1t is not generally known that there
are more wagons manufactured in St.
Louis than in any other city of the
country. The entire South and South
west are supplied with wagons of all
kinds from that point In the line of
fancy wagons and carriages, St Louis
manufacturers beat the world, shipping
even to Europe and Australia.
MIR. Shelford Bidwell, in speaking
at the Royal Socicty's conversations in
London, exhibited an experiment which
may possibly explain the intense dark
ness, often accompanied bya lurid yellow
glow, during thundcrstorms. After
showing on screcnsthe shadow of
small steam iot, which was of neutral
gray tint. and OF fceble intensity, he
electrified the iot, and tho shadow be-
camo dense and of peculiar orange
brown hue.
In anilino dyes Prof. Sitting, of
Strasburg. believes he has discovered
antiseptics strong enough to kill bac-
terra in concentration not injurious to
tho human body, and at the same timo
dlHuslve enough to spread over
wounded surface. In o man Of seventy,
whose left leg between the ankle and
tho knee was covered with ulcers which
would not heal, the suppurativo micro
organisms were all destroyed in few
days. and tho ulcers disappeared.

In a recent lecture on ''Marino and
Fresh Water Fishes" noted scientist
said that fish have the power of innu-
encing ono another by sounds and
action. He had observed shoal Of carp
following tho lead OF single one,
which conducted them to quantity Of
food at "a considerable distance away
He had also noticed that certain fresh
water fish, such as trout, were subscrvi-
Ont to ruler, which might DO seen
swimming at the head of his tribe. The
Same was possibly the case with somo
marino forms, like the herring and bass
An extraordinary report comes from
Fort Chippewoyan that the United
States surveyors have established tho
Hist meridian, which forms tho bound
airy between Alaska and Canada, twenty
eight miles farther east than it was sup
posed TO be. / this is true, large area
of gold placer ground would be trans
ferrcd TO the United States. But it
seems strange that SO great an error
should have been allowed to pass in n
region which was we'll known to traders
and prospcctors. strengthening and Min

Tho experiments Of DR.. Tatum have
done not little toward clearing up tho
mystery that has shrouded the physical
mechanism OF death by electricity, He
has made it moro than probabl that
thcre is 4 real difference between tho
effects of continuous and alternating
currents, in that the former seom to Kill

tons OF tho nervous system. DR.. Taturn
has also shown that the difference in
the effects Of tho two classes of current
is far less than some foreign investiga-

Being surrounded by enterprising noigh-
