Tired out at length, the old bull begins to totter, and his knees to shake from sheer exhaustion. His shakiness is as fatal as that of a Wall Street bull. As he lies down the wolves are upon him. They are clinging to the shaggy form, like blood-hounds, before it has even sunk to the sod, and the victim never rises again.

The cayotes are very cowardly, and when carcasses are plenty, sleep during the day in their holes, which are generally dug into the sides of some ravine. If found during the hours of light, it is usually skulking in the hollows near their burrows. They have a decidedly disagreeable penchant for serenading travelers' camps at night, so that our late experience, the guide assured me, was by no means uncommon. They will steal in from all directions, and sit quietly down on their haunches in a circle of investment. Not a sound or sign of their coming do they make, and, if on guard, one may imagine that every foot of the country immediately surrounding is visible, and utterly devoid of any animate object. All at once, as if their tails were connected by a telegraphic wire, and they had all been set going by electricity, the whole line gives voice. The initial note is the only one agreed upon. After striking that in concert, each particular cayote goes it on his own account, and the effect is so diabolical that I could readily excuse Shamus for thinking that the dismal pit had opened.

At this point Dobeen approached and cut off my further gleaning of wolf lore. The corners of his mouth seemed still inclined to twitch, showing that the shock had not yet worn off. He was chilled by the night, he said, and did not feel very well, and craved our honors' permission to sleep at our feet in the tent. Consent was given, and as he left us he turned to announce his belief that animals with such voices must have big throats.

It was not yet light, next morning, when our camp was all astir again. Drowsiness has no abiding place with an expedition like ours upon the plains. Should he be found lurking anywhere among the blankets, a bucket of water, from some hand, routs him at once and for the whole trip. Even Sachem, who usually hugged Morpheus so long and late, might that morning have been seen among the earliest of us washing in the waters of the creek.

We were all in excellent spirits, and with appetites for breakfast that would have done no discredit to a pack of hungry wolves. No sign of the sun was yet visible, save a scarcely perceptible grayish tinge diffusing itself slowly through the darkness, and the lifting of a light fog along the creek upon which we were encamped. Although sufficiently novel to most of our party, the scene was quite dreary, and we longed, amid the gloom and chill, for the appearance of the sun, and breakfast. By the way, I have noticed that with excursion parties, whether sporting or scientific, enthusiasm rises and sets with the sun. The gray period between darkness and dawn is an excellent time for holding council. The mind, no less than the body, seems to find it the coolest hour of the twenty-four, and shrinks back from uncertain advances.

Added to the discomforts usually attendant upon camp-life were our stiff joints. The first day upon horseback is twelve hours of pleasant excitement, with a fair share of wonder that so delightful a recreation is not indulged in more generally. The next twenty-four hours are spent in wondering whether those limbs which furnish one the means of locomotion are still connected with the stiffened body, or utterly riven from it; and, if the whole truth must be told, the saddle has also left its scars.

As the edge of the plateau overlooking the river became visible in the growing light, we saw, as on the evening previous, multitudes of buffalo feeding there, and after breakfast a council of war was held. I am somewhat ashamed to record that it voted no hunting that day. To find the noblest of American game some of us had come half away across the continent, and now, in sight of it, the tide of enthusiasm which had swept us forward hitherto stood suddenly still. Not because it was about to ebb, but simply in obedience to certain signals of distress flying from the various barks, and which it was utterly impossible for any of us to conceal.

For mounting a horse was entirely out of the question for that day. Not one of us could have swung himself into saddle for any less motive than a race with death. Our steps were slow and painful, and we felt as if, at this period of life's voyage, every timber of our several crafts had been pounded separately upon some of the hidden rocks of ocean. It was absolutely necessary to go into dock for repairs, and the valley promised to be a pleasant harbor.

It was a truly melancholy spectacle to behold Sachem and Muggs. The liveliest and the gayest ones yesterday, but to-day the gravest of the grave. That rotund form, which always doubted his own or other people's emotions, was the walking embodiment of woe, and for once evidently clear of all doubt upon one subject, at least. Muggs was even free to confess that, for general results, yesterday's rough riding exceeded "a 'unt with the 'ounds." Our animals were also quite stiff, but the hostlers attributed this not so much to their yesterday's service as to their long ride in the cars. They had not yet got their "land legs" fully on again. It was soothing to our pride, if not to our feelings, to reflect that perhaps some of our soreness was the result of their first day's stiffness.

A beaver colony near us, and a great abundance of turkeys, offered lessons in natural history of no small interest, and within reach of lame students. The valley gave an entomological invitation to Mr. Colon, and the great ledges, with their possibilities of valuable fossils, attracted the Professor.
