SALMON. 41 
its entire length, is a light steel-blue; shading 
off on the sides to a lighter tint, that merges by 
imperceptible gradations through grey to silvery- 
white on the belly; blushed over with pink, that 
disappears soon after death. Back, above the 
well-defined lateral line, thickly spotted with 
black, the spots being like stars with rays of 
irregular length; but I have very often seen the 
spots extending beyond the lateral line, and even 
on the white of the belly. Opercula, all the fins 
and the tail more or less spotted, and of a pinkish 
hue, the anal and pectoral fins tipped with 
black. The general appearance of this salmon is 
that of being very thick for its length, the dorsal 
outline slightly arched, forming almost a notch 
with the tail. 
Soon after our commencing work, I was en- 
camped for many months on the banks of the 
Chilukweyuk river, a tributary to the Fraser, 
having a short but rapid course through a rocky 
valley. . 
In June and July salmon ascend this stream 
in incredible numbers, filing off as they work 
upcurrent into every rivulet, fillmg even pools 
left on the prairies and flats by the receding 
floods.
