Book Description
A symposium on "The Grenville Problem" was arranged for the annual meeting of the Society at Toronto in 1955 to discuss all aspects of Grenville geology. Several of the papers presented were assembled in this publication.

Book Description
Mountain ranges are the most conspicuous elements of the earth's architecture, and the manner in which the architectural units are arranged or disarranged has become the study of a subdivision of geology known as Tectonics. A hundred years ago James Hall attempted the first scientific synthesis of the steps in the building of the eastern North American mountains, the Appalachians. His initial hypothesis of 1857, expanded and broadened by J.D. Dana during the decade which followed, laid the foundation for our modern geosynclinal theory of mountain building. During the last century of modifications and refinements were contributed concerning the roles played by crustal compression, sub-crustal convection currents, batholiths, metamorphism, gravity sliding, and isostasy. In recent years detailed mapping, supplemented by studies of turbidity currents, paleomagentism, stable isotopes, and radio-activity have helped to unravel the history of mountain building, but today there are as many questions unanswered as there are those for which there are tentative solutions. Aspects of Appalachian orogeny was a suitable subject for the symposium of the Royal Society of Canada Annual Meeting in 1966 at Sherbrooke, Quebec—a city within the Appalachian Mountain System. This book assembles the papers of this symposium, dealing with gravity sliding, studies of sedimentation and structure in limited areas, comparisons with the Appalachians of the United States, the bearing of gravity measurements upon our understanding of mountain structure, earthquakes, and a broad, general view of the tectonic pattern of the earth of which this mountain-built belt is but a small part. Such a comprehensive volume, bringing together a variety of points of view of some of the foremost scholars in the field, indicates the vastness of the subject, the significant progress made thus far, the necessity for new and progressive methods of exploration, and above all the interdependence of all the workers in the field, no matter how seemingly unrelated their specialities are.

Book Description
A symposium of the Royal Society of Canada was held in June 1962 to outline what is being done in Canadian oceanography to map salinity, temperature, and plankton in the waters around Canada and in the North Atlantic across to Europe. This volume, based on the symposium, emphasizes the interdisciplinary nature of research in marine biogeography and in the distribution of environmental factors in the sea. The book is intended to show the breadth of biogeographic work in the sea, and the relation between biogeography and the physics and chemistry of the marine environment. It serves also to introduce to the scientific public the new Serial Atlas of the Marine Environment, a scientific journal of a new kind of sponsored jointly by the Royal Society of Canada and the U.S. National Academy of Sciences.

Book Description
The possibility that the continents of the earth have undergone major changes in position during the earth's history has fascinated scholars for at least three hundred years. Recently, evidence from several scientific disciplines has shown that the possibility must be very seriously considered in any study of the surface features of the earth. The first part of this volume consists of papers given at a symposium on continental drift, held at the annual meeting of the Royal Society of Canada in Charlottetown in June 1964. They present the views of three geophysicists, a botanist, and an astronomer. In these papers, the present evidence for or against continental drift is reviewed and the authors in most cases draw their own conclusions. The reader will find that there is not unanimous agreement in favour of drift. Nearly all discussions of continental drift stress the possible separation of the Americas from Europe and Africa. Considerable work has been done on the tracing of structures, on each side of the Atlantic Ocean, which might once have been connected. Geologists and geophysicists working in the Arctic or on the eastern seaboard of Canada have an important contribution to make to this subject. The second part of this volume, therefore, consists of a group of papers, also presented at the Charlottetown meeting, which throw light on the complicated crustal structure of these regions. In any attempt to reconstruct North America as part of Europe the features described in these papers will have to be taken into account. Once again, the reader will find differences of opinion on the question of whether the evidence favours a separation of our continent from Europe. Indeed, it is because the theory of continental drift us so difficult to confirm without ambiguity by direct observation that it remains controversial but exciting.

Book Description
The Transactions of the Royal Society of Canada for the years from 1929 to 1937 included a series in nine parts of important papers on "Crucial Maps" which have been a frequent source of reference ever since for students of the history of discovery and of early cartography. Their author, William Francis Ganong, had a life-long interest in the natural and human history of his native province, New Brunswick. Although he was primarily a botanist, with four full-length books and an amazing number of articles to his credit, it was through his series of monographs in the Transactions of the Royal Society of Canada that the breadth of his interests became known. For over fifty years he contributed almost annually to the Transactions the results of his systematic investigations into New Brunswick's physiography, aborigines, early explorations, wars and settlements. Crucial Maps, which concluded in 1937, was the last series of articles. Ganong was the first investigator to employ a critical classification of maps based upon groupings by period and type, although the cartography of Canada's east coast had earlier been introduced by Baron Alexander von Humboldt. Ganong's contributions to cartography are enormous: for example, his reconstruction of Cabot's voyages, while all may not agree with it, is a masterpiece of inductive analysis which will remain a model in historical research; his chapters on Gomez, Verrazzano and Fagundes are still the chief secondary sources on these discoverers. There have been notable additions to the bibliography of discovery and maps since Ganong wrote; recently published works as well as the complete file of Ganong's correspondence with his fellow cartographer, G.R.F. Prowse, were consulted by Theodore E. Layng, Map Division, Public Archives of Canada, in preparing the commentaries which accompany this edition of Crucial Maps. These commentaries, with Mr. Layng's introduction, also provide an interesting sketch of Dr. Ganong and his work. Another important feature of this edition is the index prepared by William Morley of the John Carter Brown Library. In much of his work Ganong was a pioneer, and, while subsequent studies have reached different conclusions on some points, many of his results have seldom been challenged. Students of the present and future will still use and quote from Crucial Maps. Royal Society of Canada Special Publications No. 7

Book Description
This work originated in a Symposium forming part of the programme for Section IV (Geological Sciences including Mineralogy) of the Royal Society of Canada, which met at Queen's University, Kingston, in 1960. Of wide scope, it demonstrates the progress now being made in Canada in the study of its vast area of soils. The papers of this Symposium are unique in that they present for the first time a combined picture of three aspects of soil science–the geological, the pedological (or agricultural), and the engineering (known as Soil Mechanics). The book serves, of course, mainly as an introduction to a large subject, but some more detailed papers give an idea of the depth as well as the wide range of soil studies in Canada today. The contents can be summarized as follows. First come seven papers on Pleistocene geology in Canada, followed by a study of muskeg (which forms half a million square miles of Canada's surface) and one of soil mineralogy. Four papers–one general and three regional–of pedological interest follow. Finally come four papers on soil mechanics: one relating agricultural and engineering soil studies; one discussing geology's influence on the siting and building of airports; a detailed account of the properties of Leda clay; and a general review of the soil problems facing the Canadian civil engineer.
