SHORE FORMATION OF EQUISETUM LIMosUM.—In the upper ( 
lake, the third of the series and at the head of the chain, amost luxurat 
growth of Lguzsetum limosum has been noted. This plant takes 
place of Scirpus lacustris over large areas and produces a character 
shore and bar formation. In some places it is the only plant gro iy 
over areas many acres in extent. It reaches out into five or six feet 
water and fringes the shore to a depth of four or five rods or even mort 
Much of the plant is var. polystachyum Briickner, while the type 8 
rather more abundant. Nothing like this has previously been me 
with during a rather extended experience among the lakes of Minae 
sota. Commonly the plant, while abundant enough, does not produc 
a solid formation but is scattered amid sedges, rushes and al 
grasses. At upper Cullen lake it covers territory doubtless @ Bee 
mile or more in extent, to the total exclusion of any other archegon 
and of allmetasperms. This gives a peculiar and highly archale 
to the shores and bars of the lake in question.—ConwayY MA®
