know more, Dick," said Jack. "You should not have
given them a clue like that."

"I won't say any more, then. They are within hearing and they will
understand, and you will see that they are careful how they talk
about you to any one after this."

"Let them talk," laughed Jack.

For two or three days things went on as usual in the camp on the river,
the boys doing a certain amount of study, drilling a little,
exercising in the outdoor gymnasium, skimming along the river in
their boats and otherwise occupying themselves, the time, on the
whole, passing very pleasantly.

Then one day a messenger came from a boys' camp some miles down the
river asking them to take part in a regatta, which was going to take
place at the other camp in a day or so.

"We know you Hilltop boys," said the messenger, "and we would like
to have some representatives of your Academy at our sports. Will
you send a few of them?"

The messenger had met Percival and Jack, and Percival now answered:

"We shall be very glad to send any number. Do you intend to have any

"You have a boy named Sheldon, who is a dandy at running a motor-boat,
haven't you?" the other boy asked.

"Yes, and he can get speed out of a canal-boat," laughed Dick.
"Do you want him?"

"We certainly do," said the other emphatically. "We have heard
of him, and we certainly want him."

"Here he is now. You can ask him yourself." The other boy was
a bit surprised at seeing the very boy he had been talking about,
and said:

"But I thought you were bigger. They said you were strong and wiry,
and I expected to see a giant. Why, you are no bigger than I am.
And you can run a motor-boat?"

"Certainly he can," replied Dick. "Size does not count in a thing
