Somewhere, not far from his present camp, a mounted stranger dropped in late one evening. The man was riding a good horse, but was quite alone; so also was Big Bill. The camp of the skin-hunter was then the same in appearance as when I saw him and his partner Bob Stewart--simplicity itself; a long spruce pole was lashed at either end to two spruce firs; against this, leaning at an angle of about 45 degrees, were sixty or seventy straight poles laid close together, and upon these were arranged spruce boughs to form a thatch. This lean-to provided a tolerable shelter within the forest, when the wind was sufficiently considerate to blow at the back against the thatch, instead of direct towards the open face. The ground in the acute angle was strewed with branches of spruce, and a large fire was kept burning during night, exactly in front, the whole arrangement exhibiting the principle of a Dutch oven. In such a camp, Big Bill received the stranger with the hospitality of the wilderness, and they laid themselves down to rest in the close companionship of newly-made friends. The morning broke, and as Big Bill rubbed his eyes with mute astonishment, he could not see his friend. He rose from his sleeping-place, and went outside in the cold morning air; he could not see his horses. A horrible suspicion seized upon him; he searched the immediate neighbourhood; the animals had vanished, both horses and mules were gone, together with the unknown stranger, to whom he had given food and shelter for the night. Fortunately there was a particular horse which Big Bill for special reasons kept separate from the rest; this animal was picqueted by itself among the spruce firs at some little distance, and had been unobserved by the departed stranger. To saddle the horse, and to follow in pursuit at the highest speed upon the trail of the horse-stealer, was the work of only a few minutes. The track was plain enough in the morning dew, where ten or a dozen mules and horses had brushed through the low prairie grass. Big Bill went at a gallop, and he knew that he must quickly overtake them; his only doubt lay in the suspicion that there might be confederates, and that a strong party might have joined together to secure the prize, instead of the solitary stranger being in charge. However, at all hazards he pushed on at best speed in chase; at the same time, the horse-stealer, thoroughly experienced in his profession, was driving his ill-gotten herd before him at a gentle trot, thoroughly convinced that it would be impossible to be overtaken, as the owner had been left (as he supposed) without a horse. At length, after a pursuit of some hours, upon attaining the summit of a broad eminence, Big Bill's eyes were gladdened by the sight of some distant objects moving upon the horizon, and he at once redoubled his speed.
