Gason, Samuel, The Dieyerie tribe of Australian Aborigines, Edited by George Isaacs., [W.C. Cox, Adelaide, 1874] 1st edition, 51pp, 8vo, handcover, with gilt title to spine., Complete, but with defects including an obtrusive ex libris label., Gason joined the South Australian Police in 1865 at the age of 23 and was stationed at Lake Hope. He was promoted to Mounted Constable 2nd class the following year. One of his most difficult tasks while at Lake Hope was negotiating with local Aborigines who were taking sheep from graziers, a conflict he seems to have managed with good sense. His tenure included the heavy flooding of 1870, during which he reported the deaths of 17 Aborigines. In 1871 Gason was transferred to Barrow Creek, where he witnessed the attack on the Telegraph Station.Gason's work was considered a most useful amateur contribution, and was used in the later compendium The Native Tribes of South Australia published in 1879.
