Recently I was visited by a very good friend who had just returned from a long walk in the woods, and I asked her what she had observed. 'Nothing in particular,' she replied. I might have been incredulous had I not been accustomed to such responses, for long ago I became convinced that the seeing see little. How was it possible, I asked myself, to walk for an hour through the woods and see nothing worthy of note? I who cannot see find hundreds of things to interest me through mere touch. I feel the delicate symmetry of a leaf. I pass my hands lovingly about the smooth skin of a silver birch, or the rough, shaggy bark of a pine. In spring I touch the branches of trees hopefully in search of a bud, the first sign of awakening Nature after her winter's sleep. I feel the delightful, velvety texture of a flower, and discover its remarkable convolutions; and something of the miracle of Nature is revealed to me.
