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 assimilated, 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.
Through the long-lingering half-light of the most superb of evenings we return'd to Denver, where I staid several days leisurely exploring, receiving impressions, with which I may as well taper off this memorandum, itemizing what I saw there. The best was the men, three-fourths of them large, able, calm, alert, American. And cash! why they create it here. Out in the smelting works, (the biggest and most improv'd ones, for the precious metals, in the world,) I saw long rows of vats, pans, cover'd by bubbling-boiling water, and fill'd with pure silver, four or five inches thick, many thousand dollars' worth in a pan. The foreman who was showing me shovel'd it carelessly up with a little wooden shovel, as one might toss beans. Then large silver bricks, worth $2000 a brick, dozens of piles, twenty in a pile. In one place in the mountains, at a mining camp, I had a few days before seen rough bullion on the ground in the open air, like the confectioner's pyramids at some swell dinner in New York. (Such a sweet morsel to roll over with a poor author's pen and ink--and appropriate to slip in here--that the silver product of Colorado and Utah, with the gold product of California, New Mexico, Nevada and Dakota, foots up an addition to the world's coin of considerably over a hundred millions every year.)
