for thermometer 4, figure 3. The corn in this position did not be- 
come hot and actually showed a lower temperature at the end of the 
voyage than during the middle of the voyage, because of the influence 
of the water temperature. The same order prevailed in the natural 
‘“‘Central”’ corn in the other holds in which it was stowed, although 
the temperature in each relative position varied somewhat im the 
various holds. The
