The boy jumped from his seat in his excitement. "I'd like it very much, sir. Do you mean to tell the men what to do, and to have real tools to work with?" Count Platen smiled. "Yes, to have entire charge of a part of the work. That's what I mean. I really think you could do it. How old are you, John?" "I'll be fourteen very soon." "Hm," mused the Count, "It seems absurd to put a boy of fourteen in charge of six hundred soldiers. And yet if he has the skill to do the work, why not? And there's small doubt that he has. Well, John, I'll see what can be done. Meet me here to-morrow morning." The next day Count Platen found John anxiously awaiting him. He told the boy at once that his plan had proved successful, and that both John and Nils were to be enrolled as cadets in the mechanical corps of the Swedish navy, and that John was to be put in charge of part of the canal building. The boy was highly delighted; he knew that now he should have a chance to try in actual working some of the inventions he had planned on paper. As soon as he had thanked his kind friend the Count he ran home to tell his mother the news of Nils' and his good fortune. It was a curious sight when the officer in command of the troops placed six hundred soldiers in charge of young John Ericsson. They were too well trained to laugh, but they were tremendously surprised when they saw that their future orders were to come from this small, curly-haired lad just barely turned fourteen. Olof Ericsson himself was scarcely less surprised than the men; he knew his son's great mechanical ability, but he could hardly believe that others had come to realize it so soon. A few days of actual work on the canal, however proved that Count Platen had made no mistake. John knew what ought to be done, and he could show the soldiers new and better ways of getting results, although he was actually too small to reach the eyepiece of his leveling instrument without the aid of a camp-stool which he carried about with him. He brought out some of the mechanical drawings he had worked over, and had machinery made after them, and whenever his inventions were tried they met with success. For several years John commanded his six hundred men at the Goeta Canal, and then he decided to enter the army. He had grown tall, and was noted for his great strength and skill in feats of arms. At seventeen he was made an Ensign in the Rifle Corps, and soon after Lieutenant in the Royal Chasseurs. He was fond of the life of the army, but he saw there was no great future in it for him, and he could not give up his passion for science and invention. He procured an appointment as surveyor for the district of Jemtland, and found himself free again to work on his own lines.
