The buildings not already heated by steam are used principally for recitation, 

 and consequently in use but a few hours per day. Under such conditions 

 steam heating can never be as economical as heating by stoves, unless the extra 

 cost of insurance be reckoned an item of the heating. If we figure the cost of 

 insurance as one-quarter per cent less for buildings heated by steam than by 

 stoves, this would lessen the cost of steam heating by about 180.00 per an- 

 num. 



CHIMNEY. 



If the boiler capacity be increased 50 per cent, it will be necessary to in- 

 crease the height of the chimney to the height originally intended, viz : to 90 

 feet. The foundation is ample for that height, the cornice only needs to be 

 removed, and the chimney can readily be extended 25 feet. 



I acted as purchasing agent for about two-thirds of the past year, but at my 

 request I was relieved of such duties by the Board. I adopted the following 

 classification to govern in the purchase of fuel and found it to work very satis- 

 factorily. 



The following classification of wood for fuel is to govern in all contracts made 

 after the date of November 20, 1884 : 



Glass A. — Split body wood of Hard Maple, sawed ends. 



Class B. — Split body wood of Beech or White Oak, sawed ends. 



Class C. — Split body wood of Tamarack, Black Oak, Elm, Soft Maple or Ash, 

 •or round, straight wood of Beech or Maple. 



Class D. — Round wood belonging to Class C, sawed ends. 



No wood accepted unless sound, neatly piled, when wanted, and from three to 

 eight inches in diameter. 



Crooked top wood not accepted. 



WATER WORKS.

I was relieved, at my request, from charge of the fire department by Presi- 

 dent Willits at the beginning of the spring term. Up to that time I had regu- 

 lar fire drill once per week. This drill is now in charge of the military 

 department and will, no doubt, be much more eflicient. 



As engineer of the water works, I call attention to the necessity of extending 

 the works so as to give fire protection to the residence property on the grounds. 

 The State has invested in residences and barns about 143,000 that is wholly
