But it is not so much actual facts, as what men believe these facts to be, that controls human action; and it is unquestionably true that the above quotation correctly expresses the views of the great majority of members of Congress when the Park measure was before that body. It is not too much to say that Dr. Hayden's influence, as the official representative of the government, was a controlling factor in the passage of that measure. Perhaps no act of our national Congress has received such general approbation at home or such profuse commendation from foreigners as that creating the Yellowstone National Park. The lapse of twenty years has only served to confirm and extend its importance; and to give additional force to the sentiment so well expressed by the Earl of Dunraven when he visited the Park in 1874: "All honor then to the United States for having bequeathed as a free gift to man the beauties and curiosities of 'Wonderland.' It was an act worthy of a great nation, and she will have her reward in the praise of the present army of tourists, no less than in the thanks of the generations of them yet to come."[AH] [AH] Page xi, "The Great Divide." See Appendix E. It was a notable act, not only on account of the transcendent importance of the territory it was designed to protect, but because it was a marked innovation in the traditional policy of governments. From time immemorial privileged classes have been protected by law in the withdrawal, for their exclusive enjoyment, of immense tracts for forests, parks and game preserves. But never before was a region of such vast extent as the Yellowstone Park set apart for the use of all the people without distinction of rank or wealth. The example thus set by the United States has been widely followed. We have now the Yosemite and Sequoia National Parks, and numerous parks upon the sites of great battle-fields. The State of New York has a Niagara Park and contemplates setting apart a portion of the Adirondack region. Minnesota has the Itasca State Park, including the sources of the Mississippi. Canada also has a public park at Niagara, and a large reservation in the midst of the finest scenery of the Rocky Mountains. New Zealand has set a part for public use the region of her hot springs and geysers. Finally the question is being mooted of reserving a vast tract of Africa wherein the large game of that continent may be kept from annihilation. CHAPTER XI. WHY SO LONG UNKNOWN?
