One massive room with very high ceilings, the textile mill is filled with
columns of large wooden frames holding strands of thread being woven one row
at a time.  Skilled workers operate the odd-looking contraptions so quickly
it's difficult to see how they work.  The mill produces everything from fine
silks to broadcloth for sails, quite a profitable operation.
