Talk, I say again, of going to Europe, of visiting the ruins of feudal castles, or Coliseum remains, or kings' palaces—when you can come here. The alternations one gets, too; after the Illinois and Kansas prairies of a thousand miles—smooth and easy areas of the corn and wheat of ten million democratic farms in the future——here start up in every conceivable presentation of shape, these non-utilitarian piles, coping the skies, emanating a beauty, terror, power, more than Dante or Angelo ever knew. Yes, I think the chyle of not only poetry and painting, but oratory, and even the metaphysics and music fit for the New World, before being finally a**imilated, need first and feeding visits here. Mountain streams.—The spiritual contrast and etheriality of the whole region consist largely to me in its never-absent peculiar streams—the snows of inaccessible upper areas melting and running down through the gorges continually. Nothing like the water of pastoral plains, or creeks with wooded banks and turf, or anything of the kind elsewhere. The shapes that element takes in the shows of the globe cannot be fully understood by an artist until he has studied these unique rivulets. Aerial effects.—But perhaps as I gaze around me the rarest sight of all is in atmospheric hues. The prairies—as I cross'd them in my journey hither—and these mountains and parks, seem to me to afford new lights and shades. Everywhere the aerial gradations and sky-effects inimitable; nowhere else such perspectives, such transparent lilacs and grays. I can conceive of some superior landscape painter, some fine colorist, after sketching awhile out here, discarding all his previous work, delightful to stock exhibition amateurs, as muddy, raw and artificial. Near one's eye ranges an infinite variety; high up, the bare whitey-brown, above timber line; in certain spots afar patches of snow any time of year; (no trees, no flowers, no birds, at those chilling altitudes.) As I write I see the Snowy Range through the blue mist, beautiful and far off, I plainly see the patches of snow.
