Again, steep, rocky roads lead over rugged cliffs. Your horses climb panting, and descend, picking their steps, upon the other side. Stop awhile on this green space, a valley between two high ridges. Countless flowers spread fragrance and beauty around. They are not those alone of the strictly tropical level, but, owing to the height above the sea, the floral wealth of the temperate zone is embosomed in the torrid region itself, and adds the charm of an almost magical diversity to the intrinsic splendors of the scene. See small objects flitting about from flower to flower. They are the smallest and most delicate of hummingbirds, nowhere found but in America. Watch their colors, changing with every changing motion, purple, crimson, golden, green. It is as if the very flowers had taken life, and were revelling with conscious glee in the soft, bright air. The hues of these birds are dazzlingly bright. The little creatures glance about like prismatic rays embodied in the smallest visible forms. After gazing upon these hummingbirds with joy as great as theirs, as they revel like fairies in the profusion of this flowery valley, look upward on the high, grand ridges that close it in. What suddenly starts from the very top of yon cliff, and floats in the air, high, high, above you? It is the great condor, expanding his broad wings, wheeling in flight from ridge to ridge, curving with majestic motion, now poising himself upon his wings, now apparently descending, now suddenly but gracefully turning upward, until his lessening shape has gone beyond the farthest reach of sight. The hummingbird and the condor; hillsides covered with sheep; rocky ridges inaccessible to man or beast; brooks that quiver gently on; impetuous torrents; the beauty of Eden and craggy desolation like that of chaos--these all can you see among the Andes. Let not the fascination of this valley, the songs of birds, the flowers, the hummingbirds glistening among them like gems, the soft outlines of the scenery detain you long. Harder and sterner scenes await you. The Andes are a picture of life. Every cliff records a lesson; and the unnumbered flowers interweave with their varied dyes and rich perfumes gentle suggestions, sweet similitudes for the understanding and the heart. If, as in this charming valley, the senses may be dissolved in joy, and the spirit would linger willingly in rapt delight, soon some hard experience, kindly sent, requires one to brace all manly energy for the rough encounter, the blast of peril, and duty's steep and craggy road. You ascend in narrowing ways, casting long, lingering looks upon the valley, whenever it opens to view between the cliffs.
