modern geometry
     
     consider that the girder
     might not need to be level but
     must angle across the intervening
     space however irregular
     
     send a probe out my way
     find out if we are
     plumb or offset and
     what length will span us
     
     no equity is guaranteed --
     we each construct the part we can
     and accept the implications
     if the center doesn't hold
