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.

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.

No synonym for God is so perfect as Beauty. Whether as seen carving the lines of the mountains with glaciers, or gathering matter into stars, or planning the movements of water, or gardening - still all is Beauty!

...every sight and sound inspiring, leading one far out of himself, yet feeding and building up his individuality.

One day's exposure to mountains is better than cartloads of books. See how willingly Nature poses herself upon photographers' plates. No earthly chemicals are so sensitive as those of the human soul.

Any fool can destroy trees, they cannot run away.

I care to live only to entice people to look at Nature’s loveliness.
