Leaving him to his watch over the ship's flight, I descended to the cruiser's interior, where the engineers were still discussing with Hal Kur the experience through which we had just passed. In a few words I explained to them Sarto Sen's theory, and they went back to their posts with awed faces. Passing into the ship's living-quarters myself, I threw myself on a bunk there and strove to sleep. Sleep came quickly enough, induced by the generators' soothing drone, but with it came torturing nightmares in which I seemed to move blindly onward through endless realms of darkness, searching in vain for an outlet into the light of day. When I awoke some six hours later, the position of the ship seemed quite unchanged. The steady humming of its generators, the smooth, onward flight, the legions of dazzling stars around us, all seemed as before. But when I ascended again to the conning-tower, to relieve Sarto Sen at the controls, I saw that already the star Alto had increased a little its brilliance, dimming the stars around and behind it. And through the succeeding hours of my watch in the conning-tower, it seemed to me almost that the red orb was expanding before my sight, as we hurtled on toward it. That, though, I knew to be only an illusion of my straining eyes. But as day followed day—sunless, dawnless days which we could measure only by our time-dials—the crimson star ahead waxed steadily to greater glory. By the time we marked off the twentieth day of our flight Alto had expanded into a moon of crimson flame, whose sullen splendor outrivaled the brilliance of all the starry hosts around us; for by that time we had covered half the distance between our own sun and the dying one ahead, and were now flashing on over the last half of our journey. Days they were without change, almost without incident. Twice we had sighted vast areas of blackness, great ether-cavities like the one we had first plunged through, but these we were fortunate enough to avoid, swerving far out of our course to pass them by. Once, too, I had glimpsed for a single moment a colossal black globe which flashed beside our path for an instant and then was left behind by our tremendous speed. Only a glimpse did I get of this dark wanderer, which might have been either a runaway planet or burned-out star. And once our ship blundered directly into a vast maelstrom of meteoric material, a mighty whirlpool of interstellar wreckage spinning there between the stars, and from which we won clear only by grace of Sarto Sen's skilful hands at the controls. Except for these few incidents, though, our days
