_A Tramp Abroad_ is a better book than _The Innocents Abroad_; it is quite as laughter-provoking, and its manner is far more restrained. Mark Twain was then master of his method, sure of himself, secure of his popularity; and he could do his best and spare no pains to be certain that it was his best. Perhaps there is a slight falling off in _Following the Equator_; a trace of fatigue, of weariness, of disenchantment. But the last book of travels has passages as broadly humorous as any of the first; and it proves the author’s possession of a pithy shrewdness not to be suspected from a perusal of its earliest predecessor. The first book was the work of a young fellow rejoicing in his own fun and resolved to make his readers laugh with him or at him; the latest book is the work of an older man, who has found that life is not all laughter, but whose eye is as clear as ever and whose tongue is as plain-spoken. These three books of travel are like all other books of travel in that they relate in the first person what the author went forth to see. Autobiographic also are _Roughing It_ and _Life on the Mississippi_, and they have always seemed to me better books than the more widely circulated travels. They are better because they are the result of a more intimate knowledge of the material dealt with. Every traveler is of necessity but a bird of passage; he is a mere carpetbagger; his acquaintance with the countries he visits is external only; and this acquaintanceship is made only when he is a full-grown man. But Mark Twain’s knowledge of the Mississippi was acquired in his youth; it was not purchased with a price; it was his birthright; and it was internal and complete. And his knowledge of the mining camp was achieved in early manhood when the mind is open and sensitive to every new impression. There is in both these books a fidelity to the inner truth, a certainty of touch, a sweep of vision, not to be found in the three books of travels. For my own part I have long thought that Mark Twain could securely rest his right to survive as an author on those opening chapters in _Life on the Mississippi_ in which he makes clear the difficulties, the seeming impossibilities, that fronted those who wished to learn the river. These chapters are bold and brilliant, and they picture for us forever a period and a set of conditions, singularly interesting and splendidly varied, that otherwise would have had to forego all adequate record.
