increasing suddenly, shook the house furiously about them.

It was a north wind, and traveled south before the rider of the strong
roan. Over a thousand miles of plain and hills it passed, and down
into the cattle country of the mountain-desert which the Rockies hem
on one side and the tall Sierras on the other.

It was a trail to try even the endurance of Pierre and the strong
roan, but the boy clung to it doggedly. On a trail that led down from
the edges of the northern mountain the roan crashed to the ground in a
plunging fall, hitting heavily on his knees. He was dead before the
boy had freed his feet from the stirrups.

Pierre threw the saddle over his shoulder and walked eight miles to
the nearest ranch house, where he spent practically the last cent of
his money on another horse, and drove on south once more.

There was little hope in him as day after day slipped past. Only the
ghost of a chance remained that Martin Ryder could fight away death
for another fortnight; yet Pierre had seen many a man from the
mountain-desert stave off the end through weeks and weeks of the
bitterest suffering. His father must be a man of the same hard durable
metal, and upon that Pierre staked all his hopes.

And always he carried the picture of the dying man alone with his two
wolf-eyed sons who waited for his eyes to weaken. Whenever he thought
of that he touched his horse with the spurs and rode fiercely for a
time. They were his flesh and blood, the man, and even the two
wolf-eyed sons.
