The agricultural wealth of the Andes is mainly concentrated in these table lands, in these millions of rolling acres. The table lands are above the region of forests. About the watercourses, on the farms, and in the towns, a few trees may be found--sometimes avenues of them laid out with care and beauty; and the fruit trees of the temperate zone may here be cultivated; but the great forests of the tropical level and the pines of the mountains are absent. The _Paramos_ are sandy plains, in fact, mountain deserts, in the dry season liable to great droughts, and in the wet season to fearful snowstorms. The armies of Independence, during the wars between Spain and South America, suffered terrible hardships and exposures in the _Paramos_. The _Pampas_ are wide and level plains, not so high as the table lands, where graze innumerable herds of wild cattle. They are beyond the ranges of mountains, in the more central parts of South America. There are none west of the Andes. The table lands complete the sublime varieties of the scenery. Their serenity enchants, as the grandeur of the mountains that rise above them exalts the mind. The works of nature are not only adapted to human need with Omniscient skill, as these fertile lands among the sterner mountains prove; but, feelings different, yet harmonious, are excited by the combinations of Infinite Power. The emotion of awe, being one of great concentration, becomes even painful, if the tension of the mind be too long sustained; and so He who tempers the ineffable splendor of His immediate presence even to the gaze of angels, with the rainbow of emerald about his throne, with the sea of crystal, the tree of life, or the gates of precious stones, also soothes the sublimity of mountains with gentle traits of scenery and soft gradations of color which give enjoyment more passive than awe, and rather captivate than overpower the eye and soul. From the table lands can often be seen in the distance snow-covered tops of mountains, projected in bold, white outlines against the deep-blue sky; and there the sky is really blue, not of that pale tinge that often passes for it, but of a deeper blue than even the rich October sky of North America. As if joining the sky, are the shining summits of the mountains. The two ethereal colors, blue and white, thus meet in dazzling harmony. Sometimes so many of these white, towering heights can be seen, and in so different quarters, that one may almost fancy the sky itself to be a vast dome of sapphire supported by gigantic pillars of marble.
