Franklin sailed again for America in August 1762, hoping to be able to settle down in quiet and devote the remainder of his life to experiments in physics. This quiet was interrupted, however, by the "Paxton Massacre" (Dec. 14, 1763)--the slaughter of a score of Indians (children, women and old men) at Lancaster, Pennsylvania, by some young rowdies from the town of Paxton, who then marched upon Philadelphia to kill a few Christian Indians there. Franklin, appealed to by the governor, raised a troop sufficient to frighten away the "Paxton boys," and for the moment there seemed a possibility of an understanding between Franklin and the proprietors. But the question of taxing the estates of the proprietors came up in a new form, and a petition from the assembly was drawn by Franklin, requesting the king "to resume the government" of Pennsylvania. In the autumn election of 1764 the influence of the proprietors was exerted against Franklin, and by an adverse majority of 25 votes in 4000 he failed to be re-elected to the assembly. The new assembly sent Franklin again to England as its special agent to take charge of another petition for a change of government, which, however, came to nothing. Matters of much greater consequence soon demanded Franklin's attention. Early in 1764 Lord Grenville had informed the London agents of the American colonies that he proposed to lay a portion of the burden left by the war with France upon the shoulders of the colonists by means of a stamp duty, unless some other tax equally productive and less inconvenient were proposed. The natural objection of the colonies, as voiced, for example, by the assembly of Pennsylvania, was that it was a cruel thing to tax colonies already taxed beyond their strength, and surrounded by enemies and exposed to constant expenditures for defence, and that it was an indignity that they should be taxed by a parliament in which they were not represented; at the same time the Pennsylvania assembly recognized it as "their duty to grant aid to the crown, according to their abilities, whenever required of them in the usual manner." To prevent the introduction of the Stamp Act, which he characterized as "the mother of mischief," Franklin used every effort, but the bill was easily passed, and it was thought that the colonists would soon be reconciled to it. Because he, too, thought so, and because he recommended John Hughes, a merchant of Philadelphia, for the office of distributor of stamps, Franklin himself was denounced--he was even accused of having planned the Stamp Act--and his family in Philadelphia was in danger of being mobbed. Of Franklin's examination, in February 1766, by the House in Committee of the Whole, as to the effects of the Stamp Act, Burke said that the scene reminded him of a master examined by a parcel of schoolboys, and George Whitefield said: "Dr Franklin has gained immortal honour by his behaviour at the bar of the House.
