Letters are primarily to White's mother, Alexina Black Mease White, his father, Richard Grant White, and his wife, Bessie Springs Smith White. The volume of White's letters from Mexico documents an extended trip he took with his elder brother, Richard Mansfield White, to prospect. Also included in the last volume is a letter to White from H. H. Richardson, dated February 22 1878, acknowledging White's resignation from Richardson's firm. Each original manuscript letter is followed by a typed transcription by Lawrence White, unless otherwise noted.
