Records in this collection consist of The Dalles, Portland & Astoria Navigation Company's articles of incorporation and bylaws; records of stock sales, stockholders' meetings, and board of directors' meetings; and a few administrative documents, including the certificate of dissolution. The records reflect changes in ownership, but the collection does not include the company's operational records except as reflected in board meeting minutes. Issues that board members addressed on a regular basis included the purchase, sale, and retrofitting of steamboats; the purchase, lease, maintenance, and sale of wharf sites; hiring and firing captains and other personnel; setting freight and passenger rates; steamboat accidents and related legal issues; and dealing with competitors. There are no records between February 1915 and June 1919. The collection is contained in two bound minute books and three bound stock certificate books, and also includes a small quantity of loose papers that were originally located within the bound volumes. The minutes in the collection were handwritten in ink until 1906, when typed pages were glued into the book. One 1922 letter, probably from the Spokane, Portland & Seattle Railway, was found between the pages of one volume.
