Venters gasped in amazement. Had the wild sorrel gone mad? His head was high and twisted, in a most singular position for a running horse. Suddenly Venters descried a frog-like shape clinging to Wrangle’s neck. Jerry Card! Somehow he had straddled Wrangle and now stuck like a huge burr. But it was his strange position and the sorrel’s wild scream that shook Venters’s nerves. Wrangle was pounding toward the turn where the trail went down. He plunged onward like a blind horse. More than one of his leaps took him to the very edge of the precipice. Jerry Card was bent forward with his teeth fast in the front of Wrangle’s nose! Venters saw it, and there flashed over him a memory of this trick of a few desperate riders. He even thought of one rider who had worn off his teeth in this terrible hold to break or control desperate horses. Wrangle had indeed gone mad. The marvel was what guided him. Was it the half-brute, the more than half-horse instinct of Jerry Card? Whatever the mystery, it was true. And in a few more rods Jerry would have the sorrel turning into the trail leading down into the cañon. “No—Jerry!” whispered Venters, stepping forward and throwing up the rifle. He tried to catch the little humped, frog-like shape over the sights. It was moving too fast; it was too small. Yet Venters shot once... twice... the third time... four times... five! All wasted shots and precious seconds! With a deep-muttered curse Venters caught Wrangle through the sights and pulled the trigger. Plainly he heard the bullet thud. Wrangle uttered a horrible strangling sound. In swift death action he whirled, and with one last splendid leap he cleared the cañon rim. And he whirled downward with the little frog-like shape clinging to his neck! There was a pause which seemed never ending, a shock, and an instant’s silence. Then up rolled a heavy crash, a long roar of sliding rocks dying away in distant echo, then silence unbroken. Wrangle’s race was run. CHAPTER XVIII. OLDRING’S KNELL Some forty hours or more later Venters created a commotion in Cottonwoods by riding down the main street on Black Star and leading Bells and Night. He had come upon Bells grazing near the body of a dead rustler, the only incident of his quick ride into the village.
