"Barometer's up a tenth." His eyes did not quite focus. "All right, lieutenant. Go ahead. Promising young officer. Excellent. I'll sit down here for just a moment." When Barnes came back, Hardwick was asleep. And a last one hundred and fifty frozen sausages of brine and ship-fuel went out of Headquarters within a matter of hours, and then a vast quietude settled down everywhere. Young Barnes sat beside Hardwick, menacing anybody who even thought of disturbing him. When Sandringham called for him. Barnes went to the phone-plate. "Sir," he said with vast formality. "Mr. Hardwick went five days without sleep. His job's done. I won't wake him, sir!" Sandringham raised his eyebrows. "You won't?" "I won't, sir!" said young Barnes. Sandringham nodded. "Fortunately," he observed, "nobody's listening. You are quite right." He snapped the connection. And then young Barnes realized that he had defied a Sector Chief, which is something distinctly more improper in a junior officer than merely trying to instruct him in topping off his vacuum-suit tanks. * * * * * Twelve hours later, however, Sandringham called for him. "Barometer's dropping, lieutenant. I'm concerned. I'm issuing a notice of the impending storm. Not everybody will crowd in on us, but a great many will. I'm explaining that the chemicals put into the bottom soil may not quite have finished their work. If Hardwick wakens, tell him." "Yes, sir," said Barnes. But he did not intend to wake Hardwick. Hardwick, however, woke of himself at the end of twenty hours of sleep. He was stiff and sore and his mouth tasted as if something had kittened in it. Fatigue can produce a hangover, too. "How's the barometer?" he asked when his eyes came open. "Dropping, sir. Heavy winds, sir. The Sector Chief has opened the Reserve Area, sir, to the civilians if they wish to come." Hardwick computed dizzily on his fingers. A more complex instrument was actually needed, of course. One does not calculate on one's fingers just how long a one per cent solution of ship-fuel in frozen brine has taken to melt, and how completely it has diffused through an upside-down swamp with the pressure of forty feet of soil on top of it, and therefore its effective concentration and dispersal underground. "I think," said Hardwick, "it's all right. By the way, did they turn the irrigation systems hind end to?" Young Barnes did not know what this was all about. He had to send for information. Meanwhile he solicitously plied Hardwick with coffee and food. Hardwick grew reflective.
