I'm trying to understand what is known as Eichhorn's rule in terms of its claim
about nature.  Because most of the original articles were in German (and I'm
reading translations) with some recent ones in French (and I've forgotten most
of my French), I'd appreciate it if someone could set me straight!

As a proposition, it appears Eichhorn's rule states:

"Stands of the same mean height have the same volume" [it takes stands on poor
sites longer to get to a specified height, but when they do reach that height
they will all have the same volume]

But, how is density handled in Eichhorn's rule?

Is there a "rule" here yet, or is it a "rule in process" of being refined?  [All
'rules' probably are, I suppose.]

I'd appreciate any help unravelling Eichhorn's rule and his 'extended rule'.

Thanks,

Rolfe
