Should any plan similar to that I have sketched be deemed eligible in itself, no particular difficulty is foreseen from that portion of the nation, which, with a common interest in the vacant territory, has no interest in slave property. They are too just to wish that a partial sacrifice should be made for the general good, and too well aware that whatever may be the intrinsic character of that description of property, it is one known to the Constitution, and, as such could not be constitutionally taken away without just compensation. That part of the nation has, indeed, shewn a meritorious alacrity in promoting, by pecuniary contributions, the limited scheme for colonizing the blacks, and freeing the nation from the unfortunate stain on it, which justifies the belief that any enlargement of the scheme, if founded on just principles, would find among them its earliest and warmest patrons. It ought to have great weight that the vacant lands in question have, for the most part, been derived from grants of the States holding the slaves to be redeemed and removed by the sale of them.
It is evident, however, that in effectuating a general emancipation of slaves in the mode which has been hinted, difficulties of other sorts would be encountered. The provision for ascertaining the joint consent of the masters and slaves; for guarding against unreasonable valuations of the latter; and for the discrimination of those not proper to be conveyed to a foreign residence, or who ought to remain a charge on masters in whose service they had been disabled or worn out, and for the annual transportation of such numbers, would require the mature deliberations of the national councils. The measure implies also, the practicability of procuring in Africa an enlargement of the district or districts for receiving the exiles sufficient for so great an augmentation of their numbers.
Perhaps the Legislative provision best adapted to the case would be an incorporation of the Colonizing Society, or the establishment of a similar one, with proper powers, under the appointment and superintendence of the National Executive.
In estimating the difficulties, however, incident to any plan of general emancipation, they ought to be brought into comparison with those inseparable from other plans, and be yielded to or not accordingly to the result of the comparison.
