starling's wing feathers. The blue dun comes on in 

 the middle of the day in this month, and is imitated by 

 dun hackles for wings and legs, and an olive dubbing 

 for body. In mild weather, in morning and evening 

 in this month, and through April, the green tail, or 

 grannom, comes on in great quantities, and is well 

 imitated by a hen pheasant's wing feather, a gray or 

 red hackle for legs, and a dark peacock's harle, or 

 dark hare's ear fur, for the body. The same kind of 

 fly, of a larger size, with paler wings, kills well in the 

 evening, through May or June. The imitation of a 

 water insect called the spider fly, with a lead coloured 

 body and woodcock's wings, is said to be a killing 

 bait, on this and other rivers, in the end of April 

 and beginning of May ; but I never happened to see 

 it on the water. The dark alder fly, in May and June, 

 is taken greedily by the fish : it is imitated by a dark- 

 shaded pheasant's wing, black hackle for legs, and a 

 peacock's harle, ribbed with red silk, for the body. 

 At this season, and in July, imitations of the black 

 and red palmer worms, which I believe are taken for 

 black or brown, or red beetles or cockchafers, kill 

 well; and, in dark weather, there are usually very 

 light duns on the water. In August, imitations of 

 the house fly and blue bottle, and the red and black 

 ant fly, are taken, and are particularly killing after 

 floods in autumn, when great quantities of the fly are
