The formal vote connecting the two subjects of Maine and Missouri was taken in the Senate on February 16th, and after this was resolved upon, Mr. Thomas immediately renewed his motion to amend the bill by the addition of a clause prohibiting slavery in the Louisiana territory above thirty-six degrees and thirty minutes, outside of the boundaries of the proposed Commonwealth of Missouri. After an attempt, on the one side, to carry this line up to the fortieth parallel, and a counter attempt on the other to make the prohibition extend to all the territory west of the Mississippi, except that already under Commonwealth government, or in process of being put under Commonwealth government by the existing bill—the result of which would have been the prohibition of slavery in the just organized Territory of Arkansas—Mr. Thomas' amendment was adopted as the fair compromise. The bill, as thus amended, passed the Senate on February 18th, 1820, and was sent immediately to the House of Representatives.
| The House of Representatives' refusal to agree to the combination. The conference on the subject, and the first Missouri compromise. |
The form of the bill was now the House bill in regard to Maine, with the Missouri bill and the Thomas proposition attached to it as amendments. The House voted to disagree to these amendments, and sent the bill, stripped of them, back to the Senate. The Senate voted immediately to insist upon its amendments, and the House answered with a vote insisting upon its position. Thereupon, the Senate requested a conference with the House upon the subject, and appointed Mr. Pinkney, Mr. Barbour, and Mr. Thomas as its representatives. The House acceded to the request and appointed Mr. Holmes, Mr. Taylor, Mr. Lowndes, Mr. Parker, and Mr. Kinsey as its representatives. These gentlemen met and agreed without much difficulty to the following points: That the Senate should withdraw its amendments to the House bill for the admission of Maine; that both the Senate and the House should pass the Missouri bill, without the condition in reference to the restriction of slavery in the proposed Commonwealth; and that both the Senate and the House should add a provision to the Missouri bill prohibiting slavery in the remainder of the Louisiana territory north of thirty-six degrees and thirty minutes. That is, the House should gain its point of order in the separation of the two subjects; the Senate should gain its point of constitutional law in defending the new Commonwealth against restrictions not imposed by the Constitution upon the original Commonwealths; and the two should compromise upon a fair division of the remaining parts of the Louisiana territory between the interests of the North and those of the South. The Senate accepted the recommendations of the committee without much difficulty, and voted the measures contained in them. The House also accepted the recommendations and voted the necessary provisions upon its part.
| President Monroe's approval of the Compromise. |
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).
