The two years which followed were among the busiest of his life. The very morning of his arrival he was elected, by the assembly of Pennsylvania, a delegate to that continental congress then sitting in Philadelphia which consolidated the armies of the colonies, placed George Washington in command of them, issued the first continental currency, and assumed the responsibility of resisting the imperial government. In this congress he served on not less than ten committees. One of its first measures was to organize a continental postal system and to make Franklin postmaster-general. Thus he was avenged for his dismissal 18 months before from the office of deputy by being appointed to a place of higher rank and augmented authority. He planned all appeal for aid from the king of the French, and wrote the instructions of Silas Deane, a member of the congress, who was to convey it; he was sent as one of three commissioners to Canada, in one of the most inclement months of the year, on what proved an in effectual mission to persuade the Canadians to join the new colonial union; he was elected a delegate from Philadelphia to the conference which met on the 18th of June 1776, and which, in the name of the people of the colonies, formally renounced all allegiance to King George, and called for an election of delegates to a convention to form a constitutional government for the United Colonies. He was also one of the committee of five which drew up what is known as the "Declaration of Independence." When about to sign it, Hancock, one of his colleagues, is reported to have said, "We must be unanimous; there must be no pulling different ways; we must all hart; together." "Yes," replied Franklin, "we must hang together, or we will be pretty sure to hang separately." He was also chosen president of the convention called to frame a constitution for the State of Pennsylvania, which commenced its session on the 16th of July 1776. He was selected by congress to discuss terms of peace with Admiral Lord Howe, who had arrived in New York harbour on the 12th of July 1776, to take command of the British naval forces in American waters, and on the 26th of September, upon the receipt of encouraging news from France, he was chosen unanimously to be one of three to repair to the court of Louis XVI. and solicit his support. His colleagues were John Adams, destined to be Washington's successor in the presidency, and Arthur Lee, Franklin's successor in the agency in London.
