THE WORLD'S ADVANCE 



HOW DECEPTION IS PRACTICED BY BELLIGERENTS 



French aviators 

 have discovered 

 the fact that 

 guns painted in 

 various colors 

 are quite invisi- 

 ble at high alti- 

 tudes and thus 

 escape detection 

 by the enemy's 

 airmen. Accord- 

 ingly, the French 

 have painted 

 their guns many 

 different colors, 

 as in the instance 

 of this 75-milli- 

 meter field piece. 



This improvised fake gun, 

 consisting of a drain pipe, 

 two cart wheels, a sheet 

 of iron and other odds 

 and ends, was used by the 

 French during operations 

 in the north of France. It 

 caused the Germans to 

 waste a considerable 

 amount of ammunition in 

 an effort to destroy it. 



The British arc pro- 

 viding bases for their 

 hydro-aeroplanes at 

 sea in a very novel 

 way. They are em- 

 ploying steamers on 

 which special landing 

 platforms have been 

 constructed. These 

 ships are so painted 

 that their outlines are 

 not visible to the 

 enemy. In this view 

 is seen one of these 

 steamers and its pe- 

 culiarly painted hull.
