"If (he said) you were to place before any manufacturer specimens of all the substances which could be employed in his particular manufacture, and if you could tell him from whence each could be procured, its cost, the quantities in which he might obtain it, and its physical and chemical properties, he would soon be able to select for himself the one best suited for his purposes. This, however, has never happened in relation to any one art; in every case manufacturers have had to make the best of the materials which chance or accident has brought before them. It is strange and startling, but nevertheless perfectly true, that even at the present time there are many excellent and abundant productions of nature with which not only our manufacturers, but, in some instances, even our men of science, are wholly unacquainted. There is not a single book published which gives even tolerably complete information on any one of the different classes of vegetable raw produce at present under our consideration. The truth of these remarks will be felt strongly by any one who takes the trouble to examine any of these great divisions of raw materials. He will obtain tolerably complete information respecting most of those substances which are known in trade and commerce; but of the greater number of those not known to the broker, he will learn little or nothing. Men of science, for the most part, look down upon such knowledge. The practical uses of any substances, the wants and difficulties of the manufacturer, are regarded as mere trade questions, vulgar and low—simple questions of money. On the other hand, mere men of business do not feel the want of such knowledge, because, in the first place, they are ignorant of its existence, and secondly, because they do not see how it could aid them or their business; and if it should happen that an enterprising manufacturer desires to learn something of the cultivation and production of the raw material with which he works, he generally finds it quite impossible to obtain any really sound and useful information. In such cases, if he is a man of energy and of capital, he often is at the cost of sending out a perfectly qualified person to some distant part of the globe, to learn for him those practical details which he desires to know. This is no uncommon thing; and many cases might be stated, showing the great advantages which have arisen to those who have thus gained a march upon their neighbours."
The Society of Arts, appreciating the importance of from time to time encouraging the introduction of new and improved products from our Indian and Colonial Possessions, has offered many gold medals as premiums for a great variety of staples from abroad.
The Great Exhibition of the Industry of all Nations brought together an immense variety of productions from tropical regions, of which the English public were comparatively ignorant. Attracting public attention, as these necessarily did, information on the best modes of cultivating and manufacturing them will be peculiarly valuable to the colonists, and is as eagerly sought after by many brokers, merchants and manufacturers at home.
In consequence of the recent liberal policy of Great Britain, the competition of foreign countries, the want of cheap and abundant labor, and other causes, those chief staples, Sugar and Coffee, which for a series of years formed the principal and almost exclusive articles of production in our colonies, and which had met with a ready and remunerative sale in the British markets, have either fallen off to an alarming extent, or become so reduced in price as scarcely to repay the cost of cultivation. The partial abandonment of the cultivation of these staples in our colonies has had the effect of crippling the agricultural and commercial enterprise of several of our most valuable foreign possessions, and throwing out of employment a number of persons: it behoves us, therefore, to direct attention to some of the many minor articles in demand;—to those indigenous or exotic products of the soil in tropical regions, which, being inexpensive in cultivation and manufacture, might be undertaken with a moderate outlay of labor and capital, and the certainty of a ready and remunerative sale in the European markets; and could moreover be attended to without neglecting or at all interfering with the cultivation of the leading staples.
It is evident that the export wealth of tropical regions must be chiefly agricultural, the soil and climate being peculiarly fitted for the culture of fruits, trees and plants yielding oils, gums, starch, spices, and other valuable products, which no art can raise cheaply in more temperate latitudes. The large and continued emigration of farmers and other enterprising persons from Britain and the Continent to Natal, the Cape Colony, Northern Australia, Ceylon, the East India Company's Possessions and the Straits Settlements, Brazil, New Granada, and the Central American Republics, Texas, the Southern States of North America, and other tropical and sub-tropical countries, renders information as to the agriculture and productions of those regions highly desirable. Even to the settlers in our West Indian possessions, most of whom have too long pursued the old beaten track of culture and manufacture, comparatively regardless of modern improvements and the results of chemical, scientific, and practical investigation, recent information on all these subjects, and a comparison of the practices of different countries, cannot fail to be useful.
There is much valuable information to be met with in detached papers and essays in the scientific periodicals of the day, and in colonial and other publications; such as the Transactions and Journals of the different agricultural and horticultural societies of the East and West Indies, the United States, Australia, &c., but none readily accessible for easy reference, and which the new settler, proceeding out to try his fortune in those fair and productive regions of the globe, can turn to as a hand book. I have had much experience in Tropical Agriculture, and for many years my attention has been mainly directed to this important subject, for which purpose I have kept up a large and extended correspondence with numerous agricultural, scientific and other societies abroad; with experienced practical men, and have also received the leading journals of all the tropical Colonies.
No one person could be expected to be thoroughly familiar with all the different modes of culture and preparation of every one of the numerous products to be described in this volume; but where my own agricultural experience (of several years in the West Indies and South America) was at fault, I have availed myself of the practical knowledge of those of my colonial friends and correspondents best informed on the subject, and am particularly fortunate in having many valuable essays on Tropical Agriculture scattered through the different volumes of my "Colonial Magazine."
The discussion of the best modes of culture, properties, manufacture, consumption, uses, and value of the commercial products of the vegetable kingdom cannot be without its value, and the attention of merchants and planters may be usefully directed to various articles, which will be profitable both in an agricultural and commercial point of view; many of which are already sources of wealth to other countries.
The introduction of new objects of industry into the colonial dependencies of the British Empire, is no longer considered a mere subject of speculation, but one well worthy the attention of the eye of science; and the fostering hand of care is beginning to be held out to productions of nature and art, which, if not all equally necessary to the welfare of man, yet certainly merit the attention of the cultivator and capitalist, and have great claims on the scientific observer, and on those interested in raising the manufactures of our country to a higher standard.
Few who have not investigated this subject are aware of the immense number of countries lying in the equatorial and tropical ranges of the torrid zone, many of which, from the value and importance of their indigenous productions, have already attracted considerable notice, and to which still more attention will be directed by European nations as the value of their various products becomes more extensively known.
