For his public services in France, he was allowed at first a salary of five hundred pounds a year and his expenses, and subsequently, when his rank was advanced to that of ambassador, two thousand five hundred pounds a year. When he returned from France to America, he communicated to his old friend, Charles Thomson, the Secretary of Congress, his hope that Congress might be kind enough to recognize the value of his services and sacrifices in the American cause by granting him some small tract of land in the West. He saw, he said, that Congress had made a handsome allowance to Arthur Lee for his services to America in England before his appointment as Commissioner to France, though it had made none to the writer or to Mr. Bollan, who were also parties to these services. Moreover, Lee, on his return to America, as well as John Jay, had been rewarded by Congress with a good office. The letter, of course, made out an irrefragable case; for, if the United States had given the whole Northwest Territory to Franklin, his heirs and assigns forever, the gift would hardly have exceeded the value of his services. It was written just before the Old Congress gave way to the First Congress under the Federal Constitution, and nothing ever came of it. The conduct of the Old Congress to Franklin in other respects had been so ungenerous that it is hardly likely that it would have made any response to the appeal anyhow unless solicited by a more intriguing spirit than his. The State of Georgia was more mindful of its obligations to him, and voted him the right to take up three thousand acres of land within its limits. After his return from France, a great rise took place in the value of real estate in Philadelphia, and his houses and lots reaped its benefits to a conspicuous degree. On Jan. 29, 1786, he wrote to Ferdinand Grand, "My own Estate I find more than tripled in Value since the Revolution"; and similar statements are to be found in other letters of his at this time. At this period of his life, a considerable amount of his attention was given to the improvement of his property. On Apr. 22, 1787, in a letter to Ferdinand Grand, he said, "The three Houses which I began to build last year, are nearly finished, and I am now about to begin two others. Building is an Old Man's Amusement. The Advantage is for his Posterity." When Franklin died, his estate consisted of ten houses in Philadelphia, and almost as many vacant lots, a pasture lot near Philadelphia, a farm near Burlington, New Jersey, a house in Boston, the right to the three thousand acres of land in Georgia, a tract of land on the Ohio, a tract of land in Nova Scotia, twelve shares of the capital stock of the Bank of North America and bonds of individuals in excess of eighteen thousand pounds. The value of his entire estate was supposed to be between two hundred and two hundred and fifty thousand dollars.
