Thephoto on page 6, taken from one of the higher seats at theside of the balcony, shows the appearance and position ofthese fixtures. Again the painting over the stage suffers becauseof these fixtures. They are all placed in the same plane andthe massive balls which form the centers of the fixtures andthe large number of arms that carry the lamps cast a ring ofheavy shadow all around the walls of the Auditorium.

The original installation here was of frostedlamps as it should be but some renewals have put in barelamps and the hig
