Their attack on the liberties of the province was well timed; for, the English forces having been everywhere defeated, the Assembly felt that it must assist in the prosecution of the war at all hazards. It therefore resolved to waive its rights for the present, and passed a bill for raising thirty thousand pounds to be expended under the joint supervision of the Assembly and the governor. So the proprietors gained one of their points, and they soon gained another. The Assembly was before long obliged to raise more money, and voted one hundred thousand pounds, the largest single appropriation ever made. It was to be raised by a general tax, and the tax was to include the proprietary estates. The governor objected, and the Assembly, influenced by the terrible necessities of the war, yielded and passed the bill in February, 1757, without taxing the estates. But it was determined to carry on its contest with the governor in another way, and resolved to send two commissioners to England to lay before the king and Privy Council the conduct of the proprietors. The first avowed object of the commissioners was to secure the taxing of the proprietary estates, and the second was to suggest that the proprietorship be abolished and the province taken under the direct rule of the crown. Franklin and Isaac Norris, the Speaker of the Assembly, were appointed commissioners, but Norris being detained by ill health, Franklin started alone. He set forth as a sort of minister plenipotentiary to London, where he had at one time worked as a journeyman printer. He had left London an obscure, impoverished boy; he was returning as a famous man of science, retired from worldly business on an assured income. He remained in England for five years, and so full of pleasure, interesting occupation, and fame were those years that it is remarkable that he was willing to come back to Pennsylvania. He secured lodgings for himself and his son William at Mrs. Stevenson’s, No. 7 Craven Street. Here he lived all of the five years and also during his subsequent ten years’ residence in London. He had been recommended to her house by some Pennsylvania friends who had boarded there; but he soon ceased to be a mere lodger, and No. 7 Craven Street became his second home. He and Mrs. Stevenson became firm friends, and for her daughter Mary he formed a strong attachment, which continued all his life. His letters to her are among the most beautiful ever written by him, and he encouraged her to study science. “In all that time,” he once wrote to her, referring to the happy years he had spent at her mother’s house, “we never had among us the smallest misunderstanding; our friendship has been all clear sunshine, without the least cloud in its hemisphere.”
