in Thoreau’s Journal:
Take the most rigid tree, the whole effect is peculiarly soft and spirit-like, for there is no marked edge or outline. How could you draw the outline of these snowy fingers seen against the fog, without exaggeration? There is no more a boundary-line or circumference that can be drawn, than a diameter. Hardly could the New England farmer drive to market under these trees without feeling that his sense of beauty was addressed. He would be aware that the phenomenon called beauty was become visible, if one were at leisure or had had the right culture to appreciate it. A miller with whom I rode actually remarked on the beauty of the trees; and a farmer told me in all sincerity that, having occasion to go into Walden Woods in his sleigh, he thought he never saw anything so beautiful in all his life, and if there had been men there who knew how to write about it, it would have been a great occasion for them.
