fish up to the time when it becomes necessary to transfer 
them to the waters for which they are intended. While 
hatching the eggs of the California salmon in hastily prepared 
apparatus in the headwaters of the Potomac, we secured a 
number of adult trout which have been placed in the ponds 
of Druid Hill Park. We hope to be more successful with 
these. Mr. Alexander Kent, in 1 873, captured in the same lo- 
cality a large number of trout, and successfully transferred 
them to ponds which he had prepared for their reception in 
Green Spring Valley. They soon became completely domes- 
ticated, and for some time Mr. Kent was quite successful in 
their propagation. Although this year’s distribution was very 
much smaller than that of the previous years, yet many local- 
ities were reached and quite a number of applications were 
filled, which could not be met in the distribution of the year 
previous. As in several localities the introduction of brook 
trout is quite a doubtful experiment, we have decided to 
await the results of these experiments before making further 
expenditures. 
Land-locked Salmon — ( Salmo solar sebago.) 
Our limited experiments in preceding years have demon- 
strated the capacity of the land-locked salmon to live in 
warmer waters than can be endured by the other varieties of 
the salmon family. As the land-locked salmon grow more 
rapidly and attain under ordinary circumstances a greater size 
than the brook trout, and as our experiments indicate that they 
are a hardier fish we have determined to devote more attention 
to their introduction. During the year we secured from the 
eggs presented to the commission by the United States commis- 
sioner twenty-six thousand five hundred, which were distrib- 
uted as will appear in the accompanying table:
