When Franklin came home he was fifty-six years old. By nature he was physically indolent, and fifteen years ago he had given proof of his desire for the command of his own time by retiring from a lucrative business. But his forecasting of a tranquil, social career in Philadelphia, with science as his chief and agreeable occupation, was still to continue a day-dream, interrupted only by some thoughts of an English home. "Business, public and private, consumes all my time; I must return to England for repose. With such thoughts I flatter myself, and need some kind friend to put me often in mind that old trees cannot safely be transplanted." Thus he wrote to Mary Stevenson, the young lady whom he had hoped to have as a daughter-in-law. His first labor in the provinces came in the shape of a journey about the country to supervise and regulate the postal business. Upon this errand he went 1600 miles, which was no slight matter as travel was conducted in those days. He started in the spring of 1763, and did not get back until November. Upon his return he found himself at once immersed in public affairs. In October, 1763, Governor Hamilton was superseded by John Penn, nephew of the proprietary Thomas Penn. "Never," said Franklin, "did any administration open with a more promising prospect than this of Governor Penn. He assured the people in his first speeches of the proprietaries' paternal regard for them, and their sincere dispositions to do everything that might promote their happiness. As the proprietaries had been pleased to promote a son of the family to the government, it was thought not unlikely that there might be something in these professions; for that they would probably choose to have his administration made easy and agreeable, and to that end might think it prudent to withdraw those harsh, disagreeable, and unjust instructions, with which most of his predecessors had been hampered. The Assembly therefore believed fully and rejoiced sincerely. They showed the new governor every mark of respect and regard that was in their power. They readily and cheerfully went into everything he recommended to them."
