The thing came too quickly for warning. Suddenly from above the inhabitants of the hole, with whom Angus was consuming a midday glass of port, was heard the voice: "It must be somewhere about here, sir, I think." The voice was right—it was.
They came through in a phalanx of fire, and descended abruptly on the detachment below. It was a magnificent compliment to the work, but it was unfortunate that the General should have been the one to consume the nettles. However, I have always thought that Angus's voice of disgust as he contemplated the wreckage of his screen did not improve matters.
"The door," he remarked, with painful distinctness, "is full of possibilities." With that he left.
I trust the moral of my digression is obvious. . . . Having then, in a few well-chosen phrases, discussed one type of camouflage, I would pass on and lead the thirster for information still farther into the by-paths of knowledge. Just as there are many and divers types of deceit, varying from that which conceals what is, to that which exposes what is not—involved that last, but think it out—so are there many types of camouflage. And the particular one with which I am concerned, deals with a tree.
On a certain slight eminence in what was otherwise a flat and dreary outlook, there stood the stump of a tree. It was a tired stump, strongly reminiscent of the morning after. It had had a hard life, and much of its pristine glory had faded. No longer did the sprightly sparrow chirrup cheerfully to its young from leafy branches; no longer did cattle recline in its shade during the heat of the day. It was just a stump—a stump complete with splinters.
Its sole claim to notoriety lay in its position. It commanded a view of the German lines which was not to be had elsewhere; in fact, from the eminence on which it stood you could obtain the only good observation of the opposite trenches in that particular sector of the line.
It was the Brigade Major who first suggested the idea in the fertile brain of the C.R.E. of the Division, who happened to be talking to him at the moment. They were in the support line trenches, and close to where they stood, the tree—gaunt, repulsive and toothpicky—raised its stunted head to heaven.
"What a pity that tree ain't hollow!" ruminated the Staff officer thoughtfully. "Splendid view from it of the Huns. Can't do anything in that line, can you, Colonel?"
The C.R.E. thoughtfully considered the proposition. "Afraid not, old boy," he answered after a few moments' deliberation. "Bit of a job hollowing out a tree. All the same, you're quite right. It would make a great O.P."
"Why not make another down in your yard, and put it up instead?" The Brigadier joined in the discussion. "We must have better observation in this sector if we possibly can."
