faces, whether rippled or not. Under “ waves” are included all ruf- 
fled water not breaking into white caps. Under “rough” are in- 
cluded all crested waves. These grades of surface present clearly 
marked distinctions which some forms of plankton may recognize 
and to which they may react. 
Adjacent pools.—On the east and north shores of the large eastern 
expanse of the lake the sand of the beach is piled up in such a way as 
to impound in several places the water which may wash over from 
the lake or find its way into the hollows by seepage or from springs. 
In one of these in the northeast curve of the lake and a similar one in 
the middle of the north shore line the supply from springs is sufficient 
to cause a constant stream to cut its way through the intervening 
bank and enter the lake. The conditions of life in these pools are 
very different from those found elsewhere. The shallow expanse, 
almost unchanging water, and resulting high temperature, 80° F., 
give a peculiar flora. The pools on the east differed from those on 
the north. The east pools were filled with Mougeotia sp., Chara 
coronata, Potamogeton pusillus, Callitriche palustris, Myriophyllum 
alternifolium, and Utricularia vulgaris. The pool on the north was 
filled with Sagittaria latifolia, Myriophyllum farwellii, and Utricu- 
laria vulgaris. 'This pool remained luxuriant throughout the season, 
while those on the east became choked with vegetation and cleared 
through decomposition during the summer. The pools which have 
communication with the lake doubtless are a source of plankton forms 
loving or requiring quiet water of relatively high temperature and a 
dense vegetable environment. 
SECOND LAKE. 
Shore vegetation—tThe shore line of the northern part of this lake 
is of small bowlders along the western shore and the tongue of land. 
A small portion of the eastern shore which receives the sweep of 
wind across the entire lake is a sandy beach. The remainder of the 
shore line and the shore line of South Bay is a turf. The rocky 
shore is characterized by royal fern (Osmunda regalis), sweet gale 
(Myrica gale), speckled alder (Alnus incana) , meadow-sweet (Spirwa 
salicifolia), red osier dogwood (Cornus stolonifera),rhodora (Rho- 
dora canadensis), sheep-laurel (Kalmia angustifolia), and withe-rod 
(Viburnum cassinoides), with a background of black spruce (Picea 
mariana), fir balsam (Abies balsamea), paper birch (Betula papy- 
rifera), and yellow birch (B. lutea), with a very occasional specimen 
of white pine (Pinus strobus). The turf shores were covered with 
the grasses and sedges common to the region. 
Sources.—The visible sources of water are five streams, two of con- 
siderable size—the Main Inlet, or Connecticut River, at the northern 
end of West Cove and a small stream at the northwest curve of
