Engineering and Mining JournaD
The Iron Age. that highly respect
able and reliable journal of the iron
and steel industry, printed in it's is
sue of December 3 an article by Her
man A. Holz. entitled New Process
for Locating Mineral Deposits" with
the subheadings 1.-THE Divining Rod
Made Efficient by a German Inven-
ton" Remarkable Results" Pros
pecting Revolutionized."
Mr. Holz is a maker of instruments
Of precision. such as metallurgical mi
croscopes and the like, in New York.
Therefore, we read with interest his
announcement that practical means
have been developed to a high state
of perfection for definitely locating
mineral deposits-solid, liquid, and
gaseous-in the earth from above the
ground for accurately determining
Of each deposit and for differentiat-
ing between the various materials for
ming the deposit"
Certainly there is nothing further
to be wished in these specifications
Mr. Holz further observes that 'if the
apparatus is adjusted for lead. it is
aetuated only by lead; if set for oil.
it is acted upon only by oil The ap-
paratus can be adjusted for practic-
ally all useful materials found in the
earth such as all ores. salts potash
etc.. coal. sulphur. asbestos. oil, nat
Tal gas, various clays, precious
stones. diamonds. etc). mineral wa
ter spring water. etc"
Again. there is nothing lacking in
the specifications for a complete and
reliable finder Mr.. Holz does not
mention whisky, hidden treasure, and
buried evidence of crime, but there is
no doubt whatever that this infallible
little scout would nose them out, as
capably as do the experts in those
lines whose letters to us announcing
their gifts we have from time to time
published. In these purely American
cases the gift was psychical: but the
German invention is a tangible one /
and we infer that anybody can use it /
who has the price to pay for it,
rays given off from mineral deposits |
are detachable "at distance of fifty
miles from the deposit Indicating it's
presence and general direction al
ready from such a large distance"
The writer himself has tested the in
strument and located in Germany a
arge lead zinc-silver field '"right near
he American occupied territory"
Mr.. HOlz is not at all unconscious
If the Importance of his announce
nent of this discovery which seems,
according to him. to be well known in
europe, although the enlightenment
# America as to what was going on
broad was delayed till Mr. Holz took
he steamer to return to New York
ringing us the news from the CEN
ers of civilization
1T is hardly necessary" he says "to e
well upon the tremendous value of v
his invention; it is bound to revolu- ,
Cnize mining methods" Quite so; o
Mt go on, Mr.. Holz TT will reduce g
he speculative element in mining and n
rilling operations to a minimum: it "
i'll render great help to biologists in b
lluation reports. in laying out ex- a
ntions to shafts 60. in relocating Il
re veins which have shifted in the p
nth, and in profitable exploration of b.
ineral fields consisting Of discon-
nuous ore bodies. It will increase Sc
hciency in mining all around. There n,
no more need of wildcat drilling for d,
!; the indications Of the process are cl
to a depth Of 1000 feet" Yes n,
deed: and it will do still more It DC
N revolutionize industry and the TO
story of the world incidentally put re
lg out Of business the mining geol- dl
list and the drill man. ne
Mr. Holz offered a similar manu- OF
ript to us, bnt we have hesitated to en-
biish it. We come from Missouri. Or
