The discovery OF coal tar c0lors
Is the great romance OF modern sci
ence. Ages ago the gaudy flowers
and plants that grew on this hot,
moist planet decayed and. being GOV.
cred with rock, We're converted by
pressure into coal. II is only for two
centuries that man has known how
TO extract from coal the heat which
was stored up in IL during the car
boniferous age. The latent light and
color in the black diamond" needed
only the magic touch OF the syn
thetic chemist to be released. This
touch was not given until fifty years
ago. when a foreigner discovered the
secret. Now from the grimy refuse
OF coal heaps more than 400 coal tar
colors have been rescued. which are
used In the manufacture OF social

Some OF the giant railroad bridges
OF the country require hundreds and
thousands OF gallons of paint to pro-
tect them from rust and other trou.
bles coming from exposure to the at
mosphere. The reason all railroad
bridges formerly were painted red
was because for long time 1t was
believed that red paint was better
Tor structural steel than any other
kind. Then someone thought to make
exhaustive experiments and II was
demonstrated that red was no bet
ter than some other colors. II is
said that when the authorities found
that the salt air OF New York har-
Dor was eating away the bronze OF
the great Goddess of Liberty, they
decided to give the majestic lady a
dress that would protect her. and
they spent $4,000 for the drapery
OF paint with which she was clothed.
The suffragettes of the country
have abundant reason for complain
ing about the decision of a Chicago
Judge In the case OF a woman Sign
painter. A few years ago the people
going TO work one morning We're as
tonlshed to see q woman gowned in
immaculate white sitting In a trapeze
some two hundred feet above the
sidewalk, painting a hugh sign. Her
hair was flowing loosely over her
shoulders. and soon there was a per
rect MOB gazing UP at her and mar
veiing at her temerity, no less than
wondering at her invasion of this
peculiarly masculine field of endeav-
or. The police did not attempt I'd
dispense the mob. but arrested her
and had her fined. But she had sue
ceeded In advertising her wares, for
which she received a sum that made
the notoriety worth while.
The production OF mineral and
earth paints in America in 1900 was
over $4,000 tons, valued at $3l3.l33
Generally speaking. the mineral col
ors are more valuable to the painter
and the vegetable pigments to the
dyer Even skinned milk has been
called upon to furnish casein for the
manufacture of water paints. Min
eral paints are used in decorating
china, the color being burned into
the clay. Oil paints or stains are
generally used for outdoor work, but
the use OF water paints Is growing
rapidly. as they are being perfected
so as to Withstand chemical and at.
mospheric action.
