as circumstances at that time, and since, did not appear to 
require that great publicity should be given to this process, I 
contented myself with describing it to you and a few of my 
other friends. Now, however, when I reflect on the large 
quantities of corn which, during the last harvest, have been

importation may be partially frustrated by the destruction of 
a large portion of grain, and the consequent increase in the 
price of the remainder, I think it incumbent on me, by 
addressing this Letter to you, to lose no time in publishing a 
process, by which corn, however musty, may be completely
