CHAP. XVII. THE COMPLETE ANGLER. 209 



* 



coloured fly it turns to ; but doubtless they are the death 

 of many Trouts : and this is one killing way : 



Take one, or more if need be, of these large yellow 

 cadis: pull off his head, and with it pull out his black 

 gut; put the body, as little bruised as is possible, on a 

 very little hook, armed on with a red hair, which will 

 shew like the cadis-head ; and a very little thin lead, so 

 put upon the shank of the hook that it may sink pre- 



tbey grow to be full as long or longer. This is usually called, by sportsmen, 

 the stone-fly ; in Wales they name it the water-cricket, the size and colour 

 being like that insect." 



As to the cock-spur, Bowlker expressly says, in his Art of Angling, p. 70, 

 that it produces the May-fly, or yellow cadew ; which I have ever understood 

 to be the green-drake. 



That which Walton calls the straw-worm, or ruff-coat, though, by the way, 

 he certainly errs in making these terms synonymous, as will here-after be made 

 to appear, and which is described in Ray's Mcthodus intectorum, p. 12. is, I 

 take it, the roost common of any, and is found in the river Colne, near Uxbridge ; 

 the New River, near London ; the Waodle, which runs through Carshaltou in 

 Surrey; and in most other rivers. As to the straw-worm, 1 am assured, by 

 my friend above-mentioned, that it produces many and various flics ; namely, 

 that which is called, about London, the withy-fly, ash-coloured duns of several 

 shapes and dimensions, as also light and dark browns, all of them affording great 

 diversion in Northern streams. 



It now remains to speak of the ntff-coat, which seems to answer so nearly 

 to the description which Walton has given of the cock-spur, viz. " that the caw 

 or house in which it dwells is made of small husks, and gravel and slime, most 

 curiously;" that there is no accounting for his making the term synonymous 

 with that of the straw-worm, which it does not in the least resemble : and yet, 

 that the ruff coat and the cockspur produce different flies, notwithstanding their 

 seeming resemblance, must be taken for granted, unless we will reject Bowlker's 

 authority, when he says the cock-spur produces the May-fly or yellow cadew, 

 which I own I see no reason to do. 



But that I may not mislead the reader, I must inform him, that I take the 

 ruff-coat to be a species of cadis inclosed in a husk about an inch long, sur- 

 rounded by bits of stone, flints, bits of tile, &c. very near equal in their sixes, 

 and most curiously compacted together, like mosaic. 



In the month of May, 1759, I took one of the insects last above described, 

 which had been found in the river Wandle, in Surrey, and put it into a small 

 box with sand at the bottom; and welted it five or six times a day, for five days; 

 at the end whereof, to my great amazement, it produced a lovely large fly, nearly 

 of the shape of, but less than a common white butterfly, with two pair of cloak- 

 wings, and of a light cinnamon colour. This fly, upon inquiry, I find is called, 

 in the North, the large light brown ; in Ireland, and some other places, it has 

 the name of the flame-coloured brown. And the method of 

 making it is given in the Additional List of Flies, under Sep- Appendix, 

 tember : where, from its smell, the reader will find it called No. 2. 



the large foetid light brown. 



And there are many other kinds of these wonderful creatures; as may be s*>en 

 in Mons. de Reaumur's Mimoirts pour tervir a I'Histoirt dea Intcctu, Tome 

 III. See also the APPENDIX, No. 1.
