The Anaconda standard. [volume] (Anaconda, Mont.) 1889-1970, 1899-10-18

slides We're made came from Rarus
mine ore bin, and the court ordered
the evidence concerning the slides to be
stricken out, on the ground that there
was no knowledge possessed OF Where
the sample originally came from.
| The witness said that the altered por
phyry or indurated clay from the fault
crevices is found in different stages Of
| decomposition. He said that the two
| kinds noted by Mr.. King are exposed ir
the same place on the 21O level, but
are not connected at all.
Mr.. Tower was closely examined as tx
| the fault matter. He called the matter
| In the fault crevice an eruptive brec-
| cha of porphyry. He read an excerpt
from a geological work describing erup-
tive breccias. The excerpt said that a
crust forms on molten lava streams by
chilling.
'Mr. Tower, do you think that the
author meant what he said about the
| crust OF a lava stream to apply to a
sheet of eruptive porphyry injected into
| a assure, as to its cooling against the
sides of the fissure?" asked Mr.. Pat
terson.
Il do not see why he should not
said the witness.
How do you determine that this por-
phyry Is brecciated?"
We find rounded and broken frag-
ments of porphyry in the porphyry, and
also fragments of other formations"
In your examination in chief you
said it was injected porphyry. Do you
call 1t brecciated porphyry now?''
Il think it was somewhat brecciated
in the flow
But do you call it solid porphyry
II call it solid porphyry.'
Mr.. Patterson began to investigate
the color of this substance, when Mr..
Cotter interposed an objection, and the
court cut the examination off, Judge
Clancy said that there had been great
deal of evidence about porphyry brec-
cha some days before. Mr.. Patterson
interposed that the substance had been
indurated mud then, and Mr.. Cotter re-
piled that it was one and the same
thing.
well. on the dead" said the court,
Il don't know what it is vet, but I'm
getting mighty tired of indurated mud.
and l guess We'll pass on to something
else"
The witness said that there is vein
inside one of the faults, running along
with the fault walls, and that ne
thought it was formed by the mineral
solutions in the east and west veins
splling into the fault. Some large sam
pies called rounded attrtion ore by Mr..
King, were taken from this formation
by the witness.
why didn't you bring us some other
specimens than those rounded boulders
of ore?" asked Mr.. Patterson.
Because the roundness Of these
boulders does not bother me-" said the
witness
"Oh, I did not suppose the roundneas
bothered you at ALL" said Mr.. Patter-
son.
well, these samples were as good
as any" said Mr.. Tower.
Mr.. Patterson submitted a number
of samples, used in previous evidence,
to the witness and had him examine
them and tell what they were and
where they came from. The witness
said that some black rock material that
he had got from a certain point was
secondary ore and that there is an enor-
nous amount of it in the mine. The
bulk of it is associated intimately VITA
granite, but there is much vein quartz
associated with it also, he said.
The witness was cross-questioned ON
the subject of the microscopic slides
which Mr.. King had had made and
called indurated clay and which the
witness called altered porphyry
DO you call these slides simply por-
phyry?" said Mr.. Patterson.
Il call them simply altered por-
