Afterwards Jay was appointed one of our Commissioners to negotiate the treaty of peace with Great Britain, and he and his family settled down under the same roof with Franklin at Passy. The result was a mutual feeling of attachment, so strong that when Jay returned to America Franklin could write to him of a kind letter that he had received from him: "It gave me Pleasure on two Accounts; as it inform'd me of the public Welfare, and that of your, I may almost say _our_ dear little Family; for, since I had the Pleasure of their being with me in the same House, I have ever felt a tender Affection for them, equal I believe to that of most Fathers." In other letters to Jay, there are repeated references by Franklin to the child of Jay mentioned above whose singular attachment to him, he said, he would always remember. "Embrace my little Friend for me," he wrote to Jay and his wife, when he was wishing them a prosperous return voyage to America, and, in a later letter, after his own return to America, to the same pair, he said he was so well as to think it possible that he might once more have the pleasure of seeing them both at New York, with his dear young friend, who, he hoped, might not have quite forgotten him. Beyond the Harlem River, his friends were only less numerous than they were in Pennsylvania. Among the most conspicuous were Josiah Quincy, John Winthrop, Professor of Mathematics and Natural Philosophy at Harvard College, and Dr. Samuel Cooper, the celebrated clergyman and patriot. We mention these three Boston friends of his first because they were feelingly grouped in a letter that he wrote to James Bowdoin, another valued Boston friend of his, towards the close of his life. In this letter, he tells Bowdoin that it had given him great pleasure to receive his kind letter, as it proved that all his friends in Boston were not estranged from him by the malevolent misrepresentations of his conduct that had been circulated there, but that one of the most esteemed still retained a regard for him. "Indeed," Franklin said, "you are now almost the only one left me by nature; Death having, since we were last together, depriv'd me of my dear Cooper, Winthrop, and Quincy." Winthrop, he had said, in an earlier letter to Dr. Cooper, was one of the old friends for the sake of whose society he wished to return from France and spend the small remnant of his days in New England. The friendship between Quincy and Franklin began when Franklin was a member of the Pennsylvania Assembly, and had its origin in the sum of ten thousand pounds, which Quincy, as the agent of the Colony of Massachusetts, obtained through the assistance of Franklin from the Colony of Pennsylvania for the military needs of the former colony. Quincy, Franklin said in the _Autobiography_, returned thanks to the Assembly in a handsome memorial, went home highly pleased with the success of his embassy, and ever after bore for him the most cordial and affectionate friendship.
