o4 FISH HARVESTING. 
the Colville Indians Keasoo, by the Chinooks 
Ekewan, by the Clallams Kutch-kutch —the 
Hooked Snout of the fur-traders, Salmo lycaodon 
of Pallas, Zoog. Russ. Asiat. 
When fresh-run, this fish in colour is of a 
silvery-grey lustre; back, overshot with a 
greenish hue; belly, silvery-white; no spots 
on either the back or sides. The hooked nose, 
said to be peculiar to the male fish after 
spawning, is a well-marked, constant, and speci- 
fic character in every fresh-run fish, the females 
having at all times symmetrical jaws. I found, 
from carefully observing great numbers of these 
fresh-run males, that the hooked state of the snout 
differs very materially in fish arriving at the same 
period; and I am quite convinced that large num- 
bers of these salmon do get back again to the 
saltwater after spawning, and that the strange 
change that takes place in the hooking over of 
the snout and growth of the teeth, during their 
sojourn in the rivers, remains a permanent mark ; 
and the vast difference observable in the males, 
at the time of arrival, is simply attributable to 
the fact, that those having the large fanglike 
teeth and tremendously crooked snout are such 
as have been up the rivers perhaps the year before, 
or, it may be, long prior to that period.
