Tho rapid strides today In the flsld OF

astlng than the story of electric lighting
itself. Sir Humphrey Davy, Of London.
was the first 20 experiment In electric
lighting with any definite object In view.
In 1909 he demonstrated the first crude
light He constructed n battery Of 1000
cells to tho terminals OF which he attached
pieces OF charcoal When these crude car
bona were brought near to each other
bright spark was produced and more than
half the volume OF the charcoal became ig-
nited TO whiteness. and by withdrawing the
points from each other n constant dis
charge took place through tho heated air.

'FATHER OF ARC LIGHTING"
~ T. Gramme. Belgian inventor living
IN Paris, In 1870 obtained his first patent
cn dynamo electric machines and exhibited
Ills work 10 the Academy OF Sciences In
1871. He Is credited with being the father
OF the modern arc lighting. although arc
lighting had been accomplished by older
machines before the day OF Gramme.

1867 by doing away with tho permanent

= soft iron core Prof Moses O. Farmer
an American inventor living In Salem,
Mass, obtained the same results In 1866
EARLY electric lighting was accomplished
~ direct current, as alternating current did
not come into use until score OF years
later Lighthouses In the Straits OF Dover
were equipped with arc lights In 1853 and
1852. and similar work was accomplished
IN France In tho latter year.
"Jayiochkoff in 1875 patented n simple
mechanism which considerably advanced
arc lighting His invention consisted OF
two vertical sticks OF carbon separated
slightly by an insulating material which
was consumed at the same time as the car
bonA These lamps soon were lighting the
streets here and abroad.
ADVANCE IN LIGHTING ART
"a short time later Charles r. Brush and
Edward Weston developed methods OF Sc.
ries arc lighting and their systems were
seen in general use. The first series Brush
arc lamps were erected In the public square
of Cleveland o., In 1879 In the same year
tho first central station operating arc lamps
was installed by the California Electric
Light Company. OF San Francisco.
