all the red tiles off from the top of his house, 

 which is just by the water-side, and covered 

 it with blue ones." So do we change claret

On the whole, we have invariably found 

 that the Black Doctor or the Black Dose, or 

 a fly of similar darkness, is unsurpassed in that 

 twilight between sunset and dawn which we 

 call night in Norway. As a fly-tier 1 natur- 

 ally prefer my own variety, which is as 

 follows : 



TAG. Silver twist, and yellow silk. 



TAIL. A topping, Teal and Chatterer. 



BODY. Two-thirds black silk ; followed by one-third 



scarlet seal's fur. Oval silver tinsel ribs. 

 HACKLE. A natural black hackle up the body; gallina 



at throat. 



WINGS. Two tippets, back to back, veiled with Teal, 

 Gold Pheasant tail, Peacock herl and Mal- 

 lard. A topping over all. 

 HORNS. Blue Macaw. 

 CHEEKS. Light blue Chatterer. 



I omit Jungle Cock in the wings, because I 

 think that in this clear water, unless it be 

 on a very dark night, or in a very big river, 

 it is of doubtful advantage. I attach much 

 importance to the Chatterer cheeks. Except 

 the topping, nothing has such a lifelike gleam
