GOLD SAVING AND ANAL

The amount Of gold lost in tail
ings from analgapatien mills
always enormous. Taking th
world through 1t almost passs
com pxtatisn. 1t is probable tbs
en- the whole ths amount lost ]
equal to ths amount saved b
anslganatien. The iasxpsrisncs
man, whe first discovers this fac
Immediately grasps the idea tn
less is caused by inefficient sppli
ancss, and that there is az imms
diats demand for the Invention o
a machine which will prevent th'
tremendous waste.
This is the natural conclusion
The result is there is an endless
succession Of patent placer sele
savers and patent amalgamaters
We stand on 4 limItlsss stairway
of them where the years are steps
They extend bslsw us into a past
which 10 hidden in darkness, and
beyond and sbsvs US out of sight
Ii 10 huailiatisg fact that thsss
whs are stumbling along our pres
ent step, and struggling to 80 high
er, are fer the most part wholly
ignsrant of the existence OF soant-
less millions of rains OF things
which are duplicates of those thsy
are preparing, which strsw every
step below US. They have no de
sire to learn from the experience
of stkers, but like blind men stun
BILE along over things which they
could easily see if they would.
There is nsthing new sndar the
san" isa trite sxien as applicable
to placer gold saving machines, at
least as to philosophy. Sincs the
ola xlchemisis sought the secret OF
transmutation of metals, it has
been known that gold lesses were
enormous a all placer and milling
methods. Evsy naachins, too,
which ia mads in these days to
save the losses is but duplicate
in principle, and oftsnsin ferra, OF
another mashIns whose ruins ara
found below US ON the stairway,
Some Of tkem date back to the pre-
historic days Of ths pyrlmids, and
the best Of them were ia use before
the alphabet wasinventsd. JaseA's
fleece has never bsen imprevsd
upon as aa all roand fno placer
gold saver. AS 1t was in the river
Rhine long before the coming OF
Jesus, 30 it has been used all over
the world, and is now used from
the Animas in Colorado to the
Snake in Idaho. Shaking tables
were in sss in tina days of Pliny,
and they were like the Rittlnssr
which was Sc popular thirty years
age; they involve ths same priael
pies found in our latest Gilpin
County tables.
Amalgamstion metheds, like al
most every thing else in this
world they May be classified under
three heads: First, those which
are calculated to bring gold in con-
nection with quicksilver, by dis
ssninating the pulp containing it
ever large surface ct quicksilver;
sseond, those which by grinding or
other means are Intended ts break
the costing which covers gold par
tielss, SO they ear analgamate;
third, those which use force to
bring gold in connection with a
quicksilver surface, upon the thso-
ry that force is necsssary to pre-
duss = contact, SO a1algamatien
car take place.
The ordinary stamp mill process
