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."
