The VIRGINIA Legislature assembled on the 2d of December. The Message of Governor FLOYD closes with some emphatic comments on the Compromise measures of Congress. The action of the last session on the subject, the Governor says, has placed the Union in the most momentous and difficult crisis through which it has ever passed. Some of its enactments have produced a feeling of deep and bitter dissatisfaction at the South; while the law for the recovery of fugitive slaves has been met with a reception at the North little, if at all, short of open rebellion and utter defiance. This state of things, the Governor says, has grown out of an "unwarrantable interference on the part of Congress with the subject of slavery, and is another proof of the great danger which must ever follow any attempt on the part of that body to transcend the clear, well-defined limits set by the Constitution to govern and control their action." The action of Congress, it is held, has been grossly injurious to the South, for of the whole domain acquired from Mexico, not a foot is left, worth having, for the occupation of the slaveholder. Nothing ought to reconcile the South to this action, but the hope that it may settle forever all agitation of the question of slavery. But if peace and quiet can be thereby restored, if the Constitution can be respected and the Union maintained, these sacrifices, great as they are, may well be regarded as light in comparison with the objects attained. But should this expectation prove fallacious, and the slavery agitation be renewed, it will furnish, the Governor says, "proof, convincing and conclusive, of that fixed and settled hostility to slavery on the part of the North which should and will satisfy every reasonable man that peace between us is impossible; and then a necessity stronger than all law, the necessity of self-preservation, will demand at our hands a separation from those who use the relationship of brotherhood only for the purpose of inflicting upon us the worst acts of malignant hostility." The supineness of the South upon this subject is very warmly censured, and the hostility evinced in the Northern States toward the fugitive slave law is referred to as among the indications that peace and harmony have not been restored. Virginia, and all the slaveholding states, he thinks, "can and ought, calmly and explicitly to declare that the repeal of the fugitive slave law, or any essential modification of it, is a virtual repeal of the Union. The faithful execution of the law is the only means now left by which the Union can be preserved with honor to ourselves and peace to the country. Such a declaration on the part of the South will give strength and great moral weight to the conservative patriots at the North, now struggling for the Constitution and the supremacy of the laws, who are, in truth, fighting the battle of the Union, in the bosom of the non-slaveholding States. If, however, no consideration of
