The Works Progress Administration collections include , under Cultural History, New Mexico, manuscript contributions by Thorp. These include No. 164, Stories, and Nos. 172, 176, "Cowland." Another item of interest in the collection is No. 167, Western Songs and Verses, which I believe contains Thorp's(?) "On the Frisco River" and possibly other contributions. An elibrary copy is available in the Libraries of the University of New Mexico, Albuquerque.
