with. Then by covering with boards the sun-hght was mostly 
excluded, and they were left to hatch themselves. The fish 
hatched well and did well,.and by giving them free use of 
three successive ponds, they sortéd themselves as perfectly as 
could be done by hand. There was a fall of eighteen inches 
between the ponds, so that when they once went down they 
could not return. 
The plan was also tried of letting the fish have a chance 
to go on the spawning-beds themselves, and then turning 
them off when they had got through, but this did not yield 
so many fish as the method last stated. Another method was 
tried by taking the eggs by what is called the Russian method, 
or dry impregnation, and placing them immediately in the 
ponds, and with a turkey’s wing making the nest and covering 
the eggs in the same manner. This plan was more successful 
than letting the fish into the pond to spawn, and turning them 
out when they got through. A method of raising the smail- 
fry was tried and found to work well; that was by taking 
the fish out of the trough or boxes as soon as they began to 
feed, and placing them in a car or box that had previously 
been fastened in the race or pond where there was a good 
current’ of .. water. (At ithe |: upper Mend siotithis,\car ~wasgal

When the fish had grown to an inch or more in length they 
were removed to the ponds or streams where they were to

good satisfaction with salmon-trout, land-locked salmon, and 
the Selmo Salar, and especially with the California salmon.
