opinion, that long and new dung is. injurious to grain- 
crops. 
I promised to give you an account of my experi- 
ments in cultivating the common field-peas, some 
twenty years ago at Wyoming, in which they were en- 
tirely free from bugs: but this I must postpone for the 
present. 
Iam, dear sir,

Some Thoughts upon Mildews. 
As the public are now, on all sides, calling upon 
every one to communicate his observations upon any 
thing which relates to agriculture ; perceiving in read- 
ing M. Duhamel’s husbandry, that there are a great 
yariety of opinions, about the nature and cause of mil- 
dews upon grain, even among the most celebrated gen- 
tlemen farmers in Europe; and desirous, if possible, to 
contribute my mite towards any useful discovery; I 
have ventured to shew my opinion, founded on such 
observations as fully satisfy myself; as it appears to 
me perfectly to correspond with facts ; and in a natural 
and easy way to account for every appearance and ef- 
fect of that disorder in grain.
