Contains letters from Maria Campbell Smith written to her son, Charles Evelyn Smith, while she lived in Europe, New York State, and Washington, DC. Letters discuss health, activities, marriages, and deaths of family members and friends, and social activities and gossip of the place she happens to be staying. She also comments on Charles’ attempts at business, his love affair, and his marriage to “Sue” and their eventual troubles. But the most consistent topic throughout is Charles’ gross mis-management of the money she has entrusted to him, her desperate need for him to send her money to live on, and real estate dealings he is supposed to be managing for her. Despite these difficulties, her letters are always addressed, “My dear Charley.”
