considerations against this view ave so strong, that I reject it without much 
hesitation ; and I give my reasons further on. 
The map, however, shows another ore belt running nearly parallel with 
the Tuscarora Forge Outerop, and at a distance of three miles from it. 
This is called the Highfield, or Shaw Outcrop. Beyond the Haw River 
these two belts approach each other, and are believed to unite in Rocking- 
ham County. This, and other considerations, make it almost certain that 
the Shaw belt is the Northwest outcrop of a synclinal basin, three miles 
wide, and that the Tuscarora Belt is the Southeast outcrop. Ifso, the 
Tuscarora ore beds descend, with a N. W. dip, to a depth of a mile beneath 
the surface, and then rise again as the ore beds at Highfield and Shaw’s ; 
thus:

Many of the outcropping ore-beds are, to allappearance, vertical; others 
dip irregularly, some southeast, others northwest ; some steeply, others 
gently. But all these are extremely local variations, confined to a few 
feet or yards of depth, and will not invalidate the general uniformity of 
northwest dip of the whole Tuscarora Belt, and southeast dip of the 
whole Shaw Belt. 
The following section of beds on (fig. 7) the Widow McCuisten plantation 
(14—15 miles), in a trench cut at right angles to the outcrop, 50 feet long, 
and from 4 to 8 feet deep, will illustrate these irregularities :—

Similar irregularities are noticeable everywhere. The miners say that 
the pitch of the outcrop of the ore-bed worked in the Sergeant Tunneland 
Shaft (9) was southeast for some distance down, after which it took its 
regular northwest dip, such as it now has in the shaft and tunnel at a
