Before we could make any effort at capture, the elk and horses winded us and fled away toward the opposite ridges, where stalking them would have been exceedingly difficult, if not impossible. Leading the mustangs was a large black stallion, which kept its position by pacing while the others ran. Buffalo Bill said this was an escaped American horse which had fled to solitude with the rider's blood upon his saddle. We noted the statement as one for future elucidation at our camp-fire. The rabbit chase in the ravine continued, and we watched it unseen for several minutes. The wolves were endeavoring to surround their victim, and cut in ahead of it whenever he attempted to get out of the ravine. Although such odds were against him, the rabbit had thus far succeeded by superior speed and quick dodging in evading his enemies; but escape was hopeless, as he was hemmed in and becoming exhausted. These tireless wolves, cowardly creatures though they are, might worry to death an elephant. A few shots terminated this scene, driving off the wolves, but killing the rabbit for whose protection they were fired. The Professor remarked that this was like a lawyer's rescue. He sometimes frightens away the persecutors, but the charges generally kill the client. For the benefit of those of my readers who have never seen a member of that unfortunate rabbit family which has been christened by such a humiliating given name, I would state that the species is remarkable for its very long ears, and very long legs. If the reader, being a married man, desires a pictorial representation of this animal, let him draw a donkey a foot high on the wall, and if his wife does not interrupt by drawing a broomstick, he may be satisfied that his work is well done, and a life-size jackass-rabbit will stand out before him. A mile from the scene of this adventure Silver Creek joined the Saline, and at the junction it was determined to make our camp. We descended among heavy "brakes," staying our loaded wagons with ropes from behind. Immense quarries of the soft, white limestone rose from the valley's bed to the level of the plains above, and the rains of centuries had fashioned out pillars and arches, giving them the appearance of ancient ruins staring down upon us. Mr. Colon picked up a fine moss agate and the Professor a Kansas diamond. Under the surface of the former were several figures of bushes and trees, outlined as distinctly as the images one sees blown into glass. The diamond was as large as a hazel nut and as clear as a drop of pure water, so that, notwithstanding its size, ordinary print could be easily read through it. Had it possessed a hardness corresponding with its beauty, the Professor could have enriched with it half a dozen scientific institutions. Such stones now command a fair market value among travelers, and are generally mounted in rich settings as souvenirs of their trips.
