in reference to
slavery, _affirmatively_, and in opposition to the extension of slavery!
The _latest_ record of Buchanan is in 1844, and proves him to be an
ABOLITIONIST OF THE BLACKEST DYE. About the last speech he ever made in
Congress, was IN OPPOSITION TO SLAVERY, in secret session of the Senate,
just before Mr. Polk, in opposition to the wishes of Gen. Jackson, gave
him a seat in his cabinet. This speech will be found in the
Congressional Globe for 1844, an extract from which is in these
_explicit_ and _memorable_ words:

"In arriving at the conclusion to support this treaty, I had to
encounter _but one serious obstacle_, AND THAT WAS THE QUESTION
OF SLAVERY. Whilst I have ever maintained, and ever shall
maintain, in their full force and vigor, the constitutional
rights of the Southern States over their slave property, I yet
feel a strong repugnance by any act of mine to extend the
limits of the Union over a new slaveholding territory. After
mature reflection, however, I overcame these scruples, and now

not finally pass off into Mexico, and THERE MINGLE WITH A RACE
WHERE NO PREJUDICE EXISTS AGAINST THEIR COLOR? The Mexican
nation is composed of Spaniards, Indians, and Negroes, blended
together in every variety, who would receive our slaves on
terms of perfect social equality. To this condition they never
can be admitted in the United States.

"That the acquisition of Texas would ere long convert Maryland,
Virginia, Kentucky, Missouri, and probably others of the more
Northern Slave States, into free States, I entertain not a
doubt....

"But should Texas be annexed to the Union, causes will be
brought into operation which must inevitably remove slavery
from what may be called the farming States. From the best
information, it is no longer profitable to raise wheat, rye,
and corn, by slave labor. Where these articles are the only
staples of agricult
