PL II. — I. In the slow meadow streams are diving beetles, 

 nymphs of dragonflies and damselflies, burrowing mayflies, 

 water striders, tadpoles, and leopard and green frogs along 

 the banks. 2. Pond shallows; near shore duckweeds cover the 

 water like a blanket and dot the water surface beyond; here 

 the lily pads are floating hatcheries for the eggs of snails and 

 water insects; sunfishes and sticklebacks hide below them.
