trict. Four veins have been worked to a depth from one hun¬ 
dred to two hundred and sixty feet. These occupy a high hill 
four miles west of Clintonville. The first vein which was opened 
contained a beautiful blue and irridescent ore, both soft and 
granular. The next vein which is parallel with the first, furnishes 
a black ore, and the others a gray ore. The blue ore probably 
makes the softest iron of any ore in this country. The others a 
harder iron. The first is from four to eight feet wide, and the 
direction and dip of the four correspond, being north-northeast, 
and dip west-northwest, at an angle of 70°. The ore of all of these 
veins has been changed from that of a protoxide to a peroxide, 
as they all give a red powder, but the change is more descisive 
in the blue vein. The gangue is a blue gray quartz in the 
gray veins. 
These veins have been shifted simultaneously by dykes in a

About half a mile north of Clintonville, a mine worthy of a 
passing notice was opened at an early day. It is known as the 
Winter ore bed. The ore is hard, but being pure, it made a 
good iron, and as it was situated conveniently, it was desir¬ 
able to make the most of it possible. The vein reposed 
upon the top of the rock, and it excited attention from the 
novelty of its position. It was in the form of a flat superficial
