ciated with, particular disorders, may do so with profit by obtaining fuller works on the subject. Many scientific workers are devoting their time to the problem of combating diseases among poultry, and assistance is willingly given by officers of the experiment stations to farmers who desire to identify any disease causing loss in their flocks. The practical poultryman will recognize the fact that measures for the control of disease cannot be limited to sanitation and the treatment of sick birds, but, in reality, include such important matters as the selection of healthy stock, intelligent feeding, proper housing, and other details essential to the successful management of poultry. I gratefully acknowledge my indebtedness to the works of Dr. D. E. Salmon and John H. Robinson, editor of Farm Poultry, and to the recent publication on poultry diseases by Dr. Raymond Pearl, Frank M. Surface, and Maynie R. Curtis. My thanks are due to R. S. Martinez for the care taken in making the photographs from which the drawings for the illustrations in the chapter on Post-Mortem Examinations were prepared. Much valuable information has also been obtained from bulletins issued by the experiment stations of the United States and by the Ontario Agricultural College of

Canada.
