Crustacean Life 



Nl5 



On September 28, 1915, I took two lines of soundings across this lake from 

 the 7-8 inch thick ice. One line was laid from the north to the south shore of 

 its western part, about 500 paces from its western shore. The depths were 

 (maximum depth in italics) : 



42 inches water 1 Bottom few stones and 



J light brown mud. 



Bottom a thinner layer 

 of light brown mud 

 above a thick layer 

 of black mud. 



Bottom as (l)-(2). 



Note. — In February, 1916, I found the water depth a little east of (12) to 

 be 340 inches (20 feet) , the maximum depth found in this lake. 



Hole (1) was 25 paces from the north shore and hole (17) was 30 paces from 

 the low stony point on the south shore. Holes (1) to (9) were 25 paces apart 

 (9) to (17) were 12| paces apart. 



The other line of soundings was laid from the south to the north shore across 

 the east part of the same lake, about 400 paces east of the soundings given above. 

 The result follows (maximum depth in italics) : — 



Bottom brown sandy 

 mud, with a few stones. 



{■Bottom black mud. 



Bottom as (l)-(5). 



Hole (1) was 25 paces from south shore; hole (16) was 20 paces from north 

 shore; holes (1) to (4) and (12) to (16) were 25 paces apart!, the rest 12| paces 

 apart 



It will be seen from these two lines of soundings, that the maximum 

 depth is 20 feet, and that the "deep" (say below two fathoms) lies much nearer 

 the south than the north shore of the lake.
