"That chap must have been full of Arizona tangle-foot, to have fired as wild as he did," I ejaculated, and walked over to where the mail-car had stood, to see just how bad the shooting was. When I got there and faced about, it was really impossible to believe any man could have done so badly, for raising my own Winchester to the pole put it twenty degrees out of range and nearly forty degrees in the air. Yet there were the cartridge-shells on the ground, to show that I was in the place from which the shots had been fired. While I was still cogitating over this, the special train I had ordered out from Flagstaff came in sight, and in a few moments was stopped where I was. It consisted of a string of three flats and a box car, and brought the sheriff, a dozen cowboys whom he had sworn in as deputies, and their horses. I was hopeful that with these fellows' greater skill in such matters they could find what I had not, but after a thorough examination of the ground within a mile of the robbery they were as much at fault as I had been. "Them cusses must have a dugout nigh abouts, for they couldn't 'a' got away without wings," the sheriff surmised. I didn't put much stock in that idea, and told the sheriff so. "Waal, round up a better one," was his retort. Not being able to do that, I told him of the bullets in the telegraph pole, and took him over to where the mail car had stood. "Jerusalem crickets!" was his comment as he measured the aim. "If that's where they put two of their pills, they must have pumped the other four inter the moon." "What other four?" I asked. "Shots," he replied sententiously. "The road agents only fired four times," I told him. "Them and your pards must have been pretty nigh together for a minute, then," he said, pointing to the ground. I glanced down, and sure enough, there were six empty cartridge-shells. I stood looking blankly at them, hardly able to believe what I saw; for Albert Cullen had said distinctly that the train-robbers had fired only four times, and that the last three Winchester shots I had heard had been fired by himself. Then, without speaking, I walked slowly back, searching along the edge of the road-bed for more shells; but, though I went beyond the point where the last car had stood, not one did I find. Any man who has fired a Winchester knows that it drops its empty shell in loading, and I could therefore draw only one conclusion,--namely, that all seven discharges of the Winchesters had occurred up by the mail-car. I had heard of men supposing they had fired their guns through hearing another go off; but with a repeating rifle one has to fire before one can reload. The fact was evident that Albert Cullen either had fired his Winchester up by the mail-car, or else had not fired it at all. In either case he had lied, and Lord Ralles and Captain Ackland had backed him up in it. CHAPTER V A TRIP TO THE GRAND CAÑON
