[13] A FOREIGN REVIEW OF AMERICAN FISH CULTURE. 489 
To judge from the nature of the waters which are continually inhabited 
by the California salmon, it seems certain that these fish could be sue- 
cessfully introduced in a large number of water-courses. In the United 
States these salmon seem to spread very successfully in the Eastern 
States, where few rivers have as turbid waters as the Sacramento, or as 
hot water as the San Joaquin. Furthermore, the long journeys annu- 
ally undertaken by the California salmon, the strength and energy ex- 
hibited by these fish during their migrations in the waters of the Sacra- 
mento and McCloud Rivers, all prove that no other kind of fish equals 
them in the capacity of ascending the rivers for a considerable distance 
from the sea for the purpose of spawning. 
The Shoshone Falls on the Snake River, one of the tributaries of the 
Columbia River, is the point where the salmon stop and where large 
numbers of them spawn; and these falls are more than 700 miles from 
the sea. It does not seem impossible, therefore, that the California sal- 
mon might live and flourish in the Mississippi, the tributaries of which 
river would afford spawning-places at a shorter distance from the ocean. 
As for waters of the Gulf of Mexico, where its annual migrations would 
take this fish, they are not any hotter at a certain distance from the mouth 
of the Mississippi than the waters of the sea along the coasts of New 
England. These considerations have induced the Fish Commission to 
make vigorous efforts to propagate the California salmon in the South- 
ern States, where a special establishment will soon be created for the 
artificial propagation of these fish. 
So far this salmon has been introduced into a large number of water- 
courses; and also into several lakes having no communication with the 
sea, where they have nevertheless begun to increase. It will hardly be 
necessary to point out the great importance of acquiring for our own 
waters a species of fish so remarkable and valuable in every respect.
