We cannot agree with M. Villemain, who, in his report from the Academy, decreeing a prize of three thousand francs to M. Cochin for this work, speaks of it as inspired with 'eloquent zeal' and 'ardor.' It is very far from what it might have been as a _literary_ production; and to one not interested in the facts and subject, is even--with the exception of its excellent Introduction--dry. The author is decidedly an economist, but he is _not_ 'an apostle,' as his eulogist claims, unless it be in the sense in which any great collector and publisher of truths may be termed such. But on its true basis the work is indeed a great one, fully deserving the publisher's advertisement words, 'opportune and important.' The volume before us is a complete history, in a minor degree, of Slavery, and to a very full degree of Emancipation in the English and French colonies, with some account of the same in those belonging to Holland, Denmark, and Sweden. Having made for many years a specialty of the subject, and having had placed at his disposal the published and unpublished papers and records of every ministry of Europe, as, for instance, of the English Board of Trade, M. Cochin has accumulated a mass of extremely valuable material--all of which is presented in a very clear, perfectly well arranged form--and which we need not say should be read by every one in public, since there is certainly no intelligent American at the present day on whom the necessity of acquiring full information on this subject is not almost a solemn duty. Next after crushing rebellion, the great task of the Federal Government should be to organize labor and adopt a vigorous _central_ and _industrial_ policy. To do this, the relations of free and of slave labor to circumstances should be extensively studied. As in the case of all wars involving an institution, the question between the North and the South at the present day is simply one between ignorance and knowledge--knowledge such as books like this are eminently adapted to disseminate. Passing by religious and philosophic argument, neither of which has been of much practical avail in this country, since we see the Church of the South quite as zealous in upholding slavery on Biblical grounds as that of the North is in opposing it, we come to Cochin's first real argument--that political economy affirms the superiority of free over forced labor. Policy and charity unite in this--'charity detests slavery because it oppresses; policy, more elevated, condemns it _because it corrupts the inferior race_.'
