Acknowledgments. Field work adds to museum collections and museum collections provide time depth and context for future field work. I thank those who care for the collections that contain “Adena” and “Hopewell” cultural remains and who have always made their collections accessible for study. In particular for materials in this publication I extend my thanks to Bradley Lepper and the staff of the Ohio Historical Society for access to the papers of James Marshall soon after they became part of the Society’s collections. It is there that I first learned of the paper by R.B. Holt. Jonathan Haus and Jamie Kelly of the Field Museum care for a major Ohio Hopewell collection acquired during excavations intended to provide exhibits for the Anthropology Section of the 1893 World’s Columbian Exhibition held in Chicago.. I thank them for their assistance. Thanks to Genevieve Fisher and Jessica Desany of the Harvard Peabody Museum for assistance in obtaining copyright permission for the use of photographs of the copper effigy pipe (76-7-10/8993, copy right 2005 President and Fellows Harvard College) and copper beads (76-7-10/8992, copyright 2011 President and Fellows Harvard College). And thanks to Kit Wesler who answered technical questions as I learned the technical pitfalls of a new presentation format and the perils of the inter-net.
