_Dear Madam_,--Your letter to Mrs. Madison, containing observations addressed to my attention also, came duly to hand, as you will learn from her, with a printed copy of your plan for the gradual abolition of slavery in the United States. The magnitude of this evil among us is so deeply felt, and so universally acknowledged, that no merit could be greater than that of devising a satisfactory remedy for it. Unfortunately the task, not easy under other circumstances, is vastly augmented by the physical peculiarities[14] of those held in bondage, which preclude their incorporation with the white population; and by the blank in the general field of labour to be occasioned by their exile; a blank into which there would not be an influx of white labourers, successively taking the place of the exiles, and which, without such an influx, would have an effect distressing in prospect to the proprietors of the soil. The remedy for the evil which you have planned is certainly recommended to favorable attention by the two characteristics: 1. That it requires the voluntary concurrence of the holders of the slaves, with or without pecuniary compensation. 2. That it contemplates the removal of those emancipated, either to a foreign or distant region. And it will still further obviate objections, if the experimental establishments should avoid the neighborhood of settlements where there are slaves. Supposing these conditions to be duly provided for, particularly the removal of the emancipated blacks, the remaining questions relate to the attitude and adequacy of the process by which the slaves are at the same time to earn the funds, entire or supplemental, required for their emancipation and removal; and to be sufficiently educated for a life of freedom and of social order. With respect to a proper course of education, no serious difficulties present themselves. And as they are to continue in a state of bondage during the preparatory period, and to be within the jurisdiction of States recognizing ample authority over them, a competent discipline cannot be impracticable. The degree in which this discipline will enforce the needed labour, and in which a voluntary industry will supply the defect of compulsory labour, are vital points, on which it may not be safe to be very positive without some light from actual experiment.
