broken and crushed. qualification
exists there. If in some isolated places
there Is found evidence of disturbance,
that disturbances has not been suti-
Gent to affect the qualification. The
broken, crushed aud assured condt-
ton of the limestone gives 1t a specific,
Individual character. by which 1t can
be identified and separated from all
other limestone in the vicinity.
In this zone Of limestone numerous
v or chambers are found, further
distinguishing it from the neighborin2
rock. The limestone being broken
and crushed up AS stated, the water
from above readily penetrated into it.
and operating as a solvent, formed
these caves aud chambers. No similar
cavities are found in the rock beyond
the sha'e, its hard and unbroken char
acter not permitting. o II at least oppos-
ing such action from the water above.
Oxide Of iron Is also found In numer-
Gus plaC es, throughout the zone, Civ
ing to the miner assurance n a b
metal he seeks is in its vicinity.
This broken, crushed and fissured
condition Of the limestone, the pres
ence of the oxides Of iron. the caves or
chambers we have mentioned. with
the wall of quartzite and seam OF clay
bounding IL, give to the zona. in the
ewes Of the practical miner, an iDdIvidu-
atty, a oneness ~ complete as that
which the most perfect lode In u geolo-
gical sense ever possessed. Each OF
the characteristics named. though pro
duced at a different period from the
others, was undoubtedly caused by
the same forces operating ut the same
time upon the whole body of the lime
Throughout this zone of limestone,
as we have already stated, mineral Is
found in the assures Of the
rock. According to the opinions of all
the scientific men who have been ex
amined, this mineral was brought up
in solution from the depths OF the
earth below, and would therefore nat
uraily be very irreRularly deposited
In the assures OF the crushed matter,
As these assures are in every variety
of form and size, and would also find
its way in minute particles in the
loose n'aierial OF the rock. The evil
dence shows that il Is sufficiently DIFF
fused to justify giving tn the limestone
the general desig nation Of mineraliZsd
matter-metal bearing rock. The
three scien'ti e experts produced 10y the
plaintiff, Mr.. Keye-, Mr.. Raymond
and MIR. Hunt. all OF them of large ex.
perience and extensive attainments,
and two of them of national reputa-
lion, have given 1t a. their opinion
after examining the ground, hat the
Of Limestone between the quartz
tie and shale constitute one vein or lode,
in the sense in which those terms are
used by miners. Mr.. Reyes. who for
years was Superintendent of the mine
of tho plaintIff, concludes q minute
of the character and devel-
opnients of the ground, hy stating that
in his judgement, according TO tho cus
tumS of miners in this country AMI
common ense, the whole of that space
he considered and accepted as
lead, lode, or ledge OF metal bearing
earth, or rock in place.
DR.. Raymond, after giving a like ex-
tended acconn of the character OF the
ground, and his opinion a. to the
causes of its formation. and stating
with great minuleness the observations
he had made, concludes by announc'
ing a. his Judgment, after carefully
weighing all that he bad seen, Chat the
deposit between the quartzite and Shale
Is 10 be considered AS a single vein in
the sense Of tie word in which il is
used by miRers-that il, as q single
ore deposit of Identical origin, age and
character throughout.
DIR. Hunt, after stating the result of
his examination OF the ground and his
theory as To the formation OF the mine,
gives his judgment as follows:
"My conclusion Is this: That this
whole mass of rock Is impregnated
with ore; that although ths great Mass
of ore stretches tor a long distance
above horizontally and along An in
cline down the foot wall, a. | have
traced it, from this deposit you can
also trace the ore into a succession of
great IA viiies or bonanzas lying irrtg-
ularly across the limestone, and into
smaller caverns or ciiasins OF the same
sort; and that the whole mass of the
limestone is irregularly impregnate,l
with the ore. use the word iuiprex-
nation in the sense that it has p-netrAt-
ed here aud there: little patches and
stains, Ore.vugs and caverns and
spaces of all sizes and all shapes, ir.
regularly disseminated through the
mass. = y i conclude, therefore,
that this great mass of ore is, in the
proper sense of the word. a great lode
or a great vein, in the sense in which
the word is used by miners; and that
practically the only way of utilizing
this deposit, il to treat the whole of 1t
as one great ore bearing lode or mass
of rock"
This conclusion as to the zone con.
shutting one lode CT rock bearing met.
al, it is true, is not not adopted by the
men of science produced a. witnesses
by the defendant, the Rich mond Com.
pany. Thess latter gentlemen, like
the others, have had = large expert
ence in the examination o
mines, and some of them have &C
CURED a national reputation for theil
scientific attainments. No one ques'
tons their learning or ability, or the
sincerity with which they have ex.
pressed their convictions. They agree
with the plaintiffs witnesses as to the
existence Of the mineralized zone o.
limestone with an underlying quartz
ite and an everything shale; a. to the
broken and crushed condition of the
limestone. ami substantially as To the
origin OF the metal and It's deposition
in the rock. In nearly all other re-.
spects they disagree. In their judg.
ment the zone of limestone has no
features ola lode. 1t has no continuous
