In 1861 Captain Sweet surveyed the harbour of "Pena Blanca" in South America, and had the honor of seeing the result of his labors placed on their charts by the British Admiralty. He gave up a sea-faring life in 1863, and emigrated to Queensland with his family with a view to embark in cotton growing. Failing, however, in that object, he came to Adelaide in 1867, and in February 1869, received from the Government of South Australia the appointment of Commander in H.M.C. Navy.

He next served three years as master mariner in the Black Diamond line, and in 1875 finally retired from the sea and settled in Adelaide. Since that period Captain Sweet has devoted his attention almost wholly to photography, and the views of scenery taken by him are unequalled ia their fidelity and beauty; in fact, as a landscape photographer he is unequalled in the colony.

In 1828 and the following year he, with his brother, the late
