The boys were proceeding rather slowly as they had not yet familiarized themselves with the lake and their bearings, and they did not want to run into anything.

For a while the Dartaway skimmed along, there being no other craft near. The water lapped the sides and broke away in a ripple of silver waves.

Suddenly Jerry threw out the gear clutch, and began spinning the wheel around. At the same instant Bob and Ned, who had been looking to the rear, turned around and saw a big black shape in front of them.

“Ahoy there! Schooner ahoy!” called Jerry. “What do you mean by cruising about without a light. You’ve no right to do that. Look out there. You’ll foul us!”

The sound of feet running about on a deck could be heard. Then there came a moment of silence followed by a sudden jar and a grinding crash.

The shock threw the Dartaway back. Jerry had already turned off the power, and was slowing down for the reverse when the smash came. The motor boat had fairly poked her nose into the side of the schooner.

“Are we damaged?” cried Ned.
