gardens, Ceylon, is given below. This is substantially that originally drawn up by Sir D. Morris, and thus embraces the West Indian and East Indian cultivated forms. The two main groups are Criollo and Forastero. Criollo Varieties, character- ised by plump, pale coloured seeds, contained in a rela- tively thin-skinned pod, which is usually rough with a pointed apex. Forastero Varieties include all which are not Criollo; the beans vary in colour from pale to deep purple, the lat- VARIETIES OF COCOA ter being bitter in taste and Cacao Forastero r «•« By permission of Messrs.

Pods ovate, nearly smooth, usually bottle-necked ; beans of lower - quality, usually flat, and all purple. (•6) Calabacillo. Pods ovate, % smooth, small, not bot- tle-necked ; beans small, flat, and all deep purple. The illustrations of Criollo, Foras- tero, and ' Calabacillo pods, entire and' in -section, will 'serve to render clear some of these characteristics. Of each of these kinds there is a yellow and red variety, dis- tinguished in naming- by the addi- tion of dmarilio (yellow) or Colorado (red) fo the first name. Thus we have Forastero, variety Cundeamor amarillo, and Forastero, variety Cun- deamor Colorado, and so on. ■Mr. J. H. Hart, Superintendent of the Botanic Gardens of Trinidad, whilst agreeing with this classifica- tion in the main, regards Calabacillo cacao as a class by itself, and not merely as a variety of Forastero. The varieties differ also in hardi- ness. Calabacillo is the most vigor- By permission of ous trer, and will grow under the ceylon. worst conditions, but its produce is much inferior to the others. Forastero is intermediate in hardiness and value, whilst Criollo is the most delicate tree, and yields the beans of the greatest value. As in the case of the sugar- cane, the distribution of plants from one country to another has resulted in great confusion in the naming, and it is exceedingly difficult to correlate the varieties of different countries. Cultivation General Conditions. Cacao is not a plant which will thrive under any conditions ; on the contrary, it is very exacting, and considerable knowledge of its requirements is necessary in order to choose a proper spot. Deep alluvial soil, well-watered but well drained, in a sheltered Messrs. Cadbury Bros. A HILL CACAO ESTATE Cacao or Cocoa 121 locality, are what it likes most, and these must be found for it in a thoroughly tropical climate. Many parts of the West Indies, although quite tropical, and with sufficient rainfall, are absolutely unsuited to cacao. In Barbados, for instance, although sugar-cane, cotton, and other crops which are regarded as distinctly tropical, can be grown all over the island, there are extremely few places suited to cacao. Strong winds are particularly injurious, and Barba- dos being in the track of the " Trades," it is only in a few sheltered valleys, with other desirable attributes also, that the plant can thrive. Accordingly it is not altogether surprising that amongst the British West Indies we find only Trinidad, Grenada, Jamaica, St. Lucia, and SURINAM. YOUNG CACAO PLANTS SHADED FROM THE SUN Dominica figuring in the list of cacao-producing countries. These are all mountainous, well- wooded islands, whilst the more bare and exposed islands such as Barbados, Antigua, etc., are, speaking generally, unfitted for the crop. Mr. J. H. Hart, referred to before, in his useful book, " Cacao," says : " The ideal spot in which to found a cacao plantation is a well-sheltered vale, covered with large trees, protected by mountain spurs from the prevailing winds, well watered, and yet well drained, with a good depth of alluvial soil on which rests a thick deposit of decayed vegetable matter; easy of access, and in a district distant from lagoons or marshes for the sake of the proprietor's health. Such a spot in a climate similar to that of Trinidad could not fail to produce regular crops of the finest quality of cacao." Planting. The ground having been cleared of the original forest, planting can be proceeded 122 The World's Commercial Products By permission of CEYLON. Mesm. Cadbitry Br NURSERY OF CACAO SEEDLINGS IN BASKETS OF PLAITED PALM LEAF •with, and two methods may be adopted. The seeds can be sown in nurseries and kept there until young plants a foot or so high are available, or seeds may be sown in the ground, where future trees are desired ; the latter method is called M planting at stake." The young plants have to be carefully shaded in either case. In a tropical nursery, bamboos cut up into lengths, ■each consisting of one joint, form excellent pots, and are extensively employed. Plaited palm-leaves also form useful " flower-pots." The young plants are carefully tended until of .sufficient size, and then planted out and carefully shaded from the sun, during a season when they will get showers to give them a good start in life. When the seed is sown at stake three seeds are planted in one hole ; the holes are made .at a distance of four to five yards apart in all directions. Many of the seeds will probably not germinate, however, owing to various causes, but of the plants which do come up the weaker, ones are pulled out for the benefit of the stronger specimens. When they are a little •over three feet high, they are pruned, in order that the trees may attain a pyramidal crown. Shading. Cacao trees raised from seed, whether in nurseries or in the open, require to be protected from the sun, when placed in their permanent positions. This is usually afforded by growing bananas, pigeon peas, cassava, or other temporary crops between the rows of young plants. They supply the requisite shade, and, moreover, yield crops, and bring in returns during the five or more years of waiting for the cacao to mature. This temporary shading is quite distinct from the use of permanent shade trees. In many countries cacao thrives better under the light shade of taller trees and those nearly always used are various leguminous trees which we may speak of collectively as Bois immortel (Erythrina, spp.) or Madre de Cacao (Mother ■of Cacao), to use the Spanish name. These are planted at proper distances amongst the young •cacao, and kept there permanently even when the cacao is fully grown, when the temporary shade plants-have long since been removed. • Fruiting. Trees about five years old bear fruit. These are at first green, turning red and yellow as they ripen, and when dried their colour becomes a chestnut-brown. They are attached to the stem or branches by a short stalk, and are somewhat like very thick cucumbers 123 124 The World's Commercial Products in shape, about eight or more inches long, and three or four inches in diameter. The process of blossoming and bearing fruit is completed in about four months, and is continued throughout the whole year ; hence fruits may be gathered at any time of the year, although at certain seasons the principal crops are obtained, for example, in the West Indies in December and January, during the early part of the dry season. Picking. The fruit which is hanging low enough to reach it with the hand is gathered by carefully turning it round until it breaks from the stalk ; those which cannot be reached are cut off from the stem and branches by means of a curiously shaped small knife fastened to a long stick. The gathering requires great care, as the buds and blossoms, which are to bring forth the next harvest, are easily injured. Neither unripe nor over-ripe fruits yield a good product. The picker judges by the colour n W i 1 '-' i 't& V*Jt \m y /. J 3k n T *3»3I % \ CACAO FRUIT The Beans of two laid bare whether a fruit is ripe or not ; moreover, the ripeness may be ascertained by the accustomed ear by tapping the ' pod. The rind of the pod is by nature firm, a little woody, but becomes leathery when dried. Each pod contains some sixty seeds, arranged in five or eight rows (mostly five) ; the seeds are white when they are fresh, but brown and covered with a fragile skin or shell when dried. These seeds* which are not unlike beans or almonds, are imbedded in a mass of mucilaginous pulp, of a sweet but acid taste. The seeds only require to be extracted, cured and dried, to become the cacao-beans of commerce. Breaking. The pods are left on the ground by the pickers and collected up by women and children into heaps to be opened. This operation is known as "breaking cacao." The .pods are often opened with a cutlass,,which should not be too sharp. Care is needed so- as just to cut through the rind and- not injure the seeds. The opened pod is taken and the slimy mass of seeds and pulp scooped out with the fingers, and finally conveyed to the curing house in baskets, sacks, Qr other convenient means, with or without the aid of mule or donkey carts, according to the nature of the estate and other circumstances. The empty rinds are left in heaps on the field to rot and help to fertilise the soil. In case of attack' by some of the fungoid- diseases it is very incautious to leave the pods above ground, as they only form nurseries for the propagation of disease. In these cases the best course is to bury them. Cacao or Cocoa 125 Fermenting. The fermentation of the beans is a very important operation and requires considerable care. The modus operandi varies according to the kind of cacao, to the local usages, and to the planter's views. As a rule the wet cacao-beans are put in a sweating-house specially built for the purpose, and divided into small compartments opening on to a common space, by means of movable partitions so that it is readily possible to transfer beans from one compartment to another. The flooring of the house is important — unevenness of any kind is to be avoided as rendering the beans liable to damage by being crushed when shovelled from one place to another. Cement, iron, pitchpine or other resin-containing timbers will not do, owing to the acidity of the juice. A good method is to have an upper flooring of laths placed lengthwise to the direction of shovelling. The juice from the beans escapes between the laths onto a water-tight floor below arranged with a central exit drain. The cacao heaped up in the compartments must be turned every twenty-four hours, in order to cause a regular sweating. If this turning can be done twice a day it is still better, for the looser the beans are lying on one another the more regular the sweating, which destroys the slimy substance which covers the beans. Three days are usually quite long enough to complete the fermentation process. On some plantations there are no sweating-houses, but the beans are thrown into large SURINAM. YOUNG CACAO TREES IN THE SHADOW OF BANANA TREES 126 The World's Commercial Products heaps on the barn-floor to sweat. Another method is to let the cacao-beans ferment in a basket lined with' banana leaves. Fermentation affords the most convenient method of getting rid of the mucilaginous pulp which surrounds the freshly gathered seeds. Internal changes also take place, and the seeds lose to some degree the bitter taste they formerly possessed. The pale-coloured seeds of Criollo cacao become of the nice cinnamon-brown colour so appreciated in the market, whilst the deep purple colouration of Forastero and Calabacillo cacaos is also modified. Another change of some importance is that the skin or shell of the seed becomes tougher and so facilitates the subsequent handling, and helps to pre- serve the contents from the inroads of fungi. In some countries fermentation is not practised, but fermented cacaos fetch better prices in the market than the unfermented product. Washing. Opinions differ as to the advisability of washing the beans after they have been fermented. It is generally practised in Ceylon, in the Cameroons, and else- where, but not so in the West Indies, for instance, in Trini- dad. Amongst the advan- tages claimed are that it readily removes the remain- ing portions of the pulp and allows the beans to dry more rapidly. Planters who do not favour the practice appear to think that the method in- volves more trouble than the increase, if any, in the price warrants. Drying. Whether the beans have been washed or not they have to be dried. The methods of drying cacao> practised in different countries or by individual planters in the same country vary considerably. They may, however, be resolved into two groups, according to whether the heat of the sun is relied on or whether artificial heat is resorted to. With a very small crop,, such as a peasant proprietor would obtain from a few trees, the beans can be spread out on the ground or on a tray or piece of matting or cloth, which can readily be picked up and placed under cover should it rain. For a large crop this is impossible unless the seasons are so regular, as, of course, they often are in parts of the tropics, that cbntinued fine weather can be relied on. A great advance on this method is to spread the beans out in a thin layer on large platforms SHADED CACAO TREES Cacao or Cocoa 127 mounted on wheels, which run on rails. There is a house adjoining, and each fine morn- ing the platforms with their loads are run out, and can be hurried under cover in a very few minutes if necessary. The heat of the mid-day sun is sometimes so great that it would not be wise to allow the cacao to remain exposed the whole day. The alternative method is to make the platform stationary and have a movable roof. This is the method generally adopted in Trinidad, although the former is also largely employed. A drying-house of this character is shown in a picture in the next part. Economy of space can often be effected by combining the two methods. We may have- a fixed platform sufficiently raised to allow one, two, or more tiers of i movable trays to be protected under it, whilst a sliding roof, in one or two portions, can be used to cover the fixed platform at will. Such an arrangement, in use on one of Messrs. Cadbury's estates in Grenada, is shown in the illustration on p. 128. Artificial drying-houses are of various types. One of the most successful may be called the Ceylon drier, and a house of this pattern was some years ago built by the Imperial Depart- ment of Agriculture for the West Indies at the Botanic Station, Dominica. Hot air is made to pass in succession over and around a series of trays, arranged one above the other, and in such a house cacao can be dried in twenty-four hours, instead of requiring a week or so- as when dried in the sun. Another pattern of drying apparatus which has recently attracted considerable attention in the West Indies is that patented by Mr. Hoadley, of Chaquanas Estate, Trinidad. The following description of his invention is taken from the West Indian Bulletin, Vol. VI (1908), p. 80: "The cacao-drying apparatus consists of an ordinary room, thirty-four feet square, with twenty-five feet perforated circular drying floor, upon which cacao is placed direct from the fermenting box. In the centre of the drying tray is a vertical axle from which pro.je'ct four arms which are revolved once in ten minutes. To each arm are attached six ploughs, the operations of which are- equal to the work of twelve coolies in keeping the cacao in constant motion. Hot air is generated by exhaust steam which is passed into 1,100 feet of piping enclosed in a box, over which cold air is drawn by a powerful fan which, makes frofn. 600 to 700 revolutions per minute. The air in its passage becomes heated to any ^desired point up to 150° F., and is forced up through the drying floor. The machine will dry from twelve to fifteen bags of cacao in thirty to thirty-six hours. The cost of installing the system is said to be between £300 and £400." A Trinidad bag of cacao weighs about 170 lbs. Colouring. Cacao beans are appreciated of a good colour and of bright clean appearance. Sometimes uni- form colouration is secured by mixing with the beans a small amount of red earth or clay, or even annatto. This, however, is by no means a universal practice. Polishing. During damp weather the cacao if left in a heap tends to become mil- dewed on the outside. This can be prevented or got rid of by the gentle rubbing of the beans against one another, GATHERING THE FRUIT 128 The World's Commercial Products and frequently such rubbing also serves a useful purpose in finally cleaning the beans, and removing the last traces of adherent pulp. This is particularly so in places where washing is not resorted to. A simple method of obtaining these desirable results is that known as " dancing cacao," an illustration of which is given on p. 130. A heap of beans on a drying floor is shown, and in the middle are a number of men engaged in treading the produce with their naked feet. The three men at the sides with shovels keep returning to the centre the cacao which during the operation naturally tends to become more and more spread out. The result is to remove mildew, etc., and to give a final polishing to the beans. Dancing is comparatively expensive, and in Mr. Hoadley's apparatus described above there is an additional machine which clays and polishes the beans, or merely polishes them according to special requirements, and thus does away with this process of " dancing." By permission of Messrs. Cadbury Bros. GRENADA, B.W.I. SAMARITAN ESTATE Packing and Shipment. The cacao is now ready to be shipped. It is most important that it is thoroughly dry, beyond that no special care is requisite. The beans are put into bags, or sometimes barrels, and can at once be placed on board ship. In Europe Hamburg is now by far the most important port for cacao, a position which it attained in 1904, previous to which Havre had occupied the first place. London occupies the third position. The other great port of the world for the reception of cacao is New York, which yearly increases its import of this crop, and is now about equal to Havre, and receives annually nearly twice as much cacao as London does. CACAO AS A FOOD-STUFF Before entering on a description of the processes through which the raw cacao-bean of commerce passes before it reaches the consumer either as cocoa powder, chocolate, or in other forms, it will be advisable to note the composition of the beans, as then we shall be in a position to understand better the mode of manufacture. Cacao or Cocoa 129 The contents of the cacao-beans are just as in other seeds the food-reserve the mother-plant has put by for the young plants to live until they are able to subsist by themselves. The seeds of the cacao plant contain albuminoids or nitrogenous substances, starch, water, fat, sugar, cellulose and mineral matter ; also the alkaloid theobromine, and a colouring matter called cacao-red. According to Payen the average composition of good West Indian beans is as follows : — Fat (cacao-butter) . . . . . . . . 50'0 per cent. Starch Albuminoids Water Cellulose . . Mineral matter Theobromine io-o 20-0 120 2*0 4-0 20 100-0 On account of the high percentage of nitrogenous materials, fat and starch, which it contains, the nutritive value of cacao is great, and the alkaloid theobromine gives it stimulating properties also. This stimulating effect of cacao is increased by the volatile oil developed during the process of roasting, and to which cacao owes its characteristic aroma. It will have been noticed that the bean contains approximately half its weight of fat (known when extracted as cacao-butter). This, with the other constituents, renders the beans very ' .'.-■. -A " •; -r : ' ■ t ; N y* \ ** S '*&?■•*•' ^"4-jst TURNING THE BEANS 130 The World's Commercial Products nutritious, but too fatty to suit many people's taste. One of the first operations in the prepa- ration of cacao is to get rid of the greater portion of this fat. It is not that the fat is harmful or indigestible, but simply that there is too much- of it for ordinary purposes. The fat may be separated from the beans in two ways. In factories it -is effected by means of hydraulic presses, and an important by-product is obtained, worth about double the mar- ket-value of an equal weight of the raw beans. In this way only a portion of the contained fat is extracted from the beans, but by chemical processes it is possible to extract it all. By boiling the cacao wit1 \ water or by grinding the beans to powder and treating them with ether or carbon bisulphide, the whole of the fat can be removed. " DANCING CACAO BEANS IN TRINIDAD One method of lessening the proportion of fat is by adding starch, but whilst the fat is relatively reduced in this way, the percentage of the other useful constituents of the cacao is reduced also, with loss of its agreeable fragrance and stimulating properties. A Dutchman, Mr. C. J. van Houten, of Amsterdam (1801-1887), the founder of the well-known firm bearing his name, endeavoured to solve this question of the excess of fat, and after long searching he succeeded in not only freeing the beans from the superabundant fat, but also in giving such a form to the mass which remained after the process that the cacao retained all its nutritive power, and could be easily made into an agreeable beverage. At first he- called his product chocolate-powder, a name which was soon changed into Van Houten's cocoa — to indicate that the product only contained the pure elements of the cacao- beans, and was not mixed with starch or any other added substance. 131 132 The World's Commercial Products SURINAM. A SWEATING BARN (EXTERIOR) We are accustomed to call cacao soluble nowadays be- cause it apparently dissolves in hot water or milk ; how- ever, soluble ' is the wrong word to use, as there is no solution in the ordinary sense as, for instance, in speaking of sugar or salt being soluble in water or milk. In reality the discoverer, Mr. C. J. van Houten's purpose was to pre- pare a powder which should be completely miscible in liquids. It is a sign of com- plete diffusion that the cacao after boiling water has been poured on it forms hardly any sediment at the bottom of the cup. Cacao or cocoa butter, the extraction of which is described elsewhere, is, when quite pure, a white, rather hard fat, with an agreeable odour of chocolate, and a delicate taste. It melts slowly in the mouth. Its melting-point is about 85 to 90° F., and its specific gravity varies between 0"85 and 0'98. It is only slightly soluble in warm alcohol, but may be completely dissolved in ether. Cacao- butter does not turn rancid if carefully stored, which property renders it very valuable for pharmaceutical and other preparations. When fresh it is yellowish- white, but becomes quite white on keeping. Cacao-butter is frequently used in the preparation of perfumes and cosmetics. The fresh butter is used in ointments, cerates, and plasters. Moreover, cacao-butter is a constituent of almost all pomades, and consisting of stearin, palmi- tin, and olein, it makes an excellent soft toilet soap, of a beautiful white colour, when mixed with certain alkalies. The so-called " chocolate- fats " are frequently derived from coco-nut oil and palm oil, and are used to adul- terate cacao - butter, being much cheaper. It is to the cacao-red and the volatile oils that the beans owe their colour, peculiar aro- ma, and to a great degree their characteristic taste. The amount of theobromine con- tained is comparatively small, and yet to it cacao owes its stimulating action. In 1840 SURINAM. A SWEATING BARN (INTERIOR) Cacao or Cocoa 33 Wosscressenzky succeeded in separating the alka- loid theobromine from the beans ; he found that chemically it differed little from caffeine and theine, the active principles of coffee and tea, whence it is that the physiologically stimulating effect of cacao, coffee, and tea is very similar. .Those substances which are known in chemistry under the name of alkaloids are often very poisonous. Theine, caffeine, and theobromine act as poisons when they are consumed in large quantities. Chocolate is a mixture of cacao with sugar, and as a rule with spices also. Usually one part of cacao is mixed with one part (or \\ part at most) of sugar. Cheap chocolate often contains admixtures of starch, such as corn flour, wheat, rice, or potato starch, etc. ; powdered roasted acorns, chestnuts, earthnuts, chicory, ship biscuits, the ground shells of the beans and other woody substances, and even plaster have been employed as adulterants. In England some brands of cacao contain starch, but this fact is, or should be, stated on the tin, so that it loses the character of adulteration, and, moreover, the price is lowered in proportion. The cacao of some of the most important factories in Holland has been found to contain twenty-nine to thirty per cent, of fat, fourteen to eighteen per cent, of albuminoids, five to nine per cent, of ash, four to five per cent, of water, 06 to 1*5 per cent, of theobromine, the rest consisting of starch. Thus it is seen that the composition varies, but these figures may be taken as the limits which " pure " cacao-powder may not exceed. In the preparation of medicines chocolate is often used to disguise the taste of disagree- able drugs. Thus, chocolate is sometimes mixed with quinine, rhubarb, steel preparations, magnesia, calomel, ipecacuanha, santonin (the well-known worm-cakes for children, which are still manufactured in large quantities in some Dutch factories to be exported to China> where children seem to be very much plagued with ascarids), castor-oil, etc., and tabloids or cakes are made of these mixtures, containing certain quantities of these drugs. 134 The World's Commercial Products STONE DRYING FLOOR WITH MOVEABLE ROOF THE MANUFACTURE OF CACAO AND CHOCOLATE Until the latter part of the eighteenth century the fabrication of chocolate was chiefly effected by manual labour, the beans being pounded to powder in an iron mortar. Even to this day, the Chinese cook in the Philippine Islands, who makes the cacao-beans which are grown there into chocolate, carries his whole factory about with him. This consists of a small wooden table, made to rest on the knees of the man, who squats down, and on this table the shelled beans are pounded in a small marble mortar with a heated pestle, and the mass is kneaded to chocolate-dough with sugar, pepper and other favourite spices. With the exception of such cases as the latter, manual labour has been replaced as a rule by wonderful machines ; the first of which was put into practice in 1778 by M. Doret, of the medical faculty of Paris. These machines have been altered and improved continually, though the purpose which the engineers have in view always remains the same, namely, to grind the beans to a powder of the greatest possible fineness, and to mix it as intimately as possible with substances such as sugar and flavouring materials. Whether a chocolate-factory is large or small, the cacao-beans always have to undergo the same essential processes. These chief stages are as follows: — (1) Sorting and cleaning the raw beans. (2) Roasting the cleaned beans. (3) Breaking and shelling the roasted beans. (4) Grinding of the roasted and broken beans and the addition of other substances such as sugar, spices, etc. If cocoa is being made the fat is extracted at this stage. (5) Moulding and packing. Sorting and Cleaning the Raw Beans The cleaning and sorting of the raw beans is of the greatest importance. The principal Cacao or Cocoa 135 object in cleaning and sorting the beans is to get rid of all foreign substances, such as sand, pieces of stone, etc., which later on might damage the rollers of the grinding-machine. Impurities also spoil the aroma of the cocoa when it is roasted and lower its solubility. The beans are cleaned by placing them in long barrel-shaped sieves which are made to rotate slowly. The meshes of the sieve must be of such a size that everything smaller than cacao- beans themselves can pass through. At the same time a draught created by powerful fans carries away dust. The sieves are so made that the beans are at the same time sorted into three groups — large, medium, and small. The material to be roasted thus consists of beans of equal size, which is of advantage because if beans of unequal size were roasted together the small ones would spoil by the time the large beans were sufficiently roasted. Roasting the Beans The beans are next exposed to a high temperature, that is to say, they are roasted. This roasting serves several purposes. First of all the aroma of the beans is increased and the starch is partially changed into dextrin, a substance which is more soluble in water than starch. The bitter substances which the beans contain are partly eliminated, the shells become dry and crisp, and the beans themselves dry, which renders them more easily ground. The flavour of the beans is greatly improved by the roasting. The roasting is carried out in large iron drums, each of which may hold a ton or more of beans. Coke fires, gas, or better, superheated steam are employed, and great care and judgment are necessary to obtain the best results. The temperature for roasting cacao-beans is not so high as that for roasting coffee ; experience has shown that the best temperature lies between 260° and 280° F. The beans should not be left too long in the machine, and they are turned continually. The iron boxes are accordingly made to revolve. The temperature in the boxes is carefully regulated, although it must by no means be constant throughout the whole process. The time required for roasting depends on the quantity of beans roasted at once and on the kind of beans. Therefore, the roaster should always be a reliable and experienced person. To prevent too great a loss of aroma and to cause the beans to be shelled more easily, they are cooled suddenly after the roasting is completed. Breaking and Shelling the Beans The roasted beans are now " broken down " and the shells removed. The beans are gently cracked and exposed to a powerful air-blast which can be regulated according to the coarseness or the fineness of the fragments ; a gentle wind is made to blow when the beans are broken into very small pieces, and a more vio- lent one when the pieces are bigger, so that the separa- tion of the particles of beans from the larger, but specifi- cally lighter, shells is effected with great accuracy. For the preparation of chocolate it is important to sift the broken beans once more, in order to get out the harder germs, the powder of which leaves a sediment in stone floor for drying cacao-beans in the open air 136 The World's Commercial Products the beverage. This is done mechanically by means of a very ingenious machine invented by the firm of J. M. Lehmann, of Dresden. The shells of the cacao-beans form the only waste product in cacao industry. As the shells form about twelve per cent, of the beans, it is desirable to find a use for them. Cheap chocolate often contains the ground shells, but for the better kinds they are useless, as they may rightly be said to be adulterants, although it is true that they contain some theobromine and some fat, and taste like cocoa. The ground shells are sometimes sold as " cocoa-tea," and find purchasers, especially in Ireland. As an article of commerce the shells are called ROASTING CACAO IN VAN HOUTEN S FACTORY " miserables " in England. They may be made more palatable by candying them with sugar, and in that state they are a favourite kind of sweetmeat for children, especially in the east of Germany. By treating them with benzine it is possible to extract the fat they contain, which is sold under the name of second Dutch cacao-butter ; however, the value is but small. These different uses consume but comparatively small quantities of the supply. Infusions of the shells of cacao-beans are sometimes employed to improve the taste of coffee- beans during roasting, and also to enhance the flavour of coffee-substitutes made out of corn or malt. Cacao-extracts are also made out of the shells, by boiling them with water ; the extract thus obtained is reduced by evaporation until it acquires a certain strength. This extract is not only used as a substitute for coffee and tea, but is also sometimes mixed with cacao and chocolate. \ 137 138 The World's Commercial Products By permission of Messrs. Cadbury Bros. THE PACKING ROOM, BOURNVILLE It was ascertained by experiments that the nutritive value of these shells is about the same as that of middling hay. Cattle soon get to like them, and experiments made with three groups of milch-cows were successful. After they had been fed with the new fodder for ten days the analysis of the milk showed an increase of butter and milk sugar ; and, moreover, an increase in the quantity of milk. In a report on the " Experimental Farms of Canada, 1898," the usefulness of cacao-shells as manure is pointed out. Grinding Formerly the beans, after having been roasted and broken, were ground several times before they were taken to the " melangeur " or mixing-machine, in which the mass was rubbed still finer and mixed with sugar. Machines with millstones or rollers are now 'used in which the cacao is ground to a liquid or thin paste owing to the heat developed by friction. One advantage of the reduction to the liquid state is that the sugar mixes much more easily with the cacao, and that an intimate infusion is more readily effected. This fusion is accomplished most successfully when the temperature is constantly kept at the same level, a little above the melting-point of cacao-butter, i.e., between 85° and 90° F. ; for this reason a mixing-machine is always provided with a steam-warming apparatus. In grinding the cacao to powder, as well as for a thorough mixing with sugar, it is necessary that the rotation of the hard granite cylinders, revolving in opposite directions, differs in rapid- ity. Therefore, the axles of these two cylinders, which have the same diameter, are provided with wheels with different numbers of teeth. So the cylinder attached to the wheel with the smallest number of teeth revolves more slowly than the one attached to the wheel with the largest number of teeth. If, for instance, one wheel has six teeth and the other twelve, the latter will turn twice as quickly as the former. The spices, volatile oils, or vanilla which chocolate contains as a rule are only added to the chocolate-mass {i.e.. cacao plus sugar) towards the end of the grinding process, in order to prevent a loss of perfume, which would certainly take place during a prolonged heating in the grinding and mixing machines. Of course, the cacao is mixed with sugar and spices, 139 140 The World's Commercial Products and in the case of some kinds of cheap chocolate with different kinds of meal, in different proportions. In general from fifty to sixty parts of sugar are mixed with from fifty to seventy parts of chocolate, with small quantities of the necessary spices either as powders or in alcoholic solutions of their volatile oils. If chocolate, composed of equal quantities of sugar and cacao, is too fatty, in consequence of the large quantity of butter contained in the beans, to be easily moulded into the forms wanted, part of the mass is replaced by an equal quantity of cacao- powder of the same mixture of beans from which the fat has partly been extracted. This is what is done in the case of expensive chocolate. In the case of cheap chocolate, however, the same end is attained by adding more sugar. If the chocolate-mass contains more than sixty per cent, of sugar, it is impossible to mould it into different shapes, and pure cacao-butter must then be added. In the preparation of chocolate-powder, or cocoa, as we are accustomed to call it, the partial extraction of the fat takes the place of the mixing with sugar. This extraction is effected by means of a powerful hydraulic press. A picture of one made by -the firm of Lehmann's, as used in Messrs. Cadbury's works, is shown. The mode of extraction is similar to that described for other oils in the section on that group of products. Three distinct products are found in the shops : — (1) Cacao nibs, simply the broken- up pieces of the roasted beans. (2) Chocolate, the ground nibs with the addition of sugar and flavouring materials. (3) Cocoa used for a beverage, the ground nibs with most of the fat extracted. The cocoa powder is put up in packets, tins, etc., and is at once ready for sale. Chocolate passes through various processes, and finally whilst still in the semi-liquid or pasty condition is cast in moulds, of any desired shape, so as to form tablets, croquettes, or fancy articles such as cigars, animals, eggs, etc. As is well known, chocolate is usually exceptionally well packed in order to preserve it in the best possible condition. During the different processes chocolate undergoes, especially during the grinding, air bubbles accumulate in the mass. In order to get these out, the chocolate is passed through a kind of press, which it leaves in the form of a cylinder, and subsequently is reduced to a certain thickness by a roller. The mass is cut into pieces each of the proper weight required ior a tablet. Of course, the weight of the tablets can be settled beforehand, and is precisely regulated by the size of the moulds, into which the pieces are pressed. The bottom of such a mould is as a rule divided by projecting lines, so that the tablet has corre- sponding indentures when it is taken out, which allows it to be easily broken up into so many parts. Simple chocolate-wares, meant for household use, are as a rule moulded into tablets or square blocks of different sizes and weights. The more expensive kinds of chocolate are also sold in these simple forms, and are made in the same way. The smaller tablets, "napolitains" labelling tins - f% 4 «0 Hfci ■ k— ** J BHfesyij§u n Kjp[ r ■dssvt 141 142 The World's Commercial Products MAKING BOXES FOR TRANSPORT — VAN HOUTEN S FACTORY and " croquettes," are made in this way. Other forms of chocolate are more often fashioned in moulds, consisting of two or more parts. Chocolate-cigars, for instance, are made in a double mould, consisting of two portions, each of which has the shape of half a cigar, the two halves fitting exactly together. They are however, sometimes made by pouring the liquid mass through hollow tubes. Chocolate-fishes and other such simple objects are made in a similar manner. Chocolate- eggs are as a rule made hollow — at least if they are not too small — by taking two moulds each in the form of half an egg-shell, filling them with a thin layer of chocolate, and uniting the two halves thus obtained to make one egg. Small tablets, fruits, and other objects filled with cream, are made in the following way : The cream filling is made, allowed to harden, and then dipped into the melted chocolate so as to receive a complete coating. Innumerable other varieties of chocolate and chocolate-coated sweets are made, and it would be impossible to enumerate them and describe their method of preparation here. It is important to note in comparing the three staple beverages, cocoa, tea and coffee, that only the first named can be regarded as a food. As has been pointed out, the whole cacao-bean is roasted and ground into such a fine powder that it remains in suspension in the water, so that it is all consumed. On the other hand, with tea and coffee all that is taken is an infusion or solution of the substances in the leaves or seed, as the case may be, which dissolve in the water. These form only a minute proportion of the products, and the remainder is thrown away. The stimulating principles are very similar in all three, but in cocoa we obtain these with the valuable nutritive materials in addition. of MILLING DEPARTMENT OF A CHOCOLATE FACTORY 143 144 The World's Commercial Products dw~ y^ TEA |Tea, as everyone knows, is prepared from the young leaves of the tea plant, Camellia Thea (Thea sinensis), a shrub belonging to the natural order Theaceae, and extensively cultivated in China, India, and Ceylon, and, to a less extent, in certain other countries^ Under the name- of Thea sinensis, the Swedish botanist, Linnaeus, originally described tea as a single species, but later it became known that two distinct plants were cultivated in China, which he named T. viridis and T. Bohea. These two species were long thought to be the origin of green and black teas respectively. No strictly wild plants have been found in China, but an indigenous tea-tree, Thea assamica (or, as it is now called, Camellia Thea) occurs in Assam, and is generally regarded by botanists as the parent species of all cultivated forms. Cfhe tea plant is a bushy shrub, which when left to its natural habit of growth and not subjected to the vigorous prunings necessary for its successful cultivation, attains the height of a small tree. The leaves vary considerably in size and shape, according to the variety ,_ but are leathery, alternate, and generally elliptical or lanceolate, with a toothed margin. Oil glands occur in the substance of the leaf and contain an essential oil to which the flavour of tea is largely due. The under surface of the young leaves is thickly covered with fine hairs which entirely disappear with advancing age. The beautiful white or rose-coloured ^ slightly fragrant, flowers occur either singly or in clusters in the axils of the leaves ; they '. are succeeded by more or less globular fruits consisting of capsules composed of three compartments, usually with only one seed in each compartment) The question as to the original home of the tea plant is by no= means settled, the point at issue being whether, after all, the true home of the plant is in the country naturally associated with it, viz., China, or in the neigh- bouring Indian province of Assam. The evidence in support of the latter contention is largely based upon the fact that the tea plant attains extraordinary A HILL-SIDE PLANTATION 0,4 145 146 The World's Commercial Products luxuriance in Assam, greater, it is said, than that attained in any part of the Celestial Kingdom ; and, arguing that in its natural home a plant reaches its greatest development, supporters of this view maintain that it is in Assam and not in China that we are to look for the home of tea. It by no means follows, however, that the reasoning of this argument is sound, for it has been repeatedly noticed that plants introduced into new countries where con- ditions seemed favourable for their growth have flourished so well that their luxuriance rivalled that of the plants growing in the land admitted to be their home^j Support for the opposite view is sought in a Japanese legend which ascribes to China the honour of being the home of the tea plant ; but, unfortu- nately, there is evidence for supposing that the Chinese never heard of this legend except from foreign sources, although the events related occurred in their own coun- try. ("There are, however, certain references to the plant in the writings of a Celestial author who lived about 2,700 B.C., and a Chinese commentator of this £i ancient author, writing in the fourth century B.C., calls attention to the mention of the plant, and adds that a beverage could be obtained from the leaves by adding hot water. It appears that the plant was used entirely as a medicine until 500 a.d., when it became a popular beverage. De_Candolle, however, in summing up the evidence on both sides, attaches considerable weight to the fact that apparently wild specimens of tea have been found by travellers in Upper Assam and in the province of Cochar, and adds that " the tea plant must be wild in the mountainous region * which separates the plains of India from those of China" ; he, however, regards the evidence as *■- tending to prove that the use of the leaves was introduced into India from the^lartrteT~CTJ^^fy^A Much more certain information naturally exists as to the date of the introduction of the product into Europe. There is a story which states that a package of a commodity hitherto unknown was received by an old couple in England during the reign of Queen Elizabeth, and that, instead of infusing the leaves and using the extract, they threw away the coloured PLUCKING TEA 147 148 The World's Commercial Products w"Wflft«-3ai PLUCKING TEA IN ASSAM liquid and ate the leaves after spreading them upon bread. ( Whatever may be said as to the probability of this story, it is definitely known that tea was introduced into Europe from China late in the sixteenth century, and that in 1657 a regular tea-house was opened in Ex- change Alley, LondonX From. this date tea began to be a regular beverage in England. It is mentioned by Pepys in his Diary ; under the date 28th September, 1660, we read : " I did send for a cup. of tea (a China drink), of which I had never drunk before," and, " Home, and there find my wife making of tea, a drink which Mr. Pelling the Pothicary tells her is good for her cold and defluxiOns." It .was at about the time of its earliest introduction into Eng- land that tea first became known in Russia, an embassy to the Court of Pekin bringing back some green tea to the ancient capital, Moscow. In 1664 the famous English East IndiaCornpaj lade a present of two pounds of teai.to the queen oT Charles Il^Catherine .of-&a^aTfza7and the product was still regarded as a rare delicacy. Fourteen years later the Company imported from China nearly 5,000 lbs. and towards the end of the century tea had ceased to be a. (7 ff At the present time the a1 |/thj « average annual export of tea from the countries producing it,, irrespective of the amount consumed in the countries themselves, amounts to about 1,108,828,000 lbs., of a value of over £16,000,000 sterling. Of this huge total, the British Empire is responsible for nearly 350,000,000 lbs., worth no less than £9,217,000, or considerably more than half the value of the world's total production. India heads the list with a. total . export valued at £5,830,000, followed by that of China, valued at £5,500,000. Im spite of this order of precedence, however, it should be noted that the actual quantity of tea exported from China is vastly in excess of that from India, being more than three times as much, but the quality of the product is very inferior compared with the Indian article, and hence the difference in value. Third in the list comes Ceylon Tea 149 with 150,000,000 lbs. worth nearly £3,390,000, followed at a long distance by Japan with 59,000,000 lbs., valued at^541,000, Java with 18,600,000 lbs., valued at £395,000, Formosa with 18,000,000 lbs., valued at £211,000, and Natal and the Caucasus with comparatively trifling ajtyiiints.' . .■ ; ; f | {yi C^**yQ Tmuch,V then; for the principal producing countries. When we turn our attention #o the countries and peoples who consume this enormous quantity of beverage-making material, we find that heading the list as the greatest tea importers of the world are the people of the United Kingdom. During the last few years the annual import of tea from all sources into this country has averaged no less than 255,1 12,000 lbs., costing us £8,683,000 ! We are followed by Russia, which annually receives about 126,000,000 lbs., the United States with 81,389,000 lbs., followed by Holland, Australia, Canada, Germany and New Zealand with much smaller amounts. To us, as English people, a most important question in connection with the world's tea' industry is, to what extent is the British-grown article displacing from the world's market the product of our only serious rival, China ? Let us consider, the state of affairs in some of the chief consuming countries. In the United States and -Canada the taste for British- grown teas appears to have taken a firm hold. The quantity sent direct from Calcutta to Canada in 1904 was thirty-five per cent, higher than in 1903. Further, black teas from China have practically disappeared from the Canadian market, and in all probability the green -teas from Japan, which at present are very popular in America, will follow them in a few years'; for since Ceylon green tea was introduced in 1899 the imports from Japan have decreased from eleven to four million pounds. • "? • • JAPANESE WOMEN PLUCKING TEA 150 The World's Commercial Products The United States takes half as much again Indian tea as it did a year or so ago, and the increase in popularity of the beverage among our cousins gives hope to the Eastern planters of the creation of a new market of the greatest value. Australia, like the rest of the world, is changing her taste in tea. Formerly her supplies were largely obtained from China, but the imports from, that country are steadily diminishing. Although considerable quantities of -tea are now taken from Java, the real fight for the Australian market lies between Ceylon and India. At the present time the advantage lies with Ceylon, whose exports to the Southern Empire have increased during the last ten years from ten to twenty-four million pounds. Great efforts; attended with considerable success, are being made to develop the Asiatic trade in British-grown tea, and Persia is now theJourth largest consumer of the Indian pro- duct. The .preparation of brick tea for Tibet is also receiving much attention at the hands of Indian planters, who have voluntarily submitted to a self-imposed tax to be devoted to pushing their production among the Tibetans. Austria, Belgium, Sweden, Holland, Turkey, France, and Russia are all advancing in their tea imports. Much of the tea taken by Holland naturally comes from their colony of Java, but the increase in the Russian import nearly all comes from British sources, to the loss of the Chinese merchant. AlthonglwHie of the most striking facts in connection with the tea export trade is the practical loss, to China of some of the most important of the world's markets, it must not be supposed that the tea industry in China is ruined. As a matter of fact, the area under cultivation has not diminished to any appreciable extent during the past forty years ; for the Chinese grower has a vast local market, and immense quantities of inferior tea are converted into the " brick tea " for Tibet and Russia. Moreover, at the present time, there are un- mistakable signs that the Chinese intend to make a bold bid for the recovery of some of the ground they have lost; for the more enlightened among them have realised that the trade was lost owing to inferior, and to the West- ern mind sometimes repulsive, methods of manufacture, and also to the fact that, generally speaking, hand labour must—at last give way before machinery. That the Chinese are serious in their desire to regain their trade is evidenced by the fact that in 1905 the Viceroy of Nanking appointed a Chinese Tea Commission, headed by an Englishman, Mr. Lyall, to enquire into the methods and conditions of tea cultivation and manufacture in India and Ceylon. As a whole the Chinese soil is said to be less productive with regard to tea than that of our Eastern Empire, and the climate of the tea districts is colder and less forcing ; further, the yield per acre cannot com- pare with that obtained by the European planters. Nevertheless, the ruling classes in China have" become alarmed at the great falling off in revenue due to the diminution of the export trade, for there are heavy Chinese transit and export duties on the product, and it is their intention to see what improved methods of cultivation and manufacture can do to restore this Chinese method of rolling the leaf Tea 151 CHESTS OF CHINESE TEA READY FOR SHIPMENT trade. Whether the Chinese peasant can be induced to depart from the methods and customs which have been handed down to him for countless generations is a matter open to question, but the attempt on the part of the authorities is significant, and the situation may be very accurately summed up in the words of an editorial of a Ceylon planting paper : "... The way in which it (i.e., the Chinese trade) has steadily gone back during the last fifty years is not at all conclusive proof that there can be no important recovery, under changed conditions I and methods. In other words, the swing of the pendulum may be witnessed in this department of agriculture and commerce as well as in any other, seeing that the (Chinese) tea- - gardens have suffered no radical injury." When we examine the figures showing the amount of tea annually consumed per head of the population we find that although it is a British country which heads the list, the tea- drinkers of Great Britain must give way to their sons and daughters of Australasia, who use no less than 71 lbs. per person every year. In the United Kingdom the amount is about a pound less, viz., 6"03 lbs. per head, and then we have Canada (4 lbs.), Holland (14 lb.), United States (T30 lb.), Russia (1*25 lb:), Norway (TlOlb.), Denmark (0-36 lb.), Germany (0'131b.), and France (0"061b.). The large consumption in the British Empire is very striking, though not unexpectedly so ; but to the average Englishman the most surprising feature of these figures is the relatively small amount consumed per head of the population of Russia. In this country the Russians are commonly regarded as a great tea-drinking people, but this is a popular error, for only the comparatively wealthy classes in Russia can afford to buy tea, which is quite beyond the reach of the poor peasants who form the great bulk of the population. The rise in popularity of tea in England was comparatively slow up to the beginning of the nineteenth century. In 1711 the consumption per head was only 0"03 lb., and in 1780 it had risen to only 0"57 lb. During the first four decades of the next century the average stood at about 1*25 lb., but after 1840, the period at which tea-planting was rapidly being extended in India, the consumption rose very quickly. In spite of the increasing consumption, however, tea has continued to fall in price owing to the enormous increase in production. With regard to the chemistry, of tea, the most important constituents from the point of view of the quality of the beverage are an essential oil, tannin, and an alkaloid known as theine. The flavour of the tea is largely due to the essential oil, but the remarkable stimulating and refreshing^qualities of the beverage are due to the theine which is-also-found in coffee, Paraguay r drying-house, which may indeed be the cottage itself. The fire is then kindled in the furnace Tea 153 increases with their it becomes hands so that all impossible to mix and a quantity of leaves thrown into the heated pans and constantly turned over and kept in motion by men and women stationed in front of the pans. The heat immediately •causes the leaves to crack and become quite moist with the sap which is given out under its influence, and in about five minutes the process is complete, the leaves having become quite .soft, pliable, and altogether devoid of their original crispness. The leaves are then taken from the pans and placed upon bamboo tables, around which stand several persons, who take a quantity of the leaves in their hands and carefully roll them on the table in a manner •closely resembling the working and kneading of ordinary baker's dough. The object of this process, which lasts about five or six minutes, is to twist the leaves and, .at the same time, to express the sap and moisture, which escapes through the interstices of the surface of the table. In the next stage of the process the object is to expel the moisture as gradually and .gently as possible, retaining the softness and elasticity of the leaves to the fullest extent. This is effected by taking the rolled leaves, spreading them out thinly and evenly upon a screen made of strips of the ever-useful bamboo, and exposing them to the action of the atmosphere. *v There can be no fixed time for the completion of this process, which depends entirely upon the state of the weather, but experience has taught the operators to avoid placing the leaves in the direct rays of a powerful sun, which evaporates the moisture too rapidly, leaving the leaves crisp, coarse, and quite unfit for the next stage in the manufacture. -The soft and pliant leaves are now again thrown into the drying-pans, and subjected to the action •of a slow, steady fire. It is of great importance that the leaves should not be scorched or burned, and it is the custom for one person to attend solely to the fire while others, standing in front of the pans, mix and agitate the leaves .shall be equally dried. As the temperature the leaves by hand,' so small bamboo whisks or brushes are employed, the. leaves being thrown up against the sloping sides of the pans and allowed to roll back into the iron portion at the bottom. The leaves gradually part with their moisture, twist and curl, and after about an hour, are taken from the pans, to constitute the fin- ished product. Tea so pre- pared is green in colour, but it lacks the vividness of •colour which characterises much of the green teas ■exported to Europe and America, and which, in former days, at any rate, was produced at Canton by dyeing the leaves with gypsum and Prussian blue. It is a significant statement •of Chinese travellers that the Chinese themselves never use the artificially coloured teas ! TEA CARAVAN IN THE STREETS OF PEKIN 154 The World's Commercial Products JAPANESE WOMEN ROASTING THE TEA When the tea finally leaves the drying-pans it is picked over and sifted, and finally sorted into different grades previous to packing. If the tea is intended for export, this is a very important process, since the value of a consignment largely depends upon the "evenness" of the leaf, and considerable experience and manual dexterity are necessary to ensure the tea being of the same grade and quality throughout. Once satisfactorily sorted, the tea is put into boxes or baskets and pressed down by men treading it with their feet, which are covered with clean cloth or straw shoes put on for the purpose. • • - • Up to the end of the rolling process, the preparation of black teas proceeds upon lines exactly similar to those described above, but after the rolling, the leaves are subjected to a much more extended drying process in the open air, the period lasting for two or three days. The differ- ence in the colour and character of the teas almost entirely depends upon the differences in the methods of preparation at this stage, and, since the matter is more fully dealt with below in connection with the Ceylon and Indian industry, it will be sufficient to add that the leaves intended to produce black tea, during this extended exposure to the atmosphere, undergo a process of fermentation which does not obtain in the manufacture of green teasJ Great care is taken in the final drying or " firing " of the black teas, an experienced and generally old man being invariably employed to regulate the furnace while the other members of the family keep the leaves constantly agitated in the pans. The finished tea is then sorted and packed as in the case of the green varieties. The teas, whether green or black, have next to be sold, and at the end of the season,- the great tea merchants or their agents visit the tea districts, taking with them large supplies of copper coin with which to pay for the commodity. The merchants generally put up at the local inn, and as soon as they have arrived* the growers bring in their baskets of tea, slung, on -bamboo poles, to submit them to the inspection of the prospective buyer. If the quality is satisfactory the bargain is struck and the tea and money change hands. Should the tea not meet with the approval of the merchant, it is promptly taken away and offered in 155 156 The World's Commercial Products AN INDIAN TEA NURSERY other quarters until a sale is effected. The teas bought up in a district are then con- veyed to the most convenient town, where they are again graded and packed into chests for the foreign markets. The purest of all teas, which is least touched by the human hand in its manu- facture, is the Virgin Tea of China. It is prepared exclu- sively from the very youngest leaves of the shrub and is used principally at Chinese mar- riages, and so delicate are the leaves that even after pro- longed, boiling but little tan- nin is evident. The leaves are tied together with silk thread in tiny bundles, and when the tea is to be brewed a bundle of the leaves is held in a large clear crystal cup of very thin glass by means of a small ivory or- silver skewer, and the boiling water poured in. The leaves slowly unfold and, changing colour from the dingy greyish-black condition, quickly revert to nearly the same refreshing greenness which they possessed when they were plucked. The infusion, as seen through-the glass, is of a pale amber colour, resembling that of the finest •qualities of cognac ; it is drunk directly from the leaves, the aroma and odour being obtained to perfection. • • The Chinese are experts in the adulteration of tea. They use for this purpose the leaves of the rose, ash, and plum, rhododendron, buckthorn, and many other plants. The teas are also -scented with the flowers of an olive (Olea fragrans), Chloranthus inconspicuus, and species •of Gardenia and Jasminum. Even mineral adulterants are also employed to give weight ft was largely owing to the j ealousy of the Chinese Government in preventing the visits of foreigners to tfye great tea-growing districts, that the mystery surrounding the origin of " black" and " green " teas was not finally cleared up until nearly the middle of last century. Up to that time we find English writers contradicting one another, some asserting that the black and green teas were produced from the same variety of the tea plant, the differences in the finished product being due entirely to differences in the process of manufacture, and others •equally convinced that the two kinds of tea were produced from distinct varieties of the tea plant, the " black " teas being prepared from the leaves of Thea Bohea and the " green " teas from Thea viridis, both plants being well known in England. During the early part of the nineteenth century, however, the great botanist, Robert Fortune, was travelling in China •on behalf of the Horticultural Society, and it was due to the efforts of this observer that the mystery was at last explained. The tea-growing districts visited by Fortune were those of Canton, Fokien, and Chekiang. Up to the time of his investigations upon the matter, Fortune had held to the view of the dual origin of the two varieties of tea, and was gratified to find that, while in Canton black tea was obtained from a plant which he identified as the true Thea Bohea, in the green-tea districts of the province of Chekiang he failed to meet with a single plant of this species, and further, all the green-tea plants he was able to examine in the Ning-po country and in the islands of the Chusan Archipelago, proved to be, without exception, Tea 157 hea viridis. • Fortune then left for the province of Fokien, fully convinced that he would nd the tea hills covered with Thea Bohea, since black tea was largely produced in the district", nd the species took its name from the Bohee hills in this province. In his book, " Wanderings in China," Fortune proceeds : " Great was my surprise to find all the tea plants on the tea hills near Foo-chow exactly the same as those in the green-tea districts of the north. , Here were then green-tea plantations on black-tea hills, and not a single plant of the Thea Bohea to' be seen. Moreover, at the time of my visit, the natives were busily employed in the manufacture f black teas. Although the specific differences of the tea-plants were well known to me*. TRANSPLANTING YOUNG TEA PLANTS I was so much surprised, and I may add amused, at this discovery, that I procured a set of specimens for the herbarium, and also dug up a living plant, which I took northward to- Chekiang. On comparing it with those which grow on the green-tea hills, no difference what- ever was observed. It appears, therefore, that the black and green teas of the northern districts of China (those districts in which the greatest part of the teas for the foreign markets are made) are both produced from the same variety, and that that variety is the Thea viridis, or what is commonly called the green-tea plant. On the other hand, those black and green teas which are manufactured in considerable quantities in the vicinity of Canton are obtained from the Thea Bohea, or black tea. And, really, when we give the subject our unprejudiced considera- tion, there seems nothing surprising in this state of things. Moreover, we must bear in mind that our former opinions were formed upon statements made to us by the Chinese at Canton, who will say anything which suits their purpose, and rarely give themselves any trouble- OF THE UNIVERSITY 158 The World's Commercial Products PRUNING TEA IN CEYLON to ascertain whether the information they communicate be true or false." It was thus defi- nitely proved that the differences in the teas reaching this country were not due to specific •differences in the tea plants, but were produced as a result of differences in methods of manufacture. TEA IN JAPAN The success which has attended the efforts of Indian and Ceylon planters to oust China teas-from some of the most important of the world's markets is one of the most striking facts in the history of the tea trade. Up to the present, however, the British planter has made comparatively little impression upon the volume of the Japanese export trade in tea, and in the United States and Canada the product of Japan holds a position which appears to be very secure, while certain grades have earned a reputation which cannot readily be shaken. Within recent years considerable attention has been paid by British growers to the Japanese tea industry, and several reports have been issued as a result of investigations carried out on the spot. Japanese teas may be divided into four classes : (1) Hikacha or Yencha, a powdered tea of high quality used only on ceremonial occasions ; (2) Green tea, subdivided / into Gyokuro (" pearly dew "), and Sencha, the latter being inferior to Gyokuro in quality, \ but constituting the bulk of the tea drunk by the people ; (3) Bancha, consisting of the pre- vious war's Leaves mixed with withered stalks and chopped twigs; (4) Oolong and Black tea.,- With regard to the Black teas j it is interesting to note, that comparatively little is produced in Japan,, since for some, reason not sufficiently understood, but probably due to imperfect methods, the native leaf does not undergo the fermentation processes successfully, and poor results generally attend the efforts made to obtain a good black tea. The Oolong varieties have the colour and appearance of black tea but possess the flavour of green tea. Japan proper produces, very little Oolong, but large quantities are shipped from Formosa. The teas most interesting to the British planter, however, are the Gyokuro and Sencha green teas, for these are the grades exported to the American continent, where green teas have a great hold upon the popular, taste. They further form the bulk of tea consumed by he Japanese themselves. , e Japanese tea-planter prefers the lower slopes of the hills for setting out his bushes, although, providing that the drainage is satisfactory, successful plantations can be laid Tea 159 out on the level plains. The famous -Uji tea gardens are mostly on the plains. It fre- quently happens that the tea is interplanted with other crops, mulberries and plums being often. grown between the tea bushes, while in one district pears are grown on trellises placed above the tea. The bushes are usually allowed to reach a height of about three- feet, but in the Uji gardens they frequently attain to six feet. A peculiarity of the Uji district is that a large part of the tea is cultivated under artificial shade, the effect being to produce a better quality of leaf of a darker green colour. Bamboo poles are set up at intervals and arranged to support horizontal mats also made of bamboo. After the crop has been plucked the matting and poles are taken down. This shade-grown tea is highly valued by the Japanese, and it is grown exclusively for home consumption. Picking .-usually begins at the end of the third or fourth year and the best leaf is obtained from the eighth to the fifteenth year. The ordinary life of the bush is about twenty-five -years. There are, as a rule, two crops in the year, one in May and the second in the middle of June, after the rains ; a third, crop is sometimes obtained, but the quality of the leaf is very poor. The bushes are pruned after the first. crop, and again during the winter. "• In the manufacture of the teas it is interesting to note that in the case of the better-class green, teas, and a considerable proportion of Sencha, no machinery is used, the whole process being carried out by hand, the popular belief being that it is impossible to procure with machinery the delicate aroma produced by the old-fashioned hand methods. For the production of teas destined for the export trade, however, machinery has entirely supplanted hand labour. The preparation of the leaves begins as soon as possible after picking, and in the case of Sencha, which forms the bulk of the tea consumed in Japan, the first process is said to be that of steaming. The steam is allowed to act on the leaves for about four minutes, when they are shaken by hand, and spread out on mats to dry. The important procsss of firing now A KANGANI SUPERINTENDING THE PLUCKING 160 The World's Commercial Products follows. The workman first smears the surface of the paper lining of the firing tray with rice paste, which, when dry, affords a hard polished surface. A small quantity of the steamed leaf is then poured into the tray, which the workman turns over repeatedly until the edges of the leaves begin to curl as a result of the heat and mechanical friction. The workman then works the leaf into balls, which he breaks and again works up, extracting, mean- while, the stalks, dried leaf, and other impurities. As the firing progresses, the fresh green colour of the leaves gradually changes to an olive brown, and the fragrant odour of the tea becomes perceptible. The mass gradually shrinks in size as the moisture evapo- rates, and when finally pro- nounced to be dry — the whole operation of firing lasts about three hours — it is seen that each leaf is separately twisted and rolled. The tea is then spread out on paper-lined trays similar to those used for firing, and left until the leaves become quite brittle. If destined for home consump- tion the leaves are sifted with bamboo hand sieves of three or, four degrees of fineness, and any impurities remaining are removed by hand ; if for export, the sifting is not carried out, but the tea is immediately packed in cases made of thick cartridge paper and despatched to the wholesale merchant. , The methods of cultiva- tion and processes of manu- facture adopted in the case of Gyokuro and Hikacha teas — the finest qualities— are said to differ in several respects- from those described above for the bulk of the tea raised in Japan ; but the actual details- are not perfectly known. TEA IN CEYLON The story of the rise of the tea industry in Ceylon is one of the most interesting in the history of planting. Up to the middle of the last century, coffee had been the most WEIGHING THE DAY'S PLUCKING TEA PLANT Reproduced by permission of Messrs. Cooper & Cooper Tea 161 important of the European cultivations, but in the sixties a terrible fungal disease commenced its ravages in the coffee plantations of the island, and after a comparatively few years it was evident that the industry was doomed. The enormous losses, widespread consternation, and distress occasioned by this calamity will be referred to in the article dealing with coffee, and need be no more than mentioned here ; but in spite of the blow which had been dealt them, the planters with commendable pluck and energy turned all their attention to the discovery of other crops suitable to the climate and conditions of Ceylon, with which their broken fortunes might be restored. Attention was given to cinchona, cardamoms, cacao, and other crops without any great measure of success ; but it was not until they seriously turned their attention to tea that the panacea was discovered. It was found that the warm, TEA PLANTATIONS NEAR BATOUM damp climate of many parts of the island was pre-eminently suited to the cultivation of the new crop ; moreover the hardiness of the tea-plant when compared with coffee soon raised the hopes of the planters and encouraged them in their new efforts. ,. It has been frequently stated that tea was found to be already existing in Ceylon by the Dutch, who occupied the island before the advent of the British ; but this statement lacks any really satisfactory confirmation. A very small amount of tea was originally planted out in Ceylon as early as 1839; but the first regular plantation was not opened out until 1867, when Messrs. Keir, Dundas & Co. started to raise tea at Yoolcondura. The area was about ten acres, and for some few years the industry made no great strides : in 1877 some 2,720 acres were under tea, which ten years later had increased to 170,000 acres. In 1897 the area had grown to 350,000 acres, and last year (1905) the official returns showed an area of 390,000 acres. The area recorded for 1905 includes a certain acreage which has been interplanted with rubber, and in Ferguson's Ceylon Handbook it is estimated that the actual area under tea last year was about 380,000 acres. One of the most noticeable facts borne out by a study of Ceylon tea statistics is that whereas during the period up to 1890 the acreage had increased by leaps and bounds, during the last ten years or so the area planted has been practically 162 The World's Commercial Products H THE TEA HARVEST AT BATOUM stationary, and it is the opinion of those best able to judge that, for the present at any rate, the growth of the tea industry has reached its upper limit. The average size of an estate in Ceylon is about 300 acres. As in so many industries in all parts of the world, there has been a tendency of late years to group several estates under one working staff to effect economies in working and management expenses, but, nevertheless, by far the greatest proportion of estates are small, and in the hands of the European planters resident on the estates themselves. In a very large number of cases, perhaps in the majority, the estates are owned by companies and the planters are servants of the company, and not the actual owners of the estates, as was more often the case in former years. VThe enormous labour supply necessary for the Ceylon plantations is recruited principally from among the Tamils of Southern India, who have proved themselves to be, on the whole, very satisfactory labourers. The people — men, women, and children — are recruited from their villages by their future overseers, who are locally known as " Kanganies," and while the majority return to their homes with accumulated savings, some elect to settle down in Ceylon for life. The approximate number of coolies employed is about 400,000. / By far the greater part of Ceylon tea is exported to the United Kingdom. Next to ' England, the> most important customer is Australia, followed by Russia and AmericaL At the present time, special attention is being paid to the production of green teas, the object in view being to foster the American market. The total exports from Ceylon in 1905 were approximately 160,000,000 lbs. TEA IN INDIA The first practical suggestion for the establishment of tea plantations in India was made in 1788 by Sir Joseph Banks to the East India Company; but his suggestions were not acted upon until 1833, when experimental plantations were laid out in the Tea 163 district of Kumaon, in the Himalayas — the seeds and plants used being imported from China. No sooner had the experiments been initiated than attention was drawn to the statement that a tea plant indigenous to Assam had been discovered some years before, and that this variety was probably more suited to cultivation than the Chinese plant. The announcement was received with a certain amount of scepticism on the part of experts, but a travelling commission was sent to Assam to settle the matter. Although an undoubted tea plant, now known as Thea assamica, was found to occur abundantly, it was regarded as a degenerate form of the Chinese variety; the committee therefore recommended the further cultivation of plants from China. In 1837 and the years imme- diately following, discoveries .of extensive tracts of country in Assam bearing the indigenous tea were made, and in 1838 the first consignment of Indian tea^ consisting of 488 lbs., was sent to London, the price obtained being 9s. 5d. per lb. About this time the principal planta- tions came under the control of the famous Assam Company, and by 1854 the Indian export had risen to a quarter of a million pounds. Planting was then started in Cachar and Sylhet, and in 1858-9 the plantations of Darjeeling were commenced. Since that time the industry has made enormous strides, and several other districts have imitated the example of Assam and planted out large areas in tea. At the present day the tea districts of India.are Eastern Bengal and Assam, with 422,335 acres ; Bengal (Darjeeling and Chota Nagpur), with 53,024 acres ; Northern India (United Provinces and Punjab), with 17,346 acres ; Southern India (Madras and Travancore), with 38,789 acres : a grandjtotal of 531,494 acres, with-a total pro- duction last year of 221,068,000 lbs. ! In 1875 the total production was about 26^- million pounds. Of the total export in 1905 the United Kingdom took no less than 166,754,000 lbs., or, roughly speaking, seventy-six per cent. The next best customers were Canada, taking 15,018,000 lbs., followed by Russia with nearly 10,000,000 lbs., and Australia with over/ 7,000,000 lbs. Other important buyers were Asiatic Turkey, the United States, Ceylon, Persia^ China, and Kashmir. TEA IN NATAL Next to Ceylon and India, Natal is by far the most important of the tea-producing colonies of the British Empire, and the industry is one of considerable value to the country. From 7 !/- V )h V V y TEA FACTORY AT BATOUM 164 The World's Commercial Products the most reliable records it would appear that_the tea plant was first introduced into Natal about 1850, from that " clearing-house of the botanical world" — Kew. The most import- ant, fact was that the plants flourished in their new home. Tea-growing as a definite industry, however, was not seriously undertaken until about a quarter of a century later. It will be remembered that the destruction of the coffee plantations by a fungoid disease was essentially the cause of the existence of the now splendid Ceylon tea industry, and it was precisely the same misfortune which in 1877-78 necessitated Natal planters seeking a new field for the investment of their capital. When it became evident that coffee was doomed as a cultivation of first-class importance, Mr. (now Sir) J. L. Hulett became convinced that, with suitable plants, tea would prove the salvation of the planters. The WEIGHING THE DAYS PLUCKING IN CEYLON matter was brought before the Lower Tugela Planters' Association, and on the Government being asked to render assistance, free freight on seed imported from India was offered to the colonists. The latter formed a syndicate to defray expenses, and seed from Calcutta was landed in Natal in March, 1877, and immediately planted out in nurseries. Unfortunately, about the time the seedlings were planted out a severe drought visited the country, and out of 4,000 plants successfully raised from the seed only 1,200 survived. The seriousness of this set back was in- creased by the fact that the surviving plants would require three or four years before they would yield any seed for nursery purposes, and it was not until 1880 that seed was gathered from them, the quantity obtained being barely sufficient to plant five acres. In the following year, however, the planters returned to their task with undiminished determination, and, in spite of many subsequent discouragements, the acreage gradually increased until at the present time it extends to over 4,000 acres. The greater part of this area is in the Lower Tugela Division of the country of Victoria, and tea is also grown to a small extent in the Alexandra Division. The most productive tea gardens are at an elevation of about 1,000 feet, the land at this altitude being generally of -an undulating character, well watered, and the climate sufficiently humid to encourage leaf -production. The plucking season commences in September and lasts until June of the following year, during which period each bush is picked about sixteen times. 165 166 The World's Commercial Products A ROLLING MACHINE AT WORK Undoubtedly the most hopeful outlook for the Natal tea industry lies in capturing the South African market ; for, while the annual import of tea into South Africa is considerably over 6,000,000 lbs., the annual production of the commodity in Natal does not exceed more than 2,000,000 lbs. In order to satisfy the local demand it would be necessary to increase the present acreage three-fold, i.e., to about 13,000 acres. TEA IN THE CAUCASUS For several years past serious efforts have been made by the Russian Government and by private individuals to establish a tea industry in the neighbourhood of Batoum, in the Caucasus. The Imperial plantations are situated at Chackra, and have an area of about 400 acres, and in 1905 the tea prepared from a plucking of 102 acres reached a total of 21,600 lbs. The Popoff plantations, which are owned by a private firm, are somewhat smaller in area, and are situated at Chackra, Salibauri, and Kaprshun. Up to the present, however, comparatively little progress has been made in the industry, the labour question being one of great difficulty. OTHER TEA-GROWING COUNTRIES A small tea industry alsoexists in Jamaica. In 1868 an acre of land was planted with tea by the Government, and, as the experiment met with some considerable success, the area was later increased. In 1887 there was one private tea-garden in the island at Portland Gap, about twelve miles from Kingston, with twelve acres under cultivation. Nine years later Tea 167 further experiments were made at Ramble in St. Ann, and the results being successful, the cultivation has gradually increased until, at the present day, there are about ninety acres under the crop. In Fiji an experiment in tea planting was made in 1880. The island chosen was Tayiuni, and an area of thirty acres was planted out with the Assam hybrid ; the area was gradually extended to several hundred acres, when it became known as the Alpha Tea Estate. The success of this garden — situated within four miles from the coast and at an altitude of 1 ,000 feet — led to the establishment of another plantation in the neighbouring island of Vanua Levu, known as the Masusa Estate. Fiji tea is chiefly consumed locally. Tea is also cultivated in the State of Johore, in the Straits Settlements, and small planta- tions exist in Burma, the Andamans, and Tonquin. Experiments have also been made in British Central Africa. In Java a valuable export trade is being gradually built up. The iirst seed was introduced into Java from Japan in 1827 by von Siebold, and young plants were raised in the famous botanical garden at Buitenzorg,' but a few years later better varieties were obtained from China by Jacobsen, who may be regarded as the founder of the tea industry in Java. MODERN METHODS OF CULTIVATION AND MANUFACTURE We will now turn our attention to the cultivation and manufacture of tea as practised by the European planters of Ceylon and India. In opening out a new tea garden the first step is the establishment of a nursery for raising the young plants which are to fill the garden. A piece of jungle near the new plantation is cleared ; then the soil carefully hoed, and prepared for the seed. The land is now divided into beds between which are shallow trenches, and when the soil is sufficiently prepared, the seed, which has been allowed to sprout in seed beds, is planted out and the ground covered with thatching to prevent scorching by the sun. The nursery is carefully fenced in to prevent damage by cattle and wild animals. The seed is obtained from plants grown in a special " seed garden " where the bushes are not pruned in ordinary cultivation, but allowed to attain their full growth. Meanwhile the clearing of the future garden has been proceeding, and, when complete, the soil is carefully hoed and then marked out with stakes, about four feet apart, indicating the lines or rows which are to receive the young tea-plants from the nursery. The roads and drains of the plantation are dug by the coolies, and then transplanting commen- ces. The young plants are taken from the nurseries when about twelve inches high, and planted in the holes prepared for them, care being taken to keep the wall of earth round the roots of the seedling intact. The plants become well established and ready for picking when three years old, at which time they are send- ing out abundance of young leaf-shoots, known as the end view of/.a rolling machine 168 The World's Commercial Products " flush." From this time onwards the picking or plucking is carried out at regular inter- vals, and, to induce the formation of abundant flushes, the bushes are pruned from time to time, a process which also keeps the growth of the plant within bounds to allow of the pluck- ing being conveniently performed. In the colder climates of China and Japan, the flushing ceases in the winter ; but in Ceylon it goes on all the year round. In Ceylon the flush is ready for picking every ten or twelve days. The process consists in plucking the young shoots, to include the third or fourth leaf from the bud, and upon the size of the leaf depends the quality of the tea manufacture. Thus, plucking is designated as " fine " when the bud at the top of the shoot and the two young leaves just below it are taken, " medium " when the bud and three, " coarse " when the bud and four leaves are taken. From the " fine " plucking the tea known as " pekoes " are made, " flowery pekoe " being derived from the youngest leaf, " orange pekoe " from the next youngest, and " pekoe " from the third leaf ; " souchongs " and " congous " are prepared from the larger leaves. Pekoe-souchong, as the name indicates, is intermediate in quality between pekoe and souchong. The flush is gathered by the women into baskets and when the latter are full they are taken to the factory to be weighed. The leaf is carried to the upper floor of the factory, where it is thinly spread out on light open-work shelves of canvas, or on wire-meshed trays placed one above the other, in order that the drying or "withering" of the leaf may take place. In good weather the correct degree of flaccidity is reached in seventeen or eighteen hours; but if the weather is damp, artificial heat is employed. The withered leaf is then collected from the trays and thrown down through shoots into the rolling machines, A SIROCCO FIRING MACHINE 169 170 The World's Commercial Products FERMENTING THE LEAF which are generally situated on the ground floor. The object of the rolling process is, firstly, to bruise the leaves so as to allow the leaf juices to become mixed, and, secondly, to impart a twist or curl to the leaf. The rolling machines consist essentially of a table with a central depression to hold the leaf and a hopper above it, the two moving one over the other with an eccentric motion. Any required degree of pressure can be put upon the mass of leaf that is being rolled, and at the end of about an hour the door in the bottom of the machine opens and the roll falls out, the twisted leaves, which have become somewhat yellowish, clinging together in masses which are broken up in a machine known as a " roll breaker " ; a " sifter," which separates the coarser leaf from the finer, is usually attached to the breaker. The next process, the fermentation process, is one of the most important in tea manufacture; for on its efficient accomplishment depends to a large extent the quality and character of the tea. Fur- ther, the omission after this stage in the manufacture results in the formation of " green " teas, which formerly enjoyed' great popularity. In the preparation of black teas, then, the rolled leaf is piled in drawers one above the other or on mats, and then left to ferment or oxidise, air being allowed free access. The process occupies a varying length of time according to the particular garden and the condition of the weather. During the fermentation the leaf emits a peculiar odour and changes colour, and after about two hours, when the right degree of copper-brown colour has been attained, the leaf is " fired " in the drying machines, the heat arresting all further fermentation. In many factories the leafjjis re-rolled previous to firing. Besides the checking of the fermentation, the object of the Tea 171 firing process is to remove all the moisture without driving off the essential oil and other constituents, upon which the value of the manufactured article largely depends. The firing is ■effected by one or more of many types of machines, all of which act by passing a current of hot, dry air through the damp fermented leaf until it is dry and brittle. A commonly used type of machine is the " Sirocco," to the illustration of which the reader is referred. The tea is then taken to the sorting room, where it is sifted into grades by a machine con- sisting of a series of moving sieves of different sizes of mesh. The resulting sittings are classed as Flowery Orange Pekoe, Orange Pekoe, and Pekoe No. 1, and are known as " unbroken teas." The first mentioned is the least coarse and finest tea, but the coarser tea which does not sift through the meshes is transferred to " breaking machines," and broken up and again sifted, the products being known as Broken Orange Pekoe, Pekoe No. 2, etc. The tea dust which accumulates during these processes is kept separate from the better qualities, and is shipped as " dust " and " tannings." The processes in the manufacture of green tea in India and Ceylon are similar in most respects to those employed for black tea. The various grades resulting from the sifting receive names different from those applied to black teas, the principal varieties in descending order of quality being Young Hyson, Hyson No. 1, Hyson No. 2, Gunpowder, and Dust. The tea is then packed into lead-lined chests, stamped with the name of the garden or factory, and transported to the quay at Colombo, Calcutta, or Chittagong, whence it is shipped to England. r \ BRICK TEA y )■' —I A most interesting variety of tea is that so extensively used in Tibet and some parts of Russia, and known as " Brick Tea." The product may be briefly described as very cheap and coarse teas which, with the small twigs, have been compressed into blocks. The chief •centre of the industry is at Ssu-chuan, in Western China, and it has been estimated that the Tibetans annually import the tea to the extent of from twenty to thirty million pounds. Very little care is exercised in the plucking process. The main object of the cultivator is to obtain a good weight of the product with as little trouble as possible, and hence the first six or seven leaves are roughly stripped from the twigs or, as is more generally the case, the twigs, to a length of perhaps twelve inches, are literally reaped from the plant. There is no withering or regular fermentation pro- cess ; the twigs and leaves are at once heated in thin iron pans for a few minutes, and then tied up into bun- dles and sacks and taken away to the factories or "hongs," where the material is piled in heaps and allowed to ferment. After being •dried in the sun, the tea is sorted into grades, when it is steamed and finally pressed into a shallow brick- shaped mould by means of a heavy rammer ; it is often necessary to mix the chopped twigs with a paste made from glutinous rice in order to make them adhesive. In sifting the tea with sieves 172 The World's Commercial Products three or four days the bricks have become quite hard, and, after being stamped with the- maker's name or device, are wrapped in paper and made into strong packages for transport to- Tibet. Large quantities — some 20,000 tons per annum — of a brick tea are made at Hankow, and the same town also manufactures " Tablet Tea," both for the Russian market. The bricks are very different from the Tibetan article, for they are manufactured from tea dust of good quality, the dust being either purchased as such by the factories (which are under Russian control), or else tea is bought and ground to powder by machinery. The tea dust is carefully sifted into grades and steamed for a few minutes, after which it is cast into bricks, in separate moulds, by hydraulic pressure. The bricks are allowed to dry in the moulds for two COOLIES CARRYING BRICK TEA TO TIBET The Tablet Tea is or three weeks, when they are packed in bamboo baskets for transport, prepared from the finer grades of tea destined for European Russia. OTHER "TEAS" The famous Paraguay Tea, or Yerba de Mate, is one of the most important economic products of South America. The tea is derived principally from the leaves of Ilex paraguariensis, although an investigation carried out at Kew a few years since showed that several varieties of this species were concerned in the product, and that it was probable that other species of the same genus were also used as a source of the tea. Further, there was evidence to show that, in addition, the leaves of Symplocos lanceolata and Elaeodendron quadrangulatum, plants belonging to quite different families, were also used for the same purpose. By far the greater bulk of mate, however, is prepared from Ilex paraguariensis. The Tea 173 plant is a shrub belonging to the natural order, Aquifoliaceae (Holly family), and bears oval leaves about four or five inches long, with serrated edges. It is found commonly in Brazil and Paraguay, where there are also regular plantations ; but the leaves are extensively used through- out South America, and several million pounds of the prepared mate are annually exported from the latter country to various parts of the continent ; small quantities are also sent to Europe. In the preparation of mate the leaves are not plucked from the plant as in the case of ordinary tea ; but large leafy branches are cut from the shrub and placed on hurdles over a wood fire until sufficiently roasted. The dried branches are then placed on a hard floor, .and the withered leaves beaten with sticks, after which they are reduced to a coarse powder TRANSPORT OF TEA IN CEYLON in rude mills. The product is then ready for packing in skins and leather bags. There are said to be three principal grades of mate in the South American market, viz., Caa-Cuys, which is Ihe half-expanded leaf-buds ; Caa-Miri, the unroasted leaf from which the principal veins have been removed ; and Caa-Guaza, or Yerba de Palos of the Spaniards, which is prepared from the roasted leaves together with the leaf stalks and smaller twigs. The infusion is prepared for drinking by putting a small quantity of the tea in a cup with a little sugar ; a drinking-tube •or bombilla, with a wire network or perforations at the bottom, is then placed in the cup and boiling water poured in the mate. When sufficiently cool, the infusion is sucked up through the tube. Mate has an agreeable, slightly aromatic odour, and a somewhat bitter taste. It is very refreshing, and is a valuable restorative, especially after great physical exertion, while it also possesses mild diuretic and aperient properties. Another species of Ilex (I. cassine) was the source of the famous " black drink " of the North American Indians, which is known under the name of " Youpon." The home of .the plant is along the eastern and southern shores of the United States, and it is not found 174 The World's Commercial Products to any great distance inland. It is an elegant shrub ten to fifteen feet high ; but sometimes rises into a small tree of twenty to twenty-five feet. The oval, toothed leaves, which are about an inch long and very smooth, were once extensively used by the natives of North America as tea, the preparation of the beverage being very similar to that of ordinary tea. The method of preparing cassine was comparatively simple. The leaves and tender young branches were carefully picked, the season chosen being the time of harvest. The leaves were dried in the sun or shade and afterwards roasted in ovens, remains of which are still found in the Cherokee region. The roasted leaves were kept in baskets in a dry place until needed for use. An infusion of cassine leaves with boiling water gives, after cooling, a liquor of little taste and slight odour. But, if boiled for an hour, the infusion becomes a very dark liquid, resembling strong black tea of an odour not unlike that of Oolong tea. The taste is similar to that of inferior black tea, quite bitter, but with little flavour. Besides the different varieties of " tea " described above, there are several plants the leaves of which are used by people in various parts of the world for the preparation of a refreshing drink. Thus, in the Australian colonies the leaves of species of Leptospermum and Melaleuca, plants belonging to the Eucalyptus family, have been employed as tea, though the quality is not all that could be desired. The famous " Bushman tea " of South Africa is prepared from Cyclopia genistoides, and the lemon grass yields an infusion which is drunk by natives of some of the inland districts of India. " Bourbon tea," sometimes known as " Faham tea," is especially interesting since it is one of the very few examples of a product of economic value derived from the Orchid family. The orchid in question is Angraecum fragrans, which is found growing as an epiphyte on the trees of the forests of Bourbon, or Reunion, and Mauritius. It is a perennial, producing a few green leaves which have a persistent vanilla-like odour. The beverage is prepared by pouring cold water on to the dried leaves, and boiling the liquor for about ten minutes in a tea kettle or other closed vessel. It is then emptied into the cups or tea-pot, and sweetened according to taste. The tea possesses an aroma of great delicacy, and leaves a lasting fragrance in the mouth. COFFEE The popularity of coffee needs no emphasising, and yet it is only during the last 250 years that this beverage has come to be generally used in the civilised countries of Western Europe. Coffee is now one of the important plants of tropical agriculture, and the annual value of the product is enormous. It has been estimated that there are some 50,000 coffee estates in the world, and that they annually produce coffee to the value of over £50,000,000. To a greater degree than most other agri- cultural i n d u s.t r i e s , coffee cultivation has been subject to strange vicissitudes. Originally all the coffee consumed in Europe came from Arabia, then the West Indies, and, later, Java A COFFEE PLANTATION AT BASOKO 175 176 The World's Commercial Products A LIBERIAN COFFEE PLANT IN FLOWER became pre-eminent, to be in turn abso- lutely beaten by Brazil, which at the present time pro- duces some three- quarters of the world's total supply, and controls the market. The history of coffee cultivation in Ceylon, to which we shall refer again later, affords a good illustration of these variations in fortune. In 1880 coffee was the principal crop of the colony, and worth some £3,000,000 annually. The at- tacks of a micro- scopic fungus ruined the plants, and the industry within a comparatively few years became of quite minor import- ance, and the annual crop is now worth only about £25,000 — a drop in value of £2,975,000 in less than thirty years. THE COFFEE PLANT The coffee plant belongs to the genus Coffea of the natural order Rubiaceae, an assemblage of plants including also the cinchonas, which yield quinine ; gambier, furnishing the tanning material and dye of the same name ; madder, and other useful plants. The order is most abundantly represented in the tropics, and our British representatives — the bed-straws, goose-grass, and madder — do not possess the characteristic features of their relatives of the warmer regions of the world. Altogether there are about eighty recognised species of Coffea, of which only two are cultivated to any great extent, namely Arabian Coffee {Coffea arabica) and Liberian Coffee (C. liberica). Arabian and Liberian Coffee The beautiful Arabian coffee plant is a shrub attaining a height of fifteen or eighteen feet. Its leaves are of a fresh green colour, three to four inches in length, pointed and borne in pairs 177 n— c.p 178 The World's Commercial Products LIBERIAN COFFEE. FLOWERS AND RIPE FRUITS OR " CHERRIES " on the slender branches. The flowers occur clustered in groups of from four to sixteen in the axils of the leaves. They are white in colour and of fragrant odour. The fruits, or so-called " cherries," are at first a dark green, but as they ripen the colour gradually changes to yellow and then to red, and at last, when thoroughly ripe, to dark crimson. The outer portion of the fruit is fleshy like a cherry (whence the common name). Each fruit contains two seeds, covered in turn by a dry, smooth, straw-coloured husk, known as the " parchment." The seed itself is of a horny consistency, and will be perfectly familiar to everyone, as it is the unroasted coffee bean of commerce, of characteristic greenish-grey colour. Between each seed and the parchment is a thin membranous covering known as the " silver skin." The two seeds or " beans " which each fruit contains lie with their flat sides together. It often happens, however, that only one of the beans attains full development, in which case it is no longer flat on one side, but more or less circular in section. Such beans form the so-called " pea-berry " coffee. They are carefully separated when the crop is gathered, because they fetch a higher price. In Brazil there is a very rare variety known as the Hybrico-coffee, the fruit of which contains four or six seeds. The native country of Liberian coffee is not only the negro-republic of that name, but also the other parts of the West Coast of Africa, from Sierra Leone to Angola. Its cultivation is of much more recent date than Arabian coffee, because the product is less valuable ; and its first appearance on the European market met with only very moderate success. The first Liberian plants were introduced into Ceylon and into Java after the fearful coffee-leaf disease broke out, in the years 1873 and 1878 respectively. At first it was thought that the Liberian 179 180 The World's Commercial Products coffee-plant was not susceptible to the malady ; this opinion was, however, cruelly belied, although it was indeed less susceptible, and offered greater resistance than its Arabian cousin. Hence people have gradually learned to appreciate the Liberian plant, if not on account of any superior quality of its fruits, at any rate on account of its power of resistance and its vigorous growth — for which reason it has gradually gained a place for itself in Eastern countries by the side of the Arabian coffee. In America, however, the Arabian variety still holds its own. The Liberian plant is distinguished from the Arabian by its greater height, which varies between eighteen and thirty-six feet, and also by the dimensions of its leaves, which sometimes attain the length of one foot. The flowers grow in clusters of six or eight together in the axils of the leaves, and exceed those of the Arabian plant in size, while the fruits are also much bigger, having a diameter of about an inch, and do not drop so readily when they are ripe 1 .. mfm'L WL ^ \ 9 l^^lfl W- wk tpSw* I M Ikt I ^St!^ L a A FSfigE j^jfc... FRUITING BRANXH OF ARABIAN COFFEE {The background is formed by banana leaves) as do those of the Arabian plant. The pulp is less rich in sugar and tougher than that of Arabian coffee, which makes the use of special machines necessary in its preparation. The aroma of Liberian coffee is not very highly appreciated, which, considering its many other good qualities, especially its great fertility, is much to be regretted ; for this reason people in Java have endeavoured to improve the species. Attempts have been made to attain this end by artificial hybridisation, and for a long time, in Java as well as in British India, the hope was cherished of obtaining a race which would unite the merits of Arabian and Liberian coffee. These efforts, however, have not proved very successful, although in a book published in 1899 M. A. J. Thierry records that in Java, owing to the labour of van Riemsdyck, a hybrid has been produced which, when grafted on to Liberian roots, is said to be resistant to coffee-leaf disease. The grafting of Liberian on to Arabian coffee has not been successful; although the results of experiments in the opposite direction were quite satisfactory. Among other things, it was Coffee 181 observed that such plants suffered less from the attacks of parasites, than those which had not been grafted, especially from those parasites — such as nematode worms — which frequently attack the roots of the Arabian coffee plant but do not usually attack Liberian coffee. By grafting we thus obtain the advantage of the hardy root system of Liberian whilst the produce from the grafted stems is the more highly esteemed Arabian coffee. The famous Buitenzorg Botanic Gardens, near Batavia, where experiments are made with all kinds of tropical plants, furnished the first seeds of Liberian coffee to the planters of Java in 1878. Since that time the cultivation of this kind of coffee has so rapidly progressed, that at present one-tenth of the State plantations are planted with- shrubs of this sort, and one-fourth of the private plantations also. NURSERY OF COFFEE SEEDLINGS UNDER THE SHADE OF TREES Other Varieties of Coffee Over and above the two chief kinds of coffee — -Arabian and Liberian — which are described above, the following varieties deserve mention, on account of some peculiar characteristics. The Hybrico-coffee of Brazil already mentioned, with its fruits containing four or six instead of two seeds. The Maragogipe, found in 1870 near the town of the same name of the Brazilian province of Bahia. The leaves of this kind are as large as those of the Liberian coffee, and the seeds are so much in request that people have tried to grow it elsewhere, but accounts vary very much as to its yield. The Botucatu (var. amarilla), discovered in the year 1871 in the district of the same name in the province of San Paolo, which the English have introduced into India under the name of " golden drop coffee," but of which the cultivation is not very important. Experiments have been, and are still continually being made, with numerous varieties in the hope of finding a sort fit for cultivation. These experiments are conducted in various parts of the world with the wild Congo coffee (Coffea robusta), and in the Botanic Gardens of Ceylon, Trinidad, and elsewhere, with the Sierra Leone coffee (Coffea stenophylla), the beans of which are said to be superior in flavour to those of all other coffees. Another species of coffee {Coffea 182 The World's Commercial Products excelsa) has recently been introduced into the Trinidad Botanic Gardens, and is reported to be of considerable value. Cultivation As the methods of the cultivation of coffee and itsjpreparation for market differ to some extent in various parts of the world, it will be best to give first a general account of the processes adopted, and to supplement this afterwards with notes on the industry in the different producing countries. Coffee thrives to the best ad- vantage in a hot, moist climate, and on rich, well-drained soil. A high rainfall is usually essential, and anything between 75 and 120 inches per annum is desirable, well distributed. It is true that coffee can be grown in dry regions and yield produce of excellent quality, but then the crop is usually very small. In the tropics coffee is pre-eminently a crop for fairly high elevations, and the best results are attained on estates situated above 2,000 feet, although it will grow almost down to sea level. Liberian coffee gives good results at lower elevations than Arabian. In South America the coffee grown in very dry regions, situated rather high above the level of the sea, is considered the most fragrant ; the fruits are much smaller, how- ever, and the crop less plentiful. In damp regions, above a certain degree of latitude, the plant bears a very rich foliage, at the expense of the fruit. The two things most injurious to its growth are cold, and very hot, dry winds. If the plant is not protected it loses a large part of its foliage on the windy side ; sometimes it is even entirely despoiled of its leaves. To prevent this, trees are planted round the coffee plantations to shelter them from the wind. Propagation. Coffee plants are propagated from seeds, for which the largest and finest fruits from selected trees should be chosen. The seeds may be planted directly in the fields in the positions the future trees are to occupy. The method is commonly known as " planting at stake," because a stake is driven in to mark the position of the seeds, three or more being planted together so as to allow of the weaker plants being pulled up later. This method has several advantages as it does away with the expense and risk of transplanting. On the other hand, if the climate is not sufficiently moist, there is always the possibility of drought injuring, or even killing, the young seedlings. If there is any likelihood of this happening the young plants must be raised in nurseries. When this course is advisable the seeds JAVA. GRAFTED COFFEE PLANTS 183 184 The World's Commercial Products are sown in carefully prepared and thoroughly well-tilled nursery beds, situated so that the plants can readily be watered. It is necessary to afford shade to the young plants, and this can be done by arranging coarse matting, palm leaves, etc., on a framework three or four feet above the ground. When the plants are about one to two feet high they are transplanted to their permanent situations, this being done at a season when showers are frequent. Before transplanting the shade is gradually removed and the plants hardened off exactly as in this country one would prepare seedlings for the difference in climate between a frame, or green- house, and a situation in the open.. After being transplanted temporary shading is afforded by palm leaves, leafy branches, or in other ways, each country and sometimes each estate QUEENSLAND. COFFEE EIGHTEEN MONTHS AFTER BEING PLANTED OUT having its own method in these matters of detail. The distance between the plants varies, but from ten to fifteen feet apart may be taken as about the average planting distance. Catch crops can be cultivated between the rows whilst the coffee plants are young and small. In Brazil, for instance, maize and beans are planted between the young shrubs. These give a useful crop and at the same time serve to shelter the coffee from the sun. Bananas and plan- tains are commonly employed in a similar way. As soon as the coffee plants become well developed and begin to bear fruit, the other plants should be removed unless there are special considerations which render their retention advisable for a longer period. Weeding is of great importance in the coffee plantations and requires great care, for in regions of such luxurious growth grasses and weeds display an extraordinary vitality and vigour. In Brazil, with its dry climate, where the coffee-shrubs are planted at sufficient distances from one another, mechanical weeding-knives drawn by negroes are used to clear the plantations, a method which is very little known in other countries. Coffee 185 Shade Trees. So far we have only spoken of the temporary shade provided for the coffee whilst it is young. Permanent shade trees are also often planted, amongst the favourites being species of Erythrina and other leguminous trees. The necessity for these is a disputed question. Certainly, excellent coffee can be grown without shade, for instance, the Blue Mountain coffee of Jamaica, and in Brazil also shade is not usually employed. The planters of other countries, such as Porto Rico, say that the plants absolutely require shade. Local •conditions probably have much to do with this difference of opinion, and it is one of those problems which, as in the case of cacao, each planter must solve for himself as the result of JAVA. LIBERIAN COFFEE PLANTS THREE TO FOUR YEARS OLD his own observations. The whole question is fully discussed by Mr. O. F. Cook in an interesting Bulletin of the United States Department of Agriculture, entitled " Shade in Coffee Culture," in which the complex nature of the problem is well brought out. In all probability where shade- trees are found to be advantageous their beneficial action is often only indirect, in affording protection from winds, drought, soil erosion, and in that increase of soil fertility which leguminous plants, as a group, bring about. Fruiting. As a rule the coffee shrub first flowers in its third year, and then only bears a small crop of fruit. The fifth year is usually the time of the first considerable yield. Climate and soil have great influence on the blossoming. Where there are no great differences in the temperature in the different seasons the coffee plant bears flowers all the year through, so that at any time of the year an individual plant will bear flowers and fruit in various 186 The World's Commercial Products LIBERIAN COFFEE CULTIVATION IN SURINAM stages of development. The gathering of the crop and the treatment of the beans are in such places not restricted to definite seasons — a circumstance which is of no advantage, as the quantity gathered at one time is usually small, and the handling and preparation of the crop is more profitable when large crops are dealt with. It is thus preferable to form plantations in regions where the seasons are sharply distinguished from each other. In Java three gatherings are made annually, called the " early," the " chief," and the " after crop," but only the second, which begins at the commencement of the rainy season, is of great importance. * In the coffee-growing districts of Brazil differences in climate have great influence on the time of flowering, the time of harvest, and the quality of the product. Thus, ripening is hastened in the State of Rio de Janeiro, where it is much warmer than in San Paolo, the con- sequence of which is that the crop gathered in Rio is ready for sale at least a month earlier than Santos coffee from San Paolo (April and May), whilst in other districts, such as Braganza and Atibaia, the crop is not ready until October. The flower enjoys only a very ephemeral existence as the setting of the fruit generally takes place within twenty-four hours, and the petals wither and fall off almost inmediately. A coffee estate in full flower is a very beautiful sight, but its glory is very soon past and an estate which was a mass of fragrant white blossom one day becomes green again within a compara- tively short time. From the time of blossoming to the ripening of the fruits there is a period of some seven or more months. ' Picking. It is easy to recognise when coffee fruits are ripe as they are then dark . red, and bear a strong resemblance to ripe cherries. The cherries are readily stripped from the branches by hand, and are collected in bags, baskets, or other convenient receptacles. To obtain the best quality product only the ripe " cherries " are gathered, those which are green and unripe being left on for a later picking. Dry and shrivelled up berries must also be il* H ^ at- •z r~~K H w C/> 9* 'J. £L > <*> ti H •< 0) H o> a s $ w c* (A c\> > a* V 3 tv> «!

The picking requires to be done carefully so as to prevent the plant as well as the fruit from being damaged. The Arabs allow the fruits to mature fully until they fall off of their own accord, or are made to fall by slightly shaking the plants, a cloth often being spread beneath. This ensures only quite ripe fruit" being collected, and is no doubt one reason of the excellent qualities of Mocha coffee. This method, however, is not generally adopted in countries where there is a high rainfall. In Brazil the crop is gathered " da terra " or " do lencal." If the first method is adopted the fruits are made to fall on the ground, which is first carefully cleared of weeds, and the cherries are afterwards gathered up and freed from sand, earth, etc., by sifting. In the alter- native method the tree is shaken and the fruits collected on a cloth (lencal). Formerly. this method was also practised at Santos, but since slavery was abolished in 1888 the gathering <( da terra " (which is not so good, but requires fewer labourers) has gradually taken its place. The fruits are usually carried in carts to the places where further treatment takes place, but on many large, up-to-date, plantations they are transported along galvanised iron spouting by "the agency of running water. Preparation for Market The cherries as gathered each contain normally two seeds or coffee beans. Each bean is enveloped by the thin delicate silver skin, and outside this by the parchment, and both are enclosed in the fleshy pulp of the outer portion of the fruit. All these coverings have to be removed to prepare the beans for consumption. This may be done in one of two ways, JAVA. COFFEE IN FULL FLOWER Coffee 189 NICARAGUA. DRYING COFFEE ON WOODEN TRAYS ( 1 ) the older or dry method, still practised in Arabia and some other countries, and (2) the modern or wet method, often spoken of as the West Indian process. The Dry Method of Preparation The beans are spread out on stone drying grounds, Commonly known as barbecues, in a layer a few inches deep. During the first day or two they are frequently stirred so that all are exposed to the sun, and afterwards means are usually adopted so that they can easily be removed under cover at night or at any other time when there is any chance of their being" made damp again. The pulpy covering ferments and gradually dries, the whole processes taking two or three weeks. When thoroughly dry the beans can be stored any length of time until wanted, when all that has to be done is to remove the dried pulp in a primitive manner by pounding in a mortar similar to those used for husking rice (see illustration on p. 193), or, as is now more usual, in a hulling machine. In either case the dried covering is broken up and the beans set free. The dry method, although it is simpler and requires less expensive machinery, is gradually falling into disuse, and even in Brazil, where it is still prevalent, it is losing ground, because the modern wet method is quicker and is independent of the continuance of settled fine weather over a considerable period. The Wet Method of Preparation In the " wet " method of preparation the cherries as brought in from the field are placed in a large tank full of water. The well-developed cherries are heavy and sink to the bottom, whence they are drawn off through pipes, whilst the immature and bad fruits (which are light) float on the surface, and are treated separately. The ripe cherries are carried directly to machines called pulpers. Pulping. Pulpers are of various types, but one of the oldest, and yet most effective, con- sists essentially of a rough cylinder — more or less like a very large cylindrical nutmeg grater 190 The World's Commercial Products OPEN-AIR DRYING OF COFFEE IN NICARAGUA — which is made to revolve facing a curved metal plate. Between the two there is not room enough to allow the cherries to pass. The cherries are reduced to a pulp by the rasping action of the revolving cylinder. The mixture of seeds and pulp is carried away into a vat full of water, where it is mechanically stirred to cause the seeds to separate from the pulp. The heavy seeds settle to the bottom whilst the lighter pulp is carried away by an overflow of water. The seeds or beans are drawn off and carried in a stream of water to a kind of sieve, and the water is drained away. Fermentation. The beans are not yet clean, but the " parchment " which is still uninjured is covered with a slimy layer which cannot be got rid of in the pulping machine. To remove it the beans are placed in a cistern or vat. Fermentation is set up and allowed to continue from twelve to forty-eight hours or more. When the fermentation has proceeded for a sufficient length of time the beans are removed to another vat and washed. Washing. This is sometimes effected by running in enough water to cover the beans and trampling on them with bare feet when the adherent tissue becomes loosened. Successive rinsings with water, stirring with rakes or by special machinery result finally in leaving the parchment coverings quite clean. During the washing process those beans which are not developed sufficiently and are light float on the surface and are collected separately to be sold as " tailings " of inferior quality. When the washing is completed the beans are strained again and removed to the drying place. Drying. This operation is carried out in much the same manner as the drying of cacao, the actual method adopted depending largely on climatic considerations. With an assurance of continuous sunshine and a dry atmosphere, it is sufficient to spread the beans out on a barbecue or drying floor usually made of stone, with a raised edge. By having sliding roofs to the barbecues, or by the provision of portable drying floors on rails, protection against rain Coffee 191 and dew is easily secured. Other planters use trays, which can be placed on supports above the level of the ground and readily carried under cover when necessary. Drying coffee in such trays is illustrated in the pictures on p. 189 and p. 190. When the sun's heat cannot be relied upon, artificial heat has to be resorted to. One method is to have special drying tables, fitted with steam pipes. The beans are spread on these tables or trays, constantly stirred, and rapidly dried by the application of heat which can be regulated as desirable. The colour of coffee, which has such great influence on the market price, chiefly depends on the quantity of water which the beans contain. Blue beans contain more moisture than the green, and these again more than yellow ones, while slow drying in a damp atmosphere gives the beans the colour of lead. The dried beans are now in the state known as "parchment coffee." Each bean is still covered by the delicate silver skin and that again by the parchment which is harder and stronger in Liberian than in Arabian coffee. The produce is frequently exported in this state, and, for some time at any rate, its quality appears to improve whilst it is kept in this condition. Before, however, the beans can be used the parchment and silver skin must be removed, and this may be done on the estate, at the port of shipment, or at the receiving port or elsewhere, according to weather conditions, supply of labour, and other considerations. Peeling. The removal of the final coverings is known as peeling. Machines of various types are employed, but in all the essential is to crack the parchment without injuring the bean. The coffee must be thoroughly dry before this is done, as then the parchment is brittle and more easily broken up, for example, by rollers. Winnowing removes the light pieces of parch- ment and leaves the heavy beans behind. A further simple rubbing and winnowing gets rid of the silver skin, leaving the beans clean and in the condition of ordinary unroasted coffee. JAVA. STONE COFFEE DRYING FLOORS WITH MOVEABLE ROOFS 192 The World's Commercial Products Sizing. To secure uniformity in size, which is desirable when roasting, the beans are sorted into large, medium and small by passing them through sieves with meshes of certain sizes. The last stage is to pick them over carefully by hand to remove all foreign bodies, broken or discoloured beans, and anything in fact which would lower the value of the product. After the beans come on the market they only require roasting and grinding to be ready for use. THE PRINCIPAL COFFEE-PRODUCING COUNTRIES Brazil The principal coffee-growing districts in Brazil are all included in the four states of Sao Paulo, Rio de Janeiro, Minas Geraes, and Espiritu Santo, lying just within the tropics, as shown in the map on page 177. It is recorded that in 1905 there were in the state of Sao Paulo no- less than 16,015 coffee estates. The coffee-producing region is but a very small portion of SURINAM. DRYING COFFEE ON PLATFORMS WHICH CAN BE RUN UNDER SHELTER Brazil, which is nearly as large as all Europe, and much more coffee could be grown in the country if required. The consumption of the world, however, remains fairly stationary at about 16,000,000 bags (of 120 lb. each) per annum. All the other coffee countries put together produce about 4,000,000 bags, whilst for Brazil alone the crop for 1906 is expected to reach the enormous total of 16,000,000 bags, and some estimates put it as high as 18,000,000. The aim in Brazil now is rather to reduce the crop in order to maintain prices, and a tax has been imposed on new coffee estates. The present great production is largely due to the high prices which ruled from 1887 to about 1895, and encouraged planting enterprise. In 1901-2 the coffee crop of the world reached its maximum, and the lowest prices for the product were experienced in 1903-04. Other South American Countries In Venezuela and Columbia, situated in the northern and hottest portion of South America, coffee is extensively grown, chiefly in the mountain districts. From Venezuela the annual COFFEE Coffee 193 export is worth about £1,500,000, and mostly goes to France, the United States, and Germany. The exports from Columbia are of much the same value, and the greater portion is taken by the United States. Bolivia is sometimes allowed the honour of producing the best coffee in the world, that from the Yungas district being considered superior even to Mocha. Bolivian coffee is not important commercially, as the supply is not equal to the home demand. Ecuador and Peru both export coffee, and steps have recently been taken to develop an industry in Paraguay. hulling coffee in java Central America Guatemala is the most important coffee-growing country in this region, exporting coffee to the value of from £1,000,000 to £1,500,000 per annum. About one-half the crop goes to Germany. Coffee is the principal industry, and is estimated to afford emplovment to about half the population at crop time. West Indies The production in Jamaica is described on p. 195. Haiti is the principal coffee island of this group, producing coffee to the value of about £500,000 annually. In many of the islands coffee can be easily cultivated and is grown to some extent, if only for home con- sumption. Porto Rico formerly had a nourishing coffee industry, but its value has considerably 14--C.P. 194 The World's Commercial Products SORTING COFFEE IN MEXICO diminished. Under the Government of the United States, experiments are being made to cultivate coffees of the type most in favour in the United States market, and to improve cultural methods. First-class Java coffees are being taken as the standard, and every effort is being made to obtain a product which can hold its own in competition with them. Arabia The name Mocha coffee is applied generally to the coffee produced in Arabia. The best portion of the crop goes to Turkey and Egypt, being purchased on the trees by traders who themselves look after the picking and preparation. The coffee which reaches Mocha for sale is that which is not considered worthy of purchase by those traders. Dutch East Indies The produce from Java, Sumatra, Celebes, and Borneo is known generally as "Java coffee," and the greater part comes from Java. The plantations are largely owned by the Government, and great care is taken in the cultivation and preparation. The best Java coffees are of very high quality. COFFEE PRODUCTION IN THE BRITISH EMPIRE The chief coffee-producing countries in the Empire are India, Jamaica, British Central Africa, Trinidad, and Ceylon. Small quantities of the product are grown also in Queens- land, British Honduras, and Natal, whilst in almost every part of the tropical regions of the Empire one or other species of coffee is cultivated for local use. India As might be anticipated from the fact that this country is the chief source of " British- grown " coffee consumed in the United Kingdom, and of some twenty per cent, of our total supply, India is the principal seat of coffee production in the British Empire. The most recent returns estimate the area under coffee cultivation in India as close upon 213,000 acres, Coffee 1 95 almost all in Southern India, and about one-half in Mysore. The general tendency appears to be to decrease the area under coffee in the country. The United Kingdom and France take by far the greater part of the coffee exported. Jamaica The " Blue Mountain " coffee of Jamaica is famous and commands higher prices than any other kind of coffee. It is grown at elevations between 3,000 and 4,500 feet on estates situated in the beautiful mountain range whence it derives 'its name — in a region where the climate is cool, and rain, alternating with -brrglrfsunshine, is obtainable all the year round. The output of the better grades is limited to rather less than. 8,000 cwt. per annum. The total export of coffee varies, however, between 50,000 cwt. and 100,000 cwt., and it usually stands about third or fourth in order of value amongst the products of the colony. British Central Africa Coffee is the principal export of British Central Africa, and the Protectorate stands alone in the British Empire in this respect. The introduction of coffee. into the country is quite a recent event, comparatively speaking, having taken place in 1878. By 1896 coffee was by far the most important item in the list of exports. During the last ten years the value of coffee exported has been altogether about £242,000, whilst during the same period the total value of all exports — cotton, rubber, tobacco, and ivory, in addition to coffee — -has been about £350,000. The area under coffee reached its maximum in 1901, when it was 16,917 acres ; it decreased more or less steadily, until in 1904 it was 8,867 acres. Last year there was a sudden drop to 4,880 acres. The diminution in coffee cultivation has been due to the general depression in the coffee market and locally to droughts to a considerable extent. .The great fall between 1904 and 1905 appears to be due to the increased attention given to cotton. The coffee estates are chiefly situated in the healthy Shire Highlands, and Arabian coffee is almost entirely grown. MEXICO. THE LAST EXAMINATION BEFORE SHIPMENT 196 The World's Commercial Products ROASTING COFFEE Ceylon "A quarter of a century ago coffee was the principal product of the colony, and the value of the annual crop exported exceeded £3,000,000. Now it is only about £25,000, whilst the tea occupies the premier position. Coffee Leaf Disease. KThe Ceylon coffee industry was ruined owing to the attacks of a minute fungus, known as Hemileia vastatrix, very similar to the rust of wheat. The disease was .'first noticed in 1869, when it was already fairly well distributed throughout the island and had probably been in existence for some time. The characteristic outward sign of the disease is the formation of a number of yellow spots on the surface of the leaves. Owing, to the fungus using up the plant's food, the coffee plant is weakened, its leaves fall long before they would if not attacked, only a small proportion of the flowers develop sound fruits, and accordingly a very poor, crop is the result, whilst the whole plant is weakened and may finally be killed.* The disease was very carefully investigated by the late Professor H. Marshall Ward in 1880-81, but no curative measures could be discovered. Coffee estates had to be abandoned, and many planters were ruined. Some tided over the crisis by cultivating cinchona (see Drugs), and, later, tea was actively taken up. The greatest assistance was rendered by the Botanic Garden, and the Ceylon planters displayed wonderful energy in meeting the disaster. Within a year or so after the disease was noticed in Ceylon it appeared in Southern India,, and rapidly spread to other countries also, the spores probably having been introduced in various ways ; practically all the coffee-growing regions of the Old World were, affected. The disease is so dreaded that other countries took, and still take, every possible precaution to guard against its introduction. THE PRINCIPAL COFFEE-CONSUMING COUNTRIES First in importance are the United States of America, which import for home consump- tion about one-half of the world's commercial coffee crop. The average consumption per Coffee 197 head in the United States is very high, about 11 to 121b. per annum, which, is equalled or exceeded only in Norway, Sweden, and Holland. ' We "take the lowest position, the average consumption per head in the United Kingdom being less than. 1 lb. ^per annum. Similarly in Canada, each individual uses on the average less than 1 lb. of coffee yearly, solhatthe relatively enormous consumption in the United States is rendered the more striking. Germany follows the United States, using considerably less than one-half the total of the latter country, but then the individual consumption in Germany is only between 6 and 71b. per annum. France, Austria-Hungary, and Holland are next in order of consumption. Sweden, Belgium, and the United Kingdom form another little group, each taking about half the amount used in Holland or Austria-Hungary. In Sweden and Belgium there is' a high individual consumption, whereas in the United Kingdom, as already noted, it is very low. THE ACTIVE PRINCIPLE OF COFFEE The stimulating and refreshing action of coffee is mainly due to the presence of caffeine and a volatile oil. Caffeine belongs to the group Of substances known as alkaloids, which as a class have usually a bitter taste and are only slightly soluble in water. Amongst other well-known alkaloids are cocaine, the active principle obtained from coca leaves ; morphine, codeine, and narcotine, the essential constituents of opium; quinine and cinclionine, to which the bark of cinchona owes its properties ; theobro- mine contained in cacao. Theine, the alkaloid of tea, is practically identi- cal with caffeine, and both are very similar to theobromine. Paraguay tea or Mate and kola nuts contain caffeine. The quantity of caf- feine present varies greatly in different species of coffee. It is never very large in amount, slightly under 2*0 per cent, of the dry seeds being the highest recorded. Analyses of Arabian coffee show a range of between 0*7 and 1*6 per cent., whilst Liberian coffee varies from about l'O to 15 per cent. The wild Sierra Leone coffee (C 'off 'easteno- phylla) contains about 1*5 per cent. Four spe- cies of coffee, natives of Madagascar or of the neighbouring islands, do From p koto by pennon 0/ not contain any caffeine. Jamaica coffee tree '"Son Kingston, Jamaica 198 The World's Commercial Products COFFEE SUBSTITUTES AND ADULTERANTS Various substances have been used as adulterants of, or substitutes for, coffee. In most instances the object is to increase the profits by selling at the price of coffee a much cheaper article. r Chicory It is difficult to know whether chicory should be described as a coffee adulterant in all cases, because there are many people who prefer the addition of chicory. , Ghicory is prepared from the fleshy roots of Cichorium Intybus, a plant closely related to the lettuce, and found wild throughout a great portion. of Europe, North Africa, Siberia, and Northern India. In parts of the United Kingdom it is a conspicuous wayside plant with cornflower blue flowers. Chicory was formerly the basis of an industry of some importance in England, and at one time about half the chicory used in this country was produced at home. About 1860 over 1,500 acres were devoted to this crop in Yorkshire alone. Various circum- stances, however, have effected a great reduction in the crop. The removal of protective duties in 1854, coupled with the imposition of excise duties from 1860 onwards, had much to do in bringing about this result. The total area under chicory in the United Kingdom is now only some forty acres, and the preparation of the roots is only practised at York and St. Ives. At the present time the home-grown article contributes merely about two per cent, to the annual consumption, the great bulk of the imports coming from Belgium. In addition to its legitimate use, chicory is often employed to adulterate coffee, and some- times as much as ninety per cent: of chicory has been detected in ground " coffee." It must be remembered that whereas coffee is worth, say, about Is. 6d. per lb., chicory costs only 4d. per lb. A simple test whereby to detect the presence of chicory is to put a little cf the ground material in a glass of water. Coffee remains hard and floats on the surface for a long time ; chicory soon softens, and sinks, colouring the water more or less brown. Other Substitutes and Adulterants The substances which have been found as adulterants in ground " coffee " are very varied, including cereals, sawdust, bark, cacao husks, acorns, figs, lupine, peas, beans and other pulses, and even baked liver. Colouring materials are also used to improve the appearance of poor and damaged beans. Artificial beans composed of such ingredients as flour, chicory and coffee, or bran and molasses have been manufactured, the mixture being ground up, made into a paste, and moulded into the form of the genuine article. A few seeds make a palatable infusion with water and are used to some extent as substi- tutes for coffee, although they lack its stimulating properties. One of the best known is Negro Coffee, or Mogdad Coffee, the seeds of Cassia occidentalis. The seeds of a species of Ipomea, the ochro (Hibiscus esculentus), and the soja bean are also employed for the same purpose. TOBACCO Tobacco is prepared from the leaves of several species of Nicotiana, a genus of plants belonging to the natural order Solanaceae, a family which includes the tomato, potato, egg-plant, deadly night- shade, and many other well-known plants. The species of Nicotiana are nume- rous, but those of which the leaves are used as tobacco are very few. The great bulk of the world's supply of tobacco is derived from N. Tabacum, PACKING CIGARETTES IN HOLLAND Tobacco 199 CLEARING THE FOREST FOR TOBACCO IN SUMATRA which is very largely cultivated in the United States, Cuba, the Philippines, and also in Holland, Germany, France, and some other countries. It is a handsome plant, the upright unbranched stem reaching a height of from three to six feet or more, and bearing large, pointed, oval leaves, which at the base of the stem are slightly stalked while those towards the upper part are without stalks and clasp the stem. The pink or rose-coloured flowers are funnel-shaped, and borne in a branched inflorescence at the top of the stem. The whole plant, with the exception of .the flowers, is viscid to the touch, due to the occurrence of soft hairs which secrete a resinous juice from the cells at their apex. East Indian, or Green Tobacco, is obtained from another species of Nicotiana, viz., N. rustica, originally a native of Mexico, but now extensively cultivated in Southern Germany, Hungary, and the East Indies. The plant is smaller than the preceding, with a much- branched stem, but grows more quickly, and not only ripens earlier, but is more hardy. The flowers are greenish or pale yellow, and the leaves are shorter and broader in proportion than those of the American plant. While N. Tabacum produces the various grades of American and Turkish tobaccos, and also the famous Latakia variety, N. rustica is the source of the Hungarian tobaccos, and also affords much of the East Indian leaf. In the opinion of many connoisseurs, the finest tobacco in the world is the Persian variety, known as Shiraz tobacco, and this again has an origin different from either of the two mentioned above, the plant concerned being N. persica. It must not be supposed that the species of Nicotiana cultivated for tobacco exhibit no variation in botanical characters when grown in different parts of the world, for the first two species mentioned above possess numerous varieties ; but, in the two species N. Tabacum and N. rustica and their many varieties, and perhaps N. persica, (which is regarded by many authorities as a mere variety of AT". Tabacum), we have practically the only members of the large genus Nicotiana, which are the sources of commercial tobacco. N. repanda, however, is said to have formerly furnished some of the best cigar tobaccos of Cuba, and N. latissima is 200 The World's Commercial Products 1 _ "Is i\ BUFFALO PLOUGHS AT WORK ON A SUMATRAN TOBACCO FIELD reported to yield the variety known as Orinoco. The subject of the botanical source of the chief commercial tobaccos will be more fully dealt with later. The question as to the original home of so important a plant as tobacco — using the term to include the three species mentioned — is naturally one of very great interest, and has given rise to a considerable amount of discussion. Briefly stated, the question resolves itself into deciding between the claims of the Old and the New World as the home of the plant which is now equally common in both. For a very long time, indeed up to the middle of last century, it was by no means certain that truly wild plants of at any rate AT". Tabacum had ever been gathered in America by botanists, and Fliickiger and Hanbury in their great work on the History of Drugs stated that " the common tobacco is a native of the New World, though not now known in a wild state." Later, however, evidence was forthcoming for the occurrence of the plant in the wild condition. With regard to N. rustica, many botanists have been inclined to ascribe to this plant an Eastern origin, and the plant most certainly has the appearance of being perfectly wild in many districts of the Old World. But authors of the sixteenth century spoke of this species as a plant introduced from foreign countries, and there can be little doubt that its occurrence under apparently perfectly natural and wild conditions is due to its escape from cultivation. The evidence for a non-American origin of tobacco appears, therefore, to be of a very slight character, and De Candolle sums up the question in characteristic fashion. He finds that of all the numerous species of the genus Nicotiana found in a wild state, only two are foreign to America, and both of these occur in Australasia : N. suaveolens of Australia, and N. fragrans, found in the Isle of Pines, near New Caledonia. Further, in the contention that all Eastern peoples are great lovers of tobacco, and have indulged in the habit of smoking from very early times, he finds no support for the Asiatic origin of the tobacco plant, for the narcotic "smoked " was quite different from tobacco and was derived from a variety of plants, one of, the most commonly used being "bhang," the dried leaves of Indian hemp (Cannabis sativa). Again, the writings of travellers in. the East up to the thirteenth and fourteenth centuries make no mention of ;tobacco and,- in factj we are in possession of no certain evidence concerning the use of tobacco in Asia until the seventeenth century, i.e., until after the introduction of the plant into Europe. Taking, therefore, these facts into account, we are forced to the conclusion that tobacco reached the East via Europe, i.e., ultimately from America.,* -Evidence of a very valuable kind in determining the home of a plant is afforded by a study of the names under which the plant is known in different parts of the world. If a plant has a wide distribution and has been known in different countries from the most remote times, it will almost certainly -receive names which etymologically are distinct. Now in the case of tobacco, the plant is known throughout the New World by names which can be very readily recognised as mere corruptions of " tobacco," a word which, as we shall see later, is of undoubted American Tobacco 201 origin. The evidence afforded by this line of reasoning, therefore, points to the general intro- duction into the New World of a plant which was already recognised under an accepted name, and this name was that under which the plant was .received in Europe from America. The only remaining point for us to consider is the validity of the statement which ascribed two indigenous species of Nicotiana to Asia, viz., N. ftcrsica, to which we have already referred, and N. chinensis, which was stated by the Russian botanist Fischer to be of, Chinese origin. The former is in all probability a variety of a Brazilian plant, which must have been introduced into Persia by seed, and the latter has proved to be merely N. Tabacum. Summing up, then, we find that, in all probability, there are no truly Asiatic species of Nicotiana, which is a typically American genus, and the only two species occurring outside the Western hemisphere are N. suaveolens and N. fragrans, both of which are found in Australasia. The origin of the word "" tobacco " has given rise to a certain amount of discussion. One view inclines to the belief that the word is derived from the island of Tobago, in the West Indies, the chief evidence in support of this opinion being that, when in 1520 Ferdinand Cortez gained a great victory in this island he found extensive plantations of tobacco in several districts. The plantations, however, were no larger than others which had been previously noted in other parts of America, and there seems no reason to regard Tobago as the home of tobacco, from which the herb received its name. Benzoni, an early American explorer, states in his :' Travels in America " (1542-1556) that the native name of the plant in Mexico was " tabacco." There seems to be little doubt, however, that the true origin of the word as it was received in Europe was derived from the name of a peculiar piece of apparatus used by the natives of San Domingo in smoking the herb. When the Spaniards visited this island in the early years of the sixteenth century, they found the people inhaling the fumes of burning tobacco through a double pipe which was inserted in the nostrils. The " pipe " was of narrow diameter and Y-shaped, the arms of the Y being sufficiently close together to be held in the nostrils with comfort, while the leg of the instrument was held in the fumes of tobacco which were thus drawn up into the nose and inhaled. This " pipe " was called by the natives " tabaco," and there is little doubt that in it we have the origin of our " tobacco." It should be noted that the smoking pipe of the Indians of the American mainland was quite different from the tabaco, and corresponded, roughly speaking, to the modern type. PLANTING UP NEW LAND IN TOBACCO 202 The World's Commercial Products The Discovery of Tobacco by Europeans Having thus briefly dealt with the botany and probable origin of the tobacco plant, we will now turn our attention to some of the chief points in connection with the introduction of tobacco itself into the countries now mostly addicted to its use. As has been stated above, the practice of resorting to the inhalation of narcotic fumes in order to allay excitement and to produce a pleasant general sense of comfort has long been known among Eastern peoples. Thus we have mention of the practice in the writings of Herodotus, and the habit was known among the ancient Gauls, who employed hemp for the purpose. BRITISH NORTH BORNEO. YOUNG TOBACCO PLANTS UNDER SHADE The first trustworthy mention of tobacco as the narcotic employed was made by Christopher Columbus. In the latter part of 1492, Columbus despatched a small expedition from among his ships' crews to explore the island of Cuba, and the men, on their return, reported that the inhabitants of the island perfumed themselves with a certain herb from which they drew clouds of smoke. The herb was dried and rolled in a piece of maize-leaf, which was lighted at one end and held in the mouth at the other, a description which would be roughly accurate for a modern cigarette or cigar. During his second voyage to America in 1494-6, Columbus was accompanied by Ramon Pane, a Franciscan monk, who describes the habit of snuff-taking among the Indians, and later the Spaniards observed the practice of tobacco-chewing among the natives of South America. As the Spaniards penetrated into the new countries it became more and more obvious that these practices, especially that of smoking, which up to the present had been probably regarded as mere local customs, were an ancient and universal usage ; and later exploration and study showed that they were intimately bound up with the most solemn rites and ceremonies of the native peoples. Other explorers, following Tobacco 203 in the footsteps of Columbus, realised the importance of the plant and its undoubtedly valuable properties, and in this connection mention must be made of the names of Petrus Martyr and the famous Milanese, Girolamo Benzoni. It fell to the lot of Francisco Fernandez, however, a physician commissioned by Philip II of Spain, to enquire into the economic possibilities of the flora of Mexico, to introduce the plant itself into Europe in 1558. Both plants and seeds were sent to Spain, where it is reported that the plant was much admired on account of its beauty. For some considerable time tobacco was regarded as a medicinal herb only, but its value in this respect was held in the highest esteem, largely owing to the writings of Nicolo Monardes, a famous Spanish physician. The plant was credited with almost miraculous powers, and at this time attained an extraordinary degree of popularity as a medicine ; the most wildly enthusiastic names were ascribed to it, some of the most common being " herba santa," " sana sancta Indorum," " herba panacea," etc. Even in our own country Spenser later describes it as " divine tobacco," and William Lilly as " our "holy herb nicotian." Much of the rapid increase in the popularity of the plant on the Continent was due to the efforts of the French ambassador at the Court of Lisbon, Jean Nicot, and so great were his efforts in this direction that they have been commemorated in the name of the genus Nicotiana. Nicot, on his return to France from Lisbon, took from the Royal Garden at the latter city a plant of tobacco which he presented to Francis II and Catherine de Medicis, recommending it as a drug of great value, and this plant together with others which were forwarded to Nicot from Lisbon soon after his return were the first to be introduced into France. While tobacco thus became introduced into Europe through Spain, and the medicinal properties of the plant was clearly recognised by the physicians of that country, it appears that it fellto Englishmen to introduce the habit of smoking the herb to the inhabitants of the New World. When in 1586, Ralph Lane, the first governor of the new English colony of Virginia, and Francis Drake returned from that colony they brought back with them the cured tobacco leaf for smoking, and, in addition, certain pipes and apparatus used in the process. The tobacco and implements were handed over by them to Sir Walter Raleigh. There seems to be some difference of opinion as to who was the first Englishman to seriously adopt the new habit, but the honour is generally ascribed to Ralph Lane himself, and the stories of the first finding of Sir Walter Raleigh smoking by his servant, and the statement that he " tooke a pipe of tobacco a little before he went to the scaffolde " are too well known to need more than passing mention. No sooner had the custom of smoking become seriously A TOBACCO FIELD IN SUMATRA 204 The World's Commercial Products adopted by a few individuals than it spread with marvellous rapidity among all nations, the most rapid strides in the spread of the habit taking place during the seventeenth century. The rapid increase in the use of tobacco was viewed by the authorities, and especially by the priestly classes, with the greatest concern, who saw in the habit the final_jx)niplete demoralisation of the people. Even in our own country, in- spite of the praises, of the poets, the divines bitterly denounced the new herb which rapidly gained popularity among, all classes of the people, notably among the soldiery. Strong as the opposition to tobacco was in England, the vehemence with which it was opposed was as nothing compared to the drastic measures taken for its suppression on the Continent, and it will be of interest to note the rise of the use of the fragrant weed in the chief countries of Europe. The practice of smoking tobacco did not become general in France until the reign of Louis XIII, when the habit took a great hold upon the people — even women smoking. So great a hold, indeed, that the Government, with possibly more than one object in view, thought fit to levy a tax upon all tobacco im- ported from America. The people, at first, smoked small pipes with a metal bowl fitted with an oaten straw stemr the model being copied from the pipes introduced from Spain ; but very soon it became the fashion to smoke tobacco in pipes of the elabo- rate design used by the Orientals for their bhang and opium. It was not long before a heated controversy arose between the people on the one hand and'* the scholars and physicians on the other as to the morality of tobacco smoking, but the habit grew so rapidly among all classes and the national exchequer was benefited to so great an extent that before long tobacco received royal support, and Louis XIV directed that all his troops, then being despatched on an expedition to Holland, should be provided with tobacco and pipes. Among the upper classes smoking did not become so popular, tobacco being taken more generally in the form of snuff, and, in consequence of this, it was about the end of the seventeenth century that the craze for expensive snuff-boxes set in. The actual date of the introduction of the fragrant weed among that nation of smokers, the Dutch, is somewhat uncertain. In 1590 the physician William Van der Meer wrote that he had seen English and French students smoking the new herb at Leyden, but there is some reason for supposing that the habit had been indulged in by Dutch sailors some years previously. Nevertheless, smoking does not seem to have made any great progress amongst the people at this time, and, indeed, we read that for some years after the preliminary attempts of the students and seamen, tobacco was relegated to the chemist's shop, where, however, it held A CUBAN PLANTATION Tobacco 205 A FIELD OF RIPE TOBACCO a wonderful reputation as a panacea. In the beginning of the seventeenth century the use of tobacco again became general, and soon attained great popularity. The leaf was imported into Holland from the West Indies in relatively large quantities " so that soon over a hundred thousand guilders were paid in Holland for tobacco every year." So great a hold did tobacco obtain over the people, that in 1615 plantations of the plant were actually laid out near Ameersfoort and Zeeland, and soon afterwards the inhabitants of the Gelderland, Utrecht, Noord-Brabant, and Limburg provinces followed suit. Every day new " tobacco houses " or taverns were opened in the towns, where tobacco leaves were retailed by women to the men who sat round the fires and tables of the house cutting up the tobacco and smoking it in their clay, tin or silver pipes ; needless to say, the convivial glass was not without its place at these gatherings, and soon all classes, both rich and poor, spent a considerable part Of their leisure indulging in the new habit. It was at this stage that active opposition to tobacco began to make itself felt in Holland. The General and Provincial Governments attempted to check the habit by the issuing of severely worded proclamations and the imposition of heavy duties ; the municipal authorities imposed fines on persons found " sucking " tobacco ; the governors of orphan asylums and religious institutions forbade tobacco smoking under pain of instant dismissal or even im- prisonment ; and finally, it was made impossible for the country's military and naval defenders to obtain any of the weed at all. Nevertheless, in spite of all efforts by well-intentioned people to the contrary, smoking spread with great rapidity among all classes. The importance of the tobacco trade to Holland grew rapidly, and at the beginning of the 206 The World's Commercial Products eighteenth century had reached considerable dimensions, for not only was the Dutch market itself of great value, but the geographical position of the Dutch ports and the flourishing condition of her mercantile marine rendered Holland a very convenient distributing centre ,for the principal smoking countries of Europe. Large quantities of leaf were imported into Amsterdam from Virginia, and soon supplies came also from the West Indies — Jamaica, St. Vincent, Antigua, Dominica, Cuba, and Brazil. Further, the home cultivation of tobacco rapidly increased and, before long, practically every suitable area in the Utrecht, Gelderland, and Ameersfoort districts was planted up in tobacco. It was not long, however, before the inevitable reaction set in, and in a very few years large numbers of the tobacco merchants and planters were ruined. This debacle was not the result of decreased consumption, but was the natural consequence of over-production, deterioration in the quality of the article supplied, and excessive competition, the latter being especially encountered at the hands of the merchants of Bremen, who were now also endeav- ouring to share in the import trade. Further, the German states at this time levied heavy import duties on Dutch tobacco, and, when similar imposts were made in Belgium, two of the most important of the Dutch markets were closed. By 1760, however, the trade had somewhat revived, and during the American War of Independence the stoppage of supplies from Virginia led to a great impetus being given to the home plantations. It would be difficult to find more confirmed smokers than the Germans, and after its introduction into the coun- try in the sixteenth century, the use of tobacco spread with extraordinary rapidity among the people. Neiner says "from the moment they {i.e., the people) made the acquaintance of tobacco, the habit of smoking spread so rapidly that there was no farmer's cottage where the tobacco pipe was not found ; they sometimes smoke the herb, some- times chew it, and sometimes use it as snuff, and we can only wonder that it has not occurred to anyone to put it into his ears ! " At the magnificent Court of Frederick I tobacco was smoked, and after the Seven Years' War, Frederick II, one of the greatest users of snuff of his time, tried all means in his power to foster the cultivation of tobacco in his dominions ; he consulted the most celebrated botanists and chemists as to the best methods of procedure, and followed the example of France, Holland, Spain, and other countries, in establishing tobacco culture as a prerogative of the Crown. The measures adopted for the suppression of tobacco-smoking were exceedingly drastic in several continental countries. In Russia the herb was solemnly cursed and declared unclean by the ecclesiastical authorities, and in 1630 its use was forbidden by royal proclamation. HARVESTING THE LEAF p J>J I.I so° i it °% i I D 207 208 The World's Commercial Products The people, however, disregarded the patriarchal ban and the orders of the "Little Father," with the result that three years later smoking was forbidden under the penalty of losing one's nose. Even this vigorous measure failed in its object, and, in 1641 the Czar Alexis ordered that, on the third conviction for smoking, the offender should have his nostrils split and be banished to Siberia for life. Many paid the penalty, but smoking became more and more popular — so popular, indeed, that several fires in Moscow were directly traced to the users of the weed. This was the last straw, for, fearing a disastrous conflagration in his capital, the Czar, in 1655, absolutely pro- hibited smoking under penalty of death. In the reign of Peter the Great, however, a great change of opinion took place, and smoking was openly encouraged by the Crown in spite of the prohibitions of the Church. Since that time smoking has steadily increased in the country, and at the present time Russia is one of the chief tobacco-producing countries of the world. The Botany of Tobacco We will now consider, in somewhat greater detail, the species of Nicotiana of value to the tobacco manufacturer, and the classes of tobacco which are prepared from them. Probably the most important is N. Tabacum, variety macrophylla, which produces the Maryland tobaccos. There are two kinds, the Stalkless Maryland, which yields a good smoking tobacco and excellent material for the outer "wrappers" of cigars, and some of its forms, especially those cultivated in Germany and -Holland, are especially adapted for snuff manufacture. The other kind is the Stalked Maryland, which produces a very fine leaf from which probably the finest Turkish tobacco is obtained. Much of the Cuban and Manilla tobacco is regarded as derived from trlis variety. ^Ve then have another variety of N. Tabacum, viz., var. angustifolia, so called on account of its -comparatively narrow leaves. This is the source of much of the Virginian tobacco, but large quantities of snuff are also prepared from this variety which is cultivated to a considerable extent in Germany and also in the East Indies. The world-famous Latakia and Turkish tobaccos are now generally regarded as obtained from a variety- of N. Tabacum, though formerly they were ascribed to N. rustica. The latter species is the source of -Hungarian, Brazilian, and much Asiatic tobacco, and some of its varieties, especially the narrow-leaved Hungarian form distinguished as N. rustica, var. ovata, afford good smoking tobacco, although the yield is comparatively small. N. crispa is the source of the tobacco used in making the famous cigars of the Levant, and is largely grown in many parts of Asia Minor and also in Central Asia.

Tabaciim, and so we must accredit this latter -plant with one more famous tobacco. ■ The Commercial Classification of Tobacco In spite of the interest which attaches to a knowledge of the botanical origin of thejjrincipal types of tobacco, the fact remains that such a knowledge | is of little use to the tobacco manufacturer, for the number of varieties and form, of the chief species is so great that it is a matter of the greatest difficulty to trace any particular grade to its botanical. origin ; and further, the very same variety of tobacco grown on the same plantation for two consecutive seasons may produce a leaf which is adapted for entirely different purposes. In the first'ycar the variety may yield comparatively thin and dry leaves, which are only useful for cigarettes ; while, in the next season, the same variety will produce a heavy leaf suitable for the " wrappers " of plug tobacco. The same plant will also produce several different classes of leaf ;* thus the upper leaves will afford a cheap variety of pipe tobacco, the middle leaves a plug' wrapper, and the lower leaves a good quality of smoking tobacco. For this reason the tobacco dealer disregards all botanical and cultural classifications when dealing with the prepared leaf, and adopts a system of his own. Tobaccos are first of all divided into " classes," a " class " signifying the purpose for which the product is finally intended. Thus, we have the pipe, cigar, chewing, and- cigarette classes, and these are again subdivided into various "types," a classification depending on the combination of certain qualifications of the leaf such as colour, flavour, elasticity, and strength, or on certain charac- teristics produced by the different methods of curing the leaf, e.g., air-cured or sun-cured. We then have a further subdivision into " grades," which are almost endless in variety, depending upon the different degrees of size, aroma, texture, possessed by the leaf. When we are told that it is possible to grade a parcel of Sumatra tobacco from the same field into no fewer than seventy-two grades, it will be realised that such a classification SUMATRA. CHINESE COOLIES BRINGING IN THE LEAF FOR INSPECTION 15— C.P. 210 The World's Commercial Products can only be performed by men who have spent their whole lives in the trade. Mr. G. S. Odium, of the Department of Agriculture for Southern Rhodesia, has summed up the matter in the following words : "To become expert in the classification and grading of tobacco requires life-long experience. All that the farmer can attempt to do is to place all leaves of a certain size, quality, and colour together, and let the buyer classify them as he wishes. This proper assortment of the leaf is one of the most important things .in the whole of the tobacco business. A few leaves placed in the grade above where they belong will largely destroy the selling value of the whole grade, and in case of doubt always place the leaf in the grade below. Many farmers do not receive more than from one-half to three-quarters of the value of their crop, for the reason that they. have neglected to properly classify and grade their tobacco, and hundreds of shrewd -leaf dealers have made their fortunes by buying up this poorly graded tobacco ancl re-grading it." A " Good " Tobacco To attempt to define a "good" tobacco, or even to enumerate its characteristics, would probably be regarded as presumption by the average smoker, for each individual consumer of tobacco is a law unto himself on this important point ! And to a very great extent he is quite right in his contention, for a tobacco re- garded as ideal ,by one man is quite unpalatable to another. Persons leading a sedentary life generally prefer a " mild " tobacco, while those engaged in active out-door employ- ment are generally not content unless provided with a strong tobacco, and it is a =matter •» .. . of common experience with sedentary workers to find that, during a prolonged holiday, in which they enjoy abundance of active physical exercise, a strong tobacco which would have been refused by them under ordinary conditions, is consumed with comfort. In the early days of the tobacco habit there can be little doubt that any tobacco which would burn readily was considered suitable for consumption, and from the quality of the leaf still used by many of the poorer and more primitive peoples of the world it would seem that the idea is by no means extinct. The modern civilised smoker, however, demands a product of good quality, and although the choice of a suitable tobacco is largely a matter of individual taste, there are certain points upon which probably all smokers would agree. One of the most important characteristics of a tobacco is its flavour, a point of the utmost importance when considering the suitability of any variety for cigar manufacture, and by no means to be disregarded in the matter of pipe and cigarette tobaccos. The flavour must be sweet and pleasant, and neither too mild nor too strong. In the manufacture of the best cigars great care is taken to select tobaccos of good flavour for the body or " filler," and at the present day the finest fillers are obtained from the Vuelta Abajo leaf, which is cultivated CUBA. CURING THE LEAF IN- THE OPEN AIR Tobacco 211 with great care in Cuba. The outer wrapper of the cigar is also obviously of great importance, and for this purpose the standard of excellence is the Sumatra leaf, so largely cultivated in the Dutch East Indies, and also in the United States. It is desirable that the wrapper leaf should be as free from flavour as possible, since it comes into actual contact with the lips and tongue of the smoker, but it must possess a light and uniform colour, be thin and elastic in texture, and the veins of the leaf must be small and comparatively inconspicuous. The burning qualities of a tobacco are also of great importance. It must burn readily and yet THE INTERIOR OF A CURING BARN evenly, quietly and completely so that no half-burnt "char" is left, and if the tobacco is intended for cigars the ash must be white and of sufficient tenacity to prevent it breaking readily and spoiling the clothes of the smoker. A chewing tobacco must possess qualities which would render it quite unsuitable for the purposes of pipe or cigarette smoking. It must be very rich in flavour, and, what is of almost equal importance, the leaf must be of a high absorptive capacity, for no small part of the high flavour of such tobaccos is produced by the addition of artificial flavouring matters which are added to the leaf in the form of a liquid or extract known to the trade as a " sauce." Another important point in chewing tobacco is its: degree of toughness, for any leaf which would readily break or powder while being masticated would obviously be of little value ; closely connected with the toughness is the degree of " gumminess " which is so much sought after for this class of tobaccos. It^should be noted that this last-mentioned property is one which must 212 The World's Commercial Products INTERIOR OF A FERMENTATION HOUSE IN SUMATRA be quite absent from leaf intended for pipe or cigarette tobaccos, since the gum would seriously interfere with the cutting of the leaf when placed in the machines. As might be suspected, x it is not often that a single tobacco possesses all the desirable properties demanded by. both the manufacturer and the consumer. In fact, it is very seldom that such an ideal leaf is met with, and it is necessary to blend or mix different grades until a satisfactory article is obtained. Several motives induce the manufacturer to blend his tobaccos extensively. Much of the mixing is, as just stated, carried out with the object of producing as perfect a tobacco as possible, or one to meet the requirements of special tastes. On the other hand, it is a very common practice to add a comparatively small proportion of an expen- sive, first-class, and highly flavoured tobacco, such as Perique, to varieties which are deficient in desirable qualities, with the result that a perfectly satisfactory article of medium quality is obtained. No small part of modern blending, however, is the direct result of the caprice of the taste of the 'consumer. Fashion plays a considerable part in the choice of tobaccos, and constitutes one of the many difficulties which have to be met by the manufacturer. Should the latter place upori the market brands of tobacco which consisted of one variety only, it would be 'highly probable that, should that . particular variety of leaf become scarce at any time, the substitution for it. of a different variety would ruin the reputation of the brand. To avoid tfiis undesirable state of affairs, the manufacturer places upon the market brands which are largely blended from various tobaccos — as many as five different, varieties being sometimes used— in order that, should any particular leaf become scarce, the substitution of another variety will not be markedly noticeable. Tobacco 213 Although individual taste with regard to tobaccos varies considerably with different persons, it is nevertheless a fact that; definite types of tobacco are demanded by different countries and that a variety suitable for one country would be quite rejected by another. • Great Britain demands, on the whole, the best qualities and most highly priced leaf, and is one of the most valuable markets for the products of the United States, the average annual import from America being nearly 93,000,000 lb. of leaf. She is buying more and more, of the better . grades of tobacco, and is rapidly increasing the consumption of the lighter shades of tobacco known in the trade as Bright Leaf. The strongest tobacco imported, is that in- tended for the manufacture of Navy plug, but the most important is a " smoked," some- what olive-coloured- leaf. In former days it was necessary to have a "smoked" tobacco in order to withstand . the long sea transit, and the taste for such tobacco then acquired" has maintained its hold upon the British consumer. The total imports into the United Kingdom now average considerably over 100,000,0001b. per annum, and the amount has more than doubled during the last fifteen years. The-principal sources of our tobacco are the United States (including trans-shipments from Cuba and Porto Rico) with nearly 86 per cent, of the total supply, followed at a very long distance by Holland (chiefly from her colony of Sumatra) with only 5" 1 per cent. Then comes Turkey with 1 per cent., and from British possessions, chiefly North Borneo, we receive 0'8 per cent. All other countries send approximately 3,000,0001b., or roughly 3 per cent. The German demands tobaccos which in many instances closely resemble those imported into England. The leaf must be stout, with plenty of body, and must be rich in oil ; the colour most in favour is a dark red. Large quantities of tobacco are imported into Germany for trans-shipment to many parts of the Continent, notably to Russia, Norway, and Sweden. CARRYING TOBACCO ALONG THE LANGKON ROAD IN BRITISH NORTH BORNEO 214 The World's Commercial Products The supplies chiefly come from the --United States to the extent of some 40,000,000 lb. per annum, and most of the Brazilian crop is also handled by the German dealer. The bulk of the French imports' consist of the poorer qualities of leaf, but thcSwiss, on the other hand, will only take the very best grades, which are mostly used for the wrappers of cigars ; the quantity taken, however, is comparatively small. Italy and Austria import good qualities of tobacco, the latter country requiring a cigar-making material. The tobaccos sent to Spain are, generally speaking, very poor. It will come as a surprise to most people to learn that, with the exception of the Russians, the British consume less tobacco per head than any other of- the principal peoples of the world. The fact, however, remains, for while we use but 2 lb., per head per annum, the Belgian smokes • no less than 6|- lb., and our American cousin requires 5+ lb. a year.

It varies in amount in different tobaccos, the finer qualities containing comparatively little and the coarser sorts up to as much as seven per cent. Nicotine determines to a very large extent the strength of a tobacco, but its aroma and flavour are due to the essential oils of the leaf and also to the aromatic substances produced in the curing and " fermentation," which will be described in detail later. In addition, tobacco contains resins, fats, and certain organic acids to which must be added the ash constituents. Nicotine is extremely poisonous, but in all probability it is in great part destroyed during smoking, the poisonous properties of tobacco smoke being due to the products of destructive distillation of this and other bodies during the combustion, of the tobacco. As regards the physiological effects of tobacco-smoking considerable difference of opinion exists. It is certain that it affects different people in different ways, and for young people there can be no doubt as to its harmful effects. For adults, however, it is hot improbable that the habit has no harmful results if indulged in moderation, but it entirely depends upon the physical constitution and state of health of the individual concerned. 215 <^BRA^ OF THE UNIVERSITY 216 The World's Commercial Products Value.

Although tobacco had long been grown by .the aborigines of the American continent, it was not until. 1610 that the first European plantation was laid out near Jamestown, in Virginia. The cultivation was taken up with energy by the colonists, and before long tobacco was being grown in several states, notably in Maryland and Virginia ; and for more than two centuries the industry was closely bound up with the social and political development of the States concerned: . In Maryland tobacco was actually made legal tender in 1732, at the rate of one penny r)ef pound, for all debts, including the salaries of State officials and clergymen. The industry was very early started in Pennsylvania, but comparatively little THE WORLD'S PRODUCTION OF TOBACCO The five most important tobacco-producing countries, in order of their importance, are the United States, India, Cuba, Russia, and the Dutch colonies in the East, more especially Sumatra. Nearly seven-ninths of the world's total tobacco is raised in these countries. Taking an average of the last few years, the total annual production of nearly £40,000,000 sterling! oducers and the value of the CUTTING TURKISH TOBACCO BY HAND Tobacco 217 attention was given to it until 1828, when tobacco-growing was placed upon a firm footing. The first real extension of the industry, however, was westwards, in the" States of Kentucky and Tennessee. By 1875 it had assumed considerable proportions in the northern parts of the former State, and in 1810 large-areas were under tobacco in all parts of both States, the produce being sent to New Orleans for shipment. In 1838 cigar tobacco was first grown in Ohio from seed obtained from Connecticut, where the industry had already attained considerable proportions. Seven years later theindustry was started in New York State, and in ten years the yield had amounted to more than half-a- tnillion pounds. The history of the tobacco industry in Florida is very interesting, and affords an excellent example of a successful attempt on the part of agriculturists to meet the altered requirements of the market. The cultivation of tobacco was commenced in the earlier years qf the nineteenth century, and the leaf produced, known as " Old Florida," was of such fine quality as to be eagerly sought after as a wrapper for cigars. The industry thrived until the Civil War, when the cultivation had perforce to be abandoned, but when the country had settled down a few farmers continued to grow tobacco in a very small way, so small that' in 1880 the State had but 90 acres under the crop. The industry again revived in 1889, and the planters naturally turned to their famous " Old. Florida." But the demand of the market had changed, and' cigar-makers now requiredto baccolTresembling the Cuban varieties for the " fillers " of their products and leaf of the Sumatra type for the wrappers. In 1884-5 some of the planters had obtained seed from Cuba and the tobacco grown from the seed was sent to the dealers at New York, who made it into cigars. The quality of the cigars was so satisfactory that experts were at once sent to Florida to advise as to the possibility of extending the cultivation of Cuban tobacco, and their reports were so favourable, that large areas were at once planted in Gadsden County, an example which was quickly followed in all parts of the State. It was not long before serious attempts were* also made to produce the Sumatra wrapper leaf, and seeds were imported from the East. The methods of cultivation and curing adopted in Sumatra were carefully studied, and especially good results have been obtained by growing the plants under artificial shade. For the past twenty years Florida has been steadily regaining her reputation as a producer of first-class tobaccos, and at the present day cigars manufactured from Florida- grown Cuban and Sumatran leaf are among the best obtainable. In the early years of the tobacco trade the varieties in almost universal demand were the dark export types of Virginian tobaccos, and the light pipe types of Maryland leaf, and at the beginning of last century these were practically the only tobaccos cultivated by the American colonists. About 1820, however, a considerable demand arose for stronger coloured tobaccos, and to meet it artificial heat was employed in the curing processes. The present de- mand for light yellow tobacco first arose during the latter half of the century, probably the first crop of lemon-yellow leaf being raised in North Carolina in 1852. The well-known " Mahogany A tobacco-cutting machine 218 The World's Commercial Products manufacturing," " Burley," and " Perique '* types of tobaccos have also been evolved during the last fifty or sixty years. At the present day the principal tobacco-producing States of America are Kentucky (with a crop in 1905 worth sixteen million dollars), North Carolina (seven and a quarter millions), Virginia (six millions), Wisconsin (five and a quarter millions), Ohio (four and a quarter millions), Connecticut (four millions), Tennessee and Pennsylvania (two millions each), and a half millions), one-tenth millions). Massachusetts (one Maryland (one and New York, Indiana, CUTTING CIGARETTE TOBACCO Arkansas, Illinois, and some other States produce less than a million dollars' worth each. The enormous extent of the industry in the United States may be judged from the following figures indicating the production of tobacco since 1800 : — Year.

The figures of the latter table are obtained from the planters and the discrepancy is due to the fact that after being sold to the dealers the leaf is subjected to a " fermentation " process, during which it loses from fifteen to twenty per cent, of its weight. One of the most important factors affecting the successful production of good tobacco is climate, and it is only in the presence of sufficient warmth and moisture that the aromatic principles, upon which depend to so large an extent the quality of the tobacco, can be fully developed in the- plant. There can be little doubt that the most famous tobaccos of the world, e.g. the Cuban, Turkish, and Persian varieties, owe their peculiarities largely to the climate in which they are grown, and the more closely the climate of a proposed new tobacco-growing district resembles that of some recognised tobacco country, the more likely will it be capable of growing a good leaf. Allowing climate, therefore, the premier position of importance in tobacco culture, we find that the character of the soil also affects to a great extent the quality of the product. ' The plant thrives best in a light sandy loam, rich in decaying vegetable matter or manures. As is so often 'the case, the importance of the manures depends not so much upon the amount of actual plant food rendered available by its decomposition, but upon the effect it has in keeping the soil in a well aerated, " loose " condition. So long as the soil is in a good physical condition its chemical composition is of secondary importance, for by Tobacco 219 judicious manuring tobacco is often grown upon comparatively poor soils. The especial require- ments of the tobacco plant with regard to soil constituents are potash and lime, and it is frequently necessary to supply these constituents to the field. in the shape of manures. Ordinary stable manure is one of the best fertilisers where a large coarse leaf is required, but it, has been found by repeated experiment that the best burning tobaccos are produced when the manure takes the form of carbonate of potash. , In the United States the field selected is ploughed in the autumn, a method .which, allows of the destruction of many of the larvae of all kinds as well as producing a good tilth. In the spring the land is again ploughed, the manures added, and then two or three weeks before planting laid out in ridges about three feet apart. Meanwhile the tobacco seedlings have been, raised in a special seed-bed or nursery, which has been prepared with great care. The nursery plot is selected with a southern aspect if possible, and subjected to a process of " burning " — bushes, timber, etc., being laid upon the ground and ignited in such a way as .to burn slowly in order that the earth may be thoroughly baked by the heat. The object, of this process is chiefly to destroy the larvae of insects hibernating in the soil. After the bed has been burned and had time to cool down, the baked earth is broken with a hoe until it is reduced to a fine porous condition. Manure is then applied, often in the form of guano, and, when this has been thoroughly incorporated, the bed is ready for sowing. Tobacco seed is extremely small, an ounce containing between 300,000 to 400,000 seeds, and there are two special difficulties which have to be met by the planter. In the first case, a large percentage of the seeds will not sprout, and hence it is necessary to sow a great deal more than is required. Secondly, the seed coat is excessively hard and resistent to the vivifying action of moisture, and it is not an uncommon practice to bruise the seeds by gently rubbing them with fine emery. The seed is mixed with fine ashes or earth, and then sown evenly over the surface of the bed, which is gently beaten down to retain the seed in the soil ; it is most important, however, that the seed should not be buried too deeply in the soil or it will not sprout. When about four or six inches high the seedlings are transplanted in the field along the ridges at regular intervals of two or three feet. The operation is often carried out by hand, but transplanting with machines is now very generally practised in the northern cigar- tobacco States. The machine, which is drawn by two horses, makes the hole before planting, sets the plants, and firmly presses the earth round them. By its use a man and two boys can plant from two to six acres per day. During the growth of plants the soil is kept constantly broken with a horse cultivator or by hoeing, and great care is taken to keep down weeds. As soon as the flower buds begin to appear a most important operation must be commenced. The production of flowers and seed results in a deterioration of the quality of the leaf, and hence, unless the plants are being grown for seed, the buds are picked off by hand. At the same time certain of the leaves are removed from the plant, the number depending upon the judgment of the cultivator ; the whole process is known as "topping." The young shoots or "suckers" in the axils of the leaves are also removed. In due course the leaves begin to ripen, their colour changing to lighter shades of green and yellow, and yellow spots also appear ; at this stage the leaves are richest in the nicotine, acids, and nitrogenous compounds which are necessary for a good tobacco. The leaves PACKING TURKISH TOBACCO 220 The World's Commercial Products A CIGARETTE-TOBACCO EXPERT do not all ripen at the same time, the lower ones ripening first, and it is owing to this fact that we have two methods of harvesting. The commoner method is to cut the whole plant down as soon as the middle leaves are sufficiently ripe, and, after they have wilted, to cart them to the curing barn. For the production of the finer grades of cigar leaf, however, and also for much of the Bright Leaf tobacco, the leaves are picked or " primed " one, by one as they become ripe. They are then placed in baskets and at once carted to the curing barn. When the "stalk-cutting" system is adopted, the stems are strung on to a "curing stick" about four feet long, which is thrust through the ends of the stems, or the stems are split in half from the top nearly to the base and then placed astride the sticks ; and in this condition they are hauled to the curing barn. In the case of the primed leaves the latter are threaded on to a string when they arrive at the barn, and then tied to sticks upon which they hang during the curing process. Within recent years a great deal of attention has been paid to the cultivation of the more valuable classes of tobacco under artificial shade. The method originated in Florida, where it was found that Sumatra tobacco, when grown under the shade of trees, produced a more satisfactory leaf. Artificial shading of the fields was then tried, posts being erected at regular intervals and. arranged to support light wooden laths above. From Florida the idea extended to Connecticut,, and now the practice is adopted in Cuba and Porto Rico. The shading is generally.: obtained by the sub- stitution of a cotton cloth instead of wooden laths. The results are very striking ; the yield of leaf is greatly increased largely owing to the regularity of temperature and humidity, and also to the fact that these two factors are maintained more or less constant during the night. The plants are also protected from the effects of the weather, and that the method is a success is proved* by the enormous profits of the planters who have adopted it. The tobacco plant is subject to the attacks of many insect and fungus pests, and space does not permit of more than a brief reference to the more important. The very young plants are attacked by " cutworms," which eat through the A TURKISH PIPE-MAKER S WORKSHOP Tobacco ferments, whilst others incline, to the belief that it arises from insufficient nutrition. This question, however, is far from being settled. The Curing Process The curing process is one which must be very carefully carried out, for a good quality tobacco may be ruined by a lack of skill at this stage. The curing is not merely a drying process, but the exact chemical changes which take place are. very im- perfectly known. It appears tolerably certain, however, that the ferments or " enzymes," which, during the sub- sequent "fermentation" of the leaf, give rise to chemical changes which develop' the aroma of the finished tobacco, are formed during the curing process ; and it follows, therefore, that unless the curing is carried out with great care, the fermentation can- not be of a satisfactory character. In the case of certain tobaccos, such as the popular bright yellow varieties, aroma is not so much sought after as lightness of colour, and, in the preparation of these tobaccos, the curing is effected at such a high temperature as to destroy practically all the en- zymes, so that there is but little fermentation in the slender stalks. The leaves are de- voured by "horn worms," which are so called on ac- count of a prominent horn attached to the posterior end of, the body, and other caterpil- lars (Heliothis armiger) de- stroy the terminal bud of the plant. The latter pest is an object worthy of particular notice, since it is the same which, under the name of the " cotton boll-worm," causes such terrible losses to cotton planters These and many other insect pests jj cause considerable trouble to the to- bacco grower, but he has a valuable remedy to hand in an arsenical com- pound known as Paris Green, which is sprayed or dusted over the plants affected, and is fairly effective in destroying the parasites. There are also many fungal dis- eases, both of the living plant and also of the cured tobacco. One of the most important, which has caused enormous damage, is known as the " mosaic disease," since it causes the leaves to present a mosaic appearance as a result of irregular light and dark patches on the living leaves. This disease has been shown to be infectious, and is carried through the fields by the fingers of work- men who " top " the plants by nipping the buds (see above). The disease has been attributed to various causes. Some believe that it is the result of bacteria and poisonous subsequent process. On the other hand, it is most essential that cigar leaf should possess as fine an aroma as possible, and hence to allow of this being per- fected during fermentation, the curing must be A BRIDAL PIPE FROM HOLLAND 222 The World's Commercial Products SORTING TURKISH CIGARETTE TOBACCO performed with great care to allow of the full development of the enzjories. The harvested leaves, then, either on the stalks or picked separately and strung on strings, are brought to the curing barn, where they are placed on sticks, sup- ported by cross-beams in the upper part of the barn. There are several methods of curing. The method em- ployed for the production of the greater part of the tobacco for Europe is " fire cured." By this method the stalks are allowed to hang for four or five days until the leaves become a rich yellow colour, when small fires are lighted on the floor of the barn. The temperature is not allowed to rise above 90°, and then during about a week it is gradually increased to 150°, when the fires are allowed to burn out. The leaves are not yet dry, however, and the fires are again lighted and the process repeated until the drying is complete. The tobacco is then stripped from the stalk and the leaves, after being sorted into grades, are neatly tied into bundles or " hands," containing from six to twenty leaves. The hands are made into piles and covered with canvas. " Flue curing " is adopted for producing the bright yellow tobacco, and great skill in regulating the temperature is necessary. In this method the fires are lighted outside the barn and the heat carried through the building by large air-pipes, so that the smoke and fumes do not come into contact with the leaves. In the first stage the temperature is maintained at about 90° ; the leaves turn a fine yellow colour, and enzymes are formed. Then the temperature is raised to 120°, which " fixes " the colour, and at the same time kills the enzymes, thus allowing of but little subsequent fermentation. The leaves are then finally dried at 135°, when they are graded and stored in bulk. From the nature of the curing it is obvious that this class of tobacco is incapable of undergoing a regular fermentation process as in the case of ' other tobaccos, since the enzymes are destroyed. It is practically ready for the manufacturers, as soon as it leaves the curing barn, though, like all tobaccos, it improves with age. "Air curing" is resorted to for cigar leaf and some varieties of smoking tobacco. The leaves are hung in well- ventilated barns for as long as six weeks, and the process depends upon the satisfactory regulation of the temperature by means of the numerous ventilators. " Sun curing," in the open air, is now seldom employed. The fermentation process is usually not. carried out by the planter but by the leaf dealers. In a very commonly adopted method a quantity -of leaf weighing from two to three hundred pounds is packed in a wooden case, and subjected to a considerable pressure by means of levers or screws. By this means the air is excluded from the leaf, but the moisture and juices resulting from the pressure escape through openings in the sides of the case. ■ ■ ■ ' ' ; " Fermentation Tlfe fermentation is allowed to go on at a constant temperature for several weeks, when the leaf is ready for shipment to the manufacturer. Within recent years the system known Tobacco 223 as " bulk fermentation " is largely adopted. By this process enormous quantities of leaf are treated at one time, the amount varying from three to thirty thousand pounds according to the variety of tobacco required, the lighter sorts being fermented in smaller quantities. The fermentation is carried out in large rooms in which the temperature and degree of atmospheric moisture can be very carefully regulated. The leaves are piled regularly in huge "bulks," and, as soon as the temperature of the mass rises -sufficiently, the bulk is pulled to pieces and re-built, with the outside leaves of the first bulk at the centre. This process is repeated two or three times, with the object of rendering the fermentation uniform. The causes- of the changes which take place during the fermentation are by no means fully understood. For. a long time there has been much dispute as to whether the changes are due to bacteria or to the development of special ferments in the leaf. The balance of opinion is in favour of the view that during the preliminary drying or curing certain ferments or enzymes are developed in the leaf, which have the power of causing the contents of the leaf cells to combine with the oxygen of the air. When fermentation is allowed to take place, these ferments become very active, and the. cell contents, rapidly becoming oxidised, are decomposed into simpler substances which afford to the tobacco its valuable aromatic qualities. The nicotine of the leaf is quite unaffected, but the sugars and nitrates are destroyed, and the organic acids diminish in quantity. The bacteria theory once had many supporters, and it was announced that not only had the bacteria been isolated, but that different types of tobacco acquired their characteristic aromas as a result of the activities of distinct species of bacteria ; and it was even stated that it was only necessary to " inoculate " an inferior tobacco during fermentation with the special bacterium of a high-grade leaf to obtain all the aromatic qualities of the latter. Unfortunately — or the reverse — practical trials afforded no support to this contention. When the fermentation is completed, and the whole process occupies three or four months, the leaves are very carefully graded and packed into bales, cases, or hogsheads for shipment to the manufacturer. The tobacco, however, is not fit for consumption until it has " aged." The period of ageing depends upon the class of tobacco, fermented leaf requiring a shorter period than ordinary unfermented tobacco for smoking, which requires from two to four years. The ageing softens and mellows the flavour, and is essentially a slow fermentation process. The famous Perique tobacco is produced in one spot in Louisiana, viz., Grand Points, and, in spite of its world-wide reputation, the quantity grown is comparatively small. The greatest care is taken in the cultivation, and it is desirable that the ripening should take place under damp atmospheric conditions, which results in the formation in the leaves of large quantities of rich gummy juice. The peculiar characters of the tobacco, however, are due no doubt to the peculiar methods of fermentation. The dried leaves are stripped from the stalk, made into small rolls, and then placed in a box and subjected to enormous pressure applied by means of levers. The pressure is removed every day and the leaves allowed to absorb the expressed juice making Turkish regie cigarettes by machinery 224 The World's Commercial Products MAKING CIGARETTES BY HAND which has become oxidised. It is no doubt due to the pressure and absorption of these oxidised juices that we have developed the unique flavour and aroma of Perique tobacco. Manufacture The fully-aged tobacco reaches the hands of the manufacturer to be converted into the many varieties, brands and mixtures which are familiar to everyone. Most of the leaf reaching this country is " stripped," i.e., deprived of the stalk and mid-rib, but if intended for the manufacture of " bird's eye," the mid-rib is retained, the " eyes " of the tobacco being merely thin slices of the stalk. The manufacture of ordinary smoking mixtures is comparatively simple. The leaves are mixed according to the formulas of the firm, and afterwards damped. They are then transferred to the machine, where they are pressed into a light cake, which is finely cut up by what is essentially a chaff cutter. In the damping stage it is a common practice to flavour the leaf with various substances, sugar, liquorice, and certain aromatic substances being employed ; further, chemicals, notably saltpetre, are also added to improve the burning qualities of the tobacco. The shredded tobacco is then dried or " roasted " on heated slabs or in special machinery, when it is ready for packing. " Roll " or "twist " is made by spinning the leaves by machinery in a manner very similar to that adopted in rope-making. The core of the twist is composed of broken leaf, but the covers are obtained from complete leaf. The material is fed into the machine which converts it into a cord of uniform thickness. "Cake" tobacco, as its name would indicate, is prepared by subjecting a " filling " between covering leaves to considerable pressure, the filling being packed into moulds. Cigars are composed of two parts, a core formed of pieces of leaf placed longitudinally and known as " fillers," and a covering formed of perfect leaf called the " wrapper." The manufacture was formerly carried out almost entirely by hand, but now special machines are used in nearly all cases. Until within the last few years the wrapper was largely composed of Connecticut leaf, but its use was found to be wasteful. At the present time it may be said OF CAUFQg* TOBACCO Tobacco 225 MAKING CIGARS that for cigar manufacture what is required is a " filler " of Cuban tobaccos and a wrapper of Sumatra leaf. Cigarettes were originally en- tirely prepared by the smoker himself, but their consumption has assumed such gigantic proportions that all the vended brands are made by machinery, the structure of which essen- tially resembles that of the small hand-machines in com- mon use. The machines cut the paper and gum its edge, measure out the right weight of tobacco, wrap it up in the paper which is automatically sealed, trim the ends of the cigarettes, and pack them in boxes ! Snuff is largely manufactured from the scraps and waste resulting from the preparation of mixtures and cigars. The fragments are chopped very fine, placed in heaps in warm, damp cellars, and then flavoured with certain substances such as liquorice, tonka beans, deer-tongue leaves, and various perfumes, the nature of which are trade secrets. The mass is allowed to ferment for several weeks, and then dried and finally ground to powder. TOBACCO IN CUBA In Cuba tobacco cultivation is second only in importance to the sugar industry, and no fewer than 80,000 people are regularly employed. In the early part of the eighteenth century the tobacco trade was a monopoly of the Spanish Crown, with a royal office and warehouse in Havana, and branches in Santiago, Trinidad, Bayamo, and Remedios, where the planters could store their tobacco, receiving such prices as might be established by the Crown for each parti- cular crop. Later, the monopoly was sold to private individuals, but in 1760 it was again taken over by the Crown, and it was not until 1817 that the trade and cultivation of tobacco were declared free on payment of a tax by each planter, equivalent to one-twentieth of the production. Since that date the taxes have varied according to circumstances, but usually they have been very high. There is no reliable information as to the amount of tobacco produced in Cuba in the early days, owing to the enormous smuggling which went on. From such data as are available, however, it appears that during the eighteenth century the annual export was probably not less than 20,000,000 lb., and it is certain that during the periods of Crown monopoly the amount was less than during the period of private monopoly ; when the monopoly was completely abolished, the production immediately increased. Coming to more recent times, it appears that the approximate production in 1894-5 was over 62,000,000 lb. of leaf, or 560,000 bales valued at more than £4,000,000. In 1904 the production was 416,000 bales. More than half of the total amount raised is exported in the leaf, and the remainder, about forty per cent., is used in the manufacture of cigars and cigarettes. Nearly one-half of the export is to the United States. Tobacco is raised as an article of commerce in but four of the six provinces of Cuba, though there is no reason why the crop should not be raised in the other two. To the trade the tobacco of Pinar del Rio is known as " Vuelta Abajo," that of Havana as " Partido " and " Semi Vuelta," that of Santa Clara as " Las Villas " or " Remedios " leaf, while the leaf of Santiago is known as " Oriente." 16-C.P 226 The World's Commercial Products . -The quality of Cuban tobacco is world-renowned, more especially that known as the Vuelta Abajo, which is used in the manufacture of some of the finest cigars in the market. Innumerable attempts have been made in other districts of Cuba and in other countries to produce this variety, but all have signally failed, and the secret of its superiority remains unsolved. The Sierra de los Organos, a range of moun- tains running along the entire length of the province of Pinar del Rio, is no doubt a potent factor, since it breaks the high winds which do so much damage to the plants else- where. Various other causes have been suggested, and probably they all contribute to the .conditions which produce this excellent tobacco. To what its superiority is especially due will probably be known when the soils on which it has been cultivated for so long have been carefully analysed and compared, and when the chemical changes of the curing and fermentation processes are better understood. SORTING CIGARS TOBACCO IN SUMATRA As has been mentioned above, Sumatra tobacco is especially valued by manufacturers as a wrapper for cigars on account of the fine quality and extreme thinness of the leaf. It is stated that' there are no fewer than two hundred leaves to the pound, and one pound is sufficient for the wrappers of five hundred cigars. Apart from the thinness of the leaf, much of the value of the Sumatra tobacco is dependent upon the peculiar qualities of the soil, and more especially- upon -the • infinite care that is . taken throughout the whole period of its production. A brief account' of T.tHe industry will therefore not be without interest. Up to 1862 a tobacco of very good quality had foeen produced in the neighbouring island of- "Jaya, 'and 'the cultivation had' been one of considerable commercial success. About this time, -n'Ow'ever,- prices fell; afid^the planters began to make enquiries as to suitable country for. -raising a' -grade -of tobacco equal in quality to the superior varieties which were driving them from' the, market. Following the advice of an Arab trader, a Dutch planter visited.Delf in the east .coast of- Sumatra, and. was so impressed with the local conditions that in '1864 a Rotterdam company started a plantation' in the neighbourhood and obtained a crop of sbrrie fifty bales. The '.superior- quality of the tobacco attracted the attention of experts to sugIC ah extent that five years later a powerful Dutch syndicate decided to raise tobacco in Sumatra on a large scale. Many companies and private individuals soon followed this lead, and in 'the tobacco district at ' the- present; day" there are nearly forty registered companies arid as -many private -planters.- The 'magnitude of the industry may be gauged from the fact that some companies employ as many as 16,000 coolies, with a staff of white experts num- bering Upwards of- two ^hundred. The fact that the- dividends have been known to reach seventy-fiW:per cent, is* suffifcient proof of the commercial success of the undertakings. < T-he^tobacco district of >'Sumatrav borders on the Straits of Malacca, and extends as a belt forty miles wide and five or ten miles back from the coast. The climate is naturally a tropical Tobacco' 227 one, and the soils are mostly volcanic in origin, the'finest tobaccos. being*raised on those resem- bling clay or silt in texture. The land is not purchased freehold by the planters, as is so often the case in tropical agriculture, but is leased from the Sultan for a period of seventy-five years under the sanction of the Dutch Government. By far the greater part of the labour is per- formed by Chinese coolies imported directly from China, and there can be little doubt that but for the yellow labour the successful cultivation of tobacco in Sumatra would be impossible. The Chinese are most industrious workers, and stand the exacting climate well ; they very quickly learn their new duties, for it is stated that the imported coolie has to be taught from the beginning, since he has no previous knowledge of tobacco" cultivation. TOBACCO IN THE PHILIPPINES The soil and climate of the Philippines are peculiarly well suited to the cultivation of tobacco, and next to the finest qualities\of the Cuban and Turkish tobaccos, the product of these islands is considered the finest in the world. The famous Manila cheroots enjoy a universal reputation for good quality'. The product of the Cayagan province is perhaps the finest, and the high quality of the tobacco is usually ascribed to the peculiarities of the soil, which consists of alluvial deposits annually brought down by the rivers. Under the somewhat severe terms of the late Spanish monopoly, the industry showed signs of deterioration, but it is probable that with the removal of these restrictions a revival may take place-. TOBACCO IN THE BRITISH EMPIRE India and Ceylon Tobacco is said to have first been introduced into India by the Portuguese in the early years of the seventeenth century. Since that time several attempts have been made to extend and improve the tobacco industry of British India, and at the present day certain Indian tobaccos and cigars have an established reputation in England. In 1829 samples of Maryland and Virginia seed were sent to India by the direction of the East India Company, and the quality of the leaf produced was regarded as equal to some of the best West Indian varieties. Much of the tobacco, however, was of comparatively inferior quality, and although acceptable to the natives, was quite unsuited to Western tastes. Nevertheless, the experiments had shown that an article of good quality could be pro- duced in India provided the best sorts of seed were used and proper methods of cul- tivation and preparation adopted. The Government therefore, in 1876, established an experimental farm of eight hundred acres at Gha- zipur, on the Ganges, and employed a Virginia planter to superintend the curing of the leaf. Ghazipur tobacco is now recognised as one of the best raised in India. Tobacco for local con- sumption is raised in small patches in most parts of India, but from a commer- cial point of view the chief PACKING CIGARETTES INTO BOXES 228 The World's Commercial Products districts concerned are Bombay, Madras, and the Punjab. The plantations and factories are often man- aged by American experts, and most varieties of the plant, including the Persian " Shiraz " tobacco, have been experimented with. In Madras some of the most celebrated of its to- baccos are grown in the Northern Circars, and in the deltas of the Krishna and Godavery rivers. The famous Dindigul brand is raised in plantations which are managed upon the most modern lines, and the cheroots of Trichinopoly are well known. •The total area under cultivation in. India in 1905 was upwards of 1,000,000 acres, and the value of the export for the same year was £138,700. Considerable quantities of tobacco are also grown in Ceylon, where it is used for local consumption by the natives and for export to India. The quality of the tobacco would be quite unsuitable for the Western market. By permission of Messrs. Gallaher SPINNING ROOM — GALLAHER's FACTORY British North Borneo In other parts of the British Empire the cultivation of tobacco has met with varying measures of success. The industry is of considerable importance in British North Borneo, where in 1883 the first tobacco-planting company, under the name of the Chinese Sabah Com- pany, started a tobacco plantation at Sandakan Bay. Tobacco had long been known to exist in Borneo, but it was the remarkable success of the plantations in the neighbouring islands of Sumatra and Java which first drew attention to the possibilities of Borneo as a tobacco- producing country. Samples of the product were sent to the Indian and Colonial Exhibition of 1886, and very favourable opinions were expressed by the brokers, who, however, pointed out the necessity for adopting improved methods in the drying and fermenting processes. In later years great advances were made in producing an article of good quality, and Borneo cigars and tobacco soon became well known in England. The leaf grown is chiefly intended as wrappers for cigars. Planting is carried out in April and May, and in seventy days the leaves are gathered, so that only three months elapse from the time the seeds are put in the nursery-bed until the gathering of the crop. At the present day there are three large tobacco companies in British North Borneo, the survivors of a much larger number which existed a few years ago. Much competition has been experienced at the hands of the Sumatra planters witmtheir famous leaf, and although tobacco is one of the most important planting industries of the country, it at present shows no signs of immediate expansion. ■ Jamaica ' In Jamaica the cultivation of tobacco has lately received much attention. The soil, climate, and general- conditions are very favourable in many parts of the island, and the area Tobacco 229 at present under tobacco is about four hundred acres. ' The tobacco trade has progressed very satisfactorily during the past eleven years. Jamaica cigars and cigarettes, which are manu- factured at Kingston, have gained a very enviable reputation in the market, and' the industry may now be considered to be well established. In the opinion of many experts, Jamaica cigars are the finest produced in the British Empire. The exports in 1904-5 were valued at £22,408, as compared with a Value of £19,567 in the preceding year, and these figures are exclusive of the locally grown tobacco consumed in the island. Africa - Several of the British African colonies have long grown tobacco, and some of the newer countries are making serious attempts to produce a marketable article ; but up to the present comparatively little has been done, except in British Central Africa, the tobacco of which has a good reputation. .:- . • . . The British South Africa Company is paying special attention to tobacco in Rhodesia, and has called in the aid of the highest expert ' advice in relation to its cultivation and preparation. The different varieties of soil found in the country are capable of growing light cigarette tobacco, cigar leaf, and heavy smoking tobacco,- — all of excellent quality. Cigarettes made from Rhodesian-grown Turkish, tobacco have been on sale in London for the past two years, and of their high quality there can be little difference of opinion. The possibilities of successful tobacco culture in the Transvaal and the Orange River Colony are considerable, and the Government has been sufficiently alive to this fact to engage the services of one of the most prominent tobacco experts in order that the farmers may become acquainted with the best methods of cultivation and preparation. Australasia Several attempts have been made in Australia to establish a tobacco industry, but the net result is comparatively small. In Queensland the crop is grown in the south, but the area planted is not much more than five hundred acres. The tobacco acreage in New South Wales is also small in spite of the fact that in many parts of the State. the climate and soil are well suited to the plant. In Victoria there is a small area under tobacco, but at one time the crop was much more extensively grown. New Zealand has also at- tempted tobacco-growing, but the cultivation is now abandoned. The United Kingdom In order to protect the growing industry in Vir- ginia, an Act was passed in the reign of Charles II forbidding the cultivation of tobacco in England ; and since that time the culti- vation has been prohibited under heavy penalties, chiefly for fiscal reasons. From time to time, how- ever, the Government has permitted experimental By permission of Messrs. GallaHer CORNER OF LEAF ROOM- -GALLAHER S FACTORY 230 The World's Commercial Products cultivation. In 1822 the .restrictions in -the case .oi Ireland were removed, and at the present day tobacco , cultivation is allowed in the sister' isle. In,1886 experiments were conducted in England under. .certain restrictions, and several agriculturists, in Norfolk, Kent, and, other counties. grew the plant with such success as to definitely establish the. possibility of growing tobacco in -England. as a commercial crop. : Permission to continue the experiment, however, was withdrawn, and a letter published to the Times of October 8th, 1906, from the Board of Agriculture and Fisheries, shows that there is practically no chance of the cultivation being again permitted. TOBACCO FACTORIES The enormous strides which have characterised the preparation and the manufacture of the various commercial products during the 'past quarter of a century have been as marked in the tobacco industry as in arty other. As is well known, the cacao or cocoa trade is most closely associated with names which have, a world-wide renown, and the same thing is becoming triie'of /the tobacco trade. •''. It is impossible to enter into full details' as to the different firms which have become identified with the trade,, or to give "any complete account of the methods of manufacture adopted by them. > There are, however, two illustrations inserted in the text which show two of the rooms of- the great factory :of "Messrs.

The export factory, which adjoins the main factory in -Belfast,'- is perfectly equipped, and- the machinery is capable of producing every- class of tobacco which can be demanded by the trade in any quarter of the world: It is interesting to note that the whole of this vast business has been built up by one indi- vidual, Mr. Thomas Gallaher, and his enterprise and energy have earned for him the title of the " Tobacco King." THE GRAPE-VINE The history of the grape may be traced back to very ancient times, to ages, indeed, of which we have no written record. Seeds of the plant have been found in the Lake-dwellings of Castione, near Parma, which date from the Bronze Age, in the pre-historic settlement of Lake Varese, and in the Lake- dwellings of Wangen, in Swit- zerland. Of the cultivation of the vine at these remote periods we have no certain knowledge, but it is probable that in Egypt the grape was cultivated and wine made nearly six thousand years ago. The Bible affords evidence of the early use of wine among the Semitic peoples, and its use among the Phoenicians, Greeks, and an Australian vixeyard ■ Romans is well known. The Grape- Vine 231 AN AMERICAN VINE GROWING IN SICILY The vine (Vitis vinifera) belongs to the natural order Vitaceae, a family which includes the Virginia creeper, and grows wild in the temperate regions of western Asia, southern Europe, Algeria, and Morocco. Whether these countries are the true home of the plant is a point which is open to discussion, but the majority of botanists are of opinion that the vine may be regarded as truly indigenous to the Trans-Caucasian provinces of Russia, whence the seeds have been widely disseminated by birds and by the agency of man. ... . ■ Knowledge of the principles of viticulture and the manufacture of wine spread but slowly from the home of the industry in western Asia, a, fact which is to be explained; largely as a result of the inefficient methods of transport existing at the time which, pre vented wine. being carried any great distance without deterioration. Greece and Italy were; the first countries to copy the methods of the Eastern, wine-growers, and, under the Greeks, viticulture, made great strides, the wines of Candia and Smyrna being largely exported. to-the Romans.. Gradually the cultivation of the grape spread over the whole of central Europe from the Mediterranean to the plains of Germany, from Spain , to Great Britain, and from, thence. the cultivation was carried during the Middle Ages to the fertile lands of the New : World.; ■-..'• ■ At the present day the finest vineyards are still tx> be. found in Europe,, and the wines of France, Italy, Germany, Spain, and Portugal are admittedly unsurpassed by ; any. in thfe, world. Each country, and indeed each district, has its characteristic wine, and the products of the above countries are as distinct from' each ■ other , as they are from .those of Greece, Turkey, Roumania, and Switzerland. In the New World extensive vineyards are 'to be found -in Chili, Peru, Bolivia, Uruguay, and other parts of South America, and in the United States great 232 The World's Commercial Products wine-growing districts exist in Florida, Virginia, and California. In spite, however, of the extent of the cultivation in the New World, the wines do not equal those of Europe, which stand unrivalled. The wine-making countries of Africa are limited to Algeria and Tunis, where the industry is one of considerable importance, and to Cape Colony, whose wines are now in part regaining something of their former popularity. In the southern hemisphere viticulture has made great strides in several of the Australian states, and the wines of these countries have • an established reputation in the world's markets. THE VINE Having thus briefly outlined the history and present condition of the vine-growing industry, we will turn our attention to a consideration of the plant itself, and to the methods of cultivation and manufacture which have for their object the production of the wines of our tables. The majority of people in this country would describe the vine as a climbing plant, with large, deeply lobed leaves, and bearing bunches of round berries, either green or blue-black in colour. While this description would hold good for a common variety of the vine, it would be quite inaccurate for many others, for "the vine is a very variable plant, and there are innu- merable varieties cultivated in different parts of the world. While some vines are climbers, others may be trained as hedge plants, others may be induced to form arbours, but the most variable characters of the plant are to be found in its leaves. These are -frequently deeply lobed, of a brilliant green colour, and with well- marked veins and downy coating on their under sur- ' pumping water -FOR IRRIGATION in Portugal' faces. The greatest Variation ■ v : '. ■ ■• , . -'"•.' . . '. • . from this type, however, is found in- the' different varieties' of the- plant. The fruits grow in clusters which may be long and pyramidal, or short and dense, and much variation is found in the characters of the -berries, or -grapes themselves.- Some are as large as a plum, as in the American varieties, others are not much larger than a pea, while the differences in colour are known to everyone. In some Gases the pulp is soft, -in 'others firm, and the juice may be either colourless or red. The well-known " bloom " of the common hot-house grape is absent in many varieties. The vine' will yield satisfactory vintages only when grown in a temperate climate, and supplied with a moderate amount of moisture. -Too much water results in an excessive growth of' the leaves and- shoots, and the grapes are watery and acid ; on the Other hand, in a dry climate the fruits -are small and contain toO'large a proportion of sugar to render them of use for1 wine-making. Light is another important factor,- and the cultivator chooses situations for his Vineyards where the plants will not run the risk of- scorching by the sun, nor, on the other hand, be deprived of a generous' supply of its- warmth and light. • Although "the climatic conditions must be very favourable for the grape-vine, the plant is much less -exacting with regard to soils, for it will accommodate itself to most, growing especially yvelh inHhose of a gravelly, chalky;- or stony nature. Nevertheless, a knowledge of the chemical composition and physical condition of the soil is of the utmost importance in viti- culture, since the flavour of the wine depends to a very large extent upon these factors, for under identical atmospheric and climatic conditions we may have wines produced of totally GATHERING THE FRUIT IN PORTUGAL 233 if 234 The World's Commercial Products ' GATHERING THE GRAPES different character, the difference resulting entirely from the variations in the chemical and physical constitu- tion of the soil. Locality, again, has a marked influence on the quality of the wine produced. Vineyards such as those of America, Australia, Algeria, and Tunis, which are chiefly planted in the rich soils of plains, and but indifferently protected from excessive rain and sun, produce large quan- tities of fruit, but of a comparatively poor quality. On the other hand, the fruit from the vineyards of hilly and moun- tainous districts, where the soil may be considerably poorer, as a general rule yields a wine of a much more delicate flavour. The vineyards of valleys, again, have their own special disadvantages, for here the vines may be exposed to excessive moisture and insufficient sunlight, and hence ren- dered more susceptible to disease. In spite of all these difficulties, however, the experience of centuries and the resources of modern science render it possible in many instances for the viticulturist so to modify and ameliorate natural conditions that a good wine is often produced from vineyards which are situated under any but ideal circumstances. Planting a Vineyard The first step in planting a new vineyard is to thoroughly prepare the soil by ploughing or digging, the laborious process of digging being resorted to only when ploughing is impossible owing to the situation of the field. At this stage the soil is often mixed with another of proved quality from a different locality to make up any suspected deficiency, and then the whole field is thoroughly dressed with a slowly decaying manure, such as the refuse of leather or horn. The vines to be planted out are raised either from slips, layers, or seeds. In the former case, which is by far the most common method, a branch which has lost its green colour and has become covered with a thin brown bark, is cut into lengths of about sixteen inches, which are tied up in bundles, and wrapped round with damp moss. They are then planted in the fields directly, or may be placed for a time in a special nursery. " Layering " is another method frequently resorted to.. In this case a branch still attached to the mother plant is bent down to the ground and covered with soil to a depth of about eight to twelve inches, in which it strikes root. After about two' years such a "layer" or "sucker" is sufficiently strong to be separated from the parent plant, and the new vine is then treated in exactly the same way as a slip or cutting. The third method,," viz., raising from seed, is almost entirely restricted to testing new varieties produced by artificial cross-fertilisation. This interesting and delicate operation, which is carried out by experts, consists in the transference of the pollen of one variety of vine of known value io'the stigma of another, which also possesses approved qualities, the object being to psoduce' seed which will give rise to plants combining the characters of the two parents. Improved varieties are also produced by ,the ordinary process of grafting. The method of planting varies considerably with the customs of the people and the extent and shape of the vineyard. Commonly the slips are placed in holes made to a depth of from The Grape-Vine 235 twelve to sixteen inches with a wooden or iron planting-stick. The labourer places his foot on the cross-bar of the planting-stick, pressing the latter into the ground to the required depth, and then plants the cutting in the hole, which is filled up with fine earth and easily assimilated manure. In other vineyards the spade is employed for making the hole, the advantage of this method being that the larger hole allows of more fine earth and manure being placed in the immediate vicinity of the young plant, which forms under these circum- . stances a much more satisfactory root-system. A- third method of trenching is also commonly practised, in which the plants are placed at regular intervals in trenches previously prepared, which are subsequently filled in with the earth from the trench immediately in front. The distances between the vines is in all cases determined by several factors, the. chief of which are the fertility of the soil, the known requirements of the variety planted, and last, but not least, the nature of the implements to be utilised in the subsequent cultivation of the vineyard ; for it is obviously important that if water-carts and ploughs are to be used in the vineyard while the crop is coming to maturity, sufficient room must be left between the rows to allow of such cultivation. Various methods of training the vines are employed in different ■countries. In north and central France the vines are supported by a strong stake of chestnut, and such a method is commonly adopted in Germany and other countries! Perhaps the most important part of the cultivation of the vineyard after the plants are well established consists in scientific pruning and efficient weeding. The pruning is performed by highly trained vine-dressers, who use specially designed scissors for trimming the shoots ; the system of pruning depends to a great extent upon local custom. Weeding generally is •effected by ploughing or sometimes by hoeing, but it is essential that such ploughing should not take place while the vine is in bloom, or the unavoidable shocks given to the plants result in the fruit not being set. In small vineyards the weeding is done by hand, and although the process is long and very fatiguing, since the labourer must use a short hoe, there is little doubt that the plants run less risk of injury than when the plough is used. The Enemies of the Grape- Vine During its growth the grape-vine is exposed to the risk of attack from several destructive •enemies belonging to both the vegetable and animal kingdoms. Some of the pests are so rapid in their onslaught that when once they have obtained a hold on the plant it is quite impossible to check their progress even if the most energetic remedies be resorted to ; on the •other hand, many diseases may be checked and even avoided altogether by the timely and vigorous adop- tion of certain well-known remedial measures. Snails, moths, plant lice, leaf rollers, and numerous •other insects do great damage in the vineyard, and many are the methods which have been adopted by the cultiva- tor to combat their ravages, often with a considerable amount of success. But .great as is the damage done by the above pests, their •effects pale before the rav- ages caused by the dreaded the grape harvest 236 The World's Commercial Products FRUITFUL VINES phylloxera, which has caused, at one time or another, enormous losses in the vineyards of most of the wine-growing countries of the world. Phylloxera vastatrix is an insect belonging to the plant lice family or Aphidae, a group well known for their destructive habits. It is a native of North America, and in Europe first made its appearance in France, appearing later in Italy, Spain, Austria, Germany, and finally in Hungary. Subsequently it caused enor- mous damage in the vineyards of the East, and when the pest again reached the Mediterranean many of the plantations of Algeria were utterly ruined. The Cape of Good Hope was next attacked, and, after nearly ruining the wine industry of the colony, outbreaks occurred in both North and South America. The disease has also appeared in Australia, and practically the only vine-growing country which has hitherto escaped the scourge is Tunis, where stringent measures have systematically been taken to prevent the introduction of the insect. Vines attacked by the phylloxera present a very typical appearance. The plants develop com- paratively few leaves, which are small and quickly lose their colour, becoming yellow or yellowish-brown ; another striking feature is that the edges of the leaves become rolled back. At a later stage the effects of. the disease are noticeable in the grapes themselves, which become arrested in their growth and much wrinkled. If the roots of such a plant are exposed and carefully examined with a lens, the cause of the disease becomes evident. The rootlets are seen to bear numerous firm, yellowish. The Grape- Vine 2&7 PHYLLOXERA. THE WINGED INSECT tubercles, which later become dark and rotten, and on the tubers may be found large numbers of the phyl- loxera itself — minute yellowish-brown creatures, pro- vided with six legs and a strong, tubular proboscis, by means of which they pierce the bark of the root and rob the plant of its sap. These insects, are wingless females, which from March to October lay enormous numbers of eggs which give rise to females exactly similar to themselves. During the summer, however, a second form of insect appears among the root-dwellers, although the eggs from which they are hatched possess no characteristics to distinguish them from the others. The new insect, when mature, is provided with wings, and, after emerging into the air through the soil, flies about the vineyard during the summer and early autumn, feeding upon the juices of the leaves and twigs of the vines. The winged insects or nymphs, which are all females, lay their eggs on the leaves, and in . the next generation we have the appearance of insects of both sexes, male and female, neither of which possess wings. The life of these forms is very short, / . \ and is taken up with producing a new generation of females, also wingless, which are known as the stock- mothers. These latter attack the tissue of the leaves, forming galls on the under surface, where they take, up their abode. We at last complete the com- plicated life history of this pest, for the numerous progeny of the stock-mothers emerge from the galls, and, descending to the roots, become the root-dwelling forms which once more start the vicious cycle. fJ Although the attacks of phylloxera frequently result in the ruin of the vineyard affected, the vigneron is not entirely without remedy. America is the home of the pest, and it seems but just of Nature to provide from the same country the salvation of the afflicted vine-grower. Many of the native vines of America have become immune, as it were, from the attacks of the insect after long ages of susceptibility, and the remedy which has met with the greatest amount of success consists in rooting up and destroying all diseased plants, and planting stocks of the American " phylloxera-resisting " varieties. When once estab- lished, cuttings of the local vines are grafted on to the stocks, so that we have what may be regarded as a composite plant — a plant whose roots are proof against the attacks of the insect, and whose fruit produces a wine which still maintains the local tradition. Diseases due to the attacks of fungi have also caused enormous losses to vine-growers. The most important is undoubtedly that caused by Oidium (Erysiphe) Tuckeri. The disease was first noticed in England near Margate in 1845, and in less than seven years it had spread through all the wine-producing countries of Europe. The fungus appears on the surface of PHYLLOXERA. WINGLESS FEMALE AND EGGS EGGS OF PHYLLOXERA 238 The World's Commercial Products PHYLLOXERA. THE WINGLESS 1 " "FEMALE ' the young vine leaves as a delicate white weft of filaments which send suckers into the leaf cells, absorbing nutriment from them. It rapidly spreads over the surface of the plants and finally attacks the grapes themselves, causing them to become spotted and at last completely withered. The fungus is prop- agated by means of spores which are found in chains on delicate filaments which project from the surface of the plant. In 1892 another means of reproduction was discovered in Europe, but that already described is by far the most im- portant. The most effective means of checking and even preventing this disease has been found to consist in puffing flowers of sulphur on to the plants before the dew has evaporated. " Black rot," caused by the attacks of another fungus, Laestadia (Pkysalospora) Bidwillii, affects all young organs and shoots of the vine. The grapes first show signs of the' disease when about the size of peas, and later they fall off, either singly or in clusters. Black rot is one of the most dreaded of the vine diseases in America, and although it has been observed in France, the fungus has as yet done com- paratively little damage in Europe. Spraying the vine with the solution of copper sulphate (blue vitriol) and lime known as " Bordeaux mixture" is generally recommended as the most effective remedy. " Anthracnose "of the vine, known on the Continent as " brehner," " pech," and " charbon," has also caused great losses. The fungus, Phoma (Sphaceloma) ampelinum, penetrates the leaves, bark and grapes, and kills the tissues. On the leaves and- grapes sunken dark spots occur, and later the spots, when dried up, drop out of the leaves. Spraying with solutions of copper sulphate appears to be the best remedy. Among other -fungi attacking the vine may be mentioned Peronospora viticola, a pest closely allied to that causing the disastrous potato disease ; arid Dematophora necatrix, which causes a very destructive root disease often confused with that resulting from phylloxera. The Harvest When the grapes are ripe the gathering begins, but in some of the hotter districts the grapes are gathered before reaching full ripeness in order that the tartness may preserve the wine. For some liqueurs, on the other hand, it is necessary to have a large amount of sugar and alcohol in the fruit, and hence for these wines the grapes- are gathered when somewhat over- ripe. As soon as the grapes have been picked they are transferred to cellars to await the first processes in the manu- facture of wine. Before dealing with this subject, however, it would be well to mention that no small proportion of vine-growers devote considerable attention to the cultivation of grapes suitable for the table. Spain furnishes supplies of excellent dessert fruit, and the hot-house grapes of England, Belgium, and the Low Countries are world-famous, especially those of England. One of the finest varieties of table grapes is the Chasselas of Fontaine- bleau, which owes its name to the celebrated vine in the Royal Park at Fontainebleau. The PHYLLOXERA. THE WINGLESS . MALE PHYLLOXERA. WINGLESS FORM JUST HATCHED The Grape-Vine 239 fruit is borne in large clusters which, however, contain relatively few golden-green berries, characterised by a very thin skin and a sweet pulp of exquisite flavour. Another variety of grape, known to everyone under the name of " currants," is extensively grown in Greece, and is the object of an enormous trade, the principal centres of the industry being at Patras in Morea and the isle of Tante. - Besides yielding a first- class dessert fruit, grapes are the source of the valu- able raisin and muscatel. Raisins are nothing more than dried grapes, and it might naturally be supposed that wherever the vine is cultivated for wine-making these raisins would be pro- duced. This, however, is not so, for the production of the dried fruit is confined to certain well-marked vine- growing districts, the most important being the country in the neighbourhood of Malaga and Valencia in Spain, whence we respec- tively receive the muscatel and the well-known pudding raisin. Certain districts of Asia Minor produce large quantities of the stoneless sultana raisin, and smaller quantities are exported from Greece. Within recent years a large trade in raisins and muscatels has developed in California, and the decay of the wine industry in South Africa has resulted in the vine-growers turning their, attention to raisin produc- tion. Further, the Austra- lian states are taking their part in the supply of this popular fruit, and at the present time the export of raisins, especially from South Australia, is considerable. Lastly, great quantities of raisins are produced in many districts of Persia, but they are principally consumed locally, largely owing to insufficient means of transport. The method of drying the grapes varies in different countries. In Spain the finest varieties of raisins are produced by partially cutting through the stalks of the bunches which are allowed to hang on the vines, and the drying and curing of the grapes is hastened by a vigorous thinning ROOT-SYSTEM ATTACKED BY PHYLLOXERA 240 The World's Commercial Products -of the leaves to allow of the penetration of the sun. Generally, however, the ripe bunches are cut from the vine, and then placed in the sun on sloping floors until the fruit is sufficiently -cured. In Asia Minor the drying is retarded by sprinkling the bunches with oil, thereby reduc- ing evaporation, and this process is said to preserve the fruit in transit. When dry the fruit is carefully graded, and either packed in fancy boxes, as in the case of muscatels, or else exported iin bulk'. The pick of the market comes to London. (See article on " Fruits.") WINE-MAKING The primary purpose of viticulture, however, is the manufacture of wine. Briefly put, the process consists in allowing the juice of the grapes to ferment under certain conditions, when it undergoes fundamental changes, and is converted into wine, the varieties of which are as numerous as the methods employed in producing them. In the preparation of red wine the grapes are taken into cellars, the temperature of which can be carefully regulated. In former days the next stage was to place the vintage into an enormous bowl and allow the grapes to be pressed by men dancing on them. The obvious objection to such a process has led to the employment of machinery, and in all large wine factories at the present time the grapes are passed between horizontal cylinders which press out the juice without crushing the stones. The expressed juice, or " must," as it is called, is collected in bowls and allowed to ferment, a process which consists essentially of the conversion of the sugar of the grape into alcohol and carbonic acid gas, the change being brought about by a unicellular organism closely allied to the yeast plant. The fermentation is most vigorous at a temperature of about 20° C, and the more favourable the conditions of temperature and the larger the quantity of must, the quicker the process is completed ; depending upon these conditions it may be from twenty-four hours to eight days before the process is completed. At the height of the fermentation the liquor is in a condition of considerable commotion, and if the stalks of the bunches have been left in the bowls the whole mass rises to the surface. Sooner or later, however, the turbulence subsides, the stalks sink to the bottom, and the liquor becomes coloured and acquires an alcoholic flavour ; when the fermentation has completely ceased the first wine or " vin de goutte " is drawn off. The colour and flavour of the wine depends upon the length of time the must is allowed to remain in the bowls, but as soon as the required oondition is reached the wine is transferred to barrels, the lees being kept back by means of a sieve. The lees are not discarded, however, for out of them, by successive pressings, wines of inferior quality are made. These wines are of sharp flavour, and are generally casked separately from the " vin de goutte." There are numerous varieties of red wine, and they are made in all vine-growing countries. The French red wines especially are highly valued, and of their excellence there can be but one opinion. Among the red wines of Burgundy may be cited those of Musigny, Richebourg, Romanee, Chambertin, Corton, Beaune des Hospices, Pommard, Volnay, Alios du Roy, and Clos de Vougeot. The Clos de Vougeot is one of the most highly prized of the products of OIDIUM ATTACKING THE GRAPES The Grape- Vine 241 the beautiful Burgundian vineyards ; its origin can be traced back to a.d. 1110, when the monks of Cipeaux received the vineyards from Hugues le Blanc, lord of Vergy, and cultivating it with infinite care, succeeded in producing a wine which has maintained its reputation for centuries. The wines of Beaujolais such as Macon, Thomis, Fleuric, and Moulin-a-vent are also well known, and the pride of the banks of the Rhone are l'Hermitage, Cote-Rotie, and Chateauneuf-du-Pape. But the French wines, however, which enjoy perhaps the greatest popularity in the land which produces them are the world-famous red wines of Bordeaux, some of the principal varieties of which are Haut Brion, Chateau-Margaux, Chateau-Leoville, Chateau- Lafite, Chateau-Lagrange, Chateau-Larose, Chateau-Millet, Mouton-Rothschild, Chateau-Latour, Branaire, Montrose- Dolfus, Ducru-Beaucailloux, Clos dTssan, St. Estephe, St. Emilion, and Medoc. Although the wines of Bor- deaux have been famous for centuries, it was not until towards the end of the eighteenth century that they became really fashionable, a state of affairs which was largely brought about by the influence of Marshal de Richelieu, who introduced them to the notice of the Parisians. Having thus briefly dealt with red wines and their manufacture, we will turn our attention to the white varieties. White wines are made in a manner quite dis- tinct from that adopted for red wines, but it is a common error to suppose that white wines are made solely from white grapes to the exclusion of purple fruit. It is quite true that many grapes are quite unsuitable for white wines, since their juice is too strongly coloured, but the ' total exclusion of these varieties for white wines is by no means the case. The wines are produced by two distinct methods. In the one case the vintage is thrown into huge bowls or basins and the juice, as soon as it has been pressed out, drawn off and placed into casks, where it is allowed to ferment ; it is very important that the sediment should be abstracted as soon as possible. In the other method the grapes are taken directly to the press and great care is exercised to avoid too great pressure, which would result in the must becoming coloured by the expressed juices of the stalks. In both cases the lees are placed on hurdles and the wine which drips from them is collected and added to that obtained first. It frequently happens that in spite of all precautions to the contrary the must is of too strong a tint, and to effect the decolourisation of the wine it is the practice to treat the must with sulphuric acid or charcoal. Owing to the early extraction of the lees the fermentation of white wines is much slower and less vigorous than in the case of red wines, and to facilitate the process the wines are often transferred to other vessels. The liquor in these vessels is kept at a constant level by the addition of new must, and if the scum which collects at the surface is repeatedly removed we have the production of " sweet " wines ; on the other hand, if the scum is allowed to remain, so that the fermentation may be more complete, " dry " wines are the result. As the " dryness " of a wine depends upon the completeness with which the sugar of the juice is converted into alcohol and carbon dioxide, it follows that to produce the driest wines fermentation should be VINE ATTACKED BY OIDIUM 17— C.P. 242 The World's Commercial Products allowed to go on as long p as possible. Conversely, it should be possible to pro- duce sweet wines by stopping the fermen- tation, and this is effected by the fumes of burning sulphur. There are a great many varieties of white wine, and perhaps the most famous of all is the Rhenish wine known as ia v " Johannisberger," which is grown in Germany. This variety is said to fetch the highest price among white wines, and its reputation has become world-wide. Enormous casks of Johannisberger are lying in the municipal wine cellars of the township of Bremen, the wine being casked and stored in its present position over three centuries ago. This wine, leaf affected with black rot known as " the Rose," is, as one might suppose, the subject of more than one legend, and is offered in hospitality to royalties and persons of distinguished rank who partake in the festivities of the town ; it is also graciously given to the sick. Other Rhenish wines of great repute are Rauenthaler, Liebfraumilch, Marcobrunner, Rudesheimer, Hoheheimer, Kottenlocher, Zetlinger, and Riesling. The white wines of Burgundy are also highly appreciated, and Montrachet is regarded by some as the king of white wines. Meursault-Goutte-d'Or, Chablis Moutonne, Pouilly-Tuisse are also excellent. Among the white wines of Bordeaux, Chateau- Yquem is considered the best, and Chateau-Myrat, Latour-Blanche, Clos St. Marc, and the wines of Sautome, Barsac, and Graves also enjoy a high reputation. Wines known as pale wines are obtained by pressing the sediment a little more than in .the case of the white wines. They possess an agreeable freshness of flavour and are dry, but are liable to turn yellow as soon as they come into contact with the air, a disadvantage which is mitigated by casking as soon as possible. Light red wines are prepared in the same way as the red wines, with the difference that the sediment is not left in the must longer than twenty-four or forty-eight hours at the most. The right moment for its abstraction is when the larger part of the sugar has had time to be transformed into alcohol, as in the case of the dry white wines, without the wine having acquired too much colour. A kind of wine is also prepared from .dried grapes. This is the case especially in France, where about 100,000,000 kilograms of dried grapes are annually imported, chiefly from Greece. •Of these about 4,000,000 hectolitres of wine are prepared, making a wholesome drink, which, however, , is jIqss invigorating. than wine made from fresh grapes. All, wineSj_ whether, red, white or pale, still require a good deal of care after they have been casked. During the second fermentation . the chemical processes are continued and facilitated , by; various means. ; As fermentation always develops heat, the wine takes up more, space. wJrUe ;i.t is. fermenting than when the fermentation has abated. Daily the liquid bepqme% less jn. bulk,, and to, avoid contact with the air, which would turn the wine sour, the •ca^ksT-a^evre^uJ.ariy, filled, f up.; Moreover, the wine in the casks only slowly deposits the im- P^ties ^vhich^t contains,, and. to facilitate, their deposition the wine is drawn off several times eiili^r J^y -siphon^ or^smaU. pumps, mounted on light carriages. This process is repeated three orJiqur^ times at intervals of aiew months. It is never carried out in the hot weather, when the fermentation is most active. The Grape-Vine 243 Notwithstanding these measures adopted for its clarification, the wine contains a good •deal of matter in suspension which must be got rid of. The clarifiers employed for this purpose are isinglass, white of egg, and salt ; blood arid milk are also sometimes used. The action of these clarifiers is purely mechanical : they form a kind of network with narrow meshes at the .surface or in the body of the liquor, which slowly sinks to the bottom and carries all impurities with it. It is then necessary to arrest the fermentatiorr completely. This is accomplished either by the fumes of burning sulphur or, in large establishments, by heating the wine in special vessels to a temperature of 50° to 65° C. All fermentation ceases when the temperature rises above 40°. Champagne is a wine of so universal a reputation that in any account of viticulture and the wine industry it demands special treatment. The wine grown in Champagne was early appreciated by connoisseurs, but its modern reputa- tion dates back for three centuries when Dom Perignon, governor of the abbey of Hautevillers, invented the effervescent liquor, which plays so important a part in our festivities. The manufacture of champagne affords employment to many thousands of people, and the fact that one single house employs more than 3,000 hands concerned in the actual making ■of the wine will afford some idea of the extent of this branch of the wine industry. Champagne is manufactured by special methods which demand great care and skill on the part of the operator. The plants themselves which are to yield the grapes destined for this famous wine are chosen from among the very best, and the fruit is most carefully selected. Just as in the case of ordinary white wines, the vintage is taken at once to the press and the juice resulting from the first pressure is reserved for the preparation of the superior qualities •of champagne. The lees are then cut up and again subjected to pressure, a process which is repeated two or three times, the juice affording the cheaper varieties of the wine. The fermentation processes are carried out in large vessels containing about 200 litres of •clarified must apiece, the most favourable temperature for the operation being between 16° C. and 18° C. When the fermentation is considered to have gone far enough, the must is drawn •off into barrels which have been very carefully cleaned, and later the contents of these barrels are transferred to a gigantic cask where the must is thoroughly mixed by means of a mechanical stirrer. At this stage, should the wine be found to be deficient in alcohol, a quantity of the pure spirit is added and the wine again transferred to casks, where it is clarified by means of the usual agents. When the clarification has reached a certain stage, sugar is added in pre- viously calculated quantities according to the variety of wine desired. The wine is then bottled, corked and wired, and for the next two, three or four years allowed to mature, the bottles being stacked five or six bottles deep. At the end of this period the bottles are taken out and placed on •slanting racks with the necks pointing downwards. In the course of time a sediment collects in the bottom of the bottles, and when later the corks are allowed to "fly •off," all the impurities are expelled from the bottle by the force of the gas gene- rated. This operation is by no means without its dangers, for it frequently happens that the bottles burst, and it behoves the SPRAYING VINES WITH A FUNGICIDE 244 The World's Commercial Products workmen to exercise great caution. The final process con- sists in adding a- small quantity of syrup, the latter being a solution of sugar in old wine, and then the bottles are hermetically sealed, wired, and the cork and neck wrapped round with tinfoil. After labelling, the bottles are again transferred to the cellars, where the- wine acquires its effervescing qualities by the generation of carbon dioxide. As one would naturally 'suppose, the quality of the champagne will vary with the vintage, and it is the practice to reserve quantities of the wine made from a good vintage for the sole purpose of mixing, with the -champagne of less favourable years in order to maintain, to a large extent, the average quality of the wine. There are many varieties of champagne, but some of the most famous are Pommery- Greno, St. Marceaux, G. H. Mumm, Moet, Montebello, Heidsieck, Roederer, Mercier, and Cliquot. GRAPES, ATTACKED BY MILDEW A most important branch of the wine industry is the distillation of alcohol or spirits of wine. One of the chief sources from which alcohol is obtained on a commercial scale is wine, and the distillation of the spirit from wines is confined almost exclusively to France, where the product is largely used in -the preparation of the many kinds of brandy. Wine contains from seven • to j twenty- four per cent, of alcohol, and LEAF OF VINE ATTACKED BY PHYLLOXERA 245 246 The World's Commercial Products in making choice of the wines to be distilled the first point to be considered is the amount of alcohol which they contain, and then the quality of the spirit which they will yield. The first question is decided by direct testing with a test-still, but as regards the quality of the spirit much depends upon the age, purity, and fineness of the wine employed. White wines are to be preferred, and all the best varieties of " cognac " brandy are distilled from these wines. A coarser kind of spirit is prepared from the refuse of the wine-press. This refuse still contains a certain amount of sugar, and fermentation is allowed to take place in vats in which the lees are kept at the bottom by means of heavy sieves. After fermentation, which takes about five days, the clear liquor is drawn off and distilled, producing a spirit of a rough, unpleasant odour and flavour. The actual process of distillation is carried out in large stills, a common form of which consists of a boiler containing a series of con- centric cylinders so: arranged as to effect the separation of the spirituous vapours from the steam. The boiler is heated by a brick furnace, and the vapours condensed by means of an ordinary coil condenser, from which the finished spirit is collected. WAGGON FOR TRANSPORTING THE GRAPES VITICULTURE IN THE BRITISH EMPIRE Cape Colony Having thus briefly considered the principal features of the wine industry in France and other parts of the Continent, it will not be out of place to refer to the present condition of SPREADING CURRANTS TO DRY 247 248 The World's Commercial Products A PRIMITIVE WINE-PRESS viticulture in those parts of the British Empire where experiment has shown that it can be successfully carried on. At the outset it will be well to state that the extent of the Colonial wine industry is at present almost negligible when compared with that of Europe and California, but-1 especially in the .case of the Australian states, the industry may be regarded as being as yet^in'its infancy, and it will, be of interest to consider the degree of success which has attended the efforts -of our brothers across the seas to enter a field of industry which at one time was regarded, with good reason, as being peculiarly European. The wine-producing colonies are Cape Colony and the Federated States of Australia. The output in gallons of these countries for 1904 will be seen from the following table, but although ,the actual amount of wine produced is by no means inconsiderable, it is but a drop in the ocean, being not more than 0'3 per cent, of the world's total production.

It was in 1653 that Van Riebeck, the founder of the first European settlement at the Cape, planted the first vines in Table Valley. The vines were brought from the Rhine vineyards, and since they flourished in their new home, large numbers of plants were brought into the country from Germany and France. Van Riebeck had probably already noted the presence of several species of vine at the Cape, and since it is known that he was a keen observer of Nature, it is highly probable that he early conceived the idea of experimenting in the new country with the vines from Europe. The earliest account of a vintage is in 1659, and it appears that the Dutch took up the new industry with considerable determination, for we find that in 1681 the first brandy was dis- tilled, and six years later the total number of vines planted in the colony was no less than half a million. By 1710 the cultiva- tion had increased enormously, for, in a report furnished to the Dutch East India Company, we find that the vines planted numbered 2,729,300, and that small quan- tities of the wine produced had actually been shipped to Europe and Java. At the time viticulture was the most prominent feature of Cape agriculture, and, relatively speaking, was much more important than at the present day. About a hundred years later the number of vines had increased to considerably over twenty-two millions, and the export of wine reached a total of 21,300 pipes. It will come as a surprise to most people to learn that at about this time (1822) England imported more wine from the Cape than she did from France, the actual figures being 11,211 tuns from our neighbours across the Channel and nearly 19,000 tuns from South Africa. During the last century the cultivation of the vine was extended, but in spite of the increase in the number and extent of the vineyards, the export of wine gradually diminished, and at the present time wine occupies a very low position in the exports of the country. This undesirable state of affairs has been due largely to the disastrous diseases and pests which have attacked the vines from time to time, and on more than one occasion the industry has been on the verge of ruin. In 1858 the destructive fungus oidium attacked the vineyards and threatened to destroy .them,, but its ravages were mitigated and finally checked by the vigorous adoption of the sulphur treatment, and the. crops were restored. In 1885 the dreaded pest phylloxera appeared near Mowbray, and "while at first; it was hoped that the disease could be stamped out by the eradication of all vines^in the- infected areas, it soon became evident that the insect spread too rapidly to cope with its ravages in this way, and the struggle against phylloxera had to be totally abandoned. The vignerons, however, did not despair, but, profiting by the experience, of .the.>, viticulturjsts of Europe, commenced the importation of phylloxera-resisting American; stocks, the use of which- in combating- the pest has been described above. At the present time large nurseries of American vines are established at Constantia, Stellenbosch, and the Paarl. A PORTABLE WINE-PRESS The Grape- Vine 251 To-day the cultivation of the vine at the Cape is carried on almost exclusively in the western part of the colony, where the climate is probably more favourable to the grape than that of any other part of the world. During the spring there is, in these districts, a sufficiency of brilliant sunshine and rain as will cause a vigorous development of the shoots, and towards the summer, although the sun is in its power, the humidity of the atmosphere is sufficient to allow of the further growth of the bunches which in January and February mature under ideal conditions. By far the most important wine-producing districts of the Cape are Paarl and Stellenbosch, and these are followed in order of their importance by Cape, Malmesbury, Caledon, Robertson, Oudtshoorn, Clanwilliam, Swellendam, Prince Albert, Willowmore, and Uitenhage. The viticultural districts of the Western Province may be divided into coast and inland districts, differing from one another in the nature of the soil and climate, and hence also in the method of cultivating the vineyards. The soil in the hilly country of the coast districts is derived from the disintegration of granite, sandstone, clay, and slate, and is so retentive of AN UNDERGROUND WINE CELLAR 252 The World's Commercial Products moisture that irrigation is quite unnecessary. On the other hand, the inland districts possess a calcareous soil which does not retain the water to so great an extent, and it is necessary to irrigate the vineyards two to four times during the season before the grapes will ripen to perfection. The yield, however, of the inland districts is greatly in excess of that of the coast districts, and the quantity of wine produced is on an average more than double. With regard to the quality of the wines produced at the Cape it will be sufficient to add that the grapes grown in the colony are of peculiar suitability for the preparation of sweet wines, ports and liqueurs, but that the light wines produced, although steadily improving in quality, are much inferior to those of Europe, and it will be probably long before they obtain a footing in the European market. The inferiority of these wines is largely due to the fact that the first fermentation which is carried out at a high tempera- ture is very tumultuous, and is all over in from four to eight days. It will be remembered that in Europe the same process occupies a much longer period, a fact which allows of a much less vigorous action and the consequent retention of the volatile substances to which the bouquet of the wine is due. In the Cape wines the volatile compounds are expelled during the rapid and bois- terous fermentation, and consequently they lack the character which delights the heart of the connoisseur. Australia As will be noticed from the figures already given, the principal wine-pro- ducing States of Australia, in order of their importance, are South Australia, Victoria, and New South Wales. Vines were first planted in South Australia between 1840 and 1850, the stocks being obtained from the Botanic Gardens at Sydney, and later from Spain and other parts of Europe. Historically, the most interesting of, the vineyards of the colony are those at Reynella, planted by John Reynell, for it "was here that, in 1846, the first wine vines were cultivated, and the first wine made. The principal wine-growing districts in the State, at the present day are, with the exception of Stanley, nearly all in the Central Division, chiefly in the counties of Adelaide and Light. The soil, and climate are very suitable for the production of nearly every kind of wine ; the Adelaide plains yield a wine very similar to . those of the south of Spain, and the hilly districts produce clarets and other light- wines of very considerable quality. The. methods and apparatus employedin the early days of wine-making in the colony were of a very .primitive character, and "the South Australian vigneron has had to pass through a long and trying course of evolution before he reached the position which at this moment marks him as among the most enlightened wine-makers of the day. The wineries are models of cleanliness, and the fermenting houses - are of the most modem type. Spontaneous fermentation is no longer entirely* relied upon, but artificial cultures of the fermenting organism are introduced into the must with most satisfactory results. South Australians may pride MANUFACTURE OF BRANDY The Grape-Vine 253 themselves with having originated and perfected schemes for treating the grapes, which are now attracting the attention of wine-growers in all parts of the world. The progress of wine-growing in Victoria has been slow but sure, and in spite of many vicissitudes the production of wine promises at the present day to become one of the greatest industries of the colony. In 1860 the area under vines was about 2,000 acres, and some of the vines had already made their way abroad and obtained favourable recognition. But about this time a great rush for establishing vineyards took place, and in four years over 2,000 acres more were planted by people, the majority of whom had little or no experience of viticulture. The result was inevitable. The wines, made by the most unscientific methods, rapidly came into bad repute, and the trade almost completely died out. Not completely, however, for a few persevering men in the neighbourhood of Melbourne and other large towns, by careful and diligent work, were gradually improving their vintages, and in 1881 created the greatest sensation by winning at the Melbourne International Exhibition the grand prix offered by the late German Emperor " to an exhibitor in one of .the Australian colonies as an acknowledgment of the efforts in promoting art and industry as shown by the high quality of the goods manu- factured by such exhibitor." From that day colonial wine was no longer thrown under general condemnation ; it was seen that with careful scientific methods of cultivation and manufacture Victoria could produce wines which were not to be ignored, with the result that the colonists once more turned their attention to viti- culture. The most striking testimony to the excellence of Victorian wines has been afforded by some of the most famous growers of Europe— whose names are household words to the connoisseur — who have been forced to admit, generously enough, that many of the Australian wines are to be placed among the best that can be produced. The manufacture of cham- pagne has engaged the atten- tion of three or four growers in Victoria and New South Wales, and much experience has been gained as to the requirements of the industry under local conditions. Per- haps the best champagne has been produced by the Great Western Vineyard, about 139 miles from Melbourne, where the owner has been assisted in overcoming the great diffi- culty of regulating the tem- perature by the possession of huge caverns which have been hewn out of decayed granite rock twenty-five feet A COOPER S WORKSHOP 254 The World's Commercial Products below the surface. Hence the temperature remains at about 58° F., and shows very little variation throughout the year. With many of the difficulties inevitable to a new industry overcome, champagne-making at the present day promises to become an important branch of the Victorian wine industry. In New South Wales the grape-vine flourishes all along the coast district, especially in the country round Newcastle, and the wines of the Albury district, near the Victorian border, have a high reputation throughout Australia. The wine-growing industry of the State is still in its infancy, though with a growing local demand, and with the opening up of a market in England, where the wines of New South Wales, in common with those of Victoria and South Australia, enjoy a considerable popularity, the future -of grape- culture in the colony seems to be fairly assured. The vine was planted in the early days of colonisation in New South Wales, but it was not until 1828 that viticulture and wine-making became a definite industry of the country. About that time large numbers of stocks were imported from the finest wine-growing districts of Europe and planted in the Hunter River district, and a few years afterwards the Murray River valley received attention. The grapes flourished, but the wines manufactured from them were anything but satisfactory, the reason, as usual, being that the colonists but imper- fectly understood the vigneron's art. At the present time, however, neither pains nor money are spared to introduce skilled labour and to adopt up-to-date methods, and the results of such intelligent treatment are apparent in the status which the wines of New South Wales hold in the estimation of experts. VEGETABLES Among the commercial products of the world vegetables are a most important item, and their value as foodstuffs needs no emphasizing. The inhabitants of the world could subsist without animal-flesh, could scarcely subsist entirely on cereals, but they most certainly could not subsist without vegetables. Practically every nation, savage and civilized alike, cultivates a few plants for use as vegetables. The- vegetables we know and prize most are one and all the result of long cultivation, the origin of most being lost in antiquity. The world has been ransacked, and for the vege- tables cultivated in the United Kingdom nearly every country under the . sun has been laid under contribution. Large as are the supplies produced in the United King- dom, they are insufficient for the requirements of the people, and great quantities of raw vegetables are annually im- ported. In 1905 our imports of these commodities amounted in value to £13,872,842. In 1903 these imports totalled £15,319,994. The average for the last ten years amounts to over £12,300,000 per annum.

POTATOES The Potato {Solatium tuberosum) is the most import- ant of all vegetables from the point of view of the inhabit- ants of the British Isles. Its native country and the date of its introduction into Britain have been subjects of much discussion, but there can be no doubt of its being in- digenous to various parts of South America — plants hav- ing been found in a wild state on the Peruvian coast, as well as on the sterile tracts of Central Chili. The Spani- ards are believed to have first brought the potato to Europe from Quito in the early part of the sixteenth century. It afterwards found its way into Italy, and from thence it was carried to Mons in Belgium by one of the attendants of the Pope's legate. In 1598 it was sent from Mons to the celebrated botanist, Clusius, at Vienna, who states that in a short time it spread rapidly throughout Germany. The first potatoes that reached this country were brought from Virginia by the colonists sent out by Sir Walter Raleigh in 1584, and who returned in 1586. They were planted on Sir Walter's estate near Cork, and were used for food in Ireland long before they were even known, much less cultivated, in England. In the time of James I they were so rare as to cost 2s. per pound, and are mentioned in 1619 among the articles pro- vided for the Royal household. In 1633, when their valuable properties had become more generally known, the Royal Society took measures to encourage their cultivation with the view of preventing famine. However, it was not until nearly a century after the above date that they were grown to any great extent in England. In 1725 they were introduced into Scotland and cultivated with much success, first in gardens and afterwards (about 1760) in open fields. In a wild state the tubers of the potato are very small, seldom exceeding the size of a walnut. Under cultivation the plant has vastly improved and varieties innumerable have been raised. These varieties differ considerably not only in size, form and colour, but in the length of time taken to mature, and in being either waxy or dry and floury. It has been found that when a particular variety has been grown in the same soil for any length of time it degenerates and requires to be renewed either by seed, but more frequently by resorting to " sets " of sorts which have been grown in different soils and locality. In this way varieties are continually changing, and nearly every town or district has its particular favourite. Whilst the potato can be cultivated in almost any kind of soil and under widely different conditions, and after planting with a minimum amount of attention, it nevertheless responds to generous culture. A rich, light, warm soil suits it best, heavy cold soils being least desirable. The " sets " may be planted any time from February to the end of May, but March and early April are the best times. They should be planted in trenches four to six inches deep — allowing six inches between each set with the early kinds, to twenty inches with the late kinds. The trenches should be eighteen inches apart for the small-growing early kinds, and thirty-six to forty inches for the strong-growing late kinds. The potato being a sub-tropical 256 The World's Commercial Products plant will not withstand frost, and the early kinds should be afforded some protection if late frost occurs after the shoots are above the soil. The ground should be kept free of weeds, and when the shoots are about six inches high soil should be drawn up around them. The potato tuber is really a thickened underground stem borne at the ends of runners which originate in the axils of the lower stem leaves. By earthing up the stems the production of these is promoted and a heavier crop results. In 1845 a devastating disease made its appearance amongst potatoes in this country and threatened the entire destruction of the crop. This disease proved to be due to a Fungus {Phytophthora infestans), which first attacks the leaves, causing discoloration, and thence rapidly spreads down the stems to the tubers. Whilst no actual cure is at present known, spraying the crops at intervals with a solution of copper sulphate and lime (Bordeaux mixture) will check the disease if not actually destroy- ing it. Some varieties of potatoes are capable of resisting disease to a very considerable extent until they become degenerate. A disease-proof potato is a desideratum which plant breeders are endeavouring to fill. At present there is no such a thing absolutely, any more than there is a disease-proof wheat, dog, horse, or man. By a continual change of stock, care to plant only the best varieties, and judicious spraying, the disease can be kept in check if not in abeyance. The cultivation of the potato is now carried on in practically every part of the world — from Iceland to New Zealand, in Africa and distant China. In this latter country it was introduced by Roman Catholic missionaries some thirty years ago, and though despised by the rice- eating Chinese of the south, the potato has become a staple food of the peasants in the more mountainous parts of the Empire. In Great Britain and Ireland the potato is one of the most important crops. In 1905 no fewer than 1,225,228 acres were planted with potatoes. Lincolnshire, Yorkshire and Lancashire are the chief potato growing counties in England, followed by Cambridgeshire and Cheshire. Fifeshire, Forfarshire, and Perthshire are the principal Scotch counties. In 1905 the total yield for Great Britain and Ireland was 7,185,745 tons — the average yield per acre for the last ten years being 4'84 tons. In the same year Great Britain imported 3,664,290 cwt. of potatoes valued at £1,404,607. ^^F^-^WWflKzW^P* By permission of Messrs. Sutton & Sons, Reading BORECOLE OR KALE Copyright S. & S. *r Vegetables 257 Of the total imports 2,525,741 cwt. were from foreign countries, and 1,138,549 cwt. from British possessions. Nearly the whole of our imports consist of early new potatoes. SWEET POTATOES AND YAMS In tropical countries sweet potatoes and yams take the place of the ordinary potato. Yams, the tubers of various species of Dioscorea, are cultivated in nearly all tropical countries as important esculents. The Black Bryony of our hedgerows is a close relative of the yams, and has a large underground tuber which, how- ever, is of no use as a food. Yam tubers abound in farinaceous matter and often reach a large size, weighing as much as from thirty to sixty lbs. Sweet potatoes are the thick- ened roots of Ipomoea Batatas, a climbing plant belonging to the Bindweed or Convolvulus family. This plant is extensively culti- vated in most tropical countries, although not known in a wild state. The root contains much starch and saccharine matter. OTHER EDIBLE TUBERS ■"> .ftPE1 __ By permission of Messrs. Sutton & Sons, Reading CELERY Arracacha (Arr acacia escu- lenta), a plant allied to the parsnip and carrot, is extensively cultivated in the Andes, and has become naturalised in Jamaica. Under the name of " Crosnes " the tubers of Stachys tuberifera were introduced into this country by way of France from Northern China in 1887. Jerusalem Artichokes, the tubers of a sunflower (Helianthus iuberosus), originally intro- duced in the early part of the seventeenth century from the Northern United States of America, are widely cultivated as an article of food. PULSES These are all members of the Pea family, and are among the most important of foodstuffs ; they are cultivated and used in large quantities in all parts of the world. In countries like India and China, where, relatively speaking, very little meat is eaten by the natives, pulses are an absolute necessity cf life, constituting the chief nitrogenous foods. Before the spread of 258 The World's Commercial Products By permission of the Canadian Government EXPERIMENTAL PLANTATION OF POTATOES the potato, pulse (chiefly peas) formed a great part of the food of the working classes of the United Kingdom, and more especially in England. So important was this crop considered that in the letting or taking of a farm the acreage of Siddavv land (the term by which land that would grow good boiling peas was known in Gloucester, Hereford, and Worcester) was always taken into consideration. In 1905 no fewer than 428,497 acres of agricultural land in the United Kingdom were occupied with peas and beans, the total yield for 1905 being 12,707,747 bushels. In addition to this we imported in 1905, 3,240,926 cwt. of peas and beans, our average annual imports of these commodities for the last ten years being 4,374,220 cwt. PEAS The Common Pea (Pisum sativum) has been cultivated from very remote times. The pea plant is covered with a delicate glaucous bloom, and its white or pale violet flowers are familiar to all. The pods are pendulous, smooth, deep green, and variable in size and may contain any number up to thirteen (rarely more) peas. The peas when ripe are'also variable, some being white and round, others blue and wrinkled, and a few large, irregular, and dull green. Besides the varieties of peas whose seeds are edible, there is a section denominated u sugar peas,"' the members of which are destitute of the inner film peculiar to the pods of other kinds. They . are consequently more fleshy and crisp, and admit of being cut and dressed in exactly the same manner as French beans. This species is more popular in France than in this country. Vegetables 259 Field Peas. The original Grey Pea is supposed to be wild in Greece and the Levant, and is probably the original parent both of the few sorts of peas grown by the farmer and the countless numbers of still increasing kinds of the garden. In 1905, 172,931 acres in the United Kingdom were under peas, the total yield being 4,446,050 bushels. Of the total acreage, England's share was 171,110 acres. The average yield in the United Kingdom for the past ten years was 26' 24 bushels per acre. Our total imports of peas for 1905 was 2,015,876 cwt. Of these 1,056,360 cwt. came from British possessions. F BEANS Broad of Horse Beans rank with peas as the most important pulse crop cultivated in or imported into this country. The common bean is a hardy annual, generally believed to be a native of the shores of the Caspian Sea, as well as of Egypt and other parts of the Orient. The acreage under beans in the United Kingdom in 1905 was 255,566 acres. The total yield in 1905 in the United Kingdom was 8,261,697 bushels ; the average yield per acre for the last ten years being 27' 68 bushels per acre. The principal counties are Suffolk, Lincoln, Essex, and Cambridge. Beans are an important import into this country. In 1905 it amounted to 1,225,050 cwt. Of these 200,440 cwt. came from British- possessions. TROPICAL AND SUB-TROPICAL PULSES Whilst peas and beans are practically the only important pulse crops grown in this country, in tropical and sub-tropical countries their name is legion, and several demand more than mere passing notice in these pages. •jfc' NOVA SCOTIA. A FIELD OF ROOTS 260 The World's Commercial Products By permission of Messrs. Sutton & Sons, Reading MUSHROOMS Gram or Chick Pea (Cicer arietinum), an annual herb, cultivated from an early period- in warm countries, especi- ally in India, where it is used in cakes, curries, etc. Gram was known to the ancient Egyp- tians, Hebrews, and Greeks. The Persian weight, Nukhud, T±± oz. Avoird., is that of a seed of Cicer arieti- num. Gram is exported in considerable and increasing quantities from India ; the aver- age for the last five years being 422,436 cwt. In 1904-05 India Of this no less than £98,954 worth went exported 777,297 cwt. of gram valued at £178,993. to France. Lentils (Ervum Lens), a slender plant supposed to be native of Western Asia, Greece, and Italy. The Lentil was introduced into Egypt as a cultivated plant at an early date, and from this centre spread east and west. Large quantities of lentils are introduced into this country and used for soups, etc. The Soya Bean (Glycine hispida), a dwarf, bushy, almost erect plant, with every part covered with fine brownish hairs. The Soya Bean is widely cultivated in India, and more especially in China and Japan, where it is probably native. In the Far East " Soya " constitutes the most important pulse. Pigeon Pea or Dhol of commerce (Cajanus indicus) is an erect sub-shrubby plant, often about six feet in height, widely cultivated in the- tropics and sub-tropics of both hemispheres. The pea-like seeds are of two kinds — yellow and veined with purple. Considerable quantities are imported into Britain for use as cattle foods. Cow Pea (Vigna Catiang). This is a very curious plant, with long, almost cylindrical, pods one to two feet long. These pods are often gathered when green, cut into lengths, cooked and eaten like o'rdinary " kidney beans." The seeds are also largely used as food in the tropics. Lablab (Dolichos Labial), a tall climber, native of India, very similar to the common "kidney bean," but with the flowers dark purple and clustered at the ends of long stalks. Green Gram or Mung (Phaseolus Mungo), a native of India; where it has been cultivated for some 3,000 years. It is grown all over the Indian peninsula in immense quantities. The green. pods are eaten as a vegetable ; the ripe pulse is used boiled whole or split like Dhol. Parched and ground into flour it is used in a variety of ways. Green Gram is valued as a horse and cattle food, being considered fattening. The stems are crushed and used as fodder. Phaseolus Mungo, var. radiatus, is the most esteemed of all pulses in India, and fetches the highest price in the market. A native of India, it has been cultivated from time immemorial.. It differs from the type (P. Mungo) in its longer trailing habit, greater hairiness, and in the seeds being fewer, larger, longer, and usually of a dark-brown colour. Scarlet Runner (Phaseolus inultiflorus) , a native of South America, and said to have been Vegetables 261 introduced into Britain in 1633. Though usually considered to ,be a half-hardy annual and treated as such in gardens, it is really a tender perennial, having tuberous roots. Common Kidney or French Bean (P-haseoltis vulgaris), is of uncertain "origin, probably Asiatic, and is very generally cultivated in Europe and other temperate climes. As the result of long cultivation many varieties have originated, some dwarf in habit, others tall ; in some it is the seeds that are valued, in others the pods. In this country it is the young green pods which are most valued as a vegetable. THE CABBAGE FAMILY This family comprises some of the most ancient of culinary vegetables ; they are rich in sulphur, and possess antiscorbutic properties. The cabbage is found in a wild state in various parts of Europe and in southern England, always on maritime cliffs. It. is a biennial, with fleshy lobed leaves covered with a glaucous bloom ; altogether so different in form and appearance from the cabbage of our gardens that few would believe it could possibly have been the parent of so varied a progeny as are comprised in the Savoy, Brussels Sprouts, Cauliflower, Broccoli, and other numerous varieties. The Common or Cultivated Cabbage is well known, and from a very early period has been a favourite culinary vegetable in almost daily use throughout the civilised world. The Savoy Cabbage differs but little from other hearting cabbages. It is chiefly distinguished by its leaves being wrinkled in such a manner as to have a netted appearance. Brussels Sprouts, or Bud-bearing Cabbage (B. oleracea bullata minor), originated in Belgium, and has been cultivated around Brussels from time immemorial, although it is only within the last fifty years that it has become generally known in this country. Borecole (B. oleracea acephala) has every appearance of being one of the early removes from the original species. It is distinguished by its leaves being ^beautifully cut and curled, of a green or purple colour, or variegated with red, green, and yellow, never closing so as to form a heart, nor producing edible flower heads like a Cauliflower. Couve Tronchuda or Portugal Cabbage (B. oleracea costata) is a variety peculiar to Trauxuda, in Por- tugal, from whence it was introduced in 1821 to Britain. This is a singular cabbage with much thickened midribs which, when thoroughly boiled, make an excellent vegetable for serving up after the manner of Seakale. The Cauliflower {B. oleracea botrytis cauliflora) is of great antiquity, but its origin is unknown, although it is usually ascribed to Italy. It was introduced tO Britain during the Sixteenth Century. By permission of Messrs. Sutton & Sons, Reading In the cauliflower it is not the leaves chili and capsicum 262 The World's Commercial Products HOEING PUMPKINS but the flower-buds and fleshy flower-stalks, which form a close, firm head, four to eight inches across, that are valued. Whiteness and compactness and not mere size are the qualities esteemed. Broccoli {B. oleracea botrytis aspara- goides) is similar in form and appearance to the cauliflower, from which it is supposed to have originated. Several varieties of Broccoli are cultivated which vary in degree of hardiness and length of time taken to mature. Whilst the above are the varieties of cabbage best known to us, there are many other varieties cultivated in different parts of the world. One of the most interesting is the Chinese Cabbage. The Turnip (Brassica Rapa depressa) is a hardy biennial, and, in its wild state, is found in cornfields in various parts of England. The change it has undergone by cultivation is no less remarkable than that of the cabbage, but in this instance it is the root . which has been transformed from a comparatively hard woody substance into a fleshy and nutritious vegetable. Many varieties of turnip are known, some with round, others with long roots. The smaller kinds are valued in gardens as a vegetable, and the larger as field crops for cattle. The. Swede is a yellow and very firm-fleshed kind of turnip, introduced into Britain from Sweden. It is the Brassica campestris rutabaga of botanists, and is a valued agricultural crop in this country. Mangel Wurzel (root of scarcity) is the white form of Beta maritima, a plant found wild on the rocks and the seashores in Europe, Western Asia, and Northern Africa. In Britain it is not uncommon on the coasts south of Fife and Argyle. Sea Beet is a perennial, and has undergone remarkable changes under cultivation. The Red Beet is one form which is valued as a vegetable and salad in this country, but much more so in France and Germany. A .variety of Red Beet is the source of Beetroot sugar. The Tomato is an annual plant, native of the warmer parts of America, but long ago introduced into most other warm or temperate countries. The fruits of the tomato are red or yellow, and vary very much in size and shape, some being not larger than good-sized red currants. The Brinjal or Aubergine {Solatium Melongena) is closely allied to the tomato. . The Onion {Allium Cepa) is a bulbous plant allied to the lilies, and has been known and cultivated as an article of food from the earliest period. Many other important vegetables are allied to the onion, viz. : Leek, Shallot, Welsh Onion, Chives, and Garlic. All of these are highly valued in this and other countries. The garlic in some countries, especially China and the Far East, is the most highly esteemed of all. The. Cucumber {Cucumis sativus), is native of Asia and Egypt, where it has been cultivated for more than 3,000 years. It was known in England in the time of Edward III (1327), but its culture was neglected until the time of Henry VIII. Since then it has gradually increased in public favour until the present time. Vegetables 263 The Vegetable Marrow (Cucurbita ovifera) is closely allied to the cucumber, and is supposed to have been originally brought from Persia. Like the cucumber it is a tender annual, but succeeds out of doors in summer in this country. Many other members of the cucumber family are cultivated as esculents, notably in the warmer parts of the world. Of these the chief are Pumpkins, Melon Pumpkin, Water Melon, Chocho, Bottle Gourd, Squash. Asparagus (A. officinalis), a native of maritime parts of south-west England, is abundant in parts of Russia and Poland. It is also common in Greece and was esteemed as a vegetable by the Greeks and Romans by whom it was cultivated about 200 B.C. In this country asparagus is reckoned among the oldest and most delicate of our culinary vegetables. Forced asparagus was supplied to the London market as long ago as 1670. Capsicums or Chillies (Capsicum annuum and C. frutescens) are widely cultivated in .the warmer parts of both hemispheres. The fruits vary considerably in shape and size, and when green are cooked and eaten as a vegetable. Carrot (Daucus Carota), a biennial, native of Britain, is usually found in its wild state m light, sandy soil. It was introduced into England during the reign of Queen Elizabeth, and first cultivated in the neighbourhood of Sandwich, Kent. Parsnips, the roots of Peucedanum sativum, a biennial,, is a native of marshy places in Britain and elsewhere. The parsnip is closeiy allied to the carrot, and has been cultivated as an esculent from a very early period. Celery. Allied to the carrot and parsnip is the widely different-looking vegetable, celery (Apium graveolens). In a wild state the celery is found in the marshy places by the sea in England and Ireland. The blanched stalks are eaten as a vegetable. FRUITS Our annual import of raw fruits and nuts is an increasing one, and the average for the last ten years is estimated at £8,267,346 value annually. Canada, Australasia, West and East Indies, and latterly Cape Colony grow quantities of fruit for export to the United King- dom. But the continent of Europe, the near Orient, and the United States of America supply the bulk of our imports. Since the advent of cold storage the importation of fresh fruits from distant parts of the world has become simplified.

GROWING PINEAPPLES for fruit traffic, and, though there is still plenty of room for improvement in these matters, those inte- rested are keenly alive, and increased facilities may be reasonably expected. ORCHARD FRUITS The Apple (Pyrus Malus) is native to most of the countries of Europe, and is also found in the region of the Caucasus. In its wild state it is known (in Britain) as the crab, and from this the vast number of cultivated varie- ties have originated. The cultivation of the apple extends to the most northern extremity of Britain, and in Scandinavia as far north as lat. 65°. Whilst the apple-tree is amongst the hardiest of our fruit-trees, its blossoms are very susceptible to frost, and late May frosts often make sad havoc of the apple crop in this country. Although the apple exists in high latitudes, its fruit there is small — not" from excessive cold in winter, but for want of sufficient heat in summer. In Nova Scotia, where the winters are long and intensely cold and the summer short but very hot, the '-'apples are large and of splendid colour. In tropical climates the apple does not succeed, but in the temperate regions of both hemispheres it is very extensively cultivated. In the northern and middle regions of the United States of America and in parts of Canada, as in British Columbia, the produce is very fine. Parts of Australasia, notably Tasmania, produce very fine apples, and their culture is now successfully carried on in Cape Colony. Although apples are grown in most parts 'of Great Britain, the bulk are produced in the counties of Kent, Hereford, Devon, Somerset, Worcester, and Gloucester. The apple is the principal orchard crop in Great Britain, but the yield is quite insufficient for our needs, and huge quantities are annually imported. In 1905 we imported 3,494,660 cwt. of apples, valued at £2,065,193. Of these 2,005,428 cwt. were from foreign countries, principally the United States, and 1,489,232 cwt. from British possessions, particularly Canada. The Pear is less hardy than the apple, and requires more sun to perfect its fruits. In this country the best pears are obtained from trees grown against walls and sheltered from the cold winds. Most of the best varieties originated in France and Belgium, especially in gardens attached to religious establishments, and were introduced into England and other countries after the Battle of Waterloo. The pear is now almost as widely cultivated as the apple, and shares the same regions of the world. In California fruit-canning is a big industry, and everyone- is familiar with Californian tinned pears. The variety used, the so-called Bartlett Pear, is none other than William's " Bon Chrieten," one of the best early pears extant. The imports of pears into the United Kingdom in 1905 amounted to 417,919 cwt., valued 265 •; . 266 The World's Commercial Products at £407,817. Of these 401,237 cwt. were from foreign countries, chiefly France and the United States. The Medlar (Mespilus germanica), Loquat (Eriobotrya japonica), and Quince (Cydonia spp.), are all closely allied to the apple and pear. The fruit of the medlar is edible when well bletted, but is not so popular in Europe as formerly. The Loquat yields a small roundish or pear-shaped fruit, orange-yellow in colour, and pleasantly acid. It is a native of China and Japan, and commonly eaten there. The common quince (Cydonia vulgaris) is native to Southern Europe and Algeria, where it has been cultivated from time immemorial for its fruits, which were much revered by the ancients. Their chief use is for making jelly, which is highly esteemed,- especially in Canada and the United States of America. The name mar- malade is said to be derived from " Marmelo," the Portuguese name for quince. The plants are much used in England and the Continent as stocks for pear trees, especially those intended to be kept dwarf. STONE FRUITS The Plum {Primus domestica) is a native of the Caucasus and Asia Minor, naturalised in Greece and in most of the temperate regions of Europe. Cultivated varieties, according to Pliny, were brought from Syria into Greece and thence into Italy about 232 B.C. Many of the best varie- ties of plums cultivated in Britain were introduced from France and Italy cen- turies ago. The Orleans Plum, for instance, is sup- posed to have been brought over when the English held possession of that French city during the reign of Henry V. Prunes are dried plums prepared in France, Ger- many, and other parts of the continent. The neigh- bourhood of Tours, in France, is celebrated for its prunes. The prunes which come from the south of France are prepared from a variety called " Perdrigon." German prunes are prepared from an oblong purple variety called " Zwetsche." The Damson, a small oval, purple plum, is very largely cultivated in this country for making into preserves. The damson is highly productive and more hardy than the ordinary plum. Plums are widely grown trinidad. custard apple in Britain, especially in Fruits 267 Photo by A*. P. Edwards, I.iUl champion MYSORE. A GIGANTIC MANGO TREE certain districts like Kent and the Vale of Evesham, but owing to late spring frosts which frequently prevail the crop is very uncertain. The bulk of our supply comes from France and Germany. The Apricot (Prunus Armeniaca) is supposed to be native to Armenia, but is now naturalised in India, China, Egypt, and other parts of the world. The apricot was introduced into cultivation in Italy about the beginning of the Christian era ; from Italy it is said to have been introduced into England by Woolf, gardener to Henry VIII, in 1534. The apricot thrives in California and other parts of the United States of America. In Australia it is successfully grown, and quite recently most excellent apricots have reached this country from Cape Colony. There are many varieties : one, the Musch-Musch, with sweet kernels, is grown in the oases of Upper . Egypt, where the fruit is dried and forms an article of commerce. Dried apricots are also prepared in northern India, and find their way across Tibet to Western China, and are esteemed by Tibetans and Chinese alike. The apricot is somewhat extensively grown in France, and from there we draw the bulk of our supply. The Peach (Prunus persica) is the most esteemed and luscious of fruits of the plum tribe. It is, in all probability, a native of China, where it has been cultivated from a very remote period. From China peach-stones were probably carried by the old trade route to Bokhara and Persia. From Persia the peach was introduced into Asia Minor and Europe somewhere about 300 B.C. There are three distinct forms of peach — clingstones, freestones, and nectarines — and numerous varieties of each form. English-grown peaches are preferred in this country to those of any other land, and in every garden of note greenhouses and walls are devoted expressly to the culture of this delicious dessert fruit. The imports of peaches into this country, like those of 268 The World's Commercial Products apricots, are small, and come chiefly from France. A few come from the United States, Canada, and, latterly, from Cape Colony. Cherries. The numerous varieties of cultivated cherries have in all probability originated from Prunus Avium and Prunus Cerasus. Those belonging to P. Avium, of which the Bigarreau and the Black Heart may be instanced as typical of the better kinds, have generally larger, thinner, and more pendulous leaves, and fruits more yellowish-green in colour than those of P. Cerasus. From this latter species are derived such well-known varieties as May Duke, Kentish, and Morello, with red, dark red, or nearly black juicy fruits. Both species are natives of Europe and parts of Asia, and are very widely cultivated. The cherry is one of the commonest fruit trees in Britain, and in some parts, notably Kent, great quantities are grown. It is said that the present race of cherries cultivated in Britain was introduced from Holland and Belgium during the reign of Henry VIII. Large quantities of cherries are annually imported into this country from France ; lesser quantities from Germany, Netherlands, and Belgium. Occasionally small consignments arrive from Canada. SMALL FRUITS Red Currants (Ribes rubrum) and Black Currants (R. nigrum) must not be confused with the dried currants of the shops, which are the fruits of a kind of grape. Both red and black currants are natives of northern and central Europe, and extend across northern Asia to the shores of the Pacific.

A TYPICAL PINERY Fruits 269 in this country we import currants in considerable quantities from the continent of Europe — principally France, Netherlands, and Belgium. In 1905 our imports of currants amounted to 82,286 cwt. The Gooseberry (Ribes Grossularia) is found wild in this country and in many other parts of Europe ; it extends eastwards to the borders of China and in Eastern Tibet is commonly used as a hedge-plant. The plant is very hardy, and in Norway its successful culture extends as far north as lat. 66°. Cool climates suit it best, and in the north of England and in Scotland it thrives better than further south. The gooseberry has many local names even in this country. In Scotland it is called " Grozet," in France " Groseille " (the French use the fruit for making a sauce for mackerel), to the Germans it is the " Krausel beere " or " Stachel-beere," to the Dutch " Kruisbes " or " Kruisbezie," to the Danes and Swedes the " Krusbaar." The Raspberry (Rubus Idaeus) is closely allied to the blackberry of our hedgerows. A native of Britain and most of the countries of Europe, the raspberry grows wild as far north as lat. 70° and southward in Asia Minor to lat. 39° 40'. This fruit was well known to the ancients, and has been cultivated from time immemorial. Many species of Rubus have been taken in hand by horticul- turists and hybridists, and some valuable fruiting kinds raised. One, called the Loganberry, raised in America, has gained a wide reputa- tion for its line fruits. The Japanese Wine-berry (R. phcenicolasius) is cultivated in Europe and America for its ornamental appearance as well as for its edible fruits. The Mulberry (Moms nigra) is a small tree belonging to the stinging- nettle family. The fruits are black, luscious, and vinous, and were formerly much more esteemed in this country. The Strawberry (Fragaria virginiana) is one of the most familiar and prized of all English- grown fruits. A native of Virginia, it was introduced into this country in 1629, and has been cultivated in increasing quantities ever since. Formerly, the immediate neighbourhood of London — Mortlake, Twickenham, and Isleworth — was a great strawberry-growing district, but, owing to the demands of the builder, the cult has been removed farther afield. Parts of Hampshire, Cambridge, Surrey, and Kent are noted for their strawberries. The strawberry crop is one of the most certain ' of all crops in .this country, provided the plants are properly looked after, and not allowed to surfer from drought. They " force " well, and the early English strawberries of the shops are all grown in pots or frames under glass. The strawberries consumed in this country are chiefly hbm'e-grown ; France and the Netherlands are the only countries from which we import any appreciable quantity. THE GUAVA FRUIT 270 The World's Commercial Products EXOTIC FRUITS The Common Orange, also known as the Sweet- or Chinese Orange (Citrus.- A urantium), is probably a native of China, where it is widely cultivated. This orange forms a low, very bushy, evergreen tree with very hard wood, and lives to a great age.. The fruits are borne in great profusion, and orchards of orange-trees loaded with ripe fruits present one of the most beautiful sights imaginable. In favoured spots in the south-west of England oranges succeed against warm walls protected in winter, but they are usually- grown in structures termed " orangeries." Owing to the indifferent results, the expense involved, and the ease and cheapness with which oranges can be imported from south Europe and elsewhere, their culture jn this country has been practically abandoned. From Stereograph Copyright, Underwood & Underwood, London & New York . A FRUIT RANCH AT LOS ANGELOS, CALIFORNIA Under favourable circumstances the productiveness of the orange is astonishing. In the island of St. Michael a single tree has been said to produce 20,000 oranges fit for exportation ! There are many varieties of this orange as the result of its wide cultivation ; some are of great value, others of but little merit. Among the more familiar and esteemed are the Blood Orange, Saint Michael's, and Sweet-skinned Oranges. The blood orange has a round fruit, rough red cr reddish-yellow outside, with a pulp irregularly mottled with crimson. The St. Michael's Orange has a rather small fruit, pale yellow and seedless, with a very thin rind and very sweet pulp. The sweet-skinned orange is the Forbidden Fruit (" Pomme d'Adam ") of the Paris shops, but not of London. The rind is smooth, deep' yellow, very thick, and sweet. The Seville or Bitter Orange (C. Aurantium, van Bigaradia) was introduced into Arabia, like the sweet orange, from India by the Arabs in the ninth century. From Arabia it was carried by way of Egypt and north Africa to Spain, probably by the Moors. It was in cultivation at Seville about the end of the twelfth century. The fruit of the Seville orange is round, dark-coloured, with an uneven, rugged, and very bitter rind. The fruit is largely used for making marmalade, and the rind for making candied orange peel. The ripe fruit is also made into a syrup, and is one of the principal ingredients of the liqueur Curafoa. 271 272 The World's Commercial Products ■ The Bergamot Orange' (C. Aurantium, var. Berganiia) produces small pyriform fruits, the pulp of which is acid and bitter ; the rind is thin, golden yellow, and filled with a sweet essence. Formerly, sweetmeats called bergamottes were made of it ; now it is only used for the expression of oil of bergamot. This variety is chiefly cultivated in the South of France, in Sicily, and near Reggio in South Calabria. The Mandarin or Maltese Orange (Citrus nobilis) is a native of China, but is now as widely cultivated as the sweet orange. In Malta and the Azores this orange is very successfully cultivated. The fruit ' is small, flattened, with a thin rind which separates spon- taneously from the pulp, so that when quite ripe the latter may be shaken about inside. The pulp is exceed- ingly rich and sweet ; unfor- tunately this variety does not keep so well as the ordinary orange. The Mandarin orange is largely grown in China, and certain districts, notably Swatow, are famed for this variety. Oranges form the largest item in the fruit imports of the United Kingdom. In 1905 our total imports were 5,068,526 cwt., valued at £1,949,496. The total imports of oranges from British posses- sions was only 104,901 cwt. ; of these no fewer than 103,257 cwt. were from the West Indies, which produce excellent fruit. The Citron (C. medico) has been found wild in the Khasia Hills and other parts of northern India. It is cul- tivated in China, Cochin China, and in all the warm, moist parts of India. It reached Europe by way of Persia. The Jews cultivated the citron at the time they were under subjection to the Romans, and used the fruit then, as now, in the Feast of Tabernacles. At the present day the citron is cultivated in Sicily, Corsica, Italy, Spain, Portugal, West Indies, and Brazil. The inner rind of the citron is thick and fleshy, and a pleasant preserve is prepared from it. Candied citron rind is well known. The Lemon {Citrus medica, var. Limonum) is possibly a native of India or China, but its original habitat is uncertain. It is cultivated in the above countries, and found its way to Europe from India about a century after the orange. There is a considerable import of lemons into the United Kingdom. In 1905 our total THE MANGO FRUIT Fruits 273 imports were 837,028 cwt., valued at £419,049. Of these, 834,884 cwt. were from foreign countries, chiefly from Italy. Of the total imports from British possessions (2,184 cwt.) West Indies contributed 2,088 cwt. The Lime (C. medica, var. acida) is native to the warm valleys of the outer Hima- laya ; it is cultivated in India, Burma, West Indies, etc. In the West Indies the cultivation of the lime is now conducted on a large scale for the sake of the juice, which is imported into this and other countries in large quantities. Green limes are also in con- siderable demand, especially in the United States of America. The ordinary lime is a very spiny tree, but a variety originated at Dominica in the West Indies is absolutely spineless. A seedless lime has been discovered in Trinidad. The Sweet Lime (C. medica, var. Limetta) is a native of Southern India, where it is also cultivated. Sweet limes are eaten fresh or preserved. The juice is not so much valued as that of the Sour Lime. The Shaddock (C. Decumana) is native of the Malay Archipelago, the Friendly Islands, and Fiji. The fruit is very large, weighing sometimes from ten to twenty pounds, roundish or oblong, with a smooth, pale-yellow skin, and white or reddish sub-acid pulp. The " Grape Fruit " of the West Indies is also a superior variety of this same species. Bananas. The banana has during the last few years advanced rapidly in popularity in Great Britain. The old-established kind is the China or Canary Banana, the fruit of Musa Cavendishii, originally discovered in China, but now cultivated in many parts of the world. The more recent introduction, the large banana, is usually known as the Jamaica banana, the supplies coming from there, from Costa Rica, and neighbouring places. This is the fruit of another species, M. sapientum, var. paradisiaca, also probably an Asiatic plant. The cultivated banana is seedless (indicative of the ages during which it has been grown), and propagation is effected by cuttings. The plants form below ground a huge rootstock, which gives off suckers or shoots. One of these cut off with a piece of the rootstock and set in the ground grows very rapidly, forming a plant of the habit shown in the illustration, with large, broad, deep-green leaves, at first entire but which soon split into innumerable strips when exposed to wind. 19— C.P.

AN ORANGE CLUSTER 274 The World's Commercial Products The China or Canary Banana plant, is usually about four or six feet in height. Large quan- tities of this variety are cultivated in Madeira and the Canary Islands, and most of the market supplies are derived from these sources.- The fruits have. to be cut before they are ripe, and the best time is when theyjiave lost their early angularity and have become round and full, but are still quite green.- They are carefully wrapped in cotton wool, paper, dry banana leaves, and packed in open sided crates. They can be carried on the decks of steamers or in a cool room to the receiving port ; ripening continues during the voyage so long as the fruit is not exposed to either too high or too low a temperature. The Jamaica banana is a much larger plant, often twelve feet or so in height. The fruit is larger also, and having a thicker skin it can be shipped without the expense of the costly packing in crates being necessary. Ships with specially fitted rooms are provided on the Direct West India Service, and in these the bunches are placed loose.. Bananas are now the chief export of Jamaica, the'annual trade being over £1,000,000, chiefly with the United States. Recently an effort was made to export bananas from Barbados to England. The Canary method of packing was' adopted, and the fruits arrived in England in good condition and realised high prices. Improved shipping facilities are the principal requisite to ensure a successful trade. A dull, purple-coloured banana is sometimes to be seen in the fruiterer's. This is the Claret Banana. It is not to every taste of such good flavour as the preceding, but is in certain demand owing to its'colour, which makes it an interesting addition to table dessert.

In this country a great many varie- ties of grape are cultivated, practically all under glass, and English hot-house grapes are considered the finest grapes in the world. Else- where in this work the vine is treated at length, and it is sufficient in this place to note its value as a fruit. Considerable quantities of grapes are imported into this country. In 1905 we imported 700,050 cwt. of grapes, valued at £761,632. Of these, 664,383 cwt. were from foreign countries, chiefly Spain,which sent 543,807 cwt. From British possessions came 35,667 cwt., Channel Isles 33,863 cwt., Cape Colony 1,645 cwt. Raisins are the- dried fruits of a peculiar variety of V. vinifera, cultivated in Greece. Sultanas are the dried fruits of a seedless variety of this same species, .- also largely cultivated in Greece. The Black Corinth or Zante grape, a variety of V. vinifera, supposed to have originated near Corinth, and- very widely cultivated in the Greek Archipelago, furnishes the dried currants of commerce. Dates are' the fruits of the date palm (Phcenix dactyli/era). This palm is a native of the dry, hot regions of Northern Africa ; it is also cultivated there in immense quantities, and more sparingly in Western Asia and Southern Europe. In the dry parts of Northern Africa it is the principal food of a large proportion of the inhabitants, and likewise of the various domestic animals — dogs, horses, and camels being alike partial to, it. The Fig (Ficus Carica) is a deciduous tree, growing fifteen to twenty-five feet high in favourable climates ; native probably of Asia Minor, but now very widely cultivated. The fig is hardy in the more favoured parts of the United Kingdom, and when grown agamst sunny walls or under glass fruits readily. Figs grown in this country are seedless, anjd&Jije usually eaten in a green state. Figs when fresh are pear or urn-shaped. Drying -is effected in a warfn climate by. expoj to the sun's rays.- In drying some of the grape sugar. exudes and forms a white powder, dried figs are packed in boxes under pressure, and constitute the figs of commerce. The figs imported into this country mostly come from the Mediterranean region, notably Turkey and Asia Minor. The Pineapple (Ananas sativus) is universally acknowledged to be one of the most TRINIDAD. THE CASHEW FRUIT 276 The World's Commercial Products delicious fruits in existence. A native of Brazil, it is now cultivated in the" tropics of both old and new worlds. Its cultivation is also successfully carried on in hot-houses in this country, and, strange as it may seem, English-grown pineapples surpass in size and flavour 'those grown in the tropics. Large quantities of pineapples are imported into this country chiefly from the' Bahamas and other West Indian islands. 'o.. Mango (Mangifera indica), a medium-sized tree with large egg-shaped-fruit, a native of India, and now cultivated throughout the tropics of the world. There are many varieties of Mango differing in size, shape, and flavour. The better kinds are esteemed among the finest of tropical fruits ; the inferior ones are practically inedible. The unripe fruits are much used in India in conserves and tarts, and in the making of chutney. Olives. Pickling olives are the unripe fruits of Olea europaea, deprived of a portion of their bitterness by soaking in water to which lime and wood ashes are sometimes added, and then bottled in salt and water flavoured with aromatics. The olive is a small- growing evergreen tree, native, in all probability, of parts of Southern Europe and Asia Minor and cultivated largely on the shores of the Mediterranean ; also in California, Aus- tralia, and other parts of the world. It is chiefly grown for its excellent oil. The tree is very slow growing and lives to a great age. The Pomegran- ate (Punica Grana- tum), native of Upper India, and possibly Northern Africa and Western Asia, is usually a large bush or small tree, fifteen to twenty-five feet high, with scarlet flowers and large globular fruits. Pomegranates are greatly valued in warm countries on account of their de- licious cooling and refreshing pulp. By permission of Messrs. Duperly & Son, Kingston, Jamaica JAMAICA.

The fruits of all are large, with white or yellowish pulp, very juicy, with pleasant acid taste. The quality of these fruits varies in different lands, some being more appreciated than others. (See illustrations on p. 70 and p. 266.) ) Avocado Pear (Persa gratissima) is a common tree in tropical America and the West Indies, where it attains the height of from twenty-five to thirty feet. The flesh surrounding the stone is yellow and green, soft, and buttery, with a delicious flavour. The fruits are usually eaten raw with pepper and salt, or lime juice. The Papaw (Carica Papaya) is native of South America, but is now cosmopolitan in the tropics. The tree is of rapid growth and will thrive in almost any soil. The flavour is similar to that of a melon and the fruit is most wholesome. The Guava (Psidium Guaiava) and the Purple Guava (P. cattleyanum) are well-known tropical fruits. Both are natives of the West Indies and tropical America. They are eaten raw and make very good jelly or preserve. Litchis, occasionally sold in shops in this country, are the dried fruits of Nephelium Litchi, a tree wild and cultivated in the warmer parts of China, and in Cochin China and Malaya. When fresh the fruits are very luscious. They are also canned and exported from Hongkong. Almonds. The Almond tree (Prunus Amygdalus) grows to the height of about twenty feet, and has leaves similar to the peach, but larger flowers. A native of Persia, Asia Minor, Syria, and Algeria, it is now widely spread in the warm temperate parts of the Old World. It is largely cultivated in the Mediterranean region, notably Spain, Italy, and Morocco, for the kernels of its seeds, which constitute the almonds of commerce. 278 The World's Commercial Products Sweet Chestnuts are the fruits of Cas- tanea sativa, a large tree closely allied to the oak, a native of Asia Minor and other parts of Asia, and now very widely cultivated. Trie nuts are highly nutritious. We obtain the bulk of our supplies from Spain, for although the Sweet Chestnut ripens its fruit in this country they are small and of little value. Coconuts, the fruits of the well-known coco-nut palm (Cocos nucifera) now widely spread in the maritime regions of the tropics. Elsewhere in this work the coco-nut is dealt with at length.

Brazil Nuts are the products oi*Bertholletia excelsa, a very large tree, native to the forests of South America. The nuts are principally exported from the port of Para in Brazil. Walnuts of commerce are the fruits of Juglans regia denuded of their pulp. The tree is a native of Persia, temperate Himalaya, and China, and has been cultivated in temperate Europe from great antiquity. Juglans cinerea yields the Butter Nut of North America. The Hickory Nuts (Carya alba and C. nigra) are closely allied to the walnut,' and largely eaten in North America. The Pea Nut {Carya glabra) and Pecan Nut (C olivceforniis) are also natives of North America. Ground Nuts, the fruits of Arachis hyftogoea, are largely eaten' as dessert in America, China, and elsewhere. Cashew Nuts are the fruits of Anacardium occidentale, native to tropical America and the West Indies. The actual nut is the small body borne at the apex of the swollen coloured fruit stalk (see illustration on p. 275). They are very delicious when roasted, but as yet are but little known in this country. papaw RUBBER Rubber,' india-rubber, or caoutchouc, is obtained from the milky juice or latex of various plants, mainly found in 'tropical' countries. There are in the' United Kingdom many latex yielding plants, such as the common wayside milkweeds or spurges, poppies, periwinkles, etc., but they are not commercial sources of rubber. The actual rubber is a mixture of chemical bodies known as hydrocarbons, resins, water, and various other substances, varying with the kind of rubber, i.e., which plant it is obtained from, the method of preparation, purity, and so on. Commercial rubbers are distinguished by names denoting often the country of origin, such as Para rubber, Ceara rubber, Lagos silk rubber, etc. We will now proceed to give a brief account of the plants, and the method of cultivation and preparation of each of the chief kinds of rubber : — 279 2SC The World's Commercial Products liv permission of Sfessrs. Maclaren, Shoe Lam RUBBER -TREES TWENTY YEARS OLD PARA RUBBER In tropical South America, in the basin of the Amazon and of the Orinoco, occur a number of trees of the genus Hevca, belonging to the Spurge Order (Euphorbiaceae), which yield rubber. The best known is Hevca brasiliensis, which is usually' looked upon as the source of Para rubber, so called from the town of this name near one of the mouths of the Amazon, whence much of the rubber from Brazil is exported. Comparatively little is known with certainty as to the trees contributing to the rubber shipped from Brazil, but this is not altogether to be wondered at when we recollect that the rubber region embraces an area about two-thirds that of Europe ; that the trees occur wild in dense forests and their produce is collected by natives and brought do,vn for sale. Several species of Hevea are recorded as rubber producers in different districts, and members of. other genera also contribute, but Hevca brasiliensis is, at any rate, one of the most important, and this is the tree which has been introduced with great success into other regions of the world, and is the source of the important and rapidly developing Para rubrjer industries of Ceylon and British Malaya, so that it is generally spoken of as the Pai^a Rubber Tree. ' Hcvea brasiliensis thrives in the hot, damp forests of the Amazon valley, in what are known as the " islands " in the delta of the river, and also in the higher lands lying back from the valley of the river/ The climate of this region is extraordinarily uniform, the annual mean temperature being about 80° F., and the daily range usually between 75° and 90°. The annual rairlfa'll is from, 80 to 120 inches. tto ^general" habit of the Para rubber tree will readily be seen from the various illustrations. It attains a height of over sixty feet and a girth of eight to ten feet. The leaves are charac- teristically three lobed, the flowers are individually small and inconspicuous, but are borne Rubber 281 in little sprays, and are succeeded by dry fruits each, containing three seeds about the size of large Kentish cob' nuts, and with the curious brown and black mottling so characteristic of seeds of many plants of tins family, e.g., the castor oil-bean. The seeds are very oily and soon lose their vitality, so that special precautions have to be taken to transport them successfully over long 'distances when required for propagation. Collection of Wild Rubber ■ In Brazil, the trees are tapped during the dry season, which varies in different districts. The rubber collectors or serin- guieros search the forests for suitable trees which should not be less than about two feet in girth. An incision is made in the bark with an axe or cutlass and a receptacle fastened imme- diately beneath. The latex be- gins to run at once and is caught. A number of cuts are made in each tree, a cup fastened under each, and allowed to re- main for a few hours. At the end of this time the flow of latex has ceased and the con- tents of all the little cups transferred to a larger vessel. The next step is to convert the still liquid latex into solid rubber. A fire is lighted and nuts of various species of palms placed on it. These produce a dense smoke containing acetic acid and creosote, which rapidly coagulates any latex exposed to it. A kind of paddle is dipped in the latex and held in the smoke. The rubber coagulates, forming a thin layer on the paddle. This is then dipped into the latex and again smoked. Another layer is deposited on the first, and the process is continued until a sufficiently large mass of solid rubber has been collected on the paddle. It is then removed and is ready for sale and export. Plantation of Para Rubber It will be convenient to pre- sent under this heading a resume Bv permission of Mcss-s.

The World's Commercial Products of the steps taken to establish the Para rubber tree as a cultivated plant in various, parts of the iworld, with special . reference to Ceylon, and British Malaya, in which the most important results have been attained. In 1896 Ceylon received from the Royal " Botanic Gardens, K-'ew, some 2,000 seedlings of this valuable plant. The seeds had been, collected in Brazil by Mr. H. A. Wickham,' forwarded to Kew, and despatched thence to Ceylon in Wardian casesV A Wardian case, it may be said, is essentially a small portable glass-roofed box, in which plants are placed with a supply of soil and moisture so that they can be sent long journeys without injury. This is of particular importance to the plant. The cost of the experi-' ment was borne' by "the Indian Government, but Ceylon was selected as having a more suitable climate, and tHe young seedlings were mostly planted out in a special garden at Heneratgoda, in the hot and moist region of the island. As early as 1897-8 young plants, raised from cuttings, were distributed to Madras, British Burma, and the Straits Settlements, and after the first flowering in 1881, ' when seedlings became available, the work of dis- tribution was continued, and Aus- tralia, Fiji, the West Indies, Sey- chelles, and the west "coast Of Africa are amongst' the widely ; separated places into which Para rubber plants have been introduced. The: use of Wardian cases is the most satisfactory manner of transport over long distances, the seeds germinating en route, but very successful results- have been attained -with carefully dried fresh seeds packed in tins in dry powdered charcoal and... coco-nut! fibre dust, or sawdust. It- was at first thought that, the plant would only grow on moist,, preferably periodically.' inundated ground, and near the sea level. This, however, has proved not to be the case, and good.' results have been, attained in Ceylon up to. an elevation of: 2,000 feet, and in some cases even higher. .The- other requirements are practically those indicated as existing in the Amazon valley, i.e.,. a rainfall of about 100 inches per annum, and a mean annual temperature of about 80° F. The plant grows very rapidly from seeds, the seedlings being raised in nurseries. The distance the plants are set apart depends on various causes, but if ten feet by fifteen feet is adopted the result will be 290 trees to the f acre. If eighteen feet by eighteen , By permission of Messrs.

In some cases it is advisa- ble to plant compara- tively closely, and tap the trees until they become crowded, and then by removing the worst give the others room for further development. During the first four years, catch crops such as ground nuts, cas- sava, bananas, cotton, etc., can be grown. Sometimes the rubber plants are set amongst matured coffee (see p. 187) or tea, with the idea of removing the coffee or tea altogether later on, i.e., gradually transforming a tea or coffee estate into a rubber estate. Tapping. Under good conditions Para rubber trees are ready for tapping when about five years old. The old method in Ceylon was to make V-shaped in- cisions in the tree, after the bark had been care- fully cleaned, and to catch the latex which ran out in pieces of -coco-nut shells placed on the ground, matters being so arranged that the latex from several Cuts formed one stream, so that about three shells caught all the produce of a medium- -sized tree. The latex was allowed to remain in the shells, where it rapidly coagulated and was later removed. Some of- the latex coagulated before it reached the cups, in narrow -strips which were peeled off the trunk and wound up into balls of "scrap rubber." *** 'As 'the result of careful experiments in" Ceylon' by Dr. J. C. Willis, the present Director •of the Ceylon Botanic Gardens, and Mr. Parkin, an improved method was devised. The latex from each V-shaped cut was collected ih a separate tin cup containing a little water, to keep the latex liquid for a while. The diluted latex was strained and poured into shallow dishes, a small •quantity of acetic acid, and creosote being usually added to assist the process of coagulation. By. permission of Messrs. -Mr.cl.:re;i, Shoe Lane vOLD TREES WHICH HAVE BEEN TAPPED BY THE SINGLE-INCISION ■ - Rubber 285- Here it coagulated, and as a result a cake or " biscuit " of rubber about i in. thick was obtained, which was thoroughly dried by rolling arid other means. (See illustration on p. 290.) These experiments resulted in putting on the marketthe now well-known " Para -biscuks," which have earned a high reputation for their purity. They entail, however, a large amount of hancj labour, and are accordingly being replaced at the present time by other and more expeditious methods. Before we refer to those it will be convenient to note that much experimental work has been and is being done in methods of tapping. The little cups, each under a separate cut, also- demand a lot of labour, and it is found advantageous to collect the latex in as few cups as possible, some going so far as to suggest catching the yield of more than one tree in a single receptacle by means of suitable guiding channels. The " herring-bone " method ismow largely adopted. It consists of a vertical cut several feet' long, with branch cuts leaving it at an angle of about 45° alternately on either side. The branch cuts point upwards; and. the latex from them runs into the central vertical cut at the lower end of which the cup is placed. In tne half herring-bone branch cuts are made only on one side of the vertical cut. Still more recent is the spiral mode of tapping. A series of cuts running spirally half-way round the tree is made from a height of six feet or so to the base. This method appears to be very successful. It has the advantage that as the wounds in the bark heal, the old places can be readily tapped again, and in the Para rubber the yield from over the same area increases rapidly at successive tappings, an interest- ing and important phenomenon spoken of generally as " wound-response." The yields from some of the spiral tappings in Ceylon have been very high, as much as 25 lb. of rubber from a single tree in a year, without the tree showing any ill effects. Such a yield is, no doubt, ex- ceptional, but for trees between five and ten years old, grown under By permission of Messrs.

Now there are many patterns of tapping knives and " prickers " on the market, designed to carry out different styles of tapping in the best possible manner, and with the least injury to the tree. Particulars of these will be found in the work on " Hevea brasiliensis or Para Rubber,"" by H. Wright, Controller of the Experiment Station, Ceylon, which affords a comprehensive summary of information relating to the rubber industry in that colony. Even the shavings obtained in the tapping operation need not be wasted, but their rubber contents can be extracted. Rubber 287 Sheet Rubber. This is prepared in the same way as biscuit rubber, but in rectangular instead of circular receptacles. There are certain difficulties in handling and -transporting these thin sheets, and recently a plan has been devised of pressing sheets or biscuits into blocks with satisfactory results. . • Crepe Rubber is another modern commercial form of plantation rubber;: The latex is coagulated " in bulk " instead of in separate small receptacles. A large irregular mass of rubber is obtained which is passed thro.ugh a > washings machine and obtained finally, in long thin ribands, perforated .with small holes, and roughly resembling crepe in texture. Worm Rubber is also coagulated in bulk, pressed -into thin sheets, which arexut up by large shears into irregular more or less- .worm-like pieces. Lace Rubber is very similar to crepe, rubber. All these last three forms can be made very •expeditiously by the aid of- machinery and have the great "advantage of drying much more rapidly than the solid, sheets or biscuits. Plantation Para rubber is in art active experimental stage, and producer and buyer are •co-operating to rind the most ; advantageous method of preparation.

The plant has been known to science longer'than any of the other rubber-yielding plants, and was first described- by, Cervantes at a meeting of the Royal Botanic Garden of Mexico in July, 1794, arid Copies; of his original published description, with *a figure of the foliage and flowers of the plant,- are still in existence, although now very rare. The rubber By permission of Messrs. Maclaren, Shoe Lane FICUS ELASTICA ; SHOWING ROOTS FEEDING ON DEAD WOOD 288 The World's Commercial Products passes commercially under a great variety of names, mainly denoting the country from which it has been obtained. The tree is also known under different local names ; the Spanish name is Hule or Ule ; the native Aztecs called it Olquaquitl ; other names which have been applied to the plant are Caucho and Tunu. Although we have referred to this rubber as being obtained from one species of plant, there is considerable doubt as to whether this is strictly accurate, and Koschny, who^ has devoted great attention to the tree in Costa Rica, distinguishes and gives separate names to four distinct kinds or varieties, three of which yield rubber whilst the latex of the other forms only a resinous, brittle mass of no value. It is convenient to include all these varieties under the general name of Castilloa elastica, bearing in mind that we may be dealing with several closely related plants, rather than with only one species. The Central American rubber tree is found in the forests in its native country, but it does not follow from this that it should be grown in forests or under the shade of other trees, when efforts are made to cultivate it. One reason for its only occurring in forests appears to be that its seeds are very thin-walled, and are rapidly killed if left exposed on open ground under the fierce heat of the tropical sun. When artificially sown, cared for, and shaded in its early stages, the plant has been found in other coun- tries to grow more quickly, and to give better results in the open than in the shade. Similar instances are not uncommon in the plant world It develops into a very large tree, sometimes more than 150 feet in height, with a rather smooth, light grey bark, and easily recognised in the young state amongst other trees by its peculiar branches bearing on either side a row of large leaves, generally about one to one and a half feet long (see Fig. on p. 282). These branches fall off later, and are succeeded by others of less characteristic form. The plant appears to thrive best in deep, loamy soil, near the banks of streams, and in valleys, but it does not like swampy or boggy land. Like most of the rubber trees, it cannot be grown with success in places where the temperature falls below about 60° F. at any season of the year. A continuously humid climate is not necessary, and so far as observations go the yield of rubber is greater from trees growing in regions where wet and dry seasons alternate. In the past the rubber was principally collected from wild trees, and as has happened in other parts of the world with other kinds of rubber-yielding plants, this led to the destruction, and in places almost complete extermination, of the plant. When the plants are wild the By permission of Messrs. Maclaren, Shoe Lane NEAR VIEW OF HEVEA BRASILIENSIS From stereograph copyright by Underwood & Underwood, London & New York Coloured by Miss St CURIOUS ROOTS AND TRUNK OF THE INDIA RUBBER TREE Rubber 289 greed of collectors urges them ruthlessly to cut down trees to extract all the rubber possible rather than to tap the trees in a proper manner and conserve the supplies. The increasing scarcity of rubber in accessible regions has led to efforts being made to cultivate Castilloa as well as other kinds, and very large plantations are now established in Central America. The plant, largely through the instrumentality of the Royal Botanic Gardens, Kew, has been distributed to many parts of the British Empire, including India, Ceylon, the Straits Settlements, the West Indies, Queensland, etc. In Tobago, the dependency of Trinidad, it is cultivated on a commercial scale with successful re- sults, and it has given considerable promise of being suited to other West Indian islands. In the East Indies it is at present overshadowed and put into a secondary position owing to the success which has attended the culti- vation of Para rubber, to which the energies of the rubber planters are now almost entirely devoted. It has been suggested that Castilloa would form a good tree to plant where shade is wanted for cacao, coffee, and other crops, in the place of other trees commonly so used, but which yield no useful crop. This has been done to some extent in Central America and Tobago. In some instances successful results are re- ported, in others the contrary, and it is difficult to lay down any hard and fast rule as to whether the practice is to be commended or not. Like other rubber-yielding plants, a good many years have to elapse before trees are ready to be tapped. The actual age varies in different countries, and in the same locality, with trees under varying conditions, but as a general rule it is safe to say that about eight to ten years is the average age at which tapping should be commenced. Younger trees do not yield good rubber, but a sticky material containing a high proportion of resin and of very low commercial value. The worst method of collecting the rubber is to cut down the whole tree, make deep cuts in its bark, and ex- tract every drop of latex or milk which can be obtained. This is too frequently done where the trees are 20— C.P. By permission of Messrs. Marfarev, Shoe La~te " THE REVERSED OBLIQUE SYSTEM 290 The World's Commercial Products wild and there is no check on the greed of collectors. The result is, of course, rapidly to exterminate the trees over any region, and, although high yields are obtained for a while, the supply is soon exhausted. It is the old story of killing the goose which laid the golden eggs, and the result is equally disastrous. Whenever possible this reckless waste is prevented, and more rational methods insisted on. In Nicaragua the following method is adopted as described by Belt in his interesting book of travels in that country. The collectors having found a tree, construct a rough hanging ladder from the climbing plants common in the jungle, and with the aid of this make, with a cutlass or large knife, V-shaped incisions in the bark, the points of each V being downwards. The " milk " runs out of the cuts and trickles down the trunk to the foot, where it is collected in vessels. A watery decoction obtained from the stems of a wild convolvulus is added to the rubber milk and the mixture stirred, when , the rubber coagulates and forms masses. which float on the surface. These are taken out and kneaded into flat, round cakes,, which are afterwards exported. He states that a large tree, five feet in diameter, yields, when first tapped, twenty gallons of milk, and each gallon gives 2J- lbs. of rubber. Sometimes a continuous spiral cut is made up the trunk down which the juice runs. Other modes are also adopted, but the general result is the same. The method of coagulation also varies. Thus the latex may be boiled, or spread out in thin layers on large leaves and exposed to the air, or alum may be added, the latex of Castilloa- not usually coagulating readily by itself. ASSAM RUBBER . Few plants are of greater interest to one first visiting the Eastern tropics than the Assam rubber tree, familiar to everyone from the small plants so commonly grown indoors in Great Britain and known as " Rubber plants." In its native haunts in place of a pot plant we see a tree, as tall as a large elm, with a confused and intricate network of curious buttress roots spreading over the ground in all directions, and often apparently several trunks. The latter peculiarity is due to the fact that this tree, like many other members of the fig "tribe, has the power of putting down from the branches slender roots. These, arising from a branch perhaps thirty or forty feet high, descend to the ground, looking, like pieces of smooth twine ; on reaching the ground they penetrate it, tighten up, grow very rapidly in thickness, often equalling, or even exceeding, the original trunk. As several of these aerial roots may be formed and take root, one tree may have at a later stage in its growth apparently several trunks. Like many of the tropical " Figs," it frequently begins its life as a By permission of Messrs. Maclaren, Shoe Lane FICUS ELASTICA WITH V-SHAPED CUTS 291 292 The World's Commercial Products Photo by,W. H. Johnson, Esq., F.L.S. ROLLING RUBBER seedling high up on another tree, the seeds having been deposited by a bird in a hollow or in a fork. The young plant puts down its aerial roots, gradually envel- oping and finally killing the supporting tree. The botan- ical name of the plant is Ficus elastica. It is a very close relation of the edible fig, but its fruits are small and are not good to eat. The large leaves as seen in plants grown in England are also characteristic of young plants growing wild ; on old trees the leaves are only three or four inches long, but of the same leathery character and equally glossy. The Assam rubber tree will grow in many, tropical and sub-tropical lands, but to attain its full development it requires a hot climate with a high rainfall, and thrives best in damp, tropical forests. The home of the Assam rubber tree is on the lower slopes of the great mountain ranges of northern India, in Darjeeling, Sikkim, Bhotan, Assam, and Burma. It also occurs in Java, Sumatra, and probably some of the other islands of the Malayan Archipelago. In the north of India the temperature in the coldest season of the year is too low to allow of the successful cultivation of the Para or Central American rubber trees, and experiments with those plants have not met with success. Large plantations have, however, been formed by the Indian Government in Assam with Ficus elastica, and from those of the wild plants in the forests of this region much of the rubber obtained from India is won. It is worthy of note that the common name " india-rubber " commemorates the first production of rubber from this tree in the early years of the nineteepth century. The native method of collecting the rubber is exceedingly crude and, moreover, is destruc- tive. Large wounds are made in the trunks by chopping out great pieces of the bark and wood;- and the latex is caught as it exudes. By this method many trees are permanently injured, but, as is often the case in other parts of the world also when dealing with wild plants, each collector only strives to obtain the greatest amount of rubber in the easiest way, and takes no thought for the future, so that trees are often killed.1 A method practised in the Government plantations is to make cuts with a V-shaped chisel or gauge halfway round the stem or branch. The latex or milk at first flows freely and that which drips is collected on mats made of bamboo strips, which little boys shift about on the ground from point to point as necessary. This latex coagulates, and within forty-eight hours or less can be removed from the mat and dried. Much of the latex coagulates on the tree and remains. in the cuts whence it has to be pulled out as thick elastic strings. These have to be gone over and pieces of bark, etc., removed, and subsequently dried. Finally they are forced, by the agency of a screw-press, into cubes of about 1 cwt. each, wrapped up, and are then ready to be exported. ' The mat rubber is similarly cleaned, dried, and packed in boxes. The "returns of the yield of rubber are very variable. Under the method of reckless tapping 40 lb. per tree was frequently obtained, whilst yields of over 350 lb. of rubber from single trees are reported from Burma. On plantations the yields appear small. In Assam on the Rubber 293 Government plantation in some years it has been less than 8 oz. per tr.ee, whilst sometimes rising to about 21b.; individual trees have, however, given 20-30 lb. A 'recent estimate of Mr. Gustav Mann, of the Indian Forest Department, places fifty years as the time for the tree to reach maturity, from when^ onward they would probably, yield 10 lb. of rubber at each tapping. LAGOS SILK RUBBER Lagos silk rubber is obtained from Funtumia- elastica, a medium-sized tree found wild only in tropical Africa. It will often be found referred to as Kickxia elastica, but the true Kickxias are all Malayan, whilst the Funtumias are African plants. The tree occurs in Liberia, the Gold Coast, Lagos, and Southern Nigeria; the Cameroons, and the Congo. There is some reason to believe that it is present also in Sierra Leone, but this is not quite certain. Until quite recently it was thought to be entirely confined to the West coast of Africa, but Mr. M. T. Dawe, in the course of his botanical exploration of the Mabira Forest, Uganda, found it there also, an important discovery materially altering our ideas of its geographical range. Funtumia belongs to thesame natural order as the Landolphias, and, like them, is related to our common garden Periwinkle. Its flowers are white or yellow, and the seeds are very characteris- tic, each bearing a beautiful silky plume about two inches long, by means of which they can float through the air like thistle- down, and may often be found travelling about through " West Coast " forests. The trees are tapped by making incisions in the bark, "the herring-bone sys- tem described on p. 285 being often adopted. A native climbs the tree making the vertical cut as he ascends, and the side cuts leading into it as he descends. The latex runs out and is caught in a calabash, earthenware pot, or other receptacle. It is coagulated either naturally, by application of heat, or by admixture with other latices or juices of various plants. The coagulation of pure Funtumia latex is very slow, but heat and the other methods make the process much more Photo by W. H. Johnson, Esq., F.L.S. ANCIENT PARA TREE, EAST CEYLON 294 The World's Commercial Products rapid. The rubber is of good quality, and comes on the market in " lumps " and in other forms. The collection and exportation of this rubber, now so important an industry in many parts of the west coast, is quite a modern development. As noted in the Colonial Report on Lagos for 1905, " Merchants took up the idea with enthusiasm. With startling suddenness the easy-going native awoke to the fact that wealth abounded in the forest round him and learnt for the first time that in sitting under his own fig tree he had been unconsciously reposing in the shade of the family bank." The cultivation of this rubber tree is being under- taken in West Africa, and it has also been introduced into other parts of the world, growing, for instance, very well in parts of the West Indies. CEARA RUBBER, OR MANICOBA Ceara rubber is obtained from a tree of medium size known botanically as Manihot Glaziovii, belong- ing to the Spurge Order (Euphorbiaceae). It is a very close relation of the cassava plant (M. utilis- sima), from which tapioca, amongst other products is made. The cassava plant also has a milky juice but it does not yield rubber, and it is interesting to find two such closely related plants, one yielding a valu- able foodstuff and the other rubber. A native of Brazil, the Ceara rubber plant was brought into notice in 1876, when seeds and plants were collected in Brazil by Mr. Cross and transmitted to the Royal Botanic Gardens, Kew. In the following year plants were distributed from Kew to India, Ceylon, and other colonies. The plant has been introduced into many parts of the tropics, for, like most of the other rubber plants, it only thrives in hot countries, and now it is grown in such widely separated countries as India, Ceylon, Queensland, West Africa, Zanzibar, Uganda, Natal, the West Indies, as well as in its original home. It grows with tremendous rapidity, plants raised from seed often reaching ten or more feet within one year and thirty feet by the end of the second year. Once seen, the trees are easily recognised by their spreading habit, their five-lobed, curiously bluish-grey leaves, and the bark, which peels off in thin sheets or strips, like that of a silver birch. The plant will thrive in places absolutely unsuited to most cultivated plants. Rocky and stony soils, of poor quality and 'in arid districts, present no obstacles to it, and although, setting aside Central America, but little is done with the plant at present, it is not improbable that in time it will be grown to a considerable extent on lands which are not suited to other rubber plants. Trees raised from seed Can be tapped when about four to six years old. The thin outer layers of bark are usually removed, and either the whole surface scraped sufficiently deep to allow the latex to escape, or incisions made here and there with a knife. The latex is very liquid, By permission of Messrs. Maclaren & Co., Shoe Lane TREE RECOVERING AFTER TAPPING Rubber 295 and flows readily. It coagulates on exposure to the air, and is sometimes smoked over a fire of palm nuts, as described in the case of Para rubber. In Ceylon, where the tree was planted formerly on a fairly extensive scale, the. yields of rubber were low, and little attention is given to this plant now. The greatest export from Ceylon was about 17,500 lb. in 1895, but two years later it had decreased to less than 3,000 lb. Large plantations, however, exist in Brazil, whence there is a. considerable export. The Brazilian product is exported as (1) pale yellowish brown threads, (2) small flat cakes, and (3) smoked rubber prepared like Para rubber. Ceara rubber is of good quality, although not so valuable as Para rubber. LANDOLPHIA RUBBERS The plants producing this group of rubbers are chiefly large woody climbers which in the forests of the warmer parts of Africa, often reaching to the tops of high trees and for dense, tangled masses of more or less rope- like stems. Many of them bear in profusion conspicuous jasmine-like flowers, often sweetly scented, and succeeded by large, frequently brightly coloured, and sometimes edible, fruits. They belong to the genus Landolphia of the natural order Apocynaceae. In Great Britain this order is represented by the pretty " Peri- winkles " (Vinca major and V. minor), whose stems also yield a milky juice or latex, although not rich in rubber as is that of their African relatives. Owing to their habit of growth, the Landolphias are not very well suited to culti- vation, although efforts made in this direction have met with some success. There are many species of Landolphia, but they do not all yield good rubber, and we may restrict our attention to the more important. The West Coast Species. In Senegal, Gambia, and Sierra Leone, that is, generally speaking, in the more northerly portion of West Africa, Landolphia Heudelotii is a most important source of rubber. As we proceed farther south this species is replaced by Landolphia owariensis, which is widely distributed on this side of the continent, ranging from about Sierra Leone right down to Angola. It is one of the principal rubber plants of French West Africa, the Gold Coast, Nigeria, the Congo, and Portuguese West Africa. In the Congo there also occurs Landolphia Foreti and other species. Another interesting form is L. Henriquesiana, a small shrubby plant spring- ing from underground stems or rhizomes which, when pounded, form one of the sources of " root rubber." The East Coast Species. The principal By permission ot Messrs. MacUmn & Co., Shoe Lane rubber plant on this side of Africa is Landolphia « half herring-bone " system grow ming 296 The World's Commercial Products By permission of Messrs.

Dawe has added an important new species, which he found in Uganda, and has been named L. Dawei after him. It yields very good rubber. Interestingly enough, it also occurs in the Came- roons, on the west coast. In Madagascar there are several species, of which L. Mada- gascariensis, L. Perrieri, and L. sphaerocarpa are the most important. Collection. The natives make incisions in the stems of these plants, and catch and coagulate the latex in various ways. Sometimes it is allowed to run into receptacles, and either coagulates by itself, or is induced to do so by addition of a little lime juice, or other plant juices, or by heating. At other times the native smears the milky juice over his body, peeling it off when it has formed a film. Some also hardens on the plant and is pulled away. The mode in which the various Landolphia rubbers come on the market varies considerably. If coagulated in bulk, it may be cut up into strips which are rolled up to form " twists " or " balls," or it may be exported in " lumps," in small pieces known as " thimbles," or in various other forms which we have not space to enumerate. GUAYULE RUBBER This rubber, which has recently come into notice, is obtained from a plant known as Parthenium argentatum, fairly closely related to the Sunflower of the Compositae, and is of inter- est as being the only plant in this large order known to produce rubber. Whereas the rubber plants already described are mainly trees or large woody climbers, this is a small herba- ceous plant varying, in height from a few inches to between three and four feet. It occurs principally in North Mexico on the "bush prairies," but extends also into the southern United States. The rubber contained in this plant cannot be obtained by tapping, as in ordinary rubber Rubber 297 trees, but the whole plant has to be cut down and the rubber extracted either by the vise of solvents or by mechanical methods. Very careful washing is essential, and the necessity for a large supply of water is one of the practical difficulties encountered. Factories have been erected, the largest being stated to be at Torreon, whilst there is another at'Ocampo. The crude rubber contains a high percentage of resins, over twenty per cent., but' these can partly be got rid of by proper treatment. The product is of very fair quality, although usually somewhat soft and sticky. TIMBER The United Kingdom is largely dependent for its supply of timber on other countries, and the annual value of wood imported is about £25,000,000. Deal is a name applied to a number of timbers. It is important, however, to note that originally it was not the name of a timber at all, but rather of particular sizes of certain timbers. Thus, one of the most important of European timbers is Yellow Deal, the wood of the common Scotch Fir (Pinus sylvestris), so well known in the United Kingdom, and used more extensively for ordinary carpentry work than any other timber. Vast forests of this tree occur in Prussia, Prussian Poland, Russia, Norway, Sweden, etc. The best quality for certain purposes is exported from Dantzic, having been floated'down the Vistula. At Dantzic the timber is care- fully sorted into various grades. Whole trees varying from two feet to six feet in circumference at the base are known as " hand masts " ; others less than two feet as " spars " and " poles," whilst those bigger than six feet are trimmed down and called "inch masts." From the remainder the best logs are carefully selected1 for conversion into " deals "about nine inches in width and three in thickness. Squared-up "timber of eleven inches or more in width forms planks instead of " deals." Deals are in great demand by various Governments for the decks of men-of-war, and must be practically free from sapwood. Next come ordinary planks or boards for more general purposes in which absence of sapwood is not essential. The more irregular logs are made into railway sleepers. Dantzic fir is coarse, large sticks being chiefly exported. Smaller or " milder" timbers come from Riga, Memel, whilst joiners' deals are mainly obtained from Christiania, Stockholm, Gefle, Soderham, and Onega. In the dry climate of Northern Europe fir is practically ' indestructible. White Deal. White Deal is the wood of the common spruce (Picea excelsa), which occurs over northern and central Europe, forming great forests. It is found on the mountains in the more southern districts, but grows right down to the sea level in the north, e.g., in Norway. Spruce is extensively planted in Great Britain, and there is a famous avenue of old trees known as the Cathedral Firs at Oakley Park, Ciren- cester. Burgundy pitch (q.v.) is obtained from this tree. The timber is usually white or somewhat brown, and is distinguished from ordinary deal in having no smell. It is light, soft, elastic, straight and fine grain, and has innumerable uses. The best white deals come from Christiania a mahogany tree 298 The World's Commercial Products By permission of the West Australian Agency CRIB TIME IN THE BUSH and Stockholm, and are very suitable for internal work. Inferior qualities are known as spruce deals. White Pine. The White Pine (Pinus strobus) has been for many years the most important timber tree of Northern America. It is well known in Great Britain, where it is frequently grown under the name of Weymouth Pine. The White Pine occurs throughout a broad belt stretching across North America in the latitude of the Great Lakes. The destruction has naturally been very great in a tree which has been employed for endless 'purposes for the past, two centuries, and careful attention to the maintenance of the supply for future generations is absolutely imperative. White Pine may be taken as a typical example of the " soft pines," and as it is very easily worked, has a fine, even grainf and takes a good surface, it is very extensively used as a general timber for internal carpentering and joinery work, for ship masts, and for pattern-making. Pitch 'Pine, Long Leaf Pine (U.S.A.). In the markets of Europe, the West Indies, and other parts of the world to which this timber is exported, " pitch pine " is the generally recog- nised name, but in the United States, its native country, another tree altogether, Pinus rigida, is* known as Pitch Pine, whilst "Long* Ljeaf Pine" is a commonly accepted name for P. -palustris. Pitch Pine is particularly adapted to heavy. construction work,. e.g., for bridges, building supports, railroad cars, railway sleepers, etc., etc. It is, however, apt to become " granular " under continuous cross strain. The annual output is enormous, for not only is the timber very largely used in the United States, but it is exported in constantly increasing amounts to Europe, Timbers 299 Central and South America, the West Indies. The wood is heavier and stronger than that of any other pine regularly on the market, and it is a good example of ■■■" Hard Pine." Short Leaf Pine, Yellow Pine (Pinus echinata). This good timber, tree occurs in the same region of the United States as the Long Leaf or Pitch Pine, to which it is but little inferior. It is likely, in the future to be of more commercial importance than at present. Sugar Pine (P. Lambertiana). Amongst the soft pines of North America mention should be made of the " Sugar Pine," which forms extensive forests in California and Oregon. It fills in the western portion of the United States the place occupied by White Pine in the east, and in California, for example, is extensively employed for doors, sashes,'' as-a building timber, and for general purposes. Douglas Fir or Oregon Fir (Pseudotsuga Douglasii) . is widely distributed in Canada, where. in some places it forms immense forests, and is one of the chief trees of the. western United States. Mexico is the southern limit of its distribution. The tree grows very rapidly, and the timber is hard, firm, coarse-grained and heavy, and as it can be obtained in great lengths and widths of very uniform quality, is very valuable for heavy structural work, and is extensively used in ship-building, wharf construction, spars, masts, piles, etc., and also for furniture and many other purposes. The celebrated flagstaff, 159 feet high, in the Royal Botanic Gardens, Kew, obtained from a single tree in one piece, affords an excellent idea of the possibilities of. the plant. ; The timber would be classed as a hard pine, and does not resemble white or yellow pine. A good deal has been imported into this country of recent years, but it does not find favour for joinery. Kauri PiNE There are some fifty or more kinds of ash' trees, but only one is found wild in the United Kingdom, namely, the English Ash (Fraxinus. excelsior);, which occurs also right-through Europe, in North Africa, and partsrOf Asia. Tlje'wood .known! as United States Ash in England is derived from Fraxinus americana, and North America yields other kinds such as Red Ash, Blue Ash, Green Ash, Black Ash, Oregon A.sh. The English ', Ash, gives the best timber. The white to whitish-brown wood is. moderately hard, arid. very strong, tough arid durable. In fact, in .strength and durability it conies close to oak amongst British woods. In distinction .... :. .•-_'' ( .to many woods, ash is most valuable from quickly grown trees, and the wood of young trees is practically as good as that of old trees. Hickory. Un- der the general name of hickory are included vari- ous woods from closely related trees of the genus Carya, closely allied to the walnut. This group of trees is entirely confined to North America and some four or six species contribute to the market supply of hickory. The best known characteris- tic of hickory wood is its toughness, which renders it very useful for many purposes to which ash is adapted. Boxwood. The Box Tree {Buxus sempervirms) is wild in a few- places in England, and Box' Hilb- and Boxley owe their names to this plant. It is widely distributed throughout South' Europe, North Africa, and Asia, reaching Japan and the Himalayas, and accordingly boxwood has a large number of names indicative of place of origin, e.g., English, Turkish, Coirsican, Circassian, Persian boxwood, whilst Papri is one of its Indian names. Two other species of, Buxus yield the Cape and Chinese boxwoods respectively. The box is .of very .slow growth, and "never attains a large size. The wood is very hard, dense, and close, with extremely fine grain. In seasoning boxwood -splits with a loud report and is very wasteful. In Europe it is chiefly used for turning, wood-engravirig, mathematical .. instruments; and carving and wood-working tools. Owing to the" decreasing supply of true boxwood, a very similar wood from the West Indies is largely substituted under the name West Indian Boxwood, also known as Zapatero, White Cedar, Cogwood, and by various other names. Cedar ds a name applied to a large number of timbers which are quite distinct from one another, but agree generally in being light, soft, of fine, even grain and frequently scented. Photo by N. P. Edwards, Littlehampton A BIG TREE, CALIFORNIA 307 308 The World's Commercial Products White cedars and red cedars are distin- guished according to the colour of the timber. The true cedars are the Cedar of Lebanon, the Atlas Cedar, and the Deo- dar, large trees of the Pine Order. Another well- marked group are the Cedrelas, includ- i n g West Indies, Indian and Austra- lian Red Cedars ; typical cigar-box woods. Then we have the Pencil Ce- dars, of which Vir- ginian Cedar from one of the Junipers is the chief. Various other trees are called cedars in other parts of the world. The Cedrelas are very closely related to mahogany and there is much con- fusion between this group of cedars and mahogany. Deodar. The beautiful deodar oc- our's'in the Himalayas in extensive, forests, being most abundant at elevations from 6,000 to 8,000 feet. The deodar is a " cedar," in fact the Cedar of Lebanon and the Atlas Cedar are two varieties of this plant, occurring respectively in the mountains of Asia Minor and Cyprus, and in the Atlas Mountains in Algeria. Botanists classify all three under the name Cedrus Libani. » The deodar is the principal timber tree of the. Himalayas, and yields the most useful wood of any tree in -Northern India. The sapwood is white and the heartwood yellowish-brown, strongly scented, oily, and of moderate hardness. Its chief use is for railway sleepers. Gedar'of Lebanon is frequently mentioned in the Bible, and in former times its timber was much used, e.g., in Solomon's Temple at Jerusalem large quantities were employed. WestTndian Cedar; Moulmeln Cedar, Australian Cedar. The typical West Indian and South American cedar (Cedrela odorataY is a handsome tree yielding the soft, red, fragrant wood of. which cigar-boxes, are commonly made. Cedar wainscoting is highly esteemed. Owing to the fact that it keeps very free from insects, it is used for the interior work of ward- robes, presses, etc. Havannah, Cuba, Jamaica, or Mexican cedar are other popular names of From Stereograph Copyright, 'Underwood & Underwood, 'London and. New York A' PHILIPPINE SAW MILL Timbers 309 this excellent wood. In the East Indies its place is taken by Toon (Cedrela Toona), also known as Indian Mahogany, and in England as Moulmein Cedar, from the place in Burma whence it is exported. Its wood is of the same general character and is used in India for furniture, carvings, tea-boxes, cigar-boxes. • • - *] A third species, Cedrela australis, occurs in Australia, in New South Wales, and Queensland. In the former State it is regarded as the most valuable timber tree, and is extensively used for high-class work such as carriage-panelling, etc., being equal to mahogany. ! Red Cedar or Pencil Cedar. Everyone is familiar with this wood, owing to its extensive, use in the manufacture of lead pencils. Red Cedar is widely distributed" over the North American continent, reaching its greatest development in the southern states. There are two species : the northern Red Cedar {Juniperus virginiana) -and the Florida Reel Cedar (/. barba- densis) ; the latter restricted to the coasts of the southern states and some of the West Indian islands. The red fragrant wood is light and soft, with very fine, even grain, and these. characters render it so suitable for blacklead pencils that it has been calculated that at least 150,000 trees are used annually for this purpose alone. Still larger demands are made on the tree for poles, piles, cross-trees, and other objects in which resistance to weather is important. Other uses include veneering, cigar-boxes, fancy turning, general cab- inet work, etc., and it is scarcely sur- prising that with these many uses the available supply of the tree is rapidly decreasing. A syndicate has recently obtained rights to work a very similar wood pro- duced by the allied Juniperus procera, found in the Mau Mountains in British East Africa.

Redwood is the softest timber of commerce. Although a very large tree, it is entirely overshadowed by its close relation, the " Big Tree " of California (Seguoia Washingtoniana), the largest, although not the tallest, tree in the world. Some idea of the great girth of these trees may be gained by noting that the " Mother of the Forest," felled in 1853, was eighty-four feet in circumference and accommodated a dancing party of forty-nine people on the cut stump. Canadian Red Cedar, Giant Arbor Vitae, Canoe Cedar (U.S.A.), (Thuya gigantea). A close relative of the ordinary Arbor Vitae, commonly grown in shrubberies in Great Britain, it attains a height of some 150 feet and a girth of about thirty feet. Amongst other cedars are the Pencil Cedar of New South Wales and Queensland (Dysoxylum Fraseranum), ' New Zealand Cedar (Libocedrus Bidwilli), and the allied species Libocedrus doniana, of which the native name is Kahata, and Clanwilliam Cedar (Callitris arborea). Mahogany was introduced into England about 1724. One account states that some logs were brought as ballast in a ship from British Honduras, and that owing to the hardness of the wood the carpenters refused to use it; but a box made by Wollaston, a cabinet-maker, attracted so much attention that mahogany soon became established in favour. The true mahoganies come from tropical America and the West Indies, but other woods of similar character are conveniently classed as mahogany, and we find African, Australian, East Indian, and other " mahoganies." The Central American and West Indian varieties are usually stated to be the timber of a large forest tree, Swietenia Mahagoni (see p. 297), related to the tree yielding West Indian cedar. Spanish mahogany obtained from Cuba is generally better figured, harder, and of a darker Timbers 311 colour than Honduras mahogany from British Honduras. Choice Spanish mahogany is hardly ever, used now except as a veneer. An inferior variety of Honduras mahogany, softer and of lighter colour, grows on the moist lands around the Bay of, Honduras, and is often known as Bay Wood. All these other mahoganies are^of small importance commercially in Great Britain com- pared with West African mahogany. The mahogany area of West Africa forms an irregular band, parallel to the coast from Gambia to the Cameroons. The timber is of great size, and some of the wood is most beautifully figured and fetches a very high price. Rosewood. The most important rosewood of commerce is Brazilian, derived from a species of Dalbergia, a leguminous tree. Another name for this variety is Jacaranda wood. The wood has a characteristic fragrant smell, is hard, coarse but even grained, and varies in colour from purplish. brown to black. It is highly valued as a furniture wood. Satinwood. There are two satinwoods of commerce, the one from the East and the other from the West Indies. The former is the more important and is usually known as East Indian, Tamil, or Ceylon satinwood. It is obtained from a forest tree (Chloroxylon Swietenia) which occurs in Central and Southern India and Ceylon. West Indian satinwood is very similar. in appearance to the preceding, and indeed difficult to distinguish, from it, but it usually possesses less " fire," and is almost without figure. It is derived from a species of Zanthoxylum, of the Orange family. Its curious greasy smell helps to identify it. •. * .; Ebony.

Ebenum, a large evergreen tree which also occurs in Southern India and the Malay Peninsula. The heart wood only is jet black, the sapwood being almost pure white, so that a section of an entire tree presents a most striking contrast. Andaman Padauk or Andaman Redwood. This is the principal timber exported from the Andaman Islands, the site of the great Indian convict settlement. The padauk is a very large forest tree, with a very small amount of grey sapwood, whilst the heartwood is bright red with brown and black markings. Teak. — The teak tree is one of the most striking of the commercial timber trees of the tropics, its large leaves and huge sprays of light-coloured flowers giving it a very characteristic appearance..: It attains a very large size, trees with clean stems of eighty to ninety feet to the first branch, and a girth of twenty to twenty-five feet, being recorded. The area of geographical distribution of the tree includes the greater part of India, Burma, Siam, Cambodia, Cochin China, Java, and other islands of the Dutch Indies. There are planta- tions in India and Java. The timber is of a uniform brown or yellow-brown colour, greasy to the touch, and of about the hardness of oak'. Teak is the principal wood exported from India and Burma, arid most of the supplies come to the United Kingdom. Greenheart occurs in British Guiana, Brazil, and other parts of South America. It is a very valuable, hard, heavy, tough, and elastic wood of a dark green to brown colour. Lignum Yitae is an extraordinarily hard and heavy wood obtained from Guiacum officinale, a South American and West Indian tree. It is dark brown in colour, with black streaks, but the colour- is often obscured by a sticky green gum which exudes from the cut surface. Jarrah is the hard, heavy, dark red wood of Eucalyptus marginata, a native of Western Australia. It attains a very large size, and planks of great breadth can be obtained from it. It is exceedingly durable, and is but little attacked by the boring teredo, so that it makes excellent piles. In this country it is most familiar as paving blocks. Karri is very closely related to. Jarrah, and is the timber of Eucalyptus versicolor, locally distributed in Western Australia. Mora {Dimorphandra Mora or Mora exc'elsa) is one of the largest trees of British Guiana, and also occurs elsewhere in South America. Its hard, coarse, dark brown or reddish brown timber has long been known in the United Kingdom, and is rated amongst the first-class timbers at Lloyd's for ship-building. It is said to be more durable than teak. FIBRES Photo by W G. Freeman, Esq. THE KAPOK TREE The cultivation of fibre-yielding plants and the manufacture of their products into textiles, ropes, cordage, and matting are among the most important industries of the world, and afford employment directly and indirectly to many millions of people. The industries, more- over, are of great antiquity, for we have definite evidence from the Lake Dwellings of Switzerland that flax was culti- vated and used as a textile during the Stone Age, and the occurrence of linen cloth in the Fibres 313 tombs of Egypt and constant references to the same material in the earliest books of the Bible are well known to everyone. How and when mankind first became aware of the possibilities of vegetable fibres as materials for clothing it is not easyto say, but it is not improbable that he first employed the fibres to supply his need for string and cordage, especially in his hunting expeditions, and that gradually the idea of weaving the strings to form a fabric occurred to him. The apparatus employed must have been of extreme simplicity and the finished product crude according to modern ideas ; but that thousands of years ago textiles of superlative qual- ity, rivalling anything that can be produced to-day, were manufactured by East- ern races is a matter of history and observation. The fibres employed at the present day by both civilised and uncivilised peo- ples are as numerous as the uses to which they are put, and in classifying them for purposes of description, there is choice of several alterna- tives. To the practical man, however, classifications, al- though of considerable inte- rest, are of little value. He is inclined to look upon all fibres as suitable for textiles, sacking, ropes, cordage, mat- ting, packing, and numerous -other purposes. In this ar- ticle it is proposed to deal with • the fibres from this point of view. It should be realised, however, that an absolute economic classifica- tion of uses with relation to species is impossible, since the same fibre may be used in several ways. Manila hemp, for instance, is chiefly used for rope-making, but old manila is made into paper ; cotton is used for textiles, but also, .for cordage, upholstery, and paper. In the space at our disposal it is quite impossible to describe all the fibres met with in commerce, but the most important have been dealt witfr. Cotton is of such great importance as to demand treatment in a separate article {q.v.). •*•- il iirt»i linl—MBM From Stereograph Copyright, Underwood & Underwood., London and NewjYprk^ NATIVES MAKING MATTING, MONTENEY, MEXICO FABRIC FIBRES Flax Flax was one of the earliest plants cultivated for fibre, and from the times of the first authentic record until the advent of cheaper Cotton during the last century it was. more extensively used than any other. The flax-plant, Linum usitatissimum, probably -originated in Western Asia, but at the present day it is extensively cultivated in northern and 314 The World's Commercial Products Photo by Charles Abe'niacar CARRYING HEMP central Russia, Belgium, Holland, France, Italy, Ireland, United States, and Canada, and,, next to cotton, flax is, commercially speaking, the most important fibre plant of. the world. In some countries, such as India, Central Russia, Argentina, and the United States, large areas are also under flax, but the plant is here almost exclusively cultivated as the source of linseed oil. Probably the best flax on the market is that grown in Belgium, and great care is taken in the cultivation of the crop! The principal flax-growing district is around Courtrai, where conditions are exceptionally favourable for the plant and for the preparation of the fibre. As in Ireland, flax is grown in rotation with other crops, few farmers caring to sow flax at more frequent intervals than once in every eight years, and the greatest success is obtained when the intervals are. even longer. In Ireland the plant is " pulled " or gathered when the lower leaves are beginning to fall, but in Belgium it is allowed to attain greater maturity. The greatest cafe is exercised in pulling the plant, the process being carried out by hand ; the stems are arranged so that the roots are all at the same level, and then the handfuls of the "straw," as.it is called, are piled in stooks to cure or dry. After this it is placed in ricks of bundles which are so packed together as to allow of perfect ventilation, and finally, after the seed has been removed by threshing, the straw is stacked previous to the retting process which allows of the easy separation of the bast fibre from the remaining vegetable tissue. Preparation. The retting or steeping, which depends ultimately upon the action of bacteria, is carried out in three different ways in various parts of the world. The simplest method, known as dew-retting, is that adopted in North America and Russia, where the bundles are simply spread evenly over the surface 'of 'a damp meadow, and the natural moisture of the soil, dew, and rain allowed to separate the bast from the woody tissue. In Ireland the flax is retted in pools of soft water, the pools being either natural or artificial. The sheaves are packed loosely under water so that, if possible, they do not come in contact with the bottom of the pond, and after Fibres 315 about ten days the fibre sinks to the bottom of the pond, and the process of decomposition is regarded as complete. The turbidity of the water during the whole period indicates .the activity of the fermentative organisms. In Belgium the straw is retted in the river Leys, the water of which is said to be unrivalled for the purpose. The bundles are closely packed in crates, the tops of which are covered with straw to keep out any foreign matter, and the whole is then placed in the water for from four to fifteen days. The straw is again dried in little stooks in the fields, and then subjected to a second, and sometimes a third, immersion, when the steeping process is complete. When the flax is considered to be sufficiently retted it is finally dried in the fields, and then subjected to a " breaking " process which fits it for the final scutching. The breaking is effected by machinery, and consists essentially in breaking up the stems of the plants between rollers in order to separate the woody tissue from the fibre or flax. The more thoroughly the breaking is performed the less will be the amount of scutching required, and consequently the quantity of waste material will be reduced. During the scutching process the fibre is freed from the woody particles and rendered fit for the market. Hand-scutching still survives in some coun- tries, but scutching machines are extensively employed in all the great flax-growing districts. During the process the broken stems are subjected to the action of revolving blades which beat out all the woody fragments, and, when quite clean, the finished fibre is removed to the store, and there finally baled for the market. Flax fibre is from twelve to thirteen inches in length, and varies in colour from silvery grey to yellowish white, according to the method of retting employed. It is the strongest of the commercial plant fibres, but,: nevertheless, is soft and flexible, and is extensively used for making table linen, handkerchiefs, collars, sewing thread, and bookbinders' twine.. Photo by Charles Ab&niacar THE CULTIVATION j-HEME-.: RESTING ^ OF THE UNIVERSITY OF a 316 The World's Commercial Products Hemp Many fibres are known commercially as " hemps," e.g., Sisal Hemp, Manila Hemp, and Bowstring Hemp, but the true hemp is the bast fibre of Cannabis -'saliva, a plant native to western Asia, and belonging to the stinging-nettle family. (Uflicaceae). Like flax it was -cultivated for centuries before the Christian Era, and next to flax was the most important vegetable textile material before the introduction of the cheaper cotton and jute. The principal hemp-growing countries are Russia, Austria, Italy, Turkey, China, Japan, and the United States. Throughout the -East the plant is cultivated chiefly as a source of the intoxicating drug known as " bhang." The plant reaches a height of from four to ten feet, and under especially favourable circum- stances a height of twenty feet is not uncommon. Some of the finest grades of hemp .' come from Italy, where the plant is largely cultivated,- and an account of the Italian methods of cultivation and preparation will be of interest. Great care is taken in preparing the fields for the seed, and manuring is very thoroughly carried out. The crop is considered ready for harvesting when the tops of the plants begin to turn yellow, and the male plants, which yield the best fibre, are always cut before the" female. The stems are then gathered in bundles and placed on trestles to dry, when they are ready for the next process, viz., that of retting in water. After the retting is complete the stems are carefully dried, either in the open air, a method which results in a fibre of superior colour, or else by artificial heat in ordinary bread ovens. Drying in the open air takes from three to six days, and a great point in favour of the employment of artificial heat is the rapidity with which the drying can be effected. The next process is the removal of the external bark from the stem, and this decortication, as it is called, is carried out in various ways, either by hand-beating or by the employment of very simple and primitive contrivances. The best varieties of hemp are creamy- The fibre furnishes a satisfactory substitute for flax, and, except for the finer linens, is employed for medium grades of nearly all goods commonly made from flax. It is also very largely used for cordage, ropes, and fishing-lines, and is extensively employed in the carpet and rug trades. Photo by W. G. Freeman, Esq. BORASSUS PALM white in colour, lustrous, soft, and pliable. Jute Jute is said to be yielded by several species of Corchorus, but only two species, C. capsularis ■and C. olitorius, are cultivated for their fibre. The plants are regarded as natives of India, where they are extensively grown, especially in the province of Bengal, and they are also cultivated to a limited extent in China, Malaya, and Formosa. Corchorus is a genus of the Tiliaceae (Lime tree family), and the two fibre-yielding species are annual plants growing to a height of from five to ten feet with a round stem about three- quarters of an inch in diameter. C. capsularis and C. olitorius are very similar in habit of Fibres From Stereograph] Copyright, Underwood & Underwood, London and New York MAKING ROPE IN MANILA growth, but are readily distinguished by the seed-pods, which in the case of the former plant are almost globular and in the latter cylindrical, and about two inches long. There are numerous varieties of the two species, but the fibre yielded is fairly constant in character, and for the purposes of this article the varieties will be treated of collectively. Jute grows best in a hot, damp atmosphere, and flourishes especially in a highland district. The seed is sown in the spring either broadcast or in nurseries, whence the seedlings are after- wards transplanted. Harvesting takes place about three months later, when the plants. 318 The World's Commercial Products are in flower, and the method employed is either cutting with a sickle or pulling up the whole plant by hand. The stalks are gathered into bundles and placed in stag- nant water to undergo a retting process, which is effected in varying periods of from two or three days to a month. While the bundles are under water they are examined from time to time, and, when the fibres separate readily, the bundles are taken from the water in preparation for the final separation of the fibre from the stem. Various methods are adopted, a com- mon one being for the opera- tor to beat or shake the stems in water until all the resinous matter of the bark is washed away. The man stands in the water, takes as many stems as he can conveniently hold, and strips off the bark in long strands. i ^k This completed, he dashes aLrff ' z. T - \^ the remaining fibre upon the -J^ w* ^ surface of the water until it is freed from vegetable debris, and after a further washing the jute is wrung out, dried upon lines, and finally made up into hanks ior the market. The uses of jute have been recognised in India from the most remote times, but the employ- ment of the fibre as a textile by Western peoples dates back only to the last century, the first recorded export of jute from India being in 1828. Jute is most largely used for the manufacture of " gunny " bags and cotton baling, but is also a most important cordage and twine material ; the waste material resulting from these manufactures is used in paper manufacture. Dundee is the centre of the jute industry in Great Britain. Ramie, Rhea, China Grass Ramie, Rhea, or China Grass, is an example of a product which, were it not for the difficulty and expense of its production, would probably occupy a most prominent place on the market. The fibre is without doubt one of the strongest and finest known ; it is brilliantly lustrous and silky, very durable, and is said to be less affected by moisture than any other fibre. Moreover, it is of exceptional length, and can be dyed readily. No small amount of confusion has hitherto existed with regard to the fibres variously known to commerce as China grass, ramie, and rhea, and even at the present time there is constant evidence that the confusion still exists. Briefly put, the facts are that the fibres From Stereograph Copyright, Underwood & Underwood, London and New York NATIVES MAKING ROPE, MONTENEY, MEXICO Fibres 319 K of two distinct but closely related plants are described under the three trade names given above. " China grass " is obtained from the stems of Boehmeria nivea, and " rhea," or " ramie," from the stems of a variety of this plant, B. nivea, var. tenacissima. Both plants, which belong to the stinging-nettle family, Urticaceae, have somewhat the habit of a gigantic nettle, but B. nivea flourishes in temperate countries, and is characterised by the white under- surface of its leaves, while, on the other hand, B. nivea, var. tenacissima, requires a more or less tropical climate for its best development, and has the under-surface of its leaves green. The term " ramie," however, is applied in commerce to the product of both plants. The true China grass is prepared in China entirely by hand. The first process is. the stripping off from the stem of the outer skin containing the bast. V The long strips are known technically as " ribbons," which are then deprived of the external epidermis by scraping and washing, and in the resulting product the fibres are embedded in a more or less gummy substance which it is by no means easy to remove satisfactorily. The scraped ribbons are then subjected to the " de-gumming " process, but if the fibre is intended for export this process is not carried out in China, since the merchants of Europe and America prefer to de-gum the fibre in their own mills. The hand-preparation of the fibre, however, is slow and expensive, and con- sequently numerous attempts have been made to invent suitable machinery to do the work. Large rewards have been offered from time to time, notably by the Indian Government and the Commissioners of the Paris Exhibition of 1889 for suitable mechanical processes, and at the present day the diificulty of decorticating ramie stems by machinery may be regarded as solved. There are two kinds of ramie machines, namely, those which merely strip the bark in ribbons from the stems, and those which not only decorticate the stems, but also remove more or less completely the epider- mis from the ribbons, and afford a material resembling hand-cleaned China grass. The next stage is the de-gumming process, but al- though many methods have been devised to this end, they are all more or less jealously guarded as trade secrets, and it is difficult to state the actual details of the process. Essentially, how- ever, the various methods consist in boiling the ribbons in dilute soda, and then ex- posing them to the action of bleaching powder and subsequently to that of a dilute solution of acid, until the whole of the gum has been removed. 1 tie reSUlt 01 tniS treat- From Stereograph Copyright, Underwood & Underwood, London and New V ment is the production of a load of Manila hemp at cubA 320 The World's Commercial ^Products^ a fine, white, lustrous fibre known as " filasse." The fineness and strength of ramie suggests its use for the manufacture of many materials for which cotton, wool, and flax are now employed. It is woven into goods of various descriptions such as lace curtains, handkerchiefs,, damasks, tablecloths, etc., affording a material of exquisite texture, and it has also been used for plush and carpets. Pine-Apple Fibre Although the pineapple plant (Ananas sativa, Natural Order Bromeliaceae) is usually grown for its fruit, in some parts of the East, notably in the Philippines and the Malay Peninsula, the fibre yielded by the leaves is the object of the cultivation of the plant. The plant is low- growing, and the leaves are about three feet long and one to two inches wide. To obtain the fibre, the leaves are scraped with a bamboo instrument resembling a plane, or in the Philippines merely with the sharp edge of a piece of pottery. Modern machinery, however, is also nowadays employed. The fibre obtained is washed in water and then dried in the sun. It is white, soft, flexible, and very durable, even when exposed to the action of damp. The celebrated Piha Cloth of the Philippines is prepared from this fibre, and the Chinese employ it in the manufacture of a coarse, strong fabric. The inhabitants of Formosa also use it in making some of their clothing. ROPE, CORDAGE, AND MATTING FIBRES Manila Hemp, often known as Manila fibre or abaca, is obtained from the leaf- sheaths of a non-edible ba- nana, Musa textilis, found in the Philippines. Until quite recently it was supposed that this valuable fibre was yielded by one species, but the researches of the United States Department of Agriculture have lately shown that there are probably several distinct but closely related species, all of which yield the commercial fibre. The plant is cultivated in a comparatively small portion of the Philippines, the chief districts being Luzon, Mindanao, Negros, Mindoro, Cebu, and Samar, where the humidity of the atmosphere is relatively high. The best localities are the sides of hills of volcanic origin, where good natural drainage exists, for it has been found impossible to cultivate the plant in swampy water-logged soil, or, on the other hand, in soil which rapidly becomes dry. The plant is propagated chiefly by the suckers or plantlets which spring from the roots of the mature plants. About three years are required for the suckers to reach maturity, but seedlings take a considerably longer period, generally about five years. The plants attain a height of from eight to twenty feet, the " stem " being composed of overlapping leaf-sheaths. When the flower-bud appears the whole plant is cut down close to the ground ; the leaf- sheaths are stripped off, sliced horizontally into layers about £• of an inch thick, and these in turn split into strips about two inches wide. While still fresh the strips are drawn under the edge of a blunt knife-like instrument held against the surface of a board, the process freeing the fibre from the pulp of the leaf-tissue, and leaving it clean and white. By permission of Mr. Titos. Barraclough PORTABLE SCUTCHING MACHINE Fibres 321 The finest grades of Manila hemp are of a light buff colour, lustrous, very strong, the fine fibres occurring in strands about six to twelve feet in length ; inferior qualities are coarser and duller in colour, and are lacking in strength. The fibre is regarded in the trade as unrivalled for rope -making, especially for cables, hawsers, and other marine cordage. Sisal Hemp There are two varieties of Sisal hemp met with in commerce, viz.. the sisal of Yucatan (Agave rigida, var. elongata) and the sisal of the Bahamas and Florida (A. rigida, var. sisalana). The latter, which is known as " henequen," is by far the most important, and is the subject of valuable industries in the Bahamas, Mexico, Turk's Island, Cuba, and Hawaii. Of late years the cultivation of the plant has been experimented with in India, especially in the Bombay and Madras Presidencies, and quite recently the trial plantations in German East Africa and British East Africa have produced sisal of the finest quality. The plant requires for its most satisfactory development a soil composed chiefly of lime- stone, but it does well on most stony, dry soils. The plantations are laid out from suckers as in the case of Manila hemp, or from the bulbils which appear on the flower-stalks in the positions of the withered flowers, much in the same way as "sets" occur on onion plants. The plants are set in holes during the rainy season, and practically the only attention given to the fields is the clearing away of weeds about once or twice a year. In this case it is the long sword-shaped leaves of the plant, armed with prickles along the margins, which yield the fibre, and the first crop of the outer leaves is cut at the end of the third or fourth year, according to whether the plants were grown from suckers or are " mast plants," i.e., grown from the bulbils occurring on the flowering " mast " or " pole." In Yucatan an average of about fifteen leaves is obtained annually for a period of about twenty-five years, and in the Bahamas the same number is obtained for from six to twelve years. At the end of these periods the plants send up the flowering stem, and when once the flowering is over the plants die. The machines used to separate the fibre from the leaves are generally known by their Mexican name of " Raspador," which sufficiently indicates their essential action. The leaves are fed into the machine which effectively scrapes out the pulp and at the same time washes the fibre in water which is kept running in a steady stream to remove all debris. The fibre is then hung in the sun to dry and bleach, a process which occupies about two or three days. Sisal is a straight, smooth, and clean fibre of a yellowish-white colour, measuring from two-and-a-half to four feet in length. Next to Manila hemp it is the most valuable of the hard cordage fibres. The genus Agave possesses several species yielding valuable fibres, and next in importance to the sisal plant is the American Aloe or Century Plant, Agave americana. This species, which receives its name of Century Plant from the fact that it flowers only at long intervals and Photo by W. G. Freeman, Esq. COCO-NUT YUCCA 322 The World's Commercial Products Photo by Chas. Abeniacar GATHERING HEMP then dies, is cultivated in Mexico, where it is known as " Maguey," while the fibre yielded by it is described under the native name of " pita." Istle, or Mexican Fibre, is yielded by five or six species of plants growing on the arid tablelands of northern Mexico, but the greater part of the fibre is obtained from the leaves of Agave hetera- cantha. Istle is employed in the manufacture of the cheaper grades of cordage. Phormium Fibre Phormium fibre, often in- correctly known as New Zealand Flax or Hemp, is obtained from the leaves of Phormium tenax, a plant belonging to the Lily family (Liliaceae) , and found wild in New Zealand, Norfolk Island, and the Chatham Islands. The plant is said to be unrivalled for its yield of fibre, the sword-shaped leaves, which measure from five to ten feet in length, giving upwards of fifteen per cent, of their green weight as cleaned fibre. The Maoris have long been known to prepare a most excellent fibre from Phormium by hand, and even at the present day the machine-prepared product cannot approach the native article in quality. The hand-made fibre, however, is much too expensive to be able to com- pete successfully with other commercial fibres, and in all the mills controlled by Europeans machinery is employed. The leaves are first' crushed between heavy rollers, and the soft tissues stripped off by beaters attached to a revolving drum. The fibre is then very thoroughly washed in running water, and afterwards exposed to the drying and bleaching action of the sun. After being further cleaned and straightened it is made up into hanks and baled. Within recent years the New Zealand Government has required that all Phormium fibre exported shall be graded into-defmite qualities recognised by their officials, an action designed to maintain the reputation of -the' fibre upon the world's -markets by guaranteeing to merchants an unvarying quality of the^ product. Phormium fibre is soft, nearly white in colour, with a silky lustre, and its breaking strain is stated 'to be higher than'that of either hemp or flax. ,'--■'; Bowstring Hemps These fibres, which receive their names from the fact that the natives in various parts of the world are said to prepare their bowstrings from them, are derived from the leaves of several species of Sansevieria, an important genus of Liliaceae, with representatives in the tropical regions of both the Old and New Worlds. They occur in Ceylon, on the West Coast of Africa, and in the East Indies extending from Bengal to Java and China. The most important species are 5. guineensis. ,a native of Guinea, and found in the West Indies, Central America, Abyssinia, and Mauritius ; 5. Roxburghiana, a well-known plant of India ; SV cylindrica, occurring in South Africa ; S. longiflora, a native of equatorical Africa, but now Fibres 323 distributed to tropical America, occurring abundantly in Florida ; S. ehrenbergii, found in East Africa ; and S. Zeylanica, cultivated in Ceylon. All the species are perennial, stemless plants with thick, fleshy, usually sword or lance-shaped root leaves, which yield the fibre. 5. guineensis is the best-known species producing bowstring hemp, and, as stated above, is found on the West Coast of Africa, in Central America, and in the West Indies, the principal locality being Jamaica. Mauritius, Hemp Mauritius hemp is yielded by the leaves of Furcraea gigantea, a plant belonging to the Amaryllidaceae, the natural order containing such familiar plants as the Snowdrop and Daffodil. Furcraea is closely allied to the Agaves, and like them possesses a massive long-lived stem with immense fleshy leaves ; the flowers are produced, after a long period, upon tall central stems. The plant is found throughout tropical America, but the fibre is produced commercially only in Mauritius, where the industry is most important. The preparation of the fibre involves processes essentially the same as those employed for sisal, viz., scraping, washing, and drying. The fibre is softer and whiter than other hard fibres, and is weaker than sisal. Sunn Hemp The plant producing this fibre is Crotalaria juncea, a member of the Pea family, Legu- minosae. It is a tall shrub growing from eight to twelve feet high, with a branching furrowed stem, and is extensively cultivated in India, more especially in the North- West Province's . The seed is generally sown with the advent of the rains, and it is important to sow "the seed thickly in order to avoid the bushy branching habit of the plant, which would result if abun- dance of room were allowed for development. The fibre is obtained from the stems which NEW ZEALAND FLAX 324 The World's Commercial Products are either cut with a sickle or pulled up b}' hand. Bundles of the stems cleared of the leaves are placed in water for the retting process which is complete in a few days. The operator then separates the bark and wood from the fibre in a way very similar to that employed for jute, viz., by dashing the retted stems upon the surface of the water until the cleaned fibre becomes separated. The drying is effected by hanging the fibre upon bamboo sup- ports exposed to the sun, a process which also bleaches the fibre. By permission of Mr. Thomas Barraclougli SCUTCHING MACHINE Coir Coir, or coco-nut fibre, is ob- tained from the outer husk of the coco-nut, the fruit of the coco-nut palm, a tall graceful tree from sixty to a hundred feet high, bearing a crown of large feathery leaves and spikes of small flowers. In commerce, the chief coco-nut products are oil and fibre, the latter being known to the trade as "coir." The ripe coco-nut as it occurs on the tree is a large, oval body, angular in section, and with one end somewhat' pointed ; the thick outer husk is composed of fibres densely packed together, and surrounds the " nut " so familiar in this country. In preparing coir for the market, the object is to separate the outer husk from the inner nut and to obtain the cleaned fibre. In Ceylon the husks are split open by forcing them against a pointed stick fixed in the ground. The next process is to soak the husks in water, the soaking being carried out either in pits or in brick, iron, or wooden tanks into which steam can be admitted to warm the water. Great care is taken to avoid over-soaking, but when the husks are sufficiently softened they are beaten with wooden mallets and then rubbed between the hands until all the interstitial tissue has been removed from the fibre, which is then ready for drying. In the European factories, however, machinery has been substituted for hand labour. Coir fibre is coarse, clean, stiff, and very elastic, and although not of great strength is largely used in the East as a rope and cordage material on account of its power of withstanding the action of sea-water. The screw pines also afford a useful matting material. Their leaves are cut into strips, and used for making bags, mats, wrappers, etc. " Russia mats " are made from strips of the inner bast of the Lime tree. BRUSH FIBRES An important application ot vegetable fibres in the arts is for the manufacture of brushes and brooms. In a 'few cases the stems of the plant are sufficiently fine and elastic to "be used directly for the purpose, as in the case of the Broom Millet, where the fruiting stalks are cleaned of the seed and used 'for the well-known "Venetian whisks" of Italy, and for other kinds of brushes. The roots of the Mexican grass, known to the trade as "Broom root," are also imported into Germany and France, where they are manufactured into cheap brushes and shipped to the United States. Again, the roots of Khus Khus grass, a native of India, are said to be used by the weavers of that country in arranging the threads on the loom, although the fibre is best known as the material from which the fragrant screens, or " tatties," are made. Fibres 325 Among the most important of the tree fibres used for brush-making, however, are the various " basses " or piassabas (piassavas), from which bass brooms are made. These coarse dark-brown or black fibres are obtained from the leaf -stalks or leaf- sheaths of various species of palms growing in tropical America and Africa. Bahia piassaba is derived from the leaf-stalks of a large handsome palm with pinnate leaves, abundant in swamps and on river banks in the province of Bahia, Brazil. Very little preparation of the fibre is required, for it naturally separates from the leaf -stalks in a fringe of coarse, flexible, somewhat flat strands. ' The mass of fibres is removed by the natives with a small axe, and, after a simple cleaning and straightening process, the piassaba is baled for the market. It is largely employed for the brooms used by street scavengers. Leopoldinia piassaba, a palm also found abundantly in Brazil, yields Monkey Bass or Para piassaba. The fibre, which resembles the 'former variety in essential qualities, is also obtained from the leaf-stalks, which, where they clasp the stem, become expanded and produced into ribbon-like strips and separate into fine, almost round fibres about five feet long. A fibre which is finer and more flexible than Para piassaba is that known as Madagascar piassaba, obtained from the leaf-stalks of Dictyosperma fibrosum, a palm occurring in the island. Fibres similar to those described above are afforded by other species of palms, the most interesting being the stiff, wiry, Palmyra fibre obtained from the sheathing leaf-stalks of Borassus flabellifer, a tree found truly wild in tropical Africa, and extensively planted in the East Indies, and Kitul fibre prepared from the corresponding parts of the Kitul palm, a characteristic plant of India and Ceylon. Kitul fibre is dusky brown in colour, and, after being straightened and rendered more pliable by soaking in linseed oil, is largely used for making soft long-handled brooms. The sago palm of Malacca also yields a rich black fibre remarkable for its durability and known in the East as Gomutu or Ejoo fibre. It is exten- sively used by the natives for ropes, caulking ships, stuffing cushions, etc., but only the coarsest qualities are suitable for brush-making. PAPER-MAKING FIBRES The essential constituent of paper is cellulose, and paper-makers depend entirely upon vegetable fibres for their supply of this material. There are really very few fibres which cannot be made into paper of varying qualities, the amount of cellulose they contain and the cost of manufacture being the main considerations. A large quantity of paper-making material is obtained from the waste of jute and rope-making mills, but at the present day probably the most important source of material is found in wood pulp, which is merely timber, preferably coniferous, reduced to a soft pulp by mechanical and chemical means. Esparto grass affords an- other valuable paper-making material. It grows in North Africa and .Southern Spain, occurring in dense tufts on rocky and sandy soils, and reaches great luxuriance near borassus palms Photo by W. G. Freeman, Esq. 326 The World's Commercial Products the sea-coast. There are four chief varieties, viz., Spanish, usually regarded as the best, Algerian, Tunisian, and Tripoli, the last three being in order of excellence. The paper manufactured from this grass is pliant, strong, transparent, and of great purity, but cannot compete in price with the cheap qualities made from wood pulp. A grass very similar to esparto in its paper-making qualities is the Bhabur grass of India. The straw of numerous cereal grasses is also used where obtainable, wheat, oats, and barley being employed in Europe, and rice in Asia, but the papers are of a low grade, and much inferior to esparto paper. The fibrous inner bark of the Baobab tree (Adansonia digitata) was also at one time used to a fair extent for paper, but its use has now declined. The paper used so largely by the Japanese for lanterns, umbrellas, and books of all kinds, is made from the young shoots of Broussonetia papyri/era, the paper mulberry, which is widely distributed throughout Eastern Asia and Polynesia. The plant is also interesting as the source of the famous Tapa cloth of the South Sea Islanders. Chinese rice paper is prepared from the pith of Fatsia papyrifera, a plant common in Formosa. A paper, common in India, and known as "Nepal" and "Daphne" paper, is made by the hill tribes of Nepal from the bast fibres of Daphne cannabina (D. papyrifera) , and one or two other closely allied plants. The paper is remarkably tough and smooth and has received high commendation from English experts. The " Papyrus " of the ancient Egyptians was obtained from the pith of Cyperus Papyrus, a sedge formerly largely cultivated on the banks of the Nile in Lower Egypt. The plant is. now found on the river banks of Abyssinia, Sicily, and Palestine, and is one of the principal constituents of the "sudd" or masses of floating vegetation found in the Upper Nile. The papyrus was prepared by pressing together strips of the pith previously soaked in water. The " Ola leaves " largely used as a writing material by the natives of Ceylon in former times, was prepared from strips of the young leaves of the beautiful Taliput Palm. SILKS AND FLOSSES These fibres are found attached to the seeds or the walls of the seed pods of various plants, and, biologically speaking, are intended to aid in the dispersal of the seeds by the wind. They are, therefore, very similar to cotton from a botanical point of view, but, unlike GIANT ALOE, BARBADOES Fibres 327 this fibre, they are practically useless for textile purposes since the ultimate fibres are circular in section and lack the characteristic " twist " of the cotton fibres. The most important of the silk cottons is " Kapok," the seed hairs of Eriodendron anfractuo- sum, the white silk-cotton tree of the East Indies. Various unsuccessful attempts have been made to employ it as a textile, and it is chiefly used for stuffing upholstery. It has also been employed as a buoyant material for packing life-belts. The best qualities of kapok are obtained from Java. The red silk-cotton tree, Bombax mala-paricum, is a native of India, but the floss, although of good quality, is considered to be inferior to kapok. The Down tree of tropical America and Jamaica, known botanically as Ochroma bagopus, affords a beautifully soft fawn-coloured floss, which is densely packed in the long angular pods. Cochlospermum Gossypium, an East Indian plant, also yields a good silk cotton, but it has no recognised position on the market. There are many other vegetable flosses or " silks," as they are sometimes called, and space permits the mention of but a few. The well-known " mudar " floss (Calotropis gigantea) is beautifully silky, and the natives of India affirm that it has a soothing effect when used in pillows. " Yachan " floss is obtained from Chorisia insignis in Argentina, and other flosses are yielded by species of Asclepias and Beaumontia, that of B. grandi flora, a plant growing in Bengal, being especially fine. MISCELLANEOUS FIBRES The Tapa cloth of the Pacific Islanders has been referred to under " Paper-making Fibres." The famous Uganda Bark Cloth is prepared by beating the bark of a species of Ficus with curious grooved mallets of hard wood until the debris has been got rid of and the material rendered supple. The Lace Bark of Jamaica is the bast of Lagetta Untearia, and is well known as a fancy material for cravats, frills, fans, and wall ornaments. The popular Panama hat is plaited from strips of the young leaves of Carludovica palmata, a palm- like plant growing in Central and South America. The less well-known Ippi-Appa hat of Jamaica is made in a similar way from the leaves of C. jamaicensis. The Mallow family (Malvaceae), to which the cotton plant belongs, is particularly rich in fibre-yielding plants, and some of the most in- teresting occur on the genus Hibiscus, a group of plants distinguished by their large showy flowers. " Deccan " or " Ambari " Hemp is obtained from the stems of H. cannabinus, cultivated for its fibre in most parts of India. The inner bark of H. elatus, a tree occurring in the West Indies, affords the Mountain Mahoe, sometimes known as "Cuba Bast," used for hats and for other millinery purposes. COTTON Cotton is the most im- portant material used for man's Clothing, having Photo by W. H. Johnston, Esq., F.L.S. during comparatively recent labolabo cotton farm, gold coast 328 The World's Commercial Products years almost entirely supplanted linen. Cotton, too, has successfully competed with wool, and such materials as flannelette are entirely made of cotton, whilst fabrics of mixed cotton and wool are much more common nowadays than in former times. Scientific discoveries have enabled cotton to be so treated that it appears almost exactly like silk, with the result that cotton velveteen and sateen are made on a large scale and form cheap substitutes for velvet and satin, which are made of silk. Mercerised cotton can be made to resemble silk so closely that many " silks " are so only in name. Cotton is so useful to civilised man that this one plant can supply him not only with cotton clothing, but also to a certain extent with substitutes for wool and silk. To the uncivilised races of the world, whose needs are simpler, cotton is again most important, and all kinds of native garments, ranging from the simple loin cloth of primitive people to the elaborately decorated robes of other races, are made entirely of cotton. Photo by E. Minoprio, Esq. A SOUTHERN COTTON PLANTATION, U.S.A. Cotton was well known and in common use in India long before the Christian era, for in an old book written about 800 B.C. the plant is referred to frequently, and in such a way as to show that it was quite familiar. Nearchus, the admiral of Alexander the Great, who took part of his army along the shores of the Arabian and Persian Gulf about 327 B.C., says : " There are in India trees bearing as it were bunches of wool. The natives made linen garments of it, wearing a shirt which reached to the middle of the leg, a sheet folded about the shoulders, and a turban rolled round the head, and the linen made by them from this substance was fine and whiter than any other." India was the centre of cotton cultivation and manufacture in the early days and for long afterwards. -Indian cotton goods were sent to many parts of the world, and our word " calico " was originally given to this familiar material because it came from the Indian port of Calicut. From India cotton plants were probably sent to China and other neighbouring countries. Later explorers found cotton in other regions. For example, in 1492, Columbus noted that it grew abundantlyin the West Indies and on the neighbouring coasts of America, and that the natives had considerable skill in making it up into cloth. In Mexico, Peru, and Brazil, cotton was well known and in Mexico was the chief article of clothing. In parts of tropical 329 330 The World's Commercial Products Africa } cotton grows wild, and is used by the natives to make cloths. The cotton plant belongs botanically to the Mallow Order or Malvaceae, and is closely related to the ordinary wild mallows and to the hollyhocks of our gardens. Most of the species are shrubs or small trees, and in warm countries are per- ennial. A winter, how- ever, kills the plants, and in the United States new plants have to be raised from seed every year. This prac- tice is also carried out when cotton is culti- vated in countries which have no winter, as it frequently gives better results than when the plants are allowed to grow for several years. Cotton plants have large yellow, white, or red flowers, not unlike rather small hollyhock flowers, and each flower forms a capsule or " boll." When fully ripe the boll splits into three pieces, and displays the white cottony mass, consisting of a number of seeds, each having firmly attached to it a dense covering of fine hairs, which are the raw cotton of commerce. Photo by Putnam and Valentine SHIPPING COTTON AT NEW ORLEANS COTTON-PRODUCING COUNTRIES Cotton is distinctly a warm-climate crop, and a glance at the map of the cotton-growing regions of the world shows us that it is grown in almost every part of the earth between about 40° N. and 30° S. of the Equator. In America the principal regions are the south-eastern part of •the United States, Central America, the West Indies, Brazil, Mexico, and Peru. In Europe small cotton areas are found scattered around the Mediterranean, in Spain, Italy, Turkey, and Greece. India, China, Japan, Persia, and Asia Minor are in their order the chief cotton-producing countries of Asia. In Australia cotton is onty grown to a very small extent, chiefly in "Queensland, South Australia, and New South Wales. Africa is an important con- tributor to the world's cotton supply owing to the great amount grown in Egypt ; on the west coas.t Lagos has. a considerable export, and efforts are being made to extend cotton cultivation in Nigeria and elsewhere. Rhodesia, East Africa, and Madagascar also either produce cotton or are likely to do so .in the near future. .Although, cotton is grown in. so many places, most of the world's commercial supply is obtained from three countries — the United States, India, and Egypt. The United States produce about six-tenths of the world's supply, India about two-tenths, Egypt one-tenth, and all the rest of the world together only the remaining tenth. The United States control the cotton, market, and any diminution in the supply from this source, due to a short crop or to artificial manipulation by speculators, entails grave consequences to the vast cotton industry in Lancashire. Such a shortage was brought about by the American Civil War in 1864, when the price of cotton reached a very high figure, and much distress was caused in England. Again, Cotton 331 in 1902, there was another natural shortage in the supply from America, which was made worse by the action of speculators endeavouring to form a " corner " in cotton, and mills in Lancashire had to close, or work only for part time, causing much hardship to the operatives. To endeavour to guard against the repetition of such occurrences, the British Cotton Growing Association has been formed to promote, with the co-operation of the Government, the cultiva- tion of cotton in the British Empire, and to make England to some degree independent of the American supply. More recently British cotton spinners ;have taken action With. a view to themselves becoming cotton producers in the United States. Much experimental work has been carried out with the aid of the British Cotton Growing Association in various colonies. The old cotton industry in the West Indies has been revived, due in great measure to the activity of the Imperial Department of Agriculture for the West Indies. * The dormant cotton industry of Lagos has taken new life and increased' enormously. Northern Nigeria offers immense fields if proper transport can be provided. In East Africa and various other parts of the world it has been proved that good cotton can be grown. Steps are being taken to improve the grade of cotton produced in India, which, although it now yields large crops, does not supply cotton of sufficiently good quality for the English market. The French, German, Portuguese, Italian, and Dutch Governments are also making efforts to extend cotton cultivation in their colonies, and in a few years' time it will be demonstrated which countries are able to produce cotton of good enough quality and at sufficiently low cost to compete in the world's markets with that from the present established sources of supply. Varieties There are numerous varieties of cotton, but for commercial purposes we can confine our attention to the most important. • Upland or American Cotton. This is the kind in the greatest demand. It is obtained from a plant known as Gossypium hirsutum, originally perhaps a native of Mexico, but now cultivated- in the United States and in other parts of the world. Each seed bears both long and short hairs, the latter remaining attached to the seed after the long ones are removed, so that the seeds present a " fuzzy " appearance. Indian Cottons. These are the produce of various species, amongst which G. her- baceum is the most important. The seeds have a short fuzz in addition to the longer hairs. Sea Island Cotton. The most valuable of all cottons, owing to the comparatively great length (about two inches) of the fibre, and its silky character. The seeds bear long hairs only, and are left quite clean and smooth when these are pulled off. Sea Island COtton is Photo by Putnam and Valentine often considered to be cotton on the wharf at new Orleans 332 The World's Commercial Products a native of the West Indies, but was introduced to the Sea Islands (off the coast of Georgia and South Caro- lina), where it is largely cultivated and whence it derives its common name. Recently it has been re- introduced into the West Indies. Egyptian Cottons, the more important of which are Mitafifi, Ashmouni, Yan- novitch, etc., are varieties of this same species. Kidney Cotton. The peculiar name of this vari- ety is derived from the cir- cumstance, that the seeds in each of the three divisions of the boll remain firmly attached together forming a lobed, more or less kidney-shaped mass, instead of each being separate as in the other varieties. This species yields Pernambuco, Ceara, and other kinds of South American cottons. Tree Cotton. The produce of G. arboreum, which attains a height of from fourteen to twenty feet. Africa appears to be its native home, although it is grown to some extent in India. The different varieties of cotton demand to some degree different methods of cultivation. Moreover, cotton is grown in purely tropical countries such as the West Indies, Africa, India, etc., on the inundated lands of the Nile valley, and in the United States, where the plants are annually cut down by frost. In some regions primitive labour and appliances alone are available ; in others, such as the States, the highest scientific and technical skill are to hand. All these reasons necessarily entail differences in the mode of procedure, but, as it would not be possible to describe all the variations practised in the space of a few pages, attention must be restrictedcto summarising the principal features of cotton cultivation, and the gathering and preparation of the crop until it is packed up into the huge bales so familiar a sight in the neighbourhood of the docks of Liverpool, the great cotton-receiving port of England. By permission of Messrs. Newton & Co. THE COTTON PLANT Cultivation The cotton seed is sown and the young. plants thinned out to the .distance apart best suited to local conditions. In about six months' time they flower, and the pods or bolls follow in due course. When ripe they burst, often displaying their white cottony contents. Picking is done by; hand, care being taken to harvest the cotton with as little as possible of such extraneous material as pieces of pods, twigs, dry leaves, etc. • The crop gathered is "seed-cotton," consisting of the seeds with the fibre or lint firmly attached. In primitive countries the lint is pulled off by hand. Usually, however, a gin is employed. One. type of gin has rollers between which the lint passes, whilst the seeds remain behind. There are also the saw gins, in which the lint is pulled off the seeds by a rapidly rotating toothed disc or '.'.saw.'.' As the result of ginning lint is obtained and also the cotton seed. The latter may be used on the estate or as a sourceof oil. The lint is made up into bales, compressed, and is then ready for shipment. Drugs DRUGS 333 In the present article an attempt is made to describe some of the more important vegetable products employed by man to alleviate the physical suffering of himself and of the animals which tend to his welfare. Strictly speaking, the term " drugs " includes, all substances belonging to the animal, vegetable, and inorganic kingdoms, which have been so employed, but in the space at our disposal it has been impossible to deal even briefly with any but the most important of those derived from plants. Indian Hemp. This important drug is obtained from Cannabis sativa, a plant indigenous to India and Persia, but largely cultivated in temperate parts of the world for the sake of the valuable fibre (hemp) and oil seed (hempseed). When grown in the hot regions of the tropics, the plants (especially the female plants) yield a quantity of resin possessing remarkable intoxi- cating properties, and on this account hemp is largely grown by the natives of India and the East. The drug appears in several forms in the Indian bazaars, the well-known " ganjah being the leafy flowering branches of the plant trodden and pressed by the feet into compact masses ; it is known in the English drug markets as " guaza." Ganjah is smoked like tobacco, but " bhang,"'' prepared from the dried larger leaves which are collected separately, is pounded in water to a pulp and used in the preparation of a drink. The resin itself, to which the intoxicating properties of the drug are due, is known, as " churras " or " char as" and is obtained either by kneading ganjah with the hands, or by causing men, clothed in leather garments, to brush through the living plants as violently as possible, with the result that the resin escapes from the wounded surfaces of the plants and adheres to the leather, from which it is afterwards scraped and rolled into balls. In the home market the drug generally occurs as rough, flattened resinous masses composed of the flowering shoots compacted by pressure. It possesses little taste, but has a powerful odour, and is chiefly used for its soothing properties in cases of mania and hysteria. Rhubarb. An important source of this valuable drug is probably Rheum officinale, a plant found wild in Eastern Thibet and North-western China, and now cultivated in England and elsewhere. The drug, which has long been known in Europe, consists of the dried rhizome v-m JAVA. GOVERNMENT QUININE PLANTATION 334 The World's Commercial Products or underground stem of the plant, either whole or cut into pieces of suitable length. The " roots '/. <'*re dug up, cut transversely into short pieces which are threaded on a string,. and dried in the sun or by artificial heat. Such pieces are known in the trade as ""rounds," but when too large the Chinese cut them longitudinally into two portions which are known as "flats." Rhubarb is obtained from China, and, the various names of "Turkey," "Russian," and " East Indian " rhubarb are merely relics of former times when the root reached Europe from China via the countries mentioned. Small quantities of the drug are prepared in England from R. officinale, and, to a less extent, from R. rhaponticum. English rhubarb is of excellent quality, and closely resembles the Chinese product. The drug contains -several constiuents possessing laxative properties, and is used as a purgative and bitter tonic. The well-known grittiness of the drug is due to crystals of calcium oxalate. DRYING AND PACKING QUININE Podophyllum Rhizome. The underground stem of Podophyllum peltatum is the source of podophyllin largely used as an emetic and purgative. The plant is a native of the eastern states of North America and Canada, and was long, known to the Indians as a valuable medicine. As imported, the drug consists of flattened portions of the rhizome, possessing a heavy narcotic odour and a bitter nauseous taste. The active principle is a resinous compound (podophyllin), which is precipitated from an alcoholic extract of the " root " by acidulated water. The rhizome of P. Emodi, a common plant on the lower slopes of the Himalayas, has recently been proposed as a substitute for the officinal drug. Aconite Root. The poisonous properties of the roots of the Aconite or Monkshood (Aconitum Napellus) have long been known, but it is only in comparatively recent times that the drug has been employed medicinally. The root alone is now officinal, tmt the leaves and flowering shoots were also formerly used. The Monkshood is commonly grown in England both for ornamental purposes and as a medicinal plant ; on the lower slopes of the Pyrenees, the Alps, and the mountains of Germany and Austria, the plant is very common, and is extensively collected by the peasants for sale in the drug markets. In England the drug is collected in the autumn soon after the stem and leaves have died down, and before they have d PC < 3 o © 335 336 The World's Commercial Products FOUNDING A QUININE PLANTATION begun to be depleted of their starch by the growth of new shoots, for it is at this stage that the proportion of alkaloid is generally regarded to be greatest. After the removal of the rootlets the roots are washed and dried, either whole or in longitudinal slices. The most important constituent of Aconite root;, is the alkaloid aconitine, which is used externally for certain forms of neuralgia and rheumatism. It is also used internally in cases of fever and for relieving pain, its general effect being to lower the temperature, increase the amount of urine, and to lessen- sensibility. Japanese Aconite {A. Fischeri) and Indian aconite (A. ferox) are imported into this country and contain alkaloids very similar to those of the officinal drug. Ipecacuanha Root. This drug, which has long been known in Brazil as a remedy for dysentery, consists of the thickened roots of Psychotria Ipecacuanha, a shrub growing in the shady forests of South America. Most of the supplies come from Brazil, but more or less successful attempts have been made to cultivate the plant in other parts of the world, notably in the East Indies. The slender roots, as they appear on the market, are about a quarter of an inch thick, breaking with a short fracture. The bark is markedly constricted at short intervals, and contains a large amount of starch. Ipecacuanha is largely used in dysentery, and is a powerful emetic and expectorant ; the principal constituents are the two alkaloids emetine and cephaeline. Besides the officinal drug, several varieties and substitutes are imported. New Granada and Carthagena Ipecacuanha is less active than the true root, and its botanical origin is uncertain. White or Undulated Ipecacuanha (Richardsonia scabra), False Brazilian (Ionidium Ipecacuanha), and other roots are substitutes of little, if any, medicinal value. Jalap. The ovoid tuberous roots which arise from the runners of Ipomcea Purga are Drugs 337 well known on account of their valuable purgative properties. The drug is obtained from Mexico, where the plant is indigenous, the natives collecting the tubers and drying them in nets over their hut fires ; the smaller roots are dried whole, but the larger ones are gashed with a knife in order to facilitate the process. The plant is found on the eastern slopes of the Mexican Andes, but it has been introduced into India and Jamaica where it thrives exceedingly well, yielding tubers which ,are particularly rich in the resin to which the activity of the drug is due. Tampico Jalap, distinguished from true Jalap by its irregular shape and shrunken appearance, is obtained from I. simulans, a plant also a native of the Mexican Andes. Belladonna Leaves. . The fresh leaves and branches, of Atropa Belladonna (Deadly Nightshade) are used in the preparation of extract of belladonna, a drug largely employed as an external application to relieve pain, and internally for checking excessive perspiration in consumption, for the relief of coughs, and for rnany other purposes. The extract prepared from the leaves causes the pupil of the eye to dilate, and is used in ophthalmic surgery. The principal constituents of the leaves are two alkaloids, atropine and hyoscy 'amine, but in the manufacture of these alkaloids the root of the plant is employed. Belladonna is largely cultivated in Germany for medicinal purposes, and, to a; smaller extent in Bedfordshire and Hertfordshire. The leaves are collected during the flowering period, as at this time the percentage of alkaloid is highest. •• i YOUNG PLANTATION OF CINCHONA SUCCIRUBRA 23-C.P. 338 The World's Commercial Products Coca Leaves, " Folio Cocae " of pharmacy, are the dried leaves of Erythroxylum Coca, a shrub about six or eight feet high, bearing small clusters of white flowers and resembling in- general habit the English blackthorn. Alexandrian senna leaves ft is chiefly cultivated on the (Natural size) steep slopes of valleys in the Andes, and smaller quantities are grown in other parts of the world, e.g., India, Ceylon, and Java; the market is chiefly supplied from South America. Two varieties are met with in commerce, viz., Huanuco, or Bolivian, and Truxillo, or Peruvian. The former leaves have a brownish-green colour with prominent veins, and are not broken to any great extent ; they further possess a well-marked ridge above the mid-rib. In the Truxillo leaves this ridge is absent, and the fragile broken leaves are pale- green. Coca leaves possess a somewhat bitter taste and have a slight but characteristic odour. They contain several alkaloids, the most important being cocaine, largely used in dentistry and in minor operations as a " local " anaesthetic, e.g., a substance producing insensibility to pain over the immediate area to which it is applied. The proportion of the alkaloid present is less than one per cent., and the Bolivian leaves are richer than the Peruvian variety. Coca is also used as a restorative and stimulant, but its most remarkable property is that of con- ferring remarkable powers of resisting physical and mental fatigue. Comparatively but a small proportion of the coca leaves collected in South America is exported, the bulk of the crop being used by the Indians for the purposes mentioned. The custom is one of great antiquity, and the dried leaves have become almost indispensable to the people. The leaves are chewed, mixed with lime and the ash of a plant closely related to the goosefoots of our fields and waste places. When taken in excess the drug is said to produce an intoxication similar to that of opium in its effects, and slaves to the coca-habit seldom attain to old age. Senna Leaves are obtained from two species of Cassia, a genus belonging to the Legumi- nosae (Pea family). " Alexandrian senna " consists of the leaflets of Cassia acutifolia, a small' bush growing wild in several districts of Egypt. The leaves are collected by the Arabs chiefly between Suakim and Kassala, the most important of the two harvests taking place after, the rains in September. The plants are cut and then spread out in the sun to dry, when the leaflets are removed from their stalks. The drug is then packed in palm-leaf bags and carried down for export either to the Red Sea ports or down the Nile to Alexandria. At one time the trade in senna was a monopoly of the Egyptian Government. Indian or Tinnevelly Senna consists of the leaflets of Cassia angustifolia, which is abundant in Southern Arabia. The plant is largely cultivated for medicinal purposes in the Tinnevelly district of Southern India, whence the drug receives its name. The leaflets closely resemble Alexandrian senna, but are larger, somewhat narrower, of a lighter green colour, and less hairy ; an interesting difference between the drugs as they appear on the market is the flatter condition of Tinnevelly senna leaves, due to the fact that the leaves are pressed into bales before being shipped, whereas the Arabs pack the drug comparatively loosely. Both, varieties. of- senna are extensively used as a purgative in the form of an infusion, and as an'irigredient of " confection of senna." Colocyntii or Bitter Apple. The spongy, intensely bitter pulp of the dried fruit of Citrnllus Colocynihis, a creeping plant belonging to the Cucumber family, is largely used as a powerful purgative". .The plant is regarded as a native of the warmer districts of Asia, but it is now widely "distributed, occurring abundantly in Egypt and Northern Africa ; it is also common on the shores of Portugal and is found in Syria, Persia, and India. The fruits, which resemble an orange in shape and size, are green when fresh, but become yellowish-brown when Drugs 339 dried. They are collected when ripe and the thin rind removed with a sharp knife, leaving the white pulp containing a large number of seeds. The drug consists of white balls about two inches in diameter, and generally more or less broken. They are extremely light in weight, and the seeds themselves constitute about three-quarters of the total weight. The "Turkey" and "Spanish" colocynth . are the principal varieties met with, and;:the former commands the highest prices, though there is no reason to suppose that it possesses more active properties. The action of colocynth is due to an intensely bitter substance, colocynthin, occurring only in the pulp which alone is used in medicine. " Mogador " colocynths, from which the rind has not been removed, are also imported, and are . commonly used by druggists for show purposes in window-dressing. Nux Vomica. The seeds of Strychnos Nux-vomica have long been known as a valuable drug, though for some time after their introduction into Europe in the sixteenth century they were chiefly used as a poison for dogs, cats, and vermin. The tree is a native of the Coromandel Coast of India and Cochin China, and is also found in Ceylon and North Australia. The fruit closely resembles an orange, and contains usually from three to five seeds embedded in a bitter whitish pulp. The grey, disc-shaped seeds, which are closely covered with fine silky hairs, are about the size of a halfpenny, and somewhat thinner at the centre than at the circumference. They are extracted from the pulp, and then washed and finally dried in the sun. They are exported chiefly from India, the chief ports being Madras, Bombay, Calcutta, and Cochin. The dry seeds possess an intensely bitter taste and are very hard. They are extremely poisonous on account of the presence of two alkaloids, strychnine and brucine. The drug is extensively used in small doses as a valuable tonic and in the treatment of certain forms of paralysis and other nervous diseases. In large doses it is a virulent poison. Cola or Kola Nuts. These nuts, also known as Bissy or Gooroo Nuts, have long been highly prized by the natives of tropical Africa and elsewhere on account of their stimulating and sustaining properties when chewed. The white or crimson nuts occur five to fifteen together in large woody fruits ; they are deprived of their seed-coats and masticated while fresh. There are two varieties of Cola nuts on the market, viz., the kernels of Cola acuminata and C. vera. The former nuts possess four cotyledons, while the latter, which are the most valuable, possess only two. The most important consti- tuent of the drug is an alkaloid, caffeine (also found in coffee), and a small amount of theobro- mine is present. It is to these substances, chiefly the former, that the drug owes its stimulating properties, which cause it to be used in medicine to prevent fatigue and as a nerve stimulant. Areca or Betel Nuts. Areca or Betel Nuts are the seeds of Areca Catechu, a palm largely cul- tivated in India, Ceylon, and Malaya. The " nuts " are enclosed in the outer fibrous shell of the fruit, which resembles an egg in size and shape. They are bluntly conical, about an inch long, and, in section, exhibit a mottled appearance, the white endosperm being traversed by wavy, dark- brown lines which are due to ingrowths of the seed coat. The nuts are used in this country for destroying Photo by Wt G. Freeman< £s(7. worms in dogs, but by far their most important aloes 340 The World's Commercial Products use is in the East, where they are in universal demand among the natives as a masticatory or chewing material. For this purpose the nuts are cut into thin, narrow slices, which are rolled up with lime in leaves of the betel pepper (Piper Betle). The mixture has a hot and acrid taste when chewed, and its immediate effect is to increase the flow of saliva, which is turned a brilliant red colour. The teeth of the consumer are also stained, but there are said to be no evil results of the habit, which is so firmly established among the natives " that they would rather forego meat and drink than their favourite areca nuts." - The importance of the trade in the nuts may be judged from the fact that, in Ceylon alone, the export trade in 1905 was valued at considerably over £100,000 sterling. BARKS AND WOODS Cinchona Bark is the source of the invaluable alkaloid quinine, so largely used in the treatment of fevers. The medicinal value of the bark first became definitely known in 1638, when the Countess Chinchon, wife of the Viceroy of Peru, was cured of fever by use of an extract of the bark, and it was not long before the drug became recognised in Europe as a valuable febrifuge. Cin- chona bark is obtained from several species of Cinchona, a genus of trees belonging to the Rubiaceae found truly wild only in South America, but now extensively cultivated in Java, India, Ceylon, and, to a smaller extent, in the West Indies and tropical Africa, whence the drug is now chiefly obtained. The commercial supplies of the drug are obtained from the following species of Cinchona, the first three of which are the most important : — C. Ledge- riana, C. Calisaya, C. officinalis, and C. succirubra. The method of collecting the bark which is becoming generally adopted at the present time is known as " uprooting." As the name indi- cates, the trees, as soon as they have • reached the period of growth when the bark contains the maximum amount of quinine, are grubbed up, and the bark stripped from the trunk, branches, and roots, the root, bark being especially rich in the alkaloid. The land is then replanted. A method which has met with considerable success in India consists in removing the bark in alternate longitudinal strips and covering the wounds with damp moss or litter in order to allow a new bark to develop on the exposed surface. Analysis shows that the secondary bark is richer in quinine than the "natural" bark, and is, therefore, of greater commercial value. A third method, known as the "shaving," is a. modification of that just mentioned, and consists in removing only the outer part 'of the bark by shaving with a tool, so that the " renewed " bark may be formed without the necessity. of binding damp moss round the tree. The South American method, as stated above, -is to fell the tree and strip off -all the bark, subsequently drying it in the sun or over. fires. The larger pieces are pressed under heavy weights and constitute the "flat bark '\ of the trade,. while the thinner'bark of the smaller branches is known as " quilled bark," on account of its rolling up into quills while drying. The finer qualities of quills are obtained from the young branches which arise from the crowns of plants which have been coppiced. BELLADONNA Showing leaves in unequal pairs (reduced) Drugs 341 The principal constituents of Cinchona bark are alkaloids, of which the chief are quinine, cinchonidine, cinchonine, and quinidine. The value of a bark is estimated according to the quantity of quinine present, the average amount varying from 30 per cent, to 5'0 per Cent, in " Ledger " bark (C. Ledgeriana), from 3'0 per cent, to 40 per cent, in Calisaya bark (C Calisaya). Quinine is chiefly used in the treatment of fevers, and as a tonic ; the barks are too bulky for general use, except as bitter stomachics and tonics. The drug has a well-known intensely bitter taste, but a form is now prepared which is tasteless. It would be difficult to over-estimate the value of quinine to the white man in guarding against and withstanding the attacks of fever, especially malaria, in the tropics. As an instance of its recognised value it may be mentioned that the Indian Government has ordered that the drug, put up into small pice packets, shall be on sale at every post-office throughout the country, so that the remedy may be within the reach of all, even the poorest. Cascara Sagrada. Cascara Sagrada ("sacred bark") is a valuable medicine used in small doses as a tonic, and in larger quantities as an aperient and purgative. It is the bark of Rhamnus Purshiana (a small tree closely allied to the English Buckthorn), which is found in abundance in certain of the United States of America. The bark occurs in commerce in the form of quills and flat portions, which are removed from the tree in the spring and summer, especially after a spell of rainy weather. The inner - surf ace of the bark is of a reddish-brown colour, while the outer surface is frequently covered with lichens. The chemistry of Cascara Sagrada is by no means well known, but the principal constituents appear to be emodin, frangulin, and purshianin, which possess purgative properties. The drug has a slight odour but a very bitter taste, and is in such demand that the cutting of the trees has recently been re- stricted by law in order to avoid extermination. Guaiacum Wood. The heart- wood of Guaiacum officinale and G. sanctum contains a dark-coloured resin used in the preparation of a tincture employed in the treatment of gout and rheumatism. The wood itself is an ingredient in the com- pound decoction of sarsaparilla used in the treatment of syphilis. The drug is principally obtained from G. officinale ("lignum vitse " of com- merce), an evergreen tree occurring in the West Indies and South America ; supplies are principally obtained from Cuba and Hayti. The vessels and other elements of the heart-wood are filled with a dark resin which, when exposed to the action of oxidising agents, assumes a blue colour. Quassia Wood. The wood of Quassia amara, a tree native to South America, first became used in medicine about 1750. Later it was found that the wood of Picraena excelsa possessed almost identical Photo by W. G. Freeman, Esq. THE KOLA TREE 342 The World's Commercial Products properties, and in England has been adopted as officinal in place of Quassia wood, which is still retained on the Continent. Picraena excelsa is a tree of medium size common in the lower country of Jamaica. The wood is entirely- without odour, but possesses an intensely bitter taste. The chips and shavings of the wood are used in the preparation of a bitter tonic. EXTRACTS Opium. This drug, so well known, even in remote times, for its valuable sedative properties, is the dried milky juice or latex obtained from the walls of the unripe seed capsules of several varieties of Pap aver somniferum, the Opium Poppy. The narcotic properties are due to the presence of certain alkaloids, the most important being morphine, and, to a less extent, narcotine and codeine. Opium is prepared chiefly in Turkey, India, Persia, and China, but excellent qualities have been obtained from European experimental plantations, notably in France ; the cost of production, however, renders the preparation of the drug in Europe commercially impossible. As is well known, the industry is of great importance in India, where, except in the Native States, it is under strict Government control. The method of collecting the latex is practically the same in all countries. While the capsules are still unripe, incisions are made in their walls with a small instrument so constructed that it is impossible to penetrate to the seeds, which would prevent them ripening and thus spoil them as a source of oil. (See " Oils and Fats.") The latex immediately exudes and soon begins to coagulate. Next morning it is scraped off with a knife and the damp pinkish mass placed in sloping dishes to drain. When this is completed, the opium is allowed to partially dry in the sun, when it is ready for packing. The high price of the drug naturally results in its frequent adulteration. Besides seeds, charcoal, and ground poppy petals, such crude adulterants as shot, sand, mud, and pieces of metal are sometimes added to increase the weight. The bulk of the opium reaching this country is imported from Persia and Turkey. As is well known, practically all the Indian drug exported goes to China, but the latter country imports large quantities overland from Persia, and in recent years has made great strides in the home production of the drug. The universal use of opium as a narcotic in China needs no more than passing mention. Aloes. Aloes is the dried juice of the leaves of certain species of Aloe, a genus of plants belonging to the Lily family, and indigenous to South and East Africa, but now introduced into the West Indies and other tropical countries. The four principal varieties of the drug are " Curagoa aloes " (commonly known as " Barbados aloes "), obtained from the leaves of Aloe chinensis ; " Socotrine aloes," obtained from A. Perryi, in the island of Socotra, and the east coast of Africa, whence it reaches this country via Bombay ; " Cape aloes " and " Natal aloes," obtained from several South African species of Aloe, one of which is probably A. ferox. A large proportion of the supplies of the drug come from the Dutch West Indies, chiefly Curacoa. The juicy leaves are cut from the plant and immediately placed with their cut ends downwards in sloping troughs placed at convenient intervals on the field or planta- tion. The juice rapidly exudes and is collected in gourds or tin boxes through an aperture at the lower end of the trough. It is then taken to the boiling house and evaporated in copper pans until it becomes a thick, black, viscid mass. When of the right consistency, the aloes is poured into jalap root gourds or boxes where it cools and solidifies. Drugs 343 \A^A ■Jfc On some estates, the evapora- tion is effected by steam- heaters. As stated above, Curacoa aloes is frequently described as "Barbados aloes" from the fact that in the early part of last century the bulk of the drug from the West Indies came from the British island. The trade, however, has almost disappeared, and at the present day the drug is produced on only one estate. The plant cultivated is A . vera. The famous Socotrin aloes is prepared by much cruder methods. The juice is col- lected in goatskins placed in shallow hollows scooped out in the ground, and allowed to partially evaporate in the sun. It reaches this country as a pasty or even semi-fluid mass which is dried at a gentle heat before use. Cape and Natal aloes is prepared in a way similar to that adopted in the West Indies. The appearance of the drug when it reaches the market is largely dependent upon the methods employed in its preparation. When the juice is rapidly concentrated and quickly cooled, the mass breaks with a glassy or vitreous fracture as in Cape and Curacoa aloes (" glassy " aloes). When evaporated slowly the mass becomes dull and opaque, and is known as " livery " or " hepatic " aloes, as in the case of the drug from Socotra, Zanzibar, Natal, and, in some cases, from Curacoa. Aloes is used as a purgative, and is one of the most valuable of this class of drugs. Its action is due to the presence of the crystalline, bitter principle aloin. ■*:il3<&% * Photo by W. G. Freeman, Esq. ALOES GUMS AND RESINS BALSAMS, BALSAMIC RESINS, AND GUM-RESINS These products are usually of little commercial importance, and they are almost wholly used in medicine. The most important of the balsams and balsamic resins are storax, benzoin, the balsams of Tolu and Peru, and Dragon's blood (obtained from the fruits of a rattan palm {Calamus draco) growing in Sumatra and Borneo, and used chiefly as a red stain for spirit varnishes. The best known gum-resins are myrrh, olibanum or frankincense, galbanum, asafcetida, and ammoniacum. Many drugs are used for the sake of the resins they contain, these not being exuded by the plant but secreted in roots, leaves, etc., from which they must be extracted by chemical processes. GUMS The term gum is loosely applied in commerce to a number of different products, which are better classified into the following groups : — 1. True gums, such as Acacia gum, Tragacanth gum, etc. 2. Varnish resins, such as "Gum dammar," " gum copal," etc. 3. Balsamic resins, such as "Gum benjamin or benzoin," etc. 4. 'Gum-resin's, mixtures of gum and resin, such as " gum myrrh," "gum asafcetida," etc. 5. Dried4 -plant juices, such as " Gum opium " and " gum kino." 344 The World's Commercial Products The true gums, which alone will be dealt with in this article, are readily distinguished from the products included in classes 2 to 5, and wrongly, called gums, by the possession of the following characteristic properties: — 1. They are soluble in water, yielding clear viscid or jelly-like solutions. 2. They are insoluble in alcohol. 3. They are almost tasteless, or have at most either a slightly acid or slightly sweetish taste NATURE OF GUMS The process by which true gums are produced- in plants is not as yet thoroughly known. They appear to be formed by the progressive breaking down (gummosis) of cellulose, but practically nothing is known as to how this "breaking down "is accomplished. GUM ARABIC This is a generic name including practically all gums, which are soluble in water to form Photo by T. G. Hall, Esq., F.L.S PINE TREES viscous sticky solutions possessing the properties of ordinary "office gum." Gums of this type are largely produced in the Anglo-Egyptian Sudan, Abyssinia, Somaliland, Nigeria, Senegal, India, Australia, and Cape Colony. Turkey or Sudan Gum This rnaterial is produced in the several countries forming the North-eastern horn of Africa. It has been an article of commerce from very early times ; there is evidence that as early as the first century of the Christian era gum was shipped from Egypt to Arabian ports and thence sent to Europe, hence the designation " gum arabic " now loosely applied to all gums of this type. In the Middle Ages the trade in gum between Egypt and Europe was carried on via Turkish ports and hence the name " Turkey gum" still in use, though the trade via Turkey has long since ceased. This fact is slowly being recognised by a change in name, and the gum is now frequently referred to commercially as " Sudan or Kordofan gum." Gums and Resins 345 From Stereograph Copyright, Underwood & Underwood, London andTNew York GATHERING CRUDE TURPENTINE, NORTH CAROLINA Three kinds of gum are largely produced in the Anglo-Egyptian Sudan, and these are known in the country as " Hashab " or "Verek," " Gezira," and "Talh" gums. Hashab. The "Hashab" tree of the Sudan is known scientifically as Acacia Senegal. It is plentiful in Kordofan, where the best qualities of this gum are produced, and is also fairly widely distributed in Kassala and Gezira. The gum produced in Kordofan is collected from trees grown in plantations known as " genenas." These trees are raised from seed and 346 The World's Commercial Products begin to exude gum in the third year of growth, when they are from eight to ten feet high, and have a maxi- mum girth of from six to eight inches. They continue to produce gum until the fifteenth year, when it is advisable to renew them. The best yields are obtained from the eighth to the twelfth years of growth. "Hashab Wady" is the name applied to gum which is exuded naturally from "hashab" trees not in- cluded in the " genena," and is usually in • pear- shaped pieces of ' variable size depending on the length of time between consecutive pickings. Most Of the gum exported is merely cleaned, but a small quantity is " selected " and " specially dried." For this purpose nearly colour- less " tears " are selected from the crude " hashab'' and exposed on the sand along the banks of the Nile to the sun. After a few days of this treatment they become white and almost opaque, due to the production of innumerable cracks as the result of the drying. This gum fetches a higher price than the crude mixed material. For most purposes to which gum is applied in commerce, the crude unselected " hashab " is suitable, but for a few purposes " graded " or " selected " gum is required. The " selection " of gum is principally done in European centres of trade, such as Trieste, London, and Hamburg. Senegal Gum. The " hashab ". tree- (Acacia Senegal), from which Sudanese gum is principally derived, occurs right through the fertile belt of territory (the Central and Western Sudan), which stretches across Africa below the Sahara. On the north bank of the Senegal vast forests of Acacia Senegal occur stretching away into the hinterland. This region is inhabited by Moors and other wandering peoples who employ their slaves and probably also their prisoners of war in the collection of gum. No system of cultivation such as that adopted in the " genenas " of Kordofan is attempted in Senegambia or its hinterland. During the rains the forests are converted into swamps and "the trees become gorged with sap. After the rains have ceased the scorching east wind known as the Harmattan prevails, and this rapidly removes the excess of water ; the barks of the trees become fissured in all directions and through these fissures the gum exudes as a thick liquid, which rapidly dries into " tears." From Stereograph Copyright, Underwood & Underwood, London and New York DISTILLING TURPENTINE, NORTH CAROLINA / Gums and Resins 347 Wattle Gums The wattles are a group of acacias indigenous to Australia, where they are largely exploited for their barks, which are rich in tannin (see p. 352), and for their soluble gums. Several of the wattles have been introduced into South Africa, where they are cultivated for bark, gum being collected from them as a bye-product. The principal Australian species yielding gum in notable quantities is Acacia dealbata. Cape gum is obtained from Acacia horrida. Indian Gums Two varieties of gum are exported from India, viz., " East Indian gum," already alluded to, which consists essentially of Somaliland gum mixed with true Indian gums, and Ghati gum, so named because it is collected spasmodically by the natives inhabiting the western Ghats. The Ghati gum which reaches this country is tolerably uniform and is probably collected, principally from Anogeissus latifolia. It is usually of pale colour and possesses special properties, which have secured for it a prominent place as a substitute for Sudanese and Senegal gums, especially in the United Kingdom. RESINS The commercially valuable resins are, as explained in the article dealing with gums, known in commerce as gums, e.g., " gum copal," " gum dammar." They are readily distinguishable from true gums by being soluble in spirit or oils, but ^ " not in water. They also differ from gums in their mode of formation in plants thus, whilst true gums are apparently decomposition products of cellulose, resins appear to be elaborated by plants from certain constit- uents of the essential oils. It follows from this mode of formation that resins usually occur in plants associated with essential oils, thus " common rosin " occurs in special ducts in pine trees dissolved in oil of turpentine, and similarly fresh copal and dammar usually contain small quantities of the essen- tial oils from which they were probably originally formed. The resins of com- merce may conveniently be divided into four classes : — 1. Varnish resins. These are usually hard substances containing either no essential oil or very small quantities of such volatile products. Ex- amDleS * CODal dammar San- From Stereograph Copyright, Underwood & Underwood, London and New York darac, mastic. 2.0leo-resins. the resin market, savannah, Georgia 348 The World's Commercial Products Mixtures of essential oil and resin. These are usually vis- cous liquids or semi-solids. Examples : " Balsam of Copaiba," wood oil, elemi, Canada balsam. 3. Balsams and balsamic resins. These may be either liquids such as " balsam of Peru " or solids such as " benzoin." They contain either benzoic or cinnamic acid, and the pres- ence of one or both of these acids or their compounds confers on them their peculiar " balsamic " odour. These true " balsams " should be distinguished from such pro- ducts as copaiba and Canada " balsams," which are really oleo-resins. 4. Gum-resins. These are mixtures of true gums with resins and may also contain some essential oil. Examples : Myrrh and asafoetida. Copals The copals are a class of hard resins used in the pre- paration of elastic varnishes suitable for outdoor use, as, for example, on railway carriages. They are derived from many different trees and are procured from several countries. They are always very hard, melt with difficulty, are usually insoluble in all solvents and are only convertible into varnishes by a preliminary process' of destructive "distillation. In all the localities in which, copal is produced, three qualities are generally put on the market : — 1. Fossil Copal, found in the ground usually in districts from which copal trees have entirely disappeared. 2. Semi-fossilised Copal, collected from the soil in the neighbour- hood vof living', copal trees. 3. Fresh Copal, found on • living trees either as the result of exudation through natural fissures'* or from "artificial incisions. Of these three kinds the first is of most value, " fresh copal " being of little value in European markets. East African Copals. These are also known in English commerce as " animi resins or gums." They are found "in a fossil condition in Zanzibar, Madagascar, and along the East African coast from the third to the tenth parallelof latitude. American Copals. These are collected in South America and probably originated from Hymenaea Courbaril, a tree closely related to that supposed to have produced the East African copals, which they resemble in character, though they are somewhat softer. Kauri or Cowrie Copal. This variety is produced wholly in New Zealand, whence enormous By permission of Zealand GoveriinuiU A KAURI TREE Gums and Resins 349 quantities have been exported during the last sixty years. The resin originally exuded from the Kauri pine (Dammara Australis), forests of which still exist in New Zealand from which " fresh kauri " is collected to a small extent. Oleo-Resins Turpentines. By " turpentine " is usually understood in this country the familiar colour- less liquid used for many domestic purposes. This product is more accurately called " oil of turpentine " since it is produced by the distillation of the crude " turpentine," which exudes from pine trees. " Turpentine " is chiefly obtained from Pinus australis in the United States, Pinus pinaster (maritima) in the Gironde district of France, and Pinus sylvestris in Russia. In the United States preparations for the collection of " turpentine "•■ are made in winter. Three pocket-like cavities, each capable of holding about a quart, are cut in the trees at a distance of 6 to 12 inches above the ground. The " turpentine " which exudes from incisions periodically made in the tree accumulates in these cavities, and is ladled out from time to time by the collectors. Some of the turpentine dries on the trees ; this is scraped off and forms the material known in com- merce as ''common frank- p incense." The "turpentine" is then transported to central factories for distillation, the distillate being \ oil of turpentine " and the resi- due " common rosin " or " colophony." TANS AND DYES The operation of "tanning" consists in the conversion of hides and skins into leather. This change is effected by the use of certain vegetable products called tanning- materials, which contain a peculiar compound known as tannin, having the prop- erty of combining with the substance of hide and skin forming leather, thereby con- verting a material which readily decays into one which is proverbially resistant. Nature of Tanning Materials Tannin occurs in all parts of plants, but it appears to be most secreted in those portions which are of rela- tively little use to the plant as a living agent, viz., the HEMLOCK SPRUCE 350 The World's Commercial Products OAK TREE bark of the stem or root, the rind or husk of the fruit, or the heart-wood, though in a few cases it occurs in large quantities in the living parts of plants, e.g., in the leaves and roots. As a general rule a part of a plant is unsuitable for use as a tanning agent unless it contains at least ten per cent, of tannin, though this alone is not sufficient to give a material value for this pur- pose ; it must in addition contain non-tannin extrac- tive matter, which is useful in producing what tanners call a " well-filled " leather. It must further be free from dark or undesirable colouring matters, as otherwise the value of the leather produced will be prejudiced by its colour, which should be at most a pale russet-brown. Though it is not customary to use tanning agents containing less than ten per cent, of tannin, a method has been devised for the utilisation of such materials as oak-wood and chestnut-wood, which contain only three or four per cent. This consists in extracting from these the whole of the soluble matter they contain and concentrating this extract till it solidifies. In this way " tanning extracts " containing as much as thirty per cent, of tannin may be obtained from oak-wood. This process, first devised in order to facilitate the exploitation of materials poor in tannin, has, during the last few years, been greatly extended until at the present time practically all important tanning materials can be bought in the form of extracts. At first the manufacture of these was confined to the industrial countries in which leather manufacture was principally carried on, but lately the tendency has grown to make these extracts where the tanning- materials are produced. In this way the exporter pays transport charges only on the material actually used by the tanner and can use the inert matter left after extraction as fuel and in other ways. Tanning Materials derived from Oaks t - Oak Bark. This was at one time practically the only tanning material used in the United Kingdom for heavy leathers, but of recent years its use, though still very large, has become more restricted owing to the fact that the bark is expensive as a tanning agent and cannot compete in price with many materials of exotic origin now available. Oak bark is a bye- product of the oak timber industry, and is only collected from felled trees. The trees are usually cut down from April to June, and the bark is at once detached, roughly cleaned from lichens, moss, etc., and dried. If is sold either in pieces about a yard long (" long rind bark "), or is chopped into. small pieces ("hatched bark"). English oak bark contains from twelve to fifteen per cent, of tannin, and is richest. when collected from trees from thirteen to twenty five years old. . A good deal of oak. bark is also obtained from Belgium, Holland, France, and Sweden}! the. Belgian -being considered the. best' of "these, imported varieties. Oak-wood. The heart- wood of the common oak contains from two to five per cent, of tannin, and is therefore unsuitable for use in the crude state. The sawdust, shavings, and waste pieces are, however, utilised, as already described, for the manufacture of "oak-wood extract," Tans and Dyes OF THE UW'VERSITY 351 which contains from twenty -six to thirty per cent, of tannin. This is principally made in Hungary and Italy. Galls. These are excrescences produced on the gall oak (Quercus tinctoria) as the result of punctures made by the " gall insect." They contain forty to fifty per cent, of tannin, and are used principally in the manufacture of ink. Valonia. This consists of the acorn cups of the valonia oak {Quercus aegilops), which occurs widely distributed in Asia Minor and the Balkan Peninsula. The cups are picked by hand after the acorns have fallen and are simply dried in the sun. Valonia contains from twenty -five to thirty per cent, of tannin, and is used for the production of sole leather, for which purpose it has largely replaced oak bark in the United Kingdom. Tanning Materials obtained from Coniferous Trees A considerable number of coniferous trees yield barks suitable for use in tanning. In Scotland the bark of the larch (Larix Europaea) is employed ; it contains about nine per cent, of tannin, and is valued particularly for light leathers. Throughout Austria the bark of the Norwegian spruce is commonly made use of ; it contains about eleven per cent, of tannin, and yields a plump, nicely coloured, but rather poorly filled leather. Considerable quantities of tanning extract are now made from spruce bark in Austria for export. The same spruce grows commonly in the United Kingdom and in Scandinavia, but, curiously enough, in spite of the large supplies of the bark which must be available in Norway and Sweden, it is but little used in those countries. " Hemlock Bark.'''' This is obtained from the " hemlock " fir (Abies canadensis), a tree widely distributed in Canada and throughout the northern part of the United States, in which countries it forms the staple tanning material. The bark contains from seven to ten per cent, of tannin, and yields a plump, rather reddish leather. Hemlock bark is a bye-product of the timber industry, and as disafforestation is rapidly proceeding in the United States, the bark is becoming scarce. There are, however, large forests of hemlock fir in Canada, and there the bark is used in the local tanneries, but probably a much larger quantity is converted into " hemlock extract," which is imported into European countries and the United States. The Canadian extract contains from twenty-eight to thirty per cent, of tannin. Birch Barks These are also products which are fairly extensively used in several countries, but are too poor in tannin to be worth export. White birch bark (Betula alba) is collected and used to a small extent in Scotland and is employed on a considerable scale in Russia. The bark contains about ten per cent, of tannin and in addition a small quantity of a pleasant-smelling volatile oil, which is absorbed by hide. It is to the presence of this oil that the charac- teristic fragrant odour of " Russia " leather is due. oak apple galls 352 The World's Commercial Products Birch bark produces a soft light-coloured leather specially suitable for the " uppers " of boots and shoes. Chestnut Bark and Wood The bark of the common chestnut (Castanea vulgaris) contains practically as much tannin as oak bark, but is rarely used for tanning purposes. The green wood contains from three to four per cent, of tannin, and, like oak-wood, is employed as a source of extract in France, Italy, and Austro-Hungary, where it is available in large quantities. " Chestnut extract " contains from thirty to forty per cent, of tannin, and furnishes a firm, tolerably heavy, but rather grayish leather, which darkens somewhat when kept. It is imported principally from Italy and Austro- Hungary, and largely used in the United Kingdom as one of the ingredients of a mixture employed in tanning sole leather. Willow Barks These are obtained as bye-products in the cultivation of willows to be used for basket-making. They are employed more especially in Denmark, Belgium, Holland, and France for tanning leather intended for the manufacture of gloves and similar articles. The barks of Salix arenaria and Salix Russeliana are most sought after for this purpose. They contain from eight to twelve per cent, of tannin, and yield a peculiarly soft, pliable, light-coloured leather. Wattle Barks These products, also known as mimosa barks, are obtained from a series of acacias indigenous to the southern parts of Australia, and now largely cultivated in Natal. The best Australian species are the " broad- leaved " or " golden " wattle of South Australia (Acacia pycnantha), the bark of which may contain as much as forty to fifty per cent, of tannin ; the " golden " wattle of New South Wales (A. longifolia) yielding bark containing twenty to twenty-five per cent, of tannin, A. mollissima (A. decurrens) and A. dealbata with barks containing from thirty-six to thirty -nine per cent, of tannin. Little attention has been paid in Australia to the cultivation of wattles, but in Natal it is done on a large scale, the species A. mollissima and A. dealbata being those most commonly grown. The seed is sown in May at distances of about twelve inches in furrows six to eight feet apart. When the young plants are well established they are thinned out to about six feet apart. Very little care, except weeding, is then required by the plantation until the plants are about three feet high, when the lower branches should be pruned off so that a straight even trunk from which the bark can be easily detached may be grown. Bark may be collected from the time the trees are five years old but the richest is obtained when they are about ten to twelve years old. It is collected in September or December in Natal, being then richest in tannin. After stripping it is merely dried in the sun, and either cut into small 9 WATTLE CINCHONA.

It yields a firm, solid leather with a faint pink tint. DlVI-DlVI This material consists of the dried husks of the pods of a leguminous tree, Ccesalpinia coriara, indigenous to Central America and cultivated in South America, and, on a small scale, in Java, India, and Australia. In preparing it for the market the pods are split open, and the husks, which are similar to those of an ordinary pea pod, are spread out in the sun until they become hard, brown, and dry. Sumac This well-known and valuable tanning mate- rial consists of the dried leaves of Rhus coriara, a shrub cultivated in Sicily and growing wild in Austria and the Bal- kans. The plant thrives on sunny slopes of dry, stony, and barren soil ; it is usually grown from shoots and develops rapidly. Plucking of the leaves may be com- menced in the second, but preferably in the third year, and after fifteen years' growth the shrubs cease to yield leaves rich in tannin and should be replaced. The leaves are usually dried and ground several times in stone mills to produce a fine powder for export, seven per cent, of tannin. Photo by Sir Harry Johnston, K.C.M.G., K.C.B.

Canaigre or " Tanner V Dock" This product is one of the few roots used as a tanning material. The plant is a native of Mexico and the Southern parts of the United States, and is now exten- sively cultivated in those regions for the sake of its root. It is best grown from tubers, which should be planted out in the autumn, but may be also raised from seed. The roots are har- vested in the second year, and are cut into slices, which are dried in the sun or made into " canaigre extract." Good canaigre may contain from twenty-six to thirty of tannin, and yields a firm heavy leather of a bright orange colour. mangrove thicket Quebracho This material, which owes its name to its exceptional hardness, quebracho being a corrup- tion of the Spanish word for " axe-breaker," consists of the wood of a South American tree, Quebrachia (Loxopterygium) Lorentzii. The tree is a fairly large one, and is grown on an enormous scale in the Argentine Republic. The wood contains about twenty per cent, of tannin, and yields a firm but rather reddish leather. Myrabolans This, one of the most important Indian tanning materials, especially for export purposes^ consists of the unripe fruits of Terminalia chebula or T. belcrica, trees which are common in India, especially in Madras and the Central Provinces. The fruits are collected when full grown but still unripe, and are prepared for the market merely by drying in the sun. Gambier This material is also known as " white catechu." It is an extract prepared from the leaves and branches of a climbing plant, Uncaria gambier, which grows in the East Indies, especially in Malaysia. For the production of gambier, the trees are cropped almost bare of twigs four- times a year from the. time when they are three years old, so long as they bear well. The twigs with the leaves are chopped small and extracted by being boiled with water in copper pans until a syrupy liquor is formed. This is strained and allowed to flow into tubs, m which it sets to a brownish-white, semi-crystalline solid, which while still soft is cut into' approximately one-inch cubes. Mangrove Bark ''"/'The mangroves are an interesting group of trees, which inhabit the swampy foreshores of tropical countries where they form forests frequently of vast extent. The barks of all the mangroves appear to contain more or less tannin, but the species, which have so far been Tans and Dyes 355 exploited principally are Rhizophora mangle, Rhizophora mucrunata, and Bruguiera gymnorhiza, yielding barks containing from forty to fifty per cent: of tannin. The bark is merely stripped from the stems and branches, broken up into small pieces, and dried in the sun, preferably under cover. When dry it is packed into bales weighing about one cwt. The manufacture of mangrove tanning extract, and " cutch " is carried on on a considerable scale in Borneo and some other East Indian islands. - Mallet Bark This tanning material is derived from Eucalyptus occidentalis, and has been exported during the last few years on a large scale from South Australia. The bark, which is of medium thick- ness, is very hard and shows a cinnamon-brown colour ; it contains as a rule from thirty- five to forty-five and occasionally up to fifty per cent, of a readily soluble, yellow-brown tannin, which yields a firm, tough, light-brown leather. DYE-STUFFS Dye-stuffs of vegetable origin have become almost a negligible quantity in the world's commerce since the introduction of the so-called " aniline dyes," and what was at one time an industry of great importance to many agricultural countries has now sunk to comparatively small proportions. The vegetable dye-stuffs owe their characteristic colouring powers to the presence of small quantities of highly coloured substances (dyes) secreted by the plants. In general the " dyes " are not readily retained by fabrics unless the latter are first treated with a mordant. This consists in steeping the fabric in a solution of a weak salt of one of the metals iron, chromium, aluminium, or tin. The steeped fabric is then dried and treated with a current of steam whereby a fine layer of metallic oxide is formed all over it, i.e., the fabric is " mordanted." If it is now placed in an infusion of the dye-stuff, the " dye " forms a coloured insoluble compound with the " mordant," which is resistant to light and cannot be washed out. The coloured compound formed with each metallic oxide used as a mordant is different, and by this means a considerable range of tints may be obtained from each dye-stuff. Indigo This blue dye-stuff is obtained from a number of indigo-bearing plants (Indigofera tinctoria, I. arrecta, etc.) cultivated in India, Java, and Natal. It does not occur naturally in the plants but is formed by a process of fermentation. Fresh plants, collected at the flowering period (late summer in India and Java), are thrown into large vats con- taining water, and are thoroughly broken up by means of sticks wielded by natives. By this means the soluble matter contained in the plant is dissolved out. The watery extract is drawn off into a second vat, where it is thoroughly churned up so as to expose it as much as possible to the air. This " churning " is accomplished in India usually by natives, who wade about in the vat and beat the liquid with sticks, though the more enterprising planters have adopted the Javanese method of agitation with a current of steam or compressed air. The INDIGO 356 The World's Commercial Products Photo by Sir Hatry Johnston, K.C.M.G., K.C.B. By permission of Messrs. Hutchinson MANGROVE AND PANDANUS SWAMP liquid changes in colour from yellow to blue owing to the gradual production of the dye-stuff, which separates as a fine powder. When the action is complete the indigo is allowed to settle to the bottom, the water is run off and the dye-stuff collected, and while still wet and pasty made into little cubes." Indigo. as produced from plants is by no means a pure material. It contains even under the best conditions only eighty per cent, of pure indigo, or as it is technically called indigotin. The impurities present are water, mineral matter, indigo-red, and other substances. The purest natural indigo is that produced in Java. Indian indigos rank next in quality. Cutch This material, also known as " black catechu," as distinguished from " white catechu," or gambier was formerly prepared almost entirely in India from the heart- wood of Acacia catechu or Acacia suma, but recently several of the East Indian islands and the European Protectorates on"' the East Coast of Africa have commenced the preparation of a similar product from mangrove bark, which is known as " mangrove cutch." RED DYE-WOODS Logwood ■ * ..... . Th,is material is the heart- wood of Haematoxylon campeachianum, a spreading tree of moderate size_ seldom exceeding forty feet in height, native to the Bay of Campeachy, Honduras, etc. It was introduced into Jamaica in 1715, and is now largely grown there. The principal producing countries in order of importance are Mexico, Hayti, San Domingo, Cuba, Honduras, Jamaica, and the smaller islands, Guadaloupe, St. Lucia, and Grenada. Tans and Dyes 357 Brazil Wood, Lima Wood, (Peach Wood) Sappan Wood These materials, which all contain the same dye, " brazilin," are derived from a number of species of Caesalpinia ; thus Brazil wood is yielded by C. crista or C. brasiliensis, and is obtained principally from Brazil, Mexico, and Jamaica. Peach wood ! is derived from C. echinata in Mexico, and sappan wood from C. sappan, which is found in China, Japan, and the East Indies. The woods are applied in dyeing much in the same way as logwood, being as a rule first converted into extracts'. Camwood, Barwood, and Red Sanders (or Sandal) Wood These three red woods possess very similar tinctorial properties: Red sanders wood is derived from an Indian tree, Pterocarpus santalinus ; barwood from a West African tree, Baphia nitida, common in Sierra Leone ; and camwood is either identical with barwood or is'from a closely related tree. They are usually imported as coarse powders produced by rasping. YELLOW DYE-STUFFS Old Fustic This is obtained from Moms tinctoria, which occurs widely distributed in the East Indies, Central and Southern America, and the West Indies. The wood is hard, of a bright yellow colour, with a somewhat reddish tint, and comes into commerce in blocks weighing about one cwt. The best qualities come from Nicaragua, Cuba, and Jamaica, and medium kinds from Mexico and Venezuela. For dyeing purposes the wood is converted into extract by a process similar to that used with logwood. " Old fustic " contains two dyes, morin and maclnrin. It is principally used by the dyer for shading blacks and browns .as described under logwood. By permission of Messrs. W. Ransom & Sons, Hitch CUTTING PEPPERMINT 358 The World's Commercial Products Other well-known yellow dye-stuffs are Persian Berries, the unripe berries of a species of Rhamnus growing in Southern Europe, The Levant, Asia Minor, and Persia; Quercitron Bark, from a species of oak indigenous to the United States ; Weld ; Turmeric, which is largely grown in India; and Annatto, so widely cultivated in tropical countries. . Archil, Cudbear, and Litmus These three products are obtained from a number of different lichens imported from Ceylon and Mozambique, the most important being Roccella tinctoria and Lecanoria tinctoria, which possess the property of producing a violet-blue dye when exposed to the joint action of ammonia and air. For the preparation of archil the lichens are simply sprayed with a solution of ammonia and exposed to the air. When the dye is fully developed, the mass of lichens is extracted with water forming " archil liquor," or the latter may be evaporated to dryness forming ■ "cudbear." If the treatment of the lichens with ammonia is long- continued and lime is eventually added to the mass .before extraction with water, the purple dye "litmus" is ob- tained. This is usually sold mixed with chalk or powdered gypsum. Archil is used in wool and silk dyeing to produce purple colours. Litmus is used in chemistry for the de- tection of acids and alkalis; its natural purple tint is changed to vivid red by acids and to deep blue by alkalis. By permission of Messrs. John /akson & Co., West Croydon GATHERING MINT ESSENTIAL OILS The descriptive term " volatile " serves to differentiate these products from the " fixed " oils, which do not evaporate on exposure to air. The older name " essential " indicates that they are " essences," i.e., the constituents to which the plants containing them owe their peculiar properties, thus, the characteristic aroma and flavour of the well-known spice, cinna- mon, are due to the essential oil it contains, and this oil, possessing in a far higher degree the aroma and taste characteristic of cinnamon can be extracted from the spice, leaving a material devoid of odour and flavour. Volatile oils are usually prepared by a process of distillation in steam. For this purpose the materia] to be operated upon is ground, placed in a copper still, covered with water, and allowed to stand for some hours. The still is then..heated so that the water boils, producing steam, which carries away in a state of vapour the volatile oil contained in the plant, and this mixture of steam and oil vapour passes into the condenser attached to the still, where it forms water with a layer of oil floating on it. When the whole of the available oil has been procured in this way it is skimmed off the water and filtered. H H . 3D 359 360 The World's Commercial Products •*?f "K&O By permission of Messrs. Jjhn Jakson & Co., West Croydon CUTTING LAVENDER In some cases distill a- tion cannot be resorted to as the application of heat destroys the valu- able odorous constitu- ents. Thus, in preparing lemon and similar oils obtained from the rinds of Citrus fruits a process of expression is made use of for the prepara- tion of the best qualities, and only the poorest kinds are obtained by distillation. The fruit is cut into halves or quarters, and the adher- H ing acid pulp removed. ■ The portions of rind iMvk\X* !> are tnen eitner squeezed against a sponge held in the right hand of the operator or in the case of halves are pressed against it and rotated. In this way the small cells in which the essential oil is secreted are broken, and as the oil exudes it is absorbed by the sponge. When the latter becomes saturated the oil is squeezed out into a receptacle. In the West Indies, where lime oil is made on a large scale, the portions of rind are drawn across upright brass needles fixed in the bottom of a bowl, or the whole fruit is gently rolled over the points. The oil cells are thus pricked by the needles, and the oil flows out and accumulates at the bottom of the bowl. These "expression " and " pricking " processes do not remove the whole of the oil from the rind and the rest may be obtained by steam distillation, the distilled products being of inferior quality and selling at lower prices. When neither distillation nor "expression" processes are available, "enfleurage" methods are used, 'which consist in soaking the material in warm fat. From this the volatile oil is dissolved out -by pure spirits of wine. This process is used in the preparation of perfumes. The volatile oils are used as solvents, perfumes, flavouring agents, or drugs. It will be readily understood, therefore, that a considerable range of these products comes on the market ; attention can, therefore, only be directed to the few, which are of the first importance. Oil of Turpentine. The manufacture of this material has been described previously. It is produced chiefly in the United States, France, Russia, and Austria, and is employed principally as a solvent for resins in the preparation of oil varnishes, and as a vehicle for pigments in oil paints. Volatile Oils used in Perfumery "Otto of Roses." This extremely valuable oil has been in use for centuries in the East as a perfume. It is produced for export almost exclusively at the present day in Bulgaria from. the petals of Rosa damascena, and though considerable quantities are made in Persia, India, and elsewhere, these kinds do not come into European commerce. " Rose water" is made chiefly in the South of France by the distillation of the petals of the "cabbage rose" (Rosa centifolia with water ; it consists of a solution of a small quantity of " otto " in water. Essential Oils 361 Geranium Oil. This material is obtained by distilling the leaves of certain species of pelargonium cultivated in Spain, France, Algeria, and Reunion. Lemon Grass Oil. This is prepared in India from the grass of the same name (Anaropogon citratus). It has an intense lemon odour and is used for perfuming soaps. Lavender Oil. This is prepared by distillation from various lavender plants. In England Lavandula vera is cultivated largely in Surrey, Hertfordshire, Kent and Lincoln for this purpose. Oils obtained from Citrus species. These include the important oils procured from such well-known fruits as the orange, lemon, lime and bergamot, all produced by citrus trees. These oils are made chiefly in Sicily and Calabria (Southern Italy), though some of them are also obtained from the South of. France and the West Indies. They are, as already indicated, made by " expression " or " pricking " processes. The most important of them, as perfumery agents, are orange oil made from the rind of the "sweet orange, mandarin oil prepared from the peel of the mandarin orange, bergamot oil extracted from the bergamot fruit rind, and lime oil made chiefly in Montserrat and other West Indian islands from limes. Other oils of this species are Neroli, Ylang ylang, Patchouli. Opopanax, and Bay. Oils used as Flavouring Agents Lemon Oil. This is prepared principally in Sicily by the expression processes already described from the rind of the ordinary lemon. The chief centre of the trade is Messina. Essential Oil of Almonds is obtained from bitter almonds by grinding these with water and steam-distilling. The crude product is submitted to a chemical process of purification to get rid of the poisonous prussic acid it contains. By permission oj Messrs. W. Ransom & Sons, Hitchin GATHERING BELLADONNA 362 The World's Commercial Products Juniper Oil is prepared by steam- distilling the berries of the juniper tree (Juniperus communis), and is largely made in the United Kingdom, Germany, and Hungary. It is used to some extent in medicine, but principally as a flavouring agent for gin. Wormwood Oil is procured by the distillation of the wormwood herb (Artemisia absinthium) and is made chiefly in the United States, France, Spain, and Algeria. The oil is the flavouring ingredient of "absinthe" liqueur. A large number of other oils used as flavouring agents are obtained by the distillation of such well-known species as cinnamon, cassia, pimento (allspice), coriander, caraway, nut- meg, mace, cardamoms, spearmint, angelica, and cloves, and are applied much in the same way as the spices from which they are derived. Volatile Oils used as Drugs Camphor. This material is procured from the oil obtained by the distillation of the wood of the camphor tree, which grows in China and Japan, more especially in the island of Formosa. The tree has also been planted in Ceylon and Florida, and small quantities of camphor are now produced in both these localities. Eucalyptus Oils. The large trade in eucalyptus oils is of comparatively recent growth, and is due almost entirely to the vogue these. products have acquired as deodorants, antiseptics, and curative agents generally. They are obtained from various species of Eucalyptus, and are produced principally from indigenous trees in Australia and from trees grown in plantations in Algeria and the United States. Peppermint Oil. This oil is obtained by the distillation of various species of peppermint, such as Mentha piperita and Mentha arvensis. COCO-NUTS VEGETABLE OILS AND FATS Under* this title are included " fats " and "fixed oils." The distinction between "fats" and " fixed -oils " is merely one of degree, as " fats'" are reduced to an oily condition by heating. The "fixed oils" are entirely distinct from the "volatile" or "essential" oils. The latter differ in chemical, composition, and can be distilled without undergoing change, while the fixed oils are decomposed before they pass off as vapour. It will be convenient, to consider the oils under, the following headings :— (1) Drying Oils, (2) Semi-drying Oils, (3) Non-drying Oils, (4) Vegetable Fats or Tallows. In the class of drying oils linseed stands pre-eminent, and except in one or two applications no oil can be utilised in its place as a drying oil. The other oils in this group are used locally Vegetable Oils and Fats 363 or without regard to their drying properties. In the class of semi-drying. oils, cotton seed and the different rape oils are the most important. Among the . non-drying oils olive occupies the first place, but ground or earth-nut oil is an important article of commerce. Palm oil is perhaps the most useful of the vegetable fats, while the fatty products of the coco-nut palm provide a valuable asset to the countries where the tree flourishes. The methods of obtaining the oil from the seeds or fruits depend partly upon their size, hardness and. other qualities, also upon the consistency of the oil and the use for which it is intended. There are two general methods adopted, (1) by expression, when the material is crushed in a press and the oil squeezed out ; (2) by extraction, when the oil is dissolved out by suitable solvents. The different modes of pressing out the oil vary greatly from the primitive methods employed by natives of West Africa, India and elsewhere, to the modern extensive equipments of Europe and America, as described for cotton seed- oil (see p. 368). The machines employed for cleaning and preparing vary with the raw material, e.g., cotton seed and earth nut require to be decorticated, linseed and rape-seed have to be screened and cleaned, coco-nuts are treated in a breaker or disintegrator. Previous to pressing, large seeds or bulky material are first reduced in an edge-runner seed mill, consisting of two vertical stones revolving in a circular trough ; the final grinding, or, in the case of small seeds, the only grinding, is performed in seed crushers. The crushers contain one or more series of rollers, that are grooved for breaking up palm kernels and ground nut, or smooth for the comminution of linseed or copra. The material is delivered from the crushers as meal and passes at once, or after a preliminary heating, to the cake-moulding machine. The heat- ing is carried out in large cylinders known as "kettles," through which steam pipes are led for warming the meal ; besides rendering the oil more fluid, the heating helps to break up the oil-containing cells. The cold or heated seed-meal is measured out automatically into press cloths, that are generally made of closely- woven cotton cloth encased in close horse-hair cloth, and receives a preliminary squeeze to mould the material. The moulds or " cakes " are next transferred to the press. The presses are the most important item in the installation, and vary very considerably, but are all worked by hydraulic power. In the open- plate process the cakes enclosed in the cloth covering are packed between press-plates of a flat or grooved pattern and piled in the press. Twelve or more cakes are pressed in one of these machines, and the oil exudes from the meal Photo by W. H. Johnson, Esq., F.L.S. PALM OIL TREE 364 The World's Commercial Products ~ OLIVE TREES running down the sides, or is collected in grooves on the press - plates, whence it runs away to tanks situated below the press. Generally the cake is pressed a second and often a third time ; previous to each ex- pression the cakes are broken up in a cake- breaking machine or ground in the edge runner mill. As there is a danger of the cloths ripping, pan presses have been devised in which for the cloths are substituted circular iron boxes or pans. These are packed with meal, and between each there is inserted a circular plate with a conical edge. When subjected to pressure, the plates are forced down on the meal in the boxes, the oil escapes through holes in the inner lining of the boxes, and collects in a circular groove on the plates, whence it runs off to the tanks. These presses are closed and have the advantage that besides doing away with the cloths, the cakes are equally pressed throughout. Having described the general method of expression, the process of extraction may be shortly explained. In extraction the solvents used are principally petroleum ether and car- bon bisulphide. Petroleum ether is more dangerous on account of the greater inflammability of -the vapour, but carbon bisulphide produces noxious and poisonous fumes. The finely broken-up meal is put into a vessel that is closed down tightly and the ether or carbon bisulphide is introduced ; after passing over the meal and- taking up the oil, the solvent is transferred to a vessel heated by steam, and distilled off, leaving the oil below. The solvent is then condensed and returned to the storage cistern for further use. The oil, not being entirely free from solvent, is subjected to the action of direct steam or a water spray. The chief feature in:the extraction process is to arrange a plant that will work continuously until the oil is ready to be removed. The choice between expression and extraction depends greatly upon the use for which the oil or fat is required. For edible oils, such as olive, sesame, earth-nut, expression is necessary ; it is also advisable to express the oil when the cake is intended for feeding purposes. The danger of explosion is a deterrent to extraction, but. on the other hand, by extraction more oil can be obtained ; further, it is freer from mucilage and other impurities and the meal does not so readily become rancid. It is impossible within the space at disposal to enter into the methods of refining oils and f ats:. DRYING OILS Linseed Oil. Linseed is obtained from the flax plant (Linum usitatissimum), also extremely valuable on account of its fibre, which is manufactured into linen. Russia is the CAMPHOR TREE 365 366 The World's Commercial Products Photo by W. H. John only country from which both flax and linseed are produced on a commercial scale. In Europe the flax plant is grown chiefly for fibre. In other countries, notably in the United States, Argentine, Uruguay, and British India, which with Russia produce the bulk of the world's supply of linseed, the plant is grown almost exclusively for seed. The most interesting difference in variety exists between white- seeded and red-seeded forms, as recognised in India, although the statement is made that plants raised from white seed in certain soils produce — by reversion — red seed. The quality of oil from the white seed is generally reckoned superior. It is found advantageous to keep the seed for a few months before it is pressed for oil. Sifting, screening and grinding between rapidly- revolving rollers are neces- sary operations preliminary to pressing. Hot -pressing is usually practised, although the best grades of linseed oil, serving occasionally, as in Russia, for edible purposes or for mixing with paint, are cold pressed. The mucilage contained in the seed-coats known as " foots " has to be separated from the expressed oil, this being effected by forcing the oil through filter presses. There is no objection to the extraction of oil from the seed, and in America naphtha has been used for the purpose. The linseed oil is run into percolators, holding about 1,000 bushels of seed, where it is flooded with naphtha ; separation of the linseed oil and naphtha is produced in the ordinary way by distillation. The colour of linseed oil varies from a light to a brownish-yellow. The oil possesses an acrid taste and smell, soon becomes rancid on exposure to the air, and has the property of taking up oxygen from the air and drying to an elastic skin. This drying property is con- siderably increased by heating the oil with certain metallic salts, e.g., litharge, known as " driers," producing the so-called " boiled " linseed oil, although it is now known that a temperature of 65° C. is sufficient for the purpose. The principal uses of boiled linseed oil are for making paints and varnishes, in the preparation of printers' ink, and in the manufacture of linoleum. The following drying oils are also commercial : — - Candle-nut Oil derives its name from the custom of the natives in the South Sea Islands, who fix the seeds on bamboo and burn them as candles. The tree (Aleurites moluccana) is widely diffused throughout the Polynesian Islands and thence northwards to the Malay Peninsula. The oil dries about as rapidly as linseed and is suitable for varnishes, also for making soft soap. Tung or Wood Oil is a Chinese product obtained chiefly from the seeds of Aleurites cor data, a good-sized tree growing wild, and also planted along the roadsides in China and Japan. GOLD COAST. MILLER S PALM NUT-CRACKING MACHINE AT WORK Vegetable Oils and Fats 367 The cold-pressed oil of a pale yellow colour is known as " White " tung oil ; the hot-pressed, much darker, as " Black " tung oil. In China and Japan the oil is used as a preservative for coating timber, as a lubricant, and for illumination. Hemp Seed Oil is prepared from the fruits of Cannabis sativa, a plant of thenettle order. It is grown in Russia and Germany, in North America, in Egypt and other parts of Africa, also in Central Asia. The supply of seed for oil is principally European. The freshly prepared oil is greenish-yellow, with a peculiar taste and smell. Walnut Oil is obtained from the kernels of the common Walnut tree, Juglans regia. - The seeds give about forty to forty-five per cent., of oil. Walnut oil dries quicker than linseed, and is used as a medium for paints. Fresh cold-pressed oil is suitable for edible purposes. Maw or Poppy Oil is derived from the seeds of the Opium Poppy, Papaver somniferum, a herbaceous annual cultivated in India, Persia, Asia -Minor, and elsewhere for the sake of the opium extract. It is grown in the north of France and in Germany, where two varieties with black and white seeds are recognised ; the white yields the better oil, and the black is said to give a better return. Some of the oil pressed in the north of France is used for mixing with artists' paints and is sun- bleached by exposure in shallow troughs ; cold-pressed oil is also prepared as a table or cooking oil. The darker-coloured oil is used for burning or for conversion into soap. Safflower Oil is obtained from the seeds of Carthamus tinctorius, a plant belonging to the order Compositae, and is cultivated in India, Egypt, and China.

It is cultivated to a considerable extent in British India, where it was introduced from Abyssinia or Egypt. Sunflower Oil. The sunflower (Helianthus annuus) is an American plant, probably indigenous to Mexico, that has passed into universal cul- tivation for the sake of its flowers. As an economic plant it has received most attention in southern Russia.

To Americans must be given the credit of recognising the inherent capabilities of the oil, and this, combined with the very large quantity of cotton grown -in the United States, has given that country a long lead in the production of cotton seed oil and allied products. So much care has been bestowed: in America on the treatment of cotton seed for the oil, hulls, and cake that an account of . the processes furnishes a sgood instance of the intricate details of an oil mill. As the seed is ginned it is removed to* the mills where storage accommodation on a large scale 5 is*provided. In-the large factories as much as 200 tons of seed'are pressed for oil in a day. Nearly all the work at these mills is performed" mechanically. The seed having arrived at the mill is raised to the top -of the store by ■bucket elevators into a screw "conveyor" that distributes it wherever available. As required, it drops into another distributor that transfers therseed to the revolving " boll-screen," a cylinder perforated with holes sufficiently large to let the seed pass through, while bolls, fragments of stalk, and other large impurities are retained. From the boll-screen the seed passes to another revolving perforated screen, in which the smaller impurities, dust and sand, are separated. After this the cleaned seed is Photo by W. H.

The next process is the shelling of the seed, which is performed in the " hullers," composed of an outer cylinder and an inner drum, in both of which knives are set. The rapidly- revolv- ing knives break the shells and partly cut up the kernels or " meats." The mixture of hulls and meats is then conveyed to a revolving screen, through which the kernels pass while the hulls mostly remain behind, but a further separation is effected on an &m ItiM oscillating separator or '•shaker/' The hulls, owing to the persistent hairs, fall together in lumps and collect on top, while the meats fall through. The kernels or meats are crushed between heavy iron rollers and then carried .off to the heaters, steam- jacketed kettles, provided with stirrers to . keep the temperature even. From the kettles the meats are taken to:the "former," a machine that shapes the meats into cakes. The cakes, wrapped in hair cloths, are now packed into presses and. subjected to a pressure of from 3,000 to 4,000 lbs. to the square inch. The oil is squeezed, out and run off, while the cakes are pressed as hard as boards. The oil is pumped into a settling tank, where the impurities gradually subside to the bottom and theclear oil is drawn off above. "The settlings or " foots " are either passed through the press again or are' sold for soap manufacture. The oil-cake is, after the oil, the most important product obtained, and realises about one- fourth the price of oil. The value of oil-cake mixed with hulls as a food for fattening cattle has gradually been realised in the United States, but the bulk. of the oil-cake is still exported. Sesamum or Gingelly. The cultivation of Sesamum indicum, the plant yielding sesame oil, can be traced back to a remote antiquity. It is an erect growing herb somewhat similar to the Betony, with opposite leaves" and yellow or pinkish* flowers. • The "small flat seeds vary in colour from white to reddish-brown or black. ' The seeds contain about fifty per cent, of oil. India is the largest grower of Sesamum, or, as it is there called, " gingelly," and while some of the seed is expressed .in India,, the bulk is shipped to Marseilles. Gingelly is a bland oil, nearly colourless and without smell. . If carefully prepared it keeps sweet and is used in India for cooking purposes, for anointing, the body, for illumination, and in the manufacture of soap. Sesamum is also cultivated in Siam, Ghina, and Asia Minor, where the seeds are used to flavour bread -and cake. Palestine is said to produce the finest seed, which is exported from Jaffa. Marseilles is the great centre of the sesamum oil industry in Europe, but considerable shipments are made to Trieste and to German ports. In Europe the product of the first Photo ' Sir Harry Johnston, G.C.B., K.C.M.G. By permission of Messrs. Hutchinson & Co. RAFIA VENIFERA PALMS Vegetable Oils and Fats 371 expression forms a fine table oil that approaches most nearly tojpliye oil, for which it furnishes a substitute or adulterant. Rape Oils. It is convenient to include under this head the oils obtained from thevseeds of a number of plants belonging to the order Cruet ferae. In the narrowest acceptation of the word, the rape plant of Europe is Brassica campestns, var. rapus ; but no" distinction is made in this country between the product of this plant a.mlth.a.toi Brassica caiiipesiris which receives the name of colza oil in Germany, or Brassica rapa, to which the term " Rtibsen oil " is applied. The seeds of these three plants are very similar in shape and in colour, but as a rule colza seeds are larger and yield a greater proportion of oil." Rape is cultivated in France, Belgium; North Germany, Austria, Roumania, and Russia. In Europe a distinction is made between summer rape that is sown in spring and matures in five months, and winter rape that is sown in autumn and reaped the following summer ; winter rape is considered to yield better oil. The preparation of the seed for treatment consists in breaking down and crushing the seed, this being followed by pressing or extraction. The pressed cake is suitable for feeding cattle, the extracted cake is suitable for manure. Crude rape oil is dark-brown in colour, but is refined into a clear yellow oil that possesses a characteristic harsh, taste. Other semi-drying oils that find a commercial use are : — Kapok Oil, obtained from the seeds of Eriodendron anfractuosum, the Silk Cotton tree, cultivated for the " floss " that envelops the seeds. The oil, principally expressed from Java seed in Holland, approaches very closely in its properties to cotton seed , oil ; the better qualities serve for converting into butter substitutes, the poorer grades for soap-making. Maize Oil is manufactured chiefly in the United States of America from the germs of the Photo by W. H. Johnson, Esq., F.L.S.

These yield about thirty-five per cent, of a fairly thick, light yellow oil used for the same purposes as cotton seed oil. NON-DRYING OILS Olive Oil. The geographical distribution and characteristics of the olive tree (Olea europaea, have been described on p. 276. The olive flowers in North Africa, in Italy, and the South of Spain in March or April ; the fruits mature in about eight months, and the principal harvest falls in the months of December and January, or later. It is extremely impor- tant to gather the fruit when just ripe, as at this stage it contains the largest amount of oil, To obtain oil of the finest quality, not only should the olives be picked by hand, but the oil should be expressed within a day or two after picking. In addition to the oil contained in the fruit or pericarp, the seeds also contain a certain proportion of oil. The fruits are generally crushed entire in an edge-runner mill or in a roller mill, although the finest oil is obtained by crushing the flesh alone, when the fruit is reduced to a pulp or "marc." The marc is packed in circular baskets made of esparto grass, or in bags bound with horsehair bands. A press is filled with a number of these baskets or sacks separated by wooden or metal perforated plates, that equalise the pressure, while allowing the oil to pass through. The presses are of various kinds, some being hand-lever or screw presses, while the larger ones are hydraulic. In any case the first pressure is a light one, as thereby a pure, clean oil is obtained, known as " Virgin Oil." The product of a second expression is also suitable for edible purposes. The marc is then broken up and mixed with hot water before the next expression, and subsequently a residue of oil is sometimes extracted with such solvents as carbon bisulphide or sulphuric. ether. The expressed oil is sprayed to get rid of the mechanical impurities and to precipitate any matter in suspension, after which it is run into cisterns to allow of further separation and By permission of Messrs. Greenwood & Bailey, Ltd,. ANGLO-AMERICAN HYDRAULIC OIL PRESS Vegetable Oils and Fats 373 decantation. The fine sediment diffused through the oil falls to the bottom and the pure oil is drawn off from the top. It is still found necessary to filter the oil, and remove all traces of water before the oil is ready for consumption. Pure olive oil will keep for a long time, but when it is exposed to the air, if any water is present, fungi quickly develop and the oil turns rancid. The finest oil has a golden colour, tastes and smells slightly of the fruit, and is clear and limpid. Oil of a second quality is also designated " table oil." The oil subsequently obtained, known as "ordinary" or "common" oil, is thicker than the better quality oils, and has a yellowish or greenish tinge. Inferior grades are suitable for lubrication and for the manufacture of soap. The finest grades are supplied from the South of France and Italy. Spanish, Algerian, and Tunisian oils are of inferior quality. Earth or Ground Nut Oil. The leguminous plant {Arachis hypogaea), producing the fruit known by the names of earth nut, ground nut, monkey nut, and pindar, receives its name from the peculiar habit of ripening its fruit in the ground. There are two distinct types of the plant, the one with trailing stems that produces nuts from the flowers along the runners as well as near the root-stock, of which trie Mauritius is a common example. The other type of plant is more erect and the nuts arise almost entirely from the base. The varieties from Brazil, Pondicherry, West Africa, and Madagascar come under this type. The fruits consist of nar- row straw-coloured, wrinkled pods. The seeds are covered with a thin white, reddish or purple skin ; they have a slightly sweet nutty flavour and contain as much as thirty to fifty per cent, of oil. The cultivation of ground nuts is at present fairly world-wide. In South America they are grown in the Argentine, Brazil, and Costa Rica ; they are exten- sively cultivated in the United States and eaten when parched. On the West Coast of Africa the crop is very important in Gambia and Senegal, and on the East Coast nuts are exported from Madagascar, Mozambique, and German East Africa. Pondicherry was formerly the centre of the Indian trade, but now the ship- ments from Madras are on a larger scale. In Europe the expression of oil follows the usual course. The nuts, after being shelled, are Cleaned by brushing and By permission of Messrs. Greenwood & Batley, Ltd. broken between rollers; they self-contained belt-driven edge stones 374 The World's Commercial Products By permission of Messrs. Greenwood & Batley, Ltd. SEED HEATING KETTLE AND HYDRAULIC CAKE-MOULDING MACHINE are subjected to the blast of a fan to winnow out the skins and packed in cloths for the press. The oil is pressed out once or twice in the cold before, the meal is heated. The cold- pressed oil is almost colourless, has an agreeable taste and smell, and serves as an edible oil. The oil obtained by hot expression is of a yellow colour and is used in the manufacture of soap. The residue is a valu- able oil-cake that is used for cattle-feeding purposes. Tea Seed Oil is a non- drying oil prepared in China and Japan, where it is used for cooking and for illumination, being derived from the seeds of Camellia sasangua or Camellia oleifera. Castor Oil is obtained from the seeds of Ricinus communis, related to the Spurges, and most probably a native of North Africa, but now widely distributed throughout the tropics and the warmer temperate regions. It is cultivated in every continent, but the bulk of the world's supply is produced in India, about 70,000 tons of seed and nearly two million gallons of oil being annually available for export. In India a clear distinction is drawn between the commoner large-seeded variety and the small-seeded variety, the former sometimes grown as a perennial, the latter always treated as an annual. For medicine, as is generally known, cold-drawn oil is preferred. The fresh seeds, sifted and cleaned from dust and debris, are crushed between rollers and packed in gunny cloth, when they are lightly pressed to take the suitable brick form. The bricks, separated by iron plates, are placed in a screw or hydraulic press, and the oil is collected in pans. Water is added to the expressed oil, and the liquid is boiled until the water has evaporated ; by this means the albumen is solidified and the mucilage subsides to the bottom. The oil is then filtered and placed in cans for exportation. It. has a light straw colour. In addition to its value as a medicinal oil, castor oil was formerly used as an illuminant in India, but is now chiefly employed in the manufacture of Turkey-red oil, required in the dyeing and printing of cotton goods. ' The alizarine dyes, originally extracted from madder root, but now prepared synthetically, require to be dissolved in a neutral fat or oil, which besides dissolving the dye, must also penetrate the fabric. By treating castor oil with sulphuric acid a suitable solvent is found that receives the name of Turkey-red oil. Formerly olive oil was employed for the purpose, but it has been almost entirely replaced by castor oil. VEGETABLE FATS OR TALLOWS Palm Oil and Palm-kernel Oil. The well-known Oil Palm of the West Coast of Africa (Elaeis guin'eensis) furnishes two different oils— a bright yellow or red-coloured substance of a fatty consistence, palm oil, obtained from the fleshy outer covering of the fruits, and a white oil yielded by the kernels of the seed. Vegetable Oils and Fats 375 The Oil Palm has a wide geographical range in West Africa, from the Gulf of Guinea to the south of Fernando Po. It flourishes in the islands of Zanzibar and Pemba, and along the shores of the Central African lakes; also, supplies have lately been exported from the Philippine Islands. The palm reaches a height of thirty or more feet, and bears large "heads," each containing several hundred fruits. The fruits have a fleshy and fibrous outer layer of a bright orange-yellow or orange-red colour ; under this covering is a nut with' a very hard shell, which encloses the kernel. The preparation of palm oil is undertaken by the natives in the countries where the palm grows. To collect the fruits the native climbs up the palm and cuts off the fruit heads. The fruits, after a time, separate from the heads, are cleaned and put into iron or earthenware pots partially filled with water and boiled until they form an oily mass. This is transferred to a wooden trough, where it is left overnight to cool. At daybreak next morning, water having been added, men get into the trough and pound the oil out of the mass by treading it with their feet. The oil gradually rises to the surface and is skimmed off by women, who pass it through a sieve to remove the coarser impurities. It is then poured into a pot and boiled until the yellow-red oil rises to the surface (see p. 371). The oil is heated again to drive off any traces of water. Palm oil varies in colour ranging through all shades from orange-yellow in the " Lagos " varieties to a dirty red in the " Congo " oils. It has a somewhat sweetish taste and a charac- teristic odour. When fresh, it is a good edible fat and is extensively used as such by the natives, who greatly enjoy " palm oil chop," and to some extent by Europeans living in the country. Its chief commercial use in Europe is for the manufacture of soap and candles, and very large quantities are annually imported for this purpose. Another important application of the product is in the tin-plate industry, in which large quantities of " palm oil greases " are used for covering the surfaces of the iron plates to prevent oxida- tion previous to the tinning process. The oil ob- tained from the kernels of the nuts is known in the trade under the names of " Palm Nut Oil "and "Palm Kernel Oil." The nuts or "stones" freed from their oily fleshy outer layer are col- lected during the manufac- ture of palm oil, and the native worn en and children crack ■ — n iSKEKWOOD 4 8 AT LEV. LIMlTt-O.

The shells are thrown aside and the "palm kernels" collected either for the prepa- ration of the oil or for export to Europe. The bulk of the kernel oil used in Europe is prepared from imported kernels. The latter are screened to remove impurities and ground between rollers. The oil is expressed in hydraulic presses or extracted by the action of solvents, the expressed cake being used as a cattle food. Palm-kernel oil is white in colour, and in the fresh state has a pleasant smell and an agreeable nutty flavour. Coco-nut Oil. The Coco- nut Palm is the most useful and at the same time one of the most ornamental trees of the tropics. Ceylon is and has been for some time the prin- cipal producing country, and in addition to the very numerous small properties owned by natives, extensive groves have been planted by Europeans since 1841. In India the presidency of Madras is the chief centre of production, notably along the Malabar and Coromandel Coasts. The native state of Travancore, with which Cochin is associated, exports copra, coco-nut oil, coir, and nuts. The tree flourishes also in Malaya and the Philippines. Coco -nut trees yield the most valuable production of the South Sea Islands, all the export being in the form of copra. From East Africa, the Seychelles, and Mauritius, in addition to the local consumption there is an export of copra and oil. In the West Indies and Brazil the, palm is largely cultivated to furnish the demand for nuts that exists in the United States ; Trinidad and Jamaica both export coco-nuts. The roughly triangular fruit, about the size of a man's head, is covered with a thick fibrous husk which yields coir (see p. 324), and within, a hard shell encloses one seed. The oil is obtained from the kernel of the ripe nuts, and may be expressed locally, or the kernel is cut into portions and dried, when it receives the name of copra (see p. 369). There are a large number of other vegetable fats or tallows that regularly or occasionally arrive on European markets. It is only possible to mention a few of these. Carapa Fat is a thick and colourless fat, melting about 24° C, that is derived from the seeds of species of Carapa, belonging to the order Meliaceae. Jarapa guyanensis, a lofty tree, grows in Brazil, Guiana and on the West Coast of Africa ; Carapa moluccensis is found on the coasts of India, Ceylon, and the Moluccas. The kernels yield from fifty to sixty per cent, of fat which is expressed in France and the United Kingdom for use in soap-making. Mahua Butter is derived from the seeds of Bassia latifolia, the " Mahua " tree of India, of the order Sapotaceae, grown widely in Central India. In Southern India Bassia longifolia takes its place. The seeds contain about fifty per cent, of fat. By permission of Messrs. Greenwood & Batley, Ltd. ANGLO-AMERICAN SEED-CRUSHING ROLLS Vegetable Oils and Fats 377 Phulwara Butter is the produce of an allied tree (Bassia butyracea), known as the Indian "Butter" tree. Shea Butter is obtained from the seeds of Butyrospermum Par kit, a large tree, allied to the Bassias, widely diffused through northern tropical Africa. The seeds yield about fifty per cent, of fat, having at ordinary temperatures a buttery consistency ; it'is greyish in colour,, and when fresh has a pleasant taste and smell. The seeds imported into Europe pass to candle and soap factories. SPICES AND CONDIMENTS A large number of vegetable products, although of themselves of little or no nutritive value, have been used by man from the earliest times to render ordinary articles of food more palatable. Such substances are known as spices and condiments, and, in addition to merely improving the flavour of the food, in a large number of cases they act as digestives, since, in coming into contact with the membranes of the digestive tract, they cause an increased secretion of the digestive fluids. ' Many condiments, such as salt, vinegar, and artificial compounds do not come within the 'scope of this article, which deals with the more important of the spices and condiments derived from plants. Vanilla This well-known spice consists of the cured pods of one or more species of Vanilla, a genus of Orchidaceous plants, native to South America. The bulk of the vanilla of commerce is the product of Vanilla plant folia, a climbing plant indigenous to Mexico, but now cultivated in several parts of the tropics, notably in Java, Seychelles, Mauritius, and Ceylon. The methods of culture and preparation vary somewhat in different parts of the world, and the system adopted in Seychelles will be described. Vanilla was introduced into these islands in 1866, probably from Reunion. The vines are trained over small trees, or on hardwood stakes connected at the top by crosspieces ; the most satisfactory method is to allow each plant a separate tree over which to climb. The supporting trees are planted about nine feet apart, those already standing on the estate being utilised as far as possible. The vanilla cuttings are planted at the foot of the trees, covered with a mulch of dead leaves and grass, and the free ends tied to the tree by strips of the leaf of the Screw Pine (Pandanus utilis). Their rapid growth soon enables the shoots to be trained through the forks of the branches to which they attach themselves by tendrils. At the end of eighteen months the plants are pruned in order to induce the formation of flowers on easily accessible branches. The checked branches, generally from four to six feet long, now hang down to within about a foot from the ground, and it is upon these branches that the flowers are chiefly formed. The fully developed pods are only formed after the flowers have been fertilised, and, in a state of nature, this very seldom happens pimento or allspice 378 The World's Commercial Products A VANILLA VINE owing to the peculiar form of the stigma rendering the transference of pollen a matter of great difficulty. On an estate, therefore, " pollination " is effected artificially by hand, the pollen being placed upon the stigma by means of a finely - pointed piece of bamboo. The flowers are not all pollinated, the actual number depending upon the size and condition of the vine. Generally speaking, about thirty pods per vine are allowed to mature, the flowers on the lower part and sides of the cluster being chosen, since they yield the best and most shapely pods. The pods reach their full size in about six weeks, and, when ripe turn slightly yellow. They are then picked from the vine, great care being exercised to avoid splitting or cracking the pods which would at once rank them as inferior grades. Before the pods are ready for the market as vanilla they are subjected to a curing process, during which their characteristic odour is developed. The aroma and flavour are chiefly due to the presence of a substance known as vanillin contained in a fluid which gradually permeates the whole fruit ; it further slowly accumulates as crystals on the outside of the cured pods. The pods are roughly divided into four classes according to size, and then, in batches of about four hundred, placed in a basket and plunged into hot water at about 190° F. for ten seconds. The process is repeated twice for slightly longer periods at intervals of half- a-minute, and, after the third dip, the pods are placed in boxes, lined with a blanket, to sweat ; the pods themselves are also covered with a blanket to retain the heat. By the next morning the pods have assumed a chocolate-brown colour, and are then placed on shelves in drying rooms maintained at a temperature of about 1 10° F. ; the slower the drying process the more perfect the curing. Well-cured pods should be much wrinkled, bending easily. When the curing is complete the pods are dried with pieces of flannel, and temporarily stored in boxes with tightly-fitting lids. They are then carefully sorted into different grades and finally bound up into bundles of about fifty each, and packed, with great care, for export. The cultivation of vanilla affords a good instance of a planting industry threatened by the advances of modern chemistry. Within recent years considerable quantities of " vanillin," or artificial vanilla, have been manufactured on the Continent, chiefly in Germany and France. Vanillin was discovered as early as. 1858, but its preparation upon a commercial scale did not rneetr jwith success until 1890, when the product was obtained from eugenol, the substance to which ." oil . of . cloves. " owes its characteristic odour. More recently vanillin has been prepared, from, sugar byr an electroLypic process. . • ■ ;.. .- v. . ,:......... . • -.. PEPPER; , Under the term " pepper " or "peppers " are included more than one spice, but the most important are the black and white- pepper so largely used as a condiment. ." Black pepper " consists 'of' the dried, unripe fruits of Piper nigrum, a perennial climbing shrub found native in the 'forests of Travancore -and Malabar in Southern India, and largely cultivated in Java, Sumatra, Borneo, the Philippines, Siam, and also in the West Indies. Spices and Condiments 379 A large, proportion of the supplies come from the Malabar Coast. In planting pepper in this district, the jungle is cleared and planted with seeds of rice, cotton, castor oil, and other " catch " crops, and also with the seeds of Erythrina indica, the latter being a large tree sub- sequently used as a standard upon which the pepper vines are trained, and also as a shade tree. The catch crops are regularly harvested, but the Erythrina is left to grow for two years, when the poles are cut and planted out in regular rows. The pepper cuttings are then planted at the foot of the poles, which quickly take root and afford support and shade to the vines. Other trees used for a similar purpose are the Mango {Mangifera indica) and-the Jak (Artocarpus integri folia). In two or three years the pepper bears spikes of red berries which are carefully picked by hand, the men using light ladders to reach them. The berries are gathered before they are fully ripe, and after being separated from the stalk by rubbing with the hands or feet are spread on drying grounds (barbecues), where they become black and shrivelled. The product is then ready for the market. " White pepper " has exactly the same origin as black pepper, but the berries are allowed to become nearly ripe. They are then soaked in water, and the outer skin of the fruits removed by rubbing with the hands. i " Long pepper " consists of the unripe fruiting spike of Piper longum dried in the sun. The plant is a native of the Malay Archipelago, but is also cultivated in many parts of India. " Tailed peppers " or cubebs have been dealt with in the article on " Drugs." " Cayenne Pepper " : see " Chillies " in this article. Cloves Cloves are the unopened flower-buds of Eugenia caryophyllata, an evergreen tree reaching a height of twenty feet or more, and regarded by botanists as a native of the Moluccas. Supplies of the spice are chiefly obtained from Zanzibar and Pemba, but the best qualities are said to come from Penang and Amboyna. The clove is by far the most important agricultural product of Zanzibar and Pemba, where the trees flourish to perfection. They are raised from seed, the young seedlings being very carefully shaded and watered. When about six inches high the plants are gradually exposed to the full force of the sun and then planted out in regular rows at distances of about twenty-five feet. The clove tree begins to bear from the fifth to the seventh year. The picking of the young unopened flower-buds commences in August and lasts until about November, each tree being picked, on an average, three times a season. The stalks and buds are picked off by hand together, and thrown on to grass mats spread out on the ground. The curing process which follows is very simple ; the cloves are picked from the stalks (which are subse- quently used as a source of inferior qualities of clove oil), and spread out in the sun to dry, care being taken to place them under cover during the night to avoid the dews. The curing occupies about a week. pepper vines i &L* v ' -**v. w "■:. ft** ¥ >v:"' ■ . ■ <> • 380 The World's Commercial Products CEYLON. DRYING CARDAMOMS Zanzibar cloves are larger than the Pemba variety, and, unlike the latter, are not black but red in colour, being known in the trade as " Zanzibar red-heads." Cloves owe their valuable properties to the presence of a considerable quantity of the volatile oil, oil of cloves. » Nutmegs and Mace This valuable spice' consists of the dried kernels of the seeds oi-Myristica fragrans, a tree about twenty-five feet" high, in general habit somewhat resembling an orange tree. The flowers are of separate sexes, the trees being either male or female ; .the nutmegs are, of course, obtained only from the latter. The round or oval fruits, which closely resemble a small peach in size and shape, are at first green, but become yellow on ripening. The thick, fleshy outer covering gradually becomes dry and leathery, and separates into two valves from the apex exposing the scarlet " mace," a reticulate membrane covering a thin brown skin which encloses the true kernel or nutmeg. The latter, when cut across, is found to be yellowish, with dark-brown mottled veins due to the' infolding of the seed coat. Myristica fragrans is a native of the Malay Archipelago, and 'is abundant in the Banda Islands, whence, for a long' time, supplies were chiefly obtained. The industry, for many years, was a monopoly of the Dutch Government, but in addition to the plantations of Banda, Sumatra, and Java, numerous varieties are now cultivated in Penang, Singapore, Ceylon, and the West- Indies, especially 4rr "Grenada. The plants are raised from seed, and nine years. must elapse before the first crop can be gathered. It is only when they are six or seven years old that the female plants can be distinguished from the males, and of the latter only a few are allowed to remain for fertilisation purposes, the remainder being cut down to allow Spices and Condiments 381 of the planting of new seeds. Since this method is very uncertain and involves a great loss of time, the modern practice is to graft a branch of a female tree on to all plants when two years old before the sexes can be distinguished. When ripe, the fruits are gathered by hand and the outer part discarded. The mace is carefully removed to avoid breakage, flattened out, and dried in the sun, when it loses its brilliant scarlet colour. It is well known as a valuable spice. The seeds are dried in ovens or in the sun for several weeks until the- kernels rattle in the thin outer seed coat. The latter is then broken and the kernels or nutmegs cleaned and packed for export. The " mild " or " long " nutmeg is much inferior to the true nutmeg • arid- is derived from a variety of M. fragrans, which is sometimes regarded as a distinct species, M. fatua. The Papua nutmeg is the kernel of M. argentea. There are several other so-called nutmegs which are of little or no use as a spice, the more important being the Calabash or Jamaica nutmeg (Monodora Myristica) ; the Brazilian nutmeg (Cryptocarya moschata) ; and the Californian nutmeg (Torreya Myristica), Ginger Ginger is prepared from the dried rhizomes of Zingiber officinale', a plant with :a somewhat reed-like habit found truly wild only in Asia, but now cultivated in many parts' of the tropics, By permission of Messrs. Peek Bros. & Winch, Ltd. CEYLON. PREPARING CINNAMON 382 The World's Commercial Products A NUTMEG TREE' IN- JAMAICA notably in South America, the West Indies, ' West Africa, and the warmer parts of Queensland. The finest qualities of the spice are probably obtained from China,, and the West Indian product is also justly famous for its quality. The methods of culti- vation and preparation are essentially the same in all parts of the world. In planting out, rhizomes of mature plants are cut up into short lengths, each pos- sessing at least one " bud," which are planted about two feet apart. The harvest commences when the leaves begin to wither, which usually takes place after about ten months. The rhizomes are then very carefully dug up, and the fibrous roots and adherent earth removed. From this point the treatment varies according to whether dried . or preserved ginger is required. Dried ginger is of two kinds, peeled and unpeeled, the latter being merely the cleaned rhizomes dried in the sun. In the preparation of the peeled variety, the cleaned rhizomes are thrown into water and then peeled with a narrow- bladed knife, care being taken to remove only the thinnest possible layer, since the essential oil and resin, to which ginger owes its pungent flavour, occur just beneath the skin or epidermis. After peeling, the ginger is again soaked in clean water to which chemicals are often added to improve the colour of the " roots." The ginger is then dried in the sun on a paved or cemented barbecue, the process occupying from six to eight days, when the product is ready for export. Preserved ginger is prepared chiefly in China. The washed rhizomes are put into boiling water, and, after being peeled, placed in earthenware vessels and a strong boiling solution of sugar poured over them. The syrup is drained off after twenty-four hours, and the process repeated for two days. The ginger is then taken out of the syrup and is ready for export, appearing on the market either dry or packed in jars. Allspice, Pimento Pimento or allspice consists of the dried unripe fruits of Pimenta officinalis, a beautiful tree about thirty feet high with a straight trunk much branched above, bearing abundance of dense, evergreen foliage. The plant is a native of the West Indies, Mexico, and South America, but the chief supplies of the spice are obtained from Jamaica, whence the name " Jamaica pepper " is derived. The fruits are spherical berries, which when ripe are smooth, shining, and of a black or dark purple colour. They are gathered when of full size, but while still green. A boy climbs into the tree, and, bending down the branches, snaps off the smaller ends leaving the fruits which fall to the ground to be gathered by women and children. The berries are removed by hand, and carefully cured on large paved barbecues, the process occupying from six to ten days. The spice consist of small, spherical, wrinkled fruits about the size Spices and Condiments 383 of a pea, crowned with the remains of the calyx and style of the flowers. It possesses a very fragrant odour, and the name " Allspice " is derived from the fact that* the odour is regarded as resembling a combination of the fragrance of cinnamon, cloves, and nutmegs. Cinnamon and Cassia This spice is the bark of young shoots of Cinnamonum zeylanicum, a small evergreen tree indigenous to Ceylon and related to,; the camphor- tree, C. Camphor a. The. plant is also said to be a native of the Malabar Coast,1 and -has been introduced into Java, Reunion, the Cape Verde Islands, Brazil, the West Indies, and Uganda. Cinnamon was -the most famous of the early exports of Ceylon, and, until 1833, was a Government monopoly. With the abolition of the monopoly the cultivation greatly increased, especially in the light, sandy soils near the south-east coasts. .At the present day about 40,000 acres are under cinnamon in Ceylon. '- • Left to itself, Cinnamonum zeylanicum would be a small tree, but in the plantations it is kept coppiced in order to induce the formation of : long willOwy shoots from 'which the bark may be obtained. The r * shoots are cut and trimmed with a knife, the small waste pieces resulting from the operation being known in the trade as " cinnamon chips." The bark is then slit longitudinally and re- moved in strips with a special knife. The strips are collected into bundles, which are piled in heaps to undergo a slight fermenta- tion, a process which facili- tates the next operation of removing the epidermis by scraping with a curved knife. The bark dries and contracts into the well-known "quills," which are bound into bundles. Cinnamon peelers are a separate caste among the Sinhalese. The finest qualities of cinnamon are light yellowish- brown in colour, smooth, very thin, and, to a certain extent, pliable. Inferior grades are darker and thicker, with inferior fragrance. As is the case in most spices, the fragrance is due to the pres- ence in the bark of a volatile oil (" oil of cinnamon ") ; similar but inferior oils are obtained by distillation of nutmegs 384 The World's Commercial Products the leaves and roots. " Cassia " of the ancients was probably derived from the bark of several species of Cinnamonum, but the cassia of modern commerce (" Chinese Cassia ") is the fragrant bark of C. Cassia (C. aromaticum), a plant growing abundantly in southern China, whence there is a large export. The bark is often used to adulterate true cinnamon. Saigon Cassia is regarded as superior to Chinese Cassia ; it is grown in French Indo-China. Cardamoms This spice, better known in India and the East than in Europe, consists of the seeds of two species of Elettaria, viz., E. Cardamonum, the Malabar cardamom, found in the moist forests of north Canara, Coorg, and Wynaad ; and E. major, the Ceylon cardamom, a variety of the first species. The plants have a reed-like habit and bear long, loose racemes of flowers succeeded by triangular capsules containing the seeds. The fruits, which vary from half-an-inch to two inches in length, are collected from wild plants and also from plantations, the latter being generally laid out in partially cleared forests in which the wild plants are known to occur. When about three years old the plants begin to bear. The capsules do not all ripen at the same time, and the harvest lasts for nearly three months. The capsules are gathered before they are ripe and then cured in the sun, after which the stalks and remains of the flowers are carefully removed by means of scissors. Cardamoms are exported in the capsules in order to prevent adulteration of the seeds. The seeds are small and irregularly angular, possessing a very delicate aroma. They were well known to the ancients, and are very largely used throughout the East as a condiment. They are employed to a small extent in Europe for flavouring sweetmeats. At the present time great interest is being taken in cardamom cultivation in Ceylon, and special efforts are being made to push the sale of the product in the markets of Australia and Europe. Several other varieties of Cardamom enter into the commerce of the East, but they are all inferior to those described above. > Chillies and Cayenne Pepper Chillies are the dried fruits of Capsicum minimum and C. frutescens, small erect shrubs with spreading branches. The former is the more important, and, although a native of India, it is now found in all parts of the tropics, being largely cultivated in East and Central Africa and in South America. The pointed, oblong fruits are about three-quarters of an inch in length, and of a bright scarlet colour, changing to orange-red on drying. They are used for pickling, and, when ground in a mill form " cayenne pepper." The pungent principle of the condiment exists chiefly in the partition dividing the fruit into two chambers. Mustard This popular condiment should consist, properly speaking, of the flour obtained by grinding the seeds of Brassica nigra (Black Mustard) and B. alba (White Mustard), plants belonging to the Crucifer family, and widely distributed in Europe and certain districts of North Africa and Asia. Much adulteration is practised, however, with starch, turmeric, and other sub- stances. The plants mentioned are largely cultivated in several parts of the Continent, and in the eastern counties of England. The finest mustard is obtained from the small reddish- brown seeds of B. nigra, the larger yellow seeds of B. alba yielding inferior qualities. When ripe the seeds are threshed from the plants, ground between rollers and pounded, the resulting flour being sifted into various grades. Brassica juncea, largely cultivated in India, is the source of " Indian" or " Brown" mustard.
