noxious thing might be lurking in that abyss; but in a moment he mustered up the courage to peer over the rough-hewn brink, lying at full length and holding the torch downward at arm's length to see what might lie below. For a second he could distinguish nothing but the slimy, moss-grown brick walls sinking inimitably into that half-tangible miasma of murk and foulness and anguished frenzy; and then he saw that something dark was leaping clumsily and frantically up and down at the bottom of the narrow shaft which must have been from twenty to twenty-five feet below the stone floor where he lay. The torch shook in his hand, but he looked again to see what manner of living creature might be immured there in the darkness of that unnatural well; left starving by young Ward through all the long month since the doctors had taken him away, and clearly only one of a vast number prisoned in the kindred wells whose pierced stone covers so thickly studded the floor of the great vaulted cavern. Whatever the things were, they could not lie down in their cramped spaces; but must have crouched and whined and waited and feebly leaped all those hideous weeks since their master had abandoned them unheeded.
But Marinus Bicknell Willett was sorry that he looked again; for surgeon and veteran of the dissecting-room though he was, he has not been the same since. It is hard to explain just how a single sight of a tangible object with measurable dimensions could so shake and change a man; and we may only say that there is about certain outlines and entities a power of symbolism and suggestion which acts frightfully on a sensitive thinker's perspective and whispers terrible hints of obscure cosmic relationships and unnameable realities behind the protective illusions of common vision. In that second look Willett saw such an outline or entity, for during the next few instants he was undoubtedly as stark mad as any inmate of Dr. Waite's private hospital. He dropped the electric torch from a hand drained of muscular power or nervous co-ordination, nor heeded the sound of crunching teeth which told of its fate at the bottom of the pit. He screamed and screamed and screamed in a voice whose falsetto panic no acquaintance of his would ever have recognised, and though he could not rise to his feet he crawled and rolled desperately away over the damp pavement where dozens of Tartarean wells poured forth their exhausted whining and yelping to answer his own insane cries. He tore his hands on the rough, loose stones, and many times bruised his head against the frequent pillars, but still he kept on. Then at
