Matt's eyes were behind, and the girl's in front of her.
"Oh, hurry, hurry!" she cried, in a frightened voice. "They've got a big touring car, and I don't think anything can keep them from overtaking us!"
[CHAPTER III.]
GEORGE'S SISTER.
Matt threw a look over his shoulder. Big John was just making a flying leap to the running board of a large car. He fell aboard in a huddle, colliding with the dash and striking violently against his young companion, who was at the steering wheel.
Matt was not able to look longer. By doing wonders with the spark and the steering wheel, and by ignoring the bubbling in the radiator and the pounding of the engine, he nursed the runabout along at a good rate of speed. A low hill was before them, and it came near killing the car, but when they had reached the crest and were ready for the descent on the other side, an exclamation from the girl drew his attention.
"What is it?" he asked. "Is that other car close upon us?"
"Something has gone wrong with the other automobile," was the answer. "When that man jumped aboard he must have injured something."
Matt looked around again. Big John and his companion were on the ground, looking over their car and trying to locate the trouble.
