The materials comprising the majority of the collection are minutes, correspondence, and financial records; some of these materials are bound in two ledgers. In general, both the loose minutes, and those in the two ledgers, discuss accounts payable and receivable, applications for membership, and repairs, improvements, and extensions to be made to the line. The “Double Entry Ledger” also contains a membership list of both charter co-partnership members, and those added later by vote. The minutes that end in the Double Entry Ledger on page 50, continue in the “S.E. Ledger” on page 110.
The agreements in the collection primarily concern the extension of Pacific Telephone and Telegraph Company's line out of Rainier, and include a Permit for Attachments (to the line), a map of telephone lines and contacts, a “Crossing Agreement” with the Bonneville Power Administration (BPA), and an associated tower location map for BPA’s St. Johns-Astoria line.
The majority of the correspondence in the collection concerns requests for membership in the partnership or the relinquishing of membership. Also includes are letters from the Pacific Telephone and Telegraph Company regarding delinquent payments and workers’ compensation coverage. Of special note are a series of letters from the War Production Board, dated between December 1942 and January 1943, regarding a request for “priority assistance” in order to purchase galvanized iron wire.
Financial records include bills and receipts to members/partners, and Pacific Telephone and Telegraph Company; a contract between the partnership and George Bartlett to rebuild a portion of the line; State Tax Commission Certificates of Assessment, and Annual Reports (1938-1939, 1960); and information regarding tax exemptions for “small telephone lines.” Both ledgers also contain the accounts of members, including payments on account and assessed maintenance costs.
