"That's true, too, as I can easily testify," added Dave.

Their visitor proved to be none other than von Liebknecht, the officer in charge of the regiment, with whom they were now well acquainted.

"You boys are wanted at the rear," he announced. "Walk directly along the train and report at the coach reserved for the Kaiser."

"Yes, sir," answered Jimmie, giving the Boy Scout salute. "And who shall we find there to whom we shall report?"

"Fritz and Otto, whom you both know, will be on duty. Tell them that I have sent you back and that you are there for special duty. They are expecting you and will give you instructions."

"Very good, sir," replied Jimmie gravely. Then, as von Liebknecht turned to proceed toward the little station building, he added:

"I see an accident has happened to the aeroplane. I hope the aviator was not badly injured. They're carrying him away."

For a moment von Liebknecht paused to look searchingly into the face of the boy. Jimmie returned his gaze unflinchingly. He said afterward that it was quite the hardest thing he had ever attempted, and several times he was on the point of letting his gaze wander. However, he stood the ordeal well and presently heard the other say:

"He is not badly injured. A few minor contusions and a scratch or so comprise all his hurts. It is very fortunate, however, for all parties concerned," placing peculiar emphasis upon the phrase, "that it is no more serious. It might mean trouble for some one."

"I sure am glad that the fellow is able to get about," was Jimmie's statement. "He's a plucky chap, and from what I saw of him when he landed he is an expert in the matter of handling the aeroplane. It would certainly be a pity if he should be killed or badly injured."

"The German army would lose one of its very best aviators if he were gone," von Liebknecht replied, "and although the loss of his life would be irreparable, it might be decided to take payment in kind."

"Meaning?" asked Jimmie, paling slightly under the freckles as the full import of the other's words came to him.

"Meaning," von Liebknecht replied with wonderful self-control, "that you will report at once as I directed you."

With these words he turned and resumed his interrupted journey toward the station, striding along with considerable haste.

"Gee, Bo!" exclaimed Jimmie as the two lads started for the rear, "that was some close shave! That fellow has got a suspicioner tucked away inside his brain that is working overtime. Every little thing that happens he thinks is caused by a spy or something like that. I wouldn't have his disposition for a million dollars in Mexican money."

In spite of the gravity of their position Dave could not resist the temptation to laugh at Jimmie's exaggerated statement.

The lads could see that the switching engine that had been moving the coach was making preparations to couple it to the rear of the train, and lost no time in proceeding in its direction.

As stated by von Liebknecht, they found Otto and Fritz acting as guard.

The two had received the instructions and were prepared to take charge of the two lads accordingly.

Shortly after Jimmie and Dave reached the coach it was attached to the train and the journey westward was resumed.

Jimmie and Dave had been placed in a compartment at the rear of the coach, together with several of the attaches of the Kaiser's staff.

The Kaiser himself occupied a compartment near the forward end, and here he was conducting the necessary details of preparation for the exceedingly strenuous work that lay before the German forces.

For a long time the train jolted on. Engines were changed and train crews replaced by others, and still the regiment proceeded westward.

The soldiers disposed themselves about the cars in such positions as were possible and slept the tired sleep of overworked humanity.

Still the Kaiser and his staff sat and discussed plans and prepared orders for the grave matters confronting them in the western amphitheatre of war. Apparently their endurance knew no bounds. Sleep seemed to be farthest from their thoughts.

But at length, wearied from their long vigil and arduous labors, the group were glad to find the Kaiser disposed to s.n.a.t.c.h a few moments of rest. The maps were folded, the dispatch boxes closed, and all prepared to find positions where they could sleep.

"But the two boys!" von Liebknecht suggested as final preparations were being made for dismissing the group. "What of them?"

"Their case can be settled at once," declared the Kaiser. "Let them be brought here and we shall question them."

And so it was that as the dawn was breaking ruddily in the east Jimmie and Dave were wakened from their sound sleep and informed that their presence was desired in the compartment where the Kaiser waited.

On their feet almost instantly, the two lads rubbed the sleep from their eyes. They stretched and yawned prodigiously.

"Setting-up exercise," commanded Jimmie sharply. "It'll wake us up in fine shape. Here goes--one, two three."

Dave followed Jimmie's example, and the two went through a short routine of bending and turning exercises that started the blood coursing through their veins and cleared away the fog of sleep.

"There!" announced the red-headed lad presently to the officer. "Now we're ready for the Kaiser or the whole bloomin' German army. Lead on and we'll follow as closely as you like."

Their movements had been closely observed by a group about them, and, in spite of the fact that they were foreigners, many a kindly glance told of the att.i.tude of the men with whom they were placed.

The train had slowed somewhat in climbing a grade, and the boys found no difficulty in following their guide. As they proceeded slowly toward the forward end of the coach Dave found a chance to nudge Jimmie.

"If we only knew what was about here, this would be a grand chance, don't you know, to give them the slip."

"What do you mean, give them the slip?"

"Why, drop off the train and fade away into the landscape somewhere hereabouts!" declared Dave with a glance over his shoulder.

"With the day just opening, like switching on all the electric lights in the world!" objected Jimmie. "The intention of the gentleman from Vancouver is excellent, but I'm afraid that his execution of the maneuver would be decidedly rotten. It won't do just now."

"Perhaps not," sighed Dave, "but just the same, I'd like to try it out once to see whether we could make a go of it."

"Nothing doing!" declared Jimmie. "We're under suspicion already, or I miss my guess. The events of the last few hours are enough to let us know that if we tried anything like that the Germans wouldn't take kindly to any such plan. We wouldn't get very far, I fear."

"All right, then," agreed Dave. "I guess you're right."

"Sure I am!" went on Jimmie rea.s.suringly. "Just leave it to me, old chap, and we'll grab the first opportunity that comes along with a genuine Frank Gotch toe hold and hang on till we put the German shoulders to the mat for the count. Leave it to me."

"I'll be with you for all I'm worth!" declared Dave.

Their conversation had attracted the attention of the officer, who now commanded silence on their part.

"We are now approaching the Kaiser's apartment," that worthy stated, with a show of reverence as he p.r.o.nounced the t.i.tle of his superior.

"You shall not talk until you are asked to do so."

"Correct!" came Jimmie's reply. "We will keep as still as mice."

The three were admitted in response to the officer's knock, and the boys found that the little compartment was now somewhat crowded. Their presence filled the place until there was not a vacant seat.

For some moments as the train rolled along the upgrade the Kaiser paid no attention to them, busying himself over a bundle of papers.

At length he looked up and searched the boys carefully with his piercing gaze. After he had apparently taken a complete inventory of the two boys--one in the uniform of his own Uhlans and the other in the uniform of the Boy Scouts--he turned to one of his aides.

"What is the charge you wish to bring against these young men?"
