HANDLING WHEAT FKOM FIELD TO MILL. 



the agricultural college, Fargo, N, Dak. The loss in milling on this 

 sample so far exceeded the average loss of 2.12 per cent on like 

 samples of hard spring wheat milled at Fargo that some explanation 

 is necessary. This excessive loss was probably due to the high mois- 

 ture content of the wheat and also to the fact that the mill had not 

 been used for some days, and although some wheat was ground in 

 order to '' fill the mill " and products were received from all the 

 spouts before sample No. 398 was started, still the milling loss was 

 far in excess of the average for hard spring wheat. 



A second sample of the shock-thrashed wheat (No. 398 A) was 

 milled on September 17, after the wheat had remained in the bin 

 eighteen days. The wheat milled tough, and it Avas very difficult to 

 clean off the bran. The wheat appeared to be going through a sort 

 of sweat, and it felt more tough and clammy than when first placed 

 in the bin. 



After the lot of shock-thrashed wheat (No. 398) had been stored in 

 the elevator bin for sixty days, 50 bushels of the stack-thrashed lot 

 (No. 460) were received at the mill. The stack-thrashed wheat con- 

 tained 13.2 per cent of moisture and tested 59 pounds per measured 

 bushel, as against 14.8 per cent of moisture and 55.5 pounds per bushel 

 in the shock-thrashed wheat at the time of thrashing. 



On October 26 a third sample of the shock-thrashed wheat (No. 

 398 B) Avas milled, and a sample of the stack-thrashed wheat (lot 

 No. 460) was likewise milled on the same day. By comparing the 

 data in Table I it will be noted that in the milling of the stack- 

 thrashed wheat (sample No. 460) there was less loss in cleaning the 

 wheat and less loss in milling (except sample No. 398 B) and that 

 there was less bran, more " low grade " and shorts, and more straight 

 flour produced than was the case with the other three samples milled. 



No change in the temperature of the shock-thrashed wheat had 

 taken place during storage except the slight variation apparently due 

 to changes in the outside air temperature.
