There is a new book on South African mills by Chester O. Staples which has just been published.
Called "Mills of Southern Africa" the book is the result of a number of years research travelling round South Africa
discovering and recording that country's mills - driven by wind, water or horse.
The book is available direct from the publishers
Umdaus Press.
There is a linked website
Mills of Southern Africa, which includes a couple of
tours of the mills of the North West Province, South Africa, and the Free State, South Africa.
