CONSTRUCTING A COLD STORAGE HOUSE. 



INCE a good many of our most enterprising fruit growers 

 are considering the advisability of building cold storage 

 houses, in order to prolong the season of certain perishable 

 fruits such as Bartlett pears, we give an article which 

 recently appeared in the American Agriculturist, with the 

 engravings : 

 As usually constructed, cold storage ice houses are built 



with two stories ; the first story for the keeping 

 of goods, and the second being filled with ice. 

 The floor between is arranged with openings 

 through which the air, chilled by contact with 

 the ice, descends into the room. A flue is pro- 

 vided to conduct the warm air to the upper 

 part of the ice chamber. It is dried by con- 

 densation of its vapor, and purified by contact 

 with the ice, as it descends on being chilled. 

 Drains with traps are required to carry off the 

 meltage water, and to secure the water condensed 

 from the warm air. I )ampers, in the cold and

warm air flues, assist in controlling the 

 circulation, and ventilators placed in the 

 roof keep the loft free from dampness. 



The walls, ground floor and ceiling are 

 constructed as nearly non-conductive of 

 heat as practicable. No cracks or any 

 channels through which warm or cold air 

 can pass are permissible. Drains, which 

 carry off the water, are securely trapped 

 to keep out the air. Vestibules with 

 perfectly fitting doors are placed at all 

 entrances. Windows are fitted with three 

 or four sashes and air spaces between. 

 Dryness in the storage room is secured 

 by a sheet metal floor under the ice,
