In 1753 he was sent to Carlisle, Pennsylvania, to conclude a treaty with the Indians. In 1754 he was a delegate to the Congress of Commissioners which met at Albany to devise means of defence against the anticipated hostilities of the French and savages. He then submitted a plan that was unanimously approved by the Congress but was too republican for the creatures of the king. On the decease of the Deputy Postmaster-General of America, Franklin was appointed to fill the vacancy and raised the department from embarrassment to a fruitful source of revenue to the crown. Difficulties arose between the proprietaries and government of the province of Pennsylvania, which were referred to the mother country for adjustment. Dr. Franklin was sent by the province to guard its interests and embarked for England in June 1757. He executed the duties of his mission with his usual ability and address--the difficulties were settled and in 1762 he returned. He was then variously employed--regulating the Post-Office Department--making treaties with the Indians and devising means of defence on the frontiers. New troubles arose between the proprietaries and assembly and in 1764 Dr. Franklin again sailed for England, with instructions to obtain the entire abolishment of proprietary authority. On his arrival he was called upon to perform more important and perilous duties. The plan for taxing the colonies had been long agitated and was now matured by the British ministry. This project he had boldly opposed at the threshold and was now arraigned to answer numerous accusations brought against him by the enemies of liberty. On the 3d of February 1766, he appeared before the House of Commons to undergo a public examination. He was found equal to the task--his enemies were astounded at his boldness, logic, dignity and skill, whilst his friends were filled with admiration at the able manner he confuted every accusation and defended the rights and interests of his native country. Amidst the attacks of artifice and insolence of power he stood unawed--unmoved--firm as a granite rock. He remained in England eleven years as the agent of the colonies, opposing the encroachments of the ministry upon the rights of Americans. During the whole time the combined efforts of flattery, malice and intrigue could not intimidate or ensnare him. He well understood the etiquette, corruptions and devices of diplomacy. He never bowed his knee to Baal or kissed the hand of a king.
