STORAGE EXPERIMENTS WITH CARLOAD LOTS OF MEAL MILLED MAY 23, 1913. 



DESCRIPTION AND ANALYSES OF THE MEAL AS MILLED. 



This experiment was carried out with carload lots (40 tons) of 

 undried and highly dried meal. The meal was packed in 100-pound 

 cotton sacks. As it was impracticable to mix thoroughly all of the 

 meal of each lot, one ton (20 bags) was taken out for subsequent 

 sampling, turned over on a floor with a shovel until uniform, and 

 rebagged. One of these bags furnished the sample at the end of each 

 period at each of the cities where the meal was stored. In both the 

 cars and storage warehouse these sample bags were kept in the middle 

 of the pile with bags of the same lot on all sides. Analyses of the 

 meal when milled appear in Table 9. 



Table 9. — Composition of carload lots of degerminated, bolted, roller-ground corn meal, as 

 milled with and without drying, May 23, 1913, for use in storage experiments.
