in Thoreau’s Journal:
….the melon-rind arrangement of the clouds, really parallel columns of fine mackerel sky reaching quite across the heavens from west to east, with clear intervals of blue sky; and a fine-grained vapor like spun glass extending in the same direction beneath the former….But how long can a man be in a mood to watch the heavens?
….What a spectacle the subtle vapors that have their habitation in the sky present these winter days! You have not only unvarying forms of a given type of cloud, but various types at different heights or hours. It is a scene, for variety, for beauty and grandeur, out of all proportion to the attention it gets. Who watched the forms of the clouds over this part of the earth a thousand years ago? who watches them to-day?
