message would have reached her directly but where there are only a hundred of you, true social networking is mouth to mouth.
In-Aunt Milaba. She was a legend, a statue of woman, gracious and noble, adored far beyond West Diggory. Her dark skin was lustrous as night, her soul as star-filled. To be in her presence was to be blessed in ways you would not immediately understand but, more thrilling to Tash, was that In-Aunt Milaba was the chief service engineer for the North West sector scooplines. The summons to her office, a little glass and aluminium bubble like a bunion on one of West Diggory’s steel feet, could mean only one thing. Out. Out and up.
“So Haramwe sprained his ankle.”
Every part of In-Aunt Milaba’s tiny office, from the hand-carved olivine desk to the carafe of water that stood on it, shook to the rattle of the buckets hurtling up the scoopline. Milaba raised an eyebrow. Tash realised a response was due.
“Are his injuries debilitating?”
“Debilitating.” Milaba gave a flicker of a smile. “You could say that. He’ll be out for a week or so. He came down heavily, silly boy. Showing off. When is your birthday?” Tash’s heart leapt.
She knew. Everyone knew everything, all the time. The game was pretending not to know.
“Octobril fifth.”
“Three months.” Milaba appeared to consider for a moment. “Peyko Ruebens-Opollo says for all your fancy talk you’ve a good head and better sense and do what you’re told. That’s good because I don’t need attitude problems or last-minute-good-ideas when I’m out on the line.”
For once the words failed Tash. They hissed from her like air from a ruptured atmosphere cell. She waved her hands in speechless delight.
“I’m taking a digger up Line 12 to Windrush Valley. The feed tokamaks have been fluctuating nastily. Probably a soft fail in a command chip set; they get a lot of radiation up there. Now I need someone with me to hold things and make tea and generally make intelligent conversation. Are you interested?”
Still the words would not come. The rule was that you did not leave the Excavating Cities until you were eight, when you were technically adult. Rules broke and bent with the frequency of scoopline breakdowns but three months was a significant proportion of the long Martian year. Out. Out, and up. Up the line, into the windy valley. In a diggler, with In-Aunt Milaba.
“Yes, oh yes, I’d love to,” Tash finally squeaked. Now Milaba unleashed the full radiance of her smile and it was like sunrise, it was solstice lights, it was the warmth of the glow-lamps in the Orangery.
“Be at the Outlock 12 at fourteen o’clock,” Milaba said. “You do know how to make tea, don’t you?”
Still not got it? It’s easy, easy easy easy. Easy as a heezy, which is a Digger saying. A heezy is the lever on a scoopline bucket that, when struck by the dohbrin (which is a different type of lever found at the load-off end of the scoopline) tips the contents of the bucket down Mt. Incredible. Heezy peasy easy. It’s all because air has weight. Air’s not nothing. It’s gas—in Mars’ case, carbon dioxide nitrogen argon oxygen and the leaked breathings from the hundred-and-something years that humans have scratched and scrabbled clawholds on its red earth. It has mass. It has weight. And it flows, the same way that water flows, to the lowest point. Wind is air flowing. People say,
Thirty kilometres deep. The scooplines are at minus twenty six kilometres. That’s another five M-years before they hit atmospheric baseline. Then they’ll level out the floor of the crater, take away some of the sides, expand the flat area, though it will all seem so flat, the atmospheric gradient so subtle, that you will seem to be walking out into breathlessness and light-headedness rather than ascending into it. Fifty years after her In-Grandfather Tayhum made the first incision, the Big Dig will be dug. Tash will be seventeen and a half when the wind rushing down the sides of the Big Dig finally fails and the rotors stop and the banners fall and the Excavating Cities finally come to a rest.
Twenty six kilometres up slope, In-Aunt Milaba gave the sign for Tash to throw the levers to disengage the diggler from the scoopline. Thus far the big world of outside had been a thumping disappointment to Tash. She had yet to be outside, properly outside, two-figures-in-a-Mars-scape outside, shiver-in-your-psuit outside. She had transited from plastic bubble by plastic tube to plastic bubble connected by its grip on the scoopline to home.
This was what Tash Gelem-Opunyo saw from the transparent bubble of the diggler. Sand sand sand sand sand, a rock there, sand sand sand rock rock, oh, some pebbles! Sand grit sand more grit something between pebble and grit, something between grit and sand, a bit of old abandoned machinery, wow wow wow! Dust drifted up around it. Sand. Sand. Sand. West Diggory was still visible, down the dwindling thread of the scoopline, now truly the size of a spider. The enormous, horizonless perspectives robbed Tash of anything by which she could judge movement. The sand, the buckets, the unchanging gentle gradient that went up halfway to space. Only by squinting down through the floor glass at the blurred, grainy surface did she get any sense of movement.
Twenty-six vertical kilometres equalled two hundred sixty surface kilometres equalled five and a half hours in a plastic bubble with a relative you’ve grown up in enforced proximity to but until now never really known or talked to. Everyone loves In-Aunt Milaba the Magnificent, that’s the legend, but five hours, Aunt and Niece, Tash began to wonder if this was another wind-whisper legend blown around the corners and crannies of West Diggory. She was beautiful, a feast for the eye and soul, all those things an eight-year-old girl hopes for herself (and did Tash not share the DNA—given that the Excavating cities genepool was shallow as a spit, hence all the careful arrangements of In-relatives and Out-relatives and who would be sent to one of the other Excavating Cities and who would stay) all those things a girl of almost-eight wants for herself but try as she might, and did, Tash could not engage her. Fancy funny words of the type Tash treasured. Poems. Puns. Riddles. Guessing games. Break-the-code-games. Allusions and circumspect questions. Direct questions. To them all In-Aunt Milaba shook her head and smiled and bent over the controls and the monitors and checked her kit and said not a word. So tea, lots of tea, and muttering little rhymes to the rhythm of the huge balloon wheels as the scoopline hauled Diggler Six up the side of the biggest excavation in the solar system.
But now they were released from the scoopline and Milaba was standing at the steering column, driving the diggler under its own power. It was still sand sand sand and occasional rock, but Tash knew a gnaw of excitement. She was free, disconnected from the umbilicals of life for the first time. She was out in the wild world. The scoopline dwindled to a thread, to invisibility behind her, ahead she saw a notch on the edge of vision. Windrush Valley. All the wind-blown words stopped. A flaw in the horizon. A place beyond the Big Dig. Beyond that declivity was the whole curved world. In the silence In-Aunt Milaba turned from the control column.
“I think you could have a go now.”
So this was what she had been waiting for, Tash to run out of words, and finally listen.
The diggler was ridiculously simple to drive. Plant your feet firmly at the drive column. Push forward to feed power to the traction motors in the wheel hubs. Pull back to brake. Yaw to steer. There was even a little holder on the side of the drive column for your tea. Tash giggled with nervous glee as she gingerly pushed forward the stick and the bubble of pressure glass slung between the giant orange tyres stuttered forward. Within thirty seconds she
