ORGAN KNOWN AS THE HOPE-JONES UNIT ORCHESTRA, IN THE PARIS THEATRE, DENVER, COLORADO. This fine instrument was installed in May, 1913, and hailed by the people of Denver with great enthusiasm. The president of the Paris Theatre Company, writing under date of June 9, says: "The wonderful instrument * * * is proving a source of interest to the whole city and has materially added to the fame of 'The Paris' as the leading picture theatre of Denver. No thirty-piece orchestra could accompany the pictures so well as the Hope-Jones Unit Orchestra does. Neither would it so completely carry away with enthusiasm the crowd that flock to hear it." [Illustration: The Author Playing a Hope-Jones Unit Orchestra.] Only the keyboards are visible from the auditorium; the instrument is placed on each side of the proscenium, occupying the place of the usual stage boxes, the tone being reflected into the theatre through ornamental case work. The 32-foot open diaphone is located behind the picture screen. The specification: PEDAL ORGAN (32 NOTES). FEET. FEET.
