Some Brief Records That Tell Of tho
Worlds Progress.

Worlds Progress.
A typewriter was patented in Eng
land as early as 1714.
The United States leads the world
in the production of resin and turpen-
tine.
Paris has sixty-two electric street
car lines carrying one hundred and
ninety million passengers year.
1t takes five years of hard usage to
wear away a modern wooden pave
ment one inch.
The mines of Belgium yielded elev-
en- million five hundred and fifty-nine
thousand seven hundred and forty-five
tons of coal the first six months Of
last year.
Nearly seven million pounds Of SUI
gar-beet seed are used in the United
States every year.
Greece has so little coal that practi-
cally all Of it's electric power is deriv-
ed from waterfalls.
On an average 1t requires about two
productive acres of land to support
each inhabitant Of a country.
The Italian government plans to ex-
pend twenty million dollars to develop
| it's first naval base on the Adriatic at
Ancona.
A wire rack for carrying papers, ci-
gars. or other small articles in the hat
has been invented by a Pittsburgh
man.
Work Is under way on the first To-
comotive ever built in Chile. the first
of an order Of five for the government.
Ready-made cyclone cellars Of cor
rugated galvanized iron have been
placed on the market by western
metal company.
A magnetiZed ten-cent tack-ham-
mer was used by st. Louis doctor 10
draw a steel splinter from patients
eye.
| Thirteen tons to the acre is the ay-
erage yield Of onions raised by inten-
sive farming in the vicinity OF Valen-
cia, Spain.
An ozone producing fan, now being
made in Vienna, utilizes DR.. Franz
Fischer's novel discovery that when
air Is much heated and then suddenly
cooled ozone is produced. A combi-
nation Of 4 small fiywheel and air-fan
Is driven by an electric motor, and
sucks in air and sends 1t through
kind of funnel to a Nernst radiator,
giving a heat of two thousand degrees
lC. The heated current Is cooled by
mixing with the air into which II Is
then forced. OF the oxygen passed
through about four per cent Is ozon-
! iZed and this proportion cannot De
/ Exceeded, so there is no risk OF an eX-
nf a
piece of apparatus, weighing not more
than thirty pounds and needing but
small amount of power, Is suff1cient
to purify the air Of large hall.
The downpour Of rain that some
times follows a flash of lightning Is
usually supposed to be due to the
coalescence Of fine drops on losing
their electrical charge, but Laine, q
Finnish observer, has found reason TO
adopt new theory. He coneiuaes
that the thunder jars the drops to-
gether Near Vasa, heavy thunder
storm came up from the east late one
August afternoon, and, as the sun was
unclouded, a brilliant double rainbow
appeared in the east for half an hour,
arching from horizon to horizon. Al
each roll OF thunder the rainbows
seemed to me much shaken, the edges
being displaced and the colors blurred.
This could not be due to the light-
lining. and it seemed that the same
cause might enlarge the raindrops and
disturb the rainbows.
The first sun picture was taken by
Mr.. Thomas Wedgewood in the year
ll793. 1t represents Savoyard piper.
| In 1910 a gold watch was made for
the Sultan Of Turkey, which was five
inches in diameter, and cost more
than six thousand dollars.
Lake Huron holds a curious record
in having more islands than any other
| lake. 1t has at least three thousand.
