Among the many curious inventions
In which electricity plays the principal
role is mentioned a pen. provided near
the point with a minute lncandescent
lamp intended to illuminate a small
space on the paper, and prevented from
shining into the eyes of the writer by
little reflector placed just above it.
In a concert hall of Paris, electric
energy has been put to the novel use
of moving the ceiling. This is In two

Ing cranes. opening the hall TO the glass
roof by day. The opening or closing of
the ceiling Is effected In one minute by
two electric motors.

Survey, says that comparison OF gage
records for a period of twenty years
shows that the land surrounding the
Great Lakes Is being gradually tilted
from northeast TO southwest at such
rate that, of two points 100 miles apart,
the northern rises five inches with ref
erence TO the southern In 100 years. At

/ Inch In ten years. DIR. Gilbert predicts
that, II this movement continues, In
about 5000 years all the upper lakes
will discharge into the Illinois River,
the Detroit and st. Clair Rivers will
flow backward. carrying the water of
/ Lake Erie into Lake Huron, and the
/ Niagara River will run dry.
! A new fireproof paper, made in Ber-
/ lin. Is reported to be capable of resist
/ ing even the direct influence of flame,
/ while 1t may be placed In a white heat
without harm. 1t consists of % parts
/ OF the best asbestos fibre, which Is
washed In a solution of permanganate
Of calcium and then treated with sui
phurle acid and parts of ground wood
pulp, the entire mass being placed In
the agltatlng box, with the addition of
some lime water and borax. After thor
ough mixing, the material Is pumped
into a regulating box. and allowed 10
flow out of a gate into an endless wire
cloth. where II enters the usual paper
making machinery.
i The electric trolley has been a source
+ of great injury to metallic pipes in Its
vicinity. causing their corrosion by cleo
/ trolysis. Recently 1t has been found
that the operation Of the syphon re
corder OF the submarine telegraph ca
BILE at Cape Town, South Africa. was
/ interfered with by the new trolley line.
/ The shore end of the submarine cable
/ for the length of a mile was at mean
/ distance of one-half a mile from the
/ trolley line. As remedy, a second or
/ dummy cable, with an earth plate, was
| laid as nearly as possible ovei the old
/ one. and this effectually cancelled the
/ disturbances. Observations made in
London have shown that the earth's
magnetic field is disturbed over the
whole neighborhood of the City and
South London Electric Railroad, and
/ In the United States the utility OF the
magnetic observatory in the new naval
observatory is threatened by the troll
ley.
