sing themselves to meet the increased distance of
objects. At first, the wall had leaped beyond his vision. He now saw it
again; but it had taken upon itself a remarkable remoteness. Also, its
appearance had changed. It was now a variegated wall, composed of the
trees that fringed the stream, the opposing mountain that towered above
the trees, and the sky that out-towered the mountain.

A great fear came upon him. This was more of the terrible unknown. He
crouched down on the lip of the cave and gazed out on the world. He was
very much afraid. Because it was unknown, it was hostile to him.
Therefore the hair stood up on end along his back and his lips wrinkled
weakly in an attempt at a ferocious and intimidating snarl. Out of his
puniness and fright he challenged and menaced the whole wide world.

Nothing happened. He continued to gaze, and in his interest he forgot to
snarl. Also, he forgot to be afraid. For the time, fear had been routed
by growth, while growth had assumed the guise of curiosity. He began to
notice near objects--an open portion of the stream that flashed in the
sun, the blasted pine-tree that stood at the base of the slope, and the
slope itself, that ran right up to him and ceased two feet beneath the
lip of the cave on which he crouched.

Now the grey cub had lived all his days on a level floor. He had never
experienced the hurt of a fall. He did not know what a fall was. So he
stepped boldly out upon the air. His hind-legs still rested on the cave-
lip, so he fell forward head downward. The earth struck him a harsh blow
on the nose that made him yelp. Then he began rolling down the slope,
over and over. He was in a panic of terror. The unknown had caught him
at last. It had gripped savagely hold of him and was about to wreak upon
him some terrific hurt. Growth was now routed by fear, and he ki-yi'd
like any frightened puppy.

The unknown bore him on he knew not to what frightful hurt, and he yelped
and ki-yi'd unceasingly. This was a different proposition from crouching
in frozen fear while the unknown lurked just alongside. Now the unknown
had caught tight hold of him. Silence would do no good. Besides, it was
not fear, but terror, that convulsed him.

But the slope grew more gradual, and its base was grass-covered. Here
the cub lost momentum. When at last he came to a stop, he gave one last
agonised yell and then a long, whimpering wail. Also, and quite as a
