At speed Of sixty miles an hour a
train covers 1856 feet each second.
The terrific heat of the acetylene gas
blow-pipe Is being used in the welding
Of steel.
The Slaby-Arco wireless telegraph
system is being installed by Russia on
the Baltic Sea.
A side wind retards the speed Of n
train more than head wind, because
Of the flange friction it produces.
The volcanic dust from Mont Pelee
proves to have little fertilizing value.
An analysis by an American engineer
Of specimens from Barbados, where
though ninety miles away-the fall on
May ! was about three inches. has
shown only O.675 per cent of potash
and O.l41 of phosphoric anhydride.
A large blank on the meteorologic
map of the world has just been filed
by the organization of a weather Of
flee under the Argentine Department
OF Agriculture. An American, Walter
q. Davis, is at the head of it, and daily
weAther-maps are published, covering
nQt only Argentina proper, but Patago-
mia.
The nasal passages are stated to
have a surface area Of not lesG than
twenty square inches. A new proven
tive of hay fever is the rubbing with
surgical cotton twice daily Of us much
of this inner surface, or mucous men,
brane, as can be reached. The mas
sage hardens the membrane, lessenng
it's Over-sensitiveness.
New Jersey has long been famous
for it's mosquitoes, and 1t seems appro-
pirate that the State should lead in the
scientific warfare on the malarial
pests. The Legislature has appro-
priated $4,000 for preliminary inves-
tigatiOn Of the subject; but the whole
sum being, for some technical reason,
not available, the Governor has set
aside $1,000 from his emergency fund
to get the work under way. A scien-
tific investigation is to be made in a
malarial district of the State, where
the dreaded anopheles Is abundant,
and the result of his inquiries is ex-
pected to guide the future steps In the
campaign.
How the electric waves used in
wireless telegraphy follow the earth's
curvature is still an unsolved problem.
Il. Lasher suppOses that the waves run
along the surface Of the earth, and es-
pecially of the sea, in the same manner
Int Col
Of the electric energy enters the earth's
surface as part Of 1t penetrates the
surfare of the wire. A suggested test
Of the theory is signaling between two
balloons when the difficulty OF COM
munieatiOn should Increase with the
height The electrical oscillations he
ing ut right angles to the wire or
earths surface, another interesting ex-
pertinent would he the sending OF sig
mails up a precipice, using both horh
zOntai and vertical antennae.
Many details of the back wardness OF
the worlds metropolis in those applica-
tions Of practical science with which
We are so familiar in America have
been pointed out from time to time
None OF them is, perhaps, more sur
prising than the absence OF telephone
connections among the London police
stations. The householder who finds a
burglar ON ibis premises cannot call up
the police to assist him. In truth, few
private houses in London have tele-
phones, AID recently the operations of
the police in an important burglary
case We're much hampered by the lack
Of telephone service mt Scotland
Yard. The fire department refuses to
allow private alarm connections with
the fire stations. English conserva-
tism is blamed for the absence Of
many Of the conveniences Of modern
life which the progress of science has
afforded in almost every other great
city more abundantly than in London.
