Major Pond, by the way, relates that Mark Twain committed his lecture to memory and was entirely confident of success; still, desiring to forestall even the possibility of failure, he arranged with some friend of his--Major Pond has forgotten her name--to sit in a box and start the applause if he should look in her direction and stroke his mustache. "Instead of failing, however," the Major reports, "the lecture started propitiously, and that caused Mark to forget his instructions to the lady. By and by, unconsciously, when the audience was filled to the neck with pleasure and sore with laughter, he unwittingly turned to the box where his friend sat and pulled his mustache. At the time he was saying nothing particularly good or funny, but the anxious lady took his action for the signal, and almost broke her fan on the edge of the box in a fury of applause." It took all the nerve which Mark had accumulated among the gamblers and crevasses of the Mississippi to pass through the embarrassment. In 1867 Mr. Clemens published his first book, "The Jumping Frog of Calaveras County, and Other Sketches," of which about four thousand copies were sold. That same year he went to Europe with the excursionists aboard the Quaker City. This excursion proved to be the turning point in his career. He had a commission to write sketches of the journey for the _Alta Californian_. The sketches were duly published, and were then collected and offered to a publisher for marketing in book form. The material did not appeal to the publisher; it was startlingly uncut and undried. But Mark was insistent, and by and by the book appeared under the title of "Innocents Abroad." That book established Mark Twain's reputation as a humorist. During the thirty-three years which have intervened between that day and the present, Mark Twain's reputation has been maintained at a matchless height. No one has been deemed worthy by the reading public--which, after all, is the Supreme Court in literary matters--to be called his rival. And since the publication of "Innocents Abroad" Mark Twain's career has been public property, with no signs, no fences, not even a dog therein to bark at night. Mark Twain's career stands unequalled in the literary history of America. He has been honored as an author and as a lecturer in almost every part of the world. He made a fortune and lost it; and now he is making another. The literary historian must record in his case the prodigious achievement of an author remaining for at least thirty-three years--and who knows how many more will follow?--in almost steady demand in print and on the platform.
