Supposing the number of slaves to be 1,500,000, and their price to average 400 dollars, the cost of the whole would be 600 millions of dollars. These estimates are probably beyond the fact; and from the number of slaves should be deducted; 1. Those whom their masters would not part with. 2. Those who may be gratuitously set free by their masters. 3. Those acquiring freedom under emancipating regulations of the States. 4. Those preferring slavery where they are to freedom in an African settlement. On the other hand, it is to be noted that the expense of removal and settlement is not included in the estimated sum; and that an increase of the slaves will be going on during the period required for the execution of the plan. On the whole, the aggregate sum needed may be stated at about six hundred millions of dollars. This will require 200 millions of acres, at three dollars per acre; or 300 millions at two dollars per acre; a quantity which, though great in itself, is perhaps not a third part of the disposable territory belonging to the United States. And to what object so good, so great, and so glorious, could that peculiar fund of wealth be appropriated? Whilst the sale of territory would, on one hand, be planting one desert with a free and civilized people, it would, on the other, be giving freedom to another people, and filling with them another desert. And if in any instance wrong has been done by our forefathers to people of one colour, by dispossessing them of their soil, what better atonement is now in our power than that of making what is rightfully acquired a source of justice and of blessings to a people of another colour? As the revolution to be produced in the condition of the negroes must be gradual, it will suffice if the sale of territory keep pace with its progress. For a time, at least, the proceeds would be in advance. In this case, it might be best, after deducting the expense incident to the surveys and sales, to place the surplus in a situation where its increase might correspond with the natural increase of the unpurchased slaves. Should the proceeds at any time fall short of the calls for their application, anticipations might be made by temporary loans, to be discharged as the land should find a market.
