It was more difficult to win over the United States. There the people showed the usual indifference of a big and prosperous country to the needs or opportunities of a small and backward neighbor. The division of power between President and Congress made it difficult to carry any negotiation through to success. Yet these obstacles were overcome. The depletion of the fisheries along the Atlantic coast of the United States made it worth while, as I.D. Andrews, a United States consul in New Brunswick, urged persistently, to gain access to the richer grounds to the north and, if necessary, to offer trade concessions in exchange. At Washington, the South was in the saddle. Its sympathies were strongly for freer trade, but this alone would not have counted had not the advocates of reciprocity convinced the Democratic leaders of the bearing of their policy on the then absorbing issue of slavery. If reciprocity were not arranged, the argument ran, annexation would be sure to come and that would mean the addition to the Union of a group of freesoil States which would definitely tilt the balance against slavery for all time. With the ground thus prepared, Lord Elgin succeeded by adroit and capable diplomacy in winning over the leaders of Congress as well as the Executive to his proposals. The Reciprocity Treaty was passed by the Senate in August, 1854, and by the Legislatures of the United Kingdom, Canada, Prince Edward Island, New Brunswick, and Nova Scotia in the next few months, and of Newfoundland in 1855. This treaty provided for free admission into each country of practically all the products of the farm, forest, mine, and fishery, threw open the Atlantic fisheries, and gave American vessels the use of the St. Lawrence and Canadian vessels the use of Lake Michigan. The agreement was to last for ten years and indefinitely thereafter, subject to termination on one year's notice by either party. To both countries reciprocity brought undoubted good. Trade doubled and trebled. Each country gained by free access to the nearest sources of supply. The same goods figured largely in the traffic in both directions, the United States importing grain and flour from Canada and exporting it to the Maritime Provinces. In short the benefits which had come to the United States from free and unfettered trade throughout half a continent were now extended to practically a whole continent.
