Banding sick duclis prior to placing them in recovery pen for observa- tion. Hollywood Gun Club, Kern County, California, October, 1928. Photo- graph by B. S. Cheney Foundation for Medical Research directs investigations relating to the disease of game and fish, and furnishes laboratory facilities. Paul A. Shaw, with an assistant, has been endeavoring to find out the cause of duck disease. He has made numerous trips into the field, including Klamath Lake, Hollywood Gun Club, Kern County, Salton Sea, and Bear River marshes, Utah, gathering evidence. By means of numerous experiments on live birds he has been able to discount theo- ries based on the idea that the disease is a contagious one caused by bacteria. Mud and water gathered at places where the disease occurs regularly and from places where the disease is not known, when analyzed gave information as to salts that might be concerned. The toxic effect of numerous chemicals has been tried out and it is believed that eventually it will be possible to produce the disease artificially in the laboratory. Three chemical papers giving the result of these studies have been published in the Proceedings of the Society for Experimental Biology and Medicine, under the general heading of '' Duck Disease Studies:" 1. Blood Analyses in Diseased Birds; 2. Feeding of Single and Mixed Salts; 3. Salt Content of Soils in Diseas
