beam, LSV3, to reach us. Barring a touch of an unusually severe type of space-sickness, everything worked beautifully; even better than either of us dared to believe. There's something we want to know right away—have we been gone four hours and some odd minutes, or better than two years?"

      He turned to Rodebush and went on:

      "Nobody knows how fast this ultra-wave travels, but if it goes as fast as we did coming out it's no creeper. I'll give him about thirty minutes, then shoot in another...."

      But, interrupting Cleveland's remark, the care-ravaged face of Virgil Samms appeared sharp and clear upon the plate and his voice snapped curtly from the speaker.

      "Thank God you're alive, and twice that that the ship works!" he exclaimed. "You've been gone four hours, eleven minutes, and forty one seconds, but never mind about abstract theorizing. Get back here, to Pittsburgh, as fast as you can drive. That Nevian vessel or another one like her is mopping up the city, and has destroyed half the Fleet already!"

      "We'll be back there in nine minutes!" Rodebush snapped into the transmitter. "Two to get from here to atmosphere, four from Atmosphere down to the Hill, and three to cool off. Notify the full four-shift crew—everybody we've picked out. Don't need anybody else. Ship, equipment, and armament are ready!"

      "Two minutes to atmosphere? Think you can do it?" Cleveland asked, as Rodebush flipped off the power and leaped to the control panel. "You might, though, at that."

      "We could do it in less than that if we had to. We used scarcely any power at all coming out, and I'm going to use quite a lot going back," the physicist explained rapidly, as he set the dials which would determine their flashing course.

      The master switches were thrown and the pangs of inertialessness again assailed them—but weaker far this time than ever before—and upon their lookout plates they beheld a spectacle never before seen by eye of man. For the ultra-beam, with its heterodyned vision, is not distorted by any velocity yet attained, as are the ether-borne rays of light. Converted into light only at the plate, it showed their progress as truly as though they had been traveling at a pace to be expressed in the ordinary terms of miles per hour. The yellow star that was the sun detached itself from the firmament and leaped toward them, swelling visibly, momently, into a blinding monster of incandescence. And toward them also flung the Earth, enlarging with such indescribable rapidity that Cleveland protested involuntarily, in spite of his knowledge of the peculiar mechanics of the vessel in which they were.

      "Hold it, Fred, hold it! Way 'nuff!" he exclaimed.

      "I'm using only a few thousand kilograms of thrust, and I'll cut that as soon as we touch atmosphere, long before she can even begin to heat," Rodebush explained. "Looks bad, but we'll stop without a jar."

      "What would you call this kind of flight, Fritz?" Cleveland asked. "What's the opposite of 'inert'?"

      "Damned if I know. Isn't any, I guess. Light? No ... how would 'free' be?"

      "Not bad. 'Free' and 'Inert' maneuvering, eh? O.K."

      Flying "free", then, the super-ship came from her practically infinite velocity to an almost instantaneous halt in the outermost, most tenuous layer of the Earth's atmosphere. Her halt was but momentary. Inertia restored, she dropped at a sharp angle downward. More than dropped; she was forced downward by one full battery of projectors; projectors driven by iron-powered generators. Soon they were over the Hill, whose violet screens went down at a word.

      Flaming a dazzling white from the friction of the atmosphere through which she had torn her way, the Boise slowed abruptly as she neared the ground, plunging toward the surface of the small but deep artificial lake below the Hill's steel apron. Into the cold waters the space-ship dove, and even before they could close over her, furious geysers of steam and boiling water erupted as the stubborn alloy gave up its heat to the cooling liquid. Endlessly the three necessary minutes dragged their slow way into time, but finally the water ceased boiling and Rodebush tore the ship from the lake and hurled her into the gaping doorway of her dock. The massive doors of the airlocks opened, and while the full crew of picked men hurried aboard with their personal equipment, Samms talked earnestly to the two scientists in the control room.

      "... and about half the fleet is still in the air. They aren't attacking; they are just trying to keep her from doing much more damage until you can get there. How about your take-off? We can't launch you again—the tracks are gone—but you handled her easily enough coming in?"

      "That was all my fault," Rodebush admitted. "I had no idea that the fields would extend beyond the hull. We'll take her out on the projectors this time, though, the same as we brought her in—she handles like a bicycle. The projector blast tears things up a little, but nothing serious. Have you got that Pittsburgh beam for me yet? We're about ready to go."

      "Here it is, Doctor Rodebush," came Norma's voice, and upon the screen there flashed into being the view of the events transpiring above that doomed city. "The dock is empty and sealed against your blast."

      "Goodbye, and power to your tubes!" came Samms' ringing voice.

      As the words were being spoken mighty blasts of power raved from the driving projectors, and the immense mass of the super-ship shot out through the portals and upward into the stratosphere. Through the tenuous atmosphere the huge globe rushed with ever-mounting speed, and while the hope of Triplanetary drove eastward Rodebush studied the ever-changing scene of battle upon his plate and issued detailed instructions to the highly trained specialists manning every offensive and defensive weapon.

      But the Nevians did not wait to join battle until the newcomers arrived. Their detectors were sensitive—operative over untold thousands of miles—and the ultra-screen of the Hill had already been noted by the invaders as the Earth's only possible source of trouble. Thus the departure of the Boise had not gone unnoticed, and the fact that not even with his most penetrant rays could he see into her interior had already given the Nevian commander some slight concern. Therefore as soon as it was determined that the great globe was being directed toward Pittsburgh the fish-shaped cruiser of the void went into action.

      High in the stratosphere, speeding eastward, the immense mass of the Boise slowed abruptly, although no projector had slackened its effort. Cleveland, eyes upon interferometer grating and spectrophotometer charts, fingers flying over calculator keys, grinned as he turned toward Rodebush.

      "Just as you thought, Skipper; an ultra-band pusher. C4V63L29. Shall I give him a little pull?"

      "Not yet; let's feel him out a little before we force a close-up. We've got plenty of mass. See what he does when I put full push on the projectors."

      As the full power of the Tellurian vessel was applied the Nevian was forced backward, away from the threatened city, against the full drive of her every projector. Soon, however, the advance was again checked, and both scientists read the reason upon their plates. The enemy had put down reenforcing rods of tremendous power. Three compression members spread out fanwise behind her, bracing her against a low mountainside, while one huge tractor beam was thrust directly downward, holding in an unbreakable grip a cylinder of earth extending deep down into bedrock.

      "Two can play at that game!" and Rodebush drove down similar beams, and forward-reaching tractors as well. "Strap yourselves in solid, everybody!" he sounded in general warning. "Something is going to give way somewhere soon, and when it does we'll get a jolt!"

      And the promised jolt did indeed come soon. Prodigiously massive and powerful as the Nevian was, the Boise was even more massive and more powerful; and as the already enormous energy feeding the tractors, pushers, and projectors was raised to its inconceivable maximum, the vessel of the enemy was hurled upward, backward; and that of Earth shot ahead with a bounding leap that threatened to strain even her mighty members. The Nevian anchor rods had not broken; they had simply pulled up the vast cylinders of solid rock that had formed their anchorages.

      "Grab him now!" Rodebush yelled, and even while an avalanche of falling rock was burying the countryside Cleveland snapped a tractor ray upon the flying fish and pulled tentatively.

      Nor did the Nevian now seem averse to coming
