174 Bulletin 66. 



In regard to the simplicity of construction and ease of cleaning 

 and keeping in order of the various machines there is no very- 

 great distinction. Some of the. machines have points of superior- 

 ity over the others in these respects, but none are so complex in 

 working parts or so difficult of thorough cleansing as to raise any 

 considerable objection to their use. 



In conclusion it should be borne in mind that these are tests of 

 single machines of the various kinds, that they were run under 

 conditions fully as favorable as are found in ordinarj^ factory work 

 so far as installation and skill of operation were concerned, but 

 under less favorable conditions, if stopping and starting are 

 sources of loss, than in ordinar}^ factory management because only 

 small amounts of milk were separated at one time.
