an clcct.rlo commotion in tho attach

length, which Is radiated Into space
In nil directions, much as light is
radiated from a lamp. Part of tho
energy thus radiated'will bo" absorbed
by any othor vertical wlro upon
which it impinges and it Is Lruo this
absorbed energy which at tho ro
ooivlng end of tho transmission is
instrumental In reproducing tho

a wire which iskept elevated by means
of tho kite K. Tho cohorcr Is noth
ing more or less than a short ulass

a platinum wlro fused trough tho

platinum wires on tho insido are
8oldored a pair of pure silver plugs
which just lit tho inside of tho tube.
Tho Bllvcr plugs are separated a small
fraction of an Inch, the small space
that Intervenes being loosoly filled
with a mixturo of silver and nickel
filings. Ordinarily those filings will
not permit an electrical current to
circulate through thorn. However,
whan subjected to tho cfTect of tho

end, which Is absorbed by tho kite
wlro at tho receiving end, these
particles of metal In the coherer ap

tho galvanic battery at H is able to
