217 



Depths: 8, 14, 20, 24, 28, 34, 34, 35, 37, 39, 42, 43, 



45, 46, 46, 47, 46, 46, 44, 39, 35, 30, 18 and 6. 



Line MN. From south shore northward in line with fence 

 west of Jordan's barn, 15 soundings. 



Depths: 8, 18, 26, 29, 35, 39, 42, 44, 44, 42, 37, 34, 

 28, 16 and 8. 

 Line OP. From north shore near tallest sycamore, southward 

 to west end of largest clump of willows, 27 soundings. 



Depths: 5, 6, 16, 20, 25, 27, 29, 33, 35, 35, 35, 35, 35, 

 35, 35, 35, 35, 35, 35, 32, 32, 30, 27, 25, 21, 17 and 8. 

 Line QR. This is a series of 15 miscellaneous soundings in 

 the deepest part of the lake and about on a line between 

 Jordan's barn and the middle of the ice-house starting 

 about i distance across the lake from north shore and 

 sounding every 5 oar-strokes or closer. 



Depths: 45, 46, 47f, 50, 50, 50, 50|, 49, 48, 48, 48, 



46, 44, 44 and 42. 



From the above it appears probable that the greatest depth is 

 about 50 feet. It is not likely that a much greater depth than 

 this can be found, and 51 feet may, therefore, be put down as 

 the maximum depth of Lake Cicott. It is said by some people 

 of the neighborhood that the lake is bottomless, and that 

 recently it was sounded with a 400-foot line and no bottom was 

 found ! Others say that bottom was found at <S0 feet, and still 

 others at 60 or 65 feet. 



It will be noticed that the depth increases very rapidly from 

 shore out and that the depth is pretty uniform in the middle of 

 the lake. 



There is very little clean sand or gravel anywhere; up to 20 

 or 25 feet the bottom seems to be pretty well covered with 

 Chara, Myriophyllum, etc., beyond which it is of soft muck. 



Temperatures. — A vertical series of temperature readings was 

 taken at the last sounding on line EF (depth 44 feet), with the 

 following results:
