Thoughtfulness and deliberation are essentials of mountain-climbing. Climb slowly. Look before stepping. Ease down off boulders; a jump may jar or sprain. Enjoy the scenery and do most of your talking while at rest. Think of the fellow lower down. A careful diet and training beforehand will make the climb easier and far more enjoyable. Tyndall has said that a few days of mountain-climbing will burn all the effete matter out of the system. In climbing, the stagnant blood is circulated and refined, the lungs are exercised, every cell is cleansed, and all parts are disinfected by the pure air. Climbing a high peak occasionally will not only postpone death but will give continuous intensity to the joy of living. Every one might well climb at least one high peak, and for those leaving high school or college, the post-graduate work of climbing a rugged peak might be a more informative experience or a more helpful test for living than any examination or the writing of a thesis. Scenery, like music, is thought-compelling and gives one a rare combination of practical and poetical inspiration. Along with mountain-climbing, scenery shakes us free from ourselves and the world. From new grand heights one often has the strange feeling that he has looked upon these wondrous scenes before; and on the crest one realizes the full meaning of John Muir's exhortation to "climb the mountains and get their good tidings!" Wild Mountain Sheep Wild Mountain Sheep One day in Glacier Gorge, Colorado, I was astonished to see a number of sheep start to descend the precipitous eastern face of Thatch-Top Mountain. This glaciated wall, only a few degrees off the perpendicular, rises comparatively smooth for several hundred feet. Down they came, slowly, with absolute composure, over places I dared not even try to descend. The nearness of the sheep and the use of field-glasses gave me excellent views of the many ways in which they actually seemed to court danger. It is intensely thrilling to watch a leaping exhibition of one of these heavy, agile, alert, and athletic animals. Down precipitous places he plunges head foremost, turning and checking himself as he descends by striking his feet against walls and projections--perhaps a dozen times--before alighting on a ledge for a full stop. From this he walks overboard and repeats the wild performance! Wild mountain sheep are perhaps the most accomplished and dare-devil acrobats in the animal world. They are indifferent to the depths beneath as they go merrily along cañon-walls. The chamois and the wild mountain goat may equal them in climbing among the crags and peaks, but in descending dizzy precipices and sheer walls the bighorn sheep are unrivaled. When sheep hurriedly descend a precipice, the laws of falling bodies are given a most spectacular display, and the possibilities of friction and adhesion are tested to the utmost.
