Cranvlllo Barker's Ideals.Granville Barker, who has -done so much for tho stage during recent years in London, has heeu interesting New Fork theatre-goers profoundly with his new ideas on stage productions. His wife (Miss Lillah M‘Carthy), \vho was Wilson Barrett's leading lady in New Zealand, was recently interviewed in New York. In the course of her remarks she’ said:. •“My husband and I are one, also, in the idea of. an ideal theatre. It would be a double • theatre, two; playhouses in one, for convenience built/stage to (stage.;..-.One would bo a workshop in which artists ‘ could experiment while the other would be the theatre proper. In .the workshop theatre the artists could: design scenes. The costumiercould strive there for telling effects. rio various systems, of lighting couldbe tried, and all now devices for the • stage wo rked * out. In this. workshoptheatre, at private rehearsals, tho dramatist could1 try'his how plays and so detect their defontcs.^ One of our most marked shortcomings in the theatre to-day is that -we take so little thought of trial, performances^ .'In this, our ideal theatre, we would have a gymna-. sium. Gymnastics and-dancing would bo taught thero to givoipoise of-body. And experienced : actors should and would give gladly of. their services for. the sake-of establishing tho best standards-of the stage. '“In any thoroughly in accord with myhusband in the way he goes ahout a new play that he is to do. -He first doter-mmcs what ho toms tho practicalities of the play. That is, what kind* of play it is and what manner of treatment it requires. He: works as hard as a draughtsman, on such apparent trivialities .as exits and openings, • what we .class as the physical side . of a play. One great :trut«h about my husband is-that'there is-not; a Granville Barker school, or manner, of treatment. He .attacks , each new . play with all'the freshness of view and openness to impression; and desire for individual treatment as though he were a beginner. He has1 no set form of production, not oven m tho'matter’of lighting.. Every •new play is a new problem.” 1
