“Note again.”
He made a short striking motion with the thing, similar to that which one would employ who had designed to jerk something out of the bowl. And at the very spot on the floor where any object contained in the bowl would have fallen, came a reprise of the bell note! Clearly, from almost at my feet, it sounded, a high, metallic ring.
He struck upward, and the bell-note sounded on the ceiling; to the right, and it came from the window; in my direction, and the tiny bell seemed to ring beside my ear! I will honestly admit that I was startled, but:
“Dyak magic,” said Colin Camber; “one of nature’s secrets not yet discovered by conventional Western science. It was known to the Egyptian priesthood, of course; hence the Vocal Memnon. It was known to Madame Blavatsky, who employed an ‘astral bell’; and it is known to me.”
He returned the little instrument to its place upon the cabinet.
“I wonder if the fact will strike you as significant,” said he, “that the note which you have just heard can only be produced between sunrise and sunset?”
Without giving me time to reply:
“The most notable survival of black magic—that is, the scientific employment of darkness against light—is to be met with in Haiti and other islands of the West Indies.”
“You are referring to Voodooism?” I said, slowly.
He nodded, replacing his pipe between his teeth.
