The first plan of union which he drafted was the one adopted by the Albany Conference of 1754, that had been called to make a general treaty with the Indians which would obviate the confusion of separate treaties made by the different colonies. Such a general treaty, by controlling the Indians, would, it was hoped, assist in resisting the designs of the French in Canada. It was obvious, also, that if the colonies were united under a general government they would be better able to withstand the French. Franklin had advocated this idea of union in his _Gazette_, and had published a wood-cut representing a wriggling snake separated into pieces, each of which had on it the initial letter of one of the colonies, and underneath was written, “Join or die.” He was sent to the conference as one of the delegates from Pennsylvania, and his plan of union, which was adopted, was a distinct improvement on all others that had preceded it, and contained the germs of principles which are now a fundamental part of our political system. In 1775, while a member of the Continental Congress, he drafted another plan, which, though not adopted, added new suggestions and developments. But as both of these plans are fully discussed in “The Evolution of the Constitution,”[29] it is unnecessary to say more about them here. He was a member of the convention which in 1776 framed a new constitution for Pennsylvania, and in this instrument he secured the adoption of two of his favorite ideas. He believed that a Legislature should consist of only one House, and that the executive authority, instead of being vested in a single person, should be exercised by a committee. The executive department of Pennsylvania became, therefore, a Supreme Executive Council of twelve members elected by the different counties. In order to make up for the lack of a double House, there was a sort of makeshift provision providing that every bill must pass two sessions of the Assembly before it became a law. There was also a curious body called the Council of Censors, two from each city and county, who were to see that the constitution was not violated and that all departments of government did their duty. It was a crude and awkward attempt to prevent unconstitutional legislation, and proved an utter failure. The whole constitution was a most bungling contrivance which wrought great harm to the State and was replaced by a more suitable one in 1790.
