PREFACE Yellowstone National Park lives as a cherished memory in the minds of millions of people. Greater still is the number who anticipate a visit to this Wonderland. To nearly all, the Park stands as a symbol of the enrichment of the American way of life. And well it might, because it is a geological paradise, a pristine botanical garden, and an Elysium for wild game. But most important of all, it is a place of recreation for countless thousands who come to find a temporary escape from the pressure of a highly artificial life. Thoughtful people assent to the opinion of Wordsworth: The world is too much with us; late and soon, Getting and spending, we lay waste our powers; Little we see in Nature that is ours; We have given our hearts away, a sordid boon! This Sea that bares her bosom to the moon; The winds that will be howling at all hours, And are up-gathered now like sleeping flowers; For this, for everything, we are out of tune; It moves us not. —Great God! I’d rather be A Pagan suckled in a creed outworn; So might I, standing on this pleasant lea, Have glimpses that would make me less forlorn; Have sight of Proteus rising from the sea; Or hear old Triton blow his wreathed horn.
