the hatchery buildings. Its depth was not ascertained but 
a 7 :

West or Sueparp Point (Fietp Nos. 
225, 238). Fias. 15, 16. 
In this habitat the shore is devoid of vegetation, except in 
limited areas where there are clumps of Black Willow (Salva 
nigra var. falcata), Buttonbush (Cephalanthus occidentalis), 
and Iris (/ris versicolor). The shallow water near the shore 
in such places, usually contains a fringe of Swamp Loose- 
strife (Decodon verticillatus). Occasionally a mass of vege- 
tation extends into the lake, forming a point. This consists 
of Pickerel weed, American Bulrush (Scirpus americanus) 
and Water Willow. Scirpus smithi may also be present (see 
Fig. 15). Away from the shore, where the water is from 
2 to 4 feet deep, there is an association of Water Willow, Bul- 
rush (Scirpus occidentalis) and Piekerel-weed (see Fig. 
16). The bottom is of hard sand with a few boulders. The 
sandy bottom contained a large number of. species of 
mollusks.
