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.
