deep, wide pathway or gully worn by the hoofs of the buffaloes, and leading down to the bottom of the ravine. With a wild shout of joy we dashed down, and soon man, horse, and dog were regaling themselves at these delicious fountains of Nature. "Kettles were swung, and in a few minuted the fragrant coffee, and boiling pemmican (dried buffalo beef, pounded) saluted our nostrils and whetted our appetites. All were busy, some unloading mules, others gathering fuel--the dried droppings of the buffalo, the only fuel of the plain, burning like turf. As we finished our meal, night was coming on, and Ben had advised us all to prepare for rest, when a low, rumbling sound, like distant thunder, started us all to our feet. As the sky was clear overhead, we were at a loss to account for the strange noise, until Ben, throwing his ear to the ground shouted,-- "`Buffaloes! Mount!' "The order was scarcely delivered before every man was in his saddle, and following Ben up the gully at full speed. On reaching the plain we had not long before crossed, a terrific sight to novices in prairie-life broke upon our vision. "Away in the distance was a great brown mass, undulating like a sea, and extending miles in each direction. A cloud of dust hung above the mighty herd of buffaloes, darkening the sky. Already they snuffed the water, and were approaching at full speed. A glance was enough for Ben. Wheeling his horse again into the ravine, he shouted for all to follow. His practised eye saw that they were making for the water-course, and in a few moments, if we remained, we should be trampled to death. "I thought that the hurried manner in which Ben ordered us to re-pack the mules and run up the ravine had something of cowardice in it. It would have been well for me had I partaken of this fear. While my more sensible companions hastened after Ben up the bottom of the ravine, I spurred my horse up the steep path to have another look--I even thought of bagging a few buffaloes, to astonish old Ben. When I reached the level of the plain, I witnessed such a sight as I shall never forget--a moving wall of life! and, within a few yards of me, grizzly, shaggy monsters, with heads to the ground, and tails erect, bellowing like an earthquake, throwing white froth from their parched mouths, while their tread seemed to shake the very earth. With a sudden start my horse reared, twisting round upon his haunches, and, wheeling round, he dashed down the pathway; and, before I could regain my presence of mind, he was galloping at the top of his speed down the ravine, in a contrary direction to that taken by my comrades, who were now out of sight. For nearly a mile he held his headlong course, until a turn in the channel brought me in sight of a new danger.
