The occupant of the wagon turned to look at the lad. Tom saw that
she was a handsome young lady. "Grab the reins!" he cried again.
"Pull hard!"

"I--I can't!" she answered frightenedly. "They have dropped down!
Oh, do please stop the horse! I'm so--so frightened!"

"I'll stop him!" declared the youth firmly, and he set his teeth
hard. Then he saw the reason the fair driver could not grasp the
lines. They had slipped over the dashboard and were trailing on the
ground.

The horse was slacking speed a bit now, for the pace was telling on
his wind. Tom saw his opportunity, and with a sudden burst of energy
was at the animal's head. Steering his wheel with one hand, with the
other the lad made a grab for the reins near the bit. The horse
swerved frightenedly to one side, but Tom swung in the same
direction. He grasped the leather and then, with a kick, he freed
himself from the bicycle, giving it a shove to one side. He was now
clinging to the reins with both hands, and, being a muscular lad and
no lightweight, his bulk told.

"Sit--still!" panted our hero to the young woman, who had arisen to
the seat. "I'll have him stopped in half a minute now!"

It was in less time than that, for the horse, finding it impossible
to shake off the grip of Tom, began to slow from a gallop to a trot,
then to a canter, and finally to a slow walk. A moment later the
horse had stopped, breathing heavily from his run.
