When Mr. Calhoun saw that he could not bring the Senate to refuse formally to receive the Abolition petitions, he undertook to bring the Senate over to his views of the "States' sovereignty" character of the Union, of the obligation of the general Government to protect slavery in the slaveholding Commonwealths, of the ethical obligation of the people of the non-slaveholding Commonwealths not to attack the institution of slavery, and of the practical impotence of Congress to deal with slavery in the District of Columbia and in the Territories. He did not, however, succeed. The Senate did not repudiate his "States' sovereignty" view of the Union, but, while it was willing to say that neither the Northern Commonwealths nor the Northern people had any legal right to attack slavery under moral or religious pretexts, it would not say that they were under moral or religious obligations to abstain from the attack. Neither would the Senate say that the general Government must so exercise its powers as to give increased security to slavery, nor that the general Government had no power over the subject of slavery in the District and the Territories. It modified these demands of Mr. Calhoun so as to make them read, that the general Government should not so exercise its powers as to interfere with the security of the domestic institutions of the Commonwealths, and that the general Government ought not in good faith to undertake to abolish slavery in the District or in the Territories, except under certain conditions. {269} [Sidenote: The anti-slavery petition from the Vermont legislature.] The immediate occasion of the presentation of these resolutions of December 27th, 1837, by Mr. Calhoun, was probably the other incident to which reference has been made, the introduction, by Senator Swift, of Vermont, of a petition from the legislature of Vermont praying for the abolition of slavery in the District of Columbia. This shaft had struck Mr. Calhoun in his most vulnerable part. Here was, according to his own doctrine, a "sovereign State" instructing its governmental agent for general affairs. Could that agent refuse to receive the instructions of one of his principals? There certainly was no precedent for any such procedure as that in any system of jurisprudence known to the world. Mr. Calhoun recognized fully the embarrassment of his position. He begged that the communication from the Vermont legislature might lay upon the table until he could prepare his mind for action upon the subject, and pledged himself to call it up very shortly, if no one else should do so. Mr. Swift helped the Senate, and Mr. Calhoun especially, out of the dilemma by withdrawing the petition for the time being. This incident occurred on December 19th.
