Undecided as to his plans, he was one day advised by a friend to deliver a lecture. He was already known as an entertaining talker, and his adviser judged his possibilities well. In Roughing It we find the story of that first lecture and its success. He followed it with other lectures up and down the Coast. He had added one more profession to his intellectual stock in trade.
Mark Twain, now provided with money, decided to pay a visit to his people. He set out for the East in December, 1866, via Panama, arriving in New York in January. A few days later he was with his mother, then living with his sister, in St. Louis. A little later he lectured in Keokuk, and in Hannibal, his old home.
It was about this time that the first great Mediterranean steamship excursion began to be exploited. No such ocean picnic had ever been planned before, and it created a good deal of interest East and West. Mark Twain heard of it and wanted to go. He wrote to friends on the 'Alta California,' of San Francisco, and the publishers of that paper had sufficient faith to advance the money for his passage, on the understanding that he was to contribute frequent letters, at twenty dollars apiece. It was a liberal offer, as rates went in those days, and a godsend in the fullest sense of the word to Mark Twain.
Clemens now hurried to New York in order to be there in good season for the sailing date, which was in June. In New York he met Frank Fuller, whom he had known as territorial Governor of Utah, an energetic and enthusiastic admirer of the Western humorist. Fuller immediately proposed that Clemens give a lecture in order to establish his reputation on the Atlantic coast. Clemens demurred, but Fuller insisted, and engaged Cooper Union for the occasion. Not many tickets were sold. Fuller, however, always ready for an emergency, sent out a flood of complimentaries to the school-teachers of New York and adjacent territory, and the house was crammed. It turned out to be a notable event. Mark Twain was at his best that night; the audience laughed until, as some of them declared when the lecture was over, they were too weak to leave their seats. His success as a lecturer was assured.
The Quaker City was the steamer selected for the great oriental tour. It sailed as advertised, June 8, 1867, and was absent five months, during which Mark Twain contributed regularly to the 'Alta-California', and wrote several letters for the New York Tribune. They were read and copied everywhere. They preached a new gospel in travel literature--a gospel of seeing with an overflowing honesty; a gospel of sincerity in according praise to whatever he considered genuine, and ridicule to the things believed to be shams. It was a gospel that Mark Twain continued to preach during his whole career. It became, in fact, his chief literary message to the world, a world ready for that message.
