EGGS IN COLD STORAGE. 83 



from the egg's. As pointed out elsewhere in these 

 articles, humidity and circulation have much to do 

 with the evaporation from eggs; in fact, are more of 

 a ruling factor than the package, although the package 

 necessarily has much to do with it. A tight package 

 will allow of less evaporation than an open one. In a 

 very dry room with a vigorous circulation a moder- 

 ately tight package is the thing, but in a compara- 

 tively moist room with poor circulation the more open 

 the package the better. 



An appreciation of the poor circulation and damp storing eggs m 



r r f trays or racks. 



air of the overhead ice systems has caused many of 

 their operators to resort to the use of open trays or 

 racks for the storage of eggs. Very palatable eggs 

 have been turned out in this way, but the use of trays 

 in any ammonia or brine cooled room would lead to 

 very excessive shrinkage of the eggs and consequent 

 heavy loss in candling. On a commercial scale, too, 

 the storing of eggs in trays is hardly practicable, as 

 it increases the risk of breakage immensely, and the 

 eggs must be transferred from the cases when re- 

 ceived at the storage house, and back into cases again 

 when shipped, involving much labor, and perhaps loss 

 of valuable time at some stages of the market. In any 

 but a very moist room, eggs stored in open trays, in 

 bulk, will lose much from evaporation, and the loss 

 will be proportionately higher than on an equal grade 

 of eggs stored in ordinary cases and fillers. The ad- 

 vantage of trays, if any, for some houses, is that con- 

 tamination from fillers is avoided, and about 40 per 

 cent more eggs can be stored in a given space. The 

 eggs are, however, more liable to must as a result of 

 moisture condensing on their surface with change of 

 temperature, or on the introduction of warm goods 

 into the storage room. 



The material used for forming a cushion in the 

 case on top and bottom of the fillers to protect the 

 eggs from contact with the case, and so that they will
