Description:
Scarce hydrographic chart of Shark Bay West Australia, based on the original surveys by Captain Henry Mangles Denham (1800-1887). This chart was first issued January 18th 1864, large corrections 24th January 1921 and small corrections 1959.
The regular updating of Hydrographic charts by the Hydrographic Office was to ensure that commanders of ships, pilots and other mariners were able to have the most to up to date information available to safely navigate foreign waters and ports as new information of changes to sea depths, sand bars, wrecks or other any other pertinent nautical information that could hinder passage became available. As updated charts were offered for sale, the earlier outdated charts in the hands of mariners, pilots, ships owners and sailors were invariably discarded, subsequently making all British Admiralty issued hydrographic charts of the period rare.
Henry Mangles Denham (1800 - 1887)
Denham carried out major survey work around Australia and in the SW Pacific in the period 1852 to 1861 and reached rank of Admiral in the Royal Navy; Entered the navy at the age of 12; became dedicated to hydrographic work. Opened the port of Liverpool. Knighted and became F.R.S. in 1839. In 1854 (July 2): Capt Denham in HMS Herald came to complete a (chart) survey of the island of Raoul Sunday in NZ. The town of Denham in Australia is named after him.

Hydrographic charting of Australia History ( - )
Naval policy dictated that Admiralty charts be destroyed when superseded to avoid navigational error. It was during Rear Admiral John Washington’s period as the Admiralty’s hydrographer, 1855-1863, that a series of agreements were drawn up with the Australian colonies. These agreements provided boats and crews for use by officers lent from the Royal Navy to chart the coasts and shoal waters in the approaches to the rapidly developing towns, communication with which was seriously hampered by the the frequency of shipwrecks. It had been the discovery of gold and the consequent rush of miners and emigrants from not only England but California that added greatly the numbers of ships sailing to Australia’s east coast. This led to numerous petitions being made to Her Majesty’s Government to chart the eastern approaches to Australia to make for safer passage for shipping.
