12 SOUTH COUNTRY TROUT STREAMS 



another chalk stream insect — its imago being the 

 oddly named sherry spinner — may be regarded in 

 the same light, as may the little yellow May dun, 

 or, as it is sometimes rather well named, little 

 May-fly dun. I have seen the latter on various 

 streams in north and south, but only once or 

 twice in anything like abundance. Last season I 

 saw a regular hatch of this beautiful insect, which 

 is considerably larger than the ordinary yellow 

 dun, and found a good Test trout rising at every 

 one which came into a sort of little bower he was 

 inhabiting. It was a cold dull evening just before 

 the height of the May-fly season. Upon compar- 

 ing notes with Mr. William Senior I found that 

 he too had noticed a hatch of the same fly that 

 day on the Itchen. 



To turn to the second group of flies. The 

 March brown is a regular Devon insect, and a 

 more agreeable sight than a rise of the troutlets 

 of this delightful county at a large hatch of the 

 insect it would surely be difficult to imagine. It 

 would scarcely be too much to say that on every 

 length of every stream in Devonshire, if not of 

 Cornwall and Somerset too, it is a standard fly 

 throughout the earlier part of the season, possibly 

 only surpassed in popularity by the blue upright. 

 The artificial, or rather series of artificials known 

 as the blue upright is, unlike the March brown, 

 very little in demand among south country anglers 

 outside the counties of Devon, Somerset, and 

 Cornwall, though it is occasionally used on " dry 

 fly waters " in Kent and Gloucestershire. There 

 is no natural insect known as the blue upright, 

 and there exists some difference of opinion as
