panics private ownership. In looking forward towards constructive 

 measures for the proper maintenance of the wild life of our forests, 

 the time is fast approaching when adequate provision should he made 

 for a study of its diseases. 



Fishermen and anglers frequently meet with diseased fish, but at 

 present we know so little about the habits and life histories of 

 disease-producing organisms that we are generally unable to protect 

 our food and game fish. With a view towards making an inventory 

 of the worm-caused diseases of Oneida Lake fish a cooperative 

 survey was arranged between th-^ United States Bureau of Fisheries 

 and the College of Forestry, and Dr. Henry S. Pratt of Haverford 

 College, Pennsylvania, and Mr. Frank C. Baker, then of the College, 

 made a study of the parasitic worms of this lake. The paper by Dr. 

 H. J. Van Cleave is based upon specimens collected by Messrs. 

 Pratt and Baker. Other reports extending these investigations are 

 in preparation.
