The outside view of the slave question in the United States, at this time, is that the extension of slavery was then arrested, circumscribed, and confined within narrow territorial limits, while free States were permitted an almost unlimited expansion. In 1822 a law passed Congress abolishing the Indian factory system, which had been established during Washington’s administration, in 1796, under which the Government acted as a factor or agent for the sale of supplies to the Indians and the purchase of furs from them; this branch of the service then belonged to the department of the Secretary of War. The abuses discovered in it led to the discontinuance of that system. The Presidential election of 1824 was approaching, the candidates were in the field, their respective friends active and busy, and popular topics for the canvass in earnest requisition. Congress was full of projects for different objects of internal improvement, mainly in roads and canals, and the friends of each candidate exerted themselves in rivalry of each other, under the supposition that their opinions would stand for those of their principals. An act for the preservation of the Cumberland Road, which passed both houses of Congress, met with a veto from President Monroe, accompanied by a state paper in exposition of his opinions upon the whole subject of Federal interference in matters of inter state commerce and roads and canals. He discussed the measure in all its bearings, and plainly showed it to be unconstitutional. After stating the question, he examined it under every head of constitutional derivation under which its advocates claimed the power, and found it to be granted by no one of them and virtually prohibited by some of them. This was then and has since been considered to be the most elaborate and thoroughly considered opinion upon the general question which has ever been delivered by any American statesman. This great state paper, delivered at a time when internal improvement by the federal government had become an issue in the canvass for the Presidency and was ardently advocated by three of the candidates and qualified by two others, had an immense current in its power, carrying with it many of the old strict constructionists.
