The stage itself extends from the curtain line to the back wall of the theatre, and from left wall to right wall. Under the roof of the stage, anywhere from sixty-five to ninety feet above the floor, there is a horizontal lattice work of steel or iron covering the entire spread of the stage, and known as the gridiron. The space on top of the gridiron is called the rigging loft. The roof of the stage over the rigging loft is a huge skylight, opened or closed from the stage. The skylight is made light-proof for matinee performances. On the gridiron are rigged the blocks and pulleys through which pass the lines attached to all the scenery that goes up in the air, or "up in the flies," which is the name given the space between the top of the proscenium arch and the gridiron. To take scenery up, is "flying it," in stage language, leaving the sight of the audience; whatever goes up "flies," and whatever is carried off to one side or back is "struck." The stage manager, when he wants the scene taken away, gives the order "strike" to the stage hands, or "grips," as they are called, who are on the stage level, and he pushes a button for the head-flyman in the "fly-gallery" to fly whatever scenery goes up.

There is a "fly-gallery," as it is called, usually ten to fifteen feet wide, some twenty-five to thirty-five feet above the stage level and extending from the front to the back walls of the stage on one side, against the side wall, usually of steel and concrete. Then there is the "paint-bridge," perhaps five feet wide, extending across the stage at the back wall from side to side, on a line with the "fly-gallery." Sometimes there is a "paint-frame" attached to the back wall on which scenery is painted. It is movable up and down. Sometimes twenty to twenty-five feet above the stage level is a light-gallery, on each side of the stage running parallel to the fly-gallery, but under it. These galleries are for the purpose of holding calcium lights and operators. Running from the back wall of the stage to the proscenium wall all the way of the fly-gallery on the front edge nearest the stage is the pin-rail, very strong and imbedded in the wall front and back of the stage; it holds all the scenery that goes aloft. When the scenery is raised, the "lines," as the ropes or cables are called in stage language, are pulled down and tied off to this "pin-rail." These lines attached to the scenery are usually in sets of three, sometimes four, and extend straight up through the blocks in the gridiron and across the gridiron down to the pin-rail in the fly-gallery. As they are usually fastened to three or four different points on each piece of scenery they are necessarily of three or four different lengths, but the lines are tied and handled as one at the pin-rail, and pulled all together. In a set of three lines, the line nearest the pin-rail is called the "short line," the next one the middle line, the far one the long line. "Trim it," you hear the order given. This means to "level" whatever piece of scenery it is. "Tie it off" is the way they direct that the lines be made fast to the pin-rail. In rainy or damp weather the ropes get longer; in dry they shrink; then it is necessary to "trim the drops," letting out the lines and tying them over before the performance. This is done under the direction of the master mechanic or stage carpenter. Often there is a counterweight or bag attached to the lines above the fly-gallery to help carry the weight of the heavy scenery as it is sent aloft to its resting place in the flies, out of sight of the audience and out of the way of everybody on stage.
The various drops are known on the stage as "solid," "cut" or "leg" drops. Borders about forty feet long by twelve feet deep, hung horizontally, mask in the top of all scenery, and hide the "flies" from the audience on the lower floor, and may be interior, exterior, foliage, straight, arched, or sky borders (plain blue). In troughs hung across the stage by steel cables from the gridiron, their height regulated from the fly-gallery, are the various border lights, each usually in three circuits, red, white and blue. These are hung at intervals of about six feet, the first being about that distance back of the act curtain and the others spaced about every six feet to the back wall of the stage. On the average practical modern stage there will be anywhere from four to seven border lights. On the stage, between the curtain line and first border light, are the first entrances, known as left first entrance and right first entrance. The right and left of the stage are always the dancer's right and left as she or he faces the audience. About six feet back of this is located the second entrance, and about each six feet interval is a successively numbered entrance, as "third entrance," etc. In a "full-stage" setting the last entrance to the rear is called "upper entrance." A scene in the space covering the entire first entrance is spoken of as being "in one"; in the second entrance, "in two." When one passes out of sight of the audience he is "off stage." The various entrances and exits are designated in writing and print by characters that carry their meaning plainly, as RUE (right upper entrance), L2E (left second entrance). So, too, with spoken directions on the stage. When you are told to "exit LUE," for instance, you are supposed to know that you are to go off stage at the left upper entrance. No one in the theatre ever speaks of standing "in the wings"; always it is "in the entrance."
The prompt side in a theatre is usually the left first entrance, though sometimes it is on the other side, where are located the electric switchboard controlling every light in the building, under the personal direction of the chief electrician, and a series of buttons above a shelf or prompt desk attached to the wall about the height of a bookkeeper's desk, where the stage manager makes his headquarters during each performance, the stage manager being like the captain or skipper of the ship. All signals are given by the stage manager, the buttons usually placed immediately above or at one side of the prompt desk, within easy reach controlling buzzers, lights or bells that tell as plainly as shouted words could do what is to be done and who is to do it. Sometimes lights flash to give directions and warnings, instead of the buzzer sounding. Every action of the stage hands below and aloft is directed in this manner from one central point of control by one master mind, the stage manager of the show.
The orchestra usually has a music room of its own somewhere under the stage or in the cellar of the theatre, where the musicians congregate before the performance and during their "waits." A buzzer or bell warning to them is said to "ring the orchestra in," and they are usually allowed about three minutes to get into their places in the orchestra pit after it sounds. There is also a "drop" signal buzzer or light to give the head flyman in the fly-gallery the signals that indicate when to raise and lower certain "drops," or hanging pieces. A bell would be heard by the audience and detract from the performance. A curtain buzzer or light gives the "warning" and "go" signals to the stage hands in the fly-gallery who are called "flymen," for raising and lowering the curtains or other scenery, like "drops," "borders," and any other pieces of scenery that have been "hung" to fly. In some modern theatres the switchboard and its operator are raised some ten feet above the stage. In such a case a buzzer signal from the stage manager's prompt desk directs the manipulation of the lights for the guidance of the chief electrician in his elevated perch, these signals being given at a certain "cue" in the performance, and he knows from his cue sheet, always before him, just what lights are required on each succeeding cue.
Stage dressing rooms are by law required to be separated from the stage proper by a permanent wall. Access to them is usually found near the front wall of the stage, seldom along the back wall. In modern city theatres dressing rooms are in tiers, as in the New Amsterdam Theatre, New York, where there are seven floors of dressing rooms reached by a private elevator used for no other purpose. The modern stage dressing rooms in city theatres have every known arrangement for comfort, sanitation and convenience.
Stage artists have no business in the front of the house, nor, conversely, have those whose employment is in the front of the house any business on the stage. Both keep their separate places at all times. Artists are always required to enter and leave the theatre through the stage door. All first-class managers forbid the artists to be seen in "the front of the house." Members of the company usually are required to report for matinee performances about 1:30 P.M. and for evening shows about 7:30 P.M., but always before the "half hour" is called, which is thirty minutes before the overture is played. The stage watchman, known as the stage door tender, is always at the stage door before and during a performance and permits none to pass in who are not directly connected with the stage end of the theatre, the day stage door tender being on duty usually from 7 A.M. to 7 P.M., and the night stage door tender from 7 P.M. to 7 A.M. The night watchman goes his rounds regularly throughout the night at required intervals, registering on a time-clock from different stations throughout the theatre building; all outer doors and windows are locked about one-half hour after the evening performance.
