REPORT OF THE DEPARTMENT OF MATHEMATICS AND ENGINEERING. 



President Oscar Clute: 



I have the honor to submit the following report for the Department of 

 Mathematics and Engineering for the school year of 1888 and 1889 : 



The resignation of Prof. L. G. Carpenter to take the chair of Engineering 

 in the Colorado Agricultural College, and of Assistant J. B. Cotton to enter 

 on the practice of law at Duluth, Minn., made it necessary to re-organize 

 the department to some extent. Mr. Frank Hall and Mr. Henry Tburtell, 

 both graduates of the class of 1888, were engaged as assistants in the depart- 

 ment, and entered upon duty with the beginning of the fall term of 1888. 

 Both these young men have succeeded nicely in the work for which they 

 were engaged, and have been useful and valuable assistants. Mr. Hall taught 

 the following classes: Fall term, freshmen algebra, three hours per day. 

 Spring term, freshmen geometry, three hours per day, besides assisting in 

 field work in surveying; summer term, freshmen geometry, three hours 

 per day, assisted in laboratory of strength of materials. 



Mr. Thurtell taught classes as follows: 



Fall term, 1888 — Sophomore algebra, three hours per day. 



Spring term, 1889 — Trigonometry, one and one-half hours per day; field 

 work in surveying, two hours per day. 



Summer term, 1889 — Analytical geometry, one hour per day; assisted in 

 astronomy two hours per day.
