Explosion of a Powder mill.
--One of the small rolling or incorporating mills, at the Powder Works, near this city, exploded about 7 o'clock this morning, severely wounding four men--two of whom were in the mill and two outside. One of the men appears to be very severely injured — the others severely, but not dangerously so. There were only about sixty pounds of powder in the mill at the time, and the damage to the mills is very slight — so much so, that operations there have not been interrupted. The mills are so constructed that an explosion of one will not effect the other — nor do a great deal of injury to the mill in which the explosion occurs.--Augusta Constitutionalist, 4th.
