VI PREFACE. 



I rcyrci iliai I have been unable to give the book a more scientific aspect. The 

 vvti..!.- of it was written in the field, and so books of reference were an impossibility. 



1 must here acknowledge my indebtedness to those friends who have given me 

 photographs or rendered me other help. 



Kspecially are my most grateful thanks due to my aunt, Mrs. Edgar Clark, for 

 the patience and skill with which she has cajoled my ill-taken films into revealing 

 what they really saw through the camera's eye. I feel sure that whatever success 

 this book may achieve will largely be attributable to her valuable aid in connection 

 with it. 



Unfortunately mv friend, U. D. Lyell, with whom 1 collaborated in my book on 

 Central African Game, has been unable to work with me again. He has very kindly, 

 however, made out the reduced drawings of spoor to be found in Chapter VIII.
