PREFACE 



I HAVE been keenly conscious while preparing this volume 

 that only a lifetime of experience in conservation work 

 would give one an entirely satisfactory background with 

 which to solve some of the questions that have been raised. 

 This book is consequently little more than an introduction 

 to the numerous problems that are faced by government 

 agencies in the field of wild-life conservation. I can only 

 hope that it may be of some value to administrators and 

 others who are interested in the preservation of the nation's 

 wild life resources. 



I should like to express my appreciation for the encour- 

 agement, aid and advice that had been given me in the 

 preparation of this study by a host of persons both inside 

 and outside of the government service. I am especially in- 

 debted to Professor Arthur Macmahon of Columbia Uni- 

 versity, who has unhesitatingly given of his time and effort 

 during the past three years, for innumerable corrections in 

 organization and interpretation. 



Professors Luther Gulick, Schuyler Wallace, Philip Jes- 

 sup, Joseph Chamberlain, Howard Lee McBain, and Arthur 

 Burns, all of Columbia, have read the manuscript and 

 offered invaluable suggestions. Professors Oliver Field of 

 the University of Minnesota, Markley Frankham of the 

 Brooklyn Law School, Patterson French of Union College, 

 and Judge Irvine Lenroot of the United States Court of 

 Customs Appeals, have also read portions of the manu- 

 script and made helpful comments.
