A Mexican professor of physics
proposes 70 foretell earthquakes by
connecting telephones TO the pipes of
deep artesian wells, and to metal plates
sunk deep In mountain crevices. Any
unusual noise in the bowels Of the
earth would be audible in the tele-
phone, and would indicate trouble.

1t Is related that, in 1891, a young
electrician, now in Paris, on looking
through Carnegie's great steel rail
plant at Bpaddock, Pa, casually sug-
gested that electricity could be made
70 operate the widely separated pieces
of machinery at a saving of many thou
sands year. A week or two ago An
drew Carnegie visited the plant for the
first time in two years, and saw cleo
tricity doing the work. This improve
ment, together with others, IL is said,
makes IL possible for eight men to do
the work 300 did in 1891.
"A handy little device has been
b<onght out for preventing the waste
a curreng that eftsn goes on in the
elseArie whiting Of hotels and large
buildings. In a hotel bedroom, eel.
lsrs and other places where persons
arc constantly passing in and out and
requiring light for only short periods
IL not infrequently happens that the
light is switched on and left burning
sometimes for many hours, TO no pur'
pose The apparatus which makes such
waste impossible is small piece OF
cloclrworlS, by means Of which an in
candescent lamp is automatically
switched off in half an hour, an hour,
or any prearranged time. 1t can be
included in any ordinary circuit in
stead of the switch, and at very mod
crate cost.
A miniature electric yacht has
lately been placed on the market. II
is &c inches in length and 6lI inche:
beam, and is guaranteed to beat any
other boat Of its size. 1t is driven by
a tiny motor and one cell Of a special
boat battery. The motor is suspended
on bracket and geared direct with
the propeller shaft. Motor, gearing
and battery can all be taken out and
replaced within a minute. The bat
terry gives enough current TO propel the
boat between one and two hours. II
gives no trouble whatever, as from IL
construction there can be no tipping
over of acid and no breaking of glass
Jars. The boat travels at the rate o.
| about three miles an hour. The pro
pellor is 2A inches in diameter, anC
has two blades set at a as degree pitch
The whole appearance of the tiny Graf
is trim and workmanlike-in fact, i
has been designed and built under thu
direct supervision of United States
naval engineer. 1t is claimed that a
an easy running boat il can not b'
equalled, and for boys, beside being I
source of amusement, will be also ont
of instruction.
