" In the night the eyes are partly closed, or retire into the head. Other senses take the lead. The walker is guided as well by the sense of smell. Every plant and field and forest emits its odor now, —swamp-pink in the meadow, and tansy in the road; and there is the peculiar dry scent of corn which has begun to show its tassels. The senses both of hearing and smelling are more alert. We hear the tinkling of rills which we never detected before. "

― Henry David Thoreau , La noche y la luz de la luna
