for milk will produce a curd with gas holes or piu holes, of a 

 loose or spungy texture and bad odor. 



It is believed that to reveal the presence or absence of filth 

 this test can be relied on with as much assurance as can the 

 Babcock test to reveal the fat content of milk. This agency 

 can be employed to educate the patron to a full appreciation of 

 the quality of his milk which he is offering to the creamery, and 

 this can usually be done without giving the patron any offense. 

 The wonder is that this test is not everywhere used in cream- 

 eries and cheese factories, and also to determine the quality of 

 city milk supplies. 



Under the instruction of the present Wisconsin Dairy and 

 Food Commissioner this test has been made use of by our 

 inspectors in Wisconsin's creameries and cheese factories and 

 in determining the quality of milk supplies. Wherever used the 

 results have been most gratifying and instructive. It is not 

 claimed that this test will reveal "the pathogenic qualities of milk, 

 but it is claimed that it reveals the lack of suitable care and the 

 presence of filth. 



Here is a potent agency which should be brought into more 

 general use to determine the quality of milk furnished cream- 

 eries. The inspector, more than any one else, can be instrumental 

 in bringing into general use by buttermakers the valuable test. 



Another good way of convincing a patron that there is 

 filth in his milk, is to catch the last of the milk as it runs from the 

 can, and after allowing the sediment to settle, pour off quietly the 

 larger part of the milk, filling the bottle up with water; after 

 repeating this process which will largely remove the casein the 

 sediment can very readily be filtered out. The effect of showing 

 the patron the amount of solid filth taken from his milk in this 

 way can not be but productive of good and lead to a change in 

 the right direction. 



The alkaline test is also to be recommended -for use at the 

 weigh can; by it the patron can be convinced that milk may be 

 soured and unfit for separation and still not be thick and loppered. 

 Under certain conditions it is advisable that the inspector make
