"So the old poem tells, and so the famous painting illustrates," agreed Pursuivant, his smile growing broader. "Dunstan was, in short, exactly the kind of holy man who would make a sword to serve against demons. Do you blame me for being confident in his work?"

"Look here, Judge," said Jake, "what were those things that jumped us up?"

"That takes answering." Pursuivant had fished a handkerchief from a side pocket and was carefully wiping the silver skewer. "In the first place, they are extra-terrestrial—supernatural—and in the second, they are noisomely evil. We need no more evidence on those points. As for the rest, I have a theory of a sort, based on wide studies."

"What is it, sir?" I seconded Jake. Once again the solid assurance of the judge was comforting me tremendously.

He pursed his lips. "I've given the subject plenty of thought ever since you, Connatt, told me the experience of your friend here. There are several accounts and considerations of similar phenomena. Among ancient occultists was talk of elementary spirits—things super-normal and sometimes invisible, of sub-human intelligence and personality and not to be confused with spirits of the dead. A more modern word is 'elemental', used by several cults. The things are supposed to exert influences of various kinds, upon various localities and people.

"Again, we have the poltergeist, a phenomenon that is coming in for lively investigation by various psychical scholars of today. I can refer you to the definitions of Carrington, Podmore and Lewis Spence—their books are in nearly every large library—but you'll find that the definitions and possible explanations vary. The most familiar manifestation of this strange but undeniable power is in the seeming mischief that it performs in various houses—the knocking over of furniture, the smashing of mirrors, the setting of mysterious fires——"

"I know about that thing," said Jake excitedly. "There was a house over in Brooklyn that had mysterious fires and stuff."

"And I've read Charles Fort's books—Wild Talents and the rest," I supplemented. "He tells about such happenings. But see here, isn't the thing generally traced to some child who was playing tricks?"

Pursuivant, still furbishing his silver blade, shook his head. "Mr. Hereward Carrington, the head of the American Psychical Institute, has made a list of more than three hundred notable cases. Only twenty or so were proven fraudulent, and another twenty doubtful. That leaves approximately seven-eighths unexplained—unless you consider super-normal agency an explanation. It is true that children are often in the vicinity of the phenomena, and some investigators explain this by saying that the poltergeist is attracted or set in motion by some spiritual current from the growing personality of the child."

"Where's the child around here?" demanded Jake. "He must be a mighty bad boy. Better someone should take a stick to him."
