PREFACE. 15 



by Dr. Tarleton H. Bean, the well-known fish culturist ; the article on 

 "The Scarcity of Ruffed Grouse in 1907," by E. S. Woodruff, M.F., a 

 forester and ornithologist ; and the interesting monograph on the " Epi- 

 demic among Trout at Cold Spring Harbor," by M. C. Marsh, of the 

 United States Bureau of Fisheries. Attention is also called to the 

 report of Dr. Richard M. Pearce, of the Bender Laboratory, on an 

 investigation of the mortality among Adirondack deer, and the review 

 of this report by Dr. Samuel B. Ward. 



Favorable mention is also due the artistic colored plates by Den- 

 ton, Rhead, Thompson-Seton, and Gillette ; and the superior gelatines 

 by Watson. Without these illustrations the report would not only have 

 been incomplete, but would have lost much of its educational value. 



THE COMMISSIONER.
