Looks like Jill sent this just to me, so I'm forwarding.

Although I've deleted my own, ahem, deathless prose.  ;-)

I dug my floors down 20cm. Put 10cm of stone in and stamped it very well. 
Covered with cardboard to stop the stones piercing the cobb and then laid 
10cm of cob. We then lime rendered the floor with a 1 part builders lime and 
three parts building sand. Two layers of this. We left the floor to dry. 
When dry we slightly heated raw linseed oil and painted it on for first 
layer. We then did 3/4 linseed oil and 1/4 turpentine for second layer, also 
heated slightly to aid absorption. The third layer was half and half raw 
linseed oil/turps. The fourth layer we used 3/4 turps and 1/4 linseed oil 
and to that we added a 2parts pure beeswax to our 3 part turps/linseed oil 
mixture again heated and painted on. After a couple of days we buffed the 
floor and two years latter it is still lovely.
