II. The Lower Carboniferous Rocks of Northern Britain

Abstract

Introduction. Between the summer of 1867 and the close of 1879 I was almost continuously engaged with Professor Hughes upon the Geological Survey of the Dales of North-west Yorkshire, and the adjacent parts of North Lancashire and East Westmoreland. This district embraces the whole of the typical Yoredale area. In the course of this work I made detailed measurements of almost every section exposed, and plotted over 72,000 feet of these, on a uniform scale of 40 feet to an inch. I also had the advantage of studying the Lower Carboniferous Rocks of the northern half of Westmoreland, and much of both Northern and North-western Cumberland, as well as of some parts of Northumberland adjoining Roxburghshire. Lastly, during a residence of thirteen years in Edinburgh, a large part of my time, when not engaged officially, has been occupied with the study, in the field, of the Lower Carboniferous Rocks of Scotland. In this part of my work I have gained much knowledge from a study of the publications of the Geological Survey, and have especially learned much that is of value from the writings of Mr. H. M. Cadell and Mr. W. Gunn, F.G.S., on the geology of the east side of Scotland, and from those of the late Dr. John Young, F.G.S., and other geologists of the west country, for that side of Scotland. Mr. John Henderson's writings on the Lothians have also given me much help; and I have to thank my colleague, Mr. This 250-word extract was created in the absence of an abstract
