A rainy day is the perfect time for a walk in the woods. I always thought so myself; the Maine woods never seem so fresh and alive as in wet weather. Then all the needles on the evergreens wear a sheath of silver; ferns seem to have grown to almost tropical lushness and every leaf has its edging of crystal drops. Strangely colored fungi — mustard-yellow and apricot and scarlet — are pushing out of the leaf mold and all the lichens and the mosses have come alive with green and silver freshness.
