daub vs. cob

[Paul Valerio]

Hi Folks,

Does anyone know about "wattle and daub"?  After learning about "cob"
recently, it occured to me that the house my mother grew up in England
must have been a cob house because I know it has thick walls, a thatched
roof, and is very old ( apparently almost 400 years old ). 

I asked my mother about it, but she didn't have a clue!  ( Duh, somebody
kick me in the head - I could have built a cob house years ago and been
living debt free all this time!) I then wrote to my 93 year old granny
in England and she responded that the house was built using wattle and
daub.  The dictionary says "wattle" is a framework of timber and "daub"
refers to the mud/straw mix.

So the question is concerning "daub" vs. "cob".  Is it all the same or
not?
