The debate in the Senate upon the Wilmot proviso, which immediately ensued, was cut short by the expiration of the Session of Congress--and the Bill accordingly failed of passage. In February, 1848, the treaty of Guadalupe Hidalgo was made between Mexico and the United States, and Peace reigned once more. About the same time a Bill was passed by the Senate providing Territorial Governments for Oregon, California and New Mexico, which provided for the reference of all questions touching Slavery in such Territories to the United States Supreme Court, for arbitration. The Bill, however, failed in the House. The ensuing Presidential campaign resulted in the election of General Taylor, the Whig candidate, who was succeeded upon his death, July 10, 1850, by Fillmore. Meanwhile, on the Oregon Territory Bill, in 1848, a strong effort had been made by Mr. Douglas and others to incorporate a provision extending to the Pacific Ocean the Missouri Compromise line of 36 30' of north latitude and extending to all future organizations of Territories of the United States the principles of said Compromise. This provision was adopted by the Senate, but the House struck it from the Bill; the Senate receded, and Oregon was admitted as a Free Territory. But the conflict in Congress between those who would extend and those who would restrict Slavery still continued, and indeed gathered vehemence with time. In 1850, California was clamoring for admission as a Free State to the Union, and New Mexico and Utah sought to be organized under Territorial Governments. In the heated discussions upon questions growing out of bills for these purposes, and to rectify the boundaries of Texas, it was no easy matter to reach an agreement of any sort. Finally, however, the Compromise of 1850, offered by Mr. Clay, was practically agreed to and carried out, and under it: California was admitted as a Free State; New Mexico and Utah were admitted to Territorial organization without a word pro or con on the subject of Slavery; the State of Texas was awarded a pecuniary compensation for the rectification of her boundaries; the Slave Trade in the District of Columbia was abolished; and a more effectual Fugitive Slave Act passed.
