raise was started from the Snohomish

I'VE erdeavored,'' said Mr. Chase
| TO follow up this Snohomish in order

| point IS feet south of the Rarus south
side line. The Windlass vein is a
wide vein, running from fve or six
| feet wide to so feet wide. II is almost
| one continuous we'll defined crack go
! ing right through the country and is
one smelling streak from the 200 down.
! In the lower levels the vein is some
times five feet wide and sometimes 10,
and has parallel streaks which are
| also part of the Windiass vein. The
central band or core or channel of ore
| is the one miners would follow. Be
low the $50 the vein is more scattered
but the main channel can always be
followed. From the $50 there is a cross
vein running from the Windass TO the
north vein. cutting through the north
vein. The north vein is two and one
half feet wide, running up all the way.
There was never any question about
following the north vein. III is the
clearest defined vein in the mine. The
stopping will average five to ten feet
wide. The raises of the defendants
run in small streaks or seams, but the
north vein is evidently as l have indi-
Gated on the model. The north vein
and the Windlass vein are separated
by So feet of country rock at the 200.
The cross-eut shows four weil-defined
veins, One well-defined vein is on the
defendants footwall, While south of
the fourth vein is nothing which
miner would call "a VEN, the country
being cracked and broken. There are
many little seams on which the de-
PENDANTS have drifted, being streaks a
few inches in width for a distance. But
the only real veins are the north vein,
the Windlass. the cross vein and one
% feet further to the south. From the
north footwall vein of their zone $50
feet to the cross vein and 240 feet to
the nearest Slopes, the ground is es-
sentially granite. with nothing in ii eX-
cept the seams.
The court at this point took the noon
recess.
At the opening of the afternoon SEES
sion Mr.. Chase was asked in regard
to the faults.
There are two distinct faults" he
said, with inclination to the west of
about As degrees. The country between
the faults is much more crushed up
and broken. AT the surface and down
for a distance of 100 feet the entire
country between the faults is crushed
and broken and stained with iron rust.
Above the point where the ore ends
ana the rock becomes oXydiZed a miner
could put a raise anywhere, and the
material would look exactly the same.
The east fault is more extensive. and
causes the most displacement There
Is more of a break than west of the
fault The fault causes a break in the
continuity of a VEIN 1T is possible in
many places To break through from
the fiat vein between the faults and
reach the ore in the straighter veins
east of the fault. But going down on
the fiat vein to the 500 there is nothing
TO be seen of the Windlass vein just
east of the fault. The veins east of
the fault are independent and entirely
different veins. At the west end of
the Michael Dewitt the defendants put
up a raise called the Free Milling
raise. which reached the fault. The
vein ended there. BY drifting east the
vein could be followed. The plaintiffs,
however made direct connection
from the Snohomish raise. The miners
came through on the vein without any
break. Above the 134-foot level the de-
PENDANTS raised on streak a few
inches wide which gave out in short
distance but the raise was continued
to the east fault. No. 3 raise also
struck the fault at the plaintiffs so
foot level"
The witness exhibited a number of
cross sections, showing various por
lions of the Michael Dewitt and the
work done in developing the veins to
the surface for the purposes of ltiga-
ton. The defendants had made a
raise from the 500 to the 100 to show
that the north and south veins con-
meet between these levels. Mr.. Chase.
however, did not believe that these
veins connect. lie thought the north
vein would on further development be-

wide for about 10 feet, and then
changes to a diagonal direction. It
crosses the north vein and then goes
up in the fault.
In regard 10 the defendants placing
the footwall where they did because
of its wetness. Mr. Chase said there is
directly above this point on the sur
face a leaky watering trough. Were
fsle trough at some other point of the
surface il makes a wetness somewhere
else in the mine. and thus places the
footwall elsewhere.
