whether, or under what conditions, their installation would be 

 financially profitable, data are lacking. Owing to rapid and re- 

 peated changes and improvements in the milkers used in these 

 tests and the substitution of new pails and parts, it has been im- 

 possible to measure the deterioration of the machines or to get 

 any very definite idea as to the cost of maintenance. Until these 

 data can be secured, possibly not for a long period of time, each 

 herd owner will have to decide for himself whether the saving in 

 labor indicated above will justify him in installing machine 

 milkers. 



The Station experience proves that such machines, at least the 

 one used by us, can be readily handled by the better grade of farm 

 laborers, that they can easily be made to produce milk with very 

 satisfactory bacterial counts, that they do not injuriously affect 

 the flow of milk and that they will lessen the amount of human 

 effort necessary to milk cows.
