CHALK-STREAM FISHING WITH DRY FLY. 349 
the hotter the sun the better does this fly succeed. It is not 
generally known that when trout are ‘ smutting’—i.e. feeding on 
that tiny black midge which baffles all imitation—they will 
often take a small red tag ravenously. On one of the hottest 
days in August 1884, fishing at midday, I hooked eight large 
trout with the red tag, and this on a piece of water which it 
was usually considered hopeless to fish before dusk. As for 
grayling, when they are lying basking on the gravel in about 
two feet of water, the red tag will almost always bring them up. 
I have had splendid sport with it on many occasions. This is 
the dressing : 
Body: Peacock herl, short and fat, with a tiny red tag of floss 
silk, wool, or scarlet ibis feather. Floss silk looks very 
well when it is dry, but it shrinks up when wet, and 
often loses its colour ; I have always found wool much 
more killing. 
At the shoulder should be wound a dark, rich, red 
hackle. 
Hook, 0, 00, or 000. 
XVII THE JENNY SPINNER, 
(Fig. xvii. p. 344.) 
This is the transformation of the iron-blue dun, and is one 
of the most beautiful and delicate flies to be found by riverside. 
It is often seen dancing up and down in thousands after a hot 
day, and the fact that it is by no means uncommon on rivers 
where the iron blue is scarce, leads me to think that some other 
summer duns (possibly the little sky blue) turn to this delicate 
transparent spinner. It is impossible to see it on the water, 
and at best it is a most difficult fly to imitate. For these two 
reasons sport with it is somewhat uncertain. 
It should be dressed with a detached body of white 
_ horsehair tipped with a couple of turns of mulberry silk 
and white whisks, Tie the body to a oo or 000 hook 
with mulberry coloured silk to show the head and thorax
