"Go to it!" The captain waved his hand and the operative bent to his task.
"Commanders of all vessels of the Fleet!" The Headquarters speaker, receiver sealed upon the wave-length of the Admiral of the Fleet, broke the long silence. "All vessels in sectors L to R, inclusive, will interlock location signals. Some of you have received, or will receive shortly, certain communications from sources which need not be mentioned. Those commanders will at once send out red K4 screens. Vessels so marked will act as temporary flagships. Unmarked vessels will proceed at maximum to the nearest flagship, grouping about it in the regulation squadron cone in order of arrival. Squadrons most distant from objective point designated by flagship observers will proceed toward it at maximum; squadrons nearest it will decelerate or reverse velocity—that point must not be approached until full Fleet formation has been accomplished. Heavy and light cruisers of all other sectors inside the orbit of Mars...." The orders went on, directing the mobilization of the stupendous forces of the League, so that they would be in readiness in the highly improbable event of the failure of the massed power of seven sectors to reduce the pirate base.
In those seven sectors perhaps a dozen vessels threw out enormous spherical screens of intense red light, and as they did so their tracer points upon all the interlocked lookout plates also became ringed about with red. Toward those crimson markers the pilots of the unmarked vessels directed their courses at their utmost power; and while the white lights upon the lookout plates moved slowly toward and clustered about the red ones the ultra-instruments of the Service operatives were probing into space, sweeping the neighborhood of the computed position of the pirate's stronghold.
But the object sought was so far away that the small spy-ray sets of the Service men, intended as they were for close range work, were unable to make contact with the invisible planetoid for which they were seeking. In the captain's sanctum of the Chicago, the operative studied his plate for only a minute or two, then shut off his power and fell into a brown study, from which he was rudely aroused.
"Aren't you even going to try to find them?" demanded the captain.
"No," Cleve returned shortly. "No use—not half enough power or control. I'm trying to think ... maybe ... say, Captain, will you please have the Chief Electrician and a couple of radio men come in here?"
They came, and for hours, while the other ultra-wave men searched the apparently empty ether with their ineffective beams, the three technical experts and the erstwhile Quartermaster's clerk labored upon a huge and complex ultra-wave projector—the three blindly and with doubtful questions; the one with sure knowledge at least of what he was trying to do. Finally the thing was done, the crude, but efficient graduated circles were set, and the tubes glowed redly as their massed output drove into a tight beam of ultra-vibration.
"There it is, sir," Cleve reported, after some ten minutes of manipulation, and the vast structure of the miniature world flashed into being upon his plate. "You may notify the fleet—coordinates H 11.62, RA 124-31-16, and Dx about 173.2."
The report made and the assistants out of the room, the captain turned to the observer and saluted gravely.
"We have always known, sir, that the Service had men; but I had no idea that any one man could possibly do, on the spur of the moment, what you have just done—unless that man happened to be Lyman Cleveland."
"Oh, it doesn't...." the observer began, but broke off, muttering unintelligibly at intervals; then swung the visiray beam toward the Earth. Soon a face appeared upon the plate; the keen, but careworn face of Virgil Samms!
"Hello, Lyman," his voice came clearly from the speaker, and the Captain gasped—his ultra-wave observer and sometime clerk was Lyman Cleveland himself, probably the greatest living expert in beam transmission! "I knew that you'd do something, if it could be done. How about it—can the others install similar sets on their ships? I'm betting that they can't."
"Probably not," Cleveland frowned in thought. "This is a patchwork affair, made of gunny sacks and hay-wire. I'm holding it together by main strength and awkwardness, and even at that, it's apt to go to pieces any minute."
"Can you rig it up for photography?"
"I think so. Just a minute—yes, I can. Why?"
"Because there's something going on out there that neither we nor apparently the pirates know anything about. The Admiralty seems to think that it's the Jovians again, but we don't see how it can be—if it is, they have developed a lot of stuff that none of our agents has even suspected," and he recounted briefly what Costigan had reported to him, concluding: "Then there was a burst of interference—on the ultra-band, mind you—and I've heard nothing from him since. Therefore I want you to stay out of the battle entirely. Stay as far away from it as you can and still get good pictures of everything that happens. I will see that orders are issued to the Chicago to that effect."
"But listen...."
"Those are orders!" snapped Samms. "It is of the utmost importance that we know every detail of what is going to happen. The answer is pictures. The only possibility of obtaining pictures is that machine you have just developed. If the fleet wins, nothing will be lost. If the fleet loses—and I am not half as confident of success as the Admiral is—the Chicago doesn't carry enough power to decide the issue, and we will have the pictures to study, which is all-important. Besides, we have probably lost Conway Costigan today, and we don't want to lose you, too."
Cleveland remained silent, pondering this startling news, but the grizzled Captain, veteran of the Fourth Jovian War that he was, was not convinced.
"We'll blow them out of space, Mr. Samms!" he declared.
"You just think you will, Captain. I have suggested, as forcibly as possible, that the general attack be withheld until after a thorough investigation is made, but the Admiralty will not listen. They see the advisability of withdrawing a camera ship, but that is as far as they will go."
"And that's plenty far enough!" growled the Chicago's commander, as the beam snapped off. "Mr. Cleveland, I don't like the idea of running away under fire, and I won't do it without direct orders from the Admiral."
"Of course you won't—that's why you are going...."
He was interrupted by a voice from the Headquarters speaker. The captain stepped up to the plate and, upon being recognized, he received the exact orders which had been requested by the Chief of the Triplanetary Service.
Thus it was that the Chicago reversed her acceleration, cut off her red screen, and fell rapidly behind, while the vessels following her shot away toward another crimson-flaring loader. Farther and farther back she dropped, back to the limiting range of the mechanism upon which Cleveland and his highly-trained assistants were hard at work. And during all this time the forces of the seven sectors had been concentrating. The pilot vessels, with their flaming red screens, each followed by a cone of space-ships, drew closer and closer together, approaching the Fearless—the British super-dreadnought which was to be the flagship of the Fleet—the mightiest and heaviest space-ship which had yet lifted her stupendous mass into the ether.
Now, systematically and precisely, the great Cone of Battle was coming into being; a formation developed during the Jovian Wars while the forces of the Three Planets were fighting in space for their very civilizations' existence, and one never used since the last space-fleets of Jupiter's murderous hordes had been wiped out.
The mouth of that enormous hollow cone was a ring of scout patrols, the smallest and most agile vessels of the fleet. Behind them came a somewhat smaller ring of light cruisers, then rings of heavy cruisers and of light battleships, and finally of heavy battleships. At the apex of the cone, protected by all the other vessels of the formation and in best position to direct the battle, was the flagship. In this formation every vessel was free to use her every weapon, with a minimum of danger to her sister ships; and yet, when the gigantic main projectors were operated along the axis of the formation, from the entire vast
