They did it to perfection. After capturing several frigates, they approached the city of Algiers and demanded the immediate surrender of every American prisoner, full indemnity for all property destroyed, and the disavowal of all future claims to tribute. The terrified Dey eagerly signed the treaty placed before him on the quarter-deck of Decatur's ship. The Pasha of Tunis was compelled to pay a round sum on account of the American vessels he had allowed the British to capture in his harbor during the war. When he had done this, the Pasha of Tripoli was called upon and forced to make a similar contribution to the United States treasury. FOUNDING OF THE NATIONAL COLONIZATION SOCIETY. The negro had long been a disturbing factor in politics, and, in 1816, the National Colonization Society was formed in Princeton, N.J., and immediately reorganized in Washington. Its object was to encourage the emancipation of slaves by obtaining a place for them outside the United States, whither they might emigrate. It was hoped also that by this means the South would be relieved of its free black population. The scheme was so popular that branches of the society were established in almost every State. At first free negroes were sent to Sierra Leone, on the western coast of Africa, under the equator. Later, for a short time, they were taken to Sherbrooke Island, but in 1821 a permanent location was purchased at Cape Mesurado, where, in 1847, the colony declared itself an independent republic under the name of Liberia. Its capital, Monrovia, was named in honor of the President of the United States. The republic still exists, but its functions were destroyed by the war for the Union, which abolished slavery on this continent, and Liberia has never been looked upon with great favor by the colored people of this country. PRESIDENTIAL ELECTION OF 1816. It has already been shown that the course of the Federal party in the War of 1812 ruined it. The Federal nominee for the presidency was Rufus King, of New York. He was a native of Maine, a graduate of Harvard College, and had served as a delegate to the Continental Congress. It was he who in 1785 moved the provision against slavery in the Northwest Territory, and he was an active member of the Constitutional Convention of 1787, afterward returning to Massachusetts and giving all his energies to bringing about the ratification of the Constitution. He was United States senator from New York in 1789-1796; was minister to London, 1796-1803; and again a United States senator, 1813-1825.
