"So it is!" shouted Benson. It was with difficulty that he made himself heard. "Here comes the worse of it!" he added.

A strange humming now filled the air, followed by twigs and flying branches. Overhead it was unusually dark, and they could scarcely see one another. Joe and Darry kept close together and clasped hands. Captain Moore was on one side of them and old Benson on the other.

As the wind struck the cliff it sent a shower of loose stones in all directions. Then it tore through the undergrowth where the horses were tethered. Next it seemed to hit the trees fronting the cliff. One tall monarch of the forest was twisted completely from its roots and began to topple.

"See, the tree is coming on top of us!" shrieked Joe.

His words were drowned out in the fury of the wind and the crashing of the tree. The next moment the monarch of the forest came down on the cliff with a bang, cracking the stone in several places. The bottom limbs caught those under the cliff and pinned them fast.

To both boys it seemed as if the end of the world had come. They rolled over, one on top of the other, and for several seconds lay dazed. Then they tried to get up, but found themselves unable to do so.

"Get off of my chest!" gasped Joe, who was underneath.

"I can't—I'm pinned down!" panted Darry.

"Boys, are you safe?" came from old Benson, who was also caught.

"I—I guess so!" answered Joe. "But it's a tight squeeze." Then the youth called out to his brother, but no answer came back.
