Frank’s body was lifted up and he was placed upon a rotting couch near. He was already regaining his consciousness.

But at this moment Warren gave a start. He placed his helmet to Parker’s and shouted:

“A danger signal from above!”

“What is it?”

“Wait until I can learn.”

Warren was enabled to speak through his tube with those on the Aurelian’s deck.

Presently he turned to Parker and said:

“A hurricane is coming up. Mate Clark has already got the anchor under way, and has recalled our boat.”

“Then we have got to give up the search for now?”

“Yes.”
