The world still has a considerable
supply of coal. Germany is credited
with $50, 900, QUO, 600 tons, sufficient to
last 2,OUO years at the present rate of
consumption; Great Britain and Ire
land claim 1913, ZOO, 600, 600 tons, with
an annual consumption about double
that OF Germany; Belgium has %, 900,
600, 600, tons; Frsnce, 19, 1000, 600, 600;
Austria, 1900. .OOo, 600; and Russia
40, 600, 900. North America is believed
to have 68l, ,oOO, 600. QUO, 900, tons, more
than the total of the other countries
named. 1t Is the tremendous increase
in the use of coal that iustifies alarm,
for, while the supply of the, Urited
States would last 1900 years at the
rate OF consumption in 1905, it will
be exhausted within century il the
rate of increase of the last 80 years
continues. No estimates of the coal
of other parts of the world can be
made, but Asia Is known to have an
enormous store.
Probably no substance is adapted
to a greater variety of uses than
rubber. but Its applications are
restricted by the limited supply and
high cost. Among the purposes for
which 1T has great advantages but is
not likley to be extensively employed
is that of paving roadways. A rubber
pavement laid at q London railway
station is 1881 was in 1902. worn down
to five-eighths of an inch inIits thinn-
est place. Notwithstanding the scare
ity of the material, the cost was less
than three times as great as that of
wood, and its life has been more than
twenty years instead of the four years
which the wood or asphalt would
have endured.
The unique floating ice barrier
pushed out from the Mysterious
Antarctic land was found by Capt. |
Scott's expedition to extend 500 miles
westward from the volcanoes Erebus
and Terror, and more than 400 miles
toward the Pole, reaching beyond 80
degrees II minutes south lat. The
front rises 10 to $50 feet above the
water.
Even the best eggs may cause diges-
tive disturbance through the idiosyn-
Grassy of certain individuals, but LIE
Cog, a French Psychologist reports
that some eggs develop zeal poison,
which he names ovotoxine. Its pre-
sence is usually marked by peculiar
putrid odor, which in the white may
be so slight as to escape notice. The
toxine may be present in fresh eggs, |
but much more often occurs in those |
that are stale, and mixing long
broken eggs with cream-as is done
so frequently by bakers-is especially
liable to produce the septic altera-
ticn. Feeding hens with putrid or
diseased meat is fruitful source of
the infection of the white of eggs.
This investigator would condemn all
desiccated and preserved eggs, and
as there is no way of distinguishing
safe fresh eggs, he would insist that
all eggs to be eaten should be we'll
boiled or sterilized by other thor
ough cooking, and particularly that
raw eggs should not be used with
cream in pastry.
The common sunflower, a native of
Peru and Mexico, is gaining favor in
parts of Europe as a febrifuge. In
Russia, where the plant is extensively
cultivated for its edible seeds and it's
oil, fever patients sleep upon beds of
sunfiower leaves and Russian physi-
clan, experimenting upon 100 children
between one month and twelve years
of age, has found that alcoholic ex-
tracts OF the leaves and flowers cure

Spain and France also the sunflower
has proven as satisfactory as qulnine
in fevers.
Alien, the new alloy of two parts
of aluminium and one of zinc, makes
very perfect and durable casts of even
the most delicate ornaments, and
proves to be adapted to many pur-
poses. 1t takes a beautiful polish.
Compared with cast iron, the alloy is
equally strong, much more elastic,
and Is greatly superior in its resist
ance to rust. The last named quality
especially entities this material to
consideration.
Ordinary unrehned helium, obtain
ed by calcining cleveite, has been
made quite pure by two French
chemists by f'tering through quartz
heated to HOO q. Helium diffuses
readily through the hot quartz, which
is impermeable to all other cages
