In that instant of clear visibility, however, Rovol's mighty mind had photographed every salient visible feature of the great cruiser of the void. Being almost at the limit of range of the projector, details were of course none too plain; but certain things were evident. The human beings were no longer aboard; the little lifeboat that was _Skylark Two_ was no longer in her spherical berth; and there were unmistakable signs of a purposeful and deliberate departure. "And," Rovol spoke aloud as he removed the headset, "although we searched minutely and most carefully all the surrounding space we could find nothing tangible. From these observations it is all too plain that Seaton was attacked by some intelligence wielding dirigible forces of the sixth order; that he was able to set up a defensive pattern; that his supply of power-uranium was insufficient to cope with the attacking forces; and that he took the last desperate means of escaping from his foes by rotating _Skylark Two_ into the unknown region of the fourth dimension." DuQuesne's stunned mind groped for a moment in an amazement akin to stupefaction, but he recovered quickly and decided upon his course. "Well, what are you doing about it?" he snapped. "We have done and are doing everything possible for us, in our present state of knowledge and advancement, to do," Rovol replied placidly. "We sent out forces, as I told you, which obtained and recorded all the phenomena to which they were sensitive. It is true that a great deal of data escaped them, because the primary impulses originated in a level beyond our present knowledge, but the fact that we cannot understand it has only intensified our interest in the problem. It shall be solved. After its solution we shall know what steps to take and those steps shall then be taken." "Have you any idea how long it will take to solve the problem?" "Not the slightest. Perhaps one lifetime, perhaps many--who knows? However, rest assured that it shall be solved, and that the condition shall be dealt with in the manner which shall best serve the interest of humanity as a whole." "But good heavens!" exclaimed DuQuesne. "In the meantime, what of Seaton and Crane?" He was now speaking his true thoughts. Upon this, his first encounter, he could in nowise understand the deep, calm, timeless trend of mind of the Norlaminians; not even dimly could he grasp or appreciate the seemingly slow but inexorably certain method in which they pursued relentlessly any given line of research to its ultimate conclusion. "If it should be graven upon the sphere that they shall pass they may--and will--pass in all tranquility, for they know full well that it was not in idle gesture that the massed intellect of Norlamin assured them that their passing should not be in vain. You, however, youths of an unusually youthful and turbulent race, could not be expected to view the passing of such a one as Seaton from our own mature viewpoint."
