large amount of iron-making coal, to be used either raw or coked, can be 
obtained from this county, but it is capable of producing a very large 
amount of fuel, valuable for all ordinary uses. 
LEAD. 
Almost every county has its bocal traditions of lead mines formerly 
worked by the Indians; and the testimony is often as positive as second- 
hand testimony can be, pointing to a definite location from which the_ 
Indian hunters obtained their supply of this metal. Such a location is 
definitely pointed out in Mechanic township, and old markings upon the 
forest trees are claimed to be signs made by the Indians to indicate the — 
precise location of the deposits. These traditional rumors obtained more 
credence here, from the fact that the valley indicated is filled with the 
buried Ferruginous Shale mentioned on a preceding page, which shows 
plainly the action of fire; and, as no other explanation was suggested, 
this cinder-like material was assumed to be the result of fires kindled 
for the purpose of smelting the lead-ores. The Indians were no archi- 
tects, and erected nothing deserving the name of buildings, either for 
residences or store-houses; and it is probable that all these traditions 
have their origin in the fact that they were compelled to ensure safety 
of all their surplus supplies by burying them in the earth. Such de- 
posits of lead, known only to a few, and visited by stealth, would readily 
give rise to the traditions of lead-mining. This cinder-like material is 
plainly the result of the burning-out, locally, of a coal seam; and the 
Coal Measure rocks which are here alone exposed, show no evidences of 
lead in any quantity whatever. A little lead and zinc are occasionally 
found in the Waverly, but the quantity is exceedingly small, and it may 
be regarded as quite certain that there are no valuabie deposits of either 
of these minerals in the county. 
DIP OF THE COAL MEASURES. 
It has been previously claimed, that there is a substantially uniform 
dip in the Coal Measure rocks, in a north-eastern direction, and that this 
is so even and regular that, having determined its rate and direction, a 
topographical survey will enable one to locate any member of the series 
in any other part of the field. All the results of my explorations tend 
to show that this claim is unfounded—that while it may be, and often is, ' 
true of particular localities, and over limited areas, the fact is, that the 
rate and direction of this dip are constantly varying, and that in places 
she dip is in the opposite direction from what it would be if this claim 
were well founded. :
