The Morgan Manning House, 151 Main Street, Brockport, will be the setting for the December 8 dinner for members of the Chili Historical Society. At 6 p.m. punch and hors d'oeuvres will be served in the library, followed by a buffet dinner at 7 p.m. in the dining room. As in past years, the house will be decorated in the traditional Christmas manner. The climax of the evening will be an auction of donated items, conducted by a celebrity auctioneer; those who attend should bring an item for the auction. Due to space limitations, this event is open to members and their guests only. Call Vesta at 889-2977 for reservations. Reservations must be in before December 3.
