Guv Fetch, you seemed to not understand the option (of Robboo in the Further Expansion? thread) of reducing food production in BW instead of whipping. Sorry if you have it sorted, or if I am overstepping the mark, but take a look at the
cartography office here and take a look at BW's city screenshot. Actually, this shot might be a litle outdated, but the idea is th same.
BW is producing 20 food, and only eating 18. So if you want to slow its growth, make it produce 19, or to stop it, 18. Of course anything less would starve it (which may be an option for unhappiness). If you wanted to pump out production, you could put all citizens on mines and forests, increasing hammers from 8 to 12. However, commerce and food would suffer, and while food wouldn't matter, the commerce would, as BW is holding up the economy at the moment - so you want to try to keep working the cottages. Here's an option:
Move the worker from the pigs to a forest, and move one scientist to a forest.
This would give you a neutral food situation and 2 extra hammers for the market or granary, or whatever you want to build. There are other options, but you are in a tougher position in the capital. Anyway, hope it helps (if you needed it). Keep up the good work.
EDIT:

I just noticed that it's a very poor example (it's late), you'd work the plains hill forest and plains forest for more hammers (this would also change the food intake), but you get the picture.
