"S ... p ... a ... r ... k ... s," Lancelot Biggs was left-righting to me, "g ... o ... t t ... o b ... e b ... r ... i ... e ... f. Power limited. Tell Chief line inner hull posi-charge steel lining, throw nega-circuit through outer. Have Todd revise course to following trajectory...." I'll spare you the rest. It was all technical. So technical, in fact, that I couldn't make head or tail of it. There wasn't a man aboard the _Saturn_ who could. It was, furthermore, absolute proof that we were dealing with no spook, but with L. Biggs himself. For this was typical "Biggsian" mathematics. And he was right in saying his time was short. He was beginning to fade before he had completed the algebraic and mechanical formulæ he wigwagged to me. Toward the end I had to strain my eyes to find out which hand he was wiggling. But I caught the last waves. "Follow instructions blindly," he signaled, "and we'll soon be together again. Luck! My love ... Diane...." Then he was gone. * * * * * Boy, now, I'll tell you the following hours were hectic. Our normal complement is a twenty-men crew, of which only six men are engineers or engine-room helpers. And the job Biggs had laid out for us was weighty enough to stagger the resources of a Patrol repairship. But Hanson turned on the heat, and when the Old Man shoots the juice, things hop! We drafted everyone on board. Staff, crew, engine-room, Ordinaries--even Slops and the mess boy burned blisters on the pinkies performing the task Biggs had assigned us. Most of us bent to our labors eagerly. Myself, for instance--I didn't know what Biggs had in mind, or what the final result of our efforts would be. But I knew damned well that Biggs never gave purposeless orders. Some good would be the end of this fantastic webwork of plates, wires and coils we were weaving through, in and about the _Saturn_. Diane, despite the fact that her hands soon became raw and sore, insisted on doing a share of the manual labor. "I must, Sparks!" she declared. "I'd never respect myself again if I didn't help in some small way. Because he promised this would bring us together again. Where, I don't know--" She straightened, staring at me speculatively. "I don't know!" she whispered. "Sparks--he never told us where he is!" "He didn't have time," I reassured her. "His power was limited, he said. But everything's going to be O.Q." But later, Dick Todd raised the same point, when I spoke to him in the control-turret. He had been checking the course Biggs had designated. Now, frowning, he laid his computations before me. "You see what this means, Bert?" "Yeah," I said, looking at the rumpled sheet. "It means you ought to wash your hands more often. Well, what?" "This course," said Todd nervously, "sets a direct trajectory to--_Jupiter_!" I said, "O.Q. So it sets a direct traj--_What did you say?_"
