The mountains are calling and I must go.

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.

Thousands of tired, nerve-shaken, over-civilized people are beginning to find out that going to the mountains is going home; that wildness is a necessity.

When we try to pick out anything by itself, we find it hitched to everything else in the universe.

I wonder if leaves feel lonely when they see their neighbors falling?

Raindrops blossom brilliantly in the rainbow, and change to flowers in the sod, but snow comes in full flower direct from the dark, frozen sky.

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.
