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.

The relations between the two countries had now arrived at a point so significant that Franklin returned to his long neglected home. His person was not safe in England—his services were needed in his now suffering country. He arrived in Philadelphia early in May 1775. He was received with great enthusiasm and immediately elected to the Continental Congress. To this august body he added fresh lustre and dignity. In England he had exhausted every source of prospective reconciliation between the two nations. He feared the colonies were too weak to achieve their Independence but his course was right onward with his colleagues—resolved on liberty or death.

The talents of Franklin were put in constant requisition. He was always selected to meet the agents of the crown who were at various times commissioned to offer terms of inglorious peace. He always proved himself the uncompromising advocate of Liberty—the shrewd and wary politician—the bold and zealous defender of the rights of his bleeding country—the unflinching friend of universal freedom.

The disasters of the American army during the campaign of 1777, induced Congress to apply to France for aid. All eyes were turned on Franklin to execute this important mission. In October 1777 he embarked to perform this delicate embassy and succeeded in concluding a treaty of alliance with that nation on the 4th of February 1778, to the great joy of himself and his suffering countrymen. When the news of the alliance reached England, the ministry was much alarmed and despatched messengers to Paris to endeavor to induce Franklin to enter into a compromise with Great Britain. The terms rendered the effort too abortive to make him the bearer of even a message to Congress. To Mr. Hutton and others who came to him with the olive branch of peace, wreathed with scorpions, he replied—"I never think of your ministry and their abettors, but with the image strongly painted in my view of their hands red and dropping with the blood of my countrymen, friends and relations. No peace can be signed with those hands unless you drop all pretensions to govern us—meet us on equal terms and avoid all occasions of future discord."

He met all their intrigues at the threshold and convinced them that the hardy yoemanry of America could not be dragooned, flattered or driven from the bold position they had assumed. During the several interviews he had with these commissioners, Franklin was cautioned by Mr. Heartley to beware of his personal safety which had been repeatedly threatened. He thanked his friend and assured him he felt no alarm—that he had nearly finished a long life and that the short remainder was of no great value and ironically remarked—"Perhaps the best use such an old fellow can be put to is to make a martyr of him."

If it required all the skill and energy of a Franklin to negotiate a treaty of alliance with France, it required the combined skill of all Congress to preserve it. The French is the most effervescent nation known to history. A republican form of government is ever repugnant to kingly power. That the French officers and soldiers in the American army would drink freely at the fountain of liberal principles no one could doubt. That the thrones of Europe would be endangered on their return was truly predicted. By this very natural course of reasoning the British ministry exerted a powerful influence against the continuation of the alliance. Franklin and his colleagues anticipated all their dark intrigues—penetrated and frustrated them up to the time Great Britain was compelled to comply with the terms of an honorable peace and acknowledge the Independence of the United States of America by a definitive treaty of peace concluded at Paris on the 3d of September 1783.

Although anxious to be discharged from further public service it was not until 1785 that Franklin was permitted to return to his beloved country where he could breathe the pure air of republican freedom—no longer polluted by kingly power. During his stay he concluded treaties of commerce between the United States and the Kings of Sweden and Prussia. On his departure from Europe every mark of respect was paid to him by Kings, courts, literati and by all classes of society whose adulation the loftiest ambition could desire. He was beloved by the millions—his departure was deeply regretted by all. His reputation was the personification of purity.
