Some Interesting Facts About the
Propagation of Spawn.
A Talk About PisclcuIture and the
Wyoming Hatchery.

found the trip n good example of an ex-
petition to the Arctic regions. A hole
was cut in the ice and the fish were con-
signed 10 the waters Of the lake, there to
increase and multiply.
The history ofthese fish is very inter
esting and conveys at once scientific infor-
nation and an illustration of the practical
benefits of the propagation of fish in
Wyoming.
Some days g MI. Gramm received
from the United States branch hatchery
at Worthwhile, Mich, the white fish eggs.
These came wrappedin muslin and spread
on tin trays, the whole being packed in
sawdust and enclosed in a wooden box.
The eggs were partially Matched when
they left Michigan, but the further action
of nature was suspended until they arrived
at the hatchery in Laramie City. There
the eggs were spread on trays in trough
Of clean water from the spring at the
hatchery, and in a temperature of 49,
the life of the fish began. After they
were Matched the young fish looked like a
delicate white thread attached to a mar
rowfat pea, but this pea was in reality the
egg from which the fish had been born.
During the first week of its existence the
young fish lives upon this egg, and grad
ually absorbs it. As soon as the egg is
absorbed the young fish must
be planted, for they will
not live in troughs. Yesterday the
fish were just ten days old, hence their
immediate consignment to a pond was
necessary. At the time they were planted
the thread-like appearance had only
measurably disappeared, two small and
dark spots indicated the location of their
eyes, and their unceasing movements in
the water showed thatfthey were alive
and ready to begin life for themselves.
They were brought here in a large can
partially filed with water, which was kept
from freezing by constant motion. When
poured into the hole in the ice the fish
rapidly disappeared, and obeying the laws
Of nature they sank to the bottom Of the
lake. In a few weeks they will have
grown fins and a month and they will
then leave their beds and begin searching
for 70 cd.
Mr.. Gamm has planted 250,0OO white
fish in Wyoming. To-day he will take
$4,000 to Rawlins, where they will be
planted in Sand Greek lake. The same
number will also be taken to Evanston
next week and planted in the waters of
Bear river. and $4,000 more will go to
Green river for the stocking ofthat stream.
The Wyoming hatchery, located three
and a half miles from Laramie City, is an
institution of which little is known, al
though it is one of the most complete es-
adjustments of its kind in the country.
It is situated near a spring of clear water,
having a temperature of about 4S'
the entire year. The Matching troughs
are of the latest improved patterns
and all of the : appliances are
of the best Mr.. G. F. Slocum, for ten
years with Mr.. B. F. Shaw the celebrated
fish commissioner of Iowa, has charge of
the hatchery and under his personal sup
e~rvision every operation Of the establish
ment has been a success.
In a short time Mr.. Gramm will receive
100000 lake trout eggs and in about fifty
days he will plant so, 900 young lake trout
in the lakes north of Cheyenne. During
the ensuing ten days he will hatch New
England brook trout, sent all the way
from Charleston, New Hampshire and
from the Wisconsin hatchery, and a large
lot of California rainbow trout will also
be sent from the Iowa hatchery. The
streams throughout the territory will
will be stocked with these game fish. The
ultimate result of the planting of game
fish in the streams can hardly be exag-
gerated. The trout will multiply rapidly,
ere long they will exterminate the suckers,
clubs, and other useless fish in these
streams, and in a few years the supply of
trout will be practicable ~inexhaustible.
Wisconsin brook trout were caught last
summer near the ranch of D. B. Dale, on
Little Laramie, that weighed three
pounds, and these fish were but three
years old.
Speakioe of earn. Mr. Gramm was dis
posed to DISCOURAGE the introduction Of
these fish into Wyoming. Said he. s.Tbe

vegetation and thriyes best in warm water
