CHAPTER XV
A BOLT FROM THE SKY
“Are we gaining on them, Jerry?” asked the professor eagerly, when thechase had been on for several minutes.
“Oh, I can easily catch up to them, and pass them; but that’s just thetrouble, I don’t want to do that,” replied the tall lad. “If we getbeyond them we’d have to turn, and then we might lose sight of them. Idon’t know what to do if they won’t be friendly and let us come aboard.”
“They could easily fool us by just sinking,” spoke Ned. “I don’t seewhy they don’t do that instead of trying to run away from us on thesurface. If that submarine captain knows anything about physics he mustknow that an object can travel through the air quicker than it can inwater.”
“That’s right,” agreed Bob, “but he’s going along at a pretty goodclip.”
This was indeed so. The submarine was fairly flying over the surface ofthe sea, a smother of foam at her stern showing where the propeller,or whatever form of propulsion she used, was working, while at herblunt nose was a long ripple as the water was pushed away on either bow.
“She is certainly making time,” conceded Jerry. “She must have powerfulengines.”
“I guess those aboard her were watching us all the time,” came fromNed. “They just waited until they saw us getting too close, and thenthey started off.”
“Yes, but what I can’t understand,” observed Jerry, “is why they don’tdive, if they want to have us guessing. If she went down, even a fewfeet, we couldn’t see her, and she might come up ten miles from here.Then we would be out of it.”
“That’s right,” admitted Ned. “But perhaps they had to come upfor fresh air, and their tanks aren’t quite filled yet. Of courseoxygen can be manufactured aboard a submarine, but you can’t breatheartificial air forever--you’ve got to have fresh air, especially ifthey run gasoline engines, as they probably do, though the main onesmay be operated by electricity from a storage battery.”
“Why do they need so much air for gasoline engines?” asked Bob.
“Because gasoline won’t explode unless it’s mixed with air. The enginesimply must have it. So that’s why they’re probably staying on thesurface so long--to renew the air in the compression tanks to feed tothe motors.”
On and on rushed the submarine, but there was no more sign of life fromwithout than there had been at first. Nor could the boys understand howthey themselves had been observed.
“Well, something will happen, sooner or later,” said Jerry, as hefollowed the course of the craft below them. “And if nothing else doesit will be darkness coming on, so we’ll lose sight of her.”
“What about the search-light?” asked Bob.
“That will help some, but this submarine is about the color of water,anyhow, and it isn’t going to be the easiest thing in the world tofollow her after dark, even with our powerful light.”
“Oh, boys, I do hope we won’t lose her!” exclaimed Professor Snodgrass.“I may never have such a chance again to get in a submarine and lookfor those hermit crabs. Don’t lose her if you can help it.”
“I won’t,” answered Jerry, “but it isn’t going to be easy. Besides, shemay, as I said, dive any minute!”
But at present the submarine seemed to have no such intention. She spunalong through the water, with the airship following her overhead, Jerrykeeping the speed of his craft at such a point as would not cause himto over-run the boat.
“Say, we’re forgetting all about my uncle!” exclaimed Bob at length.“What are we going to do about him?”
“I don’t see that we can do anything, Chunky, my boy!” exclaimed Jerry.“There’s no doubt that he and his daughter have been picked up by somesteamer, and they may be in port before we get back home. In fact,after we try out this submarine a bit I think the best thing we can dois to put back to Cresville. I’m sure you’ll find your uncle and cousinwaiting there for you.”
“I’m sure I hope so,” returned Bob. “Well, as long as there’s nothingfor me to do, I think I’ll----”
“Get something to eat!” interrupted Ned. “Now, don’t get mad, Chunky,I’d like some myself; how about it, Jerry?”
“Yes, go as far as you like in the galley, Bob. I’ll eat when grub isready, but just now I’m anxious to see how this chase is coming out.”
“Look!” cried Ned, suddenly. “I guess this ends it!”
As he spoke he pointed below. They all looked, and as they did so theysaw the submarine suddenly sink. Her blunt nose seemed to poke itselfbeneath the waves, and in a few seconds all that showed where thestrange craft had been were some bubbles and foam on the surface of theheaving sea.
“She’s gone!” cried the professor, in disappointed tones.
“I thought she’d do that,” murmured Jerry. “Well, that settles it asfar as we are concerned.”
“You’re not going to give up; are you?” Professor Snodgrass wanted toknow. “I simply must have a submarine to get those hermit crabs.”
“Well, it will all be a matter of luck, anyhow, finding this oneagain,” spoke Ned. “I guess, Professor, it will be easier for us tobuild you one, or buy a second-hand boat, if there are any such.”
“Anything, so as I can get to the bottom of the sea,” sighed thescientist, still looking at the place where the mysterious submarinehad disappeared.
“Get busy with supper, Bob!” called Jerry, as he set the automaticsteering gear. “There’s nothing else to do now except eat.”
“And after that?” asked Ned.
“Oh, we’ll hang around here for a few days, and then, if we don’t seeany more of the _Hassen’s_ lifeboats, with some of the passengers orcrew, or if we don’t sight the submarine once more, I think we may aswell go back home,” replied Jerry. “Bob will want to see his uncle, andthe folks will get anxious about us if we stay out too long.”
“You seem pretty sure my uncle is safe ashore,” spoke the stout lad.
“I am,” declared Jerry. “You’ll soon be able to satisfy your curiosityregarding that valuable object he brought over with him.”
“I have been wondering what it could be,” admitted Bob. “It’s a familysecret, I know that much, and it’s valuable. Well, I may as well getsupper, I suppose,” and he finished his remarks in such a naive waythat Ned and Jerry laughed.
As for Professor Snodgrass, now that his hope of getting on thesubmarine was dashed, he went back to his beloved labor of catching anystray bugs and insects that might be aboard the _Comet_, or which hecould net out of the air.
Supper was progressing satisfactorily, various appetizing odors thatcame from the galley testifying to Bob’s activities. Jerry and Nedlooked to see if the machinery was running properly and then they keptwatch down below for a possible sight of the boat that had eluded them.
But it would soon be too dark to see, and Jerry decided thatthe chances of picking up the craft in the rays of the powerfulsearch-light were too small to make up for the discomfort that would becaused by standing watch all night.
“We’ll just let her go, and trust to luck for finding her again,” hesaid. “Evidently she is cruising about in these waters, and the chancesare just as good for finding her again by accident as they would be ifwe made a search. Luck goes in threes, anyhow, you know, fellows. We’veseen her twice when we least expected it, and I believe we’ll see heragain. Now I’m going to take it easy,” and he stretched out on a sofain the living cabin, through the glass floor of which glimpses could behad of the ocean below them.
Preparations for the evening meal were well under way, and the _Comet_was shooting along at good speed. The boys were thinking of manythings. Ned and Jerry were wondering if it would be possible for themto get a submarine, while Bob, during such time as his attention wastaken from his cooking, was wondering if his uncle and cousin weresafely home, and what it was Mr. Sheldon had brought from Germany.
Suddenly from the bow of the ship, where Professor Snodgrass had goneto look for specimens, there came a cry of pa
in. Ned and Jerry leapedto their feet.
“What is it?” cried the tall youth, running forward.
“Have you caught something?” asked Ned eagerly.
“Ha! It would be more correct to say that something has caught me!”returned the professor. “Hurry, boys, it’s a great big beetle, and he’spinching me. I daren’t knock him off because I want him for a specimen.Oh, how he pinches!”
The two chums saw a comical sight--or, it would have been funny had itnot been for the look of pain on the face of the scientist.
He stood near the pilot house, an insect net under one arm, and acyanide bottle--for painlessly killing his specimens--under the other.His left hand was tightly closed, while, dangling from the other wasa large, black and squirming bug, that seemed to be hanging on bythe simple process of making his pincers meet in the flesh of theprofessor’s thumb.
“Oh, boys! Take him off! He is hurting me dreadfully!” cried thescientist. “But be very careful, as he is a most rare and valuablespecimen.”
“Why don’t you take him off yourself--you know how to handle thosecreatures,” suggested Ned, who did not much fancy plucking off thevicious-looking black beetle.
“I--I can’t,” said the professor. “I have a new kind of upper-air flyin this other hand, and if I open it he’ll get away. I had caught that,and was reaching for the beetle, when he pinched me. I’m glad he’sholding on, though, for it will give you a chance to get him.”
“Uh--I don’t know as I want to,” replied Ned, hanging back. “He mighttransfer his affections to me.”
“Oh, please get him!” begged the scientist.
“I’ll show you how,” said Jerry. “Let me get that cyanide bottle fromunder your arm, Professor. I’ll open it and hold it near the beetle.The fumes will stupefy him, and he’ll drop in. Then I can cork him up.”
“Good!” cried Professor Snodgrass.
Jerry took the poison bottle, which contained in the bottom plaster ofParis, mixed with the deadly cyanide of potassium. The fumes of thisare deadly to all insects in a very short time, killing them withoutpain.
Holding the open bottle close under the beetle that was clinging tothe professor’s thumb, but taking care to keep his own face well awayfrom the vial, Jerry waited. In a few seconds the pincers of the beetlerelaxed. A few seconds more and it fell off into the wide-mouthedbottle. Jerry quickly corked it up, and handed it to the professor.
“Ah, thank you, my boy, thank you!” exclaimed the scientist. “That is avery rare specimen. I am glad to get it.”
“As glad as he was to get you,” said Jerry with a smile. “It certainlyis a large beetle.”
“And he certainly pinched,” murmured the professor, rubbing his thumb,on which were a few drops of blood. “I think I had better use a littleperoxide to avoid infection.”
This excitement over, supper was served. As they all stood on the maindeck, with darkness settling down, Jerry, looking over to the west,while the motorship moved slowly along, remarked:
“I think we’re in for a storm. I saw a flash of lightning just then.”
“Bur-r-r-r!” exclaimed Ned with a little shiver. “I don’t fancy a blowin this exposed place.”
“Oh, I guess we can weather it,” spoke Jerry.
“Anyhow, I’m glad my uncle and cousin are not out in an open boat,”added Bob.
Jerry’s prophecy of a storm was borne out. It came up rapidly and soonthere was quite a gale of wind, while the lightning flashes grew moreand more frequent. The accompanying thunder roared alarmingly.
It grew darker rapidly, and the storm seemed likely to last through thenight. Rain began to fall, but the boys did not mind that.
Everything was made snug aboard the craft, which scudded along throughthe blackness of the night, illuminated by the flashes from the sky.
“I wonder where that submarine is now?” said Bob musingly.
“Probably far down beyond the influence of the waves,” answered Jerry.
It must have been about midnight, when none of those on the _Comet_ hadcared to turn in that, following several slight flashes, there cameone of vivid brilliancy. There was that same crackling sound at first,as the boys had noticed once before, and then a terrific crash, thatseemed to split right through the airship.
In an instant the hum of the propeller motor ceased, and the benumbedboys and Professor Snodgrass, unable to move for a second, soparalyzing had been the shock, felt the craft sinking with them towardthe ocean.
“We’ve been struck!” cried Jerry. “We’re disabled!”
“Yes, and we’re going down!” yelled Ned.
Down and down went the crippled _Comet_, down through the storm thatwas crashing all around her.
