iven liberty in town had
never violated their trust. It seemed abominably mean and small to go
back on a man like this. He actually began to have his own doubts. But
it was very hard for Glen Mason to give up anything on which he had set
his heart.

There were several things went wrong which were quite disturbing. In the
first place he was obliged to change his clothing under the eye of the
physical director which utterly spoiled any scheme of hiding a suit of
overalls under his uniform. The walk to the street car and the ride to
the doctor's office would have been very enjoyable had not every one
stared at him and his uniform. More than once he heard some one say
"There goes a reform school boy." Then the dentist did all manner of
things in his efforts to find the nonexistent aching tooth. Finally he
did find an area of tenderness in an entirely different tooth to the one
specified.

"Does this tooth hurt you more than the others!" he asked.

"It does," Glen agreed, quite truthfully, an involuntary "Ouch"

"I thought as much," the doctor observed. "It is often hard to locate
the pain definitely. The nerve reflexes are responsible for it. I will
now drill into this and see what we find."

"Do you have to drill?" asked Glen.

"Surely. Have to clean out all the old decayed tooth before I fill it. I
often give the boys from the school a little sermon by telling them the

It did hurt but Glen would have fainted rather than make an outcry.

The doctor stepped to the 'phone and called up the superintendent.

"It's all right with the Mason boy," he said. "I've done all I can
to-day for him. I'm leaving now. What shall he do until time for his
car."

He turned to Glen as he received a reply.

"You are to wait until five o'clock in my reception room and then take
the inter-urban car," he said, locking the inner office when they passed
out. "I am leaving a little early to-night."

Before he left he stepped into a little closet which led out of the
reception room and changed his office clothes. Glen's eyes sparkled. His
problem was solved.

At five o'clock Glen Mason rode down in the elevator to the ground floor
and asked the elevator man how he could identify the inter-urban car.
But instead of leaving the building he dodged back to th
