INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document hBve been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques it provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on die film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again - beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced. * 5 .

Sumner Adviser Department of Anthropology I ACKNOWLEDGMENTS i | Gtaduate studies, especially dissertations, are impossible without the assistance and encouragement of many people. My special thanks to Drs. Bernard Walles and Major McCollough, who got me started, and to the faculty of the Anthropology Department of the Oliio State University, who kept me going. I am especially grateful to the Department Chairpersons at Ohio State during my study there, Drs. T. R. Williams and Erika Bourguignon, who encouraged and sup ported my largely independent program of study. Many individuals contributed to my understanding of lithlc studies in archaeology, and 1 thank them all. Most important among tliese is Mr. Don Crabtree, Idaho State University Museum Associate, Pocatello, Idaho. Not only is he an inspiration personally, but his skills and understandings have been generously shared with many students, and I consider myself fortunate to be among them. The research on which this dissertation is based was made possible by Dr. R. S. MacNeish of the Peabody Foundation for Archaeology, Andover, Mass., and director of the Ayacucho Archaeological-Botanical Project. Funding for that project was provided chiefly by the National Science Foundation. Dr.. R. K. Vierro, Northwestern University, Ayacucho Project statistician, was extremely helpful in organizing and processing the basic data. The assistance of my reading committee, Drs. John Friedl, William S. Dancey, and especially my adviser, Dr. W. M. Sumner is gratefully acknowledged. Their patience and encouragement were indispcnsible. ii VITA June 25, 1936 .........

INTRODUCTION At least two million years ago people first learned that by applying force to a piece of stone in certain ways they could pre- , diet the fracture of the stone and produce a sharp edge or point which was more useful than the stone In Its natural condition. Gradually through trial and error and through fortuitous accident they learned to control the variables involved in this fracture process until, by the end of the Paleolithic, they were able to make a wide range of varied and complex flaked stone Implements.
