unprotected from fire. During the extreme dry weather of the past summer 

 most of the wells and cisterns in the west portion of the grounds were dry and 

 the fire risk was exceedingly great. The cost of giving these buildings protec- 

 tion will be small, as the college has ample pumping facilities. What is needed 

 is simply an extension of the main water pipe. For this purpose will be required 

 108 rods of 6-inch pipe, worth, in place, $13 per rod ; 8 hydrants, worth 150' 

 each ; 40 rods of 4-inch pipe, worth $? per rod — specials and value, $150. 



The total cost would be $2,284, or about o per cent, of the value of the prop- 

 erty protected. 



There is also very much needed one additional hose cart, 300 fe^t of 2^ inch 

 hose, 12 fire plugs in Williams, Wells and College Halls and the Library build- 

 ing, 500 feet of 2^ inch pipe, also 25 small hydrants for lawns. 



The cost of these items, which are needed to put the fire department in effi- 

 cient shape, would be less than $1,000.

To President WilUts : 



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

 given in the Department of Mathematics and Engineering for the year ending- 

 Sept. 30, 1886. Respectfully, 



R. C. CARPENTER, 



Professor, 



recitations and class work. 



« 



During the Fall term of 1885 I taught classes in Agricultural Engineering 

 and Drawing. 



During the Spring term, 1886, I taught classes in Civil Engineering, Draw- 

 ing and Surveying for the whole term, and in Geometry for a portion of the 

 term. 



During the Summer term I taught Drawing two hours per day. 



Mathematics. — Professor Lewis McLouth taught Sophomore Algebra during 

 Fall term 1885, and Trigonometry during Spring term 1886. Prof. L. G. Car- 

 penter taught during Fall term 1885, Free-hand Drawing and Freshman Alge- 

 bra. During Spring term 1886 he taught Free-hand Drawing and Geometry, 

 and during Summer term, Geometry; having on the average for the year three 

 and one-third recitations per day. For Fall term 1886, Prof. L. G. Carpenter 

 has Algebra, two classes, Drawing, one class. Mr. J. B. Cotton has three 

 classes in Freshman Algebra. I teach Agricultural Engineering and Mechan- 

 ical Drawing. 



For class instruction there are very much needed one additional surveyor's 

 compass, several chains, two sets of pins, a pair of steam engine indicators and 

 a small testing machine. 



For the use of the drawing class there is needed a number of copies and 

 models 



Additional class room is very much needed for the classes in drawing and 

 engineering. 



An addition to the Mechanical Building 36x60, and two stories in height, 

 adjoining the present building on the northeast, would afford the necessary 

 room for the classes in mechanical physics in the first story and in the base-
