Dr. Evans' idea of establishing a medical library at the Hospital was so grateful to Franklin's untiring public spirit that, as soon as he heard of it from Dr. Evans, he sent him at once the only medical book that he had, and took steps to solicit other donations of such books for the purpose in England. There are some instructive observations on political and medical subjects in his earlier letters to Dr. Evans, but his later ones are mainly given over to the movement for the production of silk in Pennsylvania in which Dr. Evans was deeply interested. The industry, intelligence and enthusiasm with which Franklin seconded his efforts to make the exotic nursling a success is one of the many laudable things in his career. Another close friend of Franklin was Abel James, a Quaker, and an active member of the society in Pennsylvania for the manufacture of silk, or the Filature, as it was called. When he returned to England in 1764, Abel James, Thomas Wharton and Joseph Galloway were the friends who were so loath to part with him that they even boarded his ship at Chester, and accompanied him as far as New Castle. The enduring claim of James upon the attention of posterity consists in the fact that he was so lucky, when the books and papers, entrusted by Franklin to the care of Joseph Galloway were raided, as to recover the manuscript of the first twenty-three pages of the _Autobiography_, which brought the life of Franklin down to the year 1730. Subsequently he sent a copy to "his dear and honored friend," with a letter urging him to complete the work. "What will the world say," he asked, "if kind, humane and benevolent Ben. Franklin should leave his friends and the world deprived of so pleasing and profitable a work; a work which would be useful and entertaining not only to a few, but to millions?" The names of Thomas Wharton and Samuel Wharton, two Philadelphia friends of Franklin, are more than once coupled together in Franklin's letters. Thomas Wharton was a partner of Galloway and Goddard in the establishment of the _Philadelphia Chronicle_. It was his woollen gown that Franklin found such a comfortable companion on his winter voyage. He would seem to have been the same kind of robust invalid as the neurasthenic who insisted that he was dying of consumption until he grew so stout that he had to refer his imaginary ill-health to dropsy.
