In that speech he (Mr. L.) had simply expressed an expectation that "either the opponents of Slavery will arrest the further spread of it, and place it where the public mind shall rest in the belief that it is in the course of ultimate extinction, or its advocates will push it forward till it shall become alike lawful in all the States, old as well as new, North as well as South." Since then, at Chicago, he had also expressed a "wish to see the spread of Slavery arrested, and to see it placed where the public mind shall rest in the belief that it is in the course of ultimate extinction"--and, said he: "I said that, because I supposed, when the public mind shall rest in that belief, we shall have Peace on the Slavery question. I have believed--and now believe--the public mind did rest on that belief up to the introduction of the Nebraska Bill. Although I have ever been opposed to Slavery, so far I rested in the hope and belief that it was in the course of ultimate extinction. For that reason, it had been a minor question with me. I might have been mistaken; but I had believed, and now believe, that the whole public mind, that is, the mind of the great majority, had rested in that belief up to the Repeal of the Missouri Compromise. But upon that event, I became convinced that either I had been resting in a delusion, or the institution was being placed on a new basis--a basis for making it Perpetual, National, and Universal. Subsequent events have greatly confirmed me in that belief. "I believe that Bill to be the beginning of a Conspiracy for that purpose. So believing, I have since then considered that question a paramount one. So believing, I thought the public mind would never rest till the power of Congress to restrict the spread of it shall again be acknowledged and exercised on the one hand, or, on the other, all resistance be entirely crushed out. I have expressed that opinion and I entertain it to-night."
