MY DEAR ILES,--I got your other telegram a while ago, and answered it, explaining that I get only a couple of hours in the middle of the day for social life. I know it doesn't seem rational that a man should have to lie abed all day in order to be rested and equipped for talking an hour at night, and yet in my case and Cable's it is so. Unless I get a great deal of rest, a ghastly dulness settles down upon me on the platform, and turns my performance into work, and hard work, whereas it ought always to be pastime, recreation, solid enjoyment. Usually it is just this latter, but that is because I take my rest faithfully, and prepare myself to do my duty by my audience. I am the obliged and appreciative servant of my brethren of the Snow-shoe Club, and nothing in the world would delight me more than to come to their house without naming time or terms on my own part--but you see how it is. My cast iron duty is to my audience--it leaves me no liberty and no option. With kindest regards to the Club, and to you, I am Sincerely yours S. L. CLEMENS. In the next letter we reach the end of the Clemens-Cable venture and get a characteristic summing up of Mark Twain's general attitude toward the companion of his travels. It must be read only in the clear realization of Mark Twain's attitude toward orthodoxy, and his habit of humor. Cable was as rigidly orthodox as Mark Twain was revolutionary. The two were never anything but the best of friends. ***** To W. D. Howells, in Boston: PHILADA. Feb. 27, '85. MY DEAR HOWELLS,--To-night in Baltimore, to-morrow afternoon and night in Washington, and my four-months platform campaign is ended at last. It has been a curious experience. It has taught me that Cable's gifts of mind are greater and higher than I had suspected. But-- That “But” is pointing toward his religion. You will never, never know, never divine, guess, imagine, how loathsome a thing the Christian religion can be made until you come to know and study Cable daily and hourly. Mind you, I like him; he is pleasant company; I rage and swear at him sometimes, but we do not quarrel; we get along mighty happily together; but in him and his person I have learned to hate all religions. He has taught me to abhor and detest the Sabbath-day and hunt up new and troublesome ways to dishonor it. Nat Goodwin was on the train yesterday. He plays in Washington all the coming week. He is very anxious to get our Sellers play and play it under changed names. I said the only thing I could do would be to write to you. Well, I've done it. Ys Ever MARK.
