The fourth question of Mr. Lincoln is--Are you in favor of acquiring additional territory in disregard as to how such acquisition may affect the Union on the slavery question? This question is very ingeniously and cunningly put. The Black Republican crowd lays it down expressly that under no circumstances shall we acquire any more territory unless slavery is first prohibited in the country. I ask Mr. Lincoln whether he is in favor of that proposition? Are you opposed to the acquisition of any more territory, under any circumstances, unless slavery is prohibited in it? That he does not like to answer. When I ask him whether he stands up to that article in the platform of his party, he turns, Yankee fashion, and, without answering it, asks me whether I am in favor of acquiring territory without regard to how it may affect the Union on the slavery question. I answer that, whenever it becomes necessary, in our growth and progress, to acquire more territory, I am in favor of it without reference to the question of slavery, and when we have acquired it, I will leave the people free to do as they please, either to make it slave or free territory, as they prefer. It is idle to tell me or you that we have territory enough. * * * With our natural increase, growing with a rapidity unknown in any other part of the globe, with the tide of emigration that is fleeing from despotism in the old world to seek refuge in our own, there is a constant torrent pouring into this country that requires more land, more territory upon which to settle; and just as fast as our interest and our destiny require additional territory in the North, in the South, or in the islands of the ocean, I am for it, and, when we acquire it, will leave the people, according to the Nebraska bill, free to do as they please on the subject of slavery and every other question.
