d over in the powdery snow. Spitz gained his feet almost as
though he had not been overthrown, slashing Buck down the shoulder and
leaping clear. Twice his teeth clipped together, like the steel jaws of
a trap, as he backed away for better footing, with lean and lifting lips
that writhed and snarled.

In a flash Buck knew it. The time had come. It was to the death. As
they circled about, snarling, ears laid back, keenly watchful for the
advantage, the scene came to Buck with a sense of familiarity. He seemed
to remember it all,--the white woods, and earth, and moonlight, and the
thrill of battle. Over the whiteness and silence brooded a ghostly calm.
There was not the faintest whisper of air--nothing moved, not a leaf
quivered, the visible breaths of the dogs rising slowly and lingering in
the frosty air. They had made short work of the snowshoe rabbit, these
dogs that were ill-tamed wolves; and they were now drawn up in an

In vain Buck strove to sink his teeth in the neck of the big white dog.
Wherever his fangs struck for the softer flesh, they were countered by
the fangs of Spitz. Fang clashed fang, and lips were cut and bleeding,
but Buck could not penetrate his enemy's guard. Then he warmed up and
enveloped Spitz in a whirlwind of rushes. Time and time again he tried
for the snow-white throat, where life bubbled near to the surface, and
each time and every time Spitz slashed him and got away. Then Buck took
to rushing, as though for the throat, when, suddenly drawing back his
head and curving in from the side, he would drive his shoulder at the
shoulder of Spitz, as a ram by which to overthrow him. But instead,
Buck's shoulder was slashed down each time as Spitz leaped lightly away.

Spitz was untouched, while Buck was streaming with blood and pant
