At this point Panhandle paused to relight his cigar, and I took the opportunity to make a remark.

"Count it no grievance," I said, "if one who shoots at psychologists is himself occasionally shot at. I surmise that the truculent youth was the ghost of a promising psychologist, foully murdered by your nefarious gun."

"Name it a righteous execution, and I shall agree," he answered.

"Or it may be," I added, "that many of the sudden and inexplicable pains that break out in our minds and in our bodies are caused by ghosts, or whatever you call them, shooting at us, or stabbing us, to test our reality."

Panhandle turned a keen glance at my face to see if I was serious, and, being satisfied that I was, continued:

'We will arrange that a committee of the Society shall make a thorough examination of the house and test the phenomena. Don't forget to engage two shorthand writers and an expert in spirit photography. And let the room be sealed up till the experts arrive.'

As I walked over to where he was standing he saw me plainly, and showed not the least surprise on being addressed.

"'What is your name, my little man?' I asked.

"'Billy Burst,' said he.
