Fluid the world flowed under us: the hills
Billow on billow of umbrageous green
Heaved us, aghast, to fresh horizons, seen
One rapturous instant, blind with flash of rills
And silver-rising storms and dewy stills
Of dripping boulders, till the dim ravine
Drowned us again in leafage, whose serene
Coverts grew loud with our tumultuous wills.
Then all of Nature's old amazement seemed
Sudden to ask us: "Is this also Man?
This plunging, volant, land-amphibian
What Plato mused and Paracelsus dreamed?
Reply!" And piercing us with ancient scan,
The shrill, primeval hawk gazed down -- and screamed.
