CHAP. VII.] THE SECOND DAT. 409 



1. We have besides for this month, a little dun called a 

 Whirling-Dun, 1 though it is not the whirling-dun indeed, 

 which is one of the best flies we have ; and for this the 

 dubbing must be of the bottom fur of a squirrel's tail, and 

 the wing of the gray.feather of a drake. 



2. Aso a Bright 'Brown ; the dubbing either of the brown 

 of a spaniel, or that of a cow's flank, with a gray wing. 



3. Also a Whitish Dun, made of the roots of camel's hair, 

 and the wings of the gray feather of a mallard. 



4. There is also for this month, a fly, called the Thorn- 

 tree fly ; the dubbing an absolute black, mixed with eight or 

 ten hairs of Isabella-coloured 2 mohair, the body as little as 

 can be made, and the wings of a bright mallard's feather : 

 an admirable fly, and in great repute amongst us for a killer. 



5. There is, besides this, another Blue Dun, 3 the dubbing 



of which it is made being 

 thus to be got. Take a 

 small-tooth comb, and 

 with it comb the neck of

1 Variation. GREAT WHIRLING DUN. Dub with, fox-cub or squirrel's 

 fur, well mixed with about a sixth part of the finest hog's- wool : warp 

 with pale-orange wings, very large, taken from the quill-feather of a ruddy 

 hen : the head to be fastened with ash-colour silk ; a red cock's hackle, at 

 full length, may be wrapped under the \vings, and, a turn or two lower, 

 towards the tail. This is a killing fly, and is to be seen rising out of the 

 sedges in most trout rivers after sunset till midnight. It is found most of 

 the warm months ; but kills chiefly in a blustering warm evening, from 

 the middle of May to the end of July. H. 



2 A species of ivhitish-yelloio, or buff-colour sometvhat soiled. The name 

 of this tint is said to have originated in the following circumstance. The 

 Archduke Albert, who had married the Infanta Isabella, daughter of 

 Philip II. king of Spain, with whom he had the Low Countries in dowry, 

 in the year 1602, having determined to lay siege to Ostend, then in the 

 possession of the Protestants, the princess, who attended him in his 

 expedition, made a vow that until it was captured she would never change 

 her garments. Contrary to expectation, it was three years before the city 

 was reduced ; by which time her Highnesses linen had acquired the hue 

 above-mentioned. H.

 tail, and a very little blue violet worsted : warp with pale yellow silk ;
