 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

" 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.
