On May 25 tliis corn was unloaded, weighed, handled over fiA'e eleva- tors, reweighed, screened, weighed a third time, and returned to the car for further observation. When the corn was returned to the car the "second time (May 25) the temperature v\-as 73° F., approximately the same as the temperature of the air at the time the corn was handled. On June 3, 9 days later, the corn in this car was again hot, the maximum temperature being 112° F., showing that hot corn is not made safe for shipment when cooled sim])ly by handling. Figure 3 shows the changes in' temperature in both the car of undried com and the car of dried damaged corn while on the track [Cir. 43]. Please note that these image
