We stand guard over works of art, but species representing the work of aeons are stolen from under our noses. - Aldo Leopold

It is a century now since Darwin gave us the first glimpse of the origin of species. We know now what was unknown to all the preceding caravan of generations: that men are only fellow-voyagers with other creatures in the odyssey of evolution. This new knowledge should have given us, by this time, a sense of kinship with fellow-creatures; a wish to live and let live; a sense of wonder over the magnitude and duration of the biotic enterprise.

The ordinary citizen today assumes that science knows what makes the community clock tick; the scientist is equally sure that he does not.

What more delightful avocation than to take a piece of land and, by cautious experimentation, to prove how it works? What more substantial service to conservation than to practice it on one's own land?
