coyote: meanwhile, an old adversary of muir's stepped forward on the city's behalf-- gifford pinchot. as the nation's top forester and president roosevelt's trusted adviser, pinchot had become one of the most powerful men in washington. at his urging, roosevelt had reserved millions of acres of western land as national forests in the face of congressional opposition. pinchot steadfastly believed that conservation meant wise use of nature not preserving it for its own sake and he had never been a wholehearted supporter of national parks, let alone john muir's unbending vision of protecting and expanding them. when a new interior secretary joined the administration, pinchot began lobbying him in support of the dam. in response, muir once again took his case to the man with whom he had shared 3 magical nights in the park back in 1903-- the outdoorsman he considered a friend and kindred spirit. man as john muir: april 21 1908. dear mr. president a few promoters of the present scheme all show forth a proud set of confidence that comes from a good, sound, substantial irrefragable ignorance.
