A revolution in coal mining is ex-

Cable messages are received by an in
strument known as the syphon recorder,
which squirts small jet of ink on a paper
ribbon as the current is made or broken.
There are said to be at least a hun
dred thousand acres of phosphate rock
scattered through the western part of
Florida. The deposits average ten feet
in depth, and are rich in phosphate of
lime.
Experts claim that if steel ships are

and the plates properly 'pickled, they
would last as long as iron, otherwise
they would deteriorate more rapidly than
iron ships.
Electric traction is said to be fairly
booming in London. In a few weeks a
line of omuibusses run by electricity is to
be started. They will be driven by
storage batteries, and will have seating
capacity for twentysix passengers.
The thistle at the antipodes seems to
attain most vigorous growth It's root
penetrates to depth of from twelve to
twenty feet; and this root, even when
cut into small pieces, retains vitality,
each piece producing a new plant.
A weak galvanic current, which will
sometimes cure toothache, may be gen

acidulated water will increase the effect.
The greatest electric railroad which
has been planned is the one proposed in
Russia, between st. Petersburg and
Archangel, distance of 500 miles. The
plan is to erect stations along the route
for the generation of electricity. The
estimated cost is only about SIS, 900 II
mile.
The projected railroad to the summit
of Jungfrau, in Switzerland, contcm-
plates the boldest mountain engineering
yet ventured upon. The line, which is
to consist of a continuous series of tun-
nels, is intended to rise in a distance of
little over four miles from an altitude
of $500 feet above the sea to the lofty
heighth of 13, 600 feet, with grades of
from thirty-three per cent. TO ninety.

A neat application of electricity to do.
mestic uses is miniature pumping plant.
With the use of no more current than
suffices for couple of incandescent
lamps, it will pump one hundred gallons
an hour or so, and keep the house tank
full without particle of attention. These
little electrical devices to tighten labor
in the household are particularly COM
mendable, and as the electrical light aud
power becomes mere widely available,
will doubtless increase in number and
utility.
