the fault you see the veins stand up
nearly straight. The $50 slopes are
represented by green. which are the
topmost mining ore. The 600, 100 SOC
and 900 levels are almost vertically un-
der the $50. But between the faults is
vein with a great change in dip. be-
ing turned over nearly fiat. West of
the west fault is another group OF veins
which has also been marked with con-
siderable regularity. There is the
Johnstown vein, called by the defend
ants the connecting vein, which has
been stopped up to the $50 There is the
Powder vein and the South. both of
regularity and ordinary size. Still
south of the South vein has been
opened up another vein, shown by
orange strings, and still farther to the
south. another vein has been opened
up since this suit was begun, and is
shown by drab strings.
AT the $50 level. between the faults,
is another vein. The plaintiffs made a
raise to determine where the South
vein would apex. A level was run out
from the Mountain View vein third
level crosscut. which has since been
connected, showing it is on the same
vein. In the Harris and Lloyd
tunnel was disclosed a quartz
vein which subsequently proved TO
be the South vein. A winze was
started on the South vein and a raise
from the tunnel and they came to-
gether on the same vein. No instruc-
tions have been given the miners to
do anything further than follow the
vein. The Sullivan shaft was sunk
through country rock and a crosscut
run to connect the North vein. 1t was
demonstrated that the South vein,
called by the defendant the North vein
of their zone, apexes north of the
Johnstown north side line. and the
same is true of the Johnstown vein
neither of them passing through the
Johnstown end line.
In regard to the outcrop traced
from the Rarus to the Anaconda
will say that there is 20 to % feet of
slide all over the hill. The defendants
made cuts to trace the crop, but
could not detect where it passed
through any vein. AT the west end of
the Rarus is a porphyry dyke. There
is nothing to indicate to me. by ex-
aiming the surface. where the apex
would be. The only way to determine
the apex is to do as the plaintiffs have
done-raise up on vein to the apex
at the surface. The plaintiffs sunk a
shaft from the Johnstown and run a
crosscut which reached the South vein.
The South vein is entirely cut off from
the veins further to the south by 100
feet of barren rock. Further south

East of the fault are two principal
veins-the Windlass vein and the North
vein. There is also a cross vein. which
| think has little good ore. and there
is vein farther to the north which the
defendant calls the foot wall streak.
The porphyry dyke shows persstently

seen west of the fault. 1t is seen in
the Harris and Lloyd tunnel and in
most of the workings But the por-
phyry dyke east of the fault ought to
show. If 1t were not for the fault in
the same direction. / think the dyke
was once continuous. but was dislo-
Gated by this faulting. and the dyke
east Of the fault throws to the north
$50 feet. These are the indications as
they appear to me. although, of course
we cannot demonstrate ii to a GER
tainty.
The first main point at issue is
where is the top Of the Windlass vein
and the North vein. Second, whether
the veins are separate and distinct or
should be linked together into one
great zone. The term zone was applied
in the Richmond Eureka case. where
the zone was 500 or 600 feet wide"
Eight hundred feet wide" corrected
Judge Knowles.
The court will correct me-" contin-
ued Mr. Chase. THE distinguishing
feature of this zone was a bed of lime
stone, while at the footwall was a dis
tinct rock, quartzite, and at the hang
ing wall was shale. Anywhere i'm the
bed of limestone between the quartzite
and shale, the miner could find ore
The boundaries were well-defined but
the ore bodies irregular. In such
case the word zone might be substitut-
ed for the word lode. The Rarus' al
legged zone has the very opposite condi-
tions. 1t has clearly defined ore bodies
but very poorly defined boundaries, as
has been shown by the defendants
themselves. The hanging wall is dis
connected and poorly defined The north
wall is bounded by the south vein with
which it runs for time. Yet there is
no place in the mine more thoroughly
than the middle west cross
cut. The country between these veins
is no more mineralized than in this
and other crosscuts beyond the
zone At first glance one would be
struck at the amount of mineraliza ton
in the rock between the faults. ] was
surprised myself when | first went
there. But after l went To other mines
of this camp | found the mineralized
rock common feature"
Inc witness mere showed number of

The bed seams, he said. are not com
mon 10 this zone, but are to be found in
every crosscut he had ever seen. The
seams, he had concluded, have nothing
to do with the making of vein or the
making of the zone. If this Rarus mine
is called a zone then the whole country
should be called a zone. for Ii is all full
Of seams. From the Johnstown vein to
the Mountain View south vein is a
which is full of seams. So
with the Harris & Lloyd tunnel An
other erosseut running from the south
vein over 10 the Shannon vein is much
the same. The seams are all through
the country. The Shannon is over 800
feet from the Mountain View south
vein. The witness exhibited a map OF
the zone of various hues He had taken
