The Long War

The party dropped off supplies for the logging team, and brought up samples of exotic lichen in little plastic packs, lichen taken from very old trees. Old trees were rare on Datum Earth and were becoming so even on the heavily logged Low Earths. That was the nature of the trade across the “Long Mississippi’, as Helen had learned the pilots called this stepwise route. Raw materials flowed in towards the Datum—timber, foodstuffs, minerals—but bulk goods mostly came from the Corn Belt worlds further in, and only rare or precious items were worth bringing in from beyond the half-million-step mark, such as unique old-tree lichens and other exotic flora and fauna. Indeed, Joshua suggested as they watched this trade proceed, their own community ought to think about exporting Hell-Knows-Where maple liquor. In exchange the Datum shipped out low-mass but high-tech goods, from medical kit to electrical generators, to coils of fibre-optic cable so the colonists could establish decent communication networks in their new worlds. It was the kind of trade that had always characterized the settlement of new territories, such as between Britain and its American colonies before the Revolution, with high-quality manufactured products being sent out from the homeland in return for raw materials. Helen’s father and his Footprint Congress buddies would probably claim it was exploitative. Maybe, but it seemed to Helen to work.

And besides, whoever was ripping off whom, it had to be a good thing for this great river of airships to be linking all the worlds of mankind together. So Helen thought, anyhow.

Twelve days out from Valhalla and they crossed a diffuse boundary into the Corn Belt, the great band of farming worlds a third of a million steps thick, stretching in towards the Datum from about four hundred and sixty thousand worlds out. The skies were a lot busier now, with twains like their own heading towards the Datum passing those heading back out, “upstream’, so to speak.

The Gold Dust had made pretty fast progress to this point, but from now on the stops would be more frequent. There were waystations spread out stepwise all along the Long Mississippi, and further down the river geographically too, in many of these worlds. Helen was told that as they approached the Datum these stations would show up more frequently. At the waystations the twains stopped to take on cargo loads gathered here from the nearby worlds for collection. Sacks of corn were the staple export from these particular Earths, and the crews, with plenty of troll labour, worked in chains to get the twains’ gaping holds loaded up. The stations had inns and the like for rest and recreation. These weren’t polite places, Helen observed. Many of them had a calaboose, a little jailhouse.

One waystation they stopped at, however, was in a world that happened to be a little warmer than the rest, and the owners had taken the opportunity to establish sprawling sugar plantations and orange groves and palmettos, rare this far north in any America. The sugar-house where they processed their cane was a huge clanking factory. The owners’ house was like a colonial mansion constructed of the local timber, with verandas and carved pillars draped with magnolias, and the Captain, the Valienté family, and a few other guests were invited down to drink orange liqueur. In the fields you could see the bent backs of the troll workers, and their song floated on the hot breeze.

The real tourist spectacle in the Corn Belt was the timber trade. Rafts of the stuff from the forests to the north were floated downstream on one Mississippi or another. At a waystation the rafts would be lifted out of the water by a twain or two, and then ganged together by trolls and human workers. The end result was one tremendous platform that might be an acre in size, suspended in the air, constructed of long straight trunks stripped and roped together, each held up by a squadron of airships. And off the twains would go, stepping across the worlds with their vast dangling freight, with parties of trolls and their human supervisors riding in huts and tents on the timber platforms. Just an astounding sight.

What was even more remarkable was what they saw going the other way. One of the principal exports of the Low Earths to the outer worlds was horses. So you’d see a twain descend, and the great ramps from the hold fold down, and out would trot a herd of young horses, supervised by cowboys on horseback.
