"'At intervals, we reached places where a number of springs gushed from the rocks, and about 1,800 feet above the lakes came to the snow line. From this point our progress was uninterrupted climbing. Hitherto, I had worn a pair of thick moccasins, with soles of _parfleche_; but here I put on a light thin pair, which I had brought for the purpose, as now the use of our toes became necessary to a further advance. I availed myself of a sort of comb of the mountain, which stood against the wall like a buttress, and which the wind and the solar radiation, joined to the steepness of the smooth rock, had kept almost entirely free from snow. Up this I made my way rapidly. Our cautious method of advancing in the outset had spared my strength; and, with the exception of a slight disposition to headache, I felt no remains of yesterday's illness. In a few minutes we reached a point where the buttress was overhanging, and there was no other way of surmounting the difficulty than by passing around one side of it, which was the face of a vertical precipice of several hundred feet.' "_Parfleche_ is the name given to buffalo hide. The Indian women prepare it by scraping and drying. It is exceedingly tough and hard, and receives its name from the circumstance that it cannot be pierced by arrows or spears. The entire dress of Fremont and his party, on their ascent to the 'top of America,' consisted of a blue flannel shirt, free and open at the neck, the collar turning down over a black silk handkerchief tied loosely, blue cloth pantaloons, a slouched broad-brimmed hat, and moccasins as above described. It was well adapted to climbing--quite light, and at the same time warm, and every way comfortable.
