The tired dog had before him a long and dangerous run of about twenty miles, during which he would have to pass twice through the cordon of watchful Indians surrounding my comrades; but it was the only hope of saving the men, and Found seemed able and willing for the undertaking. I felt confident that if the Kiowas did not kill or cripple him, Found would make the trip quickly. He had already evaded the Indians in returning to camp, and I felt strong hopes that his almost human intelligence would carry him through. Found's first move on going out of the dugout was to go up on the roof and stand there for a little while sniffing the air. Then he turned and trotted to the ravine, up which he went at a run. My nest in the hay was a good enough point for observation but not for defence, but I went back there to think things over. The waning moon would rise about midnight. If the Indians waited till then before attacking I should command a somewhat clearer view of my surroundings. I thought that the dog should reach the wagon in an hour after leaving me and felt sure that it would not be long after that before he set out on his longer run to the fort. This should take two or three hours, and I could only guess the time that would be occupied in awakening Bill and his dressing and rousing Saunders and then getting out Saunders' company. It seemed to me the troops ought to be on the way by midnight at the latest, and they ought to reach my companions in two hours from that time. I had heard no shots from the direction of the wagon since dark, but a long time after the dog had left me, and while I was watching for the rising moon, I heard a shot or two, apparently from the rifles of the Indians, with no reply from the guns of my comrades. I supposed--rightly, as I afterward learned--that Found had reached the wagon and that the two men, by lighting matches to read my note, had drawn the fire from the Indians. On the other hand, it seemed to me possible that the Indians might have seen the dog and killed him. At length a little light appeared in the east. The moon was about to rise, and it must be after midnight. When the moon looked over the tops of the timber and the light grew, I began to scrutinize objects in my vicinity and thought that a little way down the ravine I saw something like a wolf. It seemed to change its position a little several times, but remained too long in one place to be a wolf. I was considering going into the dugout to get the field-glasses but had not yet moved when suddenly a streak of fire, rocket-like, shot up from the object I had been looking at, described a graceful curve, and struck in the hay a few feet from me. It was a fire-arrow shot by an Indian, to set fire to the haystack. The Indian could not have known that I was lying in the hay but thought that by firing it he would draw me out of the dugout and in the light of the fire would get a good shot at me.
