DEPARTMENT REPORTS. 131 



A special course of five credits to a large class of Federal students. 



A short course in apiculture running eight weeks was given to Horticultural 



short course students. 

 A short course in the control of fruit pests to Horticultural students. 

 A regular short course to second year students in General Agriculture for 



eight weeks' and for second year men of the sixteen weeks' course. 

 A special course for students in farm business, meeting five times a week 



for four weeks. 



During the spring term the following courses were given : 



Entomology HI Fruit Insects. 



Entomology I Introduction to Study of Insects. 

 Entomology Va and Vb Systematic study of scale-insects. 

 Entomology IXb Apiculture (elective for seniors). 

 Entomology Xa Apiculture (option for beekeepers). 

 Entomology Xd Apiculture (option for beekeepers). 

 Two courses to Federal students, F3 and F6. 



Entomology 101, graduate work in parasitology, was given during the entire 

 year. 



The constantly increasing numbers of Federal students taking apicul- 

 ture has necessitated the establishment of several out apiaries. Some- 

 thing over ninety Federal students have taken work in apiculture during 

 the year. Our quarters are rather inadequate for handling so many 

 extra men and some ingenuity has been uecessary in order to provide for 

 some of the instruction.

 Dear Sir: 



I have the honor to submit for 3^our consideration the following report 

 on the work of the Department of Mathematics for the year ending June 

 30, 1922. 



During the year the teaching statf of the department was as follows : 



L. C. Plant, Professor. 



L. C. Enwnons, G. G. Speeker, S. E. Crowe, Associate Professors. 



F. E. Wood, V. G. Grove, Assistant Professors. 



R. C. Huffer, J, E. Robertson, S. J. Daley, Instructors. 



The success of a dc])artment must necessarily come through its indi- 

 vidual members. No small amount of the eiticiency of the Department of 

 Mathematics is due to the graduate work done by the members of the 

 staff. During the past year Chas, T. Burner, who has been on leave of 

 absence, has done advanced work at Harvard University and Vernon G.
