came no
more; and though he listened through long vigils, the mournful howl was
never raised.

He began to sleep out at night, staying away from camp for days at a
time; and once he crossed the divide at the head of the creek and went
down into the land of timber and streams. There he wandered for a week,
seeking vainly for fresh sign of the wild brother, killing his meat as
he travelled and travelling with the long, easy lope that seems never to
tire. He fished for salmon in a broad stream that emptied somewhere into
the sea, and by this stream he killed a large black bear, blinded by
the mosquitoes while likewise fishing, and raging through the forest
helpless and terrible. Even so, it was a hard fight, and it aroused the
last latent remnants of Buck's ferocity. And two days later, when he
returned to his kill and found a dozen wolverenes quarrelling over the
spoil, he scattered them like chaff; and those that fled left two behind
who would quarrel no more.

The blood-longing became stronger than ever before. He was a killer, a
thing that preyed, living on the things that lived, unaided, alone,
by virtue of his own strength and prowess, surviving triumphantly in a
hostile environment where only the strong survived. Because of all this
he became possessed of a great pride in himself, which communicated
itself like a contagion to his physical being. It advertised itself
in all his movements, was apparent in the play of every muscle, spoke
plainly as speech in the way he carried himself, and made his glorious
furry coat if anything more glorious. But for the stray brown on his
muzzle and above his eyes, and for the splash of white hair that ran
midmost down his chest, he might well have been mistaken for a gigantic
wolf, larger than the largest of the breed. From his St. Bernard father
he had inherited size and weight, but it was his shepherd mother who
had given shape to that size and weight. His muzzle was the long wolf
muzzle, save that was larger than the muzzle of any wolf; and his head,
somewhat broader, was the wolf head on a massive scale.

His cunning was wolf cunning, and wild cunning; his intelligence,
shepherd intelligence and St. Bernard intelligence; and all this, plus
an experience gained in the fiercest of schools, made him as formidable
a creature as any that intelligence roamed the wild. A carnivorous
animal living on a straight meat diet, he was in full flower, at the
high tide of his life, overspi
