Kane gazed, awed. This was truly a hell on earth. As in a nightmare he looked into the roaring red cauldron where black insects fought against their doom and perished. The flames leaped a hundred feet in the air, and suddenly above their roar sounded one bestial, inhuman scream like a shriek from across nameless gulfs of cosmic space, as one vampire, dying, broke the chains of silence which had held him for untold centuries. High and haunting it rose, the death cry of a vanishing race.
