When we started upon our return from the long wanderings of the day to which I have referred, we realized that a drink of cool water would have been more welcome than an antelope would have been. As our course outward had been tortuous, without any objective point in view, and had carried us possibly eight miles from camp, our knowledge of plainscraft was fully tested, for the camp was pitched in a little valley invisible from any point forty rods distant. Many of the ravines were dry runs, down which the water evidently had flowed in time of storms, but in the sides of many of them were exposed strata of alkali several feet in thickness. We finally observed in the distance the glistening of water in a broad, sandy valley and changed our course to reach it. It proved to be one of those remarkable water courses common in parts of that country, where a stream filters along beneath the dry quicksand and here and there appears for a short distance at the surface, but it would have been impossible to dip the tiniest cup of water from it, for the sand instantly refilled the slightest depression made in it. A strainer of fine cloth might possibly have prevented one from drinking sand. There was, indeed, an opportunity to moisten our lips, but wet sand is an unsatisfactory beverage at best. The water was found to be strongly alkaline, therefore unfit to quench thirst--an unpleasant disappointment on a hot day in the midst of a hot, arid plain. "Traverse the desert, and then ye can tell What treasures exist in the cold, deep well. Sink in despair on the red, parched earth, And then we may reckon what water is worth." This water famine of only eight or nine hours was comparatively a small matter, but it impressed us with the fact of our constant dependence upon the simple things of life. When we had found our camp and satisfied our thirst from the old water keg we discovered with pleasure that Paul, who went out as usual alone on horseback, had brought in an antelope, which, of course, furnished us steak for supper. Paul's success, however, was eclipsed on the following day. It was July 29th. Driving Pete's fine four-horse team in advance of the train, and while passing along the summit of an elevated ridge commanding an extended view over a broad valley on our left, I discovered a dark, moving object three or four miles distant, toward the furthest limit of that depression. The field-glass disclosed the fact that it was a solitary buffalo. The train was halted. Although tens of thousands of these magnificent animals were at close range later on my return, this was the first buffalo thus far seen on our trip that was near enough to justify the hunt. Fresh meat was needed, and every one was eager for any excitement. It was therefore determined that Ben, Fred, and Mr. Alsop, the Captain of Creighton's train, should enter the chase. Hasty preparations to that end were accordingly made.
