steady torture.

In another half hour he asked for water, as they paused for Sandersen
to mount, and Lowrie to take his turn on foot. Sandersen snatched the
canteen which Quade reluctantly passed to the injured man.

"Look here!" said Sandersen. "We got to split up on this. You sit there
and ride and take it easy. Me and the rest has to go through hell. You
take some of the hell yourself. You ride, but we'll have the water, and

foothills still wavered in blue outlines that meant distance--terrible

it first, and a harsh shout of joy came from the others. Quade was
walking. He lifted his arms to the cloud of dust as if it were a vision
of mercy. To Hal Sinclair it seemed that cold water was already running

first cry of hoarse joy, a silence was on the others, and gradually he
saw a shadow gather.

riders; it comes too fast for that. And it ain't the wind; it comes too
slow. But it ain't men. You can lay to that!"
