He had invested some of his savings in houses and land in Philadelphia, and the thousand pounds (five thousand dollars) which he was to receive for eighteen years was a very good income in those times, and more than equivalent to ten thousand dollars at the present day. He moved from the bustle of Market Street and his home in the old printing, stationery, and grocery house, and is supposed to have taken a house at the southeast corner of Second and Race Streets. This was at the northern edge of the town, close to the river, where in the summer evenings he renewed his youthful fondness for swimming. It must be confessed that very few self-made men, conducting a profitable business with the prospect of steady accumulation of money, have willingly resigned it in the prime of life, under the influence of such sentiments as appear to have moved him. But that intense and absolute devotion to business which is the prevailing mood of our times had not then begun in America, and it was rather the fashion to retire. The years which followed his retirement, and before he became absorbed in political affairs, seem to have had for him a great deal of ideal happiness. He lived like a man of taste and a scholar accustomed to cultured surroundings more than like a self-made man who had battled for forty years with the material world. In writing to his mother, he said,-- “I read a great deal, ride a little, do a little business for myself, now and then for others, retire when I can, and go into company when I please; so the years roll round, and the last will come, when I would rather have it said, He lived usefully than He died rich.” After his withdrawal from business he remained postmaster of Philadelphia, and in 1753, after he had held that office for sixteen years, he was appointed Postmaster-General of all the colonies, with William Hunter, of Virginia, as his colleague, and he retained this position until dismissed from it by the British government in 1774, on the eve of the Revolution. There was some salary attached to these offices, that of Postmaster-General yielding three hundred pounds. The postmastership of Philadelphia entailed no difficult duties at that time, and his wife assisted him; but when he was made Postmaster-General he more than earned his salary during the first few years by making extensive journeys through the colonies to reform the system. The salary attached to the office was not to be allowed unless the office produced it; and during the first four years the unpaid salary of Franklin and his colleague amounted to nine hundred and fifty pounds. He procured faster post-riders, increased the number of mails between important places, made a charge for carrying newspapers, had all newspapers carried by the riders, and reduced some of the rates of postage.
