THE GREAT MINING SUIT.
Eureka Consolidated versus The
Richmond Consolidated.
THE THEORY OF WATER COURSES.


SECOND DAYS TESTIMONY CONTINUED.
Characterization of w. S. Keyes, mining
expert:
| have given FL the reasons that 1 know Of
stockholder in the X X; | have considerable
contingent interest in the X *; | don't know
whe holds my stock; never got any pay for
it; | returned it where | received il, and |
am informod tina. VIII en- tho new party. takes it
J will be paid. There is a question between
tho X X and Eureka Consolidated about the
dividing line. The dip OF the Eureka
Consolidated mine is northeast; tho general
dip of the Eureka Consolidated is to tho
north to northeast; the dip of the X X is
further to the north.
[rhe tracing OF defendants map was here
introduced.]
The X X dips more to the north than the
Eureka Consolidated. Tho dip Of a lode is
always at right ang es with its course; [
don't know whore III. dip would be prof ected
to. l studied at FreIburg, in Saxony, under
a corps OF principals; | have heard Won Gotta
lecture o. geology; l tnink he is a great the
orist; | first learn my facts and then dAduce
a theory. A lode is a rift in tho earth which
has been filled with ore. | use terms ore
vein and ledge indiscriminately. A cleft or
rift may be produced in several ways. l have
no theories on the subject. The formation
on Ruby bill is Observation-Disclosures and silu-
rIan; both limestone and quartzite are meta
~morphosed: the quartzite was deposited first;
qunrt2its is massive quartz; limestone Is de-
posted from INTERNAL sebs, anu Il large pUT-
ton from the bodies of animals: first the
quartzits. then limestone, and the mineral
matter or ore deposited subsequently. |
have heard of pipe veins; they are found
principally in carboniieroas limestone;
understand a segregated vein to be one that
is set out from the country rock Witness
attention was called to p. 81 OF Won Coita's
Treatise on ores and Mineral Veins. trans
lated by Prime.l He also thought that
while Won Gotta was good authority, his
nuIUiopS ware thpOrNtIqQI rnfhpr than BFnptI-
cal. Nv observations teach me that all
veins are irregular in Formations: the car
bonic acid is responsible for the cavities IN
the limestone; | should expect to fad the
mineral d posts irreg tlar II the cavities
were Irregular; n smooth wall OF limestone,
underlaId by clay, forms the X Il wall; the
shall; is much thicker in tho Richmond, and
g. ows much smaller as you go south. In the
X X, the clay shaie IL from n few inches to a
loot in thickness; in tho Rich aond, the DRIFT
penetrated shale four feet; | don't KNOW how
clay came tn re-: the clay found is a c. ay vein
forming the northern limit Of ore vein. In the
Boil shaft tunnel the clay seam is only a few
inches in thickness; | have understood that
there is no water IN the Richmond beneath
tho 400-foot level.
The WATER Theory.
In answer to the que'tio1 by Mr.. Wren IS
t. the explanation OF tho fact that but little
water was found in the lower Workings OF the
I,lchmond mine, while tho Eureka CONSOLE

quantities, Mr.. keyes replied substantially as
fol ows:
In the first place, tho Eureka mines have
been raising more water than the Richmond,
ard tho X * more than the Eureka. Assam
ing that these mines arc all upon the same
vein or assure. it would at first sight seem un-
accountable that the deepest mine should
have the least water. If they arc connected,
tho water would naturally seek tho lowest
point along the line Of such connection. A
careful examination. however. OF the loct
peculiaTitles OF the three mines will readily
explain the apparent Anomaly. The IL IL
mines lilo directly in the course of ono of the
subordinate ~gH'ies which hasd in Prospect
Mountain, on the south, ar consequence
catches some of tho dral. ~ towards the
valley from this source. That the amount of
water is lot very much greater is due, fret,
to tho fact that the quartzite runs, at this
point. at RICH angles to the dram guilies
from the high ground on the south; anu sec
ond. to the fact that the main drainage is to-
wards tho main gulch or gulches enptyipg
into the Fish Crses Valley on the south. and
the Eureka, in Huntingdon Valley, as | think
il IL called. on the north, / remember dis
tinctly in the past stud ing over tue appa-
renily unaccOuBtabls fact that the Layton
shaft of the Eureka Consolidated, which has
within about 10 ioct of the X X shaft, and
which was considerably deeper, there was q
much greater amount OF wator IN the latter
than in the former. | learned that the Eu-
| reka Consolidated shaft had truck tho quartz
- W - I'M - aNAa
tho X X. This Tact, taken in connection with
tho north and south break in the vein, and
heretofore moro particularly described, fur
nished az once q complete and satisfactory
explanation. A second break, far towards
the west on the ground of the Eureka Con
solidatcd, and running nearly north aud
south across the vein. forms a second barrier
between the Richmond and the sources Of
tho water. Further, wherever these cross
courses are found they indicate, and up to the
| present time have proven, the existence OF a
bullying Of the ioot-sall. This bulging is
shown on the map A, by the tongue OF quartz
lite indicated in pencil mt tho sth Level. and
also at the Sd or higher level. A similar
bullying, no doubt occurs beneath tho cross
course further west, and thus we find tive
troughs or bellows in the first wa through
which the water can draw off IN the respoc-
tive claims, Euroka.C Consolidated and II h. .,
An addi ional reason why the Richmond
should find loss water is tho fact that the
quartz to foot-wall sinks away into the val
ley to the west, and whar little water may
enter the vein rom the mere surface drain
age would quietly pcrcolate alone the course
OF the ioot-wail and disappear. The Rich
mond claims arc situated on tho very brow OF
tho spur TO the northwest. and hence receives
bat very little rain or snow water from the
south.
