Fig. 36. — Lake Champlain at Plattsburg, N. Y. The marsh grass is the 

 narrow-leaved wild rice {Zizania aquatica). The plants rise only a foot or 

 two above the surface of the water. This species is distinctly smaller than 

 the wide-leaved wild rice (Z. palusfris) found so abundantly in the marshes 

 around Washington. 



Fig. 37.— The shore of Lake Champlain at Plattsburg, N. Y. The
