House
Many stone cottages are built of flint or "rubble" or "cobble". These are broken stones that are brought from nearby hills, or stones picked up from the farmer's fields, or gathered from a river bed. The walls are built up with stones and mortar. In some places where flint is used, the hard stones are split or "knapped" so that when they are placed on the outside of the wall, they show a shiny flat surface which is more attractive than the dull lumpy outside of a flintstone.
