“ Kinnison stayed. So did VanBuskirk, fighting with all his stubborn Dutch mind. Revolted, outraged, nauseated as they were at the sights and sounds, they stayed. Flinching with the victims as they were fed into the hoppers of slowly turning mills; wincing at the unbelievable acts of the boilers, the beaters, the scourgers, the flayers; suffering themselves every possible and many apparently impossible nightmares.The light in the cavern now changed to a strong, greenish-yellow glare; and in that hard illumination it was to be seen that each dying being was surrounded by a palely glowing aura. ”
