The exclamation at once called the attention of the four to the little grated window, through which Guadalupe was looking when seized by the bandits, and Donald threw himself down beside the dog and peered into the space below.

“What do you see?” asked Adrian.

“Three figures,” whispered Donald, “but I can’t make out who they are. I wish we could pull out these iron bars!”

He seized the grating and pulled with all his might, but the bars refused to yield.

“If we only had a crowbar!” he exclaimed.

“Beat them down,” came a voice from below.

Donald started back in surprise for just a moment, then put his face close to the bars and whispered back:

“What did you say?”

“Beat the bars down! They are only held in their place by a frame which must be rotten.”

Donald repeated the instructions to the others.
