“Nothing truly wild is unclean.”

If people in general could be got into the woods, even for once, to hear the trees speak for themselves, all difficulties in the way of forest preservation would vanish.

Take me into the mountains.

God has cared for these trees, saved them from drought, disease, avalanches, and a thousand tempests and floods. But he cannot save them from fool.

Handle a book as a bee does a flower, extract its sweetness but do not damage it.

The sun shines not on us but in us.

We were glad, however, to get within reach of information.

The making of gardens and parks goes on with civilization all over the world, and they increase both in size and number as their value is recognized.

Beauty beyond thought everywhere, beneath, above, made and being made forever.

How glorious a greeting the sun gives the mountains!

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