ON METALS AND MINERALS
Data for Georgia and North Caro-
lima Presented.

BY r. NJ. Larner.
washington, May 20.-Director Wal
colt of the geological survey and his
able corps of assistants have been
gathering some interesting data OF
economic interest and utility to the
people Of various sections of the. coun-
try. One of their latest bulletins con-
sists of contributions TO economic
geology.
The results of Investigations made
chiefly IN 1902, are now condensed and
published 20 meet the wants of the
man Of affairs. The papers have been
grouped according to the subjects
treated, and at the end of each sec
ton is given a list of previous publ
cations on that subject by the survey
These lists will be found servlceable
TO those who wish to ascertain what
has been accomplished by the survey
in the investigation of any particular
group of mineral products. The publ
cations named in these lists can usual
" be obtained without expense on APP
plication TO the director of the survey,
except monographs geologic folios,
and Topographic maps, which, under
the law, are for sale at nominal prices.
Below are given notes on those con-
tributions affecting Georgia and North
Carolina.
Georgia
Gold and Pyrite Deposits of the
Dahlonega District" by Mr.. Edwin G.
Eckel. discusses briefly the general
geology of the Dahlonega district
Lumpkin county,, the gold ores and
ore deposits, the relations of the gold
hn
weathered zone OF gold deposits can
be worked at very low cost by hydrau-
lie mining; the deeper gold ore re-
quires expensive processes. and
chlorination has not been found entire
ly satisfactory.
The most interesting development IN
the Dahlonega district during 1902 was
the opening of a large high grade
body of pyrite near the town, the
property of the Chestatee Pyrites
Company, about six miles northeast of
Dahlonega, on the south side of Ches-
tatee river. This deposit outcrops
about 1000 feet along the surface of
the ground. 1t appears to be not less
than twenty feet in thickness, and has
been followed down on the dip for
distance of about $50 feet. The aver
age of the analysis shows about A
per cent sulphur AZ per cent. iron,
ana three per cent. copper.
Manganese Ores of the Gainesville
District. Barlow County" is brief ex-
tract by DR.. c. w. Hayes from the
descriptive text of the Gainesville geo
logic folio, now in preparation. AL
though a large amount of manganese
ore has been mined from this district
most of the work has been done in n
primitive and inefficient manner, and
it is probable that with modern ap-
planes. much material would pay for
working which does not contain enough
ore to be profitably worked by the
present methods.
Iron ores of the Gainesville dis
trict," by DR.. c. w. Hayes and Mr.. e.
c. Eckel, discusses the general geology
of the district in its relations to the ore
deposits of the region, one of the most
productive in iron ore of the Southern
Appalachians.
The iron ores mined here are specu-
lar hermatite, in somewhat limited
quantity. ranging from 55 to IS per
cent. in metallic iron and at several
pits falling within the Bessemer limit
of phosphorus and brown hematite or
limonite, in large quantity, carrying
90 to 90 per cent. metallic iron and
about l per cent. phosphorus.
Concurrence and Development of
Ocher Deposits in the Gainesville Dis
trict," by Messrs. c. w. Hayes and E.
c. Eckel, describes the occurrence of
ocher and the development of the yell
low ocher industry near Gainesville.
Four mines, with their accompanying
mills, are in active operation. and two
additional properties are well develop
ed. The process of milling and collect
ing the ocher is described.
"Fullers Earth Deposits of Florida
and Georgia, is discussion of the
Florida and Georgia deposits of the
mineral by Mr.. T. Wayland Vaughan.
Fuller's earth was first found in the
United States at Quincy, Fla, in 1898.
Since 1896 details regarding new occur
rences have annually appeared in the
volume on Mineral Resources publish
ed by the United States Geological Sur
vey. Extensive deposits occur in De-
catur county, Georgia, and in Gadsden.
Leon and Alachua counties, Florida.
North Carolina.
Iron Ore Deposits of the Cranberry
District, North Carolina Tennessee" is
an abstract from the descriptive text
by Mr. Arthur Keith of the Cranberry
Geologic Folio, just published. De-
posits of magnetic iron oxide occur
along a line passing through Cranber-
ry in a northwestern direction. They
begin near Old Fields on North Toe
river, and extend. with small inter-
walls, south Of Smoky Gap through
Cranberry and on to Shell Creek in
Tennessee. The ore has long been
worked and produces iron we'll known
for its purity. At the Cranberry
mines open cuts have been made at in
tervals over an area of 900x300 feet
and to the depth of $50 feet, with
branching tunnels running in for con-
siderable distances. The ore occurs as
lenses dipping southwest. The ore is
very free from phosphorus and sui
phur. It yields an average of AZ to A
per cent. of iron. The quantity of ore
is more or less uncertain, though the
deposit has apparently a length OF
over half a mile. Large quantities are
now in sight, and a large output is tC
be expected in the future.
Red hematite is found in this ares
on the east side of Bull Rutfin noun
tain. Little work has been done il
the development of the ore, and 1T
value and quantity are questionable
Specular hematite is found along th'
south slope, and also north and north
west of Beech Mountain. The veins ar,
smaI1 or of only moderate thickness
Brown hematite ores are abundan
on the Tennessee district.
In Tale Deposits of North Caro-
lima" Mr.. Arthur Keith states tina
there are two general sources o
North Carolina talc-the marble
group of deposits, occurring as masse
and sheets in the blue and whit
Cambrian marbles (the Cherokee mar
ble) along the Nantahala Valley. an
Nottely rivers, and the "soapstone
group, found also in quantity in tn
