To be admitted to Nature's hearth costs nothing. None is excluded, but excludes himself. You have only to push aside the curtain.

Nature puts no question and answers none which we mortals ask. She has long ago taken her resolution.

I frequently tramped eight or ten miles through the deepest snow to keep an appointment with a beech-tree, or a yellow birch, or an old acquaintance among the pines.

You must not know too much or be too precise or scientific about birds and trees and flowers and watercraft; a certain free-margin, and even vagueness - ignorance, credulity - helps your enjoyment of these things.

Live in each season as it passes; breathe the air, drink the drink, taste the fruit, and resign yourself to the influence of the earth.

None are so old as those who have outlived enthusiasm.
