Dodging behind a life-raft Rusty and MacGregor went scurrying along in the dark and Johnny and Kopkina soon joined them.

“It—it’s just here,” Rusty whispered.

“We—we need a rope ladder,” Johnny exclaimed low.

“Here’s one,” came in MacGregor’s cheering voice. “Let her over easy now.”

“Now,” he breathed. “Over you go.”

The speed with which they went down that ladder, all but treading on one another’s fingers, would have done credit to the U. S. Navy.

“Now I’ll cut her loose,” said MacGregor. “All right, Rusty, turn her over.”

The fly-wheel whirled. The splendid motor began a low put-put-put. They were away into the dark.

“They’d have trouble findin’ us,” MacGregor murmured.

“But listen!” Johnny exclaimed.
