But Chee-Chee and Gub-Gub did not know how to swim.

"Get the rope!" said Polynesia. "I told you it would come in handy. Where's that duck? Come here, Dab-Dab. Take this end of the rope, fly to the shore and tie it on to a palm- tree; and we'll hold the other end on the ship here. Then those that can't swim must climb along the rope till they reach the land. That's what you call a `life-line.'"

So they all got safely to the shore--some swimming, some flying; and those that climbed along the rope brought the Doctor's trunk and handbag with them.

But the ship was no good any more--with the big hole in the bottom; and presently the rough sea beat it to pieces on the rocks and the timbers floated away.

Then they all took shelter in a nice dry cave they found, high up in the cliffs, till the storm was over.

When the sun came out next morning they went down to the sandy beach to dry themselves.

"Dear old Africa!" sighed Polynesia. "It's good to get back. Just think--it'll be a hundred and sixty-nine years to-morrow since I was here! And it hasn't changed a bit! Same old palm-trees; same old red earth; same old black ants! There's no place like home!"
