I'd like to see a pic of those treacle mines, too, Graham. And I'm EXTREMELY hurt and disappointed that you did not conduct me to them during our visit. I'm a HUGE fan of treacle mines, and in fact have modified my gold detector to respond to treacle deposits. I can let you use it when you are here. In fact, I will insist that you do, and I will let you wear my treacle-hunting kit complete with dun-colored pith helmet as well.
