His face was thin, with a broad, good-humored mouth, a firm chin, a straight nose, and two very kindly brown eyes. Evan liked him from the very first moment of their meeting. And doubtless Evan’s sentiment was returned, otherwise Rob Langton would never have adopted him on such slight acquaintance, for Rob, while generally liked throughout Riverport School, had few close friends and was considered hard to know.

The two boys examined each other quite frankly while they talked, just as boys do. What Rob saw was a well-built, athletic-looking youngster, fairly tall, with a good breadth of shoulder, alert and capable. There was a pair of steady blue eyes, a good nose, a chin that, in spite of having a dimple in the middle of it, looked determined, and a well-formed mouth which, like Rob Langton’s, hinted of good humor. Evan’s hair, however, wasn’t in the least like that of the older boy. In the first place, it was several shades lighter, and, in the second place, it was very well-behaved hair and stayed where it was put. Even the folded towel which he wore around his forehead hadn’t rumpled it.

“I ought to be in the middle class,” Rob was explaining cheerfully. “When I came last year I expected to go into the junior, but Latin and Greek had me floored, and so, rather than make any unnecessary trouble for the faculty, I dropped into the preparatory. The fact is, Kingsford, I hate those old dead languages. Mathematics and I get on all right, and I don’t mind English, but Greek—well, I’d like to punch Xenophon’s head! Dad has it all cut out that I’m to be a lawyer; he’s one himself, and a good one; but if I can get my way I’m going to Cornell and go in for engineering. They call it structural engineering nowadays. That’s what I want to do, and there’s going to be a heap of trouble in our cozy little home if I don’t get my way. What are you going to be?”

“I don’t know—yet. I haven’t thought much about it. My father’s a doctor, but I don’t go in for that. I don’t like sick folks; besides, there doesn’t seem to be much money in doctoring.”

“Well, some of them seem to do pretty well,” replied Rob, thoughtfully. “You might be a specialist and charge big fees. When Dad was ill two years ago we had a fellow up from New York in consultation. He and our doctor got together in the library for about ten minutes, and then he ate a big lunch and went home again. And it cost Dad five hundred dollars.”

“That sounds all right,” laughed Evan, “but I guess he had to do a lot of hard work before he ever got where he could charge five hundred dollars.”

“I suppose so. Do you ever invent?”

“Invent? What do you mean?”

“Invent things, like—like this.” Rob began a search through his pockets and finally pulled out a piece of brass, queerly shaped and notched, some three inches long.
