The Wreck of the Titan, Morgan Robertson [best ebook reader ubuntu .TXT] 📗

do your work, but I doubt that you could do his. I need him; so you can take the prisoners home. You will undoubtedly retain command."

"Very good, sir," answered the disappointed youngster, trying to conceal his chagrin.

"I don't want you to feel badly about it. I know how you all felt toward me. But I'm on a roving commission. I have no wireless apparatus and no definite instructions. I've been lampooned and ridiculed in the papers, and I'm going to give them my answer—that is, as I said, if I'm any good. If I'm not I'll be sunk."

So when the engineer had announced his mastery of his part of the problem, and that there was enough of gasoline to cruise for two weeks longer, Smith departed with the torpedo-boat, and Metcalf began his search for the expected fleet.

It was more by good luck than by any possible calculation that Metcalf finally found the fleet. A steamer out of San Francisco reported that it had not been heard from, and one bound in from Honolulu said that it was not far behind—in fact had sent a shot or two. Metcalf shut off gasoline, waited a day, and saw the smoke on the horizon. Then he submerged to the awash condition, which in this boat just floated the searchlight out of water; and thus balanced, neither floating nor sinking nor rolling, but rising and falling with the long pulsing of the ground-swell, he watched through the periscope the approach of the enemy.

It was an impressive spectacle, and to a citizen of a threatened country a disquieting one. Nine high-sided battle-ships of ten-gun type—nine floating forts, each one, unopposed, able to reduce to smoking ruin a city out of sight of its gunners; each one impregnable to the shell fire of any fortification in the world, and to the impact of the heaviest torpedo yet constructed—they came silently along in line-ahead formation, like Indians on a trail. There were no compromises in this fleet. Like the intermediate batteries of the ships themselves, cruisers had been eliminated and it consisted of extremes, battle-ships, and torpedo-boats, the latter far to the rear. But between the two were half a dozen colliers, repair, and supply ships.

Night came down before they were near enough for operations, and Metcalf turned on his invisible light, expanding the beam to embrace the fleet in its light, and moved the boat to a position about a mile away from its path. It was a weird picture now showing in the periscope: each gray ship a bluish-green against a background of black marked here and there by the green crest of a breaking sea. Within Metcalf's reach were the levers, cranks, and worms that governed the action of the periscope and the light; just before him were the vertical and horizontal steering-wheels; under these a self-illuminating compass, and at his ear a system of push-buttons, speaking-tubes, and telegraph-dials that put him in communication with every man on the boat, each one of whom had his part to play at the proper moment, but not one of whom could see or know the result. The work to be done was in Metcalf's hands and brain, and, considering its potentiality, it was a most undramatic performance.

He waited until the leading flag-ship was within half a mile of being abreast; then, turning on a hanging electric bulb, he held it close to the eyepiece of the periscope, knowing that the light would go up the tube through the lenses and be visible to the fleet. And in a moment he heard faintly through the steel walls the sound transmitted by the sea of a bugle-call to quarters. He shut off the bulb, watched a wandering shaft of light from the flag-ship seeking him, then contracted his own invisible beam to a diameter of about three feet, to fall upon the flag-ship, and played it back and forth, seeking gun ports and apertures and groups of men, painting all with that blinding light that they could not see, nor immediately sense. There was nothing to indicate that he had succeeded; the faces of the different groups were still turned his way, and the futile searchlight still wandered around, unable to bring to their view the white tube with its cup-like base.

Still waving the wandering beam of white light, the flag-ship passed on, bringing along the second in line, and again Metcalf turned on his bulb. He heard her bugle-call, and saw, in varied shades of green, the twinkling red and blue lights of her masthead signals, received from the flag-ship and passed down the line. And again he played that green disk of deadly light upon the faces of her crew. This ship, too, was seeking him with her searchlight, and soon, from the whole nine, a moving network of brilliant beams flashed and scintillated across the sky; but not one settled upon the cause of their disquiet.

Ship after ship passed on, each with its bugle-call to quarters, each with its muster of all hands to meet the unknown emergency—the menace on a hostile coast of a faint white light on the port beam—but not one firing a shot or shell; there was nothing to fire at. And with the passing of the last of the nine Metcalf listened to a snapping and a buzzing overhead that told of the burning out of the carbons in the light.

"Good work for the expenditure," he murmured, wearily. "Let's see—two carbons and about twenty amperes of current, against nine ships at ten millions apiece. Well, we'll soon know whether or not it worked."

While an electrician rigged new carbons he rested his eyes and his brain; for the mental and physical strain had been severe. Then he played the light upon the colliers and supply ships as they charged by, disposing of them in the same manner, and looked for other craft of larger menace. But there were none, except the torpedo contingent, and these he decided to leave alone. There were fifteen of them, each as speedy and as easily handled as his own craft; and already, apprised by the signaled instructions from ahead, they were spreading out into a fan-like formation, and coming on, nearly abreast.

"The jig's up, chief," he called through a tube to the engineer. "We'll get forty feet down until the mosquitoes get by. I'd like to take a chance at them but there are too many. We'd get torpedoed, surely."

Down went the diving rudder, and, with a kick ahead of the engine, the submersible shot under, heading on a course across the path of the fleet, and in half an hour came to the surface. There was nothing in sight, close by, either through the periscope or by direct vision, and Metcalf decided to make for San Francisco and report.

It was a wise decision, for at daylight he was floundering in a heavy sea and a howling gale from the northwest that soon forced him to submerge again for comfort. Before doing so, however, he enjoyed one good look at the Japanese fleet, far ahead and to port. The line of formation was broken, staggered, and disordered; and, though the big ships were making good weather of it, they were steering badly, and on one of them, half-way to the signal-yard, was the appeal for help that ships of all nations use and recognize—the ensign, upside-down. Under the lee of each ship was snuggled a torpedo-boat, plunging, rolling, and swamped by the breaking seas that even the mighty bulk to windward could not protect them from. And even as Metcalf looked, one twisted in two, her after funnels pointing to port, her forward to starboard, and in ten seconds had disappeared.

Metcalf submerged and went on at lesser speed, but in comfort and safety. Through the periscope he saw one after the other of the torpedo-craft give up the fight they were not designed for, and ship after ship hoist that silent prayer for help. They yawed badly, but in some manner or other managed to follow the flag-ship, which, alone of that armada, steered fairly well. She kept on the course for the Golden Gate.

Even submerged Metcalf outran the fleet before noon, and at night had dropped it, entering the Golden Gate before daylight, still submerged, not only on account of the troublesome turmoil on the surface, but to avoid the equally troublesome scrutiny of the forts, whose searchlights might have caught him had he presented more to their view than a slim tube painted white. Avoiding the mines, he picked his way carefully up to the man-of-war anchorage, and arose to the surface, alongside the Delaware, now the flag-ship, as the light of day crept upward in the eastern sky.

"We knew they were on the coast," said the admiral, a little later, when Metcalf had made his report on the quarter-deck of the Delaware. "But about this light? Are you sure of all this? Why, if it's so, the President will rank you over us all. Mr. Smith came in with the prisoners, but he said nothing of an invisible light—only of a strong searchlight with which you set fire to the signal-yard."

"I did not tell him all, admiral," answered Metcalf, a little hurt at the persistence of the feeling. "But I'm satisfied now. That fleet is coming on with incompetents on the bridge."

"Well, we'll soon know. I've only one ship, but it's my business to get out and defend the United States against invaders, and as soon as I can steam against this gale and sea I'll go. And I'll want you, too. I'm short-handed."

"Thank you, sir. I shall be glad to be with you. But wouldn't you like to examine the light?"

"Most certainly," said the admiral; and, accompanied by his staff, he followed Metcalf aboard the submersible.

"It is very simple," explained Metcalf, showing a rough diagram he had sketched. "You see he has used my system of reflectors about as I designed it. The focus of one curve coincides with the focus of the next, and the result is a thin beam containing nearly all the radiations of the arc."

"Very simple," remarked the admiral, dryly. "Very simple indeed. But, admitting this strong beam of light that, as you say, could set fire to that sealer, and be invisible in sunshine, how about the beam that is invisible by night? That is what I am wondering about."

"Here, sir," removing the thick disk from around the light. "This contains the prisms, which refract the beam entirely around the lamp; and disperse it into the seven colors of the spectrum. All the visible light is cut out, leaving only the ultraviolet rays, and these travel as fast and as far, and return by reflection, as though accompanied by the visible rays."

"But how can you see it?" asked an officer. "How is the ship it is directed at made visible?"

"By fluorescence," answered Metcalf. "The observer is the periscope itself. Any of the various fluorescing substances placed in the focus of the object-glass, or at the optical image in front of the eyepiece, will show the picture in the color peculiar to the fluorescing material. The color does not matter."

"More simple still," laughed the admiral. "But how about the colored lights they saw?"

"Simply the discarded light of the spectrum. By removing this cover on the disk, the different colored rays shoot up. That was to attract attention. I used only white light through the periscope."

"And it was this invisible light that blinded so many men, which in your hands blinded the crews of the Japanese?" asked the admiral.

"Yes, sir. The ultraviolet rays are beneficial as a germicide, but are deadly if too strong."

"Lieutenant Metcalf," said the admiral, seriously, "your future in the service is secure. I apologize for laughing at you; but now that it's over and you've won, tell us about the spectacles."

"Why, admiral," responded Metcalf, "that
