DEPARTMENT REPORTS. 107 



Since these various groups came at different periods of the day, ad- 

 (Htional teaching help was required to handle these war courses 

 efficiently. To meet this need the Botany Department very kindly offered 

 to the Physics Department the full time services of Dr. Woodcock and 

 Dr. De Zeeuw. This offer was accepted. At the same time we also 

 gave the regular courses, Physics Id and Physics 2d, all of which made 

 for us an exceptionally heavy schedule of work. 



The department made a still further contribution to the war program 

 of the College. At the request of Captain Henderson and Lieutenant 

 Bridgman of the Infirmary, it did skiagraphic X-Ray work for the several 

 detachments, with apparatus made and assembled in the department 

 except for a discarded hydrogen X-Ray tube. 



At the beginning of the winter term it was found expedient to repeat 

 the usual fall term's work in addition to the regular winter term's work 

 to be given, in order that the students then entering college would be able 

 to finish their regularly scheduled work at the end of the Summer School 

 thus permitting them to graduate with their respective classes. 



During the spring term it also became necessary for the same reason 

 to give both the winter and spring terms' work simultaneously. 



On September 1st the Physics Department sustained a great loss in 

 the resignation of one of its members. Professor O. L. Snow, who had ren- 

 dered very faithful and efficient service for eight years. Mr. Snow left to 

 accept a position with the United Engine Company, Lansing, ]\Iich., to 

 which was attached a salary of nearly double that which he received 

 from the college. 



Mr. E. A. Armstrong, an AL A. C. graduate of the Class of 1911, 

 Electrical Engineering Course, was hired to fill the position made vacant 

 by the resignation of Prof. Snow. He in turn resigned at the end of the 

 winter term to accept a more lucrative position with the National Machine 

 Products Company of Detroit, Michigan. 



No one was secured to fill the position vacated by Prof. Armstrong. 

 The part time services of Assistant Prof. P. G. Andres were loaned to the 

 Physics Department by the Department of Electrical Engineering, to han- 

 dle the engineering physics courses, Physics 2e and 2f, previously taught 

 bv Professor Armstrong. He was assisted in this work bv Mr. R. J. Bondie 

 of the class of 1918. 



Due to the conflicts in schedules caused b}^ the doubling of the work, 

 we were obliged to employ student laboratory asisstants for part of the 

 work throughout both the winter and spring terms. 



The number of students per tei-m enrolled in physics was as follows: 



Summer School, 1918 18 



Fall Term, 1918— 



S. A. T. C. Students 201 



Regular Students 11 



Total 212 



Winter Term, 1919 179 



Spring Term, 1919 173 



Total for the ye&v 564
