• 



in I put in a factory that was only making from twenty to 

 fifty tubs during the season; that plant cost |625. 



Mr. Wentworth: Did you let it out on contract, or did 

 you fix up the box yourself? 



Mr. Hopkins: I built the box when I rebuilt the factory. 

 I just simply used flooring and filled between the studding 

 with mineral wool at that place. 



Mr. Dexter: We understand that with this machine it 

 is not necessary to have ice in the creamery at all? 



Mr. Hopkins : No, sir, it is not. You can use it for 

 cooling the cream or for cooling water to cool the cream with. 



Mr. Carlson: Do yoii use a specially made vat for cool- 

 ing your cream? 



Mr. Hopkins: No, sir; it runs over coils. 



Mr. Carlson: Do you in any way regulate the tempera- 

 ture of your cream? 



Mr. Hopkins: Not when we use this ice machine. 



Mr. Hostetter: Could you freeze ice in your vat if you 

 wanted to? 



Mr. Hopkins: Yes, with the aid of some pans to put 

 in the brine tank, on a small scale. 



The Chairman: You understand the brine is reduced 

 several degrees below the freezing temperature of water and 

 that becomes covered with ice. The vat is made of galvanized 

 iron. 



Mr. Hostetter: Nearly every family wants a little ice in 

 the house and the question is whether a man could not use 

 the same pans in there and make his own ice. 



The Chairman: He can do that if he wishes. 



Mr. Hopkins: The brine in our tank stands about 16 to 18 

 degrees and it probably has three or four hundred pounds of 

 ice sticking to the tank. 



Mr. Dexter: Do you think your machine is properly con- 

 structed so that there is no danger of leakage, or the escape 

 of ammonia worth considering? Have you had any trouble 

 that way? 



Mr. Hopkins : No. We had some trouble at first with the 

 packing we were using, but we soon remedied that. 



Mr. Carlson: If you should accidentally have any trou- 

 ble what would be the effect on your cream?
