158 MODERN PRACTICAL ANGLER. 
optician, must in every case be taken as the basis. Thus 
in the gold-fly—the prevailing colour of which is intended 
to be a rich golden orange—red, orange, and yellow are 
the three predominant colours—orange (the gold of metal- 
lurgists) in the prismatic arrangement passing into red 
on the one side and yellow on the other. In “the Rain- 
bow” the same model is closely followed, the whole 
of the prismatic colours being combined in the body 
and shoulder hackle in their proper sequence. In No. 3, 
which is a silver-bodied fly, no harmony of colour is 
strictly speaking possible—silver (or white brightened) | 
not being a colour but rather a negation of it. Ina 
more general sense, however, both white and black har- 
monize with all the other colours. 
It will be seen that the “silver” fly is tied on a double 
hook. This is a plan which I first saw practised by Dr. 
Peard, the accomplished author of “ A Year of Liberty,” 
to whom I was also indebted for the original flies on 
which, with the exception of the extra hackle, and some 
modifications of colour, the pattern-flies here given are 
based, The addition of the second hook perceptibly 
influences for good the proportion which losses bear to 
runs. It is also rather an improvement than otherwise 
to the fly, so far as neatness goes, and helps to sink it a 
trifle lower in the water—another advantage, in my 
opinion. The hooks are set at rather less than a right 
angle. 
. The following is the formulary for these flies ——
