The last three machines were of the old standard hollow-bow 

 type. 



TABLE IX.— SHARPLES RUSSIAN. 



Rated Capacity, Standard, 1,100 Pounds; Imperial, 2,000 Pounds 



Per Hour. 



In Table IX are shown the results obtained in five factories 

 using either the Standard or Imperial Russian machines. It will 

 be noticed, in factory 'No. 2 the operator crowded the capacity of 

 both of his machines much above that rated by the manufacturer^ 

 This is, undoubtedly, the cause of the very large amount of fat in 

 the skimmed milk from the machines in that factory. In factory 

 No. 5 the capacity was also crowded ; but, in this instance, the skim 

 milk showed a very low percentage of fat. 



In regard to factory No. 18, the only factory using the Imperial 

 Russian machine, it was found in the first trial that the percentage 

 of fat in the skim milk was quite large, and at the same time that 

 the capacity was rather small. Upon the morning when the test 

 was made the operator had considerable difhculty in maintaining a 

 uniform pressure on his boiler, and the speed of the machine was 

 quite variable. At the solicitation of the operator, a second visit 

 was made to the factory and the machine tested again when the 

 circumstances were more favorable, with the result that a somewhat 

 lower percentage of fat was found in the skim milk.
