What Franklin did for Philadelphia, when peace prevailed, we have already seen; what he did for it, when threatened by war, remains to be told. In 1747, England was involved in a struggle with France and Spain, and the city lay at the mercy of French and Spanish privateers, all the efforts of Governor Thomas to induce the Quaker majority in the Assembly to pass a militia law and to make other provision for the security of the Province having proved wholly futile. Under these circumstances, Franklin wrote and published a pamphlet, entitled _Plain Truth_, for the purpose of arousing the people of the Province to a true sense of their perilous predicament. The pamphlet [Franklin tells us in the _Autobiography_], had a sudden and surprising effect, and we can readily believe it, for rarely has an alarum been more artfully sounded. In its pages is to be found every artifice of persuasion that could be skillfully used by an adroit pamphleteer for the purpose of playing upon the fears of his readers and inciting them to determined measures of self-defense. It began by pointing out the causes which had brought about an entire change in the former happy situation of the Province, namely its increased wealth, its defenseless condition, the familiarity acquired by its enemies with its Bay and River through prisoners, bearers of flags of truce, spies, and, perhaps, traitors, the ease with which pilots could be employed by these enemies and the known absence of ships of war, during the greatest part of the year, ever since the war began, from both Virginia and New York. That the enemies of the Province might even then have some of their spies in the Province could not be seriously doubted, it declared, for to maintain such spies had been the practice of all nations in all ages, as for example the five men sent by the Children of Dan to spy out the land of the Zidonians, and search it. (Book of Judges, Chap. XVIII, V. 2). These men, while engaged in their enterprise, met with a certain idolatrous priest of their own persuasion (would to God no such priests were to be found among the Pennsylvanians!) And, when they questioned him as to whether their way would be prosperous, he among other things said unto them, _Go in Peace; before the Lord is your Way wherein you go_. (It was well known that there were many priests in the Province of the same religion as those who, of late, encouraged the French to invade the mother country). _And they came_, (Verse 7) _to Laish, and saw the People that were therein, how they dwelt CARELESS, after the Manner of the Zidonians_, QUIET AND SECURE. They _thought_ themselves secure no doubt; and, as they _never had been_ disturbed, vainly imagined they _never should_. It was not unlikely that some saw the danger
