The revision of the tariff, with a view to the protection of home industry, and to the establishment of what was then called “The American System,” was one of the large subjects before Congress at the session of 1823–24, and was the regular commencement of the heated debates on that question which afterwards ripened into a serious difficulty between the federal government and some of the Southern States. The presidential election being then depending, the subject became tinctured with party politics, in which so far as that ingredient was concerned, and was not controlled by other considerations, members divided pretty much on the line which always divided them on a question of constructive powers. The protection of domestic industry not being among the powers granted, was looked for in the incidental; and denied by the strict constructionists to be a substantive term, to be exercised for the direct purpose of protection; but admitted by all at that time and ever since the first tariff act of 1789, to be an incident to the revenue raising power, and an incident to be regarded in the exercise of that power. Revenue the object, protection the incident, had been the rule in the earlier tariffs; now that rule was sought to be reversed, and to make protection the object of the law, and revenue the incident. Mr. Henry Clay was the leader in the proposed revision and the champion of the American system; he was ably supported in the House by many able and effective speakers; who based their argument on the general distress then alleged to be prevalent in the country. Mr. Daniel Webster was the leading speaker on the other side, and disputed the universality of the distress which had been described; and contested the propriety of high or prohibitory duties, in the present active and intelligent state of the world, to stimulate industry and manufacturing enterprise. The bill was carried by a close vote in both Houses. Though brought forward avowedly for the protection of domestic manufactures, it was not entirely supported on that ground; an increase of revenue being the motive with some, the public debt then being nearly ninety millions. An increased protection to the products of several States, as lead in Missouri and Illinois, hemp in Kentucky, iron in Pennsylvania, wool in Ohio and New York, commanded many votes for the bill; and the impending presidential election had its influence in its favor.
