See L'Homme contemporain du mammouth a Spy (Namur, 1887) ; G. de Mortillet, Le Prehistorique (pgoo); Sir A. Keith, Antiquity of Man, znd ed. (1925).
not wearing a disguise is not a spy, though he may be found within the zone of the hostile army and though his object may be to obtain information; nor are soldiers or civilians spies who cross enemy lines openly carrying messages. This applies even to per sons sent in balloons for the purpose of carrying despatches. A spy must not be "punished" without previous trial (art. 3o), nor can he be treated as a spy if he is captured after he has rejoined his army. He must then be treated as an ordinary prisoner of war (art. 31).
The term "spy" is applied also to those who in time of peace secretly endeavour to obtain information concerning the forces, armaments, fortifications or defences of a country for the pur pose of supplying it to another country.
