Acknowledgments 



I wish to express my great indebtedness to the New York State 

 Conservation Department, and particularly to (former) Commis- 

 sioner Lithgow Osborne and Director of Fish and Game, WilHam 

 C. Adams, for their sympathetic encouragement in this work. Full 

 credit for data used from the New York studies rests with the Con- 

 ser\^ation Department. All New York records cited are derived from 

 the Conservation Department's Annual Reports, unless otherwise 

 noted. 



To my former colleagues I express my unbounded gratitude for 

 many years of stimulating and productive collaboration in "roughing 

 it with the ruffed grouse." Those whose association with me has 

 extended over most of the past decade or more and to whom I am 

 most grateful are Gardiner Bump, Robert Darrow, Walter Crissey, 

 Victor Skiff, Ben Bradley, Robert Cameron, Arthur Holweg and Asa 

 Smith. 



For writing the greater part of the chapter on grouse management 

 that deals with the propagation of woody plants, I am indebted to 

 Robert Thornton, formerly of the U. S. Soil Conservation Service.
