decrease in the existing total of coloured population will ensue. This I know will be denied--but I appeal to facts as the best data for my conclusions. Let us then remember that by official returns, the emigration from the United Kingdom was 76,000 last year. And have not our poor blacks quite as many reasons for seeking an asylum in that growing realm--so emphatically their own--from the increasing severity of Southern laws, and the horrors of Northern mobs? Will not this be the more extensively felt, as these African States open up new channels to profitable industry, until the emigration shall reach 56,000 per annum--which was the average yearly increase of the whole coloured population during the ten years from 1820 to 1830? And when we recollect that they would, under our system, be wafted thither free of expense to themselves, there is every reason to believe their numbers would soon equal the British emigration, which is in most cases at the proper cost of the parties themselves. If only that point was reached, an access of 20,000 per annum would accrue beyond the present natural increase, and thus create an actual diminution in our coloured population--augmented too, by the circumstance that the emigrants would generally be of the young, the active, and the procreating class--while the relative disproportion of the races would be rapidly felt through the great increase of the whites. "I am well aware that it has been most gratuitously and absurdly asserted, 'that our whole marine is insufficient to convey to Africa this annual increase!' And yet 42,000 tons of shipping, only making two trips each year, and allowing each emigrant six times the space allowed on board the slavers--or one ton and a half each--would accommodate the whole! What then shall we say to those who assert that the annual wealth of this great nation, with a surplus of ten millions annually, is unable to carry _to_ Africa, _one_-third as many of the offspring of oppression, as a band of pirates and outlaws each year drag away in chains _from_ her shores! A late writer in Blackwood's Magazine, asserts that no less than 200,000 slaves were shipped in 1831--Walsh that 50,000 were landed at Rio Janeiro alone, in 1828. We may, then, without difficulty, colonize 100,000 annually--a number that would in thirty years transfer our whole coloured population to Africa, by an outlay of three millions of dollars yearly,--a sum which the weekly contribution of three cents by one-seventh of our people, would supply; or, if voted as a measure of justice for the many wrongs received at our hands by poor Africa and her children, would afford a safe mode of depleting our overburdened treasury."
