piracies of their seas and the cannibalisms of the African coasts, and to us, the suppression of the same enormities within our seas; and for this purpose, I should rejoice to see the fleets of Brazil and the United States riding together as brethren of the same family, and pursuing the same object. And indeed it would be of happy augury to begin at once this concert of action here, on the invitation of either to the other government, while the way might be preparing for withdrawing our cruisers from Europe, and preventing naval collisions there which daily endanger our peace. * * * * * Accept assurances of the sincerity of my friendship and respect for you. TO DOCTOR COOPER. MONTICELLO, August 14, 1820. DEAR SIR,--Yours of the 24th ult. was received in due time, and I shall rejoice indeed if Mr. Elliot and Mr. Nulty are joined to you in the institution at Columbia, which now becomes of immediate interest to me. Mr. Stack has given notice to his first class that he shall dismiss them on the 10th of the next month, and his mathematical assistant also at the same time, being determined to take only small boys in future. My grandson, Eppes, is of the first class; and I have proposed to his father to send him to Columbia, rather than anywhere northwardly. I am obliged, therefore, to ask of you by what day he ought to be there, so as to be at the commencement of what they call a session, and to be so good as to do this by the first mail, as I shall set out to Bedford within about a fortnight. He is so far advanced in Greek and Latin that he will be able to pursue them by himself hereafter; and being between eighteen and nineteen years of age he has no time to lose. I propose that he shall commence immediately with the mathematics and natural philosophy, to be followed by astronomy, chemistry, mineralogy, botany, natural history. It would be time lost for him to attend professors of ethics, metaphysics, logic, &c. The first of these may be as well acquired in the closet as from living lectures; and supposing the two last to mean the _science of mind_, the simple reading of Locke, Tracy, and Stewart, will give him as much in that branch as is _real_ science. A relation of his (Mr. Baker) and classmate will go with him.
