It has been said that Mark Twain first met Olivia Langdon on the "Quaker City," but this is not quite true; he met only her picture--the original was not on that ship. Charlie Langdon, boy fashion, made a sort of hero of the brilliant man called Mark Twain, and one day in the Bay of Smyrna invited him to his cabin and exhibited his treasures, among them a dainty miniature of a sister at home, Olivia, a sweet, delicate creature whom the boy worshiped. Samuel Clemens gazed long at the exquisite portrait and spoke of it reverently, for in the sweet face he seemed to find something spiritual. Often after that he came to young Langdon's cabin to look at the pictured countenance, in his heart dreaming of a day when he might learn to know its owner. We need not follow in detail here the travels of the "pilgrims" and their adventures. Most of them have been fully set down in "The Innocents Abroad," and with not much elaboration, for plenty of amusing things were happening on a trip of that kind, and Mark Twain's old note-books are full of the real incidents that we find changed but little in the book. If the adventures of Jack, Dan, and the Doctor are embroidered here and there, the truth is always there, too. Yet the old note-books have a very intimate interest of their own. It is curious to be looking through them to-day, trying to realize that those penciled memoranda were the fresh first impressions that would presently grow into the world's most delightful book of travel; that they were set down in the very midst of that historic little company that frolicked through Italy and climbed wearily the arid Syrian hills. It required five months for the "Quaker City" to make the circuit of the Mediterranean and return to New York. Mark Twain in that time contributed fifty two or three letters to the "Alta California" and six to the "New York Tribune," or an average of nearly three a week--a vast amount of labor to be done in the midst of sight-seeing. And what letters of travel they were! The most remarkable that had been written up to that time. Vivid, fearless, full of fresh color, humor, poetry, they came as a revelation to a public weary of the tiresome descriptive drivel of that day. They preached a new gospel in travel literature--the gospel of seeing honestly and speaking frankly--a gospel that Mark Twain would continue to preach during the rest of his career.
