The Huntsville (Ala.) Advocate informs us that an old silver mine has been re-discovered in Hancock county. It was walled up with solid masonry, which had to be removed by blasting before the mine eould be re-opened. Large trees are growing over and around it, 1 showing that it cannot have been opened for t centuries. The ore is aid to be very rich, *— Patent Claims FOR THE WEEK ENDIN&MARQH 2, 1858.
