In time of peace, prepare for war, is the paramount duty of a nation; and particularly is it so of the naval part of it; and in no way can a naval officer serve his country and the service so well as to keep his mind and body in readiness for the emergency of war.
Were I to give advice to an officer on this subject I would say, read and study. Idleness in a naval officer soon makes him rusty and of little value to his country or the service. Commodore Roe, in his admirable work, says: "The naval officer is always at school. The very routine of his profession changes day by day. Progress and invention changing, keep him ever learning new things, solving new problems. To keep pace with the progress of his profession he must be a scholar as well as a laborer."
