Five minutes later I strode with Sarto Sen and Hal Kur into the landing-court where lay the new cruiser, its long, fishlike hull glittering brilliantly in the sunlight. A door in its side snapped open as we drew near, and through it there stepped out to meet us one of the six blue-clad engineers who formed the craft's crew. "All is ready for the start," he said to Sarto Sen in reply to the latter's question, standing aside for us to enter.
We passed through the door into the cruiser's hull. To the left an open door gave me a glimpse of the ship's narrow living-quarters, while to the right extended a long room in which other blue-clad figures were standing ready beside the ship's shining, conelike vibration-generators. Directly before us rose a small winding stairway, up which Sarto Sen led the way. In a moment, following, we had reached the cruiser's conning-tower, and immediately Sarto Sen stepped over to take his place at the controls.
He touched a stud, and a warning bell gave sharp alarm throughout the cruiser's interior. There were hurrying feet, somewhere beneath us, and then a loud clang as the heavy triple-doors slammed shut. At once began the familiar throb-throb-throb of the oxygen pumps, already at work replenishing and purifying the air in our hermetically sealed vessel.
Sarto Sen paused for a moment, glancing through the broad window before him, then reached forth and pressed a series of three buttons. A low, deep humming filled the cruiser's whole interior, and there was an instant of breathless hesitation. Then came a sharp click as Sarto Sen pressed another switch; there was a quick sigh of wind, and instantly the sunlit landing-court outside vanished, replaced in a fraction of a second by the deep, star-shot night of interplanetary space. I glanced quickly down through a side window and had a momentary glimpse of a spinning gray ball beneath us, a ball that dwindled to a point and vanished even in the moment that I glimpsed it. It was Earth, vanishing behind us as we fled with frightful velocity out into the gulf of space.
We were hurtling through the belt of asteroids beyond Mars, now, and then ahead, and to the left, there loomed the mighty world of Jupiter, expanding quickly into a large white-belted globe as we rocketed on toward it, then dropping behind and diminishing in its turn as we sped past it. The sun behind us had dwindled by that time to a tiny disk of fire. An hour later and another giant world flashed past on our right, the icy planet Neptune, outermost of the Eight Worlds. We had passed outside the last frontier of the solar system and were now racing out into the mighty deeps of space with the speed of light on our mad journey to save a universe.

An hour after we had left the solar system Hal Kur and I still stood with Sarto Sen in the cruiser's conning-tower, staring out with him at the stupendous panorama of gathered stars that lay before us. The sun of our own system had dwindled to a far point of light behind us, by that time, one star among the millions that spangled the deep black heavens around us. For here, even more than between the planets, the stars lay before us in their true glory, undimmed by proximity to any one of them. A host of glittering points of fire, blue and green and white and red and yellow, they dotted the rayless skies thickly in all directions, and thronged like a great drift of swarming bees toward our upper left, where stretched the stupendous belt of the Milky Way. And dead ahead, now, shone a single orb that blazed in smoky, crimson glory, a single great point of red fire. It was Alto, I knew, the sullen-burning star that was our goal.
It was with something of unbelief that I gazed at the red star, for though the dials before me assured me that we were speeding on toward it at close to two hundred thousand miles a second, yet except for the deep humming of the craft's vibratory apparatus one would have thought that the ship was standing still. There was no sound of wind from outside, no friendly, near-by planets, nothing by which the eye could measure the tremendous velocity at which we moved. We were racing through a void whose very immensity and vacancy staggered the mind, an emptiness of space in which the stars themselves floated like dust-particles in air, a gulf traversed only by hurtling meteors or flaring comets, and now by our own frail little craft.
Though I was peculiarly affected by the strangeness of our position, big Hal Kur was even more so. He had traveled the space-lanes of the solar system for the greater part of his life, and now all of his time-honored rules of interplanetary navigation had been upset by this new cruiser, a craft entirely without gravity-screens, which was flashing from sun to sun propelled by invisible vibrations only. I saw his head wagging in doubt as he stared out into that splendid vista of thronging stars, and in a moment more he left us, descending into the cruiser's hull for an inspection of its strange propulsion apparatus.
