EPHEMERA. 133 
April does not come on elsewhere till June, or in 
a third locality is over by the middle of March. 
On the Greenwash, for instance, at the opening of 
the season the successful flies used are the duns, 
dressed from light and dark snipe, with sometimes 
starling and dotterel. The famous “ March- 
browns” float down-stream later than their name 
would imply, and one of the best of all lures, the 
May-fly (represented in the north by the stone- 
fly), does not make its appearance till June, or 
sometimes July. April and May, if soft and 
bright, usually present the greatest number of 
flies, these sometimes seeming to cover the surface 
of the stream. And here among the grasses and 
water-avens you might say of a dozen species as 
has been said of one: 
You find her out on every stalk, 
Whene’er you take a river walk, 
When swifts at eve begin to hawk. 
There are duns of every form and colour— 
gnats and willow-flies, and creepers among the 
pebbles; and insects, insects everywhere. You can 
put aside your rod, and lie down among the lush 
summer grass, and examine them at your leisure. 
The mechanism of each is wonderful, and all are 
beautiful. But by carefully observing, you are 
instantly aroused—as what angler would not be ?—
