From outline: This hook is a review of the present state of knowledge of the general structure of the pre-Cambrian rocks of the United States and Canada. The material contained in the historical chapters is of two kinds: Summaries of all articles pertaining to the subject considered, and summaries of the conclusions which appear to be established. The first represents the substance of the literature; the second brings together the important ascertained structural facts, and often times becomes a more or less extended discussion. The final chapter covers the same grounds as the historical chapters for the various pre-Cambrian in general successions proposed by different authors, and also contains a discussion of results and the principles upon which they are based. Within the chapters, individual districts or regions are given separate sections, and the summary of literature for each is arranged in chronological order.
