the rigging like a legion of demons. To add to the turmoil some casks
got loose and went rolling and crashing about till they finally went
overboard as a great wave toppled aboard.

"We must see how the professor is getting on," said, or rather yelled,
Frank suddenly.

He and the boys entered the cabin structure aft, which seemed warm and
cosy with its light and warmth after the turmoil of the terrific
battle of the elements outside.

But a prolonged search failed to reveal any trace of the man of
science.

Where could he be?

A scrutiny of his cabin, even looking under the bunk, failed to reveal
him. The boys began to fear he might have been swept overboard, when
suddenly Frank exclaimed:

"Perhaps he is in his laboratory."

"Hiding there?" asked Billy.

"No, I don't think so. The professor, whatever his oddities may be, is
no coward," rejoined Frank.

"No, his search for the Patagonian dog-flea proved that," agreed
Harry.
