 According to the narrator, who is the most important figure onboard a spacecraft?
Food, on the other hand, is a challenge shipmen face three times a day, so central to their thoughts that a history of sea-faring can be read from a commissary list. 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 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. Cooking aboard a spacer is a job combining the more frustrating tensions of biochemistry, applied mycology, high-speed farming, dietetics and sewage engineering. It's the Cook's responsibility to see that each man aboard gets each day no less than five pounds of water, two pounds of oxygen, and one-and-a-half pounds of dry food. 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. Generally the man aboard who'd serve as the most popular murder-victim is the Cook. This trip, the-man-you-love-to-hate was our Captain.
