But, gentlemen, it was not strange to the American people to know that there was danger of such a secession as has occurred. Some years ago it would have been esteemed the most impossible thing in the world. It has come to happen in your time and mine. It has been predicted. I know a very remarkable instance in which that prediction was stated so clearly that the author of it would seem to have been invested with the spirit and power of prophecy. We cherished the abiding hope that this would not occur; but we now see that the causes moving toward it were irresistible, and that it has become an event of history. Now, if these seceded States, on any reasoning, good or bad, on sufficient cause, or on a belief that they had sufficient cause, determined that it was not their interest to remain in the Union, they only subscribed to those doctrines promulgated by the Hartford Convention, and agreed with Blackstone, and with all the writers on civil law, that a state of things having happened in which they could have no redress, except by their own act, what course were they to adopt? It is not for you or for me to say, at this time, whether they were right or wrong in their opinions or reasons. I ask you, what course were they to adopt? and what has been the argument heretofore? Why, the argument that, when such a collision of interest took place--when the States supposed that the General Government was trespassing on them and usurping powers, making war upon their institutions, oppressing them, or failing to accomplish the ends for which the Government was established--they should appeal to the Supreme Court of the United States as common arbiter, and that its decision should be final. My friend, Mr. Larocque, has called attention to cases that might happen, of collision between executives of States and of the United States, which could not possibly be submitted to the decision of the Supreme Court of the United States, and I shall not mar his argument or his examples by repeating them or saying anything in addition.
