“ The ash surface was staked off into square metres, and the substance carefully removed in order. Each stalactite, stalagmite and pilaster was measured, numbered, and removed in sections. Six human skeletons were found buried in the ashes. Seven-tenths of a cubic metre of animal bones were found: deer, bear, wolf, raccoon, opossum, beaver, buffalo, elk, turkey, woodchuck, tortoise and hog; all contemporary with man’s occupancy. Three stone metates, one stone axe, one celt and fifteen hammer-stones were found. Jacobs Cavern was peculiarly rich in flint knives and projectile points. ”
