EGGS IN COLD STORAGE. 19 



possible, those who were making* tests of air moist- 

 ure, and get opinions on the correct humidity for a 

 given temperature. The following- are the queries: 



First. What tests, if any, have you made of the 

 dryness or humidity of your egg rooms? 



Second. What per cent of air moisture do you find 

 gives the best results at the temperature you use? 



Third. What instrument do you use for testing 

 air moisture? 



Questions 1 and 3 are practically the same, the 

 latter being written simply to make the query more 

 plain and indicate whether an instrument or some 

 other test was used for determining air moisture. 

 Four houses reporting are using the dry and wet bulb 

 thermometers; the others are using hygrometers of 

 French or German make. 



The answers to question 2 vary greatly ; some 

 also giving the actual testing humidity of their rooms humidity. 

 and their opinion of a correct degree as well. From 

 70 to 80 per cent of humidity is the test of nearly all 

 reporting, and of the rooms tested by the writer, 

 nearly all show a similar humidity, with one occasion- 

 ally going as high as 85 per cent, and some as low as 

 65 per cent. Two answers recommend a humidity 

 of 65 per cent, and one a humidity of 60 per cent, 

 with a temperature of 30 F. to 32 F. Others hold 

 that their testing humidity of 70 to 80 per cent is 

 correct. The matter of correct humidity will be dis- 

 cussed further on. 



The humidity of a room depends on the season 

 a moderate extent, and the condition of the room, as humidity. 

 regards ventilation, in some cases. In late fall or 

 winter, especially, if air is taken directly into the 

 room from the outside, the humidity will be low. As 

 cool weather approaches, the tendency is for the 

 humidity to rise, and unless kept down by ventilation 

 or by the use of absorbents, serious consequences are 

 sure to follow.
