Hi.  I'm not sure why we're on this list - our email is 
mooseman at ix.netcom.com.  I think it may have been because my son was doing 
some research for a report on Roman building materials, and asked for some 
information.  Could you please delete us as we have nothing to add to your 
discussions.  Thank you.  Yvonne
