DEPARTMENT OF AGRICULTURAL CHEMISTRY. 



The work for the past year has been about equally divided between 

 teaching and experimental work. 



Teaching Work, 



In the teaching department, instruction was given to 48 regular students 

 of the sophomore year during one term (the instruction included 

 laboratory practice twice a week). A separate course of lectures was 

 given to about 75 special students. During the winter-course, 125 students 

 attended a course of lectures arranged for them. The separation of the 

 special and regular students sems to be very satisfactory, allowing a more 

 advanced grade of work to be given to the regulars. 



Experimental and Extension Work. 



The experimental work, which is conducted under an appropria- 

 tion from the State fund, has consisted chiefly in making chemical 

 analyses of materials sent in by other departments. A large number 

 of moisture determinations have been made of crops grown for ex- 

 perimental purposes. The requests for analyses of various materials, 

 as soils, fertilizers, feeds, insecticides, from the residents of the State, 

 is increasing rapidly and now takes most of the time of the assistant 

 in the laboratory. This work is done as part of the extension work of the 

 department. 



Some preliminary work was done on the moisture and sulfur con- 

 tent of evaporated apples, but time and material were not sufficient 

 to warrant publication. It is planned to continue the Avork this fall. 

 If the coming year brings an increase of students and any marked 

 increase in the demand for analytical work, the facilities of the de- 

 partment will be taxed, and increased room and assistants will be 

 necessary.
