"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 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 the present 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." - Preface. Part II is "Evidence on Continental Drift from the Arctic and Eastern Seaboard of Canada". All the contributors were Canadian scientists. The theory of "plate techtonics" was only developed in the mid-1960s.
