is comes from the daily movement of the sun. He
determined to study the matter more carefully.

Robinson got up and with great effort walked to the spring. There he
cooled his burning feet, and gathered some large leaves, which he bound
on them. He decided to remain in his cave a few days, for he had enough
food stored up to last him some length of time. He planned how he might
make himself a pair of shoes. As soon as his feet were well, he sought
out some thick bark and put fastenings of tough, strong fiber on it.
These served very well to protect his feet.

But he must have some further protection from the sun. It beamed so hot
that his hat was not enough. He made a parasol out of leaves like his
hat. He took a straight stick for a handle. He tied some reeds together
and bent them into a hoop. He then fastened the upper end of the stick
in the center of the hoop by means of six reeds which formed the ribs of
the parasol. To keep out the sun he covered this framework with large,
broad leaves. With a cord he tied the stem ends of the leaves to the
stick just above where the reeds were tied.

Spread out, these broad leaves completely covered the ribs. Their tips
reached over the hoop. They were fastened together by means of small,
needle-like fish-bones Robinson had found on the beach.

GETTING FIRE

Now Robinson had heard that savages take two dry pieces of wood and rub
them so long on each other that they at length begin to burn.

He tried it. The sweat ran down his cheeks, but every time the wood was
about to catch fire his strength would give out, and he was obliged to
rest, and when he began again the wood was cold.

"How will it be in winter," he cried, "when it is cold, and I have no
fire?" He must try other ways of preparing meat for his table. He must
think of some other way of getting fire. He remembered that once, when a
boy at home, he had in playing with a stick made it hot by twirling it
on end on a piece of wood. "I will try this," he thought. He searched
for a good hard stick and a piece of wood upon which to turn or twirl it
with his hands. Having found the best materials at hand, he began to
twirl the stick. He made a little hollow in the block of wood in which
to turn his upright stick. There was heat but no fire. He twirled and
twirled, but he could not get the wood hot enough to blaze up or ignite.
He had not skill. Besides his hands were not used to such rough
treatment. Soon t
