Map of the eastern end of Lake Erie and the Niagara river showing 

 the location of the principal areas of aquatic plants. The areas 

 are numbered to correspond to the numbers used in the discussion 

 of the vegetation on pages 192-4 of the text. The width of the 

 Niagara river has been exaggerated to make it possible to indicate 

 the location of the weed beds.
