"I told you it would come to that if you did not look sharp," answered Ned. "Take my advice now. A boy like you better begin with a trade and work up to be boss mechanic; then when you are rich, buy a library and turn scholar. There's a swell carpenter's school just started down at the Institute, box and tools included in the tuition, so you'll have some property at the end of the term, if you haven't ideas."

"I had thought of being a physicist, or chemist," replied Hal; "but carpentering is really more in my line; might try it at least. Suppose I talk it over at home."

"You better," said Ned, "than keep me out here bareheaded; good-by!"

"Much obliged and good-by," called out Hal, as he turned homewards.

It did not take long to obtain his parents' consent, as they hoped they saw in this definite wish an earnest of practical ability which would help them and him to decide the question of what he had better do. He had owned one or two carpenter's chests and had broken several tools, so that he knew something about their use which would count in the beginning.

Hal's pride suffered, however, when at the Institute he had to learn how to strike square blows, and to practise the wrist, elbow and shoulder movement, in striking with light tools. Then, too, he had to submit to be taught how to drive nails just so many inches apart, exactly as if he had never hammered before. He was as indignant, also, at being told to neither split nor cut towards himself, as if he had never hurt his jacket.

At last he was permitted to begin to make a picture frame. Its four sides had to be glued and dovetailed together, and the fitting required careful measurements. As Hal was too anxious to go ahead to attend to details, it is not surprising that the sides would not meet. The more he planed and chiselled, the worse it grew, till in despair he took it home for kindling wood.

Next he started on a bevelled-edge frame, and still despising exact measurements, he made the inner curve too deep, thus injuring the effect of his design.

Weary of mathematical carpentering, he turned to the ordinary, rough work of making a miniature house frame. His previous mistakes had helped him so much that here he soon went ahead of the other boys; but when he reached the staircase he began to fail. The steps were not alike in depth, nor were they placed at the right angles; he used up four blocks of wood, succeeding on the fifth, though the stairs were still rather steep.

His frame completed, he discovered that his acquaintances at the Institute had advanced to the turning-lathe. Too vexed and proud to go on and take up what they were leaving, he went into the moulding room. All went well at first; the frame was evenly placed, put together and inserted in the sand-box; but when he came back two days later and lifted the upper half, the sand all fell out and spoilt his mould; for he had paid very little attention to getting it into the completely proper condition for receiving an impression.
