1 The wheat milled at mill No. 5 contained about 10 per cent of durum wheat. 

 3 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 increase 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 tliree large 

 mills. The arranging of the data in this table was difficult because 

 of the dissimilarity of the processes used at the tliree 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.
