For the time it would seem that Mark Twain had given up authorship for business. The success of the Grant book had filled his head with plans for others of a like nature. The memoirs of General McClellan and General Sheridan were arranged for. Almost any war-book was considered a good venture. And there was another plan afoot. Pope Leo XIII., in his old age, had given sanction to the preparation of his memoirs, and it was to be published, with his blessing, by Webster & Co., of Hartford. It was generally believed that such a book would have a tremendous sale, and Colonel Sellers himself could not have piled the figures higher than did his creator in counting his prospective returns. Every Catholic in the world must have a copy of the Pope's book, and in America alone there were millions. Webster went to Rome to consult with the Pope in person, and was received in private audience. Mark Twain's publishing firm seemed on the top wave of success. The McClellan and Sheridan books were issued, and, in due time, the Life of Pope Leo XIII.--published simultaneously in six languages--issued from the press. A large advance sale had been guaranteed by the general canvassing agents--a fortunate thing, as it proved. For, strange as it may seem, the book did not prove a great success. It is hard to explain just why. Perhaps Catholics felt that there had been so many popes that the life of any particular one was no great matter. The book paid, but not largely. The McClellan and Sheridan books, likewise, were only partially successful. Perhaps the public was getting tired of war memoirs. Webster & Co. undertook books of a general sort--travel, fiction, poetry. Many of them did not pay. Their business from a march of triumph had become a battle. They undertook a "Library of American Literature," a work of many volumes, costly to make and even more so to sell. To float this venture they were obliged to borrow large sums. It seems unfortunate that Mark Twain should have been disturbed by these distracting things during what should have been his literary high-tide. As it was, his business interests and cares absorbed the energy that might otherwise have gone into books. He was not entirely idle. He did an occasional magazine article or story, and he began a book which he worked at from time to time the story of a Connecticut Yankee who suddenly finds himself back in the days of King Arthur's reign. Webster was eager to publish another book by his great literary partner, but the work on it went slowly. Then Webster broke down from two years of overwork, and the business management fell into other hands. Though still recognized as a great publishing-house, those within the firm of Charles L. Webster & Co. knew that its prospects were not bright.
