I shot five bobcats: two old males weighing 39 and 31 pounds respectively; and three females, weighing, respectively, 25, 21, and 18 pounds. Webb killed two, a male of 29 pounds and a female of 20; and Stewart two females, one of 22 pounds, and the other a young one of 11 pounds. I sent the cougar and bobcat skulls to Dr. Merriam, at the Biological Survey, Department of Agriculture, Washington. He wrote me as follows: “The big [cougar] skull is certainly a giant. I have compared it with the largest in our collection from British Columbia and Wyoming, and find it larger than either. It is in fact the largest skull of any member of the _Felis concolor_ group I have seen. A hasty preliminary examination indicates that the animal is quite different from the northwest coast form, but that it is the same as my horse-killer from Wyoming—_Felis hippolestes_. In typical _Felis concolor_ from Brazil the skull is lighter, the brain-case thinner and more smoothly rounded, devoid of the strongly developed sagittal crest; the under jaw straighter and lighter. “Your series of skulls from Colorado is incomparably the largest, most complete and most valuable series ever brought together from any single locality, and will be of inestimable value in determining the amount of individual variation.” [Illustration: STARTING FOR A HUNT From a photograph by Philip B. Stewart ] We rode in to the Keystone Ranch late on the evening of the second day after leaving Meeker. We had picked up a couple of bobcats on the way, and had found a cougar’s kill (or bait, as Goff called it)—a doe, almost completely eaten. The dogs puzzled for several hours over the cold trail of the cougar; but it was old, and ran hither and thither over bare ground, so that they finally lost it. The ranch was delightfully situated at the foot of high wooded hills broken by cliffs, and it was pleasant to reach the warm, comfortable log buildings, with their clean rooms, and to revel in the abundant, smoking-hot dinner, after the long, cold hours in the saddle. As everywhere else in the cattle country nowadays, a successful effort had been made to store water on the Keystone, and there were great stretches of wire fencing—two improvements entirely unknown in former days. But the foreman, William Wilson, and the two punchers or cowhands, Sabey and Collins, were of the old familiar type—skilled, fearless, hardy, hard-working, with all the intelligence and self-respect that we like to claim as typical of the American character at its best. All three carried short saddle guns when they went abroad, and killed a good many coyotes, and now and then a gray wolf. The cattle were for the most part grade Herefords, very different from the wild, slab-sided, long-horned creatures which covered the cattle country a score of years ago.
