The building blocks of industrial civilization were
geologic in origin -- coal, steel, oil and aluminum -- so the most important
trade routes usually connected different geologic zones. The building blocks of
the Middle Ages, however, are more likely to be biologic -- wood, leather, wool
and wine -- so the principle trade routes nowadays connect different biologic
zones. They most often run north to south, swapping the sugar, cotton and
tobacco of the long sub-tropical growing season for the soft, thick fur and wool
of the colder north. Other routes move from the salt pans and ranches of the
arid west to the farmlands of the moist east. There is very little trade across
the Appalachians because the inhabitants of each side have access to pretty much
the same catalog of crops, and there's no big need to shuffle things around.
The focal point of the North American trade network is New Orleans, where
the continent's primary river pours into an inland sea. Here coffee, cocaine,
balsa and rubber from South America is stockpiled in warehouses along side
leather from Texas, cotton from Tennessee and
SALT: The human need for salt is met in most places by channelling sea
water into wide, shallow pond and allowing the water to evaporate, leaving
behind a crusty film of salt. In the Midwest, however, they have no convenient
sea from which to get their salt water, so it has to be imported from far away.
Much of it comes up the Missisippi from the arid coast of Texas where salt dries
more quickly than it does along the more humid coast of Louisiana, but an even
better source is Utah where ancient lakebeds in the
desert are mined for their vast deposits. It is therefore vital to
Midwesterners that the road to Utah stay open, and the merchants of St. Louis
spend a great deal of money placating the nomadic tribes of Nebraska in order to
guarantee safe passage of their caravans. This influx of cash has made the
Rizzini tribe among the most affluent and civilized of all the plainsmen.
