In turning the matter over in my mind at that time and since, I never was able to consider the African trade upon a ground disconnected with the employment of negroes in the West Indies, and distinct from their condition in the plantations whereon they serve. I conceived that the true origin of the trade was not in the place it was begun at, but at the place of its final destination. I therefore was, and I still am, of opinion that the whole work ought to be taken up together, and that a gradual abolition of slavery in the West Indies ought to go hand in hand with anything which, should be done with regard to its supply from the coast of Africa. I could not trust a cessation of the demand for this supply to the mere operation of any abstract principle, (such as, that, if their supply was cut off, the planters would encourage and produce an effectual population,) knowing that nothing can be more uncertain than the operation of general principles, if they are not embodied in specific regulations. I am very apprehensive, that, so long as the slavery continues, some means for its supply will be found. If so, I am persuaded that it is better to allow the evil, in order to correct it, than, by endeavoring to forbid what we cannot be able wholly to prevent, to leave it under an illegal, and therefore an unreformed existence. It is not that my plan does not lead to the extinction of the slave trade, but it is through a very slow progress, the chief effect of which is to be operated in our own plantations, by rendering, in a length of time, all foreign supply unnecessary. It was my wish, whilst the slavery continued, and the consequent commerce, to take such measures as to civilize the coast of Africa by the trade, which now renders it more barbarous, and to lead by degrees to a more reputable, and, possibly, a more profitable connection with it, than we maintain at present. I am sure that you will consider as a mark of my confidence in yours and Mr. Pitt's honor and generosity, that I venture to put into your hands a scheme composed of many and intricate combinations, without a full explanatory preface, or any attendant notes, to point out the principles upon which I proceeded in every regulation which I have proposed towards the civilization and gradual manumission of negroes in the two hemispheres. I confess I trust infinitely more (according to the sound principles of those who ever have at any time meliorated the state of mankind) to the effect and influence of religion than to all the rest of the regulations put together.
