LOCATE ORE BY WIRELESS rELEeRApHY.

The triumph of wireless teegraphy in saving human lives
the wreck of the Titanic and other wrecks years.
lends vivid interest to possible application of wireless
telegraphy the Hertzan This field is imp
pecng underground and bodies Whereas the
workd of science years dcued the idea of the dv
ing rod here have scene herself setting up
fc form of DIVING rod Of her says the Mining and Tngn
|eerng World.
Briefly the principles are as follows AS is we'll known
wireless eegapy is not teegrphy at ALL for electric
rent used in transmission and moreover materials which
Twill conduct electricity will conduct the wireless Hert
zan waves and vice versa materials which used nsu
aors against electricity readily permit the wireless
pass through them.
In this difference between electricity and the Hertzan
waves lies the secret Of applying wireless to prospecting for
water or ores The Hertzan waves though often called cleo
i waves really form of light The conductors
Hertzan (which perorce conductors of cleo
ricity permit the Hertzan to pass through just
glass permits light to pass through Such conductors
are transparent translucent to Herzan waves just glass
liz transparent translucent to light Among such materials
lane aper dry sands and cays porcelain bakete ETC. On
the other hand there certain materials which opaque TO-
and will reflect the Herzan Such materials the
ucors of electricity metal plate for instance will re-
fleet the Hertzan just polished mirror Will reflect
light Supide bodies and damp strata act in this way
let us see them how wireless teegraphy may be used
There are two Instruments osator which generates and
sends out the Hertzan and coherer receiver The
waves out in all directions but metal plate inserted
the path from the ransmer to the receiver prevents any
waves being sent directly the latter Instead the are
sent in many directions into the interior of the earth They
oass through the comparatively dry layers of sand and cas
much as light passes through glass; but soon they strike
Ian exceptionally good conductor of electricity (Which is OF
course nonconductor of wireless waves such as for IN

upward through the earth and caught by the recev
no instrument or coherer The angle at which they are
aught may be deemned and by measuring this angle and
he distance between the ransmter and the receiving 1nsr
nent it may possible to determine the position and dep
# the underground ore body water zone
Such are the principles of the discovery but IN applying
hem MANY difficulties are encountered The chief OF these
difficulties is that very few strata Of sands cays or rock
lear the surface are quite dry sufficiently dry and there IS
an interference Of the free passage OF the waves

ealy sought after
The description of the principles of using wireless teegra
hy in prospecting published in Mining and Engineering
World with the hope that by calling attention to this matter
efficient number of investigators may be aroused to action
esulting perhaps in overcoming the difficulties which now
eem to lie the way of using the system Certainly the re-
wards are great. The magnetic needle has permitted the
scientists eye pierce the crust of the earth and locate GER
ain iron ore deposits too much to hope that in the near
future the wireless telegraph will enable us to find water
beneath the desert sands to locate "copper" znc LEAD
and other metaferous bodies in the heart OF the mountain
" beneath the plain?
