Crete foundations for them to stand upon 

 before they can be fired. But the Ger- 

 mans foresaw this long before the war, 

 and laid theirplans 

 accordingly. 



They examined 

 all the country 

 over which they 

 were likely to 

 fight, both in Bel- 

 gi u m and in 

 France, and wher- 

 ever they saw good 

 positions for guns 

 they built founda- 

 tions and emplace- 

 ments for them. 

 This was done in 

 time of peace, and 

 therefore had to 

 be done secretly. 

 In order to divert 

 suspicion, a Ger- 

 man would buy or rent a farm on which 

 it was desired to build an emplacement. 

 Then he would put down foundations for 

 a new barn or farm building, or — if near a 

 town — for a factory, and when these were 

 complete, he would erect some lightly con- 

 structed building upon it. There was 

 nothing to attract attention or suspicion 

 about this, and numbers of these emplace- 

 ments are said to have been made before 

 war began. When war broke out and the 

 t roops arri\ed on the ground , the buildings 

 were hastily pulled down and there were 

 the emplacements all ready for the guns.

A sketch of a triangular fort was trans- 

 formed into a stained glass window design, 

 with certain of the decorations signifying 

 the location and sizes of guns 



gaining na\al or militar\' details. Conse- 

 quenth- officers are often employed to 



obtain such information in peace time 

 as well as in the theater of action in war. 

 But with them, and especially with those 

 of Germany, it is not easy to find men 

 who are sufficiently good actors, or who 

 can disguise their appearance so well as 

 to evade suspicion. Very many of these 

 have visited England's shores during the 

 past few years, but the\' ha\e generally 

 been noticed, watched, and followed, and 

 from the line taken by them in their 

 reconnaissance it has been easy to de-

 in their plans. 



Catching a Spy 



Spy-catching was once one of my 

 duties, and is perhaps the best form of 

 education towards successful spying. I 

 had been lucky enough to nail three and 

 was complimented by one of the senior 

 officers on the Commander-in-Chief's 

 stafi". We were riding home together 

 from a big review at the time that he was 

 talking about it, and he remarked, "How 



The sketch on the left was made, giving 

 all the particulars wanted. To bury it 

 in such a way that it could not be recog- 

 nized as a fortress plan if the spy were 

 caught by the military authorities, it was 

 turned into a sketch of a moth's head. 

 Underneath in the note-book was written: 

 "Head of Dula moth as seen through a 

 magnifying glass. Caught 19.5.12. Mag- 

 nified about six times size of life." 

 (Meaning scale of six inches to the mile.) 



do you set eibout catching a spy?" I 

 told him of our methods and added that 

 also luck \"ery often came in and helped 

 one. Just in front of us, in the crowd 

 of vehicles returning from the review- 

 ground, was an open, hired Victoria in 

 which sat a foreign-looking gentleman. 

 1 remarked that as an instance this was 

 the sort of man I should keep an eye 

 upon, and I should quietly follow him 

 till I found where he lodged and then 

 put a detective on to report his moves.
