 Which of these is true about the importance of alge to the Martians?
It's true that Woman remains a topic of thoughtful study, but discussion can never replace practice in an art. And today we Marsmen are called Slimeheads, honoring in our title the Chlorella and Scenedesmus algae that, by filling up the spaces within, open the road to the larger Space without. 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. I trust, however, that no Marsman will undertake to review this inventory of refreshment more than a week from groundfall. The Triton made her underwater periplus of Earth with a galley stocked with frozen pizza and concentrated apple-juice. Long before I was a boy in Med School, itching to look at black sky through a view-port, galley science had fulfilled the disgusting exordium of Isaiah 36:12, to feed the Slimeheads for breakfast today what was day-before-yesterday's table-scraps and jakes-water. The Ship's Cook, the man who accomplishes the daily miracle of turning offal into eatables, is in many ways the most vital man aboard a spacer. 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. Our cargo consisted mostly of Tien-Shen fir seedlings and some tons of an arctic grass-seed—these to be planted in the maria to squeeze out the native blue bugberry vines.
