PREFACE TO SECOND EDITION. 



During the six years since the First Edition appeared, 

 several hundreds of polo ponies have passed through my 

 hands, and I have taken part in many good matches, with 

 the result that I have been able, from practical experience, 

 to bring out this book in a revised and considerably enlarged 

 form.
