when free of eggs. This latter arrangement, of 

 course, requires more space and is slightly objection- 

 able on this account. The circulation is more vigor- 

 ous with this system than with any pipe-in-the-room 

 system, depending- on the law that the higher the 

 column of air the stronger the draft, on the same 

 principle that a tall chimney gives 

 greater draft than a short one. It is, 

 therefore, better than any room pip- 

 ing, and has the added advantage of

being easily shut off from the room, when the weather 

 no longer requires cooling power. The need of keep- 

 ing the air of the room from contact with the frost 

 on pipes will be looked into under ventilation and 

 absorbents. 



Refrigerator rooms for the storage of eggs should 

 not exceed thirty or thirty-five feet in width. The 

 cross-section illustrations of rooms cooled by gravity 

 air circulation, which have already been illustrated, and 

 the two sketches shown herewith of the arrangement 

 of air distributing ducts used in two systems of forced 

 circulation, are sufficient to show why a room should 

 not be excessively wide as compared to its height. In 

 a wide room it may be seen that the air from cold
