use.

"Oh, it was splendid, Mamma!" cried her daughter. "Coming back in the
moonlight was just the nicest ever!"

"Did those grays behave themselves?" questioned Mr. Wadsworth, who was
present. "John said they acted rather frisky when he brought them
out."

"Oh, they were pretty frisky at first," returned Dave. "But I finally
managed to get them to calm down," he added. The matter had been
discussed by the young folks, and it had been decided not to say
anything about the runaway unless it was necessary.

On the following morning Dave had to apply himself diligently to his
studies. Since leaving Oak Hall he had been attending a civil
engineering class in the city with Roger, and had, in addition, been
taking private tutoring from a Mr. Ramsdell, a retired civil engineer
of considerable reputation, who, in years gone by, had been a college
friend of Dave's father. Dave was exceedingly anxious to make as good
a showing as possible at the coming examinations.

"Here are several letters for you, David," said old Mr. Potts to him
late that afternoon, as he entered the boy's study with the mail. "You
seem to be the lucky one," the retired professor continued, with a
smile. "All I've got is a bill."

"Maybe there is a bill here for me, Professor," returned Dave gaily,
as he took the missives handed out.

Dave glanced at the envelopes. By the handwritings he knew that one
letter was from Phil Lawrence and another from Shadow Hamilton, one of
his old Oak Hall chums, and a fellow who loved to tell stories. The
third communication was postmarked Coburntown, and in a corner of the
envelope had the imprint of Asa Dickley.

"Hello! I wonder what Mr. Dickley wants of me," Dave mused, as he
turned the letter over. Then he remembered how sour the store-keeper
had appeared when they had met the day before. "Maybe he wants to know
why I haven't bought anything from him lately."

Dave tore open the communication which was written on one of Asa
Dickley's letterheads. The letter ran as follows:

"MR. DAVID PORTER.

"DEAR SIR:

"I thought when I saw you in Coburntown to-day that you would come
in and see me; but you did not. Will you kindly let me know why
you do not settle up as promised? When I let you have the goods,
you said you would settle up by the end of the week without fail.
Unless you come in and settle up inside of the next week I shall
have to call the attention of your father to what you owe me.
