At the Federation of Irish Beekeepers Association meeting in Gormanston,
there
was a very amusing presentation in the beeyard on this very topic.  The
gentleman
giving the presentation (whose name I cannot remember) stated in a very
heavy
Irish brogue, "The way to assess the temperment of a colony is to open up
the
hive and bless your bees, making the sign of the cross over the top bars.
If the
bees attack, you know they're from hell and you can be sure they're devils!"
