"I wonder how the rascal became acquainted with Judson?" pondered Billy.
"Mixed up with him in some crooked deal or other before this," said Noddy.
"I shouldn't wonder," said Jack.
They began to walk back to the hotel. They did not enter the lobby by the main entrance, for the path they followed had brought them to a side door. They were glad of this, for, screened by some palms, they saw, bending intently over the register, the forms of the three individuals whose conversation they had overheard.
CHAPTER VII.
THE NAVAL CODE
"Now that you boys know the nature of the work I have been engaged on, I may as well tell you that confidential reports from Washington have warned me to be on my guard," said Captain Simms. "It was in reply to one of these that I sent a code dispatch to-night."
It was half an hour later, and they were all seated in the Captain's room, having told their story.
"But I should have imagined making up a code was a very simple matter," said Billy.
"That is just where you are wrong, my boy," smiled Captain Simms. "A commercial code, perhaps, can be jumbled together in any sort of fashion, but a practical naval code is a different matter. Besides dealing in technicalities it must be absolutely invulnerable to even the cleverest reader of puzzles. The new code was necessitated by the fact that secret agents discovered that an expert in the employ of a foreign power had succeeded in solving a part of our old one. It was only a very small part, but in case of trouble with that country it might have meant defeat if the enemy knew even a fragment of the wireless code that was being flashed through the air."
"Have you nearly completed your work?" asked Jack.
"Almost," was the reply, "but the fact that these men are here rather complicates matters. At Musky Bay, the name of the little settlement where I am stopping, they think I am just a city man up for the fishing. I do not use my right name there. By an inadvertence, I suppose it was habit, I wrote it on the hotel register to-night. That was a sad blunder, for it is practically certain that these men will not rest till they have found out where I am working."
"At any rate I'm mighty glad we followed that Jarrow," said Jack.
"And caught enough of their plans to put you on guard," chimed in Billy.
"Yes, and I am deeply grateful to you boys," was the rejoinder. "'Forewarned is forearmed.' If Judson and his crowd attempt any foul tactics they will find me ready for them."
"Judson apparently wishes now that he had not been so anxious to secure that contract as to promise the naval code as a sort of bonus," said Jack.
"I don't doubt it," answered Captain Simms. "Now that I recall it, I heard rumors that Judson, who once had a steel contract with our government, is not so sound financially as he seems. I judge he would go to great lengths to assure a large contract that would get him out of his difficulties."
"I should imagine so," replied Jack. "What was the reason he never did any more work for the government?"
"The inferior quality of his product, I heard. There were ugly rumors concerning graft at the time. Some of the newspapers even went so far as to urge his prosecution."
"Then we are dealing with bad men?" commented Jack.
"Unquestionably so. But I think we had better break up this council of war and get to bed. I want to get an early start in the morning."
But when morning came, it was found that the repairs to the Skipjack would take longer than had been anticipated. While Captain Simms remained at the boat yard to superintend the work, the lads returned to the hotel and addressed some post cards. This done they sauntered out on the porch. Almost the first person they encountered chanced to be Jarrow. He started and turned a sickly yellow at the sight of them, although he knew, from an inspection of the register the night before, that they were there.
"Why – er – ahem, so it is you once more. Where did you spring from?"
"We came out of that door," murmured Jack, while Noddy snickered. "Where did you come from?"
"I might say from the same place," was the rejoinder, with a look of malice at Noddy.
"We thought you were in the west," said Billy. "Great place, the west. They say the climate out there is healthier than the east – for some folks."
"Boy, you are impudent," snarled Jarrow.
"Not at all. I was merely making a meteorological remark," smiled Billy.
"Wait till I get that word," implored Noddy, pulling out a notebook and a stub of pencil.
"Splendid grounds they have here for taking strolls at night," Jack could not help observing.
From yellow Jarrow's face turned ashen pale. Muttering something about a telephone call, he hurried into the hotel.
"Goodness, that shot brought down a bird, with a vengeance," chuckled Billy.
Jarrow's head was suddenly thrust out of an open window. He glared at the boys balefully. His face was black as a thundercloud.
"You boys have been playing the sneak on me," he cried angrily. "If you take my advice, you will not do so in the future."
He withdrew his head as quickly as a turtle draws its headpiece into its shell.
"He's a corker," cried Noddy. "I'll bet if he had a chance, he'd like to half kill us."
"Shouldn't wonder," laughed Jack, "but he isn't going to get that chance. But hullo! What's all this coming up the driveway?"
The others looked in the same direction and beheld a curious spectacle.
CHAPTER VIII.
A MONKEY INTERLUDE
"Well, here's something new, and no mistake," cried Billy.
"Good, it will help pass our morning," declared Noddy, who was beginning to find time hang heavily on his hands now that he had nobody to play pranks on, like those he used to torment poor Pompey with.
An Italian was coming up the road toward the hotel. Strapped across his shoulders was a small hand-organ. He led a trained bear, and two monkeys squatted on the big creature's back. He came to a halt near the grinning boys.
"Hurray! This is going to be as good as a circus!" declared Noddy. "Start up your performance, professor."
"They're off!" cried Billy.
Summer residents of the hotel, anxious for any diversion out of the ordinary, came flocking to the scene as the strains of the barrel organ reached their ears, and the bear, in a clumsy fashion, began to dance to the music of the ear-piercing instrument.
"Where are you going, Noddy?" asked Jack, as the red-headed lad tried to get quietly out of the crowd.
"I just saw a chance for a little fun," rejoined Noddy innocently.
"Well, be careful," warned Jack. "This is no place for such jokes as you used to play on Pompey."
"Oh, nothing like that," Noddy assured him as he hurried off.
"Just the same I'm afraid of Noddy when he starts getting humorous," thought Jack.
He would have been still more afraid if he could have seen Noddy make his way to the hotel kitchen and bribe a kitchen maid to get him three large sugar cakes. Then he made his way to the dining-room, and boring tiny holes in the buns filled each of them with red pepper from the casters.
"Now for some fun," he chuckled.
"I just know that boy is up to some mischief by the look on his face," remarked an old lady as he hurried by.
Quite a big crowd was round the Italian when Noddy got back. Almost as soon as he arrived the man began passing the hat, and taking advantage of this, Noddy proffered his buns to the animals. They accepted them greedily.
"Peep!
