Ivanna Goatside

I have a bunch of firebricks, planning to sell some, but want to make sure I have enough left for a 6 inch system.
I want to make the whole J out of them including the riser.
Have Ianto et al's book and Paul's dvd'.
I forget if the book has description of how many and I haven't had time to watch Paul's dvd's.
The firebricks are size about 2.24x4.5x9 inches.
Thanks, I will check Ianto's book tonight also.
Searched this forum and also through google, couldn't find an answer except one that said 67, but I assumed that was for the feeder and burn tunnel, not the riser.
Maybe I'm wrong.

I don't know, but what Sepp describes sounds like a tree/bush/shrub.
That looks like groundcover to me.
Wondering if this is it
Salix hegetschweileri

Sepp talks about this in Rebel Farmer. Anyone know what the species name is for this? And maybe where in the U.S. it can be found?
Google search didn't reveal much.
