days during the week, making a total of twenty-five and one- 

 half hours that the compressor was run during the week. 



I can not say just what the cost of operating is as we run 

 the compressor at same time we run separators, churn and 

 other machinery. Have tried running the compressor in the 

 afternoon to see what is cost for fuel; weighed the coal used 

 and found 12^ cents worth of coal would run the compressor 

 an hour, at the same time our water pump was running. Ten 

 to fifteen dollars' worth of ammonia will last a year; there is 

 very little expense for oil; perhaps it will take two gallons a 

 year. 



The advantage of the ice machine over the ice is that you 

 do not have to depend on having cold weather to freeze ice. 

 You save all the work of filling your ice house and you save the 

 work of filling your ice box during the warm months, and T 

 believe you can maintain a more even, dry temperature than 

 you can with ice. 



DISCUSSION- 



Mr. Knight: Have you noticed any difference in the 

 quality of your butter since you commenced using the ice 

 machine? 



Mr. Hopkins : No, sir ; I don't think I have. I have tried 

 to have a pretty good quality before. 



Mr. Judd: What is the cost of one of those plants? 



Mr. Hopkins: It varies, according to the amount of 

 piping and the size of the machine. Ours cost about |700 or 

 1800. 



Mr. Judd: How much would it cost to fix up a room 

 in the way you specified? 



Mr. Hopkins: We took a room we had before, and put 

 about a hundred dollars' worth of material we had in there 

 beyond what we had before. 



Mr. Judd: Does it increase or decrease the work? 



Mr. Hopkins: It certainly decreases the work in the 

 summer time; it takes away all the hard, dirty, nasty work. 

 I think it saves work the vear around.
