"Lead on, old scout," said Billy. "But first we must wedge this door up a trifle, so as to be able to open it easily when we come back."
"Right you are!" said Frank. "When we do come back we may have to come in a hurry for all we know, and we want to be able to lift this up in a jiffy."
They hunted around until they found a small slab of stone which they wedged under the door, after they had dropped down into the s.p.a.ce below. Then, with Frank in the van, with his flashlight sending its rays ahead of them, they ventured slowly into the unknown, feeling their way with the utmost caution.
The stone floor was uneven and damp, and at times they stepped into pools of noisome water that was covered with green sc.u.m. The sides of the narrow pa.s.sages were covered with mold, and the air was heavy and offensive.
Suddenly Frank stepped back with a sharp exclamation, and at the same instant there was a squeal, and a gray form scurried away into the darkness.
"A rat!" he murmured to his friends behind him. "I stepped fairly on him. A mighty big fellow he was, too."
They went on a little further, keeping close together, for there were several pa.s.sages that branched off from what seemed to be the main one, and if they became separated it might be difficult for them to get together again, especially as Frank was the only one of the trio who had a flashlight.
And now their ears were a.s.sailed by soft patterings and shufflings that seemed to increase in number as they progressed. Their eyes caught certain red points that flared like sparks and then vanished, only to reappear. It was as though a host of eerie things were keeping tab on their movements, and after a while this silent mustering of unseen watchers got on their nerves.
Billy, who came last, was pa.s.sing one of the pa.s.sages that branched off to the left when he thought he caught a glimpse of light. He went into this side pa.s.sage for a few steps to make sure, and verified his first impression. There, sure enough, was an electric bulb, on the opposite side of which he could see the outline of a door.
He was hurrying back to tell his comrades what he had seen when he heard an exclamation from Bart that quickened his steps still more. Bart"s right hand was holding on to his left, and in the light that Frank had directed on it he saw that the hand was bleeding.
"It was a rat," Bart exclaimed wrathfully, as he nursed his wounded hand. "The beggar jumped straight at it. It feels as though he"d made his teeth meet through it"
Billy whipped out his handkerchief and was binding it around his comrade"s hand, when a gray form sprang from the darkness and fastened its teeth in his trousers leg just grazing the skin.
Frank made a kick at it, but as he did so, his foot slipped on the damp stone and the flashlight flew out of his hand, leaving them in utter darkness. He stooped to try to find it, but his hand touched a furry coat and he drew back just in time to escape a savage snap.
Then as if by magic those red pin points, that they now knew were eyes, seemed to spring up from every direction. There were rats everywhere, an army of them, rats ahead of them and rats behind them, gathering to oust these human intruders from their domain.
Singly they were contemptible opponents, but now they had the strength that came from numbers, and they knew it.
And the Army Boys knew it too. For an instant panic gripped at their hearts. The next moment they had pulled themselves together.
"Back to the trap door, fellows!" said Frank tensely. "Fast, but not too fast. Don"t run. And don"t shoot, or we may hit each other. Draw your revolvers and club them off with the b.u.t.ts."
They retraced their steps as well as they could in the darkness.
The rats knew that they were retreating, and they grew bolder.
Again and again they fastened themselves on their arms and legs, and had to be beaten off with the revolver b.u.t.ts. All the boys were bitten many times, and it seemed to them that they would never come to the end of the pa.s.sage alive. But none of their a.s.sailants reached their throats, although one had to be knocked from Billy"s shoulder, and at last the nightmare journey ended when they stumbled against the steps that led to the trap door.
Frantically they heaved the door up and clambered out and sank down on the ice covered ground, spent and out of breath and utterly exhausted.
CHAPTER XVIII
THE CRITICAL MOMENT
For a time the Army Boys sat there, panting and gasping from their unwonted exertions, yet filled with a deep thankfulness that they had won through as well as they had.
At length Frank gave a short laugh that had in it little trace of mirth.
"Three husky doughboys of the American Army put to flight by a horde of rats!" he exclaimed.
"All the same, they"d be picking the bones of those same husky doughboys if we hadn"t vamoosed," defended Billy. "Gee! it seemed to me that there must have been millions of them."
"I know now how that Bishop Hatto, or whoever it was, felt when the rats were after him," put in Bart. "If we"d only had some clubs with us we might have had a chance."
"Well, they made us show our backs, and that"s something the Huns were never able to do," said Frank. "But I guess we"d better get back to the barracks and cauterize these bites. I don"t know how you fellows made out, but I"ll bet they bit me in twenty places.
I"m bleeding fiercely."
"Same here," echoed Billy.
"I feel as though I were one big wound," said Bart lugubriously.
"But say, fellows, don"t let on what we"ve been up against or the boys will guy us to death."
"And to think we"ve been to all this trouble only to find that we"d stumbled into a sewer," said Frank disgustedly. "That"s what it must have been, guessing by the smell."
"Oh by the way!" exclaimed Billy, as a thought struck him. "I meant to tell you fellows, but the fight with the rats put it out of my mind. There was an electric light in one of those pa.s.sages."
Frank, who had gotten to his feet and started to walk away, stopped as though he had been shot.
"What"s that?" he demanded sharply.
"Fact," replied Billy. "I could see it plainly, and behind it I saw the outline of a door. I started to tell you fellows about it, and then I heard one of you shout and I didn"t think of the thing again till this blessed minute."
"Well, that certainly was hard luck!" exclaimed Frank bitterly.
"Ten to one that"s the clue to the mystery. My hunch wasn"t a false alarm after all. I"ve a good mind to go back right now and finish the job."
"Not on your life you won"t!" said Bart decidedly. "Not if Billy and I have to hold you back by main force. Why, boy, you"re crazy.
Those rats have tasted blood, and they"re full of fight. And then, too, we haven"t any clubs to beat them off. It would be sheer suicide to go in there again to-night."
"Bart is right," acquiesced Billy. "Some other night perhaps when we"re in shape for it, but not now. Come along, old man, and use your common sense."
Frank knew in his heart that his friends were right, but it galled him horribly to defer the adventure.
"Well," he agreed reluctantly, "we"ll call it a night"s work and let it go at that. But I"m only giving it on the promise that we"ll try it again. We"ve never let anything in Hunland get away with us yet, and it"s too late to start it now. If I live I"m going to get to the bottom of this."
"Sure thing," agreed Bart. "We"re just as keen to clear it up as you are. But this isn"t our lucky night. Let"s light out for the barracks and fix up these bites."
They made their way back and slipped in as un.o.btrusively as they could, and after they had cauterized and dressed their wounds they sought to forget their disappointment in sleep.
The next day found them stiff and sore, but this feeling wore off as the day progressed, and when night came they forgot everything in their eagerness to be on the march to hunt for their missing comrade, who had hardly for a moment been out of their thoughts.
The plans for the expedition had been carefully mapped out. The detachment was to travel by lanes and byroads as much as possible, and under the cover of darkness they hoped to avoid observation and comment. Their chief hope of success lay in taking the enemy by surprise, and every precaution was observed to prevent any miscarriage of their plans.
"Say, fellows, if we can only have the old scout with us by to- morrow night!" exclaimed Frank, turning to his two comrades, his eyes alight with eagerness.
"Wouldn"t it be bully?" cried Bart.
"I"m betting that we shall," said Billy hopefully. "That is, if he happens to be the prisoner that d.i.c.k was telling us about. Of course that"s only a guess."
The order came to fall in, and with Lieutenant Winter at the head the expedition started out on its long hike. The men moved along in loose formation, and all loud talking in the ranks or unnecessary noise was put under the ban.
