With the help of many interested and open minded people I was able to realise this impressive project. I owe a huge debt of thanks to all of them. In particular I would like to thank:
Tamara Watson from Adelaide, who gave me indispensable information and contacts.
Terrence Coulthard from Iga Warta, who entrusted me with the the sacred ochre of the ADNYAMATHANHA in a moving ceremony.
Sandra Taylor from Coober Pedy, who enabled entry to the land of the ANTAKIRINJA MUTUNTJARA for me.
Marie Elena Ellis, who dug the SOIL of the AMWENGKWERNE in Amoonguna by herself.
Junior Juppurrula Frank, who received me brotherly in Nyinkka Nyunyu and with whom I drove through the land around Tennant Creek, excavating the SOIL of the WARUMUNGU on the way.
Balany Bolgi, Roland Ashley and John (Longjohnny) Dewar, who allowed me to dig the SOIL in Manyallaluk.
And Georgie Walton Cunhill, with whom I excavated the SOIL of the MURRUMBUR in the Kakadu National Park.
My thanks also go to Birgit Scheps from Leipzig, Germany, who introduced me in the culture of the Aboriginal people and arranged concrete contacts in Australia, as well as Christiane Fenell from Eddelak, Germany, who always stood beside me in word and deed.
