ABSTRACT
A major play, opera, fairy play, or ballet has just been performed with scene changes, elaborate stage effects, and all the necessary luxury of costumes and settings. It is an auspicious occasion to visit the stage to examine it from the ground to the roof. The floor of the stage is divided into a certain number of parts called “plans.” The substages are counted as they descend from the stage. The highest is for this reason called the first substage and so on in descending. The trappillons are small sized traps crossing the stage just onstage from the levee. They are attached with hinges at the tops of the frame on which they rest [the stage floor] and produce that bang heard when a set is raised onto the stage. They are beginning to be installed in a similar way to the traps, making them slide noiselessly into the levée at each side.
