+<h2>CHAPTER I</h2>
+
+<h3>WILL THE SHIP WORK?</h3>
+
+
+<p>"Hand me that wrench, Mark," called Professor Amos Henderson to a boy
+who stood near some complicated machinery over which the old man was
+working. The lad passed the tool over.</p>
+
+<p>"Do you think the ship will work, Professor?" he asked.</p>
+
+<p>"I hope so, Mark, I hope so," muttered the scientist as he tightened
+some bolts on what was perhaps the strangest combination of apparatus
+that had ever been put together. "There is no reason why she should not,
+and yet&mdash;"</p>
+
+<p>The old man paused. Perhaps he feared that, after all, the submarine
+boat on which he had labored continuously for more than a year would be
+a failure.</p>
+
+<p>"Is there anything more I can do now?" asked Mark.</p>
+
+<p>"Not right away," replied the professor, with<span class='pagenum'><a name="Page_2" id="Page_2">[2]</a></span>out looking up from the
+work he was doing. "But I wish you and Jack would be around in about an
+hour. I am going to start the engine then, and I'll need you. If you see
+Washington outside send him to me."</p>
+
+<p>Mark left the big room where the submarine boat had been in process of
+construction so long. Outside he met a boy about his own age, who was
+cleaning a rifle.</p>
+
+<p>"How's it going, Mark?" asked this second youth, who was rather fat,
+and, if one could judge by his face, of a jolly disposition.</p>
+
+<p>"The professor is going to try the engine in about an hour," replied
+Mark. "We must be on hand."</p>
+
+<p>"I'll be there all right. But if there isn't anything else to do, let's
+shoot at a target. I'll bet I can beat you."</p>
+
+<p>"Bet you can't. Wait 'till I get my gun."</p>
+
+<p>"Now don't yo' boys go to disportin' yo'seves in any disproportionable
+anticipation ob transposin' dem molecules of lead in a contigious
+direction to yo' humble servant!" exclaimed a colored man, coming from
+behind the big shed at that moment, and seeing Mark and Jack with their
+rifles.</p>
+
+<p>"I s'pose you mean to say, Washington," remarked Jack, "that you don't
+care to be shot at. Is that it?"<span class='pagenum'><a name="Page_3" id="Page_3">[3]</a></span></p>
+
+<p>"Neber said nuffin truer in all yo' born days!" exclaimed Washington
+earnestly. "De infliction ob distress to de exterior portion ob&mdash;"</p>
+
+<p>"The professor wants you," interrupted Mark, cutting off the colored
+man's flow of language.</p>
+
+<p>"Yo' mind what I tole yo'," Washington muttered as he hurried into the
+work room.</p>
+
+<p>Soon the reports of rifles indicated that the boys were trying to
+discover who was the best shot, a contest that waged with friendly
+interest for some time.</p>
+
+<p>The big shed, where the submarine ship was being built, was located at a
+lonely spot on the coast of <ins title="Transcriber's Note: original reads 'Main'">Maine</ins>. The nearest town was Easton, about
+ten miles away, and Professor Henderson had fixed on this location as
+one best suited to give him a chance to work secretly and unobserved on
+his wonderful invention.</p>
+
+<p>The professor was a man about sixty-five years old, and, while of simple
+and kindly nature in many ways, yet, on the subjects of airships and
+submarines, he possessed a fund of knowledge. He was somewhat queer, as
+many persons may be who devote all their thoughts to one object, yet he
+was a man of fine character.</p>
+
+<p>Some time before this story opens he had invented an electric airship in
+which he, with Mark Sampson, Jack Darrow and the colored man,<span class='pagenum'><a name="Page_4" id="Page_4">[4]</a></span>
+Washington White, had made a trip to the frozen north.</p>
+
+<p>Their adventures on that journey are told of in the first volume of this
+series, entitled, "Through the Air to the North Pole, or, The Wonderful
+Cruise of the <i>Electric Monarch</i>."</p>
+
+<p>The two boys, Mark then being fifteen and Jack a year older, had met the
+professor under peculiar circumstances. They were orphans, and, after
+knocking about the world a bit, had chanced to meet each other. They
+agreed to seek together such fortune as might chance to come to them.</p>
+
+<p>While in the town of Freeport, N. Y., they were driven away by a
+constable, who said tramps were not allowed in the village. The boys
+jumped on a freight train, which broke in two and ran away down the
+mountain, and the lads were knocked senseless in the wreck that
+followed.</p>
+
+<p>As it chanced Professor Henderson had erected nearby a big shop, where
+he was building his airship. He and Washington were on hand when the
+wreck occurred and they took the senseless boys to the airship shed.</p>
+
+<p>The boys, after their recovery, accepted the invitation of the professor
+to go on a search for the north pole. As the airship was about to start
+Andy Sudds, an old hunter, and two men, Tom<span class='pagenum'><a name="Page_5" id="Page_5">[5]</a></span> Smith and Bill Jones, who
+had been called in to assist at the flight, held on too long and were
+carried aloft.</p>
+
+<p>Somewhat against their will the three latter made the trip, for the
+professor did not want to return to earth with them.</p>
+
+<p>The party had many adventures on the voyage, having to fight savage
+animals and more savage Esquimaux. They reached the north pole, but in
+the midst of such a violent storm that the ship was overturned, and the
+discovery of the long-sought goal availed little. After many hardships,
+and a fierce fight to recover the possession of the ship, which had been
+seized by natives, the adventurers reached home.</p>
+
+<p>Since then a little over a year had passed. The professor, having found
+he could successfully navigate the air, turned his attention to the
+water, and began to plan a craft that would sail beneath the ocean.</p>
+
+<p>To this end he had moved his machine shop to this lonely spot on the
+Maine coast. The two boys, who had grown no less fond of the old man
+than he of them, went with him, as did Washington White, the negro, who
+was a genius in his way, though somewhat inclined to use big words, of
+the meaning of which he knew little and cared less.<span class='pagenum'><a name="Page_6" id="Page_6">[6]</a></span></p>
+
+<p>Andy Sudds, the old hunter, had also been induced to accompany the
+professor.</p>
+
+<p>"I hunted game up north and in the air," said Andy, "and if there's a
+chance to shoot something under the water I'm the one to do it."</p>
+
+<p>Needing more assistance than either the boys, Andy or Washington could
+give, the professor had engaged two young machinists, who, under a
+strict promise never to divulge any of the secrets of the submarine, had
+labored in its building.</p>
+
+<p>Now the queer craft was almost finished. As it rested on the ways in the
+shed, it looked exactly like a big cigar, excepting that the top part
+was level, forming a platform.</p>
+
+<p>The ship, which had been named the <i>Porpoise</i>, was eighty feet long, and
+twenty feet in diameter at the largest part. From that it tapered
+gradually, until the ends were reached. These consisted of flattened
+plates about three feet in diameter, with a hole in the center one foot
+in size.</p>
+
+<p>Weary months of labor had been spent on the <i>Porpoise</i>, until now it was
+almost ready for a trial. The professor had discovered a new method of
+propulsion. Instead of propellers or paddle-wheels, he intended to send
+his craft ahead or to the rear, by means of a water cable.</p>
+
+<p>Through the entire length of the ship ran a round hole or shaft, one
+foot in diameter. Within<span class='pagenum'><a name="Page_7" id="Page_7">[7]</a></span> this was an endless screw worked by powerful
+engines. With a working model the professor had demonstrated that when
+the endless screw was revolved it acted on the water just as another
+sort of screw does in wood. The water coming in through the shaft served
+as a rope, so to speak, and the screw, acting on it, pulled the craft
+ahead or to the rear, according to the direction in which the screw was
+revolved.</p>
+
+<p>The submarine was a wonderful craft. It contained a powerful engine,
+electric motors and dynamos, and machinery of all kinds. The engine was
+a turbine, and steam was generated from heat furnished by the burning of
+a powerful gas, manufactured from sea water and chemicals. So there was
+no need to carry a supply of coal on the ship.</p>
+
+<p>The interior of the vessel was divided into an engine-room, a kitchen,
+combination dining-room and parlor, bunk rooms, and a conning tower, or
+place for the <ins title="Transcriber's Note: original reads 'stearsman'">steersman</ins>.</p>
+
+<p>While the boys had been shooting at the target the professor and
+Washington had been putting the finishing touches to the engine,
+tightening nuts here and screwed up bolts there.</p>
+
+<p>"I guess that will do," remarked the old inventor. "Call the boys,
+Washington."</p>
+
+<p>The colored man went to the door and gave<span class='pagenum'><a name="Page_8" id="Page_8">[8]</a></span> three blasts on a battered
+horn that hung from a string.</p>
+
+<p>"Coming!" called Mark, as he and Jack ceased their marksmanship contest
+and approached the shed.</p>
+
+<p>"Now boys, we'll see if she works so far," said the professor. "If she
+does, we'll give her a trial under water."</p>
+
+<p>At the inventor's directions the boys started the gas to generating from
+the chemicals. Soon the hissing of steam told them that there was power
+in the boiler.</p>
+
+<p>The professor entered the engine-room of the submarine. He looked over
+the various wheels, levers, handles, gages and attachments, satisfying
+himself that all were in proper shape and position.</p>
+
+<p>"Three hundred pounds pressure," he muttered, glancing at the steam
+indicator. "That ought to be enough. Are you all ready, boys?"</p>
+
+<p>"All ready!" cried Jack.</p>
+
+<p>Of course the test was only one to see if the engine worked, for the
+boat could not move until in the water.</p>
+
+<p>The professor opened a valve. The steam filled the turbine with a hiss
+and throb. The <i>Porpoise</i> trembled. Then, with a cough and splutter of
+the exhaust pipes, the engine started. Slowly it went at first, but, as
+the professor admitted more steam,<span class='pagenum'><a name="Page_9" id="Page_9">[9]</a></span> it revolved the long screw until it
+fairly hummed in the shaft.</p>
+
+<p>"Hurrah! It works!" cried Mark.</p>
+
+<p>"It does!" chimed in Jack.</p>
+
+<p>"Gollyation! She suttinly am goin'!" yelled Washington.</p>
+
+<p>"I think we may say it is a success," said the professor calmly, yet
+there was a note of exultation in his voice.</p>
+
+<p>"Now that you've got her started, when are you goin' to put her in the
+water an' scoot along under the waves?" asked Andy Sudds.</p>
+
+<p>"In about a week," replied the professor.</p>
+
+<p>"And where are you goin' to head for?" went on the hunter.</p>
+
+<p>"We're going under the ocean to the south pole!" exclaimed the inventor,
+as he shut off the engine.<span class='pagenum'><a name="Page_10" id="Page_10">[10]</a></span></p>

+<p>"The south pole?" exclaimed Mark.</p>
+
+<p>"Way down dat way!" cried Washington.</p>
+
+<p>"Can you do it?" asked Jack.</p>
+
+<p>"That remains to be seen," replied the professor, answering them all at
+once. "I'm going to try, at any rate."</p>
+
+<p>"Hurrah!" yelled Mark. "It will be better than going to the north pole,
+for we will be in no danger of freezing to death."</p>
+
+<p>"Don't be so sure of that," interrupted the professor. "There is more
+ice at the south pole than at the north, according to all accounts. It
+is a place of great icebergs, immense floes and cold fogs. But there is
+land beyond the ice, I believe, and I am going to try to find it."</p>
+
+<p>"It will be a longer voyage than to the north pole," said Jack.</p>
+
+<p>"Jest de same," argued Washington, "de poles am at each end ob de
+world."</p>
+
+<p>"Yes, but we're quite a way north of the equator now, and we'll have to
+cross that before we<span class='pagenum'><a name="Page_11" id="Page_11">[11]</a></span> will be half way to the south pole," explained
+Jack. "But I guess the <i>Porpoise</i> can make good time."</p>
+
+<p>"If the engine behaves under water as well as it did just now, we'll
+skim along," said the professor.</p>
+
+<p>"And so you figure there's land down there to the south, do you?" asked
+old Andy.</p>
+
+<p>"I do," replied the inventor. "I can't prove it, but I'm sure there is.
+I have read all the accounts of other explorers and from the signs they
+mention I am positive we shall find land if we ever get there. Land and
+an open sea."</p>
+
+<p>"And other things as well," muttered Andy, yet neither he nor any of
+them dreamed of the terrible and strange adventures they were to have.</p>
+
+<p>The next few days were busy ones. Many little details remained to
+perfect in connection with the ship, and a lot of supplies and
+provisions had to be purchased, for the professor was determined to get
+all in readiness for the trip under the water. He believed firmly that
+his ship would work, though some of the others were not so positive.</p>
+
+<p>"We'll put her into the water to-morrow," announced the inventor after
+supper one night. "Everything is complete as far as I can make it, and
+the only thing remaining is to see if she will float, sink when I want
+her to, and, what is most<span class='pagenum'><a name="Page_12" id="Page_12">[12]</a></span> important, rise to the surface again. For,"
+he added with a twinkle in his eye, "anybody can make a ship that will
+sink, but it isn't every one who can make one that will come to the
+surface again."</p>
+
+<p>"Golly! I hope dis chile ain't goin' to git in no subicecream ship
+what'll stay down under de water so de fishes gits him!" exclaimed
+Washington, opening his eyes wide. "Dat's worser dan freezin!"</p>
+
+<p>"Can't you swim?" asked Mark with a wink at Jack.</p>
+
+<p>"Co'se I can swim, boy. I can swim like a starfish, but I can't wif ten
+thousand tons of a subicecream ship on my back."</p>
+
+<p>"A sub-ice-cream ship is a new one," commented the professor with a
+smile. "It's a submarine, Washington."</p>
+
+<p>"I can't see no difference," persisted the colored man. "Subicecream am
+good enough for me."</p>
+
+<p>That night Mark and Jack were thinking so much of the proposed test of
+the ship the next day that they each dreamed they were sailing beneath
+the waves, and Jack woke Mark up by grabbing him about the neck during a
+particularly vivid part of the vision.</p>
+
+<p>"What's the matter?" inquired Mark, sleepily.<span class='pagenum'><a name="Page_13" id="Page_13">[13]</a></span></p>
+
+<p>"I thought the ship turned over and spilled me out and I was drowning,"
+explained Jack. "I grabbed the first thing I got hold of and it happened
+to be you."</p>
+
+<p>"Well, as long as you're safe you can go to sleep again," said Mark. "I
+dreamed I was chasing a whale with the <i>Porpoise</i>."</p>
+
+<p>The boys were up early the next morning, and found the professor and
+Washington before them. The inventor was inspecting the track which had
+been built from the shed down to the water's edge to enable the
+<i>Porpoise</i> to slide into the ocean.</p>
+
+<p>With him were the two machinists, Henry Watson and James Penson. They
+had been busy since daylight making the ways secure.</p>
+
+<p>"She goes in after breakfast," announced the professor, "and I'm going
+to let you christen her, Washington."</p>
+
+<p>"Me? I neber christened a ship," objected the colored man.</p>
+
+<p>"Nothing like learning," remarked Mr. Henderson.</p>
+
+<p>"Has you got the bottle ob wine?" asked Washington.</p>
+
+<p>"I guess soda water will do," said the inventor. "Now look sharp, boys.
+Get your breakfasts and we'll see if the ship will come up to our
+expectations."<span class='pagenum'><a name="Page_14" id="Page_14">[14]</a></span></p>
+
+<p>No one lingered over the meal. When it was finished the professor gave
+Washington a few instructions about breaking the bottle over the nose of
+the <i>Porpoise</i> as she slid down to the water, for there was no bow to
+such a queerly shaped vessel as the submarine.</p>
+
+<p>At last all was in readiness. The two machinists knocked away the last
+of the retaining blocks and eased the ship slightly down the
+well-greased timbers of the ways.</p>
+
+<p>"There she goes!" cried the professor. "Break the bottle, Washington!"</p>
+
+<p>"In de name ob de Stars an' Stripes, in de name of liberty, de home of
+the free an' de land ob de brave, I names yo' <i>Mrs. Porpoise!</i>" cried
+the colored man, but he was so long getting the words out, and so slow
+in swinging the bottle of soda, that the ship was quite beyond his reach
+when he had finished his oration. He was not to be outdone, however,
+and, with a quick movement he hurled the bottle at the moving ship. It
+struck the blunt nose squarely, and shivered to pieces.</p>
+
+<p>"Three cheers for de south pole!" yelled Washington, and the others
+joined in.</p>
+
+<p>The next instant the <i>Porpoise</i> was riding the waves of the little bay,
+dancing about as lightly as a cork, though, from the nature of her
+construction, she was quite low in the water, only about<span class='pagenum'><a name="Page_15" id="Page_15">[15]</a></span> three feet of
+freeboard showing where the platform was located.</p>
+
+<p>"Well, she floats, anyhow," remarked the professor. "Row out and fasten
+cables fore and aft," he went on, turning to the two machinists. In a
+few minutes the <i>Porpoise</i> was fastened to a small dock with strong
+ropes the two young men had carried out to her in rowboats.</p>
+
+<p>"We will go aboard in a little while," the professor said. "I am anxious
+to see if she rides on an even keel and how the sinking tanks work."</p>
+
+<p>Aided by the boys, he and Washington carried on board a number of tools
+and appliances. Then, with the two machinists, they all descended into
+the interior of the craft through the small manhole in the middle of the
+deck or platform.</p>
+
+<p>Inside the <i>Porpoise</i>, the greater part of which was below the surface
+of the waves and consequently in darkness, the professor switched on the
+electric lights and then he proceeded to get up steam.</p>
+
+<p>The propelling power of the craft has already been described. In order
+to make the ship sink beneath the water all that was necessary was to
+incline the rudder and open certain valves in the four tanks, when the
+water, rushing in, would sink her. There was a tank on either side, and
+one each fore and aft. If it was desired to sink<span class='pagenum'><a name="Page_16" id="Page_16">[16]</a></span> straight down all four
+tanks were filled at once. If the professor wanted to descend slanting
+either to the front or back, only one of the end tanks was filled,
+according to the direction desired. The deflecting rudder also aided
+greatly in this movement.</p>
+
+<p>To cause the ship to rise the tanks were emptied of the water by means
+of powerful pumps. The filling of the tanks, as well as the emptying of
+them, the starting or stopping of the engine that moved the boat, as
+well as the control of most of the important machinery on the craft
+could be accomplished from the conning or <ins title="Transcriber's Note: original reads 'stearing'">steering</ins> tower, as well as
+from the engine-room.</p>
+
+<p>There were numerous gages to tell the depth to which the ship had sunk,
+the steam pressure, density of the water, and other necessary details.</p>
+
+<p>There were dynamos to make light, motors to run the pumps, and a great
+storage battery, so that in case of a breakdown to the turbine engine
+the craft could be run entirely by electricity for a time.</p>
+
+<p>The cooking was all done by this useful current, and all that was
+necessary to make a cup of coffee or fry a <ins title="Transcriber's Note: original reads 'beeksteak'">beefsteak</ins> was to turn a small
+switch of the electric stove.</p>
+
+<p>The professor was busy over the machine for generating gas, that
+furnished the heat to create steam. Soon a hissing told that it was
+working.<span class='pagenum'><a name="Page_17" id="Page_17">[17]</a></span> In a few minutes the hum and throb of the engine told that it
+was ready to start.</p>
+
+<p>"We are only going down a little way," the professor said, "and only
+going to travel a short distance under water for the first time. I think
+there is no danger, but if any of you want to back out, now is your
+chance."</p>
+
+<p>No one seemed inclined to withdraw, though Mark said afterward he
+thought Washington got as pale as it is possible for a colored man to
+get.</p>
+
+<p>"We will all put on life preservers," the inventor went on, "and one of
+you will be stationed near the emergency exit. In case anything goes
+wrong, and I cannot make the ship rise, by pulling the lever the top of
+the craft will be forced off, and, we can at least save our lives. I
+think we are all ready now. Mark, you clamp down the manhole cover, and
+Jack, after you close the conning tower station yourself at the
+emergency lever after we have donned the life preservers."</p>
+
+<p>The cork jackets were adjusted and Mark clamped the manhole cover on.
+The professor took one last look at the various levers and handles, and
+then turned the wheel that admitted water to all four tanks. There was a
+hissing sound as the sea water rushed in, and the <i>Porpoise</i> gave a
+sudden lurch.</p>
+
+<p>Then they could all feel the submarine sinking.<span class='pagenum'><a name="Page_18" id="Page_18">[18]</a></span> Down and down she went.
+Would she ever stop? Would the professor be able to raise her again?
+There were questions that troubled everyone.</p>
+
+<p>Down and down the craft sunk, until by the gage it was indicated that
+she was twenty feet below the surface. Then the professor shut off the
+inrush of water and the <i>Porpoise</i> floated away below the surface of the
+waves.</p>
+
+<p>There was a clicking sound and all the lights went out. The boys and
+Washington gave a gasp of terror. What did the sudden blackness mean.</p>
+
+<p>"Open the side windows," called the professor's voice, and the two
+machinists obeyed. Heavy steel doors that covered plate glass windows in
+either side of the craft were pulled back, and a cry of astonishment
+broke from the boys.</p>
+
+<p>They looked out and saw staring in at them, so close it seemed that they
+could touch them, scores of fishes that looked in through the glass
+bull's-eyes.</p>
+
+<p>For the first time they realized that they were in the depths of the
+ocean.<span class='pagenum'><a name="Page_19" id="Page_19">[19]</a></span></p>

+<h2>CHAPTER III</h2>
+
+<h3>RUNNING DOWN A WARSHIP</h3>
+
+
+<p>"How do you like it?" asked the professor.</p>
+
+<p>"Great!" exclaimed Jack.</p>
+
+<p>"Fine!" cried Mark.</p>
+
+<p>"It am simply coslostrousness!" exploded Washington. "'Nebber in all my
+born days did I eber expansionate on such a sight!"</p>
+
+<p>"Wish I had a fishing pole and line," remarked Andy Sudds. "There's some
+pretty nice <ins title="Transcriber's Note: original reads 'speciments'">specimens</ins> out there."</p>
+
+<p>"You'll see better ones than those before we finish our trip to the
+pole," remarked the professor. "Now we will try moving forward. I am
+going into the conning tower."</p>
+
+<p>He turned on the lights once more, but the boys begged him to shut them
+off, as they could see out into the ocean when the interior of the ship
+was in darkness. So the professor obliged them.</p>
+
+<p>In the tower he switched on the powerful searchlight that illuminated
+the path in front of him. Then he started the engine, slowly at first,
+and gradually increasing the speed. The <i>Porpoise</i><span class='pagenum'><a name="Page_20" id="Page_20">[20]</a></span> forged ahead, riding
+as evenly as an ordinary ship does on the surface.</p>
+
+<p>The professor <ins title="Transcriber's Note: original reads 'steared'">steered</ins> her about in a large circle, bringing her back to
+the starting point. She worked as smoothly as if she had been used to
+under-water service for years.</p>
+
+<p>"Now," said the inventor, "we will see if we can go up to the surface
+again," and there came a little note of anxiety into his voice. He
+slowed down the engine and started the powerful pumps that were to empty
+the tanks. For a moment there was a feeling of terror in the hearts of
+all. Would the pumps work?</p>
+
+<p>Then, slowly but surely, those aboard the <i>Porpoise</i> felt her beginning
+to rise. Up and up she went as the tanks were emptied and the ship
+lightened.</p>
+
+<p>Then, with a bounce like a rubber ball, the submarine shot upward to the
+surface and lay undulating on the waves caused by her emergence from the
+depths.</p>
+
+<p>"Hurrah!" shouted Jack. "We're all right!"</p>
+
+<p>"We shore am!" exclaimed Washington.</p>
+
+<p>"It's a success!" Professor Henderson almost whispered. "The pumps
+worked. The <i>Porpoise</i> has fulfilled my greatest expectations!"</p>
+
+<p>Then he steered the ship back to the dock, where she was moored, and the
+adventurers disembarked.<span class='pagenum'><a name="Page_21" id="Page_21">[21]</a></span></p>
+
+<p>"One or two little details to attend to, and we'll be ready for the
+great trip," remarked the professor. "I want to give her a little harder
+trial before I trust her, though she seems to be first-rate."</p>
+
+<p>They all went back to the combined machine shop and cabin, where they
+had lived during the building of the submarine. Dinner was prepared and,
+after the meal the two machinists approached the professor.</p>
+
+<p>"I don't suppose you need us any more," remarked Henry Watson. "The ship
+is finished as far as we can do anything, and we may as well leave now.
+We have an offer to go to work in an electrical shop."</p>
+
+<p>"I haven't said much to you about my plans," the professor replied, "but
+if you would like to remain in my employ, I can promise you an
+interesting trip."</p>
+
+<p>"Thank you, but I prefer to work above ground," said James Pensen. "You
+have been very kind to us, and we would do anything we could for, but we
+don't want to take any long under-ocean trips if we can help it."</p>
+
+<p>"Very well," answered the professor, though he seemed disappointed. "I
+will pay you what I owe you and you can go."</p>
+
+<p>For some time after the departure of the two young machinists the
+inventor seemed worried.<span class='pagenum'><a name="Page_22" id="Page_22">[22]</a></span></p>
+
+<p>"Did you count on them staying with you?" asked Mark.</p>
+
+<p>"I rather hoped they would," replied Mr. Henderson. "We need two more
+hands if we are to make the trip. They need not be machinists, but we
+will have to have someone, and I don't like to get strangers. They might
+talk too much about the ship."</p>
+
+<p>At that instant there came a rap on the door. Washington answered it.</p>
+
+<p>"Yas sir, Perfesser Henderson done lib here," he replied, in answer to a
+question from some one. "But he am bery busy jest at de present
+occasioness an' he'll be most extremely discommodated if yo' obtrude yo'
+presence on him at de conglomeration ob de statutory limitations, which
+am to say right now. Come again!"</p>
+
+<p>"It's the same old Washington!" said someone outside, laughing heartily.
+"Just you tell the professor we want to see him most particular."</p>
+
+<p>At the sound of the voice the professor started and Mark and Jack
+wondered where they had heard it before.</p>
+
+<p>"Show the gentlemen in, Washington," called the inventor.</p>
+
+<p>"Dere's two ob 'em," objected the colored man.</p>
+
+<p>"Show them both in, then."</p>
+
+<p>Washington opened the door of the cabin, and in<span class='pagenum'><a name="Page_23" id="Page_23">[23]</a></span> came two men, who
+seemed much amused over something.</p>
+
+<p>"What can I do for you?" asked the professor, in rather a sharp voice.</p>
+
+<p>"He don't know us either, Tom," remarked the taller of the two.</p>
+
+<p>"If it ain't Bill Jones and Tom Smith!" exclaimed Andy Sudds. "Wa'al
+I'll be horn swoggled. Where'd ye come from?"</p>
+
+<p>"Right from the farm," replied Bill. "And we've had a hard job locating
+you. I guess Washington didn't know us since we raised beards," and Bill
+stroked his wealth of brown whiskers.</p>
+
+<p>"And I guess we sort of fooled the professor," went on Bill, "eh, Tom?"</p>
+
+<p>"Right!" said Tom. "You see," he went on, "the farming business is
+almost over, as its coming on fall now, so Bill and I thought it would
+be a good time to hunt up the professor. We heard he was down in this
+neighborhood so we come by easy stages. We didn't have any time to stop
+and make our toilets, hence our beards."</p>
+
+<p>"You've come at the right time," remarked the inventor, as he came
+forward to welcome the two young men. "Do you remember the trip you made
+with me to the north pole?"</p>
+
+<p>"I guess we'll not forget it in a hurry," replied Bill.<span class='pagenum'><a name="Page_24" id="Page_24">[24]</a></span></p>
+
+<p>"That's what made us hunt you up," put in Tom. "We hoped you might have
+something similar on foot."</p>
+
+<p>"I have," answered the inventor.</p>
+
+<p>"What is it?"</p>
+
+<p>"A trip under the ocean!"</p>
+
+<p>For an instant the two young men hesitated. It was a new proposition to
+them. Yet they recalled that they had come safely back from the journey
+through the air.</p>
+
+<p>"Do you want to go along as part of the crew?" asked the inventor, after
+some further conversation.</p>
+
+<p>"You can count on me!" cried Bill.</p>
+
+<p>"And if Bill goes I'll go too!" exclaimed Tom.</p>
+
+<p>"Under the seas or over the seas, it'll <ins title="Transcriber's Note: this word missing in original text">be</ins> all one to us if Professor
+Henderson sails the ship!" went on Bill. "We'll go!"</p>
+
+<p>"Good!" ejaculated the professor. "You certainly came at just the right
+time."</p>
+
+<p>As Tom Smith and Bill Jones were hungry a hasty meal was prepared for
+them, during the eating of which they told of their experiences since
+landing from the airship. They had been on a farm until fired with a
+desire to go roving once more.</p>
+
+<p>For the next few days the professor, the boys, and the other four were
+busy making some im<span class='pagenum'><a name="Page_25" id="Page_25">[25]</a></span>provements to the <i>Porpoise</i>. Tom and Bill were much
+astonished at their first sight of the queer craft, but they soon became
+accustomed to her, and said they preferred her to the airship.</p>
+
+<p>"To-morrow we are going on a little longer trip than our first trial,"
+announced the inventor one evening. "We will be gone all day if nothing
+happens to make the stay more lengthy," he added grimly. "So,
+Washington, put plenty to eat aboard."</p>
+
+<p>A little later, when supplies had been put on the <i>Porpoise</i>, and the
+machinery well overhauled, the professor explained that he intended
+making a trip, entirely under water, from the dock in the cove to a
+point off the Massachusetts coast and return.</p>
+
+<p>Early the next morning all were aboard. To each one was assigned a
+particular station. Washington, with Mark as an assistant, was in the
+engine-room. Jack was to watch the various gages and registers to give
+warning of any danger. The professor, of course, would be in the conning
+tower and operate the craft. Andy was to be with him, to watch out, with
+his sharp eyes, for any danger that might loom up in the path of the
+searchlight. Tom and Bill were to be ready to help where needed.</p>
+
+<p>With a hissing sound the water filled the tanks and the <i>Porpoise</i> sunk
+beneath the waves. The<span class='pagenum'><a name="Page_26" id="Page_26">[26]</a></span> engine that worked the endless screw was
+started, and the threads, working on the water cable, shot the boat
+ahead.</p>
+
+<p>"We're off!" yelled Washington.</p>
+
+<p>About sixty feet below the surface the craft was sent along. Mile after
+mile was covered as shown by the patent log. The lights were turned off,
+and through the thick plate glass windows the strange inhabitants of the
+sea were observed.</p>
+
+<p>"I think I'll go a little nearer the surface," said the professor to
+Andy. The inventor started the pumps that emptied the tanks. The craft
+rose slightly.</p>
+
+<p>"Quick! Stop her!" shouted the old hunter, grasping the captain's arm.</p>
+
+<p>Something black, like a grim shadow, loomed up in the dull glare of the
+searchlight.</p>
+
+<p>"What is it?" cried the professor.</p>
+
+<p>"We're goin' to hit somethin' hard!" yelled Andy.</p>
+
+<p>"It's the hull of a ship!" exclaimed the inventor as he jammed the
+reversing lever hard over.</p>
+
+<p>It was too late. The next instant the <i>Porpoise</i>, with a shock that made
+her shiver from stem to stern, collided with the steel side of a small
+warship.<span class='pagenum'><a name="Page_27" id="Page_27">[27]</a></span></p>
+
+
+
+<hr style="width: 65%;" />
+<h2>CHAPTER IV</h2>
+
+<h3>IN THE MIDST OF FIRE</h3>
+
+
+<p>"Pull the secondary emergency lever!" cried the professor through the
+speaking tube to Washington. "We must reach the surface at once!"</p>
+
+<p>"Are we damaged?" asked Andy, scrambling to his feet, for the shock had
+knocked him down. The professor had not fallen because he clung to the
+steering wheel.</p>
+
+<p>The ship gave a sudden lurch.</p>
+
+<p>"We're sinking!" cried Bill, rushing to the conning tower from the
+engine-room.</p>
+
+<p>"That's only the action of one of the emergency levers," said the
+professor calmly. "It forces compressed air into the tanks the more
+quickly to empty them of water. I think we are safe."</p>
+
+<p>"What is it?" asked Mark, as, followed by Jack, he came forward.</p>
+
+<p>"We tried to do the torpedo act to one of Uncle Sam's ships," explained
+Andy.</p>
+
+<p>The electric lights had been switched on, and, with the <i>Porpoise</i>
+flooded with the bright beams,<span class='pagenum'><a name="Page_28" id="Page_28">[28]</a></span> those on board waited anxiously for what
+was to happen next.</p>
+
+<p>Suddenly an upward motion was experienced. The next instant the craft
+bounced out of the water and fell back in a smother of foam, shaking and
+shivering, alongside a small armored warship that was anchored about two
+miles and a half from shore.</p>
+
+<p>"Open the manhole," commanded Mr. Henderson.</p>
+
+<div class="figleft" style="width: 267px;">

+<span class="caption">A CURIOUS THRONG CROWDED TO THE RAIL OF THE WARSHIP.&mdash;Page 28.</span>
+</div>
+
+<p>Mark sprang up the iron ladder that led to the opening in the deck of
+the <i>Porpoise</i> and threw back the cams that held the heavy iron in
+place. Then he swung the cover back and stepped out on the small
+platform, followed by the professor, Andy and Jack. They looked up to
+find themselves observed by a curious throng that crowded to the rail of
+the warship.</p>
+
+
+
+<p>"What are you trying to do? Ram me with a new-fangled torpedo?" asked an
+angry voice, and a man in a gold laced uniform, who, from his importance
+plainly showed himself to be the captain of the ship, shook his fist at
+Mr. Henderson.</p>
+
+<p>"I might ask what right your ship has to get in my path," replied the
+inventor. "It was all an accident."</p>
+
+<p>"Mighty queer," muttered the naval commander. "Looks very suspicious.
+How do I know<span class='pagenum'><a name="Page_29" id="Page_29">[29]</a></span> but what you're a torpedo from some foreign nation?"</p>
+
+<p>"Because this is not a torpedo," replied Mr. Henderson. "It is a new
+submarine boat of my invention, and I was giving it a trial spin."</p>
+
+<p>"I guess you'd better come aboard and do your explaining," went on the
+captain. "I don't like the looks of things. Lower a boat!" he shouted,
+"and bring those chaps to my cabin. I want to question them."</p>
+
+<p>It did not suit Professor Henderson to have his plans upset in this
+fashion. Nor did he care to give a detailed description of his ship to
+officers of the war department. He had many valuable inventions that
+were not patented. So he determined to outwit the pompous commander of
+the cruiser.</p>
+
+<p>The noise made in preparing the small boat for lowering over the side of
+the big ship could be plainly heard.</p>
+
+<p>"Go below, all of you, and as quietly as you can," whispered Mr.
+Henderson.</p>
+
+<p>Andy, Mark and Jack obeyed. At that instant the side of the warship was
+almost deserted, for the sailors who had gathered to observe the
+<i>Porpoise</i> had gone to lower the small boat.</p>
+
+<p>No sooner had Jack, who was in the rear, disappeared through the manhole
+than the professor, with a quick jump, followed him.<span class='pagenum'><a name="Page_30" id="Page_30">[30]</a></span></p>
+
+<p>"Here! Come back!" shouted the warship's captain as he saw Mr.
+Henderson's head disappearing from view. "Come back I say!"</p>
+
+<p>But with a quick movement the inventor pulled down the manhole cover and
+clamped it. Then he sprang to the conning tower, and, with a jerk,
+opened the levers that admitted water to the tanks. The <i>Porpoise</i> began
+to sink slowly, and then more suddenly, so that, in less than a minute,
+she was out of sight beneath the waves, and the angry, gold-laced
+captain was staring in wonderment at the place where the submarine had
+been. The spot was marked only by a few bubbles and some foam.</p>
+
+<p>"I guess he'll wait some time for an explanation," spoke Mr. Henderson,
+as he started the big screw and sent the <i>Porpoise</i> ahead at a swift
+pace.</p>
+
+<p>"That was rather a narrow escape," observed Jack, standing at the foot
+of the conning tower stairs and talking to Andy and Mr. Henderson, who
+was steering.</p>
+
+<p>"It certainly was," agreed the professor. "I have not yet become used to
+seeing things very far ahead in the dimness caused by being under water.
+But we'll soon get used to it. Luckily, the <i>Porpoise</i> was not damaged
+by the shock."</p>
+
+<p>For several hours the <i>Porpoise</i> was kept on her course. She behaved
+handsomely, and nothing<span class='pagenum'><a name="Page_31" id="Page_31">[31]</a></span> excepting slight and easily remedied defects
+were found. The professor steered well out to sea, increasing both the
+forward speed and the depth to which the vessel sank. Presently the
+craft came to a stop with a little jolt.</p>
+
+<p>"What's the trouble?" asked Mark, somewhat alarmed.</p>
+
+<p>"Nothing at all," replied the professor with a smile, as he stepped out
+of the conning tower and entered the engine-room. "I thought it was time
+for dinner so I stopped the ship. We are now resting on the ocean bed,
+about half a mile below the surface. Look!"</p>
+
+<p>As he spoke he slid back the slides covering the plate glass windows.
+The boys saw that the ship rested in the midst of an immense forest of
+sea weed. Some of the stalks were as large around as trees. In and out
+among the snake-like, waving branches swam big fishes. It was a weird,
+but beautiful sight.</p>
+
+<p>"Come, Washington, serve dinner," ordered Mr. Henderson, and the colored
+man soon had a good meal prepared. Few repasts have been eaten under
+such strange circumstances.</p>
+
+<p>Desiring to be back at his secluded dock by nightfall, Captain Henderson
+soon started the <i>Porpoise</i> up again. Without any accidents the return
+trip was made and by nine o'clock the <i>Porpoise</i><span class='pagenum'><a name="Page_32" id="Page_32">[32]</a></span> rode safely at the
+dock where she had been <ins title="Transcriber's Note: original reads 'lauched'">launched</ins>.</p>
+
+<p>The night was spent in the cabin on shore. Early the next morning Mr.
+Henderson paid a visit to the ship, to make a thorough examination by
+daylight, and see if the craft had suffered any damage.</p>
+
+<p>"I think you and Mark will have to make a trip to town," he said to Jack
+at the breakfast table. "I need a new monkey wrench and some other tools
+and some small pieces of machinery. I'll give you a list of them, and
+you can bring them back in a valise, for they will be quite numerous."</p>
+
+<p>After the meal the inventor made a record of what he needed and the boys
+started off.</p>
+
+<p>"In case the machine shop does not have everything and you have to wait
+for something, you had better stay in the town all night," the captain
+of the <i>Porpoise</i> said. "It is quite a long trip and I don't want you
+traveling after dark. Put up at the hotel if you are delayed."</p>
+
+<p>Provided with money for their purchase, and a large valise in which to
+carry them, the boys started off. They had to walk two miles to where a
+trolley line was built that ran to the town of Easton, where they were
+to get the tools and parts of machinery.</p>
+
+<p>They made the trip safely and without incident. When they gave the
+machinist, to whom they had<span class='pagenum'><a name="Page_33" id="Page_33">[33]</a></span> been directed by Mr. Henderson, the list of
+the things needed, the man looked puzzled.</p>
+
+<p>"I'll have to make one piece," he said. "You'll have to wait for it.
+Can't promise it before to-morrow morning about eight o'clock."</p>
+
+<p>"That will be all right," remarked Mark. "We'll call for it then."</p>
+
+<p>So, bearing in mind Mr. Henderson's instructions, the boys engaged a
+room at the hotel, which was quite a large one, for Easton was a
+favorite summer resort and the town was filled with visitors. The lads
+strolled about the town, had their dinner, and then went for a bath in
+the surf. They retired early, for they were tired.</p>
+
+<p>In the middle of the night Mark began to dream that he was on board the
+<i>Porpoise</i> and that the submarine blew up. There was a loud noise, he
+saw a bright flash of flame, and saw rolling clouds of smoke. So vivid
+was the vision that he thought he tried to leap out of the boat, and
+awoke with a jump, to find Jack shaking him.</p>
+
+<p>"What's the matter?" inquired Mark.</p>
+
+<p>"The hotel's on fire!" shouted Jack.</p>
+
+<p>Mark sprang out of bed and with Jack rushed to the window, for their
+room was filled with thick smoke. They could see the dull glare of
+flames, which every moment were becoming brighter.</p>
+
+<p>The next instant a loud explosion shook the<span class='pagenum'><a name="Page_34" id="Page_34">[34]</a></span> building. It swayed and
+seemed likely to topple over. Outside the boys could hear excited shouts
+and the puffing and whistling of fire engines.</p>
+
+<p>"Quick! Run!" yelled Mark. He opened the door leading into the corridor,
+but was driven back by a rush of flames and smoke that almost stifled
+him.</p>
+
+<p>"We must try the fire escape!" shouted Mark.</p>
+
+<p>"Don't forget the valise with the tools;" exclaimed Jack, and Mark
+hastened to where he had placed it under the bed.</p>
+
+<p>Then the two boys rushed to the balcony on which their front windows
+opened, and whence the fire escapes led down to the streets. The lads
+had only time to slip on their coats, trousers, shoes and caps.</p>
+
+<p>As they were preparing to clamber down the iron ladders they heard
+someone on the balcony next to them shout:</p>
+
+<p>"Here, you boys! Stop! I want you!"<span class='pagenum'><a name="Page_35" id="Page_35">[35]</a></span></p>
+
+
+
+<hr style="width: 65%;" />
+<h2>CHAPTER V</h2>
+
+<h3>A GRAVE ACCUSATION</h3>
+
+
+<p>"We haven't time now!" yelled back Mark, looking in the direction of the
+voice, and seeing a short, stout man, who appeared greatly excited.</p>
+
+<p>"Stop or I'll shoot!" the man exclaimed.</p>
+
+<p>"The fire must have made him crazy," said Jack. "Go on, Mark, it's
+getting hot up above!"</p>
+
+<p>Mark did not linger on the ladder and soon the two boys were in the
+street, surrounded by an excited crowd.</p>
+
+<p>"Are you hurt?" asked several.</p>
+
+<p>"I guess not," replied Mark. "What caused the fire?"</p>
+
+<p>"Some sort of an explosion," answered a policeman. "Part of the hotel
+was blown up. If you boys wish you can go to a station house where
+you'll be comfortable until morning."</p>
+
+<p>"I guess we will," said Mark.</p>
+
+<p>They started to work their way through the crowd but did not notice that
+the strange man followed them. The fire was now burning fiercely,<span class='pagenum'><a name="Page_36" id="Page_36">[36]</a></span> and
+once they had gotten clear of the press the lads halted to look at the
+spectacle.</p>
+
+<p>The hotel was now a mass of flames and the firemen were kept busy. What
+with the puffing of engines, the whistling of the steamers, the roar of
+the flames, and the shouts of the crowd, pandemonium <ins title="Transcriber's Note: original reads 'reined'">reigned</ins>.</p>
+
+<p>The boys watched the fire for some time. Gradually the flames came under
+the control of the men and the leaping tongues died out.</p>
+
+<p>"I guess we'd better go to the police station," suggested Jack.</p>
+
+<p>Mark agreed this would be a good thing to do, as both of them felt
+rather chilly in the night air with only half of their clothes on. They
+inquired their way of the first policeman they saw, and he volunteered
+to escort them.</p>
+
+<p>"Sure an' you'll have plenty of company," he said. "The hotel was full
+an' the people have no place to go except to the lock-up. Some swells
+will be glad to take a place behind the bars to-night I'm thinkin'. I
+wonder how some of those English aristocrats will like it?"</p>
+
+<p>"English aristocrats?" repeated Jack. "Are any here?"</p>
+
+<p>"Sure. There's a lot of them burned out. Lord Peckham was stoppin' at
+the hotel with a big crowd of people, an' their apartments was all<span class='pagenum'><a name="Page_37" id="Page_37">[37]</a></span>
+destroyed. Some of 'em went to the police station."</p>
+
+<p>The boys followed their uniformed guide through the streets of Easton,
+and were soon at the station house. There they were received by the
+sergeant in charge, while the matron gave them each a cup of hot coffee,
+a large pot of the beverage having been brewed.</p>
+
+<p>"I'll have to give you boys one bed between you," said the sergeant.
+"We're rather crowded for room to-night."</p>
+
+<p>"Anything will do us," said Jack with a laugh.</p>
+
+<p>Just then there was some excitement at the entrance of the police
+station.</p>
+
+<p>"I tell you they're in here! I will see them!" a voice exclaimed. "I
+want them arrested at once!"</p>
+
+<p>"Go easy now," counseled the doorman as he tried to hold back a short,
+stout, excited man who was pushing his way into the station.</p>
+
+<p>"There they are!" exclaimed the man, pointing to Jack and Mark.</p>
+
+<p>"Why those boys are from the burned hotel," said the doorman.</p>
+
+<p>"I know it! They are the very ones I want!"</p>
+
+<p>"What do you of us?" spoke up Mark. He recognized the man as the one who
+had called to him as he and Jack were escaping.<span class='pagenum'><a name="Page_38" id="Page_38">[38]</a></span></p>
+
+<p>"I charge you with being sons of James Darrow, the notorious English
+anarchist!" cried the little man, pointing his finger at the boys, "and
+I accuse you of trying to kill Lord Peckham with a bomb, the explosion
+of which set fire to the hotel!"</p>
+
+<p>For a moment the surprising charge so astonished every one that not a
+word was said. Then the little man, advancing toward the boys went on:</p>
+
+<p>"I arrest you in the name of His Royal Highness, Edward VII, King of
+England, Scotland and Wales."</p>
+
+<p>He threw back the lapel of his coat and showed a badge.</p>
+
+<p>"King of England, Scotland and Wales, is it!" exclaimed the doorman with
+a twinkle in his eye. "An' why didn't ye say Ireland into the bargain."</p>
+
+<p>"Ireland, of course," went on the little man. "I'm an officer of His
+Most Gracious Majesty," he added, "and I demand the assistance of the
+United States authorities in general and the police of Easton in
+particular in taking these desperate criminals into custody!"</p>
+
+<p>"Hold your horses," advised the desk-sergeant. "Those boys are not
+liable to run away. They're to stay here over night, and if you have any
+charge<span class='pagenum'><a name="Page_39" id="Page_39">[39]</a></span> to make against them why you'll have to come and see the judge
+in the morning."</p>
+
+<p>"But they are sons of an anarchist! They are anarchists themselves!"
+exclaimed the man, "I must arrest them!"</p>
+
+<p>"You're not going to arrest anybody," said the sergeant, "until you get
+a warrant from the judge. This isn't England."</p>
+
+<p>"Then I'm going to stay with these boys the rest of the night," insisted
+the man. "I can't take any chances on their giving me the slip."</p>
+
+<p>"This place is going to be crowded with people from the burned hotel,"
+objected the sergeant. "There will be no room for you. Besides, how do I
+know these boys are anarchists?"</p>
+
+<p>"Look in their valise," cried the stranger. "It is filled with bombs."</p>
+
+<p>"You can't look in this satchel," exclaimed Jack, for he remembered the
+valise contained parts of the professor's secret machines.</p>
+
+<p>"What did I tell you?" cried the Englishman with triumph in his tones.
+"They are the guilty ones. They are afraid to open their valise."</p>
+
+<p>"We are, but not because it has bombs in it," said Mark. "It has parts
+of an unpatented machine and the owner does not want any one to see
+them," for Mark remembered Mr. Henderson's strict injunctions to let no
+one but the<span class='pagenum'><a name="Page_40" id="Page_40">[40]</a></span> mechanist to whom they had gone catch a glimpse of the
+parts that were to be duplicated. The machinist was sworn to secrecy.</p>
+
+<p>"It's none of our affair," said the sergeant, though he seemed a little
+impressed by the Englishman's words and the reluctance Mark and Jack
+showed to letting the valise be opened. "The boys will be here until
+morning, and then you can see the judge. Now you'll have to get out. You
+boys get to bed."</p>
+
+<p>Muttering threats, the stranger went from the station house, and Mark
+and Jack, in response to a nod from the doorman, followed him upstairs
+to a part of the police station used to detain witnesses. They were
+shown to a small room with a single bed.</p>
+
+<p>"Are ye really anarchists?" asked the doorman.</p>
+
+<p>"Not a bit," replied Jack, and he told as much of their story as he
+dared.</p>
+
+<p>"I was kind-of hopin' ye was," said the officer with a twinkle in his
+eye. "It wouldn't do any harm to scare that uppish Englishman a bit.
+Sure he an' his kind have done enough to poor old Ireland."</p>
+
+<p>"I'm sorry we can't oblige you," said Mark with a laugh.</p>
+
+<p>"I guess ye're all right," went on the door<span class='pagenum'><a name="Page_41" id="Page_41">[41]</a></span>man. "I hope ye sleep good
+the rest of the night."</p>
+
+<p>Then he left them alone. What with the excitement of the fire and the
+startling accusation against them, the boys' brains were too excited to
+let them sleep much. They had a few fitful naps throughout the remainder
+of the night.</p>
+
+<p>It was just getting daylight when Mark was awakened by some one shaking
+him.</p>
+
+<p>"What is it?" he asked. "Another fire?"</p>
+
+<p>"Not this time," replied a voice, and Mark, now that his eyes were fully
+opened, saw the doorman bending over him.</p>
+
+<p>"What's the matter?" asked Jack waking up in his turn.</p>
+
+<p>"Easy!" exclaimed the doorman in a whisper. "I happened to think ye
+might want to be leavin'."</p>
+
+<p>"Leaving?" asked Mark in bewilderment.</p>
+
+<p>"Yes. Ye know that Englishman is liable to be back any minute, an' he
+may make trouble for ye. I know ye're innocent lads, an' I'd hate to see
+ye mixed up in a mess with that fellow. So I slips up here early, an' ye
+can leave by the back door if ye want to, an' the officer of His
+Imperial Majesty, King Edward VII, will never know a thing about it."</p>
+
+<p>"It looks like running away," objected Jack.</p>
+
+<p>"Sure there's no charge agin ye," went on the<span class='pagenum'><a name="Page_42" id="Page_42">[42]</a></span> doorman. "Ye're free to
+come an' go as far as we're concerned, an' ye'd better go whilst ye have
+the chance."</p>
+
+<p>Jack reflected. It was true that the charge of the Englishman, baseless
+as it was, might make trouble for them, and cause them endless delays in
+getting back to Professor Henderson. Suddenly Jack made up his mind.</p>
+
+<p>"Come on Mark," he said.<span class='pagenum'><a name="Page_43" id="Page_43">[43]</a></span></p>
+
+
+
+<hr style="width: 65%;" />
+<h2>CHAPTER VI</h2>
+
+<h3>ON A RUNAWAY TROLLEY</h3>
+
+
+<p>"Are you going to leave?" asked Mark.</p>
+
+<p>"Certainly. There is no use staying here and getting mixed up in
+something that Englishman thinks we have done. It's easier to go away
+quietly and let him find out his mistake."</p>
+
+<p>"All right," agreed Mark. "I wonder who he is, anyhow?"</p>
+
+<p>"He thinks he owns the earth, whoever he is," returned Jack.</p>
+
+<p>"He's some sort of a special detective traveling with Lord Peckham's
+party," explained the doorman. "He told us a lot about himself last
+night after you boys went to bed. He came back to inquire how early the
+judge would be here.</p>
+
+<p>"He went on to tell how some English anarchists have vowed to kill Lord
+Peckham because he foreclosed a lot of mortgages on some poor people in
+Ireland where he owned property," added the doorman. "There was some
+sort of explosions in the hotel, near where Lord Peckham had his rooms.
+Maybe it was a bomb and,<span class='pagenum'><a name="Page_44" id="Page_44">[44]</a></span> maybe ag'in it was only the boiler. Anyhow,
+this detective jumped to the conclusion that anarchists had done it, and
+he thinks you are responsible. But you'd better be goin' now. It's
+gettin' daylight."</p>
+
+<p>So Mark and Jack, with what scanty clothes they had, and carrying their
+valise, went quietly out of the back door of the police station.</p>
+
+<p>"We'd better go to the machine shop for the rest of the stuff,"
+suggested Mark, "and then we can take the first trolley we see and get
+back to the professor."</p>
+
+<p>Through quiet side streets the boys made their way toward the machine
+shop. They were somewhat amused to think how they had fooled the
+detective, but they would not have felt so jolly had they seen the
+roughly dressed man who had darted after them as soon as they left the
+police station.</p>
+
+<p>"I'll get you yet," the man muttered. "You needn't think to escape with
+the aid of these bloomin' American police."</p>
+
+<p>The lads found the machinist just opening his shop though it was quite
+early. The pieces of apparatus were finished and, after paying for them
+Mark put the parts in the valise.</p>
+
+<p>"Quite a fire in town," observed the machinist.<span class='pagenum'><a name="Page_45" id="Page_45">[45]</a></span></p>
+
+<p>"Yes," answered Mark, not wishing to get into a long conversation.</p>
+
+<p>"Heard the hotel was blowed up by anarchists and that the police are
+after 'em," proceeded the man.</p>
+
+<p>"I believe I did hear something like that," admitted Mark. "I guess
+we'll be going."</p>
+
+<p>He signalled to Jack, and the two hurried out of the shop. As they did
+so, the trampish-looking man glided from behind a tree where he had been
+hiding and took after them.</p>
+
+<p>"Say," exclaimed Jack, "I forgot we haven't had any breakfast yet."</p>
+
+<p>"That's so," said Mark, rubbing his stomach and making a wry face.</p>
+
+<p>Near by was a bakery, and there the lads got some coffee and rolls which
+tasted fine. When they finished their simple meal a trolley came past
+and they ran to catch it. So did the man who had been following them,
+but this person bore no resemblance to the spruce little detective who
+had wanted to arrest the boys.</p>
+
+<p>"A couple of hours now and we'll be back at the cabin," spoke Mark. "My,
+but I must say we have had strenuous times since we started away!"</p>
+
+<p>There were few passengers on the trolley so early in the morning and not
+many stops to make,<span class='pagenum'><a name="Page_46" id="Page_46">[46]</a></span> so the motorman turned on the power full and made
+the vehicle speed along.</p>
+
+<p>Mile after mile was covered and finally the car reached the top of a
+long hill. At the foot of this the line came to an end, and the boys had
+a two mile tramp before them to reach the lonely spot where the
+<i>Porpoise</i> was docked.</p>
+
+<p>Down the hill the car started. The motorman shut off the electricity and
+let the vehicle run by its weight.</p>
+
+<p>Faster and faster it ran, the dust flying in a cloud about it.</p>
+
+<p>"Better put the brakes on a bit," called the conductor. "It's gettin'
+kinder speedy, Hank!"</p>
+
+<p>The motorman twisted the handle. There was a grinding noise as the shoes
+took hold on the wheels. Then a chain snapped and the car seemed to leap
+ahead.</p>
+
+<p>"The brake's busted! I can't stop the car!" yelled the motorman.</p>
+
+<p>Vainly he twisted at the handle. Then, seeing he could not stop the
+trolley car he made a desperate jump off the vehicle and landed in a
+heap on the side of the road, rolling over and over.</p>
+
+<p>"Reverse the current!" cried one of the passengers, to the conductor.
+"That ought to stop her!"<span class='pagenum'><a name="Page_47" id="Page_47">[47]</a></span></p>
+
+<p>The conductor made his way to the front platform and turned the
+reversing lever. Then he applied the current. But it was no use. With a
+blinding flash and a report like that of a gun a fuse blew out, and that
+crippled the car completely so far as the electric current was
+concerned.</p>
+
+<p>"Everybody jump!" cried the conductor. "There's a curve at the foot of
+the hill, and we'll all be killed if we stay on!"</p>
+
+<p>One by one the passengers leaped from the car. Several were badly hurt
+by the falls they got. Meanwhile the trolley was tearing down the hill
+at a terrific rate of speed.</p>
+
+<p>"Shall we jump?" asked Mark of Jack.</p>
+
+<p>"We'll be killed if we do," was Jack's answer.</p>
+
+<p>"And we'll be killed if we stay aboard," said Mark.</p>
+
+<p>"Not if I can help it," cried Jack as he started for the rear platform.</p>
+
+<p>"What are you going to do?" asked Mark.</p>
+
+<p>"Put on the other brake. They never thought to try this one! Maybe it
+will work and stop the car!"</p>
+
+<p>Then Mark saw what Jack was up to and went to help him. The shabbily
+dressed man seemed undecided what to do. He stood up, holding to the
+straps to prevent himself from being tossed from side to side as the
+runaway<span class='pagenum'><a name="Page_48" id="Page_48">[48]</a></span> trolley swayed. He watched the boys curiously.</p>
+
+<p>The lads, reaching the rear platform, twisted at the brake handle with
+all their strength. They could feel that the chain was still intact. But
+would the shoes grip the wheels with force sufficient to stop the car?</p>
+
+<p>There was a shrill screech as the brakes were applied by the boys. With
+all their might they turned the handle, winding the chain up tighter and
+tighter. At last they could not budge it another inch. Then they waited
+anxiously.</p>
+
+<p>The car never slackened its speed. So great was the momentum that had
+both sets of brakes been in working order it is doubtful whether they
+would have stopped the vehicle. The speed was so great now that one of
+the journals became hot and the oily waste that was packed in it caught
+fire, making what railroad men term a "hot box".</p>
+
+<p>"I guess we're done for," groaned Mark.</p>
+
+<p>"We certainly haven't checked the speed any," Jack admitted. "But wait a
+minute."</p>
+
+<p>He began stamping on the floor of the platform.</p>
+
+<p>"What you doing?" cried Mark, for he had to shout to make his voice
+heard above the roar and rattle of the car.</p>
+
+<p>"Putting on the sand," replied Jack, as he kicked at the plunger which,
+being depressed, let a stream of fine gravel out on the rails. "The<span class='pagenum'><a name="Page_49" id="Page_49">[49]</a></span>
+wheels are gripped I think, and are slipping on the rails. This may help
+some."</p>
+
+<p>"Let me give you a hand," exclaimed a voice, and the boys turned to see
+the shabby man standing with them on the platform. He grasped the brake
+handle, and gave it an additional turn. His strength seemed remarkable
+for so small a man.</p>
+
+<p>The speed of the car was checked a little, but the vehicle was still
+speeding along at a rate that would soon bring it to destruction if not
+halted before the curve was reached.</p>
+
+<p>"That's a little better," observed Mark. "It's a good thing you were
+here."</p>
+
+<p>"Good for me, not so good for you," said the man with a peculiar smile.</p>
+
+<p>"What do you mean?" asked Mark.</p>
+
+<p>"I mean that I shall have to place you under arrest for attempting to
+assassinate Lord Peckham!" exclaimed the man. "I am Detective Ducket, of
+Scotland Yard!"</p>
+
+<p>He stripped off a false beard he had donned, and threw back his coat,
+displaying his shield. He was the same man who had attempted to arrest
+the boys in the police station at Easton.</p>
+
+<p>"I've got you just where I want you now," Detective Ducket went on.
+"There are none of those blooming American police to interfere."</p>
+
+<p>The next instant the car gave a sudden lurch.<span class='pagenum'><a name="Page_50" id="Page_50">[50]</a></span> Then it seemed to rise up
+in the air. Jack felt himself flying through space, and he observed
+Mark, who was clinging to the valise, following him.</p>
+
+<p>There was a terrific crash, a ripping, tearing splintering sound, and
+the runaway trolley smashed into a big oak tree at the foot of the hill.
+The vehicle had completely jumped the track at the sharp curve.</p>
+
+<p>Jack's eyes grew dim, and he seemed to be sinking down in some dark pool
+of water. He heard a splashing beside him and began to strike out,
+trying to swim. He seemed to be choking. Then the blessed air and
+daylight came to him, and he found he was floating on the surface of a
+pond.</p>
+
+<p>He dashed the water from his eyes and saw, over on the bank, the wreck
+of the trolley. Then he noticed that Mark was swimming beside him.</p>
+
+<p>"What happened?" asked Jack.</p>
+
+<p>"A little of everything," panted Mark. "Lucky we weren't killed. We must
+have been flung off the rear platform into this duck pond."</p>
+
+<p>The boys soon made their way to shore, unhurt except for the wetting.
+The fall into the water had saved their lives.</p>
+
+<p>"Where's the valise of machinery?" asked Jack.<span class='pagenum'><a name="Page_51" id="Page_51">[51]</a></span></p>
+
+<p>"There it is," answered Mark pointing to where it had fallen at the back
+of the pond.</p>
+
+<p>"And what became of Detective Ducket?"</p>
+
+<p>"He's here, at your service!" exclaimed a voice. "Consider yourselves
+under arrest and don't you dare to leave this place without me."</p>
+
+<p>The boys looked in the direction of the sound and saw the English
+officer lying on the grass not far away. He seemed in pain, but had
+raised himself on his elbow and was pointing his finger sternly at the
+boys.<span class='pagenum'><a name="Page_52" id="Page_52">[52]</a></span></p>

+<h2>CHAPTER VII</h2>
+
+<h3>OFF FOR THE SOUTH POLE</h3>
+
+
+<p>"Are you hurt?" asked Jack.</p>
+
+<p>"I think my leg is broken, but otherwise I'm not damaged," replied the
+detective. "Even if I am disabled, it makes no difference, you are my
+prisoners. I command you to stay here until help comes."</p>
+
+<p>The boys did not know what to do. They did not like to see even an enemy
+suffer, but, at the same time, they knew he had no right to arrest them.</p>
+
+<p>"Here comes a wagon," said Mark, catching the sound of wheels.</p>
+
+<p>"Well, fo' de land sakes! Gollyation! What terrible catafterme hab
+occurred in dis unapproachable manner?" a voice demanded.</p>
+
+<p>"It's Washington!" cried Mark, as he saw Professor Henderson's colored
+assistant driving along the road.</p>
+
+<p>"Dat's who it am!" exclaimed Washington as he noticed the boys. "My! My!
+But am you boff dead?"<span class='pagenum'><a name="Page_53" id="Page_53">[53]</a></span></p>
+
+<p>"No, only one of us," said Mark with a laugh, as he and Jack ran toward
+the wagon.</p>
+
+<p>"Ha! Ha! Dat's one ob yo' jokes," said Washington. "But hurry up, boys.
+De perfessor he done sent me to meet you. He reckoned you'd becomin'
+ober on an early trolley. He's in a hurry to git away."</p>
+
+<p>"Don't you boys dare to leave!" exclaimed Detective Ducket.</p>
+
+<p>"Who's dat?" asked Washington.</p>
+
+<p>"Never mind," said Mark. "He was hurt in the trolley smash, but not
+badly. We'll send help, from the first farm house we come to. Come on,
+Washington, we'll go with you."</p>
+
+<p>The boys jumped into the wagon, and Washington started off. He explained
+that the inventor was anxious to make a start that day, as there would
+be an unusually high tide which would be followed a little later by a
+low one, and that would make it difficult to cross the harbor bar.</p>
+
+<p>"So I hired dis wagon an' come after you," said the colored man.</p>
+
+<p>At the first house they came to the boys stopped and told about the
+accident. The farmer agreed to go and get the detective and the others
+who were hurt and take them to a hospital.</p>
+
+<p>"I guess we're rid of that detective now," observed Jack, as they
+started off again.<span class='pagenum'><a name="Page_54" id="Page_54">[54]</a></span></p>
+
+<p>"Yes, but we're getting away under a cloud on our characters," said
+Mark. "I'd like to stay and see the thing through, if we had time."</p>
+
+<p>"But we can't, and there's no use worrying over it," spoke Jack.</p>
+
+<p>In a short time they were at the inventor's cabin, and related to Mr.
+Henderson all that had occurred.</p>
+
+<p>"Well I guess your detective friend will have a hard time to find you in
+a few hours," said the old man. "We start on our trip for the south pole
+this evening."</p>
+
+<p>There were busy times for the next few hours. Many supplies had to be
+placed on board, and, while the boys, with Tom and Bill, saw to this, the
+professor and Washington were occupied with putting the last touches to
+the submarine boat's machinery.</p>
+
+<p>Most of the supplies from the cabin were placed in the <i>Porpoise</i>,
+including food and clothing and a good quantity of minerals that, with
+sea water, generated the gas that made steam.</p>
+
+<p>An early supper was made on shore, as the professor said they might be
+so busy for the first few hours of the starting trip that they would get
+no chance to eat. Then the cabin and buildings where the submarine had
+been built, were securely fastened.<span class='pagenum'><a name="Page_55" id="Page_55">[55]</a></span></p>
+
+<p>"I guess we're all ready," announced the professor, taking a last look
+around.</p>
+
+<p>One by one they went aboard the <i>Porpoise</i> crawling down through the man
+hole. The inventor was the last one to enter. He clamped the cover on by
+means of the cam levers and switched on the electric lights. Then he
+took his place in the conning tower with Andy Sudds.</p>
+
+<p>"Forward, to the South Pole!" exclaimed Mr. Henderson.</p>
+
+<p>With a turn of his wrist the inventor started the engines. The big screw
+in the shaft revolved, pulling the water in at one end of the craft and
+sending it out in a swirling stream at the other. The trip was fairly
+begun.</p>
+
+<p>For several miles the <i>Porpoise</i> glided along on the surface of the
+ocean. It was a calm evening, and the boys down in the cabin of the
+craft could look into the reflecting mirrors on the wall, which were
+connected with observation magnifying glasses in the conning tower, and
+view what was going on, though their heads were below the surface of the
+sea.</p>
+
+<p>As it grew darker the view of shore and water faded away. The engine
+kept up its speed with Washington to see to it every now and then,
+oiling the bearings, some of which did not run quite smoothly because of
+their newness.<span class='pagenum'><a name="Page_56" id="Page_56">[56]</a></span></p>
+
+<p>"I'll send her down a bit now," observed the professor. "I don't want to
+run into any more warships or scare the crews by making them think we
+are a foreign torpedo boat."</p>
+
+<p>He opened the sea cocks in the ballast tanks and soon the <i>Porpoise</i>
+sunk about two hundred feet beneath the waves. The craft, which had been
+pitching and tossing under the influence of a ground swell, became more
+steady and quiet once it left the surface.</p>
+
+<p>The searchlight in the conning tower was turned on, and in the glare of
+it Andy and the professor were able to <ins title="Transcriber's Note: original reads 'stear'">steer</ins> properly, aided by the
+compass which gave them the true southern course.</p>
+
+<p>It was now quite dark. Additional electric lights were switched on in
+the cabin, engine and dining room. Andy came out of the conning tower
+and announced that Captain Henderson wanted Washington to get supper.</p>
+
+<p>All the cooking was done by electricity, and, in addition to a supply of
+the usual and ordinary kinds of food, there was a big lot of patent
+condensed victuals to draw on. Soup, broiled steak, potatoes, hot
+biscuits, rice pudding and coffee made up the repast which was enjoyed
+by all.</p>
+
+<p>Toward the close of the meal Professor Henderson began to sniff the air
+of the cabin.<span class='pagenum'><a name="Page_57" id="Page_57">[57]</a></span></p>
+
+<p>"What's the matter? Do you smell a storm brewing?" asked Andy.</p>
+
+<p>"No, but the air is not as fresh as it should be," replied the inventor.
+"Washington, release a little more of the supply from the compression
+tanks."</p>
+
+<p>The ship, which had been left to steer itself automatically while the
+professor was absent from the conning tower, was moving along at about
+half speed. The gage showed they were going at twenty miles an hour, and
+were three hundred feet below the surface.</p>
+
+<p>"Washington and I will share the first night's watch between us," said
+the inventor, after the supper things had been cleared away. "There will
+not be much to do, as the ship will <ins title="Transcriber's Note: original reads 'stear'">steer</ins> automatically in whatever
+direction I set her. Still I want to see how she behaves. The rest of
+you might as well go to your bunks."</p>
+
+<p>The two boys were especially glad of a chance to go to bed, as they had
+had but little sleep the night before on account of the fire. So they
+lost no time in undressing and rolling up in the blankets, for it was
+quite cool so far down under the water.</p>
+
+<p>"Well, we've slept on the earth, above the earth and now we're under the
+waters," observed Jack.<span class='pagenum'><a name="Page_58" id="Page_58">[58]</a></span></p>
+
+<p>"There's only one place more to spend your time taking a snooze," said
+Mark.</p>
+
+<p>"Where's that?"</p>
+
+<p>"Inside the earth."</p>
+
+<p>Then they fell asleep. During the night and the next day the <i>Porpoise</i>
+forged on underneath the waves. Washington relieved Mr. Henderson in the
+conning tower and reported the machinery to be working well.</p>
+
+<p>"Keep her headed due south," was the order of the inventor, and the
+colored man did so.</p>
+
+<p>It was about four o'clock one morning that Washington felt a slight jar
+to the submarine.</p>
+
+<p>"Hope we ain't goin' to hit no more battleships," he said.</p>
+
+<p>He glanced at the speed-indicating gage. To his surprise it stood at
+zero. The craft was not moving forward a foot! Yet the engines were
+going at half speed!</p>
+
+<p>In great alarm Washington shut off the power and ran to acquaint
+Professor Henderson with the news.</p>
+
+<p>"Suffin's ketched us!" cried the colored man.</p>
+
+<p>"Nonsense!" said the inventor, yet he seemed alarmed as he slipped on
+his clothes and hastened to the conning tower.</p>
+
+<p>He peered ahead along the path of water illuminated by the glare of the
+searchlight, but<span class='pagenum'><a name="Page_59" id="Page_59">[59]</a></span> nothing was to be seen. Then he started the engine,
+increasing the speed gradually until the big screw in the shaft revolved
+more than one thousand times a minute. Still the <i>Porpoise</i> never
+stirred. She remained in the same position, as if some giant hand
+grasped her.</p>
+
+<p>"Reverse the engine," said the professor.</p>
+
+<p>Washington did so. To the surprise of both of them the ship shot
+backward like a frightened crab.</p>
+
+<p>"Now forward!" exclaimed the old inventor.</p>
+
+<p>But this time the <i>Porpoise</i> did not move. It was as if she was up
+against a stone wall.</p>
+
+<p>"What's the matter?" asked Mark, who had been awakened by the excitement
+on board.</p>
+
+<p>"I do not know," replied Mr. Henderson gravely. "Something mysterious
+has occurred. We can go no further!"<span class='pagenum'><a name="Page_60" id="Page_60">[60]</a></span></p>
+
+
+
+<hr style="width: 65%;" />
+<h2>CHAPTER VIII</h2>
+
+<h3>ASHORE IN THE DARK</h3>
+
+
+<p>"Stop the engine," the captain commanded after he had peered through the
+lens in the conning tower for some time. "We must see what is the
+matter."</p>
+
+<p>He glanced at the depth gage and noted that they were now four hundred
+feet below the surface. Then he consulted some charts.</p>
+
+<p>"There is a depth of one thousand feet about here," he remarked. "Lower
+the ship, Washington. Let us see if by getting on the ocean bed we can
+get away from this obstruction."</p>
+
+<p>The colored man opened wider the sea cocks by which the tanks were
+filled. The increased ballast sunk the <i>Porpoise</i> still lower, and, in a
+few minutes a slight jar told the navigators that they were on the
+bottom of the ocean.</p>
+
+<p>"Now we will see if we have cleared the obstruction," said the
+professor.</p>
+
+<p>He started the big screw to revolving, but the ship did not move. It
+shivered and trembled throughout its length but remained stationary.<span class='pagenum'><a name="Page_61" id="Page_61">[61]</a></span></p>
+
+<p>"Maybe dar's a debil fish what hab circumulated dis ship in de exteror
+portion ob his anatomy," suggested Washington, rolling his eyes until
+only the whites were visible.</p>
+
+<p>"I presume you mean that a giant squid or cuttle fish has attacked us,"
+spoke the professor.</p>
+
+<p>"Yas, sir," replied Washington.</p>
+
+<p>"That's nonsense," went on the inventor. "However, we must make an
+investigation."</p>
+
+<p>"How are you going to do it?" asked Mark. "You can't see the end of the
+tube from inside the ship, and, even if we went to the surface it would
+still be under water."</p>
+
+<p>"We are going to look at it while here, under the ocean," said the
+inventor.</p>
+
+<p>"Well, maybe you're a good swimmer," put in Jack, "but I don't believe
+you can stay under, in this depth of water, long enough to see what the
+trouble is."</p>
+
+<p>"I think I can," answered Mr. Henderson.</p>
+
+<p>"How?"</p>
+
+<p>"I'll show you. Washington, bring out the diving suits."</p>
+
+<p>The colored man, his eyes growing bigger every minute, went to a locker
+and brought out what seemed quite a complicated bit of apparatus.</p>
+
+<p>"With the aid of these," said the professor, "I will be able to go out,
+walk along the ocean bed,<span class='pagenum'><a name="Page_62" id="Page_62">[62]</a></span> and investigate the mystery. Do you boys want
+to come along?"</p>
+
+<p>"Is it safe?" asked Mark, who was inclined to be cautious.</p>
+
+<p>"As safe as any part of this under-sea voyage," replied the professor.
+"These diving suits are something I have not told you about," he went
+on. "They are my own invention. Besides the regular rubber suits there
+is an interlining of steel,&mdash;something like the ancient suits of chain
+mail&mdash;to withstand the great pressure of water. Then, instead of being
+dependent on a supply of air, pumped into the helmet from an apparatus
+in a boat on the surface, each person carries his own air supply with
+him."</p>
+
+<p>"How is that?" asked Jack, and Mark also asked the question.</p>
+
+<p>"Simply by attaching a little tank of the compressed gas to the shoulder
+piece of the suit," said the inventor. "There is enough air in the tank
+to last for nearly a day. It is admitted to the helmet as needed by
+means of automatic valves. In other respects the diving suit is the same
+as the ordinary kind, except that there is a small searchlight, fed by a
+storage battery, on top of the helmet."</p>
+
+<p>In spite of their fears at venturing out under the great ocean, the two
+boys were anxious to<span class='pagenum'><a name="Page_63" id="Page_63">[63]</a></span> try the suits. So, after some hesitation, they
+donned them.</p>
+
+<p>"Here, take these with you," said the professor, before their <ins title="Transcriber's Note: original reads 'helmet'">helmets</ins>
+were screwed on. He held out what looked like long sticks.</p>
+
+<p>"What are they?" asked Jack.</p>
+
+<p>"Electric guns," replied the professor. "But come on now, we have no
+time to lose."</p>
+
+<p>Further conversation was impossible, for the boys had their heavy copper
+helmets on, and they were as tightly enclosed as if inside a box. They
+grasped their weapons and waited for the next move.</p>
+
+<p>The professor led the way to the stern of the ship. The boys found it
+hard to walk, as they were weighted down by the heavy suits, and also
+the boots, the soles of which were of lead.</p>
+
+<p>They followed the inventor into what seemed a small room. Inside they
+found themselves in darkness. There was a clanking sound as Washington
+fastened and clamped the door shut. Then came a hissing.</p>
+
+<p>The boys felt water rising about them. They could experience its
+coldness, even through the diving suits. They were much afraid, but the
+professor put a reassuring hand on their shoulders.</p>
+
+<p>They seemed to feel a great weight. It gradually lessened, however, and,
+in a few minutes, they<span class='pagenum'><a name="Page_64" id="Page_64">[64]</a></span> saw something move in front of them. The
+professor pushed them gently forward.</p>
+
+<p>In another instant they were walking on the bed of the ocean, having
+stepped from the <i>Porpoise</i>. They had gone into a locked compartment,
+the inner door of which had been tightly closed, after which water from
+outside had been gradually admitted until the pressure was equal, and
+then the boys and the professor had merely to emerge out into the bottom
+of the sea when the outer portal was swung aside by Washington, who
+worked the lever from inside.</p>
+
+<p>The boys were in intense darkness, but, suddenly a light glowed about
+them, and they saw that the professor had switched on his miniature
+search lamp. They remembered how he had told them to work the apparatus,
+and soon tiny gleams shot out from their helmets.</p>
+
+<p>The professor pointed ahead, for not a sound could be heard, and the
+boys followed him.</p>
+
+<p>It was a new sensation, this walking along the bed of the ocean. At
+first the great pressure of water, even though the steel lined diving
+suits kept most of it off, was unpleasant. Gradually, however, the boys
+became used to it. They had to move slowly, for the water was denser
+than the air and impeded their progress.</p>
+
+<p>In a few minutes they reached the forward<span class='pagenum'><a name="Page_65" id="Page_65">[65]</a></span> end of the <i>Porpoise</i>. Now
+they were to solve the mystery of what had stopped the submarine. For a
+few moments they could distinguish nothing.</p>
+
+<p>Suddenly the boys felt the professor grasping their arms. They looked in
+the direction he pointed. There in the diffused glare from the search
+light and the illumination of their helmet lamps they saw, wrapped about
+the forward shaft opening a gigantic squid or devil fish. Its soft,
+jelly-like body completely covered the opening of the shaft preventing
+any water from entering, and thus stopping any forward motion to the
+ship.</p>
+
+<p>This was what had caused all the trouble. The <i>Porpoise</i> had run into
+the monster, who feeling what it must have thought an enemy, had grasped
+the submarine with its long sinuous arms.</p>
+
+<p>The professor hesitated a moment. Then he slowly raised his electrical
+gun, and took aim at the hideous mass. The boys followed his example. At
+Mr. Henderson's signal they all fired together.</p>
+
+<p>From the muzzles of the guns darted small barbs that carried with them a
+strong shock of electricity, from storage batteries in the shoulder
+pieces of the weapons. Three of them were enough to produce death in an
+animal as large as a whale.<span class='pagenum'><a name="Page_66" id="Page_66">[66]</a></span></p>
+
+<p>The devil fish quivered. Then the water about it suddenly grew black,
+and the boys and the professor were in dense darkness, for the squid had
+dyed the ocean with a dark liquid from the sack it carried for the
+purpose.</p>
+
+<p>The explorers groped their way to the left, having fortunately grasped
+hands after firing their guns, to prevent being separated in case the
+terrible fish began a death struggle.</p>
+
+<p>Luckily Professor Henderson went in the right direction and managed to
+locate the <i>Porpoise</i>. Then, feeling along her steel sides, he led the
+boys through the inky blackness to the water chamber by which entrance
+could be had to the interior.</p>
+
+<p>In a few minutes all three were safely inside and had removed their
+diving suits. The others crowded about, anxious to learn what had
+happened. The inventor related it briefly.</p>
+
+<p>Once more the engines were started. This time there was no hanging back
+on the part of the <i>Porpoise</i>. The big screw revolved, the water came in
+the shaft and was thrust out of the rear end, making a current that sent
+the craft ahead swiftly. The gigantic fish had been killed, and its body
+no longer obstructed progress.</p>
+
+<p>"Now we'll rise to the surface and see how it feels to sail along that
+way for a while," said the professor as he started the pumps that
+emptied<span class='pagenum'><a name="Page_67" id="Page_67">[67]</a></span> the tanks. In a little while the ship was floating on the
+waves.</p>
+
+<p>It was now night, and the clouds overhead made it so dark that it was
+hard to see ten feet in advance. The professor did not want to use the
+searchlight for he did not care to have his presence discovered by
+curious persons. So he ran the ship at half speed.</p>
+
+<p>"Where are we now?" asked Mark, who had entered the conning tower, where
+the professor was <ins title="Transcriber's Note: original reads 'stearing'">steering</ins>.</p>
+
+<p>"Somewhere's off the coast of South Carolina," replied the inventor.</p>
+
+<p>The next instant there was a sudden shock and jar. The ship quivered
+from stem to stern, and came to an abrupt stop.</p>
+
+<p>"We've hit something!" exclaimed the professor, shutting down the
+engines with a jerk of the lever.<span class='pagenum'><a name="Page_68" id="Page_68">[68]</a></span></p>
+
+
+
+<hr style="width: 65%;" />
+<h2>CHAPTER IX</h2>
+
+<h3>A PRICE ON THEIR HEADS</h3>
+
+
+<p>On board the <i>Porpoise</i> there was great excitement. Washington, with
+Andy, Tom, Bill and Jack came running from the engine room.</p>
+
+<p>"What is it?" cried Jack.</p>
+
+<p>"I don't know," answered the professor as calmly as he could. "We'll
+soon see, however."</p>
+
+<p>He switched on the searchlight and peered from the conning tower.</p>
+
+<p>"Can you see anything?" asked Andy, anxiously.</p>
+
+<p>"I can," announced the inventor.</p>
+
+<p>"What?"</p>
+
+<p>"Land," replied Mr. Henderson. "We've hit the coast."</p>
+
+<p>"I hope we ain't done no damage," put in Washington.</p>
+
+<p>"Do you mean to the coast or to us?" asked the professor, with a smile.
+"I guess there isn't much danger in ramming the shore excepting to the
+<i>Porpoise</i>. However, we do not seem to be in any immediate trouble."<span class='pagenum'><a name="Page_69" id="Page_69">[69]</a></span></p>
+
+<p>He tested various wheels and levers, and announced that, aside from the
+jar, which might have started some of the machinery, the <i>Porpoise</i> was
+unharmed.</p>
+
+<p>The cover of the man-hole was loosened and, one after another, the
+adventurers crawled out on the small deck or platform. It took them a
+little while to become accustomed to the darkness, but soon they were
+able to make out that they had run on the muddy bank of the ocean beach.
+The tide was low and the <i>Porpoise</i> had rammed her nose well into the
+soft muck, which accounted for the lack of damage.</p>
+
+<p>"Well, I guess there is nothing to do excepting to wait for morning,"
+said Mr. Henderson. "It doesn't look like a very lively neighborhood
+about here. I don't believe we'll be disturbed."</p>
+
+<p>Save for the splash and lapping of the waves and the sound of the wind,
+it was as quiet as the proverbial graveyard. Not a light showed on
+shore, and the gleam from the search lamp of the <i>Porpoise</i> cut the
+darkness like a small moonbeam.</p>
+
+<p>"If there's nothing to do I'm going to turn in," said Andy. "I'm tired."</p>
+
+<p>The professor said this was a good suggestion, and, leaving instructions
+that Washington and Bill were to divide the night's watch between them,
+the inventor sought his bunk.<span class='pagenum'><a name="Page_70" id="Page_70">[70]</a></span></p>
+
+<p>The boys remained on deck a few minutes longer.</p>
+
+<p>"We certainly are getting our share of adventures," remarked Jack.</p>
+
+<p>"I should say so," answered Mark.</p>
+
+<p>"Gollyation yes!" exclaimed Washington. "You-uns done most been eat by
+dat air koslostrous specimen ob a parralleledon! I'm glad I didn't go.
+But I'se brave enough!"</p>
+
+<p>"What's that?" asked Mark suddenly, pointing to an object floating on
+the water.</p>
+
+<p>Washington turned to behold something white drifting along.</p>
+
+<p>"Oh my good land ob mercy! It's a ghost!" the colored man yelled. "It's
+a ghost! Land a' massy! Hide me some where, quick!"</p>
+
+<p>Washington fell on his knees and stretched up his clasped hands in
+supplication. The boys gazed curiously at the white object that was
+slowly floating toward the stranded ship.</p>
+
+<p>It rose and fell on the waves, with an odd motion.</p>
+
+<p>"I wonder what it is," said Mark.</p>
+
+<p>"We'll soon see," spoke Jack. "It's coming this way."</p>
+
+<p>"Don't go near it! Don't touch it, boys!" pleaded Washington. "It'll put
+de evil eye on yo', suah! Turn yo' haids away!"<span class='pagenum'><a name="Page_71" id="Page_71">[71]</a></span></p>
+
+<p>But the boys were not so easily frightened. The white thing did look
+queer, but Jack reasoned correctly that the darkness of the night
+magnified it, and made it appear stranger than it probably was.</p>
+
+<p>"I'm going to try to get it," said Mark.</p>
+
+<p>The white thing was now quite close. It resembled a bundle of rags,
+floating on top of the water, and, as it came nearer, it seemed to take
+on a curious form.</p>
+
+<p>"It's a baby! It's de ghost ob a little dead baby!" cried the colored
+man. "Let it alone, I tell you!"</p>
+
+<p>Indeed, now that Washington had suggested it, the boys could see a
+resemblance to a child in the white object. But this did not deter them.
+Jack secured a boat hook from where it was fastened to the platform.
+With it he gently poked at the white thing. The object seemed to
+collapse and Jack was conscious of a strange feeling. Then, with slow
+motions, he drew it close to the side of the ship.</p>
+
+<p>Lying on his face he was able to get a good look at the thing. He
+muttered an exclamation.</p>
+
+<p>"What is it?" cried Mark.</p>
+
+<p>"Nothing but a newspaper!" announced Jack with a laugh, as he threw it
+on the deck. "All our trouble for nothing."<span class='pagenum'><a name="Page_72" id="Page_72">[72]</a></span></p>
+
+<p>"I shore thought it were a ghost," cried Washington as he got up from
+his knees.</p>
+
+<p>The boys went to their bunks. They were the first ones awake the next
+morning, and Jack followed Mark on deck.</p>
+
+<p>"There's the paper you rescued from drowning," said Mark.</p>
+
+<p>"So it is," came from Jack. "I wonder if there's any news in it."</p>
+
+<p>The sheet had dried out and Jack spread it open. No sooner had he
+scanned the first page than he uttered a whistle.</p>
+
+<p>"Something startling?" asked Mark.</p>
+
+<p>"Startling! I guess yes! Look here!"</p>
+
+<p>Mark looked over Jack's shoulder. Staring at them, from amid a mass of
+other news was the announcement in big black type:</p>
+
+<div class='center'>
+<big>REWARD FOR BOY ANARCHISTS!</big><br />
+</div>
+
+<p>Then followed an account of the burning of the hotel at Easton, a vivid
+description with pictures, of how it had been blown up in an attempt to
+<ins title="Transcriber's Note: original reads 'assasinate'">assassinate</ins> Lord Peckham, and how the two boys, sons of an English
+anarchist, had escaped.</p>
+
+<p>The rest of the story was given over to a description which Jack and
+Mark could see was<span class='pagenum'><a name="Page_73" id="Page_73">[73]</a></span> meant for them though it was incorrect in several
+particulars. How the boys had escaped the detective, through the trolley
+car mishap, was related, and then came the startling announcement that
+the hotel authorities had offered a reward of $1,000 for the capture of
+either or both of the boy anarchists. To this Lord Peckham had added an
+equal sum.</p>
+
+<p>"Well, it looks as if we were of some importance in the world," remarked
+Jack.</p>
+
+<p>"Rather," agreed Mark. "Think of having a price on our heads! Well, that
+detective certainly is a hustler. When is that paper dated?"</p>
+
+<p>Jack looked and saw that the sheet had been issued in Charleston the day
+previous. It had probably been thrown overboard from some steamer, and
+had drifted toward shore.</p>
+
+<p>While the boys were speculating over the matter Professor Henderson came
+on deck. He saw something was up, and soon had the whole story from the
+boys.</p>
+
+<p>"I shouldn't worry about it," said the inventor. "They've got to catch
+you first, and it isn't like running away when you know you are guilty.
+You boys had no more to do with the fire than the man in the moon. And
+we'll soon be beyond the reach of rewards and newspapers."</p>
+
+<p>Nevertheless, the boys brooded over the mat<span class='pagenum'><a name="Page_74" id="Page_74">[74]</a></span>ter. It seemed that they
+were still under a cloud, and they wished very much that it could be
+cleared away.</p>
+
+<p>However there were soon busy times. The rising tide floated the boat,
+and soon it was riding safely at anchor. The professor needed some small
+bits of machinery, and had decided to send the boys to the nearest town
+for them. But the news in the paper changed his plans, and he sent Bill
+and Washington, who soon returned with the needed articles.</p>
+
+<p>"Now we'll make another start," said Mr. Henderson, as soon as all were
+on board once more. "This time I hope we will keep on until we reach the
+south pole!"</p>
+
+<p>He started the engine, the <i>Porpoise</i> sank beneath the waves, and with a
+hum of the big screw that throbbed and vibrated, was away again.<span class='pagenum'><a name="Page_75" id="Page_75">[75]</a></span></p>

+<h2>CHAPTER X</h2>
+
+<h3>ATTACKED BY A MONSTER</h3>
+
+
+<p>For several days the <i>Porpoise</i> plowed her way beneath the surface of
+the ocean. Obedient to the directing hand of Professor Henderson she
+rose or sank as the tanks were emptied or filled. He put the craft
+through several rather difficult movements to test her under all
+conditions. In each one she was a success.</p>
+
+<p>Dinner was sometimes eaten five hundred feet below the surface. Then
+while Washington washed the dishes and cleaned up the galley, Jack and
+Mark looked from the side windows at the strange life under water.</p>
+
+<p>They were getting farther south now and the water was warmer as the
+equator was approached. This produced a great variety of animal life,
+and the ocean fairly swarmed with fishes, big and little, strange and
+curious that could be seen from the glass bull's-eyes.</p>
+
+<p>Great sharks swam up alongside of the <i>Porpoise</i>, keeping pace with her
+in spite of her speed. Their cruel tigerish eyes and ugly mouths made<span class='pagenum'><a name="Page_76" id="Page_76">[76]</a></span>
+the boys shudder as they looked at the creatures. Then came odd
+creatures that seemed neither of the land or sea, but which swam along
+with their horrible bodies flapping up against the glass. One and all,
+the inhabitants of the ocean seemed to resent the intrusion of the
+submarine.</p>
+
+<p>One day the boys turned the light out in the cabin and sat in the
+darkness the better to observe the fishes. The sea, in the vicinity of
+the ship, was illuminated with a sort of glow that diffused from the
+searchlight.</p>
+
+<p>Suddenly, as the boys were watching, there came a thud on the glass
+window at the port side. They glanced in that direction to see some
+horrible thing peering in at them through the window.</p>
+
+<p>At first they were greatly frightened. Two big eyes of green, with rims
+of what looked like red fire, stared at them, and, there was an ugly
+mouth lined with three rows of teeth.</p>
+
+<p>"It's only a fish," said Mark.</p>
+
+<p>"Well, I wouldn't like to meet it outside," said Jack. "I'd rather be
+here. My, but it's a nasty sight!"</p>
+
+<p>"Let's give Washington a little scare," suggested Mark.</p>
+
+<p>"How?"</p>
+
+<p>"We'll go out and tell him some one in the cabin <ins title="Transcriber's Note: original reads 'want's'">wants</ins> to see him. The
+fish will stay there.<span class='pagenum'><a name="Page_77" id="Page_77">[77]</a></span> See, it is fastened to the glass by some sort of
+suction arrangement, like the octupus fish have on their arms. Then
+we'll look in and see what Wash does."</p>
+
+<p>Jack agreed to the plan. The boys left the cabin, and Mark called to the
+colored man, who was in the engine room.</p>
+
+<p>"I'll go right instanter this minute," said Washington. "Don't no grass
+grow under dis chile's feet!"</p>
+
+<p>"Now listen," said Mark as he and Jack tiptoed after the colored man.</p>
+
+<p>Washington had no sooner entered the darkened cabin, and caught sight of
+the horrible staring red and green eyes looking straight at him, than he
+let out a yell that could be heard all over the ship. Then the colored
+man dropped on his knees and began to implore:</p>
+
+<p>"Good please Mr. Satan fish, doan take Washington White," he begged.
+"It's all a mistake. I didn't do nuffin. Good please Mr. Satan fish,
+take some one else. It's disproportionate to de circumulation ob de
+interiorness ob dis subicecream ship, so kindly pass me by dis time!"</p>
+
+<p>"What's the matter?" asked Amos Henderson, as he came hurrying into the
+cabin, seeking the cause for Washington's loud cry.</p>
+
+<p>Jack and Mark, who came in at that juncture,<span class='pagenum'><a name="Page_78" id="Page_78">[78]</a></span> were a little bit ashamed
+of the trick they had played.</p>
+
+<p>"What is the trouble?" repeated Mr. Henderson.</p>
+
+<p>"We's all goin' to be devoured alibe!" cried Washington pointing to the
+fish, that still clung to the glass.</p>
+
+<p>"Ah, a sucker fish!" remarked the inventor. "A large specimen, too.
+Don't be afraid Washington, it can't hurt you."</p>
+
+<p>"He looks like he could," said the colored man. "Look at dem teef!"</p>
+
+<p>Indeed the creature's mouth was a horrible sight, as it opened and shut.</p>
+
+<p>"I'll show you how to get rid of him," said the professor.</p>
+
+<p>He turned on the electric lights in the cabin, flooding the room with a
+bright glow. The big fish darted off, and, when the lights were turned
+out again, the terrible eyes did not reappear, much to their
+satisfaction.</p>
+
+<p>"The lights scared it away," remarked the inventor. "But you mustn't get
+frightened so easily, Washington. You'll see stranger sights than that
+before you're through with this voyage."</p>
+
+<p>"Oh I wasn't 'fraid," spoke up Washington. "I were jest 'stonished,
+dat's all."<span class='pagenum'><a name="Page_79" id="Page_79">[79]</a></span></p>
+
+<p>"What did you get down on your knees for?" asked Mark with a grin.</p>
+
+<p>"I might hab been lookin' for my collar button, for all you knows,"
+replied Washington, with an air of great dignity, and went back to the
+engine room.</p>
+
+<p>For several days after this the <i>Porpoise</i> continued on her way south.
+Now and then appearing on the surface to renew the supply of fresh air,
+and again skimming along under the surface, or deep down, the strange
+craft kept on. It grew much warmer, and even when some distance below
+the surface the heat could be felt in an uncomfortable manner.</p>
+
+<p>"We're getting near the equator," explained the professor.</p>
+
+<p>One afternoon, when dinner had just been finished, and the ship, under
+the direction of Washington, was gliding along well under the sea, there
+came a sudden shock.</p>
+
+<p>"We've hit something!" exclaimed Mr. Henderson as he jumped for the
+conning tower. The shock was repeated.</p>
+
+<p>"What was it?" asked someone.</p>
+
+<p>"Shut down the engine!" yelled the inventor to the colored man. "What do
+you want to go on ramming an object after you've once hit it? Slow down
+the engine!"<span class='pagenum'><a name="Page_80" id="Page_80">[80]</a></span></p>
+
+<p>"Power's shut off!" cried Washington. "We didn't hit nothin'! Something
+hit us!"</p>
+
+<p>"What do you mean?" asked Mr. Henderson.</p>
+
+<p>"Somethin's rammin' us," went on Washington.</p>
+
+<p>"It must be a big monster. I was sterrin' along an' there was nothin' in
+de road, when all of a suddint, ker-plunk! We's hit. Look ahead, an' you
+can't see nothin'!"</p>
+
+<p>The professor, and the boys, who had followed him, gazed out of the
+conning tower window. There was nothing forward but a vast expanse of
+water.</p>
+
+<p>The next instant the ship careened as something struck her a violent
+blow on the port side. Everyone almost toppled over from the force of
+the impact.</p>
+
+<p>"Dar he goes agin!" cried Washington.</p>
+
+<p>"We're attacked by a whale!" said the professor. "We must rise to the
+surface or it may damage the ship."</p>
+
+<p>"If it's a whale I'd like to get a shot at it," put in Andy Sudds, from
+the foot of the companion ladder leading into the tower.</p>
+
+<p>"I don't know that it is a whale," went on the inventor. "But it must be
+something very big and strong."</p>
+
+<p>"It's a monster of some sort," put in Andy, "and I want a chance at
+him."<span class='pagenum'><a name="Page_81" id="Page_81">[81]</a></span></p>
+
+<p>"It's too risky," murmured the professor. "We couldn't get down to
+bottom here, as the water is several miles deep, and the pressure would
+crush the <i>Porpoise</i>, strong as she is."</p>
+
+<p>Once more came a terrible blow and the ship rocked in a swirl of foam
+beneath the waves. In quick succession two more fierce onslaughts were
+made by the unseen monster.</p>
+
+<p>"We'll have to do something," muttered Andy.</p>
+
+<p>"You're right," agreed the professor. "Our only chance is to rise to the
+surface, for I do not believe the creature will follow us there. Empty
+the tanks, Washington."</p>
+
+<p>The colored man started the pumps, and the professor watched the gages
+that told the depth of the craft. The pointer should have begun to swing
+around in a few seconds after the tanks began to empty. Instead it
+remained stationary.</p>
+
+<p>"Strange," said Mr. Henderson. "I wonder if anything is wrong with the
+machinery."</p>
+
+<p>"More like the whale, or whatever it is, is on top of the boat, holding
+her down," suggested Andy.</p>
+
+<p>There was no doubt of this a moment later, for there were several
+violent blows on the upper part of the <i>Porpoise</i>.</p>
+
+<p>The crew of the submarine were held prisoners below the surface by the
+unknown monster!<span class='pagenum'><a name="Page_82" id="Page_82">[82]</a></span></p>
+
+<p>For a few minutes the thought of the awful fate that would be theirs if
+the ship should be wrecked under the water made each one speechless. As
+they stood looking at each other, not knowing what to do, the attack was
+renewed on the port side.</p>
+
+<p>The big fish, whale or whatever it was, kept pounding away.</p>
+
+<p>"I have an idea!" cried Andy suddenly.</p>
+
+<p>"What is it?" asked the professor quickly.</p>
+
+<p>"Let me put a diving dress on," began the old hunter.</p>
+
+<p>"I tell you we can't sink to the bottom in this depth of water,"
+interrupted the professor.</p>
+
+<p>"We don't need to," put in Andy. "All I want is a diving suit and a
+chance to stand out in the diving chamber. I guess I can fix Mr. Whale,
+if I have one of those electric guns."</p>
+
+<p>"Quick! Get a diving suit, Washington!" cried Mr. Henderson. He saw what
+the old hunter planned to do.</p>
+
+<p>In a few minutes Andy was dressed in the suit. The attacks of the
+monster had redoubled in frequency, and the ship rocked as in a storm.</p>
+
+<p>Andy stepped into the diving chamber, clasping the electric gun. The
+<ins title="Transcriber's Note: original reads 'innner'">inner</ins> door was tightly closed and then the sea cocks that admitted water
+from the outside were opened. When the pressure inside the chamber was
+equal to that of the ocean<span class='pagenum'><a name="Page_83" id="Page_83">[83]</a></span> outside some one pulled the lever that
+opened the outer door.</p>
+
+<p>Andy knew better than to step outside. He remained in the chamber, like
+a sentinel hid in the embrasure of a wall, for the chamber was a sort of
+big dent in the side of the <i>Porpoise</i>.</p>
+
+<p>Once more the ship rocked from a terrific blow, and the old hunter was
+nearly thrown out and into the fathomless depths below.</p>
+
+<p>He clung to the door lever and peered out. Through the big glass eyes of
+his copper helmet he saw headed straight at him a whale that seemed
+larger than the submarine.<span class='pagenum'><a name="Page_84" id="Page_84">[84]</a></span></p>
+
+
+
+<hr style="width: 65%;" />
+<h2>CHAPTER XI</h2>
+
+<h3>CAUGHT IN A SEA OF GRASS</h3>
+
+
+<p>"It's all up with me and the ship, too," thought Andy as he stood in the
+small chamber and watched the oncoming of the monster.</p>
+
+<p>However, he was not going to die without a fight, so he raised the
+electric gun. Yet he knew it was a most forlorn chance.</p>
+
+<p>He aimed straight down the big open mouth and pulled the trigger. The
+next instant the water all about him was a mass of foam, through which
+he could dimly see that the whale had halted.</p>
+
+<p>And, as the old hunter watched, in awe and fear at what he saw, he noted
+that instead of one monster there seemed to be a pair. Together they
+were threshing the sea into a bloody foam.</p>
+
+<p>Then, turning on the searchlight in his helmet, Andy beheld a terrible
+sight. The whale had been attacked by a gigantic swordfish at the moment
+the hunter had fired the shot, and it was that, and not the electric
+bullet, that had stopped the infuriated animal's rush at the ship.</p>
+
+<p>Ancient enemies, the whale and swordfish, had<span class='pagenum'><a name="Page_85" id="Page_85">[85]</a></span> met in mortal combat. The
+swordfish had engaged the whale just as it was about to strike what
+would probably have been a blow that would have disabled the submarine,
+for with the door of the diving chamber open, the onslaught might not
+have been withstood.</p>
+
+<p>Rushing here and there, the whale seeking to destroy his enemy with a
+sweep of the enormous flukes, and the swordfish plunging his bony weapon
+again and again into the whale, the two monsters fought until the water
+about the ship was a mass of foam and blood.</p>
+
+<p>Much as he wanted to see the end of the fight, Andy knew it was
+dangerous to remain longer with the door open.</p>
+
+<p>He closed it, pressed the lever which started the <ins title="Transcriber's Note: original reads 'pumped'">pumps</ins>, forcing the
+water from the chamber and, in a few minutes, emerged into the interior
+of the ship.</p>
+
+<p>Mr. Henderson, realizing that something out of the ordinary was going
+on, had opened the slides of the bull's-eye windows, and those in the
+submarine saw part of the fight between the whale and swordfish.</p>
+
+<p>As soon as Andy had removed his diving suit he advised that the ship be
+sent to the surface, as there might be danger should the monsters get
+too close in their struggles.<span class='pagenum'><a name="Page_86" id="Page_86">[86]</a></span></p>
+
+<p>Accordingly the pumps, which had been stopped when it was found
+impossible to raise the ship, because of the weight of the whale, were
+started and the <i>Porpoise</i> was soon on the surface.</p>
+
+<p>The manhole cover was opened and Andy, with Jack and Mark, went out on
+deck. They had no sooner stepped out on the platform than there was a
+commotion in the water.</p>
+
+<p>"They're going to fight up here!" exclaimed Mark.</p>
+
+<p>A big body shot upward and fell back with a splash, rocking the
+submarine.</p>
+
+<p>"There's the whale," observed Andy. "But I reckon he won't fight any
+more. He's dead."</p>
+
+<p>It was so. The swordfish had conquered, and the lifeless body of the
+whale floated on top of the water, only to sink a little later.</p>
+
+<p>"It was a great battle," said Jack. "I'm glad I was inside the ship."</p>
+
+<p>The course was due south, and every minute it seemed to the boys that it
+was getting warmer, for they were approaching the equator. Every hour
+brought them nearer the south pole, though they were still several
+thousand miles from it.</p>
+
+<p>After a while quite a wind sprang up, and as the sea roughened the
+professor decided to go down under the surface. The <i>Porpoise</i> sunk as
+the tanks filled and, in a little while, the submarine was in<span class='pagenum'><a name="Page_87" id="Page_87">[87]</a></span> calm
+water, and was forging ahead at three-quarter speed.</p>
+
+<p>It was three days after the adventure with the whale when, as the ship
+was going along at a good rate, that there seemed to be a gradual
+slacking in the progress.</p>
+
+<p>"I wonder what Washington is slowing down for," said the professor
+rising from the dinner table at which all save the colored man had been
+sitting. "I told him to keep right on. He must have seen something
+ahead. I'll take a look."</p>
+
+<p>The inventor went to the conning tower, where Washington was <ins title="Transcriber's Note: original reads 'stearing'">steering</ins>.</p>
+
+<p>"What are you stopping for?" he asked.</p>
+
+<p>"I'm not slowin' down," replied the colored man. "Guess another ob dem
+debil fishes has grabbed holt ob de ship. Dey suttinly am de most
+koslostrous conglomerations ob inconsequence dat I eber see."</p>
+
+<p>"You must keep your big words for another time," remarked Mr. Henderson,
+who seemed worried. "Hurry to the engine-room and see if the machinery
+is all right. We certainly are slowing down, from some cause or other."</p>
+
+<p>The <i>Porpoise</i> was now scarcely moving, though from the vibration it was
+evident that the engines were working almost at top speed. Washington
+came back and reported that the big screw was re<span class='pagenum'><a name="Page_88" id="Page_88">[88]</a></span>volving properly and
+that all the machinery was working well.</p>
+
+<p>"Then we're caught in something," said the professor. "Shut off the
+power, Washington, I don't want to strain things."</p>
+
+<p>The ship was now scarcely making a foot a minute, and, a little later,
+when the colored man had turned off the engine, the submarine became
+stationary, merely undulating with the roll and heave of the ocean.</p>
+
+<p>Hurrying to the cabin, Captain Henderson opened the side window
+shutters, turned off the electric lights and peered out.</p>
+
+<p>"I can't see anything," he said. "Yet I should be able to, as we are not
+very deep."</p>
+
+<p>The gage showed that the ship was submerged only thirty feet, and at
+that depth there should have been no difficulty in seeing, at least
+dimly, objects under water. But the windows showed as black as night.</p>
+
+<p>"Bring me one of the portable searchlights," called Mr. Henderson.</p>
+
+<p>Washington brought one, operated by a storage battery. Holding it so the
+reflector cast the beams out of the bull's-eye and into the water on the
+opposite side, the inventor peered forth.</p>
+
+<p>"I was afraid of this!" he murmured.</p>
+
+<p>"What is it?" asked Jack.<span class='pagenum'><a name="Page_89" id="Page_89">[89]</a></span></p>
+
+<p>"We are caught in the Sargasso Sea," replied Mr. Henderson.</p>
+
+<p>"The Sargasso Sea?" repeated Mark, in a questioning tone. "What is
+that?"</p>
+
+<p>"It is a great sea of grass," replied the captain. "An immense ocean of
+sea weed, that sometimes floats on the surface and sometimes a little
+below. The stalks or blades of the grass are very long and closely
+matted together."</p>
+
+<p>"Is there any danger?" asked Andy in some alarm.</p>
+
+<p>"Very much," answered the professor quietly. "A ship, once fairly
+entangled in the grass or sea weed, seldom gets out. If it is a sailing
+ship the weed clings to the rudder, making steerage impossible, and even
+in a strong wind the ship cannot get free of the mass. The grass winds
+about the <ins title="Transcriber's Note: original reads 'propellors'">propellers</ins> of steamships, and holds them as tight as in a
+vise.</p>
+
+<p>"Sometimes a great storm may tear the mass of weed loose from the bottom
+of the ocean, and then the ship is free. But the Sargasso Sea is the
+graveyard of many a fine vessel."</p>
+
+<p>The pumps were set going. Anxiously everyone watched the gage. The
+pointer never moved, but remained at thirty feet. The <i>Porpoise</i> was
+caught.</p>
+
+<p>"Well, since we can't go up, let us see if we<span class='pagenum'><a name="Page_90" id="Page_90">[90]</a></span> can go down," said the
+inventor. "Perhaps we can dive under the sea weed."</p>
+
+<p>The cocks of the tanks were opened and the water rushed in. Under the
+weight of it the ship should have sunk to the bottom. Instead it
+remained just where it was, thirty feet below the surface.</p>
+
+<p>"Try the screw again," suggested Andy, "Maybe we can back out."</p>
+
+<p>The big <ins title="Transcriber's Note: original reads 'propellor'">propeller</ins> in the tube was started going in a reverse direction,
+but the <i>Porpoise</i> only moved a few feet and then stopped. To go forward
+was equally impossible.</p>
+
+<p>The submarine was held fast in the grip of the long, sinuous, snake-like
+fingers of the terrible sea grass. Weak as one strand was, the thousands
+combined served to fasten the ship as securely as wire cables would have
+done. The weeds had entangled themselves all around the craft and
+refused to let go.</p>
+
+<p>"Well," remarked Mr. Henderson when all efforts had failed. "We must
+think of a new plan."</p>
+
+<p>He spoke cheerfully, for he did not want the boys and other members of
+the crew to know how worried he was. This was a danger he had never
+counted on when he planned to go to the south pole.<span class='pagenum'><a name="Page_91" id="Page_91">[91]</a></span></p>
+
+<p>"There is no great hurry," Mr. Henderson went on in a few minutes. "We
+can stay here for several days if need be, and by that time a storm may
+tear the grass loose."</p>
+
+<p>"If we had our old hay sythes here," spoke Bill, "me an' Tom could put
+on divin' suits an' go out an' cut the sea weed."</p>
+
+<p>"I'm afraid that wouldn't work," answered Mr. Henderson. "I'll think up
+some plan, soon."</p>
+
+<p>He started toward the engine room to look over the machinery. He was met
+by Washington, who seemed much alarmed.</p>
+
+<p>"What's the matter?" asked the inventor.</p>
+
+<p>"De air tank hab busted an' all de air is escapin' out!" cried the
+colored man. "We'll all smothercate!"<span class='pagenum'><a name="Page_92" id="Page_92">[92]</a></span></p>

+<h2>CHAPTER XII</h2>
+
+<h3>FIRE ON BOARD</h3>
+
+
+<p>The professor jumped past Washington and hurried into the room where the
+tanks were kept, carrying the reserve supply of air for breathing when
+the ship was under water. A loud hissing told that the leak was a large
+one.</p>
+
+<p>"Quick! Bring me some tools and a steel plug," shouted the captain.</p>
+
+<p>Mark hurried in with the things the professor wanted. But before the
+plug could be put in the hole the air stopped hissing.</p>
+
+<p>"The leak is fixed!" cried Jack.</p>
+
+<p>"No," said the professor in a strange voice.</p>
+
+<p>"But the air no longer rushes out."</p>
+
+<p>"For a good reason, there is no longer any air to rush out. It is all
+gone!"</p>
+
+<p>"Do you mean to say that all the reserve stock has been lost?" exclaimed
+Andy.</p>
+
+<p>"I fear so. The leak must have been a bad one. The air was stored in
+tanks under pressure, and, as you know, we released it as we needed it.
+Now it is all gone."<span class='pagenum'><a name="Page_93" id="Page_93">[93]</a></span></p>
+
+<p>"All? Then we shall smother," said Jack, and his voice trembled.</p>
+
+<p>"Not at once," went on Mr. Henderson in a calm voice. "There is enough
+air in the entire ship, including that which has leaked from the tanks
+to last us five hours. After that&mdash;&mdash;" he paused and looked at his
+watch.</p>
+
+<p>"Well?" asked Andy. "After that?"</p>
+
+<p>"There is enough stored in the small tanks of the diving suits to last
+another two hours, perhaps. Seven hours in all."</p>
+
+<p>"Then what?" asked Mark.</p>
+
+<p>"We shall smother to death," said the professor in a low tone. "That
+is," he went on, "unless before that time we can raise the <i>Porpoise</i> to
+the surface of the sea and get a fresh supply of air."</p>
+
+<p>"Then we must work to raise the ship," put in Bill. "Let' get out and
+see if we can't cut through the sea weed."</p>
+
+<p>"It would be useless," said Mr. Henderson. "We can only depend on the
+power of the ship herself. But do not be discouraged. We may escape.
+Come, Washington, start the engine again. By keeping it going constantly
+we can, perhaps, break loose from the grass. It is our only hope."</p>
+
+<p>Steadily the machinery worked. It might as<span class='pagenum'><a name="Page_94" id="Page_94">[94]</a></span> well have remained
+stationary, however, as far as any noticeable effect was made on the
+boat's progress. The grass of the Sargasso Sea held the <i>Porpoise</i> in a
+firm grasp.</p>
+
+<p>Four hours passed. There was nothing to do but wait and see what would
+happen. It all depended on the engines. Silently the navigators of the
+realms under the ocean sat and hoped. Now and then the professor would
+go to the engine room to adjust the machines.</p>
+
+<p>The atmosphere in the cabin was growing noticeably heavier. The boys'
+heads began to ring with strange noises, and there was a tightness
+across their chests. The lack of fresh air was beginning to tell.</p>
+
+<p>"We might as well use that in the diving suit reservoirs," remarked the
+professor. "We will feel better, at least for a little while."</p>
+
+<p>The helmets of the suits were brought in, and the vapor released from
+the small tanks. A change was at once noticed. The old stale air in the
+cabin was forced out of the exhaust pipes, and the fresh took its place.
+Every one felt better.</p>
+
+<p>Faster and faster revolved the big screw. The ship vibrated more and
+more. Yet it did not move, nor did it rise. The crew were still
+prisoners beneath the water.<span class='pagenum'><a name="Page_95" id="Page_95">[95]</a></span></p>
+
+<p>For an hour or so conditions were fairly comfortable. Then the same
+unpleasantness was experienced as was noticed before.</p>
+
+<p>"If we could only open a window," sighed Mark, "and let in a lot of
+fresh air, how nice it would be."</p>
+
+<p>The air rapidly became more foul. Soon Washington was gasping for
+breath. Tom and Bill showed signs of uneasiness.</p>
+
+<p>"Lie down on the floor," counseled the professor. "You will find the air
+a little fresher down there."</p>
+
+<p>They all did as he advised, the inventor himself stretching out at full
+length. A little relief was experienced.</p>
+
+<p>They knew it could not last long. Even the professor seemed to have
+given up hope. The engine was not going to free the ship in time to save
+the lives of those on board.</p>
+
+<p>Washington crawled to the engine room, as some of the bearings needed
+oiling. The professor seemed in despair. He opened one of the slides
+that covered the glass bulls eye windows. Then he turned off the
+electric lights. The opening was black, showing that the sea of grass
+still surrounded them. With a groan Mr. Henderson turned aside. The last
+hope was gone. He sank down on the floor of the darkened cabin.<span class='pagenum'><a name="Page_96" id="Page_96">[96]</a></span></p>
+
+<p>Just then Mark happened to look at the bull's-eye. He saw a glimmer of
+light. Then he noticed several fishes swimming about. The water was
+clear. The grass had disappeared from the vicinity of the window.</p>
+
+<p>"Look!" cried Mark to the professor.</p>
+
+<p>The inventor peered forth. As he did so he uttered a cry. Then he
+staggered rather than ran to the engine room.</p>
+
+<p>"What are you doing?" he called to Washington.</p>
+
+<p>"I jest let some ob de sulphuric acid out ob de storage battery tank,"
+replied the colored man.</p>
+
+<p>"That's it! That's it!" exclaimed the professor. "Quick, let some more
+out, Washington. Let out all there is in that tank. It will save our
+lives."</p>
+
+<p>Wonderingly Washington obeyed. The air in the ship was growing more foul
+every second. It was hard to breathe even on the floor, and all were
+gasping for breath. A few minutes more and they would all become
+unconscious and death would come in a little while if the air was not
+freshened.</p>
+
+<p>The professor staggered back to the main cabin. He looked out of the
+bull's-eye windows. Then he exclaimed:</p>
+
+<p>"See, it is getting lighter! Thank Heaven we are saved!"<span class='pagenum'><a name="Page_97" id="Page_97">[97]</a></span></p>
+
+<p>The next instant the ship began to move backward. Then with increasing
+speed it pulled out of the grip of the long grass, and in another minute
+was floating on top of the water, at the edge of the Sargasso Sea.</p>
+
+<p>"Quick! Open the man hole cover!" said Amos Henderson.</p>
+
+<p>Washington threw back the lever cams, and in rushed the fresh air. It
+was a blessed relief from the terrible oppressiveness of the foul
+atmosphere of the boat. They all breathed deeply, and, in a few minutes
+the effects of their long imprisonment had passed off.</p>
+
+<p>They went out on the small deck. It was getting dusk, and the reflection
+of the red sunset shone brightly on the heaving water.</p>
+
+<p>"I 'spected I'd neber see dis again," said Washington. "Thought suah I
+was a gone chicken!"</p>
+
+<p>"We had a most fortunate escape," said the professor. "You did the trick
+for us when you let the acid run from that tank into the sea. It mingled
+with the water and burned or ate through the stems of the grass so they
+no longer held the ship. I saw what had happened as soon as I looked out
+of the bull's-eye, and that's why I had you turn out all the acid you
+could. It was just as if liquid fire had touched the sea weed and burnt
+it off."<span class='pagenum'><a name="Page_98" id="Page_98">[98]</a></span></p>
+
+<p>"Golly!" exclaimed Washington. "Fust I know I'll be a perfessor myself!"</p>
+
+<p>Supper was eaten with the ship on the surface of the ocean, for it was
+impossible to go below until the leak in the air tanks had been
+repaired. Work was begun on this the next day, and though it proved a
+difficult job it was accomplished by Mr. Henderson and the boys.</p>
+
+<p>There were several minor repairs to be made to the machinery, and it was
+a week before all was in readiness for another descent beneath the
+waves. In the meanwhile the craft had moved slowly southward on the
+surface, where no very great speed was possible.</p>
+
+<p>Toward evening, on the seventh day after their adventure with the
+Sargasso Sea, the travelers closed the man hole, and with air tanks well
+filled slowly sank beneath the waves. Supper was eaten at a depth of
+sixty feet, and after the meal, while Washington was washing the dishes,
+the others sat and looked out through the bull's-eyes at the big fishes
+which floated past.</p>
+
+<p>"I wouldn't like to catch one of them air things on my hook an' line,"
+observed Bill, as a particularly large fish went past. "I reckon I'd
+have trouble landin' him."</p>
+
+<p>"More likely he'd pull you in," said Mark.</p>
+
+<p>For several minutes they watched the strange<span class='pagenum'><a name="Page_99" id="Page_99">[99]</a></span> procession of deep-sea
+life. Presently Jack, who was sitting near the engine room door, sprang
+up. At the same instant there was the sound of an explosion.</p>
+
+<p>"What's the matter?" cried the professor.</p>
+
+<p>"Come quick!" yelled Washington.</p>
+
+<p>"It's a fire!" yelled Jack. "One of the electrical fuses has blown out,
+and the ship is on fire!"<span class='pagenum'><a name="Page_100" id="Page_100">[100]</a></span></p>
+
+
+
+<hr style="width: 65%;" />
+<h2>CHAPTER XIII</h2>
+
+<h3>THE GHOST OF THE SUBMARINE</h3>
+
+
+<p>They all rushed toward the engine room. It was dark, because the lights
+had gone out all over the ship, and they could see only by the glare of
+the flames, which were increasing.</p>
+
+<p>"Light one of the oil lanterns!" called the professor, and Bill did so.</p>
+
+<p>"Unreel the hose," the inventor continued, and Mark and Jack ran to do
+this.</p>
+
+<p>In a few minutes the line was stretched into the engine room, and water
+was being thrown on the flames, for Washington had started the pump as
+soon as he saw the conflagration.</p>
+
+<p>The fire was in one corner, near the electrical switch board, and had
+been caused by the blowing out of one of the fuses, which occasioned the
+little explosion. The wood work near the switches was blazing fiercely,
+and soon the ship was filled with smoke.</p>
+
+<p>"Empty the ballast tanks!" called the professor. "We must rise to the
+surface!"</p>
+
+<p>"We'll all be burned up!" cried Tom. "First<span class='pagenum'><a name="Page_101" id="Page_101">[101]</a></span> we nearly smother and then
+we get on fire. Neber saw such luck!"</p>
+
+<p>With a rush the <i>Porpoise</i> began to rise, as her tanks were lightened.
+With steady hands, though with fear in their hearts, Jack and Mark
+continued to play the water on the flames, while the professor and
+Washington got out a second line and aided them.</p>
+
+<p>"The fire is dying out!" exclaimed Mr. Henderson. "We'll soon get the
+best of it."</p>
+
+<p>In five minutes the worst was over, though it had been an anxious time,
+and one of danger. The ship came to the surface, and the open man-hole
+let out the thick smoke that had nearly suffocated the travelers.</p>
+
+<p>As soon as it was cool enough in the engine room an examination was made
+of the damage done. It was not as bad as the professor had feared, and
+the running part of the ship was not harmed. A new fuse was put in and
+the electric lights turned on.</p>
+
+<p>The night was spent with the ship floating on the surface of the ocean,
+only enough speed being kept up to give her steerage way. The professor
+did not want to go below the waves until he had repaired the switch
+board.</p>
+
+<p>Watch was kept, for, though they were out of the regular line of ocean
+travel, there was no<span class='pagenum'><a name="Page_102" id="Page_102">[102]</a></span> telling when a vessel might come along and run
+them down, for the <i>Porpoise</i> did not show above the waves more than a
+few feet, and carried no lights.</p>
+
+<p>Mark had the watch just after midnight, and was sitting in the conning
+tower, the door of which opened out on the small deck. He had swept the
+surface of the water with powerful glasses and was sure there were no
+ships in sight. So, feeling that he would like to stretch his legs, he
+walked up and down on the platform.</p>
+
+<p>He had reached the after end, and was about to turn and go back, when he
+was startled to see between him and the conning tower a white object. At
+first Mark thought it was a cloud of mist, or something the matter with
+his eyes. He rubbed them, but the object did not disappear.</p>
+
+<p>Then it moved, and, to his horror Mark saw that it had the shape of a
+man, tall and thin. The two arms were outstretched, and to Mark's
+imagination seemed to be pointed toward him.</p>
+
+<p>In spite of trying not to be, Mark was frightened.</p>
+
+<p>He did not believe in ghosts, and had always felt that all stories about
+them were due to persons' imaginations. Now he saw something that was
+hard to explain.</p>
+
+<p>As he watched it, the white object turned and<span class='pagenum'><a name="Page_103" id="Page_103">[103]</a></span> glided without making the
+slightest noise, toward the conning tower. It entered and Mark breathed
+a sigh of relief.</p>
+
+<p>Perhaps, after all, it was some one from down in the cabin, maybe the
+professor himself in his night shirt, who had come up to see that all
+was right.</p>
+
+<p>"I'll go and look," said Mark to himself.</p>
+
+<p>He had to nerve himself for the ordeal, as, in spite of assuring himself
+that there were no such things as ghosts, he was frightened.</p>
+
+<p>It was absolutely quiet. The only sound was the gentle swish of the
+water against the sides of the ship. The engine was running so slowly
+that it caused no noise.</p>
+
+<p>Half way on his journey to the conning tower Mark paused. There,
+advancing toward him, was the white object. With outstretched arms it
+glided nearer and nearer until Mark's heart was beating as if it would
+burst through his ribs. His mouth was dry and he could not have cried
+out had he tried.</p>
+
+<p>There was a splash in the water off to the left as some big fish sprang
+out and dropped back again. Involuntarily Mark turned in that direction.
+Then he thought of the ghost and looked for it again. To his surprise
+the white object was nowhere to be seen!<span class='pagenum'><a name="Page_104" id="Page_104">[104]</a></span></p>
+
+<p>The boy waited a few minutes, and then, screwing up his courage, he went
+to the tower. There was no one inside, and, along the length of deck
+nothing was to be seen of the ghost.</p>
+
+<p>"I wonder if I have been asleep and dreaming," the boy asked himself. He
+gave his leg a pinch, and the sensation of pain told him he was not
+slumbering.</p>
+
+<p>"Well, I'll say nothing about it," Mark went on to himself. "They'll
+only laugh at me."</p>
+
+<p>Entering the tower Mark looked for the glasses in order to make another
+observation. He could not find them, yet he was sure he had left them on
+a shelf in the tower.</p>
+
+<p>"I wonder if the ghost took them," he said.</p>
+
+<p>He heard some one coming up the iron stairs of the small companionway
+that led down into the interior of the ship through the man-hole. At
+first he thought it was his queer midnight visitor returning. Then the
+head and shoulders of Jack appeared.</p>
+
+<p>"I've come to relieve you," said Jack. "Your watch is up; it's two
+o'clock. Here are the night glasses. I found them on the cabin table. I
+thought you had them with you."</p>
+
+<p>"I did," replied Mark.</p>
+
+<p>"Then how did they get below?"</p>
+
+<p>"I&mdash;I don't know," said Mark.<span class='pagenum'><a name="Page_105" id="Page_105">[105]</a></span></p>
+
+<p>The mystery was deepening, yet he did not want to tell Jack just yet.</p>
+
+<p>"Well, that's queer," remarked Jack. "Maybe the captain came up and got
+them while you were asleep."</p>
+
+<p>"I didn't go to sleep," answered Mark rather crossly.</p>
+
+<p>Jack said nothing more, but took his place in the conning tower, while
+Mark went below. Thinking to discover if the ghost might by any chance
+have been one of the persons on the <i>Porpoise</i>, Mark looked into each
+bunk. From the captain to Washington, all the inmates were peacefully
+slumbering.</p>
+
+<p>"Queer," murmured Jack, as he took a look into the engine room before
+turning in. The engine needed no attention, as it worked automatically,
+and all there was to do was to steer the ship. Even this needed little
+care as the course was a straight one, and the wheel could be locked,
+leaving the lookout little to do.</p>
+
+<p>"Did you see anything during your watch?" asked Mark of Jack the next
+morning.</p>
+
+<p>"See anything? What do you mean?"</p>
+
+<p>"I mean anything unusual."</p>
+
+<p>"Nothing, only a school of porpoises went past and gave me a little
+scare. They were like a lot of water kittens at play."<span class='pagenum'><a name="Page_106" id="Page_106">[106]</a></span></p>
+
+<p>Mark concluded he would say nothing of the white visitor until he
+ascertained whether any one else had seen it.</p>
+
+<p>It was several nights later, when the ship was once more proceeding
+slowly along the surface of the water, that the ghost again appeared.
+This time Washington had the midnight watch.</p>
+
+<p>But the colored man was not one to remain quiet when he had such a scary
+visitor, and his yells aroused the ship.</p>
+
+<p>"It's a ghostess! A big white ghostess!" yelled Washington. "I don seen
+it wid my eyes, an' it waved his arms at me. I's goin' to die suah!"</p>
+
+<p>"What's all this nonsense?" demanded the professor sternly. Then
+Washington, more or less excitedly, told of what he had seen. It was
+just as it had happened to Mark.</p>
+
+<p>"You were dreaming," said the professor to Washington. "There are no
+such things as ghosts."</p>
+
+<p>Every one, from old Andy to Tom and Bill, had been roused by
+Washington's cries, and listened to his story. At the close of the
+recital of how the white thing had suddenly disappeared, Washington
+refused to continue his watch, unless some one stayed with him.</p>
+
+<p>Mark volunteered to do this. He was anxious<span class='pagenum'><a name="Page_107" id="Page_107">[107]</a></span> to see if the ghost would
+reappear to him. But nothing happened; and the rest of the night passed
+off quietly.</p>
+
+<p>The next day the <i>Porpoise</i> was taken below the surface, in order to
+allow of better speed being made. She was running along, submerged to a
+depth of two hundred feet, when there came a sudden jar, and the ship
+stopped.</p>
+
+<p>"More trouble!" exclaimed the professor.</p>
+
+<p>He opened the slide covering the bull's-eye windows and looked out. All
+about was swirling muddy water.</p>
+
+<p>"Can you see anything?" the inventor called to Jack, who was in the
+conning tower.</p>
+
+<p>"We've run into a mud-bank, and are stuck fast," called back the boy.<span class='pagenum'><a name="Page_108" id="Page_108">[108]</a></span></p>
+
+
+
+<hr style="width: 65%;" />
+<h2>CHAPTER XIV</h2>
+
+<h3>DIGGING OUT THE SHIP</h3>
+
+
+<p>"Reverse the engine!" called the professor. "Maybe we can back the ship
+out."</p>
+
+<p>Washington set the big screw to revolving in the opposite direction. The
+<i>Porpoise</i> shook and shivered but the mud held her fast.</p>
+
+<p>"We must have gone in pretty deep," commented Amos Henderson. "Luckily
+it was soft mud instead of a rocky reef or we'd have damaged the ship
+beyond repair."</p>
+
+<p>For several minutes the engines were kept on the reverse, but all to no
+purpose. The sticky mud was like glue in its holding power and the ship
+had buried her prow deep into it.</p>
+
+<p>"I guess we'll have to dig our way out," said the professor, after
+taking a careful view of the big mud bank from the conning tower.
+"Washington, get out the diving suits and the spades."</p>
+
+<p>"Are we really going out in the water to dig?" asked Tom.</p>
+
+<p>"Of course," said Mr. Henderson. "You'll be as safe as in the ship,
+wearing one of my diving<span class='pagenum'><a name="Page_109" id="Page_109">[109]</a></span> suits. We'll all have to help, for it will be
+quite a task."</p>
+
+<p>The queer suits were brought out, and the reservoirs in the helmets were
+filled with compressed air. It was decided to have Washington remain
+within the <i>Porpoise</i>, to watch the machinery and start the engine when
+the digging was partly done, in order to see if the ship would not pull
+herself free when some of the mud had been removed from the prow.</p>
+
+<p>"And we may need Washington for another purpose," said the professor.</p>
+
+<p>"What for?" asked Mark.</p>
+
+<p>"Well, he'll have to stay by the diving tank, to let us in quickly in
+case of emergency."</p>
+
+<p>"Do you think there'll be an emergency?" asked Jack.</p>
+
+<p>"You never can tell," was the answer. "We are in deep water, and I don't
+want any accidents to happen."</p>
+
+<p>In a few minutes all save Washington were in their diving suits and
+ready to go out and walk on the bottom of the sea. They entered the
+tank, the door was closed, and then water was slowly admitted from the
+ocean. When the tank was full, led by the professor, they stepped out on
+the muddy floor of the ocean.</p>
+
+<p>At first the pressure of the water at so great a<span class='pagenum'><a name="Page_110" id="Page_110">[110]</a></span> depth bothered them.
+But, as we know, the diving suits were reinforced with plates of steel,
+and so strong that little more than an extra weight of water was
+noticed. They soon became used to it. Each one carried a spade, while
+the professor, Andy and the boys each had, slung about their necks by
+straps, one of the electric guns.</p>
+
+<p>Cautiously they walked toward the big mud bank. They had to go slowly
+because of the weight of the water above them, and because they might at
+any minute step into some muck hole and sink down. Fortunately, however,
+they found there was a firm bottom right up to where the bank of mud
+reared upward.</p>
+
+<p>Turning on the electric lights in their helmets, the voyagers were able
+to see quite distinctly. The <i>Porpoise</i> had rammed her nose into the
+under-water hill for a distance of about ten feet. It was going to be no
+easy matter to get her free, but the divers lost no time.</p>
+
+<p>Vigorously they attacked the big hill of mud. They dug their spades in
+and tossed the earth to one side. It was a strange place to work. At
+first the weight of water hampered every one, but they soon became used
+to it and were able to proceed more rapidly.</p>
+
+<p>From the conning tower Washington kept watch of their progress. When
+they had gone in<span class='pagenum'><a name="Page_111" id="Page_111">[111]</a></span> about five feet he started the engines, hoping the
+<i>Porpoise</i> might now pull herself free. But the mud still held.</p>
+
+<p>By signs, for it was of course impossible for any one to hear or speak,
+attired as they were in helmets and suits, the professor motioned that
+they must dig deeper.</p>
+
+<p>Once more they attacked the big mud bank with their shovels. Farther and
+farther they went into the muck until it seemed that the nose of the
+submarine must be free. But when Washington started the engines it was
+obvious that the ship was still held.</p>
+
+<p>Again the digging was resumed. All at once, while every one was wielding
+his spade to best advantage, a shadow seemed to cover the water. It
+loomed up large and black, and the professor stopped and gazed upward.
+What he saw made him drop his spade and grab the gun that was about his
+neck.</p>
+
+<p>Floating in the water above the diggers, were three immense sharks.
+Their cruel mouths were partly open, showing three rows of big teeth,
+and they were slowly turning over on their backs to make a sudden rush
+and devour the men and boys. Owing to the peculiar shape of its maw a
+shark can not bite until it turns over.</p>
+
+<p>The professor motioned for Bill and Tom to<span class='pagenum'><a name="Page_112" id="Page_112">[112]</a></span> move behind him, and
+signalled for Jack, Mark and Andy to stand close with their weapons
+ready.</p>
+
+<p>The sharks floated lazily downward as if they knew they had the diggers
+at their mercy. To run and escape was impossible, for no one could run
+hampered by the weight of water and his diving suit.</p>
+
+<p>One of the terrible fish opened its mouth wider and, with a flirt of its
+tail aimed straight for the professor. Mr. Henderson raised his gun, and
+took careful aim at the middle of the fish, half turned over. Unerringly
+the electric bullet sped on its way. It entered the soft under part of
+the shark, and immediately the thing struggled in its death agony.</p>
+
+<p>The water was dyed with blood. At the same instant the other sharks
+rushed forward in a swirl of foam. The boys and Andy fired as best they
+could, and must have hit one of the creatures for there was a greater
+commotion.</p>
+
+<p>But the fight was not over. Instantly the ocean seemed alive with the
+giant fish. Attracted by the blood of the killed ones, scores of the
+tigers of the seas rushed toward the scene of combat making matters
+livelier than ever.</p>
+
+<p>The professor, the boys and Andy fired their guns at random. Redder and
+more red became the water until their helmet lamps barely glowed<span class='pagenum'><a name="Page_113" id="Page_113">[113]</a></span> in the
+crimson sea. It seemed that a whole army of the voracious sharks had
+attacked them.</p>
+
+<p>The professor realized that to stay and attempt to fight all the sharks
+in that part of the ocean was impossible. He motioned for the boys and
+Andy to follow him. Then he slowly led the way back to the ship.</p>
+
+<p>But the sharks were not to be gotten rid of so easily. Several of the
+largest followed the diggers, their horrible eyes, and big mouths with
+rows of cruel teeth, striking terror to the hearts of all.</p>
+
+<p>One of the creatures made a rush for Bill and Tom who were close
+together. Either or both of the men would have been bitten in twain, in
+spite of the protection of their diving suits, had not Mark, with a snap
+shot, killed the fierce fish.</p>
+
+<p>It was now a running fight, and yet not so much that, because to run was
+impossible. However, they hurried all they could, and, by dint of quick
+firing kept the ugly creatures at bay until the side of the ship, where
+the diving tank was placed, was reached.</p>
+
+<p>The professor stepped to one side, and motioned for the others to
+proceed him in entering. Little time was lost. As Bill, the last one in,
+stepped past the steel door the inventor attempted to enter. To do so he
+had to let go of his gun.</p>
+
+<p>Instantly one of the sharks made a rush for the<span class='pagenum'><a name="Page_114" id="Page_114">[114]</a></span> old man. But Andy was
+on the watch. He leaned forward, and, from his weapon sent a bullet
+straight down the throat of the monster. The electric missile did its
+work well, and the lifeless body of the shark was devoured by the others
+of its tribe.</p>
+
+<p>The professor pulled the door shut behind him. Then he set the pump to
+work to empty the tank. As he did so there was a tremor to the ship.
+What could it mean?</p>
+
+<p>In a few minutes the tank was empty and the divers stepped out into the
+ship, freed from the oppressive weight of water. The ship continued to
+vibrate and seemed to be in motion.</p>
+
+<p>"What is it?" asked Mark as soon as he had his helmet off.</p>
+
+<p>"De ship am free! We've got off de mud bank!" exclaimed Washington,
+running in from the engine room.</p>
+
+<p>It was true. Enough had been dug so that, with the power of the screw
+working backward, there was sufficient force to pull the <i>Porpoise</i> from
+her perilous position.</p>
+
+<p>"Empty the tanks and rise to the surface," said the professor.</p>
+
+<p>In a few minutes the ship was on top of the waves, the adventurers freed
+from the double danger of the mud and sharks. They congratulated<span class='pagenum'><a name="Page_115" id="Page_115">[115]</a></span> each
+other on the good outcome of the fight with the monster fishes.</p>
+
+<p>Wearied with their labors and the battle under the waves, the travelers
+sat up on the deck breathing in the fresh breeze. Then, after a while,
+supper was made ready and eaten with good appetites.</p>
+
+<p>It was decided hereafter to sail along near the surface at night, and
+not to submerge the ship deeply save during daylight, when it was easier
+to distinguish objects under the water.</p>
+
+<p>Following this plan the <i>Porpoise</i> steamed along just awash that night,
+and the next day was sent down about fifty feet below the surface.</p>
+
+<p>One afternoon, when the travelers were resting, having partaken of a
+fine meal, the professor went on deck to make some observations, the
+ship having been raised for that purpose. He came down, somewhat
+excited.</p>
+
+<p>"Well, we're half way to the pole," he announced.</p>
+
+<p>"How can you tell?" asked Mark.</p>
+
+<p>"Because we have just crossed the equator. We went over the imaginary
+line three minutes ago."</p>
+
+<p>"I was wondering what made it so warm," said Jack.</p>
+
+<p>"I guess you dreamed it was hotter," spoke the professor. "It has been
+just as hot as this for<span class='pagenum'><a name="Page_116" id="Page_116">[116]</a></span> the last few days. Crossing the line makes no
+difference."</p>
+
+<p>"Then we are really in the southern hemisphere now," said Mark.</p>
+
+<p>"That's where we are," replied Mr. Henderson.</p>
+
+<p>He put his instruments away.</p>
+
+<p>"Well, we may as well go below the surface again," he remarked.</p>
+
+<p>"Come quick! Hurry up!" yelled Washington from the deck. "Dar's a
+shipwreck up heah! Somebody's on it!"<span class='pagenum'><a name="Page_117" id="Page_117">[117]</a></span></p>

+<h2>CHAPTER XV</h2>
+
+<h3>THE STRANGE SHIPWRECK</h3>
+
+
+<p>The professor, followed by the boys and Tom, Bill and Andy hastened on
+deck. They saw Washington pointing excitedly off to the west. There,
+rising and falling on the easy swell, was the wreck of a large vessel.</p>
+
+<p>She had been a three masted schooner, but now only the stumps of the
+masts remained and the craft was rolling to and fro. It had settled low
+in the water, and was quite deep by the head, so that, at times, the
+waves broke over the bow in a shower of spray.</p>
+
+<p>But what attracted the attention of the adventurers more than anything
+else was the sight of two figures near what had been the after cabin of
+the ship.</p>
+
+<p>There they stood, frantically waving their hands toward those on the
+submarine. Across the water that separated the two craft, there came a
+faint hail.</p>
+
+<p>"I suppose they are nearly dead," exclaimed the inventor. "We must save
+them."<span class='pagenum'><a name="Page_118" id="Page_118">[118]</a></span></p>
+
+<p>He ordered the <i>Porpoise</i> sent ahead slowly toward the wreck. The
+distance was about half a mile, and was soon covered. As the submarine
+approached closer those on the schooner could be observed more plainly.</p>
+
+<p>"One of 'em is a woman!" exclaimed Jack, who was using the glasses.</p>
+
+<p>"Let me see," spoke the professor.</p>
+
+<p>"You're right," he added. "The other is a little girl."</p>
+
+<p>A few minutes later the <i>Porpoise</i> was alongside. The woman and child
+came to the rail of the schooner, which was barely five feet above the
+waves.</p>
+
+<p>"Can you jump down, or shall I come aboard and get you?" asked Mr.
+Henderson seeing the woman hesitate.</p>
+
+<p>"I can jump down, if you will catch the child," said the woman. "Oh I am
+so glad you came," she added. "We are almost dead from hunger and
+thirst, and the wreck is ready to sink and cannot last many hours
+longer."</p>
+
+<p>"Pass the little girl down to me," spoke Andy. "Then you jump. We'll
+save you all right."</p>
+
+<p>The little girl reached the deck in safety, and the woman, who proved to
+be her mother, followed.</p>
+
+<p>"Now take us to your ship," said the woman.<span class='pagenum'><a name="Page_119" id="Page_119">[119]</a></span></p>
+
+<p>"You must be a long way from her, as she is not in sight."</p>
+
+<p>"Our ship is right here," spoke Mr. Henderson with a smile.</p>
+
+<p>"Where, I don't see her," and the woman looked in all directions.</p>
+
+<p>"Allow me to introduce you to Profess Amos Henderson's famous submarine,
+the <i>Porpoise</i>," spoke the inventor with a bow. "But come, let us go
+below. You must be suffering, and here I am making speeches."</p>
+
+<p>"Indeed I am hungry, and thirsty too," said the woman. "So is Nellie.
+But I thought this was merely a small boat, sent from some large ship to
+get us."</p>
+
+<p>The woman and girl descended to the cabin of the submarine, where
+Washington set before them a fine meal. Under the advice of the
+professor they partook sparingly of food and drink at first, as, having
+eaten nothing in many hours, the inventor said they must begin by taking
+a little at a time.</p>
+
+<p>As soon as they had finished and become somewhat rested, the woman told
+her story. She was Mrs. Johnson, a widow, her husband having once owned
+and been captain of the schooner that was wrecked. After his death she
+and her daughter, having become part owners of the craft, disposing<span class='pagenum'><a name="Page_120" id="Page_120">[120]</a></span> of
+a third interest to the former mate of the ship, had set out on one of
+the voyages to South American ports.</p>
+
+<p>They had had good weather going, and took on a valuable cargo of lumber
+and rare woods. But the return trip was more perilous. Heavy storms had
+buffeted the craft almost from the time of leaving port, and in one
+heavy blow, ten days before, the ship had been wrecked.</p>
+
+<p>"What became of the crew?" asked Mr. Henderson.</p>
+
+<p>"They took to the boats," replied Mrs. Johnson. "My little girl and
+myself were to go with the mate and his men. The waves were fearfully
+high, and, as they held the boat close to the schooner so we could get
+in, a big roller smashed the little craft. The men must have all been
+drowned for I never afterwards caught sight of one of them."</p>
+
+<p>"But the other boats?" asked the inventor.</p>
+
+<p>"They had gotten too far away to hail, supposing that I would be taken
+care of by the mate. There was nothing for Nellie and I to do but stay
+on board, expecting the ship to sink every minute."</p>
+
+<p>"And you have been there ever since?" inquired Andy.</p>
+
+<p>"Ever since. That was ten days ago. Every day I thought it would be our
+last. The storm<span class='pagenum'><a name="Page_121" id="Page_121">[121]</a></span> passed away and the sea became calm but the ship kept
+settling lower and lower. Only the fact that part of the cargo was wood
+kept her afloat so long. I managed to get some provisions and water up
+on deck, but the sea had spoiled most of the stuff. We had to eat only a
+little at a time, as I knew it would be some days before we could be
+rescued, if we ever were. Two days ago we ate the last of the food and
+drank almost the last of the water."</p>
+
+<p>"Then you had nothing since then," spoke Jack.</p>
+
+<p>"Only a few drops of rain that I caught on a piece of sail," answered
+Mrs. Johnson.</p>
+
+<p>"Never mind, you can have all you want now, mother," said Nellie, coming
+over to pat her parent's cheek. "Oh," the child went on, "I was so
+thirsty I could just cry when I thought of such things as ice cream
+sodas."</p>
+
+<p>"I guess you could," agreed Mark. "Well, we can't give you any soda
+water, but we have plenty of the other kind."</p>
+
+<p>Mrs. Johnson was much interested in the <i>Porpoise</i> and Professor
+Henderson showed her all about the craft. Though the quarters were
+rather cramped, a small cabin was fitted up for the lady and her
+daughter.</p>
+
+<p>"We will travel a bit under the water so you<span class='pagenum'><a name="Page_122" id="Page_122">[122]</a></span> can get used to it," said
+the captain after a tour of the ship had been made. The tanks were
+filled, and the <i>Porpoise</i> sank beneath the waves. At first Mrs. Johnson
+was much frightened, and Nellie cried. But when they saw how skillfully
+the ship was managed, and how easy it was to rise again, they lost their
+fears.</p>
+
+<p>For several days the voyage was continued. Mrs. Johnson and Nellie
+remained aboard as there was no place to land them, and they said they
+wished to stay until they met some ship sailing north.</p>
+
+<p>One day, just at dusk, when the <i>Porpoise</i>, after a long run under the
+water had come to the surface, the professor, came up on deck to take a
+look around. Washington and Andy accompanied him.</p>
+
+<p>"Looks like land, off there to the left," remarked the old hunter.</p>
+
+<p>"Get the glasses, Washington," said Mr. Henderson. "It may be a ship."</p>
+
+<p>He took a long and careful look through the binoculars.</p>
+
+<p>"It's some sort of land," he announced. "We'll go over in the morning
+and see what it is. Probably it's an island, for there's no main land in
+these parts. We are in the middle of the southern Atlantic now."<span class='pagenum'><a name="Page_123" id="Page_123">[123]</a></span></p>
+
+<p>The next morning, after breakfast, the <i>Porpoise</i> was headed toward the
+dark spot on the surface of the water that the professor had gazed at
+the evening before. As they came nearer it was seen that the place was a
+large island.</p>
+
+<p>"But it's a mighty queer one," spoke Mr. Henderson. "It looks more like
+a big volcano than anything else."</p>
+
+<p>As the ship came nearer it was seen that this was true. The island rose
+abruptly from the surface of the sea in a big ridge, slightly rounded.
+There appeared to be no signs of life on the land, but in the air
+overhead hovered several big birds. These circled about and then
+fluttered down, seemingly about the middle of the island.</p>
+
+<p>"We'll sail around and see if there's a place to land," spoke the
+inventor. "There doesn't seem to be a good harbor on this side."</p>
+
+<p>Slowly the <i>Porpoise</i> made the circuit. The island appeared to be almost
+round. When they had gone about half way around Andy, who was staring
+ahead, cried out:</p>
+
+<p>"Look out Professor! Don't go any nearer or we'll be sucked into the
+whirlpool!"</p>
+
+<p>The inventor looked where the hunter pointed. Then he beheld the
+strangest sight he had ever seen. The island was low toward where Andy
+pointed and they beheld the waters of the ocean<span class='pagenum'><a name="Page_124" id="Page_124">[124]</a></span> pouring over the edge
+of it, and falling down into an immense hole with a roar like that of
+Niagara Falls.</p>
+
+<p>"Reverse the ship!" cried Professor Henderson. "Send her back quickly,
+Washington, or we'll be sucked down!"</p>
+
+<p>The colored man lost no time, and the big screw was sent whirling in the
+opposite direction. And it was high time, for already the onward rush of
+the falling waters was slowly drawing the ship toward the big cavern.</p>
+
+<p>"That was a lucky escape," commented Amos Henderson. "Well, as we can't
+land there we'll try the other way around."</p>
+
+<p>The ship was headed in the opposite direction, and, after an hour's
+sailing, a good harbor was discovered. The <i>Porpoise</i> was anchored in
+shallow water close to the shore and in a small boat the professor, Andy
+and the two boys went to the strange island.</p>
+
+<p>They found it merely an immense circle of land with the middle part
+taken up by the big hole. And such a hole as it was! It was so wide
+across that they could not see the farther side, and the depth they
+could only guess at. Looking down they could only see great rolling
+masses of clouds or vapor.</p>
+
+<p>"Perhaps it's steam," suggested Jack.<span class='pagenum'><a name="Page_125" id="Page_125">[125]</a></span></p>
+
+<p>"Maybe it is," agreed the professor. "If this is a volcano, with lava in
+it, the water of the ocean, pouring in on the other side, may be changed
+to steam."</p>
+
+<p>"Do you suppose this hole leads to the centre of the earth?" asked Mark.
+"I've read somewhere, that the earth is hollow."</p>
+
+<p>"Some scientists believe it," commented the professor. "This looks like
+a big enough hole to lead clear through to China. Hark, you can hear the
+roar of the water now."</p>
+
+<p>They listened, and the wind brought to them the sound of the sea pouring
+down into the unfathomable depths.</p>
+
+<p>"Let's throw a big rock down," suggested Jack. "Maybe we can hear it
+strike bottom."</p>
+
+<p>With the aid of Mark he cast a big boulder down into the depths. They
+listened intently, but not the slightest sound echoed back.</p>
+
+<p>"I guess the bottom is too far away for you to hear the stone land,"
+said the professor.<span class='pagenum'><a name="Page_126" id="Page_126">[126]</a></span></p>
+
+
+
+<hr style="width: 65%;" />
+<h2>CHAPTER XVI</h2>
+
+<h3>THE GHOST AGAIN</h3>
+
+
+<p>They spent some time looking down into the hole. The masses of vapor, or
+clouds, rolled and swirled hundreds of feet below them, but never broke
+sufficiently to allow of a clear sight.</p>
+
+<p>"Well, we had better go back to the ship," remarked the professor. "We
+must continue our voyage."</p>
+
+<p>They were soon on the <i>Porpoise</i> and steaming away from the strange
+island, the inventor deciding to get far off out of the influence of the
+terrible waterfall.</p>
+
+<p>The night was, as usual, spent with the ship slowly steaming ahead on
+the surface of the water. It was getting on toward twelve o'clock and
+Washington had the watch. He was to be relieved by Jack.</p>
+
+<p>The latter had been awakened by the alarm clock at the head of his bed,
+which time-piece he had set to arouse him so that he might take
+Washington's place. Jack was just getting the sleep<span class='pagenum'><a name="Page_127" id="Page_127">[127]</a></span> from his eyes by a
+vigorous rubbing when he heard a loud yell.</p>
+
+<p>"Land a' Massy!" cried Washington from the deck above. "I's goin' t' die
+suah! De ghostess am after me ag'in!"</p>
+
+<p>Without waiting to dress, Jack sprang up the ladder and was soon out on
+the deck. He saw Washington kneeling down in front of the conning tower
+door while, at the after end of the deck, was a mysterious white object;
+the same strange shape that had been observed before.</p>
+
+<p>"I'm going to solve this puzzle!" exclaimed Jack to himself as he made a
+dive toward the object in white. "This ghost business will have to
+stop!"</p>
+
+<p>But, unfortunately for his plans, his foot slipped on the smooth steel
+deck, and he went down in a heap. When he got up the ghost was nowhere
+to be seen.</p>
+
+<p>Washington, however, was still kneeling down and praying to be spared
+from the attack of the midnight visitor. Jack limped over to the colored
+man.</p>
+
+<p>"Keep still," said the boy. "It's gone now. What was it, anyhow?"</p>
+
+<p>"Some ghost from de grabeyard," replied Washington.</p>
+
+<p>"When did you see it first?" went on Jack.<span class='pagenum'><a name="Page_128" id="Page_128">[128]</a></span></p>
+
+<p>"'Bout ten minutes ago," replied Washington.</p>
+
+<p>"Well it's gone now," said Jack, though he had to admit to himself that
+the affair was somewhat puzzling. Professor Henderson had been awakened
+by the yells of the colored man and came on deck to see what the trouble
+was. He appeared somewhat annoyed when Washington told him what had
+happened.</p>
+
+<p>"There are no ghosts!" declared the inventor in positive tones.</p>
+
+<p>"You wouldn't say so, Perfessor, if you'd seen him," spoke Washington.
+"He were all in white, tall an' slim, an' big red eyes, an' a green
+nose, an' fire comin' from his mouth an'&mdash;"</p>
+
+<p>"Nonsense," interrupted Jack. "It was nothing but a white object,
+Professor Henderson. I saw it."</p>
+
+<p>"And what do you think it was?" asked the inventor.</p>
+
+<p>"I&mdash;I can hardly say," replied Jack. "Of course I don't believe in
+ghosts, but this&mdash;"</p>
+
+<p>"It was probably a mist from the ocean," interrupted the professor.
+"Don't let me hear any more of it. Washington, go below. Your watch is
+up and Jack will take charge. I don't believe there will be any more
+ghosts."</p>
+
+<p>Nor were there that night. The <i>Porpoise</i> glided along, requiring little
+attention, and when<span class='pagenum'><a name="Page_129" id="Page_129">[129]</a></span> morning broke was several miles nearer the southern
+pole.</p>
+
+<p>The journey was continued beneath the waves and it was found much cooler
+under them than upon the surface, for the ship was in the midst of the
+equatorial heat.</p>
+
+<p>About four o'clock in the afternoon, when all was quiet aboard, there
+came a sudden yell from the engine room. Washington's voice could be
+heard calling for help. Then it died away in a groan.</p>
+
+<p>"Something has happened!" called Jack. "Washington is in trouble."</p>
+
+<p>He hurried toward where the machinery could be heard buzzing. The
+professor, with Andy and Mark followed. They expected to see the colored
+man caught in some shaft or belt, but he was nowhere in sight.</p>
+
+<p>"Perhaps he has fallen into the ocean," suggested Mark.</p>
+
+<p>"The engine room does not open into the sea," answered the professor.</p>
+
+<p>A deep groan came from some corner of the engine room.</p>
+
+<p>"There he is!" cried Jack.</p>
+
+<p>But a careful search failed to reveal Washington. Still he could be
+heard to groan at intervals. Bill and Tom came and aided in the search,
+while<span class='pagenum'><a name="Page_130" id="Page_130">[130]</a></span> Mrs. Johnson, who was worried at the unusual activity, asked what
+the trouble was.</p>
+
+<p>Captain Henderson did not tell her, for, as he said afterward, he did
+not want any women fainting away on his ship. At his request Mrs.
+Johnson went back to her cabin, and the hunt for Washington continued.</p>
+
+<p>"Here he is!" cried Jack at last.</p>
+
+<p>The boy had climbed up on a small ladder that led to the big storage
+battery tanks. He had looked down, and there, in the large metal box had
+spied the colored man on the bottom. Washington was unconscious and
+breathing heavily.</p>
+
+<p>"He has been overcome by the fumes of the sulphuric acid!" exclaimed the
+professor. "We must get him out quickly or he will die!"</p>
+
+<p>"I'll get him!" cried Andy.</p>
+
+<p>The old hunter grabbed a small step ladder that stood against the wall
+of the engine room. With this on his shoulder he climbed up the steps
+which led to the top of the storage battery tank. Then, by means of his
+ladder, he descended inside.</p>
+
+<p>He had to work quickly as the fumes were very strong, but he managed to
+hoist Washington up so that Bill and Tom, from outside, could take hold
+of him. Then the colored man was carried out on the deck, where the
+fresh air and some restoratives the professor used soon revived him.<span class='pagenum'><a name="Page_131" id="Page_131">[131]</a></span></p>
+
+<p>"Is I dead," were Washington's first words, as he sat up and looked
+about him.</p>
+
+<p>"Not this time," replied the professor. "You had a close call, though.
+How did it happen?"</p>
+
+<p>Washington explained that he started to clean the battery tank, when he
+lost his balance and fell in. He cried as he felt himself falling, but
+as soon as he struck the bottom of the tank the fumes of the chemicals
+made him unconscious. His deep breathing, which had sounded like groans,
+alone served to attract attention to his location.</p>
+
+<p>In a little while Washington was all right save for a slight weakness.
+Captain Henderson made him go to his bunk, and ordered him to remain
+there until morning.</p>
+
+<p>During the excitement over Washington's mishap all thought of steering
+the ship had been forgotten, and when Mr. Henderson went to the conning
+tower about five o'clock he found that the <i>Porpoise</i> was several points
+off her course and was headed to the east instead of to the south. How
+many miles out of her way the craft had steamed could only be guessed,
+but as she had been going wrong for nearly an hour, it must be quite a
+few the inventor calculated.</p>
+
+<p>However, he said, no great harm had been done. Even this slight accident
+would not have happened had not Bill, who was in the conning tower
+steer<span class='pagenum'><a name="Page_132" id="Page_132">[132]</a></span>ing, forgotten to put the automatic device in operation when he
+left the wheel to join in the search for Washington.</p>
+
+<p>"We'll soon make up the lost ground," said Mr. Henderson. "Another week
+or ten days ought to see us at the end of our journey."</p>
+
+<p>"And what will we do when we get there?" asked Jack.</p>
+
+<p>"We will make some important geographical and scientific observations,"
+said the professor. "Not only that, but we will have done something that
+no living person has ever accomplished. We reached the north pole,
+though we could not land on the exact spot. Let us hope we will be more
+successful regarding the south pole."</p>
+
+<p>The professor set the ship on her course again. Bill and Tom got supper
+in place of Washington, while Mrs. Johnson helped set the table.</p>
+
+<p>The meal was eaten, and then the inventor started the ship toward the
+surface, following the plan of not sailing beneath the waves after dark,
+in order to avoid accidents.</p>
+
+<p>The craft was making good speed ahead, with the big screw revolving in
+the tunnel and spurting the water from the rear, when there came a
+sudden jar, and everyone nearly toppled over from the quick stopping of
+the <i>Porpoise</i>. At the same time the forward end seemed to go up in the
+air.<span class='pagenum'><a name="Page_133" id="Page_133">[133]</a></span></p>
+
+<p>"What has happened? Are we sinking?" cried Mrs. Johnson.</p>
+
+<p>"I think we are going up," spoke the professor in cool tones.</p>
+
+<p>"In the air?" asked the lady.</p>
+
+<p>"On the land," answered the inventor. "I think we have struck shore and
+slid up on a beach."</p>
+
+<p>He ordered the engine stopped and hurried to the conning tower to make
+an observation. He turned on the searchlight and looked carefully at
+what the beams showed. Then he came back to the cabin.</p>
+
+<p>"Well, what is it?" asked Mrs. Johnson.</p>
+
+<p>"We have gone ashore, just as I supposed," said Mr. Henderson.</p>
+
+<p>"And whereabouts are we?"</p>
+
+<p>"On the coast of South America."</p>
+
+<p>"Near where?"</p>
+
+<p>"Near Terra Del Fuego, the land of fire!"<span class='pagenum'><a name="Page_134" id="Page_134">[134]</a></span></p>

+<h2>CHAPTER XVII</h2>
+
+<h3>ATTACKED BY SAVAGES</h3>
+
+
+<p>"Are we in any danger?" asked Mrs. Johnson.</p>
+
+<p>"I hope not," replied the captain. "If the ship is not strained the
+rising tide will probably float her safely, and we can continue our
+trip. We will have to wait until morning to see, however."</p>
+
+<p>"And if the ship is damaged?"</p>
+
+<p>"We will have to do what we can. We will hope for the best, madam."</p>
+
+<p>The professor went on deck. His first opinion of the accident was
+confirmed. The <i>Porpoise</i>, in emerging from the waves, had slid well up
+on a sandy shore, where she was held fast because the tide was rapidly
+falling. It would be twelve hours before there would be a chance of her
+floating again.</p>
+
+<p>The mishap had occurred because the ship had gotten off her course when
+Washington's accident occurred, and had not been set right in time.</p>
+
+<p>However, as Mr. Henderson had said, there was no particular danger,
+unless it was found that some<span class='pagenum'><a name="Page_135" id="Page_135">[135]</a></span> of the plates had been strained, which
+might cause a leak.</p>
+
+<p>The night was passed with the nose of the <i>Porpoise</i> well up on shore,
+and before morning, as the tide continued to fall, more and more of the
+craft became exposed until the whole steel body rested on the sloping
+beach.</p>
+
+<p>Jack was the first to awaken. He was up with the sun, and went out on
+the deck to take a view of the country he had often heard about. A
+stretch of wild landscape met his eyes, and to the left and right of the
+ship the waves were breaking on jagged rocks.</p>
+
+<p>"It's a good thing we didn't hit the rocks," thought the youth.</p>
+
+<p>Mark came up on deck, and the two boys looked over the scene. It was a
+strange one. Beyond the beach was a low level country, green in places,
+with now and then a patch of what looked like trees.</p>
+
+<p>"And what are those brown spots moving about?" asked Mark.</p>
+
+<p>"I guess they are herds of cattle," replied Jack. "You know South
+America is a great place for them."</p>
+
+<p>For half an hour the two lads gazed about. Except for the stern of the
+<i>Porpoise</i> all of the craft was now out of water, and one could have
+jumped<span class='pagenum'><a name="Page_136" id="Page_136">[136]</a></span> from the low deck down to a mound of white sand of the beach.</p>
+
+<p>"Let's go ashore and take a run," suggested Mark. "I've almost forgotten
+how to walk on dry land."</p>
+
+<p>"Go ahead," answered Jack. "I'm with you."</p>
+
+<p>"All right."</p>
+
+<p>The boys lost no time in getting down to the beach. They found it hard
+and firm, and made their way to the strip of grass-covered land lying
+beyond. Up and down they wandered, finding many curious and beautifully
+marked shells where the waves had washed them.</p>
+
+<p>Suddenly Jack gave a big jump and let out a yell.</p>
+
+<p>"What's the matter?" asked Mark.</p>
+
+<p>"I thought I saw one of those cocoanuts move," answered Jack, pointing
+to where several of the big shaggy fruits lay under a tree from which
+they had fallen.</p>
+
+<p>"I guess you're right," spoke Mark. "I certainly saw one of them take a
+little side step. I wonder what does it."</p>
+
+<p>As the boys watched they were surprised, to see one of the cocoanuts
+come toward them, apparently advancing without any visible means of
+locomotion.</p>
+
+<p>"This is a queer country," remarked Jack, get<span class='pagenum'><a name="Page_137" id="Page_137">[137]</a></span>ting ready to run in case
+the strangely moving cocoanut might be a warning of danger.</p>
+
+<p>"Look! There's a whole lot of them moving," cried Mark.</p>
+
+<p>Sure enough a dozen or more of the nuts began to advance toward the
+lads. The boys were not so much afraid as they were surprised. But a few
+seconds later the reason for the strange sight was made plain.</p>
+
+<p>As they looked they saw one of the nuts roll down a little mound of
+sand. Then they noticed that a big land crab was on the tiny hill and it
+was evident that the nut had fallen from his claws.</p>
+
+<p>"It's the crabs!" exclaimed Mark. "I remember reading about them now.
+They come ashore from the water where they live part of the time and get
+the cocoanuts. Then they smash the shells by pounding the nuts on a
+stone and eat the white meat inside. They are called cocoanut crabs."</p>
+
+<p>"I was beginning to think we were in some enchanted land," spoke Jack.</p>
+
+<p>"Well, it certainly looked queer," agreed Mark.</p>
+
+<p>For some time the boys watched the strange sight. Then they walked along
+the beach, seeing several large star fish, and some big horse-shoe crabs
+that had been stranded by the tide.</p>
+
+<p>"Look at that immense turtle!" exclaimed<span class='pagenum'><a name="Page_138" id="Page_138">[138]</a></span> Mark, as one of the creatures
+scuttled over the sand toward the sea. "I'll bet she's been laying
+eggs!"</p>
+
+<p>"Perhaps so."</p>
+
+<p>They made a rush for the tortoise but were not quick enough, for she
+slid into the water and made off.</p>
+
+<p>"Here's her nest, anyhow," called Jack, as he pointed to some eggs,
+thinly covered with sand. "Let's go back and take them with us. I've
+heard they are good eating."</p>
+
+<p>Jack and Mark started to gather up as many of the eggs as they could in
+their hats. While they were thus engaged they heard a call from the ship
+and looked up to see coming toward them, all of the ship's company
+except Washington.</p>
+
+<p>"I wonder if anything could have happened," spoke Mark.</p>
+
+<p>He and Jack dropped the eggs and started on a run toward the stranded
+ship. They were reassured, however, when they saw the professor waving
+his hand at them. When he got within hailing distance the inventor
+called:</p>
+
+<p>"It's all right, boys. We're just taking a little walk, before
+breakfast, for an appetizer. It's been some time since we were on land.
+Washington says he'll have some fine fried ham for us in a little
+while."<span class='pagenum'><a name="Page_139" id="Page_139">[139]</a></span></p>
+
+<p>"And here are the eggs to go with it," spoke Jack.</p>
+
+<p>"Have you found a hen house?" asked Mr. Henderson in some wonder.</p>
+
+<p>"No, but we discovered a turtle, which is just as good," replied Mark.
+The professor agreed with him, and called for Washington to come and get
+the eggs.</p>
+
+<p>"Wall I 'clare to goodness!" exclaimed the colored man as he gathered
+the product of the turtle up in his cook's apron. "Dis suttinly am a
+queer contraption of a country to find eggs growin' in de sand."</p>
+
+<p>He shuffled back to the ship, while the others walked up and down on the
+beach. In about half an hour the professor suggested that they return.</p>
+
+<p>"Washington must have breakfast ready by now," he said, "and I, for one,
+am hungry enough to enjoy it."</p>
+
+<p>They turned toward the stranded <i>Porpoise</i> but no sooner had their eyes
+taken in the sweep of the ocean that lay before them than they uttered
+cries of fear.</p>
+
+<p>Spreading out from the beach in a big half circle that enclosed within
+its curve the submarine, were three score of canoes, each one filled
+with half naked savages.</p>
+
+<p>"The natives are going to attack the ship!"<span class='pagenum'><a name="Page_140" id="Page_140">[140]</a></span> cried the professor. "We
+must hurry back or we are lost!"</p>
+
+<p>He started on the run, accompanied by the boys and men. Mrs. Johnson and
+her daughter brought up the rear. The adventurers had gone from one
+misfortune into another.</p>
+
+<p>At the top of their speed they approached the stranded ship. The natives
+saw them coming and the next instant hundreds of paddles broke the waves
+into a mass of sparkling water as the wily savages urged their canoes
+swiftly toward the submarine.</p>
+
+<p>"If we can only reach it first we can hold them off until the tide
+floats us, and then we can escape," said the professor.</p>
+
+<p>He increased his pace though the run was <ins title="Transcriber's Note: original reads 'begining'">beginning</ins> to tell on his aged
+frame. The adventurers were now within an eighth of a mile of the ship,
+but the savages were closer, and had the advantage of being able to make
+greater speed. The two forces approached nearer and nearer. Finally the
+first of the canoes reached the submerged end of the <i>Porpoise</i>.</p>
+
+<p>With wild shouts a score of the brown men leaped from the boats and
+scrambled up the steel sides. An instant later they were joined by
+several canoe loads of their companions. They swarmed up on the deck,
+and some peered down<span class='pagenum'><a name="Page_141" id="Page_141">[141]</a></span> the winding stairs that led to the interior of the
+ship.</p>
+
+<p>"Too late!" cried the professor. "They have captured the <i>Porpoise!</i>"</p>
+
+<p>"But Washington is aboard!" shouted Jack.</p>
+
+<p>As he spoke the colored man was seen clambering up out of the companion
+way. He gave one look at the wild natives who swarmed over the ship, and
+then, with a yell to be heard a long way off, disappeared below.</p>
+
+<p>The shouts and cries of the savages grew louder and they seemed to be
+doing a sort of war dance.</p>
+
+<p>"We must make one effort to drive them away," said the professor in
+desperation.</p>
+
+<p>"We haven't even a revolver," spoke Andy.</p>
+
+<p>"Let's use stones," suggested Jack, grabbing up a handful from the
+beach.</p>
+
+<p>"Look out!" yelled Mark. "They are going to shoot some arrows!"</p>
+
+<p>A second later a flight of the weapons filled the air. Fortunately the
+natives were too far away to permit the shots taking effect, but it
+showed that they intend to fight and take possession of the ship.</p>
+
+<p>Even this did not frighten Mr. Henderson. His vessel was more than life
+to him and he kept on. Several arrows fell dangerously close and he
+might have been hurt had not old Andy run after<span class='pagenum'><a name="Page_142" id="Page_142">[142]</a></span> him and induced him to
+go farther up the beach and out of harm's way.</p>
+
+<p>"They will kill Washington!" cried Jack as he thought of the colored man
+at the mercy of the savages.</p>
+
+<p>"There he comes!" yelled Mark.</p>
+
+<p>He pointed toward the ship and as they all looked in that direction they
+saw the colored man climbing out on the deck. Under one arm he bore a
+long narrow box, and in the other hand he carried one of the electric
+guns.</p>
+
+<p>"He's goin' to fight 'em!" exclaimed Andy. "He's got a gun and he will
+show 'em what's what!"</p>
+
+<p>But Washington did not seem to have any such intentions. With a yell
+that equalled the savage cries of the natives, he sprang over the side
+of the ship, onto the sand and ran toward the group of adventurers. A
+flight of arrows followed him, but he was not hit.<span class='pagenum'><a name="Page_143" id="Page_143">[143]</a></span></p>

+<h2>CHAPTER XVIII</h2>
+
+<h3>ON LAND</h3>
+
+
+<p>"Why don't he shoot his gun at 'em?" demanded Andy, capering about on
+the sand. "He could soon scare 'em off!"</p>
+
+<p>"I'm afraid Washington is too frightened to do anything like that,"
+answered Professor Henderson. "He is lucky to have escaped alive."</p>
+
+<p>"Wait until he gets here with that gun, an' I'll do some huntin' that
+will make them savages skip!" exclaimed Andy.</p>
+
+<p>In a little while Washington came up to where the others from the
+<i>Porpoise</i> stood on the beach. The colored man was panting from his run.</p>
+
+<p>"De most monstrous disproportionately extradition ob circumstantial
+occurrances dat ever transpositioned on my optical vasionariness!" he
+exclaimed as he laid his gun and the black box carefully down on the
+sand. "Ten thousand naked imps of darkness swarmin' ober de ship an' not
+a pusson to say what dey ought to do an' where dey ought t' go! It am
+suttinly terrible!"<span class='pagenum'><a name="Page_144" id="Page_144">[144]</a></span></p>
+
+<p>"Why didn't you shoot some of 'em?" demanded Andy.</p>
+
+<p>"Me?" exclaimed Washington. "What for I want t' shoot 'em? S'pose I want
+'em t' git mad at me?"</p>
+
+<p>"Well, you're a great one," went on Andy, picking up the gun. "I guess
+I'll have to take a few shots myself."</p>
+
+<p>"Yes, sah."</p>
+
+<p>From Washington the adventurers learned how the savages had silently
+come up in their canoes and surrounded the ship, gaining possession of
+it before he could make any effort at defense, even had he so desired.</p>
+
+<p>"What are we to do now?" asked Mrs. Johnson, when they had retreated out
+of sight of the savages. "The natives have possession of the boat, and
+how are we to regain her when there are so many of them?"</p>
+
+<p>"It certainly is a hard nut to crack," admitted the professor. "We will
+have to camp out on the beach for a while and see what happens. Perhaps
+they may leave the vessel when they find it will do them no good. They
+can't run her."</p>
+
+<p>"But they can tear her all apart and damage the machinery," said Jack.
+"Then we would be in a pickle."</p>
+
+<p>"Well, we won't hope for any such bad luck as<span class='pagenum'><a name="Page_145" id="Page_145">[145]</a></span> that," interrupted the
+professor. "We will look for the best."</p>
+
+<p>"When are we going to have breakfast?" asked the little girl, after a
+long wait. "I'm hungry, mother."</p>
+
+<p>"We will have it pretty soon," replied Mrs. Johnson in order to quiet
+her daughter's mind.</p>
+
+<p>"But I want it now," continued Nellie. "I'm very hungry."</p>
+
+<p>"Hush!" said Mrs. Johnson.</p>
+
+<p>"An' I had de finest brekfust what was ever invented," said Washington,
+rolling his big eyes. "Mud turkle eggs, ham, preserves, coffee&mdash;"</p>
+
+<p>"That will do, Washington," said the professor. "It only makes our
+mouths water to think about such things."</p>
+
+<p>At the mention of the turtle eggs Jack nudged Mark, and signalled him to
+walk to one side. When they were out of earshot of the others Jack said:</p>
+
+<p>"What's the matter with cooking some of the eggs that are left on the
+sand? There are plenty of them, and there is no sense in our going
+hungry."</p>
+
+<p>"How you going to cook 'em?" asked Mark.</p>
+
+<p>"I'll show you," replied Jack.</p>
+
+<p>He scooped a hollow place out in the sand until he had quite a hole.
+This he banked up with<span class='pagenum'><a name="Page_146" id="Page_146">[146]</a></span> stones until he had a small oven. By arching the
+stones over toward the top there was left a sort of circular opening.
+Over this Jack fitted a monster clam shell, with the concave side
+uppermost.</p>
+
+<p>This made an improvised stew pan. Underneath was piled small bits of dry
+drift-wood, which a match soon set on fire. In a little while the water
+in the big shell was boiling.</p>
+
+<p>"Now get some other shells for dishes," said Jack to Mark.</p>
+
+<p>Soon Mark had piled up a lot of smaller shells.</p>
+
+<p>"Help me gather some eggs now," said Jack, "and we'll put them in to
+boil. Then we'll invite the rest of the folks to breakfast."</p>
+
+<p>The two boys soon uncovered from the sand a pile of the eggs, and in a
+little while they were steaming in the hot water. Then Jack arranged the
+shell-dishes on the sand. He went over to where the others were gloomily
+considering their plight.</p>
+
+<p>"Breakfast is ready," he announced.</p>
+
+<p>"This isn't any time for joking," spoke Professor Henderson, rather
+sternly.</p>
+
+<p>"But I mean it," went on Jack. "Just come over and see. I'm not fooling
+you."</p>
+
+<p>Wondering what he had done they all followed him.</p>
+
+<p>"Welcome to Hotel Terra del Fuego!" cried<span class='pagenum'><a name="Page_147" id="Page_147">[147]</a></span> Mark. "We haven't much of a
+variety, but what there is we can recommend."</p>
+
+<p>He began to dip the eggs out of the water with a bit of shell and placed
+them on the improvised dishes.</p>
+
+<p>"Everyone sit down," commanded Jack. "The bill of fare is ready."</p>
+
+<p>They all joined in the short laugh that followed, and soon were seated
+in a circle about the beach-oven. The eggs proved to be very good, even
+though there was no pepper. The salt of the sea water they were boiled
+in was more than sufficient.</p>
+
+<p>"Now if there was only bread in that ammunition bag Washington brought
+with the gun," said Andy, "we wouldn't want a better meal."</p>
+
+<p>"He'p yo'se'f!" exclaimed the colored man with a grin as he extended a
+canvas bag that was tied to the stock of the electric gun.</p>
+
+<p>The old hunter opened it and found it filled with ship biscuits.</p>
+
+<p>"Well I am stumped!" he exclaimed.</p>
+
+<p>"I grabbed up de wrong thing in my haste," Washington explained. "I
+thought I had de electrical lightning bullets, but I didn't. Howsomever
+de gun's got some in de chamber."</p>
+
+<p>"It's a lucky mistake," commented the professor as he munched a biscuit
+and an egg. "Bullets are good but these are better, when one is
+hungry."<span class='pagenum'><a name="Page_148" id="Page_148">[148]</a></span></p>
+
+<p>They managed to make a fairly good meal, so that even hungry Nellie was
+satisfied. The boys found a spring of fresh water up on shore, and this
+furnished something to drink, for which they were grateful.</p>
+
+<p>They sat about on the beach, after the breakfast and discussed what they
+had better do. It was evident that an attempt to regain possession of
+the ship, with their small force and only one weapon, was out of the
+question.</p>
+
+<p>"We've got to use strategy," said Andy. "If we could play some trick on
+the savages we might scare them away. Otherwise I don't see what we are
+to do."</p>
+
+<p>"It's a bad state of affairs," replied professor Henderson. "Even if we
+got the ship we might find it so badly damaged that it would be
+impossible to run it. It is a terrible thing," and he heaved a deep
+sigh.</p>
+
+<p>The hours passed with no change in the situation. The savages remained
+in possession of the submarine, and did not seem inclined to quit the
+vessel. Most of them were inside, but quite a number paddled about the
+stranded craft in their canoes.</p>
+
+<p>There was nothing for the adventurers to do but to await developments.
+With no chance of attacking the force of natives, they might consider<span class='pagenum'><a name="Page_149" id="Page_149">[149]</a></span>
+themselves lucky if the savages did not come ashore to give battle.</p>
+
+<p>The sun was high in the heavens when, in the shade of a big tree where
+they had all taken refuge from the heat, Nellie again announced that she
+was hungry.</p>
+
+<p>"I guess the boys will have to provide another meal," said Mr.
+Henderson.</p>
+
+<p>Jack and Mark said they guessed they could find some more turtle eggs,
+and Washington volunteered to accompany them. As they were looking for a
+nest in the sand they saw one of the tortoises scurrying down to the
+ocean.</p>
+
+<p>"Git her, quick!" cried the colored man. "Turn her ober on her back!"</p>
+
+<p>The boys did so, though they did not know what Washington's object was.
+The big animal lay bottom side up, vainly moving its flippers. In a few
+minutes Washington had killed the turtle and cut it out of the shell.</p>
+
+<p>"Now we'll hab turtle soup!" he exclaimed.</p>
+
+<p>Soon the fire was again blazing in the improvised stove, and a little
+later an appetizing smell filled the air. Washington had made the soup,
+and, in addition, had cooked a number of the turtle eggs.</p>
+
+<p>Big clam shells again served for dishes and a better meal than the
+breakfast was served.</p>
+
+<p>"Now if we only had some dessert," spoke Mr.<span class='pagenum'><a name="Page_150" id="Page_150">[150]</a></span> Henderson in a joking
+tone, "we wouldn't want much more. But I suppose dessert is out of the
+question."</p>
+
+<p>Jack and Mark looked at each other and, without a word went off toward
+the woods. In a little while they came back, their arms filled with
+cocoanuts.</p>
+
+<p>"How will these do for dessert?" asked Jack.</p>
+
+<p>"Fine!" cried Mr. Henderson.</p>
+
+<p>The fruit was broken open with stones and the delicious milk and soft
+pulp eaten with much relish. Then the adventurers stretched out beneath
+the trees and rested. The thoughts of each one were busy with plans for
+recovering the submarine, though no one seemed to be able to suggest any
+thing.</p>
+
+<p>It was getting dusk, when, somewhat discouraged over the result of the
+visit of the savages, they were all seated on the beach. They were
+beginning to think again of something to eat when Andy Sudds, discovered
+the long black box which Washington had brought with him in his flight
+from the <i>Porpoise</i>, and dropped in a hollow.</p>
+
+<p>"I suppose you've got something very fine in there, Washington?"</p>
+
+<p>"I declare to goodness I don't know what dat air contraption am
+conglomerated with," said the colored man. "I jest grabbed it up and
+run."<span class='pagenum'><a name="Page_151" id="Page_151">[151]</a></span></p>
+
+<p>The old hunter had, in the meanwhile, taken the cover off.</p>
+
+<p>"What in the world have we struck," he exclaimed.</p>
+
+<p>"Sky rockets!" cried Jack, with a glance at the contents of the box.</p>
+
+<p>"Yes," said Professor Henderson. "I took some aboard in case we might
+have to signal for help on the water."</p>
+
+<p>"Hurrah!" yelled Andy.</p>
+
+<p>"What's the matter?" asked Jack.</p>
+
+<p>"We'll use the sky rockets as weapons against the natives!" shouted the
+old hunter, capering about on the sand.<span class='pagenum'><a name="Page_152" id="Page_152">[152]</a></span></p>
+

+<h2>CHAPTER XIX</h2>
+
+<h3>REGAINING THE SHIP</h3>
+
+
+<p>At first the others did not know what he meant. Andy seemed much
+excited, and for a time the professor thought the heat and worry might
+have affected the hunter's mind.</p>
+
+<p>"We'll show 'em a thing or two!" cried Andy. "I once scared a lot of
+Indians this way so they didn't know whether they were on their head or
+their feet. Hurrah!"</p>
+
+<p>"What are you talking about?" asked Mr. Henderson. "Hadn't you better
+sit down and rest a bit?"</p>
+
+<p>"I'm all right," replied Andy. "I'm talking about those sky rockets.
+They'll be better than bullets. You see," he went on, "after it gets
+dark we'll shoot the rockets over the ship. The savages will think they
+are in the midst of a lot of falling stars, and if they don't take to
+their boats and leave us the ship I'll miss my guess, that's all."</p>
+
+<p>"Good!" exclaimed the inventor. "We'll try it."</p>
+
+<p>The rockets were taken out and examined.<span class='pagenum'><a name="Page_153" id="Page_153">[153]</a></span> They were big affairs of
+several pound weight and were intended for far-off signalling at sea.</p>
+
+<p>Andy, with the aid of the boys, Tom and Bill, soon constructed a rough
+sort of support from which to set off the fire-works. As soon as it grew
+dark, which it did about seven o'clock, preparations were made to try
+the experiment.</p>
+
+<p>With a whizz and roar the first rocket went sailing skyward. Up through
+the black night it went, trailing behind it a shower of fire and sparks.
+Then, with a loud report like that of a gun it burst directly over the
+ship and a rain of brilliantly colored globes of flame descended.</p>
+
+<p>"Shot number one!" cried Andy, who was setting off the rockets.</p>
+
+<p>For a few seconds after the first flight there came no sound from the
+natives at the ship. Then, just as the second rocket was set off there
+issued a long-drawn howl, which was succeeded by cries of fear.</p>
+
+<p>"We've waked 'em up!" shouted Jack.</p>
+
+<p>In rapid succession several more rockets were sent over the <i>Porpoise</i>.
+By the light of them could be seen a mass of natives crowded out on the
+small deck, while others were in their canoes.</p>
+
+<p>"I think I'll try it a little lower this time," remarked Andy. "Maybe I
+can hit some of 'em!"</p>
+
+<p>He slanted the support closer to the ground and<span class='pagenum'><a name="Page_154" id="Page_154">[154]</a></span> set off two rockets at
+once. Straight across the sandy beach they flew, directly toward the
+crowd of natives on the ship. Right into the midst of the savages the
+trailing comet of fire shot, with a hiss, roar and sputter that was
+enough to strike terror into the bravest heart.</p>
+
+<p>There was a long piercing howl of fear. Then, as the natives felt the
+hot sparks scatter over their half-naked bodies, they broke into a wild
+stampede. Over the side of the ship they plunged, into the sea, and swam
+off. Those in boats paddled quickly away.</p>
+
+<p>For good measure Andy sent another rocket into the midst of the fleeing
+ones, and this served to quicken their departure. By the light of the
+last one it could be seen that the ship was deserted, though the water
+all about her was black with the swimming savages, and the canoes.</p>
+
+<p>"I guess they won't come back in a hurry!" cried Andy. "Come on! We'll
+board the ship now, and get the electric guns to ward off any further
+attacks!"</p>
+
+<p>"That's the talk!" cried Mark.</p>
+
+<p>Toward the <i>Porpoise</i> all started on a run. As they neared her they
+found that the rising tide had floated her.</p>
+
+<p>"We must see if the natives damaged her," spoke Mr. Henderson as soon as
+he set foot on<span class='pagenum'><a name="Page_155" id="Page_155">[155]</a></span> deck. "If they have it will be a hard matter to make
+repairs so far from civilization."</p>
+
+<p>A hasty examination, however, showed that the savages had disturbed
+little. The engine was soon set in motion, and, in ten minutes the ship
+was steaming away from the coast, headed toward the south, the goal they
+were so eagerly seeking.</p>
+
+<p>As soon as they were well out to sea, and all sight of the canoes of the
+savages had been lost, supper was served, and all brought good appetites
+to the table. For, though the improvised meals on shore had tasted good,
+there had not been much to them.</p>
+
+<p>For several days the <i>Porpoise</i> was kept on her course, sailing along
+under the water by day, and upon the surface at night. It was one
+pleasant afternoon, while Nellie, Jack and Mark were sitting out on the
+deck, during one of the times when the boat had risen to the surface to
+renew the air supply, that a strange commotion was observed off their
+lee. The ocean seemed to be boiling.</p>
+
+<p>"What is that?" asked the little girl.</p>
+
+<p>The two boys looked to where she pointed. Indeed the ocean seemed to be
+bubbling up and down in a strange manner.</p>
+
+<p>"It's a school of porpoises," said Jack.</p>
+
+<p>Just then the water became alive with big fish. They leaped over each
+other, springing high into<span class='pagenum'><a name="Page_156" id="Page_156">[156]</a></span> the air and falling back into the sea with
+resounding splashes.</p>
+
+<p>"They're not porpoises! They're whales! Baby whales!" yelled Mark. "Look
+out or some of the big ones may ram the boat!"</p>
+
+<p>As he spoke the water all about the submarine was seen to be fairly
+swarming with the small whales. There were scores of them, and, at
+times, they were so thick that it appeared possible to walk out upon
+them without getting very deep into the water.</p>
+
+<p>Suddenly the ship careened to one side and the sea rushed over the deck.
+It was evident that one of the big whales, which were deeper down in the
+water, had struck the vessel.</p>
+
+<p>Nellie screamed and tried to grab the hand rail that was about the
+platform. She missed her grip. The next instant she was floundering in
+the ocean, in the midst of the school of whales.</p>
+
+<p>"Man overboard!" yelled Jack, remembering vaguely that he had read this
+was the proper call to make in case of accident.</p>
+
+<p>His cry brought Washington and the professor up the companionway on the
+jump.</p>
+
+<p>"Launch the boat!" cried the inventor as he saw what had happened.</p>
+
+<p>Mark was already in action. At the first sight of Nellie slipping over
+the side he had thrown off<span class='pagenum'><a name="Page_157" id="Page_157">[157]</a></span> his coat, broken the laces of his shoes in
+order the more quickly to remove the foot coverings, and had dived into
+the swirling water which surrounded the submarine.</p>
+
+<p>He struck out in the direction where the little girl had disappeared,
+and as her golden head appeared above the mass of foam he yelled in
+encouragement.</p>
+
+<p>By this time the small boat was launched and the colored man and Jack
+were pulling toward him. Mark succeeded in reaching Nellie as she was
+going down the second time. He grabbed her long locks and managed to
+keep her up until the little craft was alongside of him.</p>
+
+<p>"Git in quick, 'fore dem whales eat yo' up!" cried Washington.</p>
+
+<p>He hauled the unconscious child in first, and then Jack gave Mark a
+hand. As if by magic all the whales had disappeared and the sea was
+quiet again. In a few minutes the rescuers and the rescued one went back
+again on the <i>Porpoise</i>, where Professor Henderson soon brought Nellie
+around again. Beyond the shock and wetting neither she nor Mark was
+harmed.</p>
+
+<p>It was Jack's watch on deck that night. He had the tour from eight until
+twelve o'clock and when, about ten, every one but himself had retired,
+he took his position in the door of the conning<span class='pagenum'><a name="Page_158" id="Page_158">[158]</a></span> tower and prepared to
+pass the time as best he could.</p>
+
+<p>The ship was moving along at half speed, and, as the automatic steering
+attachment was working Jack had little to do. He sat looking at the
+stars that twinkled in the sky, the blazing Southern Cross showing among
+the constellations, when he heard a slight noise near the companionway.</p>
+
+<p>He looked in that direction and, to his horror, he saw the ghostly white
+shape that had, on previous occasions, caused him and the others fright.</p>
+
+<p>At first the boy resolved to shut himself up in the tower and wait until
+the uncanny thing had disappeared. Then his courage came back and he
+thought he would try to solve the mystery.</p>
+
+<p>He argued that if the <ins title="Transcriber's Note: original reads 'wierd'">weird</ins> white object was human and could witness his
+movements the best thing to do would be to try and creep upon it
+unobserved. On the contrary, if the ghost was some natural phenomenon,
+or a supernatural agent, all he could do would be of no avail.</p>
+
+<p>So he decided the best thing to do would be to crawl upon the thing,
+keeping as near to the deck as possible and trying to hide himself. With
+this in view he put on a long rain coat that hung in the conning tower,
+and then, like a snake, commenced to wiggle his way toward the middle of
+the platform where the white object still stood.<span class='pagenum'><a name="Page_159" id="Page_159">[159]</a></span></p>
+
+<p>Nearer and nearer to it Jack came. His heart was beating fast and he was
+much frightened, but he nerved himself to continue. As he came closer he
+could see that the object looked more and more like a man, completely
+robed in white garments.</p>
+
+<p>Jack was now within ten feet of the strange object. It was a man, he was
+sure of it, but whether a present or former inhabitant of the earth he
+could not decide. Jack's hair was beginning to raise. A cold shiver ran
+down his spine as the white thing lifted an arm and seemed to point
+directly at him. At the same time it groaned in a deep tone.</p>
+
+<p>Jack let out a yell that could be heard all over the ship. He made a
+spring for the object, determined to discover what it was or die.</p>
+
+<p>At that instant the whole ship seemed to rise in the air. It left the
+water and began moving skyward. Right out of the waves the <i>Porpoise</i>
+was lifted until the big screw was clear of the water and it was
+churning around in the tunnel without any resistance, racing at top
+speed now that it had no water to thrust against.</p>
+
+<p>Then the ghost seemed to vanish into thin air, and Jack felt himself
+falling down the hatchway.<span class='pagenum'><a name="Page_160" id="Page_160">[160]</a></span></p>

+<h2>CHAPTER XX</h2>
+
+<h3>ON A VOLCANIC ISLAND</h3>
+
+
+<p>In an instant the ship was in confusion. The professor, followed by old
+Andy, Washington, Mark, Bill and Tom, came rushing from their berths,
+all in their night clothing, to see what the trouble was. They met in a
+tangled mass, stumbling over Jack at the foot of the steps.</p>
+
+<p>"Is the ship on fire?" called Mrs. Johnson from her cabin.</p>
+
+<p>"I hope not!" called the professor. "But something has happened. Don't
+be frightened!"</p>
+
+<p>By this time Jack, who had been somewhat stunned, recovered his senses
+and worked his way out of the mass of bodies.</p>
+
+<p>"The ghost! The ghost!" he cried. "I saw him again!"</p>
+
+<p>"Land a' massy!" yelled Washington.</p>
+
+<p>"What has happened to the ship?" cried the professor. "Is it a tidal
+wave?"</p>
+
+<p>"I was on deck," panted Jack. "I saw the white thing! I crept up on it!
+All at once the ship rose in the air!"<span class='pagenum'><a name="Page_161" id="Page_161">[161]</a></span></p>
+
+<p>"And it's still rising!" shouted the inventor. "I must see what this
+means!"</p>
+
+<p>He made his way to the deck, and his loud shout soon brought the others
+up to him.</p>
+
+<p>"Shut off the engine!" Mr. Henderson called down to Washington, who
+hurried to obey.</p>
+
+<p>"What has happened?" asked Andy, rushing towards him.</p>
+
+<p>"We have run upon an island," answered the professor. "This is the worst
+thing that has yet happened to us."</p>
+
+<p>"What sort of an island is it that shoots you up in the air?" asked the
+old hunter.</p>
+
+<p>"It's hard to say," replied Mr. Henderson. "We will have to wait until
+morning to find out."</p>
+
+<p>The boys and men went up on deck and there beheld a curious sight. The
+<i>Porpoise</i> had been lifted bodily from the surface of the ocean where
+she had been sailing and was now raised about ten feet above the crest
+of the billows. It was too dark to see the extent of the island she
+rested on, but, from the circle of foam around the outer edge it did not
+appear to be very big.</p>
+
+<p>The excitement occasioned by the appearance of the ghost, Jack's yells
+and fall, and the rising of the ship, had subsided somewhat. Mrs.
+Johnson and her daughter, who were much frightened, were assured there
+was no immediate danger, and the<span class='pagenum'><a name="Page_162" id="Page_162">[162]</a></span> men and boys put on more substantial
+clothing than that of their night robes.</p>
+
+<p>It seemed as if morning would never come, but at length there was a pale
+light in the east and soon it changed to a rosy glow, showing that the
+sun was coming.</p>
+
+<p>The professor was early on deck, and Mark and Jack were not far behind.
+As soon as it was light enough they could see that the ship was held
+fast on top of a small rocky isle, about one hundred feet in diameter,
+which rose abruptly from the water.</p>
+
+<p>"It's a volcanic island," decided the professor. "We are in the midst of
+<ins title="Transcriber's Note: original reads 'subterreanean'">subterranean</ins> disturbances and this is probably one of the effects of
+some under-sea eruption. The pinnacle of rock rose from the ocean,
+forced up by some power underneath, just as our ship came over it. That
+accounts for the sudden rising into the air of the <i>Porpoise</i>. No wonder
+we were all scared."</p>
+
+<p>"The next question," began old Andy, "is how are we to get off?"</p>
+
+<p>"That's the point," agreed Mr. Henderson. "Here we are, high and dry,
+and we might as well be a broken flying machine as a submarine for all
+the power we have."</p>
+
+<p>"Will we have to stay here forever?" asked Nellie, who had come up on
+deck.<span class='pagenum'><a name="Page_163" id="Page_163">[163]</a></span></p>
+
+<p>"I hope not," answered the professor, smiling for the first time since
+the accident. "We will find a way to get down, never fear, little girl."</p>
+
+<p>"I suppose we might dig some sort of a canal down to the water,"
+remarked Jack. "If we could we might float the ship."</p>
+
+<p>"I'm afraid you'd find it slow digging through this volcanic rock,"
+answered Andy. "It's like flint."</p>
+
+<p>"Well, there's no use worrying over it," went on the professor in as
+calm a tone as he could muster. "It's time for breakfast, and we have to
+eat whether we're on the top of an island that shoots out of the water
+when you least expect it, or sailing along as we ought to."</p>
+
+<p>Accordingly Washington prepared the morning meal, and they all found
+they had appetites for it, in spite of their fright. Afterward they all
+came on deck again and looked about them.</p>
+
+<p>They were in the midst of a wild waste of water. Not a sign of land
+could be seen in any direction, and there was no evidence of a sail or
+steamship as far as the horizon showed.</p>
+
+<p>The little island which held the <i>Porpoise</i> so close a prisoner was a
+mere speck in the vast ocean, but it was large enough to put an end,
+temporarily at least, to the progress of the powerful submarine.</p>
+
+<p>The professor and the boys went over the side<span class='pagenum'><a name="Page_164" id="Page_164">[164]</a></span> and climbed down to the
+rock. Then the inventor verified his surmise that the rocky point was of
+volcanic origin. It was also seen that there was little chance to get
+the craft back into the ocean.</p>
+
+<p>"I guess we're doomed to stick here for some time," remarked Mr.
+Henderson, with a grim smile. "The rock has caught us squarely and
+nothing short of dynamite will free us. To use the explosive might mean
+the destruction of the ship, and I dare not risk it."</p>
+
+<p>Gloom settled over the party in spite of the efforts the professor made
+to be cheerful. Washington, after the first few minutes of fright,
+regained his usual good spirits, but, no matter how he laughed and
+joked, there was a feeling of terror in every heart.</p>
+
+<p>They realized their helplessness, and knew that unless another upheaval
+of nature occurred there was small likelihood of their release.</p>
+
+<p>On the third day of their strange adventure Professor Henderson resolved
+on a bold step.</p>
+
+<p>"We must use dynamite," he declared. "If we stay here on this desolate
+rock we are bound to perish sooner or later, for our food cannot last
+many months, though we have a large supply. We are out of the path of
+steamers and only by chance would one pass here. With care we may be
+able to blast the rock so that the ship will not be<span class='pagenum'><a name="Page_165" id="Page_165">[165]</a></span> permanently
+damaged. What do you all say? I would like your advice, for this
+concerns all of us."</p>
+
+<p>One after the other all said they were willing to abide by whatever the
+inventor did. Accordingly he made his preparations. Washington, with a
+hammer and chisel, was set to cutting a fair sized hole in the big rock,
+as far away from the ship as possible.</p>
+
+<p>He was two days at the job, and, during this time those on the stranded
+<i>Porpoise</i> watched in vain for the sight of a vessel.</p>
+
+<p>"I am going to put the dynamite in," announced Mr. Henderson one
+morning. "We must all get into the small boat and row some distance
+away, as there is no telling what the result of the explosion may be."</p>
+
+<p>"Suppose the submarine is destroyed?" asked Mrs. Johnson.</p>
+
+<p>"Then we will have to sail for the nearest land in the small boat,"
+replied the captain. "I will provision it and we will take all the
+precautions we can."</p>
+
+<p>It was with anxious hearts that the little party embarked in the little
+craft that was carried on the <i>Porpoise</i>. It was barely large enough to
+hold them. The professor was the last in, and he lighted a long fuse
+that led to the dynamite before<span class='pagenum'><a name="Page_166" id="Page_166">[166]</a></span> taking his seat. Then with Tom and Bill
+at the oars the little craft moved away.</p>
+
+<p>"How long before the explosion will take place?" asked Jack.</p>
+
+<p>"I timed the fuse for ten minutes," answered Mr. Henderson. "That will
+enable us to get far enough away so we will not be swamped by a wave."</p>
+
+<p>Five minutes later Mark, who was intently watching the volcanic rock,
+gave a loud cry.</p>
+
+<p>"There she goes!" he shouted.</p>
+
+<p>They all looked to behold a wonderful thing. As easily as though it was
+some conjuring trick the rock began to settle down in the water. Lower
+and lower it went until only the tallest jagged points showed above the
+waves, whose crested tops the keel of the ship now almost touched.</p>
+
+<p>"That isn't the explosion!" exclaimed the professor. "The fuse has not
+had time to get to the powder yet."</p>
+
+<p>"But the rock is disappearing!" yelled Andy.</p>
+
+<p>As he spoke the big pile of volcanic stone vanished completely and the
+<i>Porpoise</i> floated easily on the surface of the sea.</p>
+
+<p>"Hurrah!" cried Mark.</p>
+
+<p>"It am de most kloslostrous occurranceness dat eber transpositioned
+itself!" exploded Washington.<span class='pagenum'><a name="Page_167" id="Page_167">[167]</a></span></p>
+
+<p>"Let's row back to the ship now!" cried Mark.</p>
+
+<p>"Not yet!" said the professor quickly. "The dynamite has not gone off
+yet."</p>
+
+<p>"There it goes now," remarked Jack.</p>
+
+<p>At that instant a big column of water shot upward and a dull rumbling
+could be heard. A few seconds later the little boat rocked violently
+from the effects of the waves. Then the sea became calm, and the
+<i>Porpoise</i> could be seen dancing up and down on the heaving billows.</p>
+
+<p>"Now we can go back in safety," spoke Mr. Henderson, and Tom and Bill
+bent to the oars.</p>
+
+<p>"What happened?" asked Mrs. Johnson. "The rock seemed to disappear
+before the explosion occurred."</p>
+
+<p>"That's exactly what it was," explained the inventor. "By some strange
+freak of nature the volcanic mass dropped back into the ocean a little
+before I was ready to blow it to pieces. In settling down it lowered the
+ship. Then the explosion occurred beneath the waves. If I had waited a
+little while I need not have risked the dynamite."</p>
+
+<p>"Well, there was no guarantee that the rock would go back where it came
+from," remarked Jack.</p>
+
+<p>"No, we had to act," agreed the professor. "But now let us go aboard."</p>
+
+<p>They rowed back to the <i>Porpoise</i>, which they<span class='pagenum'><a name="Page_168" id="Page_168">[168]</a></span> found had sustained no
+damage from the queer experience it had been through.</p>
+
+<p>The motors were set in motion and in a little while the craft was again
+moving through the water out of the dangerous vicinity of the volcanic
+area.</p>
+
+<p>"Who has the two watches to-night?" asked Mr. Henderson after supper had
+been served.</p>
+
+<p>"Washington and Andy," answered Jack, who kept track of the matter.</p>
+
+<p>"I guess we'll change it, and have you and Mark take them," went on the
+captain. He gave Jack a peculiar look, and made a sign to him not to say
+anything. Wondering what was to come Jack went up on deck to watch the
+sunset.<span class='pagenum'><a name="Page_169" id="Page_169">[169]</a></span></p>
+
+
+
+<hr style="width: 65%;" />
+<h2>CHAPTER XXI</h2>
+
+<h3>CAUGHT IN A WHIRLPOOL</h3>
+
+
+<p>The boy was joined a little later by the captain, who, coming close to
+him whispered:</p>
+
+<p>"I am going to try to discover the ghost to-night. That is why I wanted
+you boys on hand to help me. This thing must be stopped if it is a joke,
+and, if it isn't&mdash;"</p>
+
+<p>"Do you think it is some one playing tricks?" asked Jack.</p>
+
+<p>"I don't know what to think," answered Mr. Henderson. "We will see what
+happens to-night."</p>
+
+<p>Mark came on deck a little while, and the three talked of the strange
+appearances of the mysterious white object. The boys told of their
+experiences, and Jack related more fully his on the night the ship went
+up on the big rock upheaval.</p>
+
+<p>"I don't believe in ghosts," said Mr. Henderson, "I'm going to lay this
+one," and he smiled grimly.</p>
+
+<p>Night settled down. Jack, who had the first tour under the new
+arrangement, had made himself<span class='pagenum'><a name="Page_170" id="Page_170">[170]</a></span> comfortable in the conning tower, and Mr.
+Henderson had hidden himself in the companionway. His idea was to thus
+guard both openings into the ship and ascertain whether the ghost came
+from within or without the craft.</p>
+
+<p>Up to a short time before twelve o'clock nothing out of the ordinary
+happened. The only sound was the lapping of the waves on the steel sides
+of the <i>Porpoise</i>, and now and then a splash as a big fish leaped out of
+the water. There was only the slightest breeze.</p>
+
+<p>Jack who, somehow or other, felt much sleepier than usual, caught
+himself nodding several times. Once he awoke with a start and realized
+that he had been dozing.</p>
+
+<p>"Come, come," he remarked to himself, "this will not do at all. This is
+a fine way to watch for a ghost."</p>
+
+<p>He remained wide awake for perhaps five minutes. Then he was off to the
+land of nod again. He was just dreaming that he was skating on a pond
+and was playing snap the whip with a lot of boys, when he awoke with a
+start.</p>
+
+<p>He felt something pressing on his chest and to his horror, as he looked
+up, he saw a big towering white object standing over him. A second
+glance showed him it was a man, or the semblance of one, and the thing's
+foot was on his chest.<span class='pagenum'><a name="Page_171" id="Page_171">[171]</a></span></p>
+
+<p>With a terrified scream Jack sprang up, upsetting the ghost, which, the
+boy thought at the time, seemed rather heavy for an unearthly spirit.</p>
+
+<p>"Did you catch it?" cried the professor.</p>
+
+<p>"No! Yes! I don't know!" yelled Jack, struggling to his feet in time to
+see the white object glide down the stairs that led from the conning
+tower into the forward cabin.</p>
+
+<p>"Run after it! We must solve the mystery!" cried Mr. Henderson springing
+from the companionway up on deck.</p>
+
+<p>But at that moment the ship began to whirl about in a circle slowly at
+first, but with increasing speed until Jack and the professor felt sick
+and dizzy. All about the water seemed to be bubbling and boiling, while,
+at the same time, there arose on the air a mournful howl.</p>
+
+<p>The professor jumped to the rail and looked over the side. What he saw
+made him recoil with horror.</p>
+
+<p>"Quick! Close the man-hole hatch!" he cried. "Shut the door of the
+conning tower!"</p>
+
+<p>"What is it?" Jack managed to ask.</p>
+
+<p>"We are caught in a whirlpool!" Mr. Henderson yelled as he leaped down
+the companionway and pulled the heavy steel cover after him.</p>
+
+<p>Stricken with a nameless dread, Jack closed the water-tight door of the
+conning tower and made<span class='pagenum'><a name="Page_172" id="Page_172">[172]</a></span> his way to the cabin. He could hardly get down
+the stairs, so swiftly was the ship whirling about.</p>
+
+<p>He found the captain busy in the engine room and, in response to calls,
+Washington and Mark came hurrying in. They had been awakened by the
+commotion and the strange movements of the <i>Porpoise</i>.</p>
+
+<p>"Turn on all the lights," ordered the inventor. "We must prepare for the
+worst."</p>
+
+<p>The incandescents were soon glowing and in the glare the frightened
+adventurers gathered about Mr. Henderson, wondering what new terror had
+befallen them.</p>
+
+<p>"See!" exclaimed the inventor. "We are going comparatively slow now, but
+we are on the outer edge. Wait until we reach the centre."</p>
+
+<p>He pointed to a compass and, as the needle pointed steadily to the north
+the card seemed to be going around like the hands of a clock that has
+lost the balance and escapement wheels. The ship made three complete
+circles a minute.</p>
+
+<p>Pale and frightened, Mrs. Johnson came from her cabin, whence the
+terrified cries of Nellie could be heard.</p>
+
+<p>"Are we sinking?" she asked.</p>
+
+<p>"Sinking will never harm the <i>Porpoise</i>," replied Mr. Henderson. "This
+is something decidedly worse."<span class='pagenum'><a name="Page_173" id="Page_173">[173]</a></span></p>
+
+<p>"I know! It is a whirlpool!" exclaimed the lady.</p>
+
+<p>"I'm dizzy; I'm so dizzy!" wailed Nellie. "Please stop the ship from
+going round, Mr. Henderson."</p>
+
+<p>She came from her bed crying, and all her mother could do did not quiet
+her.</p>
+
+<p>Meanwhile the submarine continued to whirl about faster and faster in
+the swirling waters. Five times each minute now it made the circuit,
+and, like the coils of a boa constrictor that is enfolding its victim,
+the circles continually grew smaller.</p>
+
+<p>"We are being sucked down," said Jack in a low tone as he glanced at the
+depth gage, and noted that it showed them to be thirty feet under water.</p>
+
+<p>"That is so," remarked Mr. Henderson quietly.</p>
+
+<p>"What will be the result?" asked Mrs. Johnson.</p>
+
+<p>"I do not know," was the answer, and the captain turned aside. He seemed
+to have lost all courage in the face of the new disaster.</p>
+
+<p>"Can't we empty the tanks and rise to the surface?" asked Andy.</p>
+
+<p>"The tanks are not filled," replied Mr. Henderson. "What is taking us
+down is the force of the whirlpool and not the weight of water."</p>
+
+<p>"Then you fear for the worst?" asked Andy.<span class='pagenum'><a name="Page_174" id="Page_174">[174]</a></span></p>
+
+<p>"I do," said the captain simply.</p>
+
+<p>"Don't give up the ship!" exclaimed the old hunter suddenly. "Never say
+die! It's a long lane that has no turns! Hip! Hip! Hurrah!"</p>
+
+<p>They all turned to stare at the old man.</p>
+
+<p>"Never mind," said Mr. Henderson in a soothing tone, that one would use
+toward a baby, or a person not right in their head. "Never mind. We may
+be saved."</p>
+
+<p>"Oh I'm not crazy!" exclaimed Andy. He tried to caper about but the
+motion of the ship made him dizzy and he had to sit down. "I'm all
+right! I just happened to think of something!"</p>
+
+<p>"What is it?" asked the captain eagerly.</p>
+
+<p>"Send the ship ahead!" exclaimed Andy. "Speed her as fast as she will
+go. Try her strength against the force of the whirlpool! We may win!"</p>
+
+<p>"Good!" exclaimed Mr. Henderson. "I was too much depressed to think of
+that! The ship has powerful engines. Queer you should remember that
+instead of me. Come, Washington, start the screw going! We will try to
+beat the whirlpool!"</p>
+
+<p>The submarine was now whirling around so rapidly that it was difficult
+for any one to stand without leaning against the sides or holding on to<span class='pagenum'><a name="Page_175" id="Page_175">[175]</a></span>
+something. It was going lower and lower down, as the gage showed.</p>
+
+<p>Soon a throb that was felt through the length of the craft told that the
+engine had started. The vibration increased until it seemed that the
+ship would be torn apart. Never had the big screw revolved at greater
+speed.</p>
+
+<p>For a while the struggle between the force of man represented by the
+engine, and the power of nature, embodied in the whirlpool, seemed
+equal. Neither could gain the mastery. The ship continued to slide
+around in ever narrowing circles while the big cable of water, forced
+through the tunnel by the screw, was like a cataract.</p>
+
+<p>"Which will win?" asked the professor softly to himself.</p>
+
+<p>He crawled to the gages and watched them. Only by their needles could it
+be told when the battle had turned in favor of the adventurers.</p>
+
+<p>The circular motion, that was now terrible in its speed and power,
+seemed to culminate in a rush that almost overturned the ship. In the
+engine room Washington was laboring to keep the machine at top speed. He
+put on the last ounce of power.</p>
+
+<p>"Hurrah!" yelled the professor suddenly. "I think we shall win!"</p>
+
+<p>He pointed to the depth gage. The needle,<span class='pagenum'><a name="Page_176" id="Page_176">[176]</a></span> which had showed a constantly
+increasing record, until it was now at two hundred feet, had stopped. It
+showed they were going no lower.</p>
+
+<p>Then Mr. Henderson looked at the indicator which showed the progress
+straight ahead. The needle was beginning to tremble. As he watched he
+saw it move, slowly at first, until, as the powerful screw won a victory
+over the terrible whirlpool. The gage marked one, two and then three
+miles an hour.</p>
+
+<p>"We are leaving the swirling waters!" cried Mr. Henderson.</p>
+
+<p>Then, all at once, as though it was an arrow shot from a gigantic bow,
+the <i>Porpoise</i> cleft the under-billows and shot ahead, free at last from
+the grip of the whirlpool.</p>
+
+<p>Man had triumphed over nature!</p>
+
+<p>On rushed the ship like a race horse, for the engine was working as it
+never had before, and it did not have the pool to contend against.</p>
+
+<p>"Slow down," said Mr. Henderson, "and we will go to the surface."</p>
+
+<p>Two minutes later, under the buoyancy of her empty tanks, the <i>Porpoise</i>
+lay floating on the top of the waves, under the shining stars.<span class='pagenum'><a name="Page_177" id="Page_177">[177]</a></span></p>

+<h2>CHAPTER XXII</h2>
+
+<h3>UNDER FIRE</h3>
+
+
+<p>"I shouldn't want to go through that experience again," remarked Mr.
+Henderson, as he, with all of the ship's company except Mrs. Johnson and
+Nellie went on deck. "I thought we were lost, sure."</p>
+
+<p>"Lucky our engine didn't go disproportionatin' herself at de mostess
+criticless moment," put in Washington. "Golly, but she suttinly did
+hum!"</p>
+
+<p>"And you deserve credit for making her do the humming," went on the
+professor with a smile.</p>
+
+<p>"Well, we didn't catch the ghost," remarked Jack, "though I certainly
+saw him, it or her, whatever the thing is. I felt it too."</p>
+
+<p>"It's rather strange," spoke the professor. "Every time, or nearly every
+time the ghost, as I suppose we must call it for the present, makes its
+appearance, something terrible happens to the ship. I hope it doesn't
+show up too often."</p>
+
+<p>It was three o'clock in the morning, and they had battled with the
+whirlpool over two hours.<span class='pagenum'><a name="Page_178" id="Page_178">[178]</a></span> They talked of little else, and each one told
+how he or she felt.</p>
+
+<p>"It was just like twisting yourself up tight in the swing, and then
+letting the rope unwind," said Nellie, and they all agreed that she had
+described the sensation perfectly. They laughed, also, a thing they had
+felt little like doing a short time previous.</p>
+
+<p>The engine had run so hard, and some of the bearings had become so warm,
+that for the rest of the night the professor decided to let the
+machinery remain stationary. This would give it time to cool down he
+said, and they could make up the time lost the next day.</p>
+
+<p>Tired out with the night's worry and labors they all slept late the next
+morning, and it was nearly ten o'clock before breakfast was over. The
+ship was started on her course once more, and Jack, who was steering,
+made the engine hum as the submarine scudded along, submerged about
+fifty feet.</p>
+
+<p>"When you have time I would like to talk to you," said Mrs. Johnson to
+Captain Henderson.</p>
+
+<p>"I'm at your service now," replied the inventor.</p>
+
+<p>"What are you going to do with Nellie and me?" the lady went on.</p>
+
+<p>"Take you to the south pole with us," was the answer, with a smile.<span class='pagenum'><a name="Page_179" id="Page_179">[179]</a></span></p>
+
+<p>"It's very kind of you, and I don't want to put you to any trouble,"
+went on Mrs. Johnson. "But I would like to go back north."</p>
+
+<p>"I'd like to oblige you," returned the inventor, "but I hate to turn
+back now. We are well on our voyage, and I may never get another chance
+to locate the pole. Don't you want to accompany us? Think of the
+glorious achievement!"</p>
+
+<p>"I'd rather go back north," persisted the lady. "But I wouldn't ask you
+to turn the ship around. What I was going to suggest was to sail along
+on the surface for a few days and see if you cannot sight a homeward
+bound steamer or sailing vessel. Then you could put me and Nellie aboard
+her."</p>
+
+<p>"Of course!" exclaimed Mr. Henderson. "I never thought of that. Though
+we will be sorry to lose your company, and that of your little girl, I
+will do anything to oblige you. We will at once go to the surface."</p>
+
+<p>He called the necessary order to Jack through a speaking tube which led
+to the conning tower. In a few minutes the ship shot upward, and emerged
+from the ocean in a little shower of foam and spray.</p>
+
+<p>She lay undulating on the surface, and was just beginning to move
+forward again, under the influence of the screw, when a dull boom echoed
+off to the left.<span class='pagenum'><a name="Page_180" id="Page_180">[180]</a></span></p>
+
+<p>Jack looked from the observation windows in the conning tower and saw,
+about a mile away a big steamer. From her side a white cloud of smoke
+floated, and then the water splashed about fifty feet from the blunt
+nose of the submarine.</p>
+
+<p>Once more came the boom, the white cloud of smoke and this time the
+water splashed only twenty-five feet away from the bow of the
+<i>Porpoise</i>. A third time came the sound, and the splash was even nearer.</p>
+
+<p>"They're firing on us!" yelled Jack.</p>
+
+<p>At his cry the professor ran on deck. He was just in time to see the
+fourth shot made, and this time the shell dropped into the water just
+astern of the <i>Porpoise</i> and so close that when it exploded it sent a
+shower of spray all over the deck.</p>
+
+<p>"Here! Stop that!" yelled Mr. Henderson, shaking his fist in the
+direction of the steamer. "You nearly hit us that time. Do your
+practicing in some other direction!"</p>
+
+<p>"I don't think they can hear you," said Jack. "And besides, I don't
+believe they are practicing."</p>
+
+<p>"Then what in the world are they doing?"</p>
+
+<p>"Shooting at us I guess."</p>
+
+<p>"Why do they want to shoot at us? We haven't done them any damage."</p>
+
+<p>"Perhaps they think we are a torpedo boat," suggested Jack. "Maybe that
+vessel's nation is at<span class='pagenum'><a name="Page_181" id="Page_181">[181]</a></span> war with some other one and wants to sink us if
+it can."</p>
+
+<p>"I believe you're right!" exclaimed Mr. Henderson. "But this will never
+do. They must stop!"</p>
+
+<p>Once more the big gun on the ship was fired and the shell came
+dangerously close. At the same time several other reports, less in
+volume were heard, and the water all about the submarine began to bubble
+as the missiles from the machine guns cut the waves.</p>
+
+<p>"Maybe it's an English vessel sent to capture Mark and me because of
+that anarchist trouble at the hotel," Jack went on.</p>
+
+<p>"Nonsense!" exclaimed the captain. "But whatever it is, we must stop it,
+or they will sink my ship. Wave your handkerchief, Jack."</p>
+
+<p>The boy sprang to the top of the conning tower, in order to permit those
+on the vessel to see him more plainly, and vigorously shook the white
+rag. That it was observed was evident when some one on the steamer
+wig-wagged back a reply. In a few minutes a boat was seen to put off
+from the ship, and soon a little launch, in command of a lieutenant in
+uniform, drew up alongside the <i>Porpoise</i>.</p>
+
+<p>"Who is captain of this craft?" asked the lieutenant as he came aboard.<span class='pagenum'><a name="Page_182" id="Page_182">[182]</a></span></p>
+
+<p>"I am," replied Mr. Henderson. "What do you mean by firing on me?"</p>
+
+<p>"I am Lieutenant Muchmore," said the other, saluting. "Captain Wackford,
+of the <i>Sylph</i>, in His <ins title="Transcriber's Note: original reads 'Britanic'">Britannic</ins> Majesty's service, presents his
+compliments, and asks you to pardon the occurrence. You see we took you
+for a derelict and were trying to sink you."</p>
+
+<p>"I thought perhaps war had broken out between some country and the
+United States since we left port," went on Mr. Henderson, "and that you
+were trying to make a capture."</p>
+
+<p>"No, it was only that we thought you a waterlogged craft, and a danger
+to navigation," repeated the lieutenant. "But what sort of a ship have
+you?"</p>
+
+<p>"Come below and I'll show you the finest submarine that ever was built,"
+answered the inventor with pardonable pride. "If you don't mind, give
+your launch orders to go back to the ship, and I'll <ins title="Transcriber's Note: original reads 'show was something'">show something</ins>
+that will make you open your eyes."</p>
+
+<p>Anxious to see what the strange little craft could do Lieutenant
+Muchmore sent his launch back, and went below with Captain Henderson. He
+was astonished at what he saw, and unlike most Englishmen was willing to
+say so.</p>
+
+<p>Mr. Henderson then went to the conning tower.<span class='pagenum'><a name="Page_183" id="Page_183">[183]</a></span> He directed the man-hole
+cover to be clamped on, and then filled the tanks. The ship sank fifty
+feet below the surface and then shot forward.</p>
+
+<p>Seated in the cabin the lieutenant was observing with wonder showing on
+his face at the accomplishment of sailing along under water. Suddenly
+the lights were shut off, and the shutters moved back from the
+bull's-eye windows. The sea, glowing in the beams of the search light,
+was alive with fish, large and small, beautiful and hideous.</p>
+
+<p>"Wonderful!" exclaimed the Englishman.</p>
+
+<p>The bull's-eyes were closed, the lights switched on, and then, speeding
+the engine almost to the top notch the captain steered the submarine
+straight for the war-ship.</p>
+
+<p>He had carefully noted her direction before starting his own craft, and
+he resolved to do a little man&oelig;uvering that would still further
+astonish the visitor. By careful reading of the different gages Mr.
+Henderson was able to come to the surface right in front of the <i>Sylph</i>,
+to the no small astonishment of the men on the deck of the vessel.</p>
+
+<p>Then, just to show what the <i>Porpoise</i> could do, the inventor darted
+around the war-ship in a circle. He sunk below the surface, went under
+the keel of the <i>Sylph</i> and came up on the other side. Then he went the
+whole length of her, under water, starting at the stern and ending at
+the bow, where<span class='pagenum'><a name="Page_184" id="Page_184">[184]</a></span> he brought the submarine to a rest in a smother of foam.</p>
+
+<p>"Great! Wonderful! Surprising!" were some of the adjectives Lieutenant
+Muchmore used as he stepped from the conning tower, with Captain
+Henderson, onto the deck.</p>
+
+<p>At the appearance of the officer and the inventor a group of those on
+the <i>Sylph</i> gave three cheers for the little vessel.</p>
+
+<p>"Is she for sale?" asked Captain Wackford.</p>
+
+<p>"No, thank you," replied Mr. Henderson with a laugh.</p>
+
+<p>"Because if she is I'll give you free passage to England with her, on my
+ship," went on the commander. "My government would give a fortune for a
+boat that can do what yours does."</p>
+
+<p>"It is not for sale," repeated Mr. Henderson, "but I have some one on
+board who would appreciate a free passage to England, or any northern
+port."</p>
+
+<p>"Who is it?" asked Captain Wackford.</p>
+
+<p>"A Mrs. Johnson and her daughter."<span class='pagenum'><a name="Page_185" id="Page_185">[185]</a></span></p>

+<h2>CHAPTER XXIII</h2>
+
+<h3>CAUGHT IN AN ICE FLOE</h3>
+
+
+<p>Mr. Henderson soon explained the finding of the lady and the little
+girl, and Captain Wackford readily agreed to give them passage to New
+York, as the <i>Sylph</i> was to call at that port.</p>
+
+<p>So Nellie and her mother were put aboard the warship, after bidding
+farewell to the captain and crew of the submarine. Mr. Henderson and the
+boys promised to write to them as soon as they got back from their
+voyage to the south pole, and, amid a chorus of good-byes the <i>Porpoise</i>
+resumed her journey.</p>
+
+<p>For several days the submarine forged to the south, and the weather
+became noticeably cooler. Some of the nights were chilly, and those on
+watch were glad of the heavy coats they had brought along.</p>
+
+<p>One morning, after a week of travel, when no interruptions had occurred
+by reason of accidents, old Andy came up on deck, and sniffing the air,
+said:<span class='pagenum'><a name="Page_186" id="Page_186">[186]</a></span></p>
+
+<p>"We'll sight ice before night, or I'm a Dutchman."</p>
+
+<p>"What makes you think so?" asked Jack.</p>
+
+<p>"I can smell it," replied the hunter, whereat Jack, and Mark who had
+joined him, laughed.</p>
+
+<p>"That is no joke," put in Professor Henderson, who, coming up the
+companionway heard what was said. "Old sea captains will tell you they
+can smell an iceberg long before they can see it."</p>
+
+<p>"I don't claim to be a sea captain," said Andy, "but I once was on a
+whaling voyage and I learned to sniff ice in the air. I saved the ship
+from collision with a berg once."</p>
+
+<p>"Let me see," began the inventor as the adventurers sat about the supper
+table after the meal was finished, "who have the watches on deck
+to-night?"</p>
+
+<p>"Washington first and Bill second," replied Jack looking at the chart.</p>
+
+<p>"Keep a sharp watch for the icebergs," advised the captain. "If you feel
+a sudden chill in the air, and see something white, stop the engine at
+once and call for me."</p>
+
+<p>When the <i>Porpoise</i> had been put in shape for the night, and the
+company, tired out from their labors over a general "house cleaning"
+which Captain Henderson had insisted on, went to bed, Washington took
+his place in the conning tower.<span class='pagenum'><a name="Page_187" id="Page_187">[187]</a></span></p>
+
+<p>It was quite cold, but as the temperature for several days past had been
+steadily falling, nothing was thought of it.</p>
+
+<p>"I guess I'll git out my fur-lined sealskin coat," said the colored man
+to himself as he felt the chill night air, that seemed to increase in
+frigidity along about eleven o'clock. He went to the cabin to get his
+overcoat, and, returning on deck prepared to spend the rest of his hour
+of watch in ease and comfort. He stretched out on the bench in the
+conning tower, noted that the machinery was working right and that the
+proper course was <ins title="Transcriber's Note: original reads 'beeing'">being</ins> steered, and then he let his thoughts drift to
+the many adventures he and his employer had gone through of late, and
+also while on the trip "Through the Air to the North Pole."</p>
+
+<p>Washington gave one <ins title="Transcriber's Note: original reads 'firghtened'">frightened</ins>, startled look, in a few minutes, so
+comfortable had he fixed himself, but happening to look forward through
+the glass-covered porthole of the tower, he saw something that made the
+cold chills run down his back.</p>
+
+<p>There, right in front of the <i>Porpoise</i>, and not a cable-length away was
+a tall, mysterious, white thing which was shimmering in the pale light
+of the moon that had lately risen.</p>
+
+<p>Washington gave one frightened, startled look, and then, with a tongue
+that could hardly move, he yelled out:<span class='pagenum'><a name="Page_188" id="Page_188">[188]</a></span></p>
+
+<p>"De ghost! De ghost! He'll git me suah!"</p>
+
+<p>Then the colored man made a dive for the stairway leading to the cabin,
+but missed it and brought up with a crash on the steel floor of the
+conning tower.</p>
+
+<p>"What is it?" called Professor Henderson, springing out of his bunk.</p>
+
+<p>"De ghost!" wailed Washington from the huddled up heap he was in.</p>
+
+<p>"Catch him!" yelled the captain.</p>
+
+<p>"I dasn't," moaned Washington.</p>
+
+<p>The next instant the ship quivered from stem to stern. There was a
+terrible shock, followed by a grinding, crashing sound. Then the craft
+seemed to be pressed down by some great weight. It heeled over to one
+side, and the water began to pour down the open man-hole.</p>
+
+<p>"Quick! Clamp on the covers!" shouted Mr. Henderson as he felt the sea
+dashing into the interior of the boat.</p>
+
+<p>Jack and Mark sprang to obey. It took all their strength, for the water
+was running in like a mill-race.</p>
+
+<p>"What has happened?" asked Andy, as he tried to climb up the
+companionway ladder, that was tilted backward.</p>
+
+<p>"I guess we've hit your iceberg!" cried Mr. Henderson.<span class='pagenum'><a name="Page_189" id="Page_189">[189]</a></span></p>
+
+<p>"I knew I smelled the frozen stuff," replied the old hunter.</p>
+
+<p>They got the covers on the manhole only just in time and they all
+crowded into the cabin, while Jack switched on the electric lights.</p>
+
+<p>"Is the ship damaged?" asked Mark.</p>
+
+<p>"I think not," replied Mr. Henderson. "But we are sinking. Look at the
+depth gage."</p>
+
+<p>The hand on the clock-face was moving slowly around. From ten it went to
+twenty feet, then to thirty and kept going until it stood at seventy.</p>
+
+<p>"Look to the air tanks," ordered Mr. Henderson to Washington, who, by
+this time had recovered from his fright. "See if they are all right."</p>
+
+<p>The colored man came back in a few minutes and reported that the supply
+of compressed atmosphere was safe and that there was plenty of it.</p>
+
+<p>"That's good," remarked Mr. Henderson. "Whatever else happens we can
+breathe for a while."</p>
+
+<p>"But what has happened?" asked Andy.</p>
+
+<p>"I think the top part of an iceberg toppled down on us," was the reply.
+"You know about nine-tenths of a berg is under water. Sometimes there is
+a warm current of the ocean underneath the ice, and it melts. Then it
+becomes top-heavy and tilts over. One of that sort must have caught us,
+and has shoved us down into the sea."<span class='pagenum'><a name="Page_190" id="Page_190">[190]</a></span></p>
+
+<p>"But why don't we rise again when the ice floe slips off us?" asked
+Mark.</p>
+
+<p>"Because, in all probability the ice will not slip off us," answered the
+professor grimly. "It may be so large that it has caught us like a bug
+under a barn door."</p>
+
+<p>"Then we are fast in the ice under water," spoke Andy after a pause.</p>
+
+<p>"It looks like it," came from the inventor. "However we will not give up
+yet. We may be able to make our way out. Start the engine at full speed,
+Washington."</p>
+
+<p>The machinery which the professor had shut down at the first cry of
+alarm was set going. Soon the throb and hum told that the big screw was
+revolving.</p>
+
+<p>Meanwhile the <i>Porpoise</i> had regained an even keel, and had stopped
+sinking, remaining at the depth of seventy feet below the surface.</p>
+
+<p>"We will first try to go straight ahead," said the captain.</p>
+
+<p>He turned on more power and they all waited in anxiety. The test would
+tell whether they could escape in that direction or not.</p>
+
+<p>But, though the powerful screw churned the water to foam in the tunnel,
+the <i>Porpoise</i> never budged. It was as if she was held in a vice.</p>
+
+<p>"It's of no use," remarked Mr. Henderson with<span class='pagenum'><a name="Page_191" id="Page_191">[191]</a></span> a shake of his head as he
+watched the speed gage and noted that it remained stationary. "We must
+now try the other way."</p>
+
+<p>Once more the big screw was set going, this time in the opposite
+direction, so as to pull the ship out of the ice if it was possible. But
+this, too, was of no avail.</p>
+
+<p>"It looks as if the ice had us," said Andy, trying to speak in a
+cheerful tone. "But there's one way more to try."</p>
+
+<p>"What is that?" asked Mr. Henderson.</p>
+
+<p>"If we were in the air ship we could go up," replied the old hunter.
+"But, as it is, we had better go down. Why don't you fill all the water
+tanks, and try to sink beneath the iceberg? It can't go down so very far
+into the water, and I reckon we could slip under it."</p>
+
+<p>"The very thing!" exclaimed the professor, whose mind was too sorely
+troubled over the happening to enable him to think of plans of escape.
+"That's the best thing to do."</p>
+
+<p>Under the inventor's direction Washington filled the tanks and then, ere
+the pumps had ceased working, the screw was started and the deflecting
+rudder inclined to cause the ship to dive.</p>
+
+<p>One, two, three minutes passed, and still the <i>Porpoise</i> did not move
+toward the bottom of the sea. She remained submerged and stationary.<span class='pagenum'><a name="Page_192" id="Page_192">[192]</a></span>
+Anxious eyes gazed at the dials. The indicating hands trembled under the
+throbbing of the engines, but did not move.</p>
+
+<p>"It will not work!" exclaimed Mr. Henderson in sorrowful tones.</p>
+
+<p>"What does it mean?" asked Bill, who had come up to where the others
+stood.</p>
+
+<p>"It means that we are prisoners in the ice; caught between the upper and
+lower parts of a gigantic berg, and held here under the water."</p>
+
+<p>"Can't we ever get out?" asked Jack, a tremor coming into his voice.
+"Can't we escape when the ice melts?"</p>
+
+<p>"The ice of the southern polar sea seldom melts in this latitude,"
+replied the professor.</p>
+
+<p>An ominous silence <ins title="Transcriber's Note: original reads 'folowed'">followed</ins> his words.<span class='pagenum'><a name="Page_193" id="Page_193">[193]</a></span></p>
+
+

+<h2>CHAPTER XXIV</h2>
+
+<h3>THE SHIP GRAVEYARD</h3>
+
+
+<p>Truly the adventurers were in a position that might well cause the
+stoutest heart to quail. With hundreds of tons of ice above, below, and
+on every side of them, their chances of escaping alive from this frozen
+tomb were very small.</p>
+
+<p>"Can't we make an attempt to get out of this prison?" asked Jack.</p>
+
+<p>"Indeed we will," said the professor. "We will try all the means at our
+command. If they all fail&mdash;"</p>
+
+<p>He dared not finish the sentence, but they all knew what he meant. It
+was now about one o'clock in the morning. The ship had become stationary
+after the uneasy motion caused by the <ins title="Transcriber's Note: original reads 'oscilation'">oscillation</ins> of the big berg.</p>
+
+<p>"We may as well turn in and get a little sleep," remarked Mr. Henderson.
+"We can all work better if we get some rest."</p>
+
+<p>It is doubtful whether any of them slept, for the horror of their
+position was too fresh in their minds. Still, lying down in the bunks
+rested them.<span class='pagenum'><a name="Page_194" id="Page_194">[194]</a></span></p>
+
+<p>It was six o'clock when Washington awoke. In spite of the dangers of the
+icy grave, he had managed to get a little sleep. He prepared breakfast
+and called the others.</p>
+
+<p>"Make a good meal," advised Mr. Henderson. "We have plenty of work ahead
+of us."</p>
+
+<p>"Are you going to free the ship?" asked Mark.</p>
+
+<p>"I am going to try," was the answer.</p>
+
+<p>A little later the inventor was busy in one of the small store rooms aft
+when Jack came up. The professor was carefully taking out a box
+labelled:</p>
+
+<div class='center'>
+<big>DYNAMITE! DANGEROUS!</big><br />
+</div>
+
+<p>"What are you going to do?" asked the boy.</p>
+
+<p>"I am going to try the same experiment we attempted on the volcanic
+island," was the reply. "Only, this time, I am afraid we shall have to
+complete it to the end. There is little likelihood of the ice falling
+apart."</p>
+
+<p>"Then you are going to blow it up?" went on Jack.</p>
+
+<p>"That's what I hope to do," the inventor went on. "I see no other way,
+and, though there is a risk, it is not so great a one as to wait to be
+crushed in the ice as it freezes more solidly."</p>
+
+<p>Under the directions of Mr. Henderson they got out the diving suits. The
+professor, the two boys<span class='pagenum'><a name="Page_195" id="Page_195">[195]</a></span> and Andy put them on. The dynamite, in
+specially <ins title="Transcriber's Note: original reads 'preparel'">prepared</ins> water-proof packages, with long fuses was laid in
+readiness close to the door of the diving chamber.</p>
+
+<p>Into the cell, the four who were to make the perilous journey under the
+ice, took their places. The water was slowly admitted, and then, with
+the electric lights in their helmets throwing out powerful gleams, they
+started forward as the outer door swung open.</p>
+
+<p>It was well they had all taken the precautions to don thick
+undergarments and clothing, for, even through the heavy rubber diving
+suits, the terrible cold of the southern polar sea struck a chill to
+their very bones.</p>
+
+<p>As the professor had said, the ship was caught between the upper and
+lower parts of the iceberg. On either side, ahead and to the rear there
+was open water. Beneath their feet there was a floor of ice. It was as
+if they and the ship had been placed between two great sheets of the
+frozen matter.</p>
+
+<p>Their progress was slow, for the water hampered their movements and each
+one had some of the dynamite to carry. The footing, too, was insecure,
+for the icy bed of the ocean was slippery.</p>
+
+<p>As they were huddled together, the professor in the lead, and their
+lamps making a faint illum<span class='pagenum'><a name="Page_196" id="Page_196">[196]</a></span>ination in the darkness, they suddenly became
+aware of a great shadow over them. They looked up, and their hearts
+nearly ceased beating as they saw a gigantic sperm whale right over
+them, and between the ice. The terrible animal had observed them also,
+and, food being scarce in those frigid regions, had evidently made up
+its mind to dine on some choice morsels.</p>
+
+<p>The whale was nearly as large again as the submarine, and to the
+frightened voyagers seemed more immense than a house. With slow motions
+of the flukes the animal placed itself right over the boys and men,
+ready to rush at and take them into its terrible maw.</p>
+
+<p>Old Andy, who alone seemed to retain his presence of mind, stepped to
+the front. The professor and the boys wondered what he was going to do.
+Then Andy held up one of the electric guns.</p>
+
+<p>Always thinking of his chosen calling, the old hunter had picked up the
+weapon as he was leaving the <i>Porpoise</i>. He waited until the whale was
+within a short distance, so close in fact that the small eyes, out of
+all seeming proportion to the rest of the big body, could be seen. Then
+Andy fired one of the explosive bullets straight into the open mouth
+that was fringed with rows of the springy bone that is a part of a
+whale's eating apparatus.<span class='pagenum'><a name="Page_197" id="Page_197">[197]</a></span></p>
+
+<p>The shot took effect, and made a vital wound. In its death struggles the
+beast lashed the ocean to foam, and, but for the fact that Andy as soon
+as he fired the shot crouched down, pulling the others toward the floor
+of ice, they might all have been killed.</p>
+
+<p>The whale turned and made a rush in the opposite direction to that of
+the divers. This was a welcome sign to the professor, for he knew the
+animal was seeking open water and this told him it must be somewhere in
+the vicinity.</p>
+
+<p>Their hearts still beating loudly from the closeness of death, the
+adventurers continued their way. On every side were fish, big and
+little, and, though some of the larger ones thrust themselves to the men
+and boys, as if wondering what strange creatures they were, none of them
+offered to attack.</p>
+
+<p>Led by the professor they made a complete circuit of the ship that was
+held fast in the ice. As the inventor had surmised, the <i>Porpoise</i> was
+nipped only above and below. If she could be freed at either of those
+points she could rise to the surface, or sink down under the ice.</p>
+
+<p>After making a careful examination of the position of the craft, Mr.
+Henderson motioned to have the dynamite placed on the ice, in front of,
+and about two hundred feet away from the nose of the ship.<span class='pagenum'><a name="Page_198" id="Page_198">[198]</a></span></p>
+
+<p>He connected the cartridges with the fuse and wires that were to explode
+them, and then, taking the free end, he started back toward the ship.
+Washington was on the watch for them, and operated the diving chamber.
+Soon the four were back in the <i>Porpoise</i>.</p>
+
+<p>"Now to see if our plan will work," said Mr. Henderson. "I am relying on
+the well known downward force of dynamite to blow a hole in the bottom
+part of the ice, so that we can drop below."</p>
+
+<p>"Why not make a hole above so we can rise and escape?" asked Bill.</p>
+
+<p>"Because," replied the professor, "we are now in the region of perpetual
+ice. The ocean above us is one fast floe, or a number of smaller ones,
+so that, in any event our progress would be impossible. But we can sail
+far enough down under water to escape all the ice. That is the purpose
+of the <i>Porpoise</i>. That is why I built her. We will now begin on the
+last part of our voyage; that is if we can get free of the fearful grip
+of this sea of ice."</p>
+
+<p>There was little they could do to protect themselves. They would either
+escape or be blown to pieces in case the explosive exerted too great a
+force. They all put on life preservers to guard against the contingency
+of the <i>Porpoise</i> being ripped apart and themselves cast into the water,
+yet<span class='pagenum'><a name="Page_199" id="Page_199">[199]</a></span> they realized that without their ship, they could live but a little
+while in the ice-filled water near the south pole.</p>
+
+<p>The professor saw that everything was in readiness. He hesitated a
+moment and looked at the electric button in his hand, for this time the
+dynamite was to be detonated by a battery. How much might depend on one
+push of the finger!</p>

+<span class="caption">THEY WERE IN THE MIDST OF A GRAVEYARD OF WRECKED SHIPS.&mdash;Page 200.</span>
+</div>
+
+<p>There was a slight movement to the muscles of the professor's hand. Then
+it seemed as if a thunderbolt had fallen into the midst of the ocean
+about them.</p>
+
+<p>There was a dull rumble, but the confined space and the thick walls of
+the ship shut most of it out. It was followed by a sickening dizzy
+motion to the submarine. She seemed about to roll over and those in her
+grabbed frantically at the sides. The next instant the craft plunged
+down, down, down, into the water which was filled with broken cakes of
+ice, that rattled against the steel sides, like peas in a pan.</p>
+
+<p>Down and down the <i>Porpoise</i> went, for her tanks were full. More and
+more rapidly she continued to sink, until it seemed she would fetch up
+in the deepest cavern of the ocean.</p>
+
+<p>"We's gwine t' Mars Davy Jones's locker, suah!" Washington exclaimed as
+he looked at the depth gages.<span class='pagenum'><a name="Page_200" id="Page_200">[200]</a></span></p>
+
+
+
+<p>"Has the experiment succeeded?" asked Andy of Mr. Henderson.</p>
+
+<p>"I think so," was the answer. "At any rate we are free from the ice,
+temporarily at least. We are sinking down through the hole the dynamite
+made, just as I hoped we would."</p>
+
+<p>"Where will we end up?" asked Jack.</p>
+
+<p>"No one knows," replied the captain. "But I would say&mdash;"</p>
+
+<p>At that instant the ship stopped sinking and brought up with a bump.</p>
+
+<p>"I should say we were at the end of this part of our journey," finished
+the inventor.</p>
+
+<p>He turned off the cabin lights and lighted the search lamps that threw a
+gleam so the water could be looked at from the bull's-eyes windows. The
+sight that met their gaze was an astonishing one.</p>
+
+<p>They were in the midst of a graveyard of wrecked ships, and, on every
+side, scattered over the ocean bed, were the broken hulks that had once
+been stately vessels.<span class='pagenum'><a name="Page_201" id="Page_201">[201]</a></span></p>

+<h2>CHAPTER XXV</h2>
+
+<h3>CAUGHT BY SEA SUCKERS</h3>
+
+
+<p>"What sort of a place is this?" asked Andy, as he gazed at the last
+resting spot of the big ships.</p>
+
+<p>"They have probably drifted here with the ocean currents, become caught
+in the ice and have remained here hundreds of years," said Mr.
+Henderson. "Some of the ships are very old, and, by their build must
+have sailed the waters centuries ago."</p>
+
+<p>"Maybe some of them are treasure ships," suggested Jack.</p>
+
+<p>"They might be," admitted the professor.</p>
+
+<p>"Then we'll go aboard and get the gold," spoke Mark.</p>
+
+<p>"I'm afraid you'll be disappointed," went on the inventor. "In the first
+place most treasure ships are looted before they sink. And it would be
+very dangerous for any of us to venture to explore those hulks."</p>
+
+<p>"Why?" asked Jack.</p>
+
+<p>"Because they are rotten, and liable to fall to<span class='pagenum'><a name="Page_202" id="Page_202">[202]</a></span> pieces any minute. If
+you happened to be in one at the time you would be caught in the
+wreckage and eventually drowned even though you had on a diving suit.
+Then, again, the ice here is constantly shifting about, and a sudden
+motion of the under-water floe might carry you hundreds of miles away.
+So we will not try to hunt for any fortunes on the sunken ships."</p>
+
+<p>With this the boys were forced to be content. They stood at the small
+windows looking at the skeletons of ships that lay on every side of the
+<i>Porpoise</i>. Some of the craft were big steamers, and others were small
+sailing vessels. A few had jagged holes in the hulls, showing how they
+had been damaged. A few stood upright, with sails all set, as if
+disaster had suddenly come upon them.</p>
+
+<p>"Well, what is the next move?" asked Andy after a pause. "Are we going
+to stay here?"</p>
+
+<p>"We are going to find the South Pole," spoke Mr. Henderson suddenly.
+"That is what I set out to do, and I am going to accomplish it if
+possible. We have had many accidents and a harder time in some respects
+than when we made our trip to the north in the air ship. But I am sure
+we shall succeed. Start the ship to the south, Washington."</p>
+
+<p>"But we may run into an iceberg," objected the old hunter, who was
+inclined to be cautious.<span class='pagenum'><a name="Page_203" id="Page_203">[203]</a></span></p>
+
+<p>"I think not," answered Mr. Henderson. "I believe we are on a sort of
+level plane between two vast upper and lower fields of ice. We can go
+freely in any direction excepting up or down."</p>
+
+<p>"How is that?" asked Mark. "I don't quite understand."</p>
+
+<p>"Because there is, I believe, a big sheet of ice above us, one, say
+several hundred feet thick. The same thing is below us, between us and
+the real bed of the ocean."</p>
+
+<p>"But suppose we have to go up to renew our air supply?" asked Jack.</p>
+
+<p>"We can't go," replied the inventor.</p>
+
+<p>"Then we will die."</p>
+
+<p>"Not necessarily. We will steam along until we come to a place where
+there is no ice above us."</p>
+
+<p>"But I thought you said there was nothing but ice above us now."</p>
+
+<p>"So there is, but I intend to head due south and there, I believe, we
+will find an open polar sea. If we do my theory will be proved and we
+will have made a great discovery."</p>
+
+<p>"Forward then!" exclaimed Jack. "Let us strike for the open sea."</p>
+
+<p>The <i>Porpoise</i> began to move ahead. She steamed slowly, for Mr.
+Henderson realized that he was in dangerous waters. He took his position
+in the conning tower, and had Jack with him to<span class='pagenum'><a name="Page_204" id="Page_204">[204]</a></span> assist in looking for
+any obstructions that they might unexpectedly meet.</p>
+
+<p>The big searchlight gave a fine illumination, for the ice above and
+below reflected back the beams, and what would otherwise have been a sea
+of darkness was made one of daylight.</p>
+
+<p>The water swarmed with fish, but they were like none that the
+adventurers had ever seen or dreamed of before. There were monsters with
+hideous heads, and eyes so large that they occupied nearly half of the
+ugly bodies.</p>
+
+<p>Then there were serpent-like forms, fish with long slender bodies and
+whip-fashioned tails, with jaws that extended before them for ten feet
+or more. Others there were, great lumbering monsters that crawled along
+on the ice, somewhat as seals do.</p>
+
+<p>After several hours' travel the submarine ran into a school of fish that
+had shapes like those of polar bears, while their heads were like those
+of sharks. The creatures swarmed up to the side of the vessel, and some
+scratched with their claw-like fins on the glass windows of the conning
+tower and the side bull's-eyes.</p>
+
+<p>A meal was prepared by Washington, and all the adventurers brought good
+appetites to the table. On and on rushed the ship, every hour coming
+nearer and nearer to the pole.<span class='pagenum'><a name="Page_205" id="Page_205">[205]</a></span></p>
+
+<p>Professor Henderson had turned the steering of the craft over to Mark,
+who, with Jack as an assistant was sending her along at a good speed,
+when suddenly the submarine seemed to slacken in her progress.</p>
+
+<p>"What's the matter now I wonder?" asked Mark.</p>
+
+<p>"Maybe the engine bearings got hot, and Washington had to slow up to
+cool them," suggested Jack.</p>
+
+<p>He looked through one of the side windows in the conning tower, a moment
+later, and uttered a cry of fear.</p>
+
+<p>"What is it?" asked Mark.</p>
+
+<p>Jack pointed with a hand that trembled from fright. Staring at them
+through the thick glass of the bull's-eye the boys beheld the most
+hideous sea monster they had yet encountered.</p>
+
+<p>It seemed to be a vast circular mass of flesh, twenty feet in diameter,
+and, in the middle were two openings each three feet across. They were
+like big holes, and, at the farther end of them could be seen two
+unblinking eyes. In the centre was a horrible mouth, armed with a triple
+row of teeth.</p>
+
+<p>Down below there was a short body, at the end of which was a smaller
+disk, armed with a sharp horny point.<span class='pagenum'><a name="Page_206" id="Page_206">[206]</a></span></p>
+
+<p>"What is it?" asked Jack in a whisper.</p>
+
+<p>"I don't know," replied Mark.</p>
+
+<p>A moment later Mr. Henderson came up the companionway into the tower. He
+caught one glimpse of the monster.</p>
+
+<p>"It is the great sucker of the polar seas!" he exclaimed. "Quick! Speed
+up the engine! If that one, and the mates of it, fasten on to us we will
+have trouble!"</p>
+
+<p>He pressed the signal that connected with the engine room, and told
+Washington to start the engine at its greatest power. The next instant
+the ship throbbed and trembled under the vibrations of the big screw.</p>
+
+<p>"We may escape!" cried the professor.</p>
+
+<p>As he spoke the ship seemed to come to a sudden stop. The engine could
+still be felt moving, and the big screw still churned the water to foam
+in the tunnel, but the craft was stationary.</p>
+
+<p>"We are caught!" exclaimed the professor.</p>
+
+<p>"So we are!"</p>
+
+<p>The windows in the conning tower were darkened. The big sucker had
+thrown itself forward and spread itself over the glass, clasping its
+horrible form half way about the submarine.</p>
+
+<p>"Let's look at the other windows! There may be only one of the
+creatures!" Mr. Henderson exclaimed, as he hurried down the companion
+way<span class='pagenum'><a name="Page_207" id="Page_207">[207]</a></span> and into the main cabin. He threw back the slides covering the
+glass.</p>
+
+<p>The sight that met his eyes caused him to recoil in horror. There,
+pressing their shapes against the steel sides, and over the bull's-eyes
+of the ship were two more of the gigantic suckers!</p>
+
+<p>The ship had now ceased to move, and Washington, in the engine room,
+feeling that something was wrong, had shut off the power. The
+adventurers were caught in a trap more terrible than that of the ice,
+the volcanic mountain, or the Sargasso Sea. It was a trap from which
+they might never escape.</p>
+
+<p>The suckers, thinking the submarine was perhaps a species of fish, like
+themselves, and one of their enemies, had fastened on it their fatal
+vice-like grip. To move through the water, with the weight of all that
+clinging flesh was <ins title="Transcriber's Note: original reads 'impossile'">impossible</ins>.</p>
+
+<p>"What sort of creatures are they?" asked Jack, speaking in a whisper, so
+great was the terror inspired by the presence of the gigantic sea
+suckers.</p>
+
+<p>"I never saw any of them before," replied the professor, "but I have
+read about them. They live only in the polar regions and are a species
+of octupus, only more terrible. Their powers of suction are enormous,
+and once they fasten on a fish or animal they never let go until they
+have<span class='pagenum'><a name="Page_208" id="Page_208">[208]</a></span> absorbed it completely. They act in the same way that a star fish
+does on an oyster."</p>
+
+<p>"But they can't eat the ship," said Jack.</p>
+
+<p>"No, I fancy the steel and iron sides will prevent them from making a
+meal of us."</p>
+
+<p>"Then where is the danger?"</p>
+
+<p>"They will not let go until they discover that they cannot devour us,
+and it may take days. We can only remain under water a comparatively
+short time at the most. So you see where the danger is."</p>
+
+<p>"But can't we go out and kill them? Then they would let go."</p>
+
+<p>"It would be most risky to venture out, protected even with a diving
+suit, and carrying the electric guns," the professor went on. "No, I
+must think of some other plan to free ourselves from the creatures."</p>
+
+<p>"Blow 'em up wif dynamite an' send 'em inter disproportionately
+contrastedable circumferences!" exclaimed Washington, who had been
+listening to the conversation.</p>
+
+<p>"This isn't any time to joke," Mr. Henderson said sternly.</p>
+
+<p>"I wasn't joking," replied the colored man. "Can't we squirt acid on 'em
+or chop 'em up, or&mdash;or&mdash;"</p>
+
+<p>"We can do nothing for the time being," said<span class='pagenum'><a name="Page_209" id="Page_209">[209]</a></span> the professor. "Come, we
+will have a consultation on the subject. Perhaps some one may be able to
+think of a plan of rescue."</p>
+
+<p>"Let us hope so."</p>
+
+<p>They all gathered in the cabin. The professor explained the nature of
+the creatures, as far as he knew them from what he had read or heard. He
+pointed out, through the glass windows, over which the suckers were
+still clinging, how they maintained their grip, by exhausting, through
+their big mouths, the air between their saucer-like surfaces and the
+ship to which they were clinging.</p>
+
+<p>"Can't we go out and fight 'em?" asked Andy, who was always ready to use
+a gun.</p>
+
+<p>"I doubt if we could get out," replied the professor. "Though we can not
+see them, I believe the creatures cover every part of the ship from stem
+to stern. We could never open the door of the diving chamber with that
+terrible sucker covering the iron portal."</p>
+
+<p>"Maybe if we wait long enough a lot of sharks will come along and eat
+'em up," put in Jack.</p>
+
+<p>"I am afraid sharks will not come to these frozen waters," said the
+professor. "They like a warm climate."</p>
+
+<p>"And you don't think it would be feasible to use dynamite," asked Mark.</p>
+
+<p>"We can't get out to place it where it would<span class='pagenum'><a name="Page_210" id="Page_210">[210]</a></span> blow up the fish and not
+us," answered Mr. Henderson. "If we could it might serve."</p>
+
+<p>A silence fell on the group. They were in sore straits and there seemed
+no hope of rescue. The big disk-like bodies that covered the windows did
+not move, but remained there, staring with horrible persistency into the
+interior of the ship.<span class='pagenum'><a name="Page_211" id="Page_211">[211]</a></span></p>
+

+
+<hr style="width: 65%;" />
+<h2>CHAPTER XXVI</h2>
+
+<h3>LAND UNDER ICE</h3>
+
+
+<p>Suddenly the craft began to move. Slowly at first, then, with more speed
+it forged ahead through the water.</p>
+
+<p>"Are we free?" asked Andy, starting up.</p>
+
+<p>"Who started the machinery?" demanded the professor.</p>
+
+<p>"No one," replied Jack. "We are all here. There is no one in the engine
+room."</p>
+
+<p>"But we are moving," said Mark.</p>
+
+<p>"It's dem sucker-fish!" exclaimed Washington. "Dey is takin' us off to
+der dens an' dere we'll all be eat up!"</p>
+
+<p>"I'm afraid part of it is true," said Mr. Henderson. "The creatures are
+certainly making off with us. How powerful they must be!"</p>
+
+<p>"Will dey take us to a cave?" faltered Washington. "Will dey eat us up?"</p>
+
+<p>"I don't think they'll eat us up," spoke the inventor. "It would defy
+even their powerful sucking apparatus to bore through the steel sides of
+the <i>Porpoise</i>. What I am afraid of is that<span class='pagenum'><a name="Page_212" id="Page_212">[212]</a></span> they may move us to some
+hidden depth where we will be caught under the rocks or in the ice, and
+so lose what little chance there is of getting free."</p>
+
+<p>"And the worst of it is we can't do a thing to help ourselves!"
+exclaimed Andy. "This is the worst game I was ever up against!"</p>
+
+<p>The adventurers were indeed helpless. They could not get out of their
+ship to attack the monsters, even had they dared to. Their engine,
+powerful as it was, had proved no match for the creatures, and now they
+were being carried away, ship and all, to some unknown place.</p>
+
+<p>The ship did not go through the water fast. Though the suckers seemed to
+be working in union their bodies were too unwieldly, and the ship so
+large, that their pace was slow. Nevertheless they kept steadily on.</p>
+
+<p>Several times, in their desperation, the adventurers tried the force of
+the big screw against that of the suckers. It was of no avail. Neither
+was the device of emptying the tanks, and trying to force the craft up
+as far as the roof of ice would permit it to go.</p>
+
+<p>"It's of no use," announced Mr. Henderson with something that sounded
+like a groan. "We must prepare for the worst."</p>
+
+<p>"How long can we live here without going to<span class='pagenum'><a name="Page_213" id="Page_213">[213]</a></span> the surface after a fresh
+supply of air?" asked Bill.</p>
+
+<p>"About three days," was the answer. "I took the precaution to put a
+double supply into the tanks, in readiness for an emergency, but I never
+thought of such a terrible situation as this."</p>
+
+<p>The submarine seemed to be moving more rapidly now. It was useless to
+try to see through either the windows in the side or in the conning
+tower, for all the glass was covered by the horrible bodies.</p>
+
+<p>"What will they do with us when they get us where they want us?" asked
+Andy.</p>
+
+<p>"What can they do except hold us prisoners until&mdash;until&mdash;" The professor
+broke off the sentence he dared not finish.</p>
+
+<p>For an hour or more the craft was moved through the water at moderate
+speed. Then it came to a stop. Those on board were alert for what might
+happen next.</p>
+
+<p>"I guess dey done got us in der cave," said Washington with chattering
+teeth. "Now dey'll begin to devour us wid dem terrible big mouths!
+Golly, I wish I was home!"</p>
+
+<p>"Stop that nonsense!" exclaimed Mr. Henderson. "Be a man! There is no
+danger yet. The sides of the <i>Porpoise</i> will defy worse enemies than
+those attacking us!"<span class='pagenum'><a name="Page_214" id="Page_214">[214]</a></span></p>
+
+<p>At that instant the ship began to move again. It was hauled slowly
+through the water.</p>
+
+<p>"They are pulling us backward!" said Andy, as he watched the needle of
+the compass.</p>
+
+<p>Once more the submarine was stopped. Then it moved forward at a more
+rapid pace than at any time since the suckers had seized it. An instant
+later it brought up against some solid object with such a jar that those
+inside were thrown off their feet.</p>
+
+<p>"Something has hit us!" cried Jack.</p>
+
+<p>"More likely we've struck something," said the professor.</p>
+
+<p>Again the ship forged to the rear, and once again it was sent swiftly
+ahead. Then came the second shock, harder than the first, which sent
+some of the party headlong.</p>
+
+<p>"They are banging us against a rock!" cried Mr. Henderson.</p>
+
+<p>"Do you mean those sea suckers?"</p>
+
+<p>"Yes. They have probably found that the shell of the <i>Porpoise</i> is too
+hard even for their powerful jaws. So they have taken us to some place
+where the rocks show and are banging us against them in order to break
+the ship, so they can get at what is inside."</p>
+
+<p>Once more the ship was drawn backward and again dashed against the
+stone. The shock was a<span class='pagenum'><a name="Page_215" id="Page_215">[215]</a></span> hard one and toppled over all who were not
+clinging to something.</p>
+
+<p>"They are ramming us bow on against the rocks," cried Andy. "It will
+break us apart if they hit us many more times!"</p>
+
+<p>Washington hurried forward. He came back with his eyes showing terror.</p>
+
+<p>"There's a lot of rocks right ahead ob us!" he exclaimed. "I see 'em
+through th' little window jest above th' screw. There's land under this
+here water!"</p>
+
+<p>"Land under this ice do you mean?" asked the professor.</p>
+
+<p>"That's what I mean, an' we's bein' rammed agin th' rocks!"</p>
+
+<p>"There it goes again!" cried Jack, as the ship shivered from stem to
+stern against the impact of the blow.</p>
+
+<p>"This can not last long," said Mr. Henderson. "If they strike us many
+more times some of the places will start, the water will come in, and we
+will drown!"</p>
+
+<p>"But what can we do?" asked Jack.</p>
+
+<p>"Let's go out now and see if we can't kill some of the beasts with the
+guns," suggested Andy.</p>
+
+<p>"I cannot permit it," answered the inventor. "Our position is bad enough
+as it is, but to go out would be to lose our lives for a certainty. The<span class='pagenum'><a name="Page_216" id="Page_216">[216]</a></span>
+suckers would swallow us up in a moment. I must find some other way."</p>
+
+<p>There was a period of silence, while all waited anxiously for what was
+to happen next. It was not long in coming. The next impact of the ship
+against the rocks was the hardest yet, and it seemed that more of the
+suckers must have gripped the craft.</p>
+
+<p>"She's leakin' a little!" exclaimed Washington coming back from an
+inspection forward. "De water am tricklin' in!"</p>
+
+<p>"We must fight them!" exclaimed Andy. He ran to get a gun and his diving
+suit.</p>
+
+<p>"Don't try to go out!" warned the professor. "You will surely be
+killed."</p>
+
+<p>"I'd rather be killed out there than die shut up in the ship!" cried the
+old hunter. "I'm going out!"</p>
+
+<p>"Wait!" exclaimed Jack suddenly. "I have a plan that may save us!"</p>
+
+<p>"What is it? Speak quickly!" said Mr. Henderson. "We are in desperate
+straits!"</p>
+
+<p>As he spoke there came another crash against the rocks.</p>
+
+<p>"We must electrocute the suckers!" cried the boy.</p>
+
+<p>"Electrocute them? What do you mean?"</p>
+
+<p>"Take the wires from the electric light circuit,<span class='pagenum'><a name="Page_217" id="Page_217">[217]</a></span> attach one to each end
+of the ship, and start the dynamo at full speed!" answered Jack.</p>
+
+<p>"What good will that do?"</p>
+
+<p>"The ship is steel," went on the boy. "It will become charged with a
+powerful current. We can insulate ourselves by putting on rubber boots,
+but the shock of the electricity will kill the creatures!"</p>
+
+<p>"Good for you!" exclaimed Mr. Henderson. "Quick boys, everybody lend a
+hand! Washington, detach the wires and run one to the bow and the other
+to the stern of the ship. Then get out the boots."</p>
+
+<p>In a few minutes the dynamo was ready to send a death-dealing current
+through the entire ship. The professor and all the others put on the
+boots, that were a part of the diving equipment. The dynamo was started
+at full speed and the purring hum told that electricity of great power
+was being developed.</p>
+
+<p>The professor stood with his hand on a switch, ready to close the
+circuit as soon as sufficient power had accumulated. Once more the
+suckers backed the ship in order to give it impetus for another impact
+on the stones.</p>
+
+<p>Click! The professor snapped the switch shut. There was a burst of
+bluish-green flame, and the movement of the boat suddenly ceased.<span class='pagenum'><a name="Page_218" id="Page_218">[218]</a></span></p>
+
+<p>"I guess that does for 'em!" shouted Andy.</p>
+
+<p>"Wait a few minutes," advised the professor. "The suckers may not all be
+dead yet!"</p>
+
+<p>He kept the current flowing throughout the length of the ship for
+several minutes, and then turned it off.</p>
+
+<p>"Now to see if the plan worked," he said. The windows in the cabin were
+eagerly scanned.</p>
+
+<p>"Hurrah!" cried Mark. "The suckers have gone!"</p>
+
+<p>"I guess the electricity killed them," spoke Mr. Henderson. "We will
+venture out now in our diving suits and see what sort of a place we are
+in."</p>
+
+<p>Soon the adventurers were arrayed in the heavy suits. Under them they
+wore thick clothing, and in each suit was placed a small flat heater,
+operated by a storage battery. The heaters were made of coils of fine
+wires, and the electric current, meeting with much resistance in passing
+through them, heated the coils, so there was considerable warmth.</p>
+
+<p>It was all needed as they found when they felt the water entering the
+diving chamber, for the fluid was as cold as an ocean full of icebergs
+could make it. Protected however by the heavy suits, warm clothing and
+the heaters the divers were fairly comfortable.</p>
+
+<p>The outer door was opened and they all started<span class='pagenum'><a name="Page_219" id="Page_219">[219]</a></span> back in amazement at the
+sight which met their eyes. Before them lay a forest of real trees, with
+bushes growing among them, while the ground, instead of being like the
+usual ocean bed was covered with grass.</p>
+
+<p>As Washington had said, on getting a small view of the place from the
+little window, it was real land under water.</p>
+
+<p>Their first surprise at the strange spectacle over, the adventurers
+glanced about for a sight of the terrible sea suckers. But they need not
+have feared. Lying in a huddled up mass toward the rear of the
+<i>Porpoise</i> were the dead bodies of the ugly creatures. The electricity
+had finished them.<span class='pagenum'><a name="Page_220" id="Page_220">[220]</a></span></p>

+<h2>CHAPTER XXVII</h2>
+
+<h3>ATTACKED BY AN OCTUPUS</h3>
+
+
+<p>They walked some distance away from the ship, for the land under the
+water was easy to travel on. It looked exactly as if some beautiful
+valley had suddenly been submerged in the middle of summer, when
+everything was fresh and green.</p>
+
+<p>They had gone perhaps a quarter of a mile from the <i>Porpoise</i> when
+Professor Henderson motioned to them that they had better return. On
+their way back they passed what looked to be a large cave in the side of
+a hill. Wondering what could be in it, Mark and Jack paused to peer into
+the black opening.</p>
+
+<p>The next instant two long white things, like slender serpents shot out.
+With the rapidity of lightning they wrapped themselves, one about each
+boy, and, before the horrified companions of the lads could do anything
+the unfortunate youths were whisked out of sight into the cavern.</p>
+
+<p>For a few seconds no one knew what to do. To rush in to the rescue of
+the boys would have been foolhardy, as the terrible octupus, which they
+knew<span class='pagenum'><a name="Page_221" id="Page_221">[221]</a></span> had grabbed the lads, would have been a match for all of the
+adventurers, unarmed as they were.</p>
+
+<p>It would be necessary to return to the ship and come back with some of
+the electric guns, which they had neglected to bring with them. In the
+meanwhile the beast might, and probably would, kill Mark and Jack. But
+there was nothing else to do.</p>
+
+<p>The professor motioned for Andy to remain on the watch at the mouth of
+the cavern, so as to be on hand in case he could help the boys, while
+the others were hurrying toward the ship. Then, leading the way, the
+Professor signalled for Tom and Bill to follow him.</p>
+
+<p>They could not hurry much for the heavy suits and the resistance of the
+water impeded their progress. But they made all the speed they could,
+urged on by a terrible fear.</p>
+
+<p>Meanwhile old Andy stood in front of the cave, hoping against hope that
+there might be some way of aiding the boys. If it had happened above
+water he would not have hesitated to rush in and give battle to the
+beast, even though he was unarmed. If he had his knife now he would
+venture in, at the risk of his life.</p>
+
+<p>"Oh, why didn't I bring my gun along!" thought Andy regretfully.</p>
+
+<p>His hand dropped to his side and his fingers<span class='pagenum'><a name="Page_222" id="Page_222">[222]</a></span> came in contact with a big
+knife in the belt of the diving suit. Here was a weapon he had forgotten
+all about.</p>
+
+<p>He drew forth the blade. It seemed a small one with which to attack so
+large and terrible a creature as the octupus. Yet to remain there,
+knowing the boys were being killed was more than old Andy could stand.
+Grasping the handle with a firm grip he started toward the cave. His
+foot caught in something, and he nearly fell.</p>
+
+<p>Looking down to see what had tripped him he saw a long thin pole,
+straight as a lance. It had once been a tree limb, but all the branches
+were stripped off.</p>
+
+<p>"Now if I only had an iron point for that," Andy thought. Then he
+recollected the knife in his hand.</p>
+
+<p>"The very thing," he remarked aloud, the words sounding startlingly loud
+in the confinement of the copper helmet. "If I only had something to
+fasten the knife on the pole I could make a spear to attack the
+octupus."</p>
+
+<p>Then he saw long streamers of sea weed growing up from the ocean bed.
+They were very tough, a kind of wirey grass that was as strong as rope.
+Andy cut several streamers and, with a hunter's skill bound the knife to
+the end of the staff.<span class='pagenum'><a name="Page_223" id="Page_223">[223]</a></span></p>
+
+<p>Now he had a weapon formidable enough to venture in and give battle to
+the monster. He hesitated no longer, fearing that even the short delay
+might have been too much and that the boys were dead. He entered the
+cave. At first he could perceive nothing for it was quite dark. Then, as
+his eyes became used to the gloom, which the lamp in his helmet faintly
+illuminated, he saw, far back in the rear, the horrible octupus.</p>
+
+<p>Two dark objects, around which were wrapped several folds of the
+terrible arms, Andy guessed to be Mark and Jack, and when he was a faint
+glow coming from them he was sure they were the boys, the gleams coming
+from the lamps in their helmets.</p>
+
+<p>Warily the hunter approached the creature. If he had hoped to take it
+unawares he was disappointed, for, when he had come within ten feet,
+holding his improvised lance outstretched ready for a deadly thrust, the
+creature shot out two long arms toward Andy.</p>
+
+<p>Now the battle began. The snake-like feelers, armed with big saucer
+shaped suckers, lashed about in the water, seeking to clasp the hunter
+in their deadly embrace. But Andy, who had fought many kinds of wild
+animals on land, did not lose his presence of mind in confronting this
+beast of the sea.<span class='pagenum'><a name="Page_224" id="Page_224">[224]</a></span></p>
+
+<p>Nimbly, in spite of the handicap of the heavy diving suit, Andy dodged
+the arms. Watching his chance he thrust at one, and the sharp knife
+severed the end. But another arm shot out, while the wounded one was
+drawn in, and the battle was as much against the old hunter as before.</p>
+
+<p>Once more he thrust his lance, and this time he severed one of the arms
+close to the ugly body. The creature, in its rage and pain, redoubled
+its efforts to clasp Andy.</p>
+
+<p>The hunter decided to try to get to closer quarters where he could use
+his spear on the body of the beast. He stooped down and wiggled along on
+the bottom of the cave. But the creature saw him, and darted an arm out
+to pull the old man in. Andy squirmed to one side, and then, being as
+close as he desired, he rose to his feet and, drawing back the pole
+thrust it with all his force straight at the centre of the
+whitish-yellow body that was like a horrible lump of soft fat directly
+in front of him.</p>
+
+<p>At the first touch of the knife the creature squirted out an inky
+substance that made the water about it as black as night. Andy could not
+see, but he could feel that the lance was still in the body. He pulled
+it back a little and thrust again and again, turning it around to
+enlarge the wound he had made.<span class='pagenum'><a name="Page_225" id="Page_225">[225]</a></span></p>
+
+<p>Then, what he had feared all along happened. Two of the creatures arms
+found him, and he felt the terrible pressure as they wound themselves
+about him, the sucker-plates clinging fast. Yet in it all he did not
+lose his presence of mind, nor did he let go of the pole.</p>
+
+<p>Tighter and tighter the arms clasped him. He struggled with all his
+strength but he was in a grip more powerful than that of a boa
+constrictor. Suddenly the pole he was holding snapped off. He let go the
+useless end and pulled the shorter part, to which the knife was bound,
+toward him. Andy felt his senses beginning to leave him, but he
+determined to make one more effort.</p>
+
+<p>One hand was free, that holding the knife. With his last remaining
+strength he cut and slashed at the arms of the creature that were
+clasped about him.</p>
+
+<p>Again and again he stuck the blade into the gristle like substance.
+Could he win? Could he save his own life, to say nothing of that of the
+two boys?</p>
+
+<p>The creature was lashing about now so that the water was a mass of black
+foam. The ink-color was beginning to fade away. Andy could dimly observe
+the horrible front of the octupus, and see the wound his lance had made.
+Then all seemed to grow dark again. He dimly remembered try<span class='pagenum'><a name="Page_226" id="Page_226">[226]</a></span>ing to
+thrust the knife into one of the saucer-shaped eyes, and then of a
+sudden his senses left him.</p>
+
+<p>When Andy came to his senses he found himself lying on the ocean bed
+just outside the cave. About him stood the professor, Washington, Tom
+and Bill. His head buzzed and he felt weak, but he knew he was
+uninjured, and that his diving suit had not been punctured in the fight
+with the octupus, for he could feel the fresh air entering from the tank
+at the back of his helmet.</p>
+
+<p>Were the boys killed, Andy wondered. Had his fight to save them been in
+vain? He managed to stand up, and then, to his relief he saw Mark and
+Jack standing behind Tom and Bill. The boys seemed weak but otherwise
+uninjured.</p>
+
+<p>The professor motioned to know if Andy could walk and the old hunter
+soon demonstrated that he could by stepping forward. Then the party
+proceeded slowly to the ship.</p>
+
+<p>Little time was lost by each one in divesting himself of his diving suit
+as soon as they had left the water chamber. The first thing Andy asked
+when his <ins title="Transcriber's Note: original reads 'hemlet'">helmet</ins> was off, was:</p>
+
+<p>"Did I kill the beast?"</p>
+
+<p>"Indeed you did," replied the professor. "And just in time, too. You
+were about done for when we came back with the guns, but they were<span class='pagenum'><a name="Page_227" id="Page_227">[227]</a></span> not
+needed. My! But you must have had a terrible fight!"</p>
+
+<p>"I did, while it lasted," said the hunter. "But were the boys hurt?"</p>
+
+<p>"They can speak for themselves," replied Mr. Henderson. "I guess not,
+though."</p>
+
+<p>"Having the wind almost squeezed out of us was the worst that happened,"
+said Mark. "The octupus must have recently dined when it grabbed us, for
+it didn't offer to eat us. And it didn't grip us as tightly as it might
+have or I reckon we wouldn't have come out alive. I thought sure we were
+going to be killed, however."</p>
+
+<p>"So did I," put in Jack.</p>
+
+<p>"I don't want any more such fights this trip," said Andy with a weak
+smile.<span class='pagenum'><a name="Page_228" id="Page_228">[228]</a></span></p>

+<h2>CHAPTER XXVIII</h2>
+
+<h3>OUT OF THE ICE</h3>
+
+
+<p>Worn out with their encounter with the octupus, Andy and the boys were
+glad to take to their bunks. The others, too, who were weary from
+traveling under water, felt the need of rest, and so it was decided to
+let the ship remain stationary down on the bottom of the ocean for
+several hours before going on further.</p>
+
+<p>"When we get rested up we'll have a good meal, and then try to gain the
+surface of the ocean," said the professor.</p>
+
+<p>There was quiet on board the <i>Porpoise</i> for a long time. Washington was
+the first to awake and he at once set about getting a meal. When it was
+ready he called the professor, and, one after another all the
+adventurers rose from their bunks and refreshed themselves with hot
+coffee, bacon, eggs and preserves, all prepared from condensed foods, of
+which a large supply had been brought.</p>
+
+<p>"Now to see if we can make our way upward through the ice," announced
+Mr. Henderson.<span class='pagenum'><a name="Page_229" id="Page_229">[229]</a></span></p>
+
+<p>"We ought to be far enough south to strike the open polar <ins title="Transcriber's Note: original reads 'see'">sea</ins> which I
+believe exists."</p>
+
+<p>The engine was started after the small leaks in the bow, caused by the
+ramming of the boat on the rocks, had been stopped up, and the
+professor, entering the conning tower, turned her due south.</p>
+
+<p>The screw vibrated in the tunnel, the water rushed out in a big stream,
+the engines and dynamos hummed, and the hearts of all were lightened as
+they knew they were nearing the goal of their journey.</p>
+
+<p>Several hours passed and the professor, who was keeping watch of the
+gages noted they had covered more than one hundred miles. As the supply
+of compressed air was getting low Mr. Henderson, not wanting to run any
+chances, decided to make an attempt to reach the surface and refill the
+tanks.</p>
+
+<p>Accordingly the water tanks were emptied of their ballast, the rudder
+was set to force the ship to the surface, and soon the depth gage showed
+a constantly decreasing amount of water over the heads of the
+adventurers.</p>
+
+<p>"Now, if we don't hit the ice above us we'll be all right," spoke Mr.
+Henderson. "We are within fifteen feet of the surface."</p>
+
+<p>Hardly had he ceased speaking when the <i>Porpoise</i> brought up against
+something with a bump<span class='pagenum'><a name="Page_230" id="Page_230">[230]</a></span> that jarred everyone. Then the submarine went
+scraping along, hitting the conning tower every now and then.</p>
+
+<p>"Not clear of the ice yet," said Mr. Henderson. "We must go down a
+little and try again."</p>
+
+<p>The tanks were filled with enough water to keep the boat about fifty
+feet under the surface, and at that depth she was sent ahead at full
+speed. The professor's face wore an anxious look, and when Washington
+asked him if it was not time to replenish the air supply of the boat the
+inventor told the colored man to be very sparing of the contents of the
+compressing tanks.</p>
+
+<p>"I'm afraid we are not as near the open sea as I at first thought," Mr.
+Henderson finished.</p>
+
+<p>On and on rushed the <i>Porpoise</i>. The engines were kept at full speed,
+and after two hours of this fast run another attempt was made to reach
+the surface. Once more the thick ice intervened.</p>
+
+<p>"Guess we'll have to blast our way out," observed Andy. "We seem to have
+lots of trouble on this trip."</p>
+
+<p>"Why not try to ram your way through," suggested Jack.</p>
+
+<p>"How do you mean?" asked Mr. Henderson.</p>
+
+<p>"I mean to sink the boat say two hundred feet. Then start her up
+obliquely and perhaps the sharp prow will cut a hole through the ice."<span class='pagenum'><a name="Page_231" id="Page_231">[231]</a></span></p>
+
+<p>"Hardly through ice fifteen feet or more thick," said the captain
+despondently.</p>
+
+<p>"But it may be thinner now," persisted Jack.</p>
+
+<p>"At any rate it will do no harm to try," the inventor admitted. "We can
+not last much longer down here."</p>
+
+<p>Again the tanks were filled, and by the aid of the deflecting rudder the
+<i>Porpoise</i> went down into the depths. Then the ballast tanks were
+quickly emptied, and the rudder turned so as to force the craft upward
+on a slant. The engine was set going at top speed.</p>
+
+<p>"Hold fast everybody!" called the professor. "It is kill or cure this
+trip!"</p>
+
+<p>Like an arrow from a bow the <i>Porpoise</i> shot upward. On and on it <ins title="Transcriber's Note: original reads 'speed'">sped</ins>,
+gathering momentum with every foot she traveled.</p>
+
+<p>Suddenly there came a terrible crash, a grinding sound and a rending and
+tearing. The ship trembled from end to end. Every one was knocked from
+his feet. There were bumpings and scrapings all along the sides of the
+submarine. Then, with one final spurt of speed, the little ship tore her
+way through the ice and emerged, with a splash and shower of foam into
+the open sea!</p>
+
+<p>Quickly the man hole was opened and, half dead from lack of fresh air,
+the adventurers crawled out on deck. It was night and the stars
+glittered in<span class='pagenum'><a name="Page_232" id="Page_232">[232]</a></span> the sky above. They were just beyond the edge of the ice
+field, and all about them was a wide open sea.</p>
+
+<p>"I was right after all," said the professor, "but I miscalculated the
+distance. Had we gone on a few feet farther it would not have been
+necessary to break through the ice."</p>
+
+<p>"I guess it's a lucky thing we didn't try it before either," remarked
+Andy. "We never could have bored through fifteen feet of the frozen
+stuff. Where we plowed up it is less than two feet," and he pointed to
+where the immense floe came to an end.</p>
+
+<p>It was decided to go no farther that night, however, as the professor
+wanted to take some observations by daylight and ascertain his position.
+So filling their lungs with the air, cold and piercing though it was,
+the adventurers descended to their cabin, and lots were drawn to see who
+would stand the two night watches. It fell to Mr. Henderson to take the
+first, and Washington the second. The captain accordingly took up his
+position in the conning tower and prepared to pass several hours.</p>
+
+<p>He was busy thinking over the exciting times he and his companions had
+passed through, and planning new trips to see more wonders of the world,
+when his attention was attracted by slight noise<span class='pagenum'><a name="Page_233" id="Page_233">[233]</a></span> near the man hole
+leading to the amidship companionway.</p>
+
+<p>The professor looked up, and was startled to see a tall white object,
+with outstretched arms advancing toward him with slow and stealthy
+tread.</p>
+
+<p>"The ghost again!" exclaimed the inventor softly. "I must catch it now,
+and see what foolishness it is," for the professor did not believe in
+spirits.</p>
+
+<p>He got down on his hands and knees the better to escape observation,
+should the white thing prove to be a bodily substance, and started to
+crawl toward it. He came within ten feet of the thing, and could make
+out that it was a man, or at least the semblance of one, all clothed in
+white.</p>
+
+<p>Nearer and nearer the inventor crawled to the thing. It turned to face
+him now and Mr. Henderson could not help feeling startled as he saw the
+object had no head. The neck ended in a white stump.</p>
+
+<p>In spite of a little feeling of qualmishness, which even his boasted
+disbelief in ghosts did not save him from, Mr. Henderson was about to
+spring upon the thing and solve the mystery.</p>
+
+<p>At that instant, however, Washington, who was coming on deck to take up
+his watch, appeared at the head of the companionway, and caught sight of
+the terrible object.<span class='pagenum'><a name="Page_234" id="Page_234">[234]</a></span></p>
+
+<p>The yells of the colored man as he dove downward and back into the
+cabin, aroused the ship. Determined to solve the mystery, in spite of
+everything, the professor made a leap forward. He slipped, and tumbled
+down the iron stairway. At the same time, the ghost, with a blood
+curdling yell, leaped over the professor's back, and disappeared down
+the stairs of the conning tower.</p>
+
+<p>In an instant the crew were rushing from their bunk rooms, seeking a
+meaning for the disturbance.</p>
+
+<p>"It was the ghost again," explained the professor as he picked himself
+up, not much the worse for his tumble. "I tried to catch it, but I
+didn't. Come, Washington, it is your turn to stand watch."</p>
+
+<p>"Not to-night," said Washington firmly.</p>
+
+<p>It was no use to urge him, so Jack good-naturedly stood Washington's
+trick. Nothing further however occurred that night.</p>
+
+<p>In the morning the professor made several observations and found that he
+was within one hundred and fifty miles of the south pole.</p>
+
+<p>"We'll make it to-morrow, if we have luck," he said.<span class='pagenum'><a name="Page_235" id="Page_235">[235]</a></span></p>
+
+
+
+<hr style="width: 65%;" />
+<h2>CHAPTER XXIX</h2>
+
+<h3>THE BOILING WATER</h3>
+
+
+<p>The hours passed and the strange voyage continued.</p>
+
+<p>The <i>Porpoise</i> traveled along at good speed, and the professor devoted
+most of his time to looking after the different scientific instruments
+and gages, for they were nearing the south pole. The deflecting compass,
+which when it came directly over the place corresponding to the pole,
+would point straight up and down, was assuming more and more of a
+perpendicular position.</p>
+
+<p>"We are getting there!" exclaimed the professor with delight. "A few
+hours more and we will have won the goal!"</p>
+
+<p>There was considerable excitement on board when the professor's
+announcement was made. Though few of the adventurers cared as much for
+the scientific achievement as did Mr. Henderson, they were all glad he
+was about to succeed. To most of them the locating of the south pole was
+no different from visiting some new country, except<span class='pagenum'><a name="Page_236" id="Page_236">[236]</a></span>ing that there were
+more adventures than on most voyages.</p>
+
+<p>At dusk the <i>Porpoise</i> went to the surface and during the night traveled
+along atop of the billows. In the morning she dived below again. The
+engine was started at high speed and the deflecting needle dipped still
+more.</p>
+
+<p>"We's gittin' dar!" exclaimed Washington as he oiled the various
+bearings of the machinery.</p>
+
+<p>Breakfast was served and <ins title="Transcriber's Note: original reads 'hurridly'">hurriedly</ins> eaten, for the excitement was telling
+on every one. After the meal had been cleared away they all sat in the
+darkened cabin looking out at the water as it slipped past the glass
+windows. Big and little fish swam up and peered into the bull's-eyes and
+then darted away.</p>
+
+<p>"That's sort of queer," remarked Jack a little later.</p>
+
+<p>"What is?" asked Mark, who was sitting near his chum.</p>
+
+<p>"All the fish seem to have suddenly disappeared," replied Jack. "There
+were hundreds a little while ago, and now I haven't seen one looking in
+the windows for some time."</p>
+
+<p>"Perhaps there's a big fish on their trail," observed Mark. "That's what
+makes 'em take to the deep sea weed."</p>
+
+<p>"Maybe so," replied Jack.<span class='pagenum'><a name="Page_237" id="Page_237">[237]</a></span></p>
+
+<p>A little later Professor Henderson entered the room. He went over,
+looked at the thermometer, and then called to Washington:</p>
+
+<p>"Have you got the heat turned on?"</p>
+
+<p>"No, sah! I ain't done truned on no superheated vapor into de
+radiators," replied the colored man. "I were jest thinkin' dat we'd hit
+de south pole by de feel of it."</p>
+
+<p>"It is getting strangely warm," admitted Mr. Henderson.</p>
+
+<p>"Ain't that what you expected at the south pole?" asked Andy. "I thought
+it was hot at the south pole and cold at the north."</p>
+
+<p>"That's what lots of people imagine," said the professor, "but except
+for the open sea, which I have proved does exist, I guess it's just as
+cold at the south as at the north, especially in the winter. We have
+struck the summer season."</p>
+
+<p>"And a mighty warm one at that," observed Jack. "Whew! I've got to take
+off my coat."</p>
+
+<p>Indeed it was getting uncomfortably warm in the ship, and the
+adventurers who had dressed in thick clothing to guard against the
+rigors of the icy climate, soon had to lay aside many of their garments.</p>
+
+<p>"No wonder!" exclaimed Mr. Henderson, as he looked at a thermometer. "It
+is eighty degrees in here!"<span class='pagenum'><a name="Page_238" id="Page_238">[238]</a></span></p>
+
+<p>"Worse than workin' in a hay field," observed Bill, as he wiped the
+beads of perspiration from his forehead.</p>
+
+<p>"Let us see what sort of water we are traveling through," suggested the
+professor, as he again turned off the lights in the cabin so that a view
+could be had from the bull's-eyes.</p>
+
+<p>Wondering what would meet their gaze the adventurers peered out of the
+small circular windows. At first they could hardly believe their eyes.</p>
+
+<p>There, right before them, the sea was bubbling as if it was an immense
+tea kettle. Steam formed on the glass, and big clouds of vapor could be
+seen. The atmosphere of the cabin became almost unbearable.</p>
+
+<p>"We are in the midst of a boiling hot ocean!" cried the professor.</p>
+
+<p>"Are we sailing through hot water?" asked Andy.</p>
+
+<p>"I should say so, from the feel of it," answered Mr. Henderson. "Put
+your hand on the side of the cabin."</p>
+
+<p>Andy laid his fingers against the steel plates. He drew back.</p>
+
+<p>"I burned myself!" he exclaimed.</p>
+
+<p>"What are we to do?" cried Jack.</p>
+
+<p>"Get out of this by all means!" exclaimed the inventor. "If we stay in
+this hot ocean we will<span class='pagenum'><a name="Page_239" id="Page_239">[239]</a></span> be boiled alive like fishes in a pot. Send the
+ship up, Washington!"</p>
+
+<p>Indeed it was high time. The thermometer marked one hundred and ten
+<ins title="Transcriber's Note: original reads 'degress'">degrees</ins>, and was rising. The interior of the <i>Porpoise</i> was like that of
+a steam laundry three times heated. Stripped to their undergarments the
+adventurers were obliged to lie down on the floor of the cabin where it
+was a little cooler.</p>
+
+<p>It was all Washington could do, used as colored people are to the heat,
+to go into the engine room, and start the machinery that emptied the
+tanks, so as to allow the ship to mount to the surface.</p>
+
+<p>The <i>Porpoise</i> began to rise slowly, and to the suffering men and boys
+it seemed that she never went up so reluctantly. The heat was becoming
+unbearable. They could hear the water bubbling even through the steel
+sides of the submarine.<span class='pagenum'><a name="Page_240" id="Page_240">[240]</a></span></p>

+<h2>CHAPTER XXX</h2>
+
+<h3>CONCLUSION</h3>
+
+
+<p>Could they live to reach the surface? was the thought in the mind of
+every one. The heat was terrific. They were breathing in gasps.
+Professor Henderson went to the water tank, thinking to throw some of
+the fluid over himself and his companions, but he found it so warm that
+it almost burned his hand.</p>
+
+<p>"Keep up your courage!" exclaimed the inventor. "We will soon be at the
+top!"</p>
+
+<p>Almost as he spoke the <i>Porpoise</i> bounded from the waves, and fell back
+in a splash of foam on the surface of the billows. They were at the
+surface.</p>
+
+<p>The professor rushed for the manhole and soon opened it. He crawled out
+on the deck, followed by the others. They breathed in deep breaths of
+the fresh air.</p>
+
+<p>The submarine continued to sail on. Every minute the sea seemed to boil
+more violently, until at last the waves were covered with a cloud of
+steam, through which it was difficult to observe where they were going.<span class='pagenum'><a name="Page_241" id="Page_241">[241]</a></span></p>
+
+<p>"Hadn't we better turn back," suggested Mark.</p>
+
+<p>"Our only hope is to press on," replied Mr. Henderson. "We may cross
+this zone of boiling water soon."</p>
+
+<p>He went into the conning tower to make an observation. He came on the
+deck the next minute, very much excited.</p>
+
+<p>"What's the matter? Are we sinking?" asked Andy.</p>
+
+<p>"We are directly over the south pole!" exclaimed the professor. "We have
+reached the goal! We have come to the spot hundreds of men have tried to
+reach! It has been left for us to succeed. Look at the deflecting
+needle!"</p>
+
+<p>They crowded into the conning tower to note it. The slender hand of
+steel stood straight up and down, indicating that the ship was over the
+south pole, one of the two chief centres of magnetism of the earth.</p>
+
+<p>"If we only dared stop to make some scientific notes and observations,"
+said the professor, "we could render much valuable aid to the seekers
+after truth. But it would be sure death to stay in the boiling water!"</p>
+
+<p>"I guess we'd better be getting out of this if we want to reach home
+alive," spoke Andy.</p>
+
+<p>Indeed they were all suffering very much, for the heat from the water
+was awful.<span class='pagenum'><a name="Page_242" id="Page_242">[242]</a></span></p>
+
+<p>"Speed her up, Washington!" called the professor. "We must get out of
+here!"</p>
+
+<p>"Which way shall I steer?" asked the colored man.</p>
+
+<p>"Straight ahead. We are now bound north!"</p>
+
+<p>"Bound north!" cried Jack.</p>
+
+<p>"Certainly," answered the professor. "We have passed over the exact spot
+where the south pole is. The deflecting needle is beginning to tilt
+again. The compass is indicating a northerly direction. You know that
+after you go as far south as you can, you have to begin to go back
+north. Well, we have gone as far south as we can. Now we are going
+north. We have turned the southern end of the globe, and are on our way
+back."</p>
+
+<p>For several hours the <i>Porpoise</i> continued along on top of the water. By
+degrees, as they left the vicinity of the boiling ocean, it became
+cooler. The water ceased to <ins title="Transcriber's Note: original reads 'seeth'">seethe</ins> and bubble, and Jack found, on
+experiment, that he could bear his hand in it.</p>
+
+<p>"Hurrah!" he cried, "we are safe now."</p>
+
+<p>"Next we'll have to prepare to freeze to death," spoke Mark. "It's
+either one extreme or the other this trip. But we've had lots of fun and
+excitement."</p>
+
+<p>"Plenty of the last," agreed Jack.</p>
+
+<p>On and on went the submarine. Once it was<span class='pagenum'><a name="Page_243" id="Page_243">[243]</a></span> out of the range of the
+terrible heated zone, the atmosphere rapidly cooled, until the
+adventurers were glad to don their heavy garments again.</p>
+
+<p>"This marks the ending of the first half of the voyage," announced the
+professor. "Now we are going back. We have accomplished something no
+other living man has done and I am proud of it. Proud of all of you, and
+proud of the ship!"</p>
+
+<p>Several hours later, when it was deemed safe, the <i>Porpoise</i> was sunk
+beneath the waves, and once <ins title="Transcriber's Note: original reads 'more more'">more</ins> she speeded along through the water at
+a fast speed. The ship seemed to know she was going home, for never had
+she made better time.</p>
+
+<p>"We have solved every problem that we met," said the professor while he,
+with Jack and Mark, were in the conning tower, as Washington was
+preparing a meal.</p>
+
+<p>"Except two," said Jack.</p>
+
+<p>"What are they?"</p>
+
+<p>"The ghost of the submarine, and the identity of the anarchists who blew
+up the Easton hotel."</p>
+
+<p>"Perhaps both riddles may be solved before we get back to Maine,"
+answered Mr. Henderson.</p>
+
+<p>They both were, sooner, and in stranger ways than either of the boys
+expected. That night it was Jack's first watch on deck. The ship was<span class='pagenum'><a name="Page_244" id="Page_244">[244]</a></span>
+speeding on, and by the air the boy knew they were approaching icebergs.
+At midnight a strange and sudden chill in the air made him look up.</p>
+
+<p>Almost dead ahead was a big berg. He quickly shut off the engine, and
+narrowly avoided a collision. Then happening to glance back he saw,
+standing near the companionway leading down into the man-hole a ghostly
+white shape.</p>
+
+<p>"I'll find out what you are this time, or go overboard with you," said
+Jack to himself, clenching his teeth. He crawled along the deck until he
+thought he was within leaping distance of the weird white thing. Then he
+made a leap.</p>
+
+<p>He landed on something soft, which, the moment he struck it, let out a
+yell that sounded loud on the quiet night. Then the thing began to
+fight. But Jack fought back and held on bravely.</p>
+
+<p>"Here! What are you tryin' to do?" exclaimed a voice in his ear.</p>
+
+<p>"What are you trying to do?" asked Jack indignantly, finding that the
+words came from the "ghost."</p>
+
+<p>"Nice way to treat a man! Half kill him!" the white thing went on. "Just
+when I'm trying to get a little sleep you come along and pull me out of
+bed!"</p>
+
+<p>"Why, it's Bill Jones," exclaimed Jack, as the<span class='pagenum'><a name="Page_245" id="Page_245">[245]</a></span> light from the conning
+tower lamp fell on the face of the "ghost."</p>
+
+<p>"Of course it is; who did you think it was?" asked Bill.</p>
+
+<p>"What are you doing on deck in your night shirt?" asked the boy, letting
+the helper rise.</p>
+
+<p>"Me? On deck? Ain't I in my bunk?"</p>
+
+<p>"I should say not," replied Jack. "What are you doing on deck?"</p>
+
+<p>"Well! well!" remarked Bill, rubbing his eyes. "I've gone and done it
+again."</p>
+
+<p>"Done what?"</p>
+
+<p>"Walked in my sleep. I'm a great sleep walker. Greatest you ever knew.
+Once I climbed to the top of our barn when I was asleep."</p>
+
+<p>"So you're the ghost of the submarine," exclaimed Jack. "That explains
+it."</p>
+
+<p>"I guess you're right," admitted Bill, as the others came on deck to see
+what all the row was about. "I never thought of it when I heard about
+the ghost, but I can account for it now. I'd get out of my bunk, wander
+out on deck, and then crawl back again. Of course, being barefoot, or in
+fur slippers, I made no sounds. I don't wonder you thought I was a
+spirit. Queer I didn't wake up after some of the things I went through."</p>
+
+<p>"And you always managed to get back to your<span class='pagenum'><a name="Page_246" id="Page_246">[246]</a></span> bunk in time so that we
+never caught you at it," said Jack. "However, it's all over now."</p>
+
+<p>And so it was, for after that Bill tied a chair in front of his bunk,
+and if he did get out in his sleep he stumbled against it and awoke
+before he had gone far.</p>
+
+<p>Northward the <i>Porpoise</i> continued on her journey. She entered a vast
+field of ice, and only her ability to sink below the surface enabled her
+to get through it unharmed. There were few adventures going home. Once a
+big whale rammed the ship, as had happened on the going voyage, and
+several times they were surrounded by hordes of wild polar fish and
+walrusses, but there were no accidents, and in a couple of weeks the
+ship entered the temperate zone.</p>
+
+<p>Then came lazy happy days of sailing through the tropical region. They
+landed at several islands and renewed their supply of food.</p>
+
+<p>"I'm coming back this way some day," observed Mr. Henderson one
+afternoon as the ship was sailing along on top of the waves.</p>
+
+<p>"What for?" asked Jack.</p>
+
+<p>"To investigate that strange island with a big hole in the middle that
+seems to lead to the centre of the earth," was the answer. "I have a
+fancy we can explore that by means of a balloon. I'm going to try."<span class='pagenum'><a name="Page_247" id="Page_247">[247]</a></span></p>
+
+<p>"Will you take us along?" asked the two boys.</p>
+
+<p>"I'll see," replied the professor.</p>
+
+<p>And later on he did take them on a trip, a thousand miles
+underground,&mdash;but that is another story to tell.</p>
+
+<p>It was about a week later that the voyagers came within sight of Key
+West.</p>
+
+<p>"Off there lies the United States," said Mr. Henderson.</p>
+
+<p>"Hurrah for home!" cried Mark.</p>
+
+<p>Three days later they landed at a small Florida town. The sight of the
+<i>Porpoise</i> attracted throngs of people to the dock where she tied up.
+Among them was a newsboy.</p>
+
+<p>"Get me all the papers for the past month," said Jack. "I want to see
+what the news is."</p>
+
+<p>"Same here," put in Mark, and the papers were soon brought.</p>
+
+<p>"Hurrah!" exclaimed Jack, as soon as he had looked at several of the
+sheets.</p>
+
+<p>"What is it?" asked Mark, who was unfolding a paper.</p>
+
+<p>"Anarchists Confess," read Jack. "Two Englishmen Admit They Blew Up
+Hotel Where Lord Peckham Was Stopping. No Suspicion Attaches to Two
+Youths Who So Mysteriously Disappeared!"</p>
+
+<p>"Hurrah!" joined in Mark.<span class='pagenum'><a name="Page_248" id="Page_248">[248]</a></span></p>
+
+<p>"Those are only the head lines," went on Jack. "There's a long story,
+and I guess it lets us out."</p>
+
+<p>The two boys were completely cleared of the slightest shade of suspicion
+of the outrage, and there was even an interview with the English
+detective in which he admitted that he was wrong.</p>
+
+<p>A week later the <i>Porpoise</i> tied up at her own dock, whence she was
+launched.</p>
+
+<p>"Back again," remarked the professor as he stepped ashore. "I've been to
+the south pole, and to the north pole. I wonder where I shall go next?"</p>
+
+<p>"To the big hole and underground," suggested Jack.</p>
+
+<p>"We shall see," said Mr. Henderson with a twinkle in his eyes.</p>

+ must be paid within 60 days following each date on which you
+ prepare (or are legally required to prepare) your periodic tax

+ destroy all copies of the works possessed in a physical medium
+ and discontinue all use of and all access to other copies of
+ Project Gutenberg-tm works.

+
+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH F3. YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can
+receive a refund of the money (if any) you paid for it by sending a

+received the work on a physical medium, you must return the medium with
+your written explanation. The person or entity that provided you with
+the defective work may elect to provide a replacement copy in lieu of a
+refund. If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund. If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+
+1.F.4. Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER

+warranties or the exclusion or limitation of certain types of damages.
+If any disclaimer or limitation set forth in this agreement violates the
+law of the state applicable to this agreement, the agreement shall be
+interpreted to make the maximum disclaimer or limitation permitted by
+the applicable state law. The invalidity or unenforceability of any
+provision of this agreement shall not void the remaining provisions.
+
+1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the
+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,

+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, is critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at
+http://pglaf.org/fundraising. Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.
+
+The Foundation's principal office is located at 4557 Melan Dr. S.
+Fairbanks, AK, 99712., but its volunteers and employees are scattered
+throughout numerous locations. Its business office is located at
+809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email
+business@pglaf.org. Email contact links and up to date contact
+information can be found at the Foundation's web site and official
+page at http://pglaf.org
+
+For additional contact information:
+ Dr. Gregory B. Newby
+ Chief Executive and Director
+ gbnewby@pglaf.org
+
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.

+CHAPTER I
+
+WILL THE SHIP WORK?
+
+
+"Hand me that wrench, Mark," called Professor Amos Henderson to a boy
+who stood near some complicated machinery over which the old man was
+working. The lad passed the tool over.
+
+"Do you think the ship will work, Professor?" he asked.
+
+"I hope so, Mark, I hope so," muttered the scientist as he tightened
+some bolts on what was perhaps the strangest combination of apparatus
+that had ever been put together. "There is no reason why she should not,
+and yet--"
+
+The old man paused. Perhaps he feared that, after all, the submarine
+boat on which he had labored continuously for more than a year would be
+a failure.
+
+"Is there anything more I can do now?" asked Mark.
+
+"Not right away," replied the professor, without looking up from the
+work he was doing. "But I wish you and Jack would be around in about an
+hour. I am going to start the engine then, and I'll need you. If you see
+Washington outside send him to me."
+
+Mark left the big room where the submarine boat had been in process of
+construction so long. Outside he met a boy about his own age, who was
+cleaning a rifle.
+
+"How's it going, Mark?" asked this second youth, who was rather fat,
+and, if one could judge by his face, of a jolly disposition.
+
+"The professor is going to try the engine in about an hour," replied
+Mark. "We must be on hand."
+
+"I'll be there all right. But if there isn't anything else to do, let's
+shoot at a target. I'll bet I can beat you."
+
+"Bet you can't. Wait 'till I get my gun."
+
+"Now don't yo' boys go to disportin' yo'seves in any disproportionable
+anticipation ob transposin' dem molecules of lead in a contigious
+direction to yo' humble servant!" exclaimed a colored man, coming from
+behind the big shed at that moment, and seeing Mark and Jack with their
+rifles.
+
+"I s'pose you mean to say, Washington," remarked Jack, "that you don't
+care to be shot at. Is that it?"
+
+"Neber said nuffin truer in all yo' born days!" exclaimed Washington
+earnestly. "De infliction ob distress to de exterior portion ob--"
+
+"The professor wants you," interrupted Mark, cutting off the colored
+man's flow of language.
+
+"Yo' mind what I tole yo'," Washington muttered as he hurried into the
+work room.
+
+Soon the reports of rifles indicated that the boys were trying to
+discover who was the best shot, a contest that waged with friendly
+interest for some time.
+
+The big shed, where the submarine ship was being built, was located at a
+lonely spot on the coast of Maine. The nearest town was Easton, about
+ten miles away, and Professor Henderson had fixed on this location as
+one best suited to give him a chance to work secretly and unobserved on
+his wonderful invention.
+
+The professor was a man about sixty-five years old, and, while of simple
+and kindly nature in many ways, yet, on the subjects of airships and
+submarines, he possessed a fund of knowledge. He was somewhat queer, as
+many persons may be who devote all their thoughts to one object, yet he
+was a man of fine character.
+
+Some time before this story opens he had invented an electric airship in
+which he, with Mark Sampson, Jack Darrow and the colored man,
+Washington White, had made a trip to the frozen north.
+
+Their adventures on that journey are told of in the first volume of this
+series, entitled, "Through the Air to the North Pole, or, The Wonderful
+Cruise of the _Electric Monarch_."
+
+The two boys, Mark then being fifteen and Jack a year older, had met the
+professor under peculiar circumstances. They were orphans, and, after
+knocking about the world a bit, had chanced to meet each other. They
+agreed to seek together such fortune as might chance to come to them.
+
+While in the town of Freeport, N. Y., they were driven away by a
+constable, who said tramps were not allowed in the village. The boys
+jumped on a freight train, which broke in two and ran away down the
+mountain, and the lads were knocked senseless in the wreck that
+followed.
+
+As it chanced Professor Henderson had erected nearby a big shop, where
+he was building his airship. He and Washington were on hand when the
+wreck occurred and they took the senseless boys to the airship shed.
+
+The boys, after their recovery, accepted the invitation of the professor
+to go on a search for the north pole. As the airship was about to start
+Andy Sudds, an old hunter, and two men, Tom Smith and Bill Jones, who
+had been called in to assist at the flight, held on too long and were
+carried aloft.
+
+Somewhat against their will the three latter made the trip, for the
+professor did not want to return to earth with them.
+
+The party had many adventures on the voyage, having to fight savage
+animals and more savage Esquimaux. They reached the north pole, but in
+the midst of such a violent storm that the ship was overturned, and the
+discovery of the long-sought goal availed little. After many hardships,
+and a fierce fight to recover the possession of the ship, which had been
+seized by natives, the adventurers reached home.
+
+Since then a little over a year had passed. The professor, having found
+he could successfully navigate the air, turned his attention to the
+water, and began to plan a craft that would sail beneath the ocean.
+
+To this end he had moved his machine shop to this lonely spot on the
+Maine coast. The two boys, who had grown no less fond of the old man
+than he of them, went with him, as did Washington White, the negro, who
+was a genius in his way, though somewhat inclined to use big words, of
+the meaning of which he knew little and cared less.
+
+Andy Sudds, the old hunter, had also been induced to accompany the
+professor.
+
+"I hunted game up north and in the air," said Andy, "and if there's a
+chance to shoot something under the water I'm the one to do it."
+
+Needing more assistance than either the boys, Andy or Washington could
+give, the professor had engaged two young machinists, who, under a
+strict promise never to divulge any of the secrets of the submarine, had
+labored in its building.
+
+Now the queer craft was almost finished. As it rested on the ways in the
+shed, it looked exactly like a big cigar, excepting that the top part
+was level, forming a platform.
+
+The ship, which had been named the _Porpoise_, was eighty feet long, and
+twenty feet in diameter at the largest part. From that it tapered
+gradually, until the ends were reached. These consisted of flattened
+plates about three feet in diameter, with a hole in the center one foot
+in size.
+
+Weary months of labor had been spent on the _Porpoise_, until now it was
+almost ready for a trial. The professor had discovered a new method of
+propulsion. Instead of propellers or paddle-wheels, he intended to send
+his craft ahead or to the rear, by means of a water cable.
+
+Through the entire length of the ship ran a round hole or shaft, one
+foot in diameter. Within this was an endless screw worked by powerful
+engines. With a working model the professor had demonstrated that when
+the endless screw was revolved it acted on the water just as another
+sort of screw does in wood. The water coming in through the shaft served
+as a rope, so to speak, and the screw, acting on it, pulled the craft
+ahead or to the rear, according to the direction in which the screw was
+revolved.
+
+The submarine was a wonderful craft. It contained a powerful engine,
+electric motors and dynamos, and machinery of all kinds. The engine was
+a turbine, and steam was generated from heat furnished by the burning of
+a powerful gas, manufactured from sea water and chemicals. So there was
+no need to carry a supply of coal on the ship.
+
+The interior of the vessel was divided into an engine-room, a kitchen,
+combination dining-room and parlor, bunk rooms, and a conning tower, or
+place for the steersman.
+
+While the boys had been shooting at the target the professor and
+Washington had been putting the finishing touches to the engine,
+tightening nuts here and screwed up bolts there.
+
+"I guess that will do," remarked the old inventor. "Call the boys,
+Washington."
+
+The colored man went to the door and gave three blasts on a battered
+horn that hung from a string.
+
+"Coming!" called Mark, as he and Jack ceased their marksmanship contest
+and approached the shed.
+
+"Now boys, we'll see if she works so far," said the professor. "If she
+does, we'll give her a trial under water."
+
+At the inventor's directions the boys started the gas to generating from
+the chemicals. Soon the hissing of steam told them that there was power
+in the boiler.
+
+The professor entered the engine-room of the submarine. He looked over
+the various wheels, levers, handles, gages and attachments, satisfying
+himself that all were in proper shape and position.
+
+"Three hundred pounds pressure," he muttered, glancing at the steam
+indicator. "That ought to be enough. Are you all ready, boys?"
+
+"All ready!" cried Jack.
+
+Of course the test was only one to see if the engine worked, for the
+boat could not move until in the water.
+
+The professor opened a valve. The steam filled the turbine with a hiss
+and throb. The _Porpoise_ trembled. Then, with a cough and splutter of
+the exhaust pipes, the engine started. Slowly it went at first, but, as
+the professor admitted more steam, it revolved the long screw until it
+fairly hummed in the shaft.
+
+"Hurrah! It works!" cried Mark.
+
+"It does!" chimed in Jack.
+
+"Gollyation! She suttinly am goin'!" yelled Washington.
+
+"I think we may say it is a success," said the professor calmly, yet
+there was a note of exultation in his voice.
+
+"Now that you've got her started, when are you goin' to put her in the
+water an' scoot along under the waves?" asked Andy Sudds.
+
+"In about a week," replied the professor.
+
+"And where are you goin' to head for?" went on the hunter.
+
+"We're going under the ocean to the south pole!" exclaimed the inventor,
+as he shut off the engine.
+
+
+
+
+CHAPTER II
+
+A LAND OF ICE
+
+
+"The south pole?" exclaimed Mark.
+
+"Way down dat way!" cried Washington.
+
+"Can you do it?" asked Jack.
+
+"That remains to be seen," replied the professor, answering them all at
+once. "I'm going to try, at any rate."
+
+"Hurrah!" yelled Mark. "It will be better than going to the north pole,
+for we will be in no danger of freezing to death."
+
+"Don't be so sure of that," interrupted the professor. "There is more
+ice at the south pole than at the north, according to all accounts. It
+is a place of great icebergs, immense floes and cold fogs. But there is
+land beyond the ice, I believe, and I am going to try to find it."
+
+"It will be a longer voyage than to the north pole," said Jack.
+
+"Jest de same," argued Washington, "de poles am at each end ob de
+world."
+
+"Yes, but we're quite a way north of the equator now, and we'll have to
+cross that before we will be half way to the south pole," explained
+Jack. "But I guess the _Porpoise_ can make good time."
+
+"If the engine behaves under water as well as it did just now, we'll
+skim along," said the professor.
+
+"And so you figure there's land down there to the south, do you?" asked
+old Andy.
+
+"I do," replied the inventor. "I can't prove it, but I'm sure there is.
+I have read all the accounts of other explorers and from the signs they
+mention I am positive we shall find land if we ever get there. Land and
+an open sea."
+
+"And other things as well," muttered Andy, yet neither he nor any of
+them dreamed of the terrible and strange adventures they were to have.
+
+The next few days were busy ones. Many little details remained to
+perfect in connection with the ship, and a lot of supplies and
+provisions had to be purchased, for the professor was determined to get
+all in readiness for the trip under the water. He believed firmly that
+his ship would work, though some of the others were not so positive.
+
+"We'll put her into the water to-morrow," announced the inventor after
+supper one night. "Everything is complete as far as I can make it, and
+the only thing remaining is to see if she will float, sink when I want
+her to, and, what is most important, rise to the surface again. For,"
+he added with a twinkle in his eye, "anybody can make a ship that will
+sink, but it isn't every one who can make one that will come to the
+surface again."
+
+"Golly! I hope dis chile ain't goin' to git in no subicecream ship
+what'll stay down under de water so de fishes gits him!" exclaimed
+Washington, opening his eyes wide. "Dat's worser dan freezin!"
+
+"Can't you swim?" asked Mark with a wink at Jack.
+
+"Co'se I can swim, boy. I can swim like a starfish, but I can't wif ten
+thousand tons of a subicecream ship on my back."
+
+"A sub-ice-cream ship is a new one," commented the professor with a
+smile. "It's a submarine, Washington."
+
+"I can't see no difference," persisted the colored man. "Subicecream am
+good enough for me."
+
+That night Mark and Jack were thinking so much of the proposed test of
+the ship the next day that they each dreamed they were sailing beneath
+the waves, and Jack woke Mark up by grabbing him about the neck during a
+particularly vivid part of the vision.
+
+"What's the matter?" inquired Mark, sleepily.
+
+"I thought the ship turned over and spilled me out and I was drowning,"
+explained Jack. "I grabbed the first thing I got hold of and it happened
+to be you."
+
+"Well, as long as you're safe you can go to sleep again," said Mark. "I
+dreamed I was chasing a whale with the _Porpoise_."
+
+The boys were up early the next morning, and found the professor and
+Washington before them. The inventor was inspecting the track which had
+been built from the shed down to the water's edge to enable the
+_Porpoise_ to slide into the ocean.
+
+With him were the two machinists, Henry Watson and James Penson. They
+had been busy since daylight making the ways secure.
+
+"She goes in after breakfast," announced the professor, "and I'm going
+to let you christen her, Washington."
+
+"Me? I neber christened a ship," objected the colored man.
+
+"Nothing like learning," remarked Mr. Henderson.
+
+"Has you got the bottle ob wine?" asked Washington.
+
+"I guess soda water will do," said the inventor. "Now look sharp, boys.
+Get your breakfasts and we'll see if the ship will come up to our
+expectations."
+
+No one lingered over the meal. When it was finished the professor gave
+Washington a few instructions about breaking the bottle over the nose of
+the _Porpoise_ as she slid down to the water, for there was no bow to
+such a queerly shaped vessel as the submarine.
+
+At last all was in readiness. The two machinists knocked away the last
+of the retaining blocks and eased the ship slightly down the
+well-greased timbers of the ways.
+
+"There she goes!" cried the professor. "Break the bottle, Washington!"
+
+"In de name ob de Stars an' Stripes, in de name of liberty, de home of
+the free an' de land ob de brave, I names yo' _Mrs. Porpoise_!" cried
+the colored man, but he was so long getting the words out, and so slow
+in swinging the bottle of soda, that the ship was quite beyond his reach
+when he had finished his oration. He was not to be outdone, however,
+and, with a quick movement he hurled the bottle at the moving ship. It
+struck the blunt nose squarely, and shivered to pieces.
+
+"Three cheers for de south pole!" yelled Washington, and the others
+joined in.
+
+The next instant the _Porpoise_ was riding the waves of the little bay,
+dancing about as lightly as a cork, though, from the nature of her
+construction, she was quite low in the water, only about three feet of
+freeboard showing where the platform was located.
+
+"Well, she floats, anyhow," remarked the professor. "Row out and fasten
+cables fore and aft," he went on, turning to the two machinists. In a
+few minutes the _Porpoise_ was fastened to a small dock with strong
+ropes the two young men had carried out to her in rowboats.
+
+"We will go aboard in a little while," the professor said. "I am anxious
+to see if she rides on an even keel and how the sinking tanks work."
+
+Aided by the boys, he and Washington carried on board a number of tools
+and appliances. Then, with the two machinists, they all descended into
+the interior of the craft through the small manhole in the middle of the
+deck or platform.
+
+Inside the _Porpoise_, the greater part of which was below the surface
+of the waves and consequently in darkness, the professor switched on the
+electric lights and then he proceeded to get up steam.
+
+The propelling power of the craft has already been described. In order
+to make the ship sink beneath the water all that was necessary was to
+incline the rudder and open certain valves in the four tanks, when the
+water, rushing in, would sink her. There was a tank on either side, and
+one each fore and aft. If it was desired to sink straight down all four
+tanks were filled at once. If the professor wanted to descend slanting
+either to the front or back, only one of the end tanks was filled,
+according to the direction desired. The deflecting rudder also aided
+greatly in this movement.
+
+To cause the ship to rise the tanks were emptied of the water by means
+of powerful pumps. The filling of the tanks, as well as the emptying of
+them, the starting or stopping of the engine that moved the boat, as
+well as the control of most of the important machinery on the craft
+could be accomplished from the conning or steering tower, as well as
+from the engine-room.
+
+There were numerous gages to tell the depth to which the ship had sunk,
+the steam pressure, density of the water, and other necessary details.
+
+There were dynamos to make light, motors to run the pumps, and a great
+storage battery, so that in case of a breakdown to the turbine engine
+the craft could be run entirely by electricity for a time.
+
+The cooking was all done by this useful current, and all that was
+necessary to make a cup of coffee or fry a beefsteak was to turn a small
+switch of the electric stove.
+
+The professor was busy over the machine for generating gas, that
+furnished the heat to create steam. Soon a hissing told that it was
+working. In a few minutes the hum and throb of the engine told that it
+was ready to start.
+
+"We are only going down a little way," the professor said, "and only
+going to travel a short distance under water for the first time. I think
+there is no danger, but if any of you want to back out, now is your
+chance."
+
+No one seemed inclined to withdraw, though Mark said afterward he
+thought Washington got as pale as it is possible for a colored man to
+get.
+
+"We will all put on life preservers," the inventor went on, "and one of
+you will be stationed near the emergency exit. In case anything goes
+wrong, and I cannot make the ship rise, by pulling the lever the top of
+the craft will be forced off, and, we can at least save our lives. I
+think we are all ready now. Mark, you clamp down the manhole cover, and
+Jack, after you close the conning tower station yourself at the
+emergency lever after we have donned the life preservers."
+
+The cork jackets were adjusted and Mark clamped the manhole cover on.
+The professor took one last look at the various levers and handles, and
+then turned the wheel that admitted water to all four tanks. There was a
+hissing sound as the sea water rushed in, and the _Porpoise_ gave a
+sudden lurch.
+
+Then they could all feel the submarine sinking. Down and down she went.
+Would she ever stop? Would the professor be able to raise her again?
+There were questions that troubled everyone.
+
+Down and down the craft sunk, until by the gage it was indicated that
+she was twenty feet below the surface. Then the professor shut off the
+inrush of water and the _Porpoise_ floated away below the surface of the
+waves.
+
+There was a clicking sound and all the lights went out. The boys and
+Washington gave a gasp of terror. What did the sudden blackness mean.
+
+"Open the side windows," called the professor's voice, and the two
+machinists obeyed. Heavy steel doors that covered plate glass windows in
+either side of the craft were pulled back, and a cry of astonishment
+broke from the boys.
+
+They looked out and saw staring in at them, so close it seemed that they
+could touch them, scores of fishes that looked in through the glass
+bull's-eyes.
+
+For the first time they realized that they were in the depths of the
+ocean.
+
+
+
+
+CHAPTER III
+
+RUNNING DOWN A WARSHIP
+
+
+"How do you like it?" asked the professor.
+
+"Great!" exclaimed Jack.
+
+"Fine!" cried Mark.
+
+"It am simply coslostrousness!" exploded Washington. "'Nebber in all my
+born days did I eber expansionate on such a sight!"
+
+"Wish I had a fishing pole and line," remarked Andy Sudds. "There's some
+pretty nice specimens out there."
+
+"You'll see better ones than those before we finish our trip to the
+pole," remarked the professor. "Now we will try moving forward. I am
+going into the conning tower."
+
+He turned on the lights once more, but the boys begged him to shut them
+off, as they could see out into the ocean when the interior of the ship
+was in darkness. So the professor obliged them.
+
+In the tower he switched on the powerful searchlight that illuminated
+the path in front of him. Then he started the engine, slowly at first,
+and gradually increasing the speed. The _Porpoise_ forged ahead, riding
+as evenly as an ordinary ship does on the surface.
+
+The professor steered her about in a large circle, bringing her back to
+the starting point. She worked as smoothly as if she had been used to
+under-water service for years.
+
+"Now," said the inventor, "we will see if we can go up to the surface
+again," and there came a little note of anxiety into his voice. He
+slowed down the engine and started the powerful pumps that were to empty
+the tanks. For a moment there was a feeling of terror in the hearts of
+all. Would the pumps work?
+
+Then, slowly but surely, those aboard the _Porpoise_ felt her beginning
+to rise. Up and up she went as the tanks were emptied and the ship
+lightened.
+
+Then, with a bounce like a rubber ball, the submarine shot upward to the
+surface and lay undulating on the waves caused by her emergence from the
+depths.
+
+"Hurrah!" shouted Jack. "We're all right!"
+
+"We shore am!" exclaimed Washington.
+
+"It's a success!" Professor Henderson almost whispered. "The pumps
+worked. The _Porpoise_ has fulfilled my greatest expectations!"
+
+Then he steered the ship back to the dock, where she was moored, and the
+adventurers disembarked.
+
+"One or two little details to attend to, and we'll be ready for the
+great trip," remarked the professor. "I want to give her a little harder
+trial before I trust her, though she seems to be first-rate."
+
+They all went back to the combined machine shop and cabin, where they
+had lived during the building of the submarine. Dinner was prepared and,
+after the meal the two machinists approached the professor.
+
+"I don't suppose you need us any more," remarked Henry Watson. "The ship
+is finished as far as we can do anything, and we may as well leave now.
+We have an offer to go to work in an electrical shop."
+
+"I haven't said much to you about my plans," the professor replied, "but
+if you would like to remain in my employ, I can promise you an
+interesting trip."
+
+"Thank you, but I prefer to work above ground," said James Pensen. "You
+have been very kind to us, and we would do anything we could for, but we
+don't want to take any long under-ocean trips if we can help it."
+
+"Very well," answered the professor, though he seemed disappointed. "I
+will pay you what I owe you and you can go."
+
+For some time after the departure of the two young machinists the
+inventor seemed worried.
+
+"Did you count on them staying with you?" asked Mark.
+
+"I rather hoped they would," replied Mr. Henderson. "We need two more
+hands if we are to make the trip. They need not be machinists, but we
+will have to have someone, and I don't like to get strangers. They might
+talk too much about the ship."
+
+At that instant there came a rap on the door. Washington answered it.
+
+"Yas sir, Perfesser Henderson done lib here," he replied, in answer to a
+question from some one. "But he am bery busy jest at de present
+occasioness an' he'll be most extremely discommodated if yo' obtrude yo'
+presence on him at de conglomeration ob de statutory limitations, which
+am to say right now. Come again!"
+
+"It's the same old Washington!" said someone outside, laughing heartily.
+"Just you tell the professor we want to see him most particular."
+
+At the sound of the voice the professor started and Mark and Jack
+wondered where they had heard it before.
+
+"Show the gentlemen in, Washington," called the inventor.
+
+"Dere's two ob 'em," objected the colored man.
+
+"Show them both in, then."
+
+Washington opened the door of the cabin, and in came two men, who
+seemed much amused over something.
+
+"What can I do for you?" asked the professor, in rather a sharp voice.
+
+"He don't know us either, Tom," remarked the taller of the two.
+
+"If it ain't Bill Jones and Tom Smith!" exclaimed Andy Sudds. "Wa'al
+I'll be horn swoggled. Where'd ye come from?"
+
+"Right from the farm," replied Bill. "And we've had a hard job locating
+you. I guess Washington didn't know us since we raised beards," and Bill
+stroked his wealth of brown whiskers.
+
+"And I guess we sort of fooled the professor," went on Bill, "eh, Tom?"
+
+"Right!" said Tom. "You see," he went on, "the farming business is
+almost over, as its coming on fall now, so Bill and I thought it would
+be a good time to hunt up the professor. We heard he was down in this
+neighborhood so we come by easy stages. We didn't have any time to stop
+and make our toilets, hence our beards."
+
+"You've come at the right time," remarked the inventor, as he came
+forward to welcome the two young men. "Do you remember the trip you made
+with me to the north pole?"
+
+"I guess we'll not forget it in a hurry," replied Bill.
+
+"That's what made us hunt you up," put in Tom. "We hoped you might have
+something similar on foot."
+
+"I have," answered the inventor.
+
+"What is it?"
+
+"A trip under the ocean!"
+
+For an instant the two young men hesitated. It was a new proposition to
+them. Yet they recalled that they had come safely back from the journey
+through the air.
+
+"Do you want to go along as part of the crew?" asked the inventor, after
+some further conversation.
+
+"You can count on me!" cried Bill.
+
+"And if Bill goes I'll go too!" exclaimed Tom.
+
+"Under the seas or over the seas, it'll be all one to us if Professor
+Henderson sails the ship!" went on Bill. "We'll go!"
+
+"Good!" ejaculated the professor. "You certainly came at just the right
+time."
+
+As Tom Smith and Bill Jones were hungry a hasty meal was prepared for
+them, during the eating of which they told of their experiences since
+landing from the airship. They had been on a farm until fired with a
+desire to go roving once more.
+
+For the next few days the professor, the boys, and the other four were
+busy making some improvements to the _Porpoise_. Tom and Bill were much
+astonished at their first sight of the queer craft, but they soon became
+accustomed to her, and said they preferred her to the airship.
+
+"To-morrow we are going on a little longer trip than our first trial,"
+announced the inventor one evening. "We will be gone all day if nothing
+happens to make the stay more lengthy," he added grimly. "So,
+Washington, put plenty to eat aboard."
+
+A little later, when supplies had been put on the _Porpoise_, and the
+machinery well overhauled, the professor explained that he intended
+making a trip, entirely under water, from the dock in the cove to a
+point off the Massachusetts coast and return.
+
+Early the next morning all were aboard. To each one was assigned a
+particular station. Washington, with Mark as an assistant, was in the
+engine-room. Jack was to watch the various gages and registers to give
+warning of any danger. The professor, of course, would be in the conning
+tower and operate the craft. Andy was to be with him, to watch out, with
+his sharp eyes, for any danger that might loom up in the path of the
+searchlight. Tom and Bill were to be ready to help where needed.
+
+With a hissing sound the water filled the tanks and the _Porpoise_ sunk
+beneath the waves. The engine that worked the endless screw was
+started, and the threads, working on the water cable, shot the boat
+ahead.
+
+"We're off!" yelled Washington.
+
+About sixty feet below the surface the craft was sent along. Mile after
+mile was covered as shown by the patent log. The lights were turned off,
+and through the thick plate glass windows the strange inhabitants of the
+sea were observed.
+
+"I think I'll go a little nearer the surface," said the professor to
+Andy. The inventor started the pumps that emptied the tanks. The craft
+rose slightly.
+
+"Quick! Stop her!" shouted the old hunter, grasping the captain's arm.
+
+Something black, like a grim shadow, loomed up in the dull glare of the
+searchlight.
+
+"What is it?" cried the professor.
+
+"We're goin' to hit somethin' hard!" yelled Andy.
+
+"It's the hull of a ship!" exclaimed the inventor as he jammed the
+reversing lever hard over.
+
+It was too late. The next instant the _Porpoise_, with a shock that made
+her shiver from stem to stern, collided with the steel side of a small
+warship.
+
+
+
+
+CHAPTER IV
+
+IN THE MIDST OF FIRE
+
+
+"Pull the secondary emergency lever!" cried the professor through the
+speaking tube to Washington. "We must reach the surface at once!"
+
+"Are we damaged?" asked Andy, scrambling to his feet, for the shock had
+knocked him down. The professor had not fallen because he clung to the
+steering wheel.
+
+The ship gave a sudden lurch.
+
+"We're sinking!" cried Bill, rushing to the conning tower from the
+engine-room.
+
+"That's only the action of one of the emergency levers," said the
+professor calmly. "It forces compressed air into the tanks the more
+quickly to empty them of water. I think we are safe."
+
+"What is it?" asked Mark, as, followed by Jack, he came forward.
+
+"We tried to do the torpedo act to one of Uncle Sam's ships," explained
+Andy.
+
+The electric lights had been switched on, and, with the _Porpoise_
+flooded with the bright beams, those on board waited anxiously for what
+was to happen next.
+
+Suddenly an upward motion was experienced. The next instant the craft
+bounced out of the water and fell back in a smother of foam, shaking and
+shivering, alongside a small armored warship that was anchored about two
+miles and a half from shore.
+
+"Open the manhole," commanded Mr. Henderson.
+
+Mark sprang up the iron ladder that led to the opening in the deck of
+the _Porpoise_ and threw back the cams that held the heavy iron in
+place. Then he swung the cover back and stepped out on the small
+platform, followed by the professor, Andy and Jack. They looked up to
+find themselves observed by a curious throng that crowded to the rail of
+the warship.
+
+[Illustration: A CURIOUS THRONG CROWDED TO THE RAIL OF THE
+WARSHIP.--_Page 28._]
+
+"What are you trying to do? Ram me with a new-fangled torpedo?" asked an
+angry voice, and a man in a gold laced uniform, who, from his importance
+plainly showed himself to be the captain of the ship, shook his fist at
+Mr. Henderson.
+
+"I might ask what right your ship has to get in my path," replied the
+inventor. "It was all an accident."
+
+"Mighty queer," muttered the naval commander. "Looks very suspicious.
+How do I know but what you're a torpedo from some foreign nation?"
+
+"Because this is not a torpedo," replied Mr. Henderson. "It is a new
+submarine boat of my invention, and I was giving it a trial spin."
+
+"I guess you'd better come aboard and do your explaining," went on the
+captain. "I don't like the looks of things. Lower a boat!" he shouted,
+"and bring those chaps to my cabin. I want to question them."
+
+It did not suit Professor Henderson to have his plans upset in this
+fashion. Nor did he care to give a detailed description of his ship to
+officers of the war department. He had many valuable inventions that
+were not patented. So he determined to outwit the pompous commander of
+the cruiser.
+
+The noise made in preparing the small boat for lowering over the side of
+the big ship could be plainly heard.
+
+"Go below, all of you, and as quietly as you can," whispered Mr.
+Henderson.
+
+Andy, Mark and Jack obeyed. At that instant the side of the warship was
+almost deserted, for the sailors who had gathered to observe the
+_Porpoise_ had gone to lower the small boat.
+
+No sooner had Jack, who was in the rear, disappeared through the manhole
+than the professor, with a quick jump, followed him.
+
+"Here! Come back!" shouted the warship's captain as he saw Mr.
+Henderson's head disappearing from view. "Come back I say!"
+
+But with a quick movement the inventor pulled down the manhole cover and
+clamped it. Then he sprang to the conning tower, and, with a jerk,
+opened the levers that admitted water to the tanks. The _Porpoise_ began
+to sink slowly, and then more suddenly, so that, in less than a minute,
+she was out of sight beneath the waves, and the angry, gold-laced
+captain was staring in wonderment at the place where the submarine had
+been. The spot was marked only by a few bubbles and some foam.
+
+"I guess he'll wait some time for an explanation," spoke Mr. Henderson,
+as he started the big screw and sent the _Porpoise_ ahead at a swift
+pace.
+
+"That was rather a narrow escape," observed Jack, standing at the foot
+of the conning tower stairs and talking to Andy and Mr. Henderson, who
+was steering.
+
+"It certainly was," agreed the professor. "I have not yet become used to
+seeing things very far ahead in the dimness caused by being under water.
+But we'll soon get used to it. Luckily, the _Porpoise_ was not damaged
+by the shock."
+
+For several hours the _Porpoise_ was kept on her course. She behaved
+handsomely, and nothing excepting slight and easily remedied defects
+were found. The professor steered well out to sea, increasing both the
+forward speed and the depth to which the vessel sank. Presently the
+craft came to a stop with a little jolt.
+
+"What's the trouble?" asked Mark, somewhat alarmed.
+
+"Nothing at all," replied the professor with a smile, as he stepped out
+of the conning tower and entered the engine-room. "I thought it was time
+for dinner so I stopped the ship. We are now resting on the ocean bed,
+about half a mile below the surface. Look!"
+
+As he spoke he slid back the slides covering the plate glass windows.
+The boys saw that the ship rested in the midst of an immense forest of
+sea weed. Some of the stalks were as large around as trees. In and out
+among the snake-like, waving branches swam big fishes. It was a weird,
+but beautiful sight.
+
+"Come, Washington, serve dinner," ordered Mr. Henderson, and the colored
+man soon had a good meal prepared. Few repasts have been eaten under
+such strange circumstances.
+
+Desiring to be back at his secluded dock by nightfall, Captain Henderson
+soon started the _Porpoise_ up again. Without any accidents the return
+trip was made and by nine o'clock the _Porpoise_ rode safely at the
+dock where she had been launched.
+
+The night was spent in the cabin on shore. Early the next morning Mr.
+Henderson paid a visit to the ship, to make a thorough examination by
+daylight, and see if the craft had suffered any damage.
+
+"I think you and Mark will have to make a trip to town," he said to Jack
+at the breakfast table. "I need a new monkey wrench and some other tools
+and some small pieces of machinery. I'll give you a list of them, and
+you can bring them back in a valise, for they will be quite numerous."
+
+After the meal the inventor made a record of what he needed and the boys
+started off.
+
+"In case the machine shop does not have everything and you have to wait
+for something, you had better stay in the town all night," the captain
+of the _Porpoise_ said. "It is quite a long trip and I don't want you
+traveling after dark. Put up at the hotel if you are delayed."
+
+Provided with money for their purchase, and a large valise in which to
+carry them, the boys started off. They had to walk two miles to where a
+trolley line was built that ran to the town of Easton, where they were
+to get the tools and parts of machinery.
+
+They made the trip safely and without incident. When they gave the
+machinist, to whom they had been directed by Mr. Henderson, the list of
+the things needed, the man looked puzzled.
+
+"I'll have to make one piece," he said. "You'll have to wait for it.
+Can't promise it before to-morrow morning about eight o'clock."
+
+"That will be all right," remarked Mark. "We'll call for it then."
+
+So, bearing in mind Mr. Henderson's instructions, the boys engaged a
+room at the hotel, which was quite a large one, for Easton was a
+favorite summer resort and the town was filled with visitors. The lads
+strolled about the town, had their dinner, and then went for a bath in
+the surf. They retired early, for they were tired.
+
+In the middle of the night Mark began to dream that he was on board the
+_Porpoise_ and that the submarine blew up. There was a loud noise, he
+saw a bright flash of flame, and saw rolling clouds of smoke. So vivid
+was the vision that he thought he tried to leap out of the boat, and
+awoke with a jump, to find Jack shaking him.
+
+"What's the matter?" inquired Mark.
+
+"The hotel's on fire!" shouted Jack.
+
+Mark sprang out of bed and with Jack rushed to the window, for their
+room was filled with thick smoke. They could see the dull glare of
+flames, which every moment were becoming brighter.
+
+The next instant a loud explosion shook the building. It swayed and
+seemed likely to topple over. Outside the boys could hear excited shouts
+and the puffing and whistling of fire engines.
+
+"Quick! Run!" yelled Mark. He opened the door leading into the corridor,
+but was driven back by a rush of flames and smoke that almost stifled
+him.
+
+"We must try the fire escape!" shouted Mark.
+
+"Don't forget the valise with the tools;" exclaimed Jack, and Mark
+hastened to where he had placed it under the bed.
+
+Then the two boys rushed to the balcony on which their front windows
+opened, and whence the fire escapes led down to the streets. The lads
+had only time to slip on their coats, trousers, shoes and caps.
+
+As they were preparing to clamber down the iron ladders they heard
+someone on the balcony next to them shout:
+
+"Here, you boys! Stop! I want you!"
+
+
+
+
+CHAPTER V
+
+A GRAVE ACCUSATION
+
+
+"We haven't time now!" yelled back Mark, looking in the direction of the
+voice, and seeing a short, stout man, who appeared greatly excited.
+
+"Stop or I'll shoot!" the man exclaimed.
+
+"The fire must have made him crazy," said Jack. "Go on, Mark, it's
+getting hot up above!"
+
+Mark did not linger on the ladder and soon the two boys were in the
+street, surrounded by an excited crowd.
+
+"Are you hurt?" asked several.
+
+"I guess not," replied Mark. "What caused the fire?"
+
+"Some sort of an explosion," answered a policeman. "Part of the hotel
+was blown up. If you boys wish you can go to a station house where
+you'll be comfortable until morning."
+
+"I guess we will," said Mark.
+
+They started to work their way through the crowd but did not notice that
+the strange man followed them. The fire was now burning fiercely, and
+once they had gotten clear of the press the lads halted to look at the
+spectacle.
+
+The hotel was now a mass of flames and the firemen were kept busy. What
+with the puffing of engines, the whistling of the steamers, the roar of
+the flames, and the shouts of the crowd, pandemonium reigned.
+
+The boys watched the fire for some time. Gradually the flames came under
+the control of the men and the leaping tongues died out.
+
+"I guess we'd better go to the police station," suggested Jack.
+
+Mark agreed this would be a good thing to do, as both of them felt
+rather chilly in the night air with only half of their clothes on. They
+inquired their way of the first policeman they saw, and he volunteered
+to escort them.
+
+"Sure an' you'll have plenty of company," he said. "The hotel was full
+an' the people have no place to go except to the lock-up. Some swells
+will be glad to take a place behind the bars to-night I'm thinkin'. I
+wonder how some of those English aristocrats will like it?"
+
+"English aristocrats?" repeated Jack. "Are any here?"
+
+"Sure. There's a lot of them burned out. Lord Peckham was stoppin' at
+the hotel with a big crowd of people, an' their apartments was all
+destroyed. Some of 'em went to the police station."
+
+The boys followed their uniformed guide through the streets of Easton,
+and were soon at the station house. There they were received by the
+sergeant in charge, while the matron gave them each a cup of hot coffee,
+a large pot of the beverage having been brewed.
+
+"I'll have to give you boys one bed between you," said the sergeant.
+"We're rather crowded for room to-night."
+
+"Anything will do us," said Jack with a laugh.
+
+Just then there was some excitement at the entrance of the police
+station.
+
+"I tell you they're in here! I will see them!" a voice exclaimed. "I
+want them arrested at once!"
+
+"Go easy now," counseled the doorman as he tried to hold back a short,
+stout, excited man who was pushing his way into the station.
+
+"There they are!" exclaimed the man, pointing to Jack and Mark.
+
+"Why those boys are from the burned hotel," said the doorman.
+
+"I know it! They are the very ones I want!"
+
+"What do you of us?" spoke up Mark. He recognized the man as the one who
+had called to him as he and Jack were escaping.
+
+"I charge you with being sons of James Darrow, the notorious English
+anarchist!" cried the little man, pointing his finger at the boys, "and
+I accuse you of trying to kill Lord Peckham with a bomb, the explosion
+of which set fire to the hotel!"
+
+For a moment the surprising charge so astonished every one that not a
+word was said. Then the little man, advancing toward the boys went on:
+
+"I arrest you in the name of His Royal Highness, Edward VII, King of
+England, Scotland and Wales."
+
+He threw back the lapel of his coat and showed a badge.
+
+"King of England, Scotland and Wales, is it!" exclaimed the doorman with
+a twinkle in his eye. "An' why didn't ye say Ireland into the bargain."
+
+"Ireland, of course," went on the little man. "I'm an officer of His
+Most Gracious Majesty," he added, "and I demand the assistance of the
+United States authorities in general and the police of Easton in
+particular in taking these desperate criminals into custody!"
+
+"Hold your horses," advised the desk-sergeant. "Those boys are not
+liable to run away. They're to stay here over night, and if you have any
+charge to make against them why you'll have to come and see the judge
+in the morning."
+
+"But they are sons of an anarchist! They are anarchists themselves!"
+exclaimed the man, "I must arrest them!"
+
+"You're not going to arrest anybody," said the sergeant, "until you get
+a warrant from the judge. This isn't England."
+
+"Then I'm going to stay with these boys the rest of the night," insisted
+the man. "I can't take any chances on their giving me the slip."
+
+"This place is going to be crowded with people from the burned hotel,"
+objected the sergeant. "There will be no room for you. Besides, how do I
+know these boys are anarchists?"
+
+"Look in their valise," cried the stranger. "It is filled with bombs."
+
+"You can't look in this satchel," exclaimed Jack, for he remembered the
+valise contained parts of the professor's secret machines.
+
+"What did I tell you?" cried the Englishman with triumph in his tones.
+"They are the guilty ones. They are afraid to open their valise."
+
+"We are, but not because it has bombs in it," said Mark. "It has parts
+of an unpatented machine and the owner does not want any one to see
+them," for Mark remembered Mr. Henderson's strict injunctions to let no
+one but the mechanist to whom they had gone catch a glimpse of the
+parts that were to be duplicated. The machinist was sworn to secrecy.
+
+"It's none of our affair," said the sergeant, though he seemed a little
+impressed by the Englishman's words and the reluctance Mark and Jack
+showed to letting the valise be opened. "The boys will be here until
+morning, and then you can see the judge. Now you'll have to get out. You
+boys get to bed."
+
+Muttering threats, the stranger went from the station house, and Mark
+and Jack, in response to a nod from the doorman, followed him upstairs
+to a part of the police station used to detain witnesses. They were
+shown to a small room with a single bed.
+
+"Are ye really anarchists?" asked the doorman.
+
+"Not a bit," replied Jack, and he told as much of their story as he
+dared.
+
+"I was kind-of hopin' ye was," said the officer with a twinkle in his
+eye. "It wouldn't do any harm to scare that uppish Englishman a bit.
+Sure he an' his kind have done enough to poor old Ireland."
+
+"I'm sorry we can't oblige you," said Mark with a laugh.
+
+"I guess ye're all right," went on the doorman. "I hope ye sleep good
+the rest of the night."
+
+Then he left them alone. What with the excitement of the fire and the
+startling accusation against them, the boys' brains were too excited to
+let them sleep much. They had a few fitful naps throughout the remainder
+of the night.
+
+It was just getting daylight when Mark was awakened by some one shaking
+him.
+
+"What is it?" he asked. "Another fire?"
+
+"Not this time," replied a voice, and Mark, now that his eyes were fully
+opened, saw the doorman bending over him.
+
+"What's the matter?" asked Jack waking up in his turn.
+
+"Easy!" exclaimed the doorman in a whisper. "I happened to think ye
+might want to be leavin'."
+
+"Leaving?" asked Mark in bewilderment.
+
+"Yes. Ye know that Englishman is liable to be back any minute, an' he
+may make trouble for ye. I know ye're innocent lads, an' I'd hate to see
+ye mixed up in a mess with that fellow. So I slips up here early, an' ye
+can leave by the back door if ye want to, an' the officer of His
+Imperial Majesty, King Edward VII, will never know a thing about it."
+
+"It looks like running away," objected Jack.
+
+"Sure there's no charge agin ye," went on the doorman. "Ye're free to
+come an' go as far as we're concerned, an' ye'd better go whilst ye have
+the chance."
+
+Jack reflected. It was true that the charge of the Englishman, baseless
+as it was, might make trouble for them, and cause them endless delays in
+getting back to Professor Henderson. Suddenly Jack made up his mind.
+
+"Come on Mark," he said.
+
+
+
+
+CHAPTER VI
+
+ON A RUNAWAY TROLLEY
+
+
+"Are you going to leave?" asked Mark.
+
+"Certainly. There is no use staying here and getting mixed up in
+something that Englishman thinks we have done. It's easier to go away
+quietly and let him find out his mistake."
+
+"All right," agreed Mark. "I wonder who he is, anyhow?"
+
+"He thinks he owns the earth, whoever he is," returned Jack.
+
+"He's some sort of a special detective traveling with Lord Peckham's
+party," explained the doorman. "He told us a lot about himself last
+night after you boys went to bed. He came back to inquire how early the
+judge would be here.
+
+"He went on to tell how some English anarchists have vowed to kill Lord
+Peckham because he foreclosed a lot of mortgages on some poor people in
+Ireland where he owned property," added the doorman. "There was some
+sort of explosions in the hotel, near where Lord Peckham had his rooms.
+Maybe it was a bomb and, maybe ag'in it was only the boiler. Anyhow,
+this detective jumped to the conclusion that anarchists had done it, and
+he thinks you are responsible. But you'd better be goin' now. It's
+gettin' daylight."
+
+So Mark and Jack, with what scanty clothes they had, and carrying their
+valise, went quietly out of the back door of the police station.
+
+"We'd better go to the machine shop for the rest of the stuff,"
+suggested Mark, "and then we can take the first trolley we see and get
+back to the professor."
+
+Through quiet side streets the boys made their way toward the machine
+shop. They were somewhat amused to think how they had fooled the
+detective, but they would not have felt so jolly had they seen the
+roughly dressed man who had darted after them as soon as they left the
+police station.
+
+"I'll get you yet," the man muttered. "You needn't think to escape with
+the aid of these bloomin' American police."
+
+The lads found the machinist just opening his shop though it was quite
+early. The pieces of apparatus were finished and, after paying for them
+Mark put the parts in the valise.
+
+"Quite a fire in town," observed the machinist.
+
+"Yes," answered Mark, not wishing to get into a long conversation.
+
+"Heard the hotel was blowed up by anarchists and that the police are
+after 'em," proceeded the man.
+
+"I believe I did hear something like that," admitted Mark. "I guess
+we'll be going."
+
+He signalled to Jack, and the two hurried out of the shop. As they did
+so, the trampish-looking man glided from behind a tree where he had been
+hiding and took after them.
+
+"Say," exclaimed Jack, "I forgot we haven't had any breakfast yet."
+
+"That's so," said Mark, rubbing his stomach and making a wry face.
+
+Near by was a bakery, and there the lads got some coffee and rolls which
+tasted fine. When they finished their simple meal a trolley came past
+and they ran to catch it. So did the man who had been following them,
+but this person bore no resemblance to the spruce little detective who
+had wanted to arrest the boys.
+
+"A couple of hours now and we'll be back at the cabin," spoke Mark. "My,
+but I must say we have had strenuous times since we started away!"
+
+There were few passengers on the trolley so early in the morning and not
+many stops to make, so the motorman turned on the power full and made
+the vehicle speed along.
+
+Mile after mile was covered and finally the car reached the top of a
+long hill. At the foot of this the line came to an end, and the boys had
+a two mile tramp before them to reach the lonely spot where the
+_Porpoise_ was docked.
+
+Down the hill the car started. The motorman shut off the electricity and
+let the vehicle run by its weight.
+
+Faster and faster it ran, the dust flying in a cloud about it.
+
+"Better put the brakes on a bit," called the conductor. "It's gettin'
+kinder speedy, Hank!"
+
+The motorman twisted the handle. There was a grinding noise as the shoes
+took hold on the wheels. Then a chain snapped and the car seemed to leap
+ahead.
+
+"The brake's busted! I can't stop the car!" yelled the motorman.
+
+Vainly he twisted at the handle. Then, seeing he could not stop the
+trolley car he made a desperate jump off the vehicle and landed in a
+heap on the side of the road, rolling over and over.
+
+"Reverse the current!" cried one of the passengers, to the conductor.
+"That ought to stop her!"
+
+The conductor made his way to the front platform and turned the
+reversing lever. Then he applied the current. But it was no use. With a
+blinding flash and a report like that of a gun a fuse blew out, and that
+crippled the car completely so far as the electric current was
+concerned.
+
+"Everybody jump!" cried the conductor. "There's a curve at the foot of
+the hill, and we'll all be killed if we stay on!"
+
+One by one the passengers leaped from the car. Several were badly hurt
+by the falls they got. Meanwhile the trolley was tearing down the hill
+at a terrific rate of speed.
+
+"Shall we jump?" asked Mark of Jack.
+
+"We'll be killed if we do," was Jack's answer.
+
+"And we'll be killed if we stay aboard," said Mark.
+
+"Not if I can help it," cried Jack as he started for the rear platform.
+
+"What are you going to do?" asked Mark.
+
+"Put on the other brake. They never thought to try this one! Maybe it
+will work and stop the car!"
+
+Then Mark saw what Jack was up to and went to help him. The shabbily
+dressed man seemed undecided what to do. He stood up, holding to the
+straps to prevent himself from being tossed from side to side as the
+runaway trolley swayed. He watched the boys curiously.
+
+The lads, reaching the rear platform, twisted at the brake handle with
+all their strength. They could feel that the chain was still intact. But
+would the shoes grip the wheels with force sufficient to stop the car?
+
+There was a shrill screech as the brakes were applied by the boys. With
+all their might they turned the handle, winding the chain up tighter and
+tighter. At last they could not budge it another inch. Then they waited
+anxiously.
+
+The car never slackened its speed. So great was the momentum that had
+both sets of brakes been in working order it is doubtful whether they
+would have stopped the vehicle. The speed was so great now that one of
+the journals became hot and the oily waste that was packed in it caught
+fire, making what railroad men term a "hot box".
+
+"I guess we're done for," groaned Mark.
+
+"We certainly haven't checked the speed any," Jack admitted. "But wait a
+minute."
+
+He began stamping on the floor of the platform.
+
+"What you doing?" cried Mark, for he had to shout to make his voice
+heard above the roar and rattle of the car.
+
+"Putting on the sand," replied Jack, as he kicked at the plunger which,
+being depressed, let a stream of fine gravel out on the rails. "The
+wheels are gripped I think, and are slipping on the rails. This may help
+some."
+
+"Let me give you a hand," exclaimed a voice, and the boys turned to see
+the shabby man standing with them on the platform. He grasped the brake
+handle, and gave it an additional turn. His strength seemed remarkable
+for so small a man.
+
+The speed of the car was checked a little, but the vehicle was still
+speeding along at a rate that would soon bring it to destruction if not
+halted before the curve was reached.
+
+"That's a little better," observed Mark. "It's a good thing you were
+here."
+
+"Good for me, not so good for you," said the man with a peculiar smile.
+
+"What do you mean?" asked Mark.
+
+"I mean that I shall have to place you under arrest for attempting to
+assassinate Lord Peckham!" exclaimed the man. "I am Detective Ducket, of
+Scotland Yard!"
+
+He stripped off a false beard he had donned, and threw back his coat,
+displaying his shield. He was the same man who had attempted to arrest
+the boys in the police station at Easton.
+
+"I've got you just where I want you now," Detective Ducket went on.
+"There are none of those blooming American police to interfere."
+
+The next instant the car gave a sudden lurch. Then it seemed to rise up
+in the air. Jack felt himself flying through space, and he observed
+Mark, who was clinging to the valise, following him.
+
+There was a terrific crash, a ripping, tearing splintering sound, and
+the runaway trolley smashed into a big oak tree at the foot of the hill.
+The vehicle had completely jumped the track at the sharp curve.
+
+Jack's eyes grew dim, and he seemed to be sinking down in some dark pool
+of water. He heard a splashing beside him and began to strike out,
+trying to swim. He seemed to be choking. Then the blessed air and
+daylight came to him, and he found he was floating on the surface of a
+pond.
+
+He dashed the water from his eyes and saw, over on the bank, the wreck
+of the trolley. Then he noticed that Mark was swimming beside him.
+
+"What happened?" asked Jack.
+
+"A little of everything," panted Mark. "Lucky we weren't killed. We must
+have been flung off the rear platform into this duck pond."
+
+The boys soon made their way to shore, unhurt except for the wetting.
+The fall into the water had saved their lives.
+
+"Where's the valise of machinery?" asked Jack.
+
+"There it is," answered Mark pointing to where it had fallen at the back
+of the pond.
+
+"And what became of Detective Ducket?"
+
+"He's here, at your service!" exclaimed a voice. "Consider yourselves
+under arrest and don't you dare to leave this place without me."
+
+The boys looked in the direction of the sound and saw the English
+officer lying on the grass not far away. He seemed in pain, but had
+raised himself on his elbow and was pointing his finger sternly at the
+boys.
+
+
+
+
+CHAPTER VII
+
+OFF FOR THE SOUTH POLE
+
+
+"Are you hurt?" asked Jack.
+
+"I think my leg is broken, but otherwise I'm not damaged," replied the
+detective. "Even if I am disabled, it makes no difference, you are my
+prisoners. I command you to stay here until help comes."
+
+The boys did not know what to do. They did not like to see even an enemy
+suffer, but, at the same time, they knew he had no right to arrest them.
+
+"Here comes a wagon," said Mark, catching the sound of wheels.
+
+"Well, fo' de land sakes! Gollyation! What terrible catafterme hab
+occurred in dis unapproachable manner?" a voice demanded.
+
+"It's Washington!" cried Mark, as he saw Professor Henderson's colored
+assistant driving along the road.
+
+"Dat's who it am!" exclaimed Washington as he noticed the boys. "My! My!
+But am you boff dead?"
+
+"No, only one of us," said Mark with a laugh, as he and Jack ran toward
+the wagon.
+
+"Ha! Ha! Dat's one ob yo' jokes," said Washington. "But hurry up, boys.
+De perfessor he done sent me to meet you. He reckoned you'd becomin'
+ober on an early trolley. He's in a hurry to git away."
+
+"Don't you boys dare to leave!" exclaimed Detective Ducket.
+
+"Who's dat?" asked Washington.
+
+"Never mind," said Mark. "He was hurt in the trolley smash, but not
+badly. We'll send help, from the first farm house we come to. Come on,
+Washington, we'll go with you."
+
+The boys jumped into the wagon, and Washington started off. He explained
+that the inventor was anxious to make a start that day, as there would
+be an unusually high tide which would be followed a little later by a
+low one, and that would make it difficult to cross the harbor bar.
+
+"So I hired dis wagon an' come after you," said the colored man.
+
+At the first house they came to the boys stopped and told about the
+accident. The farmer agreed to go and get the detective and the others
+who were hurt and take them to a hospital.
+
+"I guess we're rid of that detective now," observed Jack, as they
+started off again.
+
+"Yes, but we're getting away under a cloud on our characters," said
+Mark. "I'd like to stay and see the thing through, if we had time."
+
+"But we can't, and there's no use worrying over it," spoke Jack.
+
+In a short time they were at the inventor's cabin, and related to Mr.
+Henderson all that had occurred.
+
+"Well I guess your detective friend will have a hard time to find you in
+a few hours," said the old man. "We start on our trip for the south pole
+this evening."
+
+There were busy times for the next few hours. Many supplies had to be
+placed on board, and, while the boys, with Tom and Bill, saw to this, the
+professor and Washington were occupied with putting the last touches to
+the submarine boat's machinery.
+
+Most of the supplies from the cabin were placed in the _Porpoise_,
+including food and clothing and a good quantity of minerals that, with
+sea water, generated the gas that made steam.
+
+An early supper was made on shore, as the professor said they might be
+so busy for the first few hours of the starting trip that they would get
+no chance to eat. Then the cabin and buildings where the submarine had
+been built, were securely fastened.
+
+"I guess we're all ready," announced the professor, taking a last look
+around.
+
+One by one they went aboard the _Porpoise_ crawling down through the man
+hole. The inventor was the last one to enter. He clamped the cover on by
+means of the cam levers and switched on the electric lights. Then he
+took his place in the conning tower with Andy Sudds.
+
+"Forward, to the South Pole!" exclaimed Mr. Henderson.
+
+With a turn of his wrist the inventor started the engines. The big screw
+in the shaft revolved, pulling the water in at one end of the craft and
+sending it out in a swirling stream at the other. The trip was fairly
+begun.
+
+For several miles the _Porpoise_ glided along on the surface of the
+ocean. It was a calm evening, and the boys down in the cabin of the
+craft could look into the reflecting mirrors on the wall, which were
+connected with observation magnifying glasses in the conning tower, and
+view what was going on, though their heads were below the surface of the
+sea.
+
+As it grew darker the view of shore and water faded away. The engine
+kept up its speed with Washington to see to it every now and then,
+oiling the bearings, some of which did not run quite smoothly because of
+their newness.
+
+"I'll send her down a bit now," observed the professor. "I don't want to
+run into any more warships or scare the crews by making them think we
+are a foreign torpedo boat."
+
+He opened the sea cocks in the ballast tanks and soon the _Porpoise_
+sunk about two hundred feet beneath the waves. The craft, which had been
+pitching and tossing under the influence of a ground swell, became more
+steady and quiet once it left the surface.
+
+The searchlight in the conning tower was turned on, and in the glare of
+it Andy and the professor were able to steer properly, aided by the
+compass which gave them the true southern course.
+
+It was now quite dark. Additional electric lights were switched on in
+the cabin, engine and dining room. Andy came out of the conning tower
+and announced that Captain Henderson wanted Washington to get supper.
+
+All the cooking was done by electricity, and, in addition to a supply of
+the usual and ordinary kinds of food, there was a big lot of patent
+condensed victuals to draw on. Soup, broiled steak, potatoes, hot
+biscuits, rice pudding and coffee made up the repast which was enjoyed
+by all.
+
+Toward the close of the meal Professor Henderson began to sniff the air
+of the cabin.
+
+"What's the matter? Do you smell a storm brewing?" asked Andy.
+
+"No, but the air is not as fresh as it should be," replied the inventor.
+"Washington, release a little more of the supply from the compression
+tanks."
+
+The ship, which had been left to steer itself automatically while the
+professor was absent from the conning tower, was moving along at about
+half speed. The gage showed they were going at twenty miles an hour, and
+were three hundred feet below the surface.
+
+"Washington and I will share the first night's watch between us," said
+the inventor, after the supper things had been cleared away. "There will
+not be much to do, as the ship will steer automatically in whatever
+direction I set her. Still I want to see how she behaves. The rest of
+you might as well go to your bunks."
+
+The two boys were especially glad of a chance to go to bed, as they had
+had but little sleep the night before on account of the fire. So they
+lost no time in undressing and rolling up in the blankets, for it was
+quite cool so far down under the water.
+
+"Well, we've slept on the earth, above the earth and now we're under the
+waters," observed Jack.
+
+"There's only one place more to spend your time taking a snooze," said
+Mark.
+
+"Where's that?"
+
+"Inside the earth."
+
+Then they fell asleep. During the night and the next day the _Porpoise_
+forged on underneath the waves. Washington relieved Mr. Henderson in the
+conning tower and reported the machinery to be working well.
+
+"Keep her headed due south," was the order of the inventor, and the
+colored man did so.
+
+It was about four o'clock one morning that Washington felt a slight jar
+to the submarine.
+
+"Hope we ain't goin' to hit no more battleships," he said.
+
+He glanced at the speed-indicating gage. To his surprise it stood at
+zero. The craft was not moving forward a foot! Yet the engines were
+going at half speed!
+
+In great alarm Washington shut off the power and ran to acquaint
+Professor Henderson with the news.
+
+"Suffin's ketched us!" cried the colored man.
+
+"Nonsense!" said the inventor, yet he seemed alarmed as he slipped on
+his clothes and hastened to the conning tower.
+
+He peered ahead along the path of water illuminated by the glare of the
+searchlight, but nothing was to be seen. Then he started the engine,
+increasing the speed gradually until the big screw in the shaft revolved
+more than one thousand times a minute. Still the _Porpoise_ never
+stirred. She remained in the same position, as if some giant hand
+grasped her.
+
+"Reverse the engine," said the professor.
+
+Washington did so. To the surprise of both of them the ship shot
+backward like a frightened crab.
+
+"Now forward!" exclaimed the old inventor.
+
+But this time the _Porpoise_ did not move. It was as if she was up
+against a stone wall.
+
+"What's the matter?" asked Mark, who had been awakened by the excitement
+on board.
+
+"I do not know," replied Mr. Henderson gravely. "Something mysterious
+has occurred. We can go no further!"
+
+
+
+
+CHAPTER VIII
+
+ASHORE IN THE DARK
+
+
+"Stop the engine," the captain commanded after he had peered through the
+lens in the conning tower for some time. "We must see what is the
+matter."
+
+He glanced at the depth gage and noted that they were now four hundred
+feet below the surface. Then he consulted some charts.
+
+"There is a depth of one thousand feet about here," he remarked. "Lower
+the ship, Washington. Let us see if by getting on the ocean bed we can
+get away from this obstruction."
+
+The colored man opened wider the sea cocks by which the tanks were
+filled. The increased ballast sunk the _Porpoise_ still lower, and, in a
+few minutes a slight jar told the navigators that they were on the
+bottom of the ocean.
+
+"Now we will see if we have cleared the obstruction," said the
+professor.
+
+He started the big screw to revolving, but the ship did not move. It
+shivered and trembled throughout its length but remained stationary.
+
+"Maybe dar's a debil fish what hab circumulated dis ship in de exteror
+portion ob his anatomy," suggested Washington, rolling his eyes until
+only the whites were visible.
+
+"I presume you mean that a giant squid or cuttle fish has attacked us,"
+spoke the professor.
+
+"Yas, sir," replied Washington.
+
+"That's nonsense," went on the inventor. "However, we must make an
+investigation."
+
+"How are you going to do it?" asked Mark. "You can't see the end of the
+tube from inside the ship, and, even if we went to the surface it would
+still be under water."
+
+"We are going to look at it while here, under the ocean," said the
+inventor.
+
+"Well, maybe you're a good swimmer," put in Jack, "but I don't believe
+you can stay under, in this depth of water, long enough to see what the
+trouble is."
+
+"I think I can," answered Mr. Henderson.
+
+"How?"
+
+"I'll show you. Washington, bring out the diving suits."
+
+The colored man, his eyes growing bigger every minute, went to a locker
+and brought out what seemed quite a complicated bit of apparatus.
+
+"With the aid of these," said the professor, "I will be able to go out,
+walk along the ocean bed, and investigate the mystery. Do you boys want
+to come along?"
+
+"Is it safe?" asked Mark, who was inclined to be cautious.
+
+"As safe as any part of this under-sea voyage," replied the professor.
+"These diving suits are something I have not told you about," he went
+on. "They are my own invention. Besides the regular rubber suits there
+is an interlining of steel,--something like the ancient suits of chain
+mail--to withstand the great pressure of water. Then, instead of being
+dependent on a supply of air, pumped into the helmet from an apparatus
+in a boat on the surface, each person carries his own air supply with
+him."
+
+"How is that?" asked Jack, and Mark also asked the question.
+
+"Simply by attaching a little tank of the compressed gas to the shoulder
+piece of the suit," said the inventor. "There is enough air in the tank
+to last for nearly a day. It is admitted to the helmet as needed by
+means of automatic valves. In other respects the diving suit is the same
+as the ordinary kind, except that there is a small searchlight, fed by a
+storage battery, on top of the helmet."
+
+In spite of their fears at venturing out under the great ocean, the two
+boys were anxious to try the suits. So, after some hesitation, they
+donned them.
+
+"Here, take these with you," said the professor, before their helmets
+were screwed on. He held out what looked like long sticks.
+
+"What are they?" asked Jack.
+
+"Electric guns," replied the professor. "But come on now, we have no
+time to lose."
+
+Further conversation was impossible, for the boys had their heavy copper
+helmets on, and they were as tightly enclosed as if inside a box. They
+grasped their weapons and waited for the next move.
+
+The professor led the way to the stern of the ship. The boys found it
+hard to walk, as they were weighted down by the heavy suits, and also
+the boots, the soles of which were of lead.
+
+They followed the inventor into what seemed a small room. Inside they
+found themselves in darkness. There was a clanking sound as Washington
+fastened and clamped the door shut. Then came a hissing.
+
+The boys felt water rising about them. They could experience its
+coldness, even through the diving suits. They were much afraid, but the
+professor put a reassuring hand on their shoulders.
+
+They seemed to feel a great weight. It gradually lessened, however, and,
+in a few minutes, they saw something move in front of them. The
+professor pushed them gently forward.
+
+In another instant they were walking on the bed of the ocean, having
+stepped from the _Porpoise_. They had gone into a locked compartment,
+the inner door of which had been tightly closed, after which water from
+outside had been gradually admitted until the pressure was equal, and
+then the boys and the professor had merely to emerge out into the bottom
+of the sea when the outer portal was swung aside by Washington, who
+worked the lever from inside.
+
+The boys were in intense darkness, but, suddenly a light glowed about
+them, and they saw that the professor had switched on his miniature
+search lamp. They remembered how he had told them to work the apparatus,
+and soon tiny gleams shot out from their helmets.
+
+The professor pointed ahead, for not a sound could be heard, and the
+boys followed him.
+
+It was a new sensation, this walking along the bed of the ocean. At
+first the great pressure of water, even though the steel lined diving
+suits kept most of it off, was unpleasant. Gradually, however, the boys
+became used to it. They had to move slowly, for the water was denser
+than the air and impeded their progress.
+
+In a few minutes they reached the forward end of the _Porpoise_. Now
+they were to solve the mystery of what had stopped the submarine. For a
+few moments they could distinguish nothing.
+
+Suddenly the boys felt the professor grasping their arms. They looked in
+the direction he pointed. There in the diffused glare from the search
+light and the illumination of their helmet lamps they saw, wrapped about
+the forward shaft opening a gigantic squid or devil fish. Its soft,
+jelly-like body completely covered the opening of the shaft preventing
+any water from entering, and thus stopping any forward motion to the
+ship.
+
+This was what had caused all the trouble. The _Porpoise_ had run into
+the monster, who feeling what it must have thought an enemy, had grasped
+the submarine with its long sinuous arms.
+
+The professor hesitated a moment. Then he slowly raised his electrical
+gun, and took aim at the hideous mass. The boys followed his example. At
+Mr. Henderson's signal they all fired together.
+
+From the muzzles of the guns darted small barbs that carried with them a
+strong shock of electricity, from storage batteries in the shoulder
+pieces of the weapons. Three of them were enough to produce death in an
+animal as large as a whale.
+
+The devil fish quivered. Then the water about it suddenly grew black,
+and the boys and the professor were in dense darkness, for the squid had
+dyed the ocean with a dark liquid from the sack it carried for the
+purpose.
+
+The explorers groped their way to the left, having fortunately grasped
+hands after firing their guns, to prevent being separated in case the
+terrible fish began a death struggle.
+
+Luckily Professor Henderson went in the right direction and managed to
+locate the _Porpoise_. Then, feeling along her steel sides, he led the
+boys through the inky blackness to the water chamber by which entrance
+could be had to the interior.
+
+In a few minutes all three were safely inside and had removed their
+diving suits. The others crowded about, anxious to learn what had
+happened. The inventor related it briefly.
+
+Once more the engines were started. This time there was no hanging back
+on the part of the _Porpoise_. The big screw revolved, the water came in
+the shaft and was thrust out of the rear end, making a current that sent
+the craft ahead swiftly. The gigantic fish had been killed, and its body
+no longer obstructed progress.
+
+"Now we'll rise to the surface and see how it feels to sail along that
+way for a while," said the professor as he started the pumps that
+emptied the tanks. In a little while the ship was floating on the
+waves.
+
+It was now night, and the clouds overhead made it so dark that it was
+hard to see ten feet in advance. The professor did not want to use the
+searchlight for he did not care to have his presence discovered by
+curious persons. So he ran the ship at half speed.
+
+"Where are we now?" asked Mark, who had entered the conning tower, where
+the professor was steering.
+
+"Somewhere's off the coast of South Carolina," replied the inventor.
+
+The next instant there was a sudden shock and jar. The ship quivered
+from stem to stern, and came to an abrupt stop.
+
+"We've hit something!" exclaimed the professor, shutting down the
+engines with a jerk of the lever.
+
+
+
+
+CHAPTER IX
+
+A PRICE ON THEIR HEADS
+
+
+On board the _Porpoise_ there was great excitement. Washington, with
+Andy, Tom, Bill and Jack came running from the engine room.
+
+"What is it?" cried Jack.
+
+"I don't know," answered the professor as calmly as he could. "We'll
+soon see, however."
+
+He switched on the searchlight and peered from the conning tower.
+
+"Can you see anything?" asked Andy, anxiously.
+
+"I can," announced the inventor.
+
+"What?"
+
+"Land," replied Mr. Henderson. "We've hit the coast."
+
+"I hope we ain't done no damage," put in Washington.
+
+"Do you mean to the coast or to us?" asked the professor, with a smile.
+"I guess there isn't much danger in ramming the shore excepting to the
+_Porpoise_. However, we do not seem to be in any immediate trouble."
+
+He tested various wheels and levers, and announced that, aside from the
+jar, which might have started some of the machinery, the _Porpoise_ was
+unharmed.
+
+The cover of the man-hole was loosened and, one after another, the
+adventurers crawled out on the small deck or platform. It took them a
+little while to become accustomed to the darkness, but soon they were
+able to make out that they had run on the muddy bank of the ocean beach.
+The tide was low and the _Porpoise_ had rammed her nose well into the
+soft muck, which accounted for the lack of damage.
+
+"Well, I guess there is nothing to do excepting to wait for morning,"
+said Mr. Henderson. "It doesn't look like a very lively neighborhood
+about here. I don't believe we'll be disturbed."
+
+Save for the splash and lapping of the waves and the sound of the wind,
+it was as quiet as the proverbial graveyard. Not a light showed on
+shore, and the gleam from the search lamp of the _Porpoise_ cut the
+darkness like a small moonbeam.
+
+"If there's nothing to do I'm going to turn in," said Andy. "I'm tired."
+
+The professor said this was a good suggestion, and, leaving instructions
+that Washington and Bill were to divide the night's watch between them,
+the inventor sought his bunk.
+
+The boys remained on deck a few minutes longer.
+
+"We certainly are getting our share of adventures," remarked Jack.
+
+"I should say so," answered Mark.
+
+"Gollyation yes!" exclaimed Washington. "You-uns done most been eat by
+dat air koslostrous specimen ob a parralleledon! I'm glad I didn't go.
+But I'se brave enough!"
+
+"What's that?" asked Mark suddenly, pointing to an object floating on
+the water.
+
+Washington turned to behold something white drifting along.
+
+"Oh my good land ob mercy! It's a ghost!" the colored man yelled. "It's
+a ghost! Land a' massy! Hide me some where, quick!"
+
+Washington fell on his knees and stretched up his clasped hands in
+supplication. The boys gazed curiously at the white object that was
+slowly floating toward the stranded ship.
+
+It rose and fell on the waves, with an odd motion.
+
+"I wonder what it is," said Mark.
+
+"We'll soon see," spoke Jack. "It's coming this way."
+
+"Don't go near it! Don't touch it, boys!" pleaded Washington. "It'll put
+de evil eye on yo', suah! Turn yo' haids away!"
+
+But the boys were not so easily frightened. The white thing did look
+queer, but Jack reasoned correctly that the darkness of the night
+magnified it, and made it appear stranger than it probably was.
+
+"I'm going to try to get it," said Mark.
+
+The white thing was now quite close. It resembled a bundle of rags,
+floating on top of the water, and, as it came nearer, it seemed to take
+on a curious form.
+
+"It's a baby! It's de ghost ob a little dead baby!" cried the colored
+man. "Let it alone, I tell you!"
+
+Indeed, now that Washington had suggested it, the boys could see a
+resemblance to a child in the white object. But this did not deter them.
+Jack secured a boat hook from where it was fastened to the platform.
+With it he gently poked at the white thing. The object seemed to
+collapse and Jack was conscious of a strange feeling. Then, with slow
+motions, he drew it close to the side of the ship.
+
+Lying on his face he was able to get a good look at the thing. He
+muttered an exclamation.
+
+"What is it?" cried Mark.
+
+"Nothing but a newspaper!" announced Jack with a laugh, as he threw it
+on the deck. "All our trouble for nothing."
+
+"I shore thought it were a ghost," cried Washington as he got up from
+his knees.
+
+The boys went to their bunks. They were the first ones awake the next
+morning, and Jack followed Mark on deck.
+
+"There's the paper you rescued from drowning," said Mark.
+
+"So it is," came from Jack. "I wonder if there's any news in it."
+
+The sheet had dried out and Jack spread it open. No sooner had he
+scanned the first page than he uttered a whistle.
+
+"Something startling?" asked Mark.
+
+"Startling! I guess yes! Look here!"
+
+Mark looked over Jack's shoulder. Staring at them, from amid a mass of
+other news was the announcement in big black type:
+
+ REWARD FOR BOY ANARCHISTS!
+
+Then followed an account of the burning of the hotel at Easton, a vivid
+description with pictures, of how it had been blown up in an attempt to
+assassinate Lord Peckham, and how the two boys, sons of an English
+anarchist, had escaped.
+
+The rest of the story was given over to a description which Jack and
+Mark could see was meant for them though it was incorrect in several
+particulars. How the boys had escaped the detective, through the trolley
+car mishap, was related, and then came the startling announcement that
+the hotel authorities had offered a reward of $1,000 for the capture of
+either or both of the boy anarchists. To this Lord Peckham had added an
+equal sum.
+
+"Well, it looks as if we were of some importance in the world," remarked
+Jack.
+
+"Rather," agreed Mark. "Think of having a price on our heads! Well, that
+detective certainly is a hustler. When is that paper dated?"
+
+Jack looked and saw that the sheet had been issued in Charleston the day
+previous. It had probably been thrown overboard from some steamer, and
+had drifted toward shore.
+
+While the boys were speculating over the matter Professor Henderson came
+on deck. He saw something was up, and soon had the whole story from the
+boys.
+
+"I shouldn't worry about it," said the inventor. "They've got to catch
+you first, and it isn't like running away when you know you are guilty.
+You boys had no more to do with the fire than the man in the moon. And
+we'll soon be beyond the reach of rewards and newspapers."
+
+Nevertheless, the boys brooded over the matter. It seemed that they
+were still under a cloud, and they wished very much that it could be
+cleared away.
+
+However there were soon busy times. The rising tide floated the boat,
+and soon it was riding safely at anchor. The professor needed some small
+bits of machinery, and had decided to send the boys to the nearest town
+for them. But the news in the paper changed his plans, and he sent Bill
+and Washington, who soon returned with the needed articles.
+
+"Now we'll make another start," said Mr. Henderson, as soon as all were
+on board once more. "This time I hope we will keep on until we reach the
+south pole!"
+
+He started the engine, the _Porpoise_ sank beneath the waves, and with a
+hum of the big screw that throbbed and vibrated, was away again.
+
+
+
+
+CHAPTER X
+
+ATTACKED BY A MONSTER
+
+
+For several days the _Porpoise_ plowed her way beneath the surface of
+the ocean. Obedient to the directing hand of Professor Henderson she
+rose or sank as the tanks were emptied or filled. He put the craft
+through several rather difficult movements to test her under all
+conditions. In each one she was a success.
+
+Dinner was sometimes eaten five hundred feet below the surface. Then
+while Washington washed the dishes and cleaned up the galley, Jack and
+Mark looked from the side windows at the strange life under water.
+
+They were getting farther south now and the water was warmer as the
+equator was approached. This produced a great variety of animal life,
+and the ocean fairly swarmed with fishes, big and little, strange and
+curious that could be seen from the glass bull's-eyes.
+
+Great sharks swam up alongside of the _Porpoise_, keeping pace with her
+in spite of her speed. Their cruel tigerish eyes and ugly mouths made
+the boys shudder as they looked at the creatures. Then came odd
+creatures that seemed neither of the land or sea, but which swam along
+with their horrible bodies flapping up against the glass. One and all,
+the inhabitants of the ocean seemed to resent the intrusion of the
+submarine.
+
+One day the boys turned the light out in the cabin and sat in the
+darkness the better to observe the fishes. The sea, in the vicinity of
+the ship, was illuminated with a sort of glow that diffused from the
+searchlight.
+
+Suddenly, as the boys were watching, there came a thud on the glass
+window at the port side. They glanced in that direction to see some
+horrible thing peering in at them through the window.
+
+At first they were greatly frightened. Two big eyes of green, with rims
+of what looked like red fire, stared at them, and, there was an ugly
+mouth lined with three rows of teeth.
+
+"It's only a fish," said Mark.
+
+"Well, I wouldn't like to meet it outside," said Jack. "I'd rather be
+here. My, but it's a nasty sight!"
+
+"Let's give Washington a little scare," suggested Mark.
+
+"How?"
+
+"We'll go out and tell him some one in the cabin wants to see him. The
+fish will stay there. See, it is fastened to the glass by some sort of
+suction arrangement, like the octupus fish have on their arms. Then
+we'll look in and see what Wash does."
+
+Jack agreed to the plan. The boys left the cabin, and Mark called to the
+colored man, who was in the engine room.
+
+"I'll go right instanter this minute," said Washington. "Don't no grass
+grow under dis chile's feet!"
+
+"Now listen," said Mark as he and Jack tiptoed after the colored man.
+
+Washington had no sooner entered the darkened cabin, and caught sight of
+the horrible staring red and green eyes looking straight at him, than he
+let out a yell that could be heard all over the ship. Then the colored
+man dropped on his knees and began to implore:
+
+"Good please Mr. Satan fish, doan take Washington White," he begged.
+"It's all a mistake. I didn't do nuffin. Good please Mr. Satan fish,
+take some one else. It's disproportionate to de circumulation ob de
+interiorness ob dis subicecream ship, so kindly pass me by dis time!"
+
+"What's the matter?" asked Amos Henderson, as he came hurrying into the
+cabin, seeking the cause for Washington's loud cry.
+
+Jack and Mark, who came in at that juncture, were a little bit ashamed
+of the trick they had played.
+
+"What is the trouble?" repeated Mr. Henderson.
+
+"We's all goin' to be devoured alibe!" cried Washington pointing to the
+fish, that still clung to the glass.
+
+"Ah, a sucker fish!" remarked the inventor. "A large specimen, too.
+Don't be afraid Washington, it can't hurt you."
+
+"He looks like he could," said the colored man. "Look at dem teef!"
+
+Indeed the creature's mouth was a horrible sight, as it opened and shut.
+
+"I'll show you how to get rid of him," said the professor.
+
+He turned on the electric lights in the cabin, flooding the room with a
+bright glow. The big fish darted off, and, when the lights were turned
+out again, the terrible eyes did not reappear, much to their
+satisfaction.
+
+"The lights scared it away," remarked the inventor. "But you mustn't get
+frightened so easily, Washington. You'll see stranger sights than that
+before you're through with this voyage."
+
+"Oh I wasn't 'fraid," spoke up Washington. "I were jest 'stonished,
+dat's all."
+
+"What did you get down on your knees for?" asked Mark with a grin.
+
+"I might hab been lookin' for my collar button, for all you knows,"
+replied Washington, with an air of great dignity, and went back to the
+engine room.
+
+For several days after this the _Porpoise_ continued on her way south.
+Now and then appearing on the surface to renew the supply of fresh air,
+and again skimming along under the surface, or deep down, the strange
+craft kept on. It grew much warmer, and even when some distance below
+the surface the heat could be felt in an uncomfortable manner.
+
+"We're getting near the equator," explained the professor.
+
+One afternoon, when dinner had just been finished, and the ship, under
+the direction of Washington, was gliding along well under the sea, there
+came a sudden shock.
+
+"We've hit something!" exclaimed Mr. Henderson as he jumped for the
+conning tower. The shock was repeated.
+
+"What was it?" asked someone.
+
+"Shut down the engine!" yelled the inventor to the colored man. "What do
+you want to go on ramming an object after you've once hit it? Slow down
+the engine!"
+
+"Power's shut off!" cried Washington. "We didn't hit nothin'! Something
+hit us!"
+
+"What do you mean?" asked Mr. Henderson.
+
+"Somethin's rammin' us," went on Washington.
+
+"It must be a big monster. I was sterrin' along an' there was nothin' in
+de road, when all of a suddint, ker-plunk! We's hit. Look ahead, an' you
+can't see nothin'!"
+
+The professor, and the boys, who had followed him, gazed out of the
+conning tower window. There was nothing forward but a vast expanse of
+water.
+
+The next instant the ship careened as something struck her a violent
+blow on the port side. Everyone almost toppled over from the force of
+the impact.
+
+"Dar he goes agin!" cried Washington.
+
+"We're attacked by a whale!" said the professor. "We must rise to the
+surface or it may damage the ship."
+
+"If it's a whale I'd like to get a shot at it," put in Andy Sudds, from
+the foot of the companion ladder leading into the tower.
+
+"I don't know that it is a whale," went on the inventor. "But it must be
+something very big and strong."
+
+"It's a monster of some sort," put in Andy, "and I want a chance at
+him."
+
+"It's too risky," murmured the professor. "We couldn't get down to
+bottom here, as the water is several miles deep, and the pressure would
+crush the _Porpoise_, strong as she is."
+
+Once more came a terrible blow and the ship rocked in a swirl of foam
+beneath the waves. In quick succession two more fierce onslaughts were
+made by the unseen monster.
+
+"We'll have to do something," muttered Andy.
+
+"You're right," agreed the professor. "Our only chance is to rise to the
+surface, for I do not believe the creature will follow us there. Empty
+the tanks, Washington."
+
+The colored man started the pumps, and the professor watched the gages
+that told the depth of the craft. The pointer should have begun to swing
+around in a few seconds after the tanks began to empty. Instead it
+remained stationary.
+
+"Strange," said Mr. Henderson. "I wonder if anything is wrong with the
+machinery."
+
+"More like the whale, or whatever it is, is on top of the boat, holding
+her down," suggested Andy.
+
+There was no doubt of this a moment later, for there were several
+violent blows on the upper part of the _Porpoise_.
+
+The crew of the submarine were held prisoners below the surface by the
+unknown monster!
+
+For a few minutes the thought of the awful fate that would be theirs if
+the ship should be wrecked under the water made each one speechless. As
+they stood looking at each other, not knowing what to do, the attack was
+renewed on the port side.
+
+The big fish, whale or whatever it was, kept pounding away.
+
+"I have an idea!" cried Andy suddenly.
+
+"What is it?" asked the professor quickly.
+
+"Let me put a diving dress on," began the old hunter.
+
+"I tell you we can't sink to the bottom in this depth of water,"
+interrupted the professor.
+
+"We don't need to," put in Andy. "All I want is a diving suit and a
+chance to stand out in the diving chamber. I guess I can fix Mr. Whale,
+if I have one of those electric guns."
+
+"Quick! Get a diving suit, Washington!" cried Mr. Henderson. He saw what
+the old hunter planned to do.
+
+In a few minutes Andy was dressed in the suit. The attacks of the
+monster had redoubled in frequency, and the ship rocked as in a storm.
+
+Andy stepped into the diving chamber, clasping the electric gun. The
+inner door was tightly closed and then the sea cocks that admitted water
+from the outside were opened. When the pressure inside the chamber was
+equal to that of the ocean outside some one pulled the lever that
+opened the outer door.
+
+Andy knew better than to step outside. He remained in the chamber, like
+a sentinel hid in the embrasure of a wall, for the chamber was a sort of
+big dent in the side of the _Porpoise_.
+
+Once more the ship rocked from a terrific blow, and the old hunter was
+nearly thrown out and into the fathomless depths below.
+
+He clung to the door lever and peered out. Through the big glass eyes of
+his copper helmet he saw headed straight at him a whale that seemed
+larger than the submarine.
+
+
+
+
+CHAPTER XI
+
+CAUGHT IN A SEA OF GRASS
+
+
+"It's all up with me and the ship, too," thought Andy as he stood in the
+small chamber and watched the oncoming of the monster.
+
+However, he was not going to die without a fight, so he raised the
+electric gun. Yet he knew it was a most forlorn chance.
+
+He aimed straight down the big open mouth and pulled the trigger. The
+next instant the water all about him was a mass of foam, through which
+he could dimly see that the whale had halted.
+
+And, as the old hunter watched, in awe and fear at what he saw, he noted
+that instead of one monster there seemed to be a pair. Together they
+were threshing the sea into a bloody foam.
+
+Then, turning on the searchlight in his helmet, Andy beheld a terrible
+sight. The whale had been attacked by a gigantic swordfish at the moment
+the hunter had fired the shot, and it was that, and not the electric
+bullet, that had stopped the infuriated animal's rush at the ship.
+
+Ancient enemies, the whale and swordfish, had met in mortal combat. The
+swordfish had engaged the whale just as it was about to strike what
+would probably have been a blow that would have disabled the submarine,
+for with the door of the diving chamber open, the onslaught might not
+have been withstood.
+
+Rushing here and there, the whale seeking to destroy his enemy with a
+sweep of the enormous flukes, and the swordfish plunging his bony weapon
+again and again into the whale, the two monsters fought until the water
+about the ship was a mass of foam and blood.
+
+Much as he wanted to see the end of the fight, Andy knew it was
+dangerous to remain longer with the door open.
+
+He closed it, pressed the lever which started the pumps, forcing the
+water from the chamber and, in a few minutes, emerged into the interior
+of the ship.
+
+Mr. Henderson, realizing that something out of the ordinary was going
+on, had opened the slides of the bull's-eye windows, and those in the
+submarine saw part of the fight between the whale and swordfish.
+
+As soon as Andy had removed his diving suit he advised that the ship be
+sent to the surface, as there might be danger should the monsters get
+too close in their struggles.
+
+Accordingly the pumps, which had been stopped when it was found
+impossible to raise the ship, because of the weight of the whale, were
+started and the _Porpoise_ was soon on the surface.
+
+The manhole cover was opened and Andy, with Jack and Mark, went out on
+deck. They had no sooner stepped out on the platform than there was a
+commotion in the water.
+
+"They're going to fight up here!" exclaimed Mark.
+
+A big body shot upward and fell back with a splash, rocking the
+submarine.
+
+"There's the whale," observed Andy. "But I reckon he won't fight any
+more. He's dead."
+
+It was so. The swordfish had conquered, and the lifeless body of the
+whale floated on top of the water, only to sink a little later.
+
+"It was a great battle," said Jack. "I'm glad I was inside the ship."
+
+The course was due south, and every minute it seemed to the boys that it
+was getting warmer, for they were approaching the equator. Every hour
+brought them nearer the south pole, though they were still several
+thousand miles from it.
+
+After a while quite a wind sprang up, and as the sea roughened the
+professor decided to go down under the surface. The _Porpoise_ sunk as
+the tanks filled and, in a little while, the submarine was in calm
+water, and was forging ahead at three-quarter speed.
+
+It was three days after the adventure with the whale when, as the ship
+was going along at a good rate, that there seemed to be a gradual
+slacking in the progress.
+
+"I wonder what Washington is slowing down for," said the professor
+rising from the dinner table at which all save the colored man had been
+sitting. "I told him to keep right on. He must have seen something
+ahead. I'll take a look."
+
+The inventor went to the conning tower, where Washington was steering.
+
+"What are you stopping for?" he asked.
+
+"I'm not slowin' down," replied the colored man. "Guess another ob dem
+debil fishes has grabbed holt ob de ship. Dey suttinly am de most
+koslostrous conglomerations ob inconsequence dat I eber see."
+
+"You must keep your big words for another time," remarked Mr. Henderson,
+who seemed worried. "Hurry to the engine-room and see if the machinery
+is all right. We certainly are slowing down, from some cause or other."
+
+The _Porpoise_ was now scarcely moving, though from the vibration it was
+evident that the engines were working almost at top speed. Washington
+came back and reported that the big screw was revolving properly and
+that all the machinery was working well.
+
+"Then we're caught in something," said the professor. "Shut off the
+power, Washington, I don't want to strain things."
+
+The ship was now scarcely making a foot a minute, and, a little later,
+when the colored man had turned off the engine, the submarine became
+stationary, merely undulating with the roll and heave of the ocean.
+
+Hurrying to the cabin, Captain Henderson opened the side window
+shutters, turned off the electric lights and peered out.
+
+"I can't see anything," he said. "Yet I should be able to, as we are not
+very deep."
+
+The gage showed that the ship was submerged only thirty feet, and at
+that depth there should have been no difficulty in seeing, at least
+dimly, objects under water. But the windows showed as black as night.
+
+"Bring me one of the portable searchlights," called Mr. Henderson.
+
+Washington brought one, operated by a storage battery. Holding it so the
+reflector cast the beams out of the bull's-eye and into the water on the
+opposite side, the inventor peered forth.
+
+"I was afraid of this!" he murmured.
+
+"What is it?" asked Jack.
+
+"We are caught in the Sargasso Sea," replied Mr. Henderson.
+
+"The Sargasso Sea?" repeated Mark, in a questioning tone. "What is
+that?"
+
+"It is a great sea of grass," replied the captain. "An immense ocean of
+sea weed, that sometimes floats on the surface and sometimes a little
+below. The stalks or blades of the grass are very long and closely
+matted together."
+
+"Is there any danger?" asked Andy in some alarm.
+
+"Very much," answered the professor quietly. "A ship, once fairly
+entangled in the grass or sea weed, seldom gets out. If it is a sailing
+ship the weed clings to the rudder, making steerage impossible, and even
+in a strong wind the ship cannot get free of the mass. The grass winds
+about the propellers of steamships, and holds them as tight as in a
+vise.
+
+"Sometimes a great storm may tear the mass of weed loose from the bottom
+of the ocean, and then the ship is free. But the Sargasso Sea is the
+graveyard of many a fine vessel."
+
+The pumps were set going. Anxiously everyone watched the gage. The
+pointer never moved, but remained at thirty feet. The _Porpoise_ was
+caught.
+
+"Well, since we can't go up, let us see if we can go down," said the
+inventor. "Perhaps we can dive under the sea weed."
+
+The cocks of the tanks were opened and the water rushed in. Under the
+weight of it the ship should have sunk to the bottom. Instead it
+remained just where it was, thirty feet below the surface.
+
+"Try the screw again," suggested Andy, "Maybe we can back out."
+
+The big propeller in the tube was started going in a reverse direction,
+but the _Porpoise_ only moved a few feet and then stopped. To go forward
+was equally impossible.
+
+The submarine was held fast in the grip of the long, sinuous, snake-like
+fingers of the terrible sea grass. Weak as one strand was, the thousands
+combined served to fasten the ship as securely as wire cables would have
+done. The weeds had entangled themselves all around the craft and
+refused to let go.
+
+"Well," remarked Mr. Henderson when all efforts had failed. "We must
+think of a new plan."
+
+He spoke cheerfully, for he did not want the boys and other members of
+the crew to know how worried he was. This was a danger he had never
+counted on when he planned to go to the south pole.
+
+"There is no great hurry," Mr. Henderson went on in a few minutes. "We
+can stay here for several days if need be, and by that time a storm may
+tear the grass loose."
+
+"If we had our old hay sythes here," spoke Bill, "me an' Tom could put
+on divin' suits an' go out an' cut the sea weed."
+
+"I'm afraid that wouldn't work," answered Mr. Henderson. "I'll think up
+some plan, soon."
+
+He started toward the engine room to look over the machinery. He was met
+by Washington, who seemed much alarmed.
+
+"What's the matter?" asked the inventor.
+
+"De air tank hab busted an' all de air is escapin' out!" cried the
+colored man. "We'll all smothercate!"
+
+
+
+
+
+CHAPTER XII
+
+FIRE ON BOARD
+
+
+The professor jumped past Washington and hurried into the room where the
+tanks were kept, carrying the reserve supply of air for breathing when
+the ship was under water. A loud hissing told that the leak was a large
+one.
+
+"Quick! Bring me some tools and a steel plug," shouted the captain.
+
+Mark hurried in with the things the professor wanted. But before the
+plug could be put in the hole the air stopped hissing.
+
+"The leak is fixed!" cried Jack.
+
+"No," said the professor in a strange voice.
+
+"But the air no longer rushes out."
+
+"For a good reason, there is no longer any air to rush out. It is all
+gone!"
+
+"Do you mean to say that all the reserve stock has been lost?" exclaimed
+Andy.
+
+"I fear so. The leak must have been a bad one. The air was stored in
+tanks under pressure, and, as you know, we released it as we needed it.
+Now it is all gone."
+
+"All? Then we shall smother," said Jack, and his voice trembled.
+
+"Not at once," went on Mr. Henderson in a calm voice. "There is enough
+air in the entire ship, including that which has leaked from the tanks
+to last us five hours. After that----" he paused and looked at his
+watch.
+
+"Well?" asked Andy. "After that?"
+
+"There is enough stored in the small tanks of the diving suits to last
+another two hours, perhaps. Seven hours in all."
+
+"Then what?" asked Mark.
+
+"We shall smother to death," said the professor in a low tone. "That
+is," he went on, "unless before that time we can raise the _Porpoise_ to
+the surface of the sea and get a fresh supply of air."
+
+"Then we must work to raise the ship," put in Bill. "Let' get out and
+see if we can't cut through the sea weed."
+
+"It would be useless," said Mr. Henderson. "We can only depend on the
+power of the ship herself. But do not be discouraged. We may escape.
+Come, Washington, start the engine again. By keeping it going constantly
+we can, perhaps, break loose from the grass. It is our only hope."
+
+Steadily the machinery worked. It might as well have remained
+stationary, however, as far as any noticeable effect was made on the
+boat's progress. The grass of the Sargasso Sea held the _Porpoise_ in a
+firm grasp.
+
+Four hours passed. There was nothing to do but wait and see what would
+happen. It all depended on the engines. Silently the navigators of the
+realms under the ocean sat and hoped. Now and then the professor would
+go to the engine room to adjust the machines.
+
+The atmosphere in the cabin was growing noticeably heavier. The boys'
+heads began to ring with strange noises, and there was a tightness
+across their chests. The lack of fresh air was beginning to tell.
+
+"We might as well use that in the diving suit reservoirs," remarked the
+professor. "We will feel better, at least for a little while."
+
+The helmets of the suits were brought in, and the vapor released from
+the small tanks. A change was at once noticed. The old stale air in the
+cabin was forced out of the exhaust pipes, and the fresh took its place.
+Every one felt better.
+
+Faster and faster revolved the big screw. The ship vibrated more and
+more. Yet it did not move, nor did it rise. The crew were still
+prisoners beneath the water.
+
+For an hour or so conditions were fairly comfortable. Then the same
+unpleasantness was experienced as was noticed before.
+
+"If we could only open a window," sighed Mark, "and let in a lot of
+fresh air, how nice it would be."
+
+The air rapidly became more foul. Soon Washington was gasping for
+breath. Tom and Bill showed signs of uneasiness.
+
+"Lie down on the floor," counseled the professor. "You will find the air
+a little fresher down there."
+
+They all did as he advised, the inventor himself stretching out at full
+length. A little relief was experienced.
+
+They knew it could not last long. Even the professor seemed to have
+given up hope. The engine was not going to free the ship in time to save
+the lives of those on board.
+
+Washington crawled to the engine room, as some of the bearings needed
+oiling. The professor seemed in despair. He opened one of the slides
+that covered the glass bulls eye windows. Then he turned off the
+electric lights. The opening was black, showing that the sea of grass
+still surrounded them. With a groan Mr. Henderson turned aside. The last
+hope was gone. He sank down on the floor of the darkened cabin.
+
+Just then Mark happened to look at the bull's-eye. He saw a glimmer of
+light. Then he noticed several fishes swimming about. The water was
+clear. The grass had disappeared from the vicinity of the window.
+
+"Look!" cried Mark to the professor.
+
+The inventor peered forth. As he did so he uttered a cry. Then he
+staggered rather than ran to the engine room.
+
+"What are you doing?" he called to Washington.
+
+"I jest let some ob de sulphuric acid out ob de storage battery tank,"
+replied the colored man.
+
+"That's it! That's it!" exclaimed the professor. "Quick, let some more
+out, Washington. Let out all there is in that tank. It will save our
+lives."
+
+Wonderingly Washington obeyed. The air in the ship was growing more foul
+every second. It was hard to breathe even on the floor, and all were
+gasping for breath. A few minutes more and they would all become
+unconscious and death would come in a little while if the air was not
+freshened.
+
+The professor staggered back to the main cabin. He looked out of the
+bull's-eye windows. Then he exclaimed:
+
+"See, it is getting lighter! Thank Heaven we are saved!"
+
+The next instant the ship began to move backward. Then with increasing
+speed it pulled out of the grip of the long grass, and in another minute
+was floating on top of the water, at the edge of the Sargasso Sea.
+
+"Quick! Open the man hole cover!" said Amos Henderson.
+
+Washington threw back the lever cams, and in rushed the fresh air. It
+was a blessed relief from the terrible oppressiveness of the foul
+atmosphere of the boat. They all breathed deeply, and, in a few minutes
+the effects of their long imprisonment had passed off.
+
+They went out on the small deck. It was getting dusk, and the reflection
+of the red sunset shone brightly on the heaving water.
+
+"I 'spected I'd neber see dis again," said Washington. "Thought suah I
+was a gone chicken!"
+
+"We had a most fortunate escape," said the professor. "You did the trick
+for us when you let the acid run from that tank into the sea. It mingled
+with the water and burned or ate through the stems of the grass so they
+no longer held the ship. I saw what had happened as soon as I looked out
+of the bull's-eye, and that's why I had you turn out all the acid you
+could. It was just as if liquid fire had touched the sea weed and burnt
+it off."
+
+"Golly!" exclaimed Washington. "Fust I know I'll be a perfessor myself!"
+
+Supper was eaten with the ship on the surface of the ocean, for it was
+impossible to go below until the leak in the air tanks had been
+repaired. Work was begun on this the next day, and though it proved a
+difficult job it was accomplished by Mr. Henderson and the boys.
+
+There were several minor repairs to be made to the machinery, and it was
+a week before all was in readiness for another descent beneath the
+waves. In the meanwhile the craft had moved slowly southward on the
+surface, where no very great speed was possible.
+
+Toward evening, on the seventh day after their adventure with the
+Sargasso Sea, the travelers closed the man hole, and with air tanks well
+filled slowly sank beneath the waves. Supper was eaten at a depth of
+sixty feet, and after the meal, while Washington was washing the dishes,
+the others sat and looked out through the bull's-eyes at the big fishes
+which floated past.
+
+"I wouldn't like to catch one of them air things on my hook an' line,"
+observed Bill, as a particularly large fish went past. "I reckon I'd
+have trouble landin' him."
+
+"More likely he'd pull you in," said Mark.
+
+For several minutes they watched the strange procession of deep-sea
+life. Presently Jack, who was sitting near the engine room door, sprang
+up. At the same instant there was the sound of an explosion.
+
+"What's the matter?" cried the professor.
+
+"Come quick!" yelled Washington.
+
+"It's a fire!" yelled Jack. "One of the electrical fuses has blown out,
+and the ship is on fire!"
+
+
+
+
+CHAPTER XIII
+
+THE GHOST OF THE SUBMARINE
+
+
+They all rushed toward the engine room. It was dark, because the lights
+had gone out all over the ship, and they could see only by the glare of
+the flames, which were increasing.
+
+"Light one of the oil lanterns!" called the professor, and Bill did so.
+
+"Unreel the hose," the inventor continued, and Mark and Jack ran to do
+this.
+
+In a few minutes the line was stretched into the engine room, and water
+was being thrown on the flames, for Washington had started the pump as
+soon as he saw the conflagration.
+
+The fire was in one corner, near the electrical switch board, and had
+been caused by the blowing out of one of the fuses, which occasioned the
+little explosion. The wood work near the switches was blazing fiercely,
+and soon the ship was filled with smoke.
+
+"Empty the ballast tanks!" called the professor. "We must rise to the
+surface!"
+
+"We'll all be burned up!" cried Tom. "First we nearly smother and then
+we get on fire. Neber saw such luck!"
+
+With a rush the _Porpoise_ began to rise, as her tanks were lightened.
+With steady hands, though with fear in their hearts, Jack and Mark
+continued to play the water on the flames, while the professor and
+Washington got out a second line and aided them.
+
+"The fire is dying out!" exclaimed Mr. Henderson. "We'll soon get the
+best of it."
+
+In five minutes the worst was over, though it had been an anxious time,
+and one of danger. The ship came to the surface, and the open man-hole
+let out the thick smoke that had nearly suffocated the travelers.
+
+As soon as it was cool enough in the engine room an examination was made
+of the damage done. It was not as bad as the professor had feared, and
+the running part of the ship was not harmed. A new fuse was put in and
+the electric lights turned on.
+
+The night was spent with the ship floating on the surface of the ocean,
+only enough speed being kept up to give her steerage way. The professor
+did not want to go below the waves until he had repaired the switch
+board.
+
+Watch was kept, for, though they were out of the regular line of ocean
+travel, there was no telling when a vessel might come along and run
+them down, for the _Porpoise_ did not show above the waves more than a
+few feet, and carried no lights.
+
+Mark had the watch just after midnight, and was sitting in the conning
+tower, the door of which opened out on the small deck. He had swept the
+surface of the water with powerful glasses and was sure there were no
+ships in sight. So, feeling that he would like to stretch his legs, he
+walked up and down on the platform.
+
+He had reached the after end, and was about to turn and go back, when he
+was startled to see between him and the conning tower a white object. At
+first Mark thought it was a cloud of mist, or something the matter with
+his eyes. He rubbed them, but the object did not disappear.
+
+Then it moved, and, to his horror Mark saw that it had the shape of a
+man, tall and thin. The two arms were outstretched, and to Mark's
+imagination seemed to be pointed toward him.
+
+In spite of trying not to be, Mark was frightened.
+
+He did not believe in ghosts, and had always felt that all stories about
+them were due to persons' imaginations. Now he saw something that was
+hard to explain.
+
+As he watched it, the white object turned and glided without making the
+slightest noise, toward the conning tower. It entered and Mark breathed
+a sigh of relief.
+
+Perhaps, after all, it was some one from down in the cabin, maybe the
+professor himself in his night shirt, who had come up to see that all
+was right.
+
+"I'll go and look," said Mark to himself.
+
+He had to nerve himself for the ordeal, as, in spite of assuring himself
+that there were no such things as ghosts, he was frightened.
+
+It was absolutely quiet. The only sound was the gentle swish of the
+water against the sides of the ship. The engine was running so slowly
+that it caused no noise.
+
+Half way on his journey to the conning tower Mark paused. There,
+advancing toward him, was the white object. With outstretched arms it
+glided nearer and nearer until Mark's heart was beating as if it would
+burst through his ribs. His mouth was dry and he could not have cried
+out had he tried.
+
+There was a splash in the water off to the left as some big fish sprang
+out and dropped back again. Involuntarily Mark turned in that direction.
+Then he thought of the ghost and looked for it again. To his surprise
+the white object was nowhere to be seen!
+
+The boy waited a few minutes, and then, screwing up his courage, he went
+to the tower. There was no one inside, and, along the length of deck
+nothing was to be seen of the ghost.
+
+"I wonder if I have been asleep and dreaming," the boy asked himself. He
+gave his leg a pinch, and the sensation of pain told him he was not
+slumbering.
+
+"Well, I'll say nothing about it," Mark went on to himself. "They'll
+only laugh at me."
+
+Entering the tower Mark looked for the glasses in order to make another
+observation. He could not find them, yet he was sure he had left them on
+a shelf in the tower.
+
+"I wonder if the ghost took them," he said.
+
+He heard some one coming up the iron stairs of the small companionway
+that led down into the interior of the ship through the man-hole. At
+first he thought it was his queer midnight visitor returning. Then the
+head and shoulders of Jack appeared.
+
+"I've come to relieve you," said Jack. "Your watch is up; it's two
+o'clock. Here are the night glasses. I found them on the cabin table. I
+thought you had them with you."
+
+"I did," replied Mark.
+
+"Then how did they get below?"
+
+"I--I don't know," said Mark.
+
+The mystery was deepening, yet he did not want to tell Jack just yet.
+
+"Well, that's queer," remarked Jack. "Maybe the captain came up and got
+them while you were asleep."
+
+"I didn't go to sleep," answered Mark rather crossly.
+
+Jack said nothing more, but took his place in the conning tower, while
+Mark went below. Thinking to discover if the ghost might by any chance
+have been one of the persons on the _Porpoise_, Mark looked into each
+bunk. From the captain to Washington, all the inmates were peacefully
+slumbering.
+
+"Queer," murmured Jack, as he took a look into the engine room before
+turning in. The engine needed no attention, as it worked automatically,
+and all there was to do was to steer the ship. Even this needed little
+care as the course was a straight one, and the wheel could be locked,
+leaving the lookout little to do.
+
+"Did you see anything during your watch?" asked Mark of Jack the next
+morning.
+
+"See anything? What do you mean?"
+
+"I mean anything unusual."
+
+"Nothing, only a school of porpoises went past and gave me a little
+scare. They were like a lot of water kittens at play."
+
+Mark concluded he would say nothing of the white visitor until he
+ascertained whether any one else had seen it.
+
+It was several nights later, when the ship was once more proceeding
+slowly along the surface of the water, that the ghost again appeared.
+This time Washington had the midnight watch.
+
+But the colored man was not one to remain quiet when he had such a scary
+visitor, and his yells aroused the ship.
+
+"It's a ghostess! A big white ghostess!" yelled Washington. "I don seen
+it wid my eyes, an' it waved his arms at me. I's goin' to die suah!"
+
+"What's all this nonsense?" demanded the professor sternly. Then
+Washington, more or less excitedly, told of what he had seen. It was
+just as it had happened to Mark.
+
+"You were dreaming," said the professor to Washington. "There are no
+such things as ghosts."
+
+Every one, from old Andy to Tom and Bill, had been roused by
+Washington's cries, and listened to his story. At the close of the
+recital of how the white thing had suddenly disappeared, Washington
+refused to continue his watch, unless some one stayed with him.
+
+Mark volunteered to do this. He was anxious to see if the ghost would
+reappear to him. But nothing happened; and the rest of the night passed
+off quietly.
+
+The next day the _Porpoise_ was taken below the surface, in order to
+allow of better speed being made. She was running along, submerged to a
+depth of two hundred feet, when there came a sudden jar, and the ship
+stopped.
+
+"More trouble!" exclaimed the professor.
+
+He opened the slide covering the bull's-eye windows and looked out. All
+about was swirling muddy water.
+
+"Can you see anything?" the inventor called to Jack, who was in the
+conning tower.
+
+"We've run into a mud-bank, and are stuck fast," called back the boy.
+
+
+
+
+CHAPTER XIV
+
+DIGGING OUT THE SHIP
+
+
+"Reverse the engine!" called the professor. "Maybe we can back the ship
+out."
+
+Washington set the big screw to revolving in the opposite direction. The
+_Porpoise_ shook and shivered but the mud held her fast.
+
+"We must have gone in pretty deep," commented Amos Henderson. "Luckily
+it was soft mud instead of a rocky reef or we'd have damaged the ship
+beyond repair."
+
+For several minutes the engines were kept on the reverse, but all to no
+purpose. The sticky mud was like glue in its holding power and the ship
+had buried her prow deep into it.
+
+"I guess we'll have to dig our way out," said the professor, after
+taking a careful view of the big mud bank from the conning tower.
+"Washington, get out the diving suits and the spades."
+
+"Are we really going out in the water to dig?" asked Tom.
+
+"Of course," said Mr. Henderson. "You'll be as safe as in the ship,
+wearing one of my diving suits. We'll all have to help, for it will be
+quite a task."
+
+The queer suits were brought out, and the reservoirs in the helmets were
+filled with compressed air. It was decided to have Washington remain
+within the _Porpoise_, to watch the machinery and start the engine when
+the digging was partly done, in order to see if the ship would not pull
+herself free when some of the mud had been removed from the prow.
+
+"And we may need Washington for another purpose," said the professor.
+
+"What for?" asked Mark.
+
+"Well, he'll have to stay by the diving tank, to let us in quickly in
+case of emergency."
+
+"Do you think there'll be an emergency?" asked Jack.
+
+"You never can tell," was the answer. "We are in deep water, and I don't
+want any accidents to happen."
+
+In a few minutes all save Washington were in their diving suits and
+ready to go out and walk on the bottom of the sea. They entered the
+tank, the door was closed, and then water was slowly admitted from the
+ocean. When the tank was full, led by the professor, they stepped out on
+the muddy floor of the ocean.
+
+At first the pressure of the water at so great a depth bothered them.
+But, as we know, the diving suits were reinforced with plates of steel,
+and so strong that little more than an extra weight of water was
+noticed. They soon became used to it. Each one carried a spade, while
+the professor, Andy and the boys each had, slung about their necks by
+straps, one of the electric guns.
+
+Cautiously they walked toward the big mud bank. They had to go slowly
+because of the weight of the water above them, and because they might at
+any minute step into some muck hole and sink down. Fortunately, however,
+they found there was a firm bottom right up to where the bank of mud
+reared upward.
+
+Turning on the electric lights in their helmets, the voyagers were able
+to see quite distinctly. The _Porpoise_ had rammed her nose into the
+under-water hill for a distance of about ten feet. It was going to be no
+easy matter to get her free, but the divers lost no time.
+
+Vigorously they attacked the big hill of mud. They dug their spades in
+and tossed the earth to one side. It was a strange place to work. At
+first the weight of water hampered every one, but they soon became used
+to it and were able to proceed more rapidly.
+
+From the conning tower Washington kept watch of their progress. When
+they had gone in about five feet he started the engines, hoping the
+_Porpoise_ might now pull herself free. But the mud still held.
+
+By signs, for it was of course impossible for any one to hear or speak,
+attired as they were in helmets and suits, the professor motioned that
+they must dig deeper.
+
+Once more they attacked the big mud bank with their shovels. Farther and
+farther they went into the muck until it seemed that the nose of the
+submarine must be free. But when Washington started the engines it was
+obvious that the ship was still held.
+
+Again the digging was resumed. All at once, while every one was wielding
+his spade to best advantage, a shadow seemed to cover the water. It
+loomed up large and black, and the professor stopped and gazed upward.
+What he saw made him drop his spade and grab the gun that was about his
+neck.
+
+Floating in the water above the diggers, were three immense sharks.
+Their cruel mouths were partly open, showing three rows of big teeth,
+and they were slowly turning over on their backs to make a sudden rush
+and devour the men and boys. Owing to the peculiar shape of its maw a
+shark can not bite until it turns over.
+
+The professor motioned for Bill and Tom to move behind him, and
+signalled for Jack, Mark and Andy to stand close with their weapons
+ready.
+
+The sharks floated lazily downward as if they knew they had the diggers
+at their mercy. To run and escape was impossible, for no one could run
+hampered by the weight of water and his diving suit.
+
+One of the terrible fish opened its mouth wider and, with a flirt of its
+tail aimed straight for the professor. Mr. Henderson raised his gun, and
+took careful aim at the middle of the fish, half turned over. Unerringly
+the electric bullet sped on its way. It entered the soft under part of
+the shark, and immediately the thing struggled in its death agony.
+
+The water was dyed with blood. At the same instant the other sharks
+rushed forward in a swirl of foam. The boys and Andy fired as best they
+could, and must have hit one of the creatures for there was a greater
+commotion.
+
+But the fight was not over. Instantly the ocean seemed alive with the
+giant fish. Attracted by the blood of the killed ones, scores of the
+tigers of the seas rushed toward the scene of combat making matters
+livelier than ever.
+
+The professor, the boys and Andy fired their guns at random. Redder and
+more red became the water until their helmet lamps barely glowed in the
+crimson sea. It seemed that a whole army of the voracious sharks had
+attacked them.
+
+The professor realized that to stay and attempt to fight all the sharks
+in that part of the ocean was impossible. He motioned for the boys and
+Andy to follow him. Then he slowly led the way back to the ship.
+
+But the sharks were not to be gotten rid of so easily. Several of the
+largest followed the diggers, their horrible eyes, and big mouths with
+rows of cruel teeth, striking terror to the hearts of all.
+
+One of the creatures made a rush for Bill and Tom who were close
+together. Either or both of the men would have been bitten in twain, in
+spite of the protection of their diving suits, had not Mark, with a snap
+shot, killed the fierce fish.
+
+It was now a running fight, and yet not so much that, because to run was
+impossible. However, they hurried all they could, and, by dint of quick
+firing kept the ugly creatures at bay until the side of the ship, where
+the diving tank was placed, was reached.
+
+The professor stepped to one side, and motioned for the others to
+proceed him in entering. Little time was lost. As Bill, the last one in,
+stepped past the steel door the inventor attempted to enter. To do so he
+had to let go of his gun.
+
+Instantly one of the sharks made a rush for the old man. But Andy was
+on the watch. He leaned forward, and, from his weapon sent a bullet
+straight down the throat of the monster. The electric missile did its
+work well, and the lifeless body of the shark was devoured by the others
+of its tribe.
+
+The professor pulled the door shut behind him. Then he set the pump to
+work to empty the tank. As he did so there was a tremor to the ship.
+What could it mean?
+
+In a few minutes the tank was empty and the divers stepped out into the
+ship, freed from the oppressive weight of water. The ship continued to
+vibrate and seemed to be in motion.
+
+"What is it?" asked Mark as soon as he had his helmet off.
+
+"De ship am free! We've got off de mud bank!" exclaimed Washington,
+running in from the engine room.
+
+It was true. Enough had been dug so that, with the power of the screw
+working backward, there was sufficient force to pull the _Porpoise_ from
+her perilous position.
+
+"Empty the tanks and rise to the surface," said the professor.
+
+In a few minutes the ship was on top of the waves, the adventurers freed
+from the double danger of the mud and sharks. They congratulated each
+other on the good outcome of the fight with the monster fishes.
+
+Wearied with their labors and the battle under the waves, the travelers
+sat up on the deck breathing in the fresh breeze. Then, after a while,
+supper was made ready and eaten with good appetites.
+
+It was decided hereafter to sail along near the surface at night, and
+not to submerge the ship deeply save during daylight, when it was easier
+to distinguish objects under the water.
+
+Following this plan the _Porpoise_ steamed along just awash that night,
+and the next day was sent down about fifty feet below the surface.
+
+One afternoon, when the travelers were resting, having partaken of a
+fine meal, the professor went on deck to make some observations, the
+ship having been raised for that purpose. He came down, somewhat
+excited.
+
+"Well, we're half way to the pole," he announced.
+
+"How can you tell?" asked Mark.
+
+"Because we have just crossed the equator. We went over the imaginary
+line three minutes ago."
+
+"I was wondering what made it so warm," said Jack.
+
+"I guess you dreamed it was hotter," spoke the professor. "It has been
+just as hot as this for the last few days. Crossing the line makes no
+difference."
+
+"Then we are really in the southern hemisphere now," said Mark.
+
+"That's where we are," replied Mr. Henderson.
+
+He put his instruments away.
+
+"Well, we may as well go below the surface again," he remarked.
+
+"Come quick! Hurry up!" yelled Washington from the deck. "Dar's a
+shipwreck up heah! Somebody's on it!"
+
+
+
+
+CHAPTER XV
+
+THE STRANGE SHIPWRECK
+
+
+The professor, followed by the boys and Tom, Bill and Andy hastened on
+deck. They saw Washington pointing excitedly off to the west. There,
+rising and falling on the easy swell, was the wreck of a large vessel.
+
+She had been a three masted schooner, but now only the stumps of the
+masts remained and the craft was rolling to and fro. It had settled low
+in the water, and was quite deep by the head, so that, at times, the
+waves broke over the bow in a shower of spray.
+
+But what attracted the attention of the adventurers more than anything
+else was the sight of two figures near what had been the after cabin of
+the ship.
+
+There they stood, frantically waving their hands toward those on the
+submarine. Across the water that separated the two craft, there came a
+faint hail.
+
+"I suppose they are nearly dead," exclaimed the inventor. "We must save
+them."
+
+He ordered the _Porpoise_ sent ahead slowly toward the wreck. The
+distance was about half a mile, and was soon covered. As the submarine
+approached closer those on the schooner could be observed more plainly.
+
+"One of 'em is a woman!" exclaimed Jack, who was using the glasses.
+
+"Let me see," spoke the professor.
+
+"You're right," he added. "The other is a little girl."
+
+A few minutes later the _Porpoise_ was alongside. The woman and child
+came to the rail of the schooner, which was barely five feet above the
+waves.
+
+"Can you jump down, or shall I come aboard and get you?" asked Mr.
+Henderson seeing the woman hesitate.
+
+"I can jump down, if you will catch the child," said the woman. "Oh I am
+so glad you came," she added. "We are almost dead from hunger and
+thirst, and the wreck is ready to sink and cannot last many hours
+longer."
+
+"Pass the little girl down to me," spoke Andy. "Then you jump. We'll
+save you all right."
+
+The little girl reached the deck in safety, and the woman, who proved to
+be her mother, followed.
+
+"Now take us to your ship," said the woman.
+
+"You must be a long way from her, as she is not in sight."
+
+"Our ship is right here," spoke Mr. Henderson with a smile.
+
+"Where, I don't see her," and the woman looked in all directions.
+
+"Allow me to introduce you to Profess Amos Henderson's famous submarine,
+the _Porpoise_," spoke the inventor with a bow. "But come, let us go
+below. You must be suffering, and here I am making speeches."
+
+"Indeed I am hungry, and thirsty too," said the woman. "So is Nellie.
+But I thought this was merely a small boat, sent from some large ship to
+get us."
+
+The woman and girl descended to the cabin of the submarine, where
+Washington set before them a fine meal. Under the advice of the
+professor they partook sparingly of food and drink at first, as, having
+eaten nothing in many hours, the inventor said they must begin by taking
+a little at a time.
+
+As soon as they had finished and become somewhat rested, the woman told
+her story. She was Mrs. Johnson, a widow, her husband having once owned
+and been captain of the schooner that was wrecked. After his death she
+and her daughter, having become part owners of the craft, disposing of
+a third interest to the former mate of the ship, had set out on one of
+the voyages to South American ports.
+
+They had had good weather going, and took on a valuable cargo of lumber
+and rare woods. But the return trip was more perilous. Heavy storms had
+buffeted the craft almost from the time of leaving port, and in one
+heavy blow, ten days before, the ship had been wrecked.
+
+"What became of the crew?" asked Mr. Henderson.
+
+"They took to the boats," replied Mrs. Johnson. "My little girl and
+myself were to go with the mate and his men. The waves were fearfully
+high, and, as they held the boat close to the schooner so we could get
+in, a big roller smashed the little craft. The men must have all been
+drowned for I never afterwards caught sight of one of them."
+
+"But the other boats?" asked the inventor.
+
+"They had gotten too far away to hail, supposing that I would be taken
+care of by the mate. There was nothing for Nellie and I to do but stay
+on board, expecting the ship to sink every minute."
+
+"And you have been there ever since?" inquired Andy.
+
+"Ever since. That was ten days ago. Every day I thought it would be our
+last. The storm passed away and the sea became calm but the ship kept
+settling lower and lower. Only the fact that part of the cargo was wood
+kept her afloat so long. I managed to get some provisions and water up
+on deck, but the sea had spoiled most of the stuff. We had to eat only a
+little at a time, as I knew it would be some days before we could be
+rescued, if we ever were. Two days ago we ate the last of the food and
+drank almost the last of the water."
+
+"Then you had nothing since then," spoke Jack.
+
+"Only a few drops of rain that I caught on a piece of sail," answered
+Mrs. Johnson.
+
+"Never mind, you can have all you want now, mother," said Nellie, coming
+over to pat her parent's cheek. "Oh," the child went on, "I was so
+thirsty I could just cry when I thought of such things as ice cream
+sodas."
+
+"I guess you could," agreed Mark. "Well, we can't give you any soda
+water, but we have plenty of the other kind."
+
+Mrs. Johnson was much interested in the _Porpoise_ and Professor
+Henderson showed her all about the craft. Though the quarters were
+rather cramped, a small cabin was fitted up for the lady and her
+daughter.
+
+"We will travel a bit under the water so you can get used to it," said
+the captain after a tour of the ship had been made. The tanks were
+filled, and the _Porpoise_ sank beneath the waves. At first Mrs. Johnson
+was much frightened, and Nellie cried. But when they saw how skillfully
+the ship was managed, and how easy it was to rise again, they lost their
+fears.
+
+For several days the voyage was continued. Mrs. Johnson and Nellie
+remained aboard as there was no place to land them, and they said they
+wished to stay until they met some ship sailing north.
+
+One day, just at dusk, when the _Porpoise_, after a long run under the
+water had come to the surface, the professor, came up on deck to take a
+look around. Washington and Andy accompanied him.
+
+"Looks like land, off there to the left," remarked the old hunter.
+
+"Get the glasses, Washington," said Mr. Henderson. "It may be a ship."
+
+He took a long and careful look through the binoculars.
+
+"It's some sort of land," he announced. "We'll go over in the morning
+and see what it is. Probably it's an island, for there's no main land in
+these parts. We are in the middle of the southern Atlantic now."
+
+The next morning, after breakfast, the _Porpoise_ was headed toward the
+dark spot on the surface of the water that the professor had gazed at
+the evening before. As they came nearer it was seen that the place was a
+large island.
+
+"But it's a mighty queer one," spoke Mr. Henderson. "It looks more like
+a big volcano than anything else."
+
+As the ship came nearer it was seen that this was true. The island rose
+abruptly from the surface of the sea in a big ridge, slightly rounded.
+There appeared to be no signs of life on the land, but in the air
+overhead hovered several big birds. These circled about and then
+fluttered down, seemingly about the middle of the island.
+
+"We'll sail around and see if there's a place to land," spoke the
+inventor. "There doesn't seem to be a good harbor on this side."
+
+Slowly the _Porpoise_ made the circuit. The island appeared to be almost
+round. When they had gone about half way around Andy, who was staring
+ahead, cried out:
+
+"Look out Professor! Don't go any nearer or we'll be sucked into the
+whirlpool!"
+
+The inventor looked where the hunter pointed. Then he beheld the
+strangest sight he had ever seen. The island was low toward where Andy
+pointed and they beheld the waters of the ocean pouring over the edge
+of it, and falling down into an immense hole with a roar like that of
+Niagara Falls.
+
+"Reverse the ship!" cried Professor Henderson. "Send her back quickly,
+Washington, or we'll be sucked down!"
+
+The colored man lost no time, and the big screw was sent whirling in the
+opposite direction. And it was high time, for already the onward rush of
+the falling waters was slowly drawing the ship toward the big cavern.
+
+"That was a lucky escape," commented Amos Henderson. "Well, as we can't
+land there we'll try the other way around."
+
+The ship was headed in the opposite direction, and, after an hour's
+sailing, a good harbor was discovered. The _Porpoise_ was anchored in
+shallow water close to the shore and in a small boat the professor, Andy
+and the two boys went to the strange island.
+
+They found it merely an immense circle of land with the middle part
+taken up by the big hole. And such a hole as it was! It was so wide
+across that they could not see the farther side, and the depth they
+could only guess at. Looking down they could only see great rolling
+masses of clouds or vapor.
+
+"Perhaps it's steam," suggested Jack.
+
+"Maybe it is," agreed the professor. "If this is a volcano, with lava in
+it, the water of the ocean, pouring in on the other side, may be changed
+to steam."
+
+"Do you suppose this hole leads to the centre of the earth?" asked Mark.
+"I've read somewhere, that the earth is hollow."
+
+"Some scientists believe it," commented the professor. "This looks like
+a big enough hole to lead clear through to China. Hark, you can hear the
+roar of the water now."
+
+They listened, and the wind brought to them the sound of the sea pouring
+down into the unfathomable depths.
+
+"Let's throw a big rock down," suggested Jack. "Maybe we can hear it
+strike bottom."
+
+With the aid of Mark he cast a big boulder down into the depths. They
+listened intently, but not the slightest sound echoed back.
+
+"I guess the bottom is too far away for you to hear the stone land,"
+said the professor.
+
+
+
+
+CHAPTER XVI
+
+THE GHOST AGAIN
+
+
+They spent some time looking down into the hole. The masses of vapor, or
+clouds, rolled and swirled hundreds of feet below them, but never broke
+sufficiently to allow of a clear sight.
+
+"Well, we had better go back to the ship," remarked the professor. "We
+must continue our voyage."
+
+They were soon on the _Porpoise_ and steaming away from the strange
+island, the inventor deciding to get far off out of the influence of the
+terrible waterfall.
+
+The night was, as usual, spent with the ship slowly steaming ahead on
+the surface of the water. It was getting on toward twelve o'clock and
+Washington had the watch. He was to be relieved by Jack.
+
+The latter had been awakened by the alarm clock at the head of his bed,
+which time-piece he had set to arouse him so that he might take
+Washington's place. Jack was just getting the sleep from his eyes by a
+vigorous rubbing when he heard a loud yell.
+
+"Land a' Massy!" cried Washington from the deck above. "I's goin' t' die
+suah! De ghostess am after me ag'in!"
+
+Without waiting to dress, Jack sprang up the ladder and was soon out on
+the deck. He saw Washington kneeling down in front of the conning tower
+door while, at the after end of the deck, was a mysterious white object;
+the same strange shape that had been observed before.
+
+"I'm going to solve this puzzle!" exclaimed Jack to himself as he made a
+dive toward the object in white. "This ghost business will have to
+stop!"
+
+But, unfortunately for his plans, his foot slipped on the smooth steel
+deck, and he went down in a heap. When he got up the ghost was nowhere
+to be seen.
+
+Washington, however, was still kneeling down and praying to be spared
+from the attack of the midnight visitor. Jack limped over to the colored
+man.
+
+"Keep still," said the boy. "It's gone now. What was it, anyhow?"
+
+"Some ghost from de grabeyard," replied Washington.
+
+"When did you see it first?" went on Jack.
+
+"'Bout ten minutes ago," replied Washington.
+
+"Well it's gone now," said Jack, though he had to admit to himself that
+the affair was somewhat puzzling. Professor Henderson had been awakened
+by the yells of the colored man and came on deck to see what the trouble
+was. He appeared somewhat annoyed when Washington told him what had
+happened.
+
+"There are no ghosts!" declared the inventor in positive tones.
+
+"You wouldn't say so, Perfessor, if you'd seen him," spoke Washington.
+"He were all in white, tall an' slim, an' big red eyes, an' a green
+nose, an' fire comin' from his mouth an'--"
+
+"Nonsense," interrupted Jack. "It was nothing but a white object,
+Professor Henderson. I saw it."
+
+"And what do you think it was?" asked the inventor.
+
+"I--I can hardly say," replied Jack. "Of course I don't believe in
+ghosts, but this--"
+
+"It was probably a mist from the ocean," interrupted the professor.
+"Don't let me hear any more of it. Washington, go below. Your watch is
+up and Jack will take charge. I don't believe there will be any more
+ghosts."
+
+Nor were there that night. The _Porpoise_ glided along, requiring little
+attention, and when morning broke was several miles nearer the southern
+pole.
+
+The journey was continued beneath the waves and it was found much cooler
+under them than upon the surface, for the ship was in the midst of the
+equatorial heat.
+
+About four o'clock in the afternoon, when all was quiet aboard, there
+came a sudden yell from the engine room. Washington's voice could be
+heard calling for help. Then it died away in a groan.
+
+"Something has happened!" called Jack. "Washington is in trouble."
+
+He hurried toward where the machinery could be heard buzzing. The
+professor, with Andy and Mark followed. They expected to see the colored
+man caught in some shaft or belt, but he was nowhere in sight.
+
+"Perhaps he has fallen into the ocean," suggested Mark.
+
+"The engine room does not open into the sea," answered the professor.
+
+A deep groan came from some corner of the engine room.
+
+"There he is!" cried Jack.
+
+But a careful search failed to reveal Washington. Still he could be
+heard to groan at intervals. Bill and Tom came and aided in the search,
+while Mrs. Johnson, who was worried at the unusual activity, asked what
+the trouble was.
+
+Captain Henderson did not tell her, for, as he said afterward, he did
+not want any women fainting away on his ship. At his request Mrs.
+Johnson went back to her cabin, and the hunt for Washington continued.
+
+"Here he is!" cried Jack at last.
+
+The boy had climbed up on a small ladder that led to the big storage
+battery tanks. He had looked down, and there, in the large metal box had
+spied the colored man on the bottom. Washington was unconscious and
+breathing heavily.
+
+"He has been overcome by the fumes of the sulphuric acid!" exclaimed the
+professor. "We must get him out quickly or he will die!"
+
+"I'll get him!" cried Andy.
+
+The old hunter grabbed a small step ladder that stood against the wall
+of the engine room. With this on his shoulder he climbed up the steps
+which led to the top of the storage battery tank. Then, by means of his
+ladder, he descended inside.
+
+He had to work quickly as the fumes were very strong, but he managed to
+hoist Washington up so that Bill and Tom, from outside, could take hold
+of him. Then the colored man was carried out on the deck, where the
+fresh air and some restoratives the professor used soon revived him.
+
+"Is I dead," were Washington's first words, as he sat up and looked
+about him.
+
+"Not this time," replied the professor. "You had a close call, though.
+How did it happen?"
+
+Washington explained that he started to clean the battery tank, when he
+lost his balance and fell in. He cried as he felt himself falling, but
+as soon as he struck the bottom of the tank the fumes of the chemicals
+made him unconscious. His deep breathing, which had sounded like groans,
+alone served to attract attention to his location.
+
+In a little while Washington was all right save for a slight weakness.
+Captain Henderson made him go to his bunk, and ordered him to remain
+there until morning.
+
+During the excitement over Washington's mishap all thought of steering
+the ship had been forgotten, and when Mr. Henderson went to the conning
+tower about five o'clock he found that the _Porpoise_ was several points
+off her course and was headed to the east instead of to the south. How
+many miles out of her way the craft had steamed could only be guessed,
+but as she had been going wrong for nearly an hour, it must be quite a
+few the inventor calculated.
+
+However, he said, no great harm had been done. Even this slight accident
+would not have happened had not Bill, who was in the conning tower
+steering, forgotten to put the automatic device in operation when he
+left the wheel to join in the search for Washington.
+
+"We'll soon make up the lost ground," said Mr. Henderson. "Another week
+or ten days ought to see us at the end of our journey."
+
+"And what will we do when we get there?" asked Jack.
+
+"We will make some important geographical and scientific observations,"
+said the professor. "Not only that, but we will have done something that
+no living person has ever accomplished. We reached the north pole,
+though we could not land on the exact spot. Let us hope we will be more
+successful regarding the south pole."
+
+The professor set the ship on her course again. Bill and Tom got supper
+in place of Washington, while Mrs. Johnson helped set the table.
+
+The meal was eaten, and then the inventor started the ship toward the
+surface, following the plan of not sailing beneath the waves after dark,
+in order to avoid accidents.
+
+The craft was making good speed ahead, with the big screw revolving in
+the tunnel and spurting the water from the rear, when there came a
+sudden jar, and everyone nearly toppled over from the quick stopping of
+the _Porpoise_. At the same time the forward end seemed to go up in the
+air.
+
+"What has happened? Are we sinking?" cried Mrs. Johnson.
+
+"I think we are going up," spoke the professor in cool tones.
+
+"In the air?" asked the lady.
+
+"On the land," answered the inventor. "I think we have struck shore and
+slid up on a beach."
+
+He ordered the engine stopped and hurried to the conning tower to make
+an observation. He turned on the searchlight and looked carefully at
+what the beams showed. Then he came back to the cabin.
+
+"Well, what is it?" asked Mrs. Johnson.
+
+"We have gone ashore, just as I supposed," said Mr. Henderson.
+
+"And whereabouts are we?"
+
+"On the coast of South America."
+
+"Near where?"
+
+"Near Terra Del Fuego, the land of fire!"
+
+
+
+
+CHAPTER XVII
+
+ATTACKED BY SAVAGES
+
+
+"Are we in any danger?" asked Mrs. Johnson.
+
+"I hope not," replied the captain. "If the ship is not strained the
+rising tide will probably float her safely, and we can continue our
+trip. We will have to wait until morning to see, however."
+
+"And if the ship is damaged?"
+
+"We will have to do what we can. We will hope for the best, madam."
+
+The professor went on deck. His first opinion of the accident was
+confirmed. The _Porpoise_, in emerging from the waves, had slid well up
+on a sandy shore, where she was held fast because the tide was rapidly
+falling. It would be twelve hours before there would be a chance of her
+floating again.
+
+The mishap had occurred because the ship had gotten off her course when
+Washington's accident occurred, and had not been set right in time.
+
+However, as Mr. Henderson had said, there was no particular danger,
+unless it was found that some of the plates had been strained, which
+might cause a leak.
+
+The night was passed with the nose of the _Porpoise_ well up on shore,
+and before morning, as the tide continued to fall, more and more of the
+craft became exposed until the whole steel body rested on the sloping
+beach.
+
+Jack was the first to awaken. He was up with the sun, and went out on
+the deck to take a view of the country he had often heard about. A
+stretch of wild landscape met his eyes, and to the left and right of the
+ship the waves were breaking on jagged rocks.
+
+"It's a good thing we didn't hit the rocks," thought the youth.
+
+Mark came up on deck, and the two boys looked over the scene. It was a
+strange one. Beyond the beach was a low level country, green in places,
+with now and then a patch of what looked like trees.
+
+"And what are those brown spots moving about?" asked Mark.
+
+"I guess they are herds of cattle," replied Jack. "You know South
+America is a great place for them."
+
+For half an hour the two lads gazed about. Except for the stern of the
+_Porpoise_ all of the craft was now out of water, and one could have
+jumped from the low deck down to a mound of white sand of the beach.
+
+"Let's go ashore and take a run," suggested Mark. "I've almost forgotten
+how to walk on dry land."
+
+"Go ahead," answered Jack. "I'm with you."
+
+"All right."
+
+The boys lost no time in getting down to the beach. They found it hard
+and firm, and made their way to the strip of grass-covered land lying
+beyond. Up and down they wandered, finding many curious and beautifully
+marked shells where the waves had washed them.
+
+Suddenly Jack gave a big jump and let out a yell.
+
+"What's the matter?" asked Mark.
+
+"I thought I saw one of those cocoanuts move," answered Jack, pointing
+to where several of the big shaggy fruits lay under a tree from which
+they had fallen.
+
+"I guess you're right," spoke Mark. "I certainly saw one of them take a
+little side step. I wonder what does it."
+
+As the boys watched they were surprised, to see one of the cocoanuts
+come toward them, apparently advancing without any visible means of
+locomotion.
+
+"This is a queer country," remarked Jack, getting ready to run in case
+the strangely moving cocoanut might be a warning of danger.
+
+"Look! There's a whole lot of them moving," cried Mark.
+
+Sure enough a dozen or more of the nuts began to advance toward the
+lads. The boys were not so much afraid as they were surprised. But a few
+seconds later the reason for the strange sight was made plain.
+
+As they looked they saw one of the nuts roll down a little mound of
+sand. Then they noticed that a big land crab was on the tiny hill and it
+was evident that the nut had fallen from his claws.
+
+"It's the crabs!" exclaimed Mark. "I remember reading about them now.
+They come ashore from the water where they live part of the time and get
+the cocoanuts. Then they smash the shells by pounding the nuts on a
+stone and eat the white meat inside. They are called cocoanut crabs."
+
+"I was beginning to think we were in some enchanted land," spoke Jack.
+
+"Well, it certainly looked queer," agreed Mark.
+
+For some time the boys watched the strange sight. Then they walked along
+the beach, seeing several large star fish, and some big horse-shoe crabs
+that had been stranded by the tide.
+
+"Look at that immense turtle!" exclaimed Mark, as one of the creatures
+scuttled over the sand toward the sea. "I'll bet she's been laying
+eggs!"
+
+"Perhaps so."
+
+They made a rush for the tortoise but were not quick enough, for she
+slid into the water and made off.
+
+"Here's her nest, anyhow," called Jack, as he pointed to some eggs,
+thinly covered with sand. "Let's go back and take them with us. I've
+heard they are good eating."
+
+Jack and Mark started to gather up as many of the eggs as they could in
+their hats. While they were thus engaged they heard a call from the ship
+and looked up to see coming toward them, all of the ship's company
+except Washington.
+
+"I wonder if anything could have happened," spoke Mark.
+
+He and Jack dropped the eggs and started on a run toward the stranded
+ship. They were reassured, however, when they saw the professor waving
+his hand at them. When he got within hailing distance the inventor
+called:
+
+"It's all right, boys. We're just taking a little walk, before
+breakfast, for an appetizer. It's been some time since we were on land.
+Washington says he'll have some fine fried ham for us in a little
+while."
+
+"And here are the eggs to go with it," spoke Jack.
+
+"Have you found a hen house?" asked Mr. Henderson in some wonder.
+
+"No, but we discovered a turtle, which is just as good," replied Mark.
+The professor agreed with him, and called for Washington to come and get
+the eggs.
+
+"Wall I 'clare to goodness!" exclaimed the colored man as he gathered
+the product of the turtle up in his cook's apron. "Dis suttinly am a
+queer contraption of a country to find eggs growin' in de sand."
+
+He shuffled back to the ship, while the others walked up and down on the
+beach. In about half an hour the professor suggested that they return.
+
+"Washington must have breakfast ready by now," he said, "and I, for one,
+am hungry enough to enjoy it."
+
+They turned toward the stranded _Porpoise_ but no sooner had their eyes
+taken in the sweep of the ocean that lay before them than they uttered
+cries of fear.
+
+Spreading out from the beach in a big half circle that enclosed within
+its curve the submarine, were three score of canoes, each one filled
+with half naked savages.
+
+"The natives are going to attack the ship!" cried the professor. "We
+must hurry back or we are lost!"
+
+He started on the run, accompanied by the boys and men. Mrs. Johnson and
+her daughter brought up the rear. The adventurers had gone from one
+misfortune into another.
+
+At the top of their speed they approached the stranded ship. The natives
+saw them coming and the next instant hundreds of paddles broke the waves
+into a mass of sparkling water as the wily savages urged their canoes
+swiftly toward the submarine.
+
+"If we can only reach it first we can hold them off until the tide
+floats us, and then we can escape," said the professor.
+
+He increased his pace though the run was beginning to tell on his aged
+frame. The adventurers were now within an eighth of a mile of the ship,
+but the savages were closer, and had the advantage of being able to make
+greater speed. The two forces approached nearer and nearer. Finally the
+first of the canoes reached the submerged end of the _Porpoise_.
+
+With wild shouts a score of the brown men leaped from the boats and
+scrambled up the steel sides. An instant later they were joined by
+several canoe loads of their companions. They swarmed up on the deck,
+and some peered down the winding stairs that led to the interior of the
+ship.
+
+"Too late!" cried the professor. "They have captured the _Porpoise_!"
+
+"But Washington is aboard!" shouted Jack.
+
+As he spoke the colored man was seen clambering up out of the companion
+way. He gave one look at the wild natives who swarmed over the ship, and
+then, with a yell to be heard a long way off, disappeared below.
+
+The shouts and cries of the savages grew louder and they seemed to be
+doing a sort of war dance.
+
+"We must make one effort to drive them away," said the professor in
+desperation.
+
+"We haven't even a revolver," spoke Andy.
+
+"Let's use stones," suggested Jack, grabbing up a handful from the
+beach.
+
+"Look out!" yelled Mark. "They are going to shoot some arrows!"
+
+A second later a flight of the weapons filled the air. Fortunately the
+natives were too far away to permit the shots taking effect, but it
+showed that they intend to fight and take possession of the ship.
+
+Even this did not frighten Mr. Henderson. His vessel was more than life
+to him and he kept on. Several arrows fell dangerously close and he
+might have been hurt had not old Andy run after him and induced him to
+go farther up the beach and out of harm's way.
+
+"They will kill Washington!" cried Jack as he thought of the colored man
+at the mercy of the savages.
+
+"There he comes!" yelled Mark.
+
+He pointed toward the ship and as they all looked in that direction they
+saw the colored man climbing out on the deck. Under one arm he bore a
+long narrow box, and in the other hand he carried one of the electric
+guns.
+
+"He's goin' to fight 'em!" exclaimed Andy. "He's got a gun and he will
+show 'em what's what!"
+
+But Washington did not seem to have any such intentions. With a yell
+that equalled the savage cries of the natives, he sprang over the side
+of the ship, onto the sand and ran toward the group of adventurers. A
+flight of arrows followed him, but he was not hit.
+
+
+
+
+CHAPTER XVIII
+
+ON LAND
+
+
+"Why don't he shoot his gun at 'em?" demanded Andy, capering about on
+the sand. "He could soon scare 'em off!"
+
+"I'm afraid Washington is too frightened to do anything like that,"
+answered Professor Henderson. "He is lucky to have escaped alive."
+
+"Wait until he gets here with that gun, an' I'll do some huntin' that
+will make them savages skip!" exclaimed Andy.
+
+In a little while Washington came up to where the others from the
+_Porpoise_ stood on the beach. The colored man was panting from his run.
+
+"De most monstrous disproportionately extradition ob circumstantial
+occurrances dat ever transpositioned on my optical vasionariness!" he
+exclaimed as he laid his gun and the black box carefully down on the
+sand. "Ten thousand naked imps of darkness swarmin' ober de ship an' not
+a pusson to say what dey ought to do an' where dey ought t' go! It am
+suttinly terrible!"
+
+"Why didn't you shoot some of 'em?" demanded Andy.
+
+"Me?" exclaimed Washington. "What for I want t' shoot 'em? S'pose I want
+'em t' git mad at me?"
+
+"Well, you're a great one," went on Andy, picking up the gun. "I guess
+I'll have to take a few shots myself."
+
+"Yes, sah."
+
+From Washington the adventurers learned how the savages had silently
+come up in their canoes and surrounded the ship, gaining possession of
+it before he could make any effort at defense, even had he so desired.
+
+"What are we to do now?" asked Mrs. Johnson, when they had retreated out
+of sight of the savages. "The natives have possession of the boat, and
+how are we to regain her when there are so many of them?"
+
+"It certainly is a hard nut to crack," admitted the professor. "We will
+have to camp out on the beach for a while and see what happens. Perhaps
+they may leave the vessel when they find it will do them no good. They
+can't run her."
+
+"But they can tear her all apart and damage the machinery," said Jack.
+"Then we would be in a pickle."
+
+"Well, we won't hope for any such bad luck as that," interrupted the
+professor. "We will look for the best."
+
+"When are we going to have breakfast?" asked the little girl, after a
+long wait. "I'm hungry, mother."
+
+"We will have it pretty soon," replied Mrs. Johnson in order to quiet
+her daughter's mind.
+
+"But I want it now," continued Nellie. "I'm very hungry."
+
+"Hush!" said Mrs. Johnson.
+
+"An' I had de finest brekfust what was ever invented," said Washington,
+rolling his big eyes. "Mud turkle eggs, ham, preserves, coffee--"
+
+"That will do, Washington," said the professor. "It only makes our
+mouths water to think about such things."
+
+At the mention of the turtle eggs Jack nudged Mark, and signalled him to
+walk to one side. When they were out of earshot of the others Jack said:
+
+"What's the matter with cooking some of the eggs that are left on the
+sand? There are plenty of them, and there is no sense in our going
+hungry."
+
+"How you going to cook 'em?" asked Mark.
+
+"I'll show you," replied Jack.
+
+He scooped a hollow place out in the sand until he had quite a hole.
+This he banked up with stones until he had a small oven. By arching the
+stones over toward the top there was left a sort of circular opening.
+Over this Jack fitted a monster clam shell, with the concave side
+uppermost.
+
+This made an improvised stew pan. Underneath was piled small bits of dry
+drift-wood, which a match soon set on fire. In a little while the water
+in the big shell was boiling.
+
+"Now get some other shells for dishes," said Jack to Mark.
+
+Soon Mark had piled up a lot of smaller shells.
+
+"Help me gather some eggs now," said Jack, "and we'll put them in to
+boil. Then we'll invite the rest of the folks to breakfast."
+
+The two boys soon uncovered from the sand a pile of the eggs, and in a
+little while they were steaming in the hot water. Then Jack arranged the
+shell-dishes on the sand. He went over to where the others were gloomily
+considering their plight.
+
+"Breakfast is ready," he announced.
+
+"This isn't any time for joking," spoke Professor Henderson, rather
+sternly.
+
+"But I mean it," went on Jack. "Just come over and see. I'm not fooling
+you."
+
+Wondering what he had done they all followed him.
+
+"Welcome to Hotel Terra del Fuego!" cried Mark. "We haven't much of a
+variety, but what there is we can recommend."
+
+He began to dip the eggs out of the water with a bit of shell and placed
+them on the improvised dishes.
+
+"Everyone sit down," commanded Jack. "The bill of fare is ready."
+
+They all joined in the short laugh that followed, and soon were seated
+in a circle about the beach-oven. The eggs proved to be very good, even
+though there was no pepper. The salt of the sea water they were boiled
+in was more than sufficient.
+
+"Now if there was only bread in that ammunition bag Washington brought
+with the gun," said Andy, "we wouldn't want a better meal."
+
+"He'p yo'se'f!" exclaimed the colored man with a grin as he extended a
+canvas bag that was tied to the stock of the electric gun.
+
+The old hunter opened it and found it filled with ship biscuits.
+
+"Well I am stumped!" he exclaimed.
+
+"I grabbed up de wrong thing in my haste," Washington explained. "I
+thought I had de electrical lightning bullets, but I didn't. Howsomever
+de gun's got some in de chamber."
+
+"It's a lucky mistake," commented the professor as he munched a biscuit
+and an egg. "Bullets are good but these are better, when one is
+hungry."
+
+They managed to make a fairly good meal, so that even hungry Nellie was
+satisfied. The boys found a spring of fresh water up on shore, and this
+furnished something to drink, for which they were grateful.
+
+They sat about on the beach, after the breakfast and discussed what they
+had better do. It was evident that an attempt to regain possession of
+the ship, with their small force and only one weapon, was out of the
+question.
+
+"We've got to use strategy," said Andy. "If we could play some trick on
+the savages we might scare them away. Otherwise I don't see what we are
+to do."
+
+"It's a bad state of affairs," replied professor Henderson. "Even if we
+got the ship we might find it so badly damaged that it would be
+impossible to run it. It is a terrible thing," and he heaved a deep
+sigh.
+
+The hours passed with no change in the situation. The savages remained
+in possession of the submarine, and did not seem inclined to quit the
+vessel. Most of them were inside, but quite a number paddled about the
+stranded craft in their canoes.
+
+There was nothing for the adventurers to do but to await developments.
+With no chance of attacking the force of natives, they might consider
+themselves lucky if the savages did not come ashore to give battle.
+
+The sun was high in the heavens when, in the shade of a big tree where
+they had all taken refuge from the heat, Nellie again announced that she
+was hungry.
+
+"I guess the boys will have to provide another meal," said Mr.
+Henderson.
+
+Jack and Mark said they guessed they could find some more turtle eggs,
+and Washington volunteered to accompany them. As they were looking for a
+nest in the sand they saw one of the tortoises scurrying down to the
+ocean.
+
+"Git her, quick!" cried the colored man. "Turn her ober on her back!"
+
+The boys did so, though they did not know what Washington's object was.
+The big animal lay bottom side up, vainly moving its flippers. In a few
+minutes Washington had killed the turtle and cut it out of the shell.
+
+"Now we'll hab turtle soup!" he exclaimed.
+
+Soon the fire was again blazing in the improvised stove, and a little
+later an appetizing smell filled the air. Washington had made the soup,
+and, in addition, had cooked a number of the turtle eggs.
+
+Big clam shells again served for dishes and a better meal than the
+breakfast was served.
+
+"Now if we only had some dessert," spoke Mr. Henderson in a joking
+tone, "we wouldn't want much more. But I suppose dessert is out of the
+question."
+
+Jack and Mark looked at each other and, without a word went off toward
+the woods. In a little while they came back, their arms filled with
+cocoanuts.
+
+"How will these do for dessert?" asked Jack.
+
+"Fine!" cried Mr. Henderson.
+
+The fruit was broken open with stones and the delicious milk and soft
+pulp eaten with much relish. Then the adventurers stretched out beneath
+the trees and rested. The thoughts of each one were busy with plans for
+recovering the submarine, though no one seemed to be able to suggest any
+thing.
+
+It was getting dusk, when, somewhat discouraged over the result of the
+visit of the savages, they were all seated on the beach. They were
+beginning to think again of something to eat when Andy Sudds, discovered
+the long black box which Washington had brought with him in his flight
+from the _Porpoise_, and dropped in a hollow.
+
+"I suppose you've got something very fine in there, Washington?"
+
+"I declare to goodness I don't know what dat air contraption am
+conglomerated with," said the colored man. "I jest grabbed it up and
+run."
+
+The old hunter had, in the meanwhile, taken the cover off.
+
+"What in the world have we struck," he exclaimed.
+
+"Sky rockets!" cried Jack, with a glance at the contents of the box.
+
+"Yes," said Professor Henderson. "I took some aboard in case we might
+have to signal for help on the water."
+
+"Hurrah!" yelled Andy.
+
+"What's the matter?" asked Jack.
+
+"We'll use the sky rockets as weapons against the natives!" shouted the
+old hunter, capering about on the sand.
+
+
+
+
+CHAPTER XIX
+
+REGAINING THE SHIP
+
+
+At first the others did not know what he meant. Andy seemed much
+excited, and for a time the professor thought the heat and worry might
+have affected the hunter's mind.
+
+"We'll show 'em a thing or two!" cried Andy. "I once scared a lot of
+Indians this way so they didn't know whether they were on their head or
+their feet. Hurrah!"
+
+"What are you talking about?" asked Mr. Henderson. "Hadn't you better
+sit down and rest a bit?"
+
+"I'm all right," replied Andy. "I'm talking about those sky rockets.
+They'll be better than bullets. You see," he went on, "after it gets
+dark we'll shoot the rockets over the ship. The savages will think they
+are in the midst of a lot of falling stars, and if they don't take to
+their boats and leave us the ship I'll miss my guess, that's all."
+
+"Good!" exclaimed the inventor. "We'll try it."
+
+The rockets were taken out and examined. They were big affairs of
+several pound weight and were intended for far-off signalling at sea.
+
+Andy, with the aid of the boys, Tom and Bill, soon constructed a rough
+sort of support from which to set off the fire-works. As soon as it grew
+dark, which it did about seven o'clock, preparations were made to try
+the experiment.
+
+With a whizz and roar the first rocket went sailing skyward. Up through
+the black night it went, trailing behind it a shower of fire and sparks.
+Then, with a loud report like that of a gun it burst directly over the
+ship and a rain of brilliantly colored globes of flame descended.
+
+"Shot number one!" cried Andy, who was setting off the rockets.
+
+For a few seconds after the first flight there came no sound from the
+natives at the ship. Then, just as the second rocket was set off there
+issued a long-drawn howl, which was succeeded by cries of fear.
+
+"We've waked 'em up!" shouted Jack.
+
+In rapid succession several more rockets were sent over the _Porpoise_.
+By the light of them could be seen a mass of natives crowded out on the
+small deck, while others were in their canoes.
+
+"I think I'll try it a little lower this time," remarked Andy. "Maybe I
+can hit some of 'em!"
+
+He slanted the support closer to the ground and set off two rockets at
+once. Straight across the sandy beach they flew, directly toward the
+crowd of natives on the ship. Right into the midst of the savages the
+trailing comet of fire shot, with a hiss, roar and sputter that was
+enough to strike terror into the bravest heart.
+
+There was a long piercing howl of fear. Then, as the natives felt the
+hot sparks scatter over their half-naked bodies, they broke into a wild
+stampede. Over the side of the ship they plunged, into the sea, and swam
+off. Those in boats paddled quickly away.
+
+For good measure Andy sent another rocket into the midst of the fleeing
+ones, and this served to quicken their departure. By the light of the
+last one it could be seen that the ship was deserted, though the water
+all about her was black with the swimming savages, and the canoes.
+
+"I guess they won't come back in a hurry!" cried Andy. "Come on! We'll
+board the ship now, and get the electric guns to ward off any further
+attacks!"
+
+"That's the talk!" cried Mark.
+
+Toward the _Porpoise_ all started on a run. As they neared her they
+found that the rising tide had floated her.
+
+"We must see if the natives damaged her," spoke Mr. Henderson as soon as
+he set foot on deck. "If they have it will be a hard matter to make
+repairs so far from civilization."
+
+A hasty examination, however, showed that the savages had disturbed
+little. The engine was soon set in motion, and, in ten minutes the ship
+was steaming away from the coast, headed toward the south, the goal they
+were so eagerly seeking.
+
+As soon as they were well out to sea, and all sight of the canoes of the
+savages had been lost, supper was served, and all brought good appetites
+to the table. For, though the improvised meals on shore had tasted good,
+there had not been much to them.
+
+For several days the _Porpoise_ was kept on her course, sailing along
+under the water by day, and upon the surface at night. It was one
+pleasant afternoon, while Nellie, Jack and Mark were sitting out on the
+deck, during one of the times when the boat had risen to the surface to
+renew the air supply, that a strange commotion was observed off their
+lee. The ocean seemed to be boiling.
+
+"What is that?" asked the little girl.
+
+The two boys looked to where she pointed. Indeed the ocean seemed to be
+bubbling up and down in a strange manner.
+
+"It's a school of porpoises," said Jack.
+
+Just then the water became alive with big fish. They leaped over each
+other, springing high into the air and falling back into the sea with
+resounding splashes.
+
+"They're not porpoises! They're whales! Baby whales!" yelled Mark. "Look
+out or some of the big ones may ram the boat!"
+
+As he spoke the water all about the submarine was seen to be fairly
+swarming with the small whales. There were scores of them, and, at
+times, they were so thick that it appeared possible to walk out upon
+them without getting very deep into the water.
+
+Suddenly the ship careened to one side and the sea rushed over the deck.
+It was evident that one of the big whales, which were deeper down in the
+water, had struck the vessel.
+
+Nellie screamed and tried to grab the hand rail that was about the
+platform. She missed her grip. The next instant she was floundering in
+the ocean, in the midst of the school of whales.
+
+"Man overboard!" yelled Jack, remembering vaguely that he had read this
+was the proper call to make in case of accident.
+
+His cry brought Washington and the professor up the companionway on the
+jump.
+
+"Launch the boat!" cried the inventor as he saw what had happened.
+
+Mark was already in action. At the first sight of Nellie slipping over
+the side he had thrown off his coat, broken the laces of his shoes in
+order the more quickly to remove the foot coverings, and had dived into
+the swirling water which surrounded the submarine.
+
+He struck out in the direction where the little girl had disappeared,
+and as her golden head appeared above the mass of foam he yelled in
+encouragement.
+
+By this time the small boat was launched and the colored man and Jack
+were pulling toward him. Mark succeeded in reaching Nellie as she was
+going down the second time. He grabbed her long locks and managed to
+keep her up until the little craft was alongside of him.
+
+"Git in quick, 'fore dem whales eat yo' up!" cried Washington.
+
+He hauled the unconscious child in first, and then Jack gave Mark a
+hand. As if by magic all the whales had disappeared and the sea was
+quiet again. In a few minutes the rescuers and the rescued one went back
+again on the _Porpoise_, where Professor Henderson soon brought Nellie
+around again. Beyond the shock and wetting neither she nor Mark was
+harmed.
+
+It was Jack's watch on deck that night. He had the tour from eight until
+twelve o'clock and when, about ten, every one but himself had retired,
+he took his position in the door of the conning tower and prepared to
+pass the time as best he could.
+
+The ship was moving along at half speed, and, as the automatic steering
+attachment was working Jack had little to do. He sat looking at the
+stars that twinkled in the sky, the blazing Southern Cross showing among
+the constellations, when he heard a slight noise near the companionway.
+
+He looked in that direction and, to his horror, he saw the ghostly white
+shape that had, on previous occasions, caused him and the others fright.
+
+At first the boy resolved to shut himself up in the tower and wait until
+the uncanny thing had disappeared. Then his courage came back and he
+thought he would try to solve the mystery.
+
+He argued that if the weird white object was human and could witness his
+movements the best thing to do would be to try and creep upon it
+unobserved. On the contrary, if the ghost was some natural phenomenon,
+or a supernatural agent, all he could do would be of no avail.
+
+So he decided the best thing to do would be to crawl upon the thing,
+keeping as near to the deck as possible and trying to hide himself. With
+this in view he put on a long rain coat that hung in the conning tower,
+and then, like a snake, commenced to wiggle his way toward the middle of
+the platform where the white object still stood.
+
+Nearer and nearer to it Jack came. His heart was beating fast and he was
+much frightened, but he nerved himself to continue. As he came closer he
+could see that the object looked more and more like a man, completely
+robed in white garments.
+
+Jack was now within ten feet of the strange object. It was a man, he was
+sure of it, but whether a present or former inhabitant of the earth he
+could not decide. Jack's hair was beginning to raise. A cold shiver ran
+down his spine as the white thing lifted an arm and seemed to point
+directly at him. At the same time it groaned in a deep tone.
+
+Jack let out a yell that could be heard all over the ship. He made a
+spring for the object, determined to discover what it was or die.
+
+At that instant the whole ship seemed to rise in the air. It left the
+water and began moving skyward. Right out of the waves the _Porpoise_
+was lifted until the big screw was clear of the water and it was
+churning around in the tunnel without any resistance, racing at top
+speed now that it had no water to thrust against.
+
+Then the ghost seemed to vanish into thin air, and Jack felt himself
+falling down the hatchway.
+
+
+
+
+CHAPTER XX
+
+ON A VOLCANIC ISLAND
+
+
+In an instant the ship was in confusion. The professor, followed by old
+Andy, Washington, Mark, Bill and Tom, came rushing from their berths,
+all in their night clothing, to see what the trouble was. They met in a
+tangled mass, stumbling over Jack at the foot of the steps.
+
+"Is the ship on fire?" called Mrs. Johnson from her cabin.
+
+"I hope not!" called the professor. "But something has happened. Don't
+be frightened!"
+
+By this time Jack, who had been somewhat stunned, recovered his senses
+and worked his way out of the mass of bodies.
+
+"The ghost! The ghost!" he cried. "I saw him again!"
+
+"Land a' massy!" yelled Washington.
+
+"What has happened to the ship?" cried the professor. "Is it a tidal
+wave?"
+
+"I was on deck," panted Jack. "I saw the white thing! I crept up on it!
+All at once the ship rose in the air!"
+
+"And it's still rising!" shouted the inventor. "I must see what this
+means!"
+
+He made his way to the deck, and his loud shout soon brought the others
+up to him.
+
+"Shut off the engine!" Mr. Henderson called down to Washington, who
+hurried to obey.
+
+"What has happened?" asked Andy, rushing towards him.
+
+"We have run upon an island," answered the professor. "This is the worst
+thing that has yet happened to us."
+
+"What sort of an island is it that shoots you up in the air?" asked the
+old hunter.
+
+"It's hard to say," replied Mr. Henderson. "We will have to wait until
+morning to find out."
+
+The boys and men went up on deck and there beheld a curious sight. The
+_Porpoise_ had been lifted bodily from the surface of the ocean where
+she had been sailing and was now raised about ten feet above the crest
+of the billows. It was too dark to see the extent of the island she
+rested on, but, from the circle of foam around the outer edge it did not
+appear to be very big.
+
+The excitement occasioned by the appearance of the ghost, Jack's yells
+and fall, and the rising of the ship, had subsided somewhat. Mrs.
+Johnson and her daughter, who were much frightened, were assured there
+was no immediate danger, and the men and boys put on more substantial
+clothing than that of their night robes.
+
+It seemed as if morning would never come, but at length there was a pale
+light in the east and soon it changed to a rosy glow, showing that the
+sun was coming.
+
+The professor was early on deck, and Mark and Jack were not far behind.
+As soon as it was light enough they could see that the ship was held
+fast on top of a small rocky isle, about one hundred feet in diameter,
+which rose abruptly from the water.
+
+"It's a volcanic island," decided the professor. "We are in the midst of
+subterranean disturbances and this is probably one of the effects of
+some under-sea eruption. The pinnacle of rock rose from the ocean,
+forced up by some power underneath, just as our ship came over it. That
+accounts for the sudden rising into the air of the _Porpoise_. No wonder
+we were all scared."
+
+"The next question," began old Andy, "is how are we to get off?"
+
+"That's the point," agreed Mr. Henderson. "Here we are, high and dry,
+and we might as well be a broken flying machine as a submarine for all
+the power we have."
+
+"Will we have to stay here forever?" asked Nellie, who had come up on
+deck.
+
+"I hope not," answered the professor, smiling for the first time since
+the accident. "We will find a way to get down, never fear, little girl."
+
+"I suppose we might dig some sort of a canal down to the water,"
+remarked Jack. "If we could we might float the ship."
+
+"I'm afraid you'd find it slow digging through this volcanic rock,"
+answered Andy. "It's like flint."
+
+"Well, there's no use worrying over it," went on the professor in as
+calm a tone as he could muster. "It's time for breakfast, and we have to
+eat whether we're on the top of an island that shoots out of the water
+when you least expect it, or sailing along as we ought to."
+
+Accordingly Washington prepared the morning meal, and they all found
+they had appetites for it, in spite of their fright. Afterward they all
+came on deck again and looked about them.
+
+They were in the midst of a wild waste of water. Not a sign of land
+could be seen in any direction, and there was no evidence of a sail or
+steamship as far as the horizon showed.
+
+The little island which held the _Porpoise_ so close a prisoner was a
+mere speck in the vast ocean, but it was large enough to put an end,
+temporarily at least, to the progress of the powerful submarine.
+
+The professor and the boys went over the side and climbed down to the
+rock. Then the inventor verified his surmise that the rocky point was of
+volcanic origin. It was also seen that there was little chance to get
+the craft back into the ocean.
+
+"I guess we're doomed to stick here for some time," remarked Mr.
+Henderson, with a grim smile. "The rock has caught us squarely and
+nothing short of dynamite will free us. To use the explosive might mean
+the destruction of the ship, and I dare not risk it."
+
+Gloom settled over the party in spite of the efforts the professor made
+to be cheerful. Washington, after the first few minutes of fright,
+regained his usual good spirits, but, no matter how he laughed and
+joked, there was a feeling of terror in every heart.
+
+They realized their helplessness, and knew that unless another upheaval
+of nature occurred there was small likelihood of their release.
+
+On the third day of their strange adventure Professor Henderson resolved
+on a bold step.
+
+"We must use dynamite," he declared. "If we stay here on this desolate
+rock we are bound to perish sooner or later, for our food cannot last
+many months, though we have a large supply. We are out of the path of
+steamers and only by chance would one pass here. With care we may be
+able to blast the rock so that the ship will not be permanently
+damaged. What do you all say? I would like your advice, for this
+concerns all of us."
+
+One after the other all said they were willing to abide by whatever the
+inventor did. Accordingly he made his preparations. Washington, with a
+hammer and chisel, was set to cutting a fair sized hole in the big rock,
+as far away from the ship as possible.
+
+He was two days at the job, and, during this time those on the stranded
+_Porpoise_ watched in vain for the sight of a vessel.
+
+"I am going to put the dynamite in," announced Mr. Henderson one
+morning. "We must all get into the small boat and row some distance
+away, as there is no telling what the result of the explosion may be."
+
+"Suppose the submarine is destroyed?" asked Mrs. Johnson.
+
+"Then we will have to sail for the nearest land in the small boat,"
+replied the captain. "I will provision it and we will take all the
+precautions we can."
+
+It was with anxious hearts that the little party embarked in the little
+craft that was carried on the _Porpoise_. It was barely large enough to
+hold them. The professor was the last in, and he lighted a long fuse
+that led to the dynamite before taking his seat. Then with Tom and Bill
+at the oars the little craft moved away.
+
+"How long before the explosion will take place?" asked Jack.
+
+"I timed the fuse for ten minutes," answered Mr. Henderson. "That will
+enable us to get far enough away so we will not be swamped by a wave."
+
+Five minutes later Mark, who was intently watching the volcanic rock,
+gave a loud cry.
+
+"There she goes!" he shouted.
+
+They all looked to behold a wonderful thing. As easily as though it was
+some conjuring trick the rock began to settle down in the water. Lower
+and lower it went until only the tallest jagged points showed above the
+waves, whose crested tops the keel of the ship now almost touched.
+
+"That isn't the explosion!" exclaimed the professor. "The fuse has not
+had time to get to the powder yet."
+
+"But the rock is disappearing!" yelled Andy.
+
+As he spoke the big pile of volcanic stone vanished completely and the
+_Porpoise_ floated easily on the surface of the sea.
+
+"Hurrah!" cried Mark.
+
+"It am de most kloslostrous occurranceness dat eber transpositioned
+itself!" exploded Washington.
+
+"Let's row back to the ship now!" cried Mark.
+
+"Not yet!" said the professor quickly. "The dynamite has not gone off
+yet."
+
+"There it goes now," remarked Jack.
+
+At that instant a big column of water shot upward and a dull rumbling
+could be heard. A few seconds later the little boat rocked violently
+from the effects of the waves. Then the sea became calm, and the
+_Porpoise_ could be seen dancing up and down on the heaving billows.
+
+"Now we can go back in safety," spoke Mr. Henderson, and Tom and Bill
+bent to the oars.
+
+"What happened?" asked Mrs. Johnson. "The rock seemed to disappear
+before the explosion occurred."
+
+"That's exactly what it was," explained the inventor. "By some strange
+freak of nature the volcanic mass dropped back into the ocean a little
+before I was ready to blow it to pieces. In settling down it lowered the
+ship. Then the explosion occurred beneath the waves. If I had waited a
+little while I need not have risked the dynamite."
+
+"Well, there was no guarantee that the rock would go back where it came
+from," remarked Jack.
+
+"No, we had to act," agreed the professor. "But now let us go aboard."
+
+They rowed back to the _Porpoise_, which they found had sustained no
+damage from the queer experience it had been through.
+
+The motors were set in motion and in a little while the craft was again
+moving through the water out of the dangerous vicinity of the volcanic
+area.
+
+"Who has the two watches to-night?" asked Mr. Henderson after supper had
+been served.
+
+"Washington and Andy," answered Jack, who kept track of the matter.
+
+"I guess we'll change it, and have you and Mark take them," went on the
+captain. He gave Jack a peculiar look, and made a sign to him not to say
+anything. Wondering what was to come Jack went up on deck to watch the
+sunset.
+
+
+
+
+CHAPTER XXI
+
+CAUGHT IN A WHIRLPOOL
+
+
+The boy was joined a little later by the captain, who, coming close to
+him whispered:
+
+"I am going to try to discover the ghost to-night. That is why I wanted
+you boys on hand to help me. This thing must be stopped if it is a joke,
+and, if it isn't--"
+
+"Do you think it is some one playing tricks?" asked Jack.
+
+"I don't know what to think," answered Mr. Henderson. "We will see what
+happens to-night."
+
+Mark came on deck a little while, and the three talked of the strange
+appearances of the mysterious white object. The boys told of their
+experiences, and Jack related more fully his on the night the ship went
+up on the big rock upheaval.
+
+"I don't believe in ghosts," said Mr. Henderson, "I'm going to lay this
+one," and he smiled grimly.
+
+Night settled down. Jack, who had the first tour under the new
+arrangement, had made himself comfortable in the conning tower, and Mr.
+Henderson had hidden himself in the companionway. His idea was to thus
+guard both openings into the ship and ascertain whether the ghost came
+from within or without the craft.
+
+Up to a short time before twelve o'clock nothing out of the ordinary
+happened. The only sound was the lapping of the waves on the steel sides
+of the _Porpoise_, and now and then a splash as a big fish leaped out of
+the water. There was only the slightest breeze.
+
+Jack who, somehow or other, felt much sleepier than usual, caught
+himself nodding several times. Once he awoke with a start and realized
+that he had been dozing.
+
+"Come, come," he remarked to himself, "this will not do at all. This is
+a fine way to watch for a ghost."
+
+He remained wide awake for perhaps five minutes. Then he was off to the
+land of nod again. He was just dreaming that he was skating on a pond
+and was playing snap the whip with a lot of boys, when he awoke with a
+start.
+
+He felt something pressing on his chest and to his horror, as he looked
+up, he saw a big towering white object standing over him. A second
+glance showed him it was a man, or the semblance of one, and the thing's
+foot was on his chest.
+
+With a terrified scream Jack sprang up, upsetting the ghost, which, the
+boy thought at the time, seemed rather heavy for an unearthly spirit.
+
+"Did you catch it?" cried the professor.
+
+"No! Yes! I don't know!" yelled Jack, struggling to his feet in time to
+see the white object glide down the stairs that led from the conning
+tower into the forward cabin.
+
+"Run after it! We must solve the mystery!" cried Mr. Henderson springing
+from the companionway up on deck.
+
+But at that moment the ship began to whirl about in a circle slowly at
+first, but with increasing speed until Jack and the professor felt sick
+and dizzy. All about the water seemed to be bubbling and boiling, while,
+at the same time, there arose on the air a mournful howl.
+
+The professor jumped to the rail and looked over the side. What he saw
+made him recoil with horror.
+
+"Quick! Close the man-hole hatch!" he cried. "Shut the door of the
+conning tower!"
+
+"What is it?" Jack managed to ask.
+
+"We are caught in a whirlpool!" Mr. Henderson yelled as he leaped down
+the companionway and pulled the heavy steel cover after him.
+
+Stricken with a nameless dread, Jack closed the water-tight door of the
+conning tower and made his way to the cabin. He could hardly get down
+the stairs, so swiftly was the ship whirling about.
+
+He found the captain busy in the engine room and, in response to calls,
+Washington and Mark came hurrying in. They had been awakened by the
+commotion and the strange movements of the _Porpoise_.
+
+"Turn on all the lights," ordered the inventor. "We must prepare for the
+worst."
+
+The incandescents were soon glowing and in the glare the frightened
+adventurers gathered about Mr. Henderson, wondering what new terror had
+befallen them.
+
+"See!" exclaimed the inventor. "We are going comparatively slow now, but
+we are on the outer edge. Wait until we reach the centre."
+
+He pointed to a compass and, as the needle pointed steadily to the north
+the card seemed to be going around like the hands of a clock that has
+lost the balance and escapement wheels. The ship made three complete
+circles a minute.
+
+Pale and frightened, Mrs. Johnson came from her cabin, whence the
+terrified cries of Nellie could be heard.
+
+"Are we sinking?" she asked.
+
+"Sinking will never harm the _Porpoise_," replied Mr. Henderson. "This
+is something decidedly worse."
+
+"I know! It is a whirlpool!" exclaimed the lady.
+
+"I'm dizzy; I'm so dizzy!" wailed Nellie. "Please stop the ship from
+going round, Mr. Henderson."
+
+She came from her bed crying, and all her mother could do did not quiet
+her.
+
+Meanwhile the submarine continued to whirl about faster and faster in
+the swirling waters. Five times each minute now it made the circuit,
+and, like the coils of a boa constrictor that is enfolding its victim,
+the circles continually grew smaller.
+
+"We are being sucked down," said Jack in a low tone as he glanced at the
+depth gage, and noted that it showed them to be thirty feet under water.
+
+"That is so," remarked Mr. Henderson quietly.
+
+"What will be the result?" asked Mrs. Johnson.
+
+"I do not know," was the answer, and the captain turned aside. He seemed
+to have lost all courage in the face of the new disaster.
+
+"Can't we empty the tanks and rise to the surface?" asked Andy.
+
+"The tanks are not filled," replied Mr. Henderson. "What is taking us
+down is the force of the whirlpool and not the weight of water."
+
+"Then you fear for the worst?" asked Andy.
+
+"I do," said the captain simply.
+
+"Don't give up the ship!" exclaimed the old hunter suddenly. "Never say
+die! It's a long lane that has no turns! Hip! Hip! Hurrah!"
+
+They all turned to stare at the old man.
+
+"Never mind," said Mr. Henderson in a soothing tone, that one would use
+toward a baby, or a person not right in their head. "Never mind. We may
+be saved."
+
+"Oh I'm not crazy!" exclaimed Andy. He tried to caper about but the
+motion of the ship made him dizzy and he had to sit down. "I'm all
+right! I just happened to think of something!"
+
+"What is it?" asked the captain eagerly.
+
+"Send the ship ahead!" exclaimed Andy. "Speed her as fast as she will
+go. Try her strength against the force of the whirlpool! We may win!"
+
+"Good!" exclaimed Mr. Henderson. "I was too much depressed to think of
+that! The ship has powerful engines. Queer you should remember that
+instead of me. Come, Washington, start the screw going! We will try to
+beat the whirlpool!"
+
+The submarine was now whirling around so rapidly that it was difficult
+for any one to stand without leaning against the sides or holding on to
+something. It was going lower and lower down, as the gage showed.
+
+Soon a throb that was felt through the length of the craft told that the
+engine had started. The vibration increased until it seemed that the
+ship would be torn apart. Never had the big screw revolved at greater
+speed.
+
+For a while the struggle between the force of man represented by the
+engine, and the power of nature, embodied in the whirlpool, seemed
+equal. Neither could gain the mastery. The ship continued to slide
+around in ever narrowing circles while the big cable of water, forced
+through the tunnel by the screw, was like a cataract.
+
+"Which will win?" asked the professor softly to himself.
+
+He crawled to the gages and watched them. Only by their needles could it
+be told when the battle had turned in favor of the adventurers.
+
+The circular motion, that was now terrible in its speed and power,
+seemed to culminate in a rush that almost overturned the ship. In the
+engine room Washington was laboring to keep the machine at top speed. He
+put on the last ounce of power.
+
+"Hurrah!" yelled the professor suddenly. "I think we shall win!"
+
+He pointed to the depth gage. The needle, which had showed a constantly
+increasing record, until it was now at two hundred feet, had stopped. It
+showed they were going no lower.
+
+Then Mr. Henderson looked at the indicator which showed the progress
+straight ahead. The needle was beginning to tremble. As he watched he
+saw it move, slowly at first, until, as the powerful screw won a victory
+over the terrible whirlpool. The gage marked one, two and then three
+miles an hour.
+
+"We are leaving the swirling waters!" cried Mr. Henderson.
+
+Then, all at once, as though it was an arrow shot from a gigantic bow,
+the _Porpoise_ cleft the under-billows and shot ahead, free at last from
+the grip of the whirlpool.
+
+Man had triumphed over nature!
+
+On rushed the ship like a race horse, for the engine was working as it
+never had before, and it did not have the pool to contend against.
+
+"Slow down," said Mr. Henderson, "and we will go to the surface."
+
+Two minutes later, under the buoyancy of her empty tanks, the _Porpoise_
+lay floating on the top of the waves, under the shining stars.
+
+
+
+
+CHAPTER XXII
+
+UNDER FIRE
+
+
+"I shouldn't want to go through that experience again," remarked Mr.
+Henderson, as he, with all of the ship's company except Mrs. Johnson and
+Nellie went on deck. "I thought we were lost, sure."
+
+"Lucky our engine didn't go disproportionatin' herself at de mostess
+criticless moment," put in Washington. "Golly, but she suttinly did
+hum!"
+
+"And you deserve credit for making her do the humming," went on the
+professor with a smile.
+
+"Well, we didn't catch the ghost," remarked Jack, "though I certainly
+saw him, it or her, whatever the thing is. I felt it too."
+
+"It's rather strange," spoke the professor. "Every time, or nearly every
+time the ghost, as I suppose we must call it for the present, makes its
+appearance, something terrible happens to the ship. I hope it doesn't
+show up too often."
+
+It was three o'clock in the morning, and they had battled with the
+whirlpool over two hours. They talked of little else, and each one told
+how he or she felt.
+
+"It was just like twisting yourself up tight in the swing, and then
+letting the rope unwind," said Nellie, and they all agreed that she had
+described the sensation perfectly. They laughed, also, a thing they had
+felt little like doing a short time previous.
+
+The engine had run so hard, and some of the bearings had become so warm,
+that for the rest of the night the professor decided to let the
+machinery remain stationary. This would give it time to cool down he
+said, and they could make up the time lost the next day.
+
+Tired out with the night's worry and labors they all slept late the next
+morning, and it was nearly ten o'clock before breakfast was over. The
+ship was started on her course once more, and Jack, who was steering,
+made the engine hum as the submarine scudded along, submerged about
+fifty feet.
+
+"When you have time I would like to talk to you," said Mrs. Johnson to
+Captain Henderson.
+
+"I'm at your service now," replied the inventor.
+
+"What are you going to do with Nellie and me?" the lady went on.
+
+"Take you to the south pole with us," was the answer, with a smile.
+
+"It's very kind of you, and I don't want to put you to any trouble,"
+went on Mrs. Johnson. "But I would like to go back north."
+
+"I'd like to oblige you," returned the inventor, "but I hate to turn
+back now. We are well on our voyage, and I may never get another chance
+to locate the pole. Don't you want to accompany us? Think of the
+glorious achievement!"
+
+"I'd rather go back north," persisted the lady. "But I wouldn't ask you
+to turn the ship around. What I was going to suggest was to sail along
+on the surface for a few days and see if you cannot sight a homeward
+bound steamer or sailing vessel. Then you could put me and Nellie aboard
+her."
+
+"Of course!" exclaimed Mr. Henderson. "I never thought of that. Though
+we will be sorry to lose your company, and that of your little girl, I
+will do anything to oblige you. We will at once go to the surface."
+
+He called the necessary order to Jack through a speaking tube which led
+to the conning tower. In a few minutes the ship shot upward, and emerged
+from the ocean in a little shower of foam and spray.
+
+She lay undulating on the surface, and was just beginning to move
+forward again, under the influence of the screw, when a dull boom echoed
+off to the left.
+
+Jack looked from the observation windows in the conning tower and saw,
+about a mile away a big steamer. From her side a white cloud of smoke
+floated, and then the water splashed about fifty feet from the blunt
+nose of the submarine.
+
+Once more came the boom, the white cloud of smoke and this time the
+water splashed only twenty-five feet away from the bow of the
+_Porpoise_. A third time came the sound, and the splash was even nearer.
+
+"They're firing on us!" yelled Jack.
+
+At his cry the professor ran on deck. He was just in time to see the
+fourth shot made, and this time the shell dropped into the water just
+astern of the _Porpoise_ and so close that when it exploded it sent a
+shower of spray all over the deck.
+
+"Here! Stop that!" yelled Mr. Henderson, shaking his fist in the
+direction of the steamer. "You nearly hit us that time. Do your
+practicing in some other direction!"
+
+"I don't think they can hear you," said Jack. "And besides, I don't
+believe they are practicing."
+
+"Then what in the world are they doing?"
+
+"Shooting at us I guess."
+
+"Why do they want to shoot at us? We haven't done them any damage."
+
+"Perhaps they think we are a torpedo boat," suggested Jack. "Maybe that
+vessel's nation is at war with some other one and wants to sink us if
+it can."
+
+"I believe you're right!" exclaimed Mr. Henderson. "But this will never
+do. They must stop!"
+
+Once more the big gun on the ship was fired and the shell came
+dangerously close. At the same time several other reports, less in
+volume were heard, and the water all about the submarine began to bubble
+as the missiles from the machine guns cut the waves.
+
+"Maybe it's an English vessel sent to capture Mark and me because of
+that anarchist trouble at the hotel," Jack went on.
+
+"Nonsense!" exclaimed the captain. "But whatever it is, we must stop it,
+or they will sink my ship. Wave your handkerchief, Jack."
+
+The boy sprang to the top of the conning tower, in order to permit those
+on the vessel to see him more plainly, and vigorously shook the white
+rag. That it was observed was evident when some one on the steamer
+wig-wagged back a reply. In a few minutes a boat was seen to put off
+from the ship, and soon a little launch, in command of a lieutenant in
+uniform, drew up alongside the _Porpoise_.
+
+"Who is captain of this craft?" asked the lieutenant as he came aboard.
+
+"I am," replied Mr. Henderson. "What do you mean by firing on me?"
+
+"I am Lieutenant Muchmore," said the other, saluting. "Captain Wackford,
+of the _Sylph_, in His Britannic Majesty's service, presents his
+compliments, and asks you to pardon the occurrence. You see we took you
+for a derelict and were trying to sink you."
+
+"I thought perhaps war had broken out between some country and the
+United States since we left port," went on Mr. Henderson, "and that you
+were trying to make a capture."
+
+"No, it was only that we thought you a waterlogged craft, and a danger
+to navigation," repeated the lieutenant. "But what sort of a ship have
+you?"
+
+"Come below and I'll show you the finest submarine that ever was built,"
+answered the inventor with pardonable pride. "If you don't mind, give
+your launch orders to go back to the ship, and I'll show something that
+will make you open your eyes."
+
+Anxious to see what the strange little craft could do Lieutenant
+Muchmore sent his launch back, and went below with Captain Henderson. He
+was astonished at what he saw, and unlike most Englishmen was willing to
+say so.
+
+Mr. Henderson then went to the conning tower. He directed the man-hole
+cover to be clamped on, and then filled the tanks. The ship sank fifty
+feet below the surface and then shot forward.
+
+Seated in the cabin the lieutenant was observing with wonder showing on
+his face at the accomplishment of sailing along under water. Suddenly
+the lights were shut off, and the shutters moved back from the
+bull's-eye windows. The sea, glowing in the beams of the search light,
+was alive with fish, large and small, beautiful and hideous.
+
+"Wonderful!" exclaimed the Englishman.
+
+The bull's-eyes were closed, the lights switched on, and then, speeding
+the engine almost to the top notch the captain steered the submarine
+straight for the war-ship.
+
+He had carefully noted her direction before starting his own craft, and
+he resolved to do a little manoeuvering that would still further
+astonish the visitor. By careful reading of the different gages Mr.
+Henderson was able to come to the surface right in front of the _Sylph_,
+to the no small astonishment of the men on the deck of the vessel.
+
+Then, just to show what the _Porpoise_ could do, the inventor darted
+around the war-ship in a circle. He sunk below the surface, went under
+the keel of the _Sylph_ and came up on the other side. Then he went the
+whole length of her, under water, starting at the stern and ending at
+the bow, where he brought the submarine to a rest in a smother of foam.
+
+"Great! Wonderful! Surprising!" were some of the adjectives Lieutenant
+Muchmore used as he stepped from the conning tower, with Captain
+Henderson, onto the deck.
+
+At the appearance of the officer and the inventor a group of those on
+the _Sylph_ gave three cheers for the little vessel.
+
+"Is she for sale?" asked Captain Wackford.
+
+"No, thank you," replied Mr. Henderson with a laugh.
+
+"Because if she is I'll give you free passage to England with her, on my
+ship," went on the commander. "My government would give a fortune for a
+boat that can do what yours does."
+
+"It is not for sale," repeated Mr. Henderson, "but I have some one on
+board who would appreciate a free passage to England, or any northern
+port."
+
+"Who is it?" asked Captain Wackford.
+
+"A Mrs. Johnson and her daughter."
+
+
+
+
+CHAPTER XXIII
+
+CAUGHT IN AN ICE FLOE
+
+
+Mr. Henderson soon explained the finding of the lady and the little
+girl, and Captain Wackford readily agreed to give them passage to New
+York, as the _Sylph_ was to call at that port.
+
+So Nellie and her mother were put aboard the warship, after bidding
+farewell to the captain and crew of the submarine. Mr. Henderson and the
+boys promised to write to them as soon as they got back from their
+voyage to the south pole, and, amid a chorus of good-byes the _Porpoise_
+resumed her journey.
+
+For several days the submarine forged to the south, and the weather
+became noticeably cooler. Some of the nights were chilly, and those on
+watch were glad of the heavy coats they had brought along.
+
+One morning, after a week of travel, when no interruptions had occurred
+by reason of accidents, old Andy came up on deck, and sniffing the air,
+said:
+
+"We'll sight ice before night, or I'm a Dutchman."
+
+"What makes you think so?" asked Jack.
+
+"I can smell it," replied the hunter, whereat Jack, and Mark who had
+joined him, laughed.
+
+"That is no joke," put in Professor Henderson, who, coming up the
+companionway heard what was said. "Old sea captains will tell you they
+can smell an iceberg long before they can see it."
+
+"I don't claim to be a sea captain," said Andy, "but I once was on a
+whaling voyage and I learned to sniff ice in the air. I saved the ship
+from collision with a berg once."
+
+"Let me see," began the inventor as the adventurers sat about the supper
+table after the meal was finished, "who have the watches on deck
+to-night?"
+
+"Washington first and Bill second," replied Jack looking at the chart.
+
+"Keep a sharp watch for the icebergs," advised the captain. "If you feel
+a sudden chill in the air, and see something white, stop the engine at
+once and call for me."
+
+When the _Porpoise_ had been put in shape for the night, and the
+company, tired out from their labors over a general "house cleaning"
+which Captain Henderson had insisted on, went to bed, Washington took
+his place in the conning tower.
+
+It was quite cold, but as the temperature for several days past had been
+steadily falling, nothing was thought of it.
+
+"I guess I'll git out my fur-lined sealskin coat," said the colored man
+to himself as he felt the chill night air, that seemed to increase in
+frigidity along about eleven o'clock. He went to the cabin to get his
+overcoat, and, returning on deck prepared to spend the rest of his hour
+of watch in ease and comfort. He stretched out on the bench in the
+conning tower, noted that the machinery was working right and that the
+proper course was being steered, and then he let his thoughts drift to
+the many adventures he and his employer had gone through of late, and
+also while on the trip "Through the Air to the North Pole."
+
+Washington gave one frightened, startled look, in a few minutes, so
+comfortable had he fixed himself, but happening to look forward through
+the glass-covered porthole of the tower, he saw something that made the
+cold chills run down his back.
+
+There, right in front of the _Porpoise_, and not a cable-length away was
+a tall, mysterious, white thing which was shimmering in the pale light
+of the moon that had lately risen.
+
+Washington gave one frightened, startled look, and then, with a tongue
+that could hardly move, he yelled out:
+
+"De ghost! De ghost! He'll git me suah!"
+
+Then the colored man made a dive for the stairway leading to the cabin,
+but missed it and brought up with a crash on the steel floor of the
+conning tower.
+
+"What is it?" called Professor Henderson, springing out of his bunk.
+
+"De ghost!" wailed Washington from the huddled up heap he was in.
+
+"Catch him!" yelled the captain.
+
+"I dasn't," moaned Washington.
+
+The next instant the ship quivered from stem to stern. There was a
+terrible shock, followed by a grinding, crashing sound. Then the craft
+seemed to be pressed down by some great weight. It heeled over to one
+side, and the water began to pour down the open man-hole.
+
+"Quick! Clamp on the covers!" shouted Mr. Henderson as he felt the sea
+dashing into the interior of the boat.
+
+Jack and Mark sprang to obey. It took all their strength, for the water
+was running in like a mill-race.
+
+"What has happened?" asked Andy, as he tried to climb up the
+companionway ladder, that was tilted backward.
+
+"I guess we've hit your iceberg!" cried Mr. Henderson.
+
+"I knew I smelled the frozen stuff," replied the old hunter.
+
+They got the covers on the manhole only just in time and they all
+crowded into the cabin, while Jack switched on the electric lights.
+
+"Is the ship damaged?" asked Mark.
+
+"I think not," replied Mr. Henderson. "But we are sinking. Look at the
+depth gage."
+
+The hand on the clock-face was moving slowly around. From ten it went to
+twenty feet, then to thirty and kept going until it stood at seventy.
+
+"Look to the air tanks," ordered Mr. Henderson to Washington, who, by
+this time had recovered from his fright. "See if they are all right."
+
+The colored man came back in a few minutes and reported that the supply
+of compressed atmosphere was safe and that there was plenty of it.
+
+"That's good," remarked Mr. Henderson. "Whatever else happens we can
+breathe for a while."
+
+"But what has happened?" asked Andy.
+
+"I think the top part of an iceberg toppled down on us," was the reply.
+"You know about nine-tenths of a berg is under water. Sometimes there is
+a warm current of the ocean underneath the ice, and it melts. Then it
+becomes top-heavy and tilts over. One of that sort must have caught us,
+and has shoved us down into the sea."
+
+"But why don't we rise again when the ice floe slips off us?" asked
+Mark.
+
+"Because, in all probability the ice will not slip off us," answered the
+professor grimly. "It may be so large that it has caught us like a bug
+under a barn door."
+
+"Then we are fast in the ice under water," spoke Andy after a pause.
+
+"It looks like it," came from the inventor. "However we will not give up
+yet. We may be able to make our way out. Start the engine at full speed,
+Washington."
+
+The machinery which the professor had shut down at the first cry of
+alarm was set going. Soon the throb and hum told that the big screw was
+revolving.
+
+Meanwhile the _Porpoise_ had regained an even keel, and had stopped
+sinking, remaining at the depth of seventy feet below the surface.
+
+"We will first try to go straight ahead," said the captain.
+
+He turned on more power and they all waited in anxiety. The test would
+tell whether they could escape in that direction or not.
+
+But, though the powerful screw churned the water to foam in the tunnel,
+the _Porpoise_ never budged. It was as if she was held in a vice.
+
+"It's of no use," remarked Mr. Henderson with a shake of his head as he
+watched the speed gage and noted that it remained stationary. "We must
+now try the other way."
+
+Once more the big screw was set going, this time in the opposite
+direction, so as to pull the ship out of the ice if it was possible. But
+this, too, was of no avail.
+
+"It looks as if the ice had us," said Andy, trying to speak in a
+cheerful tone. "But there's one way more to try."
+
+"What is that?" asked Mr. Henderson.
+
+"If we were in the air ship we could go up," replied the old hunter.
+"But, as it is, we had better go down. Why don't you fill all the water
+tanks, and try to sink beneath the iceberg? It can't go down so very far
+into the water, and I reckon we could slip under it."
+
+"The very thing!" exclaimed the professor, whose mind was too sorely
+troubled over the happening to enable him to think of plans of escape.
+"That's the best thing to do."
+
+Under the inventor's direction Washington filled the tanks and then, ere
+the pumps had ceased working, the screw was started and the deflecting
+rudder inclined to cause the ship to dive.
+
+One, two, three minutes passed, and still the _Porpoise_ did not move
+toward the bottom of the sea. She remained submerged and stationary.
+Anxious eyes gazed at the dials. The indicating hands trembled under the
+throbbing of the engines, but did not move.
+
+"It will not work!" exclaimed Mr. Henderson in sorrowful tones.
+
+"What does it mean?" asked Bill, who had come up to where the others
+stood.
+
+"It means that we are prisoners in the ice; caught between the upper and
+lower parts of a gigantic berg, and held here under the water."
+
+"Can't we ever get out?" asked Jack, a tremor coming into his voice.
+"Can't we escape when the ice melts?"
+
+"The ice of the southern polar sea seldom melts in this latitude,"
+replied the professor.
+
+An ominous silence followed his words.
+
+
+
+
+CHAPTER XXIV
+
+THE SHIP GRAVEYARD
+
+
+Truly the adventurers were in a position that might well cause the
+stoutest heart to quail. With hundreds of tons of ice above, below, and
+on every side of them, their chances of escaping alive from this frozen
+tomb were very small.
+
+"Can't we make an attempt to get out of this prison?" asked Jack.
+
+"Indeed we will," said the professor. "We will try all the means at our
+command. If they all fail--"
+
+He dared not finish the sentence, but they all knew what he meant. It
+was now about one o'clock in the morning. The ship had become stationary
+after the uneasy motion caused by the oscillation of the big berg.
+
+"We may as well turn in and get a little sleep," remarked Mr. Henderson.
+"We can all work better if we get some rest."
+
+It is doubtful whether any of them slept, for the horror of their
+position was too fresh in their minds. Still, lying down in the bunks
+rested them.
+
+It was six o'clock when Washington awoke. In spite of the dangers of the
+icy grave, he had managed to get a little sleep. He prepared breakfast
+and called the others.
+
+"Make a good meal," advised Mr. Henderson. "We have plenty of work ahead
+of us."
+
+"Are you going to free the ship?" asked Mark.
+
+"I am going to try," was the answer.
+
+A little later the inventor was busy in one of the small store rooms aft
+when Jack came up. The professor was carefully taking out a box
+labelled:
+
+ DYNAMITE! DANGEROUS!
+
+"What are you going to do?" asked the boy.
+
+"I am going to try the same experiment we attempted on the volcanic
+island," was the reply. "Only, this time, I am afraid we shall have to
+complete it to the end. There is little likelihood of the ice falling
+apart."
+
+"Then you are going to blow it up?" went on Jack.
+
+"That's what I hope to do," the inventor went on. "I see no other way,
+and, though there is a risk, it is not so great a one as to wait to be
+crushed in the ice as it freezes more solidly."
+
+Under the directions of Mr. Henderson they got out the diving suits. The
+professor, the two boys and Andy put them on. The dynamite, in
+specially prepared water-proof packages, with long fuses was laid in
+readiness close to the door of the diving chamber.
+
+Into the cell, the four who were to make the perilous journey under the
+ice, took their places. The water was slowly admitted, and then, with
+the electric lights in their helmets throwing out powerful gleams, they
+started forward as the outer door swung open.
+
+It was well they had all taken the precautions to don thick
+undergarments and clothing, for, even through the heavy rubber diving
+suits, the terrible cold of the southern polar sea struck a chill to
+their very bones.
+
+As the professor had said, the ship was caught between the upper and
+lower parts of the iceberg. On either side, ahead and to the rear there
+was open water. Beneath their feet there was a floor of ice. It was as
+if they and the ship had been placed between two great sheets of the
+frozen matter.
+
+Their progress was slow, for the water hampered their movements and each
+one had some of the dynamite to carry. The footing, too, was insecure,
+for the icy bed of the ocean was slippery.
+
+As they were huddled together, the professor in the lead, and their
+lamps making a faint illumination in the darkness, they suddenly became
+aware of a great shadow over them. They looked up, and their hearts
+nearly ceased beating as they saw a gigantic sperm whale right over
+them, and between the ice. The terrible animal had observed them also,
+and, food being scarce in those frigid regions, had evidently made up
+its mind to dine on some choice morsels.
+
+The whale was nearly as large again as the submarine, and to the
+frightened voyagers seemed more immense than a house. With slow motions
+of the flukes the animal placed itself right over the boys and men,
+ready to rush at and take them into its terrible maw.
+
+Old Andy, who alone seemed to retain his presence of mind, stepped to
+the front. The professor and the boys wondered what he was going to do.
+Then Andy held up one of the electric guns.
+
+Always thinking of his chosen calling, the old hunter had picked up the
+weapon as he was leaving the _Porpoise_. He waited until the whale was
+within a short distance, so close in fact that the small eyes, out of
+all seeming proportion to the rest of the big body, could be seen. Then
+Andy fired one of the explosive bullets straight into the open mouth
+that was fringed with rows of the springy bone that is a part of a
+whale's eating apparatus.
+
+The shot took effect, and made a vital wound. In its death struggles the
+beast lashed the ocean to foam, and, but for the fact that Andy as soon
+as he fired the shot crouched down, pulling the others toward the floor
+of ice, they might all have been killed.
+
+The whale turned and made a rush in the opposite direction to that of
+the divers. This was a welcome sign to the professor, for he knew the
+animal was seeking open water and this told him it must be somewhere in
+the vicinity.
+
+Their hearts still beating loudly from the closeness of death, the
+adventurers continued their way. On every side were fish, big and
+little, and, though some of the larger ones thrust themselves to the men
+and boys, as if wondering what strange creatures they were, none of them
+offered to attack.
+
+Led by the professor they made a complete circuit of the ship that was
+held fast in the ice. As the inventor had surmised, the _Porpoise_ was
+nipped only above and below. If she could be freed at either of those
+points she could rise to the surface, or sink down under the ice.
+
+After making a careful examination of the position of the craft, Mr.
+Henderson motioned to have the dynamite placed on the ice, in front of,
+and about two hundred feet away from the nose of the ship.
+
+He connected the cartridges with the fuse and wires that were to explode
+them, and then, taking the free end, he started back toward the ship.
+Washington was on the watch for them, and operated the diving chamber.
+Soon the four were back in the _Porpoise_.
+
+"Now to see if our plan will work," said Mr. Henderson. "I am relying on
+the well known downward force of dynamite to blow a hole in the bottom
+part of the ice, so that we can drop below."
+
+"Why not make a hole above so we can rise and escape?" asked Bill.
+
+"Because," replied the professor, "we are now in the region of perpetual
+ice. The ocean above us is one fast floe, or a number of smaller ones,
+so that, in any event our progress would be impossible. But we can sail
+far enough down under water to escape all the ice. That is the purpose
+of the _Porpoise_. That is why I built her. We will now begin on the
+last part of our voyage; that is if we can get free of the fearful grip
+of this sea of ice."
+
+There was little they could do to protect themselves. They would either
+escape or be blown to pieces in case the explosive exerted too great a
+force. They all put on life preservers to guard against the contingency
+of the _Porpoise_ being ripped apart and themselves cast into the water,
+yet they realized that without their ship, they could live but a little
+while in the ice-filled water near the south pole.
+
+The professor saw that everything was in readiness. He hesitated a
+moment and looked at the electric button in his hand, for this time the
+dynamite was to be detonated by a battery. How much might depend on one
+push of the finger!
+
+There was a slight movement to the muscles of the professor's hand. Then
+it seemed as if a thunderbolt had fallen into the midst of the ocean
+about them.
+
+There was a dull rumble, but the confined space and the thick walls of
+the ship shut most of it out. It was followed by a sickening dizzy
+motion to the submarine. She seemed about to roll over and those in her
+grabbed frantically at the sides. The next instant the craft plunged
+down, down, down, into the water which was filled with broken cakes of
+ice, that rattled against the steel sides, like peas in a pan.
+
+Down and down the _Porpoise_ went, for her tanks were full. More and
+more rapidly she continued to sink, until it seemed she would fetch up
+in the deepest cavern of the ocean.
+
+"We's gwine t' Mars Davy Jones's locker, suah!" Washington exclaimed as
+he looked at the depth gages.
+
+[Illustration: THEY WERE IN THE MIDST OF A GRAVEYARD OF WRECKED
+SHIPS.--_Page 200._]
+
+"Has the experiment succeeded?" asked Andy of Mr. Henderson.
+
+"I think so," was the answer. "At any rate we are free from the ice,
+temporarily at least. We are sinking down through the hole the dynamite
+made, just as I hoped we would."
+
+"Where will we end up?" asked Jack.
+
+"No one knows," replied the captain. "But I would say--"
+
+At that instant the ship stopped sinking and brought up with a bump.
+
+"I should say we were at the end of this part of our journey," finished
+the inventor.
+
+He turned off the cabin lights and lighted the search lamps that threw a
+gleam so the water could be looked at from the bull's-eyes windows. The
+sight that met their gaze was an astonishing one.
+
+They were in the midst of a graveyard of wrecked ships, and, on every
+side, scattered over the ocean bed, were the broken hulks that had once
+been stately vessels.
+
+
+
+
+CHAPTER XXV
+
+CAUGHT BY SEA SUCKERS
+
+
+"What sort of a place is this?" asked Andy, as he gazed at the last
+resting spot of the big ships.
+
+"They have probably drifted here with the ocean currents, become caught
+in the ice and have remained here hundreds of years," said Mr.
+Henderson. "Some of the ships are very old, and, by their build must
+have sailed the waters centuries ago."
+
+"Maybe some of them are treasure ships," suggested Jack.
+
+"They might be," admitted the professor.
+
+"Then we'll go aboard and get the gold," spoke Mark.
+
+"I'm afraid you'll be disappointed," went on the inventor. "In the first
+place most treasure ships are looted before they sink. And it would be
+very dangerous for any of us to venture to explore those hulks."
+
+"Why?" asked Jack.
+
+"Because they are rotten, and liable to fall to pieces any minute. If
+you happened to be in one at the time you would be caught in the
+wreckage and eventually drowned even though you had on a diving suit.
+Then, again, the ice here is constantly shifting about, and a sudden
+motion of the under-water floe might carry you hundreds of miles away.
+So we will not try to hunt for any fortunes on the sunken ships."
+
+With this the boys were forced to be content. They stood at the small
+windows looking at the skeletons of ships that lay on every side of the
+_Porpoise_. Some of the craft were big steamers, and others were small
+sailing vessels. A few had jagged holes in the hulls, showing how they
+had been damaged. A few stood upright, with sails all set, as if
+disaster had suddenly come upon them.
+
+"Well, what is the next move?" asked Andy after a pause. "Are we going
+to stay here?"
+
+"We are going to find the South Pole," spoke Mr. Henderson suddenly.
+"That is what I set out to do, and I am going to accomplish it if
+possible. We have had many accidents and a harder time in some respects
+than when we made our trip to the north in the air ship. But I am sure
+we shall succeed. Start the ship to the south, Washington."
+
+"But we may run into an iceberg," objected the old hunter, who was
+inclined to be cautious.
+
+"I think not," answered Mr. Henderson. "I believe we are on a sort of
+level plane between two vast upper and lower fields of ice. We can go
+freely in any direction excepting up or down."
+
+"How is that?" asked Mark. "I don't quite understand."
+
+"Because there is, I believe, a big sheet of ice above us, one, say
+several hundred feet thick. The same thing is below us, between us and
+the real bed of the ocean."
+
+"But suppose we have to go up to renew our air supply?" asked Jack.
+
+"We can't go," replied the inventor.
+
+"Then we will die."
+
+"Not necessarily. We will steam along until we come to a place where
+there is no ice above us."
+
+"But I thought you said there was nothing but ice above us now."
+
+"So there is, but I intend to head due south and there, I believe, we
+will find an open polar sea. If we do my theory will be proved and we
+will have made a great discovery."
+
+"Forward then!" exclaimed Jack. "Let us strike for the open sea."
+
+The _Porpoise_ began to move ahead. She steamed slowly, for Mr.
+Henderson realized that he was in dangerous waters. He took his position
+in the conning tower, and had Jack with him to assist in looking for
+any obstructions that they might unexpectedly meet.
+
+The big searchlight gave a fine illumination, for the ice above and
+below reflected back the beams, and what would otherwise have been a sea
+of darkness was made one of daylight.
+
+The water swarmed with fish, but they were like none that the
+adventurers had ever seen or dreamed of before. There were monsters with
+hideous heads, and eyes so large that they occupied nearly half of the
+ugly bodies.
+
+Then there were serpent-like forms, fish with long slender bodies and
+whip-fashioned tails, with jaws that extended before them for ten feet
+or more. Others there were, great lumbering monsters that crawled along
+on the ice, somewhat as seals do.
+
+After several hours' travel the submarine ran into a school of fish that
+had shapes like those of polar bears, while their heads were like those
+of sharks. The creatures swarmed up to the side of the vessel, and some
+scratched with their claw-like fins on the glass windows of the conning
+tower and the side bull's-eyes.
+
+A meal was prepared by Washington, and all the adventurers brought good
+appetites to the table. On and on rushed the ship, every hour coming
+nearer and nearer to the pole.
+
+Professor Henderson had turned the steering of the craft over to Mark,
+who, with Jack as an assistant was sending her along at a good speed,
+when suddenly the submarine seemed to slacken in her progress.
+
+"What's the matter now I wonder?" asked Mark.
+
+"Maybe the engine bearings got hot, and Washington had to slow up to
+cool them," suggested Jack.
+
+He looked through one of the side windows in the conning tower, a moment
+later, and uttered a cry of fear.
+
+"What is it?" asked Mark.
+
+Jack pointed with a hand that trembled from fright. Staring at them
+through the thick glass of the bull's-eye the boys beheld the most
+hideous sea monster they had yet encountered.
+
+It seemed to be a vast circular mass of flesh, twenty feet in diameter,
+and, in the middle were two openings each three feet across. They were
+like big holes, and, at the farther end of them could be seen two
+unblinking eyes. In the centre was a horrible mouth, armed with a triple
+row of teeth.
+
+Down below there was a short body, at the end of which was a smaller
+disk, armed with a sharp horny point.
+
+"What is it?" asked Jack in a whisper.
+
+"I don't know," replied Mark.
+
+A moment later Mr. Henderson came up the companionway into the tower. He
+caught one glimpse of the monster.
+
+"It is the great sucker of the polar seas!" he exclaimed. "Quick! Speed
+up the engine! If that one, and the mates of it, fasten on to us we will
+have trouble!"
+
+He pressed the signal that connected with the engine room, and told
+Washington to start the engine at its greatest power. The next instant
+the ship throbbed and trembled under the vibrations of the big screw.
+
+"We may escape!" cried the professor.
+
+As he spoke the ship seemed to come to a sudden stop. The engine could
+still be felt moving, and the big screw still churned the water to foam
+in the tunnel, but the craft was stationary.
+
+"We are caught!" exclaimed the professor.
+
+"So we are!"
+
+The windows in the conning tower were darkened. The big sucker had
+thrown itself forward and spread itself over the glass, clasping its
+horrible form half way about the submarine.
+
+"Let's look at the other windows! There may be only one of the
+creatures!" Mr. Henderson exclaimed, as he hurried down the companion
+way and into the main cabin. He threw back the slides covering the
+glass.
+
+The sight that met his eyes caused him to recoil in horror. There,
+pressing their shapes against the steel sides, and over the bull's-eyes
+of the ship were two more of the gigantic suckers!
+
+The ship had now ceased to move, and Washington, in the engine room,
+feeling that something was wrong, had shut off the power. The
+adventurers were caught in a trap more terrible than that of the ice,
+the volcanic mountain, or the Sargasso Sea. It was a trap from which
+they might never escape.
+
+The suckers, thinking the submarine was perhaps a species of fish, like
+themselves, and one of their enemies, had fastened on it their fatal
+vice-like grip. To move through the water, with the weight of all that
+clinging flesh was impossible.
+
+"What sort of creatures are they?" asked Jack, speaking in a whisper, so
+great was the terror inspired by the presence of the gigantic sea
+suckers.
+
+"I never saw any of them before," replied the professor, "but I have
+read about them. They live only in the polar regions and are a species
+of octupus, only more terrible. Their powers of suction are enormous,
+and once they fasten on a fish or animal they never let go until they
+have absorbed it completely. They act in the same way that a star fish
+does on an oyster."
+
+"But they can't eat the ship," said Jack.
+
+"No, I fancy the steel and iron sides will prevent them from making a
+meal of us."
+
+"Then where is the danger?"
+
+"They will not let go until they discover that they cannot devour us,
+and it may take days. We can only remain under water a comparatively
+short time at the most. So you see where the danger is."
+
+"But can't we go out and kill them? Then they would let go."
+
+"It would be most risky to venture out, protected even with a diving
+suit, and carrying the electric guns," the professor went on. "No, I
+must think of some other plan to free ourselves from the creatures."
+
+"Blow 'em up wif dynamite an' send 'em inter disproportionately
+contrastedable circumferences!" exclaimed Washington, who had been
+listening to the conversation.
+
+"This isn't any time to joke," Mr. Henderson said sternly.
+
+"I wasn't joking," replied the colored man. "Can't we squirt acid on 'em
+or chop 'em up, or--or--"
+
+"We can do nothing for the time being," said the professor. "Come, we
+will have a consultation on the subject. Perhaps some one may be able to
+think of a plan of rescue."
+
+"Let us hope so."
+
+They all gathered in the cabin. The professor explained the nature of
+the creatures, as far as he knew them from what he had read or heard. He
+pointed out, through the glass windows, over which the suckers were
+still clinging, how they maintained their grip, by exhausting, through
+their big mouths, the air between their saucer-like surfaces and the
+ship to which they were clinging.
+
+"Can't we go out and fight 'em?" asked Andy, who was always ready to use
+a gun.
+
+"I doubt if we could get out," replied the professor. "Though we can not
+see them, I believe the creatures cover every part of the ship from stem
+to stern. We could never open the door of the diving chamber with that
+terrible sucker covering the iron portal."
+
+"Maybe if we wait long enough a lot of sharks will come along and eat
+'em up," put in Jack.
+
+"I am afraid sharks will not come to these frozen waters," said the
+professor. "They like a warm climate."
+
+"And you don't think it would be feasible to use dynamite," asked Mark.
+
+"We can't get out to place it where it would blow up the fish and not
+us," answered Mr. Henderson. "If we could it might serve."
+
+A silence fell on the group. They were in sore straits and there seemed
+no hope of rescue. The big disk-like bodies that covered the windows did
+not move, but remained there, staring with horrible persistency into the
+interior of the ship.
+
+
+
+
+CHAPTER XXVI
+
+LAND UNDER ICE
+
+
+Suddenly the craft began to move. Slowly at first, then, with more speed
+it forged ahead through the water.
+
+"Are we free?" asked Andy, starting up.
+
+"Who started the machinery?" demanded the professor.
+
+"No one," replied Jack. "We are all here. There is no one in the engine
+room."
+
+"But we are moving," said Mark.
+
+"It's dem sucker-fish!" exclaimed Washington. "Dey is takin' us off to
+der dens an' dere we'll all be eat up!"
+
+"I'm afraid part of it is true," said Mr. Henderson. "The creatures are
+certainly making off with us. How powerful they must be!"
+
+"Will dey take us to a cave?" faltered Washington. "Will dey eat us up?"
+
+"I don't think they'll eat us up," spoke the inventor. "It would defy
+even their powerful sucking apparatus to bore through the steel sides of
+the _Porpoise_. What I am afraid of is that they may move us to some
+hidden depth where we will be caught under the rocks or in the ice, and
+so lose what little chance there is of getting free."
+
+"And the worst of it is we can't do a thing to help ourselves!"
+exclaimed Andy. "This is the worst game I was ever up against!"
+
+The adventurers were indeed helpless. They could not get out of their
+ship to attack the monsters, even had they dared to. Their engine,
+powerful as it was, had proved no match for the creatures, and now they
+were being carried away, ship and all, to some unknown place.
+
+The ship did not go through the water fast. Though the suckers seemed to
+be working in union their bodies were too unwieldly, and the ship so
+large, that their pace was slow. Nevertheless they kept steadily on.
+
+Several times, in their desperation, the adventurers tried the force of
+the big screw against that of the suckers. It was of no avail. Neither
+was the device of emptying the tanks, and trying to force the craft up
+as far as the roof of ice would permit it to go.
+
+"It's of no use," announced Mr. Henderson with something that sounded
+like a groan. "We must prepare for the worst."
+
+"How long can we live here without going to the surface after a fresh
+supply of air?" asked Bill.
+
+"About three days," was the answer. "I took the precaution to put a
+double supply into the tanks, in readiness for an emergency, but I never
+thought of such a terrible situation as this."
+
+The submarine seemed to be moving more rapidly now. It was useless to
+try to see through either the windows in the side or in the conning
+tower, for all the glass was covered by the horrible bodies.
+
+"What will they do with us when they get us where they want us?" asked
+Andy.
+
+"What can they do except hold us prisoners until--until--" The professor
+broke off the sentence he dared not finish.
+
+For an hour or more the craft was moved through the water at moderate
+speed. Then it came to a stop. Those on board were alert for what might
+happen next.
+
+"I guess dey done got us in der cave," said Washington with chattering
+teeth. "Now dey'll begin to devour us wid dem terrible big mouths!
+Golly, I wish I was home!"
+
+"Stop that nonsense!" exclaimed Mr. Henderson. "Be a man! There is no
+danger yet. The sides of the _Porpoise_ will defy worse enemies than
+those attacking us!"
+
+At that instant the ship began to move again. It was hauled slowly
+through the water.
+
+"They are pulling us backward!" said Andy, as he watched the needle of
+the compass.
+
+Once more the submarine was stopped. Then it moved forward at a more
+rapid pace than at any time since the suckers had seized it. An instant
+later it brought up against some solid object with such a jar that those
+inside were thrown off their feet.
+
+"Something has hit us!" cried Jack.
+
+"More likely we've struck something," said the professor.
+
+Again the ship forged to the rear, and once again it was sent swiftly
+ahead. Then came the second shock, harder than the first, which sent
+some of the party headlong.
+
+"They are banging us against a rock!" cried Mr. Henderson.
+
+"Do you mean those sea suckers?"
+
+"Yes. They have probably found that the shell of the _Porpoise_ is too
+hard even for their powerful jaws. So they have taken us to some place
+where the rocks show and are banging us against them in order to break
+the ship, so they can get at what is inside."
+
+Once more the ship was drawn backward and again dashed against the
+stone. The shock was a hard one and toppled over all who were not
+clinging to something.
+
+"They are ramming us bow on against the rocks," cried Andy. "It will
+break us apart if they hit us many more times!"
+
+Washington hurried forward. He came back with his eyes showing terror.
+
+"There's a lot of rocks right ahead ob us!" he exclaimed. "I see 'em
+through th' little window jest above th' screw. There's land under this
+here water!"
+
+"Land under this ice do you mean?" asked the professor.
+
+"That's what I mean, an' we's bein' rammed agin th' rocks!"
+
+"There it goes again!" cried Jack, as the ship shivered from stem to
+stern against the impact of the blow.
+
+"This can not last long," said Mr. Henderson. "If they strike us many
+more times some of the places will start, the water will come in, and we
+will drown!"
+
+"But what can we do?" asked Jack.
+
+"Let's go out now and see if we can't kill some of the beasts with the
+guns," suggested Andy.
+
+"I cannot permit it," answered the inventor. "Our position is bad enough
+as it is, but to go out would be to lose our lives for a certainty. The
+suckers would swallow us up in a moment. I must find some other way."
+
+There was a period of silence, while all waited anxiously for what was
+to happen next. It was not long in coming. The next impact of the ship
+against the rocks was the hardest yet, and it seemed that more of the
+suckers must have gripped the craft.
+
+"She's leakin' a little!" exclaimed Washington coming back from an
+inspection forward. "De water am tricklin' in!"
+
+"We must fight them!" exclaimed Andy. He ran to get a gun and his diving
+suit.
+
+"Don't try to go out!" warned the professor. "You will surely be
+killed."
+
+"I'd rather be killed out there than die shut up in the ship!" cried the
+old hunter. "I'm going out!"
+
+"Wait!" exclaimed Jack suddenly. "I have a plan that may save us!"
+
+"What is it? Speak quickly!" said Mr. Henderson. "We are in desperate
+straits!"
+
+As he spoke there came another crash against the rocks.
+
+"We must electrocute the suckers!" cried the boy.
+
+"Electrocute them? What do you mean?"
+
+"Take the wires from the electric light circuit, attach one to each end
+of the ship, and start the dynamo at full speed!" answered Jack.
+
+"What good will that do?"
+
+"The ship is steel," went on the boy. "It will become charged with a
+powerful current. We can insulate ourselves by putting on rubber boots,
+but the shock of the electricity will kill the creatures!"
+
+"Good for you!" exclaimed Mr. Henderson. "Quick boys, everybody lend a
+hand! Washington, detach the wires and run one to the bow and the other
+to the stern of the ship. Then get out the boots."
+
+In a few minutes the dynamo was ready to send a death-dealing current
+through the entire ship. The professor and all the others put on the
+boots, that were a part of the diving equipment. The dynamo was started
+at full speed and the purring hum told that electricity of great power
+was being developed.
+
+The professor stood with his hand on a switch, ready to close the
+circuit as soon as sufficient power had accumulated. Once more the
+suckers backed the ship in order to give it impetus for another impact
+on the stones.
+
+Click! The professor snapped the switch shut. There was a burst of
+bluish-green flame, and the movement of the boat suddenly ceased.
+
+"I guess that does for 'em!" shouted Andy.
+
+"Wait a few minutes," advised the professor. "The suckers may not all be
+dead yet!"
+
+He kept the current flowing throughout the length of the ship for
+several minutes, and then turned it off.
+
+"Now to see if the plan worked," he said. The windows in the cabin were
+eagerly scanned.
+
+"Hurrah!" cried Mark. "The suckers have gone!"
+
+"I guess the electricity killed them," spoke Mr. Henderson. "We will
+venture out now in our diving suits and see what sort of a place we are
+in."
+
+Soon the adventurers were arrayed in the heavy suits. Under them they
+wore thick clothing, and in each suit was placed a small flat heater,
+operated by a storage battery. The heaters were made of coils of fine
+wires, and the electric current, meeting with much resistance in passing
+through them, heated the coils, so there was considerable warmth.
+
+It was all needed as they found when they felt the water entering the
+diving chamber, for the fluid was as cold as an ocean full of icebergs
+could make it. Protected however by the heavy suits, warm clothing and
+the heaters the divers were fairly comfortable.
+
+The outer door was opened and they all started back in amazement at the
+sight which met their eyes. Before them lay a forest of real trees, with
+bushes growing among them, while the ground, instead of being like the
+usual ocean bed was covered with grass.
+
+As Washington had said, on getting a small view of the place from the
+little window, it was real land under water.
+
+Their first surprise at the strange spectacle over, the adventurers
+glanced about for a sight of the terrible sea suckers. But they need not
+have feared. Lying in a huddled up mass toward the rear of the
+_Porpoise_ were the dead bodies of the ugly creatures. The electricity
+had finished them.
+
+
+
+
+CHAPTER XXVII
+
+ATTACKED BY AN OCTUPUS
+
+
+They walked some distance away from the ship, for the land under the
+water was easy to travel on. It looked exactly as if some beautiful
+valley had suddenly been submerged in the middle of summer, when
+everything was fresh and green.
+
+They had gone perhaps a quarter of a mile from the _Porpoise_ when
+Professor Henderson motioned to them that they had better return. On
+their way back they passed what looked to be a large cave in the side of
+a hill. Wondering what could be in it, Mark and Jack paused to peer into
+the black opening.
+
+The next instant two long white things, like slender serpents shot out.
+With the rapidity of lightning they wrapped themselves, one about each
+boy, and, before the horrified companions of the lads could do anything
+the unfortunate youths were whisked out of sight into the cavern.
+
+For a few seconds no one knew what to do. To rush in to the rescue of
+the boys would have been foolhardy, as the terrible octupus, which they
+knew had grabbed the lads, would have been a match for all of the
+adventurers, unarmed as they were.
+
+It would be necessary to return to the ship and come back with some of
+the electric guns, which they had neglected to bring with them. In the
+meanwhile the beast might, and probably would, kill Mark and Jack. But
+there was nothing else to do.
+
+The professor motioned for Andy to remain on the watch at the mouth of
+the cavern, so as to be on hand in case he could help the boys, while
+the others were hurrying toward the ship. Then, leading the way, the
+Professor signalled for Tom and Bill to follow him.
+
+They could not hurry much for the heavy suits and the resistance of the
+water impeded their progress. But they made all the speed they could,
+urged on by a terrible fear.
+
+Meanwhile old Andy stood in front of the cave, hoping against hope that
+there might be some way of aiding the boys. If it had happened above
+water he would not have hesitated to rush in and give battle to the
+beast, even though he was unarmed. If he had his knife now he would
+venture in, at the risk of his life.
+
+"Oh, why didn't I bring my gun along!" thought Andy regretfully.
+
+His hand dropped to his side and his fingers came in contact with a big
+knife in the belt of the diving suit. Here was a weapon he had forgotten
+all about.
+
+He drew forth the blade. It seemed a small one with which to attack so
+large and terrible a creature as the octupus. Yet to remain there,
+knowing the boys were being killed was more than old Andy could stand.
+Grasping the handle with a firm grip he started toward the cave. His
+foot caught in something, and he nearly fell.
+
+Looking down to see what had tripped him he saw a long thin pole,
+straight as a lance. It had once been a tree limb, but all the branches
+were stripped off.
+
+"Now if I only had an iron point for that," Andy thought. Then he
+recollected the knife in his hand.
+
+"The very thing," he remarked aloud, the words sounding startlingly loud
+in the confinement of the copper helmet. "If I only had something to
+fasten the knife on the pole I could make a spear to attack the
+octupus."
+
+Then he saw long streamers of sea weed growing up from the ocean bed.
+They were very tough, a kind of wirey grass that was as strong as rope.
+Andy cut several streamers and, with a hunter's skill bound the knife to
+the end of the staff.
+
+Now he had a weapon formidable enough to venture in and give battle to
+the monster. He hesitated no longer, fearing that even the short delay
+might have been too much and that the boys were dead. He entered the
+cave. At first he could perceive nothing for it was quite dark. Then, as
+his eyes became used to the gloom, which the lamp in his helmet faintly
+illuminated, he saw, far back in the rear, the horrible octupus.
+
+Two dark objects, around which were wrapped several folds of the
+terrible arms, Andy guessed to be Mark and Jack, and when he was a faint
+glow coming from them he was sure they were the boys, the gleams coming
+from the lamps in their helmets.
+
+Warily the hunter approached the creature. If he had hoped to take it
+unawares he was disappointed, for, when he had come within ten feet,
+holding his improvised lance outstretched ready for a deadly thrust, the
+creature shot out two long arms toward Andy.
+
+Now the battle began. The snake-like feelers, armed with big saucer
+shaped suckers, lashed about in the water, seeking to clasp the hunter
+in their deadly embrace. But Andy, who had fought many kinds of wild
+animals on land, did not lose his presence of mind in confronting this
+beast of the sea.
+
+Nimbly, in spite of the handicap of the heavy diving suit, Andy dodged
+the arms. Watching his chance he thrust at one, and the sharp knife
+severed the end. But another arm shot out, while the wounded one was
+drawn in, and the battle was as much against the old hunter as before.
+
+Once more he thrust his lance, and this time he severed one of the arms
+close to the ugly body. The creature, in its rage and pain, redoubled
+its efforts to clasp Andy.
+
+The hunter decided to try to get to closer quarters where he could use
+his spear on the body of the beast. He stooped down and wiggled along on
+the bottom of the cave. But the creature saw him, and darted an arm out
+to pull the old man in. Andy squirmed to one side, and then, being as
+close as he desired, he rose to his feet and, drawing back the pole
+thrust it with all his force straight at the centre of the
+whitish-yellow body that was like a horrible lump of soft fat directly
+in front of him.
+
+At the first touch of the knife the creature squirted out an inky
+substance that made the water about it as black as night. Andy could not
+see, but he could feel that the lance was still in the body. He pulled
+it back a little and thrust again and again, turning it around to
+enlarge the wound he had made.
+
+Then, what he had feared all along happened. Two of the creatures arms
+found him, and he felt the terrible pressure as they wound themselves
+about him, the sucker-plates clinging fast. Yet in it all he did not
+lose his presence of mind, nor did he let go of the pole.
+
+Tighter and tighter the arms clasped him. He struggled with all his
+strength but he was in a grip more powerful than that of a boa
+constrictor. Suddenly the pole he was holding snapped off. He let go the
+useless end and pulled the shorter part, to which the knife was bound,
+toward him. Andy felt his senses beginning to leave him, but he
+determined to make one more effort.
+
+One hand was free, that holding the knife. With his last remaining
+strength he cut and slashed at the arms of the creature that were
+clasped about him.
+
+Again and again he stuck the blade into the gristle like substance.
+Could he win? Could he save his own life, to say nothing of that of the
+two boys?
+
+The creature was lashing about now so that the water was a mass of black
+foam. The ink-color was beginning to fade away. Andy could dimly observe
+the horrible front of the octupus, and see the wound his lance had made.
+Then all seemed to grow dark again. He dimly remembered trying to
+thrust the knife into one of the saucer-shaped eyes, and then of a
+sudden his senses left him.
+
+When Andy came to his senses he found himself lying on the ocean bed
+just outside the cave. About him stood the professor, Washington, Tom
+and Bill. His head buzzed and he felt weak, but he knew he was
+uninjured, and that his diving suit had not been punctured in the fight
+with the octupus, for he could feel the fresh air entering from the tank
+at the back of his helmet.
+
+Were the boys killed, Andy wondered. Had his fight to save them been in
+vain? He managed to stand up, and then, to his relief he saw Mark and
+Jack standing behind Tom and Bill. The boys seemed weak but otherwise
+uninjured.
+
+The professor motioned to know if Andy could walk and the old hunter
+soon demonstrated that he could by stepping forward. Then the party
+proceeded slowly to the ship.
+
+Little time was lost by each one in divesting himself of his diving suit
+as soon as they had left the water chamber. The first thing Andy asked
+when his helmet was off, was:
+
+"Did I kill the beast?"
+
+"Indeed you did," replied the professor. "And just in time, too. You
+were about done for when we came back with the guns, but they were not
+needed. My! But you must have had a terrible fight!"
+
+"I did, while it lasted," said the hunter. "But were the boys hurt?"
+
+"They can speak for themselves," replied Mr. Henderson. "I guess not,
+though."
+
+"Having the wind almost squeezed out of us was the worst that happened,"
+said Mark. "The octupus must have recently dined when it grabbed us, for
+it didn't offer to eat us. And it didn't grip us as tightly as it might
+have or I reckon we wouldn't have come out alive. I thought sure we were
+going to be killed, however."
+
+"So did I," put in Jack.
+
+"I don't want any more such fights this trip," said Andy with a weak
+smile.
+
+
+
+
+CHAPTER XXVIII
+
+OUT OF THE ICE
+
+
+Worn out with their encounter with the octupus, Andy and the boys were
+glad to take to their bunks. The others, too, who were weary from
+traveling under water, felt the need of rest, and so it was decided to
+let the ship remain stationary down on the bottom of the ocean for
+several hours before going on further.
+
+"When we get rested up we'll have a good meal, and then try to gain the
+surface of the ocean," said the professor.
+
+There was quiet on board the _Porpoise_ for a long time. Washington was
+the first to awake and he at once set about getting a meal. When it was
+ready he called the professor, and, one after another all the
+adventurers rose from their bunks and refreshed themselves with hot
+coffee, bacon, eggs and preserves, all prepared from condensed foods, of
+which a large supply had been brought.
+
+"Now to see if we can make our way upward through the ice," announced
+Mr. Henderson.
+
+"We ought to be far enough south to strike the open polar sea which I
+believe exists."
+
+The engine was started after the small leaks in the bow, caused by the
+ramming of the boat on the rocks, had been stopped up, and the
+professor, entering the conning tower, turned her due south.
+
+The screw vibrated in the tunnel, the water rushed out in a big stream,
+the engines and dynamos hummed, and the hearts of all were lightened as
+they knew they were nearing the goal of their journey.
+
+Several hours passed and the professor, who was keeping watch of the
+gages noted they had covered more than one hundred miles. As the supply
+of compressed air was getting low Mr. Henderson, not wanting to run any
+chances, decided to make an attempt to reach the surface and refill the
+tanks.
+
+Accordingly the water tanks were emptied of their ballast, the rudder
+was set to force the ship to the surface, and soon the depth gage showed
+a constantly decreasing amount of water over the heads of the
+adventurers.
+
+"Now, if we don't hit the ice above us we'll be all right," spoke Mr.
+Henderson. "We are within fifteen feet of the surface."
+
+Hardly had he ceased speaking when the _Porpoise_ brought up against
+something with a bump that jarred everyone. Then the submarine went
+scraping along, hitting the conning tower every now and then.
+
+"Not clear of the ice yet," said Mr. Henderson. "We must go down a
+little and try again."
+
+The tanks were filled with enough water to keep the boat about fifty
+feet under the surface, and at that depth she was sent ahead at full
+speed. The professor's face wore an anxious look, and when Washington
+asked him if it was not time to replenish the air supply of the boat the
+inventor told the colored man to be very sparing of the contents of the
+compressing tanks.
+
+"I'm afraid we are not as near the open sea as I at first thought," Mr.
+Henderson finished.
+
+On and on rushed the _Porpoise_. The engines were kept at full speed,
+and after two hours of this fast run another attempt was made to reach
+the surface. Once more the thick ice intervened.
+
+"Guess we'll have to blast our way out," observed Andy. "We seem to have
+lots of trouble on this trip."
+
+"Why not try to ram your way through," suggested Jack.
+
+"How do you mean?" asked Mr. Henderson.
+
+"I mean to sink the boat say two hundred feet. Then start her up
+obliquely and perhaps the sharp prow will cut a hole through the ice."
+
+"Hardly through ice fifteen feet or more thick," said the captain
+despondently.
+
+"But it may be thinner now," persisted Jack.
+
+"At any rate it will do no harm to try," the inventor admitted. "We can
+not last much longer down here."
+
+Again the tanks were filled, and by the aid of the deflecting rudder the
+_Porpoise_ went down into the depths. Then the ballast tanks were
+quickly emptied, and the rudder turned so as to force the craft upward
+on a slant. The engine was set going at top speed.
+
+"Hold fast everybody!" called the professor. "It is kill or cure this
+trip!"
+
+Like an arrow from a bow the _Porpoise_ shot upward. On and on it sped,
+gathering momentum with every foot she traveled.
+
+Suddenly there came a terrible crash, a grinding sound and a rending and
+tearing. The ship trembled from end to end. Every one was knocked from
+his feet. There were bumpings and scrapings all along the sides of the
+submarine. Then, with one final spurt of speed, the little ship tore her
+way through the ice and emerged, with a splash and shower of foam into
+the open sea!
+
+Quickly the man hole was opened and, half dead from lack of fresh air,
+the adventurers crawled out on deck. It was night and the stars
+glittered in the sky above. They were just beyond the edge of the ice
+field, and all about them was a wide open sea.
+
+"I was right after all," said the professor, "but I miscalculated the
+distance. Had we gone on a few feet farther it would not have been
+necessary to break through the ice."
+
+"I guess it's a lucky thing we didn't try it before either," remarked
+Andy. "We never could have bored through fifteen feet of the frozen
+stuff. Where we plowed up it is less than two feet," and he pointed to
+where the immense floe came to an end.
+
+It was decided to go no farther that night, however, as the professor
+wanted to take some observations by daylight and ascertain his position.
+So filling their lungs with the air, cold and piercing though it was,
+the adventurers descended to their cabin, and lots were drawn to see who
+would stand the two night watches. It fell to Mr. Henderson to take the
+first, and Washington the second. The captain accordingly took up his
+position in the conning tower and prepared to pass several hours.
+
+He was busy thinking over the exciting times he and his companions had
+passed through, and planning new trips to see more wonders of the world,
+when his attention was attracted by slight noise near the man hole
+leading to the amidship companionway.
+
+The professor looked up, and was startled to see a tall white object,
+with outstretched arms advancing toward him with slow and stealthy
+tread.
+
+"The ghost again!" exclaimed the inventor softly. "I must catch it now,
+and see what foolishness it is," for the professor did not believe in
+spirits.
+
+He got down on his hands and knees the better to escape observation,
+should the white thing prove to be a bodily substance, and started to
+crawl toward it. He came within ten feet of the thing, and could make
+out that it was a man, or at least the semblance of one, all clothed in
+white.
+
+Nearer and nearer the inventor crawled to the thing. It turned to face
+him now and Mr. Henderson could not help feeling startled as he saw the
+object had no head. The neck ended in a white stump.
+
+In spite of a little feeling of qualmishness, which even his boasted
+disbelief in ghosts did not save him from, Mr. Henderson was about to
+spring upon the thing and solve the mystery.
+
+At that instant, however, Washington, who was coming on deck to take up
+his watch, appeared at the head of the companionway, and caught sight of
+the terrible object.
+
+The yells of the colored man as he dove downward and back into the
+cabin, aroused the ship. Determined to solve the mystery, in spite of
+everything, the professor made a leap forward. He slipped, and tumbled
+down the iron stairway. At the same time, the ghost, with a blood
+curdling yell, leaped over the professor's back, and disappeared down
+the stairs of the conning tower.
+
+In an instant the crew were rushing from their bunk rooms, seeking a
+meaning for the disturbance.
+
+"It was the ghost again," explained the professor as he picked himself
+up, not much the worse for his tumble. "I tried to catch it, but I
+didn't. Come, Washington, it is your turn to stand watch."
+
+"Not to-night," said Washington firmly.
+
+It was no use to urge him, so Jack good-naturedly stood Washington's
+trick. Nothing further however occurred that night.
+
+In the morning the professor made several observations and found that he
+was within one hundred and fifty miles of the south pole.
+
+"We'll make it to-morrow, if we have luck," he said.
+
+
+
+
+CHAPTER XXIX
+
+THE BOILING WATER
+
+
+The hours passed and the strange voyage continued.
+
+The _Porpoise_ traveled along at good speed, and the professor devoted
+most of his time to looking after the different scientific instruments
+and gages, for they were nearing the south pole. The deflecting compass,
+which when it came directly over the place corresponding to the pole,
+would point straight up and down, was assuming more and more of a
+perpendicular position.
+
+"We are getting there!" exclaimed the professor with delight. "A few
+hours more and we will have won the goal!"
+
+There was considerable excitement on board when the professor's
+announcement was made. Though few of the adventurers cared as much for
+the scientific achievement as did Mr. Henderson, they were all glad he
+was about to succeed. To most of them the locating of the south pole was
+no different from visiting some new country, excepting that there were
+more adventures than on most voyages.
+
+At dusk the _Porpoise_ went to the surface and during the night traveled
+along atop of the billows. In the morning she dived below again. The
+engine was started at high speed and the deflecting needle dipped still
+more.
+
+"We's gittin' dar!" exclaimed Washington as he oiled the various
+bearings of the machinery.
+
+Breakfast was served and hurriedly eaten, for the excitement was telling
+on every one. After the meal had been cleared away they all sat in the
+darkened cabin looking out at the water as it slipped past the glass
+windows. Big and little fish swam up and peered into the bull's-eyes and
+then darted away.
+
+"That's sort of queer," remarked Jack a little later.
+
+"What is?" asked Mark, who was sitting near his chum.
+
+"All the fish seem to have suddenly disappeared," replied Jack. "There
+were hundreds a little while ago, and now I haven't seen one looking in
+the windows for some time."
+
+"Perhaps there's a big fish on their trail," observed Mark. "That's what
+makes 'em take to the deep sea weed."
+
+"Maybe so," replied Jack.
+
+A little later Professor Henderson entered the room. He went over,
+looked at the thermometer, and then called to Washington:
+
+"Have you got the heat turned on?"
+
+"No, sah! I ain't done truned on no superheated vapor into de
+radiators," replied the colored man. "I were jest thinkin' dat we'd hit
+de south pole by de feel of it."
+
+"It is getting strangely warm," admitted Mr. Henderson.
+
+"Ain't that what you expected at the south pole?" asked Andy. "I thought
+it was hot at the south pole and cold at the north."
+
+"That's what lots of people imagine," said the professor, "but except
+for the open sea, which I have proved does exist, I guess it's just as
+cold at the south as at the north, especially in the winter. We have
+struck the summer season."
+
+"And a mighty warm one at that," observed Jack. "Whew! I've got to take
+off my coat."
+
+Indeed it was getting uncomfortably warm in the ship, and the
+adventurers who had dressed in thick clothing to guard against the
+rigors of the icy climate, soon had to lay aside many of their garments.
+
+"No wonder!" exclaimed Mr. Henderson, as he looked at a thermometer. "It
+is eighty degrees in here!"
+
+"Worse than workin' in a hay field," observed Bill, as he wiped the
+beads of perspiration from his forehead.
+
+"Let us see what sort of water we are traveling through," suggested the
+professor, as he again turned off the lights in the cabin so that a view
+could be had from the bull's-eyes.
+
+Wondering what would meet their gaze the adventurers peered out of the
+small circular windows. At first they could hardly believe their eyes.
+
+There, right before them, the sea was bubbling as if it was an immense
+tea kettle. Steam formed on the glass, and big clouds of vapor could be
+seen. The atmosphere of the cabin became almost unbearable.
+
+"We are in the midst of a boiling hot ocean!" cried the professor.
+
+"Are we sailing through hot water?" asked Andy.
+
+"I should say so, from the feel of it," answered Mr. Henderson. "Put
+your hand on the side of the cabin."
+
+Andy laid his fingers against the steel plates. He drew back.
+
+"I burned myself!" he exclaimed.
+
+"What are we to do?" cried Jack.
+
+"Get out of this by all means!" exclaimed the inventor. "If we stay in
+this hot ocean we will be boiled alive like fishes in a pot. Send the
+ship up, Washington!"
+
+Indeed it was high time. The thermometer marked one hundred and ten
+degrees, and was rising. The interior of the _Porpoise_ was like that of
+a steam laundry three times heated. Stripped to their undergarments the
+adventurers were obliged to lie down on the floor of the cabin where it
+was a little cooler.
+
+It was all Washington could do, used as colored people are to the heat,
+to go into the engine room, and start the machinery that emptied the
+tanks, so as to allow the ship to mount to the surface.
+
+The _Porpoise_ began to rise slowly, and to the suffering men and boys
+it seemed that she never went up so reluctantly. The heat was becoming
+unbearable. They could hear the water bubbling even through the steel
+sides of the submarine.
+
+
+
+
+CHAPTER XXX
+
+CONCLUSION
+
+
+Could they live to reach the surface? was the thought in the mind of
+every one. The heat was terrific. They were breathing in gasps.
+Professor Henderson went to the water tank, thinking to throw some of
+the fluid over himself and his companions, but he found it so warm that
+it almost burned his hand.
+
+"Keep up your courage!" exclaimed the inventor. "We will soon be at the
+top!"
+
+Almost as he spoke the _Porpoise_ bounded from the waves, and fell back
+in a splash of foam on the surface of the billows. They were at the
+surface.
+
+The professor rushed for the manhole and soon opened it. He crawled out
+on the deck, followed by the others. They breathed in deep breaths of
+the fresh air.
+
+The submarine continued to sail on. Every minute the sea seemed to boil
+more violently, until at last the waves were covered with a cloud of
+steam, through which it was difficult to observe where they were going.
+
+"Hadn't we better turn back," suggested Mark.
+
+"Our only hope is to press on," replied Mr. Henderson. "We may cross
+this zone of boiling water soon."
+
+He went into the conning tower to make an observation. He came on the
+deck the next minute, very much excited.
+
+"What's the matter? Are we sinking?" asked Andy.
+
+"We are directly over the south pole!" exclaimed the professor. "We have
+reached the goal! We have come to the spot hundreds of men have tried to
+reach! It has been left for us to succeed. Look at the deflecting
+needle!"
+
+They crowded into the conning tower to note it. The slender hand of
+steel stood straight up and down, indicating that the ship was over the
+south pole, one of the two chief centres of magnetism of the earth.
+
+"If we only dared stop to make some scientific notes and observations,"
+said the professor, "we could render much valuable aid to the seekers
+after truth. But it would be sure death to stay in the boiling water!"
+
+"I guess we'd better be getting out of this if we want to reach home
+alive," spoke Andy.
+
+Indeed they were all suffering very much, for the heat from the water
+was awful.
+
+"Speed her up, Washington!" called the professor. "We must get out of
+here!"
+
+"Which way shall I steer?" asked the colored man.
+
+"Straight ahead. We are now bound north!"
+
+"Bound north!" cried Jack.
+
+"Certainly," answered the professor. "We have passed over the exact spot
+where the south pole is. The deflecting needle is beginning to tilt
+again. The compass is indicating a northerly direction. You know that
+after you go as far south as you can, you have to begin to go back
+north. Well, we have gone as far south as we can. Now we are going
+north. We have turned the southern end of the globe, and are on our way
+back."
+
+For several hours the _Porpoise_ continued along on top of the water. By
+degrees, as they left the vicinity of the boiling ocean, it became
+cooler. The water ceased to seethe and bubble, and Jack found, on
+experiment, that he could bear his hand in it.
+
+"Hurrah!" he cried, "we are safe now."
+
+"Next we'll have to prepare to freeze to death," spoke Mark. "It's
+either one extreme or the other this trip. But we've had lots of fun and
+excitement."
+
+"Plenty of the last," agreed Jack.
+
+On and on went the submarine. Once it was out of the range of the
+terrible heated zone, the atmosphere rapidly cooled, until the
+adventurers were glad to don their heavy garments again.
+
+"This marks the ending of the first half of the voyage," announced the
+professor. "Now we are going back. We have accomplished something no
+other living man has done and I am proud of it. Proud of all of you, and
+proud of the ship!"
+
+Several hours later, when it was deemed safe, the _Porpoise_ was sunk
+beneath the waves, and once more she speeded along through the water at
+a fast speed. The ship seemed to know she was going home, for never had
+she made better time.
+
+"We have solved every problem that we met," said the professor while he,
+with Jack and Mark, were in the conning tower, as Washington was
+preparing a meal.
+
+"Except two," said Jack.
+
+"What are they?"
+
+"The ghost of the submarine, and the identity of the anarchists who blew
+up the Easton hotel."
+
+"Perhaps both riddles may be solved before we get back to Maine,"
+answered Mr. Henderson.
+
+They both were, sooner, and in stranger ways than either of the boys
+expected. That night it was Jack's first watch on deck. The ship was
+speeding on, and by the air the boy knew they were approaching icebergs.
+At midnight a strange and sudden chill in the air made him look up.
+
+Almost dead ahead was a big berg. He quickly shut off the engine, and
+narrowly avoided a collision. Then happening to glance back he saw,
+standing near the companionway leading down into the man-hole a ghostly
+white shape.
+
+"I'll find out what you are this time, or go overboard with you," said
+Jack to himself, clenching his teeth. He crawled along the deck until he
+thought he was within leaping distance of the weird white thing. Then he
+made a leap.
+
+He landed on something soft, which, the moment he struck it, let out a
+yell that sounded loud on the quiet night. Then the thing began to
+fight. But Jack fought back and held on bravely.
+
+"Here! What are you tryin' to do?" exclaimed a voice in his ear.
+
+"What are you trying to do?" asked Jack indignantly, finding that the
+words came from the "ghost."
+
+"Nice way to treat a man! Half kill him!" the white thing went on. "Just
+when I'm trying to get a little sleep you come along and pull me out of
+bed!"
+
+"Why, it's Bill Jones," exclaimed Jack, as the light from the conning
+tower lamp fell on the face of the "ghost."
+
+"Of course it is; who did you think it was?" asked Bill.
+
+"What are you doing on deck in your night shirt?" asked the boy, letting
+the helper rise.
+
+"Me? On deck? Ain't I in my bunk?"
+
+"I should say not," replied Jack. "What are you doing on deck?"
+
+"Well! well!" remarked Bill, rubbing his eyes. "I've gone and done it
+again."
+
+"Done what?"
+
+"Walked in my sleep. I'm a great sleep walker. Greatest you ever knew.
+Once I climbed to the top of our barn when I was asleep."
+
+"So you're the ghost of the submarine," exclaimed Jack. "That explains
+it."
+
+"I guess you're right," admitted Bill, as the others came on deck to see
+what all the row was about. "I never thought of it when I heard about
+the ghost, but I can account for it now. I'd get out of my bunk, wander
+out on deck, and then crawl back again. Of course, being barefoot, or in
+fur slippers, I made no sounds. I don't wonder you thought I was a
+spirit. Queer I didn't wake up after some of the things I went through."
+
+"And you always managed to get back to your bunk in time so that we
+never caught you at it," said Jack. "However, it's all over now."
+
+And so it was, for after that Bill tied a chair in front of his bunk,
+and if he did get out in his sleep he stumbled against it and awoke
+before he had gone far.
+
+Northward the _Porpoise_ continued on her journey. She entered a vast
+field of ice, and only her ability to sink below the surface enabled her
+to get through it unharmed. There were few adventures going home. Once a
+big whale rammed the ship, as had happened on the going voyage, and
+several times they were surrounded by hordes of wild polar fish and
+walrusses, but there were no accidents, and in a couple of weeks the
+ship entered the temperate zone.
+
+Then came lazy happy days of sailing through the tropical region. They
+landed at several islands and renewed their supply of food.
+
+"I'm coming back this way some day," observed Mr. Henderson one
+afternoon as the ship was sailing along on top of the waves.
+
+"What for?" asked Jack.
+
+"To investigate that strange island with a big hole in the middle that
+seems to lead to the centre of the earth," was the answer. "I have a
+fancy we can explore that by means of a balloon. I'm going to try."
+
+"Will you take us along?" asked the two boys.
+
+"I'll see," replied the professor.
+
+And later on he did take them on a trip, a thousand miles
+underground,--but that is another story to tell.
+
+It was about a week later that the voyagers came within sight of Key
+West.
+
+"Off there lies the United States," said Mr. Henderson.
+
+"Hurrah for home!" cried Mark.
+
+Three days later they landed at a small Florida town. The sight of the
+_Porpoise_ attracted throngs of people to the dock where she tied up.
+Among them was a newsboy.
+
+"Get me all the papers for the past month," said Jack. "I want to see
+what the news is."
+
+"Same here," put in Mark, and the papers were soon brought.
+
+"Hurrah!" exclaimed Jack, as soon as he had looked at several of the
+sheets.
+
+"What is it?" asked Mark, who was unfolding a paper.
+
+"Anarchists Confess," read Jack. "Two Englishmen Admit They Blew Up
+Hotel Where Lord Peckham Was Stopping. No Suspicion Attaches to Two
+Youths Who So Mysteriously Disappeared!"
+
+"Hurrah!" joined in Mark.
+
+"Those are only the head lines," went on Jack. "There's a long story,
+and I guess it lets us out."
+
+The two boys were completely cleared of the slightest shade of suspicion
+of the outrage, and there was even an interview with the English
+detective in which he admitted that he was wrong.
+
+A week later the _Porpoise_ tied up at her own dock, whence she was
+launched.
+
+"Back again," remarked the professor as he stepped ashore. "I've been to
+the south pole, and to the north pole. I wonder where I shall go next?"
+
+"To the big hole and underground," suggested Jack.
+
+"We shall see," said Mr. Henderson with a twinkle in his eyes.

+Updated editions will replace the previous one--the old editions

+
+Creating the works from public domain print editions means that no
+one owns a United States copyright in these works, so the Foundation
+(and you!) can copy and distribute it in the United States without
+permission and without paying copyright royalties. Special rules,
+set forth in the General Terms of Use part of this license, apply to
+copying and distributing Project Gutenberg-tm electronic works to
+protect the PROJECT GUTENBERG-tm concept and trademark. Project
+Gutenberg is a registered trademark, and may not be used if you
+charge for the eBooks, unless you receive specific permission. If you
+do not charge anything for copies of this eBook, complying with the
+rules is very easy. You may use this eBook for nearly any purpose
+such as creation of derivative works, reports, performances and
+research. They may be modified and printed and given away--you may do
+practically ANYTHING with public domain eBooks. Redistribution is
+subject to the trademark license, especially commercial
+redistribution.

+PLEASE READ THIS BEFORE YOU DISTRIBUTE OR USE THIS WORK
+
+To protect the Project Gutenberg-tm mission of promoting the free

+Gutenberg-tm License (available with this file or online at
+http://gutenberg.org/license).
+
+
+Section 1. General Terms of Use and Redistributing Project Gutenberg-tm
+electronic works
+
+1.A. By reading or using any part of this Project Gutenberg-tm
+electronic work, you indicate that you have read, understand, agree to
+and accept all the terms of this license and intellectual property
+(trademark/copyright) agreement. If you do not agree to abide by all
+the terms of this agreement, you must cease using and return or destroy
+all copies of Project Gutenberg-tm electronic works in your possession.
+If you paid a fee for obtaining a copy of or access to a Project
+Gutenberg-tm electronic work and you do not agree to be bound by the
+terms of this agreement, you may obtain a refund from the person or
+entity to whom you paid the fee as set forth in paragraph 1.E.8.
+
+1.B. "Project Gutenberg" is a registered trademark. It may only be
+used on or associated in any way with an electronic work by people who
+agree to be bound by the terms of this agreement. There are a few
+things that you can do with most Project Gutenberg-tm electronic works
+even without complying with the full terms of this agreement. See
+paragraph 1.C below. There are a lot of things you can do with Project
+Gutenberg-tm electronic works if you follow the terms of this agreement
+and help preserve free future access to Project Gutenberg-tm electronic
+works. See paragraph 1.E below.
+
+1.C. The Project Gutenberg Literary Archive Foundation ("the Foundation"
+or PGLAF), owns a compilation copyright in the collection of Project
+Gutenberg-tm electronic works. Nearly all the individual works in the
+collection are in the public domain in the United States. If an
+individual work is in the public domain in the United States and you are
+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed. Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work. You can easily comply with the terms of this agreement by
+keeping this work in the same format with its attached full Project
+Gutenberg-tm License when you share it without charge with others.
+
+1.D. The copyright laws of the place where you are located also govern
+what you can do with this work. Copyright laws in most countries are in
+a constant state of change. If you are outside the United States, check
+the laws of your country in addition to the terms of this agreement
+before downloading, copying, displaying, performing, distributing or
+creating derivative works based on this work or any other Project
+Gutenberg-tm work. The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.
+
+1.E. Unless you have removed all references to Project Gutenberg:
+
+1.E.1. The following sentence, with active links to, or other immediate
+access to, the full Project Gutenberg-tm License must appear prominently

+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:
+

+almost no restrictions whatsoever. You may copy it, give it away or
+re-use it under the terms of the Project Gutenberg License included
+with this eBook or online at www.gutenberg.org
+
+1.E.2. If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges. If you are redistributing or providing access to a work
+with the phrase "Project Gutenberg" associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1
+through 1.E.7 or obtain permission for the use of the work and the
+Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or

+permission of the copyright holder found at the beginning of this work.

+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.
+
+1.E.5. Do not copy, display, perform, distribute or redistribute this
+electronic work, or any part of this electronic work, without
+prominently displaying the sentence set forth in paragraph 1.E.1 with
+active links or immediate access to the full terms of the Project
+Gutenberg-tm License.
+
+1.E.6. You may convert to and distribute this work in any binary,
+compressed, marked up, nonproprietary or proprietary form, including any

+copy, a means of exporting a copy, or a means of obtaining a copy upon
+request, of the work in its original "Plain Vanilla ASCII" or other
+form. Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.

+ License. You must require such a user to return or

+ and discontinue all use of and all access to other copies of
+ Project Gutenberg-tm works.
+

+
+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH F3. YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.

+the defective work may elect to provide a replacement copy in lieu of a
+refund. If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund. If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+

+warranties or the exclusion or limitation of certain types of damages.
+If any disclaimer or limitation set forth in this agreement violates the
+law of the state applicable to this agreement, the agreement shall be

+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,

+harmless from all liability, costs and expenses, including legal fees,
+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, is critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive

+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at

+
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://pglaf.org/donate

+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
