ICE-HOUSE AND COLD BOOMS. 



This ice-house has been well tested, having preserved its store 



of ice for two years at a 

 time. Having been erected 

 for the use of a public 

 building, its size is per- 

 haps greater than would 

 be necessary on an ordi- 

 nary farm, but its dimen- 

 sions may be altered to 

 suit circumstances if the 

 proportion of the different 

 parts be very nearly ad- 

 hered to. 



The ice room is 16 by 

 16 feet and 12 feet high 

 in the clear. The cold 

 room under the ice room 

 is of the same size as the 

 latter on the floor, and 7 

 feet 6 inches high in 

 the clear. In addi- 

 tion to the cold room below, there are two apartments or pas- 

 sages surrounding the ice room which serve the two-fold purpose 

 of preserving the ice from the exterior heated air, and giving 

 additional room for cold storage. The width of these inclosing 

 passages is 4 feet, and their bights are 8 feet and 9 feet 6 inches 

 respectively. They are sufficiently wide for a series of shelves 

 tipon one side of each throughout, which gives a very useful ex- 

 tent of shelving room. 



The entrance to these apartments is by the door. The ice is 

 received at a high door at C, Fig. 2. At E, Fig. 2, are windows 

 to light the passages, etc., and at F, Fig. 2, are placed the stairs 

 by which access is obtained to the ice room and to the upper part 

 of the inclosing space. The studding of the interior frame is 

 3 by 12 inche *, that of the exterior frame is 3 by 10 inches, and 

 the spaces bet wen the studding are filled with saw-dust. The 

 space under the lower floor is filled with wood shavings. The 

 floor and ceiling joists also have their spaces filled with sawdust. 

 At G, Fig. 2, is a ventilator shaft, and at H a girder. The window 

 sashes are double, and the doors have canvas linings packed 

 with sawdust to make them of the thickness of the frame. The 

 excavation is about 2 feet below the surface. A drain was pro- 

 vided extending from the center of the building under the lower 

 floor to the sewer and trapped. [R. G. Hatfield, New York City.
