He was such a wide-awake, good-natured lad that the trainmen liked him. He found that he had a good deal of time to spare; so he got some old type from a printer and, in a corner of the baggage car, began to print a four-page newspaper about the size of a small handkerchief, which he named _The Grand Trunk Herald_. The trainmen and their families and friends liked this young Edison’s news. Soon he had about five hundred subscribers, so he made about ten dollars a week from his little paper. Meanwhile he attended strictly to business. During the Civil War he would find out when there had been a battle and have the telegraph operator send word of the event ahead of the train to the towns where the trains would stop. This brought hundreds of people down to the stations at [Illustration: THOMAS A. EDISON AND ONE OF HIS EARLY DYNAMOS.] train-time to learn the news of the battle. Young Edison would sell hundreds--once he sold a thousand--newspapers at ten to twenty-five cents apiece. He was always trying to do something new. After his little paper became well known, he began to buy chemicals and keep them in bottles in his printing office in the car. One day the phosphorus jar fell off the shelf and broke. This set fire to the floor of the car. While Alva was putting out the fire the conductor came through. It made him so angry to have a boy around who might burn up the train with his experiments, that he threw out bottles, printing-press, and type, and pushed the boy after them. Alva did not hold a grudge against that conductor. He only wondered that the trainmen had stood that sort of thing so long. He saved all he could out of the ruins and set up his printing plant in the cellar of his father’s house. He went back to work as though nothing had happened, and attended only to selling papers. One day while waiting on the platform of a station he saw the station agent’s child on the tracks and an express train coming. Throwing down his newspapers he jumped, seized the child, and sprang across the track just in time to save its life and his own. The station man wept as he seized the heroic newsboy’s hand. “I am a poor man,” he said, “so I can’t repay you for saving my child’s life; but I can teach you telegraphy.” Edison was delighted. He stopped at that station several times a week and learned very soon to send and receive messages. It is harder to take than to send telegraph dispatches. Young Edison invented a machine which would run more slowly than the telegraph and which gave him time to write out the words while the “dots and dashes” of the telegraph alphabet were clicking away. But sometimes it is impossible to attach this appliance; so young Edison practised till he could receive the fastest news story.
