So at length Carter crawled through endless burrows with three helpful ghouls bearing the slate gravestone of Col. Nepemiah Derby, obit 1719, from the Charter Street Burying Ground in Salem. When they came again into open twilight they were in a forest of vast lichened monoliths reaching nearly as high as the eye could see and forming the modest gravestones of the Gugs. On the right of the hole out of which they wriggled, and seen through aisles of monoliths, was a stupendous vista of cyclopean round towers mounting up illimitable into the grey air of inner earth. This was the great city of the Gugs, whose doorways are thirty feet high. Ghouls come here often, for a buried Gug will feed a community for almost a year, and even with the added peril it is better to burrow for Gugs than to bother with the graves of men. Carter now understood the occasional titan bones he had felt beneath him in the vale of Pnoth.
