We still have fragments of the open, useless, untenanted world, and there is an increasing compulsion upon us to preserve these, to set them apart and go and visit them so that we can at least touch the edges of something that is no longer quite within reach. Yet this very drive to preserve and visit the wild spaces may be self-defeating; the mere act of preservation and use robs the wilderness of its virginity; there are perhaps just too many of us nowadays, and it is a serious question whether we can ever again know the grandeur, the loneliness, and the wild, challenging beauty which our continent and our world offered to the adventurous in its youth.

This question bothers Joseph Wood Krutch, and he broods about it thoughtfully in his fine new book, Grand Canyon .

The Grand Canyon is one of our most spectacular natural beauties. This enormous gash in the earth exists in one of the desolate corners of the United States, but the nation is beginning to push in on it; more and more people who want nothing so much as to get away from the rush and noise of modern life are going there to find something that cannot be found at home, and the disturbing question, as Mr. Krutch points out, is whether something like this can possibly coexist with energetic exploitation.

It is only the United States which can still, among the highly developed nations, offer its people the chance to visit large areas where nature is still unspoiled. We did start early; we set aside these great empty areas as public lands, and did our best to save them for people who would have to live in a nation where precious little remains unspoiled. But we still have “the power to ravage,” and it is by no means sure that we will always restrain ourselves in the use of that power. These primitive areas have timber, or grazing resources, or water power, or simply unoccupied acres that may be built up in neat real-estate subdivisions. We say, “Human needs come first”—but precisely what human needs are we thinking about? Mr. Krutch feels that we need to be clear about what needs may be most important. Material needs may not be the really valuable ones. As he remarks:

If we recognize that there is more than one kind of utility and that the parks are, at the present moment, being put to the best use to be found for them, then they may last a long time—until, perhaps, overpopulation has reached the point where the struggle for mere animal survival is so brutal that no school or theater, or concert hall or church, can be permitted to “waste” the land on which it
