laft week, I found the corn which had been ftruck 
pretty free of the yellows, very much more fo than 
what was not ftruck. I have, therefore, no doubt but 
that, had the operation been performed fooner, the corn 
would have remained totally clear and untouched. 
If fo, Ample as the procefs is, I flatter myfelf, it 
bids fair to preferve fine crops of corn from deftruc-

left a green leaf untouched befides elder bufhes, 
which alone remained green and unhurt, amid the 
general devaluation of lo voracious a multitude. On
