THE BIG MINING CASE
The Jury Has Become Glass in
Geology.
MFARLANE'S LONG TALK
On the Stand Since Thursday Afternoon
Described the Rarus Several Times
over The Second Expert
Tells His Story.

The jury in the great mining case has
quit studying vocal music for a time
and has become a class i'm geology.
James MacFarlane, who has been on
the witness stand since Thursday after
noon was permitted to depart at 3
o'clock yesterday afternoon after hav-
ing described in detail several times
over the Rarus and Michael Dewitt
claims. The second of the experts for
the defendant then took the stand to
give his views OF the case, and gave the
jury an interesting lecture on geology
in general and the conditions of the
Rarus in particular. He will be cross
examined to-day.
At the opening of the morning session
in answer to Mr. Forbis' question Mr..
MacFarlane said that the outcroppings
and apex in the st. Lawrence Rarus
zone are well defined. He traced the
footwall of the zone on the map. show
ing that it is rather curving in form.
The witness thought the south lode of
the Mountain View should also be call
ed zone rather than a vein. It's width
is from 40 to so feet. he thought There
are three distinct ore bodies in that zone.
The material is more or less altered
granite. There are places where it might
be mined all the way across.
Mr.. MacFarlane then indicated the
hanging wall of the st. Lawrence Rarus
zone, tracing the outcroppings. He
started with an outcrop which he found
about 20 feet north of the southwest cor
ner of the Rarus. In tunnel No. |. 40
feet from the south portal, the hanging
wall is to be seen, but at no other points
of the surface. 1t is to be seen under
the surface 81 feet from the shaft of the
Pennsylvania. This is 50 feet under the
surface and projected to the surface
would be about on the line. 1t then APP
pears at the top of the Free Milling
raise. He placed the apex of the hang
ing wall at the Michael Dewitt raise.
The hanging wall runs almost straight.
The witness traced tho hanging wall
approximately along each level
} The character of the ore bodies in the
Michael Dewitt lode claim with refer
ence to the strike and dip was the next
subject inquired into. The strike is
about 60 degrees to the east and the
dip from 20 to rs degrees south. In the
Michael Dewitt ground above tie 450-
foot level is continuous streak on the
Free Milling raise. The witness sad
that since the injunction he had stored
on the Mckinley, the North Bryan ard
the South Bryan. These slopes have a
dip to the south of about 20 degrees The
South Bryan Slope is almost perpendie-
ularly under the North BRYAN. The
south from a vertical line under the
South Bryan. The South Mckinley is
about IS feet from the North Mckinley
The distance from the North Bryan
Slope to the South Bryan stope is about
60 TO 10 feet. The ore Is in well defined
ftreaks running generally east and
west. There is a continuous raise on
ore from the North Mckinley to the
North Bryan and the $50. The dip be-
tween the fault planes are from 40 de-
srees to vertical.
Can you follow on the vein all the
way in the fault?"
We can on ore. The naturalization
is greater between the planes, as | have
said, than on either side"
What Is the difference in the width
of the ore body?''
IT is five or six feet wide on the side
OF the east fault plane and 200 feet wide
between them. The smaller commercial
ore streak which we have been following
becomes much wider at the fault
And the qualification. which was
very regular. disappears, does it %
There are no well defined crexiees at
all. We have slopes one set wide and
then eight sets wide"
On what levels are the slopes be-
tween the faults?"
AT the 600. 500 and $50"
What IL the dip between the faults?"
ruTlA-Hbe 10 ~ degrees south.
What is the character of the striker" |
The strike is 20 degrees each"
1T is much further south than in |
the workings of the Michael DEWITT"
Yes
You have stopped much further north |
between the faults than the Michael |
Dewitt, have you not?
No. we have the footwall ore streak |
running clear through
But you have not stopped any fur |
ther?"
Not yet"
Is 1t commercial ore?"
Yes. all commercial ore"
But you have done no stopping fhere?" |
Not yet. but we have raise on very |
nice ore all through
Did you ever find ore between the /
