During the journey with horses I had generally found the bag too warm, and had for the most part slept on it, not in it; but now its time was about to begin, and this night in the pine-bluff was to record a signal triumph for the sack principle applied to shake-downs.
About three o’clock in the morning the men got up, unable to sleep on account of the cold, and set the fire going.

Oh, how biting cold it was! On in the grey snow light with a terrible
