He looked down at the climber, who was about half way up the bluff. "Huh! I don't want to shoot him without givin' him a chance; but he just can't come up. Le's see: one, two, three; an' one in th' house, wounded, is four. There's a couple more somewhere, layin' low I reckon, waitin' for me to move across their sights."

He looked across at Red Shirt and grinned. "He's layin' on th' wrong side of that rock an' don't know it. I'll tell him, an' get rid of that climber at th' same time. Hope he busts his neck gettin' down."

Wriggling back from the edge so that the man in the house could not locate him by the smoke, he took deliberate aim at Red Shirt and gently squeezed the trigger. Red Shirt soared into the air and dove over the bowlder headfirst and with undignified speed.

"Knowed it was deceivin'," growled Johnny. "Shot plumb over him. Can't be more'n eight hundred yards. An' that's a fool color of a shirt to wear on a job like this."

Johnny's shirt had been blue, a long time back; but now its color hardly could be described by a single adjective. Sun, wind, and strong lye soap had taken their toll; and it had not been washed since he had left his little valley.

Wriggling back to the patch of grass, a quick glance below showed the climber frantically descending; and the man in the house was making lots of smoke on a gamble. Across the valley a gray-white cloud puffed out above the big rock and a little spurt of sand forty feet to Johnny's left told him that Red Shirt, too, was guessing.

"Must 'a' been asleep not to see my smoke," muttered Johnny.

More smoke rolled up from the bowlder and soon some pebbles not ten feet away from him scattered suddenly, while a high-pitched whine soared skyward.

"He's pluggin' at every bit of cover he can see," mused Johnny, wriggling back behind a rock. "An' he'll prospect that bunch of grass—knowed it! He can shoot," he exclaimed in ungrudging praise; "an' he's got th' range figgered to a foot. An' he's workin' steady from th' north to th' south; an' when he tries for that clump of brush over there he's got to show his head an' shoulder."

A puff of dust and sand fifty feet to his right told him to get ready; and then a bowlder south of the sand-puff said spat!
