The Boy Scouts for Uncle Sam Part 12

It was the following morning, a bright, clear day, with a clean swept sky overhead, and seaward, the waves whipping up into smart little whitecaps under a brisk breeze. Breakfast was over, the Boy Scouts'

bugle had sounded an a.s.sembly call, and now all were eagerly mustered about the submarine shed awaiting Mr. Barr's arrival and permission to go on board the _Peacemaker_.

True to his promise, the inventor had decided to make the boys partic.i.p.ants in the trial trip of the slate-colored diving boat.

Presently he appeared, accompanied by Ensign Hargreaves. Ten minutes later the chatting, laughing party was on board the _Peacemaker_, and half an hour after that she was p.r.o.nounced ready for the start. Mr. Barr took his place in the conning tower with Ensign Hargreaves beside him.

Barton was in the engine room, sullen and uncommunicative as usual. Rob and Merritt were on deck with one of the sailors, delegated to the duty of casting off the diving boat's lines.

At last came the word from the conning tower:

"Cast off."

Rob seized a rope and cast off from the stern bitts, while the sailor performed the same operation at the bow.

"Must we come inside now?" inquired Rob, through the open hatch of the conning tower.

"Not yet; unless you wish to. I will notify you before we dive," was Mr.

Barr's reply.

"Goodness, I hope he doesn't forget," said Rob laughingly, as the inventor turned on a switch and started the engines. The cigar-shaped form of the craft trembled as the powerful twin propellers beat the water. Then, handling as perfectly as a catboat, she backed slowly out of the shed and on to the open sea.

Once outside the shed, her helmsman headed the craft about and made directly east. To Rob and Merritt, standing on the deck, the sensation was a thrilling one. Faster and faster the craft was driven till great clouds of spray compelled the two lads to seek refuge in the conning tower.

Inside the boat the hum of machinery and the vibration of the powerful engines could be plainly distinguished. Rob glanced at the speed indicator on the steel wall of the "pilot house."

"Twenty-five knots! Phew! that's going some," he gasped.

"She can make thirty-two on the surface and twenty-one under water,"

said the inventor calmly.

As he spoke, he drew a lever toward him and the _Peacemaker_ appeared to leap forward like a horse under the lash.

Rob watched the handle of the indicator as it sped slowly around the dial. Up and up it crept till it stopped at thirty-two knots and a half.

"Jove! Barr," exclaimed the ensign, "this is the wonder craft of the century."

"I think I could get even more speed out of her, but I don't wish to strain the engines," was the confident reply.

"This is fast enough for me, thank you," said Rob to Merritt in an undertone.

From the conning tower lens the _Peacemaker_ appeared to be rus.h.i.+ng between two solid walls of water, so great was the quant.i.ty of spray she threw as she was remorselessly driven through the choppy sea. Yet the vibration was not nearly as bad as might have been expected.

"Let's go below and take a look at the engine room," said Merritt.

"All right; but I'll ask Mr. Barr's permission first," was Rob's rejoinder.

This was readily obtained, and the two boys went below. They found their comrades gathered in the large central cabin, excitedly discussing the novelty of their voyage. Pa.s.sing them, the young leader and his lieutenant made their way back into the machinery department. Barton glowered at them as they entered.

"Well, what d'ye want?" he asked gruffly.

"Merely to have a look at the engines," said Rob.

"Aw, what do you know about engines?" growled the man. "You ain't got no business in here."

"We have Mr. Barr's permission," rejoined Rob in a calm, even tone, determined not to let the fellow make him angry.

"Well, take a look around and get out quick," was the ungracious reply of the surly fellow.

Rob thought it best not to answer him, and arm in arm he and Merritt wandered among the flas.h.i.+ng, smoothly working machinery, which, despite its size and power, was almost noiseless. Whatever his failings might be in the way of politeness, Barton must have been a good engineer, the boys decided, for every bit of metal and paintwork about the engines was polished to a brilliant finish, and the engine room was as neat as a new pin.

Rob was examining the powerful pumps when his eye suddenly fell on a bit of paper lying on the floor. He picked it up, prompted by he knew not what instinct, and found that it was covered with minute sketches, apparently of machinery. The sketches were numbered and lettered, as if they had been "keyed" for the purpose of making the diagram clearer.

He was still examining the sketches when there was a swift step behind him and a heavy hand fell on his shoulder. Rob, facing about, looked into Barton's face. The engineer's countenance was livid, his eyes fairly blazed.

"Give me that paper, you young jackanapes!" he exclaimed, "and then get out of here--quick!"

"As to giving you the paper, here you are," said Rob, quietly handing the engineer the mechanical sketches. "If I'd known they were yours, I'd have returned them to you at once. I must ask you, however, to be a little less rough in your manners. I don't know what harm we've ever done you, that you should show such a dislike for us."

"Bah!" growled Barton as he turned away, thrusting the paper into a pocket of his jumper.

After this incident neither of the boys cared to remain in the engine room, and soon joined their companions in the main cabin.

They found them chatting and laughing over different boyish topics, and Merritt joined in the fun.

But Rob, usually talkative and bright, was strangely silent. He found himself musing over the incident of the sc.r.a.p of paper covered with mechanical sketches. Why had Barton become so agitated when the boy picked it up? What was there about the affair to excite the man so strangely?

Suddenly into the boy's mind there flashed a startling suspicion. But so grave was the idea that he dismissed it, or rather tried to; but with all his efforts the idea kept recurring like a dominant note in a piece of music. Rob decided to be on the watch and try to verify or disprove his suspicion, which was nothing more nor less than an idea that Barton was a traitor to his employer, and was also in the service of some powerful interests striving to get a grip on the secrets of the _Peacemaker_.

"That man will bear watching," decided Rob.

Scarcely had he come to this conclusion when Mr. Barr shouted down from the conning tower:

"I'm going to dive!"

The hearts of all the lads beat perceptibly quicker at the words.

They were about to descend into the unknown regions beneath the surface of the ocean, down into the dark waters where men's souls are put to a supreme test.

CHAPTER XIV.

FACING DEATH.

"Ready?" came the cry from the conning tower.

"All ready!" shouted back the lads a.s.sembled in the cabin, waiting for they knew not what.

"Then hold tight, we're going down quick."
