The clearest way into the Universe is through a forest wilderness.

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.

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

The axe and saw are insanely busy, chips are flying thick as snowflakes, and every summer thousands of acres of priceless forests, with their underbrush, soil, springs, climate, scenery, and religion, are vanishing away in clouds of smoke, while, except in the national parks, not one forest guard is employed.

Most people who travel look only at what they are directed to look at. Great is the power of the guidebook maker, however ignorant.

When I first caught sight of (Mount Shasta) over the braided folds of the Sacramento Valley I was fifty miles away and afoot, alone and weary. Yet all my blood turned to wine, and I have not been weary since.
