water by having sufficient ammonia coils in a tank and then circulat- 

 ing the water over them with a pump. 



Or, if intense cooling is desired, have the coolers made of tinned 

 copper and circulate cold brine in them. The latter, of course, is im- 

 practical to use in tin coolers. 



I give fair warning that a good refrigerating plant cannot be 

 bought for a song, and that a poor one is nothing but vanity and 

 vexation. 



If sufficient power is present (and it requires it just at a time 

 when other machinery is running), then a good enough plant can be 

 put in a milk depot for from $1.000 to $1,500, and in a creamery 

 where cream only is pasteurized for $800 to $1,000. 



In making inquiries from some manufacturers I have been 

 amused at their refusal to give a description of their apparatus. Thus 

 the Star Cooler Mfg. Co. anounces in mysterious terms a new device 

 but refuses to describe it, and I understand that Messrs. D. H. Bur- 

 rell contemplate putting on the market, not only pasteurizers of "ap- 

 proved style and effect" but also a new special apparatus for the 

 practice of Mr. J. D. Frederiksen's process for treating tainted milk. 

 Mr. F. has been working on a method for eradicating bad flavors, es- 

 pecially the garlic flavor so common in Eastern Pennsylvania, Mary- 

 land and adjoining territory, for the last few years, and has succeeded 

 in devising a plan which on account of simplicity and efficiency is 

 likely to be generally introduced wherever milk is tainted with the 

 flavor of garlic, ragweed or the like. As soon as the apparatus is 

 perfected it will be offered to the dairymen, and it seems that relief 

 is at last in store for the sections of the country where these pests 

 have heretofore prevented successful dairying though otherwise they 

 are eminently well adapted to this industry."
