Bulletin 66. 



The peculiarity of this machine is that the bowl is made of 

 aluminum and is much lighter than other bowls of the same ca- 

 pacity. It delivered the cream in verj^ good condition and at a 

 temperature lower by several degrees than the milk entered, but 

 it was not found possible to get cream of a greater fat content 

 than 1 8 per cent, without materially increasing the percentage of 

 fat in the skim milk. We are informed by the manufacturers 

 that this difficulty has been obviated in the machines now made 

 but we have not yet had an opportunity to make a test. 



* Run as a butter machine. 



This machine worked perfectly satisfactorily as a separator in all 

 respects, except that a ver}- heavy cream could not be obtained 

 without materially cutting down the capacity. In the tables of this 

 machine and the Columbia we have added a column'showing the 

 per cent, of fat in the cream of the different runs. In the case of 

 the other machines this was not thought necessary, because the 

 fat in the cream ran uniformly betw^een 25 per cent, and 30 per 

 cent. 



We have also used the Accumulator as a butter machine. On 

 March i6th the representative of the company made two success- 

 ful runs, turning out butter of good grain and texture with a 

 capacity of 300 pounds of milk per hour and with a clean separa- 

 tion. We have not been able to obtain uniformly so good results
