BUI1E'S COUNTRY ROCK

Rossiter w. Raymond, Phi. D.. M. E.,
was one of the witnesses for the defend
ant to-day in the trial of the suit of the
! Parrot Co. VS.. Anaconda Co,
which was sumed before Judge
Knowles in the United States court.
DR.. Raymond stated that he was a resi-
dent of New York and a mining engi-
neer by profession. He had been en-
gagged in the practice of the profession
i for 81 years. He had prepared himself
at the Polytechnic Institute in Brooklyn.
N. Y, and at the college of Heidelburg.
Freiberg and Munich in Germany. In
! 1861, he returned to the United States,
! served in the army for a short time and
in 1868 again began the practice of his
n,ofession. From 1868 to 1876 he was
United States commissioner OF mining TOE
! the western states and in that capacity
had visited nearly all of the mining
camps in the west. From his observa-
tons he had compiled a volume when
had been published later. Since 1866 he
said, he had been a special .contrlbutof
to the Engineering and Mining journal
and in 1871, was the lecturer on ore de-
posits at Lafayette college, Philadelphia.
II, 1871 he was also the acting president
of the Society of Mining Engineers n
had edited several volumes OF the trans"
actions of the body.
Dr.. RAYMOND said that he had made
several visits to Butte in connection with
the present suit between the Coiusa-Far-
rot and Anaconda. He had devoted
about 60 days time to the undergfouno
study of the mines in litigation. Asked
! to state what geological and minerolOgl-
) cal conditions he had found, he said that
} without going into any scientific distinc-
/ TONS, he would simply state that the
/ Butte granite was a pasalt granite with
! less silica in it than other granite, n
) therefore less liable to decomposition. 1t
/ carried what was called an original py-
I rites. Hornblende, he said was the first
I basis of this granite. The country rock
) was pyritous granite and he considered
J that that fact had an important bearing
/ on the case at issue. This field he said
I was largely a assure, cracked in all di-
I rections, and carrying a system of east
! and west seams or fractures. HI said
, he used the word system in a geological
! sense, meaning a set of parallel assures
/ not too wide apart that were independ-
! ent of each other. %
} The system of east and west fisures a
I been produced by a north and south
! thrust. Some of them had been MINER
allied by. the copper bearing solution
! passing through the small cracks and
1 of assures which might be termed sep
! arate assures with defined walls. n
5 of these assures was the Anaconda which
} could be traced for a long distance east

/ tended description of the Anaconda vein
I he would merely say that it was a re-
; placement vein, in which the little seams
had been first mineralized and them came
ular structure. That this theory was
! correct was amplified by the granite
: horse in the Anaconda vein.
! DR.. Raymond here entered upon
: as applied to mining. The term. he said,
: was not known in German mining which
= was the largest literature in existence.
4 The Germans speak of barren bodies. The
word, he said. was originally used by the
Cornish miners and was formerly called
a horseback" 1t aid not always i'm
ply a lean body, however, as one could
have a horse of ore. 1t is generally call
ed a horse until it becomes so wild tina,
1T entirely separated from the vein In
which it occurs. In the case OF the Ana
conda, the north and south vein had an
aIex on the surface SO that there could
be no disputeo on that point, proving con-
clusively that the north and south veins
We're one.
This horse. he said, is full of seams and
the processes OF nature can be seen all
through it. Relative to it's continuity,
ne said, it was clearly shown from the
the east to a long distance horizontally,
The witness said he had seen it apex un-
der the fault. The vein was an unbrok-
Ell one from top to bottom.
The Colusa-Parrot he said. was an
other vein not traceable to the east of the
fault. but continuous for a long distance
to the west and like the Anaconda con-
tinnous from top to bottom. In it's up
the Anaconda. The difference, low.
ever, disappeared at the lower levels
which contained magnificent masses OF
supplies.
Referring to the blue or fault vein the
witness said that he would present proof.
OF its existence and then state it's struc.
ture, age and relation to this case. TIL
existence of this vein had been shown
in IL places in the Anaconda working,
where the Anaconda vein itself Is seer
to be squarely and sharply cut of. TIL,
COlusa-Parrot he said. was also cut of
by this blue vein. This had been dem,
onstrated in Al crOsscuts in both the Ana
ccnda and Colusa- Parrot.
AS to the structure and gangue of tn,
blue bein, the witness said its structur,
differed from the other veins. This faul
was the result Of slow action not a VIC
lent upheaval. The vein showed a tear
ing rupture across the country which
he had traced from the Nipper to tn
Salisbury. 1t was characteristicall
1 provided with masses of clay n round
= ed masses of ore which were designate,
as drag. There was a general prevail
ence in it of zinc-manganese and arsens
! cal ~sulphides. There was greater oppOr
tunity to examine the blue vein, he said
because there were more openings on II
while In the Anaconda the most Of th
" ore body had been stopped out on the up
per levels.
