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. [Illustration: JAIL ROCK AND COURT HOUSE ROCK]
