Excerpt from The Canadian and Ordovician Formations and Fossils of South Manchuria An attempt is made in this monograph to bring into systematic order the facts that have thus far been ascertained regarding the Canadian and Ordovician strata of South Manchuria. For convenience the report is divided into two parts: Part 1 deals with the stratigraphy, containing descriptions of the formations and sections as they occur at the various localities, Part 2 is biologic in scope, comprising mainly descriptions of the new material found by me, although an endeavor is made to present a complete critical review of previous studies. In addition, by request, I have studied a number of Ordovician fossils collected in China in 1915 by Prof. George D. Louderback, of the University of California. As will be noted in the following pages, all the type specimens resulting from my studies are preserved in the collection of the United States National Museum. I began the study of the early Paleozoic strata in the spring of 1924, when I first went to Manchuria. What I learned regarding the Sinian, Cambrian, and Ozarkian beds will be presented in a forthcoming paper written in collaboration with Dr. C. E. Resser. In the spring of 1928, I published in Japanese a preliminary report, entitled "On the Cambro-Ordovician Strata in South Manchuria, " which briefly summarized the results obtained during four years of field work. Since that time my knowledge of the South Manchurian geology has considerably increased through additional field studies, particularly because I have since had the advice and assistance of both American and Japanese geologists. I have corrected herein many mistakes appearing in my preliminary work, and the conclusions presented are naturally somewhat different and, it is hoped, more advanced.
