“Another instance occurs on the Trneblood plantation, where the two 
ore-beds appear to be only 200 yards apart at their outcrops and seem to 
dip different ways, which I explain by reference to the false surface dip 
of the Sergeant Shaft and bed. The Trueblood section is as follows : 
The sections made at the Shaw plantation (Shaw range) furnish a fur- 
ther illustration of these irregularities. “ The ore-bed is full 8 feet 
across, solid ore,— -a very green, chloride, mica slate, rock-ore. In this 
run of 800 yards, there are apparently two hundred thousand (200,000) 
tons above water level , in the one 6 foot bed. The outcrop runs along 
the top of a hill about 100 feet above the bottom of Haw River Valley. 
There are apparent variations in the dip, some of the outcrops seeming 
to be vertical, whereas the principal part of the mining has already 
shown a distinct dip towards the southeast and south.” The average dip 
of the ore beds of this second range was observed by Dr. Lesley to be 
considerably less than that of the Tusearora beds, as is shown in the 
ideal section on page? 
The quantity of ore which this remarkable range is capable of yield- 
ing is obviously immense. The number and extent of the beds have 
been noted. Their size varies greatly, as is shown in several of the dia- 
grams. “ They consist of strings of lens-shaped masses, continually en- 
larging and contracting in thickness, from a few inches to 8 and S feet.
