This was a manly declaration in favor of extending slavery into the new territories, and in the only way in which it could be done—that is to say, by act of Congress. Mr. Clay met it by a declaration equally manly, and in conformity to the principles of his whole life, utterly refusing to plant slavery in any place where it did not previously exist. He answered:
"I am extremely sorry to hear the senator from Mississippi say that he requires, first, the extension of the Missouri compromise line to the Pacific, and also that he is not satisfied with that, but requires, if I understood him correctly, a positive provision for the admission of slavery south of that line. And now, sir, coming from a slave State, as I do, I owe it to myself, I owe it to truth, I owe it to the subject, to say that no earthly power could induce me to vote for a specific measure for the introduction of slavery where it had not before existed, either south or north of that line. Coming as I do from a slave State, it is my solemn, deliberate and well matured determination that no power, no earthly power, shall compel me to vote for the positive introduction of slavery either south or north of that line. Sir, while you reproach, and justly too, our British ancestors for the introduction of this institution upon the continent of America, I am, for one, unwilling that the posterity of the present inhabitants of California and of New Mexico shall reproach us for doing just what we reproach Great Britain for doing to us. If the citizens of those territories choose to establish slavery, and if they come here with constitutions establishing slavery, I am for admitting them with such provisions in their constitutions; but then it will be their own work, and not ours, and their posterity will have to reproach them, and not us, for forming constitutions allowing the institution of slavery to exist among them. These are my views, sir, and I choose to express them; and I care not how extensively or universally they are known."
These were manly sentiments, courageously expressed, and taking the right ground so much overlooked, or perverted by others. The Missouri compromise line, extending to New Mexico and California, though astronomically the same with that in Louisiana, was politically directly the opposite. One went through a territory all slave, and made one-half free; the other would go through territory all free, and make one-half slave. Mr. Clay saw this difference, and acted upon it, and declared his sentiments honestly and boldly; and none but the ignorant or unjust could reproach him with inconsistency in maintaining the line in the ancient Louisiana, where the whole province came to us with slavery, and refusing it in the new territories where all came to us free.
Mr. Seward, of New York, proposed the renewal of the Wilmot proviso:
"Neither slavery nor involuntary servitude, otherwise than by conviction for crime, shall ever be allowed in either of said territories of Utah and New Mexico."
