But the mules were weak, and the soil of the plain was a thin loam into which the wheels sank easily, so that the heavy wagons could not be hurried beyond a trot, and before long were reduced to a walk. Thus, while the caravan was still half a mile from its city of refuge, the foremost hornets of Delgadito's swarm were already circling around it. The chief could not charge at once, however, for the warriors whom he had in hand numbered barely a score, and their horses, blown with a run of over five miles, were unfit for sharp fighting work. For a few minutes nothing happened, except that the caravan continued its silent, sullen retreat, while the pursuers cantered yelling around it at a safe distance. Not a shot was fired by the emigrants; not a brave dashed up to let fly his arrows. At last there were fifty Apaches; then there was a hurried council; then a furious rush. Evidently the savages were ashamed to let their enemies escape for lack of one audacious assault. This charge was led by a child. A boy not more than fourteen years of age, screaming like a little demon and discharging his arrows at full speed with wicked dexterity, rode at the head of this savage _hourra_ of the Cossacks of the American desert. As the fierce child came on, Coronado saw him and recognized him with a mixture of wonder, dread, and hate. Here was the son of the false-hearted savage who had accepted his money, agreed to do his work, and then turned against him. Should he kill him? It would open an account of blood between himself and the father. Never mind; vengeance is sweet; moreover, the youngster was dangerous. Coronado raised his revolver, steadied it across his left arm, took a calm aim, and fired. The handsome, headlong, terrible boy swayed forward, rolled slowly over the pommel of his saddle, and fell to the ground motionless. In the next moment there was a general rattle of firearms from the train, and the mass of the charging column broke up into squads which went off in aimless caracolings. Barring a short struggle by half a dozen braves to recover the young chief's body, the contest was over; and in two minutes more the Apaches were half a mile distant, looking on in sulky silence while the train crawled toward the protecting bluff. "Hurrah!" shouted Thurstane. "That was quick work. Delgadito doesn't take his punishment well." "Reckon they see we had friends," observed Captain Glover. "Jest look at them critters pile down the mounting. Darned if they don't skip like nanny-goats."
