I returned to Yosemite in the summer of 1921—again in coöperation with Dr. Bryant. The movement seemed to be well on its feet so I withdrew at the end of that summer. We were appointed as temporary rangers with duties informally defined. Each morning a field trip was conducted by one or the other of us alternately, the alternate holding office hours for questions by visitors. (Questions averaged 45 to the hour). In the afternoon a children’s field class was held. In the evening we alternated with talks at Camp Curry and the “Old Village” near Sentinel Bridge. They were busy days but interest was good. Week ends were devoted to overnight trips by one or the other of us. At the urgent request of Mr. Ansel Hall I initiated the same type of work at Crater Lake Park, Oregon, in 1926 and continued it in 1927. My son, Alden Miller, was associated with me and two students, Miss Leigh Marian Larson and Miss Ruth Randall, acted as volunteers in charge of wildflower display. Reports of this work should be in the Crater Lake files. During the summer we were visited by Mr. Mather, by Dr. John C. Merriam, and by Mr. John D. Rockefeller and family. The interest of these men was immediate and finally bore material fruit in improvement of Crater Lake Park and the whole Nature Guide movement in America. Just as had been the case at Yosemite, we were appointed as rangers. My duties at Crater Lake included nature guiding, directing traffic, comforting crying babies, rounding up stray dogs, and a wild drive down the mountain to Medford Hospital with a writhing appendicitis patient and his distracted wife in the rear seat. I have not been officially connected with the work since but have sent many graduate students to the Yosemite Field School with what I hope was the right point of view. My own retirement at 70 years leaves me out of the picture except in an advisory capacity. Just last week in conference with my associates here, I urged Park Naturalist activity as one of the public services for which our department should train young men. So you see that my interests are still with the movement. It is a field of infinite horizon. Sincerely yours, Loye Miller March 18, 1946. Dr. H. C. Bryant, the coworker referred to by Dr. Miller, became Assistant Director of the National Park Service in charge of interpretive work for all national parks. To Dr. Miller’s statement may be added Bryant’s words about interpretive work:
