This was only one of the many interests which he had plenty of time to follow, with the same sort of enthusiasm. At the age of fourteen, his laboratory was a thing of the past, but for all that, years after, at college, among his various other achievements, he had no trouble in winning a prize scholarship in chemistry. Another boy, brought up in a similar way and having learned to read without teaching, first took a lively interest in automobiles. When the family car went wrong, he watched the repairs, asked questions, and was ready to lend a helping hand. Many of the troubles on a modern car are apt to be in connection with the electrical equipment--battery, lights, magneto, timer, self-starter, etc. Sooner or later, a boy who takes an interest, is apt to become more or less familiar with the principle of all these things, especially if his nerves and brain are not deadened by forced application. At any rate, this boy soon did. This led to an interest in other electrical things--the ringing of bells and buzzers about the house, and the installation of an electric motor which would run the sewing machine, or a grindstone, or a little lathe. Then he got hold of a booklet about wireless telegraphy. There is something thrilling about the idea which appeals to the imagination--the receiving of mysterious messages from afar, through the air, and sending back from your little instrument the far-flying answers. At the age of twelve, this boy with the aid of a Japanese servant, had set up his own aerial and apparatus, had learned the code alphabet and was thoroughly familiar with all the delicate intricacies of detector, tuning coil, sparker and the rest of it. He had gotten in touch with certain other wireless operators within a radius of ten miles and, although he had never seen any of them, he could recognize instantly the sound of their different instruments and it was a joy and delight to hold conversations with them and call them up for a good-night, before he went to bed. And before he was thirteen, he undertook to construct with his own hands a tuning coil which would be better for his purposes than the kind he could afford to buy at the store. After much determined effort, he succeeded and installed it and had the satisfaction of finding that it was, indeed, decidedly better.
