before the operation took place ; for, on examining it 

 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, fimple as the procefs is, I flatter myfelf, it 

 bids fair to preferve fine crops of corn from deftrue- 

 tion, as the fmall infects are the crops greater! ene-

 or ten eggs of an oblong fhape on my thumb, only 

 while carrying by the wing acrofs three or four ridges, 

 as appeared on viewing it with a pocket microfcope. 



4th. Crops of turnips are frequently deftroyed, . 

 when young, by being bitten by fome infects, either 

 flies or fleas; this I flatter myfelf maybe effectual- 

 ly prevented, by having an elder bum fpread fo as 

 to cover about the breadth of a ridge, and drawn \ 

 once forward and backward by a man over the 

 young turnips, I am confirmed in this idea, by 

 having ftruck an elder bum over a bed of young 

 collyflower plants, which had begun to be bitten, 

 and would otherwife* have been deftroyed by thofe 

 infects ; but after that operation, it remained un- 

 touched. 



In fupport of my opinion, I beg leave to men- 

 tion the following fad from very credible information, 

 that about eight or nine years ago this county was fo 

 infefted with cock chaffers, or oak webs, that in many 

 parifhes they eat every green thing, but -elder; nor 

 left a green leaf untouched befides elder bufhes, 

 which alone remained green and unhurt, amid the 

 general devaflation of fo voracious a multitude. On
