"Who's attacking us?" added Nort. He, as had Dick, had also fired rapidly and with equal non-effect.

"Search me," succinctly replied Snake. "All I know is that there's somebody out there anxious to fill us full of lead—more anxious than I am to be filled," he added grimly. "Lay low everybody!" he shouted, as another burst of firing succeeded the calm that had followed the first attack.

Bullets "zinged" in amid the rocks, striking the hard stone with vicious "pings!" and leaving grim, gray marks on the boulders; marks that would have brought spots of vital redness had they found a human target.

Bud refilled the magazine of his gun, and started a return fire when Snake threw a piece of stone that fell near the boy rancher, thus attracting his attention. There was little use in shouting above the din. A voice could be heard only in the lulls of shooting.

"What's the matter?" yelled Bud, scarcely making himself heard.

Snake motioned for him to cease firing, an example followed by Nort and
Dick. As for the older cowboys they had wisely witheld their fire.

Explanation was made by Snake a moment later when he crawled over to Bud, keeping well hidden amid the rocks, and speaking in his ear, though yelling at the top of his voice as he did so, said:

"What's the use of shootin' when you can't see your mark? Save your powder and lead!"

It was good advice. Bud could not help but laugh at the conclusion of Snake's advice. For the cowboy had started to give it in tones that Yellin' Kid might have been proud to own. This was necessary because those in ambush were firing in full force it seemed. But they stopped suddenly, in the midst of Snake's remarks, so that the end of the cowboy's advice fell amid a silence, and, being delivered at full power must have been heard by the enemy.

Bud's laughter at this little incident was echoed by the others, and, for the moment, relieved the grim tension. But its grip tightened on all of them a moment later, as a bullet, viciously "zinging" its way amid the rocks, clipped a little from the lobe of the ear of one of the cowboys.
