Mr. Hopkins : I don't think there would be any effect. I 

 have put ammonia in the cream itself and had no effect. Pos- 

 sibly if we had the whole contents of the reservoir in the fac- 

 tory it might do some harm. 



The Chairman: Ammonia is verj volatile — escapes very 

 readily. 



Mr. Perriam: You spoke of excessive moisture. Don't 

 you have to take uj) that excess with some absorbent? 



The Chairman: When we use ice, you understand, it is 

 carried and deposited on the ice, if there is a circulation of air 

 through the cold room. 



Mr. Wentworth: The moisture assists in holding the ice 

 and reducing the temperature. 



The Chairman: I have seen cold rooms cooled with ice 

 that you could hang up a wet cloth and it would dry out as it 

 would out of doors. It w^as so dry you could go in there and 

 strike a match on the wall. There is no trouble getting rid 

 of the moisture where we cool with ice, if it is properly con- 

 structed. Have you had any trouble, Mr. Hopkins, with the 

 moisture in your room ? 



Mr. Hopkins : No, I have not. I have always found that 

 the moisture on the tubs of butter or anything else would 

 gather on the iron tank and form ice; it would be in clear crys- 

 tals of ice; it forms on the braces that run across the top of 

 the brine tank. 



The Chairman: Do you think that your atmosphere is as 

 dry as it would be in a perfectly conducted room that was 

 cooled by ice? 



Mr. Hopkins : I think it is, drA^er. 



Mr. Perriam: The excess of moisture in a refrigerated 

 room is shown by the snow that collects upon the cold surface; 

 that is a well-knowm principle, so that the more snow or ice 

 that collects upon a cold surface, the more moisture is taken 

 up. That is one way of taking up moisture. 



Mr. Dexter: There is never any trouble about moisture 

 in a room properly contructed. 



Mr. Wentworth: There is no question in my mind that 

 among the ice boxes in Hlinois and Iowa there is not one in 

 twenty-five, properly contructed, so that the surface of your 

 tubs will be dry; for that reason I believe that for the average
