Meanwhile the hours passed. As the sun climbed the clear, steely lights vanished, the blue hazes deepened, and slowly the glistening surfaces of lava turned redder. Ladd was concerned to discover that Yaqui was missing from his outlook upon the high point. Jim Lash came out of the shady crevice, and stood up to buckle on his cartridge belt. His narrow, gray glance slowly roved from the height of lava down along the slope, paused in doubt, and then swept on to resurvey the whole vast eastern dip of the plateau.

"I reckon my eyes are pore," he said. "Mebbe it's this damn red glare. Anyway, what's them creepin' spots up there?"

"Shore I seen them. Mountain sheep," replied Ladd.

"Guess again, Laddy. Dick, I reckon you'd better flash the glass up the slope."

Gale adjusted the field glass and began to search the lava, beginning close at hand and working away from him. Presently the glass became stationary.

"I see half a dozen small animals, brown in color. They look like sheep. But I couldn't distinguish mountain sheep from antelope."

"Shore they're bighorn," said Laddy.

"I reckon if you'll pull around to the east an' search under that long wall of lava--there--you'll see what I see," added Jim.
