“Keep your foot on the soft pedal,” he advised, in a whisper, for the two lads were on the front seat, with Bob in the rear. “No use getting him ruffled again.”

The three chums had taken advantage of a fine spring day to take a ride in their auto about the country near Cresville, a town not far from Boston. They had not gone far before they came to a delightful spot, where a roadside spring offered a chance to drink, and they took it. In stopping the car, Jerry had thrown out the switch, and when, with their thirst quenched, they wanted to start off again, the incident I have just narrated took place.

But now everything seemed to have been smoothed out, though Bob thought to himself that he had gotten a little the best of the bargain. He felt sure his chums had played no trick on him, in having him crank up without the switch being on, for it frequently had happened before that one of them forgot to make the electrical connection.

“But I get out of that tire work,” thought Bob, as the car swung along; “and they won’t guy me when I want something to eat. I guess we’re even.”

“Going to any place in particular?” asked Ned of Jerry, as the tall lad swung the machine around a curve.

“No, I just thought we’d run out for ten miles or so, and get back in time for lunch. Or we can stop at a roadhouse, and spend the whole day touring if you like. I was going——”

“Look out!” suddenly yelled Bob, for Jerry had turned to speak to Ned, and his eyes were not on the road ahead. “Look out or you’ll go over that dog!”

There was a scurrying in the dust as a yellow cur rushed from a roadside house, directly at the auto. Bob spoke only just in time, for Jerry, with a quick turn of the wheel, sent the car to one side with a dangerous swerve, but avoiding the dog.

The beast, with sharp barks, seemed to enjoy the confusion he had caused. Jerry, with muttered comments on all such dogs in general, and this one in particular, was swinging back into the road again, when there came a sharp hiss of air, and the auto settled slightly on one side.

“Oh, rats!” cried Ned. “A puncture!”
