Professor A. Wouvermann, OF
Vienna, in examining the permanence
of watercolors, finds the most unalter-
able to be yellow ochre, terra sienna,
sepia, and various blues; carmine lakes
and the carmines generally bleach al.
most into unrecognizability
DIR. Grant Bey, distinguished
Scotchman living in Cairo, has dis
covered that the ancient Egyptians, Oh
the earliest dynasties used smokelesa
light, equal in intensity to our electric
light, for lighting their temples and
prosecuting the fine work in the inte-
rior of their dark tombs.
A skin Of very rare and remarka-
BILE bear-like animal has been brought
from the Chinese province OF kansu to
ST Petersburg by two Russian explor-
ers. Tho only other specimen is in the
Paris museum. 1t lives in Western
China at an elevation of from 10, 600 to
II, 600 feet, where it inha bits the BAN
boo thickets, and is known by the MAJ
tives as the white or spotted bear.
The South Metropolitan Gas Com
pany, of Salisbury, Eng, is conceded
to have the largest gas holder ever con-
structed, and the company is planning
to build one even larger. The one now
in use is about ESQ feet in diameter, by
1870 feet high, and will contain over
5000, 900 cubic feet of gas. The capacity
of the new holder will be about $4,000
600 cubic feet
"A new explosive, ecrasite, has been
added to the number of formida bic
agents of modern warfare. Ecrasite is
the invention of two Australian engi-
neers, named Siersch and Kubin. Its
power is stated to be in relation to dyna-
mite as 100 to 20, and the new explosive
is said to be capable of being carried
from place to place with perfect safety.
1t is not smolxeless.
DR.. Merriam, of the government eX-
petition exploring Death Valley in Cal
ifornia, says of the animal life in that
desert of horror that the scorpion
mouse lives almost wholly upon scor-
pions and like delicacies. This lively
mouse knows enough 10 keep clear of
the business end of the insect. In the
same region is found the chaparral
cock, which subsists upon scorpions,
centipedes, tarantulas, lizards and
horned toads.
There is little machine which
turns out fish hooks in six strokes.
Stroke number one bites off a morsel of
steel wire, number two makes the loop
where you fasten your line, number
three hacks the other end, number four
fattens and bends back the barb, num-
Der five makes the point, number six
bends the wire, and your fish hook
drops into little bucket ready to be
finished. Then it is either japanned-
these are the common black fish hooks
or they are tempered to the delicate
blue you sometimes see in cutlery. For
this finish, they are heated red hot and
then cooled in oil.
81 expect" said New York fisher
man to Sun reporter, that we will
get some information this year from the
Princeton college explorers who will
soon be out at sea trying to discover the
reason for the movements of the schools
of fish in the waters of the Atlantic
seaboard and the laws of the distribu-
ton of fish there. The Princeton expe-
ditions of the last two summers did
good work in this line, but they have
more work yet in finding ont how diff
ferent kinds of fish are affected by the
changes in temperature through the
Gulf stream. 1t will be q great thing
for our fishermen when all these ques-
tons are cleared up"
