This may have been partly because I don't know the Pilliga area at all and so found it difficult to picture the landscape Rolls describes in such loving and forensic detail. I did enjoy his respectful attention to the original First Nations inhabitants of the land, and the foreshadowing of Bill Gammage and Bruce Pascoe's later work in describing how this fertile territory resembled 'an English parkland' when first seen by explorers, ie lightly wooded, with low grass, for easy grazing and hunting of kangaroo and other game. It was the settlers who dramatically changed the character of the landscape by clearing the trees and then tearing up the fragile soil with the hard hoofs of cattle and sheep, which led to the scrub running wild and thick forest taking over.
First published in 1981, A Million Wild Acres is clearly a labour of love and must have taken decades of painstaking work to assemble. Rolls sets out the back and forth of land ownership over generations, recounts numerous anecdotes of bushrangers and wild cattlemen (including the tragic story of the Aboriginal outlaw Jimmy Governor -- the basis for Tom Kenneally's The Chant of Jimmy Blacksmith -- though Rolls describes Governor's life oddly as 'a sinister comedy'), and includes his own observations of flowering gums, bushfires, and wild creatures, birds and insects.
An admirable work, and I take my hat off to him, but I must admit I felt slightly exhausted by the end of it!
