of the stream—the rough cases of the duns sheltering under 
or attached to the stones—the browns and drakes scamper- 
ing about for cover again. They will hatch their flies in 
water pots if not disturbed, and the water kept constantly 
fresh. They draw to the edges of the waters, towards their 
maturity, and as the season advances, and in summer, they 
swarm with them, when the waters run quick with life, as 
the poet sings :— 
“See through this air, this ocean, and this earth, 
All matter quick, and bursting into birth.’”’ 
In addition to these three classes of creepers vast varieties 
of the spinners, beetles, gnats, midges, etc., are perpetually 
progressing and pouring their winged progeny on the 
waters daily throughout the season, making ample store 
and choice for the fish, and a task for the flyfisher to dis- 
cover and imitate the fly they prefer.
