able to put these investigations before the public, and I therefore, take 

 pleasure in acknowledging my gratitude to all who have aided me. 



To my old friend, Dr. H. H. Claussen, I am indebted for his 

 careful instruction regarding the anatomy and make-up of the horse; 

 and to J. P. Patery, a skilful and intelligent horseshoer of Oakland, Cal., 

 for much practical advice and for his very efficient services at all times. 

 For the diligent and successful efforts in the training and driving of 

 the horses under observation, I am also indebted to Howard L. Franklin, 

 of Syracuse, N. Y., K. O'Grady and sons, of San Mateo, Cal., and to 

 C. B. Bigelow, of Woodland, Cal. 



Furthermore, I take occasion to acknowledge my obligation to 

 I. B. Dalziel, T. W. Barstow, O. V. Greene, "The Horse Review," 

 Ted Hansom, and Schreiber & Sons, and M. H. Reardon, for their 

 courtesy extended regarding the use and reproduction of some excel- 

 lent photographs ; and I also wish to express my thanks to George W. 

 Ellis for his painstaking efforts and for his advice in the matter of 

 illustrations, and to Dwight L. Hackett last but not least for his 

 suggestions in presenting this book to the public.
