Take a course in good water and air; and in the eternal youth of Nature you may renew your own. Go quietly, alone; no harm will befall you.

...full of God's thoughts, a place of peace and safety amid the most exalted grandeur and enthusiastic action, a new song, a place of beginnings abounding in first lessons of life, mountain building, eternal, invincible, unbreakable order; with sermons in stone, storms, trees, flowers, and animals brimful with humanity.

Few places in this world are more dangerous than home. Fear not, therefore, to try the mountain passes. They will kill care, save you from deadly apathy, set you free, and call forth every faculty into vigorous, enthusiastic action.

The gross heathenism of civilization has generally destroyed nature, and poetry, and all that is spiritual.

There are no accidents in Nature. Every motion of the constantly shifting bodies in the world is timed to the occasion for some definite, fore-ordered end. The flowers blossom in obedience to the same law that marks the course of constellations, and the song of a bird is the echo of a universal symphony. Nature is one, and to me the greatest delight of observation and study is to discover new unities in this all-embracing and eternal harmony.

Keep close to Nature's heart... and break clear away, once in awhile, and climb a mountain or spend a week in the woods. Wash your spirit clean.

A little pure wildness is the one great present want, both of men and sheep.
