Thoreau writes in his journal:
One must needs climb a hill to know what a world he inhabits. In the midst of this Indian summer I am perched on the topmost rock of Nawshawtuct, a velvet wind blowing from the southwest. I seem to feel the atoms they strike my cheek. Hills, mountains, steeples stand out in bold relief in the horizon, while I am resting on the rounded boss of an enormous shield, the river like a vein of silver encircling its edge, and thence the shield gradually rises to its rim, the horizon. Not a cloud is to be seen, but villages, villas, forests, mountains, one above another, till they are swallowed up in the heavens. The atmosphere is such that, as I look abroad upon the length and breadth of the land, it recedes from my eye, and I seem to be looking for the threads of velvet. Thus I admire the grandeur of my emerald carriage, with its border of blue, in which I am rolling through space.
