The Sadie and Hampton George Papers (1874-1948) consist primarily of the incoming and outgoing correspondence of Sadie Kiel George and her husband, Hampton George, regarding proposed land and mineral rights sales. The collection also includes some personal correspondence, and two of the most significant letters in the collection deal with the deaths of brothers William and Edward Kiel, Sadie's uncles, who were found dead at the Kiel Ranch in October 1900. Also included in the collection are receipts, cancelled checks, tax notices, mining claims, and land deeds.

The George Ladd Papers are comprised of a scrapbook dating from 1903 to 1906 that documents the final years of George Ladd, who was involved with the Bullfrog Mine in Rhyolite, Nevada. The scrapbook contents include personal correspondence, certificates of assays, telegrams, mining purchases, bank deposit slips, and correspondence between Ladd and the Bullfrog Mining Company.
