After advising Christopher to use the humility approach at the hardware
store, I find that I'd rather be embarassed by asking you guys a
question than the alternative.  Below is a drawing.  Sorry if it bloats
your email.  I'm confused by the numbers in the centers of the
structural bays.  Is it reasonable that they represent the thickness of
the slab spanning two ways between the beams?  Why two numbers?  Is the
second number the depth of the beam?  Or is the first number...always a
"5", actually an "S" as in Slab?

Has anyone ever written a book on how to interpret the notes of long
gone draftsmen?  Particulary the ones in the engineering profession?
