2. Volte in file;

and, when the columns are again going forward on the right hand,

1. Prepare to half-volte in file.

The leaders turn to the right, describe their half-circle, and go forward on a diagonal line ending just behind the last rider in the column; once there, they turn to the left and fall into line, being duly followed by each pupil over the same ground.

When the leaders are about eighteen feet from the corner of the school, the teacher will order:

2. Half-volte in file.

The next order should be:

1. Prepare for the reversed half-volte in file.

The leaders must execute diagonals proportional to the lengths of their respective columns, in such a manner as will enable them to begin their half-circles when about thirty feet down the long sides, and thirty-five or forty feet before the turn or corner, followed in turn by the other pupils, as in the foregoing movements.
