This was the exciting and agitating question of the session of 1820-'21. The question of restriction, that is, of prescribing the abolition of slavery within her limits, had been "compromised" the session before, by agreeing to admit the State without restriction, and abolishing it in all the remainder of the province of Louisiana, north and west of the State of Missouri, and north of the parallel of 36 degrees, 30 minutes. This "compromise" was the work of the South, sustained by the united voice of Mr. Monroe's cabinet, the united voices of the Southern senators, and a majority of the Southern representatives. The unanimity of the cabinet has been shown, impliedly, by a letter of Mr. Monroe, and positively by the Diary of Mr. John Quincy Adams. The unanimity of the slave States in the Senate, where the measure originated, is shown by its journal, not on the motion to insert the section constituting the compromise (for on that motion the yeas and nays were not taken), but on the motion to strike it out, when they were taken, and showed 30 votes for the compromise, and 15 against it--every one of the latter from non-slaveholding States--the former comprehending every slave State vote present, and a few from the North. As the constitutionality of this compromise, and its binding force, have, in these latter times, begun to be disputed, it is well to give the list of the senators names voting for it, that it may be seen that they were men of judgment and weight, able to know what the constitution was, and not apt to violate it. They were Governor Barbour and Governor Pleasants, of Virginia; Mr. James Brown and Governor Henry Johnson, of Louisiana; Governor Edwards and Judge Jesse B. Thomas, of Illinois; Mr. Elliott and Mr. Walker, of Georgia; Mr. Gaillard, President, _pro tempore_, of the Senate and Judge William Smith, from South Carolina; Messrs. Horsey and Van Dyke, of Delaware; Colonel Richard M. Johnson and Judge Logan, from Kentucky; Mr. William R. King, since Vice-President of the United States, and Judge John W. Walker, from Alabama; Messrs. Leake and Thomas H. Williams, of Mississippi; Governor Edward Lloyd, and the great jurist and orator, William Pinkney, from Maryland; Mr. Macon and Governor Stokes, from North Carolina; Messrs. Walter Lowrie and Jonathan Roberts, from Pennsylvania; Mr. Noble and Judge Taylor, from Indiana; Mr. Palmer, from Vermont; Mr. Parrott, from New Hampshire. This was the vote of the Senate for the compromise. In the House, there was some division among Southern members; but the whole vote in favor of it was 134, to 42 in the negative--the latter comprising some Northern members, as the former did a majority of the Southern--among them one whose opinion had a weight never exceeded by that of any other American statesman, William Lowndes, of South Carolina. This array of names shows the Missouri compromise to have been a Southern measure, and the event put the seal upon
