I lost all my notes (again), so here's a quick summary of what I did:
Moved to 31.23.
Lost about 70 dwarves to FB infection/thirst.
Fixed the food situation (really, setting stills on repeat with 500+ drinks and 0 food isn't such a good idea).
Cleaned up the entrance.
Moved the hospital to a more respectable location.
Made a working militia (though most of it died earlier, so it is mostly untrained dwarves now).
Made a shitload of coffins.
Started adamantine mining.
Added the traditional merchant-capturing machine. (Above the entrance. For it to work, link all supports under walls (but not in barracks!) to a single lever and pull it when merchants are passing on cage traps. Voila - caged merchants! Read my turn in Failcannon or New Eternal Halls for more in-depth description)
Killed a couple of FBs (someone must detect where they are entering the fortress).
Walled off a few unused sections (precioussss FPSsss).
Expanded the farms and moved them to the bottom of the waterfall.
Destroyed the roof above pastures and made temporary ones on the mountain (the grass wasn't regrowing under the roof).
Got a couple of strange moods, nothing useful (mechanism, amulet and other shit).
Added an emergency shutoff lever (closes off the entrance).
Made a trade/war entrance switch (the 'on' position is war (intruders go through a mini-version of maim-o-matic on brook), 'off' is trade (traders go through the capturing machine).
Replaced the grate on bottom of maim-o-matic with hatch to drown all goblins who aren't killed by fall. It is linked to a lever one level above (I forgot to make a note there).
Things for the next overseer to do:Make lots of iron for mini-maim-o-matic on the brook (I built one trap, hopefully you'll figure out the pattern).
Get wood (there're elves in depot, trade or seize some) for beds and cages.
Link the supports in my machine to some lever.
Be careful with tantrums and insanities, make dwarves happy.
Look at FB situation.
Produce
adequate steel equipment for the squads.
Destroy the rest of the ceiling over pasture and move the cattle there once grass regrows.
Make soap for the hospital.
Look at what plants we're growing and build some aboveground plots. I've mainly grown plump helmets for food and drinks and cave wheat for drinks, but more variety would be awesome.
Make some mechanisms.
Finish the cage traps around the supports.
Link the floodgate and the hatch at the bottom of the maim-o-matic to the lever on the level above.
Here's the save. Have Fun!
