who had a lame foot. A
doctor cured his foot, and some time after, the patient brought another
lame dog to the doctor, and showed by signs that he wanted this other
dog cured, too."

"That's rather a good dog-story," said Susan. "But what made you think
of it?"

"Because I'm that first dog."

"You are?"

"Yes. You've helped me, but there's Bob Holliday. I've been helping him,
but he's got to a place where I don't quite understand the thing myself.
Now Bob wouldn't dare ask you to help him----"

"Bring him along. How the Greenbank Academy grows!" laughed Susan,
turning to her father.

Bob was afraid of Susan at first--his large fingers trembled so much
that he had trouble to use his slate-pencil. But by the third evening
his shyness had worn off, so that he got on well.

One evening, after a week of attendance, he was missing. The next
morning he came to Jack's house with his face scratched and his eye
bruised.

"What's the matter?" asked Jack.

"Well, you see, yesterday I was at the school-house at noon, and Pewee,
egged on by Riley, said something he oughtn't to, about Susan, and I
couldn't stand there and hear that girl made fun of, and so I up and
downed him, and made him take it back. I can't go till my face looks
better, you know, for I wouldn't want her to know anything about it."

But the professor heard all about it from Joanna, who had it from one of
the school-boys. Susan sent Columbus to tell Bob that she knew all about
it, and that he must come back to school.

"So you've been fighting, have you?" she said, severely, when Bob
appeared. The poor fellow was glad she took that tone--if she had
thanked him he wouldn't have been able to reply.

"Yes."

"Well, don't you do it any more. It's very wrong to fight. It
makes boys brutal. A girl with ability enough to teach the Greenbank
Academy can take care of herself, and she doesn't want her scholars to
fight."

"All right," said Bob. "But," he muttered, "I'll thrash him all the
same, and more than ever, if he ever says anything like that again."

CHAPTER XIV

CROWING AFTER VICTORY

Greenbank was awake, and the old master had to go. Mr. Weathervane stood
up for him as long as he thought that the excitement was temporary. But
when he found that Greenbank really was awake, and not just talking in
its sleep, as it did for the most part, he changed sides,--not all at
once, but by degrees. At first he softened down a little, "hemmed and
