in May-fly such as the Test and the Kennet, the 

 one running by Stockbridge, the other by Hungerford. 

 But in the Wandle at Carshalton and Beddington, 

 the May-fly is not found ; and the little blues are the 

 constant, and when well imitated, killing flies on this 

 water ; to which may be joined a dark alder-fly, and 

 a red evening fly. In the Avon, at Eingwood and 

 Fordingbridge, the May-fly is likewise a killing fly ; 

 but as this is a grayling river, the other flies, 

 particularly the grannam and blue and brown, are 

 good in spring, and the alder-fly or pale blue later, 

 and the blue dun in September and October, and 

 even November. In the streams in the mountainous 

 parts of Britain, the spring and autumnal flies are by 

 far the most killing. The Usk was formerly a very 

 productive trout stream, and the fish being well fed 

 by the worms washed down by the winter floods 

 were often in good season, cutting red in March, 

 and the beginning of April; and at this season the 

 blues and browns, particularly when the water was a 

 little stained after a small flood, afforded the angler 

 good sport. In Herefordshire and Derbyshire, where 

 trout and grayling are often found together, the same 

 periods are generally best for angling; but in the 

 Dove, Lathkill, and Wye, with the natural May-fly, 

 many fish may be taken; and in old times, in 

 peculiarly windy days, or higk and troubled water,
