iginally crossed the country from east
to west?" asked Mr.. Patterson.
81 regard the porphyry here as one OF
the links in the chain" answered the
witness.
The witness drew marks on the $50
and 700 level maps to indicate the pres
ence of porphyry not shown on the
maps, There is still another streak of
porphyry not displayed on the maps.
The witness said that, while the char
acter of the porphyry in these bodies is
the same as all the rest, the bodies are
offshoots of the main dyke.
Mr.. Patterson asked permission of
the court to have these bodies of por-
phyry represented upon the maps as
the others are. The court granted the
request.
The porphyry bodies between the
faults were described by the witness,
and pointed out on the maps.
He outlined the body between the
faults on the 30 Michael Dewitt level.
After which he said there was small
piece showing at the west end or the
body in the west fault or beyond 1t.
He said that he thought it was boul-
der that had been dragged between the
fault walls, probably.
Mr. Hughes asked him to mark the
place on the map.
Did the country between the faults
move as far when the fauiting occurred
as that outside of them?" asked Mr..
Patterson.
No said the witness.
Can you account for that"
Yes, sir l should say that it is ac-
counted for by the fact that the move
ment occurred on the east fault plane
first and then on the west fault
plane"
The witness next described the coun-
try between the faults. He said that
the ground mass there is much shat
tered. 1t forms a channel for water
and contains punches of ore and frag-
ments of veins. AS depth is reached
the shattering lessons. All the ore
found between the faults is fragmen-
tary, and very much crushed and
broken.
1t is the belief of the witness that the
fault assures converge at both ends as
we'll as at the top. He said that if they
converge at the ends it is probable they
converge in their downward course.
In describing the faults, he said that
they are the walls Of what he would
call a north and south vein or lode,
and are composed of clay seam and
a rolled and shattered mass taken up
from the granite and the east and west
veins. There is ore. clay and granite in
the faults.
The witness said that the veins be-
tween the faults, though very shattered,
have a general east and west strike,
but are rarely continuous. They are
cut up and separated by sub-faults.
He regarded the sub-faulting and the
resulting conditions as due to the ex-
ertion of great compressive force upon
the ground.
What is the character of the granite
between the faults?" asked Mr.. Patter-
son.
IT is much softer than that outside.
1t is much decomposed and altered, and
is much harder to hold. The slopes
outside the faults remain intact and in
good condition, but those between be-
come crushed" said Mr.. Braden.
He characterized the material in the
fault assures as a brecciated conglom-
crate. He said that it is soft and
mushy in some places and cemented
and hard in others.
The country east and west of the
clay bands in the faults is hard rock
the witness said.
Several specimens from the faults
were introduced in evidence by the;wit-
ness. One of them from the west fault
showed the rolled and brecciated condi-
ton of the material In the fault crevice
Another was composed of ore, granite,
