the Best.

In the Mines and Mining Building at
the Worlds Fair, New jerseys Geologi-
Cal display has made q credItabIc exhlb ii.
The State exhibits. first. minerals OF
economic Importance. beginning With the
oldest geological formations and samples
from thirty-two working mines in the
State. The ores ara all magnetic i'd. and
are from IS to 65 per cent. metal. making
a first class showing. The samples ex-
hibited are of small size. therefore they
do not attract rs mucl attention as IT
they were larger. LII 1892 the State pro-
ducsd 552.0 0 tons of magnetic ore. In
Importance for its geological formations
next comes tho zine ores of Sussex
county. Franklin Furnaces and Sterling
Hill These zinc ores ara unique In them
selves, nothing Of the kind being found
any where else Ia the world. The ores
consist OF three mfnerats-green ~sillcats
Of zinc, innate or red odids OF ziuc and
Irankiinlte or tclpls oxide OF iron, Zinc
and manganese.
The deposit at Mine Hill is one OF the
largest knosn mineral deposits in ths
world. Along les length it has besn pros.
pacted for q distance of 1000 feet, and at
this distance. 1000 feet from the frst out
crop, y diamond drill shoved a core OF
'thirty-stx feet OF solid ore. The bend ut
this point covers 1000 feet In width. AT
the present time four cam Yauies ope rate
the mlnes-the Passaic Iinc Com amy,
New Jersey Zinc aud Iron Company, both
at Sterling Hill; the Lehign Iron and Zinc
Company and the Sterling Irou and ENC
Company at franklin Furnace.
Tho annual output of these mines
amount TO 77.000 tons Of zinc ore.
Another product exhibited as coming
from the New Jersey mines lies in the
nature OF graphite or black leat. Ex-
tepsive deposits of this mineral can be
found in the older rocks of the state, bat
it Is worked at only ons piaee-Blooming-
dale.
COLLECTION OF cLAYs.
Coming 10 the more recent formations.
the state exhibits q fine collection of the
clays from South Jersey. These ciays
are 10 very extensive deposits along tue
karitan River. south Of New Brunswick
to The Raritan Bay, and. In fact. lie along
The whole Atlantic coast line TO the Della
ware River and bay.
The uses made Of these clays are OF tn
first importance. The fire brick ma d 9
from the fire clnys are among the most
refractory made aud have a wids use,
Among the clays eau also be found higI
grades OF paper clays. used for siziug
and weighing paper; clays for the MAUI
facture Of the finest chiusware, stons
ciays Tor the manufacturs of the chea per
grades OF pottery. \ great variety of the
nnOse lctla cutta cldys auu Also cue clayS
Tor the manufacture of pressed brick aud
other cheaper varieties of brick.
Another product. which, though not ex.
peusive, occurs In the State In great abuu-
dance aud proves to be a source of libsral
rsvenue. consists OF the glass sands, fire
snnds aud moulding sandss Iu the south
ern part OF New Jersey are green sand
marls and she'll marts.
building stones OF the State are also
shown. Among these should be noted
the beautiful brown-stone or free-store
from the quarries at Newark, HaIedou.
Paterson aud Little FALL, aud from the
extensive quarries on the Delaware river,
reaching from Trenton mp to Milford.
THOMAS LANES MINERALS.
From the older crystalline rocks are
specimens OF granite. gueiss aud marble.

The whole exhibit presents a comrlsts
ana artistic appearance, mucn Of which
Is due to the efforts or Frank P. Kssou of
New Brunswick. Besides the exhibit
