Everybody knows the act of Congress of 1793, relative to the surrender of fugitive slaves, and the decision of the Supreme Court in the "Prigg case," 1842. But everybody does not know the bill of Mr. Webster's "friend at the head of the judiciary committee." There is a bill providing "for the more effectual execution of the third clause of the second section of the fourth article of the Constitution of the United States." It is as follows:-- _"Be it enacted by the Senate and House of Representatives of the United States of America, in Congress assembled_, That when a person held to service or labor, in any State or Territory of the United States, under the laws of such State or territory, shall escape into any other of the said States or territories, the person to whom such service or labor may be due, his or her agent, or attorney, is hereby empowered to seize or arrest such fugitive from service or labor, and to take him or her before any Judge of the Circuit or District Courts of the United States, or before any commissioner or clerk of such courts, or marshal thereof, or before any postmaster of the United States, or collector of the customs of the United States, residing or being within such State wherein such seizure or arrest shall be made; and, upon proof to the satisfaction of such judge, commissioner, clerk, postmaster, or collector, as the case may be, either by oral testimony or affidavit taken before and certified by any person authorized to administer an oath under the laws of the United States, or of any State, that the person so seized or arrested, under the laws of the State or territory, from which he or she fled, owes service or labor to the person claiming him or her, it shall be the duty of such judge, commissioner, clerk, marshal, postmaster, or collector, to give a certificate thereof to such claimant, his or her agent or attorney, which certificate shall be a sufficient warrant for taking and removing such fugitive from service or labor to the State or territory from which he or she fled.
