Hi Karl and everyone,

I will have to look for the lava earth.  I looked it up on the Internet
and didn't come up with anything. Is there a product name to look for?
I'm going to try and make it to the Viktoras Kulvinskas talk in San
Francisco that Tom Billings mentioned.  I just looked at my Survival
into the 21st Century book and it was written in 1975! It's raining a
lot, so I hope we all make it there!  Mary J.
