The first of these measures was a Navigation Act, approved March 1, 1817, imposing on foreign vessels the same restrictions and prohibitions which were imposed by foreign nations on Americans. The second resembled the first in its object, but related only to the importation of plaster of Paris from Nova Scotia and New Brunswick. These two Acts began a struggle against the foreign navigation systems, which ended in their overthrow.

For the present the House postponed the establishment of an Interior Department, and allowed the Attorney-General to remain without an office or a clerk; but it passed an Act, approved March 3, 1817, concentrating in the Treasury the accounting business of government, and appointing four more auditors and one more comptroller for the purpose.

The fourth and most important measure that became law was a Neutrality Act, approved March 3, 1817, which authorized collectors of customs to seize and detain “any vessel manifestly built for warlike purposes, ... when the number of men shipped on board, or other circumstances, shall render it probable that such vessel is intended by the owner” to cruise against the commerce of a friendly State. Nearly fifty years were to pass before the people of the United States learned to realize the full importance of this Act, which laid the foundation for all the subsequent measures taken by the United States and Great Britain for preserving neutrality in their relations with warring countries.[151] The Neutrality Act of 1817 furnished the measure of neutral obligations.

Besides these important laws, the Fourteenth Congress passed another bill, which closed its own activity and that of President Madison. None of the previous measures bore any direct relation to party politics, either past or future; but the bill for internal improvements, which Congress passed and the President vetoed, was an event of no small meaning in party history.

Calhoun moved, December 16, “that a committee be appointed to inquire into the expediency of setting apart ... a permanent fund for internal improvement.” The committee was appointed the same day,—Calhoun, Sheffey of Virginia, Creighton of Ohio, Grosvenor of New York, and Ingham of Pennsylvania. December 23 Calhoun reported a bill[152] setting aside the bonus paid by the Bank, $1,500,000, and the future dividends from Bank stock, “as a fund for constructing roads and canals.” February 4 he introduced his bill by a speech, showing that a system of internal improvements was necessary, and could, in certain instances, be created by the national government alone.

“Let it not be forgotten,” said Calhoun,[153] with the air of sombre forecast which marked his mind and features, “let it be forever kept in mind, that the extent of our republic exposes us to the greatest of all calamities, next to the loss of liberty, and even to that in its consequence,—disunion. We are great, and rapidly—I was about to say fearfully—growing. This is our pride and danger, our weakness and our strength. Little does he deserve to be intrusted with the liberties of this people, who does not raise his mind to these truths. We are under the most imperious obligation to counteract every tendency to disunion.... If ... we permit a low, sordid, selfish, and sectional spirit to take possession of this House, this happy scene will vanish. We will divide, and in its consequences will follow misery and despotism.”

The Constitutional question Calhoun reserved for the future; he thought it scarcely worth discussion, since the good sense of the States might be relied on to prevent practical evils. Nevertheless he discussed it, and drew sufficient authority from the “general welfare” clause, and from the power to “establish” post-roads. Granting that the Constitution was silent, he saw no restraint on Congress:—

“If we are restricted in the use of our money to the enumerated powers, on what principle can the purchase of Louisiana be justified?... If it cannot, then are we compelled either to deny that we had the power to purchase, or to strain some of the enumerated powers to prove our right.”

The debate was interesting. Timothy Pickering, with the accumulated experience of seventy years, suggested that the right to regulate commerce among the several States, as in the case of light-houses and beacons, covered the proposed appropriation. Clay supported the bill with his usual energy, avowing that among his strongest motives was the wish to add this new distinction to the Fourteenth Congress, so harshly judged by the people. The chief Constitutional argument against the measure was made by Philip P. Barbour of Virginia; but other members opposed it on different grounds, and chiefly because as long as the internal taxes were still exacted, internal improvements should not be undertaken.

If the final vote was a correct test, Constitutional objections had but little weight with Congress. The bill passed the House, February 8, by the small majority of eighty-six to eighty-four. Of the minority no less than thirty-three were New England Federalists, whose opposition was founded on local and sectional reasons. From the slave States about forty-two votes were given against the bill; but a number of these were Federalist, and others were influenced by peculiar reasons. Two thirds of the Virginians voted against the bill; two thirds of the South Carolinians voted in its favor. Probably not more than twenty-five or thirty members, in the total number of one hundred and seventy, regarded the Constitutional difficulty as fatal to the bill.
