The George W. Arnold Letter is dated to 1870 and contains a handwritten letter from Arnold to his uncle Gideon. The letter is a brief account of Arnold's life as a miner in Pioche, Nevada. The collection also contains a typed transcript of the letter's content.

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.
