The Conclave for the election of a Pope begins with the Mass of the Holy Spirit chaunted in the Chapel of St. Gregory. Afterwards, the cardinals go in procession, singing _Veni Creator Spiritus_, to take possession of the cells which they will have to occupy. These cells are erected in a hall of the Vatican, communicating with the Xystine Chapel. They are mere frameworks of wood hung with fringed curtains of baize, green in the cases of cardinals who are creatures of previous pontiffs; violet in the cases of cardinals who are creatures of the pontiffs just deceased. On the front of each cell is a curtained doorway over which the armorials of the occupant are shewn, surmounted by a little swinging window. Each cardinal has a bed, a table, and a chair. His attendants support life in discomfort as best they may. Three hours after avemmaria, all doors and windows communicating with the outer world are walled up. Guards on the outside watch every avenue of access, under command of the Hereditary Marshal of the Church, now Prince Chigi, then Prince Savelli. To every cardinal are allowed two conclavists for his attendants, a chaplain and an esquire. A cardinal-prince, or one aged and infirm, may add a third. In addition to the cardinals and the conclavists, there are enclosed a sacristan with his subsacristans, a secretary with his undersecretaries, five masters of ceremonies, a confessor, two physicians, a chirugeon, two barbers, an apothecary, with their respective boys, a mason, a carpenter, and servants for menial work. Great care is taken that none of these lay-persons should be agents of the orators of the secular powers; and they are made to swear a stringent oath of secrecy. As a matter of fact, they are not allowed to know anything of the proceedings in the Xystine Chapel. Meals are served at stated hours, through a revolving cupboard (ruota) in the outer wall, supervised by cardinals-inspectors. Flagons are of bare glass, lumps of bread or meat are cut open, that no messages from the outer world may pass in by these means. Nor may any single thing pass out. Urgent private letters written in the Conclave are subject to cardinals-censors. Cardinals, who have need, may speak to visitors, but in presence of witnesses; and all communication must be open, and in a language that all can understand. These interviews take place at a window, the cardinal being on the inside, his visitor on the outside: but the conclavists and others are forbidden to approach the window on any pretext whatever.
