mountains, would be greatly advanced in all their interests. Agricultural products and other bulky and heavy articles that could not bear transportation all the way by the great Pacific railroad, could be carried by such enlarged canals to the Mississippi and Missouri, and ultimately to the base of the Rocky mountains, and thence, by railroad, a comparatively short distance to the Pacific, and westward to China and Japan. In order to make New York and San Francisco great depots of interoceanic commerce for America, Europe, Asia, and the world, these enlarged canals, navigated by large steamers, and ultimately toll free, are indispensable. We have named, then, all the Territories, and all the thirty-five States, except three, as deriving great and special advantages from this system. These three are Georgia, South Carolina, and Florida, with a white population, in 1860, of 843,338. These States, however, would not only participate in the increased prosperity of the whole country, and in augmented markets for their cotton, rice, sugar, tobacco, and timber, and in cheaper supplies of Eastern manufactures, coal, iron, and Western products, but they would derive, also, special advantages. They have a large trade with New Orleans, which they would reach more cheaply by deepening the mouth of the Mississippi. They could pass up Albemarle sound, by the interior route, to Baltimore, Philadelphia, New York, or the West, and take back return cargoes by the same route. Georgia, also, by her location on the Tennessee river, together with South Carolina, connected with that river at Chattanooga, would derive great benefits from this connection with the enlarged canals and improved navigation of the West, sending their own and receiving Western products more cheaply. Thus, every State and every Territory in the Union would be advanced in all their interests by these great weeks, and lands, farms, factories, town and city property, all be improved in value.
