number increasing in one case, in the other diminish- 

 5no\ Whatever be the temperature of the atmosphere, 

 wliether it be cold or hot, these flies invariably appear 

 at the same hour in the evening, that is, between a 

 quarter and lialf-past eight: towards nine they begin 

 to fill the air; in tlie following half-hour they are in the 

 greatest numbers ; and at ten there are scarcely any to 

 l>e seen. So that in less than two hours this infinite host 

 of flies emerge from their parent stream, fill the air, 

 perform their appointed work, and vanisli. A very 

 large proportion of them falls liito the river, when the 

 fish have their grand festival and the fisherraen a good 

 harvest^. 



Under this head I may observe how- much the patient 

 angler is indebted to insects for some of his choicest 

 baits, for the best opportunities of showing his skill, and 

 for the most gratifying part of his diversion. The case- 

 worm and several other larvee are the best standing bait 

 for many fish. The larva of the Ephemera, there called 

 bait and bank-bait^, is much used in some parts of FIol- 

 land. The case-worms, and grubs (I suppose of Sie?) 

 from the tallow-chandlers are in request with us for 

 roach and dace ; and I am told by an acute observer of 

 these tilings, the Rev. R. Slicppard, that the larger 

 Scarabaei andMelolonths are good baits for caub^. B^it
