Dear Sir: Your favor of July 9th is just received. I am glad that you have called my attention to the question, "Who are entitled to the principal credit for the passage of the act of Congress establishing the Yellowstone National Park?" The history of that measure, as far as known to me, is as follows, to-wit: In the fall of 1870, soon after the return of the Washburn-Langford party, two printers at Deer Lodge City, Montana, went into the Firehole basin and cut a large number of poles, intending to come back the next summer and fence in the tract of land containing the principal geysers, and hold possession for speculative purposes, as the Hutchins family so long held the Yosemite valley. One of these men was named Harry Norton. He subsequently wrote a book on the park. The other one was named Brown. He now lives in Spokane, Wash., and both of them in the summer of 1871 worked in the New Northwest office at Deer Lodge. When I learned from them in the late fall of 1870 or spring of 1871 what they intended to do, I remonstrated with them and stated that from the description given by them and by members of Mr. Langford's party, the whole region should be made into a National Park and no private proprietorship be allowed. I was elected Delegate to Congress from Montana in August, 1871, and after the election, Nathaniel P. Langford, Cornelius Hedges and myself had a consultation in Helena, and agreed that every effort should be made to establish the Park as soon as possible, and before any person had got a serious foot-hold--Mr. McCartney, at the Mammoth Hot Springs, being the only one who at that time had any improvements made. In December, 1871, Mr. Langford came to Washington and remained there for some time, and we two counseled together about the Park project. I drew the bill to establish the Park, and never knew Professor Hayden in connection with that bill, except that I requested Mr. Langford to get from him a description of the boundaries of the proposed Park. There was some delay in getting the description, and my recollection is that Langford brought me the description after consultation with Professor Hayden. I then filled the blank in the bill with the description, and the bill passed both Houses of Congress just as it was drawn and without any change or amendment whatsoever.
