the rock rivers, and yet for all that a lowlander cannot be said to have truly seen the element of water at all; so even in the richest parks and avenues he cannot be said to have truly seen trees.  For the resources of trees are not developed until they have difficulty to contend with; neither their tenderness of brotherly love and harmony, till they are forced to choose their ways of various life where there is contracted room for them, talking to each other with their restrained branches.  The various action of trees rooting themselves in inhospitable rocks, stooping to look into ravines, hiding from the search of glacier winds, reaching forth to the rays of rare sunshine, crowding down together to drink at sweetest streams, climbing hand in hand among the difficult slopes, opening in sudden dances round the mossy knolls, gathering into companies at rest among the fragrant fields, gliding in grave procession over the heavenward ridges—­nothing of this can be conceived among the unvexed and unvaried felicities of the lowland forest:  while to all these direct sources of greater beauty are added, first the power of redundance,—­the mere quantity of foliage visible in the folds and on the promontories of a single Alp being greater than that of an entire lowland landscape (unless a view from some cathedral tower); and to this charm of redundance, that of clearer visibility,—­tree after tree being constantly shown in successive height, one behind another, instead of the mere tops and flanks of masses, as in the plains; and the forms of multitudes of them continually defined against the clear sky, near and above, or against white clouds entangled among their branches, instead of being confused in dimness of distance.

Finally, to this supremacy in foliage we have to add the still less questionable supremacy in clouds.  There is no effect of sky possible in the lowlands which may not in equal perfection be seen among the hills; but there are effects by tens of thousands, for ever invisible and inconceivable to the inhabitant of the plains, manifested among the hills in the course of one day.  The mere power of familiarity with the clouds, of walking with them and above them, alters and renders clear our whole conception of the baseless architecture of the sky; and for the beauty of it, there is more in a single wreath of early cloud, pacing its way up an avenue of pines, or pausing among the points of their fringes, than in all the white heaps that fill the arched sky of the plains from one horizon to the other.  And of the nobler cloud manifestations,—­the breaking of their troublous seas against the crags, their black spray sparkling with lightning; or the going forth of the morning[27] along their pavements of moving marble, level-laid between dome and dome of snow;—­of these things there can be as little imagination or understanding in an inhabitant of the plains as of the scenery of another planet than his own.
