Delphi Preservation Society is sponsoring several events this week during the Old Settlers celebration.

"Courthouses of Indiana" will be the topic of a presentation at 7 p.m. Friday in the Circuit Courtroom on the third floor of the Courthouse. Tommy Kleckner, Western Regional Director for Historic Landmarks Foundation of Indiana, will present an architectural and cultural review of many of Indiana's outstanding courthouses.

Free narrated trolley tours from 1 to 5 p.m. Saturday will showcase some of Delphi's oldest and most beautiful residences and businesses. The trolley will leave from the Murphy Fountain at the southwest corner of the courthouse square.

"Black Comedy," a oneact play, will be presented by Delphi's Red Brick Theater Company at 4 p.m. and 8:30 p.m. each day of Old Settlers. Admission is free, but donations are welcome and will benefit both the theater company and DPS. All but the last performance will be in the street-level Opera House Galley of Contemporary Art, in the back of the gallery. The last performance will be at 8:30 p.m. Saturday in the Delphi Opera House. Doors will open at 8:15 p.m., and seating is limited. "Black Comedy" is a farce set in a London flat during an electrical outage.

The art gallery will be open daily, and Opera House tours will be given daily at posted times.

The DPS will sell "roof beer" (root beer and root beer floats) to help put a new roof on the Delphi Opera House.
