This is the final article in a four-part series on folk customs in Yorkshire. There are photographs and descriptions of the well known pace-egg plays of the Calder Valley but the article also includes comments and photos of other mumming groups performing in West Yorkshire. Smith does not ignore the mystery plays of York and there are illustrations of the pageant wagon performances which formed part of the York Early Music Festival of 2002. If the four-year cycle is repeated the next performances are due in 2006. The plays are well worth seeing.
