I recall decks of cards that were used to identify
plants, birds,
etc. ?Holes along the edges; you inserted knitting needles according
to observed characteristics and shook the deck. ?The cards left on
the needles (or maybe the ones that fell out; I can't recall) were
your candidates.
Yes, that is the idea. Apparently the women that used to do this were
very fast, and could do a sort in a blink of an eye.
