II
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.
When he had gone I plunged at once into the task of learning the control and operation of our craft. The next two hours I spent under the tutelage of Sarto Sen, and at the end of that time I had already learned the essential features of the ship's control. There was a throttle which regulated the frequency of the vibrations generated in the engine-room below, thus increasing or decreasing our speed at will, and a lever and dial which were used to project the propelling vibrations out at any angle behind us, thus controlling the direction in which we moved. The main requisite in handling the craft, I found, was a precise and steady hand on the two controls, since a mere touch on one would change our speed with lightning swiftness, while a slight movement of the other would send us millions of miles out of our course almost instantly.
At the end of two hours, however, I had attained sufficient skill to be able to hold the cruiser to her course without any large deviations or changes of speed, and Sarto Sen had confidence enough in my ability to leave me alone at the controls. He departed down the little stair behind me, to give a few minutes' inspection to the generators below, and I was left alone in the conning-tower.
Standing there in the dark little room, its only sound the deep humming of the generators below and its only lights the hooded glows which illuminated the dials and switches before me, I gazed intently through the broad fore-window, into that crowding confusion of swarming suns that lay around us, that medley of jeweled fires in which the great star Alto burned like a living flame. For a long time I gazed toward the star that was our goal, and then my thoughts were broken into by the sound of Sarto Sen reascending the stair behind me. I half turned to greet him, then turned swiftly back to the window, stiffening into sudden attention.
My eyes had caught sight of a small patch of deep blackness far ahead, an area of utter darkness which was swiftly expanding, growing, until in less than a second, it seemed, it had blotted out half the thronging stars ahead. For a moment the sudden appearance of it dumfounded me so that I stood motionless, and then my hands leaped out to the controls. I heard Sarto Sen cry out, behind me, and had a glimpse of the darkness ahead, obscuring almost all the heavens. The next moment, before my hands had more than closed upon the levers, all light in the conning-tower vanished in an instant, and we were plunged into the most utter darkness which I have ever experienced. At the same moment the familiar hum of the vibration-generators broke off suddenly.
I think that the moment that followed was the one in which I came first to know the meaning of terror. Every spark of light had vanished, and the silencing of the vibration-generators could only mean that our ship was drifting blindly through this smothering blackness. From the cruiser's hull, below, came shouts of fear and horror, and I heard Sarto Sen feeling his way to my side and fumbling with the controls. Then, with startling abruptness, the lights flashed on again in the conning-tower and through the windows there burst again the brilliance of the starry heavens. At the same moment the vibration-generators began again to give off their deep humming drone.
Sarto Sen turned to me, his face white as my own. Instinctively we turned toward the conning-tower's rear-window, and there, behind us, lay that stupendous area of blackness from which we had just emerged. A vast, irregular area of utter darkness, it was decreasing rapidly in size as we sped on away from it. In a moment it had shrunk to the spot it had been when first I glimpsed it, and then it had vanished entirely. And again we were racing on through the familiar, star-shot skies.
