A question on the subject of building materials --- I've just returned from a
short visit to France where spent most of my time focused on palaeolithic caves
and stone tools.  Naturally I spent alot of time looking at wonderful objects
made from what the French call "silex."  Having the image of silex handaxes
still fresh in mind, I also visited the English town of Canterbury and was
surprised to find there original walls faced with what looked for all the world
like debitage. I was told they call these walls "flints."  They are attractive,
a mottled charcoal grey or black and quite sharp to touch---I imagine nasty to
climb.  Is someone out there familiar with flint wall construction?  Please
forgive my California-born ignorance -- are there such structures in the U.S.?
Couldn't help wondering if the flints used might have--inadvertantly?--included
prehistoric flint artifacts.  Any known cases of this?
