My son and I were planting flowers today behind my house along our garage. I was pulling up an old rotted tree stump and out rolled a metal ball. It's about 2.5 inches across and pretty heavy. It's magnetic too. This tree stump was also surounded by pieces of flagstone that I dug up. Under the stump I also found an extremely hard pinecone and what looks to be a meteorite. We are renters and know nothing about this house, other than it's approximate age. We live in a part of Toledo, OH that is known for it's Victorian homes. South of Toledo is Fort Meigs and there were many other forts along the Maumee River. I have no way of knowing what this metal ball is but my son and I sure would like to believe it is from a cannon!
