The Ocean Wireless Boys And The Naval Code

But, to his great relief, they reached the wharf, a tumble-down affair, before the tempest broke. The Curlew was made "snug," and this had hardly been done before a mighty gust of wind, followed by a blanket of rain, tore through the air.

"Just in time, boys," said Jack, as they set out on the run for the structure which they had observed from the water. On closer view it turned out to be nothing more than a barn, not in any too good repair, but still it offered a shelter.

The boys reached it just as a terrific blast of wind swept across the bay, roughening it with multitudinous whitecaps. A torrent of rain blotted out distances at the same time and turned all the world in their vicinity into a driving white cloud.

The barn proved to be even more rickety than its outside had indicated. The door was gone and its windows were broken out. But at least it was pleasanter under a roof than it would have been out in the open. The rain, driven by the furious wind, penetrated the rotten, sun-dried shingles and pattered on the earthen floor, but the boys found a dry place in one corner, where there was a pile of hay.

As the storm increased in fury the clouds began to blot out the daylight. It grew as dark as night almost. The roar of the rain was like the voice of a giant cataract.

"We may have to stay here all night," said Billy, after a long silence.

"That's true," rejoined Jack. "It would be foolhardy to take a boat like the Curlew out in such a storm."

Suddenly there came a terrific flash of lightning, followed by a sharp clap of thunder. It was succeeded by flash after flash, in blinding succession.

"My, this is certainly a snorter," exclaimed Billy, and the others agreed with him.

"We won't forget it in a hurry," said Jack. "I can't recall when I've heard the wind make such a noise."

To add to their alarm, as the fury of the wind increased, the old barn visibly quavered. It seemed to rock back and forth on its foundations. The noise of the wind grew so loud that conversation was presently impossible.

Suddenly there came a fiercer blast than any that had gone before. There was a ripping and rending sound.

"Great Scott! Boys, run for your lives, the old shack is tumbling down," cried Jack.

He had scarcely spoken when what he had anticipated happened. Beams, boards and shingles flew in every direction. There was no time even to think. Acting instinctively, each boy threw himself flat upon the pile of moldy hay.

Noddy, in his terror, burrowed deep into it. The noise that accompanied the dissolution of the old barn was terrific. Each boy felt as if at any moment a huge beam might fall on him and crush his life out. Above it all the wind howled with a note of triumph at its work of destruction.

The boys felt as if the end of the world had come.

CHAPTER XXI.

THE END OF JACK'S HOLIDAY

Fortunately, otherwise this story might have had a different ending, the barn was lifted almost entirely from its foundations and hurled over on its side. The roof was ripped off like an old hat and hurtled through the tempest to the water's edge.

None of the wreckage and débris struck the crouching boys. But the mere sound was terrifying enough. Even Jack was cowed by the tremendous force of the elements. Each lad felt as if the next moment would be his last.

But at last Jack mustered up courage and looked up. The beating rain, which had already soaked them all through, stung his face like hailstones.

"Hullo, fellows," he exclaimed, "is – is anybody hurt?"

"All right here," rejoined Billy. "But say, wasn't that the limit?"

"It sure was," agreed Jack. "At one time I thought we were goners, and – "

"Goo-oof-g-r-r-r-r-r!" An extraordinary sound, which can only be typographically rendered in this manner, suddenly interrupted him.

"Heavens, what's that?" gasped Billy, looking about him in a rather alarmed manner.

"Ugh-ugh-groof-f-f-f-f-f-f!"

"It's Noddy!" cried Jack.

"Gracious, he must be dying," gasped Billy.

In his eagerness to escape the full fury of the storm and the flying wreckage of the barn, Noddy had plunged into the hay with his mouth open, and now his throat was full of the dry stuff. He was almost choked.

"Pull him out," directed Jack, and he and Billy laid hold of Noddy's heels and dragged him out of the hay-pile. The lad was almost black in the face.

"Ug-gug-groo-o-o-o-o-o!" he mumbled, making frantic gestures with his arms.

"Goodness, this is as bad as the time he was almost drowned," cried Jack. "Clap him on the back good and hard. That's it."

There were several gulps and struggles, and then Noddy began to cough. But all danger from strangulation had passed, thanks to the heroic efforts of Jack and Billy.

"Phew! I thought I was choked," sputtered Noddy, as soon as he found his voice. "I'd hate to be a horse and have to eat that stuff."

"You are a kind of a horse," said Billy slyly.

"How do you make that out?" demanded Noddy, falling into the trap.

"A donkey," laughed Billy teasingly, but poor Noddy felt too badly after his experience in the hay to retaliate in kind.

After the restoration of Noddy, they began to survey the situation. All were soaked through, and the rain beat about them unmercifully. But they were thankful to have escaped with their lives. Through the white curtain of rain they could make out the outlines of the Curlew, riding at the dock.

"I'm glad to see that," observed Jack. "I was half afraid that she might have broken away."

"Then we would have been in a fine fix," said Billy.

"What will we do next?" asked Noddy, removing some fragments of hay from his ears.

"Wait till the clouds roll by," laughed Billy. "I guess that's about the program, isn't it, Jack?"

"Seems to be about all that there is to do," replied Jack; "but it seems to me that the storm is beginning to let up even now. Look in the northwest – it's beginning to get lighter."

"So it is," agreed Billy. "Let's get under that clump of trees yonder till it blows over altogether."

"Say, fellows, if we had a fire now, it would feel pretty good," observed Noddy.

"Well, what's the matter with having one?" asked Jack. "We can get some of those old shingles and tarred posts. They're pretty wet, but we can start the blaze going with dried hay from the bottom of the pile."

"Good for you. Volunteer firemen, get to work," cried Billy.

Soon the boys were carrying the dry hay and such wood as seemed suitable for their purpose to the clump of trees. Jack took some matches from his safe and struck a lucifer after the wood had been properly piled.

It blazed up cheerily. Each lad stripped to his underclothes and their drenched garments were hung in front of the hot fire. The dripping clothes sent up clouds of steam, but it was not long before they were dry enough to put on. By the time this was done the storm had abated. Presently the rain, which did not bother the boys under the thick clump of trees, ceased altogether. Only in the distance a dull muttering of thunder still went on. A rainbow appeared, delighting them with its brilliant colors.

"Well, that's over," observed Jack, as he dressed. "Now we'll go down and pump out the Curlew. I'll bet she's half full of water."

His conjecture proved correct. On their return to their trim little craft they found a foot or more of water in her hull. But this was soon disposed of and, with a brisk breeze favoring them, they set out once more for Pine Island. On their return they found Captain Toby, who had spied them from a distance, awaiting them on the dock.

In his hand he held a yellow envelope. It was a telegram for Jack. The boy eagerly tore it open, and for a moment, as he scanned its contents, his face fell. But almost instantly he brightened.

"Well, what's the news?" demanded his uncle.

"Good and bad," rejoined Jack. "I guess our holiday is over. Billy and I are ordered to join the Columbia as soon as we can."

"Hurrah! I was beginning to long for the sea again," declared Billy Raynor.

"I must confess I was, too," said Jack.

"It's a great life for lads – makes men out of them," said Captain Toby. "I must see if I've got two bottles of the Universal Remedy for you boys to take to sea with you," and he hurried off.

Noddy looked rather blue.

"You are lucky fellows – off for more adventures and fun," he said, "while I just stick around."

"Nonsense, you've got your business in New York to attend to, and, as for adventures, I've had plenty of them for a time, haven't you, Billy?"

"A jugful," declared Raynor. "Enough to last me for the rest of my life-time, and, anyhow, life at sea is mostly hard work."

"That's what makes it worth living," said Jack. "I'll be glad to get down to work again after our long holiday."

"And I really believe I will, too," said Billy; "and on a crack liner like the Columbia we may be able to make our marks."

"I hope we will. I mean to work mighty hard, anyhow," said the young wireless man, "but hark, there goes the bell for supper. Hurry up, fellows, I'll race you to the house."

The next day was devoted to saying good-by to the scenes and the people who had helped make up a happy vacation for the lads. Noddy, it was decided, would stay on with Captain Toby for the present, as his presence was not required in New York.

Of course the lads visited Captain Simms. He told them that his holiday also was almost over. The naval code was nearly completed, and he must get back to Washington within a week or so.

"Well, here's to our next meeting," he said, as he heartily clasped the hands of both lads in farewell.

Under what circumstances that meeting was to occur none of them just then guessed.

CHAPTER XXII.

"THE GEM OF THE OCEAN."

The Columbia, a magnificent and imposing vessel of more than 20,000 tons burden, lay at her New York dock two weeks later. Within her steel sides, besides the usual cabin accommodations, she had swimming pools, Roman courts, palm gardens and even a theater. Elevators conveyed her passengers from deck to deck. The new vessel of the Jukes shipping interests was the last word in shipbuilding, and from her stern flew the Stars and Stripes.

It was sailing day. From the three immense black funnels smoke was rolling. Steam issued, roaring from the escape pipes. The dock buzzed and fermented with a great crowd assembled to see their friends off on the first voyage of the great ship. Wagons, taxicabs and autos blocked the street in front of the docks. Photographers and reporters swarmed everywhere. The confusion was tremendous, yet, promptly at the hour set for sailing, the booming siren began to sound, last farewells were shouted, and the invariable late stayer on board made his wild leap for the gang-plank before it was drawn in.

A perceptible vibration ran through the monster ship. Her propellers began to churn the water white. A small fleet of tugs helped to swing her against the tide as she slowly backed into the stream. Majestically her monster bulk swung round, her bow pointing seaward. Her maiden voyage had begun.

It is doubtful if among her delighted passengers and proud officers, however, there were any more enthusiastic about the great vessel than two lads who were seated in the wireless operators' cabin on the topmost deck.

"Well, Billy, this is different from the old Ajax, eh?"

"Is it? Well, I should say so," responded Billy. "You ought to see the engine-room. You could have put the Ajax in it, almost."

"We ought to be proud of our jobs," continued Jack.

"I know I am. It's a great thing to be part of the human machinery of a huge vessel like this, and the best part of it is that she flies the American flag," added Billy enthusiastically.

"I heard that the Gigantia, of the London Line, sails to-day, too. By Jove, there she comes now."

He pointed out of the open door back up the river. The great British steamer, till then the biggest thing on the ocean, was backing out. Her four red-and-black funnels loomed up imposingly above her black hull.

"Then we'll have a race for certain," said Billy, his eyes dilating with excitement; "good for us, but my money goes on the Columbia."

"That Britisher can travel, though," said Jack.

"Oh, we won't have an easy time of it, but I'll bet my shirt we'll win the blue ribbon of the ocean."

"I hope so," rejoined Jack with a smile at the other's enthusiasm. "But what do you think of my quarters, Billy?"

"Why, they're fit for a king or a millionaire," laughed Raynor. "I'll bet you never thought, when you were in that little rabbit hutch of a wireless room on the old Ajax, that some day you'd be traveling in such style?"

Raynor's eyes wandered to the instrument table, with its array of the most up-to-date wireless apparatus.

"Hullo! What's that thing?" he asked suddenly, pointing to a device that looked unfamiliar. It was a box-shaped arrangement, metal, with complicated wires strung to it and had a "telephone" receiver attached to it with a band to hold it securely to the operator's head.

"Oh, that's an invention of my own that I'm trying out," said Jack. "I don't just know what success I'll have with it. I haven't really put it to the test yet."

"What do you call it?"

"The Universal Detector," replied Jack.

"Just what is that?"

"Well, at present you know a ship can only receive wireless messages from a ship that is 'in tune' with her own radio apparatus. The Universal Detector should make it possible to catch every wireless sound. I am very anxious, if I perfect it, to get it adopted in the navy. It would be of great value in time of war, for by its use every message sent by an enemy, even if they were purposely put 'out of tune,' could be caught."

"By the way, speaking of the navy, did you hear from Captain Simms?"

"Yes; he is still up at Musky Bay. Some difficulties in the code have arisen, and he will not be through with his work for two weeks or more yet, he says."

"No more attempts to steal his work, or to spy on him?"

"He doesn't mention any. I guess we're through with the Judson crowd."

"Looks that way. What a gang of thorough-paced rascals they were."

"I guess Judson's business must be in a bad way to make him take such desperate chances to recoup by landing that contract."

"I suppose that's it."

Raynor lifted his eyes to the ship's clock above Jack's operating instruments.

"By Jove, almost eight bells! I've got to go on watch. This is my first job as second engineer, and I mean to keep things on the jump. Well, so long, old fellow."

"See you this evening," said Jack, as Raynor hurried off.

Jack soon became very busy. The air was full of all sorts of messages. Besides that, his cabin was crowded with men and women who wished to file last messages to those they left behind them. He worked steadily through the afternoon, catching meteorological radios as well as information from other steamers scattered along the Atlantic lane.

He knew that he might expect hard work and plenty of it all that day. There would be no chance for him to experiment with his Universal Detector. About dusk, Harvey Thurman, his assistant, came into the wireless room to relieve him while he went to dinner.

Thurman was a short, thick-set young man, with a flabby, pallid face and shifty eyes. He had got his job on the new liner through a "pull" that he possessed through a distant relationship with Mr. Jukes. Jack had not met him before, and, since they had been on board, they had exchanged only a few words, but he instinctively felt that he and Thurman were not going to make very good shipmates.

As Jack relinquished the head-receivers and the key to his "relief," Thurman's gaze rested on the Universal Detector.

"What's that?" he demanded.

"Oh, just a little idea I'm working on," said Jack, "a new invention. If I can perfect it, it may be valuable."

"Yes, but what is it? What's it for?" persisted Thurman.

Jack explained what he hoped to accomplish with the instrument, and an instant later was sorry he had done so, for he noticed an expression of cupidity creep into Thurman's eyes. The youth persisted in asking a host of questions, and Jack, having started to explain, could not very well refuse to answer. Besides, inventors are notoriously garrulous about their brain children, and Jack, even though he did not like Thurman, soon found himself talking away at a great rate.

"Huh, I don't think the idea's worth a cent," sniffed Thurman contemptuously, when Jack had finished.

"I guess that's where you and I differ," said Jack, controlling his temper with some difficulty, for the sneer in Thurman's voice had been marked. "I'm going to make it a success, and then we shall see."

He left the wireless room, and the instant he was gone Thurman, with a crafty look on his flabby face, eagerly began examining the detector. As he was doing so Jack, who had forgotten his cap, suddenly reëntered the wireless room. Thurman had been so intent on his scrutiny of the detector that he did not hear him.

"You appear to be taking great interest in that useless invention," said Jack in a quiet voice.

Thurman started and spun round. His face turned red and he had an almost guilty look.

"I didn't think you were coming creeping back like that," he exclaimed, "a fellow would almost think you were spying on him."

"Have you any reason to fear being spied upon?" asked Jack.

"Me? No, not the least. That's a funny question."

"I want to tell you, Thurman, that my invention is not yet completed and therefore, of course, is not patented. I was pretty free with you in describing it, and I shall trust to your honor not to talk about it to anyone."

"Certainly not," blustered Thurman. "I'm not that sort of a chap."

But, after Jack had gone out, he resumed his study of the detector a second time, desisting every time he heard a step outside.

"So it's not patented, eh?" he muttered to himself. "That will help. It's an idea there that ought to be worth a pot of money."

CHAPTER XXIII.

JACK'S BIG SECRET

The next day Jack found an opportunity to sandwich in some work on his invention between his regular work. The thing fascinated him, and he tried and tested it in a hundred different combinations. Suddenly, just after he had altered two important units of the device, a new note came to his ears through the "watch-case" receivers that were clamped to his head.

"It's code – somebody sending code!" exclaimed Jack, and then the next instant, "it's some ship of the navy! Hurrah! The detector is working, for they use different wave lengths from the commercial workers, and, if it hadn't been for the Universal Detector, I'd never have been able to listen in at their little talk-fest."

He waited till the code message, a long one from Washington to the Idaho, of the North Atlantic fleet at Guantanamo, Cuba, was finished, and then he could not refrain from "butting in."

"Hello, navy," he chattered with the wireless key, "that was a nice little message you had. How's the weather up your way?"

"Who is this?" demanded the navy wireless in imperious tones.

"Oh, just a fellow who was listening," responded Jack.

"Butting in, you mean. But say, how did you ever get on to our sending? We were using eccentric wave-lengths to keep our talk a secret."

"I'll have to keep how I caught your talk a secret, too, for the present, old man."

"Great Scott! It isn't possible that you've solved the problem of a universal detector. Why, that's a thing the navy sharps have been working on for years."

"I can't say how I caught your message," shot back Jack's radio through space.

"You'll have to tell if the government gets after you," was the reply. "Uncle Sam isn't going to have a fellow running round loose with anything like that."

"What do you mean?"

"That you will be forbidden to use it."

"Is that so?"

"Yes, that's so. I'm going to make out a report for my superiors about it right now. You're pretty fresh."

"Put that in the report, too," chuckled the Columbia's wireless disdainfully.

"You'll find it's no joke to monkey with the government," snapped back the naval man.

Jack didn't answer. A message from the Taurus, of the Bull Line, was coming in. She had sighted an iceberg, something very unusual at that time of year. Jack hurried the message, which gave latitude and longitude of the menace, to Captain Turner.

"Well, that won't bother us," said that dignitary. "We're far to the south of that. Those Bull fellows run to Quebec. Send a radio to Captain Spencer, of the Taurus, thanking him for his information."

The great man, the captain of a liner, who has literally more power than a king, lit a cigar, and bent his head once more over the problem in navigation he was wrestling with. Jack saluted and hurried back to his quarters.

He was highly elated over the success of his Universal Detector. The threats of the government man did not alarm him, for he did not propose to place his invention on the general market, but to sell it outright to the government, whose secret it would then remain.

He resolved to test it again. A moment after he had put the receivers to his ears, a broad grin came over his face. The air was literally vibrant with the calls of the navy men, flinging their high-powered currents through space.

"… he's a cheeky beggar, whoever he is, but he's got the goods," was the first he heard.

"Hum, that's Mr. Washington," thought Jack. Then, from some other point came another message.

"Great Scott! Uncle Sam won't let him get away with anything like that."

"I should say not. The Secret Service department is already at work trying to find out who the dickens he is."

"That will be a sweet job," came the naval station at Point Judith.

"Talk about a needle in a haystack," sputtered the U. S. S. Alabama.

"Not a patch on it," agreed the great dreadnought Florida.

Then came Washington again.

"I'll tell you it's stirred up a fuss here," he said. "I wonder who it can be."

"Maybe that Italian fellow who invented the sliding sounder," suggested the Florida.

"Or Pederson, out in Chicago," came from a land station. All the navy men appeared to be joining in the confab.

"Gracious, what a fuss I've stirred up," thought Jack, with a quiet smile. "They'd never guess in a million years that it's a kid of an operator who's causing all the trouble."

"No; both the men you mentioned are in Europe," declared Washington. "The department's been trailing them since they got my news."

"Well, the wireless men are going to be a happy hunting ground for the Secret Service fellows for this one little while," chuckled the Florida.

"Wonder if he's listening now?" struck in the North Dakota, which had not yet talked.

"Shouldn't wonder," remarked the Idaho.

Jack pressed down his key and the spark began to flash and crackle.

"You fellows are having a grand old pow-wow," he said. "Sorry I can't give you any information. I know you're dying of curiosity."

"You've got your nerve, I must say," sputtered Washington indignantly. "Have you been listening right along?"

"Yes; that Secret Service hunt is going to be very interesting."

"It won't be very interesting for you, whoever you are, when they get you," thundered the mighty Florida. "It's bad business monkeying with Uncle Sam."

"Maybe they won't get me," suggested Jack's spark.

"Oh, yes, they will," came from Washington, "and you'll find it doesn't pay to be as sassy as you've been."

"M-M-M," sent out Jack mischievously.

The three letters mean, in telegraphers' and wireless men's language, "laughter."

Washington's dignity took fire at this gross insult. They must have sizzled as from the national capital an angry message shot out to the other ships to talk in code. Jack's fun was over, but he had thoroughly enjoyed all the excitement he had stirred up. As he laid down the receivers Raynor came in.

"You look tickled to death over something," he exclaimed. "What's up?"
