Under these circumstances, the author believes he will be performing a useful service, in bringing the question of the economical relations of American slavery, once more, prominently before the public. It is time that the true character of the negro race, as compared with the white, in productive industry, should be determined. If the negro, as a voluntary laborer, is the equal of the white man, as the abolitionists contend, then, set him to work in tropical cultivation, and he can accomplish something for his race; but if he is incapable of competing with the white man, except in compulsory labor,--as slaveholders most sincerely believe the history of the race fully demonstrates--then let the truth be understood by the world, and all efforts for his elevation be directed to the accomplishment of the separation of the races. Because, until the colored men, who are now free, shall afford the evidence that freedom is best for the race, those held in slavery cannot escape from their condition of servitude. Some new and important facts in relation to the results of West India emancipation are presented, which show, beyond question, that the advancing productiveness, claimed for these islands, is not due to any improvement in the industrial habits of the negroes, but is the result, wholly, of the introduction of immigrant labor from abroad. No advancement, of any consequence, has been made where immigrants have not been largely imported; and in Jamaica, which has received but few, there is a large decline in production from what existed during even the first years of freedom. The present edition embraces a considerable amount of new matter, having a bearing on the condition of the cotton question, and a few other points of public interest. Several new Statistical Tables have been added to the appendix, that are necessary to the illustration of the topics discussed; and some historical matter also, in illustration of the early history of slavery in the United States.
