He ran his left hand down the white face of the broncho. It hobbled as if to stagger up, and sank back dumb, faithful, trying to the end, one fore knee bent to rise, the neck outstretched. Wayland's right hand went swiftly close between eye and ear. He shot, in quick succession, three times, his hand fumbling, his sight turned aside. Neither spoke as they advanced down the other side of the sand ridge, the Ranger steadying himself with a hand to the mule's neck. The bank dipped to a white alkali pit where the light lay in dead pools, gray in the twilight, quivering with heat, layers of blue air above ashes of death. For the second time that day, the sand colored thing skulked across the trail. Wayland took hold of both bridles and led down, the old man wakening as from a stupor. The alkali pit lay perhaps a mile distant, gray and fading in the red light. "Wayland, is that water?" "Where? I can't see it." "There, at the foot of the hill." "With trees up side down? No, sir! It may be mirage of water miles away, carried by the rays of this twilight; but if you can see it and the horses can't smell it, you can bet on a false pool!" But the little mule had jerked free with a low squeal. "A tell you, Wayland, there is water;" and he began babbling again inconsequently of the sea, running his words together incoherent, half delirious. "Go on and see, then! I'll follow! If there's water, look out for the drovers." Wayland let go his hold of the bridle. Horse and mule shot down the sand bank. He saw them shoulder neck and neck along the white alkali bottom, then break to a gallop, the old man hanging to the pommel; then all disappeared round the end of the bank. Wayland slithered down the sand slope and dashed to the top of the next hill breathless. Below lay the glister of water, real water and no mirage, glassy, gray and sinister. The Ranger uttered a yell; then paused in his head-long descent. The pony had plunged in belly deep; the mule had lowered its head; the old man was kneeling at the brink. Wayland saw him lave the water up with his hand: then throw it violently back. All at once, the grip of life snapped. Matthews was lying motionless on the sand. The horse was chocking its head up and down; the mule was stamping angrily with fore feet roiling the pool bottom. It had been one of the salt sinks that lie in the depressions of the Desert.
