So, for your amusement and mine, here is a half-related picture. In German, "Kohle" originally means coal or charcoal, but it is also used colloqiual to mean "money" (or dough, if you prefer the English colloquialism).
So here's a picture of me harvesting coal from a small charcoal kiln I ran together with some friends a few years ago. Making coal like that is quite a bit of work, but it's also a huge lot of fun! The coal in the basket I hold is the last remnant harvested, that is why there is so much straw mixed in.
It's dirty, dusty work, and that is why I am veiled like that. Coal is a good thing to have, but coal dust in the lungs not necessarily so...
