“Who threw that?” he exclaimed.
Whizz! came another stone. It struck Harry in the cheek, drawing blood.
“Whoa!” yelled Jerry, and while the horses were still in motion, he leaped to the road.
He had noted the direction from which the missiles came, and bound off, but behind the bushes all was dark.
“Look out for yourself!” cried Harry.
He was busy with the horses, who were shying first to one side and then to the other.
At first Jerry could see nothing, but soon he discovered two forms in the semi-darkness.
He rushed over and found himself face to face with Si Peters and Wash Crosby.
“Peters!” he ejaculated.
Scarcely had he spoken when a club was raised. Jerry tried to avoid the descending blow, but was only partly successful.
