Additional Points in Stratigraphy.

In my paper published in the Proceedings of the Dorset Field Club (vol. xxiii), I dwelt at some length on certain borehole sections made towards the northern base of Creechbarrow with a view to the discovery of Pipeclay. This course was adopted in the hope that a study of these sections might throw some light on the stratigraphical relations between the Creechbarrow Beds on the hilltop and the Pipeclays lower down, if indeed there are any stratigraphical relations beyond a mere jumble of irregular deposits whose precise orientation can never be disentangled. Whether this latter supposition is the true one or not, the exceptional character of the Creechbarrow Beds, as a local feature, remains the same, even although we cannot decide whether they go under, over, or into the Pipeclay series. Before attempting any further speculation as to the possible stratigraphy of the region I will call attention, at any rate, to its topography as shown in the accompanying figure.
