# Air Service Boys Flying for Victory/Chapter 21

CHAPTER XXI
AT THE OLD CHATEAU
The air service boys had no difficulty in retracing their steps, especially since Tom, with his usual caution, had been careful to remember the spot where the main road was joined by that coming from the country cemetery.
Once again they made their way past the ghostly looking stones.
"I can see our boomer now, Tom!" Jack cried, as if he had been a little afraid that something had happened while they were absent, and that they would find the airplane missing.
"You want to be mighty careful of that stuff," his chum warned him, as Jack stumbled over some unnoticed object, and only retained his balance by a supreme effort.
"That's a fact," mumbled the other. "Especially as there's no more where this lot came from. I attended to that, all right. But here we are, and now to get the holes plugged up."
​"At last my time to make use of that little outfit has arrived!" Tom exclaimed. "I've carried it for months, thinking I'd need it badly some day or other. Well, that time is on us, and this repays me for all my trouble. Set that pail down, and be ready to lend a hand, Jack."
He fumbled in a pocket of the body of the plane, producing a small roll, which, upon being opened, disclosed several plugs of soft wood, such as might easily swell if moistened. There was also some wax, the kind fruit growers use in grafting new scions on old trees.
Tom carefully examined one of the holes in order to learn its exact dimensions.
"Just as I expected, it's perfectly round in shape, which makes it easier to plug up," he announced, pleased with his discovery. A minute later he had fitted one of the wooden pegs in tightly. Then he used the wax, which was just hard enough for his purpose.
"That one is finished, and I think it will hold fairly well," he remarked, somewhat to the surprise, as well as delight, of his companion, who had anticipated that it would take much, longer.
"You're a sure-enough wizard, all right, Tom," was his gratified comment. "Why, you're getting things put through in a jiffy. But I hope there isn't any danger of the petrol acting on the wax, and causing a quick leak."
​"I've tested it, and feel certain it will hold for an hour or so, anyhow, Jack. And by then we ought to be back in camp."
"Will, if we have any luck at all," asserted Jack.
"Now I'll get busy on the other hole," continued Tom. "Though that isn't so important, as it's at the top of the reservoir. Still, it might be just as well to close it up in order to avoid waste. Besides, there's always danger of an explosion if your tank sprinkles this deadly stuff around."
Jack took occasion to step aside to where he could look up between the trees and glimpse the dimly seen chateau, knowing now just where to look for it. When he came back he had information to impart that he thought would please Tom.
"Still a blaze up there, Tom, showing that the conference isn't over yet."
Presently Tom straightened up.
"That is all done," he announced, in a satisfied tone. "And done well in the bargain. Now bring along your gas, and be careful how you pour it in. By good luck I've got a funnel that can be used. I'll hold it while you start things going. Jack. Easy now, no hurry; every drop is precious remember!"
The contents of the little pail was presently successfully transferred into the reservoir which Tom had so adroitly mended after its rough ​treatment at the hands of the Huns who worked the "Archies," or anti-aircraft guns.
Tom gave a sigh of relief when that part of the proceeding was finished. He had entertained a little fear that Jack, in his haste to get things over with, might spill the precious fluid on which so much depended.
Afterwards Tom examined for himself, and was satisfied.
"Not a sign of a leak yet, and there isn't going to be either," he told his companion, not exultantly, but nevertheless with confidence that a belief in the staying qualities of his own work justified.
"Now we can get going on the second part of our programme," Jack returned, as he once more cast a steady look toward the height on which the chateau stood.
"No need of staying here another minute, Jack. Nobody knows just what's going on over there, or how long those visitors mean to stay."
"All the same," the other air service boy mentioned, as if casually, "General von Berthold is giving his guests a regular jolly time of it. In these days of war I reckon the Huns are missing pretty much all their favorite drinks, and when they do strike a cellar full—and I guess they have it here—it's like drawing teeth to pry them loose. Listen, don't you hear them at it now?"
​Indeed, it would have been impossible for any one with ordinary hearing, when within half a mile of the chateau, not to have heard what Jack referred to. Some one was singing at the top of his voice, and a heavy voice he had in the bargain. He kept time with the rhythm of his song by repeated poundings on a table with what might have been a stein.
"Well, what nerve!" ejaculated Jack. "It's the Watch on the Rhine he's trolling, as sure as you live!"
"And with the whole bunch joining in the chorus in the bargain," added Tom, as the burst of singing suddenly grew stronger in volume. "They utterly refuse to believe they're whipped flat, even with the Americans ready to step over into Germany and mop 'em up all the way to Berlin."
"Huh!" snorted Jack disdainfully, "we'll soon be the ones keeping watch on the Rhine, see if we'll not. Only sillies with their wits flabbergasted by pride would shut their eyes to the handwriting on the wall. But I'm not sorry, for if they keep on enjoying themselves in that way we'll find it an easy job to roam all over the old shack, looking for Helene."
They were walking briskly along while exchanging these remarks in guarded tones. Greatly to their satisfaction they met no one while on the ​road. They had both wondered whether General von Berthold did not have a bodyguard camped somewhere near his headquarters, some of whom were likely to be moving about; though, to be sure, the hour was late for that sort of thing.
When they arrived at the scene of their previous escapade it was to find that one of the military chauffeurs had returned, and was even then taking a look at the engine of his car, for he struck several matches, and was thrusting his head down close to the machinery.
They halted to watch. A minute afterwards he tidied things up again, and Jack, hearing his loud yawn, decided he could not have discovered that some one had been meddling with his petrol supply.
Then the soldier vanished inside his big car, as though to find a comfortable seat, if his masters chose to linger an hour longer in celebrating with General von Berthold.
Tom led the way around, now approaching the building from an angle where they would be screened from the observation of the driver, did he chance to have his eyes open. They also took care to be ready to duck and lie low, in case the other chauffeur came from the back of the chateau.
But nothing happened to endanger them, and ​presently they were seeking a means of entering the castle. This proved the easiest thing possible, for there were no locks or bars attached to the door they tried. Once this barrier had been passed, they found themselves in a great hall, just such as Jack had always believed, from his reading, must be connected with every such old-time castle.
A light burned low. It was in itself a quaint lamp, and at another time the boys might have found themselves very much interested in it as a relic of times long since past.
Of course there could be no system of modern lighting in use at such an isolated habitation. Besides, electricity would have seemed sadly out of place in connection with so much that belonged to bygone days.
The tall lamp on the newel post at the foot of the broad stairway gave enough light to show one where to walk; and just then the two prowlers asked for nothing more.
Over to the right lay the wing that had not suffered from the work of the Hun despoiler. It was there the German general entertained his associates, discussing business until a late hour; and then giving themselves up to a little social enjoyment, which evidently became so pleasant that it was hard to break away.
The boys decided that since this wing was the ​only decent part of the building remaining, they were apt to find the object of their search in one of the many rooms it contained.
Having no guide to assist them, they must make a thorough search, neglecting no possible room where the little girl might be sleeping.
Of course their dodging about the corridors would be accompanied by more or less danger of discovery. There must be attendants moving about, for the Hun general would not inhabit this chateau unless he could have subordinates at his beck and call.
Once let any of these see strangers moving about with the air of spies—well, Jack imagined it would be nip and tuck with them as to whether they would be shot down like rats, get away by a close shave, or fall into the hands of the Huns, which last, he felt, would be the very worst fate that could befall them.
"It's upstairs for us, Jack." And with these words Tom led the way, headed for the upper floors of the chateau, even as a door opened and they heard a wild gust of uproarious chorus echo along the corridor leading to the dining hall in the right wing.
