Ing between the brass hulls, sets ud
an clcct.rlo commotion in tho attach
ed vortical win; throughout its
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
signals. Intervening mountains or
tho curvaturo of tho oarUi havo been
found to havo but little ofTcct.
Ixow at tho receiving or St.
Johns' 'end wo havo as befurc a
ground plate O, connected by coppor
wlro to ono end of tho "coheror" (J,
tho other ond of which Is attached to
a wire which iskept elevated by means
of tho kite K. Tho cohorcr Is noth
ing more or less than a short ulass
tnbo, which lias boon hiuhly exhaust
ed or air. Electrical connection Ih
mado with the interior by means of
a platinum wlro fused trough tho
glass ono at each end. To these
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
onorgv ladlated by the transmitting
end, which Is absorbed by tho kite
wlro at tho receiving end, these
particles of metal In the coherer ap
parently .become, for tho time be
ing, welded together into a conduct
ing mass which acts much as a solid
wlro would. Wliile tho coherer is
thus under inlhieneo from tho trans
milter ai(i is thereforo a conductor,
tho galvanic battery at H is able to
send a weak current of electricity
through it and hence through the
magnet or a telegraphic rolay It.
Under these circumstances tho last
named piece of apparatus causes a
local or secondary electric circuit to
be thrown into action or rlosrd. The
gulvuulc buttery 1j is then able to
Bond a current of elecliicitv through
an ordinary Morse sounder M, which
