this country The phOtO-lithograph printers are
also heavy consumers OF this same article. Inc
North Carolina supply OF these chrome ores is
inexbaustible. And here attention may be called
IN tbe fact that nature has stored in the heart OF

even to fullers' EARTH thai they can be entirely

Next TO iron come Goals and limestone. which are
shown in tins exhibit in wonderful variety and
abundance. The Richmond and Danvllle system
OF roads traverses a country peculiarly rich IN these
important aduucts to the iron industry and It's eX-

is that of natural coke, which is the wonder of
peology and of which vast veins exist in the Rich

Ores of gold silver copper lead and zinc are to be
seen on the benches, not in small cabinet speci
mems but in great masses that convey an idea of
the MAGNITUDE of the veins from which they

nuggets from the Dahlonega district of Georgia.
there are in a showcase solid bars valued at
81 800 and one lump from the retort worth

week said al always buy DahOnega gold when
can because it needs less refining than any other"
BY the side of the copper ores is a collection of
incots sent from the smelling works to show the
exceptional purity Of North Cardinals mines
Among the geological specimens in this collection
are asbestos ochres Of every tint. arsenic, lumber,
kaolin. uranium, rutile mica, barytes and corun-
dun. OF these it would be difficult to write such
details as each deserves without taking too much
of THR TuBUNE's valuable space. The kaolin,
uranium and rutile furnish all the essential for
making the finest pottery, for besides these there is
an abundance of slick or glass sand of fedspar of
pure tale and of lead oxides and carbonates All
the uranium formerly used obtained from the
Ural Mountains, and it is only recently that ii has
besn discovered in North Carolina. From it is OBJ

brought frou Turkey from India. and from the
Grecian Archipelago, and the importation even
now is very heavy. The product of the North
Carolina mines goes to Chester, Mass, where II is

There are also many specimens of beryl from
