Bob,

I do see the approach you are taking. I am considering it.  The previous notes 
were just ideas off the top of my head on the subject.  The basic premise you 
are looking at is that tree A over time will change to be the height, girth, 
and form  of tree B over time.  (Actually it is the converse of that arguing 
tree B was the same size, shape and girth as form as A at some point in the 
past.)  On an individual basis that is an unlikely proposition, but as a 
statistical set of average trees, the arguments would appear to be valid.  If 
you had a big tree that was cut down.  And you were able to slice the trunk at 
various heights.  You could determine the the girth at a given point at a given 
time at a given height by counting backwards from the outermost ring. You could 
determine at what age the tree reached the height of that cut, and you could 
reconstruct the form of a particular tree and its volume at any give point in 
time.  The closer the slices together, the more detail you would have and the 
better you could reconstruct the tree in the past.
