Suddenly a cry came from Harry, and he clutched Merriwell’s arm with quivering fingers, pointing with his other hand.
“Look! look!” he exclaimed. “The dwarf—there he is!”
Sure enough, the crouching figure of Apollo was seen emerging from the darkness of a black opening and advancing toward the girl with swift, catlike steps.
The girl had heard Harry’s exclamation, and, startled, she looked up toward where the boys were standing.
Then the dwarf rushed upon her and clutched her with his iron hands.
A scream of terror came from the lips of the frightened girl, and rang in weird echoes through the cave.
The hand of Apollo was pressed over her mouth.
But that scream had been heard, and there was an answering shout from not very far away.
The girl struggled, but the dwarf dragged her along toward the dark opening.
“How can we get down there, Frank? We must take a hand! How can we do it? It is too far to jump!”
