the expense to prove this mine further than it has yet been 
done. 
“ At a small expense the value of this discovery could be 
determined, by ascertaining to what extent the ore is likely 
to traverse the magnesian limestone before entering the sand¬ 
stone, in w r hich latter formation the vein would probably dwin¬ 
dle or entirely disappear.” 
A few miles south and east of the above, copper ore has 
been discovered, of as rich, and apparently as extensive depos¬ 
its as the other, and in a short distance from that, lead ore has 
been found, indicating large deposits. 
In many parts of the county iron ore is very abundant, 
cropping out in ledges, easy of access, and of excellent 
quality. No one has yet attempted to open these mines of 
iron. They lie from three to eight miles from the Mississippi 
or railway. Capital could be profitably employed in so doing. 
The demand for pig metal and castings is very great, all of 
which now are brought from the East at great expense. 
In connection with this v r e may add, that quarries yielding 
quick lime and w r ater lime are numerous ; and that marble, 
quite equal to the Vermont marble, is cropping out of the hill 
back of this place.

or who gazed with awe upon the mighty Mississippi. The 
spirit of religious enthusiasm explored the basin of the great 
lakes and the valley of the Mississippi. From Quebec the
