It’s been both quiet and busy here, these last few weeks. It’s
fall, now, and harvest season for several local vegetables. The La’helis don’t
sell vegetables, but they do have a garden for their own use, and they’ve been
busy harvesting. The new orchardist is also busy planning crabapple crosses
ahead of the flowering season. The heat is starting to back off a bit, and the
days are noticeably shorter, but it doesn’t look
like fall in any sense I am used to. No leaves are falling. The trees
here are all evergreen, as I think I’ve
mentioned before.
Not much is going on, other than the harvest and our
preparations for our trip. Ka’te can go, we got that settled out. But I thought
I’d take the opportunity of little news to describe something the ethnic Imperials
have unquestionably given this country, since I have otherwise painted them in
an unflattering light. It’s a little, local thing, but a fairly good example of
how things work around here.
All the larger towns and cities in this country were
originally Imperial settlements. The local cultures preferred a more dispersed
settlement pattern, and their cultural descendants are still mostly rural
people (hence “country folk”). Since the Imperials were dependent on water
transportation, all the cities and towns are along navigable rivers, including
the town that I go into to do my shopping. The river wouldn’t quite count as navigable
to us, but it is big enough for the Myrmeoid barges, which only need about 40
centimeters to float.
But, the town does not rely on water only for
transportation. They also use the water to generate a modest amount of
electricity and some mechanical power for mills, and for that they need dams.
But dams would cut off the runs of various fishes that come up from the sea to
breed, among other problems. On Earth, we ran into the same problem, of course,
and decided to sacrifice the fishes, precipitating various political and
technical struggles over the following
generations. We’re still dealing with this, centuries later. But in this
country at least, they did something different, and it was the Imperials who
did it.
Imperial food culture is based mostly on fish, since they
were an island culture originally. They prefer oceanic fish, but of course once
you get inland, freshwater fish are cheaper. The fish runs were a major part of
the local culture and economy, and the upstream towns refused to allow their
supply of fish to be cut off. The solution they finally hit on was to build a
canal several kilometers long, along an old, silted-in river channel. At the top, the canal takes water from the river,
but the bottom of the canal is higher than the bottom of the river so that in a
drought it is the canal, not the river, that will run dry. Then there is a
series of eight dams along the canal. Each dam takes half a day to empty before
the spillway must be closed so the reservoir can refill, so some of the dams
are paired; two supply electricity to the hospital, and two supply electricity
to the communications tower and the police station and jail. The other four
supply mechanical and electrical power to factories and mills. The workers rest
while their dam recharges.
But at the bottom of the canal, this big pulse of water has
to rejoin the river, and it used to make the water level very variable in a way
that caused environmental problems. The solution lay in more engineering, but
not by Myrmeoids—they brought in this planet’s equivalent of beavers.
These are, of course, snakelike animals covered with short,
mottled brown feathers. They’re about three meters long. They have big front
teeth, like beavers, which they use to fell small trees and also to cut
channels through the marshes that form at the edges of the ponds behind their
dams. Unlike beavers, though, they don’t eat bark. Instead, they eat a
particular kind of fish that lives only in these ponds. The people encouraged the
fish-beavers to move in by splitting the bottom of the canal into several
smaller canals, of the size fish-beavers prefer. They also fenced off certain
areas so that the fish-beavers would not be able to use the whole thing at the
same time. Then when the first dams were exhausted, the fish-beavers could move
to the areas that had been fenced while the first impoundments grew back.
Within a few years, the bottom of the canal became a huge marsh that evened out
the flow of water, something like a giant sponge might. Mosquitoes love it, of
course, but then the dozens of kinds of gorgeous dragonflies love the
mosquitos, and the town makes a lot of money from tourists who come to the
marsh for recreational hunting—of dragonflies. The people train their pet
house-wasps like falcons.
Imperial culture does this sort of thing a lot. We have a
history of trying to solve one problem and in the process creating three more.
Myrmeoids can certainly make the same
kinds of mistakes. But it is part of the Imperial culture to, as they would put
it, “study the enemy and the battlefield before committing troops.” They don’t
always agree with other peoples (or each other) about what really constitutes a
problem, but once they decide to attack a problem, they study the matter very
carefully. They anticipate better than we do.
