The point is well made that young

something even greater than tech

An extraordinary fact in regard to
pearls is unless they are worn they
will literally pine away and die. This
is recalled by the fading at the present
moment of a magnificent pearl neck
lace in the Louvre museum in Paris,
which is described by Popular Me
chanics as being on it's deathbed. 1t
is the famous necklace left by Theirs,
the statesman It formerly belonged
to his wife and was once worth $780,
900 1t consists of 145 pearls in
three rows. The beautiful gems are
now fast losing their luster and in a
decade Or two will turn jet black and
become valueless. The authorities in
the Louvre view the matter with con-
Germ, but they are aware that little
can be done unless the decay of the
gems is arrested by their being worn
on warm human skin, SO sensitive are
they to change of temperature.

One of the most interesting of sue
Cessful airships has been constructed
by 15-years-old boy, Cromwell
Dixon of Columbus, O., who was in
spired by exhibitions at the st. Louis
exposition. With only his mothers
aid, he has in fact, designed and built
Two airships, the second a slight i'm
prCvement over the first. His mother
thought him too young to attempt to
fl, with gasoline motor, and so he
developed the idea Of foot-power ma

framework he placed silk rudder,
