Records primarily related to Hiram A. Andrews’ ranching operations at the Davis Ranch at Horse Creek, Laramie County, Wyoming. Overall, the collection provides information and perspectives on an early 20th century livestock business, and, to some extent, the livestock industry in general.

Also included in the collection is a folder on the Plains Automobile Company of Cheyenne. Andrews was on the Board of Directors for the Company, along with William B. Ross.

Correspondence and a court record also provide information on a land dispute involving Andrews.
