BULLETIN 839, U. S. DEPARTMENT OF AGRICULTURE. 



The bran particle count varied from 126 to 308, with an average 

 of 218. The hair count ranged from 30 to 167, with an average of 

 86. The total offal count ranged from 158 to 412, with an average 

 of 306. 



CLEAR FLOUKS MILLED PROM BLENDED WHEATS. 



Twelve samples of flour stated to have been milled from blended 

 wheats were examined. The commercial grades ranged from 10 to 

 30 per cent. Table 30 gives the results of the examination.

MILL STREAM8 EMPLOYED IN THE MANUFACTURE OF CERTAIN CLEAR FLOURS. 



Tables 31 and 32 record the results obtained on certain mill 

 streams which were employed in 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.
