GENERAL CONCLUSIONS ON STRAIGHT FLOURS. 
1. The commercial grades of so-called straight flours ranged from 
90 to 100 per cent. 
2. The average total offal count obtained on all commercial straight 
flours examined was 111. 
3. Straight flours showed a decided variation in the total offal 
count obtained on different samples from various mills. 
CLEAR FLOURS. 
Clear flour, so-called, is often considered among millers as being a 
mixture of odds and ends of the milling stocks. Low grades of mid- 
dlings and break flours often pass into it, although frequently it con- 
tains the purest quality of middlings stock from the tail of the mill. 
Clear flours which were said to have been milled from hard, soft, and 
blended wheats, respectively, were examined. 
CLEAR FLOURS MILLED FROM HARD WHEATS. 
Thirty-one clear flours stated to have been milled from hard wheats 
were examined. Their percentages ranged from 6 to 52. Table 28 
shows the counts thus obtained.
