"Certainly, sir," nodded Jack. And then he continued as if reciting a lesson: "Just give that firing lever at the back of the after port a quick shove to the right and downward. That releases the charge of compressed air and forces the torpedo out. At the same instant the forward port opens, so that the torpedo can be shot out into the water.
The compressed air also serves to keep the sea water from rushing in through the torpedo tube. When the lever is swung up and back again that closes the forward port, and it is then safe to open this after port."
"You"ve committed that to memory," laughed the naval lieutenant.
"Oh, we"ve often talked this over, all three of us," smiled Jack.
"Then, since you understand this part so well, Benson," proposed Mr.
Danvers, "perhaps you"d like to go forward, on deck, and see when this dummy torpedo is fired?"
"I surely would," agreed the submarine boy "And Eph can just as well come with me."
The two submarine boys, therefore, hastened above, out on the platform deck, and then further forward on the upper hull, until they lay out along the nose of the "Hastings."
Danvers reached Ewald"s side in the tower, while Biffens waited below, at the lever, for the firing signal.
The "Hastings" was now drifting, rather aimlessly, something more than four hundred yards away from the scow. As the sea was roughening all the while, the two submarine boys out forward were having a hard time of it. Added to that, icy spray was falling over them.
Lieutenant Danvers quickly rang for speed and then brought the submarine boat within about three hundred yards of the scow, and at a position that pointed the nose of the "Hastings" at the middle of the scow"s hull, the line of fire making a right angle with the scow.
"Get ready to watch, out there!" warned the naval officer.
"Now, Eph," glowed Jack, "we"re going to see the thing we"ve so often dreamed about! We"ll see that dummy torpedo leap forth, like a real one. For a little way, at least, we ought to see the track of the torpedo."
"Feel like betting the dummy will bit the scow?" questioned young Somers, half doubtfully.
"Of course it will," retorted Jack Benson, scornfully, "with naval experts on the job!"
Lieutenant Danvers gave the firing signal.
In the silence that followed, the two submarine boys hanging over the nose of the boat heard just a m.u.f.fled click below. Then--
"There it goes!" shouted Jack Benson, with all the glee in the world.
Down beneath them, under the nose of the "Hastings" an object shot into brief view. First the war-head, then the middle, then the tail and propeller of a fourteen-foot Whitehead torpedo swept away from them, two or three feet below the surface of the waves. A line of bubbles came to the surface, showing that the torpedo was headed, straight and clean, for the stone-laden scow over on the ocean. Then the torpedo, still under water, pa.s.sed out of their range of view.
"Hurrah!" yelled Jack Benson, leaping to his feet with all the glee and fervor of the enthusiast. "Hurrah!"
"Hurrah!" bellowed Eph Somers, for the glory of the game had gotten into his blood, too. Both submarine boys capered up and down on the platform deck.
But Lieutenant Danvers sat with left hand on the conning tower steering wheel, his watch in his right hand. He was counting the seconds.
"Look out for the signal," called the naval officer, coolly. "When I tell you, then look out for what happens over at the scow. Er--now!"
They were too far away to hear the impact, but the two submarine boys saw a slight commotion in the waters under the scow"s rail. Then the dummy torpedo bounded back, rising and floating on the surface--spent!
Had that torpedo contained the fighting service charge of two hundred pounds of gun-cotton it would have shattered and sunk the biggest, staunchest, proudest battleship afloat.
"It"s uncanny--isn"t it?" gasped Jack Benson, feeling an odd shudder run over him.
CHAPTER III
STRUCK BY A SUBMERGED FOE
"Yep!" agreed Eph Somers, blaster of day-dreams. "But say?"
"Well?" demanded Captain Jack.
"At the same time," muttered Eph, grimly, "I"m glad that scow isn"t a real battleship, with a half a dozen twelve-inch cannon turned on us."
"Humph!" muttered Jack, dryly, "if that scow were an enemy"s battleship, twelve-inch barkers and all, we"d be twenty feet under the surface, and we"d be out of sight and out of mind."
"Quite right," nodded Lieutenant Danvers. "In a contest of that sort I"d feel fifty times safer here than on the battleship we were after.
Now, Benson, you"ve seen the first part of it. We have the other dummy to fire. The real gunner, on a submarine, is the fellow at the wheel. Do you want to take the wheel, manoeuvre the boat and give the order for the next dummy shot?"
"Do I?" uttered Jack Benson. "Just!"
Orders were then given to place the other dummy torpedo in the tube, and this done, Jack took his place at the wheel, while Eph Somers and the lieutenant stood outside. At the naval officer"s direction Jack Benson came up on the other side of the scow, about three hundred yards away, with the nose of the "Hastings" so pointed that the torpedo dummy could be delivered straight amidships.
At just the right moment Captain Jack pa.s.sed the order to fire. Then he watched the scow with a strange fascination. Danvers stood, watch in hand.
"Now!" he shouted.
Barely two seconds later the second dummy torpedo rose, a few yards back from the side of the scow.
"That torpedo struck, full and fair," nodded Lieutenant Danvers, turning toward the conning tower. "Mr. Benson, if you always. .h.i.t as full and well, you"ll be an expert torpedoist."
"Why, it"s nothing but holding the nose of your own boat full on the other craft, amidships, and the torpedo itself does the rest," uttered the young submarine skipper.
"That"s it," nodded Lieutenant Danvers. "But, when you"re below the surface, the problem becomes a harder one."
"But then I"d come up enough to use the periscope, and get the bearings of the enemy"s vessel," declared Benson. "Then I"d drop below, using the compa.s.s for direction, and the number of motor revolutions to give me the knowledge of distance traveled."
"That"s just the way it is done," agreed Danvers. "After all, it"s just a matter of accurate boat handling, and being able to judge distances by the eye alone. And now, Mr. Benson, if you"ll run over yonder, carefully, we"ll pick up the dummies. After that, we"ve got to make as good a shot, with a real torpedo, and sink the scow."
"And, if you don"t, sir--?" smiled the young submarine skipper.
"Then we"ll be guilty of poor shooting, and have to try the second loaded torpedo," replied the naval officer. "If we miss with the second, then we"ll have to contrive either to tow the scow, or to sink her somehow. If either of the loaded torpedoes fails to explode, we"ll have to pick it up, at all hazards. If we left a loaded torpedo floating on the surface of the water, here in the paths of coast navigation, it would sink the first ship that struck the war-head of the torpedo."
The sea, by this time, was rough and whitecapped, and a brisk wind was blowing down from the north-east. It was no easy task to get a rope around first one dummy torpedo, and then the other. Yet at last this was done, and the heavy objects were hoisted aboard and stored below.
"Now, we"ll get off and sink the scow, before dark," muttered Lieutenant Danvers.
"Are you going to let me fire the torpedo at her, sir?" demanded Skipper Jack Benson, eagerly.
"If you feel sure you can do it," replied the naval officer. "For that matter, if you fail, there"ll be one loaded torpedo left, and I can take the second shot."
