CHAPTER VI.
AN UNEXPECTED RESCUE.
Sixty's unprovoked and murderous attack on Matt had been made with suchbrutal suddenness that the king of the motor boys had had no chanceto defend himself. Before he fairly realized what had happened he wasunder the water and fighting his way upward to the surface. Had he notbeen such a good swimmer the weight of his clothing would have draggedhim down and rendered his case hopeless. He was seriously handicapped,as it was, and when he gained the top of the water he was thankful tofind a life-preserver bobbing and ducking beside him.
How the life-preserver happened to be there he did not know, but heseized hold of it gratefully and allowed it to support him in thetumbling waves. By that time the _Santa Maria_ was far in the distance,but there was a commotion on her decks which indicated that the cry of"Man overboard!" was receiving a prompt response. The sharp orders ofthe officer of the deck, the cries of excited passengers, and even thejingle of the engine-room bell came distinctly to the ears of the youthin the water.
Matt, although still bewildered, congratulated himself on escaping theswiftly-revolving screw. He had been thrown from the ship near thestern, and it was a piece of luck that the suction had not drawn himunder the sharp propeller-blades.
Buffeted by the waves, Matt swung back and forth in the water andwatched while the boat was lowered. Dick and Carl were in the boat, andthere were two sailors at the oars. Dick, at the bow, was coiling apiece of rope in his hands, making ready for a cast as soon as the boatshould come near enough.
Matt, his eyes fastened on the boat, gave no attention to the expanseof water in the other direction. Suddenly he heard a cry, coming frombehind him, and turned his head. His amazement was complete when he sawa submarine rolling amid the waves. The mystery of the glistening redspeck which had claimed his attention from the steamer was explained.It was the round periscope ball of the _Grampus_!
Some one--Matt could not see distinctly, for the spindrift was in hiseyes--was half out of the conning tower of the submarine.
"Come aboard of us, Matt!" shouted the man, whirling a rope about hishead and letting it fly.
The youth's ears were filled with the _poppety-pop_ of the submarine'smotor, but he heard the request. He could only guess how the submarinehappened to be there, and guesses were useless, for he would soon betold everything about the queer situation.
Motor Matt grabbed at the rope as it was thrown to him by the man inthe submarine.
As he hauled himself toward the _Grampus_, hand over hand, he saw thatthe man in the conning tower was Townsend, or Captain Nemo, Jr., as hepreferred to be called when afloat.
Presently the young motorist was hauling himself up on the slipperydeck of the submarine.
"Are you all right, Matt?" cried Captain Nemo, Jr.
"All right, captain," answered Matt, "except that I'm as wet as adrowned rat and can hardly understand why I was thrown from thesteamer."
"You were thrown overboard?" demanded the captain.
"Yes; by your man, Sixty."
"_My_ man? I don't understand you. But we'll let that go for now. Dickand Carl are in that boat yonder. Shall we take them aboard?"
"I'd like to, sir, but we have some luggage on the _Santa Maria_ andthe boys had better go back after it."
"Tell them to get the luggage and that we'll stand by to take themoff." Nemo, Jr., threw a hasty look around at the sky, which wasrapidly becoming overcast. "Ask them to hurry," he added, "for we'll bein for dirty weather before long and we must get them on the _Grampus_before the storm comes down on us."
The rowboat by then had drawn as close to the submarine as safety wouldpermit. The two sailors were lying on their oars and gazing at thecraft in astonishment, while the rail of the steamer was crowded withpassengers and crew, all staring at the strange scene going forwardthere in the waters of the gulf.
"Ahoy, Dick!" shouted Matt.
"Ahoy, yourself, old ship!" roared Dick. "That's the _Grampus_, I takeit?"
"Yes. Captain Nemo, Jr., is going to take you and Carl aboard. Go backto the _Santa Maria_ and get our traps. Be quick about it, for theweather is threatening."
"Ay, ay," cried Dick heartily, "and it's glad I am to leave the oldhooker."
Dick dropped down in the boat and the sailors fell-to on the oars.
"Come inside, Matt," called Captain Nemo, Jr. "I'll get out of the wayand make room for you."
The captain disappeared downward, and Matt climbed over the rim of theconning tower and quickly descended the iron ladder.
In a square chamber called the periscope room, at the foot of theladder, Matt found the captain and Cassidy waiting for him. Eachgrasped his hand. There was only a moment for congratulations.
"Up into the tower with you, Cassidy," called the captain, "and keepwatch for Dick and Carl. We're going to take them on as soon as theypick up their belongings."
"Ay, ay, sir," answered Cassidy, "I heard your talk with Matt, andMatt's talk with the fellows in the boat."
Cassidy disappeared up the ladder and Matt dropped down on a locker andbegan pulling off his water-logged shoes.
"I've got a dry suit in my grip," said he, "and when the boys get hereI'll slide into a more comfortable rig."
"And Sixty threw you overboard!" muttered Nemo, Jr., a black frowncrossing his face. "The murderous scoundrel! I have long known him as adesperate man, but I would hardly have believed him capable of such amove as that! What was his reason?"
"That's more than I know."
"You mean to say that you don't know what his motive was for attemptingsuch a high-handed piece of work?"
"That's exactly what I mean, captain."
"Did any one see him?"
"Only his niece--and yours."
Captain Nemo, Jr.'s, amazement increased.
"_My_ niece?" he echoed. "I have no niece."
"Is your real name Harris, Captain?"
"No, certainly not."
"And Sixty isn't your brother-in-law?"
The captain flung up his hands.
"I should hope not! Where did you get all this queer misinformation?"
"From the girl who called herself Sadie Harris, and who said she was aniece of yours."
"You and your friends have been badly fooled, Matt," said the captain."We must probe to the bottom of this and----"
Just at that moment the _Grampus_ gave a wild roll, nearly upsettingCaptain Nemo, Jr., and almost throwing Matt from the locker. A bucketof water came sloshing down the conning-tower hatch.
"The squall's hit us!" roared Cassidy. "The weather's so thick withrain and flying scud I can't see the steamer."
"Did the boys get aboard?"
"Yes, and they've had time to get back into the whaleboat again, butthere's been some sort of a hitch."
The _Grampus_ was rolling and wallowing frightfully, and it seemed attimes as though she must surely turn turtle. The slap of waves on hersteel sides and against the conning tower caused a thunderous noise toecho through the boat.
"Close the hatch, and come down, Cassidy!" shouted the captain."We'll have to submerge her, and try to pick up the steamer with theperiscope."
Cassidy could be heard clamping down the hatch. While he was comingdown the ladder, the captain turned to one of the speaking tubes thatentered the periscope room.
"Let the water into the ballast tanks, Clackett!" he called. "Aten-foot submergence. Slow speed ahead, Gaines," he added throughanother tube. "Keep her south by west, Cassidy," said he to the mate.
"South by west it is, sir," answered Cassidy, posing himself by a smallbinnacle and laying hands on a steering wheel.
From a distance Matt heard the old familiar rhythm of the gasolinecylinders. There was a splashing as water poured into the ballasttanks, followed by a very perceptible sinking motion. The frightfulwallowing and pitching ceased to a great extent, and the _Grampus_ hungon a fairly even keel.
"Ten feet of submergence, cap'n!" came from a speaking tube sodistinctly that it almos
t seemed as though the speaker was in theperiscope room.
"Very good, Clackett," replied the captain. "Hold her so. Now, Matt,"the captain went on, "we'll see what the periscope has to show us."
The hollow steel mast of the periscope, contrived with powerfulreflectors, terminated in a hood that swung above a table.
Captain Nemo, Jr., pushed aside a fold of the hood and he and Mattlooked down on the highly-polished mirror that formed the top of thetable.
A stormy scene lay under their eyes. Their horizon was narrowed to onlya few yards by rain and spray, but within this brief radius they got asight of raging waves and a fierce tumult of waters. Now and again thescene was blotted out for a moment as the periscope ball was drenchedby a comber.
"We can't take the boys off now, captain," said Matt.
"It would be impossible in this sea," answered the captain. "I was notlooking for the squall to hit us so soon. We'll try and follow the_Santa Maria_, however, and take them off later."
"How can you follow her when you can't see her?"
"We know her track, and we'll follow her by compass."
The wild roaring of wind and sea came to those in the _Grampus_ like adull murmur, and the submarine's rocking, at a ten-foot submergence,was proof of the power the elements must be showing on the surface.
Both Matt and the captain kept their eyes constantly on the table top,then, abruptly, Matt gave a gasp and caught at the table to supporthimself.
"Look!" he cried. "Captain--the boat----"
But Captain Nemo, Jr.'s, startled eyes had already seen what Matt hadbeheld. This was a whaleboat tossed wildly on the crest of a huge waveadrift, and with Carl and Dick clinging desperately to the oars.
Only Matt's two chums were in the boat. The captain whirled to one ofthe tubes.
"Turbines at work, Clackett!" he shouted; "quick, on your life. Emptythe tanks and get us back to the surface! Reverse your engine, Gaines,"he added through another tube.
Matt, still clinging to the table, stared down on its polished top. Thedrifting whaleboat, with his two chums, had vanished as quickly as ithad appeared.
