True distance keep in files, in ranks
Open close to the front, reare, flanks,
Backward, forward, to the right, left, or either,
Backward and forward both together.
To the right, left, outward or in,
According to directions given.
To order, close, open, double,
Distance, distance, double, double:
For this alone prevents distraction,
And giveth lustre to the action.
