13be Conservative * side for the distance of eight painful miles. After pausing to repose , and to enjoy these grand but savngo and awful scones , they began to descend the east ern side of the mountain. The descent was rugged and romantic , along deep ravines and defiles , overhung with crags and cliffs , among which they be held numbers of the ahsahta or bighorn , skipping fearlessly from rock to rock. Two of them they succeeded in bringing dowii with their rifles , as they peered fearlessly from the brow of their airy precipices. "Arrived at the foot of the mountain , the travellers found a rill of water oozing out of the earth , and resembling in look and taste the water of the Mis souri. [ It was , in fact , the Sweet- water. ] Hero they encamped for the night , and supped sumptuously upon their mountain mutton , which they found in good condition and extremely well tasted. "Tho weather was now so severe , and the hardships of travelling so greatthat ho resolved to halt for the winter at the first eligible place. That night they had to encamp on the open prairie , near a scanty pool of water , and without any wood to make a fire. The northeast wind blow keenly across the naked waste , and they were fain to decamp from their inhospitable bivouac before the dawn. * * * * * "Lato on the afternoon of the 80th , they came to whore the stream , now in creased to a considerable size , poured along in a ravine between precipices of red stone two hundred feet in height. For some distance it dashed along , over huge masses of rock , with foaming violence lence , as if exasperated by being com pressed into so narrow a channel , and at length leaped down a chasm that looked dark and frightful in the gather ing twilight. "For a part of the next day , the wild river , in its capricious wanderings , led them through a variety of striking scenes. At one time they would be upon high plains , like platforms among the mountains , with herds of buffaloes roaming about them ; at anothernnioug rude , rocky defiles , broken into cliffs and precipices , where the black-tailed deer bounded off among the crags , and the bighorn basked on the sunny brow of the precipice. "In the after part of the day , they came to another scone , surpassing in savage grandeur those already de scribed. They had been travelling for some distance through a pass of the mountains , keeping parallel with the river , as it roamed along , out of sight , through a deep ravine. Sometimes their devious path approached the margin - gin of the cliffs below which the rivoi foamed and boiled , and whirled among the masses of rock that had fallen into its channels. As they crept cautiously ' ; .VK * KK' . \ on , leading their solitary paok-horso , along thcso giddy heights , they all at once came to where the river thundered down a succession of precipices , throw ing up clouds of spray , and making a prodigious din and uproar. The travel lers remained , for a time , gazing with mingled awe and delight at this furious cataract , to which Mr. Stuart gave , from the coloring of the impending rocks , the name of "Tho Fiery Nar rows. " * * * * * The first chasm was probably the Devil's Gate on the Sweotwator , ouco a famous landmark , now merely an inci dent of a ranchman's back pasture , and dammed for peaceful irrigation. The second , Captain Ohittoudon says , was the Upper Platte Canon. Hero they became totally lost. From the course of the Platte at this point they concluded that it could not be a branch of that river ; they thought it must be the Cheyenne or Niobrara , and they de cided to camp for the winter. Another Indian scare dislodged them again however , and in the middle of Decem ber they moved a considerable distance further down the North Platte. Com ing into the range country about Deuel county , Nebraska , they were appalled at the emptiness of the landscape and turned upstream again for three days , when they pitched their final winter camp ; which Ohittenden locates near Wellesville , Cheyenne county. "The winter passed away without any Indian visitors , and the game con tinued to be plenty in the neighborhood. They foiled two large trees , and shaped them into canoes ; and , as the spring opened , and a thaw of several days' continuance melted the ice in the river , they made every preparation for em barking. On the 8th of March they launched forth in their canoes , but soon found that the river had not depth suf ficient even for such slender barks. It expanded into a wide but extremely shallow stream , with many sand-bars , and occasionally various channels. They got one of their canoes a few miles down it , with extreme difficulty , sometimes wading , and dragging it over the shoals ; at length they had to abandon the at tempt , and to resume their journey on foot , aided by their faithful old packhorse - horse , who had recruited strength dur ing the repose of the winter. "Tho weather delayed thorn for a few days , having suddenly become moro rigorous than it had been at any time during the winter ; but on the 20th of March they wore again on their journey. "In two days they arrived at the vast naked prairie , the wintry aspect of which had caused them , in Do- conibor , to pause and turn back. It was now clothed in the early verdure of spring , and plentifully stocked with game. Still , when obliged to bivouac on its bare surface , without A' any shelter , and by a scanty lire of dry buffalo dung , they found the night blast piercing cold. On one occasion , a herd of buffalo straying near their evening camp , they killed tJireo of them merely for their hides , wherewith to make a shelter for the night. "They continued on for upwards of a hundred miles ; with vast prairies extending before thorn as they advanced ; eomotimes diversified by undulating Jiills , but destitute of trees. In one place they saw a gaug of sixty-fivo wild horses , but as to the buffaloes , they seemed absolutely to cover the country. Wild geese abounded , ami they passed extensive swamps that wore alive with in numerable flocks of waterfowl , among which were a few swans , but an end less variety of ducks. "Tho river continued a winding course to the cast-northeast , nearly a mile in width , but too shallow to float even an empty canoo. The country spread out in a vast level plain , bounded by the horizon alone , oxjoptiug to the north , whore a line of hills scorned like a long promon tory stretching into the bosom of the ocean. The dreary sameness of the prairie wastes began to grow ex tremely irksome. The travellers longed for the sight of a forest , or grove , or single tree , to break the level uniformity , and began to notice every object , that gave reason to hope they wore drawing towards the end of this weary wilderness. Thus the occurrence of a particular kind of grass was hailed as a proof that they could not be far from the bottoms toms of the Missouri ; and they wore rejoiced at putting up several prairie lions , a kind of grouse seldom found far in the interior. In picking up drift-wood for fuel , also , they found on some pieces the mark of an axe , which caused much speculation as to the time when and the persons by whom the trees had been felled. Thus they wont on , like sailors at sea , who perceive in every floating weed and wandering bird , harbingers of the wished-for land. " This , it should bo noted , is the first precise description on record of the interior of Nebraska and the valley of the Platte. "By the close of the month the weather became very mild , and , heavily burdened as they wore , they found the noontide temperature un comfortably warm. On the SOtli , they came to three deserted hunting camps , either of Pawnees or Ottoes , about which wore buffalo skulls in all directions and the frames on which the hides had been stretched and cured. They had apparently boon occupied the preceding autumn. "For several duys they kept pa/
