Tee and Mary, I've got you both down for a copy of the book. I'll be sure to let you know if I run across any.
Tee, the population has been very stable over the years, about 1800, give or take a few. Population totals vary from one village to the next, with the largest at about 600 and the smallest less than 100. South Amana currently stands at about 200. The population's composition has changed radically, however. I'm guessing that less than 40% are native born Amana folks anymore, my wife and I being two of them.
Sharon, I continue to be amazed that you've retained everything from your visit in such detail. You're right about the meaning of Tagelöhner. More literally translated, it means "those who are paid by the day." And that would be precisely the folks you mentioned.
Thank you for your comments, Christine. Glad to hear that you've learned something new. We erstwhile teachers always appreciate comments like that!
