Extract

In the Geological Survey Memoir, “The Geology of the Coasts adjoining Rhyl, Abergele, and Colwyn,” Mr. (now Sir Aubrey) Strahan most truly observes (p. 18): “There is in scarcely any part of this country a more remarkable development of chert than that which overlies the Carboniferous Limestone of North Flintshire.”
