courses and uDneavals, leaving tb
broken lines of the strata On eiths

clearly indicating the positions whicI
they nee occupied in remote ages
and at the same time convincing tn
geoiogist OF the great upheavaIs W icl
have taken place here.
We will observe, that If it wer,
IN our power to press bacl

that all those broken and disiointec
lines would be brought together
forming again one whole an1 continu

II would appear that prior to Ia.
upheaVal, the country, as q more OF
less horiz0nts! plane, was covered by
huge mass OF lin astone, 100 to
1000 feet in thickness. and when the
mighty suhterranean powers cxerted
themselves in their united efforts,
pressing upward, they broke and up.
| heaved the whole enormous mass O!
limestone aud formed bills, canyons,
gulches and ravinee, like those we
see at the present time, rising in SOL
emn grandeur. and towering with
their snow capped heads high up
among the clouds, with this differ.
ence. that at remote ages they ap-
peared grander still; not having IN
dergone the influence OF water and
air. Qlartz and qusrlzite are next
to limestone. the most frequent in
these districts. AL the gangue and
vein matter are highly silioious.
North OF Ophir City ale huge cliffs oil
quartz!te running southwest land
northeast. crossing .the northern
gulches and ravines across Rush VAL
ley, above and past the Quandary and
Honerine toward and pas. the Lion
No. 2 mines. Qlartzite carries the
richest ore On the Horn Silver hill
Overlying the quartzite is slate. schale
and schist, and last limestone.
Dolomite, or magnetism Limestone
appears in Ophir City as a belt ives,
OF the Chicago and b dden Treasure
rnines, and forms in Rush. Valley dis.
trict the deposit OF some of it's beat
producing mines.
Granite appears at tn head OF Eas,
Canyon and also east of Stock ton, on
the % lin divide OF the Oeuirrh
ranges. In the eastern part OF Rush
Valley district granite is NJ ore promin.
ent. Ofporphy7y there is one main belt
in each district. The Ophir belt, OF
dyke, runs from Lion Hill over
Ophir, Shoo Fly Hill and across the
eastern fank of Mahogany Hill to.
ward Rush Valley district. forming
"a dyke about 100 feet wide. This
dyke commences northwest of Silver
Shield Hill, near the Roaring Lion
mine, running northeast to the sum-
nit CT the divide, near the Sacrs-
mento mine, thence northerly
through Treasure Hill. across tie
Mono mine. thence across the east
ern flank of Mahogany Hill toward
Rush Valley district. East OF the
Mono, q branch or blowout of the
main dyke runs down the western
flank OF Skeo Fly Hill toward jacob
City.
This porpbyry appears here and
there, f-om 10 to Is feet above the
surface lin grotesque forms, spires
and pillars; at other places, as in the
vicinity Of the Sacramento mine and
in Measure Hill, it quite disappears
for some distance below the surface.
IL Rush Valley district We observe a
belt OF grabitio porphyry running in
a nortbeasterly direction, crossing in
ifs course the Ircqu1is, Silver Star,
Muscadine, Atkins, Great. Basin, First
National and other prominent mines
on st. Patrick's hill. Sobale and schist
nm in Ophir district the hanging
walls of nearly all the main lodges.
Spars of all the silicious calcite and
magnetism varieties abound every
where as ga1gue, or vein matter,
and as stalactites and stalagnoites in
caves and crevices. The great up.
heaval has produced in the Oquirrh
range q perfect anticlinal curvature
of the sedimentary beds, of which the
longitudinal axis ia north and south
erly.
About 500 or 900 feet rorth OF East
Canyon by Ophir City this anticlinal
curvature is broken through from
east to west, and shows in this break
a dislocstion or clip of the beds in
an almoet perpendicular direction,
10 an extent of from zoe
to 800 feet. North Of this
fault. the country forms g sharper
curvature than south of the same,
ehowipg in this greater upliit in the
centre, with relative and undisturbed
TANKS. On the north side deep rs-
vine cuts through the beds, following
the centre line of the upheaval and en-
ters the canyon by Ophir City. In
this ravine the qusrtzite and slatey
schist underlying the limestone is ex-
posed for a considerable distance.
This ouarlzite and slatey sehist be-
long to the lower silurian age, which
is determined by fossils found in the
shaley beds, In these fossils We re-
