The federal forest service has de-
veloped a process for making paper
from scrub pine, which covers extern
sive areas on the southern Atlantic
seaboard and Is little used except for
fuel.
A London scientific journal that
analysed samples of snow taken from
the roof Of its building found that
weekday SHOWS contained about five
times the impurities of those gathered
on Sundays
1t has been satisfactorily demon
strated that the blue rays from mer-
curry vapor lamps kill bacteria and
sterilize water in which the lamps are
placed without appreciably increasing
It's temperature.
Because Of an increase in the num-
Der Of cases Of malaria, the city of
Leipzig has declared war on the mos
quito and will fine any resident who
fails to carry out certain regulations
intended to exterminate the insect.
Because the blowing out Of fuses has
caused panics among passengers, new
cars being built at st. Louis are carry
ing the fuses on the outside. the smoke
and discharge material passing
through Slated openings to the cutter
air.
Hitherto the use Of the falls Of the
river Rhone for the production Of cleo
trio power has been almost confined
to the Swiss part of the stream, but a
project is on foot for the utilization
of the falls at Genissiat, in French ter
ritory, for the production of electric
power to be sent to Paris. The falls
have a descent of over 200 feet, and
it Is estimated that they will produce
10000 kilowatts per hour. an amount
of energy the production Of which
would demand the consumption Of
more than 200 tons of coal.
Sir William Ramsay and r. W.
Graw have liquefied and. they believe.
solidified the emanation from radium,
which is popularity famous for chang
ing spontaneously into helium. The
boiling point Of the emanation at at
mospheric pressure Is 4S.5 degrees be-
low zero cenugrade. The liquid Is
slightly phosphorescent, but II it is
cooled with liquid air 1t begins to glow
with a white light, which passes first
to yellow and then to orange. In the
microscope the light resembles little
electric arc. On removing the liquid
air the colors succeed each other In
the reverse order. and a blue color APP
pears, followed by change as IL the
crystals of a solid were dissolving.
The experimenters believe that the
brilliantly luminous substance seen is
the emanation in the solid state.
Since 1906 diamonds have been
found In Pike County, Ark, In rock
similar to that of the diamond fields
of South Africa. 1t is peridotite of
igneous origin which has been pushed
I'D through carboniferous and creta-
ceous formations. In some places the
rock Is very hard and dense, but In
others 1t has weathered to a soft yell
lowish and greenish material 20 to %
feet deep. About 600 diamonds have
been found in this rock. the largest
weighing 6h carats. The usual colors
are white, brown and yellow; but one
blue diamond and several black ones
have been found. One bore for ex-
ploration has been driven to depth
of 205 feet. AS to the prospects Of
more stones being found by deeper
mining, biologists only say that the
spasmodic exploitation thus far seems
to indicate a good promise.
