At the sound of Dave's voice the youth on the leaves opened his eyes for a moment.

"Take me back to school!" he gasped. "Don't—don't let the trolley run over me!"

"Frank, you are safe now—nothing is going to hurt you," said the senator's son. "Tell us where you are hurt."

"I—I——" Frank Bond stared around him. "I thought it was the Plum crowd after me! Whe—where did you come from?"

"From the school. We came out to look for you."

"Oh!"

"What about your hurts?" asked Ben.

"Oh, I got my arm hurt, and my leg, and I fell down and cut my face," answered the sufferer. "I—I don't know how I got here, and I didn't know the way home, and I got hungry and sleepy, and—and——" Frank Bond could not go on, but burst into tears.

"We'll fix you up," said Dave, kindly. "We've brought some lunch with us and you shall have all you want. Start up that fire briskly, fellows."

The fire was built up in good shape, and two torches were brought into the cavern. Then Frank Bond was propped up against a wall and given something to eat and to drink. He was very hungry and ate up fully half of what the four boys carried. Water was then brought in from the creek and his several wounds were washed and dressed. Fortunately none of them was serious, although they had been very painful.
