Prowers County, Colorado, investigated fifty cases of mouth-to-mouth propaganda, a notable case in its annals being that of a German Lutheran minister who refused to answer the question as to which side he wished to win the war. It did not take him long, however, to realize that he had made a blunder. He asked for time. The next day he declared very promptly that he wanted the United States to win. He was instructed to prove this by preaching and praying it in private as well as in public, which he agreed to do. (p. 449)
