Abstract

To many of the delegates to the Twelfth International Geological Congress who listened to the papers and discussions on Pre-Cambrian problems and who afterwards took part in the Canadian transcontinental excursions into regions where the ancient elastics were displayed in infinite variety, the most valuable feature perhaps, was the field evidences of the amazing taxonomic possibilities which on the American continent the Pre-Cambrian sections were opening up. Few of the travelers had ever seen so deeply into the oldest stratified rocks in so short a time, under such favorable circumstances, or under happier guidance. Some of the participants in the proceedings, preeminent in other fields of stratigraphic endeavor, seemed to see in this old American complex exactly the counterpart of conditions that were presented a century ago by the Primary (Paleozoic) rocks when they were awaiting the magic touch of English geologists to unfold the then inextricable maze.
