its source;
and this was effected."

Texas quickly consented to the Act of annexation, and in December, 1845,
a Joint Resolution formally admitting her as a State of the Union,
reported by Stephen A. Douglas, was duly passed.

In May, 1846, the American forces under General Taylor, which had been
dispatched to protect Texas from threatened assault, were attacked by
the Mexican army, which at Palo Alto was badly defeated and at Resaca de
la Palma driven back across the Rio Grande.

Congress immediately declared that by this invasion a state of War
existed between Mexico and the United States. Thus commenced the War
with Mexico--destined to end in the triumph of the American Army, and
the acquisition of large areas of territory to the United States. In
anticipation of such triumph, President Polk lost little time in asking
an appropriation of over two million dollars by Congress to facilitate
negotiations for peace with, and territorial cession from, Mexico. And
a Bill making such appropriation was quickly passed by the House of
Representatives--but with the following significant proviso attached,
which had been offered by Mr. Wilmot: "Provided. That as an express and
fundamental condition to the acquisition of any territory from the
Republic of Mexico by the United States, by virtue of any treaty that
may be negotiated between them, and to the use by the Executive of the
moneys herein appropriated, neither Slavery nor involuntary servitude
shall ever exist in any part of said territory, except for crime,
whereof the party shall first be duly convicted."

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
