sides yielded something. It was a law, passed on the 6th of March,
1820, providing that Missouri might come into the Union with slavery, but
that in all the remaining part of the territory purchased of France
which lies north of thirty-six degrees and thirty minutes north latitude,
slavery should never be permitted. This provision of law is the "Missouri
Compromise." In excluding slavery north of the line, the same language
is employed as in the Ordinance of 1787. It directly applied to Iowa,
Minnesota, and to the present bone of contention, Kansas and Nebraska.
Whether there should or should not be slavery south of that line, nothing
was said in the law. But Arkansas constituted the principal remaining
part south of the line; and it has since been admitted as a slave State,
without serious controversy. More recently, Iowa, north of the line, came
in as a free State without controversy. Still later, Minnesota, north
of the line, had a territorial organization without controversy. Texas,
principally south of the line, and west of Arkansas, though originally
within the purchase from France, had, in 1819, been traded off to Spain
in our treaty for the acquisition of Florida. It had thus become a part
of Mexico. Mexico revolutionized and became independent of Spain. American
citizens began settling rapidly with their slaves in the southern part
of Texas. Soon they revolutionized against Mexico, and established an
independent government of their own, adopting a constitution with slavery,
strongly resembling the constitutions of our slave States. By still
another rapid move, Texas, claiming a boundary much farther west than when
we parted with her in 1819, was brought back to the United States, and
admitted into the Union as a slave State. Then there was little or no
settlement in the northern part of Texas, a considerable portion of which
lay north of the Missouri line; and in the resolutions admitting her into
the Union, the Missouri restriction was expressly extended westward across
her territory. This was in 1845, only nine years ago.

Thus originated the Missouri Compromise; and thus has it been respected
down to 1845. And even four years later, in 1849, our distinguished
Senator, in a public address, held the following language in relation to
it:

"The Missouri Compromise has been in practical operation for about a
quarter of a century, and has received the sanction and approbation of men
of all parties in every section
