It was Boone who brought me the weapon, and the burned horse was quickly put out of its misery; but a portion of the roof fell in as I ran towards the other. This one lay still, and, I saw, recognized me. It had carried me gallantly on many a weary ride, and was the one on which Lucille Haldane had leaped across the fence. I felt like a murderer when it turned its eyes on me with an almost human appeal, for all that I could do was to press the deadly muzzle against its head. The shock of the detonation shook down a shower of blazing fragments, and I had turned away with a horrible sense of guilt, when somebody shouted, "There's a man in the end stall!"

The stall was hidden by the smoke, but, now that the emptied stable was quieter, a voice reached us faintly through the vapor: "Won't anyone take me out of this?"

Several of us made a rush in that direction; but, so far as memory serves, only Boone and I reached the stall, and, groping around it blindly, came upon something which resembled a human form. We lifted it between us, and the man both groaned and swore; then, staggering through the vapor, we came, blackened, burned a little, and half-asphyxiated, into the open. The rest were already outside, and, when we laid down our burden, they stood about him, panting.

"You've nearly killed me between you, boys, but it wasn't your fault," he gasped. "Horse fell over me when I tried to turn him loose." The half-articulate words which followed suspiciously suggested that the sufferer was cursing somebody, and I caught the name of Lane before he lapsed into semi-consciousness.

"It's pretty simple," one of the onlookers said. "The way Ormesby fixed that door, it shut itself. He got some bones smashed, and was turned half-silly by the shock. Couldn't make us hear him even if he had sense enough. My place is the nearest, and I'll take him along."

I heard my name called softly, and saw Boone standing apart from the rest. "I want to ask why you spoke as you did a little while ago?" he said.

"I did not stop to reflect just then, but I'll hear your explanation if you care to volunteer one before I apologize," I said.

"I was camped under a bluff with the wagon when I saw the blaze, and as the distance was not great, I came in on foot," was the answer. "That is the simple truth. Do you believe it?"

"Yes," I said, for his manner impressed me. "In turn, you also hinted something."

"I was giving you a warning," said Boone. "You are dealing with a dangerous man, and can't you see that if there is any doubt concerning the fire's origin a charge might be worked up against you? Be careful what you say; but as I see the sergeant yonder, you need not mention my presence unless it is necessary."
