Which gives Iron 42.73 per cent. This analysis places the ore among 
the best of its class. 
A second deposit, reported to be abundant, in superficial nodules and 
irregular lumps, is found in the southern part of Duplin county near 
Wallace, on the farm of D. T. Bonev. The following is a partial analysis 
of an average specimen from a box of about 50 pounds sent to the Mu- 
seum :

The ore is often in quite large and tolerably compact lumps, of a red- 
dish brown color, and slightly magnetic. 
Another bed of the same character and appearance, except in the size 
of the nodules, which are rather small, occurs in a field about 2 miles 
north of Rocky Point in New Hanover. 
Specimens of the same sort have bean frequently sent to the Museum 
from other points east, — 'Edgecombe, Pitt, Halifax and Robeson, for exam- 
ple ; showing that this kind of ore is of common occurrence in that 
region. 
Hematites of Halifax and Granville . — On the hills fronting the 
Roanoke, less than a mi.e below Gaston, are several outcrops of hematite 
ore. There are two principal beds, of which the lower only has been 
opened. The ore is granular, for the most part, and ot the variety known 
as specular, but contains a considerable percentage of magnetic grains 
disseminated through it. On the south side of the river, the bed has 
been exposed for several rods on the upper slope of the hill, at an eleva- 
tion of about 100 to 150 feet above the surface of the water. The ore is 
generally slaty, impregnating and replacing the argillaceous and quartzitic 
and chloride strata which constitute the Huronian formation at the lo- 
cality. This lower bed is double, another parallel outcrop appearing at 
the distance of about 100 yards. The strike is N. 20° E., and the dip 
eastward 80°. The principal bed is about 20 inches thick at the surface. 
There is a re-appearance of it on the other hill front about a mile distant, 
on the north side of the river, the ore being of the same character, but a 
little less slaty. It gave on analysis 63.76 per cent, of Iron, and 0.09 of 
phosphorus.
