Reg and Connie Donovan, 12, have lived all their lives at Orano, their father's sheep ranch. As the holidays after their last term of Correspondence School begin, there seems little except boarding school in the future, but a visit from Uncle Ben, black sheep of the family, proves adventurous. He comes with a band of drovers whose cook, Nobby, makes friends with Connie and tells her of a man of a gold mine that he must deliver to a certain Mrs. Sleeman. The elements involved- Nobby's death and the clearing of his dog Rusty from a sheep killing charge, the recovery of the map from a man who had stolen it, the settling of Uncle Ben's unsettled smourlend themselves to natural story telling. But the value here lies more in the life-like characterizations of Australians and their ranching, for the plot is an ordinary one that suggests little of the harsh naturalism of Daphne Rooke's Mittee and other South African novels.
