would seem to indicate that conditions in the ocean had affected their survival since 
it is unlikely that unfavorable conditions in fresh water would have been so distributed 
over a number of years as to have brought about this result. The facts that both 
species make the seaward migration as soon as they come out of the gravel in which 
the eggs are laid, that they spend practically all their lives in the sea and have some- 
what similar feeding habits, lend some support to the hypothesis that the coincidence 
of poor runs may be the result of oceanic conditions affecting the survival of both 
species equally. 
This district includes the waters northerly and easterly of a line from Lemesurier 
Point to Ernest Point, thence across Onslow Island to the southern extremity of 
Etolin Island, thence along the watershed of that island to its northern extremity, 
and thence across Chichagof Pass to East Point on Woronkofski Island and the 
boundary of the Stikine River district across the northern end of Zimovia Strait and 
Eastern Passage. (See fig. 45.)
