Another interesting fact about the Bois d'Arc is early pioneer land surveyors made stakes out of them for use as property corners as they last a very long time, we still occasionally find them and they are treated like gold.
i would love to find 1 of those
at the family farm, in Melissa
they are on each corner of the house & porches
they are from 1890 & still hard as a rock
(in 2004, when they sold it, at least)
