The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
The colour of tups testicle wool is caused by urine according to a farmer friend.The wool from a tup is not the quality of the wool taken from sheep so it is of no commercial use.To get the lanolin out of the wool can be a right pain because you cannot rub it or wring it out because it will matt so its a case of gentle agitation whilst it is in the water and soap mix it is then taken out and laid flat to let it dry naturally.
'The essential part of this dubbing is the highly translucent wool from the indispensable part of a Tup, thoroughly washed and cleansed of the natural oil of the animal. This wool would by itself be, like seal’s fur, somewhat intractable and difficult to spin on the tying silk, but an admixture of the pale pinkish and very filmy fur from an English hare’s poll had the effect of rendering it easy to work. There was also in the original pattern an admixture of cream coloured seal’s fur and combings from a lemon yellow spaniel, and the desired dominating colour was obtained by working in a small admixture of red mohair. For the mohair I generally substituted seal’s fur, and I believe Mr. Austin did so himself. When wet the Tup’s wool becomes somehow illuminated throughout by the colour of the seal’s fur or mohair, and the entire effect of the body is extraordinarily filmy and insect-like.
Do you think if they could they'd lie as often and as much as we fly fishers?
