The boys rowed up alongside and holding to the gunwale of the "Red Rover," chatted for a few moments.
"So long! We will see you in the morning," called George as they pushed the rowboat off.
"Yes.

In the morning--maybe," answered Harriet laughingly.
"It's my opinion that those girls are going to try to play more tricks to-night," declared Billy, after they had gotten a short distance from the "Red Rover." He was speaking in a tone louder than he imagined.
Harriet heard every word he said.
"Yes," agreed George.

"I'll tell you what we'll do.

We'll put a boy on watch to-night.

Then, if they try to run away from us, we will just follow and give them a surprise.
