Question for Fable: The Lost Chapters

In orchard farm, on the right side of the path that goes through the trees, there is a digable area. When you dig there it says you find nothing interesting. Does anyone know what this is and if it�s an item, what do you have to do to get it? I�ve found other places where you dig somewhere that it says you can, but it doesn�t give you anything. Then you do something, see a cut scene with that place, then you go dig there and you find something. A place like the grave outside the grey house, it says you can dig, but you don�t get anything. Then you go inside, kill zombies, watch scene, go outside, and dig the grave, then you get a tattoo. So if any one knows what it is, please tell me
