n't give it to me,"
answered Cohen, in a whining voice.

"Bowser, what's the meaning of this? What are you doing with Cohen's
slate?" demanded the doctor, frowning darkly.

Frank did not look a bit frightened, but still holding on to the slate,
which Cohen was making ineffectual efforts to regain, replied, in
respectful tones:

"May I hand you the slate first, sir?"

At these words Cohen turned ashy pale, and Dr. Johnston, realising that
there must be something going on that required explanation, ordered
Frank to bring all the slates up to him.

With radiant face Frank proceeded to obey, giving Bert a triumphant look
as he passed by him, while Cohen shrank back into his corner, and bit
his nails as though he would devour his finger tips. Taking up Cohen's
slate, the doctor scrutinised it carefully. One glance was sufficient. A
deep flush spread over his dark face, his eyes lighted up threateningly,
and in his sternest tones he called out:

"Cohen, come here!"

Amid the expectant hush of the school, none but class six knowing what
was the matter, Cohen, looking as though he would give his right hand to
be able to sink through the floor, walked slowly up into the dreadful
presence of the angered master. Holding up the slate before him, Dr.
Johnston asked:

"Is this your slate, sir?"

Cohen gave it a cowering glance, and said, faintly:

"Yes, sir."

"How long has this been going on?" thundered the doctor.

Cohen made no reply.

"Answer me, sir, at once. How long has this been going on?" repeated the
doctor.

"I don't quite know, sir; but not very long," faltered out Cohen.

With an exclamation of disgust, Dr. Johnston turned from him, and,
holding the slate up high so that all the school might see it, relieved
the curiosity of the scholars, now at fever pitch, by addressing them
thus:

"Cohen has just been detected in one of the most contemptible tricks
that has come under my observation since I have been master of this
school. He has evidently been committing to memory the answers to the
problems that would be given out, and instead of doing the work properly
has been scratching down a few figures, then writing the answers, and so
finishing long before any of the other scholars. I need hardly say that
this is not only a most contemptible trick, as I have already said, but
a serious blow at the principles of fair play and justice which should
regulate the winning of prizes in this school. I therefore
