Day before yesterday we saw In OPP
Grafton at the Mexican mill on the
Carson river, a ,ailings concentration,
which performs Its work so sfisctually
that we feel justified In calling tho at
tention OF our readers to the same.
The machine was invented by Mr..
Hooper VI New York, and was first
used at Ticondsrosa In separating
plumbago from the associated ganguc
In which Il 10 found.
THIS machine II known and patented
rs a "sllms machine" Il has been
running continuously at Ticondersga
since 1871, with great success, and
separates the plumbago from the asso-
ciated ganguo so completely that the
plumbago Is sold daily as q lubricator
for all serts OF machinery at 81 per
pound. Msssrs. wetmers & Co., mer-
chants OF New York, saw the APP
preaching success Of thls Invention.
and kindly lent Hooper their aid to
perfect IL to the largest possible meas
ure, which has been done. and today

It IL we'll known by the people Of
Gold Hill, Virginia and vicinity that
there are millions Of tons Of tailings In
this vicinity containing from Is to $40
per ton and fifteen hundred tons made
daily by our mills, all OF which arc
utterly worthless without some sue
cessful method OF concentration. This
machine promises to be that method.
As matters stand. the mill men have
neither market nor method for their
taillng,. This machine promises TO
give both. All former attempts at
working tailings without concentra-
ton have failed, and Injured many Of
our best aud most entsrpri,ing citi-
zens. Several Of our leading taillngs
men have visited Empire City
to see the working OF the machine

Of dollars TO be- recovered. we trast,
therefor, that u people will give u
thorough trial aud test its verify and
value fully. The machine consists OF
n revolving, endless, india-rubber belt,
81 feet long by 1 feet wide, divided
lengthwise Into scctions, oy ruOoer

belt. This belt u placed on n wood
franc about IL feet LONG, D feet wide
aud Z feet high, aud revolves around
two cylinders, u nc each end OF
tlis frame, on an incline OF about eight
| degrees from the horizontal, and moves
BY ratchet motion from foot to head OF
the machine, the head being the apex
OF the Incline. The tailings are deliv-
cred from the mill into n dolly tub sus.
pended over the center OF the belt, aud
thence through faucets on to the sever
al subdivisions Of the belt. Over the
| head OF the belt is suspended 4 box.
