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.

Everybody needs beauty as well as bread, places to play in and pray in, where nature may heal and give strength to body and soul.

In every walk with nature one receives far more than he seeks.

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.

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