MILKING BY MACHINERY. 125 



vinoed me that the cow, wten she became ac- 

 quainted with the machine, would accept it as a 

 friend. We made some mistakes accidentally 

 and some were made purposely by men who 

 wished to prove the machine a failure that their 

 predictions might become true. 



Comparison of Results. — ^We had some cows 

 milked by hand to compare the shrinkage in 

 flow with those milked by machine as the cows 

 passed along in their periods of lactation, A 

 few months' work revealed that the machine- 

 milked cows made a smaller percentage shrink- 

 age than did the hand-milked, cows. "We also 

 watched the cows when they freshened after one 

 milking period by the machine and by hand 

 and found a larger percentage of damaged 

 udders among the hand-milked cows. 



The machines attracted visitors to the farm to 

 such an extent that I was compelled to prohibit 

 company in the stables at milking time. I had 

 learned that visitors were a cause of shrinkage 

 in milk flow 'when the cows were milked by 

 hand and believed the result would be the same 

 when the machines were used, but waited for 

 proof of it before putting prohibition into ef- 

 f ^ and was finally compelled to make the order. 



I was at this time producing certified milk 

 and was very anxious to leam the comparative 

 numbers of, bacteria in our hand-drawn milk 

 and machine^drawn milk. I paid $150 for bac-
