THE CALIFORNIAN SALMON. 
food, will prevent both salmon and trout from rising readily 
to the fly, and until the rivers are well-stocked with fish, 
fly-fishing may not prove very successful; but, whatever 
the variety of salmon, it is likely that the habits and even 
the flavour of the fish, will soon come to be what the climate, 
food, and other circumstances will make them. It is a 
known fact that in some of the Scottish rivers, certain 
tributaries produce much finer trout than others ; the 
difference being so marked that an experienced fisherman 
will, at a glance, tell the stream in which the fish has been 
caught. 
After this report was in type, I found in the January 
number of the proceedings of the Societe d' Acclimatation 
for the year 1878, a short paper by M. Raveret- Wattel on 
the Californian salmon, which gives some valuable informa- 
tion, a portion of which I have translated for insertion 
here. M. Raveret-Wattel states that: — 
“ Besides having well-marked specific characters the 
Californian salmon is distinguished from the Atlantic 
species by some differences in its habits, but above all by a 
special aptitude for living in a much warmer climate. "We 
know indeed that the Salmo salar — of which the abundance 
in the North gradually diminishes as we go South, begin- 
ning say from 55 deg. of latitude — descends but little beyond 
42 deg. ; which explains its absence from the waters of the 
Mediterranean the Straits of Gibraltar being about the 
36th parallel — and also in America from the streams falling 
into the Gulf of Mexico. 
The i Salmo quinnat on the contrary is abundant about 
35 deg. of latitude, and is found beyond 30 deg., which 
gives good reason to think that it may be acclimatised in 
the valley of the Mississippi 
“ Tlie Californian salmon will bear very great heat without 
inconvenience. In July and August it is seen in great
