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 Secret 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 Secret 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 solidly massed output was driving into a tight beam of ultra-vibration. "There it is, sir," Cleve reported, after some ten minutes of delicate manipulation, and the vast structure of the miniature world flashed into being upon his plate. "You may notify the fleet--co-ordinates 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."
