Rubble, Rubble Work, Rough Walling,
coarse walling constructed of rough stones, not large, but of great irregularity both in size and shape, and not so flat bedded as in rag work. In some districts it is often formed of flints: in large buildings, in neighborhoods where better materials can be obtained for the outer face of the walls, it is in general only used for the insides, or backing; but in other districts the whole substance of the walls is not unfrequently of this construction. It is often found to have been plastered on both sides, but sometimes it was only pointed externally.
