Later in 1915, Lane's mother visited San Francisco for several months. Together they attended the Panama-Pacific International Exposition. Details of this visit and Wilder's daily life in 1915 are preserved in Wilder's letters to her husband in "West from Home", published in 1974. Although Lane's diaries indicate she was separated from her husband in 1915, her mother's letters do not indicate this. Lane and her husband are recorded as living together with him unemployed and looking for work during her mother's two-month visit. It seems the separation was either covered up, or had not yet involved separate households.
