The key had been turned in the lock, but the bolt of the lock had failed to catch in the socket. It was plain that the negro thought he had locked the door, but it was quite as plain that he had been careless, and I made a resolution then and there to look after the safety of the horses myself. I swallowed more than half of my irritation when I found that the horses were in their stalls, warmly blanketed, and an abundance of food before them. I was on the point of locking the door with my own key, when I heard the sound of approaching footsteps. There were two men, civilians, as I judged, and one of them stuttered. Their conversation was of a nature to interest me.
