NOT yet is the lightning tamed. But the
hand of science reaches forth. Already a
way has been found to make the lightning
write its own record of this destructive force
measured in millions of horsepower, which
is still the greatest enemy of high-voltage
transmission lines.
One such record is reproduced on this page.
It was taken on the lines of the Pennsylvania
Power and Light System by a cathode-ray
oscillograph-a high-speed camera developed
in the General Electric laboratories. The
surge that was recorded measured 2,500,000
volts; the record showed that the lightning
lasted 40 millionths of a second. From such
data and measurements ultimately comes con-
trol of natural forces.
There are unlimited opportunities such as
this for fundamental research in the applica-
tion of electricity. Literally beyond price is
its ultimate value to the electrical industry
and to the public. Here is a challenge to stir
the imagination of any engineer.
Back of every product bearing the G-E monogram,
from an electric locomotive to the tiny motor that runs
a sewing machine, is the basic scientific research for
which the General Electric laboratories are famous.
Both in the home and in industry this monogram
       carries the same assurance of electrical correctness and   The specialfield
laboratory which was
       dependability.                                         used for the
epoch-making experiment
