50 DEPARTMENT REPORTS. • 



Lieut. W. L. Simpson taught trigonometry, fall term, 1888. 



I have taught the following classes: 



Fall term, 1888 — Agricultural engineering and lithology, differential 

 calculus, trigonometry. 



Spring term, 1889 — Surveying, three hours per day ; integral calculus. 



Summer term, 1889 — Strength of materials; astronomy, two hours per 

 day. 



The classes have been on the whole well filled with attentive* and well- 

 prepared students, so that while the year has been a busy one, it has also 

 been a pleasant one. 



STEAM HEATING PLANT. 



Little has been done to this plant except to keep it in repair and to 

 improve its efficiency wherever it had been found defective. 



Mr. James Wiseman, foreman of the iron shops, who has been the efficient 

 engineer for the past four years, was obliged to give up his oversight of the 

 steam works, because of the necessity of giving his full time to the iron 

 shop. Mr. Richard Hiscock was appointed to take charge of the steam 

 works. This he has done very efficiently. 



The steam heating plant is in better condition than ever before, and less 

 and less complaint is heard of poorly heated rooms each year. It has been 

 the policy for the past two or three years to re-pipe each room having a 

 defective heating apparatus as soon as possible after learning its condition. 

 I had all the exposed steam pipes covered with a layer of asbestos paper, a 

 covering of brown paper, and a thick coating of hair felt; the whole was 

 then covered with canvas, sewed in place. The result will be a material 

 reduction in our coal bill. 



HOT WATBE HEATING PLANT. 



The new dormitory, Abbot Hall, was fitted with a hot water heating 

 plant, consisting of a Bolton boiler of three fire pots, and a box coil, with a 

 heating surface of about 1 to 50 cubic feet in each room on the second floor, 

 and 1 to 40 cubic feet in each room on the first floor. The work was done by 

 contract by F. 0. Bennett & Co., of Lansing, for $1,300, and has proved in 

 all respects a success. We covered all the main circulating pipes, as described 

 for steam, during the spring term. 



We have built, and have nearly in place a hot water heater, for the secre- 

 tary's office, to be used during the winter vacation, at which time steam can 

 not be had. We shall also build and put in place a complete plant for heat- 

 ing the new agricultural building during the coming winter. 



BATH HOUSE. 



We have equipped a bath house with ten tubs for the use of the students. 

 The building was heated, supplied with hot and cold water, and the bath 

 tubs set complete by our own men. The job, though a very complicated 

 one, was thoroughly done, and worked perfectly without any remodeling 

 from the first. The estimated cost of the bath house and equipments was 

 $600, of which the students raised $300 as a loan, and the Board appropriated
