"You'll do," was the reply. "Got a nasty knock on the head, but your skull isn't damaged--just a scalp wound. We'll wash you up a bit and send you back. Here, orderly, some water and bandages." Jimmy closed his eyes and gritted his teeth. The mere touching of the wound on his head, to wash and bandage it, was most painful, but he did not utter a sound. Then he seemed to doze off, and when again full consciousness came to him it was to open his eyes in a temporary hospital. He was lying on a cot under a screen of bushes--a camouflaged place, to prevent, if possible, the Huns from dropping bombs from airships on this oasis of mercy. And it was while lying on the cot, feeling more comfortable now that his head was bandaged, that Jimmy saw a squad of soldiers from the signal corps passing along the road. They had been ordered to the front to establish better communications, now that the German raid had been repulsed and the Boches were being forced to retreat. As Jimmy looked at two men in the signal squad carrying a black box, which he recognized as one containing part of a wireless outfit, Jimmy felt a queer sensation. "Why, I know those two fellows!" he told himself, as his eyes followed the marching twain carrying the black box. "I know them, though this is only the second time I've seen them, as far as I can tell. The other time was in the dugout. Those are the two army fellows who were talking to the two civilians. And now to find them in the signal corps! What does it mean?" CHAPTER V BATTLING ONWARD Well might Sergeant Jimmy ask himself that question. For a moment he feared lest the injury to his head had caused his brain to wander so that he "saw things." But as he looked about on other sights--noted wounded men being brought in, saw fresh fighters rushing up to the front, to be ready if called on--and when he again looked toward the marching squad of the signal corps Jimmy felt sure that his brain was normal. And there was no doubt, in his mind, of what he saw. He looked again at the two doughboys who had attracted his attention. They were in strong sunlight, and Jimmy was sure he could not be mistaken. "They're the same two who were in the dugout talking to the two men in civilian clothes," murmured the wounded lad. "And those two civilians might be almost anyone. I only hope they weren't German spies! That would be fierce--to have two of our men meeting German spies secretly. But hold on--wait a minute. There may be another angle or twist to this game." Jimmy raised himself on his elbow and looked after the disappearing signal corps squad. The two men carrying the black electrical box were in the rear now.
