_A Cob-wall._--Why do the inhabitants of Devonshire call a wall made of
tempered earth, straw, and small pebbles mixed together, a _cob-wall_?
Walls so constructed require a foundation of stone or bricks, which is
commonly continued to the height of about two feet from the surface of
the ground. Has the term _cob_ reference to the fact that such a wall is
a superstructure on the foundation of stone or brick?
