DEPARTMENT OF MATHEMATICS AND CIVIL ENGINEERING. 45 



class in integral calculus. Sophomores, one class in trigonometry, two 

 classes in algebra and one class in geometry. Freshmen, two classes in 

 algebra and a preparatory class in arithmetic. Total enrollment, 212. 



Sprimj term, 1893. Seniors, one class in civil engineering. Juniors, 

 one class in mechanics of engineering. Sophomores, one class in analytic 

 geometry, and one class in surveying, with afternoon practice in the field. 

 Freshmen, 1 class in geometry and three classes in algebra. Total enroll- 

 ment, 206. 



Several subjects have been added to the list taught by this department. 

 Among the elective courses offered to seniors in agriculture, is one calling 

 for two terms' work with us. The first term's work is in civil engineering, 

 so called, but is properly an extension of the earlier work in surveying, and 

 is largely preparatory to the second term's work under the title of agricult- 

 ural engineering. The latter embraces principally so much of the 

 engineering operations connected with land drainage, road construction 

 and the building of ordinary highway bridges, as is possible to include in 

 a term of twelve weeks, one hour daily. The subject of hydraulics is 

 inserted in the new schedule of studies as an elective subject for mechani- 

 cal seniors, and solid analytic geometry is displaced by graphic statics. 



EQUIPMENT. 



There has been few additions to our instrumental equipment during 

 the year. Several surveying instruments have been overhauled and 

 repaired by the makers, and we have made for our own use eleven iron- 

 shod rods or " flags," and two stadia rods. Through the kindness of the 

 Artificial Stone Co., of Lansing, we acquired by gift an assortment of drain 

 tiles, sewer pipes and cement pipes, both straight sections and specials, to 

 be used for illustration in the engineering classes. The above, with a 

 slide rule of latest design and a few small tools, constitute all additions 

 and improvements made up to the date of this report. 



As stated in my last annual report, an appropriation of $300 was made 

 early in the year by the Board of Agriculture, for the purchase of books 

 by this department for the general library. Of that sum, $217 was care- 

 fully, and, I think, judiciously expended. The remainder of the sum 

 appropriated was withdrawn from availability in December, 1892. 



PRACTICAL ENGINEERING. 



The plans for the sewerage of the college grounds, first submitted about 

 a year ago, have been extended, and the lines are staked out in anticipa- 

 tion of a favorable consideration of the plans by the board. A small map 

 of the grounds and farm has been prepared for the use of the board. Plans 

 for the drainage of the cellar of Howard Terrace, and sewerage for the 

 same building, have been submitted. 



In conclusion, let me thank you, sir, for your continued help and sup- 

 port, and acknowledge my many obligations to you for assistance in mak- 

 ing the past year a prosperous one for the department. 



All of which is very respectfully submitted,
