employ OF a number OF mining COM
panies of Utah. Mr.. Palmer said in this
district he has examined the Rarus
and Johnstown mines. and several years
ago had examined the Alice. He spent
rs or 80 days recently in a study or the
underground workings of the Rarus.
THE main question at issue, said
Mr.. Vale, lis whether or not the slopes
in the ground are a broad zone win
apex in Rarus grounds or whether there
are a number of veins with their apices
in Michael Dewitt ground. State TO the
jury your examination of the mine and
the conclusion you reach.
II find" said Mr.. Palmer. "a zone
with,a strike east and west with dip
to the south of about 10 degrees. The
zone is 200 to 300 feet wide. There are
in IL two systems of assures which in
tersect, one coursing from the nortn-
east and southwest and the other south
east and northwest in general way.
These main assures continually inter-
sect each other and run from the hang
ing wall to the footwall of the zone.
The ore bodies are found along the foot
wall and the hanging wall at times, but
the greater part is within the body of
its zone and in the intersecting assures.
Sometimes they blend together and
the ore occupies the space of two or
three of the assures. At other times 1t
is narrow and occupies the space of
sureS are nearly vertical By means OF
these interesecting assures we can by
somewhat continuous route come all the
way through ore bodies to the hanging
wall. The greater part of the lode Is
mineralized granite. The only conc!u-
sion which can be reached considering
all the ore bodies found there and the
manner in which they are tied together
is that all belong to one and the same
zone
I'm addition to the intersecting fis-
sures nearly vertical are series of
joint planes running nearly east and
west, dipping with low angle TO the
north. They resemble somewhat the
qualification OF Sedimentary rocks
They serve to tie the ore bodies together
again as well as the intersecting fis-
sures. There is porphyry in the lode
appearing sometimes as a dyke and
sometimes as a sheet. The mineral ex-
tends through the dyke about the same
as through the granite.
THE upper part of the lode from
about $50 feet to the surface has been
oxydzed and so carries little value.
Below the $50 we get the sulphide ores.
Many of the intersecting assures are
thoroughly oxydized above the 250 and
are readily traced down to the sulphide
ore bodies. Within the zone there Is a
little iron pyrites to be found, but out
side the zone 1t is rather plentiful. This
forms one distinction between the lode
granite and the outside granite. 1t is
one of the tests. The lode granite is also
more or less altered and softened near
the surface"
Where do you find the top or apex
of the lode?"
1T crosses the west end of the Rarus
claim and the cast end of the Johns
town. The entire width is found With
| in these lines. At the east end a very
small part is found north of the south
east corner of the Jamestown"
! , lis there not, however, a break in

There are two fault planes running
/ nearly across the zone. They converge

! crushing between the fault planes, While
| below it Is more solid. The ore con-
| nection is made through this ground at
the 800 and 450 and down To the south

The witness then described in detail
and at length the various streaks and
ore bodies with their connections, the
position and character of the footwall
and hanging wall, going over the ground
taken by former experts and repeating
| and confirming their testimony. He said
| that except as affected by oxidation
there are the same ore conditions in the
upper workings as in the lower work.

MI Palmer is somewhat deaf and
Mr.. Vale had to raise his voice to a
high pitch in asking questions. When
the direct examination was concluded
Mr.. Forbis said:
II guess you had better cross-exam-

Mr.. Vale thereupon began the cross
examination of his own witness, bu

and answered, Mr.. Forbs said:

The witness said it was not unusua

How much experience have you ha
