In most of the letters Carney addresses the Irish Labour leaders about the situation of Jim Larkin, who was imprisoned in the United States at this time. He urges them to write to Larkin more frequently, to send him Irish newspaper clippings and to keep him up to date about Irish affairs. He is highly critical of the stance of Eamon De Valera, who was visiting the U.S. at this time, but says that he will refrain from comment so as to avoid a public disagreement. He makes reference to other disputes also and mentions Delia Larkin in one letter.
