PREFACE xxiii 



the coast district and the low country, where the rainy 

 seasons are well marked, there may be a more definite 

 breeding-season, but upon this point we have no exact 

 knowledge, owing to the difficulties of observing game 

 animals in such bushy districts and the lack of data refer- 

 ring to such districts. 



In the preparation of the present work Colonel Roose- 

 velt has written the first draughts of the life-history account 

 under each species, and of the introductory chapters on 

 Game Reserves and on Concealing Coloration. Mr. Heller 

 has prepared the first draughts of the other introductory 

 chapters, and of the technical descriptions (including the 

 nomenclature used, the coloration, and the faunal maps 

 showing the range of each species). But each has reviewed, 

 added to, and assented to the work of the other; and their 

 responsibility for the entire book is joint. 



The Secretary of the Smithsonian Institution, Doctor 

 Charles D. Walcott, has kindly permitted the mammal 

 material in the National Museum to be drawn on freely for 

 study and description, and the data derived from this source 

 have been of invaluable assistance. 



The photographs which have furnished the illustrations 

 have been received from various sources. Many of those 

 taken from life in East Africa and Uganda have been sup- 

 plied by Carl E. Akeley. Doctor William T. Hornaday has 

 donated for use a large number of photographs of the Afri- 

 can animals in the New York Zoological Park under his 

 charge. By far the larger number of photographs of heads 

 of game animals have been received from James L. Clark 

 and represent heads mounted in his studio in New York.
