Then Muir began to slide up that mountain. I had been with mountain climbers before, but never one like him. A deer-lope over the smoother slopes, a sure instinct for the easiest way into a rocky fortress, an instant and unerring attack, a serpent-glide up the steep; eye, hand and foot all connected dynamically; with no appearance of weight to his body—as though he had Stockton's negative gravity machine strapped on his back.

Fifteen years of enthusiastic study among the Sierras had given him the same pre-eminence over the ordinary climber as the Big Horn of the Rockies shows over the Cotswold. It was only by exerting myself to the limit of my strength that I was able to keep near him. His example was at the same time my inspiration and despair. I longed for him to stop and rest, but would not have suggested it for the world. I would at least be game, and furnish no hint as to how tired I was, no matter how chokingly my heart thumped. Muir's spirit was in me, and my "chief end," just then, was to win that peak with him. The impending calamity of being beaten by the sun was not to be contemplated without horror. The loss of a fortune would be as nothing to that!

THE MOUNTAIN
He pointed to a little group of jagged peaks rising right up from where we stood—a pulpit in the center of a vast rotunda of magnificent mountains

We were now beyond the flower garden of the gods, in a land of rocks and cliffs, with patches of short grass, caribou moss and lichens between. Along a narrowing arm of the mountain, a deep canyon flumed a rushing torrent of icy water from a small glacier on our right. Then came moraine matter, rounded pebbles and boulders, and beyond them the glacier. Once a giant, it is nothing but a baby now, but the ice is still blue and clear, and the crevasses many and deep. And that day it had to be crossed, which was a ticklish task. A misstep or slip might land us at once fairly into the heart of the glacier, there to be preserved in cold storage for the wonderment of future generations. But glaciers were Muir's special pets, his intimate companions, with whom he held sweet communion. Their voices were plain language to his ears, their work, as God's landscape gardeners, of the wisest and best that Nature could offer.

No Swiss guide was ever wiser in the habits of glaciers than Muir, or proved to be a better pilot across their deathly crevasses. Half a mile of careful walking and jumping and we were on the ground again, at the base of the great cliff of metamorphic slate that crowned the summit. Muir's aneroid barometer showed a height of about seven thousand feet, and the wall of rock towered threateningly above us, leaning out in places, a thousand feet or so above the glacier. But the earth-fires that had melted and heaved it, the ice mass that chiseled and shaped it, the wind and rain that corroded and crumbled it, had left plenty of bricks out of that battlement, had covered its face with knobs and horns, had ploughed ledges and cleaved fissures and fastened crags and pinnacles upon it, so that, while its surface was full of man-traps and blind ways, the human spider might still find some hold for his claws.

The shadows were dark upon us, but the lofty, icy peaks of the main range still lay bathed in the golden rays of the setting sun. There was no time to be lost. A quick glance to the right and left, and Muir, who had steered his course wisely across the glacier, attacked the cliff, simply saying, "We must climb cautiously here."
