technical education. He has mined in
1 Colorado and New Mexico. and since
| 1885 in Butte. Most of his work has
been in the copper belt. He had
worked in the Grey Rock, Clark 5
| Mountain Chief and the Blue Jay: had
opened up the Ground Squirrel and
| had also examined many years He
! had spent two months ana a half in
\ examination of the country in contro-
versy. He was asked by MIR. Forbis to
go ahead and give the result of his ex-
animation. and in reply said:
THE naturalization of this district
has been so thoroughly explained that
IL is not necessary for me 10 go into
this matter. but / will say that the
| GRANTEES of Butte are very much shat
| tered which is caused by the porphy-
! ry dykes and the assure veins. So
| every 10 feet or so we find seams from
/ . to 10 inches WIDE which have no con-
| nection whatever with the veins and
are not followed as veins. These
seams have doubtless been enriched by
the oxidation of the ores above. AS a
whole. this is the greatest mineralized
district in the world. | examined the
different cross-cuts in this property to
determine the naturalization and the
thoroughness of 1t, and l also exam
ined cross-cuts in other properties and
/ find all the district scanned in this
way. Why. these seams even appear
when you dig water ditches in the
streets, and in the excavations for
cellars the seams appear I consider
the whole district mineralized, but
do not consider the entire Butte dis
trct, although mineralized, TO belong
to one man who happens TO have the
oldest location. A miner would pay
no attention whatever to these seams.
Mr. Merrill then showed samples of
rock from the mine and from other
places, including the Butte country
rock. There were samples from the
Chase raise and the north vein. The
north vein. the witness said, is one
of the cleanest cut veins in the camp.
A sample was shown from the Penn
sylyania mine. Some samples of coun-
try rock were shown, taken outside the
mine. and some of 1t taken within the
zone of the defendants outside of the
streaks. He took sample every three
feet except when he struck a streak of
ore when he would take his sample
of rock right beside it.
4 Rave had a good deal of expert
ence with faults" said Mr.. Merrill
and If | ever saw a fault there are
two faults in this mine. l do not know
how much movement there has been.
The general strike of the veins is east
and west. and the dip rather to the
south. There is no mine In the Butte
camp which has any such stopes as
those between the faults of the Rarus
mine. The dip shows there must have
been movement of some kind | have
traced the Windlass vein TO the fault
The Snohomish raise shows the dip of
the vein and follows the vein The
miners followed up the vein; it was
not done by an instrument. At the 49,
10 AVfnd1aGG Upin coming
from the Snohomish raise reaches the
fault and there strikes country rock.
The north vein strikes the fiat body of
ore between the faults and below the
fiat body is another body of ore, but
neither could be shown to be connect
ed with the north vein. On coming to
the fault both the Windlass and north
veins are cut off slick and clean. l
couldn't come through on ore. There
positively was a movement to throw
the ore body in fiat that way. | have
examined the country rock on the $50
and the $50. There have been many
drifts started on these little mites of
seams. But there is nothing there
which a miner would consider for
moment They are just seams. The
strike of the fissure veins of Butte are
all practically the same, generally east
and west. But these seams run in
every direction The Johnstown and
Powder veins have a course which
would have made them join, but for
the fault These veins have been fol-
lowed on their regular dip toward the
surface. The Mckinley. Bryan and
$50 Slopes are part of the Windlass
vein. The Windlass vein and the north
vein are separate and distinct veins"
Have you followed these Two veins
TO their apex"
Yes, each of them. | followed the
Snohomish raise to the 600 of the Ra-
rus and thence to the top or the oxy-
died ore and to the surface. | fol-
lowed up the raise on the north vein
and also the cross vein, which. how
ever. has not been developed from the
$50 level up. But it has been raised
on This vein is only a few inches
wide. while the north vein will aver
age three feet wide. The Windlass
vein at the HeinZe raise shows a vein
10 feet wide and no hanging wall.
Where do these veins come to the
surface"
ION Michael Dewitt ground. The
north and Windlass veins and the
cross vein are all under the Michael
Dewitt. No part of their apex rises to
Rarus ground. Before these raises
were put up | thought the north vein
might go up to Rarus ground. but l
now know that il doesn't. The only
thing going to the Rarus ground is
possibly what they call the footwall
VEIN
lis there a seam rising 10 Rarus
ground from the $50 cross-cut?'
Il have examined it,"
What do you say of it?s
These seams have Il different strike
and dip from the veins in the camp.
Following the fissure veins along you
must find little seams going out, some
times six by eight inches wide and /
have seen them 10 inches wide of pay
ore. but / have examined this partic-
ular seam half dozen times but IL
doesn't amount to anything. Ii starts
two or three inches wide and comes up
