“And to what do you attribute this privilege?”

“I will tell you the tradition that has been handed down. You remember that I told you that Savilia died leaving two sons.”

“Yes, I recollect.”

“Well, these children grew up concentrating on each other the affection they would have bestowed on other relatives had any been alive. They swore nothing should separate them, not even death, and after some incantation or other they wrote with their blood on two pieces of parchment, which they exchanged, the reciprocal oath that whichever died first should appear to the other at the moment of his own death, and, subsequently, at every important epoch of his brother’s life. Three months afterwards one of the two brothers was killed in an ambuscade at the moment when the survivor was sealing a letter addressed to him. Just as he was pressing the signet upon the burning wax he heard a sigh behind him, and, turning round, perceived his brother standing behind him, and touching his shoulder, although he felt no pressure from the hand. Then, by a mechanical movement, he held out the letter that was destined for his brother, the spirit took the letter and disappeared. On the night before the survivor’s death, the ghost appeared again.

“There is no doubt that the brothers not only made this engagement for themselves, but it applies also to their descendants, for spirits have appeared not only at the moment of the death of those who had passed away, but also on the eve of any great event in their lives.”

“And have you never seen any apparition?”

“No; but like my father, who, during the night preceding his death, was warned by his father that he was about to die, so I presume my brother and I inherit the privilege of our ancestors, not having done anything to forfeit it.”

“And is this privilege accorded to the males of the family only?”

“Yes.”

“That is strange.”
