Even in late summer the temperature of the water 
in the (ice-free) northern fiords remains very low. This 
fact is illustrated in the groups of serial readings taken 
during a visit of the same party to Nachvak Bay. One 
such group is represented in a

From these (hitherto unpublished) observations obtained 
in 1900, it appears that the water of the northern fiords, 
at depths greater than about twenty fathoms, never rises 
sensibly above the freezing-point of fresh water. 
There is little doubt that the cod does not travel far in 
its annual migration. After spawning, the school simply 
moves out into deeper water on the slopes of the con- 
tinental plateau or on the Grand Banks. There in depths 
of from eighteen to seventy fathoms they browse about.
