"That is because you have never learned to use tools properly," said his father. "Where do you suppose I'd be now if I hadn't started out when I was a boy to tinker round a farm? That's where I got my manual training, and there isn't a course in the country that can equal it. I had to use my brains, too, as well as my hands, for very often the things I needed were not to be had and I was forced to make something else do. It was a great education, I can tell you! What skill I have at surgery I attribute largely to that early training. Now we'll set right to work to remedy this lack in you, son. I'll see your principal to-day and arrange for you to begin sloyd when you go back to school." Theo made a grimace at which his father laughed. "If you don't like it you can at least take it as a medicine," remarked the Doctor with a grin. Dr. Swift was as good as his word, for when Theo returned to school the following day he found that in addition to his other work he was expected to spend an hour each morning in the carpenter's shop, a realm toward which he had always maintained the keenest scorn. It seemed such a foolish thing to learn to saw and drive nails! What was the use of taking lessons? When a board was to be cut what was there to do but take the saw and cut it? It was easy enough. As for driving nails--that feat required no teaching. But to Theo's amazement it needed only the first lesson to demonstrate to him that these superficial conclusions were quite wrong. It was one thing to cut a board haphazard; but quite another matter to cut it evenly, and on a ruled line. Nor was the driving of nails as simple as he had supposed. At the end of the first hour Theo, feeling very awkward and clumsy, and rubbing a finger that had been too slow to get out of the path of the hammer, left the workshop. "I never dreamed it would be so hard!" he muttered, viewing his bleeding knuckle with chagrin. The lesson of the following day did not prove much easier, and its difficulties aroused the lad's fighting spirit. "I am going to learn to saw and drive nails properly if it takes me the rest of my life!" he declared resolutely. "The very idea! Why, some of those little chaps in the sloyd room can chisel and plane like carpenters. I'll bet I can do it, too, if I stick at it."
