"And Mr. Porter and Mr. Morr!" added Vera Rockwell.

"Please stop the boat, we want to speak to them," went on Mary, to Merwell.

"Can't stop just now," grumbled the bully, as he tried to make the engine run still faster.

"Why, the idea!" exclaimed the strange girl of the party. "I thought you could stop a motor boat any time."

"So you can," added Vera Rockwell. "I want you to stop," she went on, commandingly.

"Can't do it," answered Merwell, and then he winked at Poole, who had turned his head to listen to the talk.

"Well, I think you are real mean!" pouted Mary. "I shall never ask you to take me across the river again. You've kept us on the motor boat now nearly an hour!"

"If you don't land us where we want to go, and as soon as possible, I'll tell my brother," said Vera.

"Yes, and we'll tell those students in that rowboat, too," said Mary.

"You came for a ride of your own free will," said Merwell.
