VATICAN CITY - APRIL 15: A worker puts the chimney on the top of the Sistine chapel on April 15, 2005 in Vatican City. Since 1878, white smoke from the Sistine Chapel chimney signaled a new pope was chosen, and black would mean that deliberations continued. The conclave begins on April 18, 2005, John Paul II's successor will be announced traditionally with smoke from the chimney on thr Sistine Chapel and the riniging of the bells of St. Peter's Basilica.
