The Hamerell or Helderbygian section teaches two important things: first the general sandy nature of the entire shelf points to a proximity of the coast, and one Helderbygian barrier must lay not far to the west of Great Stone Reef. Further since the Shelf, barrier and the other eastern barriers were in existence prior to the post Coal movements these came then further accen- tuated and but the eastern margin of the coal field was effected because it lay over the shelf, barrier and this accounts why the pre-Coal beds are more crumpled than the newly hinged as far east as the Appalachian Valley barriers. Seemly the presence of true Middle Germanic coals in the higher New Scott land. I was much sur- priest to find them and at first thought they must be from the Middle Germanic. There is however not the dislikest doubt of their age being either New Scotland or just above. The section seen today is not complete over Lelms. The lower beds remind of the Mountainpore at the top corner of the shale and all of the Cretaceous is fine. Section. A late Devon Cretaceous is yet to be found.
