On the Hessian Fly, 137 



acres can be brushed over in one day, and can be ma- 

 naged by any active, trusty boy, of twelve or fifteen 

 years old, without making any vacancies, as one of the 

 wheels will run along the furrow during the operation. 



The plan is new to me and no doubt the machine will 

 admit of great improvement. 



1 thought it my duty as a member of the Society to 

 lay the implement before them at the present meeting, 

 as the time is at hand for putting it into immediate ope 

 ration. 



Yours, &c. 



John Lintgx.
