The correspondence, nearly all of which is to other writers, discusses the work both correspondents have in progress and their reactions to various plays. A letter to Ellis discusses Bax's Victorian upbringing; the Kilgour correspondence is centered around the Playwrights' Club; the Lafitte Cyon letters make frequent mention of Meum Stewart. The manuscript genealogical materials trace the Tingle and Lea branches of the Bax family; their compiler is unknown.
