<Dd> The Yule log is generally given, and is at once put on the hearth . It is unlucky to have to light it again after it has once been started, and it ought not go out until it has burned away . </Dd> <Dd> To sit around the Yule log and tell ghost stories is a great thing to do on this night, also card - playing . </Dd> <Dd> Two large colored candles are a Christmas present from the grocery . Just before supper on Christmas Eve (where furmety is eaten), while the Yule log is burning, all other lights are put out, and the candles are lit from the Yule log by the youngest person present . While they are lit, all are silent and wish . It is common practice for the wish to be kept a secret . Once the candles are on the table, silence may be broken . They must be allowed to burn themselves out, and no other lights may be lit that night . </Dd> <P> H.J. Rose records a similar folk belief from Killinghall, Yorkshire in 1923: "In the last generation the Yule log was still burned, and a piece of it saved to light the next year's log . On Christmas morning something green, a leaf or the like, was brought into the house before anything was taken out ." </P>
