"The Sturmvogel!" answered Jimmie, pointing toward the harbor, where could be seen the speedy destroyer slipping quietly out to sea.
"Here"s hoping you have a good voyage, friend!" said Frank.
"Yes," added Jimmie, "we"ll see you a little later!"
"That reminds me," put in Ned, "we might as well get back to the "U-13"
and begin work. There"s no use delaying the game!"
"That"s right," agreed Harry. "These fellows are probably in a hurry for that submarine. We might as well be decent."
"Wait a minute," suggested Jimmie. "You"ve given me an idea! Your mention of the name of a certain undersea craft started a train of thought in my alleged brain. Take it easy for a moment!"
"Yes," cried Jack, in mock sympathy, "stand back! Give him air! If Jimmie is really going to think, let"s give him lots of room!"
"Aw, you go on!" scorned Jimmie. "I"ve got a right to think if I want to, haven"t I? I guess that"s my privilege!"
"Not unless you have a union card!" protested Jack, laughing.
"That"s all right," retorted Jimmie with a grin as he wrinkled a freckled nose at the other. "I was going to think about a scab, anyhow, so I don"t need a card. Besides, this is on overtime!"
"All right, you win!" declared Jack, submissively. "Go ahead!"
"If you"ll promise to never, never tell, I"ll let you in on the scheme!"
whispered Jimmie, glancing about to make sure that no strangers were within earshot. "Do you solemnly promise?"
"I do!" answered the boys in chorus, anxious to receive the news.
"Then here it is: If we could paint the name "U-13" on that tub there"s nothing to prevent our getting away in it!"
"Hush, Jimmie!" cautioned Ned, in a startled tone.
"Hush nothing!" declared the other boldly. "It"s now or never! The destroyer"s gone--everything"s gone that could chase us. Mackinder"s loose on this island. He"ll make us trouble if we stay. If we go now we are safe from pursuit until another German boat comes in unless they flash the news by wireless. In that case, we have an even chance of getting away. If we don"t go now tell me when we can get home?"
"I guess you"re right, Jimmie, but how are you going to work it?"
"Simply putter along this afternoon," explained the lad, "fixing the wiring and so on. If necessary, rip out some and replace it. We can get in one another"s way enough to kill a lot of time. After supper we"ll manage to slip back to the submarine, paint "U-13" on the side, every man to his post, let go lines easy and skedaddle for the open sea."
"It sounds easy enough," a.s.sented Harry.
"Yes, unless you happen to get caught!" agreed Ned.
"What is there to catch us?" asked Jimmie, bristling at this hint of opposition. "The guards are all wise to the fact that the channel is mined. They will be sleepy and lazy. They know that the torpedoes are not aboard yet and believe it impossible for the submarine to leave without a crew. The weather looks as if it were going to be rough. What more can you want? It looks to me as if we"d never have another chance like it!"
"Right you are, Mr. Wolf!" declared Frank. "I, for one, am willing to take a chance. I"ll go with you to the limit!"
"Here, too!" heartily agreed Ned. "How about it, boys?"
Eagerly the others signified their willingness to undertake the task suggested. They felt no compunction over the seizure of the boat.
"Now, we"ll have to do some tall thinking before night comes!" stated Jimmie. "Each of us"ll have his station and we must know just what to do at the proper time. I had this in mind ever since we came up the harbor past those boats. I noticed particularly the buoys marking the safe channel leading into this harbor."
"Good for you!" cried Ned, administering an affectionate slap upon Jimmie"s shoulder. "I knew you had something up your sleeve!"
"So did I!" added Jack. "I couldn"t guess what it was, though!"
"It was my arm!" declared Jimmie, with mock gravity. "Now, let"s go back to this "Unterva.s.serbootschiff" and stall around a while."
"Correct!" cried Harry. "We"ll rehea.r.s.e for this evening. We shall depend on Jimmie to be the pilot, though!"
"Leave it to me!" declared the younger lad. "I know where the buoys are!
I have them all located in my head!"
"But we must be mighty careful," declared Ned. "We don"t know how much English these fellows understand. They must not suspect!"
"Mum"s the word!" put in Frank. "Everybody mum!"
First visiting the warehouse at the wharf, where they procured a quant.i.ty of supplies, such as might be needed to carry out the work which they were supposed to be doing, the lads proceeded aboard the submarine.
Upon their arrival they found a painter at work inscribing the vessel with identifying marks. He had proceeded so far as to place "U-1--" on each side of the vessel. Jimmie joyfully declared that fortune was playing into their hands in this respect, and that if something would compel the man to quit work for a while the disguise could be quickly made.
At Ned"s request Harry began fitting wires from the storage batteries to the motors used for propelling the vessel. The boys were startled to hear him utter an exclamation of dismay. They found upon inquiry that he had endeavored to strip the insulation from a wire by using his pocket knife and had cut a finger badly.
"Pooh, pooh!" stated Jimmie, upon discovering the wound. "Don"t make so much fuss over a little thing like that. We"ll soon have you fixed up.
Here, just hold the wound closed with your other hand while I hunt up some bandages. You"ll be all right in a minute!"
But Harry declared that the wound pained excessively. He refused to treat the matter lightly, but gathered up the tools with which he had been working. These he deposited in a canvas bag in which they had been brought aboard the vessel.
Presently Jimmie located a first aid kit among the stores. He was not long in cleansing and bandaging the wound.
"There you are!" he stated. "Just as good as new! Now go lie down for a little while. I"ll finish this job if I know enough."
Chatting together in a somewhat nervous manner the boys anxiously awaited the approach of evening. As the time wore on their restlessness increased. Again and again they carefully went over each detail of their proposed plan for escape in the submarine.
It was decided that Jimmie should take the wheel while Harry stood watch at the engines. The others were a.s.signed to various other duties at favorable positions. Nothing remained except to wait for night.
A short time before darkness settled an orderly visited the craft. He was able to converse slightly in English.
"How are you getting along, boys?" he asked, as he stepped down the iron ladder. "Can we put the torpedoes aboard tomorrow?"
"Yes, I think you will be able to place the torpedoes after tomorrow morning," replied Ned. "We will have our work all done then."
"That is good!" was the other"s comment. "Where is Mackinder?" was his next question. "He will have to come ash.o.r.e now!" he added.
"Mackinder?" was Ned"s startled response. "He"s not here."
"But he was here!" firmly declared the orderly. "He was seen by one of the sentries to come aboard this vessel, and has not since been noticed going ash.o.r.e, although a close watch has been kept!"
"We haven"t seen him at all!" stated Ned, just as firmly.
