_tormentor_ has been able to give it. They all say they have asked
old-time stage-carpenters, but even they did not know.

It is in One that monologues, most "single acts"--that is, acts
presented by one person--and many "two-acts"--acts requiring but
two people--are played.

Behind the tormentors is a curtain called the "olio," which
fulfills the triple purpose of hiding the rest of the stage, serving
as scenery for acts in One and often as a curtain to raise and
lower on acts playing in the space back of One.

2. Two

Five, or six, or even seven feet behind the tormentors you have
noticed another set of wings which--extending parallel with the
tormentors--serve to mask the rest of stage. The space between
these wings and the line of the olio is called "Two."

In Two, acts such as flirtation-acts--a man and a woman playing
lover-like scenes--which use scenery or small "props," and all
other turns requiring but a small playing space, are staged.

3. Three

An equal number of feet back of the wings that bound Two, are wings
that serve as boundaries for "Three."

In Three, playlets that require but shallow sets, and other acts
that need not more than twelve feet for presentation, are played.
