John Clemens, Samuel's father, was a farmer, merchant, and postmaster in a Missouri town, called Florida. His wife, Jane Clemens, was a stirring, busy woman, who liked to get her work out of the way and then have a real frolic. Her husband did not know what it meant to frolic. He was not very well to begin with, and when he had any spare time, he sat by himself figuring away on an invention, year after year. He spent a good deal of time, too, thinking what fine things he would do for his family when he sold a great tract of land in Tennessee. He had bought seventy-five thousand acres of land when he was much younger, for just a few cents an acre, and when that land went up in price, he expected to be pointed out as a millionaire, at least. John Clemens was a good man and something of a scholar, but he was not the least bit merry. His children never saw him laugh once in his whole life! Think of it!
Mrs. Clemens did not like to have any one around when she was bustling through the housework, so the six children spent the days roaming through the country, picking nuts and berries. When it came night and they had had their supper, they would crowd around the open fire and coax Jennie, a slave girl, or Uncle Ned, a colored farm-hand, to tell them stories.
Uncle Ned was a famous story-teller. When he described witches and goblins, the children would look over their shoulders as if they half expected to see the queer creatures in the room. All these stories began "Once 'pon a time," but each one ended differently. One of the children, Sam Clemens, admired Uncle Ned's stories so that he could hardly wait for evening to come.
Sam was a delicate child. The neighbors used to shake their heads and declare he would never live to be a man, and every one always spoke of him as "little Sam."
When Mr. Clemens moved to another town some distance away, the mother said instantly: "Well, Hannibal may be all right for your business, but Florida agrees so well with little Sam, that I shall spend every summer here with the children, on the Quarles farm."
The children were glad she held to this plan, for Mr. Quarles laughed and joked with them, built them high swings, let them ride in ox-teams and go on horseback, and tumble in the hayfields all they wished. They had so much fun and exercise that they were even willing to go to bed without any stories. Sam grew plump.
A funny thing happened the first summer they went to nice Mr. Quarles's. Mrs. Clemens, with the older children, the new baby, and Jennie, went on ahead in a large wagon. Sam was asleep. Mr. Clemens was to wait until he woke up and then was to carry him on horseback, to join the rest. Well, as Mr. Clemens was waiting for Sam to finish his nap, he got to thinking of his invention, or his Tennessee land, and presently he saddled and bridled the horse and rode away without him. He never thought of Sam again until his wife said, as he reached the Quarles's dooryard: "Where is little Sam?"
"Why—why—" he stammered, "I must have forgotten him." Of course he was ashamed of himself and hurried a man off to Hannibal, on a swift horse, where Sam was found hungry and frightened, wandering through the locked house.
Sam was sent to school when he was five. He certainly did not like to study very well but did learn to be a fine reader and speller.
At the age of nine, Sam was a good swimmer (although he came very near being drowned three different times, while he was learning) and loved the river so that he was to be found on its shore almost any hour of the day. He longed to travel by steamer. Once he ran away and hid on board one until it was well down the river. As soon as he showed himself to the captain, he was put ashore, his father was sent for, and he received a whipping that he remembered a long time.
