Here is a new approach to conservation in a symbolic story of a mountain. If one must locate Watchdog Mountain, one guess is as good as another. Let's say it might be Bear Mountain, hovering over the Hudson River. From the Indians who first lived there, with wildlife accepted as natural, on through the lumbering of the early settlers, making their clearings, the trapping that stripped the woods and creeks, the big interests that robbed the land of its protection, the floods that came to cleared areas, the commercializing of its natural beauties -- each phase stripped the mountain of its treasure. Then the process began to reverse, as the people recognized their folly and the state stepped in to preserve and conserve and restore. Soft wash drawings by Peter Burchard add an interpretative touch. Not a book children will seek of themselves, but in the new emphasis on conservation, this serves a purpose.
