DEAR SIR, 



JL HE very polite and obliging attention fo frequently fhown by you 

 to my trifles in Natural Hiftory, encourages me to trouble you with 

 this letter, to be laid, if you think proper, before the Linnean So- 

 ciety } and fliould they difcover in it any thing that at all tends to 

 improve the fcience, or that may be in any other refpeft ufefnl, 

 I {hall feel myfelf highly gratified. 



Having ordered a field of clover, confiding of about eight acres, 

 to be faved for feed, my fervant, on the 9th of Auguft laft, afked me 

 whether I chofe to fave the whole field for that purpofe, faying that 

 he had examined feveral of the heads, and found the maggot in 

 them. On this information I was induced to order only a part of 

 the field to be faved for feed, and the reft to be mowed for hay. 

 Soon after, I went myfelf to examine the ftate of the clover, and 

 found in many of the heads feveral fmall white maggots or larvje, in- 

 variably placed on the outfide of the bafe beneath the individual 

 calyx of each floret, eating through the bottom, and thereby 

 deftroying the germen or rudiment of the future feed. Each of 

 thefe larvae appeared to be exaftly fimilar in fhape and colour (only 

 much fmaller) to the nut maggot, having a white body, black head^ 



and.
