ACKNOWLEDGEMENTS

Our fieldwork in Baode was supported by The National Geographic Society, The Academy of Finland, and The Chinese Academy of Sciences. C. Badgley kindly made numerous improvements to the text, and L.L. Jacobs wrote the splendid plain-language summary. We are grateful to the editors for all their help and for this opportunity to pay tribute to Will Downs. Figure 10 shows our friends Will and Qiu Zhuding enjoying a meal and pleasant company in China.
