Although it had taken four lighters, this trip, to bring down to the Poe the shipment of manufactured goods and scientific samples from the Moon, only one lighter was required for the return shipment. The Moon colony was not yet self-supporting, but the first steps in that direction had already been made. A part of the colony's food was home-grown, hydroponically. New plant buildings and new machinery were built right on the Moon, by firms whose only customers were other Moon companies. Clothing and furnishings were made of synthetics. Most of the Moon-bound cargo was paperwork, of one sort or another. There was the fifteen days accumulation of mail for the Moon personnel, sheafs of new product specifications for the managers of the Moon plants, financial reports, and so on. The rest, except for the cargo for QB, was primarily food, meat and dairy products and other foods unavailable through hydroponics. There were also three engineers, new employees of Interplanetal Business Machines, replacing three men whose two-year contracts were ending and who would be coming back to Earth on the next transit. * * * * * Blair greeted the three men at the lighter ramp, checking their names and identity cards against the manifest and then saying, "My name's Blair, Glenn Blair. I'm Cargomaster on this trip, and you boys are part of the cargo. You've got any questions or problems, bring them to me. I'm liaison between you and the rest of the Transit personnel. Okay?" One of the engineers said, "If we decide we can't take it we shouldn't bug the working types, is that it?" "You're Ricks? Yes, Ricks, that's exactly it. None of you people have been off-planet before, so you can't make any sure statements about how you'll act. A good quarter of our first-time passengers are plenty scared. It's nothing to be ashamed of. If any of you feel it getting to you come to me. Don't try to burrow your way through the wall, don't try to kill yourself, don't go running around screaming. We've had all of that, at one time or another, and it plays merry hell with the working day." Ricks grinned. "If I need a shoulder to cry on, Mister Blair," he said, "I'll run straight to you." "You do that. Come on, I'll show you your quarters." Blair led the way up the ramp and into the lighter. The bottom half of the ship was engine and fuel-space, and most of the upper half was cargo hold, leaving only two levels at the top for human occupancy. The uppermost level was the control room, with passenger space on the level beneath. The three engineers, Ricks in the lead, followed Blair up the inside ladder to the second level, a smallish circular room with twelve bunks, in tiers of three, around the walls. The center space was empty. "There's only four of us," said Blair, "so we can all take middle bunks. The middle's best; there's less noise and vibration." "Beds for the babies, is that it?" said Ricks.
