Cob: cob or compressed earth retaining walls

[Darel Henman]

Tony,
  you will have to get the url below into one line I believe to
retrieve.  The picture is of a  block made by ramming a weathered
granite soil about 70% with slaked lime about 30% by volume, to about
half of its original unrammed size to compress it.  I suppose a lime
mortar of lime and sand was used to put it together.  Try making test
samples.
