But he could not get the footprint out of his mind. He spent many sad
and fearful days thinking about it. "How could it have gotten there?
Whose was it? Was the owner savage or not? What did he want on the
island?" were some of the questions that haunted him.

"Perhaps," he thought one day, "I just imagined I saw a footprint, or
perhaps it was one of my own that I have made when going to sail my
boat." He took courage at this and began to go about the island again.
But he went in great fear, always looking behind him. He was always
ready to run at the first sign of danger. He had made himself a large,
strong, new bow and plenty of arrows. He carried these in a quiver he
had made from his cloth. He fashioned too a sharp-pointed, lance-like
weapon which he hurled with a kind of sling. In his belt he carried some
new sharpened stone knives. He had found a better kind of rock out of

Armed thus, he began to have more confidence. He had a strong desire to
see the footprint again and make up his mind about it. He wished to
measure it. In this way he could tell certainly whether it was a chance
print of his own foot or not. So, after a few days, he again ventured
across the island. Alas, on measuring the print it was much larger than
his own! There could no longer be any doubt that it belonged to someone
else.

Again great fear fell on poor Robinson. He shook with cold and fright.
He resolved to make himself more secure against attack.

He cut and carried willow stakes and set them in a thick hedge around in
front of his shelter. This was outside the first and enclosed it. In a
season or two these had grown to such a height as to shut out all view
of his home from sight to one coming to it from the front.

His flock of goats gave him many troubled thoughts. His goats were his
greatest treasure. From them he obtained without trouble his meat, his
milk and butter.

"What if they were discovered and killed or carried away?" He resolved
to divide his herd into three parts and secrete these in separate fenced
pastures in different parts of the island. His herd of goats now
numbered twenty-five. He made thorough search about the island for the
most secluded and best hidden spots where he could fence in a pasture.

One day as he was exploring on the west side of the island to find
another open space for a goat field, he thought he spie
