KEPOllT OF TKE DEPAllTMENT OF MATlIExMATlCS AND 



ENGINEERING. 



To President Abbot : 



I have the pleasure of submitting the following report of the Department 

 of Mathematics and Civil Engineering, for the year ending August 31st, 1879. 



CLASS INSTRUCTION. 



AVith the present arrangement of studies, each class in the College has at 

 some time during the year, one or more studies in my charge. 



I teach to the Seniors, Civil Engineering, Drawing and Astronomy ; to the 

 Juniors, Mechanical Physics ; to the Sophomores, Mechanics, Surveying, and 

 Trigonometry; to the Freshmen, Algebra, and Geometry. The past year, 

 owing to the absence of a Junior class for two terms, there has been no class 

 in Drawing. 



The number of hours devoted to instruction in the class-room has averaged 

 3^ each day, this however is only a fraction of the actual time used in prepa- 

 ration for class instruction. Besides the class instruction, much time of neces- 

 sity has been given to those operations of practical engineering which have 

 been in my charge. 



The number of students that received instruction in my classes has been 

 as follows : 



Civil Engineering 32 



Astronomy 27 



Algebra (first term) — 67 



Algebra (second term) 75 



Geometry (first term) 63 



Trigonometry 62 



Surveying 61 



Mechanics (one division) 22 



The course of instruction has been the past year, except for the study of 

 Mechanics, the same as for the year ending August 3ist, 1878, and as described 

 in my report for that year. In Mechanics, Peck's work was substituted for 

 that of Olmstead. The class completed the text-book, and in addition had a 

 short course of lectures on optics and acoustics. 



In addition to the class instruction the following operations in Practical 

 Engineering were in my charge. 



SURVEYING. 



In field No. 4, drains sufficient for thorough drainage, have been located 

 and surveyed. 



For tlie purpose of draining the area embraced in fields Nos. 12, 13, 14, 15 

 and 16, a main drain to be constructed of 8-inch tile, has been located and 

 surveyed. This drain terminates in the Red Cedar River, and crosses fields. 

 No. 6. No. 8 and No. 10. To locate this drain required extensive surveys of 

 the whole area to be drained, and also of the territory lying between this area 

 and the river. Although the route chosen presents many difficulties of con- 

 struction, it is believed to be the most favorable route possible. The main 

 drain commences in a silt basin in the northwest portion of field No. 12, with 

 a depth of 4 feet. The average depth of tlie main drain from the silt basin
