I've the original German version of this book of this Swiss photographers' work. In part, it describes agricultural development in the US and artisitacally records the field/land forms. It documents the development of center-pivot irrigation, the patent of which was from a Swiss-American, Frank Zeiback of Columbus, NE. It is a huge work. V.
