In one of the road and river reports I read these words, "Data given by the Belgium government railroad cabinet on January 1st, 1912." Thus was the English officer assured of its accuracy. These are the figures that were given for the use of British troops in Belgium. Locomotives 4,233 Coaches 8,001 Baggage cars 2,714 Goods wagons 86,562 Special wagons, (for oil, etc.) 2,418 [Illustration: _Photographs obtained by Mr. Fox from the originals in the German War Office._ Aviator's key map prepared by English war office.] I think I have quoted enough material from these wonderful books to show the thoroughness with which the British soldiers were ready to fight in Belgium. Now the Germans have shot down many British aviators and on one of these men they found a book. It had the same brown paper cover as the road and river reports. It was of the same convenient pocket size. It had the same serial letter A for army, and it was numbered 1775. I saw this book in the General Staff. It is "A report on Belgium south of the line Charleroi, Namur, Liége and Brussels for aviators." I photographed pages 3, 6 and 20 of this book. Page 3 which began the information gave some interesting generalizations on the whole district. On page 6, dealing with Namur, I read that English aviators were told that the glaces of Fort d'Emine provided unlimited open cultivated ground suitable for landing purposes. In other words they were advised by the English War Office that it would be safe to land under the very guns of this Belgian fort. If they were flying in the Liége district they would read on page 20 that five miles out on the east of the Aywaille road they could prepare a very good landing place on grass by the simple removal of some wire fences. They were assured that from the south they would be completely covered by the Belgian guns of Fort d'Emibourg. In other words the British War Office was so well prepared, knew so exactly what it was doing that in July of 1914 it issued a book advising its aviators how to land in places where they would be covered by Belgian forts. A map accompanied this aviation book. Let us see how this map was used. Examine this map around Liége. You will see numbers running from 89 to 94. An aviator flying over Liége consulting his map knows that each of these numbers has to do with a landing place. Let us suppose he selects 92.
