 passes back and forth over 

 the butter, which is occa- 

 sionally turned Over. The 

 butter in the trough is 

 shown at a, and the fluted 

 roller at b.

 In Fig. 898, A, A, are 

 guide-scrapers for conducting the butter under the roller ; B, 

 scraper for freeing the roller from the butter ; C, C, groove for con- 

 veying the buttermilk to the pail.'
