 What is the narrator's profession?
It's true that Woman remains a topic of thoughtful study, but discussion can never replace practice in an art. 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. 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. Cooking aboard a spacer is a job combining the more frustrating tensions of biochemistry, applied mycology, high-speed farming, dietetics and sewage engineering. Though I'm signed aboard as Ship's Surgeon, I seldom lift a knife in space. My duties are to serve as wailing-wall, morale officer, guardian of the medicinal whiskey and frustrator of mutual murder.
