One was to be awake all night as guard; though, of course, all took turns, each awaking the sentinel whose watch was to follow his.

To the doctor was assigned the first two hours, and as we went to sleep, we could perceive his plump rounded form seated upon the outer rim of the circular bank above us. None of us had any great faith in the doctor as a guard, but his watch was during the least dangerous time of night, so far as Indians are concerned. These never make their attack until the hours after midnight, as they know well that these are the hours of soundest sleep. The horse-drive of the previous night was an exception, but that had happened because they had drawn near and seen no horse-guard. It was a very unusual case. They knew that we were now on the alert; and if they had meditated farther mischief, would have attempted it only after midnight hour. We had no apprehensions therefore, and one and all of us being very much fatigued with the day’s hunting afoot, slept soundly. The bank against which we rested was dry and comfortable; the fire warmed us well, and redoubled our desire for repose.

It appears that the doctor fell asleep on his post, or else we might all of us have been better prepared for the invasion that we suffered during that night.

I was awakened by loud shouts—the guides were uttering them. I sprang to my feet in the full belief that we were attacked by Indians, and at first thought caught hold of my gun. All my companions were roused about the same time, and, labouring under a similar hallucination, went through a like series of manoeuvres.

But when we looked up, and beheld the doctor stretched along the ridge, and still snoring soundly, we scarce knew what to make of it.

Ike and Redwood, however, accustomed to sleep with one eye open, had waked first, and had already climbed the ridge; and the double report of their guns confirmed our suspicions that we were attacked by Indians. What else could they be firing at?

“This way all of you!” cried Redwood, making signs for us to come up where he and his companion already were, waving their guns around their heads, and acting in a very singular manner, “this way, bring your guns, pistols, and all—quick with you!”

We all dashed up the steep, just at the moment that the doctor suddenly awaking ran terrified down. As we pressed up, we could hear a mingling of noises, the tramp of horsemen as we thought, and a loud bellowing, as if from a hundred bulls. The last sounds could not well have been more like the bellowing of bulls, for in reality it was such. The night was a bright moonlight, and the moment we raised our heads above the scarp of the ridge we saw at once the cause of our alarm. The plain around us was black with buffaloes! Tens of thousands must have been in the drove which was passing us to a great depth on both sides. They were running at a fast trot—some of them even galloping, and in some places they were so thickly packed together, that one would be seen mounting upon the hind-quarters of the other, while some were thrown down, and trampled over by their companions.

“Hyur, hyur, all of ye!” cried Ike, “stand by hyur, or they’ll git into the hole, and tramp us to shucks!”

We saw at a glance the meaning of these instructions. The excited animals were rushing headlong, and nothing seemed to stay their course. We could see them dashing into and across the little streamlet without making any account of it. Should they pour into the circle in which we stood, others would follow, and we might get mingled with the drove. There was not a spot on the prairie where we could have been safe. The impetuous mass was impelled from behind, and could neither halt nor change its course. Already a pair of bulls had fallen before the rifles of our guides, and to some extent prevented the others from breaking over the ring, but they would certainly have done so had it not been for the shouts and gestures of the trappers. We rushed to the side indicated, and each of us prepared to fire, but some of the more prudent held their loads for a while, others pulled trigger, and a succession of shots from rifles, double-barrels, and revolvers soon raised a pile of dead buffaloes that blocked up the passage of the rest, as though it had been a barrier built on purpose.
