Apparently you can get your non-dwarf mayors if and only if there are more of the same species around. They're all very racist and hate each other you see, so they never socialize with other species. You have to have enough of them friends with the prospective mayor to outnumber the most popular dwarf.
Ah, that would explain it. Well, maybe I'll get lucky and get a breeding pair.
In other news, my baroness has mandated a cave fish leather item, the only thing I can't readily produce. I'm utilizing the bismuth bronze chains she mandated earlier in a jail for whatever poor sod takes the blame. First the cult thing, and now this... I'm starting to wonder about her.
My bridge across the mighty... whatever this river is called is nearly complete. Construction was delayed when a giraffe wandered onto the bridge for some reason- in order to keep dwarves from dodging into the river I dispatched my marksdwarves for some much needed archery practice. Almost as soon as the giraffe was dead a Forgotten Beast came. Due to the just-now-fixed bug where mud removes natural ramps, there isn't actually a way for anything to get to my cavern entrance. Sending the marksdwarves below resulted in a single line of text:

Good times. In other news, I just found out that the symbol of my civilization is a blade weed. My fortress government symbol is a quern. I detect subversive elements. It could be innocent, though, since clothing is my main export- my uniforms all specify emerald socks, even.
And finally, I've interred all of my ghosts. There hasn't been a pressing need since none of them were bitchy ghosts, and my dwarves are swooning over my lavish meals and legendary dining hall. I haven't even installed the mist machine yet.
