SO, In speaking about drawing line
along the Windlass vein to the west
1,450 feet, could you have gone, at the
time you testified, farther west at that
level than the 1,150 feet representing
these two leYels?" asked Mr.. Patterson.
mo, sir; that was the extent of the
openings then" answered Mr.. Akers.
The witness then explained that the
1,450 foot line that he spoke of was not
to be drawn on the 400 level on a hori-
zontal plane, but was meant to stretch
from the eastern extremity of the vein
on the 400 level to the western ex-
tremity of the 900 level. In the first
case, the western end of the line would
take the vein to a point midway be-
tween the faults; in the second case, the
western end of the line would take it
only up to and outside the east fault.
The value of the distinction is evident
when it is remembered that the wit
ness testified that all the east and west
veins, the Windlass included, are cut
off at the faults.
The examination of Mr.. Akers was
concluded, and Sidney w. Tyler, the
sixth expert witness for the defendant,
took the stand. Mr.. Tyler is 81 years
old and lives at Denver, he said. His
education was received at a college in
Massachusetts, and at German uni
versities. He was a student at the
Royal Academy of Mines at Freiburg,
Germany. He said he has been engaged
in mining engineering and general min
ing ever since he finished his schooling
in Germany, and has had experience in
the mines Of Mexico, New Mexico, Arr
IONA, Colorado and Montana. He came
to Butte two years ago, and began the
examination of the ground in contro-
versy in August, 1897.
The witness said that he had exam
ined the geological formations in the
ground, and he gave his opinion as to
the sequence Of their formation. He
said that the granite mass of the coun-
try was first much decomposed, kaolin-
lied and fractured. Then the porphyry
dyke was formed in it. After this, and
thirdly the east and west series OF us
sures were formed and mineralized.
The faulting of the country occurred
next, as the fourth phenomenon. Inc
fifth transformation consisted in the
oxidizing of the upper parts of the east
and west veins, which left the quartz
skeletons and caused the walls of the
veins to be pressed together near the
surface, shrinking the veins
The witness thought the primary min
eralization of the east and west assures
was produced by succession of flows
of minerals in solution, but there Is no
evidence to his mind of secondary en-
from above. The vertical extent Of the
ore bodies is too great for this, ne
thinks, and there are other reasons.
why do you say you think the por-
phyry dyke antedated the east and
west fissures?" asked Mr.. Patterson.
Because it is mineralized. The veins
cut through both 1t and the granite
said the witness.
He said that the faults came last
because they had disrupted and dis
placed the porphyry dyke and the veins
Another proof is found in the fact that
the ground up mass in the fault crew
ices contains, not only pebbles OF por-
phyry and granite, but rolled pebbles
of ore; and still another in the fact that
in places at the faults, it can be seen
that the ends of veins have been car
ried in the direction of the movement.
Il know of only one great fault in the
ground It has been called two faults
but it is one fault with two walls. 10
nv mind it resulted from one independ-
ent movement" said the witness.
He stated that he considers that the
dislocation, displacement and confusion
of the zone faulted occurred at one
time, on one plane and with one con-
yulsion of nature similar to an earth
quake: and that the faulted zone so
completely lost it's identity that he re-
CARDS the whole area as one Dig lault.
He expressed the opinion that In such
PHENOMENA, a throw of 200 or 4oO rect
in extent may occur
The witness theory of the displace-
ment as to the sections of ground affect
ed and the direction and the extent OF
the movement agreed with that of the
previous witnesses. He said he reached
his conclusions regarding this by cor
relating the veins east and west OIL the
faulted territory and the bodies of por-
phyry. ,
estate whether you were able TO cor
relate any of the ore bodies within the
inter-fault zone with any of those out
side" said Mr.. Patterson.
mo To my mind no such correlatloH
is possible" said Mr.. Tyler.
with the use of the defendants apex
man the witness was engaged in tracing
the apexes of the veins when the court
adjourned the case until 10 o'clock
Monday morning.
