Divination by smoke was sometimes practiced by magicians.
A few jasmine or poppy seeds were flung upon burning
coals; if the smoke rose lightly and ascended, straight into the
heavens, it augured well; but if it hung about it was regarded
as a bad omen. In parts of Europe, a pregnant woman would
place poppy seeds on a window sill if she wanted a boy; sugar
if she wanted a girl.
