Inyo Development Company Records
Scope and Contents
The Inyo Development Company Records cover the period 1885-1916. The primary subject is the development, manufacture, and distribution of soda products from the Keeler works. Over half of the collection is correspondence. The remainder consists of financial statements, receipts, labor records, soda records, and legal documents. Material is primarily handwritten originals and typewritten copies.
The company records also contain Chinese and Indian payrolls, a transatlantic cable code, and several letters and newspaper clippings about the Owens Valley water project. However, gaps occur in the correspondence and most other records. For example, the company's letterpress book no. 4 was never received. Some documents referred to in the correspondence, such as the ledgers and journals "only temporarily removed from Carson" (June 28, 1913), are not found within the collection.

The Inyo Development Company was formed to evaporate, process, and ship the natural soda found in the brines at Owens Lake, Inyo County, California. Soda works were located at Keeler, on the east side of the lake, where the company owned approximately three thousand acres of clay lands, including town lots; buildings; soda vats; pipelines; furnaces; and other machinery.
H. M. Yerington incorporated this Nevada company in April 1885. Early officers were Yerington, president, and G. J. Ford, later E .B. Yerington, secretary. Stockholders included D. O. Mills, W .E. Sharon, and E. D. Boyle. Superintendents at Keeler included L. F. J. Wrinkle, R. J. Laws, Noah Wrinkle, and L. F. Young. Following H. M. Yerington's death in 1910, the office of president was held by H. H. Taylor, and in 1911 by John. F. Cannon. In 1913 A. B. Davis became vice-president and general manager. These last three officers were based in San Francisco, California. The material ends with correspondence dated November 1916, at which time it appears the company was still active.
In 1885 the Inyo Development Company began by producing crude soda for the borax manufacturers. In the period 1898-1899 the company also started producing soda ash which was sold to glass, soap, and other manufacturers. The company was represented by a soda agent in San Francisco and at various times employed chemists to experiment with processes and equipment.
