The administration inherited two serious boundary controversies, one with England, and another with Spain. Some progress had been made toward running the northeast boundary, till in 1818 the commissioners disagreed. The northwest boundary had now come to be more important. A few months before the annexation of Louisiana, Jefferson had sent an expedition to explore the country drained by the Columbia River, which had been discovered by a Boston ship in 1791. This expedition, under Lewis and Clark, in 1805 reached tributaries of the Columbia and descended it to its mouth, anticipating a similar English expedition. Nevertheless, the Hudson's Bay Company established trading-posts in the region. Monroe settled the difficulty for the time being by a treaty with Great Britain in 1818, providing that the disputed region lying between the Rocky Mountains and the Pacific Ocean and extending indefinitely northward should be jointly occupied by both countries. At the same time the northern boundary was defined from the Lake of the Woods to the Rocky Mountains.

[Sidenote: West Florida.]
[Sidenote: Spanish treaty.]

A year later another treaty with Spain gave to the United States a region which Jefferson had longed for in vain. Ever since 1803 the United States had asserted that West Florida had come to it as a part of Louisiana (§ 99). Spain steadfastly refused to admit this construction or to sell the province. In 1810 Madison by proclamation took possession of the disputed region, and a part of it was soon after added to Louisiana. East Florida could not possibly be included within Louisiana, but as a detached peninsula it was of little value to Spain. John Quincy Adams now undertook a negotiation for the settlement of all outstanding difficulties with Spain, and on Feb. 22, 1819, a treaty was signed: East Florida was ceded for a payment of about $6,500,000, and at the same time the western boundary of Louisiana was settled. An irregular line was described from the Gulf to the forty-second parallel; it was not far distant from the watershed south and west of the tributaries of the Mississippi. Then came the triumph of the whole negotiation: Adams obtained from Spain a renunciation of all claims north of the forty-second parallel, as far west as the Pacific. Our hold upon Oregon was thus much strengthened.

125. JUDICIAL DECISIONS (1812-1824).

[Sidenote: New judges.]
[Sidenote: Authority asserted.]

Two departments of the federal government had now shown their belief that the United States was a nation which ought to exercise national powers How did it stand with the judiciary department? Of the judges of the Supreme Court appointed by Washington and Adams but two remained in office in 1817; but the new justices, as they were appointed, quietly accepted the constitutional principles laid down by Marshall, their Chief Justice and leader. Among them was Joseph Story of Massachusetts, whose mastery of legal reasoning and power of statement gave him unusual influence. After the Marbury case in 1803 (§ 96) the Court refrained for some years from delivering decisions which involved important political questions. In 1809, however, it sustained Judge Peters of the Pennsylvania District Court in a struggle for authority against the governor and legislature of that State (§ 110). The courts were victorious, and the commander of the militia, who had opposed them with armed force, was punished.

[Sidenote: Appeals taken.]
[Implied powers affirmed.]

The legislation of 1815 and 1816 showed to the Court that its view of the Constitution was accepted by the people; and it now began a series of great constitutional decisions, which put on record as legal precedents the doctrines of implied powers and of national sovereignty. In the great cases of Martin vs. Hunter's Lessee, and Cohens vs. Virginia, in 1816 and 1821, it asserted the right of the Supreme Court to take cases on appeal from the State courts, and thus to make itself the final tribunal in constitutional questions. At about the same time, in two famous cases, McCullough vs. Maryland in 1819, and Osborn et al. vs. Bank of the United States in 1824, the doctrine of implied powers was stated in the most definite manner. Both cases arose out of the attempt of States to tax the United States Bank, and the final issue was the power of Congress to charter such a bank. The doctrine laid down by Hamilton in 1791 (§ 78) was reaffirmed in most positive terms. "A national bank," said Marshall, "is an appropriate means to carry out some of the implied powers, a usual and convenient agent…. Let the end be within the scope of the Constitution, and all means which are … plainly adapted to that end, which are not prohibited,… but consistent with the letter and spirit of the Constitution, are constitutional." Although the tariff act was not tested by a specific case, the spirit of the decision reached it also.

[Sidenote: State powers limited.]
[Sidenote: Impairment of contracts.]

Having thus asserted the authority of the nation on one side, the Court proceeded to draw the boundary of the powers of the States on the other side. In a question arising out of grants of land by the Georgia legislature in the Yazoo district, it had been claimed that any such grant could be withdrawn by a subsequent legislature. The Court held in Fletcher vs. Peck, in 1810, that such a withdrawal was in contravention of the constitutional clause which forbade the States to impair the obligation of contracts. In 1819, in the celebrated case of Dartmouth College vs. Woodward, this principle was pushed to an unexpected conclusion. The legislature of New Hampshire had passed an act modifying a charter granted in colonial times to Dartmouth College. Webster, as counsel for the Board of Trustees which had thus been dispossessed, pleaded that a charter granted to a corporation was a contract which could not be altered without its consent. Much indirect argument was brought to bear upon Marshall, and eventually the Court held that private charters were contracts. The effect of this decision was to diminish the power and prestige of the State governments; but the general sentiment of the country sustained it. So united did all factions now seem in one theory of national existence that in the election of 1820 Monroe received every vote but one.
