[148]In Dr. Hayden’s “Brief Statement of the History of the National Park,” which he forwarded to the Secretary of the Interior, Carl Schurz, on February 21, 1878, the following appeared: “I beg permission to state here, that so far as I know, I originated the idea of the park, prepared the maps, designating the boundaries, and in connection with the Hon. W. H. Claggett [sic], then Delegate from Montana Territory, wrote the law as it now stands.... It is now acknowledged all over the civilized world that the existence of the National Park, by law, is due solely to my exertions during the sessions of 1871 and 1872.” House Executive Documents, Forty-fifth Congress, Second Session, 1877-78, XVII, No. 75, 3.
