INTERPRETATION OF THE RESULTS. 



The first eleven numbers represent milk collected from Amherst 

 milkmen. 



Number one : Samples were collected during winter, spring and 

 summer months. They were remarkedly free from bacteria, did not 

 have any objectionable taste or odor, and in no case contained a 

 large number of liquefiers. This milk was produced under the 

 most cleanly conditions of any found in this vicinity. The cows 

 were well brushed and bedded, and the stable fairly cleaned and 

 passably ventilated. Not much more could be expected from one 

 retailing milk at six cents a quart. 



Number two : The several samples, with one exception, con- 

 tained comparatively few bacteria and were evidently fresh. Most 

 of them had a bad odor, being indicative of poor handling. The 

 stable and cows were rather dirty, and the former poorly ventilated. 



Number three : Comparatively small number of total bacteria and 

 few liquefiers, indicating new milk. Colonies from sample collected 

 July II, on which total count only was made, gave a rank odor of 

 manure. Sanitary conditions of stable not satisfactory. 



Number four : An excessive number of bacteria in nearly all 

 samples collected. In most cases the percentage of lactic acid bac- 

 teria present does not indicate old milk. In many cases the rela- 

 tive number of liquefiers (especially slow liquefiers) was excessive, 

 which is indicative of a dirty milk. Many samples had a barny 

 odor. Cows were dirty, lacked bedding and fresh air. Improve- 

 ment urgently needed. 



Number five : Three out of five samples contained an excessive 

 number of bacteria for country milk. Milk had a bad odor; stable 

 not clean, cows very dirty, and milk room in bad condition. 



Number seven : Three out of four samples contained few bacteria, 

 an indication of fresh milk, well cared for. Sample collected July 

 1 1 was old, or kept at too high a temperature ; it contained too 

 many liquefiers. Earn fairly clean and ventilated by air shafts. 

 Cows bedded and fairly clean. Water supply in danger of pollution. 



Number eight : Excessive bacteria and dirty milk with old rank 

 smell. Stable dark and filthy ; cows dirty. 



Number nine : Excessive total number of bacteria ; condition of 

 stable, milk room and cows very bad.
