The variety known as Harmon Wheat, grown upon clay loam based upon the rocks of the 
Salt group, gave water 11'82, after long drying in the water bath. The last had assumed 
a brown color, and appeared partially charred, although it had never been exposed to a 
temperature above 212° Fahr. 
From the preceding observations, and others of the same kind, I am led to believe that 
this grain has always in combination about the same quantity of water, and that soil and 
varieties do not cause it to vary much either way from 12 per centum of water. This 
amount of water, however, although it is comparatively small, has probably a decided 
influence upon its preservation in transportation to foreign countries. The hygrometric 
power of grains and flour has not been determined. The percentage of water may not of 
itself form an obstacle to its keeping; and if it is not in a situation to imbibe more, it may 
perhaps remain for years in a sound state.
