Somewhat to Kinnison's surprise—he had more than half expected that planets would be nonexistent in that space—the pilots did find a solid world upon which to land. It was a peculiar planet indeed. It did not move right, it did not look right, it did not feel right. It was waterless, airless, desolate; a senseless jumble of jagged fragments, mostly metallic. It was neither hot nor cold—indeed, it seemed to have no temperature of its own at all. There was nothing whatever right about it, Kinnison declared.
"Oh, yes, there is!" Thorndyke contradicted. "Time is constant here, whatever its absolute rate may be, these metals are nice to work with, and some of this other stuff will make insulation. Or hadn't you thought of that? Which would be faster, cutting down an intrinsic velocity of fifteen lights to zero or building the projector out of native materials? And if you match intrinsics, what will happen when you hit our normal space again?"
"Plenty, probably ... uh-huh, faster to use the stuff that belongs here. Careful, though, fella!"
And care was indeed necessary; extreme care that not a particle of matter from the ship was used in the construction and that not a particle of the planet's substance by any mischance got aboard the spaceship.
The actual work was simple enough. Cardynge knew exactly what had to be done. Thorndyke knew exactly how to do it, as he had built precisely similar generators for the experimental tubes upon Tellus. He had a staff of experts; the Dauntless carried a machine shop and equipment second to none. Raw material was abundant, and it was an easy matter to block out an inertialess room within which the projectors and motors were built. And, after they were built, they worked.
It was not the work, then, but the strain which wore Kinnison down. The constant, wearing strain of incessant vigilance to be sure that the Bergenholms and the small units of the personal neutralizers did not falter for a single instant. He did not lose a man, but again and again there flashed into his mind the ghastly picture of one of his boys colliding with the solid metal of the planet at a relative velocity fifteen times that of light! The strain of the endless checking and rechecking to make certain that there was no exchange of material, however slight, between the ship and the planet.
Above all, the strain of knowing a thing which, apparently, no one else suspected: that Cardynge, with all his mathematical knowledge, was not going to be able to find his way back! He had never spoken of this to the scientist. He did not have to. He knew that without a knowledge of the fundamental distinguishing characteristics of our normal space—a knowledge even less to be expected than that a fish should know the fundamental equations and structure of water—they never could, save by sheerest accident, return to their own space. And as Cardynge grew more and more tensely, unsocially immersed in his utterly insoluble problem, the more and more uneasy the Gray Lensman became. But this last difficulty was resolved first, and in a totally unexpected fashion.
"Ah, Kinnison of Tellus, here you are—I have been considering your case for some twenty-nine of your seconds," a deep, well-remembered voice resounded within his brain.
"Mentor!" he exclaimed, and at the sheer shock of his relief he came very near indeed to fainting. "Thank Klono and Noshabkeming you found us! How did you do it? How do we get ourselves out of here?"
