The situation was growing serious, and, since this particular Comanche was so defiant, Avon decided that the occasion was a good one for the use of a repeating weapon. Without pausing to take special aim, he fired three times in rapid succession at his foe. Though the latter escaped for the moment, his steed was less fortunate. He was hit hard by the first shot, while the last brought him to earth with a bullet through his brain. His rider was too nimble to be caught by the fall, but, leaping clear, ran swiftly across the plain in the effort to get beyond reach of the rifle, which seemed to be raining bullets all around him. His courage had given place to panic, and as he ran he bounded from side to side and up and down with the grotesque contortions of a Digger Indian when seeking to baffle the aim of an enemy. Avon continued his fusillade, and by a piece of pure accident winged the fugitive. He did not fall, but the height of his leap and the resonance of his outcry, instantly succeeded by a pronounced limp in his gait, left no doubt that he had gotten in the path of the hurtling messenger. "How are you making out, Baby?" asked Captain Shirril, turning his head and coolly scrutinizing his relative. "Only fairly," replied Avon, replenishing the magazine of his gun and keeping his gaze on the plain in front. "It is well enough to drop a mustang, but it is better to tumble their riders off them." "I meant to do that, but failed." The natural supposition of the friends was that the hot reception they had given their assailants would check them, and cause their withdrawal beyond the deadly range of their Winchesters. The reports must have reached the cowboys, and both glanced at the ridge to the west, over which they expected to see their comrades coming to their rescue. But the Comanches could not have failed to know of the presence of others near at hand, which fact warned them that whatever they did must be done quickly. Instead of falling back, therefore, because of the loss of a single warrior and steed, they rallied and pushed the fight with greater vigor than ever. In the face of the cracking Winchesters they rode closer than before, and then branching apart, put their animals on a run while they discharged their guns from every conceivable position. Instead of wheeling about as at first, they kept them straight away on the circle, which being less than before, enabled them to circumnavigate the defenders in a brief space of time. The captain and his nephew had their hands full, for assailants were on every side of them, and the popping of their guns was continuous. The attack was so serious, and the defenders were in such a conspicuous position, that it was impossible to escape the storm of bullets flying all around them. A quick start on the part of Thunderbolt showed that he had been hit, while almost at the same moment the rearing of the captain's mustang proved that he, too, was hurt.
