" This fine fresh- water fish is abundant throughout the State, 

 inhabiting pretty much every stream and pond, avoiding rapid 

 currents, and delighting in still, deep waters, with a sufficient 

 growth of spatter-dock to conceal them from the sun's rays and 

 general observation, while Aey lie in wait for any unlucky min- 

 now, shiner, roach or chub that may approach within a limited 

 number of feet of them."
