In the small wood near the fish-pond at Moddershall, a coal seam over a foot thick, and lying in grey shales is partly exposed in a gutter. The stratigraphical evidence is in favour of this coal lying high up in the sub-division and not of its belonging to a lower horizon as represented on the old edition of the map. Red strata of the Keele type are found on either side of the exposed grey measures, and the inclination of the strata from the outcrop of the base south of Longton to Moddershall would permit a considerable thickness ot red strata at the latter locality. The plants collected from the Keele Group at Hartshill and the Trentham boring are pronounced by Mr. R. Kidston to belong to Carboniferous forms. The fact that this group is everywhere underlain by the full thickness of the Newcastleunder-Lyme Group shows the strict conformity of the two. The contrary opinion has been expressed, but the apparent unconformity at Leycett, as shown on the old map, can be explained (p. 30), while at Blurton, the juxtaposition of the red Keele sandstone and Etruria Marls has been proved to be due to faulting. Palseontologically and stratigraphically, therefore, the Keele Group is allied to the Newcastle-under-Lyme Group, and should be included in the Carb...
