shoulder.

"The Bull! the Bull!" yelped A'tim, crouching to steal under the
giant head, and lay him by the flank.

Famine-braved, the Wolves fought and snapped, and snarled the
Kill cry. Crazed beyond cowardice by the smell of their own
blood, the Cows fenced and thrust, and stood one against the
other--the sharp horns ripped like skinning-knives.

"Ee-e-yah! if I could but do it!" snarled the great Wolf. Ah! he
had her--by the nose! Down to her knees, dragged by the Wolf,
came the Cow that had turned Shag from the Death Flower.

"Yah, yah, yah!" snarled the Wolf joyously through his set teeth,
as the Cow bellowed loud in her agony of terror.

Then something like the falling of a great forest was heard, and
the Buffalo Bull descended upon the Big Wolf and blotted him out
from the light of the world. It was not a question of horns at
all; it was simply a great weight like an avalanche of rock
crushing him into the herbed plain. His grim jaws relaxed their
hold; from ears and nostrils flowed his mighty strength in a red
stream.

Even as Shag charged the Wolf, A'tim had reached for the Cow's

all the prairie arena: that was why A'tim fell short as he
reached for the death hold.

With a deft twist Shag had the Dog-Wolf pinned to the earth
between the worn old horns.

"Now, traitor," he grunted.

"Spare me," pleaded A'tim; "I, who am not of your kind, slept by
your side, and guided you to this land where you have a Herd. I
was forced to this by the Wolves--they threatened to eat me.
Spare me, Great Bull; I came to warn you, but the Wolves followed
fast."

Shag hesitated. One crunch from his broad forehead, one little
push--so, and the Dog-Wolf, who was A'tim, would--

[Illustration: "THOU ART A TRAITOR, AND A GREAT LIAR," SAID THE
BULL.]

"Spare me, Shag--let me go," pleaded the mongrel again; "I
brought you to this Herd--to this Northland which is good. Were
we not Outcast Brothers together?"

Again Shag hesitated. Why not? Wa
