French-Glenn Live Stock Company records, 1884-1907

Beginning in the late 1870s, Peter French and Hugh J. Glenn purchased large tracts of grazing land in southeastern Oregon's Harney County. Their ranch, which was eventually owned by the French-Glenn Live Stock Company, covered around 140,000 acres, bordering on Malheur Lake on the north and following the Dundar and Blitzen valleys. Some of the land was planted in alfalfa, oats, and barley. It was divided into five parts: the "P" Ranch Division, the Catlow Valley Division, the Diamond Division, the Happy Valley Division, and the Sod-House Division. The company's headquarters were located in Chico, California, and its general manager was F. C. Lusk.

In 1891, the company took out a large mortgage with the German Savings and Loan Society of San Francisco, and in 1898 it entered an additional mortgage agreement with California land speculator Henry Miller. In 1905, the company's holdings were sold to the California and Oregon Land Company, headed by Portland banker Henry Ladd Corbett.
