have a hanging wall or are only guess

ing at it?''
THE fact that the cross-cut runs out
of ore shows to me that there is no
extension of the assures to the south.
If there We're assures rurther to the
south there would doubtless be a spur
of ore running from the eross-cut still
10 the south"
That ended the cross-examination.
On redirect examination Mr.. Boehmer
was asked to measure the distance
from the south line of the Rarus zone
to the new vein of the Pennsylvania
to the south. just attached TO the model
by the plaintiffs.
1T is 40 feet" said Mr.. Boehmer.
THAT is not as big as your Rarus
zone" remarked Mr.. ForDis.
I'VE could put in there a whole zone
as big as ours of barren rock said
Mr. Vale
What is the distance" pursued Mr..
Vale. from the southernmost slopes of
the Rarus zone to this supposed Penn
sylvania zone?"
Five hundred and forty feet
From the south end cross-cut in the
300 level or what is known as the hang
ing wall streak of the Rarus zone, what
is the distance to this ven?"
1T is 335 feet
is there anything between the Rarus
zone and this Pennsylvania vein to
| show that the intervening country is
mineralized?"
No
is there anything to show that the
Intervening country is not mineralized?'
so far as the cross-cut has been
! driven the country is shown to be not
mineralized."
What distance has this cross-cut
been driven"
Il believe it has been driven so or 90
] feet now. but it only shows 90 feet on
! the model.
To further questions the witness said
that the rock of the mine is mostly
| granite with some porphyry. The por-
! phyry did not prevent or interfere with
/ the naturalization. In this mine the
/ naturalization was caused by strong
i assuring in an east and west direction
with intellacing assures as well. The
/ mineral waters came up from below
/ into these assures. filled them, ana
| gradually decomposed the granite, leav-

The formation of the vein was slow ana
| gradual in open assures. There are usu-
ally other minerals introduced into the
| assures which differ from the country
! rock and are called the gang of the rock.
/ The rock before naturalization would
| be the regular country rock. The min
! efal solutions would not as a rule be
confined to the assures, but would inn

with varying intensity. The closer the
cracks are together. the more thorough
/ ly would be the naturalization OF the
intervening rock. Within the zone the
bed seams contain copper ore but do not
! contain 1t out of the zone.
The noon recess then took place.
Mr.. Boehmer was still ON the stand
at the opening of the afternoon session
for further redirect examination. A
plane, he said could not be drawn
from the Rarus line to the Michael
Dewitt east end line without cutting ore,
nor could a meandering line be drawn
from one OF these points TO the other
without passing through ore. On re-
! cross-examination the witness said that
| the matter between the faults is mostly
decumposed granite. The two faults are
90 or 30 feet apart. and there is a second
| any naturalization between. MI Boeh-
mer was questioned more specifically
in regard to matters than any other Wit
ness and was subjected to five direct eX-
aminations and four cross examinations
When released from the stand, Mr..
Forbis said to Mr.. Vale:
Now. VIII you take the stand2'
Il will, if you call me. very willingly.
NJ f. Kennedy was called then 10

the mine.
