The road became so difficult, that with the greatest exertion, we made barely fifteen miles a day. At the same time our horses began to die, being less enduring than mules and more choice of food; men failed in strength too, for during whole days they had to draw wagons with the mules, or to hold them in dangerous places. By degrees unwillingness seized the weakest; some got the rheumatism, and one, through whose mouth blood came from exertion, died in three days, cursing the hour in which it came to his head to leave New York. We were then in the worst part of the road, near the little river called by the Indians Kiowa. There were no cliffs there as high as on the Eastern boundary of Colorado; but the whole country, as far as the eye could reach, was bristling with fragments thrown in disorder one upon another. These fragments, some standing upright, others overturned, presented the appearance of ruined graveyards with fallen headstones. Those were really the “Bad Lands” of Colorado, answering to those which extended northward over Nebraska. With the greatest effort we escaped from them in the course of a week. [Illustration] [Illustration: CHAPTER VII] AT last we found ourselves at the foot of the Rocky Mountains. Fear seized me when I looked from a proximate point at that world of granite mountains, whose sides were wrapped in mist, and whose summits were lost somewhere in eternal snow and clouds. Their size and silent majesty pressed me to the earth; hence I bent before the Lord, imploring Him to permit me to lead, past those measureless walls, my wagons, my people, and my wife. After such a prayer I entered the stone gullies and corridors with more confidence. When they closed behind us we were cut off from the rest of the world. Above was the sky; in it a few eagles were screaming, around us was granite and then granite without end,—a genuine labyrinth of passages, vaults, ravines, openings, precipices, towers, silent edifices, and as it were chambers, gigantic and dreamy. There is such a solemnity there, and the soul is under such pressure, that a man knows not himself why he whispers instead of speaking aloud. It seems to him that the road is closing before him continually, that some voice is saying to him: “Go no farther, for there is no passage!” It seems to him that he is attacking some secret on which God Himself has set a seal. At night, when those upright legions were standing as black as mourning, and the moon cast about their summits a silvery mantle of sadness, when certain wonderful shadows rose around the “laughing waters,” a quiver passed through the most hardened adventurers. We spent whole hours by the fires, looking with a certain superstitious awe at the dark depths of the ravines, lighted by ruddy gleams; we seemed to think that something terrible might show itself any moment.
