In order that the beauty of the Big Oak Flat Road may be unimpaired, arrangements have been made between the Sugar Pine Lumber Co., the Forest Service, the State, and the Park Service to preserve the roadsides through selective cutting of the larger trees and careful removal of any trees that are taken out. Particularly interesting and valuable stands of timber which should be preserved untouched will be made the subject of exchanges between the Forest Service and the Sugar Pine Lumber Co. This land acquisition program was finally assured of success in July, 1937, when legislation authorized the Secretary of the Interior to acquire the Carl Inn Tract, comprising some 7,200 acres of magnificent sugar pine forest bordering the western boundary of the park. After a year and a half of negotiations with the Yosemite Sugar Pine Lumber Company, owner of most of the tract, agreement was reached on a price of $1,495,500 to be paid by the United States. The purchase was consummated early in 1939. Senator William Gibbs McAdoo and Representative John S. McGroarty, both of California, were the ardent supporters who introduced the bills, S. 1791 and H.R. 5394, in their respective houses. Policies regarding the toll roads by which tourists could enter the park constituted another perplexing problem with which the young National Park Service was confronted. The routes had been privately constructed and were privately owned and controlled by turnpike companies. Government funds were not available with which to purchase them outright. One company was persuaded to turn the Wawona Road over the public in exchange for a grant for the exclusive rights to the route during a certain number of years. The government assumed responsibility for the maintenance of the road during this period. The owners of the Coulterville Road could not be persuaded to agree to such a plan. As a result, that part of it which is within the park has not been maintained and, because of erosion, has fallen into disuse.
