The collection consists of the correspondence and records of the Alaska Livestock and Trading Company, which was based in Portland, Oregon, and operated a sheep and cattle ranch on Unalaska Island, Alaska. Correspondence includes letters to and from legal counsel James Cole and ranchers H. D. Catron, Arthur J. Harris, Jack Handley, Milton Holmes, and W. A. McLaughlin. Additional correspondence pertains to topics such as legislation about a mail boat service, radio installations on Unalaska, and the company's fishing vessel, "Maud." Records include financial documents, work reports, inventories, and documents relating to boats and equipment. Memorabilia and ephemera include historical data about the company and wool samples. Photographs primarily consist of prints and negatives depicting the ranch on Unalaska and its operations. Some materials in the collection predate the incorporation of the Alaska Livestock and Trading Company, and may relate to its predecessor firm, the Western Pacific Livestock Company.
