"Nine hundred yards to that black spot," said Mills. "The spot's a bit of a hole in the ground. Twelve hundred to the big boulder."

He rose off the stone he was sitting on and lay down on the path, belly under, and ran up the back sight of his rifle with care. Flinging back the bolt, he blew into the chamber and thrust a cartridge in; tested the air with a wet finger, and wriggled the butt home into his shoulder. Dave watched him in silence; Mills was, he knew, a good shot, and he was now preparing, with all the little tricks and graces of the rifle-range, to pull trigger on the man he had risked—nay, almost thrown away—his life to save from the consequences of an unspeakable crime.

"Ah!" breathed Mills, with an artist's luxurious satisfaction.

Down the valley a figure had broken from the bush, and was plainly to be seen against the red ground. The men on the hill flopped down and prepared to shoot.

"Don't fire," Dave warned the others. He was watching Mills. The trader's face bore no signs of his recent mental struggle. It carried no expression whatever, save one of cool interest, just touched with a craftsman's confidence. His barrel was steady as his head. The little figure below was moving over the rough ground towards the black spot. They could see its legs working grotesquely, like a mechanical toy.

"So," murmured Mills. "Now just a little farther. So!"

He fired.

There was no leap into the air, no tragic bound and sprawling tumble.
The little figure in the valley fell where it was, and never moved.

Mills jerked open his breech.

"I'll bet that took him in the spine," he said.
