This warning effectually roused the community. A public meeting was summoned, in the immense building erected to accommodate the crowds who flocked to hear Whitefield. Here Franklin harangued the multitude. An Association of Defence was organized. Ten thousand persons enrolled their names. In a few days nearly every man in the province, who was not a Quaker, had joined some military organization. Each man purchased for himself a weapon, and was learning how to use it. Eighty companies were organized and disciplined. The companies in Philadelphia united in a regiment, and chose Franklin their colonel. Wisely he declined the office, "conceiving myself unfit," he says. A battery was thrown up below the town. Some cannon were sent for from Boston. Several eighteen-pounders were obtained in New York, and more were ordered from London. In manning the battery, Franklin took his turn of duty as a common soldier. There was not a little opposition to these measures, but still the strong current of popular opinion was in their favor. Even the young Quakers, though anxious to avoid wounding the feelings of their parents, secretly gave their influence to these preparations of defence. The peace of Aix la Chapelle in 1748, terminated these alarms. But the wisdom and energy which Franklin had displayed, caused him to be regarded as the most prominent man in Pennsylvania. The masses of the people regarded him with singular homage and confidence. In 1744, Franklin had a daughter born, to whom he gave the name of Sarah. His motherless son William, who was destined to give his father great trouble, was growing up, stout, idle, and intractable. Early in the war he had run away, and enlisted on board a privateer. With much difficulty his father rescued him from these engagements. Franklin was evidently embarrassed to know what to do with the boy. He allowed him, when but sixteen years of age, to enlist as a soldier in an expedition against Canada. About this time Franklin wrote to his sister Jane, whose son had also run away to enlist as a privateer. He wished to console her by the assurance that it was not in consequence of unkind treatment, that the boys were induced thus to act. He wrote: "When boys see prizes brought in, and quantities of money shared among the men, and their gay living, it fills their heads with notions that half distract them; and puts them quite out of conceit with trades and the dull ways of getting money by working. My only son left my house unknown to us all, and got on board a privateer, from whence I fetched him. No one imagined it was hard usage at home that made him do this. Every one that knows me thinks I am too indulgent a parent, as well as master."
