Referring to Kosciuszko, Jefferson said:
“On his departure from the United States in 1798 he left in my hands an instrument appropriating after his death all the property he had in our public funds, the price of his military services here, to the education and emancipation of as many of the children of bondage in this country as this should be adequate to. I am now too old to undertake a business de si longue haleine; but I am taking measures to place it in such hands as will ensure a faithful discharge of the philanthropic intentions of the donor. I learn with pleasure your continued efforts for the instruction of the future generations of men, and, believing it the only means of effectuating their rights, I wish them all possible success, and to yourself the eternal gratitude of those who will feel their benefits, and beg leave to add the assurance of my high esteem and respect.”—Writings of Thomas Jefferson, Memorial Edition. 1904, vol. xv., pp. 173-174.
“Supposing these conditions to be duly provided for, particularly the removal of the emancipated blacks, the remaining questions relate to the aptitude and adequacy of the process by which the slaves are at the same time to earn 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 the proper course of education, no serious difficulties present themselves. 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.
