James McFarlane on the Stand
in the Big Mining Case.
FIRST OF THE EXPERTS
1t Took Him all Day to Describe the
Rarus Mine With the Aid of the
Model-His Cross-Exarniation

tire day and probably the best par of
another day will be consumed in his
ross-examination and further diccct
examia alton. BY means of the model
Engineer MacFarlane went all through
the Rarus mine. He showed and de-
scribed every shaft, level, tunnel drift,
raise, stope cross-cut, winZe, ore body,
fault, streak. vein, etc. He began his
description when cour. opened in the
morning and only finished when court
adjourned last evening. Most of the
testimony OF course Is unintelligible ex-
cept in connection with the model. The
witness first presented a sketch of out
crop on the Rarus claim and vicinity
to show that the st. Lawrence and
Rarus lodes are the same. He showed
by the sketch the important openings
along the zone from the st. Lawrence
TO the Rarus. The succession of quartz
streaks from two to 20 feet in width are
in zone, he said, 30 feet in width.
There are seven distinct quartz streaks
in this distance. He showed the north
connecting vein with the south lode of
the Mountain View. The various work
ngs We're described at full length and
illustrated both by the maps and the
model He showed a clay seam known
as the west fault which, however, does
not stop the ore body. Further east is
another clay streak called the east
fault which, however. does not inter-
fere with the ore seam. These are on
the 500-foot level of the Rarus. At the
west cross-cnt on the 500 the ore streak
can be followed down to the Slopes of
the 600-fo level. Further south on the
cross-cut is an ore body % or 90 feet i'll
width, which has not been developed
except by being secuted The ore
streak was followed along eastward
continuously on the 600-foot level to the
Batterman raise. This raise was start
ed on spur of the hanging wall At
the top of the raise the ore streak gives
out. Adjoining arc reached the two ore
bodies known as the North Bryan stope
and the South Bryan stope. The slopes
are a short distance south of the course
of the Rarus claim. Another cross-cut
reaches the Michael Dewitt raise called
by the defendant the Snohomish raise.
Passing westward along the ore body
on which are the North Bryan slopes,
the east fault is again passed through
The fault passes through the ore body,
cutting II. The 900-foot cross scout from
the Mountain View reaches the 100
foot level of the Rarus. There is also
connection from the 800 foot level of
the Mountain View and the 600-foo
level of the st. Lawrence. The foot
wall of the St Lawrence Rarus lode is
at the st. Lawrence. Another map was
exhibited showing the 6D0-foot level of
the St Lawrence the 100 foot drift of
foot level of the Rarus. The foot wall
streak was shown at the 600-foot level
OF the ST. Lawrence and the 800 of the
Mountain View. The drift of the 500
of the Rarns and the 45o-foot level of
the Rarus also showed the foot-wall of
the zone.
MIR. MacFarlane continued his ex-
plantations of the workings and ore bod
les in the afternoon. He showed what
is called the double shaft which begins
in the apex of the connecting or north
vein. The shaft is in the vein all the
way down TO the Harris & Lloyd tun-
mel level, The main working shaft of
the Rarus starts In the apex of the lode
and passes into the foot wall between
! the zoo and 600-foot levels. At the 400
/ cfass-cut there is still the oxidized ore.
/ the sulnhde ores being reached further
! down. At the 400-foot level are Slopes
/ on each side of the shaft going up as
/ far as the 350-foet level. On the east
! side of the main shaft an old stope is
/ passed through which also reaches up to
the 350-foot level Proceeding west ar
the 4a0-foot level a continuous ore
streak is followed which has been
stopped ON. Further west the level il
caved and cannot be passed along.

The witness expressed the opinion
that the old zone might more properi,
be described as n lode or zone than
vein. In the eastern portion Of the zon
the ore strenks are more distinctly
