The Curator stated, that he had in the course of the sea- 
son, much conversation with farmers and others on the 
Essex side of the river, and who informed him that since

they had found their land considerably improved ; which 
they attributed to the fact of the prevailing winds blowing 
the smoke, and depositing the soot on that side of the river. 
This subject was fully discussed.
