This is an old business, walking slowly over the land with an appreciation of its immediacy to the senses and in anticipation of what lies hidden in it. The eye alights suddenly on something bright in the grass—the chitinous shell of an insect. The nose tugs at a minute blossom for some trace of arctic perfume. The hands turn over an odd bone, extrapolating, until the animal is discovered in the mind and seen to be moving in the land. One finds anomalous stones to puzzle over, and in footprints and broken spiderwebs the traces of irretrievable events.
