on the train."

"I will deliver the book within fifteen minutes," Mr. Prescott
promised. "At the Gideon Wells place, did you say? I didn't
know that it had a tenant."

"Mrs. Carhart has taken the place for the summer. I will rely
upon you to deliver the book immediately. Thank you; good-bye."

"I suppose you have an appointment with the crowd, Dick," smiled
his father, as he hung up the receiver. "I don't like to get
in the way of your fun, but I shall have to ask you to deliver
the book, for the profit on that volume is too large to be overlooked."

"I don't mind going," Dick answered. "I can get back just a little
late. I'm all ready as soon as you have the book wrapped and
the bill made out."

Three or four minutes later Dick left the store. At the corner
of Main Street he looked to see whether any of his chums were
visible, but none were. So he turned and started, traveling fast.

Had young Prescott answered the 'phone call himself he very likely
would have suspected that the voice of the customer was that of
Bert Dodge disguised. However, as it was, the Grammar School
boy had no suspicion whatever. He made part of the distance at
a jog trot. He was soon in the less thickly inhabited part of
the town, down in a section of large estates, many of which were
used only as summer homes.

"This Mrs. Carhart must be a new-comer in Gridley," reflected
Dick, as he hastened along. "I hope she'll buy a lot of books
of us at as good prices."

He came now to the corner of the Wells estate, the grounds of
which were some eighty acres in extent. He passed the corner
and ran along toward two great elms that grew just inside the
trim wall.

Just as he reached these elms two figures started up from behind
the wall beyond. The same two figures leaped over the wall,
confronting the Grammar School boy.

"Howdy, Prescott," called Bert Dodge, with a mocking grin.

"We were just saying that we'd rather see you than any one else
on earth," leered Fred Ripley, as he stepped in the Grammar School
boy's path.

"I haven't any time to waste on you two just now," Prescott answered
coldly, trying to step around the pair.

"Then you'll take the time," scoffed Bert, reaching out to seize
Dick by the shoulder.

Fred Ripley aimed an unexpected blow that sent the lad to earth
and the book flying several feet beyond.
