A story is told of how Robert came into school late one morning and gave as his excuse that he had been at a shop beating a piece of lead into a pencil. At the same time he took the pencil from his pocket, and showing it to his teacher, said: "It is the best one I have ever used." Upon carefully looking at the pencil, the schoolmaster was so well pleased that he praised Robert's efforts, and in a short time nearly all the pupils were using that kind of pencil. [Illustration: Fulton's First Experiment with Paddle-Wheels.] Another example of Robert's inventive gift belongs to his boyhood days. He and one of his playmates from time to time went fishing in a flatboat, which they propelled with long poles. It was hard work and slow, and presently Robert thought out an easier way. He made two crude paddle-wheels, attached one to each side of the boat, and connected them with a sort of double crank. By turning this, the boys made the wheels revolve, and these carried the boat through the water easily. We may be sure that Robert's boat became very popular, and that turning the crank was a privilege in which each boy eagerly took his turn. While still young, Robert began to paint pictures also. By the time he was seventeen he had become skilful in the use of his brush and went to Philadelphia to devote his time to painting portraits and miniatures. Being a tireless worker, he earned enough here to support himself and send something to his mother. At the age of twenty-one his interest in art led him to go to London, where he studied for several years under Benjamin West. This famous master took young Fulton into his household and was very friendly to him. After leaving West's studio Fulton still remained in England, and although continuing to paint he gave much thought also to the development of canal systems. His love for invention was getting the better of his love for art and was leading him on to the work which made him famous. He was about thirty when he finally gave up painting altogether and turned his whole attention to inventing. He went from England to Paris, where he lived in the family of Joel Barlow, an American poet and public man. Here he made successful experiments with a diving boat which he had designed to carry cases of gunpowder under water. This was one of the stages in the development of our modern torpedo-boat. Although this invention alone would give Fulton a place in history, it was not one which would affect so many people as the later one, the steamboat, with which his name is more often associated. Even before he had begun to experiment with the torpedo-boat Fulton had been deeply interested in steam navigation, and while in Paris he constructed a steamboat. In this undertaking he was greatly aided by Robert R. Livingston, American minister at the French court, who had himself done some experimenting in that line. Livingston, therefore, was glad to furnish the money which Fulton needed in order to build the boat.
