The equilibrium maintained so carefully in the Senate had long since disappeared in the House because of the varying distribution of population. Of the 180 members who considered the Missouri question in the more popular branch, 104 came from the free States and only 76 from the slave States. The vote of 87 to 76 by which the House finally forbade slavery in the new State was indicative to some extent of this proportion, although party lines influenced a few votes. Virginia stood solidly for slavery, and New York, with one exception, against it. Of the nineteen votes from Pennsylvania, only one was cast for slavery in Missouri. Massachusetts was almost as unanimous. North and South Carolina, Georgia and Mississippi, the future champions of the system, unanimously opposed placing such restriction on the new State. The Senate, more nearly balanced, refused to agree with the restrictive vote of the House. A counter-measure was proposed by the Southern interests to admit Maine and Missouri jointly, allowing home rule to each on the slavery question. The majority in the House opposed this method of evidently opening the new State to slavery. A deadlock between the two branches was imminent. Meanwhile a bill had appeared in the Senate to draw the dividing-line between slavery and freedom across the Louisiana Purchase along thirty-six degrees and thirty minutes north latitude, a continuation of the Kentucky-Tennessee boundary. This would make Missouri a free State. Considering the triangular shape of the purchase, with the bulk of land lying to the north of the proposed line, the division was manifestly unequal. Roughly estimated, the proportions would be about one to seven. That would mean in time fourteen Northern and two Southern Senators. It would mean seven times the chances of population for representation in the House. At last, Henry Clay, Speaker of the House, who had favoured slavery in Missouri, was able to effect a compromise whereby thirty-six degrees and thirty minutes was accepted as the dividing-line; but the State of Missouri, which lay to the north of it, was made an exception and admitted without any restriction and, consequently, open to slavery. In all the remainder of the vast tract north of the line slavery was forbidden, as it had been in the Northwest Territory.
