“Madeira, the town of Funchal, and the eastern end of the island” 1842


“Madeira, the town of Funchal, and the eastern end of the island”. Porcher, Edwin Augustus. April 1842. National Library of Australia. [1]

Commander Edwin Augustus Porcher (1824-1878) was a naval officer and draughtsmen.[2]  He was a member of the four year voyage of the H.M.S. Fly (1842-1846), commanded by Captain F. P. Blackwood, which made a hydrographic survey of the north-east coast of Australia and other islands.  Throughout this survey, Porcher made a number of watercolor views of places they visited, including the picture of Madeira featured in this post.

The H.M.S. Fly was to make a specific survey of the Great Barrier Reef to discover gaps through which ships could pass.  Without accurate charts, ships would continue to be lost.  Before the survey could begin, the H.M.S Fly was to visit Madeira to verify the rates of her chronometers.[3]

Chronometers were required to calculate longitude.  Chronometers did not keep perfect time so it was important to measure how much time they lost or gained per day.  This rate would then be used for a more accurate calculation.  Madeira was the island of choice for the British Board of Longitude determined the longitude of Madeira in 1822.  Thus the H.M.S. Fly with her tender the Bramble schooner, arrived at Madeira on April 18, 1842 where they spent the next few days calibrating their chronometers.  We do not know of Porcher drank any Madeira, presumably he did.  His journals survive in the National Library of Australia so perhaps someone can take a look!
