414 Roosevelt Wild Life Bulletin 



The photographs accompanying this article were for the mosr 

 part taken by the author with the naturahst's graflex camera which 

 Mr. Kermit Roosevelt used during his expeditions with his father 

 to Africa and South America, and which he generously loaned for 

 the present study. Figure 52 has been reproduced already in The 

 Minds and Manners of Wild Animals by Dr. Wm. T. Hornaday, 

 p. 130, 1922; figure 61 has appeared in The World's Work, Vol. 45, 

 p. 109, Nov., 1922; and figure 92 was published in Natural History, 

 Vol. 22, No. 3, p. 230, 1922. A number of original photographs 

 secured by other observers, and kindly furnished for use in this 

 paper, have been duly credited to them. 



I am greatly indebted to Air. Milton P. Skinner, until recently 

 official Park Naturalist, for numerous suggestions and points of 

 fact drawn from his twenty-five years of painstaking and accurate 

 records of Yellowstone mammals. Also to Mr. Edmund J. Sawyer, 

 present Park Naturalist, from whose drawings, based on two sum- 

 mers' observations of the Yellowstone bears, plates 25 and 26 have 

 been reproduced. 



Finally, grateful acknowledgement is here made to those who 

 generously contributed the funds that made possible this preliminary 

 survey of the big game of the Park. An anonymous friend of 

 Colonel Roosevelt and of the Station donated $1000 to defray ex- 

 penses of the field work. Mrs. Corinne Roosevelt Robinson, who 

 had accompanied her brother Theodore Roosevelt on one of his 

 expeditions to Yellowstone Park, also contributed. The initial sup- 

 port for this project came from Mr. Howard H. Hays whose camps 

 furnished us board and lodging without charge during the tourist 

 season. The warm interest of all who cooperated in one way or 

 another is deeply appreciated by both the author and the Roosevelt 

 Station. 



GRIZZLY BEAR OR SILVERTIP 

 Ursiis horribilis imperator Merriam 



The sight of a wild free grizzly bear in the Yellowstone excites 

 more awe and admiration in us than does that of any other wild 

 animal. It is here still possible for the tourist to behold that most 

 feared of all American animals, the grizzly or silvertlp in his native 

 wilderness. Every evening at sunset you w411 find gathered on the 

 slope above the Canyon Hotel garbage dump a large party of people, 

 waiting hushed and excited, to get a glimpse of the grizzlies coming 

 to their favorite feeding place. To see the great bears suddenly 

 emerge from the forest in the dusk and come galloping along, their
