“That’s because we’re coming down from the north,” explained Jack, when Nick called out to mention this distressing fact. “You see, the trees all run together, and it’s next to impossible to tell where the mainland ends off and the key begins. But I think I get the dividing line through the glasses. Anyhow, I’m heading straight for it right now.”

Ten minutes later and Josh called out, to say that he could see the opening all right; and the others added their evidence to what he said.

“There’s the new breeze coming, Jack!” called Herb.

“Yes, and the harbor is so close too,” George put in, as he arose from his lowly position. “But I reckon my engine will go now, Jack. If you hear her crackle, please cast off that hawser, will you?”

“Sure!” sang out Jimmy, as he climbed forward, Jack having taken the wheel himself some little time previous, so as to be prepared for any emergency that might arise.

A moment later and there was a merry popping from the mended motor of the Wireless, and immediately Jimmy heard this he cast the rope loose.

“Better make a plunge for it, George; I’ll stand by Herb!” sang out Jack.

“But that wouldn’t look right,” objected George, though doubtless he would feel better satisfied if given a chance to make use of the great speed his boat could show under special conditions, in order to get in a harbor before the blow struck them.
