I have myself generally coursed with scratch packs, including perhaps a couple of greyhounds, a wire-haired deer-hound, and two or three long legged mongrels. However, we generally had at least one very fast and savage dog—a strike dog—in each pack, and the others were of assistance in turning the game, sometimes in tiring it, and usually in helping to finish it at the worry. With such packs I have had many a wildly exciting ride over the great grassy plains lying near the Little Missouri and the Knife and Heart Rivers. Usually our proceedings on such a hunt were perfectly simple. We started on horseback and when reaching favorable ground beat across it in a long scattered line of men and dogs. Anything that we put up, from a fox to a coyote or a prong-buck, was fair game, and was instantly followed at full speed. The animals we most frequently killed were jack-rabbits. They always gave good runs, though like other game they differed much individually in speed. The foxes did not run so well, and whether they were the little swift, or the big red prairie fox, they were speedily snapped up if the dogs had a fair showing. Once our dogs roused a blacktail buck close up out of the brush coulie where the ground was moderately smooth, and after a headlong chase of a mile they ran into him, threw him, and killed him before he could rise. (His stiff-legged bounds sent him along at a tremendous pace at first, but he seemed to tire rather easily.) On two or three occasions we killed whitetail deer, and several times antelope. Usually, however, the antelopes escaped. The bucks sometimes made a good fight, but generally they were seized while running, some dogs catching by the throat, others by the shoulders, and others again by the flank just in front of the hind-leg. Wherever the hold was obtained, if the dog made his spring cleverly, the buck was sure to come down with a crash, and if the other dogs were anywhere near he was probably killed
