"Several of the great proprieters were induced by these circumstances to give liberty to a certain number of their slaves annually, and by encouraging marriages between them and the Indians of the country, to propagate a race of free labourers, who might be employed when a supply of Slaves was no longer to be obtained. "This plan proved so eminently successful that on some of the largest estates there was not a single slave in the year 1808. "The policy of the measure became still more apparent on the breaking out of the revolution in 1810. "The planters who had not adopted the system of gradual emancipation before that period saw themselves abandoned, and were forced, in many instances, to give up working their estates, as their slaves took advantage of the approach of the insurgents to join them en masse; while those who had provided themselves with a mixed cast of free labourers, retained even during the worst times, a sufficient number of men to enable them to continue to cultivate their lands, although upon a smaller scale." The same work for September 1829, speaking of free and slave labour, remarks. "The controversy is fast tending to its termination. The march of events will scarcely leave room much longer, either for misrepresentation or misapprehension. The facilities already given in Bengal by Lord W. Bentinck, to the investment of British capital and the development of British skill in the cultivation of the soil; the almost certainty that those fiscal regulations which have hitherto depressed the growth of sugar in Bengal, and prevented the large increase of its imports into this country, will soon be repealed; the prospect of an early removal of the other restrictions which still fetter the commerce of our Eastern possessions: the rapidly increasing population and prosperity of Haiti; the official statements of Mr. Ward, as to the profitable culture of sugar by free labour in Mexico; and the rapid extension of the manufacture of beet root sugar in France; a prelude as we conceive, to its introduction into this country, and especially into Ireland; all these circumstances combined, afford a promise which can scarcely fail of seeing a death blow inflicted on the culture of sugar by slave-labour, which all the misrepresentations of all the slave holders in the world, with all their clamourous partisans in this country cannot avert, or even long retard." Since their views have been directed to the subject, your committee are fully satisfied that its further investigation will be highly important; and that at no very distant period, _the results of very interesting experiments nearer home may be obtained_. Respectfully Submitted, B. LUNDY, Chairman.[6] _Baltimore, December 1, 1829._ AN ACT TO PROHIBIT THE CARRYING ON THE SLAVE-TRADE, FROM THE UNITED STATES TO ANY FOREIGN PLACE OR COUNTRY.
