with dirty cows and dirty barns. When the cows were brushed, and 

 bedded, and the barns kept in a passably sanitary condition, the 

 total bacterial content, as a rule, was relatively low. In some cases, 

 milk produced in unsanitary barns and drawn from dirty cows did 

 not contain an excessive total count. This may be explained on the 

 ground that the milker was more than usually careful while milking 

 and that the milk was fresh and had been placed in clean vessels 

 and rapidly cooled. 



4. Out of loi samples examined bacteriologically 50 samples 

 contained more than 50,000 bacteria, 41 samples more than 100,000, 

 13 samples over 500,000, and 9 samples over 1,000,000 to the cubic 

 centimeter. 



5. In only 14 out of 69 cases did the percentage of acid produc- 

 ing organisms comprise more than 50 per cent, of the total bacteria 

 present. In the majority of samples the percentage varied between 

 10 and 35. Such figures would indicate that much of the milk was 

 comparatively fresh when offered for sale. 



6. Thirty-two per cent. (22 samples) of the 69 samples examined 

 contained 10 per cent or more of liquefiers. 



7. Of 84 samples examined 55 or 65.5 per cent, had either an 

 old, strong, barny or very disagreeable smell, only 34.5 per cent, 

 being of normal character. This condition is evidently to be traced 

 to a number of sources such as dirty cows, careless milkers, old 

 milk, and especially to allowing the milk to stand exposed to the 

 atmosphere of the stable for a time after milking. 



8. The milk appeared to be comparatively free from visible dirt 

 particles, although upon standing a slight sediment was noticed in 

 many samples. No effort was made to quantitativ'ely determine the 

 amount. 



g. The large number of total bacteria, the excess of liquefiers, 

 and the objectionable odor in so many samples, as well as the many 

 badly kept stables, previously referred to, make clear that a great 

 deal of the milk offered for general consumption was not produced 

 under satisfactory sanitary conditions. It is believed that the con- 

 ditions prevailing in the area canvassed would be similar in other por- 

 tions of the State.
