AN invention which all railroad trav-
elers will appreciate is to be tester On
the new trains of the Berlin-Zossen ex-
detrimental railway. 1t is a device Tor
carving the smoke from the locomo-
tive to the rear end of the train
through a closed conduit running along
the top Of the carriages.
The inertia Of q two thousand-pound
automobile at seventy-fve miles an
hour is calculated by e. Hospitalier to
be the same as would be given by fall
of 1856 feet. The retarding power DE-
yeloped by the brakes on the fraii tires
must average about sixty-horse power,
though the maximum strain may De
nearly twice as great. rr
Casks Of corkwood, the recent inven-
ton Of resident Of Algeria, are claim
ed to have important advantages. Cork
being bad conductor Of heat, liquids
are protected from freezing ON expos
ure to cold, and perishable substances
are preserved from heat in warm Gil
mates. AS interior coating keeps the
contents from contact with the CORK
The slaves do not warp, and an eleven
gallon cask weighed only thirty pounds
instead of the eighty pounds that
would have been its weight in ordi-
nary wood.
Investigation about year ago show"
ed that the balata tree grows in album
dance along thousands of miles OF the
Amazon and its tributaries, but that
the Brazilians were rapidly cutting the
trees for firewood and building mate
rial. Since then the production Of gutta
percha from this source has been be-
gun. Each tree yields an average Of
31a pounds, and a competent bleeder
can prepare forty to fifty pounds per
day, one mans work producing as
much sap as twenty men can get from
rubber trees. The gum Is ready for
shipment after being fermented and
then dried.
One Of the so-called lost arts ap-
pears to have been rediscovered, par
TALLY, at least, by Louis Kauf1ieId Of
Matthews, Ind. 1t Is process Of max
ing glass Of extraordinary toughness,
so that 1t will Withstand rough usage
and violent changes of temperature
without breaking. The composition OF
the new glass Is the secret of the In
ventor. The product Is said to be
quite as transparent as ordinary glass
and perhaps even a little clearer. Tests
that prove the surprising toughneaS
of this glass are: Boiling water in a
lamp chimney made of it, and using
such a chimney to drive nails. IT the
chimney is first cooled in Ice water and
then suddenly held in a fame it does
not crack.
Prof. G. Frederick Wright, who re
Gently made q trip across Asia for sci
entific study, says one of the surprises
of Siberia Is It's abundance Of public
museums in which special attention Is
devoted to anthropology. Since Asia
has been regarded by many as the orig
inal cradle of mankind, this preference
for anthropolOgical study IS particular
" interesting Prof Wright mentions
dozen cities Of Asiatic Russia, in
Guiding Vladivostok, Irkutsk, Minus
insk, TOmsk, Tashkend and Titiis
which contain excellent museums, ant
he says there is scarcely town of 10.
900 Inhabitants in all Siberia which il
not thus provided with an educationa
factor, bearing particularly on th'
study Of the human race, which may
we'll provoke our emulation.
