Mr. GUTHRIE:--The committee did not require the assent of Virginia, because no part of the present District came from Virginia. We thought it unnecessary. Mr. DENT:--Maryland and Virginia originally joined in the cession of the District to the United States. Afterwards that portion which came from her was re-ceded to Virginia. But this question is not one of territory alone. The policy and interest of the two States are intimately connected. It would be far more satisfactory to both these States, and to the South, if the assent of Virginia was required before Congress could abolish slavery in the District. Still Maryland does not insist upon it. Mr. EWING:--I can see no necessity for, or propriety in, the amendment. We might as well require the consent of North Carolina or any of the other slave States. Virginia owns none of the District. She has no right to interfere. The amendment proposed by Mr. SEDDON was rejected by the following vote: AYES.--Maryland, Virginia, North Carolina, Tennessee, and Missouri--5. NOES.--Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Kentucky, Ohio, Indiana, Illinois, and Kansas--14. Mr. SEDDON:--My next proposition is to amend the third section by inserting after the words "landing in case of distress, shall exist," the words "and if the transportation be by sea, the right of property in the person held to service or labor shall be protected by the Federal Government as other property." We claim that our property in slaves shall be recognized by the Union just like any other property--that no unjust or improper distinction shall be made. When we trust it to the perils of the seas, we wish to have it protected by the Federal Government. Mr. WICKLIFFE:--I would inquire of the gentleman from Virginia whether it has not already been decided that this species of property is as much entitled to Federal protection as any other. I refer to the "Creole" case. The British Government made compensation for this species of property in that case. This was done upon the award of the commissioners pursuant to the decision of the umpire. Mr. SEDDON:--Yes! But on the express ground that slavery was recognized in the islands. Express notice was given, that when the emancipation policy was adopted, the same principles would not be recognized. We are now removing doubts. We wish to have these matters no longer involved in uncertainty. We insist upon having these provisions in the Constitution.
