DEPARTMENT REPORTS. 



Michigan Agkicultdkal College, ) 

 October 1, 1886. j 



To President Willits : 



Dear Sir : — I have the honor to submit the following report of the various 

 repairs and interests not educational, in charge of the engineering department,, 

 for the year ending September 30, 1886. 



Respectfully, 



R. C. CAEPENTEE, 

 Professor. 



REPAIRS OF BUILDINGS AND STEAM WORKS. 



For these repairs Ave are organized as follows : I act as superintendent an(J 

 engineer ; Mr. James Wiseman, assisted by Eichard Hiscock and sundry stu- 

 dents, makes repairs in iron ; Mr. H. Campbell, assisted by students, makes 

 repairs in wood. At present repairs are done only by written request of the 

 Secretary of the college, except such as pertain directly to the engineering de- 

 partment. In addition to repairs quite an amount of new work and improve- 

 ments are done. 



Although the repairs as a rule have been promptly done, it will no doubt 

 give better satisfaction if they can be separated from the workshop of the me- 

 chanical course. 



Some changes will have to be made in the steam works in order to secure 

 more efficient heating, especially in Wells and Williams halls. With four 

 boilers, each four feet in diameter and 12 feet long, we have been heating one 

 and one quarter million cubic feet of space, situated at an average distance of 

 about 450 feet, besides pumping each day about 8,000 gallons of water to an 

 elevation equivalent to 90 feet in height, and 4,000 gallons to an elevation 

 equivalent to 40 feet in height, besides furnishing steam for a 12-horse-power 

 engine, run on the average seven hours per day. This has been accomplished 

 only with the utmost difficulty and by an uneconomical use of coal. To fur- 

 nish the necessary steam economically, we should have at least 50 per cent- 

 more boiler capacity. 



The following tables exhibit the main points of our heating system :
