LOCATING MINERALS
By USE OF #" RAYS

Counsel L. J Keena, of Florence,
Italy, writes as follows in the daily
consular report, concerning means
of exploding powder, or locating min
rails by means of "F' rays:
The experiments made in France in
August last and in Italy during the
past few months by the Florence in
ventor, Ing Ulivi, in regard to the So
called "F'' rays, have been duly
chronicled only in the newspapers. A
field apparatus which can locate and
explode a magazine or mine at con-
siderable distances is conceded to
have high value as a weapon of war,
and that proably is the primary value
of the discovery. However, the in
ventor has stated that the greatest
value of his invention ultimately will
be found in a purely commercial field,
namely. the location of mineral de-
posits in the earth.
Inventor Tells Secret.
The secret of the apparatus lies, of
course, with the inventor, but he has
given the following general informa-
tion in regard to the operation of the
F-rays: The apparatus as used by
Ulivi is equipped with resonators.
The Frays directed or aimed by the
apparatus cause the recOnators to
sound tones which vary in accordance
with the body through which the rays
pass. In his experiments in setting
off explosives by means of the F-rays,
Ulivi. has specialized on the note or
tone given out by the apparatus when
the rays encounter the explosive and
its container. The sounding of that
note gives him the accurate direction,
after which the rays are intensified
or focused, so to speak, until the ex-
plosion occurs. Parenthetically it
might be added that the F-rays under
the Ulivi system are valueless against
explosives which cannot be fired by
ignition.
Varying Effect of Metals on
Reeonators.
Tn the course of these experiments
Ulivi has discovered that the various
metals encountered by the rays each
has distinctive tone on the resonat-
ors, which tone varies in accordance
with the character, volume and densi'
tv of the body of metal encountered.
The inventor believes an apparatus
of the type now used bv him, per-
fected with a view to accurately clas-
sifiying different metals and their
volume, could be employed with eer-
tainty in the exploration of mineral
lands and in locating ore-bearing
lodges. At present Ulivi is entirely
occupied with the military and naval
value of his invention, and it is i'm
possible for him to give any attention
to the purely commercial possibilities
OF his discovery, but it has been sug-
gested to him through this office that
for an apparatus capable of discover
ing mineral in land and of approxi-
mating the mineral bearing value
thereof, a market might be found
readily in the United States.
To Develop Apparatus.
From the general description given
by Ulivi of his apparatus, it does moi
appear that the type used for locat
ing metal would be essentially differ
ent from the type used for war pur
poses. In that case, in the event OF
Uhvi selling the secret of his discov
cry to some government, the CONNER
ella value of his discovery would b'
lost temporarily. In ease the appa
ratus for locating metals is RADICAL,
different, or in the event of Uhvi Z
failure to demonstrate satisfactoril,
its value in war, he will at the ear
liest opportunity turn his attention
to the development of specialized
apparatus for mineral exploration
