To that end he first of all climbed the tallest pinon tree in sight; a tree that stood on a rise of ground apart from its brothers. From the concealment of its branches, he surveyed his surroundings carefully, noting especially the notched unevenness of the butte's rim and how just behind him it narrowed unexpectedly to a thin ridge not more than a couple of hundred yards in breadth. A jagged outcropping cut straight across and Casey saw how yesterday he had mistaken that ledge for the rim of the butte. His man must have been out on the point beyond him all the while. He was out there now, very likely; there, or down in the camp he had watched yesterday like a vulture.
His search having narrowed to an area easily covered in an hour or two, Casey turned his head and examined as well as he could the deep canyon that had bitten into the butte and caused that narrow peak. Trees blocked his view there, and he was feeling about for a lower foothold so that he could make the descent when a voice from the ground startled him considerably.
"Come down outa there, before I shoot yuh down!"
Casey looked down and saw what he afterwards declared was the meanest looking man on earth, pointing straight at him the widest muzzled shotgun he had ever seen in his life.
Casey came down. The last ten feet of the distance he made in a clean jump, planting his feet full in the old man's stomach. The meanest looking man on earth gave a grunt and crumpled, with Casey's fingers digging into his throat.
Whether Casey would have killed him or not will never be known. For just as the man was falling limp in his hands, another heavy body landed upon Casey's back. Casey felt a hard, chill circle pressed against his perspiring temple. His hands relaxed and fall away from the throat, leaving finger marks there in the flesh.
"Git up off'n him!" a new voice commanded harshly, and Casey obeyed. His captor shifted the gun muzzle to the back of Casey's neck and poked the gasping, bearded old man with his toe.
"Git up, Paw, you old fool, you! What'd you let 'im light on yuh fer? Why couldn't you a stood back a piece, outa reach? You like to got croaked."
Casey found it prudent to hold his head rather still, as a man does when he carries a boil on his neck. The muzzle of a six-shooter has a quieting effect, when applied to the person by an unfriendly hand. Casey did not at once see the intruder. But presently "Paw" recovered himself and his shotgun, and swung it menacingly toward Casey. Whereupon the cold circle left Casey's medulla oblongata and a long-faced, long-legged youth stepped somewhat hastily to one side.
"Paw, you ol' fool, you, get your finger off'n that trigger whilst you're aimin' at me!" he exclaimed pettishly.
