The conclave opens officially (now) not later than eighteen days after the pope's death. The cardinals assist at Mass and receive holy communion from the hands of the Cardinal Dean, who solemnly adjures them to elect as pope him whom they believe to be the most worthy. They assemble in the Sistine Chapel, where the actual voting takes place. The stall of each cardinal has a canopy overhead and a small writing-desk in front. The door is shut and bolted and the voting begins. Each cardinal having written the name of his candidate on the paper provided, deposits it in a chalice on the altar, taking as he does so the required oath: "I call to witness the Lord Christ, who will be my judge, that I am electing the one whom before God I think ought to be elected." The ballots are then counted and read aloud, and if no candidate has received the necessary number of votes, they are burnt in a little stove together with a handful of damp straw. As the chimney of this stove extends through a window of the chapel, the colour of the smoke or _sfumata_ can be clearly seen by those outside. Not until the election is made are the ballots burnt without the accompanying straw, when the clear white smoke is the first notification to the people that the pope is elected. Voting takes place twice a day, morning and evening, until a majority of two-thirds of the votes has been attained. The _veto_ was the alleged right of certain Catholic rulers to object to the election of a cardinal of whom they do not approve. It was exercised rarely and has never been formally approved by the Church. Although Pius IX had forbidden any interference by the secular power in a papal election, an attempt was made to exercise the _veto_ at the conclave which resulted in the election of Pius X. At the third scrutiny, in which Cardinal Rampolla came first with twenty-nine votes, Cardinal Puzyna, Bishop of Cracow, who had accepted the mandate of the Austrian government in the name of the Emperor Francis Joseph, read (it is said after signs of severe embarrassment) a declaration excluding Cardinal Rampolla, without giving any reason for the exclusion. The cardinals protested against the interference, and the votes in Cardinal Rampolla's favour were found to have increased by one in the evening scrutiny. But Cardinal Sarto's had been mounting steadily from the beginning and continued to do so until they reached the number of fifty.[*] [*] The opinions of those best qualified to judge seem to agree that Cardinal Rampolla's failure to be elected was quite uninfluenced by the Austrian action. Soon after his election Pius X definitively abolished the exercise of the veto.
