lake; twice or thrice the distant roars of the panthers showed that these terrible animals were quitting our neighbourhood, and the fierce growling of the contending wolves told us plainly that, if they were not strong enough to run, they could at least crawl and prey upon their own dead.  It has been asserted that wolves do not prey upon their own species, but it is a mistake, for I have often seen them attacking, tearing, and eating each other.

The warm rays of the morning sun at last dispersed the gloom and clouds of night; deer, elks, and antelopes were all gone except my own stag, to which I gave a handful of salt, as I had some in my saddle-bags.  Some few mustangs and buffaloes were grazing, but the larger portion, extending as far as the eye could reach, were still prostrate on the grass.  As to the wolves, either from their greater fatigue they had undergone, or from their being glutted with the blood and flesh of their companions, they seemed stiffer than ever.  We watered our horses, replenished our flasks, and, after a hearty meal upon the cold flesh of the bear, we resumed our journey to warm ourselves by exercise and dry our clothes, for we were wet to the skin, and benumbed with cold.

The reader may be surprised at these wild animals being in the state of utter exhaustion which I have described; but he must be reminded that, in all probability, this prairie fire had driven them before it for hundreds of miles, and that at a speed unusual to them, and which nothing but a panic could have produced.  I think it very probable that the fire ran over an extent of five hundred miles; and my reason for so estimating it is, the exhausted state of the carnivorous animals.

A panther can pass over two hundred miles or more at full speed without great exhaustion; so would a jaguar, or, indeed an elk.

I do not mean to say that all the animals, as the buffaloes, mustangs, deer, &c., had run this distance; of course, as the fire rolled on, the animals were gradually collected, till they had formed the astounding mass which I have described, and thousands had probably already perished, long before the fire had reached the prairie where we were encamped; still I have at other times witnessed the extraordinary exertions which animals are capable of when under the influence of fear.  At one estampede, I knew some oxen, with their yokes on their necks, to accomplish sixty miles in four hours.

On another occasion, on the eastern shores of the Vermilion Sea, I witnessed an estampede, and, returning twelve days afterwards, I found the animals still lying in every direction on the prairie, although much recovered from their fatigue.  On this last occasion, the prairie had been burnt for three hundred miles, from east to west, and there is no doubt but that the animals had estampedoed the whole distance at the utmost of their speed.
