y down to meet the winter in the lower and less
rigorous valleys. Buck had already dragged down a stray part-grown calf;
but he wished strongly for larger and more formidable quarry, and he
came upon it one day on the divide at the head of the creek. A band of
twenty moose had crossed over from the land of streams and timber,
and chief among them was a great bull. He was in a savage temper, and,
standing over six feet from the ground, was as formidable an antagonist
as even Buck could desire. Back and forth the bull tossed his great
palmated antlers, branching to fourteen points and embracing seven feet
within the tips. His small eyes burned with a vicious and bitter light,
while he roared with fury at sight of Buck.

From the bull's side, just forward of the flank, protruded a feathered
arrow-end, which accounted for his savageness. Guided by that instinct
which came from the old hunting days of the primordial world, Buck
proceeded to cut the bull out from the herd. It was no slight task. He
would bark and dance about in front of the bull, just out of reach
of the great antlers and of the terrible splay hoofs which could have
stamped his life out with a single blow. Unable to turn his back on
the fanged danger and go on, the bull would be driven into paroxysms of
rage. At such moments he charged Buck, who retreated craftily, luring
him on by a simulated inability to escape. But when he was thus
separated from his fellows, two or three of the younger bulls would
charge back upon Buck and enable the wounded bull to rejoin the herd.

There is a patience of the wild--dogged, tireless, persistent as life
itself--that holds motionless for endless hours the spider in its web,
the snake in its coils, the panther in its ambuscade; this patience
belongs peculiarly to life when it hunts its living food; and it
belonged to Buck as he clung to the flank of the herd, retarding
its march, irritating the young bulls, worrying the cows with their
half-grown calves, and driving the wounded bull mad with helpless rage.
For half a day this continued. Buck multiplied himself, attacking from
all sides, enveloping the herd in a whirlwind of menace, cutting out his
victim as fast as it could rejoin its mates, wearing out the patience of
creatures preyed upon, which is a lesser patience than that of creatures
preying.

As the day wore along and the sun dropped to its bed in the northwest
(the darkness had come back and the fall nights were s
