given line ought to be sufficient to turn all geological observa¬ 
tions to that spot for the same purpose. 
I noticed in the third belt of mineral land slight disturban¬ 
ces of the strata, such as here and there protrusions of the 
lower magnesian limestone through the sandstone. This, to an 
unbiased geologist, would be sufficient evidence of the action 
of physical forces from below along the line of this belt, but 
to a man who will dispute every inch of progress science 
makes, it will weigh but little. I will therefore use it only as 
a guide to more important phenomena. 
The fourth and last belt is, as before stated, along the south 
flank of a well-defined elevation of land running parallel with 
the belt, with about the same eastern and western extension. 
I will not stop to describe this elevation or to show its relation 
to forces acting from below. The following quotation from 
the report of 1862 will be sufficient for this purpose. 
“The line of water-shed as represented on the above diagram, betwee 11 
the streams flowing north and those running to the south, is almost 
exactly a straight east and west line from the Blue Mounds to Prairie du 
Cliien. and for a distance of almost sixty miles. ***** 
No one observing the position of this line could fail to recognize the fact 
that its origin was due to some general, geological cause, as will be 
explained further on.” Page 103. 
On page 887 we have the following reference to the same 
elevation. 
“ As a proof or at least a strong indication that the axis of elevation was 
an east and west one, the fact may be here again alluded to which was stated 
in a preceding chapter in regard to the water-shed of the district being an 
exact east and -west line through the whole extent of the lead region.” 
Now the fact that the fourth belt is along a well defined ele¬ 
vation of land of the same bearing and extension, produced 
by the same general, geological cause acting from below as an 
elevatory force, proves beyond all doubt that the slight dis¬ 
turbances referred to in the next belt south, must be the result 
of the same, or a similar cause. And what can be a more 
logical inference, than that the other belts have the same origin, 
and that the phenomena of the whole district are the results 
of the same geological cause.
