Suddenly the walls shot upward almost perpendicularly for hundreds of feet, shutting out the sunlight, leaving nothing visible but a narrow strip of sky; and still the great rocks came closer and closer, until little more than the width of the car was left, and it seemed that in a moment that must be crushed. The ponderous wheels were slowly revolving over a trestle bridge of steel, mortised into the rocks, while the deafening echoes reverberated between the narrowing walls, and rippled the surface of the river flowing deep and black below. Then suddenly another swift, sharp turn, and they were out in the dazzling sunshine, amidst a scene of untold beauty and grandeur. Here, at the entrance of the canyon, the train stopped, giving the passengers an opportunity to alight and enjoy the scenery. On all sides rose masses of rock, some fashioned in wondrous beauty, others in forms weird and fantastic; some gray and rugged, some tinted with intermingling shades of color, and others sparkling in the sunlight as though studded with gems innumerable. Here and there were piles of rock, crimson and green and golden, resembling the moss-grown, ivy-covered castles of the olden time. Farther on were mountains covered with heavy forests of pine, through which the winds sighed and whispered mysteriously, while at their feet the little streams lingered lovingly long enough to catch the whispered secrets, and bear them away, laughing and singing, on their journey toward the great sea. The train moved slowly on to another canyon, more grand in its awful solitude than the first, surrounded on all sides by walls nearly a thousand feet in height. At one side, a broad sheet of water, shimmering in the sunlight, fell, like a bridal veil, down the precipitous rock, with a deafening roar disappearing into unseen depths below, while at the base of the canyon lay a lake of sapphire, in whose calm, untroubled depths, rocks and cascade and sky were mirrored in perfect beauty. Slowly the train wound its way upward, until it paused again near the summit of the range, on the "divide," the boundary line between the east and the west. There were the serried ranks of the mountains, vast, solemn, grand; and in that awful solitude, under the spell of that eternal silence, a sense of the infinite hushed every tongue, and each one stood with bated breath, as if on holy ground. On every side the billowy ranges surged, like the gigantic waves of a storm-tossed ocean suddenly congealed to stone, while here and there, towered mighty peaks, like huge sentinels, their brows seamed with furrows plowed by the hand of the centuries, their heads white with the snows of countless ages. Here two tiny streams flowed side by side, then separated; the one to start on its long journey toward the old Atlantic, the other toward the Golden Gate, to mingle its waters with those of the sunset sea.
