And he'd had to choose this time to leave Earth!
Suddenly he was glad he was assigned to the tubes. It was the one place on the ship where he'd be least likely to run into her. As a doctor and a courtesy passenger, she'd have complete run of the ship, but she'd hardly bother with the dangerous and unpleasant tube section.
He dragged his way back, beginning to sweat with the effort. The Navaho was an old ship. A lot of the handholds were missing, and he had to throw himself along by erratic leaps. He was gaining proficiency, but not enough to handle himself if the ship blasted off. Time was growing short when he reached the aft bunkroom where the other tubemen were waiting.
"Ben," one husky introduced himself. "Tube chief. Know how to work this?"
Feldman could see that they were assembling a small still. He'd heard of the phenomenal quantities of beer spacemen drank, and now he realized what really happened to it. Hard liquor was supposed to be forbidden, but they made their own. "I can work it," he decided. "I'm—uh—Dan."
"Okay, Dan." Ben glanced at the clock. "Hit the sacks, boys."
By the time Feldman could settle into the sacklike hammock, the Navaho began to shake faintly, and weight piled up. It was mild compared to that on the shuttle, since the big ships couldn't take high acceleration. Space had been conquered for more than a century, but the ships were still flimsy tubs that took months to reach Mars, using immense amounts of fuel. Only the valuable plant hormones from Mars made commerce possible at the ridiculously high freight rate.
Three hours later he began to find out why spacemen didn't seem to fear dying or turning pariah. The tube quarters had grown insufferably hot during the long blast, but the main tube-room was blistering as Ben led the men into it. The chief handed out spacesuits and motioned for Dan.
"Greenhorn, aincha? Okay, I'll take you with me. We go out in the tubes and pull the lining. I pry up the stuff, you carry it back here and stack it."
They sealed off the tube-room, pumped out the air, and went into the steaming, mildly radioactive tubes, just big enough for a man on hands and knees. Beyond the tube mouth was empty space, waiting for the man who slipped. Ben began ripping out the eroded blocks with a special tool. Feldman carried them back and stacked them along with others. A plasma furnace melted them down into new blocks. The work grew progressively worse as the distance to the tube-room increased. The tube mouth yawned closer and closer. There were no handholds there—only the friction of a man's body in the tube.
