"Very possible," agreed Blake. "Labenstein, of course, would be with the German forces, and since Secor is a traitor he would be there also. Of course it may not have been those fellows, but some other two men who had learned through their spies that we were here taking pictures and wanted them for their own purposes."

"The question is, can we get them back?" put in Charlie, scowling in the direction of the Germans.

"That's only one of the questions," observed Blake. "The main one is, where are the films now, and where did those fellows go with them?"

"Maybe I can help you out there," put in the soldier. "I saw those two fellows heading that way, down in that depression, and they certainly carried some sort of flat, square boxes under their arms."

"What's down in there?" asked Joe eagerly.

"Well, it was a machine-gun station, and old Fritz certainly played hob on our boys with it," answered the sentry. "But we wiped that out the other day, though I guess the dugout is there yet, or whatever is left of what they used to house their barker in. The two fellows I saw were heading for that spot."

"Is that between the lines?" asked Joe.

"Just about, yes, though there aren't any of our trenches, or theirs either, near there now. What trenches there were have been knocked into smithereens. That's No Man's Land down there. It belongs to whoever can keep it, but just now nobody seems to want it. I'm here to report if there's any movement on the part of Fritz to take up his station there again."

"As it is now, could we go down there?" asked Joe eagerly.

"Well, if you wanted to take a chance, I s'pose you could," answered the sentry slowly. "I wouldn't stop you. You don't belong to the army, anyhow, and we've been instructed that you're sort of privileged characters. All the same, it might be a bit dangerous. But don't let me stop you."
