Franklin also made some wise suggestions to Congress with respect to the best method of preventing the depreciation of the paper money issued by it. His first suggestion was that the bills should bear interest. This suggestion was rejected. His next was that, instead of the issuance of any more paper money, what had already been issued should be borrowed back upon interest. His last was that the interest should be paid in hard money, but both of the latter suggestions, though approved by Congress, were approved too late to accomplish their objects. After due tenderness had been exhibited by him to John Dickinson and the other members of Congress, who still clung to the hope of a reconciliation with England, Franklin brought forward a plan for the permanent union and efficient government of the Colonies. Under this plan each colony was to retain its internal independence, but its external relations, especially as respected resistance to the measures of the English Ministry, were committed to an annually-elected Congress. The supreme executive authority of the union was to be vested in a council of twelve, to be elected by the Congress. Ireland, Canada, the West Indies, Bermuda, Nova Scotia and Florida as well as the thirteen colonies within the present limits of the United States, were to be invited to join the confederacy. The union was to last until British oppression ceased, and reparation was made to the Colonies for the injuries inflicted upon them; which, of course, under the circumstances, meant until the Greek Calends. The plan was referred to a committee, but it was never acted upon by the House; being too bold a project to suit the cautious scruples of John Dickinson and the other moderate members of the Continental Congress, who dreaded the effect of a project of union upon the mind of the King, while the petition of Congress to him was pending. Among other important committees upon which Franklin served, when a member of the first Continental Congress, was one to investigate the sources of saltpetre; another to treat with the Indians; another to look after the engraving and printing of the continental paper money; another to consider Lord North's conciliatory resolution; another on salt and lead; and still another to report a plan for regulating and protecting the commerce of the Colonies. At the next session of the Congress, he was equally active. Among the things in which we find him engaged at this session, are the arrangement of a system of posts and expresses for the rapid transmission of dispatches; the establishment of a line of packets between America and Europe; an effort to promote the circulation of the continental money; and the preparation of instructions for the American generals. It was at this session of Congress, too, that Thomas Lynch, of South Carolina, Benjamin Harrison, of Virginia, and himself were appointed the committee to visit Washington's camp before Boston. The journey to Boston consumed thirteen
