VI
There are four excursions that you should make this spring: one to a small pond in the woods; one to a deep, wild swamp; one to a wide salt marsh or fresh-water meadow; and one to the seashore—to a wild rocky or sandy shore uninhabited by man.
There are particular birds and animals as well as plants and flowers that dwell only in these haunts; besides, you will get a sight of four distinct kinds of landscape, four deep impressions of the face of nature that are altogether as good to have as the sight of four flowers or birds.
