tlic produce was ftill larger. After fowing, m/ 

 fervant told me, that if I did not fend a perfon to 

 frighten the birds, the wheat would be half carried 

 away; however, I let it alone, to fee the efFcd of 

 the foot. Pheafants and partridges had fcraped the 

 ground very much. I particularly marked the fpots, 

 and at harveft, found the corn thicker there than in 

 other places. This convinces me, that the birds 

 could not find any corn fuited to their palates, 

 the foot having rendered it very bitter -, and I had 

 a good crop for fo light a foil. 



2dly, The crops of young turnips are frequently 

 deftroyed by the black flea [fly] notwithftanding 

 many things have been tried to preferve them 3 all 

 of which I am informed have failed. 



On this fubjed I will ofitr a few thoughts:— 

 The fenfe of fmelling in the black flea [fly] and 

 in all other infeds, is exquifitcly acute; without 

 it they know not one plant from another, as their 

 fphere of vifion is probably confined to a very few 

 inches. It is by this fenfe that they are guided 

 to their proper food. The only thing neceflTary 

 then is, to overpower the fweet fmell they are 

 attradted with, by one that is ftrong, foetid, and 

 difagreeable.
