Tub possibilities ol wireless are illiniitahle. By a Sydney invention the lo.ation of niincials By wireless a new era in mining possibilities opens up. A new uoi.der ray is harnessed under the iliveution and waves directed through the earth. 'I lie perfection of tli ‘•brain” system of transmission by which messages are controlled nr directed is now an «:■<nmplished tact. By exhaustive tests, it is explained by the ‘‘Sydney Kvening News”, which have been carried out in mineral and working mines in New South Wales, an instrument has been found effective in the loiatiiin of underground mineral lodes. This instrument is operated on the principle of a wireless set. Thus, by means of wireless, prospecting can lie carried i.ut at only a mere fraction of the i-nsi of shall sinking and lairing. The inventor is .Mr F. Hamilton, of West Woollahra. Sydney, who worked on the theory that radio could he applied to the direction of determining the extent of minerals. He carried out many experiments and evolved an apparatus which it is said lias been treated with startling results. Cases are said to he reported where the inventor has been able to prove the mineral sterility c.f areas, while in mines where the mother lodes have been last, .the instrument has been successful

in determining where they lie. and the extent of tV formation. The process is simply that of ordinary wireless. but instead of transmitting through the air the waves are sent through the earth. The presence of minerals is detected by means of a beam of Hertzian rays from a ray

emitter and responsive ilist i mnent.s. The railiali.r is placed in a mine, on the .surface of tile ground, or on tile side of :l hill or mountain as the case may •e. The receiver is located either underground or on the surface, in a losilir.n to receive the beam transmitted dire: l in the event of there being no intervening are body, or rellected when a bale is in between the two instruments. It. actual practice this is what happens: Where there is barren ground the receiver is energised, but where minerals inlet vene the receiver is silent. thus proving that in the imaginary line 1 between the two instruments minerals have been absorbed or rellected the electro-magnetic beam. liy readjusting the position of the receiver the actual urea of the mineral can be ascertained. .Many milling problems it i.
