fersonyi lle, just outside the town, show the existence of ore beneath the 
surface. Great quantities are reported two miles east of the town; and 
still more abundant exhibitions in the cove of Wolf Creek, behind Buck- 
horn Ridge, north of the forks of Wolf Creek, and opposite Rocky Gap. 
Immense shows are reported in Wolf Creek Valley, inside of (or south 
of) Rocky Gap. 
I have myself no doubt of the correctness of these reports, so far as 
surface exhibitions are concerned. And it is an old and good iron mas- 
ter’s maxim, that where there is plenty of blossom there will be plenty of 
good ore. The fact is geologically exact. For the blocks of ore on the 
surface of limestone land (like the masses of white quartz on the surface 
of a mica slate country) are the undissoluble parts of the original country 
left behind by the slow and imperceptible mouldering away and 
removal of the softer material. 
A downthrow fissure, also, traverses Wolf Creek, at the foot of Clinch 
Mountain, as shown in the following continuation of section 8, and this 
fissure brings the No. IV sandrock of the mountain (which surrounds 
Burke’s Garden) at a dip of 380°, down against the limestone of the val- 
ley. How far this fissure extends eastward I do not know ; but certainly 
beyond Rocky Gap.

of the Clear Fork of Wolf Creek, and this would favor the accumula- 
tion of iron ore. Another traverses the cove behind Buckhorn Ridge, 
cutting it off from East River Mountain. It is on this anticlinal that the 
Wolf Creek Cove ores exhibited. 
But there is another important fact not to be lost out of view. Through 
out Southern Pennsylvania, and as far eastward (along the belt of which 
we are treating) as the Lehigh and the Delaware, and so on th rough New 
Jersey in the one direction, and through Maryland and Virginia in the 
other direction, the horizon (or formation level) of the bottom of the 
Lower Silurian (formerly called ‘‘ Hudson River ’’) Slates, No. III, and the 
top of the Lower Silurian Limestones, No. IT, is a plate of brown hema- 
tite iron ore-bearing rocks. Many of our best and oldest mines, like the 
Balliott and the Moselem, between the Schuylkill and the Lehigh, are on 
the outcrop of this horizon, at the top of the limestone formation. Where
