ICE HOUSES AND 



The foundation and floor are made of concrete placed 

 upon a well compacted sub-base of cinders or gravel. On 

 this base a four-inch concrete floor is placed. The founda- 

 tion wall is ten inches thick with a sixteen-inch footing. 

 Both the cold storage room and the ice bunker are provided 

 with drains, the one in the ice bunker being trapped to pre- 

 vent the circulation of air. The concrete floor in both 

 rooms slopes one-quarter of an inch to the foot toward the 

 center, causing the water to drain off readily and prevent- 

 ing unnecessary wasting of the ice. Two-inch by six-inch 

 floor joists are placed in both rooms to permit the free cir- 

 culation of air between the ice bunker and the cold store 

 room. A floor of matched lumber is laid on the joist in 

 the cold store room to within six inches of both walls, these 

 openings being left for the circulation of air. 



The walls are made up of 2x8-inch studding to both 

 sides of which two layers of matched lumber are nailed. A 

 good grade of waterproof paper is placed between both 

 layers of matched lumber to prevent air and moisture enter- 

 ing the space between the studding. This space is then filled 

 with mill shavings, packed in at the rate of eight or nine 

 pounds per cubic foot. The ceiling construction is exactly 

 the same as that used in the wall except that 2x6-inch joists 

 are used in place of the 2x8-inch studding. The ice is put in 

 through a trap door which is placed in the ceiling just inside 

 the ventilator. This door is closed tightly after the ice 

 house is filled and need not be opened until the following 

 season at filling time. The 2x8-inch ridge piece projects 

 beyond the end of the building to provide a place for fasten- 

 ing a block and tackle to be used when the ice is harvested. 

 The roof is one-quarter pitch made up of 2x6-inch rafters 

 one-inch sheathing, and shingles placed over both the cold 

 store room and ice storage room. It will be found some- 

 what of a saving to use the "lean-to" construction rather 

 than to cover the entire building with one gable roof as the 

 amount of siding and length of studding is reduced.
