“ Doyle's literary work left him leisure for other interests besides those of local administration. He was a volunteer from the commencement of the volunteer movement; he was in the rifle corps as a boy at Eton and as an undergraduate at Oxford, and he took up rifle shooting with enthusiasm. He accompanied the Irish team which visited America in 1874; he shot in the Irish eight for the Elcho shield in 1875, and made the top score for the team, (147 out of a possible 180) , and he was for many years adjutant of the Irish eight. ”
