This is the English name for Jack-Stones.
Where a number of children are playing together, test who can pick up
the greater number without dropping any, within ten minutes.
The oldest child should keep count, and also watch the time, in order
that no mistakes occur. The counter should have each of the players’
names written on a slate or piece of paper, with sufficient room for
his scores. When a Dibb or Jack-Stone has been dropped, this party must
commence afresh. He, however, may yet win; for his opponents may drop
many more Dibbs than he. The only score to count is after the last Dibb
has been dropped. A player might have reached a score of thirty or
more, but having failed to catch his Dibb, it drops and he must now
count one, two, and so on without regard to former count.
When the ten minutes have expired, the counter should call “Game,” and
the players must stop on the second.
