Long ago, men proved their superiority to other men by butchering each other in hordes and droves and shambles; Alva must have had a good 100,000 corpses to his credit in the Netherlands. To-day, men make good by conquering the elements. For four hours, this little Colorado road has been cork-screwing up the face of a mountain pretty nearly sheer as a wall; and for every twist and turn and tunnel, some engineer fellow on the job has performed mathematical acrobatics; and some capitalist behind the engineer--the man behind the modern gun of conquest--has paid the cost. In this case, it was David Moffat paid for our dance in the clouds--a mining man, who poked his brave little road over the mountains across the desert towards the Pacific. [Illustration: From a lookout point in the Coconino Forest of Arizona] You come through those upper tunnels still higher. Below, no longer lie the plains, but seas of clouds; and it is to the everlasting credit of the sense and taste of Denver people, that they have dotted the outer margin of this rock wall with slab and log and shingle cottages, built literally on the very backbone of the continent overlooking such a stretch of cloud and mountain and plain as I do not know of elsewhere in the whole world. In Sundance Canyon, South Dakota, summer people have built in the bottom of the gorge. Here, they are dwellers in the sky. Rugged pines cling to the cliff edge blasted and bare and wind torn; but dauntlessly rooted in the everlasting rocks. Little mining hamlets composed of matchbox houses cling to the face of the precipice like cardboards stuck on a nail. Then, you have passed through the clouds, and are above timber line; and a lake lies below you like a pool of pure turquoise; and you twist round the flank of the great mountain, and there is a pair of green lakes below you--emerald jewels pendant from the neck of the old mountain god; and with a bump and a rattle of the wheels, clear over the top of the Continental Divide you go--believe me, a greater conquest than any Napoleon's march to Moscow, or Alva's shambles of headless victims in the Netherlands. You take lunch in a snow shed on the very crest of the Continental Divide. I wish you could taste the air. It isn't air. It's champagne. It isn't champagne, it's the very elixir of life. There can never be any shadows here; for there is nothing to cast the shadow. Nightfall must wrap the world here in a mantle of rest, in a vespers of worship and quiet, in a crystal of dying chrysoprase above the green enameled lake and the forests below, looking like moss, and the pearl clouds, a sea of fire in the sunset, and the plain--there are no more plains--this is the top of the world!
