There is little that fell from these two champions, as the fit was on, which deserves reply. Certainly not the hard words they used so readily and congenially. The veteran Senator from Virginia [Mr. MASON] complained that I had characterized one of his "constituents"--a person who went all the way from Virginia to Boston in pursuit of a slave--as Slave-Hunter. Sir, I choose to call things by their right names. White I call white, and black I call black. And where a person degrades himself to the work of chasing a fellow-man, who, under the inspiration of Freedom and the guidance of the North Star, has sought a freeman's home far away from coffle and chain,--that person, whosoever he may be, I call Slave-Hunter. If the Senator from Virginia, who professes nicety of speech, will give me any term more precisely describing such an individual, I will use it. Until then, I must continue to use the language which seems to me so apt. But this very sensibility of the veteran Senator at a just term, truly depicting an odious character, shows a shame which pleases me. It was said by a philosopher of Antiquity that a blush is the sign of virtue; and permit me to add, that, in this violent sensibility, I recognize a blush mantling the cheek of the honorable Senator, which even his plantation manners cannot conceal. And the venerable Senator from South Carolina, too, [Mr. BUTLER,]--he has betrayed his sensibility. Here let me say that this Senator knows well that I always listen with gurgles forth,--sometimes tinctured by generous ideas,--except when, forgetful of history, and in defiance of reason, he undertakes to defend what is obviously indefensible. This Senator was disturbed, when, to his inquiry, personally, pointedly, and vehemently addressed to me, whether I would join in returning a fellow-man to Slavery, I exclaimed: "Is thy servant a dog, that he should do this thing?" In fitful phrase, which seemed to come from unconscious excitement, so common with the Senator, he shot forth various cries about "dogs," and, among other things, asked if there was any "dog" in the Constitution? The Senator did not seem to bear in mind, through the heady currents of that moment, that, by the false interpretation he fastens upon the Constitution, he has helped to nurture there a whole kennel of Carolina bloodhounds, trained, with savage jaw and insatiable scent, for the hunt of flying bondmen. No, Sir, I do not believe that there is any "kennel of bloodhounds," or even any "dog," in the Constitution.
