Nature is just a dictionary, you hunt in it for words.. ..you find in it the elements which make a phrase or a story; but nobody would regard a dictionary as a composition in the poetic sense of the term. Besides, nature is far from being always interesting from the point of view of the effect of the whole.. .If each detail is perfect in some way, the union of these details seldom gives an effect equivalent to that which arises, in the work of a great artist, from the total composition.
