Zincing the Ceiling of Engine Room in WiUianis Hall. 



Ill accordance Avitli a resolution of the Board, tlic latliing ^vas removed from 

 the ceiling over the boilers in AVillianis Hall, and zinc put in its place to pro- 

 tect the building from fire. This work was done by the engineer, Mr. George 

 Burdick, assisted by students. Its total cost to the College was $20.44. 



Steam Pump in Williams Hall. 



Since lowering the steam pump three feet as described in the Report for 

 1877, it has done satisfactory work. The total cost of repairs has been $2.00, 

 which was for replaning the valve seats as autiiorized by the Board. Its 

 capacity is about twenty-five barrels per hour, although this to a great extent 

 depends wpou the depth of the river. The pump in its present position is about 

 23 feet above the bottom of the river, and 21.44 feet above the check valve in 

 the inlet pipe near the river. To raise the water 1.44 feet we have depended 

 uiDon a dam of loose stone. This was not sufficient, however, and during the 

 lowest stages of water no pumping could be done. We are now replacing this 

 dam with a more substantial one as shown in another portion of the report. 

 The steam pump is 804 feet distant horizontally from the river. It lifts water 

 by suction about 21.5 feet (depending on the depth of water in the river), and 

 forces the water to the top of the tank in Williams hall, 01.19 feet farther, 

 making a total lift of 82.7 feet vertically, and 804 horizontally. The bottom * 

 of this tank is 19 feet above the upper floor in Wells hall, and 39.63 feet above 

 the bottom of the wind mill tank at the greenhouse. The capacity of the tank 

 is 37 barrels. 



Because of the uncertain and limited supply of water at the greenhouse it 

 has been proposed to connect the pipe recently laid from the water tank in 

 Williams hall to AVells hall with tlie greenhouse water pipes. The estimated 

 cost of such connection would be : 



397 feet of inch pipe - -.. $39 70' 



Extra valves and cost of laying 10 30 



Total cost $50 00 



Wafer Pi2)e Connecting Williams and Wells Hall. 



The bottom of the water tank in Williams hall is 49.4 feet above the lower 

 water table and 19 feet above the level of the ujiper floor of Wells hall. The 

 steam pump is so connected as to pump directly into the tank in Williams hall, 

 which holds 37 barrels. It was seen that by connecting this tank with Wells 

 hall there would be head suflicient not only to supply the boilers in the base- 

 ment with water, but to raise the water to the various floors in the building, 

 thus providing a cheap and efllcient water supply for AVells hall. The pipe 

 which was laid in 1872 between the Laboratory and the boilers of Williams hall 

 for supplying the Laboratory with steam, being no longer used was taken up, 

 a trench between the two halls was dug and the pipe laid in this position. The 

 old pipe not being quite long enough, 75 feet of new pipe were obtained; also 

 two new valves and several couplings, the cost of which was assumed by the 

 boarding hall. In the valley between the two halls was placed a drip valve, so 

 that the water could be emptied from the pipe if necessary. 



The total cost to the College of this improvement was $19.25 for students' 

 labor in taking up and relaying pipe. For want of means the supi)ly pipe 

 was not carried above the basement of Wells hall, but a valve was put in the
