The author of a poem, entitled, ‘The Dying Negro,’ has introduced these lines into that poem:[218a] “Oft have I seen them, at the break of day, “Rous’d by the lash, go forth their cheerless way.” No man ever held the slave-trade, and the condition of the hapless people who are the objects of that nefarious traffic, in greater abhorrence, than the benevolent Rittenhouse: a passage in his Oration, fully evinces his sentiments on this subject. In addition to this highly respectable testimony against Negro Slavery, let it be remembered, that one of the last acts, of a public nature, in which our philosopher’s predecessor[218b] was concerned, was to sanction with his name the Memorial presented to the government of the United States, on the subject of the Slave-Trade, by “The Pennsylvania Society for promoting the Abolition of Slavery, and the relief of free Negroes, unlawfully held in Bondage;” of which Society, that distinguished man was the President. Footnote 218a: It was written by Mr. Day, the friend of Mr. Darwin. Footnote 218b: Dr. Franklin. ----- In the year following, the tracing of a meridian, northward, for the western boundary of Pennsylvania,—and, consequently, the eastern boundary of part of Virginia,—was commenced, from the western end of the southern line of Pennsylvania before mentioned. On this occasion, Mr. Rittenhouse addressed the following letter to Mr. Ellicott. “_Philadelphia, April 28th, 1785._ “Dear Sir, “For some months past I had not the least apprehension of being obliged to visit the Ohio, this spring; but our affairs have taken such a turn, that at present it is probable I shall meet you, at the time and place appointed. Capt. Hutchins has been sent for to New York, by Congress, as the trustees of the university will not consent to Dr. Ewing’s absence. One or other of us will certainly set off in a few days, to meet you: our waggons are already gone. “I have earnestly recommended to council to commission you to act in behalf of Pennsylvania,[219] after we pass the Ohio; and the president directs me to inform you, that they mean to send you a commission for the purpose: I hope it will suit your convenience. “I ought long since to have informed you, that you were elected a member of our Philosophical Society—I wish you would favour us with a communication, on any subject you please. Pray let me hear from you, before you leave Baltimore. Have you any account from Virginia? I am, dear sir, yours with respect and sincerity. “DAVID RITTENHOUSE. “ANDREW ELLICOTT, Esq. Baltimore.” ----- Footnote 219:
