At timberline I stopped in silent wonder. Broken trees were scattered about upon the ground like soldiers after a battle. I didn't quite comprehend its significance, but Parson Lamb had described it to me. I had seen other timberlines in my rambles, but none so impressive as this. Here was the forest frontier. How dauntless, how gallant, these pioneers were! How they strove to hold the advantage gained during the brief summer respite! Here a canny stripling grew behind a sheltering bowlder, but whenever it tried to peep above its breastworks, the wind, with its shell-shot of sand and gravel and ice bullets, cut off its protruding limbs as neatly as a gardner might have done. Consequently its top was as flat as a table. In the open, other trees trailed along the ground like creeping vines, their tops pointing away from the wind. It seemed as if they banded together for mutual protection, for they formed a dense hedge or "bush." Here was the deadline established by altitude. The forests were commanded to halt; this line of last defense was not unlike the sweeping shoreline of the sea. Here and there were lone scout trees in advance of the ranks. They were twisted and dwarfed, misshapen, grotesque. There were wide, naked stretches bare of snow. Great drifts lay in the woods; the deep, narrow cañons were piled full of it. Many of these drifts would last far into the following summer; a few would be perpetual. At the approach of summer, such drifts turn to ice through frequent thawing and freezing, since the surface snow, melting under the glare of the summer sun, seeps down through the mass beneath in daytime, and freezes again at night. From such drifts flow icy streams for the leaping trout. Countless sparkling springs gurgled forth at the foot of the slopes. Here I had my first lessons in conservation and learned that it is indeed an ill wind that does no good. Here nature hoards her savings in snowbanks. To these savings she adds constantly throughout the winter. Long I sat upon a promontory and marveled. Dimly, only, did I grasp the significance of what lay before me! The ranks of primeval forest waiting to aid civilization; snow, that white magic eventually destined to water crops on the distant plains; and, above all, woods, the final refuge of the big game; the sanctuary of the birds. Everywhere were scattered unnamed lakes. These edged out and around the rock peninsulas, folded back into dark coves and swung out of sight behind the timbered bends. Some were almost pinched in half by the crowding cliffs till they formed giant hour-glasses; again they bulged and overflowed like streams at high water. I began to name them according to their shape. "Hourglass," of course; the one that bulged out at one end was surely a plump "Pear"--yes, and "Dog-with-three-legs"! My imagination was recovering.
