private exploration parties. Hamilton was a noted horseman, and placed great importance on mounted constabulary during his time as Commissioner, which made a career with the police an attractive choice for bright adventurous young men. He was a stern disciplinarian and developed the police force into a well-drilled and efficient service. He never failed to punish infractions, nor to give credit for good work. He was not only a great supporter of the artistic merits of photography, but could also see its benefit in police investigations. In the late 1860s he introduced the science of photography to the South Australia Police, appointing Detective Von Der Borch as its official photographer. This was followed in 1880 by his introduction of the scientific analysis of handwriting, appointing Detective Peter Webster as the first handwriting expert. In 1881 he took one year's leave of absence prior to resignation, and was replaced by W. J. Peterswald. From the day he first set foot in Australia he never left the country. He was closely associated with the vice-regal staff, acting as aide-de-camp on occasion and at the time of his death was serving as extra aide-de-camp of Sir William Robinson. Lake Hamilton on Eyre Peninsula bears his name. Artistic and Literary Interests Hamilton's published writings include poetry, essays, verse, and reminiscences. His drawings were often imbued with a somewhat whimsical characterisation. He became something of an authority on art, and was a keen amateur artist. Penman and Galbraith published a collection of his lithographs depicting conflict between European and Aboriginal people. It was reported in 1883 that he had purchased, for £2,000, William Strutt's 1864 painting "Black Thursday" for permanent loan to the South Australian Art Gallery, although this sale may not have been finalised. He was foremost in the foundation of the Adelaide Club, and actually resided there in his retirement. He was an active member of the Acclimatization and Zoological Society.

Members of his extended family served with distinction in the British Army over several generations, some being elevated to the peerage. He was an elder brother of Maj. Gen.

Gilbert Henry Claude Hamilton, CB, General Sir Bruce Meade Hamilton, GCB, KCB, KCVO., and Major General Hubert Ion Wetherall Hamilton, CB, CVO, DSO. His other brothers were Dr.
