STONE FLIES— PERU DM. 47 



The Yellow Sally recalls still wilder scenes amongst 

 the moors ; climbs past waterfalls ; the stalking of the 

 spotted beauties in the pools ; and the trudge home 

 again in the dusk, wet, tired, and hungry, but withal 

 happy and contented — the cry of the plovers and curlews 

 and a host of other sights and sounds far from the 

 madding crowd — I have been and still would go ! 



The Willow Fly recalls lower reaches mostly, warmer 

 weather, and balmy Autumn afternoons with a blue 

 haze and a yellow sun, and fine mixed baskets of trout 

 and grayling. 



All the PerlidcB are old friends, however, and it 

 seems invidious to mention one without saying some- 

 thing pretty of each in turn. 



These flies look very important on the wing, but when 

 at rest, comparatively small, owing to the close way in 

 which the wings are folded up. 



Theakston calls them " Browns " owing to the brown 

 colour which appears when they are viewed against 

 the light, principally due to the reddish brown tinge of 

 the nervures of the wings. 



Hackled imitations which are frequently highly 

 successful are shown, but these must be dressed on very 

 small hooks (for the upper waters especially).
