The Pratt and Ferris Cattle Company was formed in 1879 by partners James Hervey Pratt, Marshall Field, Levi Leiter, Robert M. Fair, and Cornelius Ferris, with Pratt as the general manager of ranching operations. The company operated the Ucross ranch on Clear Creek in Johnson County, Wyoming, and the P.F. Ranch in Goshen County, Wyoming. Pratt's grandsons Jerome Pratt Magee and Wayland W. Magee were involved in operations of the P.F. property, and Wayland W. Magee became manager after the death of James H. Pratt in 1910. Magee served as manager from Bennington, Nebraska, where he also managed the Summer Hill Farm.
