mperative need to be constantly alert; for these dogs and men
were not town dogs and men. They were savages, all of them, who knew no
law but the law of club and fang.

He had never seen dogs fight as these wolfish creatures fought, and his
first experience taught him an unforgetable lesson. It is true, it was
a vicarious experience, else he would not have lived to profit by it.
Curly was the victim. They were camped near the log store, where she, in
her friendly way, made advances to a husky dog the size of a full-grown
wolf, though not half so large as she. There was no warning, only a leap
in like a flash, a metallic clip of teeth, a leap out equally swift, and
Curly's face was ripped open from eye to jaw.

It was the wolf manner of fighting, to strike and leap away; but there
was more to it than this. Thirty or forty huskies ran to the spot and
surrounded the combatants in an intent and silent circle. Buck did not
comprehend that silent intentness, nor the eager way with which they
were licking their chops. Curly rushed her antagonist, who struck again
and leaped aside. He met her next rush with his chest, in a peculiar
fashion that tumbled her off her feet. She never regained them, This
was what the onlooking huskies had waited for. They closed in upon her,
snarling and yelping, and she was buried, screaming with agony, beneath
the bristling mass of bodies.

So sudden was it, and so unexpected, that Buck was taken aback. He saw
Spitz run out his scarlet tongue in a way he had of laughing; and he saw
Francois, swinging an axe, spring into the mess of dogs. Three men
with clubs were helping him to scatter them. It did not take long. Two
minutes from the time Curly went down, the last of her assailants were
clubbed off. But she lay there limp and lifeless in the bloody, trampled
snow, almost literally torn to pieces, the swart half-breed standing
over her and cursing horribly. The scene often came back to Buck to
trouble him in his sleep. So that was the way. No fair play. Once down,
that was the end of you. Well, he would see to it that he never went
down. Spitz ran out his tongue and laughed again, and from that moment
Buck hated him with a bitter and deathless hatred.

Before he had recovered from the shock caused by the tragic passing
of Curly, he received another shock. Francois fastened upon him an
arrangement of straps and buckles. It was a harness, such as he had seen
the grooms put on the horses at home. A
