Having latel •• got into my possession a piece, dire«S^ 

 Sng how we may toially destroy the Hessian Fly, whicb 

 so often affects our crops of wheat, I feel anxious t® 

 let others reap the benefit that may arise from the same, 

 therefore wish you (if you think proper) to give it a 

 place in your Museum. It was inclosed in a letter di- 

 rected to a gentleman in this place from a Mr. Clark 

 living beyond the city of New-York, where, he says, 

 experiments had been made and |)roved eifcctual. The 



piere came in prifit, and r^ads thus :— -" In ordee 



to - prove the existence of the Hessian Fly in wheat^. 

 «iake a magnifying glass, and examine the grains, and 

 you will liiid near the sprout, or chit, from one to six 

 or seven small dark coloured specks, or nits, wlitjch it 

 Is supposed come to maturity as soon as the wheat be- 

 gins to grow, and increase with the wheat; and on ex- 

 amining the stulk, by strippiug the leaf after it is well 

 «p, the insects may be discovered concealed by the joints. 

 Tiiey are of a very small, white, round, maggotty ap- 

 |)'_'ai ance ; bat as they advaHce to change to the i\y etate, 

 4hey become much darker, resembling the colour of tiax 

 S(;ed, It is when they are in the maggotty state, they 

 do so much mischief to wheat — as soon as they become 

 <lark, they begin to change to the fly state. It is remark" 

 .able, that iiour madv of wlieat having this nit or egg in it 

 is dark coloured. In order to destroy the insect, with- 

 out iiyuring the wheat for seed, take about one peck of 

 slacked iime — put it to about thirty gallons of boiling 

 water, then stir it well, until it is not quite scalding hot j 

 then put one bushel of wheat into a large sieve or rid-
