This series comprises personal correspondence to and from Tindale for the period 1922. A large part of correspondence within this series centres on the 1921-1922 expedition to Groote Eylandt, in the Gulf of Carpentaria, which Tindale undertook in conjunction with the Church Missionary Society of Australia and Tasmania.
Correspondence reflects the wealth of ethnological objects and entomological specimens obtained from Groote Eylandt (NT) and Roper River (NT) during this expedition. The series contains a number of memorandums issued by the Public Library, Museum, and Art Gallery of South Australia, including Edgar Ravenswood Waite (see AA356) and Hately Waddell Marshall, commending Tindale for his contribution to the Museum's natural history collection.
The series also contains receipts and invoices for the packing and freight of objects and specimens from Groote Eylandt (NT) to the South Australian Museum (SA); specimen inventory; valuations; and expenses associated with the expedition.
Correspondence has been arranged in chronological order.
