1 The wheat milled at mill No. 5 contained about 10 per cent of durum wheat. 
2 No sample obtained. 
The lowest moisture content for tempered wheat recorded here is 
shown to be 13.4 per cent and the highest 16.7 per cent. The former 
appeared in the case of mill No. 5 and the latter in the case of mill 
No. 1. The average moisture content for the five mills ranged from 
14.14 per cent for mill No. 5 to 16.26 for mill No. 1. 
The average inerease in moisture content resulting from tempering 
for the period indicated is shown to have been 2.51 per cent for mill 
No. 1; 2.01 per cent for mill No. 2; 1.08 per cent for mill No. 3; 
0.96 per cent for mill No. 4; and 0.95 per cent for mill No. 5. From 
these results it appears that a diversity of opinion existed among the 
millers of these mills as to the amount of moisture hard red winter 
wheat should contain in order to be properly tempered. 
MOISTURE CONTENT OF WHEAT AND VARIOUS STREAMS OF MILL 
STOCK. 
Table II shows the moisture content of the different streams of mill 
stock and the yield of the various commercial products of three large 
mills. The arranging of the data in this table was difficult because 
of the dissimilarity of the processes used at the three mills. The 
system of separating and grading the stock for subsequent reduction 
at certain steps was not carried out to an equal extent for all the 
mills; consequently, certain streams of stock found in one mill were 
not found in the others nor were streams of stock bearing the same 
name always of similar character.
