Abstract
THE Maryland Geological Survey has always been noted for the educational aspect of its publications, which are by no means a dry record of observations for the use of scientific specialists They help the ordinary citizen to understand his State, and in so doing to appreciate the aims and methods of research. The results of much careful work in petrology and palaeontology are brought together in the well-known green-covered volumes, so as to be accessible in private libraries and in schools. The present volume, by R. S. Bassler, covers a part of the Atlantic slope from the crest of the Alleghanies to the sea, thus including the three great belts of contrasted scenery that stretch from New England to Mississippi. The British controversy as to the nomenclature of the older Palaeozoic systems is interestingly re-stated, and the author, on grounds of fairness to the original workers, would like to use Taconic and Cambrian for the systems now styled Cambrian and Ordovician respectively. He effects a proper compromise, however, and fairly discusses Ulrich's Ozarkian and Canadian systems.
