THE DAIRTMAK'S MAN'UAL. 



The spiral galvanized water spouting for buildings serves 

 excellently for this purpose. These pipes are brought 

 along the bottom, as sliown at figure (jG, which is an up- 

 right section, and open into the creamery on each side 

 of the cold pool. The current of air which passes 

 tlirough these pipes of course melts and uses up the 

 ice and causes a quantity of cold water to be produced 

 which must be drawn off, or the whole body of ice would 

 rapidly waste. The floor of the ice-house is made to 

 slope a little from each side to the center, and the center 

 slopes to the front just enough to cause the drainage to 

 flow into a pipe provided to receive it. This pipe is 



protected by a fine wire- 

 gauze covering to prevent 

 the packing from being 

 washed away. The pipe 

 is carried down through 

 the ground and made to 

 discharge at the bottom of 

 the pool. This is impor- 

 tant, for if it discharged 

 into the top, air would 

 pass into the ice through 

 it and waste it considera- 

 bly. The outlet of the pipe being always covered with 

 water prevents any access of air through it. 



At figure 67 is shown the front view of the wall of the 

 creamery 'with the openings of the cold-air pipes and the 

 tank between them. On one side may be made a refrig- 

 erating closet for keeping butter in, or one may be made 

 on each side if desired. This provides cold storage of 

 the most effective kind for a dairy and for keeping eggs 

 for sale in the winter. This may be made of sheet iron 

 nailed on the inside and outside of the studding and also 

 overhead, and painted outside with brown mineral paint 

 and white within. The roof of this closet should slope
