Into the eyes of the halfbreed came a viperish light that almost stilled Oliver's heartbeats. For an instant he feared that he had gone too far, that Foss was about to shoot him down in cold blood.

Foss stood spread-legged in the path, as before, his face twisting with anger, the fingers of his left hand clinching and unclinching themselves. Then Oliver almost ceased to breathe as a silent, dark figure slipped wraithlike from the chaparral and began stealing toward the back of Digger Foss.

"That settles it," said Foss. "I'll kill you for that, gems or no gems! Get ready! If you let down a hand while I'm puttin' up my gun I'll kill you like that!" He snapped the fingers of his left hand.

"I'll stick by my bargain," Oliver assured him, his glance struggling between Foss and that silent figure slinking in his rear.

What should he do? There was murder in the black eyes of the man who stole so stealthily upon the gunman's back. Should he shout to Foss? His sense of fair play cried out that he should. But Foss might misinterpret the meaning of his upraised voice, and fire. Should he—

"Here goes! I'm puttin' up my gun. Get ready, kid! When I—"

There was a leap, a flash of steel in the sunlight, a scream of agonizing pain.

Oliver's gun was out and levelled; but Foss was staggering from side to side, his arms limp before him, his head lopped forward as if he searched for something on the ground. He collapsed and lay there gasping hideously in the path, in a growing pool of blood.

The chaparral opened and closed again; and then only Oliver and the man in his death throes were remaining.

Even as Bolivio had died, so died Digger Foss, in a path in the wilderness, with the knife of a Showut Poche-daka in his back.
