9§ Roosevelt Wild Life Bulletin 



Horace M. Albright, to put a field party at work on important wild 

 life problems in the Park. 



The food of the stream fishes is being investigated by Dr. Richard 

 A. Muttkowski of the University of Idaho, and Dr. Gilbert M. Smith 

 of the University of Wisconsin. These are fundamental studies 

 underlying the maintenance of the fish in the Park, a problem never 

 having been studied before in this region. With the great increase 

 of Park visitors and the excessive demand for trout fishing, the 

 problem of maintaining the supply has become a very serious one. 

 Mr. Edward R. Warren, the well-known authority on Colorado 

 mammals, is making a detailed study of the beaver ponds and dams, 

 which have been carefully surveyed and mapped. He has been 

 assisted by E. J. Spackman, Jr. Mr. Edmund Heller, the eminent 

 field naturalist who accompanied Roosevelt on his African expedi- 

 tion, is conducting an investigation of the large mammals of the 

 Park, giving special attention to photographic records. He has been 

 very materially assisted by a grant from two friends of the Station. 



Governor Robert D. Carey, of Wyoming, an enthusiastic admirer 

 of Roosevelt, showed his interest in the work of the Station by 

 cooperating with Superintendent Horace M. Albright in aiding the 

 Director to visit the Teton National Forest, south of the Park, the 

 Two Ocean Pass region, and the upper waters of the Yellowstone 

 River. The first-hand knowledge gained by this trip, as well as 

 that secured in other parts of the Park, will be of special value in 

 planning for future investigations in this region. Here occurs the 

 Shiras Moose named in honor of Dr. George Shiras, 3rd, a member 

 of our Honorary Advisory Council who has made extensive field 

 studies of this animal. 



The preceding statement indicates only the amount of substantial 

 gifts and assistance which have been utilized, but does not include 

 all that has been available to the Station. This proffered assistance, 

 which for one reason or another could not be utilized, has nevertheless 

 been much appreciated. Thus Mr. W. C. Gregg of Hackensack, N. J„ 

 volunteered to take a Station representative on his exploration trip 

 through the southern part of the Park ; and Mr. Hays offered facili- 

 ties of which full use was not made. 



The Assistant Director, Alvin G. Whitney, was given, during the 

 past summer, a special leave of absence to conduct the " Forest and 

 Trail Camp " for young men and boys in the Yellowstone National 

 Park. His substitute during this absence was Mr. Aretas A.
