FISHES OF THE CONNECTICUT LAKES. 73 
A. Depth, 80 feet; was selected as typical of the open body of the lake, and 
always accessible. 
B. Depth, 90 feet; near the influence of rocks. 
C. Depth, 80 feet; was in touch with the shallow and warm water of the 
outlet. 
D. Depth, 140 feet; was located in the deepest part of the lake. 
E. Depth, 100 feet; was chosen to secure the plankton characteristic of the 
large and quiet body of water lying in South Bay. 
F. Depth, 30 feet; was in the environment of a sandy shore, and to secure 
such plankton as the Main Inlet might be pouring into the lake. 
Plankton was also taken from time to time from 21 special locali- 
ties, indicated by Roman numerals on the map, distributed and char- 
acterized as follows: 
I. The shallow marshy area at the mouth of Mud Pond Brook, characterized 
by Sagittaria latifolia and S. graminea. 
II. At the mouth of shallow pool on north shore, which was fed by springs, 
and characterized by Myriophyllum farwellii, Utricularia vulgaris, and Sagit- 
taria latifolia, to determine what plankton was supplied from this source. 
III. Mouth of Round Pond Brook. 
IV. Lower reach of Main Inlet. Vegetation of Potamogeton amplifolius, P. 
nuttallii, Sparganium simplex angustifolium, Eleocharis acicularis, Nymphea 
advena, and N. hybrida. 
V. Immediately off the mouth of Main Inlet. 
VI. Surface tow of open lake. 
VII. Surface tow of open lake. 
VIII. Surface tow in West Bay. 
IX. Thirty feet of water, near shallow cove of West Bay. 
X. Shallow cove of West Bay, characterized by Myriophyllum alternifiorum 
and Nymphea advena. ; 
XI. Near outlet, over 30 feet of water. 
XII. Protected waters of South Bay, 15 feet deep, among Potamogeton 
pusillus, P, spirillus, and Myriophyllum alternifiorum. 
XIII. Protected waters of South Bay, 15 feet deep, characterized by 
Myriophylium alterniflorum. 
XIV. Protected water of Mast Bay, sparse growth of Chara coronata. 
XIVa. Wave pool on east shore. 
XV. Water of Round Pond Brook before entering First Lake. 
XVI. Dead water of Main Inlet above the lake before it enters the region 
of vegetation. 
XVII. Rapid water of the Main Inlet. 
XVIII. Water of Alder Brook. 
XIX. Water of lake off Alder Brook. 
XX. Bed of Potamogeton nuttallii in West Bay. 
XXI. Bed of Potamogeton nuttallii and P. pusillus in South Bay. 
Second Lake: 
(a) In East Cove, depth 15 feet, among Chara coronata, Potamogeton ampli- 
folius, P. prelongus, P. spirillus, Nymphea advena, N. hybrida, Myriophyllum 
spicatum. 
(6b) In rapid water of inlet. 
(c) Still water of inlet in beds of Chara coronata, Potamogeton amplifolius, 
P. nuttallii, Batrachium trichophyllum.
