Went on a field trip in the past few days to find Ulmus racemosa Rock-
Elm seed. Found none this year.
Don't whether it was due to a April frost or a skipping of annual
production. Plenty of Siberian Elm seeds
though, but don't know if I like this species or not. It is not an
endangered species.

And am finding out what makes hard and tough woods is rate of growth.
Has anyone put chemistry and
physics to rate of growth and why the wood is strong and hard?
Although hickory grows somewhat fast and
yet is strong whereas hophornbeam grows slow and is strong.

So has anyone translated slow growth with what? with a more compact
mass or a more dense mass? Or is
slow growth mean more fiber connections that act is glue? So what is
the chemistry and physics translation for

Slow growth = stronger and harder wood mass?
