We had camped some distance from the trail, and having taken our horses over the ridge into another ravine, had picketed them on the best grass that could be found. It was my duty to stand guard and watch the horses until midnight. The night was clear and still, and although it was bright starlight, it seemed to be very dark in the ravine. I took a position slightly up the hillside and reclined with ear near the ground. About midnight there came seemingly from some very distant source, a low, deep, rumbling roar. For a time it was impossible even to surmise the cause. It seemed to be subterranean and yet it was not an earthquake, for the sound was continuous and gradually increased in depth and power. In a few minutes I became convinced that it was caused by the hoofs of a great number of running horses approaching through the ravine. As a measure of precaution I thought it best to move a little out of the valley to a position behind a growth of sage brush near-by, and there await developments. An Indian raid at midnight was hardly to be suspected, nor had we heard of any large body of cavalry in those parts. The sound increased in power like the roar of an approaching tornado, and an onrushing mass finally swept round the nearest curve in the ravine. Our horses, frightened by the approaching herd, suddenly started in advance, as could be inferred from their snorting and the rattle of the iron picket pins, some of which were pulled from the ground. All were soon in flight. Those which failed at once to escape were carried along the next moment with a solid, resistless tide of oncoming mules which leaped one upon another. As the drove swept by I caught glimpses here and there of the moving forms, which showed that the mules were riderless; being stampeded, their fright was communicated to one another—those in the rear crowding upon those in front; and some of them, I believe, stumbled and were run over by the compact mass that followed. In a moment all had passed; but for a long time in the direction of a range of hills to the west, could be heard the roar of hundreds of hoofs and the ring of the picket pins as they were dragged over the stony ground. The sound did not die away entirely in its slow diminuendo until the mules had passed the range six miles to the west. On visiting the spot where our horses had been picketed, we found that every one of them had been carried away in the mad rush, and unless we could recover them the inconveniences would be most serious. The natural conclusion then was that the large herd had been stampeded by mounted Indians, who would soon follow.

When about to return to camp to report the situation to our party, I became conscious of the approach of mounted men from the same direction as that from which the stampede came.

I soon heard their voices. They proved to be four men on horseback, who (I then suspected) might have caused the rush. Myself a party to the loss of stock, and believing it to be my duty quickly to summon our party, I fired my rifle in advance of the riders. Wishing to make myself appear as numerous as possible, I repeated the challenge with two or three additional shots in rapid succession, and with as firm a voice as I could command called to the riders to halt. To my surprise they did halt. One of the men gruffly asked, "Who are you?" Another shouted what seemed rather an incoherent declaration, the tenor of which as I caught it, was in effect that I was shooting at the United States Government. Perhaps it was the darkness and the fact that I was out of their reach that inspired me with sufficient confidence to order them not to proceed further until we could ascertain who they were. The pronoun "we" was used not only to emphasize the authority of the speaker and thereby command respect, but also on the theory that the more numerous I could make myself appear the safer I was likely to be until our boys should arrive in response to the rifle call. As was expected, our men rounded up very quickly, for our campers were not compelled to dress and make an elaborate toilet on receiving a call. A mutual investigation followed, through which we learned that a Government train of which we had no previous knowledge had camped three miles northwest of our trail, and their stock, about 240 in number, had been stampeded through the carelessness or folly of one their own drivers; and the animals were away before their men were prepared to start in pursuit. They had been able to find a few saddle horses which had been picketed and had not escaped in the panic. On being informed very definitely concerning the direction which the flying herd had taken, the riders, after giving the assurance that all of our horses would in time doubtless be returned, started on their hunt. After daybreak they encountered no difficulty in following their course, which was well marked by hoof tracks; and in the forenoon all of our horses were once more at our command, but none the better for their escapade.

This Lodge Pole Creek ford became of some interest to overland travelers by reason of the fact that some years later the old Oregon trail, which we were still pursuing, was here crossed by the Union Pacific Railroad, which up to this point along much of its course was built exactly upon the trail marked by the first Mormon emigrants in 1847, following many of its windings. This fact suggests a striking comparison between the early and the later modes of travel. Our party, moving as steadily as possible, had consumed twenty-five days in reaching this point from the Missouri River. Ben Holliday's stages, when they followed the route that we were taking, reached Lodge Pole on the fifth day, being driven continuously night and day with relays of horses every ten or fifteen miles. It is now reached in twelve hours by express trains.

Our next day's journey after leaving Pole Creek was over a series of ridges along an excellent roadway the great part of the distance. The highest points disclosed fine views of the rocky cliffs along the North Platte. There is a marked change in the general features of the country as compared with those seen along the Platte valley east of Julesburg. The road showed that it had been traveled but little. We were able to make a drive of twenty-eight miles, reaching Mud Spring in the evening. Why this tiny fountain should be so denominated is unknown and unknowable; it was the first clear, living water that we had seen west of the Missouri River, except in a few wells at stage stations. In February of the preceding year this spot was the scene of some sharp fights with the Indians.

And now there lay immediately before us the longest and most difficult drive of the trip, concerning which we had secured much information. It would conduct us across a wide stretch of sandy desert in which there was no pasturage; and forty long miles must be laid behind in order to reach a camp ground where there was any grazing whatever for horses. The preceding day had been intensely hot, and there were no indications of any immediate change in the temperature. To secure the benefit of the cooler early hours we were off at exactly three o'clock in the morning. Near where we entered the dreary waste of sand we parallelled for a short distance a small stream, concerning which we had been advised that it was the only desirable place for lunch. We had prepared some cold boiled beans, bacon and coffee, which we pulled from the mess box, and as the rays of the sun had now become very oppressive, we prepared to drop down upon the hot sand in the shade of a wagon. The Deacon protected himself somewhat from the sands by sitting upon a rolled-up blanket. Others remained standing or dropped upon their knees, but Pete remarked that as the tallest and largest man in the party he was fairly entitled to a certain high mound of sand of convenient shape, which he found well in the shade. These piles were formed by some little clumps of grease wood, or similar growth, which the sand had drifted round and in many cases entirely covered, as a little obstruction will sometimes collect a small snow drift.

Pete, who was a tall, powerful, but rather slow-moving individual, dropped wearily and heavily upon the sand heap which he proposed to occupy by right of squatter sovereignty. Although it was a long distance from the seat of Pete's "pants" to the seat of his intelligence, yet the information was quickly transmitted to his brain that something was under him that was not all sand. With a sudden yell, as if stung by a serpent, he leaped into the air with agility and enthusiasm of which he had hitherto been deemed altogether incapable. Peter swore. He then inspected the sand pile, while we watched him with dismay, being ignorant of the cause of his frenzy. Reaching out at arm's length, he cautiously poked the mound with his whip stock and found, not a rattlesnake, but only an oval-shaped cactus slightly concealed beneath the sand. Its long spines as sharp as needles and almost uncountable in number, under the weight of Pete's body had penetrated his flesh no one yet knows how far. As the punctured parts could not easily be examined by the sufferer, his companion, Noah, performed the operation of removing such of the needles as were visible. Many without doubt remained, for during the next two or three days Peter walked with short steps, staccato, and rarely indulged in a sitting posture.

JAIL ROCK AND COURT HOUSE ROCK

The stream near which we had halted afforded the last opportunity to obtain water until we should complete the long drive across the sands. Our horses were fed with fine wheat flour, the only nourishment which we could secure to stay them through the day. After having filled the water kegs and canteens from the stream, the difficult march was continued. The day was so intensely hot that nearly all members of the party walked to relieve the perspiring horses. The country we were traversing was an area of loose, dry sand. Its surface was marked by small mounds and ridges of sand, the ridges all trending in one direction and evidently drifted with the prevailing wind behind a clump of stunted grease wood, a small shrub which grows on alkaline soils and, like other desert growths, is stiff and stubby,—possibly a provision of nature to preserve its scant foliage from being browsed; shrubs so protected remained, a survival of the fittest. Some such provision is certainly necessary to protect the plant life of the desert in its struggle for existence. The surface of the sand was slightly hardened by a thin scale, possibly due to solidification in drying, after a passing shower had moistened the salts in the sand. The scale in many places prevented the wheels from sinking deeply. The wagons were, therefore, scattered along side by side, because a track once followed was deeply cut in the ruts. Numerous lizards (swifts) glided along the parched surface of the Sahara and were the only specimens of animal life that I observed there with any interest.
