The competing rows must be placed where there is a blackboard at the
front of each row. First player of each row has a piece of chalk. At
the signal he runs to the board and makes a mark with the chalk, then
he returns to his seat, and hands the chalk to the next player, who
runs and marks in his turn. Later, players may be required to make
a cross, circles, capital letters, small letters, add columns of
numbers, write words, construct sentences. The teacher is the judge
as to whether the marks come up to the requirements, and each team is
charged with a foul for each defect.
