EXPERT RAHT I[sT|F|Es..
Tells About Fissure Veins and the
Experience He Has Had
With Them.
Lawyer Mcdonnell Thought There
Were Some Barren Spots In
His Geology.
The Vein In the Drum Lunmon IL Like
Those in the Alta and
Australia.

The witnesses examined yesterday In ths
big mining case we're A. Raht. formerly OF
Montana. but now experimenting . mine
in Colorado. md Charles Goodalc, snpsrin-
tendent Of the GaRnon mine At Butte. In
giving the results OF his examination OF the
workings Of the Drum Lummon Mr.. Rsht
referred 10 the Gloster, Alta and Lexington
mines being Gomewhat similar IN their
veins. He said on his direct examination
that in many places in the Cruise level 10Th
walls can DO seen. and show very distinctly.
In answer to n question OF tho court the
witness said he thought that when u miner
talks of mineral he means ore. He did
not think any minor would call . slate with
a small seam OF quartz or calcite In it..
mineralized. He said the material dis
closed in all Of the crosscuts cast Of tho
ST. Louis incline there was hard, good
slate; some OF them showed little
quartz veins. The material between the
east and west levele. east and
west drifts OF tho thirty-foot level showed
little quartz veins aud the same sort OF
slate. In his opinion it was not vein mat
tEEs 1lo u0xu we'll w shO AAoAVAu N~e
which showed two good walls; they were 80
close together that he had to crowd side
ways in one part to get through. At the
No. 1 shaft station the Drum Lummon vein
il about ten feet wide. The witness said
he did not notice anything remarkable
about IL. At the Pixley stope the vein'is
about eight feet wide and shows a very good
foot wall. At the beginning of tho sanp-
son stope one can zee the wall very distinct
and plain, and in the Sampson chute tho
o.e Ia about sixteen or eighteen feet wide.
After passing tho Sampson stope the foot
wall appears very nice and distinct again
on the southern end'o of the Sampson Slope.
From the examination he made of the
workings the witness believed that the
average width OF the Drum Lummon vein
in the ore chutes would be about fifteen to
eighteen feet and in the barren portions IT
would not average more than three feet at
most. He thought the Drum Lummon was
n simple fissure vein. 1t was his experience
that fssure veins vary a good deal III width.
One example is at Gloster. not very far
and pinohes down to nothing. perhaps half
an inch seam. When the question came
up Of the Gloster giving out it was a plain
case. In the Attn mine the same thing can
be- seen frequently, the whole mine 10 made
up OF ore chutes. and they pinch on to
nothing, sometimes an inch OF only nalt an
inch thick for perhaps a 100 feet or 30 be-
fore thew prem out again into a new chute.
The witness said he had chasge~of the Alta
for Ave or viz wears. The Australia mine,
between the Comet and Boulder. 10 also y
good illustration. Mr.. Raht said they had
q Ralena vein there five or six feet wide,
and il rinched out to nothing but a clay
seam on which they run 300 feet and did
not fnd anything else. The witness also.
Ind some experience at Butte In the Lex-
inston nine. 1t also shows the same taper
ing out of big ore chutes INTO small places.
It ia a common thing. he sold. with refer.
enoe to fissure veins. to have parallel
cracks in the country rock with no onnec-
tion. having no vein connection with the
fssure. The witness remembered a good
example OF this in Germany. at Holzappel;
the vein is worked all the way Tor three
and a half miles. Further from 1t there 10
a vein. to be found III every crosscuh
fest away from the other vein. but IT. 10
barren; that is. there are lully three and a
hnlf miles whore both veins ore known, one
bearing ore aud the other bar en-. Between
them 10 the regular county, rock. which 10

nebanQanR. which means sioe vein;
The witness said in his opinion the Jubi-
lee, Sampson and the Jubilee No. 2 ore
chutes were on the Drum Lummon vein.
lie was examined bv Judge Mcdonnell. On
the c: discrimination som pieces OF rocks
were submitted to the witness for nm in
erection, which led to nm objection. The
court said the trial was at such a point that
tho Jury could not be treated a. experts;
they had to rely upon the testimony of tue
experts. If the jury. he aaid. had to RELY
u,on their own knowledge in regard to
mines there would not be much use In In
Producing experts; the jury would simply
nave to 60 and look at the property. The
plaintiff took an exception to the ruling. |
md the witne IS sal he thought be would
call the rock vein filling. Mr.. kaht was
asked to define what 0ouge 10. and said in
the widest sense of the term he would I'M
derstnnd it to be simply a soft streak any
where; tale may be a part OF the gouge.
Between selveQe and what the miners usu-
Ally call tale there is no difference. but the
couce NAV be a great deal widcr, and made

The witness and Judge Mcconnell hore
got into n little tilt. The judge asked Mr..
II sht if some change was not the result of
the movement of the vein walls. He re-
piled that he did not know; tha. he did not
see them move. "Well. You arc a sciantist,
are you not?" asked the judge Tho wit
ness said he WAS not. Aren't you n Qsolo-
