in Thoreau’s Journal:
A fine, freshening air, a little hazy, that bathes and washes everything, saving the day from extreme heat. Walked to the hills south of Wayland by the road by Deacon Farrar’s. First vista just beyond Merron’s (?), looking west down a valley, with a verdant-columned elm at the extremity of the vale and the blue hills and horizon beyond. These are the resting-places in a walk. We love to see any part of the earth tinged with blue, cerulean, the color of the sky, the celestial color.
I wonder that houses are not oftener located mainly that they may command particular rare prospects, every convenience yielding to this. The farmer would never suspect what it was you were buying, and such sites would be the cheapest of any. A site where you might avail yourself of the art of Nature for three thousand years, which could never be materially changed or taken from you, a noble inheritance for your children. The true sites for human dwellings are unimproved. They command no price in the market. Men will pay something to look into a travelling showman’s box, but not to look upon the fairest prospects on the earth. A vista where you have the near green horizon contrasted with the distant blue one, terrestrial with celestial earth. The prospect of a vast horizon must be accessible in our neighborhood. Where men of enlarged views may be educated. An unchangeable kind of wealth, a real estate.
