THE GREAT JOHNSON LODE OF QuAETz
Last week. in company with NJ. Clayton, the gentle
manly agent Of Messrs Fremont Co., claimants OF the
Marposs Grant, vsited the above lode Of quartz and
amply repaid for q twelve miles journey over
dusty road Proceeding down the road We soon OPP
posite the famous Mount Ophr mine swhose abandoned
III and vacated buildings afford melancholy record Of
failure In quartz operations the result OF bad
management or reckless haste Where once al was STIR
and il Is only regretted that the $3.50 900 fooshy
absuraly squandered by the agents OF the Nuevo
county Leaving Mount Ophh, we followed the road lead
ing Bear Valley and soon came In sight OF huge mass
trees growing between perpendicular layers Of the
projecting lode usually known BY the name Of the John
son vein.
Is nearly due norh south, with thickness varying
from ten TO sixty feet The base or bed rock OF the val
lev is Of eot tale slate formation, which has become
decomposed by the action Of the elements the tine dust
into which II dssoves being blown OIL by the apr ng
winds or foaed away spring rains. The fact that
tie valley has been formed by the wearing away the
bed rock, is clearly demonstrated blythe projecting
boulders of the great lode which here rise up 10 nat
thick thirty feet above the surface OF the
slate. while oil around for distance Of thirty or forty
yards lie detached slabs OF rotten quartz
soon reached ds the Ssa notorious e. and
TIT turning to the left suddenly came in WOW OF
prsy,ogs to again Commencing operations This mill
has nine stamps is driven by twenty horse power
erginc, and when IN order Is capable OF crushing eight
the southern ridge OF hills that encose the valley and
the waters the various gulches aud ravines
which In winter, with great Tapdity and c0nsdera
bic voun During the summer months the creek goes
nearly dry and but few miners work along its banks
Following up the valley to the road made along
the mountain by the Nuevo Monde Company, English
company who leased this lode OF quartz from the Aerced
Mining Company. The hill through which the vein
pssses bee unneiied at six differ emit points and tho
vein cut in many places, shows thickness In one
part Of sixty feet Parts OF this monster lode
designated the Josephine and Pine free leads and the
rck, taken masse, Is uneqused in richness, aud the
vn aSen as whole uns nrpassed IN width and length
by am lead within the limits OF the state.
Some idea may be formed OF the extent aud richness
Of this NINE when II is considered that there Is sufficient
amount OF rock lying the surface OF the ground
supply twenty mills for I've years supposing each and
every of the mills to crush at the rate OF 100 tons
per day and when the TACT added 10 this that the
rock according the made from the crushing
Of three tour hundred tons Of the same will average
sixty dollars per ton can scarcely fail to Impress the
reader iih idea Of its vast mineral wealth. One
ton Of the quartz tax from this ledge

follow ing are the from the same after being
duced and the metal extracted
The gross yield OF the quartz was not given with the re-
