An interesting locality 2 miles northwest of North Hillsdale was found in the middle of the road where the overflow from a roadside marsh crosses the road to lower ground on the other side. This occurrence consisted of a nodular aggregate pavement of wad, the writer's attention being called to it by the dark manganiferous nodules, looking much like a conglomerate consisting of dark pebbles in a whitish cement.
