The theatre of the war, now filled with comfortable farms and populous cities, was then less known than any of our Territories in 1896. There were no roads, and the transportation of provisions for the troops, of guns, ammunition, and stores for the lake navies, was one of the most difficult of the problems which the National Government was called upon to solve. It cannot be said that the solution was successfully reached, for the blunders in transportation were among the most costly, exasperating, and dangerous of the war. But the efforts to reach it provided the impulse which soon after resulted in the settlement of Western New York, the appearance of the germs of such flourishing cities as Buffalo, Rochester, and Syracuse, the opening up of the Southwest Territory, between Tennessee and New Orleans, and the rapid admission of the new States of Indiana, Illinois, Mississippi, and Missouri. But the impulse did not stop here. The inconveniences and dangers arising from the possession of a vast territory with utterly inadequate means of communication had been brought so plainly to public view by the war that the question of communication influenced politics in every direction. In New York it took shape in the construction of the Erie Canal (finished in 1825). In States farther west and south, the loaning of the public credit to enterprises of the nature of the Erie Canal increased until the panic of 1837 introduced "repudiation" into American politics. In national politics, the necessity of a general system of canals and roads, as a means of military defence, was at first admitted by all, even by Calhoun, was gradually rejected by the stricter constructionists of the Constitution, and finally became a tenet of the National Republican party, headed by John Quincy Adams and Clay (1825-29), and of its greater successor the Whig party, headed by Clay. This idea of Internal Improvements at national expense, though suggested by Gallatin and Clay in 1806-08, only became a political question when the war had forced it upon public attention; and it has not yet entirely disappeared.
