GEOLOGY OF NORTH CAROLINA. 
beds are not defined at all ; the rock is worked in any direction where it 
is found to pay, and the excavations are made in the most irregular and 
undefinable fashion. 
Another ore-bed and two forges (Hyatt’s), are found on the west side of 
Ararat River, near the mouth of Bull Run Creek. This ore-bed is nearly 
west of the Pilot, in a light-colored slaty gneissoid sandstone. A third 
ore-bed, which has been worked for many years, known as Williams’, is 
four miles northwest of Rockford. The rock is a hornblendic gneiss, and 
the mode of occurrence of the ore is very much as on Tom’s Creek, 
but it is more disposed to gather into bunches and pockets and solid 
masses. The iron made from the ores of Surry has a good reputation in 
the region ; they are apparently very pure. On the south side of the 
river, there is a series of ore-beds running from the river in a southwes- 
terly course to Deep Creek, nearly across the county of Yadkin. There 
are a number of mines here, the most noted of which are the Ilobson 
Mines. The ores are very much like those on Tom’s Creek, but the 
beds are better defined, and the ore more concentrated in definite strata. 
The analyses below, by Dr. Genth, will show the character of the ores 
of this county :

The Hobson ores, several beds, are represented by Hos. 53, 51 and 57. 
These ores have been used in the forges of the neighborhood for many 
years. The ore-beds are in the northern part of the county, but others 
are found southward of them, and are represented by the other analyses; 
and the ores have also been used in the blomaries of the neighborhood 
for a long while. The other beds represented in the table are the Sand 
Bank (51), Black Bank (52), Hutchins’ (55), Dpper Bank (56), and 
Shields’ (58). At East Bend also is an outcrop of magnetic ore, which 
is coarse, fgranular, and more free of rocky matter than most of the other 
deposits ; but it has not been operated.
