any, is into the coil room, and not into the storage 

 room. The perforations for outflow of air from cold 

 air duct, a a, are twice as numerous on bottom as on 

 the top, and some are placed in the face or side of 

 duct also. The perforations are comparatively small 

 holes placed quite near tog-ether, obviating- all strong- 

 drafts, and at the same time insuring- a very pene- 

 trating- circulation which will not allow of any dead 

 corners. The false ceiling- is perforated likewise, the 

 holes being- most numerous throug-h the center of 

 room at farthest point from cold air ducts, and more 

 widely separated as they approach sides of room 

 directly over cold air duct. If air ducts are correctly 

 proportioned, the perforations properly located and of 

 correct size, and eg-g-s are piled uniformly from side 

 toward center of room, the air is forced to percolate 

 throug-h the piles of eg-g-s where its presence has such 

 a salutary effect, for reasons already discussed. The 

 exhauster for handling- the air can be placed in almost 

 any location handy to power, and the air conducted to 

 it, but a more desirable arrang-ement is a direct con- 

 nected or a direct belted electric motor. Then the 

 fan may be placed advantageously to get direct and 

 shorter air ducts, saving both space in the storage 

 room and expense in construction. 



A saving of space can be obtained by using this 

 tiois tern a ~ system of air circulation, amounting in some cases to 

 fully 10 per cent of the total space cooled, and a sav- 

 ing of 5 per cent can be had in any house, if skill and 

 care are used in arranging cooling coils and air ducts. 

 Where rooms are moderately high the space over a 

 hallway or corridor may be utilized for cooling coils. 

 As the cooling coils are located entirely outside of the 

 storage room proper, the room itself can be filled 

 with goods snug up to the false ceiling at the top and 

 against air ducts on sides. The side ducts and false 

 ceiling only occupy about two inches of space in their 

 respective locations, so the space occupied by the air
