Milking Methods. 



"The milking has been done throughout the season with three 

 L.K.G. milking machines. Before the machines were applied 

 the milk of each cow was carefully examined by the super- 

 visor, a small quantity being drawn from each teat for the 

 purpose, as a check against milk being used from injured 

 udders, and also as a means of detecting the symptoms of any 

 of the various diseases of the udder affecting the milk supply. 

 'These precautions were taken daily throughout the season. 

 The foremilk, about four streams from each teat, was then 

 taken, and the teats and udders were carefully washed with 

 warm water, clean water being used for each pair of cows. The 

 machines were then applied, and after removal the cows were 

 stripped out by hand into special buckets with cotton-wool 

 strainers fitted into the mouth. The milk, after being weighed, 

 was passed through a cleansing centrifuge, and thence over the 

 refrigerator, and the temperature reduced to 40 deg. Fahr., and 

 immediately bottled, sealed and dated, placed in crates, packed 

 in ice, and delivered to the distributing agents within four 

 hours after being milked, every precaution being taken during 

 the whole process to ensure cleanliness. All utensils, milk 

 bottles, and everything coming in contact with the milk was 

 sterilised twice daily. All teat cups and rubberware in connec- 

 tion with the milking machines were boiled twice daily in soda 

 water 10 per cent, strength, and left in the sterile water between 

 milkings, and immediately before being used were blown out with 

 dry steam. The machines were also sterilised at intervals 

 during the milking operations by being placed in boiling water 

 and soda alter each machine had milked a pair of cows, oppor- 

 tunity being taken for this work in the interval during which 

 the bails were hosed down and a fresh section of the herd 

 brought in. The process of sterilising the milking machines 

 received special attention by the supervisor through the season. 

 All the employees at the dairy were provided with a clean'
