Among the multitudinous means employed by German female agents in
France is the insertion of small advertisements in the Parisian papers
proposing an exchange of correspondence with British officers at the
Front. Until a stop was recently put to this practice, as the result of
an inquiry at military headquarters, I frequently saw advertisements
of this sort in a daily published in Paris. Here is a specimen of one
announcement:--
"Refined Parisian lady wishes to exchange correspondence with cultured
person at the Front, to improve knowledge."
