“Go ahead. I am with you to the end.”

Gently and swiftly Frank made the opening in the vines larger, and then he quickly stepped through, holding them aside for his friend to follow.

The vines fell back into place, and the lad crouched close to the ground.

“There,” said Frank, “see that light? It is not a torch.”

“No. It seems to be some sort of lamp.”

“It is a miner’s lamp. Look—another is being lighted.”

A match flared up, and its bright glow revealed the pale and terrible face of the gorilla man, who was lighting the lamp.

The lamps were arranged to be placed in the hats of those who carried them, and this was what the two men did with them.

When everything was arranged to their satisfaction, Belmont and the dwarf started onward into the cave.

“We’ll follow them, Harry,” said Frank.
