Young Rainbow Trout in New York
Aquarium Do Wonderful Feats.

Aquarium Do Wonderful Feats.
What little trout can do in the way
of jumping and in the way Of swim
ming up hill against a current was
shown lately in the case of a lot Of
agile youngsters at the New York
aquarium, says the Sun. Those lit
tie brown trout, two inches or there
abouts in length, would jump a
height equal to their own length up
a waterfall from an inch pipe seven
inches long, and then swim up the
plRe to the trough above. But some
skSe rainbow trout Matched at the
aquarium have lately done some
thing much more remarkable than
that.
Shad eggs at the aquarium this
spring were Matched in jars from
which siphon tubes ran to tanks
close by. As the fishes were Matched
out they rose naturally to the top of
the water in the jar, where they were
caught in the current setting toward
the opening in the siphon tube, and
siphoned off into the tank.
A half-inch foot-long glass tube
rising through an opening in the top
Of the jar formed a part of the siphon,
to the top of this glass tube being at
tached a rubber pipe to form the
curking part. This rubber tube,
which was half an inch in diameter
inside, ran up to and over an iron
rail, on which it was supported, curv-
ing down from there and rising again
in an upward curve to the edge of the
tank, upon which the pipe again
rested, the end of the pipe being car
ried down under the surface, in the
water of the tank.
While there are at the moment ne
eggs in process Of Matching in them
the jars are not dismantled, but tn,
water is kept circulating through
them, and young fishes are shown il
the tanks. Thus there are now il
one Of the tanks a lot of young rain
bow trout. They were Matched on
here last February, and the bigges
are about p inches in length.
These little rainbows are all tn
time lettering around the opening 0
the siphon tube. through which
current is always flowing, Just as tn
fishes in any aquarium tank may b
found around the tanks intake; an
they are all the time trying to max
their way up the pipe, as they woul
try to make their way up the currer
of a steam in nature. Two Of then
hSncluding che Ct tie very bigges
lsil-ast weel did r'cre their way frol
this tank through the siphon tul
and over into The jar with which II
tube connects.
To do this these two little rainbo
had to swim against the curre1
through a pipe scarcely greater in d
amcter than their own width wit
pectoral fms extended, this mario
pipe being nearly three feet in lengt
and presenting to them a total ri
of eight inches or morein two ascen,
ing curves. 1t was a steep rise f
them for the first few inches Of II
pipe, to where it rested on the ed
ofLthe tank, from which point tn
slid down into the valley formed
the downward curve Of the hose, on
side the tank; while from there tn.

of the hose, the steep incline to whe
the hose was carried over the supper
ing bar. Once over that, Of courl
they couldn't do otherwise than drc
head first, down the glass pipe in
the jar.
The Matching jars are like big, ia
wide-mouthed bottles, with scr
tops, through which run the inta
pipe and the siphon tube. 1t w

turn them to their tank.
