The rest of that transit was twelve on and twelve off for Bill and me, and every minute I was awake I was afraid I might follow Mike down Lunacy Lane. Or that he might get loose. A couple of times we brought him awake, but each time we were glad we'd turned extra air pressure into his cushions. He struggled, and by watching his lips we knew he was still raving. The calculations for landing spiral made us sweat. We'd left the astrogation to Mike so completely we'd gotten rusty. We missed him even more making contact. I had to handle both throttles and calculator while Bill took the cumbersome Luminophone mechanism. It took hours to line up the color-modulated beam, and then in typical Martian fashion more hours for them to answer with a landing clearance. But at last the _Banshee_ scrunched into the red desert just outside T'lith, and as the Wilsons died Bill and I wiggled our fingers in our ears to get them back to normal. Within a few minutes a dozen Martians were striding toward us from the beehive-domes of their city. They came straight as though walking ruled lines, not hurrying and not lagging, semi-human in outline and size. A couple of hundred feet from the ship they deployed and began to watch. Then we could see their bulging, faceted eyes, their puckered, three-lipped mouths and the two rodlike antennae that waved slowly back and forth on their greenish foreheads. We didn't know then why they watched, or who--or what--told them to watch. But always there were a dozen on hand whenever a spaceship landed, watching in a passive, detached way with neither approval nor disapproval in their manner. They watched, just as the Cultural Emissaries on Earth kept an eye on everything that happened without asking a single question or interfering in any way that we could see. Bill opened the port and gobbled at the watchers in their own language, telling them we wanted to pick up a cargo of rhudite ore and had Earth gadgets to exchange. They didn't give any sign they heard us, but we didn't expect them to. The answer, if it came at all, would come minutes or even hours later. We didn't know why. Not then. We'd never heard of the Thing. Bill pulled his head in again, and while we waited we turned off Mike's sleep gas once more. This time we really had a faint hope that with the Wilsons off he'd be himself. But his first words were, "Will you damned fools turn me loose? I'm not crazy! We've got to do something, and quick. Hell, I don't want to be like a damned Martie! They don't get any fun out of life." He started to kick and squirm, so we gassed him out again. It seemed the only merciful thing to do. "Olsen," Bill said thoughtfully. "We can't leave him alone and one of us has to rustle up a cargo." "You're elected. You know the lingo better than I do." "You don't mind?"
