 Which of these is true about the importance of alge to the Martians?
Should any groundsman dispute the importance of belly-furniture in history—whether it be exterminating whales, or introducing syphilis to the Fiji Islanders, or settling the Australian littoral with cross-coves from Middlesex and Hampshire—he is referred to the hundred-and-first chapter of Moby Dick , a book spooled in the amusement tanks of all but the smallest spacers. The Triton made her underwater periplus of Earth with a galley stocked with frozen pizza and concentrated apple-juice. Four officers and twenty-one Other Ranks were rescued from the Ajax in deep space, half dead from deuterium poisoning. And for a third footnote to the ancient observation, "God sends food, and the Devil sends cooks," Marsmen will recall what happened aboard my ship the Charles Partlow Sale . In no special hurry, we were taking the low-energy route to Mars, a pathway about as long in time as the human period of gestation. Cooking aboard a spacer is a job combining the more frustrating tensions of biochemistry, applied mycology, high-speed farming, dietetics and sewage engineering. This isn't just a paragraph from the Spacer Union Contract. Twelve tons of water, oxygen, and food would have filled the cargo compartments to bursting, and left a small ship like the C. P. Sale no reason to reach for Mars. By allowing a colony of Chlorella algae to work over our used air, water and other effluvia, though, three tons of metabolites would see us through from Brady Station to Piano West and back.
