Read's poem "Drifting," in which she displayed a rare ability to modulate her voice; specimens of the reading by a country school class; two scenes from Henry VIII; Queen Katharine of Arragon's plea in court, and her speech when near death; remarkable portraits of Charlotte Cushman; an impersonation of Oscar Wilde, whom, by the way, she commended for having brought some good ideas to this country; an imitation of a Yankee spinster giving her ideas upon training boys; and an address "newspapers" a la T.
