Thoreau writes in his journal:
This is a peculiar season, peculiar for its stillness. The crickets have ceased their song. The few birds are well-nigh silent. The tinted and gay leaves are now sere and dead, and the woods wear a sombre aspect. A carpet of snow under the pines and shrub oaks will make it look more cheerful. Very few plants have now their spring. But thoughts still spring in man’s brain.
