"Another hypothesis suggested that it was a marine monster who thus upheaved the waters. But unless the beast had been born in the lake and had there grown to its gigantic proportions unsuspected, which was scarce possible, he must have come there from outside. Lake Kirdall, however, has no connection with any other waters. If this lake were situated near any of the oceans, there might be subterranean ca.n.a.ls; but in the center of America, and at the height of some thousands of feet above sea-level, this is not possible. In short, here is another riddle not easy to solve, and it is much easier to point out the impossibility of false explanations, than to discover the true one.
"Is it possible that a submarine boat is being experimented with beneath the lake? Such boats are no longer impossible today. Some years ago, at Bridgeport, Connecticut, there was launched a boat, The Protector, which could go on the water, under the water, and also upon land. Built by an inventor named Lake, supplied with two motors, an electric one of seventy-five horse power, and a gasoline one of two hundred and fifty horse power, it was also provided with wheels a yard in diameter, which enabled it to roll over the roads, as well as swim the seas.
"But even then, granting that the turmoil of Lake Kirdall might be produced by a submarine, brought to a high degree of perfection, there remains as before the question how could it have reached Lake Kirdall? The lake, shut in on all sides by a circle of mountains, is no more accessible to a submarine than to a sea-monster.
"In whatever way this last puzzling question may be solved, the nature of this strange appearance can no longer be disputed since the twentieth of June. On that day, in the afternoon, the schooner "Markel" while speeding with all sails set, came into violent collision with something just below the water level. There was no shoal nor rock near; for the lake in this part is eighty or ninety feet deep. The schooner with both her bow and her side badly broken, ran great danger of sinking. She managed, however, to reach the sh.o.r.e before her decks were completely submerged.
"When the "Markel" had been pumped out and hauled up on sh.o.r.e, an examination showed that she had received a blow near the bow as if from a powerful ram.
"From this it seems evident that there is actually a submarine boat which darts about beneath the surface of Lake Kirdall with most remarkable rapidity.
"The thing is difficult to explain. Not only is there a question as to how did the submarine get there? But why is it there? Why does it never come to the surface? What reason has its owner for remaining unknown? Are other disasters to be expected from its reckless course?"
The article in the Evening Star closed with this truly striking suggestion: "After the mysterious automobile, came the mysterious boat. Now comes the mysterious submarine.
"Must we conclude that the three engines are due to the genius of the same inventor, and that the three vehicles are in truth but one?"
Chapter 8
AT ANY COST
The suggestion of the Star came like a revelation. It was accepted everywhere. Not only were these three vehicles the work of the same inventor; they were the same machine!
It was not easy to see how the remarkable transformation could be practically accomplished from one means of locomotion to the other.
How could an automobile become a boat, and yet more, a submarine? All the machine seemed to lack was the power of flying through the air.
Nevertheless, everything that was known of the three different machines, as to their size, their shape, their lack of odor or of steam, and above all their remarkable speed, seemed to imply their ident.i.ty. The public, grown blase with so many excitements, found in this new marvel a stimulus to reawaken their curiosity.
The newspapers dwelt now chiefly on the importance of the invention.
This new engine, whether in one vehicle or three, had given proofs of its power. What amazing proofs! The invention must be bought at any price. The United States government must purchase it at once for the use of the nation. a.s.suredly, the great European powers would stop at nothing to be beforehand with America, and gain possession of an engine so invaluable for military and naval use. What incalculable advantages would it give to any nation, both on land and sea! Its destructive powers could not even be estimated, until its qualities and limitations were better known. No amount of money would be too great to pay for the secret; America could not put her millions to better use.
But to buy the machine, it was necessary to find the inventor; and there seemed the chief difficulty. In vain was Lake Kirdall searched from end to end. Even its depths were explored with a sounding-line without result. Must it be concluded that the submarine no longer lurked beneath its waters? But in that case, how had the boat gotten away? For that matter, how had it come? An insoluble problem!
The submarine was heard from no more, neither in Lake Kirdall nor elsewhere. It had disappeared like the automobile from the roads, and like the boat from the sh.o.r.es of America. Several times in my interviews with Mr. Ward, we discussed this matter, which still filled his mind. Our men continued everywhere on the lookout, but as unsuccessfully as other agents.
On the morning of the twenty-seventh of June, I was summoned into the presence of Mr. Ward.
"Well, Strock," said he, "here is a splendid chance for you to get your revenge."
"Revenge for the Great Eyrie disappointment?"
"Of course."
"What chance?" asked I, not knowing if he spoke seriously, or in jest.
"Why, here," he answered. "Would not you like to discover the inventor of this three-fold machine?"
"I certainly should, Mr. Ward. Give me the order to take charge of the matter, and I will accomplish the impossible, in order to succeed. It is true, I believe it will be difficult."
"Undoubtedly, Strock. Perhaps even more difficult than to penetrate into the Great Eyrie."
It was evident that Mr. Ward was intent on rallying me about my unsuccess. He would not do that, I felt a.s.sured, out of mere unkindness. Perhaps then he meant to rouse my resolution. He knew me well; and realized that I would have given anything in the world to recoup my defeat. I waited quietly for new instructions.
Mr. Ward dropped his jesting and said to me very generously, "I know, Strock, that you accomplished everything that depended on human powers; and that no blame attaches to you. But we face now a matter very different from that of the Great Eyrie. The day the government decides to force that secret, everything is ready. We have only to spend some thousands of dollars, and the road will be open."
"That is what I would urge."
"But at present," said Mr. Ward, shaking his head, "it is much more important to place our hands on this fantastic inventor, who so constantly escapes us. That is work for a detective, indeed; a master detective!"
"He has not been heard from again?"
"No; and though there is every reason to believe that he has been, and still continues, beneath the waters of Lake Kirdall, it has been impossible to find any trace of him anywhere around there. One would almost fancy he had the power of making himself invisible, this Proteus of a mechanic!"
"It seems likely," said I, "that he will never be seen until he wishes to be."
"True, Strock. And to my mind there is only one way of dealing with him, and that is to offer him such an enormous price that he cannot refuse to sell his invention."
Mr. Ward was right. Indeed, the government had already made the effort to secure speech with this hero of the day, than whom surely no human being has ever better merited the t.i.tle. The press had widely spread the news, and this extraordinary individual must a.s.suredly know what the government desired of him, and how completely he could name the terms he wished.
"Surely," added Mr. Ward, "this invention can be of no personal use to the man, that he should hide it from the rest of us. There is every reason why he should sell it. Can this unknown be already some dangerous criminal who, thanks to his machine, hopes to defy all pursuit?"
My chief then went on to explain that it had been decided to employ other means in search of the inventor. It was possible after all that he had perished with his machine in some dangerous maneuver. If so, the ruined vehicle might prove almost as valuable and instructive to the mechanical world as the man himself. But since the accident to the schooner "Markel" on Lake Kirdall, no news of him whatever had reached the police.
On this point Mr. Ward did not attempt to hide his disappointment and his anxiety. Anxiety, yes, for it was manifestly becoming more and more difficult for him to fulfill his duty of protecting the public.
How could we arrest criminals, if they could flee from justice at such speed over both land and sea? How could we pursue them under the oceans? And when dirigible balloons should also have reached their full perfection, we would even have to chase men through the air! I asked myself if my colleagues and I would not find ourselves some day reduced to utter helplessness? If police officials, become a useless inc.u.mbrance, would be definitely discarded by society?
Here, there recurred to me the jesting letter I had received a fortnight before, the letter which threatened my liberty and even my life. I recalled, also, the singular espionage of which I had been the subject. I asked myself if I had better mention these things to Mr. Ward. But they seemed to have absolutely no relation to the matter now in hand. The Great Eyrie affair had been definitely put aside by the government, since an eruption was no longer threatening.
And they now wished to employ me upon this newer matter. I waited, then, to mention this letter to my chief at some future time, when it would be not so sore a joke to me.
Mr. Ward again took up our conversation. "We are resolved by some means to establish communication with this inventor. He has disappeared, it is true; but he may reappear at any moment, and in any part of the country. I have chosen you, Strock, to follow him the instant he appears. You must hold yourself ready to leave Washington on the moment. Do not quit your house, except to come here to headquarters each day; notify me, each time by telephone, when you start from home, and report to me personally the moment you arrive here."
"I will follow orders exactly, Mr. Ward," I answered. "But permit me one question. Ought I to act alone, or will it not be better to join with me?"
"That is what I intend," said the chief, interrupting me. "You are to choose two of our men whom you think the best fitted."
"I will do so, Mr. Ward. And now, if some day or other I stand in the presence of our man, what am I to do with him?"
"Above all things, do not lose sight of him. If there is no other way, arrest him. You shall have a warrant."
"A useful precaution, Mr. Ward. If he started to jump into his automobile and to speed away at the rate we know of, I must stop him at any cost. One cannot argue long with a man making two hundred miles an hour!"
"You must prevent that, Strock. And the arrest made, telegraph me.
After that, the matter will be in my hands."
"Count on me, Mr. Ward; at any hour, day or night, I shall be ready to start with my men. I thank you for having entrusted this mission to me. If it succeeds, it will be a great honor--"
