The second layer is the skim-milk, while the cream,being the lightest, is forced to the center of the bowl and formsthe third portion mentioned. There is no distinct line ofdemarcation between the layers of skimmed milk and overlap each other and form a sort of zone, rather thana sharp separation. The richest cream is nearest the centerof the bowl, and gets thinner toward the outer portion of thebowl; consequently, by turning the outlet for the cream, orcream-screw, nearer the center of the bowl, the cream is increased i;«i lilllllli; M Ah I Nil. ill IiclmcMfi. riiiniiip; il MAVJiy lioin llic «(ii((
