The climate OF Cnlna Is ssiio W pt
growing not only colder but drier.
In the Atlantic Ocean there are about
eighty-three pounds of salt to every tor
of water.
A revolution in coal mining is ex.
pected from the use of a machine oper-
ated by electricity.
There is great demand for metal
furniture of all kinds in Australia on ac-
count Of the ravages of the white ant.
Galvanized wire netting is being large
ly sold for lawn, garden and shrubbery
purposes, for which it is admirably
adapted.
The coolest spot on earth is Verko-
yansk, in Siberia, where the mean win
ter temperature is 1876 degrees below
zero, Centigrade.
As rule it seems that lepers do not
suffer severe pain, and the average length
of life at Molokai, Hawaiian Islands, is
about four years.
Cable messages are received by an in
strumcnt known as the syphon recorder,
which sauirts a small jet of ink on a paper
ribbon as the current is made or broken.
There are said to be at least 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
kept properly painted with good paint,
and the plates properly ''picklcd," 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 few weeks
line of omuibusses run by electricity is to
be started. They will be driven by
storage batteries, and will have seating
capacity for twenty-six passengers.
The thistle at the antipodes seems to
attain most vigorous growth. Its root
penetrates to depth of from twelve to
/ twenty feet; and this root, even when
cut into small pieces, retains vitality,
each piece producing new plant.
A weak galvanic current, which will
sometimes cure toothache, may be gen
Grated By placing a silver coin on one

The greatest electric railroad which
has been planned is the one proposed In
Russia, between st. Petersburg and
Archaugel, a distance of 500 miles. The
plan is to erect stations along the route
for the generation of electricity. The
estimated cost is only about S15, 600 II
mile.
The projected railroad to the summit
of Jungfrau, in Switzerland, contem-
plates the boldest mountain engineering
vet ventured upon. The line, which is
to consist of continuous series of tun-
nels, is intended to rise in a distance OF
a little over four miles from an altitude
of $500 feet above the sea to the lofty
heighth of 1860 feet, with grades Of
from thirty-three per cent. to ninety
eight per cent--or practically perpen
dicular.
A neat application of electricity to do
mestic uses is miniature pumping plant
With the use of no more current thar
suffices for a couple of incandescent
lamps, it will pump one hundred gallons
an hour or so, and keep the house tanl
full withouta particle of attention. These
little electrical devices to Tighten labo
in the household are particularly com
mendable, and as the electrical light anc
power becomes more widely available
will doubtless increase in number ant
utility,
