This trap underlies the beds last mentioned. About 20 feet all exposed & there may be a greater thickness, though it is impossible to tell whether this trap forms a component part of the Series or not.

Below the trap & also in the bed of the brook an extensive series of ribband red & green sandstone with white quartzite layers. Shale conglomerates also occur. Small irregular pebbles of green or red shale imbedded in quartzite or sandstone pale green or whitish colours. These beds lie even & regular enough but are somewhat corrugated.
