Under the circumstances, this was the most brilliant piece of work of the entire hunt. As the four cows dashed past the hunters at the Buffalo Buttes, heading for the High Divide, fully 20 miles distant, McNaney killed one cow, and two others went off wounded. Of course the cowboys gave chase. About 12 miles from the starting-point one of the wounded cows left her companions, was headed off by Boyd, and killed. About 6 miles beyond that one, McNaney overhauled the third cow and killed her, but the fourth one got away for a short time. While McNaney skinned the third cow and dressed the carcass to preserve the meat, Boyd took their now thoroughly exhausted horses to camp and procured fresh mounts. On returning to McNaney they set out in pursuit of the fourth cow, chased her across the High Divide, within a mile or so of our camp, and into the ravines on the northern slope, where she was killed. She met her death nearly if not quite 25 miles from the spot where the first one fell. The death of these four cows brought our number of buffaloes up to eighteen, and made us think about the possibilities of getting thirty. As we were proceeding to the Buffalo Buttes on the day after the "kill" to gather in the spoil, Mr. Brown and I taking charge of the wagon, Messrs. McNaney and Boyd went ahead in order to hunt. When within about 5 miles of the Buttes we came unexpectedly upon our companions, down in a hollow, busily engaged in skinning another old cow, which they had discovered traveling across the bad grounds, waylaid, and killed. We camped that night on our old ground at the Buffalo Buttes, and although we all desired to remain a day or two and hunt for more buffalo, the peculiar appearance of the sky in the northwest, and the condition of the atmosphere, warned us that a change of weather was imminent. Accordingly, the following morning we decided without hesitation that it was best to get back to camp that day, and it soon proved very fortunate for us that we so decided. Feeling that by reason of my work on the specimens I had been deprived of a fair share of the chase, I arranged for Mr. Boyd to accompany the wagon on the return trip, that I might hunt through the bad lands west of the Buffalo Buttes, which I felt must contain some buffalo. Mr. Russell went northeast and Mr. McNaney accompanied me. About 4 miles from our late camp we came suddenly upon a fine old solitary bull, feeding in a hollow between two high and precipitous ridges. After a short but sharp chase I succeeded in getting a fair shot at him, and killed him with a ball which broke his left humerus and passed into his lungs. He was the only large bull killed on the entire trip by a single shot. He proved to be a very fine specimen, measuring 5 feet 6 inches in height at the shoulders. The wagon was overtaken and called back to get the skin, and while it was coming I took a complete series of measurements and sketches of him as he lay.
