When Samuel was about nine years old his father decided to move to Hannibal, in the same State. The prime cause of this immigration was the failure of the elder Clemens to make Salt River navigable; hence, as one writer has suggested, the probable origin of the old synonym for disaster, "gone up Salt River."
Young Clemens was sent to school in Hannibal. Some of his schoolmates are living in the old town to-day. He seems to have enjoyed the rule of two teachers, Miss Newcomb and Miss Lucy Davis. Physically, he was not a strong boy, but intellectually he seems always to have been more than a match for any boy of his age. He had two brothers, Orion, who was considerably older, and Henry, who was the youngest of them all. Samuel attended school until his father died in 1847. The death of the father, who had just been elected county judge, was a hard blow to the family. After the death of his father, the subject of our sketch went to work for the local newspaper as a carrier. Afterward he served as "devil" and type-setter, and then, having completed his apprenticeship and thinking to better himself elsewhere, he set off on foot for the East. Doing odd jobs at the case and the press, he finally reached Philadelphia. Thence he went to New York. But the East did not please him, and at seventeen he was back in Hannibal.
He was now on his uppers, as the phrase is, and, in addition to its adventurous side, the financial side of steamboat life on the Mississippi magnetized him. There, for instance, was the pilot, the guide of the great smoking craft, a man who knew everything thought worth knowing, a man looked up to by every merchant, every traveler and every desperado. Samuel determined to become a pilot, and the picturesque Capt. Horace E. Bixby took him under his wing. In his "Life on the Mississippi" Mark Twain describes with all his eloquence the interesting and exciting life of a pilot on the treacherous river. And was not the pilot's a great and attractive post for a young man? "If you will take," says Mark, "the longest street in New York, and travel up and down it, conning its features patiently until you know every house and window and door and lamp-post and big and little sign by heart, and know them so accurately that you can instantly name the one you are abreast of when you are set down at random in that street in the middle of an inky-black night, you will then have a tolerable notion of the amount and the exactness of a pilot's knowledge who carries the Mississippi River in his head. And then if you will go on until you know every street-crossing, the character, size and position of the crossing-stones, and the varying depth of mud in each of those numberless places, you will have some idea of what the pilot must know in order to keep a Mississippi steamer out of trouble. Next, if you will take half of the signs on that long street and _change their places_ once a month, and still manage to know their new positions accurately on dark nights, and keep up with these repeated changes without making any mistakes, you will understand what is required of a pilot's peerless memory by the fickle Mississippi."
