Wilderness is the raw material out of which man has hammered the artifact called civilization.

The land-relation is still strictly economic, entailing privileges but not obligations

The government tells us we need flood control and comes to straighten the creek in our pasture. The engineer on the job tells us the creek is now able to carry off more flood water, but in the process we have lost our old willows where the owl hooted on a winter night and under which the cows switched flies in the noon shade. We lost the little marshy spot where our fringed gentians bloomed.

Acts of creation are ordinarily reserved for gods and poets, but humbler folk may circumvent this restriction if they know how. To plant a pine, for example, one need be neither god nor poet; one need only own a shovel.

This song of the waters is audible to every ear, but there is other music in these hills, by no means audible to all. On a still night, when the campfire is low and the Pleiades have climbed over rimrocks, sit quietly and listen, and think hard of everything you have seen and tried to understand. Then you may hear it - a vast pulsing harmony - its score inscribed on a thousand hills, its notes the lives and deaths of plants and animals, its rhythms spanning the seconds and the centuries.
