WHAT MAKES AN ISLAND FLOAT

VERY early in our experience of Popsipetel kindness we saw that if we

were to get anything done at all, we would almost always have to do it

secretly. The Doctor was so popular and loved by all that as soon as he

showed his face at his door in the morning crowds of admirers, waiting

patiently outside, flocked about him and followed him wherever he went.

After his fire-making feat, this childlike people expected him, I

think, to be continually doing magic; and they were determined not to

miss a trick.

It was only with great difficulty that we escaped from the crowd the

first morning and set out with Long Arrow to explore the island at our

leisure.

In the interior we found that not only the plants and trees were

suffering from the cold: the animal life was in even worse straits.

Everywhere shivering birds were to be seen, their feathers all fluffed

out, gathering together for flight to summer lands. And many lay dead

upon the ground. Going down to the shore, we watched land-crabs in

large numbers taking to the sea to find some better home. While away to

the Southeast we could see many icebergs floating—a sign that we were

now not far from the terrible region of the Antarctic.

As we were looking out to sea, we noticed our friends the porpoises

jumping through the waves. The Doctor hailed them and they came inshore.

He asked them how far we were from the South Polar Continent.

About a hundred miles, they told him. And then they asked why he wanted

to know.

“Because this floating island we are on,” said he, “is drifting

southward all the time in a current. It’s an island that ordinarily

belongs somewhere in the tropic zone—real sultry weather, sunstrokes

and all that. If it doesn’t stop going southward pretty soon everything

on it is going to perish.”

“Well,” said the porpoises, “then the thing to do is to get it back

into a warmer climate, isn’t it?”

“Yes, but how?” said the Doctor. “We can’t _row_ it back.”

“No,” said they, “but whales could push it—if you only got enough of

them.”

“What a splendid idea!—Whales, the very thing!” said the Doctor. “Do

you think you could get me some?”

“Why, certainly,” said the porpoises, “we passed one herd of them out

there, sporting about among the icebergs. We’ll ask them to come over.

And if they aren’t enough, we’ll try and hunt up some more. Better have

plenty.”

“Thank you,” said the Doctor. “You are very kind—By the way, do you

happen to know how this island came to be a floating island? At least

half of it, I notice, is made of stone. It is very odd that it floats

at all, isn’t it?”

“It is unusual,” they said. “But the explanation is quite simple. It

used to be a mountainous part of South America—an overhanging part—sort

of an awkward corner, you might say. Way back in the glacial days,

thousands of years ago, it broke off from the mainland; and by some

curious accident the inside of it, which is hollow, got filled with

air as it fell into the ocean. You can only see less than half of

the island: the bigger half is under water. And in the middle of it,

underneath, is a huge rock air-chamber, running right up inside the

mountains. And that’s what keeps it floating.”

“What a pecurious phenometer!” said Bumpo.

“It is indeed,” said the Doctor. “I must make a note of that.” And out

came the everlasting note-book.

The porpoises went bounding off towards the icebergs. And not long

after, we saw the sea heaving and frothing as a big herd of whales came

towards us at full speed.

They certainly were enormous creatures; and there must have been a good

two hundred of them.

“Here they are,” said the porpoises, poking their heads out of the

water.

“Good!” said the Doctor. “Now just explain to them, will you please?

that this is a very serious matter for all the living creatures in this

land. And ask them if they will be so good as to go down to the far end

of the island, put their noses against it and push it back near the

coast of Southern Brazil.”

The porpoises evidently succeeded in persuading the whales to do as the

Doctor asked; for presently we saw them thrashing through the seas,

going off towards the south end of the island.

Then we lay down upon the beach and waited.

After about an hour the Doctor got up and threw a stick into the water.

For a while this floated motionless. But soon we saw it begin to move

gently down the coast.

“Ah!” said the Doctor, “see that?—The island is going North at last.

Thank goodness!”

Faster and faster we left the stick behind; and smaller and dimmer grew

the icebergs on the skyline.

The Doctor took out his watch, threw more sticks into the water and

made a rapid calculation.

“Humph!—Fourteen and a half knots an hour,” he murmured—“A very nice

speed. It should take us about five days to get back near Brazil. Well,

that’s that—Quite a load off my mind. I declare I feel warmer already.

Let’s go and get something to eat.”
