An underground railway for Berlin is
being discussed by German engineers.
It is estimated that at least 1 ZOO, 600
pounds of rubber are annually used for
bicycle tiers.
The telephone cables laid beneath the
streets Of Berlin are estimated to meet
the requirements 80, 900 subscribers, the
present number being 5000.
Coal in the Province of Almeria, in
Spain, is so dear that there is a great re-
joicing over the discovery of an inferior
quality in large vein near Albanchez.
A recent English invention is a
machine which bends tubes without tho
necessity of filling them with some yield.

An electric car in st. Paul, MINI.
while passing the end of bridge in
heavy rain recently, was struck by light

Among the novelties is an infatable
rubber chamber for bathers. It passes
around the bust underneath tho arms,
making it possible for bather to float

Herr Bombel, an apothecary and chem.

Some of the single plates of armor for
the armored cruiser Maine, building at
the Brooklyn IN. " Navy Yard, will
weigh fifty tons. A special crane is in

the Maine's armor. The crane will be
mounted on a railway running around
the edge of the stone dry dock.
The rate of growth of corals is diff
cult to estimate. At the meeting of the
Academy of Natural Sciences, of Phila.
delphia, Professor Heilprin exhibited a
specimen of Porites astrpoides which
had been taken from an anchor cast in
the autumn of 1885. He estimated that
the annual amount of increase was,
scarcely one.twentieth of an inch.
An attempt is to be made by DIR. II.
Koplik at the Eastern Dispensary, stu.
ated in the tenement district of New
York City, to furnish to the poor at a
low price sterilized milk. 1t is hoped
by this means to prevent the appalling
mortality among the children of this
class. The plan was initiated on a small
scale last summer by DR.. Koplik, who
reports favorable results in the majority
of cases.
A machine has recently been invented
by Philadelphia man by which electric
power can be introduced into q dwelling
house, or, in fact, any building, with
but slight expense. The basis of the in.
vention is practical use of the power
of atmospheric gravity. The gravity, or
weight of the atmosphere at sea level,
will raise water in vacuum thirty. three
feet. The invention consists of pro-
cess of forcing water out of vacuum
placed on the roof of q building and !
keeping the air out at the same time. |
The water is forced to the vacuum, is
then driven into tank, and in descend
ing has sufficient power to drive wheel.
Below the wheel the water can be col
lected into a shallow tank and led back
into the tank from which it first came,
forming a continuous stream.
