mouth of the cave with a sudden shock of suspicion.
Faint, strange sounds came from within. They were sounds not made by his
mate, and yet they were remotely familiar. He bellied cautiously inside
and was met by a warning snarl from the she-wolf. This he received
without perturbation, though he obeyed it by keeping his distance; but he
remained interested in the other sounds--faint, muffled sobbings and
slubberings.

His mate warned him irritably away, and he curled up and slept in the
entrance. When morning came and a dim light pervaded the lair, he again
sought after the source of the remotely familiar sounds. There was a new
note in his mate's warning snarl. It was a jealous note, and he was very
careful in keeping a respectful distance. Nevertheless, he made out,
sheltering between her legs against the length of her body, five strange
little bundles of life, very feeble, very helpless, making tiny
whimpering noises, with eyes that did not open to the light. He was
surprised. It was not the first time in his long and successful life
that this thing had happened. It had happened many times, yet each time
it was as fresh a surprise as ever to him.

His mate looked at him anxiously. Every little while she emitted a low
growl, and at times, when it seemed to her he approached too near, the
growl shot up in her throat to a sharp snarl. Of her own experience she
had no memory of the thing happening; but in her instinct, which was the
experience of all the mothers of wolves, there lurked a memory of fathers
that had eaten their new-born and helpless progeny. It manifested itself
as a fear strong within her, that made her prevent One Eye from more
closely inspecting the cubs he had fathered.

But there was no danger. Old One Eye was feeling the urge of an impulse,
that was, in turn, an instinct that had come down to him from all the
fathers of wolves. He did not question it, nor puzzle over it. It was
there, in the fibre of his being; and it was the most natural thing in
the world that he should obey it by turning his back on his new-born
family and by trotting out and away on the meat-trail whereby he lived.

Five or six miles from the lair, the stream divided, its forks going off
among the mountains at a right angle. Here, leading up the left fork, he
came upon a fresh track. He smelled it and found it so recent that he
crouched swiftly, and looked in the direction in which it disappeared.
Then he tur
