I am really lucky my garden has very few stones, it is a very old house and the land has been cleaned over the years. However what I was going to add was that the house was built from the stones and mud from the surrounding land. It is the method they used long time ago. There were no local bricks but the land has lots of stones which are nearly all oval and vary greatly in size. Some local farmers have great mounds of them which they haul out each year, it must knock the dodo out of their plows and harrowing equipment.
