"Why?"
"So that the speed of the submarine boat shall always be ahead of the speed of any battleship afloat."
"Again, why?"
"Why, so that the submarine can give effective chase to a battleship."
"But submarines are intended only to go with fleets of their own country, or else to remain on station at or near the mouths of harbors to be defended."
"All well and good," argued Captain Jack, nodding. "In future wars a battleship fleet is likely to keep away from any harbor known to be defended by the enemy"s submarine boats. But, if a submarine torpedo boat could have speed enough to give chase to a fleeing battleship, and sink when within range of the battleship"s guns, yet still be able to pursue, under water, and destroy the battleship, that would mean the day when battleships wouldn"t be of any further use, wouldn"t it?"
"Undoubtedly," admitted Mr. Farnum. "But you see, captain, so far as present human ingenuity goes, a boat can"t be built to sail as fast under water as another can be made to go on the surface."
"But that"s the problem I"m going to tackle, as soon as I get our plans a little further along," murmured David Pollard, eagerly. "Benson is right. When we get a submarine boat that can pursue the fastest battleship, on the surface or below it, then the United States, with a hundred such submarines, could defy the combined naval powers of the world. If the United States can own a large fleet of such boats, then we can control the seas of the world."
No more attempts at diving were made on the trip. The horror of that last dive remained with all, safe as they now were.
All the way the "Pollard," though well out from sh.o.r.e, ran within sight of the light-houses.
Shortly before two o"clock in the morning Captain Jack Benson, again at the deck wheel, steered in for the light at Cape Adamson. He was going at slow speed as he rounded the point and headed in for the bay.
"Be careful how you go, captain, and be on the alert to obey signals,"
cautioned Mr. Farnum. "We"ve got to thread our way into a perfect hornet"s nest of war craft. A dozen battle ships, several cruisers and a flotilla of torpedo boats are at anchor over yonder."
It wasn"t long before the searchlight of one of the battleships picked up the "Pollard" with its broad ray. Then, from the flagship the colored lights that blazed out and faded spelled the signal:
"Who are you?"
"Pollard, submarine," replied the little craft"s signal lights.
"Expected. Come in close for orders," came the signaled answer.
There was something sombre, grim, awesome about this great fleet of mighty fighting craft as the young captain stole his boat in among them.
These craft represented much of Uncle Sam"s fighting strength, a bulwark of safety, to our coasts and commerce.
Close up within megaphone-hailing distance Captain Jack ran his boat.
The watch officer of the "Columbia," the battleship that served as flagship to the fleet, stood with megaphone ready.
"Ahoy, "Pollard"!" he called.
"Ahoy, flagship!" Captain Jack answered through a megaphone.
"Fleet patrol boat will show you to your anchorage. Are your owners aboard?"
"Yes, sir."
"Then, in the morning, they will hear from the admiral."
"One moment, sir," Captain Jack shouted back. "We have aboard a maniac, a man who tried to destroy us on the trip down. He has naval discharge papers."
"His name?"
"William Henderson."
"Henderson? Wait a moment!" came back from the flagship"s rail.
Those on the "Pollard"s" deck saw a younger officer leave the watch officer and hurry away. This younger officer soon returned with a paper which he handed to the watch officer.
""Pollard" ahoy!" came from the latter.
"Flagship ahoy!"
"William Henderson was an inmate of a naval hospital, where he had been sent to be watched on a suspicion of lunacy. A few days ago he escaped. We"ll take him off your hands and see he is sent back where he belongs."
"Thank you, flagship."
The fleet patrol boat, which had been hovering near, a small cabin launch, now steamed in alongside the submarine. An ensign and four men came aboard. Captain Jack led them below, pointing out Henderson.
The four sailors lifted him, carrying him up and over the side to their own boat.
"Now, follow us, captain," directed the ensign, "and we"ll lead you to your anchorage."
Five minutes later the "Pollard" rode snugly at anchor, with all made trim and secure. But Captain Jack and his two boy friends, despite the lateness of the hour, were in no hurry to turn in below.
It was the first glimpse any of the trio had ever had of such an imposing war fleet, and all wanted to stay on deck drinking in the glory of the sight.
CHAPTER XX
"ONE ON" THE WATCH OFFICER
At nine o"clock the next morning Messrs. Farnum and Pollard were sent for to report aboard the flagship, where they had a long talk with Admiral Bentley.
The result was somewhat disappointing. During the manoeuvres a board of naval officers would be sent aboard the "Pollard" to observe what she could do in surface running, diving, etc. The "Pollard," however, was not to be included in any of the deep-sea manoeuvres of attack and defense, as there were already two Government submarines with the fleet, and the work of these had been mapped out.
"However, that"s the best we can do, and we must be satisfied," sighed Jacob Farnum to Captain Jack. "We"ll find plenty of chance to show what we can do, and I know the Navy officers will see that we get a fair show at Washington."
"Of course," nodded Captain Benson, loyally. "When they see just what a handy craft the "Pollard" is at all times, they"ll be wild to have a few "Pollards" in the Navy."
"That"s the way to talk," beamed the anxious inventor, all of whose hopes of the future were based on the developments of these few days.
"It"s the way to talk, sir," replied Captain Jack, "because it"s the truth. We"ll show these Navy folks so much about the "Pollard" that, being men of good sense, they"ll see the point."
In the afternoon several delegations of naval officers visited the little submarine from the different craft in the fleet. The tiny cabin was crowded with visitors, the air being thick with cigar smoke much of the time. What astounded many of the visitors was the extreme youthfulness of captain and crew, but Jacob Farnum a.s.sured the naval callers that these young men had accomplished all that had been done with the "Pollard" up to date.
"And I"m going to be wholly satisfied, gentlemen," added the builder, "with the impression that will be made upon you by what my crew of boys can show you."
