"That was very neatly done, Dick," he said, when the thunder of the pounding hoofs had died away in the up-river distances. "Is it going to bump those fellows off of our trail?"

The water-boy was humped over the horn of his saddle as if he had found a stomach-ache in the breathless gallop. But he was merely listening.

"I ain't reskin' any money on it," he qualified. "If them cow-punch's 've caught on to where you're goin', and what you're goin' fer——"

Out of the stillness filling the hill-gorge like a black sea of silence came a measured thudding of hoofs and an unmistakable squeaking of saddle leather. Like a flash the boy was afoot and reaching under his bronco's belly for a tripping hold on the horse's forefoot. "Down! and pitch the cayuses!" he quavered stridently; and as the three horses rolled in the dry sand of the arroyo bed with their late riders flattened upon their heads, the inner darkness of the gorge spat fire and there was a fine singing whine of bullets overhead.

THE RUSTLERS

In defiance of all the laws of precedence, it was the guest who first rose to the demands of the spiteful occasion. While Ballard was still struggling with the holster strappings of his rifle, Bigelow had disengaged his weapon and was industriously pumping a rapid-fire volley into the flame-spitting darkness of the gorge.

The effect of the prompt reply in kind was quickly made manifest. The firing ceased as abruptly as it had begun, a riderless horse dashed snorting down the bed of the dry arroyo, narrowly missing a stumbling collision with the living obstructions lying in his way, and other gallopings were heard withdrawing into the hill-shadowed obscurities.

It was Ballard who took the water-boy to task when they had waited long enough to be measurably certain that the attackers had left the field.
