It is a pleasure to acknowledge all those persons who have aided in the preparation of this volume. Friendly help came from Robert E. Lange of Portland, Oregon, who was always ready to answer Columbia River queries. Gladys Watkins Allen (Alton, Illinois), Emilie W. Betts (New York City), William P. Sherman (Portland, Oregon), Nelson S. Weller (Piedmont, California), and Lyle S. Woodcock (St. Louis, Missouri), provided financial assistance to the project, as well as personal goodwill. Financial aid also came from the National Endowment for the Humanities, an independent federal agency, and from the Lewis and Clark Trail Heritage Foundation, whose many members have continued their support of this endeavor in so many ways.
