Plutarch, in his essay on the dæmon, describes how the souls of enlightened men return to be the schoolmasters of the living, whom they influence unseen; and the mediums, should we ask how they escape the illusions of that world, claim the protection of their guides. One will tell you that when she was a little girl she was minding geese upon some American farm and an old man came towards her with a queer coat upon him, and how at first she took him for a living man. He said perhaps a few words of pious commonplace or practical advice and vanished. He had come again and again, and now that she has to earn her living by her gift, he warns her against deceiving spirits, or if she is working too hard, but sometimes she will not listen and gets into trouble. The old witch doctor of Lady Gregory's story learned his cures from his dead sister whom he met from time to time, but especially at Hallowe'en, at the end of the garden, but he had other helpers harsher than she, and once he was beaten for disobedience. Reginald Scott gives a fine plan for picking a guide. You promise some dying man to pray for the repose of his soul if he will but come to you after death and give what help you need, while stories of mothers who come at night to be among their orphan children are as common among spiritists as in Galway or in Mayo. A French servant girl once said to a friend of mine who helped her in some love affair: "You have your studies, we have only our affections"; and this I think is why the walls are broken less often among us than among the poor. Yet according to the doctrine of Soho and Holloway and in Plutarch, those studies that have lessened in us the sap of the world may bring to us good, learned, masterful men who return to see their own or some like work carried to a finish. "I do think," wrote Sir Thomas Browne, "that many mysteries ascribed to our own invention have been the courteous revelations of spirits; for those noble essences in heaven bear a friendly regard unto their fellow creatures on earth."
