 The noxt year he })e('anie |)erinanently connected with the 

 Department of Vertebrate Paleontology, but continued for 

 some years to collect small mannnals, fi'om time to time, as 

 opportunity offered, for Dr. Allen. In all, he has made 

 twenty expeditions to the Rocky Mountain Region, the last 

 one in 1918, and has been in charge of these parties since 

 1899. In 1907, he accompanied the expedition which, under 

 President Osborn's leadership, explored the fossil fields of 

 Faytam, Egypt. 



Mr. Granger's work in the fossil fields of the West has 

 covered a considerable range, geographically from New 

 Mexico to Montana, and geologically from the dinosaur beds 

 of the Jurassic down to the sands of the Glacial Period. For 

 the past fifteen years his special work has been the thorough 

 exploration of the Eocene deposits of the Rock}- Mountains, 

 in which are found the remains of animals which represent 

 the beginnings of our North American mammalian life. As a 

 result of this work, the American Museum now possesses an 

 unequaled collection of Eocene mammals. Mr. Granger's 

 activity in this field has been of great profit to the Museum. 

 Throughout this pai'ticular work, he has had the constant 

 assistance of Mi'. George Olsen, to whom he attributes much 

 of the credit for his success. 



In 1910, Mr. Granger was appointed Assistant Curator 

 of his department. In 1911, he became Associate Curator, 

 in charge of manmials. His publications have been principal!}' 

 upon the stratigraphy and fauna of the American Eocene.
