I have seen some ovens (made by Simonds, Tyrrell & Co., of 

 Chicago), with double walls, which seem to me an improvement, 

 though I presume more expensive. These are made to heat directly 

 with a fireplace in the oven and any desired dry temperature may 

 be obtained. They can also be made for heating with direct steam. 



Mr. H. B. Gurler has built a small room lined with wood for this 

 purpose, and claims it to be superior to those made of galvanized 

 iron, a claim which I shall be willing to allow, when I see the room 

 two or three years hence. 



If I were to use wood I should have it built like a round tank. 

 If absolute sterilization is desired this apparatus should be made 

 of a shape and material strong enough to stand considerable pressure. 



Much labor is also 

 saved by the use of a 

 bottle filler, and in se- 

 lecting one it is well to 

 look carefully after the 

 construction. The sim- 

 plest and the one which 

 is easiest to keep clean 

 is the best. I illustrate 

 one in Fig. 64; it is the 

 cheapest I have seen for 

 small dairies. 



On a very small scale, 

 however, I feel inclined 

 to believe that the labor 

 saved is counterbalanced 

 by the extra work of 

 keeping the apparatus 

 clean. 



By referring to Fig. 

 51, Prof. Russel's idea 

 of filling by syphon may 

 be seen. Not having 



Fig. 64. 



any practical experience with either I cannot express any opinion. 



Selling milk in bottles is getting to be quite common, but unless 

 the utmost care is taken, the advantage of this system is but a delu- 

 sion and a snare.
