Outfitting at Jocko we rode across the divide to the St. Ignacio Mission. Less wild than the Cheyenne reservation the Flat Head country was much more beautiful, and we were entirely happy in our camp beside the rushing stream which came down from the Jocko Lakes. "Yes, there is such a herd," the trader said. "It is owned by Michel Pablo and consists of about two hundred, old and young. They can be reached by riding straight north for some twenty miles and then turning to the west. You will have to hunt them, however; they are not in a corral. They are feeding just as they used to do. They come and go as they happen to feel the need of food or water." With these stimulating directions we set forth one morning to "hunt a herd of buffalo," excited as a couple of boys, eager as hunters yet with only the desire to see the wild kine. After we left the road and turned westward our way led athwart low hills and snake-like ravines and along deep-worn cattle paths leading to water holes. All was magnificently primeval. No mark of plow or spade, no planted stake or post assailed our eyes. We were deep in the land of the bison at last. Finally, as we topped a long, low swell, my brother shouted, "Buffalo!" and looking where he pointed, I detected through the heated haze of the midday plain, certain vague, unfamiliar forms which hinted at the prehistoric past. They were not cows or horses, that was evident. Here and there purple-black bodies loomed, while close beside them other smaller objects gave off a singular and striking contrast. There was no mistaking the character of these animals. They were bison. To ride down upon them thus, in the silence and heat of that uninhabited valley, was to realize in every detail, a phase of the old-time life of the plains. We moved in silence. The grass-hoppers springing with clapping buzz before our horses' feet gave out the only sound. No other living thing uttered voice. Nothing moved save our ponies and those distant monstrous kine whose presence filled us with the same emotion which had burned in the hearts of our pioneer ancestors. As we drew nearer, clouds of dust arose like lazy smoke from smoldering fires, curtains which concealed some mighty bull tossing the powdery earth with giant hoof. The cows seeing our approach, began to shift and change. The bulls did not hurry, on the contrary, they fell to the rear and grimly halted our advance. Towers of alkali dust, hot and white, lingering smoke-like in the air shielded us like a screen, and so--slowly riding--we drew near enough to perceive the calves and hear the mutter of the cows as they reenacted for us the life of the vanished millions of their kind.
