When he reached manhood he also developed a strong inclination to assist in public improvements, in the encouragement of thrift and comfort, and in the relief of suffering, subjects which are now included under the heads of philanthropy and reform. He had in full measure the social and public spirit of the Anglo-Saxon, the spirit which instinctively builds up the community while at the same time it is deeply devoted to its own concerns. The only one of his ancestors that had risen above humble conditions was of this sort, and had been a leader in the public affairs of a village. His natural disposition towards benevolent enterprises was much stimulated, he tells us, by a book called “Essays to do Good,” by the eminent Massachusetts divine, Cotton Mather, of witchcraft fame. He also read about the same time De Foe’s “Essay upon Projects,” a volume recommending asylums for the insane, technical schools, mutual benefit societies, improved roads, better banking, bankrupt laws, and other things which have now become the commonplace characteristics of our age. His club, the Junto, was the first important fruit of this benevolent disposition. At first its members kept all their books at its rooms for the common benefit; but some of the books having been injured, all were taken back by the owners, and this loss suggested to Franklin the idea of a circulating library supported by subscriptions. He drew up a plan and went about soliciting money in 1731, but it took him more than a year to collect forty-five pounds. James Logan, the secretary of the province, gave advice as to what books to buy, and the money was sent to London to be expended by Mr. Peter Collinson, to whom Franklin’s famous letters on electricity were afterwards written. Mr. Collinson was the literary and philosophic agent of Pennsylvania in those days. To him John Bartram, the first American botanist, sent the plants that he collected in the New World, and Mr. Collinson obtained for him the money with which to pursue his studies. Collinson encouraged the new library in every way. For thirty years he made for it the annual purchase of books, always adding one or two volumes as a present, and it will be remembered that it was through him that Franklin obtained the electrical tube which started him on his remarkable discoveries.
