Cable, meantime, having quite recovered, conceived a plan to repay Mark Twain's hospitality. It was to be an April-fool--a great complimentary joke. A few days before the first of the month he had a "private and confidential" circular letter printed, and mailed it to one hundred and fifty of Mark Twain's friends and admirers in Boston, New York, and elsewhere, asking that they send the humorist a letter to arrive April 1, requesting his autograph. It would seem that each one receiving this letter must have responded to it, for on the morning of April 1st an immense pile of letters was unloaded on Mark Twain's table. He did not know what to make of it, and Mrs. Clemens, who was party to the joke, slyly watched results. They were the most absurd requests for autographs ever written. He was fooled and mystified at first, then realizing the nature and magnitude of the joke, he entered into it fully-delighted, of course, for it was really a fine compliment. Some of the letters asked for autographs by the yard, some by the pound. Some commanded him to sit down and copy a few chapters from "The Innocents Abroad." Others asked that his autograph be attached to a check. John Hay requested that he copy a hymn, a few hundred lines of Young's "Night Thoughts," etc., and added: "I want my boy to form a taste for serious and elevated poetry, and it will add considerable commercial value to have it in your handwriting." Altogether, the reading of the letters gave Mark Twain a delightful day. The platform tour of Clemens and Cable that fall was a success. They had good houses, and the work of these two favorites read by the authors of it made a fascinating program. They continued their tour westward as far as Chicago and gave readings in Hannibal and Keokuk. Orion Clemens and his wife once more lived in Keokuk, and with them Jane Clemens, brisk and active for her eighty-one years. She had visited Hartford more than once and enjoyed "Sam's fine house," but she chose the West for home. Orion Clemens, honest, earnest, and industrious, had somehow missed success in life. The more prosperous brother, however, made an allowance ample for all. Mark Twain's mother attended the Keokuk reading. Later, at home, when her children asked her if she could still dance (she had been a great dancer in her youth), she rose, and in spite of her fourscore, tripped as lightly as a girl. It was the last time that Mark Twain would see her in full health.
