They stopped at a half dozen ranches, terrorizing and burning, but catching no horse-thieves. It is impossible through the obscurity that shrouds the grim events of that autumn to determine to what extent they were honestly in pursuit of lawbreakers or were merely endeavoring, at the behest of some of the great cattle-owners, to drive the small stockmen out of the country. Their motives were possibly mixed. The small ranchers were notoriously not always what they seemed. Most of the horse-thieves posed as "nesters," hiding in underground stables by day the horses they stole by night. Each registered his own brand and sometimes more than one; but the brands were carefully contrived. If you intended, for instance, to prey on the great herds of the "Long X outfit," thus [X brand], you called your brand "Four Diamonds," marking it thus [diamond brand]. A quick fire and a running iron did the trick. It was all very simple and very profitable and if you were caught there was always a Certain Person (to whom you were accustomed to give an accounting), and beyond him a vague but powerful Somebody Else to stand between you and the law. There would be no trial, or, if there were a trial, there would be no witnesses, or, if there were witnesses, there would be a lenient judge and a skeptical jury. The methods of Flopping Bill's party were no doubt reprehensible, but in attacking some of the little "nesters" the raiders came close to the heart of many troubles. But indiscriminate terrorizing by any one in any cause was not to the taste of the ranchmen up and down the Little Missouri who happened to be law-abiding. The raiders were starting prairie fires, moreover, with the purpose evidently of destroying the pasture of the small stockmen, and were in consequence vitally affecting the interests of every man who owned cattle anywhere in the valley. That these acts of vandalism were the work of a body from another Territory, invading the Bad Lands for purposes of reform, did not add greatly to their popularity. The ranchmen set about to organize a vigilance committee of their own to repel the invaders, if necessary, by force. Whether the raiders got wind of this purpose is not known, but they evidently decided that they had overplayed their hand, for they suddenly veered in their course and troubled the Bad Lands no more. But before they went they dropped a bomb which did more than many conflagrations to carry out their ostensible mission as discouragers of evil-doing.
