It should be remarked, however, that before his diplomatic career began, Franklin had become exceptionally familiar with the affairs of the Colonies. We have already noted his appointment as postmaster of Philadelphia in 1737. This experience led to his employment by the Postmaster-General of the Colonies in regulating the accounts of that widely extended department, and to Franklin's appointment in 1753 to the head of it, which greatly increased his specific knowledge of men and affairs throughout the whole land. Besides this, he had gained some political experience as a member of the provincial General Assembly, of which he had been clerk for twenty years, and thus was well acquainted with public men and measures. The Assembly consisted of only forty members, who were in constant antagonism with the governor, James Hamilton, whom the Penns, the Proprietaries of the province, had appointed to look after their interests. This official was a narrow-minded, intriguing Englishman, while the sons of William Penn themselves were selfish and grasping men, living in England, far distant from their possessions, and regarding themselves simply as English landlords of a vast estate. Under the royal charter granted by Charles II. to William Penn, his heirs exacted £30,000 yearly from the farmers as rent for their lands,--more than they could afford to pay. But when, in 1756, at the beginning of the Seven Years' War, French and Indian hostilities put the whole province in jeopardy, and it became necessary for the Provincial Legislature to tax the whole population for the common defence, the governor thought that the estates of the Proprietaries should be exempted from this just tax. Hence a collision between the legislature and the governor. The Quakers themselves, in accordance with their peace principles, were opposed to any war tax, but Franklin induced the Assembly to raise sixty thousand pounds to support the war, then conducted by General Braddock, while he himself secured a large number of wagons for the use of the army across the wilderness. Meanwhile the Assembly was involved in fresh disputes with the governor. Although the Assembly taxed the Proprietaries but a small proportion for the defence of their own possessions, the governor was unwilling to pay even this small amount; which so disgusted Franklin that he lost his usual placidity and poured out such a volley of angry remonstrances that the governor resigned. His successor fared no better with the angry legislature, and it became necessary to send some one to England to lay the grievances of the Colonists before the government, and to obtain relief from Parliament.
