ure," said the parrot; "but I think we're ship-wrecked. Tell
the duck to get out and see."

So Dab-Dab dived right down under the waves. And when she came up she
said they had struck a rock; there was a big hole in the bottom of the
ship; the water was coming in; and they were sinking fast.

"We must have run into Africa," said the Doctor. "Dear me, dear
me!--Well--we must all swim to land."

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!"

And the others noticed she had tears in her eyes--she was so pleased to
see her country once again.

Then the Doctor missed his high hat; for it had been blown into the sea
during the storm. So Dab-Dab went out to look for it. And presently
she saw it, a long way off, floating on the water like a toy-boat.

When she flew down to get it, she found one of the white mice, very
frightened, sitting inside it.

"What are you doing here?" asked the duck. "You were told to stay
behind in Puddleby."

"I didn't want to be left behind," said the mouse. "I wanted to see
what Africa was like--I have relatives there. So I hid in the baggage
and was brought on to the ship with the hard-tack. When the ship sank
I was terribly frightened--because I cannot swim far. I swam as long
as I could, but I soon got all exhausted and thought I was going to
sink. And then, just
