of it all the while, so that if you go in and look at it it looks 

 like a big cake of ice set up on one side of the room. I have 

 put up a little ice at that creamery just as a safe-guard in 

 case an accident should happen, but I am much pleased with 

 the machine. 



Mr. Wentworth: Does it not give you a dryer ice box? 



The Chairman: I think so; as a rule, if you can get a 

 perfect system and everything right up to its best, you c^m 

 get a dry atmosphere with ice, but if it gets a little out of 

 whack, so it wouldn't work perfectly, then we fail to get that 

 dry atmosphere. 



Mr. Wentworth: May I ask either of you gentlemen if 

 you think that in a creamery which in the summer is making 

 fifty tubs of butter, and in the winter running down to 

 eighteen, that an ice machine would be profitable for the 

 creamery to put in? 



Mr. Hopkins: I should think so; if it is profitable for 

 you to use ice at all. I think it would be a saving. 



Mr. Wentworth : Almost every day of my life such ques- 

 tions are asked of me and I want to be enabled to answer 

 them. I came here on purpose to hear this paper on refrigera- 

 tion, so that when I go back into Iowa and these questions 

 are asked me, I can answer with some intelligence. I have 

 visited two or three plants and everybody seems to be very 

 much pleased. It has always been a question of cost and 

 a question whether the thing has come to a state of perfec- 

 tion such as the average creamery man can handle. Would 

 it be profitable in an average co-operative creamery making 

 from twenty to sixty tubs and run in proper shape? Those 

 are two points I am anxious to get at. Of course the expense 

 is not heavy for ammonia and oil and so on. Do you think 

 fifty dollars a year would cover the entire extra cost of run- 

 ning your plant? 



Mr. Hopkins: I think that fifteen dollars would cover 

 the cost of oil and ammonia. 



Mr. Wentworth: And the extra cost of the coal, you 

 think you could handle the whole business for fifty dollars? 



Mr. Hopkins: Yes; we do not run the machine in an 

 ordinary factory over six months. The first machine I put
