When the measures were placed before President Monroe for his approval, he called a meeting of the Cabinet to consider the subject. There was no difficulty except upon a single point, the prohibition of slavery in the remainder of the Louisiana territory above thirty-six degrees and thirty minutes north latitude. Was this to be taken as prohibiting slavery in the Commonwealths which might be formed upon this territory in the future, or did the Congress only intend to lay this restriction upon this territory merely for the period during which it might continue subject to the exclusive jurisdiction of the general Government, the period of Territorial organization? If the former, the Missouri question would have to be fought over again whenever a new Commonwealth should be formed in this territory. The Cabinet interpreted the prohibition as applying only during the period before the Commonwealth organization should be established, and upon the basis of this interpretation advised the President that the measure was constitutional. The President signed the Maine bill on the 3rd of March and the Missouri bill on the 6th (1820). {90} [Sidenote: Review of the points involved in the contest.] So far as the questions of constitutional and parliamentary law were concerned, the settlement reached was in accordance with right principles. It was right that the two subjects, which the Senate united in one bill, should be separated. The only justification for this act of the Senate was the manifest determination on the part of the House to impose an unconstitutional restriction as the condition upon which the people of Missouri should be allowed to assume the status and the powers of a Commonwealth of the Union. It was the only weapon left to the more conservative Senate, by which to defend the Constitution against the rashness of the more radical House. It need astonish no impartial student of our history that the Senate used it. No such momentous question was involved in this point of parliamentary procedure as there was in the exaggerated interpretation of the powers of Congress by the House. The Senate showed its willingness to yield its position upon this point so soon as the House would return to sound constitutional principle in the Missouri question. It was fortunate for the development of the parliamentary practice of Congress that the House so changed its position in reference to the greater question of constitutional law as to enable the Senate to return to the true parliamentary principle of the separation of subjects which differ in essence or in circumstances in the slightest degree. While, therefore, the Senate should not be too strongly criticised for using its power over its own rules of procedure, as a means of retaliation, it is a matter of great satisfaction that expedients were at last found for maintaining right principle and sound parliamentary custom in the case. And it was surely right that
