processes for multiplying the fish supply Of
every kind are constantly being discovered
with results that are really wonderful.
FEEDING fisH.
Thus far nothing has been said Of the feeding
Of fish artificislly, which, together with copi-
Gus water supply, may be said to constitute
what is equivalent to so-called intensive
farming on land Given a flow of 100 gallons
of water per minute and plenty Of liver and
scraps thrown in and you can raise ], 900 pounds
OF trout in pond ten feet deep, ton feet long
and ten feet broad replacing them with small
ones as rapidly as they reach marketable size.
1t can be done "ery probably, too. The time
Is looked forward to, and it is not far away,
when every farmer will look upon an acre Of
water as he does upon an acre Of land, expect
ing SO much yearly yield from il, whether il 10
pond, lake, river or estuary.
EXPERIMENTS IN THE YELLOWSTONE.
At the present time the government is &C
lively engaged in piscicultural experiments in
the Yellowstone Park. In the midst Of the park
lies Yellowstone lake away up on volcanic
plateau covered with lava mostly. The fishes,
which " one time probably lived in the other
lakes thereabout, were presumably all killed by
one in them now. They would ascend the rivers
which flow from the lakes and SO people the
waters but for mighty cataracts which bar their
passage upward. These tenantless sheets Of
water are being stocked with ,iand-locked sal
mon and other species, giving each sort lake
PELICAN, WORN AND TROUT.
About Yellowstone lake itself, however, there
is quite piscatoria; romance 1t lies on this
side Of the great Rocky mountain divide
and is occupied in large numbers by trout,
which have actually climbed over the mountain
chain from the Pacific side, being obliged to
ascend for that purpose an elevation 5000 feet
above the sea level. This extraordinary feat
was accomplished by ascending Pacific creek

swamp at the summit Of the ridge in a time of
Hood, and travelling down Atlantic creek on the
hlther side into the Yellowstone lake. No other
kind Of fish besides this trout exists in this
lake, owing to the impossible falls of the yell
towstone river. 1t is commonly infested by
parasitic worm. which renders the meat dis
eased. 1t has been demonstrated that
this worm comes from the pelicans. which
are numerous there. The pelican has the
worm in its intestines, the eggs OF the parable
are voided by the bird the fish swallows TIE
eggs, the eggs are Matched in the fish, the peIi-
can eats the fish, the worms IN the fish attack
the pelican. and SO on ad infinitum. The worm
requires both the fish and the bird for the
completion Of its life history, and it is sug-
gested that the best way to get rid OF the para

eaten by man. Parasites Of the tench are sold

AT THE WORLDS FAIR.
The fish commissions exhibit Of aauaria at
the Chicago fair is to be immensely attractive.
As thus far conceived, though details have not
been perfected, the annex fo- the purpose will
be $50 feet square and entirely of glass. There
will be 1000 feet in length Of glass tanks filed
with all sorts Of water creatures. one-halt being
devoted to marine life and th2 other halt to the
display Of fresh water specimens. The visitor
will walk betwee.: two lines of aquaria the en-
tire circuit OF the building. In the middle OF
the latter will be great tank full Of salt water
brought all the way from the Atlantic.
