SHIPMENT AND STORAGE. 



Half of each lot was shipped to Savannah and half to New Orleans, 

 the analyses being made from month to month in the Government 

 laboratories located in these cities. Each of the three cars destined 

 for each city contained two parallel lots — that is to say, two half lots 

 of whole-kernel meal and two of cream meal, representing two de- 

 grees of dryness. Care was taken not to allow the two kinds of meal, 

 or meal of the same kind with extreme moisture content, to come in 

 contact either in the car or the storage warehouse, also to so bury the 

 bags for analysis in the piles that they should be surrounded by bags 

 of the same lot on all sides. The storage warehouse at Savannah was 

 similar to that used in the preceding experiment, while that at New 

 Orleans was a large, modern structure of several stories, dimly lighted 

 but quite well ventilated. 



ANALYSES AND TESTS OF THE STORED MEAL. 



The analyses shown in Table 12 are the most instructive of all those 

 given in this bulletin and show conclusively the superior keeping 

 qualities of degerminated meal. 



' Moisture. — The lots with high moisture, i. e., A, B, and C, regard- 

 less of the kind of meal, lost weight during storage, while the drier 

 lots, D, E, and F, in most instances gained. In cases where the meal 

 heated the loss in weight was not only considerable but noticeably 

 greater than the loss in moisture, indicating that carbon dioxid was 

 given oil in appreciable amount. 



Acidity. — The whole-kernel meal, even when dried to less than 11 

 per cent of moisture, became sufficiently acid to exceed the limit of 

 30 in from four to eight weeks and finally reached from two to over 

 three times that limit. On the other hand, the degerminated meal 

 gained slowly in acidity, the limit being exceeded in sixteen weeks 

 only in lot B stored at New Orleans. The highest acidity that was 

 reached in the degerminated meal of lots C, D, E, and F, which con- 

 tained 15.72 to 11.26 per cent of moisture at the outset, was 30.1 and 

 that only after 28 weeks' storage.
