The boys searched patiently.

Joe Hardy was nowhere to be found.

They did not dare scatter, for fear of losing one another, but they hunted among the rocks, realizing the hopeless nature of their quest. At last they halted, standing in a little group, with rain pouring down on them.

Frank expressed the fear they had all held for the past few minutes.

"I wonder if he could have fallen over the cliff!"

They had been going along within a few yards of the uneven edge of the cliff and they realized that, in the rain and the dim light, it would have been easy for Joe to have stumbled into the abyss. They turned sick at the thought of the frightful plunge, ending in certain death, had he tumbled over the verge.

Suddenly, above the roar of the storm, they heard a faint cry.

"Listen!" cried Frank.

Breathlessly, they waited.

Again came the cry.
