phuret of iron and copper. Two tests
wore made by roasting this mundic
rock, simply for iron and sulphur. A
pile of the mundic from near tho sur
face was roasted with wood, and piece
Of the drill core at n depth Of 10 feet,
was heated in the laboratory, with the
following results:

Quantity to be obtained for this purpose
IL simply incalculablc., Another ''i'lue
Billy factory can be started III this
country. 1t is hard to conceive the effect
upon the iron industries of Virginia. in
consequence of the opening up of these
ores. AS the writer has had occasion to
remark elsewhere. it is possible, by
varying the mixtures in the furnaces. TO
produce every grade of iron. As far as
known, this is tho first red short ore
that has, to this date, been made avail
able in the South.
1t can be used by itself, or mixed with
the brown ores OF the district in close
proximity, to produce Il rank or milded-
short, neutral or slightly cold short iron.
while certain of the brown ores will give
rank. cold short iron. For castings,
especially small ones for shelf hardware
etc. low priced iron can he made as
fluid as water, and of very great
strength It's great point of value is
that by admiXturc it will permit the
use of hundreds of thousands of tons of
the mountain brown ores capable of
being chcaply mined and handled. that
now owing to their large percentages of
phosphorus and manganese, are useless
lor present purposes II is proper to
state, i'll this connection, that very
large deposits of this gossan are re-
ported IN Tennessee. on the southwest
crn extension of the lode. but AT present
unavailable by reason Of distance from
any railroad.
The gossans of Carroll arc now reach
cd by rail from the Norfolk and West
crn railroad at two points-at the north
eastern end by Il branch road 10 miles
long, from the Cripple Creek extension
at Big Reed Island creek, - miles from
Pulaski, 81 miles from Max Meadows.
III miles from Bristol. - miles from
Radford. 50 miles from Salem. 90 miles
from Roanoke and 40 miles from Lynch
burg. The lower or southwestern end
OF the lode is now reached by the Nor
iolk and Western extension OF the Grip
nlQ Crock lro11 tnt no
and iadlkin Valley railroad at the North
Carolina line. This brings this part of
the lead within II miles of Ivanhoc, 40
miles OF Pulaski, Ga miles of Radford,
los miles of Roanoke. 1t follows that
this ore IS commercially available at
every furnace either now blowing or
building, or projected. on the line of
the Norfolk and Western and Shcnan-
doah Valley railroads.
high grade limcstoncs and dolomitcs
arc to be had everywhere through the
great Valley of Virginia, and it is not
necessary to cucumber this paper with
detailed descriptions or analyses.
In considering the possibilities of Viz
ginia as an iron producing district. il
would be manifestly improper to call
attention to the fuels available, as no
matter how large the quantity. or how
cheaply obtained the ores might be.
they could not be utilized in the absence
of a proper fuel.
The merits of Flat Top Goals and coke
are now too widely known to warrant
elaboration. The cXccllcnce of the cox
ing Goals OF the New River district, on
the Chesapeake and Ohio Railroad, has
been too well tested in furnace practice
for years past to admit of doubt. The
coking Goals of the New River (Chcsa-
peake and Ohio railroad), upon which
the furnaces at present working the
Oriskany ores (No. VII, as abovc) de-
pend, are deliberately treated by j. c.
White, recognized authority, in his
report to the United States Geological
Survey in 1884.
He gives threee seams of coal. The
Nuttall, with its geological horizon on
New River, about 400 feet below the top
OF MI; the Quinnimont and Fire Creek,
from 300 to 400 feet below the Nuttall.
These seams run from feet to feet in
thickness. The coal literature of the
country has been flooded for the last 10
to 10 years with analyses of all these
Goals and coke. OF course these vary
according to the samples taken 1t is
believed that the following are fairly
representative
