and the face of each turned pale.

"Wha--what do you want, Porter?" stammered Merwell.

"Ah, don't talk to him," blustered Jasniff. "Let go of me!" And he tore
himself loose.

"Jasniff, you've got to talk to me," answered Dave. "If you won't talk
I'll call an officer."

"Don't you do that!" cried Merwell, in increased alarm. "You let me go!
It's a--a--mistake! I haven't done anything!" And he commenced to back
towards the door.

"Merwell, you and Jasniff played me a dirty trick!" declared Dave. "I
don't know whether to have you arrested or to take it out of you. I gave
you a sound thrashing once, but it doesn't seem to have done you much
good."

"You--you let me alone, Porter!"

"Where are you going?" asked Roger.

"Don't you tell them!" burst out Jasniff, quickly. "It's none of their
business!" And he looked knowingly at Merwell.

"I guess I had better call an officer," suggested Phil, just by way of
intimidating the rascally students.

"No--no--don't do it!" cried Link Merwell. "Come on, Nick, there is the

He leaped past the others, and out of a back door of the station. As

"No. What's the use?"

"Where is Jasniff?" asked Roger.

"There he goes!" cried Dave, and pointed to the end of the train, which
the student named had just boarded.

The train was now moving, and as it swept by, the three lads on the
platform saw Link Merwell peer anxiously out of a window at them. Then,
as the last car rolled by, they beheld Nick Jasniff in the doorway. He
shook his fist at them.

"Just wait, Dave Porter!" he yelled, defiantly. "Just wait, that's all!"
And then the train disappeared swiftly from view.

"Wonder if they are running away from the academy?" came from Phil.

"It looks like it to me," answered Dave. "I guess they are pretty badly
scared. Maybe they know that Doctor Montgomery had turned against them."

"Well, if they only stay away it won't be so bad," said the senator's
son.

"I might telegraph ahead and have them held," said Dave. "But I guess it
isn't worth while."

"Do you know what I think?" said Phil. "I think they were at that Mrs.
Slater's house the night we called, and what we said scar
