This is another sign from one scout to another and means: "I have returned home."
The "blaze" on the tree trunk and the two stones, one on the other, are simply to show that the scout is on the right trail.
The other three sketches are to show the direction in which the scout should go. The arrow is marked on the ground. The upper part of the sapling or bush is bent over in the direction which the scout should take, and the same is the case with the bunch of grass, which is first of all knotted and then bent.
SPIES IN WAR TIME.
The Japanese, of course, in their war with Russia in Manchuria made extensive use of spies, and Port Arthur, with all its defects of fortification and equipment, was known thoroughly inside and out to the Japanese general staff before they ever fired a shot at it.
In the field service regulations of the German army a paragraph directed that the service of protection in the field—that is to say, outposts, advanced guards, and reconnaissances—should always be assisted by a system of spying, and although this paragraph no longer stands in the book, the spirit of it is none the less carried out.
The field spies are a recognised and efficient arm.
