AGRICULTURAL CHEMISTRY. 



I. TEACHING. 



Fourteen (14) students pursued graduate work in agricultural 

 chemistry. One hundred seventy-five (175) undergraduates were 

 registered in the regular courses. Fifty-nine (59) students regis- 

 tered in the special course and one hundred seventy-two (172) In 

 the winter-course sections. 



This makes a total of 420 students who took agricultural chem- 

 istry. 



The instruction was given in five (5) lecture courses and four 

 laboratory courses. 



II. INVESTIGATION. 



Two lines of investigation have been conducted. The first was 

 a continuation of the study of the moisture content of evaporated 

 fruits. This is being done in connection with the evaporated fruit 

 industry of the state. The second is an investigation into the 

 chemical composition of hens' eggs, with special reference to the 

 chemical changes taking place during incubation. It is hoped 

 that some light may be thrown on the functions of the different 

 constituents of the egg in incubation. This work is being done in 

 co-operation with the Department of Poultry Husbandry. 



III. EXTENSION. 



The Department of Chemistry aims to do most of its extension 

 teaching through the work of its laboratory. To this end it works 

 in co-operation with the other departments of the College, and 

 also does some vv'ork directly for the people of the state. Numer- 

 ous inquiries are received for chemical information on various ag- 

 ricultural materials. The following list shows the kinds and 

 amounts of material examined during the past year.
