himself. But at last he came out on a narrow strip of rocks and sand, at a point where the Leming River made a broad turn.
The water at this point was quite shallow, and here he thought the progress of the motor-boat would be stayed. His surmise was correct, the craft bringing up between several smooth rocks. The engine continued to work, pounding the boat back and forth, and threatening to sink her.
Fortunately, Dave had on a pair of gaiters he had borrowed, and they were so big that he slipped them off with ease. His socks followed, and then he rolled up his trousers to his knees, and waded into the stream.
"Be careful, or you'll slip and hurt yourself on the rocks!" sang out the senator's son.
"I'm watching out!" returned Dave.
He was leaping from one smooth stone to another, keeping in the shallow spots as much as possible. Thus he managed to get within a few yards of the motor-boat.
As he came closer he saw that the craft was pounding on the rocks worse than before. The pounding had in some way moved the gasoline control forward and also advanced the spark, and the engine was practically running "wild."
"I hope she isn't getting ready to blow up!" thought the youth, and he gazed anxiously ahead.
