B. Werner, Caseyville, January 4, refers to a former letter enclosing a petition for the establishment of a post-office at Caseyville. Hearing nothing of the matter, he went to see Mr. Armstrong, the postmaster at St. Louis, narrated the facts, and asked whether any order had been received by him respecting it. "He asked me to whom I had sent the petition. I told him to you. He replied if I had sent the petition to Robert Smith (Dem. M.C.) the matter would have been attended to, but as Mr. Trumbull was a Black Republican, the department would not pay any attention to it." On the 2d of February, 1858, President Buchanan sent a special message to Congress with a copy of the Lecompton Constitution, and recommended that Kansas be admitted to the Union as a state under it. In this message he made reference to the Dred Scott decision, which had been pronounced by the Supreme Court in the previous March. On this point the message said: It has been solemnly adjudged by the highest tribunal known to our laws that slavery exists in Kansas by virtue of the Constitution of the United States. Kansas is, therefore, at this moment as much a slave state as Georgia, or South Carolina. Trumbull made a speech on the special message as soon as the reading of it was finished by the secretary. He reviewed the action of Governor Walker, which, in the beginning, had been avowedly taken with the view of creating and promoting a Free State Democratic party in Kansas, to which end he had made use of the soldiers placed at his disposal by the President. That this was an act of usurpation was conclusively shown by Trumbull, although Walker claimed that it had served the desirable purpose of preventing an armed collision between the contending factions. Trumbull then touched upon the Dred Scott case and maintained that the Supreme Court had likewise usurped authority by pronouncing an opinion on a case not before it. The court had virtually dismissed the case for want of jurisdiction. It had decided that Dred Scott was not a citizen and had no right to bring this action. There was no longer any case before the judges who so held. "Their opinions," said Trumbull, "are worth just as much as, and no more than, the opinions of any other gentlemen equally respectable in the country." Consequently, President Buchanan's assertion that Kansas was then as much a slave state as Georgia or South Carolina was unfounded and preposterous. Seward, Fessenden, and the Republican Senators generally held to this doctrine, but Senator Benjamin, of Louisiana, replied with considerable force that it was competent for the court to decide on what grounds it would give its decision, and that it did, in so many words, elect to decide the question of slavery in the territories, which was the principal question raised by the counsel of Dred Scott. That the decision had an aim
