Place an eraser on the front desk of alternate rows. At a signal to
start the first child in each row takes the eraser in both hands and
passes it over his head to the child behind him. This continues till
the last child receives it. The last child runs forward with it,
running down the right aisle. On reaching the front seat, his entire
row moves one seat backward, so as to leave an empty seat in front.
The runner then sits down in the empty seat and passes the eraser
backward with both hands as before stated.
The changing of seats should be on the left side.
The game ends when each child is returned to his own seat.
