MOISTURE IN WHEAT AND MILL PRODUCTS. 9 
due to the higher moisture content of the break streams of mill No. 1. 
On the other hand, the average decrease for the reductions, or those 
grinding operations of sizings, middlings, tailings, and low grade stock 
was 0.367 per cent for mill No. 1; 0.358 per cent for mill No. 2; and 
0.452 per cent for mill No. 3; or, in other words, was least for mill 
No. 1 and greatest for mill No. 3. These differences among the mills 
in the average decrease of moisture content resulting from grinding

Fic, 2—Diagram showing differences in the moisture content of flour 
resulting from the various grinding operations. 
was probably due in part to variations in methods of milling and in 
atmospheric conditions at the time of grinding. 
Four instances are shown in which the percentage of moisture con- 
tained in the roll stream after grinding was greater than before. Itis 
possible that in these instances the samples from which the determi- 
nations were made were not representative of the streams sampled, 
and, therefore, the results obtained do not represent actual conditions. 
The fact that three of the four instances appeared in connection with
