MILL STREAMS EMPLOYED IN THE MANUFACTURE OF CERTAIN CLEAR FLOURS. 
Tables 31 and 32 record the results obtained on certain mill 
streams which were employed iu making up clear flours. As in the 
case of the commercial grades already considered; these figures are 
merely submitted to demonstrate the quality of the stocks that might 
be used in such a flour from the standpoint of offal material.
