UILI boast of tion' has become splendid nonsense. When the chorus of a Legible musical show breaks in into a particularly tune- the Dark. ful melody, and the words sound like a suc- cession of do-de-o-dos, it is annoying to find that the theatre program can give no immediate clue, because it is just another inky spot in a darkened house. To save its patrons such in- convenience, a London theatre has e adopted programs fashioned on the e principle of the radium-dialed watch. n When the lights are up, the pro- y grams appear simply to have a smart 1- new set-up of black paper with whive t, printing. When the lights are dimmed the white letters are slightly luminous, so that the program is is easily legible. A very small amount of radioactive substance is used in ly the manufacture of the ink, which also contains "another chemical ts which shines in the dark when acted on by rays emitted by the fe radioactive element. Although such by materials are expensive, it is said of that so little is required that the cost of the new programs is not :h much more than that for ordinary or printing. Such pandering to the convenience ir of the theatregoer is likely to spoil D- him. Instead of arriving well before the rising of the curtain in order to look through his program, he may now slip into arriving late, counting on reading as the play progresses.
