left exclusively to the disposal of the several States, without sanction or support from the National Government; and that the clause of the Constitution relative to persons held to service was one of compact between the States, and conferred no power of legislation on Congress, having been transferred from the ordinance of 1787, in which it conferred no power on the Confederation, and was never understood to confer any. He was subsequently engaged for the defence in the case of Driskell _vs._ Parish, before the U.S. Circuit Court at Columbus, and re-argued the same positions." Mr. Chase's _political_ history is thus summed up in the same article: "Mr. Chase's sentiments of hostility to the nationalization of slavery were expressed by his position in the political movements of the country, as well as his efforts at the bar. Prior to 1841 he had taken little part in politics. He had voted sometimes with the Democrats, but more commonly with the Whigs, who, in the North, seemed to him more favorable to anti-slavery views than their opponents. He supported Gen. Harrison in 1840, but the tone of his inaugural address, and still more the course of the Tyler administration, convinced him that no effective resistance to the encroachments of slavery was to be expected from any party with a slaveholding and pro-slavery wing, modifying if not controlling its action; and in 1841 he united in a call for a convention of the opponents of slavery and slavery extension, which assembled in Columbus in December of that year. This convention organized the liberty party of Ohio, nominated a candidate for governor, and issued an address to the people defining its principles and purposes.--This address, written and reported by Mr. Chase, and unanimously adopted by the convention, deserves attention as one of the earliest expositions of the political movements against slavery. In 1843, a national liberty convention assembled at Buffalo. Mr. Chase was an active member of the committee on resolutions, to which was referred, under a rule of the convention, a resolution proposing 'to regard and treat the third clause of the Constitution, whenever applied to the case of a fugitive slave, as utterly null and void, and consequently as forming no part of the Constitution of the United States, whenever we are called upon or sworn to support it.' Mr. Chase opposed the resolution, and the committee refused to report it. It was, however, afterward moved in the convention by its author, and adopted. Having been charged in the U.S. Senate with the authorship and advocacy of this resolution, by Mr. Butler of South Carolina, who denounced the doctrine of mental reservation apparently sanctioned by it, Mr. Chase replied: 'I have only to say I never proposed the resolution; I never would propose or vote for such a resolution. I hold no doctrine of mental reservation. Every man, in my judgment, should speak just as he thinks, keeping
