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, taiUngs, and low grade stock 

 was 0.367 per cent for mill No. 1; 0.358 per cent for miU No. 2; and 

 0.452 per cent for miU 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

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 gTiadhig was greater than before. It is 

 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
