(Lysimachia terrestris (L.) B. S. P., L. thysiftora L.) ? and 
water hemlock (Cicuta bulbifera L.). Next to the water the 
"broad-leaved arrow head (Sagittaria latifolia Willd.) was 
abundant. Sedges and grasses were Well represented in species 
and individuals ; the most conspicuous of the former were the 
bulrush (Scirpus lacustris L.) and tall cotton grass (Eriophorum 
polystracbyon L.) ? both very common toward the head of the 
lake. The tall marsh grass (Spartina cynosuroides (L.) Willd.) 
grew to great height; and there were a few plants of the wild 
rice (Homalocenchrus lenticularis Michx.), also abundant in 
the upper lake regions. Trees were represented only by the 
speckled alder (Alnus incana (L.) Willd.) and American aspen 
(Populus tremuloides Michx.) ; these and two species of willows 
grew where the strand zone was narrow and the soil coarser. 
As one passes around the island to the south-east point the 
strand zone becomes narrower and the soil sandy and the plants 
of course are not as rich in numbers or in species. On the 
north side the sandy wash produced three species in very small 
numbers not found elsewhere on strand: the black night shade 
(Solanumi nigrum L.), the great water-dock (Rumex brittan- 
nica L.), and the field horsetail (Equisetum arvense L.)
