facilities. During the year 84 regular students were enrolled in 

 the department and 85 Winter Course students, a total of 169. 



(b) Of the 17 projects investigated, many of the experiments are 

 planned to continue for a series of years. They are intended to 

 throw light on the question of heredity, of constitutional vigor as 

 affected by cross breeding, on the influence of the method of keep- 

 ing eggs for hatching, the comparative influence of natural versus 

 artificial incubation, the effect of different conditions of yarding 

 and feeding fowls, and the influence of various methods of rearing 

 chickens. 



(c) Seven thousand and eighty-eight letters have been written 

 by this department during the year including printed postal replies 

 to inquiries for poultry literature. This work takes the entire 

 time of three persons with considerable special clerical help on 

 occasions. On account of lack of funds it has not been possible 

 to develop any co-operative experiments, but one Reading Course 

 Lesson (No. 45, March, 1909) has been prepared and also three 

 lessons for the Rural School Leaflets. Educational Exhibits have 

 been shown at fairs and poultry shows, and during the year mem-

 the State.
