He was regarding something that lay in the sand before him, something dark and bulky that moaned feebly. Presently, lifting his head, he rolled out a sonorous invocation across the black waters. From the blacks huddled under the trees there came a shuddering response, like a wind wailing through midnight branches. Both invocation and response were framed in an unknown tongue--a guttural, primitive language. Again he called out, this time a curious high-pitched wail. A shuddering sigh swept the black people. All eyes were fixed on the dusky water. And presently an object rose slowly from the depths. A sudden trembling shook me. It looked like the head of a negro. One after another it was followed by similar objects until five heads reared above the black, cypress-shadowed water. They might have been five negroes submerged except for their heads--but I knew this was not so. There was something diabolical here. Their silence, motionlessness, their whole aspect was unnatural. From the trees came the hysterical sobbing of women, and someone whimpered a man's name. Then Saul Stark lifted his hands, and the five heads silently sank out of sight. Like a ghostly whisper I seemed to hear the voice of the African witch: "_He puts them in the swamp!_" Stark's deep voice rolled out across the narrow water: "And now the Dance of the Skull, to make the conjer sure!" What had the witch said? "_Hidden among the trees you shall watch the dance of the Skull!_" * * * * * The drum struck up again, growling and rumbling. The blacks swayed on their haunches, lifting a wordless chant. Saul Stark paced measuredly about the figure on the sand, his arms weaving cryptic patterns. Then he wheeled and faced toward the other end of the glade. By some sleight of hand he now grasped a grinning human skull, and this he cast upon the wet sand beyond the body. "Bride of Damballah!" he thundered. "The sacrifice awaits!" There was an expectant pause; the chanting sank. All eyes were glued on the farther end of the glade. Stark stood waiting, and I saw him scowl as if puzzled. Then as he opened his mouth to repeat the call, a barbaric figure moved out of the shadows. At the sight of her a chill shuddering shook me. For a moment she stood motionless, the firelight glinting on her gold ornaments, her head hanging on her breast. A tense silence reigned and I saw Saul Stark staring at her sharply. She seemed to be detached, somehow, standing aloof and withdrawn, head bent strangely.
