Hi everyone! Wow, I don't know if I'll be able to catch up with all these messages and figure out who's done what and when!
Ad - I don't think you have to make the explanations too complicated, they just want the kids to understand the concept of the metaphor.
Grünes Feuer would be one - every bush/shrub a green fire or alight with green fire
Flammenhügel another one - flames + hills = hills being lit up by the sunset
But the last two lines are really more of a simile - when the wind touches/fans the hills of fire, the dust forms clouds of golden smoke. So the wind blows, kicks up the dust on the hills and the sunlight reflecting on it makes it look like golden smoke Or something. 
I suppose you could make a metaphor out of it in a pinch.
I think the whole deal is that he's making it seem like everything's on fire when it really isn't.
Ahhhh, just found this which explains it quite well - www.britting.de/Sekund/Schug.pdf
You can click on the name of the poem on the left side bar and it tells you a bit about it.
Canella - yeah, if it's a new quarter, you need a new referral even if you've visited that doctor before. You can either get one from your GP, or pay the EUR 10 and get a referral from the specialist back to your GP for further use in that quarter.
Will read more later!
