The COW-DUNG FLY. 

 Appears early in March, but is fel- 

 dom ufed with fuccefe until the latter 

 end of the month ; it will raife fifh in 

 cold, windy afternoons, until the be- 

 ginning of May. Is -a ("mall fly, of a 

 dirty orange color, the bodv of which 

 is fhort and thick, and made of orange 

 color mohair, the wings, which lie flat 

 on its back, of the feather of a .par- 

 tridge's wing, when that is not eaftly 

 procured, a fmall ginger hackle is a 

 good fubftitute. 



This fly is net peculiar to the water, 

 neither do I believe it is bred there ; 

 being an infeft incapable of fuftaining 

 a long flight, the numbers that are 

 beat down by the wind in attempting 

 t-j crofs the ftreams, is probably the 

 principal incentive to the t routs' fond- 

 ncfs for it : f warms of them are fre- 

 quently obferved in paflure lands about 

 the ordure of that animal from whence its 

 name is derived,
