For the first one hundred miles, the soil deteriorated in quality, and the sage-bush made its appearance, as did also the "Adam's needle" or "Spanish bayonet." The latter makes an excellent substitute for soup, but a wretched cushion to alight upon when thrown from your horse. (I make the latter statement on the authority of Doctor Pythagoras.) Brackish water was found at intervals, and white saline crystallizations were seen along some of the streams. Although the soil was more sandy than further east, the buffalo grass was abundant and nutritious, so that at no time had we any difficulty in finding grazing for our cattle, and the antelope that we killed were invariably in good condition. This belt of eastern Colorado proved particularly rich in fossil wealth, to the description of which we shall devote most of this chapter, and the whole of that following. In the vicinity of the Big Sandy, we found numerous lakes of clear water, surrounded by rich pasturage.

About one hundred miles west of the Kansas line, the country began gradually improving, and continued to do so until we reached the mountains. The Bijou basin, through which we passed, afforded excellent range, and contained good streams. The country swarmed with antelopes, and once we saw a herd running rapidly, which was four minutes in crossing the road.

We had fine views of Pike's Peak, at a distance of one hundred and fifty miles, the atmosphere there being remarkably pure and transparent. Emigrants have often been deceived when, as their wagons crawled over the crest which we named First View, the fine old Peak burst upon their sight, and in their enthusiasm resolved to get an early start next day and reach it before another night-fall. Our guide told us that when he first crossed the plains, by the Platte route, his party camped for the night near Monument Rock. After supper, two of the men and a woman set out to cut their names in the stone, supposing it to be only a mile or so distant, but when an hour's traveling brought the rock apparently no nearer, they became discouraged and returned. Next day Monument Rock was found to be twelve miles distant from their camping-place.

When within a day's journey of the mountains, we came in sight of several tall objects standing out in bold relief upon the plain. These proved to be giant pines, thrown out, like sentinels, from the forests still far beyond and invisible. We could not resist the impulse to give the first one we came to a hearty hug; for, after so many weeks upon the treeless plain, these suggestions of mighty forests, with their mingled sheen and shadow, were indeed welcome. The mountains of Colorado, with their beautiful parks and wonderful young cities, have been so often described that our notes would prove a useless addition to a somewhat worn history, and hence we forbear taxing the reader's patience by transcribing them here.

After studying the principles of mining and irrigation, we spent in the neighborhood of one calendar month in getting views of sunrise and sunset, from all the known peaks, to the end that no future tourist might feel called upon to extend to us his kind commiseration for having lost some particular outlook, where he had been, and which he considered the best of all. To accomplish this thoroughly, we hewed paths up hitherto inaccessible mountains, and at the end of the month made a close calculation, and decided that we were a match for all such tourists for at least five years to come. We then retraced our steps to Buffalo Land, again entering the fossil belt near Fort Wallace.

One incident of our trip into Colorado deserves especial mention from having been the first, as it will probably prove the last, attempt to photograph the buffalo in his native wildness, at close quarters. The idea was suggested in a letter which the Professor received from his Eastern friends, who thought that actual photographs of the animals inhabiting the plains would be a valuable addition to the ordinary facilities for the study of natural history. As good fortune would have it, there happened to be at Sheridan an artist, just arrived from Hays, then prospecting for a location, and him we promptly engaged. The second day out, two old buffaloes, near our road, were selected as good subjects for first views. One of these was soon killed, the other making his escape up a ravine near by. Although we had good reason to suspect that the latter had been wounded, we did not pursue him, since it was now near noon, and our artist, moreover, being of a somewhat timid disposition, had expressly stipulated that we should keep near him, not so much, he repeatedly assured us, as a body-guard for himself, as for the protection of his new camera and outfit.

The dead bull we propped into position with our guns and other supports, and while the artist carefully adjusted his instrument, Shamus began to make preparations for lunch, and Mr. Colon and Semi set out for a few minutes' pastime in catching bugs. They had been gone a full half hour, and we were just remarking their prolonged absence somewhat impatiently, when a loud cry from the nearer bank of the ravine fell on our ears, and looking around we beheld Colon senior, and ditto junior, making toward us at a tremendous rate of speed.

"Buffalo!" was all that we could catch of Semi's wild shouts, as he led the chase directly toward us, his father having lost several seconds in securing one of his specimen-cases, and on the instant the old bull that we had wounded an hour before hove in sight, in full charge upon the flying entomologists. As buffalo charges are short ones, he would have stopped, no doubt, in a moment or so, had not Muggs and I, the only members of our party who happened to have their guns at hand, opened fire on him, and planted another bullet between his ribs. The effect was to infuriate the old fellow tenfold, and down he came careering toward us, with what I then thought the most vicious expression of countenance I had ever seen on a buffalo's physiognomy.

The attack was so sudden, and the surprise so complete, that we were most ingloriously stampeded, and fell back in hot haste upon our reserves, the guide and teamsters, who, we knew, would be provided with weapons and in good shape to cover our retreat. The sitting for which we had made such elaborate preparations was abruptly terminated in the manner shown in the accompanying engraving.

Fortunately for the artist, the blow originally intended for him was delivered upon the legs of the instrument. His assailant being at length dispatched, the poor fellow proceeded to pick out of the ruins of his property what remained that might again be useful. He stated that his stock, as well as the subject of buffalo photographing, was "rather mixed," and that, if we would pay him for the damage done, he would return. Next morning he left us, and thus it was that science lost the projected series of valuable photographic views.
