" The Cambridge flowers had a moral meaning...but they had a poetical meaning that was even more apparent. So did the sounds one heard on summer evenings, the bells of the cows ambling home at twilight, the lullaby of the crickets in early autumn, the hymns of the frogs, in spring, in some neighbouring swamp, not to speak of the creaking of the winter wood-sleds, dragging their loads of walnut over the complaining snow. Every sound and odour had its value. "
