Progress,  page 109
Here's the fireplace in action with a small fire going.  We've been using it this winter to heat the
house and it works great.  I'll eventually face the entire fireplace (including the seating areas)
with rock harvested from the lot but that will have to wait until spring so that the heat of the fire
doesn't prevent the mortar between the rocks from curing properly.
I even made a screen to contain projectile embers.  It fits nicely in front of the fireplace opening.
