an inch and a half long in the fibre can easily 
be obtained by feather-dyers and tackle-makers, and 
up to this size anglers using the flies recommended 
should insist upon the proper proportion being main-

The principal wing-feathers in all these flies are the 
black and white neck hackles of the jungle cock, and 
the next in importance feathers from the golden pheasant 
known as “toppings’—perhaps the two feathers which 
experience has proved to be on the whole most killing 
for Salmon in the greatest variety of combinations. If
