Pat, fruiting frost pear wild seeded, I think it might be called Keifer variety. Large tree with pears that are hard till after the first frost.
sulfer, not much experienced with other white woods, but it is quick and very light.
Pear is very fine grained and stable. It would not form with dry heat, I tired on the cull before tillering. It has been used for fine measuring tools like architect's rulers for a long time. Very nice to work.
