I answered, as I thought, in this way: that I am not generally opposed to the acquisition of additional territory, and that I would support a proposition for the acquisition of additional territory according as my supporting it was or was not calculated to aggravate this slavery question amongst us. I then proposed to Judge Douglas another interrogatory, which was correlative to that: "Are you in favor of acquiring additional territory, in disregard of how it may affect us upon the slavery question?" Judge Douglas answered,--that is, in his own way he answered it. I believe that, although he took a good many words to answer it, it was a little more fully answered than any other. The substance of his answer was that this country would continue to expand; that it would need additional territory; that it was as absurd to suppose that we could continue upon our present territory, enlarging in population as we are, as it would be to hoop a boy twelve years of age, and expect him to grow to man's size without bursting the hoops. I believe it was something like that. Consequently, he was in favor of the acquisition of further territory as fast as we might need it, in disregard of how it might affect the slavery question. I do not say this as giving his exact language, but he said so substantially; and he would leave the question of slavery, where the territory was acquired, to be settled by the people of the acquired territory. ["That's the doctrine."] May be it is; let us consider that for a while. This will probably, in the run of things, become one of the concrete manifestations of this slavery question. If Judge Douglas's policy upon this question succeeds, and gets fairly settled down, until all opposition is crushed out, the next thing will be a grab for the territory of poor Mexico, an invasion of the rich lands of South America, then the adjoining islands will follow, each one of which promises additional slave-fields. And this question is to be left to the people of those countries for settlement. When we get Mexico, I don't know whether the Judge will be in favor of the Mexican people that we get with it settling that question for themselves and all others; because we know the Judge has a great horror for mongrels, and I understand that the people of Mexico are most decidedly a race of mongrels. I understand that there is not more than one person there out of eight who is pure white, and I suppose from the Judge's previous declaration that when we get Mexico, or any considerable portion of it, that he will be in favor of these mongrels settling the question, which would bring him somewhat into collision with his horror of an inferior race.
